              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS



(1)      BASIS OF PRESENTATION:

         The accompanying unaudited interim consolidated financial statements
of American Technical Ceramics Corp. and Subsidiaries (the "Registrant")
reflect all adjustments (consisting of normal recurring accruals) which are, in
the opinion of management, necessary for a fair presentation of its
consolidated financial position as of September 30, 1998 and the results of its
operations for the three months ended September 30, 1998 and 1997. These
financial statements should be read in conjunction with the summary of
significant accounting policies and notes to consolidated financial statements
included in the Registrant's Annual Report to Stockholders for the year ended
June 30, 1998. Results for the three months ended September 30, 1998 are not
necessarily indicative of results which could be expected for the entire year.


(2)      SUPPLEMENTAL CASH FLOW INFORMATION:

         During the three months ended September 30, 1998, significant non-cash
activities included (i) the purchase of approximately $100,000 of inventory in
exchange for common shares issued from treasury, (ii) the issuance of treasury
stock to pay approximately $190,000 in accrued bonus expenses, and (iii) the
addition of property, plant and equipment through an increase in capital lease
obligations of approximately $105,000.


(3)      INVENTORIES:

         Inventories included in the accompanying consolidated financial
statements consist of the following:

(4)      EARNINGS PER SHARE:

         Statement of Financial Accounting Standards No. 128 Earnings Per Share
("SFAS No. 128") establishes new standards for computing and presenting
earnings per share ("EPS") and applies to all entities with publicly held
common stock. SFAS No. 128 replaces the presentation of primary EPS with a
presentation of basic EPS and requires a dual presentation of basic and diluted
EPS on the face of the income statement for all entities with complex capital
structures and requires a reconciliation of the numerators and denominators of
the basic and diluted EPS computations. The Registrant adopted SFAS No. 128,
effective December 31, 1997, and therefore has calculated current periods' EPS
in accordance with this new standard. Accordingly, all prior periods' EPS data
have been restated to furnish comparative information.

(5)      COMPREHENSIVE INCOME:

         Effective July 1, 1998, the Registrant has adopted Financial
Accounting Standards No. 130 ("SFAS No. 130"). SFAS No. 130 establishes
standards for reporting and display of comprehensive income and its components
in financial statements. The Registrant's total comprehensive income is as
follows:

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS


         The following discussion and analysis should be read in conjunction
with the consolidated financial statements, related notes and other information
included in this Quarterly Report on Form 10-Q.

         Statements in this Quarterly Report on Form 10-Q that are not
historical fact may constitute "forward-looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995. All such
forward-looking statements are subject to risks and uncertainties, including,
but not limited to, the impact of competitive products, product demand and
market acceptance risks, fluctuations in operating results and delays in
development of highly complex products and the other matters listed in the
Registrant's Annual Report on Form 10-K for the fiscal year ended June 30, 1998
under the caption "Cautionary Statements Regarding Forward-Looking Statements"
and in the Registrant's other filings with the Securities and Exchange
Commission. These risks could cause the Registrant's actual results for future
periods to differ materially from those expressed in any forward-looking
statements made by the Registrant.


RESULTS OF OPERATIONS
---------------------

Three Months Ended September 30, 1998
Compared with Three Months Ended September 30, 1997
---------------------------------------------------

         Net sales for the three months ended September 30, 1998 decreased 13%
to $8,639,000 as compared to net sales of $9,958,000 for the comparable quarter
in the prior fiscal year. The decline in net sales was principally due to the
continuing decline in demand for the Registrant's core capacitor products in
both foreign and domestic markets which began in the second half of the prior
fiscal year. The economic situation in Asia has had an adverse impact on many
of the Registrant's customers, both domestic and foreign, resulting in
reductions and delays in their orders of the Registrant's products. As noted
below, in response to the current slowdown, the Registrant has taken steps to
bring its cost in line with sales and to rationalize its manufacturing
processes, reduced its work force through attrition and selected reductions and
accelerated the development of new products.

         The backlog of unfilled orders was $9,417,000 at September 30, 1998,
compared to $7,560,000 at September 30, 1997 and $6,308,000 at June 30, 1998.
The large increase in backlog is due to orders for non-core products, much of
which is not scheduled for shipment until the second half of the current fiscal
year.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


RESULTS OF OPERATIONS
---------------------

         Gross margin for the three months ended September 30, 1998 was 28% of
net sales as compared to 40.7% for the comparable quarter in the prior fiscal
year. The lower gross margin reported in the first quarter as compared to the
comparable quarter in the prior fiscal year was due to lower average selling
prices for the Registrant's core products, raw material price increases,
particularly for palladium, lower sales volume and an increase in certain
inventory reserves. Price increases in the price of palladium were principally
due to the unavailability of new product shipments from Russia. The Registrant
anticipates that the price of palladium will remain volatile, with the
likelihood of further price increases in fiscal year 1999. Accordingly, the
Registrant expects that palladium price increases will continue to impact gross
margins at least through the remainder of the current fiscal year.

         The Registrant has taken concrete steps to reduce fixed costs and
improve manufacturing flexibility. In particular, the Registrant has realigned
production capabilities by transferring manufacture of most large size
multilayer capacitors to its New York facilities and has reduced its work force
through layoff and attrition by approximately 10% as compared to June 30, 1998.
The Registrant expects that these steps will have a favorable impact on gross
margin in subsequent quarters primarily as a result of the consequent decrease
in fixed costs.

