(such as excess electrical, overtime HVAC, damage expenses, etc.) and incurred
at Subtenant's request or otherwise allocable or attributable to the Subleased
Premises.  All Additional Rent shall be payable by Subtenant to Sublandlord at
the time and in the same manner such payments are due by Sublandlord under the

all the Landlord's obligations under the Lease and that Sublandlord shall not be
obligated to provide any services to Subtenant or otherwise perform any
obligations in connection with this Sublease, and (ii) Subtenant shall not be

    6.   Default.  Any act or omission by Subtenant that would constitute a
         -------

provided in the Lease, be deemed a default by Subtenant under this Sublease.  In
addition, any failure by Subtenant to pay Rent when due (and the continuance of

or any failure by Subtenant to perform any other obligations required under this
Sublease, shall be deemed a default hereunder.  Any such default by Subtenant
shall entitle Sublandlord to exercise any and all remedies available to Landlord

without interference by Sublandlord or anyone claiming by, through or under
Sublandlord.  Sublandlord shall comply with its obligations under the Lease.
Sublandlord will use reasonable efforts to enforce Landlord's obligations under
the Lease, but if Sublandlord chooses not to pursue an action to enforce any of
Landlord's obligations but Sublandlord desires to enforce such obligations,
Sublandlord will assign its rights to Subtenant and will cooperate with
Subtenant's efforts to enforce such obligations so long as such enforcement
efforts are at Subtenant's sole expense and Subtenant indemnifies Sublandlord
from any damages, claims or expenses resulting from such enforcement effort or
Sublandlord's cooperation therewith.

    8.   Insurance and Indemnities.  Subtenant hereby agrees to indemnify and
         -------------------------

         -------------------------

                                    FORM OF

                Intercompany Systems/Network Services Agreement

     This Intercompany Systems/Network Services Agreement (the "Agreement") is
between National Data Corporation, a Delaware corporation ("NDC" or "Provider"),
and Global Payments Inc., a ___________ corporation ("Global" or "Recipient")
(Global and NDC are each referred to as a "Party" and both are referred to as
the "Parties"), and is dated as of and is made effective as of _____________,
2000 (the "Effective Date").

                                  Background

     Prior to the Effective Date, NDC had two primary areas of business, the
processing of  electronic payments and related information transactions (the
"eCommerce Business") and the processing of Healthcare provider claims and
related transactions among health care providers and health care insurers as
well as providing Healthcare data base information. (the "Health Business")

     The Board of Directors of NDC has determined that it is in the best
interests of NDC and its shareholders for NDC to transfer and assign to Global
the capital stock of National Data Payment Systems, Inc., Global Payment Holding
Company, NDC Holdings (UK) Ltd., Merchant Services U.S.A. and their respective
subsidiaries (the "NDC Global Subsidiaries") that hold all of the assets and
liabilities that currently constitute NDC's Global business and a 0.85% general
partnership interest in GPS Holding Limited Partnership as a contribution to the
capital of Global and to receive in exchange therefor shares of Global common
stock, and to thereafter make a distribution (the "Distribution") on a date (the
"Distribution Date") to the holders of NDC common stock of all of the
outstanding shares of Global common stock at the rate of __ share of Global
common stock for every __ share of NDC common stock outstanding pursuant to a
Distribution Agreement, dated as of the date hereof, between NDC and Global (the
"Distribution Agreement"). The Parties intend that the transactions described in
the Distribution Agreement will be effective at the Effective Time (as that term
is defined in the Distribution Agreement). Upon the Effective Time, NDC's
business will be the Health Business, and Global's business will be the
eCommerce Business.

     Although the transactions provided for in the Distribution Agreement and
the Ancillary Agreements (as that term is defined in the Distribution Agreement)
will provide for the separation of NDC and Global into separate and distinct
entities and the substantial separation of their operations, and although the
Parties had, prior to the Effective Date, begun (and in some cases, completed)
the separation of certain computer system and network system functions, other
computer systems and network activities presently shared by the Parties, such as
the network of interrelated Tandem computers and related devices and systems
(the "Tandem System"), and the telecommunication contracts and related devices
and systems (the "Telecom System") that serve both the Health Business and the
eCommerce Business should not be separated as of the Effective Date for economic
reasons for both companies.

     Accordingly, the Parties deem it to be appropriate and in their best
interests in connection
<PAGE>

with the Distribution that NDC shall provide to Global certain services upon the
terms and conditions of this Agreement for the period provided for herein and
that Global will reimburse NDC for such services, on an allocated cost basis,
plus certain fees for administrative costs.

                             Terms and Conditions

     Now, Therefore, in consideration of the mutual promises contained herein
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the Parties hereto agree as follows:

               ARTICLE 1  Definitions and Rules of Construction

Section 1.1  Terms Defined in the Agreement

     An index of terms defined in the body of the Agreement is attached hereto
as Exhibit 1.01--Index of Terms Defined in the Agreement.

Section 1.2  Rules of Construction

     In this Agreement, unless the context requires otherwise, the singular
shall include the plural and vice versa.  The words "including," "includes" or
"included," shall be deemed to be followed by the words "without limitation."

                       ARTICLE 2  Provision of Services

     (a)  "Services" means the services described (i) in Addendum I--Telecom
Services (the "Telecom Services," which term refers to both the Telecom Carrier
Contract Services described therein (the "Telecom Carrier Contracts Services")
and the Telecom Support Services described therein (the "Telecom Support
Services")); (ii) in Addendum II--Tandem Services (the "Tandem Services"); (iii)
in Addendum III--Transition Services (the "Transition Services"); and (iv) in
Addendum IV--Ad Hoc Services (the "Ad Hoc Services").

     (b)  Starting on the Effective Date and continuing during the Term,
Provider shall provide the Services to, and perform the Services for, Recipient,
subject to the terms and conditions of this Agreement.

