    This Separation Agreement (this “Agreement”) is made and entered into as of April 21, 2023, by and between David Baker (“Executive”) and GRI Bio, Inc. (f/k/a Vallon Pharmaceuticals, Inc.) (the “Company”). The Company and Executive are sometimes collectively referred to herein as the “Parties” and individually as a “Party”.

    1.    Separation. Executive’s employment with the Company and its affiliates terminated as of the Closing Date, as that term is defined in the Agreement and Plan of Merger among Vallon Pharmaceuticals, Inc., Vallon Merger Sub, Inc. and GRI Bio, Inc., dated as of December 13, 2022 (the “Separation Date”). By signing below, Executive hereby resigns as President and Chief Executive Officer and as a member of the board of directors of each of the Company’s affiliates, in each case as of the Separation Date. Notwithstanding the foregoing, Executive shall continue to serve as a member of the Board of Directors of the Company (the “Board”) until his successor is duly appointed or elected in accordance with the Company’s organizational documents.

2.    Payments and Benefits.

(a)    Accrued Benefits. All Company-provided benefits ceased to accrue as of the Separation Date. Executive shall be provided the earned payments and benefits set forth as the “Accrued Benefits” in Exhibit A hereto.

(b)    Separation Benefits. In consideration of, and subject to and conditioned upon Executive’s execution and non-revocation of the Release attached as Exhibit B to this Agreement (the “Release”) within 21 calendar days following the Separation Date, and the effectiveness of such Release as provided in Section 3 of this Agreement, the Company shall pay or provide to Executive the special severance payments contemplated by Section 5(c) of the Employment Agreement between Executive and the Company dated as of April 20, 2021 (the “Employment Agreement”) to which Executive is entitled upon a termination without cause (and as set forth as “Severance Payments” on Exhibit A hereto), upon the terms, and subject to the conditions, of the Employment Agreement and as summarized in Exhibit A.

(c)    Full Payment. Executive acknowledges that the payments and arrangements contained in this Agreement (including as summarized in Exhibit A) shall constitute full and complete satisfaction of any and all amounts properly due and owing to Executive as a result of his employment with the Company and its affiliates and his termination therefrom, including, without limitation, any and all amounts properly due and owing to Executive under the Employment Agreement.

3.    Release of Claims. Executive agrees that, as a condition to Executive’s right to receive the payments and benefits set forth in Section 2(b) of this Agreement, within 21 calendar days following the Separation Date (the “Release Period”), Executive shall execute and deliver the Release to the Company. If Executive fails to execute and deliver the Release to the Company during the Release Period, or if the Release is revoked by Executive or otherwise does not become effective and irrevocable in accordance with its terms, then Executive will receive only the Accrued Benefits and will not be entitled to any other payment or benefit under Section 2(b) of this Agreement.

    4.    Effect on Other Agreements.

(a)    Executive specifically acknowledges and agrees that he remains obligated to comply with Section 8 (Executive’s Covenants) and Section 10 (Cooperation) of the Employment Agreement, which provisions shall continue to apply, in accordance with their terms, on and after the Separation Date, notwithstanding Executive’s termination of employment. Executive acknowledges and agrees that this Agreement satisfies any obligation of the Company to provide written notice to Executive regarding termination of his employment pursuant to the Employment Agreement.

(b)    The Company acknowledges that it remains obligated to comply with the last two sentences of Section 13 of the Employment Agreement (relating to the payment of a bonus amount to Executive upon the achievement of Milestone #2 as defined therein), provided that the second to last sentence of Section 13 of the Employment Agreement is hereby amended by substituting “$25,000” for “$100,000” where it appears therein.

(c)    The Parties acknowledge and agree that, as of the Separation Date, Executive holds stock options to purchase shares of common stock of the Company (the “Stock Options”) under the Company’s 2018 Equity Incentive Plan (the “Equity Plan”) and the related stock option agreements (the “Option Agreements”). The Parties acknowledge and agree that all vested Stock Options as of the Separation Date shall remain outstanding and exercisable, in accordance with the terms, and subject to the conditions, of the Equity Plan and the applicable Option Agreement (and, for the avoidance of doubt, continued service by Executive on the Board shall constitute continued service with the Company for purposes of applying the post-termination exercise period under the Option Agreements). All unvested Stock Options as of the Separation Date shall be forfeited automatically and without further action or notice, as of the Separation Date.

5.    Return of Property. Executive agrees to promptly return to the Company all Company property in Executive’s possession or control and to disclose to the Company all passwords necessary or desirable to obtain access to, or that would assist in obtaining access to, any information which Executive has password-protected on any computer equipment, network or system of the Company; provided that Executive shall be permitted to retain his Company-issued computer and cellular telephone equipment (and Executive shall promptly delete all Company files therefrom).

6.    Miscellaneous.

(a)    Withholding. The Company or its affiliates, as applicable, may withhold from any amounts payable or benefits provided under this Agreement such federal, state, local, foreign or other taxes as will be required to be withheld pursuant to any applicable law or regulation (or require Executive to make arrangements satisfactory to the Company for the payment of such required withholding taxes).

(b)    Successors. This Agreement is personal to Executive and without the prior written consent of the Company will not be assignable by Executive other than by will or the laws of descent and distribution. This Agreement will inure to the benefit of and be enforceable by Executive’s surviving spouse, heirs and legal representatives.
