1. Basis of Presentation

    The accompanying unaudited consolidated financial statements have been
    prepared in accordance with generally accepted accounting principles for
    interim financial information and with the instructions to Form 10-Q and
    Article 10 of Regulation S-X. Accordingly, they do not include all of the
    information and footnotes required by generally accepted accounting
    principles for complete financial statements. In the opinion of the
    management, all adjustments (consisting of normal recurring accruals)
    considered necessary for a fair presentation have been included. Operating
    results for the three month period ended September 30, 2001 are not
    necessarily indicative of the results that may be expected for the year
    ending June 30, 2002.

    The balance sheet at June 30, 2001 has been derived from the audited
    financial statements at that date, but does not include all of the
    information and footnotes required by generally accepted accounting
    principles for complete financial statements. For further information, refer
    to the consolidated financial statements and footnotes thereto included in
    the Company's annual report on Form 10-K for the year ended June 30, 2001.

2. Litigation Settlement

    The Company, Medical Device Alliance, Inc. ("MDA") and MDA's wholly-owned
    subsidiary, Lysonix, Inc. ("Lysonix"), were defendants in an action alleging
    patent infringement filed by Mentor Corporation ("Mentor"). On June 10,
    1999, the United States District Court, central District of California,
    found for the defendants that there was no infringement upon Mentor's
    patent. Mentor subsequently filed an appeal. The issue concerned whether
    Mentor's patent is enforceable against the Company and does not govern
    whether the Company's patent in reference is invalid. On April 11, 2001, the
    United States Court of Appeals for the Federal Circuit Court issued a
    decision reversing in large part the decision of the trial court and
    granting the motion by Mentor against MDA, Lysonix and the Company for
    violation of Mentor's U.S. Patent No. 4886491. This patent covers Mentor's
    license for ultrasonic assisted liposuction. Damages were asserted in favor
    of Mentor for approximately $4,900,000 and $688,000 for interest. The court
    also granted a permanent injunction enjoining further sales of the Lysonix
    2000 in the United States for the use of liposuction. The Court affirmed
    that the lower court did not have the ability to increase damages or award
    attorneys' fees. Each defendant is jointly and severally liable as each
    defendant was deemed to infringe proportionally. Mentor requested further
    relief in the trial court for additional damages. The Company and its
    co-defendants are considering all alternatives including all legal measures
    that are available. Accordingly, the Company accrued an aggregate of
    $6,176,000 for damages, attorney's fees, interest and other costs during the
    third and fourth quarters of fiscal 2001. The Company paid approximately
    $100,000 of these accrued costs during the first fiscal quarter 2002.

5.   Income Taxes

     The Company recorded a deferred tax asset relating to the loss on
     impairment of equity investments for the notes and debentures to both
     Hearing Innovations, Inc. ("Hearing Innovations") and Focus Surgery, Inc.
     ("Focus Surgery") (note 6) during the first quarter of fiscal 2002 in the
     amount of $164,970. The Company recorded a full valuation allowance against
     the asset in accordance with the provisions of FASB Statement No. 109
     "Accounting for Income Taxes." The valuation allowance was determined by
     assessing the recoverability of the deferral tax asset. In assessing the
     recoverability of the deferral tax asset, management considered whether it
     is more likely than not whether some portion or all of the deferral tax
     asset would be realized. Based upon the nature of the deferral tax asset
     and the Company projections for future capital gains in which the deferral
     tax asset would be deductible, management did not deem the asset to be
     recoverable as of September 30, 2001. For the first quarter of fiscal 2001,
     the Company recorded a one-time tax benefit of $1,681,502 for the reduction
     of valuation allowance applied against a deferred tax asset recorded in
     fiscal year 1997 for below market stock option grants.

6.  Convertible Debentures and Loans

    During the first quarter of fiscal 2002, the Company entered into four loan
    agreements whereby Hearing Innovations was required to pay the Company

    May 30, 2002 and $32,700 due May 30, 2003. All notes bore interest at 8% per
    annum and contain warrants to acquire additional shares. The notes were
    secured by a lien on all of Hearing Innovations' right, title and interest
    in accounts receivable, inventory, property, plant and equipment, and
    processes of specified products whether now existing or hereafter arising
    after the date of these agreements. If the Company were to exercise and
    convert all warrants and options, the Company would hold an interest in

    approximately 35%. The Company recorded a loss for these loans since the
    Company does not anticipate that these loans will be paid in accordance with
    the contracted terms of the loan agreements.

