ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law provides that a Delaware
corporation may indemnify any person against expenses, judgments, fines and
settlements actually and reasonably incurred by any such person in connection
with a threatened, pending or completed action, suit or proceeding to which
such person is a party or is threatened to be made a party by reason of the
fact that he is or was a director, officer, employee or agent of such
corporation, provided, that (i) he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and (ii) with respect to any criminal action or proceeding, he had
no reasonable cause to believe his conduct was unlawful. If the action or suit
is by or in the right of the corporation, the corporation may indemnify any
such person against expenses actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted
in good faith and in a manner he reasonably believed to be in or not opposed
to the best interests of the corporation, except that no indemnification may
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the corporation for negligence or
misconduct in the performance of his duty to the corporation, unless and only
to the extent that the Delaware Court of Chancery or the court in which the
action or suit is brought determines upon application that, despite the
adjudication of liability but in view of all of the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
as the court deems proper.
 
  As permitted under the Delaware General Corporation Law, the Registrant's
Certificate of Incorporation and Bylaws limit the personal liability of its
directors for violations of their fiduciary duty.
 
  Under certain circumstances provided in Article VIII of the Registrant's
Bylaws, the Registrant will indemnify any director or officer or any former
director or officer of the Registrant or any other corporation or enterprise
(if serving at the request of the Registrant) against expenses, liability and
loss (including attorney's fees, judgments, fines, ERISA excise taxes or
penalties and amounts to be paid in settlement) actually incurred or suffered
by such person by reason of the fact that he is or was such director or
officer in connection with any threatened, pending or completed action, suit
or proceeding, whether civil, criminal, administrative or investigative. A
copy of the Registrant's Bylaws is included herein as Exhibit 3.1(ii).

ITEM 17. UNDERTAKINGS
 
  (a) EQUITY OFFERINGS OF NONREPORTING REGISTRANTS. The undersigned Registrant
hereby undertakes to provide to the Underwriters at the closing specified in
the Underwriting Agreement, certificates in such denominations and registered
in such names as required by the Underwriters to permit prompt delivery to each
purchaser.
 
  (b) INDEMNIFICATION. Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the Company pursuant to the foregoing provisions or
otherwise, the Company has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other that the payment by
the Company of expenses incurred or paid by a director, officer or controlling
person of the Company in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
  (c) RULE 430A PROSPECTUSES. The undersigned Registrant hereby undertakes
that:
 
    (1) For the purpose of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this Registration Statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new Registration Statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

Goldman, Sachs & Co.,
Montgomery Securities,
Salomon Brothers Inc,
 As representatives of the several Underwriters
  named in Schedule I hereto,
c/o Goldman, Sachs & Co.
85 Broad Street
New York, New York 10004


Ladies and Gentlemen:

  BA Merchant Services, Inc., a Delaware corporation (the "Company"), proposes,
subject to the terms and conditions stated herein, to issue and sell to the
Underwriters named in Schedule I hereto (the "Underwriters") an aggregate of
11,200,000 shares (the "Firm Shares") and, at the election of the Underwriters,
up to 1,680,000 additional shares (the "Optional Shares") of Class A Common
Stock, par value $.01 per share ("Stock") of the Company (the Firm Shares and
the Optional Shares that the Underwriters elect to purchase pursuant to Section
3 hereof being collectively called the "Shares").  The Company was organized to
hold and operate the merchant processing businesses of Bank of America National
Trust and Savings Association, a national banking association (the "Bank"), and
the Seafirst Bank Division of Bank of America NW, N.A. ("Seafirst").  The Bank
and Seafirst are wholly-owned subsidiaries of BankAmerica Corporation, a
Delaware corporation ("BankAmerica").

  It is understood and agreed to by all parties that the Company is concurrently
entering into an agreement (the "International Underwriting Agreement")
providing for the sale by the Company of up to a total of 3,220,000 shares of
Stock (the "International Shares"), including the overallotment option
thereunder, through arrangements with certain underwriters outside the United
States (the "International Underwriters"), for whom Goldman Sachs International,
Montgomery Securities and Salomon Brothers International Limited are acting as
lead managers.  Anything herein or therein to the contrary notwithstanding, the
respective closings under this Agreement and the International Agreement are
hereby expressly made conditional on one another.  The Underwriters hereunder
and the International Underwriters are simultaneously entering into an Agreement
between U.S. and International Underwriting Syndicates (the "Agreement between
Syndicates") which provides, among other things, for the transfer of shares of
Stock between the two syndicates.  Two forms of prospectus are to be used in
connection with the offering and sale of shares of Stock contemplated by the
foregoing, one relating to the Shares hereunder and the other relating to the
International Shares.  The latter form of prospectus will be identical to the
former except for certain substitute pages. 
<PAGE>
 
Except as used in Sections 3, 4, 5, 10 and 12 herein, and except as the context
may otherwise require, references hereinafter to the Shares shall include all
the shares of Stock which may be sold pursuant to either this Agreement or the
International Underwriting Agreement, and references herein to the "U.S.
Prospectus" whether in preliminary or final form, and whether as amended or
supplemented, shall refer to the prospectus relating to the Shares hereunder and
references herein to the "International Prospectus" whether in preliminary or
final form, and whether as amended or supplemented, shall refer to the
prospectus relating to the International Shares.

    1.  The Company represents and warrants to, and agrees with, each of the
Underwriters that:

        (a)  A registration statement on Form S-1 (File No. 333-13985) (the
     "Initial Registration Statement") in respect of the Shares has been filed
     with the Securities and Exchange Commission (the "Commission"); the Initial
     Registration Statement and any post-effective amendment thereto, each in
     the form heretofore delivered to you, and, excluding exhibits thereto, to
     you for each of the other Underwriters, have been declared effective by the
     Commission in such form; other than a registration statement, if any,
     increasing the size of the offering (a "Rule 462(b) Registration
     Statement"), filed pursuant to Rule 462(b) under the Securities Act of
     1933, as amended (the "Act"), which became effective upon filing, no other
     document with respect to the Initial Registration Statement has heretofore
     been filed with the Commission; and no stop order suspending the
     effectiveness of the Initial Registration Statement, any post-effective
     amendment thereto or the Rule 462(b) Registration Statement, if any, has
     been issued and no proceeding for that purpose has been initiated or
     threatened by the Commission (any preliminary prospectus included in the
     Initial Registration Statement or filed with the Commission pursuant to
     Rule 424(a) of the rules and regulations of the Commission under the Act,
     is hereinafter called a "Preliminary Prospectus"; the various parts of the
     Initial Registration Statement, including all exhibits thereto and
     including the information contained in the form of final U.S. Prospectus
     filed with the Commission pursuant to Rule 424(b) under the Act in
     accordance with Section 6(a) hereof and deemed by virtue of Rule 430A under
     the Act to be part of the Initial Registration Statement at the time it was
     declared effective or such part of the Rule 462(b) Registration Statement,
     if any, became or hereafter becomes effective, each as amended at the time
     such part of the registration statement became effective, are hereinafter
     collectively called the "Registration Statement"; and such final U.S.
     Prospectus, in the form first filed pursuant to Rule 424(b) under the Act,
     collectively with the International Prospectus is hereinafter called the
     "Prospectus").

        (b)  No order preventing or suspending the use of any Preliminary
     Prospectus has been issued by the Commission, and each Preliminary
     Prospectus, at the time of filing thereof, conformed in all material
     respects to the requirements of the Act and the rules and regulations of
     the Commission thereunder, and did not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
     however, that this representation and warranty shall not apply to any
     statements or omissions made in reliance upon and in conformity with
     information furnished in writing to the Company by an Underwriter through
     Goldman, Sachs & Co. expressly for use therein;

                                      -2-

        (c)  The Registration Statement conforms, and the Prospectus and any
     further amendments or supplements to the Registration Statement or the
     Prospectus will conform, in all material respects to the requirements of
     the Act and the rules and regulations of the Commission thereunder and do
     not and will not, as of the applicable effective date as to the
     Registration Statement and any amendment thereto and as of the applicable
     filing date as to the Prospectus and any amendment or supplement thereto,
     contain an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company
     by an Underwriter through Goldman, Sachs & Co. expressly for use therein;

        (d)  Neither the Company nor any of its subsidiaries has sustained since
     the date of the latest audited financial statements included in the
     Prospectus any material loss or interference with its business from fire,
     explosion, flood or other calamity, whether or not covered by insurance, or
     from any labor dispute or court or governmental action, order or decree,
     otherwise than as set forth or contemplated in the Prospectus; and, since
     the respective dates as of which information is given in the Registration
     Statement and the Prospectus, there has not been any change in the capital
     stock or long-term debt of the Company and there has been no material
     change in the working capital and no increase in the long-term debt of the
     Company or any material adverse change, or any development involving a
     prospective material adverse change, in or affecting the general affairs,
     management, financial position, stockholders' equity or results of
     operations of the Company and its subsidiaries, taken as a whole, otherwise
     than as set forth or contemplated in the Prospectus;

        (e)  The Company and its subsidiaries own no real property and have good
     and marketable title to all personal property owned by them, free and clear

     and do not materially interfere with the use made and proposed to be made
     of such property by the Company and its subsidiaries; and any real property
     and buildings held under lease by the Company and its subsidiaries are held
     by them under valid, subsisting and enforceable leases or subleases with

     Company and its subsidiaries;

     a foreign corporation for the transaction of business and is in good
     standing under the laws of each other jurisdiction in which it owns or
     leases properties or conducts any business so as to require such
     qualification, or is subject to no material liability or disability by
     reason of the failure to be so qualified in any such jurisdiction;

     non-assessable and will conform in all material respects to the description

     Such time and date for delivery of the Firm Shares is herein called the

     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made when such Prospectus
     is delivered, not misleading, or, if for any other reason it shall be

     furnished to you their written opinion (a draft of each such opinion is
     attached as Annex II(b) hereto), dated such Time of Delivery, in form and
     substance reasonably satisfactory to you, to the effect that:

              (i) The Company has been duly incorporated and is validly existing
     as a corporation in good standing under the laws of the State of Delaware,
     with full corporate power and authority to own its properties and conduct
     its business as described in the Prospectus;

              (ii) The Company has been duly qualified as a foreign corporation
     for the transaction of business and is in good standing under the laws of
     each other jurisdiction in which it owns or leases properties or conducts
     any business so as to require such qualification, or is subject to no
     material liability or disability by reason of failure to be so qualified in
     any such jurisdiction (such counsel being entitled to rely in respect of
     the opinion in this clause upon opinions of local counsel and in respect of
     matters of fact upon certificates of officers of the Company, provided that
     such counsel shall state that they believe that both you and they are
     justified in relying upon such opinions and certificates);

              (iii)  The Company has an authorized capitalization as set forth
     in the Prospectus, and all of the issued shares of capital stock of the
     Company (including the Shares being delivered at such Time of Delivery)
     have been duly and validly authorized and issued and are fully paid and
     nonassessable; and the Shares conform to the description of the Stock
     contained in the Prospectus;

              (iv) To the best of such counsel's knowledge and other than as set
     forth in the Prospectus, there are no legal or governmental proceedings
     pending to which the Company or any of its subsidiaries is a party or of
     which any property of the Company or any of its subsidiaries is the subject
     that is of a character required to be disclosed in the Registration
     Statement which is not adequately disclosed therein; and, to the best of
     such counsel's knowledge, no such proceedings are threatened or
     contemplated by governmental authorities or threatened by others;

              (v) This Agreement and the International Underwriting Agreement
     have been duly authorized, executed and delivered by the Company and
     BankAmerica;

             (vi) The Corporate Opportunities Agreement, the License Agreement,

     Agreement, the lease agreement and the Tax Allocation Agreement, each as
     described in the Prospectus under the caption "Relationship with
     BankAmerica," have been duly authorized, executed and delivered by the
     Company and BankAmerica, the Bank and Seafirst, as applicable, and each
     constitutes a valid and legally binding agreement, enforceable in
     accordance with its terms by the Company, subject, as to enforcement, to
     bankruptcy, insolvency, reorganization and other laws of general
     applicability relating to or affecting creditors' rights and to general
     equity principles;

             (vii)  The issue and sale of the Shares being delivered at such
     Time of Delivery by the Company, the compliance by the Company with all of
     the provisions of this Agreement and the International Underwriting
     Agreement, the consummation of the transactions herein and therein
     contemplated and the performance by the Company, BankAmerica, the Bank and
     Seafirst of their respective obligations under the Corporate Opportunities
     Agreement, the License Agreement, the Sponsorship Agreement, the
     Administrative Services Agreement, the Marketing Agreement, the lease
     agreement and the Tax Allocation Agreement, each as described in the
     Prospectus under the caption "Relationship with BankAmerica," will not
     result in any violation of the provisions of the Certificate of
     Incorporation or By-laws or other charter documents of the Company or any
     statute or any order, rule or regulation known to such counsel of any court
     or government agency or body having jurisdiction over the Company or any of
     its subsidiaries or any of their properties;

              (viii)  To such counsel's knowledge, neither the Company nor any
     of its subsidiaries is in violation of its Certificate of Incorporation or
     By-laws or in default in the performance or observance of any material
     obligation, agreement, covenant or condition contained in any indenture,
     mortgage, deed of trust, loan agreement, lease or other agreement or
     instrument to which it is a party or by which it or any of its properties
     may be bound;

              (ix) The statements set forth in the Prospectus under the caption
     "Description of Capital Stock", insofar as they purport to constitute a
     summary of the terms of the Stock, in the International Prospectus under
     the caption "Certain United States Tax Considerations for Non-U.S. Holders
     of Common Stock", and in the Prospectus under the captions "Relationship
     with BankAmerica" and "Underwriting", insofar as they purport to describe
     the provisions of the laws and documents referred to therein, are accurate,
     complete and fair in all material respects;

              (x) The Company is not an "investment company" or an entity
     "controlled" by an "investment company", as such terms are defined in the
     Investment Company Act; and

              (xi) The Registration Statement and the Prospectus and any further
     amendments and supplements thereto made by the Company prior to such Time
     of Delivery (other than the financial statements and related schedules and
     other financial information contained therein or that should have been
     contained therein, as to which such counsel need express no opinion) comply
     as to form in all material respects with the requirements of the Act and
     the rules and regulations thereunder, although they do not assume any
     responsibility for the accuracy, completeness or fairness of the statements
     contained in the Registration Statement or the Prospectus, except for those

                                      -12-
<PAGE>
 
     referred to in the opinion in subsection (ix) of this Section 8(c); nothing
     has come to the attention of such counsel to cause them to believe that, as
     of its effective date, the Registration Statement or any further amendment
     thereto made by the Company prior to such Time of Delivery (other than the
     financial statements and related statements and related schedules therein
     or that should have been contained therein, as to which such counsel need
     express no opinion) contained an 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 not misleading or that, as of its date, the
     Prospectus or any further amendment or supplement thereto made by the
     Company prior to such Time of Delivery (other than the financial statements
     and related schedules therein or that should have been contained therein,
     as to which such counsel need express no opinion) contained an untrue
     statement of a material fact or omitted to state a material fact necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading or that, as of such Time of Delivery,
     either the Registration Statement or the Prospectus or any further
     amendment or supplement thereto made by the Company prior to such Time of
     Delivery (other than the financial statements and related schedules therein
     or that should have been contained therein, as to which such counsel need
     express no opinion) contains an untrue statement of a material fact or
     omits to state a material fact necessary to make the statements therein, in
     the light of the circumstances under which they were made, not misleading.

              In rendering such opinion, such counsel may state that they
     express no opinion as to the laws of any jurisdiction other than the United
     States, the State of California and the corporate law of the State of
     Delaware.

          (d) Counsel for BankAmerica shall have furnished to you their written
     opinions (a draft of each such opinion is attached as Annex II(c) hereto),
     dated such Time of Delivery, in form and substance reasonably satisfactory
     to you, to the effect that:

              (i) Each subsidiary of the Company has been duly incorporated and
     is validly existing as a corporation in good standing under the laws of its
     jurisdiction of incorporation or otherwise has been duly organized and is
     in good standing under the laws of its jurisdiction of organization; and
     all of the issued shares of capital stock of each such subsidiary have been
     duly and validly authorized and issued, are fully paid and non-assessable,
     and (except for directors' qualifying shares) are owned directly or
     indirectly by the Company, free and clear of all liens, encumbrances,
     equities or claims (such counsel being entitled to rely in respect of the
     opinion in this clause upon opinions of local counsel and in respect to
     matters of fact upon certificates of officers of the Company or its
     subsidiaries, provided that such counsel shall state that they believe that
     both you and they are justified in relying upon such opinions and
     certificates);

              (ii) Any material real property and buildings held under lease by
     the Company and its subsidiaries in the States of California or Washington
     are held by them under valid, subsisting and enforceable leases or
     subleases with such exceptions as do not materially interfere with the use
     made and proposed to be made of such property and buildings by the Company
     or such subsidiary (in giving the opinion in this clause, such counsel may
     state that no examination of record titles for the purpose of such opinion
     has been made, and that they are relying upon a general review of the
     titles of the Company and its subsidiaries, upon opinions of local counsel
     and abstracts, reports and policies of title companies rendered or issued
     at or subsequent to the time of

                                      -13-
<PAGE>
 
     acquisition of such property by the Company and its subsidiaries, upon
     opinions of counsel to the lessors of such property and, in respect to
     matters of fact, upon certificates of officers of the Company and its
     subsidiaries, provided that such counsel shall state that they believe that
     both you and they are justified in relying upon such opinions, abstracts,
     reports, policies and certificates);

              (iii)  The issue and sale of the Shares being delivered at such
     Time of Delivery by the Company, the compliance by the Company and
     BankAmerica with all of the provisions of this Agreement and the
     International Underwriting Agreement, the consummation of the transactions
     herein and therein contemplated and the performance by the Company,
     BankAmerica, the Bank and Seafirst of their respective obligations under
     the Corporate Opportunities Agreement, the License Agreement, the
     Sponsorship Agreement, the Administrative Services Agreement, the Marketing
     Agreement, the lease agreement and the Tax Allocation Agreement , each as
     described in the Prospectus under the caption "Relationship with
     BankAmerica," will not conflict with or result in a breach or violation of
     any of the terms or provisions of, or constitute a default under, any
     indenture, mortgage, deed of trust, loan agreement or other agreement or
     instrument known to such counsel to which BankAmerica, the Bank, Seafirst
     or the Company is a party or by which BankAmerica, the Bank, Seafirst or
     the Company is bound or to which any of the property or assets of
     BankAmerica, the Bank, Seafirst or the Company is subject, nor will such
     action result in any violation of the provisions of the Certificate of
     Incorporation or By-laws or other charter documents of BankAmerica, the
     Bank or Seafirst or any statute or any order, rule or regulation known to
     such counsel of any court or government agency or body having jurisdiction
     over BankAmerica, the Bank or Seafirst or any of their properties, in each
     case that is reasonably likely to have a material adverse effect on the
     Company and its subsidiaries, taken as a whole, or the validity,
     performance or consummation of the transactions contemplated by this
     Agreement and the International Underwriting Agreement;

              (iv) No notice, consent, approval, authorization, order,
     registration or qualification of or with any such court or governmental
     agency or body is required for the issue and sale of the Shares or the
     consummation by the Company of the transactions contemplated by this
     Agreement and the International Underwriting Agreement, except the
     registration under the Act of the Shares, and such notices, consents,
     approvals, authorizations, registrations or qualifications as may be
     required to be given to or received from (i) the Office of the Comptroller
     of the Currency and the Board of Governors of the Federal Reserve System
     that have been provided or obtained prior to the date hereof, (ii) foreign
     regulatory authorities in connection with the transfer of any part of BAMSA
     to the Company, and (iii) under state or foreign securities or Blue Sky
     laws in connection with the purchase and distribution of the Shares by the
     Underwriters and the International Underwriters; and

              (v) Although such counsel does not assume any responsibility for
     the accuracy, completeness or fairness of the statements contained in the
     Registration Statement or the Prospectus, nothing has come to the attention
     of such counsel to cause such counsel to believe that, as of its effective
     date, the Registration Statement or any further amendment thereto made by
     the Company prior to such Time of Delivery (other than the financial
     statements and related statements and related schedules therein or that
     should have been contained therein, as to which such counsel need express
     no opinion) contained an untrue statement of a material fact or omitted to
     state

                                      -14-
<PAGE>
 
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading or that, as of its date, the Prospectus
     or any further amendment or supplement thereto made by the Company prior to
     such Time of Delivery (other than the financial statements and related
     schedules therein or that should have been contained therein or that should
     have been contained therein, as to which such counsel need express no
     opinion) contained an untrue statement of a material fact or omitted to
     state a material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading or
     that, as of such Time of Delivery, either the Registration Statement or the
     Prospectus or any further amendment or supplement thereto made by the
     Company prior to such Time of Delivery (other than the financial statements
     and related schedules therein or that should have been contained therein,
     as to which such counsel need express no opinion) contains an untrue
     statement of a material fact or omits to state a material fact necessary to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading; and they do not know of any amendment to
     the Registration Statement required to be filed or of any contracts or
     other documents of a character required to be filed as an exhibit to the
     Registration Statement or required to be described in the Registration
     Statement or the Prospectus which are not filed or described as required;

             In rendering such opinion, such counsel may state that they express
     no opinion as to the laws of any jurisdiction outside the United States.

