Dear Stockholder:
 
     You are cordially invited to attend a special meeting of stockholders of BA
Merchant Services, Inc. (the "Company"), to be held at Bank of America Center,
555 California Street, 8th Floor Conference Room, San Francisco, California, on
March 25, 1999, at 10:00 a.m., local time (the "Meeting"). A notice of the
Meeting, a proxy and a proxy statement containing information about the matters
to be acted upon are enclosed. Stockholders of record at the close of business
on February 17, 1999 (the "Record Date") will be entitled to vote at the Meeting
or any postponement or adjournment thereof.
 
     At the Meeting you will be asked to consider and vote upon a proposal to
approve and adopt an Agreement and Plan of Merger (the "Merger Agreement"),
dated as of December 22, 1998 among the Company, BankAmerica Corporation, a
Delaware corporation ("BankAmerica"), and BAMS Acquisition Corporation, a
Delaware corporation and a wholly owned subsidiary of BankAmerica ("Acquisition
Corp."), pursuant to which Acquisition Corp. will be merged with and into the
Company (the "Merger"). If the Merger Agreement is approved and adopted and the
Merger becomes effective, each share of Class A Common Stock, par value $.01 per
share, of the Company ("Class A Common Stock") outstanding immediately prior to
the Merger (except for shares as to which appraisal rights have been perfected
and shares held in the treasury of the Company) will be converted into the right
to receive $20.50 in cash, without interest thereon. Approval and adoption of
the Merger Agreement requires the affirmative vote of the holders of a majority
of the Company's outstanding shares of Class A Common Stock and Class B Common
Stock, par value $.01 per share ("Class B Common Stock"), voting as a single
class. As of the Record Date, BankAmerica, directly or indirectly, owned 100% of
the outstanding Class B Common Stock, which, on that date, represented
approximately 66.6% of the economic ownership of the Company and approximately
95.2% of the combined voting power of the Company. Therefore, BankAmerica has
sufficient voting power to approve and adopt the Merger Agreement, regardless of
the vote of any other stockholder. In the Merger Agreement, BankAmerica has
agreed to vote in favor of the Merger provided that the recommendation of the
Special Committee of the Company's Board of Directors (as defined below) with
respect to the Merger is not revoked, modified or qualified in a manner adverse
to BankAmerica. AS A RESULT OF THE VOTING POWER OF BANKAMERICA AND THE AGREEMENT
OF BANKAMERICA TO VOTE IN FAVOR OF THE MERGER, THE MERGER MAY BE APPROVED AT THE
MEETING REGARDLESS OF THE VOTE OF ANY OTHER STOCKHOLDER.
 
     Details of the proposed Merger and other important information are set
forth in the accompanying Proxy Statement, which you are urged to read
carefully.
 
     Your Board of Directors (of which four of the seven members are current or
former employees of BankAmerica or its affiliates) has voted unanimously to
approve the Merger in accordance with the recommendation of a special committee
of the Board of Directors consisting of three independent directors (the
"Special Committee"), none of whom is an employee of BankAmerica or its
affiliates or the Company. In making its recommendation, the Special Committee
carefully reviewed and considered the terms and conditions of the proposed
Merger as described in the enclosed Proxy Statement. In addition, the Special
Committee has received an opinion from its independent financial advisor, Credit
Suisse First Boston Corporation, that the consideration to be received in the
Merger by the Company's public stockholders is fair to such public stockholders
from a financial point of view.
 
     Based upon the unanimous recommendation of the Special Committee, your
Board of Directors, recommends that you vote FOR approval and adoption of the
Merger Agreement.
 
     Only holders of record of Class A Common Stock and Class B Common Stock at
the close of business on the Record Date will be entitled to notice of, and to
vote at, the Meeting.
 
     Whether or not you plan to attend the Meeting, please complete, sign and
date the accompanying proxy card and return it in the enclosed prepaid envelope.
If you attend the Meeting, you may revoke such proxy and vote in person if you
wish, even if you have previously returned your proxy card. Your prompt
attention to this matter and cooperation are greatly appreciated.
 
                                          Very truly yours,
 
                                          Sharif M. Bayyari
                                          President and Chief Executive Officer

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
 
                          TO BE HELD ON MARCH 25, 1999
                             ---------------------
 
To the Stockholders of BA Merchant Services, Inc.:
 
     A special meeting of the stockholders of BA Merchant Services, Inc., a
Delaware corporation (the "Company"), will be held at Bank of America Center,
555 California Street, 8th Floor Conference Room, San Francisco, California, on
March 25, 1999, at 10:00 a.m., local time (the "Meeting"), for the following
purposes:
 
          1. To consider and vote upon a proposal to approve and adopt an
     Agreement and Plan of Merger (the "Merger Agreement"), dated as of December
     22, 1998, among the Company, BankAmerica Corporation, a Delaware
     corporation ("BankAmerica") and BAMS Acquisition Corporation, a Delaware
     corporation ("Acquisition Corp."), pursuant to which, among other things:
     (i) Acquisition Corp., which is a wholly owned subsidiary of BankAmerica,
     will be merged with and into the Company (the "Merger"); (ii) each
     outstanding share of Class A Common Stock, par value $.01 per share, of the
     Company ("Class A Common Stock"), except shares as to which appraisal
     rights have been perfected and shares held in the treasury of the Company,
     will be converted into the right to receive in the Merger $20.50 in cash,
     without interest thereon; and (iii) each outstanding share of the Company's
     Class B Common Stock, par value $.01 per share ("Class B Common Stock"),
     (all of which are owned, directly or indirectly, by BankAmerica) will be
     converted into 100 shares of the common stock of the surviving corporation.
 
          2. To transact such other business as may be properly brought before
     the Meeting, or any adjournments or postponements thereof.
 
     The Board of Directors of the Company has fixed the close of business on
February 17, 1999 as the record date for the determination of the stockholders
entitled to notice of and to vote at the Meeting and any adjournment or
postponement thereof. Accordingly, only holders of record of Class A Common
Stock and Class B Common Stock at the close of business on such date shall be
entitled to notice of and to vote at the Meeting and any adjournment or
postponement thereof.
 
     Approval and adoption of the Merger Agreement will require the affirmative
vote of a majority of the outstanding shares of Class A Common Stock and Class B
Common Stock, voting as a single class. As of the record date, BankAmerica,
directly or indirectly, owned 100% of the outstanding Class B Common Stock,
which, on that date, represented approximately 66.6% of the economic ownership
of the Company and approximately 95.2% of the combined voting power of the
Company. Therefore, BankAmerica has sufficient voting power to approve and adopt
the Merger Agreement, regardless of the vote of any other stockholder. In the
Merger Agreement, BankAmerica has agreed to vote in favor of the Merger,
provided that the recommendation of the Special Committee with respect to the
Merger is not revoked, modified or qualified in a manner adverse to BankAmerica.
 
     Any stockholder of the Company has the right to dissent from the Merger and
to obtain the "fair value" of such stockholder's shares of Class A Common Stock,
provided that such stockholder perfects his or her appraisal rights in
accordance with Section 262 of the Delaware General Corporation Law. Please see
the discussion of appraisal rights in the accompanying Proxy Statement and
Section 262, a copy of which is attached as Annex III to the Proxy Statement.

Company) will be converted into the right to receive $20.50 in cash, without
interest thereon.
 
    As of the Record Date, BankAmerica, directly or indirectly, owned 100% of
the outstanding Class B Common Stock, which, on that date, represented
approximately 66.6% of the economic ownership of the Company and approximately
95.2% of the combined voting power of the Company.
 
    On February 17, 1999, the last reported sale price for the Class A Common
Stock on the New York Stock Exchange ("NYSE") was $         . On October 22,
1998, the date immediately prior to the initial announcement of the proposal by

the Secretary of the Company an instrument of revocation or a duly executed
proxy bearing a later date or by attending the Meeting and voting in person.
Appearance at the Meeting by a stockholder who has given a valid proxy will not,

represented by more than one properly executed proxy, the executed proxy bearing
the latest date will be voted at the Meeting. See "The Meeting -- Proxies."

                             business on February 17, 1999 (the "Record Date")
                             are entitled to notice of and to vote at the
                             Meeting. At such date there were outstanding
                                            shares of Class A Common Stock, each
                             of which will be entitled to one vote at the
                             Meeting, and 32,400,000 shares of Class B Common

                             class. See "The Meeting -- Voting at the Meeting;
                             Record Date; Quorum."
 
Purpose of the Meeting.....  The purpose of the Meeting is to consider and vote
                             upon a proposal to approve and adopt the Merger
                             Agreement. See "The Meeting -- Matters to be
                             Considered at the Meeting."
 
Votes Required.............  The approval and adoption of the Merger Agreement
                             by stockholders of the Company will require the
                             affirmative vote of the holders of a majority of
                             the outstanding shares of Class A Common Stock and
                             Class B Common Stock, voting as a single class.
 
                             As of the Record Date, BankAmerica, directly or
                             indirectly, owned 100% of the outstanding Class B
                             Common Stock (constituting approximately 66.6% of
                             the economic ownership of the Company and 95.2% of
                             the combined voting power of the Company).
                             Therefore, BankAmerica has sufficient voting power
                             to constitute a quorum and to approve all matters
                             to be considered at the Meeting, regardless of the
                             vote of any other stockholder. BankAmerica has
                             agreed to vote all shares of Common Stock over
                             which it has control for approval and adoption of
                             the Merger Agreement, provided that the
                             recommendation of the Special Committee with
                             respect to the Merger is not revoked, modified or
                             qualified in a manner adverse to BankAmerica. See
                             "The Meeting -- Voting at the Meeting; Record Date;
                             Quorum."

                             been perfected and any share of Class A Common
                             Stock held in the treasury of the Company, will be
                             converted into the right to receive $20.50 in cash,
                             without interest thereon.
 
                             Promptly after the Effective Time, the Company will
                             send to holders of Class A Common Stock a
                             transmittal letter containing instructions for the

                             Class A Common Stock. The transmittal letter will
                             set forth the procedure for surrendering such
                             certificates for exchange to ChaseMellon

                             (the "Exchange Agent"). In order to receive the
                             payment to which he or she is entitled, each
                             stockholder of the Class A Common Stock will be
                             required, following the Merger, to surrender his or

                             executed and properly completed transmittal letter
                             (and any other required documents), to the Exchange
                             Agent. Holders of Class A Common Stock should

                             letter. Stock certificates should not be sent with
                             the enclosed proxy card. After surrendering the
                             certificate(s), each stockholder of Class A Common
                             Stock will receive,

                             in exchange for such certificate(s), cash in an
                             amount equal to the product of the number of shares
                             of Class A Common Stock formerly represented by his
                             or her certificate(s) and $20.50. No interest will
                             be paid on the cash payable upon the surrender of
                             the Class A Common Stock certificates. See "The
                             Merger -- General."
 
                             Each issued and outstanding share of Class A Common
                             Stock as to which appraisal rights have been
                             perfected will be treated as described herein under
                             "The Merger -- Appraisal Rights."
 
                             Each share of Class A Common Stock and Class B
                             Common Stock issued and outstanding immediately
                             prior to the Effective Time and owned by
                             BankAmerica or its affiliates will be converted
                             into 100 shares of the common stock of the
                             Surviving Corporation.
 
                             Upon consummation of the Merger, the Company will
                             be a wholly owned subsidiary of Bank of America
                             National Trust and Savings Association (the "Bank"
                             or "Bank of America"), itself a wholly owned
                             subsidiary of BankAmerica, and the holders of Class
                             A Common Stock immediately prior to the Merger will
                             cease to have ownership interests in the Company or
                             rights as stockholders (other than statutory
                             appraisal rights, in the case of those stockholders
                             who perfect such rights under Delaware law). The
                             public stockholders will no longer benefit from any
                             increases in the value of the Company or any
                             payment of dividends on Class A Common Stock and
                             will no longer bear the risk of any decreases in
                             the value of the Company.

                             Board of Directors and of the Special Committee
                             with respect to the Merger, stockholders should be
                             aware that certain members of the Special Committee
                             and the Board of Directors may have certain
                             interests in the Merger that are in addition to or
                             different from the interests of stockholders of the
                             Company generally. The Board of Directors of the
                             Company and the Special Committee were aware of
                             these interests and considered them, along with
                             other matters, in approving and adopting the Merger
                             Agreement and the transactions contemplated
                             thereby. See "Special Factors -- Interests of
                             Certain Persons in the Merger."
 
Effective Time of the
Merger.....................  It is anticipated that the Merger will become
                             effective as promptly as practicable after
                             stockholder approval has been obtained, assuming
                             all other conditions to the Merger have been
                             satisfied or waived. The Merger will become
                             effective as of the date and time specified in a
                             certificate of merger to be filed with the
                             Secretary of State of the State of Delaware (such
                             date and time, the "Effective Time"). See "The
                             Merger -- General."

                             consummation of the Merger has become final and

                             modified in a manner adverse to BankAmerica or
                             qualified in a manner adverse to BankAmerica, its

                             interest thereon pursuant to the Delaware General

                             shares of Class A Common Stock pursuant to the
                             Merger will be a taxable transaction for federal
                             income tax purposes and may also be a taxable
                             transaction under applicable state, local, foreign
                             or other tax laws. Stockholders should consult
                             their tax advisor with respect to the tax
                             consequences of the Merger, including the

Accounting Treatment.......  The acquisition of the Company's public shares in
                             the Merger will be accounted for by BankAmerica as
                             a "purchase" under generally accepted accounting
                             principles. See "The Merger -- Accounting
                             Treatment."

                             Stock Plan (collectively, the "Stock Plans") shall
                             be canceled in exchange for a cash payment of an
                             amount equal to (i) the excess, if any, of (x) the
                             Merger Consideration per share over (y) the

Security Ownership of
  BankAmerica, Management
  and Certain Other
  Persons..................  As of February 17, 1999, BankAmerica, directly or
                             indirectly, was the beneficial owner of 32,400,000
                             shares of Class B Common Stock, representing 100%
                             of the outstanding Class B Common Stock and
                             approximately 95.2% of the combined voting power of
                             the outstanding Common Stock. As of February 17,
                             1999, the directors and officers of BankAmerica as
                             a group were beneficial owners of less than one
                             percent of the Class A Common Stock, and the
                             directors and officers of the Company as a group
                             were beneficial owners of approximately      % of
                             the Class A Common Stock (constituting less than
                             one percent of the combined voting power of the
                             outstanding Common Stock). See "Security Ownership
                             of Certain Beneficial Owners and Management."
 
Stockholder Litigation.....  Subsequent to the announcement by BankAmerica and
                             the Company on October 22, 1998, that BankAmerica
                             was offering to acquire through merger each
                             outstanding share of Class A Common Stock for
                             $15.50 per share in cash, three putative class
                             actions were filed in the Court of Chancery of the
                             State of Delaware. Each of these actions challenge
                             the terms of BankAmerica's initial proposal, name
                             as defendants certain present and former directors
                             of the Company, and allege that these individuals,
                             as well as BankAmerica, breached their fiduciary
                             duty to the public stockholders of the Company.
                             These actions seek to have the Merger enjoined or,
                             if it is consummated, to have it rescinded and to
                             recover unspecified damages, fees and expenses. On
                             December 22, 1998, counsel to BankAmerica, the
                             Company and the other defendants entered into a
                             Memorandum of Understanding with counsel to the
                             plaintiffs in such cases for the settlement
                             thereof, subject to court approval and certain
                             other conditions. See "The Merger -- Litigation."

(1) All data presented for the years ended December 31, 1997, 1996, 1995 and
    1994 include the historical results of the acquisitions by the Company in
    the second and third quarters of 1997 of BankAmerica's merchant processing
    business in Thailand, the Philippines and Taiwan and its merchant processing
    administrative office in Hong Kong (collectively, the "Asia Acquisitions").
    The acquisition of these entities has been accounted for as a reorganization
    of entities under common control. Prior to January 1,
 
                                       11

    1994, the Asian operations were fully integrated with the operations of
    BankAmerica in each of the respective countries. Certain amounts have been
    reclassified to conform with the current year presentation. Amounts
    reflected in this table may not foot due to rounding.
(2) On December 31, 1996, certain employees of the Company elected to exchange
    their employee stock options and restricted stock from BankAmerica for
    options and restricted stock of the Company. This employee stock exchange
    resulted in a one-time expense of $2.4 million.
(3) The earnings per common share amount has not been presented because it is
    the same as the diluted earnings per common share amount.
(4) Pro forma diluted earnings per common share for all periods presented has
    been calculated as if the initial offerings of Class A Common Stock had been
    completed on January 1, 1993, and 48.5 million shares (32.4 million shares
    of Class B Common Stock and 16.1 million shares of Class A Common Stock) had
    been outstanding for all periods presented.
(5) Pro forma earnings per share, as adjusted, assumes that the proceeds from
    the initial offerings were available from January 1, 1994 and were invested
    in short-term investments, and excludes the one-time expense related to the
    employee stock exchange ($2.4 million) and interest expense of $492,000 from
    the 1996 results.
(6) BankAmerica's equity interest represents cumulative historical net income of
    the Company adjusted for net cash transfers to and from BankAmerica. On
    December 3, 1996, BankAmerica exchanged its equity interest in the domestic
    operations of the Company for 30.2 million shares of Class B Common Stock.
    During the second and third quarters of 1997, BankAmerica exchanged its
    equity interest in certain Asian operations of the Company for 2.2 million
    shares of Class B Common Stock.

                                  THE MEETING
 
GENERAL
 
     This Proxy Statement is being furnished to holders of the Class A Common
Stock and the Class B Common Stock in connection with the solicitation of
proxies by the Board of Directors of the Company for use at the Meeting to be
held on March 25, 1999, at Bank of America Center, 555 California Street, 8th
Floor Conference Room, San Francisco, California, commencing at 10:00 a.m.,
local time, and at any adjournment or postponement thereof.
 
     This Proxy Statement, the enclosed Notice of Special Meeting of
Stockholders and the accompanying form of proxy are first being mailed to
stockholders of the Company on or about February   , 1999.
 
MATTERS TO BE CONSIDERED AT THE MEETING
 
     At the Meeting, holders of Common Stock will consider and vote upon a
proposal to approve and adopt the Merger Agreement, pursuant to which
Acquisition Corp. will be merged with and into the Company, with the Company
being the Surviving Corporation. Upon consummation of the Merger, each share of
Class A Common Stock (except for shares as to which appraisal rights have been
perfected and shares held in the treasury of the Company) will be converted into
the right to receive $20.50 in cash, without interest thereon (the "Merger
Consideration").
 
     BANKAMERICA, DIRECTLY OR INDIRECTLY, BENEFICIALLY OWNS AND HAS THE RIGHT TO
VOTE AT THE MEETING A SUFFICIENT NUMBER OF SHARES TO APPROVE AND ADOPT THE
MERGER AGREEMENT UNDER DELAWARE LAW WITHOUT THE APPROVAL OF ANY OTHER
STOCKHOLDER. BANKAMERICA HAS AGREED TO VOTE ALL SUCH SHARES IN FAVOR OF THE
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT, PROVIDED THAT THE RECOMMENDATION
OF THE SPECIAL COMMITTEE WITH RESPECT TO THE MERGER IS NOT REVOKED, MODIFIED OR
QUALIFIED. ACCORDINGLY, NO ACTION BY ANY OTHER STOCKHOLDER IS REQUIRED TO
APPROVE AND ADOPT THE MERGER AGREEMENT.
 
BOARD OF DIRECTORS RECOMMENDATION
 
     The Board of Directors of the Company (four of the seven being employees or
former employees of BankAmerica or its affiliates) unanimously approved and
adopted the Merger Agreement (in accordance with the unanimous recommendation of
the Special Committee) and the Board of Directors recommends that stockholders
of the Company vote FOR the approval and adoption of the Merger Agreement. For
further information see "Special Factors" and "The Merger" generally and
"Special Factors -- Reasons for the Merger; Recommendation of the Company's
Board of Directors and the Special Committee" specifically.
 
VOTING AT THE MEETING; RECORD DATE; QUORUM
 
     The Company has fixed February 17, 1999 as the Record Date for the
determination of the stockholders entitled to notice of and to vote at the
Meeting. Accordingly, only holders of record of Common Stock on the Record Date
will be entitled to notice of and to vote at the Meeting. As of February 17,
1999 there were                shares of Class A Common Stock (excluding
     shares held in the treasury of the Company) outstanding and entitled to
vote, none of which were held, directly or indirectly, by BankAmerica and all of
which were held, directly or indirectly, by approximately      holders of
record, and 32,400,000 shares of Class B Common Stock outstanding and entitled
to vote, all of which were held, directly or indirectly, by BankAmerica. Each
holder of record of Class A Common Stock on the Record Date is entitled to cast
one vote per share, and each holder of record of Class B Common Stock on the
Record Date is entitled to cast ten votes per share, on all matters properly
submitted for the vote of the Company's stockholders. The presence at the
Meeting, in person or by properly executed proxy, of the holders of a majority
of the shares of Common Stock entitled to vote is necessary to constitute a
quorum at the Meeting. Each properly executed proxy will be voted in accordance
with the instructions thereon; however, a properly executed proxy marked
                                       13
<PAGE>   18
 
"ABSTAIN," although counted for purposes of determining whether there is a
quorum at the Meeting, will not be voted.
 
     The approval and adoption of the Merger Agreement by stockholders of the
Company will require the affirmative vote of the holders of a majority of the
outstanding Class A Common Stock and the outstanding Class B Common Stock,
voting as a single class.
 
