              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.    CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

      The financial statements presented herein are based on interim figures
      and are subject to audit.  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
      March 31, 1997, and for all periods presented have been made.  The income
      from operations for the quarter and nine months ended March 31, 1997 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 generally accepted
      accounting principles 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, 1996, Annual Report on Form 10-K.

2.    EARNINGS PER COMMON AND COMMON EQUIVALENT SHARE

      Earnings per share are computed based on the average number of common and
      common share equivalents outstanding.  When dilutive, stock options are
      included as share equivalents using the Treasury stock method.  Common
      stock equivalents of 152,433 and 54,070 related to stock option grants
      were included in the computation of the average number of shares
      outstanding for the quarter ended March 31, 1997 and 1996, respectively.
      Common stock equivalent of 48,681 and 62,082 were outstanding for the
      nine months ended March 31, 1997 and 1996, respectively.

      The Financial Accounting Standards Board has issued Statement of
      Financial Accounting Standards No. 128, "Earnings per Share" (SFAS 128).
      SFAS 128 replaces primary EPS with basic EPS, which excludes dilution,
      and requires presentation of both basic and diluted EPS on the face of
      the income statement.  Diluted EPS is computed similarly to the current
      fully diluted EPS.  SFAS 128 is effective for financial statements issued
      for periods ending after December 15, 1997, and requires restatement of
      all prior-period EPS data presented.  The adoption of this statement is
      not expected to materially affect either future or prior-period EPS.

3.    INVENTORIES

      The classification of inventories is as follows:

4.    STOCK PURCHASE AGREEMENT

      The Company has an agreement with its Chairman to repurchase 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 a 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
      March 31, 1997 and June 30, 1996, $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.    DEFERRED COMPENSATION

      In 1991, the Board of Directors agreed to continue John C. Koss' current
      base salary in the event he becomes disabled prior to age 70.  After age
      70, Mr. Koss shall receive his current base salary for the remainder of
      his life, whether or not he becomes disabled.  The Company is currently
      recognizing an annual expense of $115,080 in connection with this
      agreement, which represents the present value of the anticipated future
      payments.  At March 31, 1997 and June 30, 1996, respectively, the related

                       KOSS CORPORATION AND SUBSIDIARIES
                           FORM 10-Q - March 31, 1997
 
                   MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Financial Condition and Liquidity

Cash used in operating activities during the nine months ended March 31, 1997
amounted to $802,572.  Working capital was $20,450,442 at March 31, 1997.  The
increase in working capital of $4,257,052 from the balance at June 30, 1996
reflects the net effect of an increase in inventory partially offset by
increased payables.  These increases are the result of anticipated higher sales
volume in the upcoming quarter.  The cash necessary to fund the Company's
operating activities fluctuates from time to time; however, as a general rule
the Company expects to generate adequate amounts of cash to meet future
operating needs.  The Company maintains sufficient borrowing capacity to fund
any shortfall.

Capital expenditures for new property and equipment (including production
tooling) were $672,002 for the nine months ended March 31, 1997.  Depreciation
and amortization aggregated $516,998 for the nine months.  For the fiscal year
ending June 30, 1997, the Company expects its capital expenditures to be
approximately $1,500,000.  The Company expects to generate sufficient operating
funds to fulfill these expenditures.

Stockholders' investment increased to $19,276,535 at March 31, 1997, from
$16,546,790 at June 30, 1996.  The increase reflects primarily the income for
the nine month period ending March 31, 1997.  No cash dividends have been paid
since the first quarter of fiscal 1984.

The Company has an unsecured working capital credit facility with a bank.  This
credit facility provides for borrowings up to a maximum of $8,000,000. 
Borrowings under this credit facility bear interest at the bank's prime rate,
or LIBOR plus 2.25%.  This credit facility includes certain covenants that
require the Company to maintain a minimum tangible net worth and specified
current, interest coverage, and leverage ratios.  Utilization of this credit
facility as of March 31, 1997 totaled   $2,160,567, consisting of $2,066,000 in
borrowings and $94,567 in commitments for foreign letters of credit. 
Utilization of this credit facility as of June 30, 1996 was $944,784,
consisting of $470,000 in borrowings and $474,784 in foreign letters of credit. 
The increase as of March 31, 1997 is the result of an increase in inventory due
to anticipated higher sales volume for the upcoming quarter. The Company can
also use up to $1,000,000 of its working capital credit facility to purchase
shares of its own stock.

