                                     PART I

Item 1.   Description of Business.

     Misonix, Inc. (the "Company") is a New York Corporation which, through its
predecessors, was first organized in 1959. The Company designs, develops,
manufactures and markets ultrasonic equipment for scientific and industrial
applications, ductless fume enclosures for filtration of gaseous contaminates,
and environmental control products for the abatement of air pollution, as well
as medical devices. Other products manufactured or distributed by the Company
include ultrasonic cleaners and spray nozzles. In December 1995, the Company
entered into a license agreement with Medical Device Alliance, Inc.("MDA"),
giving MDA exclusive world-wide marketing and sales rights for the Company's
ultrasonic soft tissue aspiration medical device. In September 1996, the Company
began manufacturing this device for MDA and recognized its first revenues for
this product(see "Medical Products").

Medical Products

     In December 1995, the Company entered into a license agreement with Medical
Device Alliance, Inc.("MDA"), giving MDA exclusive world-wide marketing and
sales rights for the Company's ultrasonic soft tissue aspiration medical device.
Pursuant to the License Agreement, the Company has received aggregate licensing
fees of $500,000 plus royalties based upon net sales of such products. Also as
part of the agreement, the Company was reimbursed a maximum of $30,000 per month
(commencing September 1995) for product development expenditures (as defined in
the agreement). The amount of reimbursements for the years ended June 30, 1997
and 1996 were $127,487 and $320,363, respectively. This license deals with,
among other matters, the Company's patent for a liposuction apparatus granted in
May, 1995 and its 510(K) approval from the United States Food and Drug
Administration to market and sell a device for ultrasonic tissue aspiration. In
September 1996, the Company began manufacturing this device for MDA and
recognized its first revenues for this product. Total sales of this product were
approximately $5,200,000 during the fiscal year ended June 30, 1997.

     The Company has settled the dispute (as discussed in prior filings) with
the two individuals who are joint inventors, with the Company's founder, of the
Patent for a Liposuction Method and Apparatus. As a result, they have
reconfirmed their assignment, and in return, the Company has reestablished the
original payment agreement which gives the two inventors a 5% royalty on
revenues covered, including those received from the MDA License.

     A competitor, Mentor Corporation, has brought an action against the
Company, MDA, and a subsidiary of MDA alleging patent

                                        2


<PAGE>




infringement. The Company and its licensee are vigorously contesting and
defending against this claim (see "Item 3 Legal Proceedings")

     In October 1996, the Company entered into a license agreement, with United
States Surgical Corporation ("USS"), covering the further development and
commercial exploitation of the Company's medical technology relating to
ultrasonic cutting, which uses high frequency sound waves to coagulate and
divide tissue for both open and laparoscopic surgery. The license agreement
gives USS exclusive world-wide marketing and sales rights for this technology.
The Company received $100,000 under the option agreement preceding the license
agreement. Under the license agreement, the Company is entitled to receive
aggregate fees of approximately $500,000, subject to attaining certain
milestones over the term of the agreement, plus royalties based upon net sales
of such products. As of June 30, 1997, the Company has received $275,000 under
the license agreement.

     Revenue from both the MDA and the USS License Agreements is recognized
ratably over the respective terms of the Agreement.


Scientific and Industrial Products

     The Company's other revenue-producing activities consist of the manufacture
and sale of the Sonicator(R) ultrasonic liquid processor and cell disruptor, the
distribution of other ultrasonic equipment for scientific and industrial
purposes, the manufacture and sale of Mystaire(R) ductless fume enclosures for
filtration of gaseous contaminants and the manufacture and sale of Mystaire
scrubbers for the abatement of air pollution.

     The Sonicator is used in laboratories as a biological cell and tissue
disruptor and for the preparation of substances used to target drug delivery in
the body and certain agents used to visualize the circulatory system
non-invasively. In analytical chemistry, ultrasonic processors such as the
Sonicator remove gases from solvents and prepare samples for chemical analysis.
Similar procedures are used in biotechnology in the production of medications
and chemicals. The Sonicator is also used in the acceleration of chemical
reactions and the extraction of proteins from cells such as E.coli and yeast.
Sonication can strip away the outer coating of a virus and fragment DNA for
immunological studies. It is also widely applied in manufacturing
pharmaceuticals, fuel/oil emulsions, homogenizing pigments and dyes and
improving the quality and consistency of these products. Additional uses of the
Sonicator are, among others, quality control, including the dispersion of black
carbon in the ink industry, improving polymer films, degassing carbonated
beverages, beer, wines and spirits, and solvents.


                                        3


<PAGE>




     In addition to the Sonicator, the Company also manufactures and sells an
ultrasonic spray nozzle, marketed under the name Sonimist(R), and distributes
ultrasonic cleaners, marketed under the names Astrason(R) bench-top cleaner and
Astramax(R) industrial ultrasonic cleaner. The Sonimist ultrasonic spray nozzles
are used for, among other things, coating, cleaning, cooling and disinfecting
products in the food, pharmaceutical, paint, chemical, electronic, environmental
and printing industries. Ultrasonic cleaners are marketed to research and
industrial laboratories to remove various contaminants, such as radioactive
particles, proteins, rust, blood and oil, from laboratory equipment.

     The Mystaire fume enclosure is a ductless filtration and containment hood
which is portable and easy to install. It eliminates the duct work that is
otherwise necessary for exhausting to the outside air. The enclosure is sold to
clinical, research, and industrial laboratories for various industrial purposes.
Laboratory applications include working with organic solvents and radioisotopes,
chemical storage, chemical dispensing, pathology and histology. Industrial
markets for the product line include the pharmaceutical, semiconductor
manufacturing, and asbestos containment industries. The Mystaire air purifier is
a general purpose recirculating system with activated carbon filters that purify
air and remove airborne fumes, odors, and particulates. A new product which
utilizes the same technology as the Mystaire fume enclosure, the Forensic
Evidence Cabinet, is being marketed to crime labs, medical examiners, and police
stations. Its primary use is to insure proper storage and minimize cross
contamination as well as protect staff from exposure to airborne pathogens
during storage of evidence.

     The Mystaire scrubber is an air pollution abatement system which removes
difficult airborne contaminants emitted from laboratory, industrial and sewage
treatment processes. The scrubber operates on broad range of contaminants and is
particularly effective on gaseous contaminants such as sulfur oxides. The
Company also manufactures a range of "point of use" scrubbers for the
microelectronics industry. This equipment eliminates low levels of toxic and
noxious contaminants arising from silicon wafer production.

     The Company owns an 84.05% interest in Labcaire Systems Ltd. ("Labcaire"),
a United Kingdom company formed in February 1992 with its principal place of
business in Clevedon, England. The balance of the capital stock of Labcaire is
owned by four executives who have, under a purchase Agreement ("Agreement"),
agreed to sell one-seventh of their total holding of Labcaire shares to the
Company in each of seven consecutive years, commencing with the fiscal year
ended 1996. Under the Agreement, the Company is required to repurchase such
shares at a price equal to one-seventh of each executive's prorata share of 8.5
times Labcaire's earnings before interest, taxes, and management charges

                                        4


<PAGE>



for the preceding fiscal year. Pursuant to the Agreement, 9,284 shares (2.65%)
of Labcaire common stock was purchased by the Company for (pound)62,388

(approximately $102,100), in October 1996, for the year ended June 30, 1996 and
9,286 shares (2.65%) will be purchased by the Company for (pound)70,666
(approximately $114,500)for the year ended June 30, 1997. The effective date of
this transaction is expected to be October 1997. Labcaire's business consists of
designing, manufacturing, and marketing air handling systems for the protection
of personnel, products and the environment from airborne hazards. Labcaire is
the European distributor of the Company's ultrasonic scientific and industrial
products. The present management of Labcaire consists of four
executives/minority interest shareholders with experience in chemical
containment and air handling technologies. Labcaire manufactures class 100
biosafety hazard enclosures, used in laboratories to provide sterile
environments and protect lab technicians from airborne contaminants, and class
100 laminar flow enclosures. Labcaire also manufactures the Company's ductless
fume enclosures for the European market and sells the enclosures under its
tradename. Labcaire has developed and now manufactures and sells an automatic
endoscope disinfection system ("Autoscope"). The Autoscope disinfects and rinses
several endoscopes while abating the noxious disinfectant fumes.

Market and Customers

     The Company relies on its joint venture partner, MDA, for marketing its
ultrasonic soft tissue aspiration medical device and, with respect to any other
potential ultrasonic medical devices, will likely seek and rely upon other joint
venture partners.

     The largest market for the Company's Sonicator includes research and
clinical laboratories worldwide. In addition, the Company has expanded its sales
of the ultrasonic processor into industrial markets such as paint, pigment,
ceramic and pharmaceutical manufacturers.

     The Company views a wide range of industries as prospective customers for
its pollution abatement scrubbers. Scrubbers are usable in any industry or
environment in which airborne contaminants are created.

     The market for the Company's ductless fume enclosures includes laboratory
or industrial environments in which workers may be exposed to noxious fumes or
vapors. The products are suited to laboratories in which personnel perform
functions which release noxious fumes or vapors (including hospital and medical
laboratories), industrial processing (particularly involving the use of
solvents) and soldering and other general chemical processes. The products are
particularly suited to users in the pharmaceutical, semiconductor,
biotechnology, and forensic industries.

                                        5


<PAGE>



     The Company relies on manufacturing representatives, distributors, direct
salespersons and catalogue listings for the marketing of its scientific and
industrial products. The Company currently sells through more than ten
manufacturing representatives and distributors in the United States. The Company

currently employs two direct sales persons who operate outside the Company's
offices and conduct direct marketing on a regional basis, two sales specialists,
one marketing manager, and a vice-president of sales and marketing who work in
the Company's offices. Approximately 9% of its sales are through catalogue
distributors. The Company's sales efforts include advertising and participating
in trade shows.

     In fiscal 1997, approximately 36.8% of the Company's net sales were to
foreign markets. Labcaire, a subsidiary of the Company, acts as the European
distributor of the Company's scientific and industrial products and manufactures
and sells the Company's fume enclosure line as well as its own range of
laboratory environmental control products. Sales by the Company in other major
industrial countries are made through distributors.

Manufacturing and Supply

     The Company manufactures and assembles the majority of its scientific and
industrial products and its medical devices at its production facility located
in Farmingdale, New York. The Company's products include components manufactured
by other companies in the United States. The Company believes that it will not
encounter difficulty in obtaining materials, supplies and components adequate
for its anticipated short-term needs. The Company is not dependent upon any
single source of supply and has no long-term supply agreements.

     Labcaire manufactures and assembles its products at its facility located in
Clevedon, England. It is not dependent upon any single source of supply and has
no long-term supply agreements.

Competition

     Competition in the medical and medical device industry is rigorous with
many companies having significant capital resources, large research laboratories
and extensive distribution systems in excess of the Company's. Accordingly, the
Company believes participation in this field is only feasible if it enters into
strategic alliances and/or joint ventures with other entities having greater
experience and resources for use in this field.

     Competitors in the ultrasonic industry for industrial products range from
large corporations with greater production and marketing capabilities to smaller
firms specializing in single products. The Company believes that its significant
competitors in the manufacture and distribution of industrial ultrasonic devices

                                        6


<PAGE>



are Branson Sonic Power, a division of Emerson Electric Co., and Sonics &
Materials, Inc. In addition, the Company is aware of at least four other
manufacturers of ultrasonic liquid processors. It is possible that other
companies in the industry are currently developing products with the same
capabilities as those of the Company. The Company believes that the features of

its Sonicator and the Company's customer assistance in connection with
particular applications give the Sonicator a competitive advantage over
comparable products.

     Competitors in the air pollution abatement industry range from large,
multi-national corporations with greater production and marketing capabilities
to small firms specializing in single products. The Company competes with other
entities whose financial resources are substantially greater and, in many cases,
whose share of the air pollution abatement market is significant. The Company
believes that its principal competitors in the manufacture and distribution of
scrubbers are The Ceilcote Company, Inc., Duall Division, a division of Met-Pro
Corporation, and Croll-Reynolds Company, Inc. The principal competitor for the
ductless fume enclosure is Captair, Inc. The Company believes that specific
advantages of its scrubbers include efficiency, price and customer assistance
and that specific advantages of its fume enclosures include efficiency and other
product features, such as durability and ease of operation.

Patents, Trademarks, Trade Secrets and Licenses

     The Company owns United States trademark registrations for the following
marks: Mystaire, Waterweb, Sonimist, Astrason and Astramax. Pursuant to a
royalty free license agreement with an unaffiliated third party, the Company has

Fiscal years ended June 30, 1996 and 1997

     Net Sales. Net sales increased by 77.2% between the fiscal year ended June
30, 1996 and the fiscal year ended June 30, 1997 from $9,913,136 to $17,560,041.
Approximately two-thirds of this increase was due to the Company's first medical
device sales which were approximately $5,200,000 during the fiscal year ended
June 30, 1997.


     Fume enclosures increased by $1,101,000 or 17.9% in the fiscal year ended
1997 due to increased marketing efforts for its domestic products and the
continued success of Misonix's forensic cabinet and Labcaire's Autoscope.

     Ultrasonic products include the Sonicator liquid processor and cell
disrupter systems, ultrasonic cleaners, related accessories, and repair and
service. The increase of $542,000 or 20.6% in sales of ultrasonic products in
fiscal 1997 is the result of new marketing strategies which increased catalog
sales and allowed the Company to increase its market share.

                                       12


<PAGE>



     The increase of $787,000 or 68.1% in scrubber sales between fiscal 1996 and
fiscal 1997 was due to increased marketing efforts to the microelectronics
industry.

     The medical device product category had its first revenues in the fiscal
year ended June 30, 1997. Its revenues of $5,217,000 is the result of the
Company's strategic alliance with MDA.

     During fiscal 1996 and fiscal 1997 the Company had foreign net sales of
$5,643,101 and $6,465,673, respectively, representing 56.9% and 36.8% of net
sales for such years, respectively. This increase in sales is principally due to
Labcaire's increased sales volume in fiscal 1997 over fiscal 1996, increasing to
$5,469,992 from $4,711,667. The decrease in foreign sales as a percent of total
sales is a result of the Company selling approximately $5,200,000 of medical
devices domestically during fiscal 1997. There were no such sales during fiscal
1996.

