                           1995 EQUITY INCENTIVE PLAN


                           As Adopted August 24, 1995
      and amended on March 21, 1996, July 18, 1996, November 25, 1996, and
                                August 28, 1997


1. PURPOSE. The purpose of the Plan is to provide incentives to attract, retain
and motivate eligible persons whose present and potential contributions are
important to the success of the Company, its Parent, Subsidiaries and
Affiliates, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses. Capitalized terms not defined in the text are defined in Section 24.

2. SHARES SUBJECT TO THE PLAN.

        2.1 Number of Shares Available. Subject to Sections 2.2 and 18, the
total number of Shares reserved and available for grant and issuance pursuant to
the Plan shall be 3,807,000 Shares. Subject to Sections 2.2 and 18, Shares shall
again be available for grant and issuance in connection with future Awards under
the Plan that: (a) are subject to issuance upon exercise of an Option but cease
to be subject to such Option for any reason other than exercise of such Option,
(b) are subject to an Award granted hereunder but are forfeited or are
repurchased by the Company at the original issue price, or (c) are subject to an
Award that otherwise terminates without Shares being issued.

        2.2 Adjustment of Shares. In the event that the number of outstanding
Shares is changed by a stock dividend, recapitalization, stock split, reverse
stock split, subdivision, combination, reclassification or similar change in the
capital structure of the Company without consideration, then (a) the number of
Shares reserved for issuance under the Plan, (b) the Exercise Prices of and
number of Shares subject to outstanding Options, and (c) the number of Shares
subject to other outstanding Awards shall be proportionately adjusted, subject
to any required action by the Board or the shareholders of the Company and
compliance with applicable securities laws; provided, however, that fractions of
a Share shall not be issued but shall either be paid in cash at Fair Market
Value or shall be rounded up to the nearest Share, as determined by the
Committee.

3. ELIGIBILITY. ISOs (as defined in Section 5 below) may be granted only to
employees (including officers and directors who are also employees) of the
Company or of a Parent or Subsidiary of the Company. All other Awards may be
granted to employees, officers, directors, consultants, independent contractors
and advisers of the Company or any Parent, Subsidiary or Affiliate of the
Company; provided such consultants, contractors and advisers render bona fide
services not in connection with the offer and sale of securities in a
capital-raising transaction. A person may be granted more than one Award under
the Plan.

4. ADMINISTRATION.

        4.1 Committee Authority. The Plan shall be administered by the Committee
or the Board acting as the Committee. Subject to the general purposes, terms and
conditions of the Plan, and to the direction of the Board, the Committee shall
have full power to implement and carry out the Plan. The Committee shall have
the authority to:

        (a)     construe and interpret the Plan, any Award Agreement and any
                other agreement or document executed pursuant to the Plan;

        (e)     determine the number of Shares or other consideration subject to
                Awards;

        (f)     determine whether Awards will be granted singly, in combination,
                in tandem with, in replacement of, or as alternatives to, other
                Awards under the Plan or any other incentive or compensation
                plan of the Company or any Parent, Subsidiary or Affiliate of
                the Company;

        (g)     grant waivers of Plan or Award conditions;

        (h)     determine the vesting, exercisability and payment of Awards;

        (i)     correct any defect, supply any omission, or reconcile any
                inconsistency in the Plan, any Award or any Award Agreement;

        (j)     determine whether an Award has been earned; and

        (k)     make all other determinations necessary or advisable for the
                administration of the Plan.

        4.2 Committee Discretion. Any determination made by the Committee with
respect to any Award shall be made in its sole discretion at the time of grant
of the Award or, unless in contravention of any express term of the Plan or
Award, at any later time, and such determination shall be final and binding on
the Company and all persons having an interest in any Award under the Plan. The
Committee may delegate to one or more officers of the Company the authority to
grant an Award under the Plan to Participants who are not Insiders of the
Company.

        4.3 Exchange Act Requirements. If the Company is subject to the Exchange
Act, the Company will take appropriate steps to comply with the disinterested
director requirements of Section 16(b) of the Exchange Act, including but not
limited to, the appointment by the Board of a Committee consisting of not less
than two persons (who are members of the Board), each of whom is a Disinterested
Person.

5. OPTIONS. The Committee may grant Options to eligible persons and shall
determine whether such Options shall be Incentive Stock Options within the
meaning of the Code ("ISOs") or Nonqualified Stock Options ("NQSOs"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

        5.1 Form of Option Grant. Each Option granted under the Plan shall be
evidenced by an Award Agreement which shall expressly identify the Option as an
ISO or NQSO ("Stock Option Agreement"), and be in such form and contain such
provisions (which need not be the same for each Participant) as the Committee
shall from time to time approve, and which shall comply with and be subject to
the terms and conditions of the Plan.

        5.2 Date of Grant. The date of grant of an Option shall be the date on
which the Committee makes the determination to grant such Option, unless
otherwise specified by the Committee. The Stock Option Agreement and a copy of
the Plan will be delivered to the Participant within a reasonable time after the
granting of the Option.

        5.3 Exercise Period. Options shall be exercisable within the times or
upon the events determined by the Committee as set forth in the Stock Option
Agreement; provided, however, that no Option shall be exercisable after the
expiration of ten (10) years from the date the Option is granted, and provided
further that no Option granted to a person who directly or by attribution owns
more than ten percent (10%) of the total combined voting power of all classes of
stock of the Company or any Parent or Subsidiary of the Company ("Ten Percent
Shareholder") shall be exercisable after the expiration of five (5) years from
the date the Option is granted. The Committee also may provide for the exercise
of Options to become exercisable at one time or from time to time, periodically
or otherwise, in such number or percentage as the Committee determines.

        5.4 Exercise Price. The Exercise Price shall be determined by the
Committee when the Option is granted and may be not less than 85% of the Fair
Market Value of the Shares on the date of grant; provided that (i) the Exercise
Price of an ISO shall be not less than 100% of the Fair Market Value of the
Shares on the date of grant and (ii) the Exercise Price of any Option granted to
a Ten Percent Shareholder shall not be less than 110% of the Fair Market Value
of the Shares on the date of grant. Payment for the Shares purchased may be made
in accordance with Section 8 of the Plan.

        5.5 Method of Exercise. Options may be exercised only by delivery to the
Company of a written stock option exercise agreement (the "Exercise Agreement")
in a form approved by the Committee (which need not be the same for each
Participant), stating the number of Shares being purchased, the restrictions
imposed on the Shares, if any, and such representations and agreements regarding
Participant's investment intent and access to information, if any, as may be
required or desirable by the Company to comply with applicable securities laws,
together with payment in full of the Exercise Price for the number of Shares
being purchased.

        5.6 Termination. Notwithstanding the exercise periods set forth in the
Stock Option Agreement, exercise of an Option shall always be subject to the
following:

                                       
                                       3
<PAGE>   4

        (a)    If the Participant is Terminated for any reason except death or
               Disability, then Participant may exercise such Participant's
               Options only to the extent that such Options would have been
               exercisable upon the Termination Date no later than three (3)
               months after the Termination Date (or such shorter time period,
               but not less than thirty (30) days, as may be specified in the
               Stock Option Agreement), but in any event, no later than the
               expiration date of the Options.

        (b)     If the Participant is terminated because of death or Disability
                (or the Participant dies within three (3) months of such
                termination), then Participant's Options may be exercised only
                to the extent that such Options would have been exercisable by
                Participant on the Termination Date and must be exercised by
                Participant (or Participant's legal representative or authorized
                assignee) no later than twelve (12) months after the Termination
                Date (or such shorter time period, but not less than six (6)
                months, as may be specified in the Stock Option Agreement), but
                in any event no later than the expiration date of the Options.

