entity that is reasonably likely to result in an AvantGo Material Adverse
Effect. To its knowledge, no person has the right to assert any claims against
AvantGo regarding AvantGo's use of or rights to its patents, trademarks, service
marks, trade names, copyrights, trade secrets or other proprietary rights.
AvantGo is not aware that any of its employees is obligated under any contract
(including licenses, covenants or commitments of any nature) or other agreement,
or subject to any judgment, decree or order of any court or administrative
agency, that would interfere with the use of such employee's best efforts to
promote the interest of AvantGo or that would conflict with AvantGo's business
as currently proposed to be conducted. Neither the execution or delivery of this
Agreement, nor the carrying on of AvantGo's business by the employees of
AvantGo, nor the conduct of AvantGo's business as currently proposed, will, to
the best of AvantGo's knowledge, conflict with or result in a breach of the
terms, conditions, or provisions of, or constitute a default under, any
contract, covenant or instrument under which any such employee is now obligated.
AvantGo does not believe it is or will be necessary to use any inventions of any
of its employees (or persons it currently intends to hire) made prior to their
employment by AvantGo.

          3.10. Title to Property and Assets. AvantGo owns and has good and
                ----------------------------
marketable title to its property and assets free and clear of all mortgages,
liens, loans and encumbrances, except such encumbrances and liens which arise in
the ordinary course of business and do not materially impair AvantGo's ownership
or use of such property or assets. With respect to the property and assets it
leases, AvantGo is in compliance with such leases and, to the best of its
knowledge, holds a valid leasehold interest free of any liens, claims or
encumbrances, mortgages or security interests. All facilities, machinery,
equipment, fixtures, vehicles and other properties owned or leased by AvantGo
are in good operating condition and repair and are reasonably fit and usable for
the purposes for which they are currently being used.

          3.11. Employee Benefit Plans. AvantGo does not have any Employee
                ----------------------
Benefit Plan as defined in the Employee Retirement Income Security Act of 1974,
as amended to date.

          3.12.  Tax Returns and Payments. AvantGo and AvantGo Sub have filed
                 ------------------------
all tax returns and reports as required by law. These returns and reports are
true and correct in all material respects. AvantGo and AvantGo Sub have paid all
taxes and other assessments due. There is no pending dispute with any taxing
authority relating to any of such returns and AvantGo and AvantGo Sub have not
received notice of any proposed liability for any tax to be imposed upon the
properties or assets of AvantGo or AvantGo Sub.

          3.13.  Labor Agreements and Actions. Neither AvantGo nor AvantGo Sub
                 ----------------------------
is bound by or subject to (and none of its assets or properties is bound by or
subject to) any written or oral, express or implied, contract, commitment or
arrangement with any labor union, and no labor union has requested or, to the
best of the AvantGo's and AvantGo Sub's knowledge, has sought to represent any
of the employees, representatives or agents of AvantGo or AvantGo Sub. There is
no strike or other labor dispute involving AvantGo or AvantGo Sub pending, or to
the knowledge of AvantGo and AvantGo Sub threatened, which could have an AvantGo
Material Adverse Effect on the assets, properties, financial condition,
operating results, cash flow, or business of AvantGo or AvantGo Sub (as such
businesses are presently conducted and as they are currently proposed to be
conducted), nor is AvantGo or AvantGo Sub aware of any labor organization
activity involving its employees. The employment of each officer and employee of
AvantGo and AvantGo Sub is terminable at the will of AvantGo and AvantGo Sub,
respectively. To their knowledge, AvantGo and AvantGo Sub have complied in all
material respects with all applicable state and federal equal employment
opportunity laws and with other laws related to employment. To the best of the
AvantGo's and AvantGo Sub's knowledge, no employee of AvantGo or AvantGo Sub,
nor any consultant with whom AvantGo or AvantGo Sub has contracted, is in
violation of any term of any employment contract, proprietary information
agreement, or any other agreement relating to the right of such individual to be
employed by, or to contract with, AvantGo or AvantGo Sub because of the nature
of the business to be conducted by the AvantGo or AvantGo Sub; and the continued
employment by AvantGo and AvantGo Sub of its present employees, and the
performance of AvantGo's and AvantGo Sub's contracts with its independent
contractors will not result in any such violation. AvantGo and AvantGo Sub have
not received any notice from any previous or current employee, consultant or
other individual alleging that such violation has occurred. AvantGo and AvantGo
Sub are not aware that any officer or employee critical to the future success of
AvantGo and AvantGo Sub, or that any group of such employees, intends to
terminate their employment with AvantGo or AvantGo Sub, nor does AvantGo or
AvantGo Sub intend to terminate the employment of any of the foregoing.

subsidiaries in excess of, $50,000, (ii) the license of any patent, copyright,
trade secret or other

                                       12
<PAGE>

proprietary right to or from AvantGo or any of its Subsidiaries, or (iii) the

indebtedness for money borrowed or incurred any other liabilities individually
in excess of $50,000 or in excess of $150,000 in the aggregate, (iii) made any

                 (d)  For the purposes of subsections (b) and (c) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same person or entity (including persons
or entities AvantGo has reason to believe are affiliated therewith) shall be
aggregated for the purpose of meeting the individual minimum dollar amounts of
such subsections.

                 (e)  To its knowledge, AvantGo has performed all material
obligations required to be performed by it as of the date hereof under any
material agreement to which AvantGo is a party or to which it is bound. AvantGo
is not a party to and is not bound by any contract, agreement or instrument, or
subject to any restriction under its Certificate of Incorporation, as amended to
date, or Bylaws, that adversely affects its business as now conducted or
currently proposed to be conducted, its properties or its financial condition.
To AvantGo's knowledge, each such agreement is in full force and effect, except
(a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance, and other laws of general application affecting
enforcement of creditors' rights generally, as limited by laws relating to the
availability of specific performance, injunctive relief, or other equitable
remedies, or (b) to the extent the indemnification provisions contained in the
Investors' Rights Agreement may be limited by applicable federal or state
securities laws, except where such unenforceability would not have a Material
Adverse Effect.

          3.15.  Disclosure. AvantGo has fully provided the Company and the
                 ----------
Stockholders, or their counsel, with all the information which they have
requested for deciding whether to enter into the transactions contemplated
hereby and all information which AvantGo believes is reasonably necessary to
enable the Company and the Stockholders to make such a decision (collectively,
the "Business Materials"). No representation or warranty of AvantGo contained
     ------------------
in this Agreement and the exhibits attached hereto (when read together) contains
any untrue statement of a material fact or omits to state a material fact
necessary in order to make the statements contained herein or therein not
misleading in light of the circumstances under which they were made. To the best
of AvantGo's knowledge, after reasonable investigation, there are no facts which
(individually or in the aggregate) materially adversely affect AvantGo that have
not been set forth in this Agreement, the exhibits hereto, the Ancillary
Documents or in other documents delivered to the Company, the Stockholders or
their attorneys in connection herewith or therewith.

          3.16.  No Conflict of Interest. AvantGo is not indebted, directly or
                 -----------------------
indirectly, to any of its officers or directors or to their respective spouses
or children, in any amount whatsoever other than in connection with expenses or
advances of expenses incurred in the ordinary course of

                                       13
<PAGE>

business. None of AvantGo's officers or directors, or any members of their
immediate families, are, directly or indirectly, indebted to AvantGo (other than
in connection with purchases of AvantGo's stock) or have any direct or indirect
ownership interest in any firm or corporation with which AvantGo is affiliated
or with which AvantGo has a business relationship, or any firm or corporation
which competes with AvantGo except that officers, directors and/or stockholders
of AvantGo may own stock in (but not exceeding two percent of the outstanding
capital stock of) any publicly traded companies that may compete with AvantGo.
To the best of AvantGo's knowledge, none of AvantGo's officers or directors or
any members of their immediate families are, directly or indirectly, interested
in or party to any material contract with AvantGo. AvantGo is not a guarantor or
indemnitor of any indebtedness of any other person, firm or corporation.

          3.17.  Rights of Registration and Voting. Except as contemplated in
                 ---------------------------------
the Investors' Rights Agreement, AvantGo has not granted or agreed to grant any
registration rights, including piggyback rights, to any person or entity. To the
best of AvantGo's knowledge, except as contemplated in the Voting Agreement and
in this Agreement, no stockholders of AvantGo have entered into any agreements
with respect to the voting of capital shares of AvantGo.

          3.18.  Manufacturing and Marketing Rights. AvantGo has not granted
                 ----------------------------------
rights to manufacture, produce, assemble, license, market, or sell its products
to any other person and is not bound by any agreement that affects AvantGo's
exclusive right to develop, manufacture, assemble, distribute, market or sell
its products.

          3.19.  Financial Statements. AvantGo has delivered to the Company or
                 --------------------
its counsel its unaudited financial statements (balance sheet and statements of
operations, and statement of cash flows) as of December 31, 1999 and for the
fiscal year ended December 31, 1999 (the "Financial Statements"). The Financial
Statements have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods indicated and
with each other, except that the Financial Statements may not contain all
footnotes required by generally accepted accounting principles. The Financial
Statements fairly present the financial condition, operating results and cash
flows of AvantGo as of the dates, and for the periods, indicated therein,
subject to normal year-end audit adjustments. Except as set forth in the
Financial Statements, AvantGo has no material liabilities, contingent or
otherwise, other than (i) liabilities incurred in the ordinary course of
business subsequent to December 31, 1999 and (ii) obligations under contracts
and commitments incurred in the ordinary course of business and not required
under generally accepted accounting principles to be reflected in the Financial
Statements, which, in both cases, individually or in the aggregate, are not
material to the financial condition, operating results or cash flows of AvantGo.
Except as disclosed in the Financial Statements, AvantGo is not a guarantor or
indemnitor of any indebtedness of any other person, firm or corporation. AvantGo
maintains and will continue to maintain a standard system of accounting
established and administered in accordance with generally accepted accounting
principles.

AvantGo;

                 (m)  to the best of AvantGo's knowledge, any other event or
condition of any character that might materially and adversely affect the

improvements on the Leased Premises or for the Leased Premises to be used for
its intended purpose. The Company is not in default under any agreement relating

condition, would become a default of a provision under any such agreement,
lease, sublease or other instrument by the Company, or, to the knowledge of the
Company and the Stockholders, the other contracting party except as would not,
individually or in the aggregate, have a Company Material Adverse Effect. The
Company has not released or waived any right under any such agreement, lease,
sublease or other instrument material to the Company other than in the ordinary
course of business consistent with past practices.

               (c)  Neither the Company, nor any of the Stockholders are parties

officers, directors or affiliates, with respect to or affecting the Company's
operations, business, products, assets, properties, sales practices or financial
condition, or related to the consummation of the transactions contemplated
hereby or by the AvantGo Ancillary Documents or the Ancillary Documents. There
are no facts or circumstances known to the Company or any Stockholders which,
assuming such facts or circumstances were known by a potential claimant or
governmental authority on or prior to the Closing Date, would reasonably give
rise to a claim or proceeding that could reasonably result, either individually
or in the aggregate, in a Company Material Adverse Effect, or any change in the
current equity ownership of the Company. The foregoing includes, without

or performed which are in force as of the date hereof. There are no material
claims pending or, to the knowledge of the Company, threatened against the
Company with respect to the quality of or absence of defects in such products or
services nor are there any facts known to the Company relating to the quality of
or absence of defects in such products or services which, assuming such facts
were known by a potential claimant or governmental authority on or prior to the
Closing Date, would reasonably give rise to a material claim or proceeding
having a Company Material Adverse Effect. The Disclosure Statement sets forth a
summary, which is accurate in all material respects, of all returns of products
and all credits and allowances for returned products given to customers during
the period from October 1, 1999 through April 30, 2000 to the extent that such

in the aggregate, and said summary contains a description of any reoccurring

unitary group; (ii) the term "Returns" means all returns, declarations, reports,
                              -------

                 (b)  All Returns required to have been filed by the Company
have been timely filed (taking into account duly granted extensions) and were

beneficiary of any extension of time within which to file any Return, and no
claim has ever been made by any governmental authority in a jurisdiction where
the Company does not file Returns that the Company is or may be subject to
taxation by that jurisdiction, which claim has not been resolved as of the date
hereof.

                 (c)  All Taxes of the Company which have become due (without
regard to any extension of the time for payment and whether or not shown on any
Return) have been paid. The Company has withheld and paid over all Taxes
required to have been withheld and paid over by it and has complied with all
information reporting and back-up withholding requirements relating to Taxes.

included in the Company Financial Statements. The terms of each Employee Benefit
Plan permit the Company to amend or terminate such Employee Benefit Plan at any
time and for any reason without penalty or material liability or expense. None

or from any governmental entity or agency relating to such Employee Benefit Plan

administered, operated and funded in all material respects in accordance with
its terms and in compliance with all applicable requirements of all applicable
laws, statutes, orders, rules and regulations, including, without limitation,
ERISA, COBRA, HIPAA and the Code; (ii) the Company, each fiduciary of such

information and returns relating to such Employee Benefit Plan required to be
filed with any governmental entity or agency have been accurately completed and
timely and properly filed; (v) all notices, statements, reports, descriptions
and other disclosures required to be given or made to participants in such
Employee Benefit Plan or their beneficiaries have been accurately completed and
timely and properly disclosed or provided; (v) neither the Company nor any
fiduciary of such Employee Benefit Plan has engaged in any transaction or acted
or failed to act in a manner that violates the fiduciary requirements of ERISA
or any other applicable law; (vii) no transaction or event has occurred or is
threatened or about to occur (including, without limitation, any of the
transactions contemplated in or by this Agreement) that constitutes or could
constitute a "prohibited transaction," as defined in Section 4975 of the Code or
Section 406 or 407 of ERISA for which a valid exemption is not available; and
(viii) the Company has not incurred, and there exists no condition or set of
circumstances in connection with which the Company, AvantGo or AvantGo Sub could
incur, directly or indirectly, any liability or expense (except for routine
contributions and benefit payments) under ERISA, the Code or any other
applicable law, statute, order, rule or regulation or pursuant to any
indemnification or similar agreement with respect to such Employee Benefit Plan.