    On August 3, 2001, the Company purchased a $300,000 6% Secured Cumulative
    Convertible Debenture from Focus Surgery, due December 22, 2002 (the "Focus
    Debenture"). The Focus Debenture is convertible into 250 shares of Focus
    Surgery preferred stock at the option of the Company at any time up until
    the due date at $1,200 per share. Interest accrues and is payable at
    maturity, or is convertible on the same terms as the Focus Debenture's
    principal amount. The Focus Debenture is secured by a lien on all of Focus
    Surgery's right, title, and interest in accounts receivable, inventory,
    property, plant and equipment and processes of specified products whether
    now existing or hereafter arising after the date of the Focus Debenture. The
    Company recorded a loss for the Focus Debenture since the Company does not
    anticipate such Debenture to be satisfied within the contractual terms of
    the loan agreement.

7.  Business Segments

    The Company operates in two business segments, which are organized by
    product types: industrial products and medical devices. Industrial products
    include the Sonicator ultrasonic liquid processor, Aura ductless fume
    enclosure, the Autoscope endoscope disinfectant system from Labcaire and the
    Mystaire scrubber. Medical devices include the Auto Sonix for ultrasonic
    cutting and coagulatory system and refurbishing revenues of high-performance
    ultrasound systems and replacement transducers for the medical diagnostic
    ultrasound industry. The Company evaluates the performance of the segments
    based upon income (loss) from operations less general and administrative
    expenses, bad debt expense and litigation settlement expenses. The
    accounting policies of the segments are the same as those described in the
    summary of significant accounting policies (Note 1) in the Company's Report
    on Form 10-K for the year ended June 30, 2001. Certain items are maintained
    at the corporate headquarters (corporate) and are not allocated to the
    segments. They primarily include general and administrative expenses, bad
    debt expense and litigation settlement expenses. The Company does not
    allocate assets by segment as they are not provided to the chief decision
    maker. Summarized financial information for each of the segments for the
    three months ended September 30, 2001 is as follows:

8.   Goodwill and Other Intangible Assets

     In July 2001, the Financial Accounting Standards Board issued Statement of
     Financial Accounting Standards Nos. 141 and 142 (SFAS 141 and SFAS 142),
     "Business Combinations" and "Goodwill and Other Intangible Assets,"
     respectively. SFAS 141 replaces APB 16 and requires the use of the
     purchase method for all business combinations initiated after June 30,
     2001. It also provides guidance on purchase accounting related to the
     recognition of intangible assets and the accounting for negative goodwill.
     SFAS 142 requires goodwill and intangible assets with indefinite useful
     lives to no longer be amortized, but instead be tested for impairment at
     least annually and whenever events or circumstances occur that indicate
     goodwill might be impaired.

     With the adoption of SFAS 142, the Company reassessed the useful lives and
     residual values of all acquired intangible assets to make any necessary
     amortization period adjustments. Based on that assessment, only goodwill
     was determined to have an indefinite useful life and no adjustments were
     made to the amortization period or residual values of other intangible
     assets. Amortization of goodwill for the comparable three month period
     ended September 30, 2000 was $130,382.

     SFAS 142 provides a six-month transitional period from the effective date
     of adoption for the Company to perform an assessment of whether there is an
     indication that goodwill is impaired. To the extent that an indication of
     impairment exists, the Company must perform a second test to measure the
     amount of impairment. The second test must be performed as soon as
     possible, but no later that the end of the fiscal year. Any impairment
     measured as of the date of adoption will be recognized as the cumulative
     effect of a change in accounting principle. Because of the extensive effort
     needed to complete this assessment, the Company has not determined whether
     there is any indication that goodwill is impaired or the estimated the
     amount of any potential impairment.

