        2.     EXERCISE PERIOD.

               2.1    Exercise Period of Option. Provided Participant continues
to provide services to the Company, the Option will become vested and
exercisable as to portions of the Shares as follows: (i) this Option shall not
vest nor be exercisable with respect to any of the Shares until the First
Vesting Date set forth on the first page of this Agreement (the "FIRST VESTING
DATE"); (ii) on the First Vesting Date the Option will become vested and
exercisable as to twelve and one-half percent (12.5 %) of the Shares; and (iii)
thereafter at the end of each full succeeding month after the First Vesting
Date, the Option will become vested and exercisable as to an additional 2.08333%
of the Shares until the Shares are vested with respect to one hundred percent
(100%) of the Shares. If application of the vesting percentage causes a
fractional share, such share shall be rounded down to the nearest whole share
for each month except for the last month in such vesting period, at the end of
which last month this Option shall become exercisable for the full remainder of
the Shares.

               2.2    Vesting of Options. Shares that are vested pursuant to the
schedule set forth in Section 2.1 are "VESTED SHARES." Shares that are not
vested pursuant to the schedule set forth in Section 2.1 are "UNVESTED SHARES."

               2.3    Expiration. The Option shall expire on the Expiration Date
set forth above or earlier as provided in Section 3 below or pursuant to the
Plan.

        3.     TERMINATION.

               3.1    Termination for Any Reason Except Death, Disability or
Cause. If Participant is Terminated for any reason, except death, Disability or
for Cause, 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 (or Participant dies
within three (3) months of Termination when Termination is for any reason other
than Participant's Disability or for Cause), 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. Any exercise beyond (i) three (3) months after the Termination Date when
the Termination is for any reason other than the Participant's death or
disability, within the meaning of Section 22(e)(3) of the Code; or (ii) twelve
(12) months after the Termination Date when the termination is for Participant's
disability, within the meaning of Section 22(e)(3) of the Code, is deemed to be
an NQSO.

               3.3    Termination for Cause. If Participant is Terminated for
Cause, then the Option will expire on Participant's Termination Date, or at such
later time and on such conditions as are determined by the Committee.

               3.4    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

                                       2
<PAGE>   3

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 or incapacity,
Participant's executor, administrator, heir or legatee, as the case may be) must
deliver to the Company an executed stock option exercise agreement in the form
attached hereto as Exhibit A, or in such other form as may be approved by the
Committee from time to time (the "EXERCISE AGREEMENT"), which shall set forth,
inter alia, (i) Participant's election to exercise the Option, (ii) the number
of Shares being purchased, (iii) any restrictions imposed on the Shares and (iv)
any representations, warranties and agreements regarding Participant's
investment intent and access to information as 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 verifying that such person has the legal 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 one hundred (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)    provided that a public market for the Company's stock exists: (i)
               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 sufficient to pay for the total
               Exercise Price and whereby the NASD Dealer irrevocably commits
               upon receipt of such Shares to forward the total Exercise Price
               directly to the Company, or (ii) 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
               total Exercise Price, and whereby the NASD Dealer irrevocably
               commits upon receipt of such Shares to forward the total Exercise
               Price directly to the Company; or

        (c)    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

                                       3
<PAGE>   4

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 the minimum number of Shares with a Fair
Market Value equal to the minimum amount of taxes required to be withheld; but
in no event will the Company withhold Shares if such withholding would result in
adverse accounting consequences to the Company. 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 (i) the date two (2)
years after the Date of Grant, and (ii) the date one (1) 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 Plan and this Agreement
are intended to comply with Section 25102(o) of the California Corporations Code
and any regulations relating thereto. Any provision of this Agreement which is
inconsistent with Section 25102(o) or any regulations relating thereto shall,
without further act or amendment by the Company or the Board, be reformed to
comply with the requirements of Section 25102(o) and any regulations relating
thereto. 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 SEC, 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 or in
the event of Participant's incapacity, by Participant's legal representative.
The terms of the Option shall be binding upon the executors, administrators,
successors and assigns of Participant.

        8.     COMPANY'S RIGHT OF FIRST REFUSAL. Before any Vested Shares held
by Participant or any transferee of such Vested Shares 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 Vested Shares to be sold or transferred on the terms and
conditions set forth in the Exercise Agreement (the "RIGHT OF FIRST REFUSAL").
The Company's Right of First Refusal will terminate when the Company's
securities become publicly traded.

        9.     TAX CONSEQUENCES. Set forth below is a brief summary as of the
Effective Date of the Plan 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.

               9.1    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 alternative minimum tax purposes and may subject the
Participant to the alternative minimum tax in the year of exercise.

               9.2    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 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.

               9.3    Disposition of Shares. The following tax consequences may
apply upon disposition of the Shares.

                      (a)    Incentive Stock Options. 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 an ISO and are disposed of more than two (2) 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 (1) year or two (2) 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.

                      (b)    Nonqualified Stock Options. 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 an NQSO, any gain realized on disposition of the
Shares will be treated as long term capital gain.

                      (c)    Withholding. The Company may be required to
withhold from the Participant's compensation or collect from the Participant and
pay to the applicable taxing authorities an amount equal to a percentage of this
compensation income.

        10.    PRIVILEGES OF STOCK OWNERSHIP. Participant shall not have any of
the rights of a stockholder with respect to any Shares until the Shares are
issued to Participant.

        11.    INTERPRETATION. Any dispute regarding the interpretation of this
Agreement shall be submitted by Participant or the Company to the Committee for
review. The

                                       5
<PAGE>   6

resolution of such a dispute by the Committee shall be final and binding on the
Company and Participant.

        12.    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.

        13.    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: (i) personal
delivery; (ii) three (3) days after deposit in the United States mail by
certified or registered mail (return receipt requested); (iii) one (1) business
day after deposit with any return receipt express courier (prepaid); or (iv) one
(1) business day after transmission by facsimile, rapifax or telecopier.

        14.    SUCCESSORS AND ASSIGNS. The Company may assign any of its rights
under this Agreement including its rights to purchase 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 set forth herein, this Agreement shall be binding upon Participant and
Participant's heirs, executors, administrators, legal representatives,
successors and assigns.

