                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
    The enclosed proxy is solicited on behalf of the Board of Directors of CV
Therapeutics, Inc., a Delaware corporation (the "Company"), for use at the
Annual Meeting of Stockholders to be held on June 9, 1998, at 9:00 a.m. local
time (the "Annual Meeting"), or at any adjournment or postponement thereof, for
the purposes set forth herein and in the accompanying Notice of Annual Meeting.
The Annual Meeting will be held at the Company's offices, 3172 Porter Drive,
Palo Alto, California 94304. The Company intends to mail this proxy statement
and accompanying proxy card on or about April 29, 1998, to all stockholders
entitled to vote at the Annual Meeting.
 
SOLICITATION
 
    The Company will bear the entire cost of solicitation of proxies, including
preparation, assembly, printing and mailing of this proxy statement, the proxy
and any additional information furnished to stockholders. Copies of solicitation
materials will be furnished to banks, brokerage houses, fiduciaries and
custodians holding in their names shares of Common Stock beneficially owned by
others to forward to such beneficial owners. The Company may reimburse persons
representing beneficial owners of Common Stock for their costs of forwarding
solicitation materials to such beneficial owners. Original solicitation of
proxies by mail may be supplemented by telephone, telegram or personal
solicitation by directors, officers or other regular employees of the Company.
No additional compensation will be paid to directors, officers or other regular
employees for such services.
 
VOTING RIGHTS AND OUTSTANDING SHARES
 
    Only holders of record of Common Stock at the close of business on April 13,
1998 will be entitled to notice of and to vote at the Annual Meeting. At the
close of business on April 13, 1998, the Company had outstanding and entitled to
vote 11,054,411 shares of Common Stock.
 
    Each holder of record of Common Stock on such date will be entitled to one
vote for each share held on all matters to be voted upon at the Annual Meeting.
 
    All votes will be tabulated by the inspector of election appointed for the
meeting, who will separately tabulate affirmative and negative votes,
abstentions and broker non-votes. Abstentions will be counted towards the
tabulation of votes cast on proposals presented to the stockholders and will
have the same effect as negative votes. Broker non-votes are counted towards a
quorum, but are not counted for any purpose in determining whether a matter has
been approved.
<PAGE>
REVOCABILITY OF PROXIES
 
    Any person giving a proxy pursuant to this solicitation has the power to
revoke it at any time before it is voted. It may be revoked by filing with the
Secretary of the Company at the Company's principal executive office, 3172
Porter Drive, Palo Alto, California 94304, a written notice of revocation or a
duly executed proxy bearing a later date, or it may be revoked by attending the
meeting and voting in person. Attendance at the meeting will not, by itself,
revoke a proxy.
 
SHAREHOLDER PROPOSALS
 
    Proposals of stockholders that are intended to be presented at the Company's
1999 Annual Meeting of Stockholders must be received by the Company not later
than December 18, 1998 in order to be included in the proxy statement and proxy

Company's By-laws, which contain additional requirements with respect to advance
notice of stockholder proposals and director nominations.

                                   PROPOSAL 1
                             ELECTION OF DIRECTORS
 
    The Company's Amended and Restated Certificate of Incorporation and By-laws
provide that the Board of Directors shall be divided into three classes, with
each class having a three-year term. Except as otherwise provided by law,
vacancies on the Board shall be filled only by the affirmative vote of a
majority of the directors then in office, even though less than a quorum of the
Board of Directors, and not by the stockholders, unless the Board of Directors
determines by resolution that any such vacancies shall be filled by the
stockholders. A director elected by the Board to fill a vacancy (including a
vacancy created by an increase in the Board of Directors) shall serve for the
remainder of the full term of the class of directors in which the vacancy
occurred and until such director's successor is elected and qualified.
 
    The Board of Directors is presently composed of eight members. There were
three directors in the class whose term of office expires in 1998. However, one
of the three directors, Samuel D. Colella, has decided not to stand for
re-election in 1998. The Board has reduced the authorized number of directors to
be effective upon the date of the stockholders meeting. Accordingly, there are
two nominees for election to this class. Each of the nominees for election to
this class is currently a director of the Company who was previously elected by
the stockholders. If elected at the Annual Meeting, each of the nominees would
serve until the 2001 annual meeting and until his or her successor is elected
and has qualified, or until such director's earlier death, resignation or
removal.
 
    Directors are elected by a plurality of the votes present in person or
represented by proxy and entitled to vote at the meeting. Shares represented by
executed proxies will be voted, if authority to do so is not withheld, for the
election of the two nominees named below. In the event that any nominee should
be unavailable for election as a result of an unexpected occurrence, such shares
will be voted for the election of such substitute nominee as management may
propose. Each person nominated for election has agreed to serve if elected, and
management has no reason to believe that any nominee will be unable to serve.
 
    Set forth below is biographical information for each person nominated and
each person whose term of office as a director will continue after the Annual
Meeting.

    During the fiscal year ended December 31, 1997, the Board of Directors held

    The Compensation Committee makes recommendations concerning salaries and
incentive compensation for employees, awards stock options to employees and
consultants under the Company's stock option plans and otherwise determines
compensation levels and performs such other functions regarding compensation as
the Board may delegate. During the fiscal year ended December 31, 1997, it met

                                   PROPOSAL 2
               APPROVAL OF 1994 EQUITY INCENTIVE PLAN, AS AMENDED
 
    The Company's 1994 Equity Incentive Plan (the "Incentive Plan") was adopted
by the Board of Directors in February 1994 and approved by the stockholders in
March 1994. As a result of a series of amendments, as of November 17, 1997,
there were 800,000 shares reserved for issuance under the Incentive Plan.
 
    As of November 17, 1997, options (net of cancelled or expired options)
covering an aggregate of 766,443 shares had been granted under the Incentive
Plan and only 33,557 shares (plus any shares that might in the future be
returned to the Incentive Plan as a result of cancellations or expiration of
options) remained available for future grant under the Plan. In November 1997,
the Board approved an amendment to the Incentive Plan, subject to stockholder
approval, to increase the number of shares authorized for issuance under the
Incentive Plan from 800,000 shares to 1,800,000 shares. This amendment is
intended to afford the Company greater flexibility in providing employees with
stock incentives and ensures that the Company can continue to provide such
incentives at levels determined appropriate by the Board.
 
    Stockholders are requested in this Proposal 2 to approve the Incentive Plan,
as amended. The affirmative vote of the holders of a majority of the shares
present in person or represented by proxy and entitled to vote will be required
to approve the Incentive Plan, as amended. Abstentions will be counted toward
the tabulation of votes cast on proposals presented to the stockholders and will
have the same effect as negative votes. Broker non-votes are counted towards a
quorum, but are not counted for any purpose in determining whether this matter
has been approved.
 
                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 2.
 
    The essential features of the Incentive Plan, as amended, are outlined
below:
 
GENERAL
 
    The Incentive Plan provides for the grant of incentive stock options, stock
appreciation rights, nonstatutory stock options, stock bonuses and restricted
stock purchase awards (collectively "Stock Awards"). Incentive stock options
granted under the Incentive Plan are intended to qualify as "incentive stock
options" within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"). Nonstatutory stock options granted under the Incentive
Plan are intended not to qualify as incentive stock options under the Code. See
"Federal Income Tax Information" for a discussion of the tax treatment of
incentive and nonstatutory stock options. Stock appreciation rights granted
under the Incentive Plan may be tandem rights, concurrent rights or independent
rights.
 
PURPOSE
 
    The Incentive Plan provides a means by which employees and directors of and
consultants to the Company and its affiliates could be given an opportunity to
purchase stock in the Company, to assist in retaining the services of employees
holding key positions, to secure and retain the services of persons capable of
filling such positions and to provide incentives for such persons to exert
maximum efforts for the success of the Company. As of March 16, 1998 all of the
Company's approximately 70 employees, directors and consultants are eligible to
participate in the Incentive Plan.
 
