Dear Sirs:

         1.  Introductory.  BLUM CB Corp., a Delaware corporation (the
"Issuer"), which is a wholly owned subsidiary of CBRE Holding, Inc.
("Holdings"), a Delaware corporation, proposes, subject to the terms and
conditions stated herein, to issue and sell to Credit Suisse First Boston
Corporation ("CSFBC"), Credit Lyonnais Securities (USA) Inc., HSBC Securities
(USA) Inc. and Scotia Capital (USA) Inc. (the "Initial Purchasers") $229,000,000
aggregate principal amount of its 11 1/4% Senior Subordinated Notes Due 2011
(the "Notes"). The Notes will be unconditionally guaranteed on a senior
subordinated basis by Holdings (the "Parent Guaranty"; the Parent Guaranty,
together with the Notes, the "Offered Securities"). The Offered Securities are
to be issued pursuant to an indenture (the "Indenture") to be dated as of June
7, 2001 (the "Closing Date"), between the Issuer, Holdings and State Street Bank
and Trust Company of California, N.A., as trustee (the "Trustee"). As part of
the transactions (the "Transactions") as defined in the "Description of the
Notes" and as described under the heading "The Transactions" in the Offering
Document (as defined herein), the Issuer will merge with and into CB Richard
Ellis Services, Inc., a Delaware corporation (the "Company"), with the Company
as the surviving corporation in such merger (the "Merger"). As a result of the
Merger, all of the Issuer's obligations under the Notes, the Indenture, the
Registration Rights Agreement and the Escrow Agreement (as each term is defined
herein) will, by operation of law, become obligations of the Company.
Concurrently with the consummation of the Merger, (1) the Company and the
Subsidiary Guarantors (as defined herein) will execute counterparts to this
Agreement and the Registration Rights
<PAGE>

Agreement, which will cause the obligations of the Issuer under this
Agreement and the Registration Rights Agreement which survive past the closing
date of the Merger to be contractually assumed by the Company and the Subsidiary
Guarantors, (2) the Company will enter into a supplemental indenture relating to
the Indenture (the "Supplemental Indenture"), which Supplemental Indenture will
cause the obligations of the Issuer under the Indenture to be assumed by the
Company, (3) the Company will enter into a credit agreement  (together with the
related guaranties and security documents, the "Credit Agreement") among itself,
the guarantors named therein, Credit Suisse First Boston, New York branch, as
administrative agent, and the lenders named therein and (4) each subsidiary of
the Company that is a guarantor under the Credit Agreement (the "Subsidiary
Guarantors") will guarantee the Notes on an unconditional senior subordinated
basis pursuant to the terms of the Supplemental Indenture (the "Subsidiary
Guaranties"; after the consummation of the Merger, the Subsidiary Guaranties,
the Notes and the Parent Guaranty are collectively referred to as the "Offered
Securities").

     If the Closing Date occurs prior to the consummation of the Merger, the
Issuer will, on the Closing Date, deposit with State Street Bank and Trust
Company of California, N.A. (the "Escrow Agent") the gross proceeds of the
offering of the Offered Securities, together with an amount of cash or treasury
securities (the "Escrowed Funds") so that the amount in escrow will be
sufficient to pay the special mandatory redemption price for the Offered
Securities, when and if due. In the event that the Merger and the other
Transactions are not consummated on or prior to the 75th day after the closing
of this offering or the Merger Agreement is terminated at any time prior
thereto, the Issuer will redeem the Offered Securities at a redemption price
equal to 100% of the accreted value of the Offered Securities, plus accrued and
unpaid interest to the date of redemption. If the Merger and the other
Transactions are consummated on or prior to the 75th day after the closing of
this offering, the Escrowed Funds will be released to the Issuer in connection
with the closing of the Merger.

     This Agreement (including the counterparts to be executed concurrently with
the consummation of the Merger), the Indenture, the Supplemental Indenture, the
Offered Securities, the Exchange Securities (as defined in the Registration
Rights Agreement), the Registration Rights Agreement (including the counterparts
to be executed concurrently with the consummation of the Merger) and the Escrow
Agreement are sometimes referred to in this Agreement collectively as the
"Operative Documents". All material agreements and instruments relating to the
Transactions (including, but not limited to, the Merger Agreement and the Credit
Agreement), are sometimes referred to in this Agreement collectively as the
"Transaction Agreements". The Operative Documents and the Transactions
Agreements are sometimes referred to in this Agreement collectively as the
"Transaction Documents". References in this Agreement to the subsidiaries of the
Company shall include all direct and indirect subsidiaries of the Company after
the consummation of the Merger.

     Capitalized terms used but not defined herein shall have the meanings given
to such terms in the Offering Document (as defined below).

     The Issuer and Holdings hereby agree with the Initial Purchasers as
follows:

     2.  Representations and Warranties of the Issuer.  The Issuer and Holdings
represent and warrant to, and agree with, the Initial Purchasers that:

          (a)  A preliminary offering circular dated May 23, 2001 and an
     offering circular dated the date of this Agreement relating to the Offered
     Securities to be purchased by the Initial Purchasers have been prepared by

     Circular") and offering circular, as the same may be supplemented prior to
     the closing of the offering (the "Offering Circular"), are hereinafter
     collectively referred to as the "Offering Document". On the date of this
     Agreement, the Offering Document does not include any untrue statement of a

<PAGE>

     material fact or omit to state any material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading. The preceding sentence does not apply to
     statements or omissions from the Offering Document based upon written
     information furnished to the Company by any Initial Purchaser through CSFBC
     specifically for use therein, it being understood and agreed that the only
     such information is that described in Section 7(b) hereof.

          (b)   Each of the Issuer, Holdings and the Company has been duly
     incorporated and is an existing corporation in good standing under the laws
     of the jurisdiction of its incorporation, with corporate power and
     authority to own its properties and conduct its business as described in
     the Offering Document, and each of the Issuer, Holdings and the Company is
     duly qualified to do business as a foreign corporation in good standing in
     all other jurisdictions in which its ownership or lease of property or the
     conduct of its business requires such qualification, except to the extent
     that the failure to be so qualified or to be in good standing would not
     have a material adverse effect on the business, financial condition or
     results of operation of the Company and its subsidiaries, taken as a whole
     (a "Material Adverse Effect").

          (c)   Each subsidiary of the Company has been duly incorporated and is
     an existing corporation, limited liability company or limited partnership,
     as the case may be, in good standing (if applicable) under the laws of the
     jurisdiction of its incorporation or organization, with corporate power and
     authority to own its properties and conduct its business as described in
     the Offering Document, and each subsidiary of the Company is duly qualified
     to do business as a foreign corporation, limited liability company or
     limited partnership, as the case may be, in good standing (if applicable)
     in all other jurisdictions in which its ownership or lease of property or
     the conduct of its business requires such qualification, except to the
     extent that the failure to be so qualified or to be in good standing would
     not have a Material Adverse Effect; all of the issued and outstanding
     capital stock, ownership interests, or partnership interests, as the case
     may be, of each subsidiary of the Company has been, and immediately
     following the Merger will be, duly authorized and validly issued and, in
     the case of capital stock, is fully paid and nonassessable; and except as
     disclosed in the Offering Document and for pledges in favor of Credit
     Suisse First Boston, New York branch, as collateral agent under the Credit
     Agreement, the capital stock, ownership interests, or partnership
     interests, as the case may be, of the Company and each subsidiary owned by
     the Company, directly or through subsidiaries, will be owned free from
     liens, encumbrances and defects immediately following the Merger and the
     other Transactions.

