                            STOCK OPTION AGREEMENT
                            ----------------------

     1.   Grant of Option.  AvantGo, Inc., a Delaware corporation (the
          ---------------
"Company"), hereby grants to ((FullName)) ("Optionee") an option (the "Option")
 -------                                    --------                   ------
to purchase a total number of shares of Common Stock (the "Shares") set forth in
                                                           ------
the Notice of Stock Option Grant, at the exercise price per share set forth in
the Notice of Stock Option Grant (the "Exercise Price") subject to the terms,
                                       --------------
definitions and provisions of the AvantGo, Inc. 1997 Stock Option Plan (the
"Plan") adopted by the Company, which is incorporated herein by reference.
 ----
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings in this Option.

     If designated an Incentive Stock Option, this Option is intended to qualify
as an Incentive Stock Option as defined in Section 422 of the Code.

     2.   Exercise of Option.  This Option shall be exercisable during its Term
          ------------------
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Section 9 of the Plan as follows:

          (a)  Right to Exercise.
               -----------------

               (i)    This Option may be exercised in whole or in part at any
time after the Date of Grant, as to Shares which have not yet vested under the
vesting schedule indicated on the Notice of Stock Option Grant; provided,
                                                                --------
however, that Optionee shall execute as a condition to such exercise of this
-------
Option, the Early Exercise Notice and Restricted Stock Purchase Agreement
attached hereto as Exhibit A (the "Early Exercise Agreement").  If Optionee
                   ---------       ------------------------
chooses to exercise this Option solely as to Shares which have vested under the
vesting schedule indicated on the Notice of Stock Option Grant, Optionee shall
complete and execute the form of Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit B (the "Exercise Agreement").
                             ---------       ------------------
Notwithstanding the foregoing, the Company may in its discretion prescribe or
accept a different form of notice of exercise and/or stock purchase agreement if
such forms are otherwise consistent with this Agreement, the Plan and then-
applicable law.

               (ii)   This Option may not be exercised for a fraction of a
share.

               (iii)  In the event of Optionee's death, disability or other
termination of employment or consulting relationship, the exercisability of the
Option is governed by Sections 5, 6 and 7 below, subject to the limitation
contained in Section 2(a)(iv) below.

               (iv)   In no event may this Option be exercised after the
Expiration Date of this Option as set forth in the Notice of Stock Option Grant.

                                      -3-
<PAGE>

          (b)  Method of Exercise.  This Option shall be exercisable by
               ------------------
execution and delivery of the Early Exercise Agreement or the Exercise
Agreement, whichever is applicable, or of any other written notice approved for
such purpose by the Company which shall state the election to exercise the
Option, the number of Shares in respect of which the Option is being exercised,
and such other representations and agreements as to the holder's investment
intent with respect to such shares of Common Stock as may be required by the
Company pursuant to the provisions of the Plan. Such written notice shall be
signed by Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company. The written notice shall be accompanied by payment of
the Exercise Price. This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

     No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of
applicable law, including the requirements of any stock exchange upon which the
Shares may then be listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

     3.   Method of Payment.  Payment of the Exercise Price shall be by any of
          -----------------
the following, or a combination thereof, at the election of Optionee:

          (a)  cash;

          (b)  check;

          (c)  surrender of other shares of Common Stock of the Company which
(i) in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by Optionee for more than 6 months on the date of surrender, and
(ii) have a Fair Market Value on the date of surrender equal to the Exercise
Price of the Shares as to which the Option is being exercised; or

          (d)  if there is a public market for the Shares and they are
registered under the Securities Exchange Act of 1934, as amended (the "Exchange
                                                                       --------
Act"), delivery of a properly executed exercise notice together with
---
irrevocable instructions to a broker to deliver promptly to the Company the
amount of sale or loan proceeds required to pay the Exercise Price.

     4.   Restrictions on Exercise.  This Option may not be exercised until such
          ------------------------
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

                                      -2-

     5.   Termination of Relationship.  In the event of termination of
          ---------------------------
Optionee's Continuous Status as an Employee or Consultant, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
                                                                   -----------
Date"), exercise this Option during the Termination Period set forth in the
----
Notice of Stock Option Grant. To the extent that Optionee was not entitled to
exercise this Option at such Termination Date, or if Optionee does not exercise
this Option within the Termination Period, the Option shall terminate.

     6.   Disability of Optionee.
          ----------------------

          (a)  Notwithstanding the provisions of Section 5 above, in the event
of termination of Optionee's Continuous Status as an Employee or Consultant 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 months from the
Termination Date (but in no event later than the Expiration Date set forth in
the Notice of Stock Option Grant and in Section 9 below), exercise this Option
to the extent he or she was entitled to exercise it at such Termination Date. To
the extent that Optionee was not entitled to exercise the Option on the
Termination Date, or if Optionee does not exercise such Option to the extent so
entitled within the time specified in this Section 6(a), the Option shall
terminate.