ADMINISTRATION
 
    The Incentive Plan is administered by the Board of Directors of the Company.
The Board has the power to construe and interpret the Incentive Plan and,
subject to the provisions of the Incentive Plan, to determine the persons to
whom and the dates on which Stock Awards will be granted, the number of
 
                                       6
<PAGE>
shares to be subject to the Stock Award, the time or times during the term of
each Stock Award within which all or a portion of such Stock Award may be
exercised, the exercise price, the type of consideration and other terms of the
Stock Award. The Board of Directors is authorized to delegate administration of
the Incentive Plan to a committee of one or more members of the Board. In the
discretion of the Board, a committee may consist solely of two or more outside
directors in accordance with Code Section 162(m), or solely of two or more
non-employee directors. The Board has delegated administration of the Incentive
Plan to the Compensation Committee of the Board. As used herein with respect to
the Incentive Plan, the "Board" refers to the Compensation Committee as well as
to the Board of Directors itself.
 
ELIGIBILITY
 
    Incentive stock options and stock appreciation rights appurtenant thereto
may be granted under the Incentive Plan only to employees (including officers
and employee-directors) of the Company and its affiliates. Employees (including
officers), directors and consultants are eligible to receive Stock Awards other
than incentive stock options and stock appreciation rights appurtenant thereto.
 
    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 appurtenant
thereto covering more than 100,000 shares of Common Stock per calendar year.
 
STOCK SUBJECT TO THE INCENTIVE PLAN
 
    If any Stock Award granted under the Incentive Plan expires or otherwise
terminates in whole or in part without having been exercised in full (or vested
in the case of restricted stock), the Common Stock not purchased under such
Stock Award will revert to and again become available for issuance under the
Incentive Plan. Shares of stock subject to exercised stock appreciation rights
shall not again become available for issuance under the Incentive Plan.
 
TERMS OF OPTIONS
 
    The following is a description of the permissible terms of options under the
Incentive Plan. Individual option grants may be more restrictive as to any or
all of the permissible terms described below.
 
    EXERCISE PRICE; PAYMENT.  The exercise price for an incentive stock option
cannot be less than 100% of the fair market value of the Common Stock on the
date of the option grant and the exercise price for a nonstatutory stock option
cannot be less than 85% of the fair market value of the Common Stock on the date
of option grant. At March 16, 1998, the closing price of the Company's Common
Stock as reported on the Nasdaq National Market System was $9.75 per share.
 
    The exercise price of options granted under the Incentive Plan must be paid
either: (a) in cash at the time the option is exercised; or (b) at the
discretion of the Board, (i) by delivery of other Common Stock of the Company,
(ii) pursuant to a deferred payment or other arrangement, or (iii) in any other
form of legal consideration acceptable to the Board.
 
    EXERCISE/VESTING.  Options granted under the Incentive Plan may become
exercisable in cumulative increments ("vest") as determined by the Board. Shares
of stock covered by currently outstanding options under the Incentive Plan
typically vest at the rate of 1/50th per month (24% per year) during the
optionee's
 
                                       7
<PAGE>
employment or services as a director or consultant. Shares covered by options
granted in the future under the Incentive Plan may be subject to different
vesting terms. The Board has the power to accelerate the time during which an
option may be exercised. In addition, options granted under the Incentive Plan
may permit exercise prior to vesting, but 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. To the extent provided by
the terms of an option, an optionee may satisfy any federal, state or local tax
withholding obligation relating to the exercise of such option by a cash payment
upon exercise, by authorizing the Company to withhold a portion of the stock
otherwise issuable to the optionee, by delivering already-owned and unencumbered
stock of the Company or by a combination of these means.
 
    TERM.  The maximum term of options under the Incentive Plan is 10 years. 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 by their terms).
 
    RESTRICTIONS ON TRANSFER.  No stock option may be transferred by the
optionee other than by will or the laws of descent or distribution, provided
that 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. In addition, shares
subject to repurchase by the Company under an early exercise stock purchase
agreement may be subject to restrictions on transfer which the Board deems
appropriate.
 
TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK
 
    PAYMENT.  The purchase price under a restricted stock purchase agreement
shall be such amount as the Board shall determine and designate in such
agreement, however, stock bonuses may be awarded in consideration of past
services without a purchase payment.
 
    The purchase price of stock acquired pursuant to a restricted stock purchase
agreement under the Incentive Plan must be paid either (a) in cash at the time
of purchase; (b) at the discretion of the Board, according to a deferred payment
or other arrangement; or (c) in any other form of legal consideration acceptable
to the Board. The Board may award stock pursuant to a stock bonus agreement in
consideration for past services actually rendered to the Company or for its
benefit.
 
    VESTING.  Shares of stock sold or awarded under the Incentive Plan may, but
need not be, subject to a repurchase option in favor of the Company in
accordance with a vesting schedule as determined by the Board. The Board has the
power to accelerate the vesting of stock acquired pursuant to a restricted stock
purchase agreement under the Incentive Plan.
 
    RESTRICTIONS ON TRANSFER.  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
 
    The Board may grant stock appreciation rights to employees or directors of,
or consultants to, the Company or its affiliates. The Incentive Plan authorizes
three types of stock appreciation rights.
 
    TANDEM STOCK APPRECIATION RIGHTS.  Tandem stock appreciation rights are tied
to an underlying option and require the holder to elect whether to exercise the
underlying option or to surrender the option for an appreciation distribution
equal to the market price of the vested shares purchasable under the surrendered
 
                                       8
<PAGE>
option less the aggregate exercise price payable for such shares. Appreciation
distributions payable upon exercise of tandem stock appreciation rights must be
made in cash.
 
    CONCURRENT STOCK APPRECIATION RIGHTS.  Concurrent stock appreciation rights
are tied to an underlying option and are exercised automatically at the same
time the underlying option is exercised. The holder receives an appreciation
distribution equal to the market price of the vested shares purchased under the
option less the aggregate exercise price payable for such shares. Appreciation
distributions payable upon exercise of concurrent stock appreciation rights must
be made in cash.
 
    INDEPENDENT STOCK APPRECIATION RIGHTS.  Independent stock appreciation
rights are granted independently of any option and entitle the holder to receive
upon exercise an appreciation distribution equal to the market price of a number
of shares equal to the number of share equivalents to which the holder is vested
under the independent stock appreciation right less the fair market value of
such number of shares of stock on the date of grant of the independent stock
appreciation rights. Appreciation distributions payable upon exercise of
independent stock appreciation rights may, at the Board's discretion, be made in
cash, in shares of the Common Stock or a combination thereof.
 
ADJUSTMENT PROVISIONS
 
    If there is any change in the stock subject to the Incentive Plan or subject
to any Stock Award granted under the Incentive Plan (through merger,
consolidation, reorganization, recapitalization, stock dividend, dividend in
property other than cash, stock split, liquidating dividend, combination of
shares, exchange of shares, change in corporate structure or otherwise), the
Incentive Plan and Stock Awards outstanding thereunder will be appropriately
adjusted as to the class and the maximum number of shares subject to such plan
and the class, number of shares and price per share of stock subject to such
outstanding Stock Awards.
 
EFFECT OF CERTAIN CORPORATE EVENTS
 
    The Incentive Plan provides that, in the event of a specified type of merger
or other corporate reorganization which is not approved by the Board, each
outstanding Option under the Incentive Plan shall become fully vested, and the
Company's right of repurchase shall lapse with respect to shares received upon
exercise of an Option prior to full vesting, notwithstanding the terms of the
Option or any early exercise stock purchase agreement, immediately prior to the
consummation of such merger or other corporate reorganization. The Incentive
Plan further provides that, to the extent permitted by law, any surviving
corporation will be required to either assume Stock Awards outstanding under the
Incentive Plan or substitute similar Stock Awards for those outstanding under
such plan, or such outstanding Stock Awards will continue in full force and
effect. In the event that any surviving corporation declines to assume or
continue Stock Awards outstanding under the Incentive Plan, or to substitute
similar options, then the time during which such Stock Awards may be exercised
will be accelerated and the Stock Awards terminated if not exercised during such
time. The acceleration of an Stock Award in the event of an acquisition or
similar corporate event may be viewed as an antitakeover provision, which may
have the effect of discouraging a proposal to acquire or otherwise obtain
control of the Company.
 
DURATION, AMENDMENT AND TERMINATION
 
    The Board may suspend or terminate the Incentive Plan without stockholder
approval or ratification at any time or from time to time. The Incentive Plan
will terminate in September 2006 unless sooner terminated by the Board of
Directors.
 
