OUR BUSINESS
 
We provide an integrated suite of clinical infrastructure and workflow
automation solutions for healthcare facilities. These solutions include pharmacy
and supply systems, clinical reference tools, an Internet-based procurement
application and decision support tools. We sell and lease our products and
related services to a wide range of healthcare facilities such as hospitals,
integrated delivery networks and specialty care facilities, which include
nursing homes, outpatient surgery centers, catheterization labs and clinics. As
of March 31, 2001, we had installed over 18,600 pharmacy and supply systems in
over 1,100 healthcare facilities in the United States. In 2000, we generated
revenue of $67.4 million from the sale and lease of our products and related
services.
 
Our solutions enable healthcare facilities to acquire, manage, dispense and
deliver pharmaceuticals and medical supplies more effectively and efficiently.
Our pharmacy and supply systems facilitate the distribution of pharmaceuticals
and medical supplies at the point of care. These systems interface with
healthcare facilities' existing information systems to accurately capture and
display critical patient data. Our Internet-based procurement application
automates and integrates healthcare facilities' requisition and approval
processes. Furthermore, our Internet-enabled decision support product allows
healthcare facilities to monitor trends in drug utilization and diversion,
improve regulatory compliance and reduce costs by monitoring usage patterns and
optimizing product management. When used in combination, our products and
services offer a comprehensive clinical infrastructure and workflow automation
solution for healthcare facilities.
 
OUR MARKET
 
The delivery of healthcare in the United States is dependent upon predominantly
manual and paper-based methods, resulting in a highly fragmented, complex and
inefficient system. A primary cause of this inefficiency is the relatively small
investment made by healthcare facilities in information technology in the last
two decades. Many existing healthcare information systems are unable to support
the modernization of healthcare delivery processes and address patient safety
initiatives. These factors have contributed to medical errors and unnecessary
process costs across the sector.
 
The Institute of Medicine highlighted the prevalence of medical errors in a
November 1999 report based on the results of more than 30 independent studies.
The report indicated that medical errors are among the top ten causes of death
in the United States, and that medication errors specifically were responsible
for more than an estimated 7,000 deaths in 1993. In March 2001, the Institute of
Medicine issued a follow-up report that recommended increased investment in
information technology as a means of reducing medical errors and improving the
overall quality of patient care.
 
Economic pressures have also dramatically impacted patient care by reducing the
flow of funds to healthcare providers and facilities. For example, the passage
of the Balanced Budget Act of 1997 proposed a reduction of payments to
healthcare providers by more than $250 billion over a five-year period.
Continuing consolidation in the healthcare industry and shortages in the U.S.
labor market for healthcare professionals have also significantly impacted
patient care and contributed to the pressures faced by healthcare providers and
facilities.

OUR SOLUTIONS
 
Our clinical infrastructure and workflow automation solutions are designed to:
 
    - reduce medication errors;
 
    - reduce costs;
 
    - improve operating efficiency;
 
    - leverage investments in existing information systems;
 
    - simplify the process of ordering pharmaceuticals and medical supplies; and
 
    - monitor utilization trends.
 
OUR STRATEGY
 
Our goal is to become the leading provider of clinical infrastructure and
workflow automation solutions for the healthcare industry by focusing on the
following strategies:
 
    - continue to leverage and extend our solutions to address patient safety
      and cost-containment pressures facing healthcare facilities;
 
    - continue to collaborate with leading healthcare providers in the
      definition, development and deployment of our products and services;
 
    - further penetrate our installed customer base, which to date has purchased
      only a subset of our available products and services;
 
    - develop solutions that enhance our customers' existing systems by
      preserving, leveraging and upgrading their existing information systems;
      and
 
    - develop strategic relationships with other healthcare and non-healthcare
      partners to enhance our product offerings, broaden our automation
      solutions and increase our sales opportunities.
 
OUR HISTORY
 

We have financed our operations since inception primarily through the private
placement of equity securities, as well as through equipment financing and
secured loan arrangements. Through March 31, 2001, we have raised approximately
$81.0 million from the private placement of equity securities, net of
redemptions. This includes net proceeds of approximately $28.5 million from our
last equity financing in the first quarter of 2000. As of March 31, 2001, our
accumulated deficit was approximately $94.6 million, and in 1999 and 2000, we
had net losses of $26.3 million and $20.8 million, respectively.

 
We were incorporated in California in September 1992 under the name OmniCell
Technologies, Inc. In September 1999, we changed our name to Omnicell.com. We
intend to reincorporate in Delaware and change our name to Omnicell, Inc.
immediately prior to the completion of the offering.

RECENT OPERATING RESULTS
 
Total revenues increased 27.3% from $16.4 million for the quarter ended
June 30, 2000 to $20.8 million for the quarter ended June 30, 2001 due to an
increase in the number of pharmacy and supply systems installed. Our loss from
operations decreased 78.0% from $4.3 million for the quarter ended June 30, 2000
to $0.9 million for the quarter ended June 30, 2001 primarily due to increased
gross profit and decreased spending on our Internet-based procurement
application.
 
Cash, cash equivalents and short-term investments decreased $3.0 million from
$7.7 million as of March 31, 2001 to $4.7 million as of June 30, 2001. As of
June 30, 2001, we had borrowed $3.0 million under our credit facility, were
eligible to borrow an additional $5.0 million and were in compliance with the
covenants of the credit facility.

                                  RISK FACTORS
 
YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS BEFORE YOU DECIDE TO
BUY OUR COMMON STOCK. YOU SHOULD ALSO CONSIDER THE OTHER INFORMATION IN THIS
PROSPECTUS. IN ADDITION, THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE
ONLY ONES FACING US BECAUSE WE ARE ALSO SUBJECT TO ADDITIONAL RISKS AND
UNCERTAINTIES NOT PRESENTLY KNOWN TO US. IF ANY OF THESE RISKS ACTUALLY OCCURS,
OUR BUSINESS, FINANCIAL CONDITION, OPERATING RESULTS OR CASH FLOWS COULD BE
SERIOUSLY HARMED. THIS COULD CAUSE THE TRADING PRICE OF OUR COMMON STOCK TO
DECLINE, AND YOU MAY LOSE PART OR ALL OF YOUR INVESTMENT.
 
RISKS RELATED TO OUR BUSINESS
 
ANY REDUCTION IN THE GROWTH AND ACCEPTANCE OF OUR PHARMACY AND SUPPLY SYSTEMS
AND RELATED SERVICES WOULD HARM OUR BUSINESS.
 
Our pharmacy and supply systems represent a relatively new approach to managing
the distribution of pharmaceuticals and supplies at healthcare facilities. Many
healthcare facilities still use traditional approaches that do not include
automated methods of pharmacy and supply management. As a result, we must
continuously educate existing and prospective customers about the advantages of
our products. Our pharmacy and supply systems typically represent a sizeable
initial capital expenditure for healthcare organizations. Changes in the budgets
of these organizations and the timing of spending under these budgets can have a
significant effect on the demand for our pharmacy and supply systems and related
services. In addition, these budgets are often characterized by limited
resources and conflicting spending priorities among different departments. Any
decrease in expenditures by these healthcare facilities, particularly our
significant customers, could decrease demand for our pharmacy and supply systems
and related services and harm our business. We cannot assure you that we will
continue to be successful in marketing our pharmacy and supply systems or that
the level of market acceptance of such systems will be sufficient to generate
operating income.
 
THE HEALTHCARE INDUSTRY FACES FINANCIAL CONSTRAINTS AND CONSOLIDATION THAT COULD
ADVERSELY AFFECT THE DEMAND FOR OUR PRODUCTS AND SERVICES.
 
The healthcare industry has faced, and will likely continue to face, significant
financial constraints. For example, the shift to managed care in the 1990s put
pressure on healthcare organizations to reduce costs, and the Balanced Budget
Act of 1997 significantly reduced Medicare reimbursement to healthcare
organizations. Our automation solutions often involve a significant financial
commitment by our customers, and, as a result, our ability to grow our business
is largely dependent on our customers' information technology budgets. To the
extent healthcare information technology spending declines or increases more
slowly than we anticipate, demand for our products and services would be
adversely affected.
 
Many healthcare providers have consolidated to create larger healthcare delivery
organizations with greater market power. If this consolidation continues, it
could erode our customer base and could reduce the size of our target market. In
addition, the resulting organizations could have greater bargaining power, which
may lead to price erosion.
 
Sun Healthcare Group, Inc., a customer that has accounted for a significant
percentage of our sales over the past five years, filed for Chapter 11
bankruptcy protection in 1999. Revenues from Sun Healthcare were significantly
reduced in 2000, and we do not expect any purchases of our products and services
by Sun Healthcare in 2001 or future years.
 
                                       6

THE CLINICAL INFRASTRUCTURE AND WORKFLOW AUTOMATION MARKET IS HIGHLY COMPETITIVE
AND WE MAY BE UNABLE TO COMPETE SUCCESSFULLY AGAINST NEW ENTRANTS AND
ESTABLISHED COMPANIES WITH GREATER RESOURCES.
 
The clinical infrastructure and workflow automation market is intensely
competitive and is characterized by evolving technologies and industry
standards, frequent new product introductions and dynamic customer requirements.
We expect continued and increased competition from current and future
competitors, many of whom have significantly greater financial, technical,
marketing and other resources than we do. Our current direct competitors in the
clinical infrastructure and workflow automation market include Pyxis Corporation
(a division of Cardinal Health) and Automated Healthcare (a division of
McKessonHBOC).
 
The competitive challenges we face in the clinical infrastructure and workflow
automation market include, but are not limited to:
 
    - Our competitors may develop, license or incorporate new or emerging
      technologies or devote greater resources to the development, promotion and
      sale of their products and services.
 
    - Certain competitors have greater name recognition and a more extensive
      installed base of pharmacy and supply systems or other products and
      services, and such advantages could be used to increase their market
      share.
 
    - Other established or emerging companies may enter the clinical
      infrastructure and workflow automation market.
 
    - Current and potential competitors may make strategic acquisitions or
      establish cooperative relationships among themselves or with third
      parties, including larger, more established healthcare supply companies,
      thereby increasing their ability to develop and offer products and
      services to address the needs of our prospective customers.
 
    - Our competitors may secure products and services from suppliers on more
      favorable terms or secure exclusive arrangements with suppliers or buyers
      that may impede the sales of our products and services.
 
Competitive pressures could result in price reductions of our products and
services, fewer customer orders and reduced gross margins, any of which could
harm our business.
 
WE HAVE A HISTORY OF OPERATING LOSSES AND WE CANNOT ASSURE YOU THAT WE WILL
ACHIEVE PROFITABILITY.
 
For 1996 and 1997, we incurred net losses of approximately $10.5 million and
$10.2 million, respectively. We had net income of approximately $0.6 million in
1998 and had net losses of $26.3 million and $20.8 million in 1999 and 2000,
respectively. As of March 31, 2001, we had an accumulated deficit of
approximately $94.6 million. There can be no assurance we will achieve
profitability in the future. Even if we achieve profitability, we may not be
able to sustain or increase profitability on a quarterly or annual basis.
 
IF WE FAIL TO MANAGE OUR GROWING AND CHANGING OPERATIONS, OUR COMPETITIVE
POSITION, RESULTS OF OPERATIONS AND FINANCIAL CONDITION COULD BE HARMED.
 
During 2000, we experienced a period of significant fluctuation in our number of
employees and expansion of the scope of our operating and financial systems.
This has resulted in new and increased responsibilities for management
personnel. To accommodate our changing operations, compete effectively and
manage potential future growth, we must continue to implement and improve our
information systems, procedures and controls, and we must hire competent and
qualified personnel. In addition, we must train, motivate and manage our
workforce to meet the increasing challenge of expanding our automation solutions
business. These demands will require the addition of new management personnel
and the training of existing management personnel, including information
 
                                       7
<Page>
systems, sales, technical, service support and financial reporting personnel. We
cannot assure you that our personnel, systems, procedures and controls will be
adequate to support our future operations. Failure to manage our growing and
changing operations could harm our competitive position, results of operations
and financial condition.
 
OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY AND MAY CAUSE OUR
STOCK PRICE TO DECLINE.
 
Our quarterly operating results have varied significantly in the past and may
vary significantly in the future depending on many factors that may include, but
are not limited to, the following:
 
    - the size and timing of orders for our pharmacy and supply systems, and
      their installation and integration;
 
    - the overall demand for healthcare clinical infrastructure and workflow
      automation solutions;
 
    - changes in pricing policies by us or our competitors;
 
    - the number, timing and significance of product enhancements and new
      product announcements by us or our competitors;
 
    - the relative proportions of revenues we derive from products and services;
 
    - our customers' budget cycles;
 
    - changes in our operating expenses;
 
    - the performance of our products;
 
    - changes in our business strategy; and
 
    - economic and political conditions, including fluctuations in interest
      rates and tax increases.
 
Due to the foregoing factors, our quarterly revenues and operating results are
difficult to forecast. Revenues are also difficult to forecast because the
clinical infrastructure and workflow automation market is rapidly evolving.
 
The purchase of our pharmacy and supply systems is often part of a customer's
larger initiative to re-engineer their pharmacy, distribution and materials
management systems. As a result, the purchase of our pharmacy and supply systems
generally involves a significant commitment of management attention and
resources by prospective customers and often requires the input and approval of
many decision makers, including pharmacy directors, materials managers, nurse
managers, financial managers, information systems managers, administrators and
boards of directors. For these and other reasons, the sales cycle associated
with the sale or lease of our pharmacy and supply systems is often lengthy and
subject to a number of delays over which we have little or no control. We cannot
assure you that we will not experience delays in the future. A delay in, or loss
of, sales of our pharmacy and supply systems could cause our operating results
to vary significantly from quarter to quarter and could harm our business.
Accordingly, we believe that period-to-period comparisons of our operating
results are not necessarily indicative of our future performance. Although we
recently experienced revenue growth, this growth should not be considered
indicative of future revenue growth, if any, or of future operating results.
Fluctuation in our quarterly operating results may cause our stock price to
decline.
 
IF WE ARE UNABLE TO RECRUIT AND RETAIN SKILLED AND MOTIVATED PERSONNEL, OUR
COMPETITIVE POSITION, RESULTS OF OPERATIONS AND FINANCIAL CONDITION COULD BE
HARMED.
 
Our success is highly dependent upon the continuing contributions of our key
management, sales, technical and engineering staff. We believe that our future
success will depend upon our ability to attract, train and retain highly skilled
and motivated personnel. In particular, we will need to hire a number of
information technology, research and development, programming and engineering
personnel
 
                                       8
<Page>
to assist in the continued development of our business. As our products are
installed in increasingly complex environments, greater technical expertise will
be required. As our installed base of customers increases, we will also face
additional demands on our customer service and support personnel, requiring
additional resources to meet these demands. We may experience difficulty in
recruiting qualified personnel. Competition for qualified technical,
engineering, managerial, sales, marketing, financial reporting and other
personnel is intense and we cannot assure you that we will be successful in
attracting and retaining qualified personnel. Competitors have in the past
attempted, and may in the future attempt, to recruit our employees. Failure to
attract and retain key personnel could harm our competitive position, results of
operations and financial condition.
 
IF WE ARE UNABLE TO MAINTAIN OUR RELATIONSHIPS WITH GROUP PURCHASING
ORGANIZATIONS OR OTHER SIMILAR ORGANIZATIONS, WE MAY HAVE DIFFICULTY SELLING OUR
PRODUCTS AND SERVICES.
 
We have agreements with various group purchasing organizations, such as Premier,
Inc., Novation, LLC and Consorta Catholic Resources Partners, that enable us to
more readily sell our products and services to customers represented by these
organizations. Our relationships with these organizations are terminable at the
convenience of either party. The loss of our relationship with Premier, for
example, could impact the breadth of our customer base and could impair our
ability to increase our revenues. We cannot guarantee that these organizations
will renew our contracts on similar terms, if at all, and we cannot guarantee
that they will not terminate our contracts before they expire.
 
WE DEPEND ON A LIMITED NUMBER OF SUPPLIERS FOR OUR PHARMACY AND SUPPLY SYSTEMS
AND OUR BUSINESS MAY SUFFER IF WE ARE UNABLE TO OBTAIN AN ADEQUATE SUPPLY OF
COMPONENTS AND EQUIPMENT ON A TIMELY BASIS.
 
Our production strategy for our pharmacy and supply systems is to work closely
with several key sub-assembly manufacturers and utilize lower cost manufacturers
whenever possible. Although many of the components of our systems are
standardized and available from multiple sources, certain components or
subsystems are fabricated according to our specifications. At any given point in
time, we may only use a single source of supply for certain components. Our
failure to obtain alternative vendors, if required, for any of the numerous
components used to manufacture our products would limit our ability to
manufacture our products and could harm our business. In addition, any failure
of a maintenance contractor to perform adequately could harm our business.
 
WE DEPEND ON SERVICES FROM THIRD PARTIES TO SUPPORT OUR PRODUCTS, AND IF WE ARE
UNABLE TO CONTINUE THESE RELATIONSHIPS AND MAINTAIN THEIR SERVICES, OUR
COMPETITIVE POSITION, RESULTS OF OPERATIONS AND FINANCIAL CONDITION COULD BE
HARMED.
 
Our ability to develop, manufacture and support our existing products and any
future products depends upon our ability to enter into and maintain contractual
arrangements with others. We currently depend upon services from a number of
third-party vendors, including Dade Behring Inc., to support our products. We
cannot be sure that we will be able to maintain our existing or future service
arrangements, or that we will be able to enter into future arrangements with
third parties on terms acceptable to us, or at all. If we fail to maintain our
existing service arrangements or to establish new arrangements when and as
necessary, our competitive position, results of operations and financial
condition could be harmed.
 
IF WE ARE UNABLE TO SUCCESSFULLY INTEGRATE OUR AUTOMATION SOLUTIONS WITH THE
EXISTING INFORMATION SYSTEMS OF OUR CUSTOMERS, THEY MAY CHOOSE NOT TO USE OUR
PRODUCTS AND SERVICES.
 
For healthcare facilities to fully benefit from our automation solutions, our
systems must integrate with their existing information systems. This may require
substantial cooperation, investment and coordination on the part of our
customers. There is little uniformity in the systems currently used by our
customers, which complicates the integration process. If these systems are not
successfully
 
                                       9
<Page>
integrated, our customers could choose not to use or to reduce their use of our
automation solutions, which would harm our business.
 
ANY DETERIORATION IN OUR RELATIONSHIP WITH COMMERCE ONE WOULD ADVERSELY AFFECT
OUR INTERNET-BASED PROCUREMENT CAPABILITIES.
 
We have entered into an agreement with Commerce One, Inc., a provider of
business-to-business technology solutions that link buyers and suppliers of
goods and services to trading communities over the Internet. Our agreement with
Commerce One enables us to implement a customized version of Commerce One's
BuySite software at customer sites. We cannot be sure that Commerce One will not
license its BuySite technology to our competitors. We cannot guarantee that
Commerce One will be able to develop and introduce enhancements to its products
that keep pace with emerging technological developments and emerging industry
standards. Moreover, we cannot guarantee that the Commerce One network will not
experience performance problems or delays. The failure by Commerce One in any of
these areas could harm our Internet-based procurement capabilities.
 
OUR FAILURE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS COULD ADVERSELY AFFECT
OUR ABILITY TO COMPETE.
 

We believe that our success will depend in part on our ability to obtain patent
protection for products and processes and our ability to preserve our
trademarks, copyrights and trade secrets. We have pursued patent protection in
the United States and foreign jurisdictions for technology that we believe to be
proprietary and for technology that offers us a potential competitive advantage
for our products, and we intend to continue to pursue such protection in the
future. We currently own eleven U.S. patents, two of which are co-owned. In
addition, we currently have one U.S. patent allowed and awaiting issue and six
U.S. patents in application. The issued patents relate to various features of
our pharmacy and supply systems. There are other issued patents and applications
in process in Australia, Japan, Hong Kong, Canada and European countries related
to issued and pending applications in the United States. There can be no
assurance that we will file any patent applications in the future, that any of
our patent applications will result in issued patents or that, if issued, such
patents will provide significant protection for our technology and processes.
Furthermore, there can be no assurance that others will not develop technologies
that are similar or superior to our technology or that others will not design
around the patents we own. All of our operating system software is copyrighted
and subject to the protection of applicable copyright laws. Despite our efforts
to protect our proprietary rights, unauthorized parties may attempt to copy
aspects of our products or obtain and use information that we regard as
proprietary.

 
INTELLECTUAL PROPERTY OR PRODUCT LIABILITY CLAIMS AGAINST US COULD HARM OUR
COMPETITIVE POSITION, RESULTS OF OPERATIONS AND FINANCIAL CONDITION.
 

We are aware of one third-party patent issued several years ago that may relate
to certain of our products. Although we have received no notice alleging
infringement from this third party to date, there can be no assurance that such
third party will not assert an infringement claim against us in the future.
Other than this patent, we do not believe that any of our products infringe upon
the proprietary rights of any third parties. We cannot assure you, however, that
third parties will not claim that we have infringed upon their intellectual
property rights with respect to current or future products. We expect that
developers of pharmacy and supply systems will be increasingly subject to
infringement claims as the number of products and competitors in our industry
grows and the functionality of products in different industry segments overlaps.
We do not possess special insurance that covers intellectual property
infringement claims; however, such claims may be covered under our traditional
insurance policies. These policies contain terms, conditions and exclusions that
make recovery for intellectual infringement claims difficult to guarantee. Any
infringement claims, with or without merit, could be time-consuming to defend,
result in costly litigation, divert management's attention and

 
                                       10
<Page>

resources, cause product shipment delays or require us to enter into royalty or
licensing agreements. These royalty or licensing agreements, if required, may
not be available on terms acceptable to us, or at all, which could harm our
competitive position, results of operations and financial condition.

 
We provide products that build clinical infrastructure and automate workflow.
Despite the presence of healthcare professionals as intermediaries between our
products and patients, if our products fail to provide accurate and timely
information or operate as designed, customers, patients or their family members
could assert claims against us for product liability. Also, in the event that
any of our products is defective, we may be required to recall or redesign such
products. Litigation with respect to liability claims, regardless of its
outcome, could result in substantial cost to us, divert management's attention
from operations and decrease market acceptance of our products. Although we have
not experienced any product liability claims to date, the sale and support of
our products entail the risk of product liability claims. We possess a variety
of insurance policies that include coverage for general commercial liability and
technology errors and omissions liability. However, these policies may not be
adequate against product liability claims. A successful claim brought against
us, or any claim or product recall that results in negative publicity about us,
could harm our competitive position, results of operations and financial
condition.
 
CHANGING CUSTOMER REQUIREMENTS COULD DECREASE THE DEMAND FOR OUR PRODUCTS AND
SERVICES.
 
The clinical infrastructure and workflow automation market is intensely
competitive and is characterized by evolving technologies and industry
standards, frequent new product introductions and dynamic customer requirements
that may render existing products obsolete or less competitive. As a result, our
position in the clinical infrastructure and workflow automation market could
erode rapidly due to unforeseen changes in the features and functions of
competing products, as well as the pricing models for such products. Our future
success will depend in part upon our ability to enhance our existing products
and services and to develop and introduce new products and services to meet
changing customer requirements. The process of developing products and services
such as those we offer is extremely complex and is expected to become
increasingly complex and expensive in the future as new technologies are
introduced. If we are unable to enhance our existing products or develop new
products to meet changing customer requirements, demand for our products could
decrease.
 
WE MAY BE REQUIRED TO SEEK ADDITIONAL FINANCING TO MEET OUR FUTURE CAPITAL
NEEDS, WHICH WE MAY NOT BE ABLE TO SECURE ON FAVORABLE TERMS, OR AT ALL.
 
We plan to continue to expend substantial funds for research and development
activities, product development, integration efforts and expansion of accounts
receivable and sales and marketing activities. We may be required to expend
greater than anticipated funds if unforeseen difficulties arise in the course of
completing the development and marketing of our products or services or in other
aspects of our business. One customer accounted for 11.0% of accounts receivable
at December 31, 1999. A different customer accounted for 11.0% of accounts
receivable at December 31, 2000. Our future liquidity and capital requirements
will depend upon numerous factors, including:
 
    - the development of new products and services on a timely basis;
 
    - the receipt of and timing of orders for our pharmacy and supply systems;
 
    - the cost of developing increased manufacturing and sales capacity; and
 
    - the timely collection of accounts receivable.
 
As a result of the foregoing factors, it is possible that we will be required to
raise additional funds through public or private financings, collaborative
relationships or other arrangements. We cannot assure you that this additional
funding, if needed, will be available on terms attractive to us, if at all.
Furthermore, any additional equity financing may be dilutive to stockholders,
and debt financing, if
 
                                       11
<Page>
available, may involve restrictive covenants that could affect our ability to
pay dividends or raise additional capital. Our failure to raise capital when
needed could harm our competitive position, results of operations and financial
condition.
 
GOVERNMENT REGULATION OF THE HEALTHCARE INDUSTRY COULD ADVERSELY AFFECT DEMAND
FOR OUR PRODUCTS.
 
While the manufacture and sale of our current products are not regulated by the
United States Food and Drug Administration (FDA), we cannot assure you that
these products, or our future products, if any, will not be regulated in the
future. A requirement for FDA approval could have a material adverse effect on
the demand for our products. Pharmacies are regulated by individual state boards
of pharmacy that issue rules for pharmacy licensure in their respective
jurisdictions. State boards of pharmacy do not license or approve our pharmacy
and supply systems; however, pharmacies using our equipment are subject to state
board approval. The failure of such pharmacies to meet differing requirements
from a significant number of state boards of pharmacy could decrease demand for
our products and harm our competitive position, results of operations and
financial condition. Similarly, hospitals must be accredited by the Joint
Commission on Accreditation of Healthcare Organizations (JCAHO) in order to be
eligible for Medicaid and Medicare funds. The JCAHO does not approve or accredit
pharmacy and supply systems; however, disapproval of our customers' pharmacy and
supply management methods and their failure to meet the JCAHO requirements could
decrease demand for our products and harm our competitive position, results of
operations and financial condition.
 
While we have implemented a Privacy and Use of Information Policy and strictly
adhere to established privacy principles, use of customer information guidelines
and federal and state statutes and regulations regarding privacy and
confidentiality, we cannot assure you that we will be in compliance with the
Health Insurance Portability and Accountability Act of 1996 (HIPAA). This
legislation requires the Secretary of Health and Human Services (HHS), to adopt
national standards for some types of electronic health information transactions
and the data elements used in those transactions, adopt standards to ensure the
integrity and confidentiality of health information and establish a schedule for
implementing national health data privacy legislation or regulations. In
December 2000, HHS published its final health data privacy regulations, which
will take effect in December 2002. These regulations restrict the use and
disclosure of personally identifiable health information without the prior
informed consent of the patient. HHS has not yet issued final rules on most of
the other topics under HIPAA and has yet to issue proposed rules on some topics.
The final rules, if and when issued, may differ from the proposed rules. We
cannot predict the potential impact of rules that have not yet been proposed or
any other rules that might be finally adopted instead of the proposed rules. In
addition, other federal and/or state privacy legislation may be enacted at any
time. These laws or regulations, if adopted, could restrict the ability of our
customers to obtain, use or disseminate patient information. This could
adversely affect demand for our products or force us to redesign our products in
order to meet the requirements of any new regulations.
 
OUR FACILITIES ARE LOCATED NEAR KNOWN EARTHQUAKE FAULT ZONES, AND THE OCCURRENCE
OF AN EARTHQUAKE OR OTHER NATURAL DISASTER COULD CAUSE DAMAGE TO OUR FACILITIES
AND EQUIPMENT, WHICH COULD REQUIRE US TO CEASE OR CURTAIL OPERATIONS.
 
Our facilities are located near known earthquake fault zones and are vulnerable
to significant damage from earthquakes. We are also vulnerable to damage from
other types of disasters, including tornadoes, fires, floods, power loss,
communications failures and similar events. If any disaster were to occur, our
ability to operate our business at our facilities would be seriously, or
potentially completely, impaired or destroyed. The insurance we maintain may not
be adequate to cover our losses resulting from disasters or other business
interruptions.
 
                                       12
<Page>
WE RELY ON A CONTINUOUS POWER SUPPLY TO CONDUCT OUR OPERATIONS, AND CALIFORNIA'S
CURRENT ENERGY CRISIS COULD DISRUPT OUR OPERATIONS AND INCREASE OUR EXPENSES.
 
California is in the midst of an energy crisis that could disrupt our operations
and increase our expenses. In the event of an acute power shortage, that is,
when power reserves for the State of California fall below 1.5%, California has
on some occasions implemented, and may in the future continue to implement,
rolling blackouts throughout the state. We currently do not have backup
generators or alternative sources of power in the event of a blackout, and our
current insurance does not provide coverage for any damages we or our vendors
may suffer as a result of any interruption in our power supply. If blackouts
interrupt our power supply, we would be temporarily unable to continue
operations at our facilities. Any such interruption in our ability to continue
operations at our facilities could damage our reputation, harm our ability to
retain existing customers and to obtain new customers, and could result in lost
revenue, any of which could substantially harm our business and results of
operations.
 
RISKS RELATED TO THIS OFFERING
 
OUR STOCK PRICE MAY BE EXTREMELY VOLATILE AND YOU MAY NOT BE ABLE TO RESELL YOUR
SHARES AT OR ABOVE THE INITIAL PUBLIC OFFERING PRICE.
 
Prior to the offering, there has been no public market for our common stock. We
do not know the extent to which investor interest will lead to the development
of an active public market. The initial public offering price will be determined
by negotiations between the representatives of the underwriters and us and may
not be indicative of the market price for our common stock after the offering.
With the current uncertainty about healthcare reimbursement and coverage in the
United States, there has been significant volatility in the market price and
trading volume of securities of healthcare related companies unrelated to the
performance of these companies. These broad market fluctuations may negatively
affect the market price of our common stock. As a consequence, you may not be
able to sell the common stock you purchase at or above the initial public
offering price.
 
In the past, securities class action litigation has often been brought against
companies following periods of volatility in the market price of their
securities. If brought against us, regardless of the outcome, litigation could
result in substantial costs and a diversion of our management's attention and
resources and could harm our business.
 
IF WE FAIL TO MEET THE EXPECTATIONS OF PUBLIC MARKET ANALYSTS AND INVESTORS, THE
MARKET PRICE OF OUR COMMON STOCK MAY DECREASE SIGNIFICANTLY.
 
We may fail to meet the revenue and profitability expectations of public market
analysts and investors. If this occurs, the price of our common stock will
likely fall.
 
AFTER THIS OFFERING, OUR OFFICERS, DIRECTORS AND FIVE PERCENT STOCKHOLDERS WILL
OWN A LARGE PERCENTAGE OF OUR COMMON STOCK AND WILL BE ABLE TO CONTROL THE
OUTCOME OF MATTERS REQUIRING STOCKHOLDER APPROVAL.
 
Upon the completion of this offering, executive officers, directors and current
holders of five percent (5%) or more of our outstanding common stock will, in
the aggregate, beneficially own approximately 49.1% of our outstanding common
stock. As a result, these stockholders will be able to effectively control all
matters requiring approval of our stockholders, including the election of
directors and approval of significant corporate transactions. This concentration
of ownership may also delay, deter or prevent a change in control and may make
some transactions more difficult or impossible to complete without the support
of these stockholders, even if the transaction is favorable to our stockholders.
In addition, because of their ownership of our common stock, these stockholders
will be in a position to
 
                                       13
<Page>
significantly affect our corporate actions in a manner that could conflict with
the interests of our public stockholders.
 
SUBSTANTIAL SALES OF COMMON STOCK BY OUR EXISTING STOCKHOLDERS COULD CAUSE OUR
STOCK PRICE TO FALL.
 
The market price of our common stock could decline if our existing stockholders
sell substantial amounts of our common stock in the public market after this
offering. These sales also might make it more difficult for us to sell equity
securities in the future at a time and at a price that we deem appropriate. Upon
completion of this offering, assuming the number of outstanding shares as of
June 30, 2001, we will have 20,678,920 shares of common stock outstanding,
21,578,920 shares if the underwriters exercise their over-allotment option in
full. Of these shares, 6,042,500 shares, plus an additional 900,000 shares if
the underwriters exercise their over-allotment option in full, will be freely
tradeable without restriction or further registration under the Securities Act
of 1933, as amended. Of the remaining shares, a total of approximately
14,636,420 shares held by our directors, executive officers and our existing
stockholders are subject to lock-up agreements providing that these stockholders
will not sell or otherwise dispose of any of their shares for a period of 180
days following the date of the final prospectus for this offering without the
prior written consent of U.S. Bancorp Piper Jaffray Inc. U.S. Bancorp Piper
Jaffray can release these lock-up agreements at any time. In addition, options
to purchase 3,733,997 shares of our common stock are outstanding as of June 30,
2001, under our 1992 Equity Incentive Plan, our 1995 Management Stock Option
Plan and our 1999 Equity Incentive Plan. Following this offering, we expect to
register the shares underlying these options. Subject to the exercise of these
options, shares included in such registration will be available for sale in the
open market immediately after the 180-day lock-up period expires. See "Shares
Eligible For Future Sale" for a more detailed discussion.
 
After this offering, the holders of approximately 11,375,458 shares of common
stock will be entitled to rights with respect to registration of such shares
under the Securities Act. If such holders, by exercising their registration
rights, cause a large number of securities to be registered and sold in the
public market, these sales could have an adverse effect on the market price for
our common stock. If we were to initiate a registration and include shares held
by these holders pursuant to the exercise of their registration rights, these
sales may impair our ability to raise capital.
 
OUR CERTIFICATE OF INCORPORATION AND BYLAWS CONTAIN PROVISIONS THAT COULD DELAY
OR PREVENT A CHANGE IN CONTROL THAT MAY BE FAVORABLE TO OUR STOCKHOLDERS.
 
Upon the completion of this offering, we will be subject to the Delaware
anti-takeover laws regulating corporate takeovers. These laws prevent Delaware
corporations from engaging in a merger or sale of more than 10% of their assets
with any stockholder who owns 15% or more of the corporation's outstanding
voting stock, including all affiliates and associates of any stockholder, for
three years following the date that such stockholder acquired 15% or more of the
corporation's voting stock unless:
 
    - prior to such date, the board of directors of the corporation approved
      either the business combination or the transaction that resulted in the
      stockholder becoming an interested stockholder;
 
    - upon consummation of the transaction that resulted in the stockholder's
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transaction commenced, excluding those shares owned by persons who are
      directors and also officers, and employee stock plans in which employee
      participants do not have the right to determine confidentially whether
      shares held subject to the plan will be tendered in a tender or exchange
      offer; or
 
    - on or subsequent to such date, the business combination is approved by the
      board of directors and authorized at an annual or special meeting of
      stockholders, and not by written consent, by
 
                                       14
<Page>
      the affirmative vote of at least two-thirds of the outstanding voting
      stock that is not owned by the interested stockholder.
 
As such, these laws could prohibit or delay mergers or a change of control of us
and may discourage attempts by other companies to acquire us.
 
In addition, our Certificate of Incorporation and Bylaws include a number of
provisions that may deter or impede hostile takeovers or changes of control or
management. These provisions include:
 
    - a Board of Directors classified into three classes of directors with
      staggered three-year terms;
 
    - the authority of the Board of Directors to issue up to 5,000,000 shares of
      preferred stock and to determine the price, rights, preferences and
      privileges of these shares, without stockholder approval; and
 
    - all stockholder actions must be effected at a duly called meeting of
      stockholders and not by written consent.
 
YOU WILL INCUR IMMEDIATE AND SUBSTANTIAL DILUTION OF YOUR SHARES.
 

The initial public offering price is substantially higher than the pro forma net
tangible book value of each outstanding share of our common stock. As a result,
investors participating in this offering will suffer immediate and substantial
dilution. The dilution will be $7.17 per share in the pro forma net tangible
book value of the common stock, as of March 31, 2001, from the assumed initial
public offering price of $8.00 (or $6.89 per share if the underwriters' option
to purchase additional shares is exercised in full). This dilution is described
in greater detail under "Dilution" in this prospectus. If outstanding options or
warrants to purchase shares of common stock are exercised, there will be further
dilution.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
This prospectus contains forward-looking statements. These statements relate to
future events or our future financial performance. We have attempted to identify
forward-looking statements by terminology including, "anticipates," "believes,"
"can," "continue," "could," "estimates," "expects," "intends," "may," "plans,"
"potential," "predicts," "should" or "will" or the negative of these terms or
other comparable terminology. These statements are only predictions and involve
known and unknown risks, uncertainties and other factors, including the risks
outlined under "Risk Factors," that may cause our or our industry's actual
results, levels of activity, performance or achievements to be materially
different from any future results, levels of activity, performance or
achievements expressed or implied by these forward-looking statements.
 
Although we believe that our expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. We are not under any duty to update any
of the forward-looking statements after the date of this prospectus to conform
these statements to actual results, unless required by law.
 

                                USE OF PROCEEDS
 
We estimate that our net proceeds from the sale of the 6,000,000 shares of
common stock we are offering, assuming an initial public offering price of $8.00
per share, will be approximately $43,040,000, or $49,736,000 if the
underwriters' over-allotment option is exercised in full, after deducting the
estimated underwriting discounts and commissions and estimated offering expenses
payable by us.
 
Although we have not yet formulated a specific plan, we currently intend to use
a significant portion of the net proceeds for the expansion of sales, marketing,
research and development and customer support activities. We also intend to use
approximately $7.9 million of the net proceeds to repay the outstanding
principal and interest related to the note held by Baxter Healthcare incurred in
connection with our acquisition of the Sure-Med product line in January 1999.
The Baxter Healthcare note accrues interest at a rate of 8.0%. In addition, the
principal under the note is repayable in eight equal quarterly installments
beginning in March 2002. We also intend to use approximately $10.4 million of
the net proceeds to redeem 720,800 shares of redeemable convertible preferred
stock plus accrued interest thereon held by Sun Healthcare at the closing of
this offering.
 
We expect to use the remainder of the net proceeds for working capital and other
general corporate purposes, including potential acquisitions and costs to
support our leasing activities to U.S. government entities. We currently have no
commitments or agreements and are not involved in any negotiations for
acquisitions of complementary products, technologies or businesses.
 
The amounts that we actually expend on these matters will vary significantly,
depending on a number of factors, including future revenue growth, if any, and
the amount of cash we generate from operations. As a result, we will retain
broad discretion in the allocation of the net proceeds of this offering. Pending
use of the net proceeds of this offering, we intend to invest the net proceeds
in interest bearing, investment-grade securities.
 

                                DIVIDEND POLICY
 
We currently intend to retain future earnings, if any, to finance the expansion
of our business and do not anticipate paying any cash dividends on our common
stock in the foreseeable future. The terms of our line of credit prohibit the
payment of cash dividends on our capital stock without the consent of our
lender.

                                 CAPITALIZATION
 
The table below presents the following information:
 
    - our actual capitalization as of March 31, 2001; and
 
    - our pro forma as adjusted capitalization as of March 31, 2001 after giving
      effect to (i) the redemption of 720,800 shares of our redeemable
      convertible preferred stock and (ii) the conversion of all of our
      convertible preferred stock and a convertible note into shares of our
      common stock upon completion of this offering and to reflect the receipt
      and application of the net proceeds from our sale of 6,000,000 shares of
      common stock at an assumed initial public offering price of $8.00 per
      share in this offering, less underwriting discounts and commissions and
      estimated offering expenses payable by us as discussed in "Use of
      Proceeds."
 
You should read this table in conjunction with the financial statements and the
other financial information included in this prospectus.

                                    DILUTION
 

Our pro forma net tangible book value (deficiency) as of March 31, 2001, was
approximately $(26.0) million, or $(1.80) per share. Pro forma net tangible book
value (deficiency) per share represents the amount of pro forma stockholders'
equity (or net capital deficiency), assuming (i) the redemption of
720,800 shares of our redeemable convertible preferred stock and (ii) the
conversion of all of our convertible preferred stock and a convertible note into
common stock, less intangible assets, divided by the pro forma number of shares
of common stock outstanding as of March 31, 2001. Dilution per share represents
the difference between the amount per share paid by purchasers of shares of
common stock in this offering and the pro forma net tangible book value per
share of common stock immediately after completion of this offering.

 

Pro forma net tangible book value as of March 31, 2001, after giving effect to
the sale of 6,000,000 shares of common stock offered by us at an initial public
offering price of $8.00 per share and after deducting underwriting discounts and
commissions and estimated offering expenses payable by us, would have been
approximately $17.0 million, or approximately $0.83 per share. This represents
an immediate increase in pro forma net tangible book value of $2.63 per share to
existing stockholders and an immediate dilution in pro forma net tangible book
value of $7.17 per share to investors purchasing our common stock in this
offering, as illustrated in the following table:

If the underwriters exercise their over-allotment in full, the following will
occur:
 
    - the number of shares of common stock held by existing stockholders will
      decrease to approximately 68% of the total number of shares of our common
      stock outstanding; and
 
    - the number of shares held by new investors will increase to 6,900,000
      shares, or approximately 32% of the total number of shares of common stock

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
To aid you in your analysis, we are providing the following information. We
derived the selected consolidated statement of operations data for the years
ended December 31, 1998, 1999 and 2000 and the consolidated balance sheet data
as of December 31, 1999 and 2000 from our audited consolidated financial
statements included elsewhere in this prospectus. The selected consolidated
statement of operations data for the years ended December 31, 1996 and 1997 and
the consolidated balance sheet data as of December 31, 1996, 1997 and 1998 are
derived from audited consolidated financial statements not included in this
prospectus. The consolidated statement of operations data set forth below for
the three months ended March 31, 2000 and 2001 and the consolidated balance
sheet data as of March 31, 2001 are derived from our unaudited consolidated
financial statements included elsewhere in this prospectus, which have been
prepared on the same basis as the audited consolidated financial statement and,
in our opinion, fairly present the information set forth therein. The pro forma
net loss per common share and shares used in computing pro forma net loss per
share are calculated as if (i) redemption of 720,800 shares of our redeemable
convertible preferred stock and (ii) conversion of all of our convertible
preferred stock and a convertible note into shares of our common stock occur on
the date of their issuance. The other data, although not derived from our
financial statements, was derived from a customer information database. When you
read this selected consolidated financial data, it is important that you also
read the historical consolidated financial statements and related Notes included
in this prospectus, as well as the section of this prospectus entitled
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

PROSPECTUS.
 
