                                  THE COMPANY
 
The Company is a biopharmaceutical company focused exclusively on the
application of molecular cardiology to the discovery, development and
commercialization of novel, small molecule drugs for the treatment of chronic
cardiovascular diseases. Molecular cardiology was developed, in part, by CVT
scientists and their academic collaborators and is based upon the application of
molecular biology and genetics to cardiovascular diseases. This discipline has
yielded new insights into the mechanisms underlying chronic cardiovascular
diseases and has enhanced the search for innovative cardiovascular drugs by
providing an increasing number of new molecular targets for drug discovery. To
date, CVT has discovered five compounds and completed the strategic in-license
of a sixth compound for treatment of chronic cardiovascular diseases.
 
Cardiovascular disease is the leading cause of death in the United States,
claiming more than 950,000 lives in 1993. The American Heart Association
projects the total cost of cardiovascular medications in the United States for
1996 at $11 billion.
 
   
Two of the Company's drug candidates, CVT-124 and ranolazine, are in clinical
trials. CVT-124, an adenosine A(1) receptor antagonist discovered by CVT, has
potential applications in the treatment of edema associated with congestive
heart failure ("CHF") and in the prevention and treatment of acute renal
failure. A Phase I/II study completed by the Company in the United States
indicated that CVT-124 is generally well tolerated and produces diuretic
activity in healthy volunteers. Approximately one-quarter of the 875,000
patients in the United States hospitalized with a primary diagnosis of CHF
exhibit resistance to current intravenous diuretic treatments. The Company
believes that these patients would represent the initial target market for
CVT-124 in this indication.
    
 
   
The Company's second compound in clinical trials, ranolazine, is a novel
compound for the treatment of angina. Ranolazine was licensed from Syntex,
(U.S.A.), Inc. ("Syntex"), an indirect subsidiary of Roche Holding Limited
("Roche"), in March 1996. Its novel metabolic mechanism of action was
discovered, in part, by cardiovascular researchers now at or associated with
CVT. In Phase I and Phase II clinical trials conducted by Syntex, an immediate
release formulation of ranolazine ("ranolazine IR") was administered to over
1,200 patients. These clinical trials have indicated that ranolazine IR improved
exercise tolerance in angina patients without adversely affecting heart rate or
decreasing blood pressure, a clinical profile absent from currently available
drugs. Based on these data, as well as Syntex pilot Phase II data from a
sustained release formulation of ranolazine ("ranolazine SR") for intermittent
claudication, the Company intends to commence further clinical trials of
ranolazine SR. The Company believes ranolazine could particularly benefit angina
patients who also suffer from CHF or remain symptomatic despite maximal doses of
currently available anti-anginal drugs. In the United States, approximately 6.7
million patients are currently diagnosed with angina. Based on published
studies, approximately one-third, or 2.2 million, are either diagnosed with both
angina and CHF or are resistant to currently available treatments. The Company
believes these patients would represent the initial target market for
ranolazine.
    
 
The four other compounds discovered by the Company are in preclinical studies.
CVT-313 is a selective inhibitor of the cell cycle enzyme, cyclin-dependent
kinase 2 ("CDK2"). The Company believes that CVT-313 may be
 
                                       4
<PAGE>
useful in a variety of cellular proliferative disorders, including the
prevention of restenosis, as an adjunct to arterial bypass grafting and as a
treatment for cardiomyopathy. CVT-634, an inhibitor of another cell cycle
regulating enzyme, is also being evaluated in animal models of chronic
cardiovascular disease. CVT-609 and CVT-429 are highly selective adenosine A(1)
receptor agonists which the Company believes may have potential activity in
treating certain common cardiac arrhythmias. The Company believes that compared
to current therapies, these compounds may offer an improved clinical profile for
immediate treatment of these arrhythmias including avoiding unwanted blood
pressure lowering effects.
 
In addition, the Company has discovered a novel inflammatory factor found in
human cardiovascular diseases, which it partnered to Bayer AG for continued
development.
 
                               BUSINESS STRATEGY
 
The Company's strategy is to become a leader in the development of novel,
cost-effective treatments for chronic cardiovascular diseases by leveraging its
expertise in molecular cardiology. The Company is developing products based on
small molecules designed to (i) utilize novel mechanisms of action, (ii) address
segments of the cardiovascular patient population which are either underserved
or not treatable by existing therapies, and (iii) offer the currently served
cardiovascular patient population the potential for improved efficacy with fewer
side effects than currently available drugs.
 
The Company believes that it can best utilize its internal resources by
concentrating its activities on discovery, preclinical evaluation and early
clinical phases of drug development. The Company intends to establish
partnerships with pharmaceutical companies for later stage clinical trials and
marketing and sales activities for its products. The Company believes that such
partnerships will enable the Company to more effectively and economically
develop and market its initial products.
 
                            DRUG DISCOVERY PLATFORM
 
CVT's drug discovery platform supports several programs, including those focused
on the adenosine A(1) receptor, the cell cycle and chronic inflammation in the
cardiovascular system. These programs have produced compounds currently in
clinical or preclinical development or outlicensed for use in third party drug
discovery programs. CVT's expertise in molecular cardiology and drug development
has been critical to the identification of these drug candidates.
 
The Company believes that its drug discovery platform allows it to efficiently
select novel, clinically relevant drug candidates that have a significant
probability of commercial potential. CVT first evaluates new targets with
respect to clinical relevance and suitability for small molecule inhibition. CVT
then utilizes a highly integrated, multidisciplinary approach to produce novel
small molecules as drug candidates for these targets. The Company combines
molecular modeling and combinatorial chemistry to assemble targeted libraries of
new chemical entities, an approach which the Company believes expedites the
identification of potential drug leads. The Company has developed a
comprehensive proprietary database correlating biological activity of candidate
drugs with their structures. From this database, CVT identifies final lead
compounds based on predetermined development criteria including potency,
specificity, manufacturability, and pharmacologic activity in animal and IN
VITRO models. The Company determines the proper selection of cell-based assays
and animal models of disease to enhance development of the drug candidate based
on its projected use in the clinical setting.

                                  RISK FACTORS
 
An investment in the shares of Common Stock offered hereby involves a high
degree of risk. Prospective investors should carefully consider, in addition to
the other information contained in this Prospectus, the following risk factors
in evaluating the Company and the Common Stock offered hereby.
 
UNCERTAINTIES RELATED TO EARLY STAGE OF DEVELOPMENT
 
   
The Company is a development stage company and must be evaluated in light of the
uncertainties and complications present in an early stage biopharmaceutical
company. In addition, all of the Company's products are at an early stage of
development. Since the Company's inception in 1990, substantially all of the
Company's resources have been dedicated to research and development, and the
Company has not generated any product revenue. Because all of the Company's
potential products are in research, preclinical or clinical development, product
revenues will not be realized for at least several years, if at all. Drug
discovery methods based upon molecular cardiology are relatively new, and there
can be no assurance that the Company will be able to employ these methods of
drug discovery successfully or that these methods will lead to the development
of commercially viable pharmaceutical products. Certain of the Company's
compounds within the Company's cell cycle, chronic inflammation and adenosine
A(1) receptor programs are in the early stages of research and development and
the Company does not expect to commence clinical trials for such new compounds
for several years. There can be no assurance that any of the Company's product
development efforts will be successfully completed, that any of the Company's
products will be proven to be safe and effective, that regulatory approvals will
be obtained at all or be as broad as sought, that the Company's products will be
capable of being produced in commercial quantities or that any products, if
introduced, will achieve market acceptance.
    
 
UNCERTAINTIES RELATED TO CLINICAL TRIALS
 
The Company's potential products are subject to the risks of failure inherent in
the development of pharmaceutical products. The Company currently has only two
products in clinical development, CVT-124 and ranolazine. The Company's product
candidates will require additional development, preclinical studies, clinical
trials and regulatory approval prior to commercialization. The results from
preclinical studies and early clinical trials may not be predictive of results
obtained in later clinical trials, and there can be no assurance that clinical
trials conducted by the Company will demonstrate sufficient safety and efficacy
to obtain the requisite approvals or that marketable products will result. For
example, in November 1995, based on unfavorable efficacy data from a Phase II
trial, the Company terminated its development program for the CVT-1 product for
treatment of primary hypercholesterolemia.
 
The rate of completion of the Company's clinical trials may be delayed by many
factors, including slower than anticipated patient enrollment, difficulty in
finding a sufficient number of patients fitting the appropriate trial profile or
in the acquisition of sufficient supplies of clinical trial materials or adverse
events occurring during the clinical trials. Completion of testing, studies and
trials may take several years, and the length of time varies substantially with
the type, complexity, novelty and intended use of the product. There can be no
assurance that the Company's drug discovery efforts will progress as expected or
that such efforts will lead to the discovery or development of any product. In
addition, data obtained from preclinical and clinical activities are susceptible
to varying interpretations, which could delay, limit or prevent regulatory
approval. Delays or rejections may be encountered based upon many factors,
including changes in regulatory policy during the period of product development.
No assurance can be given that any of the Company's development programs will be
successfully completed, that any investigational new drug ("IND") applications
will become effective or that additional clinical trials will be allowed by the
Food and Drug Administration ("FDA") or other regulatory authorities or that
clinical trials will commence as planned.
 
The Company's clinical development plan for ranolazine assumes that Phase I data
and data from several Phase II angina trials with ranolazine IR combined with
Phase I data and safety and tolerability data from a pilot Phase II trial for
intermittent claudication with ranolazine SR will be accepted by the FDA and
other regulatory authorities as a basis to initiate Phase III trials with
ranolazine SR. There can be no assurance that such clinical data will be
accepted by the FDA in support of initiation of such Phase III studies with
ranolazine SR for the treatment of angina or that the Company will not be
required or otherwise choose to conduct additional Phase II clinical trials of
ranolazine SR prior to commencement of Phase III clinical trials. As a result of
FDA reviews or
 
                                       7
<PAGE>
complications that may arise in any phase of the clinical trial program, there
can be no assurance that the proposed schedules for IND and clinical protocol
submissions to the FDA, initiations of studies and completions of clinical
trials can be maintained. Any delays in the Company's clinical trials would have
a material adverse effect on the Company's business, financial condition and
results of operations. See "Business - Government Regulation."
 
DEPENDENCE ON COLLABORATIVE AND LICENSING ARRANGEMENTS
 
The Company's strategy for the research, development and commercialization of
its product candidates has required, and will continue to require, the Company
to enter into various arrangements with corporate and academic collaborators,
licensors, licensees and others, and the Company will therefore be dependent
upon the success of these parties in performing their responsibilities. The
Company is currently seeking a corporate partner for ranolazine prior to
conducting Phase III studies for treatment of angina. The Company may also seek
a corporate partner for CVT-124. There can be no assurance that the Company will
be able to enter into collaborative arrangements or license agreements on
acceptable terms, or at all, or that any or all of the contemplated benefits
from such collaborative arrangements or license agreements will be realized.
Failure to obtain such arrangements or agreements would result in delays in the
development of the Company's proposed products or the inability to proceed with
the development, manufacture or sale of products, or the loss of third party
licenses or could require the Company to fund development internally. If the
Company were required to fund development internally, its future capital
requirements would increase substantially. There can be no assurance that the
Company could obtain additional funds to meet such increased capital
requirements on acceptable terms, or at all.
 
Certain of the collaborative arrangements that the Company may enter into in the
future may place responsibility on the collaborative partner for preclinical
testing and clinical trials, for manufacturing and for preparation and
submission of applications for regulatory approval of potential pharmaceutical
products. The Company cannot control the amount and timing of resources which
its collaborative partners devote to the Company's programs or potential
products. Should a collaborative partner fail to develop or commercialize
successfully any product candidate to which it has rights, the Company's
business may be materially and adversely affected. There can be no assurance
that collaborators will not pursue other technologies or product candidates
either on their own or in collaboration with others.
 
Collaborative arrangements may also require the Company to expend funds and to
meet certain milestones, and there can be no assurance that the Company will be
successful in doing so. The Company's agreement with the University of Florida
Research Foundation, Inc. in the area of adenosine receptors requires the
Company to reach certain preclinical and clinical milestones within defined time
periods to maintain exclusive rights under the license. The Company's agreement
with Syntex for ranolazine requires it to make certain payments based on the
time and progress of development activities. Failure of the Company to meet its
obligations under its collaborative arrangements could result in a termination
of those arrangements and the loss of rights to the compounds under development
and could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
There can be no assurance that disputes will not arise in the future with
respect to the ownership of rights to any technology developed with or by third
parties. These and other possible disagreements between collaborators and the
Company could lead to delays in the collaborative research, development or
commercialization of certain product candidates or could require or result in
litigation or arbitration, which would be time consuming and expensive, and
would have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business - Licenses and
Collaborations."
 
UNCERTAINTY OF FUTURE PROFITABILITY; ACCUMULATED DEFICIT
 
   
Since its inception, the Company has been engaged in research and development
activities and has generated no product revenues. As of September 30, 1996, the
Company had an accumulated deficit of approximately $43.6 million. The process
of developing the Company's products will require significant additional
research and development, preclinical testing and clinical trials, as well as
regulatory approval. These activities, together with the Company's general and
administrative expenses, are expected to result in operating losses for the
foreseeable future. The Company will not receive product revenues unless and
until it completes clinical trials with respect to
    
 
                                       8
<PAGE>
one or more products and successfully commercializes such products. There can be
no assurance that the Company will generate revenues or achieve and sustain
profitability in the future. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
NEED FOR ADDITIONAL FUTURE CAPITAL; UNCERTAINTY OF ADDITIONAL FUNDING
 
   
The Company will require substantial additional funding after this Offering in
order to complete its research and development activities and commercialize any
potential products. The Company has financed its operations primarily through
the sale of preferred equity securities, equipment and leasehold improvement
financing and other debt financing. The Company has generated no product
revenue, and none is expected for at least several years. The Company
anticipates that its existing resources, including the proceeds of this Offering
and projected interest income, will enable the Company to maintain its current
and planned operations through 1998. However, there can be no assurance that the
Company will not require additional funding prior to such time. If the Company
is unable to establish and maintain additional corporate partnerships for the
development of CVT-124 and ranolazine, the Company's future capital requirements
will increase substantially. In addition, the Company's future capital
requirements will depend on many other factors, including scientific progress in
its research and development programs, the size and complexity of such programs,
the scope and results of preclinical studies and clinical trials, the ability of
the Company to establish and maintain corporate partnerships, the time and costs
involved in obtaining regulatory approvals, the costs involved in filing,
prosecuting and enforcing patent claims, competing technological and market
developments, the cost of manufacturing preclinical and clinical material and
other factors not within the Company's control. There can be no assurance that
such additional financing to meet the Company's capital requirements will be
available on acceptable terms or at all. Insufficient funds may require the
Company to delay, scale back or eliminate some or all of its research or
development programs or to lose rights under existing licenses or to relinquish
greater or all rights to product candidates at an earlier stage of development
or on less favorable terms than the Company would otherwise seek or may
adversely affect the Company's ability to operate as a going concern. If
additional funds are raised by issuing equity securities, substantial dilution
to existing stockholders may result. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
    
 
UNCERTAINTY OF MARKET ACCEPTANCE
 
The Company's future profitability is dependent on commercial acceptance of its
potential products. The Company believes that market acceptance of its potential
products will depend on the Company's ability to provide acceptable evidence of
the safety, efficacy and cost-effectiveness of its products, as well as the
marketing strength of the Company's corporate partners. In addition, third party
payors can indirectly affect the demand for the Company's potential products by
regulating the maximum amount of reimbursement that will be provided. There can
be no assurance that potential products developed by the Company will achieve
market acceptance among patients, physicians or third party payors, even if
necessary regulatory and reimbursement approvals are obtained. Failure to
achieve market acceptance would have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business -
Marketing and Sales" and "- Government Regulation."
 
INTENSE COMPETITION
 
The pharmaceutical and biopharmaceutical industries are subject to intense
competition and significant, rapid technological change. If regulatory approvals
are received, certain of the Company's potential products will compete with well
established, FDA approved proprietary and generic therapies that have generated
substantial sales over a number of years and which are reimbursed from
government health administration authorities and private health insurers. In
addition, CVT is aware of companies which are developing products that will
compete for the same disease markets as its potential products. Many of the
Company's competitors and potential competitors have substantially greater
product development capabilities and financial, scientific, marketing and sales
resources than the Company. Other companies may succeed in developing products
earlier than the Company, obtaining approvals for such products from the FDA
more rapidly than the Company and its corporate partners, or developing products
that are safer or more effective than those under development or proposed to be
developed by the Company and its corporate partners. There can be no assurance
that research and development by others will not render the Company's technology
or its potential products obsolete or non-competitive. In
 
                                       9
<PAGE>
addition, there can be no assurance that the Company's competitors will not
develop more effective or more affordable products or achieve patent protection,
regulatory approval or product commercialization earlier than the Company. See
"Business - Competition."
 
UNCERTAINTY OF PATENT POSITION AND PROPRIETARY RIGHTS
 
   
The Company's success will depend to a significant degree on its ability to
obtain patents and licenses to patent rights, to maintain trade secrets and to
operate without infringing on the proprietary rights of others, both in the
United States and other countries. The Company has filed a number of United
States and foreign patent applications. In addition, in connection with its
corporate and academic collaborations, the Company has received licenses to a
number of issued patents and patent applications for CVT-124 and ranolazine. The
Company intends to continue to file applications as appropriate for patents
covering both its potential products and processes. There can be no assurance
that patents will issue from any of these applications, that any patent will
issue on technology arising from additional research or that patents that may
issue from such applications will be sufficient to protect the Company's
technology. Patent applications in the United States are maintained in secrecy
until a patent issues, and the Company cannot be certain that others have not
filed patent applications for technology covered by the Company's pending
applications or that the Company was the first to invent the technology that is
the subject of such patent applications. Competitors may have filed applications
for, or may have received patents and may obtain additional patents and
proprietary rights relating to, compounds, products or processes that block or
compete with those of the Company. If any of its competitors have filed patent
applications in the United States that claim technology also invented by the
Company, the Company may have to participate in interference proceedings
declared by the Patent and Trademark Office in order to determine priority of
invention and, thus, the right to a patent for the technology in the United
States, all of which could result in substantial cost to the Company. In
addition, litigation, which would result in substantial cost to the Company, may
be necessary to enforce any patents issued to the Company or to determine the
scope and validity of the proprietary rights of third parties. There can be no
assurance that any patents issued to the Company or to licensors from whom the
Company has licensed rights will not be challenged, invalidated or circumvented,
or that the rights granted thereunder will provide proprietary protection or
commercial advantage to the Company.
    
 
The commercial success of the Company will depend in part on the Company not
infringing patents issued to competitors and not breaching the licenses that
might cover technology used in the Company's potential products. Failure by the
Company to obtain a license to any technology required to commercialize its
potential products could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
The Company also relies on trade secrets to develop and maintain its competitive
position. Although the Company protects its proprietary technology in part by
confidentiality agreements with its employees, consultants, collaborators,
advisors and corporate partners, there can be no assurance that these agreements
will not be breached, that the Company will have adequate remedies for any
breach or that the Company's trade secrets will not otherwise become known or be
discovered independently by its competitors. See "Business - Patents and
Proprietary Technology."
 
DEPENDENCE ON KEY PERSONNEL; NEED TO ATTRACT AND RETAIN KEY EMPLOYEES AND
CONSULTANTS
 
The Company is highly dependent on certain members of its management and
scientific staff. In addition, the Company relies on consultants and advisors.
The loss of any of these persons could have a material adverse effect on the
Company's business, financial condition and results of operations. In order to
pursue its research and product development plans, the Company will be required
to attract and retain additional qualified scientific and other personnel. There
can be no assurance that the Company will be successful in attracting and
retaining these skilled persons who generally are in high demand by
pharmaceutical and biopharmaceutical companies and by universities and other
research institutions. The failure to successfully attract and retain qualified
personnel, consultants and advisors may impede the achievement of development
objectives and have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, a substantial
portion of the stock options currently held by many of the Company's key
employees are vested and may be fully vested over the next several years before
the Company achieves significant revenues or profitability. The Company intends
to grant additional options and provide other forms of incentive compensation to
attract and retain such key personnel. See "Business - Scientific Advisory
Board" and "Management."

LIMITED MANUFACTURING, MARKETING AND SALES EXPERIENCE
 
The Company has no experience in manufacturing, and currently lacks the
resources or capability to manufacture any of its potential products on a
clinical or commercial scale. The Company is currently, and will continue to be,
dependent on corporate partners, licensees or other third parties for the
manufacturing of clinical and commercial scale quantities of its products. There
can be no assurance that the Company will be able to maintain existing
agreements for manufacturing of clinical quantities of potential products, that
it will be able to enter into additional agreements with other third parties for
commercial scale manufacturing or that these parties will be able to develop
adequate manufacturing capabilities.
 
To date, the Company has no experience with sales, marketing or distribution.
The Company intends to rely on relationships with one or more pharmaceutical
companies with established distribution systems and direct sales forces to
market its products. In the event that the Company is unable to reach agreement
with one or more pharmaceutical companies to market its products, it may be
required to market its products directly and to develop a marketing and sales
force with technical expertise and with supporting distribution capability.
There can be no assurance that the Company will be able to establish in-house
sales and distribution capabilities or relationships with third parties, or that
it will be successful in commercializing any of its potential products. To the
extent that the Company enters into co-promotion or other licensing
arrangements, any revenues received by the Company will depend upon the efforts
of third parties, and there can be no assurance that such efforts will be
successful. See "Business - Marketing and Sales" and "- Manufacturing."
 
SIGNIFICANT GOVERNMENT REGULATION; NO ASSURANCE OF REGULATORY APPROVAL
 
The research, testing, manufacture and marketing of drug products is subject to
extensive regulation by numerous regulatory authorities in the United States and
other countries. Failure to comply with FDA or other applicable regulatory
requirements may subject a company to administrative or judicially imposed
sanctions such as civil penalties, criminal prosecution, injunctions, product
seizure or detention, product recalls, total or partial suspension of
production, and FDA refusal to approve pending new drug applications ("NDAs") or
supplements to approved NDAs. The Company has not received regulatory approval
in the United States or any foreign jurisdiction for the commercial sale of any
of its products. The process of obtaining FDA and other required regulatory
approvals, including foreign approvals, often takes many years and can vary
substantially based upon the type, complexity and novelty of the products
involved. Furthermore, such approval process is extremely expensive and
uncertain. There can be no assurance that the Company's potential products will
be approved for marketing by the FDA. Even if regulatory approval of a product
is granted, there can be no assurance that the Company will be able to obtain
the labeling claims necessary or desirable for the promotion of those products.
FDA requirements prohibit the marketing or promotion of a drug for unapproved
indications. Furthermore, regulatory marketing approval may entail ongoing
requirements for postmarketing studies. If regulatory approval is obtained, the
Company will be subject to ongoing FDA obligations and continued regulatory
review. In particular, the Company or its third party manufacturer will be
required to adhere to regulations setting forth current Good Manufacturing
Practices ("cGMPs"), which require that the Company manufacture its products and
maintain its records in a prescribed manner with respect to manufacturing,
testing and quality control activities. Further, the Company or its third party
manufacturer must pass a preapproval inspection of its manufacturing facilities
by the FDA before obtaining marketing approval. Failure to comply with
applicable regulatory requirements may result in penalties such as restrictions
on a product's marketing or withdrawal of the product from the market. In
addition, identification of certain side effects after a drug is on the market
or the occurrence of manufacturing problems could cause subsequent withdrawal of
approval, reformulation of the drug, additional preclinical testing or clinical
trials and changes in labeling of the product.
 
Prior to the submission of an NDA, drugs developed by the Company must undergo
rigorous preclinical and clinical testing, which may take several years and the
expenditure of substantial resources. Before commencing clinical trials in
humans, the Company must submit to the FDA and receive clearance of an IND.
There can be no assurance that submission of an IND for future clinical testing
of any products under development or other future products of the Company would
result in FDA permission to commence clinical trials or that the Company will be
able to obtain the necessary approvals for future clinical testing in any
foreign jurisdiction. Success in preclinical studies or early stage clinical
trials does not assure success in later stage clinical trials. Data obtained
from preclinical and clinical activities are susceptible to varying
interpretations which could delay, limit or
 
                                       11
<PAGE>
prevent regulatory approval. Further, there can be no assurance that if such
testing of products under development is completed, any such drug compounds will
be accepted for formal review by the FDA or any foreign regulatory body, or
approved by the FDA for marketing in the United States or by any such foreign
regulatory bodies for marketing in foreign jurisdictions. Future federal, state,
local or foreign legislation or administrative acts could also prevent or delay
regulatory approval of the Company's products. See "Business - Government
Regulation."
 
UNCERTAINTY OF PRODUCT PRICING AND REIMBURSEMENT
 
The ability of the Company and its potential corporate partners to market and
sell its potential products successfully will depend in part on the extent to
which reimbursement for the cost of such potential products and related
treatments will be available from government health administration authorities,
private health insurers and other organizations. Third party payors are
increasingly challenging the price of medical products and services. Significant
uncertainty exists as to the reimbursement status of newly-approved health care
products. In addition, for sales of the Company's products in Europe, the
Company will be required to seek reimbursement on a country-by-country basis. If
the Company or any potential corporate partners succeed in bringing any products
to market, there can be no assurance that these products will be considered cost
effective, that reimbursement will be available, or if available, that the
payors' reimbursement policies will not adversely affect the Company's or any
such potential corporate partner's ability to sell such products on a profitable
basis.
 
PRODUCT LIABILITY EXPOSURE; AVAILABILITY OF INSURANCE
 
The manufacture and sale of biopharmaceutical products involve an inherent risk
of product liability claims and associated adverse publicity. The Company
currently has only limited product liability insurance for clinical trials and
no commercial product liability insurance. There can be no assurance that it
will be able to maintain existing or obtain additional product liability
insurance on acceptable terms or with adequate coverage against potential
liabilities. Such insurance is expensive, difficult to obtain and may not be
available on acceptable terms, or at all. An inability to obtain sufficient
insurance coverage on reasonable terms or to otherwise protect against potential
product liability claims could prevent or inhibit the commercialization of the
Company's potential products. A successful product liability claim brought
against the Company in excess of its insurance coverage, if any, could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business - Product Liability Insurance."
 
