              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.       CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

         The financial statements presented herein are based on interim amounts.
         In the opinion of management, all adjustments (consisting only of
         normal recurring accruals) necessary to present fairly the financial
         position, results of operations and cash flows at September 30, 2003
         and for all periods presented have been made. The income from
         operations for the quarter ended September 30, 2003 is not necessarily
         indicative of the operating results for the full year.

         Certain information and footnote disclosures normally included in
         financial statements prepared in accordance with accounting principles
         generally accepted in the United States of America have been condensed
         or omitted. It is suggested that these condensed consolidated financial
         statements be read in conjunction with the financial statements and
         notes thereto included in the Registrant's June 30, 2003, Annual Report
         on Form 10-K.

2.       EARNINGS PER COMMON SHARE

         Basic earnings per common share are computed based on the weighted
         average number of common shares outstanding. The weighted average
         number of common shares outstanding for the quarters ending September
         30, 2003 and 2002 were 3,766,093 and 3,855,625, respectively. When
         dilutive, stock options are included as share equivalents using the
         treasury stock method. Common stock equivalents of 139,928 and 185,071
         related to stock option grants were included in the computation of the
         average number of shares outstanding for diluted earnings per common
         share for the quarters ended September 30, 2003 and 2002, respectively.

4.       STOCK PURCHASE AGREEMENT

         The Company has an agreement with its Chairman to repurchase Company
         common stock from his estate in the event of his death. The repurchase
         price is 95% of the fair market value of the common stock on the date
         that notice to repurchase is provided to the Company. The total number
         of shares to be repurchased shall be sufficient to provide proceeds
         which are the lesser of $2,500,000 or the amount of estate taxes and
         administrative expenses incurred by his estate. The Company is
         obligated to pay in cash 25% of the total amount due and to execute a
         promissory note at the prime rate of interest for the balance. The
         Company maintains a $1,150,000 life insurance policy to fund a
         substantial portion of this obligation. At September 30, 2003 and June
         30, 2003, $1,490,000 has been classified as a Contingently Redeemable
         Equity Interest reflecting the estimated obligation in the event of
         execution of the agreement.

5.       RECENTLY ISSUED FINANCIAL ACCOUNTING PRONOUNCEMENTS

         During April 2003, the Financial Accounting Standards Board ("FASB")
         issued Statement of Accounting Standards ("SFAS") No. 149, "Amendment
         of Statement 133 on Derivative Instruments and Hedging Activities,"
         which amends and clarifies financial accounting and reporting for
         certain derivative instruments. We do not anticipate the adoption of
         this statement to have a material impact on our consolidated financial
         statements, as we are not currently a party to derivative financial
         instruments included in this standard.

         During May 2003, the FASB issued SFAS No. 150, "Accounting for Certain
         Financial Instruments with Characteristics of both Liabilities and
         Equity," which establishes standards for the classification and
         measurement of certain financial instruments with characteristics of
         both liabilities and equity. We do not anticipate the adoption of this
         statement to have a material impact on our consolidated financial
         statements, as we are not currently a party to such instruments
         included in this standard.

6.       DIVIDENDS DECLARED

         On September 29, 2003, the Company declared a quarterly cash dividend
         of $0.13 per share for stockholders of record on September 30, 2003 to
         be paid October 15, 2003. Such dividend payable has been recorded at
         September 30, 2003.

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

Financial Condition, Liquidity and Capital Resources

Cash provided by operating activities during the three months ended September
30, 2003 amounted to $1,084,676. This was a result of net income for the period
adjusted for changes in operating assets and liabilities, primarily related to
increases in accounts receivable, inventories, accounts payable and income taxes
payable.

Capital expenditures for new equipment (including production tooling) were
$37,681 for the quarter. Budgeted capital expenditures for fiscal year 2004 are
$1,573,000. The Company expects to generate sufficient funds through operations
to fund these expenditures.

