The opinions set forth in this letter are premised on, among other things, the written factual representations of Host REIT and Host LP regarding the organization, ownership and operations of Host REIT that are contained in a letter to us dated as of the date hereof (the “Company Representation Letter”).

For purposes of rendering our opinions, although we have knowledge as to certain of the facts set forth in the above-referenced documents and although we have discussed the Company Representation Letter with the signatories thereto, we have not made an independent investigation or audit of the facts set forth in the Reviewed Documents or the Company Representation Letter. We consequently have relied upon the representations and statements of Host REIT and Host LP as to factual matters that are set forth or described in the Reviewed Documents and the Company Representation Letter, or incorporated by reference in the Registration Statement, and we have assumed that the information presented in such documents or otherwise furnished to us is accurate and complete in all material respects.

In this regard, we have assumed or obtained representations regarding (and, with your consent, are relying upon) the following:

(1) that (A) all of the representations and statements set forth in the Reviewed Documents and the Company Representation Letter are true, correct, and complete as of the date hereof, (B) any representation or statement made as a

April 16, 2019

Page 3

belief or made “to the knowledge of” or similarly qualified is correct and accurate, and that such representation or statement will continue to be correct and accurate, without such qualification, (C) each of the Reviewed Documents that constitutes an agreement, or each agreement described in a Reviewed Document or in the Company Representation Letter, is valid and binding in accordance with its terms, and (D) each of the obligations imposed by or described in the Reviewed Documents, including, without limitation, the obligations imposed under the Articles of Incorporation, have been and will continue to be performed or satisfied in accordance with their terms; provided that, notwithstanding any of the foregoing, we are not making any assumptions as to the accuracy or completeness with respect to statements in the Tax Disclosure describing provisions of U.S. federal income tax law that are covered by our opinion set forth below;

(2) the genuineness of all signatures, the proper execution of all documents, the authenticity of all documents submitted to us as originals, the conformity to originals of documents submitted to us as copies, and the authenticity of the originals from which any copies were made;

(3) that any documents as to which we have reviewed only a form were or will be duly executed without material changes from the form reviewed by us; and

(4) that Host REIT will utilize all appropriate “savings provisions” (including, without limitation, the provisions of Sections 856(c)(6), 856(c)(7), and 856(g) of the Internal Revenue Code of 1986, as amended (the “Code”), and the provision included in Section 856(c)(4) of the Code (flush language) allowing for the disposal of assets within 30 days after the close of a calendar quarter, and all available deficiency dividend procedures) available to a REIT under the Code in order to correct any violations of the applicable REIT qualification requirements of Sections 856 and 857 of the Code, to the full extent the remedies under such provisions are available.

Any material variation or difference in the facts from those set forth in the documents that we have reviewed and upon which we have relied (including, in particular, the Company Representation Letter) may adversely affect the conclusion stated herein.

Opinions

Based upon, subject to, and limited by the assumptions and qualifications set forth herein (including those set forth below), we are of the opinion that:

(1) Host REIT was organized and has operated in conformity with the requirements for qualification and taxation as a real estate investment trust (“REIT”) under the Internal Revenue Code, effective for each of its taxable years ended December 31, 1999, through and including December 31, 2018, and Host REIT’s current organization and current and intended method of operation (as described in the Registration Statement, including the Prospectus, and the Company Representation Letter) will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Internal Revenue Code for taxable year 2019 and thereafter.

(2) The portions of the discussion in the Tax Disclosure that describe applicable U.S. federal income tax law are correct in all material respects as of the date hereof.

April 16, 2019

In addition to the assumptions set forth above, our opinion is subject to the exceptions, limitations and qualifications set forth below:

(1) Host REIT’s ability to qualify as a REIT depends in particular upon whether each .of the Leases is respected as a lease for federal income tax purposes. If one or more Leases are not respected as leases for federal income tax purposes, Host REIT may fail to qualify as a REIT. The determination of whether the Leases are leases for federal income tax purposes is highly dependent on specific facts and circumstances. In addition, for the rents payable under a Lease to qualify as “rents from real property” under the Code, the rental provisions of the Leases and the other terms thereof must conform with normal business practice and not be used as a means to base the rent paid on the income or profits of the lessees. In delivering the opinion set forth above we expressly rely upon, among other things, Host REIT’s representations as to various factual matters with respect to the Leases, including representations as to the commercial reasonableness of the economic and other terms of the Leases at the times the Leases were originally entered into and subsequently renewed or extended (and taking into account for this purpose changes to the economic and other terms of the Leases pursuant to subsequent amendments), the intent and economic expectations of the parties to the Leases, the allocation of various economic risks between the parties to the Leases, taking into account all surrounding facts and circumstances, the conformity of the rental provisions and other terms of the Leases with normal business practice, the conduct of the parties to the Leases, and the conclusion that, except in connection with the Harbor Beach Lease and any other leases that Host REIT acknowledges will not qualify as producing “rents from real property” under the Code, such terms are not being, and will not be, used as a means to base the rent paid on the income or profits of the Lessees. We express no opinion as to any of the economic terms of the Leases, the commercial reasonableness thereof, or whether the actual economic relationships created thereby are such that the Leases will be respected for federal income tax purposes or whether the rental and other terms of the Leases conform with normal business practice (and are not being used as a means to base the rent paid on the income or profits of the Lessees).

