    NOW, THEREFORE, in consideration of the foregoing and the agreements set forth below, and for other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Parties hereby agree with each other as follows:

1.Payment of Interest.

(a)GGHI and Atlas acknowledge and agree that as consideration for Atlas’ continued credit support with respect to the L/Cs, GGHI shall pay interest (the “Interest Payment”) on the aggregate amount of the outstanding L/C Obligations (the “Aggregate Principal Amount”), which as of the date hereof is equal to $8,624,245, at the rate of 8.5% per annum (the “Interest Rate”), with interest calculated on a per diem basis based on the number of days in the applicable measurement period, which Interest Payments shall be net of any interest otherwise actually received by Atlas from the issuing bank of the L/Cs on any cash collateral posted by Atlas in respect of the L/Cs during the applicable measurement period. Other than as provided in Section 2(b), all Interest Payments shall be in the form of Class A Shares.

(b)Commencing on the signing of this Agreement, and continuing during the “Term” (as defined in Section 4 below) of this Agreement, the Company shall continue to make Interest Payments to Atlas on the Aggregate Principal Amount on a calendar quarter basis (each, a “Quarterly Period”), which quarterly Interest Payments shall be in arrears. In addition, GGHI agrees to reimburse Atlas for the documented out-of-pocket bank fees and expenses for each Quarterly Period in connection with any Outstanding L/C Obligations (such fees and expenses, the “L/C Fee Reimbursement”) maintained by Atlas for the benefit of GGHI, which quarterly L/C Fee Reimbursement shall be in the form of Class A Shares (other than as provided in Section 2(b) and shall be in arrears.

(c)The payments in respect of (i) the L/C Extension Payment (as defined below) shall be issued within seven (7) Business Days of the Effective Date, and (ii) the Interest Payment and L/C Fee Reimbursement for each Quarterly Period shall be issued within seven (7) Business Days after the end of the applicable Quarterly Period. As used herein, the term “Business Days” means any day when federally chartered commercial banks in New York City are open for business except Saturdays and Sundays.

(d)Unless Atlas provides instructs otherwise, any payment to Atlas hereunder shall be made to each Atlas Holder based on its pro rata percentage set forth opposite its name on Schedule A attached hereto.

2.Class A Shares.

(a)The number of Class A Shares to be issued to Atlas in respect of the L/C Extension Payment, an Interest Payment, or an L/C Fee Reimbursement shall be calculated by dividing the applicable amount of the L/C Extension Payment, such Interest Payment, or such L/C Fee Reimbursement by the Applicable Price. “Applicable Price” shall mean: (i) in respect of the L/C Extension Payment, the lower of (but no less than) (A) the Nasdaq Official Closing Price of the Class A Shares (as reflected on Nasdaq.com) immediately preceding the signing of this Agreement or (B) the average Nasdaq Official Closing Price of the Class A Shares (as reflected on Nasdaq.com) for the five (5) trading days immediately preceding the signing of this Agreement, and (ii) in respect of an Interest Payment or L/C Fee Reimbursement for each Quarterly Period, the volume weighted average price of the Class A Shares as reported on the Nasdaq Global Select Market, or any other market or exchange where the Class A Shares are listed or traded (rounded to the nearest second decimal place), for all trading days during the then ended Quarterly Period for which any L/C Obligations were outstanding.

(b)Notwithstanding anything to the contrary contained in this Agreement, the total cumulative number of Class A Shares that may be issued to Atlas hereunder shall not exceed 19.99% of the sum of the number of Class A Shares and shares of Class B common stock, $0.0001 par value per share, of the Company (“Class B Shares” and, together with the Class A Shares, collectively, the “Common Stock”) outstanding as of the date hereof (the “Cap”). In the event that the Class A Shares issuable hereunder would exceed the Cap (any such Class A Shares, the “Excess Shares”), then any Interest Payments or L/C Fees Reimbursement payable hereunder and represented by the Excess Shares shall be paid in cash.