HAZARDOUS AND RADIOACTIVE MATERIALS; ENVIRONMENTAL MATTERS
 
The Company's research and development processes involve the controlled use of
hazardous materials, chemicals and radioactive materials, and produce waste
products. The Company is subject to federal, state and local laws and
regulations governing the use, manufacture, storage, handling and disposal of
such materials and waste products. Although the Company believes that its safety
procedures for handling and disposing of such materials comply with the
standards prescribed by such laws and regulations, the risk of contamination or
injury from these materials cannot be eliminated completely. In such event, the
Company could be held liable for any damages that result and any such liability
could exceed the resources of the Company. Although the Company believes that it
is in compliance in all material respects with applicable environmental laws and
regulations, there can be no assurance that it will not be required to incur
significant costs to comply with environmental laws and regulations in the
future, or that the Company's business, financial condition or results of
operations will not be materially adversely affected by current or future
environmental laws or regulations. See "Business - Government Regulation."
 
ABSENCE OF PRIOR PUBLIC MARKET; VOLATILITY OF STOCK PRICE
 
Prior to this Offering, there has been no public market for the Common Stock,
and there can be no assurance that an active market will develop or be
maintained. The initial public offering price will be negotiated between the
Company and the representatives of the Underwriters and may not be indicative of
future market prices. See "Underwriting" for information related to the method
of determining the initial public offering price. The market price of the shares
of Common Stock, like that of the common stock of many other biopharmaceutical
companies, is likely to be highly volatile. Factors such as the Company's
operating results, developments in the Company's relationships with corporate
partners, developments affecting the Company's corporate partners, announcements
of results of preclinical studies and clinical trials by the Company, its
corporate partners or its competitors, negative
 
                                       12
<PAGE>
regulatory action or regulatory approval with respect to the Company or its
competitors, announcements of new products by the Company or its competitors,
developments related to patent or other proprietary rights by the Company or its
competitors, changes in the position of securities analysts with respect to the
Common Stock, and market conditions for biopharmaceutical or biotechnology
stocks in general, may cause the market price of the Common Stock to fluctuate,
perhaps substantially. In addition, in recent years the stock market in general,
and the shares of biopharmaceutical, biotechnology and healthcare companies in
particular, have experienced extreme price fluctuations. These broad market and
industry fluctuations may materially adversely affect the market price of the
Common Stock. In some future quarter the Company's operating results may be
below the expectations of public market analysts and investors, and, as a
result, the price of the Common Stock would likely be materially adversely
affected.
 
CONTROL BY EXISTING STOCKHOLDERS; ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER
PROVISIONS AND DELAWARE LAW
 
   
After this Offering, the Company's officers, directors and principal
stockholders will beneficially own approximately 17.95% of the outstanding
shares of Common Stock. As a result, such persons may have the ability to
effectively control the Company and direct its affairs and business. Such
concentration of ownership may also have the effect of delaying, deferring or
preventing a change in control of the Company. In addition, the Company's Board
of Directors will have the authority to issue up to 5,000,000 shares of
Preferred Stock and to determine the price, rights, preferences and privileges
of those shares without any further vote or action by the stockholders. The
rights of the holders of Common Stock will be subject to, and may be materially
adversely affected by, the rights of the holders of any Preferred Stock that may
be issued in the future. The issuance of Preferred Stock could have the effect
of making it more difficult for a third party to acquire a majority of the
outstanding voting stock of the Company. Furthermore, certain provisions of the
Company's Certificate of Incorporation may have the effect of delaying or
preventing changes in control or management of the Company, which could
adversely affect the market price of the Company's Common Stock. In addition,
the Company will be subject to the provisions of Section 203 of the Delaware
General Corporation Law (the "Delaware Law"), an anti-takeover law. See
"Principal Stockholders" and "Description of Capital Stock."
    
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
   
Sales of substantial shares of Common Stock in the public market after the
Offering could adversely affect the market price of the Common Stock. Upon
completion of the Offering, the Company will have outstanding 6,950,356 shares
of Common Stock. All of the 2,500,000 shares sold in the Offering will be freely
transferable as of the date of this Prospectus by persons other than
"affiliates" of the Company without restriction or further registration under
the Securities Act of 1933, as amended (the "Securities Act"). The remaining
4,450,356 shares of Common Stock that will be outstanding upon completion of the
Offering (the "Restricted Shares") will be held by officers, directors,
employees, consultants and other stockholders of the Company. The Restricted
Shares were sold by the Company in reliance upon exemptions from the
registration requirements of the Securities Act of 1933, as amended (the
"Securities Act") and are "restricted securities" under the Securities Act.
Certain holders of Restricted Shares have agreed not to sell their shares
without the prior written consent of J.P. Morgan Securities Inc. for a period of
180 days from the date of this Prospectus. Upon completion of the Offering,
approximately 92,785 shares will be eligible for sale in the public market
immediately following the Offering. Beginning 180 days after commencement of the
Offering, approximately 2,482,503 Restricted Shares that are subject to lock-up
agreements will become eligible for sale in the public markets subject to Rule
144 and Rule 701 under the Securities Act. The remaining approximately 1,875,068
Restricted Shares, which are also subject to such lock-up agreements, will
become eligible for sale under Rule 144 at various dates thereafter as the
holding period provisions of Rule 144 are satisfied. As of September 30, 1996,
803,338 shares were issuable upon exercise of currently outstanding options, all
of which are subject to the lock-up agreements described above. Of these shares,
317,093 will be vested 180 days after commencement of the Offering. As of
September 30, 1996, 574,504 shares were issuable upon exercise of currently
outstanding warrants, of which 490,004 shares are subject to the lock-up
agreements described above. Of these shares, 186,926 will become eligible for
sale in the public markets subject to Rule 144 beginning 180 days after
commencement of the Offering and 387,578 shares will become eligible for sale
subject to Rule 144 at various dates thereafter as the holding provisions of
Rule 144 are satisfied. In addition, 84,500 shares, which are not subject to
lock-up
    
 
                                       13
<PAGE>
   
agreements, will become eligible for sale in the public markets beginning after
September 15, 1997 pursuant to the terms of the individual warrants, subject to
Rule 144. Certain holders of shares of Common Stock and securities convertible
into or exercisable for shares of Common Stock have certain registration rights
under a registration rights agreement among such holders and the Company and
certain other agreements. In addition, following completion of the Offering, the
Company intends to register under the Securities Act approximately 1,415,666
shares of Common Stock subject to outstanding stock options or reserved for
issuance under the Company's Non-Employee Directors' Stock Option Plan, 1994
Equity Incentive Plan, 1992 Stock Option Plan and Employee Stock Purchase Plan
(the "Stock Plans") as well as stock options granted outside the Stock Plans.
See "Management - Director Compensation," "- Stock Plans," "Shares Eligible for
Future Sale" and "Description of Capital Stock - Registration Rights of Certain
Holders."
    
 
DILUTION; ABSENCE OF DIVIDENDS
 
   
The initial public offering price will be substantially higher than the book
value per share of Common Stock. Investors purchasing shares of Common Stock in
this Offering will therefore incur immediate, substantial dilution of $7.65 per
share in the net tangible book value of Common Stock. Additional dilution will
occur upon the exercise of outstanding options and warrants. See "Dilution." The
Company has never paid any cash dividends and does not anticipate paying cash
dividends in the foreseeable future. See "Dividend Policy."

<PAGE>
                                  THE COMPANY
 
The Company was incorporated in Delaware in December 1990 and changed its name
to CV Therapeutics, Inc. in June 1992. The Company's executive offices are
located at 3172 Porter Drive, Palo Alto, California 94304, and its telephone
number is (415) 812-0585.
 
                                USE OF PROCEEDS
 
   
The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be $29.3 million (approximately $33.8 million if
the over-allotment option is exercised in full) at an assumed initial public
offering price of $13.00 per share after deducting the estimated underwriting
discount and estimated offering expenses payable by the Company.
    
 
   
The Company anticipates using approximately $16.0 million of the net proceeds of
the Offering to fund research and development activities, including preclinical
testing, clinical trials in support of regulatory approvals and the payment of
development milestones. The Company currently intends to use approximately $2.0
million of the net proceeds of the Offering to repay a $2.0 million term loan
portion of a debt financing with entities associated with Hambrecht & Quist
Group. The $2.0 million term loan bears interest at the rate of 9% per year. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources." The balance of the net proceeds
of the Offering are expected to be used for working capital and general
corporate purposes. In addition, a portion of the net proceeds may be used for
the acquisition of complementary businesses, products or technologies. The
Company has no present understandings, commitments or agreements, nor is it
engaged in any negotiations, with respect to any acquisition. Pending
application of the net proceeds of the Offering as described above, the Company
intends to invest such proceeds in short-term, investment-grade,
interest-bearing financial instruments.
    
 
   
The Company anticipates that its existing resources, including the net proceeds
of the Offering and projected interest income will enable the Company to
maintain its current and planned operations through 1998. The Company's forecast
of the period of time through which its financial resources will be adequate to
support its operations is a forward-looking statement that involves risks and
uncertainties, and actual results could vary as a result of a number of factors,
including those described in "Risk Factors" and elsewhere in this Prospectus.
    
 
                                DIVIDEND POLICY
 
The Company has never declared or paid any cash dividends on its capital stock.
The Company currently intends to retain any future earnings to finance the
growth and development of its business and therefore does not anticipate paying
any cash dividends in the foreseeable future.

The following table sets forth as of September 30, 1996, (i) the pro forma
capitalization of the Company giving effect to the conversion of all outstanding
shares of Preferred Stock into Common Stock and the issuance of 794,088 shares
of Common Stock upon the net exercise of certain outstanding warrants upon the
closing of this Offering, and (ii) the pro forma capitalization as adjusted to
give effect to the receipt by the Company of the estimated net proceeds from the
sale of the shares of Common Stock offered hereby at an assumed initial public
offering price of $13.00 per share, after deducting the estimated underwriting
discount and estimated offering expenses payable by the Company, and the
repayment of the $2.0 Million Tranche:

                                    DILUTION
 
   
The pro forma net tangible book value of the Company as of September 30, 1996
was approximately $7,908,000, or $1.78 per share of Common Stock. Pro forma net
tangible book value per share is determined by dividing the net tangible book
value (tangible assets less total liabilities) of the Company by the number of
shares of Common Stock outstanding at that date, after giving effect to the
issuance of 794,088 shares of Common Stock upon the net exercise of certain
outstanding warrants upon closing of this Offering. Without taking into account
any other changes in the net tangible book value after September 30, 1996, other
than to give effect to the receipt by the Company of the estimated net proceeds
from the sale of the 2,500,000 shares of Common Stock offered by the Company
hereby at an assumed initial public offering price of $13.00 per share, the pro
forma net tangible book value of the Company as of September 30, 1996 would have
been $37,208,000, or $5.35 per share. This represents an immediate increase in
the pro forma net tangible book value of $3.57 per share to existing
stockholders and an immediate dilution of $7.65 per share to new investors. The
following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
This Management's Discussion and Analysis of Financial Condition and Results of
Operations and other parts of this Prospectus contain forward-looking statements
which involve risks and uncertainties. The Company's actual results may differ
materially from the results discussed in the forward-looking statements. Factors
that might cause such a difference include, but are not limited to, those
discussed in "Risk Factors."
 
OVERVIEW
 
   
CVT is a development stage biopharmaceutical company focused exclusively on the
application of molecular cardiology to the discovery, development and
commercialization of novel small molecule drugs for the treatment of chronic
cardiovascular disease. Since its inception in December 1990, substantially all
of the Company's resources have been dedicated to research and development. To
date, CVT has not generated any product revenue and does not expect to generate
any such revenues for at least several years. As of September 30, 1996, the
Company has an accumulated deficit of approximately $43.6 million. The Company
expects its sources of revenue, if any, for the next several years to consist of
payments under future corporate partnerships and interest income. The process of
developing the Company's products will require significant additional research
and development, preclinical testing and clinical trials, as well as regulatory
approval. These activities, together with the Company's general and
administrative expenses, are expected to result in operating losses for the
foreseeable future. The Company will not receive product revenue unless it
completes clinical trials and successfully commercializes one or more of its
products.
    
 
CVT is subject to risks common to biopharmaceutical companies, including risks
inherent in its research and development efforts and clinical trials, reliance
on collaborative partners, enforcement of patent and proprietary rights, the
need for future capital, potential competition and uncertainty of regulatory
approval. In order for a product to be commercialized, it will be necessary for
CVT and its collaborators to conduct preclinical tests and clinical trials,
demonstrate efficacy and safety of the Company's product candidates, obtain
regulatory clearances and enter into manufacturing, distribution and marketing
arrangements, as well as obtain market acceptance. There can be no assurance
that the Company will generate revenues or achieve and sustain profitability in
the future.
 
RESULTS OF OPERATIONS
 
   
NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995
    
 
   
REVENUES.  The Company recognized revenues of $250,000 for the nine months ended
September 30, 1996, compared to no revenues for the nine months ended September
30, 1995. The revenue in 1996 was attributed to a non-refundable, up-front fee
earned from a license agreement with the Company's corporate partner.
    
 
   
RESEARCH AND DEVELOPMENT EXPENSES.  The Company's research and development
expenses decreased to $5.8 million for the nine months ended September 30, 1996,
compared to $10.1 million for the nine months ended September 30, 1995. The
higher expenses in 1995 were largely due to higher development expenditures
associated with the CVT-1 hypercholesterolemia program, which was terminated in
late 1995 and for which minimal costs were incurred in 1996. In addition,
research and development expenses decreased in 1996 as a result of a decrease in
research personnel and related expenses resulting from a reduction in headcount
in November 1995, partially offset by a $750,000 license fee paid to a
collaborative partner in March 1996 in equity securities. Under a current
license agreement, the Company may be obligated to make milestone payments
totaling $3.0 million to the licensor in 1997 unless the Company elects to
terminate the agreement. In addition, the Company expects research and
development expenses to increase significantly over the next several years as
the Company expands research and product development efforts and amortizes
deferred compensation expense. See Note 8 of Notes to Consolidated Financial
Statements.
    
 
   
GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses were
$2.2 million for the nine months ended September 30, 1996 compared to $2.4
million for the nine months ended September 30, 1995.
    
 
                                       19
<PAGE>
The Company expects general and administrative expense to increase in the future
due to an increase in the level of the Company's activities, additional expenses
associated with being a public company and amortization of deferred compensation
expense. See Note 8 of Notes to Consolidated Financial Statements.
 
   
INTEREST EXPENSE, NET.  Interest expense, net increased to $597,000 for the nine
months ended September 30, 1996, compared to $288,000 for the nine months ended
September 30, 1995, as a result of higher loan balances and prepayment penalties
associated with a restructuring of the Company's debt, partially offset by
higher average cash balances. The Company expects that interest expense, net
will decrease as a result of lower debt costs associated with the Company's debt
restructuring and anticipated increases in interest income generated from the
proceeds of the Offering.
    
 
YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
RESEARCH AND DEVELOPMENT EXPENSES.  The Company's research and development
expenses increased to $12.9 million for the year ended December 31, 1995, from
$8.8 million for the year ended December 31, 1994, and $4.7 million for the year
ended December 31, 1993. Research and development expenses increased as a result
of higher development expenses primarily associated with the CVT-1 program which
was terminated in late 1995, along with higher expenses associated with the
hiring of additional personnel to support the Company's expanding research and
product development efforts.
 
GENERAL AND ADMINISTRATIVE EXPENSES.  The Company's general and administrative
expenses increased to $3.4 million for the year ended December 31, 1995, from
$2.8 million for the year ended December 31, 1994, and $947,000 for the year
ended December 31, 1993, primarily as a result of costs associated with the
increasing level of the Company's activities, including increased headcount and
related expenses.
 
   
INTEREST EXPENSE, NET.  Interest expense, net increased to $466,000 for the year
ended December 31, 1995, from interest (income), net of $(258,000) for the year
ended December 31, 1994, and interest (income), net of $(161,000) for the year
ended December 31, 1993. These changes relate primarily to increased debt
balances and decreased cash and investment balances.
    
 
   
The Company records and amortizes over the related vesting periods deferred
compensation representing the difference between the exercise price of options
granted and the deemed fair value of its Common Stock at the time of grant.
Options generally vest over four years. Deferred compensation of approximately
$2.3 million was recorded in the nine months ended September 30, 1996.
    
 
The Company has not generated significant taxable income to date. At December
31, 1995, the net operating losses available to offset future taxable income for
federal income tax purposes were approximately $32.0 million. Because the
Company has experienced ownership changes, future utilization of the
carryforwards may be limited in any one fiscal year pursuant to Internal Revenue
Code regulations. The carryforwards expire at various dates beginning in 2007
through 2010 if not utilized. As a result of the annual limitation, a portion of
these carryforwards may expire before becoming available to reduce the Company's
federal income tax liabilities.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
The Company has financed its operations since inception primarily through
private placements of preferred equity securities, equipment and leasehold
improvement financing and other debt financing. As of September 30, 1996, the
Company had received approximately $50.4 million in net proceeds from the sale
of equity securities, and approximately $8.9 million from equipment and
leasehold financings and term loans. On September 30, 1996, the Company
refinanced its existing debt obligations with a $5 million debt financing with
entities associated with Hambrecht & Quist Group. See Note 5 of Notes to
Consolidated Financial Statements.
    
 
   
Cash, cash equivalents and short-term investments at September 30, 1996 totalled
$10.5 million compared to $5.6 million at December 31, 1995. The increase in
1996 was due to receipt of the net proceeds from the sale of equity securities.
The Company's funds are currently invested in short-term, investment grade,
interest-bearing debt obligations.
    
 
   
Net cash used in operations for the nine months ended September 30, 1996 was
$6.2 million, compared to $10.6 million for the nine months ended September 30,
1995. The decrease in cash used in operations was primarily a result of a
decrease in development expenses and reduced headcount and related expenses. Net
cash used in
    
 
                                       20
<PAGE>
operations in 1995 was $14.3 million, compared to $10.3 million in 1994. Net
cash used in operations increased primarily due to the increase in development
expenses, most of which were related to clinical trials and other development
expenditures for the CVT-1 program.
 
   
Through September 30, 1996, the Company had invested approximately $6.1 million
in property and equipment, of which approximately $4.4 million was financed
through the Equipment and Leasehold Financings. Minimum payments made under the
equipment and leasehold financings and other debt financings were approximately
$1.6 million in the nine months ended September 30, 1996 and $581,000 in the
nine months ended September 30, 1995.
    
 
   
On September 27, 1996, the Company completed a refinancing of its existing debt
obligations with $5.0 million of debt financing from entities associated with
Hambrecht & Quist Group (the H&Q Debt Financings). The H&Q Debt Financings
consist of a $3.0 million term loan which bears interest at the rate of 9.0% per
annum, secured by all of the assets of the Company, and has a final maturity in
September 1999, and a $2.0 million term loan which bears interest at 9.0% per
annum due January 1, 1997. The Company has the option on or before December 31,
1996 to convert the $2.0 million term loan to an equipment lease which would
bear interest at the rate of 9.0% per annum and would have a final maturity in
September 1999. If the Company does not raise a minimum of $13.0 million in
gross proceeds through the sale of equity securities by March 1998, the Company
can elect to defer payments under either the term loan (or the lease) until
March 1998 and minimum subsequent payments would total $3.2 million in 1998 and
$1.8 million in 1999. Otherwise, maximum payments could total $2.0 million, $1.7
million, and $1.3 million in 1997, 1998 and 1999, respectively. The Company
intends to use $2.0 million of the net proceeds from the Offering to repay the
$2.0 million term loan due January 1997. See Note 5 of Notes to Consolidated
Financial Statements.
    
 
The Company will require substantial additional funding after this Offering in
order to complete its research and development activities and commercialize any
potential products. The Company currently estimates that its existing resources,
including the net proceeds from this Offering and projected interest income,
will enable the Company to maintain its current and planned operations through
1998. However, there can be no assurance that the Company will not require
additional funding prior to such time. The Company's forecast of the period of
time through which its financial resources will be adequate to support its
operations is a forward-looking statement that involves risks and uncertainties,
and actual results could vary as a result of a number of factors, including
those described in "Risk Factors" and elsewhere in this Prospectus. If the
Company is unable to establish corporate partnerships for development of CVT-124
and ranolazine, the Company's future capital requirements will increase
substantially. In addition, the Company's future capital requirements will
depend on many other factors, including scientific progress in its research and
development programs, the size and complexity of such programs, the scope and
results of preclinical studies and clinical trials, the ability of the Company
to establish and maintain corporate partnerships, the time and costs involved in
obtaining regulatory approvals, the costs involved in filing, prosecuting and
enforcing patent claims, competing technological and market developments, the
cost of manufacturing preclinical and clinical material and other factors not
within the Company's control. There can be no assurance that such additional
financing to meet the Company's capital requirements will be available on
acceptable terms or at all. Insufficient funds may require the Company to delay,
scale back or eliminate some or all of its research or development programs, to
lose rights under existing licenses or to relinquish greater or all rights to
product candidates at an earlier stage of development or on less favorable terms
than the Company would otherwise choose or may adversely affect the Company's
ability to operate as a going concern. If additional funds are raised by issuing
equity securities, substantial dilution to existing stockholders may result.

OVERVIEW
 
The Company is a biopharmaceutical company focused exclusively on the
application of molecular cardiology to the discovery, development and
commercialization of novel, small molecule drugs for the treatment of chronic
cardiovascular diseases. Molecular cardiology was developed, in part, by CVT
scientists and their academic collaborators and is based upon the application of
molecular biology and genetics to cardiovascular diseases. This discipline has
yielded new insights into the mechanisms underlying chronic cardiovascular
diseases and has enhanced the search for innovative cardiovascular drugs by
providing an increasing number of new molecular targets for drug discovery. To
date, CVT has discovered five compounds and completed the strategic in-license
of a sixth compound for treatment of chronic cardiovascular diseases.
 
   
Two of the Company's drug candidates, CVT-124 and ranolazine, are in clinical
trials. CVT-124, an adenosine A(1) receptor antagonist discovered by CVT, has
potential applications in the treatment of edema associated with congestive
heart failure ("CHF") and in the prevention and treatment of acute renal
failure. A Phase I/II study completed by the Company in the United States
indicated that CVT-124 is generally well tolerated and produces diuretic
activity in healthy volunteers. Approximately one-quarter of the 875,000
patients in the United States hospitalized with a primary diagnosis of CHF
exhibit resistance to current intravenous diuretic treatments. The Company
believes that these patients would represent the initial target market for
CVT-124 in this indication.
    
 
   
The Company's second compound in clinical trials, ranolazine, is a novel
compound for the treatment of angina. Ranolazine was licensed from Syntex in
March 1996. Its novel metabolic mechanism of action was discovered, in part, by
cardiovascular researchers now at or associated with CVT. In Phase I and Phase
II clinical trials conducted by Syntex, ranolazine IR was administered to over
1,200 patients. These clinical trials have indicated that ranolazine IR improved
exercise tolerance in angina patients without adversely affecting heart rate or
decreasing blood pressure, a clinical profile absent from currently available
drugs. Based on these data, as well as Syntex pilot Phase II data with
ranolazine SR for intermittent claudication, the Company intends to commence
further clinical trials of ranolazine SR. The Company believes ranolazine could
particularly benefit angina patients who also suffer from CHF or remain
symptomatic despite maximal doses of currently available anti-anginal drugs. In
the United States, approximately 6.7 million patients are currently diagnosed
with angina. Based on published studies, approximately one-third, or 2.2
million, are either diagnosed with both angina and CHF or are resistant to
currently available treatments. The Company believes these patients would
represent the initial target market for ranolazine.
    
 
Four other compounds discovered by the Company are in preclinical studies.
CVT-313 is a selective inhibitor of the cell cycle enzyme, cyclin-dependent
kinase 2 ("CDK2"). The Company believes that CVT-313 may be useful in a variety
of cellular proliferative disorders, including the prevention of restenosis, as
an adjunct to arterial bypass grafting and as a treatment for cardiomyopathy.
CVT-634, an inhibitor of another cell cycle regulating enzyme, is also being
evaluated in animal models of chronic cardiovascular disease. CVT-609 and
CVT-429 are highly selective adenosine A(1) receptor agonists which the Company
believes may have potential activity in treating certain common cardiac
arrhythmias. The Company believes that compared to current therapies, these
compounds may offer an improved clinical profile for immediate treatment of
these arrhythmias without unwanted blood pressure lowering effects.
 
In addition, the Company has discovered a novel inflammatory factor found in
human cardiovascular diseases, which it partnered to Bayer AG for continued
development.
 
BACKGROUND
 
The cardiovascular system is comprised of the heart, the blood vessels, the
kidneys and the lungs. Together, the components of the cardiovascular system
deliver oxygen and other nutrients to the tissues of the body and remove waste
products. The heart propels blood through a network of arteries and veins. The
kidneys closely regulate the blood volume and the balance of electrolytes (such
as sodium, potassium and chloride) in the blood, and the lungs oxygenate the
blood and remove carbon dioxide. To accomplish these tasks, the cardiovascular
system must maintain adequate blood flow, or cardiac output. Cardiac output is
determined by such factors as heart rate and blood pressure, which in turn are
controlled by a variety of hormones such as adrenaline, angiotensin and
 
                                       22
<PAGE>
adenosine. These hormones are small molecules which exert their effects by
binding to specific receptors on the surfaces of a variety of cell types in the
heart, lungs, blood vessels and kidneys. Any significant disruption of this
system results in cardiovascular disease.
 
Cardiovascular disease is the leading cause of death in the United States,
claiming more than 950,000 lives in 1993. The American Heart Association
projects the total cost of cardiovascular medications in the United States for
1996 at $11 billion.
 
   
Chronic cardiovascular diseases, including atherosclerosis (hardening of the
arteries), hypertension (high blood pressure) and others, may cause permanent
damage to the heart and blood vessels, leading to CHF, (4.7 million patients),
angina (6.8 million patients) and, heart attack (1.5 million patients). CHF
occurs when the heart becomes weakened and, as a result, can no longer maintain
adequate blood circulation throughout the body. The kidneys respond to this
decrease in blood flow by increasing the retention of salt and water, leading to
chronic symptoms such as shortness of breath and edema (fluid retention) in the
legs and lungs. Molecular cardiology has provided new insight into the
mechanisms underlying chronic cardiovascular diseases, thus creating the
opportunity for improved therapies.
    