    The Board may also amend the Incentive Plan at any time or from time to
time. However, no amendment will be effective unless approved by the
stockholders of the Company within twelve months before or after its adoption by
the Board if the stockholder approval of the amendment is necessary for the
Incentive Plan to satisfy the requirements of Section 422 of the Code, Rule
16b-3 of the Securities
 
                                       9
<PAGE>
Exchange Act of 1934, as amended (the "Exchange Act") or any Nasdaq or
securities exchange listing requirements. The Board may submit any other
amendment to the Incentive Plan for stockholder approval, including, but not
limited to, amendments intended to satisfy the requirements of Section 162(m) of
the Code regarding the exclusion of performance-based compensation from the
limitation on the deductibility of compensation paid to certain employees.
 
FEDERAL INCOME TAX INFORMATION
 
    INCENTIVE STOCK OPTIONS.  Incentive stock options under the Incentive Plan
are intended to be eligible for the favorable federal income tax treatment
accorded "incentive stock options" under the Code.
 
    There generally are no federal income tax consequences to the optionee or
the Company by reason of the grant or exercise of an incentive stock option.
However, the exercise of an incentive stock option may increase the optionee's
alternative minimum tax liability, if any.
 
    If an optionee holds stock acquired through exercise of an incentive stock
option for at least two years from the date on which the option is granted and
at least one year from the date on which the shares are transferred to the
optionee upon exercise of the option, any gain or loss on a disposition of such
stock will be a mid-term or long-term capital gain or loss. Generally, if the
optionee disposes of the stock before the expiration of either of these holding
periods (a "disqualifying disposition"), at the time of disposition, the
optionee will realize taxable ordinary income equal to the lesser of (a) the
excess of the stock's fair market value on the date of exercise over the
exercise price, or (b) the optionee's actual gain, if any, on the purchase and
sale. The optionee's additional gain, or any loss, upon the disqualifying
disposition will be a capital gain or loss, which will be long-term, mid-term or
short-term depending on how long the optionee holds the stock. Capital gains are
generally subject to lower tax rates than ordinary income. Slightly different
rules may apply to optionees who are subject to Section 16 of the Exchange Act
or who acquire stock subject to certain repurchase options.
 
    To the extent the optionee recognizes ordinary income by reason of a
disqualifying disposition, the Company will generally be entitled (subject to
the requirement of reasonableness, Section 162(m) of the Code and the
satisfaction of a tax reporting obligation) to a corresponding business expense
deduction in the tax year in which the disqualifying disposition occurs,
provided, however, that options to purchase Common Stock granted to certain
executive officers in 1997 may not be eligible for such treatment.
 
    NONSTATUTORY STOCK OPTIONS.  Nonstatutory stock options granted under the
Incentive Plan generally have the following federal income tax consequences:
 
    There are no tax consequences to the optionee or the Company by reason of
the grant of a nonstatutory stock option. Upon exercise of a nonstatutory stock
option, the optionee normally will recognize taxable ordinary income equal to
the excess of the stock's fair market value on the date of exercise over the
option exercise price. Generally, with respect to employees, the Company is
required to withhold from regular wages or supplemental wage payments an amount
based on the ordinary income recognized. Subject to the requirement of
reasonableness, Section 162(m) of the Code and the satisfaction of a reporting
obligation, the Company will generally be entitled to a business expense
deduction equal to the taxable ordinary income realized by the optionee,
provided, however, that options to purchase Common Stock granted to certain
executive officers in 1997 may not be eligible for such treatment. Upon
disposition of the stock, the optionee will recognize a capital gain or loss
equal to the difference between the selling price and the sum of the amount paid
for such stock plus any amount recognized as ordinary income upon exercise of
the option. Such gain or loss will be long-term, mid-term or short-term
depending on how long the optionee holds the stock. Slightly different rules may
apply to optionees who are subject to Section 16(b) of the Exchange Act or who
acquire stock subject to certain repurchase rights.
 
    RESTRICTED STOCK PURCHASE AWARDS AND STOCK BONUSES.  Restricted stock
purchase awards and stock bonuses granted under the Incentive Plan generally
have the following federal income tax consequences:
 
                                       10
<PAGE>
    Upon acquisition of the stock, the recipient normally will recognize taxable
ordinary income equal to the excess of the stock's fair market value over the
purchase price, if any. However, to the extent the stock is subject to certain
types of vesting restrictions, the taxable event will be delayed until the
vesting restrictions lapse unless the recipient elects to be taxed on receipt of
the stock. With respect to employees, the Company is generally required to
withhold from regular wages or supplemental wage payments an amount based on the
ordinary income recognized. Generally, the Company will generally be entitled to
a business expense deduction equal to the taxable ordinary income realized by
the optionee. Upon disposition of the stock, the optionee will recognize a
capital gain or loss equal to the difference between the selling price and the
sum of the amount paid for such stock plus any amount recognized as ordinary
income upon acquisition (or vesting) of the stock. Such gain or loss will be
long-term, mid-term or short-term depending on how long the stock was held.
Slightly different rules may apply to optionees who acquire stock subject to
certain repurchase options or who are subject to Section 16(b) of the Exchange
Act.
 
    STOCK APPRECIATION RIGHTS.  No taxable income is realized upon the receipt
of a stock appreciation right, but upon exercise of the stock appreciation right
the fair market value of the shares (or cash in lieu of shares) received must be
treated as compensation taxable as ordinary income to the recipient in the year
of such exercise. Generally, with respect to employees, the Company is required
to withhold from the payment made on exercise of the stock appreciation right or
from regular wages or supplemental wage payments an amount based on the ordinary
income recognized. Subject to the requirement of reasonableness, Section 162(m)
of the Code and the satisfaction of a reporting obligation, the Company will be
entitled to a business expense deduction equal to the taxable ordinary income
recognized by the recipient, provided however, that options to purchase Common
Stock granted to certain executive officers in 1997 may not be eligible for such
treatment.
 
    POTENTIAL LIMITATION ON COMPANY DEDUCTIONS.  Code Section 162(m) denies a
deduction to any publicly held corporation for compensation paid to certain
employees in a taxable year to the extent that compensation exceeds $1 million
for a covered employee. It is possible that compensation attributable to awards
granted in the future under the Incentive Plan, when combined with all other
types of compensation received by a covered employee from the Company, may cause
this limitation to be exceeded in any particular year.
 
    Certain kinds of compensation, including qualified "performance-based
compensation," are disregarded for purposes of the deduction limitation. In
accordance with Treasury regulations issued under Section 162(m), compensation
attributable to stock options and stock appreciation rights will qualify as
performance-based compensation, provided that the option is granted by a
compensation committee comprised solely of "outside directors" and either: (i)
the option plan contains a per-employee limitation on the number of shares for
which options may be granted during a specified period, the per-employee
limitation is approved by the stockholders, and the exercise price of the option
is no less than the fair market value of the stock on the date of grant; or (ii)
the option is granted (or exercisable) only upon the achievement (as certified
in writing by the compensation committee) of an objective performance goal
established in writing by the compensation committee while the outcome is
substantially uncertain, and the option is approved by stockholders.
 
    Compensation attributable to restricted stock and stock bonuses will qualify
as performance-based compensation, provided that: (i) the award is granted by a
compensation committee comprised solely of "outside directors"; and (ii) the
purchase price of the award is no less than the fair market value of the stock
on the date of grant. Stock bonuses qualify as performance-based compensation
under the Treasury regulations only if: (i) the award is granted by a
compensation committee comprised solely of "outside directors;" (ii) the award
is granted (or exercisable) only upon the achievement of an objective
performance goal established in writing by the compensation committee while the
outcome is substantially uncertain; (iii) the compensation committee certifies
in writing prior to the granting (or exercisability) of the award that the
performance goal has been satisfied; and (iv) prior to the granting (or
exercisability) of
 
                                       11
<PAGE>
the award, stockholders have approved the material terms of the award (including
the class of employees eligible for such award, the business criteria on which
the performance goal is based, and the maximum amount (or formula used to
calculate the amount) payable upon attainment of the performance goal).
 
