Business/Technology Editors

Major new client agreements in North America, Europe and Asia contribute to highest Q2 sales and revenue numbers in company history

Based in part on several major, to-be-announced new client agreements in North America, Europe and Asia, Excelergy Corporation reported today it achieved the highest Q2 sales and revenue numbers in company history for the quarter ending June 30, 2002. Lexington, Massachusetts-based Excelergy is a world leader in high performance software products for critical business processes in the energy/utility industry and other restructuring markets.

"Excelergy has now achieved these kinds of successive results for our clients, partners and stakeholders for seven straight quarters. In addition to setting year over year records, Q2 also paralleled our all-time quarterly sales record of Q4 2001," said Bill Mahoney, president and chief executive officer of Excelergy. "The cornerstone for our continued success is our company-wide commitment to delivering outstanding satisfaction levels to our growing community of global clients. These results are a clear acknowledgment of the superior performance of all Excelergy colleagues, which has always been behind the unparalleled value and return on investment associated with our software technology."

During the second quarter, Excelergy signed a number of significant agreements with new clients in North America, Europe and Asia, including SembCorp Utilities, Singapore's leading integrated energy provider. The company also announced major new agreements with Green Mountain Energy Company and Australia's ETSA Utilities. Additional new client announcements--involving global powerhouses in both the energy/utility and broadband industries--are planned for the coming weeks. In addition, Excelergy's Client Services division once again contributed significantly to Excelergy's record Q2 results by delivering exceptional performance levels, a key indicator of outstanding client satisfaction.

"These benchmark quarterly results," added Mahoney, "are a tremendous validation of Excelergy's long-term market and technology strategies. We are executing these despite the ongoing slump in global technology markets and in the energy industry in particular. To reinforce this momentum we've built, we are taking proactive steps to raise our company's performance to even higher levels. For example, we recently redistributed some of our resources to aggressively respond to growing market demand for our software platforms in Europe and Asia. This redeployment is but one example of how we are leading with action to assure continued growth and profitability through the second half of 2002 and beyond."

Excelergy also earned several global technology and industry awards during the quarter. In April, for the second year in a row, the company was awarded a coveted spot in the Red Herring 100 list of the top private and public companies in the world. In May, it won recognition on the UPSIDE Hot 100 list as one of the world's top private technology firms. In June, the company was awarded the "Premium Product Award" from Power & Gas Marketing Magazine for Excelergy Trader BackOffice(TM), a high performance software platform that automates the scheduling, settlement, and market communications processes for companies participating in real-time physical energy markets worldwide.

Other key achievements in Excelergy's second quarter include:

-- Continuation of the successful implementation of the Italian wholesale power exchange on an aggressive timetable;

-- Most successful and widely-covered product launch in company history with Excelergy Trader BackOffice;

-- Roll-out of the latest version of collaborative information exchange and transaction management product Excelergy eXACT(R);

-- Election of chairman and former CEO of Concerto Software, Alphonse Lucchese, to the Excelergy board of directors, adding operations, sales and marketing expertise to the company.
