As to facts material to this opinion letter, we have relied upon certificates, statements or representations of public officials, of officers and representatives of the Company (including the Certificate) and of others, without any independent verification thereof. We have assumed, without investigation, the following: (a) the genuineness of signatures, including electronic signatures, appearing upon agreements, instruments, certifications, documents, and proceedings, (b) that each document submitted to us for review is accurate and complete, each such document that is an original is authentic and each such document that is a copy conforms to an authentic original, (c) the legal capacity of natural persons who are involved on behalf of the Company to enter into and perform the referenced instrument or agreement or to carry out their role in the transactions contemplated thereby, (d) the truth, accuracy and completeness of the information, representations and warranties contained in the documents, instruments, certificates and records we have reviewed, and (e) the absence of any undisclosed modifications to the agreements and instruments reviewed by us.

Based on and subject to the foregoing and to the other assumptions, qualifications and limitations set forth herein, we are of the opinion that all necessary corporate action on the part of the Company has been taken to authorize the issuance of the Resale Shares, and that the Resale Shares are validly issued, fully paid and nonassessable.