          (d)   On the Closing Date, the Indenture will be duly authorized by
     the Issuer and Holdings, and the Supplemental Indenture will be duly
     authorized by the Company and the Subsidiary Guarantors upon consummation
     of the Merger; on the Closing Date, the Offered Securities will be duly
     authorized by the Issuer and Holdings, and the Subsidiary Guaranties will
     be duly authorized by the Subsidiary Guarantors upon consummation of the
     Merger; and when the Offered Securities are delivered and paid for pursuant
     to this Agreement and the Indenture on the Closing Date (as defined below),
     assuming due authorization, execution and delivery of the Indenture by the
     Trustee, the Indenture will have been duly executed and delivered by the
     Issuer and Holdings, such Offered Securities will have been duly executed,
     authenticated, issued and delivered by the Issuer and Holdings (assuming
     authentication by the Trustee in accordance with the provisions of the
     Indenture) and will conform in all material respects to the description
     thereof contained in the Offering Document and the Indenture and such
     Offered Securities will constitute valid and legally binding obligations of
     the Issuer and Holdings and, upon execution of the Supplemental Indenture,
     the Company and the Subsidiary Guarantors, enforceable in accordance with
     their terms and entitled to the benefits of the Indenture or the
     Supplemental Indenture, as the case may be (assuming that the Indenture and
     the Supplemental Indenture are valid and legally binding obligations of the
     Trustee),

                                       3
<PAGE>

     subject to (i) the effects of bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium or similar laws of general applicability
     relating to or affecting creditors' rights, (ii) general principles of
     equity (regardless of whether enforceability is considered in a proceeding
     at law or in equity) and (iii) an implied covenant of good faith and fair
     dealing.

          (e)   On the Closing Date, the Exchange Securities will have been duly
     authorized by the Issuer and Holdings, and upon consummation of the Merger,
     the Exchange Securities will be duly authorized by the Company and the
     Subsidiary Guarantors. When the Exchange Securities are issued, executed
     and authenticated in accordance with the terms of the Exchange Offer and
     the Indenture, the Exchange Securities (assuming authentication by the
     Trustee in accordance with the provisions of the Indenture) will be
     entitled to the benefits of the Indenture and will be the valid and binding
     obligations of the Company, Holdings and the Subsidiary Guarantors,
     enforceable against the Company, Holdings and the Subsidiary Guarantors in
     accordance with their terms (assuming that the Indenture and the
     Supplemental Indenture are valid and legally binding obligations of the
     Trustee), subject to (i) the effects of bankruptcy, insolvency, fraudulent
     transfer, reorganization, moratorium or similar laws of general
     applicability affecting creditors' rights and (ii) general principles of
     equity (regardless of whether enforceability is considered in a proceeding
     at law or in equity).

          (f)   On the Closing Date, the Indenture will conform in all material
     respects to the requirements of the Trust Indenture Act of 1939, as amended
     (the "TIA" or the "Trust Indenture Act"), and the rules and regulations of
     the Securities and Exchange Commission (the "Commission") applicable to an
     indenture which is qualified thereunder.

          (g)   Except as disclosed in the Offering Document, there are no
     contracts, agreements or understandings between the Issuer, Holdings or the
     Company and any person that would give rise to a valid claim against the
     Issuer, Holdings, the Company or any Initial Purchaser for a brokerage
     commission, finder's fee or other like payment in connection with the
     Offered Securities.

          (h)   No consent, approval, authorization, or order of, or filing
     with, any governmental agency or body or any court is required for the
     consummation of the transactions contemplated by this Agreement, the
     Registration Rights Agreement dated the date hereof, between the Issuer,
     Holdings and the Initial Purchasers (the "Registration Rights Agreement"),
     or any other Transaction Document, in each case, in connection with the
     consummation of the transactions contemplated therein, except as may be
     required under the Securities Act, the TIA and the rules and regulations of
     the Commission thereunder with respect to the Exchange Offer Registration
     Statement or the Shelf Registration Statement (each as defined in the
     Registration Rights Agreement) or the transactions contemplated by the
     Registration Rights Agreement, or any state or foreign securities laws or
     by the regulations of the National Association of Securities Dealers, Inc.

          (i)   Assuming the accuracy of the representations of the other
     parties thereto and the performance by those parties of their agreements
     therein, the execution, delivery and performance by each of the Issuer,
     Holdings, the Company and the subsidiaries of the Company (to the extent a
     party thereto) of each of the Transaction Documents and their compliance
     with the terms and provisions thereof and the consummation of the
     Transactions will not result in a breach or violation of any of the terms
     and provisions of, or constitute a default under, (i) any statute, rule,
     regulation or order of any governmental agency or body or any court,
     domestic or foreign, that has jurisdiction over the Issuer, Holdings, the
     Company, or any of the Company's subsidiaries or any of their properties,
     (ii) the Transaction Documents or any agreement or instrument to which the
     Issuer, Holdings, the Company or any of the Company's subsidiaries is a
     party or by which the Issuer, Holdings, the Company or any of the Company's
     subsidiaries is bound or to which any of the properties of the Issuer,
     Holdings, the Company or the Company's subsidiaries is subject or (iii) the
     charter, by-laws

     or similar governing documents of the Issuer, Holdings, the Company or any
     of the Company's subsidiaries, except, with respect to clauses (i) and
     (ii), where such breach, violation or default would not have a Material
     Adverse Effect or would not have a material adverse effect on the business,
     financial condition or results of operation of the Issuer or Holdings or
     the Company or its subsidiaries, taken as a whole; the Issuer has full
     corporate power and authority to authorize, issue and sell the Notes as
     contemplated by this Agreement.

          (j)   None of the Issuer, Holdings, the Company or any of the
     subsidiaries of the Company is in breach or violation of any of the terms
     and provisions of, or in default under, (i) any statute, rule, regulation
     or order of any governmental agency or body or any court, domestic or
     foreign, that has jurisdiction over the Issuer, Holdings, the Company, or
     any of the Company's subsidiaries or any of their properties, (ii) any
     agreement or instrument to which the Issuer, Holdings, the Company or any
     of the Company's subsidiaries is a party or by which the Issuer, Holdings,
     the Company or any of the Company's subsidiaries is bound or to which any
     of the properties of the Issuer, Holdings, the Company or the Company's
     subsidiaries is subject or (iii) the charter, by-laws or similar governing
     document of the Issuer, Holdings, the Company or any of the Company's
     subsidiaries, except with respect to clauses (i) and (ii) for any breaches,

     would not have a material adverse effect on the business, financial
     condition or results of operation of the Issuer or Holdings or the Company
     or its subsidiaries, taken as a whole.

          (k)   This Agreement has been duly authorized, executed and delivered
     by the Issuer and Holdings. Each of the other Operative Documents has been,
     or as of the Closing Date will have been, duly authorized, executed and
     delivered by the Issuer and Holdings (to the extent a party thereto), and
     immediately upon consummation of the Merger will be duly authorized,
     executed and delivered by each of Holdings, the Company and the Subsidiary
     Guarantors (to the extent a party thereto). All of the Transaction
     Agreements have been or will be as of or on the Merger closing date, duly
     authorized, executed and delivered by each of Holdings, the Company and the
     Company's subsidiaries (to the extent a party thereto). Each Transaction
     Document conforms or will conform in all material respects to the
     descriptions thereof contained in the Offering Document and each Operative
     Document (other than this Agreement) is or will constitute valid and
     legally binding obligations of the Issuer and Holdings (to the extent a
     party thereto) and each Transaction Agreement constitutes or will
     constitute valid and legally binding obligations of Holdings, the Company
     and each Subsidiary Guarantor (to the extent a party thereto), enforceable
     in accordance with its respective terms, except that any rights to
     indemnity and contribution may be limited by federal and state securities
     laws and public policy considerations and subject to (i) bankruptcy,
     insolvency, fraudulent transfer, reorganization, moratorium and similar
     laws of general applicability relating to or affecting creditors' rights,
     (ii) general principles of equity (regardless of whether enforceability is
     considered in a proceeding at law or in equity) and (iii) an implied
     covenant of good faith and fair dealing.