(c)At any time after the signing of this Agreement, upon Atlas’s request, GGHI will enter into a customary registration rights agreement with Atlas that provides for demand and piggyback registrations in respect of all Class A Shares (and other equity securities of GGHI convertible into Class A Shares, including Class B Shares) held by Atlas or any of its affiliates.

(d)The Company shall cause its transfer agent to issue all Class A Shares to Atlas hereunder in book entry form to such account(s) as may be designated in writing by Atlas from time to time and all Class A Shares issued hereunder shall bear an appropriate restrictive legend.

3.Term and Termination.

(a)The term of this Agreement shall commence on the Effective Date and shall continue until such time as Atlas is no longer providing credit support with respect to the L/Cs, because such credit support is no longer required, or the L/Cs have been terminated, in each case, with no remaining obligations of or liability to Atlas with respect thereto. This Agreement may be terminated at any time upon the mutual written agreement of the Parties.

(b)Atlas agrees to keep the L/Cs in place until their respective Renewal Dates and to provide GGHI with notice at least 45 days prior to the effective date of the termination or non-renewal of any such L/C, in each case, other than in the event of a Material

Breach Event (as defined below). Upon receipt of such notice from Atlas, or upon a Material Breach Event, GGHI will direct its bank to issue new letters of credit to replace the L/Cs, use commercially reasonable efforts to effect the replacement of such L/Cs and otherwise cooperate with Atlas in good faith to cause the L/Cs to be terminated. For the avoidance of doubt, Atlas’s right to terminate the L/Cs is not contingent upon the replacement of the L/Cs.

(c)At any time on or after the occurrence of a Material Breach Event, Atlas shall have the right to cause the L/Cs to be terminated and to exercise all rights and remedies available as provided herein. “Material Breach Event” means the Company is in material breach of any representation, warranty or covenant under this Agreement (which shall include the Company’s failure to timely pay the L/C Extension Payment, any Interest Payment or any L/C Fee Reimbursement) and (i) if such breach is subject to cure, thirty (30) days have passed after Atlas has provided written notice of such breach to the Company, which written notice describes in reasonable detail the nature of such breach, and such breach has not been cured within such thirty (30) day period, or (ii) if such breach is not capable of being cured, five (5) days have passed after Atlas has provided prior written notice to the Company if the L/Cs are drawn on in whole or in part at any time and the Company fails to reimburse and make whole Atlas and its affiliates within ten (10) days of such event.

(d)Atlas and the Company acknowledge that they have previously entered into that certain letter agreement, dated as of March 18, 2021 (the “L/C Replacement Agreement”), pursuant to which the Company agreed, upon Atlas’ request, to direct the Company’s bank to issue letters of credit to replace all or a portion of the L/Cs, effective upon the consummation by the Company of a qualifying financing transaction that results in net proceeds to the Company of at least $10,000,000 (a “Qualifying Financing”). Notwithstanding that the parties acknowledge that a Qualifying Financing has occurred, Atlas agrees that so long as (i) the Company has made a payment to Atlas equal to $1,369,990.00 in accordance with the terms of this Agreement, in the form of Class A Shares, the exact number of which is to be calculated pursuant to Section 2(a) above (the “L/C Extension Payment”) as further consideration for Atlas to enter into this Agreement and maintain the L/Cs in accordance with the terms hereof, (b) is not in default of its obligations under this Agreement and (c) there is not a Material Breach Event, Atlas shall not request or otherwise require the Company to replace the L/Cs pursuant to the L/C Replacement Agreement with an effective date that is prior to the respective Renewal Dates of the L/Cs. The Company acknowledges the Company’s obligation, as provided in the L/C Replacement Agreement, and hereby agrees, to reimburse and make whole Atlas and its affiliates if the L/Cs are drawn on in whole or in part at any time and agree that such obligation remains in full force and effect.