     As of February 17, 1999, BankAmerica was, directly or indirectly, the
beneficial owner of 100% of the outstanding Class B Common Stock, representing
approximately 66.6% of the economic ownership of the Company and 95.2% of the
combined voting power of the Company. BankAmerica has agreed to vote all shares
of the Common Stock over which it has voting control FOR approval and adoption
of the Merger Agreement, provided that the recommendation of the Special
Committee with respect to the Merger is not revoked, modified or qualified.
 
     UPON THE VOTE OF THE SHARES OF COMMON STOCK HELD BY BANKAMERICA IN
ACCORDANCE WITH ITS OBLIGATION AND INTENTIONS STATED ABOVE, BOTH THE QUORUM AND
VOTE REQUIRED AT THE MEETING FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT
WOULD BE SATISFIED.
 
PROXIES
 
     All shares of Common Stock represented at the Meeting by properly executed
proxies received prior to or at the Meeting, and not revoked, will be voted at
the Meeting in accordance with the instructions indicated on such proxies. If no
instructions are indicated, such proxies will be voted FOR approval and adoption
of the Merger Agreement.
 
     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by: (i) filing
with the Secretary of the Company, at or before the taking of the vote at the
Meeting, a written notice of revocation bearing a later date than the proxy;
(ii) duly executing a later dated proxy relating to the same shares and
delivering it to the Secretary of the Company before the taking of the vote at
the Meeting; or (iii) attending the Meeting and voting in person (although
attendance at the Meeting will not in and of itself constitute a revocation of a
proxy). Any written notice of revocation or subsequent proxy should be sent and
delivered to BA Merchant Services, Inc., c/o Bank of America National Trust and
Savings Association, 555 California Street, 6th Floor, San Francisco, California
94104, Attention: Corporate Secretary, or hand delivered to the Secretary of the
Company at or before the taking of the vote at the Meeting.
 
     Management does not know of any matters to be presented at the Meeting
other than those set forth in this Proxy Statement and the accompanying Notice.
If other matters should properly come before the Meeting, the proxy holders will
vote on such matters in accordance with their best judgment, unless such
authority is withheld. Shares of Common Stock represented at the Meeting by a
properly executed, dated and returned proxy will be treated as present at the
Meeting for purposes of determining a quorum, without regard to whether the
proxy is marked as casting a vote or abstaining. Proxies relating to shares of
Common Stock held in "street name" by brokers will be counted as shares of
Common Stock present for purposes of determining the presence of a quorum, but
will not be treated as shares having voted at the Meeting as to approval and
adoption of the Merger Agreement if instructions as to how to vote thereon are
not given by the beneficial owners thereof to the broker. Abstentions will be
treated as shares of Common Stock that are present at the Special Meeting for
purposes of determining whether a quorum exists but will have the effect of
votes against approval and adoption of the Merger Agreement. In light of the
treatment of abstentions and broker non-votes and the fact that the affirmative
votes required to authorize and adopt the Merger Agreement are stated
percentages of the total number of outstanding shares of Common Stock on the
Record Date, abstentions and broker non-votes will have the same effect as votes
against the approval and adoption of the Merger Agreement. Because of
BankAmerica's current intention to vote its shares in favor of the approval and
adoption of the Merger Agreement, no action of any other stockholder will be
required to approve and adopt the Merger Agreement.

                                SPECIAL FACTORS
 
BACKGROUND OF THE MERGER
 
     The Company and its Initial Public Offering
 
     The Company was incorporated in October 1996. On December 3, 1996, the
merchant processing business of Bank of America, a multi-state operation based
in California, and the merchant processing business of the Seafirst Bank
Division of Bank of America NW, National Association ("Bank NW"), with assets
located principally in the State of Washington, were transferred to the Company.
At December 31, 1996, both Bank of America and Bank NW were wholly owned
subsidiaries of BankAmerica Corporation, a Delaware corporation (referred to
herein as "BAC" when the context refers to such corporation prior to its merger
with NationsBank Corporation, as described below under "-- Consideration of the
Merger"). On January 1, 1997, Bank NW was merged with and into Bank of America.
 
     On December 19, 1996, the Company commenced initial public offerings (the
"Offerings") of 16.1 million shares of the Class A Common Stock at $15.50 per
share. Of these shares, 12.9 million shares were offered in the United States
and 3.2 million shares were offered in a concurrent international offering
outside the United States. The Company completed the Offerings on December 31,
1996. Net proceeds from the Offerings were $232.9 million.
 
     During the second and third quarters of 1997, the Company acquired BAC's
merchant processing businesses in Thailand, the Philippines and Taiwan and its
merchant processing administrative office in Hong Kong in consideration for a
total of 2.2 million newly-issued shares of Class B Common Stock. The
acquisition of these entities is collectively referred to herein as the "Asia
Acquisitions."
 
     As a result of the completion of the Offerings and the subsequent Asia
Acquisitions, BankAmerica indirectly owns 100 percent of the outstanding Class B
Common Stock which, as of the date of this Proxy Statement, represented
approximately 66.6% of the economic ownership of the Company and 95.2% of the
combined voting power of the Company.
 
     For additional information, see "Certain Transactions and Relationships
Between BankAmerica and the Company."
 
     Consideration of the Merger
 
     On April 13, 1998, BAC and NationsBank Corporation ("NationsBank")
announced an agreement and plan of merger pursuant to which BAC and NationsBank
would merge into a combined bank holding company (the "BankAmerica/NationsBank
Merger").
 
     On May 29, 1998, following discussions with BAC and NationsBank, the
Company announced that BAC and NationsBank had determined that the Company would
be the principal merchant processor for their
 
                                       15
<PAGE>   20
 
combined organization following the BankAmerica/NationsBank Merger. Prior to
such time, NationsBank offered merchant processing services through Unified
Merchant Services ("UMS"), a joint venture that NationsBank formed in April 1995
with NaBANCO, the predecessor to First Data Corporation ("FDC"), a large
merchant payment services company. In connection with the formation of UMS,
NationsBank acquired a 20% ownership interest in UMS.
 
     On September 30, 1998, the BankAmerica/NationsBank Merger was consummated.
 
     The possible acquisition by BankAmerica of the entire economic interest in
the Company became the subject of internal study by BankAmerica in October 1998,
following the BankAmerica/NationsBank Merger. Senior management of BankAmerica
determined in mid-October 1998 to pursue the possibility of acquiring the entire
economic interest in the Company and determined to raise the matter with the
Board of Directors of the Company at its next regularly scheduled meeting on
October 22, 1998. For a discussion of BankAmerica's reasons for pursuing the
acquisition of the entire economic interest in the Company at this time, see
"Reasons for the Merger; Recommendation of the Company's Board of Directors and
the Special Committee -- BankAmerica."
 
     At the Company's October 22, 1998 regularly scheduled Board of Directors
meeting, a representative of BankAmerica's Corporate Strategy and Development
Department attended and proposed to the Company's Board of Directors a merger
transaction (the "Merger") in which each share of Class A Common Stock not owned
by BankAmerica would be converted into the right to receive $15.50 in cash. As a
result of the Merger, the Company would become a wholly owned subsidiary of Bank
of America.
 
     On October 22, 1998, the Company and BankAmerica each issued a press
release announcing the BankAmerica proposal.
 
     On November 13, 1998, BankAmerica announced that it planned to sell its 20%
ownership interest in UMS to FDC. This sale was completed on December 18, 1998.
 
     The Special Committee
 
     On October 22, 1998, at a regularly scheduled meeting of the Company's
Board of Directors, following receipt of the BankAmerica proposal, a Special
Committee was appointed to evaluate and consider the BankAmerica proposal. The
Special Committee consisted of Donald R. Dixon, William E. Fisher and Hatim A.
Tyabji, three of the Company's directors not otherwise affiliated with
BankAmerica. Mr. Tyabji was originally appointed as Chairman of the Special
Committee.
 
     Mr. Dixon has served as a member of the Board of Directors of the Company
since November 1996. He has been the president of Trident Capital, Inc., a
venture capital firm, since 1993. He was co-president of Partech International,
a private equity fund manager associated with Banque Paribas, from 1988 to 1993.
Prior to that time, he was a managing director of Alex Brown & Sons,
Incorporated and a vice president of Morgan Stanley & Co. Mr. Fisher has served
as a member of the Board of Directors of the Company since November 1996. He is
the president, chief executive officer and chairman of Transaction Systems
Architects, Inc., where he has been employed since 1987. Mr. Tyabji has served
as a member of the Board of Directors of the Company since May 1998. He was the
president and chief executive officer of VeriFone Inc. commencing in 1986 and
was the chairman of VeriFone Inc. commencing in 1992 until retiring from such
positions in 1998.
 
     The initial mandate of the Special Committee was to review, evaluate and
make recommendations to the Company's Board of Directors regarding the
BankAmerica proposal. The Company's Board of Directors also authorized the
Special Committee to select and retain, at the Company's expense, independent
legal, financial and other advisors to advise and assist the Special Committee
in connection with the BankAmerica proposal.
 
     On October 22, 1998, following the meeting of the Company's full Board of
Directors, the Special Committee held a meeting at which representatives of
Cooley Godward LLP, Palo Alto, California, and representatives of Credit Suisse
First Boston Corporation ("CSFB") were present, to discuss the possible
retention of Cooley Godward as independent legal counsel to the Special
Committee and the possible engagement of CSFB as independent financial advisor
to the Special Committee.
 
                                       16
<PAGE>   21
 
     On October 23, 1998, the Special Committee held a meeting at which
representatives of Cooley Godward and CSFB were present to further discuss the
retention of Cooley Godward as independent legal counsel to the Special
Committee and the engagement of CSFB as independent financial advisor to the
Special Committee. At such meeting, the Special Committee also discussed with
Cooley Godward the mandate of the Special Committee and determined that it would
be advisable for the Special Committee to consider, with the assistance of
Cooley Godward and Delaware counsel, whether the Special Committee's mandate, as
established by the Company's Board of Directors, should be expanded. The Special
Committee asked Cooley Godward to help the Special Committee identify possible
Delaware counsel to the Special Committee. In addition, although the Special
Committee was not prepared to formally engage CSFB until it was satisfied that
such firm was sufficiently independent from BankAmerica, at such meeting the
Special Committee asked CSFB to commence a due diligence review of the Company.
Following the October 23, 1998 Special Committee meeting, CSFB commenced its
financial due diligence which included a series of meetings with Company
management.
 
     On October 29, 1998, the Special Committee met with representatives of
Cooley Godward and CSFB and formally determined to retain Cooley Godward as
independent legal counsel to the Special Committee. The Special Committee also
further reviewed the engagement of CSFB as independent financial advisor to the
Special Committee.
 
     On November 5, 1998, the Special Committee met with representatives of
Cooley Godward, CSFB and Richards, Layton & Finger, P.A., Wilmington, Delaware.
At such meeting the Special Committee formally determined to engage CSFB as the
independent financial advisor to the Special Committee and discussed the
retention of Richards, Layton & Finger as independent Delaware counsel to the
Special Committee. The Special Committee subsequently formally engaged Richards,
Layton & Finger as special Delaware counsel.
 
     The engagement of CSFB, as well as the retention of legal counsel, was
determined following the Special Committee's conclusion that neither CSFB nor
legal counsel had previously been engaged in any respect by the Company, BAC,
BankAmerica or NationsBank, or their respective affiliates, which would
materially and adversely affect their ability to represent and advise the
Special Committee. In so concluding, the Special Committee gave careful
consideration to certain previous engagements of CSFB by BankAmerica and
NationsBank and also considered certain legal engagements by BAC, BankAmerica
and certain of their affiliates of the legal counsel to the Special Committee.
The previous engagements of CSFB by BankAmerica or NationsBank included an
engagement to advise NationsBank in a previous acquisition of a securities firm
in 1997 and an engagement by BankAmerica in 1998 to advise it in connection with
an asset portfolio sale, which transaction had been deferred indefinitely. The
previous engagements of Cooley Godward by BankAmerica and various affiliates of
BAC and BankAmerica involved limited representations, for which such counsel had
received legal fees in an amount not material to such firm. Both CSFB and such
legal counsel gave assurances to the Special Committee to the effect that those
prior engagements would not materially and adversely affect their ability to
represent and advise the Special Committee.
 
     At the October 29, 1998 Special Committee meeting, the Special Committee
also requested and received a report from Cooley Godward regarding the
Stockholders' Litigation (as defined below) and requested that updates regarding
the Stockholders' Litigation be provided at future Special Committee meetings.
Such updates were provided from time to time at subsequent Special Committee
meetings. The Special Committee also requested and received a report from CSFB
regarding its financial due diligence to that date and the likely timing of the
completion by CSFB of its financial analyses. It was also reported at such
meeting that Mr. Tyabji had been admitted to the hospital for personal health
reasons and would not be able to participate in Special Committee matters for an
undetermined period of time.
 
     At the November 5, 1998 Special Committee meeting, representatives of CSFB
discussed with the Special Committee the status of CSFB's due diligence
investigation of the Company and certain preliminary financial analyses
performed by CSFB regarding the Company and the BankAmerica proposal. See
"-- Opinion of CSFB." CSFB also advised the Special Committee that, based upon
its preliminary valuation analyses, if asked, it might not be able to render an
opinion to the Special Committee to the effect that a price of $15.50 per share
of Class A Common Stock is fair to the public stockholders of the Company from a
 
                                       17
<PAGE>   22
 
financial point of view. It was also decided at such meeting that, in light of
Mr. Tyabji's health problems, the Special Committee would recommend to the
Company that Mr. Tyabji be removed from the Special Committee. Moreover, it was
decided that Mr. Dixon would be the Chairman of the Special Committee and that
the Special Committee would defer making any decision relating to the
BankAmerica proposal until the mandate of the Special Committee was
appropriately expanded.
 
     On November 10, 1998, at a meeting of the Board of Directors of the
Company, the mandate of the Special Committee was expanded. The expanded mandate
authorized the Special Committee to review, consider and evaluate, and take all
actions that the Special Committee deemed appropriate to determine the
advisability of, the BankAmerica proposal, including such actions as negotiating
with BankAmerica the terms of the transaction contemplated by the BankAmerica
proposal, to cause the Company to take such actions as the Special Committee
deemed appropriate in connection with the BankAmerica proposal and to make
recommendations to the Board of Directors regarding the BankAmerica proposal.
The Company's Board of Directors also removed Mr. Tyabji from the Special
Committee due solely to personal health problems.
 
     On November 12, 1998, the Special Committee met with representatives of
Cooley Godward, Richards, Layton & Finger and CSFB. At such meeting, the Special
Committee reviewed further with CSFB its analyses of the BankAmerica proposal
and directed a representative of CSFB to contact a representative of BankAmerica
and advise him that the Special Committee had concluded that the $15.50 proposal
was inadequate, but that the Special Committee remained willing to discuss a
transaction at an appropriate price. After the adjournment of the November 12,
1998 meeting, a representative of CSFB contacted a representative of BankAmerica
and advised him that the $15.50 proposal was inadequate, but that the Special
Committee remained willing to discuss a transaction at an appropriate price.
 
     On November 16, 1998, the Company issued a press release identifying the
legal counsel and the financial advisor selected by the Special Committee and
announcing that the Special Committee had determined that the $15.50 per share
value offered by BankAmerica was inadequate, but that the Special Committee
remained willing to discuss a transaction at an appropriate per share value.
 
     At a meeting of the Company's Board of Directors held on December 1, 1998,
in light of a significant improvement in Mr. Tyabji's health, Mr. Tyabji was
reinstated to the Special Committee.
 
     On December 5, 1998, the Special Committee met with representatives of
Cooley Godward, Richards, Layton & Finger and CSFB. In addition to the other
members of the Special Committee, Mr. Tyabji, whose health had significantly
improved and who had been reinstated to the Special Committee, was present at
such meeting. The members of the Special Committee and the Special Committee's
advisors discussed the BankAmerica proposal and the request made by BankAmerica
for a meeting between the members of the Special Committee and representatives
of BankAmerica. The members of the Special Committee and the Special Committee's
advisors also discussed the request made by one of the Company's major public
stockholders for a meeting with the Special Committee. Following such
discussion, it was determined that the members of the Special Committee and
representatives of CSFB would meet with BankAmerica and that the members of the
Special Committee, together with representatives of CSFB and a representative of
Cooley Godward, would make themselves available to listen to the major
stockholder's views regarding the BankAmerica proposal.
 
     On December 7, 1998, the members of the Special Committee, together with
representatives of CSFB and a representative of Cooley Godward, made themselves
available to listen to the views of a major stockholder of the Company regarding
the BankAmerica proposal. In addition, on December 7, 1998, representatives of
BankAmerica met with the members of the Special Committee and representatives of
CSFB to further discuss the BankAmerica proposal. At the beginning of the
meeting, the members of the Special Committee and the representatives of CSFB
stated the position that the $15.50 proposal was inadequate.
 
     The representatives of BankAmerica responded that there were a number of
factors supporting the adequacy and fairness of the proposed consideration. The
BankAmerica representatives noted that, in their
 
                                       18
<PAGE>   23
 
opinion, the market value of the Company's stock at the time BankAmerica
originally submitted its proposal to the Company's Board of Directors fairly
valued the Company and the BankAmerica proposal represented a reasonable premium
over that value. The BankAmerica representatives also noted that, in their
opinion, the attractiveness of the merchant services industry was highly
uncertain at this time. It was further noted that, in their opinion, there has
been considerable competitive price compression on the fees for merchant
services. Changes in interchange fees charged to merchants by the credit card
issuers have also been occurring and are expected to continue causing the risk
of customer attrition to increase. It was also noted that analysts differ on
industry growth rates with expectations ranging from a relatively modest six to
eight percent to approximately 13% and that this has contributed to the relative
underperformance of merchant services stocks in the past several years. The
representatives of BankAmerica also noted that, in their opinion, the strategic
position of the Company was uncertain and in some cases had become disadvantaged
in terms of its stock value relative to its major competitors. In that regard,
it was noted that certain independent merchant processors have been able to
successfully complete acquisitions using pooling of interests accounting which
is not available to the Company due to its affiliation with BankAmerica. It was
also noted that the original promise of the Company's business in Asia has
dimmed in light of the financial and economic difficulties of that region. The
representatives of BankAmerica also noted that the trading price of the
Company's stock had compared unfavorably to its major competitors. It was also
indicated that, while the BankAmerica/NationsBank Merger presents some
opportunities for the Company, it is not clear that the Company's success rate
in Bank of America's existing branch network in acquiring new merchant customers
through referrals will be transferable in the near term to the subsidiaries of
NationsBank given the lack of a common history and culture. It was also noted
that the fee arrangement for referrals from subsidiaries of NationsBank had yet
to be determined, as had the timing of the merger of the NationsBank banking
affiliates and Bank of America. BankAmerica also noted that there was a limited
term (approximately three years) remaining on its current contractual
arrangements with the Company.
 
     The representatives of BankAmerica then indicated, however, their
willingness to increase the offered price in light of movement in market
conditions for the merchant processing sector since the announcement of the
BankAmerica proposal in late October. They indicated a cash price of $19.30 per
share would be acceptable. The representatives of CSFB indicated that they
believed that the Special Committee would consider a proposal at a cash per
share price of $21.75. BankAmerica's representatives responded to the
representatives of CSFB that in light of the Special Committee's insistence on a
higher value, BankAmerica would be willing to entertain a cash price of $19.90
per share. The representatives of CSFB strongly suggested that the $19.90 per
share price would not be deemed adequate by the Special Committee. After further
discussions, the representatives of BankAmerica indicated a tentative
willingness to agree upon a cash price of $20.50 per share, subject to agreement
on other significant terms of the transaction, and subject to approval by the
Board of Directors of BankAmerica and the negotiation of a satisfactory
definitive agreement. After further discussion and deliberation, the members of
the Special Committee determined it could consider a BankAmerica proposal of
$20.50 per share, subject to the negotiation of a satisfactory merger agreement
which, among other terms, would not contain significant conditions to closing
and the receipt of a fairness opinion from CSFB.
 
     At the meeting on December 7, 1998, the representatives of BankAmerica also
expressed their desire that a resolution of the pending stockholder litigation
be a condition to completing the Merger. See "The Merger -- Litigation." The
representatives of CSFB expressed to the representatives of BankAmerica their
belief that the merger agreement to be negotiated should not be subject to
extensive conditions. The parties to the negotiation agreed that counsel to
BankAmerica should promptly contact legal counsel to the plaintiffs in the
pending stockholder litigation to determine whether a settlement to such
litigation might be possible in light of all the circumstances. Such contact was
made initially on December 11, 1998, and telephone contacts continued on a
number of occasions from December 11, 1998 to December 18, 1998, at which time
an agreement in principle was reached with plaintiffs' counsel for a settlement
of such litigation. On December 22, 1998, a Memorandum of Understanding (the
"MOU") was executed by counsel for the plaintiffs, BankAmerica, the Company and
the other defendants in such litigation relating to the settlement of such
litigation, subject to certain conditions. See "The Merger -- Litigation."

     After the conclusion of the December 7, 1998 meeting, BankAmerica
instructed its counsel to prepare a draft of a definitive merger agreement which
was first submitted to counsel to the Special Committee for review on December
11, 1998.
 
     On December 11, 1998, the Special Committee met with representatives of
Cooley Godward, Richards, Layton & Finger and CSFB. At such meeting the Special
Committee reviewed with CSFB the revised BankAmerica proposal of $20.50 per
share and discussed with representatives of Cooley Godward the draft merger
agreement.
 
