        A.      GENERAL PLAN INFORMATION.

                The Plan's purpose is to provide, through the grant of
nonstatutory options (which are not intended to be incentive stock options
within the meaning of Section 422(b) of the Code), an incentive to attract,
retain and reward persons performing services for the participating company
group and to motivate such persons to contribute to its growth and
profitability. The Board adopted the Plan on February 6, 1996. No stockholder
approval is required. The Plan will continue in effect until the earlier of its
termination by the Board or the date all shares available for issuance under the
Plan have been issued and all restrictions on such shares have lapsed.

        Should any inconsistency exist between the following description and the
actual terms of the Plan or the optionee's agreement, the terms of the Plan or
the optionee's agreement control.

        B.      PLAN ADMINISTRATION.

                (1)     General. The Plan is administered by the Board,
including any duly appointed committee of the Board. All questions of
interpretation of the Plan or of any option are determined by the Board, and
such determinations are final and binding. Communications to the Board may be
addressed to the Company's principal executive offices at 894 Ross Drive,
Sunnyvale, CA 94089, 408/541-1500.

                (2)     Composition of Board. Directors are elected for
three-year terms. The directors are divided into three classes, with one class
elected at each annual meeting of stockholders. All directors will hold office
until the expiration of the term for which elected and until their successors
are elected and qualified or until their earlier death, resignation or removal
from office. The entire Board or any individual director may be removed from
office, prior to the expiration of a Board member's term of office, only in the
manner and within the limitations provided by the Bylaws of the Company and the
law of Delaware.

                (3)     Powers of the Board. In addition to any other powers in
the Plan and subject to the provisions of the Plan, the Board (a) determines the
persons to whom, and the time or times at which, options will be granted and the
number of shares subject to each option; (b) determines the fair market value of
shares or other property; (c) determines the terms, conditions and restrictions
consistent with the terms of the Plan applicable to each option (which need not
be identical) and any acquired shares; (d) may approve one or more forms of
option agreement; (e) may amend, modify, extend, or renew, or grant a new option
in substitution for, any option or waive any restrictions or conditions
applicable to any option or any acquired shares; (f) may accelerate, continue,
extend or defer the exercisability of any option or the vesting of any shares
acquired upon the exercise thereof, including with respect to the period
following an optionee's termination of employment or service with the
participating company group; (g) may prescribe, amend or rescind rules,
guidelines and policies relating to the Plan, or adopt supplements to, or
alternative versions of, the Plan; and (h) may correct any defect, supply any
omission or reconcile any inconsistency in the Plan or any option agreement and
make all other determinations and take such other actions with respect to the
Plan or any option to the extent consistent with the Plan and applicable law.

                (4)     Share Reserve and Capital Changes. A maximum aggregate
of 4,210,000 shares may be issued under the Plan. If there is a stock dividend,
stock split, reverse stock split, recapitalization,


   3
combination, reclassification or similar change in the capital structure of the
Company, appropriate adjustments will be made in the number and class of shares
subject to the Plan and to any outstanding options, as well as in the exercise
price per share of any outstanding options.

        C.      ELIGIBILITY.

                One or more options may be granted to employees and consultants
(but not to insiders) of the participating company group. Options also may be
granted to prospective employees and consultants in connection with written
offers of employment or engagement.

        D.      GRANT OF OPTION.

                Options are evidenced by option agreements specifying the number
of shares covered in a form established by the Board, subject to the following
terms and conditions:

                (1)     Exercise Price. The exercise price per share may not be
less than 85% of the fair market value of a share on the option grant date, as
determined by the Board (generally the closing price of the common stock of the
Company on the Nasdaq National Market).

                (2)     Right to Exercise. Generally, an option may be exercised
at any time after its grant and prior to its termination, subject to the
Company's right to repurchase any unvested shares held by the optionee at the
time of the optionee's termination of service or if the optionee attempts to
dispose of unvested shares. (An option granted to a prospective employee or
consultant cannot be exercised before the optionee commences service with a
participating company.) However, the option may not be exercised more frequently
than twice in any continuous 12 month period, although this restriction will not
prevent an exercise (a) following the optionee's termination of service or (b)
during the 30 day periods immediately preceding and following an "ownership
change event" described below. To ensure that unvested shares or shares securing
any promissory note will be available for repurchase, the Company may require
the optionee to deposit the certificate evidencing the shares with an agent
designated by the Company under the terms and conditions of escrow and security
agreements approved by the Company.

