                                    RECITALS

AvantGo operates an Internet service (the "AG Service") that facilitates
delivery of information obtained over the Internet through handheld devices.

The AG Service delivers information in several general interest categories and
specific subcategories each of which provides content supplied by individual
content providers.

AvantGo and McKesson have entered into an Amendment to License Agreement of even
date herewith under which McKesson has acquired a license to utilize certain
AvantGo software (the "Licensed Software") in the conduct of its business,
including offering information services to its customers.

The parties want McKesson to develop and manage a Health Category available
through the AG Service.

The parties intend to share revenues generated by the Health Category, as well
as revenues generated by similar activities conducted by McKesson using the
AvantGo software on behalf of McKesson's customers, but do not intend to share
revenues arising from the operations of their respective core businesses.

The parties wish to set forth their understanding with regard to the foregoing
matters in this Agreement.

NOW, THEREFORE, the parties agree as follows:

          -------------------                                                 
Health Category, as follows.

          2.1.1  Channels. McKesson's responsibilities will include exclusive
                 --------                                                    
management of Content within the Health Subject Areas, except as provided in
section 3.5. McKesson will assume management of Channels within the Health
Subject Areas promptly after the Effective Date and following orientation by
AvantGo concerning the AG Service. Content Partner Agreements in existence prior
to the Effective Date of this Agreement for Channels in Health Subject Areas may
continue in effect only until they first expire or otherwise terminate, after
which time any continuation will be within McKesson's sole discretion. McKesson
will determine appropriate Channels within the Health Subject Areas to add to or
delete from the Health Category. AvantGo may request that particular Content
Providers or Channels be included in the Health Category, and McKesson will
consider in good faith accommodating such requests.


                                    Page 2

 
AvantGo will cooperate as reasonably requested by McKesson in connection with
McKesson's Health Category management and the allocation of Content to
Subscribers.

          2.1.2   Content Providers. McKesson will be responsible for all
                  -----------------                                      
interaction with Content Providers relating to the scope and nature of the
Content (as distinct from technical delivery of the Content). McKesson will
include and exclude Content and Content Providers for the Channels in McKesson's
sole reasonable discretion, and will communicate its determinations to AvantGo
in a manner reasonably requested by AvantGo. Revenue will be collected and
allocated in accordance with section 6 below.

          2.1.3   Agreements. McKesson will negotiate all agreements with
                  ----------
Content Providers for the supply of Content in the Health Category. McKesson
will include in such agreements technical requirements reasonably requested by
AvantGo. McKesson will obtain from Content Providers terms no less protective of
AvantGo than those at Exhibit 2.1.3, and the agreement will state that AvantGo
is a third party beneficiary of such terms. McKesson may extend to Content
Providers promises and benefits on behalf of AvantGo no more burdensome to
AvantGo than those specified in Exhibit 2.1.3. To the extent of the provisions
in Exhibit 2.1.3 only, Content Providers shall be third party beneficiaries of
this Agreement. In McKesson's reasonable discretion, such agreements will
provide for compensation which may include, without limitation, any or all of
[******].

          2.1.4   McKesson Content. McKesson may itself supply Content for one
                  ----------------
or more Channels under the terms of this section 2.1.4 ("McKesson Content").
Subject to its obligation to share revenue set forth in Section 6.2, McKesson
will not be obliged to pay fees for placement of McKesson Content on the AG
Site. Notwithstanding the foregoing, if McKesson Content receives preferred
placement or is otherwise specially featured such that McKesson would charge
another Content Provider additionally for preferred treatment, then McKesson
will pay AvantGo [******].

     2.2  Advertising. Except as provided in section 2.2.1, McKesson will have
          -----------                                                         
the sole right and responsibility to enter into agreements for advertising and
other promotions in the Health Category, provided that such capabilities are
available and offered through the AG Service and within the technical
capabilities of the AG Service. McKesson will confer with AvantGo on technical
matters relating to Health Category advertising, including but not limited to
targeting, the use of cookies and other visitor promotional and solicitation
tools and techniques, and the requirements of third party advertising brokers
and other vendors.

          2.2.1   AvantGo Network. Subject to this section 2.2.1, AvantGo may
                  ---------------                                            
invite Content Providers in the Health Category to participate in an "AvantGo
Network" under which

requested with respect to the omitted portions.