     On December 13, 1998, legal counsel to BankAmerica and legal counsel to the
Special Committee held a telephone conference call to discuss BankAmerica's
proposed merger agreement.
 
     On December 15, 1998, the Board of Directors of BankAmerica approved the
Merger at a meeting held in Charlotte, North Carolina, and authorized the
appropriate officers of BankAmerica to negotiate, execute and deliver a merger
agreement relating to the Merger.
 
     On December 15, 16 and 18, 1998, the Special Committee, its legal counsel
and CSFB held meetings to consider the proposed merger agreement.
 
     On several occasions between December 15 and 21, 1998, legal counsel for
BankAmerica and legal counsel for the Special Committee conferred by telephone
about the terms and provisions of the proposed merger agreement and exchanged
several further drafts of the merger agreement as the negotiations continued.
 
     On December 21, 1998, the Special Committee met again with CSFB and legal
counsel. At such meeting, the Special Committee reviewed with CSFB and legal
counsel the draft merger agreement and the BankAmerica proposal. CSFB rendered
its oral opinion, subsequently confirmed in writing on December 21, 1998, that,
as of such date, the consideration of $20.50 per share of Class A Common Stock
to be received by the holders (other than BankAmerica and its affiliates) of the
Class A Common Stock in the Merger is fair to such holders from a financial
point of view. At such time the members of the Special Committee unanimously
determined that the terms of the Merger Agreement and the Merger, including the
price per share of $20.50 for the Class A Common Stock, were in the best
interests of the holders of the shares of Class A Common Stock and unanimously
agreed to recommend to the Board of Directors of the Company that it approve the
terms of the Merger Agreement and the Merger. See "-- Opinion of CSFB."
 
     Later in the day on December 21, 1998, the Board of Directors of the
Company, including the members of the Special Committee, met to consider the
Merger Agreement. The members of the Special Committee informed the Board of
Directors of the Company that it recommended approval of the Merger Agreement
and the Merger. The Board of Directors of the Company, by unanimous vote of all
directors, approved the proposal and authorized the execution and delivery of
the Merger Agreement.
 
     Thereafter, legal counsel to BankAmerica and legal counsel to the Special
Committee finalized the Merger Agreement, and the Merger Agreement was executed
and delivered by officers of BankAmerica, Acquisition Corp. and the Company with
the terms approved by the Boards of Directors of the Company and Acquisition
Corp.
 
     On December 22, 1998, prior to commencement of trading on the NYSE,
BankAmerica and the Company jointly announced the execution of the Merger
Agreement and the agreement in principle regarding the settlement of the
Stockholders' Litigation. See "The Merger -- Litigation."
 
     In addition to the foregoing meetings, the members of the Special
Committee, both individually and together, conferred frequently with their legal
counsel and CSFB or both, and with each other concerning aspects of the
BankAmerica proposal and the issues that arose in connection with the proposal
and the negotiation of a final transaction.

REASONS FOR THE MERGER; RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS AND
THE SPECIAL COMMITTEE
 
     BankAmerica
 
     BankAmerica determined to make the proposal to acquire ownership of all of
the outstanding common stock of the Company for several reasons. First, the
BankAmerica/NationsBank Merger, coupled with changes in the merchant processing
industry, altered many of the original motivations for the Offerings of the
Company's stock in 1996. Among other things, BankAmerica's management perceived
that conflicts were arising between BankAmerica's evolving retail and commercial
bank strategy of customer orientation and integrated product delivery and the
orientation of the Company as an independent "monoline" company. Additionally,
the market value of the Company's stock, and that of stocks in the merchant
processing industry generally, since 1996 have compared unfavorably to the
market values prevailing in the financial services industry generally, including
values of the stocks of major bank holding companies such as BankAmerica, and
the sector multiples between these segments of the financial services industry
have converged in recent years. Management of BankAmerica had also begun to
reconsider the original strategy of using acquisitions to grow the business of
the Company.
 
     The Company
 
     The Board of Directors of the Company, in accordance with the unanimous
recommendation of the Special Committee, recommends that the Company's
stockholders vote FOR approval and adoption of the Merger Agreement. The Board
of Directors, including the members of the Special Committee, and BankAmerica
believe that the Merger is fair to and in the best interests of holders of Class
A Common Stock (other than BankAmerica and its affiliates) for the reasons
described below in "-- The Special Committee."
 
     The Special Committee
 
     The Special Committee believes that the Merger is fair to and in the best
interests of holders of Class A Common Stock (other than BankAmerica and its
affiliates) and unanimously recommends that such holders vote FOR approval and
adoption of the Merger Agreement.
 
     In determining that the Merger is fair to holders of Class A Common Stock
and recommending the approval of the Merger Agreement, the Special Committee
considered the following factors among others:
 
     Stock Ownership and Voting Power of BankAmerica.  The Special Committee
recognized that BankAmerica owns approximately 66.6% of the outstanding economic
interest in the Company and 95.2% of the voting power of the Company. This
ownership precluded any acquisition by a third party without BankAmerica's
consent, and BankAmerica advised the Special Committee that it would not be
willing to consider the possibility of selling its interest in the Company now
or in the future.
 
     The Special Committee also recognized that BankAmerica had sufficient
voting power to eliminate the minority interest in the Company in a transaction
not approved by the Special Committee or the Company's Board of Directors.
 
     Fairness Opinion and Related Presentations.  The Special Committee
considered the opinion delivered orally to it by CSFB to the effect that as of
the date of such opinion the consideration to be received by the Company's
stockholders (other than BankAmerica and its affiliates) in the Merger was fair
to such stockholders from a financial point of view.
 
     The Special Committee also considered the advice it received from CSFB
during the course of its engagement, including the CSFB Opinion (as defined
below) and the analyses relating to such opinion described below under
"-- Opinion of CSFB." The Special Committee considered the international
reputation of CSFB, its extensive experience in mergers and acquisition
transactions and the fact that the fees payable to CSFB were not conditioned
upon the conclusion reached with respect to fairness of the Merger.
 
     The Special Committee also considered as favorable the fact that the $20.50
per share represented a significant premium over the $13.625 per share closing
price on the day prior to the announcement of the BankAmerica proposal.
 
                                       21
<PAGE>   26
 
     Arm's-Length Negotiations.  The Special Committee considered as favorable
that the terms of the Merger were reached through arm's-length negotiations by
the Special Committee and its independent legal and financial advisors with
BankAmerica and its legal advisors. The Special Committee does not believe that
further negotiations would have resulted in a superior merger proposal.
 
     Terms of the Merger Agreement.  The Special Committee considered the terms
of the Merger Agreement generally to be favorable. In particular, the Special
Committee viewed as favorable, among other things, the fact that the Merger
Agreement (a) contains only a limited number of representations and warranties,
(b) requires BankAmerica to vote in favor of the Merger unless the Special
Committee revokes, modifies or qualifies its recommendation with respect to the
Merger, (c) does not require the payment of a termination fee if the Merger
Agreement is terminated, and (d) imposes no significant conditions to the
closing of the Merger, thus making consummation of the Merger more likely than
one that imposes more significant conditions to consummation.
 
     Appraisal Rights.  The Special Committee considered as favorable the fact
that holders of shares of Class A Common Stock (other than BankAmerica) would be
entitled under the DGCL to obtain a judicial determination of the fair value of
their shares. See "The Merger -- Appraisal Rights."
 
     The foregoing discussion of factors considered by the Special Committee is
not intended to be exhaustive but is believed to include all material factors
considered by the Special Committee. Given the variety and complexity of the
factors considered by the Special Committee in its evaluation of the terms of
the Merger, it did not find it practicable to, and did not, quantify or
otherwise attempt to assign relative weights to the specific factors it
considered in reaching its determinations.
 
OPINION OF CSFB
 
     CSFB is acting as the exclusive financial advisor to the Special Committee
in connection with the Merger. CSFB was selected by the Special Committee to act
as its financial advisor based on CSFB's qualifications, expertise and
reputation, as well as CSFB's familiarity with the Company.
 
     On December 21, 1998, the Special Committee met to review the Merger and
the final terms of the Merger Agreement. During this meeting, CSFB rendered its
oral opinion, subsequently confirmed in writing on December 21, 1998 (the "CSFB
Opinion"), that, as of that date, based upon and subject to the various
considerations set forth in the CSFB Opinion, the Merger Consideration to be
received by the holders of Class A Common Stock, other than BankAmerica and its
affiliates, in the Merger is fair to such stockholders from a financial point of
view.
 
     THE FULL TEXT OF THE CSFB OPINION, WHICH SETS FORTH, AMONG OTHER THINGS,
THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED, AND
QUALIFICATIONS AND LIMITATIONS ON THE SCOPE OF THE REVIEW UNDERTAKEN BY CSFB IN
RENDERING THE CSFB OPINION, IS ATTACHED AS ANNEX II TO THIS DOCUMENT AND
INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS ARE URGED TO, AND SHOULD, READ
THE CSFB OPINION CAREFULLY AND IN ITS ENTIRETY. THE CSFB OPINION WAS DELIVERED
TO THE SPECIAL COMMITTEE FOR ITS USE IN CONNECTION WITH ITS CONSIDERATION OF THE
MERGER AND ADDRESSES ONLY THE FAIRNESS OF THE MERGER CONSIDERATION TO BE
RECEIVED BY THE HOLDERS OF CLASS A COMMON STOCK, OTHER THAN BANKAMERICA AND ITS
AFFILIATES, FROM A FINANCIAL POINT OF VIEW AS OF THE DATE OF THE CSFB OPINION.
THE CSFB OPINION IS NOT INTENDED TO BE, AND DOES NOT CONSTITUTE, A
RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE
MEETING. THE SUMMARY OF THE CSFB OPINION SET FORTH IN THIS DOCUMENT IS QUALIFIED
IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE CSFB OPINION.

     A copy of the CSFB financial analysis discussed below has been filed as an
exhibit to the Rule 13e-3 Transaction Statement on Schedule 13E-3 (the "Schedule
13E-3") filed with the Commission with respect to the Merger, and will be made
available for inspection and copying at the Company's principal executive
offices at One South Van Ness Avenue, San Francisco, California 94103 during
regular business hours by any interested stockholder or his or her
representative who has been so designated in writing.
 
     In arriving at its opinion, CSFB reviewed certain publicly available
business and financial information relating to the Company, including, but not
limited to, the terms and conditions of the existing contractual relationship
between the Company and BankAmerica, as well as the Merger Agreement. CSFB also
reviewed certain other information, including financial forecasts, provided to
it by the Company and met with the Company's management to discuss the business
and prospects of the Company. See "-- Certain Projected Financial Information."
 
     CSFB also considered certain financial and stock market data of the
Company, and compared that data with similar data for other publicly-held
companies in businesses similar to those of the Company. CSFB also considered
the financial terms, to the extent publicly available, of certain other business
combinations and other transactions which had recently been effected. CSFB
considered that BankAmerica's ownership of 100% of the outstanding shares of
Class B Common Stock represents 95.2% of the voting power of the outstanding
Common Stock. CSFB also considered such other information, financial studies,
analyses and investigations and financial, economic and market criteria which it
deemed relevant.
 
     In connection with its review, CSFB did not assume any responsibility for
independent verification of any of the foregoing information and relied on its
being complete and accurate in all material respects. With respect to the
financial forecasts, CSFB assumed, with the permission of the Special Committee,
that they had been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the Company's management as to the future
financial performance of the Company. In addition, CSFB did not make an
independent evaluation or appraisal of the assets or liabilities (contingent or
otherwise) of the Company, nor was CSFB furnished with any such evaluations or
appraisals. The CSFB Opinion was necessarily based upon financial, economic,
market and other conditions as they existed and could be evaluated as of the
date of the CSFB Opinion. CSFB was not requested to, and at the Special
Committee's direction did not, solicit third party indications of interest in
acquiring all or any part of the Company.
 
     In preparing the CSFB Opinion, CSFB performed a variety of financial and
comparative analyses. The preparation of a fairness opinion is a complex process
and is not necessarily susceptible to partial analysis or summary description.
CSFB believes that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all analyses and factors, could create a misleading view of the
processes underlying the CSFB Opinion. No company or transaction used in the
analysis performed by CSFB as a comparison is identical to the Company or the
contemplated transaction. In addition, CSFB may have given various analyses more
or less weight than other analyses, and may have deemed various assumptions more
or less probable than other assumptions, so that the range of valuation
resulting from any particular analysis described below should not be taken to be
CSFB's view of the actual value of the Company. In performing its analyses, CSFB
made numerous assumptions with respect to industry performance, general business
and economic conditions and other matters, many of which are beyond the control
of the Company. The analyses performed by CSFB are not necessarily indicative of
actual values or actual future results, which may be significantly more or less
favorable than suggested by such analyses. In addition, analyses relating to the
value of businesses or assets do not purport to be appraisals or to necessarily
reflect the prices at which businesses or assets may actually be sold. The
analyses performed were prepared solely as part of CSFB's analysis of the
fairness of the consideration to be received by the Company's stockholders,
other than BankAmerica or its affiliates, from a financial point of view and
were provided to the Special Committee in connection with the delivery of the
CSFB Opinion.
 
     The following is a summary of the material analyses performed by CSFB in
connection with the preparation of the CSFB Opinion, and reviewed with the
Special Committee at a series of meetings culminating in a meeting held on
December 21, 1998.
 
                                       23

     Historical Stock Price Analysis.  CSFB analyzed the prices at which Class A
Common Stock traded over the 498 trading days subsequent to the Company's
initial public offering on December 19, 1996 through December 9, 1998 (the
"Observed Period"). CSFB noted that the all-time high price for Class A Common
Stock was $21.81 on September 22, 1997 and the all-time low price for Class A
Common Stock was $10.38 on October 9, 1998. CSFB noted that 32.1% of shares of
Class A Common Shares traded during the Observed Period were traded for a price
below $16.00 per share, 62.1% were traded for a price between $16.00 to $20.00,
and 5.8% were traded for a price above $20.00 per share.
 
     Comparative Stock Price Performance.  As part of its analyses, CSFB
reviewed the recent stock price performance of the Company and compared such
performance with that of other companies involved in the transaction processing
industry including Concord EFS, Inc.; First Data Corporation; National Data
Corporation; National Processing, Inc.; NOVA Corporation; Paymentech, Inc.;
Total System Services, Inc.; and Transaction Network Services, Inc.
(collectively, the "Transaction Processors"). CSFB noted that during the
Observed Period, the market price of Class A Common Stock decreased 3.6%,
compared with a decrease of 12.2% for the Transaction Processors and an increase
of 58.2% for the NASDAQ composite index. CSFB noted that over the Observed
Period, Class A Common Stock underperformed relative to the NASDAQ composite
index and outperformed the Transaction Processors.
 
     Peer Group Comparison.  CSFB compared certain information relating to the
Company with the Transaction Processors. Such information included, among other
things, share price as a multiple of next twelve months ("NTM") earnings per
share ("EPS") and share price as a multiple of NTM EPS divided by the First Call
consensus estimated long-term growth rate. The multiples are based on a
compilation of publicly available information and consensus forecasts by
securities research analysts.
 
     CSFB noted that, during the Observed Period, Class A Common Stock traded at
an average multiple of 19.2 times NTM EPS, while the Transaction Processors
traded at an average multiple of 29.7 times NTM EPS. CSFB also noted that
Paymentech, Inc. ("PTI") and National Processing, Inc. ("NAP"), two companies
involved in the transaction processing industry which are majority owned by
another company, traded at an average multiple of 25.2 times and 15.6 times NTM
EPS, respectively, over the Observed Period. CSFB noted that, during the
Observed Period, the average multiple of NTM EPS at which Class A Common Stock
traded represented a discount of 35.4%, a discount of 22.9% and a premium of
25.0% to the average multiple of NTM EPS at which the Transaction Processors,
PTI, and NAP, respectively, traded.
 
     CSFB noted that, during the Observed Period, Class A Common Stock traded at
an average multiple of 1.01 times NTM EPS divided by the First Call consensus
estimated long-term growth rate, while the Transaction Processors traded at an
average multiple of 1.37 times NTM EPS divided by the First Call consensus
estimated long-term growth rate. CSFB also noted that PTI and NAP traded at
average multiples of 1.14 times and 0.99 times NTM EPS divided by the First Call
consensus estimated long-term growth rate, respectively.
 
     Selected Precedent Transactions.  CSFB reviewed the publicly available
financial terms of six precedent transactions in technology-based services (the
"Technology-Based Services Transactions"):
 
     - Concord EFS, Inc./Electronic Payment Services, Inc.
     - DST Systems, Inc./USCS International, Inc.
     - NOVA Corporation/PMT Services, Inc.
     - Associates First Capital Corporation/SPS Transaction Services, Inc.
     - First Data Corporation/First Financial Management Corporation
     - First Data Corporation/Card Establishment Services
 
     For the Technology-Based Services Transactions, CSFB observed a range of
multiples of aggregate value to latest twelve months ("LTM") revenue of 2.00 to
4.00 times, aggregate value to LTM earnings before interest, taxes, depreciation
and amortization ("EBITDA") of 10.0 to 18.0 times, aggregate value to LTM
earnings before interest and taxes ("EBIT") of 12.0 to 24.0 times, share price
to LTM EPS of 20.0 to 36.0 times and share price to First Call next fiscal year
EPS of 20.0 to 32.0 times. The multiples of aggregate value to LTM revenue,
aggregate value to LTM EBITDA, aggregate value to LTM EBIT, share price to LTM
EPS
 
                                       24
<PAGE>   29
 
and share price to First Call next fiscal year EPS implied a value per share of
Class A Common Stock of $9.22 to $16.00, $16.50 to $28.55, $15.84 to $29.93,
$16.25 to $29.26, and $20.80 to $33.28, respectively.
 
     Premium Analysis.  CSFB reviewed publicly available premiums paid in 102
selected precedent minority-squeeze out transactions between January 1, 1990 and
December 11, 1998 (the "Precedent Minority Squeeze-Outs"); the Technology-Based
Services Transactions; and 4,686 mergers and acquisitions between January 1,
1990 and November 1, 1998 (the "M&A Transactions"). Such analysis compared the
average premiums paid in each transaction over the stock price one day, one
week, and one month preceding the public announcement of each transaction. CSFB
applied these premia to the $13.63 closing price per share of Class A Common
Stock on October 22, 1998 (the last trading day prior to BankAmerica's initial
offer to purchase all shares of Class A Common Stock outstanding for $15.50 per
share or the "Unaffected Date"), and to the theoretical price per share of Class
A Common Stock of $14.80 (the "Indexed Price") on December 9, 1998 implied by
the indexed return of the Transaction Processors from the Unaffected Date
through December 9, 1998. CSFB noted that the average premia in the Precedent
Minority Squeeze-Outs ranged from 19.7% to 26.1%, implying a value per share of
Class A Common Stock of $16.29 to $18.20. CSFB observed that the average premia
in the Technology-Based Services Transactions ranged from 20.2% to 33.2%,
implying a value per share of Class A Common Stock of $16.38 to $19.23. CSFB
noted that the average premia in the M&A Transactions ranged from 29.7% to
38.3%, implying a value per share of Class A Common Stock of $17.54 to $19.96.
 
     CSFB also reviewed the increase from the initial offer price to the final
offer price in 26 selected precedent minority squeeze-out transactions between
January 1, 1997 and December 10, 1998 (the "Recent Minority Squeeze-Outs"). CSFB
noted that there was no increase from the initial offer price to the final offer
price in 42.3% of the Recent Minority Squeeze-Outs, a 0% to 20% increase from
the initial offer price to the final offer price in 50.0% of the Recent Minority
Squeeze-Outs and a greater than 20% increase from the initial offer price to the
final offer price in 7.7% of the Recent Minority Squeeze-Outs. CSFB noted that
the increase from BankAmerica's initial offer price of $15.50 per share of Class
A Common Stock outstanding to BankAmerica's final offer price of $20.50 per
share of Class A Common Stock outstanding represented an increase of 32.3%.
 
     Discounted Cash Flow Analysis.  CSFB analyzed the present value of future
cash flows potentially realizable from the continued operation of the Company
based on estimates and guidance provided by the Company's management for
estimated Company operating results through the end of fiscal year 2004. CSFB
computed the present value of the free cash flows of the Company for the five
fiscal years from 1999 through 2003 by applying a range of discount rates of
12.0% to 15.0% per year. CSFB also computed the present value of the terminal
value of the Company at the end of fiscal year 2003 by applying a range of net
income multiples of 12.0 to 16.0 times the Company's estimated fiscal year 2004
net income and applying to these terminal values a range of discount rates of
12.0% to 15.0% per year. The range of terminal net income multiples was
determined by analyzing the current and historic NTM net income multiples of the
Company and the Transaction Processors and factoring in the expected growth
prospects of the Company at the end of fiscal 2003. The discounted cash flow
analysis implied a range of values per share of Class A Common Stock on a fully
diluted basis of $19.21 to $27.06.
 
     Potential Future Trading Value Analysis.  CSFB computed the present value
per share of Class A Common Stock under several future trading periods and
multiples. Such analysis was based upon the Company's expected EPS in fiscal
years 2000 and 2001 utilizing both First Call consensus EPS projections and the
Company's management EPS estimates. For a discussion of the Company management
estimates, see "-- Certain Projected Financial Information." CSFB calculated
implied future values per share of Class A Common Stock using multiples ranging
from 12.0 to 18.0 times the Company's NTM EPS for both fiscal 2000 and 2001. The
implied future values per share of Class A Common Stock were discounted to
arrive at a present value using discount rates of 12.0% and 15.0% per year. The
potential future trading value analysis implied a range of values per share of
Class A Common Stock of $12.91 to $23.24.
 
