Common Stock outstanding, could be deemed to be beneficially owned pursuant to
the Stockholder Agreement described in this Schedule 13D.  See Item 4.  Each
Reporting Person disclaims beneficial ownership of such shares.
<PAGE>
 
Item 1.  Security and Issuer
- ----------------------------

     The class of equity securities to which this Schedule 13D relates is the
common stock, par value $.01 per share ("Company Common Stock"; shares of
Company Common Stock being hereinafter referred to as the "Shares"), of
Paymentech, Inc., a Delaware corporation (the "Company").  The Company's
principal executive offices are located at 1601 Elm Street, 9th Floor, Dallas,
Texas 75201.

Item 2.  Identity and Background
- --------------------------------

     This Schedule 13D is being filed jointly by each of (i) First Data
Corporation, a Delaware corporation ("First Data"), (ii) FDC Offer Corporation,
a Delaware corporation and a wholly-owned subsidiary of First Data ("Holdco"),
and (iii) FB Merging Corporation, a Delaware corporation and wholly-owned
subsidiary of Holdco ("Merger Sub" and, together with First Data and Holdco, the
"Reporting Persons").  The principal business address of each of the Reporting
Persons is 5660 New Northside Drive, Suite 1400, Atlanta, Georgia 30328.

     First Data operates in three principal business segments providing high-
quality, high-volume information processing and related services to several
market sectors:  payment instruments, card issuer services and merchant
processing services, representing approximately 90% and 80% of First Data's
revenues in 1998 and 1997, respectively.  Each of Holdco and Merger Sub is a
newly incorporated Delaware corporation.  To date, neither Holdco nor Merger Sub
has conducted any business other than that incident to its formation and the
execution and delivery of the Merger Agreement and the Stockholder Agreement, as
hereinafter described.

     Certain information required by this Item 2 concerning the directors and
executive officers of the Reporting Persons is set forth on Annex I attached
hereto, which is incorporated herein by reference.

     During the last five years, none of First Data, Holdco or Merger Sub and,
to their best knowledge, none of the persons listed in Annex I hereto has been
(i) convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors), or (ii) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

Item 3.  Source and Amount of Funds or Other Consideration
- ----------------------------------------------------------

          None of the Reporting Persons has acquired any Shares as of the date
hereof.  The Stockholder Agreement described in Item 4 of this Schedule 13D was
entered into by the Reporting Persons, BANK ONE CORPORATION, a Delaware
corporation ("Bank One"), and First USA Financial, Inc., a Delaware corporation
and wholly-owned subsidiary of Bank One 

                                 (Page 5 of 9)
<PAGE>
 
("First USA"), as an inducement to First Data and Merger Sub to enter into the
Merger Agreement described in Item 4. Except as set forth in the preceding
sentence, none of the Reporting Persons has paid any consideration in connection
with entering into the Stockholder Agreement.

           As indicated in Item 4, one or more of the Reporting Persons may in
the future acquire Shares of the Company.  Holdco may obtain Shares from First
USA in exchange for shares of capital stock of Holdco and Merger Sub may obtain
shares from stockholders other than First USA in exchange for payment of the
Merger Consideration (as hereinafter defined).  If undertaken, funds for such
acquisitions may come from a variety of sources, including the working capital
of First Data or funds from newly issued indebtedness of First Data or the
proceeds thereof.   Pursuant to each of the Merger Agreement and the Stockholder
Agreement described in Item 4, First Data will contribute to Holdco cash in the
amount necessary for the payment of the aggregate Merger Consideration, and each
of First Data and First USA will cause Holdco to contribute to Merger Sub all of
the Shares it receives from First USA and all of the cash it receives from First
Data.  The Merger Consideration will be paid to stockholders (other than Merger
Sub) by the Surviving Corporation (as hereinafter defined).

Item 4.  Purpose of Transaction
- -------------------------------

           On March 22, 1999, First Data, Merger Sub and the Company entered
into an Agreement and Plan of Merger (the "Merger Agreement") providing for the
acquisition by First Data of all of the outstanding Shares other than Shares
owned by Bank One and its subsidiaries. Pursuant to the Merger Agreement, among
other things, Merger Sub will be merged with and into the Company (the
"Merger"), with the Company continuing as the surviving corporation (the
"Surviving Corporation"). As a result of the Merger, all of the issued and
outstanding Shares (other than Shares owned by the Company, First Data, Bank
One, Holdco or any of their respective subsidiaries) will be converted into the
right to receive $25.50 in cash per Share (the "Merger Consideration"). Pursuant
to the Merger Agreement, (i) the directors of Merger Sub at the effective time
of the Merger will become directors of the Surviving Corporation, and (ii) the
officers of the Company at the effective time of the Merger will be the officers
of the Surviving Corporation.

           Consummation of the Merger is conditioned upon, among other things,
approval of the Merger by holders of a majority of the outstanding Shares, which
majority shall, unless otherwise agreed by the Company, First Data and Bank One,
include not less than 66  % of the outstanding Shares not owned directly or
indirectly by Bank One, First Data or their respective affiliates or associates
including, without limitation, Holdco and Merger Sub.  First USA currently owns
approximately 55% of the economic interest and the voting power of the Company
Common Stock and has agreed to vote its Shares in favor of the Merger.  See the
description of the Stockholder Agreement below.

                                 (Page 6 of 9)
<PAGE>
 
           It is anticipated that, as a result of the Merger, the Company Common
Stock will be delisted from the New York Stock Exchange and terminated from
registration pursuant to Section 12(g)(4) of the Securities Exchange Act of
1934, as amended.  A copy of the Merger Agreement is included as Exhibit 99(a)
hereto and the description of the Merger Agreement contained herein is qualified
in its entirety by reference to such exhibit, which is incorporated by
reference.

           Concurrently with the execution of the Merger Agreement, in order to
induce First Data and Merger Sub to enter into the Merger Agreement, the
Reporting Persons, Bank One and First USA entered into the Stockholder Agreement
(the "Stockholder Agreement").  First USA is the owner of 19,979,081 Shares (the
"First USA Shares"), representing approximately 55% of the outstanding Shares.
Pursuant to the Stockholder Agreement, among other things, First USA has agreed
to vote the First USA Shares in favor of the Merger Agreement and the approval
of the Merger and generally to vote the First USA Shares against any of the
following involving the Company or any of its subsidiaries or affiliates (other
than the Merger and the transactions contemplated by or required to implement
the Merger Agreement, the Stockholder Agreement and the Contribution Agreement):
(i) any extraordinary corporate transaction (such as a merger or other business
combination), (ii) any sale, transfer or disposition of any assets outside the
ordinary course of business, or (iii) any reorganization, recapitalization,
dissolution or liquidation.  Pursuant to the Stockholder Agreement, Bank One and
First Data have agreed to combine their ownership interest in the Company.

           A copy of the Stockholder Agreement is filed as Exhibit 99(b) hereto
and the description contained herein is qualified in its entirety by reference
to such exhibit, which is incorporated herein by reference.

           In addition, on March 22, 1999, Bank One and First Data entered into
a Contribution Agreement pursuant to which, following the Merger, the Company
will contribute substantially all of its assets and liabilities to Banc One
Payment Services, L.L.C., the existing merchant bank alliance between Bank One
and First Data (the "Alliance"), in exchange for a membership interest in the
Alliance.

           A copy of the Contribution Agreement is filed as Exhibit 99(c) hereto
and the description contained herein is qualified in its entirety by reference
to such exhibit, which is incorporated herein by reference.

Item 5.  Interest in Securities of the Issuer.
- --------------------------------------------- 

           By reason of the Stockholder Agreement described in Item 4, the
Reporting Persons may be deemed to be beneficial owners of the First USA Shares
and may be deemed to have shared power to vote or direct the vote of the First
USA Shares or shared power to dispose or direct the disposition of the First USA
Shares.  The First USA Shares represent approximately 55% of the outstanding
Shares, based upon the number of Shares outstanding at the close of 

                                 (Page 7 of 9)
<PAGE>
 
business on January 30, 1999. Because of the limited nature of the Stockholder
Agreement, each Reporting Person expressly disclaims beneficial ownership of the
First USA Shares.

           Except as described in this Schedule 13D, none of the Reporting
Persons nor, to the best of their knowledge, any of the persons listed in Annex
I hereto beneficially owns any shares of Company Common Stock.  Except as
described in this Schedule 13D, none of the Reporting Persons nor, to the best
of their knowledge, any of the persons listed in Annex I hereto has effected any
transactions in Company Common Stock during the past 60 days.

Item 6.  Contracts, Arrangements, Understanding or Relationships with Respect to
- --------------------------------------------------------------------------------
Securities of the Issuer.
- ------------------------

          AGREEMENT AND PLAN OF MERGER, dated as of March 22, 1999 (this
"Agreement"), among First Data Corporation, a Delaware corporation ("Parent"),

("Holdco") and a wholly-owned subsidiary of Parent, and Paymentech, Inc., a
Delaware corporation (the "Company") (Merger Sub and the Company being
hereinafter collectively referred to as the "Constituent Corporations").

                             W I T N E S S E T H:

          WHEREAS, BANK ONE CORPORATION, a Delaware corporation ("Bank One"),
through its wholly-owned subsidiary First USA Financial, Inc., a Delaware

          WHEREAS, the respective Boards of Directors of Parent, Merger Sub and
the Company have approved and declared advisable this Agreement and the
transactions contemplated hereby, including the merger of Merger Sub into the
Company (the "Merger"), upon the terms and subject to the conditions set forth
herein, whereby each issued and outstanding Share not owned directly or
indirectly by Parent, Bank One, the Company or any of their Subsidiaries
(including, without limitation, Merger Sub) (other than such Shares held by
Parent, Bank One, the Company or any of their Subsidiaries in a fiduciary,
collateral, custodial or similar capacity which will be converted) will be
converted into the right to receive from the Surviving Corporation (as
hereinafter defined) in cash, without interest $25.50 per Share (the "Merger
Consideration") and the respective Boards of
<PAGE>
 
Directors of Merger Sub and the Company have approved and declared advisable
this Agreement;

          WHEREAS, in order to induce Parent and Merger Sub to enter into this
Agreement, concurrently herewith Parent, Holdco, Merger Sub, Bank One and First
USA are entering into a Stockholder Agreement dated as of the date hereof (the
"Stockholder Agreement") in the form of the attached Exhibit A whereby, among
other things, First USA has agreed to contribute to Holdco the Shares it owns in
exchange for shares of capital stock of Holdco and to vote in favor of the
adoption of this Agreement;

          WHEREAS, pursuant to the Stockholder Agreement, Parent has agreed to
contribute to Holdco sufficient cash to pay the aggregate Merger Consideration
in accordance with Section 1.6 in exchange for shares of capital stock of
Holdco, and each of Parent and First USA has agreed to cause Holdco to
contribute to Merger Sub all of the Shares it receives from First USA and all of
the cash it receives from Parent pursuant to the Stockholder Agreement; and

          WHEREAS, Parent has entered into a Contribution Agreement dated as of
the date hereof (the "Contribution Agreement") with Bank One in the form of the
attached Exhibit B which provides, among other things, that following the Merger
Parent and Bank One, through Holdco, will cause substantially all of the assets
and liabilities and business of the Company, as the Surviving Corporation (as
hereinafter defined), to be contributed to Bank One Payment Services, L.L.C., a
Delaware limited liability company and an alliance between wholly-owned
subsidiaries of Parent and Bank One (the "Alliance"), in exchange for the
issuance to the Surviving Corporation of a membership interest in the Alliance.

          NOW, THEREFORE, in consideration of the premises, representations,
 warranties and agreements herein contained, the parties agree as follows:

                                   ARTICLE I

                                  THE MERGER

          Section 1.1  Contributions of Cash and Shares to Holdco.  Pursuant to
the Stockholder Agreement, immediately prior to the transfers referred to in the
last sentence of this Section 1.1, Parent will contribute to Holdco cash in the
amount necessary for the payment of the aggregate Merger Consideration pursuant
to Section 1.6, and simultaneously therewith First USA will contribute to Holdco
all of the Shares it owns
<PAGE>
 
(other than such Shares held in a fiduciary, collateral, custodial or similar
capacity), in each case in exchange for shares of common stock of Holdco. At
that time each of Parent, Bank One and First USA will execute that certain
stockholder agreement relating to the governance of Holdco and the Company.
Immediately following such transfers and immediately prior to the Effective Time
each of Parent and First USA will cause Holdco to contribute to Merger Sub all
of the Shares it receives from First USA and all of the cash it receives from
Parent in exchange for shares of capital stock of Merger Sub (in an amount to be
agreed upon between Parent and First USA).

          Section 1.2  The Merger.  Upon the terms and subject to the conditions
hereof, and in accordance with the General Corporation Law of the State of
Delaware, as amended (the "DGCL"), Merger Sub shall be merged into the Company
at the Effective Time (as hereinafter defined). Following the Merger, the
separate corporate existence of Merger Sub shall cease and the Company shall
continue as the surviving corporation (the "Surviving Corporation") and shall
succeed to and assume all the rights and obligations of Merger Sub and the
Company in accordance with the DGCL. Notwithstanding anything to the contrary
herein, at the joint election of Parent and Bank One, any direct or indirect
jointly-owned Subsidiary (as hereinafter defined) of Parent and Bank One may be
substituted for Merger Sub as a constituent corporation in the Merger. In such
event, the parties agree to execute an appropriate amendment to this Agreement,
in form and substance reasonably satisfactory to Parent, Bank One and the
Company, in order to reflect such substitution; provided, however, that no such
substitution shall (i) alter or change the amount or kind of consideration to be
received by the holders of Shares in the Merger or (ii) materially delay receipt
of any approval referred to in this Agreement or the consummation of the
transactions contemplated hereby.

