PERFORMANCE AWARD (U.S. EMPLOYEES)

Summary of Restricted Share Unit Award Grant

Meridian Bioscience, Inc., an Ohio corporation (the “Company”), grants to the Grantee named below, in accordance with the terms of the Meridian Bioscience, Inc. 2012 Stock Incentive Plan (the “Plan”) and this Restricted Share Unit Award Agreement (the “Agreement”), the following number of Restricted Share Units of the Company (the “Restricted Units”), on the Grant Date set forth below:

Terms of Agreement

1. Grant of Restricted Share Unit Awards. Subject to and upon the terms, conditions, and restrictions set forth in this Agreement and in the Plan, the Company hereby grants to the Grantee as of the Grant Date, the total number of Restricted Units set forth above. The Restricted Units shall be credited in a book entry account established for the Grantee until payment in accordance with Section 4 hereof.

2. Vesting of Restricted Units.

(a) Except as otherwise provided in this Agreement, this grant of Restricted Units shall not vest and shall become void and be of no further effect at the time net earnings for Meridian’s fiscal year ended September 30, 2016 are determined and such earnings are released to the public unless such net earnings (the “Actual Earnings”) exceed $******, subject to treatment of certain items as defined in Item A of the 2016 Officers’ Performance Compensation Plan (Corporate Incentive Bonus Plan) (the “Earnings Target”). If the Actual Earnings exceed the Earnings Target, this grant of Restricted Units shall continue in full force and effect in accordance with the terms and conditions of the Plan and this Agreement and such Restricted Units shall vest 25% per year from the date of grant on the respective Vesting Dates identified above.

(b) All of the Restricted Units shall vest in full immediately upon the occurrence of any of the following prior to any determination and release to the public of earnings as described in Section 2(a): (i) the Grantee dies while in the employ of the Company; (ii) the Grantee has a Disability; or (iii) there is an event described in Section 2(g) of the Plan (“Section 2(g) Change in Control”). For the avoidance of doubt, all of the Restricted Units that vest in full upon the occurrence of an event described in (i), (ii) or (iii) in the immediately preceding sentence prior to any determination and release to the public of earnings as described in Section 2(a) shall remain vested and shall not be forfeited or cancelled even if the Earnings Target exceeds the Actual Earnings.

- 1 -

(c) In no event shall any of the Restricted Units vest if Grantee’s Retirement occurs prior to March 31, 2015. For the avoidance of doubt, if Grantee’s Retirement occurs prior to March 31, 2016, Grantee shall forfeit the Restricted Units even if the Actual Earnings exceed the Earnings Target.

(d) If Grantee’s Retirement occurs after March 31, 2016 but before any determination and release to the public of earnings as described in Section 2(a), Restricted Units shall vest upon, and only upon, the later determination and release to the public that the Actual Earnings exceed the Earnings Target.

(e) In the event that after the determination and release to the public as described in Section 2(a) the Actual Earnings exceed the Earnings Target Grantee’s employment with the Company is terminated due to the Grantee’s death, Disability, or Retirement including separation from employment, all of the Restricted Units shall vest in full upon Grantee’s death, Disability or Retirement, as the case may be.

(f) In the event of the determination and release to the public that the Actual Earnings exceed the Earnings Target, the Committee may, in its sole discretion, accelerate the time at which the Restricted Units become vested and nonforfeitable on such terms and conditions as it deems appropriate in accordance with the terms and conditions of the Plan, provided such acceleration does not result in an impermissible acceleration of payments under Section 409A of the Code.

3. Forfeiture of Restricted Units.

(a) The Restricted Units that have not yet vested pursuant to Section 2 shall be forfeited automatically without further action or notice if the Grantee ceases to be employed by the Company other than as provided in Section 2(b) 2(d), 2(e) or (f) hereof.