     As described above, CSFB's opinion and presentation to the Special
Committee was one of many factors taken into consideration by the Special
Committee in making its determination to recommend the Merger
 
                                       25
<PAGE>   30
 
Agreement and the transactions contemplated thereby. Consequently, the analyses
described above should not be viewed as determinative of the opinion of the
Special Committee, the Board of Directors, or the Company's management with
respect to the value of the Company or whether the Special Committee would have
been willing to recommend a Merger at a different level of consideration.
 
     The Special Committee retained CSFB to act as its financial advisor in
connection with the Merger. CSFB was selected by the Special Committee based on
CSFB's qualifications, expertise and reputation, as well as CSFB's familiarity
with the Company. CSFB is an internationally recognized investment banking and
advisory firm. CSFB, as part of its investment banking business, is continuously
engaged in the valuation of businesses and securities in connection with mergers
and acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. In the ordinary course of its
business, CSFB may actively trade the securities and loans of the Company and
BankAmerica and its affiliates for its own account and for the accounts of its
customers and, accordingly, may at any time hold a long or short position in
such securities and loans.
 
     Pursuant to a letter dated October 23, 1998 (the "Engagement Letter"), the
Company, at the direction of the Special Committee, engaged CSFB to provide
financial advisory services to the Special Committee in connection with the
Merger, including, among other things, rendering the CSFB Opinion and making the
presentation referred to above. Pursuant to the terms of the Engagement Letter,
the Company agreed to pay CSFB (i) a retainer fee of $150,000 and (ii) an
opinion fee of 0.80% of the product of the highest price per share of Class A
Common Stock offered by BankAmerica times the number of shares of Class A Common
Stock outstanding, against which the amount referred to in clause (i) would be
credited if previously paid. In addition, the Company has agreed to reimburse
CSFB for its out-of-pocket expenses, including attorney's fees, incurred in
connection with its engagement, and to indemnify CSFB and certain related
persons against certain liabilities and expenses arising out of or in
conjunction with its rendering of services under its engagement, including
liabilities arising under the federal securities laws.
 
CERTAIN PROJECTED FINANCIAL INFORMATION
 
     The Company does not, as a matter of course, make public forecasts or
projections as to future revenues or results of operations. However, in order to
aid the analysis of the proposed Merger by the Special Committee and CSFB and
CSFB's assessment of the fairness, from a financial point of view, of the Merger
Consideration, the Company furnished to the Special Committee and
representatives of CSFB certain estimates of the Company's future financial
performance. See "-- Opinion of CSFB." Management prepared such projections in
October 1998 and provided such projections to representatives of CSFB in early
November 1998. The projections furnished by management of the Company to CSFB
are attached to this Proxy Statement as Exhibit A.
 
     These projections constitute "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. Such
forward-looking statements are subject to risks and uncertainties and may be
affected by various factors that may cause actual results to differ materially
from those in the forward-looking statements. Actual results may differ from
management's expectations and beliefs based on a number of risks and
uncertainties, many of which risks and uncertainties have been described in the
Company's filings with the Commission. See "Incorporation of Certain Documents
by Reference."
 
     While presented with numerical specificity, the projections are based upon
numerous estimates and assumptions that are inherently subject to significant
business, economic, industry and competitive uncertainties and contingencies,
all of which are difficult to predict and many of which are beyond the Company's
control. Certain assumptions on which the projections were based related to the
achievement of strategic goals, objectives and targets over the applicable
periods that are more aggressive than recent historical results. Further
assumptions were made concerning portfolio revenue degradation resulting from
competitive pricing pressures, portfolio attrition from loss of existing
merchants and projected sales and revenue growth including the NationsBank
franchise. The forecast excludes transaction related costs and assumes reduced
reliance on third party processors in 1999 and beyond. There can be no assurance
that the projected results would be realized or that actual results would not be
significantly higher or lower than those predicted. While the
 
                                       26
<PAGE>   31
 
projections were prepared in good faith, no assurance can be made regarding
future events. Therefore, such projections cannot be considered a reliable
predictor of future operating results, and this information should not be relied
upon as such. Additionally, the financial projections do not reflect revised
prospects for the Company, changes in general business and economic conditions,
or any other transaction or event that has occurred or may occur and that was
not anticipated at the time such information was prepared. The projections were
not prepared with a view toward public disclosure or complying with either the
published guidelines of the Commission regarding projections or forecasts or the
American Institute of Certified Public Accountants' Guide for Prospective
Financial Statements. The projections do not purport to present operations in
accordance with generally accepted accounting principles, and the Company's
independent auditors have not examined, compiled or performed any procedures
regarding these projections, and accordingly, assume no responsibility for them.
Holders of Class A Common Stock are cautioned not to place undue reliance on the
projections.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Board of Directors of the Company
with respect to the Merger, stockholders should be aware that certain members of
the Special Committee and the Board of Directors and certain executive officers
of the Company may have certain interests in the Merger that are in addition to
or are different from the interests of stockholders of the Company generally.
Certain directors and executive officers of the Company, including the members
of the Special Committee, own Class A Common Stock. See "Security Ownership of
Certain Beneficial Owners and Management." Certain directors and executive
officers of the Company, including the members of the Special Committee, own
shares of restricted Class A Common Stock and/or options to purchase shares of
Class A Common Stock, the cancellation and conversion of which is provided for
in the Merger Agreement. See "The Merger -- Treatment of Options and Other
Company Stock-Based Awards" and "Security Ownership of Certain Beneficial Owners
and Management." Certain directors and executive officers of the Company also
are employees of BankAmerica. Certain directors and executive officers of the
Company participate in BankAmerica's employee benefit plans, including health
and retirement plans. Nominees for the Company's Board of Directors are
recommended by the Company's Board of Directors, four of whom are current or
former employees of BankAmerica. As provided in the Merger Agreement,
BankAmerica and/or the Surviving Corporation will provide certain
indemnification and insurance in favor of the current and former directors and
executive officers of the Company. See "The Merger -- Indemnification."
 
     The Board of Directors of the Company has authorized the payment of a
special fee in the amount of $25,000 to each member of the Special Committee for
that member's service on the Committee.
 
     The Board of Directors of the Company was aware of the foregoing interests
and considered them, along with other matters, in approving and adopting the
Merger Agreement and the transactions contemplated thereby.
 
                                   THE MERGER
 
     The following is a brief summary of certain provisions of the Merger
Agreement, which is attached as Annex I to this Proxy Statement. The Merger
Agreement is incorporated herein by reference. This summary does not purport to
be complete and is qualified in its entirety by reference to the Merger
Agreement.
 
GENERAL
 
     The Merger Agreement provides that, at the Effective Time (as defined
below), Acquisition Corp. will be merged with and into the Company, the Company
will continue as the Surviving Corporation and the separate existence of
Acquisition Corp. will cease.
 
     Pursuant to the provisions of the Merger Agreement, as promptly as
practicable following the satisfaction or waiver of certain conditions
summarized herein, a certificate of merger will be prepared, executed and
verified by each of Acquisition Corp. and the Company and will be delivered to
the Secretary of State of the
 
                                       27
<PAGE>   32
 
State of Delaware for filing, as provided in the DGCL. The Merger will become
effective at the date and time specified in the certificate of merger filed with
the Secretary of State of the State of Delaware (such date and time, the
"Effective Time").
 
     Pursuant to the Merger Agreement, at the Effective Time, by virtue of the
Merger and without any action on the part of the holder thereof, each share of
Class A Common Stock (except shares as to which appraisal rights have been
perfected and shares held in the treasury of the Company) will be converted
solely into the right to receive $20.50 in cash, without interest thereon. Such
shares of Class A Common Stock will no longer be outstanding and will be
canceled. All of the shares of Common Stock held by BankAmerica or its
affiliates will, in the aggregate, be converted into and become the right to
receive, 100 shares of common stock of the Surviving Corporation.
 
     Holders of shares of Class A Common Stock who do not vote to approve and
adopt the Merger Agreement and who otherwise strictly comply with the provisions
of the DGCL regarding statutory appraisal rights have the right to seek a
determination of the fair value of their shares of Class A Common Stock and
payment in cash therefor in lieu of the Merger Consideration to which they would
otherwise be entitled. See "-- Appraisal Rights."
 
     As a result of the foregoing, at the Effective Time, the Company will
become a wholly owned subsidiary of the Bank, itself a wholly owned subsidiary
of BankAmerica. As a result of the Merger, holders of certificates formerly
evidencing shares of Class A Common Stock will cease to have any equity interest
in the Company.
 
     Promptly after the Effective Time, a letter of transmittal will be mailed
by the Exchange Agent to each holder of record of Class A Common Stock
immediately prior to the Effective Time to be used in forwarding such holder's
certificates evidencing such shares for surrender and exchange for the Merger
Consideration to which such holder has become entitled. After receipt of the
letter of transmittal, each holder of certificates formerly representing Class A
Common Stock should surrender such certificates together with the letter of
transmittal duly executed, and any other required documents as set forth in the
letter of transmittal, to the Exchange Agent, and each such holder will receive
in exchange the Merger Consideration to which such holder is entitled. The
letter of transmittal will be accompanied by instructions specifying other
details of the exchange. STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES
UNTIL THEY RECEIVE THE LETTER OF TRANSMITTAL. Thereafter, the stockholder will
receive as promptly as practicable in exchange therefor cash in an amount equal
to the product of the number of shares of Class A Common Stock formerly
represented by such stockholder's certificate(s) and $20.50. No interest will be
paid on the cash payable upon surrender of such certificate(s).
 
     After the Effective Time, each certificate formerly representing Class A
Common Stock, until surrendered and exchanged, will be deemed for all purposes
to evidence only the right to receive the Merger Consideration for each share of
Class A Common Stock represented.
 
     After the Effective Time, there will be no transfers of shares of Class A
Common Stock on the stock transfer books of the Company. If, after the Effective
Time, certificates theretofore representing shares of Class A Common Stock are
presented for transfer, they will be canceled and exchanged for the Merger
Consideration pursuant to the terms of the Merger Agreement.
 
     No transfer taxes will be payable in connection with any such payment for
shares of Class A Common Stock, except that if the check for such payment is to
be delivered to a person other than the person in whose name the certificates
surrendered are registered, the person requesting delivery of the check must,
prior to the delivery thereof, either (a) pay to the Exchange Agent any
resulting transfer taxes or other taxes or (b) establish to the satisfaction of
the Exchange Agent that such tax has been paid or is not applicable.
 
     Notwithstanding the foregoing, neither the Exchange Agent nor any party to
the Merger Agreement will be liable to any holder of stock certificates for any
amount paid to a public official pursuant to any applicable abandoned property,
escheat or similar law. Except as otherwise indicated in the immediately
preceding paragraph, the Company will pay all charges and expenses, including
those of the Exchange Agent, in connection with the exchange of stock
certificates for the Merger Consideration.
 
                                       28
<PAGE>   33
 
     Notwithstanding anything in the Merger Agreement to the contrary, shares of
Class A Common Stock that are issued and outstanding immediately prior to the
Effective Time and that are held by stockholders who have not voted such shares
in favor of the Merger and who have complied with the requirements of DGCL
Section 262 shall represent only the right to receive payment for such shares as
provided in the DGCL, and shall not be converted into the Merger Consideration,
unless such holder shall fail to perfect or shall effectively withdraw or lose
such stockholder's right to receive payment for such shares under the DGCL. See
"-- Appraisal Rights." If such holder shall have so failed to perfect or shall
have effectively withdrawn or lost such right, such stockholder's shares of
Class A Common Stock thereupon will be deemed, as of the Effective Time, to be
converted into the Merger Consideration.
 
     The Merger Agreement also provides that the Certificate of Incorporation of
the Surviving Corporation shall, at the Effective Time, be amended to read in
its entirety as set forth in Exhibit A to the Merger Agreement. At the Effective
Time, the Bylaws of the Surviving Corporation will be the Bylaws of Acquisition
Corp. as in effect immediately prior to the Effective Time. In addition, the
Merger Agreement provides that the officers of the Company at the Effective Time
will be, except as provided in the Merger Agreement, the officers of the
Surviving Corporation. The directors of the Company at the Effective Time shall
be those individuals designated by BankAmerica prior to the Effective Time.
 
CERTAIN EFFECTS OF THE MERGER
 
     Following the Merger, BankAmerica will indirectly own 100% of the Surviving
Corporation's outstanding capital stock and the stockholders of Class A Common
Stock immediately prior to the Merger will cease to have any ownership interests
in the Company or rights of stockholders (other than statutory appraisal rights,
in the case of those stockholders who perfect such rights under Delaware law).
The holders of Class A Common Stock will no longer benefit from any increase in
the value of the Company or any payment of dividends on the Common Stock of the
Company and will no longer bear the risk of any decrease in the value of the
Company.
 
     As a result of the Merger, the Class A Common Stock of the Company will
cease to be quoted on the NYSE and the Company will no longer be required to
file periodic reports with the Commission.
 
REPRESENTATIONS AND WARRANTIES
 
     The Merger Agreement contains various representations and warranties by
BankAmerica, Acquisition Corp. and/or the Company relating to, among other
things: (a) the organization and similar corporate matters of BankAmerica, the
Company and certain of their subsidiaries; (b) the capital structure of the
Company and the ownership of Acquisition Corp. by BankAmerica; (c) the
authorization, execution, delivery, performance and enforceability of the Merger
Agreement and related matters; (d) required consents and approvals of
governmental authorities, or conflicts under certificates of incorporation,
bylaws or material agreements, or material violations of law as a result of the
consummation of the transactions contemplated by the Merger Agreement; (e) the
accuracy of information supplied by the Company and BankAmerica in connection
with this Proxy Statement; and (f) absence of material violations of law.
 
CERTAIN COVENANTS
 
     In the Merger Agreement, the Company has agreed, among other things, that,
through the Effective Time and except as expressly contemplated or permitted by
the Merger Agreement or as otherwise consented to by BankAmerica, the Company
and any of its subsidiaries will, with certain exceptions, carry on their
business in the usual, regular and ordinary course in substantially the same
manner as heretofore conducted and will not (a) declare, set aside or pay any
dividend on or make any other distribution in respect of any of its capital
stock or split, combine or reclassify any shares of its capital stock, or
repurchase, redeem or otherwise acquire any shares of capital stock or voting
debt or any securities convertible into or rights to acquire its capital stock
or effect certain other changes in its capitalization; (b) issue, deliver or
sell, or authorize or propose the issuance, delivery or sale of, any shares of
its capital stock, or any rights, warrants, calls, subscriptions, options or
convertible or similar securities, subject to certain exceptions; (c) engage in
material acquisitions; (d) sell, lease, license, encumber or otherwise dispose
of material assets except in the ordinary
 
                                       29
<PAGE>   34
 
course of business consistent with past practice; (e) incur indebtedness for
borrowed money or guarantee any such indebtedness other than in the ordinary
course of business consistent with past practice; (f) make any change in
accounting principles or practices, subject to certain exceptions; (g) enter
into, adopt, amend (except as required by law) or terminate any employee benefit
plan or certain other arrangements and agreements, subject to certain
exceptions; (h) take any action or fail to take any action that would or would
be reasonably likely to result in any of its representations and warranties
becoming untrue such that any of the conditions to the Merger would not be
satisfied; (i) pay, discharge, settle or satisfy any claims, liabilities or
obligations, subject to certain exceptions; (j) except in the ordinary course of
business consistent with past practice or as required by the Merger Agreement,
modify, amend or terminate any material contract, lease or agreement to which
the Company or such subsidiary is a party, subject to certain exceptions; and
(k) amend or propose to amend its Certificate of Incorporation or Bylaws.
 
     In the Merger Agreement, the Company also agreed that it will not, and that
it will use its reasonable best efforts to cause its officers, directors, agents
and employees not to, initiate, knowingly encourage or solicit, directly or
indirectly, the making of any proposal or offer (an "Acquisition Proposal") to
acquire all or a substantial part of the business and properties or capital
stock of the Company, whether by merger, purchase of securities or assets,
tender offer or otherwise (any such transaction is referred to as an
"Acquisition Transaction"), or participate in any discussions or negotiations
regarding, or furnish to any other person, any information with respect to an
Acquisition Proposal. The Company may furnish or cause to be furnished
information subject to a confidentiality agreement in a form substantially
similar to that previously executed by BankAmerica and, in response to an
Acquisition Proposal, issue a communication to its stockholders of a type
contemplated by applicable securities laws or otherwise communicate the Board of
Director's position with respect to such Acquisition Proposal to the Company's
stockholders. The Company has agreed promptly to inform BankAmerica of the
material terms of any Acquisition Proposal that it receives.
 
     In the Merger Agreement, the Company agreed, among other things, (i) to
convene a meeting of its stockholders to be held as promptly as practicable for
the purpose of voting upon the Merger Agreement; (ii) to afford representatives
of BankAmerica access to the Company's properties, books, contracts, records and
information; and (iii) through its Board of Directors, subject to fiduciary
requirements of applicable law, to recommend that the stockholders approve the
Merger Agreement; provided, however, that at any time prior to the Meeting
either or both of the Special Committee or the Board of Directors, may revoke,
modify or qualify its recommendation with respect to the Merger Agreement if
they shall determine, in good faith (after consultation with legal counsel),
that failure so to do would create a material risk of liability for breach of
their fiduciary duties. In the Merger Agreement, the Company and BankAmerica
agreed to prepare and file with the Commission this Proxy Statement. BankAmerica
has agreed that at any meeting of the Company's stockholders convened to vote on
the Merger Agreement (and at any adjournment or postponement thereof), all of
the shares of Class B Common Stock will be voted in favor of the Merger
Agreement, provided that the recommendation of the Special Committee shall not
have been revoked, modified or qualified in a manner adverse to BankAmerica.
 
     In the Merger Agreement, the Company and BankAmerica agreed that, for the
purposes of the Merger Agreement, no representation or warranty of the Company
contained in the Merger Agreement shall be deemed to be untrue, incorrect or
breached if (A) the failure of the representation or warranty to be true or
correct, or the breach of the representation or warranty, results from any act
or omission of (1) BankAmerica, (2) any person or persons acting at the request
or direction of BankAmerica, or (3) any one or more officer(s), director(s),
employee(s) or representative(s) of BankAmerica or its affiliates (including,
without limitation, any one or more member(s) of the Board of Directors of the
Company other than the members of the Special Committee (each such officer,
director, employee and representative being referred to in the Merger Agreement
as a "BankAmerica Nominee")); or (B) any facts or circumstances that constitute
or give rise to the untruth or inaccuracy in (or breach of) the representation
or warranty were known to BankAmerica or any BankAmerica Nominee at the time
such representation or warranty was made by the Company. The Company and
BankAmerica also agreed that, for purposes of the Merger Agreement, the Company
shall not be deemed to have breached any of its covenants or agreements
contained in the Merger Agreement if (A) the breach of the covenant or agreement
results from any act or omission of (1) BankAmerica, (2) any
 
                                       30
<PAGE>   35
 
person or persons acting at the request or direction of BankAmerica, or (3) any
one or more BankAmerica Nominee(s); or (B) any facts or circumstances that
constitute or give rise to such breach were known to BankAmerica or any
BankAmerica Nominee at the time of or prior to the occurrence of such breach and
if, after BankAmerica shall have become aware of such facts and circumstances,
BankAmerica shall have failed promptly to advise the Special Committee in
writing of such facts or circumstances. For purposes of the two preceding
sentences, BankAmerica shall be deemed to have knowledge of a fact or
circumstance or act or omission if such fact or circumstance or act or omission
was formally considered at a meeting of the Board of Directors of the Company at
which any BankAmerica Nominee was present throughout such consideration or
included in any written materials provided to any such BankAmerica Nominee.
 
TREATMENT OF OPTIONS AND OTHER COMPANY STOCK-BASED AWARDS
 
     The Merger Agreement provides that, as soon as practicable following the
date thereof, the Board of Directors of the Company (or, if appropriate, any
committee administering the Company's Long-Term Incentive Plan and Non-Employee
Director Stock Plan (collectively, the "Stock Plans")) shall adopt such
resolutions or take such other actions as are required to provide for the
cancellation of all outstanding options issued under the Stock Plans ("Company
Options") upon the Effective Time, in exchange for a cash payment of an amount
equal to (i) the excess, if any, of (x) the Merger Consideration per share over
(y) the exercise price per share of such Company Option, multiplied by (ii) the
number of shares of Class A Common Stock subject to such Company Option for
which such Company Option shall not theretofore have been exercised, whether or
not then vested and exercisable. The Merger Agreement further provides that,
prior to the Effective Time, the Company shall use its commercially reasonable
efforts to (A) obtain any necessary consents from holders of Company Options,
and (B) make any amendments to the terms of such options that are necessary to
give effect to the transactions contemplated by the Merger Agreement; provided,
however, that the failure by the Company to obtain any such consents or to make
any such amendments or the failure of the Company's Board of Directors to take
any such action shall not give rise to a right of termination by BankAmerica or
Acquisition Corp. under any provision of the Merger Agreement or result in a
failure of condition to BankAmerica's or Acquisition Corp.'s obligation to
consummate the transactions contemplated by the Merger Agreement. The Merger
Agreement further provides that each outstanding share of unvested restricted
Class A Common Stock issued pursuant to a Stock Plan (each, a "Restricted
Share") shall, immediately prior to the Effective Time, be canceled and be
converted into, and become the right to receive, the Merger Consideration. The
amount otherwise payable in respect of certain Restricted Shares to certain
senior executive officers of the Company shall be distributed to such officers
on a deferred basis.
 
