                         ANNUAL MEETING OF SHAREHOLDERS
                                  JUNE 4, 1999
 
                  APPROXIMATE DATE OF MAILING: APRIL 26, 1999
 
     This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of Xicor, Inc. (the "Company" or "Xicor") of proxies for
use at the Annual Meeting of Shareholders of Xicor (the "Annual Meeting") to be
held on Friday, June 4, 1999 at 1:00 p.m. local time or at any adjournment or
postponement thereof.
 
                                 VOTING RIGHTS
 
     Shareholders of record of Xicor as of the close of business on April 9,
1999 have the right to receive notice of and to vote at the Annual Meeting. On
April 9, 1999, Xicor had issued and outstanding 20,209,121 shares of Common
Stock, the only class of voting securities outstanding. Each share of Common
Stock is entitled to one vote.
 
     Each shareholder voting at the election of directors may cumulate such
shareholder's votes and give one candidate a number of votes equal to the number
of directors to be elected multiplied by the number of votes to which the
shareholder's shares are entitled, or distribute such votes, on the same
principle, among as many candidates as the shareholder thinks fit, provided that
votes cannot be cast for more candidates than the number of directors to be
elected. However, no shareholder will be entitled to cumulate votes unless, in
conformance with the California Corporations Code, a shareholder has given
notice at the Annual Meeting, prior to the voting, of the shareholder's
intention to cumulate such shareholder's votes. If any one shareholder has given
such notice, all shareholders may cumulate their votes for candidates in
nomination.
 
                                    PROXIES
 
     Properly executed and unrevoked proxies received by Xicor will be voted at
the Annual Meeting in accordance with the instructions thereon. Where no
instructions are specified, the proxies will be voted in favor of all proposals
set forth in the Notice of Meeting.
 
     Any person giving a proxy in the form accompanying this Proxy Statement has
the power to revoke it at any time before its exercise by filing with the
Secretary of Xicor (i) a signed written statement revoking the proxy or (ii) an
executed proxy bearing a date later than that of the proxy being revoked. A
proxy may also be revoked by attendance at the Annual Meeting and election to
vote in person. Attendance at the Annual Meeting will not by itself constitute
the revocation of a proxy.
 
                     QUORUM: ABSTENTIONS; BROKER NON-VOTES
 
     The required quorum for the transaction of business at the Annual Meeting
is a majority of the shares of Common Stock issued and outstanding on the Record
Date. Shares that are voted "FOR", "AGAINST" or "WITHHELD FROM" a matter are
treated as being present at the meeting for purposes of establishing a
 
                                        1
<PAGE>   4
 
quorum and are also treated as shares "represented and voting" at the Annual
Meeting (the "Votes Cast") with respect to such matter.
 
     While there is no definitive statutory or case law authority in California
as to the proper treatment of abstentions, the Company believes that abstentions
should be counted for purposes of determining both (i) the presence or absence
of a quorum for the transaction of business and (ii) the total number of Votes
Cast with respect to a proposal. In the absence of controlling precedent to the
contrary, the Company intends to treat abstentions in this manner. Accordingly,
abstentions will have the same effect as a vote against a proposal.
 
     Broker non-votes will be counted for purposes of determining the presence
or absence of a quorum for the transaction of business, but will not be counted
for purposes of determining the number of Votes Cast with respect to a proposal.
 
         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
 
     The following table sets forth as of April 9, 1999 the name, address and
number of shares of each person or entity known to Xicor to own beneficially
more than five percent (5%) of its Common Stock and the number of shares
beneficially owned by each director, by each of the executive officers named in
the Summary Compensation Table and by all executive officers and directors as a
group, together with their respective percentage ownership of outstanding
shares.

                      APPROVAL OF AMENDMENT TO THE BYLAWS
 
     The Company's Bylaws currently provide that the authorized number of
directors shall be no less than three nor more than five. The Board of Directors
believes it is advisable to increase the number of directors in order to give
the Company the flexibility in the future to add directors from outside the
Company with experience relevant to the Company's long-term strategic goals.
 
     Accordingly, the Board of Directors is proposing an amendment to the Bylaws
for approval by shareholders holding a majority of the outstanding shares of
Common Stock of the Company that provides that the Board of Directors will
consist of not less than four nor more than seven directors, with the exact
number to be fixed by approval of the Board of Directors or the shareholders.
 
     The shareholders are asked to approve the amendment and initially set the
number of directors at five. The amendment would replace Article I, Section 2 of
the Bylaws in its entirety with the following:
 
     "SECTION 2. NUMBER AND QUALIFICATION.
 
          The authorized number of directors of the corporation shall be no less
     than four (4) nor more than seven (7), with the exact number of directors
     to be fixed within the limits specified by approval of the Board of
     Directors or Shareholders.

    APPROVAL AND RATIFICATION OF AMENDMENTS TO THE COMPANY'S 1990 INCENTIVE
                      AND NON-INCENTIVE STOCK OPTION PLAN
 
     The Company's 1990 Incentive and Non-Incentive Stock Option Plan (the
"Plan") was originally adopted by the Board of Directors (the "Board") on
October 21, 1989 and approved by the shareholders on August 9, 1990.
 
     On March 15, 1999, the Board amended the Plan to: (i) increase the
aggregate number of shares of Common Stock authorized for issuance under the
Plan by 250,000 shares (bringing the total number of shares of Common Stock
available at March 15, 1999 for future awards under the Plan to 685,000 shares,
and raising the number of shares reserved for issuance under the Plan since its
inception to 3,450,000); (ii) remove language from the Plan that contemplated
the issuance of Stock Purchase Rights; (iii) allow members of the Board who are
also employees of the Company to receive options under the Plan; and (iv) extend
the expiration date of the Plan to March 15, 2004. The shareholders are being
asked to approve the foregoing amendments to the Plan and the increase in the
number of shares thereunder.
 
