<PAGE>   3

         (b) The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

               (1) To determine from time to time which of the persons eligible
under the Plan shall be granted Options; when and how each Option shall be
granted; whether an Option will be an Incentive Stock Option or a Nonstatutory
Stock Option; the provisions of each Option granted (which need not be
identical), including the time or times such Option may be exercised in whole or
in part; and the number of shares for which an Option shall be granted to each
such person.

               (2) To construe and interpret the Plan and Options granted under
it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Option Agreement, in a
manner and to the extent it shall deem necessary or expedient to make the Plan
fully effective.

               (3) To amend the Plan or an Option as provided in Section 11.

         (c) The Board may delegate administration of the Plan to a committee
composed of one or more members (the "Committee"), all of which may be
Non-Employee Directors. If administration is delegated to a Committee, the
Committee shall have, in connection with the administration of the Plan, the
powers theretofore possessed by the Board, (and references in this Plan to the
Board shall thereafter be to the Committee), subject, however, to such
resolutions, not inconsistent with the provisions of the Plan, as may be adopted
from time to time by the Board. The Board may abolish the Committee at any time
and revest in the Board the administration of the Plan.

     4. SHARES SUBJECT TO THE PLAN.

         (a) Subject to the provisions of Section 10 relating to adjustments
upon changes in stock, the stock that may be sold pursuant to Options shall not
exceed in the aggregate one million five hundred thousand (1,500,000) shares of
the Company's common stock. If any Option shall for any reason expire or
otherwise terminate, in whole or in part, without having been exercised in full,
the stock not purchased under such Option shall revert to and again become
available for issuance under the Plan.

         (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

     5. ELIGIBILITY.

         (a) Incentive Stock Options may be granted only to Employees.
Nonstatutory Stock Options may be granted only to Employees, Directors or
Consultants.

         (b) No person shall be eligible for the grant of an Option if, at the
time of grant, such person owns (or is deemed to own pursuant to Section 424(d)
of the Code) stock possessing more than ten percent (10%) of the total combined
voting power of all classes of stock of the Company or of any of its Affiliates
unless the exercise price of such Option is at least one hundred ten percent
(110%) of the Fair Market Value of such stock at the date of grant and the
Option is not exercisable after the expiration of five (5) years from the date
of grant.

     6. OPTION PROVISIONS.

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

                                       9
<PAGE>   4

         (a) Term. No Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.

         (b) Price. The exercise price of each Incentive Stock Option shall be
not less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted; the exercise price of
each Nonstatutory Stock Option shall be not less than eighty-five percent (85%)
of the Fair Market Value of the stock subject to the Option on the date the
Option is granted. Notwithstanding the foregoing, an Option (whether an
Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an
exercise price lower than that set forth in the preceding sentence if such
Option is granted pursuant to an assumption or substitution for another option
in a manner satisfying the provisions of Section 424(a) of the Code.

         (c) Consideration. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or the Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other common stock of the Company, (B)
according to a deferred payment or other arrangement (which may include, without
limiting the generality of the foregoing, the use of other common stock of the
Company) with the person to whom the Option is granted or to whom the Option is
transferred pursuant to subsection 6(d), or (C) in any other form of legal
consideration that may be acceptable to the Board.
         In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

         (d) Transferability. An Option shall not be transferable except by will
or by the laws of descent and distribution, and shall be exercisable during the
lifetime of the person to whom the Option is granted only by such person. The
person to whom the Option is granted may, by delivering written notice to the
Company, in a form satisfactory to the Company, designate a third party who, in
the event of the death of the Optionee, shall thereafter be entitled to exercise
the Option.

         (e) Vesting. The total number of shares of stock subject to an Option
may, but need not, be allotted in periodic installments (which may, but need
not, be equal). The Option Agreement may provide that from time to time during
each of such installment periods, the Option may become exercisable ("vest")
with respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or any prior period as to which the Option became vested but was not fully
exercised. The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The vesting provisions of
individual Options may vary but in each case will provide for vesting of at
least twenty percent (20%) per year of the total number of shares subject to the
Option. The provisions of this subsection 6(e) are subject to any Option
provisions governing the minimum number of shares as to which an Option may be
exercised.

         (f) Securities Law Compliance. The Company may require any Optionee, or
any person to whom an Option is transferred under subsection 6(d), as a
condition of exercising any such Option, (1) to give written assurances
satisfactory to the Company as to the Optionee's knowledge and experience in
financial and business matters and/or to employ a purchaser representative
reasonably satisfactory to the Company who is knowledgeable and experienced in
financial and business matters, and that he or she is capable of evaluating,
alone or together with the purchaser representative, the merits and risks of
exercising the Option; and (2) to give written assurances satisfactory to the
Company stating that such person is acquiring the stock subject to the Option
for such person's own account and not with any present intention of selling or
otherwise distributing the stock. The foregoing requirements, and any assurances
given pursuant to such requirements, shall be inoperative if (i) the issuance of
the shares upon the exercise of the Option has been registered under a then
currently effective registration statement under the Securities Act, or (ii) as
to any particular requirement, a determination is made by counsel for the
Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The

                                       10
<PAGE>   5

Company may require the Optionee to provide such other representations, written
assurances or information which the Company shall determine is necessary,
desirable or appropriate to comply with applicable securities and other laws as
a condition of granting an Option to such Optionee or permitting the Optionee to
exercise such Option. The Company may, upon advice of counsel to the Company,
place legends on stock certificates issued under the Plan as such counsel deems
necessary or appropriate in order to comply with applicable securities laws,
including, but not limited to, legends restricting the transfer of the stock.

         (g) Termination of Employment or Relationship as a Director or
Consultant. In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability), the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it as of the date of termination) but only
within such period of time ending on the earlier of (i) the date three (3)
months following the termination of the Optionee's Continuous Status as an
Employee, Director or Consultant, or such longer or shorter period, (which shall
not be less than thirty (30) days, specified in the Option Agreement, or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, after termination, the Optionee does not exercise his or her Option within
the time specified in the Option Agreement, the Option shall terminate, and the
shares covered by such Option shall revert to and again become available for
issuance under the Plan.

         (h) Disability of Optionee. In the event an Optionee's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Optionee's disability, the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it as of the date of
termination), but only within such period of time ending on the earlier of (i)
the date twelve (12) months following such termination (or such longer or
shorter period, which in no event shall be less than six (6) months, specified
in the Option Agreement), or (ii) the expiration of the term of the Option as
set forth in the Option Agreement. If, at the date of termination, the Optionee
is not entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.

