by Healtheon in compliance with BSC's specifications where Healtheon's method of
compliance has been specifically compelled by the terms of BSC's specifications;
or (ii) BSC's use of the Work Product in combination with any hardware or
software not furnished by or authorized by Healtheon hereunder, if such
combination is the cause of such claim and the Work Product is not material to
the claim, or any modifications which have been made by BSC if such modification
is the cause of the claim. In addition, Healtheon shall have no indemnity
obligation for claims of infringement resulting or alleged to result from BSC's
failure within a reasonable time frame to implement any replacement or
modification which conforms to the requirements of Section 11.4 herein. BSC
shall have no indemnity obligations for claims resulting from or alleged to
result from Healtheon's breach of any Third-Party Technology or Software rights
where appropriate consents, licenses and/or assignments were obtained and
provided to Healtheon and Healtheon failed to adhere to the terms of applicable
consents, licenses and/or assignments.

         11.3     Payment and Cooperation. Subject to the limitations set forth
in Section 11.2 above, the indemnifying party shall pay all losses, damages,
settlements, expenses, costs and reasonable attorneys' fees, incurred by the
indemnified party arising out of the matters set forth in Section 11.1 provided
that such payment shall be contingent on: (i) cooperation by the indemnified
party with the indemnifying party in the defense and or settlement thereof, at
the indemnifying party's expense; and (ii) allowing the Indemnifying Party to
control the defense and all related settlement negotiations. The indemnified
party shall give the indemnifying party prompt written notice of any such claim
to enable the indemnifying party to defend or mitigate the claim.

         11.4     Remedy. If, in the event of an infringement action pertaining
to the Work Product, including the Developed Applications, and/or Healtheon
Platform Software and BSC's use of the such Work Product and/or Healtheon
Platform Software is disrupted, Healtheon shall, at its option, (i) provide BSC
with access to software which is functionally equivalent to the infringing
elements of the Work Product and/or Healtheon Platform Software as applicable,
without additional charge; (ii) modify the infringing portions of the Work
Product and/or Healtheon Platform Software, as applicable, to avoid the
infringement; or (iii) obtain a license for BSC to continue use of such Work
Product and/or Healtheon Platform Software, as applicable, for the term of the
applicable license and pay, on an annual basis, if Healtheon elects not to
acquire a perpetual license, the additional fee required for such license(s).

         11.5     Sole Obligation. SECTION 11 SETS FORTH THE PARTIES' SOLE
OBLIGATION, AND THE SOLE RECOURSE AGAINST THE OTHER PARTY IN THE EVENT OF ANY
CLAIM OF INFRINGEMENT OF THIRD PARTY INTELLECTUAL PROPERTY RIGHTS.

         11.6     In the event that an error or omission by Healtheon as part of
the IT Services provided to BSC under Service Exhibit A has caused a BSC Client
solely to suffer actual damage and the BSC Client has received compensation from
BSC for the actual damage, and if the Management Committee determines that such
error or omission was the result of negligence or a failure to meet the
warranties set forth in Section 9.1 above, then the Management Committee shall
determine the percentage of such damages amount that shall be payable by
Healtheon, taking into consideration the degree to which such error or omission
was the cause of such damage in relation to other contributing facts and
circumstances, including, without limitation, the errors, omissions, or
negligence of BSC, and Healtheon shall pay to BSC such amount as determined by
the Management Committee. Healtheon's obligations under this Section 11.6 shall
be subject to the Limitation of Liability set forth in Section 10.2 above.

12.      TERM AND TERMINATION.

         12.1     Term. This Agreement shall continue for a fixed term of five
(5) years from the Effective Date (the "Term") unless terminated earlier under
the provisions of this Section 12 or by the mutual agreement of the parties. At
the end of each year of the Term, the parties shall review the state of this
Agreement and have the option to mutually agree to extend the Term for an
additional year. For example, the parties shall meet after the first year of
this Agreement and review the state of the Agreement. At that time, the parties
may mutually agree to extend the term of the Agreement to a term of six years
from the Effective Date. Notwithstanding the foregoing, the licenses granted in
Sections 5.1 and 5.2 shall have a perpetual term unless terminated earlier
pursuant to Section 12.3 or 12.4 or by the mutual consent of the parties.

         12.2     Termination for Convenience. Either party may terminate this
Agreement upon one year prior written notice to the other for any reason.
Promptly following the notice of termination, the parties shall use good faith
efforts to agree to a commercially reasonable transition plan which will enable
the parties to mitigate any on-going expenses during the notice period.

