GUARANTY

1. Indebtedness Guaranteed. Each Guarantor hereby absolutely and unconditionally guarantees the prompt payment in full of the Obligations (as defined below), as and when the same (including without limitation portions thereof) become due and payable. Each Guarantor acknowledges that the amount of the Obligations may exceed the principal amount of the Notes. Each Guarantor further acknowledges that the foregoing guarantee is made for the timely payment and performance of each of the Obligations and is not merely a guaranty of collection. For purposes of this Guaranty, “Obligations” means (a) all loans, advances, debts, liabilities and obligations, arising on or after the date of this Guaranty, owed by Company or Guarantors to Investor, pursuant to the Notes, the Purchase Agreement, or any other Transaction Documents, including any modification or amendment to any of the foregoing, and (b) all costs and expenses, including reasonable attorneys’ fees incurred in connection with enforcement or collection actions incurred by Investor in connection with the Notes or in connection with the collection or enforcement of any portion of the Obligations.

2. DACA. The Obligations shall be secured by a Deposit Account Control Agreement of even date herewith among FFAI Holdings, Lakeside Bank (the “Bank”), and Investor (the “DACA”), the Deposit Account (as defined in the DACA), and the funds held therein pursuant to the DACA.

Upon sending a Lender Instruction Notice, Investor will have the right without further notice or demand, to apply all or any portion of the funds held in the Deposit Account to the Obligations.

3. Representations and Warranties. Each Guarantor hereby represents and warrants to Investor that:

(d) The execution, delivery and performance of this Guaranty will not (i) violate any provision of any law, statute, rule or regulation or any order, writ, judgment, injunction, decree, determination or award of any court, governmental agency or arbitrator presently in effect having applicability to Guarantor, (ii) violate or contravene any provision of Guarantor’s organizational documents, or (iii) result in a breach of or constitute a default under any indenture, loan or credit agreement or any other material agreement, lease or instrument to which Guarantor is a party or by which it or any of its properties may be bound or result in the creation of any lien thereunder. Guarantor is not in default under or in violation of any such law, statute, rule or regulation, order, writ, judgment, injunction, decree, determination or award or any such indenture, loan or credit agreement or other agreement, lease or instrument in any case in which the consequences of such default or violation could have a material adverse effect on its business, operations, properties, assets or condition (financial or otherwise).

(e) No order, consent, approval, license, authorization or validation of, or filing, recording or registration with, or exemption by, any governmental or public body or authority is required on Guarantor’s part to authorize, or is required in connection with the execution, delivery and performance of, or the legality, validity, binding effect or enforceability of, this Guaranty.

(f) There are no actions, suits or proceedings pending or, to Guarantor’s knowledge, threatened against or affecting Guarantor or any of its properties before any court or arbitrator, or any governmental department, board, agency or other instrumentality which, if determined adversely to Guarantor, would have a material adverse effect on its business, operations, property or condition (financial or otherwise) or on its ability to perform its obligations hereunder.

(h) Guarantor has examined or has had the full opportunity to examine the A-1 Note and the B Note and all the other Transaction Documents, all the terms of which are acceptable to Guarantor.

(i) This Guaranty is given in consideration of Investor entering into the A-1 Note and the B Note and providing financing thereunder.

(j) Guarantor has received adequate consideration and at least a reasonably equivalent value in exchange for the giving of this Guaranty, which Guarantor hereby acknowledges having received, and thereby will materially benefit from the financial accommodations granted to Company by Investor pursuant to the Notes. Investor may rely conclusively on the continuing warranty, hereby made, that Guarantor continues to be benefitted by Investor’s extension of credit accommodations to Company and Investor shall have no duty to inquire into or confirm the receipt of any such benefits, and this Guaranty shall be effective and enforceable by Investor without regard to the receipt, nature or value of any such benefits. As such, this Guaranty is a valid and binding obligation of Guarantor. Guarantor further covenants and agrees that it will not use lack of consideration as a defense to its performance of its obligations under this Guaranty.