 
   
Over the past twenty years, drugs such as nitrates, beta blockers, calcium
channel blockers and ACE inhibitors, have been developed to treat cardiovascular
diseases. These drugs have contributed to an increase in the survival of
patients who suffer from chronic cardiovascular disease; however, they also can
cause a variety of undesirable side effects, including fatigue, depression,
impotence, headaches, palpitations and edema.
    
 
BUSINESS STRATEGY
 
The Company's strategy is to become a leader in the development of novel,
cost-effective treatments for chronic cardiovascular diseases by leveraging its
expertise in molecular cardiology. The Company is developing products based on
small molecules designed to (i) utilize novel mechanisms of action, (ii) address
segments of the cardiovascular patient population which are either underserved
or not treatable by existing therapies, and (iii) offer the currently served
cardiovascular patient population the potential for improved efficacy with fewer
side effects than available drugs.
 
The Company believes that it can best utilize its internal resources by
concentrating its activities on discovery, preclinical evaluation and early
clinical phases of drug development. The Company intends to establish
partnerships with pharmaceutical companies for later stage clinical trials and
marketing and sales activities for its products. The Company believes that such
partnerships will enable it to more effectively and economically develop and
market its initial products.
 
DRUG DISCOVERY PLATFORM
 
CVT's drug discovery platform supports several programs, including those focused
on the adenosine A(1) receptor, the cell cycle and chronic inflammation in the
cardiovascular system. These programs have produced compounds currently in
clinical or preclinical development or outlicensed for use in third party drug
discovery programs. CVT's expertise in molecular cardiology and drug development
has been critical to the identification of these drug candidates.
 
   
The Company believes that its drug discovery platform allows it to efficiently
select novel, clinically relevant drug candidates that have a significant
probability of commercial potential. CVT first evaluates new targets with
respect to clinical relevance and suitability for small molecule inhibition. CVT
then utilizes a highly integrated, multidisciplinary approach to produce novel
small molecules as drug candidates for these targets. The Company combines
molecular modeling and combinatorial chemistry to assemble targeted libraries of
new chemical entities, an approach which the Company believes expedites the
identification of potential drug leads. The Company has developed a
comprehensive proprietary database correlating biological activity of candidate
drugs with their structures. From this database, CVT identifies final lead
compounds based on predetermined development criteria including potency,
specificity, manufacturability, and pharmacologic activity in animal and IN
VITRO models. The Company determines the proper selection of cell-based assays
and animal models of disease to enhance development of the drug candidate based
on its projected use in the clinical setting.

CVT-124
 
The Company believes that CVT-124 is the most potent and selective adenosine
A(1) receptor antagonist reported to date. Preclinical studies and clinical
trials have shown statistically significant increases in sodium excretion in
response to CVT-124. Thus, the Company believes that CVT-124 has the potential
to be an effective new therapy for treatment of edema due to CHF and prevention
and treatment of acute renal failure and is developing it for these uses.
 
CVT-124 was identified in the Company's adenosine A(1) receptor program. This
program is focused on the development of agents that are highly selective for
the adenosine A(1) receptor and has produced both antagonists and agonists to
this class of receptors. The Company continues to explore additional
applications of the technology developed in the adenosine A(1) receptor program.
 
Adenosine is a naturally occurring hormone that modulates different functions of
the heart, brain, kidney and blood vessels. Its actions are mediated in these
organs by two classes of receptors, A(1) and A(2), that stimulate very different
physiological effects that can be separately targeted in drug development.
Adenosine A(1) receptors are located on the proximal tubules of the kidney where
they stimulate reabsorption of sodium and hence of water. The Company believes
that it was among the first to identify the presence of these adenosine A(1)
receptors in the proximal tubule of the kidney. In contrast to A(1) receptors,
adenosine A(2) receptors stimulate the dilation of blood vessels in the heart,
muscles and kidney thereby lowering blood pressure.
 
CVT has focused on creating an adenosine A(1) receptor antagonist specific
enough to avoid blocking the A(2) receptor and thus avoiding unintended side
effects. This concept was developed based on the Company's insight into the
newly discovered role of the A(1) receptor on the proximal tubule cell of the
kidney and its potential importance in treatment of edema states, such as CHF,
which are characterized by excessive accumulation of sodium and water in the
body.
 
                                       24
<PAGE>
INDICATIONS
 
   
EDEMA ASSOCIATED WITH CONGESTIVE HEART FAILURE.  Approximately 4.7 million
people in the United States suffer from CHF, with an estimated 400,000 new
diagnoses each year. These patients typically seek medical help because of
edema, an accumulation of fluid in the lungs and extremities. Approximately
875,000 patients are hospitalized each year in the United States with a primary
diagnosis of CHF, and CHF is the leading cause of hospital admissions among
patients over 65. Approximately one-quarter of these hospitalized patients
exhibit resistance to current intravenous diuretic treatments. The Company
believes that these patients would represent the initial target market for
CVT-124 in this indication.
    
 
Edema fluid accumulates in the body because of adaptations by the kidney during
CHF. Each kidney is comprised of approximately one million tiny blood filtering
units called nephrons. (See Figure 1) Normally in each nephron, blood is
filtered at the renal glomerulus and sodium and water are reabsorbed by the
kidney at three locations further along the nephron. Fifty to seventy percent of
the filtered sodium is reabsorbed at the proximal tubule, the portion of the
nephron closest to the glomerulus. Up to 40% is reabsorbed at the loop of Henle,
and the remaining portion, usually less than 10%, is reabsorbed at the distal
tubule. The filtered, non-reabsorbed impurities wash out into the urine. In
patients suffering from CHF, blood flow through the kidney decreases because of
the poor pumping function of the heart. The kidney interprets this event as
blood loss and attempts to increase its retention of salt and water to maintain
blood pressure. It does this by shifting more (up to 99%) of its reabsorption of
sodium to the proximal tubule. The result is the harmful build-up of salt and
water in the body, leading to edema.
 
                                       25
<PAGE>
           Graphical description of sodium reabsorption in the kidney
 
   
 
Current treatment of CHF consists of therapy designed to improve the pumping
function of the heart combined with the administration of diuretics to eliminate
excess sodium and water from the body by blocking reabsorption in the kidney.
However, current diuretic therapies inhibit sodium reabsorption either at the
loop of Henle (furosemide) or the distal tubule (thiazides and spironolactone),
where as little as one percent of reabsorption of sodium can take place in
patients with advanced CHF. Since increasing amounts of sodium are reabsorbed
proximally as CHF worsens, distally acting drugs are correspondingly less
effective over time and patients become more symptomatic. Approximately one
quarter of hospitalized CHF patients exhibit resistance to current intravenous
diuretic therapies due to excessive fluid reabsorption in the proximal tubule,
and no therapy currently exists which targets this site of the disease process.
The dosage for the most commonly prescribed diuretics for edema associated with
CHF are often increased as the disease progresses, and therefore are
increasingly associated with toxic side effects, including potassium loss, which
may lead to an increased incidence of cardiac arrhythmias if potassium is not
monitored and replaced, and uric acid build-up which may lead to gout.
    
 
Preclinical studies conducted by the Company have indicated that CVT-124 acts as
a potent diuretic by blocking the adenosine A(1) receptors in the proximal
tubule that would ordinarily stimulate sodium reabsorption at that site. These
studies also indicated that CVT-124 acted at the distal tubule to reduce sodium
reabsorption and minimize potassium excretion. This combination of diuretic
mechanisms indicates a unique clinical profile as compared to currently
available drugs and suggests that CVT-124 may be particularly useful in the
treatment of edema associated with CHF on an acute and chronic basis.

<PAGE>
      Presentation of potential advantages of CVT over existing diuretics
 
   
 
CVT completed a double-blind, placebo-controlled Phase I/II trial of intravenous
CVT-124 in 26 healthy volunteers. Data from this trial support CVT-124's
combination of diuretic mechanisms. Statistically significant, dose-related
increases in sodium excretion were observed in response to CVT-124, amounting to
a doubling or more in the excretion of sodium compared to placebo. In contrast,
mean potassium excretion did not show clinically significant increases. Uric
acid excretion was also significantly increased by CVT-124 compared to placebo.
CVT-124 was generally well-tolerated.
    
 
   
ACUTE RENAL FAILURE.  Acute renal failure is a decline in kidney function that
may require temporary or chronic therapy with dialysis procedures. Acute renal
failure is a complication of certain general medical conditions associated with
low blood flow and certain commonly used medications or diagnostic agents, such
as cyclosporine, gentamicin, amphotericin, cisplatin, and radiocontrast dye used
in x-ray studies. Because the A(1) receptor may be relevant in this type of
kidney failure, CVT is planning clinical trials in acute renal failure to assess
the opportunity for its treatment and prevention by CVT-124.
    
 
FUTURE DEVELOPMENT OF CVT-124
 
   
While the Company's clinical trials to date have utilized an intravenous
formulation of CVT-124, the Company intends to develop CVT-124 in intravenous
and oral formulations, both for the treatment of edema in fluid-retaining states
like CHF and for the treatment or prevention of acute renal failure. There can
be no assurance that CVT-124 will prove to be safe or efficacious in humans or
that CVT-124 will obtain FDA or other regulatory or foreign marketing approval
for any indication.
    
 
The Company is currently planning three clinical trials: a Phase II intravenous
trial in stable CHF (18-24 patients); a Phase II intravenous trial in renal
transplant patients with acute renal failure (30-40 patients); and a Phase I
trial to explore the feasibility of an oral formulation (6-8 patients). The
first of these trials is planned to begin in the first half of 1997. The
Company's current estimate of the commencement of various clinical trials
included in this Prospectus are forward-looking statements that involve risks
and uncertainties. The actual clinical trial dates could differ materially from
those anticipated in these forward-looking statements as a result of certain
factors, including the Company's success in completing preclinical development
and the other factors set forth under "Risk Factors" and elsewhere in this
Prospectus.

RANOLAZINE
 
Ranolazine is a patented compound which has been tested by Syntex in Phase I and
Phase II trials in patients with angina. The compound fits the Company's
criteria for development candidates as it is a small molecule which works
through a novel mechanism of action. The Company successfully obtained a license
for ranolazine from Syntex in March 1996, after the acquisition of Syntex by
Roche. The Company is developing ranolazine to treat angina because the Company
believes it does not impair blood pressure or heart rate and has an improved
tolerability profile.
 
Ranolazine acts by modulating the body's metabolism to shift the source of
energy for the heart from fatty acid toward glucose. Ranolazine decreases the
heart's oxygen demand for a given level of cardiac work because less oxygen is
required to produce an equivalent amount of energy from glucose than from fatty
acids. The Company believes this effect on muscle metabolism may also benefit
patients suffering from intermittent claudication.
 
INDICATIONS
 
   
ANGINA.  Angina is a clinical syndrome manifested by chest pain caused by
myocardial ischemia (insufficient blood flow to the heart muscle) due to
blockage of the coronary arteries. Patients usually experience chest pain on
exertion which can become more severe over time. In the United States,
approximately 6.7 million patients are currently diagnosed with angina. Based on
a published multicenter study involving over 5,000 angina patients, over half of
these patients are currently being treated with multiple medications, including
nitrates, beta blockers and calcium channel blockers. These anti-anginal drugs
accounted for over $3.0 billion in U.S. sales in 1995. Based on published
studies, approximately one-third, or 2.2 million, of angina patients are either
diagnosed with both angina and CHF or are resistant to currently available
treatments. The Company believes these patients would represent the initial
target market for ranolazine.
    
 
All currently available drugs to treat angina reduce the heart's oxygen demand
by reducing cardiac work via hemodynamic mechanisms (reduction of pump function,
heart rate, and/or blood pressure). These hemodynamic effects can limit or
prevent the use of currently available drugs in patients whose blood pressure or
cardiac function is already decreased. These effects can be particularly
pronounced when these drugs are used in combination. Additional adverse effects
include lower extremity edema associated with calcium channel blockers,
impotence and depression associated with beta blockers and headaches associated
with nitrates. Consequently, for some patients, presently available medical
treatment cannot provide complete relief of angina without unacceptable adverse
effects. The following table sets forth the mechanisms through which
anti-anginal drugs operate:

Ranolazine IR has been administered to over 200 healthy human volunteers and
over 1,200 patients with ischemic heart disease or CHF in clinical trials
conducted by Syntex. Placebo controlled ranolazine IR trials
 
                                       28
<PAGE>
   
involving treadmill testing in patients with chronic stable angina have
demonstrated statistically significant and clinically meaningful increases in
(i) exercise time to onset of angina, (ii) total exercise duration, and (iii)
exercise time to onset of an electrocardiographic change associated with
insufficient blood flow to the heart muscle. The anti-anginal effect of
ranolazine IR was observed in these trials regardless of whether the drug was
given alone or in combination with beta blockers or calcium channel blockers,
and the drug was generally well tolerated without a significant incidence of
adverse events.
    
 
In initial clinical trials, ranolazine IR was administered on a three times
daily schedule. To achieve a more commercially attractive product with a
twice-daily dosing schedule, Syntex developed ranolazine SR. In volunteer trials
conducted by Syntex, the SR formulation maintained ranolazine plasma
concentrations in the range associated with increased exercise times in the
stable angina trials of ranolazine IR.
 
Although CVT intends to pursue regulatory approval for treatment of all patients
with chronic angina, the Company believes angina patients who are resistant to
currently available treatments and those with angina and CHF would represent the
initial market for ranolazine.
 
INTERMITTENT CLAUDICATION.  Intermittent claudication is a clinical syndrome
manifested by pain in the legs during exercise. Like angina, this syndrome is
caused by blockage or narrowing of arteries. These patients generally either
limit their activity or in severe cases undergo vascular surgery. Over two
million people in the United States suffer from intermittent claudication. Only
one drug is approved by the FDA to treat this condition in the United States,
and worldwide sales in 1995 were approximately $400 million.
 
A pilot trial of ranolazine SR in patients with intermittent claudication was
completed by Syntex in 1994. Ranolazine SR was generally well tolerated and
exhibited a trend toward prolongation of exercise duration and time to onset of
claudication. This clinical trial was not intended to be large enough to
demonstrate statistical significance. Further trials will be required to
demonstrate the utility of ranolazine SR for this indication.
 
DEVELOPMENT HISTORY OF RANOLAZINE
 
Following the acquisition of Syntex by Roche in 1994, ranolazine clinical
development was discontinued. Previously, Syntex had met with the FDA to
establish a Phase III clinical development program for ranolazine SR in both
angina and intermittent claudication and had begun enrollment in an angina Phase
III trial in late 1994.
 
FUTURE DEVELOPMENT OF RANOLAZINE
 
   
CVT is actively seeking a corporate partner for the development of ranolazine,
prior to initiating new Phase III trials in angina which the Company currently
expects to involve several hundred patients. The Company's clinical development
plan for ranolazine assumes that Phase I data and several Phase II angina trials
with ranolazine IR combined with Phase I data and safety and tolerability data
from a pilot Phase II trial for intermittent claudication with ranolazine SR
will be accepted by the FDA to initiate Phase III trials with ranolazine SR.
There can be no assurance that such clinical data will be accepted by the FDA in
support of initiation of such Phase III trials with ranolazine SR or that the
Company will not be required or otherwise choose to conduct additional Phase II
clinical trials of ranolazine SR prior to commencement of Phase III clinical
trials. Commencement of the Phase III trials by Syntex in 1994 was based upon
Phase I and II ranolazine IR data combined with Phase I ranolazine SR data. The
Company has initiated pharmacological and mechanism studies and is engaged in
the transfer of manufacturing technology from Syntex. There can be no assurance
that the Company will obtain a corporate partner to initiate Phase III trials,
that ranolazine will obtain FDA or other regulatory or foreign marketing
approval for any indication.
    
 
CVT-609 AND CVT-429
 
CVT-609 and CVT-429 were designed and synthesized in the Company's adenosine
A(1) receptor program. The Company believes that CVT-609 and CVT-429 may have
potential application in treating supraventricular tachycardia, as well as
additional applications. Based on preclinical data, the Company believes CVT-609
and CVT-429 are among the most selective adenosine A(1) receptor agonists
reported. Preclinical studies conducted by the Company indicated that CVT-609
and CVT-429 slowed electrical impulses in the conduction tissue of the heart by
stimulating the adenosine A(1) receptor.

Supraventricular tachycardias (atrial fibrillation, atrial flutter and AV nodal
re-entrant tachycardias) are among the most common cardiac arrhythmias
complicating ischemic heart disease and cardiac surgical procedures and account
for over 300,000 new hospital admissions in the United States each year. They
originate in the atria as rapid and irregular heart beats that then spread to
the ventricles. The ventricular contractions stimulated by the atrial impulses
can be so fast and irregular that cardiac function can be severely compromised,
resulting in dangerously low blood pressure, fluid in the lungs, and ischemic
damage to the heart, brain and other organs.
    
 
Because of the severity of these conditions and the need to treat patients
quickly, intravenous therapies are typically used. Current medical therapies aim
to slow the heart to a normal rate but have significant limitations in the acute
care setting. Digitalis is effective in controlling heart rate, but requires a
long time to take effect, which can be dangerous in patients with a failing
heart. Calcium channel blockers, beta blockers and adenosine act quickly but are
themselves associated with hypotension and depressed cardiac function,
potentially exacerbating the condition of patients already experiencing cardiac
dysfunction as a complication of the tachycardia.
 
For the treatment of supraventricular tachycardia, selective stimulation of the
A(1) receptor is required to slow the heart rate without significant stimulation
of the A(2) receptor which would lower blood pressure. The Company has
identified CVT-609 and CVT-429 as candidates for clinical development of
intravenous agents and is proceeding with preclinical studies.
 
CVT-313 AND CVT-634
 
   
CVT-313 and CVT-634 were designed and synthesized in the Company's cell cycle
inhibitor program. The goal of this program is to develop a new class of
therapeutics that suppresses abnormal cellular proliferation, which contributes
to progressive cardiovascular diseases. Excessive proliferation of
cardiovascular connective tissue cells or vascular smooth muscle cells causes
the scarring and loss of function that is characteristic of chronic diseases of
the heart, blood vessels and kidneys. Several of the Company's scientists and
scientific advisors have been among the leaders in identifying the role of cell
proliferation in causing a variety of cardiovascular diseases. As part of its
drug discovery strategy, the Company has focused upon newly discovered enzymes
referred to collectively as the cell cycle enzymes that regulate cellular
proliferation. In particular, two important targets identified by the Company,
CDK2 and the proteasomal protease, may have different clinical applications. The
Company is continuing to explore other cell cycle regulatory enzymes as
potential targets in this program.
    
 
CVT 313 is a novel compound which specifically inhibits CDK2, a critical
regulatory protein which participates in the control of the cell cycle. CDK2,
whose three dimensional structure was first determined by academic collaborators
of the Company, is central to cellular proliferation and was chosen as the
Company's first target in the cell cycle inhibitor program. Preclinical studies
have shown significant reduction of restenosis after vascular injury, both
confirming the appropriate selection of the target and identifying a potential
initial clinical application.
 
CVT-634, also identified in this program, has been shown to be a potent
inhibitor of proteasomal protease, which regulates both CDK2 activation and
macrophage activation. CVT-634 has been shown in preclinical studies to control
smooth muscle cell proliferation. This compound is undergoing further
preclinical testing.
 
CHRONIC ANTI-INFLAMMATORY INHIBITORS
 
CVT is seeking to address chronic inflammatory diseases of the cardiovascular
system by targeting macrophage infiltration into the heart and kidney. Activated
macrophages are a type of white blood cell found in lesions associated with
virtually all chronic cardiovascular diseases, including atherosclerotic plaque,
and are known to secrete growth factors which promote cellular proliferation and
scarring. The Company has discovered a novel inflammatory factor in this program
which has been partnered to Bayer AG for continued development.
 
LICENSES AND COLLABORATIONS
 
CVT has licensed certain chemical compounds from academic collaborators and
other companies and has applied its drug discovery strategies to analog and
optimize these structures and to identify applications for preclinical and
clinical development. Once these drug candidates enter clinical trials, the
Company intends to establish strategic partnerships to expedite development and
commercialization. For those programs which provide
 
                                       30
<PAGE>
knowledge useful in the identification of compounds with potential application
outside of chronic cardiovascular disease, the Company intends to find corporate
partners at the preclinical stage. The Company's licenses and collaborations
currently in effect include:
 
UNIVERSITY OF FLORIDA RESEARCH FOUNDATION
 
In June 1994, the Company entered into a license agreement with the University
of Florida Research Foundation, Inc. ("UFRFI") under which the Company received
exclusive worldwide rights to develop adenosine A(1) receptor antagonists and
agonists for the detection, prevention and treatment of human and animal
diseases. In consideration for the license, the Company paid UFRFI an initial
license fee and is obligated to pay royalties based on net sales of products
which utilize the licensed technology. Pursuant to the agreement, the Company
must exercise commercially reasonable efforts to develop and commercialize one
or more products covered by the licensed technology and is obligated to meet
milestones in completing certain preclinical work. In the event the Company
fails to reach those milestones, UFRFI may convert the exclusive license into a
non-exclusive license. As part of the license agreement with UFRFI, the Company
entered into a research agreement with the University of Florida.
 
SYNTEX/ROCHE
 
   
In March 1996, the Company entered into a license agreement with Syntex for
United States and foreign patent rights to a compound having the generic name of
ranolazine for products treating angina and certain other cardiovascular
indications. The agreement provides for Syntex to also supply certain quantities
of the compound to the Company. The license agreement is exclusive and worldwide
except for the following countries which Syntex licensed exclusively to Kissei
Pharmaceuticals, Ltd. of Japan: Japan, Korea, China, Taiwan, Hong Kong, the
Philippines, Indonesia, Singapore, Thailand, Malaysia, Vietnam, Myanmar, Laos,
Cambodia and Brunei. Under the license agreement, the Company paid an initial
license fee. In addition, the Company is obligated to make payments on the
achievement of certain development milestones and to make royalty payments based
on net sales of products which utilize the licensed technology. The Company is
required to use commercially reasonable efforts to develop the compound for
angina within certain milestone guidelines. The license agreement also sets
milestones within which the Company must launch products in each country covered
by the license or lose exclusivity in such territories.
    
 
BAYER AG
 
In May 1996, the Company granted an exclusive worldwide license to Bayer AG for
a novel inflammatory factor for preclinical and clinical development for any
therapeutic, prophylactic or diagnostic use in humans or animals. In
consideration of this license, Bayer AG paid the Company an initial fee and
agreed to make certain cash milestone payments related to the progress of
product development. Bayer AG is also obligated to pay the Company royalties
based on net sales of products which utilize the licensed technology. The
Company is responsible for the expenses of patent prosecution for the licensed
technology. Bayer AG may terminate the agreement for any reason upon written
notice to the Company.
 
MARKETING AND SALES
 
The Company currently has no sales, marketing or distribution capability. The
Company intends to rely on relationships with one or more pharmaceutical
companies with established distribution systems and direct sales forces to
market its products. In the event that the Company is unable to reach agreement
with one or more pharmaceutical companies to market its products, it may be
required to market its products directly and to develop a marketing and sales
force with technical expertise and with supporting distribution capability.
There can be no assurance that the Company will be able to establish in-house
sales and distribution capabilities or relationships with third parties, or that
it will be successful in commercializing any of its potential products. To the
extent that the Company enters into co-promotion or other licensing
arrangements, any revenues received by the Company will depend upon the efforts
of third parties, and there can be no assurance that such efforts will be
successful.
 
MANUFACTURING
 
CVT does not currently operate manufacturing facilities for clinical or
commercial production of its proposed products. The Company has no experience
in, and currently lacks the resources and capability to, manufacture any of its
proposed products on a commercial scale. Accordingly, the Company is, and will
continue to be,
 
                                       31
<PAGE>
dependent on corporate partners, licensees or other third parties for clinical
and commercial scale manufacturing. The Company does have experience in the
transfer of synthetic technology from discovery to scale-up manufacturing
facilities, having successfully executed technology transfer for the manufacture
of clinical supplies of one orally administered agent and one intravenously
administered agent. CVT-124 is currently being manufactured to supply clinical
trials by a third party, and the Company is currently negotiating with third
party manufacturers for clinical scale production of ranolazine. There can be no
assurance that the Company will be able to reach satisfactory agreements with
its partners or third parties or that such parties will be able to develop
adequate manufacturing capabilities for commercial scale quantities of products.
 
PATENTS AND PROPRIETARY TECHNOLOGY
 
Patents and other proprietary rights are important to the Company's business.
The Company's policy is to file patent applications and to protect technology,
inventions and improvements to inventions that are commercially important to the
development of its business. The Company also relies on trade secrets,
confidentiality agreements and other protective measures to protect its
technology and proposed products. The Company's failure to obtain patent
protection or otherwise protect its proprietary technology or proposed products
may have a material adverse effect on the Company's competitive position and
business prospects.
 
   
The Company owns four pending patent applications in the United States relating
to an inflammatory factor licensed to Bayer AG, CVT-609/429, CVT-313 and
CVT-634, as well as one foreign patent application with respect to the
inflammatory factor licensed to Bayer. In addition, the Company has acquired an
exclusive license to one United States issued patent, two United States patent
applications and related foreign patent applications related to CVT-124. The
Company also has acquired a license which is exclusive in certain territories to
three United States issued patents, one United States patent application and
related foreign patent applications related to ranolazine. The patent
application process takes several years and entails considerable expense. There
is no assurance that patents will issue from these applications or, if patents
do issue, that the claims allowed will be sufficient to protect the Company's
technology. One of the primary patents relating to ranolazine will expire in May
2003 unless the Company is granted an extension based upon delays in the FDA
approval process.
    
 
Patent applications in the United States are maintained in secrecy until a
patent issues, and the Company cannot be certain that others have not filed
patent applications for technology covered by the Company's pending applications
or that the Company was the first to invent the technology that is the subject
of such patent application. Competitors may have filed applications for, or may
have received patents and may obtain additional patents and proprietary rights
relating to, compounds, products or processes that block or compete with those
of the Company. There can be no assurance that third parties will not assert
patent or other intellectual property infringement claims against the Company
with respect to its products or technology or other matters. There may be third
party patents and other intellectual property relevant to the Company's products
and technology which are not known to the Company.
 