         12.3     Termination by Either Party for Default. If either party
defaults in the performance of any material provision of this Agreement, then
the non-defaulting party may give written notice to the defaulting party that if
the default is not cured within ninety (90) days of such notice the Agreement
will be terminated. If the non-defaulting party gives such notice and the
default is not cured during the ninety (90) day period, then the Agreement shall
automatically terminate at the end of that ninety (90) day period.

         12.4     Insolvency. Either party may terminate this Agreement by
written notice to the other, and may regard the defaulting party as in default
of this Agreement, if the defaulting party becomes insolvent, makes a general
assignment for the benefit of creditors, suffers or permits the appointment of a
receiver for its business or assets, becomes subject to any proceeding under any
bankruptcy or insolvency law whether domestic or foreign, or has wound up or
liquidated, voluntarily or otherwise.

         12.5     Effect of Termination. The provisions of Sections 7 (solely
with respect to Fees and other payments which were due and payable as of the
date of termination), 4, 8, 10, 11, and 13 (to the extent applicable) shall
survive the termination of this Agreement for any reason. All other rights and
obligations of the parties shall cease upon termination of this Agreement. In
the event of a termination, neither party shall be entitled to any refund of the
fees paid or cost incurred for the development performed hereunder. Provided
that this Agreement is not terminated by Healtheon pursuant to either Section
12.3 or 12.4 or by BSC pursuant to Section 12.2, upon termination, Healtheon
shall deliver to BSC a copy of each Developed Application, Additional
Application, Data Structure, and Database Information which has been completed
as of the date of termination or is under development, in source and object code
form, and the related technical and user documentation, and, in the event of the
exercise of BSC's option pursuant to Section 5.2, Healtheon shall deliver to BSC
a copy of the Healtheon Platform Software in object code form.

         12.6     Return of Materials. Within thirty (30) days after the
termination of this Agreement, each party shall return to the other, all
Confidential Information, and other material of any kind which is the property
of the other party.

13.      GENERAL.

         13.1     No Exclusivity or Restriction on Other Activity. Except as
expressly set forth in this Agreement, nothing herein shall preclude either
party from entering into agreements to obtain similar services or development
work from third parties or from providing similar services or development work
to third parties.

         13.2     Relationship of Parties. The relationship of the parties shall
be that of independent contractors. Neither party will represent that it has any
authority to assume or create any obligation, express or implied, on behalf of
the other party, or to represent the other party as agent, employee, or in any
other capacity, except as specifically provided herein.

         13.3     Binding Effect; Assignment. This Agreement shall be binding on
and inure to the benefit of the respective parties and their permitted
successors and assigns. Neither party shall transfer, assign, sublicense or
subcontract any right or obligation hereunder, except as expressly provided
herein. In the event of a change in control of a party hereto, such party shall
be permitted to assign this Agreement to the surviving or new corporation
acquiring all or substantially all of the business and assets of such party by
merger, acquisition, consolidation or otherwise, with the prior written consent
of the other party, which consent shall not be unreasonably withheld. Either
party may assign its rights under this Agreement to an entity which it controls,
with the prior written consent of the other party, which consent shall not be
unreasonably withheld. It shall not be unreasonable for a party to withhold its
consent if any proposed assignment would materially increase such party's
obligations under this Agreement or materially increase the scope of the other
party's rights (including but not limited to the grant of rights contained in
Section 5) or if such proposed assignee is a competitor of such party.

         13.4     No Waiver. Either party's failure to exercise any right under
this Agreement shall not constitute a waiver of any other terms or conditions of
this Agreement with respect to any other or subsequent breach, nor a waiver by
such party of its right at any time thereafter to require exact and strict
compliance with the terms of this Agreement.

         13.5     Notices. All notices or other communications which are
required or permitted to be given hereunder shall be in writing and shall be

in Section 365(n) of the Bankruptcy Code. Upon the commencement of a bankruptcy
petition involving either party, the other party shall be entitled to retain and
may fully exercise all rights and licenses available under the Bankruptcy Code,
subject to the fulfillment by the other party of its obligations under this
Agreement.

         13.12    Residual Information. Without prejudice to either party's

control (other than obligations for the payment of money or the maintenance of
confidentiality), including, but not limited to, acts of God, earthquakes, labor
disputes and strikes, riots, war, actions decrees of governmental bodies,

                                SERVICE EXHIBIT A
                                   IT SERVICES

This Service Exhibit A is subject to and incorporates the terms of the Master
Services, Development and License Agreement (the "Agreement") dated November
___, 1999 between Healtheon Corporation ("Healtheon") and Beech Street
Corporation ("BSC").

