     which occur both (A) under the Merchant Agreements, Agent Bank Agreements,

     assigned to Purchaser pursuant to this Agreement; and (B) on or after the
     Closing Date;

          (iii)  charge-backs in respect of any Credit Card or Debit Card
     transaction processed by Purchaser pursuant to a Merchant Agreement, Agent
     Bank Agreement, ISO Agreement or Related Agreements included within the
     Transferred Assets assigned to Purchaser pursuant to this Agreement if such
     Credit Card or Debit Card transaction is received by electronic
     transmission or otherwise under and in compliance with the rules and
     regulations of Credit Card Associations, EFT Networks or EBT Networks (as
     applicable) on and after the Closing Date, and other Credit Losses on and
     after the Closing Date, but only to the extent that such charge-back or
     other Credit Loss relates to or arises out of an original sales transaction
     occurring on or after the Closing Date;

          (iv)   all other liabilities and obligations of Purchaser arising on
     or after the Closing Date as successor to Seller under each of the
     Transferred Assets; and

          (v)    any other claims, liabilities or litigation (including, without
     limitation, liabilities for Taxes) in respect of the Merchant Agreements,
     Agent Bank Agreements, ISO Agreements and Related Agreements included
     within the Transferred Assets assigned to Purchaser pursuant to this
     Agreement or any other Transferred Asset or the Merchant Acquiring Business
     conducted in connection with the foregoing, provided that any such claims,
     liabilities or litigation relates to or arises out of events, transactions
     or actions or omissions of Purchaser on or after the Closing Date.

          (c)    The Assumed Liabilities assumed by Purchaser hereunder shall be
limited to the liabilities and obligations specified in Section 1.2(b)(i)
through (v) above and, without limitation of the foregoing, shall not in any
event include any other liabilities or obligations of Seller, which excluded
liabilities and obligations shall include the following liabilities or
obligations (the "Excluded Liabilities"):

          (i)    penalties or fees that may be incurred by Seller in connection
     with the termination of Seller's agreement(s) with any third party service

     respect of any Merchant Agreement that result from transactions, or events,
     or acts or omissions of Seller, or a Merchant, Agent Bank or Independent
     Sales Organization which occurred prior to the Closing Date (except for the
     fees to be paid by Paymentech as set forth in Section 3.6 which shall not
     be Excluded Liabilities);

          (ii)   all liabilities of Seller relating to or incurred in connection
     with the Excluded Assets;

     retention bonus payments, or any liability or indebtedness with respect to
     any wages, back pay, incentive bonuses, commissions, stock-based
     compensation, other payroll-related items or taxes or liabilities in

          (v)    except as set forth in Section 3.4(c), all liabilities of
     Seller with respect to any retained Employees;

          (vi)   all liabilities of Seller or affiliates of Seller relating to
     any Agreement Requiring Consent until such time as the necessary
     affirmative consents are obtained, whereupon said liabilities shall
     automatically and without further action become Assumed Liabilities;

          (vii)  all liabilities of Seller arising in connection with its
     operations unrelated to the Merchant Acquiring Business;

          (viii) any other assessments, fees, penalties, charge-backs, claims,
     liabilities or litigation in respect of any Excluded Assets; and

          (ix)   all assessments, association fees, interchange fees and similar
     fees, penalties and liabilities that relate to the operation of the
     Transferred Assets and the Merchant Acquiring Business prior to the Closing
     Date (including without limitation any claims, liabilities or litigation
     that relate to the operation of the Transferred Assets and the Merchant
     Acquiring Business and that accrue from any transaction, event, action or
     omission of Seller prior to the Closing Date).

          (d)    It is understood and agreed that Purchaser shall not assume or
become liable for the payment of any debts, liabilities, losses, Credit Losses,
charge-backs, accounts payable, bank indebtedness, mortgages, or other
obligations of Seller, any Merchant, any Agent Bank, any Independent Sales
Organizations or Related Party, whether the same are known or unknown, now
existing or hereafter arising, of whatever nature or character, whether absolute
or contingent, liquidated or disputed, except for Assumed Liabilities.

          1.3.   Transition Cooperation.

          (a)    From and after the date hereof and until the Conversion Date,
Seller and Purchaser shall use all commercially reasonable efforts in assisting
the other party with the "conversion" of the Merchant Acquiring Business herein
contemplated and the transition of the Merchant Acquiring Business from Seller
to Purchaser.  Regarding any Merchant Agreements included in the Transferred
Assets, Seller also shall use all commercially reasonable efforts to encourage
the Merchants that are parties thereto to continue doing business with Purchaser
under any such Merchant Agreements.

          (b)    Without limiting the generality of the foregoing, promptly
following the execution of this Agreement, Seller shall cause to be delivered to
each such Merchant a notice, in form and substance mutually acceptable to Seller
and Purchaser, of the assignment by Seller to Purchaser, effective as of the
Closing Date, of all rights in and to such Merchant Agreements.  If Seller and
Purchaser so agree, such notice may inform each such Merchant of Purchaser's
intention to convert that Merchant from the Mellon Payment Processing System to
Purchaser's network, as well as to a clearing bank and merchant accounting
system designated by Purchaser.

          (c)    From and after the date hereof and until the Conversion Date,
Seller and Purchaser shall each from time to time upon the reasonable request of
the other party cooperate with the other party to provide each other and the
Merchants, Agent Banks, Independent Sales Organizations and Related Parties that
are parties to the Merchant Agreements, Agent Bank Agreements, ISO Agreements
and Related Agreements included within the Transferred Assets with information
regarding the Year 2000 compliance status of Seller and Purchaser.  The
information that may be requested may consist of brief summaries of the testing
and analysis which Seller or Purchaser has performed, any exceptions to Year
2000 compliance (including a brief summary of plans for dealing with the
exceptions), and any other information required to be
<PAGE>
 
provided to such Merchants, Agent Banks, Independent Sales Organizations or
Related Parties by applicable law. Both Seller and Purchaser understand and
agree that nothing in this Section 1.3(c) is intended, or shall be construed, as
a representation or warranty regarding the Year 2000 compliance status of
Seller, Purchaser or any other Person, and that neither Seller nor Purchaser
shall make any representation or warranty, or provide any information, regarding
the other party's Year 2000 compliance status without the express prior written
consent of the other party.

          1.4.   Procedures for Transferred Assets not Transferable.

          (a)    Seller shall use all commercially reasonable efforts to obtain
Full Transfer of the Merchant Agreements, Agent Bank Agreements, ISO Agreements
and Related Agreements after the execution of this Agreement until February 15,
1999 and Purchaser shall use all commercially reasonable efforts to assist
Seller in that endeavor.

          (b)    Anything in this Agreement to the contrary notwithstanding,
this Agreement shall not constitute an agreement to assign or delegate any
Merchant Agreement, Agent Bank Agreement, ISO Agreement or Related Agreements
included within the Transferred Assets, or any claim, right, benefit, duty,
obligation or liability arising thereunder or resulting therefrom, if an
attempted assignment or delegation thereof, without the affirmative consent of a
third party, would be ineffective or would constitute a breach or other
contravention of such Merchant Agreement, Agent Bank Agreement, ISO Agreement or
Related Agreement or give rise to any right of termination thereof.

