Execution Version

NON-REDEMPTION AGREEMENT

This NON-REDEMPTION AGREEMENT (this “Agreement”), dated as of August 28, 2023, is made by and among First Light Acquisition Group, Inc., a Delaware corporation (the “Company”), and the Backstop Investor (as defined below).

WHEREAS, the Company is a special purpose acquisition company whose Class A Common Stock (“Common Stock”) is traded on the NYSE American stock exchange under the symbol “FLAG”, and whose warrants (“Warrants”) are traded on the NYSE American stock exchange under the symbol “FLAG/WS”, among other securities of the Company;

WHEREAS, the Company, First Light Acquisition Group, LLC (the “Sponsor”), FLAG Merger Sub, Inc., Allan Camaisa, Calidi Biotherapeutics, Inc. (“Calidi”) have entered into an Agreement and Plan of Merger, dated as of January 9, 2023, which was subsequently amended on February 9, 2023 and April 12, 2023 (as may be further amended from time to time, the “Transaction Agreement”);

WHEREAS, the Company and Backstop Investor on behalf of certain funds, investors, entities or accounts that are managed, sponsored or advised by Backstop Investor or its affiliates (the “Backstop Investor”) are entering into this Agreement in anticipation of the closing of the business combination contemplated by the Transaction Agreement (the “Business Combination”);

WHEREAS, the Transaction Agreement includes the condition that the Company shall have at least $15,000,000 prior to or at the Closing (as defined below), net of any amounts required to be paid to satisfy the redemption of any shares of Common Stock in connection with the Business Combination, with certain adjustments related to expenses and indebtedness (the “Minimum Cash Condition”), at the consummation of the Business Combination (the “Closing”);

WHEREAS, prior to or concurrent with the execution of this Agreement, the Company may enter into other non-redemption agreements with substantially similar terms with other stockholders of the Company (such non-redemption agreements, “Other Non-Redemption Agreements”, and such other stockholders of the Company, “Other Backstop Investors”), which, together with this Agreement, mandate the non-redemption of no more than approximately 380,952 shares of Common Stock;

WHEREAS, as of the date hereof in respect of the Common Stock, the Backstop Investor has voting and investment power over the number of shares of Common Stock set out in Exhibit A (the “Backstop Investor Shares”), which number shall be equal to 2.0 times the number of Committed Shares (as defined below). For the avoidance of doubt, the Backstop Investor may have voting and investment power over additional shares of Common Stock (such shares, “Non-Backstop Investor Shares”) which will not be subject to this Agreement;

WHEREAS, pursuant to the Company’s Amended and Restated Certificate of Incorporation (the “COI”), in its capacity as a holder of Common Stock, the Backstop Investor has the right to require that the Company redeem the Backstop Investor Shares held by the Backstop Investor in connection with the Business Combination, for the Redemption Price (as defined in the COI), representing the right to receive the Backstop Investor’s portion of the funds currently in the Company’s trust account, to the extent the Backstop Investor exercises such redemption right;

WHEREAS, the Company has filed a definitive merger proxy with a deadline to exercise the redemption rights of shares of Common Stock of 5:00 p.m., Eastern Daylight time on August 18, 2023 (the “Redemption Deadline”), which was two (2) business days before the originally scheduled special meeting (the “Meeting”) of stockholders of the Company to approve the Business Combination, and which was held on August 28, 2023;

WHEREAS, pursuant to the terms of this Agreement, the Backstop Investor desires to agree to refrain from exercising such redemption right with respect to the Backstop Investor Shares; and

WHEREAS, all capitalized terms used but not defined herein shall have the respective meanings specified in the Transaction Agreement.

NOW, THEREFORE, in consideration of the mutual agreements set forth herein, the parties agree as follows:

1.    Non-Redemption Agreement. Subject to the conditions set forth in this Agreement, the Backstop Investor irrevocably and unconditionally hereby agrees that it will not elect to redeem or otherwise tender or submit for redemption any of the Backstop Investor Shares in connection with the Business Combination; provided, however, that in the event the Backstop Investor has previously elected to redeem, tendered or submitted the Backstop Investor Shares for redemption, the Backstop Investor shall rescind or reverse such redemption within 2 business days following the execution of this Agreement and no later than 2 Business Days prior to the closing of the Business Combination.

2.    Non-Redemption Payment. Immediately upon consummation of the Business Combination, the Company shall pay to the Backstop Investor a payment in respect of its Backstop Investor Shares (the “Non-Redemption Cash”) in cash released from the Trust Account (as defined below) equal to the number of Backstop Investor Shares multiplied by the Redemption Price, minus 64,762 of the Backstop Investor Shares (the “Committed Shares”) multiplied by the Redemption Price.

