Item 5.  Other Events.

         On March 1,  1999,  Aydin  Corporation,  a  Delaware  corporation  (the
"Company"),   entered  into  an  Agreement  and  Plan  of  Merger  (the  "Merger
Agreement") with L-3 Communications Corporation, a Delaware corporation ("L-3"),
and Angel  Acquisition  Corporation,  a Delaware  corporation  and  wholly-owned
subsidiary of L-3 (the "Purchaser").

         The Merger Agreement provides,  among other things, for the acquisition
by L-3 of all of the outstanding shares of the Company's common stock, par value
$1.00 per share (the "Shares"), through (a) a tender offer (the "Offer") for all
Shares at a price of $13.50  per share,  net to the  seller in cash (the  "Offer
Price"), and (b) a second-step merger pursuant to which the Purchaser will merge
with and into the Company,  with the Company as the surviving corporation in the
merger (the "Merger"),  and all  outstanding  Shares (other than Shares owned by
the Company,  L-3 or any  wholly-owned  subsidiary  of L-3 and other than Shares
held by any dissenting shareholders) will be converted into the right to receive
the Offer Price in cash.

         The Offer is conditioned upon, among other things,  there being validly
tendered prior to the expiration date of the Offer and not withdrawn a number of
Shares which, together with any Shares owned by L-3 or the Purchaser, represents
at least a majority of the Shares  outstanding  on a fully diluted basis and the
expiration  of  any  applicable  waiting  periods  under  the  Hart-Scott-Rodino
Antitrust  Improvements Act of 1976, as amended. The conditions to the Offer are
set forth in Annex A to the Merger  Agreement.  The Merger is subject to various
closing conditions,  including,  without limitation, the receipt of any required
shareholder approval and L-3 purchasing Shares pursuant to the Offer.

         The Merger  Agreement  and the press  release  issued by the Company in
connection therewith are filed herewith as Exhibits 99.1 and 99.2, respectively,
and  are  incorporated  herein  by  reference.  The  description  of the  Merger
Agreement  set forth  herein does not purport to be complete and is qualified in
its entirety by the provisions of the Merger Agreement.
