We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others and such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinions set forth herein.

In our examination, we have assumed the legal capacity and competency of all natural persons, the genuineness of all signatures, including endorsements, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified, conformed or photostatic copies and the authenticity of the originals of such copies. In making our examination of executed documents or documents to be executed, we have assumed (i) that the parties thereto, other than the Company, had or will have the power, corporate or other, to enter into and perform all obligations thereunder and (ii) the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents, and the validity and binding effect thereof on such parties. We have also assumed that each of the Indenture, any supplemental indenture thereto, the Warrant Agreements, Subscription Rights Agreements, Deposit Agreements, Stock Purchase Contracts and the Unit Agreements has been or will be duly authorized, executed and delivered by the Trustee, Warrant Agents, Subscription Agent, Depositaries, Purchase Contract Agents and Unit Agents, as the case may be, and that any Debt Securities, Warrants, Subscription Rights Certificates, Receipts, Purchase Contracts and Units that may be issued will be manually authenticated, signed or countersigned, as the case may be, by duly authorized officers of the applicable Trustee, Warrant Agent, Subscription Agent, Depositary, Purchase Agent and Unit Agent, as the case may be. We have also assumed that the choice of New York law to govern the Indenture and any supplemental indentures thereto is a valid and legal provision. We have also assumed that New York law will be chosen to govern the Warrant Agreements, the Deposit Agreements, the Subscription Rights Agreements, the Purchase Contracts and the Units, and that such choice is a valid and legal provision.

In addition, we have assumed that the terms of the Offered Securities will have been established so as not to, and that the execution and delivery by the Company of, and the performance of its obligations under, the Indenture and any supplemental indenture thereto, the Offered Securities, the Warrant Agreements, Subscription Rights Agreements, Deposit Agreements, Stock Purchase Agreements the Units and the Unit Agreements, will not violate, conflict with or constitute a default under (i) any agreement or instrument to which the Company or its properties is subject, (ii) any law, rule or regulation to which the Company or its properties is

subject, (iii) any judicial, administrative or regulatory order or decree of any governmental authority; or (iv) any consent, approval, license, authorization or validation of, or filing, recording or registration with, any governmental authority.

As to any facts material to the opinions expressed herein which were not independently established or verified, we have relied upon oral or written statements and representations of officers and other representatives of the Company and others.

We do not express any opinion with respect to the laws of any jurisdiction other than (i) the General Corporation Law of the State of Delaware and (ii) the laws, rules and regulations of the State of New York that, in our experience, are normally applicable to transactions of the type contemplated by the Registration Statement and, to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws (all of the foregoing being referred to as “Opined on Law”). We do not express any opinion with respect to the law of any jurisdiction other than Opined on Law or as to the effect of any such non-Opined on Law on the opinions herein stated. The Offered Securities may be issued from time to time on a delayed or continuous basis, and this opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect.
