2 1. Purchase and Sale of Preferred Stock. 1.1. Sale and Issuance of Preferred Stock. (a) The Company shall have adopted and filed with the Secretary of State of the State of Delaware on or before the Initial Closing (as defined below) the Fifth Amended and Restated Certificate of Incorporation in the form of Exhibit B attached to this Agreement (the “Restated Certificate”). (b) Subject to the terms and conditions of this Agreement, each Purchaser agrees to purchase at the applicable Closing (as defined below) and the Company agrees to sell and issue to each Purchaser at the applicable Closing that number of shares of Series A Preferred Stock set forth opposite each Purchaser’s name on Exhibit A, at a purchase price of $4.390563 per share of Series A Preferred Stock. The shares of Series A Preferred Stock in each case issued to the Purchasers pursuant to this Agreement shall be referred to in this Agreement as the “Series A Shares.” 1.2. Closing; Delivery. (a) The initial purchase and sale of the Shares shall take place remotely via the exchange of documents and signatures on the date hereof, or such other time and place as the Company and the Purchasers mutually agree upon, orally or in writing (which time and place are designated as the “Initial Closing”). In the event there is more than one closing, the term “Closing” shall apply to each such closing unless otherwise specified. (b) At each Closing, the Company shall deliver to each Purchaser a certificate representing the Shares (or evidence of issuance of the Shares that are uncertificated) being purchased by such Purchaser at the Closing against payment of the purchase price therefor by wire transfer to a bank account designated by the Company, by cancellation or conversion of indebtedness or other convertible securities of the Company to Purchaser, including interest, or by any combination of such methods. 1.3. Share Exchange. (a) Subject to the terms and conditions hereof, in the event that a Purchaser, together with its Affiliates (each such Purchaser, a “Participating Purchaser”) (i) purchases Series A Shares; (ii) converts SAFEs or Notes identified on Exhibit A as “Qualifying Convertibles”, (iii) provides support; or (iv) provides equivalent value through a binding commercial arrangement (any of (i) through (iv), the “Participation Requirement”), in each case, in an amount equal to or greater than the Minimum Participation Amount (as defined below), then each Participating Purchaser holding Common Stock shall be entitled to exchange (the “Common Stock Exchange”) a number of shares of Common Stock for Class C Common Stock (the “Exchange Stock”), on a 1:1 basis, and each Participating Purchaser holding a warrant for Common Stock shall be entitled to exchange each such warrant for a warrant to purchase a corresponding number of shares of Exchange Stock (the “Warrant Exchange” and together with

3 the Common Stock Exchange, the “Share Exchange”). Each Share Exchange shall be treated as a separate transaction, and each Share Exchange shall be deemed a separate issuance. (b) Any Share Exchange pursuant to this Section 1.3 shall be deemed to have been made effective automatically and immediately upon the Closing in which an Exchanging Purchaser together with its Affiliates fulfills the Participation Requirement and other terms provided herein. Each Exchanging Purchaser participating in the Share Exchange shall surrender all of such Exchanging Purchaser’s certificates, if any, for such Exchanging Purchaser’s shares of Common Stock being exchanged for Exchange Stock in the Share Exchange (or, if such Exchanging Purchaser alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate), and surrender any warrants being exchanged in the Warrant Exchange. The Company shall, as soon as reasonably practicable thereafter, issue and deliver to such Exchanging Purchaser or any of such Exchanging Purchaser’s Affiliates participating in the Share Exchange a certificate or certificates for the number of shares of Class C Common Stock to which such holder shall be entitled in connection with the Share Exchange and a replacement warrant to which such holder shall be entitled in connection with the Warrant Exchange. 1.4. Conversion and Termination of Convertible Securities. (a) Participating Security Holders. Subject to the terms and conditions hereof, in the event that a Participating Purchaser is a Safe Investor or Note Holder (the “Participating Security Holders”), then at the Initial Closing the Participating Security Holders shall be entitled to exchange all Participating Security Holders’ Convertible Securities (as defined below) into the number of shares of Series A Prime-1 Preferred Stock or Series A Prime-2 Preferred Stock, as applicable, determined by dividing the value of all of the Participating Security Holders’ Convertible Securities (including outstanding principal, interest or any other amounts, in each case as applicable) by either the Series A Prime-1 Original Issue Price or Series A Prime-2 Original Issue Price, as applicable to the issuance of Series A Prime-1 Preferred Stock or Series A Prime-2 Preferred Stock shown on Exhibit A hereto, and each Participating Purchaser providing other consideration in exchange for shares of Series A Prime-2 Preferred Stock as indicated on Exhibit A shall be issued such shares of Series A Prime-2 Preferred Stock. (b) Non-Participating Security Holders. Subject to the terms and conditions hereof, at the Initial Closing and concurrently with the exchange of all Convertible Securities held by Participating Security Holders, all other Convertible Securities will automatically and without any action on the part of such Investor convert into the number of shares of Series A-1 Preferred Stock or Series A-2 Preferred Stock, as applicable, determined by dividing the amount of each such Convertible Security (including outstanding principal, interest or any other amounts, in each case as applicable) by either the Series A-1 Original Issue Price or Series A-2 Original Issue Price, as applicable to the issuance of Series A-1 Preferred Stock or Series A- 2 Preferred Stock shown on Exhibit A hereto.