          (e) On the date of the Prospectus at a time prior to the execution of
     this Agreement, at 9:30 a.m., New York City time, on the effective date of
     any post-effective amendment to the Registration Statement filed subsequent
     to the date of this Agreement and also at each Time of Delivery, Ernst &
     Young LLP shall have furnished to you a letter or letters, dated the
     respective dates of delivery thereof, in form and substance satisfactory to
     you, to the effect set forth in Annex I hereto (the executed copy of the
     letter delivered prior to the execution of this Agreement is attached as
     Annex I(a) hereto and a draft of the form of letter to be delivered on the
     effective date of any post-effective amendment to the Registration
     Statement and as of each Time of Delivery is attached as Annex I(b)
     hereto);

          (f)(i)  Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included in the Prospectus any loss or interference with its business from
     fire, explosion, flood or other calamity, whether or not covered by
     insurance, or from any labor dispute or court or governmental action, order
     or decree, otherwise than as set forth or contemplated in the Prospectus,
     and (ii) since the respective dates as of which information is given in the
     Prospectus there shall not have been any change in the capital stock or
     long-term debt of the Company or any change, or any development involving a
     prospective change, in or affecting the general affairs, management,
     financial position, stockholders' equity or results of operations of the
     Company and its subsidiaries, otherwise than as set forth or contemplated
     in the Prospectus, the effect of which, in any such case described in
     Clause (i) or (ii), is in the judgment of the Representatives so material
     and adverse as to make it impracticable or inadvisable to proceed with the
     public offering or the delivery of the Shares being delivered at such Time
     of Delivery on the terms and in the manner contemplated in the Prospectus;

                                      -15-
<PAGE>
 
          (g) On or after the date hereof there shall not have occurred any of
     the following: (i) a suspension or material limitation in trading in
     securities generally on the New York Stock Exchange; (ii) a suspension or
     material limitation in trading in the Company's securities on the New York
     Stock Exchange; (iii) a general moratorium on commercial banking activities
     declared by either Federal or New York or California State authorities; or
     (iv) the outbreak or escalation of hostilities involving the United States
     or the declaration by the United States of a national emergency or war, if
     the effect of any such event specified in this Clause (iv) in the judgment
     of the Representatives makes it impracticable or inadvisable to proceed
     with the public offering or the delivery of the Shares being delivered at
     such Time of Delivery on the terms and in the manner contemplated in the
     Prospectus;

          (h) The Shares to be sold at such Time of Delivery shall have been
     duly listed subject to notice of issuance, on the New York Stock Exchange;

          (i)   The Company has obtained and delivered to the Underwriters
     executed copies of an agreement from each of BankAmerica, the Bank and
     Seafirst, substantially to the effect set forth in Subsection 6(e) hereof
     in form and substance satisfactory to you;

          (j)  The Company shall have complied with the provisions of Section
     6(c) hereof with respect to the furnishing of prospectuses on the New York
     Business Day next succeeding the date of this Agreement; and

          (k) The Company shall have furnished or caused to be furnished to you
     at such Time of Delivery certificates of the President and the Chief
     Financial Officer of the Company as to the accuracy of the representations
     and warranties of the Company herein at and as of such Time of Delivery, as
     to the performance by the Company of all of its obligations hereunder to be
     performed at or prior to such Time of Delivery, as to the matters set forth
     in subsections (a) and (f) of this Section (excluding, however, as to
     subsection (f), the reference to the judgment of the Representatives) and
     as to such other matters as you may reasonably request.

          9. (a)  The Company and BankAmerica will jointly and severally
     indemnify and hold harmless each Underwriter against any losses, claims,
     damages or liabilities, joint or several, to which such Underwriter may
     become subject, under the Act or otherwise, insofar as such losses, claims,
     damages or liabilities (or actions in respect thereof) arise out of or are
     based upon an untrue statement or alleged untrue statement of a material
     fact contained in any Preliminary Prospectus, the Registration Statement or
     the Prospectus, or any amendment or supplement thereto, or arise out of or
     are based upon the omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, and will reimburse each Underwriter for any legal
     or other expenses reasonably incurred by such Underwriter in connection
     with investigating or defending any such action or claim as such expenses
     are incurred; provided, however, that neither the Company nor BankAmerica
     shall be liable in any such case to the extent that any such loss, claim,
     damage or liability arises out of or is based upon an untrue statement or
     alleged untrue statement or omission or alleged omission made in any
     Preliminary Prospectus, the Registration Statement or the Prospectus or any
     such amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company or BankAmerica by or on behalf
     of any Underwriter through Goldman, Sachs & Co. expressly for use therein;
     and provided, further, that the Company shall not be liable to

                                      -16-
<PAGE>
 
     any Underwriter under the indemnity agreement in this subsection (a) with
     respect to any Preliminary Prospectus to the extent any such loss, claim
     damage or liability of such Underwriter results from the fact that such
     Underwriter sold Shares to a person as to whom it shall be established that
     there was not sent or given, at or prior to the written confirmation of
     such sale, a copy of the Prospectus or the Prospectus as then amended or
     supplemented in any case where such delivery is required by the Act if the
     Company has previously furnished copies thereof in sufficient quantity to
     such Underwriter and the loss, claim, damage or liability of such
     Underwriter results from an untrue statement of material fact or omission
     of a material fact contained in the Preliminary Prospectus which was
     corrected in the Prospectus or in the Prospectus as then amended or
     supplemented.

          (b) Each Underwriter will indemnify and hold harmless the Company and
     BankAmerica against any losses, claims, damages or liabilities to which the
     Company or BankAmerica may become subject, under the Act or otherwise,
     insofar as such losses, claims, damages or liabilities (or actions in
     respect thereof) arise out of or are based upon an untrue statement or
     alleged untrue statement of a material fact contained in any Preliminary
     Prospectus, the Registration Statement or the Prospectus, or any amendment
     or supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, in each
     case to the extent, but only to the extent, that such untrue statement or
     alleged untrue statement or omission or alleged omission was made in any
     Preliminary Prospectus, the Registration Statement or the Prospectus or any
     such amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company by or on behalf of such
     Underwriter through Goldman, Sachs & Co. expressly for use therein; and
     will reimburse the Company and BankAmerica for any legal or other expenses
     reasonably incurred by the Company or BankAmerica in connection with
     investigating or defending any such action or claim as such expenses are
     incurred.

          (c) Promptly after receipt by an indemnified party under subsection
     (a) or (b) above of notice of the commencement of any action, such
     indemnified party shall, if a claim in respect thereof is to be made
     against the indemnifying party under such subsection, notify the
     indemnifying party in writing of the commencement thereof; but the omission
     so to notify the indemnifying party shall not relieve it from any liability
     which it may have to any indemnified party otherwise than under such
     subsection.  In case any such action shall be brought against any
     indemnified party and it shall notify the indemnifying party of the
     commencement thereof, the indemnifying party shall be entitled to
     participate therein and, to the extent that it shall wish, jointly with any
     other indemnifying party similarly notified, to assume the defense thereof,
     with counsel satisfactory to such indemnified party (who shall not, except
     with the consent of the indemnified party, be counsel to the indemnifying
     party), and, after notice from the indemnifying party to such indemnified
     party of its election so to assume the defense thereof, (i) the
     indemnifying party shall not be liable to such indemnified party under such
     subsection for any legal expenses of other counsel or any other expenses,
     in each case subsequently incurred by such indemnified party, in connection
     with the defense thereof other than reasonable costs of investigation and
     (ii) the indemnified party agrees to cooperate with the indemnifying party
     in the defense of such action against such indemnified party except to the
     extent such cooperation would prejudice in any respect

                                      -17-
<PAGE>
 
     the rights of the indemnified party in such action or under this Section 9.
     The indemnifying party shall not be liable for any settlement of any action
     or claim effected without its written consent, which shall not be
     unreasonably withheld.

          (d) If the indemnification provided for in this Section 9 is
     unavailable to or insufficient to hold harmless an indemnified party under
     subsection (a) or (b) above in respect of any losses, claims, damages or
     liabilities (or actions in respect thereof) referred to therein, then each
     indemnifying party shall contribute to the amount paid or payable by such
     indemnified party as a result of such losses, claims, damages or
     liabilities (or actions in respect thereof) in such proportion as is
     appropriate to reflect the relative benefits received by the Company and
     BankAmerica on the one hand and the Underwriters on the other from the
     offering of the Shares.  If, however, the allocation provided by the
     immediately preceding sentence is not permitted by applicable law or if the
     indemnified party failed to give the notice required under subsection (c)
     above, then each indemnifying party shall contribute to such amount paid or
     payable by such indemnified party in such proportion as is appropriate to
     reflect not only such relative benefits but also the relative fault of the
     Company and BankAmerica on the one hand and the Underwriters on the other
     in connection with the statements or omissions which resulted in such
     losses, claims, damages or liabilities (or actions in respect thereof), as
     well as any other relevant equitable considerations.  The relative benefits
     received by the Company and BankAmerica on the one hand and the
     Underwriters on the other shall be deemed to be in the same proportion as
     the total net proceeds from the offering of the Shares purchased under this
     Agreement (before deducting expenses) received by the Company bear to the
     total underwriting discounts and commissions received by the Underwriters
     with respect to the Shares purchased under this Agreement, in each case as
     set forth in the table on the cover page of the Prospectus. The relative
     fault shall be determined by reference to, among other things, whether the
     untrue or alleged untrue statement of a material fact or the omission or
     alleged omission to state a material fact relates to information supplied
     by the Company or BankAmerica on the one hand or the Underwriters on the
     other and the parties' relative intent, knowledge, access to information
     and opportunity to correct or prevent such statement or omission.  The
     Company, BankAmerica and the Underwriters agree that it would not be just
     and equitable if contributions pursuant to this subsection (d) were
     determined by pro rata allocation (even if the Underwriters were treated as
     one entity for such purpose) or by any other method of allocation which
     does not take account of the equitable considerations referred to above in
     this subsection (d).  The amount paid or payable by an indemnified party as
     a result of the losses, claims, damages or liabilities (or actions in
     respect thereof) referred to above in this subsection (d) shall be deemed
     to include any legal or other expenses reasonably incurred by such
     indemnified party in connection with investigating or defending any such
     action or claim.  Notwithstanding the provisions of this subsection (d), no
     Underwriter shall be required to contribute any amount in excess of the
     amount by which the total price at which the Shares underwritten by it and
     distributed to the public were offered to the public exceeds the amount of
     any damages which such Underwriter has otherwise been required to pay by
     reason of such untrue or alleged untrue statement or omission or alleged
     omission.  No person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Act) shall be entitled to contribution from
     any person who was not guilty of such fraudulent misrepresentation.  The
     Underwriters' obligations in this subsection (d) to

                                      -18-
<PAGE>
 
     contribute are several in proportion to their respective underwriting
     obligations and not joint.

          (e) The obligations of the Company and BankAmerica under this Section
     9 shall be in addition to any liability which the Company or BankAmerica
     may otherwise have and shall extend, upon the same terms and conditions, to
     each person, if any, who controls any Underwriter within the meaning of the
     Act; and the obligations of the Underwriters under this Section 9 shall be
     in addition to any liability which the respective Underwriters may
     otherwise have and shall extend, upon the same terms and conditions, to
     each officer and director of the Company and BankAmerica and to each
     person, if any, who controls the Company or BankAmerica within the meaning
     of the Act.

          10.  (a)  If any Underwriter shall default in its obligation to
     purchase the Shares which it has agreed to purchase hereunder at a Time of
     Delivery, you may in your discretion arrange for you or another party or
     other parties to purchase such Shares on the terms contained herein.  If
     within thirty-six hours after such default by any Underwriter you do not
     arrange for the purchase of such Shares, then the Company shall be entitled
     to a further period of thirty-six hours within which to procure another
     party or other parties satisfactory to you to purchase such Shares on such
     terms.  In the event that, within the respective prescribed periods, you
     notify the Company that you have so arranged for the purchase of such
     Shares, or the Company notifies you that it has so arranged for the
     purchase of such Shares, you or the Company shall have the right to
     postpone such Time of Delivery for a period of not more than seven days, in
     order to effect whatever changes may thereby be made necessary in the
     Registration Statement or the Prospectus, or in any other documents or
     arrangements, and the Company agrees to file promptly any amendments to the
     Registration Statement or the Prospectus which in your opinion may thereby
     be made necessary.  The term "Underwriter" as used in this Agreement shall
     include any person substituted under this Section with like effect as if
     such person had originally been a party to this Agreement with respect to
     such Shares.

          (b) If, after giving effect to any arrangements for the purchase of
     the Shares of a defaulting Underwriter or Underwriters by you and the
     Company as provided in subsection (a) above, the aggregate number of such
     Shares which remains unpurchased does not exceed one-eleventh of the
     aggregate number of all the Shares to be purchased at such Time of
     Delivery, then the Company shall have the right to require each non-
     defaulting Underwriter to purchase the number of Shares which such
     Underwriter agreed to purchase hereunder at such Time of Delivery and, in
     addition, to require each non-defaulting Underwriter to purchase its pro
     rata share (based on the number of Shares which such Underwriter agreed to
     purchase hereunder) of the Shares of such defaulting Underwriter or
     Underwriters for which such arrangements have not been made; but nothing
     herein shall relieve a defaulting Underwriter from liability for its
     default.

          (c) If, after giving effect to any arrangements for the purchase of
     the Shares of a defaulting Underwriter or Underwriters by you and the
     Company as provided in subsection (a) above, the aggregate number of such
     Shares which remains unpurchased exceeds one-eleventh of the aggregate
     number of all the Shares to be purchased at such Time of Delivery, or if
     the Company shall not exercise the right

                                      -19-
<PAGE>
 
     described in subsection (b) above to require non-defaulting Underwriters to
     purchase Shares of a defaulting Underwriter or Underwriters, then this
     Agreement (or, with respect to the Second Time of Delivery, the obligations
     of the Underwriters to purchase and of the Company to sell the Optional
     Shares) shall thereupon terminate, without liability on the part of any
     non-defaulting Underwriter or the Company, except for the expenses to be
     borne by the Company and the Underwriters as provided in Section 7 hereof
     and the indemnity and contribution agreements in Section 9 hereof; but
     nothing herein shall relieve a defaulting Underwriter from liability for
     its default.

     11. The respective indemnities, agreements, representations, warranties and
other statements of the Company, BankAmerica and the several Underwriters, as
set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any Underwriter or any controlling person of any Underwriter, or the
Company or BankAmerica, or any officer or director or controlling person of the
Company or BankAmerica, and shall survive delivery of and payment for the
Shares.

     12. If this Agreement shall be terminated pursuant to Section 10 hereof,
the Company and BankAmerica shall not then be under any liability to any
Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other
reason, any Shares are not delivered by or on behalf of the Company as provided
herein, the Company will reimburse the Underwriters through you for all out-of-
pocket expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Underwriters in making preparations for the
purchase, sale and delivery of the Shares not so delivered, but the Company and
BankAmerica shall then be under no further liability to any Underwriter in
respect of the Shares not so delivered except as provided in Sections 7 and 9
hereof.

     13. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York  10004, Attention: Registration
Department; and if to the Company or BankAmerica shall be delivered or sent by
mail or facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by
mail or facsimile transmission to such Underwriter at its address set forth in
its Underwriters' Questionnaire, or telex constituting such Questionnaire, which
address will be supplied to the Company by you upon request.  Any such
statements, requests, notices or agreements shall take effect at the time of
receipt thereof.

     14. This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company, BankAmerica and, to the extent provided in
Sections 9 and 11 hereof, the officers and directors of the Company and
BankAmerica and each person who controls the Company, BankAmerica or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement.  No purchaser of any of the Shares from any
Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

                                      -20-

     15.  Time shall be of the essence of this Agreement.  As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     16. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK.

     17. This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts, each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us six counterparts hereof, and upon the acceptance hereof by you, on
behalf of each of the Underwriters, this letter and such acceptance hereof shall
constitute a binding agreement between each of the Underwriters, the Company and
BankAmerica.  It is understood that your acceptance of this letter on behalf of
each of the Underwriters is pursuant to the authority set forth in a form of
Agreement among Underwriters (U.S. Version), the form of which shall be

your part as to the authority of the signers thereof.

                                    Very truly yours,

                      FORM OF LETTER OF ERNST & YOUNG LLP
                    TO BE DELIVERED PURSUANT TO SECTION 8(D)

  Pursuant to Section 8(d) of the Underwriting Agreement, the accountants shall
furnish letters to the Underwriters to the effect that:

       (i) They are independent certified public accountants with respect to the
     Company and its subsidiaries within the meaning of the Act and the
     applicable published rules and regulations thereunder;

       (ii) In their opinion, the financial statements and any supplementary
     financial information and schedules (and, if applicable, financial
     forecasts and/or pro forma financial information) examined by them and
     included in the Prospectus or the Registration Statement comply as to form
     in all material respects with the applicable accounting requirements of the
     Act and the related published rules and regulations thereunder; and, if
     applicable, they have made a review in accordance with standards
     established by the American Institute of Certified Public Accountants of
     the unaudited consolidated interim financial statements, selected financial
     data, pro forma financial information, financial forecasts and/or condensed
     financial statements derived from audited financial statements of the
     Company for the periods specified in such letter, as indicated in their
     reports thereon, copies of which have been furnished separately to the
     representatives of the Underwriters (the "Representatives");

       (iii) They have made a review in accordance with standards established by
     the American Institute of Certified Public Accountants of the unaudited
     condensed consolidated statements of income, consolidated balance sheets
     and consolidated statements of cash flows included in the Prospectus as
     indicated in their reports thereon copies of which have been separately
     furnished to the Representatives and on the basis of specified procedures
     including inquiries of officials of the Company who have responsibility for
     financial and accounting matters regarding whether the unaudited condensed
     consolidated financial statements referred to in paragraph (vi)(A)(i) below
     comply as to form in all material respects with the applicable accounting
     requirements of the Act and the related published rules and regulations,
     nothing came to their attention that caused them to believe that the
     unaudited condensed consolidated financial statements do not comply as to
     form in all material respects with the applicable accounting requirements
     of the Act and the related published rules and regulations;

       (iv) The unaudited selected financial information with respect to the
     consolidated results of operations and financial position of the Company
     for the five most recent fiscal years included in the Prospectus agrees
     with the corresponding amounts (after restatements where applicable) in the
     audited consolidated financial statements for 1993, 1994 and 1995 and the
     unaudited consolidated financial statements for 1991 and 1992;

       (v) They have compared the information in the Prospectus under selected
     captions with the disclosure requirements of Regulation S-K and on the
     basis of limited procedures specified in such letter nothing came to their
     attention as a result of the foregoing procedures that caused them to
     believe that this information does not conform

     in all material respects with the disclosure requirements of Items 301,
     302, 402 and 503(d), respectively, of Regulation S-K;

       (vi) On the basis of limited procedures, not constituting an examination

     statements of the Company and its subsidiaries, inspection of the minute
     books of the Company and its subsidiaries since the date of the latest
     audited financial statements included in the Prospectus, inquiries of
     officials of the Company and its subsidiaries responsible for financial and
     accounting matters and such other inquiries and procedures as may be
     specified in such letter, nothing came to their attention that caused them
     to believe that:

             (A) (i) the unaudited consolidated statements of income,
          consolidated balance sheets and consolidated statements of cash flows
          included in the Prospectus do not comply as to form in all material
          respects with the applicable accounting requirements of the Act and
          the related published rules and regulations, or (ii) any material
          modifications should be made to the unaudited condensed consolidated
          statements of income, consolidated balance sheets and consolidated
          statements of cash flows included in the Prospectus for them to be in
          conformity with generally accepted accounting principles;

             (B) any other unaudited income statement data and balance sheet
          items included in the Prospectus do not agree with the corresponding
          items in the unaudited consolidated financial statements from which
          such data and items were derived, and any such unaudited data and
          items were not determined on a basis substantially consistent with the
          basis for the corresponding amounts in the audited consolidated
          financial statements included in the Prospectus;

             (C) the unaudited financial statements which were not included in
          the Prospectus but from which were derived any unaudited condensed
          financial statements referred to in Clause (A) and any unaudited
          income statement data and balance sheet items included in the
          Prospectus and referred to in Clause (B) were not determined on a
          basis substantially consistent with the basis for the audited
          consolidated financial statements included in the Prospectus;

             (D) any unaudited pro forma consolidated condensed financial
          statements included in the Prospectus do not comply as to form in all
          material respects with the applicable accounting requirements of the
          Act and the published rules and regulations thereunder or the pro
          forma adjustments have not been properly applied to the historical
          amounts in the compilation of those statements;

             (E) as of a specified date not more than five days prior to the
          date of such letter, there have been any changes in the consolidated
          capital stock (other than issuances of capital stock upon exercise of
          options and stock appreciation rights, upon earn-outs of performance
          shares and upon conversions of convertible securities, in each case
          which were outstanding on the date of the latest financial statements
          included in the Prospectus) or any increase in the consolidated long-
          term debt of the Company and its subsidiaries, or any

                                       2

          decreases in consolidated net current assets or stockholders' equity
          or other items specified by the Representatives, or any increases in
          any items specified by the Representatives, in each case as compared
          with amounts shown in the latest balance sheet included in the
          Prospectus, except in each case for changes, increases or decreases
          which the Prospectus discloses have occurred or may occur or which are
          described in such letter; and

             (F) for the period from the date of the latest financial statements
          included in the Prospectus to the specified date referred to in Clause
          (E) there were any decreases in consolidated net revenues or operating
          profit or the total or per share amounts of consolidated net income or
          other items specified by the Representatives, or any increases in any
          items specified by the Representatives, in each case as compared with
          the comparable period of the preceding year and with any other period
          of corresponding length specified by the Representatives, except in
          each case for decreases or increases which the Prospectus discloses
          have occurred or may occur or which are described in such letter; and

       (vii) In addition to the examination referred to in their report(s)
     included in the Prospectus and the limited procedures, inspection of minute
     books, inquiries and other procedures referred to in paragraphs (iii) and
     (vi) above, they have carried out certain specified procedures, not
     constituting an examination in accordance with generally accepted auditing
     standards, with respect to certain amounts, percentages and financial
     information specified by the Representatives, which are derived from the
     general accounting records of the Company and its subsidiaries, which
     appear in the Prospectus, or in Part II of, or in exhibits and schedules
     to, the Registration Statement specified by the Representatives, and have
     compared certain of such amounts, percentages and financial information
     with the accounting records of the Company and its subsidiaries and have
     found them to be in agreement.

     provisions of Section 242(b)(2) of the GCL or any corresponding provision
     hereinafter enacted.

          C.  The following is a statement of the powers, preferences, and

               1.  Except as otherwise set forth below in this ARTICLE FOURTH,
          the powers, preferences and relative participating, optional or other
          special rights and qualifications, limitations or restrictions of the
          Class A Common Stock and Class B Common Stock shall be identical in
          all respects.

               2.  Subject to the rights of the holders of Preferred Stock, and
          subject to any other provisions of this Amended and Restated
          Certificate of Incorporation, holders of Class A Common Stock and

          other distributions in cash, stock or property of the Corporation as
          may be declared thereon by the Board of Directors of the Corporation
          from time to time out of assets or funds of the Corporation legally
          available therefor. If any dividend or other distribution in cash or
          other property is paid with respect to Class A Common Stock or with
          respect to Class B Common Stock (other than dividends or other
          distributions payable in shares of Common Stock), a like dividend or
          other distribution in cash or other property shall also be paid with
          respect to shares of the other class of Common Stock, in an amount

                                      -2-
<PAGE>
 
          in number on a per share basis. Neither the shares of Class A Common
          Stock nor the shares of Class B Common Stock may be reclassified,
          subdivided or combined unless such reclassification, subdivision or
          combination occurs simultaneously and in the same proportion for each
          class.