     (c)  There may be functions, responsibilities, activities and tasks not
specifically described in this Agreement which are required for the proper
performance and provision of the Services and are an inherent part of, or a
necessary sub-part included within, the Services.  If such functions,
responsibilities, activities and tasks are determined to be required for the
proper performance and provision of the Services, or are an inherent part, or a
necessary sub-part included within, the Services, such functions,
responsibilities, activities and tasks shall be deemed to be implied by and
included within the scope of the Services, to the same extent and in the same
manner as if specifically described in this Agreement.  Each such determination
shall be made by agreement of the Parties or resolved pursuant to the dispute
resolution provisions of Article 15 hereof.

                                       2
<PAGE>

     (d)  During the Term, each Party may exercise control over some portion(s)
of the facilities to be used to provide and perform the Services for Recipient.
Each Party shall provide the other Party and its employees, agents and
representatives reasonable access to such portion(s) of the facilities as
necessary or appropriate for the performance, delivery and use of the Services
and for the operation, maintenance, upgrade, support and use of any other
hardware, software and other resources owned or leased by either Party and
located in the facilities.

                        Article 3  Nature of Engagement

     (a)  During the Term, Provider will be the exclusive provider to Recipient
of the Tandem Services (the "Tandem Exclusive"), subject to termination of the
Tandem Exclusive upon any termination of this Agreement pursuant to Article 7
hereof, and with the exception that the Recipient may engage one or more third
parties to perform, or may itself perform, services in the nature of Telecom
Support Services in connection with its own contracts with telecommunications
carriers permitted by this Agreement.

     (b)  Notwithstanding the foregoing, the Tandem Exclusive shall not prohibit
Recipient from itself performing or from causing third parties to perform and
deliver to Recipient services similar or identical to the Tandem Services,
provided that such additional services are provided or delivered by using a
technology platform other than a platform of a type that was used by Provider on
the Effective Date to provide and deliver the Tandem Services hereunder.
Accordingly, Provider acknowledges that, during the Term, Recipient may
purchase, lease, develop, construct and/or build a front-end processing system
and/or separate technology platform whose performance and functionality is
substantially similar to the Tandem System provided that such new front-end
processing system or technology platform is not a platform of the type that was
used by Provider on the Effective Date.  Further, Recipient may, during the
Term, use any such system purchased, leased, developed, constructed and/or built
by it to perform services similar or identical to the Tandem Services for and on
behalf of Recipient or any of its customers, subject to Recipient's minimum
volume commitments for the Tandem Services.  Additionally, the Tandem Exclusive
(i) shall not apply to Recipient's cash management business and operations, (ii)
shall not require any corporation, business unit, business division, or other
entity acquired by Recipient during the Term whether by merger, consolidation or
otherwise to use the Tandem Services, and (iii) shall not require any
corporation, business unit, business division, or other entity that acquires
Recipient during the Term whether by merger, consolidation or otherwise to use
the Tandem Services (but in such case the Tandem Exclusive will continue to
apply to Recipient, and Recipient shall be required to obtain the Tandem
Services from Provider).

                        Article 4  Allocation of Costs

     All costs incurred by Provider in connection with the provision of the
Services will be allocated between the Parties as described in the body of this
Agreement or in Addendum V--Allocation of Costs.  Costs will be estimated and
allocated on a fiscal year basis, based on the process described in Addendum V--
Allocation of Costs.

     Recipient acknowledges and agrees that Provider will incur both fixed and
variable costs

                                       3
<PAGE>

and make commitments to incur such costs, including personnel, equipment and
other contractual commitments, based on the volume of Telecom Carrier Contract
Services or Tandem Services of Provider and Recipient which are projected as
part of the 12-month rolling forecasts described in Addendum VII and referred to
in Addendum V (the "Projected Volumes"). If, for any reason, including reasons
beyond Recipient's control, such as a loss of customers, (i) Recipient's actual
use of Telecom Carrier Contract Services or Tandem Services is less than the
Projected Volumes, or (ii) Recipient expects to require a lower volume of
Telecom Carrier Contract Services or Tandem Services than the Projected Volumes,
Recipient must notify Provider of such losses (or anticipated losses) within
thirty (30) days after the date that Recipient has notice of such losses or
anticipated losses. Notwithstanding any such lower volumes during a fiscal year,
no reductions in allocations for the fixed costs of Provider or charges made in
accordance with such fixed cost allocations will be made for such fiscal year.
Provider will, however, use commercially reasonable efforts to eliminate the
variable costs associated with the provision of the Services and the attendant
reduction in costs will be shared by the Parties on a pro rata or other
equitable basis.

     All fixed costs, including budgeted costs for a fiscal year and any other
costs actually incurred for a fiscal year (for example, unbudgeted raises for
personnel that were planned for such fiscal year, unbudgeted new hires required
to perform the Services, or unbudgeted increases in license fees for Third Party
Software used to provide Services) shall be considered minimums for such fiscal
year.  Provider will, however, use commercially reasonable efforts to reduce the
fixed costs during the Term and, to the extent that Provider is able to achieve
a reduction in costs, the reductions in costs will be shared by the Parties on a
pro rata or other equitable basis.

               Article 5  Acknowledgment of Unique Relationship

     The Parties acknowledge and agree that the relationship established by this
Agreement, which has been established as a result of the fact that, prior to the
Distribution Date, the Services were provided to the Health Business and the
eCommerce Business from a unified system, is unique.  The Parties further
acknowledge and agree that, after the Distribution Date, (i) the Tandem Services
will be provided to Recipient by Provider using the same integrated, networked
computer system that provides similar services to Provider's business; (ii) the
Telecom Carrier Contract Services obtained for Recipient are and will be managed
and supervised as part of similar services obtained for Provider's business
using the same integrated, networked system; (iii) the costs to both Parties of
obtained telecommunications carriage services will likely increase if the
Parties are unable to take advantage of their combined volume needs; and (iv)
because the Parties are sharing systems, any diminution of quality, services
levels, reliability, uptime of systems or similar matters, including the Telecom
Carrier Contract Services and the Tandem Services, will impact both Parties
equally.  Finally, the Parties acknowledge and agree that the Services are not
being provided by Provider in order to make a profit, but instead, the fees and
expenses of providing the Services are based on an allocation of costs as more
fully described in Addendum V hereto.