          (l)   Except as disclosed in the Offering Document, the Company and
     its subsidiaries have, or following consummation of the Merger will have,
     good and marketable title to all real properties and all other properties
     and assets owned by them that are material to the Company and its
     subsidiaries taken as a whole, in each case free from liens, encumbrances
     and defects that would materially affect the value thereof or materially
     interfere with the use made or proposed to be made thereof by them; and
     except as disclosed in the Offering Document, the Company and its
     subsidiaries hold any leased real or personal property that is material to
     the Company and its subsidiaries taken as a whole under valid and
     enforceable leases with no exceptions that would materially interfere with
     the use made or proposed to be made thereof by them.

          (m)   The Company and its subsidiaries possess adequate certificates,
     authorities or permits issued by appropriate governmental agencies or
     bodies necessary to conduct the business now

                                       5
<PAGE>

     operated by them and have not received any notice of proceedings relating
     to the revocation or modification of any such certificate, authority or
     permit that, if determined adversely to the Company or any of its
     subsidiaries, would individually or in the aggregate have a Material
     Adverse Effect.

          (n)  No labor dispute with the employees of the Company or any
     subsidiary exists or, to the knowledge of the Issuer or Holdings, is
     imminent that would reasonably be expected to have a Material Adverse
     Effect.

          (o)  The Company and its subsidiaries own, possess or can acquire on
     reasonable terms, adequate trademarks, trade names and other rights to
     inventions, know-how, patents, copyrights, confidential information and
     other intellectual property (collectively, "intellectual property rights")
     necessary to conduct the business now operated by them, or presently
     employed by them, and have not received any notice of infringement of or
     conflict with asserted rights of others with respect to any intellectual
     property rights that, if determined adversely to the Company or any of its
     subsidiaries, would individually or in the aggregate have a Material
     Adverse Effect.

          (p)  Except as disclosed in the Offering Document, neither the Company
     nor any of its subsidiaries is in violation of any statute, rule,
     regulation, decision or order of any governmental agency or body or any
     court, domestic or foreign, relating to the use, disposal or release of
     hazardous or toxic substances or relating to the protection or restoration
     of the environment or human exposure to hazardous or toxic substances
     (collectively, "environmental laws"), owns or operates any real property
     contaminated with any substance that is subject to any environmental laws,
     is liable for any off-site disposal or contamination pursuant to any
     environmental laws, or is subject to any claim relating to any
     environmental laws, which violation, contamination, liability or claim
     would individually or in the aggregate have a Material Adverse Effect; and
     neither the Issuer nor Holdings is aware of any pending investigation which
     might lead to such a claim.

          (q)  Except as disclosed in the Offering Document, there are no
     pending actions, suits or proceedings against or affecting the Issuer,
     Holdings or the Company, any of the Company's subsidiaries or any of their
     respective properties that (i) if determined adversely to the Company or
     any of its subsidiaries, would individually or in the aggregate have a
     Material Adverse Effect, (ii) would materially and adversely affect the
     ability of the Issuer, Holdings or the Company to perform its obligations
     under the Transaction Documents or (iii) are otherwise material in the
     context of the sale of the Offered Securities; and no such actions, suits
     or proceedings are, to the knowledge of the Issuer or Holdings, threatened
     or contemplated.

          (r)  The historical financial statements included in the Offering
     Document present fairly the financial position of the Company and its
     consolidated subsidiaries as of the dates shown and their results of
     operations and cash flows for the periods shown, and such financial
     statements have been prepared in conformity with the generally accepted
     accounting principles in the United States applied on a consistent basis
     and the assumptions used in preparing the pro forma financial statements
     included in the Offering Document provide a reasonable basis for presenting
     the significant effects directly attributable to the transactions or events
     described therein, the related pro forma adjustments give appropriate
     effect to those assumptions, and the pro forma columns therein reflect the
     proper application of those adjustments to the corresponding historical
     financial statement amounts.

          (s)  To our knowledge, no "nationally recognized statistical rating
     organization" as such term is defined for purposes of Rule 436(g)(2) under
     the Securities Act (i) has imposed (or has informed the Issuer, Holdings,
     the Company or any of the Subsidiary Guarantors that it is considering
     imposing) any condition (financial or otherwise) on the Issuer's,
     Holding's, the Company's or any Subsidiary Guarantor's retaining any rating
     assigned to the Issuer, Holdings, the Company or any

                                       6
<PAGE>

     Subsidiary Guarantor, any securities of the Issuer, Holdings, the Company
     or any Subsidiary Guarantor or (ii) has indicated to the Issuer, Holdings,
     the Company or any Subsidiary Guarantor that it is considering (a) the
     downgrading, suspension, or withdrawal of, or any review for a possible
     change that does not indicate the direction of the possible change in, any
     rating so assigned or (b) any change in the outlook for any rating of the
     Issuer, Holdings, the Company, any Subsidiary Guarantor or any securities
     of the Issuer, Holdings, the Company or any Subsidiary Guarantor.

          (t)  Except as disclosed in the Offering Document, since the date of
     the latest audited financial statements of the Company included in the
     Offering Document, there has been no material adverse change, nor any
     development or event involving a prospective material adverse change, in
     the financial condition, business, properties or results of operations of
     the Company and its subsidiaries taken as a whole, and, except as disclosed
     in or contemplated by the Offering Document, there has been no dividend or
     distribution of any kind declared, paid or made by the Company on any class
     of its capital stock.

          (u)  None of the Issuer, Holdings, the Company or any Subsidiary
     Guarantor is, and following the consummation of the Merger none of them
     will be, an open-end investment company, unit investment trust or face-
     amount certificate company that is or is required to be registered under
     Section 8 of the Investment Company Act of 1940 (the "Investment Company
     Act"); and none of the Issuer, Holdings, the Company or any Subsidiary
     Guarantor is and, after giving effect to the offering and sale of the
     Offered Securities, the Merger, the other Transactions and the application
     of the proceeds thereof as described in the Offering Document, none of them
     will be an "investment company" as defined in the Investment Company Act.

          (v)  No securities of the same class (within the meaning of Rule
     144A(d)(3) under the Securities Act) as the Offered Securities are listed
     on any national securities exchange registered under Section 6 of the
     Securities Exchange Act of 1934 ("Exchange Act") or quoted in a U.S.
     automated inter-dealer quotation system.

          (w)  Assuming the accuracy of the representations and the performance
     of the Initial Purchasers of their agreements contained herein, the offer
     and sale of the Offered Securities in the manner contemplated by this
     Agreement will be exempt from the registration requirements of the
     Securities Act by reason of Section 4(2) thereof and Regulation S
     thereunder.