        15.    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. 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.    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 triplicate by its duly authorized representative and Participant has executed
this Agreement in triplicate, effective as of the Date of Grant.

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.

               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.

               3.6    Financial Statements. Purchaser has received or otherwise
had access to financial statements of the Company annually during the period
that the Option was outstanding.

        4.     COMPLIANCE WITH SECURITIES LAWS.

               4.1    Compliance with U.S. Federal Securities Laws. Purchaser
understands and acknowledges that the Shares have not been registered with the
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 exemption provided by SEC Rule 701.

               4.2    Compliance with California Securities Laws. THE PLAN, THE
STOCK OPTION AGREEMENT, AND THIS EXERCISE AGREEMENT ARE INTENDED TO COMPLY WITH
SECTION 25102(O) OF THE CALIFORNIA CORPORATIONS CODE AND ANY RULES (INCLUDING
COMMISSIONER RULES, IF APPLICABLE) OR

                                       11
<PAGE>   12

REGULATIONS PROMULGATED THEREUNDER BY THE CALIFORNIA DEPARTMENT OF CORPORATIONS
(THE "REGULATIONS"). ANY PROVISION OF THIS EXERCISE AGREEMENT WHICH IS
INCONSISTENT WITH SECTION 25102(O) SHALL, WITHOUT FURTHER ACT OR AMENDMENT BY
THE COMPANY OR THE BOARD, BE REFORMED TO COMPLY WITH THE REQUIREMENTS OF SECTION
25102(O). 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 Shares be held for a minimum of one
(1) year, and in certain cases two (2) 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 are issued pursuant to SEC Rule
701 promulgated under the Securities Act and may become freely tradeable by
non-affiliates (under limited conditions regarding the method of sale) of the
Company ninety (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.

<PAGE>   13

        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 Exercise 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 actions 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) have 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
Regulations referred to in Section 4.2 hereof.

               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 described below, except as permitted by this Exercise
Agreement.

               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 Exercise 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 hereof,
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 one hundred eighty (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.
Purchaser further agrees to enter into any agreement reasonably required by the
underwriters to implement the foregoing.

                                       13
<PAGE>   14

        8.     COMPANY'S RIGHT OF FIRST REFUSAL. Before any Vested Shares held
by Purchaser or any transferee of such Vested Shares (either 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) will have a right of first refusal to purchase the Vested 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 will 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 and address of each proposed purchaser or other transferee
(the "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 acknowledges this Notice is an offer
to sell the Offered Shares to the Company and/or its assignee(s) pursuant to the
Company's Right of First Refusal at the Offered Price as provided for in this
Exercise Agreement.

               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
(or, with the consent of the Holder, less than all) 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, provided that if the
Offered Price consists of no legal consideration (as, for example, in the case
of a transfer by gift) the purchase price will be the fair market value of the
Offered Shares as determined in good faith by the Company's Board of Directors.
If the Offered Price includes consideration other than cash, then the value of
the non-cash consideration, as determined in good faith by the Company's Board
of Directors, will conclusively be deemed to be the cash equivalent value of
such non-cash consideration.

               8.4    Payment. Payment of the purchase price for the 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 owed by 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 each
Proposed Transferee at the Offered Price or at a higher price, provided that (i)
such sale or other transfer is consummated within one hundred twenty (120) days
after the date of the Notice, (ii) any such sale or other transfer is effected
in compliance with all applicable securities laws, and (iii) each 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 each Proposed
Transferee within such one hundred twenty (120) day period, then a new Notice
must

                                       14
<PAGE>   15

be given to the Company pursuant to which 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 Vested Shares will be exempt from
the Right of First Refusal: (i) the transfer of any or all of the Vested 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 signed by such transferee or
recipient and satisfactory to the Company that the provisions of this Section
will continue to apply to the transferred Vested Shares in the hands of such
transferee or other recipient; (ii) any transfer of Vested 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 Vested 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 unless the stock of such surviving corporation
is publicly traded); or (iii) any transfer of Vested 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, child, adopted child, grandchild or adopted
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).

               8.8    Encumbrances on Vested Shares. Purchaser may grant a lien
or security interest in, or pledge, hypothecate or encumber Vested Shares only
if each party to whom such lien or security interest is granted, or to whom such
pledge, hypothecation or other encumbrance is made, agrees in a writing
satisfactory to the Company that: (i) such lien, security interest, pledge,
hypothecation or encumbrance will not apply to such Vested Shares after they are
acquired by the Company and/or its assignees under this Section; and (ii) the
provisions of this Section will continue to apply to such Vested Shares in the
hands of such party and any transferee of such party. Purchaser may not grant a
lien or security interest in, or pledge, hypothecate or encumber, any Unvested
Shares.

        9.     RIGHTS AS A 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 Shares
are issued to Purchaser 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, other than 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.

                                       15
<PAGE>   16

        10.    ESCROW. As security for Purchaser's faithful performance of this
Exercise 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 (the "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 Exercise 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 with 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 Exercise
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 U.S. Federal securities laws, the Company's Certificate
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 SECURITIES
               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 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 AND TRANSFER, INCLUDING THE 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 INCLUDING THE
               RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE
               SHARES.

                                       16
<PAGE>   17

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
               MARKET STANDOFF RESTRICTION AS SET FORTH IN A CERTAIN 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. AS A RESULT OF SUCH AGREEMENT,
               THESE SHARES MAY NOT BE TRADED PRIOR TO 180 DAYS AFTER THE
               EFFECTIVE DATE OF THE INITIAL PUBLIC OFFERING OF THE COMMON STOCK
               OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES
               OF THESE SHARES.

