ATTENTION: MERCATOR SOFTWARE INC. STOCKHOLDERS

Strategic Software Holdings has initiated an effort to replace the current
Mercator board of directors with a new slate of directors that have a wealth of
skill and experience in technology, the software industry and specifically the
enterprise applications space.

The reasons for this change are numerous. Under the current Board of Directors
and senior management:

o    Mercator's stock price has plummeted from a high of $142 per share on March
     7, 2000 to just $1.33 per share as of March 12, 2003 (see the historical
     stock price chart);

o    Over the same period, Mercator's stock has underperformed its peers and the
     NASDAQ Composite, as shown in the chart.

o    Mercator's market position collapsed from 3rd to 10th between 1999 and
     2001, and its Enterprise Application Integration (EAI) market share fell
     from 10% to 4.7% over the same period;

o    Mercator's revenue has declined dramatically, down from $138.3 million to
     $111.9 million in 3 years;

o    Yet Mercator's research and development spend has been wasted, increasing
     from 15% to 19% of revenue over the same time from 2000 to 2002.
