CONCORD, MA, November 20, 1998 – Technical Communications Corporation (NASDAQ:TCCO) today announced the settlement of litigation initiated by Philip Phalon and Dr. Mahmud Awan, which had been pending in Middlesex County, Massachusetts Superior Court since February 1998. Litigation regarding the tabulation of the voting results of the Company’s 1998 annual stockholders’ meeting held August 14, 1998 also has been settled.

In connection with the settlement of these matters, Dr. Awan and David Brown will join the Company’s Board of Directors, with Dr. Awan serving as Chairman of the Board. The Company’s current Chairman and Chief Executive Officer, Carl H. Guild, Jr., will assume the role of Vice Chairman of the Board and will continue as Chief Executive Officer/President. Current Board members Philip Phalon and Herbert Lerner will resign from the Board, which will now consist of Mr. Guild, Mitchell Briskin, Donald Lake, Thomas Peoples, David Brown, Robert Lessard and Dr. Awan. These changes are effective immediately. The Company’s Board will remain classified, with each director serving a "staggered" term and Messrs. Awan and Briskin deemed elected at the August 14 stockholders’ meeting for a term ending in 2001.

The settlement agreement and standstill agreement executed in connection with the settlement of the above described litigation include provisions requiring among other things (i) that the Company reimburse the Phalon/Awan Group’s expenses in payments aggregating $395,000, (ii) the dissolution of the Phalon/ Awan/Martindale/Bregman 13(d) Group, and (iii) that the former proxy contestants abide by certain standstill provisions until October 1, 2000.

"Today’s announcement is clearly an excellent result for TCC and its shareholders," said Mr. Guild. "The settlement of this litigation removes a great burden from the Company in terms of expense and management time. Equally as important, TCC’s Board has been strengthened by the election of Dr. Awan, an entrepreneur in high technology with wide experience in international commerce. In addition, Mr. David Brown brings a wealth of experience in strategic business planning. The Company can now focus all its efforts on executing its strategy to become the leading supplier of mission-critical security systems worldwide."

Commenting on today’s developments, Dr. Awan stated "I am pleased that TCC and my group have reached an agreement that permits the resolution of all disputes and the dismissal of the various lawsuits that have been filed. I am also

pleased to join the Board of TCC and look forward to working with the current Board members to advance the interests of TCC and its shareholders. Although the circumstances have been unusual, I am now confident that the actions of the current board members were taken in good faith with the interests of the corporation and its shareholders paramount in their minds. I look forward to working with these individuals and I have confidence in them and in our ability to ensure that TCC remains a leader in its field."
