                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--ORGANIZATION AND NATURE OF OPERATIONS
 
  BA Merchant Services, Inc. ("BAMS" or the "Company") was incorporated on
October 11, 1996 and commenced operations December 4, 1996, upon the transfer
by Bank of America National Trust & Savings Association (the "Bank") and Bank
of America NW, National Association ("BANW", formerly Seattle-First National
Bank) of their respective United States merchant processing businesses to BAMS
in consideration for 30.2 million shares of Class B Common Stock (the
"Reorganization"). Effective January 1, 1997, BANW was merged into the Bank.
The Bank is a wholly owned subsidiary of BankAmerica Corporation ("BAC").
References in the consolidated financial statements and these Notes to
Consolidated Financial Statements to "BAC" shall be deemed to be references to
BankAmerica Corporation and its subsidiaries and affiliates, including the
Bank and, prior to January 1, 1997, BANW. The Bank owns 100% of the Company's
Class B Common Stock.
 
  BAC's transfer to BAMS of certain assets and liabilities of its United
States merchant processing businesses (net assets) was accounted for as a
reorganization of entities under common control and, accordingly, the transfer
of these net assets was accounted for at historical cost. Included in the
transfer of net assets was Seafirst Merchant Services, Inc., a wholly owned
subsidiary of BANW.
 
  During December 1996, BAMS issued 16.1 million shares of Class A Common
Stock in underwritten initial public offerings (the "Offerings") which
generated gross cash proceeds of $249.6 million less the underwriters'
discount and expense totaling $16.7 million, resulting in net cash proceeds of
$232.9 million. In late December 1996, $126.3 million of the net proceeds were
used to pay down the outstanding balance on a revolving line of credit with an
affiliate. The borrowings had been used to finance operations between the
Reorganization and the Offerings.
 
  In connection with the Reorganization, BAMS entered into a definitive
agreement with BAC to acquire its merchant processing businesses in Thailand
(the "Thailand Operations") and the Philippines and to work cooperatively to
allow BAMS to acquire BAC's merchant processing businesses in Taiwan and other
countries in Asia, subject to the approval of the local regulatory authorities
in each country. On June 2, 1997, BAMS acquired the Thailand Operations (net
assets of approximately $132,000) in consideration for the issuance by the
Company of 150,000 shares of Class B Common Stock. The acquisition of the
Thailand Operations was accounted for as a reorganization of entities under
common control and, accordingly, the transfer of net assets was accounted for
at historical cost. The accompanying consolidated financial statements include
the financial results of the Thailand Operations only since June 2, 1997.
Periods prior to June 2, 1997 have not been restated because the impact would
not be material to the consolidated financial statements.
 
  BAMS provides an array of payment processing and related information
products and services to merchants throughout the United States and certain
Asian countries who accept credit, charge and debit cards as payment for goods
and services. BAMS is one of the largest processors of merchant debit and
credit card transactions in the United States.
 
NOTE 2--FINANCIAL STATEMENT PRESENTATION
 
  The unaudited consolidated financial statements of BAMS and its subsidiary,
Seafirst Merchant Services, Inc., are prepared in conformity with generally
accepted accounting principles for interim financial information, the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of
management, all adjustments necessary for a fair presentation of the financial
position and results of operations for the periods presented have been
included. All such adjustments are of a normal recurring nature. These
unaudited financial statements should be read in conjunction with the audited
consolidated financial statements included in BAMS' Annual Report on Form 10-K
for the year ended December 31, 1996. Results for the interim periods should
not be considered indicative of results to be expected for the full year.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The accompanying consolidated financial statements have been prepared as if
BAMS had operated as a separate entity for all periods presented. The
Statements of Operations for the three and six month periods ended June 30,
1996 represent the combined historical results of operations of the United
States merchant processing businesses of BAC. Financial statements for periods
presented subsequent to the Reorganization include the consolidated results of
operations and assets and liabilities of the Company. For simplicity of
presentation, these financial statements are referred to herein as
Consolidated Financial Statements.
 
  Prior to the Reorganization, changes in BAC's equity interest represented
net income of the Company adjusted for net cash transfers to and from BAC.
Additionally, the pre-Reorganization Consolidated Financial Statements include
allocations of certain assets (primarily property and equipment) and expenses
relating to the merchant processing businesses transferred from BAC.
Management believes these allocations are reasonable. Certain of the pre-
Reorganization expenses in the Consolidated Financial Statements are not
necessarily indicative of the costs that would have been incurred if the
Company had performed these functions as a stand-alone entity. Therefore,
prior to the Reorganization, the Consolidated Financial Statements may not
necessarily reflect the Company's consolidated results of operations, changes
in equity and cash flows as they would have been had the Company been a
separate, stand-alone entity during the periods presented. Subsequent to the
Reorganization, the Company performed these functions using its own resources
and purchased services (from BAC and other companies) and was responsible for
the costs and expenses associated with the management of a stand-alone entity.
 
