                                  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 is an adenosine A(1) receptor antagonist discovered by CVT.
Adenosine A(1) receptor antagonists block certain actions of adenosine, a
hormone that modulates different functions of the cardiovascular system. CVT-124
has potential applications in the treatment of edema (fluid accumulation)
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 (pain in the legs due to insufficient blood flow), 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.
 
                                       4
<PAGE>
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 useful in a variety
of cellular proliferative disorders, including the prevention of restenosis, as
an adjunct to coronary artery bypass surgery and as a treatment for
cardiomyopathy (heart muscle damage). 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,

                                  RISK FACTORS
 
   
The Common Stock offered hereby involves a high degree of risk. The principal
risks of the Offering include uncertainties related to the Company's early stage
of development, including the fact that the Company has no commercially
available products primarily due to the lack of marketing approval from
regulatory authorities, uncertainties related to clinical trials of ranolazine
and CVT-124 and has incurred significant losses to date. See "Risk Factors."

                                  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."
 
HISTORY OF LOSSES AND EXPECTATION OF FUTURE LOSSES; 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
 
                                       8
<PAGE>
future. The Company will not receive product revenues unless and until it
completes clinical trials with respect to 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; RAPID TECHNOLOGICAL CHANGE
 
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 17.96% 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 6,949,166 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
4,449,166 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,
92,785 shares will be eligible for sale in the public market immediately
following the Offering. Beginning 180 days after commencement of the Offering,
2,481,313 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 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 303,078 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
issuable upon exercise of warrants which are not subject to lock-up agreements,
will
 
                                       13
<PAGE>
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."

                                  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 792,898 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

repayment of the $2.0 million term loan portion of a debt financing with
entities associated with Hambrecht & Quist Group:

                                    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 792,898 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:

difference between existing stockholders and purchasers of shares in the
Offering (at an assumed initial public offering price of $13.00 per share and

                    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 Bayer AG.
 
   
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 Syntex 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.
 
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 will be recorded and amortized to both research and development
expenses as well as general and administrative expenses over the related vesting
periods of the options granted during the nine months ended September 30, 1996.
 
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 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.
 
                                       20
<PAGE>
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 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 $1.1 million in the
year ended December 31, 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. The Company intends to convert the term loan into an equipment
lease if it does not complete the Offering prior to December 31, 1996. 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 equipment 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 is an adenosine A(1) receptor antagonist discovered by CVT.
Adenosine A(1) receptor antagonists block certain actions of adenosine, a
hormone that modulates different functions of the cardiovascular system. CVT-124
has potential applications in the treatment of edema (fluid accumulation)
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 (pain in the legs due to
insufficient blood flow), 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 coronary artery bypass surgery and as a treatment for
cardiomyopathy (heart muscle damage). 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
 
                                       22
<PAGE>
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 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.
 
           Graphical description of sodium reabsorption in the kidney
 
                                       25
<PAGE>
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.
 
      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
 
                                       26
<PAGE>
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.
 
                                       27
<PAGE>
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 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.
 
                                       28
<PAGE>
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.
 
                                       29
<PAGE>
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 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.
 
                                       30

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 Company may be obligated to make
milestone payments totaling $3.0 million to Syntex in 1997 unless the Company
elects to terminate the agreement. 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 a non-refundable
license fee of $250,000, 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, 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
 
                                       31
<PAGE>
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. 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,
 
                                       32
<PAGE>
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.
 
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
 
                                       33
<PAGE>
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 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
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
 
                                       35
<PAGE>
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 $7,500; (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.
 
The Company entered into a Separation and Consulting Agreement with Thomas L.
Gutshall effective as of September 2, 1996. 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.

purchase one-half share of Series E Preferred Stock at an exercise price of
$20.00 per share) in September 1995 and November 1995; and an aggregate of
653,592 shares of Series G Preferred Stock and warrants to purchase an aggregate
of 980,392 shares of Common Stock at a purchase price of $20.00 per unit (with

March 1996 and May 1996.

The Company has provided Louis G. Lange, M.D., Ph.D., Chairman of the Board of
Directors and Chief Executive Officer, with several loans. In August 1992, the
Company provided a loan in the principal amount of $500,000 at an annual
interest rate of 7.0%, pursuant to a promissory note secured by a deed of trust
on Dr. Lange's residence (the "1992 Note"). In June 1993, the Company provided a
loan in the principal amount of $25,000 at an annual interest rate of 5.33%,

In April 1995, the Company forgave $30,000 in interest due on the notes. In

amended note, the loans bear interest at the rate of 6.53% compounded

amount necessary to compensate him for any taxes that he may incur due to the

to which Imperial Bank provided a loan to the Company in the principal amount of
$500,000, at an annual interest rate equal to the greater of 2.0% per year in
excess of Imperial Bank's prime lending rate or $250 (the "Imperial Loan"). The
loan was guaranteed by Institutional Venture Partners V, L.P. ("IVP") pursuant
to a Continuing Guarantee dated August 11, 1992 (the "IVP Guarantee"). Mr.
Colella, a director of the Company, is a General Partner of IVP. In
consideration for the IVP Guarantee, Dr. Lange executed a Guaranty and Pledge
Agreement dated August 18, 1992 in which he provided a guarantee of
reimbursement and pledged shares in favor of IVP. The Company paid off the
Imperial Loan in September 1996.
 
Upon the closing of this Offering, Dr. Lange will sell a sufficient number of
shares of Common Stock at the price per share set in the Offering to the Company
to satisfy $150,000 of his $500,000 loan and the tax obligations arising from
such sale.
 
In August 1995, in connection with the exercise of an option to purchase 30,000
shares of Common Stock, the Company provided a loan to Michael M. Wick, M.D.,
Ph.D., Senior Vice President, Research, in the principal

amount of $75,000, at an annual interest rate of 6.56%, pursuant to a promissory
note secured by a pledge of 7,500 shares of Common Stock held by Dr. Wick. In
December 1995, the Company repurchased the 30,000 shares for an aggregate amount
of $75,000. Payment was made by cancellation of the note.
 
In June 1995, in connection with the exercise of an option to purchase Common
Stock, the Company provided a loan to Thomas L. Gutshall, a director of the
Company who then served as President and Chief Operating Officer, in the
principal amount of $62,500, at an annual interest rate of 7.31%, pursuant to a
promissory note secured by a pledge of 25,000 shares of Common Stock held by Mr.
Gutshall. Pursuant to a Separation and Consulting Agreement effective as of
September 2, 1996, the Company agreed to amend the note. Under the terms of the
amended note, the loan bears interest at the rate of 6.53% compounded
semi-annually and the outstanding principal amount is due on the earliest of
December 31, 2001, the voluntary termination of association or a change in
control. As of September 30, 1996, an aggregate principal amount of $62,500
remained outstanding on the note.
 
In November 1992, the Company provided two loans to George F. Schreiner, M.D.,
Ph.D., Vice President, Medical Science and Preclinical Research, both in the
principal amounts of $75,000, at an annual interest rate of 6.5%. The
outstanding principal amount and accrued interest on the first loan was forgiven
in three equal amounts on the last day of the year of 1993, 1994 and 1995. The
second loan was made pursuant to a promissory note secured by a deed of trust on
Dr. Schreiner's residence. In September 1996, the Company amended the note.
Under the terms of the amended note, the loan bears interest at the rate of
6.53% compounded semi-annually and the outstanding principal amount is due on
the earliest of December 31, 2001, the termination of employment or a change in
control. As of September 30, 1996, an aggregate of $75,000 in principal amount
remained outstanding on the second loan. In December 1992, the Company provided
a third loan to Dr. Schreiner in the principal amount of $50,000, at an annual
interest rate of 6.5%, pursuant to a promissory note secured by a deed of trust
on Dr. Schreiner's residence (the "December Note"). Dr. Schreiner repaid the
outstanding principal amount and accrued interest on the December Note in May
1993.
 
The forgiveness of the accrued interest on the notes to Dr. Lange and Dr.
Schreiner was accounted for as compensation expense to the related employees, in
the period in which the interest was deemed to have been forgiven.
 