     The Merger Agreement also requires that the Board of Directors of the
Company (or, if appropriate, any committee administering the Stock Plans) adopt
such resolutions or take such actions as are required to terminate the Stock
Plans as of the Effective Time, to delete as of the Effective Time the provision
in any other benefit plan of the Company providing for the issuance, transfer or
grant of any capital stock of the Company or any interest in respect of any
capital stock of the Company and to ensure that following the Effective Time no
holder of a Company Option or any participant in any Stock Plan or other Company
benefit plan shall have any right thereunder to acquire any capital stock of the
Company or the Surviving Corporation.
 
INDEMNIFICATION
 
     The Merger Agreement provides that: (a) for a period of six years from the
Effective Time, the Surviving Corporation will maintain all rights to
indemnification (including with respect to the advancement of expenses incurred
in the defense of any action or suit) existing on the date of the Merger
Agreement in favor of the current and former directors and executive officers of
the Company as provided in the Company's Certificate of Incorporation and Bylaws
or otherwise, in each case as in effect on the date of the Merger Agreement; (b)
the Certificate of Incorporation and Bylaws of the Surviving Corporation will
not be amended to reduce or limit such rights of indemnity; and (c) for a period
of six years from the Effective Time, the Surviving Corporation will indemnify
such persons to the fullest extent possible under its Certificate of
Incorporation, its Bylaws and applicable law against all losses, damages,
liabilities or claims made against them arising from their service in such
capacity prior to and including the Effective Time, to at least the same extent
as such persons currently are required to be indemnified pursuant to the
Company's Certificate of Incorporation and
                                       31
<PAGE>   36
 
Bylaws. The Merger Agreement also provides that, for a period of six years from
the Effective Time, BankAmerica shall, to the extent permitted by applicable
law, indemnify and hold harmless each current and former director and executive
officer against and from any costs, fees, and expenses (including reasonable
attorneys' fees), judgments, fines, losses, claims, damages, liabilities, and
amounts paid in settlement in connection with any lawsuit, court action or other
court proceeding, claim, or investigation, to the extent that such legal
proceeding arises out of or pertains to (1) any action or omission or alleged
action or omission in his or her capacity as a director or executive officer, or
as employee or agent, of the Company or (2) any of the transactions contemplated
by the Merger Agreement. The Merger Agreement also provides that, for a period
of six years from the Effective Time, the Surviving Corporation (or BankAmerica
on its behalf) will cause to be maintained in effect, at no expense to the
beneficiaries thereof, directors' and officers' liability insurance providing at
least the same coverage with respect to the Company's officers and directors as
the policies, if any, maintained from time to time by or on behalf of
BankAmerica with respect to its directors and officers or, if broader in scope,
the policies maintained by the Company as of the date of the Merger Agreement;
provided, however, that the aggregate annual premium payable therefor shall not
exceed 150% of the aggregate annual premium payable for such directors' and
officers' liability insurance policies currently in effect (it being understood
that if the aggregate annual premium of such insurance coverage exceeds the
amount referred to in this sentence, BankAmerica shall be obligated to obtain a
policy with the broadest coverage available for a cost not exceeding such
amount).
 
TAIWAN BUSINESS
 
     On December 9, 1998, BankAmerica announced a plan to divest certain of the
assets and businesses of BankAmerica and its affiliates which are located in
various countries in Asia, including possibly certain assets and businesses
located in the Republic of China. The Merger Agreement provides that the assets
and business of the Company located in the Republic of China (the "Taiwan
Business") may, at the election of BankAmerica, be included within certain
assets and businesses of BankAmerica or its affiliates which may be the subject
of divestitures by BankAmerica or its affiliates after the date of the Merger
Agreement. BankAmerica has agreed to consult with the Company in connection with
such divestitures and has further agreed that the Company shall be entitled to
receive its allocable proportion of the consideration received by BankAmerica
and its affiliates for such Asian assets and businesses, of which the Taiwan
Business shall be a part, such allocation to be determined in good faith by
BankAmerica. In the event that the Merger Agreement shall be terminated for any
reason and prior to or thereafter the divestiture of the Taiwan Business shall
be consummated on terms which result in the consideration therefor receivable
under the Merger Agreement by the Company being less than the market value of
the securities of the Company issued in connection with the acquisition thereof,
determined in the manner consistent with the valuation used at the time of such
acquisitions, BankAmerica shall promptly pay to the Company the difference
between such market value and the consideration therefor receivable. For
additional information, see "Certain Transactions and Relationships Between
BankAmerica and the Company -- General."
 
CONDITIONS
 
     The respective obligations of BankAmerica and Acquisition Corp., on the one
hand, and the Company, on the other hand, to effect the Merger are subject to
the following conditions: (a) no statute, rule, regulation, executive order,
decree, preliminary or permanent injunction or restraining order shall have been
enacted, entered, promulgated or enforced by any United States federal or state
court of competent jurisdiction or other United States governmental entity that
prohibits the consummation of the Merger; and (b) the representations and
warranties of the other party set forth in the Merger Agreement shall be true
and correct, and the other party shall have performed all obligations required
to be performed by it under the Merger Agreement, in all respects; provided that
in determining the accuracy of such representations and warranties no effect
shall be given to any qualification or exception relating to materiality
contained therein and a party's representations and warranties shall be deemed
to be true and correct unless any breaches thereof, individually or in the
aggregate, would have or would be reasonably likely to have a material adverse
effect on the Company, as to the condition to BankAmerica's and Acquisition
Corp.'s obligation to close the Merger, or on BankAmerica and Acquisition Corp.,
as to the condition of the Company's obligation to close the Merger; and
provided,
                                       32
<PAGE>   37
 
further, that any failure by the Company to perform its obligations must not
have and must not be reasonably likely to have a material adverse effect on the
Company or on the economic consequences to BankAmerica of the transactions
contemplated by the Merger Agreement.
 
TERMINATION
 
     The Merger Agreement may be terminated and the Merger abandoned at any time
prior to the Effective Time, whether before or after approval of the matters
presented in connection with the Merger by the stockholders of the Company: (a)
by mutual consent of the parties thereto; (b) by either BankAmerica, Acquisition
Corp. or the Company (i) if there has been a breach of any representation,
warranty, covenant or agreement on the part of any other party which breach
shall have had a material adverse effect on such party and shall not have been
cured prior to the earlier of (x) 30 days following notice of such breach or (y)
April 30, 1999, or (ii) if any permanent injunction or other order of a United
States federal or state court or other competent United States governmental
entity preventing the consummation of the Merger shall have become final and
non-appealable; (c) by either BankAmerica, Acquisition Corp. or the Company if
the Merger shall not have been consummated before April 30, 1999 (unless such
party's breach is the cause or resulted in the failure of the Merger to occur);
(d) by the Company if the Merger shall not have been approved by the holders of
a majority of the outstanding shares of Common Stock of the Company entitled to
vote thereon at the Meeting; or (e) by BankAmerica if the Special Committee

manner adverse to BankAmerica, its recommendation in favor of the adoption and
approval of the Merger Agreement or the approval of the Merger.
 
EFFECT OF TERMINATION
 
     In the event of any termination of the Merger Agreement by either
BankAmerica, Acquisition Corp. or the Company, the Merger Agreement will become
void and there will be no liability or obligation on the part of BankAmerica,
Acquisition Corp., the Company or their respective officers, directors or
stockholders except to the extent that such termination results from the willful
breach by a party of any of its representations, warranties, covenants or
agreements set forth in the Merger Agreement.
 
AMENDMENT AND WAIVER

for their respective benefit contained in the Merger Agreement.
 
APPROVAL BY SPECIAL COMMITTEE

law, (a) the approval of a majority of the members of the Special Committee
shall be required to authorize (i) any termination of the Merger Agreement by
the Company, (ii) any agreement by the Company to amend the Merger Agreement,
(iii) any extension of time for the performance of any of the obligations or
other acts of BankAmerica or Acquisition Corp., or (iv) any waiver of compliance
with or any waiver of any breach of any of the representations, warranties,
covenants or conditions contained in the Merger Agreement for the benefit of the
Company; and (b) the authorization of any such action by a majority of the
Special Committee shall constitute authorization of such action by the Board of
Directors of the Company.
 
ACCOUNTING TREATMENT
 
     The acquisition of the Company's public shares in the Merger will be
accounted for by BankAmerica as a "purchase" under generally accepted accounting
principles.
 
                                       33

CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Under currently applicable law, the following are the material United
States federal income tax considerations generally applicable to the Merger. The
tax treatment described herein may vary depending upon each stockholder's
particular circumstances and tax position. Certain stockholders (including
insurance companies, tax-exempt organizations, financial institutions or
broker-dealers, foreign corporations, persons who are not citizens or residents
of the United States, stockholders who do not hold their shares as capital
assets and stockholders who have acquired their existing stock upon the exercise
of options or otherwise as compensation) may be subject to special rules not
discussed below. No ruling from the Internal Revenue Service ("IRS") will be
sought with respect to the federal income tax consequences discussed herein and,
accordingly, there can be no assurance that the IRS will agree with the
conclusions stated herein. The discussion below is based upon the provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), and regulations,
rulings and judicial decisions thereunder as of the date hereof, and such
authorities may be repealed, revoked or modified so as to result in U.S. federal
income tax consequences different from those discussed below. In addition, this
discussion does not consider the effect of any applicable foreign, state, local
or other tax laws. Each stockholder should consult his or her own tax advisor as
to the particular tax consequences to him or her of the Merger, including the
applicability and effect of any foreign, state, local or other tax laws.
 
     Characterization of the Merger for U.S. Federal Income Tax Purposes.  For
U.S. federal income tax purposes, the transitory existence of Acquisition Corp.
will be disregarded and the Merger treated for such purposes as the purchase by
BankAmerica of outstanding shares of Class A Common Stock at $20.50 per share.
 
     Stockholders Receiving Cash in the Merger.  Each Company stockholder
receiving cash in the Merger will recognize either capital gain or loss
(assuming the Company stock is held by such stockholder as a capital asset at
the Effective Time) equal to the difference between the amount realized on his
or her deemed sale of Company stock to BankAmerica and the stockholder's
adjusted tax basis in such Company stock. Such gain or loss generally will be
long-term capital gain or loss if the Company stock is held as a capital asset
by the stockholder for more than one year at the Effective Time.
 
     Dissenting Stockholders.  For federal income tax purposes, dissenting
stockholders receiving cash as a result of exercise of their rights of appraisal
will be treated as having had their shares of Class A Common Stock redeemed by
the Company in exchange for that cash. As the Company will be indirectly wholly
owned by BankAmerica following the Merger, the deemed redemption of a dissenting
stockholder's shares of Company stock should be treated as a sale of such stock
through application of the "complete termination of interest" rules under
section 302 of the Code so that the federal income tax consequences to
dissenting stockholders should be as described under "Stockholders Receiving
Cash in the Merger," above.
 
     Backup Withholding.  The Company or the Exchange Agent will be required to
withhold 31% of the gross proceeds payable to a stockholder or other payee in
the Merger unless the stockholder or payee provides, in a properly completed
substitute Form W-9 included with the transmittal letter, the stockholder's
taxpayer identification number and certifies under penalties of perjury that
such number is correct and that the stockholder is not subject to backup
withholding, unless an exemption applies under applicable law and regulations.
Therefore, unless such an exemption exists and is demonstrated in a manner
satisfactory to the Company or the Exchange Agent, in accordance with the
instructions that will accompany the substitute Form W-9, each stockholder
should complete and sign the substitute Form W-9 that will be made available to
the stockholder with the transmittal letter, so as to provide the information
and certification necessary to avoid backup withholding.
 
     Foreign Stockholders.  The following is a general discussion of certain
U.S. federal income tax consequences of the Merger to foreign stockholders. For
this purpose, a foreign stockholder is any person who is, for U.S. federal
income tax purposes, a foreign corporation, a nonresident alien individual, a
foreign partnership or a foreign estate or trust.
 
                                       34
<PAGE>   39
 
     In general, any gain realized upon a foreign stockholder's sale of shares
of Class A Common Stock will not be subject to U.S. federal income tax unless
(i) the gain is effectively connected with a trade or business in the United
States of the foreign stockholder or (ii) in the case of a foreign stockholder
who is an individual, such individual is present in the United States for 183
days or more in the taxable year of the sale and certain other conditions are
met. If the gain is effectively connected with the conduct of a U.S. trade or
business, the foreign stockholder will generally be subject to U.S. federal
income tax on such gain on a net income basis in the same manner as if it were a
U.S. taxpayer. In addition, if the foreign stockholder is a foreign corporation,
it may be subject to a branch profits tax equal to 30% (or applicable lower tax
treaty rate) on its effectively connected earnings and profits for the taxable
year, subject to adjustments. For this purpose, effectively connected gain from
the sale of shares of Class A Common Stock would be included in such foreign
corporation's earnings and profits.
 
     The Company or the Exchange Agent will be required to withhold 31% of the
gross proceeds payable to a foreign stockholder in the Merger unless the foreign
stockholder (i) provides his name and address, and certifies, under penalties of
perjury, that he is not a U.S. person (which certification may be made in a
properly completed substitute Form W-8 included with the transmittal letter or
in Form W-8BEN) or (ii) a financial institution holding the shares of Class A
Common Stock on behalf of the beneficial owner certifies, under penalties of
perjury, that such statement has been received by it and furnishes a paying
agent with a copy thereof. Therefore, unless an exemption exists and is
demonstrated in a manner satisfactory to the Company or the Exchange Agent, in
accordance with the instructions that will accompany the substitute Form W-8,
each foreign stockholder should complete and sign the substitute Form W-8 that
will be made available to stockholders with the transmittal letter, so as to
provide the information and certification necessary to avoid backup withholding.
Beneficial owners holding shares of Class A Common Stock through others are
urged to consult their tax advisors regarding application of the U.S. backup
withholding rules to their circumstances.
 
     ALTHOUGH THE FOREGOING ARE THE MATERIAL U.S. FEDERAL INCOME TAX
CONSIDERATIONS GENERALLY APPLICABLE TO THE MERGER, THE DISCUSSION DOES NOT
ADDRESS EVERY FEDERAL INCOME TAX CONCERN WHICH MAY BE APPLICABLE TO A PARTICULAR
STOCKHOLDER. EACH STOCKHOLDER IS URGED TO CONSULT SUCH STOCKHOLDER'S OWN TAX
ADVISOR TO DETERMINE THE TAX CONSEQUENCES TO SUCH STOCKHOLDER, IN THE LIGHT OF
HIS OR HER PARTICULAR CIRCUMSTANCES, OF THE DISPOSITION OF SHARES OF CLASS A
COMMON STOCK PURSUANT TO THE MERGER.
 
APPRAISAL RIGHTS
 
     THE FOLLOWING SUMMARY DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF
APPRAISAL RIGHTS UNDER THE DGCL AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
SECTION 262 OF THE DGCL, WHICH IS ATTACHED AS ANNEX III TO THIS PROXY STATEMENT.
 
     Record holders of Class A Common Stock are entitled to appraisal rights
under Section 262 of the DGCL in connection with the Merger. The following
provides a discussion of the material provisions of the law pertaining to
appraisal rights under the DGCL. Such discussion is not a complete statement of
such law and is qualified in its entirety by the full text of Section 262 which
is presented in its entirety as Annex III to this Proxy Statement. Except as set
forth herein, stockholders of the Company will not be entitled to appraisal
rights in connection with the Merger. All record holders of Class A Common Stock
who wish to exercise their appraisal rights with respect to such shares must
comply with the procedures of Section 262 of the DGCL.
 
     Section 262.  Under the DGCL, record holders of shares of Class A Common
Stock who follow the procedures set forth in Section 262 and who have not voted
in favor of the Merger will be entitled to have their shares of Class A Common
Stock appraised by the Delaware Court of Chancery and to receive payment of the
"fair value" of such shares, exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest, if any, as determined by such court. A person having a
 
                                       35
<PAGE>   40
 
beneficial interest in shares of Class A Common Stock held of record in the name
of another person, such as a broker or nominee, must act promptly to cause the
record holder to follow the steps summarized below properly and in a timely
manner to perfect appraisal rights.
 
     Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the Meeting, not less than 20 days
prior to the meeting, the company must notify each of the record holders of
shares of capital stock at the close of business on the record date for such
meeting that such appraisal rights are available and include in each such notice
a copy of Section 262. This Proxy Statement constitutes such notice and the
applicable statutory provision of the DGCL is attached to this Proxy Statement
as Annex III. Any stockholder who wishes to exercise appraisal rights should
review the following discussion and Annex III carefully because the failure to
timely and properly comply with the procedures specified in Section 262 will
result in the loss of appraisal rights under the DGCL.
 
     A record holder of shares of Class A Common Stock wishing to exercise
appraisal rights must deliver to the Company, before the taking of the vote on
the Merger at the Meeting, a written demand for appraisal of such holder's
shares of Class A Common Stock and such shares must not be voted in favor of
adoption of the Merger Agreement. Such written demand must reasonably inform the
Company of the identity of the stockholder of record and that such record
stockholder intends thereby to demand appraisal of such shares. In addition, a
holder of shares of Class A Common Stock wishing to exercise appraisal rights
must hold of record such shares on the date the written demand for appraisal is
made and must continue to hold of record such shares through the Effective Time.
Accordingly, a holder of shares who is the record holder of shares on the date
the written demand for appraisal is made, but who thereafter transfers such
shares prior to the consummation of the Merger, will lose any right to appraisal
in respect of such shares. A holder of shares who votes against adoption of the
Merger Agreement will not be deemed to have satisfied the notice requirement of
such holder with respect to appraisal rights merely by so voting. The written
demand for appraisal must be in addition to and separate from any proxy or vote
abstaining from or against adoption of the Merger Agreement.
 
     Only a holder of record of shares of Class A Common Stock is entitled to
assert appraisal rights for such shares registered in that holder's name. A
demand for appraisal should be executed by or on behalf of the holder of record
fully and correctly, as the holder's name appears on the stock certificates.
 
     If shares of Class A Common Stock are owned of record in a fiduciary
capacity, such as by a trustee, guardian or custodian, execution of the demand
should be made in that capacity, and if the shares of Class A Common Stock are
owned of record by more than one person, as in a joint tenancy or tenancy in
common, the demand should be executed by or on behalf of all joint owners. An
authorized agent, including one or more joint owners, may execute a demand for
appraisal on behalf of a holder of record; however, the agent must identify the
record owner or owners and expressly disclose the fact that, in executing the
demand, he or she is acting as agent for such owner or owners. A record holder
such as a broker who holds shares of Class A Common Stock as nominee for several
beneficial owners may exercise appraisal rights with respect to the shares of
Class A Common Stock held for one or more beneficial owners while not exercising
such rights with respect to the shares of Class A Common Stock held for other
beneficial owners. In such case, the written demand should set forth the number
of shares of Class A Common Stock as to which appraisal is sought and the number
of shares of Class A Common Stock held in the name of the record owner. When no
number of shares is expressly mentioned, the demand will be presumed to cover
all shares of Class A Common Stock held in the name of the record owner. Holders
of Class A Common Stock who hold their shares in brokerage accounts or other
nominee forms and who wish to exercise appraisal rights are urged to consult
with their brokers to determine the appropriate procedures for the making of a
demand for appraisal by such nominee.
 
     All written demands for appraisal of shares of Class A Common Stock should
be sent or delivered to the Company, c/o Bank of America National Trust and
Savings Association, 555 California Street, 6th Floor, San Francisco, California
94104, Attention: Corporate Secretary, and must be received before the taking of
the vote on the Merger by holders of Common Stock at the Meeting.
 
     Within ten days after the Effective Time, the Company, as the Surviving
Corporation, must send a notice as to the effectiveness of the Merger to each
person who has satisfied the appropriate provisions of Section 262. Within 120
days after the Effective Time, but not thereafter, any holder of shares of Class
A
                                       36
<PAGE>   41
 
Common Stock who has satisfied the foregoing conditions and is otherwise
entitled to appraisal rights under Section 262, may file a petition in the
Delaware Court of Chancery demanding a determination of the fair value of the
shares of Class A Common Stock held by all such stockholders. If no such
petition is filed, appraisal rights will be lost for all stockholders who had
previously demanded appraisal of their shares of Class A Common Stock.
Stockholders seeking to exercise appraisal rights should assume that the
Surviving Corporation will not file a petition with respect to the appraisal of
the value of shares of Class A Common Stock and that the Surviving Corporation
will not initiate any negotiations with respect to the "fair value" of shares of
Class A Common Stock. Accordingly, stockholders who wish to exercise their
appraisal rights should regard it as their obligation to take all steps
necessary to perfect their appraisal rights in the manner prescribed in Section
262.
 
     Within 120 days after the Effective Time, any record holder of shares of
Class A Common Stock who has complied with the provisions of Section 262 will be
entitled, upon written request, to receive from the Surviving Corporation a
statement setting forth the aggregate number of shares of Class A Common Stock
not voted in favor of the Merger and with respect to which demands for appraisal
were received by the Company and the aggregate number of holders of such shares
of Class A Common Stock. Such statement must be mailed within ten days after a
written request therefor has been received by the Surviving Corporation or
within ten days after expiration of the time for delivery of demands for
appraisal under Section 262, whichever is later.
 