                                    Page 3

 
advertisements are placed on various channels in the AG Service. To the extent
reasonably practical from a technical perspective, McKesson may decline to allow
the placement of some or all such advertising on such basis as it reasonably
considers appropriate, including but not limited to alternative advertising
sales opportunities or avoiding excessive advertising clutter. Revenue derived
from the portion of such advertising placed in the Health Category, allocated to
the Health Category on the basis of impressions or such other criteria as the
parties agree, will be included as revenue shared under this Agreement.

          2.2.2   Subcontracts. McKesson may subcontract the sale, serving and
                  ------------                                                
other aspects of advertising in its reasonable judgment.

     2.3  Technical Contacts. McKesson and AvantGo will cooperate to allow
          ------------------                                              
Content Providers to communicate directly with AvantGo concerning technical
matters related to the supply and distribution of Content.

     2.4  Non-Circumvention. Neither party will enter into deals with
          -----------------                                          
prospective Content Providers which are intended to circumvent, in whole or in
part, the revenue sharing arrangements hereunder. The occurrence of any such
arrangement shall constitute a breach of this Agreement.

3.  AvantGo Responsibilities

     3.1  Hosting.
          --------

          3.1.1   Category Hosting. AvantGo will operate the AG Service and host
                  ----------------                                              
the Health Category as part of the AG Site and in accordance with this
Agreement. Except to the extent inconsistent with this Agreement, AvantGo will
maintain performance of the AG Site to be equal to or better than the
performance of other reasonably high-quality consumer oriented sites generally
with respect to uptime, responsiveness, and other common factors affecting site
performance.

          3.1.2   Technical Support. All Content must conform to the Style
                  -----------------
Guide. AvantGo will use its commercially reasonable efforts to respond to all
electronic mail requests received during normal business hours within twenty-
four (24) hours, and will furnish such technical support to Health Category
Content Providers as it furnishes to other Content Providers generally. AvantGo
will provide additional support to Content Partners, in AvantGo's sole
discretion, subject to AvantGo's then-current time and materials rates. AvantGo
will continue to provide the "Developer Corner" area that is available to
Content Providers and McKesson technical personnel on the site currently located
at http://corp.avantgo.com/DevCorner/.

          3.1.3   Site Operation and Navigation. AvantGo will undertake
                  -----------------------------                        
commercially reasonable efforts to make the AvantGo Site continuously available
on the Internet, excluding reasonable scheduled maintenance periods. AvantGo
will not prevent or impede back channel and other Interact site and content
navigation generally available through Web browsers.

          3.1.4   Subscriber Support. AvantGo will provide all technical support
                  ------------------                                            
to Subscribers to the Health Category as part of its Subscriber support for the
AG Service generally. Subscriber support will be equal to or better than that
provided to users of non-Health Category channels.

     3.2  Content Review. McKesson and AvantGo will cooperate to remove any
          --------------                                                   
Content that is defamatory, obscene, infringing, deemed hate speech, unlawfully
invasive or in any other


                                    Page 4

 
way unlawful, or that encourages violence, or otherwise is in violation of the
Content Partner Agreements.

     3.3  Promotion. AvantGo and McKesson will advertise and promote the Health
          ---------                                                            
Category Channels and their Content, including but not limited to their launch.
AvantGo promotion will be no less prominent than that typical of its
advertisement and promotion of other Categories, Channels and Content available
through the AG Service in general.

     3.4  Reports. AvantGo will provide monthly reporting to McKesson at the end
          -------                                                               
of the month of the total number of Subscribers to each Health Category Channel,
and such other information reasonably available to AvantGo as McKesson
reasonably requests. If AvantGo will incur more than minimal costs or charges to
generate information that is not otherwise available, it will so advise McKesson
in advance and McKesson will reimburse AvantGo or withdraw the request.

     3.5  Non-Revenue Content. AvantGo may with McKesson's consent add Content
          -------------------                                                 
in a Health Subject Area that does not generate revenue. Such added Content may
be placed within or outside the Health Category as the parties agree, and may be
added in order to increase usage of the Health Category or the AG Service, or
for other purposes which benefit the Health Category or the AG Service
generally. McKesson may decline some or all such added Content on such basis as
it reasonably considers appropriate, taking into consideration the success and
popularity of the Health Category as a whole, including but not limited to the
basis that it conflicts with agreements with Content Providers or with actual or
proposed negotiations with potential Content Providers, but McKesson will not
unreasonably reject such added Content.

