                            ------------------------
 
                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
    The enclosed proxy is solicited on behalf of the Board of Directors of
Affymetrix, Inc. for use at the annual meeting of shareholders to be held on
Friday, June 6, 1997 at 10:00 a.m., local time, or at any adjournment of the
meeting, for the purposes set forth in this Proxy Statement and in the
accompanying Notice of Annual Meeting of Shareholders. The annual meeting will
be held at 3380 Central Expressway, Santa Clara, California 95051. The Company's
telephone number is (408) 731-5000.
 
    These proxy solicitation materials were mailed on or about April 28, 1997,
together with the Company's 1996 Annual Report to Shareholders, to all
shareholders entitled to vote at the meeting.
 
RECORD DATE
 
    Shareholders of record at the close of business on April 21, 1997 (the
"Record Date") are entitled to notice of and to vote at the meeting. At the
Record Date, approximately 22,598,000 shares of the Company's Common Stock were
issued and outstanding.
 
REVOCABILITY OF PROXIES
 
    Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use by delivering to the Company a written
notice of revocation or a duly executed proxy bearing a later date or time, or
by attending the meeting and voting in person.
 
VOTING AND SOLICITATION
 
    The Company has one type of security entitled to vote at the meeting, its
Common Stock. Each share entitles you to one vote on each matter to come before
the meeting. The Company's Articles of Incorporation do not provide for
cumulative voting.
 
    The cost of soliciting proxies will be borne by the Company. Proxies may
also be solicited by certain of the Company's directors, officers and employees,
without additional compensation, personally or by telephone, facsimile or
letter.
 
QUORUM; ABSTENTIONS, AND BROKER NON-VOTES
 
    The required quorum for the transaction of business at the annual meeting is
a majority of the shares of Common Stock outstanding on the Record Date. Broker
non-votes and shares held by persons abstaining will be counted in determining
whether a quorum is present at the annual meeting. However, abstentions are
counted as votes against a proposal for purposes of determining whether or not a
proposal has been approved, whereas broker non-votes are not counted for
purposes of determining whether a proposal has been approved.
 
DEADLINE FOR RECEIPT OF SHAREHOLDER PROPOSALS
 
    Proposals of shareholders of the Company which are intended to be presented
by such shareholders at next year's annual meeting must be received by the
Company no later than December 29, 1997 in order that they may be included in
the proxy statement and form of proxy relating to the 1998 annual meeting.

            THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS
                    VOTE "FOR" THE ELECTION OF THE NOMINEES.
 
BOARD MEETINGS AND COMMITTEES
 
    The Board of Directors of the Company held a total of eight meetings during
the fiscal year ended December 31, 1996. Each director other than Mr. Loucks
attended at least seventy-five percent of the meetings of the Board of Directors
and each committee on which the director served during 1996.
 
    The Board of Directors has an Audit Committee, a Compensation Committee and
a Nominating Committee.
 
    The Audit Committee of the Board of Directors, which consisted of directors
Hurt, Singer and Young held three meetings during 1996. The Audit Committee
oversees the actions taken by the Company's independent auditors and reviews the
Company's internal financial and accounting controls and policies.
 
    The Compensation Committee of the Board of Directors, which consisted of
directors Berg, Young and Zaffaroni, held four meetings during 1996. The
Compensation Committee is responsible for determining salaries, incentives and

    The Nominating Committee, which consisted of directors Diekman, Loucks and
Young, met once during 1996. The Nominating Committee is responsible for
proposing candidates to fill any vacancies on the Board.
 
COMPENSATION OF DIRECTORS
 
    Non-employee directors receive a fee of $2,500 per Board meeting attended as
well as reimbursement of expenses incurred in attending Board meetings. In
addition, the Company's 1996 Nonemployee Directors Stock Option Plan (the
"Directors Plan") provides for the automatic grant of 33,333 shares of Common
Stock if a person who is neither an officer nor an employee of the Company and
who has not previously been a member of the Board is elected or appointed
director. Each such option vests at the rate of one-fifth of the number of
shares covered by the option on each anniversary of the grant date so long as
the director is serving on the Board with full vesting over five years. In
addition, on the date of each annual meeting of the shareholders of the Company
held after January 1, 2001 for nonemployee directors elected prior to March 1996
who continue on the Board, and 54 months after the initial option grant to
nonemployee directors elected after March 1996 who continue on the Board, each
such nonemployee director will receive an option to purchase 6,667 shares of the
Company's Common Stock, with full vesting one year after grant. The exercise
price of all options granted pursuant to the Directors Plan is the fair market
value of the Company's Common Stock at the time of grant.
 