    The following table presents certain information with respect to options
granted under the Incentive Plan as of March 16, 1998 subject to the
stockholders' approval of the increase in the number of shares authorized for
issuance under the Incentive Plan to (i) the Company's Chief Executive Officer,
its two other most highly compensated executive officers at December 31, 1997,
including one former executive officer who departed the Company during January
1998, (the "Named Executive Officers"), (ii) all executive officers as a group,
(iii) all non-executive officer directors as a group, and (iv) all non-executive
officer employees as a group.

                                   PROPOSAL 3
               RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS
 
    The Board of Directors has selected Ernst & Young LLP as the Company's
independent auditors for the fiscal year ending December 31, 1998 and has
further directed that management submit the selection of independent auditors
for ratification by the stockholders at the Annual Meeting. Ernst & Young LLP
has audited the Company's financial statements since its inception in 1990.
Representatives of Ernst & Young LLP are expected to be present at the Annual
Meeting, will have an opportunity to make a statement if they so desire and will
be available to respond to appropriate questions.
 
    Stockholder ratification of the selection of Ernst & Young LLP as the
Company's independent auditors is not required by the Company's By-laws or
otherwise. However, the Board is submitting the selection of Ernst & Young LLP
to the stockholders for ratification as a matter of good corporate practice. If
the stockholders fail to ratify the selection, the Audit Committee and the Board
will reconsider whether or not to retain that firm. Even if the selection is
ratified, the Audit Committee and the Board in their discretion may direct the
appointment of different independent auditors at any time during the year if
they determine that such a change would be in the best interests of the Company
and its stockholders.
 
    The affirmative vote of the holders of a majority of the shares present in
person or represented by proxy and entitled to vote at the Annual Meeting will
be required to ratify the selection of Ernst & Young LLP.
 
                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 3.

                             EXECUTIVE COMPENSATION
 
DIRECTOR COMPENSATION
 
    Other than Isaac Stein and Barbara McNeil, who receive $1,000 per meeting
attended as described below, 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.
 
    Each non-employee director of the Company receives stock option grants under
the Non-Employee Directors' Stock Option Plan (the "Directors' Plan"). On
September 23, 1996, the Board of Directors amended and restated, and on October
29, 1996, the stockholders approved, the amended and restated Directors' Plan.
There are currently 250,000 shares of Common Stock authorized 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 Common Stock.
On September 8, 1996, each Non-Employee Director was granted an option to
purchase 5,000 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 additional option to purchase 15,000 shares. Each subsequently
elected Non-Employee Director has and 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
the Annual Meeting of the Company's stockholders in 1998, 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.
 
    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.
 
    As of March 16, 1998, options to purchase approximately 145,000 shares of
Common Stock had been granted under the Directors' Plan, 3,500 shares of Common
Stock has been issued upon the exercise of options, options to purchase 141,500
shares of Common Stock were outstanding and 105,000 shares remained available
for future grant.
 
    Upon certain changes in control of the Company, outstanding options will be
assumed or substituted by the surviving corporation. The Directors' Plan will
terminate in September 2006, unless earlier terminated by the Board.
 
    Under the terms of a Separation and Consulting Agreement between the Company
and Thomas L. Gutshall, the Company accepted Mr. Gutshall's resignation as
President and Chief Operating Officer effective September 2, 1996 and 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.
Pursuant to this agreement, Mr. Gutshall received $42,000 as compensation for
his consulting services in the fiscal year ended December 31, 1997. Mr. Gutshall
will receive $3,500 per month as consulting fees during the fiscal year ending
December 31, 1998.
 
    Dr. McNeil received $6,000 as compensation for her services in attending
meetings of the Board in the fiscal year ended December 31, 1997.

<PAGE>
    Mr. Stein received $5,000 as compensation for his services in attending
meetings of the Board in the fiscal year ended December 31, 1997.
 
    In 1997, as compensation for consulting services, which does not include
attendance at meetings of the Board, rendered in the fiscal year ended December
31, 1996, the Company paid Dr. Sevastopoulos $30,000 and for services rendered
in the fiscal year ended December 31, 1997, the Company paid Dr. Sevastopoulos
$25,000 and granted him 5,000 nonstatutory stock options.

(1) Each grant listed in this table was granted under the 1994 Equity Incentive
    Plan, which is described in Proposal 1. The Company has, in the past, also
    granted options to its executive officers under its 1992 Stock Option Plan.
    The terms 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,
    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. 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.
 
(2) Based on an aggregate of options to purchase 447,100 shares of the Company's
    Common Stock granted to employees and directors of, and consultants to, the
    Company during the fiscal year ended December 31, 1997, including the Named
    Executive Officers.
 
(3) 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.
 
(4) 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 market
    price of the Company's Common Stock on the date of grant 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.
 
(5) Twenty-four percent of the option vests one year from the vesting
    commencement date, with subsequent vesting at a rate of two percent per
    month until fully vested. The option expires ten years from the date of
    grant or earlier upon termination of employment.

         REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS
                          ON EXECUTIVE COMPENSATION(1)
 
    The Compensation Committee (the "Committee") of the Board of Directors
reviews and recommends to the Board of Directors for approval the Company's
executive compensation policies. During the year ended December 31, 1997, the
Committee consisted of directors Samuel D. Colella, Costa G. Sevastopoulos,
Ph.D. and J. Leighton Read, M.D., all of whom are non-employee directors. The
Committee annually evaluates the performance, and determines the compensation,
of the Company's Chief Executive Officer and the other executive officers based
upon a combination of several factors: of the achievement of corporate goals,
individual performance and comparisons with other biotechnology and
biopharmaceutical companies. The following is the report of the Committee
describing the compensation policies and rationales applicable to the Company's
executive officers with regard to the compensation payable to such executive
officers for the fiscal year ended December 31, 1997.
 
COMPENSATION PHILOSOPHY
 
    The goals of the Company's compensation policies are to attract and retain
the highest quality executives, reward them for achieving the Company's goals
and objectives, and to motivate them to contribute to the long-term success and
value of the Company for stockholders. Compensation for the Company's executive
officers consists of a base salary and potential bonus, as well as potential
incentive compensation through stock options and stock ownership. The Company
awarded cash and stock bonuses pursuant to a formal incentive bonus plan as set
forth below. The Committee considers the total current and potential long-term
compensation of each executive officer in establishing each element of
compensation.
 
BASE SALARY
 
    The base salary component is designed to compensate executive officers
competitively at levels necessary to attract and retain qualified executives in
the pharmaceutical and biotechnology industry. The base salary for each officer
is set on the basis of personal performance, the salary levels in effect for
comparable positions within the Company's principal competitors, in accordance
with published biopharmaceutical and biotechnology compensation survey
informa-tion, and other internal considerations. Based on such surveys, the
executive officers' salaries are set in the mid-range compared with other
biotechnology and biopharmaceutical companies. As a general matter, the base
salary for each executive officer is initially established through negotiation
at the time the officer is hired, taking into account such officer's
qualifications, experience, prior salary, and competitive salary information.
Year-to-year adjustments to each executive officer's base salary are based upon
personal performance for the year and changes in the general level of base
salaries of persons in comparable positions within the industry.
 
BONUSES
 
    All regular employees (including executive officers) of the Company were
eligible to receive cash bonuses in 1998 based upon achievement of individual
and corporate goals in 1997. The amounts of such bonuses for executive officers
other than the Chief Executive Officer were based upon the recommendation of the
Chief Executive Officer, subject to review and approval of the Compensation
Committee and the Board of Directors. The amounts of such bonuses for the Chief
Executive Officer were determined by the Compensation Committee subject to the
review and approval of the Board of Directors. The Company

    "filed" with the Commission, and is not to be incorporated by reference into
    any filing of the Company under the Securities Act of 1933, as amended (the
    "1933 Act") or the 1934 Act, whether made before or after the date hereof
    and irrespective of any general incorporation language contained in such
    filing.
 
                                       22

makes determinations with respect to bonuses based upon a subjective assessment
of a variety of factors, both personal and corporate. These factors include, in
order of importance, the progress of the Company in fulfilling its yearly
performance objectives and the individual performance of each executive officer
and a comparison with other biotechnology and biopharmaceutical companies. The
Company's key goals in 1997 included advancing the Company's lead products
through development and clinical testing within the budget established by the
Board of Directors, recruiting high quality management team, planning and
entering into appropriate collaborative arrangements with pharmaceutical and
biotechnology companies relating to the development of additional products and
securing additional capital to enable the Company to fund operations through
1998. In December, 1997, the Company reviewed the corporate goals and determined
that 90% of the 1997 goals had been achieved. In addition, in 1997, the Board of
Directors awarded a one-time stock bonus to certain key executives and employees
who played a significant role in the Company's collaboration with Biogen.
 
LONG-TERM INCENTIVES
 
    The Committee provides the Company's executive officers with long-term
incentive compensation through grants of stock options under the Company's 1994
Equity Incentive Plan. The Committee believes that stock options provide the
Company's executive officers with the opportunity to purchase and maintain an
equity interest in the Company and to share in the appreciation of the value of
the Company's Common Stock. The Committee believes that stock options directly
motivate executives to maximize long-term stockholder value. The options also
utilize vesting periods (generally four years) that encourage key executives to
continue in the employ of the Company. All options granted to executive officers
to date have been granted at the fair market value of the Company's Common Stock
on the date of grant. The Committee considers the grant of each option
subjectively, considering factors such as the progress of the Company in
fulfilling its yearly performance objectives, individual performance of the
executive officer and the past and anticipated future contribution of the
executive officer to the attainment of the Company's long-term strategic
performance goals. Long-term incentives granted in prior years, including the
number of unvested options, are also taken into consideration. Consistent with
these policies, the Committee granted options to purchase 52,500 shares of
Common Stock to three Executive Officers during 1997.
 
CHIEF EXECUTIVE OFFICER COMPENSATION
 
    The compensation of the Chief Executive Officer is reviewed annually on the
same basis as discussed above for all executive officers. In 1997, Louis G.
Lange received a base salary of $257,500. Dr. Lange's salary was determined on
the basis of negotiations between the Board of Directors and Dr. Lange with due
regard for his qualifications, experience, prior salary, and competitive salary
information. Dr. Lange's base salary for 1997 was established in part by
comparing the base salaries of chief executive officers at other biotechnology
and pharmaceutical companies of similar size. In awarding stock options, the
Committee considered Dr. Lange's performance, the overall contribution to the
Company and the Company's achievement of its performance objectives, the number
of unvested options and total number of options to be granted. In 1997, Dr Lange
received an option to purchase 30,000 shares of Common Stock. In addition, Dr.
Lange received a 2,500 stock bonus valued at $25,000 in 1997 which was paid in
consideration for his performance during 1996. As with other executive officers,
total compensation was based, in part, on the Company's accomplishments and Dr.
Lange's contribution thereto, including initiation of the Phase III clinical
program for ranolazine, closing the partnership agreement with Biogen, Inc. for
CVT-124, completing the Phase II clinical trial for CVT-124, raising $12.9
million through a private placement of equity securities with Biotech Target
S.A., and identifying CVT-510 as an IND candidate for 1998.

SECTION 162(M)
 
    The Board has considered the potential effect of Section 162(m) of the
Internal Revenue Code of 1996, as amended, on compensation paid to the Company's
executive officers. Section 162(m) disallows a tax deduction for any
publicly-held corporation for individual compensation exceeding $1.0 million in
any taxable year for each of the executive officers named in the proxy
statement. Compensation above $1 million may be deducted if it is
"performance-based compensation." The Committee has determined that, where
practical, stock options granted under the Company's 1994 Equity Incentive Plan
with an exercise price of at least equal to the fair market value of the
Company's Common Stock on the date of grant shall be treated as
"performance-based compensation;" provided, however, that options to purchase
Common Stock granted to certain executive officers in 1997 may not be eligible
for such treatment.

                     PERFORMANCE MEASUREMENT COMPARISON(2)
 
    The following graph shows the total stockholder return of an investment of
$100 in cash since the Company's initial public offering of Common Stock on
November 19, 1996 through December 31, 1997 for (i) the Company's Common Stock,
(ii) the Nasdaq Stock Market (U.S.) Index ("Nasdaq"), (iii) the Nasdaq
Pharmaceutical Index ("Nasdaq Pharmaceutical") and (iv) the Hambrecht & Quist
Biotechnology Index ("H&Q Biotechnology"). The Company will be using the H&Q
Biotechnology rather than the Nasdaq Pharmaceutical going forward because the
Company believes the H&Q Biotechnology is a more representative comparator of
the Company's industry and peer group. All values assume reinvestment of the
full amount of all dividends, although dividends have not been declared on the
Company's Common Stock.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
LOANS
 
    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%,
pursuant to a promissory note secured by a stock pledge of 2,500 shares of
Common Stock held by Dr. Lange (the "1993 Note"). In June 1995, in connection
with the exercise of an option to purchase Common Stock, the Company provided a
loan in the principal amount of $37,500, at an annual interest rate of 7.31%,
pursuant to a promissory note secured by a pledge of 15,000 shares of Common
Stock held by Dr. Lange (the "1995 Note"). In August 1996, the Company provided
a loan to Dr. Lange in the principal amount of $25,000, at an annual interest
rate of 6.84%, pursuant to a promissory note secured by a pledge of 2,500 shares
of Common Stock held by Dr. Lange (the "1996 Note").
 
    In September 1996, the Company amended all four notes. Under the terms of
each amended note, the loans bear 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. At the
same time, the Company forgave all interest due on the four loans as of December
31, 1995 ($92,880). In addition, the Company will pay Dr. Lange an amount
necessary to compensate him for any taxes that he may incur due to the interest
forgiveness as well as the following amounts for mortgage assistance: $50,000 in
1997, $40,000 in 1998, $30,000 in 1999, $20,000 in 2000 and $10,000 in 2001. The
forgiveness of the accrued interest on the notes to Dr. Lange was accounted for
as compensation expense in the period in which the interest was deemed to have
been forgiven.
 
    The largest aggregate principal amount outstanding on the four notes in 1997
was $437,500. Under the terms of an Amended and Restated Stock Pledge Agreement,
the 1993 Note, 1995 Note and 1996 Note are secured by a stock pledge of 13,750
shares of Common Stock held by Dr. Lange. As of March 16, 1998, an aggregate
principal amount of $437,500 remained outstanding on the four notes.
 
    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. In connection with a Separation and Consulting Agreement effective as
of September 2, 1996, the Company amended the note to provide that the loan bore
interest at the rate of 6.53% compounded semi-annually and the outstanding
principal amount was due on the earliest of December 31, 2001, the voluntary
termination of association or a change in control. The largest aggregate
principal amount outstanding on the note in 1996 and the aggregate principal
amount outstanding on the note in 1997 was $62,500. In July 1997, Mr. Gutshall
repaid the outstanding principal amount and accrued interest on the note.
 
    In November 1992, the Company provided a loan to George F. Schreiner, M.D.,
Ph.D., who served as Vice President, Medical Science and Preclinical Research
from January 1993 through January 1997, in the principal amount of $75,000, at
an annual interest rate of 6.5%, pursuant to a promissory note secured by a deed
of trust on Dr. Schreiner's residence. In September 1996, the Company amended
the note. Under the terms of the amended note, the loan bore interest at the
rate of 6.53% compounded semi-annually and the outstanding principal amount was
due on the earliest of December 31, 2001, the termination of employment or a
change in control. The largest aggregate principal amount outstanding in 1997
was $75,000. In January 1997, Dr. Schreiner resigned from the Company. In April
1997, Dr. Schreiner repaid the outstanding principal amount and accrued interest
on the note.

    granted; whether a Stock Award will be an Incentive Stock Option, a

    (a) Subject to the provisions of Section 12 relating to adjustments upon
changes in stock, the stock that may be issued pursuant to Stock Awards shall
not exceed in the aggregate 1,8000,000 shares of the Company's common stock. If
any Stock Award shall for any reason expire or otherwise terminate without
having been exercised in full (or vested in the case of Restricted Stock), the
stock not acquired under such Stock Award shall again become available for the
Plan. Shares subject to Stock Appreciation Rights exercised in accordance with
Section 8 of the Plan shall not be available for subsequent issuance under the
Plan. (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.
 