          (c)    Purchaser acknowledges and agrees that the failure of Seller to
obtain or  consummate Full Transfer with respect to any Merchant Agreement,
Agent Bank Agreement, ISO Agreement or Related Agreement included within the
Transferred Assets shall not be deemed a breach by Seller of any provision of
this Agreement and, except as specifically provided in Section 1.4(d) below,
shall not give Purchaser any right to terminate, rescind, modify or seek
indemnification, adjustment of the Purchase Price or any other monetary
consideration, with respect to this Agreement and the transactions contemplated
hereby, and Purchaser and Seller acknowledge and agree that Purchaser's remedy
with respect to Seller's failure to obtain or consummate Full Transfer with
respect to such Merchant Agreement, Agent Bank Agreement, ISO Agreement or
Related Agreement is set forth in Section 1.4(d) below.  Purchaser and Seller
agree to use commercially reasonable efforts, and to cooperate with each other,
in obtaining or executing and delivering promptly such other affirmative
consents and Transfer Documents, and in taking such other actions, as are
necessary or desirable in order to obtain or consummate Full Transfer with
respect to any Merchant Agreement, Agent Bank Agreement, ISO Agreement or
Related Agreements included within the Transferred Assets; provided, however,
                                                           --------  ------- 
that no such actions shall require Purchaser or Seller to pay money (other than
routine filing fees) to third parties in order to induce such parties to furnish
any consent or approval needed to obtain or consummate Full Transfer unless the
paying party consents in writing to such payment.  If Full Transfer has not
occurred with respect to any Merchant Agreement, Agent Bank Agreement, ISO
Agreement or Related Agreement as of the Closing Date, Seller shall perform all
obligations and duties under such Merchant Agreement, Agent Bank Agreement, ISO
Agreement or Related Agreement for the benefit of the Purchaser pursuant to the
Interim Transaction Processing Agreement until the Conversion Date.  Upon
obtaining Full Transfer of any such Merchant Agreement, Agent Bank Agreement,
ISO Agreement or Related Agreement prior to the Conversion Date, such Merchant
Agreement, Agent Bank Agreement, ISO Agreement or Related Agreement shall be
deemed assigned and transferred to Purchaser hereunder as of the Closing Date,
Purchaser shall be entitled to retain all net revenue resulting from original
sales transactions occurring on or after the Closing Date and Seller shall be
entitled to make a claim against the Holdback Amount in an amount as set forth
on Schedule 1.4(d) with respect to such Merchant Agreement, Agent Bank
Agreement, ISO Agreement or Related Agreement, plus interest at the rate of five
percent (5%) per annum on such amount from the Closing Date to the date prior to
the day such funds are paid by Purchaser to Seller.
<PAGE>
 
          (d)    To the extent that Seller has not obtained Full Transfer of any
Merchant Agreement, Agent Bank Agreement, ISO Agreement or Related Agreement
included in the Transferred Assets and identified on Schedule 1.4(d) on or
before February 15, 1999, Purchaser shall elect on or before February 26, 1999
whether to:

          (i)    accept the assignment absent a Full Transfer, in which case,
notwithstanding the failure to obtain Full Transfer, Purchaser shall to the
extent practicable assume the obligations, duties and liabilities, and Purchaser
shall be entitled to the practical benefit, under any such Merchant Agreement,
Agent Bank Agreement, ISO Agreement or Related Agreement, which shall be deemed
assigned and transferred to Purchaser as of the Closing Date, Purchaser shall be
entitled to all net revenue resulting from original sales transactions occurring
on or after the Closing Date and Purchaser shall pay to Seller that portion of
the Holdback Amount identified with respect to such Merchant Agreement, Agent
Bank Agreement, ISO Agreement or Related Agreement in an amount as set forth on
Schedule 1.4(d), plus interest at the rate of five percent (5%) per annum on
such amount from the Closing Date to the date immediately prior to the date such
funds are paid by Purchaser to Seller and Seller shall have no liability to
Purchaser solely resulting from the failure to obtain Full Transfer of such
Merchant Agreement, Agent Bank Agreement, ISO Agreement or Related Agreement; or

          (ii)   reject the assignment, in which case, notwithstanding any other
provisions of this Agreement, (A) Seller shall be deemed to have retained all
claims, rights, benefits (including the revenues net of interchange fees, dues
and assessments, Subsidies and third-party processing fees attributable to such
Merchant Agreement, Agent Bank Agreement, ISO Agreement or Related Agreement, if
any), obligations, duties and liabilities under such Merchant Agreement, Agent
Bank Agreement, ISO Agreement or Related Agreement as of the Closing Date, (B)
Purchaser shall be entitled to (I) retain that portion of the Holdback Amount
identified with respect to such Merchant Agreement, Agent Bank Agreement, ISO
Agreement or Related Agreement in an amount  as set forth on Schedule 1.4(d)
with respect to each rejected Merchant Agreement, Agent Bank Agreement, ISO
Agreement or Related Agreement and (II) reimbursement of all Transaction Fees
(as defined in the Interim Transaction Processing Agreement) incurred by
Purchaser from the Closing Date to the Conversion Date, for each such Merchant
Agreement, Agent Bank Agreement, ISO Agreement or Related Agreement rejected by
Purchaser under this Section 1.4(d)(ii), (C) neither this Agreement nor the
Transfer Documents shall constitute a sale, assignment, assumption, transfer,
conveyance or delivery or an attempted sale, assignment, assumption, transfer,
conveyance or delivery of any such Merchant Agreement, Agent Bank Agreement, ISO
Agreement or Related Agreement, and (D) Purchaser shall remit the revenues net
of interchange fees, dues and assessments, Subsidies and third-party processing
fees attributable to such Merchant Agreement, Agent Bank Agreement, ISO
Agreement or Related Agreement, as applicable, in immediately available funds
within thirty (30) days of the rejection of assignment.

If Purchaser does not expressly accept or reject the assignment pursuant to this
Section 1.4(d), Purchaser shall be deemed to have rejected the assignment.

          1.5.   Books and Records.    (a)  As soon after the Closing Date as is
practicable, and in no event later than ten (10) days following the Conversion
Date, Seller shall cause to be delivered to Purchaser the originals or, in the
event Seller is entitled to keep the originals pursuant to this Section 1.5 or
if Seller does not have in its possession such originals, copies, of all books,
records and documents, or portions thereof, of Seller relating to the
Transferred Assets; provided, however, that in no event shall such books,
records and documents include corporate books or records involving operations
other than the Merchant Acquiring Business, and further provided that Seller may
retain the originals or copies of such documents other than the Merchant
Agreements, Agent Bank Agreements, ISO Agreements and Related Agreements
included within the Transferred Assets as may be reasonably necessary for
Seller's business.  In each case, however, the books and records relating to the
Transferred Assets for the period prior
<PAGE>
 
to the Closing Date, wherever located, that are held by a party hereto or under
the control of a party hereto (the "Inspected Party") shall be open for
inspection by the other party, and such other party's authorized agents and
representatives and regulators may, at such other party's own expense, make such
copies of any excerpts from such books, records and documents as it shall
reasonably deem necessary; provided, however, that any such inspection: (i)
shall be conducted during normal business hours from time to time reasonably
established by the Inspected Party; (ii) shall, if the Inspected Party so
requests, be conducted in the presence of an officer or designated
representative of the Inspected Party; and (iii) shall be conducted in
accordance with reasonable security programs and procedures from time to time
established by the Inspected Party, including but not limited to such
confidentiality agreements as the Inspected Party may reasonably request.

          (b)    All books and records relating to the Transferred Assets shall
be maintained by Purchaser or Seller, as the case may be, for a period of seven
(7) years after the Closing Date, unless the parties shall, applicable law
permitting, agree upon a shorter period; provided, however, that in the event
that, as of the end of such period, any taxable year of Purchaser or Seller is
still under examination or open for examination by any taxing authority and that
party has given notice of that fact to the other party, such books and records
shall be maintained (or, alternatively, delivered by the Inspected Party to the
other party) until the date, determined reasonably and in good faith, specified
for maintenance of such records in such notice. Prior to the destruction of any
books and records relating to the Transferred Assets, the party in possession of
such books and records shall offer them to the other party hereto.

          (c)    Seller covenants and agrees that it shall cause to be delivered
to Purchaser, as soon as reasonably practicable after the Closing Date, but in
no event later than ten (10) days following the Conversion Date, fully executed
originals (or, to the extent originals are not available, copies of the fully
executed originals) of (i) each Merchant Agreement included within the
Transferred Assets to which a Top 50 Merchant is a party that Seller has in its
possession (as identified in Section 6.5(b)), (ii) each Agent Bank Agreement,
ISO Agreement and Related Agreement included with the Transferred Assets
assigned to Purchaser pursuant to this Agreement that Seller has in its
possession (as identified in Section 6.5(c)), and (iii) all other Merchant
Agreements included within the Transferred Assets that Seller has in its
possession.