          Section 1.3  Effective Time.  The Merger shall become effective when a
certificate of merger (the "Certificate of Merger"), executed in accordance with
the relevant provisions of the DGCL, is filed with the Secretary of State of the
State of Delaware, or at such other time as Merger Sub and the Company shall
agree and as specified in the Certificate of Merger. When used in this
Agreement, the term "Effective Time"
<PAGE>
 
shall mean the later of the date and time at which the Certificate of Merger is
duly filed with the Secretary of State of the State of Delaware or such later
time established by the Certificate of Merger. The filing of the Certificate of
Merger shall be made prior to or on the date of the Closing (as hereinafter
defined).

          Section 1.4  Effects of the Merger.  The Merger shall have the effects
set forth in the applicable provisions of the DGCL.

          Section 1.5  Charter and By-laws; Directors and Officers.  (a) At the
Effective Time, the Certificate of Incorporation of the Company, as amended (the
"Company Charter"), as further amended to read in its entirety as indicated on
the attached Exhibit C, shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter changed or amended as provided therein or
by applicable law. At the Effective Time, the By-laws of Merger Sub, as in
effect immediately prior to the Effective Time, shall be the By-laws of the
Surviving Corporation until thereafter changed or amended as provided therein or
by the Company Charter.

          (b)  The directors of Merger Sub at the Effective Time of the Merger
shall be the directors of the Surviving Corporation, until the earlier of their
resignation or removal or until their respective successors are duly elected and
qualified, as the case may be. The officers of the Company at the Effective Time
of the Merger shall be the officers of the Surviving Corporation, until the
earlier of their resignation or removal or until their respective successors are
duly elected and qualified, as the case may be.

          Section 1.6  Conversion of Securities.  As of the Effective Time, by
virtue of the Merger and without any action on the part of Merger Sub, the
Company or the holders of any securities of the Constituent Corporations:

          (a)  Capital Stock of Merger Sub.  Each issued and outstanding share
of common stock of Merger Sub shall be converted into one validly issued, fully
paid and nonassessable share of common stock of the Surviving Corporation.

          (b)  Treasury Shares, Parent Owned Shares, Bank One Shares. All Shares
that are held in the treasury of the Company or by any wholly-
<PAGE>
 
owned Subsidiary of the Company and any Shares owned by Parent, Bank One or
Merger Sub or by any wholly-owned Subsidiary of Parent or Bank One (other than
such Shares held in a fiduciary, collateral, custodial or similar capacity)
shall be canceled and no capital stock of Parent or other consideration shall be
delivered in exchange therefor.

          (c)  Conversion of Shares.  Each Share issued and outstanding
immediately prior to the Effective Time (other than shares to be canceled in
accordance with Section 1.6(b) and other than Dissenting Shares (as hereinafter
defined)) shall be converted into the right to receive from the Surviving
Corporation the Merger Consideration. All such Shares, when so converted, shall
no longer be outstanding and shall automatically be canceled and retired and
each holder of a certificate representing any such Shares shall cease to have
any rights with respect thereto, except the right to receive the Merger
Consideration, less any applicable withholding taxes, upon surrender of the
Certificate (as hereinafter defined) that formerly evidenced such Shares in the
manner provided in Section 1.7.

          (d)  Shares of Dissenting Stockholders.  Notwithstanding anything in
this Agreement to the contrary, any issued and outstanding Shares held by a
person (a "Dissenting Stockholder") who has not voted in favor of the Merger or
consented thereto in writing and who shall have demanded properly in writing
appraisal for such Shares in accordance with Section 262 of the DGCL and
otherwise complies with all of the provisions of the DGCL concerning the right
of holders of Shares to require appraisal of their Shares ("Dissenting Shares")
shall not be converted into or represent the right to receive the Merger
Consideration, unless such stockholder fails to perfect or withdraws or loses
its right to appraisal. Such stockholders shall be entitled to receive payment
of the appraised value of such Shares held by them in accordance with the
provisions of such Section 262, except that all Dissenting Shares held by
stockholders who shall have failed to perfect or who effectively shall have
withdrawn or lost their rights to appraisal of such Shares under such Section
262 shall thereupon 
<PAGE>
 
be deemed to have been converted into and to have become exchangeable for, as of
the Effective Time, the right to receive the Merger Consideration, without any
interest or dividends thereon, upon surrender of the Certificate or Certificates
that formerly evidenced such Shares in the manner provided in Section 1.7. The
Company shall give Parent and Bank One (i) prompt notice of any demands for
payment received by the Company, withdrawals of such demands and any other
instruments served pursuant to the DGCL and received by the Company and (ii) the
opportunity to participate in and direct all negotiations and proceedings with
respect to any such demand for appraisal under the DGCL. The Company shall not,
without the prior written consent of Parent and Bank One, voluntarily make any
payment with respect to, or settle, offer to settle or otherwise negotiate, any
such demands.

          Section 1.7  Exchange of Certificates.  (a) Paying Agent. Prior to the
Effective Time, Parent shall designate First Chicago Trust Company of New York
(or such other person or persons as shall be reasonably acceptable to Parent,
Bank One and the Company) to act as paying agent in the Merger (the "Paying
Agent"), and at the Effective Time, Merger Sub shall make available to the
Paying Agent cash in the amount necessary for the payment of the Merger
Consideration upon surrender of certificates representing Shares as part of the
Merger pursuant to this Section 1.7. Any and all interest earned on funds made
available to the Paying Agent pursuant to this Agreement shall be paid over to
Parent.

          (b)  Exchange Procedure. As soon as reasonably practicable after the
Effective Time, the Paying Agent shall mail to each holder of record of a
certificate or certificates that immediately prior to the Effective Time
represented Shares (the "Certificates"), (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Paying
Agent and shall be in a form and have such other provisions as Parent may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the Merger Consideration.
<PAGE>
 
Upon surrender of a Certificate for cancellation to the Paying Agent or to such
other agent or agents as may be appointed by Parent, together with such letter
of transmittal, duly executed, and such other documents as may reasonably be
required by the Paying Agent, the holder of such Certificate shall be entitled
to receive in exchange therefor the amount of cash into which the Shares
theretofore represented by such Certificate shall have been converted pursuant
to Section 1.6, and the Certificate so surrendered shall forthwith be canceled.
In the event of a transfer of ownership of Shares that is not registered in the
transfer records of the Company, payment may be made to a person other than the
person in whose name the Certificate so surrendered is registered, if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of such Certificate or establish to the satisfaction of the Surviving
Corporation that such tax has been paid or is not applicable.

Until surrendered as contemplated by this Section 1.7, each Certificate (other
than Certificates representing Dissenting Shares) shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the amount of cash, without interest, into which the Shares
theretofore represented by such Certificate shall have been converted pursuant
to Section 1.6. No interest will be paid or will accrue on the cash payable upon
the surrender of any Certificate. Parent or the Paying Agent shall be entitled
to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement such amounts as Parent or the Paying Agent is required to deduct and
withhold with respect to the making of such payment under the Code (as
hereinafter defined) or under any provisions of state, local or foreign tax law.
To the extent that amounts are so withheld by Parent or the Paying Agent, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the person in respect of which such deduction or withholding was
made by the Parent or the Paying Agent and any such amounts deducted or withheld
shall be promptly and timely paid by Parent or the Paying Agent to the
appropriate taxing authority.

          (c)  No Further Ownership Rights in Shares.  All cash paid upon the
surrender of Certificates in accordance with the terms of this 
<PAGE>
 
Article I shall be deemed to have been paid in full satisfaction of all rights
pertaining to the Shares theretofore represented by such Certificates. At the
Effective Time, the stock transfer books of the Company shall be closed, and
there shall be no further registration of transfers on the stock transfer books
of the Surviving Corporation of the Shares that were outstanding immediately
prior to the Effective Time. If, after the Effective Time, Certificates are
presented to the Surviving Corporation or the Paying Agent for any reason, they
shall be canceled and exchanged as provided in this Article I.

          (d)  Termination of Payment Fund.  Any portion of the funds made
available to the Paying Agent to pay the Merger Consideration which remains
undistributed to the holders of Shares for six months after the Effective Time
shall be delivered to Parent, upon demand, and any holders of Shares who have
not theretofore complied with this Article I and the instructions set forth in
the letter of transmittal mailed to such holders after the Effective Time shall
thereafter look only to Parent for payment of the Merger Consideration to which
they are entitled, without interest or dividends.

          (e)  No Liability.  None of Parent, Holdco, Merger Sub, the Company or
the Paying Agent shall be liable to any person in respect of any cash delivered
to a public official pursuant to any applicable abandoned property, escheat or
similar law. If any Certificates shall not have been surrendered prior to seven
years after the Effective Time (or immediately prior to such earlier date on
which any payment pursuant to this Article I would otherwise escheat to or
become the property of any Governmental Entity (as hereinafter defined)), the
cash payment in respect of such Certificate shall, to the extent permitted by
applicable law, become the property of the Surviving Corporation, free and clear
of all claims or interests of any person previously entitled thereto.

          (f)  Lost, Stolen or Destroyed Certificates.  If any Certificate shall
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the person claiming such Certificate to be lost, stolen or destroyed
and, if required by Parent or the Paying Agent, the posting by such person of a
bond, in such reasonable amount as Parent or the Paying Agent may direct as
indemnity against any claim that may be made
<PAGE>
 
against them with respect to such Certificate, the Paying Agent will pay in
exchange for such lost, stolen or destroyed Certificate the amount of cash to
which the holders thereof are entitled pursuant to Section 1.6.

          Section 1.8  Further Assurances.  If at any time after the Effective
 Time the Surviving Corporation shall consider or be advised that any deeds,
 bills of sale, assignments or assurances or any other acts or things are
 necessary, desirable or proper (a) to vest, perfect or confirm, of record or
 otherwise, in the Surviving Corporation its right, title or interest in, to or
 under any of the rights, privileges, powers, franchises, properties or assets
 of either of the Constituent Corporations, or (b) otherwise to carry out the
 purposes of this Agreement, the Surviving Corporation and its proper officers
 and directors or their designees shall be authorized to execute and deliver, in
 the name and on behalf of either of the Constituent Corporations, all such
 deeds, bills of sale, assignments and assurances and to do, in the name and on
 behalf of either Constituent Corporation, all such other acts and things as may
 be necessary, desirable or proper to vest, perfect or confirm the Surviving
 Corporation's right, title or interest in, to or under any of the rights,
 privileges, powers, franchises, properties or assets of such Constituent
 Corporation and otherwise to carry out the purposes of this Agreement.

          Section 1.9  Closing.  The closing of the Merger (the "Closing") and
all actions specified in this Agreement to occur at the Closing shall take place
at the offices of Sidley & Austin, One First National Plaza, Chicago, Illinois
60603, at 10:00 a.m., local time, no later than the second business day
following the day on which the last of the conditions set forth in Article VI
shall have been fulfilled or waived (if permissible) or at such other time and
place as Parent and the Company shall agree.

standing under the laws of the jurisdiction of its incorporation and has the
requisite corporate power and authority to carry on its business as now being

standing or to have such power or authority would not, individually or in the
aggregate, have a Material Adverse Effect on the Company. The Company and each
of its Subsidiaries are duly qualified to do business, and are in good standing,
in each jurisdiction where the character of their properties owned or held under
lease or the nature of their activities makes such qualification necessary,
except where the failure to be so qualified would not, individually or in the
<PAGE>
 
aggregate, have a Material Adverse Effect on the Company or materially delay the
consummation of the Merger.

           Section 3.2 Subsidiaries. Section 3.2 of the letter dated the date
hereof and delivered on the date hereof by the Company to Parent, which relates
to this Agreement and is designated therein as the Company Letter (the "Company
Letter") lists each Subsidiary of the Company. All of the outstanding shares of
capital stock of each such Subsidiary that is a corporation have been validly
issued and are fully paid and nonassessable. Except as set forth in Section 3.2
of the Company Letter, all of the outstanding shares of capital stock of each
Subsidiary of the Company are owned by the Company, by another Subsidiary of the
Company or by the Company and another Subsidiary of the Company, free and clear
of any and all mortgages, liens, encumbrances, charges, claims, restrictions,
pledges, security interest or impositions (collectively, "Liens") and free and
clear of all options, rights of first refusal, agreements or limitations on
voting rights of any nature whatsoever. Except as set forth in Section 3.2 of
the Company Letter and except for the capital stock of its Subsidiaries, the
Company does not own, directly or indirectly, any capital stock or other
ownership interest in any corporation, partnership, joint venture, limited
liability company or other entity which is material to the business or financial
position of the Company.

on January 30, 1999:

           (i) 36,360,377 Shares were issued and outstanding, all of which were
validly issued, fully paid and nonassessable and free of preemptive rights;

           (ii)  No shares of Company Preferred Stock were issued and

           (iii) No Shares were held in the treasury of the Company or by

           (v) 400,000 Shares were reserved for issuance in the aggregate

of the date of this Agreement of each outstanding option to purchase shares of
Company Common Stock issued under the Company Stock Option Plan (collectively,
the "Company Stock Options"), including the holder, date of grant, exercise
price and number of shares of Company Common Stock subject thereto and whether
the option is vested and exercisable. Except for the Company Stock Options, the
Company Stock Option Plan, the Company Stock Purchase Plan and the Company
Restricted Stock Plan, there are no options, warrants, calls, rights or
agreements to which the Company or any of its Subsidiaries is a party or by
which any of them is bound obligating the Company or any of its Subsidiaries to
issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of capital stock of the Company or any of its Subsidiaries or obligating
the Company or any of its Subsidiaries to grant, extend or enter into any such
option, warrant, call, right or agreement. Except as set forth in Section 3.3 of
the Company Letter, there are no outstanding contractual obligations of the
Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire
any shares of Company Common Stock or any capital stock of or any equity
interests in any of the Company's Subsidiaries. The Company does not have any
outstanding bonds, debentures, notes or other obligations the holders of which

proceedings on the part of the Company or its Board of Directors are necessary
to authorize and approve this Agreement or to consummate the transactions
contemplated hereby, other than (x) approval and adoption of this Agreement by
the stockholders of the Company and (y) the filing of the Certificate of Merger
as required by the DGCL. This Agreement has been duly executed and delivered by
the Company and (assuming the valid authorization, execution and delivery of

this Agreement on Parent and Merger Sub) constitutes the valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, except as such enforceability may be limited by bankruptcy, insolvency,

or regulation applicable to the Company or any of its Subsidiaries or any of
their respective properties or assets (including any of the Company Merchant
Contracts), other than, in the case of clauses (iii) or (iv), any such
violations, defaults, rights, or Liens that, individually or in the aggregate,
would not have a Material Adverse Effect on the Company, materially impair the
ability of the Company to perform its obligations hereunder or prevent or
materially delay the consummation of any of the transactions contemplated
hereby. No filing or registration with, or authorization, consent or approval

or with respect to the Company or any of its Subsidiaries in connection with the

impair the ability of the Company to perform its obligations hereunder or
prevent or materially delay the consummation of any of the transactions
contemplated hereby.