     3.6  Exclusivity. Except as expressly provided in sections 2.2.1 and 3.5,
          -----------                                                         
McKesson has the exclusive right to obtain or provide, as the case may be, the
supply of Content for the Health Category. AvantGo will not designate any
channel or obtain, provide or distribute content that, in the aggregate over
time, is primarily within one or more of the Health Subject Areas. AvantGo will
not solicit or distribute through the AG Service advertising for information,
products or services in the Health Subject Areas, other than that supplied
through McKesson. No Category other than the Health Category will contain in its
title the terms "health", "wellness", "health care", "medical", or "medicine" or
any combination or synonyms of such terms.

4.  Mutual Responsibilities

     4.1  Principal Contacts; Meetings. Each party will appoint a person to be
          ----------------------------                                        
the principal contact with the other for matters relating to this Agreement
(each, a "Manager"). At least monthly, or at such other times as the parties
agree, the Managers will meet to review the status of the activities relating to
this Agreement and to resolve any outstanding issues. Should the Managers be

specifying the issue of concern, both Managers will arrange to have more senior
officers of each party meet to resolve the issue.

the principal contact for technical matters related to operation of Channels and
the AG Service, who will be available during business hours to assist or meet
with McKesson. The Technical Contact will also assist Content Providers to the
same extent as typically provided to other Content Providers. The Technical
Contact may be, but need not be the same person as the Manager appointed by
AvantGo as its principal contact.

McKesson HBOC"). It will include the phrase and term in its listing with other
Categories and in any and all other places on the AG Site in which it appears.
The Health Category will be listed no less prominently than is typical of any
other AG Service Category, excluding special short-term promotions. Without
limiting the foregoing, the Health Category will typically be listed "above the
fold" if any Category is typically listed "above the fold". To the extent that
AvantGo is reasonably able to do so, it will feature the McKesson logo (or such
other logo as McKesson substitutes) in the Health Category listing of the Health
Category pages.

          4.2.2   Logo and License. McKesson will furnish AvantGo its logo in
                  ----------------

                           -----------------
conditions of this Agreement, McKesson hereby grants AvantGo a limited,
worldwide, royalty-free, non-exclusive license to display its name and logo (the
"McKesson Marks") as described in this section 4.2 during the term of this
Agreement. Any such use of the McKesson Marks will be consistent in all respects
with then current trademark usage guidelines that McKesson may communicate to

as requested by McKesson from time to time, all such rights and interests to

                          -----------------                                     
of this Agreement, AvantGo hereby grants McKesson a limited, worldwide, royalty-
free, non-exclusive license to display its name and logo (the "AvantGo Marks")
as described in this section 4.2 during the term of this Agreement. Any such use
of the AvantGo Marks will be consistent in all respects with then current
trademark usage guidelines that AvantGo may communicate to McKesson from time to

any names similar to the McKesson Marks in connection with the AG Services or
otherwise, nor use names or marks that could reasonably be construed to identify
McKesson or its products or services, except in connection with the Health
Category and Content provided through McKesson. AvantGo will not use or
authorize others to use, in connection with the Health Category, trademarks or
service marks of any other party without McKesson's consent. Nothing contained


                                    Page 6

 
in this Agreement restricts AvantGo's ability to sell AvantGo Enterprise Server
products to current or prospective customers.

     4.3  Launch. In general, the parties will use diligent efforts to make the

Health Category available on the AG Site, including but not limited to all
Content necessary to make active Channels available. In particular, but without
limiting the foregoing, AvantGo will diligently implement all technical
requirements necessary and appropriate for the availability and distribution of
Content through the Health Category. Each party will notify the other in writing
of any material delay in the expected completion of its responsibilities.

