incorporated, validly existing and in good standing under the laws of the State of Delaware; (b) has all requisite corporate power and authority to (i) own its assets and to carry on its business as currently conducted and
(ii) execute, deliver and perform its obligations under this Agreement and each Related Agreement to which it is a party; (c) is duly qualified and is in good standing under the laws of each jurisdiction where its ownership, lease or
operation of properties or the conduct of its business requires such qualification; (d) is in compliance with all applicable laws, writs, injunctions and orders; and (e) has all requisite governmental licenses, authorizations, consents and
approvals to operate its business as currently conducted; except in each case referred to in clause (c), (d) or (e), to the extent that failure to do so would not reasonably be expected to have, individually or in the aggregate, a Material Adverse
Effect. 
 SECTION 2.2 Authorization; No Contravention. The execution, delivery and
performance by the Company of this Agreement and each Related Agreement to which it is a party, the issuance and sale of the Series A Preferred Shares pursuant to this Agreement, and the issuance of the Warrants and, upon exercise in accordance with
the terms and conditions thereof, the issuance and sale of the Warrant Shares, has been duly authorized by all necessary corporate action on the part of the Company. None of the execution, delivery or performance by the Company of each such
agreement to which the Company is a party, nor the consummation of the Transactions, will contravene the terms of any of its Organizational Documents. The Company is not: (a) in violation of its certificate of incorporation or bylaws; or
(b) in default in the performance or observance of any obligation, agreement, covenant or condition under any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which the Company is a party or by which
its properties may be bound, except, in the case of clause (b), such defaults or violations, as the case may be, as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

SECTION 2.3 Governmental Authorization. No approval, consent, exemption, authorization, or
other action by, or notice to, or filing with, any Governmental Authority is required in connection with the execution, delivery or performance by, or enforcement against, the Company of this Agreement or any Related Agreement to which it is a
party, except: (a) such as have been obtained or made, or will be obtained or made, by the Company under the applicable state securities or Blue Sky laws; (b) as shall have been obtained or made prior to the Closing Date by the Company and
which are in full force and effect on the Closing Date; and (c) where the failure to obtain any such approval, consent, exemption, authorization, or other action by, or notice to, or filing with, any Governmental Authority as would not impair,
in any material respect, the ability of the Company to consummate the Transactions or perform its obligations under this Agreement or the Related Agreements to which it is a party.

 SECTION 2.4 Binding Effect. This Agreement and each other
Related Agreement to which it is a party has been duly executed and delivered by the Company. This Agreement and each other Related Agreement to which it is a party constitutes a legal, valid and binding obligation of the Company, enforceable

SECTION 2.5 Capitalization. 

(a) The Company has filed the Certificate of Designation with the Secretary of State of the State of Delaware prior to the Closing. Immediately
prior to the consummation of the Transactions, the authorized Equity Interests of the Company consisted of (i) 450,000,000 shares of Class A common stock (“Common Stock”), with a par value of $0.0001 per share, and (ii)
1,000,000 shares of preferred stock, with a par value of $0.0001 per share, of which 165,000 shares have been designated as “Series A Non-Convertible Senior Preferred Stock” with the Stated Value,
which are sufficient to allow for the payment of dividends in kind, in each case, none of which were held in treasury or issued and outstanding. As of February 17, 2022, 197,413,999 shares of Common Stock were issued and outstanding, and, as of
the date hereof, no shares of preferred stock are issued and outstanding other than the preferred shares authorized and sold pursuant to this Agreement. Except for this Agreement and as disclosed on Schedule 2.5 of this Agreement, there are no
outstanding subscriptions, options, warrants, puts, calls, exchangeable or convertible securities or other similar rights, agreements or commitments relating to the issuance of capital stock to which the Company is a party obligating the Company to
issue, transfer or sell any shares or other equity interests of the Company or securities convertible into or exchangeable for such shares or equity interests of the Company. 

(b) The Series A Preferred Shares, when issued and delivered and paid for in compliance with the provisions of this Agreement, and the Warrant
Shares, when issued and delivered and paid for in compliance with the provisions of the Warrant Agreement and the Warrants, as applicable, shall be duly authorized, validly issued, fully paid and
non-assessable and free of restrictions on transfer except for restrictions on transfer arising under (i) applicable securities Laws, (ii) the Company’s Organizational Documents, (iii) the
Related Agreements and (iv) liens, encumbrances and other restrictions created by or imposed by any applicable Purchaser. 
 (c) As of
the Closing and the issuance of the Series A Preferred Shares, the Series A Preferred Shares shall, with respect to dividend rights and payment rights upon the Company’s liquidation, winding up or dissolution, rank senior to all other Equity
Interests of the Company, including any other class or series of its Equity Interests. 
 SECTION 2.6 Offering of
Securities. Neither the Company nor any Person acting on its behalf has taken any action (including any offering of any securities of the Company under circumstances which would require the integration of such offering with the offering of
the Series A Preferred Shares or the Warrants to be issued pursuant to this Agreement under the Securities Act, and the rules and regulations of the U.S. Securities and Exchange Commission promulgated thereunder) which would reasonably be expected
to subject the offering, issuance or sale of the Series A Preferred Shares or the Warrants to the Purchasers pursuant to this Agreement to the registration requirements of the Securities Act. 

SECTION 2.7 No Registration. The offer, issuance, sale and delivery of the Series A Preferred
Shares pursuant to this Agreement, and the offer, issuance, sale and delivery of the Warrants, and upon exercise of the Warrants pursuant to the terms and conditions of the Warrants and the Warrant Agreement, as applicable, the issuance, sale and