           Section 3.6 SEC Documents and Other Reports. The Company has filed
all required documents (including proxy statements) with the SEC since June 29,
1997 (as such documents have been amended since the time of their filing and
prior to the date hereof, the "Company SEC Documents"). As of their respective
dates or, if amended, as of the date of the last such amendment, the Company SEC
Documents complied in all material respects with the requirements of the
Securities Act of 1933, as amended (the "Securities Act"), or the Exchange Act,
as the case may be, and, at the respective times they were filed or, if amended,
as of the date of the last such amendment, none of the Company SEC Documents,
including the financial statements of the Company and the notes thereto,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. The
consolidated financial statements (including, in each case, any notes thereto)
of the Company included in the Company SEC Documents complied as to form in all
material respects with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, were prepared in
accordance with United States GAAP (except, in the case of the unaudited
statements, as permitted by Form 10-Q of the SEC) applied on a consistent basis
during the periods involved (except as may be indicated
<PAGE>
 
therein or in the notes thereto) and fairly presented the consolidated financial
position of the Company and its consolidated Subsidiaries as at the respective
dates thereof and the consolidated results of their operations and their
consolidated cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments and to any other
adjustments described therein none of which were or will be material in amount
or effect). Except as disclosed in the Company SEC Documents or as required by
GAAP, the Company has not, since June 29, 1997, made any change in the
accounting practices or policies applied in the preparation of financial
statements.

accrued, absolute, contingent or otherwise required by generally accepted
accounting principles ("GAAP") to be set forth on a consolidated balance sheet
of the Company and its Subsidiaries or in the notes thereto, other than
liabilities or obligations that would not, individually or in the aggregate,

with their terms, of any such claims, liabilities or obligations (in each case

statements in the ordinary course of business consistent with past practice;

          (xvi)  except as required by applicable law or by order of a
Governmental Entity, do any other act which would cause any representation or

<PAGE>
 
become untrue; or

          (xvii) authorize, recommend, propose or announce an intention to do
any of the foregoing, or enter into any contract, agreement, commitment or

          (b) Except as permitted herein, during the period from the date of
this Agreement through the Effective Time, Parent shall not, and shall cause
each of its Subsidiaries not to, consummate or enter into any agreement to
consummate any transaction which would reasonably be expected to delay or impede
the consummation of the Merger or which relates to the merchant acquiring
business and would require filings to be made under the HSR Act; provided,
however, that this Section 4.1(b) shall be inapplicable with respect to the
exercise or enforcement by Parent or any of its Subsidiaries of any of their
current rights (including, without limitation, options to acquire assets or
perform services) or the performance by Parent or any of its Subsidiaries of any
current obligations (including, without limitation, in connection with rights of
third parties to require Parent or any of its Subsidiaries to acquire assets or
perform services).

          Section 4.2 No Solicitation. (a) The Company shall, and shall cause
its Subsidiaries and its and their respective officers, directors, employees,
financial advisors, attorneys and other advisors and representatives
(collectively, "Company Representatives") to immediately cease any discussions
or negotiations with any Person that may be ongoing with respect to any
possibility or consideration of making a Takeover Proposal (as hereinafter
defined). The Company shall not, nor shall it permit any of its Subsidiaries to,
nor shall it authorize or permit any Company Representative to, directly or
indirectly, (i) solicit, initiate or encourage any inquiries or the making or
implementation of any Takeover Proposal, (ii) make or implement or participate
in the making or implementation of any Takeover Proposal, (iii) approve or
recommend (except with respect to a Superior Proposal in respect of which the
Company is entitled to discuss or negotiate in accordance with this Section
4.2), or enter into any agreement with respect to, any Takeover Proposal or (iv)
participate in any discussions or negotiations regarding, or furnish to any
Person any information with respect to the Company or any of its Subsidiaries in
connection with, or take any other action that may
<PAGE>
 
reasonably be expected to lead to any Takeover Proposal; provided, however, that
nothing contained in this Section 4.2(a) shall prohibit the Company or its
directors from complying with Rules 14d-9 and 14e-2 promulgated under the
Exchange Act with regard to a tender or exchange offer; and provided, further,
that prior to the Effective Time, if (A) the Company receives a request for non-
public information that was not solicited in violation of this Section 4.2(a)
from a party who proposes a written bona fide Takeover Proposal and if the Board
of Directors of the Company determines in good faith that the failure to provide
the information requested would be inconsistent with such Board's fiduciary
duties to the Company and its stockholders or otherwise breach or violate
applicable law (based on the advice of outside legal counsel to the Company to
such effect, which advice shall specifically take into account the Stockholder
Agreement and all the terms thereof, including the obligations and agreements
therein of Bank One and First USA with respect to the Shares owned by First USA
and voting for the Merger and against any Takeover Proposal other than the
Merger (the "Legal Advice")), then the Company and the Company Representatives
may, in response to an unsolicited request therefor, and subject to compliance
with Section 4.2(b), furnish information with respect to the Company and its
Subsidiaries to the Person making such Takeover Proposal pursuant to a customary
confidentiality agreement (as determined by the Company's outside legal counsel)
on terms not in the aggregate materially more favorable to such Person than the
terms contained in the Confidentiality Agreement, and (B) (i) a Takeover
Proposal constitutes a Superior Proposal (as hereinafter defined), and (ii) the
Board of Directors of the Company reasonably determines in good faith that the
failure to provide the information requested or to engage in discussions or
negotiations would be inconsistent with such Board's fiduciary duties to the
Company and its stockholders or otherwise breach or violate applicable law
(based on Legal Advice), then to the extent such failure is inconsistent with
such Board's fiduciary duties (determined as aforesaid), the Company and the
Company Representatives may, in response to an unsolicited request therefor, and
subject to compliance
<PAGE>
 
with Section 4.2(b), participate in discussions or negotiations with such
Person. Without limiting the foregoing, it is understood that any violation of
the restrictions set forth in the preceding sentence by any Company
Representative, whether or not such person is purporting to act on behalf of the
Company or any of its Subsidiaries or otherwise, shall be deemed to be a breach
of this Section 4.2(a) by the Company. For purposes of this Agreement, "Takeover
Proposal" means (i) any written proposal or offer for a tender offer,
recapitalization, merger, consolidation or other business combination involving
the Company or any of its Subsidiaries or any proposal or offer to acquire in
any manner, directly or indirectly, an equity interest in, any voting securities
of, or a substantial portion of the assets of the Company or any of its
Subsidiaries, other than the transactions contemplated by this Agreement, the
Stockholder Agreement and the Contribution Agreement or (ii) any other
transaction the consummation of which could reasonably be expected to impede,
interfere with, prevent or materially delay the Merger or which could reasonably
be expected to dilute or adversely affect materially the benefits to Parent of
the transactions contemplated by this Agreement, the Stockholder Agreement and
the Contribution Agreement, and "Superior Proposal" means a bona fide Takeover
Proposal made by a third party on terms which the Board of Directors of the
Company reasonably determines in good faith to be more favorable to the
Company's stockholders than the Merger (based on a written opinion, with only
customary qualifications, from a nationally recognized investment banking firm
serving as financial advisor to the Company (a "Banker Opinion") that the value
of the consideration provided for in such proposal exceeds the Merger
Consideration) and for which financing, to the extent required, is then
committed or which the Board of Directors reasonably determines in good faith
(based on a Banker Opinion) is highly likely to be obtained by such third party.
In making its determination whether a Takeover Proposal constitutes a Superior
Proposal pursuant to the preceding sentence, the Board of Directors shall take
into account whether such Takeover Proposal has a reasonable prospect of being
consummated prior to October 1, 1999. Notwithstanding the foregoing, unless this
Agreement shall have been terminated pursuant to the terms hereof, nothing shall
prevent Parent, in its discretion, from consummating the Merger.
<PAGE>
 
          (b) The Company shall advise Parent and Bank One orally and in writing
of (i) any Takeover Proposal or any inquiry with respect to or which could lead
to any Takeover Proposal received by any officer or director of the Company or,
to the knowledge of the Company, any other Company Representative and (ii) the
identity of the Person making any such Takeover Proposal or inquiry, no later
than 24 hours following receipt of such Takeover Proposal or inquiry. If the
Company intends to furnish any Person with any information with respect to any
Takeover Proposal in accordance with Section 4.2(a), the Company shall advise
Parent and Bank One orally and in writing of such intention not less than 24
hours in advance of providing such information and shall promptly provide to
Parent and Bank One any information concerning the Company, its Subsidiaries,
business, properties or assets furnished to any third party and which has not
previously been provided to Parent and Bank One.

          Section 4.3 Third Party Standstill Agreements. During the period from
 the date of this Agreement through the Effective Time, the Company shall not
 terminate, amend, modify or waive any provision of any standstill agreement to
 which the Company or any of its Subsidiaries is a party (other than, to the
 extent mutually agreed between Parent and the Company, any such agreement
 involving Parent). During such period, the Company agrees to enforce, to the
 fullest extent permitted under applicable law, the provisions of any such
 agreements, including, but not limited to, obtaining injunctions to prevent any
 breaches of such agreements and to enforce specifically the terms and
 provisions thereof in any court of the United States or any state thereof
 having jurisdiction.

                             ADDITIONAL AGREEMENTS

           Section 5.1 Stockholder Meeting. (a) As soon as practicable following
the execution of this Agreement, the Company will duly call, give notice of,
convene and hold a meeting of stockholders (the "Stockholder Meeting") for the
purpose of considering the adoption of this Agreement and the approval of the
Merger and at such meeting call for a vote and cause proxies to be voted in
respect of the adoption of this Agreement and the Company will, through its
Board of Directors, recommend to its stockholders the adoption of this
Agreement, and shall not withdraw or modify such recommendation (unless it has
been previously withdrawn pursuant to the terms of Section 4.2). This Agreement
shall be submitted to the Company's stockholders at the Stockholder Meeting
whether or not the Board of Directors determines at any time that this Agreement
is no longer advisable and recommends that the stockholders reject it.

           (b) As soon as practicable after the execution of this Agreement, the
Company shall prepare and file a preliminary Proxy Statement with the SEC and
shall use its reasonable best efforts to respond to any comments of the SEC or
its staff and to cause the Proxy Statement to be mailed to the Company's
stockholders as promptly as practicable after responding to all such comments to
the satisfaction of the staff. The Company shall notify Parent and Bank One
promptly of the receipt of any comments from the SEC or its staff and of any
request by the SEC or its staff for amendments or supplements to the Proxy
Statement or for additional information and will supply Parent and Bank One with
copies of all correspondence between the Company or any of its representatives,
on the one hand, and the SEC or its staff, on the other hand, with respect to
the Proxy Statement or the Merger. If at any time prior to the Stockholder
Meeting there shall occur any event that should be set forth in an amendment or
supplement to the Proxy Statement, the Company shall promptly prepare and mail
to its stockholders such an amendment or supplement. Parent and its counsel and
Bank One and its counsel shall be given a reasonable opportunity to review and
comment upon the Proxy Statement and any such correspondence prior to its filing
with the SEC or dissemination to the Company's Stockholders. The Company shall
not so file or disseminate any Proxy Statement, or any amendment or supplement
thereto, to
<PAGE>
 
which Parent or Bank One reasonably objects. Parent and Bank One shall cooperate
with the Company in the preparation of the Proxy Statement or any amendment or
supplement thereto.

           Section 5.2 Access to Information. During the period from the date of
this Agreement through the Effective Time and subject to currently existing
contractual and legal restrictions applicable to the Company or any of its
Subsidiaries, the Company shall, and shall cause each of its Subsidiaries to,
afford to the accountants, counsel, financial advisors and other representatives
of Parent reasonable access to, and permit them to make such inspections as they
may reasonably require of, all of their respective properties, books, contracts,
commitments and records and, during such period, the Company shall, and shall
cause each of its Subsidiaries to (i) furnish promptly to Parent a copy of each
report, schedule, registration statement and other document filed by it during
such period pursuant to the requirements of federal or state securities laws,
(ii) furnish promptly to Parent all other information concerning its business,
properties and personnel as Parent may reasonably request and (iii) promptly
make available to Parent all personnel of the Company and its Subsidiaries
knowledgeable about matters relevant to such inspections; provided, however,
that the foregoing shall not require the Company or any of its Subsidiaries to
furnish or otherwise make available to Parent or any of its Subsidiaries
customer-specific data or competitively sensitive information relating to areas
of the company's business in which Parent and/or any of its Subsidiaries
competes against the Company. No investigation pursuant to this Section 5.2
shall affect any representation or warranty in this Agreement of any party
hereto or any condition to the obligations of the parties hereto. All
information obtained by Parent pursuant to this Section 5.2 shall be kept
confidential in accordance with the Letter Agreement, dated September 4, 1997
between Parent and the Company, as confirmed in a letter dated October 22, 1998
from Parent to the Company (collectively, the "Confidentiality Agreement").

