    DATRON RESCHEDULES ANNUAL MEETING TO OCTOBER 11, 2001

VISTA, Calif., July 3, 2001 (BUSINESS WIRE) -- Datron Systems
Incorporated (Nasdaq: DTSI) today announced it is rescheduling
its annual meeting of stockholders scheduled for August 14,
2001 to October 11, 2001.

     Datron and The Titan Corporation (NYSE: TTN) entered into an
agreement and plan ofmerger and reorganization on June 24, 2001.
Under the terms of the agreement, Titan will commence an exchange
offer for all outstanding shares of common stock of Datron as soon as
practicable.  If Titan acquires more than 50% of Datron's
outstanding shares in the exchange offer, Datron will merge with
a wholly owned subsidiary of Titan.  Datron would expect to call
a meeting of the stockholders to approve the merger in September
or early October.  If Titan does not acquire more than 50% of
Datron's shares in the exchange offer, Datron will hold its
annual meeting on October 11.  Rescheduling the annual meeting is
expected to avoid substantial costs and effort involved in
holding two stockholders meetings within a few weeks of each
other.  For this reason the Board of Directors has rescheduled
the annual meeting from August 14 to October 11, and has set
September 4, 2001 as the record date for the October 11 meeting.
Datron will withdraw its preliminary proxy statement filed with
the SEC and refile preliminary proxy materials at a time closer
to the meeting date.