OVERVIEW
 
We were formed in 1992 and began offering our supply systems for sale in 1993.
In late 1996, we introduced our Omnicell pharmacy system. In January 1999, we
expanded our line of pharmacy systems and customer base with the acquisition of
the Sure-Med product line from Baxter Healthcare. As of March 31, 2001, we had
installed over 18,600 of our pharmacy and supply systems in over 1,100
healthcare facilities.
 
We sell our pharmacy and supply systems primarily in the United States. We have
a direct sales force organized into six regions in the United States and Canada.
We sell through distributors in Europe, the Middle East, Asia and Australia. We
manufacture the majority of our systems in our production facility in Palo Alto,
California, with refurbishment and spare parts activities conducted in our
Waukegan, Illinois facility.
 
Sun Healthcare, a formerly related party, was previously a significant customer
of ours, representing 19.7% of our total revenues in 1997, 20.5% in 1998, 9.3%
in 1999 and 2.7% in 2000. Sun Healthcare filed for Chapter 11 bankruptcy
protection in the third quarter of 1999. We do not anticipate any significant
revenue from Sun Healthcare in 2001 or in future years.
 
REVENUES
 
Customers acquire our pharmacy and supply systems either through an outright
purchase or a non-cancelable long-term lease, which typically has a term of
60 months. We bill our customers upon delivery and acceptance of our pharmacy
and supply systems and recognize revenue when the systems are installed.
Generally, we try to install our pharmacy and supply systems within three to six
months after shipment, but installation, at the customer's request, can be
delayed for a year or more. Some customers experience delays in installation due
to site construction and delays in receiving interfaces from third parties.
 
Typically, we will sell our customer lease agreements on a non-recourse basis to
third-party leasing companies. Lease revenue is recognized in the amount funded
by the leasing company. As part of the initial sale of our pharmacy and supply
systems, customers typically sign a one-year service agreement, and service
revenues are recognized over the term of these agreements. Service and other
revenues also include month to month rentals of our pharmacy and supply systems,
amortization of upfront fees received from certain distributors of our pharmacy
and supply systems and monthly subscription fees from hospitals utilizing our
Internet-based procurement application.
 
Deferred gross profit on our balance sheet represents pharmacy and supply
systems that have been shipped to, accepted, and, in most instances, paid for by
our customers but not yet installed at the customer site. We record these
shipments as deferred gross profit because title to the inventory has passed to
the customer. Deferred gross profit is not equal to gross margin because it does
not include installation costs, which are incurred and recorded in the period
when revenue is recognized. Our installation process typically takes a week or
less to complete.
 
                                       21

Revenues from our pharmacy and supply systems are difficult to forecast because
the sales cycle, from initial assessment to product installation, involves a
significant commitment of capital and time, varies substantially from customer
to customer and can take more than one year. The order approval process of our
customers is subject to internal procedures associated with large capital
expenditures and the time associated with accepting new technologies. For these
and other reasons, the sales cycle associated with the purchase of our pharmacy
and supply systems is typically lengthy and subject to a number of significant
risks, including customers' budgetary constraints and internal acceptance
reviews over which we have little or no control.
 
In part due to our acquisition of the Sure-Med product line from Baxter
Healthcare, sales of pharmacy systems have grown, in dollar terms, from 23% of
our product shipments in 1997 to 40% in 2000. As of March 31, 2001, we had
generated only minimal revenues from subscription fees for our OmniBuyer
application.
 
COSTS AND EXPENSES
 
Our current expense levels are based, in part, on our expectations of higher
future revenue levels. If revenue levels are below expectations, operating
results are likely to be disproportionately impacted given our significant
investment in infrastructure. We have never achieved profitability on an annual
operating basis, and our current revenues and gross profit are not sufficient to
support our operating expenses. Based on the foregoing, we believe that period
to period comparisons of our results of operations are not necessarily
meaningful and should not be relied upon as indications of future performance.
 
Cost of product revenues consists primarily of direct materials, labor and
overhead required to manufacture pharmacy and supply systems and also includes
costs required to install our systems at the customer location. Costs of service
and other revenue include spare parts required to maintain and support installed
systems and service and maintenance expense, including outsourced contract
services. Direct materials and installation costs are mostly variable.
Manufacturing labor and overhead remain relatively fixed over ranges of
production volume. The cost of service and spare parts has increased as the size
of our installed base of customers increases.
 
Our research and development expenses include engineering and development
salaries, wages and benefits, prototyping and laboratory expenses, consulting
expenses and engineering-related facilities and overhead charges. Most of the
research and development expenses are personnel- or facilities-related and are
relatively fixed. Prototyping and consulting expenses will vary depending on the
stage of completion of various engineering and development projects.
 
Our selling, general and administrative expenses include costs to support the
sales, marketing, field operations and customer support and administration
organizations. Most of these costs are personnel- or facilities-related and are
relatively fixed. Bonuses and sales commissions will typically change in
proportion to revenue or profitability. Other expenditures, such as advertising,
promotions and consulting, are neither fixed nor variable and will fluctuate
depending on product introductions, promotional programs and trade shows.
 
We recorded deferred stock compensation with respect to options granted to
employees of approximately $2.6 million in the year ended December 31, 2000 and
$136,000 in the three months ended March 31, 2001, representing the difference
between the deemed fair value of our common stock for financial reporting
purposes on the date these options were granted and the exercise price. These
amounts have been reflected as components of stockholders' equity (net capital
deficiency) and the deferred expense is being amortized to operations over the
two to four year vesting periods of the options using the graded vesting method.
We amortized deferred stock compensation of $816,000 in 2000, with $38,000
attributable to cost of revenues, $139,000 related to research and development
and $639,000 attributable to selling, general and administrative efforts. In the
three months ended
 
                                       22
<Page>
March 31, 2001, we amortized deferred stock compensation of $428,000, with
$20,000, $73,000 and $335,000 related to cost of revenues, research and
development expense and selling, general and administrative expense,
respectively. At March 31, 2001, we had approximately $1.5 million remaining to
be amortized over the vesting periods of the stock options. For the year ending
December 31, 2001, the total amortization of deferred stock compensation is
expected to be approximately $1.25 million. We also expect to record deferred
stock compensation for options granted from April 1, 2001 through June 30, 2001.
Our policy is to use the graded vesting method for recognizing compensation
costs for fixed awards with pro rata vesting. The graded vesting method provides
for vesting of portions of the overall awards at interim dates and results in
greater vesting in earlier years than the straightline method.
 
Due to relatively low demand for our Internet-based procurement application,
OmniBuyer, we restructured our e-commerce business in the third quarter of 2000
and reduced operating expenses. In particular, we decreased the number of
employees in this area and lowered our spending on sales, marketing and research
and development. We decided not to pursue an exchange based on the Commerce One
MarketSite license and refocused on marketing OmniBuyer to our hospital and
alternate care customers. As part of this restructuring, we recorded a charge of
$2.9 million, comprised of a $2.0 million writedown of our Commerce One
MarketSite license, $0.6 million in employee severance-related expenses and a
$0.3 million writedown of previously capitalized software.

THREE MONTHS ENDED MARCH 31, 2001 AND 2000
 
REVENUES.  Total revenues increased 31.1% from $14.5 million for the three
months ended March 31, 2000 to $19.0 million for the three months ended
March 31, 2001. Product revenues increased by 34.3% from $12.5 million in 2000
to $16.7 million in 2001, due primarily to an increase in the number of pharmacy
and supply systems available for installation and installed, resulting from
increased sales and shipment activities. Product revenues for the quarter ended
March 31, 2001 decreased 4.0% from the preceding quarter ended December 31,
2000. This reduction reflects delays in the completion of installation
activities for certain pharmacy and supply systems until the quarter ended
June 30, 2001. We do not consider this reduction in product revenues to be a
trend as evidenced by the $18.5 million of product revenues in the quarter ended
June 30, 2001.
 
Service and other revenues increased by 11.2% from $2.0 million for the three
months ended March 31, 2000 to $2.3 million for the three months ended
March 31, 2001. The increase in service and other revenues was primarily due to
the increase in our installed base of pharmacy and supply systems combined with
an increase in the number of month-to-month short term rentals. We anticipate
that service and other revenues will continue to grow in absolute dollars due to
continued growth in our installed base of pharmacy and supply systems.
 
Deferred gross profit of $25.3 million at March 31, 2001 remained relatively
consistent with the balance at December 31, 2000. We anticipate that deferred
gross profit will remain relatively constant with the March 31, 2001 balance due
to shipments approximating installations in future periods. Delays in
installation occur for a variety of reasons, including construction delays and
delays in receiving software from third party vendors. We recognize revenue and
reduce deferred gross profit when installation is complete.
 

COST OF REVENUES.  Cost of product revenues increased 18.3% from $4.6 million
for the three months ended March 31, 2000 to $5.4 million for the three months
ended March 31, 2001. Gross profit on product sales was $7.9 million, or 63.2%
of product revenues, in the first quarter of 2000 compared to $11.3 million, or
67.6% of product revenues, in the first quarter of 2001. The increase in gross
margin was due to an increased number of pharmacy and supply systems being
allocated a relative consistent amount of manufacturing overhead spending. We
believe this level of product gross margins is sustainable.

 
Cost of service and other revenues decreased by 17.1% from $2.1 million for the
three months ended March 31, 2000 to $1.7 million for the three months ended
March 31, 2001. For the same periods, gross margin on service and other revenues
was $(0.1) million, or (3.1)% of service and other revenues, in 2000 compared to
$0.5 million, or 23.1% of service and other revenues, in 2001. The higher level
of cost of service and other revenues for the three months ended March 31, 2000
was due to a high level of expenses for service parts and spares. Sure-Med
pharmacy systems require more costly installation kits than Omnicell automation
systems. The three month period ending March 31, 2000 had an unusually large
percentage of Sure-Med units to be installed including units which had been
shipped by Baxter Healthcare prior to January 1999. We were responsible for
installing these Sure-Med systems and for providing the required installation
kits. The unusually high level of expenses decreased throughout fiscal 2000 as
most Sure-Med systems shipped by Baxter Healthcare have been installed. The cost
of service and other revenues for the three month period ended March 31, 2001
have a lower volume of Sure-Med installation kits.
 
RESEARCH AND DEVELOPMENT.  Research and development expenses decreased 26.7%
from $3.5 million for the three months ended March 31, 2000 to $2.5 million for
the three months ended March 31, 2001. The decrease in research and development
expenses was primarily the result of decreased spending for development of the
internet-based procurement application. To date we have capitalized
$1.0 million in software development costs. We anticipate that research and
development expenses will increase modestly in absolute dollars.
 
                                       24
<Page>
SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative costs
decreased by 11.4% from $11.4 million for the three months ended March 31, 2000
to $10.1 million for the three months ended March 31, 2001. The decrease was
primarily the result of decreased spending in sales and marketing for the
internet-based procurement application, and decreases in marketing expenses for
advertising and trade shows. We anticipate that selling, general and
administrative costs will increase modestly for the remainder of 2001.
 
INTEREST INCOME (EXPENSE).  Net interest expense increased from $321,000 for the
three months ended March 31, 2000 to $586,000 for the three months ended
March 31, 2001. The increase was due primarily to increased interest expense of
approximately $190,000 and decreased earnings on lower invested cash balances.
 
YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998
 
REVENUES.  Total revenues increased 21.9% from $55.3 million for the year ended
December 31, 1999 to $67.4 million for the year ended December 31, 2000. Total
revenues increased 14.6% from $48.2 million for the year ended December 31, 1998
to $55.3 million for the year ended December 31, 1999.
 
Product revenues increased by 23.5% from $48.2 million in 1999 to $59.6 million
in 2000, due primarily to a change in our product mix to a larger proportion of
higher-priced pharmacy systems from 1999 to 2000 and an increase in the number
of pharmacy and supply systems installed from 1999 to 2000. Product revenues
increased by 9.4% from $44.1 million in 1998 to $48.2 million in 1999, due to an
increase in the number of pharmacy and supply systems installed from 1998 to
1999 partially offset by sales of a larger proportion of supply systems from
1998 to 1999. Our slower rate of product revenue growth in 1999 compared to
preceding years was due to our largest customer Sun Healthcare's financial
difficulties and by delays in purchase decisions by other customers over
concerns related to Year 2000.
 
Service and other revenues increased by 11.0% from $7.0 million in 1999 to
$7.8 million in 2000. This increase was due to a higher installed base of
systems partially offset by lower service revenue from Sun Healthcare. Under the
terms of the Sure-Med acquisition, we assumed from Baxter Healthcare the
remaining service obligations to certain Sure-Med lease customers, but we do not
receive any service revenue associated with such obligations. Service and other
revenues increased by 70.6% from $4.1 million in 1998 to $7.0 million in 1999.
The increase in service and other revenues in 1999 was due primarily to the
increase in our installed base of pharmacy and supply systems. We anticipate
that service and other revenues will continue to grow in dollar terms and as a
percentage of our total revenues due to continued growth in our installed base
of pharmacy and supply systems.
 

Deferred gross profit decreased by 3.2% from $26.7 million at December 31, 1999
to $25.8 million at December 31, 2000. This decrease was due to higher cost of
sales in the deferred gross profit balance at December 31, 2000 compared to the
cost of sales in the deferred gross profit balance at December  31, 1999. This
was due to an increased mix of higher margin pharmacy and supply systems
installed in 2000 compared to the pharmacy and supply systems shipped in 2000.
We do not believe this reduction to be indicative of future decreases in gross
profit as our increased shipment activity will enable us to leverage our fixed
base of manufacturing and service infrastructure to achieve higher gross
profits. Deferred gross profit increased by 32.0% from $20.2 million at
December 31, 1998 to $26.7 million at December 31, 1999 due to significantly
more shipments of pharmacy and supply systems than installations during 1999.

 

COST OF REVENUES.  Cost of product revenues decreased by 34.8% from
$28.9 million in 1999 to $18.9 million in 2000. Gross profit on product revenues
was $19.3 million, or 40.1% of product revenues in 1999, compared to
$40.7 million, or 68.3% of product revenues in 2000. The 2000 decrease in cost
of product revenues and increase in gross profit percentage were due primarily
to a $9.7 million writedown of Sure-Med inventory in the fourth quarter of 1999
because of lower than anticipated

 
                                       25
<Page>

demand for Sure-Med pharmacy systems. Subsequent to the January 1999 acquisition
of the Sure-Med product line, product integration issues related to the Sure-Med
acquisition slowed our sales force's ability to effectively sell the Sure-Med
pharmacy systems. Cost of product revenues in 2000 was also favorably impacted
as the mix of less costly Omnicell systems sold increased from 71.8% to 82.0%,
an increase in the number of sales versus leased transactions for which gross
margins are higher, and a smaller component of manufacturing overhead allocated
to each system as production volumes increased. This 2000 reduction in cost of
product revenues was partially offset by a $2.2 million increase to our
estimated liability to provide certain specific functionality to Sure-Med
products. This increase resulted from the identification of additional Sure-Med
customers who had contractual rights to the specified functionality and a higher
than originally estimated materials, labor and shipping costs to fulfill each
obligation.

 
Cost of product revenues increased by 76.9% from $16.3 million in 1998 to
$28.9 million in 1999. Gross profit on product revenues was $27.7 million, or
62.9% of product revenues in 1998 compared to $19.3 million, or 40.1% of product
revenues in 1999. The 1999 increase in cost of product revenues was due
primarily to the writedown of Sure-Med inventory. Cost of product revenues and
gross profit on product revenues in 1999 were also adversely affected by the
minimal gross profit recorded on sales of Sure-Med inventories that had been
written up to fair value upon the acquisition.
 
Excluding the impact of the Sure-Med inventory and other writedowns, cost of
product revenues increased to $19.2 million for 1999 compared to $16.3 million
in 1998, reflecting an increase in the number of systems installed and higher
manufacturing costs per unit. As a percent of product revenues, cost of product
revenues, excluding the impact of the Sure-Med inventory and other writedowns,
increased from 37.1% in 1998 to 39.8% in 1999.
 
Cost of service and other revenues increased by 43.6% from $5.4 million in 1999
to $7.7 million in 2000. For the same periods, gross profit on service and other
revenues was $1.7 million, or 23.6% of service and other revenues in 1999
compared to $0.1 million, or 1.1% of service and other revenues in 2000. The
decline in gross profit on service and other revenue in 2000 compared to 1999
was due to service and maintenance costs on Sure-Med units sold prior to the
acquisition, for which we did not receive revenue, being significantly higher
than our original estimates reflected in the purchase price allocation. Cost of
service and other revenues increased by 198.6% from $1.8 million in 1998 to
$5.4 million in 1999. For the same periods, gross profit on service and other
revenues was $2.3 million, or 56.3% of service and other revenues in 1998
compared to $1.7 million or 23.6% of service and other revenues in 1999. The
lower gross profit on service and other revenues in 1999 compared to 1998 was
due primarily to the acquisition of the Sure-Med product line and the higher
level of service required for the Sure-Med pharmacy systems.
 
RESEARCH AND DEVELOPMENT.  Research and development expenses increased by 28.9%
from $8.7 million in 1999 to $11.3 million in 2000. Research and development
expenses represented 15.8% and 16.7% of total revenues in 1999 and 2000,
respectively. The increase in research and development expenses was primarily
attributable to higher costs associated with additional engineering for
enhancements to our pharmacy systems and for customization of Commerce One's
technology for OmniBuyer customers. We anticipate that we will continue to
commit significant resources to research and development in future periods to
enhance and extend our pharmacy and supply systems. We expect that research and
development expenses will increase in overall dollars, but not as a percentage
of total revenues from current levels. To date, we have capitalized
approximately $0.9 million of software development costs in 2000 for our
pharmacy and supply systems.
 
Research and development expenses increased by 46.1% from $6.0 million in 1998
to $8.7 million in 1999. Research and development expenses represented 12.4% and
15.8% of total revenues in 1998 and 1999, respectively. The increase in research
and development expenses was primarily attributable to
 
                                       26
<Page>
higher costs associated with additional engineering personnel retained as part
of the acquisition of the Sure-Med product line from Baxter Healthcare.
 
SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative costs
increased by 26.7% from $35.8 million in 1999 to $45.3 million in 2000. Selling,
general and administrative expenses represented 64.8% and 67.3% of total
revenues in 1999 and 2000, respectively. The increase in selling, general and
administrative expenses is due primarily to staffing increases associated with
the introduction of OmniBuyer and supporting the growth of our pharmacy and
supply system business. In addition, we wrote off approximately $1.1 million in
previously capitalized offering expenses. We anticipate that we will continue to
commit significant resources to our sales, customer support, marketing, finance
and administration organizations. We expect that selling, general and
administrative expenses will continue to increase in dollar terms. However, we
do not anticipate that selling, general and administrative expenses will
increase significantly, if at all, as a percentage of total revenues.
 
Selling, general and administrative costs increased by 47.4% from $24.3 million
in 1998 to $35.8 million in 1999. Selling, general and administrative expenses
represented 50.4% and 64.8% of total revenues in 1998 and 1999, respectively.
The increase in selling, general and administrative expenses is due to staffing
increases necessary to manage and support our growth in revenues, as well as
increased staffing as a result of the acquisition of the Sure-Med product line
from Baxter Healthcare. Also included in selling, general and administrative
costs in 1999 is $0.6 million relating to the write-off of an equity investment.
 
INTEGRATION.  Integration expenses of $0.8 million in 1999 consist of costs
associated with the integration of Omnicell and Sure-Med engineering efforts,
product lines and marketing efforts.
 
RESTRUCTURING.  Restructuring charges in 2000 of $2.9 million include the
$2.0 million write-off of the Commerce One MarketSite license, $0.3 million
write-off of capitalized software development costs and $0.6 million in employee
severance and related expenses.
 
INTEREST INCOME (EXPENSE).  Net interest expense was $1.8 million in 1999
compared to net interest expense of $1.2 million in 2000. The lower net interest
expense was primarily due to an increase in interest income from employee loans
in 2000 as well as higher average cash balances than in 1999 and a reduction in
interest paid to Sun Healthcare due to lower average outstanding balances of
redeemable preferred stock. Net interest income was $1.0 million in 1998
compared to net interest expense of $1.8 million in 1999, reflecting a reduction
in interest income due to a decrease in cash, cash equivalents and short-term
investment balances and an increase in interest expense due to debt obligations
incurred as part of the Sure-Med acquisition, as well as interest paid to Sun
Healthcare for redemption of its redeemable preferred stock.
 
QUARTERLY RESULTS OF OPERATIONS
 
In any given quarter, it is common for a few customers to make up a substantial
percentage of our pharmacy and supply systems revenues, although the identity of
such customers generally varies from quarter to quarter. The timing of purchase
decisions by large hospital customers has a material impact on our deferred
gross profit position but a less significant impact on quarterly results of
operations which depend on our ability to install systems that have already been
shipped to customers. As revenues increase, gross profit should improve due to
leverage of our manufacturing and service infrastructure and reductions in
direct material costs through higher volumes of materials purchases. If revenues
are below expectations then gross profits are likely to be reduced due to our
investment in manufacturing and service infrastructure based on our internal
projections of future revenues.
 
                                       27
<Page>
Our quarterly operating results have varied significantly in the past and may
vary significantly in the future depending on many factors that may include, but
are not limited to, the following:
 
    - the size and timing of significant orders and their fulfillment and
      installation;
 
    - changes in pricing policies by us or our competitors;
 
    - the number, timing and significance of product enhancements and new
      product announcements by us or our competitors;
 
    - changes in the level of our operating expenses;
 
    - our customers' budgeting cycles; and
 
    - changes in our strategy and general domestic and international economic
      and political conditions.
 
The following tables present certain unaudited statement of operations data for
each quarter of 1999 and 2000. These data have been derived from unaudited
consolidated financial statements and have been prepared on the same basis as
our audited consolidated financial statements which appear elsewhere in this
prospectus. In the opinion of our management, these data include all
adjustments, consisting only of normal recurring adjustments and, in the fourth
quarter of 1999 and third quarter of 2000, special charges described below,
necessary for a fair presentation of such data.

    $0.6 million in employee severance expenses; and $0.3 million writedown of
    capitalized software development costs.
 
LIQUIDITY AND CAPITAL RESOURCES
 

We have financed our operations since inception primarily through the private
placement of equity securities, as well as through equipment financing and
secured loan arrangements. Through March 31, 2001, we have raised approximately
$81.0 million from the private placement of equity securities, net of
redemptions. This includes net proceeds of approximately $28.6 million from our
last equity financing in the first quarter of 2000.

 
As of March 31, 2001, our principal sources of liquidity included approximately
$7.7 million in cash, cash equivalents and short-term investments and an undrawn
$10.0 million revolving credit facility. Our funds are currently invested in
U.S. Treasury and government agency obligations, investment grade commercial
paper and short-term interest-bearing securities.
 
In connection with the acquisition of the Sure-Med product line, we incurred a
note payable to Baxter Healthcare of approximately $7.9 million. The note is
secured by substantially all of the assets supporting the Sure-Med product line.
The note is for a term of five years and is repayable in eight equal quarterly
installments beginning on March 31, 2002, or earlier upon the closing of an
initial public offering. Interest payments are due quarterly at a rate of 8.0%
through December 31, 2001, 9% through December 31, 2002 and 10% through
December 31, 2003. We expect to utilize a portion of the net proceeds from this
offering to repay the Baxter Healthcare note in full.
 
We have established a credit facility with a bank that provides us with advances
of up to 80% of eligible receivables, as defined, up to $10.0 million, and
expires on June 30, 2002. Any advances under the credit facility would be
secured by substantially all of our assets. Interest under the credit agreement
is payable at an annual rate equal to our lender's prime rate plus 2.25%. Our
credit agreement contains covenants that include limitations on indebtedness and
liens, in addition to thresholds relating to net capital deficiencies that
define borrowing availability and restrictions on the payment of dividends. As
of March 31, 2001, we had no borrowings under this credit facility, were
eligible to borrow approximately $9.7 million, and were in compliance with the
covenants.
 
We used cash of $19.1 million in operating activities in 2000 compared to
$5.0 million used in operating activities in 1999 and $6.7 million provided by
operating activities in 1998. The net loss of $20.8 million for 2000 included
non-cash charges for depreciation and amortization of $2.8 million, deferred
stock compensation of $0.8 million, stock compensation of $0.7 million and a
decrease in deferred gross profit of $0.8 million. The net loss of
$26.3 million for 1999 included non-cash charges for depreciation and
amortization of $2.0 million, Sure-Med pharmacy systems inventory write-off of
$9.7 million, an investment writedown of $0.6 million, and an increase in
deferred gross profit of $6.0 million. In 1998, cash was provided by net income
of $0.6 million, a decrease in accounts receivable of $2.1 million and an
increase in deferred gross profit of $4.0 million. In the three months ended
March 31, 2001, we used $3.7 million of cash in operating activities compared to
$10.0 million in the comparable period of 2000. This reduction in use of cash in
2001 was due principally to our lower net loss. In addition, operating cash
flows benefited from a $3.8 million increase in accrued liabilities primarily
due to the receipt of $4.2 million from a customer in advance of the execution
of a final sale arrangement, partially offset by a $2.1 million increase in
inventories to support increased demand. The $4.3 million increase in accounts
receivable resulted from a significant portion of our pharmacy and supply system
product shipments occurring in March.
 
Cash of $1.4 million was provided from investing activities in 2000 compared to
cash of $0.2 million used in investing activities in 1999 and cash of
$7.3 million used in investing activities in 1998. Net maturities of short-term
investments were $1.9 million in 2000 and $6.4 million in 1999 compared to
 
                                       29
<Page>
net purchases of $5.5 million in 1998. Our 2000 expenditures for property and
equipment of $0.5 million was less than the $6.2 million expended in 1999 and
the $1.8 million expended in 1998. In the three months ended March 31, 2001, we
used $3.7 million of cash in investing activities compared to $12.9 million in
the prior year, principally due to a decrease in net purchases of short-term
investments of $11.8 million.
 
We generated cash from financing activities of $24.9 million in 2000 primarily
due to completing a private placement of $28.5 million in Series K Preferred
Stock partially offset by redemptions of redeemable preferred stock. We used
$3.8 million of cash in financing activities in 1999 due primarily to redemption
of redeemable preferred stock and $0.6 million of cash was provided by financing
activities in 1998 through the issuance of common stock. In the three months
ended March 31, 2001, we generated $44,000 of cash from financing activities
compared to $26.8 million in the prior year. The decrease is attributable to the
completion of our Series K preferred stock financing that raised $28.6 million
in the 2000 period.
 
Through March 31, 2001, we had redeemed 1,081,200 shares of Series J redeemable
convertible preferred stock from Sun Healthcare for $15.2 million plus interest
of $2.7 million. Cash of $11.6 million was used to satisfy this redemption, with
the balance paid by offsetting Sun Healthcare's outstanding accounts receivable
balances. In January 1999, Sun Healthcare exercised its right to have us redeem
its 1,802,000 shares of Series J Preferred Stock in ten equal quarterly
installments beginning in March 1999. All payments have been made except the
four quarterly redemption payments of $2.5 million each that were due in
September 2000, December 2000, March 2001 and June 2001, which we were not
obligated to make because we did not meet certain balance sheet tests under
California law. We will no longer be subject to these restrictions of California
law following our reincorporation in Delaware. We plan to redeem the balance of
the 720,800 shares of Series J Preferred Stock for approximately $10.1 million
upon the closing of this offering with a portion of the net proceeds.
 
We have not paid any significant amount of taxes to date. As of December 31,
2000, we have a net operating loss carryforward for U.S. income tax purposes of
approximately $38.0 million, expiring beginning in 2009. There are certain
limitations on the use of this net operating loss carryforward. For more
information, please see the notes to our consolidated financial statements.
 
We may be required to raise additional capital through the public equity market,
private financings, collaborative arrangements and debt. If additional capital
is raised through the issuance of equity or securities convertible into equity,
our stockholders may experience dilution, and such securities may have rights,
preferences or privileges senior to those of the holders of the common stock.
Additional financing may not be available to us on favorable terms, if at all.
If we are unable to obtain financing, or to obtain it on acceptable terms, we
may be unable to execute our business plan.
 
On March 9, 2001, we withdrew our registration statement on Form S-1
(registration no. 333-35258) that was originally filed with the SEC on
April 20, 2000.
 
QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET AND INTEREST RATE RISK
 
The following discusses our exposure to market risk related to changes in
interest rates, foreign currency exchange rates and equity prices. We reduce the
sensitivity of our results of operations to these risks by maintaining an
investment portfolio which is comprised solely of highly rated, short-term
investments. We do not hold or issue derivative, derivative commodity
instruments or other financial instruments for trading purposes. We are exposed
to currency exchange fluctuations, as we sell our products internationally. We
manage the sensitivity of our international sales by denominating all
transactions in U.S. dollars.
 
                                       30
<Page>
We are exposed to interest rate risk, as we use additional debt financing
periodically to fund capital expenditures. The interest rate that we may be able
to obtain on debt financings will depend on market conditions at that time and
may differ from the rates we have secured in the past.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
In March 2000, the Emerging Issues Task Force (EITF) published its consensus on
Issue No. 00-2, "Accounting for Web Site Development Costs." This EITF sets
forth guidance on whether to capitalize or expense certain development costs. We
have adopted EITF 00-2 effective January 1, 2000 and capitalized $260,000 of web
site development costs in the year ended December 31, 2000. These costs were
written off as a part of the 2000 restructuring activities.
 
In March, 2000, the FASB issued Interpretation No. 44, "Accounting for Certain
Transactions Involving Stock Compensation," an interpretation of APB 25. The
Interpretation is applied prospectively to all new awards, modifications to
outstanding awards, and changes in employee status after July 1, 2000, with the
exception of the definition of employee and stock option repricings as to which
the effective date is December 15, 1998. The adoption of this Interpretation did
not have a significant effect on our results of operations or financial
condition.
 
In December 1999, the Securities and Exchange Commission issued SAB No. 101,
"Revenue Recognition in Financial Statements." SAB 101 provides guidance on the
recognition, presentation and disclosure of revenue in financial statements. We
have adopted SAB 101 for all periods presented.
 
In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS 137 and 138, which is
effective for years beginning after June 15, 2000. SFAS 133, as amended, will
require us to recognize all derivatives on the balance sheet at fair value.
Gains or losses resulting from changes in the values of those derivatives would
be accounted for depending on the use of the derivative and whether it qualifies
for hedge accounting. SFAS 133 will be effective for our financial statements
for the year ended December 31, 2001. Management believes that this statement
will not have a significant effect on our results of operations or financial
condition.

                                   BUSINESS
 
OVERVIEW
 
We provide an integrated suite of clinical infrastructure and workflow
automation solutions for healthcare facilities. These solutions include pharmacy
and supply systems, clinical reference tools, an Internet-based procurement
application and decision support capabilities. We sell and lease our products
and related services to a wide range of healthcare facilities such as hospitals,
integrated delivery networks and specialty care facilities, which include
nursing homes, outpatient surgery centers, catheterization labs and clinics. As
of March 31, 2001, we had installed over 18,600 of our pharmacy and supply
systems in over 1,100 healthcare facilities in the United States. In 2000, we
generated revenue of $67.4 million from the sale and lease of our products and
related services.
 
The healthcare industry's clinical workflow processes are highly inefficient and
predominantly manual. The industry's historical reluctance to invest in
information technology has contributed to medical errors and high process costs.
Our automation solutions are designed to enable healthcare facilities to reduce
medication errors, decrease costs, enhance operating efficiency and improve
patient care.
 
Our clinical infrastructure and workflow automation solutions enable healthcare
facilities to acquire, manage, dispense and deliver pharmaceuticals and medical
supplies more effectively and efficiently. Our pharmacy and supply systems
facilitate controlled delivery of pharmaceuticals and medical supplies directly
to clinicians at the point of care. Our Internet-based procurement application
automates and integrates healthcare facilities' requisition and approval
processes. Our decision support product provides healthcare facilities with the
ability to identify trends in drug utilization and diversion, improve regulatory
compliance and reduce costs by monitoring usage patterns and optimizing product
management.
 
Our goal is to become the leading provider of clinical infrastructure and
workflow automation solutions for the healthcare industry. We will continue to
be innovative in the expansion and enhancement of our product offerings. We also
intend to expand the adoption of our automation solutions by continuing to
collaborate with leading healthcare organizations. Furthermore, we believe our
sizable installed customer base provides us with a significant opportunity to
grow our business through increased sales to our existing customers.
 
INDUSTRY BACKGROUND
 
The healthcare delivery system in the United States is highly fragmented,
complex and inefficient. Despite significant advances in science and medical
technology, the clinical and management processes employed in healthcare
facilities have made little progress in the past 20 years. Presently, many major
clinical workflow processes at healthcare facilities are still predominantly
manual and paper-based, which reflect healthcare facilities' relatively limited
investment in information technology. Gartner, Inc., an independent market
research organization, estimates that for 2001 the healthcare industry will
invest only 1.6% of its revenue in information technology compared to 13.2% and
5.6% for the communications industry and retail industry, respectively.
 
Existing healthcare information systems are also limited in their ability to
support the modernization of healthcare delivery processes or to address
evolving patient safety initiatives, requirements of managed care and new
healthcare regulations. Today, most healthcare facilities' information systems
are oriented toward financial functions such as patient billing. These systems
generally do not provide current, real-time information that healthcare
providers need to make clinical and managerial decisions. Furthermore,
individual departments within the same healthcare facility or network frequently
purchase separate systems customized to their specific requirements, forcing the
healthcare facility to maintain disparate information systems that do not
operate or interface well with one another.
 
                                       32

NEED FOR CLINICAL INFRASTRUCTURE SYSTEMS
 
In November 1999, the Institute of Medicine issued a report based on the results
of over 30 independent studies appearing in medical peer review journals over a
12-year period. The report indicated that medical errors are among the top ten
causes of death in the United States, accounting for more deaths than motor
vehicle accidents, breast cancer or AIDS. The report also indicated that in 1993
over 7,000 deaths resulted from medication errors. The following findings were
noted in the report:
 
    - A 1995 study of 4,031 adult admissions to 11 medical and surgical units at
      two hospitals estimated that an average of 1,900 adverse drug events occur
      per hospital per year, with 28% judged to be preventable.
 
    - The same 1995 study found that approximately three out of every four
      medication errors were caused by one of seven types of systems failures,
      including drug knowledge dissemination, dose and identity checking, order
      transcription and medication order tracking.
 
    - A 1997 study of two hospitals over a six-month period estimated that
      approximately 2% of admissions experienced a preventable adverse drug
      event, resulting in average increased hospital costs of $4,700 per adverse
      drug event admission or approximately $2.8 million annually for a 700-bed
      hospital.
 
In March 2001, the Institute of Medicine issued a follow-up report that
recommended increased investment in information technology as a means of
reducing medical errors and improving the overall quality of patient care.
 
Since the 1999 Institute of Medicine report was released, California has passed
legislation requiring the eventual adoption of technologies aimed at reducing
avoidable medication errors. Other states are considering similar legislation.
Additionally, a consortium of large employers known as the Leapfrog Group was
recently formed with the express purpose of pressuring healthcare facilities to
provide safer care for employees of Leapfrog member companies. The Leapfrog
Group's members, which include companies such as AT&T, Ford Motor Company,
General Electric, IBM and 3M, employ approximately 26 million people and spend
an estimated $45 billion annually on healthcare. One of the initiatives of the
Leapfrog Group is to encourage employees to use healthcare facilities that
invest in computerized systems designed to prevent avoidable medical errors.
 
In January 2001, the JCAHO, an independent, not-for-profit organization that
evaluates and accredits approximately 19,000 healthcare facilities in the United
States, approved standards directly focused on patient safety and medical error
reduction in healthcare facilities. Healthcare facilities seeking accreditation
from the JCAHO are required to establish ongoing patient safety programs,
including the application of knowledge-based information to reduce risks to
patients and the creation of an environment that encourages identification of
errors, establishment of remedial steps to reduce the likelihood of recurring
errors and identification of risks to patients.
 
ECONOMIC PRESSURES ON HEALTHCARE FACILITIES
 
Throughout the 1990s, the increasing cost of providing healthcare led to the
rise of managed care. Healthcare providers aligned into networks and health
plans established guidelines for reimbursement for healthcare delivery, reducing
overall reimbursement rates. Federal policy in the United States also influenced
the economic climate of the healthcare industry. Passage of the Balanced Budget
Act of 1997 proposed a reduction of payments to healthcare providers of more
than $250 billion over a five-year period. This significantly reduced the
operating margins of healthcare facilities and limited their access to capital.
Although these pressures resulted in lower total spending on healthcare, many of
the larger systemic issues in the industry have not been adequately addressed,
including improving patient care and upgrading outdated information systems.
 
                                       33
<Page>
Economic pressures and the need to negotiate more effectively with managed care
organizations have also induced a wave of consolidation, both vertically and
horizontally, among healthcare providers to form newly defined delivery
organizations. Many of these newly created organizations expected to realize
significant economies of scale as a result of consolidation. These economies of
scale have not fully materialized, however, and new problems have emerged from
consolidation, including inefficiencies associated with managing disconnected
and disparate information systems. Integrated delivery networks are only now
beginning to address these issues.
 
Labor shortages in the U.S. healthcare market also have adversely impacted
patient care and accentuated the need for investment in information technology
to improve labor productivity. A December 2000 report from the U.S. Department
of Health and Human Services indicated that the United States is experiencing a
growing shortage of licensed pharmacists, a trend that it expects to continue.
According to the report, the shortage has resulted in less time for pharmacists
to counsel patients, longer working hours and a greater potential for
fatigue-related errors. Similarly, according to the American Organization of
Nurse Executives, most regions in the United States are also experiencing a
major nursing shortage. In February 2001, a survey by the American Nursing
Association revealed that 75% of nurses feel the quality of patient care has
declined over the past two years, and a majority of nurses cited inadequate
staffing as the primary cause of this decline.
 
THE OMNICELL SOLUTION
 
We provide an integrated suite of clinical infrastructure and workflow
automation solutions capable of enterprise-wide implementation by healthcare
providers. These solutions include pharmacy and supply systems, clinical
reference tools, an integrated Internet-based procurement application and
decision support capabilities. Our solutions enable healthcare providers to:
 
    - REDUCE MEDICATION ERRORS.  Our pharmacy systems (i) track clinician,
      patient and drug data, (ii) display a patient's full drug profile,
      (iii) alert clinicians to allergies and drug interactions and (iv) track
      late or missed doses. Our systems interface directly with a healthcare
      facility's clinical pharmacy system, facilitating the dissemination of
      clinical pharmacy data and effectively extending the pharmacist's control
      of dispensed pharmaceuticals to the point of care. Our pharmacy systems
      are typically equipped with a touch screen Web browser that provides
      direct access to a third-party drug information database. This
      functionality allows clinicians to review information on dosage,
      administration, contra-indications and drug interactions at the point of
      care. Our pharmacy systems also support drug error detection by providing
      direct access, via the Internet, to medication error reporting and
      analysis software.
 
    - REDUCE COSTS.  Our pharmacy and supply systems store pharmaceuticals and
      medical supplies in a closed, controlled environment. By requiring a
      caregiver to enter their identification code and select a patient's name
      before removing a pharmaceutical or supply, only the items needed for each
      particular patient procedure are removed. This ensures that items are
      allocated properly and charged to the appropriate patient. Our automation
      systems also capture data on product utilization and inventory levels in
      real-time, allowing pharmacy and materials management departments to avoid
      shortages in care areas, improving patient care. Furthermore, by comparing
      actual utilization rates with standing inventory levels, business managers
      can optimize inventory levels across the entire enterprise. By controlling
      and monitoring access to pharmaceuticals and supplies, our systems also
      discourage stockpiling or theft. We estimate that our supply systems can
      reduce our customers' annual supply consumption costs by approximately 15%
      to 20% and reduce their required inventory levels by approximately 25% to
      30%.
 
    - IMPROVE OPERATING EFFICIENCY.  Our pharmacy and supply systems accurately
      capture data by patient, physician, location and billing code. These
      systems interface with our customers' existing clinical pharmacy,
      financial and materials management systems to automate such processes as
      medication reporting, patient billing and inventory replenishment. This
      eliminates manual
 
                                       34
<Page>
      processes and provides our customers with immediate access to data
      gathered by our systems to facilitate real-time operations management. Use
      of our pharmacy and supply systems also reduces process costs and
      increases labor productivity, enabling caregivers to devote more time to
      delivering patient care and allowing support personnel to provide
      additional services with fewer people. We estimate that our supply systems
      can reduce our customers' personnel needs by 1.5 full-time equivalent
      employees for every 100 occupied hospital beds.
 
    - LEVERAGE INVESTMENTS IN EXISTING INFORMATION SYSTEMS.  Because our
      automation solutions are designed to integrate with healthcare facilities'
      existing clinical pharmacy, financial and materials management systems, we
      can preserve their existing investments in these systems and enhance those
      systems' functionality. We have developed over 1,500 live, proprietary
      software interfaces that integrate our automation solutions with
      healthcare facilities' existing information systems. We believe our
      interface capabilities make our solutions particularly useful to large
      enterprises, such as integrated delivery networks, that often use
      multiple, disparate information systems among their facilities.
 
