                          CHANGE OF CONTROL AGREEMENT

     This Change of Control Agreement (the "Agreement") is made and entered into
effective as of August 30, 2000, by and between DAVID COOPER (the "Employee")
and AvantGo, Inc., a Delaware corporation (the "Company").

                                    RECITALS

     A.  The Board of Directors of the Company (the "Board") believes that it is
in the best interests of the Company and its stockholders to provide the
Employee with an incentive to continue his or her employment with the Company.

     B.  The Board believes that it is imperative to provide the Employee with
certain benefits upon termination of the Employee's employment (i) in connection
with a Change of Control (defined below); and (ii) within one year of Employee's
commencement of employment with the Company.

     In consideration of the mutual covenants herein contained, and in
consideration of the continuing employment of Employee by the Company, the
parties agree as follows:

          1.  At-Will Employment.  The Company and the Employee acknowledge that
              ------------------
the Employee's employment is and shall continue to be at-will, as defined under
applicable law. If the Employee's employment terminates for any reason,
including (without limitation) any termination prior to a Change of Control, the
Employee shall not be entitled to any compensation, other than (i) as set forth
in Section 2(b), if applicable; and (ii) as may be available in accordance with
the Company's established employee plans and written policies at the time of
termination. The terms of this Agreement shall terminate upon the earliest of
(a) the date on which Employee ceases to be employed as an employee of the
Company, (b) the date that all obligations of the parties hereunder have been
satisfied, or (c) one (1) year after a Change of Control.

          2.  Change of Control.
              -----------------

              (a) Termination Following A Change of Control.  If the Employee's
                  -----------------------------------------
employment with the Company is terminated at any time within one (1) year after
a Change of Control, then the Employee shall be entitled to receive severance
benefits as follows:

                  (i)   Voluntary Resignation or Termination for Cause.  If (A)
                        ----------------------------------------------
the Employee voluntarily resigns from the Company (other than as an Involuntary
Termination (as defined below)) or (B) the Company terminates the Employee's
employment for Cause (as defined below), then the Employee shall not be entitled
to receive any additional compensation.  The Employee's benefits will be
terminated under the Company's then existing benefit plans and policies in
accordance with such plans and policies in effect on the date of termination or
as otherwise determined by the Board of Directors of the Company.

                  (ii)  Involuntary Termination.  If the Employee's employment
                        -----------------------
is terminated as a result of an Involuntary Termination other than for Cause,
the Employee shall be entitled to receive immediate vesting of a portion of each
unvested stock option and restricted stock grant for the Company's securities
held by the Employee on the date of termination such that (a)

<PAGE>

each such option shall be vested with respect to an additional 50% of the
shares thereunder (but not to exceed 100% of the shares thereunder) on the
termination date in accordance with the provisions of the Option Agreement and
Plan pursuant to which such option was granted and (b) the Company's repurchase
rights with respect to each such restricted stock grant shall lapse with respect
to an additional 50% of the shares thereunder (but not to exceed 100% of the
shares thereunder) on the termination date in accordance with the provisions of
the Restricted Stock Purchase Agreement pursuant to which such restricted stock
was sold.

               (b) Termination Apart from a Change of Control.  If the
                   ------------------------------------------
Employee's employment with the Company is terminated at any time, then the
Employee shall be entitled to receive severance benefits as follows:

                   (i)  Voluntary Resignation or Termination for Cause.  If (A)
                        ----------------------------------------------
the Employee voluntarily resigns from the Company (other than as an Involuntary
Termination (as defined below)) or (B) the Company terminates the Employee's
employment for Cause (as defined below), then the Employee shall not be entitled
to receive any additional compensation. The Employee's benefits will be
terminated under the Company's then existing benefit plans and policies in
accordance with such plans and policies in effect on the date of termination or
as otherwise determined by the Board of Directors of the Company.

                   (ii) Involuntary Termination.  If the Employee's employment
                        -----------------------
is terminated as a result of an Involuntary Termination other than for Cause,
the Employee shall be entitled to receive immediate vesting of a portion of each
unvested stock option and restricted stock grant for the Company's securities
held by the Employee on the date of termination such that (a) each such option
shall be vested with respect to an additional 25% of the shares thereunder (but
not to exceed 100% of the shares thereunder) on the termination date in
accordance with the provisions of the Option Agreement and Plan pursuant to
which such option was granted and (b) the Company's repurchase rights with
respect to each such restricted stock grant shall lapse with respect to an
additional 25% of the shares thereunder (but not to exceed 100% of the shares
thereunder) on the termination date in accordance with the provisions of the
Restricted Stock Purchase Agreement pursuant to which such restricted stock was
sold.

                  ------------
the application thereof to any circumstance shall, in any jurisdiction and to
any extent, be invalid or unenforceable, such term or provision shall be
ineffective as to such jurisdiction to the extent of such invalidity or
unenforceability without invalidating or rendering unenforceable the remaining
terms and provisions of this Agreement or the application of such terms and
provisions to circumstances other than those as to which it is held invalid or
unenforceable, and a suitable and equitable term or provision shall be

intent and purpose of the invalid or unenforceable term or provision.