                                       4

                       Article 6  Invoices and Payments

Section 6.1  Invoices

     Provider will provide Recipient monthly invoices which shall list with
respect to the period covered by such invoice the estimated fixed and variable
costs for such period, any other charges that comprise the monthly charge
determined in accordance with Addendum V hereto, and any other charges provided
for by this Agreement. Within forty-five (45) business days following the end of
each quarter, Provider will provide Recipient with a statement that reconciles
the estimated fixed and variable costs allocated on a monthly basis for such
quarter with the fixed and variable costs actually incurred for such quarter,
and provide a credit for any excess payment, and submit an invoice for any
underpayment.

     Provider will use commercially reasonable efforts to provide Recipient with
an invoice by the third business day of the month following the month in which
the Services were rendered.

     Recipient must notify Provider of any objection within thirty (30) days
after its receipt of the invoice, and must provide reasonable details as to
specific charges to which Recipient objects, and the basis for such objection.

Section 6.2  Payment

     Recipient agrees to pay Provider all costs allocated to it in accordance
with this Agreement and all other charges that Provider is entitled to charge
pursuant to this Agreement by wire transfer to a bank account designated by
Provider electronically within two business days of the time of Recipient's
receipt of an invoice prepared in accordance with Section 6.1 hereof.  Any
payments for overcharges or undercharges required under Section 6.1 or Section
16.1 hereof shall be made within ten (10) days of discovery of such overcharge
or undercharge and shall also be made by wire transfer to a bank account
designated by Recipient or Provider, as the case may be.

     If any portion of an amount due to Provider under this Agreement is subject
to a dispute between the Parties, Recipient shall nonetheless pay and remit to
Provider on the date such amount is due all amounts not disputed in good faith
by Recipient.

                        Article 7  Term and Termination

Section 7.1  Initial Term

     This Agreement shall begin on the Effective Date, and shall expire on the
day before the third annual anniversary of the Effective Date (the "Initial
Term"), unless (i) renewed or extended as provided in Section 7.2, Section 7.3
or Section 7.4 hereof or (ii) terminated earlier in accordance with the terms of
this Agreement.

Section 7.2  Renewal Terms

     This Agreement may be renewed for one renewal term of one (1) year if,
during the Initial Term, Recipient gives written notice of renewal at least 360
days prior to the last day of the

                                       5
<PAGE>

Initial Term.

     If Recipient renews this Agreement in accordance with the foregoing
paragraph, then this Agreement may be renewed for a second renewal term of one
(1) year if Recipient gives written notice of the second renewal at least 360
days prior to the last day of the first Renewal Term (the Initial Term and each
Renewal Term are collectively referred to herein as the "Term").

Section 7.3  Extension of Telecom Carrier Contract Services

     If, during the Term and with the consent of Recipient, Provider enters into
any new Third Party Agreement for telecommunications carrier services, or, after
receiving the prior written consent of Recipient, extends or renews any existing
Third Party Agreement for telecommunications carrier services in order to
provide Telecom Carrier Contract Services to Recipient and Provider, and such
new, extended or renewed Third Party Agreement for telecommunications carrier
services expires after the Term, then this Agreement shall be extended (but only
for Telecom Carrier Contract Services and not for Telecom Support Services or
other Services and not for purposes of the Tandem Exclusive) until any such new,
extended or renewed contract has expired.

Section 7.4  Extension in Connection with Termination Assistance

     If, pursuant to Section 7.8, Recipient requests that Provider provide
Termination Assistance Services, then this Agreement shall be extended (but not
for purposes of the Tandem Exclusive) during the period that Provider provides
such Termination Assistance Services.

Section 7.5  Termination

     (a)  Recipient may terminate this Agreement for the following reasons:

          (i)    For convenience by  giving Provider at least one (1) year prior
     notice designating the termination date and paying the amounts described in
     Addendum VI--Termination Fee (the "Termination Fee"); or

          (ii)   if Provider becomes insolvent or is unable to pay its debts or
     enters into or files (or has filed or commenced against it) a petition,
     arrangement, application, action or other proceeding seeking relief or
     protection under the bankruptcy laws of the United States or any similar
     laws of the United States or any state of the United States, or make a
     general assignment for the benefit of creditors;

          (iii)  Under the circumstances described in the Procedures Manual (as
     defined below) by giving such notice, and paying such fees, if any
     described in the Procedures Manual, and by paying the Termination Fee.

     (b)  Provider may terminate this Agreement if Recipient defaults in the
payment when due of any undisputed amount due to Provider and does not cure such
default within thirty (30) days after receiving notice of the default.  Upon any
such termination, Recipient shall pay Provider all charges and costs accrued and
payable through the date of termination plus the

                                       6
<PAGE>

Termination Fee.

Section 7.6  Rights Upon Termination

     At the expiration or earlier termination of this Agreement for any reason,
however described, the Parties agree as follows:

     (a)  Upon Recipient's request, Provider agrees to transfer to Recipient
that portion of the equipment and hardware used by Provider as of the Effective
Date to provide the Services to Recipient, in accordance with the terms of
Article 8 below;

     (b)  Each Party will provide to the other a source code and object code
license to any derivative works of Shared Software required to be provided under
Section 11.4 below;

     (c)  If Provider is a licensee of any software which is used only for the
purpose of providing Services to Recipient, Recipient may elect to take a
transfer or an assignment of such license, subject to the terms of such license,
and provided that Recipient assumes responsibility for any maintenance or other
payments under such Third Party Agreements that arise or become due and payable
after the effective date of termination or expiration of the Agreement.  In the
event of a transfer or assignment pursuant to this Section 7.6(c), Recipient
shall also pay any transfer fee or similar charge imposed by the applicable
vendor;

     (d)  If Provider is a licensee of any software which is used both for the
purpose of providing Services to Recipient and for Provider's own needs, and
Recipient must obtain its own license if it intends to use such software after
the effective date of termination or expiration of this Agreement  each Party
will be responsible for obtaining their respective licenses, but if any one-time
fee is imposed by a vendor to grant such license (but not any ongoing fees or
royalty payments), such one time fee shall be shared by the parties equally, and

     (e)  Upon Recipient's request, Provider will transfer or assign to
Recipient or its designee, on mutually acceptable terms and conditions, any
Third Party Agreements not otherwise treated in this Article 7.