               3.  (a)  At every meeting of the stockholders of the Corporation,
          every holder of Class A Common Stock shall be entitled to one vote in
          person or by proxy for each share of Class A Common Stock standing in
          his or her name on the transfer books of the Corporation, and every
          holder of Class B Common Stock shall be entitled to ten votes in
          person or by proxy for each share of Class B Common Stock standing in
          his or her name on the transfer books of the Corporation in connection
          with the election of directors and all other matters submitted to a
          vote of the stockholders; provided, however, that with respect to any
          proposed conversion subsequent to a Tax-Free Spin-Off (as defined in
          paragraph (C)(6)(b)(i) below) of the shares of Class B Common Stock
          into shares of Class A Common Stock pursuant to paragraph
          (C)(6)(b)(iii) below, each holder of a share of Common Stock,
          irrespective of class, shall have one vote in person or by proxy for
          each share of Common Stock standing in his or her name on the transfer
          books of the Corporation. Except as may be otherwise required by this
          ARTICLE FOURTH, the holders of Class A Common Stock and Class B Common
          Stock shall vote together as a single class, subject to any voting
          rights which may be granted to holders of Preferred Stock, on all
          matters submitted to a vote of the holders of Common Stock.

               (b)      Subject to any rights of the holders of Preferred Stock,
          the provisions of this Amended and Restated Certificate of
          Incorporation shall not be modified, revised, altered or amended,
          repealed or rescinded in whole or in part, without the approval of a
          majority of the votes entitled to be cast by the holders of the Class
          A Common Stock and the Class B Common Stock, voting together as a
          single class; provided, however, that with respect to any proposed
          amendment of this Amended and Restated Certificate of Incorporation
          which would alter or change the powers, preferences or special rights
          of the shares of Class A Common Stock or Class B Common Stock so as to
          affect them adversely, the approval of a majority of the votes
          entitled to be cast by the holders of the shares affected by the
          proposed amendment, voting separately as a class, shall be obtained in
          addition to the approval of a majority of the votes entitled to be
          cast by the holders of the

                                      -3-
<PAGE>
 
          Class A Common Stock and the Class B Common Stock voting together as a
          single class as hereinbefore provided. Any increase in the authorized
          number of shares of any class or classes of stock of the Corporation
          or creation, authorization or issuance of any securities convertible
          into, or warrants, options or similar rights to purchase, acquire or
          receive, shares of any such class or classes of stock shall be deemed
          not to affect adversely the powers, preferences or special rights of
          the shares of Class A Common Stock or Class B Common Stock. Neither
          the outcome of any vote with respect to any proposed conversion
          subsequent to a Tax-Free Spin-Off of the shares of Class B Common
          Stock into shares of Class A Common Stock pursuant to paragraph
          (C)(6)(b)(iii) below nor the occurrence of the events described in the
          last sentence of paragraph (C)(6)(b)(iii) below shall be deemed to be
          a modification, revision, alteration, amendment, repeal or rescission
          of the provisions of this Amended and Restated Certificate of
          Incorporation.

               (c)      Every reference in this Certificate of Incorporation to
          a majority or other proportion of shares of Common Stock, Class A
          Common Stock or Class B Common Stock shall refer to such majority or
          other proportion of the votes to which such shares of Common Stock,
          Class A Common Stock or Class B Common Stock, as applicable, are
          entitled.

               4.       In the event of any dissolution, liquidation or winding
          up of the affairs of the Corporation, whether voluntary or
          involuntary, after payment in full of the amounts required to be paid
          to the holders of Preferred Stock, the remaining assets and funds of
          the Corporation shall be distributed pro rata to the holders of Class
          A Common Stock and Class B Common Stock. For the purposes of this
          paragraph (C)(4), the voluntary sale, conveyance, lease, exchange or
          transfer (for cash, shares of stock, securities or other
          consideration) of all or substantially all of the assets of the
          Corporation or a consolidation or merger of the Corporation with one
          or more other corporations (whether or not the Corporation is the
          corporation surviving such consolidation or merger) shall not be
          deemed to be a liquidation, dissolution or winding up, voluntary or
          involuntary.

               5.       In the event of (i) any reorganization or any
          consolidation of the Corporation with one or more other corporations
          or a merger of the Corporation with another corporation unless (ii)
          immediately following such event, and

                                      -4-
<PAGE>
 
          based solely on the securities issued in connection therewith, a
          majority of the total voting power of the successor corporation is
          held by Persons that were stockholders of the Corporation immediately
          prior to such event, each holder of a share of Class A Common Stock
          shall be entitled to receive with respect to such share the same kind
          and amount of shares of stock and other securities and property
          (including cash) receivable upon such reorganization, consolidation or
          merger by a holder of a share of Class B Common Stock and each holder
          of a share of Class B Common Stock shall be entitled to receive with
          respect to such share the same kind and amount of shares of stock and
          other securities and property (including cash) receivable upon such
          reorganization, consolidation or merger by a holder of a share of
          Class A Common Stock.

               6.  (a)  Prior to the date on which shares of Class B Common
          Stock are distributed to stockholders of BankAmerica (as defined in
          paragraph (C)(6)(b)(i) below), or to stockholders of the Class B
          Transferee (as defined in paragraph (C)(6)(b)(ii) below) in a Tax-Free
          Spin-Off, each record holder of shares of Class B Common Stock may
          convert from time to time any or all of such shares into an equal
          number of shares of Class A Common Stock by surrendering the
          certificates for such shares, accompanied by any required tax transfer
          stamps and by a written notice by such record holder to the
          Corporation stating that such record holder desires to convert such
          shares of Class B Common Stock into the same number of shares of Class
          A Common Stock and requesting that the Corporation issue all of such
          shares of Class A Common Stock to Persons named therein, setting forth
          the number of shares of Class A Common Stock to be issued to each such
          Person and the denominations in which the certificates therefor are to
          be issued. To the extent permitted by law, such voluntary conversion
          shall be deemed to have been effected at the close of business on the
          date of such surrender. Following a Tax-Free Spin-Off, shares of Class
          B Common Stock shall no longer be convertible into shares of Class A
          Common Stock except as set forth in paragraph (C)(6)(b) below.

               (b)(i)   Prior to a Tax-Free Spin-Off, each share of Class B
          Common Stock shall automatically convert into one share of Class A
          Common Stock immediately prior to the transfer of such share if, after
          such transfer, such share is not Beneficially Owned (as defined below)
          by BankAmerica or, as set forth below in this paragraph (C)(6)(b), by
          a Class B Transferee or any subsidiary of a Class B Transferee. Shares

                                      -5-
<PAGE>
 
          of Class B Common Stock shall not convert into shares of Class A
          Common Stock (x) in any transfer effected in connection with a
          distribution of Class B Common Stock as a spin-off, split-up or split-
          off to stockholders of BankAmerica or stockholders of a Class B
          Transferee intended to be on a tax-free basis under the Internal
          Revenue Code of 1986, as amended from time to time (the "Code") (a
          "Tax-Free Spin-Off") or (y) except as otherwise set forth below in
          this paragraph (C)(6)(b), in any transfer after a Tax-Free Spin-Off.
          For purposes of this paragraph (C)(6), a Tax-Free Spin-Off shall be
          deemed to have occurred at the time shares are first transferred to
          stockholders of BankAmerica or stockholders of a Class B Transferee,
          as the case may be, following receipt of an affidavit described in
          clauses (vi) or (vii) of the first sentence of paragraph (C)(6)(d)
          below. For purposes of this paragraph (C)(6), "BankAmerica" shall mean
          BankAmerica Corporation, a Delaware corporation, all successors to
          BankAmerica Corporation by way of merger, consolidation or sale of all
          or substantially all its assets, and all corporations, partnerships,
          joint ventures, associations and other entities in which BankAmerica
          Corporation Beneficially Owns (as defined below), directly or
          indirectly, 50% or more of the voting power of the outstanding voting
          stock or similar voting interests ("Voting Interests") (each, a
          "Subsidiary Entity"), but which shall not include the Corporation or
          any Subsidiary Entity in which the Corporation Beneficially Owns (as
          defined below), directly or indirectly, 50% or more of the outstanding
          Voting Interest. For purposes of this paragraph (C)(6), the terms
          "Beneficially Own," "Beneficially Owns" and "Beneficially Owned" shall
          have the meanings ascribed to such terms in Rule 13d-3 of the General
          Rules and Regulations of the Securities Exchange Act of 1934, as in
          effect on October 11, 1996.

               (ii)     Prior to a Tax-Free Spin-Off, shares of Class B Common
          Stock representing more than a 50% economic interest in the then
          outstanding shares of Common Stock taken as a whole transferred in a
          single transaction to one Person who is not an affiliate of
          BankAmerica (a "Class B Transferee") or to a Class B Transferee and
          any Subsidiary Entity of such Class B Transferee, and shares of Class
          B Common Stock transferred among a Class B Transferee and any
          Subsidiary Entity thereof, shall not automatically convert to Class A
          Common Stock upon the transfer of such shares. Any shares of Class B
          Common Stock retained by BankAmerica (or, subject to the preceding
          sentence, a Class B Transferee) following any such transfer of shares
          of Class B Common

                                      -6-
<PAGE>
 
          Stock to a Class B Transferee (or subsequent Class B Transferee) shall
          automatically convert into shares of Class A Common Stock upon such
          transfer. For purposes of this paragraph (C)(6), the term "Person"
          shall mean any individual, firm, corporation or other entity; each
          reference to an "individual" (or to a "record holder" of shares, if an
          individual) shall be deemed to include in his or her representative
          capacity a guardian, committee, executor, administrator or other legal
          representative of such individual or record holder.

               (iii)    In the event of a Tax-Free Spin-Off, shares of Class B
          Common Stock shall automatically convert into shares of Class A Common
          Stock on the fifth anniversary of the date on which shares of Class B
          Common Stock are first transferred to stockholders of BankAmerica or
          the stockholders of a Class B Transferee, as the case may be, in a 
          Tax-Free Spin-Off unless, prior to such Tax-Free Spin-Off, BankAmerica
          or a Class B Transferee, as the case may be, delivers to the
          Corporation the written advice of counsel, reasonably satisfactory to
          the Corporation, to the effect that (x) such conversion could
          adversely affect the ability of BankAmerica or such Class B
          Transferee, as the case may be, to obtain a favorable ruling from the
          Internal Revenue Service that the distribution would be a Tax-Free
          Spin-Off under the Code or (y) the Internal Revenue Service has
          adopted a general non-ruling policy on tax-free spinoffs and that such
          conversion could adversely affect the status of the transaction as a
          Tax-Free Spinoff. If such written advice of counsel is received,
          approval of such conversion shall be submitted to a vote of the
          holders of the Common Stock as soon as practicable after the fifth
          anniversary of the Tax-Free Spin-Off. At the meeting of stockholders
          called for such purpose, every holder of Common Stock shall be
          entitled to one vote (irrespective of the voting rights provided for
          such shares under paragraph (C)(3)(a)) in person or by proxy for each
          share of Common Stock standing in his or her name on the transfer
          books of the Corporation. Approval of such conversion shall require
          the approval of a majority of the votes, on the per share voting basis
          provided in the preceding sentence, entitled to be cast by the holders
          of the Class A Common Stock and Class B Common Stock present and
          voting, voting together as a single class, and the holders of the
          Class B Common Stock shall not be entitled to a separate class vote.
          Such conversion shall be effective on the date on which such approval
          is given at a meeting of stockholders called for such purpose.
          Notwithstanding the foregoing, if BankAmerica or the Class B

                                      -7-
<PAGE>
 
          Transferee, as the case may be, delivers to the Corporation prior to
          such anniversary the written advice of counsel, reasonably
          satisfactory to the Corporation, to the effect that such vote could
          adversely affect the status of the transaction as a Tax-Free Spin-Off
          (including without limitation the ability to obtain a favorable ruling
          from the Internal Revenue Service) such vote shall not be held and no
          such conversion shall take place. Upon delivery of such written advice
          of counsel as to such vote, and the further advice that the continued
          existence of this paragraph (C)(6)(b)(iii) itself could adversely
          affect the status of the transaction as a Tax-Free Spin-Off (including
          without limitation the ability to obtain a favorable ruling from the
          Internal Revenue Service), then this paragraph (C)(6)(b)(iii) shall
          thereafter be null and void and no longer deemed to be part of this
          Amended and Restated Certificate of Incorporation.

               (iv)     If at any time prior to a Tax-Free Spin-Off BankAmerica
          or a Class B Transferee shall cease respectively to Beneficially Own a
          number of outstanding shares of Class B Common Stock at least equal to
          30% of the economic ownership represented by the aggregate number of
          shares of Common Stock then outstanding, then each share of Class B
          Common Stock Beneficially Owned by such less than 30% owner shall
          automatically convert into one share of Class A Common Stock.

               (v)      The Corporation will provide notice of any automatic
          conversion of all outstanding shares of Class B Common Stock to
          holders of record as soon as practicable after the conversion;
          provided, however, that the Corporation may satisfy such notice
          requirement by providing such notice prior to conversion. Such notice
          shall be provided by mailing notice of such conversion first class
          postage prepaid, to each holder of record of the Common Stock, at such
          holder's address as it appears on the transfer books of the
          Corporation; provided, however, that no failure to give such notice
          nor any defect therein shall affect the validity of the automatic
          conversion of any shares of Class B Common Stock. Each such notice
          shall state, as appropriate, the following:

               (w) the automatic conversion date;

               (x) that all outstanding shares of Class B Common Stock are
          automatically converted;

                                      -8-
<PAGE>
 
               (y) the place or places where certificates for such shares are to
          be surrendered for conversion; and

               (z) that no dividends will be declared on the shares of Class B
          Common Stock converted after such conversion date.

               Immediately upon such conversion, the rights of the holders of
          shares of Class B Common Stock as such shall cease and such holders
          shall be treated for all purposes as having become the record owners
          of the shares of Class A Common Stock issuable upon such conversion;
          provided, however, that such Persons shall be entitled to receive when
          paid any dividends declared on the Class B Common Stock as of a record
          date preceding the time of such conversion and unpaid as of the time
          of such conversion, subject to paragraph (C)(6)(f) below.

               (c)      Prior to a Tax-Free Spin-Off, holders of shares of Class
          B Common Stock may (i) sell or otherwise dispose of or transfer any or
          all of such shares held by them, respectively, only in connection with
          a transfer which meets the qualifications of paragraph (C)(6)(d)
          below, and under no other circumstances, or (ii) convert any or all of
          such shares into shares of Class A Common Stock as provided in
          paragraph (C)(6)(a) above. Prior to a Tax-Free Spin-Off, no one other
          than those Persons in whose names shares of Class B Common Stock
          originally are registered on the stock ledger of the Corporation, or
          transferees or successive transferees who receive shares of Class B
          Common Stock in connection with a transfer which meets the
          qualifications set forth in paragraph (C)(6)(d) below, shall by virtue
          of the acquisition of a certificate for shares of Class B Common Stock
          have the status of an owner or holder of shares of Class B Common
          Stock or be recognized as such by the Corporation or be otherwise
          entitled to enjoy for his or her own benefit the special rights and
          powers of a holder of shares of Class B Common Stock.

               Holders of shares of Class B Common Stock may at any and all
          times transfer to any Person the shares of Class A Common Stock
          issuable upon conversion of such shares of Class B Common Stock.

               (d)      Prior to a Tax-Free Spin-Off, shares of Class B Common
          Stock shall be transferred on the books of the Corporation and a new
          certificate therefor issued, upon presentation at the office of the
          Secretary of the Corporation

                                      -9-
<PAGE>
 
          (or at such additional place or places as may from time to time be
          designated by the Secretary of the Corporation) of the certificate for
          such shares, in proper form for transfer and accompanied by all
          requisite stock transfer tax stamps, only if such certificate when so
          presented shall also be accompanied by any one of the following:

               (i)   an affidavit from BankAmerica stating that such certificate
          is being presented to effect a transfer by BankAmerica of such shares
          to a Subsidiary Entity of BankAmerica; or

               (ii)  an affidavit from BankAmerica stating that such certificate
          is being presented to effect a transfer by any Subsidiary Entity of
          BankAmerica of such shares to BankAmerica or another Subsidiary Entity
          of BankAmerica; or

               (iii) an affidavit from BankAmerica (or a Class B Transferee)
          stating that such certificate is being presented to effect a transfer
          by BankAmerica (or such Class B Transferee) or any of its (or such
          Class B Transferee's) Subsidiary Entities of such shares to a Class B
          Transferee or a Subsidiary Entity of such Class B Transferee as
          contemplated by paragraph (C)(6)(b); or

               (iv)  an affidavit from a Class B Transferee stating that such
          certificate is being presented to effect a transfer by such Class B
          Transferee of such shares to a Subsidiary Entity of such Class B
          Transferee; or

               (v)   an affidavit from a Class B Transferee stating that such
          certificate is being presented to effect a transfer by any Subsidiary
          Entity of such Class B Transferee of such shares to such Class B
          Transferee or another Subsidiary Entity of such Class B Transferee; or

               (vi)  an affidavit from BankAmerica stating that such certificate
          is being presented to effect a transfer by BankAmerica of such shares
          to the stockholders of BankAmerica in connection with a Tax-Free Spin-
          Off; or

               (vii) an affidavit from a Class B Transferee stating that such
          certificate is being presented to effect a transfer by such Class B
          Transferee of such shares to the stockholders of such Class B
          Transferee in connection with a Tax-Free Spin-Off.

               Each affidavit of a record holder furnished pursuant to this
          paragraph (C)(6)(d) shall be verified as of a date not earlier than
          five days prior to the date of delivery thereof, and, where such
          record holder is a corporation or partnership, shall be verified by an
          officer of the corporation or by a general partner of the partnership,
          as the case may be.

               (e) Prior to the occurrence of a Tax-Free Spin-Off, each
          certificate for shares of Class B Common Stock shall bear a legend on
          the face thereof reading as follows:

               "The shares of Class B Common Stock represented by this
          certificate may not be transferred to any person or entity in
          connection with a transfer that does not meet the qualifications set
          forth in paragraph (C)(6)(d) of ARTICLE FOURTH of the Certificate of
          Incorporation of this Corporation and no person who receives such
          shares in connection with a transfer which does not meet the
          qualifications prescribed by paragraph (C)(6)(d) of said ARTICLE
          FOURTH is entitled to own or to be registered as the record holder of
          such shares of Class B Common Stock and such shares will have been
          automatically converted into Class A Common Stock upon any such
          purported transfer.  The record holder of this certificate may at any
          time convert such shares of Class B Common Stock into the same number
          of shares of Class A Common Stock.  Each holder of this certificate,
          by accepting the same, accepts and agrees to all of the foregoing."

               Upon and after the transfer of shares in a Tax-Free Spin-Off,
          shares of Class B Common Stock shall no longer bear the legend set
          forth above in this paragraph (C)(6)(e).

               (f) Upon any conversion of shares of Class B Common Stock into
          shares of Class A Common Stock pursuant to the provisions of this
          paragraph (C)(6), any dividend, for which the payment date shall be
          subsequent to such conversion, which may have been declared on the
          shares of Class B Common Stock so converted shall be deemed to have
          been declared, and shall be payable, with respect to the shares of
          Class A Common Stock into or for which such shares of Class B Common
          Stock shall have been so converted, and any such dividend payable in
          Common Stock shall be deemed to have been declared, and shall be
          payable, in shares of Class A Common Stock.

                                      -11-

               (g)      The Corporation shall not reissue or resell any shares
          of Class B Common Stock which shall have been converted into shares of
          Class A Common Stock pursuant to or as permitted by the provisions of
          this paragraph (C)(6), or any shares of Class B Common Stock which
          shall have been acquired by the Corporation in any other manner. The
          Corporation shall, from time to time, take such appropriate action as
          may be necessary to retire such shares and to reduce the authorized
          amount of Class B Common Stock accordingly.

               The Corporation shall at all times reserve and keep available,
          out of its authorized but unissued Common Stock, such number of shares
          of Class A Common Stock as would become issuable upon the conversion
          of all shares of Class B Common Stock then outstanding.

               (h)      In connection with any transfer or conversion of any
          stock of the Corporation pursuant to or as permitted by the provisions
          of this paragraph (C)(6) or in connection with the making of any
          determination referred to in this paragraph (C)(6):

               (1)  the Corporation shall be under no obligation to make any
          investigation of facts unless an officer, employee or agent of the
          Corporation responsible for making such transfer or determination or
          issuing Class A Common Stock pursuant to such conversion has
          substantial reason to believe, or unless the Board of Directors (or a
          committee of the Board of Directors designated for such purpose)
          determines that there is substantial reason to believe, that any
          affidavit or other document is incomplete or incorrect in a material
          respect or that an investigation would disclose facts upon which any
          determination referred to in paragraph (C)(6)(f) above should be made,
          in either of which events the Corporation shall make or cause to be
          made such investigation as it may deem necessary or desirable in the
          circumstances and have a reasonable time to complete such
          investigation; and

               (2)  neither the Corporation nor any director, officer, employee
          or agent of the Corporation shall be liable in any manner for any
          action taken or omitted in good faith.

               (i) The Corporation will not be required to pay any documentary,
          stamp or similar issue or transfer taxes payable in respect of the
          issue or delivery of shares of Class A Common Stock on the conversion
          of shares of Class B Common Stock

                                      -12-
<PAGE>
 
          pursuant to this paragraph (C)(6), and no such issue or delivery shall
          be made unless and until the Person requesting such issue has paid to
          the Corporation the amount of any such tax or has established, to the
          satisfaction of the Corporation, that such tax has been paid.

               7.       All rights to vote and all voting power (including,
          without limitation thereto, the right to elect directors) shall be
          vested exclusively in the holders of Common Stock, voting together as
          a single class, except as otherwise expressly provided in this Amended
          and Restated Certificate of Incorporation, in a Preferred Stock
          Designation or as otherwise expressly required by applicable law.

          D.   Subject to the limitations and in the manner provided by law,
     shares of the Preferred Stock may be issued from time to time in series,
     and the Board of Directors of the Corporation or a duly-authorized
     committee of the Board of Directors of the Corporation, in accordance with
     the laws of the State of Delaware, is hereby authorized to determine or
     alter the relative rights, powers (including voting powers), preferences,
     privileges and restrictions granted to or imposed upon Preferred Stock or
     any wholly unissued series of shares of Preferred Stock, and to increase or
     decrease (but not below the number of shares of any series of Preferred
     Stock then outstanding) the number of shares of any such series subsequent
     to the issue of shares of that series. In case the number of shares of any
     series shall be so decreased, the shares constituting such decrease shall
     upon the taking of any action required by applicable law resume the status
     which they had prior to the adoption of the resolution originally fixing
     the number of shares of such series.

     V.  FIFTH:  In accordance with Section 203(b)(3) of the GCL, the
         -----                                                       
     Corporation expressly elects not to be governed by Section 203 of the GCL.

