treated as partnerships or as “disregarded entities” for U.S. federal income tax purposes and not as corporations, associations taxable as corporations or as publicly traded partnerships that are taxable as corporations. 
 3.9 To the Trust’s knowledge, the Trust qualifies as a “domestically controlled qualified investment entity” within the
meaning of Section 897(h) of the Code. 
 3.10 The Trust covenants and agrees with the Purchaser that the Purchaser may
rely on the representations and warranties of the Trust and its subsidiaries that shall be set forth in the underwriting agreement to be entered into between the Trust and the representative(s) of the several underwriters of the IPO named therein

 4.1 Purchaser
is an “accredited investor” as that term is defined in Rule 501 under the Securities Act.

accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general principles of equity. The purchase by
Purchaser of the Shares does not conflict with the organizational documents of Purchaser or with any material contract under which Purchaser or its property is bound, or any laws or regulations or decree, ruling or judgment of any court applicable
to Purchaser or its property. 
 4.5 Purchaser understands and acknowledges that the offering of the Shares pursuant to this
Agreement will not be registered under the Securities Act on the grounds that the offering and sale of the Shares is exempt from registration under the Securities Act pursuant to Section 4(2) thereof and exempt from registration pursuant to
applicable state securities or blue sky laws, and that the Trust’s reliance upon such exemptions is predicated upon Purchaser’s representations and warranties set forth in this Agreement. Purchaser understands and acknowledges that the

Purchaser’s investment in the Shares, which have been requested by Purchaser and (b) Purchaser has had adequate opportunity to ask questions of, and receive answers from, the officers, employees, agents, accountants and representatives of
the Trust concerning the business, operations, financial condition, assets and liabilities of the Trust and all other matters relevant to its investment in the Shares.

arising or that may arise out of such claim, action or proceeding.

consummation of the transactions contemplated hereby if (a) prior to the closing of the IPO, the Underwriting Agreement is terminated pursuant to its terms or (b) the Closing has not occurred within 180 days following the date hereof. The
