The Primary Securities and the Resale Securities are hereinafter referred to, collectively, as the securities (the “Securities”).

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S- K under the Securities Act.

In connection with the preparation of the Registration Statement and this opinion letter, we have examined, considered and relied upon the following documents (collectively, the “Documents”):

(i) the Company’s amended and restated certificate of incorporation as filed with the Secretary of State of the State of Delaware (the “Secretary of State”);

(ii) the Company’s amended and restated by-laws;

(iii) certain resolutions adopted by the board of directors of the Company (the “Board”) with respect to the Registration Statement;

(iv) the Registration Statement, including the prospectus contained therein, and exhibits thereto;

(v) the form of Indenture included as an exhibit to the Registration Statement (as such indenture may be supplemented from time to time (the “Indenture”)); and

(vi) such corporate records of the Company, certificates of public officials, officers of the Company and other persons, and other documents, agreements and instruments, as we have deemed necessary as a basis for the opinions expressed below.

For purposes of this opinion, we have not reviewed any documents other than the Documents. We have assumed that there exists no provision in any document relating to the matters covered by this opinion that we have not reviewed that is inconsistent with the Documents or the opinions stated herein. We have conducted no independent factual investigation of our own but rather have relied solely upon the Documents, the statements and information set forth therein and the additional matters recited or assumed herein, all of which we have assumed to be true, complete and accurate in all material respects. In rendering the opinions set forth below, we have assumed without investigation (i) the genuineness of all signatures on the Documents; (ii) the legal capacity under all applicable laws and regulations of all natural persons signing each of the Documents as or on behalf of the parties thereto; (iii) the authenticity of all Documents submitted to us as originals; (iv) the conformity to authentic original documents of all Documents submitted to us as copies; and (v) that the Documents, in the forms submitted to us for our review, have not been and will not be, altered or amended in any respect material to our opinion as set forth herein.
