3.A certificate containing certain factual representations and covenants of the Company, and CHMI Sub-REIT, Inc., a Maryland corporation (“Sub-REIT”), (the “Officer’s Certificate”) relating to, among other things, the past, current, and proposed operations of the Company and the entities in which it holds a direct or indirect interest.

4.A copy of the Registration Statement.

5.A copy of the Merger Agreement.

6.Such other documentation or information provided to us by the Company, as we have deemed necessary or appropriate as a basis for our opinion set forth herein.

Although we have made such inquiries and performed such investigations as we have deemed necessary for purposes of our opinion, we have not independently verified all of the facts, representations and covenants set forth in the Officer’s Certificate, the Registration Statement, the Merger Agreement or in any other document.

We have relied on the factual statements, representations and covenants of the Company and Sub-REIT contained in the Officer’s Certificate, the Registration Statement, the Merger Agreement and other documents. We have assumed that such factual statements, representations and covenants are true, accurate, and complete, without regard to any qualification as to knowledge or belief.

Our opinion is conditioned on, among other things, the initial and continuing accuracy of the factual information, covenants and representations set forth in the Registration Statement, the Merger Agreement and the Officer’s Certificate and the representations made by representatives of the Company and Sub-REIT, without regard to any qualifications therein. Any change or inaccuracy in the facts referred to, set forth or assumed herein or in the Officer’s Certificate may affect our conclusions set forth herein.

Our opinion is also based on the correctness of the following assumptions: (i) the Company and each of the entities in which the Company holds a direct or indirect interest have been and will continue to be operated in accordance with the laws of the jurisdictions in which they were formed and in the manner described in the relevant organizational documents, (ii) there will be no changes in the applicable laws of the State of Maryland or of any other jurisdiction under the laws of which any such entity has been formed, and (iii) each of the written agreements to which the Company or any such entity is a party will be implemented, construed and enforced in accordance with its terms.

In rendering our opinion, we have also considered the applicable provisions of the Internal Revenue Code of 1986 (the “Code”), the Treasury Regulations promulgated thereunder, judicial decisions, administrative rulings and other applicable authorities, in each case as in

effect on the date hereof. The statutory provisions, regulations, decisions, rulings and other authorities on which this opinion is based are subject to change, and such changes could apply retroactively. A material change that is made after the date hereof in any of the foregoing bases for our opinion could affect our conclusions set forth herein.

In our examination, we have assumed (i) the legal capacity of all natural persons, (ii) the genuineness of all signatures, (iii) the authenticity of all documents submitted to us as originals, (iv) the conformity to original documents of all documents submitted to us as certified, conformed, or photostatic copies, and (v) the authenticity of the originals of such copies.

This opinion shall not be construed as or deemed to be a guaranty or insuring agreement. Opinions of special tax counsel represent only special tax counsel’s best legal judgment and are not binding on the Internal Revenue Service (“IRS”) or on any court. Accordingly, no assurance can be given that the IRS will not challenge the conclusions of the opinion set forth herein or that such a challenge would not be successful.

Based on and subject to the foregoing, we are of the opinion that, commencing with the Company’s taxable year ended December 31, 2020, the Company has been organized and operated in conformity with the requirements for qualification and taxation as a real estate investment trust (a “REIT”) under the Code, and its actual and proposed method of operation will enable the Company to meet, through the Company Merger Effective Time, the requirements for qualification and taxation as a REIT under the Code.

Other than as expressly stated above, we express no opinion on any issue relating to the Company or to any investment therein or under any other law. Furthermore, the Company’s qualification as a REIT will depend upon the Company’s meeting, in its actual operations, the applicable asset composition, source of income, stockholder diversification, distribution and other requirements of the Code and Treasury Regulations necessary for a corporation to qualify as a REIT. We will not review these operations and no assurance can be given that the actual operations of the Company and any applicable affiliates will meet these requirements or the representations made to us with respect thereto. This opinion letter is being furnished to you solely in connection with the Registration Statement and is not to be used by any other person or for any other purpose without our prior written consent.

This opinion is expressed as of the date hereof, and we are under no obligation to supplement or revise our opinion to reflect any legal developments or factual matters arising subsequent to the date hereof, or the impact of any information, document, certificate, record, statement, representation, covenant, or assumption relied upon herein that becomes incorrect or untrue.

We hereby consent to the filing of this opinion with the SEC as an exhibit to the Registration Statement, and to the references to Mayer Brown LLP under the captions “U.S.
