ITEM 4. Description of Securities.

Not Applicable.

Item 5. Interest of Named Experts and Counsel.

Not Applicable.

Item 6. Indemnification of Directors and Officers

Section 722 of the New York Business Corporation Law ("NYBCL") permits, in general, a New York corporation to indemnify any person made, or threatened to be made, a party to an action or proceeding by reason of the fact that he or

2

she was a director or officer of the corporation, or served another entity in any capacity at the request of the corporation, against any judgment, fines, amounts paid in settlement and reasonable expenses, including attorney's fees actually and necessarily incurred as a result of such action or proceeding, or any appeal therein, if such person acted in good faith, for a purpose he or she reasonably believed to be in, or, in the case of service for another entity, not opposed to, the best interests of the corporation and, in criminal actions or proceedings, in addition had no reasonable cause to believe that his or her conduct was unlawful. Section 723 of the NYBCL permits the corporation to pay in advance of a final disposition of such action or proceeding the expenses incurred in defending such action or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount as, and to the extent, required by statute. Section 721 of the NYBCL provides that indemnification and advancement of expense provisions contained in the NYBCL shall not be deemed exclusive of any rights to which a director or officer seeking indemnification or advancement of expenses may be entitled, provided no indemnification may be made on behalf of any director or officer if a judgment or other final adjudication adverse to the director or officer establishes that his or her acts were committed in bad faith or were the result of active or deliberate dishonesty and were material to the cause of action so adjudicated, or that he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled.

Article Seventh of the Registrant's Certificate of Incorporation provides, in general, that the Registrant may indemnify, to the fullest extent permitted by applicable law, every person threatened to be made a party to any action, suit or proceeding by reason of the fact that such person is or was an officer or director or was serving at the request of the Registrant as a director, officer, employee, agent or trustee of another corporation, business, partnership, joint venture, trust, employee benefit plan, or other enterprise, against expenses, judgments, fines and amounts paid in settlement in connection with such suit or proceeding. Article Seventh of the Certificate of Incorporation also provides that the Registrant may indemnify and advance expenses to those persons as authorized by resolutions of a majority of the Board of Directors or shareholders, agreement, directors' or officers' liability insurance policies, or any other form of indemnification agreement.

In accordance with that provision of the Certificate of Incorporation, the Registrant shall indemnify any officer or director (including officers and directors serving another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise in any capacity at the Registrant's request) made, or threatened to be made, a party to an action or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that he or she was serving in any of those capacities against judgments, fines, amounts paid in settlement and reasonable expenses (including attorney's fees) incurred as a result of such action or proceeding. Indemnification would not be available under Article Seventh of the Certificate of Incorporation if a judgment or other final adjudication adverse to such director or officer establishes that (i) his or her acts were committed in bad faith or were the result of active and deliberate dishonesty and, in either case, were material to the cause of action so adjudicated, or (ii) he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled. Article Seventh of the Certificate of Incorporation further stipulates that the rights granted therein are contractual in nature.

At present, there is no pending litigation or other proceeding involving a director or officer of the Registrant as to which indemnification is being sought, nor is the Registrant aware of any threatened litigation that may result in claims for indemnification by any officer or director.

Item 7. Exemption From Registration Claimed.

Item 9. Undertakings

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such

4

director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

EXHIBIT 4

2001 EMPLOYEE STOCK OPTION PLAN

OF

MISONIX, INC.

1. 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 (i) "incentive stock options" ("ISOs") within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") and (ii) non-qualified stock options.

2. 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 1,000,000. 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.

3. 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.

8

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; whether options shall be ISOs or non-qualified 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 option; 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.

4. 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 fair 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 non-qualified stock option.

9

5. 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 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.

6. 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 ISO is granted, the optionee owns (or is deemed to own under Section 424(d) of the Code)

10

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.

7. 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 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, (b) with 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 (c) by reducing the number of shares of Common Stock otherwise deliverable to the holder of an option upon exercise of the option, or with any combination of cash, certified check, shares of Common Stock or reduction as aforesaid.

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.

8. TERMINATION OF EMPLOYMENT.

Any holder of an option whose employment with the Company (and its Parent and Subsidiaries) is 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).

11

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.

9. 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.

10. 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

12

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

11. 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.

12. 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,

13

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.

13. AMENDMENTS AND TERMINATION OF THE PLAN.

The Plan was adopted by the Board of Directors on October 30, 2000. No option may be granted under the Plan after October 29, 2010. 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 "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 under the Plan prior to the termination or suspension of the Plan nevertheless shall continue after such termination or during such suspension.

14. NON-TRANSFERABILITY OF OPTIONS.

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.

Re: 2001 Employee Stock Option Plan

Dear Sirs:

We are acting as counsel to MISONIX, INC., a New York corporation (the "Company"), in connection with the preparation and filing with the Securities and Exchange Commission (the "Commission") of a Registration Statement on Form S-8 (the "Registration Statement") under the Securities Act of 1933, as amended (the "Act"). The Registration Statement relates to 1,000,000 shares of the Company's common stock, $0.01 par value per share ("Common Stock"), which are to be issued pursuant to the Company's 2001 Employee Stock Option Plan (the "Employee Plan"). The shares of Common Stock which are to be issued pursuant to the Employee Plan are hereinafter referred to as the "Shares".

In connection with this opinion, we have examined and relied upon copies certified or otherwise identified to our satisfaction of: (i) the Employee Plan; (ii) the Company's Certificate of Incorporation, as amended and By-laws, as amended; (iii) the minute books and other records of corporate proceedings of the Company, as made available to us by officers of the Company; and have reviewed such matters of law as we have deemed necessary or appropriate for the purpose of rendering this opinion.

For purposes of this opinion we have assumed the authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as certified or photostatic copies, and the authenticity of the originals of all documents submitted to us as copies. We have also assumed the legal capacity of all natural persons, the genuineness of all signatures on all documents examined by us, the authority of such persons signing on behalf of the parties thereto other than the Company and the due authorization, execution and delivery of all documents by the parties thereto other than the Company. As to certain factual matters material to the opinion expressed herein, we have relied to the extent we deemed proper upon representations, warranties

18

and statements as to factual matters of officers and other representatives of the Company. Our opinion expressed below is subject to the qualification that we express no opinion as to any law other than the laws of the State of New York and the federal laws of the United States of America. Without limiting the foregoing, we express no opinion with respect to the applicability thereto or effect of municipal laws or the rules, regulations or orders of any municipal agencies within any such state.

Based upon and subject to the foregoing qualifications, assumptions and limitations and the further limitations set forth below, it is our opinion that the Shares to be issued by the Company pursuant to the Employee Plan have been duly authorized and reserved for issuance and, when certificates for the Shares have been duly executed by the Company, countersigned by a transfer agent, duly registered by a registrar for the Shares and issued and paid for in accordance with the terms of the Employee Plan, the Shares will be validly issued, fully paid and non-assessable.

This opinion is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein. We assume no obligation to revise or supplement this opinion should the present laws of the State of New York or the federal laws of the United States of America be changed by legislative action, judicial decision or otherwise.

We hereby consent to the filing of this letter as an exhibit to the Registration Statement. In giving such consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission promulgated thereunder.

This opinion is furnished to you in connection with the filing of the Registration Statement and is not to be used, circulated, quoted or otherwise relied upon for any other purpose.

Very truly yours,
