Item 1.   Not Applicable

Item 2.  Acquisition or Disposition of Assets

On April 1, 1996, National Data Corporation and certain of its subsidiaries
(collectively, the "Registrant") organized a new Georgia limited liability
company, Global Payment Systems LLC, ("GPS"), to which it transferred its
Payment Services business unit, its Information Systems and Services business
unit and certain back office support functions from the Registrant's Payment
Systems business unit.  In addition, the Registrant contributed to GPS
$60,000,000 and loaned $50,000,000. The total cash from the Registrant,
$110,000,000, transferred to GPS was paid by using cash on-hand of
approximately $104,000,000 with the remaining $6,000,000 borrowed under an
existing acquisition line of credit.  The Registrant also agreed to lend
working capital to GPS not to exceed $15,000,000.  GPS then acquired a business
unit from MasterCard International Incorporated ("MasterCard").  The business
unit acquired, the MasterCard Automated Point-of-Sale Program ("MAPP"),
consisted of tangible personal property, leased personal and real property,
customer contracts, assembled work force and the goodwill of the business.

The establishment of GPS and the acquisition of the MAPP business unit was
consummated pursuant to an Asset Purchase and Contribution Agreement by and
among MasterCard, the Registrant and GPS dated as of February 22, 1996, as
amended (the "Contribution Agreement").  Pursuant to the Contribution Agreement
the purchase price paid for the assets of the MAPP business unit by GPS was
$110,000,000 in cash plus the granting of a 7.5% membership interest in GPS to
MasterCard.

Pursuant to the Contribution Agreement, MasterCard and the Registrant entered
into an Operating Agreement dated as of March 31, 1996, which sets forth
certain rights and obligations of the parties thereto regarding GPS, including
rights regarding the earnings of GPS.  Subject to earlier termination upon
conversion of GPS into a corporation at the Registrant's election, the
Registrant will be entitled to receive a special allocation of 99% of the
earnings from GPS through May 31, 1998,  97% of the earnings from GPS from June
1, 1998 through May 31, 1999, and 95% of the earnings from GPS from June 1,
1999 through May 31, 2000.  Thereafter, 92.5% of the earnings from GPS will be
distributed to the Registrant, with the balance of the 7.5% of the earnings
being distributed to MasterCard.  Upon the conversion of GPS into a
corporation, the earnings will be distributed in accordance with MasterCard's
and the Registrant's respective ownership interests.

In the Contribution Agreement, the parties entered into various indemnification
agreements and agreements relating to the employment of the former MAPP
employees.  Pursuant to the Contribution Agreement, the Registrant and GPS,
and MasterCard and GPS entered into service agreements and subleases.
Additionally, GPS and Mastercard entered into a registration rights agreement
providing for, among other things, certain "demand" and "piggy-back"
registration rights upon any future public offering of securities of GPS.
These agreements also provide that MasterCard shall be entitled to one 

<PAGE>   3

GPS board seat until the earlier of (1) MasterCard's disposition of more than
50% of its initial membership interest in GPS or (2) GPS's completion of an
initial public offering.

The purchase price for the MAPP business was $128,750,000, which consists of
the $110,000,000 in cash and the 7.5% minority interest with an estimated value
of $18,750,000.

The acquisition of MAPP will be accounted for using the purchase method of
accounting.  The net value of the tangible assets acquired was approximately
$8,391,000 creating an excess cost over tangible assets of $120,359,000.  The
Registrant is in the process of receiving an independent appraisal of the value
of the assets acquired.  It is estimated that the intangible assets will have
useful lives as follows:


<TABLE>
                         <S>                   <C>
                         Customer Contracts    25 years
                         Assembled Work Force  10 years
                         Trade Name            40 years
                         Goodwill              40 years
</TABLE>


MAPP used the tangible fixed assets, principally mainframe computer hardware
and communications equipment, to provide transaction processing services to
financial institutions, including the authorization and capture of transactions
involving credit cards.  The Registrant intends to continue the same or similar
use of all assets acquired.

The foregoing is qualified in its entirety by reference to the Contribution
Agreement, as amended, and the exhibits thereto filed as Exhibits 2.1 and 2.2 
hereto and incorporated herein by reference.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION
    MasterCard Automated Point-of-Sale Program ("MAPP") is a business unit
    established and operated by MasterCard International Incorporated
    ("MasterCard") that provides transaction processing services to acquiring
    members, including the authorization and capture of transactions involving
    credit, debit and similar cards, through utilization of an electronic
    telecommunications and computer network.  MAPP is not a distinct legal
    entity.

    On February 22, 1996, MasterCard entered into an agreement with National
    Data Corporation ("NDC") to form a new payment processing company called
    Global Payment Systems ("GPS") that will consist of MAPP and NDC's payment
    services business, point-of-sale and back-office services.  MasterCard will
    contribute to GPS certain assets of MAPP and GPS will assume certain
    liabilities of MAPP as of April 1, 1996.  In return, MasterCard will
    receive $110 million in cash and a 7.5% equity ownership in GPS.  The
    transaction is expected to close in the second quarter of 1996.

    The Securities and Exchange Commission, in Staff Accounting Bulletin No. 55
    ("SAB 55"), requires that historical financial statements of a subsidiary,
    division, or lesser business component of another entity include certain
    expenses incurred by the parent on its behalf.  These expenses generally
    include, but are not limited to, officer and employee salaries, rent,
    depreciation, accounting and legal services, other selling, general and
    administrative expenses, and other such expenses.  These financial
    statements, as described in Note 2, include the estimated costs of such
    expenses and services.

    These financial statements include the historical financial position,
    results of operations and cash flows of MAPP previously included in the
    MasterCard consolidated financial statements.  These financial statements
    have been prepared by MasterCard management in conformity with generally
    accepted accounting principles and include such estimates and adjustments
    as considered necessary to present fairly the financial position of MAPP at
    December 31, 1995 and 1994 and the results of its operations and its cash
    flows for each of the three years in the period ended December 31, 1995.

    BASIS OF PRESENTATION
    MAPP follows generally accepted accounting principles.  Assets and
    liabilities are carried principally at historical cost and the accrual
    method of accounting is followed.  Preparation of financial statements in
    conformity with generally accepted accounting principles requires
    management to make estimates and assumptions that affect the reported
    amounts of assets and liabilities and disclosure of contingent assets and
    liabilities at the date of the financial statements and the reported
    amounts of revenue and expenses during the reporting period.  Actual
    results could differ from those estimates.

    REVENUE RECOGNITION
    Revenue represents fees for services provided to members of MasterCard and
    is recognized as services are provided.

    FIXED ASSETS
    Fixed assets are stated at cost.  Depreciation on computer equipment and
    furniture and fixtures is computed under the straight-line method over the
    estimated useful lives of the related assets, which do not exceed five
    years.  The costs of purchased and internally developed software are
    capitalized and amortized on a straight-line basis over their estimated
    useful lives, which do not exceed five years.

    INCOME TAXES
    MasterCard utilizes the asset and liability method of accounting for income
    taxes.  Deferred tax assets and liabilities are recognized for the future
    tax consequences attributable to differences between the financial
    statement carrying amounts of existing assets and liabilities and their
    respective tax bases.  Deferred tax assets and liabilities are measured
    using enacted tax rates expected to apply to taxable income in the years in
    which those temporary differences are expected to be recovered or settled.
    The effect on deferred tax assets and liabilities of a change in tax rates
    is recognized in income in the period that includes the enactment date.

    Historically, the results of MAPP's operations have been included in the
    consolidated U.S. federal income tax return of MasterCard.  The income tax
    expense and other tax related information in these financial statements is
    presented as if MAPP had not been eligible to be included in the
    consolidated tax returns of MasterCard (i.e., MAPP on a stand-alone basis).
    The recognition and measurement of income tax expense and deferred income
    taxes requires certain assumptions, allocations, and significant estimates
    which management believes are reasonable to measure the tax consequences as
    if MAPP were a stand-alone taxpayer.

2.  RELATED PARTY TRANSACTIONS

    MAPP processes transactions with MasterCard's members in the normal course
    of business.  In addition, MAPP enters into transactions with MasterCard
    which are discussed in further detail below:

    CASH AND CASH EQUIVALENTS
    MAPP accounts receivable are collected by MasterCard and cash is invested
    centrally by MasterCard.  Additionally, disbursements are funded centrally.
    As a result, MAPP maintains a zero cash balance on its books and receives
    charges and credits against Parent Company Investment for cash collected
    and used.

    ALLOCATED CORPORATE EXPENSES
    MasterCard allocates a certain portion of its corporate expenses to its
    business units.  These costs include human resources, legal, accounting,
    audit, occupancy, data processing and network operations, but do not
    include allocations of MasterCard executive management costs.  Allocations
    of rentals for office space of $1,395, $997 and $935 for the years ended
    December 31, 1995, 1994 and 1993,

    respectively, are included in occupancy expense.  All other allocated
    corporate expenses of $1,794, $1,226 and $1,427 for the years ended
    December 31, 1995, 1994 and 1993, respectively, are presented as a separate
    line item in the Statement of Income.

    Corporate expenses are allocated based on a variety of factors (e.g.,
    square footage, head count, transaction volumes, etc.) which management
    believes to be reasonable.  These costs could have been different had MAPP
    operated on its own during the periods presented.

    MasterCard does not charge its business units for the carrying costs
    related to its investment in such units (parent company investment).
    Therefore, MAPP's results of operations for each of the periods presented
    do not include any allocated interest charges from MasterCard.

3.  FIXED ASSETS

    Fixed assets are comprised of the following at December 31:

    Depreciation expense aggregated $3,416, $2,929 and $2,708 for the years
    ended December 31, 1995, 1994 and 1993, respectively.  Amortization expense
    related to capitalized software aggregated $559, $504 and $0 for the years
    ended December 31, 1995, 1994 and 1993, respectively.

4.  EMPLOYEE BENEFIT PLANS

    MAPP participates in the MasterCard noncontributory defined benefit pension
    plan.  For the years ended December 31, 1995, 1994 and 1993, $358, $366 and
    $250, respectively, of pension expense was allocated to MAPP.  MAPP also
    participates in MasterCard's defined benefit/defined contribution plan for
    providing postretirement medical and life insurance benefits.  For the
    years ended December 31, 1995, 1994 and 1993, $227, $305 and $243,
    respectively, of postretirement expense was allocated to MAPP.  As a
    multiemployer plan, separate information regarding the components of cost,
    plan assets, accumulated and projected benefit obligations, and related
    liabilities or prepaid asset amounts for these plans are not available for
    MAPP.

</TABLE>

    MAPP's deferred tax liabilities of $273 and $462 at December 31, 1995 and
    1994, respectively, result primarily from differences in the amounts
    recorded and the amounts recognized for income tax purposes for fixed
    assets and employee benefits.  The provision for income taxes varies from
    the amounts computed by applying the applicable U.S. federal income tax
    rate to income before taxes primarily as a result of state income taxes.

6.  COMMITMENTS AND CONTINGENCIES

    Future minimum lease payments under noncancellable operating leases with
    initial or remaining terms in excess of one year at December 31, 1995 are

7.  ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS

    Due to their short-term nature, the carrying amount of accounts receivable
    and accounts payable reported on the balance sheet approximates estimated
    fair value.

8.  PARENT COMPANY INVESTMENT

    Because MAPP is an operating unit and not a distinct legal entity (see Note
    1) there are no customary equity and capital accounts recorded on the
    balance sheet.  Instead, parent company investment is maintained by MAPP
    and MasterCard to account for interunit transactions as described in Note
    2.  Parent company investment consists of net income, advances for capital
    expenditures and other transactions as follows:

PRO FORMA FINANCIAL INFORMATION (UNAUDITED)

The following pro forma financial information has been prepared as if the
transaction reported had taken place on February 29, 1996 for the pro forma
condensed combined balance sheet and June 1, 1994 for the pro forma condensed
combined income statements.  The pro forma results presented are unaudited and
reflect estimates for differences in year end.

This acquisition has been accounted for using the purchase method.  Goodwill
and intangibles resulting from the acquisition will be amortized over an
approximate weighted average period of 38 years.  The purchase price
allocations are estimated at this time pending completion of an appraisal by a
third party appraisal firm.  Any adjustments to the purchase price are not
expected to be material to the pro forma financial information taken as a
whole.

The pro forma financial information is presented for information purposes only
and is not necessarily indicative of the operating results that would have
occurred had the acquisition taken place on the dates indicated, nor are they
necessarily indicative of the results of future operations.  Historical income
statements of the acquired company have been adjusted to reflect differing
fiscal years.  Non-recurring items were excluded from the pro forma
presentation.  The pro forma financial information should be read in
conjunction with the accompanying notes.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1.  Basis of presentation

Certain reclassifications have been made to National Data Corporation's
historical condensed consolidated income statement for the year ended May 31,
1995 used in the pro forma presentation to conform to fiscal 1996 presentation.


Note 2. Narrative description of pro forma adjustments.

a. Cash on hand on June 1, 1994 was approximately $38,000,000.  It is assumed
   that had the transaction been completed on this date, the secondary equity
   offering completed in fiscal 1996 would have already occurred.  This offering
   generated approximately $63,000,000 in cash.


<TABLE>
                 <S>                              <C>
                 Cash on hand at 6/1/94           $ 38,000,000
                 Secondary equity offering          63,000,000
                 Funds borrowed                      9,000,000
                                                  ------------
                    Total Purchase Price          $110,000,000
                                                  ============
</TABLE>

b. Intangibles and goodwill in the amount of $120,359,000 are calculated as
   follows:


<TABLE>
                 <S>                              <C>
                 Purchase price                   $110,000,000
                 Less: Tangible fixed assets        (8,391,000)
                 Minority Interest (7.5%)           18,750,000
                                                  ------------
                                                  $120,359,000
                                                  ============
</TABLE>

     An approximate weighted average of 38 years is assumed for amortization
purposes. It is estimated that the intangible assets will have useful lives as
follows:


<TABLE>
                 <S>                              <C>
                 Customer Contracts               25 years
                 Assembled Work Force             10 years
                 Trade Name                       40 years
                 Goodwill                         40 years

</TABLE>

 Amortization expense for the periods presented is calculated as follows:

      Fiscal Year Ended May 31, 1995       $3,146,000
      Nine Months Ended February 29, 1996   2,360,000



<PAGE>   21



c. Interest income is reduced by the following amounts to reflect the amount of
   interest that would have been forfeited had the transaction occurred on June 
   1, 1994. The average interest rate earned on investments was approximately 
   5% in all periods presented.


<TABLE>
                <S>                                  <C>
                Fiscal Year Ended May 31, 1995       $1,289,000
                Nine Months Ended February 29, 1996   3,406,000
</TABLE>


d. Interest expense is increased by the estimated amount of interest that would
   have been incurred if $9,000,000 was borrowed on June 1, 1994 and continued 
   to remain outstanding through February 29, 1996.   The interest calculation 
   is estimated based on the Registrant's current LIBOR borrowing rate of  
   5.42%.


<TABLE>
                 <S>                                  <C>
                 Fiscal Year Ended May 31, 1995       $488,000
                 Nine Months Ended February 29, 1996   366,000
</TABLE>


e. Minority interest (per the terms of the agreement) for the first two years
   is calculated as 1% of operating income (adjusted for amortization of 
   purchase price), before income taxes.


<TABLE>
                  <S>                                  <C>
                  Fiscal Year Ended May 31, 1995       $24,000
                  Nine Months Ended February 29, 1996   41,000
</TABLE>


f. Income tax rates are adjusted to reflect the reduction of interest income
   which was largely comprised of tax exempt or partially tax exempt amounts.
   Income tax rates were adjusted to the following amounts:


<TABLE>
                   <S>                                  <C>
                   Fiscal Year Ended May 31, 1995       36.9%
                   Nine Months Ended February 29, 1996  36.4%
</TABLE>



g. Earnings per share is presented using the fully diluted number of shares
   outstanding.  In fiscal 1995, it is assumed that the secondary equity 
   offering would have been completed by June 1, 1994 and the number of 
   outstanding shares would have increased by approximately 3,163,000.


h. Stockholder's equity adjustments represent the elimination of the book
   equity of the acquired company, which in this presentation is the value of 
   the tangible fixed assets.

<PAGE>   26

the Parent Contributed Assets and the assumption of the Assumed Liabilities 
and the Newco Assumed Liabilities will be effective as of 11:59 P.M. local 
time on March 31, 1996 (the "Effective Time").

     5.2 Certain Consents.

         (a) If, on the Closing Date, (i) Seller has not obtained any
authorization, approval or consent (a "Consent") required to transfer, assign
or novate (a "Transfer") any of Seller's right, title or interest in or to any
of the Acquired Assets after having used commercially reasonable efforts to
obtain such Consent or an attempted Transfer of any of the Acquired Assets
would be ineffective or the failure to have such Consent would adversely affect
Seller's ability to convey any such Acquired Asset, (ii) the conditions
precedent to the Closing set forth in Article 10 nevertheless have been
satisfied, and (iii) the failure to Transfer such asset, either individually or
in the aggregate, is not reasonably likely to have a material adverse effect on
Seller's Indirect Merchant Network Business or the result of its operations as
conducted by Newco, then such Acquired Assets shall constitute "Deferred
Acquired Assets" and shall not be transferred to Newco at the Closing.  After
the Closing, (a) Seller will (I) continue to use commercially reasonable
efforts to obtain the Consent and/or to remove any other impediments to the
Transfer of each Deferred Acquired Asset and will Transfer each Deferred
Acquired Asset to Newco within five (5) business days after the receipt of such
Consent and/or removal of such impediment and (II) until the Transfer with
respect to any Deferred Acquired Asset is accomplished, cooperate with Newco in
any lawful arrangement that is not unduly economically burdensome (including
performance by Seller as agent) to provide that Newco shall receive the
benefits of such Deferred Acquired Asset to the same extent as if it were
transferred to Newco at Closing, (III) until the Transfer with respect to any
Deferred Acquired Asset is accomplished, enforce, at the request and for the
account of Newco, any of Seller's rights thereto or interests therein against
any other parties thereto (including the right to terminate any such Deferred
Acquired Asset in accordance with its terms, provided that Newco pays any
cancellation or other fee due upon such termination) and (b) if and only to the
extent that Newco receives the benefits of a Deferred Acquired Asset, Newco
shall perform the obligations of Seller arising with respect to such Deferred
Acquired Asset to the extent that, by reason of consummation of the
transactions contemplated by this Agreement, Newco has control over the
resources necessary to perform such obligations or reimburse Seller for the
reasonable cost of such performance.  To the extent Newco performs the
obligations of Seller with respect to any Deferred Acquired Asset, any account
receivable created on account of such performance shall be deemed when created
to be an Acquired Asset conveyed hereunder.  Newco will act with reasonable
diligence and use commercially reasonable efforts to assist, and cooperate
with, Seller in obtaining such Consents and removing any such impediments to
the transfer of the Deferred Acquired Assets.

         (b) If, on the Closing Date, (i) Parent has not obtained any Consent
required to Transfer any of Parent's right, title or interest in or to any of
the Parent 


                                   - 16 -
<PAGE>   27



Contributed Assets after having used commercially reasonable efforts to obtain 
such Consent or an attempted Transfer of any of the Parent Contributed Assets 
would be ineffective or the failure to have such Consent would adversely 
affect Parent's ability to convey any such Parent Contributed Asset, (ii) the 
conditions precedent to the Closing set forth in Article 11 nevertheless have 
been satisfied, and (iii) the failure to Transfer such asset, either 
individually or in the aggregate, is not reasonably likely to have a material 
adverse effect on Parent's Indirect Merchant Network Business or the result of 
its operations as conducted by Newco, then such Parent Contributed Assets 
shall constitute "Deferred Contributed Assets" and shall not be transferred to 
Newco at the Closing.  After the Closing, (a) Parent will (I) continue to use 
commercially reasonable efforts to obtain the Consent and/or to remove any 
other impediments to the Transfer of each Deferred Contributed Asset and will 
Transfer each Deferred Contributed Asset to Newco within five (5) business 
days after the receipt of such Consent and/or removal of such impediment and 
(II) until the Transfer with respect to any Deferred Contributed Asset is 
accomplished, cooperate with Newco in any lawful arrangement that is not unduly
economically burdensome (including performance by Parent as agent) to provide
that the Newco shall receive the benefits of such Deferred Contributed Asset to
the same extent as if it were transferred to Newco at Closing, (III) until the
Transfer with respect to any Deferred Contributed Asset is accomplished,
enforce, at the request and for the account of the Newco, any of Parent's
rights thereto or interests therein against any other parties thereto
(including the right to terminate any such Deferred Contributed Asset in
accordance with its terms, provided that Newco pays any cancellation or other
fee due upon such termination) and (b) if and only to the extent that Newco
receives the benefits of a Deferred Contributed Asset, Newco shall perform the
obligations of Parent arising with respect to such Deferred Contributed Asset
to the extent that, by reason of consummation of the transactions contemplated
by this Agreement, Newco has control over the resources necessary to perform
such obligations or reimburse Parent for the reasonable cost of such
performance.  To the extent Newco performs the obligations of Parent with
respect to any Deferred Contributed Asset, any account receivable created on
account of such performance shall be deemed when created to be an Parent
Contributed Asset conveyed hereunder.  Newco will act with reasonable diligence
and use commercially reasonable efforts to assist, and cooperate with, Parent
in obtaining such Consents and removing any such impediments to the transfer of
the Deferred Contributed Assets.

     5.3 Further Assurances.

         (a) Seller from time to time after the Closing Date, at Newco's
request, will execute, acknowledge, and deliver to Newco such other instruments
of conveyance and transfer and will take such other actions and execute and
deliver such other documents, certifications, and further assurances as Newco
may reasonably require in order to vest more effectively in Newco, or to put
Newco more fully in possession of, any of the Acquired Assets, or to better
enable Newco to complete, perform, or discharge any of the Assumed Liabilities.
Further, if either party discovers that any Contract or other asset was omitted
from the Seller Disclosure Memorandum such that it did not become an Acquired
Asset, then such party shall give notice of such fact to the other; and, if
Newco 

                                   - 17 -
<PAGE>   28


desires to acquire the same, Seller shall assign and convey it to Newco.  To 
the extent that Consent is required to Transfer any such Contract, then such 
Contract shall be a Deferred Acquired Asset, and the provisions of Section 
5.2 shall govern such Contract.  Each of the Parties hereto will cooperate 
with the other and execute and deliver to the other parties hereto such other 
instruments and documents and take such other actions as may be reasonably 
requested from time to time by any other party hereto as necessary to carry 
out, evidence, and confirm the intended purposes of this Agreement.

         (b) Parent from time to time after the Closing Date, at Newco's
request, will execute, acknowledge, and deliver to Newco such other instruments
of conveyance and transfer and will take such other actions and execute and
deliver such other documents, certifications, and further assurances as Newco
may reasonably require in order to vest more effectively in Newco, or to put
Newco more fully in possession of, any of the Parent Contributed Assets, or to
better enable Newco to complete, perform, or discharge any of the Newco Assumed
Liabilities.  Further, if either party discovers that any Parent Contract or
other asset was omitted from the Parent Disclosure Memorandum such that it did
not become an Parent Contributed Asset, then such party shall give notice of
such fact to the other; and, if Newco desires to acquire the same, Parent shall
assign and convey it to Newco. To the extent that Consent is required to
Transfer any such Parent Contract, then such Parent Contract shall be a
Deferred Acquired Asset, and the provisions of Section 5.2 shall govern such
Parent Contract.  Each of the Parties hereto will cooperate with the other and
execute and deliver to the other parties hereto such other instruments and
documents and take such other actions as may be reasonably requested from time
to time by any other party hereto as necessary to carry out, evidence, and
confirm the intended purposes of this Agreement.

     10.1 Certificate Regarding Schedules and Representations and Warranties.
The representations and warranties made by Seller in Article 6 shall be true
and correct in all material respects on and as of the Closing Date with the
same force and effect as though such representations and warranties had been
made on and as of the Closing Date (except that such representations and
warranties may be untrue or incorrect as a result of actions or transactions of
Seller made with the prior written consent of Parent), except to the extent
such representations and warranties expressly relate to an earlier date in
which case such representations and warranties shall remain true and correct in
all material respects on and as of such earlier date; and Parent and Newco
shall have received a certificate, dated as of the Closing Date, executed by an
authorized officer of Seller to such effect.  For purposes of this Section 10.1
only, in determining whether the condition to closing set forth herein has been
met, a representation or warranty shall be deemed true and correct in all
material respects notwithstanding a breach thereof if such breach does not
cause or would not reasonably be expected to cause a material adverse effect on
Seller's Indirect Merchant Network Business, provided, however, if (i) the
damages from the breach can be cured by money damages and (ii) the breach would
not materially interfere with the provision of services by Newco to its
customers, and (iii) if the amount of losses for which Newco would be entitled 
to receive indemnification pursuant to Section 15.2 (assuming for this purpose,
that the transaction had closed and the provisions of Article 15 were 
applicable) (x) can reasonably be determined prior to the Closing Date and the 
amount of such losses are paid to Newco on or prior to the Closing Date (less 
the Basket Amount described in Section 15.9, if applicable), or (y) cannot 
reasonably be determined prior the Closing Date but are not reasonably likely 
to exceed $20 million in the aggregate and the Seller confirms in writing that 
it is obligated pursuant to the terms of Article 15 to pay Newco the amount of 
such losses (less the Basket Amount described in Section 15.9, if applicable), 
then, and only in such event, the amounts paid or payable pursuant to Article 
15 shall be taken into account in making the determination whether the breach 
causes or would reasonably be expected to cause a material adverse effect on 
Seller's Indirect Merchant Network Business.

     10.2 Compliance by Seller.  Seller shall have duly performed in all
material respects all of the covenants and agreements contained in this
Agreement to be performed by it on or prior to the Closing Date, and Parent and
Newco shall have received a certificate, dated as of the Closing Date, executed

consummation of the transactions contemplated hereby, or enjoins or restricts
the operation of all or a material portion of the Acquired Assets in the manner
contemplated by this Agreement, which, in the reasonable judgment of Parent,
would make it inadvisable to consummate the transactions contemplated by this
Agreement.

                                   ARTICLE 11
                 CONDITIONS PRECEDENT TO OBLIGATIONS OF SELLER

     The obligation of Seller to consummate the transactions contemplated by
this Agreement shall be subject to the satisfaction, on or before the Closing
Date, of each of the following conditions, all or any of which may be waived in
writing, in whole or in part, by Seller:

     11.1 Certificate Regarding Schedules and Representations and Warranties.
The representations and warranties made by Parent in Article 7 shall be true
and correct in all material respects on and as of the Closing Date with the
same force and effect as though such representations and warranties had been
made on and as of the Closing Date (except that such representations and 
warranties may be untrue or incorrect as a result of actions or transactions 
of Parent made with the prior written consent of Seller), except to the extent 
such representations and warranties expressly relate to an earlier date in 
which case such representations and warranties shall remain true and correct 
in all material respects on and as of such earlier date; and Seller shall have 
received a certificate, dated the Closing Date, executed by an authorized 
officer of Parent to such effect.  For purposes of this Section 11.1 only, in 
determining whether the condition to closing set forth herein has been met, a 
representation or warranty shall be deemed true and correct in all material 
respect notwithstanding a breach thereof if such breach does not cause or 
would not reasonably be expected to cause a material adverse effect on 
Parent's Indirect Merchant Network Business, provided, however, if (i) the 
damages from the breach can be cured by money damages and (ii) the breach 
would not materially interfere with the provision of services by Newco to its 
customers, and (iii) if the amount of losses for which Newco would be entitled 
to receive indemnification pursuant to Section 15.3 (assuming for this purpose, 
that the transaction had closed and the provisions of Article 15 were 
applicable) (x) can reasonably be determined prior to the Closing Date
and the amount of such losses are paid to Newco on or prior to the Closing Date
(less the Basket Amount described in Section 15.9, if applicable), or (y)
cannot reasonably be determined prior the Closing Date but are not reasonably
likely to exceed $20 million in the aggregate and the Parent confirms in
writing that it is obligated pursuant and subject to the terms of Article 15 to
pay Newco the amount of such losses (less the Basket Amount described in
Section 15.9, if applicable), then, and only in such event, the amounts paid or
payable pursuant to Article 15 shall be taken into account in making the
determination whether the breach causes or would reasonably be expected to
cause a material adverse effect on Parent's Indirect Merchant Network Business.

     11.2 Compliance by Parent and Newco.  Each of Parent and Newco shall have
duly performed in all material respects all of the covenants and agreements
contained in this Agreement to be performed by them on or prior to the Closing
Date, and Seller shall have received a certificate, dated as of the Closing
Date, executed by an authorized officer of Parent and a Manager of Newco to
such effect.

to which Parent or Newco is a party and authorizing the negotiation, execution
and delivery of each Acquisition Document to which Parent or Newco is or will

rescinded, revoked, modified, or otherwise affected and remain in full force
and effect.

received a true and correct copy of each material consent and waiver that is
(a) required for the assignment of the Parent Contracts, Parent's Permits,
Parent's Intellectual Property, and other agreements and assets and (b)
otherwise required for the execution, delivery, and performance of this
Agreement by Parent.  All authorizations, orders, or approvals of any
governmental commission, board or other regulatory body required for Newco's
operation of Parent's Indirect Merchant Network Business after Closing or for
the consummation of the transactions contemplated hereby shall have been
obtained.  Seller shall have received a certificate, dated as of the Closing
Date, executed by an authorized officer of Parent to the foregoing effect, and
Seller shall be reasonably satisfied with the terms, conditions, and
restrictions of and obligations under each such authorization, order, or
approval.

     11.5 No Injunction; Etc.  No legislation, order or injunction shall be in
effect which enjoins, restrains, or prohibits Seller in respect of the
consummation of the transactions contemplated hereby, or restricts or enjoins
the operation of all or a material portion of the Parent Contributed Assets,
which, in the reasonable judgment of Seller, would make it inadvisable to
consummate in the manner contemplated by this Agreement the transactions
contemplated by this Agreement.

     11.6 Incumbency.  Seller shall have received certificates of incumbency of
Parent executed by its Secretary or Assistant Secretary and a certificate of

clear of all liens, charges, encumbrances, pledges, or claims of any nature 
except for Permitted Encumbrances.

     11.10 Leased Real Property Certificates.  Seller shall have received prior

consent to lease assignments for all Parent's Leased Real Property.

     11.12 Condition of Acquired Assets.  On the Closing Date, all of the

suffered loss or damage on account of fire, flood, accident, act of war, civil
commotion, or any other cause or event beyond the reasonable power and control
of Parent (whether or not similar to the foregoing) and Parent has maintained
in full force and effect the Parent Policies then the obligations of Seller to
consummate the transactions provided for in this Agreement shall not be excused
and at the Closing Parent shall assign to Newco all the right to be paid the

Except as otherwise provided in this Agreement, Parent, Newco and Seller shall
each refrain from knowingly taking or failing to take any action which would
render any of the representations or warranties contained in Articles 6 or 7 of
this Agreement in any material respect inaccurate as of the Closing Date.  Each
party shall promptly notify the other parties after learning of any action,

Item, and the Payee shall promptly pay such share to the Payor.  In the event
any party (the "Recipient") receives payments of a Proration Item to which
another party (the "Beneficiary") is entitled in whole or in part under this
Agreement, the Recipient shall promptly pay such share to the Beneficiary.

          (e) In the event there exist as of the Closing Date any pending 
appeals of ad valorem tax assessments with regard to any Acquired Assets or

     12.4 Access and Information.  From the date hereof to the Closing Date and

Merchant Network Business and shall furnish such persons with all information
(including financial and operating data) concerning Seller's Indirect Merchant
Network Business and the Acquired Assets as they reasonably may request.
Seller shall use commercially reasonable efforts to assist Parent and Newco,
their counsel, accountants, and other representatives in their examination.
Parent and Newco shall, and shall use their best efforts to cause their
counsel, accountants, and representatives to, hold in strict confidence all
information so obtained from Seller.

     12.5 Confidentiality.    Parent and Seller each agree that (i) all
information regarding either of them (the "Disclosing Party"), including any
subsidiaries of the Disclosing Party, which is or has been furnished to the
other (an "Evaluating Party") by the Disclosing Party or any of the Disclosing
Party's Representatives (as hereinafter defined) in connection with the
Evaluating Party's consideration and review of the transactions contemplated
hereby (the "Transaction") (such information, together with notes, memoranda,
summaries, analyses, compilations and other writings relating thereto or based
thereon prepared by the Evaluating Party or its Representatives being referred
to herein as the "Evaluation Material") will be kept strictly confidential.
The term "Evaluation Material" does not include information which becomes
generally available to the public through no wrongful act of the Evaluating
Party or its Representatives; which was publicly and generally available prior
to the date hereof; which is or was independently developed by the Evaluating
Party without any reference to the Evaluation Material; or which was or becomes
available to the Evaluating Party or any of its Representatives on a
non-confidential basis from a source other than the Disclosing Party or its
Representatives, provided that neither the Evaluating Party or its
Representatives is aware that such source is under an obligation (whether
contractual, legal or fiduciary) to the Disclosing Party to keep such
information confidential.  The term Representatives means the respective
party's directors, officers, employees, legal and financial advisors,


                                   - 54 -

accountants and other agents and representatives, as the case may be, and in
the case of Parent, includes any bank or other financial institution or
institutional investor who is considering providing financing to Parent or
Newco in connection with the Transaction.  If either the Seller or Parent is
requested in any judicial or administrative proceeding or by any governmental
or regulatory authority to disclose any Evaluation Material regarding the
other, such party will give the Disclosing Party prompt notice of such request
so that the Disclosing Party may seek an appropriate protective order.  Seller
and Parent agree to cooperate with the other in obtaining such an order.  If 
in the absence of a protective order Parent or Seller is nonetheless compelled 
to disclose the Evaluation Material regarding the other, such party may make 
such disclosure without liability hereunder, provided that such party gives the
other party written notice of the information to be disclosed as far in advance
of its disclosure as is practicable and, upon the Disclosing Party's request
and at the Disclosing Party's expense, use commercially reasonable efforts to
obtain reasonable assurances that confidential treatment will be accorded to
such information.  If this Agreement is terminated prior to the Closing, each
party shall promptly return or certify the destruction of all Evaluation
Material and copies thereof, and all work papers containing confidential
information received from each other party.  Newco and Parent's obligations
under this provision with respect to confidential information about the
Acquired Assets shall terminate upon the closing of the transactions
contemplated hereby.


