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.

For purposes of the opinion expressed below, we have assumed (i) the authenticity of all documents submitted to us as originals, (ii) the conformity to the originals of all documents submitted as certified or photostatic copies and the authenticity of the originals thereof, (iii) the legal capacity of natural persons, (iv) the genuineness of all signatures and (v) the due authorization, execution and delivery of all documents by all parties and the validity and binding effect and enforceability thereof upon the Company.

Based upon the foregoing, and having regard for such legal considerations as we have considered necessary for purposes hereof, we are of the opinion that:

the Company is a corporation validly existing and in good standing under the laws of the Commonwealth of Virginia, and has the requisite corporate power to issue the Notes; and

the Notes are in the form contemplated by the Indenture, have been duly authorized by the Company for issuance and sale pursuant to the Terms Agreement and, when authenticated by the Trustee in accordance with the Indenture (assuming the due authorization, execution and delivery of the Indenture by the Trustee) and delivered by the Company in accordance with the terms of the Terms Agreement against payment therefor in accordance with the Resolutions and the terms of the Terms Agreement, will constitute valid and binding obligations of the Company under New York law, enforceable against the Company under New York law in accordance with their terms, and will be entitled to the benefits of the Indenture.

The opinion in paragraph 1 with respect to incorporation, existence and good standing of the Company is based solely on the Good Standing Certificate.

Our opinion in paragraph 2 is subject to the following additional assumptions and qualifications:

(a) Enforceability is subject to, and may be limited by: (i) bankruptcy, insolvency, reorganization, arrangement, moratorium and other similar laws affecting creditors’ rights generally, including, without limitation, laws regarding fraudulent conveyances and preferential transfers; (ii) general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief (regardless of whether considered in a proceeding at law or in equity); (iii) any statute, decision or rule of law prohibiting or limiting the exercise of simultaneous remedies; and (iv) limitations or qualifications on the enforcement of certain rights, remedies, waivers and other provisions by the jurisdiction in which enforcement thereof is sought.

(b) Further, we express no opinion on any provision contained in the Indenture or the Notes (i) relating to indemnification or contribution which are violative of the public policy underlying any law, rule or regulation (including any federal or state securities law, rule or regulation), or that purports to release, exculpate or exempt a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves gross negligence, recklessness, willful misconduct or unlawful conduct; (ii) purporting to require a party thereto to pay or reimburse attorneys’ fees incurred by another party, or to indemnify another party therefor, which provisions may be limited by applicable statutes and decisions relating to the collection and award of attorneys’ fees; (iii) relating to consents to or restrictions upon governing law; (iv) regarding consent to service, jurisdiction, venue or forum of any claim, demand, action or cause of action arising under or related to the Indenture, the Notes or the transactions contemplated therein, which may not be binding on the courts in the forums selected or excluded; (v) purporting to waive certain rights or defenses, including the waiver by any party of the right to trial by jury, to the extent that such a waiver is deemed to violate public policy; (vi) that requires waiver or amendments to be made only in writing, or (vii) regarding the severability, if invalid, of provisions of such agreements.

We express no opinion as to the laws of any state or jurisdiction other than (i) the internal laws of the State of New York and the Commonwealth of Virginia (excluding those of counties, cities and other municipalities), and (ii) the federal laws of the United States, which, in the case of each of the laws referred to in clauses (i) and (ii), in the experience of our attorneys who are members of the bar in New York and Virginia and who are experienced in transactions of the type contemplated Indenture and the Notes are normally applicable to the such transactions, but without our having made any special investigation concerning any other law, rule or regulation, in each case in effect on the date hereof.

This opinion is being furnished to you for submission to the Commission as an exhibit to the Company’s Current Report on Form 8-K, which is incorporated by reference in the Registration Statement in accordance with the requirements of Form S-3 and the rules and regulations promulgated under the Securities Act. We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement with the Commission on the date hereof and to the use of the name of our firm in the section entitled “Legal Matters” in the Prospectus. In giving this consent, we do not admit that we are within the category of persons whose consent is required by Section 7 of the Securities Act or the rules and regulations promulgated thereunder by the Commission.