    - SIMPLIFY ORDERING PROCESSES.  Our Internet-based procurement application,
      OmniBuyer, simplifies the predominantly manual, paper-based procurement
      processes that currently exist in most healthcare facilities. By
      automating the purchasing process, OmniBuyer reduces administrative work
      and processing costs, increases contract compliance and improves order
      accuracy and information management. Used in conjunction with our pharmacy
      and supply systems, our customers are able to benefit from a fully
      electronic supply chain, from selected suppliers to the point of use. We
      estimate that OmniBuyer reduces the cost of issuing a purchase order from
      an average of $75 to $125 per purchase order to $15 to $30.
 
    - MONITOR UTILIZATION TRENDS.  Our Internet-enabled decision support tool,
      DecisionCenter, tracks pharmaceutical and supply utilization by physician,
      patient, procedure, item and diagnosis code. DecisionCenter provides
      healthcare facilities with the ability to identify trends in drug
      utilization and diversion, improve regulatory compliance and reduce costs
      by monitoring usage patterns and optimizing product management.
      DecisionCenter also provides secured trend analysis, decision support and
      regulatory compliance reports based on data gathered from our pharmacy and
      supply systems and other information systems within the healthcare
      facility.
 
STRATEGY
 
Our goal is to become the leading provider of clinical infrastructure and
workflow automation solutions for the healthcare industry. We intend to achieve
this goal through the following strategies:
 
    - CONTINUE TO LEVERAGE AND EXTEND OUR SOLUTIONS.  We intend to continue to
      develop features and functionality for our automation solutions that
      address the patient safety and cost-containment pressures confronting
      healthcare facilities. In addition, we intend to continue to add software,
      hardware and Internet-based solutions that complement and extend our
      automation solutions. For example, in 1999, we introduced OmniBuyer, which
      automates healthcare facilities' purchasing processes, to provide a
      complementary service to our pharmacy and supply systems.
 
    - COLLABORATE WITH LEADING HEALTHCARE PROVIDERS.  We work closely with
      leading healthcare institutions, such as the Cleveland Clinic,
      Massachusetts General Hospital and New York University Hospitals Center,
      in the definition, development and deployment of our products and
      services. These institutions demand innovative and cost-effective products
      and services that address their clinical infrastructure and workflow
      automation needs. They also require that our products and services be
      comprehensive in scope and capable of supporting the operations of an
      entire healthcare enterprise. Through our collaborations with leading
      healthcare institutions, we seek to establish our automation solutions as
      industry standards for clinical infrastructure and workflow automation.
 
                                       35
<Page>
    - FURTHER PENETRATE OUR INSTALLED CUSTOMER BASE.  We have a sizable
      installed base of over 18,600 pharmacy and supply systems in over
      1,100 healthcare facilities. Most of our customers have purchased only a
      subset of our products and services, or have not yet implemented our
      products and services throughout their facilities. As a result, we believe
      a significant opportunity exists to expand sales to our existing
      customers. We intend to leverage our close customer relationships and the
      measurable benefits of our products and services to capitalize on this
      opportunity.
 
    - DEVELOP SOLUTIONS THAT ENHANCE OUR CUSTOMERS' EXISTING SYSTEMS.  We expect
      healthcare facilities to continue to demand our clinical infrastructure
      and workflow automation solutions as a means to preserve, leverage and
      upgrade their existing information systems. We will continue to deliver
      Internet-based and fully integrated automation solutions that are
      cost-effective and enhance our customers' existing information systems. We
      will also continue to utilize our dedicated interface team, proprietary
      hardware and software interface technologies and over 1,500 live
      interfaces to fully integrate our automation solutions with our customers'
      existing information systems.
 
    - DEVELOP STRATEGIC RELATIONSHIPS.  We expect to continue to enter into
      strategic relationships that enhance our product offerings, broaden our
      automation solutions and increase our sales opportunities. We expect these
      relationships to increase the clinical efficacy of our automation
      solutions and open new markets for them. We currently have a relationship
      with Gold Standard Multimedia whose Clinical Pharmacology database
      connects to our pharmacy systems through the Internet, providing important
      drug allergy and drug interaction information to clinicians as they remove
      medications from our pharmacy systems. We also have a strategic
      relationship with Becton, Dickinson and Company that allows us to
      co-market their bedside Rx System for prevention of medication errors to
      our installed customer base. The Becton Dickinson system is intended to be
      fully integrated with our pharmacy systems to promote maximum safety in
      the delivery of medications to the patient while automating and enhancing
      workflow.
 
OMNICELL PRODUCTS AND SERVICES
 
Our automation solutions include pharmacy and supply systems, an Internet-based
procurement application and decision support capabilities. Our pharmacy and
supply systems consist of modular, secured and computerized cabinets and related
software technology that manage and dispense pharmaceuticals and medical
supplies. OmniBuyer automates the healthcare facility's requisition process, and
DecisionCenter provides trend analysis and decision support based on data
gathered by our pharmacy and supply systems. In pricing our products and
services, we take into account our costs of production, customer feedback and
our competitors' prices. In general, the minimum initial price for one of our
pharmacy and supply systems is approximately $20,000. However, most of our
customers purchase multiple systems, totaling $300,000 to $400,000. A number of
our customers have purchased and installed over $1 million of our pharmacy and
supply systems.
 
PHARMACY SYSTEMS
 
We offer two lines of pharmacy systems, Omnicell and Sure-Med. Our Omnicell
pharmacy systems are highly configurable and are typically installed with
high-resolution color touch screens. Our color touch screens provide users with
a Windows-based graphical interface that is suited for displaying a patient's
medical profile and Internet-based clinical information. In addition, our
Omnicell pharmacy systems have dispensing drawers that support multiple levels
of security by utilizing single-dose lids, locking lids, sensing lids and
patented guiding lights. The systems are configured to support clinical workflow
in all areas of the hospital including the operating rooms, emergency rooms,
intensive care units and medical/ surgical floors.
 
We acquired the Sure-Med pharmacy system from Baxter Healthcare in 1999. Our
Sure-Med systems incorporate a variety of storage compartments and software that
is compatible with all of our
 
                                       36
<Page>
automation solutions. Our Sure-Med systems offer a wide range of configuration
and dispensing technologies, including unit-dose dispensers and multiple drawer
sizes. The unit-dose module dispenses only the requested medication doses and is
best suited for medications where regulatory guidelines mandate a highly
controlled environment. Clinicians prefer this technology in high-security
situations because it automates much of the logistical and documentation burden
and responsibility associated with dispensing controlled medications. In late
2000, we extended our color touch screens and associated software available on
our Omnicell pharmacy system to the Sure-Med pharmacy system. This will enable
both systems to function on a common platform, allowing customers to add our
other products to their Sure-Med pharmacy systems. We expect broad adoption of
this new technology across our Sure-Med installed base.
 
SUPPLY SYSTEMS
 
Our primary supply systems are comprised of one, two or three cabinets. Each
cabinet is approximately two feet wide, six feet high and two feet deep with
capacity for up to 120 stock keeping units. Auxiliary cabinets can be added to
the system to provide additional storage capacity. Various shelf, drawer and
rack modules facilitate a wide array of storage configurations.
 
Our supply systems incorporate locked transparent doors that restrict access to
the supplies contained in our systems. Users enter their identification number
on a console and select the appropriate patient name. Specific doors then open
based on the security level of the user. Using our patented "See & Touch"
technology, the user is able to record supply utilization by pushing a dedicated
reorder button on the shelf in front of the selected item.
 
COMBINATION SYSTEMS
 
Our combination systems allow healthcare organizations to store pharmaceuticals
and medical supplies in a single system. The architecture of our combination
system enables each operating department to manage its products independently of
other operating departments, restricting clinician and technician access to only
appropriate pharmaceuticals and medical supplies and allowing the tracking of
transaction data, inventory levels, expenses and patient treatment costs through
a single database. By utilizing our combination systems, healthcare facilities
are able to handle pharmaceuticals and medical supplies with greater flexibility
and efficiency.
 
OMNICENTER
 
OmniCenter is a computerized central server that processes transaction data to
and from our pharmacy and supply systems, recording each transaction by user,
patient, item quantity, cost, date and time. OmniCenter enables the pharmacy and
materials management departments to run reports automatically or on demand,
indicating when to restock the systems and when to reorder pharmaceuticals and
supplies. OmniCenter also permits the user to generate a wide range of standard
and customized reports. As a diagnostic service, we are able to remotely access
an installed OmniCenter from our technical support center to monitor the status
of the server and all installed pharmacy and supply systems.
 
OMNIBUYER
 
OmniBuyer is a secure Internet-based procurement application that automates and
integrates a healthcare facility's requisition and approval processes. The
application incorporates buyer-specific business rules, such as spending limits,
negotiated pricing, approval routing and customized access profiles. In
addition, OmniBuyer is integrated with the healthcare facility's existing
information systems, further streamlining the purchasing process. OmniBuyer is
based on Commerce One's BuySite technology that we have customized to meet the
complex needs of the healthcare industry.
 
                                       37
<Page>
OmniBuyer provides a single online point of entry to meet the procurement needs
of buyers at healthcare facilities. We typically sell OmniBuyer on an
application service provider basis. Using OmniBuyer, our customers determine the
specific suppliers, including manufacturers, distributors, marketplaces and
exchanges, to which their buyers will have access.
 
DECISIONCENTER
 
DecisionCenter is an Internet-enabled decision support product that provides
secure trend analysis, decision support and regulatory compliance reports based
on data from our pharmacy and supply systems. It consolidates information from
one or more OmniCenters into one database. The data are stored in a raw format
as well as aggregated for rapid response to queries. We have developed the
"My-Omni" Web page that allows users to configure frequently requested
information from a short menu. In addition, we offer sophisticated graphical
tools that allow users to make detailed queries across all data fields. These
systems are typically interfaced with the healthcare facility's medical records
system in order to augment the database with correctly associated diagnosis
codes. Data can be viewed by authorized users and personnel at any time,
allowing for easy and comprehensive analysis to improve decision making.
 
SERVICES
 
We provide three types of services in support of our automation solutions:
(i) post-sales installation services at customer facilities, provided by our
field service organization; (ii) integration services in which our interface
development team interfaces our solutions with our customers' existing clinical
pharmacy, financial, and materials management systems; and
(iii) post-installation technical support. We generate revenue from service
contracts for post-installation technical support, which provides our customers
with phone support, on-site service, parts, and access to software upgrades.
On-site service is provided by a combination of our field service operations
team, technical support group and 150 field service representatives from Dade
Behring Inc., a third-party service company.
 
MEDCENTERCITY
 
We own and operate MedCenterCity, a Web site for healthcare professionals, as a
service to the healthcare community. The site includes articles on relevant
issues, including the cost of healthcare, reducing medical errors and the
Healthcare Information Portability and Accountability Act of 1996.
 
CUSTOMERS
 

Our target customers for our automation solutions are healthcare facilities,
including hospitals and alternate care facilities. As of March 31, 2001, over
1,100 hospitals and specialty care facilities had purchased or leased our
pharmacy and supply systems. The following entities are our 15 largest hospital
customers which have first purchased or leased pharmacy and supply systems since
1997:

ASCENSION HEALTH
 

Ascension Health, headquartered in St. Louis, Missouri, is the largest
non-profit healthcare system in the United States, with a network of more than
75 hospital, specialty care and other healthcare facilities in 15 states and the
District of Columbia. In July 2001, we entered into a five-year technology
sharing and license agreement with Ascension, with the option to renew for an
additional five-year term. Under the terms of the agreement, we agreed to
provide OmniBuyer to the entire Ascension system.

 
RUSH-PRESBYTERIAN CASE STUDY
 
Rush-Presbyterian-St. Luke's Medical Center in Chicago, Illinois is an example
of a healthcare facility progressively adopting our automation solutions to
derive benefits across the enterprise. In December 1993, Rush-Presbyterian
installed our supply systems in an area of its facility called the Atrium. A
two-year retrospective study was performed by Rush-Presbyterian and us to assess
the long-term impact of our supply systems on Rush-Presbyterian's inventory
management processes. The study found that total supply consumption in the
Atrium for the first year, 1994, declined by almost $150,000 or 20.3% versus the
baseline year. In 1995, total supply consumption in the Atrium dropped an
additional $30,000 below the already reduced first-year level, to 24.3% below
the baseline year. Rush-Presbyterian has expanded its use of our supply systems
to other areas of the facility, including the Cardiovascular Catheterization
Unit (CVCU).
 
In November 1999, Rush-Presbyterian implemented OmniBuyer in the CVCU. In the
CVCU, Rush-Presbyterian has automated the procurement process from the point of
use to the supplier. The automation process begins when an item such as a
catheter is removed from one of our supply systems. The user then pushes a
dedicated reorder button for each item removed. The usage data generated by
these transactions are consolidated by our OmniCenter, which interfaces with
OmniBuyer. When a reorder point is reached, the manager of the CVCU receives an
automatic e-mail message, notifying him to log on to OmniBuyer, where he views a
requisition detailing the products to be reordered. The manager is then able to
edit and approve the requisition. Once approved, OmniBuyer transmits the
requisition to the supplier, accessing current pricing information from the
supplier and sends the order to the Rush-Presbyterian enterprise resource
planning system in order to generate an accurate purchase order. After the
requisition has been received and processed by the supplier, an e-mail message
is sent back to the requisitioner to verify that the order has been received and
processed. The e-mail message identifies backorder status, which is helpful if a
different supplier needs to be contacted to obtain a required product. The
e-mail message also identifies discrepancies in supplier pricing by comparing
automatically purchased goods to contract prices. This feature has already saved
Rush-Presbyterian thousands of dollars in inadvertent supplier overcharges.
 
STRATEGIC RELATIONSHIPS
 
We establish and maintain relationships with companies whose products, services,
technologies and/or market presence enhance our ability to deliver value to our
customers and who open up additional sales opportunities for our automation
solutions. With the exception of Bergen Brunswig and our August 1999 agreement
Commerce One, we believe that alternative arrangements could be secured in the
event of termination of agreements with the companies listed below. Among the
most significant relationships are the following:
 
BERGEN BRUNSWIG CORPORATION
 
Bergen Brunswig Corporation is a leading supplier of pharmaceuticals and
specialty healthcare products as well as information management solutions and
consulting services. In July 2001, we entered into a strategic partnership with
Bergen Brunswig whereby both parties agreed to collaborate in certain sales
situations and to respond jointly, where appropriate, to customer requests for
proposals. We have
 
                                       39

further agreed to collaborate to integrate our pharmacy systems and OmniBuyer
with Bergen Brunswig's distribution services and software platform, InterLinx,
to enable our joint customers to automate the workflow associated with procuring
and distributing pharmaceuticals from Bergen Brunswig. The agreement has an
initial term of five years, with an option to renew thereafter. In connection
with the agreement, we have requested that the underwriter reserve for sale, at
the initial public offering price, up to $5 million of our common stock in the
offering for Bergen Brunswig. In the event Bergen Brunswig purchases reserved
shares in the offering or otherwise makes a private investment in Omnicell of at
least $3 million by December 31, 2001, we will become obligated to pay a
commission to Bergen Brunswig on future sales of our products attributable to
the collaboration with Bergen Brunswig.
 
In March 2001, Bergen Brunswig entered into a merger agreement with AmeriSource
Health Corporation to create a new company called AmeriSource-Bergen
Corporation. The merger is still pending approval from each of the company's
shareholders and the Federal Trade Commission. We do not anticipate that our
relationship with Bergen Brunswig would be affected by the completion of this
transaction.
 
BECTON, DICKINSON AND COMPANY
 
Becton Dickinson is a manufacturer of medical supplies, devices and diagnostic
systems, including the BD Rx System. The BD Rx System allows nurses to perform a
final, bedside safety check by positively identifying the correct patient,
medication, dosage, time and method of delivery before administering the
medication. The system utilizes a sophisticated hand-held computing platform and
bar code scanner that a nurse can transport from patient to patient. In June
2000, we agreed to co-market the BD Rx System to our installed base of pharmacy
system customers.
 
GOLD STANDARD MULTIMEDIA (CLINICAL PHARMACOLOGY)
 
Gold Standard Multimedia is a provider of multimedia programs for the healthcare
market. Gold Standard Multimedia's drug information application, Clinical
Pharmacology, was named eHealthcareWorld's 1999 Gold Award winner for best
online publication for professionals. We have an agreement with Gold Standard
Multimedia to make the Clinical Pharmacology database available to our customers
through the Web browser loaded onto all of our color touch screens. Access to
the database is integrated with our pharmacy systems so that when a nurse
removes a drug for a patient, commands are processed through the browser that
make clinical information about that drug available to the nurse on our color
touch screen. The nurse can view allergy and drug interaction information,
locate specific details and view an image of the drug. We believe that access to
these types of information from our pharmacy systems can prevent medication
errors. Clinical Pharmacology also provides drug information that nurses can
print for patients prior to discharge to reinforce patient education.
 
U.S. PHARMACOPEIA
 
U.S. Pharmacopeia is a non-profit organization that establishes standards to
ensure the quality of medicines. We have a co-marketing agreement with
U.S. Pharmacopeia that makes their MedMARx medication error reporting and
analysis software available on our pharmacy systems. The MedMARx software
provides a standardized framework for medication error reporting. From our color
touch screen, clinicians can record medication errors, run standard and
customized reports and view the results in chart and graph form. These reports
help clinicians follow trends and pinpoint problem areas. U.S. Pharmacopeia also
maintains a national medication errors database that allows healthcare
facilities to anonymously compare themselves to similar institutions.

ROSEBUD SOLUTIONS
 
Rosebud Solutions provides software solutions that automate the process of
tracking and managing equipment within healthcare facilities. Rosebud Solutions'
Medical Equipment Management Systems (MEMS) solution helps healthcare facilities
improve asset utilization, reduce cost, simplify processes and improve patient
care through better medical equipment management. In particular, MEMS helps
reduce the incidence of hospital-associated infections by tracking incidents of
patient-to-patient equipment transfer and giving healthcare facility personnel a
tool for preventing such transfers. In February 2001, Omnicell entered into an
exclusive reseller agreement with Rosebud Solutions to sell its MEMS program and
other products to our customers.
 
INNOVATIVE PRODUCT ACHIEVEMENTS, INC. (SCRUBAVAIL)
 
Innovative Product Achievements, Inc. is an inventory management systems company
focused on the development of innovative solutions for the management of
materials in healthcare facilities. We co-market Innovative Product
Achievements' ScrubAvail system as an extended offering to our supply systems.
ScrubAvail is an advanced inventory control system for surgical scrub suits. The
ScrubAvail system is typically installed in the operating room, labor and
delivery, emergency room and other high surgical scrub use areas. In the United
States, over 4,000,000 scrub suits are dispensed annually through ScrubAvail
systems.
 
COMMERCE ONE, INC.
 

Commerce One, Inc. is a provider of e-commerce solutions that dynamically link
buying and supplying organizations to form real-time trading communities. In
August 1999, we entered into an agreement with Commerce One and paid a license
fee pursuant to which we received a license to Commerce One's Hosted BuySite
software for use in developing our OmniBuyer application. The agreement also
provides for program management services and ongoing maintenance and support of
the software for additional fees. The agreement continues perpetually unless
otherwise terminated by either party pursuant to the termination provisions of
the agreement. In June 2001, we entered into another agreement with Commerce One
to allow us to co-sell the licensed version of Commerce One's BuySite software.
In addition, our strategic relationship with Commerce One allows for
co-marketing and co-development efforts and enables us to utilize their
e-commerce technology platform and access their Global Trading Web. In March
2000, Commerce One made an equity investment in our company.

 
RESEARCH AND DEVELOPMENT
 
We commit significant resources to developing new products and technologies that
bring value to our customers. We believe that our research and development focus
and quality team are key competitive advantages in the industry. As of June 30,
2001, we have 63 employees in research and development, approximately 17% of our
entire workforce. Research and development expenses were $6.0 million,
$8.7 million and $11.3 million in the years ended December 31, 1998, 1999 and
2000, respectively, representing 12.4%, 15.8% and 16.7% of total revenues in
those years.
 
Our architecture and sophisticated product development process allow for rapid
development and testing times. The software architecture for our pharmacy and
supply systems is based on database products and development tools centered
around the Microsoft Windows NT platform and the Microsoft Internet Information
Server. This software is installed at the customer site. We develop application
software that is generally applicable to all customers, while retaining broad
customization functionality. We maintain a single release applicable to both our
pharmacy and supply systems, with each new release containing more configurable
options as new features are added, while retaining previous functionality for
backward compatibility. Interfacing with our customer's existing information
systems is done according to the Health Level Seven (HL7) standards or, for
non-compliant systems, is done utilizing our custom interface software.
Interface software is kept separate from the main software
 
                                       41
<Page>
release. Communication between the OmniCenter server and the pharmacy and supply
systems and interface software is accomplished through an application
programming interface. Each new release of server software maintains backward
compatibility with this application programming interface, so that previous
versions of interfaces and pharmacy and supply systems continue to operate when
the OmniCenter server software is upgraded. Our products currently do not
require approvals beyond standard Underwriters Laboratories or Canadian Safety
Association equivalent certification.
 
A vital part of our automation solutions business and among our core
competencies is a dedicated hardware group. While software occupies the majority
of our development resources, the knowledge and expertise of our hardware group
is one of the significant barriers to entry for potential competitors. Since our
pharmacy and supply systems handle physical product, a considerable amount of
skill is required in designing mechanisms that will automatically dispense a
variety of sizes of pharmaceuticals and medical supplies. Our mechanical and
electronic designers use automated design tools to allow full three-dimensional
simulation down to individual piece part drawings. In many cases our design
documentation is transmitted to suppliers electronically.
 
For our OmniBuyer application, our strategic relationship with Commerce One
allows us to incorporate and extend Commerce One's technology platforms,
applications, source code and documentation into healthcare. Their tools allow
us to modify their BuySite software to produce our branded OmniBuyer
application, minimizing the effort to port specific software changes to the
latest Commerce One release.
 
TECHNOLOGY
 
Much of our architecture is based on industry standards such as programming
languages like C++, Visual Basic and Java, standard HL7 healthcare interfaces,
the Microsoft Windows NT operating systems, Intel microprocessors and standard
IEEE 802.11b wireless protocols. Our product development teams employ
object-oriented analysis and design principles to guide the development of an
object-oriented system of software code. Our methodology allows us to utilize
the capabilities of object-oriented programming languages like C++ and Java to
build reusable components and designs. This methodology also helps reduce the
risks inherent in developing complex systems and helps us design our solutions
to meet the needs of our customers.
 
Scalability is a key benefit of our product offering and an area of continuous
focus in our research and development activities. Our pharmacy and supply
systems deploy current industry standard Microsoft Windows NT 4.0 Server
operating software and Pentium-class Intel microprocessors. The OmniCenter
server is designed to support our systems, fully deployed, at the largest
healthcare facility.
 
Historically, we have typically offered a major upgrade to our application
software approximately once a year. Our most recent automation software release
was Omnicell 6000, which became commercially available in February 2001.
Upgrades are included as part of our standard service contract, and the majority
of our customers have a service contract. In some cases, due to requirements of
the underlying operating systems, our customers may need to upgrade older
OmniCenter PC platforms (not the embedded PCs in the systems). In these cases,
our customers are charged a single price for a new PC and on-site installation
of the upgrade and database transfer.
 
Our service contracts include the license to use the software and receive
upgrades. In some cases, certain new features in an upgrade may be chargeable
items. If the customer declines to purchase the chargeable upgrades, then the
upgrade is performed without enabling those chargeable features. In the majority
of cases, upgrades to software functionality may also lead to the purchase of
additional Omnicell proprietary hardware. New releases of OmniBuyer occur
approximately every three months. With each new release, every existing
OmniBuyer customer is upgraded, as part of the ASP hosting fee.
 
Current server hardware is available with single or dual processor platforms
with, or without, redundant arrays of independent disks and power supplies,
depending on the size of the application. In addition to
 
                                       42
<Page>
developing new application features, our software development group makes
continuous improvements to our proprietary applications and communications
software to optimize the speed and performance of our systems. We maintain a
separate software quality assurance department that provides testing of new
features and regression testing of the existing features before we release
software for test sites. At the successful completion of the testing period, the
software is released for general availability.
 
In the Internet-based procurement area, Commerce One's solution utilizes XML
software technology platform servers to generate and securely transmit XML
documents over the Internet. Commerce One has also created a common business
library designed to enable a common language-based framework for uniting
disparate business document types. While we believe that XML software technology
is emerging as an industry standard for business-to-business electronic
commerce, we have also developed translation technology that converts XML
documents into other document formats. This translation technology allows us to
deliver purchase orders to suppliers in a wide variety of document formats,
including electronic data interchange, Open Buying on the Internet, ASCII flat
file, e-mail, Microsoft Excel and facsimile.
 
Our Internet-based products use 128-bit encryption, HTTPS-SSL and
password-protected user access. Our servers are located behind corporate
firewalls and access is multiple password-protected. We recognize our
obligations to safeguard patient information and other customers' proprietary or
confidential information to which we may have access through the use of our
automation systems and OmniBuyer. We have implemented a Privacy and Use of
Information Policy and strictly adhere to established privacy principles, use of
customer information guidelines and federal and state statutes and regulations
regarding privacy and confidentiality, including those measures and practices
required under the Health Insurance Portability and Accountability Act of 1996.
 
SALES, MARKETING AND CUSTOMER SUPPORT
 
We market and sell our products and services to a variety of healthcare
organizations, including hospitals and alternate care facilities, targeting
hospitals with over 100 beds and alternate care organizations with multiple
facilities. In the United States and Canada, we have a direct sales force
organized into six regions. We sell through distributors in Europe, the Middle
East, Asia and Australia. Each of the members of our direct sales force sells
our pharmacy and supply systems, OmniBuyer and DecisionCenter. Our sales
representatives have, on average, over eight years of sales experience in the
healthcare industry. A regional vice president coordinates both the sales and
field service operations activities in each region.
 
Our marketing group is responsible for product marketing, marketing
communications, Web site development, public relations, sales support and
training. It generates leads through a variety of means, including advertising,
direct marketing and participation in trade shows and conferences covering such
areas as pharmacy, nursing, anesthesiology, operating room management, hospital
administration, materials management, electronic commerce and supply chain
management.
 
The sales cycle for our automation systems is long and can take in excess of
12 months. This is due in part to the cost of our systems and the number of
people within a healthcare facility involved in the purchasing decision. To
initiate the selling process, the sales representative generally targets the
director of pharmacy, the director of materials management and/or other decision
makers and is responsible for educating each group within the healthcare
facility about the benefits of automation. To assist hospitals in the
acquisition of our systems, we offer multi-year, non-cancelable leases that
reduce up-front acquisition costs. Typically, we sell our customers' lease
agreements to a third-party leasing company. We have contracts with several
group purchasing organizations (GPOs) that enable us to sell our automation
systems to GPO-member healthcare facilities without going through a lengthy
request for proposal and bidding process. These GPO contracts are typically for
multiple years with options to renew or extend for up to two years but can be
terminated by either party at any time. Our current
 
                                       43
<Page>
GPO contracts include Premier, Inc., Novation, LLC, Consorta Catholic Resources
Partners, Tenet Healthcare Corporation and the Department of Veterans Affairs.
 
Our field service operations representatives support our sales force by
providing operational and clinical expertise prior to the close of a sale and
installing our automation systems post-sale. This group assists the customer
with the technical implementation of our automation systems, including
configuring our systems to address the specific needs of each individual
customer. After the systems are installed, on-site support is provided by a
combination of our field service operations team, technical support group and a
third-party service company.
 
We offer technical support through our technical support center in Waukegan,
Illinois. The support center is staffed 24 hours a day, 365 days a year. We use
the Siebel Systems software package, an industry standard for call centers, to
field calls from customers. We have found that two-thirds of all service issues
can be addressed either over the phone or by our support center personnel
utilizing their on-hand remote diagnostics tools. In addition, we utilize remote
dial-in software that monitors customer conditions on a daily basis.
 
We leverage our sales and field service organizations, along with our technical
support center, to sell, implement and support OmniBuyer. In addition, we have
added specialists who work solely with healthcare facilities to implement
OmniBuyer. The implementation process is done in phases. We work with each
healthcare facility to determine its purchasing and approval flows. We also
interface OmniBuyer to all relevant information systems, assist with
connectivity to suppliers, marketplaces and exchanges and provide training on
the application.
 
MANUFACTURING OF PHARMACY AND SUPPLY SYSTEMS
 
Our pharmacy and supply systems manufacturing strategy is to produce custom
configured systems with rapid turnaround in a high-quality and cost-effective
manner. We currently conduct our manufacturing operation in a 23,000 square foot
facility in Palo Alto, California operating on one shift. We operate on a
continuous flow, just-in-time basis to perform final assembly, configuration and
system testing of all products. Our customer service personnel work closely with
the end user to determine specific customer requirements for each installation.
The detailed customer requirements are transmitted electronically to our
manufacturing facility where they are used to custom configure each unit. Our
operating software is installed as a part of the assembly process. Once
assembled, every unit undergoes mechanical and systems testing prior to
shipping.
 
Our production activities consist primarily of final assembly of mechanical
components and electronic sub-systems outsourced to key suppliers. While many
components of our systems are standardized and available from multiple sources,
certain components or subsystems are fabricated according to our specifications.
We endeavor to obtain multiple sources of supplies for certain components. We
believe we could obtain alternative sources of supplies within two to four
months if our current suppliers were unable to provide us with adequate
quantities of such components.
 
Our products are designed with a high degree of modularity that facilitates
manufacturing, assembly and configuration and enables rapid deployment of new
products and product enhancements. We have automated much of the software
quality assurance process and have streamlined key steps in the mechanical
prototyping process in order to minimize the time from design prototype to
volume production. We work closely with several key fabricators and subassembly
manufacturers on new products and utilize lower-cost manufacturers whenever
possible while maintaining product quality and availability. We are continuously
re-engineering our products to reduce manufacturing costs while improving
product reliability and serviceability.
 
Our quality assurance team inspects and creates an electronic record for every
product before it is shipped using personal digital assistants. This information
is used to monitor workmanship by recording the number of defects per thousand
units. Each manufacturing employee is part of an incentive
 
                                       44
<Page>
program tied to reducing defects per thousand units. Quality issues are gathered
through weekly field updates and direct calls from our sales and customer
support groups. These issues are addressed in weekly reliability meetings, which
bring together our engineering, manufacturing and quality assurance teams.
 
COMPETITION
 
The clinical infrastructure and workflow automation market is intensely
competitive and characterized by evolving technology and industry standards,
frequent new product introductions and dynamic customer requirements. Many
healthcare facilities still use and may continue to use highly manual approaches
that do not utilize automated methods of distribution, inventory tracking or
procurement. As a result, we must continuously educate existing and prospective
customers regarding the advantages of our products.
 
We expect continued and increased competition from current and future
competitors, many of which have greater financial, technical, marketing and
other resources. Our current direct competitors in the pharmacy and supply
systems market include Pyxis Corporation (a division of Cardinal Health) and
Automated Healthcare (a division of McKessonHBOC).
 
We believe that companies in the clinical infrastructure and workflow automation
market compete based on:
 
    - breadth and depth of product offerings;
 
    - ease of use and efficiency;
 
    - ability to incorporate the customer's requisition and approval process;
 
    - ability to integrate their services with the customer's existing systems
      and software;
 
    - quality and reliability of product offerings;
 
    - customer service; and
 
    - price.
 
We believe our products and services compare favorably with those offered by our
competitors, particularly in the areas of flexibility, utilization of advanced
technologies, ease of use and quality of integration with existing systems.
 
GOVERNMENT REGULATION
 
The manufacture and sale of our current products are not regulated by the FDA.
There can be no assurance, however, that these products, or future products, if
any, will not be regulated in the future. A requirement for FDA approval could
harm our business, results of operations and financial condition. The practice
of pharmacy is governed by individual state boards of pharmacy that issue rules
for pharmacy licensure in their respective jurisdictions. State boards of
pharmacy do not license or approve our distribution systems. However, pharmacies
using our equipment are subject to state board approval. Similarly, hospitals
must be accredited by the JCAHO in order to be eligible for Medicaid and
Medicare funds. The JCAHO does not approve or accredit distribution systems.
 
Our online services may be subject to a number of laws and regulations that may
be adopted or interpreted in the United States and abroad with particular
applicability to the Internet. The laws governing Internet transactions remain
largely unsettled, even in areas where there has been some legislative action,
such as the federal Internet Tax Freedom Act. It is possible that U.S. and
foreign governments will enact legislation that may be applicable to us in areas
including content, product distribution, network security, encryption, the use
of measures for data and privacy protection, electronic authentication, access
charges and re-transmission activities. The adoption or modification of laws or
regulations relating to the Internet or its related technologies could have a
material adverse
 
                                       45
<Page>
effect on our OmniBuyer application and also adversely affect our business by
increasing our costs and administrative burdens. It may take years to determine
whether and how existing laws such as those governing intellectual property,
privacy, libel, consumer protection and taxation apply to the Internet. We
believe that our Privacy and Use of Information Policy to be posted on our Web
site addresses the concerns raised by the recent privacy initiative of the
Federal Trade Commission. However, we cannot assure you that this initiative
will not negatively affect our business. Compliance with any newly adopted laws
may prove difficult for us and could harm our business.
 
PROPRIETARY RIGHTS AND LICENSING
 

Our success depends in part upon a combination of copyright and trademark laws,
trade secrets, confidentiality procedures and contractual provisions to protect
our proprietary rights. We pursue patent protection in the United States and
foreign jurisdictions for technology that we believe to be proprietary and that
offers a potential competitive advantage for our products. We currently own
eleven U.S. patents, two of which are co-owned, that will expire between 2010
and 2017. In addition, we currently have one U.S. patent allowed and awaiting
issue and have filed six U.S. patent applications. The issued patents relate to
our "See & Touch" methodology used in our pharmacy and supply systems, the use
of guiding lights in the open matrix pharmacy drawers, the use of locking and
sensing lids with pharmacy drawers and the methods of restocking these drawers.
The above referenced patents also apply to our unit-dose mechanism and methods,
the single-dose dispensing mechanism and the methods for restocking the
single-dose drawers using exchange liners. There are other issued patents and
applications in process in Australia, Japan, Hong Kong, Canada and European
countries related to issued and pending applications in the United States. We
are aware of one third-party patent issued several years ago that may relate to
certain of our products. Although we have received no notice alleging
infringement from this third party to date, there can be no assurance that such
third party will not assert an infringement claim against us in the future.
Other than this patent, we are not aware that any of our products infringes the
proprietary rights of any third parties.

 
All of our operating system software is copyrighted and subject to the
protection of applicable copyright laws. We have also obtained registration of
our Omnicell logo, Omnicell, OmniCenter, OmniSupplier, OmniRx and Sure-Med
trademarks through the United States Patent and Trademark Office. We are in the
process of registering other trademarks, in the United States and
internationally. We seek to protect and enforce our rights in our patents,
copyrights, service marks, trademarks, trade dress and trade secrets through a
combination of laws and contractual restrictions, such as confidentiality and
licensing agreements.
 
FACILITIES
 
We lease approximately 113,000 square feet of office, development and
manufacturing space in Palo Alto, California and Waukegan, Illinois. Our
principal administrative, marketing and research and development facilities are
located in approximately 34,000 square feet of leased office space in Palo Alto,
California under leases expiring in January 2002 and June 2004. Our principal
manufacturing facility is located in approximately 23,000 square feet of leased
space in Palo Alto, California under a lease expiring in June 2003, with an
option to renew for an additional five years. We also maintain an
administrative, marketing, development, technical support and training facility
located in approximately 38,000 square feet of leased office space in Waukegan,
Illinois under a lease expiring in June 2006, with an option to renew for an
additional five years.
 
EMPLOYEES
 
As of June 30, 2001, we had a total of 369 employees, including 63 in research
and development, 68 in sales, 21 in marketing, 129 in customer support, 41 in
administration and 47 in manufacturing. We also employ independent contractors
and temporary personnel to support our development, marketing, customer support,
field service and administration organizations. None of our employees is
represented by a collective bargaining agreement, nor have we experienced any
work stoppage. We consider our relations with our employees to be good.
 
LEGAL PROCEEDINGS
 
We are not a party to any material legal proceedings.

(1)  Potential realizable values are computed by multiplying the number of
     shares of common stock subject to a given option by the assumed initial
     public offering price of $8.00 per share, assuming that the aggregate stock
     value derived from that calculation compounds at the annual 5% or 10% rate
     shown in the table for the entire ten-year term of the option and
     subtracting from that result the aggregate option exercise price. The 5%
     and 10% assumed annual rates of stock appreciation are mandated by the
     rules of the SEC and do not reflect our estimate or projection of future
     stock price growth.
 
(2)  These options were issued under our 1995 Management Stock Option Plan and
     our 1999 Equity Incentive Plan. Vesting and exercise terms are as follows:
     (a) the options granted in April 2000 vest monthly over a 30-month period
     and (b) the options granted in August 2000 vest monthly over a 24- or
     36-month period.
 
(3)  Based on an aggregate of 2,323,769 shares subject to options granted to our
     employees (not counting grants to non-employees) in the year ended December
     31, 2000, including options granted to the named executive officers.
 
(4)  Options were granted at an exercise price equal to the fair market value of
     our common stock, as determined by the Board of Directors at the date of
     the grant.

(1)  Some of the shares are immediately exercisable; however, the shares
     purchasable under such options are subject to repurchase by us at the
     original exercise price paid per share upon the optionee's cessation of
     service prior to the vesting of such shares. The shares listed as
     exercisable are those shares which are unexercised for which we no longer
     have a right of repurchase if the option is exercised by the holder;
     similarly, the shares listed as unexercisable include those shares over
     which we have a right of repurchase if the option is exercised by the
     holder.
 
(2)  Based on the fair market value of our common stock at year ended December
     31, 2000 ($3.20 per share, as determined by our Board of Directors), less
     the exercise price payable for such shares.
 
(3)  Diane Snedden, Mr. Asher's ex-wife, has the right to receive 128,165 shares
     upon the exercise of vested options pursuant to a divorce agreement and any
     and all proceeds from the sale thereof.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
Our Compensation Committee consists of Mr. Dotzler, Dr. Dunn and Mr. Younger.
None of these individuals is or has been an officer or employee of Omnicell. No
member of the Compensation Committee serves as a member of our board of
directors or compensation committee of any entity that has one or more executive
officers serving as a member of our Board of Directors.
 
STOCK PLANS
 
1992 EQUITY INCENTIVE PLAN AND 1995 MANAGEMENT STOCK OPTION PLAN
 
Our 1992 Equity Incentive Plan and 1995 Management Stock Option Plan
(collectively, the Incentive Plans) were adopted by our Board of Directors in
October 1992 and December 1995, respectively. There are currently 3,604,556
shares of common stock authorized for issuance under the Incentive Plans.
 
The Incentive Plans provide for the grant of incentive stock options under the
Internal Revenue Code of 1986, as amended (the Code), to employees and
nonstatutory stock options, restricted stock purchase awards and stock bonuses
to employees, directors and consultants. The Incentive Plans are administered by
our Board of Directors or a committee appointed by the Board of Directors that
determines recipients and types of awards to be granted, including the exercise
price, number of shares subject to the award and the exercisability thereof.
 
The term of stock options granted under the Incentive Plans generally may not
exceed 10 years. The exercise price of options granted under the Incentive Plans
are determined by our Board of Directors, provided that the exercise price for
an incentive stock option cannot be less than 100% of the fair market value of
our common stock on the date of the option grant and the exercise price for a
nonstatutory stock option cannot be less than 85% of the fair market value of
our common stock on the date of option grant. Options granted under the
Incentive Plans vest at the rate specified in the applicable option agreement.
No incentive stock option may be transferred by the optionee other than
 
                                       53
<Page>
by will, beneficiary designation or the laws of descent or distribution or, in
certain limited instances, pursuant to a qualified domestic relations order. Our
Board of Directors may grant a nonstatutory stock option that is transferable.
An optionee whose relationship with us or any related corporation ceases for any
reason, other than by death or permanent and total disability, may exercise
options in the three-month period following such cessation, unless such options
terminate or expire sooner or later by their terms. Options may be exercised for
up to twelve months after an optionee's relationship with us and our affiliates
ceases due to death or disability, unless such options expire sooner or later by
their terms.
 
No incentive stock option may be granted to any person who, at the time of the
grant, owns, or is deemed to own, stock possessing more than 10% of the total
combined voting power of Omnicell or any of our affiliates, unless the option
exercise price is at least 110% of the fair market value of the stock subject to
the option on the date of grant and the term of the option does not exceed five
years from the date of grant. The aggregate fair market value, determined at the
time of grant, of the shares of common stock with respect to which incentive
stock options are exercisable for the first time by an optionee and its
affiliates during any calendar year under all of our plans may not exceed
$100,000.
 
Shares subject to options that have expired or otherwise terminated without
having been exercised in full, or vested in the case of restricted stock awards,
will again become available for the grant of awards under the Incentive Plans.
 
Our Board of Directors has the authority to reprice outstanding options and to
offer optionees the opportunity to replace outstanding options with new options
for the same or a different number of shares.
 
We may grant restricted stock awards under the Incentive Plans that are subject
to a repurchase option by us in accordance with a vesting schedule and at a
price determined by our Board of Directors. Restricted stock purchases must be
at a price equal to at least 85% of the stock's fair market value on the award
date, but stock bonuses may be awarded in consideration of past services without
a purchase payment. Rights under a stock bonus or restricted stock purchase
agreement may not be transferred other than by will, the laws of descent and
distribution or a qualified domestic relations order while the stock awarded
pursuant to such an agreement remains subject to the agreement.
 