OTHER TRANSACTIONS/RELATIONSHIPS
 
In May 1995, the Company entered into a Consulting Agreement with Kathleen A.
Stafford, Chief Financial Officer of the Company. As compensation for her
services under the agreement, Ms. Stafford received $1,900 per week as well as

Agreement with Genta Incorporated and Genta Jago Technologies B.V. (the "Genta
Agreement"). Mr. Colella, a director of the Company, is also a director of Genta
Incorporated. Pursuant to the terms of the Genta Agreement, the parties agreed
to engage in a five-year collaboration to design, develop and commercialize
certain products utilizing the technology which was the subject of a License
Agreement between the Company and Genta Incorporated on the one hand and the
Board of Trustees of the Leland Stanford Junior University on the other hand
(the "Stanford License"). The parties have terminated the collaboration effort,
and the Stanford License has been terminated.
 
In October 1996, the Company entered into indemnification agreements with its
directors and officers for the indemnification of, and advancement of expenses
to, such persons to the full extent permitted by law. The Company intends to
execute such agreements with its future directors and officers.
 
The Company believes that the foregoing transactions were in its best interest.
As a matter of policy the transactions were, and all future transactions between
the Company and any of its officers, directors or principal shareholders will
be, approved by a majority of the independent and disinterested members of the
Board of Directors, will be on terms no less favorable to the Company than could
be obtained from unaffiliated third parties and will be in connection with bona
fide business purposes of the Company.

                          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 4,449,166 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
 
                                       53
<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 6,949,166 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 4,449,166 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, 92,785 shares will be eligible for sale in the
public market immediately following the Offering. Beginning 180 days after
commencement of this Offering, 2,481,313 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 1,875,068 Restricted Shares, which are also
subject to such lock-up agreements, will have been held for less than two 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."
 
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
 
                                       55
<PAGE>
become eligible for sale in the public markets subject to Rule 144 beginning 180
days after commencement of this Offering and 303,078 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 issuable upon
exercise of warrants 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.
 
                                       57
<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.
 
                                 LEGAL MATTERS

Company by Cooley Godward LLP ("Cooley"), Palo Alto, California. Certain legal
matters in connection with this Offering will be passed upon for the
Underwriters by Wilson Sonsini Goodrich & Rosati, a Professional Corporation,

formed by the partners of Cooley for investment purposes, owns 18,761 shares of
the Company's Common Stock, 1,514 shares of Common Stock issuable upon the net
exercise of an outstanding warrant upon the closing of the Offering and a

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 at December 31,
1994 consist primarily of auction market preferred stock, money market capital
notes, and bank notes. At September 30, 1996, all short-term investments are in
U.S. government bonds. 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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED)
 
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.
 
REVENUE RECOGNITION
 
Revenues related to license agreements with noncancelable, nonrefundable terms
and no significant future obligations are recognized upon execution of the
agreements. Milestone payments will be recognized pursuant to collaborative
agreements upon the achievement of specified milestones.
 
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).

addition, 792,898 shares will be issued in connection with the net exercise of
certain warrants upon the closing of the initial public offering. Pro forma
stockholders' equity at September 30, 1996, as adjusted for the conversion of

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 a $250,000 up
front non-refundable license fee and is entitled to receive milestone payments
and royalties in the future.

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
September 1999. The Company intends to convert the term loan into an equipment
lease if it does not complete its initial public offering by December 31, 1996.
Therefore, the term loan has been classified as long term in the balance sheet
at September 30, 1996. If the Company does not raise a minimum of $13.0 million
in gross proceeds through the sale of equity securities, the Company can elect
to defer payments under either the term loan (or the equipment 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. Also, see Note 8.
 
6.  LEASES
The Company leases certain equipment and furniture under noncancelable capital
leases. The Company leases its facilities under noncancelable operating leases.
The facilities lease expires February 2002 and includes an option to renew the
lease for an additional five years. In October 1995, the Company entered into a
noncancelable sublease agreement whereby it leased additional space to two
separate companies for eight months and 17 months, respectively. Aggregate
future minimum rentals to be received as of December 31, 1995 totaled $487,000.
 
Following is a schedule of future minimum lease payments at December 31, 1995,
net of sublease rentals in 1996 and 1997:

Preferred stockholders are entitled to noncumulative dividends at the rate of
$0.08, $0.25, $0.125, $0.20, $0.20 and $0.20 per annum, for each share of Series
A, Series B, Series C, Series D, Series E and Series G preferred stock
outstanding, respectively, if declared by the board of directors, payable in
preference to common stock dividends. No dividends have been declared or paid by
the Company.
 
Pursuant to the Company's Restated Certificate of Incorporation, as amended, the
liquidation preference includes all declared but unpaid dividends, if any. None
have been declared to date. After payment has been made to the preferred
stockholders, holders of the common stock and preferred stock shall receive the
remaining assets. Such assets shall be distributed ratably among such holders in
proportion to the shares of stock held by them.
 
Each share of preferred stock votes equally with shares of common stock on an
"if-converted" basis at any annual or special meeting of the Company, and may
act by written consent in the same manner as the common stock. Series A, Series
B (if and when issued) Series C, Series D, Series E and Series G preferred
stockholders have the right of first refusal with respect to additional equity
financings the Company undertakes.
 
Each share of preferred stock is convertible at any time at the option of the
holder. After giving effect to the reverse stock split which occurred on October
29, 1996, the conversion ratio is 1-for-10. Conversion of the preferred stock is
automatic upon the closing of an initial public offering with gross proceeds in
excess of $10,000,000. See Note 10. The Company has reserved 3,238,185 shares of
its common stock for the conversion of its outstanding preferred stock.
 
If the Company issues stock for a price per share less than the Series E
conversion price, then the Series E and Series G conversion prices shall be
reduced to the amount equal to the consideration per share for which such
additional shares of stock are issued. This provision shall terminate upon the
first to occur of the closing of an initial public offering in excess of
$10,000,000 or a merger, reorganization or sale of substantially all of the
assets of the Company or the closing of the Company's next financing of at least
$5,000,000.

COMMON STOCK
 
In November 1992, the Company repurchased 40,000 shares of its common stock from
its founders for $0.60 per share. The original purchase price was recorded as a
reduction to common stock, at stated cost, and the excess over the original
purchase price, or $23,600, was recorded in the caption "deficit accumulated
during the development stage."
 
1992 STOCK OPTION PLAN
 
The Company has reserved 345,000 common shares for issuance under its revised
1992 Stock Option Plan which provides for common stock options to be granted to
employees (including consultants, officers, and directors). The exercise price
of each incentive stock option shall be not less than the 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 stock 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. All options are to have a term not greater than 10 years from the date
of grant. Options are exercisable upon vesting, which is generally ratable over
a five-year period, unless otherwise approved by the board of directors.
 
1994 EQUITY INCENTIVE PLAN
 
In February 1994, the Company's board of directors adopted the 1994 Equity
Incentive Plan. Under the Plan, up to 500,000 shares of the Company's common
stock may be granted to employees of and consultants to the Company and its
affiliates. The Plan allows for the grant of incentive stock options,
nonstatutory stock options, stock bonuses, rights to purchase restricted stock
and stock appreciation rights. Options granted under this plan expire no later
than 10 years from the date of grant. The exercise price of each incentive stock
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
common stock may be granted to directors of the Company who is not otherwise an
employee of or consultant to the Company or of any affiliate of the Company.
Options granted under this plan expire no later than 10 years from the date 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.

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
$2.00 per share (21,926 shares of common stock at $20.00 per share on an

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
December 31, 1995, 21,926 shares of common stock have been reserved for the
exercise of the warrants.
 
In connection with the sale of Series E preferred stock, the Company issued
warrants to purchase 1,960,800 shares of the Company's Series E preferred stock
at $2.00 per share (196,078 shares of common stock at $20.00 per share on an
as-if-converted basis). The warrants are exercisable immediately and expire at
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
December 31, 1995, 196,078 shares of common stock have been reserved for the
exercise of the warrants.
 
In 1995, the Company issued its corporate attorneys a warrant to purchase 25,000
units consisting of one share of the Company's Series E preferred stock (2,500
shares of common stock on an as-if converted basis) and one warrant to purchase
half of one share of Series E preferred stock for $2.00 per share (1,250 shares
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
agreement. Shares of common stock totaling 3,750 have been reserved for issuance
upon exercise of the warrant.