Section 7.7  Cessation of Performance; Payment

     Upon expiration or termination of this Agreement for any reason, except as
provided in Section 7.8, Provider will cease to have any obligation to perform
the Services hereunder, and Recipient will pay and remit to Provider all amounts
due to Provider for all Services provided and expenses incurred  through the
date of such expiration or termination.

Section 7.8  Termination Assistance Services

     In connection with the expiration or termination of this Agreement for any
reason, Provider will, at the request of Recipient, (i) provide the Tandem
Services for up to six (6) months and (ii) provide the termination assistance
services reasonably requested by recipient  for up to twelve (12) months, in
each case as reasonably needed by Recipient in order to assist Recipient in the
orderly transfer of the Services from Provider to Recipient or to another
services

                                       7
<PAGE>

provider (collectively, the "Termination Assistance Services"); provided,
however, that (i) Recipient shall be obligated to pay all fees and expenses of
Provider incurred in connection with the rendering of said Termination
Assistance Services, and (ii) upon a termination by Provider pursuant to Section
7.5(b), Provider shall not be required to provide Termination Assistance
Services unless Recipient prepays the applicable monthly charges for the entire
duration of the Termination Assistance Services within 30 days of notice of its
intent to terminate.

Section 7.9  Survival of Selected Provisions

     Notwithstanding the expiration or earlier termination of this Agreement for
any reason, however described, the following sections of this Agreement shall
survive any such expiration or termination: Article 1, Section 7.4, Section 7.6,
Section 7.7, Section 7.8, Section 7.9, Article 8, Section 11.2, Section 11.3,
Section 11.4, Article 13, Article 14, Article 15, Section 16.8, Section 16.10,
Section 16.11, Section 16.12, Section 16.13 and Section 16.14.  Upon termination
or expiration of this Agreement, all rights and obligations of the Parties under
this Agreement will immediately cease and terminate (except for the rights and
obligations under those Sections specifically designated to survive in this
Section 7.8).

                   Article 8  Ownership of Certain Equipment

     (a)  During the Term, Provider may purchase one or more items of computer
equipment and related devices to be added to the Tandem System, the Telecom
System and any other systems used to provide the Services (the "Ancillary
Systems") in order to satisfy the capacity requirements of Recipient as
reasonably determined by it pursuant to the capacity planning process described
in Addendum VII - Capacity Planning.  All such equipment and devices (the "Added
Devices") shall be owned by Provider.  Provider will be responsible for
maintaining, supporting and operating the Added Devices subject to payment by
Recipient of the actual costs incurred by Provider determined in accordance with
Addendum V hereto.

     (b)  Recipient will pay Provider a monthly fee for the Added Devices equal
to (i) the sum of the invoice price for each such Added Device plus any
installation costs associated with the integration and implementation of the
Added Device into the Tandem System divided by (ii) the number of months over
which such Added Device is depreciated by Provider for financial accounting
purposes (provided that the depreciation method is in accordance with generally
accepted accounting principles and is approved by Recipient (which approval
shall not be unreasonably withheld)).  Upon the expiration or termination of
this Agreement, Recipient must pay an amount equal to  the sum of the remaining
monthly payments required to be paid by Recipient to Provider for such Added
Devices under this subsection (b), and may acquire possession and ownership of
such Added Devices from Provider upon the payment of one-half of Provider's
reasonable expenses to transfer possession of same to Recipient (including
without limitation, the remaining costs of any Added Devices as required above,
any costs incurred by Provider in connection with the disconnection of the Added
Devices, any cost of reconnecting any portions of the Tandem System, the Telecom
System or any Ancillary System necessitated by the disconnection of the Added
Devices, and all crating and shipping charges).  Any leasehold improvements
required in connection with any Added Devices will be governed by the [Lease
Agreement].

                                       8
<PAGE>

     (c) In addition, upon the expiration or termination of this Agreement,
Recipient may acquire possession and ownership from Provider of that portion of
the Tandem System, the Telecom System and any Ancillary System owned by Provider
and used by Provider as of the Effective Date to provide Services to Recipient,
or that Provider otherwise agrees to transfer to Recipient, upon payment of an
amount equal to one-half of Provider's reasonable expenses to transfer ownership
and possession of same to Recipient (including without limitation any costs
incurred by Provider in connection with disconnection of such equipment and
devices, any cost of reconnecting any portions of the Tandem System, the Telecom
System or any Ancillary System necessitated by the disconnection of such
equipment and devices, and all crating and shipping charges).  Provider
represents, warrants and covenants that any and all computer equipment and
related devices transferred to Recipient pursuant to this Article 8 shall be in
good working condition as of the date of transfer to Recipient.

     If any portion of the Tandem System, the Telecom System or any Ancillary
System that Recipient acquires under this Article 8 is subject to a third party
lien or security interest, Recipient , in addition to any other payment required
by this Section, must assume Provider's obligations under such lien or security
interest if permitted by the terms of the applicable lien or security interest,
and if not permitted, satisfy such lien or security interest.

     (d) Provider and Recipient acknowledge and agree that either party may
purchase equipment and devices for its exclusive use (the "Exclusive Devices")
that will interconnect with the Tandem System, the Telecom System or Ancillary
Systems; provided, however, that the party wishing to interconnect an Exclusive
Device must first demonstrate that the interconnection of such Exclusive Device
to the Tandem System will not materially and adversely affect the integrity,
security, functionality or performance of the Tandem System.  The Party adding
such Exclusive Device will be responsible for maintaining, supporting and
operating it.  The Parties may, however, negotiate a fee pursuant to which
Provider will maintain, support and operate an Exclusive Device of Recipient
during the Term.