          (x)  None of the Issuer, Holdings, the Company, nor any of their
     respective affiliates, nor any person acting on its or their behalf (i)
     has, within the six-month period prior to the date hereof, offered or sold
     in the United States or to any U.S. person (as such terms are defined in
     Regulation S under the Securities Act) the Offered Securities or any
     security of the same class or series as the Offered Securities or (ii) has
     offered or will offer or sell the Offered Securities (A) in the United
     States by means of any form of general solicitation or general advertising

     5.  Certain Agreements of the Issuer and Holdings.  The Issuer and Holdings
agree with the Initial Purchasers that:

          (a)  The Issuer will advise CSFBC promptly of any proposal to amend or
     supplement the Offering Document and will not effect such amendment or
     supplementation without CSFBC's consent, which consent shall not be
     unreasonably withheld or delayed. If, at any time prior to the completion
     of the resale of the Offered Securities by any Initial Purchaser, any event
     occurs as a result of which the Offering Document as then amended or
     supplemented would include an untrue statement of a material fact or omit
     to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading, the Issuer promptly will notify CSFBC of such event and
     promptly will prepare, at its own expense, an amendment or supplement which
     will correct such statement or omission. Neither the CSFBC'S consent to,
     nor its delivery to offerees or investors of, any such amendment or
     supplement shall constitute a waiver of any of the conditions set forth in
     Section 6.

          (b)  The Issuer will furnish to the CSFBC copies of any Offering
     Document and all amendments and supplements to any such document, in each
     case as soon as available and in such quantities as CSFBC reasonably
     requests, and the Issuer will furnish to CSFBC on the date hereof three
     copies of the Offering Circular signed by a duly authorized officer of the
     Company, one of which will include the independent accountants' reports
     therein manually signed by such independent accountants. At any time when
     the Issuer is not subject to Section 13 or 15(d) of the Exchange Act, the
     Issuer will promptly furnish or cause to be furnished to CSFBC and, upon
     request of holders and prospective purchasers of the Offered Securities, to
     such holders and purchasers, copies of the additional information required
     to be delivered to holders and prospective purchasers of the Offered
     Securities pursuant to Rule 144A(d)(4) under the Securities Act (or any
     successor provision thereto) in order to permit compliance with Rule 144A
     in connection with resales by such holders of the Offered Securities (the
     "Additional Issuer Information"). The Issuer will pay the expenses of
     printing and distributing to the Initial Purchasers all such documents.

          (c)  The Issuer will arrange for the qualification of the Offered
     Securities for sale and the determination of their eligibility for
     investment under the laws of such jurisdictions in the United States and
     Canada as CSFBC designates and will continue such qualifications in effect
     so long as required for the resale of the Offered Securities by the Initial
     Purchasers; provided, however, that the
                 --------  -------

                                       9

     Issuer will not be required to qualify as a foreign corporation or to file
     a general consent to service of process or to subject itself to taxation in
     respect of doing business in any such state or province where it is not
     then required to be so qualified or subject to taxation.

          (d)  During the period of three years hereafter, the Issuer or the
     Company will furnish to CSFBC, and upon request, to each of the other
     Initial Purchasers, as soon as practicable after the end of each fiscal
     year, a copy of its annual report to shareholders for such year; and the
     Issuer or the Company will furnish to the CSFBC, and upon request, to each
     of the other Initial Purchasers as soon as available, a copy of each report
     and any definitive proxy statement of it filed with the Commission under
     the Exchange Act or mailed to holders of Offered Securities or of any
     securities of the Issuer or the Company which have been registered under
     Section 12 of the Exchange Act.

          (e)  During the period of two years after the Closing Date, the Issuer
     will, upon request, furnish to CSFBC, and upon request, furnish to any
     holder of Offered Securities, a copy of the restrictions on transfer
     applicable to the Offered Securities.

          (f)  During the period of two years after the Closing Date, none of
     the Issuer, Holdings, the Company or any of the Subsidiary Guarantors will,
     and none of them will permit any of their affiliates (as defined in Rule
     144 under the Securities Act) to, resell any of the Offered Securities that
     have been reacquired by any of them.

          (g)  During the period of two years after the Closing Date, none of
     the Issuer, Holdings, the Company or any of the Subsidiary Guarantors will
     become, an open-end investment company, unit investment trust or face-
     amount certificate company that is or is required to be registered under
     Section 8 of the Investment Company Act.

          (h)  The Issuer or Holdings will pay all expenses incidental to the
     performance of the obligations of the Issuer, Holdings, the Company and the
     Company's subsidiaries under this Agreement (including the counterparts to
     be executed concurrently with the consummation of the Merger), the
     Indenture, the Supplemental Indenture, the Registration Rights Agreement
     (including the counterparts to be executed concurrently with the
     consummation of the Merger) and the other Transaction Documents, including
     (i) the fees and expenses of counsel and accountant for the Issuer,
     Holdings, the Company and the Subsidiary Guarantors and of the Trustee and
     its professional advisers; (ii) all expenses in connection with the
     execution, issue, authentication, packaging and initial delivery of the
     Offered Securities and, as applicable, the Exchange Securities, and the
     printing of the Offering Document and amendments and supplements thereto,
     and any other document relating to the issuance, offer, sale and delivery
     of the Offered Securities and as applicable, the Exchange Securities; (iii)
     the cost of listing the Offered Securities and qualifying the Offered
     Securities for trading in The Portal/SM/ Market ("PORTAL") and any expenses
     incidental thereto; (iv) the cost of any advertising approved by the Issuer
     in connection with the issue of the Offered Securities; (v) for any
     expenses (including reasonable fees and disbursements of counsel to the
     Initial Purchasers) incurred in connection with qualification of the
     Offered Securities or the Exchange Securities for sale under the laws of
     such jurisdictions as CSFBC designates and the printing of memoranda
     relating thereto (such expenses not to exceed $15,000); (vi) for any fees
     charged by investment rating agencies for the rating of the Offered
     Securities or the Exchange Securities; and (vii) for expenses incurred in
     printing and distributing any Offering Document (including any amendments
     and supplements thereto) to or at the direction of the Initial Purchasers.
     Each party will pay its own expenses in connection with attending or
     hosting meetings with prospective purchasers of the Offered Securities from
     the Initial Purchasers, including the costs attributable to the use of a
     private airplane to attend such meetings to the extent one is so used.

                                       10

          (i)  In connection with the offering, until CSFBC shall have notified
     the Issuer of the completion of the resale of the Offered Securities, none
     of the Issuer, Holdings, the Company, any of the Subsidiary Guarantors or
     any of their respective affiliates has or will, either alone or with one or
     more other persons, bid for or purchase for any account in which it or any
     of its affiliates has a beneficial interest any Offered Securities or
     attempt to induce any person to purchase any Offered Securities; and none
     of them nor any of their affiliates will make bids or purchases for the
     purpose of creating actual, or apparent, active trading in, or of raising
     the price of, the Offered Securities.

          (j)  For a period of 120 days after the date of the initial offering
     of the Offered Securities by the Initial Purchasers, except as described in
     the section entitled "The Transactions" in the Offering Document, none of
     the Issuer, Holdings, the Company or any of the Company's subsidiaries will
     offer, sell, contract to sell, pledge or otherwise dispose of, directly or
     indirectly, any United States dollar-denominated debt securities issued or
     guaranteed by any of the Issuer, Holdings, the Company or any of the
     Company's subsidiaries and having a maturity of more than one year from the
     date of issue.  The Issuer, Holdings, the Company or any of the Company's
     subsidiaries will not at any time offer, sell, contract to sell, pledge or
     otherwise dispose of, directly or indirectly, any securities under
     circumstances where such offer, sale, pledge, contract or disposition would
     cause the exemption afforded by Section 4(2) of the Securities Act or the
     safe harbor of Regulation S thereunder to cease to be applicable to the
     offer and sale of the Offered Securities.

          (k)  On the Closing Date, the Issuer will deposit the Escrowed Funds
     with the Escrow Agent.