                 CONSIDERATION FOR TRANSFERRED ASSETS; CLOSING

          2.1.   Purchase Price.    As consideration for the Transferred Assets
and Assumed Liabilities, at the Closing, Purchaser shall pay to Seller an amount
equal to $41,985,531 ("Up-Front Purchase Price"), and Purchaser shall retain an
amount equal to $9,238,469 ("Holdback Amount"), in each case such amount to be
paid in lawful currency of the United States by wire transfer (with written wire
transfer instructions to be provided at least 1 day in advance) in immediately
available funds (the sum of the Up-Front Purchase Price plus the Holdback
Amount, plus the value of the Assumed Liabilities, the "Purchase Price").

          2.2.   Allocation of Purchase Price.

          (a)    The Purchase Price shall be allocated among the Transferred
Assets and Assumed Liabilities, such allocation to be made as provided in
Section 1060 of the Code.  Purchaser and Seller shall negotiate in good faith in
an attempt to agree on the allocation of the Purchase Price until the earlier of
(i) the date which is ninety (90) days after the Closing Date or (ii) the date
on which Purchaser and Seller execute and deliver an allocation agreement
reflecting the agreement between Purchaser and Seller on the allocation of the
Purchase Price ("Allocation Agreement").
<PAGE>
 
          (b)   If, after the date of the Allocation Agreement, there is any
decrease in the Purchase Price due to Purchaser making a claim against the
Holdback Amount pursuant to Section 1.4(d) hereof, Purchaser and Seller shall
negotiate in good faith one (1) or more amendments to the Allocation Agreement
covering the allocation of any such decrease in the Purchase Price until the
earlier of (i) the date which is forty-five (45) days after the date on which
such adjustment to the Purchase Price was made, or (ii) the date on which
Purchaser and Seller execute and deliver an amendment to the Allocation
Agreement covering the allocation of any such adjustment to the Purchase Price.

          (c)   If Purchaser and Seller agree on the allocation of the Purchase
Price and execute and deliver the Allocation Agreement and any amendments
thereto within the time limits set forth in Sections 2.2(a) and (b) above, (i)
Purchaser and Seller shall each file on a timely basis Form 8594 (Asset
Acquisition Statement Under Section 1060), including any supplements or
amendments thereto, so as to report the allocation of the Purchase Price
consistent with the Allocation Agreement and any amendments thereto, and (ii)
Purchaser and Seller shall not take any position on their respective income tax
returns that is inconsistent with the allocation of the Purchase Price as agreed
to in the Allocation Agreement and any amendments thereto.

          (d)   If Purchaser and Seller are unable to agree on the allocation of
the Purchase Price and execute and deliver the Allocation Agreement or any
amendments thereto  within the time limits set forth in Sections 2.2(a) and (b)
above, any disputed items shall be referred to KPMG Peat Marwick, or another
independent certified public accounting firm agreed to by Purchaser and Seller,
for resolution.  The decision of such accounting firm as to allocation of the
Purchase Price for the Transferred Assets and the Assumed Liabilities with
respect to any disputed item will be final and binding upon both parties.

          (e)   Neither Purchaser nor Seller shall file any tax returns or, in a
judicial or administrative proceeding, assert or maintain any tax reporting
position that is inconsistent with this Agreement or the allocation agreed to in
accordance with this Agreement, unless required to do so by applicable law.

          2.3.  Closing.    The consummation of the purchase and sale of the
Transferred Assets and assumption of the Assumed Liabilities (the "Closing")
shall take place on December 1, 1998 (the "Closing Date"), or such other date as
the parties may mutually agree upon, to be effective as of the Closing Date, and
shall take place either at the offices of Reed Smith Shaw & McClay LLP, 435
Sixth Avenue, Pittsburgh, Pennsylvania 15219 or through the exchange, via
facsimile to be followed by hard copies via national overnight courier (e.g.,
Federal Express), of executed originals of this Agreement, the Operative
Documents and all other agreements, documents and instruments to be executed in
connection herewith or therewith, or at such other place or by such other method
as may be mutually agreed upon by the parties.

                                 ARTICLE  III

  CONVERSION PERIOD; EMPLOYEE OBLIGATIONS; GOVERNMENT CONTRACTS CERTIFICATION

          3.1.  Orderly Transition.    Seller and Purchaser each covenants and
agrees to use all commercially reasonable efforts to cooperate with each other
to effect an orderly transition of the Merchant Acquiring Business until the
Conversion Date with respect to the Transferred Assets and the Assumed
Liabilities, including but not limited to fulfilling its obligations under
Section 1.3 hereof.  In order to further such purpose, Seller and Purchaser each
agree that until the Conversion Date it shall execute such documents as are
reasonably deemed necessary or convenient by each other to evidence the
agreements referred to in, and transactions contemplated by, this Agreement,
consistent with the rules and regulations of the Credit Card
<PAGE>
 
Associations, EFT Networks and EBT Networks (as applicable) and an orderly
transition of the Transferred Assets used in the Merchant Acquiring Business.

          3.2.  Services During the Conversion Period.    During the Conversion
Period, Seller shall perform on behalf of and for the account of the Purchaser,
the services ("Transitional Services") set forth in an Interim Transaction
Processing Agreement, substantially in the form of Exhibit C hereto (the
"Interim Transaction Processing Agreement").  The Transitional Services shall be
performed by Seller in accordance with the terms and conditions of, and at such
time or times provided in, the Interim Transaction Processing Agreement.

          3.3.  Fees, Revenue and Expenses During the Conversion Period.
During the Conversion Period, Purchaser and Seller shall pay such fees and
expenses, in connection with the performance of the Transitional Services by
Seller as provided in the Interim Transaction Processing Agreement.

          3.4.  Employees.

          (a)   Seller shall use all commercially reasonable efforts to ensure
that the Employees employed by Seller in the Merchant Acquiring Business during
the period prior to Closing ("Merchant Acquiring Business Employees") will
continue in the employ of Seller or its subsidiaries or affiliates, performing
the duties relating to the Transferred Assets used in the Merchant Acquiring
Business therefore performed by them.  Further, Seller shall provide adequate
and appropriate skilled staffing in connection with the operation of the
Transferred Assets and Merchant Acquiring Business during the period prior to
Closing.

          (b)   Prior to the Closing, Seller shall not, unless otherwise
expressly contemplated by this Agreement or any other Operative Document or
consented to in writing by Purchaser:

          (i)   increase the compensation payable to or to become payable to any
     Merchant Acquiring Business Employee listed on Schedule 3.4(c)(ii), unless
     such increase results from the operation of compensation arrangements in
     effect prior to the date of this Agreement (including without limitation
     regularly scheduled merit-based salary increases and bonuses) all of which
     are set forth on Schedule 3.4(c)(ii); and

          (ii)  grant any severance or termination pay (other than pursuant to
     the severance policy of Seller or pursuant to an agreement to which Seller
     is a party and which provides for severance or termination pay as in effect
     on the date of this Agreement) to, or enter into an or amend any employment
     or severance agreement with any Merchant Acquiring Business Employee listed
     on Schedule 3.4(c)(ii).

          (c)   Purchaser's obligations regarding Seller's Employees shall be as
     follows:

          (i)   Schedule 3.4(c)(i) sets forth the following information for each
     Merchant Acquiring Business Employee as of the date hereof:  name, position
     held, current salary grade, official title, 1997 bonus amount, current
     salary, compensation history since January 1, 1998, annual vacation
     entitlement, Fair Labor Standards Act status, date of hire, schedule of
     work, shift differential, if any, work location, and accrued and unused
     1998 vacation.  Such list will indicate which Merchant Acquiring Business
     Employees are Inactive Employees and, to the extent known, the date on
     which each Inactive Employee is expected to return to active employment.