           Section 5.3 Costs and Expenses; Termination Fee. (a) Except as
provided in this Section 5.3, all costs and expenses incurred in connection with
this Agreement and the transactions contemplated hereby (including the Merger),
including the fees and disbursements of counsel, financial advisors and
accountants, shall be paid by the party incurring such
<PAGE>
 
costs and expenses, whether or not the Merger is consummated.

           (b) The Company shall pay, or cause to be paid, in same day funds to
Parent $10 million (the "Termination Fee"), under the circumstances and at the
times set forth as follows:

           (i) if Parent terminates this Agreement under Section 7.1(d) the
Company shall pay the Termination Fee upon demand; and

           (ii) if the Company terminates this Agreement under Section 7.1(e),
the Company shall pay the Termination Fee simultaneously with such termination.

           (c) If this Agreement is terminated pursuant to Section 7.1(b)(i) and
 at the time of such termination the condition set forth in Section 6.1(c) shall
 not have been fulfilled, then Parent shall reimburse the Company upon demand
 for all documented out-of-pocket fees and expenses incurred or paid by or on
 behalf of the Company in connection with this Agreement and the transactions
 contemplated hereby, including all fees and expenses of its counsel, financial
 advisor, accountant and other consultants and advisors; provided, however, that
 Parent shall not be obligated to make payments pursuant to this Section 5.3(c)
 in excess of $2 million in the aggregate.

           Section 5.4 Stock Options. (a) Prior to the Effective Time, the Board
of Directors of the Company (or, if appropriate, any committee thereof) shall
adopt appropriate resolutions and take all other actions necessary or
appropriate, if any, to (i) cause each Company Stock Option that is outstanding
as of the date hereof to vest and to be exercisable immediately prior to the
consummation of the Merger, (ii) cause all restrictions applicable to any
restricted stock award heretofore granted under the Company Restricted Stock
Plan or any other similar plan outstanding upon the consummation of the Merger
to lapse immediately prior to the Effective Time and (iii) cause each Company
Stock Option that is outstanding upon the consummation of the Merger to be
exercisable solely for the Merger Consideration for each Share issuable upon
exercise thereof immediately prior to the Effective Time. The Company shall
offer each holder of a Company Stock Option (an "Option Holder"), in exchange
for the cancellation thereof, the right to receive from the Company an amount
<PAGE>
 
equal to (A) the product of (1) the number of shares of Company Common Stock
subject to such Company Stock Option and (2) the excess, if any, of the Merger
Consideration over the exercise price per share for the purchase of the Company
Common Stock subject to such Company Stock Option, minus (B) all applicable
federal, state and local Taxes required to be withheld in respect of such
payment. The amounts payable pursuant to the immediately preceding sentence of
this 5.4 shall be paid as soon as reasonably practicable following the Effective
Time. The surrender of an Option in exchange for the consideration contemplated
by the second sentence of this Section 5.4 shall be deemed a release of any and
all rights the Option Holder had or may have had in respect thereof. The Company
shall take all such steps as may be required to cause the transactions
contemplated by this Section 5.4 and any other dispositions of Company equity
securities (including derivative securities) in connection with this Agreement
by each individual who is a director or officer of the Company to be exempt
under Rule 16b-3 promulgated under the Exchange Act, such steps to be taken in
accordance with the No-Action Letter dated January 12, 1999, issued by the SEC
to Skadden, Arps, Slate, Meagher & Flom LLP.

           (b) The Company shall take all actions necessary to ensure that (i)
the Offering Period (as defined in the Company Stock Purchase Plan) applicable
to the options outstanding under the Company Stock Purchase Plan (each, a
"Purchase Plan Option") is shortened in accordance with Section 16 of the
Company Stock Purchase Plan so as to have an Exercise Date (as defined in the
Company Stock Purchase Plan) that occurs before the Effective Time; (ii) no new
Offering Period, other than the Offering Period scheduled to commence on April
1, 1999, shall commence on or after the date hereof, and (iii) no holder of a
Purchase Plan Option is permitted to increase his or her rate of payroll
deduction under the Company Stock Purchase Plan from and after the date hereof.

           (c) The Company shall take all actions necessary to provide that,
prior to the Effective Time, (i) the Company Stock Option Plan, the Company
Stock Purchase Plan and any similar plan or agreement of the Company shall be
terminated, (ii) any rights under any other plan, program, agreement or
arrangement to the issuance or grant of any other interest in
<PAGE>
 
respect of the capital stock of the Company or any of its Subsidiaries shall be
terminated, and (iii) no Option Holder will have any right to receive any shares
of capital stock of the Company or, if applicable, the Surviving Corporation,
upon exercise of any Company Stock Option.

           (d) The Company represents and warrants that it has the power and
authority under the terms of the Company Stock Purchase Plan and each of the
Company Stock Option Plan and the Company Restricted Stock Plan to comply with
subsections (a), (b) and (c) hereof without the consent of any Option Holder or
any other person.

           Section 5.5 Reasonable Best Efforts. (a) Upon the terms and subject
to the conditions set forth in this Agreement, each of the parties agrees to use
its reasonable best efforts to take, or cause to be taken, all actions, and to
do, or cause to be done, and to assist and cooperate with the other parties in
doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger and the other
transactions contemplated by this Agreement, including: (i) the obtaining of all
necessary actions or non-actions, waivers, consents and approvals from all
Governmental Entities and Card Associations and the making of all necessary
registrations and filings (including filings under the HSR Act, the Change in
Bank Control Act and the Utah Statute and other filings with Governmental
Entities) and the taking of all reasonable steps as may be necessary to obtain
an approval or waiver from, or to avoid an action or proceeding by, any
Governmental Entity (including furnishing all information required under the HSR
Act, the Change in Bank Control Act and the Utah Statute and actions in
connection with State Takeover Approvals); (ii) the obtaining of all necessary
consents, approvals or waivers from third parties; (iii) the defending of any
lawsuits or other legal proceedings, whether judicial or administrative,
challenging this Agreement or the consummation of the transactions contemplated
hereby and thereby, including seeking to have any stay or temporary restraining
order entered by any court or other Governmental Entity vacated or reversed; and
(iv) the execution and delivery of any additional instruments necessary to
consummate the transactions contemplated by this Agreement. Each party will
promptly consult with the other with respect to, provide any necessary
information with respect to and provide the other (or its counsel) and Bank One
(or
<PAGE>
 
its counsel) copies of, all filings made by such party with any Governmental
Entity in connection with this Agreement and the transactions contemplated
hereby. In addition, if at any time prior to the Effective Time any event or
circumstance relating to any of the Company, Parent or Merger Sub or any of
their respective Subsidiaries, or any of their respective officers or directors,
should be discovered by the Company, Parent or Merger Sub, as the case may be,
and which should be set forth in an amendment or supplement to the Proxy
Statement or the Schedule 13e-3, the discovering party will promptly inform the
other party of such event or circumstance. No party to this Agreement shall
consent to any voluntary delay of the consummation of the Merger at the behest
of any Governmental Entity without the consent of the other parties to this
Agreement, which consent shall not be unreasonably withheld.

           (b) Each party shall use all reasonable best efforts to not take any
action, or enter into any transaction, which would cause any of its
representations or warranties contained in this Agreement to be untrue or result
in a breach of any covenant made by it in this Agreement.

           (c) Notwithstanding anything to the contrary contained in this
Agreement, in connection with any filing or submission required or action to be
taken by either Parent or the Company to effect the Merger and to consummate the
other transactions contemplated hereby, the Company shall not, without Parent's
prior written consent, commit to any divestiture transaction other than with
respect to the Excluded Assets (as defined in the Contribution Agreement), and
neither Parent nor any of its affiliates shall be required to divest or hold
separate or otherwise take or commit to take any action that limits its freedom
of action with respect to, or its ability to retain, the Company or any of the
businesses, product lines or assets of Parent or any of its Subsidiaries or that
would have a Material Adverse Effect on Parent.

           Section 5.6 Public Announcements. Parent and the Company will not
issue any press release with respect to the transactions
<PAGE>
 
contemplated by this Agreement or otherwise issue any written public statements
with respect to such transactions without prior consultation with the other
party and Bank One, except as may be required by applicable law or by
obligations pursuant to any listing agreement with any national securities
exchange.

           Section 5.7 State Takeover Laws. If any "fair price," "business
combination" or "control share acquisition" statute or other similar statute or
regulation is or may become applicable to the transactions contemplated hereby,
in the Stockholder Agreement or in the Contribution Agreement such that, without
further approval or action by Parent, the Company or their respective Boards of
Directors, such transactions cannot be consummated in accordance with the terms
hereof and thereof and such statute or regulations, then Parent and the Company
and their respective Boards of Directors shall use their reasonable efforts to
grant such approvals and take such actions as are necessary so that the
transactions contemplated hereby and thereby may be consummated as promptly as
practicable on the terms contemplated hereby and thereby and otherwise act to
minimize the effects of any such statute or regulation on the transactions
contemplated hereby and thereby.

           Section 5.8 Indemnification; Directors and Officers Insurance. (a)
From and after the Effective Time, Parent shall cause the Surviving Corporation
to indemnify and hold harmless all past and present officers and directors of
the Company and of its Subsidiaries (each an "Indemnified Party") to the same
extent and in the same manner such persons are indemnified as of the date of
this Agreement by the Company pursuant to the DGCL, the Company Charter or the
Company's By-laws for acts or omissions occurring at or prior to the Effective
Time. Parent also agrees to advance expenses as incurred to the fullest extent
permitted under the DGCL upon receipt from the applicable Indemnified Party to
whom expenses are to be advanced of an undertaking to repay such advances if it
is ultimately determined that such person is not entitled to indemnification
pursuant to this Section 5.8(a).

           (b) Parent shall cause the Surviving Corporation to provide, for an
aggregate period of not less than six years from the Effective Time, the
Company's current directors and officers an insurance and
<PAGE>
 
indemnification policy that provides coverage for events occurring prior to the
Effective Time (the "D&O Insurance") that is substantially similar to the
Company's existing policy or, if substantially equivalent insurance coverage is
unavailable, the best available coverage; provided, however, that the Surviving
Corporation shall not be required to pay an annual premium for the D&O Insurance
in excess of 150% of the last annual premium paid prior to the date hereof but
in such case shall purchase as much coverage as possible for such amount.

           (c) The provisions of this Section 5.8(i) are intended to be for the
benefit of, and will be enforceable by, each Indemnified Party, his or her heirs
and his or her representatives and (ii) are in addition to, and not in
substitution for, any other rights to indemnification or contribution that any
such person may have by contract or otherwise.

           Section 5.9 Notification of Certain Matters. Parent shall use its
reasonable best efforts to give prompt notice to the Company and Bank One, and
the Company shall use its reasonable best efforts to give prompt notice to
Parent and Bank One, of: (i) the occurrence, or non-occurrence, of any event the
occurrence, or non-occurrence, of which it is aware and which would be
reasonably likely to cause (x) any representation or warranty contained in this
Agreement and made by it to be untrue or inaccurate in any material respect or
(y) any covenant, condition or agreement contained in this Agreement and made by
it not to be complied with or satisfied in all material respects, (ii) any
failure of Parent or the Company, as the case may be, to comply in a timely
manner with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder or (iii) any change or event which has had a
Material Adverse Effect on the Company; provided, however, that the delivery of
any notice pursuant to this Section 5.9 shall not limit or otherwise affect the
remedies available hereunder to the party receiving such notice.
<PAGE>
 
           Section 5.10 Certain Litigation. The Company agrees that it shall not
settle any litigation commenced after the date hereof against the Company or any
of its directors by any stockholder of the Company relating to the Merger, this
Agreement or the Stockholder Agreement without the prior written consent of
Parent, which consent may not be unreasonably withheld. In addition, the Company
shall not voluntarily cooperate with any third party that may hereafter seek to
restrain or prohibit or otherwise oppose the Merger and shall cooperate with
Parent and Merger Sub to resist any such effort to restrain or prohibit or
otherwise oppose the Merger.

           Section 5.11 Revolving Credit Agreement. The Company agrees to use
reasonable efforts to obtain a waiver of the restrictions on dividends or other
distributions by the Company under its existing revolving credit agreement and
the consent to the transfer of such revolving credit agreement to the Alliance.

contemplated by this Agreement, the Stockholder Agreement or the Contribution
Agreement.

Merger Sub. The obligations of Parent and Merger Sub to effect the Merger shall
be subject to fulfillment of the following additional conditions, any of which,

reasonable opinion of both counsel to Parent and to the Company, are unlikely to
result in an adverse judgement.

