New development agreement with Bryan Research and Engineering (BR&E), the leader in sour gas processing and dehydration

Aspen Technology, Inc. (Nasdaq: AZPN) today announced a joint development agreement with Bryan Research and Engineering (BR&E) of Bryan, TX, for a multi-product interface to allow integrated operation of BR&E's technology (TSWEET(R), PROSIM(R), ProMax(R)) within the Aspen Engineering Suite(TM) (AES) products.

"This agreement furthers our goal of streamlining and integrating the process engineering workflow and ensuring that 'best-in-class' technologies are available to all of our customers," said Larry Evans, Chairman and CEO of Aspen Technology. "It enhances our petroleum industry capabilities and supplements our leading edge simulation, equipment design and physical properties capabilities with additional detailed knowledge of crucial technologies within the refinery."

Companies should be able to achieve immediate benefits from this partnership through an enterprise-wide deployment and utilization of AspenTech's steady state simulation and optimization product, Aspen Plus(R) 11.1, which can access BR&E's detailed property database. This interfacing of complementary software technologies within Aspen Plus will allow the benefits of the BR&E technology to be multiplied throughout the engineering and asset optimization business processes supported by AES.

"We are very excited about the opportunity to integrate and co-develop our software products with AspenTech," said Jerry Bullin, President of Bryan Research and Engineering. "This is a significant validation of our technology and allows customers of the Aspen Engineering Suite to benefit from our industry expertise."

The interface will be commercially available in a service pack to the AES 11.1 release, previously announced for Spring 2002. This interface allows the usage and reference of BR&E's physical property models within Aspen Plus. Additional development is ongoing and will be made available with future updates to Aspen Properties(TM) and Aspen Plus.