         (i) Death of Optionee. In the event of the death of an Optionee during,
or within a period specified in the Option Agreement after the termination of,
the Optionee's Continuous Status as an Employee, Director or Consultant, the
Option may be exercised (to the extent the Optionee was entitled to exercise the
Option as of the date of death) by the Optionee's estate, by a person who
acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the Option upon the Optionee's death pursuant to
subsection 6(d), but only within the period ending on the earlier of (i) the
date eighteen (18) months following the date of death (or such longer or shorter
period, which in no event shall be less than six (6) months, specified in the
Option Agreement), or (ii) the expiration of the term of such Option as set
forth in the Option Agreement. If, at the time of death, the Optionee was not
entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan. If, after death, the Option is not exercised within
the time specified herein, the Option shall terminate, and the shares covered by
such Option shall revert to and again become available for issuance under the
Plan.

         (j) Early Exercise. The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option. Any unvested shares so
purchased shall be subject to a repurchase right in favor of the Company, with
the repurchase price to be equal to the original purchase price of the stock, or
to any other restriction the Board determines to be appropriate; provided,
however, that (i) the right to repurchase at the original purchase price shall
lapse at a minimum rate of twenty percent (20%) per year over five (5) years
from the date the Option was granted, and (ii) such right shall be exercisable
only within (A) the ninety (90) day period following the termination of
employment or the relationship as a Director or Consultant, or (B) such longer
period as may be agreed to by the Company and the Optionee (for example, for
purposes of satisfying the requirements of Section 1202(c)(3) of the Code
(regarding "qualified small business stock")), and (iii) such right shall be
exercisable only for cash or cancellation of purchase money indebtedness for the
shares. Notwithstanding the foregoing, shares received upon exercise of an
Option by an officer, director or consultant (within the meaning of Section
260.140.41 of Title 10 of the California Code of Regulations) may be subject to
additional or greater restrictions).

                                       11
<PAGE>   6

         (k) Right of Repurchase. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to
repurchase all or any part of the vested shares exercised pursuant to the
Option; provided, however, that (i) such repurchase right shall be exercisable
only within (A) the ninety (90) day period following the termination of
employment or the relationship as a Director or Consultant, or (B) such longer
period as may be agreed to by the Company and the Optionee (for example, for
purposes of satisfying the requirements of Section 1202(c)(3) of the Code
(regarding "qualified small business stock")), (ii) such repurchase right shall
be exercisable for less than all of the vested shares only with the Optionee's
consent, and (iii) such right shall be exercisable only for cash or cancellation
of purchase money indebtedness for the shares at a repurchase price equal to the
greater of (A) the stock's Fair Market Value at the time of such termination, or
(B) the original purchase price paid for such shares by the Optionee.
Notwithstanding the foregoing, shares received upon exercise of an Option by an
officer, director, or consultant (within the meaning of Section 260.140.41 of
Title 10 of the California Code of Regulations) may be subject to additional or
greater restrictions specified in the Option Agreement.

         (l) Right of First Refusal. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to exercise
a right of first refusal following receipt of notice from the Optionee of the
intent to transfer all or any part of the shares exercised pursuant to the
Option. Such right of first refusal shall be exercised by the Company no more
than thirty (30) days following receipt of notice of the Optionee's intent to
transfer shares and must be exercised as to all the shares the Optionee intends
to transfer unless the Optionee consents to exercise for less than all the
shares offered. The purchase of the shares following exercise shall be completed
within thirty (30) days of the Company's receipt of notice of the Optionee's
intent to transfer shares, or such longer period of time as has been offered by
the person to whom the Optionee intends to transfer the shares, or as may be
agreed to by the Company and the Optionee (for example, for purposes of
satisfying the requirements of Section 1202(c)(3) of the Code (regarding
"qualified small business stock"). Except as expressly provided in this
Subsection (1), such right of first refusal shall otherwise comply with the
provisions of the Bylaws of the Company.

         (m) Withholding. To the extent provided by the terms of an Option
Agreement, the Optionee may satisfy any federal, state or local tax withholding
obligation relating to the exercise of such Option by any of the following means
or by a combination of such means: (1) tendering a cash payment; (2) authorizing
the Company to withhold shares from the shares of the common stock otherwise
issuable to the Optionee as a result of the exercise of the Option; or (3)
delivering to the Company owned and unencumbered shares of the common stock of
the Company.

     7. COVENANTS OF THE COMPANY.

         (a) During the terms of the Options, the Company shall keep available
at all times the number of shares of stock required to satisfy such Options.

         (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the Options; provided, however,
that this undertaking shall not require the Company to register under the
Securities Act either the Plan, any Option or any stock issued or issuable
pursuant to any such Option. If, after reasonable efforts, the Company is unable
to obtain from any such regulatory commission or agency the authority which
counsel for the Company deems necessary for the lawful issuance and sale of
stock under the Plan, the Company shall be relieved from any liability for
failure to issue and sell stock upon exercise of such Options unless and until
such authority is obtained.

     8. USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to Options shall constitute
general funds of the Company.

                                       12

     9. MISCELLANEOUS.

         (a) Subject to any applicable provisions of the California Corporate
Securities Law of 1968 and related regulations relied upon as a condition of
issuing securities pursuant to the Plan, the Board shall have the power to
accelerate the time at which an Option may first be exercised or the time during
which an Option or any part thereof will vest pursuant to subsection 6(e),
notwithstanding the provisions in the Option stating that the time at which it
may first be exercised or the time during which it will vest.

         (b) Neither an Optionee nor any person to whom an Option is transferred
under subsection 6(d) shall be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares subject to such Option unless and
until such person has satisfied all requirements for exercise of the Option
pursuant to its terms.

         (c) Throughout the term of any Option, the Company shall deliver to the
holder of such Option, not later than one hundred twenty (120) days after the
close of each of the Company's fiscal years during the Option term, a balance
sheet and an income statement. This section shall not apply (i) after the
Listing Date, or (ii) when issuance is limited to key employees whose duties in
connection with the Company assure them access to equivalent information.

