Form of Severance Letter Agreement

Subject to the your obligations under this Agreement, you are eligible to receive “Severance Benefits” as set forth in this paragraph:

In the event your employment is terminated by the Company for a reason other than for Cause (as defined below) or by you for Good Reason (as defined below), the Company will pay you the sum of [•] Base Pay and your annual FY Target Bonus opportunity in effect on your last day of employment (“Separation Date”). In addition, the Company will pay your COBRA benefit premiums until the earlier of twelve (12) months from your Separation Date or until the date on which you become eligible for other health insurance benefits.

In the event your employment is terminated by the Company for a reason other than for Cause or by you for Good Reason, within twelve (12) months following a Change of Control (as defined below) of the Company, (i) the Company will pay you the sum of [•] Base Pay and your annual FY Target Bonus opportunity and (ii) all of your unvested stock options, restricted stock, and/or other equity awards will vest on your Separation Date. Such vested awards that were granted as restricted stock will be free of restrictions and such vested awards that were granted as options will remain exercisable for a period of three (3) months following Separation Date. In addition, the Company will pay your COBRA benefit premiums until the earlier of twelve (12) months from your Separation Date or until the date on which you become eligible for other health benefits.

Cessation of your employment due to your death, disability, or resignation without Good Reason will disqualify you from receiving the Severance Benefits.

As a condition of receiving the Severance Benefits, you must execute, not revoke, and remain in compliance with the waiver and release in the form attached as Exhibit A (the “Waiver and Release Agreement”). The Company will pay the Base Pay and COBRA components of the Severance Benefits in installments on its regular payroll dates during the severance period, subject to all required withholding. The Target Bonus component of the Severance Benefits will be paid in full in the first Severance Benefit payment. The payments will commence on the first regular payroll date after the Waiver and Release Agreement becomes irrevocable in accordance with its terms, with the first payment covering the time period from the Separation Date through such payment date.

If the Company determines you have engaged in “Detrimental Activity” (as defined below) during the period in which you are receiving Severance Benefits (i) payment of any remaining Severance Benefits will cease immediately and (ii) you will be obligated to repay to the Company all benefits, including the Severance Benefits set forth in paragraph 1, previously paid to under this Agreement within thirty (30) days of a final adjudication that you have engaged in such Detrimental Activity or other final disposition of the matter between the parties. The repayment of the Severance Benefits as required in this paragraph 4 will not affect the validity of any other written agreements between you and the

Company, including the Waiver and Release Agreement. If you become reemployed by the Company before you receive the full Severance Benefits under this Agreement, any remaining benefits will be forfeited as of the date of your re-employment.

“Person” mean an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act.

“Target Bonus” means the annual target bonus opportunity you are eligible to receive from the Company for the year in which the Separation Date occurs; provided, if your employment terminates due to Good Reason based, in part or whole, on a reduction in your annual target bonus opportunity, the annual target bonus opportunity will be the annual target bonus opportunity in effect immediately before such reduction.

It is intended that the Agreement (and any payments) will be exempt from or in compliance with Internal Revenue Code Section 409A (“Section 409A”), and this Agreement (and any payments) will be interpreted and construed on a basis consistent with such intent. The term “termination of employment” and similar terms relating to your termination of employment mean a “separation from service” as that term is defined under Section 409A. Each payment made under the Agreement will be treated as a separate payment for purposes of Section 409A. If you are a “specified employee” (as that term is used in Section 409A) on the date your separation from service becomes effective, any benefits payable under the Agreement that constitute non-qualified deferred compensation under Section 409A will be delayed until the earlier of (a) the business day following the six-month anniversary of the date your separation from service becomes effective, and (b) the date of your death, but only to the extent necessary to avoid such penalties under Section 409A. On the earlier of (1) the business day following the six-month anniversary of the date your separation from service becomes effective, and (2) your death, the Company will pay you in a lump sum the aggregate value of the non-qualified deferred compensation that the Company otherwise would have paid you prior to that date. The Agreement (and any payments) can be amended in any respect deemed necessary or desirable (including retroactively) by the Company with the intent to preserve exemption from or compliance with Section 409A. The preceding will not be construed as a guarantee of any particular tax effect for payments hereunder. A participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on such person in connection with this Agreement (including any taxes and penalties under Section 409A), and the Company will not have any obligation to indemnify or otherwise hold a participant harmless from any or all of such taxes or penalties.

Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal, or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity,

illegality, or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed, and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

This Agreement embodies the complete agreement and understanding between you and the Company regarding this subject matter and supersedes and preempts all prior understandings, agreements or representations between you and the Company regarding such subject matter.

