L-3 COMMUNICATIONS AGREES TO ACQUIRE AYDIN CORPORATION

New York --(BUSINESS WIRE)-- March 1, 1999 -- L-3 Communications (NYSE: LLL)
today announced that it has signed a definitive agreement to acquire Aydin
Corporation (NYSE:AYD). Under the terms of the agreement, L-3 Communications
will purchase all of the outstanding common stock of Aydin for $13.50 per share
in cash. The total value of the transaction is approximately $72.3 million,
before reductions for cash on hand of approximately $11.3 million at the end of
February and planned asset sales. The transaction is expected to be accretive
to planned asset sales. The transaction is expected to be accretive to L-3
Communications earnings in 1999 and is expected to close in the first half of
1999.

      Headquartered in Horsham, Pennsylvania, Aydin is a leader in
technologically advanced telemetry, communications and other electronic products
and systems for military, space, government and commercial customers.

      "Aydin broadens the marketplace for our existing telemetry and
instrumentation and communications businesses," said Frank C. Lanza, chairman
and chief executive officer of L- 3 Communications. "This business extends our
participation into flight test instrumentation for a number of programs,
including the Joint Strike Fighter (JSF) for the U.S. Navy, Marine Corps and Air
Force and the United Kingdom Royal Navy."

      "Aydin's communications business gives us entry into a larger
international customer base for our earth stations, gateways and fixed wireless
loop products," continued Mr. Lanza. The company also provides both domestic and
international customers with terminals for intelligence satellite systems and a
variety of communications products, including transponders and multiplexers.

      "In 1998, Aydin extensively restructured its operations to focus on its
core businesses," said Mr. Lanza. "Aydin's management divested certain non-core
operations and took other actions that resulted in a return to profitability
from operations in the fourth quarter before unusual charges and a one-time
gain. As part of L-3 Communications, we believe opportunities remain for
additional improvements in profitability due to further efficiencies in
operations, synergies and corporate consolidation."

      Under the acquisition agreement, a tender offer will be commenced by a
wholly owned subsidiary of L-3 Communications. The transaction is subject to the
receipt of a majority of Aydin's shares outstanding in the tender offer,
regulatory approvals and other customary closing condtions.