         (d) Nothing in the Plan or any instrument executed or Option granted
pursuant thereto shall confer upon any Employee, Director, Consultant or
Optionee any right to continue in the employ of the Company or any Affiliate (or
to continue acting as a Director or Consultant or shall affect the right of the
Company or any Affiliate to terminate the employment of any Employee, with or
without cause, to remove any Director as provided in the Company's By-Laws and
the provisions of the General Corporation Law of the State of Delaware, or to
terminate the relationship of any Consultant subject to the terms of that
Consultant's agreement with the Company or Affiliate to which such Consultant is
providing services.

         (e) To the extent that the aggregate Fair Market Value (determined at
the time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

               (1) The Board or the Committee shall have the authority to
effect, at any time and from time to time (i) the repricing of any outstanding
Options under the Plan and/or (ii) with the consent of the affected holders of
Options, the cancellation of any outstanding Options and the grant in
substitution therefor of new Options under the Plan covering the same or
different numbers of shares of common stock, but having an exercise price per
share not less than eighty-five percent (85%) of the Fair Market Value (one
hundred percent (100%) of the Fair Market Value in the case of an Incentive
Stock Option or, in the case of a ten percent (10%) shareholder (as defined in
subsection 5(b)), not less than one hundred and ten percent (110%) of the Fair
Market Value) per share of common stock on the new grant date.

               (2) Shares subject to an Option canceled under this subsection 9
shall continue to be counted, for the applicable period in which it was granted,
against the maximum award of Options permitted to be granted pursuant to
subsection 5(c) of the Plan. The repricing of an Option under this subsection 9
resulting in a reduction of the exercise price, shall be deemed to be a
cancellation of the original Option and the grant of a substitute Option; in the
event of such repricing, both the original and the substituted Options shall be
counted for the applicable period against the maximum awards of Options
permitted to be granted pursuant to subsection 5(c) of the Plan. The provisions
of this subsection 9 (e)(2) shall be applicable only to the extent required by
Section 162(m) of the Code.

     10. ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the stock subject to the Plan, or subject
to any Option (through merger, consolidation, reorganization, recapitalization,
stock dividend, dividend in property other than cash, stock

                                       13
<PAGE>   8

split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan will be appropriately adjusted in the
type(s) and maximum number of securities subject to the Plan pursuant to
subsection 4(a) and the maximum number of securities subject to award, to any
person during any twelve (12) month period pursuant to subsection 5(c), and the
outstanding Options will be appropriately adjusted in the type(s) and number of
securities and price per share of stock subject to such outstanding Options.
Such adjustments shall be made by the Board or Committee, the determination of
which shall be final, binding and conclusive. (The conversion of any convertible
securities of the Company shall not be treated as a "transaction not involving
the receipt of consideration by the Company.")

         (b) In the event of. (1) a dissolution, liquidation or sale of all or
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving corporation; or (3) a reverse merger in
which the Company is the surviving corporation but the shares of the Company's
common stock outstanding immediately preceding the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash or otherwise, then (i) any surviving or acquiring corporation shall assume
any Options outstanding under the Plan or shall substitute similar Options
(including an option to acquire the same consideration paid to the shareholders
in the transaction described in this subsection 10(b)) for those outstanding
under the Plan, or (ii) in the event any surviving or acquiring corporation
refuses to assume such Options, or to substitute similar options for those
outstanding under the Plan, then (A) with respect to Options held by persons
then performing services as Employees, Directors or Consultants and subject to
any applicable provisions of the California Corporate Securities Law of 1968 and
related regulations relied upon as a condition of issuing securities pursuant to
the Plan, the vesting of such Options and the time during which such Options may
be exercised shall be accelerated prior to such event and the Options terminated
if not exercised after such acceleration and at or prior to such event-, and (B)
with respect to any other Options outstanding under the Plan, such Options shall
be terminated if not exercised prior to such event.

     11. AMENDMENT OF THE PLAN AND OPTIONS.

         (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 10 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the shareholders of
the Company within twelve (12) months before or after the adoption of the
amendment, where the amendment will:

               (1) Increase the number of shares reserved for Options under the
Plan;

               (2) Modify the requirements as to eligibility for participation
in the Plan (to the extent such modification requires shareholder approval in
order for the Plan to satisfy the requirements of Section 422 of the Code); or

               (3) Modify the Plan in any other way if such modification
requires shareholder approval in order for the Plan to satisfy the requirements
of Section 422 of the Code or to comply with the requirements of Rule 16b-3.

         (b) The Board may in its sole discretion submit any other amendment to
the Plan for shareholder approval, including, but not limited to, amendments to
the Plan intended to satisfy the requirements of Section 162(m) of the Code and
the regulations promulgated thereunder regarding the exclusion of
performance-based compensation from the limit on corporate deductibility of
compensation paid to certain executive officers.

         (c) It is expressly contemplated that the Board may amend the Plan in
any respect the Board deems necessary or advisable to provide Optionees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to Incentive Stock Options
and/or to bring the Plan and/or Incentive Stock Options granted under it into
compliance therewith.

         (d) Rights and obligations under any Option granted before amendment of
the Plan shall not be impaired by any amendment of the Plan unless (i) the
Company requests the consent of the person to whom the Option was granted and
(ii) such person consents in writing.

         (e) The Board at any time, and from time to time, may amend the terms
of any one or more Options; provided, however, that the rights and obligations
under any Option shall not be impaired by any such amendment unless (i) the
Company requests the consent of the person W whom the Option was granted and
(ii) such person consents in writing.

     12. TERMINATION OR SUSPENSION OF THE PLAN.

         (a) The Board may suspend or terminate the Plan at any time. Unless
sooner terminated, the Plan shall terminate on December 1, 2007, which shall be
within ten (10) years from the date the Plan is adopted by the Board or approved
by the shareholders of the Company, whichever is earlier. No Options may be
granted under the Plan while the Plan is suspended or after it is terminated.

         (b) Rights and obligations under any Option granted while the Plan is
in effect shall not be impaired by suspension or termination of the Plan, except
with the written consent of the person to whom the Option was granted.

     13. EFFECTIVE DATE OF PLAN.

         The Plan shall become effective as determined by the Board, but no
Options granted under the Plan shall be exercised unless and until the Plan has
been approved by the shareholders of the Company, which approval shall be within
twelve (12) months before or after the date the Plan is adopted by the Board

                             INCENTIVE STOCK OPTION

__________, Optionee:

     GigaPixel Corporation (the "Company"), pursuant to its 1997 Employee
Incentive Plan (the "Plan"), has granted to you, the optionee named above, an
option to purchase shares of the common stock of the Company ("Common Stock").
This option is intended to qualify as an "incentive stock option" within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code").

