Re:      Range Resources Corporation, a Delaware corporation (the "Company")

Ladies and Gentlemen:

         We have acted as counsel for the Company in connection with the
Company's registration under the Securities Act of 1933 (the "Act") of 2,750,000
shares (the "Shares") of common stock, par value $0.01 per share, of the Company
newly authorized for offer and sale from time to time under the Amended and
Restated 1999 Stock Option Plan (the "Option Plan") under the Company's
registration statement on Form S-8 (the "Registration Statement") filed with the
Securities and Exchange Commission (the "Commission") on June 6, 2003.

         In reaching the opinions set forth herein, we have examined and are
familiar with originals or copies, certified or otherwise identified to our
satisfaction, of such documents and records of the Company and such statutes,
regulations and other instruments as we deemed necessary or advisable for
purposes of this opinion, including (i) the Registration Statement, (ii) the
Certificate of Incorporation of the Company, as filed with the Secretary of
State of the State of Delaware, (iii) the By-laws of the Company, (iv) certain
minutes of meetings of, and resolutions adopted by, the Board of Directors of
the Company and the Company's stockholders authorizing the issuance and offering
of the Shares in the Option Plan and (v) the Option Plan.

         We have assumed that (i) all information contained in all documents we
reviewed is true, correct and complete, (ii) all signatures on all documents we
reviewed are genuine, (iii) all documents submitted to us as originals are true
and complete, (iv) all documents submitted to us as copies are true and complete
copies of the originals thereof, (v) all persons executing and delivering the
documents we examined were competent to execute and deliver such documents and
(vi) the full consideration for each Share, as set forth in the Option Plan,
shall be paid to the Company and in no event shall be less than the par value of
such Share.

         Based on the foregoing, and having due regard for the legal
considerations we deem relevant, we are of the opinion that the Shares, when
offered and issued by the Company pursuant to the terms of the Option Plan, will
be legally issued, fully paid and non-assessable.

         This opinion is limited in all respects to the Delaware General
Corporation Law and the federal laws of the United States of America.








         This opinion letter may be filed as an exhibit to the Registration
Statement. In giving this consent, we do not thereby admit that we come within
the category of person whose consent is required under Section 7 of the Act or
the rules and regulations of the Commission promulgated thereunder.

                                                      Sincerely,



                                                      /s/ VINSON & ELKINS L.L.P.
