                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) COMPANY OPERATIONS
 
        Technical Communications Corporation and its wholly-owned subsidiaries
    (the Company) operate in one industry segment: the design, development,
    manufacture, marketing, distribution and sale of communications security
    devices and systems.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
        The consolidated financial statements include the accounts of the
    Company and its wholly-owned subsidiaries, TCC Foreign Sales Corporation, a
    qualified Foreign Sales Corporation (FSC), and TCC Investment Corporation, a
    Massachusetts Security Corporation. All significant intercompany accounts
    and transactions have been eliminated in consolidation.
 
USE OF ESTIMATES
 
        The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities and
    disclosure of contingent assets and liabilities at the date of the financial
    statements, and the reported amounts of revenues and expenses during the
    reporting period. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
        Cash and cash equivalents include demand deposits at banks, and
    certificates of deposit and other investments (including mutual funds)
    readily convertible into cash. Cash equivalents are stated at cost, which
    approximates market value.
 
INVENTORIES
 
        Inventories are stated at the lower of cost or market. Cost is
    determined by the first-in, first-out method.
 
EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
        Equipment and leasehold improvements are stated at cost. Depreciation
    and amortization are computed using the straight-line method over the
    estimated useful life of the asset. When assets are retired or otherwise
    disposed of, the cost and related accumulated depreciation are removed from
    the accounts, and any resulting gain or loss is recognized in income for the
    period. The cost of maintenance and repairs is charged to income as
    incurred; significant renewals and betterments are capitalized.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

CAPITALIZED SOFTWARE COSTS
 
        Certain computer software costs are capitalized in accordance with
    Statement of Financial Accounting Standards No. 86, "Accounting for the
    Costs of Computer Software to be Sold, Leased, or Otherwise Marketed," and
    are reported at the lower of unamortized cost or net realizable value. Upon
    initial product release, these costs are amortized based upon the higher of
    (a) the ratio of current revenues to total anticipated revenues of the 
    products, or (b) the straight-line method, over two or three years.
 
RECOGNITION OF REVENUE
 
        The Company generally recognizes revenue upon shipment of products,
    except in the case of long-term contracts for which the revenue is
    recognized under the percentage-of-completion method.
 
STOCK-BASED COMPENSATION
 
        Statement of Financial Accounting Standards No. 123, "Accounting for
    Stock-Based Compensation," encourages, but does not require, companies to
    record compensation cost for stock-based employee compensation plans at fair
    value. The Company has chosen to continue to account for stock-based
    compensation using the intrinsic value method prescribed in Accounting
    Principles Board No. 25, "Accounting for Stock Issued to Employees," and
    related Interpretations.
 
INCOME TAXES
 
        The Company records income tax expense in accordance with Statement of
    Financial Accounting Standards No. 109 "Accounting for Income Taxes," which
    requires the use of the liability method in accounting for income taxes.
    Under the liability method, deferred income taxes are recognized at current
    income tax rates to reflect the tax effect of temporary differences between
    the consolidated financial reporting and tax basis of assets and
    liabilities.
 
WARRANTY COSTS
 
        The Company provides for warranty costs based on a percentage of sales.
    The percentage is adjusted periodically in accordance with actual
    experience.
 
EARNINGS PER SHARE
 
        Earnings per common share are based on the weighted average number of
    shares outstanding during the year using the treasury stock method. The
    effect of assumed conversion of dilutive stock options is not material.
 
        In March 1997, the Financial Accounting Standards Board issued Statement
    of Financial Accounting Standards (SFAS) No. 128, "Earnings per Share,"
    which establishes standards for computing and presenting earnings per share
    for entities with publicly held common stock. SFAS No. 128 is effective for
    periods ending after December 15, 1997 and early adoption is not permitted.
    Had SFAS No. 128 been adopted as of September 29, 1996, there would have
    been no effect on the Company's reported earnings per share for the year
    ended September 27, 1997, including all quarterly earnings per share.

