5. BAD DEBT EXPENSE

On October 22, 1998, the Company announced that it had reserved for possible bad
debts of $1,700,000 against accounts receivable due and owing by Medical Device
Alliance, Inc. ("MDA") and its wholly-owned subsidiary, LySonix, Inc.,
("Lysonix") as Licensees for the Misonix ultrasonic soft tissue aspirator. In
December of 1998, an additional reserve was taken against all remaining
receivables from MDA and Lysonix totaling $369,903. The allowance for doubtful
accounts of $1,592,235 and $477,668 relates to product shipments and royalties,
respectively. A notice of default on the license agreement with these parties
has been transmitted by the Company pursuant to which the license agreement was
terminated on January 11, 1999. (See Note 9)


6. STOCK BASED COMPENSATION

On October 7, 1998, the Board of Directors adopted, and on January 13, 1999, the
shareholders approved the 1998 Employee Stock Option Plan covering an aggregate
of 500,000 common shares of the Company.


7.  DEBT

On January 22, 1999, Labcaire purchased a manufacturing facility in North
Somerset, England to house their operations. The transaction totaled or
approximately $2,000,000 and was financed with a mortgage loan from Midland Bank
plc. which as of March 31, 1999, had an outstanding balance of $1,258,593.
Midland Bank plc also reduced their line of credit with Labcaire. The revised
agreement, dated December 4, 1998, reduces the available credit from $871,500 to
$581,000 and requires that Labcaire pay the existing loan balance down to
$581,000 by January 31, 1999. On December 11, 1998, the Company transferred
$335,900 to Labcaire to satisfy this requirement. During the third quarter of
fiscal 1999, the line of credit was temporarily increased to pay refundable
sales tax on their new facility $290,500. The new terms also stipulate that
Labcaire's accounts receivable must be at least 175% of the outstanding balance
on the line of credit at all times, and that Labcaire must show an after tax
profit of at least $166,000 for the prior four quarters. As of March 31, 1999
$735,708 was outstanding under this line of credit.


8.  ACQUISITION

In October 1998, under the terms of the revised purchase agreement (the
"Agreement") with Labcaire (as discussed in the Form 10-KSB at June 30, 1998,
the Company paid $129,172 for 9,286 shares (2.65%) of Labcaire's common stock.
This represents the fiscal 1998 buy- back portion, as defined in the Agreement.

9. COMMITMENTS AND CONTINGENCIES

EMPLOYEE AGREEMENTS

The Company has entered into an employee agreement with its chief executive
officer which expires on October 31, 2000. This agreement provides for an annual
base compensation of $250,000 with an annual bonus at the discretion of the
Board of Directors. The agreement also provides for a guaranteed initial bonus
of $225,000 to be paid in January 2000.

LEGAL PROCEEDINGS

The Company, MDA and MDA's wholly-owned subsidiary, Lysonix, were sued for
alleged patent infringement by Mentor Corporation. The case was heard in U.S.
District Court in January 1999. On February 5, 1999, the jury found for the
plaintiff. As a result of this outcome, the Company and its licensee are
precluded from selling the ultrasonic soft tissue aspirator. The amount of
damages are approximately $4,904,000 against the Company and the licensees of
its device. (See Note 10 for further discussion.)

10.  SUBSEQUENT EVENTS

On April 30, 1999, the Company and Focus Surgery, Inc. ["Focus"] a
privately-held Indianapolis firm, jointly announced an agreement in principle
whereby Misonix will invest $3 million to obtain an approximately 20% equity
position in Focus. The agreement further provides for a series of development
and manufacturing agreements whereby Misonix would upgrade existing Focus
products and create new products based on high intensity focused ultrasound
(HIFU) technology for the non-invasive treatment of tissue for certain medical
applications. The agreement in principal contemplates and is subject to the
finalization and execution of formal, legally binding agreements between the two
companies. This agreement with Focus was consummated on May 7, 1999.

On May 3, 1999, the Company entered into an agreement for the settlement of the
patent litigation instituted by Mentor against Misonix. The terms of the
settlement being presented to the District Court in Los Angeles hearing the
matter are comprised of (a) a settlement and release by Mentor of Misonix in the
patent litigation, (b) a cross licensing agreement whereby each would license
the other to use each other's patent and technology, (c) a manufacturing and
supply agreement whereby Misonix would ultimately become the sole source of
ultrasonic liposuction equipment sold by Mentor, whether under the Mentor or the
Misonix patent and technology, (d) Misonix would make a prepayment of $1,500,000
as an advance royalty to Mentor under the cross licensing agreement, (e) Misonix
would be selected to develop and manufacture the next generation of liposuction
equipment, and (f) Mentor would have sole worldwide sales and marketing rights
to the products.  The settlement is subject to court

approval and the execution and delivery of formal documents implementing the
cross licensing, supply and development agreements, which is anticipated to
occur within thirty days. The settlement agreement does not affect Mentor's
claims against the Misonix licensees, Medical Device Alliance, Inc. and Lysonix,
Inc., whose rights under the license agreement have previously been terminated
by Misonix. On May 10, 1999 the Company brought an action against these former
licensees seeking collection of indebtedness and enforcement of its security
interest against remaining portion of inventory and for other relief.

On May 11, 1999, Misonix and Hearing Innovations Incorporated (Hearing
Innovations) jointly announced an agreement in principal whereby Misonix will
invest $750,000 to obtain an approximately 7% equity position in Hearing
Innovations. The $750,000 interest will be provided from a $500,000 additional
capital contribution and the conversion of the $250,000 note receivables into
equity. The agreements also state that upon the exercise of the first warrant,
Misonix has the right to manufacture Hearing Innovations ultrasonic products and
also has the right to create a joint venture for the marketing and sale of
Hearing Innovations' ultrasonic tinnitus masker device.

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


Results of Operations

Nine and three months Ended March 31, 1999 and 1998

Net Sales: Net sales of the Company's medical, scientific and industrial
products for the nine months ended March 31, 1999, decreased $109,910 or 1% to
$17,244,068 from $17,353,978 for the nine months ended March 31, 1998. Net sales
for the Company's medical, scientific and industrial products for the three
months ended March 31, 1999 decreased $696,182 or 11% to $5,820,288 from
$6,516,470 for the three months ended March 31, 1998. The decrease in sales is
due to a decrease in medical shipments due to a delay in orders received for our
licensee, US Surgical, as well as a reduction in shipments of Mystaire Division
products due to concentrated efforts on shipments for the fourth quarter for two
major orders. The backlog for unfilled orders as of March 31, 1999 was
$10,033,145.

Gross Profit: Gross Profit decreased from 53.3% of sales for the nine months
ended March 31, 1998 to 49.9% sales for the nine months ended March 31, 1999 due
to an unfavorable mix of high and low margin product deliveries and disposal of
obsolete inventory. Gross Profit increased from 50.7% of sales for the three
months ended March 31, 1998 to 51.2% of sales for the three months ended March
31, 1999. The increase is due to a favorable mix of high and low margin product
deliveries.

Selling, General and Administrative Expenses: Selling, general and
administrative expenses increased from $5,245,296 (30.2% of sales) for the nine
months ended March 31, 1998 to $5,599,413 (32% of sales) for the nine months
ended March 31, 1999 due to higher selling expenses in addition to legal fees
associated with the Mentor Patent Litigation.. (See Note 9) Selling, general and
administrative expenses increased from $1,862,492 (28.5% for sales) for the
three months ended March 31, 1998 to $2,050,907 (35.2% of sales) for the three
months ended March 31, 1999. This increase relates to an increase in consulting
and accounting expenses related to the change in the financial management of the
Company. 

Bad Debt Expense: Bad debt expense increased from $36,000, for the nine
months ended March 31, 1998 to $2,115,300 for the nine months ended March 31,
1999. On October 22, 1998 the Company announced that it had reserved for
possible bad debts of $1,700,000 against accounts receivable due and owing by
MDA and its wholly-owned subsidiary, Lysonix, Inc., as Licensees for the Misonix
Ultrasonic soft tissue aspirator. In December 1998, an additional reserve of
$369,903 was provided for all remaining receivables from MDA and Lysonix, Inc.,
to bring the reserve to $2,069,903 for MDA. A notice of default on the license
agreement with these parties has been transmitted by the Company which declared
the license agreement was terminated on January 11, 1999. On May , 1999 the
Company brought an action against licensee seeking collection of indebtedness
and enforcement of security interest against remaining portion of inventory.
Without the effects of this charge, the Company would have reported net income
of $2,116,783 or $.32 diluted earnings per share for the nine months ended March
31, 1999 as compared to net income of $2,886,620 or $.43 diluted earnings per
share for the nine months ended March 31, 1998. Due to this charge, the Company
reported a net profit of $750,647 or $.11 diluted earnings per share for the
nine months ended March 31, 1999.

Research and Development Expenses: Research and development expenses were
$704,581 for the nine months ended March 31, 1998 and $827,060 for the nine
months ended March 31, 1999. Research and

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


development expenses were $256,878 for the three months ended March 31, 1998 and
$384,551 for the three months ended March 31, 1999. The increase in this area is
predominately due to development costs associated with the Company's medical
devices and ultrasonic products.

Other Income (Expense): Other income during the nine months ended March 31, 1999
was $1,012,727 compared to $746,123 for the nine months ended March 31, 1998.
Other income for the three months ended March 31, 1999 was $272,644 as compared
to $259,986 for the three months ended March 31, 1998. This increase was
principally due to increased royalty income received from the Company's licensee
on sales of medical devices and interest income on investments.

Income Taxes: The Company is currently providing for income taxes at a rate of
34%. The estimated payments made to date exceed the income tax provision and
result in prepaid income taxes rather than income taxes payable which is
classified in the balance sheet as prepaid expenses and other current assets.

Liquidity and Capital Resources: Working capital at March 31, 1999 and June 30,
1998 was $18.4 and $18.0 million, respectively. Cash and investments increased
by approximately $2.83 million from June 30, 1998. The increase is due to
increased cash flow from operations, royalties received from the Company's
licensees on sale of medical devices and interest income. This increase was
partially offset by entering into an agreement with Hearing Innovations, the
purchase of a manufacturing facility in North Somerset, England, and the
additional investment in the Labcaire subsidiary.

The Company has a revolving credit facility, which expires on June 30, 1999, in
the amount of $500,000 available to the Company for short term borrowings and
letters of credit. Borrowings under the facility bear interest at prime plus 2%
and are collateralized by a security interest in all assets of the Company.
There are no outstanding borrowings under this facility.

On January 22, 1999, Labcaire, the Company's 89.34% owned subsidiary, purchased
a manufacturing facility in North Somerset, England to house their operations.
The transaction, totaling $2.1 million, consisted of a purchase price of
$1,660,000, closing costs of $117,860 and refundable VAT of $290,500. The
purchase was financed in part by an intercompany loan of $335,900 and by a
$1,294,800 mortgage loan from Midland Bank plc in North Somerset. Borrowings
under the facility bear interest at prime plus 2% and are collateralized by a
security interest in all assets of Labcaire. The loan is payable in monthly
installments of $ 12,876 per month, including interest, over a term of fifteen
years starting in February of 1999. There is also a 1% prepayment penalty for
early retirement of the loan. As of March 31, 1999, $1,258,593 was the
outstanding balance of the loan.