                                   ARTICLE 13
                              POST CLOSING MATTERS


     13.1 Employment of Employees.

          (a) Newco shall make offers of employment no later than the business
day prior to the Closing Date, to be effective on the Closing Date, to all of
Seller's employees identified in SECTION 6.14 OF THE SELLER DISCLOSURE
MEMORANDUM ("Employees") other than:  Employees who are Not Actively Employed
by Seller on the Closing Date for any reason whatsoever, including but not
limited to a leave of absence or prior termination of employment (an Employee
shall be considered "Not Actively Employed" if the Employee did not report to
work with Seller for a period of at least six consecutive business days which
includes the Closing Date (excluding vacation time).  Newco's offer of
employment may be conditioned upon an Employee reporting to work as soon as
practicable after the Closing Date.

     Employees who are Not Actively Employed by Seller on the Closing Date due
to maternity leave, workers' compensation leave, Family Medical Leave Act of
1993 leave or leave under a similar state statute, and any other medical leave
or permitted leave of absence, who present themselves for work upon completion
of the leave with a written physician's statement acceptable to Newco that the
individual is fit to perform his or her job, shall be offered immediate
employment by Newco subject to the same requirements as stated in this
Paragraph 13.1(a) for offers to other Employees of Seller.


                                   - 55 -
<PAGE>   66


     Employees who accept the offer of employment made by Newco shall be
referred to as "Transferred Employees."  Notwithstanding any other provision of
this Agreement to the contrary, the wage and salary rate paid by Newco or
Parent, and the bonus opportunity (including the basis for determining the
extent to which a bonus will be paid and the amount of the potential bonus), 
applicable to any Transferred Employee from the Closing Date through December 
31, 1996 shall not be less that the wage and salary rate earned by such 
Transferred Employee from Seller, and the bonus opportunity in effect, 
respectively, as of the Closing Date; provided, however, that Seller shall be 
responsible for the ratable portion of any bonus for a Transferred Employee 
through the Closing Date and Newco shall be responsible for the ratable 
portion of any bonus after the Closing Date through December 31, 1996.

        (b) Notwithstanding any possible inferences to the contrary, none of
Seller, Parent or Newco intends for this Article 13 to create any rights or
obligations except as between the parties hereto, and no past, present or
future employees of Seller, Parent or Newco shall be treated as third-party
beneficiaries of this Article 13.

        (c) Seller shall be responsible for the payment of all wages,
commissions, severance pay, accrued vacation and sick pay to Transferred
Employees of Seller that are earned or accrued but not yet paid through the
Closing Date and for any Employees of Seller who are not Transferred Employees,
up to and including the date Seller terminates the employment of such
Employees.  Except for obligations specifically assumed by Newco hereunder,
Seller shall be responsible for the payment of any amounts due to its Employees
(including the Transferred Employees) pursuant to the Seller Benefit Plans as a
result of the employment of its Employees, provided that in determining bonuses
and other similar payments due to Transferred Employees for any period ended on
or prior to the Effective Time, Seller shall, if payment thereof will occur
after the Effective Time, waive any requirement that such Employees be
Employees of Seller on the date such bonuses or other similar payments are
paid.  Seller shall be responsible for reporting all employee-related costs and
liabilities of Transferred Employees accruing prior to the Closing Date,
whether payable on or after the Closing Date.  Seller is responsible for all
incurred but unreported or unpaid medical claims made, occurring or arising
prior to the Effective Time and for the cost associated with any hospital
confinement that commences prior to the Effective Time.  Effective on the
Closing Date, Seller shall, and hereby does, release all Transferred Employees
from any employment and/or confidentiality agreement previously entered into
between Seller and such Transferred Employees to the extent (but only to the
extent) necessary for Newco to operate Seller's Indirect Merchant Network
Business in substantially the same manner as operated by Seller prior to the
Closing Date.

        (d) Newco shall become responsible for all costs and liabilities
attributable to Transferred Employees accruing at and after the Effective Time;
provided, however, that Newco shall not be responsible for any liabilities
arising under the Seller Benefit Plans except as specified in Sections 13.3 and
13.4.

<PAGE>   67




     13.2 Seller's Benefit Plans.  Except for obligations specifically assumed
by Newco under this Agreement, Newco shall assume no responsibility with regard
to any Seller Benefit Plans.  To the extent necessary, Seller may continue to
communicate with the Transferred Employees regarding their rights and 
entitlement to any benefits under the Seller Benefit Plans in connection with 
the transactions contemplated hereby, subject to Newco's prior approval, which 
shall not be unreasonably withheld, and the parties shall cooperate with each 
other in the administration of all applicable employee benefit plans and 
programs.

     13.3 Vacation Pay.  Parent and Newco agree to give each Transferred
Employee credit for prior years of service with Seller for purposes of
calculating vacation pay that may be received pursuant to the vacation pay
policy of Newco as may be in effect from time to time after the Closing, and
will waive any eligibility requirements of such policy with respect to
Transferred Employees.  At the election of Newco, Newco shall either (i)
provide each Transferred Employee with the number of vacation days to which the
applicable Transferred Employee would be entitled for the year ended December
31, 1996 (less any vacation days previously taken) under Seller's vacation
policy in excess of the number of days for such year to which such Transferred
Employee would be entitled under Newco's vacation policy as of the Closing
Date, or (ii) include the value of such differences in vacation days in the
payments to be made pursuant to Section 13.4(g).

     13.4 Newco's Benefit Plans.

          (a) Under Newco's employee benefit plans and programs (including any
employee benefit plans of Parent which are made available to Newco's
employees), each Transferred Employee shall receive credit for prior years of
service with Seller for all purposes of such plans (except for purposes of
benefits accrued under a defined benefit plan) and shall be entitled to
participate in any such Newco employee benefit plans without the application of
any applicable waiting periods.  Newco and Parent shall also permit the
Transferred Employees and their eligible dependents to participate in their
applicable group medical plans and will cause such group medical plans to (i)
recognize all out-of-pocket expenses of each Transferred Employee recognized
from and after January 1, 1996 and prior to the Closing Date under Seller's
applicable group medical plans for purposes of determining each such
Transferred Employee's deductible and co-payment expenses for the year ended
December 31, 1996 under Newco's and Parent's applicable group medical plans and
(ii) waive any provisions that would exclude coverage of a pre-existing
condition of any Transferred Employee or any of the Transferred Employee's
dependents or beneficiaries to the extent that, as of the Closing Date, any
such condition was not subject to exclusion under Seller's applicable group
medical plan.

          (b) As soon as practicable following the Closing, Seller shall cause
the trustee ("Seller's Trustee") of the MasterCard Savings Plan ("Seller's
Retirement Plan"), to transfer to the trustee of Parent's 401(k) Plan
("Parent's Trustee") cash equal to the vested account balance (as of the day of
the transfer) of each Transferred Employee in Seller's 

                                   - 57 -
<PAGE>   68


Retirement Plan.  The cash to be transferred shall not include the value of the
account balances of any Transferred Employees who become eligible for and elect
to receive a distribution (including a direct rollover described in Internal
Revenue Code Section 401(a)(31)) from the Seller's Retirement Plan prior to the
date of transfer to Parent's 401(k) Plan.  As of the Closing Date, Seller shall
vest Transferred Employees in the non-vested portion of their account balances
in Seller's Retirement Plan.

        (c) Seller represents that Seller's Retirement Plan permits or will
permit the transfer of assets and liabilities described in Sections 13.4(b)
above.  To the extent required by law, Newco and Parent agree to provide for
the transfer of assets described in Section 13.4(b) above in Parent's 401(k)
Plan.  Parent's 401(k) Plan shall comply, without limitation, with Section
411(d)(6) of the Code with respect to accrued benefits represented by the
assets transferred from the Seller's Retirement Plan.

        (d) Neither Parent, Newco or Parent's Trustee shall be liable for
benefits to the Transferred Employees attributable to assets that are not
transferred from Seller's Trustee to Parent's Trustee.  Similarly, neither
Seller nor Seller's Trustee shall be liable for benefits to the Transferred
Employees attributable to assets that are transferred from Seller's Trustee to
Parent's Trustee.  Parent shall indemnify the Seller (as if Seller was Newco
for such purpose) in accordance with Section 15.3 of this Agreement against
Losses suffered by Seller that are attributable to the failure of Parent's
401(k) Plan and trust to qualify under Code Section 401(a).   Similarly, Seller
shall indemnify the Parent (as if Parent was Newco for such purpose) and Newco
in accordance with Section 15.2 of this Agreement against Losses suffered by
Parent that are attributable to the failure of Seller's Retirement Plan and
trust to qualify under Code Section 401(a).

        (e) Prior to the transfer of assets from Seller's Retirement Plan to
Parent's 401(k) Plan: (i) Parent shall provide to Seller written assurances
that the Parent's 401(k) Plan satisfies the requirements of Code Section 401(a)
and 401(k) and (ii) Seller shall provide to Parent written assurances that the
Seller's Retirement Plan satisfies the requirements of Code Section 401(a) and
401(k).

        (f) Seller, Parent and Newco shall, in connection with the transfer
described in this Section 13.4, cooperate in making all appropriate filings
required under the Code and ERISA and the regulations thereunder and in all
other ways cooperate in completing the transfer of assets and liabilities, and
shall further cooperate to ensure that the transfers described in this Section
13.4 satisfy the applicable requirements of Sections 401(a)(12), 401(k) and
414(l) of the Code and the regulations thereunder.

        (g) No later than 120 days following the Closing Date, Parent and
Seller shall jointly engage William M. Mercer Incorporated, or such other
benefits consultant as is mutually acceptable to Seller and Parent, to value by
December 1, 1996, the Parent and other benefits (on a per-employee basis) that
will be applicable to Transferred Employees employed by Newco through December
31, 1996.  No later than December 1, 1996, William M. Mercer Incorporated, or
such other benefit consultant as

                                   - 58 -
<PAGE>   69



was engaged to value Newco's benefits pursuant to the preceding sentence, shall
undertake a similar evaluation of Seller's benefits that would have applied to
each Transferred Employee had the Transferred Employee remained in the employ
of the Seller.  Newco shall, no later than March 31, 1997, make a single cash
payment (a "Benefits Equalization Payment") to each Transferred Employee (i)
employed by Newco at the time of the payment and (ii) each Transferred Employee
terminated by Newco without cause after December 31, 1996 and before the date
of the payment, in each case, equal to the excess, if any, of the value (for
the period beginning on the Closing Date through December 31, 1996) of Seller's
benefits which would have applied to such Transferred Employee in excess of the
value of Newco's benefits for such Transferred Employee for such period.

          (h) Newco shall offer Transferred Employees relocation benefits under
the same terms and conditions as under the relocation benefit program of
Seller, provided that Seller, for the duration of such program, shall be
responsible for paying any and all costs of providing such relocation benefits.

          (i) Newco shall provide severance benefits to Transferred Employees
whose employment is involuntarily terminated by Newco through December 31, 1996
substantially similar to the Seller's Severance Policy described in SECTION
6.17 OF THE SELLER DISCLOSURE MEMORANDUM as in effect on the date hereof.
Except as provided in the foregoing sentence, following the Closing Date Newco
shall adopt a severance program applicable to all employees in its sole
discretion and, as of January 1, 1997, all employees of Newco, including
Transferred Employees, shall be subject to such policy as in effect from time
to time.

     13.5 Non-Solicitation.  Until the expiration of thirty-six (36) months
after the month in which the Closing Date occurs, Seller shall not directly or
indirectly solicit or offer employment to any Transferred Employee who is then
an employee of Newco or who has terminated such employment without the consent
of Newco within ninety (90) days of such solicitation or offer, and neither
Parent nor Newco shall directly or indirectly solicit or offer employment to
any person who, after the Closing Date, is then an employee of Seller or who
has terminated such employment without the consent of Seller within ninety (90)
days of such solicitation or offer.

     13.6 Discharge of Business Obligations.  From and after the Closing Date,
Seller shall pay and discharge, in accordance with past practice but not less
than on a timely basis, all obligations and liabilities incurred by it prior to
the Effective Time in respect of Seller's Indirect Merchant Network Business,
its operations or the assets and properties used therein (except for
liabilities and obligations expressly assumed by Newco hereunder), including
without limitation any liabilities or obligations to employees and clients of
Seller.  From and after the Closing Date, Parent shall pay and discharge, in
accordance with past practice but not less than on a timely basis, all
obligations and liabilities incurred by it prior to the Effective Time in
respect of Parent's Indirect Merchant Network Business, its operations or the 
assets and properties used therein (except for 

                                   - 59 -
<PAGE>   70


liabilities and obligations expressly assumed by Newco hereunder).  Likewise, 
from and after the Closing Date, Newco shall pay and discharge, in accordance 
with the past practice of Seller's Indirect Merchant Network Business but not 
less than on a timely basis, all obligations and liabilities expressly assumed 
by Newco hereunder.

     13.7 Maintenance of Books and Records.

          (a) Each of Seller, Parent and Newco shall preserve until the seventh
anniversary of the Closing Date all Books and Records possessed or to be
possessed by such party relating to any of the assets, liabilities or business
of Seller's Indirect Merchant Network Business prior to the Closing Date.
Seller shall give Newco written notice of any Books and Records discovered by
Seller that were not transferred to Newco.  After the Closing Date, where there
is a legitimate purpose, each party shall provide the other with access, upon
prior reasonable request specifying the need therefor, during regular business
hours, to (i) the officers and employees of such party and (ii) the books of
account and records of such party, but, in each case, only to the extent
relating to Seller's Indirect Merchant Network Business prior to the Closing
Date, and the other party and its representatives shall have the right to make
copies of such books and records; provided, however, the foregoing right of
access shall not be exercisable in such a manner as to interfere unreasonably
with the normal operations and business of such party; and further, provided,
as to so much of such information as constitutes trade secrets or confidential
business information of such party, the requesting party, its affiliates,
officers, directors and representatives will use due care to not disclose such
information except (i) as required by law, (ii) with the prior written consent
of such party, which consent shall not be unreasonably withheld, or (iii) where
such information becomes available to the public generally, or becomes
generally known to competitors of such party, through sources other than the
requesting party, its affiliates or its officers, directors or representatives.
Notwithstanding the provisions of this Section 13.7(a), such records may be
destroyed by a party if such party sends to the other parties written notice of
its intent to destroy records, specifying with particularity the contents of
the records to be destroyed; provided, however, that neither party shall give
the other written notice of its intent to destroy records, if such records are
at such time legally required to be maintained.  Records with respect to which
such notice is given may then be destroyed after the 30th day after such notice
is given, unless another party objects to the destruction in which case the
party seeking to destroy the records shall deliver such records to the
objecting party.

          (b) Newco shall fully cooperate with Seller in the preparation and
filing of all tax filings relating to the period ending prior to the Closing
Date. Newco also shall make available to Seller such information as may be
reasonably required by Seller in connection with audits or otherwise for the
proper payment of taxes for which Seller is responsible or in connection with
any claims for refunds of such taxes.  Newco shall provide within a reasonable
time after the receipt of a written request all information contained in its 
files necessary for the preparation by Seller of a Form W-2 for the calendar 
year in which the Closing occurs for each Transferred Employee.


                                   - 60 -
<PAGE>   71



     13.8 Payments Received.  Seller and Newco agree that after the Closing
they will hold and will promptly transfer and deliver to the proper recipient
thereof, from time to time as and when received by them, any cash, checks with
appropriate endorsements (using their best efforts not to convert such checks
into cash), or other property that they may receive on or after the Closing
which properly belongs to the other party, including without limitation, any
insurance proceeds, and will account to the other for all such receipts.  From
and after the Closing, Newco shall have the right and authority to endorse
without recourse the name of Seller on any check or draft for payment of money
received by Newco on account of the Acquired Assets transferred to Newco
hereunder.

     13.9 Covenants Not to Compete; Confidentiality.

          (a) Seller agrees, as consideration for the consummation of the
transactions contemplated herein and for the payment to be made pursuant to
Section 3.1(a) hereof, for a period commencing on the Closing Date and ending
four (4) years after the date Seller ceases to be the beneficial owner of any
equity interest in Newco or any successor thereto, Seller (i) will not, either
directly or indirectly (including through any Affiliate), own, manage, control
or operate or participate in the ownership, management, operation or control
of, any business whether in corporate proprietorship or partnership form or
otherwise, which is engaged in the Business of Newco (as hereinafter defined)
as conducted as of the Closing Date (a "Competitive Activity") in the United
States (the "Territory"); (ii) will not engage in a Competitive Activity at any
place in the Territory  directly or indirectly (including through an
Affiliate), whether individually, in partnership, jointly, or in conjunction
with, or on behalf of, any person, firm, partnership, corporation, or
unincorporated association or entity of any kind; and (iii) will not, directly
or indirectly (including through an Affiliate), whether individually, in
partnership, jointly, or in conjunction with, or on behalf of, any person,
firm, partnership, corporation, or unincorporated association or entity of any
kind, solicit or accept any Business of Newco from any bank or other
association or institution that acts as a depository or processor of any
transactions utilizing credit cards, debit cards or similar cards on behalf of
merchants.  As used herein, the "Business of Newco" means (i) Merchant
generated electronic authorization and data capture and transaction processing
for Credit Cards both directly from Merchant point-of-sale terminals and from a
Merchant's host/controller, (ii) front end processing and back office support,
and (iii) the provision of corporate cash management and information services
both directly to corporations and indirectly through financial institutions,
including bank account balance and deposit reporting, institutional wire
transfer, financial electronic data interchange as a separate product and
electronic tax payment and filing services; provided, however, that Seller
shall not be deemed to be violating the covenants contained herein if it
engages in any of the activities set forth in (iii) above and  these services
are reasonably required to be provided in order to support the issuance,
acceptance and utilization of credit, debit, corporate, purchase and other
card-related products on behalf of Seller's membership and not as a separate
product or service.  If at any time the provisions of this Section 13.9 are in
effect Seller desires to engage in an activity that is or may be prohibited by
this Section 13.9, and Seller reasonably believes that such activity would not
compete with the Business of Newco, 

                                   - 61 -
<PAGE>   72


Seller may seek approval for such activity from Newco, and Newco agrees not to 
unreasonably withhold such approval.

        (b) Seller acknowledges that it has information in respect of Seller's
Indirect Merchant Network Business and financing of Seller's Indirect Merchant
Network Business and its dealings, transactions, affairs, plans and proposals,
some of which information is confidential and important to Seller's Indirect
Merchant Network Business.  In this Section 13.9 such confidential and
important information is called "Newco Confidential Information" and includes,
without limitation, confidential or secret information relating to the trade
secrets, know-how, ideas, business methods, finances, prices, business plans,
marketing plans, development plans, manpower plans, sales targets, sales
statistics, customer lists, customer relationships, computer systems and
computer software of Seller's Indirect Merchant Network Business.  Seller
further acknowledges that the disclosure of Newco Confidential Information
(whether directly or indirectly) to actual or potential competitors of Seller's
Indirect Merchant Network Business could place Newco at a competitive
disadvantage and could do damage (whether financial or otherwise) to Newco's
business.  Seller shall not during the period commencing on the Closing Date
and terminating on the fifth anniversary of the Closing Date (i) disclose to
any person except to those authorized by Parent or Newco to know any Newco
Confidential Information; or (ii) through failure to exercise reasonable care
and diligence cause or permit any unauthorized disclosure of any Newco
Confidential Information; provided, however, that these restrictions shall
cease to apply to information which (otherwise than through the default of
Seller) becomes available to the public generally; provided, further, that
nothing herein shall prevent Seller or its Affiliates from using Seller
Confidential Information in the normal conduct of carrying out their own
business, Seller agreeing that they shall not be entitled to use any Newco
Confidential Information in a manner that would breach subsection (a) of this
Section 13.9; and provided further that none of the restrictions contained in
this Section 13.9 shall be binding on any of the members of Seller provided
that such members did not obtain such Newco Confidential Information pursuant
to a breach by Seller of its obligations hereunder.

        (c) Parent and Newco acknowledge that each of them has or will have,
through the Transferred Employees, information in respect of the business of
Seller other than Seller's Indirect Merchant Network Business and financing of
the business of Seller other than Seller's Indirect Merchant Network Business
and its dealings, transactions, affairs, plans and proposals, certain of which
information is confidential and important to the business of Seller.  In this
Section 13.9 such confidential and important information is called "Seller
Confidential Information" and includes, without limitation, confidential or
secret information relating to the trade secrets, know-how, ideas, business
methods, finances, prices, business plans, marketing plans, development plans,
manpower plans, sales targets, sales statistics, customer lists, customer
relationships, computer systems and computer software of the business of Seller
other than Seller's Indirect Merchant Network Business.  Parent and Newco
further acknowledge that the disclosure of Seller Confidential Information
(whether directly or indirectly) to actual or potential competitors of the
business of Seller other than Seller's Indirect Merchant Network Business
could 

                                   - 62 -
<PAGE>   73


place Seller at a competitive disadvantage and could do damage (whether
financial or otherwise) to Seller's business other than Seller's Indirect
Merchant Network Business.  Parent and Newco shall not during the period
commencing on the Closing Date and terminating on the fifth anniversary of the
Closing Date (i) disclose to any person except to those authorized by Seller to
know any Seller Confidential Information; or (ii) through failure to exercise
reasonable care and diligence cause or permit any unauthorized disclosure of
any Seller Confidential Information; provided, however, that these restrictions
shall cease to apply to information which (otherwise than through the default
of Parent or Newco) becomes available to the public generally; provided,
further, that nothing herein shall prevent Parent, Newco or its Affiliates from
using Seller Confidential Information in the normal conduct of carrying out
their own business.

           (d) To the extent that Seller desires to provide after the Closing a
new service to one or more of its members in Canada or Mexico and such new
service would be competitive with the Business of Newco if such new service was
provided in the United States, Seller will give Newco notice thereof and an
opportunity to be considered to provide such service to Seller's member or
members on terms satisfactory to Seller (unless the applicable Seller member or
members specifically request that Newco not be given such notice of
opportunity); provided, however, that in no event will Seller be required to
give such notice or opportunity if it would delay the implementation of such
service; and provided further that the foregoing right of Newco to notice and
opportunity shall not apply with respect to the provision of any future service
in development by Seller as of the Closing.  The undertakings in this Section
13.9(d) shall expire when the covenant not to compete in Section 13.9(a)
expires.

           (e) The parties hereto specifically acknowledge and agree that the
remedy at law for any breach of the foregoing will be inadequate and that the
aggrieved party, in addition to any other relief available to it, shall be
entitled to temporary and permanent injunctive relief without the necessity of
proving actual damage.  In the event that the provisions of this Section 13.9
should ever be deemed to exceed limitations provided by applicable law, then
the parties hereto agree that such provisions shall be reformed to set forth
the maximum limitations permitted; provided, however, nothing in this Section
13.9 shall prevent Seller or any affiliate of Seller from (i) acquiring all or
a portion of the stock or assets of a public company which is engaged in a
Competitive Activity  if the revenues from such Competing Activity comprise
less than 5% of the total revenues of such public company or the business
represented by such assets; or (ii) acquiring less than a 2% ownership interest
in a company which is engaged in a Competitive Activity.

     13.10 Cooperation.  Seller, Parent and Newco shall cooperate with each
other in all reasonable respects in connection with the defense or prosecution
of any claim included within any Assumed Liability or Excluded Liability or any
Acquired Asset or Excluded Asset, as the case may be, including making
available records relating to such claim and furnishing, without expense,
management employees of the party as may be reasonably necessary for the
preparation of the defense of any such claim or for testimony as a 

                                   - 63 -
<PAGE>   74


witness in any proceeding relating to such claim; provided, however, that the 
foregoing right to cooperation shall not be exercisable by one party in such a 
manner as to interfere unreasonably with the normal operations and business of 
the other party.

     13.11 Delivery of Documents.  Subject to the terms and conditions hereof,
each of Seller, Parent, and Newco, as applicable, shall execute and deliver the
Seller Transition Services Agreement, the Registration Rights Agreement, the
Operating Agreement, the Parent Services Agreement, the Assignment and
Assumption Agreeement, the Newco Assignment and Assumption Agreement and the
subleases contemplated in this Agreement.

     13.12 Cooperation and Marketing.

           (a) Newco shall have the right to utilize the description "A Limited
Liability Company of National Data Corporation and MasterCard International
Incorporated" on Newco's corporate stationery until such time as Seller ceases
to own an equity interest in Newco; provided, however, that after notice to
Newco, Seller shall have the right to terminate Newco's right to utilize
Seller's name on Newco's corporate stationary if Newco commits a breach (as
defined in SECTION 13.12(A) OF THE SELLER DISCLOSURE MEMORANDUM) of any of the
performance standards  set forth in SECTION 13.12(A) OF THE SELLER DISCLOSURE
MEMORANDUM.

           (b) Provided that Newco shall have registered as a member service
provider ("MSP"), (i) Newco shall retain all rights afforded to MSP's, and (ii)
in the event Seller grants more extensive rights to use the Seller's name than
that granted to MSP's in general, Newco shall receive the same more extensive
rights to use the Seller's name.

           (c) Disposition of Existing Materials Containing Seller's Name or 
Mark. Newco shall have the right to use four (4) categories of materials in 
which the Seller's name and associated marks (other than the MAPP mark 
included in the Acquired Assets) are included, as follows:

               (i) Marketing Materials.  Newco shall have the right to use 
existing sales and marketing materials until the earlier to occur of ninety 
(90) days or reorder, at which time all remaining MAPP/Seller materials shall 
be returned to Seller for subsequent destruction.

               (ii) User Manuals.  Consistent with subparagraph (i) above and 
based upon existing inventory considerations, Newco shall have the right to 
use existing user manuals until the earlier to occur of one hundred eighty 
(180) days or reorder, at which time all MAPP/Seller materials shall be 
replaced by Newco and all existing inventory shall be returned to Seller for 
subsequent destruction.

               (iii) Software.  Newco shall have the right to use the MAPP-PC 
and MAPP On-line software products in which the Seller logo is embedded as of 
the

                                   - 64 -
<PAGE>   75


Closing Date until such time as new software products (including upgrades of
software products shipped to existing users) are shipped by Newco.  After the
Closing Date, new software shall be modified to eliminate references to Seller
or its marks.

              (iv) Terminals.  The parties agree that the Seller acceptance mark
displays (located together with Visa, Novus and Amex mark displays) at the
point-of-sale at Merchant are addressed under the Seller's bylaws and rules.
With respect to the MAPP and Seller marks located on the faceplate of
point-of-sale terminals which are designed and defined by acquiring banks and
visible only to the merchant, it is agreed that (i) upon the earlier to occur
of one hundred eighty (180) days or reorder by Newco, all new faceplates shall
be printed without the Seller name or any Seller mark (other than the MAPP mark
which is included in the Acquired Assets); and (ii) as point-of-sale terminals
are replaced or redeployed, Newco shall use its best efforts to remove the
Seller's marks (other than the MAPP mark which is included in the Acquired
Assets) from such terminals.

          (d) Future Marketing and Promotional Affiliation.  Seller agrees to
support Newco in future marketing and promotion affiliation activities,
including, without limitation, as follows:

                                  TERMINATION


     14.1 Termination.  This Agreement may be terminated:

          (a) by the mutual consent of Parent and Seller;

          (b) by Parent if any condition in Article 10 becomes impossible of
performance or has not been satisfied in full or previously waived by Parent in
writing at or prior to the Closing Date;


                                   - 65 -
<PAGE>   76


          (c) by Seller if any condition in Article 11 becomes impossible of
performance or has not been satisfied in full or previously waived by Seller in
writing at or prior to the Closing Date;

          (d) by either party if the Closing has not occurred on or prior to May
31, 1996.

     14.2 Effect of Termination.  In the event of the termination and
abandonment hereof pursuant to the provisions of Section 14.1(a) hereof, this
Agreement shall become void and have no effect, without any liability on the
part of any of the parties hereto or their directors, or officers or
stockholders in respect of this Agreement, except that the provisions of this
Section 14.2, 12.5 and 16.1 of this Agreement shall survive any such
termination.  If Parent terminates this Agreement pursuant to Section 14.1(b)
or 14.1(f), or Seller terminates this Agreement pursuant to Section 14.1(c) or
14.1(f) and such termination is the result of the representations and
warranties of a non-terminating party being incorrect when made or thereafter
or the breach by a non-terminating party of a covenant or agreement hereunder,
then the party terminating this Agreement shall have such rights and remedies
against the other party hereto with respect to the condition giving rise to
such termination as are provided by law or in equity.

          (b) If the Indemnification Claim involves a Third Party Claim the
procedures set forth in Section 15.5 hereof shall be observed by the Indemnitee
and the Indemnitor.

          (c) If the Indemnification Claim involves a matter other than a Third
Party Claim, the Indemnitor shall have thirty (30) days to object to such
Indemnification Claim by delivery of a written notice of such objection to such
Indemnitee specifying in reasonable detail the basis for such objection.
Failure to so object within such thirty-day period shall constitute a final and
binding acceptance of the Indemnification Claim by the Indemnitor, and the
Indemnification Claim shall be paid in accordance with subsection (d) hereof.
If an objection is timely interposed by the Indemnitor and the dispute is not
resolved by such Indemnitee and the Indemnitor within fifteen (15) days from
the date the Indemnitee receives such objection, such dispute shall be resolved
by arbitration as provided in Section 16.13 of this Agreement.

          (d) Upon determination of the amount of an Indemnification Claim,
whether by agreement between the Indemnitor and the Indemnitee or by an
arbitration award or by any other final adjudication, the Indemnitor shall pay
the amount of such Indemnification Claim within ten (10) days of the date such
amount is determined.

     15.5 Third Party Claims.  The obligations and liabilities of the parties
hereunder with respect to a Third Party Claim shall be subject to the following
terms and conditions:

          (a) The Indemnitee shall give the Indemnitor written notice of the
commencement or institution of or, if earlier, the written assertion of any
claim or other written notice of an intention to assert a Third Party Claim
promptly after receipt by the Indemnitee of notice thereof, and the Indemnitor
may, except as set forth in subsections (b) and (c) of this Section 15.5,
undertake the defense, compromise and settlement thereof by representatives of
its own choosing reasonably acceptable to the Indemnitee.  The failure of the
Indemnitee to notify the Indemnitor of such claim promptly shall not relieve


                                   - 68 -
<PAGE>   79



the Indemnitor of any liability that it may have with respect to such claim
except to the extent the Indemnitor is prejudiced or adversely affected by such
failure.  The assumption of the defense, compromise and settlement of any such
Third Party Claim by the Indemnitor shall be an acknowledgment of the
obligation of the Indemnitor to indemnify the Indemnitee with respect to such
claim hereunder.  If the Indemnitee desires to participate in, but not control,
any such defense, compromise and settlement, it may do so at its sole cost and
expense.  If, however, the Indemnitor fails or refuses to undertake the defense
of such Third Party Claim within thirty (30) days after written notice of such
claim has been given to the Indemnitor by the Indemnitee, the Indemnitee shall
have the right to undertake the defense, compromise and settlement of such
claim with counsel of its own choosing; provided that the Indemnitee may take
such action in the defense of such action pending receipt of notice from the
Indemnitor of its agreement or refusal to undertake the defense of such Third
Party Claim as is deemed by the Indemnitee to be reasonably required under the
circumstances. In the circumstances described in the preceding sentence, the
Indemnitee shall, promptly upon its assumption of the defense of such claim,
make an Indemnification Claim as specified in Section 15.4 which shall be
deemed an Indemnification Claim that is not a Third Party Claim for the
purposes of the procedures set forth herein.

        (b) If, in the reasonable opinion of the Indemnitee, any Third Party
Claim or the litigation or resolution thereof involves an issue or matter which
could have a material adverse effect on the business, operations, assets,
properties or prospects of the Indemnitee (including, without limitation, the
administration of the tax returns and responsibilities under the tax laws of
the Indemnitee), which material adverse effect cannot be adequately compensated
by payments of money hereunder, then the Indemnitee shall have the right to
control the defense, compromise and settlement of such Third Party Claim
undertaken by the Indemnitor, and the costs and expenses of the Indemnitee in
connection therewith shall be included as part of the indemnification
obligations of the Indemnitor hereunder.  If the Indemnitee shall elect to
exercise such right, the Indemnitor shall have the right to participate in, but
not control, the defense, compromise and settlement of such Third Party Claim
at its sole cost and expense.

        (c) No settlement of a Third Party Claim involving the asserted
liability of the Indemnitor under this Article shall be made without the prior
written consent by or on behalf of the Indemnitor, which consent shall not be
unreasonably withheld or delayed.  Consent shall be presumed in the case of
settlements of $20,000 or less where the Indemnitor has not responded within
five (5) business days of notice of a proposed settlement.  If the Indemnitor
assumes the defense of such a Third Party Claim, (a) no compromise or
settlement thereof may be effected by the Indemnitor without the Indemnitee's
consent unless (i) there is no finding or admission of any violation of law or
any violation of the rights of any person and no effect on any other claim that
may be made against the Indemnitee, (ii) the sole relief provided is monetary
damages that are paid in full by the Indemnitor, and (iii) the compromise or
settlement includes, as an unconditional term thereof, the giving by the
claimant or the plaintiff to the Indemnitee of a release, in form and substance
reasonably satisfactory to the Indemnitee, from all liability 

                                   - 69 -
<PAGE>   80


in respect of such Third Party Claim, and (b) the Indemnitee shall have no 
liability with respect to any compromise or settlement thereof effected 
without its consent. Except in circumstances described in the immediately 
preceding sentence in which the Indemnitor may effect a compromise or 
settlement without the consent of the Indemnitee, if there is a dispute 
between the Indemnitor and the Indemnitee concerning whether a Third Party 
Claim should be settled, compromised or contested, then it shall be settled, 
compromised or contested in accordance with the next succeeding paragraph; 
provided, however, that the Indemnitee shall neither (A) be required to refrain 
from paying or satisfying any obligation that has matured by court judgment or 
decree, unless appeal is taken thereafter and proper appeal bond is posted by 
the Indemnitor, nor (B) shall the Indemnitee be required to refrain from 
paying or satisfying any Third Party Claim after and to the extent such Third 
Party Claim has resulted in (I) an unstayed injunction or other equitable 
relief against the Indemnitee or (II) in the imposition of a lien upon any of 
the properties or assets then held by the Indemnitee (unless such claim shall 
have been discharged or enforcement thereof stayed by filing of a legally 
permitted bond by the Indemnitor at its sole cost and expense) or (III) in a 
material breach or default in a material lease, license or other contract by 
which the Indemnitee is bound.

