DRC to Acquire High Performance Technologies, Inc.

--- Acquisition Enhances Information Technology Consulting and Systems Engineering Capabilities ---

--- Broadens Presence in Healthcare and Other High Growth Markets ---

Andover, Mass. – June 03, 2011 – Dynamics Research Corporation (Nasdaq: DRCO), a leading provider of innovative management consulting, engineering, and technology solutions, today announced that it has signed a definitive agreement to acquire privately-held High Performance Technologies, Inc (HPTi), a leading provider of high-end technology services, primarily to the federal healthcare and military technology markets.

HPTi reported revenue of $90 million for calendar 2010 with nearly 80 percent of sales aligned with DRC’s target growth markets, including healthcare, cyber security, intelligence, civilian financial agencies and homeland security.  HPTi, a high-end technology solutions provider, synthesizes disciplined architecture and development with emerging technologies across high priority federal civilian and defense agencies such as the Veterans Administration, Treasury, Department of Justice, intelligence agencies, and selected advanced military technology areas.  HPTi is a highly regarded, go-to partner for its customers known for solving some of the highest priority, most technically advanced problems - from high performance computing to enterprise wide systems engineering and architecture.  With 44 percent of staff holding masters degrees or above, HPTi possesses extraordinary capabilities to meet customer needs for emerging technologies.

“HPTi has an outstanding reputation in the federal marketplace with the capabilities to solve some of the most complex, technical challenges faced by government agencies,” said Jim Regan, DRC’s chairman and chief executive officer.  “I have known the company and members of its management team since inception. HPTi is among the best led organizations in our industry and an outstanding fit for DRC.  HPTi’s management team has done a tremendous job of extending the company’s technical abilities, which originated in the defense arena, to other federal growth markets.  We are very enthusiastic about having the HPTi staff with their impressive capabilities join the DRC team.”

Tim Keenan, HPTi’s president, added, “In DRC we have found an alignment of not only core values but also of market approach.  We are truly pleased to be part of what we believe will be a go-to source of technology solutions for our combined clients.”  Mr. Keenan will report to Mr. Regan in the position of corporate development and strategy advisor.  Scott Miller, HPTi’s chief operating officer, also will report directly to Mr. Regan, continuing his leadership role for HPTi operations.

HPTi has approximately 440 employees located primarily in the National Capital Region with principal offices in Reston and Ballston, Virginia.

Terms of the merger agreement include a cash price of $143 million with closing anticipated for June 30, 2011 following the expiration of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.  For tax purposes, the transaction will be treated as an asset purchase resulting in tax benefits to DRC, estimated at $23 million.  HPTi earnings before interest, taxes, stock compensation, depreciation and amortization (EBITDA) for the twelve months ended March 31, 2011 was $11.9 million on revenue of $97 million.

Concurrent with the transaction, DRC will replace its current credit facility with a $110 million five-year term loan, a $20 million revolving credit facility and $40 million of subordinated debt with a six-year term.  The senior credit facility will be led by Bank of America and will include SunTrust Bank and PNC Bank as Lead Arrangers.  Ares Capital Corporation will provide the subordinated debt financing, which was arranged by B Riley.  Total debt at closing is anticipated to be approximately four-times the most recent twelve months pro-forma EBITDA of $39 million adjusted for the combined businesses.  “We are pleased to have financial support of a bank group, which is among the strongest and most experienced in our industry,” said Dave Keleher, DRC’s senior vice president and chief financial officer.

KippsDeSanto & Co. is acting as exclusive financial advisor to HPTi in this transaction.