                               AMENDMENTS TO THE
                      AMENDED AND RESTATED 1993 STOCK PLAN
 
BACKGROUND
 
    The Company adopted the 1993 Amended and Restated Stock Plan (the "1993
Stock Plan") in July 1993. The 1993 Stock Plan provides for the granting of
options to officers, directors, employees and consultants. The 1993 Stock Plan
is currently administered by the Compensation Committee of the Board.
 
    ADDITION OF SHARES.  A total of 3,700,000 shares of Common Stock is
currently reserved for issuance under the 1993 Stock Plan. The Board has
approved, subject to shareholder approval, the amendment to the 1993 Stock Plan
to reserve an additional 1,500,000 shares for issuance upon exercise of options
granted under the 1993 Stock Plan, bringing the total number of shares under the
Plan to 5,200,000. If approved by stockholders, approximately 1,628,400 shares
would be available for grant under the 1993 Stock Plan.
 
                                       4
<PAGE>
Management expects this share increase to be sufficient for all grants made
under the 1993 Stock Plan for at least two years.
 
    LIMIT ON NUMBER OF SHARES.  Section 162(m) of the Internal Revenue Code of
1986, as amended (the "Code"), enacted in August 1993, limits the deductibility
by public companies of compensation in excess of $1 million per year (subject to
some exemptions) paid to certain executive officers (generally, the Chief
Executive Officer and the other four most highly compensated executive
officers). As the limit applies in the year in which the compensation is paid,
it could apply to income derived from the exercise of certain stock options,
measured by the spread between the exercise price and the fair market value at
the time the option is exercised. Options granted prior to February 17, 1993 are
not subject to the deduction limitation under this law.
 
    "Performance based" compensation is excluded from compensation counted
toward the $1 million deduction limit if certain conditions are met.
Compensation resulting from the exercise of stock options will be treated as
"performance based" and excluded from the limit on deductibility if among other
things, the plan under which the options are granted specifies limits on the
number of shares issuable to any participant in any one year under the plan and
these limits are approved by the issuer's shareholders.
 
    In order to exclude from the $1 million deduction limit compensation
resulting from the exercise of options granted under the 1993 Stock Plan, the
Board of Directors adopted, subject to shareholder approval, an amendment to the
plan to limit the number of shares with respect to which options may be granted
to no more than 500,000 shares to any one participant in any one-year period.
 
    APPROVAL OF AMENDMENTS.  The requirements for shareholder approval of
amendments to the 1993 Stock Plan reflect the requirements of old Rule 16b-3 of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Rule 16b-3
was amended in August 1996 to eliminate the requirement of shareholder approval
of plans (or amendments to plans) previously necessary to exempt grants of
options or purchase rights to directors and officers from the short-swing
liability provisions of Section 16 the Exchange Act. Consistent with the old
Rule 16b-3, the 1993 Stock Plan currently requires shareholder approval for any
amendment which increases the number of shares of Common Stock available for
issuance, materially changes the class of persons who are eligible for grants,
or materially increases the benefits under the plan. The Board has adopted,
subject to shareholder approval, an amendment to modify the requirement of
shareholder approval for future amendments to require such approval where (a)
required by Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), for incentive stock options, (b) required by other applicable laws,
regulations or rules (such as stock exchange rules), or (c) otherwise deemed
advisable by the Board. Under Rule 422 of the Code, shareholder approval would
continue to be required to increase the number of shares of Common Stock
available for issuance under the 1993 Stock Plan.
 
DESCRIPTION OF THE 1993 STOCK PLAN
 
    Under the 1993 Stock Plan, options or purchase rights may be granted to
officers (including officers who are also directors), employees and consultants
of Affymetrix, or a parent or subsidiary of Affymetrix, as selected from time to
time by the Board or a committee selected by the Board (the "Administrator"). An
option granted under the 1993 Stock Plan may be an incentive stock option (an
"ISO") within the meaning of Section 422 of the Code, or a nonstatutory stock
option (a "NSO").
 
    The option exercise price per share may not be less than the fair value of
the Common Stock on the grant date. Payment for shares purchased pursuant to
options may be made in cash, by check or by delivery, at the discretion of the
Administrator, of shares of Common Stock held for at least six months. In
addition, in the discretion of the Administrator, payment may be made by means
of an interest-bearing, full recourse promissory note.
 
                                       5
<PAGE>
    If authorized by the Administrator, exercise of an option may be made
through a "cashless exercise/ sale," in which the funds to pay for the exercise
of the option are delivered to the Company by a broker upon receipt of the stock
certificates representing shares of Stock or pursuant to which participants
obtain margin loans from brokers to fund the exercise of the option.
 