     The grant hereunder is in connection with and in furtherance of the
Company's compensatory benefit plan for participation of the Company's employees
(including officers) and is intended to comply with the provisions of Rule 701
promulgated by the Securities and Exchange Commission under the Securities Act
of 1933, as amended (the "Act"). The grant of this option and the issuance of
shares upon the exercise of this option are also intended to be exempt from the
securities qualification requirements of the California Corporations Code
pursuant to Section 25102(o) of that code. Defined terms not explicitly defined
in this agreement but defined in the Plan shall have the same definitions as in
the Plan.

     The details of your option are as follows:

     1. TOTAL NUMBER OF SHARES SUBJECT TO THIS OPTION. The total number of
shares of Common Stock subject to this option is __________________ (____).

     2. VESTING. Subject to the limitations contained herein, 25% of the shares
will vest (become exercisable) on the first anniversary of the grant date, 25%
will vest on the second anniversary of the grant date and quarterly for two
years thereafter until either (i) you cease to provide services to the Company
for any reason, or (ii) this option becomes fully vested.

     3. EXERCISE PRICE AND METHOD OF PAYMENT.

         (a) EXERCISE PRICE. The exercise price of this option is twelve cents
($0.12) per share, being not less than the fair market value of the Common Stock
on the date of grant of this option.

         (b) METHOD OF PAYMENT. Payment of the exercise price per share is due
in full upon exercise of all or any part of each installment which has accrued
to you. You may elect, to the extent permitted by applicable statutes and
regulations, to make payment of the exercise price under one of the following
alternatives:

               (i) Payment of the exercise price per share in cash (including
check) at the time of exercise;

               (ii) Payment pursuant to a program developed under Regulation T
as promulgated by the Federal Reserve Board which, prior to the issuance of
Common Stock, results in either the receipt of cash (or check) by the Company or
the receipt of irrevocable instructions to pay the aggregate exercise price to
the Company from the sales proceeds;

               (iii) Provided that at the time of exercise the Company's Common
Stock is publicly traded and quoted regularly in the Wall Street Journal,
payment by delivery of already-owned shares of Common Stock, held for the period
required to avoid a charge to the Company's reported earnings, and owned free
and clear of any liens, claims, encumbrances or security interests, which Common
Stock shall be valued at its fair market value on the date of exercise;

               (iv) Payment by a combination of the methods of payment permitted
by subparagraph 3 (b)(i) through 3 (b)(iii) above.

                                       16
<PAGE>   11

     4. EXERCISE PRIOR TO VESTING PERMITTED.

         (a) Conditions of Early Exercise. Subject to the provisions of this
option you may elect at any time during your Continuous Status as an Employee,
Director or Consultant with the Company or an Affiliate of the Company to
exercise the option as to any part or all of the shares subject to this option
at any time during the term hereof, including without limitation, a time prior
to the date of earliest exercise ("vesting") stated in paragraph 2 hereof;
provided, however, that:

               (i) a partial exercise of this option shall be deemed to cover
first vested shares and then the earliest vesting installment of unvested
shares;

               (ii) any shares so purchased from installments which have not
vested as of the date of exercise shall be subject to the purchase option in
favor of the Company as described in the Early Exercise Stock Purchase Agreement
attached hereto;

               (iii) you shall enter into an Early Exercise Stock Purchase
Agreement in the form attached hereto with a vesting schedule that will result
in the same vesting as if no early exercise had occurred; and

               (iv) this option shall not be exercisable under this paragraph 4
to the extent such exercise would cause the aggregate fair market value of any
shares subject to incentive stock options granted you by the Company or any
Affiliate of the Company (valued as of their grant date) which would become
exercisable for the first time during any calendar year to exceed $100,000.

         (b) EXPIRATION OF EARLY EXERCISE ELECTION. The election provided in
this paragraph 4 to purchase shares upon the exercise of this option prior to
the vesting dates shall cease upon termination of your Continuous Status as an
Employee, Director or Consultant with the Company or an Affiliate of the Company
and may not be exercised after the date thereof

     5. WHOLE SHARES. This option may not be exercised for any number of shares
which would require the issuance of anything other than whole shares.

     6. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, this option may not be exercised unless the shares issuable
upon exercise of this option are then registered under the Securities Act of
1933, as amended (the "Act"), or, if such shares are not then so registered, the
Company has determined that such exercise and issuance would be exempt from the
registration requirements of the Act.

     7. TERM. The term of this option commences on ______, the date of grant,
and expires on ____________ (the "Expiration Date," which date shall be no more
than ten (10) years from date this option is granted), unless this option
expires sooner as set forth below or in the Plan. In no event may this option be
exercised on or after the Expiration Date. This option shall terminate prior to
the Expiration Date of its term as follows: thirty (30) days after the
termination of your Continuous Status as an Employee, Director or Consultant
with the Company or an Affiliate of the Company unless one of the following
circumstances exists:

         (a) Your termination of Continuous Status as an Employee, Director or
Consultant is due to your permanent and total disability (within the meaning of
Section 422(c)(6) of the Code). This option will then expire on the earlier of
the Expiration Date set forth above or twelve (12) months following such
termination of Continuous Status as an Employee, Director or Consultant.

         (b) Your termination of Continuous Status as an Employee, Director or
Consultant is due to your death or your death occurs within thirty (30) days
following your termination of Continuous Status as an Employee, Director or
Consultant. This option will then expire on the earlier of the Expiration Date
set forth above or twelve (12) months after your death.

                                       17
<PAGE>   12

         (c) If during any part of such thirty (30) day period you may not
exercise your option solely because of the condition set forth in paragraph 5
above, then your option will not expire until the earlier of the Expiration Date
set forth above or until this option shall have been exercisable for an
aggregate period of thirty (30) days after your termination of Continuous Status
as an Employee, Director or Consultant.

         (d) If your exercise of the option within thirty (30) days after
termination of your Continuous Status as an Employee, Director or Consultant
with the Company or with an Affiliate of the Company would result in liability
under section 16(b) of the Securities Exchange Act of 1934, then your option
will expire on the earlier of (i) the Expiration Date set forth above, (ii) the
tenth (10th) day after the last date upon which exercise would result in such
liability or (iii) six (6) months and ten (10) days after the termination of
your Continuous Status as an Employee, Director or Consultant with the Company
or an Affiliate of the Company.