  Certain amounts in prior periods have been reclassified to conform to the
current presentation.
 
NOTE 3--INCOME TAXES
 
  The following is a summary of the components of income tax expense:

  BAMS' estimated annual effective income tax rate for the three and six month
periods ended June 30, 1997 and 1996 was 41.3%. This rate is higher than the
federal statutory tax rate of 35% due principally to state income taxes.
Income taxes payable to BAC were $2.8 million at June 30, 1997 and $3.2
million at December 31, 1996.

NOTE 4--EARNINGS PER COMMON SHARE
 
  Historical earnings per share have not been presented for the three and six
month periods ended June 30, 1996 since the Company had no outstanding stock as
of that date and such information would not be meaningful. Pro forma earnings
per share for the three and six month periods ended June 30, 1996 are listed
below and have been computed by dividing net income by the weighted average
number of common shares outstanding assuming the stock issued in the
Reorganization and Offerings had been outstanding since January 1, 1994.

NOTE 5--CHANGES IN EARNINGS PER SHARE CALCULATIONS
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS No.
128"), which is effective for periods ending after December 15, 1997. BAMS
expects to adopt SFAS No. 128 in the fourth quarter of 1997. Upon the adoption,
BAMS will be required to change the method currently used to compute earnings
per share and to restate all prior periods presented. SFAS No. 128 eliminates
"primary" earnings per share and earnings per share, assuming full dilution,
and requires only "basic" and "diluted" earnings per share. As a result, under
the new requirements, BAMS' computation of earnings per common and common
equivalent share will be replaced by earnings per common share which excludes
any dilutive effects of outstanding stock options and warrants. Also, BAMS'
computation of earnings per common share, assuming full dilution, will be
replaced with diluted earnings per share and will be based on the average
market price of the Class A Common Stock for the period. There is no impact
expected in connection with the adoption of SFAS No. 128 for the three and six
month periods ended June 30, 1997.
 
NOTE 6--RELATED PARTIES
 
  The Company and BAC engage in various intercompany transactions and
arrangements including the provision by BAC of various services to the Company.
Such services are currently provided pursuant to various intercompany
agreements which, among other things, grant to the Company a license to use the
Bank of America name and certain trademarks and service marks in connection
with the Company's business.
 
  Additional services provided under the intercompany agreements include
product distribution services, direct access processing services, direct access
marketing services, system support services, association and network
sponsorship and representation in the credit card associations,
telecommunications services, tax and treasury services, regulatory and
compliance, legal, accounting and audit services and other miscellaneous
support and administrative services.

  The Company believes that the cost of services provided under the
intercompany arrangements are not materially different from the costs that
would have been incurred if the Company were unaffiliated with BAC.
 
NOTE 7--SUBSEQUENT EVENTS
 
  On July 1, 1997, BAMS acquired BAC's merchant processing business in the
Philippines (net assets of approximately $263,000) in consideration for the
issuance by BAMS of 550,000 shares of Class B Common Stock. Based on levels of
sales volume processed, the Philippines and Thailand (see Note 1) merchant
processing businesses represent approximately one percent of BAMS' volume as
of June 30, 1997. Unaudited pro forma financial information is not presented
for the Philippines acquisition as the impact thereof would not be material to
the Consolidated Financial Statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
HIGHLIGHTS
 
  Sales processed by BA Merchant Services, Inc. ("BAMS" or the "Company") for
the first six months of 1997 were up $2.9 billion or 25 percent over the same
period last year and reflect the expansion of internal sales staff. During the
six month period ended June 30, 1997, BAMS opened sales offices in Orlando,
Florida; Atlanta, Georgia; Philadelphia, Pennsylvania; and Boston,
Massachusetts. Additionally, BAMS now has a sales presence in Colorado,
Nebraska and Oklahoma.
 
  BAMS completed the acquisition of two Asian merchant processing businesses
of BankAmerica Corporation ("BAC"). The BAC Thailand and Philippines merchant
processing businesses were acquired on June 2 and July 1, 1997, respectively,
in consideration for the issuance by BAMS of a total of 700,000 shares of
Class B Common Stock. See Notes 1 and 7 to the Consolidated Financial
Statements for a more detailed description of these transactions. These
acquisitions provide BAMS an entry into selected Asian markets which BAMS
believes to have potential for significant future growth. Based on levels of
sales volume processed, these two businesses represent approximately one
percent of BAMS' volume as of June 30, 1997.
 
  During the second quarter of 1997, the Company successfully converted and
integrated its Northwest operations acquired from Bank of America NW, National
Association ("BANW") into its primary merchant accounting system in San
Francisco. With one merchant accounting system for merchants in the United
States, BAMS expects to reduce costs by eliminating duplicate back office
operations and computer systems and restructuring certain customer service
functions.
 
