TECHNICAL COMMUNICATIONS CORPORATION ANNOUNCES SECOND QUARTER RESULTS

CONCORD, MA, May 12, 2000 – Technical Communications Corporation (NASDAQ: TCCO) today reported that revenues for its second fiscal quarter ended April 1, 2000 were $1,381,000 compared to $1,247,000 in the same quarter a year ago. The Company reported a net loss of $418,000 or $0.32 per share, compared to net income of $147,000 or $0.11 per share in the second quarter of fiscal 1999 which included a previously reported one-time gain on the sale of stock of approximately $1.1 million. Order backlog is currently $450,000 as compare to a year ago amount of $1,165,000.

TCC’s President and Chief Executive Officer Carl Guild stated that “The Q2 results, although not impressive, are consistent with our view that sales recovery will be sporadic during fiscal 2000. We anticipated this slow down during the middle part of the year. However, we believe the order pipeline continues to get stronger and we are working toward capturing new orders with the objective of ending the year on an improved outlook."

Continuing, Mr. Guild said “During this quarter, our sales and marketing teams have introduced our CipherONE™ family of security products, the Cipher X 7200 Internet Protocol Encrypter and the Cipher X 7100 Frame Relay Encrypter to a number of new potential customers. This product introduction has been met with a great deal of enthusiasm from our international customers resulting in several product demonstration trials that are currently being conducted or planned in eight countries. The increasing public and corporate concern with internet communications security, prompted by the publicized effects of virus attacks and hacking is increasing the demand for solutions. Our worldwide customers are starting to react, turning to TCC for rapidly deployable, trusted solutions for their secure networks. We are encouraged by the interest in our new CipherONE product line and expect it to gain market acceptance over time.”