               (d)  Each Employee Benefit Plan that is intended to be qualified
under Section 401(a) of the Code is, and at all times since inception has been,
so qualified and its related trust is, and at all times since inception has
been, exempt from taxation under Section 501(a) of the Code. Each such Employee
Benefit Plan either is the subject of an unrevoked favorable determination,
opinion, notification or advisory letter from the IRS with respect to such
Employee Benefit Plan's qualified status under the Code, or has remaining a

pronouncements in which to apply to the IRS for such a letter and to make any
amendments necessary to obtain such a letter from the IRS. Nothing has occurred
since the most recent favorable determination letter issued with respect to each
such Employee Benefit Plan (or, if no such letter has been issued with respect
to such Employee Benefit Plan, since the inception of such Employee Benefit
Plan), and no circumstances exist or are reasonably expected by the Company or
any of the Stockholders to occur, that could adversely affect the qualification
or exemption of such Employee Benefit Plan or its related trust. No such
Employee Benefit Plan is "top-heavy plan," as defined in Section 416 of the
Code.

               (e)  All contributions, premiums and other payments (including,
without limitation, administrative costs, such as trustee and service provider
fees) due or required to be paid to, or with respect to, each Employee Benefit
Plan have been timely paid.

contribute to), any multiemployer plan as defined in Section 3(37) or Section
4001(a)(3) of ERISA or 414(f) of the Code, any multiple employer plan within the
meaning of Section 4063 or 4064 of ERISA or Section 413(c) of the Code, or any
employee benefit plan, fund, program, contract or arrangement that is (or ever
was) subject to Section 412 of the Code, Section 302 of ERISA or Title IV of
ERISA.

(iv) any other group of Persons treated as a single employer under Section
414(o) of the Code.

               (h)  Neither the Company nor any Employee Benefit Plan provides
or has any obligation to provide (or contribute toward the cost of) post-

limitation, death and medical benefits, with respect to any current or former
officer, employee, agent, director or independent contractor of the Company,
other than (i) continuation coverage mandated by Sections 601 through 608 of

Employee Benefit Plan that is qualified under Section 401(a) of the Code.

and each of the Stockholders, threatened with respect to (or against the assets
of) any Employee Benefit Plan, nor, to the knowledge of the Company and each of
the Stockholders, is there a basis for any such action, suit or claim. No
Employee Benefit Plan is currently under investigation, audit or review,
directly or indirectly, by the IRS, the DOL or any other governmental entity or
agency, and, to the knowledge of the Company or any of the Stockholders, no such
action is contemplated or under consideration by the IRS, the DOL or any other
governmental entity or agency.

               (j)  The Company has not made any payments, is not obligated to
make any payments and is not a party (or subject) to any agreement that could
obligate it to make any payments that would not be deductible under Section
162(a)(1), 162(m) or 404 of the Code or by reason of Section 280G of the Code
(or any similar provision of state, local or foreign law).

               (k)  Neither the execution and delivery of this Agreement nor the

the Company, AvantGo or AvantGo Sub or any Employee Benefit Plan, (ii) increase
the amount of compensation due to any individual, (iii) result in any benefit or

in their individual capacities, for the purpose of affecting their action or the

of Incorporation or By-laws of the Company or any insurance policy maintained by
the Company.

               4.31.  No Undisclosed Liabilities. There are no liabilities or

Subsidiaries, if any, to pay any finder's fee, brokerage or agent's commissions
or other like payments in connection with negotiations leading to this Agreement
or the consummation of the transactions contemplated hereby.

                                  ARTICLE V.

                            POST-CLOSING COVENANTS

          5.1.   Tax Matters. The following provisions shall govern the
                 -----------
allocation of responsibility as between the Stockholders, the Company and
AvantGo for certain Tax matters following the Closing Date:

                 (a)  Tax Periods Ending on or Before the Closing Date. The
                      ------------------------------------------------
Stockholders shall, at their own expense, accurately prepare or cause to be
prepared and timely file or cause to be filed all Returns (and pay all Taxes
shown thereon or with respect thereto) with respect to the Company (i) required
to be filed on or before the Closing Date; (ii) pertaining to Taxes of or with
respect to the Company for which its Tax period ends on or before the Closing
Date; and (iii) pertaining to Taxes with respect to which the applicable Tax
period ends on or about the Closing Date or by reason of the Closing with
respect to any material Returns that are filed after the Closing Date. The
Stockholders shall submit such Returns to AvantGo for AvantGo's review and
approval (not to be unreasonably withheld or delayed) no later than thirty (30)
days prior to the due date thereof. Such Returns shall be prepared in a manner
consistent with past practice, except as otherwise required by law. AvantGo
shall prepare or cause to be prepared all other Returns of or with respect to
the Company; provided, however, that if AvantGo prepares Returns for a Taxable
             --------  -------
period that includes (but does not end on) the Closing Date, AvantGo shall
submit drafts of such Returns to the Stockholders for review and shall give the
Stockholders a copy of such final Returns.

                 (b)  Control of Tax Audits and Examinations. The Stockholders
                      --------------------------------------
shall not initiate any claim for refund or file any amended Return with respect
to any tax period ending on or before the Closing Date without the prior written
consent of AvantGo, which consent shall not be unreasonably withheld or delayed.
The Stockholders shall be entitled, at their own expense, to control any audit
or examination by any Taxing authority and contest, resolve and defend against
any assessment, notice of deficiency or other adjustment or proposed adjustment
relating or with respect

                                       37
<PAGE>

to any Taxes of the Company for all Tax periods ending on or before the Closing
Date in which the Company was an "S corporation" within the meaning of Code
Section 1361(a); provided, however, that AvantGo shall have the right to
participate in any such audit, examination or contest at its own expense; and
provided, further, that the Stockholders shall not compromise, settle or resolve
such audit, examination or contest without AvantGo's prior written consent,
which shall not be unreasonably withheld. AvantGo shall have the responsibility
for and shall be entitled, at its own expense (subject to Section 6.3 hereof),
to control any audit or examination by any Taxing authority, initiate any claim
for refund, file any amended Return, and contest, resolve and defend against any
assessment, notice of deficiency or other adjustment relating or with respect to
any Taxes of the Company for all Tax periods beginning on or after the Closing
Date.

                 (c)  Cooperation. Following the Closing Date, each party hereto
                      -----------
agrees to furnish or cause to be furnished to the others, upon request, as
promptly as practicable, such information and assistance as is reasonably
necessary for the filing of all Returns of or with respect to any of the parties
hereto and its subsidiaries, the making of any election related to Taxes of or
with respect to any of the parties hereto or any of its subsidiaries, the
preparation for any audit by any taxing authority, and the prosecution or
defense of any claim, suit or proceeding relating to any Return of or with
respect to any of the parties hereto or any subsidiary thereof.

                 (d)  Apportionment. For purposes of this Agreement, in the case
                      -------------
of any Taxes that are imposed on a periodic basis and are payable for a Taxable
period that includes (but does not end on) the Closing Date, the portion of such
Tax which relates to the portion of such Taxable period ending on the Closing
Date shall (x) in the case of any Taxes other than Taxes based upon or related
to income or receipts, be deemed to be the amount of such Tax for the entire
Taxable period multiplied by a fraction the numerator of which is the number of
days in the Taxable period ending on the Closing Date and the denominator of
which is the number of days in the entire Taxable period, and (y) in the case of
any Tax based upon or related to income or receipts be deemed equal to the
amount which would be payable if the relevant Taxable period ended on the
Closing Date. Any credits relating to a Taxable period that begins before and
ends after the Closing Date shall be apportioned and taken into account
consistent with the applicable Tax, as allocated in the preceding sentence. All
determinations necessary to give effect to the foregoing allocations shall be
made in a manner consistent with prior practice of the Company.

          5.2.   Records Retention. AvantGo agrees to retain possession of all
                 -----------------
accounting, business, financial and tax records and information relating to the
Company in existence on the Closing Date or coming into existence after the
Closing Date which relate to the Company before the Closing Date, until the
sixth anniversary of the Closing Date. For a period of four years following the
six year period specified above, if AvantGo wishes to destroy such records,
AvantGo shall first provide the Stockholders the opportunity to take possession
of same. In addition, from and after the Closing Date, AvantGo agrees to afford
to the Stockholder and their attorneys, accountants and other representatives,
without charge, access upon reasonable notice and during normal business hours,
to such books, records, documents and any and all other information relating to
the Company existing prior to the date hereof as the Stockholders may reasonably
request for any legitimate business purpose.

Agreement, dated as of March 8, 2000 (the "Voting Agreement"), for so long as
                                           ----------------
the Voting Agreement is effective. For purposes of the foregoing, the
Stockholders shall be deemed "Investors" under the terms of the Voting Agreement
and shall have all rights and obligations of other investors thereunder.

          5.4. Employee Matters.
               ----------------

               (a)  By operation of law, all of the Company's employees (each an
"Employee") shall become employees of the Surviving Corporation at the Closing.
 --------
Nothing in this Agreement shall constitute a guarantee that any Employee shall
be entitled to remain in the Surviving Corporation's employ for a specified
period of time.

               (b)  The Employees of the Surviving Corporation shall receive
benefits substantially similar to those offered to AvantGo's similarly situated
employees.

               (c)  The Surviving Corporation shall credit the Employees with
service accrued with the Company prior to the Closing for purposes of
determining eligibility and, if applicable, vesting under the Surviving
Corporation's benefit plans in which the Employees may become eligible to
participate.

years from the Effective Time; provided, however, that the representations and
warranties set forth in Section 4.13 of this Agreement shall survive until the

pursuant to Section 6.3 hereof until the total of all Damages under Section 6.3
exceeds $200,000, in the aggregate (the "Basket Amount"), and after such Damages
exceed the Basket Amount, the Stockholders shall only be obligated to indemnify
the AvantGo Indemnitee for all Damages that exceed the Basket Amount; provided,
however, that the Stockholders shall not be obligated to indemnify the AvantGo
Indemnitees under Section 6.3 for any Damages in excess of $15,700,000, in the

          6.6. Adjustment for Insurance. The amount which an Indemnifying Party
               ------------------------
is required to pay to, for or on behalf of any Indemnified Party pursuant to
this Article VI shall be adjusted (including, without limitation, retroactively)
by any insurance proceeds actually recovered by or on behalf of such Indemnified
Party in reduction of the related indemnifiable loss (the "Indemnifiable Loss").
                                                           ------------------
Amounts required to be paid, as so reduced, are hereinafter sometimes called an
"Indemnity Payment." If an Indemnified Party shall have received or shall have
 -----------------
had paid on its behalf an Indemnity Payment in respect of an Indemnifiable Loss
and shall subsequently receive insurance proceeds in respect of such
Indemnifiable Loss, then the Indemnified Party shall pay to the Indemnifying
Party the amount of such insurance proceeds or, if lesser, the amount of the
Indemnity Payment.

          6.7. Cooperation. Subject to the provisions of Section 6.9, the
               -----------
Indemnifying Party shall have the right, at its own expense, to participate in
the defense of any Third Party Claim.

          6.8. Subrogation. The Indemnifying Party shall not be entitled to
               -----------
require that any action be brought against any other person before action is
brought against it hereunder by the Indemnified Party and shall not be
subrogated to any right of action until it has paid in full or successfully
defended against the Third Party Claim for which indemnification is sought.

          6.9. Indemnification Claims Procedures.
               ---------------------------------

               (a)  Promptly following the receipt of notice by the AvantGo
Indemnitees of a Third Party Claim which the AvantGo Indemnitees believe may
result in a demand for indemnification pursuant to Section 6.3 hereof, AvantGo
shall notify the Stockholders of such claim. Promptly following the receipt of
notice by the Stockholder Indemnitees of a Third Party Claim which the
Stockholder Indemnitees believe may result in a demand for indemnification
pursuant to

                                       41
<PAGE>

Section 6.4 hereof, the Stockholders shall notify AvantGo of such claim. The
party receiving the notice of the Third Party Claim shall notify the other party
hereto of such Third Party Claim. The failure to give such notice shall not
relieve the Indemnifying Party of its obligations under this Agreement except to
the extent that the Indemnifying Party is substantially prejudiced as a result
of the failure to give such notice. Within thirty (30) days after receipt of the
notice by the Indemnifying Party pursuant to the preceding sentence, the
Indemnifying Party shall notify the Indemnified Party whether it elects to
control the defense of the Third Party Claim. If the Indemnifying Party elects
to undertake the defense of such Third Party Claim, it shall do so at its own
expense with counsel of its own choosing and it shall acknowledge in writing its
obligation to indemnify the Indemnified Party with respect to such Third Party
Claim as otherwise set forth in accordance with the provisions of this Article
VI. If the Indemnifying Party elects not to defend the Third Party Claim or
fails to pursue such Third Party Claim reasonably diligently, the Indemnified
Party shall have the right to undertake, conduct and control the defense of such
Third Party Claim through counsel of its own choosing. The party that litigates
or contests the Third Party Claim shall keep the other party fully advised of
the progress and disposition of such claim and the other party shall cooperate
fully with the litigating party and its counsel in the defense of any such
claim.