3.    Restrictions. From the date of this Agreement until such time as the Backstop Investor has irrevocably rescinded or reversed the redemption right with respect to the Backstop Investor Shares, the Backstop Investor hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any understanding with it, will offer for sale, sell or otherwise dispose of (including by gift, merger, tendering into any tender offer or exchange offer or otherwise) any Backstop Investor Shares (collectively, a “Transfer”).

4.    Representations and Warranties. Each of the parties hereto represents and warrants to the other party that: (a) it is a validly existing company, partnership or corporation, in good standing under the laws of the jurisdiction of its formation or incorporation; (b) this Agreement constitutes a valid and legally binding obligation on it in accordance with its terms, subject to laws relating to bankruptcy, insolvency and relief of debtors, and laws governing specific performance, injunctive relief and other equitable remedies; (c) the execution, delivery and performance of this Agreement by it has been duly authorized by all necessary corporate action, and (d) the execution,

2

delivery and performance of this Agreement will not result in a violation of its Certificate of Formation or Certificate of Incorporation, as applicable, or conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement or instrument to which it is a party or by which it is bound. The Backstop Investor represents and warrants to the Company, that, as of the date hereof, (i) the Backstop Investor beneficially owns the number of shares of Common Stock set forth opposite the Backstop Investor’s name on Exhibit A hereto and (ii) all such shares of Common Stock are otherwise currently entitled to be redeemed.

5.    Additional Covenants. The Backstop Investor hereby covenants and agrees that, except for this Agreement, the Backstop Investor shall not, at any time while this Agreement remains in effect, (i) enter into any voting agreement or voting trust with respect to the Backstop Investor Shares (or any securities received in exchange therefore) inconsistent with Backstop Investor’s obligations pursuant to this Agreement, (ii) grant a proxy, a consent or power of attorney with respect to the Backstop Investor Shares (or any securities received in exchange therefore), (iii) enter into any agreement or take any action that would make any representation or warranty of Backstop Investor contained herein untrue or inaccurate in any material respect or have the effect of preventing or disabling Backstop Investor from performing any of its obligations under this Agreement, or (iv) purchase the Backstop Investor Shares at a price higher than the price offered through the Company’s redemption process. For the avoidance of doubt, in no event shall the Backstop Investor claim in respect of the Backstop Investor Shares any entitlement to shares of Common Stock otherwise to be issued to holders of Common Stock who did not redeem their shares (the “Non-Redeeming Continuation Shares”) at closing of the Business Combination. The Backstop Investor will suppress or reject any attempt to issue Non-Redeeming Continuation Shares in respect of the Backstop Investor Shares and if issued to such Backstop Investor will promptly return to the Company such Non-Redeeming Continuation Shares.

6.    Expenses. Each party shall be responsible for its own fees and expenses related to this Agreement and the transactions contemplated hereby.

7.    Termination. This Agreement and all of its provisions shall terminate and be of no further force or effect upon the earliest to occur of (a) the termination of the Transaction Agreement in accordance with its terms, (b) the mutual written consent of the parties hereto, (c) September 15, 2023, if the Business Combination has not been consummated by such date, and (d) the payment of the Cash Fee to the Backstop Investor following the consummation of the Business Combination. Upon such termination of this Agreement, all obligations of the parties under this Agreement will terminate, without any liability or other obligation on the part of any party hereto to any person in respect hereof or the transactions contemplated hereby; provided that, notwithstanding the foregoing or anything to the contrary in this Agreement, the termination of this Agreement pursuant to clauses (a) and (d) above shall not affect any liability on the part of any party for an intentional breach of this Agreement. Section 6 through and including Section 27 of this Agreement will survive the termination of this Agreement.

8.    Trust Account Waiver. The Backstop Investor acknowledges that the Company has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (“IPO”) and certain proceeds of a private placement (including interest accrued from time to time thereon) for the benefit of its public stockholders and certain other parties (including the underwriters of the IPO). For good and valuable consideration, the receipt and sufficiency of

3

which are hereby acknowledged, the Backstop Investor hereby agrees (on its own behalf and on behalf of its related parties) that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and it shall not make any claim against the Trust Account, regardless of whether such claim arises as a result of, in connection with or relating in any way to this Agreement or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”); provided, that the Released Claims shall not include any rights or claims of the Backstop Investor or any of its related parties as a shareholder of the Company to the extent related to or arising from any Backstop Investor Shares. The Backstop Investor hereby irrevocably waives (on its own behalf and on behalf of its related parties) any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, this Agreement and will not seek recourse against the Trust Account with respect to the Released Claims. For the avoidance of doubt, this provision shall not restrict the Backstop Investor’s Redemption Rights (as defined in the COI) with respect to the Non-Backstop Investor Shares.