(b) The Grantee hereby acknowledges that in order for the Restricted Units to vest, Grantee must, prior to the first Vesting Date identified on the first page hereof under “Summary of Restricted Share Unit Award Grant”, (i) accept the Restricted Units online or by telephone in accordance with the procedures established by the Company and Merrill Lynch, and; (ii) open a Merrill Lynch brokerage account through the system maintained on behalf of the Company. If the Grantee has not completed both of the tasks prior to the first Vesting Date identified on the first page hereof under “Summary of Restricted Share Unit Award Grant”, the Restricted Units shall be forfeited as of such date.

4. Payment.

(a) Except as otherwise provided in this Agreement, the Company shall deliver to the Grantee one share of its common stock (“Share”) for each vested Restricted Unit within thirty (30) days following the earlier of:

(i) the Vesting Dates identified on the first page hereof under “Summary of Restricted Share Unit Award Grant”;

(ii) the date of the Grantee’s death;

(iii) the date of the Grantee’s Disability, provided such Disability also constitutes a “disability” within the meaning of Section 409A of the Code with respect to a Grantee whose Restricted Units are subject to Section 409A of the Code;

(iv) the date of Grantee’s termination of employment with the Company as a result of Retirement or a Change in Control event described in Section 2(g)(i) or (ii) of the Plan, provided such termination of employment also constitutes a “separation from service” within the meaning of Section 409A of the Code with respect to a Grantee whose Restricted Units are subject to Section 409A of the Code; or

- 2 -

(v) the date of an event described in Section 2(g)(iii) or (iv) of the Plan, provided such event also constitutes a “change in control event” within the meaning of Section 409A of the Code with respect to a Grantee whose Restricted Units are subject to Section 409A of the Code.

If the Grantee is a “specified employee” within the meaning of Section 409A of the Code on the date of the Grantee’s separation from service and the Grantee’s Restricted Units are subject to Section 409A of the Code, then payment under (iv) above shall be made on the first day of the seventh month following the Grantee’s separation from service, or, if earlier, the date of the Grantee’s death.

(b) The Company’s obligations with respect to the Restricted Units shall be satisfied in full upon the delivery of its Shares pursuant to Section 4(a) herein.

5. Transferability. The Restricted Units may not be transferred and shall not be subject in any manner to assignment, alienation, pledge, encumbrance or charge, until all restrictions are removed or have expired, unless otherwise provided under the Plan. Any purported Transfer or encumbrance in violation of the provisions of this Section 5 shall be void, and the other party to any such purported transaction shall not obtain any rights to or interest in such Restricted Units.

6. Voting and Other Rights. The Grantee will not have any rights of a shareholder of the Company with respect to the Restricted Units until the delivery of the underlying Shares. The obligations of the Company under this Agreement will be merely that of an unfunded and unsecured promise of the Company to deliver Shares in the future, and the rights of the Grantee will be no greater than that of an unsecured general creditor. No assets of the Company will be held or set aside as security for the obligations of the Company under this Agreement.

7. Dividend Equivalent Payment Rights. The Grantee shall possess dividend equivalent payment rights with respect to the Restricted Units granted pursuant to this Agreement as of the Grant Date. Any dividend equivalent payment on the Restricted Units shall be based on the number of Restricted Units credited to the Grantee as of the dividend record date and such credited dividend equivalent payment amount shall be paid in accordance with quarterly dividend declarations by the Board of Directors on the Company’s common stock.

8. Continuous Employment. Unless otherwise specified by the Plan, for purposes of this Agreement, the continuous employment of the Grantee with the Company shall not be deemed to have been interrupted, and the Grantee shall not be deemed to have ceased to be an employee of the Company, by reason of the transfer of his employment among the Company or a leave of absence approved by the Committee.

9. No Employment Contract. Nothing contained in this Agreement shall confer upon the Grantee any right with respect to continuance of employment by the Company, nor limit or affect in any manner the right of the Company to terminate the employment or adjust the compensation of the Grantee.