               11.2   Stop-Transfer Instructions. Purchaser agrees that, to
ensure compliance with the restrictions imposed by this Exercise 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 Exercise 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: (i) THAT PURCHASER HAS CONSULTED WITH ANY TAX
ADVISER THAT PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR
DISPOSITION OF THE SHARES AND (ii) THAT PURCHASER IS NOT RELYING ON THE COMPANY
FOR ANY TAX ADVICE. Set forth below is a brief summary as of the date the Plan
was adopted by the Board of some of the U.S. 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. PURCHASER SHOULD CONSULT HIS OR HER OWN TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

               12.1   Exercise of Incentive Stock Option. If the Option
qualifies as an ISO, there will be no regular U.S. 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 Exercise Price will be treated as a tax preference item for U.S.
Federal alternative minimum 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 ISO, there may be a regular U.S. 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 Exercise Price. 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.

                                       17
<PAGE>   18

               12.3   Disposition of Shares. The following tax consequences may
apply upon disposition of the Shares.

                      (a)    Incentive Stock Options. 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 an ISO and are disposed of more than two (2) 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 (1) year or two (2) 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.

                      (b)    Nonqualified Stock Options. 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 an NQSO, any gain realized on disposition of the
Shares will be treated as long term capital gain.

                      (c)    Withholding. The Company may be required to
withhold from the Purchaser's compensation or collect from the Purchaser and pay
to the applicable taxing authorities an amount equal to a percentage of this
compensation income.

        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 U.S. 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 Exercise Agreement, including its rights to purchase Shares under the
Right of First Refusal. This Exercise 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 Exercise Agreement will be
binding upon Purchaser and Purchaser's heirs, executors, administrators, legal
representatives, successors and assigns.

        15.    GOVERNING LAW; SEVERABILITY. This Exercise Agreement shall be
governed by and construed in accordance with the internal 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. If any provision of
this Exercise 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, (i) three (3) days after deposit in
the United States mail by certified or registered mail (return receipt
requested), (ii) one (1) business day after its deposit with any return receipt
express courier (prepaid), or (iii) one (1) business day after transmission by
rapifax or telecopier.

instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Exercise Agreement.

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

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

TYPE OF STOCK OPTION:        NONQUALIFIED STOCK OPTION

        1.     GRANT OF OPTION. The Company hereby grants to Participant a
nonqualified option (this "OPTION") to purchase up to the total number of shares
of Common Stock, $0.00001 par value, of the Company set forth above as Total
Option Shares (the "Shares") at the Exercise Price Per Share set forth above
(the "EXERCISE PRICE"), subject to all of the terms and conditions of this
Agreement and the Plan.

        2.     EXERCISE PERIOD.

               2.1    Exercise Period of Option. Provided Participant continues
to provide services to the Company or a Parent, Subsidiary or Affiliate of the
Company, this Option will become vested and exercisable as to portions of the
Shares as follows: (i) this Option shall not vest nor be exercisable with
respect to any of the Shares until the First Vesting Date set forth on the first
page of this Agreement (the "FIRST VESTING DATE"); (ii) on the First Vesting
Date the Option will become

                                       27
<PAGE>   28

vested and exercisable as to twenty-five percent (25%) of the Shares and (iii)
thereafter on each successive anniversary of the First Vesting Date, the Option
will become vested and exercisable as to an additional twenty-five percent (25%)
of the Shares until the Shares are vested with respect to one hundred percent
(100%) of the Shares. If application of the vesting percentage causes a
fractional share, such share shall be rounded down to the nearest whole share
for each year except for the last year in such vesting period, at the end of
which last year this Option shall become exercisable for the full remainder of
the Shares.

               2.2    Vesting of Options. Shares that are vested pursuant to the
schedule set forth in Section 2.1 are "VESTED SHARES." Shares that are not
vested pursuant to the schedule set forth in Section 2.1 are "UNVESTED SHARES."

               2.3    Expiration. This Option shall expire on the Expiration
Date set forth above or earlier as provided in Section 3 below or pursuant to
the Plan.

        3.     TERMINATION.

               3.1    Termination for Any Reason Except Death, Disability or
Cause. If Participant is Terminated for any reason, except death, Disability or
for Cause, 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 (or Participant dies
within three (3) months of Termination when Termination is for any reason other
than Participant's Disability or for Cause), 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. Any exercise beyond (i) three (3) months after the Termination Date when
the Termination is for any reason other than the Participant's death or
disability, within the meaning of Section 22(e)(3) of the Code; or (ii) twelve
(12) months after the Termination Date when the termination is for Participant's
disability, within the meaning of Section 22(e)(3) of the Code, is deemed to be
an NQSO.

               3.3    Termination for Cause. If Participant is Terminated for
Cause, then the Option will expire on Participant's Termination Date, or at such
later time and on such conditions as are determined by the Committee.

               3.4    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 or incapacity,
Participant's

                                       28
<PAGE>   29

executor, administrator, heir or legatee, as the case may be) must deliver to
the Company an executed stock option exercise agreement in the form attached
hereto as Exhibit A, or in such other form as may be approved by the Committee
from time to time (the "EXERCISE AGREEMENT"), which shall set forth, inter alia,
(i) Participant's election to exercise the Option, (ii) the number of Shares
being purchased, (iii) any restrictions imposed on the Shares and (iv) any
representations, warranties and agreements regarding Participant's investment
intent and access to information as 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 verifying that such person has the legal 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 one hundred (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)    provided that a public market for the Company's stock exists: (i)
               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 sufficient to pay for the total
               Exercise Price and whereby the NASD Dealer irrevocably commits
               upon receipt of such Shares to forward the total Exercise Price
               directly to the Company, or (ii) 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
               total Exercise Price, and whereby the NASD Dealer irrevocably
               commits upon receipt of such Shares to forward the total Exercise
               Price directly to the Company; or

        (c)    by any combination of the foregoing.

               4.4    Tax Withholding. Prior to the issuance of Shares upon each
exercise of the Option, Participant must pay or provide for any applicable
federal, state and local 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 the minimum number
of Shares with a Fair Market Value equal to the minimum amount of taxes required
to be withheld; but in no event will the Company withhold Shares if such
withholding would result in adverse accounting consequences to the Company. 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.