     Subject to the immediately preceding paragraph, in the event that the
Indemnitor, on the one hand, or the Indemnitee, on the other hand, has reached
a good faith, bona fide settlement agreement or compromise, subject only to
approval hereunder, with any claimant regarding a matter which may be the
subject of indemnification hereunder and which it desires to settle on the
basis of such agreement or compromise, such party who desires to so settle or
compromise shall notify the other party in writing of its desire setting forth
the terms of such settlement or compromise (the "Notice of Settlement").  The
Third Party Claim may be settled or compromised on the basis set forth in the
Notice of Settlement unless within twenty (20) days after the receipt of the
Notice of Settlement the party who issued the Notice of Settlement receives a
notice from the other party of its desire to continue to contest the matter
(the "Notice to Contest") and, in such case:

               (i) Should the Indemnitee deliver a Notice to Contest, the 
claim shall be so contested and the liability of the Indemnifying Party shall 
be limited as provided in subsection (iii) below.

               (ii) If the settlement or compromise could result in a claim for
indemnification being made against the Indemnifying Party and if the
Indemnifying Party delivers the Notice to Contest, the claim shall be so
contested and the liability of the Indemnitee shall be limited as provided in
subsection (iii) below.

               (iii) If a matter is contested as provided in subsections (i) 
or (ii) above and is later adjudicated, settled, compromised or otherwise 
disposed of and such adjudication, compromise, settlement or disposition 
results in a liability, loss, damage or injury in excess of the amount for 
which one party desired previously to settle the matter, then the liability of 
such party shall be limited to such lesser proposed settlement amount and the 
party contesting the matter shall be solely responsible for the amount in 
excess of 

                                   - 70 -
<PAGE>   81


such lesser proposed settlement and without regard to any limitations on the 
Indemnitor's obligation to indemnify set forth in this Article 15.

For an Indemnifying Party's Notice to Contest to be effective, it must also
state that the Indemnifying Party acknowledges and agrees that it shall be
obligated to indemnify the Indemnitee for any amount in excess of the lesser
proposed settlement amount as described in subsection (iii) above.  Except for
such obligation for the excess of the lesser proposed settlement amount
acknowledged in a Notice to Contest, the giving of or failure to give a Notice
to Contest by any party shall not be construed or implied as an acknowledgment
by such party of an obligation for indemnification under this Article 15.

          (d) In connection with the defense, compromise or settlement of any
Third Party Claim, the parties to this Agreement shall execute such powers of
attorney as may reasonably be necessary or appropriate to permit participation
of counsel selected by any party hereto and, as may reasonably be related to
any such claim or action, shall provide access to the counsel, accountants and
other representatives of each party during normal business hours to all
properties, personnel, books, tax records, contracts, commitments and all other
business records of such other party and will furnish to such other party
copies of all such documents as may reasonably be requested (certified, if
requested).

     15.6 Remedies.  Following the Closing, the rights and remedies of the
Indemnitees under this Article 15 are and shall be the exclusive remedies
available to any party for any misrepresentation under Article 6 or Article 7
or any breach of any representation or warranty set forth in Article 6 or
Article 7 of this Agreement.

     15.7 Survival.  All representations, warranties and agreements contained
in this Agreement or in any certificate delivered pursuant to this Agreement
shall survive the Closing notwithstanding any investigation conducted with
respect thereto or any knowledge acquired as to the accuracy or inaccuracy of 
any such representation or warranty.

     15.8 Time Limitations.  The Indemnitor shall have no liability under (i)
Section 15.2(a) with respect to the breach of any representation or warranty
contained in Article 6, unless on or before the second anniversary of the
Closing Date the Indemnitor is given notice asserting an Indemnification Claim
with respect thereto; or (ii) Section 15.3(a) with respect to the breach of
any representation or warranty contained in Article 7, unless on or before the
second anniversary of the Closing Date the Indemnitor is given notice asserting
an Indemnification Claim with respect thereto. An Indemnification Claim based
upon the failure of the Indemnitor to perform the covenants and agreements to
be performed by them hereunder pursuant to Section 5.2, 5.3, 12.5, 13.1, 13.2,
13.3, 13.4, 13.5, 13.6, 13.7, 13.8, 13.9, 13.10 or 13.12 or based upon Section
15.2(c), 15.3(c), 15.3(d), 15.3(e) or 15.3(f) hereof may be made at any time;
and the Indemnitor shall have no liability based upon the failure of the
Indemnitor to perform any other covenant or agreement to be performed by them
hereunder unless on or before the second anniversary of the Closing 

                                   - 71 -
<PAGE>   82


Date the Indemnitor is given notice asserting an Indemnification Claim with 
respect thereto.

     15.9 Amount Limitations.  Neither Seller nor Parent shall have any
obligation to indemnify the Indemnitees under Section 15.2(a) or 15.3(a),
respectively, with respect to the breach of any representation or warranty
until the aggregate Losses of the Indemnitees with respect to breaches of the
representations and warranties exceeds Five Hundred Thousand Dollars
($500,000)(the "Basket Amount"), at which time the Indemnitees may make claims
for all Losses in excess of the Basket Amount.  The Indemnitees shall not be
entitled to recover from Seller or Parent on account of such Losses any amount
in excess of Fifty Million Dollars ($50,000,000).

     15.10 Subrogation.  Upon payment in full of any Indemnification Claim,
whether such payment is effected by set-off or otherwise, or the payment of any
judgment or settlement with respect to a Third Party Claim, the Indemnitors
shall be subrogated to the extent of such payment to the rights of the
Indemnitee against any person or entity with respect to the subject matter of
such Indemnification Claim or Third Party Claim.

     15.11 Tax Neutralization.

     (a) In the event an Indemnification Claim hereunder results in a tax
benefit to the Indemnitee, the Indemnitor shall be entitled to a credit against
any liability thereunder in the amount by which (i) the present value of the
federal and state income taxes of the Indemnitee shall be reduced by reason of
any deduction allowed the Indemnitee for any payment, settlement or
satisfaction of such Indemnification Claim, exceeds (ii) the present value of
the federal and state income taxes payable by the Indemnitee from the
Indemnitor by reason of any payment under this Article 15.

     (b) In the event an Indemnification Claim hereunder results in a tax
burden to the Indemnitee, the Indemnitor shall reimburse the Indemnitee for any
additional tax liability incurred thereunder in the amount by which (i) the
present value of the federal and state income taxes of the Indemnitee shall be
increased by reason of any payment, settlement or satisfaction of such
Indemnification Claim being deemed income, is less than (ii) the present value
of the federal and state income taxes payable by the Indemnitee from the
Indemnitor by reason of any payment under this Article 15.

                                   ARTICLE 16
                               GENERAL PROVISIONS

     16.1 Fees and Expenses.  Except as otherwise specifically provided in this
Agreement, Seller and Parent shall pay their respective fees and expenses in
connection with the transactions contemplated by this Agreement.
Notwithstanding anything to the contrary set forth herein, Seller and Parent
each agree to pay one-half (1/2) of the filing fees payable for all required
filings under the HSR Act with respect to the transactions contemplated
hereunder.  Seller shall not pay any Excluded Liabilities or any fees or

                                   - 72 -
<PAGE>   83



expenses incurred by Seller in connection with the transactions contemplated by
this Agreement using the Acquired Assets or any portion thereof, and if prior
to the Effective Time a portion of the Acquired Assets is used by Seller to pay
any Excluded Liabilities, or any of such fees and expenses, Seller shall
reimburse Parent by the amount of Acquired Assets so used and the amount of
such reimbursement shall be deemed an Acquired Asset.

     16.3 Assignment; Binding Effect.  Except as provided in this Section 15.3,
prior to the Closing, this Agreement shall not be assignable by either of the
parties hereto without the written consent of the other; provided, however,
that after the Closing, Parent or Seller may assign its interest in this
Agreement to any person or entity without the consent of Seller, in the case of
an assignment by Parent, or of Parent, in the case of an assignment by Seller;
provided that, in the event of any such assignment, the assignee assumes the

in the event of any such assignment, if any consent to such assignment is
required, then the assigning party shall be responsible for obtaining such
consent and the non-assigning party will have no obligation to assist in any

     16.4 No Benefit to Others.  The representations, warranties, covenants,

assigns, and they shall not be construed as conferring any rights on any other
persons.

     16.5 Headings, Gender, and "Person."  All section headings contained in
this Agreement are for convenience of reference only, do not form a part of
this Agreement and shall not affect in any way the meaning or interpretation of
this Agreement.  Words used herein, regardless of the number and gender
specifically used, shall be deemed and construed to include any other number,
singular or plural, and any other gender, masculine, feminine, or neuter, as

against which the enforcement of such change, waiver, discharge, or termination
is sought.

     16.8 Time of Essence.  Time is of the essence in this Agreement.

     16.9 Governing Law.  This Agreement shall be construed under the laws of
the State of Georgia, without regard to any applicable conflicts of laws
provisions.

     16.10 Partial Invalidity.  Whenever possible, each provision hereof shall
be interpreted in such manner as to be effective and valid under applicable
law, but in case any one or more of the provisions contained herein shall, for
any reason, be held to be invalid, illegal, or unenforceable in any respect,
such invalidity, illegality, or unenforceability shall not affect any other
provisions of this Agreement, and this Agreement shall be construed as if such
invalid, illegal, or unenforceable provision or provisions had never been
contained herein unless the deletion of such provision or provisions would
result in such a material change as to cause completion of the transactions
contemplated hereby to be unreasonable.

     16.11 Investigation.  No inspection, preparation, or compilation of
information or the Seller or Parent Disclosure Memoranda, or audit or
investigation of the  properties, financial condition, or other matters
relating to Seller or Parent conducted by or on behalf of the other party
hereto shall in any way limit, affect, or impair the ability of Parent or
Seller, as the case may be, to rely upon the representations, warranties,
covenants, and agreements of the other party set forth herein.  Any disclosure
made in one Section of the Seller or Parent Disclosure Memoranda shall not be
deemed made in any other Section, unless appropriate cross-referencing is made.
The covenants and representations and warranties of the parties hereto shall
survive the Closing and the execution and delivery of all instruments of
conveyance for the periods set forth in Section 15.7.  Parent, Newco and Seller
acknowledge that each such party is relying solely on its own independent
investigation of the Acquired Assets, in the case of Parent and Newco, and the
Parent Contributed Assets, in the case of Seller, and the representations and
warranties of Seller and Parent expressly set forth in this Agreement and that,
except as expressly set forth in this Agreement, there are no representations 
or warranties of any kind, express or implied, being made by Seller with 
respect to Seller's Indirect Merchant Network Business or the Acquired Assets 
or being made by Parent or Newco with respect to Parent's Indirect Merchant 
Network Business or the Parent Contributed Assets.

     16.12 Public Announcements.  Prior to the Closing, Parent and Seller shall
consult with each other as to the form and substance of any press release or
other public disclosure materially related to this Agreement or any of the
transactions contemplated hereby; provided, that nothing in this Section 16.12
shall be deemed to prohibit any party from making any disclosure which its
counsel deems necessary or advisable in order to satisfy such party's
disclosure obligations imposed by law or regulation or by any regulatory
authority, including the Securities and Exchange Commission and the New York
Stock Exchange.

     16.13 Arbitration.

           (a) Location and Governing Rules.  Except for any dispute or claim
alleging a breach by either party of the provisions of Section 13.9 or with
respect to any default under Seller's or Parent's Real Property Leases any
dispute arising out of or in connection with this Agreement or any of the other
Acquisition Documents, including any question regarding its existence, validity
or termination, shall be referred to and finally resolved by arbitration in
Washington, D.C. under the Rules of Commercial Arbitration (the "Rules") of the
American Arbitration Association (the "AAA"), which Rules are deemed to be
incorporated by reference into this Section 16.13.  Judgment upon the award
rendered by the arbitrators in any such arbitration may be entered in any court
having jurisdiction thereof.  Except as the arbitrators may otherwise award or
assess the expenses of any such arbitration and except as otherwise provided in
this Agreement, each party shall bear its own costs and expenses, including the
expense of its counsel.  The parties agree that service of any notice in the
course of any such arbitration at their respective addresses for notice and in
the manner provided in Section 16.2 of this Agreement shall be valid and
sufficient notice for purposes of such arbitration.

           (b) Selection of Arbitrators.  In any arbitration pursuant to this
Section 16.13 the award shall be rendered by a majority of the members of a
board of arbitration consisting of three members.  One arbitrator shall be
appointed by Seller and one arbitrator shall be appointed by Parent within
sixty (60) days after the commencement of the arbitration proceeding.  The
third arbitrator shall be appointed by mutual agreement of the two arbitrators
selected by Parent and Seller and shall be experienced in corporate contractual
matters relating to transactions of the nature contemplated by this Agreement. 
In the event of the failure of said two arbitrators to agree as to the third
arbitrator within sixty (60) days after the appointment of the last of the two
arbitrators, the third arbitrator shall be appointed by the Washington, D.C.
office of the AAA in accordance with its then-existing rules.  Notwithstanding
the foregoing, in the event that either party shall fail to appoint the
arbitrator it is required to appoint within the specified time period, such
arbitrator and the third arbitrator shall be appointed by the Washington, D.C.
office of the AAA in accordance with its then-existing rules.  For purposes of
this Section 16.13, the commencement of the arbitration proceeding shall be

                               SUBLEASE AGREEMENT


     THIS SUBLEASE AGREEMENT ("Sublease") is made this ___ day of _______, 1996
between [President], a Delaware corporation ("Sublandlord"), and [Ambassador],
a ________________ ("Subtenant").

                                   RECITALS:

     WHEREAS, The Citadel, a Texas limited partnership, as Landlord ("Prime
Landlord") and Sublandlord, as Tenant did enter into a certain Lease (together
with any certain amendments or modifications thereof, the "Prime Lease"), dated
September 1, 1987, for the lease by Sublandlord of certain space (the
"Sublandlord's Premises") more particularly described in the Prime Lease and
located in Prime Landlord's building (the "Building") known as 12115 Lackland
Road, St. Louis, Missouri.  Sublandlord and Subtenant desire to enter into this
Sublease, pursuant to which Subtenant will lease from Sublandlord, and
Sublandlord will lease to Subtenant, a portion of Sublandlord's Premises.

     NOW THEREFORE, for and in consideration of the mutual covenants and
obligations:

     1. SUBLEASED PREMISES.  Sublandlord does hereby lease to Subtenant, and
Subtenant leases and rents from Sublandlord, those certain portions of the ____
floors of the Building consisting of a total of ____ rentable square feet all
as shown outlined on the floor plans collectively attached hereto as Exhibit
A(1)-( ) (the "Subleased Premises").  The Subleased Premises are being leased
by Sublandlord to Subtenant in their condition existing on the date hereof "AS
IS", and Sublandlord shall not be obligated to construct any demising walls or
make any improvements whatsoever with regard to the Subleased Premises.
Subtenant shall be obligated to construct any demising walls necessary on the
Subleased Premises at its own expense and cost.

     2. TERM.  The term of this Sublease shall commence on the date first above
written (the "Commencement Date") and shall end on the last day of the month in
which the second anniversary of the Commencement Date occurs.  Subtenant may
cancel this Sublease at any time upon ninety (90) days' notice to Sublandlord.

     3. Rent.  Subtenant shall pay to Sublandlord a monthly base rent (the
"Base Rent") equal to Subtenant's Share of rent, additional rent and other
obligations of Sublandlord payable to the Prime Landlord under the Prime Lease,
with respect to each month during the term of this Sublease, prorating such
obligations as may be required to the term of this Sublease, and adjusting such
amounts, from time-to-time as they may be adjusted between Prime Landlord and
Sublandlord under the Prime Lease, all without offset, deduction or abatement,
except as otherwise expressly provided for herein.  The Base Rent shall be 
payable by Subtenant to Sublandlord in advance on or before the first day of 
each calendar month during the term of this Sublease with appropriate 
prorations 

                                     - 2 -


<PAGE>   94


for partial months.  The Base Rent, together with any and all other amounts 
from time to time due under this Sublease from Subtenant to Sublandlord, 
is hereinafter referred to collectively as the "Rent".

     If Subtenant fails to pay any installment of the Rent, within five (5)
business days following Subtenant's receipt of notice of Sublandlord's
nonreceipt of such payment to help defray the additional cost to Sublandlord
for processing such late payments, Subtenant shall pay, upon receipt of a
written notice from Sublandlord, to Sublandlord, a late charge of four percent
(4%) of such amount plus interest from and after the due date of such rent
computed at a rate of eighteen percent (18%) per annum for the number of days
from the due date until the unpaid amount plus the late charge has been paid in
full.

     4. RELATIONSHIP TO PRIME LEASE.  This Sublease and Subtenant's rights
hereunder are expressly subject to and subordinate to the Prime Lease.
Subtenant shall not allow any action or omission of Subtenant, its employees,
agents, contractors or affiliates, to place Sublandlord in default or at risk
of being declared in default under the Prime Lease.  Sublandlord shall not
allow any action or omission of Sublandlord, its employees, agents, contractors
or affiliates to place either Sublandlord or Subtenant in default under the
Prime Lease.

     5. USE.  The Subleased Premises shall be used and occupied by Subtenant as
office space for the purpose of conducting computer data operations and for
related uses specifically permitted under the Prime Lease and for no other
purposes.  Subtenant will not occupy or use, nor permit to be occupied or used,
any portion of the Subleased Premises for any business or purpose which is
unlawful in part or in whole or deemed to be disreputable in any manner, or
extra hazardous on account of fire, nor permit anything to be done which is not
in compliance with the foregoing and which will increase the rate of fire
insurance on the Sublandlord's Premises or the Building, and if, by reasons of
acts of Subtenant inconsistent with the foregoing, there shall be any increase
in the rate of insurance on the Sublandlord's Premises or the Building or its
contents created by Subtenant's acts or conduct of business, Subtenant shall
pay the amount of such increase on demand.

     6. REQUIREMENTS OF LAW.  Subtenant at its sole expense shall comply with
all laws, orders and regulations of federal, state, county and municipal
authorities and with any direction of any public officer or officers, pursuant
to law.  Notwithstanding the foregoing, Subtenant shall not be required to
comply with applicable law if such compliance would necessitate improvements or
changes being made to the Subleased Premises and such improvements or changes
are required to be made by all other tenants of the Building, provided the
cause for such improvements or changes is not related to Subtenant's specific
manner and use of the Subleased Premises, in such case, Sublandlord shall make
such improvements and changes to the Subleased Premises or use Sublandlord's 
reasonable efforts to cause the Prime Landlord to do so, provided
that Subtenant shall have no obligation to pay rent at any time that the
Subleased Premises 

 
                                     - 3 -


<PAGE>   95

become substantially unusable for Subtenant's normal operations as a result of
such lack of compliance unless caused by Subtenant.

     7. SERVICES AND REPAIRS.  (a) Under the Prime Lease, Prime Landlord has
agreed to furnish certain services to Sublandlord's Premises.  The times and
days on which such services shall be provided are set forth in such Prime Lease
and any attachment thereto.  Sublandlord shall use reasonable efforts not to
block the provisions of such services to Subtenant and to cause Prime Landlord
to provide those services which Prime Landlord provides to Sublandlord, but
failure to any extent to furnish or any stoppage of these defined services,
resulting from causes beyond control of Sublandlord or from any cause not the
fault of Sublandlord, shall not render Sublandlord liable in any respect for
damages to person, property or business, nor be construed as an eviction of
Subtenant or work an abatement of rent, nor relieve Subtenant from fulfillment
of any covenant or agreement hereof except payment of Rent if the Subleased
Premises become substantially unusable for Subtenant's normal business
operations as a result of such lack of service and as a result thereof
Sublandlord is relieved of its obligation to pay Rent under the Prime Lease.
Notwithstanding anything to the contrary herein, Subtenant shall be entitled to
a pro rata share of any rent abatement received by Sublandlord from Prime
Landlord in accordance with Paragraph 5(a) of the Prime Lease.  Subtenant shall
pay to Sublandlord within twenty (20) days such charges as Sublandlord may
reasonably prescribe based on a reasonable portion of Prime Landlord's charges
and Sublandlord's costs for any electric service requested by Subtenant and
supplied by Sublandlord or Prime Landlord, for heat or air conditioning service
for times other than as set forth in the Prime Lease or for computers and other
electrical equipment or other electric service deemed by Prime Landlord not to
be standard.

     (b) Under Paragraph 5(b) of the Prime Lease, Prime Landlord has agreed to
keep and maintain in good condition the structural portion of the Building and
the roof, floors (except carpeting), elevator pits and load bearing walls
except in case of any damage caused by any act or negligence of Sublandlord,
its employees, agents, invitees, subtenants, assignees, licensees or
contractors, and to be responsible for repairing any damages (structural or
otherwise) caused by any act or negligence of Prime Landlord, its employees,
agents or contractors.  Sublandlord shall use reasonable efforts to cause Prime
Landlord to provide above defined services to Subtenant.  Provided Sublandlord
has used reasonable efforts to cause Prime Landlord to provide such services,
Sublandlord shall have no responsibility for the foregoing obligations of Prime
Landlord and shall have no liability if such services have not been provided,
but Subtenant shall have no obligation to pay Rent at any time that the
Subleased Premises become substantially unusable for Subtenant's normal
business operations as a result of such lack of repair provided that during
such period Sublandlord is relieved of its obligation to pay Rent under the
Prime Lease.

     8. SUBTENANT'S REPAIRS AND ALTERATIONS.  (a) Subtenant shall not in any
manner deface, damage or injure the Subleased Premises or the Building, and
shall pay the cost of repairing any damage or injury done to the Subleased
Premises or the 

                                     - 4 -


<PAGE>   96


Building or any part thereof by Subtenant or Subtenant's agents, employees,
contractors, customers or invited guests.  Subtenant shall during the term of
this Sublease take good care of the Subleased Premises and keep them free from
waste of any kind.  Subtenant shall keep the Subleased Premises in good
condition and make all necessary repairs, subject to Sublandlord's and Prime
Landlord's obligations under Paragraph 7(b) hereof.  At the expiration or
earlier termination of this Sublease, Subtenant shall deliver to Sublandlord the
Subleased Premises with all improvements thereon in good repair and condition,
reasonable wear and tear, casualty and condemnation excepted.  Subtenant shall
not make or allow to be made any alterations, additions or improvements in or to
the Subleased Premises without the prior written consent of Sublandlord which
consent unless the consent of the Prime Landlord is required, as hereinafter
contemplated, shall not be unreasonably withheld, conditioned or delayed if the
aggregate cost of restoration of all changes and alterations to be made by such
tenant under this Sublease shall not exceed $50,000.00 or if the aggregate cost
of restoration shall exceed such amount, such consent shall not be unreasonably
withheld, condition or delayed other than the agreement of Subtenant to pay such
excess amount of restoration cost may be imposed as a condition to such
approval.  Any such work shall be done at Subtenant's sole expense and without
the creation of mechanics' or materialmen's liens.  If such alterations,
additions or improvements would require Prime Landlord's written consent prior
to their performance by Sublandlord under the Prime Lease, then Sublandlord may
at its sole discretion withhold its consent to Subtenant's performance of such
alterations, additions or improvements, until receipt of Prime Landlord's
written consent, provided, however that Sublandlord shall use reasonable and
timely efforts to obtain Prime Landlord's written consent for such alterations,
additions or improvements.  Notwithstanding the foregoing, for structural
alterations, additions, or improvements, Sublandlord shall respond promptly to
Subtenant's request and may attach reasonable conditions to its consent
(including, but not limited to, removal of the alteration, addition or
improvement and restoration to its original state at termination or expiration
of the Sublease).  If a lien is placed against the Sublandlord's Premises or the
Building by reason of action by Subtenant, Subtenant shall post a proper bond in
or deposit with a title company or other escrow agent, an amount sufficient to
cover all amounts due under said lien within twenty (20) days.  At the
termination or expiration of this Sublease, unless Subtenant is to remove
structural alterations, additions or improvements erected by Subtenant and
restore the Subleased Premises to their original condition as a prior condition
to Sublandlord's consent above, such alterations, additions and improvements
shall be delivered to Sublandlord with the Subleased Premises.  All furniture
and moveable trade fixtures installed by Subtenant may be removed by Subtenant
at the termination of this Sublease if Subtenant so elects, and shall be removed
if Sublandlord or Prime Landlord so elects.  All such removals and restoration
shall be accomplished in a good workerlike manner so as not to damage the
Building.

     9. ASSIGNMENT AND SUBLETTING.  Subtenant may not assign this Sublease, nor
allow same to be assigned by operation of law or otherwise, nor sublet the
Subleased Premises or any part thereof without the prior written consent of
Sublandlord which consent shall be at the absolute discretion of Sublandlord
and subject to any 


                                     - 5 -


<PAGE>   97

condition Sublandlord elects to impose and without the prior written consent of
Prime Landlord which consent shall be subject to Prime Landlord's rights under
the Prime Lease, provided that if Subtenant wishes to sublet a reasonably
contiguous portion of the Subleased Premises of more than 5,000 square feet so
that following such subletting the unsublet Subleased Premises shall constitute
at least 5,000 square feet, Sublandlord will not unreasonably withhold, delay or
condition its consent to such subletting provided that Subtenant has given
Sublandlord not less than twenty (20) days' notice of such subletting, during
which time Sublandlord may elect, by notice to Subtenant to cancel this Sublease
with respect to the space proposed to be sublet, and in such event, the Rent
shall thereafter be adjusted based on the portion of the Subleased Premises then
remaining.

     10. MAINTENANCE.  Subtenant, at its sole expense, shall maintain the
Subleased Premises in a clean and healthful condition, and subject to Paragraph
6 comply with all laws, ordinances, orders, rules and regulations (state,
federal, municipal, and other agencies or bodies having any jurisdiction
thereof) with reference to use, condition, or occupancy of the Subleased
Premises.  Sublandlord shall maintain those portions of Sublandlord's Premises
outside the Subleased Premises in a clean and healthful condition and subject
to Paragraph 6 comply with all laws, ordinances, orders, rules and regulations
(state, federal, municipal, and other agencies or bodies have jurisdiction
thereof) with reference to use, condition, or occupancy of said portions of the
Sublandlord's Premises and the Building in accordance with the Prime Lease.

     11. INDEMNITY.  Neither party shall be liable for, and the other party
will indemnify and save harmless said party from, any and all fines, suits,
claims, costs, expenses, demands, and actions of any kind (including reasonable
attorney's fees) by reason of any negligence, misconduct, or any breach,
violation, or non-performance of any covenant hereof on the part of the other
party or its agents, employees, and/or invitees.  Neither party shall be liable
or responsible for any loss or damage to any property or person occasioned by
theft, fire, act of God, public enemy, injunction, riot, strike, insurrection,
war, court order, requisition or order of governmental body or authority or
other matter beyond such party's reasonable control, or for any damage or
inconvenience which may arise through repair or alteration of any part of the
Building, or failure to make repairs, or from any cause whatever except such
party's negligent act or omission, or willful misconduct or intentional breach
of this Sublease.  This Paragraph shall not preclude one party from seeking
reimbursement from the other for work or monies expended which is the
responsibility of the other party.  This Paragraph shall survive termination or
expiration of this Sublease.

     12. RULES AND REGULATIONS.  Subtenant and Subtenant's agents, employees,
and invitees, shall comply fully with all requirements of the Rules and
Regulations ("Rules and Regulations") of the Building, if any.  Subtenant
acknowledges that if pursuant to the Prime Lease, Prime Landlord may change
such Rules and Regulations or amend them from time to time, then upon receipt
thereof, Sublandlord shall deliver copies of all changes, and amendments
thereto, to Subtenant, and Subtenant shall comply therewith.



                                     - 6 -


<PAGE>   98


     13. INSPECTION.  Sublandlord and Prime Landlord, or their officers,
agents, and representatives, may enter into and upon any and all parts of the
Subleased Premises upon one (1) day's notice at all reasonable hours to inspect
same or clean or make repairs or alterations or additions as Sublandlord shall
reasonably deem necessary or as Prime Landlord may be entitled to under the
Prime Lease, except that in cases of emergency the right to enter shall not be
subject to any notice or time restrictions.

     14. CONDUCT OF BUSINESS.  Subtenant shall conduct its business, and
control its agents, employees, contractors, customers and invited guests in
such a manner as not to unreasonably interfere with, annoy or disturb other
tenants or Sublandlord or Prime Landlord in the management of the Building.
Sublandlord will conduct its business, and control its agents, employees,
contractors, customers and invited guests in such a manner as not to
unreasonably interfere with, annoy or disturb Subtenant's normal business
activities.

     15. CONDEMNATION.  If the Subleased Premises shall be taken or condemned
in whole or substantial part for public purposes, this Sublease shall
terminate.

     In the event of a partial condemnation, either Sublandlord or Subtenant
may elect, in its sole discretion, by notice to the other to terminate this
Sublease provided that if this Sublease shall not terminate, there shall be an
abatement of the Rent, on a square footage basis, to the extent and degree that
the Subleased Premises may no longer be utilized by Subtenant as a result of
the Condemnation.

     If any part of the Subleased Premises shall be so taken and this Sublease
shall not be terminated under the provisions of this Paragraph, then
Sublandlord shall use reasonable efforts to cause Prime Landlord to perform
restoration, at Prime Landlord's own cost and expense, of the remaining portion
of the Subleased Premises to the extent necessary to render it reasonably
suitable for the purposes for which it was leased.  Sublandlord shall have no
responsibility to perform such restoration or liability in connection thereto
but, to the extent that Sublandlord is relieved of its obligation to pay rent
pursuant to the Prime Lease, Subtenant shall have no obligation to pay Rent at
any time the Subleased Premises become substantially unusable for Subtenant's
normal business operations as a result of such condemnation.

     16. FIRE & OTHER CASUALTY.  If the Building should be totally or partially
destroyed by fire, tornado or other casualty, either Sublandlord or Subtenant
may, in its sole discretion, terminate this Sublease by notice to the other,
given within ninety (90) days of such casualty or, if Prime Landlord 
terminates the Prime Lease pursuant thereto, this Sublease shall terminate.  
If this Sublease is not so terminated, Subtenant acknowledges that Prime 
Landlord is required under the Prime Lease to rebuild and repair Sublandlord's
Premises.  Sublandlord shall have no responsibility for such rebuilding and 
repair but, to the extent that Sublandlord is relieved of its obligation to 
pay rent pursuant to the Prime Lease, Subtenant shall have no obligation to 
pay Rent at any time the 



                                     - 7 -


<PAGE>   99

Subleased Premises become substantially unusable for Subtenant's normal business
operations as a result of such casualty.

     Sublandlord and Subtenant shall each look first to any insurance in its
favor before making any claim against the other party for recovery for loss or
damage resulting from fire or other casualty and to the extent that such
insurance is in force and collectible and to the extent permitted by law.
Sublandlord and Subtenant each hereby releases and waives all right of recovery
against the other or any one claiming through or under each of them by way of
subrogation or otherwise.  The foregoing release and waiver shall be in force
only if both releasors' insurance policies contain a clause providing for such
a release or waiver shall not invalidate such insurance.  If such coverage is
available for a reasonable additional premium each party shall pay such
additional premium under its policy.  Subtenant acknowledges that Sublandlord
will not carry insurance on Subtenant's furniture and/or furnishings or any
fixtures or equipment improvements or appurtenances removable by Subtenant and
agrees that Sublandlord will not be obligated to repair any damage or replace
the same.  Throughout the term of this Sublease, Sublandlord shall carry
insurance on the leasehold improvements within the Subleased Premises to the
extent of the coverage as of the date of this Sublease.

     Subtenant shall carry and maintain (a) public liability insurance in the
amount of at least $1,000,000 and (b) property damage insurance in the amount
of at least $500,000.

     17. HOLDING OVER.  Should Subtenant, or any of its successors in interest,
hold over the Subleased Premises, or any part thereof, after the expiration of
the term of this Sublease or after the termination of this Sublease by
Sublandlord as a result of a default by Subtenant, unless otherwise agreed in
writing, such holding over shall constitute and be construed as a tenancy at
will only, at 150% of the Base Rent paid for the last month of the term of this
Sublease for that portion of the Subleased Premises held over.  If the holding
over continues for more than 180 days after notice given by Sublandlord to
Subtenant to vacate such space held over, the Base Rent shall be two (2) times
the above described Base Rent paid for that portion of the Subleased Premises
held over.  The inclusion of the preceding sentence shall not be construed as
Sublandlord's consent for Subtenant to hold over, nor require any notice from
Sublandlord to terminate Subtenant's tenancy, except as specifically provided
for herein, it being agreed that unless otherwise specifically agreed,
Sublandlord shall be entitled to immediate possession of the Subleased Premises
upon any termination of this Sublease.  Furthermore, in the event that such
holding over shall result in additional obligations or liability on the part of

Sublandlord may, without prejudice to any other remedy which it may have
for possession or arrearages in rent, enter upon and take possession and expel
or remove Subtenant and any other person who may be occupying the  Subleased
Premises or any part thereof, by force if necessary, without being liable for
prosecution or any claim of damages thereof; and Subtenant agrees to pay to
Sublandlord or demand the amount of all loss and damage which Sublandlord may
suffer by reason of such termination, whether through inability to relet the
Subleased Premises or satisfactory terms or otherwise, said loss and damage to
include all damages to which Sublandlord is entitled at law arising from
Subtenant's breach and the termination of this Sublease.

     (b) Enter upon the Subleased Premises by reasonable force if necessary
without being liable for prosecution or any claim for damages therefor, and do
whatever Subtenant is obligated to do under the terms of this Sublease; and
Subtenant agrees to reimburse Sublandlord on demand for any reasonable expenses
which Sublandlord may incur in thus effecting compliance with Subtenant's
obligations under this Sublease, and Subtenant further agrees that Sublandlord
shall not be liable for any damages resulting to the Subtenant for such action.