                  ----------------
Agreement will be subject to withholding of applicable income and employment
taxes.

              (j) Assignment by Company.  The Company may assign its rights
                  ---------------------
under this Agreement to an affiliate, and an affiliate may assign its rights
under this Agreement to another affiliate of the Company or to the Company;
provided, however, that no assignment shall be made if the net worth of the
assignee is less than the net worth of the Company at the time of assignment. In
the case of any such assignment, the term "Company" when used in a section of
this Agreement shall mean the corporation that actually employs the Employee.

each of which shall be deemed an original, but all of which together will
constitute one and the same instrument.

within the limitations of, the express provisions of the Plan:

          (i)    To determine from time to time which of the persons eligible
under the Plan shall be granted Stock Awards; when and how each Stock Award
shall be granted; what type or combination of types of Stock Award shall be
granted; the provisions of each Stock Award granted (which need not be
identical), including the time or times when a person shall be permitted to
receive Common Stock pursuant to a Stock Award; and the number of shares of
Common Stock with respect to which a Stock Award shall be granted to each such
person.

          (ii)   To construe and interpret the Plan and Stock Awards 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 Stock Award Agreement,
in a manner and to the extent it shall deem necessary or expedient to make the
Plan fully effective.

          (iii)  To amend the Plan or a Stock Award as provided in Section 12.

          (iv)   Generally, to exercise such powers and to perform such acts as
the Board deems necessary or expedient to promote the best interests of the
Company which are not in conflict with the provisions of the Plan.

  (c)     Delegation to Committee.

          (i)    General. The Board may delegate administration of the Plan to a
Committee or Committees of one (1) or more members of the Board, and the term
"Committee" shall apply to any person or persons to whom such authority has been
delegated. 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, including the power to delegate to a subcommittee any of
the administrative powers the Committee is authorized to exercise (and
references in this Plan to the Board shall thereafter be to the Committee or
subcommittee), 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.

          (ii)   Committee Composition when Common Stock is Publicly Traded. At
such time as the Common Stock is publicly traded, in the discretion of the
Board, a Committee

                                       5
<PAGE>

may consist solely of two or more Outside Directors, in accordance with Section
162(m) of the Code, and/or solely of two or more Non-Employee Directors, in
accordance with Rule 16b-3. Within the scope of such authority, the Board or the
Committee may (1) delegate to a committee of one or more members of the Board
who are not Outside Directors the authority to grant Stock Awards to eligible
persons who are either (a) not then Covered Employees and are not expected to be
Covered Employees at the time of recognition of income resulting from such Stock
Award or (b) not persons with respect to whom the Company wishes to comply with
Section 162(m) of the Code and/or) (2) delegate to a committee of one or more
members of the Board who are not Non-Employee Directors the authority to grant
Stock Awards to eligible persons who are not then subject to Section 16 of the
Exchange Act.

     (d)  Effect of Board's Decision. All determinations, interpretations and
constructions made by the Board in good faith shall not be subject to review by
any person and shall be final, binding and conclusive on all persons.

4.   Shares Subject to the Plan.

     (a)  Share Reserve. Subject to the provisions of Section 11 relating to
adjustments upon changes in Common Stock, the Common Stock that may be issued
pursuant to Stock Awards shall not exceed in the aggregate ten million five
hundred thousand (10,500,000) shares of Common Stock (4.6 million shares
reserved under the 1992 Stock Option Plan plus 4.5 million shares reserved under
the 1997 Stock Option Plan plus 1.4 million share increase).

     (b)  Additional Shares. The aggregate number of shares of Common Stock that
may be issued pursuant to Awards granted under the Plan as specified in
subsection 4(a) shall automatically be increased as follows:

          (i)    For a period of ten (10) years, commencing on June 30, 2000 and
ending on June 30, 2009, the aggregate number of shares of Common Stock
specified in paragraph 4(a) hereof automatically shall be increased each June
(the "Calculation Date") by the greater of (1) five percent (5%) of the Diluted
Shares Outstanding on the Calculation Date, or (2) that number of shares subject
to Awards granted under the Plan during the prior 12-month period.

          (ii)   "Diluted Shares Outstanding" means the number of outstanding
shares of Common Stock on the Calculation Date, plus the number of shares of
Common Stock issuable upon the Calculation Date assuming the conversion of all
outstanding Preferred Stock and convertible notes, plus the additional number of
dilutive Common Stock equivalent shares outstanding as the result of any options
or warrants outstanding during the prior 12-month period, calculated using the
treasury stock method.

          (iii)  The maximum aggregate number of shares of Common Stock that are
available for issuance as Incentive Stock Options under the Plan shall not
exceed twenty three million one hundred thousand (23,100,000) shares of Common
Stock.

     (c)  Reversion of Shares to the Share Reserve. If any Stock Award shall for
any reason expire or otherwise terminate, in whole or in part, without having
been exercised in full,

                                       6
<PAGE>

the shares of Common Stock not acquired under such Stock Award shall revert to
and again become available for issuance under the Plan. If the Company
repurchases any unvested shares of Common Stock issued under a Stock Award, such
repurchased shares of Common Stock shall revert to and again become available
for issuance under the Plan for all Stock Awards other than Incentive Stock
Options.