          (ii)  Purchaser shall interview, and, if the interviews are acceptable
     to Purchaser, make written offers of employment on "comparable" (as defined
     herein) terms effective as of the Closing Date to those Merchant Acquiring
     Business Employees listed on
<PAGE>
 
     Schedule 3.4(c)(ii) upon the earlier of (A) thirty (30) days after the date
     of this Agreement or (B) three (3) days prior to the Closing Date ("Signing
     Period"). Seller agrees not to make any effort to retain any Merchant
     Acquiring Business Employee set forth on Schedule 3.4(c)(ii) (including
     making a competing offer) unless and until such Merchant Acquiring Business
     Employee rejects Purchaser's offer of employment; provided that Seller may
     respond to inquiries regarding the consequences of rejecting an offer of
     employment with Purchaser. To the extent any such offer of employment is
     made to any Inactive Employee, such offer of employment shall be effective
     as of the date which is the later of the Closing Date or the date on which
     each such Inactive Employee is able and willing to commence the performance
     of services on a full-time basis; provided, however, that such date occurs
     within six months after the Closing Date. For purposes of this subsection
     3.4(c)(ii), an offer of "comparable" employment shall mean a position with
     Purchaser that: (A) pays a base salary no less than the base salary in
     effect on the day before the Closing Date; (B) provides for eligibility for
     Purchaser's bonus and/or long-term incentive program; and (C) is at a level
     of responsibility and authority determined in good faith by Purchaser not
     to be substantially below that required of the Merchant Acquiring Business
     Employee as of the day before the Closing Date and is consistent with the
     Merchant Acquiring Business Employee's skills, training and work
     experience. All Merchant Acquiring Business Employees who accept employment
     with Purchaser as of the Closing shall be referred to as "Transferred
     Employees". Purchaser may also, from time to time, make offers of
     employment to other Merchant Acquiring Business Employees on such terms as
     Purchaser may elect, and any such Merchant Acquiring Business Employee that
     accepts such offer of employment shall be deemed a Transferred Employee as
     of the effective date of his or her employment by Purchaser.

          (iii)  Transferred Employees shall be eligible to participate as of
     the later of the Closing Date or the effective date of their employment by
     Purchaser in the employee benefit plans and other fringe benefits of
     Purchaser on the same basis as such plans and benefits are offered to
     similarly situated employees of Purchaser.

          (iv)   After the later of the Closing Date or the effective date of
     hire by Purchaser, Purchaser shall pay, discharge and be responsible for
     all obligations relating to each Transferred Employee relating to such
     Transferred Employee's employment by Purchaser, including (x) all salary,
     wages and claims (including, but not limited to, workers compensation
     claims or benefits) and (y) any benefits or contributions under any of
     Purchaser's employee benefit plans and other fringe benefits offered by
     Purchaser arising out of or relating to the employment of the Transferred
     Employees by Purchaser on or after the later of the Closing Date or the
     effective date of hire by Purchaser, including without limitation, any
     continuation coverage required pursuant to Code Section 4980B as a result
     of any "qualifying event" (within the meaning of Code Section 4980B(f)(3))
     occurring with respect to any Transferred Employee (or any spouse or
     dependent of a Transferred Employee) after the Closing Date (or hire date,
     as applicable), other than continuation coverage elected by any such
     Transferred Employee, spouse or dependent under Seller's group health plan
     pursuant to Code Section 4980B.

          3.5.   Clearing Bank Arrangement.

          (a)    In order to permit an orderly transition of the processing of
Credit Card and Debit Card transactions, during the Conversion Period, Seller
shall continue to be a party (fulfilling Member responsibilities) to the
Merchant Agreements, Agent Bank Agreements, ISO Agreements and Related
Agreements included in the Transferred Assets and Seller shall act as a clearing
bank for Purchaser with respect to Credit Card and Debit Card transactions
processed under the Merchant Agreements, Agent Bank Agreements, ISO Agreements
and Related Agreements included in the Transferred Assets all in accordance with
the provisions of the
<PAGE>
 
Transitional Services Agreement and the rules and regulations of the Credit Card
Associations, EFT Networks and EBT Networks, for a period of time ending not
later than the Conversion Date.

          (b)    At the request of Purchaser, Seller shall execute appropriate
documents to evidence the transfer of the clearing bank responsibilities under
the Merchant Agreements, the Agent Bank Agreements, ISO Agreements and/or
Related Agreements included in the Transferred Assets to a Person agreed upon by
Seller and Purchaser.  In addition, Seller shall render such other necessary
assistance as Purchaser may reasonably request.  Seller shall provide to
Purchaser all information necessary for such transfer.

          3.6.   Third Party Service Provider Contracts.

          (a)    Purchaser acknowledges that Seller has in effect the agreements
identified on Schedule 3.6(a) with third party service providers, and that
Seller shall maintain such agreements at least until the Conversion Date, unless
such agreements can be earlier terminated upon mutual agreement of the parties
hereto.  During the Conversion Period, Seller agrees to continue its operational
responsibilities under all of the agreements listed in Schedule 3.6(a) relating
to the Transferred Assets and the Merchant Acquiring Business as Transitional
Services in accordance with the terms and conditions of the Interim Transaction
Processing Agreement.  During the Conversion Period, Purchaser shall pay to
Seller such fees as set forth in the Interim Transaction Processing Agreement
and Seller shall maintain and implement such agreements with third party service
providers, including those identified on Schedule 3.6(a), as necessary to
provide the Transitional Services under the Interim Transaction Processing
Agreement.  In the event Purchaser requires the services of the third party
service providers listed on Schedule 3.6(a) beyond the Conversion Date,
Purchaser agrees to either, at Seller's sole discretion, assume the agreements
from Seller as of the Conversion Date or enter into new agreements with such
third party service providers.

          (b)    With respect to the Buypass Agreement, Purchaser and Seller
agree as follows:

          (i)    between the Closing Date and the Cut-Off Date (as that term is
     defined in the Interim Transaction Processing Agreement), (A) Seller may
     pass on to Purchaser the actual charges for point of sale authorization,
     settlement and other services incurred thereunder ("Usage Fees") in
     accordance with the terms of the Interim Transaction Processing Agreement
     and (B) Purchaser and Seller shall share equally any amounts required to be
     paid in excess of the Usage Fees in connection with any minimum payment
     requirements ("Minimum Fees"); and

          (ii)   after the Cut-Off Date, Seller and Purchaser share equally any
     Minimum Fees or fees paid to terminate or assign the Buypass Agreement.

          3.7.   Conversion.    Purchaser shall use all commercially reasonable
efforts to complete the conversion of the point-of-sale terminals utilized by
Merchants from the Mellon Payment Processing System to Purchaser's network no
later than the Conversion Date, and Seller shall use all commercially reasonable
efforts, until the Conversion Date, to assist Purchaser in such conversion.
Purchaser acknowledges that it is responsible for the direct costs of such
conversion.

          3.8.   Conversion Date.    In no event shall the Conversion Date be
extended beyond September 30, 1999; provided, however, that if reasons,
circumstances or other factors beyond the reasonable control of Purchaser or
Seller shall not allow Purchaser and Seller to cause all processing services
heretofore provided by Seller at Seller's premises (except for clearing,
settlement, or other "Member" services in connection with Section 3.5 and the
maintenance of
<PAGE>
 
certain agreements pursuant to Section 3.6) to be transitioned from Seller's
premises to Purchaser's premises on or prior to the Conversion Date, upon the
agreement of Purchaser and Seller, the Conversion Date may be extended upon such
terms and conditions as each of Purchaser and Seller may agree.

          3.9.   Operation of Business; Other Restrictions.    (a) Prior to the
Closing, Seller shall, unless otherwise expressly contemplated by this Agreement
or any other Operative Document or consented to in writing by Purchaser:

          (i)    operate the Merchant Acquiring Business in the usual and
     ordinary course of business consistent with past practices;

          (ii)   use all commercially reasonable efforts to preserve
     substantially intact the business organization of the Merchant Acquiring
     Business, maintain its material rights and franchises, retain the services
     of its respective officers and employees and maintain its relationships
     with its customers and suppliers;

          (iii)  continue to actively solicit and sign-up new Merchants, Agent
     Banks and Independent Sales Organizations in accordance with past
     practices;

          (iv)   use commercially reasonable efforts to maintain and keep the
     Merchant Acquiring Business properties and assets in as good repair and
     condition as at present, ordinary wear and tear excepted, and maintain
     supplies and inventories consistent with past practices;

          (v)    use commercially reasonable efforts to keep in full force and
     effect insurance and bonds comparable in amount and scope of coverage to
     that maintained by Seller as of the date of this Agreement; and

          (vi)   promptly notify Purchaser of the occurrence of any event which
     reasonably could be expected to cause a Material Adverse Effect.

