TECHNICAL COMMUNICATIONS CORPORATION
ANNOUNCES RECEIPT OF $2M CONTRACT

CONCORD, MA, September 1, 1999 - Technical Communications Corporation (NASDAQ: TCCO) today reported that it has received a contract to supply encryption equipment for use in the air defense systems of a foreign government. The contact is valued at $2,000,000 and was awarded by a foreign company in support of ongoing requirements. Receipt of this order increases TCC’s current backlog to over $3,000,000. TCC expects to ship this equipment within the next three months.

"TCC’s performance in the third quarter still remains below our expectations." said Carl Guild, President & C.E.O. "However, the worldwide markets, most notably the Middle East, are showing significant signs of increased activity. We are seeing progress on several large orders we have been pursuing for many months and we take this as a sign that overall business in the area is opening up. The pipeline for us has been strong all year and we are starting to see the benefits of our efforts".

Carl Guild, TCC’s President and Chief Executive Officer, stated “The release of this order is an indication that the procurement delays we have experienced during the last two years may be starting to shrink. National budget uncertainties are being reckoned with in certain of TCC’s key Mid-East, Latin American and Asian markets and planned procurements are beginning to proceed. We have a number of foreign projects in the procurement cycle and expect them to progress more rapidly. "
