Titan Shareholders to Receive $23.10 Per Share in Cash

SAN DIEGO, CA — June 3, 2005 — The Titan Corporation (NYSE:TTN), a leading national security solutions provider, and defense contractor L-3 Communications (NYSE:LLL) have entered into a definitive agreement for L-3 to acquire Titan in an all-cash merger at a price of $23.10 per share. The total value of the transaction, including L-3’s assumption of Titan’s debt, is expected to be approximately $2.65 billion at closing.

The transaction, which has been approved by the boards of directors of each company, is subject to approval by Titan shareholders, the execution and court filing of definitive settlements of the litigation described below, government regulatory reviews and other closing conditions contained in the merger agreement. Titan’s board of directors is unanimously recommending that Titan’s shareholders approve the transaction.

Dr. Gene W. Ray, Titan chairman, president and chief executive officer, said, “I am confident that this transaction is in the best interests of our shareholders, our customers, and our employees.

“This merger with L-3 will create a company with greater resources and the operational flexibility to offer our customers an even broader spectrum of innovative systems and quality solutions,” he added.

Concurrently with entering into the merger agreement, Titan entered into memoranda of understanding to settle securities law class actions and derivative suits pending in both Federal and State courts in California and the Delaware Court of Chancery. These settlements will become effective after the closing of the merger and receiving court approvals. Details of the settlements may be found in Titan’s 8-K to be filed with the SEC.

While no assurances can be made, Titan expects the merger to close prior to year end and possibly by the end of the third quarter.