          (b)    Prior to the Closing, Seller shall not, unless otherwise
expressly contemplated by this Agreement or any other Operative Document or
consented to in writing by Purchaser:

          (i)    sell, lease, exchange, mortgage, pledge, transfer or otherwise
     dispose of, or agree to sell, lease, exchange, mortgage, pledge, transfer
     or otherwise dispose of, any of the Transferred Assets or any interest
     therein, except for dispositions of inventories and of assets in the
     ordinary course of business and consistent with past practices; or

          (ii)   amend, modify or change any Merchant Agreement, Agent Bank
     Agreement, ISO Agreement or Related Agreement included within the
     Transferred Assets.

          (c)    Nothing in this Section 3.9 shall impose any restrictions on,
or otherwise restrict in any way, Seller's ability to operate, perform under,
service, support or dispose of any Excluded Asset or Excluded Liability.

          3.10.  Government Contracts Certification.  Purchaser and Seller shall
work and cooperate with each other and use all commercially reasonable efforts
to (a) obtain the consent of the Financial Management Service to Purchaser
acting as subcontractor to Seller under the Government Contracts, and (b) obtain

Period").  If the
<PAGE>
 
Required Government Certifications have not been obtained prior to the

     [Confidential treatment has been requested for portions of this exhibit
     below, and, accordingly, such portions have been omitted from the exhibit.
     The entire document, including the portions omitted from the exhibit, has
     been provided separately to the Commission.]

          Purchaser shall pay to Seller ____ for each month (or portion thereof)
after ________, but not in excess of two (2) months thereafter, in which Seller
must continue to maintain the operation of its Mellon Payment Processing System
to process the Government Contracts due to either the extension of time from the
First Extension Period or the Second Extension Period; provided, that Seller
must use all commercially reasonable efforts to consummate the conversion of the
Government Contracts on or before ________, and provided further that Purchaser
shall in no event pay to Seller more than ____.

          If the Required Government Certifications have not been obtained by
the end of the Second Extension Period, Seller shall use all commercially
reasonable efforts to sell, transfer and convey the right to provide Merchant
Acquiring Business services as a subcontractor under the Government Contracts to
a Person reasonably acceptable to Seller, and Purchaser shall be entitled to
receive all proceeds therefrom less any reasonable, direct, out-of-pocket, third
party transaction costs incurred by Seller.  Seller agrees to act in a
commercially reasonable fashion with respect to the sale of the right to provide
Merchant Acquiring Business services as a subcontractor under the Government
Contracts taking into account price, the ability of the proposed purchaser to
provide the services required, the certainty of closing, and other similar
factors typically evaluated in connection with similar transactions and consult
with Purchaser regarding the process.

          3.11.  Seller's Employees Related to Government Contracts.   The three
(3) key employees of Seller whose principal function relates to the merchant
processing services under the Government Contracts are set forth on Schedule
3.11 (the "Key Government Employees").  The Key Government Employees shall
remain in the employ, and under the control, of Seller.  Such Key Government
Employees shall perform their services principally for the benefit of Purchaser
and  shall dedicate their full-time attention and efforts to the merchant
processing services provided under the Government Contracts.  The Key Government
Employees shall fully cooperate with Purchaser's management and employees in the
development, implementation, support and marketing of the merchant processing
services provided under the Government Contracts.  Purchaser shall have the
right to raise objections to Seller with respect to the services rendered by any
Key Government Employee if such services are not to the reasonable satisfaction
of Purchaser, and Seller shall promptly and reasonably respond to such
objections. Seller shall bear all costs and expenses with respect to the Key
Government Employees for the first twelve (12) month period after the Closing
Date.  During the second twelve (12) month period after the Closing Date, (a)
Seller shall be responsible for (i) the compensation of such Key Government
Employees, (ii) applicable withholding Taxes from each Key Government Employee's
salary, and (iii)  paying over or depositing such Taxes with the appropriate
governmental agencies and (b)  Purchaser shall reimburse Seller for (i) all
compensation (including Seller's portion of any Taxes that are not withheld from
the Key Government Employees' salaries) and benefits incurred by Seller for such
Key Government Employees and (ii) any direct, out-of-pocket, travel expenses for
the Key Government Employees incurred by Seller that are related to the merchant
processing services function under the Government Contracts.  Notwithstanding
the foregoing, Purchaser's aggregate liability for such expenses shall in no
event exceed $224,000 during the second twelve (12) month period after the
Closing Date and Purchaser's obligations under this Section 3.11 shall expire
upon the earlier of (a) the second anniversary of the Closing Date or (b) the
purchase by Seller of the Purchaser's rights as subprocessor under the
Subprocessed Contracts (as defined in the Marketing Agreement) under the
Marketing Agreement or by another Person as contemplated by Section 3.10.
Purchaser and Seller agree that, if a Key Government Employee's employment with
Mellon is terminated prior to the second anniversary of the Closing Date,
Purchaser and Seller will discuss replacement of such Key Government Employee
and associated expense issues and whether such replacement should be hired by
Seller or Purchaser.  After the second anniversary of the Closing Date,
Purchaser and Seller will negotiate in good faith to determine whether the
functions performed
<PAGE>
 
by the Key Government Employees should be performed by employees of Seller or
employees of Purchaser and associated expense issues.

Credit Card or Debit Card transaction processing services at rates at least as
low as Purchaser provides such services to similar size customers requiring
similar services at similar volumes. If Purchaser fails to accept Seller's offer
within the designated time period, whether because Purchaser cannot provide
competitive pricing, any required functionality or otherwise, Seller shall be
entitled to enter into an agreement with another processor to develop, market
and sell the Integrated Product notwithstanding any provision of this Article
XI. If Purchaser accepts Seller's offer, Seller agrees to market the Integrated
Product with Purchaser performing the merchant acquiring Credit Card or Debit
Card functions; provided, however, if a potential customer for the Integrated
Product is a Person that is not a customer of Purchaser and has previously
engaged another Person to provide transaction processing, Seller may offer such
non-customer an Integrated Product with a third-party transaction processor;
provided, further, Seller shall not actively market such Integrated Product with
a third-party transaction processor to other parties besides such non-customer
in competition with Integrated Products with Purchaser performing the merchant
acquiring Credit Card or Debit Card functions. Furthermore, Seller shall be
entitled to develop, market and sell Stand-Alone Products (as defined below) to
merchant transaction processors besides Purchaser, regardless of whether such
processors integrate the Stand-Alone Products with such processor's acquiring
products and services and then market and sell such integrated products to
merchants, provided such integrated products are not marketed or sold by Seller
or under Seller's name, marks or brand name. Nothing in this Article XI is
intended, or should be construed, to prevent or restrict Seller's ability to
develop, market and sell any other product (the "Stand-Alone Products") that
does not involve or require a merchant acquiring Credit Card or Debit Card
transaction processing function. For example (and for purposes of illustration
only), Seller shall not be prevented from developing, marketing and selling the
following products: smart card issuance and processing, electronic commerce or
"E-commerce," non-credit card processing, digital certificate authorization, on-
line debit point of sale technology, pre-paid debit cards and closed-loop
payment systems.

     (b)  Seller and Purchaser hereby acknowledge and agree that Purchaser and
its Affiliates conduct business and have customers from across the United States
and Canada and that the Goodwill is not restricted to the specific states or
territories in which Purchaser or its Affiliates have offices.  As such, Seller
and Purchaser hereby acknowledge and agree that in order to give full effect to
the purposes of this Article XI, the geographic scope of this Agreement shall
include all of the United States and Canada (the "Territory").

