Westerman, as last amended by Amendment No. 2, as filed on November 5, 2004, with respect to the beneficial ownership of Mr. Westerman in the common stock, par value $0.001 per share (the "Common Stock"), of Riviera Holdings Corporation, a Nevada corporation (the "Issuer"). Except as specifically provided herein, this Amendment does not modify any of the information previously reported on the Schedule 13D, as amended. ITEM 4. PURPOSE OF TRANSACTION On December 22, 2005, Mr. Westerman and The William L. Westerman 2004 Revocable Family Trust, a trust formed under the laws of Nevada which is controlled by Mr. Westerman (the "Trust"), entered into a Stock Purchase Agreement (the "Purchase Agreement") with Flag Luxury Riv, LLC, a Delaware limited liability company, Rivacq LLC, a Delaware limited liability company, and High Desert Gaming LLC, a Delaware limited liability company (collectively, "Buyers"). The Purchase Agreement provides that Mr. Westerman is acting solely in his capacity as stockholder and not as an officer, director or representative of the Issuer. Pursuant to the Purchase Agreement, Mr. Westerman and the Trust (collectively, "Sellers") agreed to sell a total of 1,000,000 shares of Common Stock (the "First Purchase") held by the Trust to Buyers as allocated below for a total of $15,000,000 ($15.00 per share) on a closing date between January 3, 2006 and January 10, 2006. In addition to the First Purchase, the Purchase Agreement provides for the following transaction subject to various conditions: (1) the sale of a total of 650,000 shares of Common Stock (the "Second Purchase") held by the Trust to Buyers as allocated below for a total of $9,750,000 ($15.00 per share); and (2) the grant of an option (the "Option") to purchase up to 441,471 shares of Common Stock (the "Option Shares") held by the Trust to Buyers as allocated among the Buyers below at a price of $15.00 per share. The First Purchase, Second Purchase, and Option Shares are allocated among Buyers as follows: ---------------------- ----------- ----------- --------- ----------- ---------- Number of Number of First First Second Second Number of Purchase Purchase Purchase Purchase Option Buyer Shares Price Shares Price Shares ---------------------- ----------- ----------- --------- ----------- ---------- Flag Luxury Riv, LLC 400,000 $6,000,000 260,000 $3,900,000 176,588 ---------------------- ----------- ----------- --------- ----------- ---------- Rivacq LLC 300,000 $4,500,000 195,000 $2,925,000 132,442 ---------------------- ----------- ----------- --------- ----------- ---------- High Desert Gaming LLC 300,000 $4,500,000 195,000 $2,925,000 132,441 ---------------------- ----------- ----------- --------- ----------- ---------- Total 1,000,000 $15,000,000 650,000 $9,750,000 441,471 ---------------------- ----------- ----------- --------- ----------- ---------- The obligations of Sellers and Buyers to consummate the Second Purchase are subject to various conditions. The material conditions for Sellers include the approval by the Nevada gaming regulators of the acquisition by Buyers of the Second Purchase shares (the "Nevada Gaming Approval"). The material conditions for Buyers include the receipt of the Nevada Gaming Approval and the adoption by the Issuer's board of directors (the "Board") of certain waivers and approvals (the "Board Approvals"). The Board Approvals include: (1) the waiver, in accordance with subsection 7(g) of the Issuer's Articles of Incorporation, of the voting limitation on stockholders with more than 10% of Issuer's stock set forth in subsection 7(b) of the Articles of Incorporation;(ii) the approval of the purchase of the Second Purchase shares and the Option Shares pursuant to Section 78.438(1) of the Nevada Revised Statutes; and (3) the approval of the acquisition by Buyers, whether by merger or otherwise, of control of the Issuer (an "Acquisition Transaction"). The Option is effective upon the issuance of the Board Approvals and may be exercised in increments of 20,000 shares or more. The obligations of Sellers and Buyers to consummate the exercise of the Option, whether in whole or in part, are the same as those that apply to the Second Purchase. Notwithstanding the Option, the Trust may make charitable donations of up to 100,000 shares of Common Stock. Under the Purchase Agreement, in addition to the First Purchase, the Second Purchase and the Option, Mr. Westerman has agreed, subject to this fiduciary duties as an officer and director of the Issuer, to: (1) assist and cooperate with the Buyers in obtaining the Nevada Gaming Approval as well as such approvals of the Nevada, Colorado and other gaming authorities as may be necessary to consummate an Acquisition Transaction; and (2) propose to the Board that a vacancy be created on the Board or that the Board be expanded and that a candidate nominated by Buyers be appointed to the Board. Further, Sellers have agreed to: (1) subject to the issuance of the Board Approvals, to grant an irrevocable proxy to Flag Luxury Riv, LLC or its designee to vote (or in the case of any shares beneficially owned by Mr. Westerman through the Issuer's Employee Stock Ownership Plan (the "ESOP"), to direct the ESOP