  The Company substantially completed the conversion of United States
merchants from its old transaction processing system to its new advanced
transaction processing system called Hostlink(TM) during the second quarter.
The new system is expected to allow the Company to reduce its dependence on
third party vendors and reduce incremental costs of processing new merchants.
 
RESULTS OF OPERATIONS
 
 Second Quarter Review
 
  Net Revenue--For the three-month period ended June 30, 1997, net revenue was
$36.0 million, up $4.5 million, or 14 percent over the three-month period
ended June 30, 1996. This increase was primarily attributable to a
$1.6 billion or 26 percent increase in sales volume processed over the
comparable prior year quarter. Increased sales volume resulted primarily from
growth in the Company's merchant base through continued emphasis on marketing
and sales growth, including expansion in new sales territories, such as New
York and Chicago. The growth rate in net revenue was lower than that for sales
volume processed primarily as a result of greater sales volume growth in lower
spread business (debit card and high volume merchants) and to a lesser degree,
declining spreads in existing business consistent with historical competitive
trends in the merchant processing industry.
 
  Operating Expense--Total operating expense was $23.7 million for the second
quarter of 1997, an increase of $3.3 million, or 16 percent over the same
period a year ago. This increase was primarily attributable to a 25 percent
($1.6 million) increase in salaries and employee benefits, reflecting growth
in direct sales staff and related support personnel, and a 17 percent ($1.2
million) increase in data processing and communications expense due to
increased authorization expense and data processing contract services related
to growth in transaction volume.
 
 Six Month Review
 
  Net Revenue--Net revenue was $68.9 million for the first six months of 1997,
up 15 percent over the 1996 comparable period. Sales volume processed for the
six months ended June 30, 1997 was $14.3 billion, an increase of $2.9 billion
or 25 percent over the first six months of 1996. The net revenue percentage
growth rate was lower than the sales volume processed growth rate for the same
reasons discussed above.
 
                                       9
<PAGE>
 
  Operating Expense--Total operating expense for the first six months of 1997
increased 19 percent over the 1996 comparable period. On the same comparative
basis, salaries and employee benefits increased 25 percent and data processing
and communications increased 15 percent for the same reasons discussed for the
second quarter. General and administrative expense for the 1997 six month
period increased 21 percent over the comparable 1996 period, due to: (1)
increased merchant supplies expense from increased sales volume processed,
(2) increased administrative expense associated with being an independent
company (including insurance, accounting and financial reporting expense) and
(3) a one-time expense associated with the startup cost of a new merchant.
 
BALANCE SHEET REVIEW
 
  The Company's assets totaled $351.1 million as of June 30, 1997, up $64.4
million from December 31, 1996. The increase was primarily due to increases in
cash and cash equivalents and short-term investments ($101.7 million) and
accounts receivable ($10.4 million), partially offset by a $59.5 million
decrease in drafts in transit. Total liabilities at June 30, 1997 amounted to
$82.7 million, up $48.1 million from December 31, 1996 primarily as a result
of a $40.4 million increase in merchants payable.
 
  The balances in cash and cash equivalents, short-term investments, drafts in
transit and merchants payable can fluctuate greatly depending on the day of
the week in which the reporting period ends. The timing of payments received
from credit card associations and debit card networks, remittances to
merchants and weekend processing influence these balances. While the
individual balances in these accounts at June 30, 1997 were significantly
different from the balances at December 31, 1996, the net total of these
combined accounts was $213.9 million at June 30, 1997, versus $212.1 million
at December 31, 1996. The increase in accounts receivable was due to the
integration of BAMS' Northwest operations into its primary merchant accounting
system in San Francisco which shifted the collection of discount fees from the
last day of the month to the first few days of the next month.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company generated net cash from operating activities of $107.6 million
and $6.8 million for the six month periods ended June 30, 1997 and 1996,
respectively. The increase for the 1997 period was primarily related to the
$59.5 million decrease in drafts in transit and the $40.4 million increase in
merchants payable as described above. Prior to the time BAC transferred its
merchant processing businesses to the Company in the fourth quarter of 1996,
funds generated by the Company's operations and not used for investments were
remitted to BAC.
 
  Working capital improved by $10.8 million to $242.5 million at June 30,
1997. Average cash and cash equivalent and short-term investment balances were
$168.8 million during the six months ended June 30, 1997. The Company
anticipates utilizing these balances for funding the daily cash needs of the
business as well as for acquisitions, strategic technology investments and the
funding of research and product development.
 
  The Company has a commitment for a $70 million revolving line of credit with
an affiliate. The commitment was not utilized as of June 30, 1997.