1.       Scope of Services. Healtheon will operate and maintain BSC's
information technology infrastructure and data processing functionality and
related services (collectively referred to as "IT Services"), including the
following types of services, as necessary and agreed to by the parties:

-        Maintain hardware operations

-        Maintain software infrastructure

-        Maintain data network(s)

-        Maintain desktop computing systems

-        Provide internal and external technical support

-        Provide project planning and management

-        Provide software installation

-        Provide hardware installation

-        Provide user technical support

-        Provide user training

-        Provide IT personnel management services

-        Provide IT consulting services

-        Provide custom software solution design and development services

2.       Term. The term of this Service Exhibit A shall commence on the
Effective Date of the Agreement and, unless earlier terminated as provided
herein, shall continue for the term of the Agreement. The parties will review
the terms of this Service Exhibit A within ninety days after the Effective Date
and determine whether the IT Services to be provided should be more fully
addressed in a mutually agreed-upon amendment hereto. Beginning June 30, 2000,
and on each six month anniversary thereafter, BSC will review the IT Services
provided hereunder, and, if BSC reasonably determines that such services do not
adequately meet the requirements set forth in this Service Exhibit A or amended
version thereof ("IT Requirements"), BSC may provide Healtheon with a written
notice identifying those aspects not meeting such IT Requirements, and stating
BSC's intent to terminate the Service Exhibit in six (6) months. If, by the end
of such six (6) month period, Healtheon fails to improve the IT Services such
that the IT Requirements are met, this Service Exhibit will automatically
terminate.

BSC reserves the right to terminate this Service Exhibit with 90 days written
notice.

3.       Third Party Technology and Software. In order to perform the Services
contemplated hereunder (but excluding Services relating solely to the Developed
Applications), BSC represents that Healtheon will need to have access only to
the third-party technology and software listed on Attachment A-1 which is
licensed and/or deployed by BSC (the "Third-Party Technology and Software"). BSC
hereby agrees to use commercially reasonable efforts to obtain, at its own
expense, all necessary consents, licenses and/or assignments which may be
necessary in order for Healtheon to perform such Services. Healtheon shall use
commercially reasonable efforts to cooperate with BSC to assist BSC in obtaining
any necessary consents, licenses and/or assignments to Third-Party Technology
and Software. During the term of this


                                    Page 15
<PAGE>   16

Agreement, BSC hereby grants to Healtheon a nonexclusive and nontransferable
right and license to use, modify and copy all technology and software owned by
BSC which is necessary for Healtheon to perform the Services.

4.       Fees. For IT Services performed hereunder, BSC will pay Healtheon the
associated direct expenses and management fee as set forth below:

         Direct Expenses: Healtheon shall charge BSC [*]% of Healtheon's
"direct" expenses associated with the IT Employees, including salary, and
benefits calculated at an assumed rate equal to [*]% of each IT Employee's
salary. "IT Employees" means those Healtheon employees or contractors whose
primary responsibility is the providing of IT Services hereunder at BSC's
facilities. Healtheon agrees that it will not charge BSC (i) any support
expenses, such as rent, phone, computing, office expenses for those IT
Employees; or (ii) any Healtheon "allocated" expenses, such as management,
administration, other overhead cost, etc., with respect to such IT Employees. In
the event that Healtheon decides to provide any of the IT Employees with
Healtheon stock options, Healtheon agrees that it will not charge BSC any
expenses associated with any such grants.

         Healtheon Management Fees: The management fees for the remainder of
1999 will reflect a monthly management fee of $[*]. The parties will negotiate
the management fee to be applied to the remaining term of this Agreement.

         The parties shall mutually develop a budget for the total fees and
expenses under this Service Exhibit and Healtheon shall make a reasonable
attempt to complete the services under this Service Exhibit within this budget.