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

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.

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
was effected on October 29, 1996. Effective upon the closing of the initial
public offering, the Company will become authorized to issue 5,000,000 shares of
$0.001 par value preferred stock and 30,000,000 shares of $0.001 par value
common stock. All par value, share and per share amounts, as well as the

accompanying financial statements have been retroactively adjusted to reflect
the reverse stock split.
 
In September 1996, the board of directors adopted the Employee Stock Purchase
Plan, the amended and restated Non-Employee Directors' Stock Option Plan and the
amended and restated 1992 Stock Option Plan and the amended and restated 1994
Equity Incentive Plan. In September 1996, the stockholders approved such plans.
A total of 1,545,000 shares of common stock have been reserved for issuance
thereunder, subject to stockholder approval.
 
On August 25, 1996, a promissory note was executed in favor of the Company by an
officer, for $25,000, bearing interest at 6.84%, per annum. The principal is due
and payable on August 25, 2001. The note is secured by a pledge of shares of the
Company's common stock.

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.

The share amounts set forth give effect to the Company's 1-for-10 reverse stock
split of the Company's Common Stock effected in October 1996. The sales and
issuances of securities in the transactions described in paragraphs (2)-(9) were
deemed to be exempt from registration under the Securities Act by virtue of
Section 4(2), Regulation D or Regulation S promulgated thereunder. With respect
to the grant of stock options described in paragraph (1), an exemption from
registration was unnecessary in that none of the transactions involved a "sale"
of securities as such term is used in Section 2(3) of the Securities Act.
 
Appropriate legends are affixed to the stock certificate issued in the
aforementioned transactions. Similar legends were imposed in connection with any
subsequent sales of any such securities. All recipients received adequate
information about the Company or had access, through employment or other
relationships, to such information.

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.

[      ].  The payment of such interest shall not foreclose UFRFI from
exercising any other rights it may have as a consequence of the lateness of any
payment.


                   ARTICLE VI - PATENT PROSECUTION AND INFRINGEMENT

    6.1   During the term of this Agreement, [       ] will be responsible for
filing, prosecuting and maintaining patent applications with respect to the
Patent Rights, at its own expense.  [  ] will retain patent counsel of its
choosing but reasonably acceptable to [         ] in connection with the
performance of [         ] obligations under this Section 6.1 and shall
designate [     ] as an additional client with respect to such representation.
As an additional client, [      ] shall be entitled to receive copies of
correspondence and filings with the U.S. Patent and Trademark office and foreign
equivalents and to be consulted regarding such patent applications.

    6.2   [      ] will cooperate with [      ] in the preparation, filing,
prosecution and maintenance of patents and patent applications with respect to
the Patent Rights by disclosing such information as may be necessary and by
promptly executing such documents as [        ] may reasonably request to effect
such efforts.

    6.3   If [      ] wishes to file a patent application with respect to any
invention claimed in the Patent Rights in any jurisdiction in which no
application has yet been filed, [      ] will so notify [         ] in writing,
upon receipt of which [      ] will have ninety (90) days to file such patent
application.  If [      ] declines or fails to file such patent application, [
  ] may file and prosecute such patent application, at [         ] own expense.
In such event, [        ] will have no rights under Section 2.1 to practice the
invention disclosed in such patent application in such jurisdiction.

    6.4   If [        ] intends to abandon all claims under all patent
applications contained in the Patent Rights in a particular jurisdiction, it
will notify [      ] within ninety (90) days of its proposed abandonment, but no
later than thirty (30) days prior to any deadline for filing any response or
taking any action necessary to maintain such application.  Upon receipt of such
notice [      ] may, by written notice to [      ], elect to continue the
prosecution of such application.  The costs and expenses associated such
prosecution will be borne solely by [    ]; provided, however, that if [      ]
obtains issuance of any such patent application, [      ] shall reimburse [
 ] for such costs and expenses.  [      ] determination to abandon any patent
application hereunder will have no force and effect upon the license granted
with respect to such patent application pursuant to Section 2.1.

    6.5   For so long as [                                     ] under this 
Agreement, [
                       ] shall be responsible, solely at its expense, for
defending and enforcing the Patent Rights.  However, [      ] shall receive
notice of and shall have the right, at its expense, to participate in the
protection and defense of the Patent Rights.  [      ] shall have the right to
settle and compromise any dispute with third parties, with the prior written
consent of [      ], which consent shall not be unreasonably withheld.  All
costs, fees and expenses incurred in connection

] , provided, however, that [
                                                              ] and [
            ] in connection therewith.  Said [                  ] shall begin no
earlier than the date [

].  Any [


                                                         ] pursuant to this
Article VI.  [
                                           ]  To the extent that [

                  ]  shall be entitled to [

                                                             ] under this
Agreement.
[      ] agrees to cooperate reasonably in any such litigation initiated by [
   ] including participating as a necessary party, supplying essential
documentary evidence and making essential witnesses in [      ]  employment
available.

    6.6   If [        ]  does not, within ninety (90) days after receiving
notice or otherwise becoming aware of a third party infringement of any of the
Patent Rights, take appropriate action to address such third party infringement,
then [      ] may take such legally permissible action as it deems necessary or
appropriate to enforce the Patent Rights and restrain such infringement.  In
such event, all costs, fees and expenses incurred in connection with the defence
and enforcement of the Patent Rights shall be borne by [      ].  [        ]
agrees to cooperate reasonably in any such litigation initiated by [      ]
including participating as a necessary party, supplying essential documentary
evidence and making essential witnesses in [        ] 's employment available.
If [      ] shall prevail in such proceeding, either by way of judgment or
settlement or compromise, any amounts recovered by [      ] shall be divided
equally between the parties, net of expenses incurred in connection therewith,
with the payment made promptly after such receipt of such amounts.

    6.7   If [            ]  has a [                   ] under this Agreement,
the parties shall discuss [                                                ].

    7.1   Licensee shall at all times during the term of this Agreement and
thereafter, indemnify, defend and hold UFRFI, the USF Research Foundation Inc.

MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND, EITHER EXPRESS
OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, AND VALIDITY OF PATENT RIGHTS CLAIMS, ISSUED OR

                            ARTICLE VIII - CONFIDENTIALITY

    8.1   Anything in this Agreement to the contrary notwithstanding, any and
all knowledge, know-how, practices, process or other information of any kind and
in any form (hereinafter referred to as "Confidential Information") disclosed or
submitted, either orally, in writing or in other tangible or intangible form
which is designated as Confidential Information, to either party by the other
shall be received and maintained by the receiving party in strict confidence and
shall not be disclosed to any third party.  Furthermore, neither party shall use
the said Confidential Information for any purpose other than those purposes
specified in this Agreement.  The parties may disclose Confidential Information
to the minimum number of its employees reasonably requiring access thereto for
the purposes of this Agreement provided, however, that prior to making any such
disclosures each such employee shall be apprised of the duty and obligation to
maintain Confidential Information in confidence and not to use such information
for any purpose other than in accordance with the terms and conditions of this

becomes available to the public through no act of the receiving party; or

          (b) Was independently known prior to receipt thereof, or made

2.  GRANT OF RIGHTS.

    2.1     Syntex herewith grants to CVT under the Syntex Patent Rights and
Syntex Know-How for the Cardiovascular Indications:

            (a)    an exclusive right and license to develop and register the
Licensed Product(s) in the CVT Territory for angina pectoris and, at CVT's
discretion, certain other Cardiovascular Indications; and

            (b)    an exclusive right and license to make, have made, use,
offer for sale, sell and import the Licensed Product(s) in the CVT Territory for
angina pectoris and, at CVT's discretion, certain other Cardiovascular
Indications.
    No rights are granted pursuant to the foregoing license under the Syntex
Patent Rights and Know-how to any compounds other than the Licensed Compounds.

    2.2     The exclusiveness as per Section 2.1 above shall be valid against
Syntex in the CVT Territory, unless specifically provided for to the contrary
under this Agreement.


                                          6.

