INDUCEMENT RESTRICTED STOCK UNIT GRANT NOTICE AND AGREEMENT

To: Hamid Erfanian (referred to herein as “Grantee” or “you”)

WHEREAS, Enzo Biochem, Inc. (the “Company”) desires to employ the Grantee as its Chief Executive Officer;

WHEREAS, in an Executive Employment Agreement dated October 14, 2021 (the “Employment Agreement”), the Company has agreed to grant the Grantee an inducement restricted stock unit (“RSU”) award for 260,000 shares of the common stock of the Company, par value $0.01 (“Common Stock”); and

WHEREAS, such RSUs will be granted on the terms and conditions set forth herein and the Grantee finds such terms and conditions to be acceptable.

NOW, THEREFORE, in consideration of the promises and of the services performed and to be performed by the Grantee, the Company is pleased to confirm that you have been granted RSUs, effective November 8, 2021 (the “Grant Date”), subject to the terms and conditions set forth herein. Except as specifically provided to the contrary under this Inducement Restricted Stock Unit Grant Notice and Agreement (this “Agreement”), this Award shall be construed and administered in accordance with the Enzo Biochem, Inc. 2011 Incentive Plan (the “Plan”), the terms of which are hereby incorporated by reference. The Award subject to this Agreement shall not be charged against the Plan’s share reserve and is being granted outside of the Plan as an inducement award under pertinent New York Stock Exchange regulations.

1. Acceptance of Terms and Conditions. To be eligible to receive this Award, you must acknowledge and accept this Award within 75 days after the Grant Date in accordance with procedures established by the Company. By accepting this Agreement, you agree to be bound by the terms and conditions herein, the Plan and any and all conditions established by the Company in connection with Awards issued under the Plan, and you further acknowledge and agree that this Award does not confer any legal or equitable right (other than those rights constituting the Award itself) against the Company or any Subsidiary directly or indirectly, or give rise to any cause of action at law or in equity against the Company or any Subsidiary. If you do not accept this Award in accordance with the procedures outlined in this Paragraph and within the 75-day period described above, the Award will be cancelled and forfeited. By accepting this Agreement, you also acknowledge that you are fluent in the English language and have reviewed and understand the terms and conditions of this Agreement and the Plan.

2. Grant of RSU Award. Subject to the restrictions, limitations, terms and conditions specified in the Plan and this Agreement, the Company has granted you as of the Grant Date RSUs for 260,000 shares of Common Stock. Except as provided in the Plan or the Employment Agreement, these RSUs will remain restricted until the end of each applicable vesting date set forth below (each, a “Vesting Date”). Prior to the delivery of the RSUs, the RSUs are not transferable by the Grantee by means of sale, assignment, exchange, pledge, or otherwise. For each of the below-stated Vesting Dates on which you continue to be employed by the Company or any of its Subsidiaries (collectively, the “Enzo Companies”), you will vest in the below-stated percentage of the total number of RSUs awarded in this Agreement, until you are 100% vested:

3. Dividend Equivalents. Subject to the restrictions, limitations and conditions described in the Plan, dividend equivalents will accrue with respect to the RSUs granted hereunder at the same time and in the same amount as cash dividends are paid to owners of Common Stock. Interest will be credited on accrued dividend equivalents. Dividend equivalent balances will vest on the same Vesting Date as the associated RSUs, and will be distributed in cash within 30 days thereafter except as provided herein.

4. Distribution of the RSUs. Except as otherwise provided in the Plan or the Employment Agreement, upon each Vesting Date specified in Paragraph 2, shares of Common Stock equal to the vested RSUs will be distributed to you. However, no stock certificates will be issued with respect to any shares of Common Stock. Common Stock ownership shall be kept electronically in your name, or in your name and in the name of another person of legal age as joint tenants with right of survivorship, as applicable. You are personally responsible for the payment of all taxes related to distribution. To the extent that the Company is required to withhold federal, state, local or foreign taxes or other amounts in connection with the payment of Common Stock or any other payment to you or on your behalf or any other payment or vesting event under this Agreement, and the amounts available to the Company for such withholding are insufficient, it shall be a condition to the obligation of the Company to make any such delivery or payment that you make arrangements satisfactory to the Company for payment of the balance of such taxes or other amounts required to be withheld. Unless otherwise determined by the Committee, such withholding requirement shall be satisfied by retention by the Company of a portion of the Common Stock to be delivered to you. The Common Stock so retained shall be credited against such withholding requirement at the Fair Market Value (as defined in the Plan) of such Common Stock on the date the applicable benefit is to be included in your income. You may elect to have the Company withhold an additional amount up to the maximum statutory amount in accordance with Company procedures. In no event will the Fair Market Value of the Common Stock to be withheld and/or delivered pursuant to this Paragraph 4 to satisfy applicable withholding taxes exceed the maximum amount of taxes required to be withheld.