       SUMMARY OF THE 1990 INCENTIVE AND NON-INCENTIVE STOCK OPTION PLAN
 
     General. The purpose of the Plan is to attract and retain the best
available personnel for positions of substantial responsibility with the
Company, to provide additional incentive to the employees and consultants of the
Company and to promote the success of the Company's business. The Plan provides
for the grant of "incentive stock options," as defined in Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), or non-statutory stock
options.
 
     Administration. The Plan may generally be administered by the Board or
Committees appointed by the Board (as applicable, the "Administrator").
 
     Eligibility; Limitations. Non-statutory stock options may be granted under
the Plan to employees and consultants of the Company and any parent or
subsidiary of the Company. Incentive stock options may be granted only to
employees. The Administrator, in its discretion, selects the employees and
consultants to whom options may be granted, the time or times at which such
options shall be granted, and the number of shares subject to each such grant.
 
     Section 162(m) of the Code places limits on the deductibility for federal
income tax purposes of compensation paid to certain executive officers of the
Company. In order to preserve the Company's ability to deduct the compensation
income associated with options granted to such persons, the Plan provides that
no employee or consultant may be granted, in any fiscal year of the Company,
options to purchase more than 200,000 shares of Common Stock.
 
     Terms and Conditions of Options. Each option is evidenced by a stock option
agreement between the Company and the optionee, and is subject to the following
additional terms and conditions:
 
     (a) Exercise Price. The Administrator determines the exercise price of
options at the time the options are granted. The exercise price of an incentive
stock option may not be less than 100% of the fair market value of the Common
Stock on the date such option is granted; provided, however, that the exercise
price of an incentive stock option granted to a 10% stockholder may not be less
than 110% of the fair market value of the Common Stock on the date such option
is granted. The fair market value of the Common Stock is generally determined
with reference to the closing sale price for the Common Stock (or the closing
bid if no sales were reported) on the date the option is granted.
 
     (b) Exercise of Option; Form of Consideration. The Administrator determines
when options become exercisable, and may in its discretion, accelerate the
vesting of any outstanding option. Stock options granted under the Plan
generally vest and become exercisable over four years. The means of payment for
shares issued upon exercise of an option is specified in each option agreement.
The Plan permits payment to be made by cash, check, promissory note, other
shares of Common Stock of the Company (with some restrictions),
 
                                        7
<PAGE>   10
 
cashless exercises, a reduction in the amount of any Company liability to the
optionee, any other form of consideration permitted by applicable law, or any
combination thereof.
 
     (c) Term of Option. The term of an incentive stock option may be no more
than ten (10) years from the date of grant; provided that in the case of an
incentive stock option granted to a 10% stockholder, the term of the option may
be no more than five (5) years from the date of grant. No option may be
exercised after the expiration of its term.
 
     (d) Termination of Employment. If an optionee's employment or consulting
relationship terminates for any reason (other than death, disability or a
reduction in force, as defined in the Plan), then all options held by the
optionee under the Plan expire on the earlier of (i) the date set forth in his
or her notice of grant (normally three months past termination) or (ii) the
expiration date of such option. If, on the date of termination, the optionee is
not vested as to his or her entire option, the shares covered by the unvested
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 by the
Administrator, the option shall terminate, and the shares covered by such option
shall revert to the Plan.
 
     (e) Death, Disability or Reduction in Force. If an optionee's employment or
consulting relationship terminates as a result of death, disability or a
reduction in force, then all options held by such optionee under the Plan expire
on the earlier of (i) 12 months from the date of such termination or (ii) the
expiration date of such option. The optionee (or the optionee's estate or the
person who acquires the right to exercise the option by bequest or inheritance),
may exercise all or part of the option at any time before such expiration to the
extent that the option was exercisable at the time of such termination.
 
     (g) Nontransferability of Options. Options granted under the Plan are
generally not transferable other than by will or the laws of descent and
distribution, and may be exercised during the optionee's lifetime only by the
optionee.
 
     (h) Other Provisions. The stock option agreement may contain other terms,
provisions and conditions not inconsistent with the Plan as may be determined by
the Administrator.
 
     Adjustments Upon Changes in Capitalization. In the event that the stock of
the Company changes by reason of any stock split, reverse stock split, stock
dividend, combination, reclassification or other similar change in the capital
structure of the Company effected without the receipt of consideration,
appropriate adjustments shall be made in the number and class of shares of stock
subject to the Plan, the number and class of shares of stock subject to any
option outstanding under the Plan, and the exercise price of any such
outstanding option.
 
     In the event of a liquidation or dissolution, any unexercised options will
terminate. The Administrator may, in its discretion provide that each optionee
shall have the right to exercise all of the optionee's options, including those
not otherwise exercisable, until the date ten (10) days prior to the
consummation of the liquidation or dissolution.
 
     In connection with any merger, consolidation, acquisition of assets or like
occurrence involving the Company, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation. If the successor
corporation refuses to assume the options or to substitute substantially
equivalent options, the optionee shall have the right to exercise the option as
to all the optioned stock, including shares not otherwise exercisable. In such
event, the Administrator shall notify the optionee that the option is fully
exercisable for fifteen (15) days from the date of such notice and that the
option terminates upon expiration of such period.
 
     Amendment and Termination of the Plan. The Board may amend, alter, suspend
or terminate the Plan, or any part thereof, at any time and for any reason. No
such action by the Board or shareholders may alter or impair any option
previously granted under the Plan without the written consent of the optionee.
Unless terminated earlier, the Plan shall terminate March 15, 2004.
 
