Exhibit 10.12

EXECUTIVE EMPLOYMENT AGREEMENT

THIS AGREEMENT is entered into this 27^th day of November, 2013 by and between CohBar, Inc. (the “Company”) and Jeff Biunno (“You”) in order to provide the general terms of your employment with the Company:

The Company recognizes that you will be performing your job duties primarily from your home. Given this arrangement, you agree to maintain safe conditions in your home office and to practice the same safety habits in your home office as though you work at the Company’s office. All job-related safety incidents or injuries must be promptly reported to the Company. In addition, you will be required to have equipment and software that meets any security standards set by the Company from time to time. The parties agree that the cost and expense of all equipment and software and any updates thereto shall be borne by the Company.

You also agree to abide by any employment guidelines or policies adopted by the Company and provided to you in writing from time to time, including those in any Company handbook as adopted or updated from time to time, recognizing that these policies may be amended and/or new ones implemented.

Your employment with the Company is “at-will.” Accordingly, both you and the Company remain free at all times to terminate the employment relationship, with or without cause, immediately upon written notice to the other party. Notwithstanding the foregoing, if your employment is terminated by the Company without Cause (as defined below) prior to the completion of your first six (6) months of service with the Company, the Company will continue to pay your base salary through April 30, 2014 (“Salary Continuation”).

In addition, if you are terminated by the Company without Cause then, in addition to any Salary Continuation and in lieu of any further salary, bonus, benefits or other payments for periods subsequent to the date of notice of termination (the “Termination Date”), the Company shall pay you severance (“Severance”) in an aggregate gross amount equal to 50% of your then current annual base salary. Severance shall be payable at regular intervals in accordance with the Company’s normal payroll processes over a period of six (6) months from the Termination Date (the “Severance Period”) and shall be subject to normal payroll deductions and withholding.

Any material breach of this Agreement or the attached Proprietary Information and Inventions Assignment Agreement (see Paragraph 9) shall immediately relieve the

Company from its obligation to pay Severance and/or Salary Continuation and entitle it to recover in full any amounts paid under this Section 2. You further recognize and agree that as a precondition to obtaining Severance and/or Salary Continuation, you must sign a Separation Agreement in a form substantially similar to the form of Separation Agreement attached as Exhibit A hereto that, among other things, releases any claims you may have against the Company. Failure to sign the Separation Agreement will relieve the Company of any obligation to pay Severance or Salary Continuation and entitle it to recover any such amounts already paid.

For purposes hereof, “Cause” means (i) any indictment or conviction for any crime or offense that in the Company’s judgment makes you unfit for continued employment, prevents you from performing your duties or other obligations or adversely affects the reputation of the Company; (ii) dishonesty or fraudulent conduct by you against the Company; (iii) willful violation of a key Company policy or this Agreement (including, but not limited to, acts of harassment, discrimination, or violence; use of unlawful drugs or drunkenness during normal work hours); (iv) dereliction of duty (e.g., failure to perform duties after warning and reasonable opportunity to correct); (v) competing with the Company, diversion of any corporate opportunity or other similar conflict of interest or self-dealing incurring to your direct or indirect benefit; (vi) intentional or negligent conduct that results in significant injury to the Company or its affiliates; or (vii) your death or disability (i.e., your inability to perform the essential job functions of the position with or without a reasonable accommodation).

You acknowledge that you have read this Agreement and that you have had an opportunity to consult with an attorney. You accept and sign this Agreement of your own free act and in full and complete understanding of its present and future legal effect.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.

Exhibit A

SEPARATION AGREEMENT AND RELEASE

This Separation Agreement and Release (the “Separation Agreement”) is entered into this                     day of                     , 20    by and between CohBar, Inc. (the “Company”) and Jeff Biunno (“You”) in order to provide the terms of your separation from the Company, and to resolve all issues that you might have in connection with your employment and separation from the Company.

In consideration of the mutual promises and undertakings contained herein, the parties agree as follows:

1. Separation. The parties agree that your separation from the Company is in the mutual benefit of both parties. Your employment with the Company will cease on                     , 20    (the “Separation Date”). All of your wages and benefits (except as otherwise provided in this Separation Agreement) will cease as of the Separation Date.