Under certain changes in control of Omnicell including a dissolution,
liquidation or sale of substantially all of our assets, a merger or
consolidation in which we are not the surviving corporation, or a reverse merger
in which we are the surviving corporation but the shares of common stock
outstanding immediately preceding the merger are converted by virtue of the
merger into other property, whether securities, cash or otherwise, then to the
extent permitted by applicable law, any surviving corporation will assume any
stock awards, including stock options, outstanding under the Incentive Plans or
substitute similar stock awards, or such stock awards under the Incentive Plans
will continue in full force and effect. In the event any surviving corporation
refuses to assume or continue such stock awards, or to substitute similar stock
awards for those outstanding under the Incentive Plans, then the stock awards
held by participants whose service with us or the surviving corporation has not
terminated shall become fully vested and exercisable prior to the change in
control and any such stock awards are not exercised prior to the change in
control will terminate thereafter.
 
As of June 30, 2001, 1,795,111 shares of common stock had been issued upon the
exercise of options granted under the Incentive Plans, options to purchase
1,803,016 shares of common stock were outstanding at a weighted average exercise
price of $3.79 per share and 6,428 shares of common stock remained available for
future grant. The 1992 Equity Incentive Plan and the 1995 Management Stock
Option Plan will terminate in October 2002 and December 2005, respectively,
unless sooner terminated by our Board of Directors.

1997 EMPLOYEE STOCK PURCHASE PLAN
 
In March 1997, our Board of Directors approved the 1997 Employee Stock Purchase
Plan which was amended in September 1999 and in April 2000. The 1997 plan is
intended to qualify as an employee stock purchase plan within the meaning of
that term in Section 423 of the Code. Under the 1997 plan, our Board of
Directors may authorize participation by eligible employees, including officers,
in periodic offerings following the adoption of the 1997 plan. The offering
period for any offering will be no more than 27 months.
 
The 1997 plan, as amended in September 1999 and April 2000, authorizes the
issuance of 468,750 shares of common stock under the 1997 plan which amount is
increased each January 1 by the lesser of 312,500 or 1.5% of the number of
shares of common stock outstanding each January 1 beginning January 1, 2001 and
ending January 1, 2007. However, our Board of Directors has the authority to
designate a smaller number of shares by which the authorized number of shares of
common stock will be increased on each January 1.
 
Employees are eligible to participate if they are employed by Omnicell or an
affiliate of Omnicell designated by our Board of Directors and are regularly
employed at least 20 hours per week and five months per year. Employees who
participate in an offering can have up to 15% of their earnings withheld
pursuant to the 1997 plan and applied, on specified dates determined by the
Board of Directors, to the purchase of shares of common stock. The price of
common stock purchased under the 1997 plan will be equal to 85% of the lower of
the fair market value of the common stock on the commencement date of each
offering period or the relevant purchase date. Employees may end their
participation in the offering at any time during the offering period, and
participation ends automatically on termination of employment with Omnicell.
 
In the event of certain changes of control of Omnicell, our Board of Directors
has discretion to provide that each right to purchase common stock will be
assumed or an equivalent right substituted by the successor corporation, or our
Board of Directors may shorten the offering period and provide for all sums
collected by payroll deductions to be applied to purchase stock immediately
prior to the change in control. The 1997 plan will terminate when all shares
reserved for issuance under the 1997 plan have been issued or sooner at the the
discretion of our Board of Directors.
 
As of June 30, 2001, we had issued 470,271 shares of common stock under the 1997
plan and 44,680 shares remain available for future issuance.
 
1999 EQUITY INCENTIVE PLAN
 
Our 1999 Equity Incentive Plan was adopted by our Board of Directors in
September 1999 and amended in April 2000. The 1999 plan was established to
replace the Incentive Plans. The 1999 plan will terminate in September 2009,
unless sooner terminated by our Board of Directors.
 
The 1999 plan provides for the grant of incentive stock options under Code
Section 422 to employees, including officers and employee-directors, and
nonstatutory stock options, restricted stock purchase awards and stock bonuses
to employees, directors and consultants. The 1999 plan is administered by our
Board of Directors or a committee appointed by the Board that determines
recipients and the terms and types of awards to be granted, including the
exercise price, number of shares subject to the award and the exercisability
thereof.
 
Stock option grants under the 1999 plan are made pursuant to an option
agreement. The term of stock options granted under the 1999 plan generally may
not exceed 10 years. The exercise price of options granted under the 1999 plan
is determined by our Board of Directors, provided that the exercise price for an
incentive stock option cannot be less than 100% of the fair market value of the
common stock on the date of the option grant and the exercise price for a
nonstatutory stock option cannot be less than 85% of the fair market value of
the common stock on the date of the option grant.
 
                                       55
<Page>
Options granted under the 1999 plan vest at the rate specified in the option
agreement. No incentive stock options may be transferred by the optionee other
than by will, beneficiary designation or the laws of descent and distribution
or, in certain limited instances, pursuant to a qualified domestic relations
order. Our Board of Directors may grant a nonstatutory stock option that is
transferable. An optionee whose relationship with us or our affiliates ceases
for any reason may exercise options in the three-month period following such
cessation, unless such options terminate or expire sooner or later by their
terms. Unless the options expire sooner or later by their terms, options may be
exercised for up to twelve months after an optionee's relationship with us and
our affiliates ceases due to disability and for up to 18 months after an
optionee's relationship with us and our affiliates ceases due to death.
 
No incentive stock options may be granted to any person who, at the time of the
grant, owns, or is deemed to own, stock possessing more than 10% of the total
combined voting power of us or of our affiliates, unless the option exercise
price is at least 110% of the fair market value of the stock subject to the
option on the date of the grant, and the term of the option does not exceed five
years from the date of the grant. The aggregate fair market value, determined at
the time of the grant, of the shares of common stock with respect to which
incentive stock options are exercisable for the first time by an optionee during
any calendar year, under all such plans of ours and our affiliates, may not
exceed $100,000.
 
Under the 1999 plan, 3,125,000 shares of common stock are authorized for
issuance. Each January 1, beginning January 1, 2001 and ending on January 1,
2009, the number of shares of common stock authorized for issuance under the
1999 plan will be increased on each January 1 by the lesser of (i) 1,875,000
shares, or (ii) 5.5% of the number of shares of common stock outstanding on that
date. However, our Board of Directors has the authority to designate a smaller
number of shares by which the authorized number of shares of common stock will
be increased on each January 1.
 
Shares subject to stock awards that have expired or otherwise terminated without
having been exercised in full, or vested in the case of restricted stock awards,
shall again become available for the grant of awards under the 1999 plan. Shares
subject to stock awards issued under the 1999 plan that have expired or
otherwise terminated without having been exercised in full, or vested in the
case of restricted stock awards, shall also become available for the grant of
awards under the 1999 plan. Shares issued under the 1999 plan may be previously
unissued shares or reacquired shares bought on the market or otherwise.
 
Restricted stock purchase awards granted under the 1999 plan may be granted
pursuant to a repurchase option in our favor in accordance with a vesting
schedule and at a price determined by our Board of Directors. Restricted stock
purchases must be at a price equal to 85% of the stock's fair market value on
the award date, but stock bonuses may be awarded in consideration of past
services without a purchase payment. Rights under a stock bonus or restricted
stock purchase agreement may not be transferred other than by will, the laws of
descent and distribution or a qualified domestic relations order while the stock
awarded pursuant to such an agreement remains subject to the agreement.
 
Under certain changes in control of Omnicell including a dissolution,
liquidation or sale of substantially all of our assets, a merger or
consolidation in which we are not the surviving corporation, or a reverse merger
in which we are the surviving corporation but the shares of common stock
outstanding immediately preceding the merger are converted by virtue of the
merger into other property, whether securities, cash or otherwise, then to the
extent permitted by applicable law, any surviving corporation will assume any
stock awards, including stock options, outstanding under the 1999 plan or
substitute similar stock awards, or such stock awards under the 1999 plan will
continue in full force and effect. In the event any surviving corporation
refuses to assume or continue such stock awards, or to substitute similar stock
awards for those outstanding under the 1999 plan, then the stock awards held by
participants whose service with us or the surviving corporation has not
terminated shall become fully
 
                                       56
<Page>
vested and exercisable prior to the change in control and any such stock awards
that are not exercised prior to the change in control will terminate thereafter.
 
As of June 30, 2001, 151,692 shares of common stock had been issued upon
exercise of options granted under the 1999 plan. Options to purchase
1,930,981 shares of common stock were outstanding at a weighted average exercise
price of $4.46 per share and 988,426 shares of common stock remained available
for future grant. The 1999 plan will terminate in September 2009, unless sooner
terminated by our Board of Directors.
 
NON-EMPLOYEE DIRECTOR STOCK OPTION GRANTS
 
The 1999 plan provides for automatic stock option grants to non-employee
directors on our Board of Directors. After the offering, each person who is not
an employee of Omnicell who is elected or appointed to our Board of Directors
will be granted an initial grant on the date of his or her election or
appointment to purchase 25,000 shares of our common stock at the fair market
value of our common stock on that grant date. On the date of the offering,
non-employee directors of our Board who have not previously been granted options
to purchase our common stock will receive an initial stock option grant as if he
or she were first elected or appointed to our Board of Directors after the
offering. The non-employee directors become vested in each initial stock option
grant 1/36 after each month of service on our Board of Directors from the stock
option grant date so that the directors will become vested fully after
36 months of service on our Board of Directors after the grant.
 
After the offering, each person who is a non-employee director on the day after
each annual stockholders' meeting, shall, on that date, be granted an annual
stock option grant to purchase 6,250 shares of our common stock at the fair
market value of our common stock on that grant date. The non-employee directors
become vested in each annual stock option grant 1/12 after each month of service
on our Board from the stock option grant date so that the directors will become
vested fully after 12 months of service on our Board of Directors after the
grant.
 
The non-employee director stock options will have a maximum term of ten years
and generally must be exercised prior to the earliest of 18 months following the
death of the non-employee directors, 12 months from the termination of service
on our Board of Directors by the non-employee director due to a disability,
three months from the termination of the service of non-employee director for
any other reason, or the expiration of the original term of the stock options.
The stock options shall not be transferable except as otherwise provided in a
stock option agreement to the extent permitted by federal securities laws and
regulations. If there is a change of control as described above, the directors
will become fully vested in their unvested portion of their stock options and
the options will be exercisable for a period of the shorter of twelve months
following the termination of their service on our Board of Directors or the
original term of the stock options.
 
401(k) PLAN
 
In October 1993, we adopted a tax-qualified employee savings plan under
Section 401(k) of the Code covering our employees. Pursuant to the 401(k) plan,
eligible employees may elect to reduce their current compensation by up to the
lesser of 15% of their annual compensation or the statutorily prescribed annual
limit and have the amount of such reduction contributed to the 401(k) plan. In
addition, eligible employees may make rollover contributions to the 401(k) plan
from a tax-qualified retirement plan. The 401(k) plan is intended to qualify
under Section 401(a) of the Code, so that contributions by employees or us to
the 401(k) plan, and income earned on the 401(k) plan contributions, are not
taxable to employees until withdrawn from the 401(k) plan, and so that
contributions by us, if any, will be deductible by us when made. We do not
presently intend to make any matching or discretionary contributions.
 
                                       57

EMPLOYMENT ARRANGEMENTS
 
In December 1993, we entered into an employment agreement with Mr. Asher whereby
Mr. Asher agreed to serve as our President and Chief Executive Officer. The
agreement provides Mr. Asher with an annual base salary of at least $200,000, a
performance bonus of at least $50,000 and $1,000,000 of term life insurance, the
owner and beneficiary of which are to be designated by Mr. Asher. Pursuant to
Mr. Asher's employment agreement, he receives a cash bonus of $12,500 following
each of the first three quarters of a given calendar year, and an annual bonus
after the close of the fourth quarter of that calendar year. Mr. Asher's annual
bonus is based on Omnicell achieving certain business and financial goals and
Mr. Asher achieving certain individual objectives, all of which are determined
by the executive management team and approved by the Board of Directors. In the
event of termination without cause, Mr. Asher will be entitled to receive the
base salary amount then in effect plus $50,000 for one year following the date
of termination.
 
In February 1998 and in February 2000, our Board of Directors approved the
acceleration, under certain circumstances, of all prior stock options granted to
each officer under our equity incentive plans. Under this arrangement, the
unvested portion of each officer's stock options under our equity incentive
plans becomes fully-vested and exercisable if we are acquired and the officer is
terminated without cause, the principal place of performance of the officer's
responsibilities and duties is changed, or there is a material reduction in the
officer's responsibilities and duties.
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY
 
Section 145 of the Delaware General Corporation Law authorizes a court to award,
or a corporation's board of directors to grant, indemnity to directors and
officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities, including reimbursement for expenses
incurred, arising under the Securities Act.
 
As permitted by Delaware law, our Certificate of Incorporation, which will
become effective upon the closing of this offering, includes a provision that
eliminates the personal liability of our directors for monetary damages for
breach of fiduciary duty as a director, except for liability:
 
    - for any breach of the director's duty of loyalty to us or our
      stockholders;
 
    - for acts or omissions not in good faith or that involve intentional
      misconduct or a knowing violation of law;
 
    - under Section 174 of the Delaware law regarding unlawful dividends and
      stock purchases; or
 
    - for any transaction from which the director derived an improper personal
      benefit.
 
As permitted by Delaware law, our Certificate of Incorporation and/or our
Bylaws, which will become effective upon the closing of this offering, provide
that:
 
    - we are required to indemnify our directors and officers to the fullest
      extent permitted by Delaware law, so long as such person acted in good
      faith and in a manner the person reasonably believed to be in or not
      opposed to the best interests of Omnicell, and with respect to any
      criminal action or proceeding, had no reasonable cause to believe the
      person's conduct was unlawful;
 
    - we are permitted to indemnify our other employees to the extent that we
      indemnify our officers and directors, unless otherwise required by law,
      our Certificate of Incorporation, our Bylaws or agreements;
 
    - we are required to advance expenses, as incurred, to our directors and
      officers in connection with a legal proceeding to the fullest extent
      permitted by Delaware law, subject to certain very limited exceptions; and
 
    - the rights conferred in our Bylaws are not exclusive.
 
                                       58
<Page>
Prior to the closing of this offering, we intend to enter into indemnity
agreements with each of our current directors and officers to give such
directors and officers additional contractual assurances regarding the scope of
the indemnification set forth in our Certificate of Incorporation and our Bylaws
and to provide additional procedural protections. At present, there is no
pending litigation or proceeding involving any of our directors, officers or
employees regarding which indemnification is sought, nor are we aware of any
threatened litigation that may result in claims for indemnification.

                           RELATED PARTY TRANSACTIONS
 
Pursuant to his employment agreement, in December 1993, we loaned Mr. Asher an
aggregate of $200,000 with an interest rate of 4% per year for the purchase of
92,165 shares of Series D Preferred Stock. The purchase price of $2.17 per share
was equal to the fair market value of the shares at the time of the sale. Twenty
percent of this loan matured each year beginning on January 1, 1995 and was
forgiven at such time so long as Mr. Asher remained employed by us. This loan
has been completely forgiven.
 
Pursuant to the Series E Preferred Stock Purchase Agreements dated December 22,
1993, the purchasers therein agreed to vote their shares to elect to our Board
of Directors a designated representative of Medicus Venture Partners 1993.
Medicus' right to elect a representative to our Board of Directors expires
following the completion of this offering. Mr. Dotzler has been the designated
representative thereunder.
 
We entered into a Stock Purchase Agreement with Sun Healthcare, dated June 7,
1996, for 1,802,000 shares of Series I Preferred Stock. In July 1996, the
non-voting Series I Preferred Stock was converted into voting Series J Preferred
Stock on a one-for-one basis.
 
In the years ended December 31, 1998, 1999 and 2000, we recorded revenues of
$9.9 million, $5.1 million and $1.9 million, from sales to Sun Healthcare,
representing approximately 20.5%, 9.3% and 2.7% of our revenues, respectively,
for the year. Sun Healthcare earned a cash rebate of $0.4 million for purchases
made from us during the year ended December 31, 1998.
 
In January 1999, Sun Healthcare exercised its right to have us redeem all of its
Series J Preferred Stock on a quarterly basis over the succeeding ten quarters.
During 1999 and 2000, we redeemed 1,081,200 shares of Series J Preferred Stock
at an approximate price per share of $14.03 for an aggregate redemption amount
of approximately $15.2 million. In addition, we paid Sun Healthcare accrued
interest on the Series J Preferred Stock of approximately $2.7 million. These
redemptions and interest payments were paid for with cash of $11.6 million and
the balance was paid for by offsetting Sun Healthcare's outstanding accounts
receivable balances of $6.3 million. We were not obligated to make the four
quarterly redemption payments of $2.5 million each that otherwise would have
been due in September 2000, December 2000, March 2001 and June 2001 because we
did not meet certain balance sheet tests under California law. Upon the closing
of this offering, we intend to make such redemption payments.
 
Pursuant to the terms of the Series K Stock Purchase Agreement, dated January
20, 2000, we agreed to nominate and use our best efforts to elect the designated
representative of ABS Capital Partners to our Board of Directors. ABS's right to
elect a representative to our Board of Directors expires following the
completion of this offering. Mr. Stobo is the current designated representative
of ABS Capital Partners.
 
In April, May, August, September, October and November 2000, we made loans to
the following executive officers to exercise stock options:

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
Upon the closing of this offering, we will be authorized to issue 50,000,000
shares of common stock, $.001 par value, and 5,000,000 shares of undesignated
preferred stock, $.001 par value. As of June 30, 2001, there were 14,678,920
shares of common stock outstanding held of record by approximately 580
stockholders, treating all outstanding preferred stock, other than 720,800
shares of our Series J Preferred Stock, on an as converted basis.
 
COMMON STOCK
 
The issued and outstanding shares of common stock are, and the shares of common
stock being offered by us hereby will be upon payment therefor, validly issued,
fully paid and nonassessable. Subject to the prior rights of the holders of any
preferred stock, the holders of outstanding shares of common stock are entitled
to receive dividends out of assets legally available therefor at such times and
in such amounts as the Board of Directors may from time to time determine. The
shares of common stock are neither redeemable nor convertible and the holders
thereof have no preemptive or subscription rights to purchase any of our
securities. Upon liquidation, dissolution or winding up of Omnicell, the holders
of common stock are entitled to receive pro rata our assets which are legally
available for distribution, after payment of all debts and other liabilities and
subject to the prior rights of any holders of any preferred stock then
outstanding. Each outstanding share of common stock is entitled to one vote on
all matters submitted to a vote of stockholders and has cumulative voting rights
with respect to the election of directors.
 
WARRANTS
 
As of June 30, 2001, there were outstanding warrants to purchase an aggregate of
11,521 shares of common stock at an exercise price of $1.74 per share, an
aggregate of 14,246 shares of common stock at an exercise price of $9.84 per
share, an aggregate of 44,373 shares of common stock at an exercise price of
$5.88 per share, and an aggregate of 33,276 shares of common stock at an
exercise price of $4.70. Warrants to purchase an aggregate of 61,830 shares of
common stock expire three years from the effective date of this offering, an
aggregate of 8,310 shares of common stock expire on July 7, 2005 and an
aggregate of 33,276 shares of common stock expire on December 31, 2005.
 
PREFERRED STOCK
 
Upon the closing of this offering, (i) all outstanding shares of convertible
preferred stock (except the Series J Preferred Stock) will be converted into
shares of common stock, provided that the price per share to the public is not
less than $8.00 and the aggregate price to the public is not less than
$25,000,000, in each case prior to the deduction of underwriter commissions and
offering expenses and (ii) 720,800 shares of Series J Preferred Stock will be
redeemed. Outstanding shares of the Series J Preferred Stock are currently being
redeemed at $14.03274 per share on a quarterly basis spread out in ten equal
quarterly installments beginning on March 8, 1999. The first six payments have
been made. Since September 2000, the three quarterly redemption payments of
$2.5 million each that were due in September 2000, December 2000 and March 2001,
have not been made as we were not obligated to make them because we did not meet
certain balance sheet tests under California law. The unredeemed balance of the
Series J Preferred Stock accrues interest at 9.5% per year. Effective upon the
closing of this offering, we will be authorized to issue 5,000,000 shares of
undesignated preferred stock. The Board of Directors will have the authority to
issue the preferred stock in one or more series and to fix the price, rights,
preferences, privileges and restrictions thereof, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
a series or the designation of such series, without any further
 
                                       63
<Page>
vote or action by our stockholders. The issuance of preferred stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of delaying, deferring or
preventing a change in control of Omnicell without further action by the
stockholders and may adversely affect the market price of the common stock and
the voting and other rights of the holders of common stock. We have no current
plans to issue any shares of preferred stock.
 
REGISTRATION RIGHTS
 
The holders of approximately 11,375,458 shares of common stock, as of June 30,
2001, and their permitted transferees are entitled to certain rights with
respect to the registration of these shares under the Securities Act. Under the
terms of agreements between us and the holders, the holders of at least 40% of
these shares may require, on two occasions, that we use our best efforts to
register these shares for public resale. The holders of these shares may not
exercise this right until four months after the effective date of this offering.
In addition, if we propose to register any of our securities under the
Securities Act, either for our own account or for the account of other security
holders exercising registration rights, the holders are entitled to notice of
such registration and are entitled to include shares of such common stock
therein. The holders of these shares may also require us on no more than four
occasions to register all or a portion of these shares on Form S-3 under the
Securities Act when use of such form becomes available to us. All such
registration rights are subject to conditions and limitations, including the
right of the underwriters of an offering to limit the number of shares to be
included in such registration. If such holders, by exercising their demand
registration rights, cause a large number of securities to be registered and
sold in the public market, such sales could have an adverse effect on the market
price for our common stock. If we were to initiate a registration and include
shares held by such holders pursuant to the exercise of their piggyback
registration rights, such sales may have an adverse effect on our ability to
raise capital.
 
ANTI-TAKEOVER PROVISIONS
 
DELAWARE LAW
 
Upon the closing of this offering, we will be subject to the provisions of
Section 203 of the Delaware General Corporation Law. In general, the statute
prohibits a publicly held Delaware corporation from engaging in any business
combination with any interested stockholder for a period of three years
following the date that the stockholder became an interested stockholder unless:
 
    - prior to the date, the board of directors of the corporation approved
      either the business combination or the transaction that resulted in the
      stockholder becoming an interested stockholder;
 
    - upon consummation of the transaction that resulted in the stockholder's
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transaction commenced, excluding those shares owned by persons who are
      directors and also officers, and employee stock plans in which employee
      participants do not have the right to determine confidentially whether
      shares held subject to the plan will be tendered in a tender or exchange
      offer; or
 
    - on or subsequent to the date, the business combination is approved by the
      board of directors and authorized at an annual or special meeting of
      stockholders, and not by written consent, by the affirmative vote of at
      least two-thirds of the outstanding voting stock that is not owned by the
      interested stockholder.
 
Section 203 defines "business combination" to include:
 
    - any merger or consolidation involving the corporation and the interested
      stockholder;
 
                                       64
<Page>
    - any sale, transfer, pledge or other disposition involving the interested
      stockholder of 10% or more of the assets of the corporation;
 
    - subject to exceptions, any transaction that results in the issuance or
      transfer by the corporation of any stock of the corporation to the
      interested stockholder; or
 
    - the receipt by the interested stockholder of the benefit of any loans,
      advances, guarantees, pledges or other financial benefits provided by or
      through the corporation.
 
In general, Section 203 defines an interested stockholder as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by the entity or person.
 
CHARTER AND BYLAW PROVISIONS
 
Our Certificate of Incorporation and Bylaws include a number of provisions that
may have the effect of deterring or impeding hostile takeovers or changes of
control or management. These provisions include:
 
    - our Board of Directors is classified into three classes of directors with
      staggered three-year terms;
 
    - the authority of our Board of Directors to issue up to 5,000,000 shares of
      preferred stock and to determine the price and the rights, preferences and
      privileges of these shares, without stockholder approval;
 
    - all stockholder action must be effected at a duly called meeting of
      stockholders and not by written consent; and
 
    - the elimination of cumulative voting.
 
Such provisions may have the effect of delaying or preventing a change of
control.
 
Our Certificate of Incorporation and Bylaws provide that we will indemnify
executive officers and directors against losses that they may incur in
investigations and legal proceedings resulting from their services to us, which
may include services in connection with takeover defense measures. Such
provisions may have the effect of preventing changes in our management.
 
OPTION ACCELERATION
 
In February 1998, February 2000 and March 2001 our Board of Directors approved
resolutions providing that the unvested portion of each officer's stock options
under our equity incentive plans becomes fully vested and exercisable if we are
acquired and the officer is thereafter terminated without cause, forced to
change the principal place of performance of the officer's responsibilities and
duties, or placed in a position with a material reduction in the officer's
responsibilities and duties.
 
TRANSFER AGENT AND REGISTRAR
 
The transfer agent and registrar for our common stock is Equiserve.
 
NATIONAL MARKET LISTING
 
We have applied for listing of our common stock on the Nasdaq National Market
under the symbol "OMCL."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
Prior to this offering, there has been no public market for our common stock.
Future sales of substantial amounts of our common stock in the public market
could adversely affect prevailing market prices from time to time. For a period
of 180 days or more following this offering substantial amounts of our common
stock will not be freely tradable due to contractual and legal restrictions as
described below. Sales of substantial amounts of our common stock in the public
market after these restrictions lapse could depress the prevailing market price
and limit our ability to raise equity capital in the future.
 
Upon the closing of this offering and based on shares outstanding as of
June 30, 2001, we will have an aggregate of 20,678,920 shares of common stock
outstanding, assuming no exercise of the underwriters' over-allotment option and
no exercise of outstanding options or warrants. Of the outstanding shares, the
shares sold in this offering will be freely tradable, except that any shares
held by our "affiliates", as that term is defined in Rule 144 promulgated under
the Securities Act, may only be sold in compliance with the limitations
described below. The remaining shares of common stock held by existing
stockholders will be deemed restricted securities as defined under Rule 144.
Restricted securities may be sold in the public market only if registered or if
they qualify for an exemption from registration under Rules 144, 144(k) or 701
promulgated under the Securities Act, which are summarized below. In accordance
with the lock-up agreements described below and subject to the provisions of
Rules 144, 144(k) and 701 and a right of repurchase in favor of us applicable to
some of our common stock, additional shares will be available for sale in the
public market at the following times:

The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares of common stock offered hereby are subject
to certain conditions precedent and that the underwriters will purchase all
shares of the common stock offered hereby, other than those covered by the
over-allotment option described below, if any of these shares are purchased. In
addition, the underwriting agreement provides that, in the event of a default by
an underwriter, in certain circumstances the purchase commitments of
non-defaulting underwriters may be increased or the underwriting agreement may
be terminated.
 
The underwriters propose to offer the shares of common stock to the public at
the public offering price set forth on the cover page of this prospectus and to
dealers at a price that represents a concession not in excess of $
      per share under the public offering price. The underwriters may allow, and
these dealers may re-allow, a concession of not more than $               per
share to certain other dealers. After the initial public offering,
representatives of the underwriters may change the offering price and other
selling terms.
 
We have granted to the underwriters an option, exercisable not later than 30
days after the date of this prospectus, to purchase up to 900,000 additional
shares of common stock at the public offering price, less the underwriting
discounts set forth on the cover page of this prospectus. The underwriters may
exercise such option solely to cover over-allotments, if any, made in connection
with this offering. To the extent that the underwriters exercise this option,
each underwriter will become obligated, subject to conditions, to purchase
approximately the same percentage of additional shares of common stock as the
number of shares of common stock to be purchased by it in the above table bears
to the total number of shares of common stock offered hereby. We will be
obligated, pursuant to the option, to sell these additional shares of common
stock to the underwriters to the extent the option is exercised. If any
additional shares of common stock are purchased, the underwriters will offer the
additional shares on the same terms as those on which the other shares are being
offered.
 
The underwriting fee is equal to the public offering price per share of common
stock less the amount paid by the underwriters to us per share of common stock.
The underwriting fee is currently expected to be approximately   % of the
initial public offering price. We have agreed to pay the underwriters the
following fees, assuming either no exercise or full exercise by the underwriters
of the underwriters' over-allotment option:

In addition, we estimate that our share of the total expenses of this offering,
excluding underwriting discounts and commissions, will be approximately
$         .
 
We have agreed to indemnify the underwriters against some specified types of
liabilities, including liabilities under the Securities Act, and to contribute
to payments the underwriters may be required to make in respect of any of these
liabilities.
 
Each of our officers and directors, and substantially all of our stockholders
and holders of options and warrants to purchase our stock, have agreed not to
offer, sell, contract to sell or otherwise dispose of, or enter into any
transaction that is designed to, or could be expected to, result in the
disposition of any shares of our common stock or other securities convertible
into or exchangeable or exercisable for shares of our common stock or
derivatives of our common stock owned by these persons prior to this offering or
common stock issuable upon exercise of options or warrants held by these persons
for a period of 180 days after the effective date of the registration statement
of which this prospectus is a part without the prior written consent of U.S.
Bancorp Piper Jaffray. This consent may be given at any time without public
notice. We have entered into a similar agreement with the representatives of the
underwriters. There are no agreements between the representatives and any of our
stockholders or affiliates releasing them from these lock-up agreements prior to
the expiration of the 180-day period.
 
The representatives of the underwriters have advised us that the underwriters do
not intend to confirm sales to any account over which they exercise
discretionary authority.
 
In order to facilitate the offering of our common stock, the underwriters may
engage in transactions that stabilize, maintain or otherwise affect the market
price of our common stock. Specifically, the underwriters may make short sales
of our common stock and may purchase our common stock on the open market to
cover positions created by short sales. Short sales involve the sale by the
underwriters of a greater number of shares than they are required to purchase in
the offering. "Covered" short sales are sales made in an amount not greater than
the underwriters' over-allotment option to purchase additional shares in the
offering. The underwriters may close out any covered short position by either
exercising their over-allotment option or purchasing shares in the open market.
In determining the source of shares to close out the covered short position, the
underwriters will consider, among other things, the price of shares available
for purchase in the open market as compared to the price at which they may
purchase shares through the over-allotment option. "Naked" short sales are sales
in excess of the over-allotment option. The underwriters must close out any
naked short position by purchasing shares in the open market. Similar to other
purchase transactions, the underwriters' purchases to cover the underwriting
syndicate short sales may have the effect of raising or maintaining the market
price of our common stock or preventing or retarding a decline in the market
price of our common stock. As a result, the price of our common stock may be
higher than the price that might otherwise exist in the open market. In
addition, the representatives, on behalf of the underwriters, may also reclaim
selling concessions allowed to an underwriter or dealer if the underwriting
syndicate repurchases shares distributed by that underwriter or dealer, which
may also maintain the market price of our common stock at a level above that
which might otherwise exist in the open market. These transactions may be
effected on the Nasdaq National Market or otherwise. The underwriters are not
required to engage in these activities and, if commenced, may end any of these
activities at any time.
 
At our request, the underwriters have reserved for sale, at the initial public
offering price, up to $5 million of our common stock for Bergen Brunswig. This
would represent 625,000 shares or approximately 10% of our common stock sold in
this offering at the midpoint of the offering range. Bergen Brunswig has agreed
that, if it purchases any shares of common stock in the offering, it will not
sell, transfer or otherwise dispose such shares for one year after the
completion of this offering. In addition, at our request, the underwriters have
reserved for sale, at the initial public offering price, up to 300,000 shares or
5% of our common stock being sold in this offering for our vendors, employees,
family members of employees, customers and other third parties. The number of
shares of our common
 
                                       69
<Page>
stock available for sale to the general public will be reduced to the extent
these reserved shares are purchased. Any reserved shares that are not purchased
by these persons will be offered by the underwriters to the general public on
the same basis as the other shares in this offering.
 
PRICING OF THE OFFERING
 
Prior to this offering, there has been no public market for our common stock.
Consequently, the initial public offering price for our common stock has been
determined by negotiations among us and the representatives of the underwriters.
Among the primary factors considered in determining the initial public offering
price were:
 
    - prevailing market conditions;
 
    - our results of operations in recent periods;
 
    - the present stage of our development;
 
    - the market capitalization and stage of development of the other companies
      that we and the representatives of the underwriters believe to be
      comparable to our business; and
 
    - estimates of our business potential.
 

                                 LEGAL MATTERS
 
The validity of the shares of common stock offered hereby will be passed upon
for us by Cooley Godward LLP, Palo Alto, California. Certain legal matters in
connection with this offering will be passed upon for the underwriters by
Preston Gates & Ellis LLP, Seattle, Washington.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Omnicell, Inc.
 
We have audited the accompanying consolidated balance sheets of Omnicell, Inc.
as of December 31, 1999 and 2000, and the related consolidated statements of
operations, redeemable convertible preferred stock and stockholders' equity (net
capital deficiency), and cash flows for each of the three years in the period
ended December 31, 2000. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Omnicell, Inc. at
December 31, 1999 and 2000, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
2000, in conformity with accounting principles generally accepted in the United
States.
 
As discussed in Note 18 to the consolidated financial statements, the
consolidated balance sheets, statements of operations, redeemable convertible
preferred stock and stockholders' equity (net capital deficiency), and cash
flows for each of the three years in the period ended December 31, 2000 have
been restated.

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF THE COMPANY
 
The Company was incorporated in the State of California in September 1992 under
the name OmniCell Technologies, Inc. In September 1999, the Company changed its
name to Omnicell.com and intends to reincorporate in Delaware and change its
name to Omnicell, Inc. immediately prior to the completion of the offering. All
references in these financial statements will be to "Omnicell, Inc." or the
"Company."
 
The Company provides an integrated suite of clinical infrastructure and workflow
automation solutions for healthcare facilities. These solutions include
automation systems, clinical reference tools, an Internet-based procurement
application and decision support capabilities. The Company sells and leases its
products and related services to a wide range of healthcare facilities such as
hospitals, integrated delivery networks and alternate care facilities, which
include nursing homes, outpatient surgery centers, catheterization labs and
clinics.
 
FUTURE FINANCING
 
The Company may be required to raise additional capital through the public
equity market, private financings, collaborative arrangements and debt.
Additional financing may not be available to the Company on favorable terms, if
at all. If the Company is unable to obtain financing, or to obtain it on
acceptable terms, it may be unable to execute the business plan.
 
PRINCIPLES OF CONSOLIDATION
 
The consolidated financial statements include the Company and its wholly owned
subsidiaries, Omnicell HealthCare Canada, Inc. and Omnicell Europe SARL. All
significant intercompany accounts and transactions are eliminated in
consolidation.
 
INTERIM FINANCIAL INFORMATION
 
The interim financial information at March 31, 2001 and for the three months
ended March 31, 2000 and 2001 is unaudited but, in the opinion of management,
has been prepared on the same basis as the annual financial statements and
includes all adjustments (consisting only of normal recurring adjustments) that
the Company considers necessary for a fair presentation of its financial
position at such date and its operating results and cash flows for those
periods. Results for the interim period are not necessarily indicative of the
results to be expected for the entire year, or any future period.
 
USE OF ESTIMATES
 
The preparation of consolidated financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that materially affect the amounts
reported in the consolidated financial statements. Actual results could differ
from these estimates.

  (INFORMATION AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 2000 AND 2001 IS
                                   UNAUDITED)
 
NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION
 
Revenues are derived primarily from sales of pharmacy and supply systems and
subsequent service agreements. The Company markets these systems for sale or for
lease. Pharmacy and supply system sales, which are accounted for in accordance
with American Institute of Certified Public Accountant's Statement of
Position 97-2 (SOP 97-2), "Software Revenue Recognition," are recognized upon
completion of Omnicell's installation obligation at the customer's site.
Revenues from leasing arrangements are recognized in accordance with Statement
of Financial Accounting Standards (SFAS) No. 13, "Accounting for Leases," upon
completion of the Company's installation obligation and commencement of the
noncancelable lease term. Post-installation technical support, such as phone
support, on-site service, parts and access to software upgrades, is provided by
the Company under separate annual service agreements. Revenues on service
agreements are recognized ratably over the related service contract period.
Deferred revenue represents amounts received under service agreements for which
the services have not yet been performed and upfront fees received from certain
distributors of our pharmacy and supply systems. These upfront fees are
recognized ratably over the period of the distribution agreement. Deferred gross
profit represents the profit to be earned by the Company, exclusive of
installation costs, on pharmacy and supply systems sales for which customer
acceptance has occurred but the Company's installation obligation has not yet
been fulfilled. Installation costs are recorded to cost of goods sold when
incurred.
 
Revenues from the Company's Internet-based procurement application, introduced
in 1999, are recognized ratably over the subscription period. Internet-based
procurement application revenues were not significant in the years ended
December 31, 1999 and 2000, and are included in service and other revenues.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
The Company has determined the estimated fair value of financial instruments.
The amounts reported for cash and cash equivalents, accounts receivable, notes
receivable from stockholders, accounts payable, and accrued expenses approximate
fair value because of their short maturities. Short-term investments are
reported at their estimated fair value based on quoted market prices of
comparable instruments. Based on borrowing rates currently available to the
Company for loans with similar terms, the carrying value of its debt obligations
approximates fair value.
 
CASH EQUIVALENTS
 
The Company considers all highly liquid debt instruments with original
maturities of 90 days or less to be cash equivalents.
 
CONCENTRATIONS OF CREDIT RISK AND SIGNIFICANT CUSTOMERS
 
Financial instruments that potentially subject the Company to concentrations of
credit risk consist principally of cash equivalents, investments, accounts
receivable and notes receivable from stockholders. Cash equivalents consist
primarily of money market funds and commercial debt securities and are held
primarily with two financial institutions. By policy, the Company limits the
amounts invested in any type

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
of instrument for investments other than U.S. government treasury instruments.
The Company places its investments for safekeeping with an insured creditworthy
financial institution.
 
The Company sells and leases its products and services primarily to hospitals
and other healthcare facilities throughout the United States. The majority of
leases originated by the Company are sold to unaffiliated finance companies (see
Note 3). To date, the Company has had no significant credit losses.
 
One customer accounted for 20.5% of revenues in 1998. No one customer accounted
for over 10.0% of revenues in 1999 or 2000.
 
One customer accounted for 11.0% of accounts receivable at December 31, 1999. A
different customer accounted for 11.0% of accounts receivable at December 31,
2000.
 
The majority of net revenues are generated from customers in North America
totaling 99% of total net revenues in 1998, 1999 and 2000.
 
SHORT-TERM INVESTMENTS
 
Short-term investments consist primarily of highly liquid debt instruments
purchased with original maturities of greater than 90 days but less than twelve
months. The Company classifies these securities as available-for-sale. The
differences between amortized cost and fair value, representing unrealized
holding gains or losses, are recorded as a separate component of stockholders'
equity until realized. Any gains and losses on the sale of short-term
investments are determined on a specific identification method, and such gains
and losses are reflected as a component of net interest income (expense). The
Company has not experienced any significant gains or losses on its investments
to date.
 
INVENTORIES
 
Inventories are stated at the lower of cost (utilizing standard costs, which
approximate the first-in, first-out method) or market. The Company routinely
assesses its on-hand inventory for timely identification and measurement of
obsolete, slow-moving, or otherwise impaired inventory.
 
PROPERTY AND EQUIPMENT
 
Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation and amortization are computed using the straight-line
method over the estimated useful lives of the related assets, generally three to
five years. Leasehold improvements are amortized over the shorter of the lease
term or the estimated useful lives of the improvements, generally four to seven
years.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
The Company evaluates its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of such assets may
not be recoverable. Recoverability of assets to be held and used is measured by
a comparison of the carrying amount of any asset to future net cash flows
expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
the assets exceed the fair value of the assets. Assets to be disposed of are
reported at the lower of the carrying amount or fair value less costs to sell.
 
SOFTWARE DEVELOPMENT COSTS
 
Development costs related to software incorporated in the Company's pharmacy and
supply systems incurred subsequent to the establishment of technological
feasibility are capitalized and amortized over the estimated lives of the
related products. Technological feasibility is established upon completion of a
working model. At December 31, 2000, capitalized software development costs are
approximately $900,000. These costs will be amortized over a 3-year period upon
commercial introduction and are reported as a component of other assets. There
were no capitalized software development costs at December 31, 1999.
 
ADVERTISING EXPENSES
 
The Company expenses the costs of advertising as incurred. Advertising expenses
for the years ended December 31, 1998, 1999 and 2000 were approximately $11,000,
$628,000 and $1.2 million, respectively.
 
INTEGRATION EXPENSES
 
Integration expenses relate to expenses incurred to integrate the Sure-Med
product line (see Note 2) into the Company's operations. These expenses include
charges for employee severance costs, travel, training and relocation expenses.
 
STOCK-BASED COMPENSATION
 
Under SFAS No. 123, "Accounting for Stock-Based Compensation," the Company
accounts for stock-based awards to employees using the intrinsic value method
established by Accounting Principles Board Opinion No. 25 (APB 25), "Accounting
for Stock Issued to Employees." Thus, no compensation expense is recognized for
options granted with exercise prices equal to the fair value of the Company's
common stock on the date of grant.
 
INCOME TAXES
 
The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes." This statement prescribes the use of the
liability method whereby deferred tax assets and liabilities are determined
based on differences between financial reporting and tax bases of assets and
liabilities, and are measured using enacted tax rates and laws that will be in
effect when the differences are expected to reverse.
 
COMPREHENSIVE INCOME
 
In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 130, "Reporting Comprehensive Income," which establishes standards for
reporting and displaying comprehensive income and its components in financial
statements. The only items of other comprehensive income (loss) that the Company
currently reports are unrealized gains (losses) on short-term investments,

SEGMENT INFORMATION
 
The Company reports segments in accordance with SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information." SFAS No. 131 requires the
use of a management approach in identifying segments of an enterprise. Prior to
1999, the Company consisted of one operating segment: pharmacy and supply
systems. A second operating segment was created in the second half of 1999 with
the introduction of the Company's e-commerce business. The Company's chief
operating decision maker reviews information pertaining to reportable segments
to the operating income level. There are no significant intersegment sales or
transfers. Assets of the operating segments are not segregated and substantially
all of the Company's long-lived assets are located in the United States.
 