One nor First USA shall have terminated the Stockholder Agreement or the
Contribution Agreement (whether or not in accordance with the terms thereof) and
neither Bank One nor First USA shall be in material breach thereof or shall have

                                ARTICLE VII

                     TERMINATION, AMENDMENT AND WAIVER

           Section 7.1 Termination. This Agreement may be terminated at any time
 prior to the Effective Time, whether before or after approval of this Agreement
 by the stockholders of the Company:

           (a)  by mutual written consent of Parent and the Company;

           (b)  by either Parent or the Company:

                (i)  if the Merger shall not have been consummated prior to
           October 1, 1999; provided, however, that the right to terminate this
           Agreement pursuant to this Section 7.1(b)(i) shall not be available
           to any party whose failure to perform any of its obligations under
           this Agreement results in the failure of any such condition or if the
           failure of such condition results from facts or circumstances that
           constitute a breach of any representation or warranty under this
           Agreement by such party; or

                (ii) if any Governmental Entity shall have issued an order,
           decree or ruling or taken any other action permanently enjoining,
           restraining or otherwise prohibiting the Merger or the other
           transactions contemplated by this Agreement, the Stockholder
           Agreement or the Contribution Agreement and such order, decree or
           ruling or other action shall have become final and nonappealable;

           (c)  by Parent or the Company in the event of a breach by the other
      (or Merger Sub, in the case of Parent) of any representation, warranty,
      covenant or other agreement contained in this Agreement which (i) would
      reasonably be expected to give rise to the failure of a condition set
      forth in Sections 6.2 (a) or (b) or 6.3 (a) or (b), as
<PAGE>
 
      the case may be, and (ii) cannot be or has not been cured within
      30 days after the giving of written notice of such breach to the
      Company;

           (d)  by Parent if (i) the Board of Directors of the Company or any
      committee thereof shall have withdrawn or modified in a manner adverse to
      Parent its approval or recommendation of the Merger or this Agreement, or
      approved or recommended any Takeover Proposal (whether or not in
      compliance with Section 4.2) or (ii) the Board of Directors of the Company
      or any committee thereof shall have resolved to take any of the foregoing
      actions; or

           (e)  by the Company prior to receipt of the Company Stockholder
      Approval if (i) a Takeover Proposal constitutes a Superior Proposal, and
      (ii) the Board of Directors of the Company reasonably determines in good
      faith that the failure to terminate this Agreement and accept such
      Superior Proposal would be inconsistent with such Board's fiduciary duties
      to the Company and its stockholders or otherwise breach or violate
      applicable law (based on Legal Advice); provided, however, that this
      Agreement shall not terminate pursuant to this Section 7.1(e) unless (i)
      the Company has complied with all provisions of Section 4.2, including the
      notice provisions therein, (ii) simultaneously with such termination the
      Company has complied with the requirements of Section 5.3(b) relating to
      the payment (including the timing of any payment) of the Termination Fee
      to the extent required by Section 5.3(b) and (iii) simultaneously with
      such termination the Company enters into a definitive acquisition, merger
      or similar agreement to effect such Superior Proposal; and provided,
      further, that the Company may not terminate this Agreement pursuant to
      this Section 7.1(e) unless and until 120 hours have elapsed following
      delivery to Parent and Bank One of a written notice of such determination
      by the Board of Directors of the Company and during such 120 hours Parent
      has not informed the Company that it is willing to substantially match the
      terms and conditions of such Superior Proposal.

           The right of any party hereto to terminate this Agreement pursuant to
 this Section 7.1 shall remain operative and in full force and effect regardless
 of any investigation made by or on behalf of any 
<PAGE>
 
 party hereto, any person controlling any such party or any of their respective
 officers or directors, after the execution of this Agreement.

           Section 7.2 Effect of Termination. In the event of termination of
 this Agreement by either Parent or the Company, as provided in Section 7.1,
 this Agreement shall forthwith become void and there shall be no liability
 hereunder on the part of the Company, Parent, Merger Sub or their respective
 officers or directors (except for Section 2.5, 2.7, 3.23, the last sentence of
 Section 5.2, Section 5.3, this Section 7.2 and Article VIII, all of which shall
 survive the termination); provided, however, that nothing contained in this
 Section 7.2 shall relieve any party hereto from any liability for any willful
 breach of a representation or warranty contained in this Agreement or the
 material breach of any covenant contained in this Agreement.

           Section 7.3 Amendment. This Agreement may be amended by the parties
 hereto, at any time before or after Company Stockholder Approval (if required
 by law); provided, that (i) if the Company Stockholder Approval shall have been
 obtained, thereafter no amendment shall be made which by law requires further
 approval by such stockholders without such further approval and (ii) no
 amendment of this Agreement shall be made effective without the prior written
 consent of Bank One which consent shall not be unreasonably withheld. This
 Agreement may not be amended except by an instrument in writing signed on
 behalf of each of the parties hereto.

           Section 7.4 Extension; Waiver. At any time prior to the Effective
 Time and subject to in clause (ii) of Section 7.3, the parties hereto may to
 the extent legally allowed (i) extend the time for the performance of any of
 the obligations or other acts of the other parties hereto, (ii) waive any
 inaccuracies in the representations and warranties contained herein or in any
 document delivered pursuant hereto and (iii) waive compliance with any of the
 agreements or conditions contained herein. Any agreement on the part of a party
 hereto to any such extension or waiver shall be valid only if set forth in an
 instrument in writing signed on behalf of such party. The failure of any party
 to this Agreement to assert any of its rights under this Agreement or otherwise
 shall not constitute a waiver of those rights.

           Section 8.5 Entire Agreement; No Third-Party Beneficiaries. This
 Agreement, except as provided in the last sentence of Section 5.2, constitutes
 the entire agreement, and supersedes all prior agreements and understandings,
 both written and oral, among the parties with respect to the subject matter
 hereof. This Agreement, except for the provisions of Sections 1.2 and 5.8 and
 except as expressly set forth in Sections 1.5, 1.7(a), 2.4, 4.2(b), 5.1, 5.5,

           Section 8.6 Governing Law. This Agreement shall be governed by, and
 construed in accordance with, the laws of the State of Delaware, regardless of

 of laws thereof. In addition, each of the parties hereto (i) consents to submit
 itself to the personal jurisdiction of any Federal or state court located in
 the State of Delaware in the event any dispute arises out of this Agreement or
 any of the transactions contemplated by this Agreement, (ii) agrees that it
 will not attempt to deny or defeat such personal jurisdiction by motion or
 other request for

 will not bring any action relating to this Agreement or any of the transactions
 contemplated by this Agreement in any court other than a Federal or state court

           Section 8.7 Assignment. Subject to Section 1.2, neither this
 Agreement nor any of the rights, interests or obligations hereunder shall be
 assigned by any of the parties hereto (whether by operation of law or
 otherwise) without the prior written consent of the other parties. This
 Agreement shall be binding upon, inure to the benefit of, and be enforceable
 by, the parties and their respective successors and permitted assigns.

           Section 8.8 Severability. If any term or other provision of this
 Agreement is invalid, illegal or incapable of being enforced by any rule of
 law, or public policy, all other terms, conditions and provisions of this
 Agreement shall nevertheless remain in full force and effect so long as the
 economic and legal substance of the transactions contemplated hereby are not
 affected in any manner materially adverse to any party. Upon such determination
 that any term or other provision is invalid, illegal or incapable of being
 enforced, the parties shall negotiate in good faith to modify this Agreement so
 as to effect the original intent of the parties as closely as possible in a
 mutually acceptable manner in order that the transactions contemplated by this
 Agreement may be consummated as originally contemplated to the fullest extent
 possible.

           Section 8.9 Enforcement of this Agreement. The parties hereto agree
 that irreparable damage would occur in the event that any of the provisions of
 this Agreement were not performed in accordance with their specific wording or
 were otherwise breached. It is accordingly agreed that the parties hereto shall
 be entitled to an injunction or injunctions to prevent breaches of this
 Agreement and to enforce specifically the terms and provisions hereof, such
 remedy being in addition to any other remedy to which any party is entitled at
 law or in equity. Each party hereto waives any right to a trial by jury in
 connection with any such action, suit or proceeding.

           IN WITNESS WHEREOF, Parent, Merger Sub and the Company have caused
 this Agreement to be signed by their respective officers thereunto duly
 authorized all as of the date first written above.

          WHEREAS, as an inducement and a condition to entering into the Merger
Agreement, FDC and Merger Sub have required that each of Bank One and First USA
agree, and each of Bank One and First USA has agreed, to enter into this
Agreement.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
promises, representations, warranties, covenants and agreements contained
herein, the parties hereby agree as follows:

          1.   Agreement to Vote: Restriction on Transfer.  Proxies and
Non-Interference.

               (a)  First USA hereby agrees that during the period commencing on
the date hereof and continuing until the termination of this Agreement in
accordance with its terms, at any meeting of the holders of the Company Common
Stock, however called, or in connection with any written consent of the holders
of the Company Common Stock, First USA shall vote (or cause to be voted) the
First USA Shares, (i) in favor of adoption of the Merger Agreement and the
approval of the Merger, all other
<PAGE>
 
transactions contemplated thereby, and any actions required in furtherance
thereof and hereof; (ii) against any action or agreement that is intended, or
could reasonably be expected, to impede, interfere with, or prevent the Merger
or result in a breach in any respect of any covenant, representation or warranty
or any other obligation or agreement of the Company or any of its subsidiaries
under the Merger Agreement or this Agreement; and (iii) except as specifically
requested in writing in advance by FDC or as permitted pursuant to the terms of
the Merger Agreement, against the following actions (other than the Merger and
the transactions contemplated by or required to implement the Merger Agreement,
this Agreement and the Contribution Agreement): (A) any extraordinary corporate
transaction, such as a merger, consolidation or other business combination
involving the Company or any of its subsidiaries or affiliates; (B) a sale,
lease, transfer or disposition by the Company or any of its subsidiaries of any
assets outside the ordinary course of business or any assets which in the
aggregate are material to the Company and its subsidiaries taken as a whole, or
a reorganization, recapitalization, dissolution or liquidation of the Company or
any of its subsidiaries or affiliates; (C)(1) any change in the management of
the Company or any of its subsidiaries or in a majority of the persons who
constitute the board of directors of the Company or any of its subsidiaries; (2)
any change in the present capitalization of the Company or any of its
subsidiaries or any amendment of the Company's charter or by-laws or the charter
or by-laws of any of its subsidiaries; (3) any other material change in the
Company's or any of its subsidiaries' corporate structure or business; or (4)
any other action that, in the case of each of the matters referred to in clauses
(C)(1), (2) or (3), is intended, or could reasonably be expected, to impede,
interfere with, delay, postpone or materially adversely affect the Merger or the
transactions contemplated by this Agreement, the Contribution Agreement and the
Merger Agreement. Neither Bank One nor First USA shall enter into any agreement
or understanding with any Person (as defined herein) the effect of which would
be inconsistent with or violative of the provisions and agreements contained in
this Agreement.

               (b)  First USA shall not, directly or indirectly: (i) tender the
First USA Shares in any tender offer for the Company Common Stock; (ii)
<PAGE>
 
except as contemplated by this Agreement, the Contribution Agreement or the
Merger Agreement, otherwise offer for sale, sell, transfer, tender, pledge,
encumber, assign or otherwise dispose of, or enter into any contract, option or
other arrangement or understanding with respect to or consent to the offer for
sale, transfer, tender, pledge, encumbrance, assignment or other disposition of,
any or all of the First USA Shares or any interest therein; (iii) grant any
proxies or powers of attorney, deposit any First USA Shares into a voting trust
or enter into a voting agreement with respect to any First USA Shares; or (iv)
take any action that would make any representation or warranty of First USA
contained herein that is qualified by materiality untrue or incorrect in any
respect or any representation or warranty of First USA contained herein that is
not so qualified untrue or incorrect in any material respect or have the effect
of preventing or disabling First USA from performing First USA's obligations
under this Agreement.

               (c)  So long as this Agreement remains in effect, each instrument
or certificate evidencing or representing First USA Shares shall bear a legend
substantially to the following effect:

          "The shares of Common Stock represented by this certificate are
subject to the transfer and other restrictions stated in a Stockholder Agreement
dated as of March 22, 1999, a copy of which is on file at the office of the
Assistant Secretary of BANK ONE CORPORATION."

               (d)  First USA agrees with, and covenants to, FDC that First USA
shall not request that the Company register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing any of the
First USA Shares, unless such transfer is made in compliance with this
Agreement.

          2.   Waiver of Appraisal and Dissenter's Rights. First USA hereby
irrevocably waives any rights of appraisal or rights to dissent from the Merger
that it may have.

          3.   Schedule 13e-3. FDC, Holdco, Merger Sub, Bank One and First USA
shall, in accordance with the rules and regulations of the SEC, file
<PAGE>
 
with the SEC a Rule 13e-3 Transaction Statement (such Rule 13e-3 Transaction
Statement, as amended from time to time, the "Rule 13e-3 Transaction
Statement"), with respect to the Merger Agreement and the Contribution
Agreement, and such parties shall cause to be disseminated the information
contained therein to holders of the shares of the Company Common Stock as and to
the extent required by the applicable rules and regulations of the SEC. Each of
the parties hereto agrees promptly to correct any information provided by it for
use in the Rule 13e-3 Transaction Statement if and to the extent that such
information shall have become false or misleading in any material respect, and
such parties further agree to take all steps necessary to cause the Rule 13e-3
Transaction Statement as so corrected to be filed with the SEC and the
information contained in such corrected filing to be disseminated to holders of
shares of the Company Common Stock, in each case as and to the extent required
by the applicable rules and regulations of the SEC. FDC and its counsel shall be
given reasonable opportunity to review and comment on the Rule 13e-3 Transaction
Statement prior to its filing with the SEC or dissemination to the stockholders
of the Company. Bank One and First USA agree to provide FDC and its counsel any
comments Bank One, First USA or their counsel may receive from the SEC or its
staff with respect to the Rule 13e-3 Transaction Statement promptly after the
receipt of such comments and to cooperate with FDC and its counsel in responding
to any such comments. The parties hereto jointly agree to cause the Rule 13e-3
Transaction Statement to comply as to form in all material respects with the
requirements of the Exchange Act and to allow the Company to rely upon such
agreement to do so.

          4.   No Solicitation. (a) Other than with respect to the Excluded
Assets, Bank One and its affiliates shall immediately cease existing discussions
or negotiations, if any, with any parties conducted heretofore with respect to
any acquisition of all or any material portion of the assets of, or any equity
interest in, the Company or any of its subsidiaries or any business combination
with the Company or any of its subsidiaries.

