Item 1.01 Entry Into a Material Definitive Agreement.

On June 11, 2014, Range Resources Corporation (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC, as underwriters party thereto (the “Underwriters”), in connection with an underwritten public offering (the “Offering”) of 4,560,000 shares of common stock (the “Common Shares”). Pursuant to the Underwriting Agreement, the Company granted the Underwriters a 30-day option to purchase up to an additional 684,000 shares of common stock. The Offering is expected to close on June 17, 2014, subject to customary closing conditions.

The issuance and sale of the Common Shares has been registered under the Securities Act of 1933 (the “Securities Act”) pursuant to an automatic shelf Registration Statement on Form S-3 (Registration No. 333-196122) of the Company, filed with and deemed automatically effective by the Securities and Exchange Commission on May 21, 2014, and the prospectus supplement dated June 12, 2014 and filed with the Securities and Exchange Commission on June 13, 2014.

In connection with the Offering, Vinson & Elkins L.L.P. issued an opinion as to the legality of the Common Shares to be sold in the Offering, which opinion is filed as Exhibit 5.1 to this Current Report.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company and customary conditions to closing, obligations of the parties and termination provisions. Additionally, the Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the Underwriters may be required to make because of any of those liabilities. Furthermore, the Company has agreed with the Underwriters not to offer or sell any shares of its common stock (or securities convertible into or exchangeable for common stock), subject to customary exceptions, for a period of 45 days after the date of the Underwriting Agreement without the prior written consent of the Underwriters.

The Underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters or their affiliates may perform various financial advisory, investment banking and commercial banking services from time to time for the Company and its affiliates under the Company’s revolving credit facility.

The foregoing description of the Underwriting Agreement is not complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, a copy of which is filed herewith as Exhibit 1.1 and is incorporated in this Item 1.01 by reference.
