Houston, February 5, 2007 – Hanover Compressor Company (NYSE: HC) (Hanover) and Universal Compression Holdings, Inc. (NYSE: UCO) (Universal)announced today that their boards of directors have approved a stock-for-stock merger of equals and that the companies have signed a definitive merger agreement.

Under the terms of the merger agreement, Hanover stockholders will receive 0.325 shares of the new company for each share of Hanover they own, and Universal stockholders will receive 1.0 share of the new company for each share of Universal they own. Based on the closing market prices for the shares of both companies on February 2, 2007, the combined company would have an equity market capitalization of approximately $3.8 billion. It is

anticipated that Hanover stockholders initially will own about 53 percent and Universal stockholders about 47 percent of the new company. The merger is expected to be tax free to stockholders of both companies.

“The combination of Hanover and Universal brings together two highly respected companies in the natural gas compression and production and processing equipment fabrication industry. Both companies have an excellent team of employees known for their dedication to customer service,” said Stephen A. Snider, Universal’s Chairman, President and Chief Executive Officer. “Operating under a new corporate name, we will be able to fully leverage our combined capabilities to provide an enhanced level of customer support and a wider product and service offering to meet the full compression services and production and processing equipment needs of our customers worldwide.”

John E. Jackson, Hanover’s President and Chief Executive Officer, said, “This merger will create a new company with a portfolio of high quality assets, products, services and financial capabilities to generate enhanced value for stockholders of both companies. It also affords excellent opportunities for the employees and customers of both companies to benefit from our combined global expertise in an increasingly competitive market place.”

Stephen Snider added, “The combination also provides a larger pool of domestic contract compression customers and equipment that can be offered for sale to Universal Compression Partners, L.P. (NASDAQ: UCLP) over time. The transfer of these domestic contract compression assets to Universal Compression Partners should further improve our cost of capital, and enable us to provide our services on a more efficient basis to our customers over the long term.”

Following the merger, Stephen Snider will serve as President and Chief Executive Officer and as a director of the new company. Gordon T. Hall, Hanover’s Chairman, will serve as Chairman of the Board of the combined company, which will consist of ten directors, five designated by each company. John Jackson will serve as a director of the new company.

The merger is expected to be accretive to earnings per share for stockholders of both companies in 2008 after achieving expected annualized pre-tax cost savings of approximately $50 million. These synergies are expected to arise from the closure of overlapping facilities, increased operational efficiencies and reduction of corporate overhead.

Additional Information about the Merger

The merger agreement provides for the formation of a new holding company that will own all the stock of both Hanover and Universal. The new company will be headquartered in Houston, and its common stock is expected to be listed on the New York Stock Exchange.

The merger is subject to various conditions including approval of the stockholders of both Hanover and Universal and customary regulatory approvals, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. It is anticipated that the closing of the merger will occur in the third quarter of this year. Hanover and Universal intend to file a proxy statement/prospectus with the Securities and Exchange Commission as promptly as practicable after each company files its 2006 Annual Report on Form 10-K.

Hanover Fourth Quarter Financial Results Update

Hanover also announced that, for the three months ended December 31, 2006, it expects to report revenue of $465 million to $470 million, up from $424 million in the third quarter; income from continuing operations before income taxes and minority interest in the range of $27 million to $31 million, compared to $23 million in the third quarter; and backlog of $808 million, including $325 million for compression at December 31, 2006 compared to $689 million, including $192 million for compression at September 30, 2006. With respect to fourth quarter income taxes, Hanover has not yet finalized its tax analysis, but it currently expects the effective tax rate in the fourth quarter to be less than the mid-40 % range, which Hanover had expected at the time of its third quarter 2006 conference call. Hanover will

provide more specific information in its fourth quarter earnings conference call, which it expects to conduct on Thursday, February 15, 2007.

Universal Fourth Quarter and Full Year Earnings Updates

Universal also announced updated revenue and earnings guidance for the fourth quarter and full year 2006. For the three months ending December 31, 2006, Universal expects revenue of $250 million to $255 million and earnings per diluted share of $0.66 to $0.70; this compares to previously reported guidance of revenue of $240 million to $250 million and earnings per diluted share of $0.70 to $0.74. The reduced earnings guidance is primarily the result of higher labor costs in the domestic contract compression segment. For the twelve months ended December 31, 2006, Universal expects revenue of $945 million to $950 million and earnings per diluted share of $2.84 to $2.88; this compares to previously reported guidance of revenue of $935 million to $945 million and earnings per diluted share of $2.88 to $2.92. Universal’s fabrication backlog was approximately $289 million at December 31, 2006.