     (d)  Source of Shares. The shares of Common Stock subject to the Plan may
be unissued shares or reacquired shares, bought on the market or otherwise.

     (e)  Share Reserve Limitation. Prior to the Listing Date and to the extent
then required by Section 260.140.45 of Title 10 of the California Code of
Regulations, the total number of shares of Common Stock issuable upon exercise
of all outstanding Options and the total number of shares of Common Stock
provided for under any stock bonus or similar plan of the Company shall not
exceed the applicable percentage as calculated in accordance with the conditions
and exclusions of Section 260.140.45 of Title 10 of the California Code of
Regulations, based on the shares of Common Stock of the Company that are
outstanding at the time the calculation is made.

5.   Eligibility.

     (a)   Eligibility for Specific Stock Awards. Incentive Stock Options may be
granted only to Employees. Stock Awards other than Incentive Stock Options may
be granted to Employees, Directors and Consultants.

     (b)   Ten Percent Stockholders.

           (i)   A Ten Percent Stockholder shall not be granted an Incentive
Stock Option unless the exercise price of such Option is at least one hundred
ten percent (110%) of the Fair Market Value of the Common Stock at the date of
grant and the Option is not exercisable after the expiration of five (5) years
from the date of grant.

           (ii)  Prior to the Listing Date, a Ten Percent Stockholder shall not
be granted a Nonstatutory Stock Option unless the exercise price of such Option
is at least (i) one hundred ten percent (110%) of the Fair Market Value of the
Common Stock at the date of grant or (ii) such lower percentage of the Fair
Market Value of the Common Stock at the date of grant as is permitted by Section
260.140.41 of Title 10 of the California Code of Regulations at the time of the
grant of the Option.

           (iii) Prior to the Listing Date, a Ten Percent Stockholder shall not
be granted a restricted stock award unless the purchase price of the restricted
stock is at least (i) one hundred percent (100%) of the Fair Market Value of the
Common Stock at the date of grant or (ii) such lower percentage of the Fair
Market Value of the Common Stock at the date of grant as is permitted by Section
260.140.41 of Title 10 of the California Code of Regulations at the time of the
grant of the Option.

                                       7
<PAGE>

     (c)  Section 162(m) Limitation. Subject to the provisions of Section 11
relating to adjustments upon changes in the shares of Common Stock, no Employee
shall be eligible to be granted Options covering more than seven hundred
thousand (700,000) shares of Common Stock during any calendar year. This
subsection 5(c) shall not apply prior to the Listing Date and, following the
Listing Date, this subsection 5(c) shall not apply until (i) the earliest of:
(1) the first material modification of the Plan (including any increase in the
number of shares of Common Stock reserved for issuance under the Plan in
accordance with Section 4); (2) the issuance of all of the shares of Common
Stock reserved for issuance under the Plan; (3) the expiration of the Plan; or
(4) the first meeting of stockholders at which Directors are to be elected that
occurs after the close of the third calendar year following the calendar year in
which occurred the first registration of an equity security under Section 12 of
the Exchange Act; or (ii) such other date required by Section 162(m) of the Code
and the rules and regulations promulgated thereunder.

     (d)  Consultants.

          (i)    Prior to the Listing Date, a Consultant shall not be eligible
for the grant of a Stock Award if, at the time of grant, either the offer or the
sale of the Company's securities to such Consultant is not exempt under Rule 701
of the Securities Act ("Rule 701") because of the nature of the services that
the Consultant is providing to the Company, or because the Consultant is not a
natural person, or as otherwise provided by Rule 701, unless the Company
determines that such grant need not comply with the requirements of Rule 701 and
will satisfy another exemption under the Securities Act as well as comply with
the securities laws of all other relevant jurisdictions.

          (ii)   From and after the Listing Date, a Consultant shall not be
eligible for the grant of a Stock Award if, at the time of grant, a Form S-8
Registration Statement under the Securities Act ("Form S-8") is not available to
register either the offer or the sale of the Company's securities to such
Consultant because of the nature of the services that the Consultant is
providing to the Company, or because the Consultant is not a natural person, or
as otherwise provided by the rules governing the use of Form S-8, unless the
Company determines both (i) that such grant (A) shall be registered in another
manner under the Securities Act (e.g., on a Form S-3 Registration Statement) or
(B) does not require registration under the Securities Act in order to comply
with the requirements of the Securities Act, if applicable, and (ii) that such
grant complies with the securities laws of all other relevant jurisdictions.

          (iii)  Rule 701 and Form S-8 generally are available to consultants
and advisors only if (1) they are natural persons; (2) they provide bona fide
services to the issuer, its parents, its majority-owned subsidiaries or (for
Rule 701 purposes only) majority-owned subsidiaries of the issuer's parent; and
(3) the services are not in connection with the offer or sale of securities in a
capital-raising transaction, and do not directly or indirectly promote or
maintain a market for the issuer's securities.