As a result of the mortgage loan described above, Midland Bank plc revised their
line of credit with Labcaire. The revised agreement, dated December 4, 1998,
reduces the available credit from $871,500 to $581,000 and requires Labcaire to
pay the existing loan balance down to $581,000 by January 31, 1999. On December
11, 1998 the Company transferred $335,900 to Labcaire to satisfy this
requirement. During the third quarter of fiscal 1999, the line of credit was
temporarily increased by $290,500 to pay refundable sales taxes on their new
facility. As of March 31, 1999, $735,708 was outstanding under this facility.

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


On March 10, 1999, the Company entered into an agreement with Hearing
Innovations, whereby Hearing Innovations promises to pay to the Company, on or
before the first anniversary date of the agreement, the principal amount of
$250,000. This amount bears no interest. The note is secured by a lien on all
Hearing Innovation's right, title and interest in accounts receivable,
inventory, property plant and equipment and proceeds of specified products
whether now existing or hereafter arising or acquired. On May 11, 1999 Misonix
and Hearing Innovations jointly announced an agreement in principle whereby
Misonix will invest $750,000 to obtain an approximately 7% equity position in
Hearing Innovations. The $750,000 interest will be provided from $500,000
additional paid in capital and the conversion of the $250,000 note receivable
into equity. This agreement further provides for the issuance of warrants that
if exercised gives Misonix the right to invest in Hearing Innovations. If both
warrants are exercised, it would bring Misonix's equity position to
approximately 15% in Hearing Innovations.

The Company believes that its existing capital resources will enable it to
maintain its current and planned operations for a least 12 months from the date
hereof.

Year 2000 Compliance: During the first quarter of Fiscal 1998, the Company
commenced a Year 2000 date conversion project to address necessary changes,
testing and implementation in respect to its internal computer systems. Project
completion is scheduled for June 1, 1999. To date, the cost of this project has
not been material to the Company's results of operations and liquidity and the
Company does not anticipate that the cost of completing the project will be
material to its results of operations or liquidity in fiscal 1999. Management
anticipates that the Company's Year 2000 date conversion project as it relates
to the Company's internal systems will be completed on a timely basis.

The Company's applicable products are Year 2000 compliant.

The Company is currently seeking information regarding Year 2000 compliance from
its vendors, customers and manufacturers. Project completion for this phase is
planned for the middle of 1999. However, given the reliance on third-party
information as it relates to their compliance programs and the difficulty of
determining potential errors on the part of the external service suppliers, no
assurance can be given that the Company's information systems or operations will
not be affected by mistakes, if any, of third parties or third-party failures to
complete the Year 2000 project on a timely basis. There can be no assurance that
the systems of other companies on which the Company's systems rely will be
timely converted or that any such failures to convert by another company would
not have an adverse effect on the Company's systems.

The cost of the Company's Year 2000 project and the date on which the Company
believes it will complete the necessary modifications are based on the Company's
estimates, which were derived utilizing numerous assumptions of future events,
including the continued availability of resources, third party modification
plans and other factors. The Company presently believes that the Year 2000 issue
will not pose significant operational problems for its internal information
systems and products. However, if the

            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)



anticipated modifications and conversions are not completed on a timely basis,
or if the systems of other companies on which the Company's systems and
operations rely are not converted on a timely basis, the Year 2000 issue could
have an adverse effect on the Company's operations.

The Company does not currently have any contingency plans in place to address
the failure of timely conversion of its and/or third-party systems in respect of
the Year 2000 issue.

Euro Conversion: The January 1, 1999 scheduled 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 system and operations and implemented modifications to its
systems to enable the Company to handle Euro invoicing for the transaction which
commenced in 1999. The Company anticipates that the cost of such modifications
should not have a material adverse effect on its results of operations or
liquidity.

In the opinion of management, inflation has not had a material effect on the
operations of the Company. 

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, future 
economic, competitive and market conditions, the outcome of legal proceedings, 
as well as management business decisions.