     Outstanding Options. Including the 250,000 share increase approved by the
Board on March 15, 1999, the total number of shares reserved for issuance since
the Plan's inception is 3,450,000. As of April 9, 1999, of
                                        8
<PAGE>   11
 
this amount 654,550 shares have been issued upon exercise of options, option for
2,095,925 shares have been granted and are outstanding and options for 699,525
shares are available for grant.
 
                        FEDERAL INCOME TAX CONSEQUENCES
 
     Incentive Stock Options. An optionee who is granted an incentive stock
option does not recognize taxable income at the time the option is granted or
upon its exercise, although the exercise may subject the optionee to alternative
minimum tax. Upon a disposition of the shares more than two years after grant of
the option and one year after exercise of the option, any gain or loss is
treated as long-term capital gain or loss. If these holding periods are not
satisfied, the optionee recognizes ordinary income at the time of disposition
equal to the difference between the exercise price and the lower of (i) the fair
market value of the shares at the date of the option exercise or (ii) the sale
price of the shares. Any gain or loss recognized on such a premature disposition
of the shares in excess of the amount treated as ordinary income is treated as
long-term or short-term capital gain or loss, depending on the holding period. A
different rule for measuring ordinary income upon such a premature disposition
may apply if the optionee is also an officer or 10% shareholder of the Company.
The Company is entitled to a deduction in the same amount as the ordinary income
recognized by the optionee.
 
     Nonstatutory Stock Options. An optionee does not recognize any taxable
income at the time he or she is granted a nonstatutory stock option. Upon
exercise, the optionee recognizes taxable income generally measured by the
excess of the then fair market value of the shares over the exercise price. Any
taxable income recognized in connection with an option exercise by an employee
of the Company is subject to tax withholding by the Company. The Company is
entitled to a deduction in the same amount as the ordinary income recognized by
the optionee. Upon a disposition of such shares by the optionee, any difference
between the sale price and the optionee's exercise price, to the extent not
recognized as taxable income as provided above, is treated as long-term or
short-term capital gain or loss, depending on the holding period.
 
     THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME TAXATION
UPON OPTIONEES AND THE COMPANY WITH RESPECT TO THE GRANT AND EXERCISE OF OPTIONS
UNDER THE PLAN. IT DOES NOT PURPORT TO BE COMPLETE, AND DOES NOT DISCUSS THE TAX
CONSEQUENCES OF THE EMPLOYEE'S OR CONSULTANT'S DEATH OR THE PROVISIONS OF THE
INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH THE
EMPLOYEE OR CONSULTANT MAY RESIDE.
 
                                 REQUIRED VOTE
 
     The affirmative vote of the holders of a majority of the shares represented
and voting at the Annual Meeting is required to approve the Ratification and
Amendments to the 1990 Incentive and Non-Incentive Stock Option Plan.
 
 THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE APPROVAL OF
    THE AMENDMENTS TO THE 1990 INCENTIVE AND NON-INCENTIVE STOCK OPTION PLAN

                                 PROPOSAL NO. 4
 
                     DESIGNATION OF INDEPENDENT ACCOUNTANTS
 
     The Board of Directors has approved the retention of PricewaterhouseCoopers
LLP as independent accountants for Xicor until revoked by further action.
PricewaterhouseCoopers LLP has been Xicor's independent accountants since 1979.
 
     The shareholders are asked to ratify the designation of
PricewaterhouseCoopers LLP as independent accountants for Xicor for the fiscal
year ending December 31, 1999. A representative of PricewaterhouseCoopers LLP is
expected to be present at the Annual Meeting to make a statement if he desires
to do so, and such representative is expected to be available to respond to
appropriate questions.
 
     Submission of this proposal to the shareholders is not required by Xicor's
Bylaws or otherwise. The management of Xicor has elected to do so as a matter of
good corporate practice. Should the shareholders fail to ratify the designation
of PricewaterhouseCoopers LLP as independent accountants, retention of the firm
for the fiscal year ending December 31, 1999 will be reconsidered by the Board
of Directors.
 
     Unless marked to the contrary, proxies received will be voted "FOR"
ratification of the designation of PricewaterhouseCoopers LLP as independent
accountants for Xicor's fiscal year ending December 31, 1999.
 
       THE BOARD OF DIRECTORS RECOMMENDS VOTING "FOR" SUCH RATIFICATION.
 
                                 OTHER MATTERS
 
     Management knows of no business that will be presented for consideration at
the Annual Meeting other than as stated in the Notice of Meeting. If, however,
other matters are properly brought before the Annual Meeting, it is the
intention of the persons named in the accompanying form of proxy to vote the
shares represented thereby on such matters in accordance with their best
judgment.
 
     The expense of solicitation of proxies will be borne by Xicor. In addition
to solicitation of proxies by mail, certain officers, directors and Xicor
employees who will receive no additional compensation for their services may
solicit proxies by telephone, facsimile or personal interview. Xicor has
retained the services of Kissel-Blake to aid in the solicitation of proxies from
brokers, bank nominees and other institutional owners, if necessary. Xicor will
pay Kissel-Blake a fee which is not expected to exceed $5,500 for its services
and will reimburse Kissel-Blake for out-of-pocket expenses estimated to be
$8,000. Xicor is required to request brokers and nominees who hold stock in
their name to furnish this proxy material to beneficial owners of the stock and
will reimburse such brokers and nominees for their reasonable out-of-pocket
expenses in so doing.
 
                              CERTAIN TRANSACTIONS
 
     Daniel L. Lewis joined Xicor in May 1998 as Vice President, Worldwide
Sales. In connection with his employment, Xicor made a non-interest bearing loan
to him in the amount of $320,000 payable in full on October 22, 1999. The loan
is secured by a third deed of trust on real property.
 
