the meaning of Section 27A of the Securities Act of 1933, as amended. The
Company's operating results may differ significantly from the results
indicated by such forward-looking statements. The Company's operating results
may be affected by many factors, including but not limited to future changes

feasibility and market acceptance of new products, changes in

National Market System, no assurances can be given that the Company will
continue to be in compliance with all listing requirements or that the

NOTE 2.           DEBT

As of July 3, 1999, the Company has 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 matures on May 1, 2000. Under
the terms of the line of credit agreement, the Company is required to comply
with certain loan covenants. As of July 3, 1999, the Company is compliant
with these covenants. Availability under the line of credit has been reduced
by approximately $100,000, as of July 3, 1999, as a result of standby letters
of credit. No other borrowings are outstanding against the line. In the prior
year during the nine months ended June 27, 1998, the Company borrowed
$2,750,000 under its line of credit.

On April 30, 1999, the above mentioned line of credit was renewed. An
additional covenant was added, which restricts the amount of borrowings to a
percentage of certain accounts receivable and inventory balances. Management
believes this arrangement, in combination with its existing cash balances and
cash generated from operations, will be adequate to meet its liquidity and
capital requirements for the foreseeable future.

NOTE 3.      COMMITMENTS AND CONTINGENCIES

The Company is the defendant in GERARD v. TECHNICAL COMMUNICATIONS
CORPORATION, ET AL., filed in the Superior Court of the Commonwealth of
Massachusetts in 1999. This case arises from disputes concerning the hiring
and termination of Roland Gerard, former president of the Company. The
Complaint alleges state law claims for breach of contract, wrongful
termination, and civil conspiracy. The Company intends to file a motion to
dismiss in the near future. 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. An earlier complaint brought by Mr. Gerard in
the Federal court, which included the state claims, and a federal securities
claim was dismissed in July 1999; the securities claims were dismissed with
prejudice.

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 nine months and
quarter ended July 3, 1999 the Company's comprehensive loss totaled
$1,810,804 and $602,085, respectively.

NOTE 5.       SALE OF INVESTMENT IN VISUAL NETWORK, INC. COMMON STOCK

On April 1, 1999 the Company sold the majority of shares of its investment in
Visual Network, Inc. common stock. The Company recognized a gain on the sale
of $1,056,638 on a cost basis of $231,995. On July 9, 1999 and July 16, 1999,
the Company sold the remaining shares of its investment in Visual Network,
Inc. common stock. The Company will recognize a gain on the sale of $94,534
on a cost basis of $18,801, during the fourth quarter of 1999.

            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.

    QUARTER ENDED JULY 3, 1999 AS COMPARED TO QUARTER ENDED JUNE 27, 1998

Net sales for the quarters ended July 3, 1999 and June 27, 1998, were
$1,362,000 and $3,281,000, respectively. This decrease of 59% is attributed
to variability in revenue recognition as a result of the timing of shipments
as well as delays in the receipt of anticipated orders.

Gross profit for the third quarter of fiscal 1999 was $671,000 as compared to
gross profit of $2,124,000 for the same period of fiscal year 1998. This
represented a 68% decrease in gross profit for the quarter. Gross profit
expressed as a percentage of sales was 49% in 1999 as compared to 65% for the
same period in fiscal year 1998. The disparity between the two fiscal years
is attributed to the sale of a less favorable mix of lower margin products
during 1999.

Selling, general and administrative expenses for the third quarter of fiscal
1999 and 1998 were $1,044,000 and $1,385,0000, respectively. This decrease of
25% was primarily attributable to a decrease of $253,000 in payroll and
travel related costs and commissions and contract services support,
associated with the lower sales volume and the continued emphasis on expense
controls. In addition, there was a decrease in professional service fees of
$147,000. These decreased costs were partially offset by an increase of
$89,000 in product demonstration costs.

Product development costs for the quarter ended July 3, 1999 were $454,000
compared to $378,000 for the same period in fiscal 1998. This increase of 20%
was attributable to the continued commitment to new product development,
particularly the Cipher X 7000 series product line.

As a result of the Company's increase in cash available for investment and no
borrowings on its line of credit, net interest income increased from a net
expense of $62,000 during the third quarter of fiscal 1998 to a net income
position of $38,000 for the same period in the current year.

The Company incurred a net loss of $594,000 for the third quarter of fiscal
1999 as compared to net income of $222,000 for the same period in fiscal
1998. Included in the net loss for the third quarter of fiscal 1999 is a loss
from operations of $827,000. The decrease in operating profitability is
primarily attributable to the decrease in gross profit as described above.

  NINE MONTHS ENDED JULY 3, 1999 AS COMPARED TO NINE MONTHS ENDED JUNE 27, 1998

Net sales for the nine months ended July 3, 1999 and June 27, 1998, were
$3,680,000 and $9,622,000, respectively. This decrease of 62% in net sales is
attributed to variability in revenue recognition as a result of the timing of
shipments as well as delays in the receipt of some anticipated orders.

Gross profit for the nine months ended July 3, 1999 was $2,082,000, as
compared to gross profit of $5,598,000 for the same period of fiscal year
1998. This represented a 63% decrease in gross profit for the period. Gross
profit expressed as a percentage of sales was 57% in 1999 as compared to 58%
for the same


                                     Page 7



<PAGE>

period in fiscal year 1998. The disparity between the two fiscal years is
attributed to the sale of a less favorable mix of lower margin products
during 1999.