               (b)  In the event the Indemnifying Party elects not to undertake
the defense of the Third Party Claim or fails to reasonably diligently pursue
the defense of such a claim and the Indemnified Party litigates or otherwise
contests or settles the Third Party Claim, then, provided that a final
determination has been made that the Indemnified Party is entitled to
indemnification hereunder, the Indemnifying Party shall promptly reimburse the
Indemnified Party for all amounts paid to settle such claim or all amounts paid
in satisfaction of a judgment against the Indemnified Party in contesting such
claim and in providing its right to indemnification hereunder, all in accordance
with the provisions of this Article VI. Notwithstanding the foregoing, no
settlement of any Third Party Claim shall be made by the Indemnified Party
without the prior written consent of the Indemnifying Party, which consent shall
not be unreasonably withheld or delayed.

               (c)  No Third Party Claim will be settled by the Indemnifying
Party without the prior written consent of the Indemnified Party, which consent
will not be unreasonably withheld; provided, however, that if such claim asserts
that the Indemnifying Party is jointly and severally liable and the Indemnified
Party shall be fully released from all liability relating to such Third Party
Claim in connection with such settlement, the Indemnifying Party shall not be
required to obtain the consent of the Indemnified Party. If, however, the
Indemnified Party refuses to consent to a bona fide offered settlement which the
Indemnifying Party wishes to accept, the Indemnified Party may continue to
pursue such Third Party Claim free of any participation by the Indemnifying
Party, at the sole expense of the Indemnified Party. In such event, the
Indemnifying Party shall pay to the Indemnified Party the amount of the offer of
settlement which the Indemnified Party refused to accept, plus the costs and
expenses incurred by the Indemnified Party prior to the date the Indemnifying
Party notifies the Indemnified Party of the offer of settlement, all in

inquiry of any kind, on any action taken by the Stockholders' Representative as

dissenter rights under applicable law).

                GLOBALWARE COMPUTING, INC. DISCLOSURE STATEMENT


     The following are exceptions to the representations and warranties of
Globalware Computing, Inc. (the "Company") and the stockholders of the Company
(the "Stockholders") contained in the Agreement and Plan of Merger (the
"Agreement") by and among AvantGo, Inc., GC Acquisition, Inc., the Company and
the Stockholders, dated as of May 26, 2000, and should be considered an integral
part of the Agreement. The section numbers in this Disclosure Statement
correspond to the section numbers in the Agreement; however, any information
disclosed herein under any section number of the Agreement provided by the
Company and the Stockholders shall be deemed disclosed and incorporated into any
other section of the Agreement where it is obvious from the disclosure contained
herein that such disclosure would be appropriate. Any terms defined in the
Agreement shall have the same meaning when used in this Disclosure Statement as
when used in the Agreement, unless the context otherwise requires.

     Inclusion of information in this Disclosure Statement shall not be
construed as an admission that such information is material to the Company or
the assets, business, financial position or results of operations of the
Company.

4.3 Subsidiaries.

     The Company owns the following amounts of stock in the following publicly
     traded companies:

                        Number of Shares
     Name of Company    owned by the Company
     ---------------    --------------------

     Cisco Systems              250
     Puma Technology            400
     Aether Systems             100
     Extended Systems           200

4.4  Ownership Interests.

     See 4.3 for a list of shares of stock in publicly traded companies owned by
     the Company.

4.7  No Violation.

     Under the term's of the Lease Agreement (the "Current Lease Agreement")
     between the Company and Murdoch, Coll & Lillbridge, Inc. (n/k/a Spectrum
     Properties) (the "Landlord"), dated January 27, 1999, relating to the lease
     of the Company's office space at 820 N. Orleans, Suite 210, Chicago, IL
     60610, if the Company gives the Landlord written notice of the Merger, then
     the Landlord will have the right to terminate the Current Lease Agreement
     within 60 days after receipt of the Company's notice of the Merger. If the
     Company does not give the Landlord notice of the Merger, the Landlord may,
     after the Merger, terminate the Current Lease Agreement by giving the
     Company written notice that it is terminating the Current Lease Agreement
     at least 60 days prior to the date of termination set by the Landlord in
     the Landlord's termination notice. The Company has not notified the
     Landlord of the Merger.


     The Company has signed a Lease Agreement (the "New Lease Agreement"), dated
     March 24, 2000, with 420 North Wabash L.L.C. (the "Landlord") acting
     through its managing agent, Friedman Properties, Ltd., with respect to a
     proposed new lease of office space at 420 North Wabash, Chicago, Illinois
     60610. To the Company's knowledge, the New Lease Agreement has not yet been
     signed by the Landlord. The
<PAGE>

     Company had requested an executed counterpart to the New Lease Agreement
     from the Landlord, but the Landlord never delivered to the Company an
     executed counterpart to the New Lease Agreement. The Landlord sent a
     proposed addendum (the "Proposed Addendum") to the New Lease Agreement to
     the Company which indicated, among other things, that the Landlord will be
     unable to deliver the new office space to the Company on June 1, 2000, the
     commencement date under the New Lease Agreement, and requested, among other
     things, certain waivers regarding delivery dates and rent abatements. The
     Landlord also requested that the Company deliver to the Landlord the Letter
     of Credit required to be delivered to the Landlord under the New Lease
     Agreement, but the Company has not delivered such Letter of Credit to the
     Landlord. The Proposed Addendum has not been executed by the Landlord or
     the Company. If the New Lease Agreement is or has been executed by the
     Landlord, the Merger would constitute a default under the New Lease
     Agreement, unless the Company obtains the Landlord's prior written consent
     (which is not to be unreasonably withheld or delayed). The Company has not
     obtained the Landlord's prior consent to the Merger. The Company has given
     the Landlord a $13,770 security deposit in connection with the New Lease
     Agreement.

     Copies of the Current Lease Agreement, the New Lease Agreement and the
     Proposed Addendum have been delivered to AvantGo or its counsel.

4.8  Compliance With Laws - General.

     The Company obtained a Workmen's Compensation Insurance Policy from State
     Farm Insurance on May 23, 2000. Prior to such date, the Company did not
     have any workmen's compensation insurance in place for its employees.

4.9  Financial Information.

     The Company Financial Statements have been provided to AvantGo.

     The Company has a checking account and an investment/sweep account with
     American National Bank, an Account Analysis Checking account and a One

4.13 Intellectual Property; Company Software.

     (d)  The Company received a letter from PUMATECH dated February 22, 2000
          alleging that the Company misrepresented the capabilities of
          PUMATECH's software products in a comparison chart used by the
          Company, and that the chart misused PUMATECH's Intellisync trademark.
          The Company has provided a copy of such letter to AvantGo or its
          counsel. The Company has properly noted PUMATECH's trademark on
          subsequent publishings. In preparing the information included in the
          old Comparison Sheet relating to PUMATECH's software, the Company
          diligently tested PUMATECH's then most current version of the
          software, and also reviewed information available in PUMATECH's
          documentation and on PUMATECH's website with respect to such software.
          The Company then compiled the results of its testing and product
          research with respect to such software and accurately summarized the
          capabilities of PUMATECH's software in relation to the categories of
          capabilities identified in the old Comparison Sheet. Upon receipt of
          the above mentioned letter from PUMATECH, the Company again reviewed
          the capabilities of the then most current available version of
          PUMATECH's software (version 2.6) using the above described methods
          and compared such capabilities to those ascribed to such software in
          the Company's updated version of the Comparison Sheet, which
          accurately reflects the capabilities of the most recent version of
          PUMATECH's software in relation to the specific capabilities
          identified in the updated Comparison Sheet. The Company has not
          received any further correspondence from PUMATECH with respect to the
          foregoing.

     Agreement"), dated March 24, 2000, with 420 North Wabash
     L.L.C. (the "Landlord") acting through its managing agent,
     Friedman Properties, Ltd., with respect to a proposed new
     lease of office space at 420 North Wabash, Chicago, Illinois
     60610. To the Company's knowledge, the New Lease Agreement
     has not yet been signed by the Landlord. The Company had
     requested an executed counterpart to the New Lease Agreement
     from the Landlord, but the Landlord never delivered to the
     Company an executed counterpart to the New Lease Agreement.
     The Landlord sent a proposed addendum (the "Proposed
     Addendum") to the New Lease Agreement to the Company which
     indicated, among other things, that the Landlord will be
     unable to deliver the new office space to

     the Company on June 1, 2000, the commencement date under the
     New Lease Agreement, and requested, among other things,
     certain waivers regarding delivery dates and rent
     abatements. The Landlord also requested that the Company
     deliver to the Landlord the Letter of Credit required to be
     delivered to the Landlord under the New Lease Agreement, but
     the Company has not delivered such Letter of Credit to the
     Landlord. The Proposed Addendum has not been executed by the
     Landlord or the Company. If the New Lease Agreement is or
     has been executed by the Landlord, the Merger would
     constitute a default under the New Lease Agreement, unless
     the Company obtains the Landlord's prior written consent
     (which is not to be unreasonably withheld or delayed). The
     Company has not obtained the Landlord's prior consent to the

4.31 No Undisclosed Liabilities.

     The Company has signed a Lease Agreement (the "New Lease
     Agreement"), dated March 24, 2000, with 420 North Wabash
     L.L.C. (the "Landlord") acting through its managing agent,
     Friedman Properties, Ltd., with respect to a proposed new
     lease of office space at 420 North Wabash, Chicago, Illinois
     60610. To the Company's knowledge, the New Lease Agreement
     has not yet been signed by the Landlord. The Company had
     requested an executed counterpart to the New Lease Agreement
     from the Landlord, but the Landlord never delivered to the
     Company an executed counterpart to the New Lease Agreement.
     The Landlord sent a proposed addendum (the

                                       13
<PAGE>

     "Proposed Addendum") to the New Lease Agreement to the
     Company which indicated, among other things, that the
     Landlord will be unable to deliver the new office space to
     the Company on June 1, 2000, the commencement date under the
     New Lease Agreement, and requested, among other things,
     certain waivers regarding delivery dates and rent
     abatements. The Landlord also requested that the Company
     deliver to the Landlord the Letter of Credit required to be
     delivered to the Landlord under the New Lease Agreement, but
     the Company has not delivered such Letter of Credit to the
     Landlord. The Proposed Addendum has not been executed by the
     Landlord or the Company. If the New Lease Agreement is or
     has been executed by the Landlord, the Merger would
     constitute a default under the New Lease Agreement, unless
     the Company obtains the Landlord's prior written consent
     (which is not to be unreasonably withheld or delayed). The
     Company has not obtained the Landlord's prior consent to the
     Merger. The Company has given the Landlord a $13,770
     security deposit in connection with the New Lease Agreement.

     The Company did not have workmen's compensation insurance coverage until
     May 23, 2000.

     Please note: For issuances of stock and options occurring prior to

reflected below reflect post-split figures.

3.1       Existence, Good Standing, Corporate Authority

AvantGo is in the process of filing the proper applications with the Secretary
of the Commonwealth of Massachusetts and Ohio, respectively, and is currently
not qualified to do business in the Commonwealth of Massachusetts or the State
of Ohio.


3.6       Capitalization

          A table summarizing AvantGo's fully-diluted capitalization has been
          provided to the Company.

          3.6(a)

          Disclosure in Section 3.6(b) is hereby incorporated by reference in
          its entirety.

          3.6(b)

          On February 1, 2000, AvantGo executed a Warrant (the "First Yahoo
          Warrant") entitling Yahoo!, Inc., a Delaware corporation ("Yahoo") to
          purchase 117,558 shares of AvantGo's Preferred Stock.  Upon issuance,
          the designation and price of the First Yahoo Warrant were both subject
          to certain factors.  Upon the closing of AvantGo's Series D Preferred
          Stock financing, the First Yahoo Warrant became exercisable for
          117,558 shares of AvantGo's Series D Preferred Stock, at a price per
          share of $8.36.  The First Yahoo Warrant is subject to vesting and
          shall vest as follows: (1) 58,779 shares thereunder are currently
          vested and exercisable; and (2) 58,779 shares vest on the earlier of
          (a) February 1, 2001; (b) the date on which AvantGo initially sells
          its Common Stock in an underwritten public offering
<PAGE>

          pursuant to a registration statement filed under the Securities Act of
          1933, as amended (the "Act") other than a registration statement on
          Form S-4, S-8 or any successor thereto (the "IPO"); and (c) the date
          on which AvantGo signs a definitive agreement for a change of control
          transaction. Pursuant to the terms of the First Yahoo Warrant, Yahoo
          is entitled to the rights set forth in the Investors' Rights'
          Agreement with respect to the shares subject to the First Yahoo
          Warrant.

