Re: Registration Statement on Form S-3

Ladies and Gentlemen:

     We have acted as counsel for Range Resources Corporation, a Delaware corporation (the “Company”), with respect to certain legal matters in connection with the registration by the Company under the Securities Act of 1933 (the “Securities Act”) of the offer and sale by the Company from time to time pursuant to Rule 415 under the Securities Act of shares of common stock, par value $0.01 per share (the “Common Stock”). The Company has advised us that the Common Stock will be offered in amounts, at prices and on terms to be determined in light of market conditions at the time of sale and to be set forth in a prospectus supplement to the prospectus contained in the Company’s automatic shelf registration statement on Form S-3 to which this opinion is to be filed as an exhibit (the “Registration Statement”). The Registration Statement will be filed with the Securities and Exchange Commission (the “Commission”) on the date hereof.

     Before rendering the opinion hereinafter set forth, we examined, among other things, the Registration Statement, the Restated Certificate of Incorporation, as amended, and Amended and Restated By-laws of the Company, each as in effect on the date hereof resolutions of the Company’s Board of Directors (the “Board”), and originals or photostatic or certified copies of all those corporate records of the Company and of all those agreements, communications and other instruments, certificates of public officials, certificates of corporate officials and such other documents as we have deemed relevant and necessary as a basis for the opinion hereinafter set forth. As to factual matters, with respect to information that is in the possession of the Company relevant to the opinion herein stated, we have relied without investigation, to the extent we deem such reliance proper, upon certificates or representations made by the Company’s duly authorized representatives.

     Based on the foregoing examination and review and having due regard for the legal considerations we deem relevant, we are of the opinion that, when (i) the Board has taken all necessary corporate action to approve the issuance and terms of the offering thereof and related matters; and (ii) certificates representing the shares of Common Stock have been duly executed, countersigned, registered and delivered in accordance with the applicable definitive purchase, underwriting or similar agreement approved by the Board, then upon payment of the consideration therefor (not less than the par value of the Common Stock) provided for therein and for the consideration approved by the Board (not less than the par value of the Common Stock), such shares of Common Stock will be legally issued, fully paid and non-assessable.

     The foregoing opinion is limited to the laws of the United States of America and to the Delaware General Corporation Law as in effect on the date hereof and we undertake no duty to update or supplement the foregoing opinion to reflect any facts or circumstances that may hereafter come to our attention or to reflect any changes in any law that may hereafter occur or become effective. The Common Stock may be offered from time to time on a delayed or continuous basis, and this opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect.