5.       Ownership Rights. Except as otherwise provided in this Section 5, all
work product created by Healtheon for BSC under this Service Exhibit ("IT
Service Product") is the sole property of BSC. Healtheon acknowledges and agrees
that BSC shall have all proprietary rights to all IT Service Product including,
but not limited to, all technology of any nature whatsoever, all notes, records,
drawings, designs, inventions, improvements, developments, discoveries, and any
copyrightable material, and all patentable inventions, conceived, made or
discovered by Healtheon employees under this Service Exhibit, solely or in
collaboration with others, in the performance of the Services performed under
this Service Exhibit, including any derivative works of any of the foregoing.
Healtheon acknowledges and agrees that BSC shall have all proprietary rights in
and to the IT Service Product, including, without limitation, all copyrights,
patents and trade secret rights, all moral rights, all contract and licensing
rights, and all claims and causes of action of any kind with respect to any of
the foregoing, whether now known or hereafter to become known, and that BSC
shall have the sole and exclusive right to use, modify and exploit the IT
Service Product in any manner that BSC may choose. Notwithstanding the
foregoing, IT Service Product shall not include, and Healtheon shall have sole
ownership of all right, title, and interest in and to, all enhancements,
modifications, improvements, and derivative works of the Healtheon Platform
Software, the Developed Applications, and the Additional Applications (excluding
those Additional Applications owned by BSC), created by Healtheon employees in
their performance under this Service Exhibit, or created by or for BSC
("Healtheon Improvements"), and all intellectual property rights therein.
Healtheon agrees that the software currently under development by Dr. Ed Zalta
for BSC is solely owned by BSC. Subject to the terms and conditions of the
Agreement, the licenses granted to BSC under Section 5.2 of the Agreement shall
apply to Healtheon Improvements of the Healtheon Platform Software, and the
licenses granted to BSC under Section 5.1 the Agreement shall apply to Healtheon
Improvements of the Developed Applications. Healtheon shall not use or provide
to third parties any Healtheon Improvements of the Developed Applications.

                                SERVICE EXHIBIT B
                   PROVIDERWORKS APPLICATION DEVELOPMENT WORK

This Service Exhibit B is subject to and incorporates the terms of the Master
Services, Development and License Agreement (the "Agreement") dated November __,
1999 between Healtheon Corporation ("Healtheon") and Beech Street Corporation
("BSC").

1.       Development Work. Healtheon shall design, develop, test, and complete
Healtheon's ProviderWorks Application incorporating BSC's Repricing
Configuration. A "Repricing Configuration" for a particular entity means a
configuration of the application and associated database that is determined by
such entity's claim reimbursement schedules, and the repricing contracts between
such entity and its affiliated providers and payers. The specifications for the
ProviderWorks Application to be developed hereunder are described in Attachment
B-1 ("Specifications"), which is attached hereto for reference. The parties
shall jointly develop a mutually agreeable detailed project plan, which shall be
described in Attachment B-2 ("Project Plan"), which is attached hereto for
reference. The Project Plan shall describe, in a degree of detail reasonably
satisfactory to the parties, all tasks and responsibilities required for the
successful and timely completion of the development and delivery of the
ProviderWorks Application, including the projected costs. The ProviderWorks
Application incorporating BSC's Repricing Configuration shall be deemed a
"Developed Application" for purposes of the Agreement.

2.       Project Managers. The Project Managers shall coordinate the development
of the ProviderWorks Application. In addition, the Project Managers shall be
responsible for the development of the Project Plan, coordinating their
respective personnel and resources to satisfy their respective responsibilities,
administering Change Requests, and arranging for the transmission and receipt of
any deliverables, information and periodic status reports as required under the
Project Plan. From time to time during the term of this Agreement, each party
may replace its Project Manager with another person having equivalent authority
by providing written notice to the other party.

3.       Change Requests. From time to time prior to the completion of the
Development Work hereunder, BSC may propose changes to the Project Plan and/or
Specifications ("Change Requests"). Such Change Requests shall be submitted in
writing. Healtheon shall review the Change Request and advise BSC whether
Healtheon's assessment of and response to the Change Request will require
payment of fees by BSC to Healtheon. If a Change Request does not, in
Healtheon's sole opinion, require Healtheon's expenditure of materially more
time and effort, Healtheon shall agree to the change at no additional charge,
but may require adjustment of the time schedules. If such Change Request does
require, in Healtheon's sole opinion, Healtheon's expenditure of materially more
time and effort, Healtheon will provide BSC a cost estimate for implementing the
change and shall advise BSC of the impact on the ProviderWorks Application. No
such changes, however, shall become effective until a written amendment
specifying the change or changes is executed by authorized representatives of
both parties.

4.       Development Team. Healtheon shall provide an engineering team staffed
with up to forty engineers until the completion of the Development Work in
accordance with the Project Plan. In the event that the Project Plan require
additional personnel resources, the parties will revise the staffing commitments
hereunder.