FISCAL YEAR-END POLICY
 
        The Company by-laws call for its fiscal year to end on the Saturday
    closest to the last day of September, unless otherwise decided by its Board
    of Directors. Fiscal years 1997, 1996, and 1995 ended on September 27, 1997,
    September 28, 1996, and September 30, 1995, respectively.

(5) DEBT
 
        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 guarantor on these loans and, as a result, recorded the
    principal balance of such loans on its balance sheet as long-term debt with
    an offsetting charge to "ESOP deferred compensation" within the
    Stockholders' Equity section.
 
                                    Page AR-13



             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

        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 bears interest at 9% per annum, requires 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 bears interest at
    13.6% per annum and requires equal monthly principal payments of $9,838
    beginning on September 28, 1997.
 
        The Company makes contributions to the Trust equal to the monthly
    payment of principal and interest on the ESOP loans as they become due.
    Because the payment of principal results in the release of shares from
    collateral, which shares are then available for allocation to employees, the
    principal portion of these contributions is recorded as compensation
    expense. Such contributions are, therefore, expensed to compensation and 
    interest when they are made or accrued. The compensation and interest 
    elements are as follows:
 


                                                                      SEPTEMBER 27,  SEPTEMBER 28,  SEPTEMBER 30,
FOR THE FISCAL YEARS ENDED:                                               1997           1996           1995

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

 
        At its August 27, 1997 meeting, the Board of Directors voted to
    terminate the Employee Stock Ownership Plan effective October 1, 1997.
 
        On May 31, 1995, the Company completed an asset purchase of the secure
    communications business of Datotek, Inc., a subsidiary of AT&T Corp., for
    $3,687,000 (see Note 15). This acquisition was funded partly by the
    Company's cash reserves and partly through loans amounting to $2,250,000
    from two banks. These loans, 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.
 
        At September 27, 1997, the Company had a $3,500,000 line of credit at a
    rate of prime plus 1/2 of 1%. Availability under the line of credit has been
    reduced by $839,158 for outstanding standby letters of credit (see Note 10).
    During June 1997, the Company borrowed $500,000 against its credit line,
    subsequently paying the amount back in full during August 1997 upon receipt
    of certain large trade receivables. Other than outstanding standby letters
    of credit, the Company had no borrowing under the line of credit in 1996 or
    1995.
 
        The foregoing bank loans and line of credit are secured by a pledge of
    substantially all the assets of the Company. This line of credit expires on
    May 1, 1998, unless renewed.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

        The valuation allowance relates to uncertainty with respect to the
    Company's ability to realize prepaid tax assets against future profits.
 
        Refundable income taxes represent estimated refunds from the Federal
    government from carryback claims. All refunds are expected to be received
    within the next fiscal year.
 
(7) STOCK OPTIONS
 
        At the February 1992 Annual Meeting of Stockholders, the Company adopted
    the Technical Communications Corporation 1991 Stock Option Plan (the SOP
    Plan) to replace a previous, expired plan. The Company reserved 250,000
    shares of common stock for issuance to employees at prices not less than the
    fair market value on the date of grant. At the February 1997 Annual Meeting
    of Stockholders, the Company increased the reserve for shares under the SOP
    Plan to 350,000. Options under this plan generally expire ten years from the
    date of grant and are exercisable in cumulative annual increments commencing
    one year after the date of grant.
 
        The Company had previously adopted an Incentive Stock Option Plan (the
    ISO Plan) which reserved shares of common stock for issuance to employees at
    prices not less than the fair market value on the date of grant. The ISO
    Plan expired December 15, 1991. Options are still outstanding, generally
    expire ten years from the date of grant, and are exercisable in cumulative
    annual increments commencing one year after the date of grant.

        In 1991, the stockholders approved a Non-Qualified Stock Option Plan
    which reserved 50,000 shares of common stock for issuance to non-employee
    Directors of the Company at prices not less than the fair market value on
    the date of grant. This plan was discontinued in February 1997, but options
    are still outstanding and are exercisable at any time after the date of the
    grant until expiration, which is five years from the date of grant.
 