                (3)     Vesting Schedule. The vesting schedules of option
agreements need not be identical. However, provided the optionee has
continuously rendered service to the participating company group, the normal
vesting schedule is as follows:



                                                                       Vested Shares
                                                                       -------------
                                                                    
                        6 months after grant of the option................12.50%
                        Plus, for each full month thereafter
                        of optionee's continuous service.................. 2.08%


                (4)     Tax Withholding. The Company may deduct from the shares
issuable upon the exercise of an option, or accept from the optionee the tender
of, a number of whole shares having a fair market value equal to all or any part
of any taxes required to be withheld by the participating company

   4
group. Alternatively or in addition, the Company may require the optionee to
make adequate provision for such tax withholding obligations. The Company is not
obliged to deliver shares or to release shares from any escrow until such tax
withholding obligations have been satisfied.

                (5)     Term of Option. An option terminates and may not be
exercised after the earlier of (a) the option expiration date stated in an
optionee's agreement (generally 10 years), (b) as to unvested shares,
immediately upon the optionee's termination of service for any reason, (c) as to
vested shares, six months after the optionee's termination of service due to
death or disability or one month after the optionee's termination of service for
any other reason, or (d) a "transfer of control" as described below unless the
option is assumed or substituted for by the acquiring corporation.

                (6)     Leave of Absence. The optionee's service with the
participating company group will not be deemed to terminate if the optionee
takes any military leave, sick leave, or other bona fide leave of absence
approved by the Company of 90 days or less. If a leave of absence in excess of
90 days, the optionee's service will terminate on the 91st day of such leave
unless the optionee's right to reemployment with the participating company group
remains guaranteed by statute or contract. Unless otherwise designated by the
Company (or required by law), a leave of absence will not be treated as service
for vesting purposes.

                (7)     Extension of Option Term. If exercise is prevented
because the issuance of shares would violate any law or regulation, the option
is exercisable until the earlier of the option's expiration date or three months
after the optionee is notified by the Company that the option is again
exercisable. If a sale of shares during the time limits for exercise following
termination of service would subject the optionee to suit under Section 16(b) of
the Exchange Act ("Section 16(b)"), the option will remain exercisable until the
earlier of the option's expiration date, 10 days after the optionee is no longer
subject to such suit, or 190 days after the optionee's termination of service.

                (8)     Rights as a Stockholder, Employee or Consultant. An
optionee will have no rights as a stockholder with respect to any shares until
issued a share certificate. No adjustment will be made for dividends,
distributions, or other rights if the record date is prior to the date a
certificate is issued (except for capital changes described above). Nothing in
the Plan or an option gives an optionee any right to continue in the service of
a participating company or interferes with any right of the participating
company to terminate the optionee's service.

                (9)     Repurchase Rights. The shares may be subject to a right
of first refusal, one or more repurchase options, or other conditions and
restrictions determined by the Board at the time the option is granted. The
Company may assign any repurchase right it may have, whether or not such right
is then exercisable, to one or more persons selected by the Company. Upon
request by the Company, each optionee must execute an agreement evidencing such
transfer restrictions before receiving shares and must promptly present to the
Company share certificates to have appropriate legends evidencing such transfer
restrictions placed thereon.


   5
                (10)    Standard Form of Option Agreement. Unless otherwise
provided by the Board when the option is granted, an option must comply with and
be subject to the terms and conditions set forth in the form of Immediately
Exercisable Nonstatutory Stock Option Agreement adopted by the Board. The Board
may vary the terms of any standard form of option agreement either in connection
with the grant or amendment of an individual option or in connection with the
authorization of a new standard form and may grant options which are not
immediately exercisable.

        E.      OPTION EXERCISE AND PAYMENT FOR SHARES.

                (1)     Method of Exercise. Options are exercised by written
notice to the Company stating the election to exercise the option, the number of
whole shares for which the option is being exercised and such other
representations and agreements as to the optionee's investment intent required
by the option agreement. The written notice must be signed by the optionee and
delivered in person, by certified or registered mail, return receipt requested,
by confirmed facsimile transmission, or by such other means as the Company
permits, to the Stock Plan Administrator of the Company, or other authorized
representative of the participating company group, before the option terminates,
accompanied by full payment of the aggregate exercise price for the number of
shares being purchased and an executed copy, if required by the option
agreement, of the then current forms of escrow and security agreement.

                (2)     Payment. Generally the exercise price for the shares
being purchased may be paid by any combination of (1) cash, check, or cash
equivalent, (2) tender to the Company of shares owned by the optionee having a
fair market value not less than the exercise price, (3) the assignment of the
proceeds of a sale or loan with respect to some or all of the shares being
acquired upon the exercise of the option (a "cashless exercise"), or (4) payment
in cash of an amount not less than the par value of the shares being acquired
and the optionee's promissory note for the balance of the exercise price if
approved by the Company. The Board may grant options which do not permit all of
these forms of consideration, which restrict one or more such forms of
consideration, or which authorize other forms of lawful consideration.