<PAGE>

    2.3     CVT shall be permitted to extend its right and license obtained
under this Agreement to its Affiliates and to grant sublicenses to third parties
in the CVT Territory.  Unless expressly stated to the contrary, all references
in this Agreement to sublicensees of CVT shall include the CVT Partner.  CVT
shall inform Syntex in writing of the identity of its sublicensees, including
the CVT Partner, and any Affiliates to which it has extended rights, promptly
after such parties have obtained such rights.

    2.4     If at any time CVT or the CVT Partner for reasons of seeking a
marketing partner decides that it desires to sublicense its rights granted in
Section 2.1 to a third party in a given country of the CVT Territory, CVT or the
CVT Partner, as the case may be, shall give Syntex written notice to such effect
identifying the country or countries.  Syntex shall have forty-five (45) days 
from receipt of such notice to inform CVT, or the CVT Partner, as the case may 
be, by written notice that Syntex elects to exercise a right of first 
negotiation to obtain such sublicense with respect to the country or 
countries in question and provide at the time of such election a proposal of 
terms relating to the Licensed Product and country or countries in question.  
If the election is in the affirmative, Syntex or any Affiliate of Syntex 
shall have a right of first negotiation, such right giving Syntex or its 
Affiliate, during the one hundred and twenty (120) day period following 
delivery of the notice (the "Negotiation Period"), the exclusive right to 
negotiate with CVT or the CVT Partner, before CVT or the CVT Partner 
negotiates with any third party, to participate in marketing a Licensed 
Product in any portion of the CVT Territory in which CVT or the CVT Partner 
plans to seek assistance in marketing the Licensed Product; provided, 
however, that the foregoing shall not apply to CVT's selection of a CVT 
Partner, or if CVT or the CVT Partner at the time of launch of Licensed
Product has in the relevant portion of the CVT Territory an established and 
systematic commercial relationship with a third party for the marketing by 
such third party of other products developed by CVT or the CVT Partner, as 
the case may be, and CVT or the CVT Partner plans to use such third party to 
market the Licensed Product.  At Syntex's request, during the Negotiation 
Period the parties will negotiate in good faith to enter into an agreement 
providing for Syntex or an Affiliate of Syntex being granted rights as a 
marketing partner of CVT or the CVT Partner.  Such agreement shall be on 
commercially reasonable terms, which may include, without limitation, 
co-promotion product exchange and other consideration, consistent with 
customary business practices in armslength transactions with third parties in 
the pharmaceutical industry, it being understood that CVT or the CVT Partner 
shall be entitled to reject Syntex's offer at the end of the Negotiation 
Period and seek more favorable terms from a third party.  If no agreement is 
entered into with Syntex or a Syntex Affiliate by the end of the Negotiation 
Period, then CVT or the CVT Partner shall be free to enter into an agreement 
to sublicense a third party at its sole discretion on terms materially more 
favorable to CVT than those last offered by Syntex or its respective 
Affiliate.  "Terms" shall include, but not be limited to, royalty, 
copromotion, product exchange and level of development or marketing support 
for the Licensed Product in question.  If CVT or the CVT Partner intends to 
enter into such an agreement with a third party on terms materially equal or 
less favorable to CVT than those last offered by Syntex or its Affiliate, it 
shall first offer such terms to Syntex or its Affiliate, as the case may be, 
in writing, and Syntex or its Affiliate shall have thirty (30) days from 
receipt of such offer to accept or reject the terms of the offer in its 
entirety.  If Syntex or its Affiliate rejects the offer, CVT or the CVT 
Partner, as the case may be, shall then be free to enter into the agreement 
with such third party or another party upon the offered terms.

reasonable notice by CVT, for ex-Syntex personnel and ex-Syntex consultants, 
as the case may be, to disclose and discuss Syntex's proprietary information 
on the Compound to CVT or the CVT Partner solely in furtherance of the 
purposes of this Agreement.  Syntex will pay up to a maximum total of 
[                    ] for the reasonable costs (including consulting fees 
and reasonable travel expenses), in the aggregate, of all ex-Syntex personnel 
and of the two, [          ]consultants Dr. Gary Lopaschuk and Dr. D.M. 
Turnball when providing the foregoing services to CVT and the CVT Partner, 
and CVT shall be solely responsible for payment of any such costs in excess 
of that amount and the costs of any other consultants of CVT.

            (d)    Syntex's obligations in accordance with this Article III,
including making employees available for telephone consultations,  with respect
to transfer of written information and associated documentation relating to pre-
clinical and

                                         9.

clinical activities and IND matters shall cease [                ] from the
effective date of this Agreement.

    3.2     CVT shall provide periodic progress reports of the significant
results of the development of the Licensed Products and CVT's progress in
meeting the milestone timetable set out in Appendix B, in such form and detail
as Syntex may reasonably require.

    3.3     If Syntex has been granted rights under an agreement pursuant to
Section 2.4 above, it is understood that CVT shall then make available to Syntex
any know-how, information, data, etc. (including the registration file prepared
by CVT or the CVT Partner for registration approval) in CVT's or the CVT
Partner's possession for Syntex's marketing of the Licensed Product in that
portion of the CVT Territory where Syntex has been granted rights to sell
Licensed Product(s).  In such case, the provisions of Section 2.5 shall not
apply to that portion of the CVT Territory where Syntex has been granted rights
to sell Licensed Product(s).

efforts to introduce CVT to the Third Party Licensee.

    4.3     Syntex shall endeavor to provide access by CVT to all consultants
who have been involved in the development of the Compound by Syntex and whom CVT
desires to retain for the purposes of this Agreement, to the extent such
consultants are available and willing to work with CVT.  Subject to
Section 3.1c), all costs and expenses associated with retaining such consultants

efforts to develop the Compound for the treatment of angina pectoris within
milestone/time guidelines set out in Appendix B hereto, or as later mutually
agreed to in writing by duly authorized officers of the parties hereto. CVT
shall notify Syntex before the lapse of a time limit contained in the
milestone/time guidelines that the completion of a particular trial or the
filing of a certain document has been delayed, and if CVT can competently
demonstrate that such delay was due to valid reasons beyond CVT's control and
that CVT has undertaken reasonable efforts to overcome such adverse
circumstances, then in such a case Syntex shall, upon consultation with CVT,
extend the respective time limit for a reasonable period.  Notwithstanding the
foregoing, Syntex shall not be obligated to extend any time limit for reaching a
particular milestone set

milestone in question by such an extended time limit, unless the amount set
forth for payment upon reaching the milestone is paid on or before expiration of
the extended time limit, shall be deemed a material breach of the Agreement by
CVT.

    4.6     Subject to Section 11.4, CVT shall use commercially reasonable
efforts consistent with accepted pharmaceutical business practices and legal
requirements to promote, market, distribute and sell the Licensed Products with

similar market potential.  CVT and any sublicensee of CVT shall launch Licensed
Product(s) in each country of the CVT Territory within [              ] of
receiving marketing approval, or pricing approval if required, whichever is
later, for the Licensed Product in question.

    4.7     With regard to any countries in the CVT Territory for which CVT is
acting through an Affiliate or sublicensee, CVT's Affiliated Company or
sublicensee of CVT, as the case may be, shall observe commercially reasonable
efforts comparable to the ones set forth above.

    4.8     Upon [              ] prior written notice, but in any event not
earlier than [              ] after launch of a Licensed Product in a country in
question, Syntex may convert the right and license granted pursuant to 
Article II into a non-exclusive right and license in a given country of the 
CVT Territory in the event CVT, or the responsible CVT Affiliate or 
sublicensee fails to comply with its obligations in each such country as set 
forth above, unless, within such [               ] period, CVT or the 
responsible CVT Affiliate or sublicensee shall have


                                         12.