        5.7 Limitations on Exercise. The Committee may specify a reasonable
minimum number of Shares that may be purchased on any exercise of an Option,
provided that such minimum number will not prevent Participant from exercising
the Option for the full number of Shares for which it is then exercisable.

        5.8 Limitations on ISOs. The aggregate Fair Market Value (determined as
of the date of grant) of Shares with respect to which ISOs are exercisable for
the first time by a Participant during any calendar year (under the Plan or
under any other incentive stock option plan of the Company or any Affiliate,
Parent or Subsidiary of the Company) shall not exceed $100,000. If the Fair
Market Value of Shares on the date of grant with respect to which ISOs are
exercisable for the first time by a Participant during any calendar year exceeds
$100,000, the Options for the first $100,000 worth of Shares to become
exercisable in such calendar year shall be ISOs and the Options for the amount
in excess of $100,000 that become exercisable in that calendar year shall be
NQSOs. In the event that the Code or the regulations promulgated thereunder are
amended after the Effective Date of the Plan to provide for a different limit on
the Fair Market Value of Shares permitted to be subject to ISOs, such different
limit shall be automatically incorporated herein and shall apply to any Options
granted after the effective date of such amendment.

        5.9 Modification, Extension or Renewal. The Committee may modify, extend
or renew outstanding Options and authorize the grant of new Options in
substitution therefor, provided that any such action may not, without the
written consent of Participant, impair any of Participant's rights under any
Option previously granted. Any outstanding ISO that is modified, extended,
renewed or otherwise altered shall be treated in accordance with Section 424(h)
of the Code. The Committee may reduce the Exercise Price of outstanding Options
without the consent of Participants affected by a written notice to them;
provided, however, that the Exercise Price may not be reduced below the minimum
Exercise Price that would be permitted under Section 5.4 of the Plan for Options
granted on the date the action is taken to reduce the Exercise Price.

        5.10 No Disqualification. Notwithstanding any other provision in the
Plan, no term of the Plan relating to ISOs shall be interpreted, amended or
altered, nor shall any discretion or 


                                       4
<PAGE>   5


authority granted under the Plan be exercised, so as to disqualify the Plan
under Section 422 of the Code or, without the consent of the Participant
affected, to disqualify any ISO under Section 422 of the Code.

6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the Company to sell
to an eligible person Shares that are subject to restrictions. The Committee
shall determine to whom an offer will be made, the number of Shares the person
may purchase, the price to be paid (the "Purchase Price"), the restrictions to
which the Shares shall be subject, and all other terms and conditions of the
Restricted Stock Award, subject to the following:

        6.1 Form of Restricted Stock Award. All purchases under a Restricted
Stock Award made pursuant to the Plan shall be evidenced by an Award Agreement
("Restricted Stock Purchase Agreement") that shall be in such form (which need
not be the same for each Participant) as the Committee shall from time to time
approve, and shall comply with and be subject to the terms and conditions of the
Plan. The offer of the Restricted Stock shall be accepted by the Participant's
execution and delivery of the Restricted Stock Purchase Agreement and full
payment for the Shares to the Company within thirty (30) days from the date of
the Restricted Stock Purchase Agreement is delivered to the person. If such
person does not execute and deliver the Restricted Stock Purchase Agreement
along with full payment for the Shares to the Company within thirty (30) days,
then the offer shall terminate, unless otherwise determined by the Committee.

        6.2 Purchase Price. The Purchase Price of Shares sold pursuant to a
Restricted Stock Award shall be determined by the Committee and shall be at
least 85% of the Fair Market Value of the Shares on the date the Restricted
Stock Award is granted, except in the case of a sale to a Ten Percent
Shareholder, in which case the Purchase Price shall be 100% of the Fair Market
Value. Payment of the Purchase Price may be made in accordance with Section 8 of
the Plan.

        6.3 Restrictions. Restricted Stock Awards shall be subject to such
restrictions as the Committee may impose. The Committee may provide for the
lapse of such restrictions in installments and may accelerate or waive such
restrictions, in whole or part, based on length of service, performance or such
other factors or criteria as the Committee may determine; provided that
Restricted Stock Awards containing restrictions which are subject to lapse at a
rate of less than 20% of the shares per year may be granted only to employees of
the Company earning at least $60,000 per year and having adequate sophistication
and sufficient empowerment to enable such employees to achieve the performance
goals.

7. STOCK BONUSES.

        7.1 Awards of Stock Bonuses. A Stock Bonus is an award of Shares (which
may consist of Restricted Stock) for services rendered to the Company or any
Parent, Subsidiary or Affiliate of the Company. A Stock Bonus may be awarded for
past services already rendered to the Company, or any Parent, Subsidiary or
Affiliate of the Company pursuant to an Award Agreement (the "Stock Bonus
Agreement") that shall be in such form (which need not be the same for each
Participant) as the Committee shall from time to time approve, and shall comply
with and be subject to the terms and conditions of the Plan. A Stock Bonus may
be awarded upon satisfaction of such performance goals as are set out in advance
in Participant's individual 




                                       5
<PAGE>   6

Award Agreement (the "Performance Stock Bonus Agreement") that shall be in such
form (which need not be the same for each Participant) as the Committee shall
from time to time approve, and shall comply with and be subject to the terms and
conditions of the Plan. Stock Bonuses may vary from Participant to Participant
and between groups of Participants, and may be based upon the achievement of the
Company, Parent, Subsidiary or Affiliate and/or individual performance factors
or upon such other criteria as the Committee may determine; provided, however,
that performance-based bonuses that do not vest at least as to 20% of the shares
per year shall be restricted to individuals earnings at least $60,000 per year
and having adequate sophistication and sufficient empowerment to enable such
individuals to achieve the performance goals.

        7.2 Terms of Stock Bonuses. The Committee shall determine the number of
Shares to be awarded to the Participant and whether such Shares shall be
Restricted Stock. If the Stock Bonus is being earned upon the satisfaction of
performance goals pursuant to a Performance Stock Bonus Agreement, then the
Committee shall determine: (a) the nature, length and starting date of any
period during which performance is to be measured (the "Performance Period") for
each Stock Bonus; (b) the performance goals and criteria to be used to measure
the performance, if any; (c) the number of Shares that may be awarded to the
Participant; and (d) the extent to which such Stock Bonuses have been earned.
Performance Periods may overlap and Participants may participate simultaneously
with respect to Stock Bonuses that are subject to different Performance Periods
and different performance goals and other criteria. The number of Shares may be
fixed or may vary in accordance with such performance goals and criteria as may
be determined by the Committee. The Committee may adjust the performance goals
applicable to the Stock Bonuses to take into account changes in law and
accounting or tax rules and to make such adjustments as the Committee deems
necessary or appropriate to reflect the impact of extraordinary or unusual
items, events or circumstances to avoid windfalls or hardships.

        7.3 Form of Payment. The earned portion of a Stock Bonus may be paid
currently or on a deferred basis with such interest or dividend equivalent, if
any, as the Committee may determine. Payment may be made in the form of cash,
whole Shares, including Restricted Stock, or a combination thereof, either in a
lump sum payment or in installments, all as the Committee shall determine.

        7.4 Termination During Performance Period. If a Participant is
Terminated during a Performance Period for any reason, then such Participant
shall be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Stock Bonus only to the extent earned as of the date of Termination in
accordance with the Performance Stock Bonus Agreement, unless the Committee
shall determine otherwise.