The Company's Canadian  subsidiary has a line of credit of $550,000, which is
guaranteed by the Company.  Borrowings under this credit facility bear interest
at the bank's prime rate plus 1.5%.  The credit facility is subject to the
availability of qualifying receivables and inventories which serve as security
for the borrowings.  As of March 31, 1997 or June 30, 1996, there were no 
borrowings outstanding against this line of credit.  The due date for the line 
is October 31, 1997.

Pursuant to the Company's stock repurchase program, for the nine month period 
ended March 31, 1997, the Company purchased 51,629 shares of its common stock
at an average price of $6.83 per share.  All 51,629 shares were retired.  Since
the commencement of the Company's stock repurchase program, the Company has
purchased 343,576 shares of its common stock for a total of $2,125,014,
representing an average price of $6.18 per share.

For the nine month period ended March 31, 1997, the Company's Employee
Stock Ownership Plan and Trust ("ESOP") purchased 27,371 shares of the
Company's common stock for the ESOP at an average price of $8.38 per share. 
For the quarter ended March 31, 1997, the ESOP purchased 10,000 shares of the
Company's common stock for the ESOP at an average price of $11.18 per share.


Results of Operations

Net sales for the third quarter ended March 31, 1997 were $8,583,303 compared
to $8,482,620 for the same period in 1996.  Net sales for the nine months ended
March 31, 1997 were $31,766,272, up 14% compared with $27,941,603 during the
same nine months one year ago.  This increase was primarily a result of strong
orders throughout the period.

Gross profit as a percent of net sales was 34% for the quarter ended March 31,
1997 compared with 29% for the same period in the prior year.  For the nine
month period ended March 31, 1997, the gross profit percentage was 34% compared
with 30% for the same period in 1996.  Shifts in product mix resulted in the
increase in gross profit as compared to last year.

Selling, general and administrative expenses for the quarter ended March 31,
1997 were $2,169,313 or 25%, as against $2,160,599 or 25% for the same period
in 1996.  For the nine month period ended March 31, 1997, such expenses were
$6,660,273 or 21%, as against $6,529,139 or 23% for the same period in 1996.
The percentage decrease is a direct result of higher sales.

For the third quarter ended March 31, 1997, income from operations was $753,381
versus $303,880 for the same period in the prior year.  Income from operations
for the nine months ended March 31, 1997 was $4,094,214 as compared to
$1,962,033 for the same period in 1996.  The increase is primarily related to
higher sales and to the increase in gross margin resulting from shifts in
product mix.

Net interest expense amounted to $77,099 for the quarter as compared to $12,109
for the same period in the prior year.  For the nine month period, interest
expense amounted to $254,527 compared with $72,458 for the same period in the
prior year.  The increase is a result of the Company borrowing at much higher
levels as compared to the same periods last year.  The higher level of
borrowing was the result of increased inventory purchases to support the
increase in sales.

The Company recently agreed to an amendment and assignment of its License
Agreement with Trabelco N.V., covering North America, Central America, and 
South America, to Jiangsu Electronics Industries Limited, a subsidiary of
Orient Power Holdings Limited.  The assignment was effective as of March 31,
1997.  Orient Power has guaranteed Jiangsu's obligations under the License 
Agreement, as amended.   Orient Power is based in Hong Kong and has an extensive
portfolio of audio and video products. Pursuant to this assignment, Jiangsu has
agreed to make royalty payments through December 31, 2000, subject to certain 
minimum royalty amounts  due for the years 1998, 1999, and 2000. This license 
arrangement is subject to  renewal for additional 3 year periods. 

Royalty income earned in connection with this License Agreement for the quarter
ended March 31, 1997  was $212,244 as compared to $43,769 for the same period in
1996.  For the nine month period, royalty income was $908,619 compared to
$1,112,498 at March 31, 1996.  The Company recognizes royalty income when
earned.  The decrease in royalty income for the nine month period is the result
of lower sales volume by Trabelco N.V. in products covered under this License
Agreement.