          (b)  Notwithstanding the provisions of Section 5 above, in the event
of termination of Optionee's consulting relationship or Continuous Status as an
Employee as a result of a disability not constituting a total and permanent
disability (as set forth in Section 22(e)(3) of the Code), Optionee may, but
only within six months from the Termination Date (but in no event later than the
Expiration Date set forth in the Notice of Stock Option Grant and in Section 9
below), exercise the Option to the extent Optionee was entitled to exercise it
as of such Termination Date; provided, however, that if this is an Incentive
Stock Option and Optionee fails to exercise this Incentive Stock Option within
three months from the Termination Date, this Option will cease to qualify as an
Incentive Stock Option (as defined in Section 422 of the Code) and Optionee will
be treated for federal income tax purposes as having received ordinary income at
the time of such exercise in an amount generally measured by the difference
between the Exercise Price for the Shares and the Fair Market Value of the
Shares on the date of exercise. To the extent that Optionee was not entitled to
exercise the Option at the Termination Date, or if Optionee does not exercise
such Option to the extent so entitled within the time specified in this Section
6(b), the Option shall terminate.

     7.   Death of Optionee.  In the event of the death of Optionee (a) during
          -----------------
the Term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Status as an Employee or Consultant since the date of
grant of the Option, or (b) within 30 days after Optionee's Termination Date,
the Option may be exercised at any time within six months following the date of
death (but in no event later than the Expiration Date set forth in the Notice of
Stock Option Grant and in Section 9 below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent of the right to exercise that had accrued at the Termination
Date.

                                      -3-
<PAGE>

     8.   Non-Transferability of Option.  This Option may not be transferred in
          -----------------------------
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by him or her.  The terms
of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of Optionee.

     9.   Term of Option.  This Option may be exercised only within the Term set
          --------------
forth in the Notice of Stock Option Grant, subject to the limitations set forth
in Section 7 of the Plan.

     10.  Tax Consequences.  Set forth below is a brief summary as of the date
          ----------------
of this Option of certain of the federal and California tax consequences of
exercise of this Option and disposition of the Shares under the laws in effect
as of the Date of Grant.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX
LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  Exercise of Incentive Stock Option.  If this Option qualifies as
               ----------------------------------
an Incentive Stock Option, there will be no regular federal or California income
tax liability upon the exercise of the Option, although the excess, if any, of
the Fair Market Value of the Shares on the date of exercise over the Exercise
Price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject Optionee to the alternative minimum tax in
the year of exercise.

          (b)  Exercise of Nonstatutory Stock Option.  If this Option does not
               -------------------------------------
qualify as an Incentive Stock Option, there may be a regular federal income tax
liability and a California income tax liability upon the exercise of the Option.
Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the Fair Market Value
of the Shares on the date of exercise over the Exercise Price.  If Optionee is
an employee, the Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

          (c)  Disposition of Shares.  In the case of a Nonstatutory Stock
               ---------------------
Option, if Shares are held for at least one year, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
and California income tax purposes.  In the case of an Incentive Stock Option,
if Shares transferred pursuant to the Option are held for at least one year
after exercise and are disposed of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal and California income tax purposes.  In either case,
the long-term capital gain will be taxed for federal income tax and alternative
minimum tax purposes at a maximum rate of 28% if the Shares are held more than
one year but less than 18 months after exercise and at 20% if the Shares are
held more than 18 months after exercise.  If Shares purchased under an Incentive
Stock Option are disposed of within one year after exercise or within two years
after the Date of Grant, any gain realized on such disposition will be treated
as compensation income (taxable at ordinary income rates) to the extent of the
difference between the Exercise Price and the lesser of (i) the Fair Market
Value of the Shares on the date of exercise, or (ii) the sale price of the
Shares.

          (d)  Notice of Disqualifying Disposition of Incentive Stock Option
               -------------------------------------------------------------
Shares.  If the Option granted to Optionee herein is an Incentive Stock Option,
------
and if Optionee sells or otherwise disposes of any of the Shares acquired
pursuant to the Incentive Stock Option on or before the later of (i) the date
two years after the Date of Grant, or (ii) the date one year after the date of
exercise, Optionee shall immediately notify the Company in writing of such
disposition.  Optionee acknowledges and agrees that he or she may be subject to
income tax withholding by the Company on the compensation income recognized by
Optionee from the early disposition by payment in cash or out of the current
earnings paid to Optionee.

     11.  Withholding Tax Obligations.  Optionee understands that, upon
          ---------------------------
exercising a Nonstatutory Stock Option, he or she will recognize income for tax
purposes in an amount equal to the excess of the then Fair Market Value of the
Shares over the Exercise Price.  However, the timing of this income recognition
may be deferred for up to six months if Optionee is subject to Section 16 of the
Exchange Act.  If Optionee is an employee, the Company will be required to
withhold from Optionee's compensation, or collect from Optionee and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income.  Additionally, Optionee may at some point be required to
satisfy tax withholding obligations with respect to the disqualifying
disposition of an Incentive Stock Option.  Optionee shall satisfy his or her tax
withholding obligation arising upon the exercise of this Option by one or some
combination of the following methods:  (a) by cash payment, (b) out of
Optionee's current compensation, (c) if permitted by the Administrator, in its
discretion, by surrendering to the Company Shares which (i) in the case of
Shares previously acquired from the Company, have been owned by Optionee for
more than six months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to or greater than Optionee's marginal tax rate
times the ordinary income recognized, or (d) by electing to have the Company
withhold from the Shares to be issued upon exercise of the Option that number of
Shares having a Fair Market Value equal to the amount required to be withheld.
For this purpose, 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
(the "Tax Date").
      --------

     If Optionee is subject to Section 16 of the Exchange Act (an "Insider"),
                                                                   -------
any surrender of previously owned Shares to satisfy tax withholding obligations
arising upon exercise of this Option must comply with the applicable provisions
of Rule 16b-3 promulgated under the Exchange Act ("Rule 16b-3").
                                                   ----------

     All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

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

          (b)  once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made; and

          (c)  all elections shall be subject to the consent or disapproval of
the Administrator.