                           Article 9  Service Levels
Section 9.1  General

     The Parties have agreed to a procedures manual (the "Procedures Manual")
that governs the performance of the Services by Provider.  Provider agrees that
the performance and delivery of the Services will meet or exceed any agreed upon
service levels to be set forth in the Procedures Manual, and Recipient agrees
that its only remedies for the failure of the performance or delivery of the
Services to meet or exceed any agreed upon service levels set forth in the
Procedures Manual will be the remedies, if any, set forth in the Procedures
Manual.

Section 9.2  Future Service Levels

     If a service level for a particular Service or aspect of the Services is
not set forth in the Procedures Manual, and Recipient requests that one or more
service levels be established for a particular aspect of the Services, then
Provider, with the assistance of Recipient, shall perform an assessment of the
historical service levels as they existed for the twelve (12) month period
before

                                       9
<PAGE>

the Effective Date for such aspect of the Services, and Provider will propose
service levels based on that assessment. When service levels for such aspect of
the Services have been accepted in writing by Recipient and Provider, such
service levels shall be incorporated into the Procedures Manual, and Provider
will thereafter perform in accordance with such new service levels. The Parties
intend that any and all service levels will not be less favorable to Recipient
during the Term than they are at the initiation of the Services pursuant to this
Agreement.

Section 9.3  Review and Remedy

     The Parties will review the extent to which the Services were performed in
accordance with the Procedures Manual as part of each Monthly Review (as that
term is defined below). If the Services have been performed at a level below any
applicable service levels included in the Procedures Manual, each Party may
propose one or more remedies if no specific remedy is set forth in the
Procedures Manual.  These remedies can include modification of the applicable
service levels, equipment changes or changes in operational processes.  If,
after the involvement of the Senior Representatives, the Parties are unable to
agree to remedies, either Party may invoke the provisions of Article 15.
Notwithstanding the foregoing, in the event that the Parties cannot reach
agreement regarding a remedy for a failure to meet applicable service levels
after resort to the dispute resolution procedures set forth in Article 15, then
the Parties may pursue the remedies, if any, available under the Procedures
Manual.

               Article 10  Project Management and Administration

Section 10.1  Senior Representatives; Monthly Reviews

     Provider and Recipient each shall appoint a senior member of management to

Senior Representative shall meet at least one time each calendar month (the
"Monthly Review") to review Provider's performance under this Agreement.

Section 10.2  Account Managers; Weekly Meetings

     Provider and Recipient will each appoint an account manager to serve as
such Party's main contact with the other Party for project and request
submissions, status reporting, disputes and other issues related to this
Agreement (each, an "Account Manager").  The Account Managers shall hold weekly
meetings (the "Weekly Meetings") to discuss performance under this Agreement and
all operational and administrative issues relating thereto.  The Weekly Meeting
will be the formal mechanism for Recipient to submit new Ad Hoc Project requests
and discuss on-going Ad Hoc Projects.

     (a)  Provider will consult with Recipient in each instance prior to

the human resources allocated by Provider as of the Effective Date to the
performance and delivery of the Services, or, with respect to Ad Hoc Projects,
assigned to the performance of an Ad Hoc Project pursuant to Addendum IV hereto.
Provider will use commercially reasonable efforts to maintain continuity of the
persons performing Services under this Agreement.

     (b)  If Recipient reasonably and in good faith determines that it is not in
Recipient's best interests for any Provider or subcontractor employee to be
appointed to perform or to continue performing any of the Services, Recipient
shall give Provider written notice specifying the reason for its position and
requesting that such employee not be appointed or be removed from the Provider
group servicing Recipient and be replaced with another Provider employee.
Promptly after its receipt of such a notice, Provider shall investigate the
matters set forth in the notice, discuss with Recipient the results of the
investigation, and the Parties will use commercially reasonable efforts to
resolve the matter on a mutually acceptable basis.  Since the Provider is
ultimately accountable for delivery of service to Recipient, Provider shall be
the party ultimately responsible for deciding the resolution of such issues.

Section 10.6  Efficient Use of Resources

     Provider shall take commercially reasonable actions to efficiently
administer, manage, operate and use the resources employed by Provider to
provide and perform the Services that are chargeable to Recipient under this

Section 11.1  Third Party Agreements

     (a)  NDC represents and warrants that it has obtained all Required Consents
(as defined below) under the contractual, leasing and licensing arrangements
used by NDC to provide the Tandem Services and the Telecom Contract Carrier
Services (the "Third Party Agreements").  The parties have agreed on a list of
all Third Party Agreements.  NDC will use the services, products and software
licensed or acquired under the Third Party Agreements, together with the Shared
Software (as that term is defined below) and the computer hardware and other
devices owned by it to operate the Tandem System, the Telecom System and the
Ancillary Systems and to provide and deliver the Tandem Services and the Telecom
Contract Carrier Services to Recipient under the terms of this Agreement.

     (b)  The Parties believe that the terms and conditions of the Third Party
Agreements permit Provider to provide the Tandem Services and the Telecom
Contract Carrier Services to

                                       11
<PAGE>

Recipient pursuant to the terms of this Agreement without any increase in any
royalty fee or any other adverse change in the terms and conditions of such
agreements; however, to the extent that Provider determines or has notice of any
claim that any Third Party Agreement restricts Provider from providing any of
such Services, Provider shall promptly negotiate an amendment to such Third
Party Agreement so that it may provide such Services (whether by the grant of a
sublicense or otherwise), and in such event if Provider incurs any increase in
the cost of the royalty fee or other adverse change in the terms and conditions
of an existing Third Party Agreement, or renewal or extension thereof, the
Parties shall share proportionately in the additional cost of such Third Party
Agreement (or the increased royalties or the cost of any other adverse change in
the terms and conditions) that corresponds to Recipient's proportionate use of
such Third Party Agreement. For purposes of this Agreement, Required Consents
means any consents or approvals required to be obtained for the Recipient and
Provider to have access to, and use of, the space, equipment, software and/or
third party services provided under the Third Party Agreements in connection
with the Services.