            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors and executive officers, and persons who own more than
10% of a registered class of the Company's equity securities, to file reports of
ownership and reports of changes in ownership with the Securities and Exchange
Commission (SEC). Such persons are required by SEC regulation to furnish the
Company with copies of all Section 16(a) forms they file.
 
     Based solely on its review of the copies of such forms for 1998, Xicor
believes that all applicable filing requirements have been complied with, except
that a Form 4 involving a stock option exercise for 1,250 shares was filed late
by Mr. Timothy Kanemoto, a Vice President.

                      REPORT OF THE COMPENSATION COMMITTEE
 
     Xicor applies a consistent philosophy to compensation for all employees,
including senior management, based on the premise that the achievements of Xicor
result from the coordinated efforts of all individuals working toward common
objectives. Xicor strives to achieve those objectives through teamwork that is
focused on meeting the expectations of customers and shareholders.
 
COMPENSATION PHILOSOPHY
 
     The goals of the compensation program are to align compensation with
business objectives and performance, and to enable Xicor to attract, retain and
reward executive officers who contribute to the long-term success of Xicor.
Xicor's compensation program for its Chief Executive Officer and other executive
officers is based on the same four principles applicable to compensation
decisions for all Xicor employees:
 
     - Xicor pays competitively.
 
       Xicor is committed to providing a pay program that helps attract and
       retain high caliber executives. To ensure that pay is competitive, Xicor
       compares its pay practices for its Chief Executive Officer and other
       executives with those of other electronics companies, with particular
       emphasis on similar size semiconductor companies, and sets its pay
       parameters based on this review.
 
     - Xicor compensates for relative sustained performance.
 
       The Chief Executive Officer and other executive officers are rewarded
       based upon corporate performance and individual performance. Corporate
       performance is evaluated by reviewing the extent to which business plan
       goals are met, including such factors as operating profit, performance
       relative to competitors and timely new product introductions. Individual
       performance is evaluated by reviewing progress against set objectives and
       business goals.
 
     - Xicor strives for fairness in the administration of compensation.
 
       Xicor strives to achieve a balance of the compensation paid to a
       particular executive and the compensation paid to other executives both
       inside Xicor and at comparable companies.
 
     - Xicor believes that executives should understand the performance
       evaluation and compensation administration process.
 
       The process of assessing performance is as follows: At the beginning of
       the performance cycle, the evaluating executive (or in the case of the
       Chief Executive Officer and of the President and Chief Operating Officer,
       the Board of Directors) sets objectives and key goals. The executive is
       given ongoing feedback on performance. At the end of the performance
       cycle, the accomplishment of objectives and key goals is evaluated, the
       results compared to the results of peers within the Company and the
       comparative results are communicated to the executive. The comparative
       result affects decisions on salary, bonuses and stock options.
 
COMPENSATION VEHICLES
 
     Xicor uses a compensation program that consists of the following cash-and
equity-based vehicles:
 
CASH-BASED COMPENSATION
 
  Salary and Bonus
 
     Xicor sets base salary and determines bonus amounts for the Chief Executive
Officer and other executives by reviewing corporate and individual performance
and the aggregate of base salary and annual bonus for comparable positions in
the electronics industry, with emphasis on comparable size semiconductor
companies. The base salary of the Chief Executive Officer was not changed during
1998. The base salary of the President and Chief Operating Officer was increased
upon his promotion to such position in January 1998.
 
                                       11
<PAGE>   14
 
  Cash Profit-Sharing
 
     Xicor has an employee incentive cash bonus profit-sharing program (the
"Program"). Under the Program, twice a year (two profit sharing periods) 5% to
15% of Xicor's consolidated operating income, excluding certain non-product
revenues, is distributed to all employees including the Chief Executive Officer
and other executive officers as Xicor believes that all employees share the
responsibility of achieving profits. The exact percentage to be distributed is
determined by a Committee of the Board of Directors; however, in no event may
the distribution result in a net loss after taxes to Xicor for any profit
sharing period. The same profit-sharing percentage applies to each employee,
with the payment determined by applying this percentage to the individuals base
salary. No profit sharing bonuses were paid relating to 1998.
 
EQUITY-BASED COMPENSATION
 
  Stock Option Program
 
     Stock options are granted to provide additional incentives to key employees
to work to maximize shareholder value. The option program also utilizes vesting
periods to encourage key employees, including executive officers, to continue in
the employ of Xicor. Xicor has a 1990 Incentive and Non-Incentive Stock Option
Plan and a 1998 Non-Statutory Stock Option Plan. Neither independent Directors
nor any executives who are also Board members may be granted options under the
1990 Incentive and Non-Incentive Stock Option Plan. Proposal No. 3, if approved,
will make executive officers who are also Directors eligible to receive stock
options under this plan. Officers and Directors are not eligible to receive
options under the 1998 Non-Statutory Stock Option Plan. On February 2, 1998
Xicor repriced all underwater outstanding options under the 1990 Incentive and
Non-Incentive Stock Option Plan for its employees and officers in order to
retain such employees and officers, including the newly appointed President and
Chief Operating Officer, due to the highly competitive employment environment in
Silicon Valley. None of the options repriced for executive officers were
exercisable for a six (6) month period from the repricing date. All options were
repriced to $2.75 per share, the fair market value on the date of repricing.
Xicor's Chief Executive Officer, who is also the Chairman of the Board, and
Xicor's President and Chief Operating Officer, who was elected a Director in
1998, were granted options in 1998 under the 1995 Director Option Plan based on
a formula included in the Plan.