     12.  Market Standoff Agreement.  In connection with the initial public
          -------------------------
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Optionee hereby agrees not to sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any Shares (other than those
included in the registration) without the prior written consent of the Company
or such underwriters, as the case may be, for such period of time (not to exceed
180 days) from the effective date of such registration as may be requested by
the Company or such managing underwriters and to execute an agreement reflecting
the foregoing as may be requested by the underwriters at the time of the
Company's initial public offering.

TERMINATE OPTIONEE'S EMPLOYMENT OR CONSULTANCY AT ANY TIME, WITH OR WITHOUT
CAUSE.

or she is familiar with the terms and provisions thereof, and hereby accepts

                                            -------
("Purchaser").  To the extent any capitalized terms used in this Agreement are
  ----------
not defined, they shall have the meaning ascribed to them in the 1997 Stock
Option Plan.

     1.   Exercise of Option.  Subject to the terms and conditions hereof,
          ------------------
Purchaser hereby elects to exercise his or her option to purchase ((NoShares))
shares of the Common Stock (the "Shares") of the Company under and pursuant to
                                 ------
the Company's 1997 Stock Option Plan (the "Plan") and the Stock Option Agreement
                                           ----
dated ______________ (the "Option Agreement").  Of these Shares, Purchaser has
                           ----------------
elected to purchase _______________ of those Shares which have become vested as
of the date hereof under the Vesting Schedule set forth in the Notice of Stock
Option Grant (the "Vested Shares") and _____________ Shares which have not yet
                   -------------
vested under such Vesting Schedule (the "Unvested Shares"). The purchase price
                                         --------------
Purchaser for the Shares shall be ((OptionPrice)) per Share for a total
purchase price of ((TotalExercisePrice)).  The term "Shares" refers to the
                                                     ------
purchased Shares and all securities received in replacement of the Shares or as
stock dividends or splits, all securities received in replacement of the Shares
in a recapitalization, merger, reorganization, exchange or the like, and all
new, substituted or additional securities or other properties to which Purchaser
is entitled by reason of Purchaser's ownership of the Shares.

     2.   Time and Place of Exercise.  The purchase and sale of the Shares under
          --------------------------
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement. On such date, the Company
will deliver to Purchaser a certificate representing the Shares to be purchased
by Purchaser (which shall be issued in Purchaser's name) against payment of the
purchase price therefor by Purchaser by (a) check made payable to the Company,
(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, or (d) a combination of the foregoing.

     3.   Limitations on Transfer.  In addition to any other limitation on
          -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below), except as provided below.
After any Shares have been released from such Repurchase Option, Purchaser shall
not assign, encumber or dispose of any interest in such Shares except in
compliance with the provisions below and applicable securities laws.
<PAGE>

          (a)  Repurchase Option.
               -----------------

               (i)    In the event of the voluntary or involuntary termination
of Purchaser's employment or consulting relationship with the Company for any
reason (including death or disability), with or without cause, the Company shall
upon the date of such termination (the "Termination Date") have an irrevocable,
                                        ----------------
exclusive option (the "Repurchase Option") for a period of 60 days from such
                       -----------------
date to repurchase all or any portion of the Unvested Shares held by Purchaser
as of the Termination Date which have not yet been released from the Company's
Repurchase Option at the original purchase price per Share specified in Section
1 (adjusted for any stock splits, stock dividends and the like).

               (ii)   The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option.  The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant until all Shares are released from the
Repurchase Option.  Fractional shares shall be rounded to the nearest whole
share.

          (b)  Right of First Refusal.  Before any Shares held by Purchaser or
               ----------------------
any transferee of Purchaser (either being sometimes referred to herein as the

"Holder") may be sold or otherwise transferred (including transfer by gift or
 ------
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(b) (the "Right of First Refusal").
                   ----------------------

               (i)    Notice of Proposed Transfer. The Holder of the Shares
                      ---------------------------
shall deliver to the Company a written notice (the "Notice") stating: (i) the
                                                    ------
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the
name of each proposed purchaser or other transferee ("Proposed Transferee");
                                                      -------------------
(iii) the number of Shares to be transferred to each Proposed Transferee; and
(iv) the terms and conditions of each proposed sale or transfer.  The Holder
shall offer the Shares at the same price (the "Offered Price") and upon the same
                                               -------------
terms (or terms as similar as reasonably possible) to the Company or its
assignee(s).

                                      -2-
<PAGE>

               (ii)   Exercise of Right of First Refusal.  At any time within
                      ----------------------------------
30 days after receipt of the Notice, the Company and/or its assignee(s) may, by
giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection
(iii) below.

               (iii)  Purchase Price.  The purchase price ("Purchase Price")
                      --------------                        --------------
for the Shares purchased by the Company or its assignee(s) under this Section
3(b) shall be the Offered Price. If the Offered Price includes consideration
other than cash, the cash equivalent value of the non-cash consideration shall
be determined by the Board of Directors of the Company in good faith.