     (c)  If Seller or any Affiliate of Seller acquires control of any business
which has a Merchant Acquiring Business portfolio (the "Target Merchant
Acquiring Business Portfolio") representing $10 billion or less in MasterCard
and Visa processing volume during the twelve (12) month period prior to the date
of the acquisition (the "Acquisition Date"), Seller shall notify Purchaser of
the acquisition of the Target Merchant Acquiring Business Portfolio within
thirty (30) days after the Acquisition Date (the "Acquisition Notice").
Purchaser shall have a right of first refusal to acquire Seller's interest in
the Target Merchant Acquiring Business Portfolio from Seller ("Right of First
Refusal") at a price determined as set forth herein to the extent that Seller is
not (i) prohibited by law or (ii) prohibited by the terms of a contract in
existence prior to the acquisition of the Target Merchant Acquiring Business
Portfolio, between the owner of the Target Acquiring Business Portfolio and a
third-party not an Affiliate of Seller, in each case, from selling its interest
in the Target Merchant Acquiring Business Portfolio to Purchaser.  To determine
the purchase price of the Target ("Target Purchase Price"), Seller and Purchaser
shall first attempt to negotiate the Target Purchase Price.  If, after at least
two face-to-face meetings within thirty (30) days, Seller and Purchaser are
unable to agree on the Target Purchase Price, each shall choose an independent
financial firm with a nationally recognized expertise in evaluating businesses
in the transaction payment processing industry (the "Valuation Expert") within
forty-five (45) days of the receipt by Purchaser of the Acquisition Notice. Each
Valuation Expert shall enter into an agreement with either the Purchaser or the
Seller, as applicable, which shall provide, in part, that the fees and expenses
of such Valuation
<PAGE>
 
Expert shall be borne by the party retaining the Valuation Expert and that each
Valuation Expert shall make a determination of the valuation of the Target (the
"Valuation") no later than thirty (30) days after the date each Valuation Expert
is hired (the "Valuation Date"). If the lower Valuation is 90% or greater of the
higher Valuation, then the average of the two Valuations shall be the Target
Purchase Price. Purchaser may then exercise the Right of First Refusal by
delivery of written notice within ten (10) days of the receipt of written notice
of such determination of the Target Purchase Price. If the lower Valuation is
less than 90% of the higher Valuation, Seller and Purchaser shall jointly choose
a third Valuation Expert, within ten (10) days after the Valuation Date, who
shall make a determination as to Valuation. The third Valuation Expert shall
enter into an agreement with the Purchaser and the Seller which shall provide,
in part, that the fees and expenses of which shall be shared equally by Seller
and Purchaser and that such Valuation Expert shall determine the Valuation of
the Target no later than thirty (30) days after the date such Valuation Expert
is hired (the "Second Valuation Date"). Within five (5) days of the Second
Valuation Date, the three (3) Valuations shall be compared and the average of
the two (2) Valuations that are the closest dollar amount to each other shall be
the Target Purchase Price. Purchaser may then exercise the Right of First
Refusal at the Target Purchase Price by delivery of written notice to Seller
within ten (10) days of the receipt of written notice of the determination of
such Target Purchase Price. The acquisition of Seller's interest in the Target
Merchant Acquiring Business Portfolio by Purchaser shall be subject to customary
due diligence, shall be pursuant to definitive documentation in form and
substance reasonably satisfactory to Seller and Purchaser and shall be
consummated within 180 days of the Acquisition Date unless a later date is
agreed to by Seller and Purchaser. If Purchaser does not exercise its Right of
First Refusal within the applicable time period, Seller shall dispose of its
interest in the Target Merchant Acquiring Business Portfolio within 180 days of
the Acquisition Date (or such later date as agreed to by Seller and Purchaser).
If Seller is prohibited from selling its interest in the Target Merchant
Acquiring Business Portfolio as described above, Seller shall either (i) sell to
another Person or otherwise dispose of its interest in the Target Merchant
Acquiring Business Portfolio, or (ii) if Seller is likewise prohibited from
selling its interest to another Person or otherwise disposing of its interest,
treat the transaction as if a Change of Control has occurred and the provisions
of Section 11.1(e) shall apply.

     (d)  If Seller or any Affiliate of Seller acquires control of a Target
Merchant Acquiring Business Portfolio representing in excess of $10 billion in
MasterCard and Visa processing volume during the twelve (12) month period prior
to the Acquisition Date, Seller shall have the option, exercisable in its sole
discretion within thirty (30) days of the Acquisition Date, to either  (i)
provide Purchaser with written notice of Seller's intent to divest itself of the
Target Merchant Acquiring Business Portfolio, in which case the provisions of
Section 11.1(c) shall apply to the disposition of the Target Merchant Acquiring
Business Portfolio, or (ii)  provide Purchaser with a Termination Notice
regarding its obligations under this Article XI and the Marketing Agreement and
pay the Termination Payment set forth in Section 11.1(e).

     (e)  Upon the occurrence of a Change of Control (as defined herein) or the
Seller providing the Purchaser with the Termination Notice described in Section
11.1(d)(ii) above, Seller may, at its option, within thirty (30) days of the
Change of Control Date, or thirty (30) days of the Acquisition Date (as the case
may be), terminate its obligations under this Article XI and the Marketing
Agreement, by delivery to Purchaser of written notice of its intent to terminate
its obligations under this Article XI and the Marketing Agreement, subject to
the continued processing by Purchaser under the Subprocessed Contracts (the
"Termination Notice") and the termination payment set forth below (the
"Termination Payment"); provided, that Seller may, at its option, deliver to
Purchaser a Termination Notice and a Termination Payment after the sixtieth
(60th) month after the Closing Date for any reason, including but not limited
to, a Change of Control.

By way of illustration only, if the Closing Date is December 1, 1998, Seller
would have the right to buyout of its obligations under this Agreement and the
Marketing Agreement on _________ (i.e., the beginning of the _______ month after
the Closing Date) for $_____________. The Termination Payment as determined from
the foregoing table, in immediately available funds, shall accompany the
Termination Notice.

     (f)  For purposes of this Section 11.1, "Change of Control" shall mean a
change in control of Seller of a nature that would be required to be reported in
response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the
Exchange Act, whether or not Seller is then subject to such reporting
requirement; provided that, without limitation, a Change of Control shall be
deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Exchange Act) is or becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
securities of Seller representing in excess of 50% or more of the combined
voting power of Seller's then outstanding securities; or (ii) stockholders of
Seller approve: (A) a plan of complete liquidation of Seller; (B) an agreement
for the sale or disposition of all or substantially all of the assets of Seller;
or (C) a merger, consolidation or reorganization of Seller with or involving any
other corporation or Person, other than a merger, consolidation or
reorganization that would result in the voting securities of Seller outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into voting securities of the surviving
entity) at least 50% of the combined voting power of the voting securities of
Seller (or such surviving entity) outstanding immediately after such merger,
consolidation or reorganization.

     (g)  Notwithstanding the provisions of this Article XI, Seller and
Purchaser acknowledge and agree that:

             (i)    ownership, directly or indirectly, by Seller of an aggregate
          equity interest of less than 5% and the combined ownership by Seller
          and any Affiliates of Seller of an aggregate equity interest of less
          than 10%, in any business engaged in direct or indirect competition
          with the Merchant Acquiring Business in the Territory shall not be a
          violation of this Article XI;

             (ii)   (A) Seller's Affiliate, Mellon United National Bank, has a
          Merchant Acquiring Business portfolio of approximately 120 Merchants
          which are being processed by a third-party processor, (B) Seller shall
          cause Mellon United National Bank to operate and market such Merchant
          Acquiring Business consistent with past practices using only Mellon
          United National Bank employees, (C) Seller shall not market or solicit
          merchants for Mellon United National Bank's Merchant Acquiring
          Business, (D) Seller shall cause Mellon United Bank's Merchant
          Acquiring Business portfolio to be converted to Purchaser by no later
          than April 1, 2000 (or such later date as Seller and Purchaser may
          agree to in writing), and (E) the maintenance of such Merchant
          Acquiring Business portfolio by Mellon United National Bank shall not
          constitute a violation of the provisions of this Article XI to the
          extent such Merchants are converted by April 1, 2000 (or such later
          date as Seller and Purchaser may agree to in writing);

             (iii)  (A) Seller's Affiliate, Mellon 1st Business Bank and its
          parent, Mellon 1st Business Corporation, have a Merchant Acquiring
          Business portfolio of approximately 230 Merchants which are being
          processed by a third-party processor, (B) Seller shall cause Mellon
          1st Business Bank and Mellon 1st Business Corporation to operate and

          using only Mellon 1st Business Bank and Mellon 1st Business
          Corporation employees, (C) Seller shall not market or solicit
          merchants for Mellon 1st Business Bank's and Mellon 1st Business