9.  Subsequent Events
    Labcaire Systems Ltd.

    In October 2001, under the terms of the revised purchase agreement (the
    "Labcaire Agreement") with Labcaire (as discussed in the Company's Report
    on Form 10-K for the year ended June 30, 2001), the Company paid
    approximately $97,000 for 9,286 shares (2.65%) of the outstanding common
    stock of Labcaire bring the acquired interest to 97.3 %. This represents
    the fiscal 2002 buy-back portion, as defined in the Labcaire Agreement. The
    Company is obligated to purchase 2.65% for the next year at which time the
    Company will own 100% of Labcaire.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
            =========================================================

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations.

NET SALES: Net sales of the Company's medical devices and industrial products
increased $31,203 from $6,791,318 for the three months ended September 30, 2000
to $6,822,521 for the three months ended September 30, 2001. This increase in
net sales is due to a $273,049 increase in medical devices partially offset by
$241,846 lower industrial product sales. The increase in medical devices is due
to the $205,084 increase in diagnostic medical devices and the increase of
$67,965 of Ultrasonic medical devices. The decrease in industrial sales is
predominantly due to the decrease of $479,594 in wet scrubber sales and $53,418
industrial ultrasonic products offset by an increase of $268,682 of Labcaire
sales and $22,484 of fume enclosure sales.

GROSS PROFIT: Gross profit decreased to 46.7% in the three months ended
September 30, 2001 from 52.7% in the three months ended September 30, 2000. The
decrease in gross profit is predominantly due to the unfavorable mix of high and
low margin product deliveries in medical devices.

SELLING EXPENSES: Selling expenses increased $208,483 from $821,462 for the
three months ended September 30, 2000 to $1,029,945 for the three months ended
September 30, 2001. Medical device selling expenses increased $77,886
predominantly due to additional sales and marketing efforts from diagnostic
medical devices. Industrial selling expenses increased $130,597 predominantly
due to increased market efforts and personnel additions.

GENERAL AND ADMINISTRATIVE EXPENSES: General and administrative expenses
decreased $52,293 from $1,539,825 in the three months ended September 30, 2000
to $1,487,532 in the three months ended September 30, 2001. The decrease is
predominantly due to the adoption with first quarter fiscal 2002 of FASB
Statement No. 142, "Goodwill and Other Intangible Assets" (SFAS 142). In
accordance with SFAS 142, the Company is no longer amortizing goodwill.
Amortization of goodwill for the comparable period in fiscal 2000 was $72,657.

RESEARCH AND DEVELOPMENT EXPENSES: Research and development expenses increased
$112,397 from $346,858 for the three months ended September 30, 2000 to $459,255
for the three months ended September 30, 2001. The increases are predominantly
due to the increased research and development on medical device products in the
amount of $114,399 offset by reduced efforts for industrial products in the
amount of $2,002.

OTHER INCOME (EXPENSES): Other expenses during the three months ended September
30, 2001 was $17,100. During the three months ended September 30, 2000 other
income was $260,334. The decrease of $277,434 was principally due to the
$422,183 recording of the loss for loans made to both Focus Surgery and Hearing
Innovations and lower interest income of $25,609 during the quarter ended
September 30, 2001, partially offset by increased royalties from medical devices
of $123,657. The Company is no longer amortizing goodwill for our interests in
Focus Surgery and Hearing Innovations for the first quarter ending September 30,
2001. Amortization of goodwill for the comparable period in fiscal 2000 was
$57,725.

            =========================================================

INCOME TAXES: The Company recorded a valuation allowance in the amount of
$164,970 for the first quarter of fiscal 2002 against the deferred tax asset
relating to the loss on the notes and debentures to both Hearing Innovations and
Focus Surgery. The valuation allowance was recorded in accordance with the
provisions of FASB Statement No. 109 "Accounting for Income Taxes." For the
first quarter of fiscal 2001, the Company recorded a one-time tax benefit of
$1,681,502 for the reduction of valuation allowance applied against a deferred
tax asset recorded in fiscal year 1997 for below market stock option grants.

            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)
            =========================================================

LIQUIDITY AND CAPITAL RESOURCES:

Working capital at September 30, 2001 and June 30, 2001 was $12,003,230 and
$12,002,501, respectively. Cash flow from operations was predominantly
negatively impacted by the increase in inventory from both industrial and
medical products, payment of litigation settlement liabilities, payment of
accounts payable and lower accrued expenses offset by increased accounts
receivable collections.

