NEWS RELEASE

                     AYDIN CORPORATION AGREES TO BE ACQUIRED
                        BY L-3 COMMUNICATIONS CORPORATION

  Sale at 39% Premium to Current Market Will Cap Efforts to Enhance Shareholder
             Value Undertaken in 3Q 1998 by The Full Value Committee

NEWTOWN,  PENNSYLVANIA,  March 1, 1999: Aydin Corporation  (NYSE:AYD)  announced
today  that  it  has  entered  into  a  definitive  merger  agreement  with  L-3
Communications  Corporation  (NYSE:LLL)  providing for the acquisition by L-3 of
all of the outstanding common shares of Aydin Corporation at $13.50 per share in
cash. The transaction was unanimously approved by Aydin's Board of Directors.

The sale of Aydin,  at a price which  represents a 39% premium to the  Company's
closing market price on February 26, will culminate efforts undertaken last Fall
by The  Full  Value  Committee,  a group  of Aydin  Stockholders  led by  Warren
Lichtenstein,  the Company's current Chairman. As previously announced in August
1998, the Company engaged  PricewaterhouseCoopers  Securities, LLC to assist the
Company in evaluating  potential  strategic  alternatives to enhance shareholder
value.

The  merger  agreement  with L-3  Communications  provides  for a  wholly  owned
subsidiary  of L-3 to promptly  commence a cash  tender  offer to acquire all of
Aydin's  outstanding shares at $13.50 per share. The tender offer is conditioned
on,  among other  things,  the valid tender of such number of shares which would
represent at least a majority of Aydin's  outstanding  shares on a fully diluted
basis and receipt of  regulatory  approvals.  The tender offer is not subject to
financing  and is expected to commence by Friday.  Following  completion  of the
tender  offer,  L-3 will be  entitled  to  designate  a majority of the Board of
Directors  of Aydin.  The parties  will  complete a  second-step  cash merger at
$13.50 per share as promptly as practicable  following  completion of the tender
offer.  The  transaction  has a total  value  of  approximately  $72.3  million,
including the cash-out of outstanding stock options and warrants.

Commenting  on the  execution  of the  merger  agreement,  Warren  Lichtenstein,
Chairman  of Aydin,  stated:  "Aydin  Corporation  has  engaged in an  extensive
process,  with the  assistance  of  PricewaterhouseCoopers  Securities  LLC, the
Company's  financial advisor,  in soliciting and evaluating third party interest
in a sale of the Company.  We are  convinced  that the current  $13.50 per share
offer by L-3 Communications is in the best interests of our shareholders."

Steel Partners II, LP, a limited partnership controlled by Mr. Lichtenstein, and
Sandera  Partners,  L.P.,  and  Newcastle  Partners,   L.P.(which  entities  are
associated  with other  directors  of Aydin  Corporation),  and certain of their
respective affiliates and associates, which beneficially own an




aggregate of approximately 12% of the outstanding  Aydin shares,  have agreed to
tender  such  shares  provided  that  the  acquisition  agreement  has not  been
terminated.  As of March 1, 1999,  Aydin had  approximately  5.2 million  shares
outstanding.

A  detailed  discussion  of the  rationale  for the Aydin  Corporation  Board of
Directors'  recommendation  will be contained  in a  Solicitation/Recommendation
Statement on Schedule  14D-9,  which is expected to be filed with the Securities
and  Exchange  Commission  early  next week and will be  mailed to  shareholders
shortly thereafter.