Patent litigation is becoming more widespread in the biopharmaceutical industry.
Litigation may be necessary to defend against or assert claims of infringement,
to enforce patents issued to the Company, to protect trade secrets or know-how
owned by the Company, or to determine the scope and validity of the proprietary
rights of third parties. Although no third party has asserted that the Company
is infringing such third party's patent rights or other intellectual property,
there can be no assurance that litigation asserting such claims will not be
initiated, that the Company would prevail in any such litigation, or that the
Company would be able to obtain any necessary licenses on reasonable terms, if
at all. Any such claims against the Company, with or without merit, as well as
claims initiated by the Company against third parties, can be time-consuming and
expensive to defend or prosecute and to resolve. If other companies prepare and
file patent applications in the United States that claim technology also claimed
by the Company, the Company may have to participate in interference proceedings
to determine priority of invention which could result in substantial cost to the
Company even if the outcome is favorable to the Company.
 
The Company also relies on trade secrets, confidentiality agreements and other
protective measures to protect its technology and proposed products. There can
be no assurance that third parties will not independently develop equivalent
proprietary information or techniques, will not gain access to the Company's
trade secrets or disclose such technology to the public, or that the Company can
maintain and protect unpatented proprietary technology.
 
                                       32
<PAGE>
The Company typically requires its employees, consultants, collaborators,
advisors and corporate partners to execute confidentiality agreements upon
commencement of employment or other relationships with the Company. There can be
no assurance, however, that these agreements will provide meaningful protection
or adequate remedies for the Company's technology in the event of unauthorized
use or disclosure of such information, or that the parties to such agreements
will not breach such agreements.
 
GOVERNMENT REGULATION
 
   
FDA REQUIREMENTS FOR DRUG COMPOUNDS.  The research, testing, manufacture and
marketing of drug products are extensively regulated by numerous governmental
authorities in the United States and other countries. In the United States,
drugs are subject to rigorous regulation by the FDA. The federal Food, Drug and
Cosmetic Act, as amended (the "FDC Act"), and the regulations promulgated
thereunder, and other federal and state statutes and regulations, govern, among
other things, the research, development, testing, manufacture, storage,
recordkeeping, labeling, promotion and marketing and distribution of
pharmaceutical products. Failure to comply with applicable regulatory
requirements may subject a company to administrative or judicially imposed
sanctions such as civil penalties, criminal prosecution, injunctions, product
seizure or detention, product recalls, total or partial suspension of product,
and FDA refusal to approve pending NDA applications or NDA supplements to
approved applications.
    
 
The steps ordinarily required before a new pharmaceutical product may be
marketed in the United States include: (i) preclinical laboratory tests, IN VIVO
preclinical studies and formulation studies; (ii) the submission to the FDA of
an IND, which must become effective before clinical testing may commence; (iii)
adequate and well-controlled clinical trials to establish the safety and
effectiveness of the drug for each indication; (iv) the submission of a NDA to
the FDA; and (v) FDA review and approval of the NDA prior to any commercial sale
or shipment of the drug. Preclinical tests include laboratory evaluation of
product chemistry and formulation, as well as animal studies to assess the
potential safety and efficacy of the product. Preclinical tests must be
conducted in compliance with Good Laboratory Practice regulations and compounds
for clinical use must be formulated according to cGMP requirements. The results
of preclinical testing are submitted to the FDA as part of an IND. A 30-day
waiting period after the filing of each IND is required prior to the
commencement of clinical testing in humans. If the FDA has not commented on or
questioned the IND within this 30-day period, clinical studies may begin. If the
FDA has comments or questions, the questions must be answered to the
satisfaction of the FDA before initial clinical testing can begin. In addition,
the FDA may, at any time, impose a clinical hold on ongoing clinical trials. If
the FDA imposes a clinical hold, clinical trials cannot commence or recommence
without FDA authorization and then only under terms authorized by the FDA. In
some instances, the IND application process can result in substantial delay and
expense.
 
   
Clinical trials involve the administration of the investigational new drug to
healthy volunteers or patients under the supervision of a qualified principal
investigator. Clinical trials are conducted in accordance with Good Clinical
Practice regulations under protocols detailing the objectives of the study, the
parameters to be used in monitoring safety and the effectiveness criteria to be
evaluated. Each protocol must be submitted to the FDA as part of the IND.
Further, each clinical study must be conducted under the auspices of an
independent Institutional Review Board ("IRB") at the institution at which the
study will be conducted. The IRB will consider, among other things, ethical
factors, the safety of human subjects and the possible liability of the
institution. Clinical trials to support NDAs are typically conducted in three
sequential phases, but the phases may overlap. In Phase I, the initial
introduction of the drug into healthy human subjects or patients, the drug is
tested to assess metabolism, pharmacokinetics and pharmacological actions and
safety, including side effects associated with increasing doses. Phase II
usually involves studies in a limited patient population to (i) determine the
efficacy of the drug in specific, targeted indications, (ii) determine dosage
tolerance and optimal dosage and (iii) identify possible adverse effects and
safety risks. If a compound is found to be effective and to have an acceptable
safety profile in Phase II evaluations, Phase III trials are undertaken to
further evaluate clinical efficacy and to further test for safety within an
expanded patient population at geographically dispersed clinical study sites.
There can be no assurance that Phase I, Phase II or Phase III testing will be
completed successfully within any specified time period, if at all, with respect
to any of the Company's products subject to such testing.
    
 
                                       33
<PAGE>
After completion of the required clinical testing, generally an NDA is
submitted. FDA approval of the NDA is required before marketing may begin in the
United States. The NDA must include the results of extensive clinical and other
testing and the compilation of data relating to the product's chemistry,
pharmacology and manufacture, the cost of all of which is substantial. The FDA
reviews all NDAs submitted before it accepts them for filing and may request
additional information rather than accepting an NDA for filing. In such an
event, the NDA must be resubmitted with the additional information and, again,
is subject to review before filing. Once the submission is accepted for filing,
the FDA begins an in-depth review of the NDA. Under the FDC Act, the FDA has 180
days in which to review the NDA and respond to the applicant. The review process
is often significantly extended by FDA requests for additional information or
clarification regarding information already provided in the submission. The FDA
may refer the application to the appropriate advisory committee, typically a
panel of clinicians, for review, evaluation and a recommendation as to whether
the application should be approved. The FDA is not bound by the recommendation
of an advisory committee. If FDA evaluations of the NDA and the manufacturing
facilities are favorable, the FDA may issue either an approval letter or an
approvable letter, which usually contains a number of conditions that must be
met in order to secure final approval of the NDA. When and if those conditions
have been met to the FDA's satisfaction, the FDA will issue an approval letter,
authorizing commercial marketing of the drug for certain indications. As a
condition of NDA approval, the FDA may require postmarketing testing and
surveillance to monitor the drug's safety or efficacy. If the FDA's evaluation
of the NDA submission or manufacturing facilities is not favorable, the FDA may
refuse to approve the NDA or issue a not approvable letter, outlining the
deficiencies in the submission and often requiring additional testing or
information. Notwithstanding the submission of any requested additional data or
information in response to an approvable or not approvable letter, the FDA
ultimately may decide that the application does not satisfy the regulatory
criteria for approval. Once granted, product approvals may be withdrawn if
compliance with regulatory standards is not maintained or problems occur
following initial marketing.
 
MANUFACTURING.  Each domestic drug manufacturing facility must be registered
with FDA. Domestic drug manufacturing establishments are subject to periodic
inspection by the FDA and must comply with cGMP. Further, the Company or its
third party manufacturer must pass a preapproval inspection of its manufacturing
facilities by the FDA before obtaining marketing approval of any products. To
supply products for use in the United States, foreign manufacturing
establishments must comply with cGMP and are subject to periodic inspection by
the FDA or corresponding regulatory agencies in countries under reciprocal
agreements with the FDA. Drug product manufacturing establishments located in
California must be licensed by the State of California in compliance with local
regulatory requirements, and other states may have comparable regulations. The
Company uses and will continue to use third party manufacturers to produce its
products in clinical and commercial quantities. There can be no guarantee that
future FDA inspections will proceed without any compliance issues requiring the
expenditure of money or other resources.
 
   
FOREIGN REGULATION OF DRUG COMPOUNDS.  Whether or not FDA approval has been
obtained, approval of a product by comparable regulatory authorities may be
necessary in foreign countries prior to the commencement of marketing of the
product in such countries. The approval procedure varies among countries, can
involve additional testing, and the time required may differ from that required
for FDA approval. Although there are some procedures for unified filings for
certain European countries with the sponsorship of the country which first
granted marketing approval, in general each country has its own procedures and
requirements, many of which are time consuming and expensive. Thus, there can be
substantial delays in obtaining required approvals from foreign regulatory
authorities after the relevant applications are filed. In Europe, marketing
authorizations may be submitted at either a centralized, a decentralized or a
national level. The centralized procedure is mandatory for the approval of
biotechnology products and provides for the grant of a single marketing
authorization which is valid in all European Community member states. As of
January 1995, a mutual recognition procedure is available at the request of the
applicant for all medicinal products which are not subject to the centralized
procedure. The Company will choose the appropriate route of European regulatory
filing to accomplish the most rapid regulatory approvals. There can be no
assurance that the chosen regulatory strategy will secure regulatory approvals
on a timely basis or at all.
    
 
HAZARDOUS MATERIALS.  The Company's research and development processes involve
the controlled use of hazardous materials, chemicals and radioactive materials
and produce waste products. The Company is subject to federal, state and local
laws and regulations governing the use, manufacture, storage, handling and
disposal of
 
                                       34
<PAGE>
such materials and waste products. Although the Company believes that its safety
procedures for handling and disposing of such materials comply with the
standards prescribed by such laws and regulations, the risk of accidental
contamination or injury from these materials cannot be eliminated completely. In
the event of such an accident, the Company could be held liable for any damages
that result and any such liability could exceed the resources of the Company.
Although the Company believes that it is in compliance in all material respects
with applicable environmental laws and regulations, there can be no assurance
that it will not be required to incur significant costs to comply with
environmental laws and regulations in the future, or that the operations,
business or assets of the Company will not be materially adversely affected by
current or future environmental laws or regulations.
 
COMPETITION
 
The pharmaceutical and biopharmaceutical industries are subject to intense
competition and rapid and significant technological change. While several of
CVT's products target diseases for which there are presently no effective
therapies, CVT nevertheless is aware of companies which are developing products
that will compete for the same disease markets. For example, Kyowa Hakko Co.,
Ltd., Fujisawa Pharmaceutical, Japan and Discovery Therapeutics, Inc., are each
developing adenosine A(1) receptor antagonists. In addition, Sandoz and Glaxo
Wellcome P.L.C. both have adenosine A(1) receptor agonists under development. If
regulatory approvals are received, ranolazine may compete with several classes
of existing drugs for the treatment of angina, some of which are available in
generic form, including calcium channel blockers, beta blockers and nitrates.
There are also non-pharmacologic treatments such as coronary artery bypass
grafting ("CABG") and percutaneous transluminal coronary angioplasty ("PTCA").
However, for those patients who do not respond adequately to existing therapies
and remain symptomatic despite maximal treatment with existing anti-anginal
drugs and who are not candidates for CABG or PTCA, there is no currently
effective treatment. In refractory patients who are candidates for CABG or PTCA,
there is no effective pharmacologic treatment available. In the treatment of
intermittent claudication, ranolazine may compete with Trental, an FDA approved
drug developed by Hoechst Marion Roussel, Inc., beraprost, a prostaglandin being
developed by Bristol-Myers Squibb, Cilostazol, a prostaglandin E(1) derivative
being developed by Otsuka Pharmaceutical Co., Ltd., and L-carnitine, an amino
acid derivative being developed by Sigma Tau Pharmaceuticals, Inc.
 
CVT believes that the principal competitive factors in the markets for
ranolazine and CVT-124 will include the length of time to receive regulatory
approval, product performance, product price, product supply, marketing and
sales capability and enforceability of patent and other proprietary rights. CVT
believes that it is or will be competitive with respect to these factors.
Nonetheless, because the Company's products are still under development, the
relative competitive position of the Company in the future is difficult to
predict.
 
The Company expects that the pharmaceutical and biopharmaceutical industries
will continue to experience rapid technological development which may render the
Company's potential products non-competitive or obsolete. Many current and
potential competitors have substantially greater product development
capabilities and financial, marketing, scientific, and human resources than the
Company. Other companies may succeed in developing products earlier than the
Company, obtaining approvals for such products from the FDA more rapidly than
the Company or developing products that are safer and more effective than those
under development or proposed to be developed by the Company. While the Company
will seek to expand its technological capabilities in order to remain
competitive, there can be no assurance that research and development by others
will not render its technology or potential products obsolete or non-competitive
or result in treatments or cures superior to any therapy developed by the
Company, or that therapy developed by the Company will be preferred to any
existing or newly developed technologies.
 
PRODUCT LIABILITY INSURANCE
 
The manufacture and sale of human therapeutic products involve an inherent risk
of product liability claims and associated adverse publicity. The Company has
only limited product liability insurance for clinical trials and no commercial
product liability insurance. There can be no assurance that it will be able to
maintain existing or obtain additional product liability insurance on acceptable
terms or with adequate coverage against potential liabilities. Such insurance is
expensive, difficult to obtain and may not be available in the future on
acceptable terms, or at all. An inability to obtain sufficient insurance
coverage on reasonable terms or to otherwise protect against potential product
liability claims could prevent or inhibit the commercialization of the Company's
 
                                       35
<PAGE>
potential products. A product liability claim brought against the Company in
excess of its insurance coverage, if any, or a product withdrawal could have a
material adverse effect upon the Company's business, financial condition and
results of operations.
 
EMPLOYEES
 
   
As of September 30, 1996, CVT employed 44 individuals full-time, including 15
who hold doctoral degrees. Of the Company's total work force, 30 employees are
engaged in or directly support research and development activities and 14 are
engaged in business development, finance and administrative activities. The
Company's employees are not represented by a collective bargaining agreement.
The Company believes its relations with its employees are good.
    
 
FACILITIES
 
The Company currently leases a 61,081 square foot building in Palo Alto,
California, of which approximately 33,783 square feet are subleased to two third
parties. The initial term of the lease expires in February 2002 with an option
to renew for five years, and the subleases expire in March 1997 and March 1998,
respectively. CVT believes that this facility will be adequate to meet the
Company's needs for the foreseeable future.
 
SCIENTIFIC ADVISORY BOARD
 
   
CVT's Scientific Advisory Board ("SAB") consists of academic and industry
experts in the fields of medicine, chemistry and molecular and cellular biology.
The SAB reviews and evaluates the Company's research programs and advises the
Company with respect to technical matters. Each SAB member has entered into a
consulting agreement with the Company specifying the terms and scope of the
advisory relationship. All SAB members own shares or have been granted options
to acquire Common Stock of the Company. All of the SAB members are employed by
employers other than the Company and may have other commitments and consulting
contracts with other entities which may compete for such member's time with
their obligations to the Company. The Company's Scientific Advisory Board

BOARD COMPOSITION
 
   
The Company currently has authorized seven directors. These directors are
elected to serve until the next annual meeting of stockholders or until their
earlier resignation or removal. In accordance with the terms of the Company's
Restated Certificate of Incorporation, at such time as the Company is no longer
subject to Section 2115 of the California Corporations Code, the terms of office
of the Board of Directors will be divided into three classes: Class I, whose
term will expire at the annual meeting of stockholders to be held in 1997; Class
II, whose term will expire at the annual meeting of stockholders to be held in
1998; and Class III, whose term will expire at the annual meeting of
stockholders to be held in 1999. See "Description of Capital Stock - General."
The Class I directors are Mr. Gutshall and Dr. Sevastopoulos, the Class II
directors are Drs. McNeil and Read, and the Class III directors are Dr. Lange
and Messrs. Colella and Stein. At each annual meeting of stockholders after the
initial classification, the successors to directors whose term will then expire
will be elected to serve from the time of election and qualification until the
third annual meeting following election. In addition, the Company's Restated
Certificate of Incorporation provides that the authorized number of directors
may be changed only by resolution of the Board of Directors. Any additional
directorships resulting from an increase in the number of directors will be
distributed among the three classes so that, as nearly as possible, each class
will consist of one-third of the directors. This classification of the Board of
Directors may have the effect of delaying or preventing changes in control or
management of the Company. Although directors of the Company may be removed for
cause by the affirmative vote of the holders of a majority of the voting power
of all the then-outstanding shares of voting stock of the Corporation entitled
to vote at an election of directors (the "Voting Stock"), the Company's Restated
Certificate of Incorporation provides that holders of two-thirds of the Voting
Stock must vote to approve the removal of a director without cause.
    
 
BOARD COMMITTEES
 
The Audit Committee of the Company's Board of Directors consists of Messrs.
Colella, Gutshall and Stein and Dr. McNeil. The Audit Committee reviews the
internal accounting procedures of the Company and consults with and reviews the
services provided by the Company's independent auditors.
 
The Compensation Committee of the Company's Board of Directors currently
consists of Mr. Colella and Drs. Read and Sevastopoulos. The Compensation
Committee reviews and recommends to the Board the compensation and benefits of
all officers of the Company and reviews general policy relating to compensation
and benefits of employees of the Company. The Compensation Committee also
administers the issuance of stock options and other awards under the Company's
stock plans.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
From the Company's inception through 1994, the Board of Directors made all
determinations with respect to executive officer compensation. In the fiscal
year ended December 31, 1995, a Compensation Committee consisting of Mr.
Colella, Dr. Lange, the Company's Chief Executive Officer, and Drs. Read and
Sevastopoulos, made all determinations relating to executive officer
compensation.
 
DIRECTOR COMPENSATION
 
   
Other than Isaac Stein and Barbara McNeil, who receive $1,000 per meeting
attended, the Company's directors currently do not receive cash compensation for
service on the Board of Directors or any committee thereof, but directors may be
reimbursed for reasonable expenses in connection with attendance at Board and
committee meetings.
    
 
   
In July 1994, the Board of Directors adopted and in July 1995, the stockholders
approved the Non-Employee Directors' Stock Option Plan (the "Directors' Plan").
The Directors' Plan was amended and restated in September 1996, subject to
stockholder approval. The Company has reserved 250,000 shares of Common Stock
for issuance under the Directors' Plan. The Directors' Plan provides for
automatic grants of options to purchase shares of Common Stock to non-employee
directors of the Company ("Non-Employee Directors"). Pursuant to the terms of
the Directors' Plan, each Non-Employee Director is automatically granted an
option to purchase shares of
    
 
                                       40
<PAGE>
   
Common Stock. Commencing with the adoption of the Directors' Plan, each newly
elected Non-Employee Director was granted an option to purchase 1,000 shares of
Common Stock, and on each anniversary of the adoption of the Directors' Plan,
each Non-Employee Director was granted an option to purchase 500 shares. These
options vest at the rate of 1/36 per month. Upon the amendment and restatement
of the Directors' Plan, each Non-Employee Director was granted an option to
purchase 15,000 shares, subject to stockholder approval. Each subsequently
elected Non-Employee Director will also be granted an option to purchase 15,000
shares at his or her election. These options for 15,000 shares vest as to 33.33%
of the shares 12 months from the date of grant, and at the rate of 1/36 per
month thereafter, if the Non-Employee Director provides services to the Company
or its affiliates through the applicable vesting date. In addition, at each
annual meeting of the Company's stockholders after the effectiveness of this
Offering, each Non-Employee Director will be granted an option to purchase 5,000
shares, which will vest 12 months from the date of grant if the Non-Employee
Director provides services to the Company or its affiliates through such date.
As of September 30, 1996, options to purchase 100,000 shares have been granted
under the Directors' Plan.
    
 
The exercise price of options granted under the Directors' Plan must equal the
fair market value of the Common Stock on the date of grant; provided, however,
that prior to the September 1996 amendment and restatement of the Directors'
Plan, the exercise price of options granted to any person possessing more than
10% of the total combined voting power of all classes of stock of the Company or
of any of its affiliates was 110% of the fair market value on the date of grant.
No option granted under the Directors' Plan may be exercised after the
expiration of ten years from date it was granted. No option may be transferred
by the optionee other than by will or the laws of descent or distribution,
provided that an optionee may designate a beneficiary who may exercise the
option following the optionee's death. The Directors' Plan will terminate in
September 2006, unless earlier terminated by the Board.
 
   
Upon certain changes in control of Company, outstanding options will be assumed
or substituted by the surviving corporation.
    
 
In July 1994, the Company entered into a Consulting Agreement for Individual
Consultants with Barbara J. McNeil, M.D., Ph.D., a director of the Company,
pursuant to which Dr. McNeil agreed to serve on the Board of Directors and to
provide other advice and consultation. Under the terms of the agreement, the
Company agreed to pay a fixed fee of $1,000 per day as compensation for Dr.
McNeil's services. In the fiscal year ended December 31, 1995, Dr. McNeil
received $10,000 as compensation for her services. The Company may terminate
this agreement for any reason upon written notice. In addition, in July 1994,
the Board of Directors of the Company granted Dr. McNeil an option to purchase
2,500 shares of Common Stock at an exercise price of $2.50 per share. The option
vests over a three year period. As a result of this option grant, Dr. McNeil did
not receive an initial option to purchase 1,000 shares of Common Stock pursuant
to the Directors' Plan upon joining the Board.
 
In March 1995, the Company entered into a Consulting Agreement for Individual
Consultants with Isaac Stein, a director of the Company, pursuant to which Mr.
Stein agreed to provide advice and consultation to the Company. As compensation
for his services in the fiscal year ended December 31, 1995, Mr. Stein received
$3,000 and an option to purchase 9,000 shares of Common Stock outside the
Directors' Plan at an exercise price of $2.50 per share. The option vests over a
three year period. The Company may terminate the agreement for any reason upon
written notice.
 
   
In September 1996, in consideration for consulting services, the Company granted
an option to purchase 10,000 shares of Common Stock to Mr. Stein and an option
to purchase 5,000 shares of Common Stock to Dr. Sevastopoulos, at an exercise
price of $2.50 per share. The option grants vest over a three year period. In
addition, the Company agreed to pay Dr. Sevastopoulos $30,000 for consulting
services rendered.
    
 
See "Management - Employment Agreements and Termination of Employment
Agreements" for description of the Separation and Consulting Agreement with
Thomas L. Gutshall.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
As permitted by the Delaware Law, the Company's Restated Certificate of
Incorporation provides that no director of the Company will be personally liable
to the Company or its stockholders for monetary damages for breach of
 
                                       41
<PAGE>
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Company or to its stockholders, (ii) for acts
or omissions not made in good faith or which involved intentional misconduct or
a knowing violation of law, (iii) under Section 174 of the Delaware Law,
relating to prohibited dividends or distributions or the repurchase or
redemption of stock, or (iv) for any transaction from which the director derives
an improper personal benefit. In addition, the Company's Restated Certificate of
Incorporation provides that any director or officer who was or is a party or is
threatened to be made a party to any action or proceeding by reason of his or
her services to the Company will be indemnified to the fullest extent permitted
by the Delaware Law.
 
The Company has entered into indemnification agreements with each of its
directors and officers for the indemnification of and advancement of expenses to
such persons to the full extent permitted by law and the Company currently
maintains directors' and officers' liability insurance.
 
There is no pending litigation or proceeding involving a director or officer of
the Company as to which indemnification is being sought, nor is the Company
aware of any pending or threatened litigation that may result in claims for
indemnification by any director or officer.

(1) Based on an aggregate of options to purchase 392,986 shares of the Company's
    Common Stock granted to employees and directors of, and consultants to, the
    Company during fiscal year ended December 31, 1995, including the Named
    Executive Officers.
 
(2) The exercise price per share of each option was equal to the fair market
    value of the Common Stock on the date of grant as determined by the Board of
    Directors.
 
   
(3) The potential realizable value is calculated based on the term of the option
    at its time of grant (ten years). It is calculated assuming that the assumed
    initial public offering price of $13.00 per share appreciates from the date
    of grant at the indicated annual rate compounded annually for the entire
    term of the option and the option is exercised and sold on the last day of
    its term for the appreciated stock price. No gain to the optionee is
    possible unless the stock price increases over the option term.
    
 
(4) Twenty-four percent of the option vests one year from the vesting
    commencement date, with subsequent vesting at a rate of two percent each
    month for 38 months. The option expires ten years from the date of grant or
    earlier upon termination of employment.
 
   
(5) Mr. Gutshall's option for 7,500 shares is fully vested. Under Mr. Gutshall's
    Separation and Consulting Agreement, (i) the 5,000 share option vested as to
    2,000 shares through September 2, 1996 and 3,000 shares were repurchased by
    the Company for an aggregate purchase price of $750; (ii) the 65,000 share
    option vested as to 26,000 shares through September 2, 1996 and 39,000
    shares were canceled on September 2, 1996.
    
 
(6) In connection with the termination of Mr. Hirsch's employment, the option to
    purchase 23,600 shares was canceled on May 1, 1996.

(1)  Value realized and value of unexercised in-the-money options is based on a
     value of $13.00 per share of the Company's Common Stock, the assumed
     initial public offering price, even though at the time of grant the fair
     market value of the Common Stock was determined by the Board of Directors
     to range from $0.80 to $2.50 per share. Amounts reflected are based on the
     assumed value minus the exercise price multiplied by the number of shares
     acquired on exercise and do not indicate that the optionee sold such stock.

EMPLOYMENT AGREEMENTS AND TERMINATION OF EMPLOYMENT AGREEMENTS
 
In January 1996, the Company entered into a letter agreement with Mark B.
Hirsch. Pursuant to the agreement, the Company accepted Mr. Hirsch's resignation
as Vice President, Corporate Development effective October 31, 1995, but
retained Mr. Hirsch as an employee of the Company through April 30, 1996. Under
the terms of the agreement, Mr. Hirsch was compensated through April 30, 1996 at
the same compensation level in effect prior to his resignation.
 