5.  ELIGIBILITY.
 
    (a) Incentive Stock Options and Stock Appreciation Rights appurtenant
thereto may be granted only to Employees. Stock Awards other than Incentive
Stock Options and Stock Appreciation Rights appurtenant thereto may be granted
only to Employees, Directors or Consultants.
 
    (b) No person shall be eligible for the grant of an Incentive Stock Option

Section 424(d) of the Code) stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or of any of
its Affiliates unless the exercise price of such Incentive Stock Option is at

the date of grant and the Incentive Stock Option is not exercisable after the
expiration of five (5) years from the date of grant.
 
    (c) Subject to the provisions of Section 11 relating to adjustments upon
changes in the Common Stock, no person shall be eligible to be granted Options
and Stock Appreciation Rights covering more than one hundred thousand (100,000)
shares of the Company's common stock in any calendar year.
 
6.  OPTION PROVISIONS.
 
    Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:
 
        (a) TERM.  No Option shall be exercisable after the expiration of ten
    (10) years from the date it was granted.
 
        (b) PRICE.  The exercise price of each Incentive Stock Option shall be
    not less than one hundred percent (100%) of the Fair Market 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 eighty-five
    percent (85%) of the Fair Market Value of the stock subject to the Option on
    the date the Option is granted. Notwithstanding the foregoing, an Option may
    be granted with an exercise price lower than that set forth in the preceding
    sentence if such Option is granted pursuant to an assumption or substitution
    for another option in a manner satisfying the provisions of Section 424(a)
    of the Code.
 
        (c) CONSIDERATION.  The purchase price of stock acquired pursuant to an
    Option shall be paid, to the extent permitted by applicable statutes and
    regulations, either (i) in cash at the time the option is exercised, or (ii)
    at the discretion of the Board or the Committee, either at the time of the
    grant or exercise of the Option, (A) by delivery to the Company of other
    common stock of the Company, (B) according to a deferred payment or other
    arrangement (which may include, without limiting the generality of the
    foregoing, the use of other common stock of the Company) with the person to
    whom the Option is granted or to whom the Option is transferred pursuant to
    subsection 6(d), or (C) in any other form of legal consideration that may be
    acceptable to the Board.
 
                                       31
<PAGE>
    In the case of any deferred payment arrangement, interest shall be payable
at least annually and shall be charged at the minimum rate of interest necessary
to avoid the treatment as interest, under any applicable provisions of the Code,
of any amounts other than amounts stated to be interest under the deferred
payment arrangement.
 
        (d) TRANSFERABILITY.  An Incentive Stock Option shall not be
    transferable except by will or by the laws of descent and distribution, and
    shall be exercisable during the lifetime of the person to whom the Incentive
    Stock Option is granted only by such person. A Nonstatutory Stock Option may
    be transferred to the extent expressly provided in the Option Agreement. The
    person to whom the Option is granted may, by delivering written notice to
    the Company, in a form satisfactory to the Company, designate a third party
    who, in the event of the death of the Optionee, shall thereafter be entitled
    to exercise the Option.
 
        (e) VESTING.  The total number of shares of stock subject to an Option
    may, but need not, be allotted in periodic installments (which may, but need
    not, be equal). The Option Agreement may provide that from time to time
    during each of such installment periods, the Option may become exercisable
    ("vest") with respect to some or all of the shares allotted to that period,
    and may be exercised with respect to some or all of the shares allotted to
    such period and/or any prior period as to which the Option became vested but
    was not fully exercised. The Option may be subject to such other terms and
    conditions on the time or times when it may be exercised (which may be based
    on performance criteria) as the Board may deem appropriate. The provisions
    of this subsection 6(e) are subject to any Option provisions governing the
    minimum number of shares as to which an Option may be exercised.
 
        (f) SECURITIES LAW COMPLIANCE.  The Company may require any Optionee, or
    any person to whom an Option is transferred under subsection 6(d), as a
    condition of exercising any such Option, (1) to give written assurances
    satisfactory to the Company as to the Optionee's knowledge and experience in
    financial and business matters and/or to employ a purchaser representative
    reasonably satisfactory to the Company who is knowledgeable and experienced
    in financial and business matters, and that he or she is capable of
    evaluating, alone or together with the purchaser representative, the merits
    and risks of exercising the Option; and (2) to give written assurances
    satisfactory to the Company stating that such person is acquiring the stock
    subject to the Option for such person's own account and not with any present
    intention of selling or otherwise distributing the stock. These
    requirements, and any assurances given pursuant to such requirements, shall
    be inoperative if (i) the issuance of the shares upon the exercise of the
    Option has been registered under a then currently effective registration
    statement under the Securities Act of 1933, as amended (the "Securities
    Act"), or (ii) as to any particular requirement, a determination is made by
    counsel for the Company that such requirement need not be met in the
    circumstances under the then applicable securities laws.
 
        (g) TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
    CONSULTANT.  In the event an Optionee's Continuous Status as an Employee,
    Director or Consultant terminates (other than upon the Optionee's death or
    disability), the Optionee may exercise his or her Option, but only within
    such period of time as is determined by the Board and only to the extent
    that the Optionee was entitled to exercise it at the date of termination
    (but in no event later than the expiration of the term of such Option as set
    forth in the Option Agreement). If, at the date of termination, the Optionee
    is not entitled to exercise his or her entire Option, the shares covered by
    the unexercisable portion of the Option shall revert to the Plan. If, after
    termination, the Optionee does not exercise his or her Option within the
    time specified in the Option Agreement, the Option shall terminate, and the
    shares covered by such Option shall revert to the Plan.
 
        (h) DISABILITY OF OPTIONEE.  In the event an Optionee's Continuous
    Status as an Employee, Director or Consultant terminates as a result of the
    Optionee's disability, the Optionee may exercise his or her Option, but only
    within twelve (12) months from the date of such termination (or such
 
                                       32
<PAGE>
    shorter or longer period specified in the Option Agreement), and only to the
    extent that the Optionee was entitled to exercise it at the date of such
    termination (but in no event later than the expiration of the term of such
    Option as set forth in the Option Agreement). If, at the date of
    termination, the Optionee is not entitled to exercise his or her entire
    Option, the shares covered by the unexercisable portion of the Option shall
    revert to the Plan. If, after termination, the Optionee does not exercise
    his or her Option within the time specified herein, the Option shall
    terminate, and the shares covered by such Option shall revert to the Plan.
 
        (i) DEATH OF OPTIONEE.  In the event of the death of an Optionee, the
    Option may be exercised, at any time within eighteen (18) months following
    the date of death (or such shorter or longer period specified in the Option
    Agreement) (but in no event later than the expiration of the term of such
    Option as set forth in the Option Agreement), by the Optionee's estate or by
    a person who acquired the right to exercise the Option by bequest or
    inheritance, but only to the extent the Optionee was entitled to exercise
    the Option at the date of death. If, at the time of death, the Optionee was
    not entitled to exercise his or her entire Option, the shares covered by the
    unexercisable portion of the Option shall revert to the Plan. If, after
    death, the Optionee's estate or a person who acquired the right to exercise
    the Option by bequest or inheritance does not exercise the Option within the
    time specified herein, the Option shall terminate, and the shares covered by
    such Option shall revert to the Plan.
 
        (j) EARLY EXERCISE.  The Option may, but need not, include a provision
    whereby the Optionee may elect at any time while an Employee, Director or
    Consultant to exercise the Option as to any part or all of the shares
    subject to the Option prior to the full vesting of the Option. 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.
    Should the right of repurchase be assigned by the Company, the assignee
    shall pay the Company cash equal to the difference between the original
    purchase price and the stock's Fair Market Value if the original price is
    less than the stock's Fair Market Value.
 
        (k) WITHHOLDING.  To the extent provided by the terms of an Option
    Agreement, the Optionee may satisfy any federal, state or local tax
    withholding obligation relating to the exercise of such Option by any of the
    following means or by a combination of such means: (1) tendering a cash
    payment; (2) authorizing the Company to withhold shares from the shares of
    the common stock otherwise issuable to the participant as a result of the
    exercise of the Option; or (3) delivering to the Company owned and
    unencumbered shares of the common stock of the Company.
 
