Ladies and Gentlemen:

     We have been requested, as your special tax counsel, to render federal tax
advice in connection with the (i) Registration Statement on Form S-3 (File No.
333-55904) (the "Registration Statement") filed by Dominion Resources, Inc. (the
"Company") with the Securities and Exchange Commission for the purpose of
registering under the Securities Act of 1933, as amended (the "Securities Act"),
the Company's Senior Debt Securities, Junior Subordinated Debentures, Trust
Preferred Securities and Related Guarantee, Common Stock, Preferred Stock, Stock
Purchase Contracts and Stock Purchase Units, from the sale of which the Company
may receive proceeds of up to $2,000,000,000, to be offered from time to time by
the Company on terms to be determined at the time of the offering and (ii) the
issuance by the Company of up to 6,600,000 Upper DECS Equity Income Securities
("Equity Income Securities") consisting of up to 6,600,000 Corporate Units, as
described in the Company's Prospectus, dated March 2, 2001 (the "Prospectus"),
which is a part of the Registration Statement, and Prospectus Supplement, dated
March 13, 2002 (the "Prospectus Supplement"). Capitalized terms used and not
defined herein shall have the meanings assigned to them in the Prospectus
Supplement.

     We have reviewed the discussion set forth in the Prospectus Supplement
under the heading "United States Federal Income Tax Consequences" and hereby
advise you that, we are of the opinion that under current United States federal
income tax law, although such discussion does not purport to discuss all
possible United States federal income tax consequences of the Equity Income
Securities, such discussion constitutes an accurate summary of the matters
discussed therein in all material respects.

     We hereby consent to the filing of this opinion as an exhibit to the
Company's Current Report on Form 8-K and the incorporation of this opinion by
reference in the Registration Statement and to references to us under the
heading "Legal Opinions" in the Prospectus Supplement and under the heading
"Legal Opinions" in the Prospectus. We do not admit by giving this consent that
we are in the category of persons whose consent is required under Section 7 of
the Securities Act.


                                        Very truly yours,

                                        /s/ McGuireWoods LLP
