Interests will be duly authorized, issued and sold to the New Trust Preferred Interest Holders in accordance with the Registration Statement and the LLC Agreement, (xvi) that after the issuance and sale of any Outstanding Trust Common Interests or New Trust Common Interests under the Registration Statement and the LLC Agreement, the aggregate number of Trust Common Interests issued by the LLC will not exceed 500,000,000, and (xvii) that after the issuance and sale of any Outstanding Trust Preferred Interests or New Trust Preferred Interests under the Registration Statement and the LLC Agreement, the aggregate number of Trust Preferred Interests issued by the LLC will not exceed 50,000,000. We have not participated in the preparation of the Registration Statement or the Prospectus and assume no responsibility for their contents, other than this opinion.

This opinion is limited to the laws of the State of Delaware (excluding the blue sky laws of the State of Delaware), and we have not considered and express no opinion on the laws of any other jurisdiction, including federal laws and rules and regulations relating thereto. Our opinions are rendered only with respect to Delaware laws and rules, regulations and orders thereunder which are currently in effect.

Based upon the foregoing, and upon our examination of such questions of law and statutes of the State of Delaware as we have considered necessary or appropriate, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that:

1.The LLC has been duly formed and is validly existing in good standing as a limited liability company under the Delaware Limited Liability Company Act (6 Del. C. § 18-101, et seq.).

2.The Outstanding Trust Common Interests have been or will be validly issued and, subject to the qualifications set forth in paragraph 6 below, fully paid and nonassessable limited liability company interests in the LLC.

3.The Outstanding Trust Preferred Interests have been or will be validly issued and, subject to the qualifications set forth in paragraph 6 below, fully paid and nonassessable limited liability company interests in the LLC.

4.The New Trust Common Interests will be validly issued and, subject to the qualifications set forth in paragraph 6 below, fully paid and nonassessable limited liability company interests in the LLC.

5.The New Trust Preferred Interests will be validly issued and, subject to the qualifications set forth in paragraph 6 below, fully paid and nonassessable limited liability company interests in the LLC.

6.A Trust Interest Holder shall not be obligated personally for any of the debts, obligations or liabilities of the LLC, whether arising in contract, tort or otherwise, solely by reason of being a member of the LLC, except as a Trust Interest Holder may be obligated to repay any funds wrongfully distributed to it. We note that a Trust Interest Holder may be obligated pursuant to the LLC Agreement to provide the Transfer Agent sufficient indemnity in connection with the issuance of replacement Trust Interest Certificates.

We consent to the filing of this opinion with the SEC as an exhibit to the Registration Statement. In addition, we hereby consent to the use of our name under the heading "Legal Matters" in the Prospectus. In giving the foregoing consents, we do not thereby admit that we come within the category of persons or entities whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the SEC thereunder.

Very truly yours,

/s/ Richards, Layton & Finger, P.A.