     Pursuit any of the foregoing remedies shall not preclude pursuit of any of
the other remedies herein provided or any other remedies provided by law, nor
shall pursuit of any remedy herein provided constitute a forfeiture or waiver
of any rent due to Sublandlord hereunder or of any damages occurring to
Sublandlord by reason of the violation of any of the terms, provisions and
covenants herein contained.  Sublandlord's acceptance of rent following an
event of default hereunder shall not be construed as Sublandlord's waiver of
such event of default.  No waiver by Sublandlord of any violation or breach of
any of the terms, provisions and covenants herein contained shall be deemed or
construed to constitute a waiver of any other violation or breach of any of the
terms, provisions, and covenants herein contained.  Forbearance by Sublandlord
to enforce one or more of the remedies herein provided upon an event of default
shall not be deemed or construed to constitute a waiver of such default.  None
of the foregoing shall diminish or eliminate Sublandlord's obligation to
mitigate damages to the extent such obligation exists under the laws of the
state in which the Subleased Premises are located.

     21. SURRENDER OF PREMISES.  No act or thing done by Sublandlord or its
agents during the term hereby granted shall be deemed an acceptance of a
surrender of the Subleased Premises, and no agreement to accept a surrender of
the Subleased Premises shall be valid unless the same be made in writing and
subscribed by Sublandlord.

     22. ATTORNEY'S FEES.  If it should be necessary or proper for either
Sublandlord or Subtenant to bring any action under this  Sublease to recover
any amount payable hereunder, or for the enforcement of any of Sublandlord's or
Subtenant's rights hereunder, the party prevailing completely on all issues
shall have the right to recover in any such case a reasonable attorney's fee.

     23. RECEIPTS FROM ASSIGNEE OR SUBTENANT.  The receipt by Sublandlord or
Prime Landlord of rent from any assignee, subtenant or occupant of the
Subleased Premises shall not be deemed a waiver of the covenant in this
Sublease contained against assignment and subletting or an acceptance of the
assignee, subtenant or occupant as tenant or a release of Subtenant from the
further observance or performance by Subtenant of the covenants in this
Sublease contained, on the part of Subtenant to be observed and performed.  No
provision of this Sublease shall be deemed to have been waived by the parties
unless such waiver be in writing signed by said party.

     24. QUIET ENJOYMENT; SUBLANDLORD'S REPRESENTATIONS.  Subtenant, upon the
payment of the rentals and performance of the covenants on Subtenant's part to
be performed hereunder, shall and may peaceably and quietly have, hold and
enjoy the Subleased Premises during the term hereof and any extensions thereof,
free from interference or disturbance from Sublandlord, but subject to the
terms and conditions of this Sublease and the Prime Lease.  Notwithstanding
anything to the contrary, Sublandlord shall not be liable for any interference
or disturbance from other tenants or third persons, nor such Subtenant be
released from any of the obligations of this Sublease because of such
interference or disturbance, unless such results from a third party claiming
through Sublandlord or Sublandlord fails to enforce diligently its rights to
cause such interference or disturbance to cease; provided that, to the extent
that Sublandlord is relieved of its obligation to pay rent pursuant to the
Prime Lease, Subtenant shall not be obligated to pay Rent at any time the
Subleased Premises become substantially unusable for Subtenant's normal
business operations as a result of any such disturbance of Subtenant's
possession of the Subleased Premises.

     If Sublandlord shall fail to comply with any material term, provision, or
covenant of this Sublease, Subtenant may give notice to Sublandlord to correct
such default.  Sublandlord shall have the right to correct or remedy such
default before Subtenant may take any action under this Sublease by reason of
such default.  If such default shall continue for forty-five (45) days after
such written notice, or such further period as may be reasonably required to
cure such default if it is of such a nature that it cannot reasonably be cured
within such forty-five (45) day period, the Rent shall be abated on a
square footage basis during the period the Subleased Premises or a part thereof
is unfit for occupancy.

     Sublandlord represents and warrants to Subtenant that:

     (a) Sublandlord has heretofore provided Subtenant with a copy of the Prime
Lease and all amendments and modifications thereof;

     (b) there has been no assignment of  Sublandlord's interest therein or
sublease of the Subleased Premises, other than pursuant to this Sublease;

which is required by the Prime Lease.

the services required for the transition of the Business from MasterCard to the
Company are important to a smooth transition.  Therefore, to the extent that
any services required by the Company in connection with the transition
associated with the Excluded Contracts or Excluded Assets or otherwise required
to operate the Business in substantially the same manner as previously
conducted by MasterCard are not included in the Initial Services, the Company
may request such services hereunder, and MasterCard will make a
reasonable effort to perform such transition services (the "Supplemental
Services") (the Initial 


                                     - 2 -
<PAGE>   111

Services and the Supplemental Services, if any, are hereinafter collectively
referred to as the "Services").


                                   ARTICLE 3
                         ADEQUATE STAFF AND FACILITIES

     MasterCard shall use commercially reasonable efforts, during the Term of
this Agreement, to maintain adequate staff, support services and facilities as
may be necessary to perform its responsibilities under this Agreement, in
keeping with the standards of accuracy and promptness observed by MasterCard in
providing the Services with respect to its own business.


                                   ARTICLE 4
                            PRICE AND PAYMENT TERMS

     4.1 PRICE FOR SERVICES.  The price to be paid by the Company for each
Initial Service (the "Initial Service Cost") shall initially be as set forth on
Schedule 2.1, and thereafter as the parties shall mutually agree.  With respect
to any Supplemental Services provided pursuant to Section 2.3 of this
Agreement, the cost (the "Supplemental Service Cost") shall be the lesser of:
(a) MasterCard's actual direct cost of providing such Service (provided that
such formula shall not include any amounts for depreciation, amortization,
overhead, support services, profit, cost of capital, or other indirect costs);
or (b) if MasterCard were to continue to own the Business after Closing, the
amount that MasterCard would allocate as an intercompany charge to the Business
division for such Service, applying the same formula for computing such
intercompany charge that MasterCard has used consistent with prior practices as
reflected in MasterCard's financial statements referred to in the Purchase
Agreement.

     4.2 PAYMENT.  The Initial Service Cost and the Supplemental Service Cost,
if any (collectively, "Service Cost"), will be paid as follows:

     (a) Monthly Invoices.  After the end of each month during the Term,
MasterCard will provide to the Company an invoice for each Service showing the
Service Cost therefor for such month just ended.  Upon request, MasterCard will
provide the Company with such supporting documentation as may be reasonably
requested by the Company.  Subject to the procedures for dispute set forth
below, the Company shall pay the amount shown on each such invoice within ten
(10) days after receipt thereof by means of a company check.  The Service Cost
for any Service that is provided for only part of a month shall be
appropriately prorated.

     (b) Disputes.  In the event that the Company disagrees with any invoice
submitted by MasterCard as required by subsection (a) immediately above, the
Company shall promptly notify MasterCard of such disagreement following the
Company's 


                                    - 3 -

<PAGE>   112

determination of the disagreement.  The parties shall then cooperate
to resolve the dispute, with MasterCard providing the Company with such
supporting documentation relating to the calculation of the Service Cost as the
Company may reasonably request.  If the parties do not resolve the dispute
within twenty (20) days after MasterCard's receipt of the Company's dispute
notice, either party can submit the dispute to arbitration, in accordance with
Article 6 hereof.

     (c) Other Documents.  MasterCard shall provide to the Company upon
reasonable request any reports or summaries relating to the Service Costs,
which the Company may need for preparing financial statements, tax returns or
otherwise.

     4.3 INTEREST ON LATE PAYMENTS.  Any monthly payment of the Service Cost
that is not paid on or before the tenth (10th) day of the calendar month in
which it is due shall bear interest from such due date until the date paid at
the lesser of (a) an annual simple interest rate equal to Prime Rate plus 2%,
or (b) the maximum amount permitted by Applicable Law.

     4.4 TAXES.  Any transaction, excise, sales or similar Tax imposed on or
measured by the rendering of a Service shall be the responsibility of the
Company.  All other Taxes associated with a Service shall be paid by
MasterCard; provided, however, that each party shall be responsible for its own
income Taxes.


                                   ARTICLE 5
                              TERM AND TERMINATION

     5.1 TERM.  This Agreement shall commence on the Closing Date and, unless
sooner terminated in accordance with Section 5.2 below, shall continue in
effect for a term (the "Term") expiring on the third (3rd) anniversary of the
Closing Date.

     5.2 TERMINATION.

     (a) By the Company.  The Company shall be entitled to terminate this
Agreement at any time, in whole or in part with respect to any or all of the
Services, by providing thirty (30) days' written notice to MasterCard.

     (b) By MasterCard.  MasterCard shall not be entitled to terminate this
Agreement, except in the event that the Company is in material breach of this
Agreement and such breach remains uncured for more than 30 days after notice
thereof has been provided by MasterCard to the Company; provided, that if such
breach is not capable of being cured within 30 days of such notice, and if the
Company, upon receipt of such notice, promptly commences and diligently pursues
the cure to completion as soon as reasonably possible, then such 30-day period
shall be extended for the period of time which is reasonably necessary to cure
the breach.

     5.3 EFFECT OF TERMINATION.  Upon termination of this Agreement, all rights
and obligations of each party hereunder shall cease as of the date of the
termination, and any amounts owed by either party pursuant to this Agreement
shall be paid in full.  In addition, upon any termination of this Agreement,
MasterCard shall promptly return to the Company any property of the Company
used in connection with the provision of the Services.  Notwithstanding the
foregoing, the termination of this Agreement pursuant to any of the provisions
hereof shall be without prejudice to any rights, or diminution of any
obligation or liability of either party, that may have accrued prior to the
effective date of such termination.  In addition, the provisions of Article 7
and Section 8.1 shall survive the termination of this Agreement.


                                   ARTICLE 6
                          DISPUTE RESOLUTION PROCEDURE

     Any controversy or claim arising out of or relating to this Agreement, the
breach hereof, or coverage of this arbitration provision, which is not settled
by MasterCard and the Company, shall be settled by arbitration in accordance
with the procedures therefor set forth in the Purchase Agreement.


                                   ARTICLE 7
                                INDEMNIFICATION

     7.1 LIMITATION OF LIABILITY.  Except to the extent provided in Sections
7.2 and 7.3 hereof, nothing in this Agreement is intended to impose upon
MasterCard, and MasterCard does not intend to assume in this Agreement, any of
the risks associated with operation of the Business, including, without
limitation, product or service quality and liability therefor, except to the
extent MasterCard is providing the services associated with such product or
service quality and then subject to the provisions in Section 7.2.  Except as
provided elsewhere in this Agreement, neither party shall have any liability to
the other party for any costs, damages, expenses, liabilities or losses
incurred by such other party in connection with this Agreement or the
performance of either party's obligations hereunder, whether such claim of
liability arises in an action at law or in equity, and whether such claim
sounds in contract or tort or otherwise.

     7.2 INDEMNIFICATION BY MASTERCARD.  Subject to the provisions of Section
7.4, MasterCard hereby agrees to indemnify and hold harmless the Company, its
Affiliates, and their respective directors, officers, employees, successors and
assigns (collectively, "Agents"), from and against any and all claims, demands,
causes of action and lawsuits ("Claims") (including Claims against the Company,
its Affiliates or their respective Agents by MasterCard, its Affiliates or their
respective Agents, or any third party), and liabilities, penalties, judgments,
losses, injuries, damages, costs, fees and expenses (including, without
limitation, costs of defense, settlement, and reasonable attorneys' fees and
expenses relating to matters or actions arising under this Agreement)
("Damages"),

                                     - 5 -
<PAGE>   114

suffered or incurred by the Company, its Affiliates or their respective Agents,
arising out of or resulting from any material breach of this Agreement by
MasterCard or the fraud, negligence or willful misconduct of MasterCard in
connection with the performance of its obligations under this Agreement.

     7.3 INDEMNIFICATION BY THE COMPANY.  Subject to the provisions of Section
7.4, the Company hereby agrees to indemnify and hold harmless MasterCard, its
Affiliates, and their respective Agents from and against any and all Claims
(including Claims against MasterCard, its Affiliates or their respective Agents
by the Company, its Affiliates or their respective Agents, or any third party)
and Damages suffered or incurred by MasterCard, its Affiliates or their
respective Agents, arising out of any material breach of this Agreement by the
Company or resulting from the provision of Services under this Agreement, other
than any and all Claims or Damages arising out of or resulting from any
material breach of this Agreement by MasterCard or the fraud, negligence or
willful misconduct of MasterCard in connection with the performance of its
obligations under this Agreement.

     7.4 INDEMNIFICATION PROCEDURES.

     (a) In the event that, from and after the Closing Date, a third party
asserts a Claim against MasterCard, its Affiliates or their respective Agents
(the "MasterCard Indemnitees"), or the Company, its Affiliates or their
respective Agents (the "Company Indemnitees"), with respect to any matter to
which the indemnities set forth in this Article 7 apply (a "Third Party Claim"),
the MasterCard Indemnitee or the Company Indemnitee, as the case may be, against
whom the Third Party Claim is asserted (the "Indemnified Party") shall give the
Company or MasterCard, as the case may be (the "Indemnifying Party"), prompt
notice of such Third Party Claim.  The Indemnifying Party, at its own expense,
shall have the right to undertake the defense of such Third Party Claim by
retaining counsel of its own choosing (after giving notice of such retention of
counsel to the Indemnified Party), which counsel shall be reasonably
satisfactory to the Indemnified Party.  If an expense or cost is found to be
associated with an Indemnified Party's failure to give timely notice to the
Indemnifying Party, the Indemnified Party shall pay such expense or cost;
provided, that in agreeing to pay such expense or cost the Indemnified Party
shall not be deemed in any way to have waived its right to indemnification
hereunder, net of any such expense or cost.  In the event that a party from whom
indemnification is sought chooses not to undertake the defense of any Third
Party Claim asserted (and hereby agrees to provide written notice of such
decision to the other party), and the party seeking indemnification does
undertake the defense of such Third Party Claim, and the party from whom
indemnification is sought is subsequently held to be liable for such Third Party
Claim, the party from whom indemnification is sought agrees that it will fully
indemnify the party seeking indemnification for the Damages it may owe to such
party in connection with such Third Party Claim, including, without limitation,
attorneys fees and other expenses related to the defense of such Third Party
Claim which are incurred by the party seeking indemnification.

                                     - 6 -
<PAGE>   115


     (b) Notwithstanding anything to the contrary in this Section 7.4, if there
is a reasonable probability in the Indemnified Party's judgment that a Third
Party Claim may materially and adversely affect the Indemnified Party other
than as a result of money damages ("Non-Monetary Claims"), the Indemnified
Party will have the right to defend or co-defend (in each case, at the
Indemnified Party's expense), compromise or settle such Non-Monetary Claim to
the extent it relates to the Indemnified Party or the Indemnified Party's
business; provided that if the Indemnifying Party does not consent in writing
to any such settlement or compromise (which consent shall not be unreasonably
withheld, conditioned or delayed) the settlement or compromise shall be at the
Indemnified Party's expense.

     (c) The Indemnifying Party will provide each Indemnified Party with access
to all records and documents of the Indemnifying Party relating to any Third
Party Claim.  The Indemnified Party will provide the Indemnifying Party with
access to all records and documents of the Indemnified Party relating to any
Third Party Claim.

     (d) Notwithstanding any other provision of this Agreement, the liability
of an Indemnifying Party under this Agreement shall be limited to the direct
damages (which the Company and MasterCard agree shall also include lost profits
only with respect to any Claim arising out of or resulting from any material
breach of this Agreement or fraud or willful misconduct in connection with the
performance of this Agreement) of the Indemnified Party and shall not otherwise
include incidental, consequential, indirect, special, punitive, exemplary or
other similar damages awarded as such directly to such party, other than
compensatory damages.  In calculating any amount of actual damages to be paid
by MasterCard or the Company as set forth in this Article 7, the amount of such
damages shall be reduced by all net tax benefits and other reimbursements
credited to or received by the other party, relating to such damages.


                                   ARTICLE 8
                                 MISCELLANEOUS

     8.1 CONFIDENTIALITY.

     (a) Each party agrees not to use, copy or disclose the trade secrets and
confidential information of the other party, except as permitted by this
Agreement.  Each party shall treat the other's confidential and secret
information with at least that degree of care it uses with respect to its own
such information.  Each party will give access to the other party's confidential
information only to such of its personnel and representatives as have a need to
such access for the purpose of providing the services hereunder, and to no other
person whatsoever.  The requirements herein contained with respect to
non-disclosure and non-use and protection of each party's trade secrets and
confidential information shall permanently survive termination of any other
provisions of this Agreement.  If either party is ordered by a court or
Governmental Authority of competent jurisdiction to disclose trade secrets or
confidential information, or if it is served with or 


                                    - 7 -

<PAGE>   116

otherwise becomes aware of a motion or similar request that such an order be
issued, then such party will not be liable to the other party for disclosure of
trade secrets or confidential information required by such order if the
disclosing party complies with the following requirements:  (1) if an already
issued order calls for immediate disclosure, then the disclosing party promptly
moves for or otherwise requests a stay of such order to permit the other party
to respond; (2) the disclosing party promptly notifies the other party of the
motion or order; and (3) the disclosing party does not oppose a motion or
similar request by the other party for an order protecting the confidentiality
of the trade secrets and confidential information including joining or agreeing
to (or non-opposition to) a motion for leave to intervene by such other party.

     (b) The term "trade secrets" means information related to a party (1)
which derives economic value, actual or potential, from not being generally
known to or readily ascertainable by other persons who can obtain economic
value from its disclosure or use, and (2) which is the subject of efforts by
said party that are reasonable under the circumstances to maintain its secrecy.

     (c) The term "confidential information" means information that is
confidential to the business of a party and is not a trade secret; provided,
however, that confidential information does not include information which is or
becomes generally known to the public without any breach by a party of its
duties to the other party.  Assuming that the foregoing criteria are met,
confidential information also includes information which has been disclosed to
a party and which such party is obligated to treat as confidential.

     8.2 SUCCESSORS AND ASSIGNS.  This Agreement may not be assigned by any
party hereto without the prior written consent of the other party, which
consent shall not be unreasonably withheld, conditioned or delayed.
Notwithstanding the foregoing, the Company may assign or otherwise transfer all
of its rights and/or obligations hereunder to any Affiliate of the Company or
to any entity or entities, or any assignee of such entity or entities, which
acquires, by purchase, operation or law or otherwise, all or a substantial
portion of the assets of the Business.

     8.3 GOVERNING LAW.  The construction, validity and enforceability of this
Agreement shall be governed by the internal laws of the State of Georgia,
without regard to the conflict of laws principles thereof.

     8.4 NOTICES.

     8.5 NO WAIVER.  The failure of either party at any time to require
performance by the other party of any provision of this Agreement shall in no
way affect the right of such party to require performance of that provision.
Any waiver by either party of any breach of any provision of this Agreement
shall not be construed as a waiver of any continuing or succeeding breach of
such provision, a waiver of the provision itself or a waiver of any right under
this Agreement.

     8.6 SEVERABILITY.  All provisions of this Agreement are severable and any
provision which may be prohibited by law shall be ineffective to the extent of
such prohibition without invalidating the remaining provisions of this
Agreement; provided, that if the provisions of Article 7 or any part thereof

<PAGE>   119

on behalf of the other party with respect to the subject matter hereof, nor on
any course of dealings or custom and usage in the trade, except as such promise,
inducement or representation may be expressly set forth herein.  No modification
or amendment to this Agreement will be valid or binding unless reduced to
writing and duly executed by the party or parties to be bound thereby.

     8.8 INDEPENDENT CONTRACTOR STATUS.  MasterCard shall be deemed to be an
independent contractor to the Company.  Nothing contained in this Agreement
shall create or be deemed to create the relationship of employer and employee,
and no party to this Agreement shall, by reason hereof, be deemed to be a
partner or a joint venturer of any other party hereto in the conduct of their
respective businesses and/or the conduct of the activities contemplated by this
Agreement.  Except as specifically and explicitly provided in this Agreement,
and subject to and in accordance with the provisions hereof, no party to this
Agreement is now, shall become, or shall be deemed to be an agent or
representative of any other party hereto with respect to the subject matter
hereof.  Except as herein explicitly and specifically provided, neither party
shall have any authority or authorization, of any nature whatsoever, to speak

matter hereof.

     8.9 BINDING EFFECTS; BENEFITS.  This Agreement will be binding upon and

     8.10 SECTION HEADINGS.  The section headings contained in this Agreement
are for reference purposes only and shall not in any way control the meaning or

     8.11 FORCE MAJEURE.  MasterCard shall be excused from performing the

any period it is prevented from performing the Services, in whole or in part,
as a result of delays caused by an act of God, war, civil disturbance, court
order, labor dispute, or other cause beyond its reasonable control, including
failures or fluctuations in electrical power, heat, light, or
telecommunications, and such nonperformance shall not be a default under, or
grounds for termination of, this Agreement.

     8.12 INTERPRETATIONS.  Neither this Agreement nor any uncertainty or
ambiguity herein shall be construed or resolved against either party, whether
under any rule of construction or otherwise.  Neither party hereto shall be
considered the draftsman.  On the contrary, this Agreement has been reviewed,
negotiated and accepted by all parties and their lawyers and shall be construed
and interpreted according to the ordinary meaning of the words used so as to
fairly accomplish the purposes and intentions of all parties hereto.

Contribution Agreement dated as of February 22, 1996 (the "Purchase

     WHEREAS, the Purchase Agreement provides that it shall be a condition to
the consummation of the transaction provided for therein that the Company and
NDC enter into this Agreement;

     NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants contained herein, the Company and NDC agree as follows:

                             TERMS AND CONDITIONS

      1.     NEWCO SERVICES: According to the terms of this Agreement, the
      Company will furnish NDC and its Affiliates with the data processing
      services described in Exhibits A-1 through A-3, Service Description,
      attached hereto and incorporated herein by reference. Additional requested
      Services, if available, will be furnished to NDC under the general terms
      and conditions of this Agreement and in accordance with pricing as set
      forth in Paragraph 2, below. Any such additional Services will be as
      described in additional Exhibits A to this Agreement, each of which shall
      be signed by both parties hereto.  Any Exhibit A may contain terms
      different than those contained in this Agreement, and in such event the
      terms of each such Exhibit A shall control with respect to the Services
      described in such Exhibit A.

      2.     CHARGES: Charges for the Services shall be as set forth in
      Exhibits B-1 through B-3, Service Pricing Schedules.  Pricing for
      additional Services shall be as set forth in additional Exhibits B
      to this Agreement, each of which shall be signed by both parties
      hereto.  The amount of usage of Services to be paid for by NDC
      shall be that amount recorded by the Company's computer system.
      Charges for requested Services for which there is no published
      rate shall, in the absence of prior written agreement, be at a
      reasonable rate as determined by the Company.  In addition, NDC
      will be charged an amount equal to any taxes, however designated,
      levied or based on any of the above referred to charges or
      Services, including State 


<PAGE>   124

      and local taxes paid or payable by the Company, excluding any 
      federal, State or local taxes based on the Company's net income.

      The Company will bill NDC monthly for all charges incurred by NDC,
      including any authorized charges incurred by the Company on NDC's behalf
      for NDC's use of the Services as provided for in this Agreement.  NDC
      agrees to pay the Company upon receipt of each monthly invoice, and
      agrees further to pay a one percent (1%) per month service charge on all
      invoices that are not paid within thirty (30) days following such
      receipt.  All payments shall be made in United States Dollars.  In the
      event that any invoice is not timely paid as provided herein, the Company
      may, in addition to any other right or remedy which it may have under
      this Agreement or at law, terminate this Agreement and NDC's use of the
      Services if NDC does not effect payment in full within ten (10) days of
      the Company's written demand therefor.  NDC agrees to reimburse the
      Company for all costs and expenses, including reasonable attorney's fees,
      incurred by the Company in enforcing collection of any moneys due it
      under this Agreement.

      3.   TERM AND TERMINATION:

      a.        This Agreement shall remain in full force and effect
           for an initial term of five (5) years, beginning upon the
           effective date set forth above, and shall be automatically
           extended for successive one (1) year periods on the same
           terms and conditions expressed herein, or as may be amended,
           unless either party gives the other party written notice of
           termination at least thirty (30) days prior to the expiration
           of the initial term or any extensions or renewals thereof.
           Termination of this Agreement shall not terminate NDC's
           obligation to pay the Company for all services performed
           under the Agreement prior to discontinuance of performance by
           the Company due to termination.

      b.        Except as provided in Paragraph 2 above, in the event
           that either party hereto fails in the performance of its
           obligations hereunder or breaches the terms or conditions
           hereof, the other party may, at its option, give written
           notice to the party which has failed to perform or has
           breached this Agreement of its intention to terminate this
           Agreement unless such breach or failure in performance is
           remedied within thirty (30) days of such notice.  Failure to
           remedy such a breach shall make this Agreement terminable, at
           the option of the aggrieved party, at the end of such thirty
           (30) day period unless notification is withdrawn.

      4.        CHANGE OF CHARGES: The Company shall have the right to 
      change the prices for any of the services at any time on or after the
      first year's anniversary date of this Agreement upon not less than
      sixty (60) days prior written notice to NDC.  Such new price shall
      be guaranteed to remain at the same level for a period of one (1)
      year from the effective date of such change.
   
                                    - 2 -

      Notwithstanding the above requirements, the Company shall have the right
      to increase the fees and charges paid by NDC to offset any increase in
      rates charged by any communications common carriers utilized by the
      Company in the provision of Services hereunder.  Any such increase shall
      become effective on the same day as the increase in rates charged by the
      communications common carrier becomes effective.

      Further notwithstanding the above requirements, the Company shall have
      the right to increase such fees and charges to offset any increase to the
      Company in the costs of providing the Services hereunder if any change in
      the rules, regulations or operating procedures of any Credit Card sponsor
      organization, service supplier or any cognizant Federal, State or local
      governmental agency or regulatory authority results in such cost
      increase.  Any such increase shall become effective as of the date on
      which the Company notifies NDC of such increase.
                
      5.        USE OF THE SERVICES: NDC agrees to utilize the Services in
      accordance with this Agreement, its exhibits, and the Company's
      reasonable Service instructions and specifications and to provide
      the Company with the necessary data in the proper format to enable
      the Company to properly furnish the services.
                
      6.        LIMITATION OF LIABILITY:

      a.        The Company shall not be liable for failure to provide
           the Services if such failure is due to any cause or condition
           beyond its reasonable control.  Such causes or conditions
           shall include but shall not be limited to, acts of God or of
           the public enemy, acts of the Government in either its
           sovereign or contractual capacity, fires, floods, epidemics,
           quarantine restrictions, strikes, shortages of labor or
           materials, freight embargoes, unusually severe weather,
           electrical power failures, or other similar causes beyond the
           Company's control and the Company shall have no liability for
           losses, expenses or damages, ordinary, special or
           consequential resulting directly or indirectly from such
           causes. If the Company's failure to provide the Services is
           caused by the default of a subcontractor, and if such default
           arises out of causes beyond the control of both the Company
           and the subcontractor, the Company shall not be liable unless
           the supplies or Services to be furnished by the subcontractor
           were obtainable from other sources in sufficient time to
           permit the Company to fulfill its obligations hereunder.

      b.        The Company agrees to use its best efforts at all
           times to provide prompt and efficient services; however, the
           Company makes no warranties or representations regarding the
           Services except as specifically stated in this Paragraph 6.b.
           The Company shall use due care in processing all work

           submitted to it by NDC and agrees that it will, at its
           expense, correct any errors which are due solely to
           malfunction of the Company's computers, operating systems or
           programs, or errors by the Company's employees or agents.
           Correction shall be limited to rerunning of the job or jobs
           and/or recreating of data or program files.  The Company
           shall not be responsible in any manner for errors or failures
           of or errors in proprietary systems and programs other than
           those of the Company, nor shall the company be liable for
           errors or failures of NDC'S software or operational systems.
           THIS WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ALL OTHER
           WARRANTIES, AND SUBSCRIBER HEREBY WAIVES ALL OTHER
           WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY INCLUDING, BUT NOT
           LIMITED TO, ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR
           USE FOR A PARTICULAR PURPOSE.  Should there be any failure in
           performance or errors or omissions with respect to the
           information being transmitted, the Company's liability shall
           be limited to using its best efforts to correct such failure
           in performance or errors or omissions.  In no event, except
           as specifically set forth herein, shall the Company be liable
           to NDC or any third parties (including NDC's customers) for
           any claim, loss or damage, ordinary, special or
           consequential, or otherwise, even if the Company has been
           advised of the possibility of such damage. 

           Due to the nature of the services being performed by the Company,
           it is agreed that in no event will the Company be liable for any
           claim, loss, liability, correction, cost, damage or expense caused
           by the Company's performance or failure to perform hereunder which
           is not reported by NDC within one hundred twenty (120) days of
           such failure to perform.


      c.        NDC shall indemnify and hold harmless the company from
           and against any and all loss, damage, or expense or claims of
           damage or liability, ("claims") asserted against the Company
           by third parties arising out of the performance of services
           under this agreement or from information provided to the
           Company by NDC or NDC's customers, or arising out of the use
           of such information when furnished by the Company to NDC's
           customers or to other third persons at NDC's request, or to
           officers, employees and agents of NDC; provided, however,
           that such indemnity obligation does not apply in cases where
           such claims arise primarily from the negligence or
           intentional misconduct of the Company.

      d.        Liability of the Company in any and all categories and
           for any and all causes arising out of this agreement shall,
           in the aggregate, not exceed six (6) month's average billing
           to NDC taken over the twelve (12)

           alleged to have occurred, but if this agreement has not been in
           effect for twelve (12) months preceding such date, then over such
           fewer number of preceding months that this agreement has been in
           effect.

                              CERTAIN DEFINITIONS

     As used herein and in the Exhibits hereto, the following terms have the
following respective meanings (such meanings to be equally applicable to both
the singular and plural forms of the terms defined):

controlling, controlled by or under common control with NDC or the Company,
respectively.


<PAGE>   131

and B-1 through B-7 attached hereto, as the same may be supplemented, amended
or modified from time to time.

     "TAXES" means all forms of taxation, whether of the United States or
elsewhere and whether imposed by a local, municipal, state, federal, foreign or
other body or instrumentality, and shall include any related interest and
penalties imposed by any taxing authority.

     "TERM" is defined in Section 5.1.


                                   ARTICLE 2
                            SERVICES TO BE PROVIDED

     2.1 SERVICES.  The parties agree that, subject to the terms and conditions
of this Agreement, NDC shall provide to the Company the services described on
Exhibits A-1 through A-7 hereto in connection with the Company's operation of
the Business from and after the Closing Date (the "Services").  NDC shall
provide the Services substantially in the same manner, at the same level and
quantity, with the same quality of performance, and at and from the same
locations, as such Services have been provided to the Business prior to the
Closing.

     2.2 THE COMPANY'S COOPERATION.  The Company shall cooperate fully and
provide such assistance as is reasonably required for NDC to provide the
Services.

                                   ARTICLE 3
                         ADEQUATE STAFF AND FACILITIES

     NDC shall use commercially reasonable efforts, during the Term of this
Agreement, to maintain adequate staff, support services and facilities as may
be necessary to perform its responsibilities under this Agreement, in keeping
with the standards of accuracy and promptness observed by NDC in providing the
Services with respect to its own business.

                                   ARTICLE 4
                            PRICE AND PAYMENT TERMS

     4.1 PRICE FOR SERVICES.  The price to be paid by the Company for each
Service (the "Service Cost") shall initially be as set forth on Exhibits B-1
through B-7 hereto, and thereafter as the parties shall mutually agree.

     4.2 PAYMENT.  The Service Cost will be paid as follows:

         (a) Monthly Invoices.  After the end of each month during the Term, NDC
will provide to the Company an invoice for each Service showing the Service
Cost

                                     - 2 -
<PAGE>   132

therefor for such month just ended.  Upon request, NDC will provide the Company
with such supporting documentation as may be reasonably requested by the
Company.  Subject to the procedures for dispute set forth below, the Company
shall pay the amount shown on each such invoice within ten (10) days after
receipt thereof by means of a company check.  The Service Cost for any Service
that is provided for only part of a month shall be appropriately prorated.

         (b) Disputes.  In the event that the Company disagrees with any invoice
submitted by NDC as required by subsection (a) immediately above, the Company
shall promptly notify NDC of such disagreement following the Company's
determination of the disagreement.  The parties shall then cooperate to resolve
the dispute, with NDC providing the Company with such supporting documentation
relating to the calculation of the Service Cost as the Company may reasonably
request.  If the parties do not resolve the dispute within twenty (20) days
after NDC's receipt of the Company's dispute notice, either party can submit
the dispute to arbitration, in accordance with Article 6 hereof.

         (c) Other Documents.  NDC shall provide to the Company upon reasonable
request any reports or summaries relating to the Service Costs, which the
Company may need for preparing financial statements, tax returns or otherwise.

     4.3 TAXES.  Any transaction, excise, sales or similar Tax imposed on or
measured by the rendering of a Service shall be the responsibility of the
Company.  All other Taxes associated with a Service shall be paid by NDC;
provided, however, that each party shall be responsible for its own income
Taxes.

                                   ARTICLE 5
                              TERM AND TERMINATION

     5.1 TERM.  This Agreement shall commence on the Closing Date and, unless
sooner terminated in accordance with Section 5.2 below or any of Exhibits A-1
through A-7 hereto, shall continue in effect for a term (the "Term") expiring
on the third (3rd) anniversary of the Closing Date.

     5.2 TERMINATION.

         (a) By the Company.  The Company shall be entitled to terminate this
Agreement at any time, in whole or in part with respect to any or all of the
Services, by providing thirty (30) days' written notice to NDC.

         (b) By NDC.  NDC shall not be entitled to terminate this Agreement, 
except in the event that the Company is in material breach of this Agreement 
and such breach remains uncured for more than 30 days after notice thereof has 
been provided by NDC to the Company; provided, that if such breach is not 
capable of being cured within 30 days of such notice, and if the Company, upon 
receipt of such notice, promptly commences and diligently pursues the cure to 
completion as soon as reasonably possible, 

                                     - 3 -
<PAGE>   133

then such 30-day period shall be extended for the period of time which is 
reasonably necessary to cure the breach.