In September 1996, the Company entered into a Separation and Consulting
Agreement with Thomas L. Gutshall. Pursuant to the agreement, the Company
accepted Mr. Gutshall's resignation as President and Chief Operating Officer
effective September 2, 1996. Mr. Gutshall agreed to continue to serve as a
member of the Company's Board of Directors and to serve as a consultant to the
Company through December 31, 1998. Under the terms of the agreement, Mr.
Gutshall will receive consulting fees starting at $8,750 per month in September
1996 and declining to $3,500 per month effective November 1, 1996 and continuing
at that rate thereafter. In addition, Mr. Gutshall's stock option grant for
5,000 shares vested as to 2,000 shares through September 2, 1996 and 3,000
shares were repurchased by the Company. His stock option grant for 65,000 shares
vested as to 26,000 shares through September 2, 1996 and 39,000 shares were
canceled on September 2, 1996.
 
Each officer and salaried employee has entered into a standard form of
Employment, Confidential Information and Invention Assignment Agreement which
provides that the employment is at-will, that the employee will not disclose any
confidential information of the Company received during the course of the
employment and that, with certain exceptions, the employee will assign to the
Company any and all inventions conceived or developed during the course of the
employment.
 
401(K) PLAN
 
As of October 1, 1993, the Company adopted a tax-qualified employee savings and
retirement plan (the "401(k) Plan") covering the Company's 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 ($9,500 in 1996) and have the amount of such
reduction contributed to the 401(k) Plan. The 401(k) Plan provides for
additional matching contributions by the Company in an amount determined by the
Company. To date, the Company has not provided any matching contributions. The
trustees under the 401(k) Plan, at the direction of each participant, invest the
assets of the 401(k) Plan in designated investment options. The 401(k) Plan is
intended to qualify under Section 401 of the Internal Revenue Code of 1986, as
amended (the "Code"), so that contributions to the 401(k) Plan, and income
earned on the 401(k) Plan contributions, are not taxable until withdrawn, and so
that the contributions by the Company will be deductible when made.
 
STOCK PLANS
 
   
1994 EQUITY INCENTIVE PLAN.  The Company's 1994 Equity Incentive Plan (the
"Incentive Plan") was adopted by the Board of Directors in February 1994,
approved by the stockholders in March 1994, amended by the Board in February
1995 and April 1995 and subsequently approved by the stockholders in July 1995.
The Incentive Plan was amended in September 1996, subject to stockholder
approval. There are currently 800,000 shares of Common Stock authorized for
issuance under the Incentive Plan.
    
 
The Incentive Plan provides for the grant of incentive stock options under the
Code and stock appreciation rights appurtenant thereto, to employees (including
officers and employee-directors) and nonstatutory stock options, restricted
stock purchase awards and stock bonuses to employees, directors and consultants.
The Incentive Plan is administered by the Compensation Committee of the Board of
Directors, which has been delegated the Board's authority to administer the
Plan. The Compensation Committee 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 terms of stock options granted under the Incentive Plan generally may not
exceed 10 years. The exercise price for an incentive stock option cannot be less
than 100% of the fair market value of the Common Stock on
 
                                       44
<PAGE>
   
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 option grant. Options granted under the Incentive Plan vest at the
rate specified in the option agreement. Options may include provisions allowing
exercise of any part or all of the options prior to full vesting. Any unvested
shares so purchased shall be subject to a repurchase right in favor of the
Company or to any other restriction the Board determines to be appropriate. No
stock option may be transferred by the optionee other than by will or the laws
of descent or distribution, provided that a nonstatutory stock option may be
transferred pursuant to a domestic relations order and the Board of Directors
may grant a nonstatutory stock option that is transferable, and provided further
that an optionee may designate a beneficiary who may exercise the option
following the optionee's death. An optionee whose relationship with the Company
or any related corporation ceases for any reason (other than by death or
permanent and total disability) may exercise options in the period specified by
the Board following such cessation. Options may be exercised for up to twelve
months after an optionee's relationship with the Company and its affiliates
ceases due to disability, and up to eighteen months following an optionee's
death (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 the Company or any affiliate of the Company, 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. To the extent an optionee would have
the right in any calendar year to exercise for the first time one or more
incentive stock options for shares having an aggregate fair market value (under
all plans of the Company and its affiliates and determined for each share as of
the date the option to purchase the shares was granted) in excess of $100,000,
any such excess options will be treated as nonstatutory stock options. No person
may be granted options and stock appreciation rights covering more than 100,000
shares of Common Stock per calendar year, provided that this limit shall not
apply until the expiration of the transition period under Section 162(m) of the
Code for privately held companies that become publicly held.
 
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 Incentive Plan.
Shares subject to exercised stock appreciation rights shall not again become
available for the grant of new awards.
 
The Board of Directors has the authority, with the consent of affected holders,
to reprice outstanding options and stock appreciation rights and to offer
optionees the opportunity to replace outstanding options or stock appreciation
rights with new options or stock appreciation rights for the same or a different
number of shares.
 
Restricted stock purchase awards granted under the Incentive Plan may be granted
pursuant to a repurchase option in favor of the Company in accordance with a
vesting schedule and at a price determined by the Board of Directors. Stock
bonuses may be awarded in consideration of past services without a purchase
payment. Rights under a stock bonus or restricted stock bonus agreement may not
be transferred except where such assignment is required by law or expressly
authorized by the terms of the applicable stock bonus or restricted stock
purchase agreement. Stock appreciation rights granted under the Incentive Plan
may be tandem rights, concurrent rights or independent rights.
 
   
Upon certain changes in control of the Company, not subject to Board approval,
outstanding options shall be fully vested. In addition, outstanding stock awards
shall be assumed, substituted or continued by the surviving corporation or
parent thereof. In the event the surviving corporation or its parent refuses to
assume, substitute or continue such awards, then such awards shall be terminated
if not exercised prior to the change of control.
    
 
   
As of September 30, 1996, options to purchase 649,214 shares of Common Stock had
been granted under the Incentive Plan, at a weighted average exercise price of
$2.49, 75,406 shares of Common Stock had been issued upon the exercise of
options, options to purchase 425,798 shares of Common Stock were outstanding and
298,796 shares remained available for future grant. As of September 30, 1996, no
restricted stock awards, stock appreciation rights or stock bonuses had been
granted under the Incentive Plan.
    
 
The Incentive Plan will terminate in September 2006 unless sooner terminated by
the Board of Directors.

1992 STOCK OPTION PLAN.  The Company's 1992 Stock Option Plan (the "1992 Stock
Plan") was adopted by the Board of Directors in November 1992, amended in March
1993 and September 1993, approved by its stockholders in November 1993 and
amended in September 1996, subject to stockholder approval. The Company has
reserved 345,000 shares of Common Stock for issuance under the 1992 Stock Plan.
 
The 1992 Stock Plan provides for grants of incentive stock options to employees
and nonstatutory stock options to employees, directors and consultants of the
Company. Shares subject to options which expire or otherwise terminate without
having been exercised may again be subject to options under the 1992 Stock Plan.
The 1992 Stock Plan is administered by the Compensation Committee of the Board
of Directors, which 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 a stock option granted under the 1992 Stock Plan generally may not
exceed 10 years. Options granted pursuant to the 1992 Stock Plan become
exercisable at a rate specified in the option agreement. Options may include
provisions allowing exercise of any part or all of the options prior to full
vesting. Any unvested shares so purchased shall be subject to a repurchase right
in favor of the Company or to any other restriction the Board determines to be
appropriate. The exercise price of options granted under the 1992 Stock Plan is
determined by the Board of Directors; provided that, in the case of an incentive
stock option, the exercise price cannot be less than 100% of the fair market
value of the Common Stock on the date of grant or, in the case of 10%
stockholders, not less than 110% of the fair market value of the Common Stock on
the date of grant, and in the case of a nonstatutory stock option, the exercise
price cannot be less than 85% of the fair market value of the Common Stock on
the date of grant. To the extent an optionee would have the right in any
calendar year to exercise for the first time one or more incentive stock options
for shares having an aggregate fair market value (under all plans of the Company
and its affiliates and determined for each share as of the date the option to
purchase the shares was granted) in excess of $100,000, any such excess options
will be treated as nonstatutory stock options. No option may be transferred by
the optionee other than by will or the laws of descent or distribution, provided
that an optionee may designate a beneficiary who may exercise the option
following the optionee's death. An optionee whose employment with the Company
ceases for any reason (other than by death or permanent and total disability)
may exercise options in the three month period following such termination
(unless such options terminate or expire sooner by their terms). The three month
post-termination exercise period is extended to 12 months for termination due to
death or disability.
 
Upon certain changes in control of the Company, not subject to Board approval,
outstanding options shall be fully vested and shall be assumed, substituted or
continued by the surviving corporation or parent thereof. In the event the
surviving corporation or its parent refuses to assume, substitute or continue
such options, then such options shall be terminated if not exercised prior to
the change of control.
 
   
As of September 30, 1996, options to purchase 448,566 shares of Common Stock had
been granted under the 1992 Stock Plan, at a weighted exercise price of $1.41,
80,428 shares of Common Stock had been issued upon the exercise of options,
options to purchase 263,540 shares of Common Stock were outstanding and 1,032
shares remained available for future grant.
    
 
The 1992 Stock Plan will terminate in November 2002, unless terminated sooner by
the Board of Directors.
 
   
EMPLOYEE STOCK PURCHASE PLAN.  In September 1996, the Company's Board of
Directors approved the Employee Stock Purchase Plan (the "Purchase Plan")
covering an aggregate of 150,000 shares of Common Stock. The Purchase Plan is
intended to qualify as an employee stock purchase plan within the meaning of
Section 423 of the Code. Under the Purchase Plan, the Board of Directors may
authorize participation by eligible employees, including officers, in periodic
offerings following the adoption of the Purchase Plan. The offering period for
any offering will be no more than 27 months. The Board of Directors has not
currently authorized an offering under the Purchase Plan.
    
 
   
Employees are eligible to participate if they are employed by the Company or an
affiliate of the Company designated by the Board of Directors provided that
employees who are not employed at least 20 hours per week or five months per
year may be excluded. Employees who participate in an offering can have up to
15% (or such lower percentage specified by the Board of Directors) of their
earnings withheld pursuant to the Purchase Plan
    
 
                                       46
<PAGE>
   
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 Purchase Plan may not be less than 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 an offering at
any time during the offering period, and participation will end automatically on
termination of employment with the Company. Rights under the Purchase Plan may
not be transferred by employees other than by will or the laws of descent or
distribution, provided that an employee may designate a beneficiary who may
receive shares and cash, if any, from the employee's account under the Purchase
Plan in the event of such employee's death.
    
 
   
In the event of certain changes of control, the Company and the 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 the Board 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 Purchase Plan will terminate at the Board's discretion.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
Upon the closing of this Offering, the authorized capital stock of the Company
will consist of 30,000,000 shares of Common Stock, $.001 par value, and
5,000,000 shares of Preferred Stock, $.001 par value.
 
The Company may be subject to Section 2115 of the California Corporations Code
("Section 2115"). Section 2115 provides that, regardless of a company's legal
domicile, certain provisions of California corporate law will apply to that
company if the Company meets certain requirements relating to its property,
payroll and sales in California and if more than one-half of its outstanding
voting securities are held of record by persons having addresses in California.
Section 2115 limits the ability of the Company to, among other things, elect a
classified board of directors. The Company will not be subject to Section 2115
(i) at such time as the Company is qualified for trading as a national market
security on the Nasdaq system and has 800 stockholders as of the record date of
its most recent annual meeting or (ii) at the end of any income year during
which a certificate of state connections pursuant to Section 2108 of the
California Corporations Code shall have been filed showing that less than
one-half of its outstanding voting securities are held of record by persons
having addresses in California or that one of the other tests of Section 2115 is
not met. The Company expects that it will no longer be subject to Section 2115
by the record date of its 1997 annual meeting of stockholders.
 
COMMON STOCK
 
   
As of September 30, 1996, there were 4,450,356 shares of Common Stock
outstanding (assuming the conversion of all outstanding Preferred Stock upon the
closing of this Offering) held of record by approximately 220 stockholders.
    
 
The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. The holders of
Common Stock are entitled to receive ratably such dividends as may be declared
by the Board of Directors out of funds legally available therefor. See "Dividend
Policy." In the event of a liquidation, dissolution or winding up of the
Company, holders of the Common Stock are entitled to share ratably in all assets
remaining after payment of liabilities. Holders of Common Stock have no
preemptive rights and no right to convert their Common Stock into any other
securities. There are no redemption or sinking fund provisions applicable to the
Common Stock. All outstanding shares of Common Stock are, and all shares of
Common Stock to be outstanding upon completion of this Offering will be, fully
paid and nonassessable.
 
PREFERRED STOCK
 
The Board of Directors has the authority, without further action by the
stockholders, to issue up to 5,000,000 shares of Preferred Stock in one or more
series and to fix the rights, preferences, privileges and restrictions thereof,
including dividend rights, conversion rights, voting rights, terms of
redemption, liquidation preferences, sinking fund terms and the number of shares
constituting any series or the designation of such series, without any further
vote or action by stockholders. The issuance of Preferred Stock could adversely
affect the voting power of holders of Common Stock and the likelihood that such
holders will receive dividend payments and payments upon liquidation and could
have the effect of delaying, deferring or preventing a change in control of the
Company. The Company has no present plan to issue any shares of Preferred Stock.
 
WARRANTS
 
   
As of September 30, 1996, the Company had outstanding warrants to purchase
570,754 shares of Common Stock at exercise prices ranging from $2.50 to $25.00
per share. In addition, in December 1995, the Company issued a warrant to
purchase 2,500 units at a price of $.50 per unit to Cooley Godward LLP, the
Company's counsel, with each unit consisting of 1 share of Common Stock and one
warrant to purchase 1/2 share of Common Stock at an exercise price of $20.00 per
share. Each warrant is exercisable immediately with the exception of two
warrants to purchase an aggregate of 84,500 shares of Common Stock which are not
exercisable until after September 15, 1997. Each warrant contains provisions for
the adjustment of the exercise price and the aggregate number of shares issuable
upon the exercise of the warrant under certain circumstances, including stock
dividends, stock splits, reorganizations and reclassifications. Each warrant may
be exercised, without the payment of cash, for a
    
 
                                       54
<PAGE>
number of shares of Common Stock determined pursuant to a net issue exercise
formula contained in the warrant. Each warrant holder has certain registration
rights. See "Description of Capital Stock - Registration Rights of Certain
Holders." Generally, the warrants expire at various times from September 1997 to
April 2005.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
   
Following this Offering, holders of 4,030,002 shares of Common Stock and
warrants to purchase 574,504 shares of Common Stock will be entitled to certain
rights with respect to the registration of their shares under the Securities
Act. These rights are provided under the terms of an Investors' Rights
Agreement, dated May 29, 1996, and certain other agreements (the "Agreements").
Pursuant to the terms of the Agreements, if the Company proposes to register any
of its securities under the Securities Act, either for its own account or the
account of others, the holders are entitled to notice of such registration and
are entitled to include, at the Company's expense, their shares of Common Stock;
provided, among other conditions, that the underwriters of any offering have the
right to limit the number of such shares included in such registration or
exclude such shares entirely. The holders may also require the Company, on no
more than one occasion over any twelve month period, at the Company's expense,
to register all or a portion of their shares of Common Stock on Form S-3 when
such form becomes available to the Company, subject to certain conditions and
limitations. Further, holders of 4,030,002 shares of Common Stock and warrants
to purchase 534,504 shares of Common Stock may require the Company, beginning
180 days after the date of the Prospectus, on not more than two occasions, to
file a registration statement under the Securities Act at the Company's expense
with respect to their shares of Common Stock, and the Company is required to use
its best efforts to effect such registration, subject to certain conditions and
limitations. All rights described in this paragraph terminate at such time as
such shares of Common Stock may be sold in the public market.
    
 
DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
The Company is subject to the provisions of Section 203 of the Delaware Law, an
anti-takeover law. In general, the statute prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the business
combination is approved in a prescribed manner. For purposes of Section 203, a
"business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit to the interested stockholder, and an
"interested stockholder" is a person who, together with affiliates and
associates, owns (or within three years prior, did own) 15% or more of the
corporation's voting stock.
 
The Company's Restated Certificate of Incorporation and Restated Bylaws also
require that, effective upon the closing of this Offering, any action required
or permitted to be taken by stockholders of the Company must be effected at a
duly called annual or special meeting of the stockholders and may not be
effected by a consent in writing. In addition, special meetings of the
stockholders of the Company may be called only by the Board of Directors, the
Chairman of the Board, the Chief Executive Officer of the Company or by any
person or persons holding shares representing at least 10% of the outstanding
capital stock. The Company's Restated Certificate of Incorporation also provides
for a classified Board which will be instituted at such time as the Company is
no longer subject to Section 2115 and specifies that the authorized number of
directors may be changed only by resolution of the Board of Directors. See
"Management - Board Composition." These provisions may have the effect of
deterring hostile takeovers or delaying changes in control or management of the
Company.
 
TRANSFER AGENT AND REGISTRAR
 
Norwest Bank Minnesota, N.A. has been appointed as the transfer agent and
registrar for the Company's Common Stock.

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
Upon completion of this Offering, the Company will have 6,950,356 shares of
Common Stock outstanding, assuming the net exercise of certain outstanding
warrants for Common Stock and the conversion of all outstanding Preferred Stock
but no exercise of other outstanding warrants and options. Of these shares, the
2,500,000 shares sold in this Offering will be freely transferable without
restriction under the Securities Act unless they are held by "affiliates" of the
Company as that term is defined in Rule 144 under the Securities Act. The
remaining 4,450,356 shares of Common Stock (the "Restricted Shares") held by
officers, directors, employees, consultants and other stockholders of the
Company were sold by the Company in reliance on exemptions from the registration
requirements of the Securities Act and are "restricted securities" within the
meaning of Rule 144 under the Securities Act and may not be sold publicly unless
they are registered under the Securities Act or are sold pursuant to Rule 144 or
another exemption from registration.
    
 
   
The officers, directors, employees and certain stockholders of the Company have
agreed not to sell their shares without the prior written consent of J.P. Morgan
Securities Inc. for a period of 180 days from the date of this Prospectus. Upon
completion of the Offering, approximately 92,785 shares will be eligible for
sale in the public market immediately following the Offering. Beginning 180 days
after commencement of this Offering, approximately 2,482,503 Restricted Shares
that are subject to lock-up agreements (as described below under "Underwriting")
will become eligible for sale in the public market subject to Rule 144 and Rule
701 under the Securities Act. The remaining approximately 1,875,068 Restricted
Shares, which are also subject to such lock-up agreements, will have been held
for less than two years or, in the case of affiliates, for less than three
years, upon the expiration of such lock-up agreements and will become eligible
for sale under Rule 144 at various dates thereafter as the holding period
provisions of Rule 144 are satisfied.
    
 
   
In general, under Rule 144 as currently in effect, a person (or persons whose
shares are aggregated) who has beneficially owned Restricted Shares for at least
two years, including persons who may be deemed "affiliates" of the Company, is
entitled to sell, within any three month period commencing 90 days after this
Offering, a number of shares that does not exceed the greater of 1% of the
number of shares of Common Stock then outstanding (approximately 70,000 shares
immediately after this Offering, assuming no exercise of the Underwriters' over-
allotment option) or the average weekly trading volume of the Common Stock as
reported through the Nasdaq National Market during the four calendar weeks
preceding the filing of a Form 144 with respect to such sale. Sales under Rule
144 are also subject to certain manner of sale provisions and notice
requirements and to the availability of current public information about the
Company. In addition, a person who is not deemed to have been an affiliate of
the Company at any time during the 90 days preceding a sale, and who has
beneficially owned for at least three years the shares proposed to be sold,
would be entitled to sell such shares under Rule 144(k) without regard to the
requirements described above.
    
 
Under Rule 701 under the Securities Act, any employee, officer or director of or
consultant to the Company, who is not an affiliate of the Company, and who
purchased shares pursuant to a written compensatory plan or contract, including
the Company's stock option plans, is entitled to sell such shares without having
to comply with the public information, holding period, volume limitation or
notice provisions of Rule 144, and affiliates of the Company are permitted to
sell such shares without having to comply with the Rule 144 holding period
restrictions, in each case commencing 90 days after this Offering.
 
   
The Company presently intends to file a registration statement under the
Securities Act on Form S-8 to register approximately 1,415,666 shares of Common
Stock subject to outstanding stock options or reserved for issuance under the
Incentive Plan, the 1992 Stock Plan and the Directors' Plan (the "Plans") as
well as stock options granted outside the Plans and shares reserved for issuance
under the Purchase Plan. As of September 30, 1996, 803,338 shares were issuable
upon exercise of currently outstanding options, all of which are subject to the
lock-up agreements described above. Of these shares, 317,093 will be vested 180
days after commencement of this Offering and eligible for sale, subject, in the
case of sales by affiliates, to the volume, manner of sale, notice and public
information requirements of Rule 144. See "Management - Stock Plans" and
"Management - Directors' Compensation."
    
 
                                       56
<PAGE>
   
As of September 30, 1996, 574,504 shares were issuable upon exercise of
currently outstanding warrants of which 490,004 shares are subject to the
lock-up agreements described above. Of these shares, 186,926 will become
eligible for sale in the public markets subject to Rule 144 beginning 180 days
after commencement of this Offering and 387,578 shares will become eligible for
sale subject to Rule 144 at various dates thereafter as the holding provisions
of Rule 144 are satisfied. In addition, 84,500 shares which are not subject to
lock-up agreements will become eligible for sale in the public markets beginning
after September 15, 1997 pursuant to the terms of the individual warrants,
subject to Rule 144.
    
 
   
The holders of 4,030,002 shares of Common Stock and the holders of warrants
exercisable for 574,504 additional shares of Common Stock are entitled to
certain rights with respect to the registration of such shares under the
Securities Act. See "Description of Capital Stock - Registration Rights of
Certain Holders." Registration of such shares under the Securities Act would
result in such shares becoming freely tradable without restriction under the
Securities Act (except for shares purchased by affiliates of the Company)
immediately upon the effectiveness of such registration. If certain of such
holders, by exercising their demand registration rights, cause a larger number
of securities to be registered and sold in the public market, such sales could
have an adverse effect on the market price for the Common Stock. If the Company
were to include in a Company-initiated registration any Registrable Securities
pursuant to the exercise of piggyback registration rights, such sales may have
an adverse effect on the Company's ability to raise needed capital.
    
 
Prior to this Offering, there has been no public market for the Common Stock of
the Company. No predictions can be made of the effect if any, that the sale or
availability for sale of shares of additional Common Stock will have on the
market price of the Common Stock. Nevertheless, sales of a substantial amount of
such shares by existing stockholders or by stockholders purchasing in the
Offering could have a negative impact on the market price of the Common Stock.

The Underwriters propose initially to offer the Common Stock directly to the
public at the price set forth on the cover page of this Prospectus and to
certain dealers at such price less a concession not in excess of     per share.
The Underwriters may allow, and such dealers may reallow, a concession not in
excess of     per share to certain other dealers. After the initial public
offering of the Common Stock, the public offering price and such concession may
be changed.
 
   
The Company has granted to the Underwriters an option, expiring at the close of
business on the 30th day after the date of this Prospectus, to purchase up to
375,000 additional shares of Common Stock at the initial public offering price,
less the underwriting discount. The Underwriters may exercise such option solely
for the purpose of covering over-allotments, if any. To the extent the
Underwriters exercise the option, each Underwriter will have a firm commitment,
subject to certain conditions, to purchase approximately the same percentage of
such additional shares as the number set forth next to such Underwriter's name
in the preceding table bears to the total number of shares of Common Stock
offered hereby.
    
 
The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
   
The Company's officers, directors and certain other stockholders of the Company
have agreed, subject to certain exceptions, not to, directly or indirectly, (i)
sell, grant any option to purchase or otherwise transfer or dispose of any
shares of Common Stock or securities convertible into or exchangeable or
exercisable for shares of Common Stock or file a registration statement under
the Securities Act with respect to the foregoing or (ii) enter into any swap or
other agreement or transaction that transfers, in whole or in part, the economic
consequence of ownership of the Common Stock, without the prior written consent
of J.P. Morgan Securities Inc., for a period of 180 days after the date of this
Prospectus. The foregoing does not prohibit the Company's issuance of shares
pursuant to the exercise of the Underwriters over-allotment option or under the
Incentive Plan, the 1992 Stock Plan, the Directors' Plan or the Purchase Plan.
J.P. Morgan Securities Inc. may, in its sole discretion at any time or from time
to time, without notice, release all or any portion of the shares subject to the
lock-up agreements.
    
 
The Underwriters have advised the Company that they do not expect that sales to
accounts over which they exercise discretionary authority will exceed 5% of the
shares offered hereby.

<PAGE>
Prior to this Offering, there has been no public market for the Common Stock.
The initial public offering price for the shares of Common Stock offered hereby
will be determined through negotiations among the Company and the Underwriters.
Among the factors to be considered in making such determination are the history
of and the prospects for the industry in which the Company operates, an
assessment of the Company's management, the present operations of the Company,
the historical results of operations of the Company, the prospects for future
earnings of the Company, the general conditions of the securities markets at the
time of the Offering and the prices of similar securities of generally
comparable companies.
 
There can be no assurance that an active trading market will develop for the
Common Stock or that the Common Stock will trade in the public market subsequent
to the Offering at or above the initial public offering price.
 
From time to time in the ordinary course of their respective businesses, the
Representatives and their respective affiliates may in the future provide
investment banking and other financial services to the Company and its
affiliates.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors
CV Therapeutics, Inc.
 
We have audited the accompanying consolidated balance sheets of CV Therapeutics,
Inc. (a development stage company) as of December 31, 1994 and 1995, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1995 and for
the period from inception (December 11, 1990) to December 31, 1995 (not
separately presented herein). 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 generally accepted auditing
standards. 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 consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of CV
Therapeutics, Inc. (a development stage company) at December 31, 1994 and 1995,
and the consolidated results of its operations and its cash flows for each of
the three years in the period ended December 31, 1995 and for the period from
inception (December 11, 1990) to December 31, 1995 (not separately presented
herein) in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   
(INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED)
    
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
THE COMPANY
 
CV Therapeutics, Inc. (the "Company"), a development stage biopharmaceutical
company, was incorporated in the State of Delaware on December 11, 1990 to focus
exclusively on the application of molecular cardiology to the discovery,
development and commercialization of novel, small molecule drugs for the
treatment of chronic cardiovascular diseases. The Company's primary activities
since incorporation have been establishing its offices and research facilities,
recruiting personnel, conducting research and development, performing business
and financial planning and raising capital.
 