               (iv)   Payment.  Payment of the Purchase Price shall be made, at
                      -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

               (v)    Holder's Right to Transfer.  If all of the Shares proposed
                      --------------------------
in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section 3(b), then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided
further that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

               (vi)   Exception for Certain Family Transfers.  Anything to the
                      --------------------------------------
contrary contained in this Section 3(b) notwithstanding, the transfer of any or
all of the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family (as defined below) or a trust for the
benefit of Purchaser's Immediate Family shall be exempt from the provisions of
this Section 3(b). "Immediate Family" as used herein shall mean spouse, lineal
                    ----------------
descendant or antecedent, father, mother, brother or sister.  In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section, and there shall be no further
transfer of such Shares except in accordance with the terms of this Section 3.

                                      -3-
<PAGE>

          (c)  Involuntary Transfer.
               --------------------

               (i)    Company's Right to Purchase upon Involuntary Transfer.
                      -----------------------------------------------------
In the event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including death or divorce, but
excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above)
of all or a portion of the Shares by the record holder thereof, the Company
shall have an option to purchase all of the Shares transferred at the greater of
the purchase price paid by Purchaser pursuant to this Agreement or the Fair
Market Value of the Shares on the date of transfer.  Upon such a transfer, the
person acquiring the Shares shall promptly notify the Secretary of the Company
of such transfer.  The right to purchase such Shares shall be provided to the
Company for a period of 30 days following receipt by the Company of written
notice by the person acquiring the Shares.

               (ii)   Price for Involuntary Transfer.  With respect to any stock
                      ------------------------------
to be transferred pursuant to Section 3(c)(i), the price per Share shall be a
price set by the Board of Directors of the Company that will reflect the current
value of the stock in terms of present earnings and future prospects of the
Company. The Company shall notify Purchaser or his or her executor of the price
so determined within 30 days after receipt by it of written notice of the
transfer or proposed transfer of Shares. However, if the Purchaser does not
agree with the valuation as determined by the Board of Directors of the Company,
the Purchaser shall be entitled to have the valuation determined by an
independent appraiser to be mutually agreed upon by the Company and the
Purchaser and whose fees shall be borne equally by the Company and the
Purchaser.

          (d)  Assignment.  The right of the Company to purchase any part of the
               ----------
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations; provided, however, that an
assignee, other than a corporation that is the Parent or a 100% owned Subsidiary
of the Company, must pay the Company, upon assignment of such right, cash equal
to the difference between the original purchase price and Fair Market Value, if
the original purchase price is less than the Fair Market Value of the Shares
subject to the assignment.

          (e)  Restrictions Binding on Transferees.  All transferees of Shares
               -----------------------------------
or any interest therein will receive and hold such Shares or interest subject to
the provisions of this Agreement, including, insofar as applicable, the
Company's option to repurchase under Section 3(a).  Any sale or transfer of the
Company's Shares shall be void unless the provisions of this Agreement are
satisfied.

          (f)  Termination of Rights.  The Right of First Refusal granted the
               ---------------------
Company by Section 3(b) above and the option to repurchase the Shares in the
event of an involuntary transfer granted the Company by Section 3(c) above shall
terminate upon the first sale of Common Stock of the Company to the general
public pursuant to a registration statement filed with and declared effective by
the Securities and Exchange Commission under the Securities Act of 1933, as
amended (the "Securities Act").  Upon termination of the Right of First Refusal
              --------------
described in Section 3(b) and the expiration or exercise of the Company's
repurchase option described in Section 3(a) above, a new certificate or
certificates representing the Shares not

                                      -4-
<PAGE>

repurchased shall be issued, on request, without the legend referred to in
Section 6(a)(ii) herein and delivered to Purchaser.

     4.   Escrow of Unvested Shares.  For purposes of facilitating the
          -------------------------
enforcement of the provisions of Section 3 above, Purchaser agrees, immediately
upon receipt of the certificate(s) for the Shares subject to the Company's
Repurchase Option described in Section 3(a), to deliver such certificate(s),
together with an Assignment Separate from Certificate in the form attached to
this Agreement as Attachment A executed by Purchaser and by Purchaser's spouse
                  ------------
(if required for transfer), in blank, to the Secretary of the Company, or the
Secretary's designee, to hold such certificate(s) and Assignment Separate from
Certificate in escrow and to take all such actions and to effectuate all such
transfers and/or releases as are in accordance with the terms of this Agreement.
Purchaser hereby acknowledges that the Secretary of the Company, or the
Secretary's designee, is so appointed as the escrow holder with the foregoing
authorities as a material inducement to make this Agreement and that said
appointment is coupled with an interest and is accordingly irrevocable.
Purchaser agrees that said escrow holder shall not be liable to any party hereof
(or to any other party).  The escrow holder may rely upon any letter, notice or
other document executed by any signature purported to be genuine and may resign
at any time.  Purchaser agrees that if the Secretary of the Company, or the
Secretary's designee, resigns as escrow holder for any or no reason, the Board
of Directors of the Company shall have the power to appoint a successor to serve
as escrow holder pursuant to the terms of this Agreement.

     5.   Investment and Taxation Representations.  In connection with the
          ---------------------------------------
purchase of the Shares, Purchaser represents to the Company the following:

          (a)  Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the securities.
Purchaser is purchasing these securities for investment for his or her own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act.

          (b)  Purchaser understands that the securities have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of
Purchaser's investment intent as expressed herein.

          (c)  Purchaser understands that the Shares are "restricted securities"
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, Purchaser must hold the Shares indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale.  Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

                                      -5-
<PAGE>

          (d)  Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

     6.   Restrictive Legends and Stop-Transfer Orders.
          --------------------------------------------

          (a)  Legends.  The certificate or certificates representing the Shares
               -------
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

               (i)    THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                      REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
                      ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
                      CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH
                      SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE
                      REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF
                      COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
                      REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
                      1933.