(2) Host REIT’s qualification and taxation as a REIT depend upon Host REIT’s ability to meet on an ongoing basis (through actual annual operating results, distribution levels, diversity of share ownership and otherwise) the various REIT qualification tests imposed under the Code, which are described in the Tax Disclosure, and upon Host REIT utilizing all appropriate “savings provisions” (including, without limitation, the provisions of Sections 856(c)(6), 856(c)(7), and 856(g) of the Code, and the provision included in Section 856(c)(4) of the Code (flush language) allowing for the disposal of assets within 30 days after the close of a calendar quarter, and all available deficiency dividend procedures) available to a REIT under the Code in order to correct any violations of the applicable REIT qualification requirements of Sections 856 and 857 of the Code, to the full extent the remedies under such provisions are available. Our opinion set forth above does not foreclose the possibility that Host REIT may have to pay an excise or penalty tax (which tax could be significant in amount) in order to maintain its REIT qualification. We have relied upon the representations and statements of Host REIT and Host LP as to these matters that are set forth or described in the Reviewed Documents and the Company Representation Letter, or incorporated by reference in the Registration Statement, and we have assumed that the information presented in such documents or otherwise furnished to us is accurate and complete in all material respects. We will not review Host REIT’s compliance

April 16, 2019

with these requirements on a continuing basis. Accordingly, no assurance can be given that the actual results of Host REIT’s operations, the sources of its income, the nature of its assets, the level of its distributions to shareholders and the diversity of its share ownership for any given taxable year will satisfy the requirements under the Code for qualification and taxation as a REIT.

(3) Our opinion represents and is based upon our best judgment regarding the application of relevant current provisions of the Code and Treasury Regulations and interpretations of the foregoing as expressed in existing court decisions, legislative history, administrative determinations (including the practices and procedures of the Internal Revenue Service (the “IRS”) in issuing private letter rulings, which are not binding on the IRS except with respect to the taxpayer that receives such a ruling) and published rulings and procedures, as of the date hereof. These provisions and interpretations are subject to changes (which may apply retroactively) that might result in material modifications of our opinion. Our opinion does not foreclose the possibility of a contrary determination by the IRS or a court of competent jurisdiction, or of a contrary position by the IRS or the Treasury Department in regulations or rulings issued in the future. In this regard, an opinion of counsel with respect to an issue represents counsel’s best professional judgment with respect to the outcome on the merits with respect to such issue, if such issue were to be litigated, but an opinion is not binding on the IRS or the courts, and is not a guarantee that the IRS will not assert a contrary position with respect to such issue or that a court will not sustain such a position asserted by the IRS. Host REIT has not requested a ruling from the IRS (and no ruling will be sought) as to the federal tax consequences addressed in this opinion. Furthermore, no assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, would not adversely affect the accuracy of the opinion expressed herein. We undertake no responsibility to advise you of any new developments in the law or in the application or interpretation of the federal income tax laws.

(4) Our opinion letter addresses only the specific tax opinion set forth above, as limited and qualified herein. This opinion letter does not address any other federal, state, local or foreign tax issues.

(5) Our opinion set forth herein is based upon the representations and statements of Host REIT and Host LP as to factual matters that are set forth or described in the Reviewed Documents and the Company Representation Letter, or incorporated by reference in the Registration Statement. In the event any one of the statements, representations, or assumptions upon which we have relied to issue our opinion is incorrect, our opinion might be adversely affected and may not be relied upon.

For a discussion relating the law to the facts, and the legal analysis underlying the opinions set forth in this letter, we incorporate by reference the Tax Disclosure.

This opinion letter has been prepared in connection with the filing of the Registration Statement and speaks as of the date hereof. We assume no obligation by reason of this opinion letter to advise you of any changes in either of our opinions subsequent to the delivery of this opinion letter. Except as provided in the last paragraph, this opinion letter may not be distributed, quoted in whole or in part or otherwise reproduced in any document, or filed with any governmental agency without our express written consent.