8. PAYMENT FOR SHARE PURCHASES.

        8.1 Payment. Payment for Shares purchased pursuant to the Plan may be
made in cash (by check) or, where expressly approved for the Participant by the
Committee and where permitted by law:

        (a)     by cancellation of indebtedness of the Company to the
                Participant;

                                       6
<PAGE>   7

        (b)     by surrender of Shares that either: (1) have been owned by
                Participant for more than six (6) months and have been paid for
                within the meaning of SEC Rule 144 (and, if such shares were
                purchased from the Company by use of a promissory note, such
                note has been fully paid with respect to such Shares); or (2)
                were obtained by Participant in the public market;

        (c)     by tender of a full recourse promissory note having such terms
                as may be approved by the Committee and bearing interest at a
                rate sufficient to avoid imputation of income under Sections 483
                and 1274 of the Code; provided, however, that Participants who
                are not employees of the Company shall not be entitled to
                purchase Shares with a promissory note unless the note is
                adequately secured by collateral other than the Shares;

        (d)     by waiver of compensation due or accrued to Participant for
                services rendered;

        (e)     by tender of property;

        (f)     with respect only to purchases upon exercise of an Option, and
                provided that a public market for the Company's stock exists:

               (1)    through a "same day sale" commitment from Participant and
                      a broker-dealer that is a member of the National
                      Association of Securities Dealers (an "NASD Dealer")
                      whereby the Participant irrevocably elects to exercise the
                      Option and to sell a portion of the Shares so purchased to
                      pay for the Exercise Price, and whereby the NASD Dealer
                      irrevocably commits upon receipt of such Shares to forward
                      the Exercise Price directly to the Company; or

               (2)    through a "margin" commitment from Participant and an NASD
                      Dealer whereby Participant irrevocably elects to exercise
                      the Option and to pledge the Shares so purchased to the
                      NASD Dealer in a margin account as security for a loan
                      from the NASD Dealer in the amount of the Exercise Price,
                      and whereby the NASD Dealer irrevocably commits upon
                      receipt of such Shares to forward the exercise price
                      directly to the Company;
        or

        (g)     by any combination of the foregoing.

        8.2 Loan Guarantees. The Committee may help the Participant pay for
Shares purchased under the Plan by authorizing a guarantee by the Company of a
third-party loan to the Participant.

9. WITHHOLDING TAXES.

        9.1 Withholding Generally. Whenever Shares are to be issued in
satisfaction of Awards granted under the Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements 





                                       7
<PAGE>   8

prior to the delivery of any certificate or certificates for such Shares.
Whenever, under the Plan, payments in satisfaction of Awards are to be made in
cash, such payment shall be net of an amount sufficient to satisfy federal,
state, and local withholding tax requirements.

        9.2 Stock Withholding. When, under applicable tax laws, a Participant
incurs tax liability in connection with the exercise or vesting of any Award
that is subject to tax withholding and the Participant is obligated to pay the
Company the amount required to be withheld, the Committee may in its sole
discretion, allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined (the "Tax Date"). All elections by a Participant to
have Shares withheld for this purpose shall be made in writing in a form
acceptable to the Committee and shall be subject to the following restrictions:

        (a)     the election must be made on or prior to the applicable Tax
                Date;

        (b)     once made, then except as provided below, the election shall be
                irrevocable as to the particular Shares as to which the election
                is made;

        (c)     all elections shall be subject to the consent or disapproval of
                the Committee;

        (d)     if the Participant is an Insider and if the Company is subject
                to Section 16(b) of the Exchange Act: (1) the election may not
                be made within six (6) months of the date of grant of the Award,
                except as otherwise permitted by SEC Rule 16b-3(e) under the
                Exchange Act, and (2) either (A) the election to use stock
                withholding must be irrevocably made at least six (6) months
                prior to the Tax Date (although such election may be revoked at
                any time at least six (6) months prior to the Tax Date) or (B)
                the exercise of the Option or election to use stock withholding
                must be made in the ten (10) day period beginning on the third
                day following the release of the Company's quarterly or annual
                summary statement of sales or earnings;

        (e)     in the event that the Tax Date is deferred until six (6) months
                after the delivery of Shares under Section 83(b) of the Code,
                the Participant shall receive the full number of Shares with
                respect to which the exercise occurs, but such Participant shall
                be unconditionally obligated to tender back to the Company the
                proper number of Shares on the Tax Date.

10. PRIVILEGES OF STOCK OWNERSHIP.

        10.1 Voting and Dividends. No Participant shall have any of the rights
of a shareholder with respect to any Shares until the Shares are issued to the
Participant. After Shares are issued to the Participant, the Participant shall
be a shareholder and have all the rights of a shareholder with respect to such
Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become 



                                       8
<PAGE>   9

entitled to receive with respect to such Shares by virtue of a stock dividend,
stock split or any other change in the corporate or capital structure of the
Company shall be subject to the same restrictions as the Restricted Stock;
provided, further, that the Participant shall have no right to retain such stock
dividends or stock distributions with respect to Shares that are later
repurchased at the Participant's original Purchase Price pursuant to Section 12.

        10.2 Financial Statements. The Company shall provide financial
statements to each Participant prior to such Participant's purchase of Shares
under the Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company shall not be
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

11. TRANSFERABILITY. Awards granted under the Plan, and any interest therein,
shall not be transferable or assignable by Participant, and may not be made
subject to execution, attachment or similar process, otherwise than by will or
by the laws of descent and distribution or as consistent with the specific Plan
and Award Agreement provisions relating thereto. During the lifetime of the
Participant an Award shall be exercisable only by the Participant, and any
elections with respect to an Award, may be made only by the Participant.

12. RESTRICTIONS ON SHARES. At the discretion of the Committee, the Company may
reserve to itself and/or its assignee(s) in the Award Agreement (a) a right of
first refusal to purchase all Shares that a Participant (or a subsequent
transferee) may propose to transfer to a third party, and/or (b) a right to
repurchase all, or if the Participant consents a portion, of the Shares held by
a Participant following such Participant's Termination at any time within ninety
(90) days after the later of Participant's Termination Date and the date
Participant purchases Shares under the Plan, for cash or cancellation of
purchase money indebtedness, at: (A) with respect to Shares that are "Vested"
(as defined in the Award Agreement), the higher of: (l) Participant's original
Purchase Price, or (2) the Fair Market Value of such Shares on Participant's
Termination Date, provided, such right of repurchase terminates when the
Company's securities become publicly traded; or (B) with respect to Shares that
are not "Vested" (as defined in the Award Agreement), at the Participant's
original Purchase Price, provided, that except with respect to Awards granted to
employees of the Company earning at least $60,000 per year and having adequate
sophistication and sufficient empowerment to enable such employees to achieve
the performance goals, the right to repurchase at the original Purchase Price
lapses at the rate of at least 20% per year over 5 years from the date the
Shares were purchased, and if the right to repurchase is assignable, the
assignee must pay the Company, upon assignment of the right to repurchase, cash
equal to the excess of the Fair Market Value of the Shares over the original
Purchase Price.

13. CERTIFICATES. All certificates for Shares or other securities delivered
under the Plan shall be subject to such stock transfer orders, legends and other
restrictions as the Committee may deem necessary or advisable, including
restrictions under any applicable federal, state or foreign securities law, or
any rules, regulations and other requirements of the SEC or any stock exchange
or automated quotation system upon which the Shares may be listed.

14. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a Participant's
Shares, the Committee may require the Participant to deposit all certificates
representing Shares, 



                                       9
<PAGE>   10

together with stock powers or other instruments of transfer approved by the
Committee, appropriately endorsed in blank, with the Company or an agent
designated by the Company to hold in escrow until such restrictions have lapsed
or terminated, and the Committee may cause a legend or legends referencing such
restrictions to be placed on the certificates. Any Participant who is permitted
to execute a promissory note as partial or full consideration for the purchase
of Shares under the Plan shall be required to pledge and deposit with the
Company all or part of the Shares so purchased as collateral to secure the
payment of Participant's obligation to the Company under the promissory note;
provided, however, that the Committee may require or accept other or additional
forms of collateral to secure the payment of such obligation and, in any event,
the Company shall have full recourse against the Participant under the
promissory note notwithstanding any pledge of the Participant's Shares or other
collateral. In connection with any pledge of the Shares, Participant shall be
required to execute and deliver a written pledge agreement in such form as the
Committee shall from time to time approve. The Shares purchased with the
promissory note may be released from the pledge on a prorata basis as the
promissory note is paid.

15. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time or from time
to time, authorize the Company, with the consent of the respective Participants,
to issue new Awards in exchange for the surrender and cancellation of any or all
outstanding Awards. The Committee may at any time buy from a Participant an
Award previously granted with payment in cash, Shares (including Restricted
Stock) or other consideration, based on such terms and conditions as the
Committee and the Participant shall agree.

16. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award shall not be
effective unless such Award is in compliance with all applicable federal and
state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed, as they are in effect on the date of grant of the
Award and also on the date of exercise or other issuance. Notwithstanding any
other provision in the Plan, the Company shall have no obligation to issue or
deliver certificates for Shares under the Plan prior to (a) obtaining any
approvals from governmental agencies that the Company determines are necessary
or advisable, and/or (b) completion of any registration or other qualification
of such shares under any state or federal law or ruling of any governmental body
that the Company determines to be necessary or advisable. The Company shall be
under no obligation to register the Shares with the SEC or to effect compliance
with the registration, qualification or listing requirements of any state
securities laws, stock exchange or automated quotation system, and the Company
shall have no liability for any inability or failure to do so.

17. NO OBLIGATION TO EMPLOY. Nothing in the Plan or any Award granted under the
Plan shall confer or be deemed to confer on any Participant any right to
continue in the employ of, or to continue any other relationship with, the
Company or any Parent, Subsidiary or Affiliate of the Company or limit in any
way the right of the Company or any Parent, Subsidiary or Affiliate of the
Company to terminate Participant's employment or other relationship at any time,
with or without cause.

18. CORPORATE TRANSACTIONS.

        18.1 Assumption or Replacement of Awards by Successor. In the event of
(a) a merger or consolidation in which the Company is not the surviving
corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the shareholders of
the Company and the Awards granted under the Plan are assumed or replaced by the
successor corporation, which assumption shall be binding on all Participants),
(b) a dissolution or liquidation of the Company, (c) the sale of substantially
all of the assets of the Company, or (d) any other transaction which qualifies
as a "corporate transaction" under Section 424(a) of the Code wherein the
shareholders of the Company give up all of their equity interest in the Company
(except for the acquisition, sale or transfer of all or substantially all of the
outstanding shares of the Company) any or all outstanding Awards may be assumed
or replaced by the successor corporation (if any), which assumption or
replacement shall be binding on all Participants. In the alternative, the
successor corporation may substitute equivalent Awards or provide substantially
similar consideration to Participants as was provided to shareholders (after
taking into account the existing provisions of the Awards). The successor
corporation may also issue, in place of outstanding Shares of the Company held
by the Participant, substantially similar shares or other property subject to
repurchase restrictions no less favorable to the Participant.

        In the event such successor corporation, if any, refuses to assume or
substitute the Options, as provided above, pursuant to a transaction described
in this Subsection 18.1, such Awards shall expire in connection with such
transaction at such time and such conditions as the Board shall determine.

        18.2 Other Treatment of Awards. Subject to any greater rights granted to
Participants under the foregoing provisions of this Section 18, in the event of
the occurrence of any transaction described in Section 18.1, any outstanding
Awards shall be treated as provided in the applicable agreement or plan of
merger, consolidation, dissolution, liquidation, sale of assets or other
"corporate transaction."

        18.3 Assumption of Awards by the Company. The Company, from time to
time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either (a) granting an Award under the Plan in substitution of
such other company's award, or (b) assuming such award as if it had been granted
under the Plan if the terms of such assumed award could be applied to an Award
granted under the Plan. Such substitution or assumption shall be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under the Plan if the other company had applied the rules of
the Plan to such grant. In the event the Company assumes an award granted by
another company, the terms and conditions of such award shall remain unchanged
(except that the exercise price and the number and nature of Shares issuable
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code). In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

                                       11
<PAGE>   12

19. ADOPTION AND SHAREHOLDER APPROVAL. The Plan shall become effective on the
date that it is adopted by the Board (the "Effective Date"). The Plan shall be
approved by the shareholders of the Company (excluding Shares issued pursuant to
this Plan), consistent with applicable laws, within twelve months before or
after the Effective Date. Upon the Effective Date, the Board may grant Awards
pursuant to the Plan; provided, however, that: (a) no Option may be exercised
prior to initial shareholder approval of the Plan; (b) no Option granted
pursuant to an increase in the number of Shares approved by the Board shall be
exercised prior to the time such increase has been approved by the shareholders
of the Company; and (c) in the event that shareholder approval is not obtained
within the time period provided herein, all Awards granted hereunder shall be
cancelled, any Shares issued pursuant to any Award shall be cancelled and any
purchase of Shares hereunder shall be rescinded. After the Company becomes
subject to Section 16(b) of the Exchange Act, the Company will comply with the
requirements of Rule 16b-3 (or its successor), as amended, with respect to
shareholder approval.

20. TERM OF PLAN. The Plan will terminate ten (10) years from the Effective Date
or, if earlier, the date of shareholder approval.

21. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time terminate or
amend the Plan in any respect, including without limitation amendment of any
form of Award Agreement or instrument to be executed pursuant to the Plan;
provided, however, that the Board shall not, without the approval of the
shareholders of the Company, amend the Plan in any manner that requires such
shareholder approval pursuant to the Code or the regulations promulgated
thereunder as such provisions apply to ISO plans or pursuant to the Exchange Act
or Rule 16b-3 (or its successor), as amended, thereunder.

22. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan by the Board,
the submission of the Plan to the shareholders of the Company for approval, nor
any provision of the Plan shall be construed as creating any limitations on the
power of the Board to adopt such additional compensation arrangements as it may
deem desirable, including, without limitation, the granting of stock options and
bonuses otherwise than under the Plan, and such arrangements may be either
generally applicable or applicable only in specific cases.

23. GOVERNING LAW. The Plan and all agreements, documents and instruments
entered into pursuant to the Plan shall be governed by and construed in
accordance with the internal laws of the State of California, excluding that
body of law pertaining to conflict of laws.

        2. EXERCISE PERIOD.

                2.1 Exercise Period of Option. Provided Participant continues to
provide services to the Company or any Subsidiary, Parent or Affiliate of the
Company throughout the specified period, the Option will become vested and
exercisable as to portions of the Shares as follows: (a) This Option shall not
vest nor be exercisable with respect to any of the Shares until the First
Vesting Date set forth on page 1 hereof (the "First Vesting Date"); (b) on the
First Vesting Date the Option will become vested and exercisable as to
twenty-five percent (25%) of the Shares and (c) thereafter at the end of each
full succeeding month the Option shall become vested and exercisable as to two
and eighty-three one thousandths percent (2.083%) of the Shares. If application
of the vesting percentage causes a fractional Share, such Share shall be rounded
down to a whole Share.

                2.2 Expiration. The Option shall expire on the Expiration Date
set forth above and must be exercised, if at all, on or before the Expiration
Date.

        3. TERMINATION.

                3.1 Termination for Any Reason Except Death or Disability. If
Participant is Terminated for any reason, except death or Disability, the
Option, to the extent (and only to the extent) that it would have been
exercisable by Participant on the Termination Date, may be exercised by
Participant no later than three (3) months after the Termination Date, but in
any event no later than the Expiration Date.

                3.2 Termination Because of Death or Disability. If Participant
is Terminated because of death or Disability of Participant, the Option, to the
extent that it is exercisable by Participant on the Termination Date, may be
exercised by Participant (or Participant's legal representative) no later than
twelve (12) months after the Termination Date, but in any event no later than
the Expiration Date.