<PAGE>
 
       Acquiring Business Portfolio for purposes of this Agreement, (E) Seller

       in Section 11.1(c) such that such Merchants may be converted onto
       Paymentech's processing system by no later than April 1, 2000 (or such
       later date as Seller and Purchaser may agree to in writing) and (F) the
       maintenance of such Merchant Acquiring Business portfolio by Mellon 1st
       Business Bank and Mellon 1st Business Corporation shall not constitute a
       violation of the provisions of this Article XI to the extent such
       Merchants are converted by April 1, 2000 (or such later date as Seller
       and Purchaser may agree to in writing);

          (iv)   To the extent that Purchaser does not obtain the Required
       Government Certifications in accordance with Section 3.10 of this
       Agreement, Seller's sale of the rights to perform Merchant Acquiring
       Business services under the Government Contracts and the resulting
       subprocessing arrangement between Seller and the buyer of such rights to
       perform such Merchant Acquiring Business services under the Government
       Contracts shall not constitute a violation of the provisions of this
       Article XI.

          (v)    To the extent that Seller terminates the subprocessing
       arrangement with Purchaser under the Marketing Agreement with respect to
       a Subprocessed Contract (as that term is defined in the Marketing
       Agreement) and obtains the rights to the performance of Merchant
       Acquiring Business services under that Subprocessed Contract, (A) Seller
       shall be permitted to either (1) perform Merchant Acquiring Business
       services under that Subprocessed Contract or (2) sell the rights to
       perform such Merchant Acquiring Business services under that Subprocessed
       Contract to another Person or otherwise subcontract for the performance
       of such Merchant Acquiring Business services with another Person, and (B)
       such performance by Seller or subcontracting arrangement in connection
       with that Subprocessed Contract shall not constitute a violation of the
       provisions of this Article XI.

          11.2   Confidentiality.  Seller recognizes the proprietary interest of
Purchaser and its Affiliates in the Confidential Information relating to the
Merchant Acquiring Business and the Transferred Assets and agrees that a
material breach of this Article XI shall occur if Seller or its Affiliates,
during the Non-Compete Term, violates the provisions of this Section 11.2.  All
Confidential Information relating to the Merchant Acquiring Business and the
Transferred Assets, whether developed by Seller alone or in conjunction with
others or otherwise, is the property of Purchaser; provided that Purchaser shall
comply with the provisions of Section 5.1 in dealing with such Confidential
Information.  Seller hereby acknowledges and understands that its unauthorized
disclosure of Confidential Information relating to the Merchant Acquiring
Business and the Transferred Assets may result in irreparable injury and damage
to Purchaser and its Affiliates, and Seller acknowledges and agrees that
Purchaser and its Affiliates are entitled to prevent Seller from making
unauthorized disclosures of Confidential Information relating to the Merchant
Acquiring Business and the Transferred Assets.  Therefore, except as may be
otherwise required by applicable law (including without limitation a request
from a regulator of Seller), Seller agrees at all times to hold in strict
confidence and not to disclose the Confidential Information relating to the
Merchant Acquiring Business and the Transferred Assets to any Person other than
to Persons engaged by Purchaser and its Affiliates, and not to use Confidential
Information relating to the Merchant Acquiring Business and the Transferred
Assets in any manner, including for its own benefit or the benefit of a third
party, without the prior written consent of Purchaser or its Affiliates.  If
required by applicable law to disclose such Confidential Information relating to
the Merchant Acquiring Business and the Transferred Assets, Seller will provide
advance notice to Purchaser and use all commercially reasonable efforts to
prevent further disclosure.  In the event that Seller or Seller's
Representatives are requested or required by deposition, interrogatory, request
for documents, subpoena, civil investigative demand or similar process to
disclose any of the Confidential Information, Seller shall provide Purchaser
with prompt written notice of such request or demand so that Purchaser may seek
a protective
<PAGE>
 
order or other appropriate remedy and/or consent in writing to such disclosure.
In the event that such protective order or other remedy is not obtained and the
Purchaser has not consented in writing to such disclosure and Seller or Seller's
Representatives are nonetheless, in the reasonable opinion of Seller's legal
counsel, compelled to disclose the Confidential Information to any tribunal or
else stand liable for contempt, Seller or Seller's Representatives may furnish
only that portion of the Confidential Information that Seller or Seller's
Representatives are legally required to provide as advised by opinion of
Seller's legal counsel; provided, that Seller or Seller's Representatives shall
exercise all commercially reasonable efforts to obtain an order or reasonable
assurance that confidential treatment shall be accorded such Confidential
Information. Seller or Seller's Representatives shall not be liable for the
disclosure to such tribunal unless such disclosure was caused or resulted from a
previous disclosure by Seller or Seller's Representatives not permitted
hereunder.

          11.3   Remedies.  In the event of a breach or a threatened breach of
any of the covenants contained in this Article XI, Purchaser and its Affiliates
shall, in addition to the remedies provided by law, have the right and remedy to
have such covenants specifically enforced by a court having equity jurisdiction,
it being acknowledged and agreed that any material breach of any of the
covenants will cause irreparable injury to Purchaser and its Affiliates and that
money damages will not provide an adequate remedy to Purchaser and its
Affiliates.

          11.4   Enforceability/Reformation.  If any court of competent
jurisdiction determines that any of the covenants of Seller or Purchaser, or any
parts thereof, are invalid or unenforceable, the other covenants and the
remainder of any of the covenants so impaired shall not thereby be affected and
shall be given full effect, without regard to the invalid portions.
Notwithstanding the foregoing, it is the intent of each of the parties that the
provisions of Sections 11.1 and 11.2 of this Agreement be enforced to the
fullest extent permitted by applicable law. If any court of competent
jurisdiction determines that any of the provisions of Sections 11.1 and 11.2 of
this Agreement, or any parts thereof, are unenforceable under applicable laws or
public policies, it is the intent of the parties, and the parties hereby
request, that the court reform such covenant to such narrower geographic scope,
scope of activity or duration, or in such other manner, as such court may
determine is necessary to make such covenant enforceable.

          11.5   Waiver.  The failure of any party to insist, in any one or more
instances, upon performance of any of the terms or conditions of this Article XI
shall not be construed as a waiver of future performance of any such term or
condition, and the obligations of any party with respect thereto shall continue
in full force and effect.

          11.6   Continuing Obligations.  If Seller terminates its obligations
under this Article XI and the Marketing Agreement pursuant to Section 11.1(c) or
11.1(d) above prior to end of the eighteenth month after the Closing Date,
Seller agrees that, notwithstanding such termination, Seller shall not, and
Seller shall cause its Affiliates not to, directly or indirectly, market, sell
or provide any Merchant Acquiring Business products or services to any Merchant,
Agent Bank, Independent Sales Organization or Related Party that is a party to a
Merchant Agreement, Agent Bank Agreement, ISO Agreement or Related Agreement
included within the Transferred Assets for a period ending on the last day of
the eighteenth month after the Closing Date.

                                 ARTICLE  XII

and/or Section 4.5, (viii) the failure of Seller to have executed originals (or
accurate copies thereof) of any Merchant Agreement, Agent Bank Agreements, ISO
Agreements or Related Agreements, or (ix) any liability with respect to the Key
Government Employees. In the event that indemnification is sought hereunder by
any member of Purchaser Protected Parties, Purchaser shall act on behalf thereof
and Seller shall be entitled to rely upon the acts and representations of
Purchaser as representing the acts and representations of such member.