     Except as provided above, Provider will be responsible for the payment of
all license fees, royalty fees, maintenance fees, acquisition costs or similar
costs incurred in connection with the use of Third Party Software, all of which
will be included as part of the cost allocation process described in Addendum V-
-Allocation of Costs.  Recipient will be responsible for the payment of all
license fees, royalty fees, maintenance fees, acquisition costs or similar costs
of any Third Party Software used by Provider solely to provide Services to
Recipient, none of which will be included as part of the cost allocation process
described in Addendum V--Allocation of Costs.

Section 11.2  Shared Software

     Prior to the Effective Date, Provider had internally developed certain

Section 11.3  Use and Licensing Restrictions on Shared Software

     (a)  Notwithstanding its joint ownership of the Shared Software, Provider
agrees that it may not, during the Term or at any time thereafter, use any

the Services for Recipient in accordance with this Agreement).

     (b)  Notwithstanding its joint ownership of the Shared Software, Recipient
agrees that it may not, during the Term or at any time thereafter, use any
Shared Software to operate or facilitate the operation of any business
substantially similar to the Health Business.

     (c)  The Parties agree that, in the event that any Shared Software is sold
or licensed by either Party during the Term to any third party, all net revenue
received in connection with such

                                       12
<PAGE>

sale or license shall be divided equally between the Parties.

     (d)  In the event that either Party breaches the restrictions set forth in
this Article 11 with respect to Shared Software, the non-breaching Party shall
be entitled to seek injunctive relief and damages for such breach.

Section 11.4  Derivative Works

     (a)  Each Party has the right to develop derivative works of any of the
Shared Software.  The Parties agree that derivative works of Shared Software
developed by a Party shall also be considered to be Shared Software and shall be
subject to all of the restrictions contained in Section 11.3 above, provided
however, in the case of a derivative work of Shared Software that executes
solely on a technology platform other than a Tandem platform, the restrictions
on use and licensing set forth in this Article 11 shall expire ten (10) years
after the effective date of the termination or expiration of this Agreement.

     (b)  During the Term, each Party shall be obligated to furnish to the other
Party any and all derivative works of any Shared Software that execute on a
Tandem platform, but neither Party shall be obligated to furnish to the other
Party any derivative works of any Shared Software that executes solely on a
technology platform other than the Tandem platform.  After the Term, neither
Party shall be obligated to furnish the other Party any derivative works of any
Shared Software.

Section 11.5  Application of Current Technology

     In providing Services hereunder, Provider will continue to utilize the
technology that was used prior to the Effective Date.  Provider may not make
changes to its technology that materially and adversely affect the Services.

     If Recipient consents to any change to the technology used by Provider to
perform the Services, and the Parties determine that such change materially
increases the quality of the Services, any increased development costs, expenses
or fees associated with such technology changes will be shared by Provider and
Recipient based on the (proportionate) use of the Services that were materially
improved in quality.

Section 12.3  Virus Avoidance

     Each Party will take commercially reasonable measures to ensure that no
virus or similar items are coded or introduced into any software used to provide
the Services and the operating environments used to provide the Services.  Both
Parties will continue to perform and maintain at least the virus protection and
correction procedures and processes in place at Provider prior to the Effective
Date.  If a virus is found to have been introduced into any software or
operating environment used to provide the Services, both Parties shall use
commercially reasonable efforts and diligently work to eliminate the effects of
the virus.  However, Provider shall take immediate action to remediate the
virus' proliferation in the Tandem System and the operating environment used to
provide the Services.  The Party causing or permitting a virus to be introduced
into any software or operating environment used to provide the Services shall
bear the costs associated with such efforts and the Losses caused by such a
virus.  If Recipient introduces or permits the introduction of a virus, Provider
shall be relieved of the affected services levels described in the Procedures
Manual to the extent such virus impacts Provider's ability to satisfy such
service levels.

Section 12.4  Disabling Codes

     Each Party agrees that it will not insert or use disabling codes in any
software or equipment used to provide the Services.  The Parties further
covenant that with respect to any disabling code that may be part of any

such disabling code at any time, including upon expiration or termination of
this Agreement for any reason.

Section 12.5  Pass-Through Warranties

other proprietary right of any third party.

Section 12.8  Regulatory Proceedings and Compliance with Laws

     Each Party agrees, at its cost and expense, to obtain all necessary
regulatory approvals applicable to its business, to obtain any necessary permits
for its business, and to comply with all

<PAGE>

laws and regulatory requirements applicable to the performance of its
obligations under this Agreement. If a Party seeking a regulatory approval or a
necessary permit is dependant upon the cooperation of other Party in order to
obtain such approval or permit, the other Party will provide such cooperation as
is reasonably necessary provided that the Party seeking such cooperation shall
reimburse the cooperating Party for all costs incurred in connection therewith.

Recipient's data and other confidential or proprietary information (collectively

After such a review, to the extent such Party does not dispute the conclusions
of the audit, such Party shall pay the other Party the undisputed amounts owed.
The disputed amounts, if any, may be resolved pursuant to Article 15.

Section 16.2  No Audit Rights for Telecommunication

     Since Provider is not representing to Recipient that the lowest possible
telecommunications rates or costs will be provided under this Agreement,
Recipient will not have the right to engage a third party to audit the

and carrier services.  Recipient may, however, itself examine and review the
rates specified in the Third Party Agreements for telecomunications carrier
services in connection with the exercise of its audit rights under Section 16.1

Recipient with competitive rates to encourage Recipient to continue to partner

     Recipient, at its expense, shall secure Provider's right to use Recipient's
third party interfaces such as the Visa, MasterCard, Discover, and American

these third parties and paying all expenses related to the

                                       19

(ii) Provider remains primarily liable and obligated to Recipient for the timely
and proper performance of all of its obligations hereunder and for the proper
and timely performance and actions of any person or entity to which it delegates
or subcontracts any such obligation.

