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 instruments, documents, certificates and records we have reviewed; and (iv) the legal capacity of all natural persons. As to any facts material to the opinions expressed herein that were not independently established or verified, we have relied upon oral or written statements and representations of officers and other representatives of the Company. In making our examination of documents executed or to be executed, we have assumed that the counterparties thereto, excluding the Company, have been duly organized and are, and will continue to be, validly existing and in good standing, and have or will have the requisite legal status and legal capacity under the laws of their respective jurisdictions of incorporation or organization and had or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and execution and delivery by such parties of such documents and, except as expressly set forth in the paragraphs below, the validity and binding effect thereof on such parties. In connection with the opinions expressed below, we have assumed that, at or prior to the time of the delivery of any Securities, that (i) the Board of Directors of the Company (or a duly authorized committee thereof) (the “Board”) shall have duly established the terms of the Securities and duly authorized the issuance and sale of such Securities and such authorization shall not have been modified or rescinded; (ii) the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective under the Securities Act; (iii) a prospectus supplement will have been filed with the Commission describing the Securities offered thereby; (iv) the Securities will be issued and sold in compliance with applicable U.S. federal and state securities laws and in the manner stated in the Registration Statement and the applicable prospectus supplement; (v) a definitive purchase, underwriting or similar agreement with respect to any Securities offered will have been duly authorized and validly executed and delivered by the Company and the other parties thereto; (vi) any Securities issuable upon conversion, exchange, redemption or exercise of any Securities being offered will be duly authorized, created and, if appropriate, reserved for issuance upon such conversion, exchange, redemption or exercise; (vii) that the applicable Rights Agreement has been duly authorized, executed and delivered by the Rights Agent and that the members of the Board have acted in a manner consistent with their fiduciary duties as required under applicable law in adopting such Rights Agreement; and (viii) there shall not have occurred any change in law affecting the validity or enforceability of such Securities. We have also assumed that none of the terms of any Securities to be established subsequent to the date hereof, the issuance and delivery of such Securities or the compliance by the Company with the terms of such Securities will violate any applicable law or public policy or will result in a violation of any provision of any instrument or agreement then binding upon the Company, or any restriction imposed by any court or governmental body having jurisdiction over the Company.

Based upon the foregoing, we advise you that, in our opinion:

1. When the necessary corporate action on the part of the Company has been taken to authorize the issuance and sale of shares of Common Stock or the issuance and sale of Securities convertible or exchangeable into or exercisable for shares of Common Stock (each, a “Common Offered Security”), in either case, proposed to be sold by the Company, and when such shares of Common Stock are issued and delivered in accordance with the applicable underwriting or other agreement against payment therefor (in an amount not less than the par value of the Common Stock) or upon conversion, exchange or exercise of any such Common Offered Security, in accordance with the terms of such Common Offered Security or the instrument governing such Common Offered Security providing for such conversion, exchange or exercise as approved by the Board, for the consideration approved by the Board (which consideration is not less than the par value of the Common Stock), in each case, such shares of Common Stock will be validly issued, fully paid and non-assessable.

The opinion in paragraph 1 above is limited to the laws of the State of Delaware that, in our experience, are normally applicable to the shares of Common Stock covered 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. The opinions in paragraphs 2, 3, 4, and 5 above are limited to the laws of the State of New York that, in our experience, are normally applicable to debt securities, purchase contracts, units and warrant transactions of the type covered 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. We have assumed that the choice of New York law to govern the Debt Securities and the Indenture and any supplemental indenture thereto is a valid and legal provision. We have also assumed that New York law will be chosen to govern any Purchase Contract Agreement, any Unit Agreement and any Warrant Agreement. We do not express any opinion with respect to any other law of any other jurisdiction or as to the effect of any such law on the opinions stated herein.

Our opinion that any document is legal, valid and binding is qualified as to:

(a) limitations imposed by bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance, moratorium or other laws relating to or affecting the rights of creditors generally;

(b) rights to indemnification and contribution, which may be limited by applicable law or equitable principles; and

(c) general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief and limitation of rights of acceleration, regardless of whether such enforceability is considered in a proceeding in equity or at law.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement referred to above and further consent to the reference to our name under the caption “Legal Matters” in the prospectus, which is a part of the Registration Statement. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.

Very truly yours,
