This opinion is being furnished in accordance with the requirements of Item 8 of Form S-8 and Item 601(b)(5)(i) of Regulation S-K.

Based on the foregoing, we are of the opinion that:

(i)the Shares have been duly authorized and, when issued and delivered in accordance with the terms of the DCP, will be validly issued, fully paid, and non-assessable; and

(ii)upon the issuance of the Obligations in the manner contemplated by the Registration Statement and in accordance with the terms of the DCP, such

    In rendering the opinions expressed above, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.