<PAGE>

cured such default or shall have put a reasonable plan in place and allocated 
sufficient resources to meet its efforts - obligation in the country in 
question, all to the reasonable satisfaction of Syntex.

authorization) from the relevant authority in each country of the CVT Territory;

            (c)    the date of the first sale of the Licensed Product in each
country of the CVT Territory; and

            (d)    any events which might be material to Syntex in connection
with a possible extension of the patent protection term.  In this regard, CVT
shall cooperate with Syntex in filing for and obtaining patent extensions and
supplementary or complementary protection certificates in any country of the
Territory, if and when available, including supplementary protection
certificates in European Union (EU) countries and European Free Trade Area
(EFTA) countries, patent extensions in the United States of America, and
administrative protection, such as so-called pipeline protection in certain
countries of the CVT Territory.  Such cooperation shall include, without
limitation, providing to Syntex, within one (1) month of receipt by CVT, CVT's
Affiliated Companies, recognized distributors and sublicensees, a copy of every
marketing authorization for


                                         13.

within one (1) month of availability of the document, a copy of the official
journal page from each EU or EFTA country giving the marketing approval number
and date of authorization for each approved Licensed Product, and a summary of
the characteristics of the Licensed Product for that country, for the purpose of
applying for supplementary protection certificates under EEC (European Economic
Community) Directive 1768/2, which Syntex shall have the right to do in its sole
discretion, and providing information and signing of documents as required.

    4.10    As soon as practicable after execution of this Agreement, but in
any event within [                 ] days of the effective date, Syntex shall
initiate transfer of ownership of and responsibility for all the pending
Investigational New Drug applications, IND 30,205 (oral tablets and caps) and
IND 43,735 (sustained-release tablets) ("INDs"), relating to the Compound that
have been filed with the United States Food and Drug Administration ("FDA") by
sending the appropriate communication to the FDA.  Syntex shall render
reasonable assistance with respect to matters dealing with the transfer of the
IND consistent with its obligations in Article III.  After transfer of ownership
of the INDs to CVT, CVT shall be solely responsible for all matters relating to
the INDs.

Patents and Know-How cover the manufacture, use, sale, offer for sale, or import
of the Licensed Product a rate of [                                 ].

            (b)    For sales of a Licensed Product in a country of the CVT
Territory in which competition by products having the same active compound as
the Licensed Product exceeds [                       ] in terms of unit sales,
based on IMS data or equivalent independent survey, a royalty reduced to [
         ] of the rate shown in Section 5.2 (a)  above for as long as such

    5.3     The obligation to pay royalties to Syntex hereunder shall be
imposed only once with respect to the same unit of the Licensed Product.


                                         17.

<PAGE>

    5.4     No royalties shall accrue on the sales of CVT to CVT's Affiliated
Companies or sublicensees of CVT on any transactions between such entities.
Royalties shall accrue only on sales of the Licensed Product from CVT,
Affiliated Companies of CVT or sublicensees of CVT to third parties that are not
Affiliates of those entities.

    5.5     In the event that CVT shall grant a sublicense to a third party,
including, without limitation, the CVT Partner,  all of the terms and conditions
of this Agreement shall apply to such sublicensee to the same extent as they
apply to CVT.  CVT guarantees the performance of all obligations so imposed on
its sublicensees under this Agreement and will itself pay and account to Syntex
for all royalties due under this Agreement which may accrue by reason of the
action or operations of any of CVT's sublicensees.

    5.6     CVT shall pay to Syntex the royalties due hereunder, including any
royalties due from the sales of Licensed Product by CVT's Affiliates or
sublicensees on a quarterly basis, within [            ] of such royalty
computation period, that is to say up to the last working day of the months of [
                                ] respectively of each year.  The royalty shall
be paid to Syntex in U.S. Dollars and computed in accordance with Section 5.7
and Section 5.8, and CVT shall submit to Syntex, together with each royalty
payment, a written royalty statement containing at least the following
information:

royalty (by country);

            (c)    total royalties payable to Syntex (by country); and

            (d)    any relevant information related to matters stated in
Section 5.9.

    Any compensation payment that is not paid on or before the date such
payment is due under this Agreement shall bear interest, to the extent permitted
by applicable law, at the average one month London Interbank Offered Rate
(LIBOR) for the currency and time such a payment is overdue.  The payment of
such interest shall not affect the rights defined in Section 11.3.

    5.7     With respect to each quarter, monthly adjusted gross sales in the
currency of the country of sale will be converted to U.S. Dollars at an exchange
rate that is the average of the daily exchange rate for the U.S. Dollar and the
currency of the country of sale as quoted by The Wall Street Journal, or a
comparable publication acceptable to the parties if it ceases to exist, for the
corresponding month in which the adjusted gross sales are made and then
aggregated in U.S. Dollars for the quarter in question.  From that quarterly
aggregate amount in U.S. Dollars, a lump sum of [               ] shall be
deducted to obtain the Net Sales aggregate amount of the quarter in question.

    5.8     CVT shall keep accurate books and records setting forth the gross
sales, adjusted gross sales, Net Sales, the amount of royalties payable to
Syntex as provided for herein, for each country with regard to the Licensed
Product sold by CVT, CVT's Affiliated Companies or sublicensees of CVT.  Such
books and records shall be retained by CVT at its principal place of business
for at least the three (3) years immediately following the calendar year to
which each shall pertain.  Abstracts thereof shall be made independently from
CVT by CVT's public accountants and shall be made available for audit, all at
the request and expense of Syntex by an independent certified public accountant
or accounting firm appointed by Syntex and acceptable to CVT; provided, however,
that if the

audit on behalf Syntex is conducted at the same time as the regular, annual
audit of CVT, the expense of such audit shall be borne by CVT.  CVT shall not
unreasonably withhold acceptance of an independent certified public accountant
or accounting firm appointed by Syntex.  In the event that such audit shall
indicate that in any calendar year the royalties which should have been paid by
CVT are at least [               ] greater than those which were actually paid
by CVT, then CVT shall pay the cost of such audit.

    5.9     Any tax required to be withheld by CVT under the laws of any
country for the account of Syntex shall be promptly paid by CVT for and on
behalf of Syntex to the appropriate governmental authority, and CVT shall
furnish Syntex with proof of payment of such tax.  Any such tax actually paid on
Syntex's behalf shall be deducted from royalty payments due Syntex.

6.  SUPPLY OF COMPOUND.

    6.1     Subject to (i) existing quantities of bulk Compound, granulated,
formulated Compound and tableted, formulated Compound in Syntex's possession and
(ii) Syntex's commitment to provide certain quantities of such materials to
Syntex's Third Party Licensee, Syntex shall provide to CVT (x) at no charge, any
combination of free goods consisting of bulk Compound, granulated, formulated
Compound and tableted, formulated Compound having a total value of [
                                                  ] as calculated based on the
prices listed on Appendix C hereto, and (y) at CVT's expense, such other agreed
to quantities of bulk Compound, granulated, formulated Compound and tableted,
formulated Compound in Syntex's possession at the prices set forth in Appendix
C.  CVT shall order and complete


                                         20.

<PAGE>


the purchase of the foregoing materials that it desires to purchase and specify
those materials that it wishes to receive as free goods as soon as practicable,
but in no event later that [            ] after the effective date, and Syntex
shall not be obligated to supply any material ordered or specified thereafter.
The materials to be provided hereunder are provided "as is", and Syntex hereby
disclaims any representation or warranty that the materials provided hereunder
will be suitable for use in any manner whatsoever or have adequate dating for
use, including, without limitation, for use in clinical trials, or that such
materials will meet the requirements of any analysis required to establish
extended dating for the materials provided.  In the event that the materials
provided need to be reanalyzed to establish extended dating or for any other
reason, or such materials have to reworked or otherwise manipulated, CVT shall
be solely responsible for all of the costs and expenses associated therewith and
relating thereto.  Title and risk of loss shall pass to CVT upon delivery by
Syntex to a common carrier, F.C.A. (Incoterms, 1990), Syntex's storage facility.
Thereafter, subject to Syntex's obligations under Article III, CVT and the CVT
Partner will be solely responsible to procure the necessary quantities of
Compound for the development and manufacture of the Licensed Product.

    6.2     CVT acknowledges that it has been informed of the existence, 
circumstances and details of a "temporary import bond(s)" put up by Syntex 
with respect to the import of existing Counpound into the United States,
including, without limitation, the fact that Syntex has closed out such 
bond(s) by shipping the Compound out of the United States, and the potential 
consequences of importing any quantity of such Compound into the United 
States.  CVT shall be responsible for and pay any transportation costs, duties,
fines, taxes, penalties, forfeitures or other charges of any kind ("Costs")
associated with the


                                         21.

