HoustonStreet Achieves Record Trading Activity

Company Continues to Build Liquidity on Physical Crude Oil and Refined Products Trading Platforms

PORTSMOUTH, N.H., November 7, 2001 - HoustonStreet announced today that it achieved record trading activity on its physical crude oil and refined products platforms during the month of October. Based on market size estimates from a Forrester Research report and feedback from traders, the Company estimates that it has now captured approximately 10% of the overall physical oil market.

"We're focused on the physical market where we continue to make good progress on adding new traders and liquidity to our platforms," said Frank Getman, HoustonStreet's President and CEO. "We've seen significant growth in our refined products markets such as conventional regular gasoline. In October alone, we traded over 6.4 million barrels of refined products."

"The fact that all bids and offers on HoustonStreet are firm is a major advantage," said Cindy Neggia, Director of Crude and Products. "In an uncertain market traders want to go to where they can see actual transactable prices and not just what is being talked about."