     However, this option may be exercised following termination of Continuous
Status as an Employee, Director or Consultant only as to that number of shares
as to which it was exercisable on the date of termination of Continuous Status
as an Employee, Director or Consultant under the provisions of paragraph 2 of
this option.

     In order to obtain the federal income tax advantages associated with an
"incentive stock option," the Code requires that at all times beginning on the
date of grant of the option and ending on the day three (3) months before the
date of the option's exercise, you must be an employee of the Company or an
Affiliate of the Company, except in the event of your death or permanent and
total disability. The Company has provided for continued vesting or extended
exercisability of your option under certain circumstances for your benefit but
cannot guarantee that your option will necessarily be treated as an "incentive
stock option" if you provide services to the Company or an Affiliate of the
Company as a consultant or exercise your option more than three (3) months after
the date your employment with the Company and all Affiliates of the Company
terminates.

     8. EXERCISE.

         (a) This option may be exercised, to the extent specified above, by
delivering a notice of exercise (in a form designated by the Company) together
with the exercise price to the Secretary of the Company, or to such other person
as the Company may designate, during regular business hours, together with such
additional documents as the Company may then require pursuant to subsection 6(f)
of the Plan.

         (b) By exercising this option you agree that:

               (i) as a precondition to the completion of any exercise of this
option, the Company may require you to enter an arrangement providing for the
payment by you to the Company of any tax withholding obligation of the Company
arising by reason of (1) the exercise of this option; (2) the lapse of any
substantial risk of forfeiture to which the shares are subject at the time of
exercise; or (3) the disposition of shares acquired upon such exercise;

               (ii) you will notify the Company in writing within fifteen (15)
days after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of this option that occurs within two (2) years after the
date of this option grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of this option; and

     9. TRANSFERABILITY. This option is not transferable, except by will or by
the laws of descent and distribution, and is exercisable during your life only
by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise this
option.

     10. OPTION NOT A SERVICE CONTRACT. This option is not an employment
contract and nothing in this option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue your employment with the Company. In addition,
nothing in this option shall obligate the Company or any Affiliate of the
Company, or their respective stockholders, Board of Directors, officers or
employees to continue any relationship which you might have as a Director or
Consultant for the Company or Affiliate of the Company.

                                       18
<PAGE>   13

     11. NOTICES. Any notices provided for in this option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by the Company to you, five (5) days after deposit in
the United States mail, postage prepaid, addressed to you at the address
specified below or at such other address as you hereafter designate by written
notice to the Company.

     12. GOVERNING PLAN DOCUMENT. This option is subject to all the provisions
of the Plan, a copy of which is attached hereto and its provisions are hereby
made a part of this option, including without limitation the provisions of
Section 6 of the Plan relating to option provisions, and is further subject to
all interpretations, amendments, rules and regulations which may from time to
time be promulgated and adopted pursuant to the Plan. In the event of any
conflict between the provisions of this option and those of the Plan, the
provisions of the Plan shall control.

         Dated the____day of_______________, _____.

                              GIGAPIXEL CORPORATION

                     EARLY EXERCISE STOCK PURCHASE AGREEMENT

     THIS AGREEMENT is made effective as of __________, _____ by and between
GIGAPIXEL CORPORATION., a Delaware corporation (the "Company"), and
______________ ("Purchaser").

WITNESSETH:

     WHEREAS, Purchaser holds an option to purchase shares of Common Stock of
the Company pursuant to the Company's 1997 Stock Option Plan (the "Plan") that
Purchaser desires to exercise; and

     WHEREAS, Purchaser wishes to take advantage of the early exercise provision
of Purchaser's option and therefore to enter into this Agreement;

     NOW, THEREFORE, IT IS AGREED between the parties as follows:

     1. Purchaser hereby agrees to purchase from the Company, and the Company
hereby agrees to sell to Purchaser, an aggregate of ____________ shares of the
Common Stock of the Company (the "Stock"), for an exercise price of
$_____________ per share (total exercise price: ______________ ($________)),
payable as follows:

             Cash at Closing                    $
                                                 -----------------------------
             Value of ______ shares of
             Company Common Stock               $
                                                 -----------------------------
             Total Exercise Price               $
                                                 -----------------------------

     The closing hereunder shall occur at the offices of the Company on the date
of this Agreement or at such other time and place as the parties may mutually
agree upon in writing.

     At the closing, Purchaser shall deliver three (3) stock assignments in the
form of EXHIBIT A, duly endorsed (with date and number of shares left blank),
joint escrow instructions (the "Joint Escrow Instructions") in the form of
EXHIBIT B, duly executed by Purchaser.

     At the closing or as soon thereafter as practicable, the Company shall
deliver to the Escrow Agent (as defined in paragraph 8 below) share certificates
for all of the Stock that is to be subject to the Purchase Option (as defined in
paragraph 2 below), and shall deliver share certificates to Purchaser for all of
the Stock, if any, that is not to be subject to the Purchase Option.

     2. In accordance with the provisions of section 408(b) of the California
General Corporation Law, the Stock to be purchased by Purchaser pursuant to this
Agreement shall be subject to the following option ("Purchase Option"):

         (a) In the event that Purchaser's Continuous Service (as defined in the
Plan) shall cease for any reason (including his death), or no reason, with or
without cause, the Purchase Option may be exercised. The Company shall have the
right at any time within the ninety (90) day period after termination of
Purchaser's Continuous Service or such longer period as may be agreed to by the
Company and Purchaser (for example, for purposes of satisfying the requirements
of Section 1202(c)(3) of the Internal Revenue Code of 1986, as amended) to
purchase from Purchaser or Purchaser's personal representative, as the case may
be, at the price per share paid by Purchaser pursuant to this Agreement ("Option
Price"), up to but not exceeding the number of shares of the Stock set forth on
Schedule I hereto which is incorporated herein by this reference.