                3.3 No Obligation to Employ. Nothing in the Plan or this
Agreement shall confer on Participant any right to continue in the employ of, or
other relationship with, the Company or any Parent, Subsidiary or Affiliate of
the Company, or limit in any way the right of the Company or any Parent,
Subsidiary or Affiliate of the Company to terminate Participant's employment or
other relationship at any time, with or without cause.

        4. MANNER OF EXERCISE.

                4.1 Stock Option Exercise Agreement. To exercise this Option,
Participant (or in the case of exercise after Participant's death, Participant's
executor, administrator, heir or legatee, as the case may be) must deliver to
the Company an executed stock option exercise agreement substantially in the
form attached hereto as Exhibit A, or in such other form as may be approved by
the Company from time to time (the "Exercise Agreement"), which shall set forth,
inter alia, Participant's election to exercise the Option, the number of Shares
being purchased, any restrictions imposed on the Shares and any representations,
warranties and agreements regarding Participant's investment intent and access
to information as 


<PAGE>   17

may be required by the Company to comply with applicable securities laws. If
someone other than Participant exercises the Option, then such person must
submit documentation reasonably acceptable to the Company that such person has
the right to exercise the Option.

                4.2 Limitations on Exercise. The Option may not be exercised
unless such exercise is in compliance with all applicable federal and state
securities laws, as they are in effect on the date of exercise. The Option may
not be exercised as to fewer than 100 Shares unless it is exercised as to all
Shares as to which the Option is then exercisable.

                4.3 Payment. The Exercise Agreement shall be accompanied by full
payment of the Exercise Price for the Shares being purchased in cash (by check),
or where permitted by law:

                (a)     by cancellation of indebtedness of the Company to the
                        Participant;

                (b)     at the discretion of the Committee, by surrender of
                        shares of the Company's Common Stock that either: (1)
                        have been owned by Participant for more than six (6)
                        months and have been paid for within the meaning of SEC
                        Rule 144 and, if such shares were purchased from the
                        Company by use of a promissory note, such note has been
                        fully paid with respect to such shares); or (2) were
                        obtained by Participant in the open public market; and
                        (3) are clear of all liens, claims, encumbrances or
                        security interests;

                (c)     by waiver of compensation due or accrued to Participant
                        for services rendered;

                (d)     provided that a public market for the Company's stock
                        exists, (1) through a "same day sale" commitment from
                        Participant and a broker-dealer that is a member of the
                        National Association of Securities Dealers (an "NASD
                        Dealer") whereby Participant irrevocably elects to
                        exercise the Option and to sell a portion of the Shares
                        so purchased to pay for the Exercise Price and whereby
                        the NASD Dealer irrevocably commits upon receipt of such
                        Shares to forward the Exercise Price directly to the
                        Company, or (2) through a "margin" commitment -- from
                        Participant and an NASD Dealer whereby Participant
                        irrevocably elects to exercise the Option and to pledge
                        the Shares so purchased to the NASD Dealer in a margin
                        account as security for a loan from the NASD Dealer in
                        the amount of the Exercise Price, and whereby the NASD
                        Dealer irrevocably commits upon receipt of such Shares
                        to forward the Exercise Price directly to the Company;
                        or

                (e)     by any combination of the foregoing.

                4.4 Tax Withholding. Prior to the issuance of the Shares upon
exercise of the Option, Participant must pay or provide for any applicable
federal, state and local 



<PAGE>   18

withholding obligations of the Company. If the Committee permits, Participant
may provide for payment of withholding taxes upon exercise of the Option by
requesting that the Company retain Shares with a Fair Market Value equal to the
minimum amount of taxes required to be withheld. In such case, the Company shall
issue the net number of Shares to the Participant by deducting the Shares
retained from the Shares issuable upon exercise.

                4.5 Issuance of Shares. Provided that the Exercise Agreement and
payment are in form and substance satisfactory to counsel for the Company, the
Company shall issue the Shares registered in the name of Participant,
Participant's authorized assignee, or Participant's legal representative, and
shall deliver certificates representing the Shares with the appropriate legends
affixed thereto.

        5. NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. If the Option is
an ISO, and if Participant sells or otherwise disposes of any of the Shares
acquired pursuant to the ISO on or before the later of (1) the date two years
after the Date of Grant, and (2) the date one year after transfer of such Shares
to Participant upon exercise of the Option, Participant shall immediately notify
the Company in writing of such disposition. Participant agrees that Participant
may be subject to income tax withholding by the Company on the compensation
income recognized by Participant from the early disposition by payment in cash
or out of the current wages or other compensation payable to Participant.

        6. COMPLIANCE WITH LAWS AND REGULATIONS. The exercise of the Option and
the issuance and transfer of Shares shall be subject to compliance by the
Company and Participant with all applicable requirements of federal and state
securities laws and with all applicable requirements of any stock exchange on
which the Company's Common Stock may be listed at the time of such issuance or
transfer. Participant understands that the Company is under no obligation to
register or qualify the Shares with the Securities and Exchange Commission, any
state securities commission or any stock exchange to effect such compliance.

        7. NONTRANSFERABILITY OF OPTION. The Option may not be transferred in
any manner other than by will or by the laws of descent and distribution and may
be exercised during the lifetime of Participant only by Participant. The terms
of the Option shall be binding upon the executors, administrators, successors
and assigns of Participant.

        8. TAX CONSEQUENCES. Set forth below is a brief summary as of the Date
of Grant of some of the federal and California tax consequences of exercise of
the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. PARTICIPANT
SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE
SHARES.

                8.1 Exercise of ISO. If the Option qualifies as an ISO, there
will be no regular federal or California income tax liability upon the exercise
of the Option, although the excess, if any, of the fair market value of the
Shares on the date of exercise over the Exercise Price will be treated as a tax
preference item for federal income tax purposes and may subject the Participant
to the alternative minimum tax in the year of exercise.
<PAGE>   19

                8.2 Exercise of Nonqualified Stock Option. If the Option does
not qualify as an ISO, there may be a regular federal and California income tax
liability upon the exercise of the Option. Participant will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the fair market value of the Shares on the date of exercise
over the Exercise Price. The Company will be required to withhold from
Participant's compensation or collect from Participant and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

                8.3 Disposition of Shares. If the Shares are held for more than
twelve (12) months after the date of the transfer of the Shares pursuant to the
exercise of the Option and, in the case of an ISO, are disposed of more than two
years after the Date of Grant, any gain realized on disposition of the Shares
will be treated as long term capital gain for federal and California income tax
purposes. If Shares purchased under an ISO are disposed of within the applicable
one year or two year period, 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 Fair Market Value of the Shares on the date of
exercise over the Exercise Price. The Company may be required to withhold from
Participant's compensation or collect from Participant and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

        9. PRIVILEGES OF STOCK OWNERSHIP. Participant shall not have any of the
rights of a shareholder with respect to any Shares until Participant exercises
the Option and pays the Exercise Price.

        10. INTERPRETATION. Any dispute regarding the interpretation of this
Agreement shall be submitted by Participant or the Company to the Committee for
review. The resolution of such a dispute by the Committee shall be final and
binding on the Company and Participant.

        11. ENTIRE AGREEMENT. The Plan is incorporated herein by reference. This
Agreement and the Plan constitute the entire agreement of the parties and
supersede all prior undertakings and agreements with respect to the subject
matter hereof.

        12. NOTICES. Any notice required to be given or delivered to the Company
under the terms of this Agreement shall be in writing and addressed to the
Corporate Secretary of the Company at its principal corporate offices. Any
notice required to be given or delivered to Participant shall be in writing and
addressed to Participant at the address indicated above or to such other address
as such party may designate in writing from time to time to the Company. All
notices shall be deemed to have been given or delivered upon: personal delivery;
three (3) days after deposit in the United States mail by certified or
registered mail (return receipt requested); one (1) business day after deposit
with any return receipt express courier (prepaid); or one (1) business day after
transmission by rapifax or telecopier.

