                              MERCATOR UNANIMOUSLY
                               REJECTS UNSOLICITED
                            HOSTILE PROPOSAL FROM SSH

          ATTEMPT TO PURCHASE COMPANY LACKS FINANCING AND BUSINESS PLAN

                          WILTON, CT - APRIL 4, 2003 - Mercator Software, Inc.
                          (Nasdsaq: MCTR) today announced that its Board of
                          Directors, after consultation with its financial and
                          legal advisers, has unanimously rejected the March 31,
CORPORATE HEADQUARTERS    2003, unsolicited hostile, un-financed and highly
Mercator Software, Inc.   conditional proposal from Strategic Software Holdings
45 Danbury Road           ("SSH") to acquire all of the Company's outstanding
Wilton, CT 06897-0840     shares for $2.17 per share in cash. In reaching this
Voice:203.761.8600        conclusion, the Mercator Board has determined that
Fax:203.762.9677          this proposal is not in the best interests of the
                          Company or its stockholders.
www.mercator.com

                          J.P. Morgan is serving as financial advisor to
                          Mercator and Jenkens & Gilchrist Parker Chapin LLP is
                          serving as legal counsel.

                          Roy C. King, Mercator's Chairman of the Board, CEO and
                          President, said, "Mercator has well-established
                          strategies and an experienced management team in place
                          that we believe will generate superior value for our
                          stockholders. Our Board does not believe that this
                          dissident proposal is in the best interest of our
                          stockholders. It is our opinion that these dissidents
                          cannot successfully complete what is a highly
                          conditional, unsolicited hostile transaction. Actions
                          like these only serve to distract the Company, our
                          management and our customers and waste resources that
                          could otherwise be deployed to enhance stockholder
                          value."

                          "On April 1, 2003, the Company met with
                          representatives of the dissident group SSH/Broken
                          Arrow," Mr. King said. "What is outrageous is that the
                          dissidents even admitted at the meeting that they had
                          not secured financing for the purported proposal and
                          that they were not prepared to detail any other terms.
                          In addition, the dissidents also refused to discuss
                          their plan for Mercator's business. Rodney Bienvenu,
                          chairman of SSH, even admitted that SSH's intentions
                          for the Company involved a `radical paradigm shift'
                          that would require re-engineering Mercator to, in
                          Rodney's own words, a `unique' and `extremely risky
                          strategy.'"

                          Mercator believes that the dissidents have launched a
                          proxy contest to gain control of the Mercator Board
                          either to sell the Company to themselves as cheaply as
                          possible (if they can find financial backing to
                          implement their intentions for the Company), or to use
                          their control of the Company's Board to engage in what
                          they called an "extremely risky" experiment with the
                          Company's business. As a result

                                                                 [LOGO] MERCATOR


                          we believe the dissidents' interests are clearly in
                          conflict with the interests of other Mercator
                          stockholders.