                (3)     Limitations on Forms of Consideration. The forms of
consideration listed above are subject to several limitations, including the
following: (1) An option may not be exercised by tender to the Company of shares
to the extent such tender of shares would constitute a violation of the
provisions of any law, regulation or agreement restricting the redemption of the
Company's stock; (2) unless otherwise provided by the Board, an option may not
be exercised by tender to the Company of shares unless such shares either have
been owned by the optionee for more than six months or were not acquired,
directly or indirectly, from the Company; (3) the Company reserves the right to
establish, decline to approve or terminate any program or procedures for the
exercise of options by means of a cashless exercise; and (4) no payment in part
with a promissory note will be permitted if the exercise of an option using a
promissory note would be a violation of any law.

                (4)     Certificate Registration and Fractional Shares. Unless
the exercise price is paid by means of a cashless exercise, the certificate for
the shares acquired will be registered in the name of

   6
the optionee, or, if applicable, in the names of the heirs of the optionee. The
Company is not required to issue fractional shares.

                (5)     Restrictions on Grant of the Option and Issuance of
Shares. The grant of the option and the issuance of shares are subject to
compliance with all applicable requirements of law. The option may not be
exercised if the issuance of such shares would violate any applicable securities
laws or other law or regulations or the requirements of any stock exchange or
market system upon which the shares are then listed. In addition, the option may
not be exercised unless a registration statement under the Securities Act is
then in effect with respect to the shares to be acquired or, in the opinion of
legal counsel to the Company, the such shares may be issued in accordance with
the terms of an applicable exemption from the registration requirements of the
Securities Act.

        F.      NONTRANSFERABILITY.

                Only the optionee (or the optionee's guardian or legal
representative) may exercise an option during the optionee's lifetime. The
option is not assignable or transferable except by will or by the laws of
descent and distribution.

        G.      TRANSFER OF CONTROL.

                If a "transfer of control" of the Company occurs, the surviving,
continuing, successor, or purchasing corporation or parent corporation thereof,
as the case may be (the "acquiring corporation"), may either assume the
Company's rights and obligations under outstanding options or substitute for
outstanding options substantially equivalent options for the acquiring
corporation's stock. Generally any options which are not assumed, substituted
for or exercised will terminate as of the date of the transfer of control.

                A "transfer of control" means an "ownership change event" (as
defined below) or a series of related ownership change events (collectively, the
"transaction") wherein the stockholders of the Company immediately before the
transaction do not retain immediately after the transaction, in substantially
the same proportions as their ownership of shares of the Company's voting stock
immediately before the transaction, direct or indirect beneficial ownership of
more than 50% of the total combined voting power of the outstanding voting stock
of the Company or the corporation or corporations to which the assets of the
Company were transferred, as the case may be. An "ownership change event" is
deemed to have occurred if any of the following occurs with respect to the
Company: (1) the direct or indirect sale or exchange in a single or series of
related transactions by the stockholders of the Company of more than 50% of the
voting stock of the Company; (2) a merger or consolidation in which the Company
is a party; (3) the sale, exchange, or transfer of all or substantially all of
the assets of the Company; or (4) a liquidation or dissolution of the Company.

        H.      AMENDMENT OR TERMINATION OF THE PLAN.

                The Board may terminate or amend the Plan at any time but may
not adversely affect any then outstanding option or any unexercised portion
thereof, without the consent of the optionee, unless the termination or
amendment is necessary to comply with an applicable law or government
regulation.


   7
        I.      ERISA AND INTERNAL REVENUE CODE SECTION 401.

                The Plan is not subject to the provisions of the Employee
Retirement Income Security Act of 1974, as amended, and is not qualified under
Section 401(a) of the Code.

        J.      FEDERAL INCOME TAX INFORMATION.

                The tax consequences arising in connection with options are
complex and subject to change. The following summary is only a general guide to
the current United States federal income tax consequences of options granted
under the Plan and does not describe all such possible tax consequences. In
addition, an optionee's particular situation may be such that some variation of
the general rules is applicable. For example, the following summary does not
describe the tax consequences of certain transactions, such as if shares of
common stock of the Company are used to exercise an option, if shares acquired
by exercise of an option are sold to certain related parties, or if the optionee
acquires substantially identical shares within the 30-day period before or after
a sale of shares acquired upon exercise of an option. OPTIONEES SHOULD CONSULT
THEIR OWN TAX ADVISORS PRIOR TO THE EXERCISE OF ANY OPTION AND PRIOR TO THE
DISPOSITION OF ANY SHARES ACQUIRED UNDER THE PLAN.

