Commitment Letter

Pinnacle Entertainment, Inc. (the “Company”) has received a commitment letter dated November 17, 2015 (the “Commitment Letter”) from JPMorgan Chase Bank, N.A., J.P. Morgan Securities LLC, Bank of America, N.A., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Goldman Sachs Bank USA, Fifth Third Bank, U.S. Bank National Association, Credit Agricole Corporate and Investment Bank, Deutsche Bank AG New York Branch, Deutsche Bank Securities Inc., Wells Fargo Bank, National Association and Wells Fargo Securities, LLC (collectively, the “Commitment Parties”) to provide a portion of the debt financing required by the Company to consummate the transactions contemplated by the previously announced Agreement and Plan of Merger (the “Merger Agreement”) with Gaming and Leisure Properties, Inc., a Pennsylvania corporation (“Parent”), and Gold Merger Sub, LLC, a Delaware limited liability company and a wholly owned subsidiary of Parent (“Merger Sub”), including (i) the merger of Merger Sub with and into the Company (the “Merger”), with Merger Sub surviving the Merger as a wholly owned subsidiary of Parent and (ii) the separation by the Company of its operating assets (and certain real estate assets) and liabilities into a newly formed subsidiary (“OpCo”) and, immediately prior to the closing of the Merger, the distribution to its stockholders, on a pro rata basis, of all of the issued and outstanding shares of common stock of OpCo (such distribution referred to as the “Spin-Off” and the transactions described in this paragraph and those contemplated thereby referred to, collectively, as the “Transactions”).

The Commitment Parties have committed to provide financing in an aggregate principal amount of $585 million to OpCo, comprised of a (i) $185 million senior secured term loan A facility (the “Term Loan A Facility”) and (ii) $400 million senior secured revolving credit facility (the “Revolving Credit Facility”, and together with the Term Loan A Facility, collectively, the “Committed Facilities”). The Commitment Parties have also agreed to use their commercially reasonable efforts to syndicate a $350 million senior secured term loan B facility, which may, at the election of OpCo, be increased or decreased by up to $125 million in connection with the issuance of senior unsecured notes to finance a portion of the Transactions, as further described in the Commitment Letter (the “Term Loan B Facility”, and together with the Committed Facilities, collectively, the “Facilities”). The Term Loan A Facility and the Revolving Credit Facility would mature on the fifth anniversary of the borrowings under the Term Loan A Facility, and the Term Loan B Facility would mature on seventh anniversary (or the sixth anniversary, if OpCo so elects) of the borrowings under the Term Loan B Facility. The interest rates on the Facilities would be based on customary market LIBOR or base rates plus an applicable margin. The obligations of OpCo and the guarantors under the Facilities would be secured by substantially all assets of OpCo and the guarantors, subject to certain exceptions.

As noted in the Commitment Letter, it is anticipated that OpCo will issue senior unsecured notes (the “Notes”) in an aggregate principal amount of $300 million to provide a portion of the debt financing required by the Company to consummate the Transactions. The principal amount of the Notes may, at the election of OpCo, be increased or decreased by up to $125 million, as further described in, and in accordance with the terms of, the Commitment Letter.

Funding of the Facilities is subject to certain customary conditions, including, but not limited to, receipt of financial information, delivery of customary documentation relating to OpCo and its subsidiaries and consummation of the Spin-Off.

The foregoing description of the Commitment Letter does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Commitment Letter, which is attached to this Current Report on Form 8-K as Exhibit 10.1 and is incorporated by reference.

Amendment and Restatement of Commitment Letter Dated July 20, 2015

The Company has received an amended and restated commitment letter dated November 17, 2015 (the “A&R Bridge Commitment Letter”) from JPMorgan Chase Bank, N.A., J.P. Morgan Securities LLC, Bank of America, N.A., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Goldman Sachs Bank USA, Fifth Third Bank, U.S. Bank National Association, Credit Agricole Corporate and Investment Bank, Deutsche Bank AG New York Branch, Deutsche Bank AG Cayman Islands Branch, Deutsche Bank Securities Inc., Wells Fargo Bank, National Association and Wells Fargo Securities, LLC (collectively, the “A&R Bridge Commitment Parties”), which amends and restates the previously disclosed commitment letter dated July 20, 2015 from the A&R Bridge Commitment Parties, pursuant to which the A&R Bridge Commitment Parties commit to provide financing in an aggregate principal amount of $1.1 billion to fund the Company’s obligations in connection with the Transactions comprised of a (i) $900 million senior secured term loan bridge facility and (ii) $200 million senior secured revolving credit facility.

The A&R Bridge Commitment Letter provides, among other things, that OpCo, and not a wholly-owned subsidiary of OpCo, will obtain financing as the borrower pursuant to, and subject to the terms and conditions of, the A&R Bridge Commitment Letter.

                The foregoing description of the A&R Bridge Commitment Letter does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the A&R Bridge Commitment Letter, which is attached to this Current Report on Form 8-K as Exhibit 10.2 and is incorporated by reference.

                The commitments provided in the Commitment Letter (the “Takeout Commitments”) and the commitments provided in the A&R Bridge Commitment Letter (the “Bridge Commitments” and, together with the Takeout Commitments, the “Commitments”) are alternative Commitments and (i) if the Takeout Commitments are funded, the Bridge Commitments will not be funded and will terminate upon the initial funding of the Takeout Commitments and (ii) if the Bridge Commitments are funded, the Takeout Commitments will not be funded and will terminate upon the initial funding of the Bridge Commitments.

From time to time, the Commitment Parties, the A&R Bridge Commitment Parties or their respective affiliates have provided investment banking, general financing and advisory services to Pinnacle and its affiliates in the past and may do so in the future. They received, and expect to receive, customary fees and commissions for these services.