The Company is currently negotiating a $5,000,000 revolving credit facility with
a commercial bank to cover any potential shortfalls of the Company's cash
position as well as to support future working capital needs.

In October 2001, under the terms of the revised purchase agreement (the
"Labcaire Agreement") with Labcaire (as discussed in the Company's Report on
Form 10-K for the year ended June 30, 2001), the Company paid approximately
$97,000 for 9,286 shares (2.65%) of the outstanding common stock of Labcaire.
This represents the fiscal 2002 buy-back portion, as defined in the Labcaire
Agreement.

During the first quarter of fiscal 2002, the Company entered into four loan
agreements whereby Hearing Innovations was required to pay the Company amounts
of $13,000 due May 30, 2002, $22,800 due May 30, 2002, $27,200 due May 30, 2002
and $32,700 due May 30, 2003. All notes bore interest at 8% per annum and
certain warrants to acquire additional shares. The notes were secured by a lien
on all of Hearing Innovations' right, title and interest in accounts receivable,
inventory, property, plant and equipment, and processes of specified products
whether now existing or hereafter arising after the date of these agreements. If
the Company were to exercise and convert all warrants and options, the Company
would hold an interest in Hearing Innovations of approximately 35%. The Company
recorded the loss on such loans since the Company does not anticipate these
loans will be paid in accordance with the contracted terms of the loan
agreements.

On August 3, 2001, the Company purchased a $300,000 6% Secured Cumulative
Convertible Debenture from Focus Surgery, due December 22, 2002 (the "Focus
Debenture"). The Focus Debenture is convertible to 250 shares of Focus Surgery
preferred stock at the option of the Company at any time up until the due date
at $1,200 per share. Interest accrues and is payable at maturity, or is
convertible on the same terms as the Focus Debenture principal amount. The Focus
Debenture is secured by a lien on all Focus Surgery's rights, title, and
interest in accounts receivable, inventory, property, plant and equipment and
processes of specified products whether now existing or hereafter arising after
the date of the Focus Debenture. The Company recorded the loss on the Focus
Debenture since the Company does not anticipate such Debenture to be satisfied
within the contractual terms of the loan agreement.

The Company believes that its existing capital resources will enable it to
maintain its current and planned operations for at least 18 months from the date
hereof.

            =========================================================

Recent Accounting Pronouncements

In August 2001, the Financial Accounting Standards Board issued FASB Statement
No. 144, "Accounting for the Impairment of Disposal of Long-Lived Assets"
(Statement 144), which supersedes both FASB Statement No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
(Statement 121) and the accounting and reporting provisions of APB Opinion No.
30, "Reporting the Results of Operations-Reporting the Effects of Disposal of a
Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring
Events and Transactions" (Opinion 30), for the disposal of a segment of a
business (as previously defined in that Opinion). Statement 144 retains the
fundamental provisions in Statement 121 for recognizing and measuring impairment
losses on long-lived assets held for use and long-lived assets to be disposed of
by sale, while also resolving significant implementation issues associated with
Statement 121. For example, Statement 144 provides guidance on how a long-lived
asset that is used as part of a group should be evaluated for impairment,
establishes criteria for when a long-lived asset is held for sale, and
prescribes the accounting for a long-lived asset that will be disposed of other
than by sale. Statement 144 retains the basic provisions of Opinion 30 on how to
present discontinued operations in the income statement but broadens that
presentation to include a component of an entity (rather than a segment of a
business). Unlike Statement 121, an impairment assessment under Statement 144
will never result in a write-down of goodwill. Rather, goodwill is evaluated for
impairment under Statement No. 142, "Goodwill and Other Intangible Assets".

The Company is required to adopt Statement 144 no later than the year beginning
after December 15, 2001. Management does not expect the adoption of Statement
144 for long-lived assets held for use to have a material impact on the
Company's financial statements because the impairment assessment under Statement
144 is largely unchanged from Statement 121. The provisions of the Statement for
assets held for sale or other disposal generally are required to be applied
prospectively after the adoption date to newly initiated disposal activities.
Therefore, management cannot determine the potential effects that adoption of
Statement 144 will have on the Company's financial statements.