     Gross profit. There was an increase in overall gross profit margin to 56.8%
in fiscal 1997 from 47.7% in fiscal 1996 because of economies of scale resulting
from increased sales volume, sales of higher gross profit products(i.e., the
newly introduced medical device),and various product price increases.

     Selling, general and administrative expenses. There was a 32.7% increase,
from $4,139,183 to $5,492,087 in SG&A expenses from fiscal 1996 to fiscal 1997
owing in part to higher commissions on increased sales volume and the hiring of
additional employees. However, this increased sales volume resulted in a
decrease of these expenses to 31.3% of net sales in fiscal 1997 compared to
41.8% in fiscal 1996.

     Research and development expenses. Medical product research and development
expenses were $42,933 in fiscal 1996 and $105,120 in fiscal 1997. The increase
in medical product R&D expenses is due to non-funded development costs,
associated with the Company's medical devices, under its agreements with Medical
Device Alliance Inc. and U.S. Surgical Corporation. Industrial product R&D
expenses were $161,253 in fiscal 1996 and $245,668 in fiscal 1997.

     Interest expense. Interest expense was $41,529 in fiscal 1996 and $40,953

in fiscal 1997. This decrease was due to a slightly lower level of borrowing by
Labcaire during the fiscal year.

     Option/license Fees. In December 1995, the Company entered into a licensing
agreement with Medical Device Alliance, Inc. ("MDA"). As part of this agreement,
the Company has received $500,000 in licensing fees, of which $45,000 and
$19,167 has been recorded as income during fiscal 1997 and fiscal 1996,

                                       13


<PAGE>



respectively. In October 1996, the Company entered a licensing agreement with
United States Surgical Corporation ("USS"). The Company received $100,000 under
the option agreement preceding the license agreement and has received $275,000
under the license agreement. The Company has recorded $100,000 of the option
fees and $10,312 of the licensing fees as income during fiscal 1997.

     Net operating losses. The Company has accumulated approximately $2,000,000
of net operating losses as of June 30, 1997, which may be used to reduce taxable
income and income taxes in future years. The utilization of these losses to
reduce future income taxes will depend on the generation of sufficient taxable
income prior to the expiration of the net operating loss carryforwards. The
carryforwards begin to expire in fiscal year 2002 and will continue to expire
through fiscal year 2011.

Liquidity and Capital Resources:

     On February 3, 1997, 1,093,692 publicly issued Redeemable Warrants were
exercised and a like number of common shares were issued. The balance of these
options, which were originally issued at the time of the Company's initial
public offering in January 1992, expired. As a result of the exercise, the
Company received proceeds of $5,655,924, net of expenses of approximately
$31,000.

     At June 30, 1997, the Company had a cash and cash equivalent balance of
$5,409,830 and investments held to maturity of $6,367,595.

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

Currency Risk:

     Approximately 31% of the Company's revenues in fiscal 1997 were received in
English Pounds Sterling currency. To the extent that the Company's revenues are
generated in English Pounds and, for purposes of the Company reporting its
financial position, its operating results are converted into US Dollars using
rates of 1.62 and 1.55 in the years ended June 30, 1997 and 1996, respectively.
A strengthening of the English Pound, in relation to the US 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 set 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.

Other:

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

     Automated Quotation System) at June 30, 1997 minus the exercise price.

Stock Options

     In September 1991, in order to attract and retain persons necessary for the
success of the Company, the Company adopted a stock option plan (the "Plan")
which covers up to 375,000 of the Company's Common Shares. Pursuant to the Plan,
officers, Directors, consultants and key employees of the Company are eligible
to receive incentive and/or non-incentive stock options. At June 30, 1997,
options to purchase 200,250 shares were outstanding under this plan at $ .50 to
$4.33 per share and 174,750 options had been exercised or cancelled.

     In March 1996, the Board of Directors approved the 1996 Employee Incentive
Stock Option Plan covering an aggregate of 450,000 common shares of the Company
and a 1996 Outside Directors Stock Option plan covering an aggregate of
1,125,000 common shares of the Company. The Board then granted options to
acquire 120,000 shares at prices of $4.00 and $6.00 under the Employee Incentive
Stock Option Plan and options to acquire 778,500 shares at a price of $.73 under

the Outside Directors Plan. At June 30, 1997, no options under either of these
plans had been exercised. The

                                       19

options are exercisable for 10 years. Both of these Plans and the transactions
under which options to acquire 898,500 shares were granted were ratified and
approved at the annual meeting of shareholders on February 19, 1997. Since the
exercise price of the granted options was less than the market price of the
Company's stock on February 19, 1997, this resulted in a non-cash compensation
charge in the amount of $4,544,600, of which $185,000 was recorded during the
fourth quarter of fiscal 1997.

     The Plans are administered by the Board of Directors with the right to
designate a committee. The selection of participants, allotments of shares,
determination of price and other conditions relating to options are determined
by the Board of Directors, or a committee thereof, in its sole discretion.
Incentive stock options granted under the Plans are exercisable for a period of
up to ten years from the date of grant at any exercise price which is not less
than the fair market value of the Common Shares on the date of the grant, except
that the term of an incentive stock option granted under the Plans to a
shareholder owning more than 10% of the outstanding Common Shares may not exceed
five years and its exercise price may not be less than 110% of the fair market
value of the Common Shares on the date of grant.

Compliance with Section 16(a) of the Securities Exchange Act

     Section 16(a) of the Securities and Exchange Act of 1934 requires the
Company's executive officers, Directors and persons who own more than ten
percent of a registered class of the Company's equity securities ("Reporting
Persons") to file reports of ownership and changes in ownership on Forms 3, 4,
and 5 with the Securities and Exchange Commission (the "SEC"), the Boston Stock
Exchange, and the National Association of Securities Dealers, Inc. (the "NASD").
These Reporting Persons are required by SEC regulation to furnish the Company
with copies of all Forms 3, 4 and 5 they file with the SEC and NASD. Based
solely on the Company's review of the copies of the forms it has received, the
Company believes that all Reporting Persons complied on a timely basis with all
filing requirements applicable to them with respect to transactions during
fiscal year 1997.

Item 11.  Security Ownership of Certain Beneficial
          Owners and Management.

     The following table sets forth as of July 31, 1997 certain information with
regard to ownership of the Company's Common Shares by (I) each beneficial owner
of 5% or more of the Company's Common Shares; (ii) each Director and nominee for
Director; (iii) each executive officer named in the "Summary Compensation Table"
below; and (iv) all executive officers and Directors of the Company as a group.
Unless otherwise stated, the persons named in the table have sole voting and

by them.

                         Report of Independent Auditors

The Board of Directors and Stockholders
Misonix Inc. and Subsidiaries

We have audited the accompanying consolidated balance sheet of Misonix, Inc. and
Subsidiaries (the "Company") as of June 30, 1997, and the related consolidated
statements of income, stockholders' equity, and cash flows for each of the two
years in the period then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Misonix, Inc. and
Subsidiaries at June 30, 1997, and the consolidated results of their operations
and their cash flows for each of the two years in the period then ended, in
conformity with generally accepted accounting principles.

                   Notes to Consolidated Financial Statements



1.   Basis of Presentation, Organization and Business, and Summary of
     Significant Accounting Policies

Basis of Presentation

The consolidated financial statements of Misonix, Inc. ("Misonix") include the
accounts of Misonix, its 84.05% owned subsidiary, Labcaire Systems, Ltd.
("Labcaire"), and its 100% owned subsidiary, Misonix, Ltd. (collectively, the
"Company"). All significant intercompany balances and transactions have been
eliminated.

Organization and Business

Misonix was incorporated under the laws of the State of New York on July 31,
1967 and its principal revenue producing activities, from 1967 to date, have
been the manufacture and distribution of proprietary ultrasound equipment for
scientific and industrial purposes and environmental control equipment for the
abatement of air pollution. Misonix's products are sold worldwide. In December
1995 and October 1996, the Company entered into licensing agreements to further
develop two of its medical devices (see Note 13). Sales of these medical
devices, which were made to one customer, were $5,217,124 and $0 during the
years ended June 30, 1997 and 1996, respectively. Amounts receivable from this
customer were approximately $414,000 and $0 at June 30, 1997 and 1996,
respectively.

Labcaire, which began operations in February of 1992, is located in the United
Kingdom, and its core business is the innovation, design, manufacture, and
marketing of air handling systems for the protection of personnel, products and
the environment from airborne hazards. Net sales to unaffiliated customers, net
income and total assets related to Labcaire as of and for the year ended June
30, 1997 were approximately $5,470,000, $232,000 and $2,565,000, respectively.
For the year ended June 30, 1996, these amounts were approximately $4,712,000,
$369,000 and $2,263,000, respectively.

Misonix Ltd. was incorporated in the United Kingdom on July 19, 1993 and its
operations since inception have been insignificant to the Company.

Cash and Cash Equivalents

The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.

                   Notes to Consolidated Financial Statements


1.   Basis of Presentation, Organization and Business, and Summary of
     Significant Accounting Policies (continued)

Investments Held to Maturity

The Company's investments, maturing at various dates through June 1998, consist
primarily of U.S. Government Treasury Bills and Notes and are valued at
amortized cost which approximates market. In accordance with the provisions of
Financial Accounting Standards Board (FASB) Statement No. 115, "Accounting for
Certain Investments in Debt and Equity Securities," the Company classifies its
investments as held-to-maturity as the Company has both the intent and ability
to hold these securities until maturity. The Company's investment policy gives
primary consideration to safety of principal, liquidity and return. At June 30,
1997 and 1996, unrealized gains on held-to-maturity marketable securities were
immaterial.

Concentration of Credit Risk

The Company's operations are located in New York and Clevedon, England. The
Company's policy is to review its customers' financial condition prior to
extending credit and, generally, collateral is not required. At June 30, 1997,
the Company's accounts receivable with customers outside the United States was
approximately $1,330,844 of which approximately $1,185,820 related to its
Labcaire operations. Where necessary, the Company utilizes letters of credit on
foreign or export sales. Credit losses relating to both domestic and foreign
customers have historically been minimal and within management's expectations.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market.

Property and Equipment

Property and equipment are recorded at cost. Depreciation of property and
equipment is provided using the straight-line method over the estimated useful
lives ranging from 3 to 10 years. Capital lease equipment and leasehold
improvements are amortized over the life of the lease or the useful life of the
related asset, whichever is shorter.

Long-Lived Assets

The Company periodically reviews the carrying value of its long-lived assets in

                                       F-8

determining the ultimate recoverability of their unamortized values using future
undiscounted cash flow analyses. Such a review has been performed by management
and does not indicate an impairment of such assets.

Revenue Recognition

Sales are recognized upon shipment of products. Fees from exclusive license
agreements are recognized ratably over the terms of the respective agreements.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the
net assets acquired in connection with the Company's acquisition of 84.05% of
the common stock of Labcaire. The goodwill is being amortized by the
straight-line method over its estimated useful life of 25 years. The carrying
value of such costs is reviewed by management to determine whether an impairment
may have occurred. If this review indicates that such costs, or a portion
thereof, will not be recovered, as determined based on the estimated
undiscounted cash flows of Labcaire over the remaining amortization period, the
carrying value of these costs will be reduced by the estimated shortfall of cash
flows. Such a review has been performed by management and does not indicate an
impairment of such assets.

Income Taxes

The Company accounts for income taxes under the liability method in accordance
with FASB Statement No. 109, "Accounting for Income Taxes." Under this method,
deferred tax assets and liabilities are determined based on differences between
financial reporting and tax bases of assets and liabilities and are measured
using the enacted tax rates and laws that will be in effect when the differences
are expected to reverse.

Net Income Per Common and Common Equivalent Share

Net income per common and common equivalent share is based on the weighted
average number of common shares outstanding plus dilutive common share
equivalents, retroactively adjusted for the effect of a subsequent stock split
(see Note 7).

In February 1997, the FASB issued Statement No. 128, "Earnings Per Share"
(Statement 128), which is effective for both interim and annual financial
statements for periods ending

                                       F-9

     Significant Accounting Policies (continued)

after December 15, 1997. At that time, the Company will be required to change
the method currently used to compute earnings per share and to restate all prior
periods. Under the new requirements for calculating basic earnings per share,
the dilutive effect of stock options will be excluded. The impact of adopting
Statement 128 is not expected to be material.

Foreign Currency Translation

The Company follows the policies prescribed by FASB Statement No. 52 for
translation of the financial results of its foreign subsidiaries. Accordingly,
assets and liabilities are translated at the foreign currency exchange rate in
effect at the balance sheet date. Results of operations are translated using the
weighted average of the prevailing foreign currency rates during the fiscal
year. Stockholders' equity accounts are translated at historical exchange rates.
Gains and losses on foreign currency transactions are recorded in other income
and expense.

Research and Development

All research and development expenses related to the Company's products are
expensed as incurred and are included in operating expenses.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amount of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates.

Stock-Based Compensation

In October 1995, the FASB issued Statement No. 123, "Accounting for Stock-Based
Compensation" ("Statement 123") which the Company adopted in the fiscal year
ended June 30, 1997. The new standard defines a fair value method of accounting
for the issuance of stock options and other equity instruments. Under the fair
value method, compensation cost is measured at the stock options' grant date
based on the fair value of the stock option award and is recognized over the
service period, which is usually the

vesting period. Pursuant to Statement 123, companies are encouraged, but not
required, to adopt the fair value method of accounting for employee stock-based
transactions.

Companies are also permitted to continue to account for such transactions under
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB 25") but are required to disclose in a note to the financial
statements pro forma net income and per share amounts as if the Company had
applied the new method of accounting. Statement 123 also requires increased
disclosures for stock-based compensation arrangements.

The Company has elected to continue to account for such transactions under APB
25 and to provide the pro forma information required under Statement 123 (see
Note 8).

2.   Inventories

Inventories are summarized as follows:

Certain of the leases provide for renewal options and the payment of real estate
taxes and other occupancy costs.