               (ii)   THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
                      TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
                      AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY
                      OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

          (b)  Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
               ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

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

                                      -6-
<PAGE>

     7.   No Employment Rights.  Nothing in this Agreement shall affect in any
          --------------------
manner whatsoever the right or power of the Company, or a Parent or Subsidiary
of the Company, to terminate Purchaser's employment or consulting relationship,
for any reason, with or without cause.

     8.   Section 83(b) Election.  Purchaser understands that Section 83(a) of
          ----------------------
the Internal Revenue Code of 1986, as amended (the "Code"), taxes as ordinary
                                                    ----
income for a Nonstatutory Stock Option and as alternative minimum taxable income
for an Incentive Stock Option the difference between the amount paid for the
Shares and the Fair Market Value of the Shares as of the date any restrictions
on the Shares lapse.  In this context, "restriction" means the right of the
                                        -----------
Company to buy back the Shares pursuant to the Repurchase Option set forth in
Section 3(a) of this Agreement.  Purchaser understands that Purchaser may elect
to be taxed at the time the Shares are purchased, rather than when and as the
Repurchase Option expires, by filing an election under Section 83(b) (an "83(b)
                                                                          -----
Election") of the Code with the Internal Revenue Service within 30 days from the
--------
date of purchase.  Even if the Fair Market Value of the Shares at the time of
the execution of this Agreement equals the amount paid for the Shares, the
election must be made to avoid income and alternative minimum tax treatment
under Section 83(a) in the future.  Purchaser understands that failure to file
such an election in a timely manner may result in adverse tax consequences for
Purchaser.  Purchaser further understands that an additional copy of such
election form should be filed with his or her federal income tax return for the
calendar year in which the date of this Agreement falls.  Purchaser acknowledges
that the foregoing is only a summary of the effect of United States federal
income taxation with respect to purchase of the Shares hereunder, and does not
purport to be complete.  Purchaser further acknowledges that the Company has
directed Purchaser to seek independent advice regarding the applicable
provisions of the Code, the income tax laws of any municipality, state or
foreign country in which Purchaser may reside, and the tax consequences of
Purchaser's death.

     Purchaser agrees that he or she will execute and deliver to the Company
with this executed Agreement a copy of the Acknowledgment and Statement of
Decision Regarding Section 83(b) Election (the "Acknowledgment") attached hereto
                                                --------------
as Attachment B.  Purchaser further agrees that he or she will execute and
   ------------
submit with the Acknowledgment a copy of the 83(b) Election attached hereto as

Attachment C (for income tax purposes in connection with the early exercise of a
------------
Nonstatutory Stock Option) or Attachment D (for alternative minimum tax purposes
                              ------------
in connection with the early exercise of an incentive stock option) if Purchaser
has indicated in the Acknowledgment his or her decision to make such an
election.

     9.   Market Stand-off Agreement.  In connection with the initial public
          --------------------------
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Shares (other than those included
in the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
Company or such managing underwriters and to execute an agreement reflecting the
foregoing as may be requested by the underwriters at the time of the Company's
initial public offering.

Agreement may only be assigned with the prior written consent of the Company.

                                 AVANTCO, INC.

                             1997 STOCK OPTION PLAN

         EARLY EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT
         -------------------------------------------------------------

   This Agreement ("Agreement") is made as of _______________, by and between
                    ---------
AvantGo, Inc., a Delaware corporation (the "Company"), and ((Full Name))
("Purchaser"). To the extent any capitalized terms used in this Agreement are
  ---------
not defined, they shall have the meaning ascribed to them in the 1997 Stock
Option Plan.

   1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser
hereby elects to exercise his or her option to purchase ((NoShares)) shares of
the Common Stock (the "Shares") of the Company under and pursuant to the
                       ------
Company's 1997 Stock Option Plan (the "Plan") and the Stock Option Agreement
                                       ----
dated   ________. (the "Option Agreement"). Of these Shares, Purchaser has
                        ----------------
elected to purchase _____________ of those Shares which have become vested as of
the date hereof under the Vesting Schedule set forth in the Notice of Stock
Option Grant (the "Vested Shares") and _____ Shares which have not yet vested
                   -------------
under such Vesting Schedule (the "Unvested Shares"). The purchase price for the
                                  ----------------
Shares shall be ((OptionPrice)) per Share for a total purchase price of
((TotalExercisePrice)). The term "Shares" refers to the purchased Shares and all
                                  ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

   2. Time and Place of Exercise. The purchase and sale of the Shares under
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement. On such date, the Company
will deliver to Purchaser a certificate representing the Shares to be purchased
by Purchaser (which shall be issued in Purchaser's name) against payment of the
purchase price therefor by Purchaser by (a) check made payable to the Company,
(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, or (d) a combination of the foregoing.

   3. Limitations on Transfer. In addition to any other limitation on transfer
created by applicable securities laws, Purchaser shall not assign, encumber or
dispose of any interest in the Shares while the Shares are subject to the
Company's Repurchase Option (as defined below), except as provided below. After
any Shares have been released from such Repurchase Option, Purchaser shall not
assign, encumber or dispose of any interest in such Shares except in compliance
with the provisions below and applicable securities laws.
<PAGE>

     (a)  Repurchase Option.

