    Set forth below is the text of slides to be shown by the Registrant to certain employees of the Registrant in connection with informational meetings regarding a proposed merger transaction in which the Registrant would become a wholly-owned subsidiary of CBRE Holding, Inc., a Delaware corporation (the "Merger").

    These slides contain statements that are not historical facts but rather reflect current expectations concerning future results and events. These forward-looking statements are subject to risks, uncertainties and other factors, some of which are beyond our control, that could cause actual results and events to differ materially from those forecast or anticipated in the forward-looking statements. These risks, uncertainties and other factors include, but are not limited to, the following: changes in interest rates, and the availability, cost and terms of financing; the outcomes of pending lawsuits against us; economic conditions generally; demand for the services that we provide; competition; our ability to attract and retain qualified personnel; changes in business strategy or development plans; and other factors which are discussed in the preliminary proxy statement described below and other documents that we file with the Securities and Exchange Commission.

    No one should place undue reliance on these forward-looking statements, which reflect management's view only as of the date of this filing. All forward-looking statements included in these slides and all subsequent forward-looking statements attributable to the Registrant of persons acting on the Registrant's behalf, are expressly qualified in their entirety by these cautionary statements. The Registrant undertakes no obligation to publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date of this filing or to reflect the occurrence of unanticipated events.

    The Registrant filed a preliminary proxy statement regarding the Merger on April 12, 2001 and will file a definitive proxy statement regarding the Merger when it is available. Information regarding the identity of persons who, under rules of the Securities and Exchange Commission, may be considered participants in the solicitation of proxies from stockholders of the Registrant, and those persons' holdings of securities of the Registrant, are included in the preliminary proxy statement. Stockholders of the Registrant are urged to read the definitive proxy statement regarding the Merger when it is available, because it will contain important information. Copies of the proxy statements and related Rule 13e-3 Transaction Statement on Schedule 13E-3 may be obtained for free at the Securities and Exchange Commission website at www.sec.gov. These documents may also be obtained for free from the Registrant. Requests for copies should be directed to CB Richard Ellis Services, Inc., 505 Montgomery Street, Sixth Floor, San Francisco, California 94111, Attention: Walter Stafford, Secretary.