Rent expense for all operating leases was approximately $308,000 and $282,000
for the years ended June 30, 1997 and 1996, respectively.

7.   Stockholders' Equity

On September 9, 1997, the Board of Directors of the Company declared a
three-for-two stock split payable to the shareholders of record on October 10,
1997. All common stock data and per share data in the accompanying consolidated
financial statements, and notes thereto, give retroactive effect to this stock
split.


In January 1992, the Company completed an initial public offering of 2,400,000
shares of its common stock and 2,760,000 warrants to purchase 2,760,000 shares
of its common stock at $5.20 per share, for $8,686,024, net of expenses. On
February 3, 1997,

                   Notes to Consolidated Financial Statements


Stockholders' Equity (continued)

1,093,692 of the previously issued warrants were exercised and a like number of
common shares were issued. The balance of these warrants expired. As a result of
the exercise, the Company received proceeds of $5,655,924, net of expenses of
approximately $31,000.

Also, in connection with this initial public offering, the Company granted the
underwriters a right through January 1997 to acquire an additional 240,000
shares of common stock at an exercise price of $7.15 per share and warrants to
acquire 240,000 shares of common stock in similar form to the public offering
warrants, but at an exercise price of $8.58 per share. In January 1997, this
arrangement was modified and, in leiu of the foregoing, the holders of the
underwriters' rights received the right to purchase 240,000 shares of common
stock at $ .67 per share which, by cashless purchase, resulted in the issuance
of 210,462 shares, and warrants to acquire an additional 240,000 shares of
common stock at a price of $6.00 per share, exerciseable through the close of
business on May 31, 1998.

In connection with a private placement which occurred in October 1991,
redeemable warrants entitling the holders the right to purchase 150,000 shares
of common stock at $5.20 were issued. These warrants expired in February 1997.

8.   Stock Based Compensation Plans

In September 1991, the Board of Directors adopted and, in October 1991, the
shareholders approved, the 1991 Stock Option Plan (the "Option Plan"). The
Option Plan provides for the granting of, at the discretion of the Board of
Directors, options that are intended to qualify as incentive stock options
("Incentive Stock Options") within the meaning of Section 422A of the Internal
Revenue Code of 1986, as amended (the "Code") to certain employees and options
not intended to so qualify ("Nonqualified Stock Options") to employees,
consultants and directors. The total number of shares of Common Stock for which
options may be granted under the Option Plan is 375,000 shares.

In March 1996, the Board of Directors adopted the 1996 Employee Incentive Stock
Option Plan covering an aggregate of 450,000 common shares of the Company and a
1996 Outside Directors Stock Option plan covering an aggregate of 1,125,000
common shares of the Company. The Board then granted options to acquire 120,000

shares at prices of $4.00 and $6.00 under the 1996 Employee Incentive Stock
Option Plan and options to acquire 778,500 shares at a price of $.73 under the
1996 Outside Directors Plan. Both of these Plans and the transactions under
which options to acquire 898,500 shares were granted were ratified and approved
at the annual meeting of shareholders on February 19, 1997. During the period
between the dates of grant by the Board and the

shareholder approval, the Company's market price per share increased thereby
causing the Company to be required to record a non-cash compensation charge in
the amount of $4,544,600, of which $185,000 was recorded during the fourth
quarter of fiscal 1997.

The exercise price of all stock options granted under the Plans must be at least
equal to the fair market value of such shares on the date of grant. With respect
to any participant who owns stock possessing more than 10% of the voting rights
on the Company's outstanding capital stock, the exercise price of any incentive
stock option must be not less than 110% of the fair market value on the date of
grant. The maximum term of each option is ten years. Options shall become
exercisable at such time and in such installments as the Board shall provide in
the terms of each individual option.

The Company has elected to follow APB 25 in accounting for its stock options
because, as discussed below, the alternative fair value accounting provided for
under Statement 123 requires use of option valuation models that were not
developed for use in valuing such stock options. Under APB 25, because the
exercise price of the Company's stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

Proforma information regarding net income per share is required by Statement
123, and has been determined as if the Company has accounted for its stock
options under the fair value method of that Statement. The fair value for these
options was estimated at the date of grant using a Black-Scholes option pricing
model with the following weighted average assumptions risk-free interest rate of
6.36 %; no dividend yields; volatility factor of the expected market price of
the Company's common stock of 93.7%; and a weighted-average expected life of the
options of 5 years at June 30, 1997 and 1996.

The Black-Scholes option valuation model was developed for use in estimating
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's stock options have characteristics significantly different from
those of traded options, and because changes in the subjective input assumptions

can materially affect the fair value estimate, in management's opinion, the
existing models do not necessarily provide a reliable single measure of the fair
value of its stock options.

As required by Statement 123, the fair value method of accounting has not been
applied to options granted prior to July 1, 1996. As a result, the pro forma
compensation cost may not by representative of that to be expected in future
years.

11. Income Taxes

The Company has available net operating loss carryforwards of approximately
$2,000,000 as of June 30, 1997 which may be used to reduce taxable income in
future years. The utilization of these losses in the future will depend on the
generation of sufficient taxable income prior to the expiration of the net
operating losses. Additionally, based on ownership changes as a result of the
public offering consummated in January 1992 (Note 7), it is expected that the
annual utilization of the otherwise available net operating losses will be
limited by the provisions of Section 382 of the Internal Revenue Code, as
amended. As such, the Company may be restricted as to the utilization of its
pre-fiscal 1992 net operating loss carryforwards.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes.

12.  Acquisition

In prior years, the Company acquired an 81.4% interest in Labcaire Systems,
Ltd., a U.K. company, for $545,169. The total acquisition cost exceeded the fair
value of the net assets acquired by $241,299, which is being amortized over 25
years. The balance of the capital stock of Labcaire is owned by four executives
of Labcaire who had the right, under the original purchase agreement (the
"Agreement"), to require the Company to repurchase such shares at a price equal
to its pro rata share of 8.5 times Labcaire's earnings, before interest, taxes
and management charges for the preceding fiscal year.

In June 1996, this Agreement was amended and each of the four directors agreed
to sell one-seventh of his total holding of Labcaire shares to the Company in
each of the next seven consecutive years, commencing with fiscal year 1996. The
price to be paid by the Company for these shares is based on the formula
outlined in the original Agreement. Pursuant to the Agreement, 9,284 shares
(2.65%) of Labcaire common stock was purchased by the Company in October 1996
for (pound)62,388 (approximately $102,100) representing the fiscal 1996 buy-back
portion, and 9,286 shares (2.65%) of Labcaire common stock will be purchased by

the Company in October 1997 for (pound)70,666 (approximately $114,500)
representing the fiscal 1997 buy-back portion. The cost of these purchases of
Labcaire common stock has been recorded as goodwill.

13.  Licensing Agreements For Medical Technology

In December 1995, the Company entered into a licensing agreement with Medical
Device Alliance, Inc. ("MDA"), for a ten year period, covering the further
development and commercial exploitation of the Company's medical technology
relating to soft tissue removal. This agreement primarily focuses on the
Company's patent for a liposuction apparatus granted in May 1995 and its 510(K)
approval from the United States Food and Drug Administration to market and sell
a device for ultrasonic soft tissue removal. The licensing agreement gives MDA
exclusive world-wide marketing and sales rights for the device, with
manufacturing to be performed by the Company. Pursuant to the license agreement,
the Company received $500,000 in licensing fees (which is being recorded as
income over the term of the agreement) and will receive royalties based upon net
sales of such products. Also as part of the agreement, the Company was
reimbursed for certain pre-marketing costs and a maximum of $30,000 per month
(from September 1995 to January 1997) for product development expenditures (as
defined in the agreement). The amount of reimbursements for the years ended June
30, 1997 and 1996 were $127,487 and $320,363, respectively.

In October 1996, the Company entered into a License Agreement with United States
Surgical Corporation ("USS") covering the further development and commercial
exploitation of the Company's medical technology relating to ultrasonic cutting,
which uses high frequency sound waves to coagulate and divide tissue for both
open and laproscopic surgery. The license agreement gives USS exclusive
world-wide marketing and sales rights for this technology. The Company received
$100,000 under the option agreement preceding the license agreement. This amount
was recorded into income in fiscal 1997. Under the license agreement, the
Company is entitled to receive aggregate fees of approximately $500,000, subject
to attaining certain milestones over the term of the agreement, plus royalties
based upon net sales of such products. As of June 30, 1997, the Company has
received $275,000 under this license agreement. This amount is being recorded as
income over the term of the agreement.

The Company has settled a dispute with two individuals who claimed that they,
together with the Company's founder, were joint inventors of the technology
covered under the Patent for Liposuction Method and Apparatus. As a result, the
two individuals have reconfirmed their assignment of the patent rights to the
Company in exchange for 5% of all net sales and royalties received by the
Company from this technology, including those received from the MDA license.

Thousand Dollars ($25,000.00) if Misonix develops and delivers to USSC one

clamping/sealing probe/tip and one hook/cutting probe/tip, by September 10,
1996, and (b) Fifty Thousand Dollars ($50,000.00) if Misonix develops and
delivers to USSC ten damping/sealing probes/tips and five hook/cutting
probes/tips, by September 15;1996. Notwithstanding anything to the contrary
contained in this Agreement or in any of the Attachments thereto, the Working
Prototypes to be developed and delivered by Misonix are to be development and
evaluation models oniy and not suitable necessarily for clinical tests of such
Working Prototypes.

     ARTICLE 5 - EVALUATION OF PROTOTYPE AND OPTION

     5.1 For a ninety (90) day period following receipt by USSC of a Working
Prototype, USSC shall be permitted to evaluate and test the same throughout the
world (the "Exclusive Evaluation Period"). In connection therewith, Misonix
shall promptly answer questions USSC may have related thereto and provide to
USSC test results, analysis and other Know-How in Misonix's possession or
control which may be useful in connection with USSC's evaluation. Without
limiting or being limited by the foregoing, the Exclusive Evaluation Period may
be extended by USSC, at its option, for one additional thirty (30) day period in
the event of any one or more of the following: (a) USSC requires, in the
reasonable opinion of its counsel, additional time to evaluate the intellectual
property rights issues related to the Product or Know-How, or (b) USSC requires,
in its reasonable judgment, additional time to evaluate the Product or the
Know-How 


                                       5


<PAGE>



     5.2 Misonix hereby grants to USSC, and USSC hereby accepts from Misonix, an
exclusive paid up option (the "License Option") exercisable in USSC's sole and
absolute discretion to acquire the license and other rights set forth in Exhibit
A (the "Exhibit A License") in the Field. The License Option shall be subject to
exercise by USSC by notice to Misonix at any time prior to the end of such
ninety (90) day period or such one hundred and twenty day (120) period referred
to in 5.1, as the case may be, that USSC is exercising the License Option. Upon
delivery of such notice and the cash consideration required to be delivered by
USSC, the license in the form of Exhibit A shall be deemed executed by, binding
upon and enforceable against the parties thereto covering the Exhibit A License
Field. However, within thirty (30) days thereafter, the parties thereto shall
execute copies of the Exhibit A License for their records. Failure to so execute
copies of the Exhibit A License for the records of the parties shall not affect
the effectiveness or enforceability of the provisions thereof. 

     5.3 The provisions of this Article 5 shall survive termination of this
Agreement.

     ARTICLE 6 - PROPRIETARY INFORMATION

     6.1 USSC hereby covenants and agrees that it will not, directly or

indirectly, disclose, either during or for five (5) years subsequent to the
Term, any Confidential Information of Misonix to any other person or entity,
except to its attorneys and accountants as may be required in connection with
this Agreement who have been or will be instructed to maintain its
confidentiality and to third parties who shall execute binding written
agreements requiring such parties not to disclose Confidential Information
disclosed to them by USSC. In addition to the foregoing, USSC hereby covenants
and agrees that it will not, directly or indirectly, during the term of this
Agreement, use the Working Prototype or any Know-How developed by Misonix except
as permitted by this Agreement. USSC further covenants and agrees that,
following termination of this Agreement, except in the event it has exercised
the License Option and entered into the License referred to herein (and as
permitted by such License), USSC shall not use, directly or indirectly, the
Working Prototype or any Know-How disclosed by Misonix for five (5) years
thereafter to the extent and for so long as it constitutes Misonix Confidential
Information.

     6.2 Misonix hereby covenants and agrees that it will not, directly or
indirectly, disclose during or for five (5) years subsequent to the Term, any


                                       6


<PAGE>



Confidential Information of USSC to any other person or entity, except to
Misonix's attorneys and accountants as may be required in connection with this
Agreement who have been or will be instructed to maintain its confidentiality.

     6.3 It is not intended by this Article 6 that USSC or Misonix shall be
required to obtain specific written commitments in relation to this Agreement
from materials and/or component suppliers where only specifications are
disclosed to said materials and/or component suppliers by USSC and by Misonix.

     6.4 For purposes of this Agreement, "Confidential Information" shall mean
verbal and written disclosures from Misonix, on the one hand, or USSC, on the
other hand, (the "Discloser") to the other party (the "Disclosee"), which
concern the Discloser including, without limitation, information which concerns
the Discloser's business, operations, products or research and development
efforts, or which concern the Products or Know-How, but shall not include
information which: (a) at the time of disclosure is published or otherwise
becomes a part of the public domain through no fault of Disclosee (but only
after, and only to the extent that, it is published or otherwise becomes a part
of the public domain); (b) Disclosee can show was known to it at the time of
disclosure, free of restriction; (c) has been or hereafter is disclosed to
Disclosee without any obligation of confidentiality by a third party who is in
lawful possession of such information and has the right to disclose it to
Disclosee; (d) has been or hereafter is disclosed by Discloser to a third party
free of any obligations of confidentiality; (e) was independently developed by
the Disclosee, or (f) is disclosed by Disclosee pursuant to the order or
requirement of a court, administrative agency or other governmental body,

provided that the Disclosee promptly informs the Discloser of its intent to make
such disclosure, takes all reasonable steps to limit such disclosure and does

connection with this Agreement who have been or will be instructed to maintain
its confidentiality and to third parties who shall execute binding written
agreements

<PAGE>

Confidential Information of Misonix without obtaining such written agreements in
connection with any regulatory and patent filings involving or relating to
matters covered by this Agreement.

confidentiality and, to the extent necessary in the reasonable opinion of
Misonix's counsel, to be publicly disclosed and/or included in any filings
required under applicable securities laws involving or relating to matters
covered by this Agreement, provided, that in any such event, Misonix shall
advise USSC thereof as far in advance as is reasonably possible under the
circumstances to permit USSC to comment thereon and to take any action which it
may deem appropriate to limit the scope and extent of such disclosure.

     6.3 It is not intended by this Article 6 that USSC or Misonix shall be
required to obtain specific written commitments in relation to this Agreement
from materials and/or component suppliers where only specifications are
disclosed to said materials and/or component suppliers by USSC or Misonix.

     6.4 For purposes of this Agreement, "Confidential Information" shall mean
verbal and written disclosures from Misonix, on the one hand, or USSC, on the
other hand, (the "Discloser") to the other party (the "Disclosee"), which

the Discloser's business, operations, products or research and development
efforts, or which concern the Products or Know-How, but shall not include
information which: (a) at the time of disclosure is published or otherwise
becomes a part of the public domain through no fault of Disclosee (but only
after, and only to the extent that, it is published or otherwise becomes a part
of the public domain); (b) Disclosee can show was known to it at the time of
disclosure, free of restriction; (c) has been or hereafter is disclosed to
Disclosee without any obligation of confidentiality by a third party who is in
lawful possession of such information and has the right to disclose it to
Disclosee; (d) has been or hereafter is disclosed by Discloser to a third party
free of any


                                       8


<PAGE>



obligations of confidentiality; (e) is independently developed by Disclosee; or
(f) is disclosed by Disclosee pursuant to the order or requirement of a court,
administrative agency or other governmental body, provided that the Disclosee
promptly informs the Discloser of its intent to make such disclosure, takes all
reasonable steps to limit such disclosure and does not inhibit the Discloser in
taking whatever lawful steps the Discloser considers necessary to attempt to
preserve the confidentiality of such information. Disclosures made to Disclosee
by Discloser which are specific shall not be deemed to be within the foregoing
exceptions merely because they are embraced by general disclosures in the public
domain or in the possession of Disclosee. The existence, terms and conditions of
this Agreement shall be deemed Confidential Information of the parties to this
Agreement.

     6.5 The parties hereby acknowledge and agree that any breach of this
Article 6 by Misonix, on the one hand, or USSC, on the other hand, would likely
cause irreparable injury to the other party and that such other party?5 remedy
at law for any such breach would be inadequate. Accordingly, the parties agree
that, in addition to any other remedies provided for herein or otherwise
available at law, temporary and permanent injunctive relief and other equitable
relief may be granted in any action, suit or proceeding which may be brought by
either party to enforce the provisions of this Article 6 without the necessity
of proof of actual damage. Each party agrees promptly to seek temporary and
permanent injunctive relief against any of its directors, officers, employees or
consultants who breach the aforesaid obligations with respect to any matter
relating to this Agreement.

     6.6 The provisions of this Article 6 shall survive termination of this
Agreement for three (3) years.

employees of USSC or other persons or entities or retained by USSC during the

or provide technical assistance or advice to any third person or entity with
respect to the design, development, manufacture or sale of any Product or
similar instrument, device, or system without USSC's prior written consent in
USSC's sole and absolute discretion. The foregoing shall not be construed to
prohibit Misonix from engaging in its own development of Products and Know-How,
subject to the rights of USSC with respect thereto as set forth in this
Agreement. In addition, Misonix shall have the right to continue its undertaking
with Medical Device Alliance, Inc. ("MDA") in connection with the development of
devices used in ultrasonic soft tissue aspiration and related endeavors provided
it does not involve the Technology or violate Article 6 above.

     8.2 The parties acknowledge and agree that any breach of this Article 8 by
Misonix would likely cause irreparable injury to USSC and that USSC's remedy at
law for any such breach would be inadequate. Accordingly, the parties agree
that, in addition to any other remedies provided for herein or otherwise
available at law, temporary and permanent injunctive relief and other equitable
relief may be granted in any action, suit or proceeding which may be brought by
USSC to enforce any provision of this Article 8 without the necessity of proof
of actual damage.

Misonix had actual knowledge on or prior to the date of the Development and
Option Agreement of a claim by a third party for infringement, USSC shall have
no obligation to defend or indemnify Misonix. USSC shall at all times keep
Misonix apprised of the status of any such claim, action, suit or proceeding and
allow Misonix to participate in all major decisions regarding the conduct of
such litigation including without limitation any decision to settle or pursue
the case to trial, provided, however, that USSC shall retain exclusive authority
to make all decisions regarding the conduct of such litigation or the
negotiation and consummation of any settlement.

suit or proceeding pursuant to such award of damages, or to the third party(s),
if any, with whom USSC settles pursuant to this Section 11.5(a), to the extent
required by the terms of such settlement, and pay USSC's legal costs and
expenses as and when billed to USSC in connection with any such claim, action,
suit or proceeding and the balance, if any, of the principal and interest to
Misonix after final determination of and any reduction for all of the foregoing.
Such future Royalties shall be subject to escrow in accordance with this Section
11.5(a).

     (b) Notwithstanding Section 1.5(a) above, in the event that Misonix commits
or has committed any fraud upon USSC in connection with this Agreement or
misrepresentation or breach of warranty of any matter which is the subject of
any of Misonix's representations and warranties contained herein1 in addition to
all other remedies available to it at law or in equity, USSC shall have the
right upon the receipt of any claim or the commencement of any action, suit or
proceeding, by either party hereto or any third party, relating to or


                                       14


<PAGE>



arising gout of such fraud or misrepresentation or breach of warranty, deposit
with a bank escrow agent the payments then due and thereafter becoming due under
the terms of this Agreement. USSC shall instruct such escrow agent to deposit
such payment in an interest-bearing account and to release the same to the third
party(s), if any, awarded damages in such action, suit or proceeding pursuant to
such award of damages or to the third party(s), if any, with whom USSC settles
pursuant to this Section 11.5(b), to the extent required by the terms of such
settlement, and to pay USSC's legal costs and expenses as and when billed to
USSC in connection with any such claim, action, suit or proceeding and the
balance, if any, of the principal and interest to Misonix after final
determination if and any reduction for all of the foregoing, the liability of
Misonix and the Principals for such award, amounts paid in settlement and USSC's
legal costs and expenses shall be up to the entire amount in escrow pursuant to
this Section 11.5(b), plus all future Royalties payable by USSC under this
Agreement. Such future Royalties shall be subject to escrow in accordance with
this Section 11.5(b). Notwithstanding the foregoing, the parties agree that any
such withholding of payments shall not limit the liability of Misonix for

damages in the event of any fraud, misrepresentation or breach of warranty
specified in this Section 11.5(b) or in the event of any other breach of this
Agreement by any of them, and shall not affect any right or license granted to
USSC hereunder or any other provisions of this Agreement or any party's
available remedies.

     11.6 In the event that any claim is asserted against Misonix or USSC, or
any of their respective officers, directors, employees, agents or
representatives, or such person is made a party defendant in any action or
proceeding involving a matter which is the subject of USSC's indemnification and
hold harmless agreement as set forth above, or Misonix becomes the subject of a
claim of infringement against USSC, its Subsidiaries, Affiliates, Sublicensees
or permitted assignees as a result of their manufacture, use or sale of a
Product, then within 10 days of receipt by any Misonix or by USSC of notice of
any such event, and within 7 days of such party's receipt of a written complaint
or other formal pleading regarding any such event, such party shall give the
other party hereto written notice of such claim, action, suit, proceeding,
patent or patent application.

first refusal set forth herein. In accordance with such right of first refusal,

USSC, which may be withheld in its sole and absolute discretion. Prior to
offering or responding to an offer for such sale, license or other transfer,
Misonix hall have complied with all of their respective obligations under this
Agreement to be complied with prior to such offer or response. Prior to any
sale, license or other transfer, Misonix shall obtain a bona ,fide written offer
(the "Outside Offer") from such third party describing the subject of such sale,
licensee or other transfer, the interest to be sold, licensed or otherwise
transferred, and a stated cash consideration at which the third party offers to
acquire, and Misonix desires to sell, license or otherwise transfer, said
interest. After obtaining the Outside Offer, Misonix shall promptly, and before
accepting the Outside Offer, deliver to USSC an offer, irrevocable for forty
five (45) days from its receipt, to sell, license or otherwise transfer to USSC
the interest which is the subject of the Outside Offer for the cash
consideration and upon all other terms and conditions stated in the Outside
Offer. A copy of the Outside Offer shall accompany the offe# to USSC. If USSC
accepts such offer within said forty five (45) days, Misonix shall transfer the
relevant interest to USSC pursuant to the terms and conditions of such offer.

construed to limit the right of Misonix (or to give USSC any rights with respect

of Misonix with or into any other firm, corporation or entity, but the rights of
USSC set forth in this Agreement shall survive any such sale, merger or
combination. Notwithstanding, Misonix shall not have the right, and nothing in
this Section 12.1 or anything else in this Agreement shall be construed to
authorize Misonix


                                       16


<PAGE>



to sell license or otherwise transfer any of the license or other rights
granted to USSC under this Agreement.

     12.2 The parties acknowledge and agree that any breach of this Article 12
by Misonix would likely cause irreparable injury to USSC and that USSC's remedy
at law for any such breach would be inadequate. Accordingly, the parties agree
that in addition to any other remedies provided for herein or otherwise
available at law, temporary and permanent injunctive relief and other equitable
relief may be granted in any action, suit or proceeding which may be brought by
USSC to enforce any provision of this Article 12 without the necessity of proof
of actual damages.

notify USSC in writing of the proposed project and proposed expenditures in
reasonable detail and USSC shall have a period of ten business days within which
to approve or reject the same, in writing, in USSC's sole discretion. If such
proposed expenditures are approved by USSC, the acceptance by USSC shall be
accompanied by a check to Misonix in the approved amount of the agreed upon
Development Funding. If such proposed expenditures are rejected, such rejection
shall be reasonably detailed. Misonix shall maintain books and records
concerning Development Funding during the term of this Agreement and for five
(5) years thereafter. USSC and its representatives shall have the right to
review such books and records during normal business hours upon prior notice.

     occurring during the term of this Agreement; and

          (b)

               (i) if USSC terminates this Agreement under Section 14.1(c) and
          on such termination date (the "Unilateral Termination Date") neither
          Misonix nor any Affiliate of Misonix owns or has exclusive license
          rights to a issued patent covering the Product, which patent is
          unexpired and has not been held invalid by a court of competent
          jurisdiction from which no appeal can be taken, an amount equal to
          five percent (5%) of Net Sales of a Product for a period of five (5)

                                        5


<PAGE>



               (ii) If USSC terminates this Agreement under Section 14.1(c) and
          on the Unilateral Termination Date either Misonix or any Affiliate of
          Misonix owns or has exclusive license rights to a issued patent

          exceed five years, which remain on the life of a patent which (aa) as
          of the Unilateral Termination Date either Misonix or any Affiliate of
          Misonix owns or under which either Misonix or any Affiliate of Misonix
          has exclusive license rights, and (bb) which patent covers the

          in no event extend longer than five (5) years from the Unilateral
          Termination Date.

     4.5 The Royalty shall accrue as and when a sale subject to a royalty is
recorded by USSC in accordance with Section 1.1(e), and shall be paid to Misonix
quarterly on or before forty-five (45) days after each calendar quarter during
which a sale is recorded.


     ARTICLE 5 - PAYMENT, REPORTING AND RECORDS

     5.1 USSC agrees to deliver quarterly written reports to Misonix for each
three (3) month period ending on the last day of the months of March, June,
September, and December of each year, within forty-five (45) days after the end
of each such period. The report shall set forth the number of Products sold by
USSC, its Subsidiaries, Affiliates, Sublicensees and permitted assignees during
the immediately preceding calendar quarter, Net Sales applicable to all such
Products, and the amount of License Fees and Royalties (and including any
catchup adjustments) then payable to Misonix. All information contained in such

<PAGE>



Agreement. USSC shall maintain records in sufficient detail and, upon reasonable
notice, allow any independent certified public accounting firm of nationally
recognized standing, appointed by Misonix, and reasonably acceptable to USSC, to
examine its consolidated books and records, and the books and records of its
Sublicensee~" and permitted assignees pertaining to the Products. Such
examinations shall occur on or after February 15 of any calendar year (or, if
Misonix appoints for purposes of such examination the accounting firm employed
by USSC to conduct its regular annual audit, prior to February 15,) only during
business hours, and not more than once a year, and shall be solely for the
purpose of verifying the calculation of License Fees and Royalties due under
this Agreement. A final such examination may occur once during the year
immediately succeeding termination of this Agreement. In the event Misonix
appoints for the purpose of examining USSC's consolidated books and records the
accounting firm employed by USSC to conduct its regular annual audit, and if the
examination provided for herein is performed at substantially the same time as
such regular annual audit, the fees and expenses of the accounting firm
performing the examination shall be borne by USSC. In any other event, the fees
and expenses of the accounting firm performing the examination shall be borne by
Misonix. Unless written objection is made by Misonix and delivered to USSC
within thirty (30) days after completion of such examinations, the calculation
of License Fees and Royalties paid by USSC prior to the date of such examination
shall be final and binding on the parties, except insofar as adjusted or
corrected as a result of USSC's regular annual audit. It is understood that USSC
shall not be required to furnish or permit the examination of the identities, at
any time, of customers or prices or other information as to specific sales. Any
information provided to Misonix or its accountants pursuant hereto shall be
treated as USSC's Confidential Information subject to Article 6.

     ARTICLE 6 - PROPRIETARY INFORMATION


     6.1 USSC hereby represents and warrants that it will not, directly or
indirectly, disclose, either during or for three (3) years subsequent to the
term of this Agreement, any Confidential Information of Misonix to any other
person or entity, except to its attorneys and accountants as may be required in
connection with this Agreement who have been or will be instructed to maintain
its confidentiality and to third parties who shall execute binding written
agreements requiring such third parties not to disclose Confidential Information
disclosed to

                                        7


<PAGE>



them by USSC. Notwithstanding the foregoing, USSC shall have the right to use
Confidential Information of Misonix without obtaining such written agreements in
connection with any regulatory and patent filings involving or relating to
matters covered by this Agreement.

