NOTE 2. LONG-TERM DEBT
As of January 2, 1999, the Company had a $5,000,000 revolving line of credit 
at a rate of plus 1/2 of 1% with Wainwright Bank and Trust Company. This line 
of credit is secured by a pledge of substantially all the assets of the 
Company, requires no compensating balances, and is due to mature on May 1, 
1999. Under the terms of the line of credit agreement, the Company is 
required to comply with certain loan covenants. As of January 2, 1999 the 
Company is compliant with these covenants. Availability under the line of 
credit had been reduced by $988,430, as of January 2, 1999, as a result of 
standby letters of credit. No other borrowings are outstanding against the 
line.

NOTE 3. COMMITMENTS AND CONTINGENCIES

The Company is the defendant in GERARD V. TECHNICAL COMMUNICATIONS 
CORPORATION, ET AL., filed in the United States District Court for the 
District of Massachusetts in 1998. This case arises from disputes concerning 
the hiring and termination of Roland Gerard, former president of the Company. 
According to the Complaint, the Company violated federal securities laws in 
the hiring process for Mr. Gerard by making false statements about the 
Company which induced him to accept employment, the compensation for which 
included certain stock options. The Complaint also alleges breach of 
contract, wrongful termination, and civil conspiracy. At present, the 
Company's motion to dismiss is pending. Because of the early stage of the 
litigation, it is impossible to determine the ultimate outcome. The Company 
is determined to contest this suit vigorously.

NOTE 4. COMPREHENSIVE INCOME

During the first quarter of fiscal 1999 the company adopted Statement of 
Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive 
Income". SFAS 130 established standards for the reporting and display of 
comprehensive income and its components. In general, comprehensive income 
combines net income and "other comprehensive income", which represents 
unrealized gain on securities available for sale. During the first quarter of 
fiscal 1999 the company's comprehensive income totaled ($761,188).


          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. 

Net sales for the quarter ended January 2, 1999 and December 27, 1997, were 
$1,071,356 and $2,935,048, respectively. This decrease of 63% is attributed 
to variability in revenue recognition as a result of the timing of shipments 
and the receipt of anticipated orders.

Gross profit for the first quarter of fiscal 1999 was $689,806 as compared to 
gross profit of $1,363,962 for the same period of fiscal year 1998. This 
represented a 49% decrease in gross profit for the quarter. Gross profit 
expressed as a percentage of sales was 64% in the first quarter of fiscal 
1999 as compared to 46% for the same period in fiscal year 1998.

Selling, general and administrative expenses for the first quarter of fiscal 
1999 and 1998 were $1,495,672 and $1,327,142, respectively. This increase of 
13% was primarily attributable to approximately $475,000 in costs associated 
with the settlement of litigation. These increased costs were partially 
offset by a reduction of approximately $308,000 in commissions, travel 
related costs and service contracts, associated with the lower sales volume 
and a continued effort at general cost reductions.

Product development costs for the quarter ended January 2, 1999 were $539,662 
compared to $232,991 for the same period in fiscal 1998. This increase of 
132% was attributable to the continued commitment to new product development, 
particularly the Cipher X7000 series product line.

The Company incurred a net loss of $988,388 for the first quarter of fiscal 
1999 as compared to a net loss of $128,719 for the same period in fiscal 
1998. The decrease in profitability is primarily attributable to the decrease 
in gross profit and the increase in operating spending as described above.

YEAR 2000 COMPLIANCE UPDATE

Technical Communications Corporation has been actively addressing the Year 
2000 (Y2K) problem since April 1998. Generally speaking, the Y2K problem 
results from the use of two-digit, rather than four-digit date years in 
computer systems and software applications. Today, many systems rely on two (or
one) digits to represent the year portion of a date. For example, 1997 is 
usually stored as 97 (or 7). As a result, the year 2000, represented by 00 
(or 0), could be interpreted as 1900. This type of error could cause problems 
when systems display, calculate, store and print dates.

The Company understands the importance of identifying and solving the Y2K 
problem. As a supplier of mission-critical encryption products, the Company 
is committed to providing products that will function, without interruption, 
into the year 2000. In addition, Technical Communications Corporation is 
taking proactive steps to ensure that all critical systems, from both an 
internal and external perspective, are reviewed and, if necessary, corrected.

COMPANY'S STATE OF READINESS

Technical Communications Corporation has divided its Y2K efforts into three 
major areas: (i) products and customers, (ii) enterprise business systems and 
information technology and (iii) external systems and suppliers. The review 
of each area will consist of an inventory of potentially affected systems, 
an assessment of Y2K readiness and corrective action deployment. As 
indicated, the Company has been actively working on Y2K related issues for 
ten months, and is prioritizing its efforts based on how severe an effect a 
potential noncompliance would have on customer service and core business 
functions. It is anticipated that the entire Y2K initiative will be complete 
by June 1999. Product testing and internal/external system evaluations are 
now complete. To facilitate the plan, the Company has appointed a program 
manager to oversee all Y2K initiatives.

Technical Communications Corporation has tested all of its current products 
for Y2K problems. A product is deemed Y2K compliant if the product, when used 
in accordance with its associated documentation, is capable of processing, 
receiving, and/or providing data within or between the 20(th) and 21(st) 
centuries, provided that all other products used in conjunction with the 
product in question properly exchange date data with that product. It should 
be noted that certain TCC products deemed to be Y2K compliant may require a 
service update in order to achieve Y2K compliant status.

