 OF SUBSCRIBER 

Subscriber hereby represents and warrants to the Company and to each officer, director and agent of the Company as follows: 

2.01 Authority. Subscriber has full power and authority to execute and deliver this Agreement and to perform its
obligations hereunder, and the execution, delivery and performance by Subscriber of this Agreement has been duly authorized by all necessary action. 

  
 1 








 2.02 Binding Obligations. This Agreement has been duly and validly
executed and delivered by Subscriber and constitutes, or shall constitute, the binding obligation of Subscriber enforceable against Subscriber in accordance with its terms, subject to Creditors’ Rights. 

2.03 No Conflict. The execution, delivery and performance by Subscriber of this Agreement will not, with or without
the giving of notice or the passage of time, or both, (i) violate any provision of Law to which Subscriber is subject, (ii) violate any order, judgment or decree applicable to Subscriber, or (iii) conflict with, or result in a breach
or default under any instrument to which Subscriber is a party or by which any property of Subscriber is otherwise bound or subject, except where such conflict, breach or default would not reasonably be expected to, individually or in the aggregate,
prevent or materially delay the consummation of the transactions contemplated by this Agreement or to materially impair Subscriber’s ability to perform its obligations under the this Agreement or the LLC Agreement. 

2.04 Investment Entirely For Own Account. The Units acquired or to be acquired by Subscriber will be acquired for
investment for Subscriber’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof; Subscriber has no present intention of selling, granting any participation in, or otherwise distributing
the same; and Subscriber does not 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 Units. 

2.05 Unregistered Securities. Subscriber understands that the Units, at the time of issuance, will not be registered
under the Securities Act or other applicable federal or state securities laws and the rules and regulations promulgated thereunder. Subscriber also understands that the Units are being offered and sold pursuant to an exemption from registration
contained in the Securities Act based in part upon Subscriber’s representations contained in this Agreement. 
 2.06
Accredited Investor; Investment Experience. Subscriber is (a) an “accredited investor” as defined in Rule 501(a) under Regulation D of the Securities Act, a copy of which is attached hereto as Annex A.
Subscriber acknowledges that Subscriber is familiar with the business and financial condition, properties, operations and prospects of the Company, including the Sponsor’s ownership of a substantial amount of the issued and outstanding Units of
the Company and the Sponsor’s rights set forth in the LLC Agreement, and Subscriber has made all investigations which it deems necessary or desirable for deciding whether to invest in the Units. Subscriber has such knowledge and experience in
financial and business matters that Subscriber is capable of evaluating the merits and risks of an investment in the Units and of making an informed investment decision with respect to the purchase thereof and understands that (i) this
investment is suitable only for an investor which is able to bear the economic consequences of losing such investor’s entire investment, (ii) the acquisition of the Units hereunder is a speculative investment which involves a high degree
of risk of loss, which could include the loss of the Subscriber’s entire investment, and (iii) there are substantial restrictions on the transferability of, and there will be no public market for, the Units, and accordingly, it may not be
possible for Subscriber to liquidate Subscriber’s investment in case of emergency. 

  
 2 








 2.07 Restricted Securities. Subscriber understands that the Units to be
acquired by Subscriber may not be sold, transferred or otherwise disposed of without registration under the Securities Act or an exemption therefrom, and that in the absence of either an effective registration statement covering the Units or an
available exemption from registration under the Securities Act, the Units must be held indefinitely. Subscriber understands that the Company has no present intention of registering the Units to be acquired by Subscriber. Subscriber also understands
that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow Subscriber to transfer all or any portion of the Units to be acquired by it under
the circumstances, in the amounts or at the times Subscriber might propose. In particular, Subscriber is aware that the Units may not be sold pursuant to Rule 144 promulgated under the Securities Act unless all of the conditions of Rule 144 are met.
Among the conditions for use of Rule 144 may be availability of current information to the public about the Company. Such information is not now available and the Company has no plans to make such information available. 

2.08 Taxes. Subscriber has reviewed with its own Tax advisors the federal, state and local and the other Tax
consequences of an investment in Units and the transactions contemplated by this Agreement. Subscriber acknowledges and agrees that the Company is making no representation or warranty as to the federal, state, local or foreign Tax consequences to
Subscriber as a result of Subscriber’s acquisition of the Units or the transactions contemplated by this Agreement. Subscriber understands that it shall be responsible for its own Tax liability that may arise as result of Subscriber’s
acquisition of the Units. 
 ARTICLE 3 
 REPRESENTATIONS AND WARRANTIES 
 OF THE COMPANY 

The Company hereby represents and warrants to Subscriber as follows: 

3.01 Organization, Standing and Power. The Company is duly organized, validly existing and in good standing under
the laws of its state of organization, with full power and authority to conduct its business as it is currently being conducted and to own its assets and to consummate the transactions contemplated by this Agreement; and has secured any other