6.   Option Provisions.

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate.  All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and, if certificates are issued, a separate certificate or certificates
will be issued for shares of Common Stock purchased on exercise of each type of
Option.  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:

     (a)  Term. Subject to the provisions of subsection 5(b) regarding Ten
Percent Stockholders, no Option granted prior to the Listing Date shall be
exercisable after the expiration of ten (10) years from the date it was granted,
and no Incentive Stock Option granted on or after the Listing Date shall be
exercisable after the expiration of ten (10) years from the date it was granted.

     (b)  Exercise Price of an Incentive Stock Option. Subject to the provisions
of subsection 5(b) regarding Ten Percent Stockholders, the exercise price of
each Incentive Stock Option shall be not less than one hundred percent (100%) of
the Fair Market Value of the Common Stock subject to the Option on the date the
Option is granted. Notwithstanding the foregoing, an Incentive 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)  Exercise Price of a Nonstatutory Stock Option. Subject to the
provisions of subsection 5(b) regarding Ten Percent Stockholders, the exercise
price of each Nonstatutory Stock Option granted prior to the Listing Date shall
be not less than eighty-five percent (85%) of the Fair Market Value of the
Common Stock subject to the Option on the date the Option is granted. The
exercise price of each Nonstatutory Stock Option granted on or after the Listing
Date shall be not less than eighty-five percent (85%) of the Fair Market Value
of the Common Stock subject to the Option on the date the Option is granted.
Notwithstanding the foregoing, 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.

     (d)  Consideration. The purchase price of Common 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 at the time of the grant of the Option (or
subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the
Company of other Common Stock, (2) according to a deferred payment or other
similar arrangement with the Optionholder or (3) in any other form of legal
consideration that may be acceptable to the Board. Unless otherwise specifically
provided in the Option, the purchase price of Common Stock acquired pursuant to
an Option that is paid by delivery to the Company of other Common Stock
acquired, directly or indirectly from the Company, shall be paid only by shares
of the Common Stock of the Company that have been held for more than six (6)
months

                                       9
<PAGE>

(or such longer or shorter period of time required to avoid a charge to earnings
for financial accounting purposes). At any time that the Company is incorporated
in Delaware, payment of the Common Stock's "par value," as defined in the
Delaware General Corporation Law, shall not be made by deferred payment.

     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.

     (e)  Transferability of an Incentive Stock Option. An Incentive Stock
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 Optionholder
only by the Optionholder. Notwithstanding the foregoing, the Optionholder 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
Optionholder, shall thereafter be entitled to exercise the Option.

     (f)  Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock
Option granted prior to the Listing Date shall not be transferable except by
will or by the laws of descent and distribution and, to the extent provided in
the Option Agreement, to such further extent as permitted by Section
260.140.41(d) of Title 10 of the California Code of Regulations at the time of
the grant of the Option, and shall be exercisable during the lifetime of the
Optionholder only by the Optionholder. A Nonstatutory Stock Option granted on or
after the Listing Date shall be transferable to the extent provided in the
Option Agreement. If the Nonstatutory Stock Option does not provide for
transferability, then the Nonstatutory Stock 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 Optionholder only by the Optionholder.
Notwithstanding the foregoing, the Optionholder 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 Optionholder, shall thereafter be
entitled to exercise the Option.

     (g)  Vesting Generally. The total number of shares of Common Stock subject
to an Option may, but need not, vest and therefore become exercisable in
periodic installments that may, but need not, be equal. 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. The
provisions of this subsection 6(g) are subject to any Option provisions
governing the minimum number of shares of Common Stock as to which an Option may
be exercised.

     (h)  Minimum Vesting Prior to the Listing Date. Notwithstanding the
foregoing subsection 6(g), to the extent that the following restrictions on
vesting are required by Section 260.140.41(f) of Title 10 of the California Code
of Regulations at the time of the grant of the Option, then:

          (i)    Options granted prior to the Listing Date to an Employee who is
not an Officer, Director or Consultant shall provide for vesting of the total
number of shares of

                                      10
<PAGE>

Common Stock at a rate of at least twenty percent (20%) per year over five (5)
years from the date the Option was granted, subject to reasonable conditions
such as continued employment; and

          (ii)  Options granted prior to the Listing Date to Officers, Directors
or Consultants may be made fully exercisable, subject to reasonable conditions
such as continued employment, at any time or during any period established by
the Company.

  (i)     Termination of Continuous Service. In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or
Disability), the Optionholder may exercise his or her Option (to the extent that
the Optionholder was entitled to exercise such Option 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 Optionholder's
Continuous Service (or such longer or shorter period specified in the Option
Agreement, which period shall not be less than thirty (30) days for Options
granted prior to the Listing Date unless such termination is for cause), or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, after termination, the Optionholder does not exercise his or her Option
within the time specified in the Option Agreement, the Option shall terminate.

