              DATRON SYSTEMS AGREES TO BE ACQUIRED
                    BY THE TITAN CORPORATION

     VISTA, CA -  June 25, 2001 - Datron Systems Incorporated
(Nasdaq: DTSI) today announced it has entered into a definitive
agreement to be acquired by The Titan Corporation (NYSE: TTN), a
leading-edge technology company that creates, builds and launches
technology-based businesses, for approximately $51 million, or
$16.00 per fully-diluted share, in Titan common stock.  Datron
common stock closed at $14.00 on Friday, June 22, 2001.
Consummation of the transaction, which will be accounted for as a
purchase, is subject to customary closing conditions, will
include a tender for exchange of at least a majority of Datron's
outstanding shares, and is expected to close by the end of
Datron's second quarter, September 30, 2001.

     Commenting on the announcement, David A. Derby, Datron
Systems' chairman, president and chief executive officer, stated,
"We are firmly committed to maximizing the tremendous growth
potential of Datron's mobile broadband communications and public
safety wireless network markets, the continued growth of our
radio communications products and the resurgence of our satellite
antenna systems business.  We believe Titan's e-tenna subsidiary,
which is developing unique radio frequency technologies, its
radio communications business, familiarity with long-term
government contracting as well as its size and distribution
capabilities are a strategic fit for Datron that will enable the
combined companies to better pursue the growth opportunities in
these markets.

     "With its patented antenna technology, Datron has
established a strong leadership position in the emerging market
of providing broadband satellite data to airliners worldwide.  We
were first to fly on a commercial airliner nearly five years ago
and have maintained our technological and market lead through the
protracted maturation of this market.  The added strength
provided by Titan sharply improves the probability that Datron's
substantial investments in this arena will lead to additional
growth opportunities in the airborne broadband market."

     Under terms of the definitive agreement, Titan will first
commence an exchange offer for all of the outstanding shares of
Datron common stock.  The exchange offer will be followed by a
merger in which Titan will acquire, at the same exchange ratio,
the remaining shares of Datron not previously acquired in the
exchange offer.  All outstanding options to acquire Datron common
stock will be assumed by Titan and converted into the right to
purchase shares of Titan common stock.


     Also under terms of the definitive agreement, which has been
approved by the Board of Directors of both companies, Datron
stockholders and option holders are expected to receive a total
equity value of approximately $51 million if Titan's ten-day
average closing share price is equal to or greater than $19.00
and less than or equal to $26.00 per share at the price
determination date, which is five (5) trading days prior to the
expiration of the initial offering period.  If Titan's average
closing share price is equal to or greater than $17.50 and less
than  $19.00, the equity value will decrease ratably from
approximately $51 million to approximately $47 million. At a
Titan average closing share price of less than $17.50, Datron has
the right to terminate the definitive agreement subject to a
Titan option to assure a minimum equity value of approximately
$46 million. If Datron does not elect to terminate if the average
closing share price is less than $17.50, the equity value would
be less than $46 million.  If Titan's average closing share price
is greater than $26.00 and equal to or less than $27.50, the
equity value will increase ratably from approximately $51 million
to approximately $54 million. At a Titan average closing share
price of more than $27.50, Titan has the right to terminate the
definitive agreement subject to a Datron option to agree to
receive a maximum equity value of approximately $56 million.
Philpott Ball & Werner is acting as financial advisor to Datron
on the transaction.

     The foregoing summary is a general description of certain
pricing and related terms contained in the definitive agreement
for the transaction, and is qualified in its entirety by
reference to the definitive agreement, a copy of which will be
filed with the Securities and Exchange Commission.