(1) Options become exercisable at the rate of 25% of the underlying shares per
    year, generally commencing one year from the date of grant. Repriced options
    retain the exercise and expiration dates of the original option except that
    no options were exercisable for a six (6) month period from the date of
    repricing.
 
(2) The potential realizable value is based on the term of the option (10 years)
    at the date of grant. It is calculated by assuming that the stock price on
    the date of grant (which is equal to the exercise price) appreciates at the
    indicated annual rate, compounded annually for the entire term, and that the
    option is exercised and sold on the last day of the option term for the
    appreciated stock price. These values are calculated based on requirements
    promulgated by the Securities and Exchange Commission and do not reflect the
    Company's estimate of future stock price appreciation. Actual gains, if any,
    are dependent on the future performance of the Company's Common Stock.
 
(3) Represents options repriced in 1998.

its Parent, any Subsidiary, or any successor, or (iii) a Service Provider whose

such leave may exceed ninety days, unless reemployment upon expiration of such
leave is guaranteed by statute or contract. If reemployment upon expiration of a
leave of absence approved by the Company is not so guaranteed, on the 181st day
of such leave any Incentive Stock Option held by the Optionee shall cease to be

     to the day of determination, as reported in The Wall Street Journal or such

                                       -2-
<PAGE>   21
 
     If an Option expires or becomes unexercisable without having been exercised
in full, or is surrendered pursuant to an Option Exchange Program, the
unpurchased Shares that were subject thereto shall become available for future
grant or sale under the Plan (unless the Plan has terminated); provided,
however, that Shares that have actually been issued under the Plan, upon
exercise of an Option, shall not be returned to the Plan and shall not become
available for future distribution under the Plan.
 
     4. Administration of the Plan.
 
     (a) Procedure.
 
           (i) Multiple Administrative Bodies. The Plan may be administered by
     different bodies with respect to different groups of Service Providers.
 
           (ii) Section 162(m). To the extent that the Administrator determines
     it to be desirable to qualify Options granted hereunder as
     "performance-based compensation" within the meaning of Section 162(m) of
     the Code, the Plan shall be administered by a Committee of two or more
     "outside directors" within the meaning of Section 162(m) of the Code.
 
           (iii) Rule 16b-3. To the extent desirable to qualify transactions
     hereunder as exempt under Rule 16b-3, the transactions contemplated
     hereunder shall be structured to satisfy the requirements for exemption
     under Rule 16b-3.
 
           (iv) Other Administration. Other than as provided above, the Plan
     shall be administered by (A) the Board or (B) Committees, which committees
     shall be constituted to satisfy Applicable Laws.
 
     (b) Powers of the Administrator. Subject to the provisions of the Plan, and
in the case of Committees, subject to the specific duties delegated by the Board
to such Committees, the Administrator shall have the authority, in its
discretion:
 
           (i) to determine the Fair Market Value;
 
           (ii) to select the Service Providers to whom Options may be granted
     hereunder;
 
           (iii) to determine the number of shares of Common Stock to be covered
     by each Option granted hereunder;
 
           (iv) to approve forms of agreement for use under the Plan;
 
           (v) to determine the terms and conditions, not inconsistent with the
     terms of the Plan, of any Option granted hereunder. Such terms and
     conditions include, but are not limited to, the exercise price, the time or
     times when Options may be exercised (which may be based on performance
     criteria), any vesting acceleration or waiver of forfeiture restrictions,
     and any restriction or limitation regarding any Option or the shares of
     Common Stock relating thereto, based in each case on such factors as the
     Administrator, in its sole discretion, shall determine;
 
           (vi) to reduce the exercise price of any Option to the then current
     Fair Market Value if the Fair Market Value of the Common Stock covered by
     such Option shall have declined since the date the Option was granted;
 
          (vii) to institute an Option Exchange Program;
 
          (viii) to construe and interpret the terms of the Plan and awards
     granted pursuant to the Plan;
 
           (ix) to prescribe, amend and rescind rules and regulations relating
     to the Plan, including rules and regulations relating to sub-plans
     established for the purpose of qualifying for preferred tax treatment under
     foreign tax laws;
 
           (x) to modify or amend each Option (subject to Section 14(c) of the
     Plan), including the discretionary authority to extend the post-termination
     exercisability period of Options longer than is otherwise provided for in
     the Plan;
 
                                       -3-
<PAGE>   22
 
           (xi) to allow Optionees to satisfy withholding tax obligations by
     electing to have the Company withhold from the Shares to be issued upon
     exercise of an Option that number of Shares having a Fair Market Value
     equal to the amount required to be withheld. The Fair Market Value of the
     Shares to be withheld shall be determined as of the date that the amount of
     tax to be withheld is to be determined. All elections by an Optionee to
     have Shares withheld for this purpose shall be made in such form and under
     such conditions as the Administrator may deem necessary or advisable;
 
          (xii) to authorize any person to execute on behalf of the Company any
     instrument required to effect the grant of an Option previously granted by
     the Administrator;
 
          (xiii) to make all other determinations deemed necessary or advisable
     for administering the Plan.
 
     (c) Effect of Administrator's Decision. The Administrator's decisions,
determinations and interpretations shall be final and binding on all Optionees
and any other holders of Options.
 
     5. Eligibility. Nonstatutory Stock Options may be granted to Employees and
Consultants. Incentive Stock Options may be granted only to Employees.
 
     6. Limitations.
 
     (a) Each Option shall be designated in the Option Agreement as either an
Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding
such designation, to the extent that the aggregate Fair Market Value of the
Shares with respect to which Incentive Stock Options are exercisable for the
first time by the Optionee during any calendar year (under all plans of the
Company and any Parent or Subsidiary) exceeds $100,000, such excess Options
shall be treated as Nonstatutory Stock Options. For purposes of this Section
6(a), Incentive Stock Options shall be taken into account in the order in which
they were granted and the Fair Market Value of the Shares shall be determined as
of the time the Option with respect to such Shares is granted.
 