For the years ended December 31, 1999 and 2000, substantially all of the
Company's total revenues and gross profits were generated by the pharmacy and
supply systems operating segment. The Internet-based e-commerce business
operating segment generated less than one percent of consolidated revenues in
each of 1999 and 2000. The operating loss generated by the segment was
approximately $2.0 million and $10.3 million in 1999 and 2000, respectively,
excluding the $2.9 million restructuring charge recorded in 2000.

 
STOCK SPLIT
 
All common stock share and per share amounts have been restated to reflect a
1-for-1.6 reverse stock split.
 
NET INCOME (LOSS) PER SHARE
 
In accordance with SFAS No. 128, "Earnings Per Share," basic net income (loss)
per share is computed by dividing the net income (loss) applicable to common
stockholders for the period by the weighted average number of common shares
outstanding during the period, less shares subject to repurchase. Diluted net
income (loss) per share is computed by dividing the net income (loss) applicable
to common stockholders for the period by the weighted average number of common
and common equivalent shares outstanding during the period. Potentially dilutive
securities, composed of incremental common shares issuable upon the exercise of
stock options and warrants, and common shares issuable on conversion of
preferred stock, were excluded from historical diluted loss per share for the
years ended December 31, 1999 and 2000 because of their anti-dilutive effect.
The total number of shares excluded from the calculations of diluted net loss
per share for the years ended December 31, 1999 and 2000, was 8,072,388 and
14,386,937, respectively. The total number of shares excluded from the
calculations of diluted net loss per share for the three months ended March 31,
2000 and 2001 was 9,981,453 and 15,194,416, respectively.
 
Under the provisions of SAB No. 98, common shares issued for nominal
consideration, if any, would be included in the per share calculations as if
they were outstanding for all periods presented. No common shares have been
issued for nominal consideration.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  (INFORMATION AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 2000 AND 2001 IS

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
UNAUDITED PRO FORMA BALANCE SHEET
 
The unaudited pro forma balance sheet information at March 31, 2001 reflects the
assumed conversion of all of the Company's convertible preferred stock and a
convertible note upon completion of the offering by this prospectus. The
unaudited pro forma balance sheet also reflects the assumed redemption of
720,800 shares of redeemable convertible preferred stock at a price of $14.03
per share plus accrued interest thereon of $240,000. In addition, the unaudited
pro forma balance sheet assumes the $10.4 million redemption obligation will be
fulfilled using all of the Company's available cash and cash equivalents and
short-term investments of $7.7 million with the balance of $2.7 million redeemed
through the issuance of a short-term note payable to the stockholder.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
In March 2000, the Emerging Issues Task Force (EITF) published its consensus on
Issue No. 00-2, "Accounting for Web Site Development Costs." This EITF sets
forth guidance on whether to capitalize or expense certain development costs.
The Company has adopted EITF 00-2 effective January 1, 2000 and capitalized
$260,000 of Web site development costs in the year ended December 31, 2000.
These costs were written off as a part of the 2000 restructuring activities.
 
In March, 2000, the FASB issued Interpretation No. 44, "Accounting for Certain
Transactions Involving Stock Compensation," an interpretation of APB No. 25. The
Interpretation is applied prospectively to all new awards, modifications to
outstanding awards, and changes in employee status after July 1, 2000, with the
exception of the definition of employee and stock option repricings as to which
the effective date is December 15, 1998. The adoption of this Interpretation did
not have a significant effect on the Company's results of operations or
financial condition.
 
In December 1999, the Securities and Exchange Commission issued SAB No. 101,
"Revenue Recognition in Financial Statements." SAB No. 101 provides guidance on
the recognition, presentation and disclosure of revenue in financial statements.
The Company has adopted SAB No. 101 for all periods presented.
 
In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS No. 137 and No. 138,
which is effective for years beginning after June 15, 2000. SFAS No. 133, as
amended, will require the Company to recognize all derivatives on the balance
sheet at fair value. Gains or losses resulting from changes in the values of
those derivatives would be accounted for depending on the use of the derivative
and whether it qualifies for hedge accounting. SFAS No. 133 will be effective
for the Company's financial statements for the year ended December 31, 2001.
Management believes that this statement will not have a significant effect on
the Company's results of operations or financial condition.
 
NOTE 2.  SURE-MED ACQUISITION
 
Effective January 29, 1999, the Company acquired substantially all of the assets
together with certain specified liabilities and obligations of the Sure-Med
product line of Baxter Healthcare in a transaction accounted for as a purchase.
Baxter Healthcare designed, marketed and sold Sure-Med pharmacy systems to
hospitals and other healthcare facilities. The consolidated financial statements
include the operating results of Sure-Med from the date of acquisition.

NOTE 2.  SURE-MED ACQUISITION (CONTINUED)
The original purchase price of $15.1 million consisted of a cash payment of $2.0
million to Baxter Healthcare, a promissory note of $12.7 million, and $400,000
of related acquisition expenses. In December 1999, the purchase price was
adjusted downward by $6.4 million through a $1.6 million cash payment from
Baxter Healthcare to the Company and a $4.8 million reduction in the note
payable to Baxter Healthcare. The Company is obligated to repay the principal
amount of the promissory note in eight quarterly installments, commencing on
March 31, 2002, or earlier upon the closing of an initial public offering. The
promissory note bears interest at a rate of 8.0% through December 31, 2001, 9%
through December 31, 2002 and 10% through December 31, 2003. Interest is payable
quarterly, commencing on March 31, 1999. Upon the sale or issuance by Omnicell
of any shares of capital stock, excluding sales or issuances of common stock or
options under the Company's stock option and stock purchase plans and private
placements in any single year not exceeding 10.0% of its outstanding paid-in
capital, the Company is required to prepay the outstanding principal amount of
the promissory note plus accrued interest to the extent of 50.0% of the net
proceeds of such equity issuance. There is an exception that allows up to
$30 million of financing raised during 2000 to be excluded as long as 50.0% of
the proceeds shall be applied to redeeming the Series J preferred stock. See
Note 14.
 
The purchase price consideration was allocated to the acquired assets and
assumed liabilities based on fair values as follows (in thousands):

In the fourth quarter of 1999, after sales of the Sure-Med pharmacy systems were
determined to be substantially below original forecasts, the Company recorded a
$9.7 million charge to cost of revenues to reflect a writedown of Sure-Med
product line inventory to estimated net realizable value. In 1999, the Company
also recorded $785,000 of integration expenses associated with the integration
of the Company and Sure-Med engineering efforts, product lines, and marketing
efforts.
 
The Sure-Med acquisition was entered into with the expectation that significant
sales would be generated in 1999 and 2000. The actual sales for 1999 and 2000
were substantially below the levels anticipated in the Company's forecasts.
Product integration issues hindered the Company's sales force in its attempt to
sell the Sure-Med pharmacy systems. As a result, during the third quarter of
fiscal 2000, the Company significantly reduced its Sure-Med pharmacy systems
sales and marketing efforts. It also performed a SFAS 121 impairment analysis on
the remaining Sure-Med intangible assets and concluded that, based on estimated
negative future cash flows, the $182,000 net balance of its intangible assets
was impaired and was therefore written-off to expense.

NOTE 3.  LEASING ARRANGEMENTS (CONTINUED)
 
In 1999 and 2000, net sales-type lease receivables sold under these agreements
totaled approximately $22.3 million and $20.7 million, respectively. The Company
records revenue at an amount equal to the cash to be received from the leasing
company, which is equivalent to the net present value of the lease streams,
utilizing the implicit interest rate under its funding agreements. At December
31, 1999 and 2000, accounts receivable included approximately $2.7 million and
$1.5 million, respectively, due from the finance companies for lease receivables
sold.

No equipment was leased under capital leases at December 31, 1999 and 2000.
 
In August 1999, the Company completed a software license transaction with
Commerce One, Inc. Purchased software consists primarily of this software
licensed on a perpetual basis to enable customer use of the Company's
Internet-based procurement application. Maintenance and support will be provided
by the licensor at contractual annual rates. The Company will share with the
licensor a portion of the transaction fees collected, if any, from product
manufacturers when purchases are made from healthcare suppliers on the Company's
Internet-based procurement application.
 
In the third quarter of 2000, the Company wrote-off the $2.0 million remaining
balance of the MarketSite software license as part of the restructuring
activities.
 
NOTE 7.  OTHER ASSETS
 
In 1997, the Company provided a loan of $500,000 to a strategic partner that was
in a development stage. The note receivable bore interest at 8.5% and was due in
September 2000. The note receivable was automatically convertible to equity of
the corporation upon the closing of that entity's next financing of at least
$1,000,000 or upon default of payment, based on the unpaid principal balance and
accrued interest divided by the fair value price per share. In December 1998,
upon the closing of a financing by the corporation, the note was converted into
13,052 shares of its Series D convertible preferred stock. At December 31, 1999,
the Company determined that there was a permanent decline in the fair value of
this asset and recorded a valuation allowance of $550,000 against the entire
investment, including accrued interest.

NOTE 9.  RESTRUCTURING
 
The Company recorded restructuring costs of $2.9 million in the third quarter of
fiscal 2000 in connection with a strategic change in its e-commerce business to
concentrate primarily on its Internet-based procurement application. This
resulted in a workforce reduction of approximately 14 positions. The primary
components of the restructuring charge were $2.0 million related to a purchased
software license, $260,000 related to capitalized software engineering costs,
and $517,000 of employee severance costs. The total cash outlays related to
these charges were $404,000 in 2000. As of December 31, 2000, activities related
to this restructuring were completed.

NOTE 12.  CREDIT FACILITY
 
In January 2000, the Company entered into a credit facility with a bank. This
facility, as amended in August 2000, and January, May and June 2001 provides the
Company with advances of up to 80% of eligible receivables, as defined, up to
$10.0 million, and expires on June 30, 2002. This line of credit bears interest
at the prime rate plus 2.25%. The Company has pledged substantially all of its'
assets as collateral for this line of credit. The credit facility requires the
Company to comply with a tangible net deficit financial covenant and other
specified non-financial covenants. At December 31, 2000, the Company had no
borrowings under this credit facility, was eligible to borrow approximately
$4.4 million, and was in compliance with the covenants.
 
Under the terms of the credit facility, on December 31, 2000 the Company issued
to the bank a warrant to purchase 26,351 shares of its common stock at $9.50 per
share with conversion terms on an initial public offering similar to the
conversion terms for the Series K preferred stock (Note 15). The warrant expires
on December 31, 2005. The warrant will convert to a warrant to purchase 31,249
shares of common stock at $8.00 per share based on the Series K conversion
adjustment and the 1-for-1.6 reverse stock split. This warrant has been valued
at $78,000 using the Black-Scholes valuation method. This amount is included in
other assets and will be amortized through the credit line's expiration date.
 
NOTE 13.  LEASE COMMITMENTS
 
The Company leases its Palo Alto, California and Waukegan, Illinois offices and
manufacturing facilities under noncancelable operating leases. The leases expire
beginning January 2002 through June 2006. The Company has an option to renew the
Palo Alto manufacturing facility lease (expires June 2003) and Waukegan facility
lease (expires June 2006) for an additional five years. Rent expense for all
operating leases was $728,000 (net of sublease income of $64,000), $1,629,000
and $2,120,000 (net of sublease income of $286,000) for the years ended
December 31, 1998, 1999 and 2000, respectively.

NOTE 14.  REDEEMABLE CONVERTIBLE PREFERRED STOCK
 
In June 1996, the Company issued 1,802,000 shares of nonvoting Series I
redeemable convertible preferred stock to Sun Healthcare for $25,227,000 (net of
issuance costs of approximately $60,000) and authorized an equal number of
voting shares of Series J redeemable convertible preferred stock. The Series I
redeemable convertible preferred stock was converted into Series J redeemable
convertible preferred stock on a one-for-one basis in 1996.
 
At any time after December 31, 1998, the holders of the Series J redeemable
convertible preferred stock were entitled to require the Company to redeem for
cash the outstanding shares over 30 months at a per share price equal to the
original issue price (subject to adjustment for events of dilution) plus
interest at 9.5% per annum (accruing beginning on March 8, 1999).
 
In January 1999, Sun Healthcare exercised its right to redeem its 1,802,000
shares of Series J redeemable convertible preferred stock in ten equal quarterly
installments beginning in March 1999. Through December 31, 2000, the Company had
redeemed 1,081,200 shares of Series J redeemable convertible preferred stock
from Sun Healthcare for $15.2 million plus interest of $2.7 million. Cash of
$11.6 million was used to satisfy this redemption, with the balance of
$6.3 million paid by offsetting Sun Healthcare's outstanding accounts receivable
balances. All payments have been made except the three quarterly redemption
payments of $2.5 million each that were due in September 2000 and December 2000
and March 2001, which the Company was not obligated to make because the Company
did not meet certain balance sheet tests under California law. The Company will
no longer be subject to these restrictions of California law following its
reincorporation in Delaware.
 
Sun Healthcare has an accounts receivable balance of approximately $260,000 at
December 31, 2000. In the past the two parties have offset the Omnicell accounts
receivable balance with the redemption payments. At year end, the two parties
had not finalized any offsetting agreement.

NOTE 14.  REDEEMABLE CONVERTIBLE PREFERRED STOCK (CONTINUED)
 
Significant terms of the Series J redeemable convertible preferred stock are as
follows:
 
    - Conversion of the Series J preferred stock is automatic upon completion of
      an initial public offering. In addition to adjustments for events of
      dilution, if the Company completes an initial public offering at a price
      greater than $11.78 per share and less than $13.47 per share, the
      conversion price of the Series J preferred stock will be adjusted to
      $17.72 per share from the original purchase price of $22.4523 (as
      converted per the 1-for-1.6 reverse stock split). If the offering price is
      less than $11.78 per share, the conversion price of the Series J preferred
      stock will be adjusted to $16.8370 per share.
 
    - Series J preferred stock has voting rights equivalent to the number of
      shares of common stock into which it is convertible.
 
    - Dividends may be declared at the discretion of the Board of Directors and
      are noncumulative. To the extent declared, dividends of $1.12 per share,
      per annum for Series J preferred stock must be paid prior to any dividends
      on any other preferred stock or common stock. No such dividends have been
      declared or paid.
 
    - In the event of liquidation, dissolution, or winding up of the Company,
      prior to any other preferred stockholders, Series J stockholders shall
      receive $14.03 per share plus all declared but unpaid dividends. Upon
      completion of this distribution, the holders of the common stock will
      receive a pro rata distribution of any remaining assets of the Company. At
      December 31, 2000, the aggregate liquidation preference for redeemable
      convertible preferred stock was $10,113,000.
 
NOTE 15.  STOCKHOLDERS' EQUITY
 
CONVERTIBLE PREFERRED STOCK
 
During the first quarter of 2000, the Company designated and issued 3,010,528
shares of Series K convertible preferred stock at a price of $9.50 per share
subject to adjustment for events of dilution as described below. Net proceeds
were approximately $28.5 million.
 
Conversion of the Series K convertible preferred stock is automatic upon
completion of an initial public offering in excess of $25 million at an offering
price of not less than $8.00 per share. If the Company completes an initial
public offering at a price less than $33.78 per share, the conversion price of
the Series K convertible preferred stock will adjust to 45% of the initial
public offering price, but in no event will it adjust to less than $8.00 per
share. This means that if this offering is completed at a price less than $17.78
per share, the resulting conversion price of the Series K convertible preferred
stock will be $8.00 per share, and a total of 3,575,000 shares of common stock
will be issued on conversion of such preferred stock exclusive of adjustments
for events of dilution.

Significant terms of the convertible preferred stock are as follows:
 
    - Each share of Series A, B, C, D, E, G, H and K preferred stock is
      convertible into one share of common stock, and each share of Series F
      preferred stock is convertible into 1.107 shares of common stock (subject
      to adjustment for events of dilution). Each share will automatically
      convert upon an underwritten public offering of common stock meeting
      specified criteria.
 
    - Each share of convertible preferred stock has voting rights equivalent to
      the number of shares of common stock into which it is convertible. The
      holders of Series E preferred stock, voting together as a class, are
      entitled to elect one director of the Company. The holders of Series H
      preferred stock, voting together as a class, are also entitled to elect
      one director of the Company. The holders of Series K preferred stock,
      voting together as a class, are also entitled to elect one director of the
      Company.
 
    - Dividends may be declared at the discretion of the Board of Directors and

      $0.048, $0.085, $0.265, $0.49, $0.49, $0.29, and $0.76 per share, per
      annum for Series A, B, C, D, E, F, G, H and K preferred stock,
      respectively, must be paid prior to any dividends on common stock. No such
      dividends have been declared or paid.
 
    - In the event of liquidation, dissolution, or winding up of the Company,
      Series A, B, C, D, E, F, G, H and K stockholders shall receive, after
      required distributions to the redeemable convertible preferred
      stockholders, $0.25, $0.375, $0.60, $1.085, $3.30, $6.15, $6.15 and $3.68
      and $9.50 per share, respectively, plus all declared but unpaid dividends.

NOTE 15.  STOCKHOLDERS' EQUITY (CONTINUED)
CONVERTIBLE PREFERRED STOCK WARRANTS
 
In connection with a capital lease financing in 1994, the Company issued a
warrant to purchase 18,434 shares of Series D preferred stock at an exercise
price of $1.09 per share (or 11,521 shares of common stock as converted per the
1-for-1.6 reverse stock split at a price of $1.74 per share). The warrant
expires three years from the effective date of an initial public offering of the
Company's common stock. The value of the warrant was immaterial.
 
In connection with capital lease financings in 1995, the Company issued warrants
to purchase 8,130, 11,382 and 67,934 shares of Series F, G and H preferred stock
at $6.15, $6.15 and $3.68 per share, respectively (or 5,081, 7,113 and 42,121
shares of common stock as converted per the 1-for-1.6 reverse stock split at
prices of $9.84, $9.84 and $5.89 per share, respectively). The Series F and H
warrants expire three years from the effective date of an initial public
offering of the Company's common stock. The Series G warrant expires five years
from the effective date of an initial public offering of the Company's common
stock. The estimated value of these warrants remaining after amortization was
expensed in June 1996 when the repayments were made for the borrowings.
 
NOTES RECEIVABLE FROM STOCKHOLDERS
 
During 2000, the Company provided all its officers the opportunity to exercise
their options to purchase common stock, both vested and unvested, by entering
into a full-recourse note receivable with Omnicell. As a result, 1,067,663
options were exercised under note receivable arrangements totaling
$4.6 million. These notes bear interest at either 6.2% or 6.71%, compounded
annually, with payment of both principal and interest due in 3 years.
 
Stock options that were exercised prior to vesting have been shown as shares
subject to repurchase and total 549,742 shares.
 
COMMON STOCK
 
At December 31, 2000, 562,696 shares of common stock are subject to repurchase
by the Company at the original issuance price. These repurchase rights generally
expire ratably over periods of three to five years.
 
STOCK OPTION PLANS
 
The Company has reserved 10,410,000 shares of common stock for issuance under
its 1992 Incentive Stock Plan, 1995 Management Option Plan, and 1999 Equity
Incentive Plan (the Plans). Under the Plans, incentive and nonqualified stock
options or rights to purchase common stock may be granted to employees,
directors, and consultants. Incentive options, nonqualified options, and stock
purchase rights must be priced to be at least 100%, 85% and 85%, respectively,
of the common stock's fair value at the date of grant as determined by the Board
of Directors. Options shall become exercisable as determined by the Board of
Directors. Sales of stock under stock purchase rights are made pursuant to
restricted stock purchase agreements.

(Incentive Plan) for granting of incentive and nonqualified stock options and
rights to purchase common stock to

Company recorded deferred compensation of $62,000 for the difference between the
deemed fair value for accounting purposes and the option price. At December 31,
2000, the deferred compensation has been fully amortized.
 
The Company has recorded deferred stock compensation with respect to options
granted to employees of approximately $2.6 million in the year ended
December 31, 2000 and $136,000 in the three months ended March 31, 2001,
representing the difference between the exercise price of the options and the
deemed fair value of the common stock. These amounts are being amortized to
operations over the vesting periods of the options using the graded vesting
method. Such amortization expense amounted to approximately $816,000 for the
year ended December 31, 2000 and approximately $428,000 for the three months
ended in March 31, 2001. The Company's policy is to use the graded vesting
method for recognizing compensation cost for fixed awards with pro rata vesting.
The Company amortizes the deferred stock-based compensation on the graded
vesting method over the two to four year vesting periods of the applicable stock
options. The graded vesting method provides for vesting of portions of the
overall awards at interim dates and results in greater vesting in earlier years
than the straight line method.
 
For the year ended December 31, 2000, the Company issued options to independent
contractors to purchase 24,063 shares of common stock. The value of the options,
using the Black-Scholes option pricing model, was not significant and the
options were fully vested at issuance.
 
For the year ended December 31, 2000, the Company recorded compensation expense
of approximately $728,000 in connection with granting certain former employees
extended periods (beyond the period specified by the Plans) to exercise their
stock options upon termination of employment.
 
SFAS 123 requires the disclosure of pro forma net income (loss) had the Company
adopted the fair value method as of the beginning of 1995. Under SFAS 123, the
fair value of stock-based awards to employees is calculated through the use of
option pricing models, even though such models were developed to estimate the
fair value of freely tradable, fully transferable options without vesting
restrictions, which significantly differ from the Company's stock option awards.
These models also require subjective assumptions, including future stock price
volatility and expected time to exercise, which greatly affects the calculated
values. The Company's calculations were made using the Black-Scholes option
pricing model with risk-free interest rates of approximately 5.42%, 5.38% and
6.30% in 1998, 1999 and 2000, respectively, and no dividends during the expected
term. Volatility assumed was 0 in 1998 and 1999 and 1.7028 in 2000. The
Company's calculations are based on a multiple-option valuation approach, and
forfeitures are recognized as they occur.

NOTE 16.  INCOME TAXES (CONTINUED)
The Company has established a valuation allowance equal to the net deferred tax
assets due to the uncertainties regarding the realization of deferred tax assets
based on the Company's lack of earnings history.
 
As of December 31, 2000, the Company had a federal net operating loss
carryforward of approximately $38.0 million. The federal net operating loss
carryforward will expire beginning in 2009. The Company also had federal and
state research and development tax credit carryforwards of approximately
$1.4 million and $417,000, respectively. The federal research and development
tax credit carryforwards will expire at various dates beginning in year 2007
through 2020, if not utilized. The state research and development tax credit
carryforward does not expire.
 
Utilization of the net operating losses and tax credits may be subject to a
substantial annual limitation due to the ownership change limitations provided
by the Internal Revenue Code of 1986 and similar state provisions. The annual
limitation may result in the expiration of net operating losses and tax credits
before utilization.
 
NOTE 17.  RELATED PARTY TRANSACTIONS
 
The Company recorded revenues of approximately $9.9 million, $5.1 million and
$1.9 million in 1998, 1999 and 2000, respectively, from the Series J redeemable
convertible preferred stockholder, who was a member of the Company's Board of
Directors until August 11, 1999 (of which approximately $302,000 and $263,000 is
included in accounts receivable at December 31, 1999 and 2000, respectively).
Payment terms are net 45 days.
 
NOTE 18.  RESTATEMENT
 

The Company has restated its financial statements for the years ended
December 31, 1998, 1999 and 2000 and the three months ended March 31, 2001. The
net effect of all adjustments to these years was to increase net income by
$7,000 (or $0.00 per diluted share) for the year ended December 31, 1998 and
decrease net loss by $6.9 million (or $4.66 per diluted share) and $2.6 million
(or $1.53 per diluted share) for the years ended December 31, 1999 and 2000,
respectively. For the three months ended March 31, 2001, the net effect of the
adjustment was to increase the net loss by $67,000 (or $0.02 per diluted share).

  (INFORMATION AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 2000 AND 2001 IS
                                   UNAUDITED)
 
NOTE 18.  RESTATEMENT (CONTINUED)

The adjustment to gross profit in the years ended December 31, 1998, 1999 and
2000 occurred in conjunction with the Company's effort to enhance the accuracy
of its reporting systems and financial data as they relate to revenue
recognition under SOP 97-2 and deferred gross profit on its sales of pharmacy
and supply systems. This effort identified amounts that were included in
deferred gross profit but should have been recognized as revenue as the related
systems were installed. The adjustment to gross profit in the three months ended
March 31, 2000 reflects the write down of certain refurbished inventory
components to the lower of cost or market.

 
The change in estimated purchase price allocation occurred in connection with
the Company's acquisition of the Sure-Med product line. At the time of
acquisition, estimates of the assets and liabilities acquired were made.
Subsequent to that time, it was determined that the actual values of certain
items had differing values than originally estimated. As a result of these
changes, net loss was decreased in 1999 by $1.6 million.
 
The reversal of inventory writedown was recorded in conjunction with an
agreement with a customer to provide free units. The carrying value of the
related inventory was originally written down to its fair value, or zero.
However, upon further review, it was determined that the supporting agreement
did not represent a binding commitment to provide the free units and the
inventory could be sold if not used to fulfill the obligation under the
agreement. Therefore, the resulting inventory writedown was reversed resulting
in a decrease to net loss in 1999 of $1.6 million.
 
NOTE 19.  SUBSEQUENT EVENTS
 
On March 9, 2001, the Company's Board of Directors took the following actions:
 
    - authorized the filing of a registration statement with the Securities and
      Exchange Commission to register shares of its common stock in connection
      with the proposed initial public offering;
 
    - authorized the change of the Company's state of incorporation to Delaware.
 
    - approved an amendment to decrease the number of shares reserved for
      issuance under the Company's 1992 Equity Incentive Plan and 1995
      Management Stock Option Plan by 626,186 shares and to increase the number
      of shares reserved for issuance under the 1999 Equity Incentive Plan by
      626,186 shares.
 
STOCK OPTION GRANTS
 
Subsequent to December 31, 2000, the Company approved grants to employees for
options to purchase 106,281 shares of its common stock at $5.60 per share in
February 2001, 62,813 shares of its common stock at $6.40 per share in March
2001 and 25,813 shares of its common stock at $7.20 per share in May 2001.
 
STOCK SPLIT
 
On April 16, 2001, the Company's stockholders approved a 1-for-1.6 reverse stock
split on the Company's common stock. Accordingly, all common stock share and
per-share data for all periods presented have been restated to reflect this
event.

Board of Directors and Stockholders of
Baxter International Inc.
 
In our opinion, the accompanying balance sheet and the related statements of
operations and of cash flows present fairly, in all material respects, the
financial position of the Sure-Med Division of Baxter Healthcare Corporation
(the Business), an indirect division of Baxter International Inc., at
December 31, 1998, and the results of its operations and its cash flows for the
year then ended in conformity with accounting principles generally accepted in
the United States of America. These financial statements are the responsibility
of the Business' management; our responsibility is to express an opinion on
these financial statements based on our audit. We conducted our audit of these
statements in accordance with auditing standards generally accepted in the
United States of America, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.
 
As discussed in Note 2, the financial statements as of and for the year ended
December 31, 1998 have been restated to correct an error in accounting for
revenue recognition and omission of impairment losses.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  NATURE OF ENTITY AND BASIS OF PRESENTATION
 
The Sure-Med Division of Baxter Healthcare Corporation (the Business) is a
division of Baxter Healthcare Corporation (Baxter), which is in turn a
subsidiary of Baxter International Inc. (BII or Parent). The Business is
principally engaged in the development, manufacturing, marketing and
distribution of an automated distribution system designed to control the
dispensing of narcotics, medications and supplies in both hospital and alternate
site settings. The Business operates mainly in the domestic market, but does
sell some of its products through related parties into certain international
markets, principally Canada and Western Europe. Historically, the Business had
no separate legal status. The accompanying financial statements have been
prepared from the historical accounting records as if the Business had operated
as a separate entity.
 
The financial statements include all of the direct operating expenses of the
Business and allocations of certain shared costs from Baxter and BII.
Allocations are based on actual usage or other methods that approximate actual
usage. Management believes that the allocation methods are reasonable. However,
these allocations are not necessarily indicative of the costs and expenses that
would have resulted if the Business had been operated as a separate entity. The
financial statements also include the push down of the Parent's loss on disposal
of the business (Notes 2 and 12).
 
2.  RESTATEMENT OF FINANCIAL RESULTS
 
In the course of reviewing certain customer contracts and related documents, the
Business determined that it had made promises to customers to deliver specified
software upgrades at future dates. In several cases, the software promise was
determined to be a critical part of the arrangement with the customer. The
existence of these software upgrade promises and their significance to the
customer arrangements caused the Business to conclude that the software
component of its product was more than incidental. Accordingly, the Business has
determined that its revenues should be accounted for in accordance with the
American Institute of Certified Public Accountant's Statement of Position 97-2
("SOP 97-2"), "Software Revenue Recognition." The effects of applying SOP 97-2
on the financial statements were to defer revenues previously recorded
associated with customer arrangements that included promises to deliver software
and those when an installation effort remained as of the balance sheet date. The
Business has restated its financial statements as of December 31, 1998 and
deferred $8.8 million of revenues previously recognized in 1998. Additionally,
the Business needed to adjust opening Investment by Parent for the effects of
applying SOP 97-2 to prior periods. The effect on Investment by Parent at
December 31, 1997 was a loss of approximately $2.8 million, which relates
entirely to the application of SOP 97-2 to the year ended December 31, 1997.
 
In addition, the Parent determined that an impairment of capitalized software
and certain other long-lived assets that arose as a result of the decision to
sell the business should be reflected in these financial statements. Therefore,
an impairment charge of $9.765 million has been reflected in the restated
results of operations of the Business for the year ended December 31, 1998.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
FINANCIAL STATEMENT PRESENTATION
 
The preparation of the financial statements in conformity with generally
accepted accounting principles (GAAP) requires management to make estimates and
assumptions that affect reported amounts and related disclosures. Actual results
could differ from those estimates.
 
REVENUE RECOGNITION
 
Revenues are derived from the sales of automated distribution systems and
subsequent maintenance agreements. The Business markets its systems for sale or
for lease. Automated distribution system sales, which are accounted for in
accordance with SOP 97-2, are recognized when the system has been shipped, all
installation and training services have been provided, no additional performance
obligations exist and collection of the resulting receivables are probable. The
Business does not provide post-contract customer support. All leasing
arrangements are sales-type leases and revenue is recognized when all of the
above conditions are met and the non-cancelable lease term has commenced.
Revenues from service agreements are recognized ratably over the related
contract period.
 
Upon title transfer to the customer, the cost of inventory is reclassified to
deferred costs associated with installations in process. Upon completion of
installation and training services and performance of any other obligations, the
associated deferred costs are relieved to cost of sales to be matched against
the related sales revenue.
 
CASH
 
The Business has not maintained any cash accounts and all cash management
activities have been performed by Baxter and BII.
 
ACCOUNTS RECEIVABLE
 
Accounts receivable are shown net of allowance for doubtful accounts of $278.

</Table>

 
Fixed assets are carried at cost less accumulated depreciation and other
writedowns (Note 2). Expenditures for repairs and maintenance are charged to
expense as incurred and were not significant for 1998. Interest costs applicable
to the construction of major projects are capitalized when material.
 
Depreciation is principally calculated on the straight-line method over the
estimated useful lives of the related assets, which range from three to five
years. Straight-line and accelerated methods of depreciation are used for income
tax purposes.
 
Depreciation expense was $511 in 1998. Capitalized interest was not material in
1998.
 
LEASE ACCOUNTING
 
The Business offers lease financing to its customers under the terms of its
standard five-year sales-type lease. Leases originated by the business result in
the recognition of revenue (present value of lease payments, net of executory
costs) and cost of sales (actual cost of automated distribution system), as well
as the recording of unearned income (excess of gross receivable plus estimated
residual value over the cost of the equipment). Consistent with the Business'
revenue recognition policy and concurrent with lease initiation, all leases are
automatically included in a pool of leases sold on a non-recourse basis to a
third party financial institution under the terms of a rolling lease sale
agreement administered by the Parent ("Lease Sale Program"). As a result of this
arrangement, all leased receivable balances and associated unearned income
amounts are reclassified from their original balance sheet classifications and
reflected as net activity within Investment by Parent (Note 11). The Business

WARRANTIES
 
Estimated future warranty obligations related to products sold or leased are

SEGMENT INFORMATION
 
BII adopted Statement of Financial Accounting Standards No. 131, "Disclosures
about Segments of an Enterprise and Related Information" (SFAS No. 131) in 1998.
This statement establishes standards for the reporting of information about
operating segments in annual and interim financial statements. Operating
segments are defined as components of an enterprise for which separate financial
information is available that is evaluated regularly by the chief operating
decision maker(s) in deciding how to allocate resources and in assessing
performance. SFAS No. 131 also requires disclosures about products and services,
geographic areas and major customers. The adoption of SFAS No. 131 did not
affect results of operations, financial position or the disclosure of segment
information. Refer to Note 10 for the Business' segment information.
 
4.  TRANSACTIONS WITH RELATED PARTIES
 
A portion of the operations of the Business involves transactions with
subsidiaries and divisions of BII.
 
A division of Baxter provides accounting, administrative and other services
related to the business' sales-type leases with its customers. The Business is
charged for such services at a rate which management believes approximates the
market rate. As discussed in Note 3, Baxter sells substantially all of the
Business' lease receivables to an independent third party.
 
In addition, the corporate headquarters of BII and the divisional headquarters
of Baxter provide to the Business certain other accounting, tax, and
administrative services. All significant expenses relating to such services are
included in the financial statements of the Business.
 
The financial statements of the Business include expenses of $4,288 in 1998 for
services provided by related parties.
 
5.  FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
 
CONCENTRATIONS OF CREDIT RISK
 
In the normal course of business, the company provides credit to customers in
the health-care industry, performs credit evaluations of these customers and
maintains reserves for potential credit losses which, when realized, have been
within the range of management's allowance for doubtful accounts.
 
The carrying values of financial instruments approximate their fair values.

7.  STOCK-BASED COMPENSATION PLANS
 
Certain employees of the Business participate in stock-based compensation plans
sponsored by BII. Such plans principally include fixed stock option plans and an
employee stock purchase plan. BII applies APB Opinion No. 25, "Accounting for
Stock Issued to Employees," and related interpretations in accounting for its
plans. Accordingly, no compensation cost has been recognized by BII for its
fixed stock option plans and its stock purchase plan. These plans are the sole
responsibility of BII and, accordingly, no information is presented herein.
 
8.  RETIREMENT AND OTHER BENEFIT PROGRAMS
 
Substantially all of the employees of the Business are eligible to participate
in BII's contributory defined contribution plan, non-contributory defined
benefit pension plans and certain other postretirement benefit plans. These
plans are the sole responsibility of BII and, accordingly, no information is
presented herein related to those plans. Total expense recognized by the
Business relating to these plans was $329 in 1998.
 
9.  INCOME TAXES
 
The results of the Business' operations are included in the consolidated tax
return of BII. These financial statements do not reflect income tax benefit for
1998 or recent prior years in which losses were incurred. As instructed by its
parent, the Business calculates its taxes as if it were filing its own return.
On a separate return basis, the losses incurred in recent years through
December 31, 1998 would have given rise to net operating loss carryforwards and
related deferred tax assets. Due to the uncertainty of ultimate utilization of
those carryforwards on a separate-return basis, the Business would have recorded
valuation allowances for the full amounts of those deferred tax assets. The tax
effects of other temporary differences that give rise to deferred tax assets and
liabilities at December 31, 1998 were not material.
 
The Business, on a stand-alone basis, would have a net operating loss
carryforward for federal income tax purposes of approximately $48,000 at
December 31, 1998. However, since the Business has been included in the
consolidated tax filings of BII, its prior losses have been utilized in the BII

the future, no net operating losses would be available.

activities and products of which are described in Note 1.

11.  INVESTMENT BY PARENT
 
Investment by Parent represents Baxter's ownership interest in the recorded net
assets of the Business. All cash transactions with Baxter and BII are reflected
in this amount. In addition, all intercompany expenses charged from the Parent
are not expected to be settled and, therefore, while recorded as expenses in the
appropriate period, have been considered additional contributions from the
Parent. The Business has not been charged interest on any investments made by
the Parent other than those amounts capitalized into fixed assets as disclosed
in Note 2. A summary of the activity is as follows:

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
    Section 145 of the Delaware General Corporation Law (the DGCL) authorizes a
court to award, or a corporation's board of directors to grant indemnity to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities, including
reimbursement for expenses incurred, arising under the Securities Act.
 
    As permitted by the DGCL, our Certificate of Incorporation, which will
become effective prior to the closing of this offering, includes a provision
that eliminates the personal liability of our directors for monetary damages for
breach of fiduciary duty as a director, except for liability (1) for any breach
of the director's duty of loyalty to us or our stockholders; (2) for acts or
omissions not in good faith or that involve intentional misconduct or knowing
violation of law; (3) under Section 174 of the DGCL regarding unlawful dividends
and stock purchases; or (4) for any transaction from which the director derived
an improper personal benefit.
 
    As permitted by the DGCL, our Certificate of Incorporation and/or our
Bylaws, which will become effective prior to the closing of this offering,
provide that (1) we are required to indemnify our directors and officers to the
fullest extent permitted by the DGCL, subject to certain very limited
exceptions; (2) we are permitted to indemnify our other employees to the extent
that we indemnify our officers and directors, unless otherwise required by law,
our Certificate of Incorporation, our Bylaws or agreements; (3) we are required
to advance expenses, as incurred, to our directors and officers in connection
with a legal proceeding to the fullest extent permitted by the DGCL, subject to
certain very limited exceptions; and (4) the rights conferred in our Bylaws are
not exclusive.
 
    Prior to the closing of this offering, we intend to enter into indemnity
agreements with each of our current directors and officers to give such
directors and officers additional contractual assurances regarding the scope of
the indemnification set forth in our Certificate of Incorporation and our Bylaws
and to provide additional procedural protections. At present, there is no
pending litigation or proceeding involving a director, officer or employee of
Omnicell.com regarding which indemnification is sought, nor are we aware or any
threatened litigation that may result in claims for indemnification.
 
    With approval by the board of directors, we expect to obtain directors' and
officers' liability insurance. Reference is made to the underwriting agreement
contained in Exhibit 1.1 hereto, which contains provisions indemnifying our
officers and directors against certain liabilities.

    All other schedules for which provision is made in the applicable accounting

ITEM 17.  UNDERTAKINGS.
 
    The Registrant hereby undertakes to provide the Underwriters at the closing
specified in the Underwriting Agreement, certificates in such denominations and
registered in such names as required by the Underwriters to permit prompt
delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 14 or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit, or proceeding) is asserted by
such director, officer, or controlling person in connection with the securities
being registered hereunder, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
    The Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act, the
       information omitted from the form of Prospectus filed as part of this
       Registration Statement in reliance upon Rule 430A and contained in a form
       of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
       (4) or 497(h) under the Securities Act shall be deemed to be a part of
       this Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act,
       each post-effective amendment that contains a form of Prospectus shall be
       deemed to be a new Registration Statement relating to the securities
       offered therein, and the offering of such securities at that time shall
       be deemed to be the initial bona fide offering thereof.

U.S. BANCORP PIPER JAFFRAY INC.
CIBC WORLD MARKETS CORP.
SG COWEN SECURITIES CORPORATION
     As Representatives of the several
Underwriters named in Schedule I hereto

c/o U.S. Bancorp Piper Jaffray Inc.
U.S. Bancorp Center
800 Nicollet Mall
Minneapolis, Minnesota  55402

Ladies and Gentlemen:

     Omnicell, Inc., a Delaware corporation (the "Company"), proposes to issue
and sell to the several Underwriters named in Schedule I hereto (the
"Underwriters") an aggregate of 6,000,000 shares (the "Firm Shares") of common
stock, $0.001 par value per share (the "Common Stock"), of the Company. The
Company has also granted to the several Underwriters an option to purchase up to
900,000 additional shares of Common Stock on the terms and for the purposes set
forth in Section 3 hereof (the "Option Shares"). The Firm Shares and any Option
Shares purchased pursuant to this Purchase Agreement are herein collectively
called the "Securities."

     The Company hereby acknowledges that in connection with the proposed
offering of the Securities, it has requested U.S. Bancorp Piper Jaffray Inc. to
administer a directed share program (the "Directed Share Program") under which

up to 300,000 Firm Shares, or five percent (5%) of the Firm Shares, to be
purchased by you (the "Reserved Shares") shall be reserved for sale by you at
the initial public offering price to the Company's officers, directors,
employees, and consultants and others having a relationship with the Company
(the "Directed Share Participants") as part of the distribution of the
Securities by the Underwriters, subject to the terms of this Agreement, the
applicable rules, regulations and interpretations of the National Association of
Securities Dealers, Inc. ("NASD") and all other applicable laws, rules and

----------
(1) Plus an option to purchase up to 900,000 additional shares to cover
over-allotments.


                                       1

regulations (the "Directed Share Program"). The number of Securities available
for sale to the general public will be reduced to the extent that Directed Share
Participants purchase Reserved Shares. You may offer any Reserved Shares not
purchased by Directed Share Participants to the general public on the same basis
as the other Securities being issued and sold hereunder. The Company has
supplied U.S. Bancorp Piper Jaffray Inc. with the names, addresses and telephone
numbers of the individuals or other entities which the Company has designated to
be participants in the Directed Share Program. It is understood that any number
of those designated to participate in the Directed Share Program may decline to
do so.

     The Company hereby confirms its agreement with respect to the sale of the
Securities to the several Underwriters, for whom you are acting as
Representatives (the "Representatives").