     VI.  SIXTH:  The books and records of the Corporation may be kept (subject
          -----                                                                
     to any mandatory requirement of law) outside the State of Delaware at such
     place or places as may be designated from time to time by the Board of
     Directors or by the Bylaws of the Corporation.

     VII.  SEVENTH:  Special meetings of stockholders of the Corporation, for
           -------                                                           
     any purpose or purposes, unless otherwise prescribed by statute or by this
     Amended and Restated Certificate of Incorporation, may be called by the
     Chairman of the Board or the President and shall be called by the Chairman
     of the Board or the President or Secretary at the request in writing of a
     majority of the Board of Directors, or at the request in writing of
     stockholders owning a majority in amount of the total voting power of the
     entire capital

                                      -13-
<PAGE>
 
     stock of the Corporation issued and outstanding and entitled to vote.  Such
     request shall state the purpose or purposes of the proposed meeting.

          EIGHTH:  In furtherance and not in limitation of the powers conferred
          ------                                                               
     upon it by the laws of the State of Delaware, the Board of Directors shall
     have the power to adopt, amend, alter or repeal the Corporation's Bylaws.

          NINTH:  No director of the Corporation shall be liable to the
          -----                                                        
     Corporation or its stockholders for monetary damages for breach of
     fiduciary duty as a director, except for liability (i) for any breach of
     the director's duty of loyalty to the Corporation or its stockholders, (ii)
     for acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law, (iii) under Section 174 of the
     GCL, or (iv) for any transaction from which the director derived an
     improper personal benefit.

          If the GCL hereafter is amended to further eliminate or limit the
     liability of directors, then the liability of a director of the
     Corporation, in addition to the limitation on personal liability provided
     herein, shall be limited to the fullest extent permitted by the amended
     GCL. Any repeal or modification of this paragraph by the stockholders of
     the Corporation shall be prospective only, and shall not adversely affect
     any limitation on the personal liability of a director of the Corporation
     existing at the time of such repeal or modification.

     IN WITNESS WHEREOF, this Amended and Restated Certificate of Incorporation
has been signed by Cheryl Sorokin, its authorized officer this 29th day of
November, 1996.

          -----------------------------------                                  
to file a registration statement under the Securities Act in connection with a
proposed offer and sale for cash of any equity securities (other than an

holders of its outstanding equity securities, BAMSI will give prompt written
notice of its determination to each Holder and of such Holder's rights under
this Section 2, at least 30 days prior to the anticipated filing date of such
registration statement.  Upon the written request of each Holder made within 21
days after the receipt of any such notice from BAMSI, (which request shall
specify the Registrable Shares intended to be disposed of by such Holder), BAMSI
will use its best efforts to effect the registration under the Securities Act of
all Registrable Shares which BAMSI has been so requested to register by the
Holders thereof, to the extent required to permit the disposition of the
Registrable

                                     -3-          Registration Rights Agreement
<PAGE>
 
Shares so to be registered; provided, however, that (i) if, at any time after
                            --------  -------                                
giving written notice of its intention to register any securities and prior to
the effective date of the registration statement filed in connection with such
registration, BAMSI shall determine for any reason not to proceed with the
proposed registration of the securities to be sold by it, BAMSI may, at its
election, give written notice of such determination to each Holder of
Registrable Shares and thereupon shall be relieved of its obligation to register
any Registrable Shares in connection with such registration (but not from its
obligation to pay the Registration Expenses in connection therewith), and (ii)
if such registration involves an underwritten offering, all Holders of
Registrable Shares requesting to be included in BAMSI's registration must sell
their Registrable Shares to the underwriters on the same terms and conditions as
apply to BAMSI, with such differences, including any with respect to
indemnification and liability insurance, as may be customary or appropriate in
combined primary and secondary offerings.  If a registration requested pursuant
to this Section 2 involves an underwritten public offering, any Holder of
Registrable Shares requesting to be included in such registration may elect, in
writing prior to the effective date of the registration statement filed in
connection with such registration, not to register such securities in connection
with such registration.  No registration effected under this Section 2 shall
relieve BAMSI of its obligations to effect registrations upon request under
Section 4 hereof.

     (b)  Priority in Incidental Registration.  If a registration pursuant to
          -----------------------------------                                
this Section 2 involves an underwritten offering and the managing
underwriter(s) in good faith advise(s) BAMSI in writing that, in its opinion,
the number of securities which BAMSI, the Holders and any other Persons intend
to include in such registration exceeds the largest number of securities which
can be sold in such offering without having an adverse effect on such offering
(including the price at which such securities can be sold), then BAMSI will
include in such registration (i) first, if the registration pursuant to this
Section 2 was initiated by Other Holders exercising demand registration rights,
100% of the securities such Other Holders propose to sell (except to the extent
the terms of such Other Holders' registration rights provide otherwise); (ii)
second, 100% of the securities BAMSI proposes to sell for its own account; (iii)
third, to the extent that the number of securities which such Other Holders
exercising demand registration rights and BAMSI propose to sell is less than the
number of securities which BAMSI has been advised can be sold in such offering
without having the adverse effect referred to above, such number of Registrable
Shares which the Holders have requested to be included in such registration
pursuant to Section 2(a) hereof and which, in the opinion of such managing
underwriter(s), can be sold without having the adverse effect referred to above;
and (iv) fourth, to the extent that the number of securities which are to be
included in such registration pursuant to clauses (i), (ii) and (iii) is, in the
aggregate, less than the number of securities which BAMSI has been advised can
be sold in such offering without having the adverse effect referred to above,
such number of other securities requested to be included in the offering for the
account of any Other Holders which, in the opinion of such managing
underwriter(s), can be sold without having the adverse effect referred to above.

     3.   Holdback Agreements.
          ------------------- 

     (a)  If any registration of Registrable Shares shall be in connection with
an underwritten public offering, the Holders shall not effect any public sale or
distribution (except in connection with such public offering), of any equity
securities of BAMSI, or of any security convertible into or exchangeable or
exercisable for any equity security of BAMSI (in each case, other than as part
of such underwritten public offering), during the 90-day period (or such lesser
period as the managing underwriter(s) beginning on the effective date of such
registration, if, and to the extent, the managing underwriter(s) of any such
offering determine(s) such action is necessary or desirable to effect such
offering; provided, however, that each Holder has received the written notice
          --------  -------                                                  
required by Section 2(a) hereof; provided, however, that each Holder shall not
                                 --------  -------                            
be obligated to comply with such restrictions arising as a result of an
underwritten public offering subject to Section 2 hereof more than once in any
12-month period.

     (b)  If any registration of Registrable Shares shall be in connection with
any underwritten public offering, BAMSI shall not effect any public sale or
distribution (except in connection with such public offering) of any of its
equity securities or of any security convertible into or exchangeable or
exercisable for any of its equity securities (in each case other than as part of
such underwritten public offering) during the 180-day period (or such lesser
period as the managing underwriter(s) may permit) beginning on the effective
date of such registration, and BAMSI shall use its best efforts to cause each
member of the management of BAMSI who holds any equity security and each other
holder of 5% or more of the outstanding shares of any equity security, or of any
security convertible into or exchangeable or exercisable for any equity
security, of BAMSI purchased from BAMSI (at any time other than in a public
offering) to so agree.

     4.   Registration on Request.
          ----------------------- 

     (a)  Request by Holders.  Upon the written request of the Holders of at
          ------------------                                                
least 10% of the Registrable Shares (calculated on the based on the number in
clause (i) of its definition) that BAMSI effect the registration under the
Securities Act of all or part of such Holders' Registrable Shares, and
specifying the amount (which shall not be less than 10% of the Registrable
Shares (calculated on the based on the number in clause (i) of its definition)
in the aggregate) and the intended method of disposition thereof, BAMSI will
promptly give notice of such requested registration to all other Holders of
Registrable Shares and, as expeditiously as possible, use its best efforts to
effect the registration under the Securities Act of: (i) the Registrable Shares
which BAMSI has been so requested to register by Holders of at least 10% of the
Registrable Shares; and (ii) all other Registrable Shares which BAMSI has been
requested to register by any other Holder thereof by written request received by
BAMSI within 21 days after the giving of such written notice by BAMSI (which
request shall specify the intended method of disposition of such Registrable
Shares); provided, however, that BAMSI shall not be required to effect more than
         --------  -------                                                      
two registrations pursuant to this Section 4; provided, further, that BAMSI
                                              --------  -------            
shall not be obligated to file a registration statement relating to a
registration request under this Section 4 (x) if the registration request is
delivered after delivery of a notice by BAMSI of an intended


                                     -5-          Registration Rights Agreement
<PAGE>
 
registration and prior to the effective date of the registration statement
referred to in such notice, or (y) within a period of 90 days after the
effective date of any other registration statement of BAMSI requested by a
Holder pursuant to this Section 4 or pursuant to which the Holders included
Registrable Shares.  The Holders initially requesting a registration pursuant to
this Section 4 may, at any time prior to the effective date of the registration
statement relating to such registration, revoke such request by providing a
written notice to BAMSI revoking such request; provided, however, that, in the
                                               --------  -------              
event the Holders shall have made a written request for a demand registration
(I) which is subsequently withdrawn by the Holders after BAMSI has filed a
registration statement with the SEC in connection therewith but prior to such
demand registration being declared effective by the SEC or (II) which is not
declared effective solely as a result of the failure of Holders to take all
actions reasonably required in order to have the registration and the related
registration statement declared effective by the SEC, then, in any such event,
such demand registration shall be counted as a demand registration for purposes
of this Section 4(a).  Promptly after the expiration of the 21-day period
referred to in clause (ii) above, BAMSI will notify all the Holders to be
included in the registration of the other Holders and the number of shares of
Registrable Shares requested to be included therein.

     (b)  Registration Statement Form.  If any registration requested pursuant
          ---------------------------
to this Section 4 which is proposed by BAMSI to be effected by the filing of a
registration statement on Form S-3 (or any successor or similar short-form
registration statement) shall be in connection with an underwritten public
offering, and if the managing underwriter(s) shall advise BAMSI in writing that,
in its opinion, the use of another form of registration statement is of material
importance to the success of such proposed offering, then such registration
shall be effected on such other form.

     (c)  Effective Registration Statement.  A registration requested pursuant
          --------------------------------
to this Section 4 will not be deemed to have been effected unless it has become
effective under the Securities Act and has remained effective for 270 days or
such shorter period as all the Registrable Shares included in such registration
have actually been sold thereunder. In addition, if within 180 days after it has
become effective, the offering of Registrable Shares pursuant to such
registration is interfered with by any stop order, injunction or other order or
requirement of the SEC or other governmental agency or court, such registration
will be deemed not to have been effected for purposes of this Section 4.

     (d)  Priority in Requested Registrations.  If a requested registration
          -----------------------------------                              
pursuant to this Section 4 involves an underwritten offering and the managing
underwriter(s) in good faith advise(s) BAMSI in writing that, in its opinion,
the number of securities requested to be included in such registration
(including securities of BAMSI which are not Registrable Shares) exceeds the
largest number of securities which can be sold in such offering without having
an adverse effect on such offering (including the price at which such securities
can be sold), then BAMSI will include in such registration (i) first, 100% of
the Registrable Shares requested to be registered pursuant to Section 4(a)
hereof (provided that if the number of Registrable Shares requested to be
registered pursuant to Section 4(a) hereof exceeds the number which BAMSI has
been advised can be sold in such offering without having the adverse effect
referred to above, the number of such Registrable Shares to be


                                     -6-          Registration Rights Agreement
<PAGE>
 
included in such registration by the Holders shall be allocated pro rata among
such Holders on the basis of the relative number of Registrable Shares each such
Holder has requested to be included in such registration); (ii) second, to the
extent that the number of Registrable Shares requested to be registered pursuant
to Section 4(a) hereof is less than the number of securities which BAMSI has
been advised can be sold in such offering without having the adverse effect
referred to above, such number of shares of equity securities BAMSI requests to
be included in such registration, and (iii) third, to the extent that the number
of Registrable Shares requested to be included in such registration pursuant to
Section 4(a) hereof and the securities which BAMSI proposes to sell for its own
account are, in the aggregate, less than the number of equity securities which
BAMSI has been advised can be sold in such offering without having the adverse
effect referred to above, such number of other securities proposed to be sold by
any Other Holder which, in the opinion of such managing underwriter(s), can be
sold without having the adverse effect referred to above (provided that if the
number of such securities of such Other Holder requested to be registered
exceeds the number which BAMSI has been advised can be sold in such offering
without having the adverse effect referred to above, the number of such
securities to be included in such registration pursuant to this Section 4(d)
shall be allocated pro rata among all such Other Holders on the basis of the
relative number of securities each such Other Holder has requested to be
included in such registration).

     (e)  Additional Rights.  If BAMSI at any time grants to any other holders
          -----------------
of equity securities of BAMSI any rights to request BAMSI to effect the
registration of any such shares of equity securities on terms more favorable to
such holders than the terms set forth in this Section 4 and in Section 5 hereof,
the terms of this Section 4 and of Section 5 hereof shall be deemed amended or
supplemented to the extent necessary to provide the Holders such more favorable
rights and benefits. In no event shall BAMSI grant to any person any rights to
request BAMSI to effect the registration of any shares of equity securities of
BAMSI on terms which are adverse to rights of the Holders set forth in Section 2
and this Section 4.

     5.   Registration Procedures.
          ----------------------- 

     (a)  If and whenever BAMSI is required by the provisions of Section 2 or 4
hereof to use its best efforts to effect or cause the registration of
Registrable Shares, BAMSI shall as expeditiously as possible:

          (i)  prepare and, in any event within 60 days after the end of the
     period within which a request for registration may be given to BAMSI, file
     with the SEC a registration statement with respect to such Registrable
     Shares and use its best efforts to cause such registration statement to
     become effective;

          (ii)  prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection therewith
     as may be necessary to keep such registration statement effective for a
     period not in excess of 270 days and to comply with the provisions of the
     Securities


                                     -7-          Registration Rights Agreement
<PAGE>
 
     Act, the Exchange Act, and the rules and regulations promulgated thereunder
     with respect to the disposition of all the securities covered by such
     registration statement during such period in accordance with the intended
     methods of disposition by the Holders thereof set forth in such
     registration statement; provided, however, that (A) before filing a
                             --------  -------                          
     registration statement (including an initial filing) or prospectus, or any
     amendments or supplements thereto, BAMSI will furnish to one counsel
     selected by the Holders of a majority of the Registrable Shares covered by
     such registration statement copies of all documents proposed to be filed,
     which documents will be subject to the review and comment of such counsel,
     and (B) BAMSI will notify each Holder of Registrable Shares covered by such
     registration statement of any stop order issued or threatened by the SEC,
     any other order suspending the use of any preliminary prospectus or of the
     suspension of the qualification of the registration statement for offering
     or sale in any jurisdiction, and take all reasonable actions required to
     prevent the entry of such stop order, other order or suspension or to
     remove it if entered;

          (iii)  furnish to each Holder and each underwriter, if applicable, of
     Registrable Shares covered by such registration statement such number of
     copies of the registration statement and of each amendment and supplement
     thereto (in each case including all exhibits), such number of copies of the
     prospectus included in such registration statement (including each
     preliminary prospectus and summary prospectus), in conformity with the
     requirements of the Securities Act, and such other documents as each Holder
     of Registrable Shares covered by such registration statement may reasonably
     request in order to facilitate the disposition of the Registrable Shares by
     such Holder;

          (iv)  use its best efforts to register or qualify such Registrable
     Shares covered by such registration statement under the state securities or
     blue sky laws of such jurisdictions as each Holder of Registrable Shares
     covered by such registration statement and, if applicable, each
     underwriter, may reasonably request, and do any and all other acts and
     things which may be reasonably necessary to consummate the disposition in
     such jurisdictions of the Registrable Shares owned by such Holder, except
     that BAMSI shall not for any purpose be required to qualify generally to do
     business as a foreign corporation in any jurisdiction where, but for the
     requirements of this clause (iv), it would not be obligated to be so
     qualified;

          (v)  use its best efforts to cause such Registrable Shares covered by
     such registration statement to be registered with or approved by such other
     governmental agencies or authorities as may be necessary to enable the
     Holders thereof to consummate the disposition of such Registrable Shares;

          (vi)  if at any time when a prospectus relating to the Registrable
     Shares is required to be delivered under the Securities Act, any event
     shall have occurred as the result of which any such prospectus as then in
     effect


                                     -8-          Registration Rights Agreement
<PAGE>
 
     would include an untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, immediately give written notice thereof
     to each Holder and the managing underwriter or underwriters, if any, of
     such Registrable Shares and prepare and furnish to each such Holder a
     reasonable number of copies of an amended or supplemental prospectus as may
     be necessary so that, as thereafter delivered to the purchasers of such
     Registrable Shares, such prospectus shall not include an untrue statement
     of material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading;

          (vii)  use its best efforts to list any portion of such Registrable
     Shares not already listed on any securities exchange on which similar
     securities of BAMSI are then listed, and enter into customary agreements
     including a listing application and indemnification agreement in customary
     form, provided that the applicable listing requirements are satisfied, and
     provide a transfer agent and registrar for such Registrable Shares covered
     by such registration statement not later than the effective date of such
     registration statement;

          (viii)  enter into such customary agreements (including an
     underwriting agreement in customary form) and take such other actions as
     each Holder of Registrable Shares being sold or the underwriter or
     underwriters, if any, reasonably request in order to expedite or facilitate
     the disposition of such Registrable Shares, including customary
     indemnification and opinions;

          (ix)  use its best efforts to obtain a "cold comfort" letter or
     letters from BAMSI's independent public accountants in customary form and
     covering matters of the type customarily covered by "cold comfort" letters
     as the Holders of the Registrable Shares being sold or the underwriters
     retained by such Holders shall reasonably request;

          (x)  make available for inspection by representatives of any Holder of
     Registrable Shares covered by such registration statement, by any
     underwriter participating in any disposition to be effected pursuant to
     such registration statement and by any attorney, accountant or other agent
     retained by such Holders or any such underwriter, all financial and other
     records pertinent corporate documents and properties of BAMSI and its
     subsidiaries' officers, directors and employees to supply all information
     and respond to all inquiries reasonably requested by such Holders or any
     such representative, underwriter, attorney, accountant or agent in
     connection with such registration statement;

          (xi)  promptly prior to the filing of any document which is to be
     incorporated by reference into the registration statement or the prospectus
     (after initial filing of the registration statement), provide copies of
     such document to counsel to the Holders of Registrable Shares covered by
     such


                                     -9-           Registration Rights Agreement
<PAGE>
 
     registration statement and to the managing underwriter(s), if any, make
     BAMSI's representatives available for discussion of such document and make
     such changes in such document prior to the filing thereof as counsel for
     such Holders or underwriter(s) may reasonably request;

          (xii)  otherwise use its best efforts to comply with all applicable
     rules and regulations of the SEC, and make available to its security
     holders, as soon as reasonably practicable after the effective date of the
     registration statement, an earning statement which shall satisfy the
     provisions of Section 11(a) of the Securities Act and the rules and
     regulations promulgated thereunder;

          (xiii)  not later than the effective date of the applicable
     registration statement, use its best efforts to provide a CUSIP number for
     any portion of such Registrable Shares not already included in a CUSIP
     number for similar securities of BAMSI, and provide the applicable transfer
     agents with printed certificates for the Registrable Shares which are in a
     form eligible for deposit with the Depository Trust Company;

          (xiv)  notify counsel for the Holders of Registrable Shares included
     in such registration statement and the managing underwriter or
     underwriters, if any, immediately and confirm the notice in writing, (A)
     when the registration statement, or any post-effective amendment to the
     registration statement, shall have become effective, or any supplement or
     amendment to the prospectus shall have been filed, (B) of the receipt of
     any comments from the SEC and (C) of any request of the SEC to amend the
     registration statement or amend or supplement the prospectus or for
     additional information; and

          (xv)  cooperate with each seller of Registrable Shares and each
     underwriter, if any, participating in the disposition of such Registrable
     Shares and their respective counsel in connection with any filings required
     to be made with the NASD.

     (b)  Each Holder of Registrable Shares hereby agrees that, upon receipt of
any notice from BAMSI of the happening of any event of the type described in
Section 5(a)(vi) hereof, such Holder shall forthwith discontinue disposition of
such Registrable Shares covered by such registration statement or related
prospectus until such Holder's receipt of the copies of the supplemental or
amended prospectus contemplated by Section 5(a)(vi) hereof, and, if so directed
by BAMSI, such Holder will deliver to BAMSI (at BAMSI's expense) all copies,
other than permanent file copies then in such Holder's possession, of the
prospectus covering such Registrable Shares at the time of receipt of such
notice.  In the event BAMSI shall give any such notice, the period mentioned in
Section 5(a)(ii) hereof shall be extended by the number of days during the
period from and including the date of the giving of such notice pursuant to
Section 5(a)(vi) hereof and including the date when such Holder shall have
received the copies of the supplemental or amended prospectus contemplated by
Section 5(a)(vi) hereof.  If for any other reason the


                                     -10-          Registration Rights Agreement
<PAGE>
 
effectiveness of any registration statement filed pursuant to Section 4 hereof
is suspended or interrupted prior to the expiration of the time period regarding
the maintenance of the effectiveness of such Registration Statement required by
Section 5(a)(ii) hereof so that Registrable Shares may not be sold pursuant
thereto, the applicable time period shall be extended by the number of days
equal to the number of days during the period beginning with the date of such
suspension or interruption to and ending with the date when the sale of
Registrable Shares pursuant to such registration statement may be recommenced.

     (c)  Each Holder hereby agrees to provide BAMSI, upon receipt of its
request, with such information about such Holder to enable BAMSI to comply with
the requirements of the Securities Act and to execute such certificates as BAMSI
may reasonably request in connection with such information and otherwise to
satisfy any requirements of law.

     6.   Underwritten Registrations.  Subject to the provisions of Sections 2,
          --------------------------                                           
3 and 4 hereof, any of the Registrable Shares covered by a registration
statement may be sold in an underwritten offering at the discretion of the
Holder thereof.  In the case of an underwritten offering pursuant to Section 2
hereof, the managing underwriter(s) that will administer the offering shall be
selected by BAMSI; provided, however, that such managing underwriter(s) shall be
                   --------  -------                                            
reasonably satisfactory to the Holders of a majority of the Registrable Shares
to be registered.  In the case of any underwritten offering pursuant to Section
4 hereof, the managing underwriter(s) that will administer the offering shall be
selected by the Holders of a majority of the Registrable Shares to be

            --------  -------                                              
satisfactory to BAMSI.