          On February 1, 2000, AvantGo executed a Warrant (the "Second Yahoo
          Warrant") entitling Yahoo to purchase 117,558 shares of AvantGo's
          capital stock.  The Second Yahoo Warrant will vest and become
          exercisable only if AvantGo fails to enter into, prior to February 1,
          2001 (the "Trigger Date"), a definitive agreement with Yahoo pursuant
          to which AvantGo agrees to purchase from Yahoo a minimum of $1,000,000
          in advertising over a twelve month period (an "Advertising Deal").
          The Second Yahoo Warrant will be cancelled if AvantGo enters into an
          Advertising Deal with Yahoo prior to the Trigger Date.  If the
          Advertising Deal fails to occur prior to the Trigger Date, then, upon
          the Trigger Date, the Second Yahoo Warrant shall be exercisable for
          shares of (i) the class of Preferred Stock issued in AvantGo's most
          recent financing round with minimum aggregate gross proceeds of
          $500,000 prior to the Trigger Date; or (ii) AvantGo's Common Stock if
          the most recent financing round prior to the Trigger Date is the IPO.
          The exercise price per share shall equal (A) the price per share of
          Preferred Stock paid by the investors in the most recent financing
          round (if the Second Yahoo Warrant is for Preferred Stock); or (B) the
          average daily reported per share closing price (or last sale price, as
          applicable) of the Common Stock on the applicable national securities
          exchange during the period of the most recent twenty (20) business
          days, ending on the last business day (on which the national
          securities exchanges were open for trading) before the Trigger Date
          (if the Second Yahoo Warrant is for Common Stock).  If the Second
          Yahoo Warrant becomes exercisable for shares of AvantGo's Preferred
          Stock, then under the terms of the Second Yahoo Warrant, AvantGo shall
          use all reasonable efforts to promptly obtain for Yahoo the rights
          existing under the Investors' Rights Agreement, as amended, with
          respect to the shares subject to the Second Yahoo Warrant.

          AvantGo executed a Warrant (the "Imagine Warrant") entitling Imagine
          Health, Inc. ("Imagine") to purchase 358,851 shares of Series D
          Preferred Stock at a price per share equal to $8.36.

          On March 8, 2000, AvantGo and Imagine executed a Letter Agreement
          pursuant to which Imagine is entitled to purchase $3,000,000 of Common
          Stock in a private financing to occur contemporaneous with an IPO and
          at the price per share applicable to the Common Stock at the IPO, on
          such terms and conditions as Imagine and AvantGo mutually agree,
          provided that (A) the terms and conditions of such purchase of Common
          Stock are memorialized prior to AvantGo's initial filing of its
          registration statement under the Act; (B) Imagine's right to purchase
          Common Stock shall be conditioned only upon the occurrence of the IPO;
          and (C)

                                      -2-
<PAGE>

          the shares so purchased shall be "Registrable Securities" as defined
          in the Investors' Rights Agreement.

          On March 8, 2000, AvantGo executed a Letter Agreement pursuant to
          which affiliates of Goldman Sachs ("GS") are entitled to purchase
          $3,000,000 of Common Stock in a private financing to occur
          contemporaneous with an IPO and at the price per share applicable to
          the Common Stock at the IPO, on such terms and conditions as GS and
          AvantGo mutually agree, provided that (A) the terms and conditions of
          such purchase of Common Stock are memorialized prior to AvantGo's
          initial filing of its registration statement under the Act; and (B)
          GS's right to purchase Common Stock shall be conditioned only upon the
          occurrence of the IPO; and (C) the shares so purchased shall be
          "Registrable Securities" as defined in the Investors' Rights
          Agreement.

          On March 7, 2000, AvantGo and the Ford Motor Company ("Ford") executed
          a Letter Agreement pursuant to which Ford is entitled to purchase
          $5,000,000 of Common Stock in a private financing to occur
          contemporaneous with an IPO and at the price per share applicable to
          the Common Stock at the IPO, on such terms and conditions as Ford and
          AvantGo mutually agree, provided that (A) the terms and conditions of
          such purchase of Common Stock are memorialized prior to AvantGo's
          initial filing of its registration statement under the Act; (B) Ford's
          right to purchase Common Stock shall be conditioned only upon the
          occurrence of the IPO; and (C) the shares so purchased shall be
          "Registrable Securities" as defined in the Investors' Rights
          Agreement.

          AvantGo has a commitment to issue 5,000 shares of AvantGo's Series D
          Preferred Stock to Chapura, Inc. ("Chapura"), a licensor of
          intellectual property, upon Chapura's entering into a Reseller
          Agreement with AvantGo on terms reasonably acceptable to AvantGo.

          AvantGo's Board of Directors has approved a Seventh Amended and
          Restated Certificate of Incorporation (the "Seventh Certificate"), the
          effectiveness of which is subject to the IPO and stockholder approval,
          which authorizes the issuance of two classes of stock, Preferred Stock
          and Common Stock, each with a par value of $0.0001.  The Seventh
          Certificate authorizes One Hundred Sixty Million (160,000,000) shares,
          of which Ten Million (10,000,000) shares are authorized Preferred and
          One Hundred Fifty Million (150,000,000) shares are authorized Common.
          The Seventh Certificate has not yet been approved by AvantGo's
          stockholders.

          On May 19, 2000, AvantGo's Board of Directors approved the 2000 Stock

          The 2000 Plan will be administered by a Plan Administrator (currently
          the compensation committee of AvantGo's Board of Directors). Unless
          terminated earlier, the 2000 Plan will terminate ten years after the
          date of adoption by the Board of Directors. The 2000 Plan has not yet
          been approved by AvantGo's stockholders.

          On May 19, 2000, AvantGo's Board of Directors adopted the 2000
          Employee Stock Purchase Plan (the "ESPP"), the effectiveness of which
          is subject to the IPO and stockholder approval. The Board of Directors
          has reserved for the ESPP 350,000 shares of AvantGo common stock plus
          an automatic annual increase equal to the lesser of (i) 700,000
          shares, (ii) 1% of the outstanding common shares at the end of the
          immediately preceding fiscal year on a fully diluted basis, or (iii) a
          lesser amount determined by the Board of Directors. Unless terminated
          earlier, the ESPP will have a term of 10 years.

          On May 19, 2000, AvantGo's Board of Directors approved the Stock
          Option Grant Program for Nonemployee Directors (the "Nonemployee
          Directors Plan"), the effectiveness of which is subject to the IPO.
          The Nonemployee Directors Plan provides for awards of stock options to
          nonemployee directors of AvantGo under the 2000 Plan.  Under the
          Nonemployee Directors Plan, eligible directors would receive an
          initial nonqualified stock option grant of 50,000 shares of AvantGo's
          Common Stock (the "Initial Grant").  Thereafter, each eligible
          director will receive an additional annual nonqualified stock option
          grant of 7,500 shares of AvantGo's Common Stock (the "Annual Grant").
          Initial Grants vest and become exercisable over four years at the rate
          of 1/48th per month following the director's initial appointment or
          election.  Annual Grants vest and become exercisable immediately upon
          grant.

<PAGE>

payment or incurrence of such Damages; (ii) a description of any evidence

AvantGo and the Escrow Agent specifying in reasonable detail the basis for the
dispute (a "Dispute Notice").
            --------------

     (c)  If (i) the Stockholders' Representative approves all or a part of the

Dispute Notice has not been delivered to the Escrow Agent, the Escrow Agent
shall release to AvantGo that number of Escrow Shares equal to a quotient, (x)
the numerator of which shall equal the Claim Amount (or such part thereof which
is approved by the Stockholders' Representative and not disputed) and (y) the
denominator of which shall equal the Common Price Per Share (as defined in
Section 2.2(f)). The Escrow Agent shall give written notice to AvantGo and the

Agent of a Dispute Notice, then AvantGo and the Stockholders' Representative
shall jointly submit their dispute to J.A.M.S. Endispute (the "Arbitrator") in

AvantGo and the Stockholders' Representative) for resolution. If the Arbitrator
is unwilling to act as arbitrator for such dispute, a substitute arbitrator (the
"Substitute") shall be selected as follows: AvantGo shall select an appointing
 ----------
arbitrator and the Stockholders' Representative shall select an appointing
arbitrator, and the two appointing arbitrators so selected shall mutually
appoint the Substitute who shall be a nationally recognized arbitration
association not acting for AvantGo or any of the Stockholders; provided,
                                                               --------
however, that if either party fails to select an appointing arbitrator within
-------
thirty (30) days after the expiration of the second thirty (30) day period
referred to in this Section 2.2(d), the appointing arbitrator selected by the
other party shall serve as the Substitute if such arbitrator is a nationally

Substitute. The Arbitrator's or Substitute's determination, as the case may be,
as to a dispute shall be final and binding on the parties hereto. AvantGo shall
pay the fees and expenses of the Arbitrator.

the factual basis giving rise to such Claim, the Common Price Per Share shall
equal $8.36; and (ii) with respect to any Claim, if it is conceded or unalleged
in the Claim Notice by AvantGo, or if it is determined by the Arbitrator or the
Substitute (after taking into account all relevant facts and circumstances),

knowledge of the factual basis giving rise to such Claim, the Common Price Per
Share shall be determined as follows: (A) if the AvantGo Stock is traded on a

                                --------  -------
the Interim Rolling Average and the Secondary Rolling Average exceeds 20% of the
Interim Rolling Average, then the Common Price Per Share shall equal the average
of the Interim Rolling Average and the Secondary Rolling Average; or (B) if the
AvantGo Stock is not then traded on a national securities exchange or quoted in
a national inter-dealer quotation system, the Common Price Per Share shall be an

Escrow Agent shall thereafter be discharged from all liability hereunder.

Escrow Agent may conclusively rely, without any obligation of investigation or
inquiry of any kind, on any action taken by the Stockholders' Representative as
having been fully authorized and approved by all necessary action by each
Stockholder.

terms of the Merger Agreement shall prevail.

     A.   Pursuant to the provisions of the Merger Agreement, the parties
thereto intend to effect the merger of AvantGo Sub with and into the Company
(the "Merger").
      -------

     B.   Under the terms of the Merger Agreement, the execution and delivery of
this Rep. Letter is a condition precedent to the obligations of the parties

     NOW, THEREFORE, the undersigned Stockholder hereby represents, warrants,
covenants and attests to AvantGo and AvantGo Sub as follows:

                            A  T  T  E  S  T  E  D

1.   REPRESENTATIONS OF THE STOCKHOLDER

     (a)  The undersigned Stockholder hereby represents and warrants to AvantGo
as follows:

          (i)  That such Stockholder, either in such Stockholder's individual
capacity or by virtue of a relationship with a "Purchaser Representative" (as
that term is defined in Rule 501(h) of Regulation D promulgated under the
Securities Act of 1933, as amended (the "Securities Act")), has such financial
                                         --------------
and business knowledge as necessary to evaluate the merits and risks of
acquiring shares of AvantGo Series E Preferred Stock (the "Series E") pursuant
                                                           --------
to the Merger Agreement, and to protect such Stockholder's interests therein;

          (ii) Such Stockholder has read and understands the Merger Agreement
attached hereto as Exhibit A (including the AvantGo Ancillary Documents and the
                   ---------
Ancillary Documents appended thereto), has had an opportunity to discuss
AvantGo's business, management, financial affairs and the terms and conditions
of the offering of the Series E with AvantGo's management and has had an
opportunity to review AvantGo's facilities, and understands that such
<PAGE>

discussions and any other written information delivered by AvantGo to such
Stockholder were intended to describe the aspects of AvantGo's business which it
believes to be material; and

                    (iii)  Such Stockholder understands that the Series E have
not been, and will not be, registered under the Securities Act, by reason of a
specific exemption from the registration provisions of the Securities Act which
depends upon, among other things, the bona fide nature of the investment intent
and the accuracy of the Stockholders' representations as expressed herein, and
that the Series E are therefore "restricted securities" under applicable U.S.
federal and state securities laws. Such Stockholder also understands that as a
result of this classification, such Stockholder must hold the Series E
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. Such Stockholder
acknowledges that AvantGo has no obligation to register or qualify the Series E
for resale except as set forth in AvantGo's Investors' Rights Agreement, as
amended, and 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 Series E,
and on requirements relating to AvantGo which are outside of such Stockholder's
control, and which AvantGo is under no obligation and may not be able to
satisfy.

          (b)  The undersigned Stockholder hereby confirms that the Series E to
be acquired by such Stockholder will be acquired for investment for such
Stockholder's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and that such Stockholder has no
present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Rep. Letter, such Stockholder further
represents that such Stockholder does not presently have any contract,
undertaking, agreement or arrangement with any person to sell, transfer or grant
participations to such person or to any third person, with respect to any of the
Series E. Such Stockholder has not been formed for the specific purpose of
acquiring the Series E.

          (c)  The undersigned Stockholder either (i) is an "Accredited
Investor" as defined in Rule 501(a) of Regulation D promulgated under the
Securities Act (a copy of which is attached hereto as Exhibit B), or (ii) has
                                                      ---------
had the assistance of a Purchaser Representative in evaluating the relative
risks and merits of acquiring and holding the Series E. If such Stockholder is
not an Accredited Investor, then such Stockholder represents and warrants as
follows:

                    (i)    Such Stockholder's Purchaser Representative has
training, knowledge or experience in financial, business or tax matters which
qualify such Purchaser Representative to act in the capacity of Purchaser
Representative for the undersigned Stockholder and so as to be capable, alone or
together with the undersigned Stockholder, of evaluating the relative merits and
risks of acquiring and holding the Series E and to allow the undersigned
Stockholder to protect such Stockholder's own interests therein; and

                    (ii)   Such Stockholder's Purchaser Representative is not an
"affiliate" (as that term is defined in the Securities Act), director, officer
or other employee of AvantGo or AvantGo Sub or a beneficial owner of 10% or more
of the equity interest in either AvantGo or
<PAGE>

AvantGo Sub, and there is no material relationship between such Purchaser
Representative or such Purchaser Representative's affiliates, and AvantGo or
AvantGo Sub or their respective affiliates which now exists or is mutually
understood to be contemplated, or which has existed at any time during the
previous two years, including, without limitation, the payment of any fees,
commissions, or similar form of remuneration.

