Business/Energy Editors & Technology Writers

HOUSTON--(BUSINESS WIRE)--April 11, 2000

PROS Revenue Management and Altra Energy Technologies Inc. announced today a business alliance to integrate PROS' revenue optimization tools with Altra's transaction management software suite. The two companies will also build a consulting practice around the deployment of these margin-enhancement tools.

PROS Revenue Management is the world's leader in revenue management science and a pioneer of revenue management for the energy and airline industries. Altra Energy Technologies Inc., together with its subsidiaries, provides end-to-end transaction management solutions to the wholesale energy market. Altra also operates Altrade(TM), the leading independent online energy trading exchange.

"Inclusion of PROS proven revenue optimization capabilities into Altra's product suite will provide our customers with an integrated product solution that extends beyond operational efficiencies into margin enhancement," said Paul Bourke, president and CEO of Altra Energy Technologies. "The marriage of Altra's e-commerce products and PROS' revenue optimization tools will, for the first time, provide the energy industry with complete end-to-end software solutions, offering the same documented, dramatic benefits enjoyed by other industries that have embraced revenue management."

PROS and Altra, working in tandem with a selected Beta customer, plan to begin the development work required to optimally integrate the prosRM Capacity Optimization System and the prosRM Storage Optimization Systems with the Altra Gas and Altra Pipeline products. The products logically rely on and add value to the data contained in and processed by each other's systems. This relationship will enable Altra to provide these state-of-the-art revenue-enhancing systems to all of its new and existing customers. Deployment on a commercial basis is expected early third quarter, 2000.

The prosRM Capacity Management System maximizes profitability from wholesale gas marketing by optimally routing gas from supply to market, minimizing transportation and fuel costs, while maximizing buy/sell opportunities at pools and interconnects. The system performs this complex optimization in seconds and generates GISB compliant EDI nominations that are fed back to the Altra transaction management products.

"The extraordinary increase in scheduling speed and quality provided by the prosRM Capacity Management System will transform the relationship between Altra Gas traders and schedulers enabling unrivaled levels of efficiency and profitability," said Matt Johnson, vice president, Energy Revenue Management for PROS.

The prosRM Storage Revenue Optimization System maximizes revenue by optimally capturing the price arbitrage opportunities present in the gas futures market, within the physical constraints of a park-and-loan or storage service. The optimization engine at the heart of the system simultaneously evaluates capacity positions, limits, targets and deliverability along with market pricing and basis input to create a revenue optimal storage sales plan.

The tool also supports capacity traders in the execution of the optimized plan through individual-customer deal negotiations. The optimal solutions provided by the prosRM Storage Revenue Optimization System increase the cycling of storage capacity and have been measured to provide seven- to 25-percent increases in related revenue.

"The prosRM Storage Revenue Optimization System will provide Altra's pipeline and marketing customers with a proactive tool to capture unprecedented value from their storage assets," Johnson said.