        13. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights
under this Agreement. This Agreement shall be binding upon and inure to the
benefit of the successors 


<PAGE>   20

and assigns of the Company. Subject to the restrictions on transfer set forth
herein, this Agreement shall be binding upon Participant and Participant's
heirs, executors, administrators, legal representatives, successors and assigns.

            14. GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of California as such laws are applied
to agreements between California residents entered into and to be performed
entirely within California.

            15. ACCEPTANCE. Participant hereby acknowledges receipt of a copy of
the Plan and this Agreement. Participant has read and understands the terms and
provisions thereof, and accepts the Option subject to all the terms and
conditions of the Plan and this Agreement. Participant acknowledges that there
may be adverse tax consequences upon exercise of the Option or disposition of
the Shares and that Participant should consult a tax adviser prior to such
exercise or disposition.

            IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed in duplicate by its duly authorized representative and Participant has
executed this Agreement in duplicate as of the Date of Grant.

Company (i) this Exercise Agreement, (ii) two (2) copies of a blank Stock Power
and Assignment Separate from Stock Certificate in the form of Exhibit 1 attached
hereto (the "Stock Powers"), both executed by Purchaser (and Purchaser's spouse,
if any), (iii) if Purchaser is married, a Consent of Spouse in the form of
Exhibit 2 attached hereto (the "Spouse Consent") executed by Purchaser's spouse,
and (iv) the Purchase Price.

                2.2 DELIVERIES BY THE COMPANY. Upon its receipt of the Purchase
Price and all the documents to be executed and delivered by Purchaser to the
Company under Section 2.1, the Company will issue a duly executed stock
certificate evidencing the Shares in the name of Purchaser, to be placed in
escrow as provided in Section 10 until expiration or termination of the
Company's Right of First Refusal described in Section 8.

        3. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser represents and
warrants to the Company that:

                3.1 AGREES TO TERMS OF THE PLAN. Purchaser has received a copy
of the Plan and the Stock Option Agreement, has read and understands the terms
of the Plan, the Stock Option Agreement and this Exercise Agreement, and agrees
to be bound by their terms and conditions. Purchaser acknowledges that there may
be adverse tax consequences upon exercise of the Option or disposition of the
Shares, and that Purchaser should consult a tax adviser prior to such exercise
or disposition.

                3.2 PURCHASE FOR OWN ACCOUNT FOR INVESTMENT. Purchaser is
purchasing the Shares for Purchaser's own account for investment purposes only
and not with a view to, or for sale in connection with, a distribution of the
Shares within the meaning of the Securities Act of 1933, as amended (the
"Securities Act"). Purchaser has no present intention of selling or otherwise
disposing of all or any portion of the Shares and no one other than Purchaser
has any beneficial ownership of any of the Shares.

                3.3 ACCESS TO INFORMATION. Purchaser has had access to all
information regarding the Company and its present and prospective business,
assets, liabilities and financial condition that Purchaser reasonably considers
important in making the decision to purchase the Shares, and Purchaser has had
ample opportunity to ask questions of the Company's representatives concerning
such matters and this investment.

                3.4 UNDERSTANDING OF RISKS. Purchaser is fully aware of: (i) the
highly speculative nature of the investment in the Shares; (ii) the financial
hazards involved; (iii) the lack of liquidity of the Shares and the restrictions
on transferability of the Shares (e.g., that Purchaser may not be able to sell
or dispose of the Shares or use them as collateral for loans); (iv) the
qualifications and backgrounds of the management of the Company; and (v) the tax
consequences of investment in the Shares. Purchaser is capable of evaluating the
merits and risks of this investment, has the ability to protect Purchaser's own
interests in this transaction and is financially capable of bearing a total loss
of this investment.
<PAGE>   24

                3.5 NO GENERAL SOLICITATION. At no time was Purchaser presented
with or solicited by any publicly issued or circulated newspaper, mail, radio,
television or other form of general advertising or solicitation in connection
with the offer, sale and purchase of the Shares.

        4. COMPLIANCE WITH SECURITIES LAWS.

                4.1 COMPLIANCE WITH FEDERAL SECURITIES LAWS. Purchaser
understands and acknowledges that the Shares have not been registered with the
Securities and Exchange Commission ("SEC") under the Securities Act and that,
notwithstanding any other provision of the Stock Option Agreement to the
contrary, the exercise of any rights to purchase any Shares is expressly
conditioned upon compliance with the Securities Act and all applicable state
securities laws. Purchaser agrees to cooperate with the Company to ensure
compliance with such laws. The Shares are being issued under the Securities Act
pursuant to (the Company will check the applicable box):

             [ ] the exemption provided by SEC Rule 701; 
             [ ] the exemption provided by SEC Rule 504; 
             [ ] Section 4(2) of the Securities Act; 
             [ ] other: ____________________________.

             4.2 COMPLIANCE WITH CALIFORNIA SECURITIES LAWS. THE SALE OF THE
SECURITIES THAT ARE THE SUBJECT OF THIS EXERCISE AGREEMENT, IF NOT YET QUALIFIED
WITH THE CALIFORNIA COMMISSIONER OF CORPORATIONS AND NOT EXEMPT FROM SUCH
QUALIFICATION, IS SUBJECT TO SUCH QUALIFICATION, AND THE ISSUANCE OF SUCH
SECURITIES, AND THE RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO
SUCH QUALIFICATION IS UNLAWFUL UNLESS THE SALE IS EXEMPT. THE RIGHTS OF THE
PARTIES TO THIS EXERCISE AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH
QUALIFICATION BEING OBTAINED OR AN EXEMPTION BEING AVAILABLE.

        5. RESTRICTED SECURITIES.

             5.1 NO TRANSFER UNLESS REGISTERED OR EXEMPT. Purchaser understands
that Purchaser may not transfer any Shares unless such Shares are registered
under the Securities Act or qualified under applicable state securities laws or
unless, in the opinion of counsel to the Company, exemptions from such
registration and qualification requirements are available. Purchaser understands
that only the Company may file a registration statement with the SEC and that
the Company is under no obligation to do so with respect to the Shares.
Purchaser has also been advised that exemptions from registration and
qualification may not be available or may not permit Purchaser to transfer all
or any of the Shares in the amounts or at the times proposed by Purchaser.

             5.2 SEC RULE 144. In addition, Purchaser has been advised that SEC
Rule 144 promulgated under the Securities Act, which permits certain limited
sales of unregistered securities, is not presently available with respect to the
Shares and, in any event, requires that the 


<PAGE>   25

Shares be held for a minimum of two years, and in certain cases three years,
after they have been purchased and paid for (within the meaning of Rule 144).
Purchaser understands that Rule 144 may indefinitely restrict transfer of the
Shares so long as Purchaser remains an "affiliate" of the Company or if "current
public information" about the Company (as defined in Rule 144) is not publicly
available.

             5.3 SEC RULE 701. The Shares may become freely tradeable by
non-affiliates if issued pursuant to SEC Rule 701 promulgated under the
Securities Act (under limited conditions regarding the method of sale) 90 days
after the first sale of Common Stock of the Company to the general public
pursuant to a registration statement filed with and declared effective by the
SEC, subject to the lengthier market standoff agreement contained in Section 7
of this Exercise Agreement or any other agreement entered into by Purchaser.
Affiliates must comply with the provisions (other than the holding period
requirements) of Rule 144.

             5.4 STATE LAW RESTRICTIONS ON TRANSFER. Purchaser understands that
transfer of the Shares may be restricted by Section 260.141.11 of the Rules of
the California Commissioner of Corporations, a copy of which is attached hereto
as Exhibit 3, and that the certificate(s) representing the Shares may bear a
legend to that effect.