     8.   Indemnification.
          --------------- 

     (a)  Indemnification by BAMSI.  In the event of any registration of any
          ------------------------                                          
securities of BAMSI under the Securities Act pursuant to Section 2 or 4 hereof,
BAMSI will, and it hereby does, indemnify and hold harmless, to the extent
permitted by law, each of the Holders of any Registrable Shares covered by such
registration statement, each Affiliate of such Holder (other than BAMSI) and
their respective directors and officers, each other Person who participates as
an underwriter in the offering or sale of such securities and each other Person,
if any, who controls such Holder or any such underwriter within the meaning of
the Securities Act (collectively, the "Indemnified Parties"), against any and
all losses, claims, damages or liabilities, joint or several, and expenses
(including any amounts paid in any settlement effected with BAMSI's consent,
which consent shall not be unreasonably withheld) to which any Indemnified Party
may become subject under the Securities Act, state securities or blue sky laws,
common law or otherwise, insofar as such losses, claims, damages or liabilities
(or actions or proceedings in respect thereof, whether or not such Indemnified
Party is a party thereto) or expenses arise out of or are based upon (i) any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such securities were registered under the
Securities Act, any preliminary, final or summary prospectus contained therein,
or any amendment or supplement thereof, (ii) any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading or (iii) any violation by BAMSI of any
federal, state or common law rule or regulation applicable to BAMSI and relating
to action required of or inaction by BAMSI in connection with any such
registration, and BAMSI will reimburse such Indemnified Party for any legal or
any other expenses reasonably incurred by it in connection with investigating or
defending any such loss, claim, liability, action or proceeding; provided,
                                                                 -------- 
however, that BAMSI shall not be liable to any Indemnified Party in any such
- -------                                                                     
case to the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of or is based upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement or amendment or supplement thereof or in any
such preliminary, final or summary prospectus in reliance upon and in conformity
with written information with respect to such Holder furnished to BAMSI by such
Holder specifically for use in the preparation thereof.  Such indemnity shall
remain in full force and


                                     -12-          Registration Rights Agreement
<PAGE>
 
effect regardless of any investigation made by or on behalf of such Holder or
any Indemnified Party and shall survive the transfer of such securities by such
Holder.

     (b)  Indemnification by the Holders and the Underwriters.  BAMSI may
          ---------------------------------------------------            
require, as a condition to including any Registrable Shares in any registration
statement filed in accordance with Section 2 or 4 hereof, that BAMSI shall have
received an undertaking reasonably satisfactory to it from the Holders of such
Registrable Shares or any underwriter to indemnify and hold harmless (in the
same manner and to the same extent as set forth in Section 8(a) hereof) BAMSI
with respect to any statement or alleged statement in or omission or alleged
omission from such registration statement, any preliminary, final or summary
prospectus contained therein, or any amendment or supplement, if such statement
or alleged statement or omission or alleged omission was made in reliance upon
and in conformity with written information with respect to the Holders of the
Registrable Shares being registered or such underwriter furnished to BAMSI by
such Holders or such underwriter specifically for use in the preparation of such
registration statement, preliminary, final or summary prospectus or amendment or
supplement, or a document incorporated by reference into any of the foregoing;
provided, however, that no such Holder shall be liable for any indemnity claims
- --------  -------                                                              
in excess of the amount of the net proceeds received by such Holder from the
sale of Registrable Shares.  Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of BAMSI or any of
the Holders, or any of their respective Affiliates (other than BAMSI),
directors, officers or controlling Persons, and shall survive the transfer of
such securities by such Holder.

     (c)  Notices of Claims, Etc.  Promptly after receipt by an indemnified
          ----------------------
party hereunder of written notice of the commencement of any action or
proceeding with respect to which a claim for indemnification may be made
pursuant to this Section 8, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action; provided, however, that the failure
                                            --------  -------
of the indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under this Section 8, except to the extent
that the indemnifying party is actually materially prejudiced by such failure to
give notice. In case any such action is brought against an indemnified party,
the indemnifying party will be entitled to participate in and to assume the
defense thereof, with counsel satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof other than reasonable costs of
investigation; provided, however, that the indemnified party shall have the
               --------  -------                                           
right, at the sole cost and expense of the indemnifying party, to employ counsel
to represent the indemnified party and its respective controlling persons,
directors, officers, employees or agents who may be subject to liability arising
out of any claim in respect of which indemnity may be sought by the indemnified
party against such indemnifying party under this Section 8 if (i) the employment
of such counsel shall have been authorized in writing by such indemnifying party
in connection with the defense of such action, (ii) the indemnifying party shall
not have promptly employed counsel reasonably satisfactory to the indemnified
party to assume the defense of such action or counsel, or (iii) any indemnified
party shall have reasonably


                                     -13-          Registration Rights Agreement
<PAGE>
 
concluded that there may be defenses available to such indemnified party or its
respective controlling persons, directors, officers, employees or agents which
are in conflict with or in addition to those available to an indemnifying party;
provided, further, that the indemnifying party shall not be obligated to pay for
- --------  -------                                                               
more than the expenses of one firm of separate counsel for the indemnified party
(in addition to the reasonable fees and expenses of one firm serving as local
counsel).  No indemnifying party will consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such indemnified party of a release from
all liability in respect to such claim or litigation.

     (d)  If the indemnification provided for in this Section 8 shall for any
reason be unavailable to any indemnified party under Section 8(a) or 8(b) hereof
or is insufficient to hold it harmless in respect of any loss, claim, damage or
liability, or any action in respect of any loss, claim, damage or liability, or
any action in respect thereof referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, claim, damage or liability, or action in respect thereof,
(i) in such proportion as shall be appropriate to reflect the relative benefits
received by the indemnified party and indemnifying party or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) but also the relative fault of the indemnified party
and indemnifying party with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations.  Notwithstanding any
other provision of this Section 8(d), no Holder of Registrable Shares shall be
required to contribute an amount greater than the dollar amount of the proceeds
received by such Holder with respect to the sale of any such Registrable Shares.
No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     (e)  Other Indemnification.  Indemnification similar to that specified in
          ---------------------                                               
the preceding subdivisions of this Section 8 (with appropriate modifications)
shall be given by BAMSI and each Holder of Registrable Shares with respect of
any required registration or other qualification of securities under any federal
or state law or regulation other than the Securities Act.

     (f)  Non-Exclusivity.  The obligations of the parties under this Section 8
          ---------------                                                      
shall be in addition to any liability which any party may otherwise have to any
other party.

     9.   Rule 144.  BAMSI covenants that it will file in a timely manner the
          --------                                                           
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations promulgated thereunder (or, if BAMSI is not
required to file such reports, it will, upon the request of any Holder of
Registrable Shares, make publicly available such information), and it will take
such further action as any Holder of Registrable Shares may reasonably request,
all to the extent required from time to time to enable such Holder to sell
Registrable Shares without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act,
as such Rule may be


                                     -14-          Registration Rights Agreement
<PAGE>
 
amended from time to time, or (b) any similar rule or regulation hereafter
adopted by the SEC.  Upon the request of any Holder of Registrable Shares, BAMSI
will deliver to such Holder a written statement as to whether it has complied
with such requirements.

     10.  Assignability.  This Agreement shall be binding upon and shall inure
          -------------                                                       
to the benefit of the parties hereto and their respective successors and
permitted assigns.  Except as provided herein, no party may assign any of its
rights or delegate any of its duties under this Agreement without the express
consent of the other parties hereto.  In addition, and whether or not any
express assignment shall have been made, the provisions of this Agreement which
are for the benefit of the parties hereto other than BAMSI shall also be for the
benefit of and enforceable by any subsequent Holder of any Registrable Shares,
subject to the provisions contained herein.  Any Holder may assign any of its
rights or delegate any of its duties under this Agreement, in whole or in part,
without any prior consent of BAMSI only to a Person (a "Designated Transferee")
(a) who is an Affiliate of the Bank or BANW or (b) who is a transferee of
Registrable Shares (whether through purchase, share exchange, bequest or
otherwise) and who agrees to be bound by the terms of this Agreement.  Any
purported assignment in violation of this Section 10 shall be void.

     11.  Notices.  Any and all notices, designations, consents, offers,
          -------                                                       
acceptances or any other communications shall be given in writing by either (a)
personal delivery to and receipted for by the addressee or by (b) telecopy or
registered or certified mail which shall be addressed, in the case of BAMSI, to:
BA Merchant Services, Inc., One South Van Ness Avenue, 5th Floor, San Francisco,
California 94103, attention: General Counsel #3710; in the case of Holders, to
the address or addresses thereof appearing on the books of BAMSI or of the
transfer agent and registrar for its Class A Common Stock.  All such notices and
communications shall be deemed to have been duly given and effective: when
delivered by hand, if personally delivered; two business days after being
deposited in the mail, postage prepaid, if mailed; and when receipt is
acknowledged, if telecopied.

     12.  No Inconsistent Agreements.  BAMSI will not hereafter enter into any
          --------------------------                                          
agreement with respect to its securities which is inconsistent with the rights
granted to the Holders in this Agreement.

     13.  Specific Performance.  BAMSI acknowledges that the rights granted to
          --------------------                                                
the Holders in this Agreement are of a special, unique and extraordinary
character, and that any breach of this Agreement by BAMSI could not be
compensated for by damages.  Accordingly, if BAMSI breaches its obligations
under this Agreement, the Holders shall be entitled, in addition to any other
remedies that they may have, to enforcement of this Agreement by a decree of
specific performance requiring BAMSI to fulfill its obligations under this
Agreement.  BAMSI consents to personal jurisdiction in any such action brought
in the United States District Court for the Northern District of California or
any such other court and to service of process upon it in the manner set forth
in Section 11 hereof.

     14.  Severability.  If any provision of this Agreement or any portion
          ------------                                                    
thereof is finally determined by a court of competent jurisdiction to be
unlawful or unenforceable, such provision or portion thereof shall in no way
affect any other provision of this


                                     -15-          Registration Rights Agreement
<PAGE>
 
Agreement, the application of any such provision and any other circumstances,
and any portion of such invalidated provision that is not invalidated by such a
determination shall remain in full force and effect.

     15.  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall be deemed an original and all of which,
together, shall constitute one and the same instrument.

     16.  Defaults.  A default by any party to this Agreement in such party's
          --------                                                           
compliance with any of the conditions or covenants hereof or performance of any
of the obligations of such party hereunder shall not constitute a default by any
other party.

     17.  Amendments, Waivers.  This Agreement may not be amended, modified or
          -------------------                                                 
supplemented and no waivers of or consents to or departures from the provisions
hereof may be given unless consented to in writing by BAMSI and the holders of a
majority of the Registrable Shares; provided, however, that no such amendment,
                                    --------  -------                         
supplement, modification or waiver shall deprive any Holder of any rights under
Section 2 or 4 hereof without the consent of such Holder.

     18.  Construction.  The captions contained in this Agreement are for
          ------------                                                   
reference purposes only and shall not constitute a part of this Agreement.
Unless the context requires otherwise, the use of the masculine shall include
the feminine, and the use of the singular shall include the plural.  The word
"including" shall mean "including, without limitation."

     19.  Attorneys' Fees.  In any action or proceeding brought to enforce any
          ---------------                                                     
provision of this Agreement, or where any provision hereof is validly asserted
as a defense, the successful party shall be entitled to recover reasonable
attorneys' fees in addition to any other available remedy.

     20.  Third Party Beneficiaries.  Except as expressly provided in this
          -------------------------                                       
Agreement, the parties hereto intend that this Agreement shall not benefit or
create any right or cause of action in or on behalf of any person other than the
parties hereto.

     21.  Entire Agreement.  This Agreement contains the entire agreement among
          ----------------                                                     
the parties hereto with respect to the transactions contemplated herein and
understandings among the parties relating to the subject matter hereof.  Any and
all previous agreements and understandings between or among the parties hereto
regarding the subject matter hereof are, whether written or oral, superseded by
this Agreement.

                                LEASE AGREEMENT



          This Lease is made as of December 3, 1996 between Bank of America
National Trust and Savings Association and Bank of America NW, National
Association, both national banking associations, as lessors (together the
"Lessors" and each individually a "Lessor"), and BA Merchant Services, Inc.
("BAMSI"), a corporation organized under the laws of the State of Delaware, as
lessee.

1.   FACILITIES, SERVICES AND COMPENSATION

     A.   The Lessors shall provide BAMSI office space for the transaction of
          its business at the locations indicated on the attached Schedule A.

     B.   BAMSI will pay to the Lessors monthly rental in an amount equal to one
          twelfth the annual rent for each property as shown on the attached
          Schedule A, payable monthly in advance by the fifth business day of
          each month, which payment will include compensation for office space,
          utilities and access to other portions of the premises where BAMSI is
          located as may be required for the needs of BAMSI.

     C.   The rental payments are intended to be fair and reasonable
          compensation for the facilities in accordance with payments for
          comparable facilities, and shall be reasonably adjusted from time-to-
          time by mutual consent of the parties, to result in continued fair and
          reasonable compensation to the Lessors.

     D.   The Lessors shall provide BAMSI with additional office space under
          such terms and conditions as may be mutually agreed by the Lessor and
          BAMSI from time to time.

     E.   The Lessors will also provide BAMSI with access to limited space (e.g.
          a desk or conference room) in other premises without additional
          compensation, it being understood that the rental payments indicated
          on Schedule A include compensation for such additional space.  Any
          such additional space will be subject to availability and such
          reasonable limitations or conditions that may be imposed by the
          Lessors.

                                       1
<PAGE>
 
2.   INDEPENDENT CONTRACTOR:  In performing the services called for under this
     Lease, the Lessors are for all purposes an independent contractor of BAMSI,
     each with exclusive control over its employees and agents engaged in the
     performance of the services provided by the Lessors under this Lease.

3.   INDEMNIFICATION:  BAMSI must defend and indemnify the Lessors against and
     hold each harmless from any and all claims made by third parties for loss
     or damage arising directly or indirectly from any and all services provided
     by the Lessors pursuant to this Lease, except that due to the knowing and
     willful misconduct of a Lessor.  In the foregoing sentence the words "loss
     or damage" include, but are not limited to, loss or damage arising directly
     or indirectly from any actions or omissions of any employee or authorized
     representative of NT&SA or NW.

4.   CONFIDENTIALITY:  All information disclosed by any party to the another
     under the terms of this Lease, except such information as may be generally
     available to the public or the banking industry, is and will be kept
     confidential unless its disclosure is required by law or is required to be
     submitted to the regulatory supervisor(s) of either party.

5.   TERMS OF THE LEASE:

     A.   Unless sooner terminated as hereinafter provided, this Lease is in
          effect for 5 years from the date hereof.  At the expiration of the 5-
          year term, and of any succeeding 5-year term, this Lease is
          automatically renewed and extended for another 5-year term, unless a
          Lessor or the Lessee gives at least 6 months notice in writing of its
          intention not to renew or extend.

     B.   A Lessor or the Lessee may terminate this Lease with respect to any
          covered location at any time upon 6 months prior written notice to the
          other party.

     C.   The foregoing notwithstanding, this Lease terminates immediately if at
          any time a majority of the voting securities of BAMSI is not owned,
          directly or indirectly, by BankAmerica Corporation.

6.   NOTICES:  All notices relating to this Lease must be in writing and will be
     considered to have been given by either party to the other party upon
     personal delivery 

                                       2
<PAGE>
 
     to a party's designated representative or upon the mailing thereof to the
     other party by registered or certified mail at its address set forth on the
     signature page of this Lease, or to such other address as the other party
     may specify in writing.

7.   BREACH:  Upon the breach of any obligation under this Lease by either
     party, the aggrieved party must give to the defaulting party notice of such
     breach which notice must specify the exact nature of the breach.  If this
     Lease is terminated, the right of the aggrieved party to any damages for
     such breach shall not be prejudiced.

8.   INTEGRATION:  This Lease supersedes all oral communications and prior
     writings in respect of the subject matter hereof.  In the event of any
     conflict between the terms, conditions and provisions of this Lease and
     those of any other prior agreements, documents or communications, the terms
     and conditions of this Lease shall prevail.

9.   CHOICE OF LAW:  This Lease is governed by and construed in accordance with
     the laws of the State where the real property is located.

10.  SUBLEASE:  If this Lease is a sublease "Lessor" means the tenant of the
     master landlord under a master lease (a copy of which has been previously
     provided) and "BAMSI" means the subtenant under the master lease for the
     premises specified in paragraph 1.A. above.  BAMSI takes such premises
     subject to and agrees to abide by all of the provisions of the master
     lease.

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

     1.1   Applicability of Article I.  The Bank and BAMSI agree and acknowledge
           --------------------------                                           
that, depending on various factors, including Merchant (as hereinafter defined)
location and the requirements of Visa or MasterCard rules and regulations, to
the extent such rules and regulations are applicable, BAMSI shall act as the
Bank's Member Service Provider (as defined in such rules and regulations) with
respect to certain Merchants in connection with the provision of Merchant
Processing Services (as hereinafter defined) and the provisions of this Article
I shall operate to govern such relationship.

     1.2   Appointment as Agent.  The Bank appoints BAMSI, and BAMSI agrees to

respect to credit, debit and charge card transactions under the Visa,
MasterCard, Diners Club, AMEX, JCB, Carte Blanche, Discover, Interlink and other
programs ("Merchant Processing Services") to merchants who desire to receive

its BIN, ICA and any other Visa and MasterCard identification numbers to the

     1.3   Performance by BAMSI.  BAMSI shall have full responsibility for the

services to the Merchants, perform data capture services with respect to all
credit, debit and charge card transactions by the Merchants, submit such data to
the applicable Interchange (as hereinafter defined), process retrievals and
chargebacks, and direct the settlement of such transactions. In providing

("Rules"), (ii) all agreements between Merchants and the Bank with respect to
Merchant Processing Services, and (iii) all applicable laws and regulations,

subject to the rights of BAMSI to terminate this Agreement pursuant to 
Section 6.2. Without in any way limiting the foregoing, BAMSI agrees as follows:

acting as agent or representative of the Bank; (b) any solicitation material
used by BAMSI shall clearly disclose that BAMSI is acting as agent or
representative of the Bank; and (c) BAMSI acknowledges that it does not have
authority to permit the use of Visa Card Program Marks by any of its own agents.

from time to time to reflect any changes in Visa's requirements applicable to
BAMSI's use of Visa Card Program Marks and solicitation material or to the terms
required herein.

     1.4   Merchant Contracts.  BAMSI, as agent of the Bank, shall be
           ------------------

Contracts, to modify Merchant Contracts to the extent necessary to assign them
to the Bank, to perform the Merchant Contracts and to take other necessary or
appropriate actions with respect to the Merchant Contracts, all in accordance

shall be responsible for all credit, fraud and other risks associated with each
Merchant Contract.

net amount due to an account established by the Bank for the purpose of
receiving all settlement amounts paid by Visa and MasterCard with respect to the

     hereunder.  Such payments to Merchants shall be effected through mutually
     acceptable procedures which are consistent with the payment procedures

     Bank's behalf all of the administrative and bookkeeping functions necessary
     to effect payment in such manner.

     1.8   Due Diligence by the Bank; BAMSI's Standards.
           -------------------------------------------- 

           (a) Due Diligence Prior to Execution of Agreement.  Senior management
               ---------------------------------------------                    
     officials of BAMSI have met with the Bank and have discussed with the Bank
     officials the credit and financial review procedures and standards used by
     BAMSI in deciding whether to accept or retain Merchants as customers for
     Merchant Processing Services, as well as BAMSI's experience with respect to
     any losses resulting from financial failures or fraud by its merchant
     customers.  Schedule A attached hereto outlines the credit and financial
     review procedures and standards currently used by BAMSI.

           (b) Continuing Due Diligence:  BAMSI's Risk Standards.  BAMSI shall
               -------------------------------------------------              
     keep the Bank advised of any material changes in the credit and financial
     review procedures and standards and of any material exceptions to such
     procedures and standards which may from time to time be made with respect
     to particular Merchants.  BAMSI shall not make any such changes or
     exceptions until its senior management has approved such changes or
     exceptions after carefully evaluating the relative advantages and
     disadvantages

                                      -4-                  Sponsorship Agreement
<PAGE>
 
     expected to result from such changes or exceptions.  BAMSI also shall
     continue to advise the Bank on a timely basis with respect to any
     substantial loss (meaning any loss of $1,000,000 or more in the aggregate
     in any twelve month period) incurred by BAMSI as a result of any financial
     failures or fraud by its merchant customers.  If the Bank reasonably
     determines from time to time that any changes are needed in BAMSI's credit
     and financial review procedures and standards or in the implementation
     thereof in order to avoid any significant increase in BAMSI's losses from
     financial failures or fraud by its merchant customers, then the Bank shall
     so notify BAMSI in writing, and BAMSI and the Bank shall mutually agree
     upon, and BAMSI shall implement appropriate changes.

           (c) Due Diligence by the Bank for BAMSI Pricing Standards.  Senior
               -----------------------------------------------------         
     management officials of BAMSI have met with the Bank and have discussed
     with the Bank officials the pricing procedures and standards used for
     Merchants as customers for Merchant Processing Services.  BAMSI shall keep
     the Bank advised of any material changes in its pricing procedures and
     standards and of any material exceptions to such procedures and standards
     which may from time to time be made with respect to particular Merchants.
     BAMSI shall not make any such changes or exceptions until its management
     committee has approved such changes or exceptions after carefully
     evaluating the relative advantages and disadvantages expected to result
     from such changes or exceptions.  If the Bank reasonably determines from
     time to time that any changes are needed in BAMSI's pricing procedures and
     standards or in the implementation thereof, then  the Bank shall so notify
     BAMSI in writing, and BAMSI and the Bank shall mutually agree upon, and
     BAMSI shall implement appropriate changes.

     2.3   Loans and Overdrafts.  Nothing in this Agreement shall be deemed to

                                  ARTICLE III

reimburse the Bank in full all interchange or issuer reimbursement fees on
outgoing merchant sales volume, as well as all fee assessments or charges
imposed on the Bank by Visa or MasterCard as a result of the Merchant Processing
Services performed by BAMSI. Such fees shall be paid by BAMSI directly when due
or shall be paid by BAMSI to the Bank on the banking day immediately prior to
the day on which the Bank must pay such fees. All such fees, assessments and
charges for which the Bank seeks payment by BAMSI shall upon request be
documented to BAMSI's reasonable satisfaction as being attributable to BAMSI's
Merchant Processing Services.

          (b) the negligent exercise of or the exceeding by any Joint Officer of

including, but not limited to, all court costs, investigation expenses and the
reasonable fees and expenses of separate counsel for the Bank selected by the
Bank, provided, however, that the Bank shall not be entitled to indemnification
as to amounts arising from the negligence or willful misconduct of the Bank.