No exercise or non-exercise by Investor of any right available to Investor, no dealing by Investor with Guarantors or any other guarantor, endorser of the Notes or any other person, and no change, impairment or release of all or a portion of the obligations of Company under any of the Transaction Documents or suspension of any right or remedy of Investor against any person, including, without limitation, Company and any other such guarantor, endorser or other person, shall in any way affect any of the obligations of Guarantors hereunder or any security furnished by Guarantors or give Guarantors any recourse against Investor. Guarantors acknowledges that its obligations hereunder are independent of the obligations of Company.

5. Waiver. To the extent permitted by law, each Guarantor hereby waives and relinquishes all rights and remedies accorded by applicable law to guarantors and agrees not to assert or take advantage of any such rights or remedies, including (without limitation) (a) any right to require Investor to proceed against Company or any other person or to pursue any other remedy in Investor’s power before proceeding against Guarantor; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other person or persons or the failure of Investor to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other person or persons; (c) demand, protest and notice of any kind, including, without limitation, notice of the existence, creation or incurring of any new or additional indebtedness, liability or obligation or of any action or non-action on the part of Company, Investor, any endorser or creditor of Company or Guarantor or on the part of any other person whomsoever under this or any other instrument in connection with any obligation or liability or evidence of indebtedness held by Investor as collateral or in connection with any Obligation hereby guaranteed; (d) any defense based upon an election of remedies by Investor which may destroy or otherwise impair the subrogation rights of Guarantor or the right of Guarantor to proceed against Company for reimbursement, or both; (e) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (f) any duty on the part of Investor to disclose to Guarantor any facts Investor may now or hereafter know about Company, regardless of whether Investor has reason to believe that any such facts materially increase the risk beyond that which Guarantor intends to assume or has reason to believe that such facts are unknown to Guarantor or has a reasonable opportunity to communicate such facts to Guarantor, since Guarantor acknowledges that it is fully responsible for being and keeping informed of the financial condition of Company and of all circumstances bearing on the risk of non-payment of any Obligation; (g) any defense arising because of Investor’s election, in any proceeding instituted under the Federal Bankruptcy Code, of the application of Section 1111(b)(2) of the Federal Bankruptcy Code; (h) any defense based on any borrowing or grant of a security interest under Section 364 of the Federal Bankruptcy Code; (i) any claim, right or remedy which Guarantor may now have or hereafter acquire against Company that arises hereunder and/or from the performance by Guarantor hereunder, including, without limitation, any claim, right or remedy of Investor against Company or any security which Investor now has or hereafter acquires, whether or not such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise; and (j) any obligation of Investor to pursue any other guarantor or any other person, or to foreclose on any collateral.

6. Bankruptcy. So long as any Obligation shall be owing to Investor, Guarantors shall not, without the prior written consent of Investor, commence or join with any other person in commencing any bankruptcy, reorganization, or insolvency proceeding against Company. The obligations of Guarantors under this Guaranty shall not be altered, limited or affected by any proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of Company, or by any defense which Company may have by reason of any order, decree or decision of any court or administrative body resulting from any such proceeding.

7. Claims in Bankruptcy. Guarantors shall file in any bankruptcy or other proceeding in which the filing of claims is required or permitted by law all claims that Guarantors may have against Company relating to any indebtedness, liability or obligation of Company owed to Guarantors and will assign to Investor all rights of Guarantors thereunder. If Guarantors do not file any such claim, Investor, as attorney-in-fact for Guarantors, is hereby authorized to do so in the name of Guarantors or, in Investor’s discretion, to assign the claim to a nominee and to cause proof of claim to be filed in the name of Investor’s nominee. The foregoing power of attorney is coupled with an interest and cannot be revoked. Investor or Investor’s nominee shall have the sole right to accept or reject any plan proposed in such proceeding and to take any other action that a party filing a claim is entitled to do. In all such cases, whether in administration, bankruptcy or otherwise, the person or persons authorized to pay such claim shall pay to Investor the amount payable on such claim and, to the full extent necessary for that purpose, Each Guarantor hereby assigns to Investor all of Guarantor’s rights to any such payments or distributions to which Guarantor would otherwise be entitled; provided, however, that Guarantor’s obligations hereunder shall not be deemed satisfied except to the extent that Investor receives cash by reason of any such payment or distribution. If Investor receives anything hereunder other than cash, the same shall be held as collateral for amounts due under this Guaranty. If at any time the holder of any of the Notes is required to refund to Company any payments made by Company under the Notes because such payments have been held by a bankruptcy court having jurisdiction over Company to constitute a preference under any bankruptcy, insolvency or similar law then in effect, or for any other reason, then in addition to Guarantor’s other obligation under this Guaranty, Guarantor shall reimburse the holder in the aggregate amount of such refund payments.