        6. RESTRICTIONS ON TRANSFERS.

             6.1 DISPOSITION OF SHARES. Purchaser hereby agrees that Purchaser
shall make no disposition of the Shares (other than as permitted by this
Agreement) unless and until:

                        (a) Purchaser shall have notified the Company of the
proposed disposition and provided a written summary of the terms and conditions
of the proposed disposition;

                        (b) Purchaser shall have complied with all requirements
of this Exercise Agreement applicable to the disposition of the Shares;

                        (c) Purchaser shall have provided the Company with
written assurances, in form and substance satisfactory to counsel for the
Company, that (i) the proposed disposition does not require registration of the
Shares under the Securities Act or (ii) all appropriate action necessary for
compliance with the registration requirements of the Securities Act or of any
exemption from registration available under the Securities Act (including Rule
144) has been taken; and

                        (d) Purchaser shall have provided the Company with
written assurances, in form and substance satisfactory to the Company, that the
proposed disposition will not result in the contravention of any transfer
restrictions applicable to the Shares pursuant to the provisions of the
Commissioner Rules identified in Section 4.2.

             6.2 RESTRICTION ON TRANSFER. Purchaser shall not transfer, assign,
grant a lien or security interest in, pledge, hypothecate, encumber or otherwise
dispose of any of the Shares which are subject to the Company's Right of First
Refusal, except as permitted by this Agreement.
<PAGE>   26

             6.3 TRANSFEREE OBLIGATIONS. Each person (other than the Company) to
whom the Shares are transferred by means of one of the permitted transfers
specified in this Agreement must, as a condition precedent to the validity of
such transfer, acknowledge in writing to the Company that such person is bound
by the provisions of this Exercise Agreement and that the transferred shares are
subject to (i) the Company's Right of First Refusal granted hereunder and (ii)
the market stand-off provisions of Section 7, to the same extent such shares
would be so subject if retained by the Purchaser.

        7. MARKET STANDOFF AGREEMENT. Purchaser agrees in connection with any
registration of the Company's securities that, upon the request of the Company
or the underwriters managing any public offering of the Company's securities,
Purchaser will not sell or otherwise dispose of any Shares without the prior
written consent of the Company or such underwriters, as the case may be, for
such period of time (not to exceed 180 days) after the effective date of such
registration requested by such managing underwriters and subject to all
restrictions as the Company or the underwriters may specify.

        8. COMPANY'S RIGHT OF FIRST REFUSAL. Before any Shares held by Purchaser
or any transferee of such Shares (either being sometimes referred to herein as
the "Holder") may be sold or otherwise transferred (including without limitation
a transfer by gift or operation of law), the Company and/or its assignee(s)
shall have an assignable right of first refusal to purchase the Shares to be
sold or transferred (the "Offered Shares") on the terms and conditions set forth
in this Section (the "Right of First Refusal").

             8.1 NOTICE OF PROPOSED TRANSFER. The Holder of the Offered Shares
shall deliver to the Company a written notice (the "Notice") stating: (i) the
Holder's bona fide intention to sell or otherwise transfer the Offered Shares;
(ii) the name of each proposed bona fide purchaser or other transferee
("Proposed Transferee"); (iii) the number of Offered Shares to be transferred to
each Proposed Transferee; (iv) the bona fide cash price or other consideration
for which the Holder proposes to transfer the Offered Shares (the "Offered
Price"); and (v) that the Holder will offer to sell the Offered Shares to the
Company and/or its assignee(s) at the Offered Price as provided in this Section.

             8.2 EXERCISE OF RIGHT OF FIRST REFUSAL. At any time within thirty
(30) days after the date of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all of the Offered
Shares proposed to be transferred to any one or more of the Proposed Transferees
named in the Notice, at the purchase price determined as specified below.

             8.3 PURCHASE PRICE. The purchase price for the Offered Shares
purchased under this Section will be the Offered Price. If the Offered Price
includes consideration other than cash, then the cash equivalent value of the
non-cash consideration shall conclusively be deemed to be the value of such
non-cash consideration as determined in good faith by the Company's Board of
Directors.
<PAGE>   27

             8.4 PAYMENT. Payment of the purchase price for Offered Shares will
be payable, at the option of the Company and/or its assignee(s) (as applicable),
by check or by cancellation of all or a portion of any outstanding indebtedness
of the Holder to the Company (or to such assignee, in the case of a purchase of
Offered Shares by such assignee) or by any combination thereof. The purchase
price will be paid without interest within sixty (60) days after the Company's
receipt of the Notice, or, at the option of the Company and/or its assignee(s),
in the manner and at the time(s) set forth in the Notice.

             8.5 HOLDER'S RIGHT TO TRANSFER. If all of the Offered Shares
proposed in the Notice to be transferred to a given Proposed Transferee are not
purchased by the Company and/or its assignee(s) as provided in this Section,
then the Holder may sell or otherwise transfer such Offered Shares to that
Proposed Transferee at the Offered Price or at a higher price, provided that
such sale or other transfer is consummated within 120 days after the date of the
Notice, and provided further, that (i) any such sale or other transfer is
effected in compliance with all applicable securities laws and (ii) the Proposed
Transferee agrees in writing that the provisions of this Section will continue
to apply to the Offered Shares in the hands of such Proposed Transferee. If the
Offered Shares described in the Notice are not transferred to the Proposed
Transferee within such 120 day period, then a new Notice must be given to the
Company, and the Company will again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

             8.6 EXEMPT TRANSFERS. Notwithstanding anything to the contrary in
this Section, the following transfers of Shares will be exempt from the Right of
First Refusal: (i) the transfer of any or all of the Shares during Purchaser's
lifetime by gift or on Purchaser's death by will or intestacy to Purchaser's
"immediate family" (as defined below) or to a trust for the benefit of Purchaser
or Purchaser's immediate family, provided that each transferee or other
recipient agrees in a writing satisfactory to the Company that the provisions of
this Section will continue to apply to the transferred Shares in the hands of
such transferee or other recipient; (ii) any transfer of Shares made pursuant to
a statutory merger or statutory consolidation of the Company with or into
another corporation or corporations (except that the Right of First Refusal will
continue to apply thereafter to such Shares, in which case the surviving
corporation of such merger or consolidation shall succeed to the rights of the
Company under this Section unless the agreement of merger or consolidation
expressly otherwise provides); or (iii) any transfer of Shares pursuant to the
winding up and dissolution of the Company. As used herein, the term "immediate
family" will mean Purchaser's spouse, the lineal descendant or antecedent,
father, mother, brother or sister, adopted child or grandchild of the Purchaser
or the Purchaser's spouse, or the spouse of any child, adopted child, grandchild
or adopted grandchild of Purchaser or the Purchaser's spouse.

             8.7 TERMINATION OF RIGHT OF FIRST REFUSAL. The Right of First
Refusal will terminate as to all Shares on the effective date of the first sale
of Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the SEC under the Securities Act
(other than a registration statement relating solely to the issuance of Common
Stock pursuant to a business combination or an employee incentive or benefit
plan).

        9. RIGHTS AS SHAREHOLDER. Subject to the terms and conditions of this
Exercise Agreement, Purchaser will have all of the rights of a shareholder of
the Company with respect to the Shares from and after the date that Purchaser
delivers payment of the Purchase Price until such time as Purchaser disposes of
the Shares or the Company and/or its assignee(s) exercise(s) the Right of First
Refusal. Upon an exercise of the Right of First Refusal, Purchaser will have no
further rights as a holder of the Shares so purchased upon such exercise, except
the right to receive payment for the Shares so purchased in accordance with the
provisions of this Exercise Agreement, and Purchaser will promptly surrender the
stock certificate(s) evidencing the Shares so purchased to the Company for
transfer or cancellation.