<PAGE>

supply by Syntex of any Compound pursuant to Section 6.1 and shall indemnify and
hold harmless Syntex and any Syntex Affiliates from any such Costs.  Any costs,
expenses or penalties of any kind associated with the import of any quantity of
the Compound into the United States, whether or not relating to such bond(s),
after the effective date of this Agreement shall be totally included with the
Costs for which the foregoing indemnity and hold harmless apply.

    6.3     Subject to Syntex's obligations under Article III, CVT and the CVT
Partner shall be solely responsible for manufacturing the Compound and Licensed
Products.  CVT shall be entitled to procure from any appropriate source the
Compound necessary to develop and manufacture the Licensed Product for marketing
purposes.

7.  LICENSED PRODUCT LIABILITY/DISCLAIMER OF WARRANTIES.

    7.1     CVT shall indemnify, and holds harmless, Syntex, its Affiliates,
directors, employees and agents from all costs and expenses of any kind,
including reasonable attorneys fees, arising from any claim relating to the use
of the Syntex Know-How and the Syntex Patent Rights, or the use, manufacture,
promotion, marketing and sale of the Compound or any Licensed Products by CVT,
its Affiliates, its sublicensees, distributors and customers.

    7.2     Syntex hereby disclaims any warranties, whether express or implied,
of any kind, including, without limitation, any warranty of merchantability or
fitness for any particular purpose, with respect to any Compound or other
materials in whatever form provided to CVT hereunder, or that the Compound or a
Licensed


                                         22.

<PAGE>


Product can be successfully developed by use of the Syntex Know-How, or that
clinical or commercial quantities of the Compound or Licensed Product can be
produced by use of the Syntex Know-How, or that the Syntex Patent Rights are or
will be valid or can be or will be enforceable, or that the use of the Syntex
Know-How or practice of the invention of the Syntex Patent Rights will not
infringe the intellectual property rights of a third party; provided, however,
that as of the effective date of this Agreement to the best of the knowledge of
Syntex there are no facts that on their face would render the Syntex Patent
Rights invalid or unenforceable and Syntex has received no claims with respect
thereto.

8.  MAINTENANCE AND ENFORCEMENT OF SYNTEX PATENT RIGHTS.

    8.1     Syntex agrees to prosecute and maintain, [
] all of the patents and patent applications included within Syntex Patent
Rights.  At Syntex's request, CVT shall cooperate, in all reasonable ways in
connection with the prosecution of all patent applications included within
Syntex Patent Rights.  Syntex shall advise CVT promptly of any significant
developments in the prosecution of Syntex Patent Rights in the CVT Territory, in
particular of the issuance of or rejection of or of opposition to or of protest
of any patent or application within Syntex Patent Rights.  Should Syntex decide
that it is no longer interested in maintaining or prosecuting Syntex Patent
Rights or part thereof, it shall promptly advise CVT thereof and, at the request
of CVT, Syntex shall assign free of charge such Syntex Patent Rights or part
thereof to CVT.  Upon assignment of such Syntex Patent Rights or part thereof,
CVT will thereafter prosecute and maintain such Syntex Patent Rights [
 ] to the extent that CVT desires to do so.


                                         23.

    8.2     Each party will advise the other promptly upon its becoming aware
of any third party infringement of Syntex Patent Rights. In the event of an
infringement of Syntex Patent Rights by a product that would be or is
competitive with a Licensed Product under active development or being sold by
CVT, the parties agree with the following:

            (a)    to consult with each other to attempt to agree on whether
legal action should be taken against the infringer, and also to establish the
proportion in which they will participate in the costs and expenses of the
action, if taken, and in any recoveries or awards resulting therefrom; and

            (b)    in the event Syntex does not agree to bring suit or to
participate in a suit against any such infringer, CVT shall have the right to
take such action at its own expense and deduct up to [                 ] of its
reasonable litigation expenses from future royalties or milestone payments due
to Syntex, provided that such deduction does not reduce the royalties or
milestone payments payable in any quarter below [                 ] of the
royalties or milestone payments otherwise due in such quarter, and, upon
receiving a recovery or award from such suit, such recovery and award shall be
used first to reimburse CVT for its reasonable litigation expenses actually
incurred, then to reimburse Syntex for the amounts of any unpaid royalties or
milestone payments, and any remainder of the recovery and award shall be
retained by CVT for its own benefit and use; and

            (c)    in any such infringement suit Syntex shall, at the request
of CVT render all reasonable assistance in the prosecution of such suit.


                                         24.

9.  RETAINED RIGHTS.

    Syntex retains all rights to make, have made, use, import, offer to sell,
and sell the Licensed Compounds and to use the know-how encompassed in the
Syntex Patents and Know-How in the CVT Territory for non-Cardiovascular
Indications.  CVT herewith grants to Syntex a non-exclusive, royalty-bearing
right and license in the CVT Territory under any CVT Patents and Know-How to
exercise such rights.  For so long as Syntex is selling any product covered by a
claim of the CVT Patent Rights, Syntex shall pay CVT a royalty equal to [
    ] of Net Sales, as defined in Section 1.10, with respect to sales by Syntex,
its Affiliates or sublicensees; provided, however, that if CVT jointly owns CVT
Patent Rights with a third party and payments would be due such third party upon
Syntex's use of the CVT Patent Rights, the parties shall negotiate in good faith
a commercially reasonable royalty rate that reflects payments due such third
party.

10. CONFIDENTIAL INFORMATION.

    10.1    CVT shall keep the Syntex Know-How in strict confidence and shall
not use Syntex Know-How except for the purposes of this Agreement.  Any
information disclosed pursuant to the Confidentiality Agreement between the
parties dated November 7, 1994 shall be considered Syntex Know-How and governed
by the terms of this Agreement.

    10.2    Both CVT and Syntex agree to keep in strict confidence all other
know-how as well as other information and data of confidential nature received
from the


                                         25.

<PAGE>

other party under this Agreement and not to make any use thereof other than
provided under this Agreement.

    10.3    The confidentiality obligations as per this Article 10 shall not
apply to the extent that the Syntex Know-How or other know-how or information
and data are required by appropriate authorities to be submitted for purposes of
registration of the Licensed Product; provided, however, that to the extent
possible such submissions shall be made on a confidential basis.  The
confidentiality and non-use obligations under this Article 10 shall extend for
the term of this Agreement and five (5) years thereafter.

    10.4    The obligation of confidentiality and non-use as set forth in this
Article 10 shall not apply:

            (a)    to information and data which, at the time of disclosure,
was known by the recipient party or an Affiliated Company, or which after
disclosure was independently developed by the recipient party or an Affiliated
Company without use of such information and data, and which can be so
demonstrated by the records of the recipient party or an Affiliated Company, as
the case may be; and/or

            (b)    are public knowledge at the date of disclosure to the
recipient party; and/or

            (c)    become public knowledge at a later date without any fault of
the recipient party or an Affiliated Company; and/or


                                         26.

<PAGE>

            (d)    are disclosed to the recipient party or an Affiliated
Company by a third-party having the right to do so.

    10.5    Nothing in this Article 10 or this Agreement shall be construed to
prevent either party from disclosing to its Affiliated Companies information and
data obtained from the other party during this Agreement, provided that such
information is used in a manner consistent with this Agreement, and further
provided that said Affiliated Companies are bound by a like confidentiality
obligation with respect to such information.

11. TERM AND TERMINATION.

    11.1    This Agreement shall be effective as of the date first written
above.

    11.2    This Agreement shall have a duration on a country-by-country and
product-by-product basis of the later of (i) ten (10) years from the date of
first commercial sale of the Licensed Product in a given country of the CVT
Territory or (ii) a duration corresponding to the duration of the Syntex Patent
Rights having one or more claims covering a Licensed Product, or its use or
manufacture, in a given country, whichever is longer.  Following expiration of
the term as set forth above, CVT shall retain a non-exclusive, fully-paid
license under the Syntex Know-How to manufacture, use, sell and offer for sale
Licensed Products for Cardiovascular Indications within the CVT Territory.

    11.3    Failures by one party to comply with any of its respective
obligations contained in this Agreement shall entitle the other party to give
the party in default written notice of such default.  If such default is not
remedied within [      ]


                                         27.