        (l) RE-LOAD OPTIONS.  Without in any way limiting the authority of the
    Board or Committee to make or not to make grants of Options hereunder, the
    Board or Committee shall have the authority (but not an obligation) to
    include as part of any Option Agreement a provision entitling the Optionee
    to a further Option (a "Re-Load Option") in the event the Optionee exercises
    the Option evidenced by the Option agreement, in whole or in part, by
    surrendering other shares of Common Stock in accordance with this Plan and
    the terms and conditions of the Option Agreement. Any such Re-Load Option
    (i) shall be for a number of shares equal to the number of shares
    surrendered as part or all of the exercise price of such Option; (ii) shall
    have an expiration date which is the same as the expiration date of the
    Option the exercise of which gave rise to such Re-Load Option; and (iii)
    shall have an exercise price which is equal to one hundred percent (100%) of
    the Fair Market Value of the Common Stock subject to the Re-Load Option on
    the date of exercise of the original Option or, in the case of a Re-Load
    Option which is an Incentive Stock Option and which is granted to a 10%
    stockholder (as described in subparagraph 5(c)), shall have an exercise
    price which is equal to one hundred ten percent (110%) of the Fair Market
    Value of the stock subject to the Re-Load Option on the date of exercise of
    the original Option and shall have a term not to exceed five (5) years.
 
    Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
Stock Option, as the Board or Committee may designate at the time of the grant
of the original Option, provided, however, that
 
                                       33
<PAGE>
the designation of any Re-Load Option as an Incentive Stock Option shall be
subject to the one hundred thousand dollars ($100,000) annual limitation on
exercisability of Incentive Stock Options described in subparagraph 11(d) of the
Plan and in Section 422(d) of the Code. There shall be no Re-Load Options on a
Re-Load Option. Any such Re-Load Option shall be subject to the availability of
sufficient shares under subparagraph 4(a) and shall be subject to such other
terms and conditions as the Board or Committee may determine.
 
7.  TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.
 
    Each stock bonus or restricted stock purchase agreement shall be in such
form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate. The terms and conditions of stock bonus or restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate agreements need not be identical, but each stock bonus or
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions as appropriate:
 
        (a) PURCHASE PRICE.  The purchase price under each restricted stock
    purchase agreement shall be such amount as the Board or Committee shall
    determine and designate in such agreement. Notwithstanding the foregoing,
    the Board or the Committee may determine that eligible participants in the
    Plan may be awarded stock pursuant to a stock bonus agreement in
    consideration for past services actually rendered to the Company or for its
    benefit.
 
        (b) TRANSFERABILITY.  No rights under a stock bonus or restricted stock
    purchase agreement shall be assignable by any participant under the Plan,
    either voluntarily or by operation of law, except where such assignment is
    required by law or expressly authorized by the terms of the applicable stock
    bonus or restricted stock purchase agreement.
 
        (c) CONSIDERATION.  The purchase price of stock acquired pursuant to a
    stock purchase agreement shall be paid either: (i) in cash at the time of
    purchase; (ii) at the discretion of the Board or the Committee, according to
    a deferred payment or other arrangement with the person to whom the stock is
    sold; or (iii) in any other form of legal consideration that may be
    acceptable to the Board or the Committee in their discretion.
    Notwithstanding the foregoing, the Board or the Committee to which
    administration of the Plan has been delegated may award stock pursuant to a
    stock bonus agreement in consideration for past services actually rendered
    to the Company or for its benefit.
 
        (d) VESTING.  Shares of stock sold or awarded under the Plan may, but
    need not, be subject to a repurchase option in favor of the Company in
    accordance with a vesting schedule to be determined by the Board or the
    Committee.
 
        (e) TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
    CONSULTANT.  In the event a Participant's Continuous Status as an Employee,
    Director or Consultant terminates, the Company may repurchase or otherwise
    reacquire any or all of the shares of stock held by that person which have
    not vested as of the date of termination under the terms of the stock bonus
    or restricted stock purchase agreement between the Company and such person.
 
8.  STOCK APPRECIATION RIGHTS.
 
    (a) The Board or Committee shall have full power and authority, exercisable
in its sole discretion, to grant Stock Appreciation Rights to Employees or
Directors of or Consultants to, the Company or its Affiliates under the Plan.
Each such right shall entitle the holder to a distribution based on the
appreciation in the Fair Market Value per share of a designated amount of stock.
 
                                       34
<PAGE>
    (b) Three types of Stock Appreciation Rights shall be authorized for
issuance under the Plan:
 
        (i) TANDEM STOCK APPRECIATION RIGHTS.  Tandem Rights will be granted
    appurtenant to an Option and will require the holder to elect between the
    exercise of the underlying Option for shares of stock and the surrender, in
    whole or in part, of such Option for an appreciation distribution equal to
    the excess of (A) the Fair Market Value (on the date of Option surrender) of
    vested shares of stock purchasable under the surrendered Option over (B) the
    aggregate exercise price payable for such shares.
 
        (ii) CONCURRENT STOCK APPRECIATION RIGHTS.  Concurrent Rights will be
    granted appurtenant to an Option and may apply to all or any portion of the
    shares of stock subject to the underlying Option and will be exercised
    automatically at the same time the Option is exercised for those shares. The
    appreciation distribution to which the holder of such concurrent right shall
    be entitled upon exercise of the underlying Option shall be in an amount
    equal to the excess of (A) the aggregate Fair Market Value (at date of
    exercise) of the vested shares purchased under the underlying Option with
    such concurrent rights over (B) the aggregate exercise price paid for those
    shares.
 
       (iii) INDEPENDENT STOCK APPRECIATION RIGHTS.  Independent Rights may be
    granted independently of any Option and will entitle the holder upon
    exercise to an appreciation distribution equal in amount to the excess of
    (A) the aggregate Fair Market Value (at the date of exercise) of a number of
    shares of stock equal to the number of vested share equivalents exercised at
    such time (as described in subsection 7(c)(iii)(B)) over (B) the aggregate
    Fair Market Value of such number of shares of stock at the date of grant.
 
    (c) The terms and conditions applicable to each Tandem Right, Concurrent
Right and Independent Right shall be as follows:
 
        (i) TANDEM RIGHTS.
 
           (A) Tandem Rights may be tied to either Incentive Stock Options or
       Nonstatutory Stock Options. Each such right shall, except as specifically
       set forth below, be subject to the same terms and conditions applicable
       to the particular Option to which it pertains. If Tandem Rights are
       granted appurtenant to an Incentive Stock Option, they shall satisfy any
       applicable Treasury Regulations so as not to disqualify such Option as an
       Incentive Stock Option under the Code.
 
           (B) The appreciation distribution payable on the exercised Tandem
       Right shall be in cash in an amount equal to the excess of (I) the Fair
       Market Value (on the date of the Option surrender) of the number of
       shares of stock covered by that portion of the surrendered Option in
       which the optionee is vested over (II) the aggregate exercise price
       payable for such vested shares.
 
        (ii) CONCURRENT RIGHTS.
 
           (A) Concurrent Rights may be tied to any or all of the shares of
       stock subject to any Incentive Stock Option or Nonstatutory Stock Option
       grant made under the Plan. A Concurrent Right shall, except as
       specifically set forth below, be subject to the same terms and conditions
       applicable to the particular Option grant to which it pertains.
 
           (B) A Concurrent Right shall be automatically exercised at the same
       time the underlying Option is exercised with respect to the particular
       shares of stock to which the Concurrent Right pertains.
 
           (C) The appreciation distribution payable on an exercised Concurrent
       Right shall be in cash in an amount equal to such portion as shall be
       determined by the Board or the Committee at the time of the grant of the
       excess of (I) the aggregate Fair Market Value (on the Exercise Date) of
 
                                       35
<PAGE>
       the vested shares of stock purchased under the underlying Option which
       have Concurrent Rights appurtenant to them over (II) the aggregate
       exercise price paid for such shares.
 
       (iii) INDEPENDENT RIGHTS.
 