        In October 1995, the Financial Accounting Standards Board issued
    Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
    Stock-Based Compensation," which sets forth a fair-value based method of
    recognizing stock-based compensation expense. As permitted by SFAS No. 123,
    the Company has elected to continue to apply Accounting Principles Board
    Opinion No. 25 to account for its stock-based compensation plans. Had
    compensation for awards in fiscal years 1995 through 1997 under the
    Company's stock-based compensation been determined based on the fair value
    at the grant dates consistent with the method set forth under SFAS No. 123,
    the effect on the Company's net income and earnings per share would have
    been as follows:



                                                                      SEPTEMBER 27,  SEPTEMBER 28,  SEPTEMBER 30,

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
        Because the method prescribed by SFAS No. 123 has not been applied to
    options granted prior to October 1, 1994, the resulting pro forma
    compensation expense may not be representative of the amount to be expensed
    in future years. Pro forma compensation expense for options granted is
    reflected over the vesting period; future pro forma compensation expense may
    be greater as additional options are granted.
 
        The fair value of each option granted was estimated on the grant date
    using the Black-Scholes option pricing model with the following weighted
    average assumptions: risk-free interest rates of 6.00%, 6.43%, and 6.00% for
    1997, 1996, and 1995, respectively, expected life equal to each grant's
    vesting period (1 to 9 years), expected volatility of 100%, and an expected
    dividend yield of 0%.

(8) PROFIT-SHARING PLAN
 
        The Company has a qualified, contributory, trusteed profit-sharing plan
    covering substantially all employees. The Company's policy is to fund
    contributions as they are accrued. The contributions are allocated based on
    the employee's proportionate share of total compensation.
 
        The Company's contributions to the plan are determined by the Board of
    Directors and are subject to other specified limitations. No provision for a
    contribution has been made for 1997. However, the Board of Directors, at its
    August 27, 1997 meeting approved a corporate match of 25 cents per dollar of
    the first 6% of each participant's contributions to the plan for fiscal
    1998. Provisions of approximately $46,000, and $40,000 were recorded in 1996
    and 1995, respectively, for the Company's contributions to the plan.
 
        The Company offers no post-retirement benefits as defined in the
    Statement of Financial Accounting Standards No. 106, "Employers' Accounting
    for Post-Retirement Benefits other than Pensions."
 
(9) EXECUTIVE INCENTIVE BONUS PLAN
 
        The Company has an Executive Incentive Bonus Plan for the benefit of key
    management employees. The bonus pool is determined based on the Company's
    performance as defined in the plan. In fiscal 1997 and 1995, no bonuses were
    earned. Bonuses of $104,500 accrued in fiscal 1996 for key management
    employees were dis-tributed during fiscal 1997.
 
(10) OFF-BALANCE SHEET RISK AND CONCENTRATION OF CREDIT RISK
 
        At September 27, 1997, and September 28, 1996, the Company was
    contingently liable under open standby letters of credit totaling $839,158
    and $66,910, respectively. These letters of credit are issued in the
    ordinary course of business to secure the Company's performance under
    contracts with its customers. These letters of credit expire as provided for
    in the contracts, unless exercised or renewed. To date, no letters of credit
    have been exercised. The Company does not expect to incur any loss
    associated with these letters of credit.

        As of September 27, 1997, management believes it has no significant
    concentrations of credit risk due to placement of its cash equivalents with
    high-credit-quality financial institutions, and the fact that the majority
    of its foreign trade receivables are secured by letters of credit or foreign
    credit insurance.
 
(11) RELATED PARTY TRANSACTIONS
 
        Herbert A. Lerner, Company Director and Treasurer, and James A.
    McCalmont, Director, are Trustees of the Technical Communications
    Corporation Employees' Stock Ownership Trust. At its August 27, 1997
    meeting, the Board of Directors voted to terminate the Employee Stock
    Ownership Plan effective October 1, 1997.
 