9.    Public Disclosure. The Company shall file a Current Report on Form 8-K with the SEC (the “Current Report”) reporting the material terms of this Agreement but not including the names of the Backstop Investor and its affiliates and/or advised funds, unless required by law, within four (4) Business Days following the execution of this Agreement. The Company shall not, and shall cause its representatives to not, disclose any material non-public information to the Backstop Investor concerning the Company, the Common Stock or the Business Combination, other than the existence of this Agreement, such that the Backstop Investor shall not be in possession of any such material non-public information from and after the filing of the Current Report. Notwithstanding anything in this Agreement to the contrary, the Backstop Investor agrees that the Company shall have the right to publicly disclose the nature of the Backstop Investor’s commitments, arrangements and understandings under and relating to this Agreement in any filing by the Company with the SEC.

10.    Governing Law. This Agreement, the rights and duties of the parties hereto, and any disputes (whether in contract, tort or statute) arising out of, under or in connection with this Agreement will be governed by and construed and enforced in accordance with the laws of the State of Delaware, without giving effect to its principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of the laws of another jurisdiction. The parties irrevocably and unconditionally submit to the exclusive jurisdiction of the United States District Court for the District of Delaware or, if such court does not have jurisdiction, the Delaware state courts located in Wilmington, Delaware, in any action arising out of or relating to this Agreement. The parties irrevocably agree that all such claims shall be heard and determined in such a Delaware federal or state court, and that such jurisdiction of such courts with respect thereto will be exclusive. Each party hereby waives, and agrees not to assert, as a defense in any action, suit or proceeding arising out of or relating to this Agreement that it is not subject to such jurisdiction, or that such action, suit or proceeding may not be brought or is not maintainable in such courts or that the venue thereof may not be appropriate or that this Agreement may not be enforced in or by such courts. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of any such dispute and agree that mailing of process or other papers in connection with any such action, suit or proceeding in the manner provided in Section 24 hereof or in such other manner as may be permitted by law, will be valid and sufficient service thereof.

11.    Waiver of Jury Trial. To the extent not prohibited by applicable law that cannot be waived, each of the parties hereto irrevocably waives any right it may have to trial by jury in respect of any litigation based on, arising out of, under or in connection with this Agreement or any course of conduct, course of dealing, verbal or written statement or action of any party hereto or thereto, in each case, whether now existing or hereafter arising, and whether in contract, tort, statute, equity or otherwise. Each party hereby further agrees and consents that any such litigation shall be decided by court trial without a jury and that the parties to this Agreement may file a copy of this Agreement with any court as written evidence of the consent of the parties to the waiver of their right to trial by jury.

12.    Freely Tradable. The Company confirms that (i) the Backstop Investor Shares will be freely tradeable without restrictive legends following the Business Combination; the Backstop Investor Shares will not require re-registration pursuant to a registration statement filed with the SEC on Form S-1 or Form S-3 or equivalent following the Business Combination; and that the Backstop Investor shall not be identified as a statutory underwriter in any registration statement filed with the SEC on Form S-1 or Form S-3 or equivalent.

13.    Form W-9 or W-8. The Backstop Investor shall, upon or prior to the consummation of the Business Combination, execute and deliver to the Company a completed IRS Form W-9 or Form W-8, as applicable.

14.    Withholding. Notwithstanding any other provision of this Agreement, the Company and any of its agents and representatives, as applicable, shall be entitled to deduct and withhold from any amount payable hereunder any such taxes as may be required to be deducted and withheld from such amounts (and any other amounts treated as paid for applicable tax law) under the Internal Revenue Code of 1986, as amended, or any other applicable tax law (as determined in good faith by the party so deducting or withholding in its sole discretion). To the extent that any amounts are so deducted and withheld, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

15.    Non-Reliance. The Backstop Investor has had the opportunity to consult its own advisors, including financial and tax advisors, regarding this Agreement or the arrangements contemplated hereunder and the Backstop Investor hereby acknowledges that neither the Company nor any representative or affiliate of the Company has provided or will provide the Backstop Investor with any financial, tax or other advice relating to this Agreement or the arrangements contemplated hereunder.

16.    No Third Party Beneficiaries. This Agreement shall be for the sole benefit of the parties, Calidi and their respective successors and permitted assigns. Except as expressly named in this Section 16, this Agreement is not intended, nor shall be construed, to give any Person, other than the parties, Calidi and their respective successors and assigns, any legal or equitable right, benefit or remedy of any nature whatsoever by reason this Agreement.

17.    Assignment. This Agreement and all of the provisions hereof will be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder will be assigned (including by operation of law) without the prior written consent of the non-assigning party hereto (not to be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing, the

5

Backstop Investor may transfer its rights, interests and obligations hereunder to one or more investment funds or accounts managed or advised by the Backstop Investor (or a related party or affiliate) and to the extent such transferee is not a party to this Agreement, such transferee shall agree to be bound by the terms hereof prior to any such transfer being effectuated.