2. Consideration and Severance. The purpose of this Separation Agreement is to resolve all potential disputes you may have with the Company. You, therefore, confirm and agree that other than the payments below, no other payments are due to you. All payments described below shall be subject to usual tax and other withholdings and deductions.

As consideration for your promises under this Separation Agreement:

a. Wages. On the Company’s next regular payroll date after the Separation Date, the Company will pay you your wages, less regular withholdings, earned through the Separation Date.

b. Severance. Severance will only be provided if you are terminated without Cause (as defined in your Executive Employment Agreement). If you are eligible for severance, then ten business days following your signature on this Agreement, as long as you have not revoked this Agreement (see Paragraph 4), the Company will provide you with the severance payments discussed in Paragraph 2 of your Executive Employment Agreement.

You acknowledge and agree that neither the Company nor any of its attorneys have made any representations regarding the tax consequences of any amounts received by you pursuant to this Agreement. You agree to pay federal, state, and local taxes, if any, that are required by law to be paid by you with respect to this Agreement, including any obligation for federal income tax, social security, Medicare, or otherwise. You further agree to indemnify the Company for any claims, demands, deficiencies, assessments or recoveries by any governmental entity for any amounts claimed due on account of this Agreement or pursuant to claims made under any tax laws, including any incidental costs, expenses, or damages sustained by the Company. You further certify that you are not subject to backup withholding.

3. Insurance Benefits. All your benefits will cease as of the Separation Date, except that you may be eligible to continue insurance coverage on a fully or partially self-paid basis under COBRA.

4. Waiver and Release of Claims.

In return for the benefits conferred by this Separation Agreement, which you acknowledge exceed the amounts which you would otherwise be entitled to receive, you, on behalf of yourself and your marital community, and your heirs, executors, administrators and assigns, hereby release in full and forever discharge, acquit and hold harmless the Company, including any of the Company’s past or present parents, subsidiaries or otherwise affiliated corporations, partnerships, or other business entities or enterprises, and all of its or their past or present affiliates, related entities, partners, subsidiaries, insurers, predecessors, successors, assigns, directors, officers, shareholders, members, investors, attorneys, accountants, representatives, agents and employees (these entities/persons together with Company are collectively referred to as “Associated Persons”), from any and all claims, causes of action, suits, liabilities, demands, damages, including damages for pain and suffering and emotional harm, charges, controversies, expenses and obligations of every nature, character or kind, whether contractual, monetary, or non-monetary in nature that arise at any time prior to the date you sign this Agreement (collectively “Claims”). This release includes all Claims whether they are now known to you or are later discovered by you, suspected or unsuspected, and regardless of whether the Claims are mature or contingent, including, but not limited to, any Claims which in any manner or fashion arise from or relate to your employment with us, any contractual agreements between you and us, or your separation from employment with us, including without limitation any claims for damages, equitable relief, attorney fees or costs. This release specifically includes, but is not limited to, all Claims arising from or relating to your employment with the Company or your provision of services to the Company or the termination of such employment or services. You do not waive or release any claims or rights that may arise after the date you sign this Agreement, nor does this waiver and release preclude either party from filing a lawsuit for the exclusive purpose of enforcing its rights under this Agreement.

This release includes, but is not limited to, any Claims that you might have for reinstatement, reemployment, or for additional compensation, including without limitation any Claim for any past, current or future wages, bonuses, commissions, fees, payments, incentive payments, sick leave pay-out, extended illness bank pay-out, severance pay, expenses, salary, unvested stock options, vacation pay, fees or costs, losses, penalties or benefits. Without limitation, it applies to Claims for damages or other personal remedies that you might have under any federal, state and/or local law, statutory, regulatory or common, dealing with employment, tort, contract, wage and hour, civil rights or any other matters, including, by way of example and not limitation, applicable civil rights laws, retaliation, federal and state whistleblower laws, Title VII of the Civil Rights Act of 1964, the Post-War Civil Rights Act of 1964, the Post-War Civil Rights Acts (42 USC Sections 1981-1988), the Civil Rights Act of 1991, the Americans with Disabilities Act, the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, the Family and Medical Leave Act, the Fair Labor Standards Act, the National Labor Relations Act, the Employee Retirement Income Security Act (excluding COBRA), the Vietnam Era Veterans Readjustment Assistance Act, the Fair Credit Reporting Act, the Occupational Safety and Health Act, the Sarbanes-Oxley Act of 2002, the Health Insurance Portability and Accountability Act of 1995, the Rehabilitation Act of 1973, the Equal Pay Act of 1963, Executive Order 11246, Washington’s Law Against Discrimination, Chapter 49.60 RCW, and