   
Since inception, the Company has accumulated a deficit of approximately $43.6
million. Management expects to incur additional losses to complete product
development, and commercialization, as necessary, and recognizes the need to
raise additional funds from outside sources. In March and May 1996 the Company
successfully consummated an equity financing transaction which raised
approximately $13.0 million and has completed a refinancing of its existing debt
obligations (see Note 5). Management believes that it will be able to obtain
additional funds through either public or private equity or debt financings,
collaborative and other arrangements with corporate partners or from other
sources. If adequate funds are not available, the Company may be required to
reduce its level of spending, or eliminate one or more of its research and
development programs.
    
 
PRINCIPLES OF CONSOLIDATION
 
The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiary, CV Therapeutics International, which was
incorporated in December 1993 in the Cayman Islands. All significant
intercompany balances have been eliminated.
 
INTERIM FINANCIAL INFORMATION
 
   
The financial information at September 30, 1996 and for the nine months ended
September 30, 1995 and 1996 is unaudited but includes all adjustments
(consisting only of normal recurring adjustments) which the Company considers
necessary for a fair presentation of the financial position at such date and the
operating results and cash flows for those periods. Results for the nine months
ended September 30, 1996 are not necessarily indicative of results for the
entire year.
    
 
RESEARCH AND DEVELOPMENT
 
Research and development expenses consist of costs incurred for independent
research and development. These costs include direct and research-related
overhead expenses.
 
CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
The Company considers all highly liquid investments with a maturity from date of
purchase of three months or less to be cash equivalents. Cash equivalents
consist primarily of money market funds. All other liquid investments are
classified as short-term investments. Short-term investments in 1994 consist
primarily of auction market preferred stock, money market capital notes, and
bank notes. The Company limits its concentration of risk by diversifying its
investments among a variety of issuers.
 
   
Management determines the appropriate classification of investment securities at
the time of purchase and reevaluates such designation as of each balance sheet
date. At December 31, 1994 and 1995 and September 30, 1996, all investment
securities are designated as available-for-sale. Available-for-sale securities
are carried at fair value, with the unrealized gains and losses reported in
stockholders' equity. The amortized cost of debt securities in this category is
adjusted for amortization of premiums and accretion of discounts to maturity.
Such amortization is included in interest income.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
The cost of securities sold is based on the specific identification method.
Interest and dividends on securities classified as available-for-sale are
included in interest income.
 
Realized gains and losses and declines in value judged to be other than
temporary for available-for-sale securities are included in the statement of
operations. There have been no such transactions through December 31, 1995.
 
DEPRECIATION AND AMORTIZATION
 
Property and equipment are stated at cost, less accumulated depreciation and
amortization. Depreciation is provided using the straight-line method over the
estimated useful lives of the respective assets, generally three to five years.
Leasehold improvements are amortized over the lesser of the lease term or the
estimated useful lives of the related assets, generally two to three years.
Organization costs are amortized over a period of five years.
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.
 
NET LOSS PER SHARE
 
Except as noted below, historical net loss per share is computed using the
weighted average number of common shares outstanding. Common equivalent shares
are excluded from the computation as their effect is antidilutive, except that,
pursuant to the Securities and Exchange Commission ("SEC") Staff Accounting
Bulletins, common and common equivalent shares issued during the 12-month period
prior to the initial filing of the proposed offering at prices below the assumed
public offering price have been included in the calculation as if they were
outstanding for all periods presented (using the treasury stock method for stock
options at the estimated public offering price).
 
Historical net loss per share information is as follows:

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
STOCK-BASED COMPENSATION
 
In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"). SFAS 123 is effective for fiscal years beginning
after December 15, 1995. Under SFAS 123, stock-based compensation expense is
measured using either the intrinsic-value method as prescribed by Accounting
Principle Board Opinion No. 25 or the fair-value method described in SFAS 123.
The Company plans to implement SFAS 123 in 1996 using the intrinsic-value
method; accordingly, there will be no effect upon adopting SFAS 123 on the
Company's financial position or results of operations.
 
2.  LICENSE AND COLLABORATION AGREEMENTS
 
GENTA INCORPORATED
 
In January 1993, the Company, along with Genta Incorporated (collectively
referred to as "Licensees"), entered into a worldwide license agreement with the
Board of Trustees of the Leland Stanford Junior University ("Stanford"). Under
the terms of the agreement, Stanford granted the Licensees rights with respect
to certain patents to make, use and sell products for the treatment of coronary
restenosis and other vascular and associated human conditions. In consideration
for these patent rights, the Licensees paid a $100,000 licensing fee upon
signing the agreement. The Licensees provided for certain nonrefundable annual
royalties and nonrefundable milestone royalties over the term of the agreement,
and royalties on net sales of licensed products.
 
On June 28, 1996, the Company and Stanford agreed upon the terms pursuant to
which the January 1993 license agreement referred to above was terminated.
 
GENTA/GENTA JAGO TECHNOLOGIES B.V.
 
On April 9, 1993, the Company entered into a five-year research and development
collaboration with Genta, Incorporated ("Genta") and Genta Jago Technologies
B.V. ("GJT") to design, develop and commercialize certain products utilizing the
technology which is the subject of the Stanford license agreement described
above. The agreement obligated the Company, Genta and GJT to jointly fund
certain research costs.
 
In connection with this agreement, Genta acquired a warrant to purchase
1,000,000 shares of the Company's Series B preferred stock at $2.50 per share
(100,000 shares of common stock at $25.00 per share on an as-if converted
basis). The purchase price for the warrant was $0.48 per underlying share or
$480,000 (100,000 shares of common stock at $4.80 on an as-if converted basis).
The warrant is exercisable immediately and expires on April 7, 2003.
 
As stated above, in June 1996, the Company and Stanford agreed upon the terms
pursuant to which the license terminated and, consequently, there are no further
obligations to perform under this collaboration agreement. Although the
agreements with Genta and GJT have not been terminated, the Company believes
that neither party is currently pursuing the collaborative research.
 
UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.
 
In June 1994, the Company entered into a license agreement with the University
of Florida Research Foundation, Inc. ("UFRFI") under which the Company received
exclusive worldwide rights with respect to certain patents to develop adenosine
A(1) receptor antagonists and agonists for the detection, prevention and
treatment of human and animal diseases. In consideration for the license, the
Company paid UFRFI an initial license fee and is obligated to pay royalties
based on net sales of products which utilize the licensed technology.
 
Pursuant to the agreement, the Company must exercise commercially reasonable
efforts to develop and commercialize one or more products covered by the
licensed technology and is obligated to meet milestones in

completing certain preclinical work. In the event the Company fails to reach
those milestones, UFRFI may convert the exclusive license into a non-exclusive
license. As part of the license agreement with UFRFI, the Company entered into a
research agreement with the University of Florida.
 
SYNTEX (U.S.A.) INC.
 
In March 1996, the Company entered a license agreement with Syntex (U.S.A.) Inc.
("Syntex"), which is an indirect subsidiary of Roche Holding Limited, pursuant
to which the Company was granted an exclusive license in certain territories
under Syntex patents and know-how for the sale of products incorporating the
licensed technology, in exchange for an up front license fee, milestone payments
and royalties. In consideration for the up front license fee of $750,000, the
Company issued to Syntex 375,000 shares of Series E preferred stock and a five
year warrant to purchase 187,500 shares of Series E preferred stock at $2.00 per
share (18,750 shares of common stock at $20.00 per share on an as-if converted
method).
 
BAYER AG
 
On May 7, 1996, the Company entered a License Agreement with Bayer AG in the
area of inflammatory diseases. Pursuant to this agreement, the Company has
granted Bayer AG an exclusive worldwide license under the Company's patents and
know-how to research, develop and market products incorporating the licensed
technology. In exchange for the license, the Company received an up front
non-refundable license fee and is entitled to receive milestone payments and
royalties in the future.

5.  LONG-TERM DEBT (CONTINUED)
The indebtedness to banks is secured by interests in equipment, furniture and
fixtures.
 
   
The carrying value of the corporate term loan approximates fair value at
December 31, 1995 and September 30, 1996. The fair value of the corporate term
loan was estimated using discounted cash flow analysis, based on the incremental
borrowing rates currently available to the Company for borrowings with similar
terms and maturity.
    
 
   
On September 27, 1996, the Company completed a refinancing of its existing debt
obligations with $5.0 million of debt financing from entities associated with
Hambrecht & Quist Group. (the H&Q Debt Financings). The H&Q Debt Financings
consist of a $3.0 million term loan which bears interest at the rate of 9.0% per
annum, secured by all of the assets of the Company, and has a final maturity in
September 1999, and a $2.0 million term loan which bears interest at 9.0% per
annum due January 1, 1997. The Company has the option on or before December 31,
1996 to convert the $2.0 million term loan to an equipment lease which would
bear interest at the rate of 9.0% per annum and would have a final maturity in

the fair value of the stock subject to the option on the date the option is
granted. All options are to have a term not greater than 10 years from the date

a five-year period, unless otherwise approved by the board of directors.
 
1994 EQUITY INCENTIVE PLAN

option shall be not less than 100% of the fair value of the stock subject to the
option on the date the option is granted. The exercise price of each
nonstatutory option shall be not less than 85% of the fair value of the stock
subject to the option on the date the option is granted. The vesting provisions
of individual options may vary but in each case will provide for vesting of at
least 20% of the total number of shares subject to the option per year.
 
NON-EMPLOYEE DIRECTOR'S STOCK OPTION PLAN
 
In September 1994, the Company's board of directors adopted the Non-Employee
Director's Stock Option Plan. Under the Plan, options for up to 20,000 shares of

grant. The exercise price of each option shall be the fair value of the stock
subject to such option on the date such option is granted. The options generally
vest in increments over a period of three years from the date of grant.
 
Outside of Stock Option Plans, from May 1993 through June 1995 the Company
granted options to purchase 85,500 shares of Common Stock to employees and
consultants. The exercise prices ranged from $0.80 to $2.50 per share, which
exercise prices represent the fair value of common stock at the respective grant
dates. The stock option terms vary between the individual grants and were
approved by the board of directors.

basis). This warrant is exercisable immediately and expires at the earlier of
September 8, 1997 or an initial public offering in excess of $7,500,000 at an
offering price of not less than $5.00 per share as adjusted for any stock
dividends, stock split, recapitalization or consolidation of the Company's
common stock. As of December 31, 1995, 25,000 shares of common stock have been
reserved for the exercise of this warrant.
 
In connection with the equipment lease entered into in 1993, the Company issued
a warrant to purchase 2,812 shares of the Company's common stock at $8.00 per
share. This warrant is exercisable immediately and expires at the earlier of
March 18, 1999 or an initial public offering in excess of $7,500,000 or a merger
or consolidation of the Company with or into another corporation or entity. As
of December 31, 1995, 2,812 shares of the Company's common stock have been
reserved for the exercise of the warrant.
 
   
In connection with the 1993 facility lease, the Company issued warrants to
purchase 30,000 shares of the Company's Series C preferred stock at $1.25 per
share (3,000 shares of common stock at $12.50 per share on an as-if-converted
basis). The warrants expired in August 1996.
    
 
   
In connection with the sale of Series D preferred stock, the Company issued
warrants to purchase 219,266 shares of the Company's Series D preferred stock at

In connection with the corporate term loan obtained in April 1995, the Company
issued warrants to purchase 400,000 shares of the Company's Series D preferred
stock at $2.50 per share (40,000 shares of common stock at $25.00 per share on

April 24, 2005. As of December 31, 1995, 40,000 shares of common stock have been
reserved for the exercise of the warrant. In June 1996, the warrant agreement
was amended to change the exercise price of the warrants from $25.00 per share
to $8.90 per share, in exchange for the elimination of certain loan covenants.
This change in terms resulted in a new measurement date for the warrants for
accounting purposes, and, therefore, a value of $160,000 has been recorded in
June 1996 based on the deemed fair value of the warrants at that date. The
warrant value was initially amortized over the remaining life of the loan.
However, on September 30, 1996, the Company repaid the remaining balance of the
loan and expensed the unamortized portion of the warrant value at that date. The
warrants are exercisable immediately and expire on March 23, 1999. As of

exercise of the warrants.

the earlier of September 7, 2000, an initial public offering of common stock at
an offering price of not less than $5.00 per share as adjusted for any stock
dividends, combinations or stock split with respect to such stock or a merger,
reorganization or sale of substantially all of the assets of the Company. As of

of common stock at $20.00 per share on an as-if-converted basis). The warrant
was issued in lieu of payment for legal services rendered totaling $48,750 and
is separately disclosed in the statement of stockholders' equity. The warrant is
exercisable immediately and expires at the earlier of December 2000 or upon the
consummation of a qualified initial public offering, as defined in the related

an exercise price of $20.00 per share, and five year warrants to purchase 84,500

9.  INCOME TAXES
As of December 31, 1995, the Company had federal net operating loss
carryforwards of approximately $32,000,000. The Company also had research and
development tax credit carryforwards of approximately $1,200,000. The difference
between the federal net operating loss carryforwards and the accumulated deficit
relates to losses generated by the Company's wholly owned subsidiary, CV
Therapeutics, International. The net operating loss and credit carryforwards
will expire at various dates beginning on 2007 through 2010, if not utilized.
 
Utilization of the net operating losses and credits may be subject to an 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 credits before utilization.
 
Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
and the amount used for income tax purposes. Significant components of the
Company's deferred tax assets as of December 31 are as follows:

10. SUBSEQUENT EVENTS
In September 1996, the board of directors authorized management of the Company
to file a registration statement with the SEC permitting the Company to sell
shares of its common stock to the public. If the initial public offering is
closed under the terms presently anticipated, all of the preferred stock
outstanding will automatically convert into 3,238,185 shares of common stock.
Unaudited pro forma stockholders' equity, as adjusted for the assumed conversion
of the preferred stock, is set forth on the balance sheet.
 
   
Also in September 1996, the board of directors of the Company authorized a
1-for-10 reverse stock split, in which ten shares of common stock were exchanged
for one share of common stock. Following stockholder approval, the stock split
is expected to be effected in October 1996. Effective upon the closing of the

ITEM 14  INDEMNIFICATION OF DIRECTORS AND OFFICERS
    
 
The Registrant's Restated Certificate of Incorporation provides that directors
of the Registrant shall not be personally liable to the Registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director, to
the fullest extent permitted by the General Corporation Law of the State of
Delaware. The Registrant's Restated Bylaws provide for indemnification of
officers and directors to the full extent and in the manner permitted by
Delaware law. Section 145 of the Delaware General Corporation Law makes
provision for such indemnification in terms sufficiently broad to cover officers
and directors under certain circumstances for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act").
 
The Registrant has entered into indemnification agreements with each officer and
director which provide indemnification under certain circumstances for acts and
omissions which may not be covered by any directors' and officers' liability
insurance.
 
The form of Underwriting Agreement, to filed as Exhibit 1.1 to the Registration
Statement, provides for indemnification of the Registrant and its controlling
persons against certain liabilities under the Securities Act.

ITEM 17.  UNDERTAKINGS.
 
A.  The Registrant hereby undertakes to provide to 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.
 
B.  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 14 above, 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 Securities 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, 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 of whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

C.  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 part of this
    registration statement as of the time it was declared effective.
 
    (2)  For purposes 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.

In connection with this opinion, we have (i) examined and relied upon the

of Incorporation, as set forth in Exhibit 3.4 of the Registration Statement, 
shall have been duly approved and filed with the office of the Delaware

                Agreement No.  9609        Dated as of September 27, 1996
                             -----

Lessor:       Hambrecht & Quist Guaranty Finance, LLC

Address:      One Bush Street
              San Francisco, CA 94104


Lessee:       CV Therapeutics, Inc.

Address:      3172 Porter Drive
              Palo Alto, CA 94304


    This contract is a MASTER LEASE AGREEMENT of fixtures, furniture,
equipment, and leasehold improvements made to real property which is leased to
Lessee under a FACILITY LEASE as described herein, and other personal property
(individually and collectively called "EQUIPMENT" or "PROPERTY"), described in
any schedule now or hereafter attached hereto described as "EQUIPMENT SCHEDULE
No. 1" (each an "EQUIPMENT SCHEDULE" and collectively "EQUIPMENT SCHEDULES").
The FACILITY LEASE is a commercial lease between Lessee, as Tenant, and Matadero
Creek, as Landlord, dated August 6, 1993, as amended on June 30, 1994.
Each EQUIPMENT SCHEDULE shall incorporate therein all of the terms
and conditions of this and any attachments, modifications, exhibits or
amendments executed by Lessee and Lessor ("LEASE").  In the event of a conflict
between this MASTER LEASE AGREEMENT and any EQUIPMENT SCHEDULE or attachment,
modification or amendment to any EQUIPMENT SCHEDULE the latter shall prevail;
however, no EQUIPMENT SCHEDULE shall have any effect or modification on any
other EQUIPMENT SCHEDULE except as expressly provided herein.  Any EQUIPMENT
SCHEDULE covered hereunder is subject to approval by Lessor and shall be
effective only upon written communication of acceptance from Lessor to Lessee.

    For the purposes of this Master Lease Agreement, the term Related Documents
means and includes without limitation this Master Lease Agreement and the
Equipment Schedule, and (a) agreements between Lessor and Lessee all dated as of
September 27, 1996 including but not limited to: the Security Agreement
between Lessor, as Secured Party, and Lessee, as Debtor; the Financing Agreement
between Lessor, as Secured Party, and Lessee, as Debtor; and the Business Loan
Agreement between Lessor, as Lender, and Lessee, as Borrower; and (b) agreements
between Hambrecht & Quist Transition Capital, LLC ("H&QTC") and Lessee all dated
as of September 27, 1996 including but not limited to: the Business Loan
Agreement between H&QTC as Secured Party and Lessee, as Debtor, the Security
Agreement between H&QTC, as Secured Party, and Lessee, as Debtor.

    For the purposes of this Master Lease Agreement, the term Collateral shall
have that meaning as defined in the Security Agreement between Lessor, as
Debtor, and Lessee, as Secured Party.

    Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor, the
PROPERTY described in the EQUIPMENT SCHEDULE(s) in accordance with the preceding
paragraph and the parties mutually agree as follows:

    1.   SELECTION; WARRANTY AND DISCLAIMER OF WARRANTIES BY LESSOR. LESSOR IS
NOT THE CONTRACTOR, MANUFACTURER OR VENDOR OF


                            Master Equipment Lease, Page 1


<PAGE>

PROPERTY.  LESSEE HAS SELECTED THE PROPERTY.  LESSOR MAKES NO WARRANTY,
EXPRESSED OR IMPLIED, AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITION OF
PROPERTY,  ITS MERCHANTABILITY OR ITS FITNESS FOR ANY PARTICULAR PURPOSE, AND,
AS TO LESSOR, LESSEE LEASES PROPERTY "AS IS".  LESSEE ACKNOWLEDGES THAT THIS
LEASE IS INTENDED TO QUALIFY AS A "FINANCE LEASE" UNDER THE CALIFORNIA UNIFORM
COMMERCIAL CODE ("CUCC").

    2.   CLAIMS AGAINST VENDOR.  If PROPERTY is not properly installed, does
not operate as represented or warranted by the contractor, manufacturer, or
vendor ("Vendor"), or is unsatisfactory for any reason, Lessee shall make any
claim on account thereof solely against Vendor and shall, nevertheless, pay
Lessor all rent payable under this LEASE.  Lessor hereby agrees to assign to
Lessee, solely for the purpose of making and prosecuting any said claim, all of
the rights which Lessor has against Vendor for breach of warranty or other
representation respecting PROPERTY.

    3.   VENDOR NOT AN AGENT.  Lessee understands and agrees that neither
Vendor, nor any sales representative or other agent of Vendor, is an agent of
Lessor.  No sales representative or agent of Vendor is authorized to waive or
alter any term or condition of this LEASE, and no representation as to PROPERTY
or any other matter by Vendor shall in any way affect Lessee's duty to pay the
rent and perform its other obligations as set forth in this LEASE.

    4.   NON-CANCELABLE LEASE; LESSEE'S OBLIGATIONS ABSOLUTE; LESSOR
OBLIGATIONS AND TERMINATION RIGHTS. This LEASE cannot be canceled or terminated
except as expressly provided herein.  Lessee's obligation to pay all amounts due
under each LEASE shall be absolute and unconditional and shall not be subject to
any delay, reduction, set-off, defense, counterclaim or recoupment for any
reason whatsoever. To the extent permitted by applicable law,  Lessee
specifically waives its rights and remedies under Section 10508 through 10522 of
the CUCC, including (without limitation) Lessee's rights to (i) cancel or
repudiate this Lease, (ii) reject or revoke acceptance of the leased property,
(iii) recover damages from the Lessor for breach of warranty or for any other
reason under such CUCC sections, (iv) claim a security interest in any rejected
property in Lessee's possession of control, (v) deduct from rental payments all
or any part of any claimed damages resulting from Lessor's default under this
Lease, (vi) accept partial delivery of the Property, and (vii) "cover" by making
any purchase or lease of other property in substitution from property due from
Lessor, (viii) recover from the Lessor any general, special, incidental or
consequential damages, for any reason whatsoever other than Lessor's breach of
this Agreement, and (ix) specific performance, replevin or the like for any of
the Property.

    5.   EQUIPMENT LEASE.  The following terms and conditions shall apply to
the lease of Equipment.

    5(a).     TERM.  This LEASE commences  on October 1, 1996  (the
"COMMENCEMENT DATE"), notwithstanding that rent payments shall commence as
provided in Paragraph 5(b) below, and shall continue until all Lessee's
obligations are fulfilled hereunder, unless sooner terminated as provided herein
as to all or any part of the PROPERTY.  The INITIAL TERM of any EQUIPMENT
SCHEDULE begins on the COMMENCEMENT DATE and expires on the day immediately
preceding the third (3rd) anniversary of the COMMENCEMENT DATE.

    In the absence of any written agreement to the contrary, each EQUIPMENT
SCHEDULE shall be dependent on any and all other EQUIPMENT SCHEDULES now or
hereafter executed by the parties hereto with respect to any purchase or renewal
as provided in Paragraph 5(c) hereof.

    5(b).     RENT. Lessee shall pay the rent payments as shown on the
EQUIPMENT SCHEDULE and as may be adjusted by the rider to the Equipment Schedule
the first of which rent


                            Master Equipment Lease, Page 2


<PAGE>

payments shall be due on the COMMENCEMENT DATE specified therein, unless the
Lessee qualifies for deferred payments as herein described.  The Lessee shall
qualify to defer the first eighteen (18) months of rent payments until the first
day of the nineteenth month, on which date the nineteenth (19th) rent payment
will also be due, unless (a) after September 1, 1996 Lessee sells shares of its
stock (or options or other rights to acquire such shares) with gross proceeds of
at least Thirteen Million Dollars ($13,000,000) prior to the end of the
deferment period, or (b) there is an occurrence of any EVENT OF DEFAULT under
Paragraph 17.  In the event that Lessee fails to qualify for deferred payments
prior to the date that the nineteenth (19th) rent payment is due, all deferred
payments will be due within ten (10) days of such failure to qualify, except in
the case of an Event of Default, in which case all deferred payments will be
immediately due.  Subsequent payments shall be due on the same day of each month
(or other calendar period indicated on the EQUIPMENT SCHEDULE) thereafter.  Rent
payments shall be due whether or not Lessee has received any notice that such
payments are due.  All rent payments shall be paid to Lessor at its address set
forth on the EQUIPMENT SCHEDULE or as otherwise directed by Lessor in writing.

    5(c).     PURCHASE AND RENEWAL.  If no default shall have occurred and is
continuing hereunder or under any EQUIPMENT SCHEDULE or under the Related
Documents, and provided that all lease payments due, and all lease payments that
would have been due notwithstanding any deferral as provided in paragraph 5(b)
above, have been paid in full, Lessee shall have the option, exercisable at any
time, to elect to purchase all of the PROPERTY under each and every EQUIPMENT
SCHEDULE to this LEASE (but not less than all the EQUIPMENT SCHEDULES to this
LEASE), for the Lessor's purchase cost less sixty percent (60%) of all rents
paid to that date for such EQUIPMENT SCHEDULE.  In the event that the purchase
option is not exercised, Lessee may give Lessor six months written notice of its
intention to terminate all of the EQUIPMENT SCHEDULES to this LEASE.  Should
Lessee fail to give notice to Lessor six months prior to the end of the INITIAL
TERM of the EQUIPMENT SCHEDULE,  the LEASE TERM shall be extended, until Lessee
gives such six months notice to terminate the EQUIPMENT SCHEDULE.  In the event
an EQUIPMENT SCHEDULE is extended, Lessee shall continue to pay Lessor rent at
the rate of 40% of the EQUIPMENT RENT as provided in Paragraph 5(b) above.

    6.   LOCATION; INSPECTION; LABELS.  PROPERTY shall be delivered to and
shall not be removed from the "Property Location" shown on the EQUIPMENT
SCHEDULE, without Lessor's prior written consent, which consent shall not be
unreasonably withheld for PROPERTY loaned to others in the ordinary course of
Lessee's business for which Lessee has provided Lessor a description of such
PROPERTY and the address where it is to be temporarily located.  Lessor shall
have the right to inspect PROPERTY with reasonable notice during regular
business hours.  If Lessor supplies Lessee with labels stating that PROPERTY is
owned by Lessor, Lessee shall affix such labels to and keep them in a prominent
place on PROPERTY.

    7.   REPAIRS; USE; ALTERATIONS.  Lessee at its own cost and expense, shall
keep PROPERTY in good repair, condition and working order; shall use equipment
lawfully; and shall not alter PROPERTY without Lessor's prior written consent.
Unless a default shall have occurred and is continuing under any of the Related
Documents, Lessee shall have the right to quietly possess, enjoy and use the
PROPERTY without interference by Lessor, its assigns, or anyone claiming
through  or under Lessor.