               (b)  Bank One and First USA shall not, nor shall they authorize
or permit any of their affiliates or any director, officer, employee, financial
advisor, attorney or other advisor or representative of any of the foregoing to,
directly or indirectly: (i) solicit, initiate or encourage any inquiries or the
making or implementation of any Takeover Proposal; (ii) make or implement or
participate in the making or implementation of any Takeover Proposal; (other
than an agreement
<PAGE>
 
conditioned upon the concurrent exercise by the Company, provided that
concurrently with the effectiveness of such agreement, the Company exercises the
termination right set forth in Section 7.1(e) of the Merger Assignment) (iii)
enter into any agreement with respect to or approve or recommend any Takeover
Proposal; or (iv) participate in any discussions or negotiations regarding, or
furnish to any Person any information with respect to the Company or any of its
Subsidiaries in connection with, or take any other action that may reasonably be
expected to lead to any Takeover Proposal. Notwithstanding the foregoing,
nothing in this Section 4(b) shall prohibit any affiliate of Bank One or First
USA (i) from providing shareholder or proxy services in the ordinary course of
business of such affiliate or (ii) to the extent such affiliate is acting in a
fiduciary capacity, from taking actions directed by one or more of the
beneficiaries or other legal representatives involved in the fiduciary
relationship or as is otherwise required by reason of the fiduciary
relationship. Any action taken by the Company or any member of the Board of
Directors of the Company in accordance with Section 4.2 of the Merger Agreement
shall be deemed not to violate this Section 4.

               (c)  If at any time Bank One or any of its affiliates (other than
the Company and its Subsidiaries) is approached (without any joint or related
approach to the Company or any of its Subsidiaries) by any Person concerning its
participation in a transaction involving any of the assets, businesses or
securities of the Company or any subsidiary thereof (other than with respect to
the Excluded Assets), Bank One will promptly inform FDC of the nature of such
contact and the parties thereto and provide a copy of any such written proposal
and a summary of any oral proposal (including the material terms and conditions
of such proposal) to FDC immediately after receipt thereof. Notwithstanding the
foregoing, nothing in this Section 4(c) shall require any affiliate of Bank One
to provide any notification referred to in the preceding sentence if (i) such
affiliate's participation in such transaction is limited to the provision of
shareholder or proxy services in the ordinary course of business of such
affiliate or (ii) if such affiliate is acting in a fiduciary capacity and such
participation in such transaction is directed by one or more of the
beneficiaries or other legal representatives involved in the fiduciary
relationship or as is otherwise required by reason of the fiduciary

relationship.

<PAGE>
 
          7.   Further Assurances.  From time to time, at FDC's request and
without further consideration, First USA agrees to execute and deliver such
additional documents and take such further lawful action as may be necessary or

it being understood and agreed that First USA shall not be required hereunder to
make any payment (other than customary administrative and processing fees and
reasonable legal expenses), commence litigation or agree to any material
agreements in connection with the foregoing.

          8.   Actions Taken Prior to Consummation of the Merger. (a) Each of
the parties hereto shall take, or cause to be taken, the actions when and as
contemplated by Section 1.1 of the Merger Agreement to be taken by such party;
provided, however that the obligation of First USA to contribute shares of
Company Common Stock owned by it to Holdco shall be subject to the receipt by
First USA of a written opinion of Wachtell, Lipton, Rosen & Katz to the effect
that such contribution and the receipt of ownership interests in Holdco by First
USA shall constitute a transaction qualifying under Section 351 of the Code. The
stockholder agreement relating to the governance of Holdco and the Company
described therein will be in the form attached hereto as Exhibit B. The total
number of shares of common stock to be issued to FDC and First USA in exchange
for their respective contributions to Holdco as contemplated by such Section 1.1
will be in an amount to be agreed upon between First USA and FDC and will be
allocated in the following percentages: (A) to First USA, the percentage (the
"First USA Percentage") obtained by dividing (i) the total number of shares of
Company Common Stock which are contributed by First USA to Holdco in accordance
with Section 1.1 of the Merger Agreement and Section 8 of this Agreement by (ii)
the total number of shares of Company Common Stock outstanding immediately prior
to the Effective Time; and (B) to FDC, the percentage obtained by subtracting
the First USA percentage from 100%. The parties hereto agree to cause Merger Sub
to cause all shares of the Company Common Stock owned by it to be voted in
approval of the Merger.
<PAGE>
 
               (b)  Bank One, as lender under that certain Credit Agreement,
dated February 18, 1999, between Bank One and the Company, hereby grants all
consents required to be obtained by the Company pursuant to such Credit
Agreement in connection with the transactions contemplated by this Agreement,
the Merger Agreement and the Contribution Agreement.

          9.   Actions Taken After Consummation of the Merger.

               (a)  Each of the parties hereto will take all steps reasonably
necessary to cause the consummation of the transactions contemplated by the
Contribution Agreement.

               (b)  Each of the parties hereto agree to cause the Surviving
Corporation to comply with the covenants set forth in Section 5.8 of the
Merger Agreement.

               (c)  FDC, Bank One and First USA shall take actions necessary to
cause the Board of Directors of the Surviving Corporation, immediately after the
Effective Time and until the closing of the transactions contemplated by the
Contribution Agreement occurs, to consist of nine members, five of whom will be
designated by Bank One and four of whom will be designated by FDC. After the
Closing ( as defined in the Contribution Agreement) Bank One and First USA shall
take actions necessary to cause the Board of Directors of the Surviving
Corporation to consist of four members, two of whom will be designated by Bank
One and two of whom will be designated by FDC.

               (d)  Following any payment by the Surviving Corporation in
respect of Dissenting Shares pursuant to Section 262 of the DGCL (excluding any
Dissenting Shares held by stockholders who shall have failed to perfect or who
effectively shall have withdrawn or lost their rights to appraisal of such
Shares under Section 262 of the DGCL), FDC shall pay to the Surviving
Corporation, as a capital contribution (but without the issuance of any
additional shares of capital stock), an amount, in respect of each such
Dissenting Share, equal to the amount paid by the Surviving Corporation in
respect of such Dissenting Share; provided, however, that at such time as the
aggregate amount paid to the Surviving Corporation pursuant to this sentence is
equal to the sum of (i) the product obtained by multiplying the number of
Dissenting Shares in respect of which payment
<PAGE>
 
is made multiplied by the Merger Consideration and (ii) $2 million, then any
payments thereafter made by FDC pursuant to this sentence shall be limited to an
amount per Share equal to the Merger Consideration. Following any payment by the
Surviving Corporation in respect of Dissenting Shares that are held by
stockholders who shall have failed to perfect or who effectively shall have
withdrawn or lost their rights to appraisal of such Shares under Section 262 of
the DGCL but as to which Shares a contribution of cash to Holdco by Parent was
not made pursuant to Section 1.1 of the Merger Agreement, FDC shall pay to the
Surviving Corporation, as a capital contribution (but without the issuance of
any additional shares of capital stock), an amount, in respect of each such
Share, equal to the Merger Consideration.

               (e)  The parties acknowledge and agree that the Surviving
Corporation shall bear the financial responsibility for amounts required to be
paid in respect of the Company Stock Options pursuant to Section 5.4 of the
Merger Agreement.

          10.  Termination.  Except as otherwise provided herein, the covenants
and agreements contained herein shall terminate and have no further force or
effect upon the earliest of (i) the written consent of the parties hereto, (ii)
termination of the Merger Agreement in accordance with its terms (including,
without limitation, termination of the Merger Agreement by the Company pursuant
to Section 7.1(e) of the Merger Agreement), (iii) failure to receive the opinion
required under Section 8 hereof, (iv) the consummation of the transactions
contemplated by the Contribution Agreement, and (v) the termination of the
Contribution Agreement in accordance with its terms. No termination of this
Agreement shall relieve any party hereto from any liability for any breach of
this Agreement.

          11.  Miscellaneous.

          partnership, corporation, limited liability company, joint venture,
          trust, business trust, governmental agency, cooperative, association,

          may be (either alone or through or together with any other
          subsidiary), owns, directly or indirectly, 50% or more of the capital
          stock the holders of which are generally entitled to vote for the
          election of the board of directors or other governing body of such
          corporation or other legal entity.

               (b)   Entire Agreement. This Agreement, the Contribution

obligations under this Agreement of the transferor.

               (d)  Assignment.  This Agreement shall not be assigned
by operation of law or otherwise without the prior written consent of the other
parties, provided that FDC may assign, in its sole discretion, its rights and

assignee does not perform such obligations.

               (e)  Amendments, Waivers, Etc. This Agreement may not be amended,
changed, supplemented, waived or otherwise modified or terminated, except upon
the execution and delivery of a written agreement executed by the relevant

               (g)  Severability.  Whenever possible, each provision or portion
of any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such

               (h)  Specific Performance.  Each of the parties hereto recognizes

shall be entitled to the

remedy of specific performance of such covenants and agreements and injunctive

thereof by any party shall not preclude the simultaneous or later exercise of
any other such right, power or remedy by such party.

               (j)  No Waiver.  The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

               (k)  No Third Party Beneficiaries.  This Agreement, except as
expressly set forth in Section 3 with respect to the Company, is not intended to
be for the benefit of, and shall not be enforceable by, any Person who is not a
party hereto.

               (l)  Governing Law.  This Agreement shall be governed and
construed in accordance with the laws of the State of Delaware, without giving
effect to the principles of conflicts and laws thereof.

are inserted for convenience of reference only and are not intended to be part
of or to affect the meaning or interpretation of this Agreement.

taken together, shall constitute one and the same Agreement.

               (o)  Expenses.  All costs and expenses incurred in connection
with the transactions contemplated by this Agreement shall be for the account of

           WHEREAS, following the Merger, FDC and Bank One desire to cause the

           WHEREAS, in recognition of the additional capabilities that the

          3.3.  CONTRIBUTION OF SPECIFIED ASSETS AND LIABILITIES. Upon the terms
and subject to the conditions of this Agreement, on the Closing Date, FDC and

Liabilities to be transferred to the Alliance as set forth in Article IV and
shall cause the Alliance to assume all such Assumed Liabilities.

          3.4.  ALPHA DELIVERIES. Upon the terms and subject to the conditions
of this Agreement, on the Closing Date, Bank One and FDC, respectively, shall
cause Alpha to deliver to the Alliance all of the following:

          (a)   Certified copies of resolutions of the stockholders and the
     Board of Directors of Alpha authorizing the transactions contemplated
     hereby;

          (b)   An instrument of assignment and assumption in form and substance
     reasonably satisfactory to Bank One and FDC (the "Instrument of Assignment
     and Assumption");

          (c)   Certificates of title or origin (or like documents) with respect
     to any of the Contributed Assets for which a certificate of title or origin
     is required in order to transfer title;

          (d)   Any consents, waivers or approvals obtained by Alpha with
     respect to the Contributed Assets or the consummation of the transactions
     contemplated by this Agreement; and

          (e)   Such other bills of sale, assignments and other instruments of
     transfer or conveyance as either Bank One or FDC may reasonably request or
     as may otherwise be necessary to evidence and effect the assignment,
     transfer, conveyance and delivery of the Contributed
<PAGE>
 
     Assets by Alpha to the Alliance.

          3.5.  ALLIANCE DELIVERIES. Upon the terms and subject to the
conditions of this Agreement, on the Closing Date, Bank One and FDC,
respectively, shall cause the Alliance to deliver to Alpha all of the following:

          (a)   The Instrument of Assignment and Assumption;

          (b)   Such other instruments as either Bank One or FDC may reasonably
      request or as may be otherwise necessary to evidence or effect the
      assumption by the Alliance of the Assumed Liabilities

In addition to the foregoing, on the Closing Date, Alpha will receive a
Membership Interest (as such term is defined in the Operating Agreement) in the
Alliance as described in Section 4.2 of the Operating Agreement. Bank One and
FDC agree that Alpha will be acquiring its Membership Interest for its own
account for investment and with no present intention of distributing or
reselling such Membership Interest or any part thereof.

Alpha will be fully informed as to the applicable limitations upon any
distribution or resale of the Membership Interest, which will not be registered
pursuant to the Securities Act. Bank One and FDC will cause Alpha to agree not
to distribute or resell all or any portion of the Membership Interest if such
distribution or resale would constitute a violation of the Securities Act by
either Alpha or the Alliance.

          3.6.  OTHER DELIVERIES. Upon the terms and subject to the conditions
of this Agreement, on the Closing Date, Bank One and FDC shall cause their
respective Affiliates to deliver to the other party such additional documents
and instruments, including certified copies of corporate charters or comparable
documents, by-laws, resolutions or other items, as either party may reasonably
request.

          3.7.  CONSENTS TO ASSIGNMENT. Anything in this Agreement to the
contrary notwithstanding, this Agreement shall not constitute an agreement to
assign any contract or agreement, or any claim or right or any benefit arising
thereunder or resulting therefrom, if an attempted assignment thereof, without
the consent of a third party thereto, would constitute a breach thereof or would
in any way adversely affect the rights of the Alliance thereunder. If such
consent is not obtained, or if an attempted assignment thereof would be
ineffective or would affect the rights thereunder so that the Alliance would not
receive all such rights, Bank One and FDC will cause Alpha and the Alliance to
cooperate, in all reasonable respects, to obtain such consent as soon as
practicable and, until such
<PAGE>
 
consent is obtained, to provide to the Alliance the benefits under any of the
foregoing to which such consent relates (with the Alliance responsible for all
the liabilities and obligations thereunder). In particular, in the event that
any such consent is not obtained prior to the Closing Date, then Bank One and
FDC will cause Alpha and the Alliance to enter into such arrangements (including
subleasing or subcontracting if permitted) to provide to all parties the
economic and operational equivalent of obtaining such consents and assigning
such contract or agreement, including the enforcement for the benefit of the
Alliance of all claims or rights arising thereunder, and the performance by the
Alliance of the obligations thereunder.

          3.8.  CLOSING COSTS; TRANSFER FEES.  The cost of any surveys, title
reports or title searches, and the recording or filing of all applicable
conveyancing instruments incurred by reason of the transfer of Contributed
Assets to the Alliance will be paid by Alpha upon the Closing.