  (j)     Extension of Termination Date. An Optionholder's Option Agreement may
also provide that if the exercise of the Option following the termination of the
Optionholder's Continuous Service (other than upon the Optionholder's death or
Disability) would be prohibited at any time solely because the issuance of
shares of Common Stock would violate the registration requirements under the
Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in subsection 6(a) or (ii) the
expiration of a period of three (3) months after the termination of the
Optionholder's Continuous Service during which the exercise of the Option would
not be in violation of such registration requirements.

  (k)     Disability of Optionholder. In the event that an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her Option (to the extent that the Optionholder
was entitled to exercise such Option 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 specified in
the Option Agreement, which period shall not be less than six (6) months for
Options granted prior to the Listing Date) or (ii) the expiration of the term of
the Option as set forth in the Option Agreement. If, after termination, the
Optionholder does not exercise his or her Option within the time specified
herein, the Option shall terminate.

  (l)     Death of Optionholder. In the event (i) an Optionholder's Continuous
Service terminates as a result of the Optionholder's death or (ii) the
Optionholder dies within the period (if any) specified in the Option Agreement
after the termination of the Optionholder's Continuous Service for a reason
other than death, then the Option may be exercised (to the extent the
Optionholder was entitled to exercise such Option as of the date of death) by
the Optionholder'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 Optionholder's death

                                      11
<PAGE>

pursuant to subsection 6(e) or 6(f), but only within the period ending on the
earlier of (1) the date eighteen (18) months following the date of death (or
such longer or shorter period specified in the Option Agreement, which period
shall not be less than six (6) months for Options granted prior to the Listing
Date) or (2) the expiration of the term of such Option as set forth in the
Option Agreement. If, after death, the Option is not exercised within the time
specified herein, the Option shall terminate.

  (m)     Early Exercise. The Option may, but need not, include a provision
whereby the Optionholder may elect at any time before the Optionholder's
Continuous Service terminates to exercise the Option as to any part or all of
the shares of Common Stock subject to the Option prior to the full vesting of
the Option. Subject to the "Repurchase Limitation" in subsection 10(h), any
unvested shares of Common Stock so purchased may be subject to a repurchase
option in favor of the Company or to any other restriction the Board determines
to be appropriate. Provided that the "Repurchase Limitation" in subsection 10(h)
is not violated, the Company will not exercise its repurchase option until at
least six (6) months (or such longer or shorter period of time required to avoid
a charge to earnings for financial accounting purposes) have elapsed following
exercise of the Option unless the Board otherwise specifically provides in the
Option.

  (n)     Right of Repurchase. Subject to the "Repurchase Limitation" in
subsection 10(h), 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 of Common Stock acquired by the Optionholder pursuant to the
exercise of the Option. Provided that the "Repurchase Limitation" in subsection
10(h) is not violated, the Company will not exercise its repurchase option until
at least six (6) months (or such longer or shorter period of time required to
avoid a charge to earnings for financial accounting purposes) have elapsed
following exercise of the Option unless the Board otherwise specifically
provides in the Option.

  (o)     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 Optionholder of
the intent to transfer all or any part of the shares of Common Stock received
upon the exercise of the Option. Except as expressly provided in this subsection
6(o), such right of first refusal shall otherwise comply with any applicable
provisions of the Bylaws of the Company.

  (p)     Re-Load Options.

          (i)   Without in any way limiting the authority of the Board to make
or not to make grants of Options hereunder, the Board shall have the authority
(but not an obligation) to include as part of any Option Agreement a provision
entitling the Optionholder to a further Option (a "Re-Load Option") in the event
the Optionholder exercises the Option evidenced by the Option Agreement, in
whole or in part, by surrendering other shares of Common Stock in accordance
with this Plan and the terms and conditions of the Option Agreement. Unless
otherwise specifically provided in the Option, the Optionholder shall not
surrender shares of Common Stock acquired, directly or indirectly from the
Company, unless such shares have been

                                      12
<PAGE>

held for more than six (6) months (or such longer or shorter period of time
required to avoid a charge to earnings for financial accounting purposes).

          (ii)   Any such Re-Load Option shall (1) provide for a number of
shares of Common Stock equal to the number of shares of Common Stock surrendered
as part or all of the exercise price of such Option; (2) have an expiration date
which is the same as the expiration date of the Option the exercise of which
gave rise to such Re-Load Option; and (3) have an exercise price which is equal
to one hundred percent (100%) of the Fair Market Value of the Common Stock
subject to the Re-Load Option on the date of exercise of the original Option.
Notwithstanding the foregoing, a Re-Load Option shall be subject to the same
exercise price and term provisions heretofore described for Options under the
Plan.

          (iii)  Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board may designate at the time of the grant
of the original Option; provided, however, that the designation of any Re-Load
Option as an Incentive Stock Option shall be subject to the one hundred thousand
dollar ($100,000) annual limitation on the exercisability of Incentive Stock
Options described in subsection 10(d) and in Section 422(d) of the Code. There
shall be no Re-Load Options on a Re-Load Option. Any such Re-Load Option shall
be subject to the availability of sufficient shares of Common Stock under
subsection 4(a) and the "Section 162(m) Limitation" on the grants of Options
under subsection 5(c) and shall be subject to such other terms and conditions as
the Board may determine which are not inconsistent with the express provisions
of the Plan regarding the terms of Options.

