                A D S FINANCIAL SERVICES SOLUTIONS(TM) ANNOUNCES
                     SIGNING OF DEFINITIVE MERGER AGREEMENT

FOR IMMEDIATE RELEASE: QUINCY, Mass.-(Business Wire)-July 22, 2003 - A D S
Financial Services Solutions(TM) ("ADS") (NASDAQ: ADSC) today announced that it
has entered into an agreement and plan of merger (the "Merger Agreement") with
ADS Acquisition Company, LLC ("Acquisition Company"), a wholly-owned subsidiary
of ADS Acquisition Parent, LLC ("Acquisition Parent"). The sole members of
Acquisition Parent (the "Principals") are Robert W. Howe, Chairman and Chief
Executive Officer of ADS, William H. Gallagher, President and Chief Operating
Officer (and a director) of ADS, Lee M. Kennedy, a director of ADS, and
affiliates of General Atlantic Partners, LLC, a global private equity firm that
is a major stockholder of ADS. David C. Hodgson, a director or ADS, is a
Managing Member of General Atlantic Partners, LLC. The Principals together hold
approximately 65% of the Company outstanding common stock.

Under the Merger Agreement, each share of Company common stock outstanding at
the time of the Merger (other than 3,400,000 shares held by the Principals),
will be converted into the right to receive $3.25 per share in cash or
approximately $32.3 million in the aggregate (the "Merger Consideration"). As of
the date hereof, the Company has approximately 13,136,124 shares issued and
outstanding. Under the Merger Agreement, Acquisition Company will merge into the
Company, and the Company, will become a wholly-owned subsidiary of Acquisition
Parent.

The Board of Directors of the Company, acting on the recommendation of a special
committee composed entirely of disinterested directors of the Company's Board,
unanimously approved and adopted the Merger Agreement and recommended that the
Company's stockholders approve the Merger Agreement. The special committee's
financial advisor has opined that, as of July 21, 2003, the Merger Consideration
was fair from a financial point of view to the Company's stockholders other than
the principals. The closing of the Merger is subject to customary conditions,
including approval of the Company's stockholders.

As soon as practicable, the Company will file a proxy statement relating to the
Merger with the Securities and Exchange Commission (SEC), and will schedule a
special meeting of the Company's stockholders to vote on a proposal to approve
the Merger Agreement. Acquisition Parent and each of the Principals intend to
vote their shares of the Company's common stock in favor of the Merger
Agreement, which will be sufficient to approve the Merger Agreement and the
Merger. Although the Merger Agreement can be approved without the affirmative
vote of any public stockholders, the public stockholders will be entitled to
contractual appraisal rights substantially equivalent to statutory appraisal
rights under Massachusetts law.

THE COMPANY'S STOCKHOLDERS WILL BE ABLE TO OBTAIN A FREE COPY OF THE PROXY
STATEMENT THAT THE COMPANY WILL FILE WITH THE SEC WHEN IT BECOMES AVAILABLE AT
THE SEC'S WEB SITE AT WWW.SEC.GOV. THE PROXY STATEMENT AND OTHER DOCUMENTS FILED
WITH THE SEC BY THE COMPANY MAY ALSO BE OBTAINED FOR FREE FROM THE COMPANY BY