                                   ARTICLE V

                            COMPLIANCE MODIFICATIONS
                            ------------------------

     5.1   Compliance Modifications.  In the event that:
           ------------------------                     

           (a)  the laws, rules and/or regulations or any official
     interpretations thereof applicable to the Bank as a national bank or the
     Visa or MasterCard rules and/or regulations or any official interpretations
     thereof applicable to the Bank and the matters covered by this Agreement

     contemplated hereby between the Bank and BAMSI or in the provisions of this
     Agreement are needed to comply with any such laws, rules, regulations or
     official interpretations thereof; or

           (ii) some or all of the activities contemplated by this Agreement are
     prohibited; or

           (b)  Visa or MasterCard requires, as a condition to performance of
     this Agreement, that BAMSI enter into an agreement with Visa or MasterCard
     that BAMSI considers unacceptable;

then at BAMSI's request, the parties will cooperate in making any modifications
to this Agreement and to the parties' relationship hereunder to the extent any
such modifications will permit BAMSI to continue processing, settling and
authorizing bankcard transactions (or continue performing some of such
functions) in compliance with the laws, rules, regulations or any official

both parties hereto.  The terms of this Agreement shall govern all such
additional Schedules.

     (c)  The Bank and BANW shall use good faith efforts to provide the Services
and any Additional Services in a good, workmanlike and professional manner.

     (d)  Subject to the provisions of Section 6, (i) BAMSI shall afford to the

reasonable access to

to all information related to the Services or the Additional Services produced
or generated by the Bank or BANW in the course of providing the same, including
without limitation, technical, economic and business data, computer information

BANW in accordance with the attached Schedules and any additional Schedules on a
quarterly basis, in arrears or on such other basis as the parties may mutually
agree, commencing on December 31, 1996, and at the end of each subsequent fiscal
quarter for as long as this Agreement remains in effect.

     3.   Term and Termination.
          -------------------- 

     (a)  The Bank and BANW shall provide the Services to BAMSI hereunder for
the period beginning on the effective date of this Agreement, and ending on a
date five years from the date hereof or, with respect to each particular Service
or Additional Service, on the date specified in a notice of termination
delivered pursuant to Section 3(b) below with respect to such Service or
Additional Service. Thereafter, on the anniversary of this Agreement, BAMSI may
renew this Agreement for successive one-year terms (each such successive one-
year term, an "Additional Term") at its option; provided, however, that the Bank
                                                --------  -------

by giving 90 days' prior written notice to the Bank and BANW, provided that any
terminated Service or Additional Service may be renewed by the parties in
accordance with Section 1(b) above.  If either party shall default in the
performance of any of its material obligations under this Agreement and shall
fail or refuse to remedy such default to the reasonable satisfaction of the
other party within 30 days after receipt of written notice, the non-breaching
party may terminate this Agreement.  If the default in performance relates only
to a specific Service or Additional Service, termination will be limited to
termination of that Service or Additional Service.  If any party shall become
insolvent, be placed in receivership, make an assignment for the benefit of
creditors or seek relief or have a petition

filed against it under federal bankruptcy law, the other party may terminate
this Agreement immediately upon written notice.

     (c)  If action by a federal, state or other governmental regulatory agency
materially affects a party's rights or obligations hereunder, such party may
terminate any portion of the Services or Additional Services or this Agreement
by giving 90 days' prior written notice to the other, or such shorter period as
may be required by such agency or by law.

     (d)  The Bank or BANW may terminate this Agreement at any time upon 90
days' prior written notice to BAMSI in the event BAC and its affiliates (other
than BAMSI) beneficially own shares representing less than a majority of the
voting power of the outstanding common stock of BAMSI.

     (e)  The Bank or BANW may terminate this Agreement upon expiration or
termination of the Corporate Opportunities Agreement, the License Agreement or
the Marketing Agreement.

any reason shall not terminate the obligations described in Sections 3(g), 4 and
6 which shall survive any such termination.

terminate either party's obligations or rights arising out of any act or
omission of such party occurring prior to such termination or expiration.

          ---------------                                                   
other party and its officers, directors, employees, agents, representatives and
attorneys-in-fact from and against any claims or liabilities which may arise in
connection with the Services and/or Additional Services, unless such claims or
liabilities arise directly out of the gross negligence or willful misconduct of
the party or person seeking indemnification.

                        TAX ALLOCATION AGREEMENT BETWEEN
                       BAC AND BA MERCHANT SERVICES, INC.


     This Tax Allocation Agreement ("Agreement"), made this ___ day of December
1996, by and between BankAmerica Corporation ("BAC") and BA Merchant Services,
Inc. ("BAMSI").

     Whereas, a consolidated U.S. federal income tax return ("Consolidated
Return") is filed which includes BAC and all domestic, Canadian and certain
Mexican subsidiaries ("Consolidated Group").  BAC will include BAMSI in its
consolidated federal income tax return relating to periods during which the
members of the Consolidated Group own 80 percent of the voting power and 80
percent of the value of the stock of BAMSI within the meaning of section 1504 of
the Internal Revenue Code.

     Whereas, consolidated, combined, joint or unitary income tax and franchise
tax returns on income ("Combined Returns") are also filed, as required by
certain state and local jurisdictions, including California.

     Whereas, certain direct and indirect subsidiaries of BAC join in filing
Consolidated and/or Combined Returns (the "BAC Group")

     Whereas, there will be periods during which BAMSI will join BAC in filing
either Consolidated or Combined Returns or both ("Affiliation Periods").

     Whereas, BAMSI anticipates that it will sell 14,000,000 shares of its Class
A Common Stock to the public in an initial public offering (the "IPO")
(16,100,000 if the underwriters exercise their over-allotment option) and that
as a result, BAMSI will thereafter cease to be included in the Consolidated
Group (although BAMSI may continue to be included in certain Combined Returns);

     Whereas, the parties wish to set forth in this Agreement the agreement
between BAC and BAMSI with respect to the allocation and settlement of the
federal, state and local taxes of the BAC Group and the agreement between BAC
and BAMSI with respect to the resolution of tax controversies;

     Now, therefore, in consideration of the mutual covenants contained herein,
the parties agree as follows:
<PAGE>
 
1.   Filing of Returns
     -----------------

     With respect to each Affiliation Period, BAC shall file, and BAMSI shall
agree to join in the filing of, Consolidated Returns and/or Combined Returns on
behalf of the BAC Group.  BAMSI shall execute and file such consents, elections
and other documents as BAC reasonably requests with respect to the filing of the
BAC Group's Consolidated and Combined Returns and shall timely provide to BAC
such information as may be necessary for the filing of such returns or for the
determination of amounts due under this Agreement.  BAMSI acknowledges and
agrees that the rights conferred upon BAC in connection with the filing of the
BAC Group's returns include, without limitation, the right to reasonably
determine the allocation of income (or loss) of BAC and BAMSI between the last
Affiliation Period and the next taxable period (including the allocation of tax
liability with respect to the date of the IPO).  BAMSI shall file all required
Federal, state, local and foreign tax returns with respect to all periods for
which BAMSI is not includible on a return of BAC, and BAMSI shall be responsible
for the payment of all taxes in connection therewith.  BAMSI shall file any such
tax returns in a manner consistent with the manner in which BAC filed its
returns for Affiliation Periods (except as required by law or to the extent any
inconsistency would not adversely affect the returns of the BAC Group).

     For purposes of any Affiliation Period and any taxable period for which
BAMSI is included in any Consolidated Return or any Combined Returns, BAC and
BAMSI will settle taxes on income in the manner described below.  BAC and BAMSI
will use the same settlement procedure for payments made between BAC and BAMSI
after BAMSI ceases to be a member of the BAC Group, which are attributable to
adjustments made to Affiliation Periods.

2.   Allocation and Settlement of U.S. Federal Consolidated and Combined State
     -------------------------------------------------------------------------
     Income Taxes
     ------------

     BAMSI will determine and settle its share of the Consolidated/Combined
income taxes based upon income taxes currently payable on a separate return
basis as modified below.

     BAMSI will receive tax payments in the current year for its net operating
loss, its net capital loss, and its excess foreign tax credits and general
business credits (hereinafter referred to as "Tax Benefit Items"), as computed
on a separate return basis, provided these Tax Benefit Items can be carried back
on a separate return basis.

     If BAMSI's Tax Benefit Items cannot be carried back on a separate return
basis, but are utilized in the Consolidated/Combined Returns, BAMSI will receive
a tax payment equal to the reduction of the Consolidated/Combined tax liability
relating to the utilization of BAMSI's Tax Benefit Items.

                                                                              2.

<PAGE>
 
     If more than one corporation has Tax Benefit Items which cannot be carried
back on a separate return basis and the full amount of such items are not
utilized in the Consolidated/Combined Returns, each corporation receives a pro-
rata tax payment equal to the reduction of the Consolidated/Combined tax
liability relating to the utilization of the corporation's Tax Benefit Items.
Any such Tax Benefit Items not utilized in the Consolidated/Combined Return are
carried forward.  The specific ordering rules prescribed by the taxing
authorities are applied in computing the utilization of Tax Benefit Items.

     Tax Benefit Items utilized in the Consolidated/Combined Returns for which a
tax payment was received by BAMSI will be excluded from the computation of
BAMSI's tax liability on a separate return basis for any succeeding year.

3.   Controlled Group Tax Benefits
     -----------------------------

     Controlled group tax items, including apportionment of rate brackets,
minimum tax exemption, environmental tax exemption, and other similar items, are
determined on a Consolidated/Combined basis.  The controlled group tax items are
allocated to each corporation in the BAC Group on an equitable and consistent
basis if such items are claimed on a Consolidated/Combined return.

4.   Alternative Minimum Tax ("AMT") and Alternative Minimum Tax Credit ("AMTC")
     ---------------------------------------------------------------------------

     AMT is determined on a Consolidated/Combined basis and allocated to each
corporation on an equitable and consistent basis.  The allocation is based upon
each corporation's tax preferences, tax adjustments and other items causing the
AMT in the Consolidated/Combined return.  AMT is not allocated to any
corporation that does not have any tax preferences, positive tax adjustment
items or other items causing AMT.  The total amount of AMT allocated to each
corporation cannot exceed the Consolidated AMT and the Combined AMT, for any
given state, in any tax year.

     In future years, as any Consolidated/Combined return AMTC is utilized, AMTC
is allocated to each corporation on an equitable and consistent basis.  This
allocation is based upon the amount of AMT that had been previously allocated to
each corporation. To the extent that AMTC would otherwise be allocated to BAMSI,
if BAMSI had not left the BAC Group, due to an allocation of AMT to BAMSI during
an Affiliation Period, BAMSI shall be entitled to a payment from BAC in an
amount equivalent to such AMTC.  The total amount of AMTC allocated to each
corporation cannot exceed the consolidated AMTC claimed in any tax year.

                                                                              3.

<PAGE>
 
5.   Combined State and Local Income and Franchise Taxes on Income
     -------------------------------------------------------------

     The tax liability of Combined Returns is calculated by applying BAMSI's
apportionment factors, as computed on a separate return basis, to BAMSI's
separate return taxable income using the tax accounting method applicable to the
state or local tax jurisdictions.


6.   Tax Settlement Payments
     -----------------------

     In addition to settlements required by paragraphs 7 and 8, tax settlement
payments between BAC and BAMSI are made as follows:

     (a) BAMSI will pay or receive its current year estimated tax liability or
refund, as computed on a separate return basis, at the respective quarterly
installment due dates, including the original return due date.

     (b) BAMSI will pay BAC the amount of taxes or receive tax overpayments, as
computed on a separate return basis, (less previous settlements, if any) on the
extended due dates of the Consolidated/Combined Returns.

     (c) BAMSI will receive a refund from BAC in the current
Consolidated/Combined year of previously paid taxes for Tax Benefit Items that
can be carried back on a separate return basis.

     (d) BAMSI will receive a payment from BAC in the current year for the
reduction in the Consolidated/Combined tax liability that results from the
utilization of its Tax Benefit Items not utilized previously on a separate or
Consolidated/Combined basis.

     (e) Federal and Combined taxes attributable to or from each foreign
subsidiary or branch of BAMSI will be settled directly with BAMSI.

     (f) BAMSI will settle all taxes of separately filed tax returns directly
with the individual tax jurisdictions.
 
7.   Restructuring Taxes
     -------------------

     Notwithstanding any other provision of this agreement, any amount payable
with respect to Restructuring Taxes and any related costs imposed upon any
member of the BAC Group shall be allocated in the year determined between the
BAC Group and BAMSI in accordance with Schedule A.  "Restructuring Taxes" shall
mean any taxes resulting from transactions contemplated by the transfer of
assets to BAMSI by other BAC Group members or the

                                                                              4.

<PAGE>
 
assumption by BAMSI of liabilities of such other BAC Group members in connection
with such transfers.

8.   Subsequent Return Adjustments
     -----------------------------

     In the event the Consolidated or Combined Returns are amended or adjusted
(whether by reason of the filing of an amended return, a claim for refund, or
otherwise) the liability of BAMSI will be redetermined, adjusted and settled on
a separate return basis consistent with the above provisions.

     In the event the Consolidated or Combined tax liability is redetermined or
adjusted pursuant to an audit or challenge by the taxing authorities, or if a
voluntary tax payment is made to limit the accrual of interest on audit issues,
the tax liability of BAMSI will be redetermined, adjusted and settled, as
appropriate.  Payments reflecting such redeterminations or adjustments shall be
made when (a) a settlement (evidenced in writing or by the payment of taxes) is
entered into with the taxing authority, (b) a decision of a court having
jurisdiction in the matter becomes final and is not subject to appeal, or (c)
BAC makes a voluntary tax payment on behalf of the BAC Group with respect to the
Consolidated or Combined Returns.

     BAC may allocate the liability for any redetermination or adjustment on a
tentative basis among the member corporations and BAMSI in accordance with its
estimate of each corporation's liability on a separate return basis.  The
tentative allocations will be revised and settled when return adjustments are
finalized.

9.   Penalties and Interest
     ----------------------

     If penalties or interest are imposed by the taxing authorities, or if a
voluntary interest payment is made, the payment is allocated to and made by each
responsible corporation.  If any interest from the taxing authorities is
received by BAC or its subsidiaries included in the Consolidated or Combined
Returns, such interest shall be allocated and refunded to the attributable
corporation.

10.  Billing
     -------

     The Tax Department of Bank of America NT&SA determines the tax settlements
and provides written notification of the tax payments and refunds at the
respective installment due dates for estimated tax payments and at the original
and extended due dates of the Consolidated/Combined Returns.

     In addition, written notification of any tax payment or overpayment for
adjustments reflected in amended returns and tax audits and of any Restructuring
Taxes will also be provided by the Tax Department, as appropriate.

                                                                              5.

<PAGE>
 
     Payments of income taxes, penalties and interest are payable within thirty
(30) days of billing.  If payment is not made within the thirty-day period,
interest is charged from the date of billing to the date of payment.  Interest
accrues on the late payment at the same rate used by the taxing authorities on
late payments during such period.

11.  Determinations and Disputes
     ---------------------------

     Subject to section 12 of this Agreement, in the event that any dispute must
be settled under this Agreement, the parties hereto agree to submit the issue in
writing to the Tax Advisory Committee ("Committee") for its review and
recommendation, with the final decision to be made by the Chief Accounting
Officer.  The Committee consists of the Director of Tax and representatives from
Corporate Finance and Corporate Treasury.  The Committee shall permit a
representative of BAMSI to participate in the review as appropriate.  In the
event that reasonable mutual satisfaction cannot be reached between BAC and
BAMSI with respect to a final decision of the Chief Accounting Officer, the
dispute may be submitted to arbitration as described below.

     Any dispute, controversy or claim between BAC and BAMSI arising out of or
relating to this Agreement, or any agreements or instruments relating hereto or
delivered in connection herewith, will be resolved by arbitration conducted in
San Francisco, California under the auspices and according to the Commercial
Arbitration Rules of the American Arbitration Association.  The arbitration
shall be conducted in accordance with the United States Arbitration Act (Title
9, U.S. Code), notwithstanding any choice of law provision in this Agreement.

12.  Procedural Matters
     ------------------

     (a) To the extent that BAMSI remains part of the Consolidated Return for
federal income tax purposes or part of a Combined Return, the Tax Department
will prepare and file Consolidated and Combined Returns, along with any other
documents or statements that are required to be filed with the taxing
authorities for the U.S. federal, state or local purposes, related to
Consolidated and Combined Returns.  In its sole discretion, with respect to any
Consolidated/Combined Return which it has filed or will file, BAC has the right
to

          (i)  Determine:

          1)   The manner in which such returns, documents or statements
are prepared and filed including, without limitation, the manner in which any
item of income gain, loss, deduction or credit shall be reported;

          2)   The manner in which the Consolidated or Combined tax liability
will be allocated for the purpose of

                                                                              6.
<PAGE>
 
determining the taxable earnings and profits of each corporation;

              3)   Whether any extensions may be requested; and

              4)   The elections that are made by any corporation included in
BAC's Consolidated/Combined Returns.

         (ii) Except as otherwise expressly provided in (b) and (c), contest,
compromise or settle any adjustment or deficiency proposed, asserted or assessed
as a result of any audit of such returns by the taxing authorities;

        (iii) File, prosecute, compromise or settle any claim for refund; and

         (iv) Determine whether any refunds to which BAC and its subsidiaries
may be entitled are paid by way of refund or credited against the tax liability
of BAC and its subsidiaries.

     Without limiting its rights and obligations, BAMSI hereby irrevocably
appoints BAC as its agent and attorney-in-fact to take such action (including
the execution of documents) as BAC may deem appropriate to effect the foregoing.

     Filing positions taken in the Consolidated/Combined Returns may adversely
impact the computation of separate return tax liabilities of certain
corporations.  Accordingly, the Tax Department will calculate each corporation's
separate return tax liability or refund using the different filing basis that
would be available to the corporation had it filed a separate return, if it
results in a material difference in computing the corporation's separate tax
liability.

     (b) If any party receives notice of a tax examination, audit or challenge
involving amounts subject to this Agreement, such party shall timely notify the
other party of the information and shall provide the other party with a written
copy of any relevant letters, forms or schedules received from any taxing
authority or otherwise in its possession and shall provide notice and
information relating to all material proceedings in connection therewith.  In
any audit conference or other proceeding with any taxing authority or in any
judicial proceedings concerning the determination of the tax liabilities of the
BAC Group or any of its members, including BAMSI, the BAC Group and each of its
members shall be represented by persons selected by BAC, except that BAMSI shall
select its own representative; provided however, the settlement and terms of
settlement of any issues relating to such audits shall be in the sole discretion
of BAC. In the event that BAMSI can show, by clear and convincing evidence, that
any such settlement or the terms of such settlement unreasonably and adversely
affects BAMSI, the resulting dispute between BAC and BAMSI may be submitted to
arbitration as described above in Section 11.

                                                                              7.

<PAGE>
 
     BAC shall have the right to review BAMSI's separate returns and records
relating thereto with respect to issues which are relevant for BAC's returns.
Such access shall be provided on a reasonable basis.  BAC shall have a right to
participate in audits of BAMSI's separate returns with respect to issues which
are relevant for BAC's returns; provided however, the settlement and terms of
settlement of any issues relating to such audits shall be in the sole discretion
of BAMSI.  In the event that BAC can show, by clear and convincing evidence,
that such settlement or the terms of such settlement unreasonably and adversely
affect BAC, the resulting dispute between BAC and BAMSI may be submitted to
arbitration as described above in Section 11.

     (c) Notwithstanding (b), so long as any proposed deficiency solely involves
a tax issue of BAMSI, BAC shall contest such issue to the extent requested in
writing by BAMSI and shall permit BAMSI, at BAMSI's expense, to participate in
all conferences and meetings with taxing authorities with respect to the issue;
provided, however, that if (and so long as) the controversy also involves a tax
issue of BAC or member of the BAC Group other than BAMSI (whether for the
taxable year in question or another taxable year), BAC shall be entitled to the
choice of forum for the proceedings and shall have the right to make any
decision as to settlement of the contest or any issue; further, in no event
shall BAC be required to take any action requested by BAMSI unless and until (i)
BAMSI shall have given BAC an indemnity in a form satisfactory to BAC for any
liability, expense or loss arising out of or relating to BAMSI issues involved
in the dispute or contest (including, without limitation, all out-of-pocket
expenses solely of BAMSI (including internal computation costs of BAC Group
employees), costs, losses, reasonable disbursements, penalties, interest and
additions to tax relating to such issues, but excluding any expense of BAC
incurred for the purpose of monitoring the BAMSI issues) and (ii) if such
contest is to be conducted in a manner requiring payment of a proposed tax
deficiency, BAMSI shall have advanced to BAC on an interest-free basis an amount
attributable to the issue, together with any required interest or penalties.

13.  Termination
     -----------

     This Agreement between BAC and BAMSI shall terminate if BAC and BAMSI
agree, in writing, to terminate this Agreement.  In addition, BAC shall have the
right to terminate this Agreement at any time upon 30 days' prior written notice
to BAMSI, if BAC and its affiliates beneficially own less than a majority of the
voting power of the outstanding common stock of BAMSI.

     With respect to BAC and BAMSI, notwithstanding the termination of this
Agreement, the provisions herein remain in effect for any tax year in which
Consolidated/Combined Returns have been filed.


                                                                              8.
<PAGE>
 
     Upon the departure of BAMSI from the BAC Group, BAC will pay BAMSI for any
previously unpaid tax benefits relating to Tax Benefit Items that were utilized
in the Consolidated/Combined Returns.

14.  Indemnity
     ---------

     BAMSI will be indemnified by BAC for any joint and several federal income
tax liability incurred during an Affiliation Period which is not attributable to
BAMSI.

15.  Miscellaneous Provisions
     ------------------------

BAMSI with respect to the allocation and settlement of income taxes.

<PAGE>
 
       5.2  Initial Grant of Options. Each individual who is a Nonemployee
       -----------------------------
Director on the Effective Date and each individual who becomes a Nonemployee
Director following the Effective Date shall be granted an Option to purchase

       5.3  Subsequent Grants of Options. During the time period beginning
       ---------------------------------
January 1997 and ending November 30, 2006, and subject to the limitation on the
number of Shares subject to the Plan, on the day following each annual meeting
of the Company's shareholders, each Nonemployee Director shall be granted an
Option to purchase two thousand five hundred (2,500) Shares, effective as of
each such day following the annual shareholders' meeting.

