                      GARTNER REPORT COMMENTS ON MERCATOR'S
                             STRENGTHS AND PROSPECTS
               BELIEVES MERCATOR WILL SUCCEED IN CONTEST WITH SSH

Dear Colleagues:

     On April 8, Gartner issued their assessment of the unsolicited, hostile
takeover proposal from Strategic Software Holdings.

     Highlights of the report, which is attached, include:
     o    Mercator is positioned to participate in the general market recovery.
     o    Mercator continues to exploit historical strength in transformation
          and electronic data interchange.
     o    Mercator has shifted its strategy and R&D investments away from raw
          middleware technology to more-complete vertical solutions,
          particularly in healthcare and finance
     o    Mercator is wisely rebuilding its core architecture to make its
          product more scalable and manageable.
     o    Near term, enterprises should continue to consider Mercator products
          for tactical use, especially for healthcare, finance and enterprise
          resource planning projects where its technology is particularly
          appropriate.
     o    Strategic decisions involving the use of Mercator as a
          general-purpose, long-term enterprise integration backbone face
          greater risk until the outcome is clear.
     o    Gartner expects the SSH fight to be resolved by 1 June 2003.

     Any customer that is an existing customer of Gartner Group can speak
directly with Roy Schulte, lead Gartner analyst for the integration broker
suites market. Roy King, Ken Hall, and Jonathan Cohen are available to
personally speak with customers about this matter.

Sincerely,

The Corporate Communications Team

MERCATOR'S REJECTION OF BUYOUT BID SIGNALS ITS HOPE FOR THE FUTURE

GARTNER BELIEVES MERCATOR SOFTWARE'S ATTEMPTS TO FEND OFF A HOSTILE TAKEOVER
WILL LIKELY SUCCEED, BUT FOR NOW STRATEGIC-LEVEL COMMITMENTS TO MERCATOR
PRODUCTS INVOLVE SOME INCREASED RISK.


EVENT: On 4 April 2003, the board of directors of Mercator unanimously rejected
Strategic Software Holdings' (SSH's) unsolicited bid to buy Mercator for about
$75 million in cash. SSH made its offer on 31 March 2003.

FIRST TAKE: The outcome of this hostile takeover attempt depends on Mercator's
ability to convince most of its shareholders that the company's value will be
higher if it remains under current management. Events could take one of the
following directions:
o    Mercator could win the battle outright, and the company's direction would
     change little or not at all.
o    It could lose outright and undergo major change.
o    It could run to the arms of a friendly buyer that would probably make
     significant changes.

Mercator's management says it can prevail against SSH and that does not seek a
friendly buyer, and Mercator seems to have a better than even chance of avoiding
purchase altogether.

The battle complicates a fitful corporate recovery that has gone on for two
years. Mercator's troubles began before the software industry downturn. The
company had problems in its administrative infrastructure and sales force, and
lost people and sales momentum in 2001. The whole software market slumped just
as Mercator got its new management team and revamped sales strategy going.
Nevertheless, Mercator has evolved its products to stay competitive by adding
features such as Web services support and business process management (BPM). The
vendor continues to exploit its historical strength in transformation and
electronic data interchange but has shifted its strategy and R&D investments
away from raw middleware technology to more-complete vertical solutions,
particularly in healthcare and finance. Mercator is also wisely rebuilding its
core architecture to make its product more scalable and manageable. Mercator is
thus positioned to participate in the general market recovery, assuming that the
whole integration middleware market does recover. Its weak overall 2002 results
were still in line with most of its competitors. Product license revenue slipped
24 percent, from $59 million in 2001 to $45.1 million in 2002. However, after
strong 4Q02 results, Mercator's direction appeared positive.

In the near term, enterprises should continue to consider Mercator products for
tactical use, especially for healthcare, finance and enterprise resource
planning projects where its technology is particularly appropriate. However,
strategic decisions involving the use of Mercator as a general-purpose,
long-term enterprise integration backbone for many different kinds of
applications face greater risk until the outcome of the battle against SSH is
clear. Gartner expects the SSH fight to be resolved by 1 June 2003, at which
time the strategic risk will likely drop to its previous level.