The provisions of this Agreement can be amended or waived only with the prior written consent of the Company and you, and no course of conduct or course of dealing will affect the validity, binding effect, or enforceability of this Agreement or be deemed to be an implied waiver of any provision of this Agreement. You cannot assign any of your rights under this Agreement, except with the prior written consent of the Company. Any purported assignment of rights in violation of this section is void. The Company cannot assign this Agreement without your prior written consent; provided, however, that the Company can assign its rights and obligations under this Agreement without your consent in the event that the Company effects a reorganization, consolidation, or merger, or transfer of all or substantially all of its properties, stock, or assets to another entity. This Agreement is binding on the Company’s successors, assigns, or acquiror of all or substantially all of the assets of the Company.

This Agreement is governed by Michigan law. Each party irrevocably submits to the exclusive jurisdiction of the state or federal courts located in Michigan for the purposes of any action, litigation, or proceeding of any kind whatsoever arising out of this Agreement or any transaction contemplated hereunder or thereunder.

Each party irrevocably and unconditionally waives any objection to the laying of venue of any action, litigation, or proceeding arising out of this Agreement or the transactions contemplated by this Agreement in state or federal courts located in Michigan, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, litigation, or proceeding brought in any such court has been brought in an inconvenient forum. EACH PARTY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF SUCH PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE, AND ENFORCEMENT HEREOF OR THEREOF.

I, [Insert Name], in consideration of certain payments and benefits to be provided to me by Neogen Corporation (the “Company”) under that letter agreement dated [Insert Date] (the “Agreement”), which are conditioned on my signing this Release and Waiver Agreement, on my own behalf and on behalf of my heirs, executors, administrators, beneficiaries, representatives, successors, and assigns, and all others connected with or claiming through me, hereby release and forever discharge as of the date hereof the Company, its parent entity, subsidiaries, and affiliates, and all of their present and former directors, officers, members, managers, agents, employees, employee benefit plans, attorneys, consultants, predecessors, successors and assigns, and all those connected with any of them, in their official and individual capacities (collectively, the “Released Parties”), from any and all causes of action, suits, rights and claims, demands, damages and compensation, whether at law or in equity, whether now known or unknown, suspected or unsuspected, contingent or otherwise, which I now have or ever have had against the Released Parties, or any of them, including but not limited to those in any way related to, connected with or arising out of my employment and/or other relationship with the Company, the termination of such employment and/or other relationship, or pursuant to Title VII of the Civil Rights Act, the Americans With Disabilities Act, the Family and Medical Leave Act, the Age Discrimination in Employment Act (as amended by the Older Workers Benefit Protection Act), the Employee Retirement Income Security Act, the wage and hour, wage payment and/or fair employment practices laws and statutes of the state or states in which I have provided services to the Company (each as amended from time to time) and/or any other federal, state, common or local law, regulation, or other requirement (collectively, the “Claims”), and I hereby waive all such Claims.

I understand that any payments to be paid to me under the Agreement represent, in part, consideration for signing this Release and Waiver Agreement and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive the payments and benefits specified in the Agreement unless I execute this Release and Waiver Agreement and do not revoke this General Release within the time period permitted hereafter or breach this General Release.

I represent that I have made no assignment or transfer of any released Claims.

In signing this Release and Waiver Agreement, I acknowledge and intend that it will be effective as a bar to each and every one of the Claims hereinabove mentioned or implied, and I covenant not to sue or initiate any legal proceeding regarding any released Claims. I expressly consent that this General Release will be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I further agree that I am not aware of any pending charge or complaint regarding any released Claims as of the execution of this Release and Waiver Agreement.

Notwithstanding the foregoing, this Release and Waiver Agreement does not release: (a) claims for vested benefits pursuant to any Company employee welfare plan; (b) claims that may arise for indemnification and/or for coverage under any directors and officers insurance policy that the Company may maintain from time to time; (c) rights as to equity interests that have vested by their express terms and are not otherwise forfeited pursuant to their terms or any applicable plans; and/or (d) claims that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share

or participate in any monetary award resulting from the prosecution of such charge or investigation or proceeding except pursuant to a whistleblower program (including but not limited to the whistleblower program maintained by the Securities and Exchange Commission) or where my right to receive such a monetary benefit is otherwise not waivable by law.

I agree that neither this Release and Waiver Agreement, nor the furnishing of the consideration for this General Release, will be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct.

I agree that I remain bound by, and will fully comply with, any post-employment confidentiality and/or restrictive covenant obligations in favor of the Company or its Affiliates, including but not limited to those set forth in the Non-Disclosure, Non-Competition, Non-Solicitation and Property Assignment Agreement executed by me.

I have complied with my obligation to return the Company’s property and documents, without retaining copies of such Company materials.

Neither I nor the Company and/or the Released Parries will publicly defame, disparage, criticize, or otherwise speak negatively regarding the other party or its products, including through any media, social media, Facebook, Twitter, or similar mechanism. The foregoing restrictions will not apply with respect to any legally compelled testimony or any truthful communications with government agencies in the course of an investigation.

Whenever possible, each provision of this Release and Waiver Agreement will be interpreted in, such manner as to be effective and valid under applicable law, but if any provision of this Release and Waiver Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Release and Waiver Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.
