Business Editors

LEXINGTON, Mass.--(BUSINESS WIRE)--Oct. 17, 2001

Excelergy(R) Corporation, the world's first provider of groundbreaking open co-action software products to the energy/utility industry and other restructuring markets, today reported its most successful third quarter in its history. Compared to a year ago, Excelergy's year-to-date bookings (new sales) have grown 300 percent and its revenues are up 70 percent.

"Q3 marked the fourth consecutive quarter Excelergy has effectively met or exceeded our plan," said Bill Mahoney, Excelergy's president and chief executive officer. "Our continued high performance and steady growth speak volumes about the excellence of Excelergy's technology, our engineering, our energy sector knowledge, and our speed. Behind these company differentiators are the most talented and hard-working group of colleagues I've ever had the privilege of working with. Few companies anywhere can match growth numbers like ours in today's economy."

For the third consecutive quarter, Excelergy generated more than 170 percent of its quarterly target for repeat business, a key indicator of client satisfaction. Also during the third quarter of 2001, Excelergy signed several new North American clients, including Indiana-based energy marketer Vectren Source and Virginia-based marketer ACN Energy. It also signed a significant add-on agreement with Ohio-based FirstEnergy Services.

Internationally, Excelergy continued its rapid implementation at Powercor Australia, and signed a substantial add-on agreement with the United Kingdom's Maverick Energy. It also significantly expanded its global sales and channels force during the quarter.

"While we continue to deliver proven, innovative product solutions to our growing global client base, software industry consolidation - particularly in the wholesale and retail energy sectors - continues to eliminate competition and open up broader market opportunities for our products," added Mahoney. "We will continue to leverage our unparalleled object technology platform to capitalize on those opportunities in the months and years ahead."

Other significant Excelergy events and announcements in the third quarter include the following:

- PennWell's New Energy Economy named Excelergy's industry-pioneering chairman,
Cary Bullock, one of the Top 50 People in Energy IT.

- Excelergy's Mahoney joined the National Energy Marketers Association's
Executive Committee.

- Excelergy signed its first broadband industry partnership with systems
integrator Xperts Inc. to deliver groundbreaking solutions to the companies'
joint broadband and energy clients.

- Excelergy released two new products: Excelergy Customer Explorer(TM) and
Excelergy Partner Explorer(TM). These products allow the customers and partners
of Excelergy clients to easily investigate their own invoices, accounts and
inquiries - drilling down to individual line items as desired

- in real-time over the Internet. Each has been implemented

and is in use with a major North American client.

Excelergy's open co-action software products combine dynamic office collaboration, straight-through processing, and actionable business intelligence to enable clients to enter new markets faster, work with trading partners more effectively, provide superior customer and partner service, and settle and bill more efficiently and accurately than their competition.
