SUPPORT AGREEMENT
This SUPPORT AGREEMENT (this “Agreement”) is entered into as of December 13, 2022, by and between GRI Bio, Inc., a Delaware corporation (the “Company”) and the Person set forth on Schedule A hereto (the “Stockholder”).
WHEREAS, as of the date hereof, the Stockholder is the holder of the number of shares of common stock, par value $0.0001 per share (“PubCo Shares”), of Vallon Pharmaceuticals, Inc., a Delaware corporation (“PubCo”), set forth opposite the Stockholder’s name on Schedule A (all PubCo Shares and other securities of PubCo owned by the Stockholder, or hereafter issued to or otherwise acquired, whether beneficially or of record, or owned by the Stockholder prior to the termination of this Agreement, as well as shares set forth on Schedule A, being referred to herein as the “Subject Shares”);
WHEREAS, the Company, PubCo, and Vallon Merger Sub, Inc., a Delaware corporation (“Merger Sub”), propose to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), which provides, among other things, for the merger of Merger Sub with and into the Company, with the Company continuing as the surviving company (the “Merger”), upon the terms and subject to the conditions set forth in the Merger Agreement (capitalized terms used but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Merger Agreement); and
WHEREAS, as a condition to its willingness to enter into the Merger Agreement, the PubCo has required that the Stockholder, and as an inducement and in consideration therefor, the Stockholder (in the Stockholder’s capacity as a holder of the Subject Shares) has agreed to, enter into this Agreement.
NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, do hereby agree as follows:
ARTICLE I
VOTING AGREEMENT; GRANT OF PROXY
The Stockholder hereby covenants and agrees that:
1.1. Voting of Subject Shares. From and after the date hereof, at every meeting of the holders of PubCo Shares (the “PubCo Stockholders”), however called, and at every adjournment or postponement thereof (or pursuant to a written consent if the PubCo Stockholders act by written consent in lieu of a meeting), the Stockholder shall, or shall cause the holder of record on any applicable record date to, be present (in person or by proxy) and to vote the Subject Shares (a) in favor of adopting the Merger Agreement and approving the Merger, the other Contemplated Transactions, the PubCo Stockholder Matters, and the other actions contemplated by the Merger Agreement, (b) against approval of any proposal made in opposition to, or in competition with, the Merger Agreement or the consummation of the Merger, and (c) against any Acquisition Proposal. Except as permitted under clauses (A) through (H) of Section 1.4 below, Stockholder shall retain at all times the right to vote the Subject Shares in Stockholder’s sole discretion and without any other limitation on those matters other than those set forth in this Section 1.1 that are at any time or from time to time presented for consideration to the PubCo Stockholders.
1.2. No Inconsistent Arrangements. Except as provided hereunder or under the Merger Agreement, prior to PubCo obtaining the Required PubCo Stockholder Vote, the Stockholder shall not, directly or indirectly, (a) create any Encumbrance other than restrictions imposed by Law or pursuant to this Agreement on any Subject Shares, (b) transfer, sell, assign, gift or otherwise dispose of (collectively, “Transfer”), or enter into any contract with respect to any Transfer of, the Subject Shares or any interest therein, (c) grant or permit the grant of any proxy, power of attorney or other authorization in or with respect to the Subject Shares, (d) deposit or permit the deposit of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Subject Shares, or (e) take any action that, to the knowledge of the Stockholder, would have the effect of preventing the Stockholder from performing the Stockholder’s obligations hereunder. Any action taken in violation of the 