     1. REGISTRATION STATEMENT AND PROSPECTUS. A registration statement on Form
S-1 (File No. 333-57024) with respect to the Securities, including a preliminary
form of prospectus, has been prepared by the Company in conformity with the
requirements of the Securities Act of 1933, as amended (the "Act"), and the
rules and regulations ("Rules and Regulations") of the Securities and Exchange
Commission (the "Commission") thereunder, and has been filed with the
Commission; one or more amendments to such registration statement have also been
so prepared and have been, or will be, so filed; and, if the Company has elected
to rely upon Rule 462(b) of the Rules and Regulations to increase the size of
the offering registered under the Act, then the Company will prepare and file
with the Commission a registration statement with respect to such increase
pursuant to Rule 462(b) of the Rules and Regulation. Copies of such registration
statement(s) and amendments, and each related preliminary prospectus have been
delivered to you.

     If the Company has elected not to rely upon Rule 430A of the Rules and
Regulations, the Company has prepared and will promptly file an amendment to the
registration statement and an amended prospectus that satisfy the requirements
of the Act and the Rules and Regulations. If the Company has elected to rely
upon Rule 430A of the Rules and Regulations, then it will prepare and file a
prospectus (or a term sheet meeting the requirements of Rule 434 of the Rules
and Regulations) pursuant to Rule 424(b) of the Rules and Regulations that
discloses the information previously omitted from the prospectus in reliance
upon Rule 430A of the Rules and Regulations. Such registration statement, as
amended at the time it is or was declared effective by the Commission, and, in
the event of any amendment thereto after the effective date and prior to the
First Closing Date (as hereinafter defined), such registration statement as so
amended (but only from and after the effectiveness of such amendment), including
a registration statement (if any) filed pursuant to Rule 462(b) of the Rules and
Regulations increasing the size of the offering registered under the Act, and
information (if any) deemed to be part of the registration statement at the time
of effectiveness pursuant to Rules 430A(b) and 434(d) of the Rules and
Regulations, is hereinafter called the "Registration Statement." The prospectus
included in the Registration Statement at the time it is or was declared
effective by the Commission is hereinafter called the "Prospectus," except that
if any prospectus (including any term sheet meeting the requirements of Rule 434
of the Rules and Regulations provided by the Company for use with a prospectus
subject to completion within the meaning of Rule 434 of the Rules and
Regulations in order to meet the requirements of Section 10(a) of the Act) filed
by the Company with the Commission pursuant to Rule 424(b) (and Rule 434, if
applicable) of the Rules and Regulations, or any other such prospectus provided
to the Underwriters by the Company for use 



                                       2
<Page>

in connection with the offering of the Securities (whether or not required to be
filed by the Company with the Commission pursuant to Rule 424(b) of the Rules
and Regulations) differs from the prospectus on file at the time the
Registration Statement is or was declared effective by the Commission, then the
term "Prospectus" shall refer to such differing prospectus (including any term
sheet within the meaning of Rule 434 of the Rules and Regulations) from and
after the time such prospectus is filed with the Commission or transmitted to
the Commission for filing pursuant to such Rule 424(b) (and Rule 434, if
applicable) of the Rules and Regulations or from and after the time it is first
provided to the Underwriters by the Company for such use. The term "Preliminary
Prospectus" as used herein means any preliminary prospectus included in the
Registration Statement prior to the time it becomes or became effective under
the Act, and any prospectus subject to completion as described in Rule 430A or
Rule 434 of the Rules and Regulations.

     2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         (a) The Company represents and warrants to, and agrees with, the
several Underwriters as follows:

              (i) No order preventing or suspending the use of any Preliminary
     Prospectus has been issued by the Commission, nor has any proceeding for
     that purpose been initiated or, to the Company's knowledge, threatened by
     the Commission, and each Preliminary Prospectus, at the time of filing
     thereof, did not contain an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading; except that the foregoing shall not apply to
     statements in or omissions from any Preliminary Prospectus in reliance
     upon, and in conformity with, written information furnished to the Company
     by you, or by any Underwriter through you, specifically for use in the
     preparation thereof.

              (ii) As of the time the Registration Statement (or any
     post-effective amendment thereto, including a registration statement (if
     any) filed pursuant to Rule 462(b) of the Rules and Regulations increasing
     the size of the offering registered under the Act) is or was declared
     effective by the Commission, upon the filing or first delivery to the
     Underwriters of the Prospectus (or any supplement to the Prospectus
     (including any term sheet meeting the requirements of Rule 434 of the Rules
     and Regulations)) and at the First Closing Date and Second Closing Date (as
     hereinafter defined), (A) the Registration Statement and Prospectus (in
     each case, as so amended and/or supplemented) conformed or will conform in
     all material respects to the requirements of the Act and the Rules and
     Regulations, (B) the Registration Statement (as so amended) did not or will
     not include an untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading and (C) the Prospectus (as so
     supplemented) did not or will not include an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein, in light of the circumstances in
     which they are or were made, not misleading; except that the foregoing
     shall not apply to statements in or omissions from any such document in
     reliance upon, and in conformity with, written information furnished to the
     Company by you, or by any 



                                       3
<Page>

     Underwriter through you, specifically for use in the preparation thereof.
     If the Registration Statement has been declared effective by the
     Commission, no stop order suspending the effectiveness of the Registration
     Statement has been issued, and no proceeding for that purpose has been
     initiated or, to the Company's knowledge, threatened by the Commission.

              (iii) The Company has been duly organized and is validly existing
     as a corporation in good standing under the laws of its jurisdiction of
     incorporation. The Company has full corporate power and authority to own,
     lease and operate its properties and conduct its business as currently
     carried on and as proposed or described in the Registration Statement and
     Prospectus and is duly qualified to do business as a foreign corporation in
     good standing in each jurisdiction in which it owns or leases real property
     or in which the conduct of its business makes such qualification necessary
     and in which the failure to so qualify would have a material adverse effect
     upon its business as currently carried on and as proposed or described in
     the Registration Statement and Prospectus, properties, condition (financial
     or otherwise), net worth or results of operations taken as a whole (a
     "Material Adverse Effect"). Each of the subsidiaries of the Company as
     listed in Exhibit 21.1 to Item 16(a) of the Registration Statement, as
     listed in Exhibit A hereto (collectively, the "Subsidiaries"), has been
     duly organized and is validly existing as a corporation in good standing
     under the laws of its jurisdiction of incorporation, with corporate power
     and authority to own, lease and operate its properties and conduct its
     business as currently carried on and as proposed or described in the
     Registration Statement and Prospectus and is duly qualified to do business
     as a foreign corporation in good standing in each jurisdiction in which it
     owns or leases real property or in which the conduct of its business makes
     such qualification necessary and in which the failure to so qualify would
     have a Material Adverse Effect. The Subsidiaries are the only subsidiaries
     (as defined in the Act), direct or indirect, of the Company. The
     outstanding shares of capital stock of each of the Subsidiaries have been
     duly authorized and validly issued, are fully paid and non-assessable and
     to the extent shown in Exhibit A hereto are owned by the Company or another
     Subsidiary free and clear of all liens, encumbrances and equities and
     claims; and no options, warrants or other rights to purchase, agreements or
     other obligations to issue or other rights to convert any obligations into
     shares of capital stock or ownership interests in any of the Subsidiaries
     are outstanding.

              (iv) The consolidated financial statements of the Company and the
     Subsidiaries, together with the notes thereto, set forth in the
     Registration Statement and Prospectus comply in all material respects with
     the requirements of the Act and fairly present the consolidated financial
     condition of the Company and the Subsidiaries as of the dates indicated and
     the results of operations and changes in cash flows for the periods therein
     specified in conformity with generally accepted accounting principles
     consistently applied throughout the periods involved (except as otherwise
     specifically stated therein); the pro forma financial data included in the
     Registration Statement and Prospectus comply as to form in all material
     respects with the applicable accounting requirements of Regulation S-X of
     the Securities Act, and the pro forma adjustments have been properly
     applied to the historical amounts in the compilation of those statements;
     and the other financial and statistical data and supporting schedules
     included in the Registration Statement and Prospectus present fairly and
     accurately the information required to be 



                                       4
<Page>

     stated therein and have been prepared on a basis consistent with such
     financial statements and the books and records of the Company and the
     Subsidiaries. Other than the consolidated financial statements and
     schedules included in the Registration Statement and Prospectus, no other
     financial statements or schedules are required to be included in the
     Registration Statement or Prospectus. Ernst & Young LLP, which has
     expressed its opinion with respect to the audited consolidated financial
     statements included in the Registration Statement and Prospectus, is an
     independent public accountant as required by the Act and the Rules and
     Regulations.

              (v) Except as set forth in the Prospectus, subsequent to the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, the Company and the Subsidiaries have not
     incurred any material liabilities or obligations, direct or contingent, or
     entered into any material transactions, or declared or paid any dividends
     or made any distribution of any kind with respect to their respective
     capital stock; and there has not been any change in the capital stock
     (other than a change in the number of outstanding shares of Common Stock
     due to the issuance of shares upon the exercise of outstanding options or
     warrants disclosed as outstanding in the Registration Statement and
     Prospectus), or any material change in the short-term or long-term debt, or
     any issuance of options, warrants, convertible securities, or other rights
     to purchase the capital stock (other than in the ordinary course of
     business pursuant to the Company's equity incentive plans disclosed in the
     Registration Statement and Prospectus) of the Company or the Subsidiaries,
     or any material adverse change, or any development involving a prospective
     change, which has had or is reasonably likely to have a Material Adverse
     Effect.

              (vi) Except as set forth in the Prospectus, there is not pending
     or, to the Company's knowledge, threatened or contemplated, any action,
     suit, or proceeding to which the Company, any of the Subsidiaries or any of
     the officers of the Company or any of the Subsidiaries is a party before or
     by any court or governmental agency, authority, or body, or any arbitrator,
     which is reasonably possible to have a Material Adverse Effect.

              (vii) There are no contracts or documents that are required to be
     filed as exhibits to the Registration Statement by the Act or by the Rules
     and Regulations that have not been so filed. The documents incorporated by
     reference in the Prospectus, if any, at the time filed with the Commission
     conformed, in all respects to the requirements of the Securities Exchange
     Act of 1934 (the "Exchange Act") or the Act, as applicable, and the Rules
     and Regulations.

              (viii) This Agreement has been duly authorized, executed and
     delivered by the Company, and constitutes a valid, legal, and binding
     obligation of the Company, enforceable in accordance with its terms, except
     as rights to indemnity hereunder may be limited by federal or state
     securities laws and except as such enforceability may be limited by
     bankruptcy, insolvency, reorganization or similar laws affecting the rights
     of creditors generally, and subject to general principles of equity. The
     execution, delivery, and performance of this Agreement and the consummation
     of the transactions herein contemplated will not result in a breach or
     violation of any of the terms and provisions of, or constitute a default
     under, any statute, any agreement or instrument to which the 



                                       5
<Page>

     Company or any of the Subsidiaries is a party or by which the Company or
     any of the Subsidiaries is bound or to which any of their property is
     subject, the charter or bylaws of the Company or any Subsidiary, or any
     order, rule, regulation, or decree of any court or governmental agency or
     body having jurisdiction over the Company, any of the Subsidiaries or any
     of the properties of the Company or any of the Subsidiaries; no consent,
     approval, authorization, or order of, or filing with, any court or
     governmental agency or body is required for the execution, delivery and
     performance of this Agreement or for the consummation of the transactions
     contemplated hereby, including the issuance or sale of the Securities by
     the Company, except such as may be required under the Act or state
     securities or blue sky laws or in connection with the review of the
     offering by the National Association of Securities Dealers, Inc. ("NASD");
     and the Company has full power and authority to enter into this Agreement
     and to authorize, issue and sell the Securities as contemplated by this
     Agreement.

              (ix) All of the issued and outstanding shares of capital stock of
     the Company, including the outstanding shares of Common Stock, are duly
     authorized and validly issued, fully paid, and nonassessable, have been
     issued in compliance with all federal and state securities laws, were not
     issued in violation of or subject to any preemptive rights or other rights
     to subscribe for or purchase securities, and the holders thereof are not
     subject to personal liability by reason of being such holders; the
     Securities which may be sold hereunder by the Company have been duly
     authorized and, when issued, delivered and paid for in accordance with the
     terms hereof, will have been validly issued and will be fully paid and
     nonassessable, and the holders thereof will not be subject to personal
     liability by reason of being such holders; and the capital stock of the
     Company, including the Common Stock, conforms to the description thereof in
     the Registration Statement and Prospectus. The certificates for the
     Securities are in due and proper form and conform in all material respects
     to the requirements of the Delaware General Corporation Law. Except as
     otherwise described in the Registration Statement and Prospectus, there are
     no preemptive rights or other rights to subscribe for or to purchase, or
     any restriction upon the voting or transfer of, any shares of Common Stock
     pursuant to the Company's charter, bylaws, or any agreement or other
     instrument to which the Company is a party or by which the Company is
     bound. Except as described in the Registration Statement and the
     Prospectus, neither the filing or effectiveness of the Registration
     Statement nor the offering or sale of the Securities as contemplated by
     this Agreement gives rise to any rights for or relating to the registration
     of any shares of Common Stock or other securities of the Company. Except as
     described in the Registration Statement and the Prospectus, there are no
     options, warrants, agreements, contracts or other rights in existence to
     purchase or acquire from the Company any shares of the capital stock of the
     Company. As of the date set forth thereon, the Company has an authorized
     and outstanding capitalization as set forth in the Registration Statement
     and the Prospectus under the heading "Capitalization".

              (x) The Company and the Subsidiaries hold, and are operating in
     compliance in all material respects with, all franchises, grants,
     authorizations, licenses, permits, easements, consents, certificates and
     orders of any governmental or self-regulatory body required for the conduct
     of their businesses as currently conducted and as proposed to be conducted
     as described in the Registration Statement and Prospectus, and 



                                       6
<Page>

     all such franchises, grants, authorizations, licenses, permits, easements,
     consents, certifications and orders are valid and in full force and effect;
     and the Company and the Subsidiaries have not violated and currently are in
     compliance in all material respects with all applicable federal, state,
     local and foreign laws, regulations, orders, ordinances and decrees.

              (xi) The Company and each of the Subsidiaries have good and
     marketable title to all property owned by them and valid rights to use all
     property described in the Registration Statement and Prospectus or
     necessary for the conduct of their respective businesses as described in
     the Registration Statement and Prospectus, in each case free and clear of
     all liens, claims, security interests or other encumbrances, except such as
     are described in the Registration Statement and the Prospectus; the
     property held under lease by the Company and the Subsidiaries is held by
     them under valid, subsisting and enforceable leases with only such
     exceptions with respect to any particular lease as do not interfere in any
     material respect with the conduct of the business of the Company and the
     Subsidiaries.

              (xii) The Company and each of the Subsidiaries owns or possesses
     all patents, patent applications, trademarks, service marks, tradenames,
     trademark registrations, service mark registrations, copyrights, licenses,
     inventions, trade secrets and rights necessary for the conduct of its
     respective business as currently carried on and as proposed, on the date
     hereof, to be carried on as described in the Registration Statement and
     Prospectus (collectively, the "Intellectual Property"). Except as described
     in the Prospectus, (i) no third parties have received rights to any such
     Intellectual Property from the Company, other than licenses granted in the
     ordinary course and those that would not have a Material Adverse Effect;
     (ii) to the Company's knowledge, there is no infringement by third parties
     of any such Intellectual Property; (iii) there is no pending or, to the
     Company's knowledge, threatened action, suit, proceeding or claim by others
     challenging the Company's or any Subsidiary's rights in or to any such
     Intellectual Property, and the Company is unaware of any facts which would
     form a basis for any such claim; (iv) there is no pending or, to the
     Company's knowledge, threatened action, suit, proceeding or claim by others
     challenging the validity or scope of any such Intellectual Property, and
     the Company is unaware of any facts which would form a basis for any such
     claim; (v) there is no pending or, to the Company's knowledge, threatened
     action, suit, proceeding or claim by others that the Company or any of the
     Subsidiaries infringes or otherwise violates, or would infringe or
     otherwise violate upon commercialization of its products and product
     candidates described in the Prospectus, any patent, trademark, copyright,
     trade secret or other proprietary rights of others, and the Company is
     unaware of any facts which would form a basis for any such claim; (vi) to
     the Company's knowledge there is no patent or patent application that
     contains claims that dominate or may dominate any Intellectual Property
     described in the Prospectus as being owned by or licensed to the Company or
     any of the Subsidiaries or that is necessary for the conduct of their
     businesses as currently or contemplated to be conducted or that interferes
     with the issued or pending claims of any such Intellectual Property; and
     (vii) there is no prior art of which the Company is aware that may render
     any patent held by the Company or any of the Subsidiaries invalid or any
     patent application held by the Company or any of the Subsidiaries
     unpatentable which has not been disclosed to the 



                                       7
<Page>

     U.S. Patent and Trademark Office. None of the technology employed by the
     Company has been obtained or, to the Company's knowledge, is being used by
     the Company in violation of the rights of any person or third party. The
     Company knows of no infringement by others of Intellectual Property owned
     by or licensed to the Company. Exhibit B lists all of the issued patents
     owned in whole or in part by the Company or any Subsidiary.

              (xiii) Neither the Company nor any of the Subsidiaries is in
     violation of its respective charter or bylaws or in breach of or otherwise
     in default in the performance of any material obligation, agreement, or
     condition contained in any bond, debenture, note, indenture, loan
     agreement, or any other material contract, lease, or other instrument to
     which it is subject or by which it may be bound, or to which any of the
     material property or assets of the Company or any of the Subsidiaries is
     subject.

              (xiv) The Company and each Subsidiary has filed all federal,
     state, local and foreign income and franchise tax returns and tax forms
     required to be filed and is not in default in the payment of any taxes
     which were payable pursuant to said returns or any assessments with respect
     thereto, other than any which the Company or any Subsidiary is contesting
     in good faith and as to which adequate reserves have been provided. Such
     returns and forms are complete and correct in all material respects. The
     Company and each Subsidiary has made all payroll withholdings required to
     be made by it with respect to employees. The charges, accruals and reserves
     on the books of the Company and each Subsidiary in respect of any tax
     liability for any year not finally determined are adequate to meet any
     assessments or reassessments for additional taxes. There have been no tax
     deficiencies asserted and, to the Company's knowledge, no tax deficiency
     might be reasonably asserted or threatened against the Company or any
     Subsidiary that could individually or in the aggregate have a Material
     Adverse Effect.

              (xv) The Company has not distributed and will not distribute any
     prospectus or other offering material in connection with the offering and
     sale of the Securities other than any Preliminary Prospectus or the

     on Form 8-A or other applicable form under the Exchange Act, became or will
     become effective.

              (xvii) Other than the Subsidiaries and as set forth on Exhibit C,
     the Company does not own, directly or indirectly, any shares of capital

     generally accepted accounting principles and to maintain accountability for
     assets; (C) access to assets is permitted only in accordance with
     management's general and specific authorization; and (D) the recorded

              (xix) Other than as contemplated by this Agreement, the Company
     has not incurred any liability for any finder's or broker's fee, or agent's
     commission in connection with the execution and delivery of this Agreement

              (xx) Except as otherwise disclosed in the Registration Statement
     and Prospectus, the Company and each of the Subsidiaries is insured by
     insurers of recognized financial responsibility against such losses and
     risks and in such amount as are customary in the business in which they are
     engaged. All policies of insurance insuring the Company or any Subsidiary
     or any of their respective businesses, assets, employees, officers and
     directors are in full force and effect, and the Company and the
     Subsidiaries are in compliance with the terms of such policies in all
     material respects. There are no claims by the Company or any of Subsidiary
     under any such policy or instrument as to which any insurance company is
     denying liability or defending under a reservation of rights clause.

              (xxi) Neither the Company nor any Subsidiary has sent or received
     any notice of termination of any of the contracts or agreements referred to
     or described in, or filed as an exhibit to, the Registration Statement, and
     no such termination has been threatened by the Company, any Subsidiary or
     any other party to any such contract or agreement.

              (xxii) All statistical and market-related data included in the
     Prospectus are based on or derived from sources that the Company believes
     to be reliable and accurate, and the Company has obtained the written

              (xxiii) Neither the Company nor, to the Company's knowledge, any
     of its affiliates, has taken or will take, directly or indirectly, any
     action designed to or which has constituted, caused or resulted in, or
     which might reasonably be expected to constitute, cause or result in, under
     the Exchange Act or otherwise, the stabilization or manipulation of the
     price of any security of the Company to facilitate the sale or resale of
     the Securities. The Company has not effected any sales of Common Stock
     which are required to be disclosed in response to Item 701 of Regulation
     S-K under the Act which have not been so disclosed in the Registration
     Statement. The Company acknowledges that the Underwriters may engage in
     passive market making transactions in the Securities on the Nasdaq Stock
     Market in accordance with Regulation M under the Exchange Act.

              (xxiv) Except as set forth in the Prospectus, immediately after
     the issuance and sale of the Securities to the Underwriters, no shares of
     preferred stock of the Company shall be issued and outstanding and no
     holder of any shares of capital stock, 


                                       9
<Page>

     securities convertible into or exchangeable or exercisable for capital
     stock or options, warrants or other rights to purchase capital stock or any
     other securities of the Company shall have any existing or future right to
     acquire any shares of preferred stock of the Company.

              (xxv) Neither the Company nor any Subsidiary is, and after the
     offering and sale of the Securities, will be, an "investment company" or a
     "promoter," "principal underwriter" for an entity "controlled" by an
     "investment company," as such terms are defined in the Investment Company
     Act of 1940, as amended (the "Investment Company Act").

              (xxvi) The Company and the Subsidiaries have operated and
     currently are in compliance in all material respects with applicable United
     States Food and Drug Administration ("FDA") rules, regulations and
     policies, if any.

              (xxvii) The Company and each Subsidiary is in compliance in all
     material respects with all presently applicable provisions of the Employee
     Retirement Income Security Act of 1974, as amended, including the
     regulations and published interpretations thereunder ("ERISA"); no
     "reportable event" (as defined in ERISA) has occurred with respect to any
     "pension plan" (as defined in ERISA) for which the Company or any
     Subsidiary would have any liability; neither the Company nor any Subsidiary
     has incurred or expects to incur liability under (A) Title IV of ERISA with
     respect to termination of, or withdrawal from, any "pension plan" or (B)
     Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended,
     including the regulations and published interpretations thereunder (the
     "Code"); and each "pension plan" for which the Company or any Subsidiary
     would have any liability that is intended to be qualified under Section
     401(a) of the Code is so qualified in all material respects and nothing has
     occurred, whether by action or by failure to act, which would cause the
     loss of such qualification.

              (xxviii) To the Company's knowledge, there are no affiliations or
     associations between any member of the NASD and any of the Company's
     officers, directors or 5% or greater securityholders, except as set forth
     in the Registration Statement.

              (xxix) Except as disclosed in the Prospectus, neither the Company
     nor any Subsidiary is in violation of any statute, any rule, regulation,
     decision or order of any governmental agency or body or any court, domestic
     or foreign, relating to the use, disposal or release of hazardous or toxic
     substances or relating to the protection or restoration of the environment
     or human exposure to hazardous or toxic substances (collectively,
     "Environmental Laws"), owns or operates any real property contaminated with
     any substance that is subject to any Environmental Laws, is liable for any
     off-site disposal or contamination pursuant to any environmental laws, or
     is subject to any claim relating to any environmental laws, which
     violation, contamination, liability or claim would individually or in the
     aggregate have a Material Adverse Effect; and the Company is not aware of
     any pending investigation which might lead to such a claim.

              (xxx) The Company's migratory merger from California to Delaware
     (the "Reincorporation") is effective. The Reincorporation complied in all
     respects with California, Delaware and federal securities laws and there
     are no material liabilities of the Company's predecessor California entity
     that have not been discharged or otherwise accounted for in connection with
     such merger.

              (xxxi) No consent, approval, authorization or order of, or
     qualification with, any governmental body or agency, other than those
     obtained, is required in connection with the offering of the Reserved
     Shares in any jurisdiction where the Reserved Shares are being offered.

              (xxxii) The Company has not offered, or caused any Underwriter or
     its affiliates to offer, Securities to any person pursuant to the Directed
     Share Program with the specific intent to unlawfully influence (A) a
     customer or supplier of the Company to alter the customer's or supplier's
     level or type of business with the Company, or (B) a trade journalist or
     publication to write or publish favorable information about the Company or
     its products.

         (b) Any certificate signed by any officer of the Company and delivered
to you or to counsel for the Underwriters shall be deemed to be a representation
and warranty by the Company to each Underwriter as to the matters covered
thereby.

     3.  PURCHASE, SALE AND DELIVERY OF SECURITIES.

         (a) On the basis of the representations, warranties and agreements
herein contained, but subject to the terms and conditions herein set forth, the
Company agrees to issue and sell 6,000,000 Firm Shares to the several
Underwriters, and each Underwriter agrees, severally and not jointly, to
purchase from the Company the number of Firm Shares set forth opposite the name
of such Underwriter in Schedule I hereto. The purchase price for each Firm Share
shall be $____ per share. In making this Agreement, each Underwriter is
contracting severally and not jointly; except as provided in Section 8 hereof,
the agreement of each Underwriter is to purchase only the number of Firm Shares
specified as to such Underwriter in Schedule I.

     The Firm Shares will be delivered by the Company to you for the accounts of
the several Underwriters against payment of the purchase price therefor by
Federal Funds wire transfer payable to the order of the Company at the offices
of U.S. Bancorp Piper Jaffray Inc., U.S. Bancorp Center, 800 Nicollet Mall,
Minneapolis, Minnesota, or such other location as may be mutually acceptable, at
9:00 a.m. Central time on the third (or if the Securities are priced, as
contemplated by Rule 15c6-1(c) under the Exchange Act, after 4:30 p.m. Eastern
time, the fourth) full business day following the date hereof, or at such other
time and date as you and the Company determine pursuant to Rule 15c6-1(a) under
the Exchange Act, such time and date of delivery being herein referred to as the
"First Closing Date." If the Representatives so elect, delivery of the Firm
Shares may be made by credit through full fast transfer to the accounts at the
Depository Trust Company ("DTC") designated by the Representatives. Certificates
representing the Firm Shares, in definitive form and in such denominations and
registered in such names as you may request upon at least two (2) business days'
prior notice to the Company, 



                                       11
<Page>

will be made available for checking and packaging not later than 10:30 a.m.,
Central time, on the business day next preceding the First Closing Date at the
offices of U.S. Bancorp Piper Jaffray Inc., U.S. Bancorp Center, 800 Nicollet
Mall, Minneapolis, Minnesota, or such other location as may be mutually
acceptable.

         (b) On the basis of the representations, warranties and agreements
herein contained, but subject to the terms and conditions herein set forth, the
Company hereby grants to the several Underwriters an option to purchase all or
any portion of the Option Shares at the same purchase price as the Firm Shares,
for use solely in covering any over-allotments made by the Underwriters in the
sale and distribution of the Firm Shares. The option granted hereunder may be
exercised at any time (but not more than once) within thirty (30) days after the
effective date of this Agreement upon notice (confirmed in writing) by the
Representatives to the Company setting forth the aggregate number of Option
Shares as to which the several Underwriters are exercising the option, the names
and denominations in which the certificates for the Option Shares are to be
registered and the date and time, as determined by you, when the Option Shares
are to be delivered, such time and date being herein referred to as the "Second
Closing" and "Second Closing Date," respectively; provided, however, that the
Second Closing Date shall not be earlier than the First Closing Date nor earlier
than the second business day after the date on which the option shall have been
exercised. The number of Option Shares to be purchased by each Underwriter shall
be the same percentage of the total number of Option Shares to be purchased by
the several Underwriters as the number of Firm Shares to be purchased by such
Underwriter is of the total number of Firm Shares to be purchased by the several
Underwriters, as adjusted by the Representatives in such manner as the
Representatives deem advisable to avoid fractional shares. No Option Shares
shall be sold and delivered unless the Firm Shares previously have been, or
simultaneously are, sold and delivered.

     The Option Shares will be delivered by the Company to you for the accounts
of the several Underwriters against payment of the purchase price therefor by
Federal Funds wire transfer payable to the order of the Company at the offices
of U.S. Bancorp Piper Jaffray Inc., U.S. Bancorp Center, 800 Nicollet Mall,
Minneapolis, Minnesota, or such other location as may be mutually acceptable at
9:00 a.m., Central time, on the Second Closing Date. If the Representatives so
elect, delivery of the Option Shares may be made by credit through full fast
transfer to the accounts at DTC designated by the Representatives. Certificates
representing the Option Shares, in definitive form and in such denominations and
registered in such names as you have set forth in your notice of option
exercise, will be made available for checking and packaging not later than 10:30
a.m., Central time, on the business day next preceding the Second Closing Date
at the office of U.S. Bancorp Piper Jaffray Inc., U.S. Bancorp Center, 800
Nicollet Mall, Minneapolis, Minnesota, or such other location as may be mutually
acceptable.

         (c) It is understood that you, individually and not as Representatives
of the several Underwriters, may (but shall not be obligated to) make payment to
the Company on behalf of any Underwriter for the Securities to be purchased by
such Underwriter. Any such payment by you shall not relieve any such Underwriter
of any of its obligations hereunder. Nothing herein contained shall constitute
any of the Underwriters an unincorporated association or partner with the
Company.


                                       12

         (d) It is understood that the several Underwriters are to make a public
offering of the Firm Shares as soon as the Representatives deem it advisable to
do so. The Firm Shares are to be initially offered to the public at the initial
public offering price set forth in the Prospectus. To the extent, if at all,
that any Option Shares are purchased pursuant to Section 3(b) hereof, the
Underwriters will offer them to the public on the foregoing terms.

         It is further understood that you will act as the Representatives for
the Underwriters in the offering and sale of the Shares in accordance with a
Master Agreement Among Underwriters entered into by you and the several other
Underwriters.

     4.  COVENANTS.

         (a) The Company covenants and agrees with the several Underwriters as
follows:

              (i) If the Registration Statement has not already been declared
     effective by the Commission, then the Company will use its best efforts to
     cause the Registration Statement and any post-effective amendments thereto
     to become effective as soon as possible; the Company will notify you
     promptly of the time when the Registration Statement or any post-effective
     amendment to the Registration Statement has become effective or any
     supplement to the Prospectus (including any term sheet within the meaning
     of Rule 434 of the Rules and Regulations) has been filed, of receipt of any
     comments from the Commission with respect to the Registration Statement or
     Prospectus and of any request by the Commission for any amendment or
     supplement to the Registration Statement or Prospectus or additional
     information; if the Company has elected to rely on Rule 430A of the Rules
     and Regulations, then the Company will prepare and file a Prospectus (or
     term sheet within the meaning of Rule 434 of the Rules and Regulations)
     containing the information omitted therefrom pursuant to Rule 430A of the
     Rules and Regulations with the Commission within the time period required
     by, and otherwise in accordance with the provisions of, Rules 424(b), 430A
     and 434, if applicable, of the Rules and Regulations; if the Company has
     elected to rely upon Rule 462(b) of the Rules and Regulations to increase
     the size of the offering registered under the Act, the Company will prepare
     and file a registration statement with respect to such increase with the
     Commission within the time period required by, and otherwise in accordance
     with the provisions of, Rule 462(b) of the Rules and Regulation; the
     Company will prepare and file with the Commission, promptly upon your
     request, any amendments or supplements to the Registration Statement or
     Prospectus (including any term sheet within the meaning of Rule 434 of the
     Rules and Regulations) that, in your opinion, may be necessary or advisable
     in connection with the distribution of the Securities by the Underwriters;
     and the Company will not file any amendment or supplement to the
     Registration Statement or Prospectus (including any term sheet within the
     meaning of Rule 434 of the Rules and Regulations) to which you shall
     reasonably object by notice to the Company after having been furnished a
     copy a reasonable time prior to the filing.

              (ii) The Company will advise you, promptly after it shall receive
     notice or obtain knowledge thereof, of the issuance by the Commission of
     any stop order suspending the effectiveness of the Registration Statement,
     of the suspension of the 



                                       13
<Page>

     qualification of the Securities for offering or sale in any jurisdiction,
     or of the initiation or threatening of any proceeding for any such purpose;
     and the Company will promptly use its best efforts to prevent the issuance
     of any stop order or suspension of qualification or to obtain the
     withdrawal of any such a stop order, or lifting of any such suspension, if
     issued or imposed.

              (iii) Within the time during which a prospectus relating to the
     Securities is required to be delivered under the Act, the Company will use
     its best efforts to comply as far as it is able with all requirements
     imposed upon it by the Act, as now and hereafter amended, and by the Rules
     and Regulations, as from time to time in force, so far as necessary to
     permit the continuance of sales of or dealings in the Securities as
     contemplated by the provisions hereof and the Prospectus. If during such
     period any event occurs as a result of which the Prospectus would include
     an untrue statement of a material fact or omit to state a material fact
     necessary to make the statements therein, in the light of the circumstances
     then existing, not misleading, or if during such period it is necessary to
     amend the Registration Statement or supplement the Prospectus to comply
     with the Act, the Company will promptly notify you and, subject to Section
     4(a)(i) hereof, will amend the Registration Statement or supplement the
     Prospectus (at the expense of the Company) so as to correct such statement
     or omission or effect such compliance.

              (iv) The Company will use its best efforts to qualify the
     Securities for sale under the securities laws of such jurisdictions as you
     reasonably designate and to continue such qualifications in effect so long
     as required for the distribution of the Securities, except that the Company
     shall not be required in connection therewith to qualify as a foreign
     corporation or to execute a general consent to service of process in any
     state.

              (v) The Company will furnish to the Underwriters copies of the
     Registration Statement (including all exhibits), each Preliminary
     Prospectus, the Prospectus, and all amendments and supplements (including
     any term sheet within the meaning of Rule 434 of the Rules and Regulations)
     to such documents, in each case as soon as available and in such quantities
     as you may from time to time reasonably request.

              (vi) During a period of four (4) years commencing with the date
     hereof, the Company will furnish to the Representatives, and to each
     Underwriter who may so request in writing, copies of all periodic and
     special reports furnished to the stockholders of the Company and all
     information, documents and reports filed with the Commission, the National
     Association of Securities Dealers, Inc., NASDAQ or any securities exchange.

              (vii) The Company will make generally available to its security
     holders, and deliver to you, as soon as practicable, but in any event not
     later than fifteen (15) months after the end of the Company's current
     fiscal quarter, an earnings statement covering a twelve (12) month period
     beginning after the effective date of the Registration Statement that shall
     satisfy the provisions of Section 11(a) of the Act and Rule 158 of the
     Rules and Regulations.

              (viii) The Company, whether or not the transactions contemplated
     hereunder are consummated or this Agreement is prevented from becoming
     effective under the provisions of Section 9(a) hereof or is terminated,
     will pay or cause to be paid (A) all expenses (including transfer taxes
     allocated to the respective transferees) incurred in connection with the
     delivery to the Underwriters of the Securities, (B) all expenses and fees
     (including, without limitation, fees and expenses of the Company's
     accountants and counsel but, except as otherwise provided below, not
     including fees of the Underwriters' counsel) in connection with the
     preparation, printing, filing, delivery, and shipping of the Registration
     Statement (including the financial statements therein and all amendments,
     schedules and exhibits thereto), the Securities, each Preliminary
     Prospectus, the Prospectus, and any amendment thereof or supplement
     thereto, and the printing, delivery, and shipping of this Agreement and
     other underwriting documents, including Blue Sky Memoranda, (C) all filing
     fees and reasonable fees and disbursements of the Underwriters' counsel
     incurred in connection with the qualification of the Securities for
     offering and sale by the Underwriters or by dealers under the securities or
     blue sky laws of the states and other jurisdictions which you shall
     designate in accordance with Section 4(a)(iv) hereof, (D) upon receipt of a
     reasonably detailed accounting, all out-of-pocket expenses, including
     reasonable fees and disbursements of Underwriters' counsel, incurred by the
     Underwriters in administering the Directed Share Program, (E) the fees and
     expenses of any transfer agent or registrar, (F) upon receipt of a
     reasonably detailed accounting, the filing fees and reasonable fees and
     disbursements of the Underwriters' counsel incident to any required review
     by the National Association of Securities Dealers, Inc. of the terms of the
     sale of the Securities, (G) listing fees, if any, and (H) all other costs
     and expenses incident to the performance of its obligations hereunder that
     are not otherwise specifically provided for herein. If the sale of the
     Securities provided for herein is not consummated by reason of action by
     the Company pursuant to Section 9(a) hereof which prevents this Agreement
     from becoming effective, or by reason of any failure, refusal or inability
     on the part of the Company to perform any agreement on its part to be
     performed, or because any condition of the Underwriters' obligations
     hereunder required to be fulfilled by the Company is not fulfilled, the
     Company will reimburse the several Underwriters for all documented
     out-of-pocket disbursements (including documented reasonable fees and
     disbursements of counsel) incurred by the Underwriters in connection with
     their investigation, preparing to market and marketing the Securities or in
     contemplation of performing their obligations hereunder. The Company shall
     not in any event be liable to any of the Underwriters for loss of
     anticipated profits from the transactions covered by this Agreement.

              (ix) The Company will apply the net proceeds from the sale of the
     Securities to be sold by it hereunder for the purposes set forth in the
     Prospectus and will file such reports with the Commission with respect to
     the sale of the Securities and the application of the proceeds therefrom as
     may be required in accordance with Rule 463 of the Rules and Regulations.

              (x) So long as required by law, the Company will furnish to its
     stockholders, and deliver to you, as soon as practicable after the end of
     each fiscal year an annual report (including a balance sheet and statements
     of income, stockholders' equity of 



                                       15

     cash flow of the Company for such fiscal year, accompanied by a copy of the
     certificate or report thereon of nationally recognized independent
     certified public accountants).

              (xi) The Company will furnish to you as early as practicable prior
     to the Closing Date but not later than two (2) business days prior thereto,
     a copy of the latest available quarterly and monthly unaudited interim
     financial statements of the Company which have been read by the Company's
     independent certified public accountants, as stated in their letter to be
     furnished pursuant to Section 5(h) hereof.

              (xii) The Company will not, without the prior written consent of
     U.S. Bancorp Piper Jaffray Inc., from the date of execution of this
     Agreement and continuing to and including the date one hundred and eighty
     (180) days after the date of the Prospectus (the "Lock-Up Period"), sell,
     offer to sell, contract to sell, hypothecate, pledge, grant any option to
     sell, enter into any transaction which is designed to, or might reasonably
     be expected to, result in the disposition (whether by actual disposition or
     effective economic disposition due to cash settlement or otherwise) by the
     Company or any affiliate, or otherwise issue or dispose of, directly or
     indirectly (or publicly disclose the intention to make any such offer,
     sale, pledge, grant, issuance or other disposition), any Common Stock or
     any securities convertible into or exchangeable for, or any options or
     rights to purchase or acquire, Common Stock, or register or publicly
     announce any intent to register under the Act the offer or sale of any
     capital stock of the Company except for (i) the registration of the offer
     and sale of the Securities and sales to the Underwriters pursuant to this
     Agreement; (ii) the issuance of Common Stock upon exercise of options and
     warrants disclosed as outstanding in the Registration Statement and the
     Prospectus; (iii) the issuance of stock options not exercisable during the
     Lock-Up Period pursuant to stock option plans described in the Registration
     Statement and Prospectus; and (iv) registration statements filed on Form
     S-8 limited in scope to stock option plans described in the Registration
     Statement and Prospectus. The Company agrees not to accelerate the vesting
     of any option or warrant or the lapse of any repurchase right prior to the
     expiration of the Lock-Up Period.

              (xiii) The Company either has caused to be delivered to you or
     will cause to be delivered to you prior to the effective date of the
     Registration Statement a binding letter agreement, in the form attached
     hereto as Exhibit D, from each of the Company's directors and officers and
     the holders of more than 90% of the outstanding Common Stock and securities

     otherwise dispose of, directly or indirectly, any shares of Common Stock or
     options, warrants or other rights to purchase Common Stock or any other

     hundred and eighty (180) days after commencement of the public offering of
     the Securities by the Underwriters without the prior written consent of
     U.S. Bancorp Piper Jaffray Inc. Except as set forth in the Prospectus, all

     definitive proxy or information statement required to be filed by the
     Company with the Commission in order to comply with the Exchange Act
     subsequent to the date of the Prospectus and for so long as the delivery of

              (xviii) The Company shall not invest, or otherwise use the
     proceeds received by the Company from its sale of the Securities in such a

     investment company under the Investment Company Act.

              (xix) The Company will not take, directly or indirectly, any
     action designed to cause or result in, or that has constituted or might
     reasonably be expected to constitute, the stabilization or manipulation of

     5. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The obligations of the several
Underwriters hereunder are subject to the accuracy, as of the date hereof and at
each of the First Closing Date and the Second Closing Date (as if made at such
Closing Date), of and compliance with all representations, warranties and
agreements of the Company contained herein, to the performance by the Company of
its obligations hereunder and to the following additional conditions:

         (a) The Registration Statement shall have become effective not later
than 5:00 p.m., Central time, on the date of this Agreement, or such later time
and date as you, as Representatives of the several Underwriters, shall approve
and all filings required by Rules 424, 430A and 434 of the Rules and Regulations
shall have been timely made; no stop order suspending the effectiveness of the
Registration Statement or any amendment thereof shall have been issued; no
proceedings for the issuance of such an order shall have been initiated or
threatened; and any request of the Commission for additional information (to be
included in the Registration Statement or the Prospectus or otherwise) shall
have been complied with to your satisfaction.


                                       17
<Page>

         (b) No Underwriter shall have advised the Company that the Registration
Statement or the Prospectus, or any amendment thereof or supplement thereto
(including any term sheet within the meaning of Rule 434 of the Rules and
Regulations), contains an untrue statement of fact which, in your opinion, is
material, or omits to state a fact which, in your opinion, is material and is
required to be stated therein or necessary to make the statements therein not
misleading.