       5.4  Limitation on Grant of Options. Other than those grants of Options
       ----------------------------------- 
set forth in Sections 5.1, 5.2, and 5.3 herein, no additional Options shall be

       5.5  Option Award Agreement. Each Option grant shall be evidenced by an
       ---------------------------
Award Agreement that shall specify the Option Price, the duration of the Option,
the number of Shares available for purchase under the Option, and such other
provisions as the Board shall determine.

       5.6  Option Price. The purchase price per Share available for purchase
       -----------------
under an Option shall equal the Fair Market Value of a Share on the date the

       5.7  Duration of Options. Each Option shall expire on the tenth (10th)
       ------------------------
anniversary date of its grant.

       5.8  Vesting of Shares Subject to Option. Subject to the terms of this
       ---------------------------------------- 
Plan, all Options granted under this Plan shall vest one hundred percent (100%)
upon the day preceding the first annual shareholder meeting following the grant
of such Options, and shall remain exercisable until the tenth anniversary of
their grant date.

       Regardless of the vesting schedule set forth in this Section 5.8, all
Options held by a Participant shall immediately become one hundred percent
(100%) vested upon the first to occur of the following:

       (a)  The death of the Participant; or

       (b)  The Disability of the Participant.
<PAGE>
 
       5.9  Termination of Directorship. In the event a Participant ceases to be
       --------------------------------
a Director for any reason other than death or Disability, all Options not vested
as of the effective date of termination shall be forfeited and shall revert back
to the Company (with no further vesting to occur). All Options which are vested
as of such date shall remain exercisable for six (6) months following the date
the Director's service on the Board terminates, or until their expiration date,
whichever period is shorter.

       To the extent an Option is exercisable immediately following the date of
death of a Participant, it shall remain exercisable at any time prior to its
expiration date, or for one (1) year after the date of death, whichever period
is shorter, by such persons that have acquired the Participant's rights under
the Option by will or by the laws of descent and distribution.

       To the extent an Option is exercisable immediately following the
effective date of Disability (the "Disability Date"), it shall remain
exercisable at any time prior to its expiration date, or for one (1) year after
the Disability Date, whichever period is shorter, by the Participant or such
person or persons as shall have been named as the Participant's legal
representative or beneficiary.

       5.10  Payment. Options shall be exercised by the delivery of a written
       -------------
notice of exercise to the Company, setting forth the number of Shares with
respect to which the Option is to be exercised, accompanied by full payment for
the Shares.

       The Option Price upon exercise of any Option shall be payable to the
Company in full either: (a) in cash or its equivalent, or (b) by tendering
previously acquired Shares having a Fair Market Value at the time of exercise
equal to the total Option Price (provided that the Shares tendered upon Option
exercise have been held by the Participant for at least six (6) months prior to
their tender to satisfy the Option Price), or (c) by a combination of (a) and
(b).

       As soon as practicable after receipt of a written notification of
exercise and full payment, the Company shall deliver to the Participant, in the
Participant's name, Share certificates in an appropriate amount based upon the
number of Shares purchased pursuant to the exercise of the Option.

       5.11  Restrictions on Share Transferability. The Board shall impose such
       -------------------------------------------
restrictions on any Shares acquired pursuant to the exercise of an Option under
the Plan as it may deem advisable, including, without limitation, restrictions
under applicable federal securities laws, under the requirements of any Stock
exchange or market upon which such Shares are then listed and/or traded, and
under any blue sky or state securities laws applicable to such Shares; provided,
however, that no such restriction shall be imposed if the restriction could
result in the failure to comply with the "formula award" exception for grants of
Options to Directors.
<PAGE>
 
       5.12  Nontransferability of Options. No Option granted under the Plan may
       -----------------------------------
be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated,
other than by will or by the laws of descent and distribution. Further, all
Options granted to a Participant under the Plan shall be exercisable during his
or her lifetime only by such Participant.

Article 6. Amendment, Modification, and Termination
- ---------------------------------------------------

       6.1  Amendment, Modification, and Termination. Subject to the terms set
       ---------------------------------------------
forth in this Section 6.1, the Board may terminate, amend, or modify the Plan at
any time and from time to time; provided, however, that the provisions set forth
in the Plan regarding the amount of securities to be awarded to Directors, the
price of securities awarded to Directors, and the timing of Option grants to
Directors, may not be amended more than once within any six (6) month period,
other than to comport with changes in the Code, the Employee Retirement Income
Security Act of 1974 as amended from time to time, or the rules thereunder.

       Without the approval of the stockholders of the Company (as may be
required by the Code, by the insider trading rules of Section 16 of the Exchange
Act, by any national securities exchange or system on which the Shares are then
listed or reported, or by a regulatory body having jurisdiction with respect
hereto) no such termination, amendment, or modification may:

       (a)  Change the class of Participants eligible to participate in the
            Plan; or

       (b)  Materially increase the cost of the Plan, or materially increase the
            benefits accruing to Participants.

       6.2  Awards Previously Granted. Unless required by law, no termination,
       ------------------------------
amendment, or modification of the Plan shall in any material manner adversely
affect any Option previously granted under the Plan, without the written consent
of the Participant holding the Option.

Article 7. Miscellaneous
- ------------------------

       7.1  Gender and Number. Except where otherwise indicated by the context,
       ----------------------
any masculine term used herein also shall include the feminine; the plural shall
include the singular and the singular shall include the plural.

       7.2  Severability. In the event any provision of the Plan shall be held
       -----------------
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included.
<PAGE>
 
       7.3  Beneficiary Designation. Each Participant under the Plan may, from
       ----------------------------   
time to time, name any beneficiary or beneficiaries (who may be named
contingently or successively) to whom any benefit under the Plan is to be paid
in the event of his or her death (and/or who may exercise the Participant's
vested Options following his or her death). Each designation shall revoke all
prior designations by the same Participant, shall be in a form prescribed by the
Company, and will be effective only when filed by the Participant in writing
with the Company during his or her lifetime. In the absence of any such
designation, benefits remaining unpaid at the Participant's death shall be paid
to the Participant's estate (and, subject to the terms and provisions of the
Plan, any unexercised vested Options may be exercised by the administrator or
executor of the Participant's estate).

       7.4  No Right of Nomination. Nothing in the Plan shall be deemed to
       ---------------------------
create any obligation on the part of the Board to nominate any Director for
reelection by the Company's shareholders.

       7.5  Shares Available. The Shares made available pursuant to Options
       ---------------------
under the Plan may be either authorized but unissued Shares, or Shares which
have been or may be reacquired by the Company, as determined from time to time
by the Board.

       7.6  Successors. All obligations of the Company under the Plan with
       ---------------
respect to Options granted hereunder shall be binding on any successor to the
Company, whether the existence of such successor is the result of a direct or
indirect purchase, merger, consolidation, or otherwise, of all or substantially
all of the business and/or assets of the Company.

       7.7  Requirements of Law. The granting of Options under the Plan
       ------------------------
shall be subject to all applicable laws, rules, and regulations, and to such
approvals by any governmental agencies or national securities exchanges
as may be required.

       7.8  Governing Law. To the extent not preempted by federal law, the Plan,
       ------------------
and all agreements hereunder, shall be construed in accordance with and governed
by the laws of the State of Delaware.

<PAGE>
 
Article 3. Designation of Participants
- --------------------------------------

    3.1  Each Senior Officer of the Company shall be a Participant in the Plan,
unless such officer participates in an annual cash incentive program within his
or her business unit or subsidiary.

    3.2  No member of the Committee, and no member of the Board of Directors of
BA Merchant Services, Inc. who is not also a regular salaried employee of the
Company, shall be eligible to participate in the Plan.

    3.3  The Committee may, but need not, consider for prorated or full
incentive awards Participants who have ceased employment because of death,
disability, or retirement prior to the date the Committee determines incentive
awards under the Plan. Participants who terminate employment (or give notice of
intent to terminate employment) for reasons other than death, disability, or
retirement prior to the date the Committee determines the incentive awards under
the Plan will not be eligible to be considered for an incentive award, unless
the Committee determines in its sole discretion that, because of special
circumstances, the Participant should be eligible to be considered.

    3.4  Participation in the Plan shall not entitle any officer to an award
under the Plan. All awards shall be made in the sole discretion of the
Committee.

Article 4. Determination of Incentive Pool
- ------------------------------------------

    4.1  Incentive awards under the Plan shall be made from the Incentive Award
Pool established for each Plan Year. The Incentive Award Pool shall be an amount
equal to two (2) percent of BA Merchant Services, Inc.'s income for the Plan
Year before income tax expense, extraordinary items, amortized goodwill,
acquisition-related interest changes, and the cumulative effect of accounting
changes as specified in the Company's announcement of annual financial results
filed with the Securities and Exchange Commission.

    4.2  The Committee may, but need not, grant incentive awards up to the full
amount of the Incentive Award Pool.

    4.3  All officers are expected to maintain satisfactory operational and
financial controls for their respective areas of responsibility. As applicable,
Participants are expected to achieve satisfactory audits, both internal and
external, satisfactory credit examinations, to maintain proper financial records
and controls in accordance with applicable policy, and to respond promptly to
any control problems that might arise. The maintenance of and adherence to
internal controls is a key factor in evaluation of performance. If the
Participant fails to satisfactorily meet the requirements described above, the
Committee and CEO, in their sole judgment, may grant a lesser award or make no
award to a Participant in view of such failure.
<PAGE>
 
Article 5. Determination of Awards for Senior Officers
- ------------------------------------------------------
    
    5.1  The CEO shall establish a target award for each Senior Officer who is a
Participant as soon as practicable after the beginning of the Plan Year. The CEO
shall advise the Committee of the target award for each Participant. No
Participant's annual incentive award shall exceed $1,000,000.

    5.2  The Committee may, in its sole discretion, and as appropriate for tax
reasons, allocate a percentage of the Incentive Award Pool to a Senior Officer
who is a Participant for the Plan Year. The allocation shall be made prior to
January 31, 1997 and prior to January 1 of each subsequent Plan Year.

    5.3  After the end of the Plan Year, each Participant's performance shall be
assessed by the CEO who shall make an award recommendation to the Committee for
the Participant. For Participants with preallocated percentages in the Incentive
Award Pool, the CEO's designee shall calculate the nominal value of each
Participant's allocated percentage of the Incentive Award Pool.

    5.4  The designation of annual award recipients and the amount of individual
awards shall be in sole discretion of the Committee following receipt of
recommendations from the CEO. In determining awards, the Committee may follow
the award recommendation by the CEO or may make a lesser or greater award,
taking into account the Participant's overall contribution to the Company for
the Plan Year, the corporate performance of BA Merchant Services, Inc. for the
Plan Year, and such other criteria as the Committee may determine to promote the
purposes of the Plan in an individual case. For Participants with preallocated
percentages of the Incentive Award Pool, the Committee may use its discretion
only to reduce an incentive award below the nominal value of a Participant's
allocated percentage of the Incentive Award Pool.

Article 6. Payment and Deferral
- -------------------------------
    6.1  Incentive awards granted by the Committee, less applicable withholding
taxes, shall be paid in cash as soon as reasonably possible after being awarded.

    6.2  The Committee may permit or require a Participant to defer such
Participant's receipt of the payment of cash that would otherwise be due to such
Participant. If any such deferral election is required or permitted, the
Committee shall, in its sole discretion, establish rules and procedures for such
payment deferrals.
<PAGE>
 
Article 7. Other Provisions
- ---------------------------

    7.1  The Board of Directors of BA Merchant Services, Inc. reserves the right
to modify, suspend or terminate this Plan at any time.

    7.2  The Committee and CEO shall each have the power to construe and
interpret the Plan. Any decision arising out of or in connection with the
construction, interpretation and administration of the Plan shall lie within the
Committee's absolute discretion and shall be final and binding on all parties.

    7.3  The designation of an officer as a Participant or the grant of an award
to an officer shall not give such officer any right to be retained in the employ
of the Company and the ability of the Company to dismiss or discharge the
officer is specifically reserved.

    7.4  No Participant shall have the right to alienate, assign, encumber,
hypothecate or pledge his or her interest in any award under the Plan,
voluntarily or involuntarily, prior to payment and any attempt to dispose of any
such interest shall be void. Notwithstanding the preceding sentence, the Company
shall have the right to offset from an unpaid or deferred award any amounts due
and owing from the Participant to the extent permitted by law. The Company shall
not be required to segregate physically any cash or to establish any separate
account or accounts to fund any awards made or to be made under the Plan.

    7.5  This document is a complete statement of the Plan and as of the date
below supersedes all prior plans, proposals, representations, promises and
inducements, written or oral, relating to its subject matter. The Company shall
not be bound by or liable to any person for any representation, promise or
inducement made by any person which is not embodied in this document or in any
authorized written amendment to the Plan.

    7.6  The Plan shall be construed and enforced in accordance with Delaware
law.

their tender to satisfy the Option Price), or (c) by a combination of (a) and
(b).

    The Committee also may allow cashless exercise as permitted under Federal
Reserve Board's Regulation T, subject to applicable securities law restrictions,
or by any other means which the Committee determines to be consistent with the

shall deliver to the Participant, in the Participant's name, Share certificates
in an appropriate amount based upon the number of Shares purchased under the

restrictions on any Shares acquired pursuant to the exercise of an Option

exercise the Option following termination of the Participant's employment with

employment.

     (a) Incentive Stock Options. No ISO granted under the Plan may be sold,
         ------------------------

    7.1. Grant of SARs. Subject to the terms and conditions of the Plan, SARs
    ------------------
may be granted to Participants at any time and from time to time as shall be
determined by the Committee. The Committee may grant Freestanding SARs, Tandem

    The Committee shall have complete discretion in determining the number of
SARs granted to each Participant (subject to Article 4 herein) and, consistent
with the provisions of the Plan, in determining the terms and conditions
pertaining to such SARs.

    The grant price of a Freestanding SAR shall equal the Fair Market Value of a
Share on the date of grant of the SAR. The grant price of Tandem SARs shall
equal the Option Price of the related Option.

    7.2. Exercise of Tandem SARs. Tandem SARs may be exercised for all or part
    ----------------------------
of the Shares subject to the related Option upon the surrender of the right to
exercise the equivalent portion of the related Option. A Tandem SAR may be
exercised only with respect to the Shares for which its related Option is then
exercisable.

    Notwithstanding any other provision of this Plan to the contrary, with
respect to a Tandem SAR granted in connection with an ISO: (i) the Tandem SAR
will expire no later than the expiration of the underlying ISO; (ii) the value
of the payout with respect to the Tandem SAR may be for no more than one hundred
percent (100%) of the difference between the Option Price of the underlying ISO
and the Fair Market Value of the Shares subject to the underlying ISO at the
time the Tandem SAR is exercised; and (iii) the Tandem SAR may be exercised only
when the Fair Market Value of the Shares subject to the ISO exceeds the Option
Price of the ISO.

    ----------------------------------
whatever terms and conditions the Committee, in its sole discretion, imposes

    -----------------
determined by the Committee, in its sole discretion; provided, however, that
such term shall not exceed ten (10) years.

    7.6. Payment of SAR Amount. Upon exercise of an SAR, a Participant shall be
    --------------------------
entitled to receive payment from the Company in an amount determined by
multiplying:

     (a) The difference between the Fair Market Value of a Share on the date of
         exercise over the grant price; by

     (b) The number of Shares with respect to which the SAR is exercised.

    At the discretion of the Committee, the payment upon SAR exercise may be in
cash, in Shares of equivalent value, or in some combination thereof.

    7.7. Termination of Employment. Each SAR Award Agreement shall set forth the
    ------------------------------
extent to which the Participant shall have the right to exercise the SAR
following termination of the Participant's employment with the Company and/or
its subsidiaries. Such provisions shall be determined in the sole discretion of
the Committee, shall be included in the Award Agreement entered into with
Participants, need not be uniform among all SARs issued pursuant to the Plan,
and may reflect distinctions based on the reasons for termination of employment.

    7.8. Nontransferability of SARs. Except as otherwise provided in a
    -------------------------------
Participant's Award Agreement, no SAR granted under the Plan may be sold,
transferred, pledged, assigned, or otherwise alienated or hypothecated, other

    8.1. Grant of Restricted Stock. Subject to the terms and provisions of the
    ------------------------------
Plan, the Committee, at any time and from time to time, may grant Shares of
Restricted Stock to Participants in such amounts as the Committee shall
determine.

    8.2. Restricted Stock Agreement. Each Restricted Stock grant shall be
    -------------------------------
evidenced by a Restricted Stock Award Agreement that shall specify the Period(s)
of Restriction, the number of Shares of Restricted Stock granted, and such other
provisions as the Committee shall determine.
<PAGE>
 
    8.3. Transferability. Except as provided in this Article 8, the Shares of
    --------------------
Restricted Stock granted herein may not be sold, transferred, pledged, assigned,
or otherwise alienated or hypothecated, other than by will, by the laws of
descent and distribution, or pursuant to a qualified domestic relations order,
until the end of the applicable Period of Restriction established by the
Committee and specified in the Restricted Stock Award Agreement, or upon earlier
satisfaction of any other conditions, as specified by the Committee in its sole
discretion and set forth in the Restricted Stock Award Agreement. All rights
with respect to the Restricted Stock granted to a Participant under the Plan
shall be available during his or her lifetime only to such Participant.

    8.4. Other Restrictions. Subject to Article 10 herein, the Committee shall
    -----------------------
impose such other conditions and/or restrictions on any Shares of Restricted
Stock granted pursuant to the Plan as it may deem advisable including, without
limitation, a requirement that Participants pay a stipulated purchase price for
each Share of Restricted Stock, restrictions based upon the achievement of
specific performance goals (Company-wide, divisional, and/or individual), time-
based restrictions on vesting following the attainment of the performance goals,
and/or restrictions under applicable federal or state securities laws.

    The Company shall retain the certificates representing Shares of Restricted
Stock in the Company's possession until such time as all conditions and/or
restrictions applicable to such Shares have been satisfied.

    Except as otherwise provided in this Article 8, Shares of Restricted Stock
covered by each Restricted Stock grant made under the Plan shall become freely
transferable by the Participant after the last day of the applicable Period of
Restriction.

    8.5. Voting Rights. During the Period of Restriction, Participants holding
    ------------------
Shares of Restricted Stock granted hereunder may exercise full voting rights
with respect to those Shares.

    8.6. Dividends and Other Distributions. During the Period of Restriction,
    --------------------------------------
Participants holding Shares of Restricted Stock granted hereunder may be
credited with regular cash dividends paid with respect to the underlying Shares
while they are so held. The Committee may apply any restrictions to the
dividends that the Committee deems appropriate. Without limiting the generality
of the preceding sentence, if the grant or vesting of Restricted Shares granted
to a Named Executive Officer is designed to comply with the requirements of the
Performance-Based Exception, the Committee may apply any restrictions it deems
appropriate to the payment of dividends declared with respect to such Restricted
Shares, such that the dividends and/or the Restricted Shares maintain
eligibility for the Performance-Based Exception.
<PAGE>
 
    8.7. Termination of Employment. Each Restricted Stock Award Agreement shall
    ------------------------------
set forth the extent to which the Participant shall have the right to receive
unvested Restricted Shares following termination of the Participant's employment
with the Company. Such provisions shall be determined in the sole discretion of
the Committee, shall be included in the Award Agreement entered into with each
Participant, need not be uniform among all Shares of Restricted Stock issued
pursuant to the Plan, and may reflect distinctions based on the reasons for
termination of employment; provided, however that, except in the cases of
terminations by reason of death or Disability, the vesting of Shares of
Restricted Stock which qualify for the Performance-Based Exception and which are
held by Named Executive Officers shall occur at the time they otherwise would
have, but for the employment termination.

Article 9. Performance Units and Performance Shares
- ---------------------------------------------------

    9.1. Grant of Performance Units/Shares. Subject to the terms of the Plan,
    --------------------------------------
Performance Units and/or Performance Shares may be granted to Participants in
such amounts and upon such terms, and at any time and from time to time, as
shall be determined by the Committee.

    9.2. Value of Performance Units/Shares. Each Performance Unit shall have an
    --------------------------------------
initial value that is established by the Committee at the time of grant. Each
Performance Share shall have an initial value equal to the Fair Market Value of
a Share on the date of grant. The Committee shall set performance goals in its
discretion which, depending on the extent to which they are met, will determine
the number and/or value of Performance Units/Shares that will be paid out to the
Participant. For purposes of this Article 9, the time period during which the
performance goals must be met shall be called a "Performance Period."

    9.3. Earning of Performance Units/Shares. Subject to the terms of this Plan,
    ----------------------------------------
after the applicable Performance Period has ended, the holder of Performance
Units/Shares shall be entitled to receive payout on the number and value of
Performance Units/Shares earned by the Participant over the Performance Period,
to be determined as a function of the extent to which the corresponding
performance goals have been achieved.

    9.4. Form and Timing of Payment of Performance Units/ Shares. Payment of
    ------------------------------------------------------------
earned Performance Units/Shares shall be made in a single lump sum following the
close of the applicable Performance Period. Subject to the terms of this Plan,
the Committee, in its sole discretion, may pay earned Performance Units/Shares
in the form of cash or in Shares (or in a combination thereof) which have an
aggregate Fair Market Value equal to the value of the earned Performance
Units/Shares at the close of the applicable Performance Period. Such Shares may
be granted subject to any restrictions deemed appropriate by the Committee.
<PAGE>
 
    At the discretion of the Committee, Participants may be entitled to receive
any dividends declared with respect to Shares which have been earned in
connection with grants of Performance Units and/or Performance Shares which have
been earned, but not yet distributed to Participants (such dividends shall be
subject to the same accrual, forfeiture, and payout restrictions as apply to
dividends earned with respect to Shares of Restricted Stock, as set forth in
Section 8.6 herein). In addition, Participants may, at the discretion of the
Committee, be entitled to exercise their voting rights with respect to such
Shares.

    9.5. Termination of Employment Due to Death, Disability, or Retirement.
    ----------------------------------------------------------------------
Unless determined otherwise by the Committee and set forth in the Participant's
Award Agreement, in the event the employment of a Participant is terminated by
reason of death, Disability, or Retirement during a Performance Period, the
Participant shall receive a payout of the Performance Units/Shares which is
prorated, as specified by the Committee in its discretion.

    Payment of earned Performance Units/Shares shall be made at a time specified
by the Committee in its sole discretion and set forth in the Participant's Award
Agreement. Notwithstanding the foregoing, with respect to Named Executive
Officers who retire during a Performance Period, payments shall be made at the
same time as payments are made to Participants who did not terminate employment
during the applicable Performance Period.

    9.6. Termination of Employment for Other Reasons. In the event that a
    ------------------------------------------------
Participant's employment terminates for any reason other than those reasons set
forth in Section 9.5 herein, all Performance Units/Shares shall be forfeited by
the Participant to the Company unless determined otherwise by the Committee, as
set forth in the Participant's Award Agreement.