     5.3 EFFECT OF TERMINATION.  Upon termination of this Agreement, all rights
and obligations of each party hereunder shall cease as of the date of the
termination, and any amounts owed by either party pursuant to this Agreement
shall be paid in full.  In addition, upon any termination of this Agreement,
NDC shall promptly return to the Company any property of the Company used in
connection with the provision of the Services.  Notwithstanding the foregoing,
the termination of this Agreement pursuant to any of the provisions hereof
shall be without prejudice to any rights, or diminution of any obligation or
liability of either party, that may have accrued prior to the effective date of
such termination.  In addition, the provisions of Article 7 and Section 8.1
shall survive the termination of this Agreement.


                                   ARTICLE 6
                          DISPUTE RESOLUTION PROCEDURE

breach hereof, or coverage of this arbitration provision, which is not settled
by NDC and the Company, shall be settled by arbitration in accordance with the
procedures therefor set forth in the Purchase Agreement.

                                   ARTICLE 7
                                INDEMNIFICATION

     7.1 LIMITATION OF LIABILITY.  Except to the extent provided in Sections
7.2 and 7.3 hereof, nothing in this Agreement is intended to impose upon NDC,
and NDC does not intend to assume in this Agreement, any of the risks
associated with operation of the Business, including, without limitation,
product or service quality and liability therefor, except to the extent NDC is
providing the services associated with such product or service quality and then
subject to the provisions in Section 7.2.  Except as provided elsewhere in this
Agreement, neither party shall have any liability to the other party for any
costs, damages, expenses, liabilities or losses incurred by such other party in
connection with this Agreement or the performance of either party's obligations
hereunder, whether such claim of liability arises in an action at law or in
equity, and whether such claim sounds in contract or tort or otherwise.

     7.2 INDEMNIFICATION BY NDC.  Subject to the provisions of Section 7.4, NDC
hereby agrees to indemnify and hold harmless the Company, its Affiliates, and
their respective directors, officers, employees, successors and assigns
(collectively, "Agents"), from and against any and all claims, demands, causes
of action and lawsuits ("Claims") (including Claims against the Company, its
Affiliates or their respective Agents by NDC, its Affiliates or their
respective Agents, or any third party), and liabilities, penalties, judgments,
losses, injuries, damages, costs, fees and expenses (including, without
limitation, costs of defense, settlement, and reasonable attorneys' fees and
expenses relating to matters or actions arising under this Agreement)
("Damages"), suffered or incurred by the Company, its Affiliates or their
respective Agents, arising out of or resulting from:

     (a) any material breach of this Agreement by NDC;

     (b) the fraud, negligence or willful misconduct of NDC in connection with
the performance of its obligations under this Agreement;

     (c) any failure of any NDC Benefit Plan (provided that, for these purposes
"NDC Benefit Plan" shall include, without limitation, any agreement or plan
which is otherwise an NDC Benefit Plan but is maintained in the future, rather
than presently or within the immediately preceding two years) or, solely to the
extent administered by NDC, Company Benefit Plan (as defined below), or the
administration thereof, to comply with the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), the Internal Revenue Code of 1986, as
amended (the "Code") (including without limitation all provisions compliance
with which is required for any intended favorable tax treatment) or other
applicable law other than as a result of the failure of the Company to comply
with its obligations under the terms of the NDC Benefit Plans, Company Benefit
Plans, ERISA or the Code; provided that, for these purposes "Company Benefit
Plans" shall mean the following agreements or plans which cover the Company's
employees (including without 

                                     - 5 -
<PAGE>   135
limitation agreements and plans maintained by NDC), including incentive bonus, 
vacation and severance programs

         (i) any employee benefit plan as defined in ERISA or under which the
Company, with respect to the Company's Employees, has any outstanding, present
or future obligation or liability, or under which any of the Company's
Employees has any present or future right to benefits which are covered by
ERISA; or

         (ii) any other pension, profit sharing, retirement, deferred 
compensation, stock purchase, stock option, incentive, bonus, vacation, 
severance, disability, hospitalization, medical, life insurance, or other 
employee benefit plan, program, policy, or arrangement, which the Company 
maintains or to which the Company has any outstanding present or future 
obligations to contribute or make payments under, whether voluntary, 
contingent, or otherwise; and

     (d) any pension, welfare or other benefit plan which Damages arise under
ERISA or the Code solely by virtue of the Company being in a "controlled group"
with NDC at any relevant time.

     7.3 INDEMNIFICATION BY THE COMPANY.  Subject to the provisions of Section
7.4, the Company hereby agrees to indemnify and hold harmless NDC, its
Affiliates, and their respective Agents from and against any and all Claims
(including Claims against NDC, its Affiliates or their respective Agents by the
Company, its Affiliates or their respective Agents, or any third party) and
Damages suffered or incurred by NDC, its Affiliates or their respective Agents,
arising out of any material breach of this Agreement by the Company or
resulting from the provision of Services under this Agreement other than any
and all Claims or Damages arising out of or resulting from any material breach
of this Agreement by NDC or the fraud, negligence or willful misconduct of NDC
in connection with the performance of its obligations under this Agreement.

     7.4 INDEMNIFICATION PROCEDURES.

         (a) In the event that, from and after the Closing Date, a third party
asserts a Claim against NDC, its Affiliates (other than the Company) or their
respective Agents (the "NDC Indemnitees"), or the Company, its Affiliates
(other than NDC) or their respective Agents (the "Company Indemnitees"), with
respect to any matter to which the indemnities set forth in this Article 7
apply (a "Third Party Claim"), the NDC Indemnitee or the Company Indemnitee, as
the case may be, against whom the Third Party Claim is asserted (the
"Indemnified Party") shall give the Company or NDC, as the case may be (the
"Indemnifying Party"), prompt notice of such Third Party Claim.  The
Indemnifying Party, at its own expense, shall have the right to undertake the
defense of such Third Party Claim by retaining counsel of its own choosing
(after giving notice of such retention of counsel to the Indemnified Party),
which counsel shall be reasonably satisfactory to the Indemnified Party.  If an
expense or cost is found to be associated with an Indemnified Party's failure
to give timely notice to the Indemnifying Party, the Indemnified Party shall
pay such expense or cost; provided, that in agreeing to pay such expense or
cost the Indemnified Party shall not be deemed in any way to have waived its
right to indemnification hereunder, net of any such expense or cost.  In the
event that a party from whom indemnification is sought chooses not to undertake
the defense of any Third Party Claim asserted (and hereby agrees to provide
written notice of such decision to the other party), and the party seeking
indemnification does undertake the defense of such Third Party Claim, and the
party from whom indemnification is sought is subsequently held to be liable for
such Third Party Claim, the party from whom indemnification is sought agrees
that it will fully indemnify the party seeking indemnification for the Damages
it may owe to such party in connection with such Third Party Claim, including,
without limitation, attorneys fees and other expenses related to the defense of
such Third Party Claim which are incurred by the party seeking indemnification.

         (b) Notwithstanding anything to the contrary in this Section 7.4, if 
there is a reasonable probability in the Indemnified Party's judgment that a 
Third Party Claim may materially and adversely affect the Indemnified Party 
other than as a result of money damages ("Non-Monetary Claims"), the Indemnified
Party will have the right to defend or co-defend (in each case, at the
Indemnified Party's expense), compromise or settle such Non-Monetary Claim to
the extent it relates to the Indemnified Party or the Indemnified Party's
business; provided that if the Indemnifying Party does not consent in writing
to any such settlement or compromise (which consent shall not be unreasonably
withheld, conditioned or delayed) the settlement or compromise shall be at the
Indemnified Party's expense.

         (c) The Indemnifying Party will provide each Indemnified Party with 
access to all records and documents of the Indemnifying Party relating to any 
Third Party Claim.  The Indemnified Party will provide the Indemnifying Party 
with access to all records and documents of the Indemnified Party relating to 
any Third Party Claim.


                                     - 7 -
<PAGE>   137


         (d) Notwithstanding any other provision of this Agreement, the 
liability of an Indemnifying Party under this Agreement shall be limited to the
direct damages (which the Company and NDC agree shall also include lost profits
only with respect to any Claim arising out of or resulting from any material 
breach of this Agreement or fraud or willful misconduct in connection with the
performance of this Agreement) of the Indemnified Party and shall not otherwise
include incidental, consequential, indirect, special, punitive, exemplary or
other similar damages awarded as such directly to such party, other than
compensatory damages.  In calculating any amount of actual damages to be paid
by NDC or the Company as set forth in this Article 7, the amount of such
damages shall be reduced by all net tax benefits and other reimbursements
credited to or received by the other party, relating to such damages.


                                   ARTICLE 8
                                 MISCELLANEOUS

     8.1 CONFIDENTIALITY.

         (a) Each party agrees not to use, copy or disclose the trade secrets 
and confidential information of the other party, except as permitted by this
Agreement.  Each party shall treat the other's confidential and secret
information with at least that degree of care it uses with respect to its own
such information.  Each party will give access to the other party's
confidential information only to such of its personnel and representatives as
have a need to such access for the purpose of providing the services hereunder,
and to no other person whatsoever.  The requirements herein contained with
respect to non-disclosure and non-use and protection of each party's trade
secrets and confidential information shall permanently survive termination of
any other provisions of this Agreement.  If either party is ordered by a court
or Governmental Authority of competent jurisdiction to disclose trade secrets
or confidential information, or if it is served with or otherwise becomes aware
of a motion or similar request that such an order be issued, then such party
will not be liable to the other party for disclosure of trade secrets or
confidential information required by such order if the disclosing party
complies with the following requirements:  (1) if an already issued order calls
for immediate disclosure, then the disclosing party promptly moves for or
otherwise requests a stay of such order to permit the other party to respond;
(2) the disclosing party promptly notifies the other party of the motion or
order; and (3) the disclosing party does not oppose a motion or similar request
by the other party for an order protecting the confidentiality of the trade
secrets and confidential information including joining or agreeing to (or
non-opposition to) a motion for leave to intervene by such other party.

         (b) The term "trade secrets" means information related to a party (1)
which derives economic value, actual or potential, from not being generally
known to or readily ascertainable by other persons who can obtain economic
value from its disclosure or use, and (2) which is the subject of efforts by
said party that are reasonable under the circumstances to maintain its secrecy.

                                     - 8 -
<PAGE>   138



         (c) The term "confidential information" means information that is
confidential to the business of a party and is not a trade secret; provided,
however, that confidential information does not include information which is or
becomes generally known to the public without any breach by a party of its
duties to the other party.  Assuming that the foregoing criteria are met,
confidential information also includes information which has been disclosed to
a party and which such party is obligated to treat as confidential.

     8.2 SUCCESSORS AND ASSIGNS.  This Agreement may not be assigned by any
party hereto without the prior written consent of the other party, which
consent shall not be unreasonably withheld, conditioned or delayed.
Notwithstanding the foregoing, the Company may assign or otherwise transfer all
of its rights and/or obligations hereunder to any Affiliate of the Company or
to any entity or entities, or any assignee of such entity or entities, which
acquires, by purchase, operation or law or otherwise, all or a substantial
portion of the assets of the Business.

     8.3 GOVERNING LAW.  The construction, validity and enforceability of this
Agreement shall be governed by the internal laws of the State of Georgia,
without regard to the conflict of laws principles thereof.

     8.5 NO WAIVER.  The failure of either party at any time to require

way affect the right of such party to require performance of that provision.

shall not be construed as a waiver of any

continuing or succeeding breach of such provision, a waiver of the provision

assignment would constitute a breach thereof.  Any obligation of Seller under 
the Purchase Agreement to effect the transfer of any Assigned Agreement to

     (a) The Holders shall have the right, at any time following the end of the
eleventh month after an IPO, by written notice (the "Demand Notice") given to
the Issuer, to request the Issuer to register under and in accordance with the
provisions of the Securities Act all or any portion of the Registrable
Securities designated by such Holders, provided that the number of securities
to be registered are not less than the Minimum Registration Amount.  Upon
receipt of any such Demand Notice, the Company shall promptly notify all other
Holders of the receipt of such Demand Notice and allow them the opportunity to
include Registrable Shares held by them in the proposed registration by
submitting their own Demand Notice.  Notwithstanding the foregoing, the
following limitations shall be applicable to any such requested registration:

           (i) The right to participate in the requested registration shall be

                                    - 4 -
<PAGE>   155
           (ii) The Issuer shall be entitled on two occasions during each
      Demand Period (as defined in Section 3.1(b)) to postpone the filing of
      any registration statement otherwise required to be prepared and filed by
      the Issuer pursuant to this Section 3.1 for a reasonable period of time, 
      but not in excess of 90 days (a "Delay Period"), if any executive officer
      of the Issuer determines in good faith that in such executive officer's
      reasonable judgment the registration and distribution of the Registrable
      Securities covered or to be covered by such registration statement would
      materially interfere with any pending or contemplated material public
      offering of equity securities by the Issuer or would require premature
      disclosure by the Issuer of any material corporate development (including
      potential material business combination and merger and acquisition
      transactions) affecting the Issuer and the Issuer promptly gives the
      Holders written notice of such determination, containing a general
      statement of the reasons for such postponement and an approximation of
      the period of the anticipated delay; provided, however, that (i) the
      aggregate number of days include in all Delay Periods during any Demand
      Period (as defined in Section 3.1(b)) shall not exceed the aggregate of
      (x) 90 days minus (y) the number of days occuring during all Hold Back
      Periods (as defined in Section 3.3) (other than any Hold Back Period with
      respect to an offering in which the Holders had the opportunity to
      participate and in which the Holders were able to sell at least 50% of
      the Registrable Securities that the Holders requested be included in such
      Registration Statement) during the Demand Period, and (ii) a period of at
      least 90 days shall elapse between the termination of any Delay Period or
      Hold Back Period and the commencement of the next succeeding Delay Period
      (regardless of whether the commencement of such succeeding Delay Period
      occurs during the same Demand Period as the preceding Delay Period).  If
      the Issuer shall so postpone the filing of a registration statement, the
      Holders of Registrable Securities to be registered shall have the right
      to withdraw the request for registration by giving written notice from
      the Holders of a majority of the Registrable Securities that were to be
      registered to the Issuer (x) within 30 days after receipt of the notice
      of postponement or, if earlier, (y) the date such Delay Period is
      terminated (and, in the event of such withdrawal, such request shall not
      be counted for purposes of determining the number of requests for
      registration to which the Holders of Registrable Securities are entitled
      pursuant to this Section 3.1).  The Issuer shall not be entitled to
      initiate a Delay Period pursuant to Section 3.1 unless it shall (A)
      concurrently prohibit sales by other security holders of the Issuer under
      registration statements covering securities held by such other security
      holders and (B) in accordance with the Issuer's policies from time to
      time in effect, prohibit purchases and sales in the open market by
      officers and directors (and persons holding equivalent positions) of the
      Issuer.

           (iii) Holders of a majority in number of the Registrable Securities
      to be included in a registration statement pursuant to this Section 3.1
      may, at any time prior to the effective date of the registration
      statement relating to such registration, revoke such request by providing
      a written notice to the Issuer revoking such request.  The Holders who
      revoke such request shall reimburse the Issuer for all its 



                                    - 5 -
<PAGE>   156
      out-of-pocket expenses incurred in the preparation, filing and processing
      of the registration statement through the date of revocation; provided, 
      however, that, if such revocation was based on the Issuer's failure to 
      comply in any material respect with its obligations under this Agreement,
      such reimbursement shall not be required.  In the event the Holder revokes
      such request for registration and such revocation was not based upon the
      Issuer's failure to comply in any material respect with the obligations
      hereunder, the Holders whose Registrable Securities were to be included
      in such registration may not submit a Demand Request for 180 days after
      such revocation.

     (b) Except as otherwise provided in this Agreement, the Issuer shall be
obligated to register Registrable Securities pursuant to this Section 3.1 on
three occasions only; provided that (i) the Issuer shall only be obligated to
effect one registration of Registrable Securities pursuant to this Section 3.1
during each 12 month period commencing following the end of the eleventh month
after an IPO (each such period referred to as "Demand Period"); and (ii) such
obligation shall not be deemed satisfied if (x) the registration statement
does not become effective because of a material adverse change in the Issuer;
(y) such registration statement does become effective and the method of
disposition is an underwritten public offering and any of the Registrable
Securities included in such registration are not sold after execution of an
underwriting agreement with respect thereto because the obligations of any
underwriter to purchase any Registrable Securities are excused for any reason
other than default or consent by a Holder; or (iii) the number of Registrable
Securities to be sold is reduced by greater than 15 percent pursuant to Section
3.1(d) or (e).

     (c) Subject to Section 3.1(a)(ii), from the date of receipt of a Demand
Notice from the Holders pursuant to Section 3.1(a) until the completion of the
period of distribution of the registration contemplated therein not to exceed
the period determined in accordance with Section 3.5(b), the Issuer will not
file with the Commission any other registration statement with respect to its
equity securities, whether for its own account or that of other security
holders, provided that the Issuer shall not be prohibited from filing any
registration statements on Forms S-4 or S-8 or any successor form.  Except for
a period of 120 days from receipt of a Demand Notice from the Holders (or from
the end of any Delay Period if such Demand Notice has not been withdrawn or
revoked during such Delay Period) with respect to a requested registration
which provides for offers and sales of Registrable Securities on a continuous
or delayed basis pursuant to Rule 415 under the Securities Act (or any
successor provision), the restriction on the filing of a registration statement
by the Issuer set forth in this Section 3.1(c) shall not apply.The Issuer shall
be entitled to include in any registration statement referred to in this
Section 3.1 shares of its capital stock to be sold by the Issuer for its own
account or by other stockholders of the Issuer pursuant to other registration
rights agreements, provided the registration statement relates to an
underwritten public offering and in the opinion of the managing underwriter
such inclusion would not adversely affect the marketing of the securities to be
sold by the Holders of Registrable Securities.

                                    - 6 -
<PAGE>   157


     (d) Notwithstanding anything to the contrary in this Section 3.1, the
amount of Registrable Securities to be included in an underwritten public
offering may be reduced if and to the extent the managing underwriter shall be
of the opinion that such inclusion would adversely affect the marketing of the
Registrable Securities to be sold in such underwritten public offering
including the price at which such Registrable Securities will be sold.  If such
a determination is made, (i) the number of shares to be included by the Issuer
and the number of shares to be included by stockholders other than the Holders
shall be reduced first; and then (ii) the number of Registrable Securities to
be sold shall be reduced as provided in Section 3.1(e).

     (e) If a requested registration pursuant to this Section 3.1 involves an
underwritten public offering and the number of Registrable Securities requested
to be included in such registration is required to be reduced as described in
Section 3.1(d), then the Issuer will reduce the number of Registrable
Securities requested to be included by each Holder pro rata in the proportion
that the percentage of Restricted Shares requested by that Holder to be
included bears to the total number of Registrable Securities requested to be
included in that registration; provided, however, that the Holders requesting
registration may agree among themselves a different priority.

     (f) If any requested registration pursuant to this Section 3.1 is in the
form of an underwritten public offering, the Holders of a majority in number of
the Registrable Securities to be included in the offering shall be entitled,
after consultation with the Issuer, to select the manager or co-managers that
will administer the offering.

     3.2. Incidental Registration.  If the Issuer at any time proposes to
register any of its equity securities under the Securities Act (other than
pursuant to a registration statement on Forms S-4 or S-8, or any successor
forms), whether or not for sale for its own account, and the registration form
to be used may be used for the registration of Registrable Securities, it shall
at such time give each Holder of Registrable Securities prompt written notice
of its intentions and, upon the written request of any such Holder made within
twenty (20) days after the receipt of any such notice (which request shall
specify the Registrable Securities intended to be disposed of by such Holder
and the intended method of disposition thereof), the Issuer shall use its
commercially reasonable efforts to effect the registration under the Securities
Act of all Registrable Securities which the Issuer has been so requested to
register by the Holders thereof, to the extent required to permit the
disposition (in accordance with the intended methods thereof as aforesaid) of
the Registrable Securities so to be registered, provided that:

     (a) if, at any time after giving written notice of its intention to
register any securities and, prior to the effective date of the registration
statement filed in connection with such registration, the Issuer shall
determine for any reason not to register such securities, the Issuer may, at
its election, give written notice of such determination to each Holder of
Registrable Securities and, thereupon, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay the Registration Expenses in connection
therewith);
     

                                    - 7 -
<PAGE>   158


     (b) if such registration shall be in connection with the Issuer's initial
underwritten public offering (the "Initial Offering"), the Holders shall only
be entitled to request registration of up to the number of Registrable
Securities equal to one-half of the number of Registrable Securities (the
"Maximum Number") which Maximum Number shall be reduced by the number of
Registrable Securities previously sold pursuant to exercise of the Put Right
(as defined in the Operating Agreement) ; and further provided, that if the
managing underwriter advises the Issuer that, in its view, the registration and
distribution of the number of equity securities of the Issuer (including the
Registrable Securities) which the Issuer, the Holders, and all other persons
intend to include in such registration exceeds the largest number of equity
securities which can be sold without materially adversely affecting the
marketing of the securities to be sold in such underwritten public offering
(including the price at which such securities may be sold)(the "Maximum
Offering Size"), the Issuer shall include in such registration, in the
following priority, up to the Maximum Offering Size:  (i) first, the number of
Registrable Securities proposed to be sold by the Holders , which shall have
priority in being included in such registration, (ii) second, all securities
proposed to be sold by the Issuerthe ), and (iii) third, the number of shares
proposed to be sold by all other security holders; and

     (c) if such registration shall be in connection with an underwritten
public offering other than the Initial Offering and the managing underwriter
advises the Issuer that, in its view, the registration and distribution of the
number of equity securities of the Issuer (including the Registrable
Securities) which the Issuer, the Holders, and all other persons intend to
include in such registration exceeds the Maximum Offering Size, the Issuer
shall include in such registration, in the following priority, up to the
Maximum Offering Size:   (i) first, all securities being sold by the Issuer,
which shall have priority in being included in such registration, (ii) second,
all securities proposed to be sold by the Holders and all security holders
other than Ambassador pro rata in proportion to the number of shares proposed
to be sold by them (or based on the proposed offering price of the total number
of securities included in such underwritten public offering requested to be
included by them if shares of common stock are not being offered), and (iii)
third, the securities proposed to be sold by Ambassador.

     3.3. Holdback Agreements.

     (a) If requested by the managing underwriter in connection with any
underwritten public offering by the Issuer, each Holder of Registrable
Securities, if requested by the managing underwriter of such public offering,
will agree not to effect any public sale or distribution under the Securities
Act, of any Registrable Securities, and not to effect any such public sale or
distribution of any other equity security of the Issuer or other security
convertible into or exchangeable or exercisable for any equity security of the
Issuer (in each case, other than as part of such public offering) during the
five (5) Business Days prior to, and during the 120-day period (or such longer
period as requested by the underwriters and agreed to by the Holders) which
begins on the effective date of such registration statement (each such period 
being referred to in this Agreement as a "Hold 


                                    - 8 -
<PAGE>   159

Back Period"), provided that (i) Ambassador and the executive officers and 
directors of the Issuer shall be bound by the same selling restrictions as are 
applied to the Holders and the managing underwriter will not grant waiver of 
such restrictions to any other Person unless waivers on substantially the same 
terms are granted to the Holders; and (ii) each Holder of Registrable 
Securities shall receive written notice of such registration at least two (2) 
Business Days prior to the anticipated beginning of the five (5) day period 
referred to above.

     (b) The Issuer shall not effect any public sale or distribution of any of
its equity securities or of any security convertible into or exchangeable or
exercisable for any equity security of the Issuer (other than any such sale or
distribution of such securities in connection with any merger or consolidation
by the Issuer or any subsidiary of the Issuer or the acquisition by the Issuer
or a subsidiary of the Issuer of the capital stock or substantially all the
assets of any other person or in connection with an employee stock ownership or
other benefit plan) during the five (5) Business Days prior to the effective
date of such registration statement.

     3.4 Designation of Underwriter.  In the case of any registration pursuant
to the provisions of Section 3.2 hereof which is proposed to be effected
pursuant to a firm commitment underwriting, the Issuer shall select the
managing underwriter after consultation with MasterCard, and all Holders of
Registrable Securities participating in the registration shall sell their
Registrable Securities only pursuant to such underwriting.

     3.5. Registration Procedures.  If and whenever the Issuer is required to
use its commercially reasonable efforts to effect the registration of any
Registrable Securities under the Act, the Issuer shall:

     (a) promptly, and in any event within 30 days, prepare and file with the
Commission a registration statement with respect to such securities, make all
required filings with the NASD and use commercially reasonable efforts to cause
such registration statement to become effective as promptly as practicable
thereafter;

     (b) prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective and to comply
with the provisions of the Securities Act with respect to the disposition of
all securities covered by such registration statement until such time as all of
such securities have been disposed of in accordance with the intended methods
of disposition by the seller or sellers thereof set forth in such registration
statement, but in no event for a period of more than six months after such
registration statement becomes effective; provided, however, that in the case
of a registration statement on Form S-3 (or any successor form) which the
Holders shall have requested providing for offers and sales of Registrable
Securities on a continuous or delayed basis pursuant to Rule 415 under the
Securities Act (or any successor provision), the Issuer's obligations under 
this paragraph 3.5(b) shall not be subject to the foregoing six month 
limitation;


                                    - 9 -
<PAGE>   160


     (c) furnish to the Holders and to counsel (if any) selected by Holders of
a majority in number of the Registrable Securities covered by such registration
statement for review and comment (but not approval of the Holders or their
counsel except with respect to any statement in the registration statement
which relates to the Holder) copies of all documents proposed to be filed with
the Commission in connection with such registration;

     (d) furnish to each Holder of the securities being sold such number of
conformed copies of such registration statement and of each such amendment and
supplement thereto (in each case including all exhibits, except that the Issuer
shall not be obligated to furnish any Holder with more than two copies of such
exhibits), such number of copies of the prospectus included in such
registration statement (including such preliminary prospectus and any summary
prospectus), in conformity with the requirements of the Act, and such other
documents, as such Holder may reasonably request in order to facilitate the
disposition of the securities owned by such selling Holder;

     (e) use its commercially reasonable efforts to register or qualify such
securities covered by such registration statement under such other securities
or blue sky laws of such jurisdictions as each seller of the Registrable
Securities shall reasonably request, and do any and all other acts and things
which may be necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the securities owned by such seller,
except that the Issuer shall not for any such purpose be required to qualify
generally to do business as a foreign corporation in any jurisdiction wherein
it is not so qualified, or to consent to service of process in any such
jurisdiction other than process served in connection with alleged violations by
the Issuer of the securities laws of such jurisdiction;

     (f) notify the Holders of any Registrable Securities covered by such
registration statement promptly and (if requested) confirm such notice in
writing, (i) when a prospectus or any prospectus supplement or post-effective
amendment has been filed, and, with respect to such registration statement or
any post-effective amendment, when the same has become effective, (ii) of any
request by the Commission for amendments or supplements to such registration
statement or the related prospectus or for additional information regarding
such Holders, (iii) of the issuance by the Commission of any stop order
suspending the effectiveness of such registration statement or the initiation
of any proceedings for that purpose, (iv) of the receipt by the Issuer of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, and (v) of the happening of any event that requires the making of any
changes in such registration statement, prospectus or documents incorporated or
deemed to be incorporated therein by reference so that they will not contain 
any untrue statement of a material fact or omit to state any material fact 
required to be stated therein or necessary to make the statements therein not 
misleading;

     (g) otherwise use its commercially reasonable efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security 

                                   - 10 -

<PAGE>   161

holders, as soon as reasonably practicable, an earnings statement
covering the period of at least twelve (12) months, but not more than eighteen
(18) months, beginning with the first month after the effective date of the
registration statement, which earnings statement shall satisfy the provisions
of Section 11(a) of the Act;

     (h) use its commercially reasonable efforts to list such securities on any
stock market on which the Shares are then listed, if such securities are not
already so listed and if such listing is then permitted under the rules of such
exchange, and to provide a transfer agent and registrar for such Registrable
Securities not later than the effective date of such registration statement.

     (i) if such registration is with respect to an underwritten offering
undertaken pursuant to Section 3.1, take all appropriate and commercially
reasonable actions requested by the Holders of a majority of the Registrable
Securities being sold in connection therewith (including those reasonably
requested by the managing underwriters) in order to expedite or facilitate the
disposition of such Registrable Securities;

     (j) if such offering is in connection with an underwritten public offering
(i) use commercially reasonable efforts to obtain opinions of counsel to the
Issuer and updates thereof (which opinions (in form, scope and substance) shall
be reasonably satisfactory to the managing underwriters and their counsel) as
to the matters customarily covered in opinions requested in underwritten
offerings and such other matters as may be reasonably requested by such counsel
and underwriters and have such opinions addressed to each selling Holder of
Registrable Securities, (ii) use commercially reasonable efforts to obtain
"cold comfort" letters and updates thereof from the independent certified
public accountants of the Issuer (and, if necessary, any other independent
certified public accountants of any subsidiary of the Issuer or of any business
acquired by the Issuer for which financial statements and financial data are,
or are required to be, included in the registration statement), addressed to
each selling Holder of Registrable Securities covered by the registration
statement (unless such accountants shall be prohibited from so addressing such
letters by applicable standards of the accounting profession) and each of the
underwriters, such letters to be in customary form and covering matters of the
type customarily covered in "cold comfort" letters in connection with
underwritten offerings, (iii) if requested, provide indemnification provisions
and procedures substantially to the effect set forth in Section 3.7 hereof with
respect to all parties to be indemnified pursuant to said Section (the above
shall be done at each closing under such underwriting or similar agreement, or
as and to the extent required thereunder).
    
     For purposes of paragraph (b) of this Section 3.5, (i) the period of
distribution of securities in an underwritten public offering shall be deemed
to extend until the later of the date each underwriter has completed the
distribution of all securities purchased by it and the termination of the
period in which prospectuses must be delivered under Rule 174 of the Securities
Act, and (ii) the period of distribution of securities in any other
registration shall be deemed to extend until the earlier of the sale of all
securities covered thereby and one hundred twenty (120) days after the
effective date thereof; provided, however, in the 

                                   - 11 -
<PAGE>   162

case of a registration statement on Form S-3 (or any successor provision) which
the Holders shall have requested providing for offers and sales pursuant to 
Rule 415 under the Securities Act (or any successor provision), the Issuer 
shall comply with its obligations under Section 5(b) until the Registrable 
Securities covered by such registration statement have been disposed of, but 
no more than a period of one year following the filing of such registration
statement, it being understood and agreed that the Issuer may suspend its 
obligations to amend or supplement such registration statement for reasonable 
periods of  time not to exceed 90 days from time to time (a "Suspension 
Period") if any executive officer of the Issuer determines in good faith that 
such amendment or supplement would require disclosure of any material corporate
development affecting the Issuer and the Issuer promptly gives notice to the 
Holders of the Registrable Securities included in such Registration Statement 
of such determination. The one year period during which the Issuer is obligated
to maintain such registration statement shall be extended for the duration of 
any Suspension Period.

     The Issuer may require each Holder of any securities as to which any
registration is being effected to furnish to the Issuer such information
regarding such Holder and the distribution of such securities as the Issuer may
from time to time reasonably request in writing and as shall be required by law
in connection therewith.  Each such Holder agrees to furnish promptly to the
Issuer all information required to be disclosed in order to make the
information previously furnished to the Issuer by such Holder not materially
misleading.

     In connection with each registration pursuant to Section 3.1 or 3.2 hereof
covering an underwritten public offering, the Issuer and each selling Holder
agrees to enter into a written agreement with the managing underwriter selected
in the manner herein provided in such form and containing such provisions as
are customary in the securities business for such an arrangement between major
underwriters and companies of the Issuer's size and investment stature and
selling security holders, provided that such agreement shall not contain any
such provision applicable to the Issuer or any Holder which is inconsistent
with the provisions hereof.

     By acquisition of Registrable Securities, each Holder of such Registrable
Securities shall be deemed to have agreed that upon receipt of any notice from
the Issuer of the happening of any event of the kind described in Section
3.5(f) hereof, such Holder shall promptly discontinue such Holder's disposition
of Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3.5(f) hereof.  If 
so directed by the Issuer, each Holder of Registrable Securities shall deliver 
to the Issuer (at the Issuer's expense) all copies, other than permanent file 
copies, then in such Holder's possession of the prospectus covering such 
Registrable Securities current at the time of receipt of such notice.  In the 
event the Issuer shall give any such notice, the period mentioned in Section 
3.5(b) shall be extended by the number of days during the period from and 
including the date of the giving of such notice to and including the date when 
each seller of any Registrable Securities covered by such registration 
statement shall 

                                   - 12 -
<PAGE>   163

have received the copies of the supplemented or amended prospectus contemplated
by Section 3.5(f).

     3.6. Expenses.  Except as otherwise expressly provided in this Agreement,
the Issuer shall pay all Registration Expenses in connection with each
registration of Registrable Securities.

     3.7. Indemnification by the Issuer.  The Issuer shall indemnify and hold
harmless each Holder of Registrable Securities, each person who controls such
Holder of Registrable Securities within the meaning of either Section 15 of the
Act or Section 20(a) of the Exchange Act and the officers, directors, employees
and agents of each such Holder and control Person (each such Person being
sometimes hereinafter referred to as an "Indemnified Holder") from and against
all losses, claims, damages, liabilities, costs (including costs of preparation
and attorneys' fees) and expenses (including expenses of investigation)
(collectively, "Losses") arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any registration
statement or prospectus or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or based upon any omission or alleged
omission to state therein or necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading, except insofar
as such losses, claims, damages, liabilities or expenses arise out of or are
based upon any such untrue statement or omission or allegation thereof based
upon information relating to such Indemnified Holder and furnished in writing
to the Issuer by such Indemnified Holder expressly for use therein.  This
indemnity shall be in addition to any liability which the Issuer may otherwise
have.