          (d)  Such Stockholder holds of record and beneficially owns the number
of shares of Company Capital Stock set forth opposite such Stockholder's name on
Exhibit A attached to the Merger Agreement (the "Stockholder's Shares"), free
---------                                        --------------------
and clear of any restrictions on transfer.

          (e)  None of the Stockholder's Shares are subject to any mortgage,
pledge, lien, encumbrance, charge, hypothecation, or any other security

          (a)  "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 DISTRIBUTION 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;" and

          (b)  Any legend required by the Blue Sky laws of any state to the

     3. Market Standoff
        ---------------

        The undersigned Stockholder hereby agrees that, during the period of
duration specified by AvantGo and an underwriter of Common Stock or other
securities of AvantGo, following the effective date of the first registration
statement of AvantGo filed under the Securities
<PAGE>

Act to effect an initial public offering (up to, but not exceeding, one hundred
eighty (180) days), it shall not, to the extent requested by AvantGo and such
underwriter, directly or indirectly sell, offer to sell, contract to sell
(including, without limitation, any short sale), grant any option to purchase or
otherwise transfer or dispose of any Series E (or Common Stock issuable upon
conversion of the Series E) held by it at any time during such period except
Common Stock included in such registration (the "Market Standoff"); provided,
                                                 ---------------    --------
however, that the directors and officers of AvantGo agree to a provision
-------
substantially similar to the Market Standoff. In order to enforce the foregoing
covenant, AvantGo may impose stop-transfer instructions with respect to the
Series E (or Common Stock issuable upon conversion of the Series E, as the case
may be) (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period, and the Stockholder agrees
that, if so requested, such Stockholder will execute an agreement in the form
provided by the underwriter containing terms which are essentially consistent
with the provisions of this Section 3. Notwithstanding the foregoing, the
obligations described in this Section 3 shall not apply to a registration
relating solely to employee benefit plans on Form S-1 or Form S-8 or similar
forms which may be promulgated in the future, or a registration relating solely
to an SEC Rule 145 transaction on Form S-4 or similar forms which may be
promulgated in the future.

Company's termination of your employment for Cause (as defined below) or your
termination of employment without Good Reason (as defined below), of which
________ of the Restricted Shares are Escrow Shares and _______ of which were
issued to you in connection with the Merger.

          (a) Transfer Restrictions.  You shall not transfer, assign, encumber
              ---------------------
or otherwise dispose of any Restricted Shares, and any such transfer shall be
null and void and of no force and effect.  You understand that the certificates
evidencing the Restricted Shares shall bear the following legend with respect to
the Right of Repurchase, in addition to other appropriate legends:

     "THE SHARES REPRESENTED HEREBY MAY NOT BE SOLD, ASSIGNED, TRANSFERRED,
     ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN COMPLIANCE WITH THE
     TERMS OF A WRITTEN EMPLOYMENT AGREEMENT BETWEEN THE COMPANY AND THE
     REGISTERED HOLDER OF THE SHARES (OR THE PREDECESSOR IN INTEREST TO THE
     SHARES). SUCH AGREEMENT GRANTS TO THE COMPANY CERTAIN REPURCHASE RIGHTS
     UPON TERMINATION OF EMPLOYMENT WITH THE COMPANY. THE SECRETARY OF THE
     COMPANY WILL UPON WRITTEN REQUEST FURNISH A COPY OF SUCH AGREEMENT TO THE
     HOLDER HEREOF WITHOUT CHARGE."

          (b) Lapse of Repurchase Right. The Right of Repurchase shall lapse
              -------------------------
with respect to 62.5% of the Restricted Shares upon your completion of 15 full
months of continuous employment following the date hereof. The Right of
Repurchase shall lapse with respect to an additional 4.167% of the Restricted
Shares upon your completion of each full month of continuous employment
thereafter, such that 100% of the Restricted Shares shall be released from the
Right of Repurchase after your completion of 24 full months of continuous
employment.  Notwithstanding anything to the contrary herein, in the event that
either the Company terminates your employment without Cause or you terminate
your employment for Good Reason, the Right of Repurchase shall lapse in its
entirety.

          (c) Repurchase Cost. If AvantGo exercises the Right of Repurchase, it
              ---------------
shall pay you an amount in cash or cash equivalents equal to $8.36 for each of
the Restricted Shares being repurchased.

          (d) Exercise of Right of Repurchase. The Right of Repurchase shall be
              -------------------------------
exercisable only by written notice delivered to you prior to the expiration of
the 30-day period
<PAGE>

next following the date of termination of your employment. The notice shall set
forth the date on which the repurchase is to be effected. Such date shall not be
more than 30 days after the date of the notice. The certificate(s) representing
the Restricted Shares to be repurchased shall, prior to the close of business on
the date specified for the repurchase, be delivered to AvantGo properly endorsed
for transfer. AvantGo shall, concurrently with the receipt of such
certificate(s), pay to you the purchase price determined according to subsection
(c) above. Payment shall be made in cash or cash equivalents. The Right of
Repurchase shall terminate with respect to any Restricted Shares for which it
has not been timely exercised pursuant to this subsection (d).

          (e) Additional Shares or Substituted Securities. In the event of the
              -------------------------------------------
declaration of a stock dividend, the declaration of an extraordinary dividend
payable in a form other than stock, a spin-off, a stock split, an adjustment in
conversion ratio, a recapitalization or a similar transaction affecting
AvantGo's outstanding securities without receipt of consideration, any new,
substituted or additional securities or other property (including money paid
other than as an ordinary cash dividend) that by reason of such transaction are
distributed with respect to any Restricted Shares or into which such Restricted
Shares thereby become convertible shall immediately be subject to the Right of
Repurchase. Appropriate adjustments to reflect the distribution of such
securities or property shall be made to the number and/or class of the
Restricted Shares. After each such transaction, appropriate adjustments shall
also be made to the price per share to be paid upon the exercise of the Right of
Repurchase in order to reflect any change in AvantGo's outstanding securities
effected without receipt of consideration therefor; provided, however, that the
aggregate purchase price payable for all of the Restricted Shares shall remain
the same.

          (f) Termination of Rights as Stockholder. If AvantGo makes available,
              ------------------------------------
at the time and place and in the amount and form provided in this Letter
Agreement, the consideration for the Restricted Shares to be repurchased in
accordance herewith, then after such time you shall no longer have any rights as
a holder of such Restricted Shares (other than the right to receive payment of
such consideration in accordance with subsection (d)). Such Restricted Shares
shall be deemed to have been repurchased in accordance with the applicable
provisions hereof, whether or not the certificate(s) therefor have been
delivered as required by this Letter Agreement.

          (g) Escrow. Upon issuance, the certificates for Restricted Shares
              ------
shall be deposited in escrow with AvantGo to be held in accordance with the
provisions hereof. Any new, substituted or additional securities or other
property described in subsection (e) above shall immediately be delivered to
AvantGo to be held in escrow, but only to the extent the Shares are at the time
Restricted Shares. All regular cash dividends on Restricted Shares (or other
securities at the time held in escrow) shall be paid directly to you and shall

                         CONFIDENTIAL INFORMATION AND
                        INVENTION ASSIGNMENT AGREEMENT


     As a condition of my becoming employed (or my employment being continued)
by or retained as a consultant (or my consulting relationship being continued)
AvantGo, Inc., a Delaware corporation, with any of its current or future
subsidiaries, affiliates, successors or assigns (collectively, the "Company"),
                                                                    -------
and in consideration of my employment or consulting relationship with the
Company and my receipt of the compensation now and hereafter paid to me by the
Company, I agree to the following:

     1.   Employment or Consulting Relationship. I understand and acknowledge
          -------------------------------------
that this Agreement does not alter, amend or expand upon any rights I may have
to continue in the employ of, or in a consulting relationship with, or the
duration of my employment or consulting relationship with, the Company under any
existing agreements between the Company and me or under applicable law.  Any
employment or consulting relationship between the Company and me, whether
commenced prior to or upon the date of this Agreement, shall be referred to
herein as the "Relationship."
               ------------

     2.   Period of Employment. I understand that the period of my employment
          --------------------
shall be governed by Section 9 of the Letter Agreement between me and Globalware
Computing, Inc. as of even date herewith.

     3.   Confidential Information.
          ------------------------

          (a) Company Information. I agree at all times during the term of my
              -------------------
Relationship with the Company and thereafter, to hold in strictest confidence,
and not to use, except for the benefit of the Company, or to disclose to any
person, firm, corporation or other entity without written authorization of the
Board of Directors of the Company, any Confidential Information of the Company
which I obtain or create. I further agree not to make copies of such
Confidential Information except as authorized by the Company. I understand that
"Confidential Information" means any Company proprietary information, technical
 ------------------------
data, trade secrets or know-how, including, but not limited to, research,
product plans, products, services, suppliers, customer lists and customers
(including, but not limited to, customers of the Company on whom I called or
with whom I became acquainted during the Relationship), prices and costs,
markets, software, developments, inventions, laboratory notebooks, processes,
formulas, technology, designs, drawings, engineering, hardware configuration
information, marketing, licenses, finances, budgets or other business
information disclosed to me by the Company either directly or indirectly in
writing, orally or by drawings or observation of parts or equipment or created
by me during the period of the Relationship, whether or not during working
hours. I understand that "Confidential Information" includes, but is not limited
                          ------------------------
to, information pertaining to any aspects of the Company's business which is
either information not known by actual or potential competitors of the Company
or is proprietary information of the Company or its customers or suppliers,
whether of a technical nature or otherwise.  I further understand that
Confidential Information does not include any of the foregoing items which has
become publicly and widely
<PAGE>

known and made generally available through no wrongful act of mine or of others
who were under confidentiality obligations as to the item or items involved.

          (b)  Former Employer Information. I represent that my performance of
               ---------------------------
all terms of this Agreement as an employee or consultant of the Company have not
breached and will not breach any agreement to keep in confidence proprietary
information, knowledge or data acquired by me in confidence or trust prior or
subsequent to the commencement of my Relationship with the Company, and I will
not disclose to the Company, or induce the Company to use, any inventions,
confidential or proprietary information or material belonging to any previous
employer or any other party.

          (c)  Third Party Information. I recognize that the Company has
               -----------------------
received and in the future will receive from third parties their confidential or
proprietary information subject to a duty on the Company's part to maintain the
confidentiality of such information and to use it only for certain limited
purposes. I agree to hold all such confidential or proprietary information in
the strictest confidence and not to disclose it to any person, firm or
corporation or to use it except as necessary in carrying out my work for the
Company consistent with the Company's agreement with such third party.

     4.  Inventions.
         ----------

          (a)  Inventions Retained and Licensed.  I have attached hereto, as
               --------------------------------
Exhibit A, a list describing with particularity all inventions, original works
---------
of authorship, developments, improvements, and trade secrets which were made by
me prior to the commencement of the Relationship (collectively referred to as

"Prior Inventions"), which belong solely to me or belong to me jointly with
 ----------------
another, which relate in any way to any of the Company's proposed businesses,
products or research and development, and which are not assigned to the Company
hereunder; or, if no such list is attached, I represent that there are no such
Prior Inventions.  If, in the course of my Relationship with the Company, I
incorporate into a Company product, process or machine a Prior Invention owned
by me or in which I have an interest, the Company is hereby granted and shall
have a non-exclusive, royalty-free, irrevocable, perpetual, worldwide license
(with the right to sublicense) to make, have made, copy, modify, make derivative
works of, use, sell and otherwise distribute such Prior Invention as part of or
in connection with such product, process or machine.

          (b)  Assignment of Inventions. I agree that I will promptly make full
               ------------------------
written disclosure to the Company, will hold in trust for the sole right and
benefit of the Company, and hereby assign to the Company, or its designee, all
my right, title and interest throughout the world in and to any and all
inventions, original works of authorship, developments, concepts, know-how,
improvements or trade secrets, whether or not patentable or registrable under
copyright or similar laws, which I may solely or jointly conceive or develop or
reduce to practice, or cause to be conceived or developed or reduced to
practice, during the period of time in which I am employed by or a consultant of
the Company (collectively referred to as "Inventions"), except as provided in
                                          ----------
Section 4(e) below.  I further acknowledge that all inventions, original works
of authorship, developments, concepts, know-how, improvements or trade secrets
which are made by me (solely or jointly with others) within the scope of and
during the period of my Relationship with the Company are "works made for hire"
                                                           -------------------
(to the greatest
<PAGE>

extent permitted by applicable law) and are compensated by my salary (if I am an
employee) or by such amounts paid to me under any applicable consulting
agreement or consulting arrangements (if I am a consultant), unless regulated
otherwise by the mandatory law of the state of California.

          (c) Maintenance of Records. I agree to keep and maintain adequate and
              ----------------------
current written records of all Inventions made by me (solely or jointly with
others) during the term of my Relationship with the Company. The records may be
in the form of notes, sketches, drawings, flow charts, electronic data or
recordings, laboratory notebooks, and any other format. The records will be
available to and remain the sole property of the Company at all times. I agree
not to remove such records from the Company's place of business except as
expressly permitted by Company policy which may, from time to time, be revised
at the sole election of the Company for the purpose of furthering the Company's
business.