                                       29
<PAGE>   30

               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.     COMPLIANCE WITH LAWS AND REGULATIONS. The Plan and this Agreement
are intended to comply with Section 25102(o) of the California Corporations Code
and any regulations relating thereto. Any provision of this Agreement which is
inconsistent with Section 25102(o) or any regulations relating thereto shall,
without further act or amendment by the Company or the Board, be reformed to
comply with the requirements of Section 25102(o) and any regulations relating
thereto. 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 SEC, any state securities commission or any stock exchange to
effect such compliance.

        6.     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 or in
the event of Participant's incapacity, by Participant's legal representative.
The terms of the Option shall be binding upon the executors, administrators,
successors and assigns of Participant.

        7.     COMPANY'S RIGHT OF FIRST REFUSAL. Before any Vested Shares held
by Participant or any transferee of such Vested Shares 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 Vested Shares to be sold or transferred on the terms and
conditions set forth in the Exercise Agreement (the "RIGHT OF FIRST REFUSAL").
The Company's Right of First Refusal will terminate when the Company's
securities become publicly traded.

        8.     TAX CONSEQUENCES. Set forth below is a brief summary as of the
Effective Date of the Plan 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 Nonqualified Stock Option. 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 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.

                                       30
<PAGE>   31

               8.2    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 a nonqualified stock option, any gain realized on disposition of
the Shares will be treated as long term capital gain.

        9.     PRIVILEGES OF STOCK OWNERSHIP. Participant shall not have any of
the rights of a stockholder with respect to any Shares until the Shares are
issued to Participant.

        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: (i) personal
delivery; (ii) three (3) days after deposit in the United States mail by
certified or registered mail (return receipt requested); (iii) one (1) business
day after deposit with any return receipt express courier (prepaid); or (iv) one
(1) business day after transmission by facsimile, rapifax or telecopier.

        13.    SUCCESSORS AND ASSIGNS. The Company may assign any of its rights
under this Agreement including its rights to purchase 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 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. 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.

        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 triplicate by its duly authorized representative and Participant has executed

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

                                       35
<PAGE>   36

               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. 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.

               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.

               3.6    Financial Statements. Purchaser has received or otherwise
had access to financial statements of the Company annually during the period
that the Option was outstanding.

        4.     COMPLIANCE WITH SECURITIES LAWS.

               4.1    Compliance with U.S. Federal Securities Laws. Purchaser
understands and acknowledges that the Shares have not been registered with the
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 exemption provided by SEC Rule 701.

               4.2    Compliance with California Securities Laws. THE PLAN, THE
STOCK OPTION AGREEMENT, AND THIS EXERCISE AGREEMENT ARE INTENDED TO COMPLY WITH
SECTION 25102(o) OF THE CALIFORNIA CORPORATIONS CODE AND ANY RULES (INCLUDING
COMMISSIONER RULES, IF APPLICABLE) OR

                                       36
<PAGE>   37

REGULATIONS PROMULGATED THEREUNDER BY THE CALIFORNIA DEPARTMENT OF CORPORATIONS
(THE "REGULATIONS"). ANY PROVISION OF THIS EXERCISE AGREEMENT WHICH IS
INCONSISTENT WITH SECTION 25102(O) SHALL, WITHOUT FURTHER ACT OR AMENDMENT BY
THE COMPANY OR THE BOARD, BE REFORMED TO COMPLY WITH THE REQUIREMENTS OF SECTION
25102(O). 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 for such
transfer. 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 Shares be held for a minimum of one
(1) year, and in certain cases two (2) 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 are issued pursuant to SEC Rule
701 promulgated under the Securities Act and may become freely tradeable by
non-affiliates (under limited conditions regarding the method of sale) of the
Company ninety (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.

        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 Exercise 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 actions 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) have 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
Regulations referred to in Section 4.2 hereof.

               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 described below, except as permitted by this Exercise
Agreement.

               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 Exercise 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 hereof,
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 one hundred eighty (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.
Purchaser further agrees to enter into any agreement reasonably required by the
underwriters to implement the foregoing.

                                       38
<PAGE>   39

        8.     COMPANY'S RIGHT OF FIRST REFUSAL. Before any Vested Shares held
by Purchaser or any transferee of such Vested Shares (either 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) will have a right of first refusal to purchase the Vested 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 will 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 and address of each proposed purchaser or other transferee
(the "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 acknowledges this Notice is an offer
to sell the Offered Shares to the Company and/or its assignee(s) pursuant to the
Company's Right of First Refusal at the Offered Price as provided for in this
Exercise Agreement.

               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
(or, with the consent of the Holder, less than all) 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, provided that if the
Offered Price consists of no legal consideration (as, for example, in the case
of a transfer by gift) the purchase price will be the fair market value of the
Offered Shares as determined in good faith by the Company's Board of Directors.
If the Offered Price includes consideration other than cash, then the value of
the non-cash consideration, as determined in good faith by the Company's Board
of Directors, will conclusively be deemed to be the cash equivalent value of
such non-cash consideration.

               8.4    Payment. Payment of the purchase price for the 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 owed by 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 each
Proposed Transferee at the Offered Price or at a higher price, provided that (i)
such sale or other transfer is consummated within one hundred twenty (120) days
after the date of the Notice, (ii) any such sale or other transfer is effected
in compliance with all applicable securities laws, and (iii) each 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 each Proposed
Transferee within such one hundred twenty (120) day period, then a new Notice
must

                                       39
<PAGE>   40

be given to the Company pursuant to which 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 Vested Shares will be exempt from
the Right of First Refusal: (i) the transfer of any or all of the Vested 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 signed by such transferee or
recipient and satisfactory to the Company that the provisions of this Section
will continue to apply to the transferred Vested Shares in the hands of such
transferee or other recipient; (ii) any transfer of Vested 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 Vested 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 unless the stock of such surviving corporation
is publicly traded) or unless the Shares or securities into which the Shares are
converted or exchanged in such merger or consolidation are registered under the
Securities Act; or (iii) any transfer of Vested 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, child, adopted child, grandchild or adopted
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).