foregoing sentence shall be null and void ab initio. Notwithstanding the foregoing, (i) the Stockholder may (A) make transfers or dispositions of the Subject Shares to any trust for the direct or indirect benefit of the Stockholder or the immediate family of the Stockholder, (B) make transfers or dispositions of the Subject Shares by will, other testamentary document or intestate succession to the legal representative, heir, beneficiary or a member of the immediate family of the Stockholder, (C) make transfers of the Subject Shares to stockholders, direct or indirect affiliates (within the meaning set forth in Rule 405 under the Securities Act), current or former partners (general or limited), members or managers of the Stockholder, as applicable, or to the estates of any such stockholders, affiliates, partners, members or managers, or to another corporation, partnership, limited liability company or other business entity that controls, is controlled by or is under common control with the Stockholder, (D) make transfers that occur by operation of law pursuant to a qualified domestic relations order or in connection with a divorce settlement, (E) make transfers or dispositions not involving a change in beneficial ownership, (F) if the Stockholder is a trust, make transfers or dispositions to any beneficiary of the Stockholder or the estate of any such beneficiary, (G) exercise an option or warrant (including a net or cashless exercise of such option or warrant) to purchase PubCo Shares, and (H) Transfer PubCo Shares to PubCo to cover tax withholding obligations of the Stockholder in connection with any option exercise or the vesting of any restricted stock or restricted stock unit award, provided that, in each case, the underlying PubCo Shares shall continue to be subject to the restrictions on transfer set forth in this Agreement. With respect to clauses (A) through (F) above, (i) the transferee agrees in writing to be bound by the terms and conditions of this Agreement and either the Stockholder or the transferee shall provide the Company with a copy of such agreement promptly upon consummation of any such Transfer, and (ii) no filing under the Exchange Act or other public announcement shall be required or shall be made voluntarily in connection with the establishment of such an agreement. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.
1.3. Documentation and Information. The Stockholder shall permit and hereby authorizes the Company and PubCo to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that the Company or PubCo reasonably determines to be necessary in connection with the Merger and any of the Contemplated Transactions, the Stockholder’s identity and ownership of the Subject Shares and the nature of the Stockholder’s commitments and obligations under this Agreement. Company and PubCo are each an intended third-party beneficiary of this Section 1.3.
1.4. Irrevocable Proxy. The Stockholder hereby revokes (or agrees to cause to be revoked) any proxies that the Stockholder has heretofore granted with respect to the Subject Shares. The Stockholder hereby irrevocably appoints the Company as attorney-in-fact and proxy for and on behalf of the Stockholder, for and in the name, place and stead of the Stockholder, to: (a) attend any and all meetings of PubCo Stockholders, (b) vote, express consent or dissent or issue instructions to the record holder to vote the Subject Shares in accordance with the provisions of Section 1.1 at any and all meetings of PubCo Stockholders or in connection with any action sought to be taken by written consent of PubCo Stockholders without a meeting and (c) grant or withhold, or issue instructions to the record holder to grant or withhold, consistent with the provisions of Section 1.1, all written consents with respect to the Subject Shares at any and all meetings of PubCo Stockholders or in connection with any action sought to be taken by written consent of PubCo Stockholders without a meeting. The Company agrees not to exercise the proxy granted herein for any purpose other than the purposes described in this Agreement. The foregoing proxy shall be deemed to be a proxy coupled with an interest, is irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of the Stockholder, as applicable) until the termination of this Agreement and shall not be terminated by operation of law or upon the occurrence of any other event other than the termination of this Agreement pursuant to Section 4.2. The Stockholder authorizes such attorney and proxy to substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the Secretary of PubCo. The Stockholder hereby affirms that the proxy set forth in this Section 1.4 is given in connection with and granted in consideration of and as an inducement to Company, PubCo and Merger Sub to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Stockholder under Section 1.1. The proxy set forth in this Section 1.4 is executed and intended to be irrevocable, subject, however, to its automatic termination upon the termination of this Agreement pursuant to Section 4.2. With respect to any Subject Shares that are owned beneficially by the Stockholder but are not held of record by the Stockholder (other than shares beneficially owned by the Stockholder that are held in the name of a bank, broker or nominee), the 
2

Stockholder shall take all action necessary to cause the record holder of such Subject Shares to grant the irrevocable proxy and take all other actions provided for in this Section 1.4 with respect to such Subject Shares.
1.5. No Ownership Interest. Nothing contained in this Agreement will be deemed to vest in the Company any direct or indirect ownership or incidents of ownership of or with respect to the Subject Shares. All rights, ownership and economic benefits of and relating to the Subject Shares will remain and belong to the Stockholder, and the Company will have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of PubCo or exercise any power or authority to direct Stockholder in the voting of any of the Subject Shares, except as otherwise expressly provided herein with respect to the Subject Shares and except as otherwise expressly provided in the Merger Agreement.