         Selling, general and administrative expenses for the three months
ended September 30, 1998 increased 4% to $2,076,000 as compared to $1,998,000
in the comparable period in the prior fiscal year due to planned increases in
advertising and promotional activities.

         Research and development expenses for the three months ended September
30, 1998 increased 26% to $487,000 as compared to $388,000 in the comparable
period in the prior fiscal year. This increase was primarily the result of
increased salary and product development expense to support an increase in
research and development activities designed to accelerate the development of
new products.

         Primarily as a result of the foregoing, net loss for the three months
ended September 30, 1998 was $82,000, or $.02 per common share ($.02 per common
share assuming dilution), compared to net income of $1,044,000, or $.27 per
common share ($.26 per common share assuming dilution), for the comparable
period in the prior fiscal year.

         The Registrant's financial position at September 30, 1998 remains
strong as evidenced by working capital of $17,712,000 and stockholders' equity
of $30,802,000. The Registrant's current ratio at September 30, 1998 was 4.9:1
as compared to a current ratio of 3.9:1 at June 30, 1998. The Registrant's
quick ratio at September 30, 1998 was 2.4:1 as compared to a quick ratio of
2.2:1 at June 30, 1998.

         Cash and investments decreased by $1,831,000 to $6,545,000 at
September 30, 1998 from $8,376,000 at June 30, 1998, primarily as a result of
an increase in raw materials inventory and a decrease in accounts payable.
Accounts receivable decreased by $619,000 to $3,801,000 at September 30, 1998
from $4,420,000 at June 30, 1998. Inventories increased by $433,000 to
$11,317,000 at September 30, 1998 from $10,884,000 at June 30, 1998 due to
higher raw material costs (particularly for palladium) and a planned build up
of palladium inventory as a hedge against possible future adverse changes in
price and/or availability of this material. Accounts payable and accrued
expenses decreased by $1,481,000 to $3,160,000 at September 30, 1998 from
$4,641,000 at June 30, 1998, primarily as a result of year end accruals paid
during the first quarter. Income taxes paid in the three month period ended
September 30, 1998 were $79,320.

         In September 1996, the Registrant secured a $2,000,000 revolving
line-of-credit from Barnett Bank of Jacksonville, N.A. ("Barnett"). The
line-of-credit is subject to certain fees on the unused portion while the
outstanding balance bears interest at a rate equal to Barnett's prime rate
minus one-half percent (1/2%). Borrowings under the line-of-credit are subject
to, among other things, continued compliance with certain financial covenants,
including maintenance of asset and liability percentage ratios. There is
currently no balance outstanding under this line-of-credit.

         The Registrant is negotiating to renew the $2,000,000 revolving
line-of-credit with NationsBank, NA ("NationsBank"), the successor to Barnett,
and to secure a $3,500,000 line-of-credit with NationsBank for equipment
purchases. It is expected that both lines will bear interest at 2% above the
three month rate for U. S. Dollar deposits on the London Interbank Market.
Principal under the revolving line-of-credit will be repayable in eight
quarterly installments commencing upon expiration of the revolving period. The
outstanding principal under the equipment line-of-credit will be rolled over
every six months into a self amortizing term note of not less than four nor
more than seven years. The equipment loan will be secured by the equipment
purchases. Borrowing under both lines will be subject to compliance with
certain financial covenants. The Registrant expects to close on these
financings within the next 30 days, although unless and until definitive
documentation is negotiated and signed, there is no assurance that it will be
able to obtain such financings.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

         Capital expenditures for the three months ended September 30, 1998
totaled $698,000 of which $432,000 was for machinery and equipment. The
Registrant intends to use cash on hand and, if obtained, the new equipment loan
noted in the preceding paragraph to finance budgeted capital expenditures of
approximately $4,000,000 for the remainder of fiscal year 1999, primarily for
additions to and replacement of machinery and equipment.

         In June 1990, the Registrant announced its first stock purchase
program pursuant to which it is authorized to purchase up to $1,000,000 of its
Common Stock. As of September 30, 1998, the Registrant has expended the entire
amount. In September 1998, the Board of Directors authorized the purchase of up
to an additional $1,000,000 of the Registrant's common stock under its second
stock purchase program. As of September 30, 1998, the Registrant has expended
approximately $410,000 under the second program and has purchased on aggregate
of 395,000 shares under both programs.

YEAR 2000
---------

         The Registrant has completed the assessment phase of identifying
computer systems that could be affected by the "Year 2000" problem. The
Registrant is presently in the remediation phase of its efforts to deal with
the Year 2000 problem, and anticipates that this phase will be substantially
completed by January 1, 1999. The Registrant anticipates completion of the
testing phase in 1999. To date, the Registrant has not incurred significant
incremental expenditures related to its Year 2000 activities, nor does it
anticipate incurring significant additional expenditures through completion of
its efforts.

         The Registrant is also presently obtaining representations from its
key suppliers and customers relative to their efforts to deal with the Year
2000 problem. Based upon the representations obtained to date, the Registrant
does not anticipate significant additional expenditures or lost revenues from
failure of its key suppliers and customers.

         The Registrant's remediation strategy is primarily based upon recoding
existing systems software using internal resources, rather than the replacement
of these systems. As such, the Registrant believes that its primary risk
relates to the continued availability and timely allocation of internal
personnel involved in remediation efforts. As the Registrant's remediation and
testing efforts are substantially within its control, the Registrant's
contingency plans involve assuring adequacy of personnel.