    Options will become exercisable at the times and subject to the conditions
prescribed by the Administrator. Options granted under the 1993 Stock Plan must
be exercised while the holder is an officer, director, employee or consultant of
Affymetrix, except that options may be exercised up to one year after the
holder's death or disability and within three months after termination of
employment or service for other reasons. Options are nontransferable except by
will, by the laws of descent and distribution, or pursuant to a qualified
domestic relations order, and are exercisable, during the holder's lifetime,
only by the holder. The term of any option will be fixed by the Administrator
but may not exceed ten years.
 
    The Administrator may grant purchase rights, providing for the direct sale
of Stock to eligible participants. As soon as practicable after the grant date,
the Administrator will advise the holder of the Purchase Rights of the terms of
the grant, including the number of shares of Common Stock covered by the
purchase right, the purchase price and the exercise period. The purchase price
of a purchase right shall be at least 85% of the fair market value of the shares
of Stock on the date the purchase right is granted or on the date the Stock is
purchased. If, at the time the Company grants a purchase right, the purchaser is
a 10% Shareholder, the purchase price shall be at least 100% of the fair market
value of the shares of Common Stock on the date the purchase right is granted or
on the date the Common Stock is purchased.
 
    Upon issuance or transfer of Common Stock pursuant to the exercise of an
option or purchase right, Affymetrix has the right to require the recipient to
remit to Affymetrix in cash any withholding tax requirements for such shares. To
the extent authorized by the Administrator, in its sole discretion, the
recipient may elect to surrender or authorize Affymetrix to withhold shares of
Common Stock in satisfaction of his or her estimated withholding tax obligations
or to deliver an interest-bearing full recourse promissory note.
 
    The 1993 Stock Plan will terminate on July 1, 2003 and no option or purchase
right may be granted under the 1993 Stock Plan after that date. Options and
purchase rights granted before termination of the 1993 Stock Plan will remain
exercisable thereafter until they expire or lapse according to their terms.
 
FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a general summary of the typical federal income tax
consequences to a 1993 Stock Plan participant who is a citizen or resident of
the United States. It does not describe state or other tax consequences.
 
    The grant of an ISO generally has no federal income tax effect on the
optionee. Upon exercise, the optionee does not recognize income for "regular"
tax purposes; however, the "option spread" (the excess of the fair market value
of the option shares over the exercise price) is includable in the optionee's
"Alternative Minimum Taxable Income (AMTI)" for purposes of the Alternative
Minimum Tax. However, if the purchased shares are subject to the right to
repurchase by the Company and the participant does not make an election to be
taxed on the option spread at the time of the exercise of the ISO, the option
spread will not be measured or includable in AMTI until the right to repurchase
has lapsed. If the optionee does not dispose of the option shares until more
than two years after the option grant date and one year after exercise of the
option, gain upon sale of the shares will be taxable as long-term capital gain.
If shares are sold or otherwise disposed of before either of these periods have
expired (a "disqualifying disposition"), the option spread at the time of
exercise (but not more than the amount of gain on the sale) is ordinary income
in the year of sale. Any increase between the value of the shares on the date of
exercise and the date of sale is taxable as capital gain which would be
long-term if the shares have been held more than one year after the date of
exercise. The Company is not entitled to a federal income tax deduction in
 
                                       6
<PAGE>
connection with ISOs, except to the extent that the optionee recognizes ordinary
income on a disqualifying disposition.
 
    The grant of a NSO generally has no federal income tax effect on the
optionee. Upon exercise, the optionee generally has taxable ordinary income (and
the Company realizes a corresponding deduction) equal to the spread between the
fair market value of the stock on the date of exercise and the exercise price.
The Company is required to withhold federal (and state) income and employment
taxes on that income upon exercise. However, if the purchased shares are subject
to a right to repurchase and the participant does not make an election to be
taxed on the spread at the time of the exercise of the NSO, the spread will not
be measured or includable in taxable income until the right to repurchase has
lapsed. Upon the disposition of the shares, the participant has taxable
long-term or short-term capital gain or loss, depending on how long the shares
were held.
 
    Special federal income tax rules apply if the exercise price is paid with
stock, or if the shares are subject to a "substantial risk of forfeiture."

(1) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission. In computing the number of Shares
    beneficially owned by a person and the percentage of ownership of that

    are currently exercisable or exercisable within 60 days of March 31, 1997
    are deemed outstanding. Such shares, however, are not deemed outstanding for
    the purpose of computing the percentage ownership of each other person. The
    persons named in this table have sole voting and investment power with
    respect to all shares of Common Stock shown as beneficially owned by them,
    subject to community property laws where applicable and except as indicated
    in the other footnotes to this table.