8. Costs and Attorneys’ Fees. If Company or any Guarantor fails to pay all or any portion of any Obligation, or any Guarantor otherwise breaches any provision hereof or otherwise defaults hereunder, Guarantors shall pay reasonable attorneys’ fees incurred by Investor in connection with the enforcement of any obligations of Guarantors hereunder, including, without limitation, any attorneys’ fees incurred in any negotiation, alternative dispute resolution proceeding subsequently agreed to by the parties, if any, litigation, or bankruptcy proceeding or any appeals from any of such proceedings.

9. Cumulative Rights. The amount of Guarantors’ liability and all rights, powers and remedies of Investor hereunder and under any other agreement now or at any time hereafter in force between Investor and Guarantors, including, without limitation, any other guaranty executed by Guarantors relating to any indebtedness, liability or obligation of Company owed to Investor, shall be cumulative and not alternative and such rights, powers and remedies shall be in addition to all rights, powers and remedies given to Investor by law. This Guaranty is in addition to and exclusive of the guaranty of any other guarantor of any indebtedness, liability or obligation of Company owed to Investor.

10. Independent Obligations. The obligations of Guarantors hereunder are independent of the obligations of Company and, to the extent permitted by law, in the event of any breach or default hereunder, a separate action or actions may be brought and prosecuted against any Guarantor whether or not Company or the other Guarantors are joined therein or a separate action or actions are brought against Company, and Investor shall have no obligation to separately pursue an action against Company with respect to the Obligations. Investor may maintain successive actions for other breaches or defaults. Investor’s rights hereunder shall not be exhausted by Investor’s exercise of any of Investor’s rights or remedies or by any such action or by any number of successive actions until and unless all Obligations have been paid and fully performed.

11. Severability. If any part of this Guaranty is construed to be in violation of any law, such part shall be modified to achieve the objective of the parties to the fullest extent permitted and the balance of this Guaranty shall remain in full force and effect.

12. Successors and Assigns. This Guaranty shall inure to the benefit of Investor, Investor’s successors and assigns, including the assignees of any Obligation, and shall bind the heirs, executors, administrators, personal representatives, successors and assigns of Guarantors. This Guaranty may be assigned by Investor with respect to all or any portion of the Obligations, and when so assigned, Guarantors shall be liable to the assignees under this Guaranty without in any manner affecting the liability of Guarantors hereunder with respect to any Obligations retained by Investor.

13. Notices. Whenever Guarantors or Investor shall desire to give or serve any notice, demand, request or other communication with respect to this Guaranty, each such notice shall be given in writing (unless otherwise specified herein) and shall be deemed effectively given on the earliest of:

14. Application of Payments or Recoveries. With or without notice to Guarantors, Investor, in Investor’s sole discretion and at any time and from time to time and in such manner and upon such terms as Investor deems fit, may (a) apply any or all payments or recoveries from Company or from any other guarantor or endorser under any other instrument or realized from any security, in such manner and order of priority as Investor may determine, to any indebtedness, liability or obligation of Company owed to Investor, whether or not such indebtedness, liability or obligation is guaranteed hereby or is otherwise secured or is due at the time of such application; and (b) refund to Company any payment received by Investor in connection with any Obligation and payment of the amount refunded shall be fully guaranteed hereby.

15. Setoff. Investor shall have a right of setoff against the Deposit Account. Such right is in addition to any right of setoff Investor may have by law. All rights of setoff may be exercised without notice or demand to Guarantors.
