Jacobs Receives Contract Ceiling Increase from United States Special Operations Command.

TULLAHOMA, Tenn. -- Jacobs Engineering Group Inc. (NYSE:JEC) announced today that a subsidiary company received a $180 million ceiling increase to its Acquisition, Logistics, Management, and Business Operations Support (ALMBOS) contract with the United States Special Operations Command (USSOCOM). Under the ALMBOS contract, Jacobs provides these services to USSOCOM headquarters staff, its Service components, and the Theater Special Operations Commands.

Originally worth up to $120 million, this contract is now worth up to $300 million. There are currently more than 270 Jacobs employees supporting USSOCOM worldwide under the contract, which went into effect May 1, 2002. ALMBOS is the follow-on contract to the System Engineering and Technical Assistance II contract USSOCOM awarded to Jacobs in 1997.

The increase in the contract ceiling coincides with the award of an additional year to the original five-year contract term. This is the first of three one-year incentive award terms, bringing the contract to six years with the possibility of extending to eight years. Jacobs serves as the prime contractor for the effort and draws support from nine large business subcontractors and four small business subcontractors.

In making this announcement, Jacobs President Craig Martin stated, "With the highly unpredictable global landscape precipitated by the events of September 11, 2001, USSOCOM is more critical than ever given their unique responsibilities for organizing, training, equipping, and leading special operations forces for their worldwide mission in peace and war. We are proud to continue our support to this important client by providing a wide range of acquisition, business, and technical services through this contract."

Jacobs, with over 35,000 employees and revenues approaching $5.0 billion, provides technical, professional, and construction services globally.