<PAGE>

after receipt of such notice (or thirty (30) days in the event of
non-payment), the notifying party shall be entitled to terminate this Agreement
by giving notice with immediate effect.  The right of either party to terminate
this Agreement as provided hereinabove shall not be affected in any way by its
waiver of or failure to take actions with respect to any previous default.  In
such cases of breach by CVT, all licenses from CVT to Syntex as set forth below
in Section 11.4  for the case of an early termination shall be royalty free, and
CVT shall provide to Syntex all of the information required by Section 11.4 in
the event of early termination or breach of this Agreement by CVT.  If there is
any BONA FIDE dispute between the parties regarding the right of termination
based on failure by CVT to make a milestone or royalty payment when due, the
disputed milestone or royalty payment, as the case may be, shall be paid into an
interest bearing account by CVT where it shall remain during the pendency of the
dispute, and upon resolution of the dispute, paid, with accumulated interest, to
the prevailing party.

    11.4    CVT shall have the right to terminate the Agreement at any time 
provided that CVT gives notice to Syntex at least one hundred and twenty 
(120) days prior to such termination and under the condition that CVT further 
informs Syntex together with the notice of termination that, in its 
reasonable business judgment based on scientific, medical, economic or other 
valid business reasons, CVT has determined not  to carry out further 
development or marketing of the Licensed Products. In the event of such an 
early termination, the licenses granted hereunder by Syntex shall revert to 
Syntex. In addition, CVT shall grant Syntex an exclusive license, with the 
right to sublicense, to the CVT Patents and Know-How directly related to and 
solely usable in connection with the Compound and the Licensed Products to 
make, have made, use,


                                         28.

<PAGE>


import, offer to sell and sell the Compound and the Licensed Products. All other
CVT Patents and Know-How shall be licensed non-exclusively to Syntex solely for
use in connection with the Licensed Products as set forth above. Licenses under
the CVT Patents shall be royalty bearing on commercially reasonable terms not to
exceed, in the aggregate, [      ] of Net Sales, as defined in Section 1.10,
with respect to sales by Syntex, its Affiliates or sublicensees, of Licensed
Products.  All CVT Know-How in CVT's possession or under its control relating to
the Licensed Products including without limitation the documents necessary to
obtain or maintain the registration authorization of the relevant authorities in
the CVT Territory, shall be made available to Syntex free of charge.

    11.5    This Agreement shall survive the acquisition or change of control
of either company, provided that in the case of CVT the acquiring entity will
expressly assume all rights and obligations contained in this Agreement and such
entity further undertakes to use its commercially reasonable efforts consistent
with accepted pharmaceutical business practices and legal requirements to
promote, market, distribute and sell the Licensed Products with the same
standard of effort as used in the marketing of its own products of similar
market potential.

    11.6    In the event of a conversion of the exclusive right and license of
CVT into a non-exclusive right and license because of a failure of CVT to comply
with its efforts obligation pursuant to Section 4.3, the provisions of Section
11.4 for early termination by CVT shall apply MUTATIS MUTANDIS, with the
exception that Syntex shall receive a royalty-free, non-exclusive license.


                                         29.

<PAGE>

    11.7    Neither of the undersigned parties shall be liable for failure to 
perform its obligations under this Agreement, where such failure was 
occasioned by contingencies beyond its control, including without limitation, 
strikes or work stoppages, lock-outs, riots, wars, delay of carriers, Acts of 
God, including without limitation, fire, floods, storms, and earthquakes, 
acts or failures to act by government or governmental agencies or 
instrumentalities (Force Majeure).  Each party will notify the other 
immediately, should any such contingencies occur.  Such notice shall set 
forth the obligations that the notifying party is unable to perform and shall 
also specify the contingencies which it contends provide a basis under this 
Section 11.7 for such non-performance.  Nothing herein shall relieve a party 
from the obligation to pay promptly, in U.S. dollars, all payments that may 
be due under this Agreement.

    11.8    In the event of termination of the licenses to CVT, any licenses
granted to a CVT Partner shall survive and this Agreement may be assumed by the
CVT Partner for the CVT Partner's portion of the CVT Territory, subject to
adequate assurances to Syntex of such CVT  Partner's ability to perform CVT's
obligations hereunder.  The agreement between CVT and the CVT Partner shall
provide that if this Agreement is not assumed by the CVT Partner, then the
agreement between CVT and the CVT Partner shall be terminated and the CVT
Partner's patent rights and know-how relating to the Licensed Products will be
licensed to Syntex, with the right to sublicense, with delivery of the necessary
information to enable Syntex to exercise the license and continue the
development, marketing and sale of Licensed Products in the CVT Partner's
portion of the CVT Territory under the same terms as Syntex's license to the CVT
Patents and Know-How pursuant to Section 11.4 as in the case of CVT's
termination; provided, however, that if the CVT Partner has acquired


                                         30.

<PAGE>

technology from a third party that the CVT Partner is not permitted to transfer
to Syntex, then there would not be an obligation on CVT to obtain agreement to
license such technology.  In such event, CVT and the CVT Partner will render
reasonable assistance to Syntex in its attempts to obtain access to that third
party technology.  Furthermore, should CVT have acquired licenses from third
parties under technology relating to Licensed Products for which CVT has the
right to sublicense, CVT shall grant sublicenses to Syntex upon the same
financial terms as CVT's licenses, unless the licenses are available from the
third party directly to Syntex on the same or more favorable financial terms.

    11.9    Either party shall have the right to terminate this Agreement if
the other party becomes insolvent or unable to pay its debts or perform its
obligations as they mature, or makes an assignment for the benefit of creditors,
or is the subject of a petition or other document seeking relief under any
bankruptcy law, filed by or against a party, that is not discharged with
prejudice within sixty (60) days thereafter, such termination to be effective
upon the delivery of written notice to the insolvent or bankruptcy party.


12. MISCELLANEOUS.

    12.1    CVT shall not assign or transfer, in whole or in part, this
Agreement or any rights thereunder without the prior written consent of Syntex.

    12.2    In the event of the permitted assignment or transfer by CVT of this
Agreement or any part thereof, or in the event of any sublicense granted by CVT,
the assignee, transferee or sublicensee shall agree to be bound by the terms of
this Agreement and CVT shall guarantee the performance and obligations thereof.


                                         31.

<PAGE>

    12.3    Syntex shall have the right to assign or transfer, in whole or in
part, this Agreement or any rights thereunder, or delegate any of its
obligations, to any Affiliate of Syntex and such Affiliate shall agree to be
bound by the terms and conditions of this Agreement, and Syntex shall guarantee
the performance and obligations thereof.  Promptly after any such assignment or
transfer, Syntex shall provide CVT with written notice of the assignment or
transfer and the identity of the assignee or transferee.

    12.4    This Agreement contains the entire understanding between the
parties relating to the subject matter hereof and supersedes any and all prior
agreements, understandings and arrangements, whether written or oral, between
the parties, including the Confidentiality Agreement dated November 7, 1994 and
the Heads of Agreement dated December 21, 1995.  No amendments, changes,
modifications or alterations of the terms and conditions of this Agreement shall
be binding upon either party hereto unless in writing and signed by both
parties.

    12.5    All titles and captions in this Agreement are for convenience only
and shall not be interpreted as having any substantive meaning.

    12.6    Both parties hereby expressly state that it is the intention of
neither party to violate any rule, law and regulations.  If any of the
provisions of this Agreement are held to be void or unenforceable, then such
void or unenforceable provisions shall be replaced by valid and enforceable
provisions which will achieve as far as possible the economic business
intentions of the parties.

    12.7    Unless required by law or regulation, each party shall refrain from
making any public announcement or disclosure of the terms and conditions of this


                                         32.

<PAGE>


Agreement without the prior written consent of the other party, which consent
shall not unreasonably be withheld; provided, however, CVT may publicize certain
aspects of the Agreement at time of signing, subject to prior written approval
by Syntex.

    12.8    No failure or delay on the part of a party in exercising any right
hereunder shall operate as a waiver of, or impair, any such right.  No single or
partial exercise of any such right shall preclude any other or further exercise
thereof or the exercise of any other right.  Any waiver on the part of either
party hereto of any right hereunder shall be effective only if made in writing
and shall not constitute or imply a waiver of any other right or a subsequent
waiver.