               8.8    Encumbrances on Vested Shares. Purchaser may grant a lien
or security interest in, or pledge, hypothecate or encumber Vested Shares only
if each party to whom such lien or security interest is granted, or to whom such
pledge, hypothecation or other encumbrance is made, agrees in a writing
satisfactory to the Company that: (i) such lien, security interest, pledge,
hypothecation or encumbrance will not apply to such Vested Shares after they are
acquired by the Company and/or its assignees under this Section; and (ii) the
provisions of this Section will continue to apply to such Vested Shares in the
hands of such party and any transferee of such party. Purchaser may not grant a
lien or security interest in, or pledge, hypothecate or encumber, any Unvested
Shares.

        9.     RIGHTS AS A 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 Shares
are issued to Purchaser 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, other than 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.

                                       40
<PAGE>   41

        10.    ESCROW. As security for Purchaser's faithful performance of this
Exercise 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 (the "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 Exercise 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 with 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 Exercise
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 U.S. Federal securities laws, the Company's Certificate
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 SECURITIES
               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 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 AND TRANSFER, INCLUDING THE 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 INCLUDING THE
               RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE
               SHARES.

                                       41
<PAGE>   42

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
               MARKET STANDOFF RESTRICTION AS SET FORTH IN A CERTAIN 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. AS A RESULT OF SUCH AGREEMENT,
               THESE SHARES MAY NOT BE TRADED PRIOR TO 180 DAYS AFTER THE
               EFFECTIVE DATE OF THE INITIAL PUBLIC OFFERING OF THE COMMON STOCK
               OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES
               OF THESE SHARES.

               11.2   Stop-Transfer Instructions. Purchaser agrees that, to
ensure compliance with the restrictions imposed by this Exercise 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 Exercise 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: (i) THAT PURCHASER HAS CONSULTED WITH ANY TAX
ADVISER THAT PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR
DISPOSITION OF THE SHARES AND (ii) THAT PURCHASER IS NOT RELYING ON THE COMPANY
FOR ANY TAX ADVICE. Set forth below is a brief summary as of the date the Plan
was adopted by the Board of some of the U.S. 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. PURCHASER SHOULD CONSULT HIS OR HER OWN TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

               12.1   Exercise of Nonqualified Stock Option. There may be a
regular U.S. 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
Exercise Price. 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.

               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 a nonqualified stock option, any gain realized on disposition of
the Shares will be treated as long term capital gain.

        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

                                       42
<PAGE>   43

all applicable state and U.S. 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 Exercise Agreement, including its rights to purchase Shares under the
Right of First Refusal. This Exercise Agreement shall be binding upon and inure

                                    eHNC INC.

                      1999 EXECUTIVE EQUITY INCENTIVE PLAN

                        AS ADOPTED ON SEPTEMBER 27, 1999

        1.     PURPOSE. The purpose of this 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 and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options and Restricted Stock. Capitalized
terms not defined in the text are defined in Section 22 hereof.

        2.     SHARES SUBJECT TO THE PLAN.

               2.1    Number of Shares Available. Subject to Sections 2.2 and 17
hereof, the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 1,955,000 Shares. Subject to Sections 2.2, 5.10
and 17 hereof, Shares subject to Awards previously granted will again be
available for grant and issuance in connection with future Awards under this
Plan to the extent such Shares: (i) cease to be subject to issuance upon
exercise of an Option, other than due to exercise of such Option; (ii) are
subject to an Award granted hereunder but the Shares subject to such Award are
forfeited or repurchased by the Company at the original issue price; or (iii)
are subject to an Award that otherwise terminates without Shares being issued.
At all times the Company will reserve and keep available a sufficient number of
Shares as will be required to satisfy the requirements of all Awards granted and
outstanding under this Plan.

               2.2    Adjustment of Shares. In the event that the number of
outstanding shares of the Company's Common Stock 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 (i) the number of Shares reserved for issuance under
this Plan, (ii) the Exercise Prices of and number of Shares subject to
outstanding Options and (iii) the Purchase Prices of and number of Shares
subject to other outstanding Awards will be proportionately adjusted, subject to
any required action by the Board or the stockholders of the Company and
compliance with applicable securities laws; provided, however, that fractions of
a Share will not be issued but will either be paid in cash at the Fair Market
Value of such fraction of a Share or will be rounded down to the nearest whole
Share, as determined by the Committee and provided, further, that the Exercise
Price of any Option may not be decreased to below the par value of the Shares.

        3.     ELIGIBILITY. The persons eligible to purchase Shares under this
Plan shall be such directors, officers and key employees of the Company or of
any Parent, Subsidiary or Affiliate of the Company who: (a) the Committee shall
select from time to time in its sole discretion and (b) the Committee determines
possess the qualifications necessary to purchase Common Stock from the Company
without registration or qualification of such sale under the 1933 Act, the
California Corporate Securities Law of 1968, as amended (the "CALIFORNIA LAW")

                                       1
<PAGE>   2

or applicable "blue sky" securities laws of other jurisdictions pursuant to the
exemptions from such registration and qualification requirements provided by
Section 4(2), Rule 701 and/or Regulation D under the 1933 Act, Section 25102(f)
of the California Law and available exemptions under such applicable blue sky
securities laws. ISOs (as defined in Section 5 hereof) 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. NQSOs (as defined in
Section 5 hereof) and Restricted Stock Awards may be granted to employees,
officers, directors and consultants of the Company or any Parent, Subsidiary or
Affiliate of the Company; provided such consultants 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 this Plan.

        4.     ADMINISTRATION.

               4.1    Committee Authority. This Plan will be administered by the
Committee or the Board if no Committee is created by the Board. Subject to the
general purposes, terms and conditions of this Plan, and to the direction of the
Board, the Committee will have full power to implement and carry out this Plan.
Without limitation, the Committee will have the authority to:

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

               (b)    prescribe, amend and rescind rules and regulations
                      relating to this Plan;

               (c)    approve persons to receive Awards;

               (d)    determine the form and terms of Awards;

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

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

               (g)    grant waivers of any conditions of this Plan or any Award;

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

               (i)    correct any defect, supply any omission, or reconcile any
                      inconsistency in this Plan, any Award, any Award
                      Agreement, any Exercise Agreement or any Restricted Stock
                      Purchase Agreement;

               (j)    determine whether an Award has been earned;

               (m)    make all other determinations necessary or advisable for
                      the administration of this Plan; and

               (n)    extend the vesting period beyond a Participant's
                      Termination Date.