     (b) Neither the Plan nor any Option shall confer upon an Optionee any right
with respect to continuing the Optionee's relationship as a Service Provider
with the Company, nor shall they interfere in any way with the Optionee's right
or the Company's right to terminate such relationship at any time, with or
without cause.
 
     (c) The following limitations shall apply to grants of Options:
 
           (i) No Service Provider shall be granted, in any fiscal year of the
     Company, Options to purchase more than 200,000 Shares.
 
           (ii) The foregoing limitation shall be adjusted proportionately in
     connection with any change in the Company's capitalization as described in
     Section 12.
 
           (iii) If an Option is canceled in the same fiscal year of the Company
     in which it was granted (other than in connection with a transaction
     described in Section 12), the canceled Option will be counted against the
     limit set forth in subsection (i) above. For this purpose, if the exercise
     price of an Option is reduced, the transaction will be treated as a
     cancellation of the Option and the grant of a new Option.
 
     7. Term of Plan. Subject to Section 18 of the Plan, the Plan shall continue
in effect for a term of five (5) years from March 15, 1999 unless terminated
earlier under Section 14 of the Plan.
 
     8. Term of Option. The term of each Option shall be stated in the Option
Agreement. In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement. Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary, the term of the Incentive
Stock Option shall be five (5) years from the date of grant or such shorter term
as may be provided in the Option Agreement.

     9. Option Exercise Price and Consideration.
 
     (a) Exercise Price. The per share exercise price for the Shares to be
issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:
 
           (i) In the case of an Incentive Stock Option
 
             (A) granted to an Employee who, at the time the Incentive Stock
        Option is granted, owns stock representing more than ten percent (10%)
        of the voting power of all classes of stock of the Company or any Parent
        or Subsidiary, the per Share exercise price shall be no less than 110%
        of the Fair Market Value per Share on the date of grant.
 
           (B) granted to any Employee other than an Employee described in
        paragraph (A) immediately above, the per Share exercise price shall be
        no less than 100% of the Fair Market Value per Share on the date of
        grant.
 
           (ii) In the case of a Nonstatutory Stock Option, the per Share
     exercise price shall be determined by the Administrator. In the case of a
     Nonstatutory Stock Option intended to qualify as "performance-based
     compensation" within the meaning of Section 162(m) of the Code, the per
     Share exercise price shall be no less than 100% of the Fair Market Value
     per Share on the date of grant.
 
           (iii) Notwithstanding the foregoing, Options may be granted with a
     per Share exercise price of less than 100% of the Fair Market Value per
     Share on the date of grant pursuant to a merger or other corporate
     transaction.
 
     (b) Waiting Period and Exercise Dates. At the time an Option is granted,
the Administrator shall fix the period within which the Option may be exercised
and shall determine any conditions which must be satisfied before the Option may
be exercised.
 
     (c) Form of Consideration. The Administrator shall determine the acceptable
form of consideration for exercising an Option, including the method of payment.
In the case of an Incentive Stock Option, the Administrator shall determine the
acceptable form of consideration at the time of grant. Such consideration may
consist entirely of:
 
           (i) cash;
 
           (ii) check;
 
           (iii) promissory note;
 
           (iv) other Shares which (A) in the case of Shares acquired upon
     exercise of an option, have been owned by the Optionee for more than six
     months on the date of surrender, and (B) have a Fair Market Value on the
     date of surrender equal to the aggregate exercise price of the Shares as to
     which said Option shall be exercised;
 
           (v) consideration received by the Company under a cashless exercise
     program implemented by the Company in connection with the Plan;
 
           (vi) a reduction in the amount of any Company liability to the
     Optionee, including any liability attributable to the Optionee's
     participation in any Company-sponsored deferred compensation program or
     arrangement;
 
          (vii) any combination of the foregoing methods of payment; or
 
          (viii) such other consideration and method of payment for the issuance
     of Shares as permitted by Applicable Laws.
 
     10. Exercise of Option.
 
     (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the
 
                                       -5-
<PAGE>   24
 
Administrator and set forth in the Option Agreement. An Option may not be
exercised for a fraction of a Share.
 
     An Option shall be deemed exercised when the Company receives: (i) written
notice of exercise (in accordance with the Option Agreement) from the person
entitled to exercise the Option, and (ii) full payment for the Shares with
respect to which the Option is exercised. Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan. Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse. Until the Shares
are issued (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a shareholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option. The Company shall
issue (or cause to be issued) such Shares promptly after the Option is
exercised. No adjustment will be made for a dividend or other right for which
the record date is prior to the date the Shares are issued, except as provided
in Section 12 of the Plan.
 
     Exercising an Option in any manner shall decrease the number of Shares
thereafter available, both for purposes of the Plan and for sale under the
Option, by the number of Shares as to which the Option is exercised.
 
     (b) Termination of Relationship as a Service Provider. If an Optionee
ceases to be a Service Provider, other than upon the Optionee's death,
Disability or as a result of a RIF, the Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement to the extent
that the Option is vested on 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).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for three (3) months following the Optionee's termination.
If, on the date of termination, the Optionee is not vested as to his or her
entire Option, the Shares covered by the unvested 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 by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.
 
     (c) Disability of Optionee. If an Optionee ceases to be a Service Provider
as a result of the Optionee's Disability, the Optionee may exercise his or her
Option within such period of time as is specified in the Option Agreement to the
extent the Option is vested on 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). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested 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.
 