5. Termination of Employment and Change in Control.  Notwithstanding anything contained in this Agreement to the contrary, Sections 2.3 and 5 of the Employment Agreement shall apply to the RSUs.  Upon the occurrence of a “Change in Control,” Section 8 of the Plan shall apply to the RSUs to the extent determined by the Committee in its sole discretion and without any requirement that Grantee be treated consistently with participants under the Plan.

6. Forfeiture/Right of Offset. Notwithstanding anything contained in this Agreement to the contrary, if you engage in any activity inimical, contrary or harmful to the interests of the Company or any Subsidiary, including but not limited to any violations of the terms of the Employment Agreement or the Plan (collectively referred to as “wrongful conduct”), then (i) RSUs, to the extent they remain subject to restriction, shall terminate automatically, (ii) you shall return to the Company all shares of Common Stock that you have not disposed of that were delivered pursuant to this Agreement within a period of one year prior to the date of the commencement of such wrongful conduct, reduced by a number of shares equal to the quotient of (A) any taxes paid in countries other than the United States with respect to the vesting or delivery of the RSUs covering such shares that are not otherwise eligible for refund from the taxing authority divided by (B) the Fair Market Value of a share of Common Stock on the date of the return of such shares, and (iii) with respect to any shares of Common Stock that you have disposed of that were delivered pursuant to this Agreement within a period of one year prior to the date of the commencement of such wrongful conduct, you shall pay to the Company in cash any financial gain you received with respect to such shares. For purposes of this Paragraph 6 and Paragraph 16 below, financial gain shall equal the Fair Market Value of a share of Common Stock on the applicable RSU delivery date, multiplied by the number of shares of Common Stock delivered with respect to the RSUs on that date, reduced by any taxes paid in countries other than the United States with respect to such vesting and which taxes are not otherwise eligible for refund from the taxing authorities. By accepting this Agreement, you consent to and authorize the Company to deduct any amounts you owe to the Company under this Paragraph from any amounts payable by the Company to you for any reason. This right of set-off is in addition to any other remedies the Company may have against you for your breach of this Agreement. In addition, by accepting this Agreement, you consent to and authorize the Company to deduct any amounts you owe to the Company for any reason from any amounts payable by the Company to you under this Agreement.

The Grantee acknowledges and agrees that this Agreement and the Award described herein (and any settlement thereof) are also subject to the terms and conditions of Company’s clawback policy as may be in effect from time to time specifically to implement Section 10D of the Exchange Act and any applicable rules or regulations promulgated thereunder (including applicable rules and regulations of any national securities exchange on which the Common Stock may be traded) (the “Compensation Recovery Policy”), and that relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of the Compensation Recovery Policy from and after the effective date thereof.

Notwithstanding anything in this Agreement to the contrary, you shall not be restricted from: (i) disclosing information that is required to be disclosed by law, court order or other valid and appropriate legal process; provided, however, that in the event such disclosure is required by law, you shall provide the Company with prompt notice of such requirement so that the Company may seek an appropriate protective order prior to any such required disclosure by you; or (ii) reporting possible violations of the laws of your country or of United States federal, state, or local law or regulation to any governmental agency or commission (each a “Government Agency”), filing a charge or complaint with the Equal Employment Opportunity Commission or any other Government Agency, participating in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, or making other disclosures that are protected under the whistleblower provisions of the laws of your country or of United States federal, state, or local law or regulation. In the event of (ii), you shall not need the prior authorization of the Company to make any such reports or disclosures, you shall not be required to notify the Company that you have made such reports or disclosures, and you acknowledge that you have waived your right to receive any monetary payment from the Company in connection with any such reports or disclosures or any ensuing charge or investigation.

You are hereby notified that under the Defend Trade Secrets Act: (i) no individual will be held criminally or civilly liable under federal or state trade secret law for disclosure of a trade secret (as defined in the Economic Espionage Act) that is: (A) made in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and made solely for the purpose of reporting or investigating a suspected violation of law or (B) made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal so that it is not made public; and (ii) an individual who pursues a lawsuit for retaliation by an employer for reporting a suspected violation of the law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal, and does not disclose the trade secret, except as permitted by court order.