    12.9    The indemnities of Section 2.5, Section 6.2 and Section 7.1 and the
provisions of Section 5.6, Section 5.7 (for one year), Article X (for the term
set forth in Section 10.3), Section 11.4 and Article XIV shall survive
termination or expiration of this Agreement.

Purchasers, attached hereto as EXHIBIT A.

                                    AGREEMENT

     In consideration of the mutual promises, representations, warranties and
conditions set forth in the Agreement, the Company and each Purchaser, severally
and not jointly, agrees as follows:

1.   AGREEMENT TO SELL AND PURCHASE.

     1.1  AUTHORIZATION OF THE SHARES AND WARRANTS.  The Company has authorized,
or before the Closing, as defined in paragraph 2.1 hereof, will have authorized,
the issuance and sale of: (a) up to 5,000,000 shares of its Series E Preferred
Stock (the "Shares") and (b) warrants (the "Warrants") to purchase up to
2,500,000 shares of the Company's Series E Preferred Stock with an exercise
price of $2.00 per share (the "Warrant Shares"), at a purchase price of $2.00
per Share and Warrant Share (a "Unit").  As used herein, a Unit is comprised of
one share of Series E Preferred Stock and one Warrant, in substantially the form
set forth in EXHIBIT B hereto, to purchase one-half of a share of Series E
Preferred Stock.

     1.2  SALE OF SHARES AND WARRANTS.  In reliance upon the Purchasers'
representations and warranties contained in Section 4 hereof and subject to the
terms and conditions set forth herein, the Company hereby agrees to sell to each
Purchaser, at a price per Unit of $2.00, the aggregate number of Shares and
Warrants set forth below such Purchaser's signature on such Purchaser's
signature page hereto.  The total amount of common stock of the Company (the
"Common Stock") and other securities issuable upon conversion of the Shares and
the Warrant Shares is hereinafter referred to as the "Conversion Stock."  The
Shares, Warrants, Warrant Shares and the Conversion Stock are hereinafter
collectively referred to as the "Securities."

     1.3  PURCHASE OF SHARES AND WARRANTS.  In reliance upon the representations
and warranties of the Company contained herein, and subject to the terms and
conditions set forth herein, each Purchaser hereby agrees to purchase, at a
price per Unit of $2.00, the number of Shares and Warrants set forth below such
Purchaser's signature on such Purchaser's signature page hereto.  Each

<PAGE>

Purchaser shall, severally and not jointly, be liable for only the purchase of
the Shares and the Warrants indicated on such Purchaser's signature page hereto.

     1.4  FURTHER ISSUANCE.  The Purchasers agree that the Company shall be
entitled to issue and sell any shares of Series E Preferred Stock (or securities
convertible into Series E Preferred Stock) not previously issued and sold at the
Closings (as hereinafter defined), in connection with any corporate partnering,
collaboration, lease financing or similar transaction.

2.   CLOSING DATE; DELIVERY.

     2.1  CLOSING DATE.  The first closing for the purchase and sale of the
Units hereunder will be on September 8, 1995 (the "First Closing") at the
offices of Cooley Godward Castro Huddleson & Tatum, Five Palo Alto Square, Palo
Alto, California 94306, or at such other time and place as the Company and the
Purchasers shall agree upon (the "First Closing Date").  Additional closings
("Additional Closings") may be held from time to time following the First
Closing and on or before October 31, 1995 at such time (a "Closing Date") and
place as the Company may elect.  At or prior to any such Additional Closing, the
Purchaser or Purchasers at such Additional Closing shall execute counterpart
copies of this Agreement and any related agreements or other documents required
to be executed hereunder, dated as of the date of such Additional Closing, and
shall thereupon become parties hereto and thereto for all purposes and be added
to the Schedule of Purchasers.  The First Closing and any Additional Closing
shall be referred to collectively as the "Closings" and singularly as a
"Closing."

     2.2  DELIVERY.  At each Closing, the Company will deliver to each Purchaser
a stock  certificate and a Warrant registered in such Purchaser's name
representing the number of Shares and Warrants, respectively, purchased by such
Purchaser as set forth on such Purchaser's signature page hereto.  At each
Closing, each Purchaser will pay the purchase price, in an amount equal to $2.00
times the number of Units being purchased by such Purchaser, by check, wire
transfer, cancellation of indebtedness, or a combination thereof, at the option
of the Purchaser.  No Warrants will be issued for fractional shares.

     2.3  SUBSEQUENT CHANGE IN TERMS.  If, after the First Closing, the Company
shall sell any of the Units at any Additional Closing upon terms more beneficial
to the Purchasers than those at any previous Closing, then the Company shall
offer such terms to the Purchasers from any previous Closing and shall take
appropriate actions to amend any document or agreement to carry out this
covenant.

action on the part of Purchaser for the authorization, execution, delivery and
performance by Purchaser of this Agreement and the Investor Rights Agreement has

          (b)  INVESTMENT INTENT.  Purchaser is acquiring the Shares and the

                                        8

<PAGE>

been registered under the Act by reason of a specific exemption from the
registration provisions of the Act which depends upon, among other things, the
bona fide nature of the investment intent as expressed herein.

          (c)  RESTRICTED SECURITIES.  Purchaser acknowledges that the
Securities must be held indefinitely unless subsequently registered under the
Securities Act or an exemption from such registration is available.  The
Purchaser is aware of the provisions of Rule 144 promulgated under the
Securities Act which permits limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, in case
the Purchaser has held the Securities for less than three years or is an
affiliate of the Company, among other things: the availability of certain
current public information about the Company, the resale occurring not less than
two years after the Securities were purchased from the Company or an affiliate
of the Company, the sale being through a "broker's transaction" or in
transactions directly with a "market maker," and the number of shares being sold
during any three-month period not exceeding specified limitations.

          (d)  NO PUBLIC MARKET.  Purchaser understands that no public market
now exists for any of the securities issued by the Company and there can be no
assurance that a public market will ever exist for the Securities.

          (e)  RECEIPT OF AND ACCESS TO INFORMATION.  Purchaser has been
furnished with such materials and has been given access to such information
relating to the Company as it or its qualified representative has requested and
has been afforded the opportunity to ask questions regarding the Company and the
Shares and Warrants, all as Purchaser has found necessary to make an informed
investment decision.

     4.2  LEGENDS.  Each certificate representing the Securities shall be
endorsed with the following legend (in addition to any legend required by
applicable state securities laws):

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
     "SECURITIES ACT"), AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR
     HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER
     THE SECURITIES ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
     ACCORDANCE WITH RULE 144 OR ITS SUCCESSOR RULE UNDER THE SECURITIES
     ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL SATISFACTORY TO THE
     COMPANY THAT AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

The Company will not register a transfer of the Securities unless the conditions
specified in the foregoing legend are satisfied, and the Company may instruct
its transfer agent not to register the transfer of any of the Securities unless
the conditions specified in the foregoing legend are satisfied.  Notwithstanding
the foregoing, the Company shall not require a Purchaser to furnish an opinion
of its counsel in connection with a proposed transfer of Securities to a partner
of the Purchaser unless, in the

                                        9

10. TERM AND TERMINATION

    10.1  TERM OF AGREEMENT

    This Agreement shall commence as of the EFFECTIVE DATE and, unless sooner
terminated as provided herein, shall continue in effect until the expiration of
the last to expire CVT PATENT licensed under this Agreement or after ten (10) 
year's marketing of the first PRODUCT [                ] according to Art. 4.4,
whichever is later.

    10.2  TERMINATION AT BAYER'S DISCRETION

    Giving 30 (thirty) days written notice to CVT, BAYER may terminate this
Agreement for any reason in its sole discretion, at any time, especially if 
there is no exclusivity according to Article 4.5 and/or according to Article 
2.2.2.

    BAYER may invite CVT to discuss BAYER's reasons for its intent to 
terminate the Agreement and to allow CVT to give scientific and/or technical 
input to avoid such termination.

    Upon termination of the activities by BAYER, CVT would like to have a 
royalty-bearing grant-back option.  Terms for this would be negotiable in 
good faith, at due time, taking into account the relative contribution of 
BAYER and CVT.  Any such grant-back should also allow BAYER the first right
to negotiate for products based on BAYER's activities under this Agreement
which may subsequently be developed by CVT or a partner of CVT.