               4.2    Committee Discretion. Unless in contravention of any
express terms of this Plan or Award, any determination made by the Committee
with respect to any Award will be

                                       2
<PAGE>   3

made in its sole discretion either (i) at the time of grant of the Award, or
(ii) subject to Section 5.9 hereof, at any later time. Any such determination
will be final and binding on the Company and on all persons having an interest
in any Award under this Plan. The Committee may delegate to one or more officers
of the Company the authority to grant an Award under this Plan, provided such
officer or officers are members of the Board.

        5.     OPTIONS. The Committee may grant Options to eligible persons
described in Section 3 hereof and will determine whether such Options will 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 this Plan
will be evidenced by an Award Agreement which will expressly identify the Option
as an ISO or an NQSO ("STOCK OPTION AGREEMENT"), and will be in such form and
contain such provisions (which need not be the same for each Participant) as the
Committee may from time to time approve, and which will comply with and be
subject to the terms and conditions of this Plan.

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

               5.3    Exercise Period. Options may be exercisable immediately
but subject to repurchase pursuant to Section 11 hereof or may be exercisable
within the times or upon the events determined by the Committee as set forth in
the Stock Option Agreement governing such Option; provided, however, that no
Option will be exercisable after the expiration of ten (10) years from the date
the Option is granted; and provided further that no ISO 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 of any Parent or
Subsidiary of the Company ("TEN PERCENT SHAREHOLDER") will be exercisable after
the expiration of five (5) years from the date the ISO is granted. The Committee
also may provide for Options to become exercisable at one time or from time to
time, periodically or otherwise, in such number of Shares or percentage of
Shares as the Committee determines. Subject to earlier termination of the Option
as provided herein, each Participant who is not an officer, director or
consultant of the Company or of a Parent or Subsidiary of the Company shall have
the right to exercise an Option granted hereunder at the rate of no less than
twenty percent (20%) per year over five (5) years from the date such Option is
granted.

               5.4    Exercise Price. The Exercise Price of an Option will be
determined by the Committee when the Option is granted and may not be less than
eighty-five percent (85%) of the Fair Market Value of the Shares on the date of
grant; provided that (i) the Exercise Price of an ISO will not be less than one
hundred percent (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 will not be less than one hundred ten percent (110%) of the Fair
Market Value of the Shares on the date of grant. Payment for the Shares
purchased must be made in accordance with Section 7 hereof.

                                       3
<PAGE>   4

               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). The Exercise Agreement will state
(i) the number of Shares being purchased, (ii) the restrictions imposed on the
Shares purchased under such Exercise Agreement, if any, and (iii) such
representations and agreements regarding Participant's investment intent and
access to information and other matters, if any, as may be required or desirable
by the Company to comply with applicable securities laws. Participant shall
execute and deliver to the Company the Exercise Agreement together with payment
in full of the Exercise Price, and any applicable taxes, for the number of
Shares being purchased.

               5.6    Termination. Subject to earlier termination pursuant to
Sections 17 and 18 hereof and unless otherwise determined by the Committee and
set forth in the Stock Option Agreement, exercise of an Option will be subject
to the following:

               (a)    If the Participant is Terminated for any reason other than
                      death, Disability or for Cause, then the Participant may
                      exercise such Participant's Options only to the extent
                      that such Options are exercisable upon the Termination
                      Date or as otherwise determined by the Committee. Such
                      Options must be exercised by the Participant, if at all,
                      as to all or some of the Vested Shares calculated as of
                      the Termination Date or such other date determined by the
                      Committee, within three (3) months after the Termination
                      Date (or within such shorter time period, not less than
                      thirty (30) days, or within such longer time period, not
                      exceeding five (5) years, after the Termination Date as
                      may be determined by the Committee, with any exercise
                      beyond three (3) months after the Termination Date deemed
                      to be an NQSO) but in any event, no later than the
                      expiration date of the Options.

               (b)    If the Participant is Terminated because of Participant's
                      death or Disability (or the Participant dies within three
                      (3) months after a Termination other than for Cause), then
                      Participant's Options may be exercised only to the extent
                      that such Options are exercisable by Participant on the
                      Termination Date or as otherwise determined by the
                      Committee. Such options must be exercised by Participant
                      (or Participant's legal representative or authorized
                      assignee), if at all, as to all or some of the Vested
                      Shares calculated as of the Termination Date or such other
                      date determined by the Committee, within twelve (12)
                      months after the Termination Date (or within such shorter
                      time period, not less than six (6) months, or within such
                      longer time period, not exceeding five (5) years, after
                      the Termination Date as may be determined by the
                      Committee, with any exercise beyond (i) three (3) months
                      after the Termination Date when the Termination is for any
                      reason other than the Participant's death or disability,
                      within the meaning of Section 22(e)(3) of the Code, or
                      (ii) twelve (12) months after the Termination Date when
                      the Termination is for Participant's disability, within
                      the meaning of Section 22(e)(3) of the Code, deemed to be
                      an NQSO) but in any event no later than the expiration
                      date of the Options.

               (c)    If the Participant is terminated for Cause, then
                      Participant's Options shall expire on such Participant's
                      Termination Date, or at such later time and on such
                      conditions as are determined by the Committee.

<PAGE>   5

               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
this Plan or under any other incentive stock option plan of the Company or any
Parent or Subsidiary of the Company) will not exceed One Hundred Thousand
Dollars ($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 One Hundred Thousand Dollars ($100,000), then the
Options for the first One Hundred Thousand Dollars ($100,000) worth of Shares to
become exercisable in such calendar year will be ISOs and the Options for the
amount in excess of One Hundred Thousand Dollars ($100,000) that become
exercisable in that calendar year will be NQSOs. In the event that the Code or
the regulations promulgated thereunder are amended after the Effective Date (as
defined in Section 18 hereof) to provide for a different limit on the Fair
Market Value of Shares permitted to be subject to ISOs, then such different
limit will be automatically incorporated herein and will 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 a Participant, impair any of such Participant's rights
under any Option previously granted. Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code. Subject to Section 5.10 hereof, the Committee may
reduce the Exercise Price of outstanding Options without the consent of
Participants 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 hereof for Options granted on the date the action is
taken to reduce the Exercise Price; provided, further, that the Exercise Price
will not be reduced below the par value of the Shares, if any.