The License Agreement with Trabelco N.V. covering many European countries
remains in place.  No sales have been reported under this License Agreement to
date; however, certain minimum royalties will be due for calendar years 1997
and 1998.  This License Agreement expires on December 31, 1998.  Trabelco N.V.
has the option to renew this License Agreement for additional 3 year periods.

             THIRD AMENDMENT AND ASSIGNMENT OF LICENSE AGREEMENT


        THIS THIRD AMENDMENT AND ASSIGNMENT ("Assignment") made and entered
into as of the 31st day of March, 1997, by and among TRABELCO, N.V., a

        WITNESSETH, THAT:

        WHEREAS, Assignee and Assignor, along with KEP and KCP (KEP, KCP and
Assignor are sometimes hereinafter referred to collectively as "Seller"), have
entered into a certain Asset Purchase Agreement dated as of March 31, 1997 (the
"Purchase Agreement"), pursuant to which Seller has agreed to sell and convey
and Assignee has agreed to purchase and acquire certain assets of Seller; and

        WHEREAS, the execution and delivery of this Assignment is a condition
precedent to the obligation of Assignee to consummate the transactions
contemplated by the Purchase Agreement; and

        WHEREAS, Assignor and Koss are parties to a certain License Agreement
dated November 15, 1991,
 as amended by Amendment to License Agreement dated
November 15, 1991, and a Second Amendment to License Agreement dated September
29, 1995 (as amended, the "License Agreement"); and

        WHEREAS, Assignor desires to assign and Assignee desires to accept such
assignment and assume all of Assignor's right, title and interest in and to and
obligations under said License Agreement; and

        WHEREAS, Koss, Assignor and Assignee desire to amend certain terms and
provisions of the License Agreement as hereinafter provided.

        NOW, THEREFORE, Assignor and Assignee have agreed that in exchange for
a payment being made to Assignor of Ten Dollars ($10.00) and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, Assignor and Assignee agree as follows:

        1.      Assignor hereby assigns to Assignee as of the Closing Date (as
defined in the Purchase Agreement) all of its right, title and interest in and
to and obligations under the License Agreement, a copy of which is attached
hereto as Exhibit A.

        2.      Assignor warrants that it is the Licensee under the License
Agreement; that the License Agreement is in full force and effect without
modification or amendment, except as hereinabove referenced; that no default
exists to the knowledge of Assignor,

<PAGE>   2
and no fact, circumstance or condition exists, to the knowledge of Assignor,
that with the passage of time or notice, or both, would constitute a default
under the License Agreement; and that, subject to the consent of Koss, it has
full right, power and authority to freely assign its interest under the License
Agreement pursuant to this Assignment. Assignor further warrants that its
interest under the License Agreement is free and clear of any and all liens and
encumbrances and that Assignee acquires Assignor's rights as Licensee under the
License Agreement subject only to, and as limited by the terms hereof, the
obligations of Assignee to perform the obligations of Licensee under the
License Agreement. Each of the warranties contained in this Section 2 are true
and correct on the date hereof and shall be true and correct on the Closing
Date (as defined in the Purchase Agreement).

          3.  Assignee, by acceptance of this Assignment, and as limited by the
terms hereof, assumes as of the Closing Date (as defined in the Purchase
Agreement) all of the rights, duties, obligations and covenants of Assignor
under the License Agreement. Notwithstanding the foregoing, Assignor shall
remain liable for the Minimum Royalty under the License Agreement for 1997.
Assignor shall make payment to Koss of such 1997 Minimum Royalty on the Closing
Date or immediately thereafter, but in no event later than May 9, 1997. Assignee
shall make payment of all Royalties during 1997 to Assignor until Assignor has
received all amounts paid to Koss representing the 1997 Minimum Royalty.
Thereafter, Royalties shall be paid to Koss in accordance with the terms of the
License Agreement.

          4.  No royalties will be payable to Koss with respect to any sales of
Licensed Products by Seller to Assignee.

          5.  For purposes of calculating the Royalties payable by Assignee to
Koss pursuant to Section 7 of the License Agreement, "net sales" shall be
determined based upon (i) Assignee's gross sales of each category of the
Licensed Products, less (ii) returned goods of each category of the Licensed
Products received by Assignor and its affiliate, Hagemeyer Service Center, Inc.
during 1997 and thereafter by Assignee.