     If a petition for an appraisal is timely filed, at the hearing on such
petition, the Delaware Court of Chancery will determine which holders of shares
of Class A Common Stock are entitled to appraisal rights. The Delaware Court of
Chancery may require the holders of Class A Common Stock who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any holder of
shares of Class A Common Stock fails to comply with such direction, the Delaware
Court of Chancery may dismiss the proceedings as to such stockholder. Where
proceedings are not dismissed, the Delaware Court of Chancery will appraise the
shares of Class A Common Stock owned by such stockholders, determining the fair
value of such shares exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest, if any, to be paid upon the amount determined to be the fair value.
 
     Although the Special Committee believes that the Merger Consideration is
fair, no representation is made as to the outcome of the appraisal of fair value
as determined by the Delaware Court of Chancery, and holders of Class A Common
Stock should recognize that such an appraisal could result in a determination of
a value higher or lower than, or the same as, the Merger Consideration.
Moreover, BankAmerica does not anticipate offering more than the Merger
Consideration to any holder of Class A Common Stock exercising appraisal rights
and reserves the right to assert, in any appraisal proceeding, that, for
purposes of Section 262, the "fair value" of a share of Class A Common Stock is
less than the Merger Consideration. In determining "fair value," the Delaware
Court of Chancery is required to take into account all relevant factors. In
Weinberger v. UOP, Inc. the Delaware Supreme Court discussed the factors that
could be considered in determining fair value in an appraisal proceeding,
stating that "proof of value by any techniques or methods which are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered and that "[f]air price obviously requires
consideration of all relevant factors involving the value of a company." The
Delaware Supreme Court has stated that in making this determination of fair
value the court must consider market value, asset value, dividends, earnings
prospects, the nature of the enterprise and any other facts which could be
ascertained as of the date of the merger which throw any light on future
prospects of the merged corporation. Section 262 provides that fair value is to
be "exclusive of any element of value arising from the accomplishment or
expectation of the merger." In Cede & Co. v. Technicolor, Inc., the Delaware
Supreme Court stated that such exclusion is a "narrow exclusion [that] does not
encompass known elements of value," but which rather applies only to the
speculative elements of value arising from such accomplishment or expectation.
In Weinberger, the Delaware Supreme Court construed Section 262 to mean that
"elements of future value, including the nature of the enterprise, which are
known or susceptible of proof as of the date of the merger and not the product
of speculation, may be considered." In
 
                                       37
<PAGE>   42
 
addition, Delaware courts have decided that the statutory appraisal remedy,
depending on factual circumstances, may or may not be the exclusive remedy.
 
     The Court will also determine the amount of interest, if any, to be paid
upon the amounts to be received by persons whose shares of Class A Common Stock
have been appraised. The costs of the action may be determined by the Court and
taxed upon the parties as the Court deems equitable. The Court may also order
that all or a portion of the expenses incurred by any holder of shares of Class
A Common Stock in connection with an appraisal, including, without limitation,
reasonable attorneys' fees and the fees and expenses of experts utilized in the
appraisal proceeding, be charged pro rata against the value of all of the shares
of Class A Common Stock entitled to appraisal.
 
     Any holder of shares of Class A Common Stock who has duly demanded an
appraisal in compliance with Section 262 will not, after the Effective Time, be
entitled to vote his or her shares of Class A Common Stock for any purpose nor,
after the Effective Time, be entitled to the payment of dividends or other
distributions thereon (except dividends or other distributions payable to
holders of record of shares of Class A Common Stock as of a date prior to the
Effective Time).
 
     A holder of shares of Class A Common Stock will fail to perfect, or
effectively lose, the right to appraisal if no petition for appraisal is filed
within the time provided. If a stockholder delivers to the Surviving Corporation
a written withdrawal of his or her demand for an appraisal and an acceptance of
the Merger, within 60 days after the Effective Time or with the written approval
of the Surviving Corporation thereafter, then the right of such stockholder to
an appraisal will cease and such stockholder shall be entitled to receive the
Merger Consideration, without interest, as if he or she had not demanded
appraisal of his or her shares of Class A Common Stock. However, no appraisal
proceeding pending in the Court of Chancery will be dismissed as to any
stockholder without the approval of the Court, which approval may be conditioned
on such terms as the Court deems just.
 
     FAILURE TO STRICTLY COMPLY WITH THE PROCEDURES SET FORTH IN SECTION 262 OF
THE DGCL FOR PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE TERMINATION OR WAIVER
OF SUCH RIGHTS.
 
     The foregoing is a summary of certain of the provisions of Section 262 of
the DGCL and is qualified in its entirety by reference to the full text of such
Section, a copy of which is attached hereto as Annex III.
 
LITIGATION
 
     On October 27, 1998, two putative class actions entitled Crandon Capital
Partners v. Sharif M. Bayyari, et al., Civil Action No. 16734 (the "Crandon
Action"), and Gold Plate Holdings, Inc. v. Sharif M. Bayyari, et al., Civil
Action No. 16735 (the "Gold Plate Action"), were filed in the Court of Chancery
of the State of Delaware in and for New Castle County in connection with the
announcement by BankAmerica and the Company on October 22, 1998 (the
"Announcement") that BankAmerica was offering to acquire through merger each
outstanding share of Class A Common Stock for $15.50 per share, in cash (the
"Proposal"). A third putative class action, entitled Value Holdings, L.P. v.
Sharif M. Bayyari, et al., Civil Action No. 16755NC (the "Value Holdings
Action"), was filed on October 29, 1998 in the Court of Chancery of the State of
Delaware in and for New Castle County.
 
     The Crandon, Gold Plate and Value Holdings Actions, collectively referred
to herein as the "Stockholders' Litigation", each challenge the terms of the
Proposal, name as defendants certain present and former directors of the
Company, and allege that these individuals, as well as BankAmerica, breached
their fiduciary duty to the public stockholders of the Company in that
BankAmerica, through its control of the Company and taking advantage of the
purportedly depressed state of the market, acted unfairly toward such public
stockholders in making the Proposal which, in turn, is argued to represent
unfair and inadequate consideration tendered for the shares of Class A Common
Stock. The individuals named in the Stockholders' Litigation, as well as
BankAmerica and the Company, deny these allegations.
 
     The Stockholders' Litigation seeks to have the Merger enjoined or, if it is
consummated, to have it rescinded and to recover unspecified damages, fees and
expenses. Lead counsel has been designated by the plaintiffs and the several law
firms representing the plaintiffs in the Stockholders' Litigation.
                                       38
<PAGE>   43
 
     On December 22, 1998, counsel to BankAmerica, the Company and the other
defendants entered into a Memorandum of Understanding with lead counsel to the
plaintiffs in such actions for the settlement thereof. The Memorandum of
Understanding provides for a full and complete settlement of the Stockholders'
Litigation. Lead counsel, acting on behalf of all plaintiffs' counsel and their
clients in the Stockholders' Litigation, agreed to the proposed settlement,
based on the terms of the Merger Agreement after reviewing the matter with a
financial services consultant retained by plaintiffs' counsel in connection with
the litigation and conferring with counsel to BankAmerica regarding the
consideration being offered for the shares of Class A Common Stock. The proposed
settlement contemplated by the Memorandum of Understanding is subject to certain
additional discovery by plaintiffs' counsel and approval by the court. The
Memorandum of Understanding provides, among other things, that (i) the parties
agree that the increased cash consideration of $20.50 per share of Class A
Common Stock constitutes fair, adequate and reasonable consideration for such
shares and for the settlement of all claims which were raised or could have been
raised by plaintiffs in the Stockholders' Litigation and that BankAmerica took
into account the desirability of satisfactorily addressing the claims asserted
in the Stockholders' Litigation in agreeing to the increased consideration to be
paid for the shares of Class A Common Stock and that the pendency of the
Stockholders' Litigation and communications with plaintiffs' counsel were
contributive and influential factors in connection with the enhanced terms of
the Merger; (ii) the parties will agree upon and execute within 45 days of the
date of the Memorandum of Understanding an appropriate Stipulation of Settlement
(the "Stipulation") of all claims asserted in the Stockholders' Litigation and
all other claims arising out of or related in whole or in part to the Merger;
(iii) the Stipulation shall provide for the dismissal of all claims with
prejudice and without cost to any party, except as provided in the Memorandum of
Understanding, and will also provide for class certification of a class
consisting of all holders of shares of Class A Common Stock on any day during
the period from October 22, 1998 through and including the closing of the
Merger; (iv) the Stipulation will provide that all defendants have denied, and
continue to deny, that they have committed any violation of law; (v) plaintiffs
will provide for releases of claims against all defendants; (vi) the parties
will present the settlement to the court for hearing and approval as soon as
practicable and, following appropriate notice to members of the class, will use
their best efforts to obtain final court approval of the settlement and the
release and dismissal of the actions with prejudice against the plaintiffs in
the class; (vii) the Merger may be consummated prior to final court approval of
the settlement; (viii) subject to obtaining final court approval of the proposed
settlement and final dismissal with prejudice of the Stockholders' Litigation,
defendants will not oppose an application by plaintiffs' counsel in the
Stockholders' Litigation, acting through lead counsel, for an award of
attorneys' fees not to exceed $1.1 million and an award of actual documented
expenses not to exceed $50,000, which amounts are to be reviewed and approved by
the court for reasonableness. The Stipulation will also provide that any claim
for appraisal rights pursuant to the DGCL Section 262 shall not be released. See
"-- Appraisal Rights."

     The selected financial information included in the table below for each of
the five years in the period ended December 31, 1997 has been derived from and

(1) All data presented for the years ended December 31, 1997, 1996, 1995 and
    1994 include the historical results of the Asia Acquisitions. The
    acquisition of these entities has been accounted for as a
 
                                       40
<PAGE>   45
 
    reorganization of entities under common control. Prior to January 1, 1994,
    the Asian operations were fully integrated with the operations of
    BankAmerica in each of the respective countries. Certain amounts have been
    reclassified to conform with the current year presentation. Amounts
    reflected in this table may not foot due to rounding.
(2) On December 31, 1996, certain employees of the Company elected to exchange
    their employee stock options and restricted stock from BankAmerica for
    options and restricted stock of the Company. This employee stock exchange
    resulted in a one-time expense of $2.4 million.
(3) The earnings per common share amount has not been presented because it is
    the same as the diluted earnings per common share amount.
(4) Pro forma diluted earnings per common share for all periods presented has
    been calculated as if the initial offerings of Class A Common Stock had been
    completed on January 1, 1993, and 48.5 million shares (32.4 million shares
    of Class B Common Stock and 16.1 million shares of Class A Common Stock) had
    been outstanding for all periods presented.
(5) Pro forma earnings per share, as adjusted, assumes that the proceeds from
    the initial offerings were available from January 1, 1994 and were invested
    in short-term investments, and excludes the one-time expense related to the
    employee stock exchange ($2.4 million) and interest expense of $492,000 from
    the 1996 results.
(6) BankAmerica's equity interest represents cumulative historical net income of
    the Company adjusted for net cash transfers to and from BankAmerica. On
    December 3, 1996, BankAmerica exchanged its equity interest in the domestic
    operations of the Company for 30.2 million shares of Class B Common Stock.
    During the second and third quarters of 1997, BankAmerica exchanged its
    equity interest in certain Asian operations of the Company for 2.2 million
    shares of Class B Common Stock.

                     CERTAIN TRANSACTIONS AND RELATIONSHIPS
                      BETWEEN BANKAMERICA AND THE COMPANY
 
GENERAL
 
     The Company was incorporated in October 1996 to combine the domestic
merchant processing businesses of subsidiaries of BAC. BAC's subsidiaries
transferred these merchant processing businesses in December 1996 in exchange
for an aggregate of 30,200,000 shares of Class B Common Stock. In 1997, the
Company acquired the Asian merchant processing businesses of the Bank. On June
2, 1997, the Company acquired the Bank's merchant processing business in
Thailand in consideration for 150,000 shares of Class B Common Stock. On July 1,
1997, the Company acquired the Bank's merchant processing business in the
Philippines in consideration for 550,000 shares of Class B Common Stock. On
September 30, 1997, the Company acquired the Bank's merchant processing business
in Taiwan and merchant processing administrative office in Hong Kong in
consideration for 1,500,000 shares of Class B Common Stock. The consideration
paid and other terms of the transactions pursuant to which the Company acquired
the Bank's merchant processing businesses in Thailand, the Philippines and
Taiwan were approved as to their fairness to the Company by the directors of the
Company who are not affiliated with BAC. On October 31, 1998, the Company closed
its merchant processing operations in Thailand.
 
     BankAmerica holds no shares of Class A Common Stock and 32,400,000 shares
of Class B Common Stock (100% of the outstanding Class B Common Stock),
representing in the aggregate approximately 66.6% of the total number of
outstanding shares of Common Stock. Since shares of Class B Common Stock are
entitled to ten votes per share, and shares of Class A Common Stock are entitled
to one vote per share, BankAmerica controls approximately 95.2% of the combined
voting power of the Common Stock. Such ownership also permits BankAmerica,
either as the holder of Class B Common Stock or in some cases upon the
conversion of such stock into Class A Common Stock, to effect amendments to the
Company's Certificate of Incorporation, a merger, sale of assets, "going
private" or other corporate transactions without the approval of present holders
of Class A Common Stock. Four of the directors of the Company are employees or
former employees of BankAmerica. Three directors of the Company are not
affiliated with BankAmerica or the Company (other than in their capacity as
directors).
 
     The Company has engaged, and continues to engage, in certain transactions
with BankAmerica and its subsidiaries. Management believes that there would not
have been any material change in aggregate historical revenues or expenses of
the Company had the transactions been between unrelated parties or had the
Company been operating other than as a division of a subsidiary of BankAmerica.
 
INTERCOMPANY AGREEMENTS AND ARRANGEMENTS
 
     The Company and the Bank engage in various intercompany transactions and
arrangements, including the provision by the Bank of various services to the
Company. Such services are provided pursuant to certain intercompany agreements
which provide, among other things, for the grant to the Company of a license to
use the Bank name and certain trademarks and servicemarks in connection with the
Company's business. The intercompany agreements also provide for the Bank to
perform for the Company certain product distribution services, processing
services, marketing services, system support services, association and network
sponsorship and representation in the Visa and MasterCard associations,
telecommunications services, tax and treasury services, regulatory, compliance,
accounting and audit services, and other miscellaneous support and
administrative services. The Company and the Bank also have entered into
agreements concerning registration rights, the allocation of tax liabilities and
the leasing of certain facilities by the Company from the Bank. In general, the
intercompany agreements have a term of five years from December 1996 and may be
terminated by the Bank if it beneficially owns shares representing less than a
majority of the voting power of the outstanding common stock of the Company.
 
                                       43
<PAGE>   48
 
     The above-described intercompany agreements and the Non-Competition and
Corporate Opportunities Allocation Agreement (described below) were entered into
at a time when the Company was still wholly owned by the Bank, and therefore
they were not the result of arm's length negotiations between the parties, and
the Company was not represented in connection therewith by separate counsel.
 
     The Bank and the Company have also entered into a Non-Competition and
Corporate Opportunities Allocation Agreement pursuant to which the Bank will not
compete with the Company for a period of five years from December 1996, with
respect to payment processing for merchants to the extent that such payments
arise in the use of credit, charge or debit cards for the purchase of goods and
services and are authorized through an electronic medium originating at the
point of sale in the United States and in Taiwan, Thailand and the Philippines.
 
PAYMENT FOR SERVICES
 
     Fees paid for services provided to the Company or its predecessors by
BankAmerica were approximately $8.2 million, $10.9 million and $7.8 million for
the years ended December 31, 1995, 1996 and 1997, respectively. As part of the
intercompany arrangements, the Company (or its predecessor) paid BankAmerica
total rental expense of $2.2 million, $2.2 million and $2.6 million for the
years ended December 31, 1995, 1996 and 1997, respectively. The Company leases
its facilities from BankAmerica under a five-year lease agreement which can be
canceled with six months notice. In addition, the Company (or its predecessor)
paid BankAmerica $14.7 million, $15.9 million and $3.9 million for the years
ended December 31, 1995, 1996 and 1997, respectively, under tax allocation
arrangements. The Company believes that the cost of services provided under the
intercompany arrangements is not materially different from the costs that would
have been incurred if the Company was unaffiliated with BankAmerica.

                          AGREEMENT AND PLAN OF MERGER
 
     This AGREEMENT AND PLAN OF MERGER (this "Merger Agreement") is made as of
December 22, 1998 among BankAmerica Corporation, a Delaware corporation
("Parent"), BAMS Acquisition Corporation, a Delaware corporation and a wholly
owned subsidiary of Parent ("Acquisition Corp."), and BA Merchant Services,
Inc., a Delaware corporation (the "Company").
 
                                    RECITALS
 
     WHEREAS, on the date of this Merger Agreement, Parent has represented to
the Company that it is directly or indirectly the beneficial owner of 32,400,000
shares of Class B common stock, par value $.01 per share ("Class B Common
Stock"), of the Company (collectively, the "Control Shares");
 
     WHEREAS, the Board of Directors of the Company, based upon the unanimous
recommendation of a special committee of independent directors of the Company
(the "Special Committee"), the Board of Directors of Parent and the Board of
Directors of Acquisition Corp. deem it advisable and in the best interests of
their respective stockholders to consummate, and have unanimously adopted
resolutions approving, the merger of Acquisition Corp. with and into the Company
upon the terms and subject to the conditions set forth herein (the "Merger");
 
     WHEREAS, Parent has adopted this Merger Agreement and approved the Merger
as the sole stockholder of Acquisition Corp.; and
 
     WHEREAS, the Board of Directors of the Company has directed that this
Merger Agreement be submitted to a vote of its stockholders;
 
     NOW, THEREFORE, in consideration of the foregoing and the representations,
warranties, covenants and agreements set forth herein, the parties agree as
follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     SECTION 1.1  The Merger.  Upon the terms and subject to the conditions
hereof, at the Effective Time (as defined in Section 1.2), Acquisition Corp.
shall be merged with and into the Company, with the Company continuing as the
surviving corporation, and the separate existence of Acquisition Corp. shall
cease. Acquisition Corp. and the Company are sometimes referred to as the
"Constituent Corporations" and the Company is sometimes referred to as the
"Surviving Corporation." The Merger shall have the effects set forth in Section
251 of the Delaware General Corporation Law (the "DGCL").
 
     SECTION 1.2  Effective Time of the Merger.  Subject to the provisions of
this Merger Agreement, at the Closing (as defined in Section 1.3) a certificate
of merger (the "Certificate of Merger") shall be duly prepared, executed and
verified by the Company and immediately thereafter delivered to the Secretary of
State of the State of Delaware for filing, as provided in the DGCL, as soon as
practicable on or after the Closing Date (as defined in Section 1.3). The Merger
shall become effective as of the date and time specified in the Certificate of
Merger (such date and time, the "Effective Time").
 
     SECTION 1.3  Closing.  Promptly following the satisfaction or waiver of the
conditions set forth in Article VII hereof and prior to the filing of the
Certificate of Merger, a closing (the "Closing") will take place for the purpose
of confirming the satisfaction or, if permissible, waiver of the conditions set
forth in Article VII hereof, at the offices of Pillsbury Madison & Sutro LLP,
235 Montgomery Street, San Francisco, California 94104, unless another place is
agreed to by the parties. The date and time of the Closing is referred to as the
"Closing Date."
 
                                       I-1
<PAGE>   56
 
     SECTION 1.4  Certificate of Incorporation; Bylaws.
 
     (a) The Certificate of Incorporation of the Surviving Corporation, as in
effect immediately prior to the Effective Time, shall, at the Effective Time, be
amended to read in its entirety as set forth in Exhibit A hereto.
 
     (b) Subject to Section 6.9, the Bylaws of Acquisition Corp., as in effect
immediately prior to the Effective Time, shall be the Bylaws of the Surviving
Corporation without change or amendment until thereafter amended in accordance
with the provisions thereof, the Certificate of Incorporation, Section 6.9 and
applicable laws.
 
     SECTION 1.5  Succession.  At the Effective Time, the separate existence of
Acquisition Corp. shall cease, and the Company shall become entitled to all the
rights, privileges, powers and franchises of a public and private nature, and be
subject to all the obligations, duties, restrictions and disabilities of each of
the Constituent Corporations; and all property, real, personal and mixed, and
all debts due to each of the Constituent Corporations on whatever account, as
well as stock subscriptions and all other things in action belonging to each of
the Constituent Corporations, shall be vested in the Surviving Corporation; and
all and every other interest shall be thereafter as effectually the property of
the Surviving Corporation as they were of the respective Constituent
Corporations; and the title to any real estate vested, by deed or otherwise, in
either of such Constituent Corporations shall not revert or be in any way
impaired by reason of the Merger, but all rights of creditors and all liens upon
any property of Acquisition Corp. shall be preserved unimpaired. To the extent
permitted by law, any claim existing or action or proceedings pending by or
against either of the Constituent Corporations may be prosecuted as if the
Merger had not taken place. All debts, liabilities and duties of the respective
Constituent Corporations shall thenceforth attach to the Surviving Corporation
and may be enforced against it to the same extent as if such debts, liabilities
and duties had been incurred or contracted by it. To the extent permitted by
law, all corporate acts, plans, policies, agreements, arrangements, approvals
and authorizations of Acquisition Corp., its stockholder, Board of Directors and
committees thereof, officers and agents which were valid and effective
immediately prior to the Effective Time, shall be taken for all purposes as the
acts, plans, policies, agreements, arrangements, approvals and authorizations of
the Surviving Corporation and shall be as effective and binding thereon as the
same were with respect to Acquisition Corp. The employees and agents of
Acquisition Corp. shall become the employees and agents of the Surviving
Corporation and continue to be entitled to the same rights and benefits which
they enjoyed as employees and agents of Acquisition Corp.
 