trustee to vote), at any meeting of the Issuer's stockholders or in any action by written consent of the Issuer's stockholders, all of the shares of Common Stock held by Mr. Westerman or the Trust in favor of the approval of any Acquisition Transaction and against any action, agreement or transaction that would result in the Issuer's obligations under an Acquisition Agreement with the Buyers with respect to an Acquisition Transaction (an "Acquisition Agreement") not being fulfilled and (2) to cause any of the shares of Common Stock held by Mr. Westerman or the Trust to be voted in accordance with the foregoing. The Purchase Agreement will automatically terminate upon the earliest of: (1) the consummation of an Acquisition Transaction; (2) 6 months following the date of the Stock Purchase Agreement in the event an Acquisition Agreement has not been executed by such date; and (3) (a) in the event that an Acquisition Agreement is entered into and is terminated in circumstances where the Issuer is potentially required to pay to Buyers a termination fee or similar fee, 12 months following the date of such Acquisition Agreement or (b) in the event such Acquisition Agreement is terminated for any other reason, upon such termination. The Purchase Agreement provides that the Buyers' current intent is to enter into negotiations with the Board with the objective of entering into an agreement with respect to an Acquisition Transaction as soon as practicable on terms reasonably acceptable to the Buyers providing for an Acquisition Transaction at a price of not less than $15.00 per share of Common Stock in cash; provided, however, that Buyers and Sellers acknowledge that, since the Company's press release of November 8, 2005 announcing the Company's conclusion of its strategic process, the Board has not considered any Acquisition Transaction and there is no assurance that any such Acquisition Transaction can be negotiated. The foregoing references to, and descriptions of, the Purchase Agreement are qualified in their entirety by reference to the Purchase Agreement, the terms of which are incorporated herein by reference to Exhibit 10.1 hereto. Since the Purchase Agreement provides for certain arrangements among Sellers and Buyers with respect to, among other things, the voting of Common Stock, Sellers and Buyers may be deemed to be a "group" as referred to in Rule 13d-5 under the Securities Exchange Act of 1934 (the "Exchange Act"). Neither the filing of this Amendment nor any of its contents shall be deemed to constitute an admission that the Sellers are members of a "group" for purposes of Rule 13d-5 with any of the Buyers, or that such "group" exists, and the Sellers expressly disclaim the existence, or membership in, any such "group" and beneficial ownership of Common Stock held by any of such persons. Sellers understand that Buyers will be filing a Schedule 13D with respect to, among other things, the Purchase Agreement containing information about Buyers. Sellers are not responsible for any information or statements contained in such Schedule 13D. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER (a) As of December 22, 2005, after giving effect to the First Purchase by Buyers, Mr. Westerman beneficially owned 1,099,715 shares of Common Stock, representing 8.86% of the outstanding shares of Common Stock on that date. (b) As the sole trustee and beneficiary of the Trust, Mr. Westerman has sole voting power and sole dispositive power as to all of his shares of Common Stock reported in Item 5(a) above, except for 4,122 shares that he holds through the ESOP. All of the shares of Common Stock held by the ESOP are voted on each proposal in proportion to the voting instructions received by the Trustee of the ESOP (the "ESOP Trustee") from all ESOP participants who submit voting instructions. For example, if: (1) the ESOP holds 1,000 shares of Common Stock; (2) the ESOP Trustee receives voting instructions from participants on whose behalf the ESOP holds only 500 shares; and (3) those participants, in the aggregate, instruct the ESOP Trustee to vote 300 shares in favor of a proposal and 200 shares against it, then 600 shares held by the ESOP will be voted for the proposal and 400 shares will be voted against it. The ESOP Trustee has the power to sell or otherwise dispose of Common Stock that the ESOP holds. In exercising this power, the ESOP Trustee normally considers the views of the ESOP's Administrative Committee, which consists of officers (including Mr. Westerman) of the Issuer or its subsidiaries. (c) Other than as reported in this Amendment, Mr. Westerman has not effected any transactions involving Common Stock during the past 60 days. (d) No person other than Mr. Westerman has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Stock that he beneficially owns. (e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Except as described in Item 4 of this Amendment, Mr. Westerman has not entered into any contracts, arrangements, understandings or relationships (legal or otherwise) with any person with respect to any securities of the Issuer, including but not limited to the transfer or voting of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.