          (d) Patent and Copyright Rights. I agree to assist the Company, or
              ---------------------------
its designee, at the Company's expense, in every proper way to secure the
Company's rights in the Inventions and any copyrights, patents, trademarks, mask
work rights, moral rights, or other intellectual property rights relating
thereto in any and all countries, including the disclosure to the Company of all
pertinent information and data with respect thereto, the execution of all
applications, specifications, oaths, assignments, recordations, and all other
instruments which the Company shall deem necessary in order to apply for,
obtain, maintain and transfer such rights and in order to assign and convey to
the Company, its successors, assigns and nominees the sole and exclusive rights,
title and interest in and to such Inventions, and any copyrights, patents, mask
work rights or other intellectual property rights relating thereto. I further
agree that my obligation to execute or cause to be executed, when it is in my
power to do so, any such instrument or papers shall continue after the
termination of this Agreement until the expiration of the last such intellectual
property right to expire in any country of the world. If the Company is unable
because of my mental or physical incapacity or unavailability or for any other
reason to secure my signature to apply for or to pursue any application for any
United States or foreign patents or copyright registrations covering Inventions
or original works of authorship assigned to the Company as above, then I hereby
irrevocably designate and appoint the Company and its duly authorized officers
and agents as my agent and attorney in fact, to act for and in my behalf and
stead to execute and file any such applications and to do all other lawfully
permitted acts to further the application for, prosecution, issuance,
maintenance or transfer of letters patent or copyright registrations thereon
with the same legal force and effect as if originally executed by me. I hereby
waive and irrevocably quitclaim to the Company any and all claims, of any nature
whatsoever, which I now or hereafter have for infringement of any and all
proprietary rights assigned to the Company.

     5.  Returning Company Documents. I agree that, at the time of termination
         ---------------------------
of my Relationship with the Company, I will deliver to the Company (and will not
keep in my possession, recreate or deliver to anyone else) any and all devices,
records, data, notes, reports, proposals, lists, correspondence, specifications,
drawings, blueprints, sketches, laboratory notebooks, materials, flow charts,
equipment, other documents or property, or reproductions of any aforementioned
items developed by me pursuant to the Relationship or otherwise belonging to the
Company, its successors or assigns.  I further agree that to any property
situated on the Company's premises and owned by the Company, including disks and
other storage media, filing
<PAGE>

cabinets or other work areas, is subject to inspection by Company personnel at
any time with or without notice. In the event of the termination of the
Relationship, I agree to sign and deliver the "Termination Certification"
                                               -------------------------
attached hereto as Exhibit B.

     6.   Notification to Other Parties.
          -----------------------------

          (a) Employees. In the event that I leave the employ of the Company, I
              ---------
hereby consent to notification by the Company to my new employer about my rights
and obligations under this Agreement.

          (b) Consultants. I hereby grant consent to notification by the
              -----------
Company to any other parties besides the Company with whom I maintain a

four (24) months immediately following the termination of my Relationship with
the Company for any reason, whether with or without cause, I shall not either

Company, or take away such employees or consultants, or attempt to solicit,
induce, recruit, encourage or take away employees or consultants of the Company,
either for myself or for any other person or entity.  Further, for a period of
twenty-four (24) months following termination of my Relationship with the
Company for any reason, with or without cause, I shall not solicit any licensor
to or customer of the Company or licensee of the Company's products, in each
case, that are known to me, with respect to any business, products or services
that are competitive to the products or services offered by the Company or under
development as of the date of termination of my Relationship with the Company.

     8.   Representations and Covenants.
          -----------------------------

          (a) Facilitation of Agreement. I agree to execute promptly any proper

Ladies and Gentlemen:

     We have acted as counsel for AvantGo, Inc., a Delaware corporation
("AvantGo"), and GC Acquisition, Inc., an Illinois corporation and a wholly-
owned subsidiary of AvantGo ("AvantGo Sub"), in connection with the transactions
contemplated by that certain Agreement and Plan of Merger dated as of May 26,
2000 (the "Merger Agreement") by and among AvantGo, AvantGo Sub, you and the
Stockholders (as defined in the Merger Agreement).  This opinion is being
furnished to you pursuant to Section 6.2(d) of the Merger Agreement.  All
capitalized terms used herein and not otherwise defined shall have the
respective meanings assigned to them in the Merger Agreement.

     For purposes of rendering the opinion expressed herein, we have reviewed
the Merger Agreement (including the Exhibits and Schedules attached thereto).

     In addition, we have examined such corporate records, documents and
instruments of each of AvantGo and AvantGo Sub and certificates of public
officials and have reviewed such questions of law as we have deemed necessary
for the purpose of rendering the opinions set forth herein. As to matters of
fact material to the opinions expressed herein, we have relied upon the
representations and warranties as to factual matters contained in and made by
AvantGo and AvantGo Sub pursuant to the Merger Agreement, a certificate of an
officer of AvantGo (the "AvantGo Officer's Certificate"), a certificate of an
officer of AvantGo Sub (the "AvantGo Sub Officer's Certificate" and together
with AvantGo Officer's Certificate, the "Officer's Certificates") and other
certificates and statements of government officials. We have also examined
originals or copies of such corporate documents or records of AvantGo and
AvantGo Sub as we have considered appropriate for the opinions expressed herein.
We have assumed for the purposes of this opinion that the signatures on
documents and instruments examined by us are authentic, that each document is
what it purports to be, and that all documents submitted to us as copies or
facsimiles conform with the originals, which facts we have not independently
verified. We have not conducted a docket search in any jurisdiction with respect
to litigation that may be pending against AvantGo or AvantGo Sub or any of their
officers or directors or undertaken any further inquiry other than as stated
herein. In making our examination of documents executed by persons or entities
other than AvantGo or AvantGo Sub, we have assumed that each other person or
entity has the power and authority to execute and deliver, and to perform and
observe the provisions of, such documents, and the due authorization by each
such entity of all requisite action and the due execution and delivery of such
documents by each such entity.

     Our opinion in paragraph 1 below is based solely upon our review of
certificates of public officials in the relevant states.

     In connection with the opinion expressed in paragraph 3 below, we have
examined AvantGo's Certificate of Incorporation, as amended, AvantGo's Bylaws,
AvantGo's stock record books and journals in our possession, AvantGo's stock
certificate books and AvantGo's minute books in our possession. AvantGo has
represented to us that these records are complete and accurate and constitute
all of AvantGo's documents with respect to the issuance of shares of its capital
stock, options, warrants or other rights to purchase shares of its capital
stock. We have relied on AvantGo's representation to us that the information
expressed in paragraph 3 below with respect to the outstanding stock, options,
warrants or other rights is true and complete. We have also relied on AvantGo's
representations to us as to the nature of the consideration received for such
shares. Although we have no knowledge that the information as to outstanding
stock, options, warrants and other rights provided by AvantGo and reflected in
paragraph 3 is incorrect, based on the examination referred to above, we are not
in a position to verify its accuracy or completeness, other than to say that our
records are not inconsistent with such information.

     In connection with the opinion expressed in paragraph 4 below, we have
examined the Articles of Incorporation, the Bylaws, the stock record books and
journals of AvantGo Sub in our possession, AvantGo Sub's stock certificate books
and AvantGo Sub's minute books in our possession. AvantGo Sub has represented to
us that these records are complete and accurate and constitute all of AvantGo
Sub's documents with respect to the issuance of shares of its capital stock. We
have also relied on AvantGo Sub's representations to us as to the nature of the
consideration received for such shares. Although we have no knowledge that the
information as to outstanding stock provided by AvantGo Sub and reflected in
paragraph 4 is incorrect, based on the examination referred to above, we are not
in a position to verify its accuracy or completeness, other than to say that our
records are not inconsistent with such information.

     In rendering the opinions set forth in paragraphs 5 and 6 below as to
factual matters, we have relied without independent verification upon the
information contained in a certificate of secretary delivered by the Company.

     Based upon our examination of and reliance upon the foregoing and subject
to the limitations, exceptions, qualifications and assumptions set forth below
and except as set forth in the Merger Agreement and the AvantGo Disclosure
Statement attached thereto, we are of the opinion that as of the date hereof:

     1.   AvantGo is a corporation validly existing and in good standing under
the laws of the State of Delaware and AvantGo Sub is a corporation validly
existing and in good standing under the laws of the State of Illinois. AvantGo
is duly qualified to do business in California.

     2.   Each of AvantGo and AvantGo Sub has the corporate power and authority
to own, lease and operate its respective properties and assets, and to carry on
its business as now being conducted, except where the failure to have such power
and authority would not have an AvantGo Material Adverse Effect.

knowledge without independent investigation, the authorized capitalization of

                 contemporaneous with AvantGo's initial sale of its Common Stock
                 in an underwritten public offering pursuant to a registration
                 statement filed under the Securities Act of 1933, as amended
                 other than a registration on Form S-4, Form S-8 or any
                 successor form (the "IPO") and at the price per share
                 applicable to the Common Stock at the IPO, on terms and
                 conditions as Imagine and AvantGo mutually agree; (vii) the
                 right of Goldman Sachs to purchase $3,000,000 of Common Stock
                 in a private financing to occur contemporaneous with the IPO
                 and at a price per share applicable to the Common Stock at the
                 IPO, on terms and conditions as Goldman Sachs and AvantGo
                 mutually agree; (viii) the right of Ford Motor Company ("Ford")
                 to purchase $5,000,000 of Common Stock in a private financing
                 to occur contemporaneous with the IPO and at a price per share
                 applicable to the Common Stock at the IPO, on the terms and
                 conditions as Ford and AvantGo mutually agree; and (ix)
                 9,213,600 shares of common stock authorized for issuance under
                 the Stock Plan, and (x) outstanding options issued under the
                 Stock Plan, there are, to our knowledge without independent
                 investigation, no outstanding (A) securities convertible into
                 or exchangeable for any capital stock of AvantGo or any of its
                 subsidiaries; (B) options, warrants or other rights to purchase
                 or subscribe to capital stock of AvantGo or any of its
                 subsidiaries or securities convertible or exchangeable for
                 capital stock of AvantGo or any of its subsidiaries; or (C)
                 contracts, commitments, agreements, understandings,
                 arrangement, calls or claims of any kind relating to the
                 issuance of any capital stock of AvantGo or any of its
                 subsidiaries.

     4.   The authorized capital of AvantGo Sub consists of 1,000 shares of
Common Stock, $0.0001 par value per share, 100 of which are issued, outstanding
and owned by AvantGo.

     5.   The execution and delivery of the Merger Agreement and the AvantGo
Ancillary Documents to be signed by each of AvantGo and AvantGo Sub have been
duly authorized by the Board of Directors of each of AvantGo and AvantGo Sub and
the stockholders and shareholders of AvantGo and AvantGo Sub, respectively, to
the extent legally required, and no other proceedings on the part of AvantGo or
AvantGo Sub are necessary to authorize the execution, delivery or performance of
the Merger Agreement or any AvantGo Ancillary Document to be signed by each of
AvantGo and AvantGo Sub. Each of the Merger Agreement and the AvantGo Ancillary
Documents to be signed by AvantGo and AvantGo Sub is a valid and binding
obligation of each of AvantGo and AvantGo Sub, to the extent each is a party
thereto, enforceable against each of AvantGo and AvantGo Sub in accordance with
its terms.

            6.   Neither the execution and delivery of the Merger Agreement or
the AvantGo Ancillary Documents by each of AvantGo and AvantGo Sub, nor the
consummation by AvantGo and AvantGo Sub of the transactions contemplated by the
Merger Agreement and such AvantGo Ancillary Documents in accordance with their
respective terms will (a) conflict with or result in a breach of any provisions
of AvantGo's Certificate of Incorporation, as amended or Bylaws or of AvantGo
Sub's Articles of Incorporation or Bylaws; (b) violate, conflict with, result in
a breach of any provision of, constitute a default (or an event which, with
notice or lapse of time or both, would constitute a default) under, result in
the termination, or in a right of termination or cancellation of, accelerate the
performance, or create a right to accelerate the performance, required by,
result in the triggering of an increase in any payment or other material
obligations pursuant to, result in the creation of any lien, security interest,
charge or encumbrance upon any of the material properties of each of AvantGo or
AvantGo Sub under, or result in being declared void, voidable, or without
further binding effect, any of the terms, conditions or provisions of any
agreement listed on Section 3.14 to the AvantGo Disclosure Statement, except as
would not have an AvantGo Material Adverse Effect; (c) contravene or conflict
with or constitute a violation of any provision of any law, regulation,
judgment, injunction, order or decree known to us to be binding upon or
applicable to AvantGo or AvantGo Sub, except for any of the foregoing matters
which would not have an AvantGo Material Adverse Effect; or (d) to our
knowledge, require any material consent, approval, order or authorization of, or
declaration, qualification, designation, filing or registration with, any
domestic governmental or regulatory authority, the failure to obtain or make
which would have an AvantGo Material Adverse Effect.

            7.   Except as set forth in the AvantGo Disclosure Statement, to our
knowledge, without independent investigation, there is no litigation or
proceeding, in law or in equity, and there are no proceedings or governmental
investigations before any commission or other administrative authority, pending
or threatened against either AvantGo or AvantGo Sub or any of their officers,
directors or affiliates with respect to or affecting each of AvantGo and AvantGo
Sub's operations, business, products, assets, properties, sales practices or
financial condition, or related to the consummation of the transactions
contemplated by the Merger Agreement or by the AvantGo Ancillary Documents or
the Ancillary Documents.