Except pursuant to the Organizational Documents of PubCo, no Person has any contractual or other right or obligation to purchase or otherwise acquire any of the Subject Shares. For purposes of this Agreement “Beneficial Ownership” shall be interpreted as defined in Rule 13d-3 under the Exchange Act; provided that for purposes of determining Beneficial Ownership, a Person shall be deemed to be the Beneficial Owner of any securities that may be acquired by such Person pursuant to any Contract or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise (irrespective of whether the right to acquire such securities is exercisable immediately or only after the passage of time, including the passage of time in excess of 60 days, the satisfaction of any conditions, the occurrence of any event or any combination of the foregoing).

The Stockholder has had an opportunity to review with its own tax advisors the tax consequences of the Merger and the Contemplated Transactions. The Stockholder understands that it must rely solely on its advisors and not on any statements or representations made by PubCo, the Company, or any of their respective agents or representatives. The Stockholder understands that such Stockholder (and not PubCo, the Company, or the Surviving Corporation) shall be responsible for such Stockholder’s tax liability that may arise as a result of the Merger or the Contemplated Transactions.

With respect to the Stockholder, as of the date hereof, there is no action, suit, investigation, or proceeding pending against, or, to the knowledge of the Stockholder, threatened in writing against, the Stockholder or any of the Stockholder’s properties or assets (including the Subject Shares) that could reasonably be expected to prevent, delay, or impair the ability of the Stockholder to perform the Stockholder’s obligations hereunder or to consummate the transactions contemplated hereby.
2.6. Non-Contravention. The execution and delivery of this Agreement by the Stockholder and the performance of the transactions contemplated by this Agreement by the Stockholder does not and will not violate, conflict with, or result in a breach of: (a) the Organizational Documents of such Stockholder, (b) any applicable Law or any injunction, judgment, order, decree, ruling, charge, or other restriction of any Governmental Authority to which the Stockholder is subject, or (c) any Contract to which the Stockholder is a party or is bound or to which the Subject Shares are subject, such that it could reasonably be expected to prevent, delay or impair the ability of the Stockholder to perform the Stockholder’s obligations hereunder or to consummate the transactions contemplated hereby.

4.4. Amendments and Waivers. Any provision of this Agreement may be amended or waived if such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement, or in the case of a waiver, by the party against whom the waiver is to be effective.

4.5. Binding Effect; Benefit; Assignment. The provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. Except as set forth in Section 1.3 and Section 4.3, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any person other than the parties hereto and their respective successors and assigns. Neither party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of the other party hereto, except that the Company may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to one or more of its Affiliates at any time; provided that such transfer or assignment shall not relieve the Company of any of its obligations hereunder.
4.6. Governing Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between any of the parties arising out of or relating to this Agreement or any of the Contemplated Transactions, each of the parties: (a) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the United States District Court for the District of Delaware or, to the extent that neither of the foregoing courts has jurisdiction, the Superior Court of the State of Delaware; (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 4.6; (c) waives any objection to laying venue in any such action or proceeding in such courts; (d) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any party hereto; (e) agrees that service of process upon such party in any such action or proceeding shall be effective if notice is given in accordance with Section 4.1 of this Agreement; and (f) irrevocably and unconditionally waives the right to trial by jury.
4.7. Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by all parties by electronic transmission in .PDF format shall be sufficient to bind the parties to the terms and conditions of this Agreement.
4.8. Entire Agreement. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof.
5

