Item 2.02. Results of Operations and Financial Condition.

On January 25, 2006, Siebel Systems, Inc. (the “Company”) issued a press release announcing its financial results for the fourth quarter ended December 31, 2005. A copy of the press release, dated as of January 25, 2006, is furnished as Exhibit 99.1 to this Current Report and is incorporated in this Item 2.02 by reference.

The press release is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or subject to the liabilities of that Section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended.

Item 8.01. Other Events.

To date, approximately 59% of the Company’s outstanding shares have been voted on the proposal to adopt the Agreement and Plan of Merger dated as of September 12, 2005, as amended, by and among Oracle Corporation, the Company, Ozark Holding Inc., Ozark Merger Sub Inc. and Sierra Merger Sub Inc. (the “Merger Agreement”). Of the shares voted, in excess of 98% have been voted in favor of the adoption of the Merger Agreement, which constitutes a majority of the Company’s outstanding shares. Accordingly, the Company expects that its stockholders will approve the adoption of the Merger Agreement at its Special Meeting of Stockholders to be held on January 31, 2006 (the “Special Meeting”). However, because stockholders can revoke their proxies at any time before the close of voting at the Special Meeting, the Company will not know definitively whether the stockholders have approved the adoption of the Merger Agreement until the time of the Special Meeting.

Item 9.01. Financial Statements and Exhibits.