          (i)    In the event of the voluntary or involuntary termination of
Purchaser's employment or consulting relationship with the Company for any
reason (including death or disability), with or without cause, the Company shall
upon the date of such termination (the "Termination Date") have an irrevocable,
                                        ----------------
exclusive option (the "Repurchase Option") for a period of 60 days from such
                       -----------------
date to repurchase all or any portion of the Unvested Shares held by Purchaser
as of the Termination Date which have not yet been released from the Company's
Repurchase Option at the original purchase price per Share specified in Section
1 (adjusted for any stock splits, stock dividends and the like).

          (ii)   The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

          (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option. The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant until all Shares are released from the
Repurchase Option. Fractional shares shall be rounded to the nearest whole
share.

     (b)  Right of First Refusal. Before any Shares held by Purchaser or any
transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
 ------
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(b) (the "Right of First Refusal").
                   ----------------------

          (i) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
                                              ------
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
                                              -------------------
number of Shares to be transferred to each Proposed Transferee; and (iv) the
terms and conditions of each proposed sale or transfer. The Holder shall offer
the Shares at the same price (the "Offered Price") and upon the same terms (or
                                   -------------
terms as similar as reasonably possible) to the Company or its assignee(s).

                                      -2-
<PAGE>

          (ii) Exercise of Right of First Refusal. At any time within 30 days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving
written notice to the Holder, elect to purchase all, but not less than all,
of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection
(iii) below.

          (iii) Purchase Price. The purchase price ("Purchase Price") for the
                                                     --------------
Shares purchased by the Company or its assignee(s) under this Section 3(b) shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

          (iv) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

          (v) Holder's Right to Transfer. If all of the Shares proposed in the
Notice to be transferred to a given Proposed Transferee are not purchased by the
Company and/or its assignee(s) as provided in this Section 3(b), then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within 60 days after the date of the Notice and provided further
that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

          (vi) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section 3(b) notwithstanding, the transfer of any or all of
the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family (as defined below) or a trust for the
benefit of Purchaser's Immediate Family shall be exempt from the provisions of
this Section 3(b). "Immediate Family" as used herein shall mean spouse, lineal
                    ----------------
descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section, and there shall be no further
transfer of such Shares except in accordance with the terms ofthis Section 3.

                                      -3-
<PAGE>

     (c)  Involuntary Transfer.

          (i) Company's Right to Purchase upon Involuntary Transfer. In the
event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including death or divorce, but
excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above)
of all or a portion of the Shares by the record holder thereof, the Company
shall have an option to purchase all of the Shares transferred at the greater of
the purchase price paid by Purchaser pursuant to this Agreement or the Fair
Market Value of the Shares on the date of transfer. Upon such a transfer, the
person acquiring the Shares shall promptly notify the Secretary of the Company
of such transfer. The right to purchase such Shares shall be provided to the
Company for a period of 30 days following receipt by the Company of written
notice by the person acquiring the Shares.

          (ii) Price for Involuntary Transfer. With respect to any stock to be
transferred pursuant to Section 3(c)(i), the price per Share shall be a price
set by the Board of Directors of the Company that will reflect the current value
of the stock in terms of present earnings and future prospects of the Company.
The Company shall notify Purchaser or his or her executor of the price so
determined within 30 days after receipt by it of written notice of the transfer
or proposed transfer of Shares. However, if the Purchaser does not agree with
the valuation as determined by the Board of Directors of the Company, the
Purchaser shall be entitled to have the valuation determined by an independent
appraiser to be mutually agreed upon by the Company and the Purchaser and whose
fees shall be borne equally by the Company and the Purchaser.

       (d) Assignment. The right of the Company to purchase any part of the
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations; provided, however, that an
assignee, other than a corporation that is the Parent or a 100% owned Subsidiary
of the Company, must pay the Company, upon assignment of such right, cash equal
to the difference between the original purchase price and Fair Market Value, if
the original purchase price is less than the Fair Market Value of the Shares
subject to the assignment.

       (e) Restrictions Binding on Transferees. All transferees of Shares or any
interest therein will receive and hold such Shares or interest subject to the
provisions of this Agreement, including, insofar as applicable, the Company's
option to repurchase under Section 3(a). Any sale or transfer of the Company's
Shares shall be void unless the provisions of this Agreement are satisfied.

       (f) Termination of Rights. The Right of First Refusal granted the Company
by Section 3(b) above and the option to repurchase the Shares in the event of an
involuntary transfer granted the Company by Section 3(c) above shall terminate
upon the first sale of Common Stock of the Company to the general public
pursuant to a registration statement filed with and declared effective by the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Securities Act"). Upon termination of the Right of First Refusal described
      --------------
in Section 3(b) and the expiration or exercise of the Company's repurchase
option described in Section 3(a) above, a new certificate or certificates
representing the Shares not

                                      -4-
<PAGE>

repurchased shall be issued, on request, without the legend referred to in
Section 6(a)(ii) herein and delivered to Purchaser.