7.   Provisions of Stock Awards other than Options.

     (a)  Stock Bonus Awards. Each stock bonus agreement shall be in such form
and shall contain such terms and conditions as the Board shall deem appropriate.
The terms and conditions of stock bonus agreements may change from time to time,
and the terms and conditions of separate stock bonus agreements need not be
identical, but each stock bonus agreement shall include (through incorporation
of provisions hereof by reference in the agreement or otherwise) the substance
of each of the following provisions:

          (i)    Consideration. A stock bonus may be awarded in consideration
for past services actually rendered to the Company or an Affiliate for its
benefit.

          (ii)   Vesting. Subject to the "Repurchase Limitation" in subsection
10(h), shares of Common Stock awarded under the stock bonus agreement may, but
need not, be subject to a share repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board.

          (iii)  Termination of Participant's Continuous Service. Subject to the
"Repurchase Limitation" in subsection 10(h), in the event a Participant's
Continuous Service terminates, the Company may reacquire any or all of the
shares of Common Stock held by the Participant which have not vested as of the
date of termination under the terms of the stock bonus agreement.

                                      13
<PAGE>

          (iv)      Transferability. For a stock bonus award made before the
Listing Date, rights to acquire shares of Common Stock under the stock bonus
agreement shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Participant
only by the Participant. For a stock bonus award made on or after the Listing
Date, rights to acquire shares of Common Stock under the stock bonus agreement
shall be transferable by the Participant only upon such terms and conditions as
are set forth in the stock bonus agreement, as the Board shall determine in its
discretion, so long as Common Stock awarded under the stock bonus agreement
remains subject to the terms of the stock bonus agreement.

  (b)     Restricted Stock Awards. Each restricted stock purchase agreement
shall be in such form and shall contain such terms and conditions as the Board
shall deem appropriate. The terms and conditions of the restricted stock
purchase agreements may change from time to time, and the terms and conditions
of separate restricted stock purchase agreements need not be identical, but each
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions:

          (i)       Purchase Price. Subject to the provisions of subsection 5(b)
regarding Ten Percent Stockholders, the purchase price under each restricted
stock purchase agreement shall be such amount as the Board shall determine and
designate in such restricted stock purchase agreement. For restricted stock
awards made prior to the Listing Date, the purchase price shall not be less than
eighty-five percent (85%) of the Common Stock's Fair Market Value on the date
such award is made or at the time the purchase is consummated. For restricted
stock awards made on or after the Listing Date, the purchase price shall not be
less than eighty-five percent (85%) of the Common Stock's Fair Market Value on
the date such award is made or at the time the purchase is consummated.

          (ii)      Consideration. The purchase price of Common Stock acquired
pursuant to the restricted stock purchase agreement shall be paid either: (i) in
cash at the time of purchase; (ii) at the discretion of the Board, according to
a deferred payment or other similar arrangement with the Participant; or (iii)
in any other form of legal consideration that may be acceptable to the Board in
its discretion; provided, however, that at any time that the Company is
incorporated in Delaware, then payment of the Common Stock's "par value," as
defined in the Delaware General Corporation Law, shall not be made by deferred
payment.

          (iii)     Vesting. Subject to the "Repurchase Limitation" in
subsection 10(h), shares of Common Stock acquired under the restricted stock
purchase agreement may, but need not, be subject to a share repurchase option in
favor of the Company in accordance with a vesting schedule to be determined by
the Board.

          (iv)      Termination of Participant's Continuous Service. Subject to
the "Repurchase Limitation" in subsection 10(h), in the event a Participant's
Continuous Service terminates, the Company may repurchase or otherwise reacquire
any or all of the shares of Common Stock held by the Participant which have not
vested as of the date of termination under the terms of the restricted stock
purchase agreement.

          (v)       Transferability. For a restricted stock award made before
the Listing Date, rights to acquire shares of Common Stock under the restricted
stock purchase agreement shall not be transferable except by will or by the laws
of descent and distribution and shall be exercisable during the lifetime of the
Participant only by the Participant. For a restricted stock award made on or
after the Listing Date, rights to acquire shares of Common Stock under the
restricted stock purchase agreement shall be transferable by the Participant
only upon such terms and conditions as are set forth in the restricted stock
purchase agreement, as the Board shall determine in its discretion, so long as
Common Stock awarded under the restricted stock purchase agreement remains
subject to the terms of the restricted stock purchase agreement.

8.   Covenants of the Company.

     (a)  Availability of Shares. During the terms of the Stock Awards, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Stock Awards.

     (b)  Securities Law Compliance.  The Company shall seek to obtain from each
regulatory commission or agency having jurisdiction over the Plan such authority
as may be required to grant Stock Awards and to issue and sell shares of Common
Stock upon exercise of the Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any
such Stock Award.  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 Common Stock
under the Plan, the Company shall be relieved from any liability for failure to
issue and sell Common Stock upon exercise of such Stock Awards unless and until
such authority is obtained.