          12.2.  Purchaser's Indemnification.    Purchaser shall indemnify,
defend, and hold harmless Seller and its successors or assigns and their
respective officers, employees, consultants, agents and representatives
(collectively, "Seller Protected Parties") from any Loss that results from or

in this Agreement or any certificate delivered in connection herewith; (ii) the
breach of any of Purchaser's covenants or agreements in this Agreement or any
certificate delivered in connection herewith; (iii) the Assumed Liabilities;
(iv) the compliance by Seller with Purchaser's instructions to Seller in
connection with the provision by Seller of the services under Article III, or as
may otherwise arise in connection with Seller's performance of its obligations
under Section 3.5, except as may result from or arise out of the gross
negligence or willful misconduct of Seller; (v) the gross negligence or willful
misconduct of Purchaser in undertaking its obligations under Section 5.4; (iv)
any liability of Purchaser with respect to the Transferred Employees arising on
or after the Closing Date; (v) all liabilities of Purchaser for Taxes

accrued in any period after the Closing Date; (vii) all other liabilities and
obligations or Purchaser relating to the Transferred Assets and Transferred

a Loss as a result from or arising out of such gross negligence or willful
misconduct by Purchaser in connection with any of Seller's agreements relating
to the Merchant Acquiring Business with the third party service providers
identified on Schedule 3.6(a).  In the event that indemnification is sought
hereunder by any member of Seller Protected Party, Seller shall act on behalf of
and Purchaser shall be entitled to rely upon the acts and representations of
Seller as representing the acts and representations of such member.

          12.3.  Indemnification Procedures for Third Party Claims.   In any
case where a Person shall seek indemnification under this Agreement (the
"Indemnified Party"), for a third party claim, suit or proceeding (a "Third
Party Claim"), the Indemnified Party shall comply with the following procedures:

          (a)    The Indemnified Party shall give prompt written notice
("Notice") of any Third Party Claim to the party from whom such indemnification
is sought (the "Indemnifying Party"), specifying the amount and nature of such
Third Party Claim.

          (b)    Provided that prompt Notice is given, unless the failure to
give such Notice does not prejudice the interests of the Indemnifying Party, the
Indemnifying Party shall promptly defend, contest, and protect the Indemnified
Party against such Third Party Claim, at its own
<PAGE>
 
expense and using counsel of its own choosing, which shall be reasonably
satisfactory to the Indemnified Party.

           (c)   The Indemnified Party may, but shall not be obligated to,
participate in the defense of such Third Party Claim at its own expense and
using counsel of its own choosing, but the Indemnifying Party shall be entitled
to control the defense thereof unless the Indemnified Party shall relieve the
Indemnifying Party from all liability for such Third Party Claim.  The
Indemnified Party shall cooperate and provide such assistance as the
Indemnifying Party reasonably may request in connection with the Indemnifying
Party's defense and shall be entitled to recover from the Indemnifying Party the
reasonable costs of providing such assistance.  The Indemnifying Party shall
inform the Indemnified Party on a regular basis, and at the Indemnified Party's
request, of the status of such Third Party Claim and the Indemnifying Party's
defense thereof.

          (d)    If the Indemnifying Party shall control the defense of a Third
Party Claim, the Indemnifying Party shall not compromise or settle such Third
Party Claim without the Indemnified Party's prior written consent, if:  (i) such
compromise or settlement would impose an injunction or other equitable relief
upon the Indemnified Party; or (ii) such compromise or settlement does not
include the unconditional release of the Indemnified Party from all liability
arising from or relating to such Third Party Claim.

          (e)    If the Indemnifying Party fails promptly to defend, contest, or
otherwise protect against such Third Party Claim, the Indemnified Party may, but
shall not be obligated to, defend, contest, or otherwise protect itself against
the same, and make any compromise or settlement thereof in its sole discretion,
and recover from the Indemnifying Party all Losses of the Indemnified Party
arising from or relating to such compromise or settlement.

          12.4.  Indemnity Claims.

          (a)    The representations and warranties contained herein, in any
other Operative Document, or in any certificate or other document delivered
pursuant hereto or in connection herewith shall not be extinguished by the

this Section 12.4 and Section 12.5 hereof, and the covenants and agreements of
Seller and Purchaser contained herein shall survive without limitation as to
time except as may be otherwise specified herein.

          (b)    All claims for indemnification hereunder (including, without
limitation, Third Party Claims) shall be asserted no later than 12 months after
the Conversion Date, except for claims relating to Taxes which may be asserted

nor shall any single or partial exercise of any other right, power or privilege
hereunder.

          14.9.  Severability of Provisions.   If any provision of this

          14.15. Arbitration.

          The parties each hereby waive any right to trial by jury and agree
that any claim or controversy (including without limitation any claim based on
or arising from an alleged tort, breach of contract, strict liability or other
theory of liability) other than a claim for injunctive relief ("Dispute')
arising out of this Agreement or any other Operation Document shall be resolved
in accordance with the following procedures.  The parties shall endeavor in good
faith to promptly, reasonably, and equitably settle all Disputes on an informal
basis in the normal course of business.  All Dispute which the parties cannot so
settle in the normal course of business shall be negotiated and arbitrated in
accordance with the following terms:

          (a)    Either party (the "Initiating Party") may commence a
negotiation of a Dispute by serving on the other party (the "Responding Party")
a written statement of the nature and substance of the Dispute, a brief summary
of its position with respect to the Dispute, its justifications therefor, and
its proposal for resolution of the Dispute. Within ten (10) days, the Responding
Party shall prepare and serve on the Initiating Party a written statement of its
position in response. These position papers may be served by facsimile
transmission or such other means and to such addressees as the parties may
designate from time to time ("Executives"). Within fourteen (14) days of
exchanging position papers, the parties shall conduct a face-to-face meeting of
the Executives and appropriate members of their respective management teams with
knowledge of the matters underlying the Dispute and full authority to resolve
the Dispute. The first such meeting shall be held at the office of the
Responding Party, with succeeding meetings rotated between the parties' offices,
or at such other locations as the parties may agree. The Executives shall
conduct not less than two (2) meetings over a two-week period. If the Executives
cannot agree to a resolution of the Dispute within five (5) days thereafter,
they may continue discussions or either party may refer the Dispute to the next
senior levels of management (hereinafter collectively referred to as the "Senior
Executives"). The Senior Executives, along with such of their subordinates who
have personal knowledge of the Dispute, shall meet initially within five (5)
days of the referral in an effort to resolve the Dispute. The initial meeting
may take place by conference telephone call. The Senior Executives shall have
full authority to settle the Dispute and shall not be limited to the proposed
settlements set forth in the position papers. The Senior Executives may conduct
subsequent face-to-face meetings which shall be rotated between their respective
offices, commencing at the office of the Responding Party, or at such other
locations as the parties may agree. The Senior Executives shall conduct not less
than two (2) such face-to-face meetings over the ensuing 30-day period. If the
Dispute is not resolved within ten (10) days of the second such meeting, the
parties may continue discussions or either party may invoke the arbitration
procedures set forth hereafter by giving notice to the other party.

          (b)    The parties agree that any Dispute between Purchaser and Seller
arising out of or relating to this Agreement or any Operative Document shall, at
the request of either party after exhaustion of the procedures set forth in
Section 14.15(a) above, be determined by arbitration.  Any arbitration
proceedings shall be conducted in Denver, Colorado, unless a different location
is agreed to between the Parties.  The arbitration shall be conducted in
accordance with the United States Arbitration Act (Title 9, U.S. Code),
notwithstanding any
<PAGE>
 
choice of law provision in this Agreement, and under the Commercial Rules of the
American Arbitration Association. The arbitrator(s) shall give effect to
statutes of limitation and the provisions of this Agreement and the Operative
Documents in determining any Dispute. Any controversy concerning whether an
issue is arbitrable shall be determined by the arbitrator(s). The award rendered
by the arbitrator(s) shall set forth findings of facts and conclusions of law
and shall be final, and the judgment may be entered in any court having
jurisdiction thereof. A failure by the arbitrator(s) to make findings of fact
and conclusions of law shall be grounds for overturning the award. The
institution and maintenance of an action for judicial relief or pursuit of a
provisional or ancillary remedy shall not constitute a waiver of the right of
any party, including the plaintiff, to submit the Dispute or claim to
arbitration if any other party contests such action for judicial relief.

          (c)    In any arbitration proceeding, the arbitrator(s) is (are)
authorized to apportion costs and expenses, including investigation, legal and
other expense.  Such costs and expenses are to be awarded only after the
conclusion of the arbitration and will not be advanced during the course of such
arbitration.