     4.   Escrow of Unvested Shares. For purposes of facilitating the
enforcement of the provisions of Section 3 above, Purchaser agrees, immediately
upon receipt of the certificate(s) for the Shares subject to the Company's
Repurchase Option described in Section 3(a), to deliver such certificate(s),
together with an Assignment Separate from Certificate in the form attached to
this Agreement as Attachment A executed by Purchaser and by Purchaser's spouse
                  ------------
(if required for transfer), in blank, to the Secretary of the Company, or the
Secretary's designee, to hold such certificate(s) and Assignment Separate from
Certificate in escrow and to take all such actions and to effectuate all such
transfers and/or releases as are in accordance with the terms of this Agreement.
Purchaser hereby acknowledges that the Secretary of the Company, or the
Secretary's designee, is so appointed as the escrow holder with the foregoing
authorities as a material inducement to make this Agreement and that said
appointment is coupled with an interest and is accordingly irrevocable.
Purchaser agrees that said escrow holder shall not be liable to any party hereof
(or to any other party). The escrow holder may rely upon any letter, notice or
other document executed by any signature purported to be genuine and may resign
at any time. Purchaser agrees that if the Secretary of the Company, or the
Secretary's designee, resigns as escrow holder for any or no reason, the Board
of Directors of the Company shall have the power to appoint a successor to serve
as escrow holder pursuant to the terms of this Agreement.

     5.   Investment and Taxation Representations. In connection with the
purchase of the Shares, Purchaser represents to the Company the following:

          (a)  Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the securities.
Purchaser is purchasing these securities for investment for his or her own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act.

          (b)  Purchaser understands that the securities have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of
Purchaser's investment intent as expressed herein.

          (c)  Purchaser understands that the Shares are "restricted securities"
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, Purchaser must hold the Shares indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale. Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

                                      -5-
<PAGE>

          (d)  Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

     6.   Restrictive Legends and Stop-Transfer Orders.

          (a)  Legends. The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

               (i)   THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                     REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
                     ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
                     CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH
                     SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE
                     REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF
                     COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
                     REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
                     1933.

               (ii)  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
                     TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
                     AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY
                     OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

          (b)  Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

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

                                      -6-
<PAGE>

     7.   No Employment Rights. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a Parent or Subsidiary
of the Company, to terminate Purchaser's employment or consulting relationship,
for any reason, with or without cause.

     8.   Section 83(b) Election. Purchaser understands that Section 83(a) of
the Internal Revenue Code of 1986, as amended (the "Code"), taxes as ordinary
                                                    ----
income for a Nonstatutory Stock Option and as alternative minimum taxable income
for an Incentive Stock Option the difference between the amount paid for the
Shares and the Fair Market Value of the Shares as of the date any restrictions
on the Shares lapse. In this context, "restriction" means the right of the
                                       -----------
Company to buy back the Shares pursuant to the Repurchase Option set forth
in Section 3(a) of this Agreement. Purchaser understands that Purchaser may
elect to be taxed at the time the Shares are purchased, rather than when and as
the Repurchase Option expires, by filing an election under Section 83(b)
(an "83(b) Election") of the Code with the Internal Revenue Service within 30
     --------------
days from the date of purchase. Even if the Fair Market Value of the Shares at
the time of the execution of this Agreement equals the amount paid for the
Shares, the election must be made to avoid income and alternative minimum tax
treatment under Section 83(a) in the future. Purchaser understands that failure
to file such an election in a timely manner may result in adverse tax
consequences for Purchaser. Purchaser further understands that an additional
copy of such election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls.
Purchaser acknowledges that the foregoing is only a summary of the effect of
United States federal income taxation with respect to purchase of the Shares
hereunder, and does not purport to be complete. Purchaser further acknowledges
that the Company has directed Purchaser to seek independent advice regarding the
applicable provisions of the Code, the income tax laws of any municipality,
state or foreign country in which Purchaser may reside, and the tax consequences
of Purchaser's death.

     Purchaser agrees that he or she will execute and deliver to the Company
with this executed Agreement a copy of the Acknowledgment and Statement of
Decision Regarding Section 83(b) Election (the "Acknowledgment") attached hereto
                                                --------------
as Attachment B. Purchaser further agrees that he or she will execute and submit
   ------------
with the Acknowledgment a copy of the 83(b) Election attached hereto as
Attachment C (for income tax purposes in connection with the early exercise of a
------------
Nonstatutory Stock Option) or Attachment D (for alternative minimum tax purposes
                              ------------
in connection with the early exercise of an incentive stock option) if Purchaser
has indicated in the Acknowledgment his or her decision to make such an
election.

     9.   Market Stand-off Agreement. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Shares (other than those included
in the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
Company or such managing underwriters and to execute an agreement reflecting the
foregoing as may be requested by the underwriters at the time of the Company's
initial public offering.

Purchaser hereby elects to exercise his or her option to purchase _________
shares of the Common Stock (the "Shares") of the Company under and pursuant to
                                 ------

dated _______ , (the "Option Agreement"). The purchase price for the Shares
                      ----------------
shall be ((Option Price)) per Share for a total purchase price of ((Total
Exercise Price)). The term "Shares" refers to the purchased Shares and all
                            ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

    2.  Time and Place of Exercise. The purchase and sale of the Shares under
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement. On such date, the Company

(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, or (d) a combination of the foregoing.

    3.  Limitations on Transfer. In addition to any other limitation on transfer
created by applicable securities laws, Purchaser shall not assign, encumber or
dispose of any interest in the Shares except in compliance with the provisions
below and applicable securities laws.

        (a) Right of First Refusal. Before any Shares held by Purchaser or any
transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
 ------
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(a) (the "Right of First Refusal").
                   ----------------------

            (i) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
                                              ------
bona fide
<PAGE>

intention to sell or otherwise transfer such Shares; (ii) the name of each
proposed purchaser or other transferee ("Proposed Transferee"); (iii) the number
                                         -------------------
of Shares to be transferred to each Proposed Transferee; and (iv) the terms and
conditions of each proposed sale or transfer. The Holder shall offer the Shares
at the same price (the "Offered Price") and upon the same terms (or terms as
                        -------------
similar as reasonably possible) to the Company or its assignee(s).

