CAMBRIDGE, MA., October 22, 1999 - Excelergy Corporation, the technology leader for the deregulated energy industry, has upgraded its advanced billing and customer care software, called Excelergy ABPTM (Advanced Billing Platform) 3000. ABP 3000 now offers the most flexible, robust billing and customer care system available for the retail energy market today. This new upgrade is available immediately.

The upgrade enables suppliers to seamlessly enroll new customers across state and jurisdictional lines at a lower cost, providing suppliers access to a larger market base. Excelergy's products integrate the latest technology, including XML, to advance customer choice. It improves upon its predecessor (ABP 1200) in several critical areas:

* Support of Multi-State, Multi-Jurisdictional Environments promotes customer choice by enabling suppliers to do business in various states simultaneously, allowing them to expand their customer bases across state lines without the traditional constraints from billing or CIS systems. For example, ABP 3000 is now enrolling customers in both Pennsylvania and New
Jersey.

• Enhanced Transaction Management Tools enable suppliers to maintain complex trading partner relationships in a more efficient and cost-effective manner - with fewer errors.
• Flexible Data Extender allows suppliers the ease of customizing the data model structure independently by allowing for additional data fields without programming modification.
• Rate Designer II offers increased flexibility and power to help suppliers better serve their customers with customized index pricing and more sophisticated rate computations. The system also supports flat, block, time of use, real time, and user-defined contract values.

XML Conversion Tool is an XML-based conversion API (application program interface) that facilitates the movement of data from legacy systems into ABP 3000.

"ABP 3000 gives suppliers a substantial edge in what is becoming the New Energy Economy" said Cary Bullock, president of Excelergy. "As a result of its technology, it is faster, more efficient and has greater functionality than ever before. ABP 3000 is designed to meet the challenges deregulation poses to both local distribution companies and energy services providers by incorporating significant scalability and trading partner communications directly into our web-integrated technology."

Separately, Philippe Frangules, Excelergy's vice president of e-commerce, announced today that Excelergy changed the name of its dynamic Web-based auction site for energy procurement to e-ChoiceNet (www.e-ChoiceNet.com). Formerly energymarketplace.com, e-ChoiceNet is the first Web site to Offer energy choice information and real-time e-commerce benefits for every segment of the new deregulating retail energy market. "Excelergy chose the name e-ChoiceNet to reflect our commitment to Customer choice** which is the hallmark of the rapidly expanding deregulated energy market," said Frangules.

* Flexible Data Extender: For example, ABP 3000 comes with standard customer information fields such as name, address, phone number. Using the flexible data extender, suppliers can include additional customer information such as school district or date of birth without programming changes.

**Customer Choice: Just as deregulation in the telecommunications industry allowed customers to freely choose their long distance telephone carriers, deregulation in the energy industry is allowing for the first time consumers and businesses to choose their providers of electricity and/or natural gas.