     (d) Death of Optionee. If an Optionee dies while a Service Provider, the
Option may be exercised within such period of time as is specified in the Option
Agreement (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who acquires the right to exercise the Option by bequest or inheritance, but
only to the extent that the Option is vested on the date of death. In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination. If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan. The Option may be exercised by the executor or administrator
of the Optionee's estate or, if none, by the person(s) entitled to exercise the
Option under the Optionee's will or the laws of descent or distribution. If the
Option is not so exercised within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.
 
     (e) Reduction in Force. If the Optionee ceases to be a Service Provider as
a result of a RIF, the Optionee may exercise his or her Option within such
period of time as is specified in the Option Agreement, to the extent the Option
is vested on 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). In the absence
of a specified time in the Option
                                       -6-
<PAGE>   25
 
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
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.
 
     (f) Buyout Provisions. The Administrator may at any time offer to buy out
for a payment in cash or Shares, an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.
 
     11. Non-Transferability of Options. Unless determined otherwise by the
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.
 
     12. Adjustments Upon Changes in Capitalization, Dissolution, Merger or
Asset Sale.
 
     (a) Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.
 
     (b) Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Administrator shall notify each Optionee as soon
as practicable prior to the effective date of such proposed transaction. The
Administrator in its discretion may provide for an Optionee to have the right to
exercise his or her Option until ten (10) days prior to such transaction as to
all of the Optioned Stock covered thereby, including Shares as to which the
Option would not otherwise be exercisable. In addition, the Administrator may
provide that any Company repurchase option applicable to any Shares purchased
upon exercise of an Option shall lapse as to all such Shares, provided the
proposed dissolution or liquidation takes place at the time and in the manner
contemplated. To the extent it has not been previously exercised, an Option will
terminate immediately prior to the consummation of such proposed action.
 
     (c) Merger or Asset Sale. In the event of a merger of the Company with or
into another corporation, or the sale of substantially all of the assets of the
Company, each outstanding Option may be assumed or an equivalent option may be
substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. The Administrator may, in lieu of such assumption or
substitution, provide for the Optionee to have the right to exercise the Option
as to all or a portion of the Optioned Stock, including Shares as to which it
would not otherwise be exercisable. If the Administrator makes an Option
exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets, the Administrator shall notify the Optionee in writing that the
Option shall be fully exercisable for a period of fifteen (15) days from the
date of such notice, and the Option shall terminate upon the expiration of such
period. For the purposes of this paragraph, the Option shall be considered
assumed if, following the merger or sale of assets, the option confers the right
to purchase or receive, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders
                                       -7-
<PAGE>   26
 
were offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.
 
     13. Date of Grant. The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.
 
     14. Amendment and Termination of the Plan.
 
     (a) Amendment and Termination. The Board may at any time amend, alter,
suspend or terminate the Plan.
 
     (b) Shareholder Approval. The Company shall obtain shareholder approval of
any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.
 
     (c) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.
 
     15. Conditions Upon Issuance of Shares.
 
     (a) Legal Compliance. Shares shall not be issued pursuant to the exercise
of an Option unless the exercise of such Option and the issuance and delivery of
such Shares shall comply with Applicable Laws and shall be further subject to
the approval of counsel for the Company with respect to such compliance.
 
     (b) Investment Representations. As a condition to the exercise of an
Option, the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.
 
     16. Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.
 
     17. Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.
 
     18. Shareholder Approval. Continuance of the Plan shall be subject to
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such shareholder approval shall be obtained
in the manner and to the degree required under Applicable Laws.

     This Option may be exercised, in whole or in part, in accordance with the
following schedule:
 
     25% of the Shares subject to the Option shall vest twelve months after the

II. AGREEMENT
 
     1. Grant of Option. The Plan Administrator of the Company hereby grants to
the Optionee named in the Notice of Grant attached as Part I of this Agreement
(the "Optionee") an option (the "Option") to purchase the number of Shares, as
set forth in the Notice of Grant, at the exercise price per share set forth in
the Notice of Grant (the "Exercise Price"), subject to the terms and conditions
of the Plan, which is incorporated herein by reference. Subject to Section 14(c)
of the Plan, in the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.
 
     2. Exercise of Option.
 
     (a) Right to Exercise. This Option is exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.
                                       -1-
<PAGE>   28
 
     (b) Method of Exercise. This Option is exercisable by delivery of an
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to Corporate Controller of the Company. The
Exercise Notice shall be accompanied by payment of the aggregate Exercise Price
as to all Exercised Shares. This Option shall be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.
 
     No Shares shall be issued pursuant to the exercise of this Option unless
such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.
 
     3. Method of Payment. Payment of the aggregate Exercise Price shall be by
any of the following, or a combination thereof, at the election of the Optionee:
 
          (a) cash; or
 
          (b) check; or
 
          (c) delivery of a properly executed exercise notice together with such
     other documentation as the Administrator and the broker, if applicable,
     shall require to effect an exercise of the Option and delivery to the
     Company of the sale or loan proceeds required to pay the exercise price.
 
     4. Non-Transferability of Option. This Option may not be transferred in any
manner other than by will or by the laws of descent or distribution and may be
exercised during the lifetime of Optionee only by the Optionee. The terms of the
Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.
 
     5. Term of Option. This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.
 
     6. Tax Consequences. Some of the federal tax consequences relating to this
Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
DISPOSING OF THE SHARES.
 
     (a) Exercising the Option. The Optionee may incur regular federal income
tax liability upon exercise of a Nonstatutory Stock Option (an "NSO"). The
Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess of the Fair Market Value of the
Exercised Shares on the date of exercise over their aggregate Exercise Price. If
the Optionee is an Employee or a former Employee, the Company will be required
to withhold from his or her compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may decline to honor the
exercise and decline to deliver Shares if such withholding amounts are not
delivered at the time of exercise.
 