     6.2 Misonix hereby agrees that it will not, directly or indirectly,
disclose during or for three (3) years subsequent to the term of this Agreement,
any Confidential Information of USSC, to any other person or entity, except to
the Misonix's attorneys and accountants as may be required in connection with
this Agreement who have been and will be instructed to maintain its
confidentiality and, to the extent necessary in the reasonable opinion of
Misonix's counsel, to be publicly disclosed and/or included in any filings
required under applicable securities laws involving or relating to matters
covered by this Agreement, provided, that in any such event, Misonix shall
advise USSC thereof as far in advance as is reasonably possible under the
circumstances to permit USSC to comment thereon and to take any action which it
may deem appropriate to limit the scope and extent of such disclosure.

     6.3 It is not intended by this Article 6 that USSC or Misonix shall be
required to obtain specific written commitments in relation to this Agreement
from materials and/or component suppliers where only specifications are
disclosed to said materials and/or component suppliers by USSC or Misonix.

     6.4 For purposes of this Agreement, "Confidential Information" shall mean
verbal and written disclosures from Misonix, on the one hand, or USSC, on the
other hand, (the "Discloser") to the other party (the "Disclosee"), which
concern the Discloser including, without limitation, information which concerns
the Discloser's business, operations, products or research and development
efforts, or which concern the Products or Know-How, but shall not include
information which: (a) at the time of disclosure is published or otherwise
becomes a part of the public domain through no fault of Disclosee (but only
after, and only to the extent that, it is published or otherwise becomes a part
of the public domain); (b) Disclosee can show was known to it at the time of
disclosure, free of restriction; (c) has been or hereafter is disclosed to
Disclosee without any obligation of confidentiality by a third party who is in
lawful possession of such information and has the right to disclose it to
Disclosee; (d) has been or hereafter is disclosed by Discloser to a third party

free of any obligations of confidentiality; (e) is independently developed by
Disclosee; or (f) is

                                        8


<PAGE>



disclosed by Disclosee pursuant to the order or requirement of a court
administrative agency or other governmental body provided that the Disclosee
promptly informs the Discloser of its intent to make such disclosure, takes all
reasonable steps to limit such disclosure and does not inhibit the Discloser in
taking whatever lawful steps the Discloser considers necessary to attempt to
preserve the confidentiality of such information. Disclosures made to Disclosee
by Discloser which are specific shall not be deemed to be within the foregoing
exceptions merely because they are embraced by general disclosures in the public
domain or in the possession of Disclosee. The existence, terms and conditions of
this Agreement shall be deemed Confidential Information of the parties to this
Agreement.

     6.5 The parties hereby acknowledge and agree that any breach of this
Article 6 by Misonix, on the one hand, or USSC, on the other hand, would likely
cause irreparable injury to the other party and that such other party's remedy
at law for any such breach would be inadequate. Accordingly, the parties agree
that, in addition to any other remedies provided for herein or otherwise
available at law temporary and permanent injunctive relief and other equitable
relief may be granted in any action, suit or proceeding which may be brought by
either party to enforce the provisions of this Article 6 without the necessity
of proof of actual damage. Each party agrees promptly to seek temporary and
permanent injunctive relief against any of its directors, officers, employees or
consultants who breach the aforesaid obligations with respect to any matter
relating to this Agreement.

     6.6 The provisions of this Article 6 shall survive termination of this
Agreement for three (3) years. 

     ARTICLE 7 - INVENTIONS

     7.1 All patentable and unpatentable inventions, discoveries and ideas
("Inventions") relating to Products which are made or conceived solely by
employees of USSC or other persons or entities or retained by USSC during the
term of this Agreement shall be the property of USSC. All Inventions which are
made or conceived solely by Misonix or by other persons or entities retained by
Misonix shall be the property of Misonix, but subject to USSC's rights set forth
in this Agreement. All Inventions which are made or conceived by Misonix (and/or
other persons or entities retained by Misonix), on the one hand, and USSC
(and/or other persons or entities retained by USSC), on the other hand, 


                                        9



<PAGE>

forth in this Agreement.

     ARTICLE 8 - NON-COMPETE

     8.1 Misonix agrees that during the term of this Agreement, except as
expressly permitted by this Agreement, it shall not, directly or indirectly,
develop, manufacture, or sell any Product, or similar or related instrument,
device or system, or Know-How to any third person or entity, or to consult with
or provide technical assistance or advice to any third person or entity with
respect to the design, development, manufacture or sale of any Product or
similar instrument, device, or system without USSC's prior written consent in
USSC's sole and absolute discretion. The foregoing shall not be construed to
prohibit Misonix from engaging in its own development of Products and Know-How,
subject to the rights of USSC with respect thereto as set forth in this
Agreement. In addition, Misonix shall have the right to continue its undertaking
with Medical Device Alliance, Inc. ("MDA") in connection with the development of
devices used in ultrasonic soft tissue aspiration and related endeavors provided
it does not involve the Technology or violate Article 6 above.

     8.2 The parties acknowledge and agree that any breach of this Article 8 by
Misonix would likely cause irreparable injury to USSC and that USSC's remedy at
law for any such breach would be inadequate. Accordingly, the parties agree
that, in addition to any other remedies provided for herein or otherwise
available at law, temporary and permanent injunctive relief and other equitable
relief may be granted in any action, suit or proceeding which may be brought by
USSC to enforce any provision of this Article 8 without the necessity of proof
of actual damage.

     ARTICLE 9 - INDEMNIFICATION

     9.1 Subject to the fulfillment by Misonix of its obligations pursuant to
Section 9.2 below, USSC agrees to defend, indemnify and hold harmless Misonix
and each of Misonix's directors, officers, employees, agents, and
representatives, from and against any claims, demands, judgments, executions,
awards, or damages, including reasonable attorney's fees and expenses incurred
by USSC in defending the same, constituting a product liability action or other
action, suit or proceeding arising as a result of the design, manufacture, use
or sale of a Product by USSC, its Subsidiaries, Affiliates, Sublicensees or
permitted assigns. In 

                                       10


<PAGE>

furtherance of the foregoing, USSC shall include Misonix as a covered person on
USSC's product liability insurance in an amount of at least $5,000,000, with
waiver of subrogation. In satisfaction of the foregoing indemnification and hold
harmless agreement, USSC may pay directly to the claimant or plaintiff in any
such claim, action, suit or proceeding, the amount of any award judgement
settlement or recovery, or execution rendered thereon, and may pay to Misonix

and Misonix's directors, officers, employees, agents, and representatives, any
other damages or reasonable expenses sustained by them in defending any such
claim, action, suit or proceeding. USSC shall have the right to conduct the
legal defense, or to enter into any settlement agreement, as it, in its sole
discretion, deems appropriate. Misonix may participate in such action, suit or
proceeding through its own attorneys at their sole cost and expense.

     9.2 In the event that any claim is asserted against Misonix or Misonix's
directors, officers, employees, agents or representatives, or such person is
made a defendant in any action, suit or proceeding involving a matter which is
the subject of USSC's indemnification and hold harmless agreement as set forth
above, then within ten (10) days of such person's receipt of notice of such
event and within seven (7) days of receipt of a complaint or other formal
pleading regarding such event, such persons shall give written notice of such
claim, action, suit or proceeding to USSC, and USSC shall be given an
opportunity to assume the defense and control any settlement on behalf of such
persons. Misonix shall provide their full cooperation to USSC in connection with
the defense of such claim, action, suit or proceeding.

     9.3 Misonix shall provide indemnifications to USSC with respect to product
liability (on any legal theory) actions, suits and proceedings to the same
extent as set forth above in this Article 9 for Products which Misonix may, in
Misonix's discretion, sell or transfer to USSC. For purposes of this Section
9.3, Misonix's collection of royalties hereunder shall not be deemed to
constitute the sale or transfer of Products.

     9.4 The provisions of this Article 9 shall survive termination of this
Agreement.

     ARTICLE 10 - FDA INTERACTION

     10.1 Interaction with the regulatory agencies in any country including, but

<PAGE>


concerning the Products shall be conducted by USSC, and for purposes of any
filings with the FDA concerning the Products USSC shall be the official company
sponsor. In the event of a dispute between USSC and Misonix concerning any
matter relating to interaction with the FDA, USSC shall have final authority to
act as USSC, in its sole discretion, deems appropriate with respect to the
matter in dispute.

     10.2 During the term of this Agreement, Misonix shall, at USSC's request,
assist USSC during FDA interaction concerning the Products; provided that USSC
shall reimburse Misonix for all out-of-pocket expenses, other than attorneys
fees, incurred by Misonix in providing such assistance.

     10.3 Notwithstanding any provision of this Agreement to the contrary, USSC
shall not be obligated to, and shall have no liability to Misonix for failure to

evaluate, develop, test, conduct clinical trials, make, have made, use,
practice, manufacture or have manufactured any Product or practice or use the
Know-How or for failure to seek or pursue any FDA or other regulatory approvals.
USSC shall have the unqualified right, at any time to cease or suspend all
marketing efforts and all efforts to obtain FDA or other regulatory approvals.
Nothing herein shall prevent USSC from setting its own prices for Products or
determining USSC's marketing policies and practices in its sole discretion.

     ARTICLE 11 - PATENT AND TRADEMARK PROSECUTION AND INFRINGEMENT

     11.1 Upon or prior to the date of this Agreement, Misonix shall deliver to
USSC copies of all Patents and Trademarks in its possession or control and all
related documents and correspondence in its possession or control to the extent
not delivered by the date of this Agreement. During the term of this Agreement
and subject to Section 11.3, USSC shall, at its own expense, use reasonable
efforts to obtain and maintain patents and trademark registration based on the
Patents and Trademarks in the United States. USSC shall also assume prosecution
and all future costs incurred and due during the term of this Agreement in
connection with the Patents and Trademarks filed prior to the date hereof set
forth in Schedule 1. Misonix agrees to fully cooperate with USSC in the
preparation, filing and prosecution of all applications for letters patent and
trademark registrations which USSC may in its sole discretion file and prosecute
in the United States and foreign countries in accordance with this Section 11.1,
and in the prosecution of the Patents and Trademarks, and, in connection with


                                       12


<PAGE>

such applications and the Patents and Trademarks, Misonix further agrees to
execute and deliver all documents which USSC may deem necessary or desirable.

     11.2 Misonix, on the one hand, and USSC on the other hand, shall promptly
give written notice to the other of any apparent infringement discovered by it
with respect to any patent or trademark issuing from the Patents and Trademarks.
Such notice shall set forth the facts of the apparent infringement in reasonable
detail. USSC shall have the right to bring or settle, in USSC's sole discretion,
any action, suit or proceeding with respect to such apparent infringement at its
own expense and for its own benefit; provided, however, that after recovery by
USSC of its litigation costs, including reasonable outside attorneys fees, USSC
shall pay to Misonix at the Royalty rate set forth in Article 4 from the amount
actually received by USSC in connection with the settlement or a judgment in
such litigation. In such event, Misonix agrees to cooperate with USSC and to
join in such action, suit or proceeding as a party plaintiff if requested to do
so by USSC and to give USSC all needed information, assistance and authority to
file and prosecute such suit; provided that USSC shall reimburse Misonix for all
out-of-pocket expenses incurred by it in providing such assistance, other than
attorneys' fees and expenses, incurred by Misonix.

     11.3 If USSC or Misonix receives notice of a claim, action, suit or
proceeding by a third party alleging infringement of such third party's rights
in connection with the manufacture, use or sale of a Product by USSC, its

Affiliates, Subsidiaries, Sublicensees or permitted assignees, USSC shall have
the right to conduct the legal defense, and to enter into any disposition with
respect thereto, as USSC in its sole discretion deems desirable. Misonix shall
fully cooperate with USSC in its defense of such infringement claim, provided
that USSC shall reimburse Misonix for all out-of-pocket expenses, other than
attorneys' fees and expenses, incurred by it in providing such cooperation.

     11.4 Subject to the fulfillment by Misonix of its obligations pursuant to
Section 11.6 below, USSC shall defend Misonix against a third party infringement
claim which results from the manufacture, use or sale of a Product by USSC, its
Affiliates, Subsidiaries, Sublicensees or permitted assignees, and indemnify
Misonix against the cost of such defense undertaken by USSC, including
reasonable attorneys' fees and court costs, and damages awarded or amounts paid
in settlement in any such action. However, notwithstanding the foregoing, if
Misonix had actual knowledge on or prior to the date of the Development and

                                       13


<PAGE>


Option Agreement of a claim by a third party for infringement, USSC shall have
no obligation to defend or indemnify Misonix. USSC shall at all times keep
Misonix apprised of the status of any such claim, action, suit or proceeding and
allow Misonix to participate in all major decisions regarding the conduct of
such litigation including without limitation any decision to settle or pursue
the case to trial, provided, however, that USSC shall retain exclusive authority
to make all decisions regarding the conduct of such litigation or the
negotiation and consummation of any settlement.

     11.5 The cost of USSC's defense of any claim referred to in Section 11.4
above, and any damages awarded or any amount paid in settlement or other
disposition of such claim, shall be set off against and, thereby, reduce, as set
forth in this Section 11.5, fifty percent (50%) the outstanding and future
Royalties due from USSC to Misonix.

     (a) Except with respect to circumstances set forth in Section 11.5(b)
during the pendency of any such claim, action, suit or proceeding, USSC shall
have the right to deposit with a bank escrow agent the payments then due and
thereafter becoming due under the terms of this Agreement. USSC shall instruct
such escrow agent to deposit such payments in an interest-bearing account and to
release the same to the third party(s), if any, awarded damages in such action,
suit or proceeding pursuant to such award of damages, or to the third party(s),
if any, with whom USSC settles pursuant to this Section 11.5(a), to the extent
required by the terms of such settlement, and pay USSC's legal costs and
expenses as and when billed to USSC in connection with any such claim, action,
suit or proceeding and the balance, if any, of the principal and interest to
Misonix after final determination of and any reduction for all of the foregoing.
Such future Royalties shall be subject to escrow in accordance with this Section
11.5(a).

