Underwriting Agreement

On March 5, 2012, Pinnacle Entertainment, Inc., a Delaware corporation (the “Company”), and certain of its subsidiaries named therein (the “Guarantors”), entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Barclays Capital Inc., Credit Agricole Securities (USA) Inc., Deutsche Bank Securities Inc. and UBS Securities LLC, as Representatives of the several underwriters named therein (collectively, the “Underwriters”), to sell $325 million aggregate principal amount of the Company’s 7.75% Senior Subordinated Notes due 2022 (the “Notes”) to the Underwriters (the “Offering”).

The closing of the sale of the Notes is expected to occur on March 19, 2012. The net proceeds from the offering, after deducting the Underwriters’ discounts and commissions and the estimated offering expenses payable by the Company, are expected to be approximately $318.5 million. The Offering is conditioned on the concurrent closing of an incremental term loan (the “Term Loan”) under the Company’s Credit Agreement (as defined below).

Certain of the Underwriters and their affiliates have performed and may in the future provide various financial advisory, investment banking, and commercial banking services for the Company and its affiliates from time to time, for which they have received customary fees and expenses. In particular, certain of the Underwriters or their affiliates are agents and/or lenders on the Company’s Credit Agreement. Specifically, an affiliate of Barclays Capital Inc. acts as Administrative Agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC act as Joint Lead Arrangers and Joint Book Runners and certain of the Underwriters or their affiliates are Syndication Agent, Senior Managing Agent or lenders. The Company expects to use the net proceeds of the Offering and the Term Loan to redeem the Company’s 7.5% senior subordinated notes due 2015 (the “7.5% Notes”). Certain of the Underwriters or their affiliates own the 7.5% Notes and therefore will receive a portion of the net proceeds of the Term Loan and/or the Offering. In addition, from time to time, certain of the Underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities, and may do so in the future.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the Underwriting Agreement, which is attached to this Current Report on Form 8-K as Exhibit 1.1 and is incorporated herein by reference.

The Offering was made pursuant to a shelf registration statement on Form S-3 (File No. 333-179890), which became effective upon its filing with the Securities and Exchange Commission (the “SEC”) on March 5, 2012 (the “Form S-3”).

Consent Under Credit Agreement

On March 5, 2012, the Company entered into a Consent Under Fourth Amended and Restated Credit Agreement (the “Consent”) with Barclays Bank, PLC, as Administrative Agent, and various lenders thereto (the “Lenders”). The Consent was entered into in connection with the Fourth Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of August 2, 2011, among the Company, the various lenders referred to therein, Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P.Morgan Securities LLC as Joint Lead Arrangers and Joint Book Runners, Bank of America, N.A., JPMorgan Chase Bank, N.A., Credit Agricole Corporate and Investment Bank, Deutsche Bank Securities Inc. and Wells Fargo Bank, N.A., as the Syndication Agents, UBS Securities LLC and Capital One National Association as the Senior Managing Agents, and Barclays Bank PLC, as the Administrative Agent.

The Credit Agreement provides that the Company may use the proceeds of an incremental term loan to repurchase or redeem up to $100,000,000 in senior subordinated notes of the Company. Pursuant to the Consent, the Administrative Agent and the Lenders agreed to permit the Company to use the proceeds of an incremental term loan to refinance a portion of the Company’s outstanding $385,000,000 aggregate principal amount of 7.5% Notes without reducing or counting against the $100,000,000 limitation in the Credit Agreement.

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

On March 5, 2012, the Company issued a press release announcing that it intended to offer $250 million aggregate principal amount of new senior subordinated notes due 2022 pursuant to the Form S-3 and that it was in the process of seeking commitments for a $250 million Term Loan. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

In addition, on March 5, 2012, the Company issued a press release announcing the pricing of $325 million aggregate principal amount of new 7.75% senior subordinated notes due 2022, which will be issued pursuant to the Form S-3. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.2 and is incorporated herein by reference.

On March 5, 2012, the Company also issued a press release announcing that it was commencing a cash tender offer and consent solicitation for any and all of its outstanding 7.5% Notes. A copy of the press release is attached to this Form 8-K as Exhibit 99.3 and is incorporated herein by reference.

On March 5, 2012, the Company issued a press release announcing that it terminated its cash tender offer and consent solicitation for any and all of its outstanding 7.5% Notes. The Company also announced that it would redeem the 7.5% Notes at a price equal to 103.750% of par, plus accrued and unpaid interest pursuant to a conditional notice of optional redemption that it mailed to the holders of the 7.5% Notes pursuant to the indenture governing the 7.5% Notes. The redemption of the 7.5% Notes is conditioned upon the closing and receipt of net proceeds from the Offering and the Term Loan in an amount sufficient to redeem the 7.5% Notes. The redemption date is scheduled for March 20, 2012, subject to the satisfaction of the financing condition described above. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.4 and is incorporated herein by reference.

Further, on March 8, 2012, the Company issued a press release announcing that the Company has obtained commitments for a $325 million Term Loan. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.5 and is incorporated herein by reference.