4 (c) By executing and delivering this Agreement, each Purchaser holding one or more Safes and/or Notes issued by the Company prior to the date of this Agreement (each, regardless of whether held by a Purchaser or not, a “Convertible Security” and, collectively, regardless of whether held by a Purchaser or not, the “Convertible Securities”) hereby irrevocably agrees that: (i) The aggregate face amount of all Convertible Securities held by such Purchaser is set forth on Exhibit A under the column heading “Convertible Securities”; (ii) Such Purchaser is the sole owner of all right, title and interest in and to the Convertible Securities corresponding to the amounts shown opposite such Purchaser’s name on Exhibit A; (iii) At the Initial Closing, each Participating Purchaser’s Convertible Securities will automatically and without any action on the part of such Purchaser be exchanged for the number of shares of Series A Prime-1 Preferred Stock or Series A Prime-2 Preferred Stock set forth opposite such Purchaser’s name under the column headings “Series A Prime-1 Preferred” or “Series A Prime-2 Preferred”, on Exhibit A; (iv) At the Initial Closing, all other Convertible Securities will automatically and without any action on the part of such Purchaser convert into the number of shares of, Series A-1 Preferred Stock and/or Series A-2 Preferred Stock, as applicable, set forth opposite such Purchaser’s name under the column headings “Series A-1 Preferred’ or “Series A-2 Preferred”, on Exhibit A (collectively, the Series A Prime-1 Preferred Stock, Series A Prime-2 Preferred Stock, Series A-1 Preferred Stock and Series A-2 Preferred Stock may be referred to as the “Convertible Security Shares”), regardless of whether any such Convertible Securities or an affidavit of loss therefor is actually delivered in original or other form to the Company, and any original Convertible Securities held by (or delivered electronically or otherwise to) the Company may be cancelled (and marked cancelled) by the Company upon or following the Initial Closing; (v) The Company and its Affiliates and agents shall be entitled to deduct and withhold from the amounts deliverable pursuant to Purchaser’s Convertible Securities (including any Convertible Security Shares otherwise issuable with respect thereto) such amounts, if any, as are required to be deducted and withheld under the Code or any other applicable tax law. To the extent that amounts are so deducted and withheld and duly paid over to the appropriate tax authority, such withheld amounts shall be treated for all purposes of the Transaction Agreements as having been delivered to the person in respect of whom such deduction and withholding was made. Each person holding Convertible Securities shall, upon request, use its commercially reasonable efforts to provide the applicable withholding agent with all necessary tax forms, including a duly executed IRS Form W-9 or appropriate version of IRS Form W-8, as applicable. Prior to withholding any amounts pursuant to this Section 1.4(c)(iv), the Company (and its Affiliates and agents) shall use commercially reasonable efforts to notify Purchaser, and the Company and Purchaser shall cooperate in good faith to reduce or eliminate any such withholding. (vi) As to such Purchaser, such Purchaser’s Convertible Security Shares are issued in full and complete discharge and satisfaction of all obligations of the Company

5 (including outstanding principal, interest or any other amounts) under such Purchaser’s Convertible Securities, and such Convertible Securities will be terminated and of no further force or effect automatically immediately upon the Initial Closing. (d) The Company and each Purchaser holding a Convertible Security hereby agree, on behalf of themselves and all holders of Convertible Securities, that all Convertible Securities hereby are and will be deemed for all purposes to have been amended and modified by virtue hereof to the full extent necessary to permit and facilitate their conversion as provided in this Agreement into Convertible Security Shares, to fix the conversion price (as defined therein) as provided in Exhibit A, and, immediately upon the Initial Closing, all Convertible Securities shall be deemed terminated in full and null, void and of no further force or effect; provided that the foregoing will not impair the right of the holder of a Convertible Security to receive the applicable number of Convertible Security Shares shown opposite such holder’s name on Exhibit A. 1.5.

The Business Plan was prepared in good faith; however, the Company does not warrant that it will achieve any results projected in the Business Plan.

Representations and Warranties of the Purchasers. Each Purchaser hereby represents and warrants to the Company, severally and not jointly, that: 3.1. Authorization. The Purchaser has full power and authority to enter into the Transaction Agreements. The Transaction Agreements to which the Purchaser is a party, when executed and delivered by the Purchaser, will constitute valid and legally binding obligations of the Purchaser, enforceable against such Purchaser in accordance with their terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, and

14 as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies, or (b) to the extent the indemnification provisions contained in the Amended and Restated Stockholders’ Agreement may be limited by applicable federal or state securities laws. 3.2. Purchase Entirely for Own Account. This Agreement is made with the Purchaser in reliance upon the Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Shares to be acquired by the Purchaser will be acquired for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any of the Shares. 3.3. Disclosure of Information. The Purchaser has had an opportunity to discuss the Company’s business, management, financial affairs and the terms and conditions of the offering of the Shares with the Company’s management and has had an opportunity to review the Company’s facilities. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 2 of this Agreement or the right of the Purchasers to rely thereon. 3.4. Restricted Securities. The Purchaser understands that the Shares have not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed herein. The Purchaser understands that the Shares are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Shares indefinitely unless they are registered with the Securities and Exchange Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Shares, or the Common Stock into which it may be converted, for resale except as set forth in the Amended and Restated Stockholders’ Agreement. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Shares, and on requirements relating to the Company which are