     (b) Disposition of Shares. If the Optionee holds NSO Shares for at least
one year, any gain realized on disposition of the Shares (generally, the
difference between the Fair Market Value of the Shares at exercise and the
selling price) will be treated as long-term capital gain for federal income tax
purposes.
 
     7. Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a
 
                                       -2-
<PAGE>   29
 
writing signed by the Company and Optionee. This agreement is governed by the
internal substantive laws, but not the choice of law rules, of California.
 
     8. NO GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES AND AGREES THAT
THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY
CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE
ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER).
OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT
INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE OPTIONEE'S
RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.
 
     By your signature and the signature of the Company's representative below,
you and the Company agree that this Option is granted under and governed by the
terms and conditions of the Plan and this Option Agreement. Optionee has
reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
Agreement and fully understands all provisions of the Plan and Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions relating to the Plan
and Option Agreement. Optionee further agrees to notify the Company upon any
change in the residence address indicated below.

     This Option may be exercised, in whole or in part, in accordance with the
following schedule:
 
     25% of the Shares subject to the Option shall vest twelve months after the
Vesting Commencement Date, and 25% of the Shares subject to the Option shall

be exercised later than the Expiration Date as provided above.
 
II. AGREEMENT
 
     1. Grant of Option. The Plan Administrator of the Company hereby grants to
the Optionee named in the Notice of Grant attached as Part I of this Agreement
(the "Optionee") an option (the "Option") to purchase the number of Shares, as
set forth in the Notice of Grant, at the exercise price per share set forth in
the Notice of Grant (the "Exercise Price"), subject to the terms and conditions
of the Plan, which is incorporated herein by reference. Subject to Section 14(c)
of the Plan, in the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.
 
     This Option is intended to qualify as an Incentive Stock Option (an "ISO")
under Section 422 of the Code. However, to the extent that it exceeds the
$100,000 rule of Code Section 422(d) it shall be treated as a Nonstatutory Stock
Option ("NSO").
 
                                       -1-
<PAGE>   33
 
     2. Exercise of Option.
 
     (a) Right to Exercise. This Option is exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.
 
     (b) Method of Exercise. This Option is exercisable by delivery of an
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to Corporate Controller of the Company. The
Exercise Notice shall be accompanied by payment of the aggregate Exercise Price
as to all Exercised Shares. This Option shall be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.
 
     No Shares shall be issued pursuant to the exercise of this Option unless
such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.
 
     3. Method of Payment. Payment of the aggregate Exercise Price shall be by
any of the following, or a combination thereof, at the election of the Optionee:
 
          (a) cash; or
 
          (b) check; or
 
          (c) delivery of a properly executed exercise notice together with such
     other documentation as the Administrator and the broker, if applicable,
     shall require to effect an exercise of the Option and delivery to the
     Company of the sale or loan proceeds required to pay the exercise price.
 
     4. Non-Transferability of Option. This Option may not be transferred in any
manner other than by will or by the laws of descent or distribution and may be
exercised during the lifetime of Optionee only by the Optionee. The terms of the
Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.
 
     5. Term of Option. This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.
 
     6. Tax Consequences. Some of the federal tax consequences relating to this
Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
DISPOSING OF THE SHARES.
 
     (a) Exercising the Option. If this Option qualifies as an ISO, the Optionee
will have no regular federal income tax liability upon its exercise, although
the excess, if any, of the Fair Market Value of the Exercised Shares on the date
of exercise over their aggregate Exercise Price will be treated as an adjustment
to alternative minimum taxable income for federal tax purposes and may subject
the Optionee to alternative minimum tax in the year of exercise. In the event
that the Optionee ceases to be an Employee but remains a Service Provider, any
Incentive Stock Option of the Optionee that remains unexercised shall cease to
qualify as an Incentive Stock Option and will be treated for tax purposes as a
Nonstatutory Stock Option on the date three (3) months and one (1) day following
such change of status.
 
     (b) Disposition of Shares. If the Optionee does not dispose of ISO Shares
for at least one year after exercise and two years after the grant date, any
gain realized on disposition of the Shares will be treated as long-term capital
gain for federal income tax purposes. If the Optionee disposes of ISO Shares
within one year after exercise or two years after the grant date, any gain
realized on such disposition will be treated as compensation income (taxable at
ordinary income rates) to the extent of the excess, if any, of the lesser of
                                       -2-
<PAGE>   34
 
(A) the difference between the Fair Market Value of the Shares acquired on the
date of exercise and the aggregate Exercise Price, or (B) the difference between
the sale price of such Shares and the aggregate Exercise Price. Any additional
gain will be taxed as capital gain, short-term or long-term depending on the
period that the ISO Shares were held.
 
     (c) Notice of Disqualifying Disposition. If the Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to an ISO on or before the later
of (i) two years after the grant date, or (ii) one year after the exercise date,
the Optionee shall immediately notify the Company in writing of such
disposition. The Optionee agrees that he or she may be subject to income tax
withholding by the Company on the compensation income recognized from such early
disposition of ISO Shares by payment in cash or out of the current earnings paid
to the Optionee.
 
     7. Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by the internal substantive laws, but not
the choice of law rules, of California.
 
     8. NO GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES AND AGREES THAT
THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY
CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE
ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER).
OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT
INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE OPTIONEE'S
RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.
 
     By your signature and the signature of the Company's representative below,
you and the Company agree that this Option is granted under and governed by the
terms and conditions of the Plan and this Option Agreement. Optionee has
reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
Agreement and fully understands all provisions of the Plan and Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions relating to the Plan
and Option Agreement. Optionee further agrees to notify the Company upon any
