BILLERICA, MA, May 21, 2008 - CSP Inc. (Nasdaq:CSPI), a provider of IT Solutions, systems integration services and dense cluster computing systems, has been named to the “Globe 100” list of top performing public companies in Massachusetts, The Boston Globe announced today.

Based on a composite score derived from financial data for the four quarters ending December 31, 2007, CSPI was ranked 72nd among Massachusetts-based companies whose stock is publicly traded on NASDAQ, New York Stock Exchange or American Stock Exchange. It is the second time that CSPI has been included in the Globe 100.

"These companies represent the resiliency of Massachusetts business, surviving recessions, merger manias, and dramatics shifts in their industries," said Shirley Leung, business editor of the Boston Globe.

To qualify for the Globe 100, a company must have been public for the entire 2007 calendar year and have reported a positive net income for both 2006 and 2007.

"We are delighted to be recognized by The Boston Globe based on these objective measurements," said Alexander R. Lupinetti, CSP chairman and chief executive officer. "To be acknowledged as a top performing company during these times of economic challenge brings great pride to our employees who continue to develop and deliver cutting edge products and services to meet our customer’s critical needs."

The Globe 100, celebrating its 20th anniversary in 2008, ranks Massachusetts-based public companies based on financial data from the four quarters ending closest to December 31, 2007, and for corresponding quarters a year earlier.