               5.10   No Disqualification. Notwithstanding any other provision
in this Plan, no term of this Plan relating to ISOs will be interpreted, amended
or altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant, to disqualify any Participant's ISO
under Section 422 of the Code. In no event shall the total number of Shares
issued (counting each reissuance of a Share that was previously issued and then
forfeited or repurchased by the Company as a separate issuance) under the Plan
upon exercise of ISOs exceed 6,400,000 Shares (adjusted in proportion to any
adjustments under Section 2.2. hereof) over the term of the Plan.

        6.     RESTRICTED STOCK. A Restricted Stock Award is an offer by the
Company to sell to an eligible person Shares that are subject to certain
specified restrictions. The Committee will determine to whom an offer will be
made, the number of Shares the person may purchase, the Purchase Price, the
restrictions to which the Shares will 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 this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each

                                       5
<PAGE>   6

Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. The Restricted
Stock Award will 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 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 such thirty (30) days, then the offer will
terminate, unless otherwise determined by the Committee.

               6.2    Purchase Price. The Purchase Price of Shares sold pursuant
to a Restricted Stock Award will be determined by the Committee and will be at
least eighty-five percent (85%) of the Fair Market Value of the Shares on the
date the Restricted Stock Award is granted or at the time the purchase is
consummated, except in the case of a sale to a Ten Percent Shareholder, in which
case the Purchase Price will be one hundred percent (100%) of the Fair Market
Value on the date the Restricted Stock Award is granted or at the time the
purchase is consummated. Payment of the Purchase Price must be made in
accordance with Section 7 hereof.

               6.3    Restrictions. Restricted Stock Awards may be subject to
the restrictions set forth in Section 11 hereof or such other restrictions not
inconsistent with the California Corporations Code.

        7.     PAYMENT FOR SHARE PURCHASES.

               7.1    Payment. Payment for Shares purchased pursuant to this
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 owed to the
                      Participant;

               (b)    by surrender of shares that: (i) either (A) 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 (B) were obtained by
                      Participant in the public market and (ii) are clear of all
                      liens, claims, encumbrances or security interests;

               (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 or
                      directors of the Company will not be entitled to purchase
                      Shares with a promissory note unless the note is
                      adequately secured by collateral other than the Shares;
                      provided, further, that the portion of the Exercise Price
                      or Purchase Price, as the case may be, equal to the par
                      value of the Shares must be paid in cash or other legal
                      consideration permitted by Delaware General Corporation
                      Law;

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

                                       6
<PAGE>   7

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

                      (i)    through a "same day sale" commitment from the
                             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 sufficient to pay the
                             total Exercise Price, and whereby the NASD Dealer
                             irrevocably commits upon receipt of such Shares to
                             forward the total Exercise Price directly to the
                             Company; or

                      (ii)   through a "margin" commitment from the Participant
                             and an NASD Dealer whereby the 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 total Exercise
                             Price, and whereby the NASD Dealer irrevocably
                             commits upon receipt of such Shares to forward the
                             total Exercise Price directly to the Company; or

               (f)    by any combination of the foregoing.

               7.2    Loan Guarantees. The Committee may, in its sole
discretion, elect to assist the Participant in paying for Shares purchased under
this Plan by authorizing a guarantee by the Company of a third-party loan to the
Participant.

        8.     WITHHOLDING TAXES.

               8.1    Withholding Generally. Whenever Shares are to be issued in
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares. Whenever, under this Plan, payments
in satisfaction of Awards are to be made in cash by the Company, such payment
will be net of an amount sufficient to satisfy federal, state, and local
withholding tax requirements.

               8.2    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 minimum 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; but in no event will the Company withhold
Shares if such withholding would result in adverse accounting consequences to
the Company. All elections by a Participant to have Shares withheld for this
purpose will be made in accordance with the requirements established by the
Committee for such elections and be in writing in a form acceptable to the
Committee.

                                       7
<PAGE>   8

        9.     PRIVILEGES OF STOCK OWNERSHIP.

               9.1    Voting and Dividends. No Participant will have any of the
rights of a stockholder with respect to any Shares until the Shares are issued
to the Participant. After Shares are issued to the Participant, the Participant
will be a stockholder and have all the rights of a stockholder 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 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 will be subject to the same restrictions as the
Restricted Stock. The Participant will have no right to retain such stock
dividends or stock distributions with respect to Unvested Shares that are
repurchased pursuant to Section 11 hereof.

               9.2    Financial Statements. The Company will provide financial
statements to each Participant annually during the period such Participant has
Awards outstanding, or as otherwise required under Section 260.140.46 of Title
10 of the California Code of Regulations. Notwithstanding the foregoing, the
Company will not be required to provide such financial statements to
Participants when issuance is limited to key employees whose services in
connection with the Company assure them access to equivalent information.

        10.    TRANSFERABILITY. Awards granted under this Plan, and any interest
therein, will not be transferable or assignable by Participant, other than by
will or by the laws of descent and distribution, and may not be made subject to
execution, attachment or similar process. During the lifetime of the Participant
an Award will be exercisable only by the Participant or Participant's legal
representative and any elections with respect to an Award may be made only by
the Participant or Participant's legal representative.

        11.    RESTRICTIONS ON SHARES.

               11.1   Right of First Refusal. At the discretion of the
Committee, the Company may reserve to itself and/or its assignee(s) in the Award
Agreement a right of first refusal to purchase all Shares that a Participant (or
a subsequent transferee) may propose to transfer to a third party, provided that
such right of first refusal terminates upon the Company's initial public
offering of Common Stock pursuant to an effective registration statement filed
under the Securities Act.