    8.   SURRENDER.  Upon the expiration of the INITIAL TERM of any EQUIPMENT
SCHEDULE, or any renewal TERM not automatically extended pursuant to Section
5(c) above, or upon demand by Lessor made pursuant to the terms of this LEASE,
Lessee, at its expense, shall return the EQUIPMENT by delivering it to such
place or on board such carrier, packed for shipping, within the continental
United States,  as Lessor may specify.  Lessee agrees that the PROPERTY, when
returned, shall be in the same condition as when delivered to Lessee, reasonable
wear and tear excepted, and if available for PROPERTY of like kind and age, in a
condition which will permit Lessor to be eligible for manufacturer's standard
maintenance contract without incurring any


                            Master Equipment Lease, Page 3


<PAGE>

expense to repair or rehabilitate such PROPERTY (Lessee shall be liable for
reasonable and necessary expenses to place PROPERTY in such condition).  Lessee
shall give Lessor six months written notice that it is returning the PROPERTY as
provided above.

    9.   LOSS OR DAMAGE.  Lessee shall bear the entire risk of loss, theft,
destruction of or damage to PROPERTY or any item thereof (herein "Loss or
Damage") from any cause whatsoever.  No Loss or Damage shall relieve Lessee of
the obligation to pay rent or of any other obligation under this LEASE, provided
all applicable insurance payments received by Lessor pursuant to paragraph 10
below are applied to such repair or replacement, or as mutually agreed between
Lessor and Lessee.  In the event of Loss or Damage, Lessee, at the option of
Lessor, shall (a) place the same in good condition and repair; or (b) replace
the same with like property in good condition and repair with clear title
thereto in Lessor.

    10.  INSURANCE. The Lessee at all times will maintain, with insurance
companies acceptable to Lessor and licensed and qualified to do business in the
jurisdiction in which Lessee's operations are conducted, insurance on all
property owned by it, in such amounts (including, without limitation, so-called
"all-risk" coverage at replacement value and "broad form" liability coverage),
against such hazards and liabilities and for such purposes as the Lessor shall
determine is reasonable to insure the value of the Collateral and as is
customary in the industry for companies of established reputation engaged in the
same or similar businesses and owning or operating similar properties.  Without
limiting the generality of the foregoing, Lessee shall initially maintain
Commercial General Liability Insurance covering Lessee and naming Lessor as
additional insured, for claims of bodily injury, and property damage arising out
of Lessee's operations, assumed liabilities or use of any of the real property
leased or owned by Lessee, for limits of liability not less than:  (a)  Bodily
Injury and Property: $3,000,000 each occurrence; (b)  Damage Liability:
$3,000,000 annual aggregate.  In addition, the Lessee shall maintain all
insurance required of the tenant by the landlord of any of the real estate
leased by the Company and shall maintain adequate business interruption
insurance to assure in addition to customary risks that Lessee is able to pay
the rent and all other charges due under its leases notwithstanding a business
interruption.  The Lessor shall be named as loss payee with respect to property
damage insurance  for PROPERTY, and additional loss payee and additional insured
for property damage to all other Collateral and all other insurance coverage as
described herein and shall be given 30 days' advance notice of any amendment to
or cancellation of insurance.  No settlement on account of any loss covered by
such insurance shall be effected without the consent of the Lessor.  Upon
request of the Lessor from time to time, and in any event on the Commencement
Date of the first Equipment Schedule attached to this Master Lease Agreement and
thereafter fifteen (15) days prior to the expiration date of any policy of
insurance required hereunder, the Lessee shall furnish to the Lessor
certificates or other evidence satisfactory to the Lessor of compliance with the
foregoing insurance provisions.  If the Lessee fails to provide or cause to be
provided such insurance, the Lessor in its sole discretion, may provide such
insurance and charge the cost to the Lessee and the Lessee shall promptly pay
the cost thereof to the Lessor.  Any payment not recovered from the Lessee shall
bear interest at an annual rate of twelve percent.  The Lessor shall not, by the
fact of approving, disapproving, accepting, obtaining or failing to obtain any
such insurance, incur any liability for the form or legal sufficiency of
insurance contracts, solvency of insurance companies or payment of lawsuits, and
the Lessee hereby expressly assumes full responsibility therefor and liability,
if any, thereunder.

    11.  TAXES; LIENS.  Lessee shall reimburse to Lessor (or pay directly if
instructed by Lessor) and shall hold Lessor harmless on an after-tax basis from
all charges and taxes, together with any penalties or interest thereon or other
additions thereto, which may now or hereafter be imposed or levied by any
federal, state or local taxing authority in the United States upon the sale,
purchase, ownership, leasing, possession or use of the PROPERTY or upon any rent
payable hereunder, or otherwise in connection with the transactions contemplated
by this agreement, excluding, however, all taxes on or measured by Lessor's net
income.  At (a) the end of any renewal term or (b) if the Initial Term is not
extended, at the end of the Initial Term, (c) or upon


                            Master Equipment Lease, Page 4


<PAGE>

request by Lessor, Lessee shall deposit with Lessor an amount that Lessor
reasonably estimates may be due for property taxes on the PROPERTY.

    12.  LESSOR'S PAYMENT; LIENS.  If Lessee fails to provide or maintain said
insurance, to pay said taxes, charges and fees, or to discharge any levies,
liens, and encumbrances made, caused, allowed or suffered by Lessee, Lessor
shall have the right, but shall not be obligated, to obtain such insurance, pay
such taxes, charges and fees, or effect such discharge.  In that event,  Lessee
shall repay to Lessor the cost thereof with the next rent payment.  Lessee shall
keep or cause PROPERTY to be kept free and clear of all levies, liens and
encumbrances.

    13.  FACILITY LEASE.  Lessee shall make all payments when due to the
landlord under the Facility Lease, and perform all of its obligations under the
Facility Lease.  If Lessee fails to make any payments when due under the
Facility Lease, Lessor shall have the right, but shall not be obligated, to pay
such rent, charges and fees, or effect such discharge.  In that event,  Lessee
shall repay to Lessor the cost thereof immediately upon demand by Lessor.
Lessee shall give Lessor notice within ten days of when any officer of Lessee
becomes aware of any default by landlord under any of its obligations under the
Facility Lease.

    14.  GENERAL INDEMNITY.  Lessee shall indemnify Lessor against and hold
Lessor harmless from any and all claims, actions, damages, including reasonable
attorneys' fees, obligations, liabilities and liens (including any of the
foregoing arising or imposed under the doctrine of "strict liability in tort or
product liability"), arising out of the manufacture, purchase, lease,
possession, operation, condition, return or use of PROPERTY or by operation of
law, excluding however, any of the foregoing resulting from culpable negligence
or willful misconduct of Lessor.  Lessee agrees that upon written notice by
Lessor of the assertion of such a claim, action, damage, obligation, liability
or lien, Lessee shall assume full responsibility for the defense thereof.

    15.  ASSIGNMENT; OFFSET.  (a) Without Lessor's prior written consent,
Lessee shall not assign, transfer, or otherwise dispose of this Lease, Property,
or any interest therein, or sublet or lend Property or permit it to be used by
anyone other than Lessee or Lessee's employees.  Lessor shall reasonably consent
to the sublet of property under the sub-lease agreement under the Facility
Lease, provided that Lessor has been provided a copy of the sub-lease agreement.
To the extent that any such assignment or transfer constitutes the grant of a
security interest, this Paragraph 15(a) shall be enforceable to the extent
permitted by law.

         (b)  Lessor may assign or sell this LEASE, any of its rights
hereunder, or grant a security interest in any PROPERTY in whole or in part with
or without notice to Lessee.  Lessee acknowledges that any such assignment by
Lessor shall not materially impair the prospect of obtaining return performance
by Lessor,  materially change Lessee's duties or obligations under this LEASE,
nor materially increase the burden or risk imposed on Lessee and Lessee agrees
that any such assignment or transfer shall be permitted provided such assignment
does not materially affect the interests of Lessee.  If Lessee is given notice
of such assignment or sale, it agrees to acknowledge receipt thereof in writing.

    16.  DELINQUENT PAYMENTS.  (a) Service Charge.  Since it would be
impractical or extremely difficult to fix Lessor's actual damages for collecting
and accounting for a late payment, if any payment to Lessor required herein is
not paid on or before its due date, Lessee shall pay to Lessor an amount equal
to five percent of any such late payment (but not less than $10 nor more than
$250).  (b) Interest.  Lessee shall also pay interest on any such late payment
from the due date thereof until the date paid  at the lesser of 14% per annum or
the maximum rate allowed by law.


                            Master Equipment Lease, Page 5


<PAGE>

    17.  EVENTS OF DEFAULT.  Any of the following shall constitute an EVENT OF
DEFAULT under the LEASE:

    (a)  Lessee fails to pay when due any rent or other amount required herein
to be paid by Lessee, and such nonpayment continues for a period of ten days
after written notice thereof from Lessor;

    (b)  Lessee ceases doing business as a going concern, is insolvent, makes
an assignment for the benefit of creditors, admits in writing its inability to
pay its debts as they become due, files a voluntary petition in bankruptcy, is
subject to an involuntary petition in bankruptcy, is adjudicated bankrupt or
insolvent, makes a bulk transfer of furniture, furnishings, fixtures or other
equipment or inventory, files or has filed against it a petition seeking any
reorganization, arrangement or composition, under any present or future statute,
law or regulation;

    (c)  Lessee fails to perform or observe any other term, covenant or
condition of this LEASE or any other document, agreement or instrument executed
pursuant hereto or in connection herewith which is not cured within ten days
after written notice thereof from Lessor;

    (d)  Any of Lessee's representations or warranties made herein or on any
statement or certificate at any time given in writing pursuant hereto or in
connection herewith shall prove false or misleading in any material respect when
made;

    (e)  Lessee defaults under any of the Related Documents.

    (f)  Lessee defaults under or otherwise has accelerated any obligation,
credit agreement, loan agreement, conditional sales contract, lease, indenture
or debenture, except such as may in good faith be contested or disputed or for
which arrangements for deferred payments have been made for a cumulative  amount
less than $125,000; or Lessee defaults under any other agreement or EQUIPMENT
SCHEDULE now existing or hereafter made with Lessor or with any of Lessor's
commonly owned affiliates.

    (g)  Lessee defaults under or otherwise has accelerated the Facility Lease,
or the Facility Lease is otherwise terminated.

    18.  REMEDIES.  If an EVENT OF DEFAULT occurs and is continuing, Lessor
shall have the right, with or without notice or demand upon Lessee, to pursue
and enforce, successively and/or concurrently, any one or more of the following
remedies in order to protect the interests and reasonably expected profits and
bargains of Lessor:

    (a)  Lessor may terminate this LEASE and/or any EQUIPMENT SCHEDULE with
respect to all or any part of the PROPERTY;

    (b)  With or without retaking the PROPERTY Lessor may (1) recover from
Lessee all accrued and unpaid rents and other amounts then due and owing under
the terms hereof, (2) recover from Lessee from time to time all rents and other
amounts as and when becoming due hereunder, (3) accelerate and cause to become
immediately due and payable all rents and other amounts due and/or would become
due hereunder and recover from Lessee the present value to Lessor of such
amounts;  which "present value" for purposes of this Agreement shall be
calculated by discounting the amounts due at a rate equal to nine percent
(9.00%), to the earlier of the following dates: 1)  the date Lessor has obtained
possession of the PROPERTY, 2) the date Lessee has made an effective tender of
possession of the PROPERTY back to Lessor, or 3) if Lessee retains the PROPERTY,
to the date of payment of such amounts.


                            Master Equipment Lease, Page 6


<PAGE>

    (c)  Lessor may take possession of the PROPERTY (by Lessor, independent
contractor or by requiring Lessee to assemble and surrender the PROPERTY in
accordance with the provisions of Paragraph 9 hereof) without demand or notice,
without any court order or other process of law and without liability to Lessee
for any damages occasioned by such taking of possession and any such taking of
possession shall not constitute a termination of this LEASE and (1) terminate
the lease term as to the PROPERTY, (2) recover from Lessee all accrued and
unpaid rents and other amounts owing under the terms hereof, (3) sell the
PROPERTY at public or private sale, and recover from Lessee the difference, if
any, by which the net proceeds of sale shall be less than the present value of
Lessor's total reasonably anticipated profits with respect to the PROPERTY,  (4)
re-lease the PROPERTY to a third party for the account of Lessee and recover
from Lessee when becoming due any deficiency between the rents provided herein
and those received from such third party, (5)  re-lease the PROPERTY to a third
party for the account of Lessee and recover from Lessee the present value of
Lessor for any deficiency between the rents provided herein and those receivable
from such third party over the re-lease term, (6) recover from Lessee the
present value of Lessor of the excess of the rents reserved herein for the
balance of the INITIAL TERM (or any remaining term not covered by any re-lease
pursuant to Paragraph 18(c)(5) hereinabove) over the then-reasonable rental
value of the PROPERTY; and

    (d)  Upon request of Lessor, Lessee shall use reasonable commercial efforts
to effect an assignment of its interest in the FACILITY LEASE to Lessor to the
extent permitted thereunder and leave the premises under the FACILITY LEASE
peaceably and surrender possession to Lessor in accordance with the provisions

to the confidentiality provisions hereof.  Borrower additionally waives any and
all notices of sale of participation interest, as well as all notices of any

unless such waiver is given in writing and signed by Lender.  No delay or
omission on the part of Lender in exercising any right shall operate as a waiver
of such right or any other right.  A waiver by Lender of a provision of this
Agreement shall not prejudice or constitute a waiver of Lender's right otherwise
to demand strict compliance with that provision or any other provision of this
Agreement.  No prior  waiver by Lender, nor any course of dealing between Lender
and Borrower, shall constitute a waiver of any of Lender's rights or of any
obligations of Borrower as to any future transactions.  Whenever the consent of
Lender is required under this Agreement, the granting of such consent by Lender
in any instance shall not constitute continuing consent in subsequent instances
where such consent is required and in all cases such consent may be granted or
withheld in the sole discretion of Lender.

     SECTION 10.10  CONFIDENTIALITY.
In handling any confidential information Lender shall exercise the same degree
of care that it exercises with respect to its own proprietary information of the

received or received pursuant to this agreement except that disclosure of such
information may be made (i) to the subsidiaries or affiliates of Lender in
connection with their preset or prospective business relations with Borrower,

         by its nature be cured within the ten (10) day period and cannot after
         diligent attempts by Borrower be cured within such ten (10) day
         period; and such default is likely to be cured within a reasonable
         time, then Borrower shall have an additional reasonable period (which
         shall not in any case exceed thirty (30) days) to attempt to cure such
         default, and within such reasonable time period the failure to have
         cured such default shall not be deemed an Event of Default; or

              (d) Borrower shall be in default under any agreement with Senior
         Lender, provided however that if any default under any agreement with
         Senior Lender shall be cured or waived, it shall be automatically

         appointment of a custodian, receiver, trustee, or similar officer for
         it or for all or any substantial part of its property; or such
         custodian, receiver, trustee, or similar officer shall be appointed
         without the application or consent of Borrower and such appointment
         shall continue undischarged for a period of sixty (60) days; or

         or otherwise) any bankruptcy, insolvency, reorganization, moratorium,

         proceeding relating to it under the laws of any jurisdiction; or any
         such proceeding shall be instituted (by petition, application, or
         otherwise) against Borrower and shall remain undismissed for a period

         writ, or similar process shall not be released, vacated, or fully
         bonded within sixty (60) days after its issue or levy; or

              (f)  This Agreement or any of the Related Documents ceases to be
         in full force and effect (including failure of any collateral document
         to create a valid and perfected security interest or lien at any time
         and for any reason); or

              (g)  Commencement of foreclosure, whether by judicial proceeding,

         Borrower against any Collateral, or any creditor takes, attempts to
         take or gives written or oral notice to Borrower of its intent to take
         any action against the property of Borrower or any of its subsidiaries
         on or in which Lender has a lien or security interest.  This includes
         a garnishment, attachment, or levy on or of any of Borrower's deposit
         accounts.  However, this Event of Default shall not apply if there is
         a good faith dispute by Borrower or any of its subsidiaries as to the
         validity or reasonableness of the claim which is the basis of the
         creditor proceeding, and if Borrower gives Lender written notice of
         the creditor proceeding and furnishes reserves or a surety bond for
         the creditor proceeding satisfactory to Lender; or

              (h)  Any REPORTABLE EVENT, which Lender determines in good faith
         constitutes grounds for the termination of any PLAN or PLANS by the
         Pension Benefit Guaranty Corporation or for the appointment by the
         appropriate United States District Court of a trustee to administer or
         liquidate any PLAN or PLANS shall have occurred and be continuing
         thirty (30) days after written notice of such determination by Lender
         shall have been given to Borrower, or a decision shall have been made
         by Borrower or any Subsidiary to terminate, file a notice of
         termination with respect to, or withdraw from, any PLAN or PLANS, or a
         trustee shall be appointed by the appropriate United States District
         Court to administer any PLAN or PLANS, or the Pension Benefit Guaranty
         Corporation shall institute proceedings to terminate any PLAN or PLANS
         or to appoint a trustee to administer any PLAN or PLANS, and in the
         case of the occurrence of any of the above, the aggregate amount of
         Borrower's liability to the Pension Benefit Guaranty Corporation under
         Sections 4062, 4063, and 4064 of ERISA as determined in good faith by
         Lender could exceed 10% of Borrower's Consolidated Tangible Net Worth,
         and such liability of Borrower is not covered in full, for the benefit
         of Borrower, by insurance;

THEN, automatically, at the option of Lender, Lender's obligation to take any
action hereunder for Borrower's benefit shall terminate and all LOAN OBLIGATIONS
shall, without presentment, demand, protect, or notice of any kind, all of which
are hereby expressly waived, be forthwith due and payable, and Lender may,
immediately and without expiration of any period of grace, enforce payment of
all LOAN OBLIGATIONS and exercise any and all other

    SECTION 10.1  AMENDMENTS.
This Agreement, together with any Related Documents, constitutes the entire
understanding and agreement of the parties as to the matters set forth in this
Agreement.  No alteration of or amendment to this Agreement shall be effective

Borrower and Lender each hereby waives, to the fullest extent permitted by
applicable law, any right it may have to a trial by jury in respect of any
litigation directly or indirectly arising out of, under or in connection with

and Lender hereby (a) certify that no representative, agent or attorney of the
other party hereto has represented, expressly or otherwise, that such other
party would not, in the event of litigation, seek to enforce the foregoing
waiver and (b) acknowledges that it and the other party hereto have been induced
to enter to this Agreement by, among other things, the mutual waivers and
certifications contained in this Section 10.3.

    SECTION 10.4  CAPTION HEADINGS.
Caption headings in this Agreement are for convenience purposes only and are not
to be used to interpret or define the provisions of this Agreement.

    SECTION 10.5  CONSENT TO LOAN PARTICIPATION.

later, of one or more participation interest in the Loans to one or more
purchasers, whether related or unrelated to Lender.  Lender may provide, without

purchasers, any information or knowledge Lender may have about Borrower or about
any other matter relating to the Loan, and Borrower hereby waives any rights to
privacy it may have with respect to such matters; provided such purchasers agree


- --------------------------------------------------------------------------------
                           Business Loan Agreement, Page 12

<PAGE>

to the confidentiality provisions hereof. Borrower additionally waives any and
all notices of sale of participation interest, as well as all notices of any
repurchase or such participation interest in the Loans and will have all the
rights granted under the participation agreement or agreements governing the
sale of such participation interests. Any costs associated with the attempt to
arrange any such participation interest will be borne by Lender.

    SECTION 10.6  NOTICES.
All notices required to be given under this Agreement shall be given in writing

written notice to the other parties, specifying that the purpose of the notice

    SECTION 10.9  WAIVER.
Lender shall not be deemed to have waived any rights under this Agreement,
unless such waiver is given in writing and signed by Lender.  No delay or
omission on the part of Lender in exercising any right shall operate as a waiver
of such right or any other right.  A waiver by Lender of a provision of this
Agreement shall not prejudice or constitute a waiver of Lender's right otherwise
to demand strict compliance with that provision or any other provision of this
Agreement.  No prior  waiver by Lender, nor any course of dealing between Lender
and Borrower, shall constitute a waiver of any of Lender's rights or of any
obligations of Borrower as to any future transactions.  Whenever the consent of
Lender is required under this Agreement, the granting of such consent by Lender
in any instance shall not constitute continuing consent in subsequent instances
where such consent is required and in all cases such consent may be granted or
withheld in the sole discretion of Lender.


    SECTION 10.10.  CONFIDENTIALITY.

of care that it exercises with respect to its own proprietary information of the

received or received pursuant to this Agreement except that disclosure of such
information may be made (i)  to the subsidiaries of affiliates of Lender in

Principal Amount:  $ 2,000,000.00           Interest Rate: 9.0 %
Date of Note:  September 27, 1996

PROMISE TO PAY CV THERAPEUTICS, INC. ("Borrower") promises to pay to HAMBRECHT &
QUIST GUARANTY FINANCE, LLC ("Lender"), or order, in lawful money of the United
States of America, the principal amount of Two Million Dollars ($2,000,000.00),
or so much as may be outstanding, together with interest on the unpaid
outstanding principal balances from September 27, 1996 until such balance is
paid in full.

PAYMENT OF ACCRUED INTEREST: Except as provided below, Borrower will pay all
interest accrued on this Note in arrears on the first day of each month
following a month in which any principal is outstanding (or October 1, 1996, in
the case of the first month).  Interest will be computed on a 365/360 day basis
compounding monthly; that is in each month 1/360 of the Nine Percent annual
interest rate, will be multiplied by (I) the sum of (a) the outstanding
principal balance and (b) accumulated interest through the end of the prior
month and (II) the actual number of days that the principal was outstanding in
such month.

Beginning as of the Date of this Note first written above and continuing until
(but not including) January 1, 1997, Borrower may defer payment of all accrued
interest unless (a) after September 1, 1996 Borrower sells shares of its stock
(or options or other rights to acquire such shares) with aggregate gross
proceeds of at least Thirteen Million Dollars ($13,000,000) prior to March 1,
1998, or (b) there is an occurrence of any EVENT OF DEFAULT under BUSINESS LOAN
AGREEMENT (as defined below).  When Borrower fails to qualify to defer interest
payments, all accrued unpaid interest will be due within ten (10) days of such
failure, except in the Event of Default in which case all accrued unpaid
interest will be immediately due. 
     
PAYMENT OF PRINCIPAL:  Subject to Borrower's right to prepay this outstanding
principal under this Note, on January 1, 1997 the entire amount of Principal
shall be due and payable.
    
Borrower will pay Lender at Lender's address shown above or at such other place
as Lender may designate in writing. Unless otherwise agreed or required by
applicable law, payments will be applied first to accrued unpaid interest, then
to principal, and any remaining amount to any unpaid collection costs and late

United States of America, the principal amount of Three Million Dollars
($3,000,000.00), or so much as may be outstanding, together with interest on the
unpaid outstanding principal balances from September 27, 1996 until such
balance is paid in full.

PAYMENT OF ACCRUED INTEREST: Except as provided below, Borrower will pay all
interest accrued on this Note in arrears on the first day of each month
following a month in which any principal is outstanding (or October 1, 1996, in
the case of the first month).  Interest will be computed on a 365/360 day basis
compounding monthly; that is in each month 1/360 of the Nine Percent (9.0%)
annual interest rate, will be multiplied by (I) the sum of (a) the outstanding
principal balance and (b) accumulated interest through the end of the prior
month and (II) the actual number of days that the principal was outstanding in
such month.

Beginning as of the Date of this Note first written above and continuing until
(but not including) March 1, 1998, Borrower may defer payment of all accrued
interest unless (a) after September 1, 1996 Borrower sells shares of its stock
(or options or other rights to acquire such shares) with aggregate gross
proceeds of at least Thirteen Million Dollars ($13,000,000) prior to March 1,
1998, or (b) there is an occurrence of any EVENT OF DEFAULT under BUSINESS LOAN
AGREEMENT (as defined below). When Borrower fails to qualify to defer interest
payments, all accrued unpaid interest will be due within ten (10) days of such
failure, except in the case of an Event of Default in which case all accrued
unpaid interest will be immediately due.

PAYMENT OF PRINCIPAL:  Subject to Borrower's right to prepay this outstanding
principal under this Note, beginning on April 1, 1998 and continuing through and
including  September 1, 1999, Borrower will make payment to Lender a principal
payment of One Hundred Sixty-Six Thousand Six Hundred Sixty-Six and 67/100s
Dollars ($166,666.67) on the first day of each month.

Borrower will pay Lender at Lender's address shown above or at such other place
as Lender may designate in writing. Unless otherwise agreed or required by
applicable law, payments will be applied first to accrued unpaid interest, then
to principal, and any remaining amount to any unpaid collection costs and late
charges.

FIXED INTEREST RATE.  The interest rate on this Note is nine percent (9.0%) per
annum, or, if lower, the maximum rate of interest allowed by applicable law.

PREPAYMENT. Borrower may prepay without penalty all or a portion of the amount
owed earlier than it is due, provided however that any principal amount repaid
shall not be available to Borrower for future advances.  Any prepayment of
principal shall be credited against the payments of principal set forth above in
the reverse order in which such payments would otherwise be required.

          Collateral.  A photocopy or other reproduction of this AGREEMENT or

     (d)  to execute any and all applications, documents, papers and instruments

during the continuance thereof, Secured Party and any representatives of Secured
Party shall have, in addition to all its other rights under this AGREEMENT, the

days prior written notice to Debtor (which Debtor agrees is reasonable
notification within the meaning of Section 9504(3) of the Code) of the time and
place of any public sale or the time after which any private sale is to be made
shall constitute reasonable notification.  Secured Party shall not be obligated
to make any sale of COLLATERAL regardless of notice of sale having been given.

            BUSINESS LOAN AGREEMENT and FINANCING AGREEMENT or any other of the
            RELATED DOCUMENTS, including, without limitation, any increase in
            the Secured Obligations resulting from the extension of additional
            credit to Debtor, or any of its AFFILIATES, or otherwise;
     (iii)  any taking, exchange, release, or non-perfection of any other
            collateral, or any taking, release, or amendment or waiver of or
            consent to departure from any guaranty, for all or any of the
            Secured Obligations;

            or any of the SECURED OBLIGATIONS, or any manner of sale or other
            disposition of any COLLATERAL for all or any of the SECURED
            OBLIGATIONS or any other assets of Debtor or any of its AFFILIATES;
     (v)    any change, restructuring or termination of the corporate structure
            or existence of Debtor or any of its AFFILIATES;
     (vi)   any equitable or legal defense of a surety or guarantor, other than
            the defense of payment in full of the SECURED OBLIGATIONS; or
     (vii)  any other circumstance that might otherwise constitute a defense
            available to, or a discharge of, Debtor or any third party grantor
            of a security interest.