9.   Use of Proceeds from Stock.

     Proceeds from the sale of Common Stock pursuant to Stock Awards shall
constitute general funds of the Company.

10.  Miscellaneous.

     (a)  Acceleration of Exercisability and Vesting. The Board shall have the
power to accelerate the time at which a Stock Award may first be exercised or
the time during which a Stock Award or any part thereof will vest in accordance
with the Plan, notwithstanding the provisions in the Stock Award stating the
time at which it may first be exercised or the time during which it will vest.

     (b)  Stockholder Rights. No Participant shall be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares of
Common Stock subject to such Stock Award unless and until such Participant has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.

                                      15
<PAGE>

     (c)  No Employment or other Service Rights. Nothing in the Plan or any
instrument executed or Stock Award granted pursuant thereto shall confer upon
any Participant any right to continue to serve the Company or an Affiliate in
the capacity in effect at the time the Stock Award was granted or shall affect
the right of the Company or an Affiliate to terminate (i) the employment of an
Employee with or without notice and with or without cause, (ii) the service of a
Consultant pursuant to the terms of such Consultant's agreement with the Company
or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the
Company or an Affiliate, and any applicable provisions of the corporate law of
the state in which the Company or the Affiliate is incorporated, as the case may
be.

     (d)  Incentive Stock Option $100,000 Limitation.  To the extent that the
aggregate Fair Market Value (determined at the time of grant) of Common Stock
with respect to which Incentive Stock Options are exercisable for the first time
by any Optionholder 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.

     (e)  Investment Assurances. The Company may require a Participant, as a
condition of exercising or acquiring Common Stock under any Stock Award, (i) to
give written assurances satisfactory to the Company as to the Participant'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 Stock Award; and (ii) to
give written assurances satisfactory to the Company stating that the Participant
is acquiring Common Stock subject to the Stock Award for the Participant's own
account and not with any present intention of selling or otherwise distributing
the Common Stock. The foregoing requirements, and any assurances given pursuant
to such requirements, shall be inoperative if (iii) the issuance of the shares
of Common Stock upon the exercise or acquisition of Common Stock under the Stock
Award has been registered under a then currently effective registration
statement under the Securities Act or (iv) 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
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 Common Stock.

     (f)  Withholding Obligations. To the extent provided by the terms of a
Stock Award Agreement, the Participant may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of Common
Stock under a Stock Award by any of the following means (in addition to the
Company's right to withhold from any compensation paid to the Participant by the
Company) or by a combination of such means: (i) tendering a cash payment; (ii)
authorizing the Company to withhold shares of Common Stock from the shares of
Common Stock otherwise issuable to the Participant as a result of the exercise
or acquisition of Common Stock under the Stock Award, provided, however, that no
shares of Common Stock are

                                      16
<PAGE>

withheld with a value exceeding the minimum amount of tax required to be
withheld by law; or (iii) delivering to the Company owned and unencumbered
shares of Common Stock.

     (g)  Information Obligation. Prior to the Listing Date, to the extent
required by Section 260.140.46 of Title 10 of the California Code of
Regulations, the Company shall deliver financial statements to Participants at
least annually. This subsection 10(g) shall not apply to key Employees whose
duties in connection with the Company assure them access to equivalent
information.

     (h)  Repurchase Limitation. The terms of any repurchase option shall be
specified in the Stock Award and may be either at Fair Market Value at the time
of repurchase or at not less than the original purchase price. To the extent
required by Section 260.140.41 and Section 260.140.42 of Title 10 of the
California Code of Regulations at the time a Stock Award is made, any repurchase
option contained in a Stock Award granted prior to the Listing Date to a person
who is not an Officer, Director or Consultant shall be upon the terms described
below:

          (i)  Fair Market Value. If the repurchase option gives the Company the
right to repurchase the shares of Common Stock upon termination of employment at
not less than the Fair Market Value of the shares of Common Stock to be
purchased on the date of termination of Continuous Service, then (i) the right
to repurchase shall be exercised for cash or cancellation of purchase money
indebtedness for the shares of Common Stock within ninety (90) days of
termination of Continuous Service (or in the case of shares of Common Stock
issued upon exercise of Stock Awards after such date of termination, within
ninety (90) days after the date of the exercise) or such longer period as may be
agreed to by the Company and the Participant (for example, for purposes of
satisfying the requirements of Section 1202(c)(3) of the Code regarding
"qualified small business stock") and (ii) the right terminates when the shares
of Common Stock become publicly traded.

          (ii)  Original Purchase Price. If the repurchase option gives the
Company the right to repurchase the shares of Common Stock upon termination of
Continuous Service at the original purchase price, then (i) the right to
repurchase at the original purchase price shall lapse at the rate of at least
twenty percent (20%) of the shares of Common Stock per year over five (5) years
from the date the Stock Award is granted (without respect to the date the Stock
Award was exercised or became exercisable) and (ii) the right to repurchase
shall be exercised for cash or cancellation of purchase money indebtedness for
the shares of Common Stock within ninety (90) days of termination of Continuous
Service (or in the case of shares of Common Stock issued upon exercise of
Options after such date of termination, within ninety (90) days after the date
of the exercise) or such longer period as may be agreed to by the Company and
the Participant (for example, for purposes of satisfying the requirements of
Section 1202(c)(3) of the Code regarding "qualified small business stock").

