                      BA MERCHANT SERVICES (BAMS) TO BE
                     MERCHANT PROCESSOR FOLLOWING MERGER

        SAN FRANCISCO, May 29, 1998 - BA Merchant Services, Inc. (NYSE-BPI) 
today announced that BankAmerica Corporation and NationsBank Corporation have 
determined that BAMS will be the principal merchant servicer for their combined 
organization following the merger. Patrick Phillips, who will be head of Card 
Services for the combined entity, will manage the relationship with BAMS.

        The merger is subject to regulatory and shareholder approval.

        NationsBank currently offers merchant services through Unified
Merchant Services, a venture between NationsBank and First Data Merchant
Services. NationsBank will seek to renegotiate its existing relationship with
First Data Merchant Services in order to assure that there is a single
provider of merchant services for the combined entity. The outcome of these
negotiations and their impact on BAMS are yet to be determined.

        A subsidiary of Bank of America NT&SA, BA Merchant Services, Inc. was 
incorporated in October, 1996, and provides an array of electronic payment 
processing and related products and services to merchants who accept credit, 
charge, and debit cards as payment for goods and services throughout the 
United States and certain Asian countries.