     If any action or proceeding (including any governmental investigation or
inquiry) shall be brought or asserted against an Indemnified Holder in respect
of which indemnity may be sought from the Issuer, such Indemnified Holder shall
promptly notify the Issuer in writing, and the Issuer shall, at its expense,
assume the defense thereof, including the employment of counsel satisfactory to
such Indemnified Holder and the payment of all expenses.  The failure so to
notify the Issuer shall not relieve the Issuer from any obligation or liability
except to the extent (but only to the extent) that it shall finally be
determined by a court of competent jurisdiction (which determination is not
subject to appeal) that the Issuer has been materially prejudiced by such
failure.  Such Indemnified Holder shall have the right to employ separate
counsel in any such action and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified
Holder unless (i) the Issuer has agreed to pay such fees and expenses or (ii)
the Issuer shall have failed promptly to assume the defense of such action
or proceeding or has failed to employ counsel satisfactory to such Indemnified
Holder or (iii) the named parties to any such action or proceeding (including
any impleaded parties) include both such Indemnified Holder and the Issuer or
an Affiliate of the Issuer, and there may be one or more defenses available to
such Indemnified Holder which are additional to, or in conflict with, those
available to the Issuer or such Affiliate (in which case, if such Indemnified
Holder notifies the Issuer in writing that it elects to employ separate counsel
at the expense of the Issuer, the Issuer shall have the right to approve such
counsel (and 

                                   - 13 -
<PAGE>   164

such approval may not be unreasonably withheld) and the Issuer shall not have 
the right to assume the defense of such action or proceeding on behalf of such 
Indemnified Holder, it being understood, however, that the Issuer shall not, 
in connection with any one such action or proceeding or separate but 
substantially similar or related actions or proceedings in the same 
jurisdiction arising out of the same general allegations or circumstances, be 
liable for the fees and expenses of more than one separate firm of attorneys 
(together with appropriate local counsel) at any time for such Indemnified
Holder.  The Issuer shall not be liable for any settlement of any such action
or proceeding effected without its written consent, but if settled with its
written consent, or if there be a final judgment for the plaintiff in any such
action or proceeding, the Issuer agrees to indemnify and hold harmless such
Indemnified Holders from and against any loss or liability by reason of such
settlement or judgment.  Whether or not such defense is assumed by the Issuer,
no Indemnified Holder shall be subject to any liability for any settlement made
without its consent (but such consent shall not be unreasonably withheld).  The
Issuer shall not consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof the giving by the
claimant or plaintiff to each Indemnified Holder of a release, in form and
substance satisfactory to the Indemnified Holder, from all liability in respect
of such proceeding for which such Indemnified Holder would be entitled to
indemnification hereunder (whether or not any Indemnified Holder is a party
thereto).

     3.8. Indemnification by Holders of Registrable Securities.  Each Holder of
Registrable Securities agrees (severally but not jointly) to indemnify and hold
harmless the Issuer, its directors and officers and each Person, if any, who
controls the Issuer within the meaning of either Section 15 of the Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Issuer to such Holders, but only to the extentthat such Losses arise
from information relating to such Holder furnished in writing by such holder
expressly for use in any registration statement or prospectus, or any amendment
or supplement thereto, or any preliminary prospectus.  In case any action or
proceeding shall be brought against the Issuer or its directors or officers or
any such controlling person, in respect of which indemnity may be sought
against a Holder of Registrable Securities, such Holder shall have the rights
and duties given to the Issuer and the Issuer or its directors or officers or
such controlling person shall have the rights and duties given to each Holder
by the preceding paragraph.

     3.9. Contribution.  If the indemnification provided for in this Article
III is unavailable to or insufficient to hold harmless an indemnified party
under Section 3.7 or Section 3.8 hereof (other than by reason of exceptions or
other limitations provided in those Sections) in respect of any Losses referred
to therein, then each applicable indemnifying party, in lieu of indemnifying 
such indemnified party, shall contribute to the amount paid or payable by such 
indemnified party as a result of such losses, claims, damages, liabilities or 
expenses in such proportion as is appropriate to reflect the relative benefits 
received by the Issuer on the one hand and the Holders on the other hand from 
their sale of Registrable Securities or if such allocation is not permitted by 
applicable law, the relative fault of the Issuer on the one hand and of the 
Indemnified Holder on the other in connection with the statements or omissions 
which resulted in such losses, claims, 

                                   - 14 -
<PAGE>   165

damages, liabilities or expenses, as well as any other relevant equitable 
considerations.  The relative fault of the Issuer on the one hand and of the 
Indemnified Holder on the other shall be determined by reference to, among 
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to 
information supplied by the Issuer or by the Indemnified Holder and the 
parties' relative intent, knowledge, access to information and opportunity to 
correct or prevent such statement or omission.  The amount paid or payable by 
a party as a result of the losses, claims, damages, liabilities and expenses 
referred to above shall be deemed to include, subject to the limitations set 
forth in the second paragraph of Section 3.7, any legal or other fees or 
expenses reasonably incurred by such party in connection with investigating or 
defending any action or claim.

     The Issuer and each Holder of Registrable Securities agree that it would
not be just and equitable if contribution pursuant to this Section 3.9 were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the
immediately preceding paragraph.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.

     3.10. Participation in Public Offering.  No Holder may participate in any
public offering under Section 3.2 unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements complying with the requirements set forth in Section 3.5,
including provisions for indemnification of underwriters and (b) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements and this Agreement.

     3.11. Other Indemnification.  Indemnification similar to that specified
herein (with appropriate modifications) shall be given by the Issuer and each
Holder of Registrable Securities with respect to any required registration or
other qualification of securities under any state law or regulation or
governmental authority other than the Securities Act.

     3.12 Public Reports.  If the Issuer shall have filed a registration
statement pursuant to the requirements of Section 12 of the Exchange Act or a
registration statement pursuant to the requirements of the Securities Act, the
Issuer thereafter shall use its commercially reasonable efforts to file the 
reports required to be filed by it under the Exchange Act on a timely basis.

            REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY

     The Company represents, warrants and covenants to each Holder as follows:

     (a) The execution, delivery and performance of this Agreement by the
Company have been duly authorized by all requisite action and will not violate
any provision of law, any order of any court or other agency of government, the
Articles of Organization or Operating Agreement, or any provision of any
indenture, agreement or other instrument to which it or any of its properties
or assets is bound, or conflict with, result in a breach of or constitute (with
due notice or lapse of time or both) a default under any such indenture,
agreement or other instrument, result in the creation or imposition of any
lien, charge or encumbrance of any nature whatsoever upon any of the properties
or assets of the Company.

     (b) This Agreement has been duly executed and delivered by the Company and
constitutes the legal, valid and binding obligation of the Company, enforceable
in accordance with its terms.

     (c) Neither the Company nor any successor Issuer will consummate a
Conversion or other transaction resulting in the issuance of Shares or Other
Securities unless and until proper provision shall have been made for the
assumption and performance by the successor Issuer of all the Company's and
Issuer's obligations under this Agreement.

                                   ARTICLE V

     5.1. Headings.  The headings in this Agreement are for convenience of
reference only and shall not control or affect the meaning or construction of
any provisions thereof.

     5.3. No Inconsistent Agreements.  The Issuer will not hereafter enter into
any agreement with respect to its securities which is inconsistent with the
rights granted to the Holders of Registrable Securities in this Agreement.  The
Issuer has not previously entered into any continuing agreement with respect to
any of its debt or equity securities granting any registration rights to any
person.

     5.4. Remedies.  The Issuer acknowledges and agrees that in the event of
any breach of this agreement by it, the Holders would be irreparably harmed and
could not be made whole by monetary damages.  The Issuer accordingly agrees (a)
to waive the defense in any action for specific performance that a remedy at
law would be adequate, and (b) that the Holders, in addition to any other
remedy to which they may be entitled at law or in equity, shall be entitled to 
compel specific performance of this Agreement.

Newco; and

     WHEREAS, as partial consideration for the contribution of the Parent

Agreement shall not constitute an assignment or attempted assignment if such
assignment or attempted assignment would constitute a breach thereof.  Any
obligation of Parent under the Purchase Agreement to effect


<PAGE>   173



the transfer of any Assigned Agreement to Newco shall not be terminated or
abridged by this provision.

     5. Cooperation.  Parent agrees to cooperate with Newco in obtaining any

hereof, at the request of Newco, and without further consideration, Parent
shall execute and deliver such other instruments of assignment, transfer or
conveyance confirmation and take such other action as Newco may reasonably
request as necessary or desirable in order to more effectively transfer, convey
and assign to Newco the Parent Contributed Assets.

     7. Amendments.  No amendment, modification, or waiver of any provision of
this Agreement shall be valid or binding unless in writing and signed by each
of the parties hereto.

            MasterCard                 7.5%   [1,500,000 Units]
</TABLE>


The Percentage Ownership Interest of a Member may change from time to time as
provided in Articles 8, 16, and 18.

     6.2 NET EARNINGS INTEREST.  Notwithstanding the foregoing, the "Net
Earnings Interests" of the National Data Members and MasterCard shall be 99%
for National Data Members and 1% for MasterCard through May 31, 1998; 97% for
the National Data Members and 3% for MasterCard from June 1, 1998, through May
31, 1999; 95% for the National Data Members and 5% for MasterCard from June 1,
1999, through May 31, 2000; and at the Percentage Ownership Interests of the
Members after May 31, 2000, provided, however, the above percentages are based
on the National Data Members having an aggregate Percentage Ownership Interest
of 92.5% and MasterCard's having a Percentage Ownership Interest of 7.5% and if
the Members have different Percentage Ownership Interests, the respective Net
Earnings Interests will be adjusted proportionally.  For example if at any time
MasterCard's Percentage Ownership Interest were reduced to 3.75%, its Net
Earnings Interest thereafter would be 50% of the above amounts.  The aggregate
Net Earnings Interest allocated to the National Data Members shall be
reallocated among the National Data Members  based on their respective
Percentage Ownership Interests.

     6.3 CERTIFICATES; AUTHORIZED UNITS.  A Membership Interest shall be
evidenced by a certificate issued by the Company in the name of the Member,
which certificate shall bear the legend set forth in Section 24.14.  Such
certificate shall be based on units, with the total number of authorized units
of the Company initially being 20,000,000.  The number of authorized units may
be adjusted from time to time by a Majority in Interest.

The value of any property contributed by or distributed to a Member which holds
a Majority in Interest shall be subject to the provisions of Article 12.  A
Member's capital account shall also be increased or decreased to reflect any
items described in Treasury Regulation Section  1.704-1(b)(2)(iv) that are
required to be reflected in such Member's capital account under such Regulation
and which are not otherwise taken into account in computing such capital
account as provided above.

     7.5 INTEREST ON AND RETURN OF CAPITAL.  No Member shall be entitled to any
interest on such Member's Capital Account or on such Member's contributions to
the capital of the Company; and except as otherwise provided in Articles 10 and

all or any part of such Member's Capital Account or of such Member's
contributions to the capital of the Company.

     7.6 NO THIRD-PARTY RIGHTS.  Nothing contained in this Article 7 nor any
other provision of this Agreement shall be construed to create any rights or
benefits in any Entity, other than the Members, and their respective legal
representatives and permitted transferees, successors and assigns, subject to
the limitations on transfer contained herein.

                                   ARTICLE 8

                       ADDITIONAL FINANCIAL CONTRIBUTIONS

     8.1 WORKING CAPITAL COMMITMENT.  National Data shall make available to
Company working capital of no less than $15 million through (a) direct loans to
Company from one or more members of the National Data Group, (b) loans to
Company from third party lenders, or (c) retained earnings or other cash flow
of Company.  Any such working capital loans from any member of the National
Data Group (or any Affiliate thereof) shall bear interest at National Data's
Cost of Funds plus the amount computed in accordance with Exhibit A.  To the
extent that the Company has at any time a working capital loan from an Entity
or Entities other than National Data or has retained earnings or cash flow
available for working capital purposes, National Data's obligation hereunder
shall be correspondingly reduced; and at the earlier of an IPO or the time that
such other funds available for working capital purposes equals or exceeds $15
million, National Data's obligation hereunder shall cease.

     8.2. ADDITIONAL FUNDS FOR COMPANY.  Unless otherwise provided in this
Agreement, the Members may, but are not obligated to, make such additional
contributions of capital to the Company in such manner and at such times as the
Members unanimously may agree.  In addition, the National Data Members shall
have the right at any time to make additional contributions of capital to the
Company in such manner and on such terms as are determined by Approval of the
Board of Directors to be fair to and in the best interests of the Company and
the Members.  The additional capital provided by any National Data Member
shall, at such National Data Member's sole election, be treated as either (i) a
loan, or (ii) as an acquisition of additional equity.  In the event such
capital contribution is treated as a Term Loan (as hereinafter defined) or as
an acquisition of additional equity, MasterCard shall have the right to
participate in such Term Loan or acquisition of equity on the same terms as the
National Data Member(s).  MasterCard's participation shall not exceed a
percentage equal to its Percentage Ownership Interest at the time of the
contribution divided by the sum of (x) MasterCard Percentage Ownership Interest
and (y) the aggregate Percentage Ownership Interests of all of the National
Data Members.  A "Term Loan" shall be any loan, other than (a) extensions of
credit consistent with the terms in Section 8.1, (b) loans that bear interest
at no more than National Data's Cost of Funds, or (c) unsecured loans that have
an aggregate principal balance at any time in the aggregate of less than ten
million dollars

<PAGE>   28


($10,000,000).  Any transaction involving a Term Loan or additional equity in
which MasterCard has been offered the opportunity to participate in accordance
with the terms of this Section 8.2 shall not be subject to the provisions of
Article 12.  MasterCard shall be given written notice of any such opportunity
to make a capital contribution or loan and shall be given sixty (60) days to
elect to make such contribution or loan.  A National Data Member or Members may
make the entire contribution in accordance with the provisions of Article 12
for the period preceding the time MasterCard communicates its decision to
participate in the contribution or loan.  The participation rights granted to
MasterCard under this Article 8 shall cease to exist upon the first to occur of
(a) an IPO or (b) MasterCard's having less than the Minimum Equity.

                                   ARTICLE 9

                        ALLOCATION OF PROFITS AND LOSSES

     9.1 NET PROFIT.  The Company's Net Profit, if any, for each Fiscal Year
shall be allocated to the Members in the following manner and in the following
order of priority:

          (a) first, to the Members, in proportion to, and to the extent of,
     their respective shares of any distributions made or to be made by the
     Company pursuant to Section 10.1 hereof with respect to such Fiscal Year;
     then

          (b) second, to the Members, in proportion to, and to the extent of,
     the respective excesses, if any, of any distributions made or to be made
     by the Company pursuant to Section 10.1 hereof with respect to such Fiscal
     Year and for all prior Fiscal Years over the respective aggregate amounts
     of Net Profit theretofore allocated to such Members pursuant to Section
     9.1(a) hereof above (including Net Profit allocated to the Members under
     Section 9.1(a) hereof for such Fiscal Year) and this Section 9.1(b); and
     then

          (c) to the Members in proportion to their Percentage Ownership
     Interests.

     9.2 ALLOCATION OF SALE GAIN.  Any Sale Gain recognized by the Company in
any Fiscal Year shall be allocated in the following order of priority:

          (a) first, to the Members in an amount and in a manner so as to cause
     their Capital Accounts to be in proportion to their respective Percentage
     Ownership Interests; and

          (b) second, to the Members in proportion to their respective
     Percentage Ownership Interests as of the last day of such Fiscal Year (the
     "Last Day").

For purposes of this Section 9.2, the amount of a Member's capital account as
of a Last Day shall be computed as of such Last Day in the manner provided in
Section 7.4 hereof, but shall be adjusted to reflect the allocation to such
Member of all amounts required to be allocated to such Member for such Fiscal
Year under Article  9 hereof (other than pursuant to this Section 9.2).

     9.3 NET LOSS AND SALE LOSS.  The Company's Net Loss and any Sale Loss for
each Fiscal Year shall be allocated to the Members:

          (a) first in such amount and in such proportion as to cause their
     respective Capital Accounts to be in proportion to their respective
     Percentage Ownership Interests; and


                                     - 14 -


<PAGE>   29




          (b) thereafter, in proportion to their respective Percentage
     Ownership Interests.

     9.4 BOOK DEPRECIATION.  Book Depreciation and any other loss or deduction
(including loss on sale) with respect to ownership of the Company's assets
shall be included in the calculation of Net Income and Net Loss  provided,
however, that the Book Depreciation and any other loss or deduction (including
loss on sale) with respect to the following assets shall not be so included,
but shall be allocated in the manner indicated:

     (a) With respect to $60,000,000 of the MasterCard Purchased Assets, such
items shall be specially allocated to the Members in accordance with their Net
Earnings Interests until an Adjustment Event;

     (b) With respect to the National Data Group Contributed Assets, such items
shall be specially allocated to the Members in accordance with their Net
Earnings Interests until an Adjustment Event;

     (c) With respect to $50,000,000 of the MasterCard Purchased Assets, such
items shall be allocated to the Members in accordance with their Percentage
Ownership Interests until an Adjustment Event.

     9.5 SECTION 704(C) ALLOCATION.  Any items of income, gain, loss and
deduction with respect to any property that has been contributed by a Member to
the capital of the Company and which is required or permitted to be allocated
to the Members for income tax purposes under Section 704(c) of the Code so as
to take into account the variation between the tax basis of such property and
its agreed upon fair market value at the time of its contribution shall be
allocated to the Members solely for income tax purposes in accordance with the
traditional method set forth in Treasury Regulation Section  1.704-3(b) with
respect to contributions by MasterCard and the National Data Members and
otherwise by Approval of the Board of Directors.

     9.6 LIMITATION ON NET LOSS ALLOCATION.  Notwithstanding the provisions of
Section 9.3 hereof, if the amount of Net Loss and Sale Loss that would
otherwise be allocated to a Member in any Fiscal Year under Section 9.3 hereof
would cause (or increase) an Adjusted Capital Account Deficit for any Member as
of the Last Day of such Fiscal Year, then a proportionate part of such Net Loss
and Sale Loss equal to the sum of such Net Loss and Sale Loss, to the extent it
creates (or increases) such Member's Adjusted Capital Account Deficit, shall be
allocated to the other Member(s) to the extent possible.

     9.7 QUALIFIED INCOME OFFSET.  Notwithstanding any provision hereof to the
contrary, if any Member unexpectedly receives in any Fiscal Year any
adjustment, allocation or distribution described in Treasury Regulations
Section Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6), and if such Member has
an Adjusted Capital Account Deficit as of the Last Day of such Fiscal Year,
then all items of income and gain (including Sale Gain) of the Company
(consisting of a pro rata portion of each item of Company income and gain,
including gross income and Sale Gain) for such Fiscal Year (and, if necessary,
for subsequent Fiscal Years) shall be allocated to such Member in the amount
and in the manner necessary to eliminate such Adjusted Capital Account Deficit
as quickly as possible.

                                     - 15 -


<PAGE>   30



     9.8 GROSS INCOME ALLOCATION.  Notwithstanding any provision hereof to the
contrary, if a Member has an Adjusted Capital Account Deficit as of the Last
Day of any Fiscal Year, then items of income and gain (including Sale Gain) of
the Company (after taking into account allocations otherwise to be made to such
Member other than those provided in Section 9.7 and this Section 9.8) shall be
allocated to such Member in the amount and in the manner necessary to eliminate
such Adjusted Capital Account Deficit as quickly as possible.

     9.9 MINIMUM GAIN AND MEMBER MINIMUM GAIN CHARGEBACK.  Notwithstanding any
provision hereof to the contrary, any item of Company income or gain (including
Sale Gain) for any Fiscal Year (or any portion of any such item) that is
required to be allocated to the Members under Treasury Regulations Section
Section 1.704-2(f) or 1.704(2)(i)(4) shall be allocated to the Members for
such Fiscal Year (and, if necessary, for succeeding years) in the manner so
required by such Treasury Regulations.

     9.10 MEMBER NONRECOURSE DEDUCTIONS.  Except to the extent otherwise
allocated pursuant to Section 9.4, any item of Company loss, deduction or
expenditure described in Section 705(a)(2)(B) of the Code for any Fiscal Year
(or any portion of any such item) that is required to be allocated to the
Members under Treasury Regulation Section 1.704-2(i)(1) shall be allocated to
the Members in proportion to their respective allocations of Net Income or Net
Loss for such Fiscal Year.

     9.11 TARGET FINAL BALANCES.  The allocations of Net Profit, Net Loss, Sale
Gain and Sale Loss and the allocations in Section 9.4 of this Agreement are
intended to produce final Capital Account balances (Capital Account balances
immediately prior to the liquidation of the Company or of a Membership
Interest, after taking into account all allocations for fiscal periods through
such point in time) that are at levels ("Target Final Balances") that permit
liquidating distributions which, if made in accordance with such final Capital
Account balances would equal the distributions that would occur if such
liquidating proceeds were distributed in accordance with Percentage Ownership
Interests at that time.  To the extent that the allocation provisions of this
Agreement would not produce the Target Final Balances, the Members agree to
take such actions as are necessary to amend such allocation provisions to
produce such Target Final Balances.  Notwithstanding the other provisions of
this Agreement, allocations of income, gain, loss and deduction (including
items of gross income, gain, loss and deduction) shall be made to the maximum
extent possible to produce such Target Final Balances.

     9.12 TAX ALLOCATIONS.  Except to the extent otherwise provided
specifically in this Article 9, all items of Company income, gain, loss, and
deduction for federal, state, and local income tax reporting for any Fiscal
Year shall be divided among the Members in the same proportion as the sum of
items that are allocated to their respective Capital Accounts for the year are
divided.

                                   ARTICLE 10

                        DISTRIBUTION OF COMPANY PROPERTY

     10.1 ANNUAL DISTRIBUTIONS.  The Company shall distribute to the Members as
soon as possible following the close of a Fiscal Year (except in the year of a
Conversion in which case such distribution shall be made no later than
immediately prior to the Conversion) the following amounts in the following
order and priority:

                                     - 16 -


<PAGE>   31



           (a) For any period prior to an Adjustment Event, an amount equal to
      the Net Earnings of the Company shall be distributed to the Members in
      proportion to their respective Net Earnings Interests and any Net Cash
      Flow in excess of the Net Earnings shall be distributed to the Members in
      proportion to their respective Percentage Ownership Interests.  If
      Company does not have sufficient Net Cash Flow to make the foregoing
      distribution, to the extent such actual distributions are less than the
      required amount, the Company will be deemed to have made the distribution
      and to have borrowed the funds from the Members in accordance with
      Section 8.2.

           (b) For any period following an Adjustment Event, Net Cash Flow
      shall be distributed to the Members in proportion to their respective
      Percentage Ownership Interests.

The total amount distributed to the Members under paragraph (a) or (b) hereof
shall, with respect to each Fiscal Year, be no less than the total federal,
state and local income taxes that the Company would have paid if it had been a
corporation.

     10.2 NET SALES PROCEEDS.  Subject to the provisions of Section 23.2
hereof, Net Sales Proceeds shall be distributed by the Company to the Members
in the proportion to their respective Percentage Ownership Interests.

     10.3 CONSENT TO DISTRIBUTIONS.  All distributions provided for herein
shall be made only as and when determined by Approval of the Board of
Directors, consistent with the provisions of this Article 10.

     10.4 WITHHOLDING.  If the Code or applicable state law requires the
Company to withhold any tax with respect to a distributive share of Company
income, gain, loss, deduction or credit, or a distribution of cash or property,
the Company shall withhold and pay the tax.  If at any time the amount required
to be withheld exceeds the amount that would otherwise be distributed to the
Member to whom the withholding requirement applies, then that Member shall make
a contribution to the Company equal to the excess of the amount required to be
withheld over the amount, if any, that would otherwise be distributed to that
Member and which is available to be withheld.  Any amount withheld with respect
to a Member shall be deducted from the amount that would otherwise be
distributed to that Member but shall be treated as though it had been
distributed to such Member.

                                   ARTICLE 11

                             MANAGEMENT OF COMPANY

     11.1 BOARD OF DIRECTORS.  The management and control of the business
affairs of the Company shall be vested in the Members, which have chosen, as a
matter of administrative convenience, to exercise such management and control
through the Board of Directors, composed of one member designated by
MasterCard, three members (in the aggregate) designated by the National Data
Members, and such additional members as may from time to time be designated by
a Majority in Interest (the members of the Board of Directors being hereinafter
collectively referred to as the "Directors," and individually as a "Director");
provided, however, that (a) in no event shall the Board of Directors have fewer
than two (2) members and (b) until an IPO, no employee or director of a
Prohibited Transferee shall serve as a Director without first obtaining the
Approval of the Director designated by MasterCard; and provided further that
MasterCard shall not be entitled 

                                     - 17 -


<PAGE>   32



to appoint a Director after an IPO or after MasterCard owns less than the
Minimum Equity.  The foregoing restriction on the designation of an employee or
director of a Prohibited Transferee shall not apply to any person from and
after such person's retirement, resignation or other termination of services as
such employee or director of a Prohibited Transferee.  Each Member agrees that
the Director(s) appointed by such Member shall have the authority to act on
such Member's behalf to effectuate the purposes of this Agreement, to execute
documents on its behalf (unless such Member provides to the other Member(s)
prior written notice to the contrary) and, acting as a member of the Board of
Directors, to determine policy for the Company.  Directors serve solely at the
pleasure of the Member or Members appointing them and a Member or Members may
at any time and from time to time replace such Director(s).  Each Director
shall have the right to rely on the authority of the other Directors to act
hereunder until such time as the Director receives written notice that a
Director has been removed or his authority has been limited.  Each Member
entitled to designate a Director, by written notice to the other, may designate
an individual to serve as an alternate Director but each Director shall have
only one (1) vote on the Board of Directors, in connection with an Approval by
the Board of Directors under this Agreement.  No Director shall have the
authority to execute any instrument or bind the Company in any way without the
express Approval of the Board of Directors.

     11.2 INITIAL BOARD OF DIRECTORS.  The initial Board of Directors shall be
as follows:


     Director appointed by MasterCard:  William I Jacobs

     National Data Members:             Edward L. Barlow
                                        Neil Williams

     11.3 MEETINGS OF BOARD OF DIRECTORS.  Meetings of the Board of Directors
may be called by any Director on no less than 36 hours notice; provided,
however, that any Director may, within 24 hours of a called meeting, request a
delay in such meeting by up to 24 hours, and such delay shall be granted if it
is impractical for such Director to attend the meeting at the original time.
The Board of Directors may meet at any place within or without the State of
Georgia, as set forth in the notice of the meeting; a Director who is unable to
attend a meeting in person may attend at his election via telephone by
providing notice of such participation and the telephone number at which he can
be reached at least three (3) hours prior to such meeting.  Regular and special
meetings shall be held at any place designated from time to time by Approval of
the Board of Directors, including, but not limited to, meetings by telephone
conference call in which each participant is able to speak to and hear each
other participant.

     11.4 ACTION BY BOARD OF DIRECTORS.  Any action required herein to be
Approved or taken by the Board of Directors may be Approved or taken only upon
(a) Approval of the Board of Directors at a validly-held meeting, or (b)
through an executed written consent signed by all of the Directors specifying
the actions Approved and/or to be taken and such consent is filed in the minute
book of the Company.  Any such written consent shall be sent to each Director
as promptly as practicable.  Notwithstanding the provisions of . Section
14-11-308(b) of the Act, except as expressly limited by this Agreement, the
Board of Directors shall have the sole and exclusive right to manage and
control, and complete and exclusive discretion in the management and control
of, the affairs and business of the Company on behalf of the Members; and shall
have all of the rights and powers

      (n)  make any and all elections and decisions with respect to any
           federal, state, local or foreign tax or the reporting thereof.

Interest, shall be borne by the Company.

     11.6 RESTRICTIONS ON AUTHORITY OF BOARD OF DIRECTORS.

     (a)  Without the consent of each Member and except as otherwise
          expressly permitted herein, the Board of Directors may not:

             (i)   do any act in contravention of this Agreement;

             (ii)  possess property, or assign rights in specific
                   property, for other than a Company purpose; or

             (iii) knowingly perform any act that would subject
                   any Member to liability for the obligations of the Company in
                   any jurisdiction.

      (b)  Without the consent of a Majority in Interest and MasterCard

           Member), the Board of Directors may not:

             (i)   amend the Articles or this Agreement except to

                   action (including without limitation canceling such
                   agreements) if the effect of such amendment or other action
                   would be to adversely affect the benefits and protections

      (c)  Without the consent of a Majority in Interest and except as
           otherwise expressly permitted herein, the Board of Directors may
           not:

             (i)   do any act which would (A) make it impossible
                   to carry on the ordinary Business of the Company or (B)
                   change the Business of the Company;

             (ii)  dissolve and liquidate the Company except in accordance with
                   Article 23;

             (iii) merge the Company;

                   or

             (v)   admit new members to the Company and amend the
                   Articles and/or the Agreement to reflect such admissions.

     11.7 VOTING RIGHTS OF MEMBERS.  Except as provided in Section 11.6(a) of
this Agreement, the consent of a Majority in Interest is required to take any
action or give any Approval as Members including, but not limited to, any of
the actions listed in Section 14-11-308(b) of the Act.  The Members expressly
agree that unanimous approval of Members is not required for the actions in
Section 14-11-308(b) of the Act.

     11.8 AUTHORITY OF MEMBERS; MEETINGS; ACTION BY MEMBERS WITHOUT A MEETING.
Members shall have no authority to execute any instrument or bind the Company
in any way without the express Approval of a Majority in Interest.  A meeting
of Members shall be called by the Directors whenever they deem necessary or by
any Member.  Any such meeting shall be held at the principal place of business
of the Company, or at such other location as the Members may mutually agree,
and may be held in person or by telephonic conference call in which each
participant can speak to and hear each other participant.  The Board of
Directors or the Member shall send each Member a written notice of each
meeting, stating the time, date, place and purpose of the meeting, not less
than five (5) days before the scheduled date of such meeting.  Action required
or permitted to be taken at a meeting of Members may be taken without a
meeting if the action is evidenced by one or more written consents describing
the action taken, signed by a Majority in Interest or such other vote as may be
required pursuant to Section 11.6 and delivered to the Secretary or other
person designated by the Members for inclusion in the minutes or for filing
with the Company records.  Any such consent shall be sent to each Member as
promptly as practicable.  Action taken under this Section 11.8 is effective
when a Majority in Interest, or all Members, as the case may be, has signed the
consent, unless the consent specifies a different effective date.  The record
date for determining Members entitled to take action without a meeting shall be
the date the first Member signs a written consent.

     11.9 WAIVER OF NOTICE.  When any notice is required to be given to any
Director or Member, a written waiver of notice signed by the Member or Director
entitled to such notice, whether before, at, or after the time stated in the
notice, shall be equivalent to the giving of such notice.

     11.10 OFFICERS.  The Board of Directors is hereby authorized by the
Members to appoint Officers by resolution to implement the decisions of the
Board of Directors, including, but not limited to, the administration of the
day-to-day business of the Company, and, subject to the terms of Section 11.7
hereof and the other provisions of this Agreement, the administration of the
ordinary and usual business affairs of the Company, except as expressly limited
by this Agreement, 

                                     - 21 -


<PAGE>   36



and the Officers so appointed shall be responsible for such
implementation.  Except as expressly provided to the contrary in this
Agreement, and except as otherwise directed by the Board of Directors, the
Officers are authorized to make decisions relating to the day-to-day affairs of
the Company and to implement such decisions.  In addition, the Board of
Directors is hereby authorized to delegate to the Officers such
responsibilities as deemed appropriate by Approval of the Board of Directors,
including, but not limited to, the right to execute and deliver instruments on
behalf of the Company.

     11.11 REMOVAL OF OFFICERS.  Any of the Officers may be removed by Approval
of the Board of Directors, by written notice of such removal given without any
prior notice or warning, for any reason whatsoever, and the Board of Directors
shall appoint such Officer's successor.

     11.12 COMPENSATION FOR SERVICES.  No Member or Affiliate of any Member
shall receive any compensation from the Company for its services as a Member of
the Company without having first obtained the Approval of the Board of
Directors for the payment of any such compensation by the Company.
Compensation of Officers shall be as Approved by the Board of Directors.

     11.13 LIABILITY OF THE MEMBERS, OFFICERS AND DIRECTORS.  As long as a
Member, an Officer or a Director, as applicable, shall act in good faith with
respect to the conduct of the business and affairs of the Company, no such
Member, Officer or Director shall be liable to the Company or to the Members,
in damages or otherwise, for any error of judgment, for any mistake of fact or
of law, or for any other act or thing which such Member, Officer or  Director,
as applicable, may do or refrain from doing in connection with the business and
affairs of the Company, except in the case of gross negligence, willful
misconduct, fraud or bad faith.

     11.14 INDEMNITY.  The Company does hereby agree to indemnify and to hold
the Officers, the Directors, and the Members wholly harmless from any loss,
expense or damage suffered by any Officer, Director or Member by reason of
anything such Officer, Director or Member, as applicable, may do or refrain
from doing hereafter for and on behalf of the Company and in furtherance of its
interests to the extent authorized hereunder; provided, however, that the
Company shall not be required to indemnify any Officer, Director or Member for
any loss, expense or damage which such Officer, Director, or Member, as
applicable, might suffer as a result of such Officer's, Director's or Member's,
as applicable, gross negligence, willful misconduct, fraud or bad faith.

                                   ARTICLE 12

                           RELATED PARTY TRANSACTIONS

     Except as otherwise provided in this Article 12 and elsewhere in this
Agreement, any of the Members or their Affiliates may engage in transactions
with the Company in addition to those contemplated by this Agreement (an
"Affiliate Transaction"), provided, that each Member shall, in good faith,
cause the transaction with the Company to be on a commercial arm's length
basis, and the Board of Directors shall not permit or Approve any such
transaction, including but not limited to any transaction involving matters
affecting the working capital of the Company, unless it shall have determined
that the transaction satisfies the foregoing requirement and is in the best
interest of the Company and the Members, provided, however, that the foregoing
obligations shall not apply to MasterCard with respect to transactions not
involving MasterCard or any of its Affiliates.  In determining whether a
particular transaction with the Company satisfies the criteria of this Article
12, all aspects of such transaction and all facts and circumstances surrounding
such 

                                     - 22 -


<PAGE>   37



transaction taken together (and if such transaction is one of a series of
related transactions, including pursuant to any pre-established contract or
arrangement, then all of such related transactions, and the terms of such
contract or arrangement) shall be taken into account.  In the event that a
Member reasonably believes that any Member has entered into an Affiliate
Transaction with the Company that does not comply with the foregoing
provisions, such Member shall have the right to submit the question to
Arbitration as provided in Article 22.  Notwithstanding anything to the
contrary contained in Section 11.8, MasterCard shall have the right to enforce
on behalf of the Company any and all agreements between the Company and any
Entity in the National Data Group (or any Affiliate thereof) including, without
limitation, the Purchase Agreement, the NDCI Service Agreement and the Software
License Agreement.  The rights granted to MasterCard under this Article shall
cease to exist upon the first to occur of (a) an IPO or (b) MasterCard's having
less than the Minimum Equity.