Forward Looking Statements: This report contains certain forward looking
statements within the meaning of Section 27A of the Securities Act and Section
21E of the Exchange Act, which are intended to be covered by the safe harbors
created thereby. Although the Company believes that the assumptions underlying
the forward looking statements contained herein are reasonable, any of the
assumptions could be inaccurate, and therefore, there can be no assurance that
the forward looking statements contained in this report will prove to be
accurate. Factors that could cause actual results to differ from the results
specifically discussed in the forward looking statements include, but are not
limited to, the absence of anticipated contracts, higher than historical costs
incurred in performance of contracts or in conducting other activities, product
mix in sales, results of joint venture and investment in related entities,
future economic, competitive and market conditions, the outcome of legal
proceedings, particularly those including patent litigation with Mentor
Corporation as well as management business decisions.

                          QUANTITATIVE AND QUALITATIVE
                          DISCLOSURES ABOUT MARKET RISK
            =========================================================

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Currency Risk:

                    Approximately 26% of the Company's revenues in fiscal 2001
were received in English Pounds Sterling currency. To the extent that the
Company's revenues are generated in English Pounds, its operating results are
converted into U.S. Dollars using rates of 1.46 and 1.48 for the three months
ended September 30, 2001 and 2000, respectively. A strengthening of the English
Pound, in relation to the U.S. Dollar, will have the effect of increasing its
reported revenues and profits, while a weakening of the English Pound will have
the opposite effect. Since the Company's operations in England generally sets
prices and bids for contracts in English Pounds, a strengthening of the English
Pound, while increasing the value of its UK assets, might place the Company at a
pricing disadvantage in bidding for work from manufacturers based overseas.

                    Euro Conversion: The January 1, 1999 adoption of the Euro
created a single-currency market in much of Europe. For a transition period from
January 1, 1999 through January 1, 2002, the existing local currencies are
anticipated to remain legal tender as denominations of the Euro. The Company
does not anticipate that its operations will be materially adversely effected by
the conversion to the Euro. The Company has analyzed the impact of conversion to
the Euro on its existing systems and operations and implemented modifications to
its systems to enable the Company to handle Euro invoicing for the transactions
which commenced in 1999. The Company anticipates that the cost of such
modifications should not have a material effect on its consolidated results of
operations or liquidity.

PART II -    OTHER INFORMATION

    Item 1.   Legal Proceedings.
    The Company, Medical Device Alliance, Inc. ("MDA") and MDA's wholly-owned
    subsidiary, Lysonix, Inc. ("Lysonix"), were defendants in an action alleging
    patent infringement filed by Mentor Corporation ("Mentor"). On June 10,
    1999, the United States District Court, central District of California,
    found for the defendants that there was no infringement upon Mentor's
    patent. Mentor subsequently filed an appeal. The issue concerned whether
    Mentor's patent is enforceable against the Company and does not govern
    whether the Company's patent in reference is invalid. On April 11, 2001, the
    United States Court of Appeals for the Federal Circuit Court issued a
    decision reversing in large part the decision of the trial court and
    granting the motion by Mentor against MDA, Lysonix and the Company for
    violation of Mentor's U.S. Patent No. 4,886,491. This patent covers Mentor's
    license for ultrasonic assisted liposuction. Damages were asserted in favor
    of Mentor for approximately $4,900,000 and $688,000 for interest. The court
    also granted a permanent injunction enjoining further sales of the Lysonix
    2000 in the United States for the use of liposuction. The Court affirmed
    that the lower court did not have the ability to increase damages or award
    attorneys' fees. Each defendant is jointly and severally liable as each
    defendant was deemed to infringe proportionally. Mentor requested further
    relief in the trial court for additional damages. The Company and its
    co-defendants are considering all alternatives including all legal measures
    that are available. Accordingly, the Company accrued an aggregate of
    $6,176,000 for damages, attorney's fees, interest and other costs during the
    third and fourth quarters of fiscal 2001. The Company paid approximately
    $100,000 of these accrued costs during the first fiscal quarter of 2002.

Employee stock options totaling 280,813 for the three months ended September 30,
2001 were not included in the dilutive net loss per share calculation because
the effect would have been anti-dilutive. There were no anti-dilutive stock
options for the three months ended September 30, 2000.

(b) There were no reports on Form 8-K filed during the quarter ended September
30, 2001.
