supplemental indentures, collectively, the “Supplemental Indentures,” and the Base Indenture, as amended and supplemented by the Supplemental Indentures, the “Indenture”).

          In connection with our representation of the Companies, and as a basis for the opinion hereinafter set forth, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (hereinafter collectively referred to as the “Documents”):

          1. The Registration Statement and the related form of prospectus included therein (the “Prospectus”) in the form in which it was transmitted to the Commission under the Securities Act;

          2. The Articles of Incorporation of each Company, as amended through the date hereof (the “Articles”), certified by the Commonwealth of Virginia State Corporation Commission (the “Virginia Commission”);

          3. The Bylaws of each Company (the “Bylaws”), certified as of the date hereof by an officer of such Company;

          4. Resolutions adopted by the Board of Directors of each Company, relating to, among other matters, the registration and issuance by such Company of its New Guarantee, certified as of the date hereof by an officer of such Company;

          5. Certificates of the Virginia Commission as to the good standing of the Companies, dated as of a recent date (the “Good Standing Certificates”);

          6. The Indenture;

          7. A certificate executed by an officer of each Company, dated as of the date hereof; and

          8. Such other documents and matters as we have deemed necessary or appropriate to express the opinion set forth below, subject to the assumptions, limitations and qualifications stated herein.

          2. Each individual executing any of the Documents on behalf of a party (other than the Companies) is duly authorized to do so.

          3. Each of the parties (other than the Companies) executing any of the Documents has duly and validly executed and delivered each of the Documents to which such party is a signatory, and the obligations of the parties (other than the Companies) set forth in the Documents are legal, valid, binding and enforceable in accordance with all stated terms.

          4. All Documents submitted to us as originals are authentic. All Documents submitted to us as certified or photostatic copies conform to the original documents. All signatures on all Documents are genuine. All public records reviewed or relied upon by us or on our behalf are true and complete. All representations, warranties, statements and information contained in the Documents are true and complete. There has been no oral or written modification of or amendment to any of the Documents, and there has been no waiver of any provision of any of the Documents, by action or omission of the parties or otherwise.

          Based upon the foregoing and subject to the assumptions, limitations and qualifications stated herein, it is our opinion that:

          1. Each Company is validly existing as a corporation under the laws of the Commonwealth of Virginia and, based solely on the Good Standing Certificates, is in good standing under the laws of the Commonwealth of Virginia.

          2. Each Company had the requisite corporate power and authority to execute and deliver the Supplemental Indenture(s) to which it is a party at the time of such execution and delivery and had and has the requisite corporate power and authority to perform its obligations under the Indenture (including its New Guarantee).

          4. The Supplemental Indenture(s) to which each Company is a party have been duly executed and delivered by such Company.

          5. The execution and delivery by each Company of the Supplemental Indenture(s) to which it is a party and the performance by such Company of its obligations under the Indenture (including its New Guarantee) do not and will not violate the Articles or the Bylaws of such Company.