     SECTION 1.6  Directors and Officers of the Surviving Corporation.
 
     (a) The directors of the Company at the Effective Time shall be those
individuals designated by Parent prior to the Closing Date, until their
successors have been duly elected and qualified or until their earlier death,
resignation or removal in accordance with the Surviving Corporation's
Certificate of Incorporation and Bylaws.
 
     (b) The officers of the Company at the Effective Time shall be the officers
of the Surviving Corporation until their successors shall have been duly
appointed and qualified or until their earlier death, resignation or removal in
accordance with the Surviving Corporation's Certificate of Incorporation and
Bylaws.
 
     (c) (i) Parent may at any time change the method of effecting the
transactions contemplated hereby if and to the extent that Parent deems such a
change to be reasonably desirable; provided, however, that no such change shall
(A) alter or change the amount or kind of consideration to be received by the
holders of the Class A Common Stock (as defined in Section 3.2) as provided for
in this Merger Agreement or cause other adverse or potentially adverse
consequences for any such stockholders or any Indemnified Persons (as defined in
Section 6.9) or any holder of Company Options (as defined in Section 2.3)
relative to the consequences provided for in this Merger Agreement; (B) cause a
delay in the consummation of the transactions contemplated by this Merger
Agreement or cause any decrease in the probability that the transactions
contemplated hereby shall be consummated; or (C) take the form of an asset
purchase agreement.
 
     (ii) To facilitate the Merger, the Company will execute such additional
agreements and documents, including any amendment to this Merger Agreement
required in order to effectuate any change provided for in
 
                                       I-2
<PAGE>   57
 
subsection (i) of this Section 1.6(c), and take such other actions as Parent
reasonably determines necessary or appropriate.
 
                                   ARTICLE II
 
           CONVERSION AND EXCHANGE OF SECURITIES; DISSENTERS' SHARES
 
     SECTION 2.1  Conversion of Capital Stock.  At the Effective Time, by virtue
of the Merger and without any action on the part of the holder thereof: (a) each
share of Class A Common Stock issued and outstanding immediately prior to the
Effective Time shall be canceled and be converted into, and become the right to
receive: (i) in the case of such shares other than Dissenting Shares (as defined
in Section 2.4), a cash payment equal to $20.50 (the "Merger Consideration"),
without interest; and (ii) in the case of Dissenting Shares, the consideration
set forth in Section 2.4; (b) all of the Control Shares issued and outstanding
immediately prior to the Effective Time shall in the aggregate be converted
into, and become the right to receive, 100 shares of common stock of the
Surviving Corporation; and (c) each share of capital stock of Acquisition Corp.,
issued and outstanding immediately prior to the Effective Time, shall be
canceled and extinguished and no consideration shall be paid therefor.
 
     SECTION 2.2  Exchange of Certificates.
 
     (a) From and after the Effective Time, ChaseMellon Shareholder Services,
L.L.C. (the "Exchange Agent") shall act as exchange agent in effecting the
exchange of the Merger Consideration for certificates representing shares of
Class A Common Stock entitled to payment pursuant to Section 2.1(a)(i) (the
"Certificates").
 
     (b) Promptly after the Effective Time, the Exchange Agent shall mail to
each record holder of Certificates a letter of transmittal in customary form
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon proper delivery of the Certificates to
the Exchange Agent) and instructions for use in surrendering Certificates and
receiving the Merger Consideration therefor. Upon the surrender of each
Certificate, together with such letter of transmittal duly executed and
completed in accordance with the instructions thereto, the holder of such
Certificate shall be unconditionally entitled to receive in exchange therefor an
amount equal to the Merger Consideration multiplied by the number of shares of
Class A Common Stock formerly represented by such Certificate, and such
Certificate shall be canceled. Until so surrendered, each such Certificate shall
represent solely the right to receive, upon compliance with the conditions set
forth in this subsection 2.2(b), an amount equal to the Merger Consideration
multiplied by the number of shares of Class A Common Stock formerly represented
by such Certificate. No interest shall be paid or accrue on the Merger
Consideration payable upon the surrender of the Certificates. If any Merger
Consideration is to be paid to a person (the "Payee") other than the person in
whose name the Certificate surrendered in exchange therefor is registered (the
"Record Holder"), such Certificate shall be accompanied by all documents
required to evidence and effect the transfer of the rights represented by such
Certificate from the Record Holder to the Payee, and it shall be a condition to
such exchange that the person requesting such exchange shall pay to the Exchange
Agent any transfer or other taxes required by reason of the payment of such
Merger Consideration to the Payee, or that such person shall establish to the
reasonable satisfaction of the Exchange Agent that such tax has been paid or is
not applicable. Notwithstanding the foregoing, to the fullest extent permitted
by law, neither the Exchange Agent nor any party hereto shall be liable to a
holder of shares of Class A Common Stock for any Merger Consideration properly
delivered to a public official pursuant to applicable abandoned property,
escheat and similar laws.
 
     (c) Promptly following the date which is 360 days after the Effective Time,
the Exchange Agent's duties shall terminate, and any funds deposited with the
Exchange Agent that remain unclaimed by holders of Certificates shall be paid to
the Surviving Corporation upon demand. Thereafter, each holder of a Certificate
may surrender such Certificate to the Surviving Corporation along with the
applicable letter of transmittal and (subject to applicable abandoned property,
escheat and similar laws) receive in exchange therefor an amount equal to the
Merger Consideration multiplied by the number of shares of Class A Common Stock
formerly
 
                                       I-3
<PAGE>   58
 
represented by such Certificate, without any interest thereon, but shall have no
greater rights against the Surviving Corporation than may be accorded to general
creditors of the Surviving Corporation.
 
     (d) After the Effective Time, there shall be no transfers on the stock
transfer books of the Surviving Corporation of any shares of Common Stock (as
defined in Section 3.2). If, after the Effective Time, Certificates (other than
Certificates relating to the Control Shares) are presented to the Surviving
Corporation or the Exchange Agent, they shall be canceled and exchanged for the
applicable Merger Consideration, as provided herein, subject to applicable law
in the case of Dissenting Shares.
 
     SECTION 2.3  Options and Restricted Stock.  (a) As soon as practicable
following the date of this Merger Agreement, the Board of Directors of the
Company (or, if appropriate, any committee administering the Company's Long-Term
Incentive Plan and Non-Employee Director Stock Plan (collectively, the "Stock
Plans")) shall adopt such resolutions or take such other actions as are required
to provide for the cancellation of all outstanding options issued under the
Stock Plans ("Company Options") upon the Effective Time, in exchange for a cash
payment of an amount equal to (i) the excess, if any, of (x) the Merger
Consideration per share over (y) the exercise price per share of such Company
Option, multiplied by (ii) the number of shares of Class A Common Stock subject
to such Company Option for which such Company Option shall not theretofore have
been exercised, whether or not then vested and exercisable. Prior to the
Effective Time, the Company shall use its commercially reasonable efforts to (A)
obtain any consents from holders of Company Options, and (B) make any amendments
to the terms of such options that are necessary to give effect to the
transactions contemplated by this Section 2.3(a); provided, however, that the
failure by the Company to obtain any such consents specified in the preceding
clause (A) or to make any amendments specified in the preceding clause (B) or
the failure of the Company's Board of Directors to take any action referred to
in this Section 2.3 shall not give rise to a right of termination by Parent or
Acquisition Corp. under any provision of this Merger Agreement or result in the
failure of the condition set forth in Section 7.2(a) or any other condition to
Parent's or Acquisition Corp.'s obligation to consummate the transactions
contemplated by this Merger Agreement. Notwithstanding any other provision of
this Section 2.3(a), payment may be withheld in respect of any Company Option
until necessary consents are obtained.
 
     (b) Each outstanding share of unvested restricted Class A Common Stock
issued pursuant to a Stock Plan (each, a "Restricted Share") shall, immediately
prior to the Effective Time, be canceled and be converted into, and become the
right to receive, the Merger Consideration in accordance with Section 2.1.
Notwithstanding the foregoing, the amount otherwise payable to certain senior
executive officers of the Company pursuant to this Section 2.3(b) shall be
distributed to such officers on a deferred basis, payable to each such executive
officer in accordance with such officer's originally scheduled release dates for
the Restricted Shares and otherwise, including as to acceleration of vesting
events, in accordance with the provisions of the BankAmerica Corporation
Restricted Stock Retention Grant Program. Pending such distribution, such
deferred amounts shall bear an agreed rate of return.
 
     (c) All amounts payable pursuant to this Section 2.3 shall be subject to
any required withholding of taxes and, except as provided in Section 2.3(b),
shall be paid without interest.
 
     (d) The Board of Directors of the Company (or, if appropriate, any
committee administering the Stock Plans) shall adopt such resolutions or take
such actions as are required to terminate the Stock Plans as of the Effective
Time, to delete as of the Effective Time the provision in any other benefit plan
of the Company providing for the issuance, transfer or grant of any capital
stock of the Company or any interest in respect of any capital stock of the
Company and to ensure that following the Effective Time no holder of a Company
Option or any participant in any Stock Plan or other Company benefit plan shall
have any right thereunder to acquire any capital stock of the Company or the
Surviving Corporation.
 
     SECTION 2.4  Dissenters' Rights.  Notwithstanding anything in this Merger
Agreement to the contrary, shares of Class A Common Stock which are issued and
outstanding immediately prior to the Effective Time and which are held by
stockholders that have not voted such shares in favor of the Merger and have
delivered a written demand for the appraisal of such shares in the manner
provided in the DGCL (such shares, the "Dissenting Shares") shall not be
converted into or represent the right to receive the Merger Consideration and
the holders thereof shall only be entitled to such rights as are granted by
Section 262 of the
                                       I-4
<PAGE>   59
 
DGCL. Each holder of Dissenting Shares that becomes entitled to payment for such
shares pursuant to Section 262 of the DGCL shall receive payment therefor from
the Surviving Corporation in accordance with the DGCL; provided, however, that
(i) if any such holder of Dissenting Shares shall have failed to establish that
such holder is entitled to appraisal rights as provided in Section 262 of the
DGCL, or (ii) if any such holder of Dissenting Shares shall have effectively
withdrawn the demand for appraisal of such shares or lost the right to appraisal
and payment of such shares under Section 262 of the DGCL, or (iii) if neither
the Surviving Corporation nor such holder of Dissenting Shares shall have filed
a petition demanding a determination of the value of all Dissenting Shares
within the time provided in Section 262 of the DGCL, such holder's or holders'
(as the case may be) shares of Class A Common Stock shall thereupon be deemed to
have been converted, as of the Effective Time, into and represent the right to
receive from the Surviving Corporation the Merger Consideration, without
interest thereon, as provided in Section 2.1 hereof.
 
                                  ARTICLE III
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     The Company represents and warrants to each of Parent and Acquisition Corp.
as follows:
 
     SECTION 3.1  Organization.  The Company is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware
and has all requisite corporate power and corporate authority and all necessary
governmental approvals to own, lease and operate its properties and to carry on
its business as now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power, authority and
governmental approvals would not have a Company Material Adverse Effect (as
defined in Section 9.9). The Company is duly qualified or licensed to do
business and in good standing in each jurisdiction in which the property owned,
leased or operated by it or the nature of business conducted by it makes such
qualification or licensing necessary, except where the failure to be so duly
qualified or licensed and in good standing individually or in the aggregate
would not have a Company Material Adverse Effect.
 
     SECTION 3.2  Capitalization.  As of the date hereof, the authorized capital
stock of the Company consists of: (i) 200,000,000 shares of Class A common
stock, par value $.01 per share ("Class A Common Stock" and, collectively with
the Class B Common Stock, the "Common Stock"), of which, as of the date hereof,
16,267,110 shares were issued and outstanding and no shares were held in
treasury; (ii) 50,000,000 shares of Class B Common Stock, of which, as of the
date hereof, 32,400,000 shares were issued and outstanding and no shares were
held in treasury; and (iii) 10,000,000 shares of preferred stock, par value $.01
per share, of which no shares are issued and outstanding and no shares are held
in treasury. As of the date hereof, 1,608,454 shares of Class A Common Stock
were reserved for issuance upon exercise of outstanding Company Options and
payments of other outstanding awards pursuant to the Stock Plans. All the
outstanding shares of the Company's capital stock are, and all shares which may
be issued pursuant to the exercise of Company Options or other outstanding
awards or the conversion of outstanding shares of Class B Common Stock will be,
when issued in accordance with the respective terms thereof, duly authorized,
validly issued, fully paid and nonassessable and free of any preemptive rights.
Except as set forth above and except for shares of Class A Common Stock issued
upon the exercise of Company Options, and except pursuant to the provisions of
this Merger Agreement, as of the date hereof there is no (i) share of capital
stock of the Company issued and outstanding or (ii) option, warrant, call,
subscription or other right, agreement or commitment of any character (a)
relating to the issued or unissued capital stock of the Company to which the
Company is a party (other than the Company Options) (b) obligating the Company
to issue, transfer or sell or cause to be issued, transferred or sold any share
of capital stock of, or other equity interest in, the Company or securities
convertible into or exchangeable for such shares or equity interests or
obligating the Company to grant, extend or enter into any such option, warrant,
call, subscription or other right, agreement or commitment. There is no
outstanding obligation of the Company to repurchase, redeem or otherwise acquire
any shares of capital stock of the Company. Except pursuant to this Merger
Agreement, there is no voting trust or other agreement or understanding to which
the Company is a party or by which it is bound with respect to the voting of the
capital stock of the Company. Except for that certain Registration Rights
 
                                       I-5
<PAGE>   60
 
Agreement, dated as of December 3, 1996 among the Company, the Bank and Bank of
America N.W., National Association, there are no agreements obligating the
Company to register any of its shares of capital stock under the Securities Act.
 
     SECTION 3.3  Authority.  The Company has the requisite corporate power and
corporate authority to execute and deliver this Merger Agreement and to carry
out its obligations hereunder. The execution, delivery and performance by the
Company of this Merger Agreement and the consummation by the Company of the
Merger and of the other transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of the Company, and no
other corporate proceedings on the part of the Company are necessary to
authorize this Merger Agreement or to consummate the transactions contemplated
hereby (other than with respect to the Merger, the approval and adoption of the
Merger Agreement by the stockholders of the Company in accordance with the DGCL
and the Company's Certificate of Incorporation). This Merger Agreement has been
duly executed and delivered by the Company and constitutes a valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms.
 
     SECTION 3.4  Consents and Approvals.  Except for filings, permits,
authorizations, consents and approvals as may be required under, and other
applicable requirements of, the Securities Act of 1933 (the "Securities Act"),
the Securities Exchange Act of 1934 (the "Exchange Act") and state securities or
blue sky laws, and the delivery of the Certificate of Merger to the Secretary of
State of the State of Delaware for filing as required by the DGCL, no filing
with or notice to, and no permit, authorization, consent or approval of, any
United States federal or state court or tribunal or United States
administrative, governmental or regulatory body, agency or authority (each, a
"Governmental Entity") is required to be made or obtained by the Company on or
before the Closing Date for the execution and delivery by the Company of this
Merger Agreement or for the consummation by the Company of the Merger, except
where the failure to obtain such permits, authorizations, consents or approvals
or to make such filings or give such notice would not have a Company Material
Adverse Effect.
 
     SECTION 3.5  Information.  None of the information supplied by the Company
specifically for inclusion or incorporation by reference in (i) the Proxy
Statement (as defined in Section 6.1) and (ii) any other document (the "Other
Filings") to be filed with the Securities and Exchange Commission (the "SEC") or
any regulatory agency by Parent, Acquisition Corp. or the Company in connection
with the transactions contemplated by this Merger Agreement, at the respective
times filed with the SEC or such other regulatory agency and, in addition, in
the case of the Proxy Statement, at the date it or any amendment or supplement
is mailed to stockholders and at the time of the Stockholders' Meeting (as
defined in Section 6.3), will contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading. The Proxy Statement will comply in all material
respects with the provisions of the Exchange Act and the rules and regulations
thereunder, except that no representation or warranty is made by the Company
with respect to statements made therein based on information supplied by Parent
or Acquisition Corp. specifically for inclusion or incorporation by reference in
the Proxy Statement.
 
     SECTION 3.6  Opinion of Financial Advisor.  The Special Committee and the
Board of Directors of the Company (at meetings duly called and held) each have
determined as of the date hereof that the Merger is fair to and in the best
interests of the holders (other than Parent and its Affiliates (as defined in
Section 9.9)) of Class A Common Stock. The Special Committee has received the
opinion, dated the date hereof, of Credit Suisse First Boston Corporation (the
"Financial Advisor"), the Special Committee's financial advisor, substantially
to the effect that the consideration to be received in the Merger by the holders

any notification or communication from any agency or department of any United
States federal, state or local government, including, without limitation, the

Material Adverse Effect, (ii) threatening to revoke any license, franchise,
permit or governmental authorization which is material to the Company, (iii)
requiring or threatening to require the Company to, or indicating that the
Company may be required to, enter into a cease and desist order, agreement or
memorandum of understanding or any other agreement restricting or limiting or
purporting to restrict or limit in any manner the operations of the Company,
unless such restriction or limitation other than with respect to a cease and
desist order would not have a Company Material Adverse Effect, or (iv)
directing, restricting or limiting, or purporting to direct, restrict or limit,
in any material respect the operations of the Company (any such notice,
communication, memorandum, agreement or order described in this sentence herein
referred to as a "Regulatory Agreement").

Agreement.

terms of the Stock Plans. Since December 10, 1998, the Company has not granted
any awards of stock options or awards of shares of restricted Class A Common
Stock under the Stock Plans.

as a whole. Each of Parent and Acquisition Corp. is duly qualified or licensed

DGCL, no filing with or notice to, and no permit, authorization, consent or
approval of, any Governmental Entity is required to be made or obtained by
Parent or any Affiliate (other than the Company) on or before the Closing Date
for the execution and delivery by Parent and Acquisition Corp. of this Merger
Agreement or for the consummation by Parent and Acquisition Corp. of the Merger,
except where the failure to obtain such permits, authorizations, consents or

adverse effect on Parent and its Subsidiaries taken as a whole.
 
     SECTION 4.4  Information.  None of the information supplied by Parent or
Acquisition Corp. specifically for inclusion or incorporation by reference in
the Proxy Statement and the Other Filings, at the respective times filed with
the SEC or such other regulatory agency and, in addition, in the case of the

hereby and has not engaged in any business activities or conducted any
operations other than in connection with the transactions contemplated hereby.

(other than the Company).
 
     SECTION 4.7  Class B Common Stock.  Parent is directly or indirectly the
beneficial owner of, and has (and as of the record date for persons entitled to

     Company.
 
          (c) The Company will not issue, deliver or sell, or authorize or
     propose the issuance, delivery or sale of, any shares of its capital

     ordinary course of business) acquire or agree to acquire any assets,
     in each case that are material individually or in the aggregate to the
     Company.
 
          (e) The Company will not sell, lease, license, encumber or
     otherwise dispose of, or agree to sell, lease, license, encumber or
     otherwise dispose of, any of its assets that are material individually
     or in the aggregate to the Company, other than in the ordinary course

     more of its directors, officers, employees or independent contractors
     or (y) except for normal increases in the ordinary course of business
     consistent with past practice that in the aggregate do not result in a

                                       I-9
<PAGE>   64
 
     Company, increase in any manner the compensation or benefits
     (including severance benefits) of any director, officer, employee or
     independent contractor or pay any benefit not required by any plan and
     arrangement as in effect at the date hereof (including the granting of

          (i) The Company will not take any action that would, or would be

                             ADDITIONAL AGREEMENTS
 
     SECTION 6.1  Preparation of the Proxy Statement and Schedule 13E-3.  The
parties will promptly prepare and file with the SEC a proxy statement in
connection with the vote of the Company's stockholders with respect to the
Merger (the "Proxy Statement") and a Transaction Statement on Schedule 13E-3
(the "Schedule 13E-3") as required under the Exchange Act in connection with the
Merger. Each of the Company and Parent will furnish all information concerning
itself and its Affiliates that is required to be included in the Proxy Statement
and the Schedule 13E-3 for inclusion in the Proxy Statement and the Schedule
13E-3.
 
     SECTION 6.2  Access to Information.  During the period prior to the first
to occur of the Effective Time or the termination of this Merger Agreement, (i)
upon reasonable notice, the Company will afford to the officers, employees,
accountants, counsel and other representatives of Parent, reasonable access,
during normal business hours, to all its properties, books, contracts,
commitments and records, and (ii) the Company will furnish promptly to Parent
(a) a copy of each report, schedule, registration statement and other document
filed or received by it during such period pursuant to the requirements of the
Federal securities laws and (b) all other information concerning its business,
properties and personnel as Parent reasonably may request; provided, however,
that the Company shall not be required to permit any access, or to furnish any
information, that in the reasonable judgment of the Special Committee, after
consultation with counsel to the Special Committee, would jeopardize protections
afforded the Company or the Special Committee under the attorney-client
privilege or the attorney work product doctrine.
 