            Our opinions expressed above are specifically subject to the
following limitations, exceptions, qualifications and assumptions:

            A.   As used in this opinion, the expression "we are not aware" or
                 the phrase "to our knowledge" means as to matters of fact that,
                 based on the actual knowledge of individual attorneys within
                 the firm principally responsible for handling current matters
                 for each of AvantGo and AvantGo Sub and after an examination of
                 documents referred to herein and after inquiries of certain
                 officers of each of AvantGo and AvantGo Sub, we find no reason
                 to believe that the opinions
<PAGE>

Globalware Computing, Inc.
May 26, 2000
Page 6

                 expressed are factually incorrect, but beyond that we have made
                 no factual investigation for the purposes of rendering this
                 opinion. Specifically, but without limitation, we have made no
                 inquiries of securities holders or employees (other than
                 obtaining representations from certain officers of each of
                 AvantGo and AvantGo Sub as described above) of AvantGo or
                 AvantGo Sub.

            B.   This opinion relates solely to the General Corporation Law of
                 the State of Delaware and the federal law of the United States,
                 and we express no opinion with respect to the effect or
                 application of any other laws. Accordingly, we express no
                 opinion as to the laws of other jurisdictions and, to the
                 extent that matters covered by this opinion are governed by
                 laws other than the law of the State of Delaware or the federal
                 law of the United States, we have assumed that, where
                 applicable, the laws of the other states are identical in
                 substance to the law of the State of Delaware. Special rulings
                 of authorities administering such laws or opinions of other
                 counsel have not been sought or obtained.

            C.   We express no opinion as to the effect of bankruptcy,
                 insolvency, reorganization, moratorium, fraudulent conveyance
                 and other similar laws affecting enforcement of creditors'
                 rights generally, and by general principles of equity
                 (regardless of whether enforcement is considered in a
                 proceeding at law or in equity).

            D.   The relief of debtors or the rights and remedies of creditors
                 generally, including without limitation the effect of statutory
                 or other law regarding fraudulent conveyances and preferential
                 transfers.

            E.   We express no opinion as to either AvantGo's or AvantGo Sub's
                 compliance or noncompliance with applicable federal or state
                 antifraud or antitrust statutes, laws, rules and regulations or
                 federal or state securities laws.

            F.   Limitations imposed by state law, federal law or general
                 equitable principles upon the specific enforceability of any of
                 the remedies, covenants or other provisions of any applicable
                 agreement and upon the availability of injunctive relief or
                 other equitable remedies, regardless of whether enforcement of
                 any such agreement is considered a proceeding in equity or at
                 law.

            G.   The effect of court decisions, invoking statutes or principles
                 of equity, which have held that certain covenants and
                 provisions of agreements are unenforceable where enforcement of
                 such covenants or provisions under the circumstances would
                 violate the enforcing party's implied covenant of good faith
                 and fair dealing.

            H.   The effect of Section 1670.5 of the California Civil Code or
                 any other California law, federal law or equitable principle
                 which provides that a court may refuse to
<PAGE>

Globalware Computing, Inc.
May 26, 2000
Page 7

                 enforce, or may limit the application of, a contract or any
                 clause thereof which the court finds to have been
                 unconscionable at the time it was made or contrary to public
                 policy.

            I.   The unenforceability under certain circumstances of provisions
                 expressly or by implication waiving broadly or vaguely stated
                 rights, unknown future rights or defenses to obligations or
                 rights granted by law, when such waivers are against public
                 policy or prohibited by law.

            J.   The unenforceability under certain circumstances of provisions
                 to the effect that rights or remedies are not exclusive, that
                 rights or remedies may be exercised without notice, that every
                 right or remedy is cumulative and may be exercised in addition
                 to or with any other right or remedy, that election of a
                 particular remedy or remedies does not preclude recourse to one
                 or more remedies, or that failure to exercise or delay in
                 exercising rights or remedies will not operate as a waiver of
                 any such right or remedy.

            K.   Any provisions of the Merger Agreement requiring that waivers
                 must be in writing may not be binding or enforceable if a non-
                 executory oral agreement has been created modifying any such
                 provision or an implied agreement by trade practice or course
                 of conduct has given rise to a waiver.

            L.   We express no opinion as to the enforceability of provisions in
                 the Merger Agreement that purport to establish evidentiary
                 standards or to make determinations conclusive.

            M.   We express no opinion as to the enforceability of the
                 indemnification provisions of the Merger Agreement to the
                 extent the provisions thereof may be subject to limitations of
                 public policy and the effect of applicable statutes and
                 judicial decisions.
<PAGE>

     This opinion is rendered as of the date first written above solely for your
benefit in connection with the Merger Agreement and may not be delivered to,
quoted or relied upon by any person other than you, or for any other purpose,
without our prior written consent.  Our opinion is expressly limited to the
matters set forth above and we render no opinion, whether by implication or
otherwise, as to any other matters relating to either AvantGo or AvantGo Sub.
We assume no obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinions expressed herein.

                              Very truly yours,

Ladies and Gentlemen:

     We have acted as counsel for Globalware Computing, Inc., an Illinois
corporation ("Globalware"), in connection with the transactions contemplated by
that certain Agreement and Plan of Merger dated as of May 26, 2000 (the "Merger
Agreement") by and among Globalware, AvantGo, Inc., a Delaware corporation, GC
Acquisition, Inc., an Illinois corporation and a wholly owned subsidiary of
AvantGo, Inc., and the Stockholders (as defined in the Merger Agreement). This
opinion is being furnished to you at the request of Globalware pursuant to
Section 1.6(b)(iv) of the Merger Agreement. All capitalized terms used herein
and not otherwise defined shall have the respective meanings assigned to them in
the Merger Agreement.

     For purposes of rendering the opinion expressed herein, we have reviewed
the Merger Agreement (including the Exhibits and Schedules attached thereto) and
the Ancillary Agreements to be signed by Globalware.

     In addition, we have examined such corporate records, documents and
instruments of Globalware and certificates of public officials and have reviewed
such questions of law as we have deemed necessary for the purpose of rendering
the opinions set forth herein. As to matters of fact material to the opinions
expressed herein, we have relied upon the representations and warranties as to
factual matters contained in and made by Globalware and the Stockholders
pursuant to the Merger Agreement, a certificate of Globalware and its officers,
and other certificates and statements of government officials. We have also
examined originals or copies of such corporate documents or records of
Globalware as we have considered appropriate for the opinions expressed herein.
We have assumed for the purposes of this opinion that the signatures on
documents and instruments examined by us are authentic, that each document is
what it purports to be, and that all documents submitted to us as copies or
facsimiles conform with the originals. We have not independently investigated or
verified any of the foregoing. We have not conducted a docket search in any
jurisdiction with respect to litigation that may be pending against Globalware
or any of its officers or directors or undertaken any further inquiry other than
as stated herein. In making
<PAGE>

our examination of documents executed by persons or entities other than
Globalware, we have assumed that each other person or entity has the power and
authority to execute and deliver, and to perform and observe the provisions of,
such documents, and the due authorization by each such entity of all requisite
action and the due execution and delivery of such documents by each such entity.

     Our opinion in paragraph 1 below is based solely upon our review of
certificates of public officials in the State of Illinois, and we have assumed
that such certificates, which were given or dated earlier than the date of this
opinion letter, have remained accurate as far as relevant to the opinions
contained in paragraph 1, from such earlier date through and including the date
of this opinion letter.

     In connection with the opinions expressed in paragraph 3 below, we have
examined Globalware's Articles of Incorporation and Bylaws, each as amended to
date, Globalware's stock record books and journals in our possession,
Globalware's stock certificate books, and Globalware's minute books in our
possession. Globalware has represented to us that these records are true and
complete and constitute all of Globalware's documents with respect to the
issuance of shares of its capital stock, options, warrants or other rights to
purchase shares of its capital stock. We have relied on Globalware's
representation to us that the information expressed in paragraph 3 below with
respect to the outstanding stock, options, warrants or other rights is true and
complete. We have also relied on Globalware's representations to us as to the
nature and amount of the consideration received for such shares. Although we
have no knowledge that the information as to outstanding stock, options,
warrants and other rights provided by Globalware and reflected in paragraph 3 is
not true and complete, based on the examination referred to above, we are not in
a position to verify its truth or completeness, other than to say that our
records are not inconsistent with such information.

     In rendering the opinions set forth in paragraphs 4 and 5 below as to
factual matters, we have relied without independent verification upon the
information contained in a certificate of Globalware.

     Based upon our examination of and reliance upon the foregoing and subject
to the limitations, exceptions, qualifications and assumptions set forth below
and except as set forth in the Merger Agreement and the Disclosure Statement
attached thereto, we are of the opinion that as of the date hereof:

     1.  Globalware is a corporation validly existing and in good standing under
the laws of the State of Illinois.

     2.  Globalware has the corporate power and authority to own, lease and
operate its properties and assets, and to carry on its business as now being
conducted, except where the failure to have such power and authority would not
have a Company Material Adverse Effect.

     3.  Except as set forth in the Disclosure Statement, to our knowledge
without independent investigation or verification, the authorized capitalization
of Globalware immediately prior to the closing (except as otherwise noted) is as
follows:

           a)  The total authorized capital stock of the Company consists of
               10,000 shares of common stock, no par value, 900 shares of which
               are issued and outstanding as of the date of the Merger Agreement
               and 100 of which are held in the treasury of the Company.  There
               are no shares of capital stock of the Company of any other class
               authorized.

           b)  The Company has reserved 100 shares of Common Stock for issuance
               to key managerial employees and key consultants of the Company
               pursuant to the Company Stock Plan.  The Company Stock Plan has
               been duly adopted by the Company's Board of Directors and
               approved by the Company's stockholders.

           c)  Except as set forth in a) and b) above, and except for 84 shares
               of Common Stock issuable upon the exercise of outstanding Company
               Options under the Option Agreements, as set forth in Exhibit A to
               the Merger Agreement, there are, to our knowledge without
               independent investigation or verification, no outstanding (A)
               securities convertible into or exchangeable for any capital stock
               of Globalware; (B) options, warrants or other rights to purchase
               or subscribe to capital stock of Globalware; or (C) contracts,
               commitments, agreements, understandings, arrangement, calls or
               claims of any kind relating to the issuance of any capital stock
               of Globalware.

     4.  The execution and delivery of the Merger Agreement and the Ancillary
Documents to be signed by Globalware have been duly authorized by the Board of
Directors of Globalware and the Stockholders of Globalware, and no other
proceedings on the part of Globalware are necessary to authorize the execution,
delivery or performance of the Merger Agreement or any Ancillary Document to be
signed by Globalware. Each of the Merger Agreement and the Ancillary Documents
to be signed by Globalware is a valid and binding obligation of Globalware,
enforceable against Globalware in accordance with its terms.

     5.  Except as set forth in the Disclosure Statement, neither the execution
and delivery by Globalware of the Merger Agreement or the Ancillary Documents to
be signed by Globalware, nor the consummation by Globalware of the transactions
contemplated by the Merger Agreement and such Ancillary Documents in accordance
with their respective terms will (a) conflict with or result in a breach of any
provisions of Globalware's Articles of Incorporation or Bylaws, each as amended
to date; (b) violate, result in a breach of any provision of, or constitute a
default (or an event which, with notice or lapse of time or both,
<PAGE>

AvantGo, Inc.
May 26, 2000
Page 4

would constitute a default) under, any agreement listed on Section 4.16 to the
Disclosure Statement, except as would not have a Company Material Adverse
Effect; (c) violate any provision of any law, regulation, judgment, injunction,
order or decree known to us to be binding upon or applicable to Globalware,
except for any of the foregoing matters which would not have a Company Material
Adverse Effect; or (d) to our knowledge, other than the Filings, require any
material consent, approval, order or authorization of, or declaration,
qualification, designation, filing or registration with, any domestic
governmental or regulatory authority, the failure to obtain or make which would
have an Company Material Adverse Effect.

     6.  Except as set forth in the Disclosure Statement, to our knowledge,
without independent investigation or verification, there is no litigation or
proceeding, in law or in equity, and there are no proceedings or governmental
investigations before any commission or other administrative authority, pending
or threatened against Globalware or any of its officers, directors or affiliates
with respect to or affecting Globalware's operations, business, products,
assets, properties, sales practices or financial condition, or related to the
consummation of the transactions contemplated by the Merger Agreement or by the
Ancillary Documents to which Globalware is a party.

     Our opinions expressed above are specifically subject to the following
limitations, exceptions, qualifications and assumptions:

     A.   As used in this opinion, the expression "we are not aware" or the
          phrase "to our knowledge" (or any similar concept) means as to matters
          of fact that, based on the actual knowledge of individual attorneys
          within the firm principally responsible for handling current matters
          for Globalware and after an examination of documents referred to
          herein and after inquiries of certain officers of Globalware, we find
          no reason to believe that the opinions expressed are factually
          incorrect, but beyond that we have made no factual investigation for
          the purposes of rendering this opinion.  Specifically, but without
          limitation, we have made no inquiries of securities holders or
          employees (other than obtaining representations from certain officers
          of Globalware as described above) of Globalware.

     B.   This opinion relates solely to the Illinois Business Corporation Act
          of 1983, as amended, and the federal law of the United States, and we
          express no opinion with respect to the effect or application of any
          other laws.  Special rulings of authorities administering such laws or
          opinions of other counsel have not been sought or obtained.

     C.   We express no opinion as to the effect of bankruptcy, insolvency,
          reorganization, moratorium, fraudulent conveyance and other similar
          laws affecting enforcement of creditors' rights generally, and by
          general principles of equity (regardless of whether enforcement is
          considered in a proceeding at law or in equity).

     D.   The relief of debtors or the rights and remedies of creditors
          generally, including without limitation the effect of statutory or
          other law regarding fraudulent conveyances and preferential transfers.

