STAMFORD, Conn. and Lanham, MD April 13, 2004 -- Pitney Bowes Inc. (NYSE:PBI)
today signed a definitive agreement to acquire all of the outstanding shares of
Group 1 Software, Inc. (Nasdaq:GSOF) for $23 per share, which net of cash on
Group 1's balance sheet, will cost the company approximately $321 million. Group
1 Software is an industry leader in software that enhances mailing efficiency,
data quality and customer communications. Group 1 will become a wholly-owned
subsidiary of Pitney Bowes within its Global Enterprise Solutions segment,
continuing to operate under its current management. Subject to approval by Group
1's stockholders and completion of other conditions, the transaction is expected
to close in the third calendar quarter of 2004. Upon completion, Pitney Bowes
expects the acquisition to be neutral to accretive to earnings, excluding
integration costs, and cash earnings positive in its first twelve months.

This acquisition enhances Pitney Bowes' ability to execute its growth strategies
and deliver added value to customers worldwide, according to Michael J.
Critelli, Chairman and CEO of Pitney Bowes. "The acquisition of Group 1 Software
supports the areas we have previously identified for sustained growth in
customer and shareholder value - mailstream expansion, document management,
global penetration and cross-selling. Software is an increasingly important part
of our value proposition for mailers. Group 1 has a broad range of address
management, data quality, document generation and delivery and marketing
campaign management software applications that complement our existing mailing
software business and products. These capabilities have become even more
important in light of the U.S. Postal Service's recent focus on intelligent mail
and address quality. It will also expand our mail stream participation by adding
3,000 high- and mid-volume mailing customers worldwide."

Mr. Critelli continued, "One of the ways we plan to grow our document management
presence is by integrating mail and documents enterprise-wide across multiple
customer touch points and business processes, which we call customer
communications management (CCM). We feel Group 1's suite of solutions helps lay
the foundation for profitable expansion in the $4 billion, and growing, CCM
market. Its extensive product line, infrastructure and strong presence outside
of the U.S. will enable us to expand our range of mailstream solutions worldwide
and also offers an opportunity for cross-selling to our respective customer
bases. Our brand promise is engineering the flow of communicationTM . In other
words, we help organizations of all sizes get the right message to the right
customer or prospect at the lowest possible cost. The acquisition of Group 1
enhances our ability to add value to every piece of mail and its contents by
reducing its costs, increasing its effectiveness, and enhancing its impact on
customer relationships."

Group 1 Software, headquartered in Lanham, Maryland, began providing postal and
direct mail software in 1982. It has a suite of data quality, mailing
efficiency, customer communications management and data integration applications
that help organizations worldwide maximize the value of their customer and other
data. It has leveraged its leadership position in high volume mailing related
software by extending into customer communications and data quality solutions

for those countries in which it does not have sales offices.

According to Bob Bowen, CEO of Group 1 Software, "We touch growing markets with
$8 billion in current revenue and we view this transaction as a very positive
step toward growing our participation in these markets. Pitney Bowes' expertise,
range of solutions and strong brand recognition in mailing solutions will enable
us together to improve the efficiency and effectiveness of customer
communications."