          8.9.  OPERATIONS PRIOR TO CLOSING DATE.  Except as set forth on
Schedule 8.9 and subject to the matters contemplated by this Agreement, the
Merger Agreement, the Revised Processing Agreement and the Stockholders
Agreement, between the date hereof and the Closing Date, Bank One and FDC shall
use reasonable efforts to cause Alpha to conduct its business only in the
ordinary course and in conformity with past practice.

          8.10. INTERCOMPANY AGREEMENTS.  Bank One agrees to, or to cause its
appropriate Affiliates to, (i) terminate the tax sharing agreement between FUSA
and Alpha to the extent the parties reasonably agree portions thereof should be
terminated, (ii) terminate the registration rights agreement between Bank One
and Alpha, (iii) enter into agreements with respect to the provision to Alpha of
office space in Dallas, Texas, certain insurance coverage and a license to use
the name "First USA" and certain other trademarks and such other services as
Bank One or one of its Affiliates are providing to Alpha or its Affiliates on
economic terms consistent with arrangements in effect prior to the Closing (said
economic terms to be in effect for 12 months from and after the Closing Date and
thereafter to be subject to good faith negotiation among the parties), and (iv)
perform the unwritten agreements between Alpha and First USA Bank described in
Section 4.23 of the Company Letter referred to in the Merger Agreement, in each
case on or before the Closing to the extent practicable.

          8.11. COOPERATION ON DEBT.  If, upon the transfer of the Contributed
Assets by Alpha to the Alliance, or the assumption by Alpha of the Assumed
Liabilities, as contemplated by this Agreement, Alpha would recognize income or
gain for federal income tax purposes as a result of the amount or nature of its
indebtedness (including, without limitation, by reason of all or a portion of
its indebtedness being treated as Member Nonrecourse Debt), then prior to such
contribution and assumption, the parties hereby agree to (and to cause their
respective Affiliates to) take
<PAGE>
 
reasonable steps to avoid such income or gain.

          8.12. CERTAIN FEES.  Bank One shall cause the Alliance to pay to FDMS,
in lieu of the amounts that would otherwise have been payable to FDMS under
Section 8.24 of the Alliance Agreement, (i) $666,667 on the last day of each
month or portion thereof remaining in calendar year 1999 after the Closing Date,
(ii) $666,667 on the last day of each month in calendar year 2000, and (iii)
$750,000 on the last day of each month in calendar year 2001.


                                  ARTICLE IX

                               EMPLOYEE MATTERS

          9.1.  EMPLOYMENT OF ALPHA EMPLOYEES.  The employment of each employee
of Alpha who is actively employed (including such employees who are on vacation)
as of the Closing shall be transferred to the Alliance effective as of the
Closing at the same base compensation and wage levels as in effect immediately
preceding the Closing. Notwithstanding anything herein to the contrary, nothing
in this Agreement shall create any obligation on the part of the Alliance or any
of its Affiliates to continue the employment of any employee for any definite
period following the Closing. The Alliance shall offer employment (or severance
benefits if such individual's position is no longer available as allowed by
applicable law) to any individual who was an employee of Alpha who is on sick or
disability leave or who is on an approved leave of absence as of the Closing as
of the date such individual returns to work. The persons who become employed by
the Alliance pursuant to this paragraph shall be referred to herein as
"Transferred Employees."

          9.2.  MAINTENANCE OF EMPLOYEE BENEFITS PLANS.  Effective as of the
Closing Date and until such time as the Alliance implements its own benefit
plans,, FDC, Bank One and the Alliance shall take any reasonable actions
necessary (including but not limited to plan amendment, governmental notices,
etc.) to maintain the participation of the Transferred Employees in the plans,
programs, agreements or arrangements which covered the Transferred Employees as
of the Closing Date.

          9.3.  BONUSES.  The Alliance shall assume all obligations and
liabilities for bonuses and incentive payments in connection with the relevant
bonus programs of Alpha in effect immediately prior to the 
<PAGE>
 
Closing Date and shall cause the payment of such bonuses or incentive payments,
if any, to be made in accordance with the terms of such plans consistent with
past practice.

          9.4.  VACATION AND SICK LEAVE.  The Alliance shall credit each
Transferred Employee with the number of unused vacation days and sick leave
credited to such individual through the Closing Date under the applicable
vacation and sick leave policies of Alpha and shall permit or cause Transferred
Employees to be permitted to use such vacation days and sick leave.

          9.5.  WORKERS' COMPENSATION.  The Alliance shall assume the obligation
and liability for any workers' compensation or similar workers' protection
claims with respect to any person who was an Alpha employee.


          9.6.  EMPLOYEES OF ALLIANCE MEMBERS.  At the present time both Bank
One, POS and FDMS have employees that provide services in connection with the
Alliance business, although none of such employees are employees of the
Alliance. Bank One and FDC acknowledge that subsequent to the Closing, the
Alliance management will decide whether or not they wish to offer employment to
any of these employees of Bank One, POS or FDMS. In the event that such a
decision to offer employment is made, the Alliance shall be under no
restrictions regarding offering employment to individuals who are dedicated 
full-time to the Alliance, and Bank One and FDC shall cooperate, and shall cause
their respective Affiliates, to cooperate, in facilitating the transfer of such
employees to the Alliance.


                                   ARTICLE X

                   INDEMNIFICATION; PAYMENT OF CERTAIN COSTS

          10.1. INDEMNIFICATION BY FDC.  FDC shall indemnify and hold harmless
Bank One and any of its Affiliates from and against any and all Losses and
Expenses, whether or not litigation is commenced, imposed upon, incurred by or
asserted against Bank One or any of its Affiliates in connection with or arising
from the breach by FDC of any representation,
<PAGE>
 
warranty, covenant or agreement of FDC in this Agreement, provided, however,
that FDC shall not be required to indemnify or hold Bank One or any of its
Affiliates harmless from or against any such Losses or Expenses to the extent
that such Losses or Expenses arise as a result of Bank One's or any of its
Affiliates' own negligence, willful misconduct or breach of any of its
representations, warranties or obligations pursuant to this Agreement.

          10.2.  INDEMNIFICATION BY BANK ONE.  Bank One shall indemnify and hold
harmless FDC and its Affiliates from and against any and all Losses and
Expenses, whether or not litigation is commenced, imposed upon, incurred by or
asserted against FDC or its Affiliates in connection with or arising from the
breach by Bank One of any representation, warranty, covenant or agreement of
Bank One in this Agreement, provided, however, that Bank One shall not be
required to indemnify or hold FDC or any of its Affiliates harmless from or
against any such Losses or Expenses to the extent that such Losses or Expenses
arise as a result of FDC's or one of its Affiliates' own negligence, willful
misconduct or breach of any of its representations, warranties or obligations
pursuant to this Agreement.

          10.3.  NOTICE OF CLAIMS.  (a)  If either Bank One, FDC or an Affiliate
of either party (each an "Indemnified Party")shall seek indemnification
hereunder, such Indemnified Party shall give promptly to the party obligated to
provide indemnification to such Indemnified Party (the "Indemnitor") a notice (a
"Claim Notice") describing in reasonable detail the facts giving rise to any
claim for indemnification hereunder and shall include in such Claim Notice (if
then known) the amount or the method of computation of the amount of such claim,
and a reference to the provision of this Agreement or any other agreement,
document or instrument executed hereunder or in connection herewith upon which
such claim is based; provided, however, that a Claim Notice in respect of any
action at law or suit in equity by or against a third Person as to which
indemnification will be sought shall be given promptly after the action or suit
is commenced.

          (b)  In calculating any Loss or Expense there shall be deducted (i)
any insurance recovery in respect thereof (and no right of subrogation shall
accrue hereunder to any insurer) and (ii) the amount of any tax
<PAGE>
 
benefit to the Indemnified Party (or any of its Affiliates) with respect to such
Loss or Expense (after giving effect to the tax effect of receipt of the
indemnification payments).

          (c)  After the giving of any Claim Notice pursuant hereto, the amount
of indemnification to which an Indemnified Party shall be entitled under this
Article X shall be determined: (i) by the written agreement between the
Indemnified Party and the Indemnitor; (ii) by a final judgment or decree of any
court of competent jurisdiction; or (iii) by any other means to which the
Indemnified Party and the Indemnitor shall agree. The judgment or decree of a
court shall be deemed final when the time for appeal, if any, shall have expired
and no appeal shall have been taken or when all appeals taken shall have been
finally determined. The Indemnified Party shall have the burden of proof in
establishing the amount of Loss and Expense suffered by it.

          10.4.  THIRD PERSON CLAIMS.  (a)  In order for an Indemnified Party to
be entitled to any indemnification provided for under this Agreement in respect
of, arising out of or involving a claim or demand made by any third Person
against an Indemnified Party, such Indemnified Party must notify the Indemnitor
in writing, and in reasonable detail, of the third Person claim within 10
Banking Days after receipt by such Indemnified Party of written notice of the
third Person claim. Thereafter, the Indemnified Party shall deliver to the
Indemnitor, within 10 Banking Days after the Indemnified Party's receipt
thereof, copies of all notices and documents (including court papers) received
by the Indemnified Party relating to the third Person claim. Notwithstanding the
foregoing, should an Indemnified Party be physically served with a complaint
with regard to a third Person claim, the Indemnified Party must notify the
Indemnitor and deliver a copy of the complaint within 10 Banking Days after
receipt thereof and shall deliver to the Indemnitor within 10 Banking Days after
the receipt of such complaint copies of notices and documents (including court
papers) received by the Indemnified Party relating to the third Person claim.

          (b)  In the event of the initiation of any legal proceeding, claim or
demand against the Indemnified Party by a third Person, the Indemnitor shall
have the sole and absolute right after the receipt of
<PAGE>
 
notice, at its option and at its own expense, to be represented by counsel
reasonably acceptable to the Indemnified Party and to control, defend against,
negotiate, settle or otherwise deal with any proceeding, claim, or demand which
relates to any Loss or Expense indemnified against hereunder; provided, however,
that the Indemnified Party may participate in any such proceeding with counsel
of its choice and at its expense. The parties hereto agree to cooperate fully
with each other in connection with the defense, negotiation or settlement of any
such legal proceeding, claim or demand. To the extent the Indemnitor elects not
to defend such proceeding, claim or demand, and the Indemnified Party defends
against or otherwise deals with any such proceeding, claim or demand, the
Indemnified Party may retain counsel, at the expense of the Indemnitor, and
control the defense of such proceeding. Neither the Indemnitor nor the
Indemnified Party may settle any such proceeding which settlement obligates the
other party to pay money, to perform obligations or to admit liability without
the consent of the other party, such consent not to be unreasonably withheld.
After any final judgment or award shall have been rendered by a court,
arbitration board or administrative agency of competent jurisdiction and the
time in which to appeal therefrom has expired, or a settlement shall have been
consummated, or the Indemnified Party and the Indemnitor shall arrive at a
mutually binding agreement with respect to each separate matter alleged to be
indemnified by the Indemnitor hereunder, the Indemnified Party shall forward to
the Indemnitor notice of any sums due and owing by it with respect to such
matter and the Indemnitor shall pay all of the sums so owning to the Indemnified
Party by wire transfer, certified or bank cashier's check within 30 days after
the date of such notice.

          10.5.  LIMITATION.  No failure of the Indemnified Party to give the
Indemnitor timely notice as required by Section 10.3 or 10.4 above shall affect
such Indemnified Party's right to indemnification hereunder unless, and then
only to the extent that the rights of the Indemnitor to defend against such
claim have been prejudiced thereby.

                                  ARTICLE XI

                                  TERMINATION

          11.1.  TERMINATION.  Anything contained in this Agreement to the
contrary notwithstanding, this Agreement may be terminated at any time prior to
the Closing Date:

          (a)  by the mutual written consent of Bank One and FDC;

          (b)  by Bank One or FDC if the Merger Agreement shall be terminated
     pursuant to its terms;

          (c)  by Bank One or FDC if the transactions contemplated by the Merger
     Agreement shall not have been consummated on or before October 1, 1999; and

          (d)  by Bank One or FDC if the Closing shall not have occurred on or
     before October 1, 1999.

          11.2.  NOTICE OF TERMINATION.  Any party desiring to terminate this
Agreement pursuant to Section 11.1 shall give written notice of such termination
to the other party to this Agreement.

          11.3.  EFFECT OF TERMINATION.  In the event that this Agreement shall
be terminated pursuant to this Article XI, all further obligations of the
parties under this Agreement (other than Sections 12.8 and 12.11) shall be
terminated without further liability of any party to the other, provided that
nothing herein shall relieve any party from liability for its willful breach of
this Agreement.

                                  ARTICLE XII

                           MISCELLANEOUS PROVISIONS

          12.1.  COUNTERPARTS.  This Agreement may be executed in several
counterparts, each of which will be deemed an original, but all of which
together will constitute one and the same instrument.

          12.2.  ENTIRE AGREEMENT.  This Agreement, the Operating Agreement, the
Revenue Sharing Agreement and the Revised Processing Agreement and the Exhibits,
Annexes and Schedules hereto and thereto constitute the entire agreement among
the parties hereto and contain all of the agreements among such parties with
respect to the subject matter
<PAGE>
 
hereof and thereof. This Agreement, the Operating Agreement, the Revenue Sharing
Agreement and the Revised Processing Agreement and the Exhibits, Annexes and
Schedules hereto and thereto supersede any and all other agreements, either oral
or written, between such parties with respect to the subject matter hereof and
thereof.

          12.3.  PARTIAL INVALIDITY.  Wherever 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 provision shall be ineffective to the extent, but only to the
extent, of such invalidity, illegality or unenforceability without invalidating
the remainder of such invalid, illegal or unenforceable provision or provisions
or any other provisions hereof, unless such a construction would be
unreasonable.