Washington’s Minimum Wage Act, Chapter 49.46 RCW, and any regulations under such laws. This release further applies to any Claims or right to personal damages, benefits or other personal legal or equitable remedies that you may have as a result of filing any complaint, charge or other action before any administrative agency.

You have read and intend to waive Section 1542 of the Civil Code of the State of California, which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN [HIS] FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY [HIM] MUST HAVE MATERIALLY AFFECTED [HIS] SETTLEMENT WITH THE DEBTOR.

You understand that Section 1542 gives you the right not to release existing claims of which you are not aware or do not know or suspect unless you voluntarily choose to waive this right. Having been so apprised, you nevertheless hereby voluntarily elect to and do waive all rights and benefits described in Section 1542 and all similar provisions of law of other jurisdictions to the full extent that you might lawfully waive each and all such rights and benefits pertaining to the subject matter released herein and elect to assume all risks for claims that now do or may exist in your favor, whether known or unknown, suspected or unsuspected. In connection with such waiver and relinquishment, you hereby acknowledge that you are aware that you may hereafter discover facts in addition to or different from those you now know or believe to be true with respect to the subject matter of this Agreement, that it is your intention hereby fully, finally and forever to settle and resolve matters released herein, disputes, differences, known or unknown, suspected or unsuspected, which now exist, may exist, or heretofore have existed and that in furtherance of such intention, your release as given herein shall be and remain in effect as a full and complete general release notwithstanding the discovery of the existence of any such additional or different facts.

YOU ACKNOWLEDGE AND AGREE THAT THROUGH THIS RELEASE YOU ARE GIVING UP ALL RIGHTS AND CLAIMS OF EVERY KIND AND NATURE WHATSOEVER, KNOWN OR UNKNOWN, CONTINGENT OR LIQUIDATED, THAT YOU MAY HAVE AGAINST THE COMPANY AND ASSOCIATED PERSONS ARISING PRIOR TO THE DATE YOU SIGN THE AGREEMENT.

ADEA Waiver. You acknowledge that your waiver and release hereunder of any rights you may have under the Age Discrimination in Employment Act of 1967 (ADEA), as amended by the Older Workers Benefit Protection Act, is knowing and voluntary. You certify that you have read and understand the provisions of this release of claims. You and the Company agree that this waiver and release does not apply to any rights or claims that may arise under ADEA after the date this Separation Agreement is executed. You acknowledge that the severance benefits provided in this Separation Agreement are specifically linked to your ADEA claim release and that you would not receive the same benefits absent your agreement to provide such a release. You acknowledge that you have been advised by this writing, as required by the Older Workers Benefit Protection Act, that (a) you should consult with an attorney prior to executing this Separation Agreement; (b) you have twenty-one (21) days to consider this Separation Agreement (although you may, by your own choice, execute this Separation Agreement earlier); (c) you have seven (7) days following the execution of this Separation Agreement by you to revoke the Separation Agreement; and (d) this Separation Agreement shall not be effective until the date upon which this revocation period has expired. If you wish to revoke the Separation Agreement, you must send written notice of your revocation to the attention of                     , to be received within seven (7) days following your signature on this Separation Agreement.

