                                  Press Release
                         Titan to Acquire Datron Systems

SAN DIEGO, June 25, 2001 -- The Titan Corporation (NYSE: TTN) today announced
that it has entered into a definitive agreement to acquire Datron Systems
(Nasdaq: DTSI), a Vista, California based provider of radio and satellite based
communications systems and broadband communications products for government and
commercial markets for approximately $16.00 per Datron share or $51.2 million in
Titan common stock. The purchase price represents approximately .8x Datron's
fiscal 2001 revenues of $62.3 million. In addition to reducing Titan's overall
debt by approximately $9 million, the transaction is expected to be accretive to
Titan's earnings once the integration of Datron into Titan is completed later
this year. The acquisition will be accounted for as a purchase and is expected
to close by the end of the third quarter.

         Founded in 1969 as a defense contractor, Datron has pioneered the
development of antennas to track airborne rockets, missiles, weaponry, and
spacecraft. Datron has developed expertise in remote sensing, image processing,
satellite tracking and antenna manufacturing with products including remote
sensing satellite earth stations, image processing software, tracking systems,
and voice and data communication radio products.

         More recently, Datron has developed the leading technology for bringing
broadband voice, video and data communications to commercial airlines and the
lowest profile direct broadcast satellite TV antenna available for land and
marine markets. Datron is also positioned to capture potential business from the
federal public safety wireless network market through the development of its
line of digital radios. Titan will also exploit the potential for synergies
between Datron's consumer products business, which is targeting the mobile
broadband communication markets, and Titan's e-tenna subsidiary, a developer of
unique radio frequency technologies for the wireless market.

         "We are fortunate to be able to acquire in Datron, a business focused
on Titan's core competency, communication systems, in addition to technology
with commercial potential. Given Datron's unique expertise in securing foreign
government customers, the acquisition will also allow us to significantly expand
our presence in foreign countries," said Gene W. Ray,





Chairman, President and CEO of Titan. "We believe Datron's extensive expertise
in antenna systems and communications products is highly complementary to our
internal capabilities and their operations can be easily integrated into Titan.
We are also very excited about Datron's prospects in the area of providing the
antenna technology for high speed Internet access to commercial airlines."

         Under the 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.

         The total consideration to be paid by Titan in the acquisition may
fluctuate based upon fluctuations in Titan's stock price. If the ten-day average
closing sales price for Titan's common stock (ending five trading days prior to
the consummation of the exchange offer) is between $19.00 and $26.00, the Datron
securityholders will be entitled to that number of Titan shares having an
aggregate value of approximately $51 million. If the average Titan closing price
is greater than $26.00 and less than or equal to $27.50, then Titan will issue
approximately 1,970,000 shares of Titan common stock to the Datron
securityholders. If the average Titan closing price is less than $19.00 and
greater than or equal to $17.50, then Titan will issue approximately 2,700,000
shares of Titan common stock to the Datron securityholders. If the average Titan
closing price is greater than $27.50, then the Datron securityholders will be
entitled to that number of Titan shares having an aggregate value of
approximately $56.3 million and if the average Titan closing price is less than
$17.50, then the Datron securityholders will be entitled to that number of Titan
shares having an aggregate value of approximately $46.1 million.

         The exchange offer and the merger is subject to the satisfaction of
customary closing conditions, including the tender for exchange of at least a
majority of Datron's outstanding shares.

         The foregoing summary is a general description of certain pricing and

qualified in its entirety by

with the Securities and Exchange Commission.
