3.Representations and Warranties of the Purchasers. Each Purchaser represents and warrants to the Company that:

(a)Authority. Such Purchaser is duly incorporated or formed, validly existing, and in good standing under the laws of the jurisdiction of its incorporation or formation, and has all requisite corporate or limited liability company, as applicable, power and authority to execute and deliver this Agreement, the LLC Agreement and the other JV Agreements to which it is a party and to perform such Purchaser’s obligations hereunder and thereunder.

(b)Authorization; Enforceability. The execution and delivery by such Purchaser of this Agreement, the LLC Agreement and the other JV Agreements to which it is a party and the consummation by such Purchaser of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate or limited liability company, as applicable, action on the part of such Purchaser. This Agreement has been duly executed and delivered by such Purchaser and constitutes, and when the LLC Agreement has been duly executed and delivered by such Purchaser such agreement will constitute, a legal, valid, and binding obligation of the Purchaser, enforceable against such Purchaser in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium, and other similar laws of general applicability relating to or affecting creditors’ rights or general equity principles (regardless of whether considered at law or in equity).

(c)No Conflicts; Consents. The execution and delivery by such Purchaser of this Agreement, the LLC Agreement and the JV Agreements to which such Purchaser is a party do not, and the consummation by such Purchaser of the transactions contemplated hereby and thereby will not (with or without the giving of notice, the lapse of time, or both), contravene, conflict with, or result in a breach or violation of, or a default under (i) such Purchaser’s certificate of incorporation or certificate of formation, as applicable, by-laws, or other constitutive documents; (ii) any judgment, order, decree, statute, law, ordinance, rule, or regulation applicable to such Purchaser; or (iii) any material contract, agreement, or instrument to which such Purchaser is a party or otherwise bound. No consent, approval, waiver, or authorization is required to be obtained by such Purchaser from any Person (including any governmental authority) in connection with the execution, delivery, and performance by such Purchaser of this Agreement, the LLC Agreement, and the consummation of the transactions contemplated hereby and thereby.

(d)No Registration. The Purchaser understands and acknowledges that the Purchased Interests have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any other jurisdiction and the offer and sale of the Purchased Interests are being made in reliance on one or more exemptions for private offerings under Section 4(a)(2) of the Securities Act and certain exemptions from applicable state securities laws. No sale, transfer, assignment, or other disposition (“Transfer”), whether with or without consideration and whether voluntarily or involuntarily or by operation of law, of any of the Purchased Interests is permitted unless such Transfer is registered under the Securities Act and other applicable securities laws, or an exemption from such registration is available.

With the assistance of such Purchaser’s own professional advisors (to the extent that the Purchaser has deemed such assistance appropriate), such Purchaser has undertaken their own legal, tax, accounting, financial, and other evaluation of the merits and risks of an investment in such Purchased Interests in light of such Purchaser’s own circumstances and financial condition and has concluded that they are capable of bearing the economic risk of holding the Purchased Interests for an indefinite period of time, have adequate means to provide for their current needs and contingencies (after giving effect to an investment in the Purchased Interests), and can afford to suffer a complete loss of such Purchaser’s investment in the Company.

(f)Lack of Liquidity. Such Purchaser acknowledges and agrees that no market for the resale of any of the Purchased Interests currently exists, and no such market may ever exist. The Purchased Interests are subject to the restrictions on transfer set out in the LLC Agreement.

Such Purchaser confirms their understanding that such Purchaser must bear the economic and financial risk of an investment in the Purchased Interests for an indefinite period of time.

(g)Information Concerning the Company; Access to Management.

Such Purchaser and such Purchaser’s representatives have been afforded a full opportunity to ask questions of and receive answers from the manager of the Company about the business and affairs of the Company, and to examine all such documents, materials, and information concerning the Company as such Purchaser or such representatives deem to be necessary or advisable in order for such Purchaser to reach an informed decision concerning whether to make an investment in the Company. Such Purchaser confirms that all of such Purchaser’s and any of such Purchaser’s representatives’ requests or questions have been answered to their full satisfaction and no request or question has been denied or remains unfulfilled or unanswered.

(i)Such Purchaser is not relying on (and will not at any time rely on) any communication (written or oral) of the Company or any of its affiliates or representatives as investment advice or as a recommendation to purchase the Purchased Interests, it being understood that any information and explanations related to the terms and conditions of the Purchased Interests shall not be considered investment advice or a recommendation to purchase the Purchased Interests.

(ii)Such Purchaser confirms that the Company has not (A) given any guarantee or representation as to the potential success, return, effect, or benefit (either legal, regulatory, tax, financial, accounting, or otherwise) of an investment in the Purchased Interests; or (B) made any representation to such Purchaser regarding the legality of an investment in the Purchased Interests under applicable legal investment or similar laws or regulations. In deciding to purchase the Purchased Interests, such Purchaser is not relying on the advice or recommendations of the Company and such Purchaser has made their own independent decision that an investment in the Purchased Interests is suitable and appropriate for such Purchaser.

(iii)Other than the representations and warranties of the Company set forth in Section 4, neither the Company nor any other Person makes any representation or warranty, expressed or implied, as to the accuracy or completeness of the information provided or to be provided to such Purchaser by or on behalf of the Company or related to the transactions contemplated hereby, and nothing contained in any documents provided or statements made by or on behalf of the Company to such Purchaser is, or shall be relied upon as, a promise or representation by the Company or any other Person that any such information is accurate or complete.

Such Purchaser is purchasing the Purchased Interests for such Purchaser’s own benefit and account for investment purposes only, and not with a view to, or in connection with, any public offering, resale, or distribution thereof. Such Purchaser will not sell, assign, transfer, or otherwise dispose of any of the Purchased Interests, or any interest therein, in violation of the Securities Act or any applicable state securities law. Such Purchaser understands that the Company is relying upon the Purchaser’s representations and agreements contained in this Agreement for the purpose of determining whether the offering of the Purchased Interests is exempt from registration under the Securities Act and all applicable state securities laws.

(k)No General Solicitation. Such Purchaser confirms that they have not been offered the Purchased Interests by any means of general solicitation or general advertising.

(l)Closing Date Reaffirmation. Such Purchaser understands that, unless the Purchaser notifies the Company in writing to the contrary at or before the Closing, each of the Purchaser’s representations and warranties contained in this Agreement will be deemed to have been reaffirmed and confirmed as of the Closing Date, taking into account all information received by such Purchaser.