                                   ARTICLE 13

                                    BANKING

     The funds of the Company shall be kept in one or more separate bank
accounts in the name of the Company in such banks or other federally-insured
depositories as may bed by the Board of Directors, or shall otherwise be
invested in the name of the Company upon such terms and conditions as Approved
by the Board of Directors from time to time.  All withdrawals from any such
bank accounts or investments established by the Company hereunder shall be made
on such signature or signatures as may from time to time be Approved by the
Board of Directors.

                                   ARTICLE 14

accurate books of account at such locations as may receive Approval of the

maintained, and its income, gains, losses and deductions shall be determined
and accounted for in accordance with GAAP and using the methods Approved by the
Board of Directors.

after the close of each Fiscal Year, GPS, at the expense of the Company, shall
have a full audit and financial statements of the Company for such Fiscal Year
prepared and distributed to the Members.  Such financial statements and audit
results shall be prepared by the Company and shall be true and correct, shall
be certified in the customary manner by a so-called "Big Six" firm of
independent certified public accountants as may be Approved by the Board of
Directors, shall be in accordance with the Board of Directors' requirements and
specifications therefor, and shall include an income and expense statement and
balance sheet which shall reflect the results of the operations of the Company
for such Fiscal Year, the financial condition of the Company, and all other
information customarily reflected in financial statements prepared in
accordance with generally-accepted accounting principles.  Within forty-five
(45) days after the end of each quarter, the Company shall also have prepared
and delivered to each  Member (a) a profit and loss statement and Company


                                     - 23 -


<PAGE>   38



balance sheet, and a comparison to the income and expenses of the Company
through the previous calendar quarter, and (b) a cash flow statement, setting
out current quarter and year-to-date figures.

     14.4 INCOME TAX RETURNS.  Following the close of each Fiscal Year, the
Company shall have prepared and delivered to each Member, at the expense of the
Company, information with respect to the business transactions of the Company
for such Fiscal Year in sufficient detail to enable each Member to prepare such
Member's federal, state and local income tax returns in accordance with all
then applicable laws, rules and regulations.  The Company shall also cause any
federal, state or local income tax returns to be prepared and submitted  for
review and Approval of the Board of Directors prior to the due date thereof (as
the same may be extended), and following appropriate modifications and final
approval thereof shall cause the same to be properly filed.  The Members
acknowledge and agree that the Company is a partnership for income tax
purposes, and that they shall file tax returns and otherwise conduct their
affairs in a manner consistent with such characterization.

     14.5 TAX MATTERS PARTNER.  GPS shall be the "Tax Matters Partner" for Code
purposes and shall notify the Members promptly of any tax audit or other tax
examination or determination of which it is notified materially affecting the
Company or the Members and shall provide any Member upon request copies of all
notices or communications with respect thereto.  GPS specifically shall have
the power to (a) extend the statute of limitations or any period of limitations
with respect to the Company in any matter; (b) agree to any settlement of any
tax matter affecting the Company, (c) file any petition for judicial review, or
any other judicial proceeding with respect to the Company in any matter; or (d)
file any requests for administrative review or adjustment, or other
administrative relief, on behalf of the Company, in any matter.

                                   ARTICLE 15

                           CONVERSION OF THE COMPANY

     At any time on or after Closing, GPS may request a Conversion.  Upon such
request, GPS and the Board of Directors shall prepare and GPS shall have the
right to require the Company and any of its Members to execute and deliver any
agreements, instruments or other documents reasonably required by GPS to
consummate the Conversion.  The articles of incorporation, bylaws and
organizational minutes of the surviving corporation shall be Approved by GPS.
Each Member agrees that it will execute and deliver all such agreements,
instrument and documents as are required, in the reasonable judgment of GPS, to
be executed by such Member in order to consummate the Conversion, provided
those documents otherwise satisfy all the requirements of this Agreement.

     Upon consummation of a Conversion, each Member will be entitled to receive
that number of shares of stock of the surviving corporation obtained by
multiplying the total number of shares of common stock to be issued by the
surviving corporation in connection with the Conversion by the Percentage
Ownership Interest held by such Member as of the date of Conversion.  Such
Member's Percentage Ownership Interest may be changed immediately prior to the
Conversion pursuant to Article 20.  In addition, the surviving corporation will
assume all of the outstanding debt and other liabilities of the Company.  No
Member shall be subject to any obligations in any way permitting, restricting
or limiting its ability to participate fully in such Conversion.  Except as the
provisions of this Agreement specifically state otherwise, all rights,
protections and benefits of the Members 


                                     - 24 -


<PAGE>   39


under this Agreement shall continue to be available to them in their capacity
as stockholders of the surviving corporation.  Further, the articles of
incorporation and bylaws of the surviving corporation shall incorporate the
governance and other operating provisions of this Agreement and a shareholders'
agreement shall incorporate the various rights, protections and benefits
provided to a Member by this Agreement, including but not limited to the rights
provided for in Articles 20 and 21 hereof, except to the extent expressly
waived in writing by the Member or Members entitled to such right, protection
or benefit.

     The Members acknowledge that a Conversion may be undertaken in connection
with other events, such as an IPO, an acquisition of another business or Entity
or the sale of equity in the surviving corporation to other persons and that
such Conversion shall be deemed completed immediately prior to any such event.


                                   ARTICLE 16

                        ADMISSION OF ADDITIONAL MEMBERS

     Subject to and except as otherwise provided in Article 18, no additional
Entity shall be admitted to the Company as a Member (whether as a result of
issuance of new Membership Interests or transfers of existing Membership
Interests) without the Approval of the Board of Directors and Approval of a
Majority in Interest.  Any adjustment to the Membership Interests of the Member
that may occur as a result of the issuance of new Membership Interests when
admitting another Entity to the Company as a Member shall be shared by all
Members on a pro-rata basis according to such Member's Percentage Ownership
Interest.


                                   ARTICLE 17

                                  WITHDRAWALS

     Each of the Members does hereby covenant and agree that such Member will
not withdraw or retire from the Company except as the result of a permitted
transfer of such Member's entire interest in the Company pursuant to Article
18, 20 or 21 hereof, and that such Member will otherwise carry out such
Member's duties and responsibilities hereunder until the Company is dissolved
and liquidated pursuant to Article 23 hereof.


                                   ARTICLE 18

                        TRANSFER OF MEMBERS' INTERESTS;
                        ADMISSION OF ADDITIONAL MEMBERS

     18.1 TRANSFERS OF MEMBERS' INTERESTS.  Each of the Members hereby
covenants and agrees that such Member will not at any time sell, assign,
transfer, mortgage, pledge, encumber, hypothecate or otherwise dispose of all
or any part of such Member's interest (excluding, however, such Member's right
to distributions hereunder, if such Member otherwise retains its status as a
Member) in the Company to any Entity, other than pursuant to the following
provisions of this Section 18.1 or the applicable provisions of Article 20 or
21 hereof, without first having obtained the Approval of any such proposed
disposition from a Majority in Interest of the other Members 


                                     - 25 -


<PAGE>   40




(excluding Affiliates) and without having complied with all applicable federal
and state securities laws.  Notwithstanding the foregoing, a Member other than
GPS may assign or otherwise transfer all or any part of such Member's
Membership Interest in the Company to an Affiliate of such Member or by
operation of law (any such transfer being deemed "Approved" for purposes of the
remaining provisions of this Section 18.1).  Any transfer in excess of those
permitted under the preceding two sentences must be approved by a Majority in
Interest of the Members that are not Affiliates of the Member making the
transfer. Following a Conversion or an IPO, all of the foregoing restrictions
on transfer shall terminate.  Any Member seeking to transfer solely the
economic portion of its Membership Interest (including a Member seeking to
transfer its Membership Interest under the applicable provisions of Article 21)
may do so without such approval and any transferee of such rights shall not be
considered a Member. In order to effectuate any assignment or transfer of a
Member's interest in the Company to any Entity which is Approved hereunder to
be admitted as a Member in the Company as permitted under this Section 18.1,
the retiring Member shall require any such assignee or transferee to accept in
writing all of the applicable terms of this Agreement and may require such
assignee or transferee to execute any other instruments and agreements and pay
any fees desired by the retiring Member.  The remaining Member(s) agree(s), at
the retiring Member's request, to join with the retiring Member and any such
assignee or transferee in the execution of an amendment to this Agreement
admitting such assignee or transferee as a Member and, if only a portion of the
retiring Member's interest in the Company is being transferred, modifying such
terms hereof as are reasonably necessary to allocate, between the retiring
Member and such assignee or transferee, such of the retiring Member's rights
and obligations hereunder as the retiring Member wishes to allocate.  The
foregoing procedure for effectuating transfers or assignments of the retiring
Member's interest in the Company and the substitution or admission as a Member
of the Company of such transferees or assignees shall apply to all such
transfers, substitutions and admissions, but shall have no effect after an IPO
or with respect to any stock of a corporation into which the Company may be
converted pursuant to Article 15.  The foregoing restrictions have no
application to any new Membership Interests in the Company that are issued
pursuant to the terms of this Agreement except and to the extent this Article
is made to apply to such Membership Interests after they have been issued by
Approval of the Board of Directors and a Majority in Interest.  The Members
agree that, until an IPO, no Membership Interest or a Member's right to
distributions under this Agreement will be transferred to a Prohibited
Transferee without the Approval of MasterCard provided MasterCard is then a
Member or to a competitor of the Company without the Approval of a Majority in
Interest.  NDC agrees that, until an IPO, NDC shall not cause of permit any
Prohibited Transferee to Beneficially Own any equity or debt security of any
Entity which is controlled by NDC (but specifically excluding NDC itself), such
that as a result of such Beneficial Ownership such Prohibited Transferee would
Beneficially Own any Membership Interest, provided MasterCard is then a Member.

     18.2 SECTION 754 ELECTION.  In the event of a transfer of all or part of a
Member's interest in the Company, the Company shall elect, at the request of
any existing Member or any person being admitted as a Member, to adjust the
basis of the Company's assets pursuant to Section 754 of the Code or the
corresponding provision of subsequent law.  In the case of a newly-admitted
Member, the election shall be filed by the Company as constituted prior to such
admission.  The transferee of the Membership Interest shall pay all costs of
preparing and filing such election and for any increased accounting costs
thereafter attributable to such election.

                                    DAMAGES

     Any payment of a damage, loss, liability, tax or expense (including
without limitation reasonable expenses of investigation and reasonable
attorneys' fees and expenses in connection with any action, suit or proceeding)
(collectively referred to herein as "Damages") incurred or suffered by the
Company with respect to the National Data Group Contributed Assets, or the
MasterCard Contributed Assets or the MasterCard Purchased Assets arising out
of, or attributable to, any misrepresentation or breach of warranty, covenant
or agreement made or to be performed by either Member pursuant to the Purchase
Agreement shall not be treated as a transaction between a partner and a
partnership.  Notwithstanding the foregoing, in the event any National Data
Member or MasterCard fails to pay for any Damages in accordance with its
obligations under the Purchase Agreement, the amount of such Damages may be
withheld from any amount otherwise distributable or payable to such Member
hereunder.

     20.1 PUT RIGHT.  At any time after the Closing of the Purchase Agreement
and from time to time, but not sooner than the earlier of (a) four (4) years
after the date hereof, (b) a Change in Control of the Company, or (c) a knowing
or intentional Breach of this Agreement by any National Data Member (a "Put
Event") (and no later in the case of clause (a) than the earlier of six (6)
years after the date hereof or the completion of an IPO and no later in the
case of clause (c) than the completion of an IPO), MasterCard may put to the
Company ("Put Right") all or any portion of its Membership Interest in the
Company (the "Put Equity").  In addition, an IPO shall be a Put Event for up to
fifty percent (50%) of MasterCard's Membership Interest; and three (3) years
after the date hereof without an IPO having occurred (but ending this Put Event
with the earlier of an IPO or six (6) years after the date hereof) shall be a
Put Event for up to fifty percent (50%) of MasterCard's Membership Interest,
provided MasterCard must retain the Minimum Equity after the exercise of any
and all such Put Rights with respect to the Put Events in this sentence.

     20.2 EXERCISE OF PUT RIGHT.  MasterCard's Put Right  shall be exercised
("Put") by providing the Company with notice (the "Put Notice") specifying (i)
the percentage of its Membership Interest to be put; (ii) the date on which the
Put Price (as hereinafter defined) is to be paid (the "Put Date"); and (iii)
the proposed Put Price.  The Put Notice shall be given at least ninety (90)
days in advance of a Put Date.  If the event is an IPO, the Put Price shall be
due at the initial closing pursuant to the IPO.  MasterCard may not exercise
more than two (2) Puts during any twelve (12) month period.

     20.3 DETERMINATION OF PUT PRICE.  If a Put Event occurs, the value of
MasterCard's Membership Interest (the "Put Price") shall be determined as
follows:

           (a) in the event of an IPO by the Company, or its successor after a
      Conversion, that is a Put Event, the Put Price shall be the initial IPO
      price per share, less Registration Expenses per share that would be
      payable by MasterCard pursuant to the Registration Rights Agreement of
      even date herewith if MasterCard were to sell its Put Equity in the IPO,
      including, but not limited to, any underwriters' commissions or

                                     - 27 -


<PAGE>   42


      discounts, all as reflected on the cover page of the final prospectus of
      the IPO,  times the number of shares that MasterCard would have been
      entitled to receive for the Put Equity in the Conversion; and

           (b) in any other event, that is a Put Event, the Put Price shall be
      approved by MasterCard and GPS, or failing such approval shall be
      determined by an appraiser appointed by agreement between MasterCard and
      GPS.  If there is no agreement upon a single appraiser within thirty (30)
      days after notice of the Put Event, the Put Price shall be determined by
      the majority vote of a board of three (3) appraisers, GPS appointing one
      (1) appraiser, MasterCard appointing one (1) appraiser and the two
      appointed appraisers appointing the third appraiser.  If either of the
      two appraisers is not so appointed or if the two appraisers refuse or
      fail to appoint the third appraiser within thirty (30) days after notice
      of the Put Event, either MasterCard or GPS may request the American
      Arbitration Association to make the appointments in default in accordance
      with its rules then obtaining and the parties shall abide by any
      appointment so made.  The appraisers shall determine the value of the Put
      Equity based on the fair market value of the Company on a stand alone
      basis without regard to the rights of any controlling person multiplied
      by the Percentage Ownership Interests in the Put Equity.  The costs of
      the appraisal shall be borne equally by MasterCard and the Company.  The
      Put Date shall be extended to such time after completion of the appraisal
      as MasterCard may reasonably designate.

           (c) MasterCard may withdraw a Put if the Put Price determined by the
      appraisal is not satisfactory to MasterCard.

     20.4 PAYMENT OF PUT PRICE.  On the Put Date, upon delivery to the Company
of Certificates representing the Put Equity, which instrument shall contain a
full warranty of title, to the effect that MasterCard has good and marketable
title to the Put Equity free and clear of all claims and encumbrances (other
than the restrictions created by or provided for in this Agreement), and such
other instruments as the Company may reasonably request, the Company shall pay
to MasterCard or its designee the Put Price in cash for the Put Equity so
delivered.  If the Put Event is an IPO, the Put Price (payable in cash) shall
be due at the initial closing pursuant to the IPO.

     20.5 TERMINATION OF PUT .  All Puts and Calls shall terminate at an IPO
except the Put Right provided with respect to the Put Event related to a Change
In Control, which shall terminate and be of no further force and effect at any
time that (a) MasterCard no longer has any equity interest in the Company or
its successor after a Conversion, (b) MasterCard's equity interest in the
Company or its successor after a Conversion is tradable in an established
market without restrictions pursuant to the federal securities laws, or (c) the
aggregate interest of the National Data members in the Company or its successor
after a Conversion becomes less than a Majority in Interest as a result of any
IPO.  In addition after an IPO, but before the earlier of (i) MasterCard's
having the right to cause its equity interest in the Company or its successor
after a Conversion to be registered under the Registration Rights Agreement, or
(ii) MasterCard's equity interest in the Company or its successor after a
Conversion is tradable in an established market without restrictions pursuant
to the federal securities laws, if the Company or its successor after a
Conversion permits an employee or director of a Prohibited Transferee to become
a Director without the Approval of MasterCard, MasterCard will be entitled to
treat such permission as a Put Event with respect to its remaining equity
interest in the Company or its successors after a Conversion and to exercise
its Put Right in respect thereof, but any such Put Right must be exercised
within 90 days of such Put Right becoming known to MasterCard.

                                   ARTICLE 21

               RIGHT TO COMPEL SALE; RIGHT TO PARTICIPATE IN SALE

     21.1 OBLIGATION TO SELL.  If the National Data Members, in the aggregate
and as part of a single transaction, should sell any of their Membership
Interests in a bona fide transaction to any Third Party, or if National Data,
in the aggregate and as part of a single transaction, should sell issue or
cause or permit to be issued any equity or debt securities of any Entity which
is controlled by NDC (but specifically excluding NDC itself and the Company),
such that, as a result of such sale(s) or issuance(s), the Third Party would,
together with such Third Party's Affiliates, Beneficially Own directly or
indirectly, more than 50% of the Membership Interests in the Company and on
terms such that no National Data Member retains any direct or indirect
beneficial interest in or option or right over the Membership Interest(s) being
disposed of other than as a bona fide creditor with a bona fide security
interest therein and that National Data does not retain any direct or indirect
beneficial interest in or option or right over the securities being sold or
issued other than as a bona fide creditor with a bona fide security interest
therein (a "Sale"), the National Data Members may, at their option, except as
set forth below in Section 21.3, require MasterCard to participate in such
Sale.  National Data shall provide written notice of such Sale to MasterCard
("Sale Notice").  The Sale Notice shall identify the purchaser, the amount of
Membership Interest, the consideration for which a sale is proposed to be made
(the "Sale Price") and all other material terms and conditions of the Sale.
MasterCard shall be required, as set forth below, to tender a percentage of its
respective Percentage Ownership Interest equal to the percentage of the
aggregate Percentage Ownership Interests of all of the National Data Members
that the National Data Members intend to sell. MasterCard shall cooperate with
the representative of the National Data Members designated in the Sale Notice
and shall deliver all documents the representative may reasonably request that
may be required to be executed in connection with such Sale.  A transfer under
this Article 21 is subject to the provisions of Section 18.1 and any transfer
made hereunder without the Approval therein required shall be a transfer solely
of the economic portion of such Membership Interest, and references in this
Article 21 to Membership Interest in such context shall be a reference solely
to such economic portion, the remaining rights of such Membership Interest
continuing to reside in the transferring Member.

     21.2 RIGHT TO PARTICIPATE IN SALE.   For purposes of this Section 21.2
(and the corresponding provisions of the remaining Sections of this Article
21), the requirement in the definition of "Sale" in Section 21.1 that the sale
or issuance of equity or debt securities in any Entity controlled by NDC be "as
a part of a single transaction" shall not apply prior to a Conversion.  If the
National Data Members should participate in a Sale, National Data shall give
MasterCard a Sale Notice and MasterCard shall have the right and option,
exercisable as set forth below, to participate in such Sale pro rata in
accordance with its respective Membership Interests based on Percentage
Ownership Interests in the Company in the Sale, in which event the Membership
Interest(s) or the securities to be sold by the National Data Members or
National Data, as the case may be, in the Sale shall be reduced to the extent
MasterCard elects to participate and such reduction is required.  Within
fifteen (15) business days after the date the Sale Notice is given, MasterCard
shall provide National Data with written irrevocable notice authorizing
National Data to sell or otherwise dispose of MasterCard's Membership Interest
pursuant to the terms of the Sale.  Delivery of such notice authorizing
National Data to sell or otherwise dispose of such Membership Interests shall
constitute an irrevocable acceptance of the Sale on the terms set forth in the
Sale Notice. After delivery of such notice, MasterCard shall not be entitled to
participate in the sale of Membership Interests pursuant to the Sale if it does
not execute any 

                                     - 29 -


<PAGE>   44


agreements, certificates or other documents required to consummate the transfer
of the Membership Interests pursuant to this Section. If MasterCard shall have
elected not to participate in the Sale, (i) MasterCard will be deemed to have
waived any of and all of its rights under this Section 21.2 with respect to the
sale or other disposition of its Membership Interests pursuant to the Sale, and
(ii) the National Data Members or National Data, as the case may be, shall have
ninety (90) days from the date the Sale Notice is given in which to sell the
applicable Membership Interests or securities on terms no more favorable to the
National Data Members or National Data than those set forth in the Sale Notice,
and in no event at a price higher than that contained in the Sale Notice. 
MasterCard's sole remedy for a Breach of this provision is to exercise its Put
Right pursuant to Section 20.1(c).

     21.3 CONSIDERATION.  The consideration to be paid to the National Data
Members or National Data, as the case may be, and MasterCard in a Sale shall be
their respective share of the Sale Price based upon their respective
percentages of the Membership Interests based on Percentage Ownership Interests
included in the Sale.  In the event the consideration to be paid pursuant to
the Sale is (a) other than cash, debt or Marketable Securities or (b)
marketable securities of a Prohibited Transferee, unless MasterCard agrees to
participate in the Sale, the Company shall be obligated to pay MasterCard's
share of the Sale Price to MasterCard in cash.  If MasterCard receives cash
hereunder, it shall be entitled to use the appraisal procedure with respect to
the consideration received by the National Data Members or National Data as set
out in Section 20.3(b) (except that the value shall be the fair market value of
the consideration received by the National Data Members and shall not be the
value of the Company) to determine its appropriate amount of cash.  "Marketable
Securities" are securities traded on NASDAQ or a national securities exchange
or any comparable successor markets for public trading of securities if the
number of shares traded in such markets are sufficiently large to permit
MasterCard to dispose of its shares reasonably promptly after closing and any
holding period for pooling of interest accounting without materially adversely
affecting the market price for such shares.  The provisions of this Section
21.3 are applicable to the consideration payable to MasterCard in any sale of
its Membership Interest in connection with any merger of the Company with, or
sale of all or substantially all of the assets or Membership Interests of the
Company to, another Entity, and none of the rights, protections, benefits or
obligations in this Agreement with respect to Members, including MasterCard and
the National Data Members, shall be applicable after a transaction referred to
in this sentence.

     21.4 WITHDRAWAL FROM SALE.  If, within one hundred twenty (120) days after
National Data gives the Sale Notice, the sale of all the Membership Interests
subject to the Sale has not been completed, any Member shall be entitled to
withdraw its Membership Interest from such Sale and National Data shall not be
permitted to require MasterCard to include its Membership Interest in any Sale
without again complying with the provisions of this Section.  Notwithstanding
anything contained in this Article 21 to the contrary, there shall be no
liability on the part of the National Data Members or National Data to
MasterCard if the Sale of the Membership Interests or securities pursuant to
Section 21.1 or 21.2 is not consummated for whatever reason.  Any decision as
to whether to sell Membership Interests shall be within  the sole and absolute
discretion of National Data.

     21.5 PARTICIPATION BY MASTERCARD.  MasterCard shall have the right to
participate in the closing for the Sale and to inspect all documents executed
in connection therewith.  Promptly after the consummation of the Sale of the
Membership Interests of the National Data Members and MasterCard pursuant to
this Article 21, the National Data Members shall remit or cause to be remitted
to MasterCard the total consideration for its Membership Interest sold pursuant
thereto as computed pursuant to this Article 21, and shall furnish such other
evidence of the completion and 

                                     - 30 -


<PAGE>   45


time of completion of such sale or other disposition and the terms thereof as
may be reasonably requested by MasterCard.

     21.6 PRIORITIES AND TERMINATION.  If at any time after notice of a Sale
has been given to MasterCard hereunder in good faith, the contemplated Sale
involves a pooling of interest accounting and a tax free transaction with
respect to the securities serving as consideration in the Sale, exercise of the
Put Right could cause the Sale not to qualify for such accounting and  the Sale
is proceeding to completion in a diligent manner and in good faith, MasterCard
shall not be entitled to a Put, provided that this prohibition shall not extend
for longer than 90 days after receipt of such Sale notice plus such reasonable
time (not to exceed an additional 90 days) as may be necessary to get any
regulatory or stockholder approvals that are required for the Sale.  In the
event MasterCard is prevented from exercising its Put Right because of a
proposed Sale during the period commencing on the fifth (5th) anniversary and
ending on the sixth (6th) anniversary hereof and the Sale does not occur, the
six year limit for exercising the Put Right shall be extended for the period
during which MasterCard was prevented from exercising the Put Right pursuant to
this section  The provisions of this Article 21 shall terminate and have no
further force and effect upon an IPO.


                                   ARTICLE 22

                                  ARBITRATION

     22.1 LOCATION AND GOVERNING RULES.  Any dispute arising out of or in
connection with this Agreement, including any question regarding its existence,
validity or termination, shall be referred to and finally resolved by
arbitration in Washington, D.C. under the Rules of Commercial Arbitration (the
"Rules") of the American Arbitration Association (the "AAA"), which Rules are
deemed to be incorporated by reference into this Section 22.1.  Judgment upon
the award rendered by the arbitrators in any such arbitration may be entered in
any court having jurisdiction thereof.  Except as the arbitrators may otherwise
award or assess the expenses of any such arbitration and except as otherwise
provided in this Agreement, each party shall bear its own costs and expenses,
including the expense of its counsel.  The parties agree that service of any
notice in the course of any such arbitration at their respective addresses for
notice and in the manner provided in Section 24.2 of this Agreement shall be
valid and sufficient notice for purposes of such arbitration.

Article 22, the award shall be rendered by a majority of the members of a board
of arbitration consisting of three members.  One arbitrator shall be appointed
by a party to the dispute and one arbitrator shall be appointed by the other
party to the dispute within sixty (60) days after the commencement of the
arbitration proceeding.  The third arbitrator shall be appointed by mutual
agreement of the two selected arbitrators and shall be experienced in corporate
contractual matters relating to transactions of the nature contemplated by this
Agreement.  In the event of the failure of said two arbitrators to agree as to
the third arbitrator within sixty (60) days after the appointment of the last
of the two arbitrators, the third arbitrator shall be appointed by the
Washington, D.C. office of the AAA in accordance with its then-existing rules.
Notwithstanding the foregoing, in the event that either party shall fail to
appoint the arbitrator it is required to appoint within the specified time
period, such arbitrator and the third arbitrator shall be appointed by the
Washington, D.C. office of the AAA in accordance with its then-existing rules.
For purposes of this Section 22.2, the commencement of the arbitration
proceeding shall be deemed to be the date upon which a written demand for
arbitration is received by the Washington, D.C. office of the AAA from one of
the parties.

attached to this letter as Appendix 1.  Capitalized terms used in this opinion
letter and not otherwise defined herein shall have the meanings assigned to
such terms in the Interpretive Standards or the Agreement.

     In the capacity described above, we have considered such matters of law

the due execution and delivery of all documents where due execution and
delivery are prerequisites to the effectiveness thereof.

factual matters upon the representations and warranties contained in
certificates and statements of officers and representatives of NDC and certain
public officials and upon the accuracy and completeness of the representations
and warranties of the parties to the Agreement.  We have made no independent
investigations with regard thereto and, accordingly, do not express any view or
belief as to matters that might have been disclosed by independent
verification.

     The opinions set forth herein are limited to the laws of the State of

          3. The Company has duly authorized the execution and delivery
     of the Transaction Agreements and all performance by the Company
     thereunder and has duly executed and delivered the Transaction
     Agreements.

          4. No consent, approval, authorization or other action by, or

     Agreement and the Newco Assignment and Assumption Agreement are

     THIS SUBLEASE AGREEMENT ("Sublease") is made this _____ day of _______,
1996 between NDC International Ltd. ("Sublandlord"), and Global Payment Systems
LLC, a Georgia limited liability company ("Subtenant").

                              R E C I T A L S:

     WHEREAS, Commission for the New Towns as Landlord ("Prime Landlord") and
Sublandlord, as Tenant did enter into a certain Lease (together with any
certain amendments or modifications thereof, the "Prime Lease"), dated
_________, for the lease by Sublandlord of certain space (the "Sublandlord's
Premises") more particularly described in the Prime Lease and located in Prime
Landlord's building (the "Building") known as Peterscourt Building, Peterscourt
City Road, Peterborough, Cambridgeshire, England.  Sublandlord and Subtenant
desire to enter into this Sublease, pursuant to which Subtenant will lease from
Sublandlord, and Sublandlord will lease to Subtenant, a portion of
Sublandlord's Premises.

     NOW THEREFORE, for and in consideration of the mutual covenants and
obligations:

     1. SUBLEASED PREMISES.  Sublandlord does hereby lease to Subtenant, and
Subtenant leases and rents from Sublandlord, up to 90% of the Sublandlord's
Premises (the "Subleased Premises").  The Subleased Premises are being leased
by Sublandlord to Subtenant in their condition existing on the date hereof "AS
IS", and Sublandlord shall not be obligated to construct any demising walls or
make any improvements whatsoever with regard to the Subleased Premises.
Subtenant shall be obligated to construct any demising walls necessary on the
Subleased Premises at its own expense and cost.

     This Sublease shall also include all of the furniture, fixtures, equipment
and improvements thereon located on the Subleased Premises owned by
Sublandlord.

     2. TERM.  The term of this Sublease shall commence on the date first above
written (the "Commencement Date") and shall end at the expiration of the term
of the Prime Lease.  Subtenant may cancel this Sublease at any time upon ninety
(90) days' notice to Sublandlord.

     3. RENT.  Subtenant shall pay to Sublandlord a monthly base rent (the
"Base Rent") equal to Subtenant's Share of rent, additional rent and other
obligations of Sublandlord payable to the Prime Landlord under the Prime Lease,
with respect to each month during the term of this Sublease, prorating such
obligations as may be required to the term of this Sublease, and adjusting such
amounts, from time-to-time as they may be adjusted between Prime Landlord and
Sublandlord under the Prime lease, all without offset, deduction or abatement,
except as otherwise expressly provided for herein. The Base Rent shall be
payable by Subtenant to Sublandlord in advance on or before the first 

<PAGE>   68

day of each calendar month during the term of this Sublease with appropriate
prorations for partial months.  The Base Rent, together with any and all other
amounts from time to time due under this Sublease from Subtenant to
Sublandlord, is hereinafter referred to collectively as the "Rent".

     If Subtenant fails to pay any installment of the Rent, within five (5)
business days following Subtenant's receipt of notice of Sublandlord's
non-receipt of such payment to help defray the additional cost to Sublandlord
for processing such late payments, Subtenant shall pay, upon receipt of a
written notice from Sublandlord, to Sublandlord, a late charge of four percent
(4%) of such amount plus interest from and after the due date of such rent
computed at a rate of eighteen percent (18%) per annum for the number of days
from the due date until the unpaid amount plus the late charge has been paid in
full.

     4. RELATIONSHIP TO PRIME LEASE.  This Sublease and Subtenant's rights
hereunder are expressly subject to and subordinate to the Prime Lease.
Subtenant shall not allow any action or omission of Subtenant, its employees,
agents, contractors or affiliates, to place Sublandlord in default or at
risk of being declared in default under the Prime Lease.  Sublandlord shall not
allow any action or omission of Sublandlord, its employees, agents, contractors
or affiliates to place either Sublandlord or Subtenant in default under the
Prime Lease.

     5. USE.  The Subleased Premises shall be used and occupied by Subtenant as
office space for the purpose of conducting computer data operations and for
related uses specifically permitted under the Prime Lease and for no other
purposes.  Subtenant will not occupy or use, nor permit to be occupied or used,
any portion of the Subleased Premises for any business or purpose which is
unlawful in part or in whole or deemed to be disreputable in any manner, or
extra hazardous on account of fire, nor permit anything to be done which is not
in compliance with the foregoing and which will increase the rate of fire
insurance on the Sublandlord's Premises or the Building, and if, by reasons of
acts of Subtenant inconsistent with the foregoing, there shall be any increase
in the rate of insurance on the Sublandlord's Premises or the Building or its
contents created by Subtenant's acts or conduct of business, Subtenant shall
pay the amount of such increase on demand.

     6. REQUIREMENTS OF LAW.  Subtenant at its sole expense shall comply with
all laws, orders and regulations of federal, state, county and municipal
authorities and with any direction of any public officer or officers, pursuant
to law.  Notwithstanding the foregoing, Subtenant shall not be required to
comply with any applicable law if such compliance would necessitate
improvements or changes being made to the Subleased Premises and such
improvements or changes are required to be made by all other tenants of the
Building, provided the cause for such improvements or changes is not related to
Subtenant's specific manner and use of the Subleased Premises, in such case,
Sublandlord shall make such improvements and changes to the Subleased Premises
or use Sublandlord's reasonable efforts to cause the Prime Landlord to do so,
provided that Subtenant shall have no obligation to pay rent at any time that
the Subleased Premises 

                                    - 2 -
<PAGE>   69

become substantially unusable for Subtenant's normal operations as a result of
such lack of compliance unless caused by Subtenant.

     7. SERVICES AND REPAIRS.  (a)  Under the Prime Lease, Prime Landlord has
agreed to furnish certain services to Sublandlord's Premises.  The times and
days on which such services shall be provided are set forth in such Prime Lease
and any attachment thereto.  Sublandlord shall use reasonable efforts not to
block the provisions of such services to Subtenant and to cause Prime Landlord
to provide those services which Prime Landlord provides to Sublandlord, but
failure to any extent to furnish or any stoppage of these defined services,
resulting from causes beyond control of Sublandlord or from any cause not the
fault of Sublandlord, shall not render Sublandlord liable in any respect for
damages to person, property or business, nor be construed as an eviction of
Subtenant or work an abatement of rent, nor relieve Subtenant from fulfillment
of any covenant or agreement hereof except payment of Rent if the Subleased
Premises become substantially unusable for Subtenant's normal business
operations as a result of such lack of service and as a result thereof
Sublandlord is relieved of its obligation to pay Rent under the Prime Lease.
Notwithstanding anything to the contrary herein, Subtenant shall be entitled to
a pro rata share of any rent abatement received by Sublandlord from Prime
Landlord in accordance with Paragraph 5(a) of the Prime Lease.  Subtenant shall
pay to Sublandlord within twenty (20) days such charges as Sublandlord may
reasonably prescribe based on a reasonable portion of Prime Landlord's charges
and Sublandlord's costs for any electric service requested by Subtenant and
supplied by Sublandlord or Prime Landlord, for heat or air conditioning service
for times other than as set forth in the Prime Lease or for computers and other
electrical equipment or other electric service deemed by Prime Landlord not to
be standard.

