SECURITY AND THE ISSUER This Amendment No. 2 to the Statement on Schedule 13D (this "Amendment") amends and restates the Statement on Schedule 13D originally filed by D. E. Shaw Laminar Portfolios, L.L.C., a Delaware limited liability company ("Laminar"), D. E. Shaw & Co., L.P., a Delaware limited partnership ("DESCO LP"), D. E. Shaw & Co., L.L.C., a Delaware limited liability company ("DESCO LLC"), D. E. Shaw Valence Portfolios, L.L.C., a Delaware limited liability company ("Valence") and David E. Shaw, a citizen of the United States of America, with the Securities and Exchange Commission on April 11, 2006 (the "Schedule 13D"), and the Amendment No. 1 to the Schedule 13 D filed by Laminar, DESCO LP, DESCO LLC, Valence, David E. Shaw and Ian Bruce Eichner, a citizen of the United States of America, with the Securities and Exchange Commission on November 13, 2006, relating to the common stock, par value $0.001 per share ("Common Stock"), of Riviera Holdings Corporation, a Nevada corporation (the "Issuer"), and is being filed pursuant to Rule 13d-1 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The principal executive offices of the Issuer are located at 2901 Las Vegas Boulevard South, Las Vegas NV 89109. Item 2. IDENTITY AND BACKGROUND (a), (f) This statement is filed on behalf of Laminar, DESCO LP, DESCO LLC, Valence and David E. Shaw (all of the foregoing collectively, the "Reporting Persons"). On December 14, 2006, the Reporting Persons and Ian Bruce Eichner entered into an agreement amending and restating the Amended and Restated Joint Filing Agreement dated as of November 10, 2006 (the " Second Amended and Restated Joint Filing Agreement") to, among other things, remove Ian Bruce Eichner as joint filer. The foregoing and subsequent references to, and descriptions of, the Second Amended and Restated Joint Filing Agreement are qualified in their entirety by reference to the Second Amended and Restated Joint Filing Agreement, the terms of which are attached hereto as Exhibit 1 and incorporated by reference herein. (b) The business address and principal office, as applicable, of all Reporting Persons is 120 West Forty-Fifth Street, Floor 39, Tower 45, New York, NY 10036. (c) The principal business of Laminar is that of a limited liability company focusing primarily on credit opportunities related investment strategies. The principal business of Valence is that of a limited liability company focusing primarily on equity- and equity-linked-securities related investment strategies. Neither Laminar nor Valence has any executive officers or directors. The principal business of DESCO LP is to act as an investment adviser to certain funds, including, without limitation, Laminar and Valence. DESCO LP is also the managing member of Valence and D. E. Shaw Investment Management, L.L.C. ("DESIM LLC"). The principal business of DESCO LLC is to act as managing member to certain funds, including, without limitation, Laminar. D. E. Shaw & Co., Inc., a Delaware corporation ("DESCO Inc."), is the general partner of DESCO LP. D. E. Shaw & Co. II, Inc., a Delaware corporation ("DESCO II, Inc."), is the managing member of DESCO LLC. David E. Shaw is the president and sole shareholder of DESCO Inc. and DESCO II, Inc. 7 (d), (e) During the last five years, neither any Reporting Person nor, to the best knowledge of any Reporting Person, any person named in Item 2, has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violations with respect to such laws. Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION In acquiring 1,194,500 shares of Common Stock owned by Laminar prior to December 13, 2006, Laminar expended approximately $18,568,417 (excluding commissions) of its working capital. In acquiring 24,900 shares of Common Stock owned by Valence prior to December 13, 2006, Valence expended approximately $548,851 (excluding commissions) of its working capital. Item 4. PURPOSE OF TRANSACTION Certain Reporting Persons and/or one or more affiliates of the Reporting Persons on the one hand and Ian Bruce Eichner on the other hand (all of the foregoing collectively, the "Bidders") had been granted a waiver by the board of directors of the Issuer of the applicability of Article III Section 7 of the Issuer's articles of incorporation and an approval, for the purpose of Section 78.438 of the Nevada Revised Statutes, of the joinder of certain Bidders with respect to (a) making a joint proposal to the board of directors of the Issuer, (b) engaging in discussions with representatives of the Issuer regarding a joint proposal, (c) modifying, supplementing or amending the terms and conditions of a joint proposal, (d) engaging in discussions with shareholders of the Issuer regarding their potential support for any potential merger agreement pursuant to a joint proposal, (e) negotiating (but not executing) option, voting or other agreements with shareholders of the Issuer with respect to a joint proposal, (f) negotiating a merger agreement and all related transaction agreements with the Issuer, (g) forming an acquisition vehicle and taking all necessary actions with respect to its capitalization and governance in connection with a joint proposal and all agreements and arrangements related thereto, (h) engaging in discussions with and negotiating the terms of any agreements with any potential debt financing sources or additional equity financing sources with respect to the financing of a joint proposal, (i) making any required filings under applicable laws or regulations in connection with the joint proposal or any contemplated transaction relating to such joint proposal, (j) engaging in discussions and/or meetings with Nevada and Colorado gaming regulatory authorities regarding the joint proposal, the proposed merger agreement, the acquisition vehicle, the potential debt financing and equity financing sources and potential financial structure, and other matters regarding the potential acquisition, and (k) taking all other actions that are a necessary and proper incident to making a joint proposal (the "Waiver and Approval"). The Waiver and Approval were granted by resolutions adopted by the board of directors of the Issuer by unanimous written consent. 