               11.2   Right of Repurchase. At the discretion of the Committee,
the Company may reserve to itself and/or its assignee(s) in the Award Agreement
a right to repurchase Unvested Shares held by a Participant for cash and/or
cancellation of purchase money indebtedness owed to the Company by the
Participant following such Participant's Termination at any time within the
later of ninety (90) days after the Participant's Termination Date and the date
the Participant purchases Shares under the Plan at the Participant's Exercise
Price or Purchase Price, as the case may be, provided that, unless the
Participant is an officer, director or consultant of the Company or of a Parent
or Subsidiary of the Company, such right of repurchase lapses at the rate of no
less than twenty percent (20%) per year over five (5) years from: (a) the date
of grant of the Option or (b) in the case of Restricted Stock, the date the
Participant purchases the Shares.

                                       8
<PAGE>   9

        12.    CERTIFICATES. All certificates for Shares or other securities
delivered under this Plan will 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 or
quoted.

        13.    ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant's Shares set forth in Section 11 hereof, the Committee may require
the Participant to deposit all certificates representing Shares, 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. 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 this Plan will 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 will 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 will be required to
execute and deliver a written pledge agreement in such form as the Committee
will from time to time approve.

        14.    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 of Common
Stock of the Company (including Restricted Stock) or other consideration, based
on such terms and conditions as the Committee and the Participant may agree.

        15.    SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award will 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 or quoted, 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 this Plan, the Company will have no obligation to issue
or deliver certificates for Shares under this Plan prior to (i) obtaining any
approvals from governmental agencies that the Company determines are necessary
or advisable, and/or (ii) compliance with any exemption, 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 will be under no obligation to register the
Shares with the SEC or to effect compliance with the exemption, registration,
qualification or listing requirements of any state securities laws, stock
exchange or automated quotation system, and the Company will have no liability
for any inability or failure to do so.

        16.    NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award
granted under this Plan will 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

                                       9
<PAGE>   10

or Affiliate of the Company to terminate Participant's employment or other
relationship at any time, with or without Cause.

        17.    CORPORATE TRANSACTIONS.

               17.1   Assumption or Replacement of Awards by Successor or
Acquiring Company. In the event of (i) a dissolution or liquidation of the
Company, (ii) a merger or consolidation in which the Company is not the
surviving corporation, (iii) a merger in which the Company is the surviving
corporation but after which the stockholders of the Company immediately prior to
such merger (other than any stockholder which merges with the Company in such
merger, or which owns or controls another corporation which merges with the
Company in such merger) cease to own their shares or other equity interests in
the Company, or (iv) the sale of all or substantially all of the assets of the
Company, any or all outstanding Awards may be assumed, converted or replaced by
the successor or acquiring corporation (if any) with or into cash, options
and/or other securities or property, which assumption, conversion or replacement
will be binding on all Participants. In the alternative, the successor or
acquiring corporation may substitute equivalent Awards or provide substantially
similar consideration to Participants as was provided to stockholders in such
transactions (after taking into account the existing provisions of the Awards).
The successor or acquiring corporation may also substitute by issuing, in place
of outstanding Shares of the Company held by the Participant, substantially
similar shares or other property subject to repurchase restrictions and other
provisions no less favorable to the Participant than those which applied to such
outstanding Shares immediately prior to such transaction described in this
Section 17.1. In the event such successor or acquiring corporation (if any)
refuses to assume, convert, replace or substitute Awards, as provided above,
pursuant to a transaction described in this Section 17.1, then notwithstanding
any other provision in this Plan to the contrary, such Awards will expire upon
the consummation of such transaction at such time and on such conditions as the
Board will determine.

               17.2   Other Treatment of Awards. Subject to any greater rights
granted to Participants under the foregoing provisions of this Section 17, in
the event of the occurrence of any transaction described in Section 17.1 hereof,
any outstanding Awards will be treated as provided in the applicable agreement
or plan of merger, consolidation, dissolution, liquidation or sale of assets.

               17.3   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 (i) granting an Award under this Plan in substitution of
such other company's award or (ii) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan. Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant. In the event the Company assumes an award granted by
another company, the terms and conditions of such award will 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.

                                       10
<PAGE>   11

        18.    ADOPTION AND STOCKHOLDER APPROVAL. This Plan will become
effective on the date that it is adopted by the Board (the "EFFECTIVE DATE").
This Plan will be approved by the stockholders of the Company (excluding the
vote of Shares issued pursuant to this Plan), consistent with applicable laws,
within twelve (12) months before or after the Effective Date. Upon the Effective
Date, the Board may grant Awards pursuant to this Plan; provided, however, that:
(i) no Option may be exercised prior to initial stockholder approval of this
Plan; (ii) 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 stockholders of the Company; (iii) in the event that
initial stockholder approval is not obtained within the time period provided
herein, all Awards granted hereunder shall be canceled, any Shares issued
pursuant to any Award shall be canceled and any purchase of Shares issued
hereunder shall be rescinded; and (iv) Awards granted pursuant to an increase in
the number of Shares approved by the Board which increase is not timely approved
by stockholders shall be canceled, any Shares issued pursuant to any such Awards
shall be canceled, and any purchase of Shares subject to any such Award shall be
rescinded.

        19.    TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided
herein, this Plan will terminate ten (10) years from the Effective Date or, if
earlier, the date of stockholder approval. This Plan and all agreements
hereunder shall be governed by and construed in accordance with the laws of the
State of California.

        20.    AMENDMENT OR TERMINATION OF PLAN. Subject to Section 5.9 hereof,
the Board may at any time terminate or amend this Plan in any respect, including
without limitation amendment of any form of Award Agreement or instrument to be
executed pursuant to this Plan; provided, however, that the Board will not,
without the approval of the stockholders of the Company, amend this Plan in any
manner that requires such stockholder approval pursuant to the California
Corporations Code or the Code or the regulations promulgated thereunder as such
provisions apply to ISO plans.

        21.    NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by
the Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will 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 other equity awards otherwise than under this
Plan, and such arrangements may be either generally applicable or applicable
only in specific cases.
