                    CONDITION AND RESULTS OF OPERATIONS
                      (In thousands except share data)

               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, changes in product mix, costs and availability of raw
materials, fluctuations in operating results and delays in development of highly
complex products, risks associated with international sales and sales to the U.
S. military, risk of customer contract or sales order cancellation and the other
matters listed in the Registrant's Annual Report on Form 10-K for the fiscal
year ended June 30, 1999 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 December 31, 1999 Compared with Three Months Ended December
31, 1998

               Net sales for the three months ended December 31, 1999 increased
75% to $14,893 from $8,504 in the comparable quarter in the prior fiscal year.
The increase in net sales was attributable to increases in all product areas
except domestic hi-rel products. The product areas demonstrating the highest
levels of growth were thin film and core domestic commercial capacitors. Sales
activity continued at similar rates during the first month of the third quarter.
Sales to a major telecommunications OEM accounted for 17% of the Registrant's
net sales in the three months ended December 31, 1999.

               The backlog of unfilled orders was $14,836 at December 31, 1999,
compared to $9,466 at December 31, 1998 and $11,210 at September 30, 1999. The
increase in backlog compared to both the comparable quarter in the prior fiscal
year and the immediately preceding quarter was due primarily to an approximately
$5.5 million dollar order received for thin film product.

               Gross margin for the three months ended December 31, 1999 was
42.5% of net sales as compared to 35.7% for the comparable period in the prior
fiscal year. The improvement in gross margin was due principally to the higher
sales volume, particularly in thin film products, and the resulting increases in
efficiency.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)
                        (In thousands except share data)


               In February 2000 the Registrant commenced purchasing palladium,
which is used in the manufacturing of the majority of the Registrant's
capacitors, after not having done so for approximately twelve months. Prevailing
market prices for palladium are significantly higher than prices the Registrant
paid for palladium held in inventory at December 31, 1999. At its current usage
rate, the Registrant expects that these higher prices may negatively impact
gross margins in the latter half of fiscal year 2001.

               Selling, general and administrative expenses for the three months
ended December 31, 1999 increased 53.1% to $3,035 as compared to $1,983 in the
comparable period in the prior fiscal year. The increase was due to increased
commission expense as a result of the increase in net sales, an increase in
bonus expense as a result of the increase in net income, a new executive
incentive plan and the expenses associated with the Registrant's sales office in
Stockholm, Sweden, which commenced operations in August 1999.

               Research and development expenses for the three months ended
December 31, 1999 increased 59.9% to $718 as compared to $449 in the comparable
period in the prior fiscal year. This increase was primarily the result of
increased personnel costs due to the creation of a dedicated Radio Frequency
design group. This group works with the Registrant's existing design and
marketing personnel in order to accelerate the development of new products and
increase the breadth of the Registrant's research and development activities.

               Primarily as a result of the foregoing, net income for the three
months ended December 31, 1999 was $1,659, or $.43 per common share ($.43 per
common share assuming dilution), compared to net income of $516, or $.13 per
common share ($.13 per common share assuming dilution), for the comparable
period in the prior fiscal year.

Six Months Ended December 31, 1999
Compared with Six Months Ended December 31, 1998

               Net sales for the six months ended December 31, 1999 increased
56% to $26,756 as compared to net sales of $17,143 for the comparable period in
the prior fiscal year. The increase in sales was primarily the result of an
increase in overall demand for thin film and core domestic commercial
capacitors.

               Gross margin for the six months ended December 31, 1999 was 38.6%
of net sales as compared to 31.8% for the comparable period in the prior fiscal
year. The improvement in gross margin was due to higher sales volume,
particularly in thin film products, and the resulting increases in efficiency.

                        (In thousands except share data)

               Selling, general and administrative expenses for the six months
ended December 31, 1999 increased 29% to $5,233 as compared to $4,059 in the
comparable period in the prior fiscal year. The increase was due to increased
commission expense as a result of the increase in net sales, an increase in
bonus expense as a result of increase in net income, a new executive incentive
plan and the expenses associated with the Registrant's sales office in
Stockholm, Sweden, which commenced operations in August 1999.

               Research and development expenses for the six months ended
December 31, 1999 increased 33.3% to $1,248 as compared to $936 in the
comparable period in the prior fiscal year. This increase was primarily the
result of increased personnel costs due to the creation of a dedicated Radio
Frequency design group and general increases in recruitment and relocation
expenses.

               As a result of the foregoing, net income amounted to $2,489, or
approximately $.65 per common share ($.64 per common share assuming dilution),
for the six months ended December 31, 1999 compared to net income of $434, or
approximately $.11 per common share ($.11 per common share assuming dilution),
for the comparable period in the prior fiscal year.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------
               The Registrant's financial position at December 31, 1999 remains
strong as evidenced by working capital of $20,564 and stockholders' equity of
$34,868. The Registrant's current ratio at December 31, 1999 was 3.4:1 as
compared to a current ratio of 4.5:1 at June 30, 1999. The Registrant's quick
ratio at December 31, 1999 was 1.9:1 compared to the quick ratio at June 30,
1999 of 2.2:1.

               Cash and investments increased by $1,795 to $7,822 at December
31, 1999 from $6,027 at June 30, 1999, primarily as a result of increased cash
flow from profitable operations. Accounts receivable increased by $2,119 to
$7,393 at December 31, 1999 from $5,274 at June 30, 1999 due to the higher level
of sales. Inventories increased by $228 to $12,664 at December 31, 1999 from
$12,436 at June 30, 1999. Accounts payable and accrued expenses increased by
$1,976 to $6,168 at December 31, 1999 from $4,192 at June 30, 1999, primarily as
a result of increased raw material purchases and increased bonus and commission
expense. No income tax payments were made in the three month period ended
December 31, 1999.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)
                        (In thousands except share data)

               In November 1998, the Registrant renewed a $2,000 revolving
line-of-credit with NationsBank, NA ("NationsBank"), the successor to Barnett
Bank of Jacksonville, N.A. ("Barnett Bank"), and secured a $3,500 line-of-credit
with NationsBank for equipment purchases. Both lines bear interest at 2% above
the three month rate for U. S. Dollar deposits on the London Interbank Market.
Principal balances 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
periodically into a self amortizing term note of not less than four nor more
than seven years. The equipment loan is secured by the related equipment
purchases. Borrowing under both lines is subject to compliance with certain
financial covenants, including maintenance of asset and liability percentage
ratios. As of December 31, 1999, the Registrant has borrowed an aggregate of
$797 under the equipment line.

               Capital expenditures for the six months ended December 31,1999
totaled $2,606 of which $1,946 was for machinery and equipment. The Registrant
intends to use cash on hand and its equipment line of credit to finance budgeted
capital expenditures of approximately $3,400 for the remainder of fiscal year
2000, primarily for additions to and replacement of machinery and equipment and
facility expansion.


YEAR 2000
---------
               The Registrant had previously completed all remediation and
testing of internal computer systems that it believed could have been affected
by the "Year 2000" problem, and as a result has not incurred any problems with
the "Year 2000" problem to date. The Registrant did not incur, nor does it
expect to incur, significant incremental expenditures related to its Year 2000
activities.
