In connection with the opinions expressed above, we have assumed that, at the time of the delivery of any such Security, (i) the Board of Directors of the Company shall have duly established the terms of such Security and duly authorized the issuance and sale of such Security and such authorization shall not have been modified or rescinded; (ii) the Company shall remain in good standing and shall have a legal corporate existence under the laws of the State of Delaware; (iii) the Registration Statement shall have become effective and such effectiveness shall not have been terminated or rescinded; (iv) any indenture and any supplemental indenture to be entered into in connection with the issuance of any Debt Security shall be a valid, binding and enforceable agreement of each party thereto; (v) the number of shares of Common Stock or Preferred Stock, as the case may be, to be offered and sold under the Registration Statement shall not exceed the number of shares of Common Stock or Preferred Stock, as applicable, authorized in the Certificate of Incorporation of the Company; and (vi) there shall not have occurred any change in law affecting the validity or enforceability of such Security. We have also assumed that the execution, delivery and performance by the Company of any Security whose terms are established subsequent to the date hereof (a) require no action by or in respect of, or filing with, any governmental body, agency or official and (b) do not contravene, or constitute a default under, any public policy, any provision of applicable law or regulation or any judgment, injunction, order or decree or any agreement or other instrument binding upon the Company.

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) 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), concepts of materiality, reasonableness, good faith and fair dealing, and 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.

The foregoing opinions are limited to (i) the General Corporation Law of the State of Delaware and (ii) the internal laws of the State of New York. We express no opinion as to the effect of the laws of any other jurisdiction.

We hereby consent to the use of this opinion as an exhibit to the Registration Statement and to the reference to this firm under the heading “Legal Matters” in the related prospectus. We further consent to the incorporation by reference of this letter and consent into any registration statement or post-effective amendment filed pursuant to Rule 462(b) under the Act with respect to the Securities.