     (b) Notwithstanding Section 11.5(a) above, in the event that Misonix
commits or has committed any fraud upon USSC in connection with this Agreement

or misrepresentation or breach of warranty of any matter which is the subject of
any of Misonix 's representations and warranties contained herein, in addition
to all other remedies available to it at law or in equity, USSC shall have the
right upon the receipt of any claim or the commencement of any action, suit or
proceeding, by either party hereto or any third party, relating to or arising

refusal, Misonix hereby agrees that during the term of this Agreement and except
pursuant to this Article 12, it shall not, directly or indirectly transfer, by
sale, license or otherwise, to any third person or entity, a) any interest in
any of the Patents and Trademarks, a Product or the Know-How. No such sale,

the interest which is the subject of the Outside Offer for the cash
consideration and upon all other terms and conditions stated in the Outside
Offer. A copy of the Outside Offer shall accompany the offer to USSC. If USSC
accepts such offer within said forty five (45) days, Misonix shall transfer the

6 and 10, Misonix may transfer such interest to the third party who made the
Outside Offer in accordance with its terms and conditions during the sixty (60)
days immediately following expiration of the aforesaid forty-five (45) day
period. Notwithstanding the foregoing, nothing herein contained shall be
construed to limit the right of Misonix (or to give USSC any rights with respect
to any sale of shares of capital stock of Misonix or the merger or combination
of Misonix with or into any~other firm, corporation or entity, but the rights of
USSC set forth in this Agreement shall survive any such sale, merger or
combination. Notwithstanding, Misonix shall not have the right, and nothing in
this Section 12.1 or anything else in this Agreement shall be construed to
authorize Misonix to sell, license or otherwise transfer any of the license or
other rights granted to USSC under this Agreement.

relief may be granted in any action, suit or proceeding which may be brought by

notify USSC in writing of the proposed project and proposed expenditures in
reasonable detail and USSC shall have a period of ten business days within which

shall be reasonably detailed. Misonix shall maintain books and records
concerning Development Funding during the term of this Agreement and for five
(5) years thereafter. USSC and its representatives shall have the right to

                                   WITNESSETH


     WHEREAS, pursuant to the Original Warrant Agreement, the Underwriter was
issued warrants (the "Underwriter's Warrants") entitling it to purchase from the
Company (A) at $10.725 per share, up to an aggregate of 160,000 shares of Common
Stock, $.01 par value of the Company (the "Underwriting Shares"), and (B)
160,000 redeemable warrants at a price of $.165 per redeemable warrant (the

Company's Common Stock (the "Shares") at an exercise price of $12.87 per Share
until 5:30 pm, New York Time on January 23, 1997 (the "Warrant Expiration
Date"); and

     WHEREAS, the Underwriter has not exercised the Underwriter's Warrants but

the signature page (the "Holder(s)"),

     WHEREAS, the Underwriter, the Holders and the Company have certain
differences of opinion as to the rights of the Underwriter and the Holder(s)

                distributed to the public on January 23, 1992."

     This Warrant Certificate certifies that _________, or registered assigns,

"Exercise Price"), of $6.00 per share of Common Stock upon surrender of this
Warrant Certificate and payment of the Exercise Price at an office or agency of
the Company, but subject to the conditions set forth herein and in the warrant
agreement dated as of January 23, 1992 between the Company and Josephthal Lyon &

<PAGE>


     No Warrant may be exercised after 5:30 p.m., New York time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter be void.


     The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference herein and made a part of
this instrument and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
Company and the holders (the words "holders" or "holder" meaning the registered
holders or registered holder) of the Warrants.

     The Warrant Agreement provides that upon the ocurrence of certain events,
the Exercise Price and the type and/or number of the Company's securities
issuable thereupon may, subject to certain conditions, be adjusted. In such
event, the Company will, at the request of the holder, issue a new Warrant
Certificate evidencing the adjustment in the Exercise Price and the number
and/or type of securities issuable upon the exercise of the Warrants; provided,
however, that the failure of the Company to issue such new Warrant Certificates
shall not in any way change, alter, or otherwise impair, the rights of the
holder as set forth in the Warrant Agreement.

     Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided herein and in the Warrant
Agreement, without any charge except for any tax or other governmental charge
imposed in connection with such transfer.

     Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

     The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof; and of any distribution to the holder(s) hereof; and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

                                  MISONIX, INC.
                  1996 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN


                                   1. GENERAL

1.1      Purpose Of The Plan

         The purpose of the MISONIX, INC. 1996 Non-Employee Director Stock
         Option Plan (the "Plan") is to enable MISONIX, INC. (the "Company") to
         attract and retain persons of exceptional ability to serve as directors
         of the Company and to align the interests of directors and shareholders
         in enhancing the value of the Company's common stock, par value $.01
         per share (the "Common Stock").

1.2      Administration Of The Plan

         The Plan shall be administered by the Board of Directors (the "Board")
         which shall have full and final authority in its discretion to
         interpret, administer and amend the provisions of the Plan; to adopt
         rules and regulations for carrying out the Plan; to decide all
         questions of fact arising in the application of the Plan; and to make
         all other determinations necessary or advisable for the administration
         of the Plan.

1.3      Eligible Participants

         Commencing March 27, 1996 each member of the Board who is not an
         employee of the Company or any of its subsidiaries shall be a
         participant (a "Participant") in the Plan.

1.4      Grants Under The Plan

         Grants under the Plan shall be in the form of stock options as
         described in Section II (an "Option" or "Options").

1.5      Shares

         The aggregate number of shares of Common Stock, including shares
         reserved for issuance pursuant to the exercise of Options, which may be
         issued under the terms of the Plan may not exceed 750,000 shares and
         hereby are reserved for such purpose. Whenever any outstanding grant or
         portion thereof expires, is canceled or forfeited or is otherwise
         terminated for any reason without having been exercised, the Common
         Stock allocable to the expired, canceled, forfeited or otherwise
         terminated portion of the grant may again be the subject of further
         grants hereunder.

         Notwithstanding the foregoing, the number of shares of Common Stock
         available for grants at any time under the Plan shall be reduced to

         such lesser amount as may be required pursuant to the methods of
         calculation necessary so that the exemptions provided pursuant to Rule
         16b-3 under the Securities Exchange Act of 1934, as amended (the

                                       B-1


<PAGE>


         "Exchange Act") will continue to be available for transactions
         involving all current and future grants. In addition, during the period
         that any grants remain outstanding under the Plan, the Committee may
         make good faith adjustments with respect to the number of shares of
         Common Stock attributable to such grants for purposes of calculating
         the maximum number of shares of Common Stock available for the granting
         of future grants under the Plan, provided that following such
         adjustments the exemptions provided pursuant to Rule 16b-3 under the
         Exchange Act will continue to be available for transactions involving
         all current and future grants.

1.6 Definitions

         The following definitions shall apply to the Plan:

         (a)      "Disability" shall have the meaning Provided in the Company's
                  applicable disability plan or, in the absence of such a
                  definition, when a Participant becomes totally disabled (as
                  determined by a physician mutually acceptable to the
                  Participant and the Company) before termination of his or her
                  service on the Board if such total disability continues for
                  more than three (3) months.

         (b)      "Fair Market Value" of the Common Stock on any day shall be 
                  (a) if the principal market for the Common Stock is a
                  national securities exchange, the average between the high
                  and low sales prices of the Common Stock on such day as
                  reported by such exchange or on a consolidated tape
                  reflecting transactions on such exchange, (b) if the
                  principal market for the Common Stock is not a national
                  securities exchange and the Common Stock is quoted on the
                  National Association of Securities Dealers Automated
                  Quotations System ("NASDAQ"), and (i) if actual sales price
                  information is available with respect to the Common Stock,
                  the average between the high and low sales prices of the
                  Common Stock on such day on NASDAQ, or (ii) if such
                  information is not available, the average between the
                  highest bid and the lowest asked prices for the Common Stock
                  on such day on NASDAQ, or (c) if the principal market for
                  the Common Stock is not a national securities exchange and
                  the Common Stock is not quoted on NASDAQ, the average
                  between the highest bid and lowest asked prices for the
                  Common Stock on such day as reported on the NASDAQ OTC
                  Bulletin Board Service or by National Quotation Bureau,

                  Incorporated or a comparable service; provided that if
                  clauses (a), (b) and (c) of this Paragraph are all
                  inapplicable, or if no trades have been made or no quotes
                  are available for such day, the fair market value of the
                  Common Stock shall be determined by the Board by any method
                  consistent with applicable regulations adopted by the
                  Treasury Department relating to stock options. The
                  determination of the Board shall be conclusive in
                  determining the fair market value of the Common Stock.

                                   2. OPTIONS

2.1      Terms And Conditions Of Options

         Each Participant shall be granted such number of Options as determined
         from time to time during the term of the Plan by the Board.

2.2      Nonqualified Stock Options

         The terms of the Options shall, at the time of grant, provide that the
         Options will not be treated as incentive stock options within the
         meaning of Section 422 of the Internal Revenue Code of 1986, as amended
         (the "Code").

2 3      Option Price

         The Option price per Share shall be determined by the Board of
         Directors but shall not be less than the Fair Market Value of the
         Common Stock on the date the Option is granted.

2.4      Term And Exercise Of Options

         (a) The term of an Option shall not exceed ten (10) years from the date
         of grant. Except as provided in this Section 2.4, after a Participant
         ceases to serve as a director of the Company for any reason, including,
         without limitation, retirement, or any other voluntary or involuntary
         termination of a Participant's service as a director (a "Termination"),
         the unexercisable portion of an Option shall immediately terminate and
         be null and void, and the unexercised portion of any outstanding
         Options held by such Participant shall terminate and be null and void
         for all purposes after three (3) months have elapsed from the date of
         the Termination unless extended by the Board, in its sole discretion,
         within thirty (30) days from the date of the Termination. Upon a
         Termination as a result of death or Disability, any outstanding Options
         may be exercised by the Participant or the Participant's legal
         representative within twelve (12) months after such death or
         Disability; provided, however, that in no event shall the period extend

         beyond the expiration of the Option term.

         (b) Options shall become exercisable in whole or in part immediately
         from the date of grant. In no event, however, shall an Option be
         exercised after the expiration of ten (10) years from the date of
         grant.

         (c) A Participant, by written notice to the Company, may designate one
         or more persons (and from time to time change such designation)
         including his legal representative, who, by reason of his or her death,
         shall acquire the right to exercise all or a portion of the Option. If
         no designation is made before the death of the Participant, the
         Participant's Option may be exercised by the personal representative of
         the Participant's estate or by a person who acquired the right to
         exercise such option by will or the laws of descent and distribution.
         If the person with exercise rights desires to

                                       B-3


<PAGE>


          exercise any portion of the Option, such person must do so in
          accordance with the terms and conditions of this Plan.

2.5       Notice Of Exercise

          When exercisable pursuant to the terms of the Plan and the governing
          stock option agreement, an Option shall be exercised by the
          Participant as to all or part of the shares subject to the Option by
          delivering written notice of exercise to the Company at its principal
          business office or such other office as the Company may from time to
          time direct, (a) specifying the number of shares to be purchased, (b)
          accompanied by cash or a certified check payable to the Company in an
          amount equal to the full exercise price of the number of shares being
          exercised or with previously acquired shares of Common Stock having an
          aggregate Fair Market Value, on the date of exercise, equal to the
          aggregate exercise price of all Options being exercised (provided that
          such shares were not acquired less than six (6) months prior to such
          exercise date) or with any combination of cash, certified check or
          shares of Common Stock, and (c) containing such further provisions
          consistent with the provisions of the Plan as the Company may from
          time to time prescribe. No Option may be exercised after the
          expiration of the term specified in Section 2.4 hereof.

2.6       Limitation Of Exercise Periods

          The Board may limit the time periods within which an Option may be
          exercised if a limitation on exercise is deemed necessary in order to
          effect compliance with applicable law.

                              3. GENERAL PROVISIONS


3.1       General Restrictions

          Each grant under the Plan shall be subject to the requirement that if
          the Board shall determine, at any time, that (a) the listing,
          registration or qualification of the shares of Common Stock subject or
          related thereto upon any securities exchange or under any state or
          federal law, or (b) the consent or approval of any government
          regulatory body, or (c) an agreement by the Participant with respect
          to the disposition of shares of Common Stock, is necessary or
          desirable as a condition of, or in connection with, the granting or
          the issuance or purchase of shares of Common Stock thereunder, such
          grant may not be consummated in whole or in part unless such listing,
          registration, qualification, consent, approval or agreement shall have
          been effected or obtained free of any conditions not acceptable to the
          Board.

3.2      Adjustments For Changes In Capitalization

         Notwithstanding any other provisions of the Plan, in the event of any
         change in the outstanding Common Stock by reason of a stock dividend,
         recapitalization, merger or consolidation in which the Company is the
         surviving corporation, split-up, combination or exchange of shares or
         the like, the aggregate number and kind of shares subject to the

                                       B-4


<PAGE>


          Plan, the aggregate number and kind of shares subject to each
          outstanding option and the exercise price thereof shall be
          appropriately adjusted by the Board, whose determination shall be
          conclusive.

          In the event of (a) the liquidation or dissolution of the Company, (b)
          a merger or consolidation in which the Company is not the surviving
          corporation, or (c) any other capital reorganization in which more
          than 50% of the shares of Common Stock of the Company entitled to vote
          are exchanged, any outstanding options shall then remain exercisable
          within the period of thirty (30) days commencing upon the date of the
          action of the shareholders (or the Board of Directors if shareholders'
          action is not required) is taken to approve the transaction and upon
          the expiration of that period all options and all rights thereto shall
          automatically terminate, unless other provision is made therefor in
          the transaction.

3.3       Amendments

          Without further approval of the shareholders, the Board may
          discontinue the Plan at any time and may amend it from time to time in
          such respect as the Board may deem advisable, unless shareholder or
          regulatory approval is required by law or regulation, and subject to
          any conditions established by the terms of such amendment; provided,

          however, that the Plan may not be amended more than once every six (6)
          months other than to comport with changes in the Code, the Employee
          Retirement Income Security Act or the rules thereunder.