5.  Ownership

     5.1  Party Technology. As between the parties, each party will retain
          ----------------                                                
ownership and all rights in and to any and all U.S. and foreign intellectual
property of any kind or nature in or comprising all software and other
technology that is used in connection with this Agreement. However, any such
software or technology that is conveyed by one party to the other for the
express written purpose of performing this Agreement will be deemed to be
licensed on a nonexclusive, fully-paid, revocable and nontransferable basis, for
the term of this Agreement, but excluding in all events the right to create
derivative works of, distribute or sublicense such software or technology.
Nothing in this Agreement gives either party any other right, title or interest
in or to the software or other technology of the other party. The provisions of
this section do not apply to jointly developed technology described in the
following section.

     5.2  Jointly Developed Technology. It is the intent of the parties that no
          ----------------------------                                         
intellectual property in respect of technology (as distinct from Content as
provided in the following paragraph) of any kind or nature be created and owned
by them jointly. However, to the extent that their joint activities result in
technology or related intellectual property that is deemed under applicable laws
to be jointly developed and jointly owned by them, the parties will affirm such
ownership in writing. The parties will cooperate, as either of them may
reasonably request, in the protection of any such jointly owned intellectual
property, by registration, prosecution and otherwise. However, neither party
will be required to be a named plaintiff or to expend money in connection with
such protection. If such a protection action for which the parties may be joint
plaintiffs or applicants or any related joint and equal expenditure of money is
proposed by one party, and the other party refuses to expend such money or be a
joint plaintiff, and if the proposing party proceeds with any such protection
action as plaintiff or bearing all such expense, then such party may retain all
commercial and other rights specifically arising or maintained as a result of
the action, including but not limited to any right to receive and retain any
damages awarded or agreed. Neither party shall use or authorize any third
parties to use any jointly owned technology or related intellectual property in
connection with the publication or distribution of Content in the Health Subject
Areas other than Content distributed pursuant to this Agreement. Notwithstanding
the provisions of this section 5.2, a party may propose and the parties may
mutually agree to other arrangements concerning cooperative efforts in
developing and owning technology.

     5.3  Content. Content Providers will retain any ownership interest they may
          -------                                                               
have in any and all Content they provide for distribution under this Agreement,
unless they agree otherwise in writing. AvantGo and McKesson each will retain
its respective ownership of Content. Each party will be deemed to license to the
other party, as and to the extent reasonably necessary or useful in the
performance of this Agreement, on a nonexclusive, fully-paid, irrevocable and


                                    Page 7

 
nontransferable basis, for the term of this Agreement, any and all copyrighted
material that is provided to the licensee party for distribution through, or in
connection with the promotion of, the Health Category. It is the intent of the
parties that no intellectual property of any kind or nature in respect of
Content (as distinct from software and other technology as provided in the
preceding paragraph) be created and owned by them jointly. However, to the
extent that their joint activities result in Content or related intellectual
property that is deemed under applicable laws to be jointly developed and
jointly owned by them, the parties will affirm such ownership in writing. The
parties will cooperate, as either of them may reasonably request, in the
protection of any such jointly owned Content and intellectual property, by
registration, prosecution and otherwise. However, neither party will be
required to be a named plaintiff or to expend money in connection with such
protection. If such protection action for which the parties may be joint
plaintiffs or applicants or any related joint and equal expenditure of money is
proposed by one party, and the other party refuses to expend such money, and if
the proposing party proceeds with any protection such action as plaintiff or
bearing all such expense, then such party may retain all commercial and other
rights specifically arising or maintained as a result of the action, including
but not limited to any right to receive and retain any damages awarded or
agreed. In all events, neither party shall use or authorize any third parties to
use, publish or distribute any jointly owned Content or related intellectual
property in connection with any publication or distribution of content except
pursuant to this Agreement. Notwithstanding the provisions of this section 5.3,
a party may propose and the parties may mutually agree to other arrangements
concerning cooperative efforts in developing and owning Content.

     5.4   Subscriber Data. McKesson may retain for its exclusive use any data
           ---------------                                                    
concerning Subscribers which it obtains from Content Providers. Neither party
will supply personally identifiable Subscriber data to third parties without the
Subscriber's consent, except that a party may without consent supply personally
identifiable Subscriber data to a third party vendor, contractor or other entity
to assist the party in its performance of functions related to the AG Service or
other functions internal to the party, provided the third party shall have
agreed to use personally identifiable Subscriber data for no other purpose.