     E.   We express no opinion as to Globalware's compliance or noncompliance
          with applicable federal or state antifraud or antitrust statutes,
          laws, rules and regulations or federal or state securities laws.

     F.   Limitations imposed by state law, federal law or general equitable
          principles upon the specific enforceability of any of the remedies,
          covenants or other provisions of any applicable agreement and upon the
          availability of injunctive relief or other equitable remedies,
          regardless of whether enforcement of any such agreement is considered
          a proceeding in equity or at law.

     G.   The effect of court decisions, invoking statutes or principles of
          equity, which have held that certain covenants and provisions of
          agreements are unenforceable where enforcement of such covenants or
          provisions under the circumstances would violate the enforcing party's
          implied covenant of good faith and fair dealing.

     H.   The effect of any state law, federal law or equitable principle which
          provides that a court may refuse to enforce, or may limit the
          application of, a contract or any clause thereof which the court finds
          to have been unconscionable at the time it was made or contrary to
          public policy.

     I.   The unenforceability under certain circumstances of provisions
          expressly or by implication waiving broadly or vaguely stated rights,
          unknown future rights or defenses to obligations or rights granted by
          law, when such waivers are against public policy or prohibited by law.

     J.   The unenforceability under certain circumstances of provisions to the
          effect that rights or remedies are not exclusive, that rights or
          remedies may be exercised without notice, that every right or remedy
          is cumulative and may be exercised in addition to or with any other
          right or remedy, that election of a particular remedy or remedies does
          not preclude recourse to one or more remedies, or that failure to
          exercise or delay in exercising rights or remedies will not operate as
          a waiver of any such right or remedy.

     K.   Any provisions of the Merger Agreement requiring that amendments or
          waivers must be in writing may not be binding or enforceable if a non-
          executory oral agreement has been created modifying any such provision
          or an implied agreement by trade practice or course of conduct has
          given rise to an amendment or a waiver.

     L.   We express no opinion as to the validity, legality, binding effect or
          enforceability of provisions in the Merger Agreement that purport to
          establish evidentiary standards or to make determinations conclusive.

     M.   We express no opinion as to the validity, legality, binding effect or
          enforceability of the indemnification provisions of the Merger
          Agreement to the extent the provisions thereof may be subject to
          limitations of public policy and the effect of applicable statutes and
          judicial decisions.

     This opinion is rendered as of the date first written above solely for your
benefit in connection with the Merger Agreement and may not be delivered to,
quoted or relied upon by any person other than you, or for any other purpose,
without our prior written consent.  Our opinion is limited to the matters
expressly set forth above and we render no opinion, whether by implication or
otherwise, as to any other matters relating to Globalware.  We assume no
obligation to advise you of facts, circumstances, events or developments which
hereafter may be brought to our attention and which may alter, affect or modify
the opinions expressed herein.

                              Very truly yours,

                 NON-SOLICITATION AND NON-COMPETITION AGREEMENT

     This Non-Solicitation and Non-Competition Agreement (the "Agreement") is
                                                               ---------
delivered, as of May 26, 2000, to AvantGo, Inc., a Delaware corporation

("AvantGo"), by Gilad Ben-Yoseph, Roey Ben-Yoseph, Yoav Ben-Yoseph, Long Barnes
---------
and James Joyce (each a "Stockholder" and together the "Stockholders") pursuant
                         -----------                    ------------
to Section 1.6(b)(v) of that certain Agreement and Plan of Merger by and among
AvantGo, GC Acquisition, Inc., an Illinois corporation and wholly owned
subsidiary of AvantGo ("AvantGo Sub"), Globalware Computing, Inc., an Illinois
                        -----------
corporation (the "Company"), and the Stockholders, dated as of May 26, 2000 (the
                  -------
"Merger Agreement").  All capitalized terms used herein but not otherwise
 ----------------
defined herein shall have the meanings ascribed to them in the Merger Agreement.

                              W I T N E S S E T H

     A.  Pursuant to the provisions of the Merger Agreement, the parties
thereto intend to effect the merger of AvantGo Sub with and into the Company
(the "Merger");
      -------

     B.  Pursuant to Section 1.6(b)(v) of the Merger Agreement, the Stockholders
are required to execute and deliver to AvantGo this Non-Solicitation and Non-
Competition Agreement;

     C.  The execution and delivery of this Agreement is a condition precedent
to the obligations of the parties under the Merger Agreement; and

     D.  The execution and delivery of this Agreement serves as a material
inducement for AvantGo to (i) enter into the Merger Agreement, and (ii) issue
shares of AvantGo Stock in exchange for all of the shares of Company Capital
Stock owned by the undersigned Stockholders;

     NOW, THEREFORE, each undersigned Stockholder hereby agrees as follows:

                               A G R E E M E N T

     1.  Non-Solicitation; Non-Competition.  Each Stockholder agrees that from
         ---------------------------------
and after the date hereof and continuing for a period of one (1) year after the
Closing Date (such period being referred to herein as the "Restricted Period"),
                                                           -----------------
such Stockholder shall not, directly or indirectly, either for itself or for any
other person or entity, without the prior written consent of the Company:

         (a)   anywhere in the United States, (i) engage or participate in, (ii)
     assist, advise or be connected with (including as an employee, owner,
     partner, shareholder, officer, director, advisor, consultant, agent or
     (without limitation by the specific enumeration of the foregoing)
     otherwise), (iii) permit AvantGo's name to be used by or (iv) render
     services for, any business involving the development, manufacture, sale or
<PAGE>

     marketing of software or services that enable the extension of the Internet
     to mobile devices (a "Competing Business");
                           ------------------

         (b)   take any action which might divert from AvantGo or any of its
     subsidiaries any opportunity (each, an "Opportunity") which would be within
                                             -----------
     the scope of AvantGo's or its subsidiaries' then business but shall rather
     offer each Opportunity to AvantGo, which AvantGo may, in its sole
     discretion, decide to pursue or not;

         (c)   solicit, attempt to solicit, aid in the solicitation of or accept
     any orders from any person or entity who is or has been a customer of
     AvantGo or its subsidiaries, at any time during the period beginning one
     year prior to the date hereof through the Restricted Period, to purchase
     products or services from any Competing Business;

         (d)   solicit, attempt to solicit or aid in the solicitation of any
     person or entity who is or has been a customer, supplier, licensor,
     licensee or person or entity having any other business relationship with
     AvantGo or its subsidiaries, at any time during the period beginning one
     year prior to the date hereof through the Restricted Period, to cease doing
     business with or alter its business relationship with AvantGo or its
     subsidiaries; or

         (e)   solicit or hire any person or entity who is a director, officer,
     employee, independent contractor or agent of AvantGo or its subsidiaries to
     perform services for any person or entity other than AvantGo or its
     subsidiaries or to terminate his or her employment with AvantGo or its
     subsidiaries.

     2.  Specific Performance; Judicial Reformation.  Each Stockholder agrees
         ------------------------------------------
that any violation by it of Section 1 of this Agreement would be highly
injurious to AvantGo and would cause irreparable harm to AvantGo.  By reason of
the foregoing, each Stockholder consents and agrees that if it violates any
provision of Section 1 of this Agreement, AvantGo shall be entitled, in addition
to any other rights and remedies that it may have, to apply to any court of
competent jurisdiction for specific performance and/or injunctive or other
relief in order to enforce, or prevent any continuing violation of, the
provisions of such section.  In the event any Stockholder breaches a covenant
contained in this Agreement, the Restricted Period applicable to it with respect
to such breached covenant shall be extended for the period of such breach.  Each
Stockholder also recognizes that the territorial, time and scope limitations set
forth in Section 1 are reasonable and are properly required for the protection
of AvantGo and in the event that any such territorial, time or scope limitation
is deemed to be unreasonable by a court of competent jurisdiction, AvantGo and
the Stockholders agree, and submit, to the reduction of any or all of said
territorial, time or scope limitations to such an area, period or scope as said
court shall deem reasonable under the circumstances.  Each Stockholder
represents, warrants and acknowledges that it has available to it sufficient
other means of support so that observance of the covenants contained in Section
1 shall not deprive it of its ability to earn a livelihood or support such
Stockholder's dependents.

     3.  Amendment and Governing Law.  This Agreement may not be amended or
         ---------------------------
modified except by an express written agreement signed by each of the
Stockholders and a duly

                                      -2-
<PAGE>

authorized officer of AvantGo. The terms of this Agreement and the resolution of
any disputes will be governed by Delaware law.

     4.  Assignment.  This Agreement shall be binding upon and inure to the
         ----------
benefit of the parties hereto and their respective heirs, successors and
permitted assigns.  This Agreement may not be assigned by any of the
Stockholders (whether by operation of law or otherwise) without the prior
written consent of the Company.

     5.  Waiver.  No waiver of any provisions of this Agreement shall be valid
         ------
unless in writing and signed by the waiving party.  No waiver of any of the
provisions of this Agreement shall be deemed, or shall constitute, a waiver of
any other provision, whether or not similar, nor shall any waiver constitute a
continuing waiver, unless so provided in the waiver.

     6.  Unenforceability.  If any provisions of this Agreement (or portions
         ----------------
thereof) shall, for any reason, be invalid or unenforceable, such provisions (or
portions thereof) shall be ineffective only to the extent of such invalidity or
unenforceability, and the remaining provisions of this Agreement (or portions
thereof) shall nevertheless be valid, enforceable and of full force and effect.

     7.  Agreement.  The parties hereto agree that this Agreement supersedes the
         ---------
respective Non-Competition, Non-Solicitation and Non-Disclosure Agreements
entered into by the Company and each of the respective Stockholders prior to the
date hereof.

     7.  Counterparts.  This Agreement may be executed in multiple counterparts,
         ------------
each of which shall be deemed to be an original and all of which taken together
shall constitute a single instrument.

                            [Signature Page Follows]

                         CONFIDENTIAL INFORMATION AND
                        INVENTION ASSIGNMENT AGREEMENT


     As a condition of my becoming employed (or my employment being continued)
by or retained as a consultant (or my consulting relationship being continued)
AvantGo, Inc., a Delaware corporation, with any of its current or future
subsidiaries, affiliates, successors or assigns (collectively, the "Company"),
                                                                    -------
and in consideration of my employment or consulting relationship with the

Company, I agree to the following:

     1.   Employment or Consulting Relationship.  I understand and acknowledge
          -------------------------------------
that this Agreement does not alter, amend or expand upon any rights I may have
to continue in the employ of, or in a consulting relationship with, or the
duration of my employment or consulting relationship with, the Company under any
existing agreements between the Company and me or under applicable law.  Any
employment or consulting relationship between the Company and me, whether
commenced prior to or upon the date of this Agreement, shall be referred to
herein as the "Relationship."

     2.   At-Will Employment.  I understand and acknowledge that my Relationship

-----------------
another, which relate in any way to any of the Company's proposed businesses,
products or research and development, and which are not assigned to the Company

               ------------------------
written disclosure to the Company, will hold in trust for the sole right and
benefit of the Company, and hereby assign to the Company, or its designee, all
my right, title and interest throughout the world in and to any and all
inventions, original works of authorship, developments, concepts, know-how,
improvements or trade secrets, whether or not patentable or registrable under
copyright or similar laws, which I may solely or jointly conceive or develop or
reduce to practice, or cause to be conceived or developed or reduced to

the Company (collectively referred to as "Inventions"), except as provided in
                                          ----------
Section 4(e) below.  I further acknowledge that all inventions, original works

                                                                        -----
made for hire" (to the greatest extent permitted by applicable law) and are

recordings, laboratory notebooks, and any other format.  The records will be
available to and remain the sole property of the Company at all times.  I agree
not to remove such records from the Company's place of business except as
expressly permitted by Company policy which may, from time to time, be revised
at the sole election of the Company for the purpose of furthering the Company's
business.

          (d)  Patent and Copyright Rights.  I agree to assist the Company, or

its designee, at the Company's expense, in every proper way to secure the
Company's rights in the Inventions and any copyrights, patents, trademarks, mask
work rights, moral rights, or other intellectual property rights relating
thereto in any and all countries, including the disclosure to the Company of all
pertinent information and data with respect thereto, the execution of all
applications, specifications, oaths, assignments, recordations, and all other
instruments which the Company shall deem necessary in order to apply for,
obtain, maintain and transfer such rights and in order to assign and convey to
the Company, its successors, assigns and nominees the sole and exclusive rights,
title and interest in and to such Inventions, and any copyrights, patents, mask

agree that my obligation to execute or cause to be executed, when it is in my
power to do so, any such instrument or papers shall continue after the
termination of this Agreement until the expiration of the last such intellectual
property right to expire in any country of the world.  If the Company is unable
because of my mental or physical incapacity or unavailability or for any other
reason to secure my signature to apply for or to pursue any application for any
United States or foreign patents or copyright registrations covering Inventions
or original works of authorship assigned to the Company as above, then I hereby
irrevocably designate and appoint the Company and its duly authorized officers
and agents as my agent and attorney in fact, to act for and in my behalf and
stead to execute and file any such applications and to do all other lawfully
permitted acts to further the application for, prosecution, issuance,
maintenance or transfer of letters patent or copyright registrations thereon
with the same legal force and effect as if originally executed by me.  I hereby
waive and irrevocably quitclaim to the Company any and all claims, of any nature
whatsoever, which I now or hereafter have for infringement of any and all
proprietary rights assigned to the Company.

equipment, other documents or property, or reproductions of any aforementioned