                                       21
<PAGE>   16

         (b) In addition, and without limiting the foregoing Purchase Option, if
at any time during the term of the Purchase Option, there occurs an event
described in subsections 10(b) through and including 10(e) of the Plan, then:
(i) the Company shall exercise the Purchase Option to the same extent that
unvested Options would have terminated under the applicable subsection (e.g. the
occurrence of the dissolution or liquidation of the Company would require the
Company to exercise the Purchase Option), or (ii) the Purchase Option shall
lapse to the same extent that unvested Options would have become vested in full
under the applicable subsection (e.g. the occurrence of a merger under
subsection 10(c) in which outstanding options are not assumed or substituted
would result in the lapse of the Purchase Option in its entirety if Purchaser's
Continuous Service had not terminated prior to such merger), or (iii) the
Purchase Option may be assigned to any successor to the Company to the same
extent that Options are assumed or substituted by such successor under the
applicable subsection, and the Purchase Option shall apply if Purchaser's
Continuous Service with such a successor shall cease for any reason on the same
basis as set forth above. In that case, references herein to the "Company" shall
be deemed to refer to such successor.

         (c) The Company shall be entitled to pay for any shares purchased
pursuant to its Purchase Option at the Company's option in cash.

         (d) This Agreement is not an employment contract and nothing in this
Agreement shall be deemed to create in any way whatsoever any obligation on the
part of Purchaser to continue in the employ of the Company, or of the Company to
continue Purchaser in the employ of the Company. As used herein, employment with
the Company shall include employment with an Affiliate (as defined in the Plan).

     3. The Purchase Option may be exercised by giving written notice of
exercise delivered or mailed as provided in paragraph 13. Upon providing of such
notice and payment or tender of the purchase price, the Company shall become the
legal and beneficial owner of the Stock being purchased and all rights and
interests therein or related thereto.

     4. If from time to time during the term of the Purchase Option there is any
stock dividend or liquidating dividend or distribution of cash and/or property,
stock split or other change in the character or amount of any of the outstanding
securities of the Company, then, in such event, any and all new, substituted or
additional securities or other property to which Purchaser is entitled by reason
of his ownership of Stock will be immediately subject to the Purchase Option and
be included in the word "Stock" for all purposes of the Purchase Option with the
same force and effect as the shares of Stock then subject to the Purchase
Option. While the total Option Price shall remain the same after each such
event, the Option Price per share of Stock upon exercise of the Purchase Option
shall be appropriately adjusted.

     5. All certificates representing any shares of Stock subject to the
provisions of this Agreement shall have endorsed thereon legends in
substantially the following form:

         (i) "The shares represented by this certificate are subject to an
option set forth in an agreement between the corporation and the registered
holder, or his predecessor in interest, a copy of which is on file at the
principal office of this corporation. Any transfer or attempted transfer of any
shares subject to such option is void without the prior express written consent
of the issuer of these shares."

         (ii) "These securities have not been registered under the Securities
Act of 1933. They may not be sold, offered for sale, pledged or hypothecated in
the absence of an effective registration statement as to the securities under
said Act or an opinion of counsel satisfactory to the corporation that such
registration is not required."

         (iii) Any legend required to be placed thereon by the California
Commissioner of Corporations.

     6. Purchaser acknowledges that Purchasersis aware that the Stock to be
issued to Purchaser by the Company pursuant to this Agreement has not been
registered under the Securities Act of 1933, as amended (the "Act"), on the
basis that no distribution or public offering of the Stock is to be effected,
and in this connection acknowledges that the Company is relying on the following
representations. In this connection, Purchaser warrants

                                       22
<PAGE>   17

and represents to the Company that Purchaser is acquiring the Stock for
investment and not with a view to or for sale in connection with any
distribution of the Stock or with any present intention of distributing or
selling the Stock, and Purchaser does not presently have reason to anticipate
any change in circumstances or any particular occasion or event which would
cause Purchaser to sell the Stock. Purchaser recognizes that the Stock must be
held indefinitely unless it is subsequently registered under the Act or an
exemption from such registration is available and, further, recognizes that the
Company is under no obligation to register the Stock or to comply with any

                  (k) "Employee" means any person, including officers and
directors, employed by the Company or any Parent or Subsidiary of the Company.

as amended.

                  (m) "Fair Market Value" means, as of any date, the value of

                           (1) If the Common Stock is listed on any established
stock exchange or a national market system, including without limitation the
Nasdaq National Market or The Nasdaq SmallCap Market of The Nasdaq Stock Market,
its Fair Market Value shall be the closing sales price for such stock (or the
closing bid, if no sales were reported) as quoted on such exchange or system for
the last market trading day prior to the time of determination, as reported in
The Wall Street Journal or such other source as the Administrator deems
reliable;

                           (2) If the Common Stock is regularly quoted by a
recognized securities dealer but selling prices are not reported, the Fair
Market Value of a Share of Common Stock shall be the mean between the high bid
and low asked prices for the Common Stock on the last market trading day prior
to the day of determination, as reported in The Wall Street Journal or such
other source as the Administrator deems reliable; or

                           (3) In the absence of an established market for the
Common Stock, the Fair Market Value shall be determined in good faith by the
Administrator.

                  (n) "Incentive Stock Option" means an Option intended to
qualify as an incentive stock option within the meaning of Section 422 of the

         3. Stock Subject to the Plan.

         Subject to the provisions of Section 11 of the Plan, the maximum
         aggregate number of shares which may be optioned and sold under the
         Plan is 8,875,000 shares of Common Stock. The shares may be authorized,
         but unissued, or reacquired Common Stock.

         If an Option expires or becomes unexercisable without having been
         exercised in full, or is surrendered pursuant to an Option repricing or
         Option exchange, the unpurchased Shares which were subject thereto
         shall become available for future grant or sale under the Plan (unless
         the Plan has terminated); provided, however, that Shares that have
         actually been issued under the Plan upon exercise of an Option shall
         not be returned to the Plan

                                      -2-
<PAGE>   3

         and shall not become available for future distribution under the Plan,
         except that if Shares of Restricted Stock are repurchased by the
         Company at their original purchase price, such Shares shall become
         available for future grant under the Plan.

         4. Administration of the Plan.

                  (a) Procedure.

                           (1) Multiple Administrative Bodies. The Plan may be
administered by different Committees with respect to different groups of
Employees and Consultants.

                           (2) Section 162(m). To the extent that the
Administrator determines it to be desirable to qualify Options granted hereunder
as "performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

                           (3) Rule 16b-3. To the extent desirable to qualify
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3.

                           (4) Other Administration. Other than as provided
above, the Plan shall be administered by (A) the Board or (B) a Committee, which
committee shall be constituted to satisfy Applicable Laws.

                  (b) Powers of the Administrator.