Operating expenses for the first nine months of fiscal 1999 were $3,605,000
and the first nine months of fiscal 1998 operating expenses were $4,257,000.
This decrease of 15% was primarily attributable to a decrease of $952,000 in
payroll and travel related costs and commissions and contract services
support, associated with the lower sales volume and the continued emphasis on
expense controls. In addition, there was a decrease in professional services
fees of $421,000. These decreased costs were offset by $475,000 in costs
associated with the settlement of litigation and an increase in promotional
and advertising expenses associated with new product introductions of $84,000
and $89,000 in product demonstration costs.

Product development costs for the nine months ended July 3, 1999 were
$1,546,000 compared to $912,000 for the same period in fiscal 1998. This
increase of 70% was attributable to the continued commitment to new product
development, particularly the Cipher X 7000 series product line.

As a result of the Company's increase in cash available for investment and no
borrowings on its line of credit, net interest income increased from a net
expense of $76,000 during the first nine months of fiscal 1998 to a net
income position of $110,000 for the same period in the current year.

The Company incurred a net loss of $1,435,000 for the first nine months of
fiscal 1999 as compared to net income of $272,000 for the same period in
fiscal 1998. Included in the net loss for the first nine months of fiscal
1999 is a one-time gain on the sale of an investment of $1,057,000 and a loss
from operations of $3,069,000. The decrease in profitability is primarily
attributable to the decrease in gross profit 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 fifteen months. As
of July 3, 1999, the Company has completed all of its Y2K efforts in the areas
described above with two minor exceptions involving our internal systems.

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 might require a
service update in order to achieve Y2K compliant status.


                                    Page 8


<PAGE>

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 the Company 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.

The Company'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. As of July 3, 1999 all internal systems have been
reviewed and evaluated. Except for the two minor items noted above, all
internal systems are now Y2K compliant. The remaining items will be upgraded
within the next 60 days. The Company's enterprise information system, which
includes manufacturing, financial accounting and sales administration, is
year 2000 compliant. 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 has reviewed
each key supplier and service provider's Y2K readiness based on its formal
response to a TCC Y2K status request. As a result the Company does not
foresee any disruption in the flow of goods and services. This process is
ongoing and is expected to continue into the year 2000.

COSTS TO ADDRESS THE COMPANY'S YEAR 2000 ISSUES
As of July 3, 1999, the Company has incurred expenses related to the year
2000 problem of approximately $58,000. The main portion of these costs
relates to the evaluation and testing of products for Y2K compliance. The
Company anticipates additional costs of approximately $5,000 in order to
complete the Y2K process. 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 year 2000 problems will not have any impact
on the business. Despite efforts to ensure that products will function
correctly into the year 2000, 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, including potential catastrophic failures due to loss of
electricity, security systems, heating systems, etc. Such action may include
the use of alternative sources of supply to support manufacturing and product
development.

RECENT ACCOUNTING PRONOUNCEMENT

In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 133 (SFAS 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


                                     Page 9

<PAGE>

on its financial condition or results of operations. In June 1999 FASB issued
Statement of Financial Accounting Standards No. 137 (SFAS 137), "Accounting
for Derivative Instruments and Hedging Activities--Deferral of the Effective
Date of FASB Statement No. 133--an amendment of FASB Statement No. 133". This
Statement has delayed the effective date of SFAS 133 until fiscal years
beginning after June 15, 2000.

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. SFAS 131 is a disclosure related statement
and has no financial impact on the company. The Company currently has only
one segment and no additional disclosures are required.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents increased by $2,522,000 or 341% to $3,262,000 as of
July 3, 1999, from a balance of $740,000 at October 3, 1998. This increase
was primarily due to the proceeds from the sale of the investment in Visual
Networks, Inc. and the reduction of accounts receivable, which were partially
offset by operating losses, an increase in inventory, paying down the line of
credit and a reduction in current liabilities. The current ratio increased to
6.5:1 at July 3, 1999 compared to 2.5:1 as of October 3, 1998, primarily as a
result of the cash received on accounts receivable during the period.

As of July 3, 1999, the Company has 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 matures on May 1, 2000. Under
the terms of the line of credit agreement, the Company is required to comply
with certain loan covenants. As of July 3, 1999, the Company is compliant
with these covenants. Availability under the line of credit has been reduced
by approximately $100,000, as of July 3, 1999, as a result of standby letters
of credit. No other borrowings are outstanding against the line. In the prior
year during the nine months ended June 27, 1998, the Company borrowed
$2,750,000 under its line of credit.

On April 30, 1999, the above mentioned line of credit was renewed. An
additional covenant was added, which restricts the amount of borrowings to a
percentage of certain accounts receivable and inventory balances. Management
believes this arrangement, in combination with its existing cash balances and
cash generated from operations, will be adequate to meet its liquidity and
capital requirements for the foreseeable future.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to market risk from changes in equity prices, which
could affect its future results of operations and financial condition. The
Company's long-term available-for-sale investment, in Visual Networks, Inc.,
represents a publicly traded equity security that is sensitive to
fluctuations in price. Changes in equity prices would result in changes in
the fair value of the Company's long-term available-for-sale investment due
to the difference between the current market price and the market price at
the last balance sheet date. Market risk has been significantly reduced by
the sale of most of the Company's investment in the security. A 10% decrease
in the market equity prices of July 3, 1999 would not have a material impact
on the book value of the Company's stockholders' equity.