     (b) Under Paragraph 5.3.1 of the Prime Lease, Prime Landlord has agreed to
keep and maintain in good condition the Common Parts, Retained Parts,
Structure, Service Installations and roofs of the Building adequately renewed,
repaired, maintained, heated, cleaned and lighted.  Sublandlord shall use
reasonable efforts to cause Prime Landlord to provide above defined services to
Subtenant.  Provided Sublandlord has used reasonable efforts to cause Prime
Landlord to provide such services, Sublandlord shall have no responsibility for
the foregoing obligations of Prime Landlord and shall have no liability if such
services have not been provided, but Subtenant shall have no obligation to pay
Rent at any time that the Subleased Premises become substantially unusable for
Subtenant's normal business operations as a result of such lack of repair
provided that during such period Sublandlord is relieved of its obligation to
pay Rent under the Prime Lease.

     8. SUBTENANT'S REPAIRS AND ALTERATIONS.  (a)  Subtenant shall not in any
manner deface, damage or injure the Subleased Premises or the Building, and
shall pay the cost of repairing any damage or injury done to the Subleased
Premises or the Building or any part thereof by Subtenant or Subtenant's
agents, employees, contractors, customers or invited guests.  Subtenant shall
during the term of this Sublease take good care of the Subleased Premises and
keep them free from waste of any kind.  Subtenant shall keep the Subleased
Premises in good condition and make all necessary repairs, 

                                    - 3 -

<PAGE>   70

subject to Sublandlord's and Prime Landlord's obligations under Paragraph 7(b)
hereof.  At the expiration or earlier termination of this Sublease, Subtenant
shall deliver to Sublandlord the Subleased Premises with all improvements
thereon in good repair and condition, reasonable wear and tear, casualty and
condemnation excepted.  Subtenant shall not make or allow to be made any
alterations, additions or improvements in or to the Subleased Premises without
the prior written consent of Sublandlord which consent unless the consent of
the Prime Landlord is required, as hereinafter contemplated, shall not be
unreasonably withheld, conditioned or delayed if the aggregate cost of
restoration of all changes and alterations to be made by such tenant under this
Sublease shall not exceed $50,000.00 or if the aggregate cost of restoration
shall exceed such amount, such consent shall not be unreasonably withheld,
conditioned or delayed other than the agreement of Subtenant to pay such excess
amount of restoration cost may be imposed as a condition to such approval.  Any
such work shall be done at Subtenant's sole expense and without the creation of
mechanics' or materialmen's liens.  If such alterations, additions or
improvements would require Prime Landlord's written consent prior to their
performance by Sublandlord under the Prime Lease, then Sublandlord may at its
sole discretion withhold its consent to Subtenant's performance of such
alterations, additions or improvements, until receipt of Prime Landlord's
written consent, provided, however that Sublandlord shall use reasonable and
timely efforts to obtain Prime Landlord's written consent for such alterations,
additions or improvements.  Notwithstanding the foregoing, for structural
alterations, additions, or improvements, Sublandlord shall respond promptly to
Subtenant's request and may attach reasonable conditions to its consent
(including, but not limited to, removal of the alteration, addition or
improvement and restoration to its original state at termination or expiration
of the Sublease).  If a lien is placed against the Sublandlord's Premises or
the Building by reason of action by Subtenant, Subtenant shall post a proper
bond in or deposit with a title company or other escrow agent, an amount
sufficient to cover all amounts due under said lien within twenty (20) days. 
At the termination or expiration of this Sublease, unless Subtenant is to
remove structural alterations, additions or improvements erected by Subtenant
and restore the Subleased Premises to their original condition as a prior
condition to Sublandlord's consent above, such alterations, additions and
improvements shall be delivered to Sublandlord with the Subleased Premises. 
All furniture and moveable trade fixtures installed by Subtenant may be removed
by Subtenant at the termination of this Sublease if Subtenant so elects, and
shall be removed if Sublandlord or Prime Landlord so elects.  All such removals
and restoration shall be accomplished in a good workerlike manner so as not to
damage the Building.

     9. ASSIGNMENT AND SUBLETTING.  Subtenant may not assign this Sublease, nor
allow same to be assigned by operation of law or otherwise, nor sublet the
Subleased Premises or any part thereof without the prior written consent of
Sublandlord which consent shall not be unreasonably withheld, and without the
prior written consent of Prime Landlord.  Sublandlord will not unreasonably
withhold, delay or condition its consent to such subletting provided that
Subtenant has given Sublandlord not less than twenty (20) days' notice of such
subletting, during which time Sublandlord may elect, by notice to Subtenant to
cancel this Sublease with respect to the space proposed to be 


                                    - 4 -
<PAGE>   71

sublet, and in such event, the Rent shall thereafter be adjusted based on the
portion of the Subleased Premises then remaining.

     10. MAINTENANCE.  Subtenant, at its sole expense, shall maintain the
Subleased Premises in a clean and healthful condition, and subject to Paragraph
6 comply with all laws, ordinances, orders, rules, and regulations (state,
federal, municipal, and other agencies or bodies having any jurisdiction
thereof) with reference to use, condition, or occupancy of the Subleased
Premises.  Sublandlord shall maintain those portions of Sublandlord's Premises
outside the Subleased Premises in a clean and healthful condition and subject
to Paragraph 6 comply with all laws, ordinances, orders, rules and regulations
(state, federal, municipal, and other agencies or bodies have jurisdiction
thereof) with reference to use, condition, or occupancy of said portions of the
Sublandlord's Premises and the Building in accordance with the Prime Lease.

     11. INDEMNITY.  Neither party shall be liable for, and the other party
will indemnify and save harmless said party from, any and all fines, suits,
claims, costs, expenses, demands, and actions of any kind (including reasonable
attorney's fees) by reason of any negligence, misconduct, or any breach,
violation, or non-performance of any covenant hereof on the part of the other
party or its agents, employees, and/or invitees.  Neither party shall be liable
or responsible for any loss or damage to any property or person occasioned by
theft, fire, act of God, public enemy, injunction, riot, strike, insurrection,
war, court order, requisition or order of governmental body or authority or
other matter beyond such party's reasonable control, or for any damage or
inconvenience which may arise through repair or alteration of any part of the
Building, or failure to make repairs, or from any cause whatever except such
party's negligent act or omission, or willful misconduct or intentional breach
of this Sublease.  This Paragraph shall not preclude one party from seeking
reimbursement from the other for work or monies expended which is the
responsibility of the other party.  This Paragraph shall survive termination or
expiration of this Sublease.

     12. RULES AND REGULATIONS.  Subtenant and Subtenant's agents, employees,
and invitees, shall comply fully with all requirements of the Rules and
Regulations ("Rules and Regulations") of the Building, if any.  Subtenant
acknowledges that if pursuant to the Prime Lease, Prime Landlord may change
such Rules and Regulations or amend them from time to time, then upon receipt
thereof, Sublandlord shall deliver copies of all changes, and amendments
thereto, to Subtenant, and Subtenant shall comply therewith.

     13. INSPECTION.  Sublandlord and Prime Landlord, or their officers,
agents, and representatives, may enter into and upon any and all parts of the
Subleased Premises upon one (1) day's notice at all reasonable hours to inspect
same or clean or make repairs or alterations or additions as Sublandlord shall
reasonably deem necessary or as Prime Landlord may be entitled to under the
Prime Lease, except that in cases of emergency the right to enter shall not be
subject to any notice or time restrictions.

     14. CONDUCT OF BUSINESS.  Subtenant shall conduct its business, and
control its agents, employees, contractors, customers and invited guests in
such a manner as not to unreasonably interfere with, annoy or disturb other
tenants or Sublandlord or Prime Landlord in the management of the Building.
Sublandlord will conduct its business, and control its agents, employees,
contractors, customers and invited guests in such a manner as not to
unreasonably interfere with, annoy or disturb Subtenant's normal business
activities.

     15. CONDEMNATION.  If the Subleased Premises shall be taken or condemned
in whole or substantial part for public purposes, this Sublease shall
terminate.

     In the event of a partial condemnation, either Sublandlord or Subtenant
may elect, in its sole discretion, by notice to the other to terminate this
Sublease provided that if this Sublease shall not terminate, there shall be an
abatement of the Rent, on a square footage basis, to the extent and degree that
the Subleased Premises may no longer be utilized by Subtenant as a result of
the condemnation.

     If any part of the Subleased Premises shall be so taken and this Sublease
shall not be terminated under the provisions of this Paragraph, then
Sublandlord shall use reasonable efforts to cause Prime Landlord to perform
restoration, at Prime Landlord's own cost and expense, of the remaining portion
of the Subleased Premises to the extent necessary to render it reasonably
suitable for the purposes for which it was leased.  Sublandlord shall have no
responsibility to perform such restoration or liability in connection thereto
but, to the extent that Sublandlord is relieved of its obligation to pay rent
pursuant to the Prime Lease, Subtenant shall have no obligation to pay Rent at
any time the Subleased Premises become substantially unusable for Subtenant's
normal business operations as a result of such condemnation.

     16. FIRE & OTHER CASUALTY. If the Building should be totally or partially
destroyed by fire, tornado or other casualty, either Sublandlord or Subtenant
may, in its sole discretion, terminate this Sublease by notice to the other,
given within ninety (90) days of such casualty or, if Prime Landlord terminates
the Prime Lease pursuant thereto, this Sublease shall terminate.  If this
Sublease is not so terminated, Subtenant acknowledges that Prime Landlord is
required under the Prime Lease to rebuild and repair Sublandlord's Premises.
Sublandlord shall have no responsibility for such rebuilding and repair but, to
the extent that Sublandlord is relieved of its obligation to pay rent pursuant
to the Prime Lease, Subtenant shall have no obligation to pay Rent at any time
the Subleased Premises become substantially unusable for Subtenant's normal
business operations as a result of such casualty.

     Sublandlord and Subtenant shall each look first to any insurance in its
favor before making any claim against the other party for recovery for loss or
damage resulting from fire or other casualty and to the extent that such
insurance is in force and collectible and to the extent permitted by law.
Sublandlord and Subtenant each hereby releases and waives all right of recovery
against the other or any one claiming through or under each of them by way of
subrogation or otherwise.  The foregoing release and waiver shall be in force


                                    - 6 -
<PAGE>   73
only if both releasors' insurance policies contain a clause providing that such
a release or waiver shall not invalidate such insurance.  If such coverage is
available for a reasonable additional premium each party shall pay such
additional premium under its policy.  Subtenant acknowledges that Sublandlord
will not carry insurance on Subtenant's furniture and/or furnishings or any
fixtures or equipment improvements or appurtenances removable by Subtenant and
agrees that Sublandlord will not be obligated to repair any damage or replace
the same.  Throughout the term of this Sublease, Sublandlord shall carry
insurance on the leasehold improvements within the Subleased Premises to the
extent of the coverage as of the date of this Sublease.

     Subtenant shall carry and maintain (a) public liability insurance in the
amount of at least $1,000,000 and (b) property damage insurance in the amount
of at least $500,000.

     17. HOLDING OVER.  Should Subtenant, or any of its successors in interest,
hold over the Subleased Premises, or any part thereof, after the expiration of
the term of this Sublease or after the termination of this Sublease by
Sublandlord as a result of a default by Subtenant, unless otherwise agreed in
writing, such holding over shall constitute and be construed as a tenancy at
will only, at 150% of the Base Rent paid for the last month of the term of this
Sublease for that portion of the Subleased Premises held over.  If the holding
over continues for more than 180 days after notice given by Sublandlord to
Subtenant to vacate such space held over, the Base Rent shall be two (2) times
the above described Base Rent paid for that portion of the Subleased Premises
held over.  The inclusion of the preceding sentence shall not be construed as
Sublandlord's consent for Subtenant to hold over, nor require any notice from
Sublandlord to terminate Subtenant's tenancy, except as specifically provided
for herein, it being agreed that unless otherwise specifically agreed,
Sublandlord shall be entitled to immediate possession of the Subleased Premises
upon any termination of this Sublease.  Furthermore, in the event that such
holding over shall result in additional obligations or liability on the part of
Sublandlord to Prime Landlord, then Subtenant shall be responsible for such
additional obligations or liability and shall promptly satisfy such obligations
or liability on behalf of Sublandlord.

     18. TAXES ON SUBTENANT'S PROPERTY.  Subtenant shall be liable for all
taxes levied or assessed against personal property, furniture or fixtures of
Subtenant situated in the Subleased Premises.  If any such taxes for which
Subtenant is liable are levied or assessed against Sublandlord or Prime
Landlord or Sublandlord's or Prime Landlord's property and if Sublandlord or
Prime Landlord elects to pay the same or if the assessed value of Sublandlord's
or Prime Landlord's property is increased by inclusion of personal property,
furniture or fixtures placed by Subtenant in the Subleased Premises, and
Sublandlord or Prime Landlord elects to pay the taxes based an such increase,
Subtenant shall pay to Sublandlord or Prime Landlord, as applicable, within 
fifteen (15) days after written notice that part of such taxes for which 
Subtenant is primarily liable hereunder.

     19. EVENTS OF DEFAULT.  The occurrence of any one or more of the following
shall be deemed events of default by Subtenant under this Sublease.

                                    - 7 -
<PAGE>   74



     (a) Subtenant shall fail to pay any installment of the Base Rent or
additional rent hereby reserved or late charge and such failure shall continue
for ten (10) days after notice by Sublandlord of its non-receipt of such Rent.

     (b) Subtenant shall fail to comply with any material term, provision, or
covenant of this Sublease, other than the payment of the Rent, and shall not
have cured such failure within twenty (20) days or such further period if it is
of such a nature that it cannot be reasonably cured within such twenty (20) day
period after written notice thereof to Subtenant.

     (c) Subtenant shall make a statutory and/or common law assignment for the
benefit of creditors.

     (d) Subtenant shall file a petition under any section or chapter of the
Bankruptcy Code, as amended, or under any similar liquidation, reorganization,
insolvency, dissolution or arrangement law or statute of the United States or
any State thereof; or Subtenant shall be adjudged bankrupt or insolvent in
proceedings filed against Subtenant thereunder and such adjudication shall not
be vacated, set aside or dismissed within sixty (60) days or stayed within five
(5) working days.

     (e) A receiver, Trustee, custodian or similar official shall be appointed
for all or substantially all of the assets of Subtenant and such receivership
shall not be terminated or stayed within the time permitted by law.

     (f) Subtenant shall have commenced a judicial and/or non-judicial
corporate dissolution proceeding.

     20. REMEDIES.  On the occurrence of any event of default specified in
Paragraph 19 hereof, which is not cured within five (5) business days of
Subtenant's receipt of subsequent notice from Sublandlord that the respective
cure periods in Paragraph 19 have expired, without Subtenant's curing, or if
applicable, commencing diligent efforts to cure the same, Sublandlord shall
have the option to pursue any one or more of the following remedies without any
notice or demand whatsoever:

     (a) Terminate this Sublease in which event Subtenant shall immediately
surrender the Subleased Premises to Sublandlord, and if Subtenant fails to do
so, Sublandlord may, without prejudice to any other remedy which it may have
for possession or arrearages in rent, enter upon and take possession and expel
or remove Subtenant and any other person who may be occupying the Subleased
Premises or any part thereof, by force if necessary, without being liable for
prosecution or any claim of damages thereof; and Subtenant agrees to pay to
Sublandlord on demand the amount of all loss and damage which Sublandlord may
suffer by reason of such termination, whether through inability to relet the
Subleased Premises on satisfactory terms or otherwise, said loss and damage to
include all damages to which Sublandlord is entitled at law arising from
Subtenant's breach and the termination of this Sublease.


                                    - 8 -
<PAGE>   75



     (b) Enter upon the Subleased Premises by reasonable force if necessary
without being liable for prosecution or any claim for damages therefor, and do
whatever Subtenant is obligated to do under the terms of this Sublease; and
Subtenant agrees to reimburse Sublandlord on demand for any reasonable expenses
which Sublandlord may incur in thus effecting compliance with Subtenant's
obligations under this Sublease, and Subtenant further agrees that Sublandlord
shall not be liable for any damages resulting to the Subtenant from such
action.

     Pursuit of any of the foregoing remedies shall not preclude pursuit of any
of the other remedies herein provided or any other remedies provided by law,
nor shall pursuit of any remedy herein provided constitute a forfeiture or
waiver of any rent due to Sublandlord hereunder or of any damages occurring to
Sublandlord by reason of the violation of any of the terms, provisions and
covenants herein contained.  Sublandlord's acceptance of rent following an
event of default hereunder shall not be construed as Sublandlord's waiver of
such event of default.  No waiver by Sublandlord of any violation or breach of
any of the terms, provisions and covenants herein contained shall be deemed or
construed to constitute a waiver of any other violation or breach of any of the
terms, provisions, and covenants herein contained.  Forbearance by Sublandlord
to enforce one or more of the remedies herein provided upon an event of default
shall not be deemed or construed to constitute a waiver of such default.  None
of the foregoing shall diminish or eliminate Sublandlord's obligation to
mitigate damages to the extent such obligation exists under the laws of the
state in which the Subleased Premises are located.

     21. SURRENDER OF PREMISES.  No act or thing done by Sublandlord or its
agents during the term hereby granted shall be deemed an acceptance of a
surrender of the Subleased Premises, and no agreement to accept a surrender of
the Subleased Premises shall be valid unless the same be made in writing and
subscribed by Sublandlord.

     22. ATTORNEY'S FEES.  If it should be necessary or proper for either
Sublandlord or Subtenant to bring any action under this Sublease to recover any
amount payable hereunder, or for the enforcement of any of Sublandlord's or
Subtenant's rights hereunder, the party prevailing completely on all issues
shall have the right to recover in any such case a reasonable attorney's fee.

     23. RECEIPTS FROM ASSIGNEE OR SUBTENANT.  The receipt by Sublandlord or
Prime Landlord of rent from any assignee, subtenant or occupant of the
Subleased Premises shall not be deemed a waiver of the covenant in this
Sublease contained against assignment and subletting or an acceptance of the
assignee, subtenant or occupant as tenant or a release of Subtenant from the
further observance or performance by Subtenant of the covenants in this
Sublease contained, on the part of Subtenant to be observed and performed.  No
provision of this Sublease shall be deemed to have been waived by the parties
unless such waiver be in writing signed by said party.

     24. QUIET ENJOYMENT; SUBLANDLORD'S REPRESENTATIONS.  Subtenant, upon the
payment of the rentals and performance of the covenants on Subtenant's part to
be performed hereunder, shall and may peaceably and quietly have, 

                                    - 9 -
<PAGE>   76


hold and enjoy the Subleased Premises during the term hereof and any 
extensions thereof, free from interference or disturbance from Sublandlord, 
but subject to the terms and conditions of this Sublease and the Prime Lease.  
Notwithstanding anything to the contrary, Sublandlord shall not be liable for 
any interference or disturbance from other tenants or third persons, nor shall 
Subtenant be released from any of the obligations of this Sublease because of 
such interference or disturbance, unless such results from a third party 
claiming through Sublandlord or Sublandlord fails to enforce diligently its 
rights to cause such interference or disturbance to cease; provided that, to 
the extent that Sublandlord is relieved of its obligation to pay rent pursuant 
to the Prime Lease, Subtenant shall not be obligated to pay Rent at any time the
Subleased Premises become substantially unusable for Subtenant's normal
business operations as a result of any such disturbance of Subtenant's
possession of the Subleased Premises.

     If Sublandlord shall fail to comply with any material term, provision, or
covenant of this Sublease, Subtenant may give notice to Sublandlord to correct
such default.  Sublandlord shall have the right to correct or remedy such
default before Subtenant may take any action under this Sublease by reason of
such default.  If such default shall continue for forty-five (45) days after
such written notice, or such further period as may be reasonably required to
cure such default if it is of such a nature that it cannot reasonably be cured
within such forty-five (45) day period, the Rent shall be abated on a square
footage basis during the period the Subleased Premises or a part thereof is
unfit for occupancy.

     Sublandlord represents and warrants to Subtenant that:

     (a) Sublandlord has heretofore provided Subtenant with a copy of the Prime
Lease and all amendments and modifications thereof;

     (b) there has been no assignment of Sublandlord's interest therein or
sublease of the Subleased Premises, other than pursuant to this Sublease;

     (c) Sublandlord is fully authorized to enter into this Sublease and no
consent from any third party (except Prime Landlord) is required to authorize
Sublandlord to enter into this Sublease; and

     (d) to the best knowledge of Michael Manchisi, Vice President - Global
Operations Administration of Sublandlord, (i) there is no current major dispute
or litigation between Sublandlord and Landlord with respect to the Prime Lease,

the Prime Lease, and (iii) Sublandlord has received no any written notice of
any material problem regarding the compliance of the Subleased Premises with
local and federal codes, statutes and laws, including without limitation the
Americans with Disabilities Act and environmental laws.

     Sublandlord shall hold Subtenant harmless from and against any costs,
damage or liability to Subtenant arising out of Sublandlord's default or
failure to comply with the 

                                   - 10 -

Prime Lease or any provision of law compliance with which is required by the

strikes, riots, acts of God, shortages of labor or materials, war, governmental
laws, regulations, or restrictions, or any other causes of any kind whatsoever
which are beyond the control of said party.  This Paragraph shall apply only to

     34. GOVERNING LAW.  This Sublease shall be construed in accordance with
the law of the state in which the Subleased Premises are situate.

     35. PARKING.  To the extent Sublandlord has rights to parking under the
Prime Lease or by other agreement with the Prime Landlord, Subtenant shall,
without additional cost, be entitled to a portion of such parking privileges
based on its share of the Sublandlord's Premises.

     36. LICENSED AREAS.  Also shown on Exhibit A(1) are certain portions of
the Building (the "Licensed Areas") of which Sublandlord is tenant under the
Prime Lease, which Sublandlord hereby licenses to Subtenant to use, on a
non-exclusive basis, to provide ingress and egress to the Subleased Premises,
access to fire exits and emergency facilities and for bathrooms and access
thereto.  Subtenant's use of the Licensed Areas shall be limited to those uses
ancillary to its occupancy of the Subleased Premises and for no other purpose
and shall be exercised in a manner which shall (a) not unreasonably interfere
with Sublandlord's use of such areas, (b) be in compliance with all laws,
orders and regulations of federal, state, county and municipal authorities and

the same may be shortened or terminated pursuant hereto.  Subtenant's
obligations to insure and indemnify Sublandlord with respect to the Subleased
Premises shall also extend to the Licensed Areas.  A violation by Subtenant of

Share") of Sublandlord's Premises or Sublandlord's costs, such calculation

as the denominator the area of the Sublandlord's Premises diminished by the
area of the Licensed Areas.

     IN WITNESS WHEREOF, the parties have executed this Sublease on the dates
set forth below and this Sublease shall be effective as of the latter of such
dates.

     NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants contained herein, the Company and NDCI agree as follows:

                            TERMS AND CONDITIONS

      1. NEWCO SERVICES:  According to the terms of this Agreement, the Company
      will furnish NDCI and its Affiliates with the data processing services
      described in Exhibit A, Service Description, attached hereto and
      incorporated herein by reference.  Additional requested Services, if
      available, will be furnished to NDCI under the general terms and
      conditions of this Agreement and in accordance with pricing as set forth
      in Paragraph 2, below.  Any such additional Services will be as described
      in additional Exhibits A to this Agreement, each of which shall be signed
      by both parties hereto.  Any Exhibit A may contain terms different than
      those contained in this Agreement, and in such event the terms of each
      such Exhibit A shall control with respect to the Services described in
      such Exhibit A.

      2. CHARGES:  Charges for the Services shall be equal to the Company's
      actual cost (including a reasonable allocation of the administrative
      overhead of the Company relating to the provision of such services) for
      providing the Services.  In addition, NDCI will be charged an amount
      equal to any taxes, however designated, levied or based on any of the
      above referred to charges or Services, including State and local taxes
      paid or payable by the Company, excluding any federal, State or local
      taxes based on the Company's net income.



<PAGE>   82



      The Company will bill NDCI monthly for all charges incurred by NDCI,
      including any authorized charges incurred by the Company on NDCI's behalf
      for NDCI's use of the Services as provided for in this Agreement.  NDCI
      agrees to pay the Company upon receipt of each monthly invoice, and
      agrees further to pay a one percent (1%) per month service charge on all
      invoices that are not paid within thirty (30) days following such
      receipt.  All payments shall be made in United States Dollars.  In the
      event that any invoice is not timely paid as provided herein, the Company
      may, in addition to any other right or remedy which it may have under
      this Agreement or at law, terminate this Agreement and NDCI's use of the 
      Services if NDCI does not effect payment in full within ten (10) days of 
      the Company's written demand therefor.  NDCI agrees to reimburse the 
      Company for all costs and expenses, including reasonable attorney's fees,
      incurred by the Company in enforcing collection of any moneys due it 
      under this Agreement.

      3.     TERM AND TERMINATION:

      a.       This Agreement shall remain in full force and effect for an
           initial term of five (5) years, beginning upon the effective date
           set forth above, and shall be automatically extended for successive
           one (1) year periods on the same terms and conditions expressed
           herein, or as may be amended, unless either party gives the other
           party written notice of termination at least thirty (30) days prior
           to the expiration of the initial term or any extensions or renewals
           thereof. Termination of this Agreement shall not terminate NDCI's
           obligation to pay the Company for all services performed under the
           Agreement prior to discontinuance of performance by the Company due
           to termination.

      b.       Except as provided in Paragraph 2 above, in the event that
           either party hereto fails in the performance of its obligations
           hereunder or breaches the terms or conditions hereof, the other
           party may, at its option, give written notice to the party which has
           failed to perform or has breached this Agreement of its intention to
           terminate this Agreement unless such breach or failure in
           performance is remedied within thirty (30) days of such notice.
           Failure to remedy such a breach shall make this Agreement
           terminable, at the option of the aggrieved party, at the end of such
           thirty (30) day period unless notification is withdrawn.

      4.     CHANGE OF CHARGES:  The Company shall have the right to increase 
      the fees and charges paid by NDCI to offset any increase in rates 
      charged by any third party service providers utilized by the Company in 
      the provision of Services hereunder.  Any such increase shall become
      effective on the same day as the increase in rates charged by the
      communications common carrier becomes effective.


                                    - 2 -
<PAGE>   83



      The Company shall also have the right to increase such fees and charges
      to offset any increase to the Company in the costs of providing the
      Services hereunder.  Any such increase shall become effective as of the
      date on which the Company notifies NDCI of such increase.

      5.     USE OF THE SERVICES:  NDCI agrees to utilize the Services in
      accordance with this Agreement, its exhibits, and the Company's
      reasonable Service instructions and specifications and to provide the
      Company with the necessary data in the proper format to enable the
      Company to properly furnish the Services.

      6.     LIMITATION OF LIABILITY:

      a.        The Company shall not be liable for failure to provide the
           Services if such failure is due to any cause or condition beyond its
           reasonable control.  Such causes or conditions shall include but 
           shall not be limited to, acts of God or of the public enemy, acts 
           of the Government in either its sovereign or contractual capacity, 
           fires, floods, epidemics, quarantine restrictions, strikes, 
           shortages of labor or materials, freight embargoes, unusually 
           severe weather, electrical power failures, or other similar causes 
           beyond the Company's control and the Company shall have no 
           liability for losses, expenses or damages, ordinary, special or 
           consequential resulting directly or indirectly from such causes. If 
           the Company's failure to provide the Services is caused by the 
           default of a subcontractor, and if such default arises out of 
           causes beyond the control of both the Company and the subcontractor, 
           the Company shall not be liable unless the supplies or Services to 
           be furnished by the subcontractor were obtainable from other 
           sources in sufficient time to permit the Company to fulfill its 
           obligations hereunder.

      b.        The Company agrees to use its best efforts at all times to
           provide prompt and efficient services; however, the Company makes no
           warranties or representations regarding the Services except as
           specifically stated in this Paragraph 6.b.  The Company shall use
           due care in processing all work submitted to it by NDCI and agrees
           that it will, at its expense, correct any errors which are due
           solely to malfunction of the Company's computers, operating systems
           or programs, or errors by the Company's employees or agents.
           Correction shall be limited to rerunning of the job or jobs and/or
           recreating of data or program files.  The Company shall not be
           responsible in any manner for errors or failures of or errors in
           proprietary systems and programs other than those of the Company,
           nor shall the Company be liable for errors or failures of NDCI's
           software or operational systems, including any software licensed to
           the Company by NDCI.  THIS WARRANTY IS EXCLUSIVE AND IS IN LIEU OF
           ALL OTHER WARRANTIES, AND SUBSCRIBER HEREBY WAIVES ALL OTHER


                                    - 3 -
<PAGE>   84



           WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY INCLUDING, BUT NOT
           LIMITED TO, ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR USE FOR A
           PARTICULAR PURPOSE.  Should there be any failure in performance or
           errors or omissions with respect to the information being
           transmitted, the Company's liability shall be limited to using its
           best efforts to correct such failure in performance or errors or
           omissions.  In no event, except as specifically set forth herein,
           shall the Company be liable to NDCI or any third parties (including
           NDCI's customers) for any claim, loss or damage, ordinary, special
           or consequential, or otherwise, even if the Company has been advised
           of the possibility of such damage.

           Due to the nature of the services being performed by the Company,
           it is agreed that in no event will the Company be liable for any
           claim, loss, liability, correction, cost, damage or expense caused
           by the Company's performance or failure to perform hereunder which
           is not reported by NDCI within one hundred twenty (120) days of
           such failure to perform.

      c.        NDCI shall indemnify and hold harmless the Company from and
           against any and all loss, damage, or expense or claims of damage or
           liability, ("Claims") asserted against the Company by third parties
           arising out of the performance of Services under this Agreement or
           from information provided to the Company by NDCI or NDCI's
           customers, or arising out of the use of such information when
           furnished by the Company to NDCI's customers or to other third
           persons at NDCI's request, or to officers, employees and agents of
           NDCI; provided, however, that such indemnity obligation does not
           apply in cases where such Claims arise primarily from the gross
           negligence or intentional misconduct of the Company.

      d.        Liability of the Company in any and all categories and for
           any and all causes arising out of this Agreement shall, in the
           aggregate, not exceed six (6) month's average billing to NDCI taken
           over the twelve (12) months preceding the month in which the damage
           or injury is alleged to have occurred, but if this Agreement has not
           been in effect for twelve (12) months preceding such date, then over
           such fewer number of preceding months that this Agreement has been
           in effect.

      7.      PROPRIETARY INFORMATION:

      a.        All proprietary information disclosed by either party to the
           other in connection with this Agreement shall be identified as such
           in writing if not already identified as such herein, and shall be
           protected by the recipient party from disclosure to others.  All
           software, data, or other intellectual property provided by the
           Company under this Agreement is hereby 


                                    - 4 -
<PAGE>   85


           identified as proprietary to the Company and may not be copied
           or used in any way other than as specifically authorized in this
           Agreement.  Any software or data furnished by NDCI to the Company in
           connection with this Agreement is identified as proprietary to NDCI,
           but may be used as required by the terms of this Agreement and
           retained by the Company until performance under this Agreement is
           completed or until this Agreement is terminated, whichever occurs
           first, at which time such information and all copies thereof shall
           be returned to NDCI upon request.

      b.        The Company and NDCI acknowledge that all proprietary
           information disclosed by either party to the other party for the
           purpose of work, or which comes to the attention of one of the
           parties, its employees, officers, and agents during the course of
           such work, constitutes a valuable asset.  Therefore, the Company and
           NDCI agree to hold such information in confidence and shall not,
           except in the performance of the duties under this Agreement or with
           the express prior written consent of the other party, disclose or
           permit access to any such information to any person, firm or
           corporation other than persons, firms or corporations authorized
           by that party, and the Company and NDCI shall cause their
           officers, employees, agents, and representatives to take such
           action as shall be necessary or advisable to preserve and protect
           the confidentiality of such information.

      c.        The Company's and NDCI's obligations and agreements under
           this Paragraph shall not apply to any information supplied that:

           (1)       was known to either party prior to the
                  disclosure by the other, or

           (2)       is or becomes generally available to the public
                  other than by breach of this Agreement, or

           (3)       otherwise becomes lawfully available on a
                  nonconfidential basis from a third party who is not under an
                  obligation of confidence to either party.

      8.      MISCELLANEOUS:

      a.        This Agreement shall be construed in all respects under the
           laws of the State of Georgia without reference to conflicts of laws
           provisions.

      b.        This Agreement contains the full understanding of the parties
           with respect to the subject matter hereof, and no waiver, alteration
           or modification of any of the provisions hereof shall be binding
           unless in writing and signed by officers of both parties.  In the
           event NDCI issues a purchase order or memorandum or other instrument
           covering the Services 

                                    - 5 -
<PAGE>   86


           herein offered and provided, it is hereby specifically agreed
           and understood that such purchase order or memorandum or instrument
           is for NDCI's internal purposes only and any and all terms and
           conditions contained therein, whether printed or written, shall be
           of no force or effect.

      c.        If any part of this Agreement shall be held to be void or
           unenforceable, such part will be treated as severable, leaving valid
           the remainder of this Agreement notwithstanding the part or parts
           found to be void or unenforceable.

      d.        Except as otherwise provided in this Agreement, notices
           required to be given pursuant to this Agreement shall be effective
           when received, and shall be sufficient if given in writing, hand
           delivered, sent by telegraph or First Class United States Mail,
           postage prepaid and addressed to the appropriate party at the
           address set forth on the signature page hereof.

           The parties hereto may change the name and address of the
           person to whom all notices or other documents required under this
           Agreement must be sent at any time by giving written notice to the
           other party.

      e.        Neither party to this Agreement may assign its rights or
           obligations under this Agreement without the express written consent
           of the other party, except that the obligations of the Company under
           this Agreement may be provided or fulfilled by any parent,
           subsidiary, affiliate, successor corporation or subcontractor of the
           Company so long as the Company assumes full responsibility for such
           obligations.