Stockholders' investment decreased to $15,775,778 at September 30, 2003, from
$15,813,515 at June 30, 2003. The decrease reflects the effect of the exercise
of stock options, purchase and retirement of common stock, offset by net income
and dividends declared.

                                    7 of 17

The Company amended its existing credit facility in October 2003, extending the
maturity date of the unsecured line of credit to November 1, 2004. This credit
facility provides for borrowings up to a maximum of $10,000,000. The Company can
use this credit facility for working capital purposes or for the purchase of its
own common stock pursuant to the Company's common stock repurchase program.
Borrowings under this credit facility bear interest at the bank's prime rate, or
LIBOR plus 1.75%. This credit facility includes certain financial covenants that
require the Company to maintain a minimum tangible net worth and specified
current, interest coverage, and leverage ratios. The Company uses its credit
facility from time to time, although there was no utilization of this credit
facility at September 30, 2003 or June 30, 2003.

In April of 1995, the Board of Directors approved a stock repurchase program
authorizing the Company to purchase from time to time up to $2,000,000 of its
common stock for its own account. Subsequently, the Board of Directors
periodically have approved increases in the stock repurchase program. The most
recent increase was for an additional $2,000,000 in January 2003, for a maximum
of $37,500,000. The Company intends to effectuate all stock purchases either on
the open market or through privately negotiated transactions, and intends to
finance all stock purchases through its own cash flow or by borrowing for such
purchases.

For the quarter ended September 30, 2003, the Company purchased 45,000 shares of
its common stock at a net price of $13.59 per share, for a total net purchase
price of $611,325.

From the commencement of the Company's stock repurchase program through
September 30, 2003, the Company has purchased a total of 4,969,180 shares for a
total gross purchase price of $40,655,545, (representing an average gross
purchase price of $8.18 per share) and a total net purchase price of $36,030,060
(representing an average net purchase price of $7.25 per share). The difference
between the total gross purchase price and the total net purchase price is the
result of the Company purchasing from certain employees shares of the Company's
stock acquired by such employees pursuant to the Company's stock option program.
In determining the dollar amount available for additional purchases under the
stock repurchase program, the Company uses the total net purchase price paid by
the Company for all stock purchases, as authorized by the Board of Directors.

The Company also has an Employee Stock Ownership Plan and Trust ("ESOP")
pursuant to which shares of the Company's stock are purchased by the ESOP for
allocation to the accounts of ESOP participants. For the quarter ended September
30, 2003, the ESOP purchased 3,633 shares of the Company's stock.

Results of Operations

Net sales for the first quarter ended September 30, 2003 were $9,164,691
compared with $8,954,978 for the same period in 2002, an increase of $209,713.
The increase is primarily due to the contribution to sales by the acquired
Addax, now renamed BiAudio.

Gross profit as a percent of net sales decreased to 38% for the quarter ended
September 30, 2003 compared with 39% in the prior year, as a result of a lower
rate of overhead absorption.

Selling, general and administrative expenses for the quarter ended September 30,
2003 were $2,029,734 or 22% of net sales, compared to $1,880,652 or 21% of net
sales for the same period in 2002. This was due to the Company experiencing
higher sales commission for the quarter.

For the first quarter ended September 30, 2003, income from operations was
$1,467,911 versus $1,650,105 for the same period in the prior year.

Statement of Accounting Standards ("SFAS") No. 149, "Amendment of Statement 133
on Derivative Instruments and Hedging Activities," which amends and clarifies
financial accounting and reporting for certain derivative instruments. We do not

Instruments with Characteristics of both Liabilities and Equity," which
establishes standards for the classification and measurement of certain

not anticipate the adoption of this statement to have a material impact on our
consolidated financial statements, as we are not currently a party to such
instruments included in this standard.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

In management's opinion, the Company does not engage in any material risk
sensitive activities and does not have any market risk sensitive instruments,
other than the Company's commercial credit facility used for working capital
purposes and stock repurchases.
