                                                                             -----------------  ------------------

 
NOTE 2. LONG-TERM DEBT
 
    As of December 27, 1997, the Company had a $3,500,000 line of credit at a
rate of prime plus 1/2 of 1%. This line of credit is secured by a pledge of
substantially all the assets of the Company and is due to mature on May 1, 1998.
Availability under the line of credit had been reduced by $819,419 for
outstanding standby letters of credit (as of December 27, 1997) and borrowings
of $1,000,000 obtained on December 26, 1997. The Company expects to increase its
line of credit during fiscal 1998 in order to accommodate letters of credit and
working capital requirements associated with current and projected customer
orders. Borrowings under the line of credit are expected to be repaid late in
the current fiscal year when one particular order for approximately $7.4 million
is shipped and payment is received from the customer. There were no borrowings
under the line of credit during the quarter ended December 28, 1996.
 
    On November 17, 1989, the Company established the Technical Communications
Corporation Employees' Stock Ownership Trust (the Trust) for the benefit of its
employees. During 1990 and 1991, the Trust borrowed $1,212,500 and $1,287,488,
respectively, from two banks, and purchased 190,350 shares of the Company's
common stock at fair market value. The Company acted as a guarantor on the
outstanding loans and, as a result, recorded the principal balance of such loans
on its balance sheet as short-term and long-term debt with an offsetting charge
to "ESOP Deferred Compensation" within the Stockholders' Equity section.
 
    On April 30, 1997, the Company provided a loan of $82,702 to the Trust in
order to pay off the remaining balance of the 1990 bank loan. This new loan,
which bore interest at 9% per annum, required equal monthly payments of
principal of $3,446, commencing on May 31, 1997. On August 28, 1997, the Company
provided a second loan of $472,222 to the Trust in order to pay off the 1991
bank loan. This second Company loan to the Trust bore interest at 13.6% per
annum and required equal monthly

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2. LONG-TERM DEBT (CONTINUED)
principal payments of $9,838 beginning on September 28, 1997. The Employee Stock
Ownership Plan (ESOP) was terminated by the Board of Directors effective October
1, 1997, at which time these loans to the Trust were eliminated and the
remaining 25,732 of unallocated suspense shares were reacquired by the Company
as treasury stock.
 
    Until the ESOP's termination, the Company made contributions to the Trust
sufficient to pay all principal and interest on the various loans when due.
Because the payment of principal resulted in the release of shares from
collateral, which shares were then available for allocation to employees, the
principal portion of these contributions was recorded as compensation expense.
Such contributions were, therefore, expensed to compensation and interest when
they were made or accrued.
 
    On May 31, 1995, the Company completed an asset purchase of the secure
communications business of Datotek, Inc. This acquisition was funded partly by
the Company's own capital and partly through loans amounting to $2,250,000 from
two banks. These loans, which were payable in equal installments of principal
over a period of five years, plus interest at The First National Bank of
Boston's prime rate plus 1/2 of 1%, were paid in full during November 1996.
 
NOTE 3. EARNINGS PER SHARE
 
    In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) No. 128, "Earnings per Share," which
established standards for computing and presenting earnings per share (EPS) for
entities with publicly held common stock. SFAS No. 128 is effective for periods
ending after December 15, 1997, including interim periods, and early adoption
was not permitted. After the effective date, all prior period EPS data presented
must be restated to conform with the provisions of this statement, which
includes the presentation of both a "Basic" and a "Diluted" EPS. Basic EPS has
been computed by dividing net income by the weighted average number of shares of
common stock outstanding during period. In computing diluted EPS, only stock
options that are dilutive; those that reduce earnings per share, have been
included in the calculation of EPS using the Treasury Stock Method. Exercise of
outstanding stock options is not assumed if the result would be antidilutive,
such as when a net loss is reported for the period or the option exercise price
is greater than the average market price for the period presented.

