Ladies and Gentlemen:

We have acted as Pennsylvania corporate counsel to Gaming and Leisure Properties, Inc., a Pennsylvania corporation (the “Company”), and as Pennsylvania limited partnership counsel to GLP Capital, L.P., a Pennsylvania limited partnership of which the Company is the general partner (the “Operating Partnership”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-3, dated the date hereof (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”), relating to the issuance and sale from time to time of (i) shares of common stock, par value $0.01 per share of the Company (the “Common Stock”), (ii) shares of preferred stock, par value $0.01 per share of the Company (the “Preferred Stock”), (iii) depositary shares representing interests in Preferred Stock (the “Depositary Shares”) evidenced by depositary receipts issued against the deposit of shares of Preferred Stock pursuant to a deposit agreement to be entered into between the Company and a bank or trust company selected by the Company, (iv) debt securities (the “Debt Securities”) of the Operating Partnership and GLP Financing II, Inc., a Delaware corporation and a wholly owned subsidiary of the Operating Partnership (“Capital Corp.”), and (v) guarantees of the Debt Securities by the Company (the “Guarantees”). Each of the Common Stock, the Preferred Stock, the Depositary Shares, the Debt Securities and the Guarantees are individually referred to in this opinion letter as a “Security” and are collectively referred to as the “Securities.” You have requested our opinion letter with respect to the matters set forth below.

As your Pennsylvania counsel, we have examined all such documents that we have considered necessary in order to enable us to render this opinion letter, including, but not limited to, (i) the Registration Statement and the related form of prospectus included therein (the “Prospectus”), in substantially the form filed with the Commission pursuant to the Securities Act; (ii) the Company’s Articles of Incorporation, as amended (the “Articles”); (iii) the Company’s Bylaws, as amended (the “Bylaws”); (vi) the Operating Partnership’s Certificate of Limited Partnership (the “Certificate of Limited Partnership”); (v) the Operating Partnership’s Agreement of Limited Partnership, as amended (the “Partnership Agreement”); (vi) certain resolutions adopted by the Board of Directors of the Company (the “Board”) in connection with the Registration Statement (the “Board Resolutions”); (vii) certain corporate records and instruments; and (viii) such laws and regulations as we have deemed necessary for the purposes of rendering the opinions set forth herein.

In our examination, we have assumed: (1) the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of and conformity to originals of such documents that have been presented to us as duplicates or certified or conformed copies, and the accuracy, completeness and authenticity of originals; (2) the due execution and delivery of all documents (except that no such assumption is made as to the Company or the
