On November 17, 2006, CB Richard Ellis Group, Inc. (“CBRE”) and its wholly-owned subsidiary, CB Richard Ellis Services, Inc. (the “Company”), entered into a Third Supplemental Indenture, dated as of November 17, 2006, by and among the Company, CBRE, the subsidiary guarantors party thereto and U.S. Bank National Association, as trustee (the “Supplemental Indenture”). The Supplemental Indenture amends that certain Indenture, dated as of May 22, 2003, pursuant to which the Company’s 9 ³/4% Senior Notes due 2010 (the “Notes”) were issued (as amended and supplemented prior to November 17, 2006, the “Indenture”).

The Supplemental Indenture was entered into in connection with the Company’s tender offer and consent solicitation with respect to the Notes, which was commenced on November 3, 2006, following receipt by the Company of the requisite tenders and consents from holders of a majority in aggregate principal amount of the Notes outstanding, as of 5:00 p.m., New York City time, on Thursday, November 16, 2006. The Supplemental Indenture, when it becomes operative, will effect those amendments to the Indenture proposed in connection with the tender offer and consent solicitation, which amendments will eliminate substantially all of the restrictive covenants and eliminate or modify certain events of default and related provisions contained in the Indenture. The amendments to the Indenture will not become operative until the tendered Notes are accepted for purchase by the Company, pursuant to the terms of the tender offer and consent solicitation. After the amendments to the Indenture become operative, Notes that were not tendered or were not purchased in the tender offer and consent solicitation will remain outstanding and will be subject to the terms of the Indenture as modified by the Supplemental Indenture.

The foregoing description of the Supplemental Indenture and the amendments contained therein does not purport to be complete and is qualified in its entirety by reference to the Supplemental Indenture, a copy of which is attached hereto as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information set forth in Item 1.01 is incorporated by reference herein as such information relates to the Notes.

On November 17, 2006, CBRE issued a press release announcing (i) the receipt by the Company of the requisite consents in connection with the Company’s previously announced tender offer and consent solicitation with respect to the Notes and (ii) the pricing terms of the Company’s tender offer and consent solicitation. A copy of the press release is attached hereto as Exhibit 99.1.

The information included in this Item 7.01, including Exhibit 99.1, shall be deemed not to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, regardless of any incorporation by reference language in any such filing, except as expressly set forth by specific reference in such filing.