3.4       Modification, Substitution Or Cancellation Of Grants

          No rights or obligations under any outstanding Option may be altered
          or impaired without the Participant's consent. Any grant under the
          Plan may be canceled at any time with the consent of the Participant,
          and a new grant may be provided to such Participant in lieu thereof.

3.5       Shares Subject To The Plan

          Shares distributed pursuant to the Plan shall be made available from
          authorized but unissued shares or from shares purchased or otherwise
          acquired by the Company for use in the Plan, as shall be determined
          from time to time by the Board.

3.6       Rights Of A Shareholder

          Participants under the Plan, unless otherwise provided by the Plan,
          shall have no rights as shareholders by reason thereof unless and
          until certificates for shares of Common Stock are issued to them;
          provided, however, that until such stock certificate is issued, any
          Option holder using previously acquired shares of Common Stock in
          payment of an Option exercise price shall continue to have the rights
          of a shareholder with respect to such previously acquired shares.

                                       B-5



<PAGE>

3.7       Withholding

          If a Participant is to experience a taxable event in connection with
          the receipt of shares of Common Stock pursuant to an Option exercise,
          the Participant shall pay the amount equal to the federal, state and
          local income taxes and other amounts as may be required by law to be
          withheld to the Company prior to the issuance of such shares of Common
          Stock.

3.8       Non-assignability

          Except as expressly provided in the Plan, no grant shall be
          transferable except by will, the laws of descent and distribution or a
          qualified domestic relations order ("QDRO") as defined by the Code or
          Title I of the Employee Retirement Income Security Act of 1974, as
          amended, or the rules thereunder. During the lifetime of the
          Participant, except as expressly provided in the Plan, grants under
          the Plan shall be exercisable only by such Participant or by the
          guardian or legal representative of such Participant or pursuant to a
          QDRO.


3.9       Nonuniform Determinations

          Determinations by the Board under the Plan (including, without
          limitation, determinations of the persons to receive grants, the form,
          amount and timing of such grants, and the terms and provisions of such
          grants and the agreements evidencing the same) need not be uniform and
          may be made by it selectively among persons who receive, or are
          eligible to receive, awards under the Plan, whether or not such
          persons are similarly situated.

3.10      Effective Date; Duration

          The Plan shall be subject to approval by the holders of a majority of
          the Company's stock outstanding and entitled to vote thereon at the
          next meeting of its shareholders. No Options granted hereunder may be
          exercised prior to such approval, provided that the date of grant of
          any Options granted hereunder shall be determined as if the Plan had
          not been subject to such approval. Notwithstanding the foregoing, if
          the Plan is not approved by a vote of the shareholders of the Company
          on or before March 26, 1997, the Plan and any Options granted
          hereunder shall terminate.

3.11      Governing Law

          The Plan and all actions taken thereunder shall be governed by and
          construed in accordance with the laws of the State of New York.

                    1996 EMPLOYEE INCENTIVE STOCK OPTION PLAN

                                       of

                                  MISONIX, INC.


I.   PURPOSES OF THE PLAN.

     This stock option plan (the "Plan") is designed to provide an incentive to
     key employees (including directors and officers who are key employees) of
     MISONIX, INC., a New York corporation (the "Company"), and its present and
     future subsidiary corporations, as defined in Paragraph 19
     ("Subsidiaries"), and to offer an additional inducement in obtaining the
     services of such individuals. The Plan provides for the grant of "incentive
     stock options" ("ISOs") within the meaning of Section 422 of the Internal
     Revenue Code of 1986, as amended (the "Code"), but the Company makes no
     warranty as to the qualification of any option as an "incentive stock
     option" under the Code.

II.  STOCK SUBJECT TO THE PLAN.

     Subject to the provisions of Paragraph 12, the aggregate number of shares
     of Common Stock, $.01 par value per share, of the Company ("Common Stock")
     for which options may be granted under the Plan shall not exceed 300,000.
     Such shares of Common Stock may, in the discretion of the Board of
     Directors of the Company (the "Board of Directors"), consist either in
     whole or in part of authorized but unissued shares of Common Stock or
     shares of Common Stock held in the treasury of the Company. The Company
     shall at all times during the term of the Plan reserve and keep available
     such number of shares of Common Stock as will be sufficient to satisfy the
     requirements of the Plan. Subject to the provisions of Paragraph 13, any
     shares of Common Stock subject to an option which for any reason expires,
     is canceled or is terminated unexercised or which ceases for any reason to
     be exercisable shall again become available for the granting of options
     under the Plan.

III. ADMINISTRATION OF THE PLAN.

     The Plan shall be administered by a committee of the Board of Directors
     (the "Committee") consisting of not less than three Directors, each of whom
     shall be a "Non-Employee Director" within the meaning of Rule 16b-3 (or any
     successor rule or regulation) promulgated under the Securities Exchange Act
     of 1934, as amended (the "Exchange Act"). A majority of the members of the
     Committee shall constitute a quorum, and the acts of a majority of the
     members present at any meeting at which a quorum is present, and any acts
     approved in writing by all members without a meeting, shall be the acts of
     the Committee.


                                     A-1



<PAGE>



     Subject to the express provisions of the Plan, the Committee shall have the
     authority, in its sole discretion, to determine the key employees who shall
     receive options; the times when they shall receive options; the number of
     shares of Common Stock to be subject to each option; the term of each
     option; the date each option shall become exercisable; whether an option
     shall be exercisable in whole, in part or in installments, and, if in
     installments, the number of shares of Common Stock to be subject to each
     installment; whether the installments shall be cumulative; the date each
     installment shall become exercisable and the term of each installment;
     whether to accelerate the date of exercise of any installment; whether
     shares of Common Stock may be issued on exercise of an option as partly
     paid, and, if so, the dates when future installments of the exercise price
     shall become due and the amounts of such installments; the exercise price
     of each option; the form of payment of the exercise price; the amount, if
     any, necessary to satisfy the Company's obligation to withhold taxes;
     whether to restrict the sale or other disposition of the shares of Common
     Stock acquired upon the exercise of an option and to waive any such
     restriction; whether to subject the exercise of all or any portion of an
     option to the fulfillment of contingencies as specified in the contract
     referred to in Paragraph 11 (the "Contract"), including, without
     limitation, contingencies relating to entering into a covenant not to
     compete with the Company and its Parent and Subsidiaries, to financial
     objectives for the Company, a Subsidiary, a division, a product line or
     other category, and/or the period of continued employment of the optionee
     with the Company, its Parent or its Subsidiaries, and to determine whether
     such contingencies have been met; to construe the respective Contracts and
     the Plan; with the consent of the optionee, to cancel or modify an option,
     provided such option as modified would be permitted to be granted on such
     date under the terms of the Plan; to prescribe, amend and rescind rules and
     regulations relating to the Plan; and to make all other determinations
     necessary or advisable for administering the Plan. The determinations of
     the Committee on the matters referred to in this Paragraph 3 shall be
     conclusive.

IV.  ELIGIBILITY.

     The Committee may, consistent with the purposes of the Plan, grant options
     from time to time, to key employees (including directors and officers who
     are key employees) of the Company or any of its Subsidiaries. Options
     granted shall cover such number of shares of Common Stock as the Committee
     may determine; provided, however, that the aggregate market value
     (determined at the time the option is granted) of the shares of Common
     Stock for which any eligible person may be granted ISOs under the Plan or
     any other plan of the Company, or of a Parent or a Subsidiary of the
     Company, which are exercisable for the first time by such optionee during

     any calendar year shall not exceed $100,000. The $100,000 ISO limitation
     shall be applied by taking ISOs into account in the order in which they
     were granted. Any option (or the portion thereof) granted in excess of such
     amount shall be treated as a nonqualified stock option.

V.   EXERCISE PRICE.

     The exercise price of the shares of Common Stock under each option shall be
     determined by the Committee; provided, however, that the exercise price
     shall not be less than 100% of the fair market value of the Common Stock
     subject to such option on the date of


                                       A-2
<PAGE>



     grant; and further provided, that if, at the time an ISO is granted, the
     optionee owns (or is deemed to own under Section 424(d) of the Code) stock
     possessing more than 10% of the total combined voting power of all classes
     of stock of the Company, of any of its Subsidiaries or of a Parent, the
     exercise price of such ISO shall not be less than 110% of the fair market
     value of the Common Stock subject to such ISO on the date of grant.

     The fair market value of the Common Stock on any day shall be (a) if the
     principal market for the Common Stock is a national securities exchange,
     the average between the high and low sales prices of the Common Stock on
     such day as reported by such exchange or on a consolidated tape reflecting
     transactions on such exchange, (b) if the principal market for the Common
     Stock is not a national securities exchange and the Common Stock is quoted
     on the National Association of Securities Dealers Automated Quotations
     System ("NASDAQ"), and (i) if actual sales price information is available
     with respect to the Common Stock, the average between the high and low
     sales prices of the Common Stock on such day on NASDAQ, or (ii) if such
     information is not available, the average between the highest bid and the
     lowest asked prices for the Common Stock on such day on NASDAQ, or (c) if
     the principal market for the Common Stock is not a national securities
     exchange and the Common Stock is not quoted on NASDAQ, the average between
     the highest bid and lowest asked prices for the Common Stock on such day as
     reported on the NASDAQ OTC Bulletin Board Service or by National Quotation
     Bureau, Incorporated or a comparable service; provided that if clauses (a),
     (b) and (c) of this Paragraph are all inapplicable, or if no trades have
     been made or no quotes are available for such day, the fair market value of
     the Common Stock shall be determined by the Committee by any method
     consistent with applicable regulations adopted by the Treasury Department
     relating to stock options. The determination of the Committee shall be
     conclusive in determining the fair market value of the Common Stock.

VI.  TERM.

     The term of each option granted pursuant to the Plan shall be such term as
     is established by the Committee, in its sole discretion, at or before the
     time such option is granted; provided, however, that the term of each

     option granted pursuant to the Plan shall be for a period not exceeding 10
     years from the date of grant thereof, and further, provided, that if, at
     the time an option is granted, the optionee owns (or is deemed to own under
     Section 424(d) of the Code) stock possessing more than 10% of the total
     combined voting power of all classes of stock of the Company, of any of its
     Subsidiaries or of a Parent, the term of the option shall be for a period
     not exceeding five years from the date of grant. Options shall be subject
     to earlier termination as hereinafter provided.

VII. EXERCISE.

     An option (or any part or installment thereof), to the extent then
     exercisable, shall be exercised by giving written notice to the Company at
     its principal office (at present 1938 New Highway, Farmingdale, New York
     11735, Attn: Employee Stock Option Committee), stating which option is
     being exercised, specifying the number of shares of Common Stock as to
     which such option is being exercised and accompanied by payment


                                       A-3
<PAGE>


     in full of the aggregate exercise price therefor (or the amount due on
     exercise if the Contract permits installment payments) (a) in cash or by
     certified check or (b) if the Contract (at the time of grant) so permits,
     with previously acquired shares of Common Stock having an aggregate fair
     market value, on the date of exercise, equal to the aggregate exercise
     price of all options being exercised, or with any combination of cash,
     certified check or shares of Common Stock.

     A person entitled to receive Common Stock upon the exercise of an option
     shall not have the rights of a shareholder with respect to such shares of
     Common Stock until the date of issuance of a stock certificate to him for
     such shares; provided, however, that until such stock certificate is
     issued, any option holder using previously acquired shares of Common Stock
     in payment of an option exercise price shall continue to have the rights of
     a shareholder with respect to such previously acquired shares.

     In no case may a fraction of a share of Common Stock be purchased or issued
     under the Plan.

VIII. TERMINATION OF EMPLOYMENT.

     Any holder of an option whose employment with the Company (and its Parent
     and Subsidiaries) has terminated for any reason other than his death or
     Disability (as defined in Paragraph 19) may exercise such option, to the
     extent exercisable on the date of such termination, at any time within 90
     days after the date of termination, but not thereafter and in no event
     after the date the option would otherwise have expired; provided, however,
     that if his employment shall be terminated either (a) for cause, or (b)
     without the consent of the Company, said option shall terminate
     immediately. Options granted under the Plan shall not be affected by any
     change in the status of the holder so long as he continues to be a

     full-time employee of the Company, its Parent or any of its Subsidiaries
     (regardless of having been transferred from one corporation to another).

     For the purposes of the Plan, an employment relationship shall be deemed to
     exist between an individual and a corporation if, at the time of the
     determination, the individual was an employee of such corporation for
     purposes of Section 422(a) of the Code. As a result, an individual on
     military, sick leave or other bona fide leave of absence shall continue to
     be considered an employee for purposes of the Plan during such leave if the
     period of the leave does not exceed 90 days, or, if longer, so long as the
     individual's right to reemployment with the Company (or a related
     corporation) is guaranteed either by statute or by contract. If the period
     of leave exceeds 90 days and the individual's right to reemployment is not
     guaranteed by statute or by contract, the employment relationship shall be
     deemed to have terminated on the 91st day of such leave.

     Nothing in the Plan or in any option granted under the Plan shall confer on
     any individual any right to continue in the employ of the Company, its
     Parent or any of its Subsidiaries, or interfere in any way with the right
     of the Company, its Parent or any of its Subsidiaries to terminate the
     employee's employment at any time for any reason whatsoever without
     liability to the Company, its Parent or any of its Subsidiaries.

IX.  DEATH OR DISABILITY OF AN OPTIONEE.

     If an optionee dies (a) while he is employed by the Company, its Parent or
     any of its Subsidiaries, (b) within 90 days after the termination of his
     employment (unless such termination was for cause or without the consent of
     the Company) or (c) within one year following the termination of his
     employment by reason of Disability, the option may be exercised, to the
     extent exercisable on the date of his death, by his executor, administrator
     or other person at the time entitled by law to his rights under such
     option, at any time within one year after death, but not thereafter and in
     no event after the date the option would otherwise have expired.

     Any optionee whose employment has terminated by reason of Disability may
     exercise his option, to the extent exercisable upon the effective date of
     such termination, at any time within one year after such date, but not
     thereafter and in no event after the date the option would otherwise have
     expired.