5.       System Testing and Final Acceptance.

         5.1      Testing. In accordance with the Project Plan, the parties will
mutually agree upon a plan for testing the ProviderWorks Application ("Test
Plan"). Within fifteen (15) days following the completion of testing in
accordance with the Test Plan, BSC will give notice of its acceptance or
rejection of the ProviderWorks Application provided to BSC hereunder. BSC shall
accept the ProviderWorks Application if it substantially meets the
Specifications in all material respects. If BSC determines that the
ProviderWorks Application does not substantially meet the Specifications in all
material respects, then BSC shall notify Healtheon in writing of the
non-compliances identified by BSC. If BSC provides Healtheon with a notice of
non-compliance within such fifteen (15) day period, then within thirty (30) days
after its receipt of such notice, Healtheon shall correct the non-compliance and
document to BSC the corrective actions. Upon receiving such documentation of
corrective action, BSC shall immediately retest the ProviderWorks Application in
accordance with the Test Plan, and provide notice of acceptance or rejection as
set forth above. The foregoing testing and acceptance cycle shall be repeated up
to four (4) times before invocation of any other remedy in this Agreement by
BSC. BSC shall have been deemed to accept the ProviderWorks Application upon (i)
BSC's delivery to Healtheon of a written notice of acceptance, (ii) BSC's
failure to provide notice of rejection or acceptance within fifteen (15) days
following completion of testing under the Test Plan, or (iii) BSC's use of the
ProviderWorks Application other than for testing purposes.

         5.2      Rejection of ProviderWorks Application. Upon expiration of the
testing and acceptance process described in Section 5.1 above, if the
ProviderWorks Application fails to meet the Acceptance Criteria, BSC shall have
the option of either (i) accepting the ProviderWorks Application as it is then
currently implemented; or (ii) rejecting the ProviderWorks Application and
terminating this Service Exhibit. THESE RIGHTS OF ACCEPTANCE AND REJECTION
CONSTITUTE BSC'S SOLE REMEDY IN THE EVENT OF ANY FAILURE OF THE PROVIDERWORKS
APPLICATION TO MEET THE ACCEPTANCE CRITERIA. In the event BSC rejects the
ProviderWorks Application under this Section 5.2, the ProviderWorks Application
shall not be licensed under Sections 5.1 and 5.3 in the Agreement, and BSC shall
promptly return all copies thereof to Healtheon.

6.       Ongoing Development. Following completion of the ProviderWorks
Application under Section 1 above, Healtheon will continue to provide, upon
BSC's request, services for the further development of the ProviderWorks
Application on a time and materials basis.

7.       Revenue Sharing by Healtheon. Healtheon shall pay to BSC the Applicable
Percentage (as defined in this Section 7) of Net Revenues (as defined below)
with respect to ProviderWorks On-Line Services received from Healtheon's
ProviderWorks customers. "Net Revenues" shall mean the revenues received by
Healtheon from a Healtheon ProviderWorks customer for ProviderWorks On-Line
Services less any amounts paid or owed by Healtheon to anyone on account of the
revenues received, including but not limited to taxes, royalties, leased network
fees, broker fees, commissions paid to outside third parties, subcontractor
vendor fees and other such reasonable and customary fees as may apply from time
to time. The "Applicable Percentage" with respect to Healtheon's ProviderWorks
On-Line Services shall be [*] percent ([*]%) if the customer is a Qualified
Healtheon Customer, or [*] percent ([*]%) otherwise. A customer will be
designated as a "Qualified Healtheon Customer" if BSC generated the lead,
participated in sales calls, demonstrations, and negotiations, and brought the
sale by Healtheon to such customer to conclusion, such designation to be
determined by the parties on a case-by-case basis. Healtheon's obligation under
this Section 7 shall continue for the term of this Service Exhibit B for so long
as BSC

continues to use its best efforts to market the ProviderWorks On-Line Services,
and to pay the Development Services fees due hereunder.

8.       Limitation on Right to Modify. Nothwithstanding Section 5.1 of the
Agreement, BSC may use the ProviderWorks Application solely in a BSC Repricing
Configuration, and may not reconfigure the ProviderWorks Application for a third
party Repricing Configuration.

9.       Fees and Expenses. For Development Work performed hereunder, BSC will
pay Healtheon development fees at a rate of $[*] per hour. The parties shall
mutually develop a budget for the total fees and expenses under this Service
Exhibit and Healtheon shall make a reasonable attempt to complete the
Development Work within this budget.