NOTE 4. COMMITMENTS AND CONTINGENCIES
 
    The Company is not currently party to any lawsuit, and is not aware of any
material pending legal proceedings. See Part II, "Other Information," Item 1,
"Legal Proceedings."
 
                                     Page 6

            PART I, ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
The Company is in the business of designing, manufacturing and marketing
communications security equipment. The Company receives orders for equipment
from customers which may take several months or longer to manufacture and ship.
With the exception of long-term contracts where revenue is recognized under the
percentage of completion method, the Company generally recognizes income on a
unit-of-delivery basis. This latter method can cause revenues to vary widely
from quarter to quarter and therefore quarterly comparisons of revenue may not
be indicative of any trend.
 
The Company's backlog of firm orders as of December 27, 1997 was $8,389,548
representing a decrease of $2,251,141 from $10,640,689 reported as of September
27, 1997. The decrease is predominantly the result of recognizing $1,528,472 in
revenue under the percentage of completion method on a long-term contract to be
delivered later this fiscal year. The Company expects to deliver substantially
all of this backlog in fiscal 1998.
 
Net sales for the quarter ended December 27, 1997 and December 28, 1996, were
$2,935,048 and $3,058,114, respectively. This decrease of 4% in first quarter
net sales was due to both the timing of deliveries on specific contracts and the
revenue value of the work completed on the long-term contract noted above.
 
Gross profit for the first quarter of fiscal year 1998 was $1,363,962, as
compared to gross profit of $1,853,362 for the first quarter of fiscal year
1997. This represented a 26% decrease in gross profit. Gross profit expressed as
a percentage of sales was 46% in the first quarter of fiscal 1998 as compared to
61% in the first quarter of the prior year. This decline as a percentage of
sales was primarily the result of the Company's shipment of two large orders
with unusually high gross profit margins in December 1996 and the conservative
recording of a low gross profit margin on the previously mentioned long-term
contract accounted for under the percentage of completion method.
 
Operating expenses for the first quarter of fiscal 1998 were $1,560,133 
compared to operating expenses in the first quarter of fiscal 1997 of 
$1,834,078. This decrease of $273,945, or 15%, was primarily due to a 
decrease in engineering consulting expense for product development, 
capitalization of Keynet-TM-II, the Company's next generation of key and 
device management system software, as well as a reduction in sales 
commissions related to the timing of shipments.

The Company incurred a net loss of $128,719 for the first quarter of fiscal 1998
as compared to after-tax income of $35,951 for the same period last year. The
decline in profitability for the quarter is attributed to the decrease in gross
profit margin as described above.
 
LIQUIDITY AND CAPITAL RESOURCES
 
Cash and short-term investments decreased by $635,371 or 34% to $1,241,377 as of
December 27, 1997, from a balance of $1,876,748 at September 27, 1997. This
decrease was primarily due to the loss of $128,719 for the period, a $730,647
increase in inventory, and an increase in unbilled revenue of $1,528,472 as a
result of the long-term percentage of completion contract discussed under
Results of Operations. This reduction in cash has been partially offset by the
Company's borrowing of $1,000,000 under its existing line of credit, as
previously discussed in Note 2, and a $775,560 increase in accounts payable and
accrued expenses. The current ratio declined to 2.4:1 at December 27, 1997,
compared to

                                     Page 7

3.2:1 as of September 27, 1997. The decline in the ratio was caused primarily by
the $1,000,000 borrowing under the line of credit and the increase in accounts
payable and accrued expenses.
 
Information on the Company's long-term debt is to be found on Page 4, Note 2,
"Long-Term Debt" of this Form 10-Q.
 
Management anticipates no unusual capital expenditures during the remainder of
fiscal 1998. As discussed in Note 2, however, Management anticipates that the
Company will need to increase its line of credit above the current $3,500,000
limit in order to accommodate letters of credit and working capital requirements
associated with current and projected customer orders. No assurances can be
given that such an increased line of credit will be available on satisfactory
terms, if at all. If the Company is unable to obtain an increase or renewal of
its existing line of credit, its operations can be substantially adversely
affected.
