We have made such examination of law as we have deemed necessary to express the opinions contained herein. As to matters of fact relevant to this opinion, we have relied upon, and assumed without independent verification, the accuracy of certificates of public officials and officers of the Company. We have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified, facsimile or photostatic copies, and the authenticity of the originals of such copies.

Based upon the foregoing, and subject to the limitations, qualifications, exceptions and assumptions expressed herein, we are of the opinion, assuming no change in the applicable law or pertinent facts, that:

 

1.

The Shares have been duly authorized for issuance and, when the Shares are issued and paid for in accordance with the terms and conditions set forth in the Registration Statement, the Shares will be validly issued, fully paid and non-assessable.

 

2.

The Pre-Funded Warrants and the Warrants, when issued as set forth in the Registration Statement, will have been duly authorized and, upon delivery of the consideration as provided in the Underwriting Agreement, will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, subject, as to enforcement, to bankruptcy, insolvency, fraudulent conveyance, fraudulent transfer, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general equitable principles (regardless of whether enforcement is sought in equity or at law), including, without limitation, principles regarding good faith and fair dealing (including the possible unavailability of specific performance or injunctive relief, concepts of materiality and reasonableness, and the discretion of the court before which a proceeding is brought).

 

3.

The Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants, when issued as set forth in the Registration Statement, will have been duly authorized for issuance and, when the Pre-Funded Warrant Shares are issued upon exercise of the Pre-Funded Warrants in accordance with the terms thereof, the Pre-Funded Warrant Shares will be validly issued, fully paid and non-assessable.

 

4.

The Warrant Shares issuable upon exercise of the Warrants, when issued as set forth in the Registration Statement, will have been duly authorized for issuance and, when the Warrant Shares are issued upon exercise of the Warrants in accordance with the terms thereof, the Warrant Shares will be validly issued, fully paid and non-assessable.

This opinion is limited in all respects to the General Corporation Law of the State of Delaware, and, as to the Pre-Funded Warrants and/or the Warrants constituting valid and legally binding obligations of the Company, with respect to the laws of the State of New York, and we express no opinion as to the laws, statutes, rules or regulations of any other jurisdiction. The reference and limitation to the “General Corporation Law of the State of Delaware” includes all applicable Delaware statutory provisions of law and reported judicial decisions interpreting these laws.

We hereby consent to the filing of this opinion letter in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act as Exhibit 5.1 to the Registration Statement and to the reference to our firm under the caption “Legal Matters” in the Registration Statement and the prospectus contained therein.