11.  Adjustments upon Changes in Stock.

     (a)  Capitalization Adjustments.  If any change is made in the Common Stock
subject to the Plan, or subject to any Stock Award, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock

                                      17
<PAGE>

dividend, dividend in property other than cash, stock 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 class(es) and maximum
number of securities subject to the Plan and available for Incentive Stock
Options pursuant to subsections 4(a) and 4(b) and the maximum number of
securities subject to award to any employee pursuant to subsection 5(c), and the
outstanding Stock Awards will be appropriately adjusted in the class(es) and
number of securities and price per share of Common Stock subject to such
outstanding Stock Awards. The Board shall make such adjustments, and its
determination shall be final, binding and conclusive. (The conversion of any
convertible securities of the Company shall not be treated as a transaction
"without receipt of consideration" by the Company.)

     (b)  Change in Control--Dissolution or Liquidation. In the event of a
dissolution or liquidation of the Company, then all outstanding Stock Awards
shall terminate immediately prior to such event.

     (c)  Change in Control--Asset Sale, Stock Sale, Merger, Consolidation or
Reverse Merger. In the event of (i) a sale, lease or other disposition of all or
substantially all of the assets of the Company, (ii) a sale by the stockholders
of the Company of the voting stock of the Company to another corporation and/or
its subsidiaries that results in the ownership by such corporation and/or its
subsidiaries of fifty percent (50%) or more of the combined voting power of all
classes of the voting stock of the Company entitled to vote; (iii) a merger or
consolidation in which the Company is not the surviving corporation or (iv) a
reverse merger in which the Company is the surviving corporation but the shares
of 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 any surviving corporation or acquiring corporation shall
assume any Stock Awards outstanding under the Plan or shall substitute similar
stock awards (including an award to acquire the same consideration paid to the
stockholders in the transaction described in this subsection 11(c)) for those
outstanding under the Plan. In the event any surviving corporation or acquiring
corporation refuses to assume such Stock Awards or to substitute similar stock
awards for those outstanding under the Plan, then with respect to Stock Awards
held by Participants whose Continuous Service has not terminated, the vesting of
such Stock Awards (and, if applicable, the time during which such Stock Awards
may be exercised) shall be accelerated in full, and the Stock Awards shall
terminate if not exercised (if applicable) at or prior to such event. With
respect to any other Stock Awards outstanding under the Plan, such Stock Awards
shall terminate if not exercised (if applicable) prior to such event.

12.  Amendment of the Plan and Stock Awards.

     (a)  Amendment of Plan. The Board at any time, and from time to time, may
amend the Plan. However, except as provided in Section 11 relating to
adjustments upon changes in Common Stock, no amendment shall be effective unless
approved by the stockholders of the Company to the extent stockholder approval
is necessary to satisfy the requirements of Section 422 of the Code, Rule 16b-3
or any Nasdaq or securities exchange listing requirements.

                                      18
<PAGE>

     (b)  Stockholder Approval. The Board may, in its sole discretion, submit
any other amendment to the Plan for stockholder 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 thereunder regarding the
exclusion of performance-based compensation from the limit on corporate
deductibility of compensation paid to certain executive officers.

     (c)  Contemplated Amendments. It is expressly contemplated that the Board
may amend the Plan in any respect the Board deems necessary or advisable to
provide eligible Employees 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)  No Impairment of Rights. Rights under any Stock Award 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 Participant and (ii) the Participant
consents in writing.

     (e)  Amendment of Stock Awards. The Board at any time, and from time to
time, may amend the terms of any one or more Stock Awards; provided, however,
that the rights under any Stock Award shall not be impaired by any such
amendment unless (i) the Company requests the consent of the Participant and
(ii) the Participant consents in writing.

13.  Termination or Suspension of the Plan.

     (a)  Plan Term. The Board may suspend or terminate the Plan at any time.
Unless sooner terminated, the Plan shall terminate on the day before the tenth
(10th) anniversary of the date the Plan is adopted by the Board or approved by
the stockholders of the Company, whichever is earlier. No Stock Awards may be
granted under the Plan while the Plan is suspended or after it is terminated.

     (b)  No Impairment of Rights. Suspension or termination of the Plan shall
not impair rights and obligations under any Stock Award granted while the Plan
is in effect except with the written consent of the Participant.

14.  Effective Date of Plan.

     The Plan shall become effective on the date the Board adopts the Plan, but
no Stock Award shall be exercised (or, in the case of a stock bonus, shall be
granted) unless and until the Plan has been approved by the stockholders of the
Company, which approval shall be within twelve (12) months before or after the
date the Plan is adopted by the Board.

15.  Choice of Law.

     The law of the State of Delaware shall govern all questions concerning the
construction, validity and interpretation of this Plan, without regard to such
state's conflict of laws rules.