          12.4.  AMENDMENT.  Except as expressly provided herein, this Agreement
may be amended only by a written agreement executed by each of FDC and Bank One.

          12.5.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO ITS CONFLICTS OF LAW DOCTRINE, EXCEPT TO THE EXTENT THE DELAWARE
LIMITED LIABILITY COMPANY ACT IS CONTROLLING.

          12.6.  WAIVER.  Any term or provision of this Agreement may be waived,
or the time for its performance may be extended, by the party or parties
entitled to the benefit thereof. Any such waiver shall be validly and
sufficiently authorized for the purposes of this Agreement if, as to any party,
it is authorized in writing by an authorized representative of such party. The
failure of any party hereto to enforce at any time any provision of this
Agreement shall not be construed to be a waiver of such provision, nor in any
way to affect the validity of this Agreement or any part hereof or the right of
any party thereafter to enforce each and every such provision. No waiver of any
breach of this Agreement shall be held to constitute a waiver of any other or
subsequent breach.
<PAGE>
 
          12.7.  FURTHER ASSURANCES.  In connection with this Agreement, the
Operating Agreement, the Revenue Sharing Agreement and the Revised Processing
Agreement and the transactions contemplated hereby and thereby, after the
Closing each of FDC and Bank One shall execute and deliver, or use reasonable
best efforts to cause to be executed and delivered (whether by Alpha or by any
of its other Affiliates), any additional documents and instruments, and each
will perform, or use reasonable best efforts to cause to be performed (whether
by Alpha or by any of its other Affiliates), any additional acts that may be
necessary or appropriate to effectuate and perform the provisions of this
Agreement, the Operating Agreement, the Revenue Sharing Agreement, the Revised
Processing Agreement and any other agreement contemplated hereby to which it or
any of its Affiliates is a party and the transactions contemplated hereby and
thereby.

          12.8.  EXPENSES.  Each of FDC and Bank One shall pay its own legal,
accounting and other expenses incident to its negotiation and preparation of

          12.9.  SURVIVAL OF OBLIGATIONS.  All representations, warranties,
covenants and obligations contained in this Agreement shall survive the
consummation of the transactions contemplated by this Agreement; provided,
however, that the representations and warranties contained in Section 6.1(e),
(f) and (g) shall terminate on the Closing Date and the other representations
and warranties contained in Section 6.1 and Section 6.2 shall terminate on the
third anniversary of the Closing Date.

          12.10. SUCCESSORS AND ASSIGNS.  (a) The rights of either party under
this Agreement shall not be assignable by such party hereto without the written
consent of the other.

          (b)  This Agreement shall be binding upon and inure to the benefit of
the parties hereto and their successors and permitted assigns. The successors
and permitted assigns hereunder shall include without limitation, any permitted
assignee as well as the successors in interest to such permitted assignee
(whether by merger, liquidation (including successive mergers or liquidations)
or otherwise). Nothing in this Agreement, expressed or implied, is intended or
shall be construed to confer upon any Person other than the parties and
successors and assigns 
<PAGE>
 
permitted by this Section 12.10 any right, remedy or claim under or by reason of
this Agreement.

          12.11. CONFIDENTIAL NATURE OF INFORMATION.  Each party agrees that it
will treat in confidence during the period prior to the Closing Date all
documents, materials and other information which it shall have obtained
regarding the other party and its Affiliates during the course of the
negotiations leading to the consummation of the transactions contemplated hereby
(whether obtained before or after the date of this Agreement), the investigation
provided for herein and the preparation of this Agreement and other related
documents, and, in the event the transactions contemplated hereby shall not be
consummated, each party will return to the other party all copies of nonpublic
documents and materials which have been furnished in connection therewith. Such
documents, materials and information shall not be communicated to any third
Person (other than counsel, accountants or financial advisors of FDC and Bank
One). No other party shall use any confidential information in any manner
whatsoever except solely for the purpose of evaluating the transactions. The
obligation of each party to treat such documents, materials and other
information in confidence shall not apply to any information which (i) is or
becomes available to such party from a source other than such party provided
such source is not known by the recipient to be subject to an obligation of
confidentiality with respect to such information, (ii) is or becomes available
to the public other than as a result of disclosure by such party or its agents,
(iii) is required to be disclosed under applicable law or judicial process, but
only to the extent it must be disclosed, or (iv) following prior written notice
to the other party disclosing the nature of the proposed disclosure and the
reasons such disclosure is required, such party reasonably deems necessary to
disclose to obtain any of the consents or approvals contemplated hereby.

          12.12. INFORMAL DISPUTE RESOLUTION.  Any dispute, controversy or claim
between FDC and Bank One, including any dispute, controversy or claim involving
their respective Affiliates, arising from or in connection with this Agreement
or the relationship of the parties under this Agreement, whether based on
contract, tort, common law, equity, statute, regulation, order or otherwise
("Dispute") shall be resolved as follows:

          (a)  Upon written request of either party, each party will appoint a
     designated representative whose task it will be to meet for the purpose of
     endeavoring to resolve such Dispute.
<PAGE>
 
          (b)  The designated representatives shall meet as often as the parties
     reasonably deem necessary to discuss the problem in an effort to resolve
     the Dispute without the necessity of any formal proceeding. During the
     discussions, all reasonable requests by a party to another party for non-
     privileged information reasonably related to the Dispute shall be honored
     in order that each party may be fully advised of the other party's
     position.

          (c)  Formal proceedings for the resolution of a Dispute may not be
     commenced until the earlier of:

               (i)   the designated representatives concluding in good faith
          that amicable resolution through continued negotiation of the matter
          does not appear likely; or

               (ii)  the expiration of the fifteen (15) day period immediately
          following the initial request to negotiate the Dispute;

provided, however, that this Section 12.12 will not be construed to prevent a
party from instituting formal proceedings earlier to avoid the expiration of any
applicable limitations period, to preserve a superior position with respect to
other creditors, or to seek temporary or preliminary injunctive relief pursuant
to Section 12.14.

          12.13.  ARBITRATION.

          (a)  If the parties are unable to resolve any Dispute as contemplated
     by Section 12.12, such Dispute shall be submitted to mandatory and binding
     arbitration at the election of any disputing party (the "Disputing Party").
     It is the intent of the parties that the arbitration be structured in such
     a way as to minimize costs. Except as otherwise provided in this Section
     12.13, the arbitration shall be pursuant to the Commercial Arbitration
     Rules of the American Arbitration Association (the "AAA").

          (b)  To initiate the arbitration, the Disputing Party shall notify the
     other party in writing (the "Arbitration Demand"), which shall (i) describe
     in reasonable detail the nature of the Dispute, (ii) state the amount of
     the claim, (iii) specify the requested
<PAGE>
 
     relief and (iv) name an arbitrator who (A) has been licensed to practice
     law in the U.S. for at least ten years, (B) is not then an employee of Bank
     One or FDC or an employee of an Affiliate of Bank One or FDC, and (C) is
     experienced in representing clients in connection with mergers and
     acquisitions and the subject matter of the Dispute (the "Basic
     Qualifications"). Within fifteen (15) days after the other party's receipt
     of the Arbitration Demand, such other party shall file and serve on the
     Disputing Party, a written statement (i) answering the claims set forth in
     the Arbitration Demand, including any affirmative defenses of such party;
     (ii) asserting any counterclaim, which shall (A) describe in reasonable
     detail the nature of the Dispute relating to the counterclaim, (B) state
     the amount of the counterclaim, and (C) specify the requested relief; and
     (iii) either accepting the arbitrator proposed by the Disputing Party as
     the sole arbitrator for the proceedings or naming a second arbitrator
     satisfying the Basic Qualifications. The Disputing Party shall notify the
     other party within two (2) days whether the Disputing Party accepts the
     arbitrator proposed by the other party as the sole arbitrator for the
     proceedings or rejects such arbitrator and proposes an alternate
     arbitrator, in which event within fifteen (15) days thereafter, the two
     arbitrators so named by each party will select a third neutral arbitrator
     from a list provided by the AAA of potential arbitrators who satisfy the
     Basic Qualifications and who have no past or present relationships with the
     parties or their counsel, except as otherwise disclosed in writing to and
     approved by the parties. The arbitration will be heard by a panel
     consisting of either one arbitrator or three arbitrators, as determined in
     accordance with this paragraph (b) (the "Arbitration Panel") with, in the
     case of three arbitrators, the third arbitrator so chosen serving as the
     chairperson of the Arbitration Panel. Decisions of a majority of the
     members of the Arbitration Panel shall be determinative.

          (c)  The arbitration hearing shall be held in Chicago, Illinois.
<PAGE>
 
     The Arbitration Panel is specifically authorized to render partial or full
     summary judgment as provided for in the Federal Rules of Civil Procedure.
     In the event summary judgment or partial summary judgment is granted, the
     non-prevailing party may not raise as a basis for a motion to vacate an
     award that the Arbitration Panel failed or refused to consider evidence
     bearing on the dismissed claim(s) or issue(s). The Federal Rules of
     Evidence shall apply to the arbitration hearing.

     The party bringing a particular claim or asserting an affirmative defense
     will have the burden of proof with respect thereto. The arbitration
     proceedings and all testimony, filings, documents and information relating
     to or presented during the arbitration proceedings shall be deemed to be
     information subject to the confidentiality provisions of this Agreement.
     The Arbitration Panel will have no power or authority, under the Commercial
     Arbitration Rules of the AAA or otherwise, to relieve the parties from
     their agreement hereunder to arbitrate or otherwise to amend or disregard
     any provision of this Agreement, including the provisions of this Section
     12.13.

          (d)  Should an arbitrator refuse or be unable to proceed with
     arbitration proceedings as called for by this Section 12.13, the arbitrator
     shall be replaced by the party who selected such arbitrator (and approved
     by the other party if in a sole arbitrator proceeding), or if such
     arbitrator was selected by the two party-appointed arbitrators, by such two
     party-appointed arbitrators selecting a new third arbitrator in accordance
     with Section 12.13(b). Each such replacement arbitrator shall satisfy the
     Basic Qualifications. If an arbitrator is replaced pursuant to this Section
     12.13(d) after the arbitration hearing has commenced, then a rehearing
     shall take place in accordance with the provisions of this Section 12.13
     and the Commercial Arbitration Rules of the AAA.

          (e)  At the time of granting or denying a motion for summary judgment
     as provided for in paragraph (c) of this Section 12.13 and within fifteen
     (15) days after the closing of the arbitration hearing, the Arbitration
     Panel shall prepare and distribute to the parties a writing setting forth
     the Arbitration Panel's finding of facts and conclusions of law relating to
     the Dispute, including the reasons for the giving or denial of any award.
     The findings and conclusions
<PAGE>
 
     and the award, if any, shall be deemed to be information subject to the
     confidentiality provisions of this Agreement.

          (f)  The Arbitration Panel is instructed to schedule promptly all
     discovery and other procedural steps and otherwise to assume case
     management initiative and control to effect an efficient and expeditious
     resolution of the Dispute. Each party's presentation at the arbitration
     hearing shall be limited to fourteen (14) hours, and the hearing shall be
     completed within ten (10) Banking Days. Summaries of any expert testimony,
     along with copies of all documents to be submitted as Exhibits shall be
     exchanged as soon as possible and in all events at least ten (10) Banking
     Days before the arbitration hearing under procedures set up by the
     Arbitration Panel. Except as otherwise specified herein, there shall be no
     discovery or dispositive motion practice except as may be permitted by the
     Arbitration Panel, who may authorize only such discovery as is shown to be
     necessary to insure a fair hearing. No discovery or motions permitted by
     the Arbitration Panel shall in any way alter the time limits specified
     herein. Both parties shall continue to perform their respective obligations
     in accordance with the terms of this Agreement and any agreements
     contemplated hereby during any arbitration proceeding. The fact that
     arbitration has commenced shall not impair the exercise of any termination
     rights set forth in this Agreement. The Arbitration Panel is authorized to
     issue monetary sanctions against either party if, upon a showing of good
     cause, such party is unreasonably delaying the proceeding.

          (g)  Any award rendered by the Arbitration Panel will be final,
conclusive and binding upon the parties and any judgment thereon may be entered
and enforced in any court of competent jurisdiction. The Arbitration Panel may
not award punitive damages or any other relief not contemplated by this
Agreement. In particular, the Arbitration Panel may not order the dissolution,
liquidation or other termination of the Company except as specifically
contemplated by the
<PAGE>
 
Formation Agreement.

          (h)  Each party will bear a pro rata share of all fees, costs and
expenses of the arbitrators, and notwithstanding any law to the contrary, each
party will bear all the fees, costs and expenses of its own attorneys, experts
and witnesses; provided, however, that in connection with any judicial
proceeding to compel arbitration pursuant to this Agreement or to confirm,
vacate or enforce any award rendered by the Arbitration Panel, the prevailing
party in such a proceeding will be entitled to recover reasonable attorneys'
fees and expenses incurred in connection with such proceeding, in addition to
any other relief to which it may be entitled.

          12.14.  JUDICIAL PROCEDURE.  Nothing in Sections 12.12 or 12.13 shall
be construed to prevent any party from seeking from a court a temporary
restraining order or other temporary or preliminary relief pending final
resolution of a Dispute pursuant to such Sections 12.12 or 12.13.

          12.15.  TERMINATION OF ALLIANCE AGREEMENT.  Except with respect to the
provisions of Sections 3.1(d), 3.1(e), 3.2(d) and 3.2(e) of the Alliance
Agreement and the obligations of the parties under Article V of the Alliance
Agreement with respect to such sections, the Alliance Agreement shall be
terminated in all respects as of the Closing Date.

          IN WITNESS WHEREOF, this Agreement has been duly executed and
delivered by the duly authorized officers of the parties hereto as of the date
first above written.