                        COMPENSATION COMMITTEE REPORT(1)
 
    The Compensation Committee (the "Committee") of the Board of Directors is
generally responsible for the design, structure and administration of the
executive officers' compensation program. The Committee reviews the salary and
stock option award recommendations of the President (other than for himself)
along with the basis for such recommendations including performance reviews and
competitive base salary data. The Committee has separately evaluated the
performance during 1996 of the Company's Chairman and Chief Executive Officer,
Dr. Diekman, and President and Chief Operating Officer, Dr. Fodor. In
determining compensation policies, the Committee reviews compensation and
benefits surveys for regional biotechnology companies which compete with the
Company in the recruitment of senior personnel. The Committee consists of three
non-employee directors.
 
COMPENSATION POLICIES
 
    The Committee bases its decisions on Affymetrix's executive compensation
philosophy, which seeks to relate salaries and stock option awards to
Affymetrix's success in meeting annual and long-term performance goals, to
reward individual achievement and to attract and retain qualified executives.
Affymetrix seeks to set its executive officers' salaries in the mid-range
compared to those with similar management positions in peer companies consisting
primarily of regional biotechnology companies. The level of salaries paid to
executive officers of the Company also takes into account the technological
achievements of the Company during the year, its success in entering into
significant technology agreements with collaborators, as well as an evaluation
of the individual performance and contribution of each executive to the
Company's

related disclosure is not soliciting material, is not deemed filed with the SEC,

performance for the year. The Committee particularly considers the individual
officer's level of responsibility for and role in meeting the Company's
strategic, technological, and financial objectives. The Committee has not used
either the profitability of the Company or the market value of its stock as
significant factors in consideration for setting executive officer salaries.
Consistent with these policies, the Committee set executive officers' salaries
for 1996 in the mid-range as compared to other regional biotechnology companies.
 
    Stock options awards are intended to align the interests of executives with
the interests of the shareholders in the long-term performance of the Company.
Guidelines for executive stock option awards have been developed by the
Committee through analysis of long-term incentive awards based on each
individual executive's position, responsibilities, performance and contribution
to the achievement of the Company's long-term goals and competitive stock option
data from regional biotechnology companies. In addition, the Committee reviews
the equity position of all executive officers on an annual basis and awards
stock options to executive officers periodically.
 
CHIEF EXECUTIVE OFFICER'S COMPENSATION
 
    The 1996 compensation of Dr. John D. Diekman, the Company's Chairman and
Chief Executive Officer took into account the above policies and specific
milestones achieved by the Company during the year. These milestones included
the successful completion of the Company's 1995 private financing, forming
collaborative alliances with biotechnology, pharmaceutical and genomics
companies and the progress toward the introduction of the Company's first
commercial product. The Committee believes that Dr. Diekman's salary of $232,458
for 1996 was in the mid-range compared to CEOs in peer companies consisting
primarily of regional biotechnology companies.
 
SECTION 162(M) COMPLIANCE
 
    Section 162(m) of the Internal Revenue Code (the "Code") limits the Company
to a deduction for federal income tax purposes of no more than $1 million of
compensation paid to certain Named Executive Officers in a taxable year.
Compensation above $1 million may be deducted if it is "performance-based
compensation" within the meaning of the Code.
 
    The Compensation Committee has determined that stock options granted under
the Company's 1993 Stock Plan with an exercise price 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." As a result, the Company's shareholders
have been asked to approve an amendment to the 1993 Stock Plan which would allow
any compensation recognized by a Named Executive Officer as a result of the
grant of such a stock option to be deductible by the Company.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Compensation Committee is responsible for determining salaries,
incentives and other forms of compensation for officers and other employees of
the Company and administers various incentive compensation and benefit plans.
The Compensation Committee consists of Paul Berg, John A. Young and Alejandro C.
Zaffaroni. Stephen P.A. Fodor, President and Chief Executive Officer of the
Company, participates in all discussions and decisions regarding salaries and
incentive compensation for all employees and consultants of the Company, except
that Dr. Fodor is excluded from discussions regarding his own salary and
incentive compensation.

                              CERTAIN TRANSACTIONS
 
    In July 1995, the Company and Glaxo Wellcome entered into an agreement (the
"Governance Agreement") pursuant to which Glaxo Wellcome has the right to
designate a number of directors based on the percentage of voting stock then
held directly or indirectly by Glaxo Wellcome and is obligated to vote its
shares for the slate of directors recommended to the shareholders. Glaxo
Wellcome currently has the right to designate three of the ten directors of the
Company. Pursuant to the Governance Agreement, Glaxo Wellcome also agreed that
any merger, consolidation or business combination whereby the Company would
become a direct or indirect wholly-owned subsidiary of Glaxo Wellcome and any
material transaction between the Company and Glaxo Wellcome must be approved by
a majority of the independent directors of the Company. In addition, pursuant to
the Governance Agreement, the Company granted Glaxo Wellcome certain
registration rights with respect to its shares.
 