6.  Compensation

     6.1  Costs. Each party will bear its own costs in performing this
          -----                                                       
Agreement.

     6.2  Revenue Sharing. Health Category revenue received by either party as
          ---------------                                                     
well as any revenue received by McKesson for Content offered using the Licensed
Software on McKesson's servers running the AvantGo Software (collectively, the
"Shared Revenue") will be divided by the parties as set forth on Exhibit 6.2.
Shared Revenue shall include, but shall not be limited to: [******].
Notwithstanding the foregoing to the contrary, Shared Revenue shall not include 
[******]. For this calculation, revenue includes all money and the monetary
equivalent of non-monetary consideration actually received. A party will notify
the other any time payment is to be in the form of non-monetary consideration,
it shall

obtain prior agreement of the other party as to the value of the non-monetary
consideration for revenue sharing hereunder, and shall pay the other its
proportionate share in money.

     6.3  Payment Terms. Shared Revenue payments will become due for each
          -------------                                                  
calendar month during which a party receives revenue. AvantGo will report
advertising and other revenue received on account of the Health Category no
later than the 15th day of the following month. By the end of that following
month McKesson will report to AvantGo the total Shared Revenue received by the
parties and the revenue share amount due from McKesson to AvantGo, which payment
will accompany the report. If for any month the net amount of Shared Revenue is
an amount payable by AvantGo to McKesson, then promptly upon receiving the
McKesson report (but in no event more than 30 calendar days thereafter) AvantGo
will remit the amount due. Each party's report will show the nature and source
of revenues, identify the name and date of the contract which gives rise to the
fee payment from the third party and such other detail as the patties agree, but
in any case reasonable detail. Payments not made when due will bear interest
until paid at the lesser rate of [******]% per month or the maximum rate allowed
by law.

     6.4  Audit Rights. Either party may audit the relevant books and records of
          ------------                                                          
the other party necessary for determining revenue and amounts payable in
connection with this Agreement for any period not previously audited. The audit
will be by nationally recognized auditors reasonably acceptable to the other
party. Any such audit will be subject to reasonable notice given to the party
being audited. The audit will take place during the audited party's normal
business hours and will be conducted in a manner that minimizes disruption to
the audited party's normal business activities. The audited party will provide
reasonable facilities for the audit or allow the original books and records to
be taken off premise by the auditors or copied and taken off premises for the
limited purpose of the audit. The audited party may condition the audit upon
receiving the auditors' written promise in a form acceptable to the audited
party that information discovered in the course of the audit will be kept
confidential and only the amount of any overpayment or underpayment will be
disclosed to the auditing party. The auditing party will bear the cost of the
audit. However, if the audit discloses any underpayment of five percent (5%) or
more for the audit period, then the audited party will pay the reasonable costs
of the audit within forty five (45) days after receipt of invoice and reasonable
cost documentation from the auditing party. Each party will keep records and
books of account for at least three (3) years from the date of the relevant
recordable event.

7.  Confidential Information

          -------------                                                      
party the other's Confidential Information except as expressly permitted in this
Agreement, and (ii) will take all reasonable measures to maintain the
confidentiality of the other party's Confidential Information in its possession
or control, but in no event less than the measures it uses to maintain the
confidentiality of its own information of similar importance.

     7.2  Legal Process. If a party is required by subpoena or other mandatory
          -------------                                                       
process to disclose Confidential Information of the other party, it will give
the other party a copy of the process promptly upon receipt and cooperate with
the other party, at that party's expense, in reasonable efforts to defend
against disclosure.

     7.3  Copies of Content Provider Agreements. Within 30 days of execution of
          -------------------------------------                                
any Content Provider agreement, McKesson will deliver a copy to AvantGo. The
Content Provider agreement will be Confidential Information under this
Agreement.

     8.3  Disclaimers. Except as expressly set forth in this section 8, NEITHER
          -----------

Protected Party's defense costs, and the Indemnifying Party will make diligent
efforts to obtain appropriate relief. A Protected Party will provide (x) prompt
notice of any such claim, (y) the Indemnifying Party sole control over the
defense and settlement of the claim, and (z) reasonable cooperation and
assistance to the Indemnifying Party, at the Indemnifying Party's expense, to

reasonable control, such as acts of God, war, riot, embargoes, earthquake, acts