    9.7. Nontransferability. Except as otherwise provided in a Participant's
    -----------------------
Award Agreement, Performance Units/Shares may not be sold, transferred, pledged,
assigned, or otherwise alienated or hypothecated, other than by will, by the
laws of descent and distribution, or pursuant to a qualified domestic relations
order. Further, except as otherwise provided in a Participant's Award Agreement,
a Participant's rights under the Plan shall be exercisable during the
Participant's lifetime only by the Participant or the Participant's legal
representative.

Article 10. Performance Measures
- --------------------------------

    Unless and until the Committee proposes for shareholder vote and
shareholders approve a change in the general performance measures set forth in
this Article 10, the attainment of which may determine the degree of payout
and/or vesting with respect to Awards to Named Executive Officers which are
designed to qualify for the Performance-Based Exception, the performance
measure(s) to be used for purposes of such grants shall be chosen by the
<PAGE>
 
Committee from among the following: revenues, profits, economic profit, net
income (either before or after taxes), operating expense reductions, share
price, earnings per share, total shareholder return, return on assets, return on
equity, return on gross sales, operating income, return on capital or
investments or economic value added.

    The Committee shall have the discretion to adjust the determinations of the
degree of attainment of the preestablished performance goals; provided, however,
that Awards which are designed to qualify for the Performance-Based Exception,
and which are held by Named Executive Officers, may not be adjusted upward (the
Committee shall retain the discretion to adjust such Awards downward).

    In the event that applicable tax and/or securities laws change to permit
Committee discretion to alter the governing performance measures without
obtaining shareholder approval of such changes, the Committee shall have sole
discretion to make such changes without obtaining shareholder approval. In
addition, in the event that the Committee determines that it is advisable to
grant Awards which shall not qualify for the Performance-Based Exception, the
Committee may make such grants without satisfying the requirements of Code
Section 162(m).

Article 11. Beneficiary Designation
- -----------------------------------

    Each Participant under the Plan may, from time to time, name any beneficiary
or beneficiaries (who may be named contingently or successively) to whom any
benefit under the Plan is to be paid in case of his or her death (and/or who may
exercise the Participant's vested Options following his or her death). Each
designation shall revoke all prior designations by the same Participant, shall
be in a form prescribed by the Company, and will be effective only when filed by
the Participant in writing with the Company during the Participant's lifetime.
In the absence of any such designation, benefits remaining unpaid at the
Participant's death shall be paid to the Participant's estate (and, subject to
the terms and provisions of the Plan, any unexercised vested Options may be
exercised by the administrator or executor of the Participant's estate).

Article 12. Deferrals
- ---------------------

    The Committee may permit or require a Participant to defer such
Participant's receipt of the payment of cash or the delivery of Shares that
would otherwise be due to such Participant by virtue of the exercise of an
Option or SAR, the lapse or waiver of restrictions with respect to Restricted
Stock, or the satisfaction of any requirements or goals with respect to
Performance Units/Shares. If any such deferral election is required or
permitted, the Committee shall, in its sole discretion, establish rules and
procedures for such payment deferrals.
<PAGE>
 
Article 13. Rights of Employees
- -------------------------------

    13.1. Employment. Nothing in the Plan shall interfere with or limit in any
    ----------------
way the right of the Company to terminate any Participant's employment at any
time and for any reason, nor confer upon any Participant any right to continue
in the employ of the Company.

    13.2. Participation. No Employee shall have the right to be selected to
    -------------------
receive an Award under this Plan, or, having been so selected, to be selected to
receive a future Award.

Article 14. Amendment, Modification, and Termination
- ----------------------------------------------------

    14.1. Amendment, Modification, and Termination. The Board may at any time
    ----------------------------------------------
and from time to time, alter, amend, suspend or terminate the Plan in whole or
in part.

    14.2. Adjustment of Awards Upon the Occurrence of Certain Unusual or
    --------------------------------------------------------------------
Nonrecurring Events. The Committee may make adjustments in the terms and
- -------------------
conditions of, and the criteria included in, Awards in recognition of unusual or
nonrecurring events (including, without limitation, the events described in
Section 4.2 hereof) affecting the Company or the financial statements of the
Company or of changes in applicable laws, regulations, or accounting principles,
whenever the Committee determines that such adjustments are appropriate in order
to prevent dilution or enlargement of the benefits or potential benefits
intended to be made available under the Plan; provided that no such adjustment
shall be authorized to the extent that such authority would be inconsistent with
the Plan's meeting the requirements of Section 162(m) of the Code, as from time
to time amended.

    14.3. Awards Previously Granted. No termination, amendment, or modification
    -------------------------------
of the Plan shall adversely affect in any material way any Award previously
granted under the Plan, without the written consent of the Participant holding
such Award.

    14.4. Compliance with Code Section 162(m). At all times when Code 
    -----------------------------------------
Section 162(m) is applicable, all Awards granted under this Plan shall comply
with the requirements of Code Section 162(m); provided, however, that in the
event the Committee determines that such compliance is not desired with respect
to any Award or Awards available for grant under the Plan, then compliance with
Code Section 162(m) will not be required. In addition, in the event that changes
are made to Code Section 162(m) to permit greater flexibility with respect to
any Award or Awards available under the Plan, the Committee may, subject to this
Article 14, make any adjustments it deems appropriate.
<PAGE>
 
Article 15. Withholding
- -----------------------

    15.1. Tax Withholding. The Company shall have the power and the right to
    ---------------------
deduct or withhold, or require a Participant to remit to the Company, an amount
sufficient to satisfy Federal, state, and local taxes, domestic or foreign,
required by law or regulation to be withheld or deducted with respect to any
taxable event arising as a result of this Plan.

    15.2. Share Withholding. With respect to withholding required upon the
    -----------------------
exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock,
or upon any other taxable event arising as a result of Awards granted hereunder,
Participants may elect, subject to the approval of the Committee, to satisfy the
withholding requirement, in whole or in part, by having the Company withhold
Shares having a Fair Market Value on the date the tax is to be determined equal
to the minimum statutory total tax which could be imposed on the transaction.
All such elections shall be irrevocable, made in writing, signed by the
Participant, and shall be subject to any restrictions or limitations that the
Committee, in its sole discretion, deems appropriate.

Article 16. Indemnification
- ---------------------------

    Each person who is or shall have been a member of the Committee, or of the
Board, shall be indemnified and held harmless by the Company against and from
any loss, cost, liability, or expense that may be imposed upon or reasonably
incurred by him or her in connection with or resulting from any claim, action,
suit, or proceeding to which he or she may be a party or in which he or she may
be involved by reason of any action taken or failure to act under the Plan and
against and from any and all amounts paid by him or her in settlement thereof,
with the Company's approval, or paid by him or her in satisfaction of any
judgement in any such action, suit, or proceeding against him or her, provided
he or she shall give the Company an opportunity, at its own expense, to handle
and defend the same before he or she undertakes to handle and defend it on his
or her own behalf. The foregoing right of indemnification shall not be exclusive
of any other rights of indemnification to which such persons may be entitled
under the Company's Articles of Incorporation or Bylaws, as a matter of law, or
otherwise, or any power that the Company may have to indemnify them or hold them
harmless.

Article 17. Successors
- ----------------------

    All obligations of the Company under the Plan with respect to Awards granted
hereunder shall be binding on any successor to the Company, whether the
existence of such successor is the result of a direct or indirect purchase,
merger, consolidation, or otherwise, of all or substantially all of the business
and/or assets of the Company.

          G.  Allocation of Opportunities.  In consideration of the transactions
              ---------------------------                                       
contemplated by the Related Agreements and to preserve and enhance the goodwill
of the assets and business transferred to BAMSI, BAC is willing to enter into
this Agreement

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, and in consideration of their
mutual promises and obligations herein contained, intending to be legally bound,
the parties do hereby agree as follows:


                            ARTICLE 1 - DEFINITIONS

          1.1  "Affiliate" means any person which directly or indirectly
controls, is controlled by, or is under common control with, BAC.  A person is
regarded in control of another person if it owns, or directly or indirectly
controls, at least 50% of the voting stock or other ownership interest of the
other person, or if it directly or indirectly possesses the power to direct or
cause the direction of the management and policies of the other person by any
means whatsoever; provided however that, for the purposes of this Agreement,
BAMSI shall not be an Affiliate of BAC.

          1.2  "BAMSI Independent Directors" means the directors of BAMSI who
are not employees of BAMSI or BAC or an Affiliate of BAC.

          1.3  "Base Business" means payment processing for merchants to the
extent the payments arise from the use of credit, charge or debit cards for the
purchase of goods or services and are authorized through an electronic medium
originating at the point of sale.

          1.4  "Fair Market Value" means the value determined as such by an
independent firm mutually selected by BAC and the BAMSI Independent Directors.


              ARTICLE 2 - COMPETITION AND CORPORATE OPPORTUNITIES

          2.1  Noncompetition by BAC or Affiliates.  In consideration of the
               -----------------------------------                          
transactions contemplated by the Related Agreements and to preserve and enhance
the goodwill of the assets and business transferred to BAMSI, BAC agrees that
for as long as the Marketing Agreement continues in effect, neither BAC nor any
Affiliate will compete with BAMSI in the Base Business in the countries set
forth in the next succeeding sentence of this Section 2.1, subject to the
exceptions set forth in Section 2.2.  BAC agrees, subject to the exceptions set
forth in Section 2.2, that the geographic scope of this covenant not to compete
shall be the United States and the following countries upon the transfer of
BAC's Base Business in

                                      -2-      Corporate Opportunities Agreement

                                         
<PAGE>
 
each such country to BAMSI: Taiwan, the Philippines, Thailand, South Korea,
India, Indonesia, Vietnam and The Peoples Republic of China (each, an
"Additional Asian Country").  The parties hereto acknowledge and agree that,
notwithstanding the foregoing sentence of this Section 2.1, nothing in this
Agreement shall obligate BAC to (a) pursue any approvals in any Additional Asian
Country on other than commercially reasonable terms not involving the payment of
money, or (b) pursue, expand or develop a Base Business in any Additional Asian
Country.  Without limiting the generality of the foregoing sentence, each of the
counties in the State of California shall be within the scope of this covenant
not to compete, it being the intent of the parties to comply in all respects
with the provisions of Section 16601 of the California Business & Professions
Code.

          2.2  Exceptions to Noncompetition by BAC or Affiliates.  The
               -------------------------------------------------      
restrictions contained in Section 2.1 shall not apply to the Base Businesses
described in subsections (a), (b), and (c) of this Section 2.2:

          (a)  Subject to subsections (b), (c) and (d) of this Section 2.2, the
independent pursuit and acquisition (as opposed to the de novo commencement) by
BAC or any Affiliate of a Base Business.

          (b)  Any corporation, limited liability company, partnership or other
entity (or all or substantially all of the assets of such entity) conducting a
Base Business acquired directly or indirectly by BAC or an Affiliate (an
"Acquired Base Business") that has annual net merchant fee revenue of less than
10% of BAMSI's annual net merchant fee revenue.  For purposes of the preceding
sentence, such annual net merchant fee revenue shall be determined with
reference to the fiscal year of each such entity most recently ended.  If such
an Acquired Base Business with annual net merchant fee revenue of less than 10%
of BAMSI's annual net merchant fee revenue shall experience net revenue growth
such that its annual net merchant fee revenue shall equal or exceed 10% of
BAMSI's annual net merchant fee revenue for any year, then BAC shall cause such
Acquired Base Business to be offered to BAMSI for purchase at Fair Market Value.
If any such Acquired Base Business shall be combined with or a part of a
corporation, limited liability company, partnership or other entity conducting a
business other than a Base Business, then BAC shall be obligated only to offer
the portion of such business which conducts the Base Business to BAMSI.  Any
such offer shall be made to BAMSI no later than the end of the first fiscal
quarter of the year immediately following the first fiscal year for which the
determination of such annual net merchant fee revenue shall have been made, and
BAMSI shall exercise its right to acquire such Acquired Base Business within
three months after being so offered such business or BAC or any Affiliate shall
thereafter be free to conduct such business irrespective of the terms and
provisions of this Agreement.  The determination of BAMSI to acquire or not
acquire any such Acquired Base Business shall be made by the BAMSI Independent
Directors.

          (c)  Any other Acquired Base Business not covered by subsection (b)
where BAMSI has been offered by BAC or an Affiliate the right to acquire such
Acquired Base Business at Fair Market Value and the BAMSI Independent Directors
shall not have determined that BAMSI shall so acquire such business.  BAMSI
shall be offered the right to

                                      -3-      Corporate Opportunities Agreement

                                         
<PAGE>
 
so acquire such Acquired Base Business within six months after the acquisition
thereof by BAC or an Affiliate and the BAMSI Independent Directors must
determine that BAMSI shall exercise such right to acquire such business within
three months after being so offered such business or BAC or any Affiliate shall
thereafter be free to continue to conduct such business irrespective of the
provisions of this Agreement.

          (d)  Notwithstanding the foregoing provisions of this Section 2.2, BAC
agrees that, during the term of this Agreement, it shall not, and that it shall
cause its Affiliates to not, acquire any corporation, limited liability company,
partnership or other entity (or all or substantially all of the assets of any
such entity) conducting a Base Business, where (i) the Base Business of such
entity is conducted primarily in the United States or an Additional Asian
Country and (ii) the Base Business of such entity, for the fiscal year of such
entity most recently ended, generated more than 66 2/3% of the total revenues of
such entity determined on a consolidated basis; provided, however, that the
foregoing provisions of this subsection (d) shall not be deemed to prevent any
merger, consolidation, joint venture, partnership or other business combination
between BAMSI (or any subsidiary thereof) and any other such entity or the
acquisition of the assets of any such other entity by BAMSI.

          2.3  Allocation of Corporate Opportunities.  As
               ------------------------------------- 
to any corporate opportunity outside the scope of the Base Business which may be
presented to BAMSI or BAC or any Affiliate and which could reasonably be
expected to be related to the Base Business, BAC shall be entitled to determine
the allocation thereof based upon its evaluation of the best interests of the
BAC stockholders under the circumstances.

          2.4  BAC Determination Binding.  The good faith determination of BAC
               -------------------------                                      
as to the scope of the Base Business or the applicability of any of the
exceptions provided for in Section 2.2 or the allocation of any corporate
opportunities by BAC pursuant to Section 2.3, shall be conclusive and binding
for all purposes.


                        ARTICLE 3 - TERM AND TERMINATION

          3.1  Term.  The term of this Agreement shall commence on the

Effective Date and shall continue for five years thereafter, unless terminated
earlier pursuant to Section 3.2 or extended by the mutual agreement of the
parties.

          3.2  Termination.  BAC shall have the right to terminate this
               -----------                                             
Agreement upon the occurrence of any of the following events:

          (a)  A material breach of this Agreement by BAMSI or any of its
Affiliates that is not cured within 30 days after receipt of written notice of
such breach from BAC; or

          (b)  A material breach of the License Agreement or the Marketing
Agreement by BAMSI which is not cured within 30 days after receipt of written
notice from BAC; or

                                      -4-      Corporate Opportunities Agreement

                                         
<PAGE>
 
          (c)  BAC and its Affiliates beneficially own shares representing less
than a majority of the voting power of the outstanding common stock of BAMSI.


                       ARTICLE 4 - RESOLUTION OF DISPUTES

          4.1  Arbitration.  Any dispute, controversy or claim between the Bank
               -----------

instruments relating hereto or delivered in connection herewith, will be

State of Delaware, with its principal executive offices located in San

such activities are so permissible, it shall so notify BAMSI and BAMSI may
engage in such activities, subject to regulatory approval, if deemed necessary
by BANW.  Notwithstanding anything to the contrary contained herein, if BANW, or
any regulatory agency with authority over BANW, the Bank or BAMSI, determines
that such new activities are not permissible for national banks, at the sole

debits or credits effected by BAMSI with respect to Bank's Depository Account
for any amounts due to or due from Bank, Bank shall notify BAMSI in writing
within 45 days after such debit or credit is effected.  If Bank fails to notify
BAMSI within such timeframe, BAMSI shall not be responsible for investigating or
effecting any required adjustments, absent BAMSI's gross negligence or their
employees' fraud or misconduct.  If Bank notifies BAMSI after such time period
that it believes adjustments are needed, BAMSI may, in their discretion, assist
Bank in investigating whether any adjustments are appropriate and whether any
amounts are due to or from other parties, but BAMSI shall not have any liability
to effect any such adjustments absent BAMSI's gross negligence or their
employees' fraud or misconduct.  Any voluntary efforts by BAMSI to assist Bank
in investigating such matters shall not create any obligation to continue such
investigation or assist with any investigation in response to any future notices

the fees set forth in Attachment A.  BAMSI, at its option, may elect to debit
the Bank's Depository Account on a less frequent basis than daily for certain
fees.  Any such election at any time by BAMSI to debit the Bank's Depository
Account for certain BAMSI fees on a less frequent basis than daily, will not be
taken or held as a waiver of BAMSI's rights to debit for fees on a daily basis
at any time thereafter.

          (h)   The fees set forth in Attachment A shall be subject to
adjustments to accommodate the imposition of new or amended fees by third
parties including additional unforeseen processing costs arising from any

increase disproportionally to increases in Bank portfolio dimensions, BAMSI
reserves the right to request corrective action from the bank to correct the
situation or charge additional fees to compensate for increased volume.

          (k)   From time to time, Bank will provide to BAMSI evidence of its
proper and timely payment of any applicable taxes on services or equipment

such taxes.

accounts held at Bank.  Bank acknowledges that all accounts of Merchants at Bank
will be subject to security interests in favor of BAMSI, except to the extent
explicitly excluded in BAMSI's Agreements with the Merchants.  After BAMSI
notifies Bank that BAMSI wants to block or restrict access to the accounts of
any Merchant, Bank will cooperate with BAMSI to place funds in accounts subject
to BAMSI's security interest under the control of BAMSI.  If a Merchant is also
in default on an obligation to Bank for which the Merchant's deposit account at
Bank serve as collateral, Bank will share the funds in the Merchant's deposit
accounts with BAMSI pro rata.

debits or credits effected by BAMSI with respect to Bank's Depository Account

within 45 days after such debit or credit is effected.  If Bank fails to notify
BAMSI within such timeframe, BAMSI shall not be responsible for investigating or
effecting any required adjustments, absent BAMSI's gross negligence or their
employees' fraud or misconduct.  If Bank notifies BAMSI after such time period
that it believes adjustments are needed, BAMSI may, in their discretion, assist
Bank in investigating whether any adjustments are appropriate and whether any
amounts are due to or from other parties, but BAMSI shall not have any liability
to effect any such adjustments absent BAMSI's gross negligence or their
employees' fraud or misconduct.  Any voluntary efforts by BAMSI to assist Bank
in investigating such matters shall not create any obligation to continue such
investigation or assist with any investigation in response to any future notices
of possible adjustments that are not timely submitted.

fees.  Any such election at any time by BAMSI to debit the Bank's Depository
Account for certain BAMSI fees on a less frequent basis than daily, will not be
taken or held as a waiver of BAMSI's rights to debit for fees on a daily basis
at any time thereafter.

       (h)    The fees set forth in Attachment A shall be subject to adjustments
to accommodate the imposition of new or amended fees by third parties including
additional unforeseen processing costs arising from any requirements imposed by

imposition of new or amended regulations declared by the Associations or
governmental requirements, and will be immediately effective upon the effective
date of such adjustment.

proper and timely payment of any applicable taxes on services or equipment

resale certificates and evidence of the jurisdictions in which it pays any such
taxes).  Bank assumes all liability for the proper and timely payment of any
such taxes.

accounts held at Bank.  Bank acknowledges that all accounts of Merchants at Bank
will be subject to security interests in favor of BAMSI, except to the extent
explicitly excluded in BAMSI's Agreements with the Merchants.  After BAMSI
notifies Bank that BAMSI wants to block or restrict access to the accounts of

BAMSI charged back to Bank.

terminated:

           (i)   With or without cause by either party upon 90 days' written
     notice to the other party.  Termination of this Agreement will not affect
     the obligations concerning any transactions occurring or amounts due before
     termination, or to Bank's obligations relating to security interests
     granted to BAMSI by Merchants in accounts at Bank;

           (ii)  If at any time during the term hereunder the practices
     hereunder are declared unlawful by federal or state authorities or by a
     judicial body, or

     upon any deadline imposed by MasterCard or Visa for complying with any
     Association Rule which precludes the continued performance by BAMSI or Bank
     of their obligations hereunder, any party may terminate this Agreement
     immediately.

           (iii) If any party shall materially default in the performance of its
     obligations hereunder and shall fail or refuse to remedy such default
     within 30 days after written notice, the other party or parties may
     terminate this Agreement on 7 days written notice.

           (iv)  At any time after the filing of any petition in bankruptcy or
     for reorganization or debt consolidation under the federal bankruptcy laws
     or receivership, or under any comparable law by or against a party hereto,
     or upon a party making an assignment of its assets for the benefit of
     creditors, or upon a party's application for the appointment of a receiver
     or trustee of a party's assets, or upon an involuntary petition in
     bankruptcy being filed against a party if such petition is not dismissed
     within 60 days after it is filed, or upon the initiation by governmental
     authorities of any receivership or assisted acquisition transaction, the
     other party or parties may terminate this Agreement.

           (v)   Bank may terminate this Agreement upon expiration or
     termination of the Corporate Opportunities Agreement, the Sponsorship
     Agreement, the License Agreement or the Marketing Agreement.

           (vi)  Bank may terminate this Agreement in the event BAC and its
     affiliates (other than BAMSI) beneficially own less than a majority of the
     voting power of the outstanding common stock of BAMSI.

     (b)   Upon termination of this Agreement, Bank will return to BAMSI or
destroy the Merchant Services material provided by BAMSI as BAMSI may request
(including without limitation, unused Merchant Agreements, applications and
advertising materials). Bank will also immediately remove all decals and signs
containing any of the card service marks, or the name or any service mark or
trademark of BAMSI, except to the extent permissible under another continuing
relationship with BAMSI.

     17.   Miscellaneous.

     (a)   Bank will allow BAMSI and Card Associations to examine, at reasonable
times, all records of Bank relating to this Agreement or Transaction Records of
Merchants.

     (b)   Bank and BAMSI may each enter into other agreements to provide
Merchant Services to any business, whether or not covered by this Agreement,
even though that business may have previously entered into a similar agreement
with Bank or BAMSI. Any change in the financial institution with which a
business has an agreement for Merchant Services will be the decision of the
business. Other provisions of this Agreement to the contrary notwithstanding,
BAMSI covenants and agrees that it will not actively solicit Merchant Services