                  Subject to the provisions of the Plan and in the case of a
                  Committee, the specific duties delegated by the Board to such
                  Committee, the Administrator shall have the authority, in its
                  discretion:

                           (1) to determine the Fair Market Value;

                           (2) to select the Employees and Consultants to whom
Options may be granted hereunder;

                           (3) to determine the number of shares of Common Stock
to be covered by each Option granted hereunder;

                           (4) to approve forms of agreement for use under the
Plan;

                           (5) to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any Option granted hereunder. Such
terms and conditions include, but are not limited to, the exercise price, the
time or times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option of the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                           (6) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was
granted;

                           (7) to institute an Option repricing or Option
exchange program;

                           (8) to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;

                           (9) to prescribe, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of qualifying for preferred tax treatment
under foreign tax laws;

                                      -3-
<PAGE>   4

                           (10) to modify or amend each Option (subject to
Section 15(c) of the Plan), including the discretionary authority to extend the
post-termination exercisability period of Options longer than is otherwise
provided for in the Plan;

                           (11) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market Value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined. All elections by an Optionee to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable;

                           (12) to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option previously
granted by the Administrator; or

                           (13) to make all other determinations deemed
necessary or advisable for administering the Plan.

                  (c) Effect of Administrator's Decision. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.

         5. Eligibility.

                  (a) Nonstatutory Stock Options may be granted to Employees and
Consultants. Incentive Stock Options may be granted only to Employees. An
Employee or Consultant who has been granted an Option may, if he or she is
otherwise eligible, be granted an additional Option or Options.

                  (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.

                  (c) For purposes of Section 5(b), Incentive Stock Options
shall be taken into account in the order in which they were granted, and the
Fair Market Value of the Shares shall be determined as of the time the Option
with respect to such Shares is granted.

                  (d) The Plan shall not confer upon any Optionee any right with
respect to continuation of the Optionee's employment or consulting relationship
with the Company, nor shall it interfere in any way with his right or the
Company's right to terminate the Optionee's employment or consulting
relationship at any time, with or without cause.

         6. Term of Plan.

         The Plan shall become effective upon the earlier to occur of its
         adoption by the Board of Directors or its approval by the shareholders
         of the Company as described in Section 18 of the Plan. It shall
         continue in effect for a term of ten (10) years unless sooner
         terminated under Section 14 of the Plan.

         7. Term of Option.

         The term of each Option shall be the term stated in the Option
         Agreement; provided, however, that in the case of an Incentive Stock
         Option, the term shall be no more than ten (10) years from the date of
         grant thereof or such shorter term as may be provided in the Option
         Agreement. However, in the case of an Option granted to an Optionee
         who, at the time the Option is granted, owns stock representing more
         than ten percent (10%) of the

                                      -4-
<PAGE>   5

         voting power of all classes of stock of the Company or any Parent or
         Subsidiary, the term of the Option shall be five (5) years from the
         date of grant thereof or such shorter term as may be provided in the
         Option Agreement.

         8. Option Exercise Price and Consideration.

                  (a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Board, but shall be subject to the following:

                           (1) In the case of an Incentive Stock Option

                                    (1) granted to an Employee who, at the time
of the grant of such Incentive Stock Option, owns stock representing more than
ten percent (10%) of the voting power of all classes of stock of the Company or
any Parent or Subsidiary, the per Share exercise price shall be no less than
110% of the Fair Market Value per Share on the date of grant.

                                    (2) granted to any other Employee, the per
Share exercise price shall be no less than 100% of the Fair Market Value per
Share on the date of grant.

                           (2) In the case of a Nonstatutory Stock Option, the
per Share exercise price shall be determined by the Administrator. In the case
of a Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                           (3) Notwithstanding the foregoing, Options may be
granted with a per Share exercise price of less than 100% of the Fair Market
Value per Share on the date of grant pursuant to a merger or other corporate
transaction.

                  (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (i) cash, (ii)
check, (iii) other Shares which (x) in the case of Shares acquired upon exercise
of an Option either have been owned by the Optionee for more than six months on
the date of surrender or were not acquired, directly or indirectly, from the
Company, and (y) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised, (iv) authorization from the Company to retain from the total number
of Shares as to which the Option is exercised that number of Shares having a
Fair Market Value on the date of exercise equal to the exercise price for the
total number of Shares as to which the Option is exercised, (v) delivery of a
properly executed exercise notice together with irrevocable instructions to a
broker to promptly deliver to the Company the amount of sale or loan proceeds
required to pay the exercise price, (vi) any combination of the foregoing
methods of payment, (viii) or such other consideration and method of payment
for the issuance of Shares to the extent permitted under Applicable Laws.

         9. Exercise of Option.

                  (a) Procedure for Exercise: Rights as a Shareholder. Any
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, including performance criteria
with respect to the Company and/or the Optionee, and as shall be permissible
under the terms of the Plan.

                  An Option may not be exercised for a fraction of a Share.

                  An Option shall be deemed to be exercised when written notice
                  of such exercise has been given to the Company in accordance
                  with the terms of the Option by the person entitled to
                  exercise the Option and full payment for the Shares with
                  respect to which the Option is exercised has been received by
                  the Company. Full payment may, as authorized by the Board,
                  consist of any consideration and method of payment allowable
                  under Section 8(b) of the Plan. Until the issuance (as
                  evidenced by the appropriate entry on the books of the Company
                  or of a duly authorized transfer agent of the Company) of the
                  stock certificate evidencing such Shares, no right to vote or
                  receive dividends or any other rights as a shareholder shall
                  exist with respect to the Optioned Stock, notwithstanding the
                  exercise of the Option.

                                      -5-
<PAGE>   6

                  The Company shall issue (or cause to be issued) such stock
                  certificate promptly upon exercise of the Option. No
                  adjustment will be made for a dividend or other right for
                  which the record date is prior to the date the stock
                  certificate is issued, except as provided in Section 11 of the
                  Plan.

                  Exercise of an Option in any manner shall result in a decrease
                  in the number of Shares which thereafter may be available,
                  both for purposes of the Plan and for sale under the Option,
                  by the number of Shares as to which the Option is exercised.

                  (b) Termination of Employment. In the event of termination of
an Optionee's consulting relationship or Continuous Status as an Employee with
the Company (but not upon a change of status from an Employee to Consultant or
Consultant to Employee), such Optionee may, but only within the period stated in
the Option Agreement (which, in the case of an Incentive Stock Option, shall be
no more than ninety (90) days after the date of such termination and, in the
case of any Option, shall be no later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise the Option to the
extent that Optionee was entitled to exercise it at the date of such
termination. To the extent that Optionee was not entitled to exercise the Option
at the date of such termination, or if Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate.