Section 16.5  Assignment

     Except as provided in this Section 16.5, neither Party may assign this
Agreement, in whole or in part, without the prior written consent and approval
of the other Party hereto, which consent shall not be unreasonably withheld
(provided however, in the case of any assignment by Provider, the Parties agree
that the only basis on which Recipient may withhold such consent is if the
assignee in not competent to provide the Services), except that either Party
may, in connection with the sale of all or substantially all of its assets, any
merger, consolidation, reorganization, or other business combination to which a
Party is a party, assign its obligations and responsibilities hereunder to the
purchaser in the case of a sale of assets, or the surviving entity in the case
of a merger, consolidation or business combination, without the approval of the
other Party. An assignment will not relieve a Party of any obligations under
this Agreement. Any purported transfer, assignment or delegation that does not
comply with the terms of this Section 16.5 shall be null and void and of no
force or effect.  Notwithstanding the foregoing, neither Party shall have the
right to assign this Agreement and the obligations hereunder to any successor of
such Party by way of merger, consolidation, reorganization or the acquisition of
substantially all of the business and assets of the assigning Party relating to
the Agreement if such successor's principal business is the business of the
other Party (i.e., the Health Business or the eCommerce Business).

it to provide or use, as the case may be, the Services.

Section 16.7  Relationship of the Parties

contractors.  No partnership, joint venture, or other formal business
relationship is hereby created between the Parties hereto. Neither Party shall
make any warranties or representations, or assume or create any obligations, on
the other Party's behalf except as may be expressly permitted hereunder or in
writing by such other Party. Each Party shall be solely responsible for the
actions of all their respective employees, agents and representatives.

Expiration / Extension of Current Telecom Carrier Contracts

     If any Third Party Agreements for telecommunications carrier services
terminate prior to the expiration or termination of this Agreement, Provider

use commercially reasonable efforts to obtain the best possible
telecommunication prices, and will keep Recipient advised as to the pricing that

                         Addendum IV--Ad Hoc Services

General

     Provider will use commercially reasonable efforts to provide to Recipient
such other specific network and systems related services or projects as
Recipient may from time to time reasonably request.

Project Requests; Project Management.

     Recipient shall submit all project requests to Provider using a Provider
specified format. Not later than ten (10) calendar days after a project request
is submitted by Recipient, Provider shall respond in writing either (i) that
Provider is able to perform the project, together with the estimated timeframe
and estimated cost of the project, (ii) that Provider is unable to evaluate its
ability or to perform the project, or to provide an estimated timeframe and
estimate cost for completion of the project, because the project request lacked
needed specificity, information or other omissions, or (iii) in the event that
Provider determines that the requested project will jeopardize overall
reliability, response time, or other material aspects of the Tandem System or
the Telecom System, that Provider will not perform the project. If Provider
informs Recipient that Provider will not perform the project for the reasons set
forth in subsection (iii) of this paragraph, the Provider and Recipient Senior
Representatives will discuss the issues raised by the project request and the
response, in good faith, to see if the Parties can mutually agree to a mutually
satisfactory solution.

     The status of all Ad Hoc Services projects will be reported at the Weekly
Meetings.  The status will include a listing of all projects in process and
submitted, the completion status, and the amount of resources allocated.

     The Provider will allocate one half full-time individual to project review
and costing and include the cost of such in the annual cost allocation. If
Recipient wishes additional manpower devoted to this activity, additional
resource will be added at Recipient's expense.

Resource Commitment

     In conjunction with the projections for Services for each fiscal year, a
certain amount of Ad Hoc Services will be estimated and costed and included in
the overall annual cost to the Recipient.  Once the estimated Ad Hoc Services
have been established, Provider will specify the number of human resources to be
made available to Recipient in terms of man-hours and/or specific personnel for
Ad Hoc Services.  Status reports prepared by Provider pursuant to this Addendum
IV shall summarize the remaining man hours available to Recipient for project
management purposes and describe Recipient's use of available man hours during
the period covered by such report.  All Ad Hoc Services are intended to be
performed by this committed level of resources.  If this resource level is
insufficient to perform the requested Ad Hoc projects, the Recipient will have
the option of requesting adding resources at extra cost.  The costs for
underutilized Ad Hoc resources will not be refunded.  The resources available
for project work will be shared with those resources required for technology
support as is the current practice.

                                       1
<PAGE>

This means that any promised delivery dates will be subject to modification if
support or operations issues arise. Recipient will be promptly informed if the
latter situation occurs. Provider will use commercially reasonable efforts to
increase the resource level on any project if Recipient requests and Recipient
is agrees to fund all incremental costs thereof. The Provider, however, does not
guarantee the ability to increase resource levels due to the specialized nature
of certain skill sets.

                        Addendum V--Allocation of Costs

Cost of Services
----------------

     (a)  Determination of certain costs

     Services will be provided by Provider to Recipient hereunder at costs and
charges based and determined as follows:

     1)   In the case of technology and services shared by Provider and
Recipient, an allocated percentage of Provider's overall cost for shared
technology and services representing Recipient's allocable and proportionate
share of the aggregate costs of such shared technology and services;

     2)   In the case of technology and services exclusively provided to
Recipient, Provider's direct cost to provide Recipient said exclusive technology
or services; and

     3)   In the case of additional requested services, Provider's direct cost
to provide Recipient said additional requested services, including operations,
procurement, engineering and administrative services provided by Provider to
Recipient in connection therewith, which shall be charged to and borne by
Recipient at Provider's actual manpower costs (salary, burden and all other
costs directly associated with such manpower, such as office space, supplies and
similar expenses) directly applicable to the provision of services provided.

     (b)  Fiscal Year basis, etc.