           (A) Independent Rights shall, except as specifically set forth below,
       be subject to the same terms and conditions applicable to Nonstatutory
       Stock Options as set forth in Section 6. They shall be denominated in
       share equivalents.
 
           (B) The appreciation distribution payable on the exercised
       Independent Right shall be in an amount equal to the excess of (I) the
       aggregate Fair Market Value (on the date of the exercise of the
       Independent Right) of a number of shares of Company stock equal to the
       number of share equivalents in which the holder is vested under such
       Independent right, and with respect to which the holder is exercising the
       Independent Right on such date, over (II) the aggregate Fair Market Value
       (on the date of the grant of the Independent Right) of such number of
       shares of Company stock.
 
           (C) The appreciation distribution payable on the exercised
       Independent Right may be paid, in the discretion of the Board or the
       Committee, in cash, in shares of stock or in a combination of cash and
       stock. Any shares of stock so distributed shall be valued at Fair Market
       Value on the date the Independent Right is exercised.
 
        (iv) TERMS APPLICABLE TO TANDEM RIGHTS, CONCURRENT RIGHTS AND
    INDEPENDENT RIGHTS.
 
           (A) To exercise any outstanding Tandem, Concurrent or Independent
       Right, the holder must provide written notice of exercise to the Company
       in compliance with the provisions of the instrument evidencing such
       right.
 
           (B) If a Tandem, Concurrent, or Independent Right is granted to an
       individual who is at the time subject to Section 16(b) of the Exchange
       Act (a "Section 16(b) Insider"), then the instrument of grant shall
       incorporate all the terms and conditions at the time necessary to assure
       that the subsequent exercise of such right shall qualify for the
       safe-harbor exemption from short-swing profit liability provided by Rule
       16b-3 promulgated under the Exchange Act (or any successor rule or
       regulation).
 
           (C) No limitation shall exist on the aggregate amount of cash
       payments the Company may make under the Plan in connection with the
       exercise of Tandem, Concurrent or Independent Rights.
 
9.  COVENANTS OF THE COMPANY.
 
    (a) During the terms of the Stock Awards, the Company shall keep available
at all times the number of shares of stock required to satisfy such Stock Awards
up to the number of shares of stock authorized under the Plan.
 
    (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock under the Stock Awards; provided, however, that
this undertaking shall not require the Company to register under the Securities
Act either the Plan, any Stock Award or any stock issued or issuable pursuant to
any such Stock Award. If, after reasonable efforts, the Company is unable to
obtain from any such regulatory commission or agency the authority which counsel
for the Company deems necessary for the lawful issuance and sale of stock under
the Plan, the Company shall be relieved from any liability for failure to issue
and sell stock under such Stock Awards unless and until such authority is
obtained.
 
                                       36
<PAGE>
10. USE OF PROCEEDS FROM STOCK.
 
    Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.
 
11. MISCELLANEOUS.
 
    (a) The Board shall have the power to accelerate the time at which a Stock
Award may first be exercised or the time during which a Stock Award or any part
thereof will vest, notwithstanding the provisions in the Stock Award stating the
time at which it may first be exercised or the time during which it will vest.
 
    (b) Neither an Optionee nor any person to whom an Option is transferred
under subsection 6(d) shall be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares subject to such Option unless and
until such person has satisfied all requirements for exercise of the Option
pursuant to its terms.
 
    (c) Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any Employee, Director, Consultant, Optionee,
or other holder of Stock Awards any right to continue in the employ of the
Company or any Affiliate (or to continue acting as a Director or Consultant) or
shall affect the right of the Company or any Affiliate to terminate the
employment or relationship as a Director or Consultant of any Employee,
Director, Consultant or Optionee with or without cause.
 
    (d) To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options granted
after 1986 are exercisable for the first time by any Optionee during any
calendar year under all plans of the Company and its Affiliates exceeds one
hundred thousand dollars ($100,000), the Options or portions thereof which
exceed such limit (according to the order in which they were granted) shall be
treated as Nonstatutory Stock Options.
 
12. ADJUSTMENTS UPON CHANGES IN STOCK.
 
    (a) If any change is made in the stock subject to the Plan, or subject to
any Stock Award, without the receipt of consideration by the Company (through
merger, consolidation, reorganization, recapitalization, stock dividend,
dividend in property other than cash, stock split, liquidating dividend,
combination of shares, exchange of shares, change in corporate structure or
otherwise), the Plan and outstanding Stock Awards will be appropriately adjusted
in the class(es) and maximum number of shares subject to the Plan and the
class(es) and number of shares and price per share of stock subject to
outstanding Stock Awards. The conversion of any convertible securities of the
Company shall not be treated as a transaction "without the receipt of
consideration by the Company."
 
    (b) In the event of a Change in Control not approved by the Board, each
outstanding Option under the Plan shall become fully vested, and the Company's
right of repurchase shall lapse with respect to shares received upon exercise of
an Option prior to full vesting, notwithstanding the terms of the Option or any
early exercise stock purchase agreement, immediately prior to the consummation
of such Change in Control.
 
    In addition, following the consummation of a Change in Control, to the
extent permitted by applicable law: (i) any surviving corporation or a parent of
such surviving corporation shall assume any Stock Awards outstanding under the
Plan or shall substitute similar Stock Awards for those outstanding under the
Plan or (ii) such Stock Awards shall continue in full force and effect, unless
(iii) the surviving corporation or parent of the surviving corporation refuses
to assume or continue any Stock Awards outstanding under the Plan, or to
substitute similar options for those outstanding under the Plan. If the
surviving corporation or parent of the surviving corporation refuses to assume
or continue any Stock Awards outstanding under the Plan, or to substitute
similar options for those outstanding under the Plan, then the time during which
any outstanding Stock Awards may be exercised shall be accelerated, the Stock
Awardees shall be given
 
                                       37
<PAGE>
reasonable opportunity to exercise such Stock Awards prior to the consummation
of the Change in Control, and such Stock Awards shall be terminated if not
exercised prior to the consummation of the Change in Control.
 
    For purposes of this Plan, "Change in Control" means: (i) a sale of
substantially all of the assets of the Company; (ii) a merger or consolidation
in which the Company is not the surviving corporation (other than a merger or
consolidation in which shareholders immediately before the merger or
consolidation have, immediately after the merger or consolidation, equal or
greater stock voting power); (iii) a reverse merger in which the Company is the
surviving corporation but the shares of the Company's common stock outstanding
immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of securities, cash or otherwise (other than
a reverse merger in which stockholders immediately before the merger have,
immediately after the merger, greater stock voting power); or (iv) any
transaction or series of related transactions in which in excess of 50% of the
Company's voting power is transferred.
 
13. AMENDMENT OF THE PLAN AND STOCK AWARDS.
 
    (a) The Board at any time, and from time to time, may amend the Plan and,
subject to (c) below, outstanding Stock Awards. However, except as provided in
Section 12 relating to adjustments upon changes in stock, no amendment shall be
effective unless approved by the stockholders of the Company to the extent
stockholder approval is necessary for the Plan to satisfy the requirements of
Section 422 of the Code, Rule 16b-3 or any Nasdaq or securities exchange listing
requirements.
 
    (b) It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide Optionees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to Incentive Stock Options
and/or to bring the Plan and/or Incentive Stock Options granted under it into
compliance therewith.
 
    (c) Rights and obligations under any Stock Award granted before amendment of
the Plan shall not be altered or impaired by any amendment of the Plan unless
(i) the Company requests the consent of the person to whom the Stock Award was
granted and (ii) such person consents in writing.
 
14. TERMINATION OR SUSPENSION OF THE PLAN.
 
    (a) The Board may suspend or terminate the Plan at any time. Unless sooner
terminated, the Plan shall terminate on September 23, 2006. No Stock Awards may
be granted under the Plan while the Plan is suspended or after it is terminated.
 
    (b) Rights and obligations under any Stock Award granted while the Plan is
in effect shall not be altered or impaired by suspension or termination of the
Plan, except with the consent of the person to whom the Stock Award was granted.
 
15. EFFECTIVE DATE OF PLAN.
 
    The Plan shall become effective as determined by the Board, but no Stock
Awards granted under the Plan shall be exercisable unless and until the Plan has
been approved by the stockholders of the Company.