4.9. Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.
4.10. Specific Performance. Any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms (including failing to take such actions as are required of it hereunder to consummate this Agreement) or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at Law or in equity, and each of the parties waives any bond, surety or other security that might be required of any other party with respect thereto. Each of the parties further agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that any other party has an adequate remedy at Law or that any award of specific performance is not an appropriate remedy for any reason at Law or in equity.
4.11. Construction.
(a) For purposes of this Agreement, whenever the context requires: any singular term shall be deemed to include the plural, and any plural term the singular, the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include masculine and feminine gender.
(b) The parties agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement.
(c) As used in this Agreement, “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import. The word “or” is not exclusive.
(d) Except as otherwise indicated, references to any Person include the successors and permitted assigns of that Person.
(e) Except as otherwise indicated, references to any statute are to that statute and to the rules and regulations promulgated thereunder, in each case as amended, modified, re-enacted thereof, substituted, from time to time.
(f) Except as otherwise indicated, all references in this Agreement to “Sections,” “Articles,” and “Schedules” are intended to refer to Sections or Articles of this Agreement and Schedules to this Agreement, respectively.
(g) The bold-faced headings contained in this Agreement are for convenience of reference only, shall not be deemed to be a part of this Agreement and shall not be referred to in connection with the construction or interpretation of this Agreement.
6

4.12. Further Assurances. Each of the parties hereto will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary under applicable Law to perform their respective obligations as expressly set forth under this Agreement.
4.13. Capacity as Stockholder. The Stockholder signs this Agreement solely in the Stockholder’s capacity as a holder of PubCo Shares, and not in the Stockholder’s capacity as a director, officer or employee of PubCo or any of its Subsidiaries or in the Stockholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust. Notwithstanding anything herein to the contrary, nothing herein shall in any way restrict a director or officer of PubCo in the exercise of his or her fiduciary duties as a director or officer of PubCo or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust or prevent or be construed to create any obligation on the part of any director or officer of PubCo or any trustee or fiduciary of any employee benefit plan or trust from taking any action in his or her capacity as such director, officer, trustee or fiduciary.
4.14. No Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (a) the PubCo Board has approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of PubCo’s Organizational Documents and the Merger, (b) the Merger Agreement is executed by all parties thereto, and (c) this Agreement is executed by all parties hereto.

For purposes of this Lock-Up Agreement, "immediate family" shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.  The undersigned now has, and, except as contemplated by the immediately preceding sentence, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned's Shares, free and clear of all liens, encumbrances, and claims whatsoever.  The undersigned also agrees and consents to the entry of stop transfer instructions with PublicCo's transfer agent (the "Transfer Agent") and registrar against the transfer of the Undersigned's Shares except in compliance with the foregoing restrictions.
In order to enforce this covenant, PublicCo shall impose irrevocable stop-transfer instructions preventing the Transfer Agent from effecting any actions in violation of this Lock-Up Agreement.
The undersigned acknowledges that the execution, delivery and performance of this Lock-Up Agreement is a material inducement to each Buyer to complete the transactions contemplated by the Securities Purchase Agreement and that PublicCo shall be entitled to specific performance of the undersigned's obligations hereunder. The undersigned hereby represents that the undersigned has the power and authority to execute, deliver and perform this Lock-Up Agreement, that the undersigned has received adequate consideration therefor and that the undersigned will indirectly benefit from the closing of the transactions contemplated by the Securities Purchase Agreement.  
The undersigned understands and agrees that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned's heirs, legal representatives, successors, and assigns.
This Lock-Up Agreement may be executed in two counterparts, each of which shall be deemed an original but both of which shall be considered one and the same instrument.
This Lock-Up Agreement may not be amended, modified, waived or terminated before the end of the Restricted Period.
In the event the Securities Purchase Agreement is terminated pursuant to Section 9 thereof, this Lock-Up Agreement shall automatically be terminated and become void and of no further force or effect.
This Lock-Up Agreement will be governed by and construed in accordance with the laws of the State of New York, without giving effect to any choice of law or conflicting provision or rule (whether of the State of New York, or any other jurisdiction) that would cause the laws of any jurisdiction other than the State of New York to be applied.  In furtherance of the foregoing, the internal laws of the State of New York will control the interpretation and construction of this Lock-Up Agreement, even if under such jurisdiction's choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.