          (l)  The Issuer, Holdings and the Company  will use the net proceeds

          (m)  None of the Issuer, Holdings, the Company,  or any of the
     Company's subsidiaries will sell, offer for sale or solicit offers to buy
     or otherwise negotiate in respect of any security (as defined in the
     Securities Act) that would be integrated with the sale of the Offered
     Securities in a manner that would require the registration under the
     Securities Act of the sale to the Initial Purchasers of the Offered
     Securities or to take any other action that would result in the resale of
     the Offered Securities not being exempt from registration under the
     Securities Act.

          (n)  None of the Issuer, Holdings, the Company or any of its
     subsidiaries, will take, directly or indirectly, any action designed to, or
     that might reasonably be expected to, cause or result in stabilization or
     manipulation of the price of any security of the Issuer to facilitate the
     resale of the Offered Securities.  Except as permitted by the Securities
     Act, the Issuer will not distribute any (i) preliminary offering memorandum
     or offering memorandum, including without limitation, the Offering Document

     shall not have occurred (i) a change in U.S. or international financial,

     respect of dealings in the secondary market, or (ii) (A) any change, or any
     development or event involving a prospective change, in the financial
     condition, business, properties or results of operations of the Company or

     Securities; (B) any downgrading in the rating of any debt securities of the
     Company by any "nationally recognized statistical rating organization" (as

     sale of and payment for the Offered Securities.

          (c)  There shall exist at and as of the Closing Date no condition that
     would constitute a default (or an event that with notice or lapse of time,

Preliminary Offering Circular, the indemnity agreement contained in this
subsection (a) shall not inure to the benefit of the Initial Purchaser that sold
the securities concerned (or any Person controlling such Purchaser) to the
person asserting any such losses, claims, damages or liabilities, to the extent
that such sale was an initial resale by such Initial Purchaser and any such
loss, claim, damage or liability of such Initial Purchaser or such Person
controlling such Initial Purchaser results from the fact that there was not sent
or given to the person, at or prior to the written confirmation of the sale of
such securities to such person, a copy of the Offering Circular, if the Issuer
or the Company had previously furnished copies thereof to such Initial Purchaser
on a timely basis and in a sufficient quantity to enable such Initial Purchaser
to furnish copies of the Offering Circular to all the persons to whom such
Initial Purchaser sold the securities concerned.

     (b)  The Initial Purchasers will indemnify and hold harmless the Issuer,
its directors and officers and each person, if any, who controls the Issuer
within the meaning of Section 15 of the Securities Act, against any losses,
claims, damages or liabilities to which the Issuer may become subject, under the
Securities Act or the Exchange Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in the Offering Document or any amendment or supplement thereto or
arise out of or are based upon the omission or the alleged omission to state
therein a material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Issuer or the
Company by such Initial Purchasers through CSFBC specifically for use therein,
and will reimburse any legal or other expenses reasonably incurred by the Issuer
in connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred, it being understood and
agreed that the only such information furnished by the Initial Purchasers
consists of (i) the following information in the Offering Document: under the
caption "Plan of Distribution", the fifth, eighth and ninth paragraphs, and the
third sentence of the seventh paragraph; provided, however, that the Initial
                                         --------  -------
Purchasers shall not be liable for any losses, claims, damages or liabilities
arising out of or based upon the Issuer's failure to perform its obligations
under Section 5(a) of this Agreement.

     (c)  Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any

                                       14
<PAGE>

indemnified party otherwise than under subsection (a) or (b) above. In case any
such action is brought against any indemnified party and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under this
Section for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action and does not include a statement as to or an admission of fault,
culpability or failure to act by or on behalf of any indemnified party.

     (d)  If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Issuer and
Holdings on the one hand and the Initial Purchasers on the other from the
offering of the Offered Securities or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Issuer and Holdings on the one hand and
the Initial Purchasers on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities as well
as any other relevant equitable considerations.  The relative benefits received
by the Issuer and Holdings on the one hand and the Initial Purchasers on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Issuer bear to the
total discounts and commissions received by the Initial Purchasers from the
Issuer under this Agreement.  The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Issuer and Holdings or the Initial
Purchasers and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission.  The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities referred to in the first sentence of this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim which is the subject of this subsection (d). Notwithstanding the
provisions of this subsection (d),  the Initial Purchasers shall not be required
to contribute any amount in excess of the amount by which the total discounts
and commissions received by the Initial Purchasers exceeds the amount of any
damages which the Initial Purchasers have otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.

     (e)  The obligations of the Issuer and Holdings under this Section shall be
in addition to any liability which the Issuer and Holdings may otherwise have
and shall extend, upon the same terms and conditions, to each person, if any,
who controls such Initial Purchaser within the meaning of the Securities Act or
the Exchange Act; and the obligations of the Initial Purchasers under this
Section shall be in addition to any liability which the Initial Purchasers may
otherwise have and shall extend, upon the same terms and conditions, to each
person, if any, who controls the Issuer within the meaning of the Securities Act
or the Exchange Act.

     8.  Default of Initial Purchasers.  If any Initial Purchaser or Initial
Purchasers default in their obligations to purchase Offered Securities hereunder
and the aggregate principal amount of Offered Securities that such defaulting
Initial Purchaser or Initial Purchasers agreed but failed to purchase does not
exceed 10% of the total principal amount of Offered Securities, CSFBC may make
arrangements satisfactory to the Issuer

                                       15
<PAGE>

for the purchase of such Offered Securities by other persons, including any of
the Initial Purchasers, but if no such arrangements are made by the Closing
Date, the non-defaulting Initial Purchasers shall be obligated severally, in
proportion to their respective commitments hereunder, to purchase the Offered
Securities that such defaulting Initial Purchasers agreed but failed to
purchase. If any Initial Purchaser or Initial Purchasers so default and the
aggregate principal amount of Offered Securities with respect to which such
default or defaults occur exceeds 10% of the total principal amount of Offered
Securities and arrangements satisfactory to CSFBC and the Issuer for the
purchase of such Offered Securities by other persons are not made within 36
hours after such default, this Agreement will terminate without liability on the
part of any non-defaulting Initial Purchaser or the Issuer, except as provided
in Section 9. As used in this Agreement, the term "Initial Purchaser" includes
any person substituted for an Initial Purchaser under this Section. Nothing
herein will relieve a defaulting Initial Purchaser from liability for its
default.

     9.  Survival of Certain Representations and Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of the
Issuer and Holdings or any of their officers and of the Initial Purchasers set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation, or statement as to the results thereof,
made by or on behalf of the Initial Purchasers, the Issuer,  Holdings or any of
their respective representatives, officers or directors or any controlling
person, and will survive delivery of and payment for the Offered Securities.  If
for any reason the purchase of the Offered Securities by the Initial Purchasers
is not consummated, the Issuer shall remain responsible for the expenses to be
paid or reimbursed by it pursuant to Section 5(h) and the respective obligations
of the Issuer and Holdings and the Initial Purchasers pursuant to Section 7
shall remain in effect.  If the purchase of the Offered Securities by the
Initial Purchasers is not consummated for any reason other than solely because
of the occurrence of any event specified in clause (C), (D) or (E) of Section
6(b)(ii), the Issuer and Holdings will reimburse the Initial Purchasers for all
out-of-pocket expenses (including fees and disbursements of counsel) reasonably
incurred by it in connection with the offering of the Offered Securities;
provided, however, that the Issuer and Holdings will not reimburse the
--------  -------
defaulting Initial Purchaser or Purchasers if the purchase is not consummated as
a result of the termination of this Agreement pursuant to Section 8.