8 On November 10, 2006, certain Bidders reached an understanding to make a joint bid to acquire all of the outstanding Common Stock not currently owned by the Reporting Persons or Ian Bruce Eichner. On November 10, 2006, a letter was sent to the board of directors of the Issuer proposing, on behalf of an entity to be formed by certain Bidders, to acquire by merger all of the outstanding shares of Common Stock not owned by the Reporting Persons or Ian Bruce Eichner (the "Proposal Letter") for $21 per share in cash. Concurrently with the delivery of the Proposal Letter, certain Bidders and the Issuer entered into an exclusivity agreement (the "Exclusivity Agreement") which provided for an exclusivity period during which the parties thereto agreed to negotiate in good faith the terms of a definitive acquisition agreement and all necessary ancillary agreements with respect to such acquisition agreement. On December 12, 2006, the effectiveness of the Waiver and Approval as well as the exclusivity period contemplated by the Exclusivity Agreement expired. Concurrently, certain Bidders withdrew their acquisition proposal contemplated by the Proposal Letter. In addition, the Reporting Persons on the one hand and Ian Bruce Eichner on the other hand terminated all other activities permitted by the Waiver and Approval. Therefore, the Reporting Persons on the one hand and Ian Bruce Eichner on the other hand are no longer required to file a joint statement on Schedule 13D. Except as contemplated in this Item 4, no Reporting Person has any plans or proposals of the types referred to in clauses (a) through (j) of Item 4 of Schedule 13D, although the Reporting Persons reserve the right to develop such plans or proposals. Item 5. INTEREST IN SECURITIES OF THE ISSUER (a), (b) Based upon the Issuer's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2006, there were 12,463,755 shares of Common Stock outstanding as of November 1, 2006. Based on the foregoing, the 1,194,500 shares of Common Stock beneficially owned by Laminar (the "Laminar Shares") represent approximately 9.6% of the shares of Common Stock issued and outstanding, the 24,900 shares of Common Stock beneficially owned by Valence (the "Valence Shares") represent approximately 0.2% of the shares of Common Stock issued and outstanding,and the 1,219,400 shares of Common Stock beneficially owned by DESCO LP (the "Subject Shares") represent approximately 9.8% of the shares of Common Stock issued and outstanding. The Subject Shares are comprised of the (i) 1,194,500 shares of Common Stock in the name of Laminar and (ii) 24,900 shares of Common Stock in the name of Valence. 9 Laminar will have the power to vote or to direct the vote of (and the power to dispose or direct the disposition of) the Laminar Shares. Valence will have the power to vote or to direct the vote of (and the power to dispose or direct the disposition of) the Valence Shares. Laminar disclaims beneficial ownership of the shares beneficially owned by Valence; and Valence disclaims beneficial ownership of the shares beneficially owned by Laminar. DESCO LP as Laminar's investment adviser and DESCO LLC as Laminar's managing member may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Laminar Shares. DESCO LP as investment adviser and managing member of Valence also may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Valence Shares. As managing member of DESCO LLC, DESCO II, Inc. may be deemed to have the shared power to vote or to direct the vote of (and the shared power to dispose or direct the disposition of) the Laminar Shares. As general partner of DESCO LP, DESCO, Inc. may be deemed to have the shared power to vote or to direct the vote of (and the shared power to dispose or direct the disposition of) the Laminar Shares and the Valence Shares. None of DESCO LP, DESCO LLC, DESCO, Inc., or DESCO II, Inc., owns any shares of Common Stock of the Issuer directly and each such entity disclaims beneficial ownership of the Subject Shares. David E. Shaw does not own any shares of the Issuer directly. By virtue of David E. Shaw's position as president and sole shareholder of DESCO, Inc., which is the general partner of DESCO LP, and by virtue of David E. Shaw's position as president and sole shareholder of DESCO II, Inc., which is the managing member of DESCO LLC, David E. Shaw may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Laminar Shares and the Valence Shares and, therefore, David E. Shaw may be deemed to be the beneficial owner of the Subject Shares. David E. Shaw disclaims beneficial ownership of the Subject Shares. As of the date hereof, neither any Reporting Person, nor to the best knowledge of any Reporting Person, any of the persons set forth in Item 2, owns any shares of Common Stock other than the Subject Shares. (c) On December 12, 2006, in brokered transactions, (i) Valence sold 300 shares of Common Stock for an average price of $22.57 per share, (ii) DESIM directed an existing account under its management to sell 200 shares of Common Stock for an average price of $22.605 per share, and (iii) DESIM assumed management of a new account which contained 400 shares of Common Stock and directed that account to sell those shares for an average price of $22.635 per share. Except as set forth above, within the last 60 days, no other transactions in shares of Common Stock were effected by any Reporting Person, or to the best knowledge of any Reporting Person, any of the persons set forth in Item 2. 10 (d) No person other than the Reporting Persons has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Subject Shares. Clause (e) of Item 5 of Schedule 13D is not applicable. Item 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Except for the matters described herein, neither the Reporting Persons nor, to the best knowledge of any Reporting Person, any of the persons listed in Item 2 has any contract, arrangement, understanding or relationship with any person with respect to any securities of the Issuer.
