NEW YORK, Feb. 19, 2002 — Caminus Corp., a provider of software solutions and strategic consulting services to energy markets worldwide, today announced that a number of energy utilities, producers, pipelines, gas and power marketers, physical and financial traders, and integrated energy companies licensed software spanning all of the company’s product lines during the fourth quarter of 2001.

Among the new customers that selected Caminus software during the company’s fourth quarter are Eni S.p.A.; Hess Energy Trading Company, LLC; Nicor Enerchange, LLC; RWE Trading Americas, Inc.; Sequent Energy Management, L.P.; and Prior Energy, a wholly owned subsidiary of TECO Solutions, Inc. In addition, a number of existing customers, including American Electric Power Service Corporation (AEP) and PG&E Gas Transmission Corporation, licensed additional software from Caminus’ industry- product line during the fourth quarter.

Nicor, RWE, Sequent and Prior Energy were among the companies that selected Caminus’ Nucleus software suite to manage their integrated energy transaction management needs, including trading, risk, credit, scheduling, accounting, and back office functions. Representing the gas and power marketing, trading, and utility sectors of the wholesale energy markets, these energy firms cited Nucleus’ integrated, end-to-end business functionality and speed of implementation as major factors in their decisions processes. Nucleus is the only software suite in the industry that enables customers to enter and evaluate transactions, manage physical and financial risks, schedule physical energy transactions, account and settle deals, and comply with strict financial controls on a single, integrated, multi-commodity platform.

Eni S.p.A. and Hess Energy Trading were among the firms that chose Caminus’ Zai*Net software suite over a number of competitors. These successes each exemplify the depth of transaction and risk management functionality, as well as the diversity of business uses, that the Zai*Net software suite offers to the marketplace.

Eni S.p.A., the seventh largest energy producer in the world, selected Zai*Net to manage its corporate-wide risk management, valuation, and reporting requirements across multiple commodities, traded instruments, and operating units. Hess Energy Trading, one of the world’s largest market makers in crude oil derivatives, plans to use the Zai*Net Suite to conduct advanced risk analytics, such as Monte Carlo VaR and potential credit exposure, as it enhances its presence in the financial gas and power trading markets.

Caminus’ Physical Gas software solution suite was also selected by a number of customers, including AEP and PG&E Gas Transmission Corporation, to manage their transaction management needs. AEP selected the Caminus Pipeline software suite to manage its Houston Pipe Line gas transmission and storage system. A unit of the PG&E National Energy Group, PG&E Gas Transmission Corporation also chose the Caminus Pipeline system to streamline its scheduling and pipeline management operations across its natural gas pipeline system in the Pacific Northwest and California, including Gas Transmission Northwest (GTN) and North Baja Pipeline, LLC.

“Our success in winning new business across all major product lines demonstrates Caminus’ continued leadership in all major competitive energy software segments, including trading and transaction management, energy risk management, advanced analytics, and power and gas operations and scheduling,” said Caminus COO John Andrus.

“Our ability to provide a single source solution for all major energy market players across North America and Europe has led to the continued growth of our industry- roster of blue chip clients as well as to the deepening of our relationships with existing customers.”