    In May 1996, the Company entered into an agreement with Glaxo Wellcome to
develop and supply probe arrays to detect polymorphisms in specific genes. The
agreement, which has a term of up to three years, provides for development
funding and milestone payments upon achievement of certain technical goals. For
the year ended December 31, 1996, the Company received payments totaling $70,000
from Glaxo Wellcome under the agreement.
 
    In January 1997, the Company entered into a HIV database agreement with
Glaxo Wellcome. Under the terms of the Agreement, Affymetrix and Glaxo Wellcome
will work together to build a database to understand the correlation between
mutations in HIV and response to antiviral drugs. Glaxo Wellcome will pay all
costs of the project, which has an estimated term of three years.
 
    In February 1997, the Company entered into an agreement with Affymax and
several of its affiliated entities that supersedes the technology license
agreement between the Company and Affymax entered into in 1993. Under the terms
of the agreement, which was effective as of 1995, Affymax assigned to the
Company all rights in patents relating to light directed synthesis technologies
and probe array technologies. The Company's license rights in certain
technologies, including "encoded synthetic library" technology, were terminated.
The Company retains or was assigned rights to use certain trademarks, including
"Affymetrix."
 
    The Company and Affymax Research Institute, a subsidiary of Affymax ("ARI"),
entered into a Services Agreement dated October 1, 1993, pursuant to which ARI
agreed to perform certain administrative and management services for the
Company. For the year ended December 31, 1996, the Company's expenses for
services performed by Affymax were in the amount of $95,000. John D. Diekman is
a director of ARI.
 
    In February 1994, the Company entered into a sublease agreement with Affymax
providing for the Company to sublease facilities in Santa Clara, California from
Affymax until October 1, 1995. In April 1995, the Company exercised an option to
extend the sublease to October 1, 1996. For the year ended December 31, 1996,
the Company's expenses under the sublease agreement were $534,000. In May 1996,
the Company canceled the sublease with Affymax and is directly leasing the
facility from a third party.
 
    The Company believes that its agreements with Affymax are on terms no less
favorable to the Company than would be obtained from unaffiliated third parties.
 
    In February 1996, the Company and Symyx, Inc. ("Symyx") entered into a
sublease agreement at market rates for a portion of the property leased to the
Company in Sunnyvale, California. For the year ended December 31, 1996, Symyx
paid the Company $152,128 under this sublease. Kenneth J. Nussbacher is a
director, and Alejandro C. Zaffaroni is a director and greater than 10%
stockholder, of Symyx.
 
    In November 1994, the Company agreed to guarantee a loan in the amount of
$117,000 of Stephen P.A. Fodor. As of March 31, 1997, the full amount of the
loan remained outstanding.
 
                                       16
<PAGE>
    In April 1997, the Company made a $500,000 secured loan to Dr. Fodor to
assist him in purchasing a principal residence. The loan bears an interest rate
of 6.49% and is due on the first to occur of April 11, 2002, the sale of the
house, or termination of Dr. Fodor's employment.
 
    In June 1995, the Company entered into an agreement with David B. Singer in
connection with his resignation as President and Chief Executive Officer and
assumption of the position of Vice Chairman of the Board. Pursuant to the
agreement, the Company relinquished its right to repurchase any of the 133,333
shares of Common Stock acquired by Mr. Singer in December 1993, amended the
option to purchase 100,000 shares granted to Mr. Singer in December 1994 to
fully vest 50,000 shares as of September 1995, and waived its right to demand
repayment of a secured promissory note in the principal amount of $40,000,
evidencing a loan made to Mr. Singer in December 1993 to enable him to purchase
133,000 shares of Common Stock until July 1998. The loan bears interest at the
rate of 5.07% per annum. Pursuant to the agreement, Mr. Singer agreed to
continue to serve as a Director of the Company if nominated and elected by the
shareholders, to serve as Vice Chairman of the Board, and to provide consulting
services to the Company relating to the financing of the Company, grants and
government relations. During the year ended December 31, 1996, Mr. Singer
received payments totalling $175,000 pursuant to the agreement.
 