     SECTION 6.3  Stockholders' Meeting.  The Company will call a meeting of its
stockholders (the "Stockholders' Meeting") to be held as promptly as practicable
for the purpose of voting upon the Merger Agreement and shall submit the Merger
Agreement to its stockholders for a vote at such Stockholders'
 
                                      I-10
<PAGE>   65
 
Meeting. The Company shall not, without the prior written consent of Parent
(which consent shall not be unreasonably withheld), postpone or adjourn the
Stockholders' Meeting unless this Merger Agreement shall be terminated prior to
the date thereof. The Company, through its Board of Directors, subject to the
fiduciary duties of the Board of Directors of the Company or the Special
Committee after consultation with counsel, will recommend approval of the Merger
Agreement to the Company's stockholders; provided, however, that at any time at
or prior to the Stockholders' Meeting either the Special Committee or the Board
of Directors of the Company (or both the Board of Directors and the Special
Committee) may revoke, modify or qualify its recommendation with respect to the
Merger Agreement if the Board of Directors of the Company or the Special
Committee determines in good faith (after consultation with legal counsel) that
failure to revoke, modify or qualify such recommendation would create a material
risk of liability for breach of its fiduciary duties. At the Stockholders'
Meeting (and at any adjournment or postponement thereof), Parent will vote or
cause to be voted in favor of approval and adoption of the Merger Agreement and
approval of the Merger all of the outstanding shares of Class B Common Stock;
provided, however, that if such recommendation of the Special Committee is
revoked, modified or qualified in a manner adverse to Parent, Parent may, but
shall not be obligated to, cause such shares to be so voted.
 
     SECTION 6.4  Legal Requirements to Merger.  Each of the Company, Parent and
Acquisition Corp. will take, or cause to be taken, all reasonable actions
necessary to comply promptly with all legal requirements that may be imposed on
it with respect to the Merger and will cooperate with and furnish information to
each other in connection with any such requirements imposed upon any of them or
any of their Subsidiaries in connection with the Merger. Each of the Company,
Parent and Acquisition Corp. will, and will cause any of its Subsidiaries to,
take all reasonable actions necessary to obtain (and will cooperate with each
other in obtaining) any consent, authorization, order or approval of, or any
exemption by, any Governmental Entity required to be obtained or made by Parent,
Acquisition Corp., or any Affiliate thereof, or the Company in connection with
the Merger.
 
     SECTION 6.5  Additional Agreements; Commercially Reasonable
Efforts.  Subject to the terms and conditions of this Merger Agreement, each of
the parties will use its commercially reasonable efforts to take, or cause to be
taken, all action and to do, or cause to be done, all things necessary, proper
or advisable under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Merger Agreement, subject to the
appropriate vote of stockholders of the Company described in Section 6.3,
including cooperating (to the extent reasonable) with the other parties and
providing all relevant information. If after the Effective Time any further
action is necessary or desirable to carry out the purposes of this Merger
Agreement or to vest the Surviving Corporation with full title to all
properties, assets, rights, approvals, immunities and franchises of either of
the Constituent Corporations, the proper officers and directors of each party
will take all such necessary action.
 
     SECTION 6.6  Expenses.  Whether or not the Merger is consummated, but
subject to Section 6.10, all costs and expenses incurred in connection with this
Merger Agreement and solely and directly related to the transactions
contemplated hereby will be paid by the party that incurred such costs and
expenses; provided, however, that the printing and mailing costs associated with
the Proxy Statement and the Schedule 13E-3 will be paid by Parent; provided
further, however, that costs and expenses incurred by or on behalf of an
individual stockholder (or a group of stockholders) shall not be treated as
solely and directly related to the transactions contemplated hereby; provided
further, that if this Merger Agreement shall have been terminated pursuant to
Section 8.1 as a result of the willful breach by a party of any of its
representations, warranties, covenants or agreements set forth in this Merger
Agreement, such breaching party will pay the costs and expenses incurred by the
other parties in connection with this Merger Agreement.
 
     SECTION 6.7  Acquisition Proposals.  The Company shall not, and shall use
its reasonable best efforts to cause its officers, directors and employees and
any investment banker, attorney, accountant or other agent retained by it not to
(i) initiate, knowingly encourage or solicit, directly or indirectly, the making
of any proposal or offer (an "Acquisition Proposal") to acquire all or any
significant part of the business and properties or capital stock of the Company,
whether by merger, purchase of securities or assets, tender offer or otherwise
(an "Acquisition Transaction"), or initiate, directly or indirectly, any contact
with any person in an effort to or with a view towards soliciting any
Acquisition Proposal or (ii) participate in any discussion or
                                      I-11
<PAGE>   66
 
negotiations regarding, or furnish to any other person any information with
respect to, an Acquisition Proposal. Notwithstanding the foregoing, the Company
may (x) furnish or cause to be furnished information subject to a
confidentiality agreement in a form substantially similar to that previously
executed by Parent and (y) in response to an Acquisition Proposal, issue a
communication to its security holders of the type contemplated by Rule 14d-9(e)
or 14e-2 under the Exchange Act or otherwise communicate the Board of Director's
position with respect to such Acquisition Proposal to the stockholders of the
Company. In the event that the Company receives an Acquisition Proposal, it
shall promptly inform Parent as to the material terms thereof.
 
     SECTION 6.8  Public Statements.  The parties will consult with each other
prior to issuing any public announcement with respect to this Merger Agreement
or the transactions contemplated hereby and will not issue any such public
announcement prior to such consultation, except that any party may issue such a
public announcement prior to such consultation if and to the extent required by
law or any listing agreement with a national securities exchange, in which case
such party will use its commercially reasonable efforts to consult with the
other parties prior to issuing such public announcement.
 
     SECTION 6.9  Indemnification and Insurance.
 
          (a) For a period of six years from the Effective Time, the
     Surviving Corporation will maintain all rights to indemnification
     (including with respect to the advancement of expenses incurred in the
     defense of any action or suit) existing on the date of this Merger
     Agreement in favor of the current and former directors and executive
     officers of the Company (each such current or former director or
     executive officer being referred to in this Merger Agreement as an
     "Indemnified Person") as provided in the Company's Certificate of
     Incorporation and Bylaws or otherwise, in each case in effect on the
     date of this Merger Agreement and (ii) the Surviving Corporation will
     not take any action to: (i) amend the Certificate of Incorporation or
     Bylaws of the Surviving Corporation to reduce or limit the rights of
     indemnity afforded to any Indemnified Person; (ii) restrict the
     ability of the Surviving Corporation to indemnify any Indemnified
     Person; or (iii) hinder, delay or make more difficult the exercise of
     such rights of indemnity or the ability to indemnify.
 
          (b) For a period of six years from the Effective Time, the
     Surviving Corporation will indemnify to the fullest extent possible
     under its Certificate of Incorporation, its Bylaws and applicable law
     each Indemnified Person against all losses, damages, liabilities or
     claims made against such Indemnified Person arising from such
     Indemnified Person's service in such capacity prior to and including
     the Effective Time, which indemnity shall be not less favorable in any
     respect than that currently available pursuant to the Company's
     Certificate of Incorporation and Bylaws.
 
          (c) Should any claim or claims be made against any Indemnified
     Person, arising from his or her services as such, the provisions of
     this Section 6.9 respecting the Certificate of Incorporation and
     Bylaws will continue in effect until the final disposition of all such
     claims.
 
          (d) Without limiting the provisions of paragraphs (a) through (c)
     or (e) through (g) of this Section 6.9, for a period of six years from
     the Effective Time, Parent shall, to the extent permitted by
     applicable law, indemnify and hold harmless each Indemnified Person
     against and from any costs, fees and expenses (including reasonable
     attorneys' fees), judgments, fines, losses, claims, damages,
     liabilities and amounts paid in settlement in connection with any
     lawsuit, court action or other court proceeding, claim, or
     investigation, whether civil, criminal, administrative or
     investigative (each, a "Legal Proceeding"), to the extent such Legal
     Proceeding arises out of or pertains to (1) any action or omission or
     alleged action or omission in his or her capacity as a director or
     executive officer, or as employee or agent, of the Company (regardless
     of whether such action or omission, or alleged action or omission,
     occurred prior to the Effective Time) or (2) any of the transactions
     contemplated by this Merger Agreement; provided, however, that if, at
     any time prior to the sixth anniversary of the Effective Time, any
     Indemnified Person delivers to Parent a written notice asserting a
     claim for indemnification under this Section 6.9(d), then the claim
     asserted in such notice shall survive the sixth anniversary of the
     Effective Time until such time as such claim
                                      I-12
<PAGE>   67
 
     is fully and finally resolved; provided further, however, that the
     obligations of Parent to advance any costs incurred in connection with
     a Legal Proceeding in advance of any disposition of such Legal
     Proceeding shall be required to be made only upon delivery to Parent
     by the Indemnified Person of an undertaking to repay all amounts so
     advanced if it shall ultimately be determined that such Indemnified
     Person is not entitled to indemnification hereunder. Notwithstanding
     anything to the contrary contained in this Merger Agreement, Parent
     agrees that it will not settle or compromise or consent to the entry
     of any judgment or otherwise seek termination with respect to any
     Legal Proceeding for which indemnification may be sought under this
     Merger Agreement unless such settlement, compromise, consent or
     termination includes an unconditional release of all Indemnified
     Persons from all liability arising out of such Legal Proceeding. The
     amount of any cost, fee, expense, judgment, fine, loss, claim,
     liability and amount paid in settlement for which indemnification is
     provided under this Section 6.9(d) shall be net of any amounts
     recovered or recoverable therefor by any Indemnified Party under any
     applicable insurance policies or otherwise.
 
          (e) For a period of six years from the Effective Time, the
     Surviving Corporation (or Parent on its behalf) will cause to be
     maintained in effect, at no expense to the beneficiaries thereof,
     directors' and officers' liability insurance providing at least the
     same coverage with respect to the Company's officers and directors as
     the policies, if any, maintained from time to time by or on behalf of
     Parent with respect to its officers and directors (or, if broader in
     scope, the policies maintained by the Company as of the date of this
     Merger Agreement); provided, however, that (i) the aggregate annual
     premium payable therefor shall not exceed 150% of the aggregate annual
     premium payable for such directors' and officers' liability insurance
     policies as are currently in effect, and (ii) if the aggregate annual
     premium of such insurance coverage exceeds the amount referred to in
     clause (i) of this sentence, Parent shall be obligated to obtain a
     policy with the broadest coverage available for a cost not exceeding
     such amount. In the event any claim is made against the current or
     former directors or officers of the Company that is covered or
     potentially covered by, insurance, the Surviving Corporation and
     Parent will do nothing that would forfeit, jeopardize, restrict or
     limit the insurance coverage available for that claim until the final
     disposition of that claim.
 
          (f) If the Surviving Corporation or any of its successors or
     assigns or Parent or any of its successors and assigns (i)
     consolidates with or merges into any other person and shall not be the
     continuing or surviving corporation or entity of such consolidation or
     merger or (ii) transfers all or substantially all of its properties
     and assets to any person, proper provision shall be made so that the
     successors and assigns of the Surviving Corporation or Parent, as the
     case may be, shall assume the obligations of the Surviving Corporation
     set forth in this Section 6.9.
 
          (g) The provisions of this Section 6.9 are intended to be for the
     benefit of, and shall be enforceable by, each Indemnified Person and
     his or her heirs and representatives.
 
     SECTION 6.10  Taiwan Business.  It is agreed that the assets and business
of the Company located in the Republic of China (the "Taiwan Business") may, at
the election of Parent, be included within certain assets and businesses of
Parent or its Affiliates which may be the subject of divestitures by Parent or
its Affiliates after the date of this Merger Agreement. Parent agrees to consult
with the Company in connection with such divestitures. It is further agreed that
the Company shall be entitled to receive its allocable proportion of the
consideration received by Parent and its Affiliates for such Asian assets and
businesses, of which the Taiwan Business shall be a part, such allocation to be
determined in good faith by Parent. In the event that this Merger Agreement
shall be terminated for any reason and prior to or thereafter the divestiture of
the Taiwan Business shall be consummated on terms which result in the
consideration therefor receivable hereunder by the Company being less than the
market value of the securities of the Company issued in connection with the
acquisition thereof, determined in the manner consistent with the valuation used
at the time of such acquisitions, Parent shall promptly pay to the Company the
difference between such market value and the consideration therefor receivable.

     certificate signed on behalf of the Company by the chief executive
     officer or an executive vice president of the Company to the foregoing

     of an earlier date) as of the Closing Date as though made on and as of
     the Closing Date, except as otherwise contemplated by this Merger
     Agreement; provided, however, that for purposes of determining under
     this Section 7.3(a) whether such representations and warranties are

     following written notice from the Company to Parent of such breach and
     (y) the Outside Date; provided, however, that the Company shall not be

          (e) by either Parent, Acquisition Corp. or the Company if the
     Merger shall not have been consummated before April 30, 1999 (the
     "Outside Date"); provided, however, that the right to terminate this
     Merger Agreement under this Section 8.1(e) will not be available to
     any party whose breach of its representations and warranties in this
     Merger Agreement or whose failure to perform any of its covenants and
     agreements under this Merger Agreement has been the cause of or
     resulted in the failure of the Merger to occur on or before such date;

Company or their respective officers, directors or stockholders, except to the
extent that such termination
 
                                      I-15
<PAGE>   70

its representations, warranties, covenants or agreements set forth herein.
 
     SECTION 8.3  Amendment; Extension; Waiver.
 
     (a) This Merger Agreement may be amended by the parties, by action taken or
authorized by their respective Boards of Directors, at any time before or after
approval and adoption of the Merger Agreement by the stockholders of the
Company. After any such approval, however, no amendment shall be made that by
law requires further approval by such stockholders without such further
approval. This Merger Agreement may not be amended except by an instrument in

     (b) At any time prior to the Effective Time the parties, to the extent
legally allowed, (i) may extend the time for the performance of any obligation
of the other parties, (ii) may waive any inaccuracy in the representations and
warranties contained in this Merger Agreement or in any document delivered

                                 MISCELLANEOUS

Nominees.  Notwithstanding anything to the contrary contained in this Merger
Agreement, for purposes of this Merger Agreement (including, without limitation,
Sections 7.2(a) and 8.1(b)):
 
     (a) no representation or warranty of the Company contained in this Merger
Agreement shall be deemed to be untrue, incorrect or breached if (A) the failure
of the representation or warranty to be true or correct, or the breach of the
representation or warranty, results from any act or omission of (1) Parent, (2)
any person or persons acting at the request or direction of Parent, or (3) any
one or more officer(s), director(s), employee(s) or representative(s) of Parent
or its Affiliates (including, without limitation, any one or more member(s) of
the Board of Directors of the Company other than the members of the Special
Committee) (each such officer, director, employee and representative referred to
in this clause (3) being referred to in this Merger Agreement as a "Parent
Nominee"); or (B) any facts or circumstances that constitute or give rise to the
untruth or inaccuracy in (or breach of) the representation or warranty were
known to Parent or any Parent Nominee at the time such representation or
warranty was made by the Company, and
 
     (b) the Company shall not be deemed to have breached any of its covenants
or agreements contained in this Merger Agreement if (A) the breach of the
covenant or agreement results from any act or omission of (1) Parent, (2) any
person or persons acting at the request or direction of Parent, or (3) any one
or more Parent Nominee(s); or (B) any facts or circumstances that constitute or
give rise to such breach were known to Parent or any Parent Nominee at the time
of or prior to the occurrence of such breach and if, after Parent shall have
become aware of such facts and circumstances, Parent shall have failed promptly
to advise the Special Committee in writing of such facts or circumstances.
 
For purposes of this Section 9.1, Parent shall be deemed to have knowledge of a
fact or circumstance or act or omission if such fact or circumstance or act or
omission was formally considered at a meeting of the Board of Directors of the
Company at which any Parent Nominee was present throughout such consideration or
included in any written materials provided to any such Parent Nominee.
 
     SECTION 9.2  Approval by Special Committee.  To the extent permitted by
applicable law, (1) the approval of a majority of the members of the Special
Committee shall be required to authorize each of the following actions (and none
of such actions shall be valid unless approved by a majority of the members of
the Special Committee): (i) any termination of this Merger Agreement by the
Company, (ii) any agreement by

<PAGE>   71
 
the Company to amend this Merger Agreement, (iii) any extension of time for the
performance of any of the obligations or other acts of Parent or Acquisition
Corp., and (iv) any waiver of compliance with or any waiver of any breach of any
of the representations, warranties, covenants or conditions contained in this
Merger Agreement for the benefit of the Company; and (2) the authorization of
any such action by a majority of the Special Committee shall constitute the
authorization of such action by the Board of Directors of the Company, and no
other action on the part of the Company or any other director of the Company
shall be required to authorize such action.
 
     SECTION 9.3  Nonsurvival of Representations, Warranties and
Agreements.  None of the representations, warranties, covenants and agreements
in this Merger Agreement (or the exhibits and schedules hereto) or in any
instrument delivered pursuant to this Merger Agreement shall survive the

     there has been, a "Company Material Adverse Effect"; (ii) any adverse

     industry generally shall not be deemed to constitute, and shall not be
     taken into account in determining whether there has been, a "Company

                                OPINION OF CSFB
 
December 21, 1998
 
Special Committee of the Board of Directors
BA Merchant Services, Inc.
One South Van Ness Avenue
San Francisco, CA 94103
 
Dear Sirs:
 
You have asked us to advise you with respect to the fairness to the stockholders
of BA Merchant Services, Inc. (the "Company"), other than BankAmerica
Corporation and its affiliates ("BankAmerica"), from a financial point of view
of the Consideration (as defined below) to be received by such stockholders
pursuant to the terms of the Agreement and Plan of Merger, dated as of December
21, 1998 (the "Merger Agreement"), among the Company, BankAmerica and BAMS
Acquisitions Corporation (the "Merger Sub"). The Merger Agreement provides for,
among other things, the merger (the "Merger") of Merger Sub with and into the
Company pursuant to which the Company will become a wholly-owned subsidiary of
BankAmerica and each outstanding share of Class A common stock, par value $.01
per share (the "Class A Common Stock"), of the Company, other than such shares
of Class A Common Stock owned by BankAmerica, will be converted into the right
to receive $20.50 in cash (the "Consideration"). It is our understanding that,
as of the date hereof, BankAmerica owns 100% of the outstanding shares of the
Class B common stock, par value $0.01 per share (the "Class B Common Stock", and
together with the Class A Common Stock, the "Common Stock"), which represents
95.2% of the voting power of the Common Stock.
 
In arriving at this opinion, we have reviewed certain publicly available
business and financial information relating to the Company, including, but not
limited to, the terms and conditions of the existing contractual relationship
between the Company and BankAmerica, as well as the Merger Agreement. We have
also reviewed certain other information, including financial forecasts, provided
to us by the Company and have met with the Company's management to discuss the
business and prospects of the Company.
 
We have also considered certain financial and stock market data of the Company,
and we have compared that data with similar data for other publicly-held
companies in businesses similar to those of the Company and we have considered
the financial terms, to the extent publicly available, of certain other business
combinations and other transactions which have recently been effected. We have
considered that BankAmerica's ownership of 100% of the outstanding shares of the
Class B Common Stock represents 95.2% of the voting power of the Common Stock.
We also considered such other information, financial studies, analyses and
investigations and financial, economic and market criteria which we deemed
relevant.
 
In connection with our review, we have not assumed any responsibility for
independent verification of any of the foregoing information and have relied on
its being complete and accurate in all material respects. With respect to the
financial forecasts, we have assumed with your permission that they have been
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the Company's management as to the future financial performance
of the Company. In addition, we have not made an independent evaluation or
appraisal of the assets or liabilities (contingent or otherwise) of the Company,
nor have we been furnished with any such evaluations or appraisals. Our opinion
is necessarily based upon
 
                                      II-1
<PAGE>   77
Special Committee of the Board of Directors

financial, economic, market and other conditions as they exist and can be
evaluated on the date hereof. We were not requested to, and at your direction
did not, solicit third party indications of interest in acquiring all or any
part of the Company.
 
We have acted as financial advisor to the Special Committee in connection with
the Merger and will receive a fee for our services, a significant portion of
which is contingent upon the rendering of this opinion. In the past, we have
performed certain investment banking and financial advisory services for
NationsBank Corporation, the predecessor to BankAmerica ("NationsBank"), and
BankAmerica Corporation, a corporation merged with and into NationsBank, and may
continue to do so, and have received, and may receive, fees for the rendering of
such services. In addition, in the ordinary course of our business, Credit
Suisse First Boston and its affiliates may actively trade the debt and equity
securities of both the Company and BankAmerica for their own account and for the
accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.
 
It is understood that this letter is for the information of the Special
Committee in connection with its consideration of the Merger, does not
constitute a recommendation to any stockholder as to how such stockholder should
vote on the proposed Merger and is not to be quoted or referred to, in whole or
in part, in any registration statement, prospectus or proxy statement, or in any
other document used in connection with the offering or sale of securities, nor
shall this letter be used for any other purposes, without Credit Suisse First
Boston's prior written consent.
 
Based upon and subject to the foregoing, it is our opinion that, as of the date
hereof, the Consideration to be received by the holders of the Class A Common
Stock, other than BankAmerica, in the Merger is fair to such stockholders from a
financial point of view.
 
Very truly yours,
 
CREDIT SUISSE FIRST BOSTON CORPORATION

                                   ANNEX III
 
                            SECTION 262 OF THE DGCL
 
Section 262. Appraisal Rights.
 
     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 264 of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;
 
             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;
 
             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or
 
             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
 
                                      III-1
<PAGE>   79
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or
 
          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.
 
                                      III-2
<PAGE>   80
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
                                      III-3
<PAGE>   81
 
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
