This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related applicable Prospectus Supplement, other than as expressly stated herein with respect to the issue of the Securities.

As counsel for the Company and the Operating Partnership, we have examined originals or copies, certified or otherwise identified to our satisfaction, of the Registration Statement, including the Base Prospectus and the Company’s articles of incorporation and bylaws, each as amended to date, the certificate of domestic limited partnership and the Third Amended and Restated Limited Partnership Agreement of the Operating Partnership, each as amended to date, minutes and records of the corporate proceedings of the Company relating to the filing of the Registration Statement and the issuance of the Securities, as provided to us by the Company, and certificates of public officials and of representatives of the Company, and such other instruments and documents as we have deemed necessary or appropriate, as a basis for the opinions hereinafter expressed.

In our examination, we have assumed: (i) the authenticity of original documents and the genuineness of all signatures; (ii) the conformity to the originals of all documents submitted to us as copies; (iii) the truth, accuracy and completeness of the information, representations and warranties contained in the agreements, instruments, documents, certificates and records that we have reviewed; and (iv) the legal capacity of all natural persons. As to all matters of fact, we have relied on the representations and statements of fact made in the documents so reviewed, and we have not independently established or verified the facts so relied on. This opinion is given, and all statements herein are made, in the context of the foregoing.

For purposes of this opinion, we have assumed that certain terms of the Securities to be issued by the Company from time to time will be authorized and approved by the Board of Directors of the Company (the “Board”) or a duly authorized committee thereof (a “Board Committee”) in accordance with North Carolina law, the articles of incorporation and bylaws of the Company, each as amended to date and as the same may be further amended hereafter, the certificate of domestic limited partnership and the Third Amended and Restated Limited Partnership Agreement of the Operating Partnership, each as amended to date and as the same may be further amended hereafter, prior to the issuance thereof. We have also assumed that (i) the Registration Statement and any amendments thereto (including post-effective amendments) have become effective and will continue to be effective at the time of the sale of any Securities covered thereby; (ii) any necessary Prospectus Supplement will have been prepared and filed with the Commission describing any Securities offered thereby; (iii) all Securities will be sold in the manner stated in the Registration Statement and any applicable Prospectus Supplement; and (iv) Securities will not be issued or transferred in violation of restrictions on ownership and transfer set forth in the Company’s articles of incorporation, as amended to date.

This opinion is based as to matters of law solely on (i) applicable provisions of the North Carolina Business Corporation Act and the North Carolina Revised Uniform Limited Partnership Act, in each case, excluding local laws of such jurisdiction (i.e., the statues and ordinances, the administrative decisions and the rules and regulations of counties, towns, municipalities and special political subdivisions of, or authorities or quasi-governmental bodies constituted under the laws of, such jurisdictions and judicial decisions to the extent they deal with any of the foregoing) and (ii) applicable provisions of the laws of the State of New York. As used herein, the term “the laws of the State of New York” include the statutory provisions contained therein, all applicable provisions of the New York Constitution and reported judicial decisions interpreting these laws. We express no opinion herein as to any other state or local laws, statutes, ordinances, rules or regulations.

Our opinions are subject to: (i) the effect of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) (a) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), (b) concepts of materiality, reasonableness, good faith and fair dealing, and (c) the discretion of the court before which a proceeding is brought; and (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy. We express no opinion as to (a) any provision for liquidated damages, default interest, late charges, monetary penalties, make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies, or judicial relief, (c) waivers of rights or defenses contained in Section 514 of the Senior Indenture and Section 514 of the Subordinated Indenture, (d) any provision requiring the payment of attorneys’ fees, where such payment is contrary to law or public policy, (e) any provision permitting, upon acceleration of any Debt Securities, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon, (f) the creation, validity, attachment, perfection, or priority of any lien or security interest, (g) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights, (h) waivers of broadly or vaguely stated rights, (i) covenants not to compete, (j) provisions for exclusivity, election or cumulation of rights or remedies, (k) provisions authorizing or validating conclusive or discretionary determinations, (l) grants of setoff rights, (m) proxies, powers and trusts, (n) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property, (o) provisions purporting to make a guarantor primarily liable rather than as a surety, (p) provisions purporting to waive modifications of any guaranteed obligation to the extent such modification constitutes a novation, (q) any provision to the extent it requires that a claim with respect to a security denominated in other than U.S. dollars (or a judgment in respect of such a claim) be converted into U.S. dollars at a rate of exchange at a particular date, to the extent applicable law otherwise provides and (r) the severability, if invalid, of provisions to the foregoing effect.

We have assumed (a) that each of the Debt Securities, Guarantees, Depositary Shares and Warrants, and the respective indentures, deposit agreements and warrant agreements governing such securities and any related Board resolution, supplemental indenture or officers’ certificate establishing the terms thereof (collectively, the “Documents”) will be governed by the internal laws of the State of New York, (b) that each of the Documents has been or will be duly authorized, executed and delivered by the parties thereto, (c) that each of the Documents constitutes or will constitute legally valid and binding obligations of the parties thereto other than the Company and the Operating Partnership, enforceable against each of them in accordance with their respective terms, and (d) that the status of each of the Documents as legally valid and binding obligations of the parties will not be affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders or (iii) failures to obtain required consents, approvals or authorizations from, or to make required registrations, declarations or filings with, governmental authorities.
