Ladies and Gentlemen:

Reference is hereby made to (a) that certain Agreement and Plan of Merger, dated as of December 13, 2021, by and among Gores Holdings VIII, Inc., a Delaware corporation (the “Company”), Footprint International Holdco, Inc., a Delaware corporation (“Footprint”), Frontier Merger Sub, Inc., a Delaware corporation, and Frontier Merger Sub II, LLC, a Delaware limited liability company (as amended, modified, supplemented or waived from time to time in accordance with its terms, the “Merger Agreement”) and (b) that certain Backstop Agreement, dated as of September 5, 2022, by and among the Company, Footprint and 222 Investments, LLC, a Delaware limited liability company (“222 Investments”) (as amended, modified, supplemented or waived from time to time in accordance with its terms, the “Backstop Agreement”). In connection with the Merger Agreement, Gores Sponsor VIII LLC, a Delaware limited liability company (“Sponsor”), has committed up to $54,600,000 (as such amount may be reduced in accordance with Section 1 hereof, the “Aggregate Commitment”) to subscribe for shares of Class A Convertible Preferred Stock of the Company (the “Class A Preferred Stock”), with the same rights, preferences and privileges set forth in the certificate of designations attached to the Backstop Agreement as Exhibit A, subject to the terms and conditions of this letter agreement and the Sponsor Backstop Agreement (as defined below). Capitalized terms used but not otherwise defined herein shall have the respective meanings given to them in the Merger Agreement.

1.    Commitment.

a.    Subject to the terms and conditions hereof and the Sponsor Backstop Agreement, Sponsor hereby irrevocably commits and agrees to acquire shares of Class A Preferred Stock, at a purchase price of $10.00 per share of Class A Preferred Stock, for an aggregate purchase price in cash not to exceed the Aggregate Commitment. Sponsor shall not, under any circumstances, be obligated to purchase any shares of Class A Preferred Stock for an aggregate purchase price in excess of the Aggregate Commitment. Sponsor may effect the purchase of the Class A Preferred Stock directly or indirectly through one or more affiliated entities or other co-investors designated by it; provided, however, that no such action will reduce the amount of the Aggregate Commitment or otherwise affect the obligations of Sponsor under this letter agreement, except to the extent actually funded by such affiliated entity or co-investor (in which case Sponsor’s Aggregate Commitment will be reduced by the amount so funded). Sponsor shall not be obligated to fund the Aggregate Commitment except upon the concurrent consummation of the Closing.

b.    The Aggregate Commitment shall, without any action by any of the parties hereto, be reduced dollar for dollar by (i) the aggregate amount of cash proceeds received by the Company after the date hereof pursuant to the Note Purchase Agreement, (ii) any additional subscriptions to purchase Parent Class A Stock substantially similar to the Subscription Agreements in excess of $90,900,000 (the “Additional PIPE Investments”) and (iii) the aggregate amount of Additional Equity Commitments. For purposes of this letter agreement, “Additional Equity Commitments” means any commitment to purchase

equity securities of the Company or Footprint made on or after the date hereof and prior to the Closing Date, including pursuant to the Backstop Agreement or any agreement in substantially the same form as the Backstop Agreement, but excluding (A) the Aggregate Commitment, (B) the commitment by 222 Investments to purchase up to $250,000,000 of Class A Preferred Stock pursuant to the Backstop Agreement (as of the date hereof) and (C) $75,000,000 in respect of the agreement with KSP Footprint Investments, LLC or its Affiliates to purchase preferred stock of Footprint.

2.    Backstop Notice. On or before the second Business Day prior to the Closing Date, Footprint shall (with the Company’s collaboration) deliver a written notice (with a copy to the Company) (the “Backstop Notice”) to the Purchaser, which shall include:

a.     a certification by the Company and Footprint of the difference of (i) $685,000,000, minus (ii) $250,000,000 from the sale and issuance of Company Preferred Stock, minus (iii) the amount to be delivered to Parent at or prior to the Closing in connection with the consummation of the PIPE Investment and the Additional PIPE Investments, if any, minus (iv) the aggregate amount of cash proceeds received by Footprint pursuant to the Note Purchase Agreement, minus (v) $250,000,000 with respect to the commitment by 222 Investments pursuant to the Backstop Agreement, minus (vi) the aggregate amount of Additional Equity Commitments, minus (vii) the amount of funds contained in the Trust Account, as reduced by an amount equal to (A) the number of shares of Parent Class A Stock redeemed pursuant to the Offer, multiplied by (B) $10.00 (such difference, the “Backstop Amount”);

b.    the number of shares of Class A Preferred Stock that Sponsor shall be required to purchase, if any, and the aggregate purchase price of such shares, which amount, for the avoidance of doubt, shall in no event exceed the lesser of (i) the Backstop Amount and (ii) the Aggregate Commitment (as may be reduced in accordance with Section 1 hereof);

c.    the Company’s wire instructions; and

d.    the anticipated Closing Date.

3.    Backstop Agreement. Upon receipt of the Backstop Notice and, in the event that Sponsor is required to purchase shares of Class A Preferred Stock pursuant to the terms hereof, Sponsor (or its affiliated entities or co-investors), the Company and Footprint shall, as promptly as practicable following receipt of the Backstop Notice, enter into a backstop agreement on substantially similar terms as the Backstop Agreement or, as applicable, Sponsor shall deliver a counterpart signature page to the Backstop Agreement.

4.    Conditions Precedent. Sponsor’s obligations to fund the Aggregate Commitment (or, if less than the Aggregate Commitment, the Backstop Amount) shall be conditioned upon:

a.    the valid execution and delivery of the Backstop Agreement by all the parties thereto (other than Sponsor); and

b.     the satisfaction or waiver of all conditions precedent to the Closing set forth in Section 6 of the Backstop Agreement (except those conditions that by their nature cannot be satisfied except by actions to be taken at the Closing, provided that such conditions are actually satisfied or validly waived, to the extent permitted, at the Closing).

8.    No Assignment. The Aggregate Commitment evidenced by this letter agreement shall not be assignable by the Company or Footprint without the prior written consent of Sponsor and such consent, if granted, shall not constitute a waiver of this requirement as to any subsequent assignment; provided, that the Aggregate Commitment (or a portion thereof) evidenced by this letter agreement shall be assignable by Sponsor; provided further, that such an assignment by Sponsor shall not relieve Sponsor of its obligations under this letter agreement except by any amounts actually contributed to the Company by payment in cash by such assignees on or before the Closing, as contemplated in Section 1 above, and Sponsor shall remain liable in full for any unsatisfied portion of its obligations under this letter agreement.

9.    Amendment.

10.    Entire Agreement. This letter agreement (together with the Backstop Agreement to be entered into by the parties hereto) constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof, including any commitment letter entered into relating to the subject matter hereof.

13.    Consent to Jurisdiction; Waiver of Jury Trial.

Each party hereby waives, and shall not assert as a defense in any legal dispute, that (a) such person is not personally subject to the jurisdiction of the Chosen Courts for any reason, (b) such legal proceeding may not be brought or is not maintainable in the Chosen Courts, (c) such person’s property is exempt or immune from execution, (d) such legal proceeding is brought in an inconvenient forum or (e) the venue of such legal proceeding is improper.

TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS LETTER AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT. FURTHERMORE, NO PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED. The Sponsor acknowledges and agrees that Footprint may seek specific performance of the Sponsor’s obligation to fund the Aggregate Commitment in accordance with Section 1 of this letter agreement.