     10.  Notices.  All communications hereunder will be in writing and, if sent
to the Initial Purchasers will be mailed, delivered or telegraphed and confirmed
to the Initial Purchasers at Eleven Madison Avenue, New York, New York 10010-
3629, Attention:  Investment Banking Department - Transactions Advisory Group,
or, if sent to the Issuer, will be mailed, delivered or telegraphed and
confirmed to it at BLUM CB Corp., 909 Montgomery Street, Suite 400, San
Francisco, California 94133, Attention:  Claus Moller.

     11.  Successors.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
controlling persons referred to in Section 7, and no other person will have any
right or obligation hereunder, except that holders of Offered Securities shall
be entitled to enforce the agreements for their benefit contained in the second
and third sentences of Section 5(b) hereof against the Issuer as if such holders
were parties thereto.

     12.  Representation of Initial Purchasers.  CSFBC will act for the several
Initial Purchasers in connection with this purchase, and any action under this
Agreement taken by CSFBC will be binding upon all the Initial Purchasers.

     13.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

     14.  Applicable Law.  This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York.

Ladies and Gentlemen:

          We have acted as special counsel to BLUM CB Corp. (the "Issuer"), a
Delaware corporation, and CBRE Holding, Inc. ("Holdings"), a Delaware
corporation and the parent corporation of the Issuer, in connection with the
purchase by you of $229,000,000 aggregate principal amount of 11 1/4% Senior
Subordinated Notes due 2011 (the "Notes") of the Issuer, unconditionally
guaranteed on an unsecured, senior subordinated basis by Holdings (such guaranty
is referred to herein as the "Parent Guaranty"), pursuant to the Purchase
Agreement, dated as of May 31, 2001 (the "Purchase Agreement"), by and among the
Issuer, Holdings and you, as the initial purchasers (the "Initial Purchasers").

          Pursuant to the terms and subject to the conditions of the amended and
restated agreement and plan of merger, dated as of May 31, 2001, among CB
Richards Ellis Services, Inc. (the "Company"), a Delaware corporation, Holdings
and the Issuer, the Issuer is to be merged into the Company as described
therein.

          We have examined the Offering Circular, dated as of May 31, 2001 (the
"Offering Circular"), relating to the sale of the Notes; the Indenture, dated as
of June 7, 2001 (the "Indenture"), by and among the Issuer, Holdings and State
Street Bank and Trust Company of California, N.A., as trustee (the "Trustee"),
relating to the Notes and the Parent Guaranty; the global notes representing the
Notes; the Purchase Agreement; the Escrow Agreement, dated as of June 7, 2001
(the "Escrow Agreement"), by and
<PAGE>

Credit Suisse First Boston Corporation                                         2

among the Issuer, Holdings and State Street Bank and Trust Company N.A., as
escrow agent (the "Escrow Agent"); and the Registration Rights Agreement, dated
as of May 31, 2001 (the "Registration Rights Agreement"), by and among the
Issuer, Holdings and you. In addition, we have examined, and have relied as to
matters of fact upon, the documents delivered to you at the closing, and upon
originals, or duplicates or certified or conformed copies, of such corporate
records, agreements, documents and other instruments and such certificates or
comparable documents of public officials and of officers and representatives of
the Issuer, Holdings and the Company, and have made such other investigations,
as we have deemed relevant and necessary in connection with the opinions
hereinafter set forth.

          In such examination, we have assumed the genuineness of all
signatures, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as duplicates or certified or conformed copies,
and the authenticity of the originals of such latter documents.

          Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that:

          1.  The Issuer and Holdings have been duly incorporated and are
     validly existing and in good standing as corporations under the laws of the
     State of Delaware.

          2.  The Indenture has been duly authorized, executed and delivered by
     the Issuer and Holdings and, assuming that the Indenture is the valid and
     legally binding obligation of the Trustee, constitutes valid and legally
     binding obligations of the Issuer and Holdings, respectively, enforceable
     against the Issuer and Holdings in accordance with its terms.

          3.  The Notes have been duly authorized, executed and issued by the
     Issuer and, assuming due authentication thereof by the Trustee and upon
     payment and delivery in accordance with the Purchase Agreement, will
     constitute valid and binding obligations of the Issuer enforceable against
     the Issuer in accordance with their terms and entitled to the benefits of
     the Indenture

          4.  The Exchange Securities (as defined in the Registration Rights
     Agreement) have been duly authorized by the Issuer and Holdings.

          5.  The Parent Guaranty has been duly authorized, executed and issued
     by Holdings and, assuming due authentication of the Notes by the Trustee
     and upon payment for and delivery of the Notes in accordance with the
     Purchase Agreement, will constitute valid and legally binding obligation of
     Holdings enforceable against Holdings in accordance with its terms and
     entitled to the benefits of the Indenture.

          6.  The Registration Rights Agreement has been duly authorized,
     executed and delivered by the Issuer and Holdings and, assuming that the
     Registration Rights Agreement is the valid and legally binding obligations
     of the Initial Purchasers, constitutes valid and legally binding
     obligations of the Issuer and Holdings, respectively, enforceable against
     the Issuer and Holdings in accordance with its terms.

          7.  The Escrow Agreement has been duly authorized executed and
     delivered by the Issuer and Holdings and, assuming that the Escrow
     Agreement is the valid and legally binding obligation of the Escrow Agent,
     constitutes valid and legally binding obligations of the Issuer and
     Holdings, respectively, enforceable against the Issuer and Holdings in
     accordance with its terms.

          8.  The Purchase Agreement has been duly authorized and executed by
     the Issuer and Holdings.

          9.  The statements made in the Offering Circular under the caption
     "Description of the Notes" insofar as they purport to constitute summaries
     of certain terms of documents referred to therein, constitute accurate
     summaries of the terms of such documents in all material respects.

          10.  The statements made in the Offering Circular under the caption
     "U.S. Federal Income Tax Consequences to Non-U.S. Holders" insofar as they
     purport to constitute summaries of matters of United States federal tax law
     and regulations or legal conclusions with respect thereto, constitute
     accurate summaries of the matters described therein in all material
     respects.

          11.  The issue and sale of the Notes by the Issuer, the issue of the
     Parent Guaranty by Holdings, the compliance by the Issuer and Holdings with
     all of the provisions of the Purchase Agreement and the consummation of the
     Merger (as defined in the Indenture) will not breach or result in a default
     under any of the agreements or instruments identified on Schedule I annexed
     hereto and furnished to us by the Issuer and Holdings, nor will such action
     violate the Certificate of Incorporation or By-laws of the Issuer or
     Holdings or any federal or New York statute or the Delaware General
     Corporation Law or any order known to us issued pursuant to any federal or
     New York statute or the Delaware General Corporation Law by any court or
     governmental agency or body or court having jurisdiction over the Issuer,
     Holdings or any of their respective property.

          12.  No consent, approval, authorization, order, registration or
     qualification of or with any federal or New York governmental agency or
     body or any Delaware governmental agency or body acting pursuant to the
     Delaware General Corporation Law or, to our knowledge, any federal or New
     York court or any Delaware court acting pursuant to the Delaware General
     Corporation Law is required for the issue and sale of the Notes by the
     Issuer and the issue of the Parent Guaranty by Holdings and the compliance
     by the Issuer and Holdings with all of the provisions of the Purchase
     Agreement, except for such consents, approvals, authorizations,
     registrations or qualifications as may be required under state securities
     or Blue Sky laws in connection with the purchase and distribution of the
     Notes by the Initial Purchasers.

          13.  To our knowledge, there are no pending or threatened legal
     proceedings to which the Issuer or Holdings is a party or otherwise subject
     that are required to be described in the Offering Circular which are not
     described as required.