         (c) Except as specifically set forth in the Prospectus, subsequent to
the respective dates as of which information is given in the Registration
Statement and the Prospectus, neither the Company nor any Subsidiary shall have
incurred any material liabilities or obligations, direct or contingent, or
entered into any material transactions, or declared or paid any dividends or
made any distribution of any kind with respect to its capital stock; and there
shall not have been any change in the capital stock (other than a change in the
number of outstanding shares of Common Stock due to the issuance of shares upon
the exercise of outstanding options or warrants disclosed as outstanding in the
Registration Statement and Prospectus), or any material change in the short-term
or long-term debt of the Company or any Subsidiary, or any issuance of options,
warrants, convertible securities or other rights to purchase the capital stock
of the Company or any Subsidiary, or any change which has or is reasonably
possible to have a Material Adverse Effect, or any development involving or
which has or is reasonably possible to have a prospective Material Adverse
Effect, that, in your judgment, makes it impractical or inadvisable to offer or
deliver the Securities on the terms and in the manner set forth in the
Prospectus.

         (d) On each Closing Date, there shall have been furnished to you, as 
Representatives of the several Underwriters, the opinion of Cooley Godward 
LLP, counsel for the Company, dated such Closing Date and addressed to you, 
covering the matters set forth in Schedule II.

         (e) On each Closing Date, there shall have been furnished to you, as
Representatives of the several Underwriters, the opinion of Townsend and
Townsend and Crew L.L.P., special counsel for the Company with respect to patent
and proprietary rights, dated such Closing Date and addressed to you, with
reproduced copies for each of the other Underwriters and in form reasonably
satisfactory to Preston Gates & Ellis LLP, counsel for the Underwriters, stating
that:

              (i) To such counsel's knowledge, except as described in the
     Prospectus, (A) the Company has valid license rights or clear title to the
     Intellectual Property referenced in the Prospectus, and there are no rights
     of third parties to any such Intellectual Property; (B) there is no
     infringement or other violation by third parties of any of the Intellectual
     Property of the Company referenced in the Prospectus; (C) there is no
     infringement or other violation by the Company of any Intellectual Property
     of others; (D) there is no pending or threatened action, suit, proceeding
     or claim by governmental authorities or others that the Company infringes
     or otherwise violates any Intellectual Property of others, and such counsel
     is unaware of any facts which would form a reasonable basis for any such
     claim; and (E) there is no pending or threatened action, suit, proceeding
     or claim by governmental authorities or others challenging the rights of
     the Company in or to, or challenging the scope of, any Intellectual
     Property of the Company


                                       18
<Page>


     referenced in the Prospectus, and such counsel is unaware of any facts
     which would form a reasonable basis for any such claim.

              (ii) To such counsel's knowledge, the patent applications of the
     Company presently on file disclose patentable subject matter, and such
     counsel is not aware of any inventorship challenges, any interference which
     has been declared or provoked, or any other material fact with respect to
     the patent applications of the Company presently on file that (A) would
     preclude the issuance of patents with respect to such applications or (B)
     would lead such counsel to conclude that such patents, when issued, would
     not be valid and enforceable in accordance with applicable regulations.

              (iii) Such counsel has reviewed the portions of the Registration
     Statement and the Prospectus referencing certain Company patent rights,
     captioned "Risk Factors--Our failure to protect our intellectual property
     rights could adversely affect our ability to compete," "Risk
     Factors--Intellectual property or product liability claims against us could
     harm our competitive position, results of operations and financial
     condition" and "Business--Proprietary Rights and Licensing" (collectively,
     the "Patent Sections"). On the basis of such counsel's representation of
     the Company, such counsel has no reason to believe that the information in
     the Patent Sections contains any untrue statement or material fact or omits
     to state a material fact necessary to make the statements therein not
     misleading and insofar as such Patent Sections constitute statements or
     summaries of matters of law, to such counsel's knowledge, are, in all
     material respects, accurate and complete statements or summaries, as the
     case may be, of the matters referred to therein.

         (f) On each Closing Date, there shall have been furnished to you, as
Representatives of the several Underwriters, the opinion of Preston Gates &
Ellis LLP, counsel for the several Underwriters, dated such Closing Date and
addressed to you, with respect to the formation of the Company, the validity of
the Securities and other related matters as you reasonably may request, and such
counsel shall have received such papers and information as they request to
enable them to pass upon such matters.

         (g) On each Closing Date, there shall have been furnished to you, as
Representatives of the several Underwriters, a letter of Ernst & Young LLP,
dated such Closing Date and addressed to you, confirming that they are
independent public accountants within the meaning of the Act and are in
compliance with the applicable requirements relating to the qualifications of
accountants under Rule 2-01 of Regulation S-X of the Commission, and stating, as
of the date of such letter (or, with respect to matters involving changes or
developments since the respective dates as of which specified financial
information is given in the Prospectus, as of a date not more than five (5) days
prior to the date of such letter), stating that in their opinion the financial
statements and schedules examined by them and included in the Registration
Statement and Prospectus comply in form in all material respects with the
applicable accounting requirements of the Act and the related published Rules
and Regulations; and containing such other statements and information as is
ordinarily included in accountants' "comfort letters" to Underwriters with
respect to the financial statements and certain financial and statistical
information contained in the Registration Statement and Prospectus and that the
conclusions and findings of said firm with respect to the financial information
and other matters covered by their letter delivered to you 



                                       19
<Page>

concurrently with the execution of this Agreement, and the effect of the letter
so to be delivered on such Closing Date shall be to confirm the conclusions and
findings set forth in such prior letter.

         (h) On each Closing Date, there shall have been furnished to you, as
Representatives of the Underwriters, a certificate, dated such Closing Date and
addressed to you, signed by the chief executive officer and by the chief
financial officer of the Company, stating that:

              (i) The representations and warranties of the Company in this
     Agreement are true and correct in all material respects as if made at and
     as of such Closing Date, and the Company has complied with all the
     agreements and satisfied all the conditions on its part to be performed or
     satisfied at or prior to such Closing Date.

              (ii) No stop order or other order suspending the effectiveness of
     the Registration Statement or any amendment thereof or the qualification of
     the Securities for offering or sale has been issued, and no proceeding for
     that purpose has been instituted or, to their knowledge or the knowledge of
     the Company, is contemplated by the Commission or any state or regulatory
     body.

              (iii) The signers of said certificate have carefully examined the
     Registration Statement and the Prospectus, and any amendments thereof or
     supplements thereto (including any term sheet within the meaning of Rule
     434 of the Rules and Regulations), and (A) such documents contain all
     statements and information required to be included therein, the
     Registration Statement, or any amendment thereof, does not contain any
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, and the Prospectus, as amended or supplemented, does not
     include any untrue statement of material fact or omit to state a material
     fact necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading, (B) since the
     effective date of the Registration Statement, there has occurred no event
     required to be set forth in an amended or supplemented prospectus which has
     not been so set forth, (C) subsequent to the respective dates as of which
     information is given in the Registration Statement and the Prospectus,
     neither the Company nor any Subsidiary has incurred any material
     liabilities or obligations, direct or contingent, or entered into any
     material transactions, or declared or paid any dividends or made any
     distribution of any kind with respect to its capital stock; and there has
     not been any change in the capital stock (other than a change in the number
     of outstanding shares of Common Stock due to the issuance of shares upon
     the exercise of outstanding options or warrants disclosed as outstanding in
     the Registration Statement and Prospectus), or any material change in the
     short-term or long-term debt of the Company or any Subsidiary, or any
     issuance of options, warrants, convertible securities or other rights to
     purchase the capital stock, of the Company or any Subsidiary, or any change
     that would have a Material Adverse Effect or any development involving a
     prospective Material Adverse Effect and (D) except as stated in the
     Registration Statement and the Prospectus, there is not pending or, to
     their knowledge, threatened or contemplated, any action, suit or proceeding
     to which the Company, any Subsidiary or any of their respective officers is
     a party before or by any court or 


                                       20
<Page>

     governmental agency, authority or body, or any arbitrator, which might
     result in a Material Adverse Effect.

              (iv) All filings required to have been made pursuant to Rules 424
     or 430A under the Act have been made.

              (v) The lock-up agreements described in Section 4(a)(xiii) have
     not been terminated or modified by the Company in any material respects.

         (i) The Securities shall have been approved for listing for quotation
on the Nasdaq National Market, subject only to notice of issuance at or prior to
the Closing Date.

         (j) The Company shall have furnished to you and counsel for the
Underwriters such additional documents, certificates and evidence as you or they
may have reasonably requested.

         (k) The Representatives shall have received at or prior to the First
Closing Date from Preston Gates & Ellis LLP, a memorandum or summary, in form
and substance satisfactory to the Representatives, with respect to the
qualification for offering and sale by the Underwriters of the Securities under
the State securities or Blue Sky laws of such jurisdictions as the
Representatives may reasonably have designated to the Company.

     All such opinions, certificates, letters and other documents referred to
hereinabove will be in compliance with the provisions hereof only if they are
satisfactory in form and substance to you and counsel for the Underwriters. The
Company will furnish you with such conformed copies of such opinions,
certificates, letters and other documents as you shall reasonably request.

     6. INDEMNIFICATION AND CONTRIBUTION.

         (a) The Company agrees to indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise (including in
settlement of any litigation if such settlement is effected with the written
consent of the Company), insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon an untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement, including the information deemed to be a part of the
Registration Statement at the time of effectiveness pursuant to Rules 430A and
434(d) of the Rules and Regulations, if applicable, any Preliminary Prospectus,
the Prospectus, or any amendment or supplement thereto (including any term sheet
within the meaning of Rule 434 of the Rules and Regulations), or in any
materials or information provided to investors by, or with the approval of, the
Company in connection with the marketing of the offering of the Common Stock
("Marketing Materials"), including any roadshow or investor presentations made
to investors by the Company (whether in person or electronically) or arise out
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein in light of the circumstances in which they were made, not misleading,
and will reimburse each Underwriter for any legal or other expenses reasonably
incurred by it in connection with investigating or defending against such loss,
claim, damage, liability or action; provided, however, that (i) the Company
shall not be liable in any such case to the extent that any such 



                                       21
<Page>

loss, claim, damage, liability or action arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in the Registration Statement, any Preliminary Prospectus, the Prospectus,
or any such amendment or supplement, or in any Marketing Materials, in reliance
upon and in conformity with written information furnished to the Company by you,
or by any Underwriter through you, specifically for use in the preparation
thereof and (ii) the foregoing indemnity with respect to any Preliminary
Prospectus shall not inure to the benefit of any Underwriter from whom the
person asserting any such loss, damage, liability or claim purchased Shares, or
any person controlling such Underwriter, if a copy of the Prospectus (as then
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Underwriter
to such person, if required by law to have been so delivered at or prior to the
written confirmation of the sale of the Shares to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, damage, liability or claim, and the Company had previously
furnished copies thereof to such Underwriter.

     The Company further agrees to indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise (including in
settlement of any litigation if such settlement is effected with the written
consent of the Company), insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon or in connection
with the offer and sale of the Reserved Shares under the Directed Share Program,
provided that the Company shall not be responsible for any loss, damage,
expense, liability or claim that is finally judicially determined to have
resulted from the bad faith or gross negligence of the Underwriters in
conducting the Directed Share Program.

     In addition to its other obligations under this Section 6(a), the Company
agrees that, as an interim measure during the pendency of any claim, action,
investigation, inquiry or other proceeding arising out of or based upon any
statement or omission, or any alleged statement or omission, described in this
Section 6(a), or the offer and sale of the Reserved Shares under the Directed
Share Program, it will reimburse each Underwriter on a monthly basis for all
reasonable legal fees or other expenses incurred in connection with
investigating or defending any such claim, action, investigation, inquiry or
other proceeding, notwithstanding the absence of a judicial determination as to
the propriety and enforceability of the Company's obligation to reimburse the
Underwriters for such expenses and the possibility that such payments might
later be held to have been improper by a court of competent jurisdiction. To the
extent that any such interim reimbursement payment is so held to have been
improper, the Underwriter that received such payment shall promptly return it to
the party or parties that made such payment, together with interest, compounded
daily, determined on the basis of the prime rate (or other commercial lending
rate for borrowers of the highest credit standing) announced from time to time
by U.S. Bancorp (the "Prime Rate"). Any such interim reimbursement payments
which are not made to an Underwriter within thirty (30) days of a request for
reimbursement shall bear interest at the Prime Rate from the date of such
request. This indemnity agreement shall be in addition to any liabilities which
the Company may otherwise have.

         (b) In connection with the offer and sale of the Reserved Shares, the
Company agrees to purchase from U.S. Bancorp Piper Jaffray Inc., at its request,
for full purchase price all Reserved Shares not resold by the Underwriters which
were subject to a properly confirmed 



                                       22
<Page>

agreement to purchase and for which any Directed Share Participant failed to pay
therefor and accept delivery thereof.

         (c) Each Underwriter will indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company, each of
its directors and each officer who signed the Registration Statement, and each
person, if any, who controls the Company within the meaning of Section 5 of the
Act against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of such
Underwriter), insofar as such Losses (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement, any Preliminary
Prospectus, the Prospectus, or any amendment or supplement thereto (including
any term sheet within the meaning of Rule 434 of the Rules and Regulations), or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in the Registration Statement, any Preliminary
Prospectus, the Prospectus, or any such amendment or supplement, in reliance
upon and in conformity with written information furnished to the Company by you,
or by such Underwriter through you, specifically for use in the preparation
thereof, and will reimburse the Company for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending
against any such loss, claim, damage, liability or action. Notwithstanding the
provisions of this subsection (c), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the Securities underwritten by it and distributed to the public were offered to
the public exceeds the amount of any damages that such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (c) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

         (d) Promptly after receipt by an indemnified party under subsection (a)
or (c) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve the indemnifying party from any liability that it may have to any
indemnified party to the extent the indemnifying party is not materially
prejudiced thereby. In case any such action shall be brought against any
indemnified party, and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
in, and, to the extent that it shall wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of the indemnifying party's election so to
assume the defense thereof, the indemnifying party shall not be liable to such
indemnified party under such subsection for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
if, in the sole judgment of the 


                                       23
<Page>

Representatives, it is advisable for the Underwriters to be represented as a
group by separate counsel, the Representatives shall have the right to employ a
single counsel to represent the Representatives and all Underwriters who may be
subject to liability arising from any claim in respect of which indemnity may be
sought by the Underwriters under subsection (a) of this Section 6, in which
event the reasonable fees and expenses of such separate counsel shall be borne
by the indemnifying party or parties and reimbursed to the Underwriters as
incurred (in accordance with the provisions of the second paragraph in
subsection (a) above). Notwithstanding anything contained herein to the
contrary, if indemnity may be sought pursuant to the second full paragraph of
subsection 6(a) hereof in respect of such action or proceeding, then the
indemnifying party shall be liable for the reasonable fees and expenses of not
more than one separate firm for the Underwriters for the defense of any losses,
claims, damages and liabilities arising out of the Directed Share Program, and
all persons, if any, who control each Underwriter within the meaning of the Act.
An indemnifying party shall not be obligated under any settlement agreement
relating to any action under this Section 6 to which it has not agreed in
writing.

         (e) If the indemnification provided for in this Section 6 is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (c) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (c) above, (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company on the one hand and the Underwriters on the other from the
offering of the Securities or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and the Underwriters on
the other in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Company bear to the total underwriting discounts and commissions received
by the Underwriters, in each case as set forth in the table on the cover page of
the Prospectus. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Underwriters and the parties'
relevant intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The Company and the Underwriters
agree that it would not be just and equitable if contributions pursuant to this
subsection (e) were to be determined by pro rata allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to in the first sentence of this subsection (e). The amount paid by an
indemnified party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this subsection (e) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending against any action or claim
which is the subject of this subsection (e). Notwithstanding the provisions of
this subsection (e), no Underwriter shall be required to contribute any amount
in excess of the amount by which the total price at which the Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been


                                       24
<Page>

required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations in this subsection (e) to contribute are several in
proportion to their respective underwriting obligations and not joint.

         (f) The obligations of the Company under this Section 6 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 6 shall be in addition to any liability that the
respective Underwriters may otherwise have and shall extend, upon the same terms
and conditions, to each director of the Company (including any person who, with
his consent, is named in the Registration Statement as about to become a
director of the Company), to each officer of the Company who has signed the
Registration Statement and to each person, if any, who controls the Company
within the meaning of the Act.

     7. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. All representations,
warranties, and agreements of the Company herein or in certificates delivered
pursuant hereto, and the agreements of the several Underwriters and the Company
contained in Section 6 hereof, shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of any Underwriter
or any controlling person thereof, or the Company or any of its officers,
directors, or controlling persons, and shall survive delivery of, and payment
for, the Securities to and by the Underwriters hereunder.

     8. SUBSTITUTION OF UNDERWRITERS.

         (a) If any Underwriter or Underwriters shall fail to take up and pay
for the amount of Firm Shares agreed by such Underwriter or Underwriters to be
purchased hereunder, upon tender of such Firm Shares in accordance with the
terms hereof, and the amount of Firm Shares not purchased does not aggregate
more than ten percent (10%) of the total amount of Firm Shares set forth in
Schedule I hereto, the remaining Underwriters shall be obligated to take up and
pay for (in proportion to their respective underwriting obligations hereunder as
set forth in Schedule I hereto except as may otherwise be determined by you) the
Firm Shares that the withdrawing or defaulting Underwriters agreed but failed to
purchase.

         (b) If any Underwriter or Underwriters shall fail to take up and pay
for the amount of Firm Shares agreed by such Underwriter or Underwriters to be
purchased hereunder, upon tender of such Firm Shares in accordance with the
terms hereof, and the amount of Firm Shares not purchased aggregates more than
ten percent (10%) of the total amount of Firm Shares set forth in Schedule I
hereto, and arrangements satisfactory to you for the purchase of such Firm
Shares by other persons are not made within thirty-six (36) hours thereafter,
this Agreement shall terminate. In the event of any such termination, the
Company shall not be under any liability to any Underwriter (except to the
extent provided in Section 4(a)(viii) and Section 6 hereof) nor shall any
Underwriter (other than an Underwriter who shall have failed, otherwise than for
some reason permitted under this Agreement, to purchase the amount of Firm
Shares agreed by such Underwriter to be purchased hereunder) be under any
liability to the Company (except to the extent provided in Section 6 hereof).


                                       25

     If Firm Shares to which a default relates are to be purchased by the
non-defaulting Underwriters or by any other party or parties, the
Representatives or the Company shall have the right to postpone the First
Closing Date for not more than seven (7) business days in order that the
necessary changes in the Registration Statement, Prospectus and any other
documents, as well as any other arrangements, may be effected. As used herein,

this Section 8. Any action taken under this Section 8 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

     9. EFFECTIVE DATE OF THIS AGREEMENT AND TERMINATION.

         (a) This Agreement shall become effective at 10:00 a.m., Central time,

occur. By giving notice as hereinafter specified before the time this Agreement
becomes effective, you, as Representatives of the several Underwriters, or the
Company may prevent this Agreement from becoming effective without liability of
any party to any other party, except that the provisions of Section 4(a)(viii)
and Section 6 hereof shall at all times be effective.

         (b) You, as Representatives of the several Underwriters, shall have the
right to terminate this Agreement by giving notice as hereinafter specified at
any time at or prior to the First Closing Date, and the option referred to in
Section 3(b), if exercised, may be cancelled at any time prior to the Second
Closing Date, if (i) the Company shall have failed, refused or been unable, at
or prior to such Closing Date, to perform any agreement on its part to be
performed hereunder, (ii) any condition of the Underwriters' obligations
hereunder is not fulfilled, (iii) trading on the New York Stock Exchange, the
American Stock Exchange or the Nasdaq National Market shall have been wholly
suspended, (iv) minimum or maximum prices for trading shall have been fixed, or
maximum ranges for prices for securities shall have been required, on the New
York Stock Exchange, the American Stock Exchange or the Nasdaq National Market,
by such Exchange or by order of the Commission or any other governmental
authority having jurisdiction, (v) a banking moratorium shall have been declared
by Federal, New York or California authorities, (vi) since the respective dates
as of which information is given in the Registration Statement and the
Prospectus, any material adverse change or any development that would reasonably
be expected to result in a material adverse change in or affecting the
condition, financial or otherwise, of the Company and its Subsidiaries taken as
a whole or the earnings, business, management, properties, assets, rights,
operations, condition (financial or otherwise) or prospects of the Company and
its Subsidiaries taken as a whole, whether or not arising in the ordinary course
of business, that, in your judgment, makes it impractical or inadvisable to
proceed with the completion of the sale of and payment for the Securities, (vii)
the enactment, publication, decree or other promulgation of any statute,
regulation, rule or order of any court or other governmental authority which in
your opinion materially and adversely affects or may 


                                       26
<Page>

materially and adversely affect the business or operations of the Company that,
in your judgment, makes it impractical or inadvisable to proceed with the
completion of the sale of and payment for the Securities, or (viii) there has
occurred any material adverse change in the financial markets in the United
States or an outbreak of major hostilities (or an escalation thereof) in which
the United States is involved, a declaration of war by Congress, any other
substantial national or international calamity or any other event or occurrence
of a similar character shall have occurred since the execution of this Agreement
that, in your judgment, makes it impractical or inadvisable to proceed with the
completion of the sale of and payment for the Securities. Any such termination
shall be without liability of any party to any other party except that the
provisions of Section 4(a)(viii) and Section 6 hereof shall at all times be
effective.

         (c) If you elect to prevent this Agreement from becoming effective or
to terminate this Agreement as provided in this Section, the Company shall be
notified promptly by you by telephone or telegram, confirmed by letter. If the
Company elects to prevent this Agreement from becoming effective, you shall be
notified by the Company by telephone or telegram, confirmed by letter.

     10. DEFAULT BY THE COMPANY. If the Company shall fail at the First Closing
Date to sell and deliver the number of Securities which it is obligated to sell
hereunder, then this Agreement shall terminate without any liability on the part
of any non-defaulting party. No action taken pursuant to this Section shall
relieve the Company from liability, if any, in respect of such default.

               AMENDED AND RESTATED ARTICLES OF INCORPORATION
                                 OF OMNICELL.COM



Sheldon D. Asher and Robert J. Brigham certify that:

     1. They are the President and Chief Executive Officer and Secretary,
respectively, of OMNICELL.COM, a California corporation.

     2. The Board of Directors of the Corporation duly approved the following
amendment to the Corporation's Amended and Restated Articles of Incorporation:

     A new final paragraph of Article III shall be added to read in its entirety
     as follows:

          "The Common Stock shall be divided upon the filing of this Certificate
     of Amendment, every one and six tenths (1.6) shares of Common Stock
     outstanding shall be combined and reconstituted into one (1) share of
     Common Stock; provided, however, that the Corporation shall issue no
     fractional shares of Common Stock, but shall instead pay to any stockholder
     who would be entitled to receive a fractional share as a result of the
     actions set forth herein a sum in cash equal to the fair market value of
     such fractional share."

     3. Thereafter pursuant to a resolution of the Board of Directors, this
Certificate of Amendment was submitted to the stockholders of the Corporation
for their approval, and was approved,
 in accordance with Section 902 of the
California Corporations Code. The total number of outstanding shares of Common
Stock of the Corporation is 5,212,957, and the total number of outstanding
shares of (i) Series A Preferred is 480,000, (ii) Series B Preferred is 320,666,
(iii) Series C Preferred is 1,700,000, (iv) Series D Preferred is 1,309,484, (v)
Series E Preferred is 1,965,262, (vi) Series F Preferred is 1,948,090, (vii)
Series G Preferred is zero, (viii) Series H Preferred is 3,804,346, (ix) Series
I Preferred is zero, (x) Series J Preferred is 720,800 and (xi) Series K
Preferred is 3,010,528. The number of shares voting in favor of Amendment and
Restatement equaled or exceeded the vote required. The percentage vote required
was (i) more than 50% of the Common Stock voting as a class and (ii) more than
50% of the Preferred Stock voting together as a class.

     4. All other provisions of the Amended and Restated Articles shall
remain in full force and effect.

                                       1.

                          OMNICELL MERGER CORPORATION.


                                       I.

         The name of this corporation is Omnicell Merger Corporation.

                                       II.

         The address of the registered office of the corporation in the State of
Delaware is 1013 Centre Road, City of Wilmington, 19805, County of New Castle
and the name of the registered agent of the corporation in the State of Delaware
at such address is Corporation Service Company.

                                      III.

         The purpose of the Corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.

                                       IV.

         The Corporation is authorized to issue two classes of shares to be
designated respectively Common Stock and Preferred Stock. The total number of
shares of Common Stock the Corporation shall have authority to issue is
50,000,000, each having a par value of one-tenth of one cent ($.001) and the
total number of shares of Preferred Stock the Corporation shall have authority
to issue is 22,754,561, each having a par value of one-tenth of one cent
($.001).

         The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized to fix the number of shares
of any series
 of Preferred Stock and, subject to the rights of existing
stockholders set forth in Article V, Section 6, to determine or alter the
rights, preferences, privileges and restrictions granted to or imposed upon any
wholly unissued series of Preferred Stock and, within the limits and
restrictions stated in any resolution or resolutions of the Board of Directors
originally fixing the number of shares constituting any series of Preferred
Stock, to increase or decrease (but not below the number of shares of any such
series then outstanding) the number of shares of any such series subsequent to
the issue of shares of that series (subject to the provisions of Section 6 of
Article V hereof).

         The Common Stock shall be divided into two series, to be designated,
respectively, Class A Voting Common Stock, consisting of 47,500,000 shares
("Class A Common"), and Class B Non-voting Common Stock, consisting of 2,500,000
shares ("Class B Common").

         The first series of Preferred Stock shall be designated Series A
Preferred Stock ("Series A Preferred") and shall consist of 480,000 shares. The
second series of Preferred Stock shall be designated Series B Preferred Stock
("Series B Preferred") and shall consist of 320,666 shares. The third series of
Preferred Stock shall be designated Series C Preferred Stock ("Series C
Preferred") and shall consist of 1,700,000 shares. The fourth series of
Preferred Stock shall be designated Series D Preferred Stock ("Series D
Preferred") and shall consist of 1,328,000 shares. The fifth series of Preferred
Stock shall be designated Series E Preferred Stock ("Series E Preferred") and
shall consist of 1,966,000 shares. The 


<PAGE>

sixth series of Preferred Stock shall be designated Series F Preferred Stock
("Series F Preferred") and shall consist of 2,000,000 shares. The seventh series
of Preferred Stock shall be designated Series G Preferred Stock ("Series G
Preferred") and shall consist of 1,000,000 shares. The eighth series of
Preferred Stock shall be designated Series H Preferred Stock ("Series H
Preferred") and shall consist of 4,000,000 shares. The ninth series of Preferred
Stock shall be designated Series J Preferred Stock ("Series J Preferred") and
shall consist of 1,802,000 shares. The tenth series of Preferred Stock shall be
designated Series K Preferred Stock ("Series K Preferred") and shall consist of
3,157,895 shares. The remaining 5,000,000 shares of Preferred Stock are not yet
designated. The Series A Preferred, the Series B Preferred, the Series C
Preferred, the Series D Preferred, the Series E Preferred, the Series F
Preferred, Series G Preferred, Series H Preferred, Series J Preferred, and
Series K Preferred shall be referred to as the "Preferred."

                                       V.

The relative rights, preferences, privileges and restrictions granted to or
imposed on the respective classes of the shares of capital stock or the holders
thereof are as follows:

         1.     DIVIDENDS.

                (a)     The holders of the Series J Preferred shall be 
entitled to receive in any fiscal year, when and as declared by the Board of 
Directors, out of any assets legally available therefore, dividends in cash 
at an annual rate of $1.12 per share (as adjusted for any stock dividends, 
combinations, consolidations or splits with respect to such shares). The 
right to such dividends shall not be cumulative and no right shall accrue to 
holders of Series J Preferred by reason of the fact that dividends on such 
shares were not declared in any prior year, nor shall any undeclared 
dividends bear or accrue interest. Such dividends shall be prior and in 
preference to any declaration or payment of any dividend, (payable other than 
in common stock) on the Series A Preferred, Series B Preferred, Series C 
Preferred, Series D Preferred, Series E Preferred, Series F Preferred, Series 
G Preferred, Series H Preferred, Series K Preferred, or Common Stock. No 
dividend may be paid on the Series A Preferred, the Series B Preferred, the 
Series C Preferred, the Series D Preferred, the Series E Preferred, the 
Series F Preferred, the Series G Preferred, the Series H Preferred, the 
Series K Preferred, or the Common Stock unless and until any and all 
dividends have been paid to the Series J Preferred.

                (b)     After payment of all required dividends required to 
the holders of Series J Preferred, the holders of outstanding Series A 
Preferred, Series B Preferred, Series C Preferred, Series D Preferred, Series 
E Preferred, Series F Preferred, Series G Preferred, Series H Preferred, and 
Series K Preferred shall be entitled to receive in any fiscal year, when and 
as declared by the Board of Directors, out of any assets at the time legally 
available therefor, dividends in cash at an annual rate of $0.02 per share of 
Series A Preferred, $0.03 per share of Series B Preferred, $0.048 per share 
of Series C Preferred, $0.085 per share of Series D Preferred, $0.265 per 
share of Series E Preferred, $0.49 per share of Series F Preferred, $0.49 per 
share of Series G Preferred, $0.29 per share of Series H Preferred, $0.76 per 
share of Series K Preferred (as adjusted for any stock dividends, 
combinations, consolidations or splits with respect to such shares). Such 
dividends may be payable quarterly or otherwise as the Board of Directors may 
from time to time determine. The right to such dividends shall not be 
cumulative and no right shall accrue to holders of such Preferred by reason 
of the fact that dividends on such shares were not declared in any prior 
year, nor shall any undeclared dividends bear or accrue interest.

                (c)     Any partial payment of such dividends to the holders 
of the Series A Preferred, Series B Preferred, Series C Preferred, Series D 
Preferred, Series E Preferred, Series F Preferred, Series G Preferred, Series 
H Preferred and Series K Preferred shall be made in proportion to the

                                       2.

<PAGE>

amount each such holder would be entitled to receive as set forth above if such
amounts were paid in full. Dividends other than dividends payable solely in
Common Stock may be declared or paid upon shares of Common Stock in any fiscal
year of the Corporation only if dividends at the annual rates set forth above
shall have been paid or declared and set apart upon all shares of Preferred for
such fiscal year. No dividend shall be declared or paid with respect to the
Common Stock unless at the same time an equivalent dividend is declared or paid
with respect to the Preferred on an as-if-converted to Common Stock basis. Any
declared but unpaid dividends on the Preferred shall be paid upon the conversion
of such shares into Common Stock either (at the option of the Corporation) by
payment of cash or by the issuance of additional shares of Common Stock based
upon the fair market value of the Common Stock at the time of conversion, as
determined by the Board of Directors. No dividend payable in Common Stock shall
be declared or paid with respect to any series of Preferred unless at the same
time a similar dividend is declared or paid to all series of Preferred on an
as-if-converted to Common Stock basis, such that the holders of no series of
Preferred shall hold a greater proportion of the Corporation's Common Stock
following such dividend (on an as-if converted basis) than immediately prior to
such dividend.

         2.     LIQUIDATION PREFERENCE. In the event of any liquidation,
dissolution, or winding up of the Corporation, either voluntary or involuntary,
distributions to the stockholders of the Corporation shall be made in the
following manner:

                (a)     Holders of the Series J Preferred shall be entitled 
to receive, prior and in preference to any distribution of any of the assets 
or surplus funds of the Corporation to the holders of the Series A Preferred, 
Series B Preferred, Series C Preferred, Series D Preferred, Series E 
Preferred, Series F Preferred, Series G Preferred, Series H Preferred, Series 
K Preferred or Common Stock by reason of their ownership thereof, the amount 
of $14.03274 per share (as adjusted for any stock dividends, combinations, 
consolidations or splits with respect to such shares), plus all accrued or 
declared but unpaid dividends on such share for each share of Series J 
Preferred then held by them. If the assets and funds thus distributed among 
the holders of Series J Preferred shall be insufficient to permit the payment 
to such holders of the full aforesaid preferential amount, then the entire 
assets and funds of the Corporation legally available for distribution shall 
be distributed among the holders of Series J Preferred in proportion to the 
full preferential amount each such holder is otherwise entitled to receive.

                (b)     Subject to the payment in full of the liquidation 
preferences with respect to the Series J Preferred as provided in Section 
2(a) above, the holders of the Series A Preferred, Series B Preferred, Series 
C Preferred, Series D Preferred, Series E Preferred, Series F Preferred, 
Series G Preferred, Series H Preferred and Series K Preferred shall be 
entitled to receive, prior and in preference to any distribution of any of 
the assets or surplus funds of the Corporation to the holders of the Common 
Stock by reason of their ownership of such stock, the amount of $0.25 per 
share for each share of Series A Preferred then held by them, $0.375 per 
share for each share of Series B Preferred then held by them, $0.60 per share 
for each share of Series C Preferred then held by them, $1.085 per share for 
each share of Series D Preferred then held by them, $3.30 per share of Series 
E Preferred then held by them, $6.15 per share of Series F Preferred then 
held by them, $6.15 per share of Series G Preferred then held by them, $3.68 
per share of Series H Preferred then held by them, for the holders of Series 
K Preferred, the greater of (i) $9.50 per share of Series K Preferred, then 
held by such holder and (ii) the amount per share of Series K Preferred, that 
such holder would have received if they had converted their Series K 
Preferred shares into Common Stock immediately prior to the liquidation, 
adjusted for any stock dividends, combinations, consolidations, or splits 
with respect to such shares and, in addition, an amount equal to all declared 
but unpaid dividends on the Series A Preferred, Series B Preferred, Series C 
Preferred, Series D Preferred, Series E Preferred, Series F Preferred, Series 
G Preferred, Series H Preferred and Series K Preferred. If the assets and 
funds thus distributed among the holders of Preferred shall be insufficient 
to permit the payment to such holders of the full aforesaid preferential 
amount, then the entire assets and funds of the Corporation remaining after 
payment in full of the liquidation preference set forth in Section 2(a) and 
legally available for distribution shall be distributed among the holders of 
Preferred in proportion to the full preferential amount each such holder is 
otherwise entitled to receive. After payment has been made to the holders of 
Preferred of the full

                                       3.

<PAGE>

amounts to which they shall be entitled as aforesaid, the holders of the Common
Stock shall be entitled to receive ratably on a per-share basis all the
remaining assets.

                (c)     For purposes of this Section 2, a merger or
consolidation of the Corporation with or into any other corporation or
corporations, or the merger of any other corporation or corporations into the
Corporation, in which the stockholders of the Corporation receive distributions
in cash or securities of another corporation or corporations as a result of such
consolidation or merger, any transaction or series of related transactions to
which the Company is a party in which excess of fifty percent (50%) of the
Company's voting power is transferred, or a sale of all or substantially all of
the assets of the Corporation (collectively, a "Change in Control"), shall be
treated as a liquidation, dissolution or winding up of the Corporation.

         Any securities to be delivered to the holders of the Preferred pursuant
to this subsection (c) shall be valued as follows:

                        (i)     Securities not subject to investment letter or
other similar restrictions on free marketability:

                                (A)     If traded on a securities exchange or
the Nasdaq National Market System, the value shall be deemed to be the average
of the closing prices of the securities on such exchange or system over the
30-day period ending three (3) days prior to the closing;

                                (B)     If actively traded over-the-counter, the
value shall be deemed to be the average of the closing bid prices over the
30-day period ending three (3) days prior to the closing; and

                                (C)     If there is no active public market, the
value shall be the fair market value thereof, as determined in good faith by the
Board of Directors of the Corporation.

                        (ii)    The method of valuation of securities subject 
to investment letter or other restrictions on free marketability shall be to 
make an appropriate discount from the market value determined as above in 
(i)(A), (B) or (C) to reflect the approximate fair market value thereof, as 
determined in good faith by the Board of Directors of the Corporation.

         The Corporation shall give each holder of record of shares of Preferred
written notice of an impending transaction described in this subsection 2(c) not
later than twenty (20) days prior to the stockholders meeting called to approve
such transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this section 2(c) and the Corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after the Corporation has given the first notice
provided for herein or sooner than ten (10) days after the corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened upon the written consent of the holders of shares of
Preferred Stock which is entitled to such notice rights or similar notice rights
and which represents at least a majority of the voting power of all then
outstanding shares of such shares of Preferred Stock.

                (d) As authorized by Section 402.5(c) of the California
Corporations Code, the provisions of Sections 502 and 503 of the California
Corporations Code shall not apply with respect to repurchase by the Corporation
of shares of Common Stock issued to or held by employees or consultants


                                       4.

<PAGE>

of the Corporation or its subsidiaries upon termination of their employment or
services pursuant to agreement providing for the right of said repurchase.

         3.     VOTING RIGHTS.

                (a)     Except as otherwise required by law or by Section 3(b)
hereof, the holder of each share of Common Stock issued and outstanding shall
have one vote and each holder of shares of Preferred shall be entitled to the
number of votes equal to the number of shares of Common Stock into which such
shares of Preferred could be converted at the record date for determination of
the stockholders entitled to vote on such matters, or, if no such record date is
established, at the date such vote is taken or any written consent of
stockholders is solicited, such votes to be counted together with all other
shares of stock of the Corporation having general voting power and not
separately as a class except as otherwise provided herein or by law. Fractional
votes by the holders of Preferred shall not, however, be permitted and any
fractional voting rights shall (after aggregating all shares into which shares
of the Preferred held by each holder could be converted) be rounded to the
nearest whole number. Holders of Common Stock and the Preferred shall be
entitled to notice of any stockholders' meeting in accordance with the Bylaws of
the Corporation.

                (b)     Notwithstanding Section 3(a) above, the Class B Common
shall not have any voting rights except as required by law.

                (c)     At each annual or special meeting called for the purpose
of electing directors, the holders of Series E Preferred, voting together as a
class, shall be entitled to elect one (1) director of the Corporation, the
holders of Series H Preferred, voting together as a class, shall be entitled to
elect one (1) director of the Corporation and the holders of Series K Preferred,
voting together as a class, shall be entitled to elect one (1) director of the
Corporation. Subject to the restrictions of Section 3(b) above, all remaining
directors shall be elected by the holders of the Common Stock and the Preferred
Stock (on an as-converted basis) voting together as a single class. In the case
of a vacancy in the office of director elected by the holders of (i) Series E
Preferred, (ii) Series H Preferred, or (iii) Series K Preferred, a successor
shall be elected to hold office for the unexpired term of such director by the
affirmative vote of the majority of the shares of such holders of (i) Series E
Preferred, (ii) Series H Preferred, or (iii) Series K Preferred, respectively.
In the case of any vacancies in the office of the remaining directors elected by
holders of the Common Stock and the Preferred Stock (on an as-converted basis),
voting together as a class, any successor shall be elected to hold office for
the unexpired term of such director by the affirmative vote of the majority of
the shares of such holders of Common and Preferred Stock. Subject to Section 303
of the California Corporations Code, any director who shall have been elected by
holders of (i) Series E Preferred, (ii) Series H Preferred, (iii) Series K
Preferred, or (iv) Common Stock and Preferred Stock, may be removed during the
aforesaid term of office, either for or without cause by, and only by, the
affirmative vote of the holders of a majority of (i) Series E Preferred, (ii)
Series H Preferred, (iii) Series K Preferred, or (iv) Common Stock and Preferred
Stock, respectively, given at a special meeting of the stockholders duly called
or by an action by written consent for that purpose, and any such vacancy
thereby created may be filled by the vote of the holders of a majority of (i)
Series E Preferred, (ii) Series H Preferred, (iii) Series K Preferred, or (iv)
Common Stock and Preferred Stock, respectively, at such meeting or in such
consent.

         4.     CONVERSION. The holders of the Preferred have conversion rights
as follows (the "Conversion Rights"):

                (a)     RIGHT TO CONVERT. Each share of Series A Preferred, 
Series B Preferred, Series C Preferred, Series D Preferred, Series E 
Preferred, Series F Preferred, Series G Preferred, Series H Preferred, Series 
J Preferred and Series K Preferred shall be convertible, at the option

                                       5.

<PAGE>

of the holder thereof, at any time after the date of issuance of such share 
at the office of the Corporation or any transfer agent for the Preferred, 
into such number of fully paid and nonassessable shares of Class A Common as 
is determined by dividing the Conversion Price for such series of Preferred 
(determined as hereinafter provided) in effect at the time of the conversion 
into the "Conversion Value" per share of such series of Preferred. The number 
of shares of Class A Common into which each series of Preferred is 
convertible is hereinafter referred to as the "Conversion Rate" for such 
series. The Conversion Price per share of (i) Series A Preferred shall be 
$0.25, (ii) Series B Preferred shall be $0.375, (iii) Series C Preferred 
shall be $0.60, (iv) Series D Preferred shall be $1.085, (v) Series E 
Preferred shall be $3.30, (vi) Series F Preferred shall be $5.555874, (vii) 
Series G Preferred shall be $6.15, (viii) Series H Preferred shall be $3.68, 
(ix) Series J Preferred shall be $14.03274, and (x) Series K Preferred shall 
be $9.50. The Conversion Value per share of (i) Series A Preferred shall be 
$0.25, (ii) Series B Preferred shall be $0.375, (iii) Series C Preferred 
shall be $0.60, (iv) Series D Preferred shall be $1.085, (v) Series E 
Preferred shall be $3.30, (vi) Series F Preferred shall be $6.15, (vii) 
Series G Preferred shall be $6.15, (viii) Series H Preferred shall be $3.68, 
(ix) Series J Preferred shall be $14.03274, and (x) Series K Preferred shall 
be $9.50. The Conversion Price for each series of Preferred shall be subject 
to adjustment as hereinafter provided.

