(e)

On May 11, 2010, at the Annual Meeting of Stockholders (the “Annual Meeting”) of Pinnacle Entertainment, Inc. (the “Company”), the stockholders approved an amendment (the “Amendment to the 2005 Plan”) to the Company’s 2005 Equity and Performance Incentive Plan (the “2005 Plan”).

The Amendment to the 2005 Plan increases by 1,100,000 the maximum number of shares of the Company’s common stock that may be issued or subject to awards under the 2005 Plan. The Amendment to the 2005 Plan also increases the maximum number of awards under the 2005 Plan that may be issued as incentive stock options from 4,750,000 shares to 5,850,000 shares and increases the 2005 Plan by certain non-plan option grants to the extent that such non-plan options are forfeited, expire or are terminated without issuance of shares, or are settled for cash or otherwise do not result in the issuance of shares. Following the Amendment to the 2005 Plan, up to an aggregate of 5,850,000 shares of common stock of the Company, plus certain shares subject to awards granted under specified prior plans and arrangements, are authorized for issuance under the 2005 Plan.

A more detailed description of the terms of the 2005 Plan, as amended, is contained in the Company’s proxy statement for the Annual Meeting and the supplement to the proxy statement, which were filed with the Securities and Exchange Commission on April 14, 2010 and May 3, 2010, respectively. The foregoing summary is qualified in its entirety by the full text of the 2005 Plan, as amended, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