          14.  No registration under the Securities Act of 1933, as amended (the
     "Securities Act"), of the Notes or the Parent Guaranty and no qualification
     of the Indenture under the Trust Indenture Act is required for the offer
     and sale of the Notes by the Issuer to the Initial Purchasers or the
     reoffer and resale of the Notes by the Initial Purchasers to the initial
     purchasers therefrom
<PAGE>

Credit Suisse First Boston Corporation                                         4

     solely in the manner contemplated in the Offering Circular, the Purchase
     Agreement and the Indenture.

          15.  Following the issuance of the Notes and the application of the
     proceeds therefrom, none of the Issuer, Holdings or the Company will be an
     "investment company" within the meaning of and subject to regulation under
     the Investment Company Act of 1940, as amended.

          16.  When the Notes are issued and delivered pursuant to the Purchase
     Agreement, such Notes will not be of the same class (within the meaning of
     Rule 144A under the Securities Act) as securities of the Company that are
     listed on a national securities exchange registered under Section 6 of the
     Securities Exchange Act of 1934, as amended, or that are quoted in a United
     States automated inter-dealer quotation system.

          Our opinions in paragraphs 2, 3, 5, 6 and 7 above are subject to (i)
the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, (ii) general equitable principles (whether considered in a proceeding
in equity or at law) and (iii) an implied covenant of good faith and fair
dealing.  Our opinion in paragraph 6 is further limited by considerations of
public policy.

          We express no opinion as to the validity, legally binding effect or
enforceability of any provision of the Registration Rights Agreement or any
related provisions of the Indenture, that requires or relates to payment of any
interest at a rate or in an amount which a court would determine in the
circumstances under applicable law to be commercially unreasonable or a penalty
or a forfeiture.

          We have not independently verified the accuracy, completeness or
fairness of the statements made or included in the Offering Circular and take no
responsibility therefore, except as and to the extent set forth in paragraphs 9
and 10 above.  In the course of the preparation by the Issuer, Holdings and the
Company of the Offering Circular, we participated in conferences with certain
officers and employees of the Issuer, Holdings and the Company and with
representatives of Arthur Andersen LLP, independent accountants to the Issuer,
Holdings and the Company.  Based upon our examination of the Offering Circular,
our investigations made in connection with the preparation of the Offering
Circular and our participation in the conferences referred to above, we have no
reason to believe that the Offering Circular contains any untrue statement of a
material fact or omits to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not

misleading, except that we express no belief with respect to the financial
statements or other financial or statistical data contained in the Offering
Circular.

          We are members of the Bar of the State of New York, and we do not
express any opinion herein concerning any law other than the law of the State of

Ladies and Gentlemen:

          Reference is hereby made to the purchase by you of $229,000,000
aggregate principal amount of 11 1/4% Senior Subordinated Notes due 2011 (the
"Notes") of BLUM CB Corp. (the "Issuer"), a Delaware corporation,
unconditionally guaranteed on an unsecured, senior subordinated basis by CBRE
Holding, Inc. ("Holdings"), a Delaware corporation and the parent corporation of
the Issuer (such guaranty is referred to herein as the "Parent Guaranty"), and
to be unconditionally guaranteed on an unsecured, senior subordinated basis by
the subsidiaries listed on Schedule I hereto (such listed subsidiaries are
referred to herein as the "Subsidiary Guarantors") of CB Richard Ellis Services,
Inc. (the "Company"), a Delaware corporation and the entity into which the
Issuer will merge (pursuant to the terms and subject to the conditions of the
amended and restated agreement and plan of merger, dated as of May 31, 2001,
among the Company, Holdings and the Issuer), pursuant to the Purchase Agreement,
dated as of May 31, 2001 (the "Purchase Agreement"), by and among the Issuer,
Holdings and you, as the initial purchasers (the "Initial Purchasers").

          As the General Counsel of the Company, I have examined the Offering
Circular, dated as of May 31, 2001 (the "Offering Circular"), relating to the
sale of the Notes; the Indenture, dated as of June 7, 2001 (the "Indenture"), by
and among the Issuer, Holdings and State Street Bank and Trust Company of
California, N.A., as trustee (the "Trustee"), relating to the Notes and the
Parent Guaranty; the global notes

representing the Notes; the Purchase Agreement; the Escrow Agreement, dated as
of June 7, 2001 (the "Escrow Agreement"), by and among the Issuer, Holdings and
State Street Bank and Trust Company N.A., as escrow agent; and the Registration
Rights Agreement, dated as of May 31, 2001 (the "Registration Rights
Agreement"), by and among the Issuer, Holdings and the Initial Purchasers. In
addition I have examined, and have relied as to matters of fact upon, the
documents delivered to you at the closing, and upon originals, or duplicates or
certified or conformed copies, of such corporate records, agreements, documents
and other instruments and such certificates or comparable documents of public
officials and of officers and representatives of the Company and the Subsidiary
Guarantors, and have made such other investigations, as I have deemed relevant
and necessary in connection with the opinions hereinafter set forth.

          In such examination, I have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as duplicates or certified or conformed copies, and
the authenticity of the originals of such latter documents.

          Based upon the foregoing, and subject to the qualifications and
limitations stated herein, I am of the opinion that:

          1.  Each of the Company and the Subsidiary Guarantors is duly
     incorporated and is validly existing as a corporation in good standing
     under the laws of the jurisdiction of its incorporation, with corporate
     power and authority to own its properties and conduct its business as
     described in the Offering Circular; and each of the Company and the
     Subsidiary Guarantors is duly qualified to do business as a foreign
     corporation in good standing in all jurisdictions in which its ownership or
     leasing of properties or the conduct of its business requires such
     qualification; except to the extent that the failure to be so qualified or
     to be in good standing would not have a material adverse effect on the
     business, financial condition or results of operation of the Company and
     its subsidiaries, taken as a whole ("Material Adverse Effect").

          2.  Neither the Company nor, to my knowledge, any of the Subsidiary
     Guarantors is in breach or violation of any of the terms and provisions of,
     or in default under, (i) any statute, rule or regulation, or any order
     known to me of any governmental agency or body or any court, domestic or
     foreign, that has jurisdiction over the Company or any of its subsidiaries
     or any of their properties, (ii) any agreement or instrument to which the
     Company or any of the Subsidiary Guarantors is a party or by which the
     Company or any of the Subsidiary Guarantors is bound or to which any of the
     properties of the Company or its subsidiaries is subject or (iii) the
     charter, by-laws or similar governing document of the Company or any of the
     Subsidiary Guarantors,
<PAGE>

Credit Suisse First Boston Corporation                                         3


     except for such breaches, violations or defaults which would not result in
     a Material Adverse Effect.

          3.  Except as disclosed in the Offering Circular, there are no pending
     or threatened actions, suits or proceedings against the Company or, to my
     knowledge, any Subsidiary Guarantor or any of their respective properties
     or assets that, if determined adversely to the Company or any such
     Subsidiary Guarantor, would individually or in the aggregate have a
     Material Adverse Effect, or would materially and adversely affect the power
     or ability of the Company or any Subsidiary Guarantor to consummate the
     Transactions (as defined in the Purchase Agreement) or would materially and
     adversely affect the ability of the Company to assume the Issuer's
     obligations under the Purchase Agreement, the Registration Rights
     Agreement, the Notes or the Indenture or the Subsidiary Guarantors' ability
     to guarantee the Notes or to execute the Supplemental Indenture or the
     counterparts to the Purchase Agreement or the Registration Rights
     Agreement.

