Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION In acquiring 1,194,500 shares of Common Stock owned by Laminar prior to April 10, 2006, Laminar expended approximately $18,568,417 (excluding commissions) of its working capital.

Item 4. PURPOSE OF TRANSACTION Certain Reporting Persons and/or one or more affiliates of the Reporting Persons have 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 Reporting Persons and/or one or more affiliates of the Reporting Persons 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. Such waiver and approval were granted by resolutions adopted by the board of directors of the Issuer by unanimous written consent. On November 10, 2006, certain Reporting Persons and/or one or more affiliates of the Reporting Persons reached an understanding to make a joint bid to acquire all of the outstanding Common Stock not currently owned by the Reporting Persons. Certain Reporting Persons and/or one or more affiliates of the Reporting Persons have noted that, while they might enter into joint bidding arrangements with other persons, they currently have no such agreements with any other persons. 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 Reporting Persons and/or one or more affiliates of the Reporting Persons, to acquire by merger all of the outstanding shares of Common Stock not owned by the Reporting Persons (the "Proposal Letter") for $21 per share in cash. In connection with this offer, certain of the Reporting Persons and/or one or more affiliates of the Reporting Persons are still considering the appropriate deal structure and other related matters. Concurrently with the delivery of the Proposal Letter, certain Reporting Persons and/or one or more affiliates of the Reporting Persons and the Issuer entered into an exclusivity agreement (the "Exclusivity Agreement") which provides for an exclusivity period during which the parties thereto have agreed to negotiate in good faith the terms of a definitive acquisition agreement and all necessary ancillary agreements with respect to such acquisition agreement. The Proposal Letter and the Exclusivity Agreement are attached hereto as Exhibits 2 and 3, respectively, and are incorporated by reference herein. 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. 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.

DESCO LP as investment adviser and managing member of Valence and managing member of DESIM LLC 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 and to have the shared power to dispose or direct the disposition of the DESIM 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 the shared power to dispose or direct the disposition of the DESIM 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.

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.