                  (c) Disability of Optionee. Notwithstanding the provisions of
Section 9(b) above, in the event of termination of an Optionee's Consulting
relationship or Continuous Status as an Employee as a result of his or her total
and permanent disability (as defined in Section 22(e)(3) of the Code), Optionee
may, but only within twelve (12) months from the date of such termination (but
in no event later than the expiration date of the term of such Option as set
forth in the Option Agreement), exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination. To the extent that
Optionee is not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate.

                  (d) Death of Optionee. In the event of the death of an
Optionee, the Option may be exercised, at any time within twelve (12) months
following the date of death (but in no event later than the expiration date of
the term of such Option as set forth in the Option Agreement), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent the Optionee is entitled to exercise the
Option on the date of death. To the extent that Optionee is not entitled to
exercise the Option on the date of death, or if the Option is not exercised to
the extent so exercisable within the time specified herein, the Option shall
terminate.

         10. Non-Transferability of Options.

         Unless determined otherwise by the Administrator, an Option may not be
         sold, pledged, assigned, hypothecated, transferred, or disposed of in
         any manner other than by will or by the laws of descent or distribution
         and may be exercised, during the lifetime of the Optionee, only by the
         Optionee. If the Administrator makes an Option transferable, such
         Option shall contain such additional terms and conditions as the
         Administrator deems appropriate.

         11. Adjustments Upon Changes in Capitalization or Merge.

                  (a) Changes in Capitalization. Subject to any required action
by the shareholders of the Company, the number of shares of Common Stock covered
by each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into

                                      -6-
<PAGE>   7

shares of stock of any class, shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares of Common Stock
subject to an Option.

                  (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

                  (c) Merger or Asset Sale. In the event of a merger of the
Company with or into another corporation, or the sale of substantially all of
the assets of the Company, each outstanding Option shall be assumed or an
equivalent option or right substituted by the successor corporation or a Parent
or Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option, the Optionee shall
fully vest in and have the right to exercise the Option as to all of the
Optioned Stock, including Shares as to which it would not otherwise be vested or
exercisable. If an Option becomes fully vested and exercisable in lieu of
assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option shall be fully vested and exercisable for a period of fifteen (15) days
from the date of such notice, and the Option shall terminate upon the expiration
of such period. For the purposes of this paragraph, the Option shall be
considered assumed if, following the merger or sale of assets, the option or
right confers the right to purchase or receive, for each Share of Optioned Stock
subject to the Option immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received in
the merger or sale of assets by holders of Common Stock for each Share held on
the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided, however, that if such consideration received
in the merger or sale of assets is not solely common stock of the successor
corporation or its Parent, the Administrator may, with the consent of the
successor corporation, provide for the consideration to be received upon the
exercise of the Option, for each Share of Optioned Stock subject to the Option,
to be solely common stock of the successor corporation or its Parent equal in
fair market value to the per share consideration received by holders of Common
Stock in the merger or sale of assets.

         12. Time of Granting Options.

         The date of grant of an Option shall, for all purposes, be the date on
         which the Administrator makes the determination granting such Option,
         or such other date as is determined by the Board. Notice of the
         determination shall be given to each Employee or Consultant to whom an
         Option is so granted within a reasonable time after the date of such
         grant.

         13. Limitations.

                  (a) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or as a Nonstatutory Stock Option.
However, notwithstanding such designation, to the extent that the aggregate Fair
Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

                  (b) Neither the Plan nor any Option shall confer upon an
Optionee any right with respect to continuing the Optionee's employment or
consulting relationship with the Company, nor shall they interfere in any way
with the Optionee's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

                                      -7-
<PAGE>   8

                  (c) The following limitations shall apply to grants of Options
to Employees:

                           (1) No Employee shall be granted, in any fiscal year
of the Company, Options to purchase more than 150,000 (post-split) Shares.

                           (2) In connection with his or her initial employment,
an Employee may be granted Options to purchase up to an additional 250,000
(post-split) Shares which shall not count against the limit set forth in
subsection (i) above.

                           (3) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11.

                           (4) If an Option is cancelled in the same fiscal year
of the Company in which it was granted (other than in connection with a
transaction described in Section 11), the cancelled Option will be counted
against the limits set forth in subsections (i) and (ii) above. For this
purpose, if the exercise price of an Option is reduced, the transaction will be
treated as a cancellation of the Option and the grant of a new Option.

         14. Amendment and Termination of the Plan.

                  (a) Amendment and Termination. The Board may at any time
amend, alter, suspend or terminate the Plan.

                  (b) Shareholder Approval. The Company shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

                  (c) Effect of Amendment or Termination. No amendment,
alteration, suspension or termination of the Plan shall impair the rights of any
Optionee, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee and
the Company. Termination of the Plan shall not affect the Administrator's
ability to exercise the powers granted to it hereunder with respect to Options
granted under the Plan prior to the date of such termination.

         15. Conditions Upon Issuance of Shares.

         Shares shall not be issued pursuant to the exercise of an Option unless
         the exercise of such Option and the issuance and delivery of such
         Shares pursuant thereto shall comply with all Applicable Laws, and
         shall be further subject to the approval of counsel for the Company
         with respect to such compliance. As a condition to the exercise of an
         Option, the Company may require the person exercising such Option to
         represent and warrant at the time of any such exercise that the Shares
         are being purchased only for investment and without any present
         intention to sell or distribute such Shares if, in the opinion of
         counsel for the Company, such a representation is required.

         16. Reservation of Shares.

         The Company, during the term of this Plan, will at all time's reserve
         and keep available such number of Shares as shall be sufficient to
         satisfy the requirements of the Plan.

         17.

         The inability of the Company to obtain authority from any regulatory
         body having jurisdiction, which authority is deemed by the Company's
         counsel to be necessary to the lawful issuance and sale of any Shares
         hereunder, shall relieve the Company of any liability in respect of the
         failure to issue or sell such Shares as to which such requisite
         authority shall not have been obtained.

         18. Shareholder Approval.

         Continuance of the Plan shall be subject to approval by the
         shareholders of the Company within twelve (12) months before or after
         the date the Plan is adopted. Such shareholder approval shall be
         obtained in the degree and manner required under applicable state and
         federal law.