10. Relation to Other Benefits. Any economic or other benefit to the Grantee under this Agreement or the Plan shall not be taken into account in determining any benefits to which the Grantee may be entitled under any profit-sharing, retirement or other benefit or compensation plan maintained by the Company and shall not affect the amount of any life insurance coverage available to any beneficiary under any life insurance plan covering employees of the Company.

11. Taxes and Withholding. To the extent that the Company is required to withhold any federal, state, local, foreign or other tax in connection with the Restricted Units or dividend equivalent payments thereon pursuant to this Agreement, it shall be a condition to earning the award that the Grantee make arrangements satisfactory to the Company for payment of such taxes required to be withheld. With respect to payments under Section 4 herein, the Committee may, in its sole discretion, require the Grantee to satisfy such required withholding obligation by surrendering to the Company a portion of the Shares earned by the Grantee

- 3 -

hereunder, and the Shares so surrendered by the Grantee shall be credited against any such withholding obligation at the Fair Market Value of such Shares on the date of surrender.

12. Adjustments. The number and kind of Shares deliverable pursuant to a Restricted Unit are subject to adjustment as provided in Section 8 of the Plan.

13. Compliance with Law. While the Company shall make reasonable efforts to comply with all applicable federal and state securities laws and listing requirements with respect to the Restricted Units or Shares that may be delivered pursuant to Section 4 herein, the Company shall not be obligated to deliver any Restricted Units or Shares pursuant to this Agreement if the delivery thereof would result in a violation of any such law or listing requirement.

14. Amendments. Subject to the terms of the Plan, the Committee may modify this Agreement upon written notice to the Grantee. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto; provided, however, no amendment of the Plan or this Agreement shall adversely affect the rights of the Grantee under this Agreement without the Grantee’s consent unless the Committee determines, in good faith, that such amendment is required for the Agreement to either be exempt from the application of, or comply with, the requirements of Section 409A of the Code, or as otherwise may be provided in the Plan.

15. Section 409A of the Code. It is intended that the Restricted Units shall be exempt from the application of, or comply with, the requirements of Section 409A of the Code. The terms of this Agreement shall be construed, administered, and governed in a manner that effects such intent, and the Committee shall not take any action that would be inconsistent with such intent. Without limiting the foregoing, the Restricted Units shall not be deferred, accelerated, extended, paid out, settled, adjusted, substituted, exchanged or modified in a manner that would cause the award to fail to satisfy the conditions of an applicable exception from the requirements of Section 409A of the Code or otherwise would subject the Grantee to the additional tax imposed under Section 409A of the Code.

16. Severability. In the event that one or more of the provisions of this Agreement shall be invalidated for any reason by a court of competent jurisdiction, any provision so invalidated shall be deemed to be separable from the other provisions hereof, and the remaining provisions hereof shall continue to be valid and fully enforceable.

17. Relation to Plan. This Agreement is subject to the terms and conditions of the Plan. This Agreement and the Plan contain the entire agreement and understanding of the parties with respect to the subject matter contained in this Agreement, and supersede all prior written or oral communications, representations and negotiations in respect thereto. In the event of any inconsistency between the provisions of this Agreement and the Plan, the Plan shall govern except with respect to Section 1(a) of this Agreement. Capitalized terms used herein without definition shall have the meanings assigned to them in the Plan. The Committee acting pursuant to the Plan, as constituted from time to time, shall, except as expressly provided otherwise herein, have the right to determine any questions which arise in connection with the grant of the Restricted Units.

18. Successors and Assigns. Without limiting Section 5, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors, administrators, heirs, legal representatives and assigns of the Grantee, and the successors and assigns of the Company.

19. No Advice Regarding Award. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Grantee’s participation in the Plan or the acquisition or sale of the underlying securities. The Grantee is hereby advised to consult with the Grantee’s personal tax, legal or financial advisors regarding the decision to participate in the Plan before taking any action related to the Plan.