     Costs for Services as provided above are to be quoted by Provider to
Recipient on a fiscal year basis based on a specific set of base services
described in Addendum I--Telecom Services, Addendum II--Tandem Services,
Addendum III--Transition Services and Addendum IV--Ad Hoc Services.  The costing
methodology for the base Telecom Services and Tandem Services is described in
Costing Methodologies, Costing Methodologies for Telecom Services and Costing
Methodologies for Tandem Services.  The costs for Services described in Addendum
III--Transition Services, and Addendum IV--Ad Hoc Services will be billed at the
allocable costs of the cost centers, individuals or other resources providing
such Services, including costs for operations, procurement, engineering and
administrative services provided by Provider to Recipient in connection
therewith, which shall be charged to and borne by Recipient at Provider's actual
manpower costs (salary, burden and all other costs directly associated with such
manpower, such as office space, supplies and similar expenses) directly
applicable to the provision of services provided.  The costs incurred in
connection with Addendum VII--Capacity Planning are included in the costs of
other Services.

     (c)  Cost adjustments

that could cause cost adjustments would include:

          1)   Unforecasted capacity increases required by Recipient

          2)   Recipient requested increases or decreases in support levels

          3)   New technology projects requested by Recipient

          4)   Facility upgrades required by new Recipient projects

          5)   Telecom rate changes

          6)   Price changes by suppliers or vendors

     (d)       Notice of changes

     Provider will provide 30 days prior written notice to Recipient of any
material costing change known to it in advance.

     (e)       Other Charges

     In addition to the charges and fees for services rendered as provided
above, Recipient will also be responsible and charged hereunder for the
following items:

          1)   All unbudgeted travel and other out-of-pocket expenses incurred
               by Provider in connection with Provider's performance of its
               obligations under this Agreement,

          2)   All taxes, assessments, duties, permits, fees and other charges
               of any kind imposed on this Agreement, the Services or use of
               Provider Systems or Provider Licensed Software (other than any
               taxes on, or based on, the income of Provider); and

          3)   All costs incurred by Provider in connection with unusual reruns
               necessitated by incorrect or incomplete data or erroneous
               instructions supplied to Provider by Recipient or for corrections
               of programming, operator or other processing errors caused by
               Recipient.

     Costing Methodologies

     The methodology is keyed to the nature of the technology or service area
and the intent is that any necessary allocation be equitable and proportional to
relative usage in nature. The capacity costs required to be paid by Recipient
will be based on the actual costs to provider for the capacity dedicated to
Recipient hereunder.

Costing Methodologies for Telecom Services
------------------------------------------

     (a)  Telecom Carrier Charges (explicit or allocated)

     Minutes, line charges, fees, maintenance, equipment, and related telecom
carrier charges will be charged to Recipient based on either explicit usage
(i.e. such charges are for services provided exclusively to Recipient and
identified as such in the carrier billing) or on an allocated cost basis in
those cases where the carrier services is shared by the Parties under an
arrangement with consolidated billing.  The allocation will be based on
proportionate usage as reasonably determined by Provider.  The costs invoiced to
Recipient will be on a pass-through basis with a prorated share of overhead
costs added.

     (b)  Telecom staff (allocated)

     Network operations, engineering, provisioning, administration, and
installation costs will be allocated based on proportionate usage as reasonably
determined by Provider.

Costing Methodologies for Tandem Services
-----------------------------------------

     Recipient will be charged a percentage of the Tandem depreciation,
hardware/software maintenance costs, license fees, operations and technical
support manpower costs, supplies, data center facilities costs, and other
similar costs based on their portion of usage of the Tandem System.  This
percentage will be calculated one year in advance based on the Projected Volumes
shown in the 12-month rolling forecast.  This percentage is to be considered a
minimum due to fixed costs incurred for the next 12 months.  If usage increases
beyond the initial percentage, the percentage of costs will be adjusted upwards
on a monthly basis.  The percentage of usage is calculated by dividing the
overall capacity of the Tandem System at the beginning of the fiscal year by the
Recipient transaction count.  Any excess capacity in the Tandem System will be
proportionally allocated between the Recipient and the Provider.  If either
Party transitions off the Tandem System at a rate substantially faster than the
other Party, it is agreed that such other Party will not be allocated costs for
any excess capacity in excess of 20%.  Increased transactions of the Recipient
that fit within the excess capacity allocated to Recipient will not incur
additional cost.

                         Addendum VI--Termination Fee

     The Termination Fee shall equal the sum of the following:

     .    Balance of any software license or maintenance agreements allocable to
Recipient through the end of the Initial Term, provided however that Recipient
shall be entitled to receive the benefit of any early termination provisions
included in those agreements and Provider shall attempt to mitigate against the
assessment of any penalties of fees against Recipient

     .    Book value or remaining lease balance of any facility installations
installed solely to accommodate Recipient processing or forecasted volume, to
the extent that payment for such facility installations is not otherwise
provided for by the [Lease Agreement].

     .    Telecom or other rate increases (including any loss of rate
reductions) due to Provider not being able to satisfy contract minimums after
the effective date of such termination.

     .    One half of any other costs reasonably incurred by Provider that are
directly related to splitting or transitioning hardware or software to Global.

                        Addendum VII--Capacity Planning

12-Month Rolling Forecasts

     To facilitate capacity planning, Recipient will provide to Provider a 12-
month rolling  forecast of expected transaction volumes for the Tandem System
(including hardware) and Telecom System capacity planning purposes in a format
to be provided by Provider. Said 12-month forecast shall be provided by
Recipient each month by the first day of each calendar month and shall provide a
firm and fixed forecast commitment for the ensuing twelve calendar months.
These capacity forecasts will be used by Provider as the basis for acquisition
of Tandem hardware, TCP/IP network, and telecommunications capacity and for the
charges for the Services in accordance with Addendum V. Provider and Recipient
will meet at least monthly to review capacity requirements as well as actuals
against forecasted plan.

Additional Capacity Requirements

     If Provider reasonably determines that additional equipment is required for
the sole purpose of satisfying the Recipient capacity requirements as reflected
in capacity forecasts provided by Recipient to Provider hereunder, Provider
shall promptly notify Recipient in writing and Recipient shall have up to 15
calendar days to either consent to such purchase by Provider or to give notice
that it disputes the need for such purchase, in which case the dispute will be
resolved pursuant to Article 15.