        Edward E. Hicks, Esq., the Company's Secretary and Clerk, is a member of
    a law firm that provides legal services to the Company.

        Lawrence A. Kletter, Esq., who resigned as a director during fiscal year
    1997, is a member of a law firm that provided legal services to the Company.
 
        Carl H. Guild, Jr., elected to the Board of Directors effective May 1,
    1997, serves as a consultant for the Company, earning $52,500 in this
    capacity during fiscal 1997.
 
        During fiscal years 1997 and 1996, the Company incurred expenses of
    $116,038 and $96,360, respectively, to FutureComms, Inc., a privately held
    telecommunications software consulting services company. FutureComms is
    owned and operated by Michelle D. Gerard, the wife of the Company's
    President and CEO. FutureComms' work ended on August 29, 1997.
 
        During 1996 and 1995, the Company leased a sales office from its
    Chairman; lease payments were $1.00 in each year. The fair market value of
    such rent was estimated to be below $5,000 per year.
 
        On June 27, 1995, the Company invested $250,800 for a minority interest
    in Series B Preferred Stock of Net2Net Corporation, a privately held company
    that develops high performance management and analysis systems for
    Asynchronous Transfer Mode (ATM) networks. The Company also paid a deposit
    for inventory, purchased at a discounted price, valued at $244,200 as well
    as entered into an eighteen month distribution agreement with Net2Net that
    gave the Company the exclusive right to sell Net2Net products to certain
    U.S. Government departments. As of September 27, 1997, $144,283 of the
    inventory has been sold and the remain-ing amount of $99,917 has been either
    written-down or fully reserved. Net2Net's president is Stephen McCalmont,
    son of Arnold McCalmont, and brother to James McCalmont. Arnold and James
    McCalmont, as well as Herbert Lerner, are also investors in Net2Net
    Corporation. This investment, which represents less than a 5% interest, has
    been accounted for using the cost method.
 
(12) COMMITMENTS AND CONTINGENCIES
 
        The Board of Directors has authorized payments of $30,000 per year for
    five years to the wife of the Chairman of the Board of Directors, provided
    that she survives him, in the event of his death at a time when he is
    employed by the Company. The Company carries insurance on the life of the
    Chairman sufficient to fund this contingent liability in full.
 
        The Company is party to various claims arising in the normal course of
    business. Management believes that these are adequately provided for or will
    result in no significant additional liability to the Company.

        On December 12, 1997, the Board of Directors announced that it has
    undertaken an internal review of certain of its historical service
    contracts. On January 13, 1998 the Company announced that the results 
    from its internal review concluded that certain of TCC's internal 
    approval and control procedures were not followed in connection with such 
    contracts. However, the Company does not believe that this will result in 
    a material liability or asset impairment to the Company or otherwise have 
    any material effect on the financial position or results of operations of 
    the Company.


 
(13) MAJOR CUSTOMERS AND EXPORT SALES
 
        In fiscal 1997, the Company had three customers representing 51% (25%,
    13%, and 13%) of net sales. In fiscal 1996, the Company had three customers,
    including the U.S. Government as one customer, representing 54% (26%, 16%,
    and 12%) of net sales. In fiscal 1995, the Company had three customers,
    including the U.S. Government, representing 57% (24%, 20%, and 13%) of net
    sales.

(14) LEASES
 
        The Company leases its headquarters under an operating lease.
 
        The Company has renewed the lease on its headquarters located in
    Concord, Massachusetts through June 30, 2000. Future minimum lease payments
    depend on the Consumer Price Index at December 31, 1997, but are estimated
    at $158,700 a year through fiscal 1999 and $119,000 for the first nine
    months of fiscal 2000. This lease may be further renewed for an additional
    two and one-half years through December 31, 2002. The Company also retains
    an option to purchase the building at fair market value, but not to exceed
    $2,262,000, exercisable at the end of the current renewal term, and of the
    additional renewal term, if elected. Annual rental expense amounted to
    $146,160 during fiscal years 1995 through 1997.
 