X.   COMPLIANCE WITH SECURITIES LAWS.

     The Committee may require, in its discretion, as a condition to the
     exercise of any option that either (a) a Registration Statement under the
     Securities Act of 1933, as amended (the "Securities Act"), with respect to
     the shares of Common Stock to be issued upon such exercise shall be

     effective and current at the time of exercise, or (b) there is an exemption
     from registration under the Securities Act for the issuance of shares of
     Common Stock upon such exercise. Nothing herein shall be construed as
     requiring the Company to register shares subject to any option under the
     Securities Act.

     The Committee may require the optionee to execute and deliver to the
     Company his representation and warranty, in form and substance satisfactory
     to the Committee, that the shares of Common Stock to be issued upon the
     exercise of the option are being acquired by the optionee for his own
     account, for investment only and not with a view to the resale or
     distribution thereof. In addition, the Committee may require the optionee
     to represent and warrant in writing that any subsequent resale or
     distribution of shares of Common Stock by such optionee will be made only
     pursuant to (i) a Registration Statement under the Securities Act which is
     effective and current with respect to the shares of Common Stock being
     sold, or (ii) a specific exemption from the registration requirements of
     the Securities Act, but in claiming such exemption, the optionee shall
     prior to any offer of sale or sale of such shares of Common Stock provide
     the Company with a favorable written opinion of counsel, in form and
     substance satisfactory to the Company, as to the applicability of such
     exemption to the proposed sale or distribution.

     In addition, if at any time the Committee shall determine in its discretion
     that the listing or qualification of the shares of Common Stock subject to
     such option on any securities exchange or under any applicable law, or the
     consent or approval of any governmental regulatory body, is necessary or
     desirable as a condition to, or in connection with, the granting of an
     option or the issue of shares of Common Stock thereunder, such option may
     not be exercised in whole or in part unless such listing, qualification,
     consent or


                                       A-5
<PAGE>



     approval shall have been effected or obtained free of any conditions not
     acceptable to the Committee.

XI.  STOCK OPTION CONTRACTS.

     Each option shall be evidenced by an appropriate Contract which shall be
     duly executed by the Company and the optionee, and shall contain such terms
     and conditions not inconsistent herewith as may be determined by the
     Committee.

XII. ADJUSTMENTS UPON CHANGES IN COMMON STOCK.

     Notwithstanding any other provisions of the Plan, in the event of any
     change in the outstanding Common Stock by reason of a stock dividend,
     recapitalization, merger or consolidation in which the Company is the
     surviving corporation, split-up, combination or exchange of shares or the

     like, the aggregate number and kind of shares subject to the Plan, the
     aggregate number and kind of shares subject to each outstanding option and
     the exercise price thereof shall be appropriately adjusted by the Board of
     Directors, whose determination shall be conclusive.

     In the event of (a) the liquidation or dissolution of the Company, (b) a
     merger or consolidation in which the Company is not the surviving
     corporation, or (c) any other capital reorganization in which more than 50%
     of the shares of Common Stock of the Company entitled to vote are
     exchanged, any outstanding options shall vest in their entirety and become
     exercisable within the period of thirty (30) days commencing upon the date
     of the action of the shareholders (or the Board of Directors if
     shareholders' action is not required) is taken to approve the transaction
     and upon the expiration of that period all options and all rights thereto
     shall automatically terminate, unless other provision is made therefor in
     the transaction.

XIII. AMENDMENTS AND TERMINATION OF THE PLAN.

     The Plan was adopted by the Board of Directors on March 27, 1996. No option
     may be granted under the Plan after March 26, 2006. The Board of Directors,
     without further approval of the Company's shareholders, may at any time
     suspend or terminate the Plan, in whole or in part, or amend it from time
     to time in such respects as it may deem advisable, including, without
     limitation, in order that options granted hereunder meet the requirements
     for "incentive stock options" under the Code, to comply with applicable
     requirements of the Securities Act and the Exchange Act, and to conform to
     any change in applicable law or to regulations or rulings of administrative
     agencies; provided, however, that no amendment shall be effective without
     the requisite prior or subsequent shareholder approval which would (a)
     except as contemplated in Paragraph 12, increase the maximum number of
     shares of Common Stock for which options may be granted under the Plan, (b)
     materially increase the benefits to participants under the Plan or (c)
     change the eligibility requirements for individuals entitled to receive
     options hereunder. No termination, suspension or amendment of the Plan
     shall, without the consent of the holder of an existing option affected
     thereby, adversely affect his rights under such option. The power of the
     Committee to construe and administer any options granted

                                       A-6
<PAGE>


     under the Plan prior to the termination or suspension of the Plan
     nevertheless shall continue after such termination or during such
     suspension.

XIV. NON-TRANSFERABILITY OF OPTIONS.

     No option granted under the Plan shall be transferable otherwise than by
     will or the laws of descent and distribution or a qualified domestic
     relations order ("QDRO") as defined by the Code or Title I of the Employee
     Retirement Income Security Act of 1974, as amended, or the rules
     thereunder, and options may be exercised, during the lifetime of the holder

     thereof, only by him or his legal representatives or pursuant to a QDRO.
     Except to the extent provided above, options may not be assigned,
     transferred, pledged, hypothecated or disposed of in any way (whether by
     operation of law or otherwise) and shall not be subject to execution,
     attachment or similar process.

XV.  WITHHOLDING TAXES.

     The Company may withhold cash and/or shares of Common Stock to be issued
     with respect thereto having an aggregate fair market value equal to the
     amount which it determines is necessary to satisfy its obligation to
     withhold Federal, state and local income taxes or other taxes incurred by
     reason of the grant or exercise of an option, its disposition, or the
     disposition of the underlying shares of Common Stock. Alternatively, the
     Company may require the holder to pay to the Company such amount, in cash,
     promptly upon demand. The Company shall not be required to issue any shares
     of Common Stock pursuant to any such option until all required payments
     have been made. Fair market value of the shares of Common Stock shall be
     determined in accordance with Paragraph 5.

XVI. LEGENDS; PAYMENT OF EXPENSES.

     The Company may endorse such legend or legends upon the certificates for
     shares of Common Stock issued upon exercise of an option under the Plan and
     may issue such "stop transfer" instructions to its transfer agent in
     respect of such shares as it determines, in its discretion, to be necessary
     or appropriate to (a) prevent a violation of, or to perfect an exemption
     from, the registration requirements of the Securities Act, (b) implement
     the provisions of the Plan or any agreement between the Company and the
     optionee with respect to such shares of Common Stock, or (c) permit the
     Company to determine the occurrence of a "disqualifying disposition," as
     described in Section 421(b) of the Code, of the shares of Common Stock
     transferred upon the exercise of an option granted under the Plan.

     The Company shall pay all issuance taxes with respect to the issuance of
     shares of Common Stock upon the exercise of an option granted under the
     Plan, as well as all fees and expenses incurred by the Company in
     connection with such issuance.


                                       A-7
<PAGE>

XVII. USE OF PROCEEDS.

     The cash proceeds from the sale of shares of Common Stock pursuant to the
     exercise of options under the Plan shall be added to the general funds of
     the Company and used for such corporate purposes as the Board of Directors
     may determine.

XVIII.  SUBSTITUTIONS   AND  ASSUMPTIONS  OF  OPTIONS  OF  CERTAIN   CONSTITUENT
        CORPORATIONS.

     Anything in this Plan to the contrary notwithstanding, the Board of

     Directors may, without further approval by the shareholders, substitute new
     options for prior options of a Constituent Corporation (as defined in
     Paragraph 19) or assume the prior options of such Constituent Corporation.

XIX. DEFINITIONS.

     a.   Subsidiary.  The term  "Subsidiary"  shall have the same definition as
          "subsidiary corporation" in Section 424(f) of the Code.

     b.   Parent. The term "Parent" shall have the same definition as "parent
          corporation" in Section 424(e) of the Code.

     c.   Constituent Corporation. The term "Constituent Corporation" shall mean
          any corporation which engages with the Company, its Parent or any
          Subsidiary in a transaction to which Section 424(a) of the Code
          applies (or would apply if the option assumed or substituted were an
          ISO), or any Parent or any Subsidiary of such corporation.

     d.   Disability. The term "Disability" shall mean a permanent and total
          disability within the meaning of Section 22(e)(3) of the Code.

XX.  GOVERNING LAW.

     The Plan, such options as may be granted hereunder and all related matters
     shall be governed by, and construed in accordance with, the laws of the
     State of New York.

XXI. PARTIAL INVALIDITY.

     The invalidity or illegality of any provision herein shall not affect the
     validity of any other provision.

XXII. SHAREHOLDER APPROVAL.

     The Plan shall be subject to approval by the holders of a majority of the
     Company's stock outstanding and entitled to vote thereon at the next
     meeting of its shareholders. No options granted hereunder may be exercised
     prior to such approval, provided that the

                                       A-8
<PAGE>


     date of grant of any options granted hereunder shall be determined as if
     the Plan had not been subject to such approval. Notwithstanding the
     foregoing, if the Plan is not approved by a vote of the shareholders of the
     Company on or before March 26, 1997, the Plan and any options granted
     hereunder shall terminate.

                    Second Amendment to Employment Agreement

     Second Amendment ("Second Amendment") entered into on the 5 day of August,
1997 to a certain Employment Agreement dated as of September 1, 1995, as
modified by an Amendment dated July, 1996 (which agreements are collectively
called the "Existing Employment Agreement") between MISONIX, INC., a New York
corporation (hereinafter called the "Company") with offices at 1938 New Highway,
Farmingdale, New York 11735 and JOSEPH LIBRIZZI, residing at 10 Indian Trace,
Kings Park, New York 11754 (hereinafter called the "Employee").

                              W I T N E S S E T H:

     WHEREAS, the Company and the Employee desire to continue the services of
Employee upon the terms and conditions contained in the Existing Employment
Agreement, as hereby amended.

     NOW, THEREFORE, in consideration of the mutual covenants, conditions and
promises contained herein, the parties hereby agree as follows:

1.   Terms and References

     Unless otherwise expressly provided in this Amendment, all terms,
definitions and references in the Existing Employment Agreement shall have the
same meanings when used herein.

2.   Term of Employment

     The term of employment provided in this Second Amendment shall be for the
13 months commencing September 1, 1997 and ending September 30, 1998.
Accordingly, the reference in paragraph 1 of the Existing Employment Agreement
in the third line thereof shall be to the 13 month period ending September 30,
1998; the balance of paragraph 1 of the Existing Employment Agreement shall
remain in effect and any future renewal periods shall be for the twelve month
period commencing October 1st.



3.   Paragraph 4 of the Existing Employment Agreement, dealing with
     Compensation, is hereby amended as follows:


<PAGE>



a)   The base salary provided in paragraph 4(a) shall be $200,000 per annum
     (with an additional monthly payment of $16,666.67 to be made for the
     thirteenth month of the initial term hereof, i.e., September, 1998);



b)   The incentive compensation provided in paragraph 4(b) of the Employment
     Agreement shall be modified to read as follows for all years after Fiscal
     1997:

     "(b) Not later than one hundred twenty (120) days after the end of the
     fiscal year of the Company ending on the 30th day of June immediately prior
     to the expiration date of that year for employment (so that, for example,
     the results of the Company's fiscal year ending June 30, 1998 shall be
     applicable to the initial 13 months of employment under this Second
     Amendment), the Company shall pay to Employee, as incentive compensation:

     If Pretax Operating Earnings for fiscal year are:

                                         Incentive Compensation Payment

     less than $4,000,000      - None
     $4,000,000 to $5,500,000  - 5% of pretax operating earnings in this range
     $5,500,001 to $7,000,000  - 7.5% of pretax operating earnings in this
                                 range
     $7,000,001 to $9,625,000  - 10% of pretax operating earnings in this range

     In no event shall the Employee be entitled to more than $450,000 in
incentive compensation either for the initial 13 month term of this Second
Amendment or for any renewal term thereafter.

     For purposes hereof, "pretax operating earnings" of the Company shall mean,
with respect to any fiscal year, the operating income (including royalties and
license fees) if any, but excluding, without limitation, interest income, for
such fiscal year as set forth in the audited, financial statements of the
Company included in its Annual Report to Stockholders for such fiscal year,
before deduction of (i) taxes based on income, or (ii) of the incentive
compensation to be paid to Employee for such fiscal year.

     For each Renewal Period hereunder, the calculation of incentive
compensation shall be made upon the results of the Company's fiscal year
expiring on the 30th day of June during such Renewal Period. In the event of a
change of the Company's fiscal year, the calculation period for the incentive
compensation shall be equitably adjusted."

     Subparagraphs (c) and (d) of paragraph 4 shall remain as presently stated
in the Existing Employment Agreement.

4.   In the event of the death or disability of Employee or other severance of
     employment of Employee during the pendancy of the initial term or a renewal
     term for any reason (except (a) by virtue of non-renewal, or (b)
     termination by the Company for cause pursuant to


<PAGE>


     paragraph 10 of the existing Employment Agreement), Employee shall be
     entitled to the incentive compensation calculated up to the date of death,
     disability or other date of such severance, as the case may be; Employee's

     entitlement shall be calculated by multiplying the dollar amount of
     incentive compensation he would be entitled to for the entire initial term
     or renewal term in which such death, disability or other such severance
     occurs, by a fraction whose numerator is the number of months in such term
     prior to death, disability or such other severance (not to exceed 12) and
     whose denominator is the number "12".

5.   Employee shall be furnished with an executive style automobile for use in
     the Company's business at the Company's expense, with all reasonable
     expenses, directly relating thereto, to be paid or reimbursed by the
     Company.

6.   All notices to be given hereunder may also be transmitted by hand or by
     receipted overnight courier (such as UPS or Federal Express).

7.   Except as expressly modified by this Second Amendment, the terms and
     conditions of the Existing Employment Agreement shall remain in full force
     and effect. In the event of any conflict or inconsistency between the
     Existing Employment Agreement and this Second Amendment, the terms of this
     Second Amendment shall prevail.

     IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Second Amendment on the day and year first above written.