SECTION 15. INDEMNIFICATION.

        collateral, or any taking, release, or amendment or waiver of or

        available to, or a discharge of, Debtor or any third party grantor of
        a security interest.

SECTION 15. INDEMNIFICATION.
Debtor hereby indemnifies and saves and holds Secured Party (or any persons,
employees, officers or agents designated by Secured Party) harmless from and
against any and all claims, damages, loss, liability or judgments which may be
incurred or sustained by Secured Party and such designees or asserted against
Secured Party and such designees, directly or indirectly, in connection with

<PAGE>


    2.   TERM.

    The purchase right represented by this Warrant is exercisable, in whole or
in part, at any time on or before the Expiration Date.

    3.   EXERCISE OF WARRANT; PAYMENT; ISSUANCE OF NEW WARRANT

         3.1.  Subject to Section 2 hereof, the purchase rights represented by
this Warrant may be exercised by the Holder, in whole or in part, by the
surrender of this Warrant (with the notice of exercise form attached hereto as
Appendix A duly executed) at the principal office of the Company and by the
payment to the Company, by check made payable to the Company drawn on a United
States bank and for United States dollars, or by wire transfer to an account of
the Company, of an amount equal to the then applicable Warrant Price per share
multiplied by the number of Shares then being purchased. In the event of any
exercise of the purchase right represented by this Section 3, certificates for
the Shares so purchased shall be delivered to the Holder within thirty (30) days
of receipt of such payment and, unless this Warrant has been fully exercised or
expired, a new Warrant (dated as of the date hereof) representing the portion of
the Shares, if any, with respect to which this Warrant shall not then have been
exercised shall also be issued to the Holder within such thirty (30) day period.

         3.2  The Company may require that such certificate or certificates
contain on the face thereof a legend substantially as follows:
    
    "The securities evidenced by this certificate have not been registered
    under the Securities Act of 1933, as amended, or applicable state
    securities laws and rules.  No sale, offer to sell or transfer of the
    shares represented by this certificate shall be made unless a
    registration statement under such act, and applicable state securities
    laws with respect to such shares is then in effect, or an exemption
    from such registration requirements for such laws is then in effect."

    4.   EXERCISE PRICE.  The Warrant Price at which this Warrant may be
exercised shall be the Initial Warrant Price, as adjusted from time to time
pursuant to Section 5 hereof.

    5.   ADJUSTMENT OF NUMBER AND KIND OF SHARES AND ADJUSTMENT OF WARRANT
PRICE.

         5.1  CERTAIN DEFINITIONS.     As used in this Section 5 the following
terms shall have the following respective meanings:

              (a)  OPTIONS:  rights, options or warrants to subscribe for,
    purchase or otherwise acquire shares of Common Stock or Convertible
    Securities.
    
              (b)  CONVERTIBLE SECURITIES:  any evidence of indebtedness,
    shares of stock or other securities directly or indirectly convertible into
    or exchangeable for Common Stock.

         5.2  ADJUSTMENTS.  The number and kind of securities purchasable upon
the exercise of this Warrant and the Warrant Price shall be subject to
adjustment from time to time upon the occurrence of certain events, as follows:


<PAGE>


              (a)  RECLASSIFICATION, REORGANIZATION, CONSOLIDATION OR MERGER. 
    In the case of any reclassification of the Common Stock, or any
    reorganization, consolidation or merger of the Company with or into another
    corporation (other than a merger or reorganization with respect to which
    the Company is the continuing corporation and which does not result in any
    reclassification of the Common Stock), the Company, or such successor
    corporation, as the case may be, shall execute a new warrant, providing
    that the Holder shall have the right to exercise such new warrant and upon
    such exercise to receive, in lieu of each share of the Class of Stock
    theretofore issuable upon exercise of this Warrant, the number and kind of
    securities receivable upon such reclassification, reorganization,
    consolidation or merger by a holder of shares of the same Class of Stock of
    the Company for each such share of such Class of Stock.  The aggregate
    Warrant Price of the new warrant shall be the aggregate Warrant Price in
    effect immediately prior to the reclassification, reorganization,
    consolidation or merger and the Warrant Price per share shall be
    appropriately increased or decreased.  Such new warrant shall provide for
    adjustments which shall be as nearly equivalent as may be practicable to
    the adjustments provided for in this Section 5 including, without
    limitation, adjustments to the Warrant Price and to the number of share
    issuable upon exercise of this Warrant.  The provisions of this subsection
    (a) shall similarly apply to successive reclassification, reorganizations,
    consolidations or mergers.
    
              (b)  SPLIT, SUBDIVISION OR COMBINATION OF SHARES.  If the Company
    at any time while this Warrant remains outstanding and unexpired shall
    split, subdivide or combine the Class of Stock for which this Warrant is
    then exercisable, the Warrant Price shall be proportionately decreased in
    the case of a split or subdivision or proportionately increased in the case
    of a combination. Any adjustment under this subsection (b) shall become
    effective when the split, subdivision or combination becomes effective. 
    
              (c)   STOCK DIVIDENDS.  If the Company at any time while this
    Warrant remains outstanding and unexpired shall pay a dividend with respect
    to the Class of Stock for which this Warrant is then exercisable, payable
    in shares of that Class of Stock, Options, or Convertible Securities, the
    Warrant Price shall be adjusted, from and after the date of determination
    of the shareholders entitled to receive such dividend or distributions, to
    that price determined by multiplying the Warrant Price in effect
    immediately prior to such date of determination by a fraction (i) the
    numerator of which shall be the total number of shares of that Class of
    Stock outstanding immediately prior to such dividend or distribution, and
    (ii) the denominator of which shall be the total number of shares of the
    same Class of Stock outstanding immediately after such dividend or
    distribution (including shares of that Class of Stock issuable upon
    exercise, conversion or exchange of any Option or Convertible Securities
    issued as such dividend or distribution).  If the Options or Convertible
    Securities issued as such dividend or distribution by their terms provide,
    with the passage of time or otherwise, for any decrease in the
    consideration payable to the Company, or any increase by the number of
    shares issuable upon exercise, conversion or exchange thereof (by change of
    rate or otherwise), the Warrant Price shall, upon any such decrease or
    increase becoming effective, be reduced to reflect such decrease or
    increase as if such decrease or increase became effective immediately prior
    to the issuance of the Options or Convertible Securities as the dividend or
    distribution.  Any adjustment under this subsection (c) shall become
    effective on the record date.
    

<PAGE>


              (d)  OTHER SECURITIES.  In the event the Company at any time or
    from time to time after the issuance of this Warrant makes, or fixes a
    record date for the determination of Holders of Common Stock entitled to 
    receive, a dividend or other distribution payable in securities of the 
    Company other than shares of Common Stock, then, and in each such event, 
    provision shall be made so that the Holder shall receive, upon exercise 
    hereof, in addition to the number of shares of Common Stock receivable 
    thereupon, the amount of securities of the Company which the Holder would 
    have received had this Warrant been exercised for such Common Stock on 
    the date of such event and had the Holder thereafter, during the period 
    from the date of such event to and including the date of exercise, 
    retained such securities receivable by such Holder as aforesaid during 
    such period, subject to all other adjustments called for during such 
    period under this Section 5 with respect to the rights of the Holder.

    5.3  ADJUSTMENT OF NUMBER OF SHARES.  Upon each adjustment in the Warrant
Price pursuant to subsection 9(b) and (c) of this Article 5, the number of 
Shares issuable upon exercise of this warrant shall be adjusted to the product 
obtained by multiplying the number of Shares issuable immediately prior to such
adjustment in the Warrant Price by a fraction (i) the numerator of which shall
be the Warrant Price immediately prior to such adjustment, and (ii) the
denominator of which shall be the Warrant Price immediately after such
adjustment.
    

    6.   NOTICE OF ADJUSTMENTS.  Whenever the Warrant Price shall be adjusted
pursuant to Section 5 hereof, the Company shall issue a certificate signed by
its chief financial officer or chief executive officer setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated and the Warrant
Price after giving effect to such adjustment and shall cause a copy of such
certificate to be mailed (by first class mail, postage prepaid) to the Holder.

    7.   RIGHT TO CONVERT WARRANT INTO STOCK.

         7.1  RIGHT TO CONVERT.  In addition to the rights granted under
Section 3 of this Warrant, the Holder shall have the right to require the
Company to convert (the "Conversion Right") into shares of the Class of Stock
for which the Warrant is then exercisable, as provided in this Section 7. Upon
exercise of the Conversion Right, the Company shall deliver to the Holder
(without payment by the Holder of any Warrant Price) that number of shares of
stock equal to the quotient obtained by dividing (x) the value of this Warrant
at the time of the Conversion Right is exercised (determined by subtracting the
aggregate Warrant Price immediately prior to the exercise of the Conversion
Right from the aggregate Conversion Price (as hereinafter determined) by (y) the
Conversion Price.

         7.2  METHOD OF EXERCISE.  The Conversion Right may be exercised at any
time by the Holder by the surrender of this Warrant at the principal office of
the Company together with a written statement specifying that the Holder thereby
intends to exercise the Conversion Right.  Certificates of the shares of stock
issuable upon exercise of the Conversion Right shall be delivered to the Holder
within thirty (30) days following the Company's receipt of this Warrant together
with the aforesaid written statement.


<PAGE>

         7.3  AUTOMATIC CONVERSION PRIOR TO EXPIRATION.  To the extent this
Warrant is not previously exercised, and if the fair market of one share of the
Class of Stock issuable upon exercise of this Warrant is greater than the
Warrant Price per share, this Warrant shall be deemed automatically exercised in
accordance with Section 7.1 hereof (even if not surrendered) immediately before
its expiration.  To the extent this Warrant or any portion thereof is deemed
automatically exercised pursuant to this Section 7.3, the Company agrees to 
notify Holder within a reasonable period of time of the number of shares of 
the Class of Stock, if any, Holder is to receive by reason of such automatic 
exercise.  The Company shall issue to the Holder certificates for the Shares 
issued upon such automatic conversion in accordance with Section 7.2 above, 
although the Company may condition receipt of the certificate upon surrender 
of the Warrant to the Company.  

7.4 CONVERSION PRICE.  The Conversion is determined as, for the three months
prior to any conversion of the Warrant into Common Stock:

              (a)  The highest closing sale price or, if no closing sale price
    is reported, the highest value that is the average between the ask and bid
    prices of the Common Stock quoted on any exchange or over the-counter
    market on which the Common Stock is listed, whichever is applicable, as
    published in the Western Edition of THE WALL STREET JOURNAL, if the Common
    Stock is publicly traded; or,
    
              (b)  if the Common Stock is not traded in an over-the-counter
    market or on an exchange, the highest fair market value of a single share
    of Common Stock shall be as determined in good faith by the Company's Board
    of Directors' provided; however, that if the Holder disputes in writing the
    fair market value determined by the Board of Directors within thirty (30)
    days of being informed of such fair market value, the fair market value
    shall be determined by an independent appraiser, appointed in good faith by
    the Company's Board of Directors.

    8.   TRANSFERABILITY AND NON-NEGOTIABILITY OF WARRANTS AND SHARES.  This
Warrant and the Shares issued upon exercise thereof may not be transferred or
assigned in whole or in part without compliance with applicable federal and
state securities laws by the transferor and the transferee (including, without
limitation, the delivery of investment representation letters and legal opinions
reasonably satisfactory to the Company, if reasonably requested by the Company).
Subject to the provisions of this Section 8, title to the Warrant may be
transferred in the same manner as a negotiable instrument transferable by
endorsement and delivery.  

    9.   NOTICES.  The Company shall mail to the registered Holder of the
Warrant, at its last known post office address appearing on the books of the
Company, not less than twenty (20) days prior to the date on which (a) a record
will be taken for the purpose of determining the Holders of Common Stock
entitled to dividends or subscription rights, or (b) a record will be taken (or
in lieu thereof, the transfer books will be closed) for the purpose of
determining the Holders of Common Stock entitled to notice of and to vote at a
meeting of shareholders at which any capital reorganization, reclassification of
shares of Common Stock, consolidation, merger, dissolution, liquidation, winding
up or sales of substantially all of the Company's assets shall be considered and
acted upon. 

<PAGE>


    10.  MISCELLANEOUS.  No fractional shares of the Shares shall be issued in
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the Warrant
Price then in effect.  The terms and provisions of this Warrant shall inure to
the benefit of, and be binding upon, the Company and the Holders hereof and
their respective successors and assigns.  This Warrant shall be governed by and
construed under the laws of the State of California as applied to contracts
entered into between residents of the State of California to wholly performed in
the State of California.  The representations, warranties and agreements herein
contained shall survive the exercise of the Warrant.  References to the "holder
of" include the immediate Holder of shares purchased on the exercise of this
Warrant, and the word "Holder" shall include the plural thereof.  The titles of
the section and the subscriptions of this Warrant are for convenience only and
are not to be considered in construing this Warrant.  All pronouns used in the
Warrant shall be deemed to include masculine, feminine and neuter forms.

    All shares of Common Stock or other securities issued upon the exercise of
this Warrant shall be validly issued, fully paid and nonassessable, and the
Company will pay all taxes in respect of the issuance thereof (other than any
income or capital gain taxes payable by the Holder)


IN WITNESS WHEREOF, the Warrant has been duly executed by the undersigned,
as of the 27th day of September, 1996.

<PAGE>

     2.   TERM.

     The purchase right represented by this Warrant is exercisable, in whole or
in part, at any time on or before the Expiration Date.

     3.   EXERCISE OF WARRANT; PAYMENT; ISSUANCE OF NEW WARRANT

          3.1.  Subject to Section 2 hereof, the purchase rights represented by
this Warrant may be exercised by the Holder, in whole or in part, by the
surrender of this Warrant (with the notice of exercise form attached hereto as
Appendix A duly executed) at the principal office of the Company and by the
payment to the Company, by check made payable to the Company drawn on a United
States bank and for United States dollars, or by wire transfer to an account of
the Company, of an amount equal to the then applicable Warrant Price per share
multiplied by the number of Shares then being purchased. In the event of any
exercise of the purchase right represented by this Section 3, certificates for
the Shares so purchased shall be delivered to the Holder within thirty (30)
days of receipt of such payment and, unless this Warrant has been fully
exercised or expired, a new Warrant (dated as of the date hereof) representing
the portion of the Shares, if any, with respect to which this Warrant shall not
then have been exercised shall also be issued to the Holder within such thirty
(30) day period.

          3.2  The Company may require that such certificate or certificates
contain on the face thereof a legend substantially as follows:
     
     "The securities evidenced by this certificate have not been
     registered under the Securities Act of 1933, as amended, or
     applicable state securities laws and rules.  No sale, offer to sell
     or transfer of the shares represented by this certificate shall be
     made unless a registration statement under such act, and applicable
     state securities laws with respect to such shares is then in effect,
     or an exemption from such registration requirements for such laws is
     then in effect."

     4.   EXERCISE PRICE.  The Warrant Price at which this Warrant may be
exercised shall be the Initial Warrant Price, as adjusted from time to time
pursuant to Section 5 hereof.

     5.   ADJUSTMENT OF NUMBER AND KIND OF SHARES AND ADJUSTMENT OF WARRANT
PRICE.

          5.1  CERTAIN DEFINITIONS.     As used in this Section 5 the following
terms shall have the following respective meanings:

               (a)  OPTIONS:  rights, options or warrants to subscribe for,
     purchase or otherwise acquire shares of Common Stock or Convertible
     Securities.
     
              (b)  CONVERTIBLE SECURITIES:  any evidence of indebtedness, shares
     of stock or other securities directly or indirectly convertible into or
     exchangeable for Common Stock.
     

          5.2  ADJUSTMENTS.  The number and kind of securities purchasable upon
the exercise of this Warrant and the Warrant Price shall be subject to
adjustment from time to time upon the occurrence of certain events, as follows:


<PAGE>

               (a)  RECLASSIFICATION, REORGANIZATION, CONSOLIDATION OR MERGER.
     In the case of any reclassification of the Common Stock, or any
     reorganization, consolidation or merger of the Company with or into
     another corporation (other than a merger or reorganization with respect to
     which the Company is the continuing corporation and which does not result
     in any reclassification of the Common Stock), the Company, or such
     successor corporation, as the case may be, shall execute a new warrant,
     providing that the Holder shall have the right to exercise such new
     warrant and upon such exercise to receive, in lieu of each share of the
     Class of Stock theretofore issuable upon exercise of this Warrant, the
     number and kind of securities receivable upon such reclassification,
     reorganization, consolidation or merger by a holder of shares of the same
     Class of Stock of the Company for each such share of such Class of Stock.
     The aggregate Warrant Price of the new warrant shall be the aggregate
     Warrant Price in effect immediately prior to the reclassification,
     reorganization, consolidation or merger and the Warrant Price per share
     shall be appropriately increased or decreased.  Such new warrant shall
     provide for adjustments which shall be as nearly equivalent as may be
     practicable to the adjustments provided for in this Section 5 including,
     without limitation, adjustments to the Warrant Price and to the number of
     share issuable upon exercise of this Warrant.  The provisions of this
     subsection (a) shall similarly apply to successive reclassification,
     reorganizations, consolidations or mergers.
     
               (b)     SPLIT, SUBDIVISION OR COMBINATION OF SHARES.  If the
     Company at any time while this Warrant remains outstanding and unexpired
     shall split, subdivide or combine the Class of Stock for which this
     Warrant is then exercisable, the Warrant Price shall be proportionately
     decreased in the case of a split or subdivision or proportionately
     increased in the case of a combination. Any adjustment under this
     subsection (b) shall become effective when the split, subdivision or
     combination becomes effective.
     
               (c)  STOCK DIVIDENDS.  If the Company at any time while this
     Warrant remains outstanding and unexpired shall pay a dividend with
     respect to the Class of Stock for which this Warrant is then exercisable,
     payable in shares of that Class of Stock, Options, or Convertible
     Securities, the Warrant Price shall be adjusted, from and after the date
     of determination of the shareholders entitled to receive such dividend or
     distributions, to that price determined by multiplying the Warrant Price
     in effect immediately prior to such date of determination by a fraction
     (i) the numerator of which shall be the total number of shares of that
     Class of Stock outstanding immediately prior to such dividend or
     distribution, and (ii) the denominator of which shall be the total number
     of shares of the same Class of Stock outstanding immediately after such
     dividend or distribution (including shares of that Class of Stock issuable
     upon exercise, conversion or exchange of any Option or Convertible
     Securities issued as such dividend or distribution).  If the Options or
     Convertible Securities issued as such dividend or distribution by their
     terms provide, with the passage of time or otherwise, for any decrease in
     the consideration payable to the Company, or any increase by the number of
     shares issuable upon exercise, conversion or exchange thereof (by change
     of rate or otherwise), the Warrant Price shall, upon any such decrease or
     increase becoming effective, be reduced to reflect such decrease or
     increase as if such decrease or increase became effective immediately
     prior to the issuance of the Options or Convertible Securities as the
     dividend or distribution.  Any adjustment under this subsection (c) shall
     become effective on the record date.
     
<PAGE>

               (d)  OTHER SECURITIES.  In the event the Company at any time 
     or from time to time after the issuance of this Warrant makes, or fixes 
     a record date for the determination of Holders of Common Stock entitled 
     to receive, a dividend or other distribution payable in securities of 
     the Company other than shares of Common Stock, then, and in each such 
     event, provision shall be made so that the Holder shall receive, upon 
     exercise hereof, in addition to the number of shares of Common Stock 
     receivable thereupon, the amount of securities of the Company which the 
     Holder would have received had this Warrant been exercised for such 
     Common Stock on the date of such event and had the Holder thereafter, 
     during the period from the date of such event to and including the date 
     of exercise, retained such securities receivable by such Holder as 
     aforesaid during such period, subject to all other adjustments called 
     for during such period under this Section 5 with respect to the rights 
     of the Holder.

     5.3  ADJUSTMENT OF NUMBER OF SHARES.  Upon each adjustment in the Warrant
Price pursuant to subsection 9(b) and (c) of this Article 5, the number of
Shares issuable upon exercise of this warrant shall be adjusted to the product
obtained by multiplying the number of Shares issuable immediately prior to such
adjustment in the Warrant Price by a fraction (i) the numerator of which shall
be the Warrant Price immediately prior to such adjustment, and (ii) the
denominator of which shall be the Warrant Price immediately after such
adjustment.
     
     
     6.   NOTICE OF ADJUSTMENTS.  Whenever the Warrant Price shall be 
adjusted pursuant to Section 5 hereof, the Company shall issue a certificate 
signed by its chief financial officer or chief executive officer setting 
forth, in reasonable detail, the event requiring the adjustment, the amount 
of the adjustment, the method by which such adjustment was calculated and the 
Warrant Price after giving effect to such adjustment and shall cause a copy 
of such certificate to be mailed (by first class mail, postage prepaid) to 
the Holder.

     7.   RIGHT TO CONVERT WARRANT INTO STOCK.

          7.1  RIGHT TO CONVERT.  In addition to the rights granted under
Section 3 of this Warrant, the Holder shall have the right to require the
Company to convert (the "Conversion Right") into shares of the Class of Stock
for which the Warrant is then exercisable, as provided in this Section 7. Upon
exercise of the Conversion Right, the Company shall deliver to the Holder
(without payment by the Holder of any Warrant Price) that number of shares of
stock equal to the quotient obtained by dividing (x) the value of this Warrant
at the time of the Conversion Right is exercised (determined by subtracting the
aggregate Warrant Price immediately prior to the exercise of the Conversion
Right from the aggregate Conversion Price (as hereinafter determined) by (y)
the Conversion Price.

          7.2  METHOD OF EXERCISE.  The Conversion Right may be exercised at
any time by the Holder by the surrender of this Warrant at the principal office
of the Company together with a written statement specifying that the Holder
thereby intends to exercise the Conversion Right.  Certificates of the shares
of stock issuable upon exercise of the Conversion Right shall be delivered to
the Holder within thirty (30) days following the Company's receipt of this
Warrant together with the aforesaid written statement.

<PAGE>

          7.3  AUTOMATIC CONVERSION PRIOR TO EXPIRATION.  To the extent this
Warrant is not previously exercised, and if the fair market of one share of the
Class of Stock issuable upon exercise of this Warrant is greater than the
Warrant Price per share, this Warrant shall be deemed automatically exercised
in accordance with Section 7.1 hereof (even if not surrendered) immediately
before its expiration.  To the extent this Warrant or any portion thereof is
deemed automatically exercised pursuant to this Section 7.3, the 
Company agrees to notify Holder within a reasonable period of time of the 
number of shares of the Class of Stock, if any, Holder is to receive by 
reason of such automatic exercise.  The Company shall issue to the Holder 
certificates for the Shares issued upon such automatic conversion in 
accordance with Section 7.2 above, although the Company may condition receipt 
of the certificate upon surrender of the Warrant to the Company.

7.4  CONVERSION PRICE.  The Conversion is determined as, for the three months
prior to any conversion of the Warrant into Common Stock:

               (a)  The highest closing sale price or, if no closing sale price
     is reported, the highest value that is the average between the ask and bid
     prices of the Common Stock quoted on any exchange or over the-counter
     market on which the Common Stock is listed, whichever is applicable, as
     published in the Western Edition of THE WALL STREET JOURNAL, if the Common
     Stock is publicly traded; or,
     
               (b)  if the Common Stock is not traded in an over-the-counter
     market or on an exchange, the highest fair market value of a single share
     of Common Stock shall be as determined in good faith by the Company's
     Board of Directors' provided; however, that if the Holder disputes in
     writing the fair market value determined by the Board of Directors within
     thirty (30) days of being informed of such fair market value, the fair
     market value shall be determined by an independent appraiser, appointed in
     good faith by the Company's Board of Directors.

     8.   TRANSFERABILITY AND NON-NEGOTIABILITY OF WARRANTS AND SHARES.  This
Warrant and the Shares issued upon exercise thereof may not be transferred or
assigned in whole or in part without compliance with applicable federal and
state securities laws by the transferor and the transferee (including, without
limitation, the delivery of investment representation letters and legal
opinions reasonably satisfactory to the Company, if reasonably requested by the
Company).  Subject to the provisions of this Section 8, title to the Warrant
may be transferred in the same manner as a negotiable instrument transferable
by endorsement and delivery.

     9.   NOTICES.  The Company shall mail to the registered Holder of the
Warrant, at its last known post office address appearing on the books of the
Company, not less than twenty (20) days prior to the date on which (a) a record
will be taken for the purpose of determining the Holders of Common Stock
entitled to dividends or subscription rights, or (b) a record will be taken (or
in lieu thereof, the transfer books will be closed) for the purpose of
determining the Holders of Common Stock entitled to notice of and to vote at a
meeting of shareholders at which any capital reorganization, reclassification
of shares of Common Stock, consolidation, merger, dissolution, liquidation,
winding up or sales of substantially all of the Company's assets shall be
considered and acted upon.

<PAGE>

     10.  MISCELLANEOUS.  No fractional shares of the Shares shall be issued in
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the Warrant
Price then in effect.  The terms and provisions of this Warrant shall inure to
the benefit of, and be binding upon, the Company and the Holders hereof and
their respective successors and assigns.  This Warrant shall be governed by and
construed under the laws of the State of California as applied to contracts
entered into between residents of the State of California to wholly performed
in the State of California.  The representations, warranties and agreements
herein contained shall survive the exercise of the Warrant.  References to the
"holder of"  include the immediate Holder of shares purchased on the exercise 
of this Warrant, and the word "Holder" shall include the plural thereof.  The 
titles of the section and the subscriptions of this Warrant are for convenience 
only and are not to be considered in construing this Warrant.  All pronouns 
used in the Warrant shall be deemed to include masculine, feminine and neuter 
forms.

     All shares of Common Stock or other securities issued upon the exercise of
this Warrant shall be validly issued, fully paid and nonassessable, and the
Company will pay all taxes in respect of the issuance thereof (other than any
income or capital gain taxes payable by the Holder)


IN WITNESS WHEREOF, the Warrant has been duly executed by the undersigned, as
of the 27th day of September, 1996.