        10. ESCROW. As security for Purchaser's faithful performance of this
Agreement, Purchaser agrees, immediately upon receipt of the stock
certificate(s) evidencing the Shares, to deliver such certificate(s), together
with the Stock Powers executed by Purchaser and by Purchaser's spouse, if any
(with the date and number of Shares left blank), to the Secretary of the Company
or other designee of the Company ("Escrow Holder"), who is hereby appointed to
hold such certificate(s) and Stock Powers in escrow and to take all such actions
and to effectuate all such transfers and/or releases of such Shares as are in
accordance with the terms of this Agreement. Purchaser and the Company agree
that Escrow Holder will not be liable to any party to this Exercise Agreement
(or to any other party) for any actions or omissions unless Escrow Holder is
grossly negligent or intentionally fraudulent in carrying out the duties of
Escrow Holder under this Exercise Agreement. Escrow Holder may rely upon any
letter, notice or other document executed by any signature purported to be
genuine and may rely on the advice of counsel and obey any order of any court
with respect to the transactions contemplated by this Agreement. The Shares will
be released from escrow upon termination of the Right of First Refusal.

        11.    RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

             11.1 LEGENDS. Purchaser understands and agrees that the Company
will place the legends set forth below or similar legends on any stock
certificate(s) evidencing the Shares, together with any other legends that may
be required by state or federal securities laws, the Company's Articles of
Incorporation or Bylaws, any other agreement between Purchaser and the Company
or any agreement between Purchaser and any third party:

             THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
             THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
             UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE
             SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT
             BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND
             APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
             EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE
             REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN
             INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY
             REQUIRE AN OPINION 



<PAGE>   29

             OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO
             THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE
             WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

             THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
             RESTRICTIONS ON PUBLIC RESALE, TRANSFER, AND RIGHT OF FIRST REFUSAL
             OPTIONS HELD BY THE ISSUER AND/OR ITS ASSIGNEE(S) AS SET FORTH IN A
             STOCK OPTION EXERCISE AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL
             HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE
             PRINCIPAL OFFICE OF THE ISSUER. SUCH PUBLIC SALE AND TRANSFER
             RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES
             OF THESE SHARES.

             The California Commissioner of Corporations may require that the
following legend also be placed upon the share certificate(s) evidencing
ownership of the Shares:

             IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS SECURITY,
             OR ANY INTEREST THEREIN, OR TO RECEIVE ANY CONSIDERATION THEREFOR,
             WITHOUT THE PRIOR WRITTEN CONSENT OF THE COMMISSIONER OF
             CORPORATIONS OF THE STATE OF CALIFORNIA, EXCEPT AS PERMITTED IN THE
             COMMISSIONER'S RULES.

             11.2 STOP-TRANSFER INSTRUCTIONS. Purchaser agrees that, to ensure
compliance with the restrictions imposed by this Agreement, the Company may
issue appropriate "stop-transfer" instructions to its transfer agent, if any,
and if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

             11.3 REFUSAL TO TRANSFER. The Company will not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares, or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares have been so transferred.

        12. TAX CONSEQUENCES. PURCHASER UNDERSTANDS THAT PURCHASER MAY SUFFER
ADVERSE TAX CONSEQUENCES AS A RESULT OF PURCHASER'S PURCHASE OR DISPOSITION OF
THE SHARES. PURCHASER REPRESENTS THAT PURCHASER HAS CONSULTED WITH ANY TAX
ADVISER PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR DISPOSITION
OF THE SHARES AND THAT PURCHASER IS NOT RELYING ON THE COMPANY FOR ANY TAX
ADVICE. Set forth below is a brief summary as of the date of this Exercise
Agreement of some of the federal and California tax consequences of exercise of
the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS 




<PAGE>   30

AND REGULATIONS ARE SUBJECT TO CHANGE. PURCHASER SHOULD CONSULT A TAX ADVISER
BEFORE EXECUTING THIS OPTION OR DISPOSING OF THE SHARES.

             12.1 EXERCISE OF INCENTIVE STOCK OPTION. If the Option qualifies as
an incentive stock option, there will be no regular federal income tax liability
or California income tax liability upon the exercise of the Option, although the
excess, if any, of the fair market value of the Shares on the date of exercise
over the Purchase Price Per Share will be treated as a tax preference item for
federal income tax purposes and may subject Purchaser to the alternative minimum
tax in the year of exercise.

             12.2 EXERCISE OF NONQUALIFIED STOCK OPTION. If the Option does not
qualify as an incentive stock option, there may be a regular federal income tax
liability and a California income tax liability upon the exercise of the Option.
Purchaser will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the fair market value
of the Shares on the date of exercise over the Purchase Price Per Share. The
Company will be required to withhold from Purchaser's compensation or collect
from Purchaser and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise.

             12.3 DISPOSITION OF SHARES. If the Shares are held for more than
twelve (12) months after the date of the transfer of the Shares pursuant to the
exercise of the Option and, in the case of an ISO, are disposed of more than two
years after the Option Date of Grant, any gain realized on disposition of the
Shares will be treated as long term capital gain for federal and California
income tax purposes. If Shares purchased under an ISO are disposed of within the
applicable one year or two year period, 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 fair market value of the Shares on the date
of exercise over the Purchase Price Per Share. The Company may be required to
withhold from Purchaser's compensation or collect from Purchaser and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income at the time of exercise.

        13. COMPLIANCE WITH LAWS AND REGULATIONS. The issuance and transfer of
the Shares will be subject to and conditioned upon compliance by the Company and
Purchaser with all applicable state and federal laws and regulations and with
all applicable requirements of any stock exchange or automated quotation system
on which the Company's Common Stock may be listed or quoted at the time of such
issuance or transfer.

        14. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights
under this Agreement, including its rights to repurchase Shares under the Right
of First Refusal. This Agreement shall be binding upon and inure to the benefit
of the successors and assigns of the Company. Subject to the restrictions on
transfer herein set forth, this Agreement will be binding upon Purchaser and
Purchaser's heirs, executors, administrators, legal representatives, successors
and assigns.

        15. GOVERNING LAW; SEVERABILITY. This Agreement shall be governed by and
construed in accordance with the internal laws of the State of California as
such laws are applied 



<PAGE>   31

to agreements between California residents entered into and to be performed
entirely within California. If any provision of this Agreement is determined by
a court of law to be illegal or unenforceable, then such provision will be
enforced to the maximum extent possible and the other provisions will remain
fully effective and enforceable.

        16. NOTICES. Any notice required to be given or delivered to the Company
shall be in writing and addressed to the Corporate Secretary of the Company at
its principal corporate offices. Any notice required to be given or delivered to
Purchaser shall be in writing and addressed to Purchaser at the address
indicated above or to such other address as Purchaser may designate in writing
from time to time to the Company. All notices shall be deemed effectively given
upon personal delivery, three (3) days after deposit in the United States mail
by certified or registered mail (return receipt requested), one (1) business day
after its deposit with any return receipt express courier (prepaid), or one (1)
business day after transmission by rapifax or telecopier.

        17. FURTHER INSTRUMENTS. The parties agree to execute such further
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Agreement.

        18. HEADINGS. The captions and headings of this Agreement are included
for ease of reference only and will be disregarded in interpreting or construing
this Agreement. All references herein to Sections will refer to Sections of this
Agreement.

        19. ENTIRE AGREEMENT. The Plan, the Stock Option Agreement and this
Exercise Agreement, together with all its Exhibits, constitute the entire
agreement and understanding of the parties with respect to the subject matter of
this Agreement, and supersede all prior understandings and agreements, whether
oral or written, between the parties hereto with respect to the specific subject
matter hereof.