The only Claims excluded from this release are claims relating to breach or enforceability of this Separation Agreement and your right to file a complaint, charge or other action with a governmental agency. With regard to governmental agency complaints, however, you understand and agree that you are expressly waiving any right to obtain monetary damages or any other relief that provides personal benefit resulting from the agency claim. This waiver and release is effective to the full extent the law permits you to release your individual claims. It does not affect reimbursement rights you may currently possess under any health insurance coverage or accrued rights you may have under any retirement plan after termination.

5. No Claims. You agree to inform us if you have filed any released Claims against the Company, including any Associated Person, except you are not required to inform us of the filing of any claims that are explicitly excluded from paragraph 4. You further agree that you will not file any Claims that have been released under paragraph 4.

6. Non-Admission of Liability. This Separation Agreement is not an admission by either party of any liability or of any violation by the Company or Associated Persons of any law.

7. Return of Property. You will return to the Company all of its property in your possession or control by the Separation Date. You also warrant that you have provided the Company with copies of all contracts, agreements, obligations or promises into which you have entered as the Company’s representative.

8. Nondisparagement. The Company is entering into this Separation Agreement, in part, to ensure an amicable relationship with you. You, therefore, agree not to make negative or disparaging comments, publicly or privately, concerning the Company, its products or services, or Associated Persons.

9. Confidentiality. Since the Company does not provide severance to all employees, you agree to keep the terms and conditions of this Separation Agreement, including any payments made hereunder, strictly confidential. You further agree not to disclose such terms or conditions in any manner whatsoever, unless required by law; provided that you may share the provisions with your immediate family, attorneys, health care providers, and tax and financial advisors. In such cases you shall take reasonable precaution to ensure that such information will be protected within the letter and spirit of this Separation Agreement. You agree to instruct any person with whom you share the information pursuant to this Paragraph to likewise keep confidential the terms of this Separation Agreement.

You are also reminded that the Proprietary Information and Inventions Assignment Agreement signed by you on                     , 2013 remains in effect after your employment with the Company ends.

10. Entire Agreement. This Separation Agreement, your Executive Employment Agreement, and the Proprietary Information and Inventions Assignment Agreement express the full and complete agreement between the parties regarding the separation of your employment from the Company. The terms of this Separation Agreement are contractual and not a mere recital of promises. There is no understanding or agreement to make any payment or perform any act other than what is provided for in this document. Any modification of this Separation Agreement shall not be effective unless it is in writing and signed by all parties to this Separation Agreement.

11. Waiver. No waiver of any provision of this Separation Agreement shall constitute a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver. No waiver shall be binding unless executed in writing by the party making the waiver.

12. Binding Effect. All rights, remedies and liabilities given to or imposed upon the parties by this Separation Agreement shall extend to, inure to the benefit of and bind the parties and their respective heirs, personal representatives, administrators, successors and permitted assigns.

13. Severability. In the event any provision or portion of this Separation Agreement is held to be unenforceable or invalid by any court of competent jurisdiction, the remainder of this Separation Agreement shall remain in full force.

14. Enforcement. In the event there is a breach of this Separation Agreement or non-compliance with a term contained herein by either party, the non-defaulting or substantially prevailing party shall be entitled to recovery of any reasonable costs, including attorneys’ fees and expenses, incurred in enforcing this Separation Agreement.

15. Governing Law and Venue. This Separation Agreement shall be governed in accordance with the laws of the State of California, without regard to its conflict of law principles. Any suit in connection with this Separation Agreement shall be brought and maintained in the federal or state courts in Los Angeles County, California. The parties irrevocably submit to the jurisdiction of such courts for the purpose of such suit and irrevocably waive, to the fullest extent permitted by law, any objection it may have to the venue and any claim that the forum is inconvenient.

16. Voluntary Agreement. The Company encourages you to discuss this Agreement with financial and legal counsel of your choice. You acknowledge that you have had an opportunity to do so and have read the entire Agreement. You further acknowledge that you are voluntarily executing this Separation Agreement with the full and complete understanding of the terms of this Separation Agreement and its present and future legal effect, without any undue pressure or coercion from the Company.

IN WITNESS WHEREOF, the parties have executed this Separation Agreement voluntarily and free of all duress or any other encumbrance as of the date and year set forth above.