(15) ACQUISITION
 
        Effective May 31, 1995, the Company acquired substantially all of the
    assets of Datotek, Inc., a subsidiary of AT&T Corp. Total consideration paid
    by the Company was $3,687,000, plus acquisition and financing costs. The
    acquisition was financed by the Company's own capital and a loan from two
    banks. These bank loans were subsequently paid off in November 1996.
    Operations resulting from this acquisition are included in the accompanying
    consolidated financial statements from the date of acquisition. The 
    acquisition was accounted for as a purchase, and accordingly, an allocation 
    of purchase cost to the Company's assets and liabilities (accounts 
    receivable, inventory, fixed assets, accounts payable, and accruals) 
    was made to reflect fair values. The allocation resulted in
    unallocated excess purchase cost over net assets acquired (goodwill) of

                                    Page AR-20



             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

    $1,614,131, which is being amortized on a straight-line basis over 7 1/2
    years. The parties made an election under the Internal Revenue Code to treat
    the purchase and sale agreement as a purchase of assets and assumption of
    liabilities.
 
        On an unaudited pro forma basis, giving effect to the transaction as if
    it occurred as of October 1, 1994, net sales for fiscal 1995 would have been
    $11,605,000 with a net loss of $235,000 or $.19 per share.
 
        The pro forma net sales and net loss do not purport to represent what
    the Company's results of operations would have been if such transactions in
    fact had occurred on such date or at the beginning of the period indicated
    or to project the Company's financial position or results of operations for
    any future date or period.

(17) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
        The following methods and assumptions were used to estimate the fair
    value of each class of financial instrument for which it is practicable to
    estimate that value.
 
a.) Cash and Cash Equivalents--The carrying amount of these assets on the
    Company's Consolidated Balance Sheet approximates their fair value because
    of the short maturity of these instruments.
 
b.) Long-term Debt--The fair value of this long-term indebtedness approximates
    the carrying amount since the variable interest rate paid reflects fair
    value.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(18) RISKS
 
        The Company is exposed to a number of business risks. These include, but
    are not limited to, concentration of its business amongst a relatively small
    number of customers (see Note 13), technological change (which can cause
    obsolescence of the Company's products and inventories), actions of
    competitors (some of whom have access to considerably greater financial
    resources than the Company), cancellation of major contracts (either before
    or after award), variations in market demand, the loss of key personnel,
    etc. The Company attempts to protect itself in various ways against such
    risks, but its success cannot be guaranteed.

(19) FORWARD-LOOKING STATEMENTS
 
        The foregoing footnotes contain forward-looking statements, such as, but
    not by way of limitation, expectations of future debt service requirements,
    lease payments, etc. In addition, the financial statements contain estimates
    by management that also constitute forward-looking statements, including but
    not limited to depreciation rates, adequate levels of inventory, warranty
    and other reserves, current values of assets and liabilities, etc., that
    involve risks and uncertainties. Actual values and results may be materially
    different. In particular, the value of assets and the adequacy of reserves
    depend upon future events which cannot be foreseen at this time because they
    may be affected by changes in the needs of the Company's customers, the
    products and pricing offered by the Company's competitors, general economic
    conditions and other factors.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Technical Communications Corporation:
 
We have audited the accompanying consolidated balance sheets of Technical 
Communications Corporation (a Massachusetts corporation) and its subsidiaries 
as of September 27, 1997, and September 28, 1996, and the related 
consolidated statements of operations, cash flows, and stockholders' equity 
for the years ended September 27, 1997, September 28, 1996, and September 30, 
1995. These financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these financial 
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audits to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of Technical 
Communications Corporation and subsidiaries as of September 27, 1997 and 
September 28, 1996, and the results of their operations and their cash flows 
for the years ended September 27, 1997, September 28, 1996 and September 30, 
1995, in conformity with generally accepted accounting principles.