    The Company has entered into indemnification agreements with each of its
directors and executive officers. Such agreements require the Company to
indemnify such persons to the fullest extent permitted by California law.

to administer this Plan. Any decision or action of the Administrator in
connection with this Plan or any Options or Purchase Rights granted or shares of
Stock purchased under this Plan shall be final and binding. The Administrator
shall not be liable for any decision, action or omission respecting this Plan,
or any Options or Purchase Rights granted or shares of Stock sold under this
Plan. The Board at any time may abolish the committee and revest in the Board
the administration of the Plan.
 
    5.  PERSONS ELIGIBLE TO PARTICIPATE IN THIS PLAN.  Options and Purchase
Rights may be granted under this Plan to officers, key employees, consultants
and directors of the Company, or a Parent or a Subsidiary.
 
    6.  GRANT OF OPTIONS; TERMS AND CONDITIONS OF GRANT.
 
        (a)  GRANT OF OPTIONS.  The Administrator may, in its absolute
    discretion, grant Options under this Plan at any time and from time to time
    before the expiration of ten years from the Effective Date. The
    Administrator shall specify the type of Option, the Grant Date, the number
    of shares of Stock covered by the Option, the exercise price and the terms
    and conditions for exercise of the Option. If the Administrator fails to
    specify the Grant Date, the Grant Date shall be the date of the action taken
    by the Administrator to grant the Option. Notwithstanding the foregoing, if
    an Incentive Stock Option is approved in anticipation of employment of any
    employee, the Grant Date shall be the date the intended Optionee is first
    treated as an employee of the Company, or a Parent or a Subsidiary, for
    payroll purposes. As soon as practicable after the Grant Date, the Company
    will provide the Optionee with a written Option Agreement in the form
    approved by the Administrator, which sets forth the type of Option, the
    Grant Date, the number of shares of Stock covered by the Option, the
    exercise price and the terms and conditions for exercise of the Option.
 
                                       3
<PAGE>
        (b)  TERMS AND CONDITIONS OF GRANT.  Options granted under this Plan
    shall be subject to the following terms and conditions and such other terms
    and conditions not inconsistent with this Plan as the Administrator may
    impose:
 
            (i) TYPE OF OPTION. Any Option granted under the Plan shall be in
       such form as the Administrator may from time to time approve. Incentive
       Stock Options may be granted only to employees of the Company, or a
       Parent or a Subsidiary. Subject to the foregoing, the Administrator shall
       have the authority to grant to any participant Incentive Stock Options,
       Nonqualified Stock Options or both types of Options. Any portion of an
       Option that is not designated as, or does not qualify as, an Incentive
       Stock Option, shall constitute a Nonqualified Stock Option.
 
            (ii) EXERCISE OF OPTION. In order to exercise all or any portion of
       any Option granted under this Plan, an Optionee must remain as an
       officer, employee, consultant or director of the Company, or a Parent or
       a Subsidiary, until the Vesting Date. The Option shall be exercisable on
       or after each Vesting Date in accordance with the terms set forth in the
       Option Agreement.
 
    Notwithstanding any designation of an Option as an Incentive Stock Option,
to the extent that exercisability of any Incentive Stock Option granted under
this Plan or otherwise to the Optionee by the Company, or a Parent or a
Subsidiary, would result in an Optionee being able to exercise for the first
time in any calendar year Incentive Stock Options to purchase shares of Stock
having a fair market value (determined as of the Grant Date) in excess of
$100,000, the excess above $100,000 determined in reverse order of the Grant
Date shall be automatically converted to a Nonstatutory Stock Option.
Notwithstanding the foregoing, the Administrator in its absolute discretion may
elect a different order for determining which Incentive Stock Option shall
automatically be converted to a Nonstatutory Stock Option or may determine to
defer the exercisability of an Incentive Stock Option or portion of an Incentive
Stock Option so that in no event will Incentive Stock Options for Stock having a
fair market value in excess of $100,000 (determined as of the Grant Date) become
exercisable for the first time in any calendar year.
 
           (iii) OPTION TERM. The term of any Option shall be fixed by the
       Administrator, but no Incentive Stock Option granted under this Plan may
       be exercised more than ten years from the Grant Date. If, at the time the
       Company grants an Option, the Optionee directly or by attribution owns
       stock possessing more than 10% of the total combined voting power of all
       classes of stock of the Company, or a Parent or a Subsidiary, the Option
       shall not be exercisable more than five years after the Grant Date.
 
           (iv) EXERCISE PRICE. The exercise price shall be at least 100% of the
       fair market value of the shares of Stock covered by the Option on the
       Grant Date, as determined in good faith by the Administrator. If, at the
       time the Company grants an Option, the Optionee directly or by
       attribution owns stock possessing more than 10% of the total combined
       voting power of all classes of stock of the Company, or a Parent or a
       Subsidiary, the exercise price shall be at least 110% of the fair market
       value of the shares of Stock covered by the Option on the Grant Date
       determined in the same manner.
 