                (1)     Tax Consequences to Optionees. An optionee does not
realize taxable income when an option is granted. Upon the exercise of an
option, the optionee recognizes ordinary income on the "determination date"
(defined below) equal to the excess of the fair market value of the shares
acquired on the determination date over the price paid to acquire such shares.
Such income generally is subject to withholding of taxes. In general, upon the
disposition of the shares, any gain or loss, based on the difference between the
amount realized and the fair market value of the shares on the determination
date, will be capital gain or loss and taxed at a rate determined by the length
of time the shares were held:

                20% (long-term) if held for more than 12 months.
                39.6% (short-term) if held for not more than 12 months.

                (2)     Determination Date. Generally, the "determination date"
is the date on which the shares are acquired. The determination date for
unvested shares is the date on which the shares vest. If the optionee is an
insider and the grant of the option under the Plan is not exempt from the
application of Section 16(b) and shares are acquired by exercising the option
within six months of its grant date, the determination date is the later of the
date the shares vest or the date a sale of the shares by the insider is no
longer subject to suit under Section 16(b). If the determination date is after
the date on which the shares are acquired, the optionee may elect, under Section
83(b) of the Code, to have the exercise date be the determination date by filing
an election with the Internal Revenue Service not later than 30 days after the
date the shares are acquired.

                (3)     Tax Consequences to the Company. The Company is
generally entitled to a deduction equal to the amount of ordinary income
recognized by the optionee as a result of the exercise of an option, except to
the extent such deduction is limited by applicable provisions of the Code or the
regulations thereunder


   8
                (4)     Other Taxes. The above discussion is only a summary of
certain aspects of the highly complex United States federal income tax rules
applicable to options and does not deal with other taxes which may affect an
optionee, such as state and local income taxes, estate, gift and inheritance
taxes and taxes of countries other than the United States of America. Each
optionee should obtain and must rely on the advice of his or her own tax advisor
with respect to such matters.

        K.      RESTRICTIONS ON RESALE.

                (1)     Rule 144. Optionees with the power to manage and direct
the policies of the Company, relatives of such optionees, and trusts, estates,
corporations, or other organizations controlled by the foregoing persons may be
deemed to be "affiliates" of the Company. Affiliates generally are obligated to
resell shares in compliance with Rule 144 promulgated by the Securities and
Exchange Commission under the Securities Act of 1933, as amended, which requires
sales to be effected in "broker's transactions," as defined in such Rule, and
limits the number of shares which may be sold in any three-month period to no
more than the greater of 1% of the outstanding shares of the common stock of the
Company or the average weekly reported volume of trading in shares of the common
stock of the Company during the four calendar weeks preceding the filing of the
required notice of the proposed sale. However, since the shares have been
registered under the Securities Act of 1933, as amended, affiliates reselling
shares in compliance with Rule 144 are not subject to the holding period
requirement of Rule 144.

                (2)     Section 16(b). Section 16(b) permits the recovery by the
Company of any profit realized by an insider from each purchase and subsequent
sale, or sale and subsequent purchase, of shares of common stock of the Company
within any period of less than six months. If Rule 16b-3 is not complied with,
any sale by the insider of shares of the common stock of the Company within a
period of less than six months either before or after the date of grant of an
option under the Plan may subject the insider to recovery by the Company of any
"short-swing" profits realized. Optionees should consult their own legal
advisors prior to the disposition of any shares of the common stock of the
Company in order to ascertain the precise application of Section 16 of the
Exchange Act to their particular situation.

                (3)     Rule 10b-5. All optionees are subject to Rule 10b-5
under the Exchange Act, which prohibits any person from engaging in fraudulent
practices in connection with the purchase or sale of securities. This rule
generally prohibits optionees from buying or selling the Company's securities
using material information about the Company which has not yet been released to
the public. Before buying or selling any stock of the Company and, in
particular, before selling stock of the Company acquired under the Plan,
optionees should consult the Company regarding the applicability of any Company
"trading window policies" prohibiting trading in the Company's stock by certain
persons during specified periods of the year when material inside information is
likely to be held by such persons prior to its release to the public.

        L.      STOCK PURCHASE RIGHTS.


   9
                On September 18, 1996 the Board declared a dividend distribution
of one preferred stock purchase right (each a "Right" and collectively the
"Rights") on each share of the common stock of the Company outstanding on
October 2, 1996. Until the occurrence of certain events, each share of common
stock of the Company issued pursuant to the Plan will include a Right. The
Rights entitle the stockholders to purchase stock in the Company in the event of
certain hostile efforts to acquire control of the Company. The Rights will
expire at the close of business on September 17, 2006, unless earlier redeemed
or exchanged by the Company. The terms of the Rights, which are set forth in the
Rights Agreement dated September 18, 1996 by and between the Company and First
National Bank of Boston, are described in the Company's registration statement
on Form 8-A filed on October 10, 1996, which is incorporated by reference in the
Company's registration statement for the securities offered under this Plan.