          4.  Except as otherwise disclosed in the Offering Circular, the
     consummation of the Transactions will not result in a breach or violation
     of any of the terms and provisions, of, or constitute a default under, any
     statute, rule or regulation, or any order known to me of any governmental
     agency or body or any court having jurisdiction over the Company or, to my
     knowledge, any Subsidiary Guarantor or any of the properties of the Company
     or any of the properties of the Subsidiary Guarantors known to me, or any
     agreement or instrument which the Company or, to my knowledge, a Subsidiary
     Guarantor is a party or by which the Company or, to my knowledge, a
     Subsidiary Guarantor is bound or to which any of the properties of the
     Company or, to my knowledge, a Subsidiary Guarantor is subject, or the
     charter or by-laws of the Company or any Subsidiary Guarantor.

          I have not independently verified the accuracy, completeness or
fairness of the statements made or included in the Offering Circular and take no
responsibility therefor.  Based upon my examination of the Offering Circular, I
have no reason to believe that the Offering Circular contains any untrue
statement of a material fact or omits to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, except that I shall express no belief with
respect to the financial statements or other financial or statistical data
contained in the Offering Circular.

          I am a member of the Bar of the State of California, and I do not
express any opinion herein concerning any law other than the law of the State of
California, the federal law of the United States, the Delaware General
Corporation law and the Delaware Limited Liability Company Act.

Ladies and Gentlemen:

We have acted as special counsel to BLUM CB Corp. (the "Issuer"), a Delaware
Corporation, CBRE Holding, Inc. ("Holdings"), a Delaware corporation and the
parent corporation of the Issuer, CB Richard Ellis Services, Inc. (the
"Company"), a Delaware corporation, and the Subsidiary Guarantors (as defined
below) in connection with the purchase by you of $229,000,000 aggregate
principal amount of 11 1/4% Senior Subordinated Notes due 2011 (the "Notes") of
the Issuer, unconditionally guaranteed on an unsecured, senior subordinated
basis by (i) Holdings and (ii) the subsidiaries of the Company listed on
Schedule I hereto (such listed subsidiaries are referred to herein as the
"Subsidiary Guarantors").  Such guarantees of the Subsidiary Guarantors are
referred to herein as the "Subsidiary Guarantees."  Pursuant to the terms of the
amended and restated plan of merger, dated as of May 31, 2001, among the
Company, Holdings and the Issuer, the Issuer has been merged into the Company.

          We have examined the Indenture, dated as of June 7, 2001 (the
"Indenture"), by and among the Issuer, Holdings and State Street Bank and Trust
Company of California, N.A., as trustee (the "Trustee"); the Supplemental
Indenture, dated as of July ___, 2001 (the "Supplemental Indenture"), by and
among Holdings, the Company, the Subsidiary Guarantors and the Trustee; the
global notes representing the Notes; the counterpart (the "Purchase Agreement
Counterpart") to the Purchase Agreement, dated May 31, 2001, by and among the
Issuer, Holdings and you, as initial purchasers (the "Initial Purchasers"); and
the counterpart (the "Registration Rights Agreement Counterpart") to the
Registration Rights Agreement, dated May

31, 2001, by and among the Issuer, Holdings and the Initial Purchasers. In
addition, we have examined, and have relied as to matters of fact upon, the
documents delivered to you at the closing, and upon originals, or duplicates or
certified or conformed copies, of such corporate records, agreements, documents
and other instruments and such certificates or comparable documents of public
officials and of officers and representatives of the Issuer, the Company,
Holdings and the Subsidiary Guarantors, and have made such other investigations,
as we have deemed relevant and necessary in connection with the opinions
hereinafter set forth.

          In such examination, we have assumed the genuineness of all
signatures, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as duplicates or certified or conformed copies,
and the authenticity of the originals of such latter documents.

          In rendering the opinions set forth in the enumerated paragraphs
below, we have assumed that (1) the Subsidiary Guarantors that are not
incorporated in, or organized or formed under the laws of, the State of Delaware
(such guarantors, the "Non-Delaware Guarantors") are validly existing and in
good standing under the laws of the jurisdictions in which each of them is
organized and have duly authorized, executed and delivered the Subsidiary
Guarantees of the Non-Delaware Guarantors in accordance with their respective
charter documents and by-laws (or, as the case may be, equivalent constitutive
documents) and the laws of the jurisdictions in which each of them is organized,
(2) execution, delivery and performance by the Non-Delaware Guarantors of the
Guarantees of the Non-Delaware Guarantors do not violate the laws of the
jurisdictions in which each of them is incorporated, organized or formed and (3)
execution, delivery and performance by the Non-Delaware Guarantors of the
Guarantees of the Non-Delaware Guarantors do not constitute a breach or
violation of any agreement or instrument that is binding upon the Non-Delaware
Guarantors.

          Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that:

          1.  The Supplemental Indenture has been duly authorized, executed and
     delivered by Holdings, the Company and the Subsidiary Guarantors and,
     assuming that the Supplemental Indenture is the valid and legally binding
     obligation of the Trustee, the Supplemental Indenture constitutes valid and
     legally binding obligations of Holdings, the Company and the Subsidiary
     Guarantors, respectively, enforceable against Holdings, the Company and the
     Subsidiary Guarantors in accordance with its terms.

          2.  The Purchase Agreement Counterpart and the Registration Rights
     Agreement Counterpart have been duly authorized, executed and delivered by
     the Company.

          3.  The Purchase Agreement Counterpart and the Registration Rights
     Agreement Counterpart have been duly authorized, executed and delivered by
     the Subsidiary Guarantors.

          4.  The Subsidiary Guarantees have been duly authorized, executed and
     issued by the Subsidiary Guarantors and, assuming due authentication of the
     Notes by the Trustee and upon payment for and delivery of the Notes in
     accordance with the Purchase Agreement, will constitute valid and legally
     binding obligations of the Subsidiary Guarantors enforceable against the
     Subsidiary Guarantors in accordance with their terms and entitled to the
     benefit of the Indenture.

          5.  The issue of the Subsidiary Guarantees by the Subsidiary
     Guarantors and the compliance by the Company and the Subsidiary Guarantors
     with all of the provisions of the Supplemental Indenture will not breach or
     result in a default under any of the agreements or instruments identified
     on Schedule II annexed hereto furnished to us by the Company, nor will such
     action violate the Certificate of Incorporation or By-laws of the Company
     or any Subsidiary Guarantor or any federal or New York statute or the
     Delaware General Corporation Law or any order known to us issued pursuant
     to any federal or New York statute or the Delaware General Corporation Law
     by any court or governmental agency or body or court having jurisdiction
     over the Company or any Subsidiary Guarantor or any of their properties.

          6.  No consent, approval, authorization, order, registration or
     qualification of or with any federal or New York governmental agency or
     body or any Delaware governmental agency or body acting pursuant to the
     Delaware General Corporation Law or, to our knowledge, any federal or New
     York court or any Delaware court acting pursuant to the Delaware General
     Corporation Law is required for the issue of the Subsidiary Guarantees by
     the Subsidiary Guarantors and the compliance by the Subsidiary Guarantors
     with all of the provisions of the Supplemental Indenture.

          Our opinion in paragraphs 1 and 4 above is subject to (i) the effects
of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, (ii)
general equitable principles (whether considered in a proceeding in equity or at
law) and (iii) an implied covenant of good faith and fair dealing.

          We express no opinion as to the validity, legally binding effect or
enforceability of any provision of the Supplemental Indenture, or the Guarantees
that requires or relates to payment of any interest at a rate or in an amount
which a court would determine in the circumstances under applicable law to be