            (v)  METHOD OF EXERCISE. To the extent the right to purchase shares
       of Stock has accrued, Options may be exercised, in whole or in part, from
       time to time in accordance with their terms by written notice from the
       Optionee to the Company stating the number of shares of Stock with
       respect to which the Option is being exercised and accompanied by payment
       in full of the exercise price. Payment may be made in cash, by check or
       by delivery, at the absolute discretion of the Administrator, of shares
       of Stock held by the Optionee. If authorized by the Administrator,
       exercise of an Option may be made pursuant to a "cashless exercise sale"
       procedure, pursuant to which funds to pay for exercise of the Option are
       delivered to the issuer by a broker upon receipt of stock certificates
       from the issuer, or pursuant to which participants obtain margin loans
       from brokers to fund the exercise of the Option. In the absolute
       discretion of the Administrator,
 
                                       4
<PAGE>
       payment may be made by delivery of an interest-bearing, full recourse
       promissory note. In the discretion of the Administrator, the exercise
       price may be paid by a combination of the above.
 
            (vi) OPTION AGREEMENT. The terms and conditions of each option shall
       be set forth in the Option Agreement evidencing the Option. No Option
       shall be exercisable until after execution of the Option Agreement by the
       Company and the Optionee.
 
            (vii) NONASSIGNABILITY OF OPTION RIGHTS. No Option shall be
       transferable other than by will or by the laws of descent and
       distribution or pursuant to a Qualified Domestic Relations Order. During
       the lifetime of an Optionee, only the Optionee may exercise an Option.
 
           (viii) EXERCISE AFTER TERMINATION OF EMPLOYMENT OR DEATH. If for any
       reason other than permanent and total disability or death an Optionee
       ceases to be employed by the Company, or a Parent or a Subsidiary, in the
       case of an Incentive Stock Option or to be employed by or to be a
       consultant or director of the Company, or a Parent or a Subsidiary, in
       the case of a Nonstatutory Stock Option, Options held at the date of such
       termination (to the extent then exercisable) may be exercised, in whole
       or in part, at any time within 3 months after the date of such
       termination or such lesser period of not less than 30 days specified in
       the Option Agreement, but in no event after the earlier of (i) the
       expiration date of the Option as set forth in the Option Agreement, and
       (ii) ten years from the Grant Date. If an Optionee becomes permanently
       and totally disabled (within the meaning of Section 22(e)(3) of the Code)
       or dies while employed by the Company, or a Parent or a Subsidiary, (or,
       if the Optionee dies within the period that the Option remains
       exercisable after termination of employment), Options then held (to the
       extent then exercisable) may be exercised by the Optionee, the Optionee's
       personal representative, or by the person to whom the Option is
       transferred by will or the laws of descent and distribution or pursuant
       to a Qualified Domestic Relations Order, in whole or in part, at any time
       within one year after the disability or death or any lesser period of not
       less than 6 months specified in the Option Agreement, but in no event
       after the earlier of (i) the expiration date of the Option as set forth
       in the Option Agreement and (ii) ten years from the Grant Date.
 
            (ix) COMPLIANCE WITH SECURITIES LAWS. The Company shall not be
       obligated to issue any shares of Stock upon exercise of an Option except
       in compliance with all applicable securities laws and the regulations of
       any stock exchange on which the Company's securities may then be listed.
       Evidences of ownership of shares of Stock acquired upon exercise of
       Options shall bear any legend required by, or useful for purposes of
       compliance with, applicable securities laws, this Plan or the Option
       Agreement evidencing the Option.
 
    7.  PURCHASE RIGHTS.
 
        (a)  GRANT.  As soon as practicable after the Grant Date of a Purchase
    Right, the Administrator shall advise the holder of such right in writing of
    the terms, conditions and restrictions relating to the grant, including the
    number of shares of Stock covered by the Purchase Right, the purchase price,
    and the time within which the Purchase Right must be exercised.
 
        (b)  PURCHASE PRICE.  The purchase price of a Purchase Right shall be at
    least 85% of the fair market value of the shares of Stock on the Grant Date
    or on the date the Stock is purchased, as determined in good faith by the
    Administrator. If, at the time the Company grants a Purchase Right, the
    purchaser directly or by attribution owns stock possessing more than 10% of
    the total combined voting power of all classes of stock of the Company, or a
    Parent or a Subsidiary, the purchase price shall be at least 100% of the
    fair market value of the shares of Stock on the Grant Date or on the date
    the Stock is purchased, determined in the same manner.
 
