September 6, 2005

HOUSTON--(BUSINESS WIRE)--Sept. 6, 2005--Hanover Compressor Company (NYSE:HC) announced today that the Houston-based company has been awarded a $12.5 million contract to develop a natural gas storage facility for Underground Storage, LLC, in southeast Harris County, Texas. Underground Storage, LLC, a subsidiary of Texas Brine Company, LLC, is also based in Houston.

The facility will utilize an existing salt dome cavern to store nearly 3 billion cubic feet (BCF) of natural gas to supply the Houston area markets. Hanover will supply all surface equipment as well as the engineering, project management and construction services for the project. AMEC Paragon, also of Houston, will support Underground Storage, LLC, as the owner's engineer and Hanover, by providing civil, structural and detailed engineering.

The project is scheduled for completion during the second quarter of 2006. This will give Underground Storage a significant time-to-market advantage for the new facility that will serve the energy marketplace, according to Mickey McDonald, Vice President for U.S. Operations with Hanover Compressor.

"Time truly is money in today's energy market. Hanover's total solution package provided Underground Storage with the time-to-market and economic advantages that they were seeking," Mr. McDonald said. "This is also an important win for our United States marketing efforts, as Hanover continues to broaden its total solutions offering with turn-key equipment and construction packages to meet our customer's needs. We look forward to working with Underground Storage and AMEC Paragon on this project."