18.    Specific Performance. The parties agree that irreparable damage may occur in the event that any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached. It is accordingly agreed that monetary damages may not be an adequate remedy for such breach and the non-breaching party shall be entitled to seek injunctive relief, in addition to any other remedy that such party may have in law or in equity, and to enforce specifically the terms and provisions of this Agreement in the chancery court or any other state or federal court within the State of Delaware.

19.    Amendment. This Agreement may not be amended, changed, supplemented, waived or otherwise modified, except upon the execution and delivery of a written agreement executed by the parties hereto.

20.    Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

21.    No Partnership, Agency or Joint Venture. This Agreement is intended to create a contractual relationship between the Backstop Investor, on the one hand, and the Company, on the other hand, and is not intended to create, and does not create, any agency, partnership, joint venture or any like relationship between the parties.

22.    Blocker Provision. Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by the Backstop Investor upon any exercise of Warrants in the Company and its successor(s) shall be limited to the extent necessary to ensure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Backstop Investor and its affiliates and any other persons whose beneficial ownership of Common Stock would be aggregated with the Backstop Investor’s for purposes of Section 13(d) of the Exchange Act, does not exceed 9.99% of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Each delivery of a Notice of Exercise hereunder will constitute a representation by the Backstop Investor that it has evaluated the limitation set forth in this paragraph and determined that issuance of the full number of Warrant Shares requested in such Notice of Exercise is permitted under this paragraph. This provision shall not restrict the number of shares of Common Stock which a Backstop Investor may receive or beneficially own in order to determine the amount of securities or other consideration that such Backstop Investor may receive in the event of a merger or other business combination or reclassification involving the Company. For the avoidance of doubt, this restriction shall not be conferred upon any third party to whom the Backstop Investor transfers such Warrants. This restriction may not be waived.

24.    Counterparts. This Agreement may be executed in two or more counterparts (any of which may be delivered by electronic transmission), each of which shall constitute an original, and all of which taken together shall constitute one and the same instrument, and shall include images of manually executed signatures transmitted by electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law.

25.    Entire Agreement. This Agreement and the agreements referenced herein constitute the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersede all prior understandings, agreements or representations by or among the parties hereto to the extent that they relate in any way to the subject matter hereof.

26.    Most Favored Nation. In the event the Company or the Sponsor enters one or more other similar non-redemption agreements with any Other Backstop Investors before or after the execution of this Agreement in connection with the Meeting, the Company represents that the terms of such other similar non-redemption agreements are not materially more favorable to such Other Backstop Investors thereunder than the terms of this Agreement are in respect of the Backstop Investor. In the event that any Other Backstop Investor is afforded any such more favorable terms pursuant to such similar non-redemption agreement than the Backstop Investor, the Company shall promptly inform the Backstop Investor of such more favorable terms in writing, and the Backstop Investor shall have the right to elect to have such more favorable terms included herein, in which case the parties hereto shall promptly amend this Agreement to effect the same.

27.    Structuring Consideration. In consideration for the Backstop Investor structuring the Agreement and transactions described herein, immediately upon consummation of the Business Combination, the Company shall award the Backstop Investor200,000 shares of Common Stock as structuring shares (the “Structuring Shares”), which obligation to deliver Structuring Shares, at the option of the Backstop Investor, can be satisfied by the Backstop Investor rescinding or reversing from redemption prior to the Closing, 200,000 shares of Common Stock that the backstop Investor owns that otherwise would have been redeemed and are not included as Backstop Investor Shares under this Agreement or as Recycled Shares as such term is defined in the Forward Purchase Agreement being entered into by the parties concurrently to this Agreement, but will instead be considered as Structuring Shares, in which case, on the day of the Closing, the

8

Company will pay to the Backstop Investor an amount equal to the Redemption Price multiplied by such 200,000 shares for which the Backstop Investor has reversed or rescinded the redemption for purposes of being considered Structuring Shares. In the absence of such alternative, the Backstop Investor acknowledges that any Structuring Shares issued will be “restricted securities” under the Securities Act of 1933, as amended (the “Securities Act”)), and will be issued subject to the same representations and transfer restrictions applicable to the Subscriber and Subscribed Shares (each, as defined in the Subscription Agreement being entered into by the parties concurrently to this Agreement) as set forth in such Suscription Agreement. Such Structuring Shares shall also be entitled to the same registration rights applicable to Subscribed Shares as set forth in Section 5 of such Subscription Agreement. The Structuring Shares shall serve to increase the number of shares held by the Backstop Investor (but not the Backstop Investor Shares) without increasing the Committed Shares. Furthermore, for a period of twelve (12) months following the date of this Agreement, in the event the Company seeks any equity, derivatives, debt-linked security investment or debt offerings (the “Future Financings”), the Company acknowledges and agrees that it shall first offer the Backstop Investor the ability to participate in at least 30% of any such Future Financings prior to the execution of any such agreements.
