As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We are opining herein as to the effect on the subject transaction only of the federal laws of the United States and the General Corporation Law of the State of Delaware (the “DGCL”), and we express no opinion with respect to the applicability to the opinions expressed herein, or the effect thereon, of the laws of any other jurisdiction or as to any matters of municipal law or the laws of any local agencies within any state.
Except as otherwise stated herein, our opinions herein are based upon our consideration of only those statutes, rules and regulations that, in our experience, are normally applicable to registered public offerings of common stock. We express no opinion as to any state or federal laws or regulations applicable to the subject transactions because of the legal or regulatory status of any parties to the Warrant Agreements (as defined below) or the legal or regulatory status of any of their affiliates.
Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof:
1. The Primary Preferred Shares and the Resale Preferred Conversion Shares have been duly authorized by all necessary corporate action of the Company and are validly issued, fully paid and nonassessable.
2. The Primary Warrant Shares and the Resale Warrant Shares have been duly authorized by all necessary corporate action of the Company and are validly issued, fully paid and nonassessable.
3. When the Primary CCS Shares shall have been duly registered on the books of the transfer agent and registrar therefor in the name or on behalf of the recipients thereof, and have been issued by the Company against payment therefor (not less than par value) in the circumstances contemplated by the Registration Statement, the issuance of the Primary CCS Shares will have been duly authorized by all necessary corporate action of the Company, and the Primary CCS Shares will be validly issued, fully paid and nonassessable.
4. When the Primary OTB Shares shall have been duly registered on the books of the transfer agent and registrar therefor in the name or on behalf of the recipients thereof, and have been issued by the Company against payment therefor (not less than par value) in the circumstances contemplated by the Registration Statement, the issuance of the Primary OTB Shares will have been duly authorized by all necessary corporate action of the Company, and the Primary OTB Shares will be validly issued, fully paid and nonassessable.

In rendering the foregoing opinions, we have assumed that (i) at or prior to the time of the delivery of any Primary Securities or Resale Securities, as applicable, the Registration Statement will have been declared effective under the Act and that the registration will apply to all of the Primary Securities and Resale Securities, and will not have been modified or rescinded and that there will not have occurred any change in law affecting the validity of the offer, sale or issuance of such Primary Securities and Resale Securities, as applicable, and (ii) the Company will comply with all applicable notice requirements regarding uncertificated shares provided in the DGCL.
Our opinions are subject to: (a) the effects of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights or remedies of creditors; (b) (1) the effects 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), (2) concepts of materiality, reasonableness, good faith and fair dealing, and (3) the discretion of the court before which a proceeding is brought; and (c) the invalidity, under certain circumstances under law or court decisions, of provisions for the indemnification or exculpation of, or contribution to, a party with respect to a liability, where such indemnification, exculpation or contribution is contrary to public policy.