          (ii)   Exercise of Right of First Refusal. At any time within 30 days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving
written notice to the Holder, elect to purchase all, but not less than all, of
the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection
(iii) below.

          (iii)  Purchase Price. The purchase price ("Purchase Price") for the
                                                      --------------
Shares purchased by the Company or its assignee(s) under this Section 3(a) shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

          (iv)   Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

          (v)    Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section 3(a), then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided
further that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

          (vi)   Exception for Certain Family Transfers. Anything to the
contrary contained in this Section 3(a) notwithstanding, the transfer of any or
all of the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family (as defined below) or a trust for the

transfer of such Shares except in accordance with the terms of this Section 3.

       (b) Involuntary Transfer.

           (i) Company's Right to Purchase upon Involuntary Transfer. In the
event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including death or divorce, but
excluding a transfer to Immediate Family as set forth in Section 3(a)(vi) above)
of all or a portion of the Shares by the record holder thereof, the Company
shall have an option to purchase all of the Shares transferred at the greater of
the purchase price paid by Purchaser pursuant to this Agreement or the Fair
Market Value of the Shares on the date of transfer. Upon such a transfer, the
person acquiring the Shares shall promptly notify the Secretary of the Company
of such transfer. The right to purchase such Shares shall be provided to the
Company for a period of 30 days following receipt by the Company of written
notice by the person acquiring the Shares.

           (ii) Price for Involuntary Transfer. With respect to any stock to be
transferred pursuant to Section 3(b)(i), the price per Share shall be a price
set by the Board of Directors of the Company that will reflect the current value
of the stock in terms of present earnings and future prospects of the Company.
The Company shall notify Purchaser or his or her executor of the price so
determined within 30 days after receipt by it of written notice of the transfer
or proposed transfer of Shares. However, if the Purchaser does not agree with
the valuation as determined by the Board of Directors of the Company, the
Purchaser shall be entitled to have the valuation determined by an independent
appraiser to be mutually agreed upon by the Company and the Purchaser and whose
fees shall be borne equally by the Company and the Purchaser.

       (c) Assignment. The right of the Company to purchase any part of the
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations; provided, however, that an
assignee, other than a corporation that is the Parent or a 100% owned Subsidiary
of the Company, must pay the Company, upon assignment of such right, cash equal
to the difference between the original purchase price and Fair Market Value, if
the original purchase price is less than the Fair Market Value of the Shares
subject to the assignment.

       (d) Restrictions Binding on Transferees. All transferees of Shares or any
interest therein will receive and hold such Shares or interest subject to the
provisions of this Agreement. Any sale or transfer of the Company's Shares shall
be void unless the provisions of this Agreement are satisfied.

       (e) Termination of Rights. The Right of First Refusal granted the Company
by Section 3(a) above and the option to repurchase the Shares in the event of an
involuntary transfer granted the Company by Section 3(b) above shall terminate
upon the first sale of Common Stock of the Company to the general public
pursuant to a registration statement filed with and declared effective by the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Securities Act"). Upon termination of the
      --------------

                                      -3-
<PAGE>

Right of First Refusal described in Section 3(a) above, a new certificate or
certificates representing the Shares not repurchased shall be issued, on
request, without the legend referred to in Section 6(a)(ii) herein and delivered
to Purchaser.

    4.  Investment and Taxation Representations. In connection with the purchase
of the Shares, Purchaser represents to the Company the following:

        (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the securities. Purchaser is
purchasing these securities for investment for his or her own account only and
not with a view to, or for resale in connection with, any "distribution"
thereof within the meaning of the Securities Act.

        (b) Purchaser understands that the securities have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

        (c) Purchaser understands that the Shares are "restricted securities"
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, Purchaser must hold the Shares indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale. Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

        (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

    5.  Restrictive Legends and Stop-Transfer Orders.

        (a) Legends. The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

             (i)  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
                  ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
                  CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF.

<PAGE>

                  NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN
                  EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION
                  OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
                  REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.

             (ii) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED
                  ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE
                  COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH
                  THE SECRETARY OF THE COMPANY.

       (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

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

    6.  No Employment Rights. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a Parent or Subsidiary
of the Company, to terminate Purchaser's employment or consulting relationship,
for any reason, with or without cause.

    7.  Market Stand-off Agreement. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Shares (other than those included
in the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
Company or such managing underwriters and to execute an agreement reflecting the
foregoing as may be requested by the underwriters at the time of the Company's
initial public offering.

provision shall be excluded from this Agreement, (ii) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (iii)
the balance of the Agreement shall be enforceable in accordance with its terms.

                   Participants' Compensation in excess of the integration

             If you maintain or ever maintained another qualified plan (other

                         N/A
             -------------------------------------------------------------------

             bonuses that, at the Contributing Participant's election, may be
             contributed to the Plan or received by the Contributing Participant
             in cash (Choose one)?

<PAGE>
             Option 1: [_]  Yes.
             Option 2: [X]  No.

             Note: Answer "yes" only if Elective Deferrals will be used
             exclusively on cash bonuses rather than payroll deductions. If no
             option is selected, Option 2 will automatically apply.
