Titan Announces Extension of Exchange

Offer and Consent Solicitation Relating to

Outstanding 8% Senior Subordinated Notes Due 2011

San Diego, CA, March 12, 2004—The Titan Corporation (NYSE: TTN) announced today that it has extended its exchange offer and consent solicitation relating to its outstanding 8% Senior Subordinated Notes due 2011. The exchange offer and consent solicitation will expire at 1:00 p.m. EST on April 12, 2004, which is the same date to which Titan intends to adjourn the special meeting of its stockholders for consideration of its pending merger with Lockheed Martin Corporation (NYSE: LMT). As of the close of business on March 11, 2004, approximately 99.2% of the $200,000,000 aggregate principal amount of 8% Senior Subordinated Notes issued and outstanding had been tendered for exchange with Deutsche Bank Trust Company Americas, the exchange agent for the exchange offer and consent solicitation. As announced on February 25, 2004, all of the tendered notes were accompanied by the holders’ consents to the proposed amendments to the indenture governing the notes and the related registration rights agreement made by Titan for the benefit of the note holders.

Titan has entered into a supplemental indenture with the indenture trustee to effect the proposed amendments to the indenture and has entered into an amendment to the registration rights agreement providing for its termination. Accordingly, the proposed amendments to the indenture and the registration rights agreement are effective and the notes tendered with consents are irrevocable; however, the proposed amendments will not become operative until immediately prior to the completion of Titan’s pending merger with Lockheed Martin. If the merger is completed, Lockheed Martin will guarantee the surviving entity’s obligations as the obligor of the notes. If the merger is not completed, the amendments will not become operative. Until that point, the indenture and the registration rights agreement, without giving effect to the proposed amendments, will remain in effect.

Holders who validly tendered and delivered consents prior to 5:00 p.m., New York City Time, on February 25, 2004 will receive a consent fee equal to 1.0% of the principal amount of the notes validly tendered by the holders if the merger is completed. Other holders may tender their notes and consent to the proposed amendments, without receiving the consent fee, at any time prior to the expiration date.