          6.  Seller, to the extent of their rights as licensee or sub-licensee,
may continue to sell Licensed Products only in  connection with (a) the sale of
new Licensed Products which were pledged to KEP as collateral under a Line of
Credit Agreement dated May 6, 1997, and foreclosed by KEP after default by
Assignee, and (b) the sale (without warranty) of "as is" Licensed Products
returned to Seller through December 31, 1997 and repaired prior to May 1, 1998.
All sales of Licensed Products pursuant to subsection (a) shall be made only in
the Territory and shall be made pursuant to normal distribution channels for
such new Licensed Products. Seller shall have no right to continue sales
pursuant to subsections (a) and (b) hereof after December 31, 1998. All sales of
Licensed Products pursuant to subsection (b) hereof
  

                                       2

<PAGE>   3
shall be made only in the Territory and in markets and by use of distribution
channels other than these used by Assignor and/or Assignee to sell new Licensed
Products.  In the event of any sales of Licensed Products by Seller pursuant to
this Section 6, Seller shall pay to Koss Royalties with respect to Seller's
sales of Licensed Products in the Territory.  All Royalties paid by Seller
after the Effective Date (as defined in the Purchase Agreement) for any such
sales through December 31, 1997, shall be applied toward the Minimum Royalty
due under the License Agreement for 1997.  Notwithstanding Section 13.3 of the
License Agreement, in the event Licensor terminates the License Agreement due
to Assignee's default under the terms of this License Agreement, Koss shall
have the right to immediately negotiate and implement a new license with any
other third party for the Licensed Products and/or sell the Licensed Products
itself.

     7.   Seller and their affiliate, Hagemeyer Service Center, Inc., to the
extent of their rights as licensee or sub-licensee, may continue to use the
trade name "Koss Electronic Products" only in connection with (a) the collection
of accounts receivable arising from sales before March 31, 1997, (b) the
receipt of returned goods and the servicing of warranty repair claims as
provided herein, and (c) sales pursuant to Section 6 hereof.  In no event shall
Seller or any of its affiliates have the right to use the tradename "Koss
Electronic Products" after December 31, 1998.

     8.   Without limiting any other provision of this Assignment, Assignor
shall remain liable (a) for the payment of Royalties with regard to the sale of
new Licensed Products pursuant to subsection (a) of Section 6 above and (b) for
all obligations of Assignor pursuant to the License Agreement which arose prior
to the Closing Date (as defined in the Purchase Agreement).

     9.   Koss acknowledges the value of this agreement and the adequacy and
sufficiency of the consideration received, and hereby consents to the terms of
this Assignment and agrees that the License Agreement shall remain in full force
and effect and that following this Assignment Koss will continue to act as
licensor pursuant to the terms of the License Agreement as amended herein with
Assignee as licensee thereunder.

     10.  Other than as set forth herein, Assignor shall have no liability with
regard to Royalties pursuant to the License Agreement.  Koss and Assignee
hereby agree that Assignee shall pay to Koss the following Minimum Royalties
for the Contract Years set forth below:

                Year                    Minimum Royalties
                ----                    -----------------

        11.     Assignee shall have the right to grant a sublicense under the
License Agreement pursuant to Section 2.3 of the License Agreement as amended
by Section 16(b) hereof.

        12.     After payment to Koss of the Minimum Royalty for 1997, Seller
shall have no obligation to make any additional payment required to renew the
License Agreement upon the expiration of the current term and the parties
acknowledge that the payment by Seller of 1997 Minimum Royalty, as provided in
Section 3 hereof, satisfies Assignee's renewal obligation pursuant to the
License Agreement.

        13.     Assignee's affiliates, J.S. International, Inc. and Jiangsu
International Limited, shall have the right to use the tradename "Koss Audio &
Video Electronics" in connection with the manufacture, promotion, distribution
and sale of Licensed Products, the collection of related accounts receivable,
the receipt of related returned goods and the servicing of related warranty
repair claims.

        14.     After the Closing Date (as defined in the Purchase Agreement),
the liability of Assignor pursuant to the terms of the License Agreement and
the liability of HENA under its Guaranty attached to the License Agreement
shall continue in full force and effect as to all occurrences and events prior