                (b)     AUTOMATIC CONVERSION. Each share of Preferred (other
than the Series J Preferred) shall automatically be converted into shares of
Class A Common at the then effective Conversion Price upon either of (a) the
closing of a firm commitment underwritten public offering pursuant to an
effective registration statement under the Securities Act of 1933, as amended,
covering the offer and sale of Common Stock for the account of the Corporation
to the public (an "Initial Public Offering") at a price per share (prior to
deduction of underwriter commissions and offering expenses) of not less than
$5.00 per share (appropriately adjusted for any stock dividends, stock splits,
combinations, recapitalizations or similar events) and an aggregate offering
price to the public of not less than $25,000,000 (prior to deduction of
underwriter commissions and offering expenses), or (b) upon the vote or written
consent of the holders of at least a majority of the Series Preferred (other
than the Series J Preferred) voting together as a separate class and the vote or
written consent of the holders of at least a majority of the Series K Preferred
Stock, voting together as a separate class. Each share of Series J Preferred
shall automatically be converted into shares of Class A Common at the then
effective Conversion Price upon the closing of and Initial Public Offering at a
price per share (prior to deduction of underwriter commissions and offering
expenses) of not less than $7.36 per share (appropriately adjusted for any stock
dividends, stock splits, combinations, recapitalizations or similar events) and
an aggregate offering price to the public of not less than $10,000,000 (prior to
deduction of underwriter commissions and offering expenses).

                (c)     MECHANICS OF CONVERSION. No fractional shares of Common
Stock shall be issued upon conversion of shares of Preferred. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the then
effective Conversion Price. Before any holder of Preferred shall be entitled to
convert the same into full shares of Common Stock and to receive certificates
therefor, he shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Corporation or of any transfer agent for the
Preferred, and shall give written notice to the Corporation at such office that
he elects to convert the same; provided, however, that in the event of an
automatic conversion pursuant to Section 4(b), the outstanding shares of
Preferred shall be converted automatically without any further action by the
holders of such shares and whether or not the certificates representing such
shares are surrendered to the Corporation or its transfer agent, and provided
further that the Corporation shall not be obligated to issue certificates
evidencing the shares of Common Stock issuable upon such automatic conversion
unless the certificates evidencing such shares of Preferred are either delivered
to the Corporation or its transfer agent as provided above, or the holder
notifies the Corporation or its transfer agent that such certificates have been
lost, stolen or destroyed and executes an agreement reasonably satisfactory to
the Corporation to


                                       6.

<PAGE>

indemnify the Corporation from any loss incurred by it in connection with the
theft, loss or destruction of such certificates. The Corporation shall, as soon
as practicable after delivery of such certificates, or such agreement and
indemnification in the case of a lost certificate, issue and deliver at such
office to such holder of Preferred, a certificate or certificates for the number
of shares of Common Stock to which he shall be entitled as aforesaid and a check
payable to the holder in the amount of any cash amounts payable as the result of
a conversion into fractional shares of Common Stock. Such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Preferred to be converted, or in the case of
automatic conversion on the date of closing of the offering, and the person or
persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock on such date.

                (d)     ADJUSTMENTS TO CONVERSION PRICE FOR DILUTIVE ISSUES.

                        (i)     SPECIAL DEFINITIONS. For purposes of this
Section 4(d), the following definitions shall apply:

                                (1)     "OPTIONS" shall mean rights, options or
warrants to subscribe for, purchase or otherwise acquire either Common Stock or
Convertible Securities.

                                (2)     "ORIGINAL ISSUE DATE" shall mean June
11, 1996.

                                (3)     "CONVERTIBLE SECURITIES" shall mean any
evidences of indebtedness, shares (other than the Common Stock) or other
securities convertible into or exchangeable for Common Stock.

                                (4)     "ADDITIONAL SHARES OF COMMON STOCK"
shall mean all shares of Common Stock issued (or, pursuant to Section 4(d)(ii),
deemed to be issued) by the Corporation after the Original Issue Date, other
than shares of Common Stock issued or issuable at any time:

                                        (A)     upon conversion of the shares of
Preferred authorized herein;

                                        (B)     (i) to officers, directors, and
employees of, and consultants to, the Corporation to be designated pursuant to
plans and arrangements approved by the Board of Directors; and (ii) to lending
or leasing institutions approved by the Board of Directors, provided that the
aggregate of (i) and (ii) do not exceed more that 4,058,821 shares (net of
shares repurchased and Options expiring unexercised), appropriately adjusted for
stock splits, combinations, stock dividends, recapitalizations, or similar
events (provided that any shares repurchased by the Corporation from employees,
officers, directors and consultants pursuant to the terms of stock repurchase
agreements approved by the Board of Directors, or Options which terminate
unexercised, shall not, unless reissued, be counted as issued for purposes of
this calculation);

                                        (C)     as a dividend or distribution on
Preferred or any event for which adjustment is made pursuant to Section 4(e)
hereof;

                                        (D)     by way of dividend or other
distribution on shares of Common Stock excluded from the definition of
Additional Shares of Common Stock by the foregoing clauses (A), (B), or (C).

                                       7.

<PAGE>

                        (ii)    DEEMED ISSUE OF ADDITIONAL SHARES OF COMMON
STOCK. In the event the Corporation at any time or from time to time after the
Original Issue Date shall issue any Options or Convertible Securities or shall
fix a record date for the determination of holders of any class of securities
entitled to receive any such Options or Convertible Securities, then the maximum
number of shares (as set forth in the instrument relating thereto assuming the
satisfaction of any conditions to exercisability, including without limitation,
the passage of time and without regard to any provisions contained therein for a
subsequent adjustment of such number) of Common Stock issuable upon the exercise
of such Options or, in the case of Convertible Securities and Options therefor,
the conversion or exchange of such Convertible Securities, shall be deemed to be
Additional Shares of Common Stock issued as of the time of such issue or, in
case such a record date shall have been fixed, as of the close of business on
such record date, provided that Additional Shares of Common Stock shall not be
deemed to have been issued unless the consideration per share (determined
pursuant to Section 4(d)(iv) hereof) of such Additional Shares of Common Stock
would be less than the Conversion Price for such series in effect on the date of
and immediately prior to such issue, or such record date, as the case may be,
and provided further that in any such case in which Additional Shares of Common
Stock are deemed to be issued:

                                (1)     no further adjustment in the Conversion
Price shall be made upon the subsequent issue of Convertible Securities or
shares of Common Stock upon the exercise of such Options or conversion or
exchange of such Convertible Securities;

                                (2)     if such Options or Convertible
Securities by their terms provide, with the passage of time or otherwise, for
any increase or decrease in the consideration payable to the Corporation, or in
the number of shares of Common Stock issuable, upon the exercise, conversion or
exchange thereof, the Conversion Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon any such increase or decrease
becoming effective, be recomputed to reflect such increase or decrease insofar
as it affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                                (3)     upon the expiration of any such Options
or any rights of conversion or exchange under such Convertible Securities which
shall not have been exercised, the Conversion Price computed upon the original
issue thereof (or upon the occurrence of a record date with respect thereto),
and any subsequent adjustments based thereon, shall, upon such expiration, be
recomputed as if,

                                        (A)     in the case of Convertible
Securities or Options for Common Stock, the only Additional Shares of Common
Stock issued were shares of Common Stock, if any, actually issued upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities and the consideration received therefor was the consideration
actually received by the Corporation for the issue of all such Options, whether
or not exercised, plus the consideration actually received by the Corporation
upon such exercise, or for the issue of all such Convertible Securities which
were actually converted or exchanged, plus the additional consideration, if any,
actually received by the Corporation upon such conversion or exchange, and

                                        (B)     in the case of Options for
Convertible Securities, only the Convertible Securities, if any, actually issued
upon the exercise thereof were issued at the time of issue of such Options, and
the consideration received by the Corporation for the Additional Shares of
Common Stock deemed to have been then issued was the consideration actually
received by the Corporation for the issue of all such Options, whether or not
exercised, plus the consideration deemed to have been received by the
Corporation upon the issue of the Convertible Securities with respect to which
such Options were actually exercised;

                                       8.

<PAGE>

                                (4)     no readjustment pursuant to clause (2)
or (3) above shall have the effect of increasing the Conversion Price to an
amount which exceeds the lower of (i) the Conversion Price on the original
adjustment date, or (ii) the Conversion Price that would have resulted from any
issuance of Additional Shares of Common Stock between the original adjustment
date and such readjustment date; and

                                (5)     in the case of any Options which expire
by their terms not more than 90 days after the date of issue thereof, no
adjustment of the Conversion Price shall be made until the expiration or
exercise of all such Options.

                        (iii)   ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF
ADDITIONAL SHARES OF COMMON STOCK.

                                (1)     SERIES E PREFERRED, SERIES F 
PREFERRED, SERIES H PREFERRED, SERIES J PREFERRED AND SERIES K PREFERRED. In 
the event the Corporation shall issue Additional Shares of Common Stock 
(including Additional Shares of Common Stock deemed to be issued pursuant to 
Section 4(d)(ii)) after the Original Issue Date without consideration or for 
consideration per share less than the Conversion Price for (i) the Series E 
Preferred, (ii) the Series F Preferred, (iii) the Series H Preferred, (iv) 
the Series J Preferred, and/or (v) Series K Preferred in effect on the date 
of and immediately prior to such issue, then and in such event, the 
Conversion Price for the (i) Series E Preferred, (ii) Series F Preferred, 
(iii) Series H Preferred, (iv) Series J Preferred, and/or (v) Series K 
Preferred if the applicable consideration per share is less than the 
Conversion Price then in effect for such series of Series Preferred, shall be 
reduced, concurrently with such issue, to a price determined by multiplying 
such Conversion Price by a fraction, the numerator of which shall be the 
number of shares of Common Stock outstanding immediately prior to such issue 
(including all shares of Common Stock issuable upon conversion of the 
outstanding shares of Preferred and all shares of Common Stock reserved for 
future issuance by the Board of Directors of the Corporation) plus the number 
of shares of Common Stock which the aggregate consideration received by the 
Corporation for the total number of Additional Shares of Common Stock so 
issued would purchase at such Conversion Price; and the denominator of which 
shall be the number of shares of Common Stock outstanding immediately prior 
to such issue (including all shares of Common Stock issuable upon conversion 
of the outstanding shares of Preferred and all shares of Common Stock 
reserved for future issuance by the Board of Directors of the Corporation) 
plus the number of such Additional Shares of Common Stock so issued. In the 
event the Conversion Price for the Series K Preferred shall be adjusted as a 
result of this Section 4(d)(iii), the Minimum Price (as defined below) shall 
also be adjusted by the same fraction used to adjust the Conversion Price for 
the Series K Preferred.

                                (2)     SERIES G PREFERRED. In the event the
Corporation shall issue Additional Shares of Common Stock (including Additional
Shares of Common Stock deemed to be issued pursuant to Section 4(d)(ii)) after
the Original Issue Date and on or prior to September 30, 1995 (the "Trigger
Date"), without consideration or for consideration per share less than the
Conversion Price for the Series G Preferred in effect on the date of and
immediately prior to such issue, then and in such event, the Conversion Price
for the Series G Preferred shall be reduced, concurrently with such issue, to a
price equal to the amount of consideration received by the Corporation per share
in such issuance. In the event this Corporation shall issue Additional Shares of
Common Stock (including Additional Shares of Common Stock deemed to be issued
pursuant to Section 4(d)(ii)) after the Trigger Date without consideration or
for consideration per share less than the Conversion Price of the Series G
Preferred in effect on the date of and immediately prior to such issue, then in
such event, the Conversion Price of Series G Preferred shall be reduced,
concurrently with such issue, to a price determined by multiplying such
Conversion Price by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issue (including
all shares of Common Stock issuable upon 

                                      9.

conversion of the outstanding Preferred Stock and all shares of Common Stock
received for future issuance by the Board of Directors of the Corporation) plus
the number of shares of Common Stock which the aggregate consideration received
by the Corporation for the total number of Additional Shares of Common Stock so
issued would purchase at such Conversion Price; and the denominator of which
shall be the number of shares of Common Stock outstanding immediately prior to
such issue (including all shares of Common Stock issuable upon conversion of the
outstanding Preferred Stock and all shares of Common Stock reserved for future
issuance by the Board of Directors of the Corporation) plus the number of such
Additional Shares of Common Stock so issued.

                                (3)     SERIES J PREFERRED. In the event the
Corporation shall undertake an Initial Public Offering at certain per share
prices set forth below (appropriately adjusted for any stock dividends, stock
splits, combinations, recapitalizations or similar events), the Series J
Preferred will undergo a Conversion Price adjustment. If the price per share to
the public in the Initial Public Offering is equal to or less than $11.22 and
higher than $9.82, the Conversion Price will be adjusted to $12.38345 per share.
If the price per share to the public in the Initial Public Offering is equal to
or less than $9.82 and higher than $8.42, the Conversion Price will be adjusted
to $11.69611 per share. If the price per share to the public in the Initial
Public Offering is equal to or less than $8.42 and higher than $7.02, the
Conversion Price will be adjusted to $11.07622 per share. If the price per share
to the public in the Initial Public Offering is equal to or less than $7.02, the
Conversion Price will be adjusted to $10.52310 per share.

                                (4)     SERIES K PREFERRED. In the event of (i)
an Initial Public Offering, (ii) a liquidation, dissolution, or winding up of
the Corporation, either voluntary or involuntary or (iii) a Change of Control
(collectively, a "Liquidity Event"), during the time periods and at the per
share prices set forth below (appropriately adjusted for any stock dividends,
stock splits, combinations, recapitalizations or similar events), the Series K
Preferred will undergo a Conversion Price adjustment. If the price per share (on
an if-as-converted to Common Stock basis) in the Liquidity Event (the "Liquidity
Price") is less than $21.11 per share, and the Liquidity Event occurs prior to
the first anniversary of the first issuance date of the Series K Preferred (the
"Series K Issuance Date"), the Conversion Price for the Series K Preferred will
be adjusted to forty-five percent (45%) of the Liquidity Price. If the Liquidity
Price is less than $27.14 per share and the Liquidity Event occurs after the
first anniversary and prior to the second anniversary of the Series K Issuance
Date, the Conversion Price will be adjusted to thirty-five percent (35%) of the
Liquidity Price. If the Liquidity Price is less than $38.00 per share and the
Liquidity Event occurs after the second anniversary of the Series K Issuance
Date, the Conversion Price will be adjusted to twenty-five percent (25%) of the
Liquidity Price. Notwithstanding the foregoing, in no event shall the minimum
Conversion price per share of the Series K Preferred be adjusted below $5.00 per
share (appropriately adjusted under Section 4(d)(iii)(1) and for any stock
dividends, stock splits, combinations, recapitalizations or similar events) (the
"Minimum Price").

                        (iv)    DETERMINATION OF CONSIDERATION. For purposes of
this Section 4(d), the consideration received by the Corporation for the issue
of any Additional Shares of Common Stock shall be computed as follows:

                                (1)     CASH AND PROPERTY. Such consideration
shall:

                                      10.

<PAGE>

                                        (A)     insofar as it consists of cash,
be computed at the aggregate amount of cash received by the Corporation
excluding amounts paid or payable for accrued interest or accrued dividends;

                                        (B)     insofar as it consists of
property other than cash, be computed at the fair value thereof at the time of
such issue, as determined in good faith by the Board irrespective of any
accounting treatment; and

                                        (C)     in the event Additional Shares
of Common Stock are issued together with other shares or securities or other
assets of the Corporation for consideration which covers both, be the proportion
of such consideration so received, computed as provided in clauses (A) and (B)
above, as determined in good faith by the Board.

                                (2)     OPTIONS AND CONVERTIBLE SECURITIES. The
consideration per share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 4(d)(ii), relating
to Options and Convertible Securities, shall be determined by dividing

                                        (x)     the total amount, if any,
received or receivable by the Corporation as consideration for the issue of such
Options or Convertible Securities, plus the minimum aggregate amount of
additional consideration (as set forth in the instruments relating thereto,
without regard to any provision contained therein for a subsequent adjustment of
such consideration) payable to the Corporation upon the exercise of such Options
or the conversion or exchange of such Convertible Securities, or in the case of
Options for Convertible Securities, the exercise of such Options for Convertible
Securities and the conversion or exchange of such Convertible Securities by

                                        (y)     the maximum number of shares of
Common Stock (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such number)
issuable upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.

               (e)      ADJUSTMENTS TO CONVERSION PRICE.

                        (i)     ADJUSTMENTS FOR STOCK DIVIDENDS, SUBDIVISIONS, 
COMBINATIONS OR CONSOLIDATION OF COMMON STOCK. In the event the outstanding 
shares of Common Stock shall be, after the Original Issue Date, subdivided 
(by stock split or otherwise) into a greater number of shares of Common 
Stock, or the Corporation shall declare or pay any dividend on the Common 
Stock payable in Common Stock, the Conversion Price for each series then in 
effect shall, concurrently with the effectiveness of such subdivision or 
stock dividend, be proportionately decreased based on the ratio of (i) the 
number of shares of Common Stock outstanding immediately prior to such 
subdivision or stock dividend to (ii) the number of shares of Common Stock 
outstanding immediately after such subdivision or stock dividend. In the 
event the outstanding shares of Common Stock shall, after the Original Issue 
Date, be combined or consolidated, by reclassification or otherwise, into a 
lesser number of shares of Common Stock, the Conversion Price for each series 
then in effect shall, concurrently with the effectiveness of such combination 
or consolidation, be proportionately increased on the same basis as set forth 
above.

                        (ii)    ADJUSTMENTS FOR OTHER DISTRIBUTIONS. In the 
event the Corporation at any time or from time to time, after the Original 
Issue Date, makes, or fixes a record date for the determination of holders of 
Common Stock entitled to receive any distribution payable in securities of 
the Corporation other than shares of Common Stock and other than as otherwise 
adjusted in 

                                      11.

<PAGE>

this Section 4 or as otherwise provided in Section 2, then and in each such
event provision shall be made so that the holders of Preferred shall receive
upon conversion thereof, in addition to the number of shares of Common Stock
receivable thereupon, the amount of securities of the Corporation which they
would have received had their shares of Preferred been converted into Common
Stock on the date of such event and had they thereafter, during the period from
the date of such event to and including the date of conversion, retained such
securities receivable by them as aforesaid during such period, subject to all
other adjustments called for during such period under this Section 4 with
respect to the rights of the holders of the Preferred.

                        (iii)   ADJUSTMENTS FOR RECLASSIFICATION,
EXCHANGE AND SUBSTITUTION. If the Common Stock issuable upon conversion of
shares of Preferred shall, after the Original Issue Date, be changed into the
same or a different number of shares of any other class or classes of stock,
whether by capital reorganization, reclassification or otherwise (other than a
subdivision or combination of shares provided for above), the Conversion Price
then in effect shall, concurrently with the effectiveness of such reorganization
or reclassification, be proportionately adjusted such that the shares of
Preferred shall be convertible into, in lieu of the number of shares of Common
Stock which the holders would otherwise have been entitled to receive, a number
of shares of such other class or classes of stock equivalent to the number of
shares of Common Stock that would have been subject to receipt by the holders
upon conversion of the Preferred immediately before that change.

               (f)      NO IMPAIRMENT. Except as permitted by Section 6, the 
Corporation will not, by amendment of its Certificate of Incorporation or 
through any reorganization, transfer of assets, consolidation, merger, 
dissolution, issue or sale of securities or any other voluntary action, avoid 
or seek to avoid the observance or performance of any of the terms to be 
observed or performed hereunder by the Corporation but will at all times in 
good faith assist in the carrying out of all the provisions of this Section 4 
and in the taking of all such action as may be necessary or appropriate in 
order to protect the Conversion Rights of the holders of Preferred against 
impairment, including setting aside and reserving for future issuance upon 
conversion of the outstanding shares of Preferred the number of shares of 
Common Stock issuable upon such conversion.

               (g)     CERTIFICATE AS TO ADJUSTMENTS. Upon the
occurrence of each adjustment or readjustment of the Conversion Price for a
series of Preferred pursuant to this Section 4, the Corporation at its expense
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and furnish to each holder of such series of Preferred a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based. The Corporation
shall, upon the written request at any time of any holder of such series of
Preferred, furnish or cause to be furnished to such holder a like certificate
setting forth (i) such adjustments and readjustments, (ii) the Conversion Price
in effect at the time for such series, and (iii) the number of shares of Common
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of such series of Preferred.

               (h)     NOTICES OF RECORD DATE. In the event that the
Corporation shall propose at any time:

                       (i)      to declare any dividend or distribution
upon its Common Stock, whether in cash, property, stock or other securities,
whether or not a regular cash dividend and whether or not out of earnings or
earned surplus;

                       (ii)     to offer for subscription pro rata to the 
holders of any class or series of its stock any additional shares of stock of 
any class or series or any other similar rights;

                                      12.

<PAGE>

                       (iii)    to effect any reclassification or
recapitalization of its Common Stock outstanding which results in a change in
the Common Stock; or

                       (iv)     to merge or consolidate with or into any
other corporation, or sell, lease or convey all or substantially all its
property or business, or to liquidate, dissolve or wind up;

                       Then, in connection with each such event, the 
Corporation shall send to the holders of the Preferred:

                                (1)      at least 20 days' prior written 
notice of the date on which a record shall be taken for such dividend, 
distribution or subscription rights (and specifying the date on which the 
holders of Common Stock shall be entitled thereto) or for determining rights 
to vote on the matters referred to in (iii) and (iv) above; and

                                (2)      in the case of the matters referred 
to in (iii) and (iv) above, at least 20 days' prior written notice of the 
date when the same shall take place and specifying the date on which the 
holders of Common Stock shall be entitled to exchange their Common Stock for 
securities or other property deliverable upon the occurrence of such event or 
the record date for the determination of such holders if such record date is 
earlier.

         Each such written notice shall be delivered personally or given by
first class mail, postage prepaid, addressed to the holders of the Preferred at
the address for each such holder as shown on the books of the Corporation.

         5.     REDEMPTION OF SERIES J PREFERRED.

                (a)     At the option of the holder thereof to be exercised not
less than sixty (60) days prior to the date of first redemption, the Corporation
shall redeem, from any source of funds legally available therefor, the Series J
Preferred in ten equal quarterly installments beginning not earlier than
December 31, 1998, and continuing thereafter on the same day of the month, on a
quarterly basis, (each a "Series J Redemption Date") until the remaining Series
J Preferred outstanding shall be redeemed. The Corporation shall effect such
redemptions on the applicable Series J Preferred Redemption by paying in cash in
exchange for the shares of Series J Preferred to be redeemed a sum equal to
$14.03274 per share of Series J Preferred (as adjusted for any stock dividends,
combinations or splits or other adjustments pursuant to Section 4 with respect
to such shares) plus all declared but unpaid dividends on such shares (the
"Series J Redemption Price").

                (b)     The Corporation shall also pay interest on the
outstanding balance due with respect to the Series J Redemption Price, to begin
accruing on the first Series J Redemption Date, at 9 1/2% per annum and to be
payable with each subsequent installment ("Series J Interest Payment"). The
Series J Interest Payment for each quarter shall be calculated as the number of
Series J Preferred then outstanding times the Series J Redemption Price times
1/4 times .095.

                (c)     At least 10 but not more than 20 days prior to each
Series J Redemption Date written notice shall be mailed, first class postage
prepaid, to the holder of record (at the close of business on the business day
next preceding the day on which notice is given) of the Series J Preferred to be
redeemed, at the address last shown on the records of the Corporation for such
holder, notifying such holder of the redemption to be effected, specifying the
number of shares to be redeemed from such holder, the Series J Redemption Date,
the Series J Redemption Price, the place at which payment may be obtained and
calling upon such holder to surrender to the Corporation, in the manner and at
the place designated, his certificate or certificates representing the shares to
be redeemed (the "Redemption

                                      13.

<PAGE>

Notice"). On or after the Redemption Date, such holder shall surrender to the
Corporation the certificate or certificates representing such shares, in the
manner and at the place designated in the Redemption Notice, and thereupon the
Series J Redemption Price of such shares shall be payable to the order of the
person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be canceled. In the event less
than all the shares represented by any such certificate are redeemed, a new
certificate shall promptly be issued representing the unredeemed shares.

                (d)     From and after the Series J Redemption Date, unless
there shall have been a default in payment of the Redemption Price, all rights
of the holder of shares of Series J Preferred designated for redemption in the
Redemption Notice as holder of Series J Preferred shall cease with respect to
such shares, and such shares shall not thereafter be transferred on the books of
the Corporation or be deemed to be outstanding for any purpose whatsoever. If
the funds of the Corporation legally available for redemption of shares of
Series J Preferred on any Redemption Date are insufficient to redeem the total
number of shares of Series J Preferred to be redeemed on such date and pay the
Series J Redemption Price, those funds which are legally available will be used
to redeem the maximum possible number of such shares to be redeemed. The shares
of Series J Preferred not redeemed shall remain outstanding and shall be
entitled to all the rights and preferences provided herein. The Series J
Redemption Prices to the extent not paid when due shall accrue interest in
accordance with the terms hereof every quarter until paid. At any time
thereafter when additional funds of the Corporation are legally available for
the redemption of shares of Series J Preferred such funds will immediately be
used to redeem the balance of the shares which the Corporation has become
obliged to redeem on any Redemption Date, but which it has not redeemed, and pay
any amounts owed for Series J Redemption Prices and Interest Payments.

                (e)     On or prior to each Redemption Date, the Corporation
shall deposit the Series J Preferred Redemption Price of all shares of Series J
Preferred designated for redemption in the Redemption Notice and not yet
redeemed plus the Series J Interest Payment due with respect thereto or so much
thereof as is then legally available in accordance with Section 5(d), with a
bank or trust corporation having aggregate capital and surplus in excess of
$100,000,000 as a trust fund for the benefit of the holder of the shares
designated for redemption and not yet redeemed, with irrevocable instructions
and authority to the bank or trust corporation to pay the Series J Redemption
Price for such shares to their respective holders on or after the Redemption
Date upon receipt of notification from the Corporation that such holder has
surrendered his share certificate to the Corporation pursuant to Section (c)
above. For each Series J Redemption Date, unless otherwise provided in Section
5(d) above, the deposit shall constitute full payment of the shares to their
holders, and from and after Series J Redemption Date the shares so called for
redemption shall be redeemed and shall be deemed to be no longer outstanding,
and the holder thereof shall cease to be stockholder with respect thereto except
the rights to receive from the bank or trust corporation payment of the Series J
Redemption Price of the shares, without interest, upon surrender of their
certificates therefor. Such instructions shall also provide that any moneys
deposited by the Corporation pursuant to this Section 5(e) for the redemption of
shares thereafter converted into shares of the Corporation's Common Stock hereof
prior to the Redemption Date shall be returned to the Corporation forthwith upon
such conversion. The balance of any moneys deposited by the Corporation pursuant
to this Section 5(e) remaining unclaimed at the expiration of two (2) years
following each Series J Redemption Date shall thereafter be returned to the
Corporation upon its request expressed in a resolution of its Board of
Directors.

         6.     COVENANTS. In addition to any other rights provided by law, so
long as any shares of Preferred shall be outstanding, the Corporation shall not,
without first obtaining the affirmative vote or written consent of the holders
of not less than a majority of the outstanding shares of a series of Preferred:

                                      14.

<PAGE>

                (a)     amend or repeal any provision of, or add any 
provision to, the Corporation's Certificate of Incorporation if such action 
would materially and adversely directly alter or change the preferences, 
rights, or privileges of such series of Preferred;

                (b)     increase or decrease the authorized number of shares of
such series of Preferred;

                (c)     authorize, issue, or enter into any agreement providing
for the issuance of any capital stock or other equity security which is senior
to such series of Preferred with respect to the payment of dividends,
redemption, or distribution upon liquidation; or

                (d)     redeem, purchase, or otherwise acquire any of the 
Corporation's capital stock or other equity securities other than (i) shares 
of Common Stock repurchased at cost from terminated employees or consultants 
pursuant to contractual arrangements, or (ii) shares of Preferred redeemed 
pursuant to the terms of the Certificate of Incorporation of the Corporation.

         In addition to any other rights provided by law, so long as any shares
of Preferred shall be outstanding, the Corporation shall not, without first
obtaining the affirmative vote or written consent of the holders of a majority
of the outstanding shares of Preferred, voting together as a single class
(including the Series J Preferred):

                        (a)     sell or convey all or substantially all of its
property or business or merge into or consolidate with any other corporation if
immediately after such merger or consolidation the stockholders of the
Corporation shall hold less than 50% of the voting power of the surviving
corporation; or

                         (b)    liquidate, dissolve, or effect a
recapitalization or reorganization of the Corporation.

                                       VI.

                  For the management of the business and for the conduct of the
affairs of the corporation, and in further definition, limitation and regulation
of the powers of the corporation, of its directors and of its stockholders or
any class thereof, as the case may be, it is further provided that:

A.

         1.     The management of the business and the conduct of the affairs 
of the corporation shall be vested in its Board of Directors. The number of 
directors which shall constitute the whole Board of Directors shall be fixed 
exclusively by one or more resolutions adopted by the Board of Directors.

                                      15.

<PAGE>




         2.     BOARD OF DIRECTORS

                a.      Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances,
following the closing of the initial public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the "1933
Act"), covering the offer and sale of Common Stock to the public (the "Initial
Public Offering"), the directors shall be divided into three classes designated
as Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the closing
of the Initial Public Offering, the term of office of the Class I directors
shall expire and Class I directors shall be elected for a full term of three
years. At the second annual meeting of stockholders following the Initial Public
Offering, the term of office of the Class II directors shall expire and Class II
directors shall be elected for a full term of three years. At the third annual
meeting of stockholders following the Initial Public Offering, the term of
office of the Class III directors shall expire and Class III directors shall be
elected for a full term of three years. At each succeeding annual meeting of
stockholders, directors shall be elected for a full term of three years to
succeed the directors of the class whose terms expire at such annual meeting.
During such time or times that the corporation is subject to Section 2115(b) of
the California General Corporation Law ("CGCL"), this Section A.2.a of this
Article VI shall become effective and be applicable only when the corporation is
a "listed" corporation within the meaning of Section 301.5 of the CGCL.

                b.      In the event that the corporation is unable to have a
classified board under applicable law, Section 301.5 of the CGCL, Section A. 2.
a. of this Article VI shall not apply and all directors shall be elected at each
annual meeting of stockholders to hold office until the next annual meeting.

                c.      No stockholder entitled to vote at an election for 
directors may cumulate votes to which such stockholder is entitled, unless, 
at the time of such election, the corporation (i) is subject to Section 
2115(b) of the CGCL and (ii) is not or ceases to be a "listed" corporation 
under Section 301.5 of the CGCL. During this time, every stockholder entitled 
to vote at an election for directors may cumulate such stockholder's votes 
and give one candidate a number of votes equal to the number of directors to 
be elected multiplied by the number of votes to which such stockholder's 
shares are otherwise entitled, or distribute the stockholder's votes on the 
same principle among as many candidates as such stockholder thinks fit. No 
stockholder, however, shall be entitled to so cumulate such stockholder's 
votes unless (i) the names of such candidate or candidates have been placed 
in nomination prior to the voting and (ii) the stockholder has given notice 
at the meeting, prior to the voting, of such stockholder's intention to 
cumulate such stockholder's votes. If any stockholder has given proper notice 
to cumulate votes, all stockholders may cumulate their votes for any 
candidates who have been properly placed in nomination. Under cumulative 
voting, the candidates receiving the highest number of votes, up to the 
number of directors to be elected, are elected.

         Notwithstanding the foregoing provisions of this section, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.


                                      16.

<PAGE>




          3.    REMOVAL OF DIRECTORS

                a.      During such time or times that the corporation is
subject to Section 2115(b) of the CGCL, the Board of Directors or any individual
director may be removed from office at any time without cause by the affirmative
vote of the holders of at least a majority of the outstanding shares entitled to
vote on such removal; provided, however, that unless the entire Board is
removed, no individual director may be removed when the votes cast against such
director's removal, or not consenting in writing to such removal, would be
sufficient to elect that director if voted cumulatively at an election which the
same total number of votes were cast (or, if such action is taken by written
consent, all shares entitled to vote were voted) and the entire number of
directors authorized at the time of such director's most recent election were
then being elected.

                b.      At any time or times that the corporation is not subject
to Section 2115(b) of the CGCL and subject to any limitations imposed by law,
Section A. 3. a. above shall no longer apply and removal shall be as provided in
Section 141(k) of the DGCL.

         4.     VACANCIES

                a.      Subject to the rights of the holders of any series of
Preferred Stock, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors, shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by the stockholders, except as
otherwise provided by law, be filled only by the affirmative vote of a majority
of the directors then in office, even though less than a quorum of the Board of
Directors, and not by the stockholders. Any director elected in accordance with
the preceding sentence shall hold office for the remainder of the full term of
the director for which the vacancy was created or occurred and until such
director's successor shall have been elected and qualified.

                b.      If at the time of filling any vacancy or any newly
created directorship, the directors then in office shall constitute less than a
majority of the whole board (as constituted immediately prior to any such
increase), the Delaware Court of Chancery may, upon application of any
stockholder or stockholders holding at least ten percent (10%) of the total
number of the shares at the time outstanding having the right to vote for such
directors, summarily order an election to be held to fill any such vacancies or
newly created directorships, or to replace the directors chosen by the directors
then in offices as aforesaid, which election shall be governed by Section 211 of
the DGCL.

                c.      At any time or times that the corporation is subject to
Section 2115(b) of the CGCL, if, after the filling of any vacancy by the
directors then in office who have been elected by stockholders shall constitute
less than a majority of the directors then in office, then

                        (i)     Any holder or holders of an aggregate of five
percent (5%) or more of the total number of shares at the time outstanding
having the right to vote for those directors may call a special meeting of
stockholders; or

                        (ii)    The Superior Court of the proper county shall,
upon application of such stockholder or stockholders, summarily order a special
meeting of stockholders, to be held to elect the entire board, all in accordance
with Section 305(c) of the CGCL. The term of office of any director shall
terminate upon that election of a successor.

                                      17.

<PAGE>

B.

         1.     Subject to paragraph (h) of Section 43 of the Bylaws, the Bylaws
may be altered or amended or new Bylaws adopted by the affirmative vote of at
least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of
the then-outstanding shares of the voting stock of the corporation entitled to
vote. The Board of Directors shall also have the power to adopt, amend, or
repeal Bylaws.

         2.     The directors of the corporation need not be elected by written
ballot unless the Bylaws so provide.

         3.     No action shall be taken by the stockholders of the corporation
except at an annual or special meeting of stockholders called in accordance with
the Bylaws or by written consent of stockholders in accordance with the Bylaws
prior to the closing of the Initial Public Offering, and following the closing
of the Initial Public Offering no action shall be taken by the stockholders by
written consent.

         4.     Advance notice of stockholder nominations for the election of
directors and of business to be brought by stockholders before any meeting of
the stockholders of the corporation shall be given in the manner provided in the
Bylaws of the corporation.

                                      VII.

     This Collaborative Solutions Provider Agreement ("Agreement") is entered
into as of July 10, 2001 (the "Effective Date") by and between Bergen Brunswig
Drug Company, a California corporation ("Bergen") and Omnicell.com, a California
corporation ("Omnicell").

                                    RECITALS

     WHEREAS, Omnicell is a provider of clinical infrastructure and workflow
automation solutions for the healthcare industry;

     WHEREAS, Bergen is a wholesale distributor of pharmaceutical products and
provider of other goods and services;

     WHEREAS, the parties hereto desire to enter into this Agreement for the
purpose of setting forth the terms and conditions whereby Omnicell and Bergen
shall collaborate to jointly market one another's products and services and to
leverage their respective strengths in supply automation and hospital pharmacy
to compete more effectively in the automation and drug distribution
marketplaces.

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the mutual
 covenants of the parties set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by the parties, the parties agree
as follows:

1. COLLABORATION ACTIVITIES.

     1.1 Omnicell is in the business of providing clinical infrastructure and
workflow automation solutions. Omnicell's offerings include: Omnicell pharmacy
system, Sure-Med pharmacy system, supply systems and combination systems.

          The Omnicell and Sure-Med pharmacy systems, together with all other
future and existing products, modifications, enhancements, revisions and
upgrades thereof shall be referred to as the "Omnicell Products".

     1.2 Omnicell and Bergen will use commercially reasonable efforts to
collaborate in identifying, targeting and providing business opportunities to
prospective and existing customer accounts, including exchanging customer lists
(each on a strictly confidential basis), mutually analyzing and prioritizing
sales opportunities and conducting no less than quarterly meetings to effect the
purposes of this Agreement.

distribution, and in some cases, e-commerce platforms (collectively, "Bundled

IS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 OF THE
SECURITIES ACT OF 1933, AS AMENDED. 

     1.4 Bergen and Omnicell each have certain software platforms currently
known as InterLinx(TM) COE and OmniBuyer(TM), respectively, as the same exist or
may be changed or replaced from time to time (collectively, the "Software
Platforms"), which the parties intend to utilize on a customer-by-customer basis
as part of a Bundled Offering pursuant to terms and conditions of a separately
negotiated written agreement.

     1.5 In the event either party receives from a customer or prospective
customer a request for proposal, whether formal or informal, verbal or written
(each, an "RFP") which contemplates a Bundled Offering, the party receiving the
RFP shall promptly notify in writing the other party and communicate the details
of the RFP to the other party. Such other party will have the absolute right of
first refusal to participate in responding to the RFP. If the other party does
not indicate within thirty (30) days of receipt of notice of the RFP its desire
to participate in responding to the RFP, such party will be deemed to have
waived its right to participate.

requested a Bundled Offering or the parties have identified a customer for which
a Bundled Offering will be initiated, each party commits to use its commercially
reasonable efforts and provide adequate resources to collaborate with the other
party in good faith to create a Bundled Offering that has greater value to the
customer or prospective customer than the sum of the respective individual
offerings of Omnicell and Bergen. In such circumstances, neither Omnicell nor
Bergen shall negotiate outside the Bundled Offering with the customer unless the
other consents prior to such separate negotiations.

     1.7 Subject to the goals set forth in Subsection 1.6 above, each party will
have sole discretion and control over the final price structure for its
respective products and services whether or not included within a Bundled
Offering. In all circumstances, any prospective customer shall be given the
option of selecting either party's individual offering for automation and drug
distribution, respectively.

     1.8 Any development will be limited to ensuring that both companies'
e-commerce products and Software Platforms interface effectively. Any
development or integration of the party's e-commerce and Software Platforms,
each subject to the mutual approval(s) of the parties, shall be by separate
written agreements and under such terms and conditions as agreed upon by the
Chief Information Officer or Chief Technology Officer, as applicable, of each
respective company. Development of any new products will be discussed and
mutually agreed upon individually and as requested by customers.

     1.9 The designated Marketing Executives of each company shall meet annually
to plan the scope of joint marketing activities and approve a joint marketing
budget for purposes of this Agreement and the amount of marketing dollars
Omnicell will make available to Bergen for additional marketing activities. In
addition, each party shall make available to the other at no charge a sufficient
number of brochures and other printed materials.

of action upon which such damages might be based, including but not limited to
negligence or other tort, contract, strict liability, breach of warranty, or
otherwise.

10. RELATIONSHIP OF PARTIES.

     This Agreement does not in any way create the relationship of joint
venture, partnership or principal and agent between Omnicell and Bergen. Each
party is an independent contractor, and as such, shall not act or represent
itself, directly or indirectly or by implication, as agent for the other or
assume or create any obligation on behalf of or in the name of the other, or
otherwise bind the other in any manner. Without limiting the generality of the

into binding agreements of any nature whatsoever on behalf of Omnicell, without
the prior consent of Omnicell.

     During the Term of this Agreement, Bergen shall not compete with Omnicell
by entering into the automation dispensing markets and Omnicell will not compete

affiliated company of that party is acquired by a competitor of the non-acquired
party, then in such event, the non-acquired party shall be entitled to terminate
this Agreement immediately and without penalty. For purposes of this Agreement,
an "affiliate" or an "affiliated company" means, with respect to a party, any
entity that, directly or indirectly, or through one or more intermediaries, owns
or controls, is owned or controlled by, or is under common ownership or common
control with, that party. Likewise, "control" means either owning, directly or
indirectly, at least 51% of the voting stock or interests of a party (on a
fully-diluted basis) or having the ability, directly or indirectly, to elect a
majority of the board of directors or other governing members of a party.

12. COMPLIANCE WITH LAWS.

     Each party shall perform its obligations in compliance with all laws,
regulations, ordinances and orders ("Laws") of any applicable governmental
entity having jurisdiction over such party. Neither party shall be obligated to
perform any of the obligations contemplated by this Agreement to the extent
that, in the opinion of legal counsel to such party, doing so would violate any
Laws.

     14.8 ASSIGNMENT. Neither party may assign this Agreement without the prior
written consent of the other party (such consent not to be unreasonably
withheld), except to an affiliated entity. For purposes of this Section, any
transfer, sale, merger or consolidation of a party, or the sale of a substantial
portion of such party's assets, whether by contract, agreement, operation of

or substantially all of the party's business, assets (including this Agreement),
stock, or control shall be deemed an assignment and require the prior written

                                   SCHEDULE B


         1. In the event Bergen acquires Omnicell shares of stock in the 
initial public offering or otherwise makes an "Investment" pursuant to 
paragraph 6 below, Omnicell, at such time, shall begin to pay to Bergen a 
commission of [*] derived from pharmacy automation products ("Commission") at

Omnicell under the following circumstances:

         (a)  where the account is not then currently a customer of Bergen (as
              primary drug distributor) nor Omnicell, and selects Omnicell
              Product and Bergen (as primary drug distributor) as a result of a
              joint RFP response or joint marketing presentation by Omnicell and
              Bergen where the collaborative relationship has been presented to
              the account;

              Omnicell is not an existing supplier of the Omnicell Product and

              where the collaborative relationship has been presented to the
              account;

         (c)  where the account is not then currently a Bergen customer (as
              primary drug distributor) but is then currently an Omnicell
              customer and expands its Omnicell Product implementation and
              selects Bergen as the primary drug distributor as a result of a
              joint RFP response of joint marketing presentation by Omnicell and