Although no assurances can be given, the Company believes that all current 
products are either Y2K compliant, or can be made Y2K compliant with minor 
adjustments or software upgrades. This product assessment has identified 
date-related issues with certain older products that TCC no longer 
manufactures or sells. It is the Company's intent to offer upgrades or 
alternative products where reasonably practicable. In some cases the Company 
sells encryption systems that interact with third party products or operate 
with computer systems not under the Company's control. There can be no 
assurances that such third party equipment will function correctly into the 
year 2000.

TCC's internal Y2K initiative includes a review of all computer hardware and 
software related systems including: internal LAN, product development tools, 
facility operations, interfaces with third parties via EDI links and desktop 
systems. The inventory and assessment phase of this review is approximately 
90% complete. The Company's enterprise information system, which includes 
manufacturing, financial accounting and sales administration is now Y2K 
compliant. Supporting systems will continue to be tested and evaluated. At 
this time, the Company does not anticipate that any internal system will 
create a substantive disruption in the Company's operation into the year 2000.

The Y2K external systems review process consists of identifying and 
contacting suppliers and service providers that are believed to be 
significant to the Company's business operations. The Company will access 
each supplier's Y2K readiness based on its formal response to a TCC Y2K 
status request. The Company intends to monitor the Y2K compliant process of 
key suppliers that either indicate they are not yet Y2K compliant or do not 
respond to the Company's requests. This process is ongoing and is expected to 
continue in 1999.

COSTS TO ADDRESS THE COMPANY'S YEAR 2000 ISSUES

As of January 2, 1999, the Company has incurred expenses related to the Y2K 
problem of approximately $35,000. The main portion of these costs relates to 
the evaluation and testing of products for Y2K compliance. The Company 
anticipates additional costs ranging from $35,000-$100,000 in order to 
complete the Y2K process and to upgrade a small number of older products 
currently still in use. The preceding numbers represent TCC's best estimate 
of remediation costs pertaining to Y2K issues. There can be no assurances 
that the Company will not encounter unexpected costs or delays in achieving 
year 2000 compliance.

RISKS OF THE COMPANY'S YEAR 2000 ISSUES

Based on current information, the Company believes that the year 2000 problem 
will not have a material adverse effect on the Company's overall business and 
financial condition. Since all current products are either Y2K compliant or 
can be made Y2K compliant, future sales of all such products do not 
represent a Y2K risk to the Company. Even though TCC is adopting a proactive 
strategy, there can be no assurances that Y2K problems will not have any 
impact on the business. Despite efforts to ensure that products will function 
correctly into the Y2K, The Company may see an increase in warranty and other 
claims, especially those related to older products or products that 
incorporate third party software or hardware. If any of the Company's 
material suppliers or service providers experience unforeseen Y2K issues, the 
Company's production, product development, and operations may also be 
materially adversely effected.

COMPANY'S CONTINGENCY PLAN

TCC is working diligently to minimize the risks associated with Y2K issues. 
The Company plans to dedicate appropriate resources to address all known Y2K 
related issues in an expeditious manner. In addition, the Company is prepared 
to take immediate action on unforeseen problems as they arise. Such action may 
include the use of alternative sources of supply to support manufacturing and 
product development.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 133, "Accounting for Derivative 
Instruments and Hedging Activities". The Statement establishes accounting and 
reporting standards requiring that every derivative instrument (including 
certain derivative instruments embedded in other contracts) be recorded in 
the balance sheet as either an asset or liability measured at its fair value. 
FAS No. 133 is effective for fiscal years beginning after June 15, 1999. 
Management does not expect the adoption of this statement to have a material 
impact on its financial condition or results of operations.

During the first quarter of fiscal 1999 the company adopted Statement of 
Financial Accounting Standards No. 131 (SFAS 131), "Disclosures About 
Segments of an Enterprise and Related Information''. SFAS 131 established 
standards for the way that public companies report information about 
operating segments in financial statements. This Statement supercedes 
Statement of Financial Accounting Standards No. 14, "Financial Reporting for 
Segments of a Business Enterprise", but retains the requirement to report 
information about major customers. The adoption of this Statement did not 
have a material effect on the Company's financial statements.

LIQUIDITY AND CAPITAL RESOURCES

Cash and short-term investments increased by $2,628,826 or 355% to $3,368,875 
as of January 2, 1999, from a balance of $740,049 at October 31, 1998. This 
increase was primarily due to the reduction of accounts receivable and 
partially offset by an increase in inventory and a reduction in current 
liabilities. The current ratio increased to 4.9:1 at January 2, 1999 compared 
to 2.5:1 as of October 3, 1998, primarily as a result of the cash received on 
accounts receivable during the quarter.

As of January 2, 1999, the Company had a $5,000,000 revolving line of credit 
at a rate of prime plus 1/2 of 1% with Wainwright Bank and Trust Company. 
This line of credit is secured by a pledge of substantially all the assets of 
the Company, requires no compensating balances, and is due to mature on May 
1, 1999. Under the terms of the line of credit agreement, the Company is 
required to comply with certain loan covenants. As of January 2, 1999 the 
Company is compliant with these covenants. Availability under the line of 
credit had been reduced by $988,430 as of January 2, 1999, as a result of 
standby letters of credit. No other borrowings are outstanding against the 
line. In the prior year during the three months ended December 27, 1997, the 
Company borrowed $1,000,000 under its line of credit.

Management anticipates no unusual capital expenditures during the remainder 
of fiscal 1999. Management is currently working to renew its existing line of 
credit, if it is unable to do so, its operations may be substantially 
adversely affected.

CORPORATION, ET AL., filed in United States Court for the District of 
Massachusetts in 1998. This case arises from disputes concerning the  hiring

induced him to accept employment, the compensation for which included certain 
stock options. The Complaint also alleges breach of contract, wrongful
