              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS



(1) PRINCIPLES OF CONSOLIDATION:

         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 March 31, 1998 and the results of its
operations for the quarter and nine months ended March 31, 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, 1997. Results for the nine months ended March 31, 1998 are not
necessarily indicative of results which could be expected for the entire year.


(2) INVENTORIES:

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

(3) 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. This

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Statement is effective for financial statements issued for periods ending after
December 15, 1997. The Registrant has adopted SFAS No. 128 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.

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, 1997
under 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 March 31, 1998
Compared with Three Months Ended March 31, 1997
-----------------------------------------------

         Net sales for the three months ended March 31, 1998 increased 4% to
$9,924,000 as compared to net sales of $9,541,000 for the comparable quarter in
the prior fiscal year. This increase was primarily attributable to increases in
domestic sales of commercial capacitors and in sales of Thin Film products
worldwide, while sales of capacitors into the commercial foreign market and
hi-rel products remained at comparable levels. The Registrant experienced a
slowing of marketplace activity in the third quarter of the current fiscal year
relative to the previous two quarters which was attributable at least in part
to the "current situation in Asia". Order bookings continued through April at
rates similar to those experienced in the third quarter. Based upon order
bookings to date, the Registrant expects revenues for the fourth quarter of the
current fiscal year to be below the comparable quarter of the prior fiscal
year. The backlog of unfilled orders was $7,131,000 at March 31, 1998, compared
to $7,618,000 at March 31, 1997 and $7,721,000 at June 30, 1997.

         Gross margin for the three months ended March 31, 1998 was 38.4% of
net sales as compared to 40.4% for the comparable quarter in the prior fiscal
year. The lower gross margin reported for the third quarter as compared to the
comparable quarter in the prior fiscal year was due to increases in

prices.

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

RESULTS OF OPERATIONS, continued
--------------------------------

         Total operating expenses for the three months ended March 31, 1998
increased 23% to $2,624,000 as compared to $2,129,000 in the comparable period
in the prior fiscal year. Selling, general and administrative expenses for the
three months ended March 31, 1998 increased 20% to $2,183,000 as compared to
$1,820,000 in the comparable period in the prior fiscal year. The increase in
selling, general and administrative expenses was due to increases in sales and
administrative personnel and increases in advertising and promotional
activities.

         Research and development expenses for the three months ended March 31,
1998 increased 43% to $441,000 as compared to $309,000 in the comparable period
in the prior fiscal year. The increase in research and development expenses was
primarily the result of higher salary expense due to an increase in research
and development personnel. The Registrant expects that expenditures for
research and development will continue at least at current levels throughout
the remainder of the current fiscal year.

         As a result of the foregoing, net income for the three months ended
March 31, 1998 was $792,000, or $.20 per common share ($.20 per common share
assuming dilution), compared to net income of $1,147,000, or $.29 per common
share ($.29 per common share assuming dilution), for the comparable period in
the prior fiscal year.


Nine Months Ended March 31, 1998
Compared with Nine Months Ended March 31, 1997
----------------------------------------------

         Net sales for the nine months ended March 31, 1998 increased 16% to
$30,703,000 as compared to net sales of $26,467,000 for the comparable period
in the prior fiscal year. The increase in sales was primarily the result of a
significant increase in demand during the first and second quarters for
commercial products in both domestic and foreign markets.

         Gross margin for the nine months ended March 31, 1998 was 42% of net
sales as compared to 37% for the comparable period in the prior fiscal year.
The higher gross margin in the current period was primarily attributable to
production efficiencies afforded by higher sales levels during the first and
second fiscal quarters and the full effects of process improvements which had
not yet been fully implemented during the nine months ended March 31, 1997.

RESULTS OF OPERATIONS, continued
--------------------------------

         Total operating expenses for the nine months ended March 31, 1998
increased 24% to $7,681,000 as compared to $6,204,000 in the comparable period
in the prior fiscal year. Selling, general administrative expenses for the nine
months ended March 31, 1998 increased 23% to $6,410,000 as compared to
$5,197,000 in the comparable period in the prior fiscal year, primarily as a
result of the higher levels of sales and increases in staff. Increased selling
expenses included higher salary expense, primarily as a result of increases in
sales personnel, higher commissions to representatives and expenses relating to
advertising and promotion activities. The increase in general and
administrative expenses is attributable to increases in personnel, higher
professional fees and increased bonus accruals due to higher pretax profits.

         Research and development expenses for the nine months ended March 31,
1998 increased 26% to $1,271,000 as compared to $1,007,000 in the comparable
period in the prior fiscal year. The increase in research and development
expenses was primarily the result of higher salary expense due to an increase
in research and development personnel and higher expenses for supplies to
support the increased research and development activity.

         As a result of the foregoing, net income amounted to $3,353,000, or
approximately $.86 per common share ($.83 per common share assuming dilution),
for the nine months ended March 31, 1998 compared to net income of $2,199,000,
or approximately $.57 per common share ($.56 per common share assuming
dilution), for the comparable period in the prior fiscal year.

LIQUIDITY AND CAPITAL RESOURCES, continued
------------------------------------------

         Cash and investments increased by $2,690,000 to $9,647,000 at March
31, 1998 from $6,957,000 at June 30, 1997, primarily as a result of the net
income for the nine months ended March 31, 1998. Accounts receivable decreased
by $147,000 to $4,373,000 at March 31, 1998 from $4,520,000 at June 30, 1997.
Inventories increased by $382,000 to $9,409,000 at March 31, 1998 from
$9,027,000 at June 30, 1997. Accounts payable and accrued expenses increased by
$670,000 to $4,365,000 at March 31, 1998 from $3,695,000 at June 30, 1997,
primarily as a result of increased expenses related to the higher levels of
sales. Income taxes paid in the nine month period ended March 31, 1998 were
$1,616,000.

         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.

          Capital expenditures for the nine months ended March 31, 1998 totaled
$2,455,000 of which $1,498,000 was for machinery and equipment. The Registrant
intends to use cash on hand and funds generated from operations to finance
budgeted capital expenditures of approximately $550,000 for the remainder of
fiscal year 1998, primarily for additions to and replacement of machinery and
equipment.

         In June 1990, the Registrant announced a stock purchase program
pursuant to which it is authorized to purchase up to $1,000,000 of its Common
Stock. As of March 31, 1998, the Registrant has expended approximately $805,000
to purchase an aggregate of 308,400 shares under this program.