        8.  PAYMENT OF TAXES.  Unless the Administrator permits otherwise, the
    participant shall pay the Company in cash, promptly when the amount of such
    obligations becomes determinable (the "Tax Date"), all applicable local,
    state and federal withholding taxes applicable, in the Administrator's
 
                                       5
<PAGE>
    absolute discretion, to (i) the exercise of any Option or Purchase Right, or
    (ii) the transfer or other disposition of shares acquired upon exercise of
    any Option or Purchase Right.
 
    If and to the extent authorized by the Administrator in its absolute
discretion, a participant may make an election to (x) deliver to the Company a
promissory note of the participant on the terms set forth in Section 6(b)(v),
(y) tender shares of Stock to the Company or (z) have shares of Stock or other
securities of the Company withheld by the Company, to pay the amount of tax that
the Administrator in its absolute discretion determines to be required to be
withheld by the Company.
 
    Any shares of Stock so withheld or tendered shall be valued by the Company
at their fair market value on the Tax Date. The right to so withhold or tender
shares of Stock shall relate separately to each Option or Purchase Right or any
increment thereof covering not less than 100 shares of Stock.
 
    9.  ADJUSTMENT FOR CHANGES IN CAPITALIZATION.  The existence of outstanding
Options shall not affect the Company's right to effect adjustments,
recapitalizations, reorganizations or other changes in its or any other
corporation's capital structure or business, any merger or consolidation, any
issuance of bonds, debentures, preferred or prior preference stock ahead of or
affecting the Stock, the dissolution or liquidation of the Company's or any
other corporation's assets or business or any other corporate act whether
similar to the events described above or otherwise. Subject to Section 10, if
the outstanding shares of the Stock are increased or decreased in number or
changed into or exchanged for a different number or kind of securities of the
Company or any other corporation by reason of a recapitalization,
reclassification, stock split, combination of shares, stock dividend or other
event, the number and kind of securities with respect to which Options may be
granted under this Plan, the number and kind of securities as to which
outstanding Options may be exercised, and the exercise price at which
outstanding Options may be exercised, shall be adjusted, to the extent possible,
so as to prevent dilution and without regard to any resulting tax consequences
to the Optionee.
 
    10.  DISSOLUTION, LIQUIDATION, MERGER.  In the event of a dissolution or
liquidation of the Company, a merger in which the Company is not the surviving
corporation, or a sale of over 80% of the assets of the Company, the
Administrator, in its absolute discretion, may cancel each outstanding Option
upon payment in cash to the Optionee of the amount by which any cash and the
fair market value of any other property which the Optionee would have received
as consideration for the shares of Stock covered by the fully-vested portion of
the Option if the Option had been exercised before such liquidation,
dissolution, merger, or sale exceeds the exercise price of the Option.
 
    11.  SUCCESSOR CORPORATIONS.  In the event of a merger in which the Company
is not the surviving corporation, the successor entity may assume the
obligations under all outstanding Options.
 
    12.  NO RIGHTS AS SHAREHOLDER OR TO CONTINUED EMPLOYMENT.  An Optionee shall
have no rights as a shareholder with respect to any shares of Stock covered by
an Option until such Optionee has acquired title to such shares. Subject to
Sections 9 and 10, no adjustment shall be made for dividends or other rights for
which the record date is prior to the date title to the shares of Stock has been
acquired by the Optionee. The grant of an Option shall in no way be construed so
as to confer on any Optionee the right to continued employment by the Company,
or a Parent or a Subsidiary.
 
    13.  DISQUALIFYING DISPOSITIONS.  If Stock acquired upon exercise of an
Option is disposed of in a disqualifying disposition within the meaning of
Section 422 of the Code, the holder of the shares of Stock immediately prior to
the disposition shall notify the Company in writing of the date and the terms of
such disposition and comply with any other requirements imposed by the Company
in order to enable the Company to secure the related income tax deduction to
which it is entitled.
 
    14.  TERMINATION; AMENDMENT.  The Board may amend, suspend or terminate this
Plan at any time and for any reason, but no amendment, suspension or termination
shall be made which would impair the right of any person under any outstanding
Options or Purchase Rights without such person's consent. No amendment shall
require shareholder approval unless (a) shareholder approval is required by
Section 422
 
                                       6
<PAGE>
of the Code (for Incentive Stock Options); (b) shareholder approval is required
by other applicable laws, regulations or rules; or (c) the Board otherwise
concludes that shareholder approval is advisable.
 
    15.  GOVERNING LAW.  This Plan and the rights of all persons under this Plan
shall be construed in accordance with and under applicable provisions of the
Code and the laws of the State of California.
