For purposes of our opinion in paragraph number (iii) below regarding the good standing of the Guarantor, we have relied solely and exclusively upon a certificate issued by West Virginia public officials, and such opinion is not intended to provide or state any conclusion or assurance beyond that conveyed in such certificate.

We are opining herein only as to the effect on the subject transaction of the laws of the State of West Virginia with respect to the Guarantor; and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or as to any matters of federal law, municipal law, or the laws of any local agencies within any state. We herein express no opinion with respect to any issues or matters addressed or stated in those letters of other counsel; and, to the extent elements of those opinions are necessary to the opinions expressed herein we have, with your consent, relied upon and assumed the correctness of such elements of those opinions.

Our knowledge of all matters connected herewith is limited to the actual knowledge of the lawyers of the firm who have participated in our limited representation of the Guarantor, respectively, in connection with the opinions expressed herein and the transactions contemplated thereby, solely gained through the performance of such representation after consultation with such other attorneys in the firm and review of such documents in our possession as such lawyers considered appropriate. Except as expressly set forth herein, we have not undertaken any independent investigation (including, without limitation, conducting any review, search, or investigation of any public files or records or dockets) to determine the existence or absence of any such facts. This opinion deals only with the specific legal issues that it explicitly addresses, and no opinions shall be implied as to matters not so addressed.

Further, we have assumed, with your express consent, the due authorization of all documents connected with the Principal Documents (as defined below) and all other documents contemplated by the transactions connected therewith by all parties thereto other than the Guarantor, the due execution and delivery of the Principal Documents by all parties thereto other than the Guarantor, and that the Principal Documents constitute legal, valid and binding obligations of all parties thereto, enforceable against them in accordance with their terms.

In rendering our opinions herein, we have relied with respect to factual matters, upon the Officers’ Certificate (defined below). In addition thereto, we have reviewed and relied upon such records, documents, certificates and other instruments as in our judgment are necessary or appropriate to form the basis for rendering our opinions, including, without limitation, the following:

(ii) the certificate with respect to various factual matters signed by an officer of the Guarantor and dated the date of this opinion (the “Officers’ Certificate”);

(x) the prospectus containing the Registration Statement (the “Prospectus”).

Items (iv) through (x) as set forth above shall hereinafter collectively be referred to as the “Principal Documents”.

Subject to the assumptions, exceptions and limitations hereinabove and hereinafter stated, it is our opinion that:
