Dear Stockholder:
   
  You are cordially invited to attend the Annual Meeting of Stockholders of CB
Commercial Real Estate Services Group, Inc., a Delaware corporation ("CBC") to
be held on Thursday, August 28, 1997 at 8:00 A.M., Pacific time, at The
Sheraton Grande Hotel, 333 South Figueroa Street, Los Angeles, California.     
 
  The purpose of the meeting is to consider and act upon the following matters:
 
  1. The merger of a wholly-owned subsidiary of CBC with and into Koll Real
     Estate Services, a Delaware corporation ("KRES"). As a result of the
     merger, KRES would be a wholly-owned subsidiary of CBC but its stock
     would immediately after the merger be contributed to CB Commercial Real
     Estate Group, Inc. ("CBC Group"), the principal operating subsidiary of
     CBC. Stockholders will be asked to vote to approve the Agreement and
     Plan of Reorganization and related transactions, including the grant of
     stock options to four employees and one non-employee director of KRES in
     connection with their engagement as an employee or director of CBC, and
     the substitution of options ("CBC Options") to purchase shares of CBC
     Common Stock ("CBC Common") for options ("KRES Options") to purchase
     shares of KRES Common Stock ("KRES Common") previously issued to
     directors, employees or consultants of KRES or its subsidiaries as more
     fully set forth therein. The Agreement and Plan of Reorganization
     provides for the conversion of each share of KRES Common into
     (i) 0.776175 (subject to adjustment) shares of CBC Common and (ii) a
     number of warrants to purchase CBC Common (the "Warrants") equal to (A)
     600,000 divided by (B)(1) the number of shares of KRES Common
     outstanding immediately prior to the Effective Time plus (2) the number
     of shares of KRES Common which are subject to KRES Options outstanding
     and held by individuals who are directors, employees or consultants of
     KRES or certain of its subsidiaries immediately prior to the Effective
     Time (0.083238 Warrants per share of KRES Common based on an assumed
     aggregate of 7,208,243 shares of KRES Common outstanding and underlying
     such KRES options immediately prior to the Effective Time). Each Warrant
     shall be exercisable into one share of CBC Common at an exercise price
     of $30.00 per share of CBC Common. The number of shares of CBC Common
     issued in connection with the Merger will not exceed 5,614,261
     (including shares of CBC Common underlying CBC Options issued in
     exchange for KRES Options), and the number of shares into which the
     Warrants are exercisable will not exceed 600,000. The proposed merger
     requires regulatory approval and the approval and adoption of the
     Agreement and Plan of Reorganization by (i) the holders of a majority of
     the votes of CBC Common, Series A-1 Preferred Stock and Series A-2
     Preferred Stock of CBC, voting as a single class and (ii) the holders of
     a majority of the outstanding shares of KRES Common. KRES stockholders
     will consider approval and adoption of the Agreement and Plan of
     Reorganization at their separate meeting to be held on July 29, 1997.
 
  2. The election of nineteen (19) Directors to serve as such until the next
     Annual Meeting of Stockholders and until their successors are elected
     and qualified.
 
  3. The approval of CBC's 1997 Employee Stock Option Plan.
 
  4. The approval of CBC's 1998 Employee Stock Purchase Plan.
<PAGE>
 
  5. The approval of an amendment to CBC's 1991 Service Providers Stock
     Option Plan to clarify that options may be granted either at fair market
     value or, when an employee or independent contractor has given up the
     right to receive cash compensation, at an appropriate discount.
 
  6. The approval of CBC's 1996 Equity Incentive Plan.
 
  7. The ratification of the appointment of Arthur Andersen LLP as
     independent accountants for the Company for 1997.
 
  8. Such other matters as may properly come before the meeting and any
     adjournment thereof.
 
  The CBC Board of Directors believes that the merger and its related
transactions are in the best interests of CBC and its stockholders and
unanimously recommends that you vote FOR the approval and adoption of the
Agreement and Plan of Reorganization and the transactions contemplated thereby.
The enclosed Joint Proxy Statement/Prospectus explains in detail the proposed
merger. Please carefully review and consider all of this information.
 
  It is especially important that your shares be represented and voted at the
meeting. Although you may currently plan to attend the meeting, please
complete, sign, date and promptly return the enclosed proxy card. If you attend
the meeting and vote in person, your vote will supersede your proxy.

Dear Stockholder:
 
  You are cordially invited to attend a Special Meeting of Stockholders of
Koll Real Estate Services ("KRES") to be held on Wednesday, August 20, 1997 at
9:00 A.M., local time, at KRES' executive offices at 4343 Von Karman Avenue,
Newport Beach, California.
 
  The purpose of the meeting is to vote on the merger of KRES with and into a
wholly-owned subsidiary of CB Commercial Real Estate Services Group, Inc
("CBC"). As a result of this merger, KRES would be a wholly-owned subsidiary
of CBC but its stock would immediately after the merger be contributed to CB
Commercial Real Estate Group, Inc. ("CBC Group"), the principal operating
subsidiary of CBC. Stockholders will be asked to vote to approve the Agreement
and Plan of Reorganization and related transactions, including the grant of
stock options to four employees and one non-employee director of KRES in
connection with their engagement as an employee or director of CBC, and the
substitution of options ("CBC Options") to purchase shares of CBC Common Stock
("CBC Common") for options ("KRES Options") to purchase shares of KRES Common
Stock ("KRES Common") previously issued to directors, employees or consultants
of KRES or its subsidiaries as more fully set forth therein. The Agreement and
Plan of Reorganization provides for the conversion of each share of KRES
Common into (i) 0.776175 (subject to adjustment) shares of CBC Common and (ii)
a number of warrants to purchase CBC Common (the "Warrants") equal to
(A) 600,000 divided by (B)(1) the number of shares of KRES Common outstanding
immediately prior to the Effective Time plus (2) the number of shares of KRES
Common which are subject to KRES Options outstanding and held by individuals
who are directors, employees or consultants of KRES or certain of its
subsidiaries immediately prior to the Effective Time (0.083238 Warrants per
share of KRES Common based on an assumed aggregate of 7,208,243 shares of KRES
Common outstanding and underlying such KRES Options immediately prior to the
Effective Time). Each Warrant shall be exercisable into one share of CBC
Common at an exercise price of $30.00 per share of CBC Common. The number of
shares of CBC Common issued in connection with the Merger will not exceed
5,614,261 (including shares of CBC Common underlying CBC Options issued in
exchange for KRES Options) and the number of shares into which the Warrants
are exercisable will not exceed 600,000. The proposed merger requires
regulatory approval and the approval and adoption of the Agreement and Plan of
Reorganization by (i) the holders of a majority of the outstanding shares of
KRES Common and (ii) the holders of a majority of the votes of CBC Common
Stock, Series A-1 Preferred Stock and Series A-2 Preferred Stock of CBC,
voting as a single class.
   
  CBC stockholders will consider approval and adoption of the Agreement and
Plan of Reorganization at their separate meeting to be held on August 28,
1997.     
 
  The KRES Board of Directors believes that the merger and its related
transactions are in the best interests of KRES and its stockholders and
unanimously recommends that you vote FOR the approval and adoption of the
Agreement and Plan of Reorganization and the transactions contemplated
thereby. The enclosed Joint Proxy Statement/Prospectus explains in detail the
proposed merger and the transactions contemplated thereby. Please carefully
review and consider all of this information.
 
  It is especially important that your shares be represented and voted at the
meeting. Although you may currently plan to attend the meeting, please
complete, sign, date and promptly return the enclosed proxy card. If you
attend the meeting and vote in person, your vote will supersede your proxy.

                CB COMMERCIAL REAL ESTATE SERVICES GROUP, INC.
 
                                  PROSPECTUS
   
  This Joint Proxy Statement/Prospectus is being furnished to the stockholders
of CB Commercial Real Estate Services Group, Inc. ("CBC") and Koll Real Estate
Services ("KRES") in connection with the solicitation of proxies by the
respective Boards of Directors of CBC and KRES for use at the annual meeting
of stockholders of CBC to be held on August 28, 1997 and at a special meeting
of stockholders of KRES to be held on August 20, 1997, including in each case
any adjournments or postponements of the meetings. At the annual meeting of
CBC or any adjournments or postponements thereof, the stockholders of CBC
entitled to vote will be asked to consider and vote on the following
proposals:     
 
  1. To approve and adopt the Agreement and Plan of Reorganization (the
     "Merger Agreement") dated as of May 14, 1997 among CBC, KRES, CBC
     Acquisition Corporation, a Delaware corporation and wholly-owned
     subsidiary of CBC ("Acquisition Corporation") and certain stockholders
     of KRES, and the transactions contemplated thereby, including without
     limitation, the grant of new options to four employees and one non-
     employee director of KRES in connection with their engagement as an
     employee or director of CBC, and the substitution of options ("CBC
     Options") to purchase shares of CBC common stock, $.01 par value per
     share ("CBC Common") for options ("KRES Options") to purchase shares of
     KRES common stock, $.01 par value per share ("KRES Common") previously
     issued to directors, employees or consultants of KRES or its
     subsidiaries as more fully set forth herein (see "THE MERGER);"
 
  2. To elect nineteen (19) Directors to serve as such until the next Annual
     Meeting of Stockholders and until their successors are elected and
     qualified;
 
  3. To approve CBC's 1997 Employee Stock Option Plan;
 
  4. To approve CBC's 1998 Employee Stock Purchase Plan;
 
  5. To approve an amendment to CBC's 1991 Service Providers Stock Option
     Plan to clarify that options may be granted either at fair market value
     or, when an employee or independent contractor has given up the right to
     receive cash compensation, at an appropriate discount;
 
  6. To approve CBC's 1996 Equity Incentive Plan;
 
  7. To ratify the appointment of Arthur Andersen LLP as independent
     accountants for CBC for 1997; and
 
  8. To consider and act upon such other matters as may properly come before
     the meeting.
 
  At the special meeting of KRES, stockholders of KRES will be asked to
consider and vote on the proposal to approve and adopt the Merger Agreement
and the transactions contemplated thereby, including, without limitation, the
grant of stock options to four employees and one director of KRES, all of whom
will become employees or directors of CBC, and the substitution of options to
purchase shares of CBC Common for options to purchase shares of KRES Common
previously issued to directors, employees or consultants of KRES or its
subsidiaries as more fully set forth herein. See "THE MERGER."
 
  Pursuant to the Merger Agreement, KRES will be merged with and into
Acquisition Corporation (the "Merger"), with KRES being the surviving
corporation, and immediately after the Merger, CBC will contribute the shares
of KRES to CB Commercial Real Estate Group, Inc. ("CBC Group"), the principal
operating subsidiary of CBC. Upon consummation of the Merger, subject to
provisions for payment of cash for fractional shares, each share of KRES
Common issued and outstanding immediately prior to the effective time of the
<PAGE>
 
   
Merger (the "Effective Time") shall be converted into (i) 0.776175 of a share
of CBC Common, subject to adjustment as set forth below (the "Stock Exchange
Ratio") and (ii) a number of warrants to purchase CBC Common equal to (A)
600,000 divided by (B)(1) the number of shares of KRES Common outstanding
immediately prior to the effective time plus (2) the number of shares of KRES
Common which are subject to KRES options outstanding and held by individuals
who are directors, employees or consultants of KRES or certain of its
subsidiaries immediately prior to the Effective Time of the Merger (0.083238
warrants per share of KRES Common based on an assumed aggregate of 7,208,243
shares of KRES Common Stock outstanding and underlying such KRES Options
immediately prior to the Effective Time). For each $100,000 by which Bank
Indebtedness exceeds $47,375,000 or by which any subcategory of Bank
Indebtedness exceeds the applicable sublimit set forth in the Merger Agreement
(but without duplication), in both cases as of the Closing Date, the Stock
Exchange Ratio shall be reduced by 0.0005883. See "THE MERGER--Adjustments to
Merger Consideration." There is no floor limitation to such a reduction of the
Stock Exchange Ratio (i.e., in theory it may be reduced to zero). Each Warrant
shall be exercisable into one share of CBC Common at an exercise price of
$30.00 per share of CBC Common. The number of shares of CBC Common issued in
connection with the Merger will not exceed 5,614,261 (including shares of CBC
Common underlying CBC Options issued in exchange for KRES Options), and the
number of shares into which the Warrants are exercisable will not exceed
600,000. See "BACKGROUND AND REASONS FOR THE MERGER" for a description of the
factors considered in determining the Stock Exchange Ratio and the Warrant
Exchange Ratio. In addition, see the "Index of Defined Terms" beginning at
page 126 for the definitions of capitalized terms used in this Joint Proxy
Statement/Prospectus.     
   
  This Joint Proxy Statement/Prospectus and the accompanying forms of proxy
are first being mailed to stockholders of CBC and KRES on or about July 31,
1997.     
 
  This Joint Proxy Statement/Prospectus serves as a Prospectus of CBC under
the Securities Act of 1933, as amended (the "Securities Act"), for the
issuance of (1) up to 5,614,261 shares of CBC Common into which shares of KRES
Common will be converted upon consummation of the Merger and (2) warrants to
purchase up to 600,000 shares of CBC Common at an exercise price of $30 per
share which will be issued to stockholders of KRES in connection with the
Merger (the "Warrants"). Each Warrant becomes exercisable on the third
anniversary of the Effective Time and is exercisable at any time thereafter
until seven years from the Effective Time.
 
  CBC does not intend to apply to have the Warrants listed for quotation or
admitted for trading on the Nasdaq National Market or on any securities
exchange, central market system, over-the-counter market or similar system.
Accordingly, there will be no market for the Warrants. The CBC Common issued
in connection with the Merger will immediately be separately tradable. See
"DESCRIPTION OF CBC CAPITAL STOCK."
   
  On July 25, 1997, the closing price on the Nasdaq National Market of CBC
Common was $32.00.

   PROSPECTUS. THE PROPOSED  MERGER IS A  COMPLEX TRANSACTION. STOCKHOLDERS
    OF  CBC AND KRES  ARE STRONGLY  URGED TO  READ AND CONSIDER  CAREFULLY

                                    SUMMARY
 
  The following is a summary of certain of the information contained elsewhere
in the Joint Proxy Statement/Prospectus of CBC and KRES. Reference is made to,
and this summary is qualified in its entirety by, the more detailed information
contained elsewhere in this Joint Proxy Statement/Prospectus, the Annexes
hereto, and in the documents incorporated herein by reference, which contain
further information, some of which is not summarized below. Stockholders of CBC

THE MEETINGS
   
  The CBC Annual Meeting of Stockholders (the "CBC Meeting") will be held on
August 28, 1997 at 8:00 A.M., Pacific time, at The Sheraton Grande Hotel, 333
South Figueroa Street, Los Angeles, California. The KRES Special Meeting of
Stockholders (the "KRES Meeting," and together with the CBC Meeting, the
"Meetings") will be held on August 20, 1997 at 9:00 A.M., Pacific time, at
KRES' executive offices at 4343 Von Karman Avenue, Newport Beach, California
92660.     
 
  At the Meetings, CBC and KRES stockholders will each separately consider and
vote upon the Agreement and Plan of Reorganization (the "Merger Agreement"), a
copy of which is attached to this Joint Proxy Statement/Prospectus as Annex 1
and is incorporated herein by reference, and the transactions contemplated
thereby, pursuant to which, upon receiving such stockholder approval and
subject to the satisfaction or waiver of certain conditions: (1) Acquisition
Corporation will merge into KRES (the "Merger"), with KRES surviving the
Merger; (2) holders of KRES Common will receive (A) a number of shares of CBC
Common equal to 0.776175 (the "Stock Exchange Ratio") multiplied by the number
of shares of KRES Common held by such KRES stockholder (subject to adjustment
as more fully described herein); and (B) a number of warrants to purchase CBC
Common (the "Warrants") equal to 600,000 divided by (i) the number of shares of
KRES Common outstanding immediately prior to the Effective Time plus (ii) the
number of shares of KRES subject to KRES options outstanding and held by
individuals who are directors, employees or consultants of KRES or its
subsidiaries immediately prior to the Effective Time (the "Warrant Exchange
Ratio") (the Warrant Exchange
 
                                       7
<PAGE>
 
(0.083238 Warrants per share of KRES Common based on an assumed aggregate of
7,208,243 shares of KRES Common Stock outstanding and underlying such KRES
Options immediately prior to the Effective Time) multiplied by the number of
shares of KRES Common held by such KRES stockholder; (3) the outstanding
options to acquire KRES Common held by directors, employees or consultants of
KRES or its subsidiaries immediately prior to the Effective Time (the "KRES
Options") will be exchanged for equivalent options to purchase CBC Common and
holders of such KRES Options will receive a number of Warrants to purchase CBC
Common equal to 0.083238 (based on an assumed aggregate of 7,208,243 shares of
KRES Common Stock outstanding and underlying such KRES options immediately
prior to the Effective Time) multiplied by the number of shares of KRES Common
underlying such KRES Options; (4) options to purchase an aggregate of 550,000
shares of CBC Common will be granted to five employees or directors of KRES who
will become employees or directors of CBC and (5) KRES will become a wholly-
owned subsidiary of CBC, whose stock will immediately be contributed by CBC to
its principal operating subsidiary, CB Commercial Real Estate Group, Inc. ("CBC
Group") thereby making KRES a subsidiary of CBC Group. The number of shares of
CBC Common issued in connection with the Merger will not exceed 5,614,261
(including shares of CBC Common underlying CBC Options issued in exchange for
KRES Options), and the number of shares into which the Warrants are exercisable
will not exceed 600,000. Each Warrant shall be exercisable into one share of
CBC Common at an exercise price of $30.00 per share of CBC Common. In addition,
each Warrant will be subject to the terms and conditions of a Warrant
Agreement, a copy of which is attached hereto as Annex 2 and is incorporated
herein by reference. The Stock Exchange Ratio is also to herein as the
"Exchange Ratio" and is subject to adjustment under certain circumstances as
more fully described herein. See "THE MERGER." The holders of CBC Common as of
the effective time of the Merger (the "Effective Time") will continue to hold
their securities following the Merger. See "THE MEETINGS."
 
  The Exchange Ratio was reached as a result of negotiations between management
of CBC and certain stockholders of KRES, and was later approved by the CBC
Board and the KRES Board after consultation with their advisors. See
"Background and Reasons for the Merger" for a description of the factors
considered in determining the Exchange Ratio.
 
  In addition, at the CBC Meeting, the holders of CBC Common, Series A-1
Preferred Stock ("CBC A-1 Preferred") and Series A-2 Preferred Stock ("CBC A-2
Preferred") will also be asked to consider and act upon the following matters:
 
  1. To elect nineteen (19) Directors to serve as such until the next Annual
Meeting of CBC Stockholders and until their successors are elected and
qualified;
 
  2. To approve CBC's 1997 Employee Stock Option Plan;
 
  3. To approve the CBC's 1998 Employee Stock Purchase Plan;
 
  4. To approve an amendment to CBC's 1991 Service Providers Stock Option Plan
to clarify that options may be granted either at fair market value or, when an
employee or independent contractor has given up the right to receive cash
compensation, at an appropriate discount;
 
  5. To approve CBC's 1996 Equity Incentive Plan.
 
  6. To ratify the appointment of Arthur Andersen LLP as independent
accountants for CBC for 1997; and
 
  7. To consider and act upon such other matters as may properly come before
the CBC Meeting.
 
  Holders of KRES Common will not act on these proposals. This Joint Proxy
Statement/Prospectus is being furnished to holders of CBC Common. The holders
of CBC's other classes of stock not subject to the proxy solicitation
requirements of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") are also being sent copies of this Joint Proxy Statement/Prospectus.

RECOMMENDATION OF CBC AND KRES BOARDS OF DIRECTORS
 
  Each of the Board of Directors of CBC (the "CBC Board") and the Board of
Directors of KRES (the "KRES Board") unanimously approved the Merger Agreement
and believes that the transactions contemplated thereby are fair and in the
best interests of their respective stockholders. Each Board unanimously
recommends that its stockholders vote in favor of the Merger Agreement and the
transactions contemplated thereby. See "BACKGROUND AND REASONS FOR THE MERGER."
 
RECOMMENDATION OF CBC BOARD OF DIRECTORS FOR PROPOSALS OTHER THAN THE MERGER
 
  The CBC Board has approved, by a unanimous vote of those directors present,
the 1997 Employee Stock Option Plan, the 1998 Employee Stock Purchase Plan, the
proposed amendment to the 1991 Service Providers Stock Option Plan and the 1996
Equity Incentive Plan and has appointed the firm of Arthur Andersen LLP,
Certified Public Accountants. The CBC Board also recommends a vote in favor of
each of these proposals and in favor of ratifying the appointment of Arthur
Andersen LLP.
 
OPINION OF FINANCIAL ADVISOR
 
  CBC retained Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill
Lynch") to render an opinion to the CBC Board with respect to CBC's proposed
business combination with KRES. On April 22, 1997, Merrill Lynch delivered its
opinion (the "Merrill Lynch Opinion") to the CBC Board that, as of such date
and based upon and subject to certain factors and assumptions set forth
therein, the aggregate consideration to be paid by CBC as set forth in the
April 18, 1997 draft of the Merger Agreement (the "Transaction Consideration")
is fair to CBC from a financial point of view. On June 6, 1997, Merrill Lynch
delivered a letter to CBC which informed CBC that, based upon the terms of the
final Merger Agreement dated May 14, 1997, it would not have modified its
opinion dated April 22, 1997 that the aggregate consideration to be paid by CBC
in the Merger is fair from a financial point of view to CBC. The full text of
the Merrill Lynch Opinion and the June 6, 1997 update letter, which set forth
the assumptions made, matters considered and limitations on the review
undertaken by Merrill Lynch, are attached as Annex 3 to this Joint Proxy
Statement/Prospectus. Stockholders of CBC are urged to read the Merrill Lynch
Opinion and the June 6, 1997 letter in their entirety. See "OPINION OF
FINANCIAL ADVISOR."
 
VOTE REQUIRED; SHARE OWNERSHIP
 
  The Merger. Approval of the Merger Agreement by the stockholders of CBC is
not required under Delaware law or the CBC Fourth Restated Certificate of
Incorporation (the "CBC Certificate"). However, the rules of the Nasdaq
National Market require such approval by a majority of the votes cast by the
CBC stockholders. Accordingly, the affirmative vote of a majority of the total
votes cast by the holders of CBC Common, CBC A-1 Preferred and CBC A-2
Preferred, voting together as a single class, and the holders of a majority of
the outstanding shares of KRES Common present at the KRES Meeting in person or
by proxy are required to approve the Merger Agreement.
 
  Holders of CBC A-1 Preferred are entitled to two votes per share, holders of
CBC A-2 Preferred are entitled to one vote per share, holders of CBC Common are
entitled to one vote per share and holders of KRES Common are entitled to one
vote per share. Only stockholders of record at the close of business on July 7,
1997 are entitled to notice of, and to vote at, the Meetings. See "THE
MEETINGS--The CBC Meeting."
   
  As of July 7, 1997, there were (i) 13,460,436 shares of CBC Common
outstanding, of which 18.6% was beneficially owned by directors and executive
officers of CBC and their respective affiliates and (ii) 6,680,743 shares of
KRES Common outstanding of which 97% was beneficially owned by directors and
executive officers of KRES and their respective affiliates.     
 
                                       9
<PAGE>
 
 
  Other Matters to be Considered by CBC Stockholders. Directors of CBC are
elected annually by a plurality of the votes of the shares entitled to vote at
the CBC Meeting. A vote of a majority of the outstanding votes entitled to be
cast by the holders of CBC A-1 Preferred, CBC A-2 Preferred and CBC Common,
voting together as a single class, is required to approve the CBC 1997 Employee
Stock Option Plan, the CBC 1998 Employee Stock Purchase Plan and the proposed
amendment to the CBC 1991 Service Providers Stock Option Plan and the 1996
Equity Incentive Plan and to ratify the appointment of Arthur Andersen LLP as
independent accountants.
 
EFFECTS OF THE MERGER
 
  Certain Federal Income Tax Considerations. The Merger is intended to qualify
as a "reorganization" within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended. If the Merger so qualifies, stockholders of
KRES generally would recognize no gain or loss on the exchange of their shares
of KRES Common for shares of CBC Common. However, KRES stockholders may
recognize gain with respect to the receipt of Warrants. ALL KRES STOCKHOLDERS
ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES
TO THEM OF THE MERGER. See "CERTAIN EFFECTS OF THE MERGER--Certain Federal
Income Tax Considerations."
 
  Accounting Treatment. The Merger will be accounted for by CBC under the
purchase method of accounting. See "CERTAIN EFFECTS OF THE MERGER--Accounting
Treatment."
 
OPERATIONS FOLLOWING THE MERGER
 
  Following the Merger, CBC presently intends to combine the KRES property
management and brokerage operations with the property management and brokerage
operations of CBC. The facility management operations of KRES will be combined
with the corporate services operations of CBC while the pension advisory/assets
management business of KRES generally will operate on a parallel but
independent basis. CBC currently intends (i) to continue its expansion plans of
CBC within its existing geographic market area, (ii) to utilize the "best of
class" of the current product and marketing strategies of CBC and KRES (iii) to
utilize the cross-learning opportunities and complementary services the
consolidated operations will provide, and (iv) to realize certain cost savings
and operational efficiencies as a result of the consolidation of various
business operations and corporate functions. See "OPERATIONS FOLLOWING THE
MERGER."
 
  The current CBC directors are expected to remain as directors of CBC
following the Merger. In addition, following the Merger, so long as certain
KRES shareholders who are signatories to the Merger Agreement (collectively,
the "KRES Shareholders") hold shares equal to 60% of the shares originally
issued to them pursuant to the Merger Agreement, three individuals selected by
such shareholders (and reasonably satisfactory to the Corporate Governance
Committee of the CBC Board) shall be nominated for election to the CBC Board.
For so long as they are employed or engaged by CBC two of those individuals
will be Raymond E. Wirta and Donald M. Koll, current KRES directors. In
addition to the three directors referred to above, following the Effective Time
and until the election of directors to CBC's Board at the first annual meeting
of stockholders following the Effective Time, CBC will cause one individual
selected by AP KMS II, LLC (a principal current stockholder of KRES) and
reasonably satisfactory to the Corporate Governance Committee of CBC's Board to
be nominated for election to CBC's Board. In the event that the KRES
Shareholders no longer hold shares equal to 60% of the shares originally issued
to them pursuant to the Merger Agreement, so long as FS Equity Partners III,
L.P. and FS Equity Partners International, L.P. (collectively "FS") own 60% of
the shares originally issued to FS pursuant to the Merger Agreement, CBC will
cause one individual selected by FS and reasonably satisfactory to the
Corporate Governance Committee of the CBC Board to be nominated for election to
CBC's Board. CBC expects to retain all of its current executive officers and
substantially all of its senior management (although not necessarily in their
current positions) following the Merger. Following the Merger, Raymond E. Wirta
will be appointed as President--Capital Markets of CBC and William S. Rothe
will be appointed Senior
 
                                       10
<PAGE>
 
Executive Vice President of CBC Group. A majority of the other executive
officers of KRES will become senior officers of CBC Group. See "OPERATIONS
FOLLOWING THE MERGER," "INTERESTS OF CERTAIN PERSONS IN THE MERGER," "SELECTED
INFORMATION WITH RESPECT TO KRES--Directors and Executive Officers," and
"SELECTED INFORMATION WITH RESPECT TO CBC--Directors and Executive Officers."
 
TERMS OF THE MERGER AGREEMENT
 
  Effective Time. If the Merger Agreement is approved by the requisite CBC
stockholder vote and the requisite KRES stockholder vote and if all other
conditions set forth in the Merger Agreement are satisfied or waived, the
Merger will become effective on the day an agreement of merger is filed with
the Delaware Secretary of State or such later time as specified in the
Certificate of Merger (the "Effective Time"). Assuming all other conditions to
the Merger are satisfied or waived, it is anticipated that the filing of such
agreement of merger will occur promptly after the stockholders of CBC and KRES
approve the Merger Agreement. See "THE MERGER--Effective Time."
 
  Exchange of Certificates. Prior to the Effective Time, transmittal forms will
be sent by Walter V. Stafford, Secretary of CBC, to the holders of KRES Common
to be used for forwarding their KRES stock certificates to CBC for surrender
and exchange for certificates representing CBC Common and Warrant Certificates.
See "THE MERGER--Exchange of Certificates."
 
  Conditions. The respective obligations of CBC and KRES to effect the Merger
are subject to various conditions described in "THE MERGER--Conditions to the
Merger," which include but are not limited to: (i) requisite stockholder
approvals, (ii) the absence of any restraining order or injunction that would
prevent the consummation of the Merger, (iii) the performance by the other
party of its obligations under the Merger Agreement and the accuracy of the
other party's representations and warranties contained therein, and (iv) the
receipt of an opinion from legal counsel as to certain legal and tax matters.
The respective obligations of CBC and KRES to consummate the Merger are
conditioned upon all waiting periods (and any extensions thereof) applicable to
consummation of the Merger under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended (the "HSR Act") having expired or terminated. On June
6, 1997, CBC and each of FS Equity Partners III, L.P. ("FSEP III") and Donald
M. Koll filed the information and materials required under the HSR Act with the
Antitrust Division of the United States Department of Justice and the Federal
Trade Commission with respect to the Merger. On July 6, 1997, the waiting
period terminated. CBC and KRES are not currently aware of any other material
governmental permits, approvals, consents or similar actions that are required
for consummation of the Merger, except for compliance with applicable federal
and state securities laws.
 
  Termination. The Merger Agreement is subject to termination at the option of
either CBC or KRES if the Merger is not consummated by October 31, 1997 and
prior to that time upon the occurrence of certain events. The Merger Agreement
may be terminated by CBC if over 100,000 shares of KRES Common vote against the
Merger, file a written demand for appraisal of such shares and otherwise act to
perfect their rights as dissenting stockholders under Delaware law. See "THE
MERGER--Termination" and "APPRAISAL RIGHTS."
 
  KRES Options. Pursuant to the Merger Agreement, CBC will assume the KRES
Options outstanding under the KRES Amended Nonqualified Performance Stock
Option Plan (the "KRES Performance Option Plan") held by various individuals
who are directors, employees or consultants of KRES or its subsidiaries
immediately prior to the Effective Time by substituting a CBC Option for each
such KRES Option. Each CBC Option so substituted by CBC will continue to be
subject to substantially the same terms and conditions set forth in the KRES
options plans, except that (i) such CBC Options will be exercisable for that
number of whole shares of CBC Common equal to the product of the number of
shares of KRES Common that were purchasable under such KRES Options immediately
prior to the Effective Time multiplied by the Stock Exchange Ratio, and (ii)
the per share exercise
 
                                       11
<PAGE>
 
price for the shares of CBC Common issuable upon exercise of such CBC Option
will be equal to the quotient determined by dividing the exercise price per
share of KRES Common at which such KRES Option was exercisable immediately
prior to the Effective Time by the Stock Exchange Ratio. Following the
Effective Time, each such individual entitled to receive a CBC Option will
receive a number of Warrants to purchase CBC Common equal to 0.083238 (based on
an assumed aggregate of 7,208,243 shares of KRES Common outstanding and
underlying such KRES Options immediately prior to the Effective Time)
multiplied by the number of shares of KRES Common into which such KRES Option
is exercisable. As of May 31, 1997, there were outstanding options to purchase
532,500 shares of KRES Common. See "THE MERGER--Effect on Employee Benefit and
Stock Plans."
 
  CBC Options to Certain KRES Affiliates. Raymond E. Wirta (KRES' Chief
Executive Officer, who will become President--Capital Markets of CBC and CBC
Group) and William S. Rothe (KRES' President, who will become a Senior
Executive Vice President of CBC and CBC Group) will each receive a 10-year
option for 100,000 shares of CBC Common at an exercise price of $22.75, and
Richard Abraham and Richard Wollack (senior executives of KRES who will become
senior executives of CBC and CBC Group) will each receive a 10-year option to
purchase 50,000 shares of CBC Common at an exercise price of $22.75. Each of
these options vests as to one-third of the shares three years after the
Effective Time, two-thirds after four years and all of the shares after five
years. If an optionee's employment terminates he forfeits all unvested shares.
Donald M. Koll will become a director of and a consultant to CBC and will
receive a 10-year option to purchase 250,000 shares of CBC Common at a price of
$36.75 per share. This option is fully exercisable at anytime but terminates
one year after Mr. Koll ceases to be a consultant to CBC. Mr. Koll's consulting
arrangement may be terminated by either party at any time.
 
CERTAIN OTHER AGREEMENTS
 
  Voting Agreement with Certain KRES Shareholders. On May 14, 1997 CBC, KRES
and the KRES Shareholders entered into a Voting Agreement which provides, among
other things, that (i) the KRES Shareholders agree to vote their shares of KRES
Common in favor of the Merger and (ii) FS, which holds approximately 65% of the
outstanding KRES Common in the aggregate, agreed not to vote to elect or remove
directors or change the current composition of the KRES Board. As of May 31,
1997, the seven stockholders and optionholders who are parties to such
agreement held in the aggregate approximately 96.7% of the outstanding KRES
Common (approximately 91.1% on a fully diluted basis) and options to purchase
115,000 shares of KRES Common. The remaining 31 shareholders and optionholders
of KRES who, as of May 31, 1997, held approximately 3.3% of the outstanding
KRES Common (approximately 8.9% on a fully diluted basis) and options to
purchase 342,500 shares of KRES Common are not parties to the Voting Agreement
with CBC. Only stockholders are entitled to vote, optionholders have no voting
rights. See "CERTAIN OTHER AGREEMENTS--Voting Agreements."
 
  KRES Proxy Agreements. CBC has entered into certain proxy agreements with
each of the KRES shareholders who are parties to the Voting Agreement pursuant
to which such shareholders have granted CBC irrevocable proxies to vote KRES
Common held by such shareholders in favor of the Merger Agreement. See "CERTAIN
OTHER AGREEMENTS--KRES Proxy Agreements."

COMPARISON OF STOCKHOLDERS' RIGHTS
 
  The rights of stockholders of KRES are currently governed by applicable
Delaware law, the KRES Certificate of Incorporation, the KRES Bylaws and that
certain Third Amended and Restated Stockholders Agreement dated as of January
9, 1997. Subject to the valid exercise of appraisal rights, if any, holders of
KRES Common outstanding as of the Effective Time will become stockholders of
CBC, a Delaware corporation, and their rights as CBC stockholders from and
after the Merger will be governed by applicable Delaware law, CBC's Certificate
and CBC's Bylaws. Certain differences exist between the rights of stockholders
of KRES under the KRES Certificate of Incorporation and the KRES Bylaws and the
rights of stockholders under CBC's Certificate and CBC's Bylaws. See
"COMPARISON OF THE RIGHTS OF HOLDERS OF CBC COMMON AND KRES COMMON."
 
REGISTRATION RIGHTS
 
  Pursuant to a registration rights agreement between CBC and the holders of
its Preferred Stock, CBC will use its best efforts to include in a CBC-
initiated registration shares of CBC Common into which the Preferred Stock is
convertible under certain circumstances. In addition, in connection with the
Merger, CBC entered into a registration rights agreement with certain
shareholders of KRES which provides for the registration of shares of CBC
Common issued to such shareholders in connection with the Merger or upon the
exercise of the Warrants. Pursuant to this agreement, upon the request by such
shareholders holding a threshold amount of CBC Common, CBC is obligated to use
its best efforts to initiate two registrations during its 1998 fiscal year, two
during its 1999 fiscal year and two during the period beginning fiscal year
2000 and ending and the end of fiscal year 2002. Each such registration is
required to be underwritten. CBC is obligated to keep the first such
registration effective for a period of 90 days and, in the case of each other
such registration, for a period of 60 days. See "DESCRIPTION OF CBC CAPITAL
STOCK--Registration Rights."
 
APPRAISAL RIGHTS
 
  Except to the extent such rights may have been waived, holders of KRES Common
who object to the Merger in accordance with the statutory procedures prescribed
in the Delaware General Corporation Law (the "Delaware Corporation Law") may be
entitled to receive cash for their stock if such stockholders do not vote in
favor of the Merger, validly file demands for appraisal, demonstrate to KRES'
and CBC's satisfaction (including through a court order in an appraisal
proceeding) that such shares are entitled to appraisal rights and otherwise act
to perfect their rights as dissenting stockholders pursuant to the Delaware
Corporation Law. For a description of appraisal rights under the Delaware
Corporation Law and the method of perfecting such rights, see "APPRAISAL
RIGHTS." The Merger Agreement may be terminated by CBC if more than 100,000
shares of KRES Common validly perfect their rights of appraisal of such stock
and demonstrate to KRES' satisfaction (including through a court order in an
appraisal proceeding) that such shares are entitled to appraisal rights. See
"THE MERGER--Termination."
 
RISK FACTORS
 
  Stockholders of CBC and KRES should carefully review the matters set forth
under "RISK FACTORS" before voting on the Merger.

  Neither CBC nor KRES has ever paid cash dividends on its respective common
stock. Both CBC and KRES presently intend to retain earnings for the
development of their respective businesses and do not anticipate paying cash
dividends on their common stock in the foreseeable future. CBC's Credit
Agreement with The Sumitomo Bank, Ltd., as agent for the majority lenders,
prohibits the payment of cash dividends in excess of 50% of CBC's cumulative
consolidated net income in any fiscal year. Such distributions are prohibited
under the terms of KRES' credit facility with Bankers Trust Company, as agent
for the lenders who are parties thereto.

SUMMARY HISTORICAL AND PRO FORMA COMBINED FINANCIAL AND OTHER DATA
 
  The following information sets forth summary financial and other data for
each of CBC and KRES. This information should be read in conjunction with and
is qualified in its entirety by the separate historical consolidated financial
statements and accompanying notes of CBC and KRES included herein or
incorporated herein by reference. The Pro Forma Combined Summary Financial Data
is intended for informational purposes and is not necessarily indicative of the
future financial position or future results of operations of the combined
company or of the financial position or the results of operations of the
combined company that would have actually occurred had the Merger been in
effect as of the date or for the periods presented.

         CBC SELECTED CONSOLIDATED HISTORICAL FINANCIAL AND OTHER DATA
 
  The following table sets forth selected financial and other data for CBC on a
consolidated historical basis for the periods and dates indicated. The selected
historical balance sheet data as of December 31, 1996 and 1995 and the
statement of operations data for each of the three years in the period ended
December 31, 1996 are derived from the financial statements of CBC that have
been audited by Arthur Andersen LLP, independent public accountants, and
incorporated by reference herein. The selected historical balance sheet data as
of December 31, 1994, 1993 and 1992 and the statement of operations data for
the years ended December 31, 1993 and 1992 are derived from audited financial
statements not included herein. The selected historical financial data for each
of the three-month periods ended March 31, 1997 and 1996 are derived from
unaudited financial statements prepared on the same basis as the audited
financial statements and containing, in the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the financial position at such dates and the operating
results and cash flows for such periods. Period to period comparability in 1995
and 1996 is affected by the Westmark acquisition completed in June 1995 and the
L.J. Melody acquisition completed in July 1996. A significant portion of CBC's
revenue is transactional in nature and seasonal. Historically, this seasonality
has caused CBC's revenue, operating income and net income to be lower in the
first two calendar quarters and higher in the third and fourth calendar
quarters of each year. The results of operations for the three months ended
March 31, 1997 are not necessarily indicative of results to be expected for the
entire year ending December 31, 1997 or for any future period.

(1) Amounts for 1993 and 1992 reflect the amortization of intangibles
    associated with the acquisition in 1989 of CB Commercial Real Estate Group,
    Inc. of $42.9 million and $40.7 million, respectively.
 
(2) EBITDA represents earnings before interest, income taxes, depreciation and
    amortization, thereby removing the effect of certain non-cash charges on
    income, consisting of depreciation and the amortization of intangible
    assets relating to acquisitions. Management believes that the presentation
    of EBITDA will enhance a reader's understanding of CBC's operating
    performance and ability to service debt as it provides a measure of cash
    generated that can be used by CBC to service its debt and for other
    required or discretionary purposes. Management has used EBITDA as one of
    the primary measures of operating performance in evaluating its recent
    acquisitions. Net cash available to CBC for discretionary purposes
    represents remaining cash, after debt service and other cash requirements,
    such as capital expenditures, are deducted from EBITDA. EBITDA should not
    be considered as an alternative either (i) to operating income (determined
    in accordance with generally accepted accounting principles ("GAAP")) or
    (ii) to operating cash flow (determined in accordance with GAAP). The
    measure entitled "EBITDA" may not be comparable to similarly entitled
    measures reported by other companies.
 
(3) The ratio of earnings to fixed charges represents earnings before income
    taxes and fixed charges divided by fixed charges. Fixed charges include
    interest expense and one-third of rent expense relating to operating
    leases. Deficiency of earnings to fixed charges is presented for periods
    when CBC's earnings were not sufficient to cover its fixed charges
    requirement. Earnings included non-cash depreciation and amortization
    charges of $3.1 million, $3.3 million, $13.6 million, $11.6 million, $8.1
    million, $49.6 million and $45.9 million for the three month periods ended
    March 31, 1997 and 1996, and for the years ended December 31, 1996, 1995,
    1994, 1993 and 1992, respectively.

the three month periods ended March 31, 1997 and 1996 and for the nine month
period ended December 31, 1995 are derived from unaudited financial statements.
The unaudited financial statements include all adjustments, consisting of
normal recurring accruals, which KRES considers necessary for a fair
presentation of the financial position and the results of operations for these
periods. Operating results for the three month period ended March 31, 1997 are
not necessarily indicative of the results that may be expected for the entire
year ending December 31, 1997.
 
  The financial and other data presented below are qualified by reference to
and should be read in conjunction with KRES' audited consolidated historical
financial statements and notes thereto, "Business and Financial Information
Regarding KRES--Management's Discussion and Analysis of Financial Condition and
Results of Operations of KRES," and other information included elsewhere in
this Joint Proxy Statement/Prospectus.

(1) The financial data for KRES reflect the effects of the merger of Koll
    Management Services, Inc. into KRES (the "KRES/KMS Merger") and as a result
    are not comparable to the financial data for Koll Management Services, Inc.
    (the Predecessor Company) prior to the Merger.
 
(2) A significant component of KRES' revenue is transactional in nature which
    is subject to certain seasonality. Historically, KRES' revenue, operating
    income and net income in the first and fourth quarters of its fiscal years
    are generally lower than in the second and third quarters due to these
    fluctuations, which is consistent with industry trends. Therefore,
    quarterly results are not necessarily representative of results for the
    entire year.
 
(3) See Note 1 of Notes to KRES Consolidated Financial Statements.
 
(4) EBITDA represents earnings before interest, income taxes, depreciation and
    amortization, thereby removing the effect of certain non-cash charges on
    income, consisting of depreciation and the amortization of intangible
    assets relating to acquisitions. Non-cash compensation expense under stock
    award plans of $329,000 for the period ending December 31, 1996, certain
    other non-recurring items including compensation expense related to the
    KRES/KMS merger of $1,208,000 for the eight months ending November 30, 1994
    and recognition of certain costs related to KRES' IPO effort and the
    unexpected loan fees related to the previous credit facility repaid in
    January 1997 of $1,390,000 for the period ending March 31, 1997 are
    included as expenses which have the effect of reducing EBITDA.
 
   Management believes that the presentation of EBITDA will enhance a reader's
   understanding of KRES' operating performance and ability to service debt as
   it provides a measure of cash generated that can be used by KRES to service
   its debt and for other required or discretionary purposes. Management has
   used EBITDA as one of the primary measures of operating performance in
   evaluating its recent acquisitions. EBITDA should not be considered as an
   alternative either (i) to operating income (determined in accordance with
   generally accepted accounting principles ("GAAP")), or (ii) operating cash
   flow (determined in accordance with GAAP). The measure entitled "EBITDA" may
   not be comparable to similarly entitled measures reported by other
   companies.

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
                                  (UNAUDITED)
 
  The following unaudited pro forma balance sheet as of March 31, 1997 and
statements of operations for the three months ended March 31, 1997 and for the
year ended December 31, 1996 ("the pro forma financial statements") give effect
to (i) the Merger as if it had occurred as of January 1, 1996 in the pro forma
combined statements of operations and as of March 31, 1997 in the pro forma
combined balance sheet and (ii) the acquisition, in the pro forma combined
statements of operations for the year ended December 31, 1996, of L. J. Melody
by CBC as if this acquisition had occurred as of January 1, 1996. See
"DESCRIPTION OF CAPITAL STOCK and THE MERGER."
 
  The pro forma adjustments are based upon currently available information and
upon certain assumptions that management believes are reasonable. The Merger
and the acquisition of L. J. Melody have been accounted for by CBC as a
purchase. The adjustments included in the pro forma financial statements
represent the effects of CBC's preliminary determination and allocation of the
purchase price to the fair value of the assets and liabilities acquired, based
upon currently available information. There can be no assurance that the actual
effects will not differ significantly from the pro forma adjustments reflect in
the pro forma financial statements.
 
  The pro forma financial statements are not necessarily indicative of either
future results of operations or results that might have been achieved if the
transactions had been consummated as of the dates indicated. The pro forma
financial statements should be read in conjunction with the historical
consolidated financial statements and footnotes of CBC, KRES and L. J. Melody
included herein.

(a) Represents the write-off of amounts related to certain KRES deferred costs
    that have been reallocated to the purchase price of assets acquired by CBC.
    These costs consisted primarily of costs to organize and structure
    investment funds in which KRES holds general partnership interests ($6.1
    million), investments and advances ($1.7 million), organization costs ($1.2
    million) and miscellaneous other assets.
 
(b) Represents the fair value of CBC Common Stock, options and warrants
    expected to be issued in connection with the Merger and the elimination of
    KRES equity. The purchase price included the following amounts attributable
    to the CBC Common Stock, options and warrants:

(d) Represents an adjustment to accrue the following as a component of purchase
    price:
 
<TABLE>
      <S>                                                            <C>
      Severance for KRES employees expected to be terminated........ $2,011,000

      Integration costs.............................................    492,000
      Transaction fees and related costs............................  3,975,000
</TABLE>
 
  Integration costs consist primarily of third party costs for certain
  software modifications required to be made to the KRES computer systems in
  order to make them compatible with operational requirements of the combined
  entity. Transaction fees and related costs consist primarily of investment
  banker fees, the cost of financial due diligence, legal and accounting
  fees.
 
(e) Represents the component of the purchase price allocated to the estimated
    current fair value of incentive fees KRES is entitled to receive upon the
    liquidation of real estate investment funds KRES manages.
 
(f) Represents the adjustment to reflect KRES' management contracts at their
    estimated current fair value.
 
(g) Represents the adjustment to reflect KRES' investments at their estimated
    current fair value.
 
(h) Represents adjustments to reflect the tax effect of the pro forma
    adjustments including adjustments to goodwill for deferred taxes resulting
    from KRES related items and adjustments to retained earnings for deferred
    taxes resulting from CBC related items.
 
(i) CBC expects to incur additional costs resulting from the merger associated
    with severance for CBC employees expected to be terminated and CBC's system
    integration costs. The pro forma combined balance sheet does not reflect an
    adjustment related to such costs which are currently estimated at $6.5
    million.

         NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS
                   FOR THE THREE MONTHS ENDED MARCH 31, 1997
 
(a) Represents the gross up of commissions paid by KRES to its brokers as
    revenues and commission expense to conform to CBC's reporting format.
 
(b) Represents an adjustment to reflect KRES's revenues and operating costs net
    of onsite reimbursable costs incurred and charged to tenants, in order to
    conform to CB's reporting format.
 
(c) Represents reversal of KRES's historical amortization expense related to
    its goodwill, amortization of certain deferred costs and other intangibles.
 
(d) Represents amortization expense for management agreements assuming a useful
    life of 10 years for facilities management and 4 years for property
    management contracts. Property management contracts generally have 30-day
    renewable terms and facilities contracts have an average remaining term of
    7 years, including automatic renewal options. Most contracts also have
    additional renewal option periods.
 
   The 4 year life for property management contracts is based on KRES's
   historical experience of 25 percent average annual runoff rate on such
   contracts. An amortization period of 10 years was selected for facilities
   contracts as KRES has a history of runoff on such contracts of approximately
   10 percent per annum. The facilities management contracts are based on long
   standing relationships with clients and have historically proven to maintain
   a relatively consistent runoff rate and most of them have been consistently
   renewed at their respective renewal dates. CBC expects to continue to have a
   similar experience with these contracts.
 
(e) Represents amortization expense on KRES's investments to amortize the
    difference between the purchase price allocated to these investments and
    their underlying net book value.
 
(f) Represents amortization expense for total goodwill resulting from the
    transaction using a 30 year estimated useful life.
 
(g) Represents reversal of KRES's tax benefit associated with its historical
    amortization expense.
 
(h) Represents the tax effect of the pro forma adjustments.
 
(i) Represents amortization expense for covenants not to compete over the
    average remaining terms of 3 years.
 
(j) Reflects the effect of the pro forma number of weighted average common
    stock and common stock equivalent shares giving effect to the CBC Common
    and CBC Common equivalent shares to be issued in connection with the
    Merger. The weighted average number of shares are calculated as follows:

         NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS
 
                      FOR THE YEAR ENDED DECEMBER 31, 1996
 
(a) Reflects the reversal of an accrual for a one-time acquisition related
    bonus to L.J. Melody employees prior to the acquisition of L.J. Melody by
    CBC.
 
(b) Reflects additional amortization compensation expense attributable to
    Lawrence J. Melody's employment.
 
(c) Reflects the amortization of net $9.0 million in intangible assets and
    goodwill assuming a useful life of 30 years.
 
(d) Reflects interest on acquisition financing.
 
(e) Reflects deferred tax benefit of certain pro forma adjustments relating to
    L.J. Melody purchase accounting entries, consisting of additional
    compensation expense, interest expense and amortization of intangibles.
 
(f) Represents the gross up commissions paid by KRES to its brokers as revenues
    and commission expense to conform to CBC's reporting format.
 
(g) Represents an adjustment to reflect KRES's revenues and operating costs net
    of onsite reimbursable costs incurred and charged to tenants, in order to
    conform to CBC's reporting format.
 
(h) Represents reversal of KRES's historical amortization expense related to
    its goodwill, amortization of certain deferred costs and other intangibles.
 
(i) Represents amortization expense for management agreements assuming a useful
    life of 10 years for facilities management and 4 years for property
    management contracts. Property management contracts generally have 30-day
    renewable terms and facilities contracts have an average remaining term of
    7 years, including automatic renewal options. Most contracts also have
    additional renewal option periods.
 
  The 4 year life for property management contracts is based on KRES's
  historical experience of 25 percent average annual runoff rate on such
  contracts. An amortization period of 10 years was selected for facilities
  contracts as KRES has a history of runoff on such contracts of
  approximately 10 percent per annum. The facilities management contracts are
  based on long standing relationships with clients and have historically
  proven to maintain a relatively consistent runoff rate and most of them
  have been consistently renewed at their respective renewal dates. CBC
  expects to continue to have a similar experience with these contracts.
 
(j) Represents amortization expense on KRES's investments to amortize the
    difference between the purchase price allocated to these investments and
    their underlying net book value.
 
(k) Represents amortization expense for total goodwill resulting from the
    transaction using a 30 year estimated useful life.
 
(l) Represents amortization expense for covenants not to compete over the
    average remaining terms of 3 years.
 
(m) Represents the tax effect of the pro forma adjustments.
 
(n) Represents reversal of KRES's tax benefit associated with its historical
    amortization expense.
 
(o) Reflects the effect of the pro forma number of weighted average common
    stock and common stock equivalent shares giving effect to the CBC Common
    and the CBC Common equivalent shares to be issued in connection with the
    Merger.

                                 RISK FACTORS
 
  In addition to the other information regarding CBC, KRES and the Merger
contained in this Joint Proxy Statement/Prospectus, the following factors
should be considered carefully by the holders of CBC A-1 Preferred, CBC A-2
Preferred, CBC Common and KRES Common before voting on the Merger. These
factors should be considered in conjunction with the information included in
this Joint Proxy Statement/Prospectus.
 
EFFECTS AND CONDITIONS OF THE MERGER
 
  Uncertainty of Anticipated Benefits
   
  Although the CBC Board and the KRES Board believe that the Merger is fair
and in the best interests of their respective stockholders, there can be no
assurance that the combined companies will realize the anticipated benefits of
the Merger. The Merger is subject to certain significant conditions, including
stockholder approval and no material adverse change in operations. In
addition, negotiation and consummation of the Merger will result in costs to
the combined companies that are estimated to be approximately $18 million as
well as additional restructuring and related charges associated with combining
the operations of the two companies. CBC intends to expense a portion of these
costs that relate to restructuring-type costs associated with CBC's operations
which are not accounted for as part of the purchase price in the quarter in
which the Merger is consummated, which is anticipated to be the third quarter
of 1997. Because of the inherent uncertainties associated with merging two
large companies, there can be no assurance that the combined companies will be
able to realize the full cost savings CBC currently expects to realize as a
result of the Merger (estimated to be $10-$12 million per year) and the
consolidation of the operations of CBC and KRES, or that such savings will be
realized at the times currently anticipated. Furthermore, there can be no
assurance that any costs savings which are realized will not be offset by
increases in other expenses or operating losses, including losses due to
problems in integrating the two companies. See "--ACQUISITIONS," "OPERATIONS
FOLLOWING THE MERGER" and "THE MERGER--General; Merger Consideration."     
 
  Difficulty of Integration
 
  CBC has never made an acquisition the size of the KRES Merger. KRES has
approximately 2,600 employees and 10 regional and 255 field offices. It has
approximately 750 property management agreements. Following the Effective
Time, CBC intends to complete the following integration steps: (1) merge all
property management functions of CBC and KRES into a single unit, (2) merge
all KRES facilities management functions into CBC's corporate services
function, (3) merge all KRES personnel, corporate accounting, legal, corporate
and administration functions into their CBC counterparts, (4) merge all KRES
brokerage operations into CBC's brokerage operations and (5) merge all KRES
mortgage banking operations into L.J. Melody. There can be no assurance that
CBC will be successful in integrating these operations, that it will realize
potential cost savings from such integration or that after the Effective Time
either CBC or KRES customers will agree to continue their relationships with
CBC. The integration (and resulting reduction in workforce) of the KRES and
CBC property management, brokerage and facility management operations as well
as the integration of the KRES and CBC accounting, personnel, administrative
and legal functions will involve a significant risk that key employees in
those operations and functions will leave even when offered continuing
employment. Certain employees could not be easily replaced and their departure
could seriously undermine the integration process thereby causing a loss of
customers. Even if all key employees remain there is a risk that customers of
either KRES or CBC may elect to terminate their agreements or that the
integration process will create a temporary inability to provide adequate
service to customers' property, facilities or asset management causing them to
terminate their relationship with KRES or CBC. The integration approach
adopted by CBC with respect to KRES requires the devotion of a significant
amount of time by senior executives, which may detract from business
operations and development of the combined companies. See "OPERATIONS
FOLLOWING THE MERGER."
 
  Reliance Upon Management by Financial Advisor
 
  Merrill Lynch, CBC's financial advisor in connection with the Merger, relied
upon the respective estimates by CBC and KRES of the financial forecast
information, synergies and related cost savings and expenses
 
                                      29
<PAGE>
 
   
expected to result from the Merger, and assumed that such synergies will be
achieved in rendering the Merrill Lynch Opinion. Without such synergies, the
assumptions set forth in the Merrill Opinion will not be achieved and Merrill
Lynch may have reached a different conclusion than that set forth in the
Merrill Lynch Opinion. Merrill Lynch assumed that the financial forecast
information, synergies and related cost savings and expenses expected to
result from the Merger furnished to or discussed with Merrill Lynch were
reasonably prepared and reflected the best currently available estimates and
judgment of the management of CBC and KRES, respectively, as to the expected
future financial performance of KRES and CBC. In analyzing certain pro forma
effects resulting from the Merger for the combined companies, including the
potential impact of the Merger on projected earnings per share ("EPS") and
earnings before taxes, depreciation and amortization ("EBITDA"), Merrill Lynch
concluded that with synergies the Merger would be accretive on an EPS and
EBITDA basis to the holders of CBC Common immediately and for the three
calendar years ended December 31, 2000. Without taking into account expected
synergies, the Merger would be dilutive to the holders of CBC Common for the
same periods. See "OPINION OF FINANCIAL ADVISOR."     
 
ADVERSE CHANGES IN ECONOMIC CONDITIONS
 
  Periods of economic slowdown or recession, rising interest rates or
declining demand for real estate will adversely affect certain segments of
CBC's business. Such economic conditions could result in a general decline in
rents which in turn would adversely affect revenues from property management
fees and brokerage commissions derived from property sales and leases. Such
conditions could also lead to a decline in sale prices as well as a decline in
demand for funds invested in commercial real estate and related assets. An
economic downturn or increase in interest rates also may reduce the amount of
loan originations and related servicing by CBC's commercial mortgage banking
business. If CBC's brokerage and mortgage banking businesses are adversely
affected, it is quite likely that other segments of CBC's business will also
be adversely affected, due to the relationship among CBC's various business
segments.
 
  The sharp downturn in the commercial real estate market beginning in the
late 1980's has caused and may continue to cause some property owners to
dispose of or lose their properties through foreclosures and has caused
certain real estate firms to undergo restructuring or changes in control. Such
changes in the ownership of properties may be accompanied by a change in
property and investment management firms and could cause the combined company
to lose management agreements or make the agreements it retains less
profitable. Revenue from property management services is generally a
percentage of aggregate rent collections from properties, with many management
agreements providing for a specified minimum management fee. Accordingly, the
success of the combined company will be dependent in part upon the performance
of the properties it manages. Such performance in turn will depend in part
upon the combined company's ability to attract and retain creditworthy
tenants, the magnitude of defaults by tenants under their respective leases,
its ability to control operating expenses, governmental regulations, local
rent control or stabilization ordinances which are or may be put into effect,
various uninsurable risks, financial conditions prevailing generally and in
the areas in which such properties are located, the nature and extent of
competitive properties and the real estate market generally.
 
GEOGRAPHIC CONCENTRATION
 
  For the year ended December 31, 1996, approximately $177.3 million or 38.5%
of CBC's total sale and lease revenue of $461.1 million and approximately $3.5
million or 14% of KRES' total sale and lease revenue of $25.0 million, was
generated from transactions originated in the state of California. As a result
of the geographic concentration in California, any negative performance of the
commercial real estate markets and the local economies in various areas within
California could materially adversely affect the combined company's results of
operations.
 
RIGHTS OF HOLDERS OF KRES COMMON FOLLOWING THE MERGER
 
  Following the Merger, holders of KRES Common outstanding as of the Effective
Time will become holders of CBC Common. Certain differences exist between the
rights of stockholders of KRES under the KRES
 
                                      30
<PAGE>
 
Certificate and the KRES By-laws and the rights of stockholders of CBC under
the CBC Certificate and the CBC By-laws. In particular, the CBC Certificate
provides for voting rights, dividend rights and liquidation preferences for the
holders of the CBC Preferred which are superior to those of the holders of CBC
Common. Holders of KRES Common are not subject to any such superior rights. In
addition, the rights of certain holders of KRES Common are governed by a
Stockholders Agreement and other agreements to which such holders are parties.
As a condition to the Merger, the Stockholders Agreement and similar agreements
relating to equity securities of KRES will be terminated. See "PROPOSAL FOR
NOMINATION AND ELECTION OF CBC DIRECTORS--Stockholders Agreement and
Registration Rights Agreements" and "COMPARISON OF THE RIGHTS OF STOCKHOLDERS
OF CBC AND KRES."
 
UNCERTAIN FEDERAL INCOME TAX TREATMENT OF THE WARRANTS TO BE RECEIVED BY
HOLDERS OF KRES COMMON
 
  The Merger is intended to constitute a tax-free reorganization within the
meaning of the Internal Revenue Code of 1986, as amended (the "Code"). Existing
Treasury Regulations promulgated under the Code treat the Warrants to be
received in connection with the Merger as neither stock nor securities for
reorganization purposes. However, under applicable case law preceding such
regulations, the Warrants could be treated as securities for reorganization
purposes. In December 1996, the Department of the Treasury proposed regulations
which would treat the Warrants as securities without a principal amount. As
presently drafted, such regulations would apply to exchanges occurring on or
after 60 days following its adoption. Such regulations, however, have not yet
been adopted. Thus, at the present time, it is not clear whether the Warrants
received by the KRES stockholders will be treated for purposes of the Merger as
"stock or securities" or as property other than "stock or securities". In
connection with the Merger, counsel for KRES and certain holders of KRES Common
has issued an opinion that (a) no gain or loss will be recognized by the
holders of KRES Common who exchange all their KRES Common for CBC Common and/or
Warrants in the Merger, (b) the aggregate basis of the CBC Common received by
each holder of KRES Common will be the same as the aggregate basis of such
holder in KRES Common exchanged therefor in the Merger, (c) the aggregate basis
of the Warrants received by each holder of KRES Common will equal zero and (d)
the holding period of the CBC Common and Warrants received by a holder of KRES
Common will include the period during which such holder held KRES Common
exchanged therefor in the Merger, provided such stock was held as a capital
asset on the Effective Date. This opinion is based upon several qualifications
and conditions, including the condition that the Warrants are treated for
purposes of the Merger as "stock or securities". The opinion by counsel for
KRES and certain holders of KRES Common further states that if the Warrants are
treated for purposes of the Merger as property other than "stock or securities"
as set forth in the existing Treasury Regulations, then (a) holders of KRES
Common will recognize gain upon receipt of the Warrants in the Merger exchange
in an amount equal to the lesser of (i) the excess of the fair market value of
the CBC Common and Warrants received over the basis of such stockholder in the
KRES Common exchanged in the Merger or (ii) the fair market value of such
Warrants received in the Merger, (b) the aggregate basis of the Warrants will
equal the fair market value of such Warrants, (c) the aggregate basis of the
CBC Common received by each holder of KRES Common surrendered in exchange
therefor decreased by the fair market value of any Warrants received and
increased by the amount of gain such holder recognizes upon receipt of the
Warrants received and increased by the amount of gain such holder recognizes
upon receipt of the Warrants and (d) the holding period for the Warrants
received in exchange for the KRES Common will commence on the day following
receipt of such Warrants. The complete text of the opinion, including the
assumptions and conditions included therein, is set forth as an exhibit to the
Registration Statement of which this Prospectus is a part.
 
POTENTIAL CONTROL BY KRES SHAREHOLDERS; BOARD REPRESENTATION
 
  Following the Merger, so long as the KRES shareholders who are signatories to
the Merger Agreement hold shares equal to 60% of the shares originally issued
to them pursuant to such agreement, CBC has agreed to cause three individuals
selected by such shareholders to be nominated to the CBC Board. In addition,
following the Effective Time and until the first meeting of CBC shareholders
thereafter, CBC has agreed to cause an individual designated by one of such
KRES shareholders to be nominated to the CBC board (in addition to the three
individuals referred to above). These individuals may have focused views
regarding shareholder values for large
 
                                       31
<PAGE>
 
shareholders which could lead to differences of opinion with other CBC
directors. Following the Merger, the KRES shareholders who are parties to the
Merger Agreement will own approximately 26.7% of the outstanding CBC Common
(excluding shares issuable upon exercise of the Warrants). As a result of the
foregoing, such KRES shareholders will exercise significant influence over
matters requiring CBC Board or stockholder approval, including the approval of
significant corporate actions. Such concentration of stock ownership may also
have the effect of delaying, deferring or preventing a change of control of
CBC. See "INTERESTS OF CERTAIN PERSONS IN THE MERGER--Proposed CBC Directors."
 
COMPETITION
 
  CBC competes in a variety of service disciplines within the commercial real
estate industry, including (i) brokerage (facilitating sales and leases on
behalf of investors), investment properties (acquisitions and sales),
corporate services, property management, and real estate market research and
(ii) mortgage banking (loan origination and servicing), investment management
and advisory services, and valuation and appraisal services. Each of these
business areas is highly competitive on a national as well as local level. CBC
faces competition not only from other real estate service providers, but also
from institutional lenders, insurance companies and investment advisory,
mortgage banking, accounting and appraisal firms. After the Merger, CBC will
continue to compete with providers of all of these services, some of which in
certain of these business areas are better established and have substantially
more experience than CBC. Moreover, although many of CBC's competitors are
local or regional firms that are substantially smaller than CBC on an overall
basis, they may be substantially larger on a local or regional basis. Because
of these factors, these companies may be better able than CBC to obtain new
customers, pursue new business opportunities or to survive periods of industry
consolidation. In addition, CBC has faced increased competition in recent
years in the property management and investment advisory segment of its
business which has resulted in decreased property management fee rates and
margins and decreased investment advisory fees and margins. Although CBC and
KRES believe that the combined operations of CBC and KRES will enable CBC to
better meet the needs of these customers, as a result of these factors, CBC
will continue to face intense competition in its existing markets and in
markets where KRES has operated. In general, in each of CBC's businesses there
can be no assurance that CBC will be able to continue to compete effectively
or that it will be able to maintain current commission or fee levels or
margins or that it will not encounter increased competition which could limit
CBC's ability to maintain or increase its market share.
 
  Coldwell Banker, a former sister company of CB Commercial Real Estate Group,
Inc., recently acquired by HFS, Inc., has announced that it intends to expand
its franchise program from the residential real estate brokerage franchising
business into commercial brokerage franchising. The activities of Coldwell
Banker franchisees as direct competitors of CBC could cause name confusion in
the industry between CBC and Coldwell Banker franchisees, which could result
in a dilution of the value of the trade name.
 
RISKS RELATED TO GENERAL PARTNER STATUS OF KRES
 
  KRES is a general partner in 39 general and limited partnerships. Eleven of
such partnerships are involved in the acquisition, rehabilitation, subdivision
and sale of multi-tenant industrial business parks, eight of such partnerships
own shopping centers and eighteen of such partnerships hold portfolios of
office, industrial and other retail real estate. As a general partner, KRES
may be liable to its partners as well as liable for the obligations of such
partnerships, including environmental liabilities. All of KRES' general
partnership interests are held through subsidiaries which may limit its
exposure to contingent liabilities to the total invested capital in and
advances to subsidiaries holding the general partnership interests.
 
RISKS INHERENT IN ACQUISITION GROWTH STRATEGY
 
 Lack of Availability of Acquisition Candidates
 
  A significant component of CBC's growth in 1995 and 1996 was, and part of
its principal strategy for continued growth is, through acquisitions. Recent
acquisitions have included L.J. Melody (mortgage banking services), Westmark
(investment management and advisory services) and Langdon Rieder Corporation
(tenant
 
                                      32
<PAGE>
 
advisory services). CBC expects to continue its acquisition program both by
consummating the merger described herein and by pursuing additional
acquisition opportunities. CBC's future growth through acquisitions will be
partially dependent upon the continued availability of suitable acquisition
candidates at favorable prices and upon favorable terms and conditions;
however, there can be no assurance that future acquisitions can be consummated
at favorable prices or upon favorable terms and conditions. In addition,
acquisitions entail risks that businesses acquired will not perform in
accordance with expectations and that business judgments with respect to the
value, strengths and weaknesses of businesses acquired or the consequences of
any such acquisition will prove incorrect.
 
  CBC's acquisition strategy is in part a response to the consolidation within
the industry which has accelerated because of increased competition. CBC is
engaged in an ongoing evaluation of potential acquisitions. No assurance can
be given as to CBC's ability to successfully complete these or future
acquisitions, or as to the financial effect on CBC of any acquired business.
Future acquisitions by CBC may result in increased interest and amortization
expense or decreased operating income, which could have a negative impact on
CBC's financial results. In addition, acquisitions, including the proposed
Merger, involve numerous risks, including difficulties in assimilating the
operations and products of the acquired companies, diversion of management's
attention from other business concerns and the uncertainty of entering markets
in which CBC has no or limited prior experience.
 
 Difficulty of Integration In Connection with Acquisition Growth Strategy
 
  There can be no assurance that significant difficulties in integrating
operations acquired from other companies will not be encountered, including
difficulties arising from the diversion of management's attention from other
business concerns and the potential loss of key employees of either CBC or the
acquired operations. CBC encountered a number of these difficulties when it
acquired Westmark and, to a lesser extent, when it acquired L.J. Melody. In
April of 1997 approximately 25 sales persons associated with the KRES
brokerage operation in Phoenix, Arizona terminated their employment with KRES
and joined Insignia, a competitor of KRES and CBC. While this particular
defection is not material to either KRES or CBC there could be a material
adverse effect if similar defections occurred in other locations. CBC believes
that most acquisitions will have an adverse impact on operating income and net
income during the first six months following the acquisition. There can be no
assurance that CBC's management will be able to effectively manage the
acquired businesses or that such acquisitions will benefit CBC overall.
 
 Lack of Available Financing
 
  CBC will require additional financing to sustain its acquisition program.
CBC expects to finance future acquisitions and internal growth through a
combination of funds available under its senior secured credit facilities,
cash flow from operations, additional indebtedness incurred by CBC (including,
in the case of acquisitions, seller financing) and public or private sales of
CBC's capital stock. The covenants in CBC's credit agreements will restrict
CBC's ability to raise additional capital in certain respects. There can be no
assurance that financing will be available to CBC or, if available, that it
will be sufficient to finance acquisitions and internal growth.
 
SEASONALITY
 
  A substantial component of CBC's revenues is transactional in nature and as
a result is subject to seasonality. Historically, CBC's revenues, operating
income and net income in the first two calendar quarters have been generally
lower than in the third and fourth calendar quarters due to seasonal
fluctuations, which is consistent with the industry generally. In the first
quarters of any calendar year, CBC has historically sustained a loss. CBC's
non-variable operating expenses, which are treated as expenses when incurred
during the year, are relatively constant in total dollars on a quarterly
basis. As a consequence of the seasonality of revenues and the relatively
constant level of quarterly expenses, a substantial majority of CBC's
operating income and net income has historically been realized in the third
and fourth calendar quarters. CBC believes that future operating results will
continue to follow these historical patterns, although revenues are also
likely to be affected by both broad economic fluctuations and supply and
demand cyclicality relating to commercial real estate. There can be no
assurance that CBC will be profitable on a quarterly or annual basis in the
future.
 
                                      33
<PAGE>
 
CBC'S LEVERAGE AND INTANGIBLE NATURE OF ITS ASSETS
 
  CBC will have indebtedness following the Merger of approximately $225
million as to which it will have principal and interest obligations of
approximately $74 million which must be paid or refinanced within the twelve-
month period following the Effective Time regardless of CBC's operating cash
flow. CBC's Credit Agreement with Sumitomo Bank Ltd. has been amended to
increase to $50 million the funds available for acquisitions. Approximately
$45 million of this amount is expected to be borrowed to repay KRES' bank
debt. Any amounts borrowed on the new $50 million acquisition line must be
repaid within six months. Any material downturn in CBC's revenue or increase
in its costs and expenses could result in CBC's being unable to meet its debt
obligations. Following the Merger CBC will have total assets of approximately
$474 million on a pro forma basis, approximately $225 million of which will be
goodwill and other intangible assets which may not be realizable at their
carrying amounts in liquidation.
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  The market price of CBC Common could be subject to significant fluctuations
in response to quarter-to-quarter variations in operating results of CBC or
its competitors, conditions in the commercial real estate industry, the
commencement of, developments in or outcome of litigation, changes in
estimates of CBC's performance by securities analysts, and other events or
factors. In addition, the stock market in recent years has experienced extreme
price and volume fluctuations that have often been unrelated or
disproportionate to the operating performance of companies. These
fluctuations, as well as general economic and market conditions, may adversely
affect the market price of the CBC Common.
 
RETAINED RISKS OF MORTGAGE LOANS SOLD
 
  In connection with CBC's origination and sale of certain mortgage loans in
its mortgage banking business, CBC must make certain representations and
warranties concerning mortgages originated by CBC and sold to "conduit"
purchasers or to the Federal Home Loan Mortgage Corporation ("Freddie Mac").
These representations and warranties cover such matters as title to the
mortgaged property, lien priority, environmental reviews and certain other
matters. CBC's representations and warranties rely in part on similar
representations and warranties made by the borrower or others. CBC would have
a claim against the borrower or another party in the event of a breach of any
of these representations or warranties; however, CBC's ability to recover on
any such claim would be dependent upon the financial condition of the party
against which such claim is asserted. There can be no assurance that CBC will
not experience a material loss as a result of representations and warranties
it makes.
 
POTENTIAL LACK OF SPACE TO LEASE
 
  A significant portion of CBC's brokerage business involves facilitating the
lease of commercial property including retail, industrial, and office space.
Since the real estate depression of the early 1990s, the development of new
retail, industrial, and office space has been limited. As a consequence, in
certain areas of the country there is beginning to be inadequate office,
industrial and retail space to meet demand and there is a potential for a
decline in CBC's overall number of lease transactions, the effect of which
may, over time, be partially offset by increasing sales, including sales of
undeveloped land (which would benefit CBC's brokerage business). During the
first five months of 1997, CBC's lease transactions have declined although
aggregate revenue has increased because of higher rents. There can be no
assurance that any such increase in the sale of undeveloped land will coincide
with any decline in the number of lease transactions.
 
ENVIRONMENTAL CONCERNS
 
  Numerous laws and regulations have been enacted which regulate exposure to
potentially hazardous materials often found in and around buildings. Some of
these laws and regulations directly and indirectly impact the commercial real
estate market by imposing additional costs and liability on owners, operators
and sellers as well as lenders. Such laws and regulations tend to discourage
sales and leasing activities and mortgage lending with respect to some
properties, and may therefore adversely affect CBC. In addition, the failure
of CBC to disclose environmental issues may subject CBC to liability to a
buyer or lessee of property or to a purchaser of a mortgage loan.

                CB COMMERCIAL REAL ESTATE SERVICES GROUP, INC.
 
  CBC's business was founded under the name Tucker, Lynch & Coldwell by
Colbert Coldwell in San Francisco in 1906 as a commercial real estate
brokerage firm. The firm was renamed Coldwell, Cornwall & Banker with the
arrival of Benjamin Arthur Banker in 1913, became Coldwell, Banker & Company
in 1940 and was acquired by Sears, Roebuck & Co. ("Sears") in 1981.
 
  In March 1989 CBC was incorporated in Delaware for the purpose of acquiring
Coldwell Banker Commercial Group, Inc. from Sears by a group of six officers
of Coldwell Banker Commercial Group, Inc. led by Mr. James J. Didion, CBC's
Chairman and Chief Executive Officer, and an investor group formed by
Mr. Frederic V. Malek and The Carlyle Group, L.P., a Washington, D.C.-based
private merchant bank. The acquisition was completed in April 1989 and the
name of Coldwell Banker Commercial Group, Inc. was changed to CB Commercial
Real Estate Group, Inc. in 1991. CBC is a holding company that conducts its
operations solely through CB Commercial Real Estate Group, Inc. and its
subsidiaries.
 
  CBC believes that it is the largest vertically-integrated commercial real
estate services company in the United States with aggregate 1996 revenue of
$583.1 million and 231 business unit offices in 107 locations. CBC provides a
full range of services to commercial real estate tenants, owners, and
investors including: (i) brokerage (facilitating sales and leases), investment
properties (acquisitions and sales on behalf of investors), corporate
services, property management, and real estate market research (collectively,
"Property and User Services"), and (ii) mortgage banking (mortgage loan
origination and servicing), investment management and advisory services, and
valuation and appraisal services (collectively, "Investor Services"). CBC
believes that, on the basis of revenues, its brokerage and independent
commercial mortgage origination businesses are the largest such businesses in
the United States, and that CBC is among the top ten providers of commercial
property management, investment management and advisory services and
commercial mortgage loan servicing in the United States. CBC's diverse client
base includes local, national and multinational corporations, financial
institutions, pension funds and other tax exempt entities, local, state and
national governmental entities, and individuals. In addition, CBC has
established exclusive alliances with international commercial real estate
service firms (DTZ in Europe, C.Y. Leung in Hong Kong, China and Singapore,
and Ikoma Corporation in Japan) which have offices in an additional 134
locations in 31 countries. These relationships are reciprocal referral
arrangements whereby CBC's clients who require services in a geographic region
serviced by its alliance partners must be referred by CBC to its alliance
partner operating in that region. Conversely, CBC's alliance partners are
obligated to refer their clients with commercial real estate needs in the
United States to CBC. These alliances have not generated significant revenues
to date.
 
PROPERTY AND USER SERVICES
 
  Property and User Services include a broad range of services, delivered
primarily to users and owners of commercial real estate, including brokerage
(facilitating sales and leases), investment properties (acquisitions and sales
on behalf of investors), corporate services, property management, and real
estate market research. These services are provided with respect to a wide
range of commercial real estate properties, including, but not limited to,
office space, industrial buildings, retail properties, multifamily residential
properties and unimproved land.
 
  Brokerage. Brokerage, CBC's original and core business, advises buyers,
sellers, landlords and tenants in connection with the leasing and sale of
office space, industrial buildings, retail properties, multifamily residential
properties and unimproved land. Brokerage employs approximately 1,600 sales
professionals nationally, generating significant deal flow and real-time
market data. This market presence provides CBC with a competitive advantage in
developing business opportunities and client contacts and in developing CBC's
brand identity for CBC's other business disciplines. CBC believes its
commercial brokerage business is the market-leader in the United States based
upon both 1996 revenue, which totaled approximately $335.4 million, and the
number of completed transactions, which totaled approximately 19,950 in 1996.
 
 
                                      35
<PAGE>
 
  Investment Properties. CBC provides sophisticated strategic planning for,
and execution of, acquisitions and sales of income-producing commercial
properties for its clients through its investment properties sales
professionals. In 1996, approximately 1,200 sales transactions were completed
with some of the country's largest and most sophisticated investors,
including, as examples, Prudential Insurance Co., RREEF and Security Capital.
With aggregate estimated sales consideration of more than $7.0 billion in
1996, CBC believes that it is one of the largest providers of investment
properties sales services in the United States.
 
  Corporate Services. Corporate services, which generally operates through the
CBC/Madison Advisory Group, addresses the multiple-market domestic and
international real estate needs of corporate America by providing
comprehensive, quality services on a cost efficient basis through a single
point-of-contact at CBC. Corporate services coordinates the utilization of all
CBC's various disciplines to deliver an integrated service to some of the
largest and most sophisticated companies in the United States, including, as
examples, Eastman Kodak, Ford Motor Company, and Allstate Insurance Company.
CBC/Madison Advisory Group, through preferred service relationships, by
assisting major, multi-market companies in developing and executing real
estate strategies, by addressing specific occupancy and facilities management
objectives and by providing support for most of the functions involved in a
corporate real estate department. Strategic advisory services include
acquisition, disposition and consulting services. CBC/Madison Advisory Group
has been one of CBC's fastest growing services, with revenue having increased
at a compound annual rate of 50% from 1993 through 1996 (40% in the first
quarter of 1997).
 
  Property Management. Property management provides operations, maintenance,
marketing and leasing services for income-producing properties owned primarily
by institutional investors. CBC provides asset management-oriented services to
its clients to implement their specific goals and objectives, focusing on the
enhancement of property values through maximization of cash flow. As of March
31, 1997, CBC managed 810 properties aggregating approximately 109 million
square feet.
 
  Real Estate Market Research. CBC provides its research and forecasting
services to its other businesses as well as outside corporate and
institutional investor clients through CB Commercial/Torto Wheaton Research,
the widely-recognized research division of CBC based in Boston, Massachusetts.
CBC's research reports and forecasts are utilized by all of CBC's businesses
to assist clients with analysis and interpretation of market data in order to
provide them with a competitive edge in the rapidly changing real estate
marketplace.
 
INVESTOR SERVICES
 
  Investor Services includes mortgage banking (mortgage loan origination and
servicing), investment management and advisory services, and valuation and
appraisal services relating primarily to office space, industrial buildings,
retail properties, multifamily residential properties and unimproved land.
 
  Mortgage Banking. CBC provides its mortgage origination and servicing
through L.J. Melody & Company, a wholly-owned subsidiary of CBC acquired in
July 1996 and based in Houston, Texas. On a combined basis including
originations by L.J. Melody prior to its acquisition, CBC originated $3.25
billion, $2.3 billion and $2.0 billion of mortgage loans in 1996, 1995 and
1994, respectively. As part of these origination activities, CBC originates
mortgages through special conduit arrangements with affiliates of Merrill
Lynch, Citicorp, NationsBanc and Lehman Brothers which generally permit it to
service the mortgage loans that it originates. In addition, CBC is a major
mortgage originator for insurance companies having originated, on a combined
basis, mortgage loans in the names of such insurance companies valued at $1.7
billion in 1996. As of December 31, 1996, 1995 and 1994, CBC, on a combined
basis, serviced mortgage loan portfolios of $7.0 billion, $7.3 billion and
$7.1 billion, respectively. Based upon available statistics, CBC believes
that, on a combined basis, it is the largest independent commercial mortgage
originator in the United States. CBC believes it will have a significant
competitive advantage in the commercial mortgage loan origination business due
to its anticipated integration with the deal flow generated through CBC's
brokerage and investment properties sales activities. This integration will
not only provide advantages to mortgage banking, but will also facilitate
sales transactions enhancing CBC's capability to execute clients' sales
assignments.
 
                                      36
<PAGE>
 
  Investment Management and Advisory. CBC provides its investment management
and advisory services primarily to large institutions and pension funds
through Westmark Realty Advisor's ("Westmark") which employs approximately 100
professionals and operates nationally from its headquarters in Los Angeles,
California. Westmark operates as a separate and independent subsidiary,
providing as of December 31, 1996 advisory services to and managing
approximately $3.7 billion in tax-exempt capital invested in more than 215
office, industrial and retail properties located in more than 40 major U.S.
markets with an aggregate of more than 38 million square feet. CBC's
investment management and advisory activities include creating investment
products, raising investor capital, identifying and acquiring specific
properties and managing the operations and dispositions of the assets. As of
March 31, 1997, CBC represented more than 180 investors in 13 commingled funds
and a variety of nondiscretionarily managed separate accounts.
 
  Valuation and Appraisal Services. Valuation and appraisal services delivers
sophisticated commercial real estate valuations through a variety of products
including market value appraisals, portfolio valuations, discounted cash flow
analyses, litigation support, feasibility land use studies and fairness
opinions. CBC's appraisal staff has more than 80 professionals with more than
50% of its professionals holding the Member Appraisal Institute ("MAI")
professional designation. Valuation and appraisal services operates nationally
through 23 regional offices, and its clients are generally portfolio owners,
both corporate and institutional. CBC believes it is among the leading
commercial real estate appraisal firms in the United States.
 
  As part of its growth strategy, CBC is continually assessing acquisition
opportunities. Management believes that there are significant opportunities in
the fragmented and consolidating real estate services industry to acquire
additional companies to complement and expand CBC's existing operations. Since
the beginning of 1995, CBC has completed three strategic acquisitions. In July
1996, CBC acquired L.J. Melody & Company and L.J. Melody & Company of
California (collectively "L.J. Melody"), a nationally-known mortgage banking
firm, for $15  million. The L.J. Melody acquisition provided CBC with
leadership for its own mortgage banking business, access to loan sources not
previously available to CBC and an enhanced ability to access CBC's deal flow
in its investment properties and brokerage businesses as a source of mortgage
originations. In June 1995, CBC acquired Westmark Realty Advisors L.L.C.
("Westmark"), an investment management and advisory business with
approximately $3.0 billion of assets under management, for $37.5 million (plus
the assumption of debt) and a supplemental purchase price component of up to
$18.0 million based upon Westmark's adjusted operating income. The Company has
reached a non-binding, tentative agreement with the former owners of Westmark
to purchase their right to supplemental purchase price (a maximum of
approximately $15.3 million over the next four years) for $11.1 million in
cash and their right as employees to incentive compensation (a maximum of
approximately $3.2 million) for $2.4 million. The Westmark acquisition has
moved CBC into a business area which CBC believes has the potential for
significant growth although to date Westmark has not experienced that growth.
In April 1995, CBC acquired Langdon Rieder Corporation ("Langdon Rieder"), a
nationally-known tenant representation firm, for $1.5 million in cash and a
deferred payment of $1.9 million payable over three years ($633,333 of which
was paid on January 2, 1997, $633,333 of which is due on January 2, 1998 and
$633,333 of which is due on January 2, 1999). The deferred payment is subject
to forfeiture under certain circumstances. To date, no event of forfeiture has
occurred. The Langdon Rieder acquisition strengthened CBC's ability to provide
sophisticated tenant representation services to its corporate clients. The
KRES Merger is the next step in CBC's acquisition strategy.
 
  CBC's executive offices are located at 533 South Fremont Avenue, Los
Angeles, California 90071-1798 and its telephone number is (213) 613-3123.

                           KOLL REAL ESTATE SERVICES
 
  KRES is a fully-integrated real estate services company that provides
property, facility, investment management and brokerage services to
institutional and corporate owners of and investors in commercial real estate
in the United States and Asia. KRES' services include (i) property and
facilities management and leasing services for more than 3,500 commercial and
residential properties containing approximately 146 million square feet and
over 21,000 tenants, (ii) investment management for asset portfolios
consisting primarily of commercial real estate investments, which had an
aggregate cost basis of approximately $2 billion as of March 31, 1997 and
(iii) a variety of related services. KRES' approximately 2,600 employees
provide these services through a network of more than 260 offices.
 
  Since 1991, KRES has implemented an aggressive growth strategy through
acquisitions, having completed over 20 acquisitions during this period. From
April 1, 1991 through March 31, 1997 KRES increased the total square footage
it manages or leases from approximately 38 million square feet to
approximately 146 million square feet, (ii) established the Investment
Management Division, which manages portfolios of assets which had an aggregate
cost basis of approximately $2 billion at March 31, 1997, and (iii)
established related services which have been cross-marketed to KRES' new and
existing clients.
 
  Koll Management Services, Inc. ("KMS") was incorporated in California in
June 1988 and reincorporated in Delaware in May 1991. On July 31, 1991, KMS
completed an initial public offering of 1.1 million shares of its common stock
at $10 per share, which yielded net proceeds to KMS of $5.4 million. KMS was
traded on the Nasdaq National Market System under the symbol "KOLL." Prior to
its initial public offering, KMS was a wholly-owned subsidiary of The Koll
Company, a real estate development, construction and management company
founded in 1962 in Newport Beach, California, by Donald M. Koll, its Chairman.
In the years following the initial public offering, KMS' management did not
realize its expectation to issue additional debt or equity at favorable terms
in order to fund its strategy for growth through acquisitions and, as a
result, management supported the completion of a merger (the "KRES/KMS
Merger") in 1994. KRES was organized in May 1994 by Freeman Spogli & Co.
Incorporated ("FS&Co."), a private investment company, to effectuate the
KRES/KMS Merger and FS&Co's investment in KRES. On November 23, 1994, the
stockholders of KMS approved the KRES/KMS Merger pursuant to which each share
of KMS' common stock (other than shares held by KRES) was converted into the
right to receive $16.00. Upon consummation of the KRES/KMS Merger, KMS became
a wholly-owned subsidiary of KRES and KMS' common stock was no longer publicly
traded. In connection with the settlement of stockholder litigation
challenging the KRES/KMS Merger and the fairness of the consideration to be
received pursuant thereto, in September 1995 KMS paid its former stockholders
(other than KRES, The Koll Company and KMS former directors and officers) an
additional $0.50 per share for each share of KMS common stock held by such
stockholders and in January 1997 KRES paid a total of $22.50 per share for
25,000 shares of KMS Common Stock in settlement of an appraisal rights suit
relating to the KRES/KMS Merger. In August 1996, KRES filed a Registration
Statement in connection with a proposed initial public offering of its common
stock. However, due to a decline in market value of publicly-traded comparable
companies during the preparation of the Registration Statement and while the
Registration Statement was pending, KRES determined that the value to be
obtained from the proposed initial public offering and the dilution to
existing stockholders were unacceptable. KRES instead pursued a private
financing alternative which KRES considered to be a more cost effective
alternative to meet its financing needs and abandoned the proposed initial
public offering.
 
  KRES' principal executive offices are located at 4343 Von Karman Avenue,
Newport Beach, California 92660, and its telephone number is (714) 833-9360.

                     BACKGROUND AND REASONS FOR THE MERGER
 
BACKGROUND
 
  In August of 1995 CBC initiated potential merger discussions with KRES and
its major shareholder, FSEP III. The parties exchanged some confidential
information but could not reach agreement with respect to relative values. The
discussions were terminated in November of 1995. In December of 1996, James J.
Didion, CBC's Chairman and Chief Executive Officer, contacted Donald M. Koll,
founder and Chairman of the KRES Board, to determine if there was an interest
in pursuing merger discussions. Mr. Koll indicated that he had such an
interest and suggested that Mr. Didion contact Bradford Freeman, a principal
of FSEP III, the holder of a
 
                                      41
<PAGE>
 
majority of the outstanding stock of KRES. In early January of 1997, Mr.
Didion called Mr. Freeman, who also expressed an interest in pursuing merger
discussions. Over the course of the next two and one-half months,
representatives of CBC, FSEP III, KRES and AP KMS Partners and other major
KRES shareholders negotiated the basic terms of a merger. Those negotiations
were completed on March 18, 1997 when the parties signed a non-binding letter
of intent. Through March 18, 1997, no party had performed due diligence with
respect to CBC or KRES. The non-binding letter of intent provided that CBC
would issue a total of up to 6,148,256 shares of CBC Common for all of the
issued and outstanding stock of KRES (not to exceed 7,233,243 shares) and
would substitute options for CBC Common for various options for KRES Common
held by certain officers, directors and consultants of KRES. In the view of
CBC (but not necessarily in the view of KRES and its shareholders) this number
of shares was based upon figures provided by KRES with respect to the level of
its indebtedness and other obligations and its EBITDA for the 12-month period
ended December 31, 1996.
 
  From March 18, 1997 through May 13, 1997, CBC conducted due diligence with
respect to KRES and KRES and certain of its shareholders conducted due
diligence with respect to CBC. CBC conducted due diligence with an internal
team and a legal team consisting of personnel from Pillsbury Madison & Sutro
LLP. On May 14, 1997 CBC, KRES, FS Equity Partners, AP KMS Partners and
certain others signed a definitive agreement with respect to the Merger. The
definitive agreement reduced the number of shares of CBC Common to be issued
to not more than 5,614,261 shares but also provided for the issuance of
warrants with respect to 600,000 shares of CBC Common exercisable at a price
of $30.00 per share. The primary reasons for the reduction in the initial
number of shares to be issued were a difference between the way KRES and CBC
calculate EBITDA and an increase in the anticipated amount of KRES' bank
indebtedness and other obligations.
 
RECOMMENDATIONS OF THE CBC BOARD; REASONS FOR THE MERGER
 
  By unanimous vote of the directors present, the CBC Board approved the
Merger Agreement as being fair and in the best interest of CBC and its
stockholders. ACCORDINGLY THE CBC BOARD UNANIMOUSLY RECOMMENDS A VOTE IN FAVOR
OF THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY.
 
  The CBC Board believes that the Merger offers the potential for CBC to
improve profitability and capitalization through economies of scale, the
elimination of redundancies, access to additional capital and the enhancement
of market position. By consolidating certain operations and eliminating
duplicative expenses, CBC expects to achieve substantial savings of operating
costs. Such savings would be realized over time as consolidation is completed.
Realization of improvements in profitability is dependent, in part, on the
extent to which the revenues of CBC and KRES are maintained and will be
influenced by many factors, and there can be no assurance that cost savings
will be realized or that improvements in profitability will be achieved.
 
  Prior to entering into the Merger Agreement, CBC conducted a due diligence
review of KRES. The due diligence was conducted over a period of approximately
40 days by a CBC team which included Walter V. Stafford, CBC's General
Counsel, James J. Didion, CBC's Chief Executive Officer, John C. Haeckel,
CBC's Chief Financial Officer, and Ronald J. Platisha, CBC's Principal
Accounting Officer, and a legal team from CBC's outside law firm, Pillsbury
Madison & Sutro LLP.
 
  The primary function of the various due diligence teams was to review KRES'
operations, business practices, information technology, corporate structure,
contractual obligations, liabilities, financial position and other areas which
might be material to CBC in making its acquisition, both to help familiarize
CBC with KRES's business and to uncover any material problems. The CBC due
diligence team found no material problems as a result of the due diligence.
However some issues existed, including (i) a $5,250,000 payment KRES was
required to make in order to facilitate the buy out of the interest of a joint
venture partner, thereby terminating the joint venture agreement which would
have required CBC, after the Merger, to pay to such partner a portion of the
revenues it generated in the region in which the joint venture operated, (ii)
a small difference in the manner in which KRES computed EBITDA compared to the
manner in which CBC computed EBITDA, and (iii) KRES'
 
                                      42
<PAGE>
 
increased bank indebtedness (caused by increased operating expenses and
investments in new initiatives), the resolution of such issues resulted in a
small reduction in the number of shares of CBC Common issuable in connection
with the Merger.
   
  In making its determination, the CBC Board took into account the results of
CBC's due diligence review of KRES' business. In its presentation to the CBC
Board on April 22, 1997, CBC's management reported on the results of its due
diligence investigation of KRES. The due diligence team did not make any
formal findings but presented the results of it investigation and analyses to
the CBC Board. The results of the due diligence team's investigation and
analyses which were relied upon by the CBC Board included (i) verification of
the corporate data, business history, operations and properties of KRES, (ii)
verification of the contracts and commitments to which KRES was a party, (iii)
verification of the amounts and nature of indebtedness and other liabilities
of KRES and confirmation that these could be assumed by CBC, (iv) confirmation
that KRES had no material liabilities about which the CBC Board was previously
unaware, (v) confirmation that KRES' financial condition and results of
operations were substantially similar to what the CBC Board had believed them
to be prior to the conduct of the due diligence, (vi) the existence of
potential synergies resulting from the combined company and (vii) confirmation
that KRES' business practices, information technology and operations could be
successfully integrated with CBC's in a cost-effective manner. The due
diligence team related to the CBC Board the reasons for KRES' abandonment of
its proposed initial public offering as described above under "KOLL REAL
ESTATE SERVICES."     
 
  The terms of the Merger, the Merger Agreement and related agreements and the
Exchange Ratio resulted from arm's-length negotiations between management of
CBC and certain of the stockholders of KRES and their respective
representatives. In the course of reaching its decision to approve the Merger,
the Merger Agreement and related agreements, the CBC Board considered a number
of factors in addition to those discussed above, including the following:
 
  (i) the reports of the due diligence teams with respect to the business,
financial performance and condition, results of operations, liabilities and
prospects of KRES;
 
  (ii) the growth prospects of CBC preceding and following the Merger;
   
  (iii) the historical and projected financial results of CBC and KRES and the
possible synergies to be obtained from the Merger, including the CBC Board's
belief that the Merger provides the potential for CBC and KRES to compete more
effectively and improve their profitability through economies of scale, the
elimination of redundancies and the enhancement of market position (CBC
projected the financial results of the combined companies by combining the
calendar 1996 results of both companies, assuming $10 million in potential
synergies during the first year and $12 million during each year thereafter
and assuming a 8% growth rate in revenue and a 6% growth rate in costs for
each of the next four calendar years);     
 
  (iv) economic conditions and prospects for KRES in the markets in which it
operates, in light of the intensifying competitive pressures in the property,
facility and investment management industries;
 
  (v) the structure of the transaction, including the fact that CBC's
stockholders would retain approximately 74% of the equity of the combined
company;
 
  (vi) the proposed composition of CBC's and KRES' Board and management
following the Merger, including the fact that the current members of the CBC
Board would continue in such capacities (with the addition of four
representatives of KRES' shareholders which the CBC Board believed would
provide continuity and expertise during the integration of the two companies),
see "Management and Operations After the Merger";
 
  (vii) the terms of the Merger Agreement and other documents to be executed
in connection with the Merger;
 
  (viii) the belief that the business combination with KRES would offer
substantial long-term value to CBC's stockholders;
 
                                      43
<PAGE>
 
  (ix) the views of CBC's financial advisors and the opinion rendered by
Merrill Lynch to the effect that the Exchange Ratio was fair, from a financial
point of view;
 
  (x) the terms of other recent comparable combinations;
 
  (xi) the "intellectual capital" of the KRES management team and its
willingness to consider new initiatives and look at existing businesses from a
different perspective; and
 
  (xii) the employment and consulting contracts approved in connection with
the Merger. See "--Interests of Certain Persons in the Merger."
 
  In the course of its deliberations, the CBC Board also recognized a number
of potential disadvantages, including the following:
 
  (i) the Merger involves costs associated with its completion and the
operational consolidation of the two companies, which could adversely affect
the operating results of CBC;
 
  (ii) the Merger involves the dedication of substantial management resources;
 
  (iii) the highly competitive nature of the property management services
business;
 
  (iv) the matters described under "Risk Factors"; and
 
  (v) the potential loss of key KRES employees who do not want to be part of a
larger company or who are concerned that they will not be treated fairly in
relation to their CBC counterparts.
 
  The foregoing discussion of information and factors considered and given
weight by the CBC Board is not intended to be exhaustive but is intended to
set forth all material information related thereto. In view of the variety of
factors considered by the CBC Board in connection with its evaluation of the
Merger Agreement and the proposed Merger, the CBC Board did not find it
practicable to and did not quantify or otherwise assign relative weights to
the specific factors considered in reaching its determination and
recommendations. However, in their discussions the CBC Board and management
emphasized the possible synergies to be obtained from KRES' experience in
facility, property and asset management services with that of CBC. The CBC
Board concluded that these factors outweighed the potential disadvantages of
the Merger.
 
  In evaluating the recommendation of the CBC Board, stockholders should
carefully consider the matters described under "Risk Factors."
 
RECOMMENDATIONS OF THE KRES BOARD; REASONS FOR THE MERGER
 
  On May 2, 1997, the KRES Board approved the Merger Agreement and the
transactions contemplated thereby as being in the best interests of and fair
to KRES and its stockholders. ACCORDINGLY, THE KRES BOARD UNANIMOUSLY
RECOMMENDS A VOTE IN FAVOR OF THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY.
 
  In evaluating the Merger, the KRES Board considered and evaluated, among
other things, (i) the consideration offered by CBC for the outstanding shares
of KRES Common, (ii) the prospects for future growth in the value of CBC
Common, (iii) current economic, industry and market conditions affecting both
KRES and CBC, (iv) the position of both KRES and CBC in the markets and market
segments in which they compete, (v) the terms of the Merger Agreement, (vi)
the tax-free nature of the Merger, (vii) the potential opportunities and
challenges of combining the two organizations, (viii) the relinquishment of
control of KRES following the Merger and (ix) the potential disruption to
KRES' business operations in the event that the Merger is not consummated.
Because of the variety and complexity of the factors considered, the KRES
Board did not find it practicable to, and did not quantify or otherwise
attempt to assign relative weights to specific factors in reaching its
determinations.
 
                                      44
<PAGE>
 
  The KRES Board believes that the Merger offers the potential for improved
growth and profitability for the combined organization upon consummation of
the Merger. The KRES Board believes that there is the potential for
significant cost savings from consolidating duplicative operations and
functions and achieving economies of scale across a larger organization. In
addition, the KRES Board believes that the Merger offers potential for revenue
enhancement through cross-marketing of a broader array of services across a
larger customer base.
 
  The KRES Board believes that the CBC organization would be a complementary
strategic and cultural fit with the KRES organization. CBC's position as an
overall market leader, as well as its strengths in sales and leasing brokerage
and mortgage banking activities, would complement KRES' property, facilities
and asset management businesses. The newly-formed organization would benefit
from increased size and scope of operations in an increasingly competitive and
cost-sensitive marketplace. In addition, the Merger would combine CBC's
significant size, access to capital and longstanding market presence with
KRES' innovation, creativity and acquisition expertise. As CBC Common is
traded on the Nasdaq National Market, the Merger would offer KRES stockholders
enhanced liquidity, as KRES Common is not currently traded on any public
market. Finally, the KRES Board believes that KRES management would have a
significant ongoing role in the newly-formed organization.
 
  Based on the foregoing matters, the KRES Board believes that a number of
significant strategic benefits will accrue from the Merger that may be of
significant benefit to KRES, its employees and its stockholders. There can be
no assurance, however, that any or all of the benefits expected from the
Merger will be fully realized. In evaluating the recommendations of the KRES
Board, stockholders should carefully consider the matters described under
"Risk Factors."
 
                         OPINION OF FINANCIAL ADVISOR
 
  CBC retained Merrill Lynch to render an opinion to the Board of Directors
with respect to CBCs proposed business combination with KRES. On April 22,
1997, Merrill Lynch delivered its oral opinion, which opinion was subsequently
confirmed in a written opinion dated as of April 22, 1997, to the Board of
Directors of CBC to the effect that, as of such date, and based upon the
assumptions made, matters considered and limits of review set forth in such
opinion, the Transaction Consideration to be paid by CBC pursuant to the April
18, 1997 draft of the Merger Agreement (the "April Merger Agreement") is fair
to CBC from a financial point of view. References herein to the "Merrill Lynch
Opinion" refer to the written opinion of Merrill Lynch dated as of April 22,
1997.
 
  A copy of the Merrill Lynch Opinion, which sets forth the assumptions made,
matters considered and limitations on the scope of review undertaken by
Merrill Lynch, is attached to this Joint Proxy Statement/Prospectus as Annex
3. Stockholders of CBC are urged to read the Merrill Lynch Opinion in its
entirety. The Merrill Lynch Opinion is directed only to the fairness from a
financial point of view of the transaction consideration to be paid by CBC
pursuant to the April Merger Agreement. The Merrill Lynch Opinion does not
address the merits of the underlying decision of CBC to engage in the Merger
and does not constitute a recommendation to any stockholder of CBC as to how
such stockholder should vote. The summary of the Merrill Lynch Opinion set
forth in this Joint Proxy Statement/Prospectus is qualified in its entirety by
reference to the full text of such opinion.
 
  The Transaction Consideration to be paid by CBC was determined through
negotiations between CBC and KRES and was approved by their respective Boards
of Directors. Merrill Lynch was not retained to and did not consider any
alternative transactions or participate in the negotiations regarding the
Transaction Consideration. Merrill Lynch expressed no opinion as to the prices
at which the shares of CBC Common will trade following the announcement or
consummation of the Merger. Merrill Lynch's opinion is necessarily based upon
financial, economic, market and other conditions as they existed and could be
evaluated on, and the information made available to Merrill Lynch as of, the
date of the Merrill Lynch Opinion.
 
                                      45

  In arriving at the Merrill Lynch Opinion, Merrill Lynch, among other things,
(i) reviewed KRES's audited consolidated financial statements and related
financial information for the fiscal year ended March 31, 1996, the periods
from December 1, 1994 through March 31, 1995 and April 1, 1994 through
November 30, 1994, and the year ended March 31, 1994; KRES's related unaudited
financial information for the three years ended December 31, 1996; and KRES's
Registration Statement on Form S-1 filed with the Securities and Exchange
Commission; (ii) reviewed CBC's Annual Reports on Forms 10-K and related
financial information for the three fiscal years ended December 31, 1996;
CBC's quarterly reports on Forms 10-Q and the related unaudited financial
information for the quarterly periods ending March 31, 1996, June 30, 1996 and
September 30, 1996; and certain other of CBC's filings with the Securities and
Exchange Commission during the last three years, including certain reports on
Forms 8-K and its Registration Statement on Form S-1; (iii) reviewed certain
information, including financial forecasts, relating to the business,
earnings, cash flow, assets, liabilities and prospects of KRES and CBC, as
well as the synergies and the amount and timing of the related cost savings
and expenses expected to result from the Merger furnished to Merrill Lynch by
KRES and CBC, respectively; (iv) conducted discussions with members of senior
management and representatives of KRES and CBC concerning their respective
businesses and prospects, before and after giving effect to the Merger and the
expected operating benefits arising from the Merger; (v) reviewed the market
prices and valuation multiples for the shares of CBC Common and compared them
with those of certain publicly traded companies that Merrill Lynch deemed
relevant; (vi) reviewed the results of operations of KRES and CBC and compared
them with those of certain companies that Merrill Lynch deemed relevant; (vii)
reviewed, under applicable valuation methodologies, the theoretical valuation
of the Warrants to be issued pursuant to the April Merger Agreement; (viii)
compared the proposed financial terms of the Merger with the financial terms
of certain other transactions that Merrill Lynch deemed relevant; (ix)
reviewed the potential pro forma impact of the Merger on CBC's earnings, cash
flow and capitalization ratios; (x) reviewed a draft of the April Merger
Agreement; and (xi) reviewed such other financial studies and analyses and
took into account such other matters as Merrill Lynch deemed necessary,
including its assessment of general economic, market and monetary conditions.
 
  In preparing the Merrill Lynch Opinion, Merrill Lynch assumed and relied on
the accuracy and completeness of all financial and other information supplied
or otherwise made available to it or discussed with or reviewed by or for
Merrill Lynch or publicly available. Merrill Lynch did not assume any
responsibility for making any independent verification of such information or
for making any independent evaluation or appraisal of any of the assets or
liabilities of KRES or CBC, nor was Merrill Lynch furnished with any such
evaluation or appraisal. Merrill Lynch relied upon the estimates of the
managements of CBC and KRES of the synergies expected to result from the
Merger and assumed that such synergies will be achieved. Such synergies, which
relate to property management and other general and administrative expenses,
are expected to result in total pre-tax synergies of approximately $5 million
beginning in the six months ending 1997, $11 million for the calendar year
ending 1998 and $12 million for the calendar years ending 1999 and 2000. With
respect to the financial forecast information and the synergies and related
cost savings and expenses expected to result from the Merger furnished to or
discussed with Merrill Lynch by KRES and CBC, Merrill Lynch assumed that they
were reasonably prepared and reflected the best currently available estimates
and judgment of KRES's or CBC's management, as the case may be, as to the
expected future financial performance of KRES or CBC, as the case may be. In
addition, Merrill Lynch did not assume any obligation to conduct, nor did
Merrill Lynch conduct, any physical inspection of the properties or facilities
of KRES or CBC. Merrill Lynch also assumed that the Merger would be
consummated on terms substantially similar to those set forth in the draft of
the April Merger Agreement and that the Warrants to be issued as part of the
Transaction Consideration would contain terms not materially different from,
and otherwise in conformance with, those customary in similar transactions.
Merrill Lynch assumed in rendering its opinion, that the Merger will
constitute a reorganization within the meaning of section 368(a) of the Code.
 
  The aggregate consideration to be paid by CBC pursuant to the Merger
Agreement differs from the Transaction Consideration set forth in the April
Merger Agreement upon which the Merrill Lynch Opinion is based. In accordance
with the Transaction Consideration set forth in the April Merger Agreement,
each outstanding share of KRES Common would have been converted into the right
to receive (i) 0.79 shares of CBC Common and (ii) a Warrant exercisable into
0.0691 shares of CBC Common at an exercise price of $30.00 per
 
                                      46
<PAGE>
 
share (the "Warrant Consideration"); provided, that the number of shares of
CBC Common issuable upon exercise of the Warrants would not exceed 500,000
shares. Pursuant to the terms of the Merger Agreement, however, each
outstanding share of KRES Common would be converted into (i) 0.776175 shares
of CBC Common, subject to adjustment (including adjustments relating to
outstanding indebtedness of KRES upon consummation of the Merger), and (ii) a
number of Warrants, each exercisable into one share of CBC Common at an
exercise price of $30.00 per share, equal to (A) 600,000 divided by (B)(1) the
number of shares of KRES Common outstanding immediately prior to the Effective
Time of the Merger plus (2) the number of shares of KRES Common into which
outstanding options to purchase shares of KRES Common are exercisable at such
time (0.083238 Warrants per share of KRES Common based on an assumed aggregate
of 7,208,243 shares of KRES Common Stock outstanding and underlying such KRES
Options immediately prior to the Effective Time); provided, that the number of
shares of CBC Common issuable upon exercise of the warrants may not exceed
600,000 shares.
 
  The Merrill Lynch Opinion and the discussion set forth herein is based upon
the Transaction Consideration set forth in the April 18, 1997 draft of the
Merger Agreement. Merrill Lynch has informed CBC that, based upon the terms of
the final Merger Agreement dated May 14, 1997, it would not have modified its
opinion that the aggregate consideration to be paid by CBC in the Merger is
fair from a financial point of view to CBC. In reaching such determination,
Merrill Lynch did not undertake to review any documentation in addition to
that set forth in its opinion delivered to the CBC Board on April 22, 1997,
nor did Merrill Lynch provide the CBC Board with a formal opinion regarding
the fairness of the aggregate consideration as set forth in the final Merger
Agreement dated May 14, 1997.
 
  The following paragraphs contain a summary of certain of the financial and
comparative analyses performed by Merrill Lynch in arriving at its opinion to
the CBC Board dated as of April 22, 1997. The summary does not purport to be a
complete description of the analyses conducted by Merrill Lynch. The
preparation of a fairness opinion is a complex process involving the
application of complex methodologies and educated judgment that is not
necessarily susceptible to partial analysis or summary description. Merrill
Lynch believes that its analyses must be considered as a whole and that
selecting portions of its analyses and the factors considered by it, without
considering all such analyses and factors, could create an incomplete view of
the process underlying its opinion. Merrill Lynch did not assign relative
weights to any of its analyses in preparing its opinion, but rather made
qualitative judgments and estimates that it considered reasonable and
appropriate under the circumstances as to the significance and relevance of
each analysis and factor. In addition, the matters considered by Merrill Lynch
in arriving at the Merrill Lynch Opinion are based on numerous macroeconomic,
operating and financial assumptions with respect to industry performance,
general business and economic conditions, many of which are beyond the control
of KRES and CBC. Any estimates incorporated in the analyses performed by
Merrill Lynch are not necessarily indicative of actual past or future results
or values, which may be significantly more or less favorable than such
estimates. Estimated values do not purport to be appraisals and do not
necessarily reflect the prices at which businesses or companies may be sold in
the future, and such estimates are inherently subject to uncertainty.
Accordingly, neither Merrill Lynch nor any other person assumes responsibility
for their accuracy.
 
  Stock Trading History. Merrill Lynch examined the history of trading prices
and volume for the shares of CBC Common and the Standard & Poors Composite
Average of 500 industrial companies in relation to each other and the
relationship between price movements thereof. Since CBC's initial public
offering in November 1996, shares of CBC Common have traded as high as $27 3/8
per share and as low as $18 per share. The closing price of a share of CBC
Common on March 4, March 11, and March 17, 1997, two weeks, one week and
immediately prior to announcement of the Merger, respectively, was $23 1/2,
$23 3/4 and $24 1/2, respectively.
 
  Warrant Valuation. Merrill Lynch used "Black-Scholes" and binomial option
pricing models to value the Warrants based upon the terms set forth in the
April Merger Agreement. Based upon such models and using other valuation
parameters, including assumptions for interest rates and volatility factors,
the Warrants were attributed a theoretical value of approximately $4,700,000,
for a total implied exchange ratio, together with the CBC Common, of 0.82 per
share.

  Comparable Public Companies Analysis. Merrill Lynch compared certain
financial and operating information and ratios for KRES and CBC with
corresponding publicly available financial and operating information and
ratios for a group of publicly traded companies that Merrill Lynch deemed to
be relevant. The companies reviewed included Amresco Inc. ("Amresco"), Grubb &
Ellis Company, Insignia Financial Group, Inc. ("Insignia") and CBC (only with
respect to KRES) (collectively, the "Comparables"). These companies were
selected, among other reasons, because they operate in one or more of the
market segments and businesses in which KRES and CBC operate. Merrill Lynch's
calculations resulted in the following relevant valuation ranges based in each
case upon its analysis of those Comparables that it deemed most relevant to
the respective comparison and, in the case of KRES, relied primarily upon
information regarding CBC: (i) total enterprise value (defined as the market
value of common equity plus book value of total debt and preferred stock less
cash) as a multiple of latest twelve months ("LTM") revenue (as of
December 31, 1996) of 0.7x to 0.9x for CBC (with CBC at 0.88x) and 0.9x to
1.5x for KRES; (ii) total enterprise value as a multiple of LTM (as of
December 31, 1996) earnings before interest taxes, depreciation and
amortization ("EBITDA") of 7.3x to 8.3x for CBC (with CBC at 7.8x) and 7.3x to
8.3x for KRES; (iii) total market value of common equity as a multiple of LTM
(as of December 31, 1996) cash earnings (defined as EBITDA less interest less
cash provision for taxes) of 9.0x to 10.0x for CBC (with CBC at 9.5x); and
(iv) total market value of common equity as a multiple of projected calendar
1997 net income of 16.0x to 20.0x for CBC (with CBC at 20.6x). Applying the
ranges of multiples derived from Merrill Lynch's analysis of the financial
information of those Comparables deemed most relevant by Merrill Lynch,
Merrill Lynch calculated implied per share equity values of CBC ranging from
$20.89 to $25.63, and of KRES ranging from $14.45 to $19.98, for an implied
exchange ratio range of .56 to .96 (adjusted for the Warrant Consideration,
the implied exchange ratio range is .59 to .99).
 
  None of the companies utilized in the above analysis for comparative
purposes is, of course, identical to CBC or KRES. Accordingly, a complete
analysis of the results of the foregoing calculations cannot be limited to a
quantitative review of such results and involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the Comparables and other factors that could affect the public trading value
of the Comparables.
 
  Comparable Acquisition Analysis. Merrill Lynch also reviewed the
consideration paid and financial terms of seven transactions involving real
estate services companies (the "Comparable Acquisitions"). The Comparable
Acquisitions reviewed, in reverse chronological order of announcement date,
were: (i) the pending acquisition by Apartment Investment and Management
Company of NHP, Incorporated (not yet approved by stockholders); (ii) the
acquisition by CBC of L.J. Melody & Company (an acquisition by the
registrant); (iii) the acquisition by Insignia Financial of Edward S. Gordon
Company; (iv) the acquisition by HFS Incorporated of Coldwell Banker; (v) the
acquisition by HFS, Inc. of Century 21 Real Estate Corporation; (vi) the
acquisition by CBC of Westmark Realty Advisors (an acquisition by the
registrant); and (vii) the acquisition by Amresco of Holliday Fenoglio &
Company. Merrill Lynch analyzed the offer value and transaction consideration
multiples implied by the prices paid in these transactions. The calculations
resulted in the following relevant ranges, based in each case on Merrill
Lynch's analysis of those Comparable Acquisitions that it deemed most relevant
to the respective comparison: offer value (defined as the offer price per
share multiplied by the sum of the number of shares outstanding and the number
of exercisable options outstanding less proceeds resulting from the exercise
of the options) as a multiple of LTM cash earnings of 9.0x to 12.0x for CBC;
transaction value (defined as offer value plus the book value of total debt
and preferred stock assumed less cash) as a multiple of EBITDA of 7.0x to
10.0x for CBC and KRES; and transaction value as a multiple of LTM revenue of
0.8x to 1.0x for CBC and 1.0x to 1.6x for KRES. Applying the ranges of
multiples derived from Merrill Lynch's analysis of the financial information
of those Comparable Acquisitions deemed most relevant by Merrill Lynch,
Merrill Lynch calculated implied per share equity values of CBC ranging from
$20.89 to $29.77, and of KRES ranging from $14.45 to $22.74, for an implied
exchange ratio range of .49 to 1.09 (adjusted for the Warrant Consideration,
the implied exchange ratio range is .51 to 1.12).
 
  No transaction utilized in the comparable acquisition transaction analysis
was identical to the Merger. Accordingly, an analysis of the results of the
foregoing is not purely mathematical. Rather, it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies
 
                                      48
<PAGE>
 
included in the comparable acquisition transaction analysis and other factors
that could affect the offer value and the transaction consideration.
 
  Discounted Cash Flow Analysis. Merrill Lynch also performed discounted cash
flow analyses (i.e., an analysis of the present value for the projected
unlevered free cash flows and terminal value for the periods and at the
discount rates indicated) of both CBC and KRES for the years 1997 through
2002, inclusive, using discount rates reflecting a weighted average cost of
capital ranging from 12.0% to 14.0% and terminal value multiples of calendar
year 2002 EBITDA ranging from 7.0x to 9.0x. Applying the results of such
discounted cash flow analysis, and assuming no synergies arising out of the
Merger, Merrill Lynch calculated implied per share equity values of CBC
ranging from $27.23 to $38.05, and of KRES ranging from $16.04 to $23.04, for
an implied exchange ratio range of .42 to .85 (adjusted for the Warrant
Consideration, the implied exchange ratio range is .44 to .87). Applying the
same results but assuming synergies arising out of the Merger in pre-tax
annual amounts of $5 million beginning in the six months ending December 31,
1997, $11 million for the calendar year ending 1998, and $12 million for the
calendar years ending 1999 to 2002, Merrill Lynch calculated implied per share
equity values of CBC ranging from $29.42 to $41.00, and of KRES ranging from
$20.00 to $28.25 for an implied exchange ratio range of .49 to .96 (adjusted
for the Warrant Consideration, the implied exchange ratio range is .50 to
 .98).
 
  Contribution Analysis. Merrill Lynch analyzed CBC's relative contribution to
the combined company with respect to revenues, EBITDA and net income at and
for the pro forma fiscal year ended December 31, 1996. The pro forma
information for the combined company was based on the actual fiscal year ended
December 31, 1996 results for CBC and KRES. As a result of the Merger, CBC's
stockholders will own approximately 73.9% of the equity of the combined
company. This compares with CBC's contribution to the combined company's pro
forma results, without taking into account any synergies, of approximately
82.4% of revenues, 79.1% of EBITDA and 94.3% of net income. Merrill Lynch also
calculated the relative contributions to the combined company's estimated 1997
and 1998 EBITDA, giving full effect to the expected synergies. CBC's
contribution to the combined company's estimated 1997 and 1998 EBITDA is 71.2%
and 70.7%, respectively, excluding 9.7% and 10.4% in contribution attributable
to expected synergies, respectively.
 
  Pro Forma Merger Analysis. Merrill Lynch analyzed certain pro forma effects
resulting from the Merger, including the potential impact of the Merger on
projected earnings per share ("EPS") and EBITDA for the combined company, and
in each such case, with and without expected synergies. In its analysis,
Merrill Lynch assumed that the Merger was treated as a purchase for accounting
purposes and excluded any one-time restructuring charges that may result from
the Merger. With synergies, the Merger would be accretive on an EPS and EBITDA
basis to the holders of CBC Common immediately and for the three calendar
years ended December 31, 2000. Without taking into account expected synergies,
the Merger would be dilutive to the holders of CBC Common for the same
periods.
 
  The CBC Board selected Merrill Lynch to render a fairness opinion not only
on the basis of Merrill Lynch's reputation as an internationally recognized
investment banking firm with substantial expertise in transactions similar to
the Merger but also on the basis of its familiarity with CBC and CBC's
business. As part of its investment banking business, Merrill Lynch is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions. For Merrill Lynch's services, CBC
has agreed to pay Merrill Lynch a fee of $500,000 upon the delivery of Merrill
Lynch's written fairness opinion. CBC also agreed to reimburse Merrill Lynch
for certain reasonable out-of-pocket expenses (including reasonable fees and
expenses of its legal counsel) incurred in connection with its engagement and
to indemnify Merrill Lynch and certain related persons against certain
liabilities, including liabilities under securities laws, arising out of its
engagement. CBC further agreed that, if it determines to pursue an
underwritten offering of equity securities in connection with the Merger, CBC
will offer to retain Merrill Lynch to act as lead underwriter.
 
  Merrill Lynch has also performed various investment banking services for
KRES and CBC in the past and has received customary fees for such services. In
the ordinary course of its securities business, Merrill Lynch may actively
trade equity securities of CBC for its own account and the accounts of its
customers, and Merrill Lynch therefore may hold a long or short position in
such securities.

                        MATERIAL EFFECTS OF THE MERGER
 
GENERAL EFFECTS
 
  Upon consummation of the Merger, KRES will become a wholly-owned subsidiary
of CBC, and CBC will immediately contribute the stock of KRES to CBC Group,
CBC's principal operating subsidiary. Acquisition Corporation will cease to
exist as a separate corporate entity, and holders of KRES Common (other than
those holders exercising appraisal rights) at the time and on the date an
agreement of merger is filed with the Delaware Secretary of State will receive
(i) a number of shares of CBC Common equal to the Stock Exchange Ratio
multiplied by the number of shares of KRES Common held by each KRES
stockholder as of the Effective Time and (ii) Warrants for a number of shares
of CBC Common equal to the Warrant Exchange Ratio multiplied by the number of
shares of KRES Common held by each KRES stockholder as of the Effective Time.
The KRES Options will be exchanged for equivalent options to purchase CBC
Common and individual holders of KRES Options who are directors, employees or
consultants of KRES or certain of its subsidiaries immediately prior to the
Effective Time will receive Warrants for a number of shares of CBC Common
equal to the Warrant Exchange Ratio multiplied by the number of shares of KRES
Common into which such KRES Options are exercisable. See "THE MERGER--Merger
Consideration" and "--Effect on Employee Benefit and Stock Plans." After the
Merger, the present holders of KRES Common will hold approximately 5.6 million
shares of CBC Common which will represent approximately 30% of the CBC Common
then outstanding (assuming no conversion of the Preferred Stock), and CBC will
hold 100% of the KRES Common then outstanding. In terms of voting rights, the
present holders of KRES Common will hold approximately 26% of all voting
rights. KRES stockholders who receive stock of CBC Common pursuant to the
Merger and will be stockholders of CBC, a Delaware corporation. See
"COMPARISON OF THE RIGHTS OF HOLDERS OF CBC COMMON AND KRES COMMON." CBC
intends to contribute the KRES Common to CBC Group, its principal operating
subsidiary, immediately after the Merger.
 
MATERIAL FEDERAL INCOME TAX CONSIDERATIONS
 
  The Merger is intended to constitute a tax-free reorganization within the
meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal Revenue Code
of 1986, as amended (the "Code"), with the following material federal income
tax consequences:
 
  (a) No gain or loss will be recognized by KRES stockholders upon the receipt
of CBC Common in exchange for their KRES Common;
 
  (b) The aggregate basis of the CBC Common received by a KRES stockholder
will be the same as the aggregate basis of the KRES Common surrendered in
exchange therefor, subject to adjustment as discussed below if the Warrants
are treated as property other than stock or securities;
 
  (c) A KRES stockholder's holding period for the CBC Common received in
exchange for KRES Common will include the period during which such KRES Common
was held, provided that such KRES Common is a capital asset at the Effective
Time;
 
  (d) A KRES stockholder receiving cash in the exchange in lieu of a
fractional interest in CBC Common will be treated as if such stockholder
actually received such fractional share interest, and such fractional interest
was subsequently redeemed by CBC; and
 
  Consummation of the Merger is conditioned upon delivery of an opinion to
KRES from Riordan & McKinzie, counsel to KRES, that, based upon assumptions
and understandings contained in the opinion, the Merger will constitute a
reorganization within the meaning of Code Sections 368(a)(1)(A) and
368(a)(2)(E), and no gain or loss will be recognized by KRES and the KRES
stockholders as a result of the receipt of CBC Common. Subject to the
discussions below and the taxability of cash in lieu of fractional share
interests mentioned above, CBC and KRES believe that these assumptions and
understandings are reasonable and that such an opinion will be delivered at
the closing of the Merger.
 
                                      50
<PAGE>
 
  Existing Income Tax Regulation sections promulgated under sections 354 and
355 of the Code treat the Warrants as neither stock nor securities for
reorganization purposes. However, under applicable case law preceding such
regulations, the Warrants could be treated as securities for reorganization
purposes. In December, 1996, the Department of the Treasury proposed Income
Tax Regulations which treat the Warrants as securities without a principal
amount. As presently drafted, such regulation would apply to exchanges
occurring on or after sixty (60) days following its adoption. Thus, at the
present time, it is not clear whether the Warrants received by the KRES
stockholders will be treated for reorganization purposes as securities or as
property other than stock or securities. Regardless of whether the Warrants
constitute securities for reorganization purposes, no gain or loss will be
recognized by KRES, Acquisition Corporation or CBC as a result of the issuance
of the Warrants.
 
  If the Warrants are treated for reorganization purposes as securities as
provided in the proposed Income Tax Regulations, the following material
federal income tax consequences will result in connection with the Warrants:
 
    (a) No gain or loss will be recognized by KRES stockholders upon receipt
  of Warrants in the Merger exchange;
 
    (b) The basis of a KRES stockholder in the Warrants received in the
  Merger will equal zero; and
 
    (c) A KRES stockholder's holding period for the Warrants received in
  exchange for KRES Common will include the period during which such KRES
  Common was held by such KRES stockholder; provided that such KRES Common is
  a capital asset at the Effective Time.
 
  If, however, the Warrants are treated as other than stock or securities as
set forth in the existing Income Tax Regulations, the following material
federal income tax consequences will result in connection with the Warrants:
 
    (a) KRES stockholders will recognize gain upon receipt of Warrants in the
  Merger exchange in an amount equal to the lesser of (i) the excess of the
  fair market value of the CBC Common and Warrants received over the basis of
  such KRES stockholder in the KRES Common exchanged in the Merger, or
  (ii) the fair market value of such Warrants received in the Merger;
 
    (b) the basis of a KRES stockholder in the Warrants will equal the fair
  market value of such Warrants;
 
    (c) The aggregate basis of the CBC Common received by a KRES stockholder
  will be the same as the aggregate basis of the KRES Common surrendered in
  exchange therefor decreased by the fair market value of any Warrants
  received by such KRES stockholder and increased by the amount of gain such
  KRES stockholder recognizes upon receipt of Warrants; and
 
    (d) A KRES stockholder's holding period for the Warrants received in
  exchange for KRES Common will commence on the day following receipt of such
  Warrants.
 
  No gain or loss will be recognized by a holder of an unexercised option to
acquire KRES Common solely as a result of the conversion of such option into
an option to acquire CBC Common, provided that (i) the option to acquire KRES
Common was issued in connection with the performance of services and (ii)
neither the option to acquire KRES Common nor the option to acquire CBC Common
had or has a readily ascertainable fair market value (within the meaning of
Income Tax Regulations Section 1.83-7(b)) when issued or at the Effective
Time.
 
  A KRES stockholder who perfects dissenters' rights and receives payment for
such stockholder's KRES Common will be treated as if such stock was redeemed.
In general, if the KRES Common is held as a capital asset at the Effective
Time, a dissenting stockholder will recognize a capital gain or loss measured
by the difference between the amount of cash received and the basis of the
KRES Common. However, if such dissenting KRES stockholder owns, directly or
constructively through application of Section 318 of the Code, any KRES Common
as to which dissenters' rights are not exercised and perfected and which are
therefore exchanged for
 
                                      51
<PAGE>
 
CBC Common in the Merger, such stockholder may be treated as having received a
dividend in the amount of cash paid to the stockholder in exchange for the
shares as to which dissenters' rights are perfected. Under Section 318 of the
Code, an individual is deemed to own stock that is actually owned (or deemed
to be owned) by certain members of such individual's family (spouse, children,
grandchildren and parents, with certain exceptions) and other related parties,
including, for example, certain entities in which the individual has a direct
or indirect interest (such as partnerships, estates, trusts and corporations),
as well as stock that such individual (or a related person) has the right to
acquire upon exercise of an option or conversion right held by such individual
(or related person). Each KRES stockholder who intends to dissent from the
Merger (see "Appraisal Rights") should consult such stockholder's own tax
advisor with respect to the application of the constructive ownership rules to
the stockholder's particular circumstances as well as with regard to the 20
percent federal backup withholding which may become applicable to the gross
proceeds realized in respect of KRES Common of a dissenter failing either to
furnish its federal taxpayer identification number as requested by KRES or its
transfer agent or to otherwise establish an exemption from such withholding.
 
  The foregoing is not intended to be a comprehensive discussion of all
possible federal income tax consequences of the Merger. Furthermore, this
Joint Proxy Statement/Prospectus does not provide information about the tax
consequences of the Merger under the tax laws of any state or of any local or
foreign jurisdiction or with respect to any KRES stockholder who is a dealer
in securities, who is a foreign person or who acquired KRES Common in
connection with the performance of services.
 
         KRES STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
              WITH RESPECT TO ALL TAX CONSEQUENCES OF THE MERGER
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for by CBC under the purchase method of
accounting in accordance with Accounting Principles Board Opinion No. 16,
"Business Combinations" ("APB No. 16"). Under this method of accounting, the
purchase price will be allocated to assets acquired and liabilities assumed
based on their estimated fair values at the Effective Time. After the
Effective Time, CBC will include KRES' results using the consolidation method
of accounting.
 
EXCHANGE ACT REQUIREMENTS
 
  CBC Common is currently registered under the Exchange Act. Following the
Merger, CBC, so long as it is subject to Section 13(a) or 15(d) of the
Exchange Act, will have an obligation to file annual, quarterly and other
periodic reports with the Commission, which will include consolidated
financial and other information regarding CBC and its subsidiaries. Directors,
officers and 10% stockholders of CBC will continue to be subject to the short-
swing profit recovery provisions of Section 16(b) of the Exchange Act and all
other applicable provisions of the federal and state securities laws with
respect to transactions in CBC equity securities. CBC Common will continue to
be quoted on the Nasdaq National Market. CBC is considering listing the CBC
Common on the New York Stock Exchange rather than on Nasdaq and on May 20,
1997 CBC's Board unanimously approved such a listing at the time selected by
CBC's Chief Executive Officer. CBC currently intends to list on the New York
Stock Exchange and to delist from the Nasdaq before the end of 1997.
 
                        OPERATIONS FOLLOWING THE MERGER
 
  Following the Merger, the stock of KRES will be contributed to CBC Group and
KRES will become a wholly-owned subsidiary of CBC Group. Other than as
described below, it is the present intention of CBC to operate CBC in
substantially the same manner following the Merger as currently being
operated. Initially, CBC intends to continue to operate the subsidiaries of
KRES under their existing names but a majority of them are expected to be
liquidated or merged into another subsidiary by the end of 1997.
 
                                      52
<PAGE>
 
  Consolidation of Operations. The property management, facilities management,
brokerage and corporate services functions of KRES will not be continued in
KRES but rather will be integrated into the businesses of CBC Group. In terms
of business practices, CBC Group intends to adopt the best business practices
of each company. The asset management/pension advisory business of KRES
generally will be maintained as a separate business and will not be combined
with the asset management/pension advisory services of Westmark, a wholly-
owned subsidiary of CBC Group. The mortgage banking business of KRES will be
integrated into the mortgage banking business of L.J. Melody & Company, a
wholly-owned subsidiary of CBC Group. CBC Group's international operations are
largely conducted through alliances with third parties whereas KRES has
operated internationally through joint ventures in which it takes a material
interest and plays a significant role. No decisions have been made with
respect to the integration of international operations.
 
  Consolidation of Certain Corporate Functions. CBC and KRES believe the
combined companies will be able to realize certain cost savings and
operational efficiencies following the Merger by consolidating various
corporate functions currently being conducted separately by CBC and KRES
(accounting, personnel, legal and corporate) and by eliminating certain
duplicative administrative functions.
   
  New CBC Officers. Following the Merger and the integration and pursuant to
the Merger Agreement, Raymond E. Wirta will be appointed President--Capital
Markets of CBC and William E. Rothe will be appointed a Senior Executive Vice
President of CBC with primary responsibility (with another CBC Senior
Executive Vice President) for the integration of CBC and KRES. See "Interests
of Certain Persons in the Merger--KRES Management." Other current officers of
KRES will retain their current employment arrangements but with CBC Group,
rather than KRES.     
 
  KRES Management. Following the Merger, the executive officers of KRES will
be (i) James J. Didion, Chief Executive Officer, (ii) John C. Haeckel, Chief
Financial Officer and Treasurer and (iii) Walter V. Stafford, Secretary and
General Counsel. For general information regarding such individuals, their
compensation and certain relationships and related transactions, see "SELECTED
INFORMATION REGARDING CBC."
 
  KRES Board of Directors. Pursuant to the Merger Agreement, CBC, as sole
stockholder of KRES, will take appropriate action such that, promptly
following the Merger, the KRES Board will be modified and James J. Didion,
John C. Haeckel and Walter V. Stafford will constitute the KRES Board, all of
such directors to serve until their successors are duly elected and qualified.

                                  THE MERGER
 
  The terms and conditions of the Merger are set forth in the Merger Agreement
attached to this Joint Proxy Statement/Prospectus as Annex 1 and incorporated
herein by reference. The following summary of the Merger Agreement does not
purport to be complete and is qualified in its entirety by reference to the
text of the Merger Agreement.
 
GENERAL; MERGER CONSIDERATION
 
  Under the terms of the Merger Agreement, if approved by the stockholders of
CBC and KRES and if all other conditions set forth in the Merger Agreement are
satisfied or waived, Acquisition Corporation, a wholly owned subsidiary of
CBC, will be merged into KRES, the separate corporate existence of Acquisition
Corporation will cease, and KRES as the surviving corporation will become a
wholly owned subsidiary of CBC. At the Effective Time, each holder of KRES
Common (other than those exercising appraisal rights) will receive (i) a
number of shares of CBC Common equal to the Stock Exchange Ratio multiplied by
the number of shares of KRES Common held by such KRES stockholder as of the
Effective Time and (ii) 0.083238 Warrants (based on an assumed aggregate of
7,208,243 shares of KRES Common Stock outstanding and underlying such KRES
Options immediately prior to the Effective Time) multiplied by the number of
shares of KRES Common held by such KRES stockholder as of the Effective Time.
The holders of CBC Common will continue to hold CBC Common following the
Merger. The outstanding options granted by KRES to purchase KRES Common ("KRES
Options") will be exchanged for equivalent options ("New Options") to purchase
CBC Common. In addition, holders of KRES Options who are directors, employees
or consultants of KRES or a subsidiary of KRES at the Effective Time will
receive a number of Warrants equal to 0.083238 (based on an assumed aggregate
of 7,208,243 shares of KRES Common Stock outstanding and underlying such KRES
Options immediately prior to the Effective Time) multiplied by the number of
shares of KRES Common into which such holder's KRES options are exercisable.
The number of shares of CBC Common issued in connection with the Merger will
not exceed 5,614,261 (including shares of CBC Common underlying CBC Options
issued in exchange for KRES Options), and the number of shares into which the
Warrants are exercisable will not exceed 600,000. See "THE MERGER--Effect on
Employee Benefit and Stock Plans."
 
  Warrants issuable pursuant to the Merger are exercisable into shares of CBC
Common at an exercise price of $30.00 per share of CBC Common. In addition,
each Warrant shall have a term of 7 years from the Closing Date, shall become
exercisable on the third anniversary of the Closing Date and shall be subject
to the terms and conditions of a Warrant Agreement to be entered into by and
among CBC, Acquisition Corporation and the Shareholders of KRES as of the
Closing Date. Those Warrants issued in respect of KRES Options are subject to
forfeiture and reallocation under certain circumstances. See "THE MERGER--
Adjustments to Merger Consideration."
 
ADJUSTMENTS TO MERGER CONSIDERATION
 
  If, between the date of the Merger Agreement and the Effective Time, the
outstanding shares of CBC Common or KRES Common shall have been changed into a
different number of shares or a different class by reason of any
reclassification, recapitalization, split-up, combination, exchange of shares
or readjustment, the Stock Exchange Ratio shall be correspondingly adjusted.
In addition, for each $100,000 by which Bank Indebtedness exceeds $47,375,000
or by which any subcategory of Bank Indebtedness exceeds the applicable
sublimit set forth in the Merger Agreement (but without duplication), in both
cases as of the Closing Date, the Stock Exchange Ratio shall be reduced,
without limitation, by 0.0005883. Bank Indebtedness includes the aggregate
amount of indebtedness owed to banks or other lending institutions by KRES and
its subsidiaries and, in certain cases, any entity with respect to which KRES
or its subsidiaries has a material investment or is subject to unlimited
liability as a general partner or otherwise, and any entity which 50% of the
ownership interests having the power to elect the board of directors of such
entity is directly or indirectly controlled by any of the foregoing.
 
 
                                      54
<PAGE>
 
  Following the Effective Time and until the Warrants first become
exercisable, if any New Option expires or is terminated without being
exercised, all Warrants issued in respect of the KRES Options for which such
New Option was exchanged shall be forfeited by the holder thereof. At such
time as the Warrants become exercisable, all Warrants forfeited pursuant to
the immediately preceding sentence shall be reallocated among those
individuals who held shares of KRES Common or KRES Options as of the date of
the Merger Agreement (each a "Reallocation Holder" and collectively, the
"Reallocation Holders") pro rata based on the aggregate number of shares of
the CBC Common issued and shares of CBC Common underlying New Options issued
to each Reallocation Holder pursuant to the Merger Agreement divided by the
total number of shares of CBC Common issued and shares of CBC Common
underlying New Options issued to all Reallocation Holders pursuant to the
Merger Agreement.
 
EFFECTIVE TIME
 
  The Merger will become effective upon the filing of a Certificate of Merger
with the Secretary of State of the State of Delaware. The filing with respect
to the Merger will occur as soon as practicable, but not more than one
business day following the later of (i) the approval of the Merger by CBC's
and KRES' stockholders at the CBC Meeting and the KRES Meeting, and (ii)
satisfaction (or waiver by the party whose satisfaction is required) of each
of the conditions precedent set forth in the Merger Agreement unless another
date is agreed to in writing by CBC, Acquisition Corporation and KRES.
Assuming all other conditions to the Merger are satisfied or waived, it is
anticipated that the filing will occur promptly after approval by the
stockholders of CBC and KRES.
 
EXCHANGE OF CERTIFICATES
 
  At or prior to the Closing, each holder of shares of KRES Common wishing to
exchange its shares will surrender the certificate(s) (each, a "Certificate")
representing such shareholder's shares of KRES Common to CBC. No service
charges, brokerage commissions or transfer taxes will be payable by
stockholders in connection with the Merger. After the Effective Time, there
will be no further registration of transfers on the stock transfer books of
KRES.
 
  Upon surrender of a Certificate for cancellation to CBC, the holder of such
Certificate shall be entitled to receive in exchange therefor shares of CBC
Common, payments in lieu of fractional shares and a Warrant as set forth in
the Merger Agreement. In the event of a transfer of ownership of KRES Common
which is not registered in the transfer records of KRES, the appropriate
number of shares of CBC Common and the appropriate Warrant may be delivered to
a transferee if the Certificate representing the right to receive such CBC
Common is presented to CBC and accompanied by all documents required to
evidence and effect such transfer and to evidence that any applicable stock
transfer taxes have been paid.
 
  Until surrendered as contemplated by the Merger Agreement, each Certificate
shall be deemed at any time after the Effective Time to represent the right to
receive upon such surrender the number of shares of CBC Common as provided by
the Merger Agreement and the Delaware General Corporation Law.
 
FRACTIONAL SHARES
 
  Pursuant to the Merger Agreement, no certificates for fractional interests
in shares of CBC Common will be issued pursuant to the Merger. In lieu of
certificates representing such fractional interests, each holder of KRES
Common whose shares are not convertible into a whole number of shares of CBC
Common shall be entitled to receive, upon surrender of such holder's
Certificates formerly representing KRES Common for exchange as provided above,
an amount of cash (without interest and rounded up to the nearest whole cent)
determined by multiplying such fractional interest by the average closing sale
price for CBC Common for the ten most recent trading days ending on the
trading day immediately prior to the Effective Time, as reported on the Nasdaq
National Market.
 
                                      55
<PAGE>
 
STOCK EXCHANGE LISTING
 
  It is a condition to KRES' and the KRES Shareholders' respective obligations
to consummate the Merger that all appropriate action shall have been taken for
listing the shares of CBC Common to be received in the Merger on the Nasdaq
National Market. CBC has agreed to take all appropriate actions to cause such
shares of CBC Common to be issued in the Merger to be so listed.
 
EXPENSES
 
  The Merger Agreement provides, in general, that CBC shall pay the reasonable
fees and expenses incurred incident to the preparation and carrying out of the
transactions contemplated by the Merger Agreement (including legal, accounting
and investment banking services and travel) provided, however, that the
aggregate amount payable by CBC and KRES for all fees and expenses of all
legal counsel to KRES and the KRES Shareholders shall not exceed $500,000 and
any amount payable in excess of such amount for fees and expenses of legal
counsel of KRES and the KRES Shareholders shall be payable by the KRES
Shareholders. The Merger Agreement further provides that CBC shall pay all
government filing fees and the costs of printing, filing and mailing this
Joint Proxy Statement/Prospectus (collectively, the "Filing Fees"). The Merger
Agreement also provides that, notwithstanding the foregoing, (i) KRES shall
bear all the Filing Fees and all reasonable fees and expenses (including
without limitation, fees and expenses payable to counsel to CBC, outside
consultants, accountants and to all investment banking firms and their
respective counsel) actually incurred by CBC and Acquisition Corporation in
the event that KRES' stockholders fail to approve the Merger by that date
which is twenty (20) days after the effective date of the Registration
Statement or shareholders of KRES holding over 100,000 shares exercise
dissenter's rights and (ii) if the transactions contemplated by the Merger
Agreement are not consummated by October 31, 1997, each party to the Merger
Agreement shall be responsible for its own fees and expenses and KRES and the
KRES Shareholders shall promptly reimburse CBC for any amounts advanced,
reimbursed or otherwise paid to them by CBC to cover fees and expenses
pursuant to the Merger Agreement.
 
EFFECT ON EMPLOYEE BENEFIT AND STOCK PLANS
 
  All employee pension benefit plans, welfare benefit plans and other plans or
programs maintained or to which contributions are made for the benefit of
current or former employees of KRES or any of its subsidiaries, as in effect
immediately prior to the Effective Time are expected to be determined after
Effective Time and CBC will substitute its plans or programs which may or may
not be comparable to those of KRES.
 
  Following the Effective Time, the outstanding KRES Options issued to
directors, employees or consultants of KRES who are directors, employees or
consultants of KRES or its subsidiaries immediately prior to the Effective
Time shall be replaced with New Options to purchase the number of shares of
CBC Common equal to the Stock Exchange Ratio multiplied by the number of
shares of KRES Common previously covered by the KRES Option, rounded down to
the nearest whole number of shares of CBC Common. The exercise price for each
such share of CBC Common under the New Option shall be equal to the exercise
price for each share of KRES Common divided by the Exchange Ratio, rounded up
to the nearest whole cent. Each such New Option shall otherwise have
substantially the same terms and conditions as the KRES Options had
immediately prior to the Effective Time. CBC has reserved a sufficient number
of shares of CBC Common for issuance upon exercise of the New Options. CBC has
also agreed to use its reasonable best efforts to file a registration
statement on Form S-8 at or prior to the Effective Time that will cover the
shares of CBC Common issuable upon exercise of the New Options.

NO SOLICITATION OF TRANSACTIONS
 
  The Merger Agreement provides that neither KRES, its subsidiaries nor the
KRES Shareholders will, directly or indirectly through any officer, director,
employee, representative or agent: solicit, initiate or encourage inquiries or
the submission of proposals or offers from any third party relating to any
Acquisition Transaction or participate in any discussions or negotiations
regarding or furnish third parties with any confidential information with
respect to, or otherwise cooperate with, participate in, facilitate or agree
to endorse or encourage any attempt to do any of the foregoing. The Merger
Agreement provides that KRES and the KRES Shareholders shall promptly advise
CBC (orally and in writing) of any such inquiry or proposal, or contacts with
third parties for any such Acquisition Transaction and the details thereof and
not accept (nor shall KRES' board of directors or any committee thereof
recommend) any such proposal or offer. "Acquisition Transaction" means any
acquisition or purchase of all or substantially all of the business,
properties or assets of, or any equity interest in, KRES or certain of its
subsidiaries or any merger, consolidation, business combination or similar

transactions contemplated by the Merger Agreement, the sale by KRES' auction
subsidiary of certain assets to which it takes title in the ordinary course of
its business and certain scheduled items.
 
INDEMNIFICATION
 
  Pursuant to the Merger Agreement, CBC and Acquisition Corporation, its
wholly-owned subsidiary, have agreed to indemnify certain individuals against
claims made against them by reason of the fact that they were officers or
directors of KRES or certain of its subsidiaries prior to the Effective Time,
to the same degree CBC currently indemnifies its own directors and officers.
 
  A limited number of representations and warranties made by the KRES
Shareholders and CBC, respectively, survive the Effective Time and the Merger
Agreement provides that claims for indemnity may be made for breaches thereof.
 
  The representations and warranties of the KRES Shareholders which survive
the Effective Time relate to (i) title to their shares of KRES Common and
their authority to sell such shares and enter into the Merger Agreement, which
are of unlimited duration, (ii) the absence of certain undisclosed liabilities
on KRES' March 31, 1997 balance sheet, which survive for one year after the
Effective Time and (iii) no KRES Shareholder having knowingly furnished any
information to CBC in writing pursuant to the Merger Agreement, at any time
prior to the Effective Time, which contained or will contain any untrue
statement of a material fact or omitted or will omit to state any material
fact necessary to make any statement, in light of the circumstances under
which such statement is made, not misleading, which survive for one year after
the Effective Time.
 
  With respect to breaches of the representation described in clause (i)
above, each KRES Shareholder is liable for all damages caused by a breach of
such representation by such KRES Shareholder. The KRES Shareholders are not
responsible for any losses caused by a breach of the representations described
in clauses (ii) and (iii), above, until the aggregate amount of all such
losses exceeds $2,000,000, at which time they are responsible for all such
losses (including the first $2,000,000). With respect to breaches of the
representation described in clause (ii), the maximum aggregate amount for
which the KRES Shareholders may be liable is $17,500,000 and no KRES
Shareholder may be liable for any amount in excess of its pro rata share of
all such losses. With respect to breaches of the representation described in
(iii), a KRES Shareholder shall only be liable if it knowingly furnished the
information which caused the breach or knew that KRES or another KRES
Shareholder furnished such information and all KRES Shareholders with such
knowledge shall be jointly and severally liable. In addition, KRES
Shareholders breaching the representation described in (iii) shall forfeit all
options exercisable into CBC Common which they hold other than those issued in
connection with the Merger. No KRES Shareholder shall be liable for breaches
of the representations described in clauses (ii) and (iii) for any amount in
excess of the total value of the CBC Common and New Options received by such
KRES Shareholder.
 
                                      59
<PAGE>
 
  The representations and warranties of CBC which survive the Effective Time
relate to (i) authority to enter into the Merger Agreement and (ii) the due
authorization, valid issuance, fully paid and nonassessable nature of the
shares of CBC Common issued in the Merger and that such shares are not subject
to any preemptive rights, each of which is of unlimited duration. CBC has
agreed to indemnify the KRES Shareholders against all damages arising from a
breach of such representations.
 
ADDITIONAL AGREEMENTS
 
  The Merger Agreement contains additional covenants including, among others,
(i) KRES has agreed to and to cause its accountants to afford to CBC and its
representatives access to KRES and certain of its subsidiaries properties,
books, contacts, commitments and records and to its accountants' work papers,
(ii) each party has agreed to take all reasonable actions to comply with all
legal requirements which may be imposed with respect to the Merger and to
obtain any consents and approvals (or exemptions) of any governmental
authority or other third party required to be obtained by such party or its
subsidiaries; (iii) KRES and CBC have each agreed to submit the Merger
Agreement and related matters to its respective stockholders for approval;
(iv) each of KRES and CBC have agreed not to furnish information relating to
the Merger to the public without the consent of the other; (v) each party to
the Merger Agreement has agreed to act in good faith to cause all the
conditions precedent to its obligations under the Merger Agreement to be
satisfied; (vi) each party to the Merger Agreement has agreed to take all
reasonably necessary actions such that the Merger will be treated as a tax-
free reorganization and (vi) each party to the Merger Agreement has agreed to
update its disclosures made thereunder as to any material fact arising between
the date of the Merger Agreement and the Closing Date.
 
  In addition to its agreements set forth in the first paragraph of this
section, CBC has agreed, among other matters, to (i) take the actions
described in "THE MERGER--Effect on Employee Benefits and Stock Plans" and
(ii) cause its Board of Directors to be constituted as described in
"Operations Following the Merger--Board of Directors."
 
  In addition to its agreements set forth in the first paragraph of this
section, KRES has agreed, among other matters to (i) furnish CBC with the
name, address and number of shares of KRES Common held by any dissenting
stockholder, (ii) make certain payments to CBC in the event that CBC or one of
its subsidiaries is unable to participate as a broker with respect to the sale
of certain properties held by certain investment partnerships in which KRES or
one of its subsidiaries has an interest and (iii) identify those persons who
are its "affiliates" for purposes of Rule 145 under the Securities Act, and to
use its best efforts to cause such persons to agree not dispose of shares
received by them in connection with the Merger except in compliance with the
Securities Act. See "CERTAIN OTHER AGREEMENTS--Affiliates Agreements."

subsidiaries, taken as a whole or CBC and its subsidiaries, taken as a whole,
respectively.
 
  (iii) No temporary restraining order, preliminary injunction or permanent

material portion of the business or assets of KRES and such subsidiaries or
CBC and its subsidiaries, in each case taken as a whole, or compel CBC and its
subsidiaries or KRES or certain of its subsidiaries to dispose of or hold

  (viii) by CBC if any of the following events occur:
 
    (A) KRES or the KRES Shareholders advise CBC (or either is obligated
  under the Merger Agreement to advise CBC but has failed to do so) that KRES
  or any KRES Shareholder has been advised in writing by counsel that it is
  required to participate in negotiations, provide information, or otherwise
  cooperate with any corporation, partnership, person or other entity or
  group (as defined in Section 13(d) of the Exchange Act) (other than KRES or
  an affiliate of KRES) (a "Third Party") concerning an Acquisition
  Transaction
 
                                      62
<PAGE>
 
  and KRES intends to proceed with such action or any KRES Shareholder

  certain of its subsidiaries), any KRES Shareholder or any of their
  respective directors, officers or agents, directly or indirectly, solicits
  or initiates any discussions relating to an Acquisition Transaction;
 
    (B) KRES shall have adopted, approved or implemented or taken any action
  in respect of or entered into an agreement with respect to, any plan of
  liquidation or commenced or undertaken, any restructuring or
  recapitalization plan which contemplates the disposition or distribution,
  directly or indirectly, of any material amount of assets or securities of
  KRES to some or all of its securityholders either by dividend, share
  purchase, exchange offer, reclassification, merger, exchange or otherwise;
  or
 
    (C) KRES' Board of Directors or any committee thereof shall have
  withdrawn, or amended or modified in any manner adverse to CBC or
  Acquisition Corporation, its approval or recommendation of this Agreement
  or the Merger or taken any position inconsistent with such approval or
  recommendation or shall have recommended another Acquisition Transaction or
  resolved to do any of the foregoing.
 
  (ix) by CBC if any condition to CBC's obligation to complete the Merger has
not been satisfied or waived by CBC;
 
  (x) by KRES if any condition to KRES' obligation to complete the Merger has
not been satisfied or waived by KRES;
 
  (xi) by KRES if CBC shall have failed to obtain the consent of its primary
lender by June 2, 1997; and
 
  (xii) by CBC if KRES and certain of its subsidiaries shall have incurred
Bank Indebtedness in amounts in excess of those permitted by the Merger
Agreement and the incurrence of such additional Bank Indebtedness shall have
had a material adverse effect on KRES and certain of its subsidiaries, taken
as a whole.
 
  The occurrence of any event referred to in clause (viii) above is referred
to herein as a "Third Party Transaction."
 
  In the event of termination of the Merger Agreement by CBC or KRES, the
Merger Agreement and the Certificate of Merger will become void and there will
be no liability or obligation on the part of CBC or KRES or their respective
officers or directors other than under certain specified provisions of the
Merger Agreement dealing with confidentiality agreements, indemnification
provisions and the payment of expenses and other than liabilities or damages
incurred or suffered by a party as a result of the breach by the other party
of any of its representations, warranties, covenants or agreements set forth
in the Merger Agreement.
 
  In the event that CBC terminates the Merger Agreement due to the occurrence
of a Third Party Transaction, then KRES, within one day of notice from CBC,
shall pay to CBC in cash or immediately available funds (i) a termination fee
of $5,000,000 and (ii) an amount equal to all Filing Fees paid by CBC or
Acquisition Corporation and all fees and expenses actually incurred by CBC and
Acquisition Corporation in connection with the Merger Agreement and the
transactions contemplated thereby (including without limitation, fees and
expenses payable to counsel to CBC, outside consultants, accountants and to
all investment banking firms and their respective counsel).
 
AMENDMENT AND WAIVER
 
  The Merger Agreement may be amended at any time by an instrument in writing
signed by all the parties thereto, except that after the Merger has been
approved by the stockholders of CBC, Acquisition Corporation or KRES, no
amendment may be entered into which requires further approval by such
stockholders unless such further approval is obtained. In addition, any party
to the Merger Agreement by appropriate corporate or other action, to the
extent legally allowed, may extend the time for performance of the obligations
of the other parties to the Merger Agreement, waive inaccuracies in
representations and warranties and waive compliance with any agreements or
conditions for their respective benefit contained in the Merger Agreement.

                           CERTAIN OTHER AGREEMENTS
 
VOTING AGREEMENTS AND PROXY AGREEMENTS
 
  In connection with the Merger Agreement, CBC and Acquisition Corporation
entered into a Voting Agreement (the "KRES Voting Agreement") and Proxy
Agreements (the "Proxy Agreements") dated May 14, 1997 with FS, AP KMS II, LLC
and AP KMS Partners, L.P., Koll Holding Company, Raymond E. Wirta and William
S. Rothe, who are either stockholders of KRES or hold options to purchase KRES
Common. Mr. Wirta is also a director and officer of KRES and Mr. Rothe is also
an officer of KRES. As of May 31, 1997, such stockholders and optionholders
held in the aggregate approximately 96.7% of the currently outstanding KRES
Common (approximately 91.1% on a fully diluted basis) and options to purchase
115,000 shares of KRES Common. The remaining 31 shareholders and optionholders
of KRES who, as of May 31, 1997, held approximately 3.3% of the outstanding
KRES Common (approximately 8.9% on a fully diluted basis) and options to
purchase 417,500 shares of KRES Common are not parties to the Voting Agreement
with CBC. Only stockholders are entitled to vote, optionholders have no voting
rights. See "SELECTED INFORMATION WITH RESPECT TO KRES--Ownership of KRES
Common." No consideration was paid to such entities or individuals in
connection with the Voting Agreement or Proxy Agreements.
 
  Pursuant to the KRES Voting Agreement and Proxy Agreements, each such
stockholder and optionholder agreed to vote its or his shares of KRES Common
(a) in favor of the Merger pursuant to the Merger Agreement and any
transaction reasonably necessary or appropriate to implement the Merger, (b)
in opposition to any proposal for the amendment of KRES' Certificate or Bylaws
inconsistent with the Merger and the Merger Agreement and (c) other than
pursuant to the Merger and the Merger Agreement, in opposition to any proposal
for any merger or other business combination, consolidation, sale or purchase
of any assets, reorganization, recapitalization, liquidation or winding up of
or by KRES or any of its subsidiaries or affiliates or any offer or sale of
any substantial equity interest in or all or a substantial portion of the
stock or assets of, KRES or any of its subsidiaries or affiliates. Each such
stockholder and optionholder also granted CBC irrevocable proxies to vote all
KRES Common held by them in favor of the Merger Agreement. Such stockholders
and optionholders also agreed that they will not make, solicit, or encourage
any offers relating to, or engage in negotiations with, or furnish any
nonpublic information relating to KRES or its subsidiaries or affiliates to,
any third person with regard to any merger or other business combination,
acquisition of a substantial portion of the assets or equity interest in, KRES
or its subsidiaries or affiliates, other than any transaction contemplated by
the Merger Agreement. Each such stockholder or optionholder of KRES further
agreed not to take any action to prevent the consummation of the Merger
pursuant to the Merger Agreement.
 
  Pursuant to the KRES Voting Agreement, FS also agreed that prior to the
Effective Time of the Merger, with certain exceptions, it will not take any
action, directly or indirectly, in connection with (a) the election or removal
of directors or any change in the current composition of the Board of
Directors of KRES, or (b) any amendment to KRES' Certificate of Incorporation,
Bylaws or other constitutive documents relating to the constitution of a
quorum of directors or stockholders necessary for a meeting, or the number or
voting rights of stockholders or directors. FS further agreed to take all
lawful action to maintain the current number, voting rights and composition of
the Board of Directors of KRES.
 
  The foregoing summary of the Voting Agreement and Proxy Agreements does not
purport to be complete and is qualified in its entirety by reference to the
Voting Agreement and Proxy Agreements, copies of which are included in the
Registration Statement relating to this Joint Proxy Statement/Prospectus. See
"AVAILABLE INFORMATION."
 
AFFILIATES AGREEMENTS
 
  The CBC Common to be issued pursuant to the Merger will be freely
transferable under the Securities Act, except for shares issued to any person
who is an "affiliate" of CBC or KRES within the meaning of Rules 144 and 145
under the Securities Act. Rules 144 and 145 impose restrictions on the manner
in which such affiliates
 
                                      64
<PAGE>
 
may resell securities and also on the quantity of securities that such
affiliates and others with whom they might act in concert may resell within
any three-month period.
 
  On May 14, 1997, each person who may be deemed to be an affiliate of KRES
entered into an agreement with CBC providing that such person will not offer
to sell or otherwise dispose of any CBC Common obtained as a result of the
Merger except in compliance with the Securities Act and the rules and
regulations thereunder or otherwise represented to CBC individually or through
counsel that such person is aware of the restrictions contained in such rules
and regulations. Generally this will require that such sales be made in
accordance with Rule 145(d) under the Securities Act. Rule 145(d) generally
requires that (i) for specified periods, such sales be made in compliance with
the volume limitations, manner of sale provisions and current information
requirements of Rule 144 under the Securities Act or (ii) such person is not
an affiliate of CBC, and at least one year has elapsed since the date the CBC
Common was acquired as a result of the Merger and CBC is in compliance with
the current information requirements of Rule 144 or (iii) such person is not,
and has not been for at least three months, an affiliate of CBC, and a period
of at least two years has elapsed since the date the CBC Common was acquired
as a result of the Merger. The volume limitations should not pose any material
limitations on any CBC stockholder who owns less than one percent of the
outstanding CBC Common after the Merger unless pursuant to Rule 144, such
stockholder's shares are required to be aggregated with those of another
stockholder.
 
                  INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
KRES MANAGEMENT
 
  To assure the retention of key executives of KRES, CBC has entered into an
employment agreement with William S. Rothe, KRES' President and into a
consulting agreement with Donald M. Koll, KRES' Chairman of the Board.
 
  Following the Merger, pursuant to such employment agreement between CBC and
Mr. Rothe, which becomes effective at the Effective Time of the Merger (the
"Effective Date"), Mr. Rothe will serve as Senior Executive Vice President of
CBC. Pursuant to this employment agreement, Mr. Rothe will resign from each
and every position and office which he holds with KRES, KMS or any wholly-
owned subsidiary of either of them as of the Effective Date. Mr. Rothe's
compensation will consist of (i) base annual salary in the amount of $325,000
which will be reviewed from time to time by CBC but will not be made less than
$325,000, (ii) participation in an annual incentive compensation program which
may entitle him to an annual bonus equal to, less than or greater than one
hundred percent of his salary (with a $175,000 guaranteed bonus during the
first year of the employment agreement) and (iii) the grant of a ten year
stock option for 100,000 shares of CBC Common at an exercise price of $22.75
per share. The option vests as to one-third of the shares on the third
anniversary of the Effective Time, as to two-thirds on the fourth anniversary
and as to all of the shares on the fifth anniversary of the Effective Time.
Upon any termination of employment, Mr. Rothe will forfeit all unvested
shares. Mr. Rothe's employment agreement has a term of two years from the
Effective Time of the Merger. In addition options on identical terms to Mr.
Rothe's were granted to Mr. Wirta (100,000 shares), Richard Abraham (50,000
shares) and Richard Wollack (50,000 shares) in connection with their retention
as employees of CBC.
 
  Pursuant to a consulting agreement between CBC and Mr. Koll which also
becomes effective at the Effective Time, Mr. Koll will serve as a consultant
to CBC and shall be deemed an independent contractor. Mr. Koll's compensation
will consist of (i) base salary of $12,500 per month and (ii) the grant of a
stock option to purchase 250,000 shares of CBC Common for an exercise price of
$36.75 per share which will be fully vested as of the Effective Date but will
terminate one year after the consulting agreement is terminated. Mr. Koll's
consulting agreement has a term of one year from the Effective Time of the
Merger.
 
KRES DIRECTORS
 
  Following the Effective Time, James J. Didion, John C. Haeckel and Walter V.
Stafford will constitute the KRES Board, and will serve until their successors
are duly elected and assume office. Messrs. Didion, Haeckel
 
                                      65
<PAGE>
 
and Stafford are currently directors and executive officers of CBC. See
"SELECTED INFORMATION REGARDING CBC--Directors and Executive Officers" and
"Operations Following the Merger."
 
  Directors of KRES and certain of their affiliates are currently subject
(other than with respect to the surrender of KRES Common in exchange for CBC
Common pursuant to the Merger) to certain volume limitations imposed by Rule
144 under the Securities Act which restrict the number of shares of KRES
Common that each may transfer at any given time, and such directors and
affiliates will continue to be subject to similar restrictions under Rule 144
and/or Rule 145 of the Securities Act with respect to shares of CBC Common
held following the Merger. Because of the larger number of CBC shares
outstanding, one effect of the Merger is that certain affiliates may be
allowed to sell or transfer a greater number of shares in a single transaction
than would be possible prior to the Merger.
 
PROPOSED CBC DIRECTORS
 
  Following the Merger, so long as certain KRES shareholders who are
signatories to the Merger Agreement (collectively, the "KRES Shareholders")
hold shares equal to 60% of the shares originally issued to them pursuant to
the Merger Agreement, three individuals selected by such shareholders (and
reasonably satisfactory to the Corporate Governance Committee of the CBC
Board) shall be nominated for election to the CBC Board. For so long as they
are employed or engaged by CBC two of those individuals will be Raymond E.
Wirta and Donald M. Koll, current KRES directors. In addition to the three
directors referred to above, following the Effective Time and until the
election of directors to CBC's Board first following the Effective Time, CBC
will cause one individual selected by AP KMS II, LLC and reasonably
satisfactory to the Corporate Governance Committee of CBC's Board to be
nominated for election to CBC's Board. In the event that the KRES Shareholders
no longer hold shares equal to 60% of the shares originally issued to them
pursuant to the Merger Agreement, so long as FS owns 60% of the shares
originally issued to FS pursuant to the Merger Agreement CBC will cause one
individual selected by FS and reasonably satisfactory to CBC to be nominated
for election to CBC's Board. At the CBC Meeting, holders of CBC Common, CBC A-
1 Preferred and CBC A-2 Preferred will vote on the election of 19 Director
nominees, and CBC currently expects that all of its nominees for directors to
CBC's Board will be elected at the CBC Meeting. Donald M. Koll, Raymond Wirta,
Bradford M. Freeman and Ricardo Koenigsberger have been nominated for election
to CBC's Board at the CBC Meeting in the event the Merger is approved. See
"PROPOSAL FOR NOMINATION AND ELECTION OF CBC DIRECTORS".
 
STOCK OPTIONS
 
  Pursuant to the Merger Agreement, CBC will assume each KRES Option
outstanding under a KRES option plan held by an individual who is a director,
employee or consultant of KRES or its subsidiaries immediately prior to the
Effective Time by substituting a CBC Option for each such KRES Option. Each
CBC Option that is substituted by CBC will continue to be subject to
substantially the same terms and conditions set forth in the KRES options
plans, except that (i) such CBC Options will be exercisable for that number of
whole shares of CBC Common equal to the product of the number of shares of
KRES Common that were purchasable under such KRES Options immediately prior to
the Effective Time multiplied by the Stock Exchange Ratio, and (ii) the per
share exercise price for the shares of CBC Common issuable upon exercise of
such CBC Option will be equal to the quotient determined by dividing the
exercise price per share of KRES Common at which such KRES Option was
exercisable immediately prior to the Effective Time by the Stock Exchange
Ratio. Following the Effective Time, each such individual entitled to receive
a CBC Option will receive a Warrant for a number of shares of CBC Common equal
to the Warrant Exchange Ratio multiplied by the number of shares of KRES
Common into which such KRES Option is exercisable. As of May 31, 1997, there
were outstanding options to purchase 532,500 shares of KRES Common. See "THE
MERGER--Effect on Employee Benefit and Stock Plans."

(1) The financial data for KRES reflect the effects of the KRES/KMS Merger and
    as a result are not comparable to the financial data for Koll Management
    Services, Inc. (the Predecessor Company) prior to the Merger.
 
(2) A significant component of KRES' revenue is transactional in nature which
    is subject to certain seasonality. Historically, KRES' revenue, operating
    income and net income in the first and fourth quarters of its fiscal years
    are generally lower than in the second and third quarters due to these
    fluctuations, which is consistent with industry trends. Therefore,
    quarterly results are not necessarily representative of results for the
    entire year.
 
(3) See Note 1 of Notes to KRES Consolidated Financial Statements.
 
(4) EBITDA represents earnings before interest, income taxes, depreciation and
    amortization, thereby removing the effect of certain non-cash charges on
    income, consisting of depreciation and the amortization of intangible
    assets relating to acquisitions. Non-cash compensation expense under stock
    award plans of $329,000 for the period ending December 31, 1996, certain
    other non-recurring items including compensation expense related to the
    KRES/KMS merger of $1,208,000 for the eight months ending November 30,
    1994 and recognition of certain costs related to KRES' IPO effort and the
    unexpended loan fees related to the previous credit facility repaid in
    January 1997 of $1,390,000 for the period ending March 31, 1997 are
    included as expenses which have the effect of reducing EBITDA.
 
  Management believes that the presentation of EBITDA will enhance a reader's
  understanding of KRES' operating performance and ability to service debt as
  it provides a measure of cash generated that can be used by KRES to service
  its debt and for other required or discretionary purposes. Management has
  used EBITDA as one of the primary measures of operating performance in
  evaluating its recent acquisitions. EBITDA should not be considered as an
  alternative either (i) to operating income (determined in accordance with
  generally accepted accounting principles ("GAAP")), or (ii) operating cash
  flow (determined in accordance with GAAP). The measure entitled "EBITDA"
  may not be comparable to similarly entitled measures reported by other
  companies.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF KRES
 
 Introduction
 
  KRES' revenue is derived primarily from services provided by KRES' Property
and Corporate Services Division and Investment Management Division ("Fee Based
Services") and includes property and investment management fees, reimbursement
for expenses related to management personnel, leasing and other transaction
commissions (net of related commissions paid to others), construction
management fees and auction commissions. KRES' revenue is based in large part
on property management fees which are directly related to the level of rents
collected at the properties. For the last several years, occupancy and rental
rates across the country have generally been either stable or increasing. In
addition, a significant component of KRES' revenue is transactional in nature
and seasonal. Historically, this seasonality has caused KRES' revenue,
operating income and net income in the first and second calendar quarters to
be generally lower than in the third and fourth calendar quarters, which is
consistent with industry trends. See "RISK FACTORS--Seasonality." Therefore,
quarterly results are not necessarily representative of results for an entire
year or for any future period. Costs and expenses of Fee Based Services are
generally those costs incurred directly in connection with KRES' management of
properties and assets, in addition to the costs associated with the operations
of KRES' regional offices. Under the terms of KRES' typical property and
facilities management contract, a significant portion of the direct management
costs are reimbursed. Such reimbursement is included in revenue.
 
  Since April 1, 1991, KRES has implemented an aggressive growth plan as it
has continued its strategy of solidifying its position as a leading fully-
integrated real estate services company. The growth reflected in KRES'
financial statements is the result principally of acquisitions of real estate
service companies, internal growth from new assignments from existing and
first-time clients and new business initiatives, including capital markets and
Asian operations. KRES' acquisition program has focused on (i) regional
property management companies in strategically-targeted markets,
(ii) investment management companies and (iii) other complementary service
providers. Since April 1, 1991, KRES has completed more than 20 acquisitions
for an aggregate purchase price in excess of $45.0 million, the most
significant of which (based on revenue and net income) were: The Shelard
Group, Inc. ("Shelard"), Ross-Dove Company, Inc. ("Ross-Dove"), CBS Investment
Realty, Inc. ("CBS"), Karsten Realty Advisors ("Karsten") and Rubloff Inc.
("Rubloff"). Other acquisitions that were strategically significant include
National Real Estate Index ("NREI") and The Peregrine White Company, Inc.
("Peregrine White").
 
  KRES' administrative costs represent the costs of KRES' corporate management
and the various overhead departments including accounting, human resources,
payroll and management information services. In 1996 these
administrative costs grew at a more rapid pace than revenues and this trend
continued into the first calendar quarter of 1997. As a result of KRES'
acquisition and new initiatives strategy, KRES has experienced increased
overhead costs in the areas of corporate accounting, human resources and
management information services and higher start-up costs associated with the
new growth initiatives. As a result of these cost increases, KRES' recent
financial performance has been less profitable than in prior periods.
Management believes, however, that KRES will realize increased revenues in the
future as a result of its growth strategy to date. In the event that such
revenue increases do not materialize as anticipated, management believes that
it can reduce the current level of spending associated with its growth
strategy.
 
THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THREE MONTHS ENDED MARCH 31,
1996
 
  Revenue from Property and Corporate Services Division. The majority of this
division's revenue is recurring base contract fees and direct cost
reimbursement. Other revenue includes commissions from leasing
and property sales transactions net of related commissions paid to others.
Revenue of $28.0 million for the quarter ended March 31, 1997 increased $3.4
million (13.8%) as compared to revenue of $24.6 million for the quarter ended
March 31, 1996 primarily due to revenue from new facilities management
contracts. Revenue from the international operations had also increased over
the prior quarterly period, however, the increase was partially offset by a
decrease in base fee and onsite revenue under property management contracts.
 
                                      70

  Revenue from the Investment Management Division. Investment management
revenue is generated by recurring base investment management fees and contract
incentive fees related to the achievement of investment yields in excess of
base amounts stipulated in various of KRES' investment management contracts.
Other components of revenue include fees associated with the acquisition and
disposition of real estate assets on behalf of clients. Revenue of $4.9 million
for the quarter ended March 31, 1997 increased $700,000 (16.7%) as compared to
revenue of $4.2 million for the quarter ended March 31, 1996. This increase was
attributable to an increase in incentive fees earned under an investment
management contract.
 
  Costs of Property and Corporate Services Division. Costs and expenses of this
division's Fee Based Services are primarily salaries and wages incurred in
connection with the management of properties and associated with the division's
regional administrative offices. Costs of $22.1 million for the quarter ended
March 31, 1997 increased $4.0 million (22.1%) as compared to costs of $18.1
million for the quarter ended March 31, 1996. This increase is primarily
attributable to reimbursable costs and expenses related to new facilities
management contracts and increased investment spending related to growing KRES'
international operations from three to seven offices in Asia.
 
  Costs of the Investment Management Division. Costs and expenses of this
division's Fee Based Services are primarily salaries and wages incurred in
connection with providing investment advisory and management services. Costs of
$3.6 million for the quarter ended March 31, 1997 increased $1.4 million
(63.6%) as compared to costs of $2.2 million for the quarter ended March 31,
1996. This increase is primarily due to additional acquisition costs related to
new investment fund formation and costs related to new growth initiatives in
the real estate securitization industry, which are being pursued by KRES.
 
  Gross Operating Margin. KRES' total fee based margin declined to 21.9% from
29.6% of revenue for the quarters ended March 31, 1997 and 1996, respectively,
due primarily to higher reimbursable costs and expenses related to new
facilities management contracts, and additional acquisition costs for new
investment fund formation and new initiatives within the Investment Management
Division.
   
  Depreciation Expense. Depreciation expense is computed using the straight-
line method over estimated useful lives ranging from three to seven years on
capital assets such as computer hardware, software, office furniture and
equipment and leasehold improvements. Depreciation expense of $700,000 for the
quarter ended March 31, 1997 increased $165,000 (30.8%) as compared to $535,000
for the quarter ended March 31, 1996 primarily as a result of additional
investments in computer hardware and software.     
 
  Corporate Expenses. Corporate expenses represent costs incurred by the
various corporate overhead departments, as well as net expenses incurred in
operating the temporary services, employee-relations consulting, risk
management, training, human resources, and management information services
departments, unallocated depreciation and amortization, gains and losses on the
sale of KRES' investments, and interest income. Expenses of $5.5 million for
the quarter ended March 31, 1997 increased $3.7 million (205.6%) as compared to
expenses of $1.8 million for the quarter ended March 31, 1996 due primarily to
(i) a $1.4 million write-off of unamortized costs related to KRES's previous
credit facility which was replaced in January 1997, and (ii) increased costs in
the management information services and accounting departments required to
accomodate growth.
   
  Net Income (Loss) and EBITDA. For the quarter ended March 31, 1997, KRES
incurred a $1.9 million loss, which includes a $720,000 (net of 40% tax rate)
write-off of unamortized loan costs related to KRES' previous credit facility.
For the quarter ended March 31, 1996, KRES had income of $142,000. The $2.0
million change was due to the reasons cited above. EBITDA of $1.1 million for
the quarter ended March 31, 1997 decreased $2.8 million (71.8%) as compared to
$3.9 million for the quarter ended March 31, 1996.     
 
NINE MONTHS ENDED DECEMBER 31, 1996 COMPARED TO NINE MONTHS ENDED DECEMBER 31,
1995
 
  Revenue from Property and Corporate Services Division. The majority of this
division's revenue is recurring base contract fees and direct cost
reimbursement. Other revenue includes commissions from leasing
 
                                       71
<PAGE>
 
and property sales transactions net of related commissions paid to others.
Revenue of $78.4 million for the nine months ended December 31, 1996 increased
$7.4 million (10.4%) as compared to revenue of $71.0 million for the nine
months ended December 31, 1995. This increase was due to revenue from new
facilities management contracts and increased transaction revenue for client
advisory services.
 
  Revenue from the Investment Management Division. Investment management
revenue is generated by recurring base investment management fees and contract
incentive fees related to the achievement of investment yields in excess of
base amounts stipulated in various of KRES' investment management contracts.
Other components of revenue include fees associated with the acquisition and
disposition of real estate assets on behalf of clients. Revenue of $15.5
million for the nine months ended December 31, 1996 decreased $900,000 (5.5%)
as compared to revenue of $16.4 million for the nine months ended December 31,
1995. This decrease was primarily due to decrease in acquisition activity and
related fees.
 
  Costs of Property and Corporate Services Division. Costs and expenses of
this division's Fee Based Services are primarily salaries and wages incurred
in connection with the management of properties and associated with the
division's regional administrative offices. Costs of $57.2 million for the
nine months ended December 31, 1996 increased $6.0 million (11.7%) as compared
to costs of $51.2 million for the nine months ended December 31, 1995. This
increase is primarily attributable to reimbursable costs and expenses related
to new facilities management contracts. The growth of the international
operations, which expanded from three to seven offices in Asia, also
contributed to the increase in costs of this division.
 
  Costs of the Investment Management Division. Costs and expenses of this
division's Fee Based Services are primarily salaries and wages incurred in
connection with providing investment advisory and management services. Costs
of $10.0 million for the nine months ended December 31, 1996 increased $1.1
million (12.4%) as compared to costs of $8.9 million for the nine months ended
December 31, 1995. This increase is primarily due to additional acquisition
costs related to new investment fund formation and costs related to new growth
initiatives by KRES in the real estate securitization industry.
 
  Gross Operating Margin. KRES' total fee based margin declined to 28.4% from
31.2% of revenue for the nine months ended December 31, 1996 and 1995,
respectively, due primarily to higher reimbursable costs and expenses related
to new facilities management contracts, and additional acquisition costs for
new investment fund formation and new initiatives within the Investment
Management Division.
   
  Depreciation Expense. Depreciation expense is computed using the straight-
line method over estimated useful lives ranging from three to seven years on
capital assets such as computer hardware, software, office furniture and
equipment and leasehold improvements. Depreciation expense of $1.8 million for
the nine months ended December 31, 1996 increased $500,000 (38.5%) as compared
to $1.3 million for the nine months ended December 31, 1995 primarily as a
result of additional investments in hardware and software.     
 
  Corporate Expenses. Corporate expenses represent costs incurred by the
various corporate overhead departments, as well as net expenses incurred in
operating the temporary services, employee-relations consulting, risk
management, training, human resources, and management information services
departments, unallocated depreciation and amortization, gains and losses on
the sale of KRES' investments, and interest income. Expenses of $5.3 million
for the nine months ended December 31, 1996 increased $1.6 million (43.2%) as
compared to expenses of $3.7 million for the nine months ended December 31,
1995 due primarily to increased costs in the accounting and management
information services departments required to accommodate growth partially
offset by a gain on the sale of KRES' interest in two investments.
 
  Amortization expense. Amortization expense consists primarily of
amortization of the costs of management agreements, covenants not to compete
and goodwill associated with the KRES/KMS Merger and other acquisitions. The
costs associated with acquired management agreements are amortized over the
periods benefited ranging from two to ten years. Covenants not to compete are
amortized over the periods benefited ranging from five to ten years. Goodwill
resulting from the KRES/KMS Merger is being amortized over 30 years
 
                                      72
<PAGE>
 
and goodwill resulting from other acquisitions is being amortized over a range
of five to 30 years. Amortization expense of $5.9 million for the nine months
ended December 31, 1996 increased $1.0 million (20.4%) as compared to $4.9
million for the nine months ended December 31, 1995 primarily due to the
amortization of the costs of management agreements and assets acquired after
December 31, 1995.
   
  Net Income (Loss) and EBITDA. For the nine months ended December 31, 1996,
KRES incurred a $297,000 net loss. For the nine months ended December 31,
1995, KRES had net income of $1.2 million. The $1.5 million change was due to
the reasons cited above. EBITDA of $12.1 million for the nine months ended
December 31, 1996 decreased $200,000 (1.6%) as compared to $12.3 million for
the nine months ended December 31, 1995.     
 
YEAR ENDED MARCH 31, 1996 COMPARED TO YEAR ENDED MARCH 31, 1995
 
  Revenue from Property and Corporate Services Division. Revenue of $95.6
million for the year ended March 31, 1996 increased $30.4 million (46.6%) as
compared to revenue of $65.2 million for the year ended March 31, 1995. The
acquisitions of Shelard, CBS and Ross-Dove contributed $23.2 million of the
revenue increase. Other revenue contributions included (i) approximately $5.9
million in additional facilities management revenue, primarily from four new
contracts and (ii) a $2.1 million increase from two smaller acquisitions.
Managed square feet increased 14.6 million square feet from March 31, 1995 to
March 31, 1996.
 
  Revenue from Investment Management Division. Revenue of $20.7 million for
the year ended March 31, 1996 increased $4.2 million (25.2%) as compared to
revenue of $16.5 million for the year ended March 31, 1995 primarily due to
acquisition and management fees earned from newly-formed investment funds.
Additionally, the NREI acquisition in April 1995 added $1.0 million in
revenue. Assets under management increased $207 million from March 31, 1995 to
March 31, 1996.
 
  Costs of Property and Corporate Services Division. Costs of $69.6 million
for the year ended March 31, 1996 increased $21.8 million (45.6%) as compared
to $47.8 million for the year ended March 31, 1995. The acquisitions of
Shelard, CBS and Ross-Dove added expenses totaling $17.0 million. The balance
of the increase was primarily due to (i) approximately $4.1 million related to
new facilities management contracts, (ii) $1.6 million related to two smaller
acquisitions and (iii) approximately $1.5 million related to KRES' investment
in international operations. These increases were partially offset by reduced
expenses associated with reductions in overhead in certain departments and
restructuring of compensation arrangements.
 
  Costs of Investment Management Division. Costs of $10.9 million for the year
ended March 31, 1996 increased $1.7 million (18.3%) as compared to costs of
$9.2 million for the year ended March 31, 1995 primarily due to the
acquisition of NREI in April 1995.
 
  Gross Operating Margin. KRES' total fee based margin increased to 30.8% from
30.3% of revenue for the years ended March 31, 1996 and 1995, respectively,
due primarily to the acquisitions of Shelard, CBS and Ross-Dove in the
Property and Corporate Services Division, along with higher acquisition and
management fees earned on newly-formed Investment Division funds.
 
  Depreciation Expense. Depreciation expense of $1.9 million for the year
ended March 31, 1996 increased $715,000 (61.2%) as compared to $1.2 million
for the year ended March 31, 1995 primarily as a result of KRES' investment in
computer hardware and software.
 
  Corporate Expenses. Corporate expenses represent costs incurred by the
various corporate overhead departments, as well as net expenses incurred in
operating the risk management, training, human resources, and management
information services departments, unallocated depreciation and amortization,
gains and losses on the sale of KRES' investments, and interest income.
Expenses of $5.5 million for the year ended March 31, 1996 increased $100,000
(1.9%) as compared to expenses of $5.4 million for the year ended March 31,
1995 due primarily to increased infrastructure costs in the accounting, human
resources, and management information
 
                                      73
<PAGE>
 
services departments required to accommodate the acquisitions of Shelard, CBS,
and Ross Dove in the Property and Corporate Services Division. This increase
was mostly offset by $800,000 in merger costs incurred while bringing the
company private in the year ended March 31, 1995.
 
  Amortization Expense. Amortization expense of $6.9 million for the year
ended March 31, 1996 increased $4.0 million (136.4%) as compared to $2.9
million for the year ended March 31, 1995 as the result of amortization of
goodwill and management contracts related to the Ross-Dove and CBS
acquisitions, which were completed in March 1995, the fiscal 1996
acquisitions, including Shelard, and the amortization of goodwill related to
the Merger.
   
  Net Income and EBITDA. For the year ended March 31, 1996 as compared to the
year ended March 31, 1995, net income increased $655,000 (101.6%) from
$645,000 to $1.3 million and EBITDA increased $9.6 million (145.5%) from $6.6
million to $16.2 million primarily due to increased revenues from KRES'
acquisitions and growth of existing operations.     
 
LIQUIDITY AND CAPITAL RESOURCES
 
  For the quarter ended March 31, 1997, the operations of KRES generated cash
of $745,000. KRES used $1.3 million for investing activities, including
$622,000 for the purchase of furniture, fixtures and equipment and $477,000
for investments in and advances to its unconsolidated subsidiaries. KRES
received an equity infusion from certain existing shareholders of $25 million,
had net repayments on debt of $22.2 million, paid $2.5 million in financing
fees and distributed $680,000 in minority partners' earnings, which, among
other uses, resulted in a net use of cash for financing activities of
$512,000. The total net decrease in cash and cash equivalents for the quarter
ended March 31, 1997 was $1.1 million.
 
  For the nine months ended December 31, 1996, the net cash used in KRES'
operating activities totalled $4.4 million. KRES used a net of $3.1 million
for investing activities, including the combined expenditure of $7.5 million
for the acquisition of management agreements and businesses ($2.5 million),
the purchase of furniture, fixtures and equipment ($2.2 million) and
investments in and advances to its unconsolidated subsidiaries ($2.8 million).
Offsetting this was $4.4 million of net proceeds from the sale of KRES'
investment in two limited liability companies. Financing activities provided
cash of $3.0 million, which included $8.8 million in net borrowings on the
credit facility, $1.5 million in payments in connection with current and prior
years' acquisitions, and $4.2 million in distributions for minority partners'
share of earnings. The total net decrease in cash and cash equivalents for the
nine months ended December 31, 1996 was $4.6 million.
 
  KMS has a credit facility agented by Bankers' Trust Company, which as of
March 31, 1997, provided for a $70 million revolving facility ($45 million for
acquisitions and $25 million for working capital) and a $25 million term loan.
The credit agreement matures on September 30, 2001 and periodic principal
reductions are required beginning March 31, 1998. All amounts outstanding
under the credit facility bear interest at a customary base rate or Eurodollar
rate plus a margin based upon KMS' leverage ratio (the ratio of total debt to
earnings before interest, taxes, depreciation and amortization). The margins
range from 0% to 0.75% in the case of the base rate and from 0.625% to 1.75%
in the case of the Eurodollar rate. The credit facility is guaranteed by KRES
and KMS' wholly-owned subsidiaries and is secured by a pledge of stock of KMS
and each of its wholly-owned subsidiaries. As of March 31, 1997, $28.5 million
was outstanding under the credit facility, consisting of $25.0 million on the
term loan and $3.5 million on the working capital sublimit. As of May 31,
1997, $45.2 million was outstanding under the credit facility, consisting of
$25.0 million on the term loan, $16.3 million on the working capital sublimit,
and $3.9 million on the acquisition sublimit.
 
  The credit facility contains certain customary affirmative and negative
covenants, including but not limited to covenants regarding KMS' leverage
(maximum debt is three times EBITDA), net worth (minimum net worth as of March
31, 1997 was $46.7 million) and interest coverage (minimum EBITDA is four
times interest), the prohibition of any dividend payments to KRES other than
amounts permitted to cover certain administrative expenses ($50,000 annually)
and to repurchase, pursuant to the terms of certain subscription agreements,
KRES common stock from management (aggregate limit of $750,000), as well as
limitations on other indebtedness,
 
                                      74
<PAGE>
 
liens, investments, and mergers and acquisitions. There are no premiums or
prepayment penalties under the KMS credit facility.
   
  For the 12 months ended March 31, 1996, KRES' operations generated cash of
$9.5 million. Cash provided by operating activities resulted primarily from net
income and increases in accounts payable and accrued liabilities offset by an
increase in accounts receivable. KRES used $13.9 million in investing
activities, which included $8.4 million for the acquisition of management
agreements and businesses and $2.2 million for the purchase of furniture,
fixtures and equipment. Financing activities provided cash of $11.2 million,
which included $23.1 million in net borrowings on the credit facility, less
$10.8 million in payments in connection with current and prior years'
acquisitions. The resulting net increase in cash and cash equivalents for the
12 months ended March 31, 1996 was $6.8 million.     
 
  The Merger proposed herein represents a violation of certain covenants of the
credit facility, and consummation of the Merger would require repayment in full
of the amounts outstanding under the credit facility. CBC has made arrangements
through its senior secured credit facility to pay off all amounts outstanding
under the credit facility.
 
KRES' BUSINESS
 
 Overview
 
  KRES provides real estate and real estate-related services through two
principal operating divisions: Property and Corporate Services and Investment
Management. The Property and Corporate Services Division provides (i) property
management services and (ii) corporate and facilities management services. The
Investment Management Division provides (i) real estate investment fund and
portfolio management, (ii) acquisition, disposition, financing and valuation
services related to commercial properties and (iii) real estate market and
securities research.
 
  KRES' primary business objective has been to pursue increased revenue, market
share and profitability through (i) providing and developing new services for
existing and prospective institutional and corporate clients and property
tenants and their employees operating properties managed by KRES, (ii)
capitalizing on the trend by large corporations to reduce operating costs by
outsourcing their non-core activities and (iii) taking advantage of recovering
and emerging real estate markets through acquisitions and joint ventures to
expand its geographic market into markets that it does not currently service.
 
 Property & Corporate Services Division
 
  The Property and Corporate Services Division operates through 10 regional
offices and 255 field offices in the United States and Asia. KRES performs
property and facilities management and leasing services for an approximately
146 million square foot portfolio of office, industrial, retail, multi-family
and corporate space.
 
  Property Management. Property management services include maintenance,
marketing and leasing services for investor-owned, but not typically investor-
occupied, property. KRES currently provides property management services to
more than 325 clients. A typical property management agreement requires KRES to
provide the following services: (i) billing and collection of rent payments and
other charges, (ii) payment of expenses for property operations, (iii)
negotiation of new leases, lease renewals and tenant expansions,
(iv) development and implementation of marketing plans and promotions for each
property using market data, (v) taking actions necessary for the proper
management of the properties (including physical inspections, supervision of
maintenance activities, responding to tenant requests and arranging for
improvements and repairs), (vi) negotiation of service and labor contracts to
maintain a property, (vii) maintenance of records of funds received and
disbursed in connection with a property, (vii) preparation of accounting and
financial reports and income and cash flow budgets, (viii) coordination of
management activities and (ix) procurement of legal services to assist in
collection of rent or eviction of tenants.
 
 
                                       75
<PAGE>
 
  Under a typical property management agreement, KRES will be entitled to
receive management fees and lease commissions. The management fee in most
cases is a specified percentage of the monthly gross rental income generated
and collected from tenants occupying the property under management, and as a
result, will increase and decrease as building rents and occupancies increase
and decrease. Many of these property management agreements also include a
stated minimum management fee. KRES also may be entitled to reimbursement for
costs (such as costs of wages of on-site employees, field office rent,
supplies and utilities) incurred that are directly attributable to management
of the property. Under certain property management agreements, KRES may also
be entitled to construction management fees.
 
  Lease commissions, which are calculated as a percentage of the minimum rent
payable under the terms of the lease, are generally earned by KRES at the
commencement of a lease and are not contingent upon the tenant fulfilling the
terms of the lease. In cases where a real estate broker is not involved, lease
commissions earned by KRES for a new lease typically range between 2% and 6%
of minimum rent payable under the lease. For the renewal of an existing lease,
such fees are generally 50% of a new lease commission. In cases where a third-
party real estate broker is involved, KRES typically must share 50% of its
commission with the broker.
 
  A property management agreement typically provides that the agreement
remains in effect for an indefinite period but enables the property owner to
terminate the agreement upon 30 days' prior written notice, which KRES
believes to be a customary industry termination provision. KRES historically
has been reasonably successful in retaining property management agreements,
but has experienced the loss of such agreements in certain instances when a
property has been sold or when a property owner decides to change property
managers or to assume direct responsibility for managing the property.
 
  Corporate Services and Facilities Management. The Corporate Services Group
specializes in the administration, management and maintenance of properties
that are owned and occupied by large corporations and institutions, such as
corporate headquarters, regional offices, administrative offices and
manufacturing and distribution facilities, as well as tenant representation,
capital asset disposition, strategic real estate consulting and other
ancillary services for corporate clients. KRES' portfolio of corporate and
facilities assignments has facilities management, including reducing building
and operations costs, maintaining and enhancing the value of each facility and
providing managerial and technical support. Services that KRES provides
include tenant representation, acquisition and disposition strategies,
strategic real estate consulting, operations and maintenance, lease
administration, contract management, operational surveys and audits, technical
and administrative support and ancillary services. KRES focuses on developing
programs for its corporate clients in total quality management, operating cost
benchmarking, proprietary lease administration and building management
software and the establishment of vendor performance standards.
 
  Under a typical facilities management agreement, KRES is entitled to receive
management fees and reimbursement for its costs (such as costs of wages of on-
site employees, field office rent, supplies and utilities) incurred that are
directly attributable to management of the facility. In most instances, office
space and furniture for the on-site office are provided by the client. Under
certain facilities management agreements, KRES may also be entitled to an
additional incentive fee which is paid if KRES meets certain performance
criteria established in advance between the client and KRES. The management
fee in most cases is based upon a fixed annual amount per square foot of the
facility managed.
 
  A typical facilities management agreement is written for a stated term of
one or more years and may contain provisions for extensions of the agreement.
Agreements typically include a provision for cancellation by either party upon
the giving of notice within a specified short time frame.
 
  In addition to the services described above, through its acquisition of
Koll-Dove, KRES conducts auctions for capital assets, commercial real estate,
financial instruments, excess or obsolete inventory and other assets. Clients
seeking to dispose of excess capital assets include defense contractors,
personal computer manufacturers and distributors, printed circuit board
companies and semiconductor fabrication firms. Clients utilizing Koll-Dove to
auction commercial and financial assets real estate include banks, commercial
and asset-based lenders,
 
                                      76
<PAGE>
 
restructuring businesses and insurance companies. Through its 30% interest in
Koll Telecommunications, KRES also provides site location and acquisition,
entitlement and zoning, leasing and construction management services for
telecommunication cell sites nationwide. See "--Acquisitions".
 
  In November 1994, KRES expanded its operations to Asia to capitalize on the
region's growth potential and demand for U.S. real estate expertise and
systems. In June 1995, KRES received a license to do business in China,
enabling KRES to provide services in this large and emerging market. Under the
name "Koll Asia Pacific," KRES has hired and partnered with local
professionals to gain the necessary cultural and local business knowledge to
deliver services in Asia that are similar to those KRES delivers in the United
States. Koll Asia Pacific has offices in Singapore, Shanghai, Tokyo, Hong
Kong, Beijing, Kuala Lumpur, Bangkok, Manila and Jakarta, where KRES'
operational headquarters is located. KRES' technical support services are
located in Singapore. To date KRES' Asian operations have not been profitable.
 
 Investment Management Division
 
  The Investment Management Division provides a variety of asset and portfolio
management services to the pension fund and institutional real estate
investment community including (i) real estate investment fund and portfolio
management, (ii) acquisition, disposition, financing and valuation services
related to commercial properties and (iii) real estate market and securities
research. As of March 31, 1997, the Division managed asset portfolios,
consisting primarily of commercial real estate investments, which had an
aggregate cost basis of approximately $2 billion, over half of which had been
raised through a joint venture with The Bren Company, a New York-based real
estate investment management company. The Investment Management Division has
over 80 clients, such as pension funds, banks, insurance companies, high net-
worth individuals, partnerships and international investors. KRES is a sponsor
and manager of 19 separate accounts and seven commingled funds which are
invested principally in commercial properties and mortgage assets.
 
  KRES provides the following additional services for its real estate
investment clients: strategic planning, investment analysis, risk management,
fiduciary oversight, financial forecasts, due diligence, equity and mortgage
asset management, and mortgage banking. Certain subsidiaries of KRES are
Registered Investment Advisors under the Investment Advisors Act of 1940.
 
  Direct Investment Management. The Investment Management Division raises
funds from new and existing clients, acquires direct equity and mortgage
positions in portfolios of real estate and securitized real estate
investments, actively manages these investments to maximize their value,
including ongoing strategic assessment of properties, and evaluates and
disposes of assets and investments to generate the highest portfolio return
consistent with client objectives. During the last two years, KRES has raised
in excess of $935 million, has completed acquisitions of real estate assets
valued in excess of $1 billion and has completed dispositions of real estate
assets valued at approximately $580 million.
 
  KRES acquires portfolios of direct equity and mortgage positions in
investment-grade real estate and performing and non-performing real estate
mortgages through the acquisition of portfolios and single assets that offer
growth potential in cash flow and investment value. Acquisition services are
provided by professionals who focus on finding and acquiring properties that
satisfy clients' requirements. KRES provides acquisition services for real
estate equities and mortgages involving industrial, retail, office, multi-
family, hotels and resorts and other types of property. These services include
pricing, transaction structuring, due diligence and market research.
 
  Once assets are acquired, KRES assists each client in developing
individually tailored strategies for increasing the value of a mortgage or
equity asset. The plan is then implemented after conducting an analysis of the
relative market position of each asset, including its location and leasing
status, existing physical condition, legal and environmental issues and
current market conditions. KRES manages each asset from property management
services to ongoing forecasting and valuation. In addition, KRES services the
mortgages it acquires. An investment management team is accountable for
maximizing the performance of and executing the investment strategy for each
asset to which it is assigned. KRES also has a team of disposition
professionals
 
                                      77
<PAGE>
 
who work closely with clients selling properties. The disposition teams
provide services which include valuation, marketing strategy, marketing
material production, brokerage services, broker management, sale negotiations,
financial structuring and due diligence review.
 
  Securitized Investment Management. KRES' securitized investment management
activities involve management of clients' investments in real estate
securities, principally publicly-traded REITs. Through proprietary research
models developed by NREI, including REIT-Score, KRES manages portfolios of
real estate securities for individuals and institutions that typically desire
greater liquidity than is available through direct real estate investments.
KRES believes that its securitized investment management is positioned for
solid growth due to (i) KRES' extensive real estate research activities and
(ii) the trend of institutions and individuals to allocate greater assets to
securitized real estate investments. In response to this trend, in April 1996
KRES formed a venture with Alliance Capital Management L.P. ("Alliance"), a
publicly-traded limited partnership whose largest unit-holder is The Equitable
Companies Incorporated and a leading international investment advisor with
over $180 billion in assets under management, to establish REIT mutual funds
and offer REIT portfolio management. KRES is responsible for the analysis of
the properties owned by the REITs in which the venture is investing as well as
the markets in which the REITs' properties are located, and Alliance is
responsible for the securities and financial analysis, portfolio construction
and investment advisory contracts.
 
  Market Research. Market research is supplied by KRES through NREI. NREI's
research focuses on assisting clients with analysis and interpretation of
market data in order to provide them with a competitive edge in the rapidly
changing real estate marketplace. NREI's publications and products are sold to
more than 3,000 customers, including many of the largest property managers,
portfolio managers, insurance companies and pension funds. NREI's real estate
market trend publications and related print and disk products provide real
estate price and rent data spanning 64 major U.S. markets. This research is
based upon two data bases consisting of (i) numerous real estate transactions
and (ii) quarterly information tracking the operating performance of over
2,500 commercial properties.
 
  Environmental Venture. In February 1996 KRES entered into a venture with
ENSR, an environmental remediation firm, to assist the private sector in
remediating and increasing the value of contaminated properties. This venture
offers owners of impaired properties the skills and capital necessary to
remediate and dispose of such properties. ENSR provides remediation services
and capital in connection with such remediation and KRES provide marketing,
property management and disposition services. This venture is structured to
isolate KRES from any environmental liability.
 
 Acquisitions
 
  KRES' growth strategy has focused on the acquisition of regional property
management companies in strategically-targeted markets, investment management
companies and other complementary service providers. Since April 1991, KRES
has completed more than 20 acquisitions for an aggregate purchase price in
excess of $45 million.
 
 Employees and Employee Education
 
  As of March 31, 1997, KRES had approximately 2,600 employees. KRES believes
its relationships with its employees are good.
 
  KRES' training program, known as Koll College, offers KRES' employees and
its clients training programs in the real estate industry. Since its
introduction in 1990, Koll College has become a diversified training and
development institution. Koll College has evolved into a revenue-generating
training organization for industry members and corporations.
 
  Through Koll College, KRES offers more than 50 courses which emphasize
management and professional skills to improve productivity and services
provided to clients and customers. The curriculum is structured to
 
                                      78

address a variety of career levels and lines of business. Course subject
matter ranges from orientation information for new employees to executive
programs for senior management. Taught by a full-time staff of instructors who
are aided by KRES' internal "subject matter experts" in specialized fields,
the classes relate directly to the latest industry knowledge and technology.
As an example of KRES' involvement in the industry, Koll College was asked to
partner with the International Facility Management Association to provide
training programs to its members nationwide.
 
 KRES Facilities
 
  KRES' executive offices are located in Newport Beach, California and consist
of 102,339 square feet of office space leased from The Koll Company and one of
its affiliates. These offices are under four leases: 53,445 square feet which
is on a monthly basis, 9,381 and 20,481 square feet which expire February
2002, and 19,032 square feet which expires June 2000. KRES also has 10
regional offices and 255 field management offices. Certain regional offices
are leased from clients of KRES on terms which KRES believes reflect the fair
market value of comparable office space. The field management offices are
typically located in managed properties and are often provided by the property
owners without charge to KRES.
 
 Legal Proceedings
 
  KRES is subject to claims and suits in the ordinary course of business.
There are no legal proceedings pending or, to the knowledge of management,
threatened against KRES that could, if determined adversely, have a material
adverse effect on KRES' financial condition, results of operations or cash
flows.

              UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
                                  (UNAUDITED)
 
  The following unaudited pro forma balance sheet as of March 31, 1997 and
statements of operations for the three months ended March 31, 1997 and for the
year ended December 31, 1996 ("the pro forma financial statements") give
effect to (i) the Merger as if it had occurred as of January 1, 1996 in the
pro forma combined statements of operations and as of March 31, 1997 in the
pro forma combined balance sheet and (ii) the acquisition, in the pro forma
combined statements of operations for the year ended December 31, 1996, of
L. J. Melody by CBC as if this acquisition had occurred as of January 1, 1996.
See "DESCRIPTION OF CAPITAL STOCK and THE MERGER."
 
  The pro forma adjustments are based upon currently available information and
upon certain assumptions that management believes are reasonable. The Merger
and the acquisition of L. J. Melody have been accounted for by CBC as a
purchase. The adjustments included in the pro forma financial statements
represent the effects of CBC's preliminary determination and allocation of the
purchase price to the fair value of the assets and liabilities acquired, based
upon currently available information. There can be no assurance that the
actual effects will not differ significantly from the pro forma adjustments
reflect in the pro forma financial statements.
 
  The pro forma financial statements are not necessarily indicative of either
future results of operations or results that might have been achieved if the
transactions had been consummated as of the dates indicated. The pro forma
financial statements should be read in conjunction with the historical
consolidated financial statements and footnotes of CBC, KRES and L. J. Melody
included herein.

(a) Represents the write-off of amounts related to certain KRES deferred costs
    that have been reallocated to the purchase price of assets acquired by
    CBC. These costs consisted primarily of costs to organize and structure
    investment funds in which KRES holds general partnership interests ($6.1
    million), investments and advances ($1.7 million), organization costs
    ($1.2 million) and miscellaneous other assets.
 
(b) Represents the fair value of CBC Common Stock, options and warrants
    expected to be issued in connection with the Merger and the elimination of

<TABLE>
      <S>                                                            <C>
      Severance for KRES employees expected to be terminated........ $2,011,000

      Integration costs.............................................    492,000
      Transaction fees and related costs............................  3,975,000
</TABLE>
 
  Integration costs consist primarily of third party costs for certain
  software modifications required to be made to the KRES computer systems in
  order to make them compatible with operational requirements of the combined
  entity. Transaction fees and related costs consist primarily of investment
  banker fees, the cost of financial due diligence, legal and accounting
  fees.
 
(e) Represents the component of the purchase price allocated to the estimated
    current fair value of incentive fees KRES is entitled to receive upon the
    liquidation of real estate investment funds KRES manages.
 
(f) Represents the adjustment to reflect KRES' management contracts at their
    estimated current fair value.
 
(g) Represents the adjustment to reflect KRES' investments at their estimated
    current fair value.
 
(h) Represents adjustments to reflect the tax effect of the pro forma
    adjustments including adjustments to goodwill for deferred taxes resulting
    from KRES related items and adjustments to retained earnings for deferred
    taxes resulting from CBC related items.
 
(i) CBC expects to incur additional costs resulting from the merger associated
    with severance for CBC employees expected to be terminated and CBC's
    system integration costs. The pro forma combined balance sheet does not
    reflect an adjustment related to such costs which are currently estimated
    at $6.5 million.

(a) Represents the gross up of commissions paid by KRES to its brokers as
    revenues and commission expense to conform to CB's reporting format.
 
(b) Represents an adjustment to reflect KRES's revenues and operating costs
    net of onsite reimbursable costs incurred and charged to tenants, in order
    to conform to CB's reporting format.
 
(c) Represents reversal of KRES's historical amortization expense related to
    its goodwill, amortization of certain deferred costs and other
    intangibles.
 
(d) Represents amortization expense for management agreements assuming a
    useful life of 10 years for facilities management and 4 years for property
    management contracts. Property management contracts generally have 30-day
    renewable terms and facilities contracts have an average remaining term of
    7 years, including automatic renewal options. Most contracts also have
    additional renewal option periods.
 
  The 4 year life for property management contracts is based on KRES's
  historical experience of 25 percent average annual runoff rate on such
  contracts. An amortization period of 10 years was selected for facilities
  contracts as KRES has a history of runoff on such contracts of
  approximately 10 percent per annum. The facilities management contracts are
  based on long standing relationships with clients and have historically
  proven to maintain a relatively consistent runoff rate and most of them
  have been consistently renewed at their respective renewal dates. CBC
  expects to continue to have a similar experience with these contracts.
 
(e) Represents amortization expense on KRES's investments to amortize the
    difference between the purchase price allocated to these investments and
    their underlying net book value.
 
(f) Represents amortization expense for total goodwill resulting from the
    transaction using a 30 year estimated useful life.
 
(g) Represents reversal of KRES's tax benefit associated with its historical
    amortization expense.
 
(h) Represents the tax effect of the pro forma adjustments.
 
(i) Represents amortization expense for covenants not to compete over the
    average remaining terms of 3 years.
 
(j) Reflects the effect of the pro forma number of weighted average common
    stock and common stock equivalent shares giving effect to the CBC Common
    and CBC Common equivalent shares to be issued in connection with the
    Merger. The weighted average number of shares are calculated as follows:

   historical experience of 25 percent average annual runoff rate on such
   contracts. An amortization period of 10 years was selected for facilities
   contracts as KRES has a history of runoff on such contracts of
   approximately 10 percent per annum. The facilities management contracts are
   based on long standing relationships with clients and have historically
   proven to maintain a relatively consistent runoff rate and most of them
   have been consistently renewed at their respective renewal dates. CBC
   expects to continue to have a similar experience with these contracts.
 
(j) Represents amortization expense on KRES's investments to amortize the
    difference between the purchase price allocated to these investments and
    their underlying net book value.
 
(k) Represents amortization expense for total goodwill resulting from the
    transaction using a 30 year estimated useful life.
 
(l) Represents amortization expense for covenants not to compete over the
    average remaining terms of 3 years.
 
(m) Represents the tax effect of the pro forma adjustments.
 
(n) Represents reversal of KRES's tax benefit associated with the amortization
    of its historical amortization expense.
 
(o) Reflects the effect of the pro forma number of weighted average common
    stock and common stock equivalent shares giving effect to the CBC Common
    and the CBC Common equivalent shares to be issued in connection with the
    Merger.

                       DESCRIPTION OF CBC CAPITAL STOCK
 
  The following summary is a description of certain provisions of CBC's
Certificate and Bylaws that will be in effect upon consummation of the Merger.
Such summary does not purport to be complete, and is qualified in its entirety
by all of the provisions of the CBC Certificate and Bylaws. The authorized
capital stock of CBC consists of 100,000,000 shares of Common Stock, $.01 par
value ("CBC Common"), and 8,000,000 shares of preferred stock, $.01 par value
("CBC Preferred").
 
CBC COMMON STOCK
   
  As of July 7, 1997, there were 13,460,436 shares of CBC Common outstanding
held by approximately 972 stockholders of record. The holders of CBC Common
are entitled to one vote for each share held of record on all matters
submitted to a vote of the stockholders, including the election of directors,
and do not have cumulative voting rights. Accordingly, the holders of shares
of CBC Common and CBC Preferred with a majority of the votes entitled to vote
in any election of directors can elect all of the directors standing for
election, if they so choose. Subject to preferences that may be applicable to
any then outstanding CBC Preferred, holders of CBC Common are entitled to
receive ratably such dividends, if any, as may be declared by the Board of
Directors out of funds legally available therefor. Upon a liquidation,
dissolution or winding up of CBC, subject to the payment of any amounts which
holders of CBC Preferred are entitled to receive in preference to holders of
CBC Common, to the extent any assets of CBC remain available for distribution
to stockholders, the holders of CBC Common and CBC Preferred are entitled to
receive $10.00 per share, reduced by any prior payments to such holder in
connection with any liquidation, dissolution or winding up of CBC (not
including accrued and unpaid dividends and accrued interest thereon). The
holders of CBC Common are entitled to share in the remaining assets (after the
aforementioned $10.00 per share distribution) of CBC legally available for
distribution, with the holders of CBC Preferred receiving an amount of such
remaining assets per share equal to sixty percent (60%) of the per share
amount distributed with respect to the CBC Common. Holders of CBC Common have
no preemptive or conversion rights or other subscription rights and there are
no redemption or sinking funds provisions applicable to the CBC Common. All
outstanding shares of CBC Common are, and the shares of CBC Common to be
outstanding upon consummation of the Merger will be, fully paid and
nonassessable.     
 
CBC PREFERRED STOCK
 
  The CBC Preferred consists of a single class of 8,000,000 shares, of which
three series are outstanding: (a) 1,000,000 shares of Series A-l Preferred
Stock ("CBC A-1 Preferred"), (b) 2,000,000 shares of Series A-2 Preferred
Stock ("CBC A-2 Preferred") and (c) 1,000,000 shares of Series A-3 Preferred
Stock ("CBC A-3 Preferred Stock" and, collectively with the CBC A-1 Preferred
and CBC A-2 Preferred, "Preferred Stock").
 
  Holders of CBC Preferred are entitled to dividends ("Preference Dividend")
at the rate of $0.25 per fiscal quarter on each share of Preferred Stock,
payable out of funds legally available therefor. The accrual of such dividend
is retroactive to October 1, 1996. Until CBC has completed its acquisition
program, it does not intend to pay the dividend on the Preferred Stock. As a
consequence, such dividend will accumulate and bear interest which will be
paid on a current basis, and CBC will be prohibited from voluntarily pre-
paying long-term debt until such accumulated dividend and interest have been
paid in full. If CBC refinances its existing bank indebtedness it will be
required to pay all accrued but unpaid Preference Dividends. CBC is in the
process of exploring its options with respect to a refinancing of its debt.
 
  In the event the Preference Dividend is not declared and paid within one
year after the last day of the quarter to which it relates, it will bear
compound annual interest at a fixed rate of 8% annually, with respect to the
CBC A-1 and A-3 Preferred and, with respect to the CBC A-2 Preferred, at
either (i) a fixed rate of 8% annually or (ii) an annual rate equal to the
six-month rate offered to The Sumitomo Bank, Limited in the London interbank
market, for amounts comparable to the amount of any unpaid dividend, plus 2
1/2%. The holders of the CBC A-2 Preferred have elected the variable rate
option. As of July 16, 1997, such six-month rate offered by the Sumitomo
 
                                      88
<PAGE>
 
Bank, Limited was 5.9375%. Until all accrued and unpaid Preference Dividends
are paid, no shares of CBC Common will be redeemed by CBC (other than shares
issued pursuant to stock option, stock purchase or similar plans), and no
dividends will be paid on any shares of CBC Preferred (other than the CBC A-1,
A-2 and A-3 Preferred) or CBC Common.
 
  The Preference Dividend will not be paid, and no interest will accrue or be
paid thereon, if applicable law restricts or prohibits the declaration or
payment of the Preference Dividend. The Preference Dividend is also not be
required to be declared or paid to the extent it would violate any contractual
restrictions in a credit agreement of CBC. CBC has agreed that it will not
enter into any contractual prohibition with respect to the accumulation of
dividends or the accrual and payment of interest on any unpaid dividends with
respect to the CBC Preferred.
 
  In addition to the Preference Dividend and any interest payable thereon,
each share of CBC Preferred is entitled to receive dividends in the amount of
sixty percent (60%) of the amount received by each share of CBC Common.
 
  Upon any liquidation, dissolution or winding up of CBC, holders of CBC
Preferred and CBC Common are entitled to share in the remaining assets of CBC
after payment of liabilities and any accrued and unpaid Preference Dividend,
including any interest thereon, subject to prior distribution rights of other
preferred stock, if any, then outstanding, as follows: (i) each holder of CBC
Preferred and CBC Common is entitled to receive an amount, reduced by any
prior payments to such holder pursuant to such liquidation, dissolution or
winding up of CBC, other than the Preference Dividend and any interest
thereon, equal to $10.00 per share and (ii) each holder of CBC Preferred is
entitled to share ratably in all remaining assets of CBC to the extent of
sixty percent (60%) of the distribution, with respect to each share of CBC
Common, in excess of $10.00.
 
  The holders of shares of CBC A-2 Preferred have one (1) vote per share of
CBC A-2 Preferred. The holders of shares of CBC A-1 Preferred have two (2)
votes per share of CBC A-1 Preferred on all matters submitted to a vote of the
stockholders of CBC and, except as provided by law, vote together with the
holders of shares of CBC A-2 Preferred and the holders of CBC Common as one
class on all matters submitted to a vote of stockholders of CBC. The holders
of CBC A-3 Preferred are not entitled to vote on any matters, except as
required by law.
 
  The CBC Preferred is convertible into shares of CBC Common at the option of
the holder thereof at a ratio ranging from .60 to .78 shares of CBC Common for
each share of CBC Preferred, depending on the Market Price (as defined below)
of the CBC Common at the time of conversion as follows:

  The term "Market Price" means the average closing price for a share of
Common Stock as reported by The Wall Street Journal (West Coast Edition) for
20 consecutive trading days immediately preceding the date as of which
conversion occurs.
 
  The CBC Board has the authority, subject to certain rights of the CBC A-1,
A-2 and A-3 Preferred and without further action by the stockholders, to issue
the authorized shares of preferred stock not included in such
 
                                      89
<PAGE>
 
series from time to time in one or more series and to fix the number of
shares, designations, preferences, powers, and relative, participating,
optional or other special rights and qualifications or restrictions thereof.
In addition, upon conversion of any of the CBC Preferred, the shares converted
will be available for issuance in one or more series from time to time. The
preferences, powers, rights and restrictions of different series of preferred
stock may differ with respect to dividend rates, amounts payable on
liquidation, voting rights, conversion rights, redemption provisions, sinking
fund provisions and purchase funds and other matters. The issuance of
additional CBC Preferred could decrease the amount of earnings and assets
available for distribution to holders of CBC Common or adversely affect the
rights and powers, including voting rights, of the holders of CBC Common, and
may have the effect of delaying, deferring or preventing a change in control
of CBC. CBC has no present plans to issue any shares of CBC Preferred.
 
CBC WARRANTS
 
  Each Warrant issuable pursuant to the Merger will be exercisable into a
share of CBC Common at an exercise price of $30.00 per share of CBC Common. In
addition, each Warrant will have a term of 7 years from the Closing Date, will
become exercisable on the third anniversary of the Closing Date and will be
subject to the terms and conditions of a Warrant Agreement to be entered into
by and among CBC, Acquisition Corporation and the KRES Shareholders as of the
Closing Date.
 
  The Exercise Price of the Warrants is subject to adjustment as appropriate
in certain circumstances, including if CBC, after the issuance of such
Warrants (i) pays a dividend or makes a distribution on CBC Common in shares
of CBC Common or other shares of its capital stock; (ii) subdivides its
outstanding shares of CBC Common into a greater number of shares; (iii)
combines its outstanding shares of CBC Common into a smaller number of shares;
(iv) issues by reclassification of CBC Common any shares of its capital stock;
(v) distributes rights, options or warrants to all holders of its CBC Common
entitling them to purchase shares of CBC Common at a price per share less than
the current market price per share on that record date; (vii) distributes to
all holders of CBC Common any assets (excluding cash) or debt securities or
any rights or warrants to purchase debt securities, assets or other
securities; (viii) issues shares of CBC Common for a consideration per share
less than the current market price per share on the date CBC fixes the
offering price of such additional shares; or (ix) issues any securities
convertible into or exchangeable or exercisable for CBC Common (other than
securities issued in transactions described in clauses (vi) and (vii) above)
for a consideration per share of CBC Common less than the current market price
per share on the date of issuance of such securities.
 
  No adjustment is made to the Exercise Price for certain issuances of CBC
Common at prices below the current market price, including CBC Common issued
(i) upon the exercise of Warrants or certain rights or the conversion or
exchange of other securities; (ii) to CBC's employees under employee benefit
plans; (iii) in proportionate amount to shareholders of any person which
merges into CBC; (iv) in a firmly underwritten public offering; (v) in a
private placement to, or through certain placement agents or (vi) as a
dividend on any preferred stock in lieu of cash dividends. No adjustment is
made to the Exercise Price for certain issuances of securities convertible
into CBC Common including in the circumstances described in clauses (iii),
(iv) and (v), above, securities outstanding prior to the date of issuance of
the Warrants and certain issuances of convertibles securities in connection
with the incurrence of debt.
 
  The "current market price" per share of CBC Common (for purposes of
adjustments to the Exercise Price of the Warrants) on any date is the average
of the Quoted Prices of the CBC Common for 30 consecutive trading days
commencing 45 trading days before the date in question. The "Quoted Price" of
the CBC Common is the last reported sales price of the CBC Common as reported
by the Nasdaq National Market, or if the CBC Common is listed on a securities
exchange, the last reported sales price of the CBC Common on such exchange
which shall be for consolidated trading if applicable to such exchange, or if
neither so reported or listed, the last reported bid price of the CBC Common.
In the absence of one or more such quotations, the Board of Directors of the
Company shall determine the current market price on the basis of such
quotations or other valuation information as it in good faith considers
appropriate.
 
                                      90
<PAGE>
 
  If CBC consolidates or merges with or into, or sells, transfers or leases
all or substantially all of its assets to, any person, upon consummation of
such transaction the Warrants shall automatically become exercisable for the
kind and amount of securities, cash or other assets which the holder of a
Warrant would have owned immediately after the consolidation, merger, sale,
transfer or lease if the holder had exercised the Warrant immediately before
the effective date of the transaction.
 
  Upon each adjustment of the Exercise Price, the number of shares of CBC
Common into which each Warrant outstanding prior to the making of the
adjustment in the Exercise Price is exercisable is adjusted by multiplying the
number of shares such Warrant was exercisable into prior to the adjustment by
a fraction equal to the Exercise Price prior to such adjustment divided by the
Exercise Price following such adjustment.
 
  Following the Effective Time and until the Warrants become exercisable, if
any New Option expires or is terminated without being exercised, all Warrants
issued in respect of the KRES Options for which such New Option was exchanged
shall be forfeited by the holder thereof. At such time as the Warrants become
exercisable, all Warrants forfeited pursuant to the immediately preceding
sentence shall be reallocated among the Reallocation Holders pro rata based on
the aggregate number of shares of the CBC Common issued and shares of CBC
Common underlying New Options issued to each Reallocation Holder pursuant to
the Merger Agreement divided by the total number of shares of CBC Common
issued and shares of CBC Common underlying New Options issued to all
Reallocation Holders pursuant to the Merger Agreement. See "The Merger-
Adjustments to Merger Consideration."
 
REGISTRATION RIGHTS
 
  Pursuant to a registration rights agreement between CBC and the holders of
the Preferred Stock (the "Preferred Stock Registration Rights Agreement"),
until expiration of the Rule 144 Period (as defined below), if CBC proposes to
register any of its securities, it will use its best efforts to include in
such registration CBC Common acquired by the holders of CBC Preferred upon
conversion of the CBC Preferred. The registration rights granted to the
holders of Preferred Stock do not apply to certain transactions, including
registrations relating solely to employee benefit plans, a corporate
reorganization, reclassification, merger, consolidation or acquisition or a
registration that does not permit secondary sales. The "Rule 144 Period" means
the period beginning and continuing until the CBC Common acquired on
conversion of the Preferred Stock is no longer subject to the volume
limitation provisions of Rule 144 of the Securities Act, either pursuant to
the provisions of the Registration Rights Agreement or by operation of law.
 
  In connection with the Merger, on May 14, 1997 CBC entered into a
registration rights agreement (the "KRES Registration Rights Agreement") with
FS Equity Partners III, L.P.; FS Equity Partners International, L.P.
("collectively, FS"); AP KMS Partners, L.P.; AP KMS II, LLC (collectively,
"Apollo"); Raymond Wirta; Koll Holding Company and William Rothe (collectively
with FS and Apollo, the "Principal KRES Shareholders") with respect to shares
of CBC Common issued to them in connection with the Merger or upon the
exercise of warrants issued to them in connection with the Merger. Pursuant to
this agreement, if during CBC's 1998, 1999 or 2000-2002 fiscal years such
Principal KRES Shareholders (subject to the minimum holdings requirements
described below) request that CBC register shares of CBC Common held by them,
CBC will use its best efforts to effect such a registration (a "Demand
Registration"). CBC is obligated to use its best efforts to initiate two
Demand Registrations during its 1998 fiscal year, two during its 1999 fiscal
year and two during the period commencing at the beginning of fiscal year 2000
and ending at the end of fiscal year 2002. Each Demand Registration is
required to be firmly underwritten by underwriters selected by the Principal
KRES Shareholders requesting registration, with CBC's consent. CBC agreed to
use its best efforts to keep the first Demand Registration requested during
its 1998 fiscal year effective for a period of 90 days and, in the case of
each other Demand Registration, for a period of 60 days. Apollo's rights
pursuant to the Demand Registration provisions of the KRES Registration Rights
Agreement terminate on the earliest to occur of (i) the date when all shares
of CBC Common held by Apollo may be sold under Rule 144 during any 90-day
period, (ii) one year from the Effective Time of the Merger, provided CBC has
filed certain reports it is required to file pursuant to the Exchange Act or
(ii) two years from the Effective Time of the Merger.
 
                                      91
<PAGE>
 
  If shares held by Apollo are requested to be included in connection with the
first Demand Registration, if any, initiated during CBC's 1998 fiscal year,
but are limited as a result of marketing factors as advised by the
representative of the underwriters of such registration, than after the
closing of such registration CBC agreed to use its best efforts to register up
to 200,000 shares held by Apollo which were excluded from such registration
(the "Supplemental Apollo Demand Registration"). The Supplemental Apollo
Demand Registration will be effected pursuant to Rule 415 of the Securities
Act, which generally provides for an offering to be made on a continuous
basis. Pursuant to the KRES Registration Rights Agreement, CBC agreed to keep
such registration effective for a period equal to the earlier of the date
Apollo has completed the distribution described in the registration statement
or 60 days. Apollo's rights pursuant to the Supplemental Apollo Demand
Registration are not assignable and terminate on the earlier to occur of (i)
the date Apollo's Demand Registration rights terminate as described above or
(ii) the end of CBC's 1998 fiscal year.
 
  In addition, if after December 31, 1997 CBC determines to register any CBC
Common Stock for its own account or for the account of any entity exercising
registration rights in connection with a firmly underwritten offering solely
for cash (other than pursuant to (i) a requested registration as described
above, (ii) an employee benefit plan or dividend reinvestment or similar plan,
(iii) a reorganization, reclassification, merger, consolidation or
acquisition, (iv) a registration which does not permit secondary sales or (v)
antitakeover measures or transactions by CBC), CBC will use its best efforts
to include in such registration all shares of CBC Common Stock requested to be
included by the Principal KRES Shareholders (a "Piggyback Registration"). The
right of any Principal KRES Shareholder to participate in any such requested
registration is conditioned upon the holder's participation in the
underwritten offering and the inclusion of such holder's shares of CBC Common
Stock in the underwriting. CBC agreed to use its best efforts to keep a
Piggyback Registration effective for a period of 90 days. The Principal KRES
Shareholder's Piggyback Registration rights terminate six years after the date
of the KRES Registration Rights Agreement, unless such request is with respect
to shares of CBC Common issued pursuant to exercise of the Warrants issued in
connection with the Merger, in which case such rights terminate eight years
after the date of the KRES Registration Rights Agreement.
 
  Under the KRES Registration Rights Agreement, the right to request CBC to
register shares of CBC Common Stock is exercisable only by the Principal KRES
Shareholders holding (i) with respect to the first request made prior to the
end of CBC's 1998 fiscal year, not less than 500,000 shares of CBC Common
Stock issued pursuant to the Merger, and (ii) with respect to all other
requests for registration, not less than 50% of the then-outstanding shares of
CBC Common Stock issued to all the Principal KRES Shareholders pursuant to the
Merger (provided such 50% constitutes at least 750,000 shares of CBC Common.
 
  Other than as set forth above with respect to the Supplemental Apollo Demand
Registration, the registration rights under the KRES Registration Rights
Agreement may be transferred only to a transferee of not less than 250,000
shares of CBC Common.
 
DELAWARE ANTI-TAKEOVER LAW
 
  CBC is subject to the "business combination" statute of the Delaware General
Corporation Law (Section 203). In general, such statute prohibits a publicly
held Delaware corporation from engaging in a "business combination" with any
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an "interested stockholder," unless (i)
such transaction is approved by the board of directors prior to the date the
interested stockholder obtains such status, (ii) upon consummation of such
transaction, the "interested stockholder" beneficially owned at least 85% of
the voting stock of the corporation outstanding at the time the transaction
commenced, excluding for purposes of determining the number of shares
outstanding those shares owned by (a) persons who are directors and also
officers and (b) employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer, or (iii) the "business
combination" is approved by the board of directors and authorized at an annual
or special meeting of stockholders by the affirmative vote of at least 66 2/3%
of the outstanding voting stock which is not owned by the "interested
stockholder." A "business combination" includes mergers, asset sales and other
transactions
 
                                      92
<PAGE>
 
resulting in financial benefit to the "interested stockholder." An "interested
stockholder" is a person who, together with affiliates and associates, owns
(or within three years, did own) beneficially 15% or more of a corporation's
voting stock. The statute could prohibit or delay mergers or other takeover or
change in control attempts with respect to CBC and, accordingly, may
discourage attempts to acquire CBC.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the CBC Common is The Bank of New York.

BOARD COMMITTEES; COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  There are currently five committees of the CBC Board: an Executive
Committee, a Compensation Committee, an Audit Committee, an
Acquisition/Investment Committee and a Corporate Governance Committee.
 
  The Executive Committee has four members--Messrs. Didion, Beban, Haeckel and
Stafford, however, only two members of such Committee vote, Messrs. Didion and
Beban. The Executive Committee acts on behalf of the Board when the Board is
not in session.
 
  The Compensation Committee members are Messrs. Blum, Malek, Ueberroth and
Wilson. The Compensation Committee determines the salaries of the Chairman and
Chief Executive Officer and, upon the recommendation of the Chief Executive
Officer, the salaries and incentive compensation of the President and the
Chief Financial Officer. The Compensation Committee also authorizes the
adoption of employee benefit plans (other than plans which involve more than
250,000 shares of CBC Common) and makes grants of stock options, restricted
stock awards and all other stock related incentive compensation awards to
employees and directors pursuant to plans adopted by CBC. Outside directors
comprise all of the members of the Compensation Committee.
 
  The members of the Audit Committee are Messrs. Anderson, D'Aniello and
Leach, who are outside directors of CBC. The purpose of the Audit Committee is
to recommend a firm of independent public accountants to be appointed by the
CBC Board subject to stockholder ratification, review CBC's annual
consolidated financial statements and consult with the representatives of the
independent public accountants and the Chief Financial Officer and Principal
Accounting Officer with regard to the adequacy of internal controls.
 
  The Acquisition/Investment Committee members are Messrs. Blum, Didion,
Malek, Ueberroth and Wilson. The purpose of the Acquisition/Investment
Committee is to authorize the undertaking by CBC of definitive negotiations
with respect to any acquisition or investment that contemplates the issuance
of any class of CBC's stock up to $25 million or the aggregate cost of which
is $10 million or more but not more than $25 million. Acquisitions with a cost
of over $25 million require approval of the CBC Board. Cost includes the
purchase price of the acquisition plus any long-term indebtedness assumed.
 
  In December 1996, the CBC Board approved the establishment of a Corporate
Governance Committee, which is composed of three members. The Committee did
not meet in 1996. The members of the Corporate Governance Committee are
Messrs. Anderson, Leach and Malek. The purpose of the Corporate Governance
Committee is to oversee matters related to corporate governance, including the
process of nominating directors for election and to nominate directors for
election. The Corporate Governance Committee will consider nominees
recommended by stockholders but has not yet established procedures for
stockholders to follow in submitting recommendations.
 
DIRECTOR'S FEES
 
  Each of the directors of CBC who is not also an executive officer is
entitled to receive a fee of $2,500 for attendance at each meeting of the CBC
Board, $2,500 for attendance at each meeting of a board committee which does
not coincide with a CBC Board meeting and an annual retainer of $15,000. No
director received compensation from CBC for services as a director in excess
of $27,500 in 1996. Non-employee directors are reimbursed for their expenses
for each meeting attended. In 1993, below market options were granted to
certain non-employee directors in partial payment of directors' fees. In
October 1996, the Compensation Committee (Messrs. Blum, Ueberroth and Wilson
abstaining) granted each of Messrs. Blum, Ueberroth and Wilson a 10,000 share
stock option under CBC's 1991 Service Providers Stock Option Plan exercisable
at the initial public offering price of $20.00 per share and vesting over
three years. CBC is considering, as part of the 1991 Service Providers Stock
Option Plan, the adoption of a longer term stock option program for its
independent directors.

(1) Bonus for each year is paid in the first quarter of the following year.
    Pursuant to CBC's Deferred Compensation Plan, Mr. Didion elected to defer
    his entire bonuses in 1994, 1995 and 1996, Mr. Stafford elected to defer a
    substantial portion of his bonuses in 1995 and 1996, and Mr. Kallis
    elected to defer all or a substantial portion of his bonuses in 1994, 1995
    and 1996. A substantial portion of such deferred amounts will be invested
    in shares of CBC Common.
 
(2) With respect to bonuses payable for 1994 and 1995, under CBC's Deferred
    Compensation Plan, an individual who elected to defer any of such bonus
    for investment in shares of CBC's Common was credited with such shares
    based on the appraised value of the shares at the time the election to
    defer was made. The amounts shown represent the difference between the
    aggregate appraised value of such shares at the time the bonus was paid
    and the aggregate appraised value of such shares at the time the election
    to defer was made. The amounts shown relate to bonuses payable in the
    first quarter of the following year.
 
(3) Consists of each individual's allocable share of profit sharing
    contributions in the form of shares of CBC Common made by CBC to CBC's
    Capital Accumulation Plan, based on the value of the stock at the time of
    contribution based on the appraised or market value of CBC Common.
 
(4) Pursuant to CBC's Equity Incentive Plan, a restricted stock purchase plan,
    in 1996 shares of CBC Common were purchased by such individual for a
    purchase price of $10 per share (the appraised value of the CBC Common at
    the time of such purchase), which was paid by delivery of a full recourse
    promissory note. The notes bear interest at the rate of 6.84% per annum
    which may be forgiven if the executive's performance produces a high
    enough level of bonus (approximately $7,500 in interest is forgiven for
    each $10,000 of

   bonus). The aggregate number and value of such shares held by the
   individuals named above as of December 31, 1996 (based on the last reported
   sale price of the Common Stock on such date as reported by The Nasdaq Stock
   Market, which was $20.00) and net of the purchase price of such shares was
   as follows: Mr. Didion--175,027 ($1,750,270); Mr. Beban--53,910 ($539,100);
   Mr. Stafford--70,750 ($707,500); and Mr. Kallis--42,750 ($427,500). The
   shares vest at the rate of 5 percent per quarter commencing December 31,
   1995. As a result of bonuses paid in 1997 for 1996, all interest on the
   various promissory notes for 1996 was forgiven.
 
(5) Mr. Stafford's employment by CBC commenced in July 1995.
 
(6) Represents the appraised value of restricted stock awards at the date of
    grant. The aggregate number of shares and value of restricted stock
    (excluding stock issued pursuant to CBC's Equity Incentive Plan and stock
    issued in prior years and no longer subject to any specified vesting
    period) held by the individuals named above as of March 31, 1997 (based on
    the last reported sale price of the CBC Common on such date as reported by
    The Nasdaq Stock Market) was as follows: Mr. Kallis--5,000 ($100,000); and
    Mr. Stafford--20,000 ($400,000). The shares awarded to Mr. Stafford vest
    at the rate of 20 percent per year. Shares of restricted stock issued in
    prior years that are no longer subject to vesting are included in the
    table under "Principal Stockholders" above. The holders of shares of
    restricted stock are entitled to receive dividends on such shares to the
    extent dividends are paid on the CBC Common.
 
  At a meeting of the CBC Board held on May 20, 1997, the CBC Board authorized
the compensation committee to negotiate an employment agreement containing a
compensation program for Mr. Didion effective January 1, 1997 which includes
(i) a salary increase of $100,000 to $500,000, (ii) an annual bonus of between
0 and 200% of salary based upon CBC's achieving the EBITDA target designated
by the Compensation Committee of the CBC Board, which for 1997 is $68.1
million (with the bonus subject to a reduction of up to 25% based upon an
individual performance assessment by the Compensation Committee) and (iii) an
option grant for 200,000 shares of CBC Common at their fair market value on
the day of grant. Subsequent to the Board Meeting, the Compensation Committee
granted Mr. Didion a stock option for 200,000 shares which vests at the rate
of approximately 3.23% per month. The option price is $21.50, the fair value
on the date of grant. On May 23, 1997, the Company and Mr. Didion entered into
an employment agreement containing the compensation program described above.
In addition, the employment agreement provides that if Mr. Didion is
terminated without cause, his 200,000 share stock option fully vests and he is
entitled to a lump sum payment equal to approximately 2.7 times his annual
salary. If such a termination occurs during the twelve month period following
a change of control of the Company, the severance amount is subject to
reduction for any amounts Mr. Didion earns for services rendered to the
Company during the two year period following such termination and also is
subject to reduction to the level necessary to avoid the excise tax imposed by
Section 4999 of the Code.

 Board Compensation Committee Report on Executive Compensation
 
  CBC's policies relating to compensation of its executive officers and other
senior executives are intended to provide incentives to attract, retain and
reward executives in order to enhance CBC's profitability and performance.
This goal is achieved in part by materially linking each individual
executive's compensation with the results achieved by such executive.
 
  Compensation of each of the named executive officers as well as other senior
executives consists of a base salary and annual incentive compensation. Base
salaries are generally below competitive levels as CBC relies significantly on
annual and longer term incentive compensation to attract, retain and motivate
senior managers.
 
  Annual incentive compensation, which is generally paid in cash, is tied to
CBC's financial performance and the results achieved by each individual
executive in the preceding fiscal year. The annual incentive compensation
actually paid to each executive is based on CBC's level of financial
performance and the executive's achievement of individual performance goals
established at the beginning of the year. Performance goals range from
specific financial goals (such as sales growth, margin improvement or cost
reductions) to strategic goals (such as increased market share, new product
development and innovation and cross-selling) to management goals (such as
productivity and quality improvement and personnel matters). Specific weighing
is assigned to each identified goal. At the end of the year, performance of
these goals is determined on an arithmetic scale with the pre-established
weighing.
 
  The Chief Executive Officer's annual incentive compensation, like that of
other executives, is tied to CBC's financial performance and the results
achieved by the Chief Executive Officer as evaluated by the Compensation
Committee. The Chief Executive Officer's annual incentive compensation for
1996 was based on the significant improvement in CBC's operating results in
1996 over 1995. Income before interest taxes, depreciation and amortization
increased to $62.0 million from $41.5 million in 1995, and CBC had net income
in 1996 of $24.2 million (excluding the effect of recorded tax benefits
related to projected future taxable income for 1996) compared to net income in
1995 of $7.4 million. In the future the Chief Executive Officer's annual
incentive compensation will be dependent upon achieving an EBITDA target
agreed upon for each year as follows:

       130%........................................................     150%
       140%........................................................     200%
</TABLE>
 
  The Chief Executive Officer's Annual incentive for any year may be reduced
by the Compensation Committee by up to 25% if he fails to meet specific
personal goals established by the Committee for that year.
 
  Executive officers and other senior officers are also provided longer term
incentive compensation through grants of restricted stock awards and stock
options which vest over time. The Compensation Committee believes that stock
option grants provide an incentive to senior management to view CBC from the
perspective of equity shareholders because such options provide value to the
recipient only when the value of CBC's stock increases above the grant price
of the options. Grants of restricted stock provide the same incentive. In
determining the grants of and recommendations of grants of restricted stock
and stock options to individual executives (other than to the Chief Executive
Officer), the Chief Executive Officer considers, among other things, the level
of responsibility and contribution and anticipated performance requirements of
each individual.
 
  In 1996 the Compensation Committee of the CBC Board adopted the 1996 Equity
Incentive Plan (the "Equity Incentive Plan") and the CBC Board reserved
550,000 shares of CBC Common for issuance thereunder.
 
                                      102
<PAGE>
 
The purpose of the plan is to offer selected senior executives an opportunity
to acquire a proprietary interest in the success of CBC, or to increase such
interest, by purchasing shares of CBC Common. In 1996 an aggregate of 510,906
shares were sold to senior executives for a purchase price equal to $10 per
share. See Note 6 to "Executive Compensation--Summary Compensation Table"
above.
 
  In 1993 the Internal Revenue Code was amended to eliminate the deduction for
compensation in excess of $1 million per year paid to the chief executive
officer and the four top-paid executive officers of public reporting
companies. CBC currently does not intend to limit compensation to its
executive officers because of limits on deductions under the Internal Revenue
Code.
 
  The Compensation Committee believes that its actions are, and have been,
consistent with CBC's policies as noted above and in the best interests of
CBC's stockholders.
 
  The foregoing report has been furnished by Messrs. Blum, Malek, Ueberroth
and Wilson. The Compensation Committee is appointed by the CBC Board and
consists of outside, independent directors.
 
  Stock Performance Graph. Set forth below is a graph comparing the yearly
percentage change in the cumulative total stockholder return on CBC Common
with the cumulative total stockholder return of (i) the Nasdaq Market Index
and (ii) a peer group index consisting of the common stock of Grubb & Ellis
Co., a commercial real estate brokerage company traded on the New York Stock
Exchange, for the period from December 31, 1991 through December 31, 1996.
Cumulative total stockholder return consists of change in stock price and
cumulative dividends, assuming dividend reinvestment. The amount used for the
stock price of CBC Common for periods prior to November 26, 1996 when CBC
Common commenced trading on Nasdaq National Market is the appraised value for
purposes of CBC's Capital Accumulation Plan of CBC's Class B-2 Common Stock
(which converted into CBC Common on a one-for-one basis on December 2, 1996).
The appraised value reflected a discount applied by the outside appraisal firm
due to CBC's stock not being publicly traded and being subject to numerous
restrictions on transfer. The comparisons in this table are required by the
Securities and Exchange Commission and are not intended to forecast or be
indicative of possible future performance of CBC's stock.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  The CBC Certificate limits the liability of its directors for monetary
damages for breach of their fiduciary duty as directors, except for liability
that cannot be limited under the Delaware General Corporation Law ("Delaware
Law"). Delaware Law provides that a corporation may eliminate or limit the
personal liability of a director to the corporation or its stockholders, for
monetary damages for breach of their fiduciary duty as directors, except for
liability (i) for any breach of their duty of loyalty to CBC or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payment of dividend or unlawful stock repurchase or redemption, as provided
Section 174 of the Delaware Law, or (iv) for any transaction from which the
director derived an improper personal benefit.
 
  CBC's Certificate also provides that CBC shall indemnify its directors and
officers to the fullest extent permitted by the Delaware Law. CBC has entered
into separate indemnification agreements with its directors that could require
CBC, among other things, to indemnify them against certain liabilities that
may arise by reason of their status or service as directors and to advance
their expenses incurred as a result of any proceeding against them as to which
they could be indemnified. CBC believes that the limitation of liability
provision in its Certificate of Incorporation and the indemnification
agreements will facilitate CBC's ability to continue to attract and retain
qualified individuals to serve as directors and officers of CBC.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  On May 23, 1997, the Company and Mr. Didion entered into an employment
agreement which provides for (i) an annual salary of $500,000, (ii) an annual
bonus of between 0 and 200% of such salary based on CBC's achieving the EBITDA
target designated by the Compensation Committee of the CBC Board, which for
1997 is $68.1 million (with the bonus subject to a reduction of up to 25%
based upon an individual performance assessment by the Compensation Committee)
and (iii) an option grant for 200,000 shares of CBC Common at an exercise
price of $21.50 (the fair market value on the date of grant), which vests at
the rate of approximately 3.23% per month. In addition, the employment
agreement provides that if Mr. Didion is terminated without cause, his 200,000
share stock option fully vests and he is entitled to a lump sum payment equal
to approximately 2.7 times his annual salary. If such a termination occurs
during the twelve month period following a change of control of the Company,
the severance amount is subject to reduction for any amounts Mr. Didion earns
for services rendered to the Company during the two year period following such
termination and also is subject to reduction to the level necessary to avoid
the excise tax imposed by Section 4999 of the Code.
 
  Mr. Clotfelter, a director of CBC and president of Westmark, owns 85% of the
stock of Prescott, Inc. ("Prescott"), a property management company based in
Seattle, Washington. In 1994, CBC completed the acquisition of certain assets
of Prescott, which consisted of property management agreements, for an
aggregate purchase price of $175,000. In connection with the acquisition of
assets from Prescott, in 1994 Mr. Clotfelter incurred indebtedness to CBC in
an aggregate principal amount of $106,000. The indebtedness bore interest at
nine percent, which was determined under CBC's policies for employee loans,
and the largest amount outstanding at any time (including principal and
interest) was $109,000. The loan was paid in full as of March 20, 1996.
 
  In February 1995, CBC retained the law firm of McDermott, Will & Emery, to
which Mr. Anderson, a director of CBC, is counsel, to provide services to CBC
consisting of legal counsel in connection with CBC's activities with certain
federal agencies.
 
  In connection with CBC's acquisition of L.J. Melody CBC entered into an
Employment Agreement, dated as of July 1, 1996 ("Melody Employment
Agreement"), pursuant to which CBC agreed to employ Mr. Melody as President
and Chief Executive Officer of L.J. Melody through June 30, 2001. Pursuant to
the Melody Employment Agreement, Mr. Melody is entitled to receive (a) a base
salary of $26,000 per month and (b) incentive compensation equal to 10% of
L.J. Melody's annual pre-tax net income, after deducting certain costs and
expenses relating to employee benefits, interest on working capital,
allocation of overhead and other items provided by CBC. Total incentive
compensation payments to Mr. Melody in 1996 were $198,844.

  Pursuant to CBC's Equity Incentive Plan, a restricted stock purchase plan,
in 1996 shares of CBC Common were purchased by the executive officers and
Directors named below for a purchase price of $10 per share (the appraised
value of the Common Stock at the time of such purchase), which was paid by
delivery of a full recourse promissory note. The notes bear interest at the
rate of 6.84% per annum which may be forgiven if the executive's performance
produces a high enough level of bonus (approximately $7,500 in interest is
forgiven for each $10,000 of bonus). The aggregate number of shares purchased
and the amount of the promissory note delivered by the following individuals
were: Mr. Beban--53,910 ($539,100); Mr. Clotfelter--33,750 ($337,500); Mr.
Didion--175,027 ($1,750,270); Mr. Kallis--42,750 ($427,500); Mr. Stafford--
70,750 ($707,500); and Mr. Stanfill--54,383 ($543,830). As a result of bonuses
paid in 1997 for 1996 all interest accrued in 1996 on the various promissory
notes was forgiven. In each case, the original principal amount of the
promissory note is equal to the highest amount which was outstanding during
1996 and is also equal to the amount currently outstanding under each such
note.
 
  Richard C. Blum & Associates, Inc., of which Mr. Blum, a director of CBC, is
Chairman and President, and CBC have tentatively agreed to form a joint
venture to opportunistically acquire and develop property on behalf of mutual
clients. The specifics of any venture are still to be determined.
 
  CBC and CB Group have entered into Indemnity Agreements with each of their
present directors, some of whom are also officers of CBC.

CBC'S CREDIT AGREEMENTS
 
  The following summary is a description of certain provisions of CBC's Senior
Secured Credit Agreement and Senior Subordinated Credit Agreement that are
currently in effect. Such summary does not purport to be complete and is
qualified in its entirety by all of the provisions of such agreements.
 
 Senior Secured Debt Repayment and Amendments
 
  Approximately $52.8 million of indebtedness ("Term Debt"), including $18.0
million of indebtedness secured by certain mortgages (the "Mortgage Debt"), is
outstanding under CBC's Senior Secured Credit Agreement. The Senior Secured
Credit Agreement also provides for a $20 million revolving credit facility
("Revolving Credit Facility A") of which approximately $19.4 million is
currently outstanding including letters of credit and, effective with the KRES
Merger an additional $50 million revolving credit facility ("Revolving Credit
Facility B"). Prior to the KRES Merger the maximum limit under Revolving
Credit Facility B is $10 million. No indebtedness is outstanding under
Revolving Credit Facility B. In November 1996, the Senior Secured Credit
Agreement was amended to contain substantially the terms and conditions
described below. All indebtedness outstanding under the Senior Secured Credit
Agreement other than that outstanding under Revolving Credit Facility B bears
interest at a rate equal to, at CBC's option, LIBOR plus 250 basis points or
the prime rate plus 150 basis points. Amounts outstanding on Revolving Credit
Facility B bears interest at a rate equal to, at CBC's option, LIBOR plus 300
basis points or the prime rate plus 200 basis points. Principal payments on
the Term Debt of $2.625 million each are due quarterly with final payment of
$5.5 million on December 31, 2001. The availability period of Revolving Credit
Facility A ends December 31, 2001. Revolving Credit Facility B was converted
into a facility that can be used for acquisitions. Effective as of the closing
of the Merger there will be $50 million available under Revolving Credit
Facility B, approximately $45 million of which will be used to pay off KRES
bank indebtedness. Amounts borrowed for this purpose must be repaid within 6
months of the closing. Principal payments on amounts outstanding under such
facility will be paid quarterly at the rate of 5% of the outstanding balance
but the entire principal amount becomes due and payable six months after the
closing of the KRES acquisition.
 
                                      105
<PAGE>
 
  Subject to certain exceptions and limitations, CBC is obligated to make
prepayments in respect of indebtedness outstanding under the Senior Secured
Credit Agreement equal to (a) 100% of the net cash proceeds from any sale or
other disposition of assets resulting in aggregate consideration in excess of
$1 million in any twelve-month period, or (b) 25% of the net cash proceeds
from a sale of CBC's capital stock. In general, prepayments are applied first
to Term Debt (other than the Mortgage Debt) and then to indebtedness
outstanding under Revolving Credit Facility A and Revolving Credit Facility B,
pro rata according to the respective principal amounts then outstanding
thereunder, and then to the Mortgage Debt. A prepayment required to be made as
a result of the sale of real property which secures the Mortgage Debt is
applied, first, to Mortgage Debt, next to other Term Debt, and, finally, to
indebtedness outstanding under Revolving Credit Facility A and Revolving
Credit Facility B, pro rata according to the respective principal amounts then
outstanding thereunder. All of the foregoing prepayments in respect of
Revolving Credit Facility A and Revolving Credit Facility B permanently reduce
the amount available under the respective revolving credit facility by the
amount of the prepayment.
 
  The obligations of CBC under the Senior Secured Credit Agreement are secured
by substantially all of the assets of CBC and its subsidiaries, including
cash, accounts receivable, equipment, intellectual property, and real property
as well as the stock of certain of CBC's subsidiaries.
 
  The Senior Secured Credit Agreement, as amended, contains certain financial
tests which CBC is obligated to satisfy. These tests include a leverage ratio,
an interest coverage ratio, a fixed charges coverage ratio, and a senior loan
debt service coverage ratio. The Senior Secured Credit Agreement also contains
a number of affirmative and negative covenants covering such matters as
maintenance of corporate existence, payment of taxes, maintenance of
properties, maintenance of insurance, the granting or existence of certain
liens, incurrence of additional indebtedness, payment of dividends,
investments, capital expenditures, sales or other dispositions of property,
payments in respect of subordinated debt, and compliance with ERISA.
 
  The financial and other covenants in the Senior Secured Credit Agreement may
prevent CBC from carrying out a transaction or taking other action otherwise
determined by the Board of Directors to be in CBC's best interests. For
example, the covenant regarding limitations on incurrence of indebtedness or
regarding limitations on liens may preclude CBC and its subsidiaries from
making an acquisition (whether by merger or in some other form). Although CBC
would intend to seek a waiver or modification of these covenants under
appropriate circumstances, there can be no assurance that CBC will be able to
obtain such a waiver or modification upon terms and conditions acceptable to
CBC on a timely basis, or at all. As a result, the covenants in the Senior
Secured Credit Agreement may effectively preclude CBC from pursuing its
strategy of growth through acquisitions or delay CBC's ability to carry out
that strategy.
 
  The Senior Secured Credit Agreement contains a number of events of default
(each an "Event of Default"), including, without limitation, failure to make
required payments or prepayments of principal or interest, breach of covenant,
breach of a representation or warranty in a material respect, default in
respect of other indebtedness in excess of $500,000, insolvency of CBC or any
of its subsidiaries, failure to discharge or pay or obtain a stay in respect
of a judgment in excess of $100,000, certain events relating to ERISA
involving a liability or payment in excess of $100,000, a change of control,
as defined below, and a material adverse change in the business, assets,
prospects, results of operation or the financial condition of CBC or of CBC
and its subsidiaries taken as a whole. Change of control is defined under the
Senior Secured Credit Agreement as (i) the acquisition, by any person (other
than CBC's Capital Accumulation Plan), of more than 25% of the total voting
power of all classes of CBC's equity securities (excluding the acquisition by
the Underwriters of Common Stock in the Offering) or (ii) a change in the
board of directors of CBC such that board members at the beginning of any one-
year period no longer constitute a majority of the board at the end of such
period, or (iii) CBC ceases to own 100% of the outstanding common stock of
CBC's primary operating subsidiary. Upon the occurrence of an Event of Default
(other than an Event of Default relating to insolvency), the lenders under the
Senior Secured Credit Agreement have the right, in addition to other available
remedies, to terminate the revolving credit facilities, to declare all
indebtedness outstanding thereunder immediately due and payable, and to
thereafter pursue applicable remedies against any and all collateral securing
payment of such indebtedness.

 Senior Subordinated Debt Amendments
 
  Approximately $65.9 million of indebtedness is outstanding under CBC's
Senior Subordinated Credit Agreement. The Senior Subordinated Credit Agreement
was also amended and restated in November of 1996. As so amended such credit
agreement contains financial and other covenants and events of default no more
restrictive than those under the Senior Secured Credit Agreement. Interest on
the senior subordinated debt is LIBOR plus 125 basis points from January 1,
1997 through December 31, 1998, LIBOR plus 200 basis points during 1999, LIBOR
plus 300 basis points during 2000 and LIBOR plus 400 basis points during 2001
and beyond. Interest in excess of LIBOR plus 125 basis points is deferred and
added to principal until the final maturity date. The principal outstanding
under the Senior Subordinated Credit Agreement is due and payable in full on
July 23, 2002 and may not be prepaid while any amount is unpaid under the
Senior Secured Credit Agreement.
 
REFINANCING OF SENIOR SECURED AND SENIOR SUBORDINATED DEBT
 
  CBC is in the process of refinancing its existing senior and subordinated
debt (including debt related to the acquisition of L.J. Melody & Company and
Westmark Realty Advisors) and expanding its revolver and acquisition
facilities. However, there can be no assurance that the refinancing can be
achieved.

             COMPARISON OF RIGHTS OF STOCKHOLDERS OF CBC AND KRES
 
  The rights of CBC shareholders are governed by CBC's Certificate of
Incorporation, its Bylaws (the "CBC Bylaws") and the Delaware General
Corporation Law (the "DGCL"). The rights of KRES shareholders are governed by
KRES's Certificate of Incorporation, its Bylaws (the "KRES Bylaws"), the
Stockholders Agreement, and the DGCL. See, "PROPOSAL FOR NOMINATION AND
ELECTION OF CBC DIRECTORS--Stockholders Agreement and Registration Rights
Agreement." Following consummation of the Merger, the rights of holders of
KRES Common who become holders of CBC Common will be governed by CBC's
Certificate of Incorporation, the CBC Bylaws and the DGCL. The following is a
summary of material differences between the rights of holders of CBC Common
and the rights of holders of KRES Common under their respective Certificates
of Incorporation and Bylaws. This comparison is qualified in its entirety by
reference to CBC's Certificate of Incorporation, the CBC Bylaws, KRES's
Certificate of Incorporation and the KRES Bylaws.
 
BOARD OF DIRECTORS
 
  KRES. The KRES Bylaws provide that the number of directors shall be fixed
from time to time by resolution of the KRES Board. The current number of
directors is fixed at seven (7).
 
  CBC. The CBC Bylaws provide that the number of directors shall be one or
more, as determined from time to time by resolution of the CBC Board. The
current number of directors authorized is nineteen (19), subject to
consummation of the merger, if the merger is not consummated, the number of
directors authorized shall be fifteen (15). There are currently fifteen (15)
directors serving on the CBC Board.
 
FILLING VACANCIES ON THE BOARD OF DIRECTORS
 
  KRES. The KRES Bylaws provide that a vacancy on the KRES Board may be filled
solely by the affirmative vote of a majority of the remaining directors then
in office, even though such majority is less than a quorum.
 
  CBC. The CBC Bylaws provide that a vacancy on the CBC Board relating to a
director who is to be elected by all stockholders entitled to vote, may be
filled by the affirmative vote of a majority of the remaining directors then
in office, even though such majority is less than a quorum. Whenever the
holders of any class or classes of stock or series thereof are entitled to
elect one or more directors by the CBC Certificate, vacancies and newly
created directorships of such class or classes or series thereof may be filled
by a majority of the directors elected by such class or classes or series
thereof then in office, or by a sole remaining director so elected.
 
AMENDMENT OF CERTIFICATE OF INCORPORATION
 
  KRES. Under the DGCL, an amendment to the Certificate of Incorporation
generally requires the recommendation of the board of directors, the approval
of a majority of all shares entitled to vote thereon, voting together as a
single class and the approval of a majority of the outstanding stock of each
class entitled to vote thereon.
 
  CBC. Under the DGCL, an amendment to the Certificate of Incorporation
generally requires the recommendation of the board of directors, the approval
of a majority of all shares entitled to vote thereon, voting together as a
single class and the approval of a majority of the outstanding stock of each
class entitled to vote thereon. In addition, the CBC Certificate provides that
so long as any CBC Series A-1, CBC Series A-2 or CBC Series A-3 Preferred
Stock remains outstanding, CBC shall not amend its certificate of
incorporation so as to change the rights preferences or privileges of any
series of CBC's Preferred Stock without the vote or written consent by the
holders of a majority of the CBC A-1 Preferred, CBC A-2 Preferred and CBC A-3
Preferred, voting together as a single class.

  KRES. Holders of KRES Common are entitled to one vote per share on all
matters submitted to a vote of shareholders. KRES does not allow cumulative
voting.
 
  CBC. Holders of CBC Common vote as a single class together with the holders
of CBC A-1 Preferred and holders of CBC A-2 Preferred with respect to all
matters submitted to a vote of shareholders. Holders of CBC A-1 Preferred have
two votes per share and holders of CBC A-2 Preferred have one vote per share.
CBC does not allow cumulative voting.
 
DIVIDENDS
 
  KRES. Holders of KRES Common receive dividends when, as and if declared by
the KRES Board, subject to Section 170 of the DGCL.
 
  CBC. Holders of CBC Common receive dividends when, as and if declared by the
CBC Board, subject to Section 170 of the DGCL and to the rights of the holders
of CBC Preferred. Until all accrued and unpaid dividends on the CBC Preferred
Stock shall have been paid or declared and set apart during any fiscal year,
CBC may not pay or declare and set apart any dividends on CBC Common. Whenever
any dividends are paid on the CBC Common, the holders of CBC Preferred are
entitled to an amount per share equal to 60% of the amount per share paid on
the CBC Common (such amount is any addition to any preference dividend due on
the Preferred Stock in accordance with its terms).
 
LIQUIDATION
 
  KRES. Upon a liquidation, dissolution or winding up of KRES, after the
payment of claims in accordance with the DGCL, the holders of KRES Common
would be entitled to share pro rata in the remaining assets of KRES based on
their respective shareholdings.
 
  CBC. Upon a liquidation, dissolution or winding up of CBC, after the payment
of claims in accordance with the DGCL, (i) first, the holders of CBC Preferred
shall be entitled to receive all accrued and unpaid dividends relating to the
CBC Preferred (together with interest thereon), (ii) second, the holders of
CBC Preferred and the holders of CBC Common shall each be entitled to receive
an amount equal to $10.00 per share of Preferred Stock or Common as the case
may be and (iii) finally any excess assets shall be distributed such that the
holders of CBC Preferred receive an amount per share equal to 60% of the per
share amount received by the holders of CBC Common.
 
                               APPRAISAL RIGHTS
 
  Holders of shares of KRES Common outstanding at the Effective Time are
entitled to appraisal rights under Section 262 of the Delaware General
Corporation Law, except as otherwise set forth in agreements binding upon any
such holder. Section 262 is reprinted in its entirety as Annex 4 to this Joint
Proxy Statement/Prospectus. The following discussion is not a complete
statement of the law relating to appraisal rights and is qualified in its
entirety by reference to Annex 4. This discussion and Annex 4 should be
reviewed carefully by any holder who wishes to exercise statutory appraisal
rights, if available, or who wishes to preserve the right to do so, as failure
to comply with the procedures set forth herein or therein will result in the
loss of appraisal rights, if available.
 
  A holder of KRES Common who makes the demand described below with respect to
such shares, who continuously is the record holder of such shares through the
Effective Time, who otherwise complies with the statutory requirements of
Section 262, who neither votes in favor of the Merger Agreement nor consents
thereto in writing and who is not otherwise bound by an agreement preventing
it from validly perfecting appraisal rights may be entitled to an appraisal by
the Delaware Court of the fair value of its shares of KRES Common. Except as
set forth herein, holders of KRES Common will not be entitled to appraisal
rights in connection with the Merger. Stockholders of CBC will have no
appraisal rights in connection with the Merger.
 
                                      111
<PAGE>
 
  Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the KRES Meeting, not less than 20 days prior
to the meeting, each constituent corporation must notify each of the holders
of its stock for which appraisal rights are available that such appraisal
rights are available and include in each such notice a copy of Section 262.
This Joint Proxy Statement/Prospectus will constitute such notice to the
holders of KRES Common.
 
  Holders of KRES Common who desire to exercise their appraisal rights must
not vote in favor of the Merger Agreement or the Merger and must deliver a
separate written demand for appraisal to KRES prior to the vote by the holders
of KRES Common on the Merger Agreement and the transactions contemplated
thereby, including the Merger. In addition, certain holders of KRES Common may
not be entitled to appraisal rights if they are bound by any agreement which
restricts their ability to perfect such appraisal rights. Certain stockholders
of KRES are parties to agreements in which they have agreed that, in the event
FS sells all its shares of KRES Common, such holders shall sell their shares
on the same terms and conditions. CBC and KRES reserve the right to assert
that such stockholders have waived their appraisal rights.
 
  A holder of KRES Common who signs and returns a proxy without expressly
directing by checking the applicable boxes on the proxy card enclosed herewith
that its shares of KRES Common be voted against the proposal or that an
abstention be registered with respect to its shares of KRES Common in
connection with the proposal will effectively have thereby waived its
appraisal rights as to those shares of KRES Common because, in the absence of
express contrary instructions, such shares of KRES Common will be voted in
favor of the proposal. See "THE MEETINGS--KRES Proxies." Accordingly, a holder
of KRES Common who desires to perfect appraisal rights with respect to any of
its shares of KRES Common must, as one of the procedural steps involved in
such perfection, either (i) refrain from executing and returning the enclosed
proxy card and from voting in person in favor of the proposal to approve the
Merger Agreement, or (ii) check either the "Against" or the "Abstain" box next
to the proposal on such card or affirmatively vote in person against the
proposal or register in person an abstention with respect thereto. Merely
failing to vote against the Merger will not constitute a waiver of appraisal
rights, except as provided above. A demand for appraisal must be executed by
or on behalf of the holder of record of KRES Common and must reasonably inform
KRES of the identity of the holder of record of KRES Common and that such
record holder intends thereby to demand appraisal of its shares of KRES
Common. A person having a beneficial interest in shares of KRES Common that
are held of record in the name of another person, such as a broker, fiduciary
or other nominee, must act promptly to cause the record holder to follow the
steps summarized herein properly and in a timely manner to perfect whatever
appraisal rights are available. If the shares of KRES Common are owned of
record by a person other than the beneficial owner, including a broker,
fiduciary (such as a trustee, guardian or custodian) or other nominee, such
demand must be executed by or for the record owner. If the shares of KRES
Common are owned of record by more than one person, as in a joint tenancy or
tenancy in common, such demand must be executed by or for all joint owners. An
authorized agent, including an agent for two or more joint owners, may execute
the demand for appraisal for a stockholder of record; however, the agent must
identify the record owner and expressly disclose the fact that, in exercising
the demand, such person is acting as agent for the record owner. If a
stockholder holds shares through a broker who in turn holds the shares through
a central securities depository nominee such as Cede & Co., a demand for
appraisal of such shares must be made by or on behalf of the depository
nominee and must identify the depository nominee as record holder.
 
  A record owner, such as a broker, fiduciary or other nominee, who holds
shares of KRES Common as a nominee for others, may exercise appraisal rights
with respect to the shares held for all or less than all beneficial owners of
shares as to which such person is the record owner. In such case, the written
demand must set forth the number of shares covered by such demand. Where the
number of shares is not expressly stated, the demand will be presumed to cover
all shares of KRES Common outstanding in the name of such record owner.
 
  A holder of KRES Common who elects to exercise appraisal rights, if
available, should mail or deliver its written demand to: Koll Real Estate
Services, 4343 Von Karman Avenue, Newport Beach, California, 92660, Attention:
Herbert L. Roth, Secretary.
 
 
                                      112
<PAGE>
 
  The written demand for appraisal should specify the holder's name and
mailing address, the number of shares of KRES Common owned, and that the
holder is thereby demanding appraisal of its shares. A proxy or vote against
the Merger Agreement will not by itself constitute such a demand. Within ten
days after the Effective Time, the corporation surviving the Merger (the
"Surviving Corporation") will provide notice of the Effective Time to all
holders who have complied with Section 262.
 
  Within 120 days after the Effective Time, either the Surviving Corporation
or any holder of KRES Common who has complied with the required conditions of
Section 262 may file a petition in the Delaware Court, with a copy served on
the Surviving Corporation in the case of a petition filed by a holder of KRES
Common, demanding a determination of the fair value of the shares of all
dissenting holders of KRES Common. There is no present intent on the part of
CBC to file an appraisal petition and holders of KRES Common seeking to
exercise appraisal rights should not assume that the Surviving Corporation
will file such a petition or that the Surviving Corporation will initiate any
negotiations with respect to the fair value of such shares. Accordingly,
holders of KRES Common who desire to have their shares appraised should
initiate any petitions necessary for the perfection of their appraisal rights
within the time periods and in the manner prescribed in Section 262. If
appraisal rights are available, within 120 days after the Effective Time, any
holder of KRES Common who has theretofore complied with the applicable
provisions of Section 262 will be entitled, upon written request, to receive
from the Surviving Corporation a statement setting forth the aggregate number
of shares of KRES Common not voting in favor of the Merger Agreement and with
respect to which demands for appraisal were received by KRES and the number of
holders of such shares. Such statement must be mailed within 10 days after the
written request therefor has been received by the Surviving Corporation.
 
  If a petition for an appraisal is timely filed and assuming appraisal rights
are available, at the hearing on such petition, the Delaware Court will
determine which holders of KRES Common, if any, are entitled to appraisal
rights. The Delaware Court may require the holders of KRES Common who have
demanded an appraisal for their shares and who hold stock represented by
certificates to submit their certificates of stock to the Register in Chancery
for notation thereon of the pendency of the appraisal proceedings; and if any
holder fails to comply with such direction, the Delaware Court may dismiss the
proceedings as to such holder. Where proceedings are not dismissed, the
Delaware Court will appraise the shares of KRES Common owned by such holders,
determining the fair value of such shares exclusive of any element of value
arising from the accomplishment or expectation of the Merger, together with a
fair rate of interest, if any, to be paid upon the amount determined to be the
fair value. In determining fair value, the Delaware Court is to take into
account all relevant factors. In Weinberger v. UOP Inc., the Delaware Supreme
Court discussed the factors that could be considered in determining fair value
in an appraisal proceeding, stating that "proof of value by any techniques or
methods which are generally considered acceptable in the financial community
and otherwise admissible in court" should be considered, and that "fair price
obviously requires consideration of all relevant factors involving the value
of a company." The Delaware Supreme Court stated that in making this
determination of fair value the court must consider market value, asset value,
dividends, earnings prospects, the nature of the enterprise and any other
facts which could be ascertained as of the date of the merger which throw
light on future prospects of the merged corporation. In Weinberger, the
Delaware Supreme Court stated that "elements of future value, including the
nature of the enterprise, which are known or susceptible of proof as of the
date of the merger and not the product of speculation, may be considered."
Section 262, however, provides that fair value is to be "exclusive of any
element of value arising from the accomplishment or expectation of the
merger."
 
  Holders of KRES Common considering seeking appraisal should recognize that
the fair value of their shares determined under Section 262 could be more
than, the same as or less than the consideration they are entitled to receive
pursuant to the Merger Agreement if they do not seek appraisal of their
shares. The cost of the appraisal proceeding may be determined by the Delaware
Court and taxed against the parties as the Delaware Court deems equitable in
the circumstances. Upon application of a dissenting holder, the Delaware Court
may order that all or a portion of the expenses incurred by any dissenting
holder in connection with the appraisal proceeding, including, without
limitation, reasonable attorneys' fees and the fees and expenses of experts,
be charged pro rata against the value of all shares of stock entitled to
appraisal.
 
 
                                      113
<PAGE>
 
  Any holder of KRES Common who has duly demanded appraisal in compliance with
Section 262 will not, after the Effective Time, be entitled to vote for any
purpose any shares subject to such demand or to receive payment of dividends
or other distributions on such shares, except for dividends or distributions
payable to holders of KRES Common of record at a date prior to the Effective
Time.
 
  At any time within 60 days after the Effective Time, any holder of KRES
Common will have the right to withdraw such demand for appraisal and to accept
the terms offered in the Merger; after this period, the KRES Stockholder may
withdraw such demand for appraisal only with the consent of the Surviving
Corporation. If no petition for appraisal is filed with the Delaware Court
within 120 days after the Effective Time, the rights of holders of KRES Common
to appraisal will cease, and such holders will be entitled to receive the
Merger consideration. Inasmuch as the Surviving Corporation has no obligation
to file such a petition, and CBC has no present intention to do so, any holder
of KRES Common who desires such a petition to be filed is advised to file it
on a timely basis. Any holder of KRES Common may withdraw such holder's demand
for appraisal by delivering to the Surviving Corporation a written withdrawal
of its demand for appraisal and acceptance of the Merger consideration, except
(i) that any such attempt to withdraw made more than 60 days after the
Effective Time will require written approval of the Surviving Corporation and
(ii) that no appraisal proceeding in the Delaware Court will be dismissed as
to any holder of KRES Common without the approval of the Delaware Court, and
such approval may be conditioned upon such terms as the Delaware Court deems
just. Any holder of KRES Common who withdraws such holder's demand for
appraisal or who fails to perfect such demand after the Effective Time will be
treated as having made a non-election with respect to its KRES Common.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
TRANSACTIONS WITH THE KOLL COMPANY
 
 Management Services Agreements
 
  In April 1993, KRES entered into a management services agreement (the
"Management Services Agreement") with The Koll Company, a corporation which is
indirectly wholly-owned by Donald M. Koll, a nominee to the CBC Board whereby
(i) The Koll Company, through certain key personnel primarily employed by The
Koll Company, including Mr. Wirta (who is also a nominee to the CBC Board),
provided executive management services to KRES and (ii) KRES provides
management information, personnel and human resources services (including
administration of The Koll Company's 401(k) Plan) to The Koll Company and
certain of its affiliates. Payments by KRES to The Koll Company for Mr.
Wirta's executive management services and occupancy costs for each of the
twelve months ended March 31, 1995 and 1996 totaled $276,000 and $281,000,
respectively. In addition, in March 1995, KRES entered into an agreement with
Koll Real Estate Group, Inc. whereby KRES provides management information
systems and human resource services to Koll Real Estate Group, Inc., an
affiliate of Donald M. Koll, similar to those provided under the Management
Services Agreement.
 
                                      116
<PAGE>
 
Payments by The Koll Company and certain of its affiliates to KRES for
management information, personnel and human resources services provided by
KRES under the Management Services Agreement for the twelve months ended March
31, 1995 and 1996 and the nine months ended December 31, 1996 totaled $1.2
million, $756,000 and $466,000, respectively. As of April 1, 1996, Mr. Wirta
became an employee of KRES and The Koll Company no longer provided executive
management services to KRES under the Management Services Agreement. KRES
continues to provide management information services and personnel and human
resources services to The Koll Company.
 
  Effective July 1, 1993, KRES began paying the costs of health insurance
benefits for The Koll Company and its affiliates. The Koll Company and each
affiliate are billed monthly for their pro-rata portion (based on number of
employees) of the payments. Billings to The Koll Company and its affiliates
for such health insurance benefits for each of the twelve months ended March
31, 1995 and 1996 and the nine months ended December 31, 1996 were
approximately $1.2 million, $1.7 million and $1.2 million, respectively.
 
 License Agreement
 
  Under the terms of an amended license agreement (the "License Agreement") by
and between KRES and The Koll Company dated November 23, 1994, KRES was
granted a perpetual, royalty-free license ("License") to use, and to allow its
subsidiaries to use, the "Koll" name and certain logos associated therewith
("Licensed Marks") solely in connection with the provision of real estate
management services, including property, facility, asset and investment
management services relating to real property ("Licensee Services"). Pursuant
to the License Agreement, The Koll Company retains the right to use and grant
others the right to use the Licensed Marks for any purpose, provided that it
shall not use nor grant a third party the right to use the Licensed Marks in
connection with the provision of Licensee Services. In general, The Koll
Company may only terminate the License if (i) KRES fails to honor the terms of
the License Agreement, including maintaining the quality of the services
associated with the Licensed Marks and protecting against infringement of the
Licensed Marks by third parties, (ii) KRES abandons use of the Licensed Marks
for three consecutive years, or (iii) KRES is deemed insolvent. The License
Agreement will be assigned to CBC as part of the Merger.
 
 Lease Agreements
 
  KRES leases its headquarters office space and some of its regional and field
offices from partnerships in which The Koll Company and Messrs. Koll and Wirta
are partners. The initial rent under each lease was based upon the fair market
value of the premises at the time the lease was signed. KRES is not
responsible for property taxes, insurance or maintenance expenses of the
leased premises under the terms of the leases. Rental payments made by KRES to
partnerships in which The Koll Company and Messrs. Koll and Wirta are partners
totaled $1.4 million, $1.1 million and $1.4 million for the twelve months
ended March 31, 1995 and 1996 and the nine months ended December 31, 1996,
respectively. Two leases for KRES' headquarters were the only leases with
terms in excess of one year and for which annual rental payments exceeded
$100,000 each.
 
 Lease Guaranty
 
  Pursuant to a lease guaranty dated November 15, 1994 (the "Lease Guaranty")
made by KRES for the benefit of a general partnership (in which The Koll
Company and Messrs. Koll and Wirta are partners) and Aetna Life Insurance
Company ("Aetna"), KRES has guaranteed payment and performance by The Koll
Company of a lease agreement covering the building in which KRES' headquarters
are located. KRES subleases its headquarters office space from The Koll
Company. Such general partnership has assigned all of its rights under the
Lease Guaranty to Aetna in connection with a loan in the original principal
amount of $9.0 million made by Aetna to such general partnership.
 
 Agreement Regarding Business Opportunities
 
  Pursuant to a business opportunities agreement (the "Business Opportunities
Agreement") entered into in 1991 by and between KRES and The Koll Company and
its affiliates, KRES was afforded the exclusive right to
 
                                      117
<PAGE>
 
pursue, through subcontracting and otherwise, any and all real property and
asset management opportunities awarded to The Koll Company and its affiliates
by any source (including the Resolution Trust Corporation), other than certain
pension and retirement fund clients to whom a subsidiary of The Koll Company
was providing real property management services as of April 1991. The terms of
the Business Opportunities Agreement provided that it would continue until The
Koll Company owned less than 20% of the outstanding common stock of KMS. In
April 1996 The Koll Company's beneficial ownership of KMS dropped below 20%
and the Business Opportunities Agreement terminated. See "--Recent Stock
Transactions."
 
 Transactions with Partnerships Affiliated with The Koll Company
 
  KRES is responsible for managing properties in which The Koll Company and
Messrs. Koll and Wirta, have an ownership interest. Approximately $9.3
million, or 11.1%, $5.2 million, or 4%, and $3.5 million or 4% of KRES'
management revenue for the twelve months ended March 31, 1995 and 1996 and the
nine months ended December 31, 1996, respectively, was derived from managing
properties that are owned by partnerships which are affiliates of The Koll
Company. The partnerships that own these properties typically include a
financial institution that was responsible for initially financing the
development or acquisition of the project. The management agreements between
KRES and these partnerships typically are negotiated between the financial
partner in the partnerships and KRES and are believed to reflect fair market
value terms. These management agreements are for an indefinite period but
generally provide the property owner with the right to terminate upon 30 days'
prior written notice.
 
STOCKHOLDERS AGREEMENT AND REGISTRATION RIGHTS AGREEMENTS
 
  On January 9, 1997 KRES, FS, KHC, The Koll Company and Apollo entered into a
Third Amended and Restated Stockholders Agreement (the "Stockholders
Agreement") under which AP KMS II was provided certain rights and assumed
certain obligations. In addition, KRES entered into an Amended and Restated
Registration Rights Agreement with Apollo. The Stockholders Agreement provides
that, as long as FS holds a majority of the Voting Securities (as defined
therein) held by FS, KHC and Apollo, the KRES Board and each of its
subsidiaries shall be comprised of seven directors, with FS nominating four
directors, KHC and Apollo each nominating one director and KRES' Chief
Executive Officer (or if KRES has no Chief Executive Officer, the most senior
executive officer of KRES) being the other director. In the event FS does not
continue to hold such a majority of Voting Securities, FS, KHC and Apollo have
agreed, subject to certain exceptions, to vote their shares of KRES Common to
elect up to seven directors in proportion to their respective percentage
ownership of Voting Securities.
 
  In addition, the Stockholders Agreement grants an option (the "Safeco
Option") to FS and Apollo which provides that, since The Koll Company and KHC
did not terminate the Safeco Pledge Agreement by May 11, 1997, FS and Apollo
may, for a period of 60 days after May 11, 1997, exercise such Safeco Option
for an exercise price of $18.00 to purchase shares of KRES Common held by KHC,
the proceeds of which shall be used to cause Safeco to terminate the Safeco
Pledge Agreement. The Safeco Option is exercisable first with respect to those
shares of KRES Common held by KHC which are not subject to an option in favor
of Mr. Wirta or Mr. Rothe and then, subject to certain limitations, with
respect to those shares which are subject to an option in favor of Mr. Wirta.
In no event shall the Safeco Option apply to shares subject to an option in
favor of Mr. Rothe. The Safeco Option is exercisable by FS and Apollo pro rata
with respect to the aggregate shares purchased by each of them from KHC on
March 29, 1996 and April 1, 1996.
 
  KRES has entered into Registration Rights Agreements with FS, KHC and Apollo
in connection with shares of KRES Common which generally provide that each
such party is entitled, under certain conditions, to demand that KRES register
shares of KRES Common owned by such party at various times following a public
offering by KRES.
 
  As a condition to the Merger, the Stockholders Agreement, all Registration
Rights Agreements and all other similar agreements relating to equity
securities of KRES will have been terminated.

           PROPOSAL TO APPROVE CBC'S 1997 EMPLOYEE STOCK OPTION PLAN
 
GENERAL
 
  At the CBC Meeting, CBC stockholders are also being asked to approve CBC's
1997 Employee Stock Option Plan ("1997 Option Plan") which provides for the
grant of stock options to certain employees of CBC. The 1997 Option Plan
provides for the grant of options to purchase up to 700,000 shares of CBC
Common. Set forth below is a summary of the 1997 Option Plan, which is
qualified in its entirety by Annex 5 to this Joint Proxy Statement/Prospectus
which sets forth the full text of the 1997 Option Plan in substantially the
form that will be adopted if approved by CBC stockholders.
 
ADMINISTRATION
 
  The 1997 Option Plan will be administered by the Compensation Committee of
the CBC Board (the "Committee"). The Committee will have the power and
authority to take all actions and make all determinations required or provided
for under the 1997 Option Plan or any option issued thereunder and all such
other actions and determinations deemed by the Committee to be necessary or
appropriate for the administration of the Plan.
 
ELIGIBLE EMPLOYEES
 
  Awards of stock options under the 1997 Option Plan may be made by the
Committee to any employee or independent contractor of CBC (or any subsidiary
of CBC) identified as a key employee by CBC's Chief Executive Officer, except
that no options may be granted to any person who, at the time of the grant, is
a director or executive officer of CBC within the meaning of the Exchange Act
or who owns stock possessing more than 10 percent of the total combined voting
power of all classes of stock of CBC or any subsidiary. CBC's current
directors and executive officers are listed above under the caption "SELECTED
INFORMATION REGARDING CBC--Directors and Executive Officers."
 
OPTIONS TO BE GRANTED, PRICE AND EXERCISABILITY
 
  Nonstatutory options ("NSOs") and "incentive stock options" ("ISOs") as
defined under Section 422A of the Internal Revenue of 1986, as amended (the
"Code"), may be granted under the 1997 Option Plan. No person may be granted
in any year options to purchase more than 75,000 shares of CBC Common. The
option price for any option granted under the 1997 Option Plan will be the
closing of the CBC Common on the date of grant as reported by The Wall Street
Journal (West Coast Edition).
 
  Options granted under the 1997 Option Plan shall be exercisable at such time
and be subject to such restrictions and conditions as the Committee will in
each instance approve, which need not be the same for all option holders. Each
option that is intended to qualify as an ISO will comply with the applicable
provisions of the Code as to such stock options.
 
  With the consent of the Committee, payment of the option price may be made
through the tender to CBC of shares of CBC Common which shall be valued for
such purpose at their fair market value on the date of exercise.
 
TRANSFERABILITY
 
  The Committee may impose restrictions on any shares acquired through the
award of stock options including, without limitation, restrictions under
applicable federal and state securities laws. Options are not
 
                                      119
<PAGE>
 
assignable or transferable other than by will, by the laws of descent and
distribution, or pursuant to a qualified domestic relations order as defined
in Section 414 of the Code, and during the optionee's lifetime, any option may
be exercised only by such optionee or, in the event an optionee's legal
incapacity or incompetency, such optionee's guardian or legal representative.
 
TERMINATION OF EMPLOYMENT
 
  In the event of an optionee's death, any outstanding options then
exercisable may be exercised at any time prior to the expiration date of the
options or such earlier date as is provided for in the option agreement. In
the event of termination of an optionee's employment by reason of permanent
and total disability, any outstanding options then exercisable may be
exercised at any time prior to the expiration date of the options or within
one year after such date of termination of employment, whichever period is
shorter. On termination of employment other than due to death or disability,
the rights under any outstanding options then exercisable may be exercised for
a period of 30 days or such longer period as is specified in the option
agreement.
 
SECURITIES SUBJECT TO PLAN
 
  If option awards under the 1997 Option Plan terminate, expire or lapse, the
related shares will again be available for the grant of options.
 
CHANGES IN CAPITALIZATION
 
  In the event any change is made to the CBC Common by reason of any
recapitalization, reclassification, stock split-up, combination of shares,
exchange of shares, stock dividend or other distribution payable in capital
stock, or other increase or decrease affecting such outstanding shares
generally that is effected without receipt of consideration by CBC, occurring
after the effective date of the Plan, the number and kinds of shares available
under the Plan will be adjusted proportionately and accordingly by the
Committee. In addition, the number and kind of shares for which options are
outstanding will be adjusted proportionately and accordingly so that the
proportionate ownership interest of the holder of the option immediately
following such event will, to the extent practicable, be the same as
immediately prior to such event.
 
ACCELERATION OF VESTING
 
  In the event of the termination of the 1997 Option Plan as a result of a
Terminating Reorganization (as defined below), any holder of options under the
1997 Option Plan will have the right, during such period occurring prior to
such termination as the Committee determines, to exercise such options whether
or not such options were otherwise exercisable at the time such termination
occurred. "Terminating Reorganization" means the dissolution or liquidation of
CBC, or a merger, consolidation or reorganization of CBC with one or more
other companies in which CBC is not the surviving company, or the sale of
substantially all of the assets of CBC to another company, or any transaction
(including, without limitation, a merger or reorganization in which CBC is the
surviving company) approved by the CBC Board after February 4, 1997 which
results in any person owning 25 percent or more of the combined voting power
of all classes of stock of CBC. In the event of a Terminating Reorganization,
the 1997 Option Plan and all outstanding options thereunder will terminate
except to the extent provision is made in connection with the Terminating
Reorganization for the continuation of the 1997 Option Plan and/or the
assumption of the outstanding options or for the substitution of new options
with appropriate adjustments as to the number and kinds of shares and exercise
prices.
 
TERM AND AMENDMENT OF THE PLAN
 
  No options may be granted under the 1997 Option Plan more than ten years
after the date the 1997 Option Plan is approved by CBC's stockholders. The CBC
Board or the Committee may at any time and from time to time amend, suspend or
terminate the Plan. No such amendment may, without stockholder approval,
increase the maximum number of shares subject to the Plan, change the minimum
option price, increase the maximum period
 
                                      120
<PAGE>
 
during which options may be exercised, extend the term of the 1997 Option
Plan, materially increase the benefits to optionees or modify the Plan's
eligibility requirements.
 
FEDERAL INCOME TAX CONSEQUENCES OF OPTIONS GRANTED UNDER THE 1997 OPTION PLAN
 
  The Federal income tax treatment for ISOs and NSOs options differs as
follows:
 
  Incentive Options. No taxable income is recognized by the optionee at the
time the ISO is granted, and no taxable income is generally recognized at the
time such an option is exercised. If the optionee does not make a disposition
of the purchased shares within the two-year period following the grant date of
the option nor within the one-year period following the exercise date of the
option, any profit or loss recognized upon the subsequent disposition will be
long-term capital gain or loss. If the optionee disposes of the purchased
shares within either the two-year or one-year period mentioned above (a
"disqualifying disposition"), then the optionee will in general recognize
ordinary income in the year of disposition equal to the amount by which the
fair market value of the shares on the date the option was exercised exceeded
the exercise price (the "option spread"). Any additional gain recognized upon
such disposition will be a capital gain, which will be long-term if the shares
are held for at least one year.
 
  So long as the optionee does not make a disqualifying disposition of the
purchased shares, no business expense deduction may be taken by CBC. To the
extent that the optionee must recognize ordinary income due to a disqualifying
disposition, CBC will be allowed an income tax deduction equal to the option
spread. The deduction will in general be allowed for the taxable year of CBC
in which the ordinary income is recognized by the optionee.
 
  Nonstatutory Options. A holder of an option which is an NSO will generally
recognize ordinary income at the time the option is exercised in an amount
equal to the difference between the exercise price of the option and the
current fair market value of the shares received. CBC would normally receive
an ordinary deduction equal to that difference. However, the optionee will not
recognize income (and CBC will not receive a corresponding deduction) upon
exercise of an non-statutory option if, at that time, the option shares are
subject to a substantial risk of forfeiture and are nontransferable. Absent an
election to be currently taxed, if such forfeiture and transfer restrictions
do apply recognition of taxable income will be deferred until the forfeiture
restrictions lapse, or the shares become transferable, whichever first occurs.
In any case, upon the subsequent disposition of the option shares, the
optionee will recognize capital gain or loss in an amount equal to the
difference between the optionee's tax basis in the shares and the amount
realized upon sale. For this purpose, the optionee's tax basis will include
the option price paid by the optionee plus the amount of any ordinary income
recognized upon the exercise of the option or the lapse of forfeiture or
transfer restrictions.

          PROPOSAL TO APPROVE CBC'S 1998 EMPLOYEE STOCK PURCHASE PLAN
 
  CBC's stockholders are being asked to approve the CB Commercial Real Estate
Services Group, Inc. 1998 Employee Stock Purchase Plan (the "ESPP") which will
provide employees of CBC and its subsidiaries an opportunity to purchase CBC
Common through payroll deductions. Set forth below is a summary of the ESPP,
which is qualified in its entirety by Annex 6 to this Joint Proxy
Statement/Prospectus which sets forth the full text of the ESPP in
substantially the form that will be adopted if approved by CBC stockholders.
 
  Under the ESPP, an aggregate of 300,000 shares of CBC Common have been
reserved for issuance during the two-year period commencing January 1, 1998,
with no more than 150,000 to be issued in any calendar year (all shares under
the ESPP will be newly issued; no shares will be purchased in the market for
issuance pursuant to the ESPP). The ESPP permits the Compensation Committee of
the CBC Board to authorize the issuance of additional shares under the ESPP
after the initial two-year period, but there is no assurance the Committee
will agree to do so. Any full-time employee will be eligible to participate in
the ESPP effective as of any January 1 following the date he or she delivers
the applicable plan enrollment form to CBC. Eligible employees participate in
the ESPP by authorizing payroll deductions up to 10% of their total cash
compensation, not to exceed $25,000 per year. At the end of each one-year
offering period, the first of which will commence January 1, 1998, CBC will
apply the amount contributed by the participant during the offering period to
purchase whole shares of CBC Common. Shares of CBC Common are purchased at the
lower of (i) the market price of CBC Common at the beginning of the applicable
offering period or (ii) the market price of such CBC Common at the end of the
applicable offering period (market price is the closing price of CBC Common on
the applicable date). Certificates for such shares will be sent to
participants as soon as reasonably practicable after the end of the applicable
offering period. To the extent the number of shares of CBC Common that could
be purchased with the aggregate contributions made by participants in any year
exceeds the number of shares available for that year, the shares will be
allocated to participants pro rata based on the amount of their contributions
and any contributions not applied to purchase shares will be returned to
participants with interest at 5% after the end of the applicable offering
period (interest will not otherwise be credited under the ESPP). All expenses
incurred in connection with the implementation and administration of the ESPP
will be paid CBC.

CBC BOARD RECOMMENDATION
 
  THE CBC BOARD RECOMMENDS A VOTE IN FAVOR OF THIS PROPOSAL.
 
       PROPOSAL TO AMEND CBC'S 1991 SERVICE PROVIDERS STOCK OPTION PLAN
 
  At the CBC Meeting, CBC stockholders are also being asked to approve an
amendment to CBC's 1991 Service Providers Stock Option Plan (the "1991 Plan"),
which was approved by the stockholders of CBC in 1991 and authorizes the
issuance of stock options with respect to 700,000 shares of CBC Common. The
text of the amendment is attached as Annex 7 to this Joint Proxy
Statement/Prospectus. The amendment is intended to make it clear that options
may be granted either at fair market value or, when an employee or independent
contractor has given up the right to receive cash compensation (salary, bonus,
directors fees, etc.), at an appropriate discount. The text of the 1991 Plan
permits grants either at fair market value or at a discount, but the
description of the 1991 Plan in the proxy statement which requested approval
of the Plan by CBC Stockholders indicated that the "primary" purpose of the
Plan was to grant discounted options, thus implying that more than half of all
of the shares reserved under the 1991 Plan should be granted on a discounted
basis. If the amendment is approved, the Compensation Committee of the CBC
Board would be able to grant whatever options it thinks
 
                                      122
<PAGE>
 
appropriate, whether at fair market value or at an appropriate discount when
someone agrees to forgo cash compensation. To date, the Compensation Committee
has granted options for a total of 270,713 shares of CBC Common, 30,000 to
three directors at fair market value, 40,713 to various directors and
consultants at a discount in exchange for giving up cash compensation and
200,000 to Chairman and Chief Executive Officer James J. Didion at fair market
value. If the CBC Stockholders do not approve the amendment to the 1991 Plan,
no further fair market grants will be made pursuant to that plan.

  A VOTE OF A MAJORITY OF THE OUTSTANDING VOTES ENTITLED TO BE CAST BY THE
HOLDERS OF CBC'S A-1 PREFERRED, A-2 PREFERRED AND COMMON STOCK, VOTING

CBC BOARD RECOMMENDATION
 
  THE CBC BOARD RECOMMENDS A VOTE IN FAVOR OF THIS PROPOSAL.
 
             PROPOSAL TO APPROVE CBC'S 1996 EQUITY INCENTIVE PLAN
 
GENERAL
 
  At the CBC Meeting, CBC stockholders will be asked to approve CBC's 1996
Equity Incentive Plan (the "EIP") which permits CBC to grant eligible
employees the right to purchase up to 550,000 shares of CBC Common Stock. Set
forth below is a summary of the EIP which is qualified in its entirety by
Annex 8 to this Joint Proxy Statement/Prospectus which sets forth the full
text of the EIP.
 
  The EIP was adopted by the Board of Directors in November of 1995 and grants
to purchase 510,906 shares of CBC Common Stock were made to eight eligible
employees in February of 1996. These employees were permitted to pay the
entire purchase price (other than the par value of the shares) by delivery of
a full recourse promissory note because CBC was not at that time subject to
the margin rules of Federal Reserve Board Regulation G which restricts credit
extensions with respect to traded stock to 50% of its value. On April 1, 1997
the Compensation Committee granted new Chief Financial Officer John Haeckel
the right to purchase 35,000 shares of common stock under the EIP and to pay
the purchase price in excess of par value by delivery of a full recourse
promissory note. Under Regulation G this will be an impermissible extension of
credit unless the EIP is approved by the CBC stockholders.
 
ADMINISTRATION
 
  The EIP is administered by the Compensation Committee of the CBC Board. The
Committee has the power and authority to take all actions and make all
determinations required or provided for under the EIP and all such other
actions and determinations deemed by the Committee to be necessary or
appropriate for the administration of the Plan.
 
ELIGIBLE EMPLOYEES
 
  Only the Chief Executive Officers, Presidents and Senior Executive Vice
Presidents of CBC and its subsidiaries (plus other key management personnel
designated by the Chief Executive Officer) are eligible to receive grants
under the EIP.
 
                                      123
<PAGE>
 
SHARES TO BE ISSUED, PRICE, PAYMENT AND VESTING
 
  A total of 550,000 shares of CBC Common have been reserved for issuance
under the EIP. The shares may be issued to senior executives for a purchase
price equal to the greater of $10.00 per share or fair market value. The
purchase price for shares under this plan must be paid either in cash or by
delivery of a full recourse promissory note. Any shares purchased vest at the
rate of 5% per quarter. In the event a participant's employment is terminated
without cause within 12 months after a change in control he or she will vest
in 50% of the original number of shares awarded (or, if less, the then
unvested shares). Any shares which are not vested at the time an employee's
employment terminates may be repurchased by the Company for the lesser of the
original purchase price or their fair market value. Any repurchased shares are
available for regrant under the EIP.
 
SHARES GRANTED
 
  In January 1996, the Compensation Committee awarded ten senior executives a
total of approximately 540,000 shares under the EIP, subject to the authority
of Chief Executive Officer to reduce any grants. After reductions a total of
510,906 shares were purchased. The following amounts of shares were purchased
by the individuals named in the Summary Compensation Table above: James J.
Didion--175,027; Gary J. Beban--53,910; Richard C. Clotfelter--33,750; George
J. Kallis--42,750; Richard A. Pogue--35,750; Kenneth D. Sandstad--44,586;
Walter V. Stafford--70,750 and John L. Stanfill--54,383. The shares previously
acquired were purchased at $10.00 per share. On April 1, 1997 John Haeckel was
granted the right to purchase 35,000 shares of Common Stock for $23.50 per
share.

          PROPOSAL FOR RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS
 
  The CBC Board has appointed the firm of Arthur Andersen LLP, Certified
Public Accountants ("AA"), who audited CBC's consolidated financial statements
for calendar year 1996, as independent accountants to audit the consolidated

presented to the stockholders for ratification at this meeting. If the
stockholders do not ratify the employment of AA, the selection of independent
accountants will be reconsidered by the CBC Board. Representatives from the
firm of AA will be present at the CBC Meeting. They will be provided the
opportunity to make a statement if they desire to do so, and will be available
to respond to appropriate questions.
 
                                 OTHER MATTERS

                        REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors
Koll Real Estate Services
 
  We have audited the accompanying consolidated balance sheets of Koll Real
Estate Services (the "Company") as of December 31, 1996 and March 31, 1996,
and the related consolidated statements of operations, stockholders' equity
and cash flows for the nine months ended December 31, 1996, the year ended
March 31, 1996 and the four months ended March 31, 1995. We also have audited
the accompanying consolidated statements of operations, stockholders' equity
and cash flows of Koll Management Services, Inc. (the "Predecessor Company")
for the eight months ended November 30, 1994. These financial statements are
the responsibility of the Companies' management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Koll Real Estate Services at December 31, 1996 and March 31, 1996, and the
consolidated results of its operations and its cash flows for the nine months
ended December 31, 1996, the year ended March 31, 1996 and the four months
ended March 31, 1995, and the consolidated results of operations and cash
flows of Koll Management Services, Inc. for the eight months ended November
30, 1994, in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1996
  (INFORMATION FOR THREE-MONTH PERIODS ENDED MARCH 31, 1997 AND 1996 AND THE
           NINE MONTH PERIOD ENDED DECEMBER 31, 1995 IS UNAUDITED.)
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION
 
  Koll Real Estate Services ("Koll" or the "Company," formerly KMS Holding
Corporation), a Delaware corporation, was organized to acquire Koll Management
Services, Inc. ("KMS" or the "Predecessor Company") in November 1994. KMS was
incorporated in California in June 1988 and reincorporated in Delaware in May
1991.
 
  KMS was a wholly-owned subsidiary of The Koll Company ("TKC") until July 31,
1991, when it completed an initial public offering of common stock. On
November 23, 1994, Koll acquired 100% of the outstanding common stock of KMS
pursuant to a merger agreement (the "Merger"). In connection with the Merger,
TKC transferred all of its stock in KMS to The Koll Holding Company ("KHC"),
of which 1,576,000 shares of common stock (representing 50% of the outstanding
stock of KMS) were contributed to Koll for a 48% interest. Koll accounted for
the acquisition of these shares at KHC's predecessor cost, or $7,356,000. Koll
then acquired the remaining 50% of KMS' common stock for $25,224,000 ($16 per
share), of which 36% was acquired from KMS' public shareholders and the
remaining 14% interest was acquired from KHC. KMS subsequently agreed to pay
the public shareholders an additional $0.50 per share, which totaled an
additional $569,000. The aggregate purchase price, including direct
transaction costs of $366,000, was $33,515,000.
 
  The Merger resulted in $18,955,000 of purchase price in excess of the
estimated fair value of the net assets acquired. This amount, net of
subsequent amortization, is included in goodwill in the accompanying
consolidated balance sheets. Transaction costs associated with the Merger and
incurred by KMS totaled $817,000 and were expensed.
 
  The accompanying consolidated financial statements present the Merger as if
it had occurred after the close of business on November 30, 1994, the
designated effective date of the transaction for accounting purposes.
 
  The accompanying consolidated statements of operations, stockholders'
equity, and cash flows for the eight months ended November 30, 1994 present
the consolidated results of the Predecessor Company's operations and its cash
flows prior to the Merger. The consolidated results of the Company's
operations and its cash flows for the nine months ended December 31, 1996, the
year ended March 31, 1996 and the four months ended March 31, 1995 reflect the
results of the Merger and, as a result, are not comparable to the financial
position, results of operations and cash flows of the Predecessor Company in
periods prior to the Merger.
 
  Effective December 31, 1996, the Company changed its fiscal year to end on
December 31 from the previous fiscal year ending on March 31. Accordingly, the
Company's results of operations and its cash flows for the transition period
ended December 31, 1996 are for a nine month period.
 
BUSINESS
 
  The Company provides real estate management and advisory services throughout
the United States and in certain portions of Asia. The services provided
include property management, asset management, facility management, commercial
brokerage, asset disposition, institutional investment and pension fund
advisory and construction management services. A portion of the Company's
business is conducted with affiliates of TKC (Note 11).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
INTERIM FINANCIAL INFORMATION
 
  The accompanying unaudited consolidated financial statements as of March 31,
1997 and for the three months ended March 31, 1997 and 1996 and the nine
months ended December 31, 1995, have been prepared in accordance with
generally accepted accounting principles and the requirements of Regulation S-
X for interim financial information. Accordingly, they do not include all of
the information required by generally accepted accounting principles for
complete financial statements. In the opinion of management, all adjustments,
consisting of normal recurring accruals, considered necessary for a fair
presentation, have been included. Operating results for the three months ended
March 31, 1997 are not necessarily indicative of the results that may be
expected for the year ending December 31, 1997. The Company provides for
income taxes during interim periods based on the estimated annual effective
tax rate.
 
CONSOLIDATION
 
  The accompanying consolidated financial statements include the accounts of
the Company and its subsidiaries and partnerships in which it has controlling
interests. Results of operations of acquired entities are recognized
commencing on the effective date of each entity's acquisition. All significant
intercompany transactions have been eliminated in consolidation.
 
ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities as of
December 31, 1996 and March 31, 1996, and revenue and expenses for the periods
presented. Actual results could differ from those estimates.
 
  Significant estimates made in preparing the consolidated financial
statements include allowances for doubtful accounts, amounts used in
evaluating the recoverability of investments, advances and intangible assets,
as well as the amortization lives used for the Company's intangible assets.
 
CASH EQUIVALENTS
 
  Cash equivalents consist of short-term, highly-liquid investments with
maturities of 90 days or less when purchased.
 
CASH HELD IN TRUST AND TRUST ACCOUNT LIABILITY
 
  Cash held in trust consists principally of gross proceeds from auctions
collected on behalf of the selling parties which is held in a trust account
until the final settlement date of the auction. Such amounts held at year-end
are shown as cash held in trust in the accompanying consolidated balance
sheets. Cash held in trust is excluded from cash and cash equivalents for
purposes of the consolidated statements of cash flows.
 
  The trust account liability represents the portion of cash proceeds and
credit card receivables, which are included in accounts receivable, that must
be remitted to the selling parties.
 
FAIR VALUES OF FINANCIAL INSTRUMENTS
 
  Fair values of cash and cash equivalents and the current portion of long-
term debt approximate the carrying value because of the short period of time
to maturity. The fair value of long-term debt approximates its carrying value
because the fixed rates of interest on a portion of the debt approximate
current market rates and the remaining portion of the debt has variable rates
of interest.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
PREPAID EXPENSES AND OTHER CURRENT ASSETS
 
  Prepaid expenses and other current assets consist primarily of prepaid
insurance, various deposits and miscellaneous receivables.
 
FURNITURE, FIXTURES AND EQUIPMENT
 
  Furniture, fixtures and equipment are stated at cost (Note 3). Depreciation
is computed using the straight-line method over estimated useful lives ranging
from three to seven years.
 
INVESTMENTS AND ADVANCES
 
  Investments consist principally of noncontrolling interests in service and
real estate entities. The Company accounts for investments in which it has
significant influence (generally 20% to 50% interests) using the equity method
of accounting. Under the equity method, the Company includes its share of the
income or losses of such entities in its operating results. The Company
records its share of the income or losses of certain entities 90 days in
arrears. The Company accounts for entities in which it does not have
significant influence (generally under 20% interests) using the cost method.
 
COVENANTS NOT TO COMPETE
 
  Costs related to covenants not to compete are amortized on a straight-line
basis over the periods benefited, ranging from five to ten years. Payments for
covenants not to compete that are contingent based upon future events are
capitalized when the contingency is resolved and amortized over the remaining
period benefited. Accumulated amortization totaled $636,000 and $415,000 at
December 31, 1996 and March 31, 1996, respectively.
 
MANAGEMENT AGREEMENTS
 
  Management agreements include direct costs paid for such agreements to
unaffiliated management companies and costs allocated to management
agreements, based upon their estimated fair value, in connection with the
Merger (Note 1--Organization) and acquisitions of the stock or assets of other
companies (Note 2). The management agreements typically contain evergreen
provisions which provide that the agreements remain in effect for an
indefinite period but generally enable the property owner and the Company to
terminate the agreement upon thirty days prior written notice.
 
  The cost associated with each "pool" of management agreements is amortized
on a straight-line basis over the estimated periods benefited, ranging from
two to ten years. The estimated period benefited is established based upon
management's assessment of the risk associated with retaining the individual
agreements within each pool. The "attrition" factors considered include the
relationships with the owners of the underlying properties, the extent to
which the Company retains the senior management that had historically managed
the properties, and the cash flow of the properties. Accumulated amortization
totaled $6,146,000 and $3,754,000 at December 31, 1996 and March 31, 1996,
respectively.
 
  When indicators of impairment of a pool of management agreements are
present, management evaluates for impairment and reviews the reasonableness of
the remaining amortization period by comparing the projected cash flow of each
pool of management agreements, on an undiscounted basis, over the remaining
amortization period of the pool to the remaining unamortized cost of the pool.
If the projected undiscounted cash flow of any pool is less than the 
unamortized cost of the pool, then the recorded cost of the pool would be 
written down to

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
an amount equal to its estimated fair value. Estimated fair value would be
determined by discounting future cash flows at an appropriate discount rate.
 
  Projected cash flow for each pool of management agreements represents
estimates, based on present plans and intentions, of management fees and other
revenue less direct costs. The estimation process involved in the
determination of projected cash flow is inherently uncertain since it requires
estimates as to future events and conditions. Such future events and
conditions include economic, political and market conditions, as well as the
availability of suitable financing to fund development and construction
activities, and the repayments or refinancing of existing indebtedness. Such
economic, political, market and financing conditions may affect occupancy
rates of the managed properties. As the amount and timing of the fees to be
earned under such contracts is dependent upon such future uncertain events and
conditions, the ultimate realization may be materially different in the near
term from amounts presently estimated in determining projected cash flow.
 
GOODWILL
 
  Goodwill related to the Merger (Note 1--Organization), as well as
acquisitions of unrelated companies, is amortized over the estimated periods
benefited. Goodwill resulting from the Merger amounted to $18,955,000 and is
being amortized over 30 years. Goodwill resulting from other acquisitions is
being amortized over a range of 5 to 30 years. Accumulated amortization of
goodwill amounted to $3,066,000 and $1,755,000 at December 31, 1996 and March
31, 1996, respectively.
 
OTHER ASSETS
 
  Other assets includes costs incurred by the Company to organize and
structure investment funds in which the Company holds general partnership
interests and for which the Company performs investment management and
advisory services. Such costs are amortized using the straight-line method
over the estimated period benefited of five years. Other assets also includes
organization and deferred financing costs incurred in connection with the
Merger. Organization costs are being amortized on a straight-line basis over
five years. Deferred financing costs are being amortized on a straight-line
basis over the term of the related loan agreements. Accumulated amortization
totaled $4,069,000 and $2,506,000 at December 31, 1996 and March 31, 1996,
respectively. Other assets also includes certain long-term fees receivable,
net of allowances of $496,000 and $541,000 at December 31, 1996 and March 31,
1996, respectively.
 
REVENUE
 
  Revenue consists primarily of management fees, certain onsite
reimbursements, leasing commissions, investment sales commissions and auction
fees. Base fee revenue (management fees and onsite reimbursements) is
recognized as the services are rendered. Transaction fee revenue (such as
leasing commissions, asset acquisition and disposition fees) is recognized
when earned, generally upon the closing of the related transaction.
 
ADVERTISING EXPENSE
 
  The cost of advertising is expensed as incurred. The Company and the
Predecessor Company incurred $483,000, $622,000, $450,000 and $229,000 in
advertising costs during the nine months ended December 31, 1996, the year
ended March 31, 1996, the four months ended March 31, 1995, and the eight
months ended November 30, 1994, respectively.

STOCK OPTIONS
 
  The Company follows Accounting Principles Board Opinion No. 25, Accounting
for Stock Issued to Employees ("APB No. 25"), and related interpretations in
accounting for employee stock options. Effective April 1, 1996, the Company
adopted Statement of Financial Accounting Standards No. 123, Accounting for
Stock-Based Compensation ("SFAS No. 123"). SFAS No. 123 encourages, but does
not require, companies to record compensation cost for stock-based employee
compensation plans at fair value. The Company has adopted the disclosure-only
provisions of FASB 123 and has chosen to continue to account for stock-based
compensation using the intrinsic value method prescribed in APB Opinion No. 25
and related interpretations. Accordingly, compensation cost for stock options
is measured as the excess, if any, of the quoted market price of the Company's
stock at the measurement date over the amount an employee must pay to acquire
the stock.
 
INCOME TAXES
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes ("SFAS No.
109"). Under SFAS No. 109, the liability method is used, whereby, deferred tax
assets and liabilities are determined based on differences between financial
reporting and tax bases of the assets and liabilities and are measured using
enacted tax rates and laws that will be in effect when the differences are
expected to reverse.
 
  Since the effective date of the Merger, KMS' operating results are included
in the consolidated tax return of the Company for federal and certain state
income tax purposes. Prior to the Merger, in certain states, KMS had filed
combined state tax returns with TKC and tax expense had been apportioned based
on a tax sharing agreement.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
  In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to be Disposed of ("SFAS No. 121"). In
accordance with SFAS No. 121, long-lived assets and certain intangibles held
and used by the Company are reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. The recoverability test is performed at the lowest level at which
undiscounted net cash flows can be directly attributable to long-lived assets.
When indicators of impairment are present and projected future undiscounted
cash flows are less than the carrying amount of the asset, then the asset
would be written down to its estimated fair value. The Company adopted SFAS
No. 121 effective April 1, 1996 and there was no effect on its financial
position, results of operations or liquidity.
 
PER SHARE DATA
 
  Earnings per share is computed using the weighted average number of shares
of common stock and dilutive common stock equivalents outstanding during the
year. Common equivalent shares relating to stock options are computed using
the treasury stock method. When the Company is in a loss position for a
particular reporting period, the effect of outstanding stock options is
excluded since it is anti-dilutive.
 
  In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings per Share, which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method
currently used to compute earnings per share and to restate all prior periods.
Under the new requirements for calculating primary earnings per share, the
dilutive effect of stock options will be excluded. The impact of Statement 128
on the calculation of earnings per share is not expected to be material.

2. ACQUISITIONS
 
  Effective January 1, 1995, the Company purchased the stock of CBS Investment
Realty, Inc. and CBS Investment Realty of New Mexico, Inc., property
management and brokerage companies with headquarters in Phoenix, Arizona
("CBS"). The Company also purchased the business and assets of affiliated
companies with property management and brokerage operations in Texas and
California. The combined purchase price consisted of two promissory notes
secured by letters of credit. One note was due and paid in January 1996. The
second note bears interest at 9% per annum, payable quarterly, with principal
installments due in April 1996 (which was paid), 1997, 1998 and 1999. The
purchase price in excess of the estimated fair value of net assets acquired
totaled $7,068,000 and is included, net of amortization, in goodwill in the
December 31, 1996 and March 31, 1996 consolidated balance sheets. In May 1996,
the Company executed an amendment to the CBS purchase agreement which provided
for the buyout of the earnout portion of the purchase price. The buyout
consists of four equal installments due May 1996 (which was paid), 1997, 1998
and 1999 and releases the Company from any further obligation to the former
owners.
 
  In March 1995, the Company formed Koll-Dove Global Disposition Services,
L.L.C. ("Koll-Dove"), a limited liability company engaged in asset disposition
services. The Company has a 50.1% controlling interest in Koll-Dove, and the
other 49.9% is owned by parties related to and including The Dove Holdings
Corporation (formerly The Ross-Dove Company, Inc.) (collectively, "Dove
Group"), an asset disposition company based in Northern California. The
Company contributed cash at closing plus a promissory note which was paid in
full by March 31, 1996. Dove Group contributed substantially all of its non-
real estate assets and related liabilities, excluding receivables from its
shareholders. This transaction has been accounted for as a purchase. The
contribution by the Company of $5,000,000 in cash and notes exceeded the
proportionate book value of net assets (liabilities) acquired by $5.1 million.
This excess is included, net of amortization, in goodwill in the accompanying
consolidated balance sheets.
 
  In April 1995, the Company acquired a real estate market research and
publishing operation from Liquidity Financial Group, L.P. by purchasing
certain assets, including publishing rights, contracts, trademarks and
research information. The purchase price included a payment which was made in
April 1995, plus an additional amount which is subject to downward adjustment
based on earnings through May 2001. In August 1996, the Company executed an
amendment to the purchase agreement which provided for the buyout of the
earnout portion of the purchase price. The buyout consists of one fixed
installment due in March 1998. The purchase price in excess of the estimated
fair value of net assets acquired totaled $2,147,000 and is included, net of
amortization, in goodwill in the accompanying consolidated balance sheets.
 
  In July 1995, the Company acquired certain businesses and assets of two
affiliated Minneapolis-based companies, The Shelard Group, Inc. and SCI
Services, Inc. (collectively "Shelard"). Shelard provides property and
facility management services, commercial real estate brokerage services and
general contractor and construction services in Minneapolis and St. Paul. The
purchase price consisted of cash at closing and a portion of net operating
income (as defined) above a specified amount, over a four-year period. The
Company also entered into employment and noncompetition agreements with
certain Shelard shareholders.
 
  These transactions have been accounted for as purchase business acquisitions
and, accordingly, the results of operations of the acquired entities have been
included in the Company's consolidated results of operations from the
respective dates of acquisition.

$1,000,000 and $500,000, respectively, due on demand) that are netted with the
investment balances. The remaining notes, totaling $2,330,000 and $1,000,000
at December 31, 1996 and March 31, 1996, respectively, are recourse and are
included in other long-term obligations. The notes accrue interest at the
long-term applicable federal rate circulated by the Internal Revenue Service
(6.77% at December 31, 1996). The notes (including demand notes) mature upon
the earlier of dates ranging from December 2005 to December 2006, or the
termination of the respective investee partnerships. Principal and interest
payments are to be made as distributions are received from the investee
partnerships.
 
  As of December 31, 1996, certain subsidiaries are obligated to contribute
additional nonrecourse capital notes to the investee partnerships in an
aggregate amount of approximately $500,000.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
5. NOTES PAYABLE TO BANKS
 
  As of December 31, 1996, the Company had a $63,675,000 line of credit
($48,675,000 at March 31, 1996) for acquisition ($35,675,000) and working
capital ($28,000,000) purposes which was due to expire on December 31, 1999.
At December 31, 1996, borrowings under the line of credit are secured by the
common stock of KMS and its subsidiaries, and the maintenance of certain
financial ratios is required. A commitment fee ranging from .25% to .50% per
annum of the line amount and a letter of credit fee, ranging from 0.625% to
2.25% per annum of the letter of credit amount, depending upon KMS' leverage
ratio, is required. Borrowings bear interest at either (i) prime plus a
margin, ranging from 0% to 1.25% or (ii) adjusted Eurodollar rate plus a
margin, ranging from 0.625% to 2.25%. The margins adjust depending upon KMS'
leverage ratio, as specified in the credit agreement. At December 31, 1996,
the interest rates ranged from 7.9375% to 9.5% and $46,887,500 was outstanding
under the credit line, consisting of $22,963,814 on the acquisition line and
$23,923,686 on the working capital revolver. At March 31, 1996, $42,025,000
was outstanding under the line of credit. In addition, $3,562,500 has been set
aside on the acquisition line as collateral for a $3,562,500 letter of credit
related to an acquisition that closed in fiscal 1995 and will be drawn as
payments are due on the underlying note. Accordingly, at December 31, 1996,
the Company had $9,148,686 of availability under the acquisition line and
$4,076,314 of availability on the working capital revolver. The above line of
credit was replaced with an amended and restated credit agreement subsequent
to December 31, 1996 (Note 16).
 
  Management believes the Company was in compliance with all covenants under
the credit agreement. The covenants restrict KMS from distributing funds to
Koll, except to enable Koll to pay certain administrative expenses and to
repurchase, pursuant to the terms of certain subscription agreements, Company
common stock from management (Note 7). At December 31, 1996, retained earnings
subject to these restrictions totaled $2,024,000.
 
  Koll-Dove has a revolving line of credit that is secured by Koll-Dove's
proceeds on auctions and bears interest at prime plus 2% (10.25% at December
31, 1996). All outstanding principal plus accrued and unpaid interest were due
on demand or, if no demand is made, on April 15, 1997. The Company is in the
process of negotiating an extension of the credit lines. At December 31, 1996
and March 31, 1996, Koll-Dove had $350,000 and $314,000, respectively,
outstanding under the line of credit. At December 31, 1996, Koll-Dove had
$150,000 available to draw on the credit line and has a $1,000,000 letter of
credit facility available through April 15, 1997.
 
  Koll-Dove also has a short-term loan agreement with a bank for $4,000,000,
secured by a $4,000,000 certificate of deposit and all of Koll-Dove's accounts
receivable. The loan bears interest at prime plus 2% (10.25% at December 31,
1996). All outstanding principal plus accrued and unpaid interest are due on
demand or, if no demand is made, on January 7, 1997. The note was paid in full
in January 1997.

10. COMMON STOCK AND STOCK AWARD PLANS
 
  During the four months ended March 31, 1995, the Company adopted the Koll
Real Estate Services 1994 Nonqualified Performance Stock Option Plan, as
amended (the "Performance Option Plan"), under which officers, certain
directors, key employees and consultants of the Company and its subsidiaries
are eligible to be granted options to purchase common stock of the Company.
Through March 31, 1996 the Company's Board of Directors had set aside 515,000
shares of common stock to be issued pursuant to the Performance Option Plan,
which is being administered by a committee established by the Company's Board
of Directors. The vesting of options under the plan may be based on the
Company's attainment of performance criteria specified at the time options are
granted and may also be based on the passage of time. The percentage of the
options granted through March 31, 1996 that would vest, if any, was to be
determined based on adjusted cumulative earnings, as defined, during the five
fiscal years ended March 31, 1999. At March 31, 1996, no compensation expense
was accrued

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
related to outstanding options under the Performance Option Plan since
achievement of the minimum specified performance criteria was not yet deemed
probable.
 
  On April 1, 1996, the Company's Board of Directors increased the number of
shares set aside under the Performance Option Plan to 590,000 shares of common
stock and granted an option to a director to purchase 75,000 shares of common
stock at $14 per share. In addition, effective April 1, 1996, the Company
modified the option agreements for all outstanding options to include a five-
year fixed vesting period commencing April 1, 1996, with accelerated vesting
based on the achievement of earnings goals for the three years ending
March 31, 1999. This modification resulted in a new measurement date under
generally accepted accounting principles. Accordingly, non-cash compensation
expense of $1,824,000 is being recognized over the vesting period, including
$329,000 which was recognized during the nine months ended December 31, 1996.
 
  The following table summarizes activity under the Performance Option Plan
through December 31, 1996:

  The Company has adopted the disclosure-only provisions of FASB 123.
Accordingly, compensation expense has not been recognized for the stock option
plan based on the fair value at the grant date for awards in 1996 and 1995.
The pro forma effects of using the fair value method to recognize compensation
expense are not material to the Company's financial statements.
 
  The fair value of each option grant is estimated on the date of grant using
the minimum value option-pricing model with the following weighted-average
assumptions used for grants in the nine months ended December 31, 1996 and the
year ended March 31, 1996, respectively: a risk-free interest rate of 6.6% and
6.1%, respectively; no dividend yield; and an expected life of 7.5 years. The
weighted-average remaining contractual life of options at December 31, 1996 is
approximately 8 years. The weighted-average fair value as of the grant date
for options granted in the nine months ended December 31, 1996 and the year
ended March 31, 1996 was $5.53 and $3.92, respectively. The exercise prices of
options outstanding at December 31, 1996 ranged from $10.00 to $14.00.
 
  In May 1991, the Predecessor Company's Board of Directors adopted the Koll
Management Services, Inc. 1991 Stock Award Plan (the "Stock Award Plan"). The
Predecessor Company set aside 330,000 shares of its common stock to be issued
pursuant to the Stock Award Plan. The Stock Award Plan was administered by the
Compensation Committee appointed by the Predecessor Company's Board of
Directors and provided for the

11. RELATED PARTY TRANSACTIONS
 
  The Company and KMS have provided services to affiliates of the Company.
Such services include property and asset management, information, personnel,
human resource and various other services. Total revenue earned for providing
such services to affiliates was $13,666,000, $15,238,000, $4,029,000 and
$5,971,000 for the nine months ended December 31, 1996, the year ended March
31, 1996, the four months ended March 31, 1995, and the eight months ended
November 30, 1994, respectively.
 
  Under a management agreement with TKC, the Company and KMS were provided
executive management services by certain key personnel primarily employed by
TKC. KMS compensated TKC for those services based on an annual estimate of the
time spent by such personnel on business of the Company and its subsidiaries.
During the year ended March 31, 1996, the four months ended March 31, 1995,
and the eight months ended November 30, 1994, TKC billed $281,000, $87,000 and
$189,000, respectively, for such executive management services. On April 1,
1996, this agreement was terminated and certain TKC executives became
employees of KMS.
 
  The Company and KMS also pay costs of the health insurance benefits for TKC
and its affiliates and bills TKC and each affiliate monthly in amounts
approximating their pro-rata portion (based on employee head count) of the
premium obligations. The total billings for such health insurance benefits for
the nine months ended December 31, 1996, the year ended March 31, 1996, the
four months ended March 31, 1995, and the eight months ended November 30, 1994
were $1,545,000, $1,721,000, $426,000 and $736,000, respectively. These
billings are netted in cost of fee based services and administrative expenses
in the accompanying consolidated statements of income.
 
  The Company and KMS paid consulting fees totaling $263,000, $350,000,
$117,000 and $233,000 during the nine months ended December 31, 1996, the year
ended March 31, 1996, the four months ended March 31, 1995, and the eight
months ended November 30, 1994, respectively, to an investment advisor who was
a director of KMS and is an officer of one of its wholly-owned subsidiaries.
This individual is also a partner in a number of the Company's consolidated
investee partnerships and received distributions from such partnerships
totaling $1,824,000, $900,000, $235,000 and $65,000, respectively, for the
nine months ended December 31, 1996, the year ended March 31, 1996, the four
months ended March 31, 1995, and the eight months ended November 30, 1994.

  As of December 31, 1996 and March 31, 1996, KMS had loaned an aggregate of
approximately $710,000 and $640,000, respectively, to a customer partnership
which includes as partners TKC and certain current and former officers and
employees of either TKC or KMS.
 
  Three officers of KMS participate in the earnings of K/B Investors I and K/B
Opportunity Investors, both of which are 50.1% owned and consolidated
partnerships. The officers' aggregate participation interests are 12.4% and
13%, respectively. The amounts accrued for such payments at December 31, 1996
and March 31, 1996 were $5,000 and $98,000, respectively. The aggregate
amounts paid under the participation agreement were $485,000, $592,000 and
$62,000, respectively, during the nine months ended December 31, 1996, the
year ended March 31, 1996 and the eight months ended November 30, 1994. No
amounts were paid during the four months ended March 31, 1995.
 
  Payments by KMS to TKC for state income taxes totaled $220,000 during the
eight months ended November 30, 1994. No payments were made to TKC for income
taxes for the nine months ended December 31, 1996, the year ended March 31,
1996 or the four months ended March 31, 1995.
 
12. EMPLOYEE BENEFIT PLANS
 
  The Company's employees may participate, subject to eligibility, in TKC's
401(k) Plus Employee Savings Plan (the "401(k) Plan"). Employees are eligible
to participate in the 401(k) Plan after 60 days of service and, at the
Company's discretion, a portion of employee contributions may be matched by
the Company at a rate up to 50%. No matching contributions were made by the
Company or KMS during any of the periods presented.
 
13. COMMITMENTS AND CONTINGENCIES
 
  The Company is the guarantor of TKC's obligations under an operating lease
for the Company's headquarters that requires minimum monthly payments of
approximately $111,000 through August 31, 2007. The Company, as the primary
occupant of the building, currently pays monthly rent to TKC of approximately
$75,000.
 
  The Company is a defendant in various lawsuits and, based upon the advice of
legal counsel, management believes that the outcome of such actions will not
have a material effect on the Company's consolidated financial position,
results of operations or liquidity.
 
14. INDUSTRY SEGMENTS
 
  The Company operates primarily in two business segments: (1) Property and
Corporate Services, and (2) Investment Management. The Property and Corporate
Services segment provides services including property management, leasing and
marketing, general contracting and construction management, capital asset
disposition and acquisition and other real estate management services. The
Investment Management segment provides investment management services,
including property acquisition, disposition, financing and valuation
consulting and general partner management services for real estate limited
partnerships throughout the United States.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Identifiable assets by industry segment are those assets used in the Company
and subsidiaries' operations in each industry segment. Identifiable assets and
revenues of foreign operations are not material to the consolidated financial
statements. Corporate assets are principally made up of deferred taxes,
general prepaids, capitalized acquisition costs and deferred financing costs.
   
  The Company has a 30% interest in Koll Telecommunication Services, L.L.C.
("KTS"), whose operations are in the United States and Canada and are
vertically integrated with the Company's Property and Corporate Services
segment. The Company's equity in KTS' net income (loss) totaled $912,000,
($585,000), ($128,000) and ($48,000) during the nine months ended December 31,
1996, the year ended March 31, 1996, the four months ended March 31, 1995 and
the eight months ended November 30, 1994. The Company's investment in KTS' net

1996, March 31, 1996 and 1995 and November 30, 1994, respectively.     
 
  The Company had 40% interests in Insignia CCP III Acquisition, L.L.C. and
Insignia CCP IV Acquisition L.L.C. Each of these L.L.C.s hold limited
partnership interests in limited partnerships that own real estate throughout
the United States. These operations are not vertically integrated into any of
the Company's reported segments. The Company sold its interests in these
entities during the nine months ended December 31, 1996 (Note 4).
 
  The Company and KMS have provided services to customers in diversified
industries, and no single customer represented more than 10% of total revenue
in any period presented in the accompanying consolidated financial statements.
The percentage of the Company and its subsidiaries' total revenue to customers
in the insurance industry was approximately 15% during the nine months ended
December 31, 1996 and 22% during the year ended March 31, 1996.
 
  The Company performs periodic credit evaluations of its customers' financial
condition and generally does not require collateral. Credit losses have been
within management's expectations and within amounts provided through the
allowance for doubtful accounts. At December 31, 1996, accounts receivable
from customers in the insurance industry were $3,370,000.

16. SUBSEQUENT EVENTS
 
  On January 9, 1997, the Company received a $25,000,000 equity infusion from
certain existing shareholders and entered into an amended and restated credit
agreement. The amended credit agreement increased the total borrowing
availability and revised the components to consist of a $25,000,000 term loan
and a $70,000,000 revolving facility ($45,000,000 for acquisitions and
$25,000,000 for working capital). Unamortized deferred loan fees aggregating
$1.2 million related to the pre-amendment credit facility were charged to
expense in the quarter ended March 31, 1997. The new credit agreement matures
on September 30, 2001 and periodic principal reductions are required beginning
March 31, 1998. The fees and interest rate margins, which are more fully
discussed in Note 5, were adjusted to the following ranges:

  On March 18, 1997, shareholders representing a majority of the Company's
outstanding shares entered into a letter of intent agreement whereby the
Company would be merged with and into a subsidiary of CB Commercial Real
Estate Services Group, Inc.
 
  Subsequent to December 31, 1996, the Company began the process of
negotiating the buyout of a minority interest in one of its consolidated
subsidiaries for a purchase price of approximately $5,250,000.

To the Board of Directors
Koll Real Estate Services
 
  We have audited the combined statement of operations of the Business
Acquired from The Shelard Group, Inc. and Affiliate (the "Acquired Shelard
Business") for the year ended December 31, 1994. This financial statement is
the responsibility of Acquired Shelard Business' management. Our
responsibility is to express an opinion on this financial statement based on
our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statement is free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statement. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
  In our opinion, the financial statement referred to above presents fairly,
in all material respects, the results of operations of the Acquired Shelard
Business for the year ended December 31, 1994 in conformity with generally

                         YEAR ENDED DECEMBER 31, 1994
 
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
 
  The Shelard Group, Inc. and affiliate (collectively "Shelard") includes the
accounts of The Shelard Group, Inc. and one of its affiliates, SCI Services,
Inc. Shelard provided property management, commercial brokerage and
construction management services in Minnesota. The accompanying financial
statement includes only the revenue and expenses arising from the operations
of Shelard related to the management, commercial brokerage and construction
management business that was acquired by Koll Management Services, Inc. in
July 1995 (the "Acquired Shelard Business"). This statement is not intended to
and does not reflect the results of operations of Shelard for the period
presented. All significant intercompany transactions have been eliminated in
combination.
 
  The financial information included herein may not necessarily reflect the
results of the operations of the Acquired Shelard Business in the future or
what the results of operations of the Acquired Shelard Business would have
been had it been a separate, stand-alone company.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses for the
period presented. Actual results could differ from those estimates.
 
REVENUE
 
  Revenue consists primarily of property and construction management fees and
leasing and brokerage commissions. Management and construction fees are
generally recognized as the services are rendered. Leasing and brokerage
commissions are recognized when earned, generally upon the closing of the
related transaction.
 
DEPRECIATION AND AMORTIZATION
 
  Depreciation of property and equipment was computed principally using the
straight-line method over the estimated useful lives of the assets.
Amortization of leasehold improvements is completed using the straight-line
method over the lease term or estimated useful lives of the improvements,
whichever is shorter.
 
INCOME TAXES
 
  For federal and state purposes, Shelard has elected under the Internal
Revenue Code to be taxed as an S corporation. In lieu of corporate income
taxes, the shareholders of an S corporation are taxed on their proportionate
share of the company's taxable income. Therefore, no provision or liability
for federal income taxes has been included in the financial statement.
 
3. RELATED PARTY TRANSACTIONS
 
  Included in fee-based services revenue is revenue from affiliates totaling
$709,000.
 
4. OPERATING LEASES
 
  Shelard occupies office space under two operating leases with a related
party. One lease, commencing on July 15, 1994, provides for payments ranging
from $78,000 to $87,000 annually and expires on June 30, 1997;

            NOTES TO COMBINED STATEMENTS OF OPERATIONS--(CONTINUED)
 
the other lease provides for payments ranging from $156,000 to $178,000
annually and expires December 31, 2000. Prior to the July 1994 lease, Shelard
occupied office space under an operating lease which expired in June 1994.
 
  Future commitments under these operating leases at December 31, 1994 were as
follows:

  Rental expense was $253,000 for the year ended December 31, 1994.
 
5. SALARY SAVINGS AND PROFIT SHARING PLAN
 
  Shelard established a Salary Savings and Profit Sharing Plan in 1989 under
Section 401(k) of the Internal Revenue Code in which both the Company and
eligible employees contribute. Shelard's contribution is 50% of employee
contributions based on the first 4% of employee salary deferral. Profit
sharing expense for the year ended December 31, 1994 was $57,000.

standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of Ross-Dove
Company, Inc., Dovetech, Inc., Dovemedia, Ltd. and Dove Capital, Inc. as of
December 31, 1994, and the results of their operations and their cash flows
for the year ended December 31, 1994 in conformity with generally accepted
accounting principles.

1. BASIS OF PRESENTATION, ORGANIZATION AND BUSINESS:
 
BACKGROUND
 
  The accompanying financial statements combine the accounts of Ross-Dove
Company, Inc. (Ross-Dove), Dovetech, Inc. ("Dovetech"), Dovemedia, Ltd.
("Dovemedia") and Dove Capital, Inc. ("Dovecapital") (collectively the
"Company") for all periods presented. All significant intercompany
transactions between Ross-Dove, Dovetech, Dovemedia and Dovecapital have been
eliminated.
 
  Ross-Dove was incorporated on January 25, 1985. Its principal line of
business is conducting auctions. Subsequent to March 13, 1995, Ross-Dove
changed its name to The Dove Holdings Corporation (Dove Holdings).
 
  Dovetech was incorporated on February 6, 1992. On November 24, 1992, all of
the assets, liabilities and obligations of the appraisal business of Ross-Dove
totaling net assets of $30,000 were transferred to Dovetech in exchange for
the issuance of 300 shares of common stock. On November 25, 1992, Dove
Holdings distributed as a dividend all of these shares of Dovetech common
stock on a pro rata basis to the shareholders of Ross-Dove common stock. Its
principal line of business is the provision of asset appraisal services.
 
  Dovemedia was also incorporated on February 6, 1992 and is owned by the same
shareholders as the entities referred to above. Its principal line of business
is providing advertising services to Ross-Dove, the revenue from which
totalled $350,000 in 1995, $3,847,000 in 1994 and $2,665,000 in 1993 and is
eliminated in combination.
 
  Dovecapital was incorporated on April 15, 1994 and is owned by the same
shareholders as Ross-Dove. Dovecapital specializes in asset pricing and
disposition strategies.
 
  On November 23, 1995, Dovemedia and Dovecapital were merged into Dove
Holdings.
 
FORMATION OF KOLL-DOVE GLOBAL DISPOSITION SERVICES LLC
 
  In March 1995, the Company entered into a series of agreements with Koll
Management Services, Inc. (Koll), a real estate services company headquartered
in Newport Beach, California, including:
 
    (1) the formation of a limited liability company, Koll-Dove Global
  Disposition Services LLC (Koll-Dove), to which substantially all of the
  Company's non-real estate assets and related liabilities, excluding the
  receivables from shareholders, were contributed,
 
    (2) the contribution by Koll of $5 million to Koll-Dove in exchange for a
  50 percent ownership interest (subsequently increased to 50.1 percent);
  Koll made a $2 million payment to the Company in March, 1995 which was
  subsequently remitted to Koll-Dove and an additional $3 million payment was
  made to Koll Dove during 1995,
 
    (3) the execution of employment agreements and buy/sell agreements by the
  Company's shareholders.
 
  The accompanying financial statements exclude the activities not
subsequently included in Koll-Dove and accordingly represent only the business
acquired by Koll. The net assets not acquired by Koll have been reflected as a
reduction in the combined statements of shareholders' equity (deficit).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
REVENUE RECOGNITION
 
  The Company's commission income from auctions is recognized upon completion
of the related auction and when there are no significant uncertainties as to
ultimate collection of auction proceeds. Revenues from appraisal and
advertising services are recognized when the services are performed. Costs
related to appraisal services are included within general and administrative
expenses in the accompanying combined statements of operations. Reimbursements
of expenses incurred by the Company in connection with auctions represented

period ended March 13, 1995 and the years ended December 31, 1994 and 1993,
respectively.

  Customer A is a government agency.
 
CASH IN TRUST
 
  The Company generally collects the gross proceeds of an auction on behalf of
the selling parties and holds such proceeds in a trust account until the final
settlement date of the auction. Such amounts held at year-end are shown as
cash in trust in the accompanying combined balance sheets. Cash in trust is
excluded from cash for purposes of the combined statements of cash flows.
 
  The portion of the proceeds that must be remitted to the owner of the goods
that were sold during an auction is reflected as a trust account liability in
the accompanying combined balance sheets, net of the Company's commissions and
expense reimbursements that have not been disbursed from the trust account.
 
LEASES
 
  Leases for which the Company assumes substantially all property rights and
risks of ownership are considered capital leases and are capitalized as
property and equipment. The related obligation is shown in debt as capital
lease obligations. All other leases are considered operating leases and rental
payments are charged to expense as incurred.
 
INCOME TAXES
 
  As the Company's tax filing status is that of an S corporation (and,
subsequent to March 13, 1995, a limited liability company), taxable income or
loss is generally passed through to the individual shareholders of the Company
for tax reporting purposes. Through December 31, 1993, the Company was subject
to a 2 1/2% California state income tax on its taxable earnings. Effective
January 1, 1994, the rate was reduced to 1 1/2% of taxable income.
 
  The benefit relating to the 1994 net operating losses has been fully
reserved, under the provisions of Statement of Financial Accounting Standards
No. 109 "Accounting for Income Taxes."

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 
3. NOTES PAYABLE AND LINES OF CREDIT:
 
  At December 31, 1994, the Company had a note payable to a financial
institution with an outstanding balance of $2,603,000. This note bore interest
at the prime rate (as announced by the N.Y. Clearinghouse Association) plus
1.5% and was paid during 1995. This note was secured by personal guarantees of
the shareholders.
 
  At December 31, 1994, the Company had an installment note payable to a bank
with an outstanding balance of $318,333 and $375,000, respectively. This note
bore interest at the bank's base rate plus .5% and matured on June 30, 1995.
 
4. PROFIT-SHARING PLAN:
 
  Effective June 1, 1985, the Company adopted a 401(k) profit sharing plan
(the "Plan") for the benefit of its employees. Profit sharing contributions to
the Plan are made at the discretion of the Company and members of the Plan may
make voluntary contributions. In addition, effective January 1, 1992, the
Company began matching employee contributions. The Company's contributions for
year ended December 31, 1994 was approximately $150,000 and is included in
general and administrative expenses in the accompanying combined statements of
operations.
 
  In January 1995, the Company amended the Plan to provide for participant
directed investments and to discontinue matching of employee contributions.
Koll-Dove assumed the rights and obligations of the Plan pursuant to the
formation of Koll-Dove as discussed in Note 1.
 
5. COMMITMENTS AND CONTINGENCIES:
 
  The Company is involved in certain legal matters, all of which in the
opinion of management are normal business matters that will not result in a
material adverse effect on the financial position or results of operations of
the Company.
 
  Effective May 31, 1996, the Company agreed to settle litigation which
alleged certain claims arising from an appraisal performed. The settlement
resolved prior litigation which initially ruled in the Company's favor but was
reversed on appeal. The $1 million settlement is due in installments
commencing June 1, 1996 to October 1, 1997.
 
  The Company leases office space and telephone equipment under operating
leases. Rental expense under these leases was $281,000 in 1994. These
operating leases are noncancellable and have minimum lease payment
requirements of $198,000 in 1995, $133,000 in 1996, $96,000 in 1997 and $8,000
in 1998.
 
6. LOSS ON IBM PRODUCT AUCTION:
 
  In July 1994, the Company recognized a loss of approximately $1.2 million on
revenues of approximately $7.3 million related to an auction of IBM products.
This auction was unusual due to the size of the auction and the infrequent
nature of purchased merchandise auctions. The Company intends to limit the
size and frequency of future purchased merchandise auctions.

                                  THE MERGER
 
  2.1 Effective Time of the Merger. Subject to the provisions of this
Agreement, including the satisfaction or waiver of the conditions set forth in
Article 11 hereof, a Certificate of Merger shall be duly prepared, executed
and acknowledged by the Surviving Corporation (as defined in Section 2.2) and
thereafter delivered to the Secretary of State of the State of Delaware, for
filing, in accordance with the Delaware General Corporation Law on the Closing
Date (as defined in Article 12). The Merger shall become effective upon the
filing of the Certificate of Merger with the Delaware Secretary of State (the
"Effective Time").
 
  2.2 Effects of the Merger. At the Effective Time, the separate existence of
Acquisition Corporation shall cease and Acquisition Corporation shall be
merged with and into Koll, which shall be the surviving corporation (the
"Surviving Corporation"); the Certificate of Incorporation of Acquisition
Corporation immediately prior to the Effective Time shall be the Certificate
of Incorporation of the Surviving Corporation; the Bylaws of Acquisition
Corporation shall be the Bylaws of the Surviving Corporation; the directors of
the Surviving Corporation shall be as set forth in Section 2.5 hereof; the
officers of the Surviving Corporation shall be as set forth in Section 2.5
hereof; and the Merger shall, from and after the Effective Time, have all the
effects provided by applicable law, including the Delaware General Corporation
Law.
 
  2.3 Effect on Capital Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any of the issued
and outstanding shares of Koll Common:
 
  (a) Capital Stock of Acquisition Corporation. All issued and outstanding
shares of capital stock of Acquisition Corporation shall continue to be issued
and shall be converted into 1,000 shares of Common Stock of the Surviving
Corporation. Each stock certificate of Acquisition Corporation evidencing
ownership of any such shares shall continue to evidence ownership of such
shares of capital stock of the Surviving Corporation.
 
                                      1-4
<PAGE>
 
  (b) Cancellation of Koll-Owned and CBC-Owned Stock. All shares of Koll
Common, if any, that are owned directly or indirectly by Koll and by CBC or
any of its Subsidiaries shall be canceled, and no stock of CBC or other
consideration shall be delivered in exchange therefor.
 
  (c) Conversion of Koll Common. Other than shares to be canceled pursuant to
Section 2.3(b), Dissenting Shares and fractional shares as provided in Section
2.3(e) and (f), each share of Koll Common issued and outstanding immediately
prior to the Effective Time shall be converted, without any action on the part
of the holders thereof, into (i) 0.776175 shares of CBC Common subject to
adjustment as set forth in Section 2.3(d) (hereinafter the "Stock Exchange
Ratio") and (ii) a number of Warrants (the "Warrants") equal to (A) 600,000
divided by (B)(1) the number of shares of Koll Common outstanding and held by
immediately prior to the Effective Time plus (2) the number of shares of Koll
Common into which Koll Options outstanding and held by individuals who are
directors, employees or consultants of Koll or Subs immediately prior to the
Effective Time are exercisable (the "Warrant Exchange Ratio"); each Warrant
shall be exercisable into one share of CBC Common at an exercise price of
$30.00 per share of CBC Common. In addition, each Warrant shall have a term of
7 years from the Closing Date, shall become exercisable on the third
anniversary of the Closing Date, shall be subject to the terms and conditions
of the Warrant Agreement attached hereto as Exhibit B and shall be in
substantially the form of the Warrant Certificate attached as an Exhibit
thereto. Anything to the contrary contained herein notwithstanding, (i) the
number of shares of Koll Common (including Dissenting Shares and fractional
shares) and securities exercisable or convertible into Koll Common (including
without limitation Koll Options) issued and outstanding immediately prior to
the Effective Time shall not exceed 7,233,243, (ii) the number of shares of
CBC Common issued in exchange for Koll Common pursuant hereto shall not exceed
5,614,261 minus the Stock Exchange Ratio multiplied by the sum of the number
of Dissenting Shares plus the number of fractional shares and (iii) the number
of shares of CBC Common into which all Warrants issued pursuant hereto shall
be exercisable shall not exceed 600,000.
 
  (d) Adjustment of Exchange Ratio. If, between the date of this Agreement and
the Effective Time, the outstanding shares of CBC Common or Koll Common shall
have been changed into a different number of shares or a different class by
reason of any reclassification, recapitalization, split-up, combination,
exchange of shares or readjustment, the Stock Exchange Ratio shall be
correspondingly adjusted. In addition, for each $100,000 by which Bank
Indebtedness exceeds $47,375,000 or by which any subcategory of Bank
Indebtedness exceeds the applicable sublimit (but without duplication), the
Stock Exchange Ratio shall be reduced by .0005883.
 
  (e) Dissenters' Rights of Stockholders of Koll. Any Dissenting Shares shall
not be converted into CBC Common and Dissenting Stockholders shall not have
the right to receive any Warrants. Dissenting Shares shall be converted into
the right to receive such consideration as may be determined pursuant to
Section 262 of the Delaware General Corporation Law, if the Dissenting
Stockholder holding such shares is entitled to dissenters' rights under such
section. Koll agrees that, except with the prior written consent of CBC, or as
required under the Delaware General Corporation Law, it will not voluntarily
make any payment with respect to, or settle or offer to settle, any such
demand for appraisal. Each Dissenting Stockholder who, pursuant to the
provisions of Section 262 of the Delaware General Corporation Law, and subject
to any agreements binding upon such Dissenting Stockholder, becomes entitled
to payment of the value of shares of Koll Common shall receive payment
therefor (but only after the value therefor shall have been agreed upon or
finally determined pursuant to such provisions). In the event of the legal
obligation, after the Effective Time, to deliver shares of CBC Common to any
Dissenting Stockholder who shall have failed to make an effective demand for
appraisal or shall have lost his status as a Dissenting Stockholder, CBC shall
issue and deliver, upon surrender by such Dissenting Stockholder of his
certificate or certificates representing shares of Koll Common, the shares of
CBC Common, Warrants and payments in lieu of fractional shares to which such
Dissenting Stockholder is then entitled under this Section 2.3 and Section 262
of the Delaware General Corporation Law.
 
  (f) Fractional Shares. No fractional shares of CBC Common shall be issued,
but in lieu thereof each holder of shares of Koll Common who would otherwise
be entitled to receive a fraction of a share of CBC Common (after aggregating
all fractional shares of CBC Common to be received by such holder) shall
receive from CBC an amount of cash (rounded up to the nearest whole cent)
equal to the product of the fraction of a share of CBC
 
                                      1-5
<PAGE>
 
Common to which such holder would otherwise be entitled, times the average
closing sale price of a share of CBC Common for the ten (10) most recent days
on which CBC Common has traded ending the trading day immediately prior to the
Closing Date, as reported on the Nasdaq National Market ("NASDAQ"). Each
holder of Koll Common will be issued one certificate representing all Warrants
to which it is entitled rounded down to the nearest whole number.
 
  2.4 Exchange of Certificates. At the Closing, each holder of shares of Koll
Common other than Dissenting Stockholders will surrender the certificate(s) (a
"Certificate") representing such shareholder's shares of Koll Common to CBC.
Upon surrender of a Certificate for cancellation to CBC, the holder of such
Certificate shall be entitled to receive in exchange therefor the number of
shares of CBC Common (represented by a certificate), payments in lieu of
fractional shares and Warrants to which the holder of Koll Common is entitled
pursuant to Section 2.3 and the Certificate of Merger and is represented by
the Certificate so surrendered. The Certificate so surrendered shall forthwith
be canceled. In the event of a transfer of ownership of Koll Common which is
not registered in the transfer records of Koll, the appropriate number of
shares of CBC Common may be delivered to a transferee if the Certificate
representing the right to receive such CBC Common is presented to CBC and
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable stock transfer taxes have been paid. Until
surrendered as contemplated by this Section 2.4, each Certificate shall be
deemed at any time after the Effective Time to represent the right to receive
upon such surrender the number of shares of CBC Common as provided by this
Section 2.4 and the Delaware General Corporation Law. CBC shall follow the
same procedure with respect to lost, stolen or mutilated Koll certificates as
it follows with respect to lost, stolen or mutilated CBC certificates. Unless
and until any such certificates shall be so surrendered, any dividends paid or
other distributions made to holders of record of CBC Common after the
Effective Time shall be retained by CBC and paid over to such holder when such
certificate is surrendered in accordance with this Section 2.4(c).
 
  2.5 Board of Directors; Officers. Upon the Effective Time:
 
  (a) The directors of the Surviving Corporation shall be as named in the
Certificate of Merger and each shall remain a director from the Effective Time
until such director's successor shall have been elected and shall qualify, or
as otherwise provided in the By-laws of the Surviving Corporation.
 
  (b) The officers of the Surviving Corporation shall be as named in the
Certificate of Merger and shall each hold office from the Effective Time until
such officer's successor shall have been elected and shall qualify, or as
otherwise provided in the By-laws of the Surviving Corporation.
 
  (c) If at the Effective Time a vacancy shall exist in the Board of Directors
or in any of the offices of the Surviving Corporation, such vacancy may
thereafter be filled in the manner provided in the Bylaws of the Surviving
Corporation.
 
  2.6 No Further Ownership Rights in Koll Common. All CBC Common delivered
upon the surrender for exchange of shares of Koll Common in accordance with
the terms hereof shall be deemed to have been delivered in full satisfaction
of all rights pertaining to such shares of Koll Common. There shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Koll Common which were outstanding immediately
prior to the Effective Time. If, after the Effective Time, Certificates are
presented to the Surviving Corporation for any reason, they shall be canceled
and exchanged as provided in this Article 2.
 
  2.7 Tax Treatment. The parties intend that the Merger will be treated as a
reorganization under Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal
Revenue Code of 1986, as amended (the "Code"), and that this Agreement be
treated as a Plan of Reorganization for such purpose.
 
  2.8 Employee Stock Options. All options to purchase shares of Koll Common
("Koll Options") outstanding as of the Effective Time under Koll option plans
shall be treated in accordance with Section 10.12.

  3.5 Authority.
 
  (a) Each of Koll and each of the Koll Shareholders and DMK has all requisite
individual, corporate or partnership, as applicable, power and authority to
enter into this Agreement and the Certificate of Merger and, subject to
satisfaction of the conditions set forth herein, to consummate the
transactions contemplated hereby and thereby. The execution and delivery of
this Agreement and the Certificate of Merger and the consummation of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary action, corporate, partnership or otherwise, on the part of each of
Koll and each of the Koll Shareholders subject to approval by the stockholders
of Koll. This Agreement has been duly executed and delivered by each of Koll
and each of the Koll Shareholders and DMK and constitutes a valid and binding
obligation of Koll and each of the Koll Shareholders and DMK enforceable in
accordance with its terms, subject to the approval of the stockholders of
Koll.
 
  (b) Provided the conditions in Article 11 are satisfied, the execution and
delivery of this Agreement does not, and the consummation of the transactions
contemplated hereby will not, conflict with, or result in any violation of or
default (with or without notice or lapse of time, or both) under, or give rise
to a right of termination, cancellation or acceleration of any obligation or
to loss of a material benefit under (i) any provision of the charter documents
or Bylaws of Koll or Subs or any Koll Shareholder or (ii) any material
agreement or instrument, permit, franchise, license, judgment or order,
applicable to Koll or Subs or any Koll Shareholder or their respective
properties or assets, other than any such conflicts, violations, defaults,
terminations, cancelations
 
                                      1-8
<PAGE>
 
or accelerations which individually or in the aggregate would not have a
Material Adverse Effect. Schedule 3.5 contains a full and complete list of all
necessary consents, waivers and approvals (together with any other consents,
waivers or approvals from third parties, the "Consents") of third parties
(other than Governmental Entities) applicable to the operations of Koll and
Subs that are required to be obtained by Koll and Subs in connection with the
execution and delivery of this Agreement or the Certificate of Merger by Koll
and the performance of Koll's obligations hereunder or thereunder, except for
such Consents for which the failure to obtain the same would not have a
Material Adverse Effect. Prior to the Closing Date, Koll or Subs, as
applicable, will obtain all Consents the failure of which to obtain would have
a Material Adverse Effect, other than with respect to that certain Amended and
Restated Credit Agreement, dated as of January 9, 1997, among Koll Management
Services, Inc., the Lenders listed therein, Bankers Trust Company, as agent
for the Lenders, and The First National Bank of Boston and BHF-Bank
Aktiengesellschaft, as co-agents for the Lenders, as amended, with respect to
which Koll will obtain, prior to Closing, the Lenders' consent to an extension
of such Credit Agreement until sixty (60) days following the Effective Time as
set forth in Section 11.2(n). Notwithstanding the foregoing, Koll will not
obtain any consents under its or its Affiliates' property or facilities
management agreements, provided, however, that if any such property or
facilities management agreements are terminated pursuant to any "Change of
Control", "Assignment", or similar provision and such terminations,
individually or in the aggregate and subject to Section 6.1, have a Material
Adverse Effect, it shall constitute the failure of a condition to CBC's and
Acquisition Corporation's respective obligations to close. Subject to the
immediately following paragraph, no such Consents are required to be obtained
by the Koll Shareholders in connection with the execution and delivery of this
Agreement or the performance of their obligations hereunder.
 
  (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any national (Federal or foreign), state or local
government, any political subdivision thereof or any governmental, quasi-
governmental, judicial, public or statutory agency, commission, authority,
instrumentality, body or entity (a "Governmental Entity"), is required by or
with respect to Koll or Subs or the Koll Shareholders in connection with the
execution and delivery of this Agreement by Koll and the Koll Shareholders or
the Certificate of Merger by Koll or the consummation by Koll and the Koll
Shareholders of the transactions contemplated hereby or thereby, except for
(i) the filing of a pre-merger notification report under the Hart-Scott-Rodino
Act ("HSR Act"), (ii) the filing of a Form S-4 with the SEC, (iii) the filing
of the Certificate of Merger with the Delaware Secretary of State, and
appropriate documents with the relevant authorities of other states in which
Koll is qualified to do business, (iv) the filing of the Proxy Statement with
the SEC in accordance with the Securities Exchange Act of 1934 (the "Exchange

declarations and filings as may be required under applicable state securities
laws and the laws of any foreign country, and (vi) such other consents,
approvals, orders, authorizations, registrations, declarations and filings
which if not obtained or made would not have a Material Adverse Effect.

Closing Date, which monthly financial statements shall contain substantially
all the information currently contained in what is commonly referred to as the
"Green Book." The unaudited consolidated balance sheet at March 31, 1997 is

consistent basis during the periods involved, except as noted in the notes to
the Koll Financial Statements, and are and will be in accordance with Koll's
books and records, and fairly present in all material respects the financial
position of Koll and the results of its operations as of the date and for the
periods indicated thereon, subject in the case of the unaudited portion of the
Koll Financial Statements to normal year-end audit adjustments which will not
be material and the absence of certain footnote disclosures. At the date of

plan, agreement, trust, fund or arrangement for the benefit of employees of
any kind whatsoever, nor entered into or amended any agreement relating to
employment, services as an independent contractor or consultant, or severance

of the real and personal property used by Koll and Subs in their business or
otherwise held by Koll and Subs, except for property acquired or disposed of
in the ordinary course of the business of Koll and Subs since the date of such
balance sheet, and personal property or leasehold interests not required under
GAAP to be reflected thereon. Koll and Subs have good and marketable title to
all assets and properties reflected on the Koll Balance Sheet and thereafter
acquired, free and clear of any imperfection of title, lien, claim,
encumbrance, restriction, charge or equity of any nature whatsoever
(collectively, "Liens"), except for (i) the lien of current taxes not yet
delinquent (ii) Liens which, individually or in the aggregate, would not have
a Material Adverse Effect and (iii) Liens existing as of the date hereof under
credit facilities existing as of the date hereof. All of the fixed assets and
properties listed on the Koll Balance Sheet or thereafter acquired are in
satisfactory condition and repair for the requirements of the business as
presently conducted by Koll and Subs, except for imperfections that would not
have a Material Adverse Effect.
 
  3.9 Real Property.
 
  (a) Attached hereto as Schedule 3.9(a) is a full and complete list of all
real property owned and leased by Koll or Subs, which, in the case of leased
real property, is subject to annual rental payments in excess of $30,000 or
under option to purchase by Koll or Subs. All such property leased by Koll or
Subs is held under valid, subsisting and enforceable leases, except for
imperfections which would not have a Material Adverse Effect. Neither real
property owned or leased by Koll or any of its Subs nor the operations of Koll
or Subs thereon, violate any applicable building code, zoning requirement or
classification, or pollution control ordinance or statute relating to the
property or to such operations, and such non-violation is not dependent, in
any instance, on so-called non-conforming use exemptions, except for such
violations as would not have a Material Adverse Effect. No notice from any
governmental or public safety authority of any uncorrected condition, unpaid

  (b) Except as disclosed on Schedule 3.9(b), there are no Hazardous
Substances in, under or about the air, soil, sediment, surface water or
groundwater on, under or around any properties at any time owned, leased or
occupied by Koll or any of its Subs which would have a Material Adverse
Effect. Neither Koll nor Subs have disposed of any Hazardous Substances on or
about such property which would have a Material Adverse Effect. Neither Koll
nor any of its Subs have disposed of any materials at any site being
investigated or remediated for contamination or possible contamination of the
environment which would have a Material Adverse Effect. "Hazardous Substances"
shall mean any substance regulated or prohibited by any law or designated by
any governmental agency to be hazardous, toxic, radioactive, regulated medical
waste or otherwise a danger to health or the environment.
 
  (c) Koll and Subs have conducted their business in accordance with all
applicable laws, regulations, orders and other requirements of governmental
authorities relating to Hazardous Substances and the use, storage, treatment,
disposal, transport, generation, release and exposure of others to Hazardous
Substances (collectively, "Environmental Regulation"), except for such
noncompliance as would not have a Material Adverse Effect. Except as set forth
on Schedule 3.9(c), Koll has not received any notice of any investigation,
claim or proceeding against Koll or Subs relating to Hazardous Substances and
Koll is not aware of any fact or circumstance which could involve Koll or Subs
in any environmental litigation, proceeding, investigation or claim or impose
any environmental liability upon Koll or any of its Subs (collectively,
"Environmental Litigation") which if resolved adversely to Koll or any Sub
would have a Material Adverse Effect. Between the date hereof and Closing,
there shall not have occurred any failure by Koll or Subs to comply with
applicable Environmental Regulation and there shall not have occurred any
Environmental Litigation that, in each case, would have a Material Adverse
Effect on Koll or any of its Subs.
 
  3.10 Accounts Receivable. All of the accounts receivable of Koll and Subs
shown on the Koll Balance Sheet or arising between the Koll Balance Sheet Date
and the Effective Time arose or will arise in the ordinary course of their
respective businesses. The values at which accounts receivable are carried
reflect the accounts receivable valuation policy of Koll which is consistent
with past practice and in accordance with GAAP applied on a consistent basis.
 
  3.11 Taxes. Koll and Subs have duly filed with the appropriate United
States, state, local and foreign governmental agencies all tax returns and
reports required to be filed (subject to permitted extensions applicable to
such filings), which returns are accurate and complete, and have paid or
accrued in full all taxes, duties, charges, withholding obligations and other
governmental liabilities (including, without limitation, net income,
alternative or add-on minimum tax, profits, premium, estimated, excise, sales,
use, occupancy, gross income, gross receipts, franchise, ad valorem, stamp,
severance, capital levy, production, transfer, withholding, license,
employment and payroll, and property taxes, environmental or windfall profits
taxes and import duties) as well as any interest, penalties, assessments or
deficiencies, if any, due to, or claimed to be due by, any governmental
authority (All such items are collectively referred to herein as "Taxes"). The
Koll Balance Sheet fully accrues (and the balance sheets subsequent to the
date of the Koll Balance Sheet and provided to CBC prior to the Closing Date
will fully accrue) all current and deferred Taxes, as required in accordance
with GAAP. Except as set forth on Schedule 3.11, neither Koll nor Subs is a
party to any pending actions or proceedings, nor, to the knowledge of Koll,
are any such actions or proceedings threatened by any governmental authority
for the assessment or collection of Taxes except for such actions or
proceedings which, if resolved adversely, individually or in the aggregate,
would not have a Material Adverse Effect. Since March 31, 1996, no liability
for Taxes has been incurred other than in the ordinary course of business.
There are no liens for Taxes which are material, individually or in the
aggregate, except for liens for property taxes not yet delinquent. Except as
set forth on Schedule 3.11, neither Koll nor Subs is a party to any Tax
sharing, Tax allocation or Tax indemnity agreement and in the past five (5)
years has not been included on any consolidated combined or unitary return
with any entity other than Koll or Subs.
 
  3.12 Compensation. Except as set forth on Schedule 3.12, since March 31,
1997, neither Koll nor Subs has paid or committed itself to pay to or for the
benefit of any of its directors, officers, employees or stockholders any

at times and rates in effect
 
                                     1-12

and commissions) is currently $100,000 or more, together with a detailed
statement setting forth their respective salaries, bonuses, any incentive
payments, perquisites, benefits and other forms of compensation and any
amounts payable as a result of a change in control of Koll or Subs and to
which they are entitled or would become entitled after the Merger.
 
  3.13 Compliance with Law. All licenses, franchises, permits, consents,
certificates and other evidences of authority ("Permits") of Koll and Subs
which are necessary to the conduct of Koll and Subs' businesses are in full
force and effect, except for such Permits where the failure to obtain same or
the failure of same to be in full force and effect would not have a Material
Adverse Effect, and neither Koll nor Subs is in violation of any Permit in any
respect that would have a Material Adverse Effect. Except for possible
violations which would not have a Material Adverse Effect, the business of
Koll and Subs has been conducted in accordance with all applicable laws,
regulations, orders and other requirements of governmental authorities.
 
  3.14 Litigation. Except as set forth on Schedule 3.14 and except for normal
authorizations, permits and orders issued in the ordinary course of business,

at law or in equity, pending against Koll or Subs, or involving any of their
respective assets or properties, before any court, agency, governmental
department or agency, commission, authority, arbitration panel or other
tribunal (other than those, if any, with respect to which service of process
or similar notice has not yet been made on Koll or Subs), and, to the
knowledge of Koll and Subs, none have been threatened which, in each case,
would have a Material Adverse Effect. There are no facts which, if known to
stockholders, customers, governmental authorities or other persons, would
result in any such claim, dispute, action, proceeding, suit or appeal or
investigation which would have a Material Adverse Effect. Except as set forth
on Schedule 3.14, neither Koll nor Subs is subject to any order, writ,
injunction or decree of any court, agency, authority, arbitration panel or
other tribunal, nor is it in default with respect to any notice, order, writ,
injunction or decree.

  3.16 No Default.
 
  (a) Each of the contracts, agreements or other instruments set forth in
Schedule 3.15, each of the real property leases set forth in Schedule 3.9(a)
and each of the employment agreements or contracts of Koll or Subs is a legal,
binding and enforceable obligation of Koll or Subs, subject to the effect of
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
federal or state laws affecting the rights of creditors and the effect or
availability of rules of law governing specific performance, injunctive relief
or other equitable remedies (regardless of whether any such remedy is
considered in a proceeding at law or in equity), except for such contracts,
agreements and other instruments the failure of which, individually or in the
aggregate, to be legal, binding and enforceable would not have a Material
Adverse Effect. No party with whom Koll or Subs has an agreement or contract
is in default thereunder or has breached any terms or provisions thereof which
default or breach would reasonably be expected to have a Material Adverse
Effect.
 
  (b) Koll and Subs have performed, or are now performing, the obligations of,
and Koll and Subs are not in default (or would by the lapse of time and/or the
giving of notice be in default) in respect of, any contract, agreement or
commitment binding upon their respective assets or properties, except for
noncompliance or defaults as would not have a Material Adverse Effect. Except
for those matters which, individually or in the aggregate, do not and will not
have a Material Adverse Effect, (i) no third party has raised any claim,
dispute or controversy with respect to any of the contracts of Koll and Subs,
nor (ii) has Koll or Subs received notice or warning of alleged
nonperformance, delay in delivery or other noncompliance by Koll or Subs with
respect to their respective obligations under any of their respective
contracts, nor (iii) are there any facts which exist indicating that any of
their contracts may be totally or partially terminated or suspended by the
other parties thereto.
 
  3.17 Proprietary Rights.
 
  (a) (i) Each of Koll and Subs owns or possesses licenses or other rights to
use all computer software, software programs, patents, patent applications,
trademarks, trademark applications, trade secrets, service marks, trade names,
copyrights, inventions, customer lists, proprietary information, or other
rights with respect thereto (collectively referred to as "Proprietary
Rights"), used in the business of Koll and Subs, except for those Proprietary
Rights with respect to which the failure of Koll or Subs to own or license
would not have a Material Adverse Effect, and (ii) those Proprietary Rights
owned or licensed are sufficient to conduct the business of Koll and Subs as
it has been and is now being conducted.
 
  (b) The operations of Koll or Subs do not conflict with or infringe, and no
one has asserted to Koll or Subs that such operations conflict with or
infringe, any Proprietary Rights of any third party. There are no claims,
disputes, actions, proceedings or suits pending against Koll or Subs with
respect to any Proprietary Rights (other than those with respect to which
service of process or similar notice may not yet have been made on Koll or
Subs), and, to the knowledge of Koll and Subs, none has been threatened
against Koll or Subs. There are no facts or alleged facts which would
reasonably serve as a basis for any claim that Koll or Subs does not have the
right to use, free of any rights or claims of others, all Proprietary Rights
in the conduct of the business of Koll and Subs as it has been and is now
being conducted.
 
  3.18 Insurance. As of the date of this Agreement, Schedule 3.18 contains a
complete list of all material policies of insurance to which Koll or Subs is a
party or is a beneficiary or named insured and all material claims which have
been made to the insurers during the past five years. Koll and Subs have in
full force and effect, with all premiums due thereon paid, the policies of
insurance set forth therein, except where the failure so to do would not have
a Material Adverse Effect. Koll believes that the insurable properties of Koll
and Subs are insured in amounts and coverages and against risks and losses
which are adequate and usually insured against by persons holding or operating
similar properties in similar businesses. There were no claims in excess of
policy limits asserted under any of the material insurance policies of Koll
and Subs in respect of all motor vehicle, general liability, fidelity bonds,
professional liability, reinsurance and workers' compensation, and medical
claims for the period after December 31, 1996 to the date of this Agreement.
The insurers have no right to
 
                                     1-14
<PAGE>
 
terminate or reduce such coverage before the end of applicable policy periods
and Koll and Subs have complied in all material respects with their
obligations under such policies. Koll will promptly notify CBC of any changes
in its insurance coverage occurring between the date hereof and the Effective
Time.

brokerage or finders' fees or agents' commissions or any similar charges in
connection with this Agreement or any transaction contemplated hereby.
 
  3.20 Certain Advances. Except as set forth on Schedule 3.20, there are no
receivables of Koll or Subs owing from directors, officers, employees,
consultants or stockholders of Koll or Subs, or owing by any Affiliate of any
director or officer of Koll or Subs, other than advances in the ordinary
course of business to officers and employees for reimbursable business
expenses which are not in excess of $15,000 individually.
 
  3.21 Related Parties. Except as set forth on Schedule 3.21, no officer or
director of Koll or Subs, or any Affiliate (as defined in Section 10.11
hereof) of any such person, has, either directly or indirectly, an interest in
any corporation, partnership, firm or other person or entity which furnishes
or sells services or products which are similar to those furnished or sold by
Koll or Subs, or a beneficial interest in any contract or agreement to which
Koll or Subs is a party or by which Koll or Subs may be bound. For purposes of
this Section 3.21, there shall be disregarded any interest which arose solely
from the ownership of less than a five percent (5%) equity interest in a
corporation whose stock is regularly traded on any national securities
exchange or in the over-the-counter market.
 
  3.22 Underlying Documents. Copies of any underlying documents listed or
described as having been disclosed to CBC pursuant to this Agreement have been
furnished or made available to CBC. All such documents furnished to CBC are
true and correct copies, and there are no material amendments or modifications
thereto, that have not been disclosed to CBC. The minute books of Koll and
Subs contain complete and accurate records of all meetings and other corporate
actions taken by the directors and stockholders of Koll and Subs.
 
  3.23 Employees and Union Activities. Koll and Subs have complied with all
applicable state and federal laws and regulations related to employees and
employment practices, except where the failure to comply would not have a
Material Adverse Effect on Koll and Subs. As of the date hereof, Koll's
employee relations and those of each of the Subs are good and there is no
pending or threatened labor dispute. As of the date hereof, no union
representation question exists respecting any employees; no collective
bargaining agreement is currently being negotiated by Koll or any of the Subs;
no demand has been made for recognition by a labor organization by or with
respect to any employees; no union organizing activities by or with respect to
any employees are taking place; and none of the employees is represented by
any labor union or organization. Koll with promptly notify CBC of any change
in the foregoing between the date hereof and the Closing Date.
 
  3.24 Employee Benefit Plans.
 
  (a) Except as set forth in Schedule 3.24(a) (collectively, the "Koll
Plans"), neither Koll nor any ERISA Affiliate as of the Effective Time,
sponsors, maintains, is a party to, contributes to, or is obligated to
contribute to, (i) any Employee Benefit Plan within the meaning of Title I of
ERISA or (ii) any profit sharing, deferred compensation, bonus, stock
purchase, stock option, pension, retirement, severance, welfare, fringe
benefit, incentive, excess benefit (whether funded or unfunded) or cafeteria
plan, agreement or arrangement.
 
  (b) Except as disclosed in Schedule 3.24(b), as of the Effective Time,
neither of Koll nor any ERISA Affiliate sponsors, is a party to, or is
obligated to contribute to, any Multiemployer Plan or any Employee Pension
Benefit Plan which is or was a defined benefit plan or which is subject to
Code Section 412 or Title IV of ERISA. The value, determined on a termination
basis using the actuarial assumptions stated in the plan, of all accrued and
ancillary benefits (whether or not vested) under each defined benefit plan
(other than Multiemployer Plans) maintained by Koll or any of its ERISA
Affiliates did not exceed, as of the most recent valuation date, and will not
exceed as of the Effective Time, the then current fair market value of the
assets of the plan.

Closing (i) complete and accurate copies of the currently effective plan
document of each Koll Plan; (ii) if no such written plan document exists, a
description of such Koll Plan; (iii) any agreements or contracts pursuant to
which custody, funding or administrative services are being provided to Koll
Plans; (iv) with respect to each Koll Plan that is intended to qualify under
section 401(a) of the Code, the most recent determination letter concerning
the plan's qualification under section 401(a) of the Code, as issued by the
Internal Revenue Service; and (v) the current summary plan description,
summary of material modifications, and the most recently filed Form 5500
pertaining to each of the Koll Plans.
 
  (d) Except with respect to Multiemployer Plans, with respect to each Koll
Plan, (i) the applicable reporting, disclosure and record retention
requirements set forth in Part 1 of Subtitle B of Title I of ERISA and any
filing requirements under the Code, including Section 6039D thereof, have been
met on a timely basis, and (ii) there has been no violation of Title I,
Subtitle B, Part 4 of ERISA (pertaining to fiduciary responsibility) nor any
violation of Code Section 4975(c), in each case except for such non-compliance
which would not have a Material Adverse Effect.
 
  (e) Except with respect to Multiemployer Plans, each Koll Plan that is
intended to qualify under section 401(a) of the Code meets in all material
respects all requirements for qualification under section 401(a) of the Code
and the regulations thereunder, except to the extent that such requirements
may be satisfied by adopting prior to the Closing retroactive amendments under
section 401(b) of the Code and the regulations thereunder. Each such Koll Plan
has been administered in all material respects in accordance with its terms
and the applicable provisions of ERISA and the Code and the regulations
thereunder.
 
  (f) Neither Koll nor any ERISA Affiliate has any liability to (i) any Koll
Plan or any plan, agreement or arrangement that would have been required to be
disclosed on Schedule 3.24(a) had Koll sponsored, contributed to, been a party
to, or been obligated to contribute to it as of the Effective Time or (ii) the
PBGC, to any Multiemployer Plan, to any trustee or to any plan participant
under Title IV of ERISA (other than liability for plan contributions which are
not overdue and for premiums under Section 4007 of ERISA), in each case except
for liabilities that would not have a Material Adverse Effect. If Koll and its
ERISA Affiliates withdrew or partially withdrew from all Multiemployer Plans
to which they have an obligation to contribute, based on the latest
information available with respect to such Multiemployer Plans, no withdrawal
liability would be imposed.
 
  (g) All material amounts of contributions, premiums or other payments due
from Koll or any ERISA Affiliate to (or under) any Koll Plan have been fully
paid or adequately accrued on the books and the Koll Financial Statements. All
material amounts of such payments are fully deductible for federal income tax
purposes. No changes affecting any Koll Plan will occur before Closing that
will result in a material increase in the amount of contributions or
liabilities of Koll and its ERISA Affiliates with respect to any Koll Plan.
 
  (h) Except with respect to Multiemployer Plans, each Koll Plan complies in
all material respects with all applicable requirements of the Age
Discrimination in Employment Act of 1967, as amended, and the regulations
thereunder, Title VII of the Civil Rights Act of 1964, as amended, and the
regulations thereunder, the health care continuation provisions of COBRA, the

other applicable law.
 
  (i) Except as set forth on Schedule 3.14, there is no pending or threatened
litigation, or other actions or claims, relating to any Koll Plan or any plan,
agreement or arrangement that would have been required to be disclosed on
Schedule 3.24(a) had Koll sponsored, contributed to, been a party to, or been
obligated to contribute to it as of the Effective Time (other than (i) such
litigation, actions or claims, relating to Multiemployer Plans where neither
Koll nor any of its ERISA Affiliates are parties and (ii) routine claims for
benefits and qualified domestic relations orders) against or involving (i) any
Koll Plan, or (ii) any Fiduciary of such plan (within the meaning of Section
3(21)(A) of ERISA) brought on behalf of any administrative agency (whether
local, state or federal), participant, beneficiary, or Fiduciary thereunder,
nor is there any reasonable basis for any such claim. There are no
investigations, proceedings, or lawsuits, either currently in progress or, to
Koll's knowledge, to be instituted in the future, relating to any Koll Plan,
by any administrative agency (whether local, state, or federal).

  (j) Except as disclosed on Schedule 3.24(j), no payment made to any
employee, officer, director or independent contractor of Koll (the
"Recipient") pursuant to any employment contract, severance agreement or other
arrangement (the "Golden Parachute Payment") will be nondeductible by Koll
because of the application of sections 280G and 4999 of the Code to the Golden
Parachute Payment, nor will Koll be required to compensate any Recipient
because of the imposition of an excise tax (including any interest or
penalties related thereto) on the Recipient by reason of sections 280G and
4999 of the Code.
 
  (k) Neither Koll nor any ERISA Affiliate has any unfunded liability relating
to retiree life and medical benefits for its respective current or former
employees and their dependents, other than any liability under COBRA or state
law conversion rights.

arrangement procured in connection with any Koll Plan in the nature of a
retroactive rate adjustment, loss sharing arrangement, or other similar
liability arising wholly or partially out of events occurring before the
Effective Time, in each case, except for such liabilities which would not have
a Material Adverse Effect. No Koll Plan has any interest in any annuity
contract or other investment or insurance contract issued by an insurance
company that is the subject of bankruptcy, conservatorship, rehabilitation, or
similar proceeding, except for such interests, other investment contracts or
insurance contracts which are not material to such Koll Plan.
 
  (m) None of the persons performing services for Koll have been improperly
classified as independent contractors or as being exempt from the payment of
wages for overtime, except for such improper classifications which would not
have a Material Adverse Effect. No persons classified by Koll as independent
contractors or leased employees are wrongfully excluded from participation in
any Koll Plans or any plan, agreement or arrangement that would have been
required to be disclosed on Schedule 3.24(a) had Koll sponsored, contributed
to, been a party to, or been obligated to contribute to it as of the Effective
Time.

proceeding, suit, appeal or investigation, at law or in equity, pending
against CBC or its Subsidiaries, or involving any of their respective assets
or properties, before any court, agency, governmental department or agency,
commission, authority, arbitration panel or other tribunal (other than those,
if any, with respect to which service of process or similar notice has not yet
been made on CBC or its Subsidiaries), and, to the knowledge of CBC and its
Subsidiaries, none have been threatened, which would have a Material Adverse
Effect on CBC and its Subsidiaries. There are no facts which, if known to
stockholders, customers, governmental authorities or other persons, would
result in any such claim, dispute, action, proceeding, suit or appeal or
investigation which would have a Material Adverse Effect on CBC and its
Subsidiaries. Neither CBC nor its Subsidiaries is subject to any order, writ,
injunction or decree of any court, agency, authority, arbitration panel or
other tribunal, nor is it in default with respect to any notice, order, writ,
injunction or decree.
 
  5.13 Properties. The CBC Balance Sheet reflects all of the real and personal
Property used by CBC and its consolidated Subsidiaries in their respective
businesses or otherwise held by CBC and its Subsidiaries, except for (a)
property acquired or disposed of in the ordinary course of business of CBC and
its Subsidiaries since the date of the CBC Balance Sheet and (b) personal
property or leasehold interests not required under GAAP to be reflected
thereon. The CBC Companies have good and marketable title to all assets and
properties reflected on the CBC Balance Sheet and thereafter acquired, free
and clear of any Lien, except for (i) the lien of current taxes not yet
delinquent (ii) Liens which, individually or in the aggregate, would not have
a Material Adverse Effect and (iii) existing Liens under credit facilities
existing as of the date hereof. All of the fixed assets and properties listed
on the CBC Balance Sheet or thereafter acquired are in satisfactory condition
and repair for the requirements of the business as presently conducted by the
CBC Companies.
 
  5.14 Taxes. CBC and its Subsidiaries have duly filed with the appropriate
United States, state, local and foreign governmental agencies all tax returns
and reports required to be filed (subject to permitted extensions applicable
to such filings), which returns are accurate and complete, and have paid or
accrued in full all Taxes. The CBC Balance Sheet fully accrues (and the
balance sheets subsequent to the date of the CBC Balance Sheet and provided to
Koll prior to the Closing Date will fully accrue) all current and deferred
Taxes to the extent required by GAAP. Neither CBC nor any of its Subsidiaries
is a party to any pending actions or proceedings, nor, to the knowledge of
CBC, are any such actions or proceedings threatened by any governmental
authority for the assessment or collection of Taxes except for such actions or
proceedings which if resolved adversely, individually or in the aggregate,
would have a Material Adverse Effect. Since March 31, 1996, no liability for
Taxes has been incurred other than in the ordinary course of business. There
are no liens for Taxes which are material individually or in the aggregate,
except for liens for property taxes not yet delinquent. Neither CBC nor any of
its Subsidiaries is a party to any Tax sharing, Tax allocation or Tax
indemnity agreement and in the past five (5) years has not been included on
any consolidated combined or unitary return with any entity other than CBC or
Subsidiaries. As of December 31, 1996, CBC and its Subsidiaries had a net
operating loss carryforward for federal tax purposes approximately equal to
$184.3 million and the consummation of the transactions contemplated hereby
will not limit the utilization of such net operating loss carryforward under
Section 382 of the Code.
 
  5.15 No Default. CBC and its Subsidiaries have performed, or are now
performing, the obligations of, and CBC and its Subsidiaries are not in
default (or would by the lapse of time and/or the giving of notice be in
default) in respect of, any contract, agreement or commitment binding upon
their respective assets or properties, except for noncompliance or defaults as
would not have a Material Adverse Effect. Except for those matters which,
individually or in the aggregate, do not and will not have a Material Adverse
Effect, (i) no third party has raised any claim, dispute or controversy with
respect to any of the contracts of CBC and its Subsidiaries, nor (ii) has CBC
or its Subsidiaries received notice or warning of alleged nonperformance,
delay in delivery or other noncompliance by CBC or its Subsidiaries with
respect to their respective obligations under any of their respective
contracts, nor (iii) to the knowledge of CBC and its Subsidiaries, are there
any facts which exist indicating that any of their contracts may be totally or
partially terminated or suspended by the other parties thereto.

                   COVENANTS RELATING TO CONDUCT OF BUSINESS
 
  During the period from the date of this Agreement and continuing until the
Effective Time, Koll shall and shall cause Subs to (except as expressly
contemplated by this Agreement or to the extent that CBC shall otherwise give
its prior consent in writing) comply with the following:
 
  6.1 Ordinary Course. Each of Koll and each of its Subs shall carry on their
business in the regular and ordinary course, including the payment of all
state and federal taxes, in substantially the same manner as heretofore
conducted and, to the extent consistent with such businesses, use all
commercially reasonable efforts consistent with past practice and policies to
preserve intact its present business organization, keep available the services
of its present officers, key employees, agents and representatives and
preserve its goodwill and relationships with existing and potential customers,
employees, independent contractors, clients, suppliers, and others with whom
business relationships exist to the end that its goodwill and ongoing
businesses shall be unimpaired at the Effective Time. Neither Koll nor any Sub
shall enter into any agreement which would prevent Koll from consummating the
transactions contemplated hereby. In determining whether Koll has maintained
relationships with existing customers or clients or whether a loss of
customers or clients has had a Material Adverse Effect under this Agreement, a
customer or client shall not be considered lost if (i) such customer or
client, upon termination of its relationship with Koll or a Koll Affiliate,
(A) contracts with CBC or a CBC Affiliate to substantially provide the same
services previously provided by Koll or a Koll Affiliate or (B) does not
contract with any third party to provide such services (and an Affiliate of
such customer or client shall not be deemed to be a third party) or (ii) such
customer or client terminates its relationship with Koll or a Koll Affiliate
due to the fact that it has sold the property with respect to which Koll or a
Koll Affiliate was rendering services to an unaffiliated third party or has
converted the property into or contributed the property to a real estate
investment trust. In addition, when determining whether Koll has maintained
such relationships, or whether a loss of customers or clients has had a
Material Adverse Effect under this Agreement, the addition of new customers or
clients who have entered into a binding agreement with Koll or a Koll
Affiliate shall be taken into account to offset any loss of customers or
clients.
 
  6.2 Dividends; Changes in Equity. Except as disclosed on Schedule 6.2, Koll
and its Subs and Investment Entities that are not wholly owned shall not and
shall not propose to declare or pay any dividends on or make other
distributions in respect of any of their capital stock or partnership or other
equity interests, except for partnership and limited liability company
distributions in the ordinary course of business consistent with past
practice, split, combine or reclassify any of its capital stock or partnership
or other equity interests or issue or authorize the issuance of any other
securities in respect of, in lieu of or in substitution for shares of their
capital stock or partnership or other equity interests, or repurchase or
otherwise acquire any shares of its capital stock or partnership or other
equity interests or rights to acquire any shares of their capital stock or
partnership or other equity interests except for repurchases of Koll Common
under the Koll Plans which in the aggregate are not material.
 
  6.3 Issuance of Securities. Except as set forth on Schedule 6.3, Koll, Subs,
Investment Entities and 50% JVs shall not issue, deliver or sell or authorize
or propose the issuance, delivery or sale of, or purchase or propose the
purchase of, any shares of its capital stock or partnership or other equity
interests of any class or securities convertible into, or rights, warrants or
options to acquire, any such shares or interests or other convertible
securities, other than the issuance of Koll Common upon the exercise of the
Koll Options in accordance with their present terms. Neither Koll nor its
Board of Directors shall take any action to change the exercise price or any
other term of presently outstanding Koll Options. Notwithstanding the
foregoing, Koll may accelerate the vesting schedules of Koll Options and
restricted stock outstanding on the date hereof and may terminate repurchase
rights and rights of first refusal given in connection therewith.
 
  6.4 Governing Documents. Neither Koll nor Subs shall amend or agree to amend
their charter documents or Bylaws.
 
                                     1-23

  6.5 No Solicitations. Except as set forth on Schedule 6.5, Koll and Subs
shall not, directly or indirectly, through any officer, director, employee or
agent (including any investment banker, financial advisor, attorney,
accountant or other representative or agent) or otherwise, solicit, initiate
or encourage inquiries or the submission of proposals or offers from any Third
Party relating to any acquisition or purchase of all or substantially all of
the business, properties or assets of, or any equity interest in, Koll or any
of the Subs or any merger, consolidation, business combination or similar
transaction, other than pursuant to this Agreement involving Koll or any of
the Subs (an "Acquisition Transaction"), other than the sale by Koll Dove
Global Disposition Services, L.L.C., of certain assets to which it takes title
in the ordinary course of its auction business consistent with past practice
or participate in any discussions or negotiations regarding, or furnish to any
other person any confidential information with respect to, or otherwise
cooperate in any way with, or participate in, facilitate or agree to endorse
or encourage, any effort or attempt by any other person to do or seek any of
the foregoing. Koll shall (i) promptly advise CBC orally and in writing of any
such offer and of any inquiries or proposals of or contacts with third parties
for any Acquisition Transaction involving Koll or any of the Subs and (ii)
immediately inform CBC of the details of such offer, proposal, inquiry or
contact and provide CBC copies of any written material related thereto, and
(iii) not accept (nor shall Koll's Board of Directors or any committee thereof
recommend) any such proposal or offer.
 
  6.6 No Acquisitions or Investments.
 
  (a) Except as set forth on Schedule 6.6, Koll and Subs shall not acquire or
agree to acquire by merging or consolidating with, or by purchasing a
substantial portion of the assets or stock of, or by any other manner, any
business or any corporation, partnership, association or other business
organization or division thereof.
 
  (b) Except as set forth on Schedule 6.6, Koll and Subs shall not purchase or
otherwise acquire (through a joint venture or otherwise) or agree to purchase
or otherwise acquire more than a five percent (5%) interest in the assets,
equity or business of any other corporation, partnership, trust, limited
liability company or other entity.
 
  6.7 No Dispositions. Except as set forth on Schedule 6.7, Koll and Subs
shall not and shall not agree to sell, lease or otherwise dispose of any of
its assets that are material, individually or in the aggregate, to Koll and
Subs, taken as a whole, except in the ordinary course of business consistent
with prior practice (which includes the sale by Koll Dove Global Disposition
Services, L.L.C., of certain assets to which it takes title in the ordinary
course of its auction business consistent with past practice).
 
  6.8 Indebtedness. Koll and Subs shall not and shall not agree to incur any
indebtedness for borrowed money (other than in connection with acquisitions
permitted under Section 6.6 or under credit facilities existing as of the date
hereof relating to working capital loans made in the ordinary course of
business consistent with past practice and working capital advances made by
Koll or a Sub to a Sub, Investment Entity or 50% JV in the ordinary course of
business, consistent with past practice) or guarantee any such indebtedness or
issue or sell any debt securities of Koll or Subs or guarantee any debt
securities of others.
 
  6.9 Other Actions. Koll and Subs shall not permit any of their officers,
directors, employees or agents to take any action that would, or reasonably
would be expected to, result in any of its representations and warranties set
forth in this Agreement being or becoming untrue in any material respect, or
in any of the conditions set forth in Article 11 not being satisfied.
 
  6.10 Advice of Changes. Koll and Subs shall confer on a regular basis with
CBC, report on operational matters and promptly advise CBC orally and in
writing of any change or event having, or which, insofar as can reasonably be
foreseen, could have, a Material Adverse Effect or which would cause or
constitute a material breach of any of the representations, warranties or
covenants of Koll or Subs contained herein. Except where prohibited by
applicable statues and regulations, Koll and Subs shall promptly provide CBC
(or its counsel) with copies of all filings made by Koll and Subs with any
state or federal governmental entity in connection with this Agreement or the
transactions contemplated hereby.

<PAGE>
 
  6.11 Accounting Methods. Koll and Subs shall not change their methods of
accounting in effect at December 31, 1996, except as required by changes in
GAAP as concurred in by Koll's independent auditors and except to change their
fiscal year to conform with that of CBC.
 
  6.12 Tax-Free Reorganization Treatment. Koll and Subs shall not take or
cause to be taken any action, whether before or after the Effective Time, that
would disqualify the Merger as a reorganization under Sections 368(a)(1)(A)
and 368(a)(2)(E) of the Code.
 
  6.13 Compensation; Benefit Plans.
 
  (a) Except as previously disclosed in writing to CBC prior to the execution
of this Agreement, Koll and Subs will not adopt or amend in any material
respect any collective bargaining agreement with employees, enter into, adopt,
amend or terminate any benefit plan or any other employee benefit plan or any
agreement, arrangement, plan or policy between such party and one or more of
its directors or officers, in each case so as to materially increase benefits
thereunder, increase the compensation or fringe benefits of any officer or
employee who earned $100,000 or more in total compensation during the twelve-
month period ended March 31, 1997 ("Key Employee") or any director or provide
any other benefit not required by any plan or arrangement in effect as of the
date hereof (including, without limitation, the granting of stock options,
stock appreciation rights, restricted stock, restricted stock units or
performance units or shares) other than to accelerate the vesting schedule of
Koll options outstanding on the date hereof or enter into any contract,
agreement, commitment or arrangement to do any of the foregoing, except (with
respect to employees who are not Key Employees or directors only) for normal
increases and benefit changes in the ordinary course of business consistent
with past practice or bonuses paid under policies consistent with past
practice that, in the aggregate, do not result in a material increase in
benefits or compensation expense to such party, create or amend any stock plan
or grant any equity based award pursuant to any stock plan or otherwise or
enter into or renew any contract, agreement, commitment or arrangement
providing for the payment to any Key Employee or director of such party of
compensation or benefits contingent, or the terms of which are materially
altered, upon the occurrence of any of the transactions contemplated by this
Agreement, except for contracts, agreements, arrangements or commitments which
create an at-will employment relationship with an employee (other than a
director) or which provide for a severance payment to such an employee equal
to or less than eight months base salary for such employee, based on such
employee's current average monthly base salary.
 
  (b) Schedule 6.13 contains a complete and correct list of all bonuses or
other compensation (not accrued on Koll's March 31, 1997 balance sheet or
included in the "Bonus Basket" (as defined below)) other than base salary (and
standard benefits), brokerage commissions and regular periodic payments (other
than bonuses) to agents and independent contractors in the ordinary course of
business consistent with past practice that may be paid to any officer,
employee, agent, director or independent contractor of Koll between the date
hereof and the Effective Time and the name of the individual designated to
receive such bonus or other compensation. Koll covenants and agrees that
between the date hereof and the Effective Time, it will not pay any bonus or
other compensation (other than base salary (and standard benefits), brokerage
commissions and regular periodic payments (other than bonuses) to agents and
independent contractors in the ordinary course of business consistent with
past practice) to any of its officers, directors, employees, agents or
independent contractors other than bonuses and other compensation set forth on
Schedule 6.13, accrued on Koll's March 31, 1997 balance sheet or included in
the Bonus Basket. In no event will the aggregate amount of all such bonuses
paid or payable between the date hereof and the Effective Time exceed the sum
of (i) the amount accrued on Koll's March 31, 1997 balance sheet plus (ii) the
aggregate amount shown on Schedule 6.13 plus (iii) the amount of the Bonus
Basket. For purposes of this Section 6.13(b) the "Bonus Basket" shall be an
amount not to exceed $500,000 and shall be accrued on Koll's June 30, 1997
balance sheet together with any bonus amounts accrued on Koll's March 31, 1997
balance sheet which are not paid between March 31, 1997 and June 30, 1997.
 
  6.14 Liability Limitations. (i) The aggregate amount of indebtedness owed by
Koll, Subs, the Investment Entities and 50% JVs directly or indirectly
(including letters of credit), to Banks, savings and loans, thrifts and
similar institutions ("Bank Indebtedness") shall not exceed $47,375,000 as of
the Effective Time (exclusive of
 
                                     1-25
<PAGE>
 
(A) indebtedness of Investment Entities or Subs which serve as investment
vehicles for clients of Koll or of Subs which indebtedness is secured solely
by the assets of such Investment Entity or Subs and (B) indebtedness under
those certain two revolving lines of credit by and between Comerica Bank and
Koll Dove Global Disposition Services LLC, not to exceed $600,000 under that
line of credit to be used for financing pre-auction expenses and not to exceed
$400,000 under that line of credit to be used for issuing standby letters of
credit) and the amounts owed for subcategories within the $47,375,000 shall
not exceed $2,375,000 with respect to a letter of credit securing the payment
of the balance of the purchase price with respect to the acquisition of CBS,
$3,750,000 with respect to financing the "Convenience Store Project" (but with
no obligation to do such project) and $41,250,000 for all other subcategories,
(ii) the aggregate amount loaned by Koll, Subs, each Investment Entity and
each 50% JV to employees, Affiliates and related persons shall not exceed the
amount so loaned on March 31, 1997 (excluding loans to entities with respect
to which Koll, a Sub, an Investment Entity or a 50% JV has an investment
management relationship for the purpose of purchasing real property and
working capital advances between wholly-owned Subs), and (iii) the aggregate
amount owed by Koll, Subs, Investment Entities and 50% JVs (other than any
amount which is reflected in Bank Indebtedness, which for purposes of this
clause (iii) shall include all amounts payable pursuant to the CC&F redemption
agreement referred to in Section 11.2(j)) with respect to the purchase of
businesses (whether structured as an asset purchase or a stock purchase) shall
not exceed the amount owed as of the date hereof (exclusive of earnouts and
profit participations). Notwithstanding anything to the contrary contained
herein, a breach of clause (i) this Section shall not give rise to any cause
of action for damages, but only a purchase price adjustment as set forth in
Section 2.3(d), except to the extent a breach of clause (i) of this Section
results in a Material Adverse Effect on Koll, in which case CBC shall have the
right to terminate this agreement.
 
  6.15 Certain Payments. Koll and its Subs will make all salary, benefit,
bonus and minority interest payments on a timely basis consistent with past
practice and any delay in making any such payment which is not consistent with
past practice and which causes the amount shown on the consolidated balance
sheet of Koll and its Subs as of the last day of the month preceding the
Closing to increase by over $250,000 from what it would have been if past
practice had been observed shall be treated as an increase in Bank
Indebtedness for purposes of Sections 2.3(c) and (d).

Effective Time, CBC shall and shall cause its Subsidiaries to comply with the
following:
 
  8.1 Ordinary Course. Each of CBC and each of its Subsidiaries shall carry on
their business in the usual, regular and ordinary course, including the
payment of all state and federal taxes, in substantially the same manner as
heretofore conducted and, to the extent consistent with such businesses, use
all commercially reasonable efforts consistent with past practice and policies
to preserve intact its present business organization, keep available the
services of its present officers, key employees, agents and representatives
and preserve its goodwill and relationships with existing and potential
customers, employees, independent contractors, clients, suppliers, and others
with whom business relationships exist to the end that its goodwill and
ongoing businesses shall be unimpaired at the Effective Time. Neither CBC nor
any of its Subsidiaries shall enter into any agreement which would prevent CBC
from consummating the transactions contemplated hereby.
 
  8.2 Dividends; Changes in Stock. Each of CBC and its Subsidiaries that are
not wholly-owned shall not and shall not purpose to declare or pay any
dividends on or make other distributions in respect of any of its capital
stock, split, combine or reclassify any of its capital stock or issue or
authorize the issuance of any other securities in respect of, in lieu of or in
substitution for shares of their capital stock, or repurchase or otherwise
acquire any shares of its capital stock or rights to acquire any shares of
their capital stock. Notwithstanding the foregoing, nothing contained in this
Agreement shall restrict (i) CBC from paying dividends on its Preferred Stock
or (ii) CBC or any of its Subsidiaries from purchasing stock or other equity
interest in a direct or indirect wholly-owned Subsidiary.
 
  8.3 Governing Documents. CBC shall not amend or agree to amend its charter
documents or Bylaws other than to change the authorized number of its
directors.
 
  8.4 No Acquisitions. CBC and Subsidiaries shall not acquire or agree to
acquire by merging or consolidating with, or by purchasing a substantial
portion of the assets of, or by any other manner, any business or any
corporation, partnership, association or other business organization or
division thereof, or otherwise acquire or agree to acquire any assets which
individually or in the aggregate involve total consideration in excess of
$12,500,000.
 
  8.5 No Dispositions. CBC and its Subsidiaries shall not sell, issue, lease
or otherwise dispose of any portion of its capital stock or assets that is

ordinary course of business consistent with prior practice and upon the
exercise of CBC options or other securities convertible into CBC Common or
enter into any merger, exchange, consolidation or other agreement not
permitted by Section 8.4, or enter into any agreement which would prevent CBC
from completing the transactions contemplated herein.
 
  8.6 Other Actions. CBC and its Subsidiaries shall not permit any of their
officers, directors, employees or agents to take any action that would, or

                                     1-27
<PAGE>
 
  8.7 Accounting Methods. CBC and its Subsidiaries shall not change their
methods of accounting in effect at December 31, 1996, except as required by
changes in GAAP as concurred in by CBC's independent auditors.
 
  8.8 Indemnification of Directors and Officers.
 
  (a) CBC and Group shall indemnify and hold harmless, to the fullest extent
permitted by applicable law as it presently exists or may hereafter be
amended, any person who was or is made or is threatened to be made a party or
is otherwise involved in any action, suit or proceeding, whether civil,
criminal, administrative or investigative (a "Proceeding") by reason of the
fact that he, or a person for whom he is the legal representative, is or was a
director or officer of Koll or any Sub prior to the Effective Time (an
"Indemnified Agent"), against all liability and loss suffered and expenses
(including attorneys' fees) reasonably incurred by such person. CBC shall not
be required to indemnify and hold harmless a person in connection with a
Proceeding (or part thereof) (i) initiated by such person unless the
Proceeding (or part thereof initiated by such person) was authorized by the
Board of Directors or (ii) in which it is determined that such Indemnified
Agent had actual knowledge at or prior to the Closing of any fact, event or
circumstance which would have constituted a breach of this Agreement.
 
  (b) The right to indemnification conferred by this Article 8 shall be
presumed to have been relied upon by the Indemnitee and shall be enforceable
as a contract right. CBC may enter into contracts to provide individual
Indemnitees with specific rights of indemnification to the fullest extent
permitted by applicable law and may create trust funds, grant security
interests, obtain letters of credit or use other means to ensure the payment
of such amounts as may be necessary to effect the rights provided in this
Article 8 or in any such contract.
 
  (c) Except for any Proceeding described in the last sentence of Section
8.8(a), upon making a request for indemnification, the Indemnitee shall be
presumed to be entitled to indemnification under this Section 8.8 and CBC
shall have the burden of proof to overcome that presumption in reaching any
contrary determination. Such indemnification shall include the right to
receive payment in advance of any reasonable expenses incurred by the
Indemnitee in connection with any Proceeding (other than a Proceeding
described in the last sentence of Section 8.8(a)) consistent with the
provisions of applicable law.
 
  (d) If any Proceeding shall be brought or asserted under this Section 8.8,
the Indemnified Agent shall give prompt written notice of such action or claim
to the Indemnifying Party who shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Agent and the
payment of all expenses; except that any delay or failure to so notify the
Indemnifying Party shall relieve the Indemnifying Party of its obligations
hereunder only to the extent, if at all, that it is prejudiced by reason of
such delay or failure. The Indemnified Agent shall have the right to employ
separate counsel in any of the foregoing Proceedings and to participate in the
defense thereof, but the fees and expenses of such counsel shall be at the
expense of the Indemnified Agent. In the event that the Indemnifying Party,
within ten days after notice of any such action or claim, fails to assume the
defense thereof, the Indemnified Agent shall have the right to undertake the
defense, compromise or settlement of such Proceeding for the account of the
Indemnifying Party and the Indemnifying Party shall use reasonable efforts to
assist in the defense of such matter, subject to the right of the Indemnifying
Party to assume, at its expense, the defense of such Proceeding with counsel
satisfactory to the Indemnified Agent at any time prior to the settlement,
compromise or final determination thereof, and provided that CBC shall not be
liable for any settlement of any claim effected without its written consent,
which shall not be unreasonably withheld. Anything in this Section 8.8 to the
contrary notwithstanding, the Indemnifying Party shall not, without the
Indemnified Agent's prior written consent, settle or compromise any action or
claim or consent to the entry of any judgment with respect to any Proceeding
for anything other than money damages paid by the Indemnifying Party. The
Indemnifying Party may, without the Indemnified Agent's prior written consent,
settle or compromise any such Proceeding or consent to entry of any judgment
with respect to any such action or claim that requires solely the payment of
money damages by the Indemnifying Party and that includes as an unconditional
term thereof the release by the claimant or the plaintiff of the Indemnified
Agent from all liability with respect to such Proceeding. The Indemnified
Agents as a group may retain only one law firm to represent them with respect
to each such matter, at CBC's and Group's expense, unless there is, under
applicable standards of conduct, a conflict on any significant issue between
any two or more Indemnified Agents or between an
 
                                     1-28
<PAGE>
 
Indemnified Agent and an Indemnifying Party which is a co-defendant in the
proceeding and is represented by the same counsel. Notwithstanding the
foregoing, nothing in this Section 8.8(b) shall be construed to require any
Indemnifying Party to indemnify any Indemnified Agent for any Unindemnified
Liability.
 
  (e) This Section 8.8 is intended for the benefit of the Indemnified Agents
(each of whom shall be entitled to enforce this Section 8.8 against CBC) and
shall be binding upon all successors and assigns to CBC. This Section 8.8
shall survive the Effective Time and continue in full force and effect for a
period of six years after the Effective Time; provided, that, in the event any
claim is asserted or made within such six year period, all rights to
indemnification in respect of any such claim shall continue until final
disposition of such claim.
 
  (f) If this Section 8.8 is found to be unenforceable under applicable law or
materially limited by a contract to which CBC or Group is a party, CBC and
Group shall indemnify the Indemnified Agents in accordance with the terms of
their current indemnity agreements with Koll and the current Bylaws and
Certificate of Incorporation of Koll.
 
  8.9 Tax Treatment. CBC and its Subsidiaries shall not take or cause to be
taken any action, whether before or after the Effective Time, that would
disqualify the Merger as a reorganization under Sections 368(a)(1)(A) and
368(a)(2)(E) of the Code. CBC and Acquisition Corporation agree to make such
reasonable representations as may be requested by Koll or the Koll
Shareholders in connection with the opinion to be delivered by counsel for
Koll pursuant to Section 11.3(g).
 
  8.10 Listing on NASDAQ. CBC shall take all appropriate actions for listing
the shares of CBC Common to be received in the Merger on NASDAQ.
 
  8.11 Advice of Changes. CBC shall confer on a regular basis with Koll,
report on operational matters and promptly advise Koll orally and in writing
of any change or event having, or which, insofar as can reasonably be
foreseen, could have, a Material Adverse Effect or which would cause or
constitute a material breach of any of the representations, warranties or
covenants of CBC contained herein. Except where prohibited by applicable
statues and regulations, CBC shall promptly provide Koll (or its counsel) with
copies of all filings made by CBC with any state or federal governmental
entity in connection with this Agreement or the transactions contemplated
hereby.
 
                                   ARTICLE 9
 
    ADDITIONAL AGREEMENTS RELATING TO THE FORM S-4 AND THE PROXY STATEMENT
 
  As promptly as practicable after the date hereof, CBC, with the cooperation
of Koll, shall prepare and file the Form S-4 with the SEC, in which the Proxy
Statement will be included as part of a prospectus. CBC shall use its best
efforts to promptly respond to comments from the SEC and to file amendments to
the Form S-4 in order to have the Form S-4 declared effective under the
Securities Act as promptly as practicable after such filing. CBC shall also
take any action required to be taken under any applicable state securities or
blue sky laws in connection with the issuance of the CBC Common in the Merger.
Koll shall use its best efforts to furnish to CBC all information concerning
Koll and the holders of its outstanding securities as may be reasonably
requested in connection with any action contemplated by this Article 9. CBC
will promptly notify Koll and provide Koll with copies of any correspondence
between CBC and its representatives, on the one hand and the SEC, its staff or
any state securities administrators on the other.

                             ADDITIONAL AGREEMENTS
 
  10.1 Access to Information. Koll shall afford to CBC and shall cause its
independent accountants to afford to CBC, and its accountants, counsel and
other representatives, reasonable access during normal business hours during
the period prior to the Effective Time to all of Koll and Sub's properties,
books, contracts, commitments and records and to the independent accountants
reasonable access to the audit work papers and other records of Koll's
accountants. During such period, Koll shall use reasonable efforts to furnish
promptly to CBC a copy of each report, schedule and other document filed or
received by Koll during such period pursuant to the requirements of federal
and state securities laws and all other information concerning the business,
properties and personnel of Koll and Subs as CBC may reasonably request. CBC
will not use such information for purposes other than this Agreement and will
otherwise hold such information in confidence (and CBC will cause its
consultants and advisors also to hold such information in confidence) pursuant
to the terms of that certain Confidentiality Agreement, dated as of March 21,
1997, by and among CBC, Koll, FS, Apollo and Donald M. Koll until such time as
such information otherwise becomes publicly available, and in the event of
termination of this Agreement for any reason CBC shall promptly return, or
cause to be returned, to the disclosing party all documents obtained from Koll
and Subs, and any copies made of such documents, extracts and copies thereof.
CBC shall provide to Koll and its counsel, independent accountants and other
representatives, access to such information regarding CBC as, in CBC's sole
opinion, would customarily be provided to an underwriter in connection with a
Registration Statement on Form S-1 covering shares of CBC Common or attached
as an exhibit thereto.
 
  10.2 Legal Conditions to the Merger. Each party will take and will cause its
respective Subsidiaries to take all reasonable actions necessary to comply
promptly with all legal requirements which may be imposed on such party with
respect to the Merger (including furnishing all information required under the
HSR Act) and will promptly cooperate with and furnish information to the other
party in connection with any such requirements imposed upon such other party
or any Subsidiary of such other party in connection with the Merger. Each
party will take, and will cause its respective Subsidiaries to take, all
reasonable actions to obtain (and to cooperate with the other party and its
Subsidiaries in obtaining) any consent, authorization, order or approval of,
or any exemption by, any governmental authority, or other third party,
required to be obtained or made by such party or its Subsidiaries (or by the
other party or its Subsidiaries) in connection with the Merger or the taking
of any action contemplated thereby or by this Agreement. For purposes of this
Section 10.2 only, Koll will not be considered a Subsidiary of FS.
 
  10.3 Koll Stockholders' Approval. Koll agrees to submit this Agreement, the
Certificate of Merger and any related matters to its stockholders for
approval, all as provided by law and its Certificate of Incorporation and
Bylaws, at a meeting which will be held as soon as practicable after the date
hereof. The Board of Directors of Koll has unanimously recommended to the Koll
stockholders that such stockholders approve the transactions contemplated by
this Agreement and the Certificate of Merger.
 
  10.4 CBC Stockholders' Approval. CBC agrees to submit this Agreement, the
Certificate of Merger and any related matters to its stockholders for
approval, by means of the Proxy Statement, all as provided by law and its
Certificate of Incorporation and Bylaws, at a meeting which will be held as
soon as practicable after the date hereof. The Board of Directors of CBC has
unanimously recommended to the CBC stockholders that such stockholders approve
the transactions contemplated by this Agreement and the Certificate of Merger.
 
  10.5 Dissenting Shares. As promptly as practicable after the date of the
Koll Stockholders' Meeting and prior to the Closing Date, Koll shall furnish
CBC with the name, address and number of Dissenting Shares owned by each
Dissenting Stockholder.
 
  10.6 Communications. Between the date hereof and the Effective Time, neither
Koll nor CBC will (i) furnish any communication to its stockholders, any
analysts, the press or to the public generally if the subject matter thereof
relates to the other party or to the transactions contemplated by this
Agreement or the Certificate
 
                                     1-30
<PAGE>
 
of Merger without the prior approval of the other party as to the content
thereof, which approval shall not be unreasonably withheld (unless such
disclosure is nonetheless required in the opinion of counsel), and (ii)
respond to all inquiries from stockholders, analysts, the press or the public
generally regarding the other parties hereto or transactions contemplated by
this Agreement or the Certificate of Merger with "No comment", subject, in
each case, to each party's compliance with applicable law. Notwithstanding the
foregoing, Koll and CBC may communicate with their respective customers and
clients on a "need-to-know" basis and provided that each such client or
customer agrees to keep the information conveyed confidential.
 
  10.7 Delivery of Stock Certificates. CBC will promptly issue and deliver as
and when required by the provisions of this Agreement, the certificates
representing the shares of CBC Common into which the shares of Koll Common
outstanding immediately prior to the Effective Time shall have been converted
as provided in this Agreement.
 
  10.8 Update to Disclosures.
 
  (a) Without limiting any party's right to rely on the representations and
warranties as of the date of this Agreement, each party shall provide the
others with updates to the disclosures provided or made available to the other
as to material facts which arise between the date of this Agreement and the
Closing Date and which, if they had occurred and been known prior to the date
of this Agreement, would have been required to have been disclosed in order to
make the representations and warranties contained in Articles 3, 4 or 5, as
applicable, true and correct as of the date of this Agreement.
 
  (b) Koll will advise CBC as soon as reasonably practicable if any customers
from whom it receives annualized revenue of more than $250,000 indicates that
it is either materially dissatisfied with services being provided by Koll or
any Sub or the proposed Merger.
 
  10.9 Good Faith. Each party shall act in good faith in an attempt to cause
all the conditions precedent to its obligations under this Agreement to be
satisfied. Each party will act in good faith and take all reasonable action
within its capability necessary to render accurate as of the Effective Time
its representations and warranties contained in this Agreement.
 
  10.10 State Statutes. If any state takeover law shall become applicable to
the transactions contemplated by this Agreement, CBC and its Board of
Directors or Koll and its Board of Directors, as the case may be, shall use
their reasonable best efforts to obtain such approvals and take such actions
as are necessary so that the transactions contemplated by this Agreement may
be consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise to minimize the effects of such state takeover law on
the transactions contemplated by this Agreement.
 
  10.11 Affiliates. At least ten days prior to the date of the Koll
Stockholders' Meeting, Koll shall deliver to CBC a list of names and addresses
of those persons who were, in Koll's reasonable judgment, at the record date
for the Koll Stockholders' Meeting, "affiliates" of Koll within the meaning of
Rule 145 (each such person, together with the persons identified below, an
"Affiliate") of the rules and regulations promulgated by the SEC under the
Securities Act ("Rule 145"). Koll shall provide CBC such information and
documents as CBC shall reasonably request for purposes of reviewing such list.
There shall be added to such list the names and addresses of any other person
(within the meaning of Rule 145) that CBC reasonably identifies (by written
notice to Koll within three Business Days after CBC's receipt of such list) as
being a person who may be deemed to be an Affiliate of Koll within the meaning
of Rule 145; provided, however, that no such person identified by CBC shall be
added to the list of Affiliates of Koll if CBC shall receive from Koll, on or
before the Effective Time, an opinion of counsel reasonably satisfactory to
CBC to the effect that such person is not an Affiliate. Koll shall use its
best efforts to deliver or cause to be delivered to CBC, prior to the
Effective Time, from each of the Affiliates of Koll identified in the
foregoing list (as the same may be supplemented as aforesaid), agreements
(collectively, the "Koll Affiliate Agreements") substantially in the form
attached to this Agreement as Exhibit D. CBC and Acquisition Corporation shall
be entitled to issue appropriate stop transfer instructions to the transfer
agent for CBC Common Stock, consistent with the terms of such Affiliate
Agreements, whether or not such Affiliate Agreements are actually delivered to
CBC.
 
                                     1-31
<PAGE>
 
  10.12 Koll Options.
 
  (a) Substitute CBC Options. Subject to the provisions of this Section 10.12,
at and as of the Effective Time, CBC will substitute a CBC Option for each
Koll Option outstanding under a Koll option plan held by an individual who is
a director, employee or consultant of Koll or Subs immediately prior to the
Effective Time. In addition, following the Effective Time, each such
individual entitled to receive a CBC Option will receive a number of Warrants
equal to the Warrant Exchange Ratio multiplied by the number of shares of Koll
Common into which such Koll Option is exercisable. Each and every CBC Option
so substituted by CBC under this Agreement will continue to have, and be
subject to, substantially the same terms and conditions set forth in the Koll
option plans and/or in the other documents governing such Koll Option
immediately prior to the Effective Time, except that such CBC Option will be
exercisable for that number of whole shares of CBC Common equal to the product
of the number of shares of Koll Common that were purchasable under such Koll
Option immediately prior to the Effective Time multiplied by the Stock
Exchange Ratio, rounded down to the nearest whole number of shares of CBC
Common, and the per share exercise price for the shares of CBC Common issuable
upon exercise of such CBC Option will be equal to the quotient determined by
dividing the exercise price per share of Koll Common at which such Koll Option
was exercisable immediately prior to the Effective Time by the Stock Exchange
Ratio, and rounding the resulting exercise price up to the nearest whole cent.
The parties shall use their best efforts to provide that the transactions
contemplated by this Agreement will not terminate or accelerate any
substituted CBC Option or any right of exercise, vesting or repurchase
thereunder with respect to shares acquired upon exercise of such option other
than Koll Options intentionally accelerated by Koll in contemplation of the
Merger. The right to receive a substituted CBC Option issued pursuant to any
documents governing such substituted CBC Option may not be assigned or
transferred in any manner except by operation of law, by will or by the laws
of descent. Any attempted assignment in violation of this Section shall be
void. As of the Effective Time, CBC shall have reserved for issuance and
continue to maintain shares of CBC Common sufficient to issue the required
shares of CBC Common pursuant to the exercise of the substituted CBC Options
after the Effective Time. CBC shall use its reasonable best efforts to cause
any CBC Options issued in substitution for existing Koll Options and any
Warrants issued in respect of such Koll Options pursuant to this Section 10.12
to be covered by an effective Registration Statement under the Securities Act
of 1933, as amended (the "Securities Act") at or before the Effective Time.
CBC covenants and agrees that on or prior to the Closing Date, CBC's Board of
Directors (or a committee thereof composed solely of two or more non-employee
directors (as defined in Rule 16b-3(b)(3)(i) of the Exchange Act)) shall have,
in accordance with Rule 16b-3(d)(1) of the Exchange Act, approved the grant of
such substituted CBC Options, identified the individuals receiving such CBC
Options and identified which of such individuals are or following the Merger
will be directors or officers of CBC subject to Section 16(b) of the Exchange
Act.
 
  (b) Documentation. At the Closing, CBC shall issue to each holder of an
outstanding Koll Option a document evidencing the substitution of a CBC Option
for such Koll Option pursuant to this Section, in a form mutually satisfactory
to the parties hereto.
 
  (c) Reallocation of Warrants. Following the Effective Time and until the
Warrants become exercisable, if any CBC Option substituted for a Koll Option
expires or is terminated without being exercised, all Warrants issued in
respect of such option shall be forfeited by the holder thereof. At such time
as the Warrants become exercisable, all Warrants forfeited pursuant to the
immediately preceding sentence shall be reallocated among those individuals
who held shares of Koll Common or Koll Options as of the date hereof (as set
forth on Schedule 3.2(c)) (each a "Reallocation Holder" and collectively, the
"Reallocation Holders") pro rata based on the aggregate number of shares of
the CBC Common issued and shares of CBC Common underlying CBC Options issued
to each Reallocation Holder pursuant hereto divided by the total number of
shares of CBC Common issued and shares of CBC Common underlying CBC Options
issued to all Reallocation Holders pursuant hereto.
 
  10.13 Composition of CBC Board. Following the Effective Time, so long as the
Koll Shareholders who are signatories to this Agreement hold shares equal to
60% of the shares originally issued to them pursuant to this Agreement (as
adjusted to reflect stock splits, reverse stock splits, reclassifications,
recapitalizations and
 
                                     1-32
<PAGE>
 
similar events) CBC will cause three individuals selected by the Koll
Shareholders (the "Majority Koll Shareholders") holding a majority of the
shares of CBC Common received in the Merger and then held by the Koll
Shareholders and reasonably satisfactory to the Corporate Governance Committee
of CBC's Board of Directors to be nominated for election to CBC's Board of
Directors. For so long as they are employed or engaged by CBC two of those
individuals will be RW and DMK. In addition to the three directors referred to
above, following the Effective Time and until the election of directors to
CBC's Board of Directors first following the Effective Time, CBC will cause
one individual selected by AP KMS II, LLC and reasonably satisfactory to the
Corporate Governance Committee of CBC's Board of Directors to be nominated to
CBC's Board of Directors. In the event that the Koll Shareholders no longer
hold shares equal to 60% of the shares originally issued to them pursuant to
this Agreement (as adjusted to reflect stock splits, reverse stock splits,
reclassifications, recapitalizations and similar events), so long as FS owns
60% of the shares originally issued to FS pursuant to this Agreement (as
adjusted to reflect stock splits, reverse stock splits, reclassifications,
recapitalizations and similar events) CBC will cause one individual selected
by FS and reasonably satisfactory to CBC to be nominated for election to CBC's
Board of Directors. Upon their election to CBC's Board of Directors, CBC shall
enter into an indemnity agreement with the directors described above in the
form which CBC's current directors and CBC are parties to.
 
  10.14 Agreements of Donald M. Koll. DMK hereby agrees (i) to the assignment
to CBC of the License Agreement and the Noncompetition Agreements and (ii) to
cause KHC to enter into the Voting Agreement and to otherwise comply with the
provisions of Section 7.3.
 
  10.15 Tax Treatment. Each party hereto agrees to take such further actions
consistent with the terms of this Agreement and applicable law as may be
reasonably necessary to cause the Merger to be treated as a reorganization
under Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code, including but not
limited to preparing appropriate returns, filings and reports consistent with
the treatment of the Merger as such a reorganization, provided, however, that
CBC shall not be required to take any action which, in the sole judgment of
CBC, would incur or result in it incurring a material economic cost.
 
  10.16 Reservation of Shares. CBC will at all times reserve and keep
available out of its authorized but unissued shares of CBC Common such number
of shares as is issuable upon exercise of all outstanding Warrants, CBC
Options or other rights to subscribe for or purchase CBC Common.
 
  10.17 K/B Opportunity Funds. Koll will do the following with respect to K/B
Opportunity Fund I, K/B Opportunity Fund II and K/B Opportunity Fund III
(individually a "K/B Fund" and collectively the "K/B Funds"):
 
  (a) Prior to the Closing, Koll will cause the general partner of each K/B
Fund to advise each limited partner or other investor in such K/B Fund of the
impending merger between Koll and CBC and that the general partner intends to
engage Group as a listing broker where it is the best choice as listing broker
and where Group is not the listing broker to pay it an appropriate commission
only if and when it provides the buyer for any property sold by such K/B Fund.
After the Closing, the Koll Shareholders will use their reasonable best
efforts to cause each K/B Fund to engage Group as the exclusive listing broker
for the disposition of such fund's properties or, where that is not feasible,
to engage Group as the listing broker on a property by property basis.
 
  (b) In the event at any time prior to January 1, 2003, a K/B Fund is unable
to pay Group a commission (whether as listing or procuring broker) because one
or more limited partners in a K/B Fund has objected to such payment, and such
K/B Fund is unable to resolve the objection within 60 days so that Group may
receive its commission if it is the listing or procuring broker, then the Koll
Shareholders will owe to Group the applicable commission with respect to such
property as determined from Schedule 10.17. In the event the partnership
agreement of any K/B Fund is amended in a legally binding manner to permit
Group to be paid commissions with respect to all of the properties of such
Fund this Section 10.17 shall not apply to such Fund. To the extent the
limited partners of and any other investors in any K/B Fund consent (in a
legally binding manner) to Group
 
                                     1-33
<PAGE>
 
receiving commissions with respect to one or more properties or waive (in a
legally binding manner) any prohibition on Group receiving commissions on one
or more properties then this Section 10.17 shall not apply to such properties.
 
  (c) The Koll Shareholders shall have no obligation to pay a commission with
respect to any property transferred to a Real Estate Investment Trust as to
which a Koll Affiliate is an asset manager, a sub asset manager or a property
manager (an "Affiliated REIT") or to the extent Group has received commissions
with respect to the sale of properties by the K/B Funds (whether from the K/B
Funds, the Koll Shareholders or a third party) equal to half of the maximum
commission applicable to "Eligible Properties" as determined pursuant to
Schedule 10.17. The term Eligible Properties means the properties listed on
Schedule 10.17 other than (i) any such properties listed as "Non-Included
Properties," (ii) any properties transferred, prior to January 1, 2003, to an
Affiliated REIT and (iii) any property sold prior to January 1, 2003 by such
fund where throughout the period such property has been offered for sale,
Group has the right or a full and fair competitive opportunity to receive a
commission from its sale if Group were the listing or procuring broker. The
Koll Shareholders may pay the aggregate amount, if any, due to Group by the
Koll Shareholders pursuant to this Section 10.17 at any time, up to and
including December 31, 2002, at which date all amounts due hereunder must be
paid. At such time as the Koll Shareholders pay the amounts due hereunder, if
any, in addition to the amounts due calculated in accordance with Schedule
10.17, the Koll Shareholders shall also pay interest on such amounts, at a
rate of eight percent (8%), compounded annually, from the date an obligation
is incurred hereunder until the date such payment is made. Any commissions
collected by Group with respect to the disposition of Eligible Properties in
excess of the amounts set forth on Schedule 10.17 with respect to a specified
K/B Fund shall be applied to reduce any amounts thereafter payable by the Koll
Shareholders with respect to the other K/B Funds.
 
  (d) Notwithstanding anything else contained in this Agreement, the
provisions of this Section 10.17 shall survive the consummation of the Merger
and the Effective Time and shall continue until the earlier of (i) the Koll
Shareholders have satisfied all their obligations under Subsections (b) and
(c) hereof, (ii) Group has received commissions with respect to the sale of
properties by the K/B Funds (whether from the K/B Funds, the Koll Shareholders
or a third party) equal to half of the maximum commission applicable to
"Eligible Properties" as determined pursuant to Schedule 10.17 and Section
10.17(c) or (iii) all Eligible Properties have been transferred to an
Affiliated REIT.

Entity or by any of the stockholders of Koll seeking the issuance of such an
order or injunction, shall be pending which, in the good faith judgment of

                                INDEMNIFICATION
 
  13.1 Survival. The representations, warranties and covenants of Koll, the
Koll Shareholders, CBC and Acquisition Corporation contained in this Agreement
shall terminate at the Effective Time with the exceptions of (i) the
representations and warranties of the Koll Shareholders made in Section 4.1
(Title and Authority) which shall be of unlimited duration, (ii) the
representations and warranties of the Koll Shareholders made in Section 4.2
(Undisclosed Liabilities) which shall survive for one year following the
Effective Time and (iii) the representations and warranties of the Koll
Shareholders contained in Section 4.3 (Misstatements) which shall survive for
one year following the Effective Time and (iv) the representations and
warranties of CBC made in Sections 5.3(a) (Authority) and 5.9 (Issuance of
Common Stock) which shall be of unlimited duration. Each of the
representations and warranties listed in the foregoing clauses (i), (ii),
(iii) and (iv), any updates to the Schedules relating thereto and the
Certificates delivered pursuant to Sections 11.2(a) and 11.3(a) to the extent
they relate thereto shall be deemed renewed by the appropriate party at the
Closing as if made at such time and shall survive the Closing and continue in
full force and effect thereafter, for the respective periods set forth in
Clauses (i), (ii), (iii) and (iv), even if the damaged party knew or had
reason to know of any misrepresentation or breach of warranty at the time of
Closing, unless such misrepresentation or breach is disclosed in an Exhibit or
Schedule hereto or any updates to the Schedules pursuant to Section 10.8
hereof.
 
  13.2 Indemnification by the Koll Shareholders.
 
  (a) Except as otherwise expressly provided in this Section 13.2, on and
after the Closing Date, the Koll Shareholders shall defend, indemnify and hold
harmless CBC and Acquisition Corporation, and each of their respective
Affiliates, officers, directors, employees, agents, successors and assigns
(collectively, "CBC's Indemnified Persons"), and shall reimburse CBC's
Indemnified Persons, for, from and against, each and every demand, claim, loss
(which shall include any diminution in value), liability, judgment, and damage
(and costs and expenses, including attorneys' fees, (collectively, "Losses")
imposed on or incurred by CBC's Indemnified Persons, directly or indirectly,
relating to, resulting from or arising out of any inaccuracy in any
representation or warranty (which survived the Closing pursuant to Section
13.1) in any respect, whether or not CBC's Indemnified Persons relied thereon
or had knowledge thereof.
 
  (b) The Koll Shareholders shall have no liability under Section 13.2(a) in
the case of any inaccuracy contained in any representation or warranty
contained in Section 4.2 (Undisclosed Liabilities) or in Section 4.3
(Misstatements) unless and until the aggregate of all Losses relating thereto,
exceeds $2,000,000 (the "CBC Minimum Amount"), in which event the Koll
Shareholders shall be liable for all Losses, irrespective of the CBC Minimum
Amount.
 
  (c) Notwithstanding any other provision of this Agreement, the CBC Minimum
Amount shall not apply to any Losses relating to any inaccuracy in any
representation or warranty contained in Section 4.1 (Title and Authority)
hereof, regardless of whether any Losses relating thereto may also constitute
a Loss arising from the breach of a representation or warranty contained in
Section 4.2 (Undisclosed Liabilities) or in Section 4.3 (Misstatements),
provided, however, that each Koll Shareholder shall only be liable with
respect to such Koll Shareholder's own representations under Section 4.1
(Title and Authority) and shall have no liability with respect to any other
Koll Shareholder's representations under Section 4.1 (Title and Authority).
 
  (d) With respect to the breach of any representation or warranty contained
in Section 4.2 (Undisclosed Liabilities) only, (i) the maximum aggregate
amount for which the Koll Shareholders shall be liable pursuant to this
Article 13 shall be $17,500,000 and (ii) no Koll Shareholder shall be liable
for any Losses in excess of such Koll Shareholder's pro rata share of all
Losses relating to such inaccuracy, which pro rata share shall be determined
by dividing the aggregate value of shares of CBC Common issued plus the value
of all CBC Options issued to such Koll Shareholder pursuant to this Agreement
by the total value of all shares of CBC Common issued plus the value of all
CBC Options issued to the Koll Shareholders pursuant hereto.
 
                                     1-39
<PAGE>
 
  (e) A Koll Shareholder shall only have liability pursuant to Section 4.3
(Misstatements) if such Koll Shareholder knowingly furnished information which
breached Section 4.3 or had actual knowledge that Koll or a Koll Shareholder
furnished information which breached Section 4.3. In the case of a breach of
Section 4.3 (Misstatements), each Koll Shareholder with such knowledge shall
be jointly and severally liable for all losses relating thereto and, with
respect to a Koll Shareholder who is an individual, in addition to any other
liability hereunder, any CBC Options (other than those issued pursuant hereto)
held by such individual, whether vested or unvested, shall be terminated
immediately upon a finding by an arbitrator pursuant to Section 16.8 or by
another appropriate tribunal that such individual is liable pursuant hereto
and no such CBC Option may be exercised during any period during which a claim
made hereunder against such individual is being resolved.
 
  (f) The maximum amount for which a Koll Shareholder shall be liable for all
breaches of Sections 4.2 and 4.3 shall not exceed the value of the shares of
CBC Common and the CBC Options received by such Koll Shareholder pursuant
hereto. Such shares of CBC Common shall be valued at the average closing sales
price of a share of CBC Common as reported on the NASDAQ for the ten (10)
trading days ending on the trading day immediately prior to the Closing Date
and the value of a CBC Option shall be the difference between the exercise
price per share of CBC Common under such CBC Option and such average closing
price multiplied by the number of shares of CBC Common underlying such CBC
Option.
 
  (g) For purposes of determining pro rata share and the value received in the
Merger, the options of RW and WSR to purchase shares of Koll Common held by
KHC (described in Section 3.2(c)) shall be deemed to have been exercised
immediately prior to the Effective Time in a cashless exercise (such that
shares of Koll Common representing the exercise price shall be deemed to be
held by KHC and shares of Koll Common representing the value of such shares at
the Effective Time minus the exercise price shall be deemed to be held by RW
and WSR, as applicable). The value of each share of Koll Common for purposes
of this section shall be 0.79 multiplied by the average closing sales price of
a share of CBC Common as reported on the NASDAQ for the ten (10) trading days
ending on the trading day immediately prior to the Closing Date.
 
  (h) Any amounts payable by a Koll Shareholder to CBC pursuant to this
Article 13 may be paid in cash or in CBC Common received in the Merger or a
combination thereof. For purposes of this Section 13.2(g), such CBC Common
shall be valued at the average closing sales price of a share of CBC Common as
reported on the NASDAQ for the ten (10) trading days ending on the trading day
immediately prior to the date on which the claim for a Loss is finalized and
liquidated.
 
  13.3 Indemnification by CBC. Except as otherwise expressly provided in this
Section 13.3, on or after the Closing Date, CBC shall defend, indemnify and
hold harmless the Koll Shareholders and each of their respective Affiliates,
officers, directors, employees, agents, successors, heirs and assigns (the
Koll Shareholders and such other persons, collectively "Shareholders'
Indemnified Persons") and shall reimburse the Shareholders' Indemnified
Persons for, from and against all Losses imposed on or incurred by the
Shareholders' Indemnified Persons, directly or indirectly, relating to,
resulting from or arising out of any inaccuracy in any representation or
warranty contained in Sections 5.3(a) and 5.9 hereof in any respect, whether
or not Shareholders' Indemnified Persons relied thereon or had knowledge
thereof.
 
  13.4 Notice and Defense of Third-Party Claims. If any Proceeding shall be
brought or asserted under this Section 13.4 against an indemnified party or
any successor thereto (the "Indemnified Person") in respect of which indemnity
may be sought under this Article 13 from an indemnifying person or any
successor thereto (the "Indemnifying Person"), the Indemnified Person shall
give prompt written notice of such Proceeding to the Indemnifying Person who
shall assume the defense thereof, including the employment of counsel
reasonably satisfactory to the Indemnified Person and the payment of all
expenses; except that any delay or failure to so notify the Indemnifying
Person shall relieve the Indemnifying Person of its obligations hereunder only
to the extent, if at all, that it is prejudiced by reason of such delay or
failure. The Indemnified Person shall have the right to employ separate
counsel in any of the foregoing Proceedings and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Person unless both the
 
                                     1-40
<PAGE>
 
Indemnified Person and the Indemnifying Person are named as parties and the
Indemnified Person shall in good faith determine that the representation by
the same counsel is inappropriate. In the event that the Indemnifying Person,
within ten days after notice of any such Proceeding, fails to assume the
defense thereof, the Indemnified Person shall have the right to undertake the
defense, compromise or settlement of such Proceeding for the account of the
Indemnifying Persons, subject to the right of the Indemnifying Person to
assume, at its expense, the defense of such Proceeding with counsel
satisfactory to the Indemnified Person at any time prior to the settlement,
compromise or final determination thereof. Anything in this Article 13 to the
contrary notwithstanding, the Indemnifying Person shall not, without the
Indemnified Person's prior written consent, settle or compromise any
Proceeding or consent to the entry of any judgment with respect to any
Proceeding for anything other than money damages paid by the Indemnifying
Person. The Indemnifying Person may, without the Indemnified Person's prior
written consent, settle or compromise any such Proceeding or consent to entry
of any judgment with respect to any such Proceeding that requires solely the
payment of money damages by the Indemnifying Person and that includes as an
unconditional term thereof the release by the claimant or the plaintiff of the
Indemnified Person from all liability with respect to such Proceeding.
 
  13.5 Exclusivity. From and after the Closing Date, the rights and remedies
provided in this Article 13 shall be the exclusive rights and remedies,
contractual or otherwise, of the Indemnified Persons with respect to
inaccuracies in the representations and warranties contained in this
Agreement.
 
                                  ARTICLE 14
 
                              PAYMENT OF EXPENSES
 
  CBC shall pay the reasonable fees and expenses incurred incident to the
preparation and carrying out of the transactions herein contemplated
(including legal, accounting and investment banking services and travel)
provided however that the aggregate amount payable by CBC and Koll for all
fees and expenses of all legal counsel to Koll and the Koll Shareholders shall
not exceed $500,000 and any amount payable in excess of such amount for fees
and expenses of legal counsel of Koll and the Koll Shareholders shall be
payable by the Koll Shareholders. CBC shall also pay all government filing
fees including under the HSR Act and with the SEC, any state securities
commission, and the Department of Corporations and the costs of printing,
filing and mailing the Form S-4 and Proxy Statement (collectively, the "Filing
Fees"). Notwithstanding the foregoing, Koll shall bear all the Filing Fees and
all reasonable fees and expenses (including without limitation, fees and
expenses payable to counsel to CBC, outside consultants, accountants and to
all investment banking firms and their respective counsel) actually incurred
by CBC and Acquisition Corporation in the event that Koll's stockholders fail
to approve the Merger by that date which is twenty (20) days after the
effective date of the Registration Statement on Form S-4 to be filed in
connection with the Merger or shareholders of Koll holding over 350,000 shares
exercise dissenter's rights. Also notwithstanding the foregoing, if the
transactions contemplated hereby are not consummated by October 31, 1997, each
party hereto shall be responsible for its own fees and expenses and Koll and
the Koll Shareholders shall promptly reimburse CBC for any amounts advanced,
reimbursed or otherwise paid to them by CBC pursuant to this provision. Each
party shall promptly advance upon request or reimburse such party's portion of
these fees.

arbitration conducted expeditiously by a single arbitrator in accordance with
the Rules for Non-Administered Arbitration of Business Disputes promulgated by
the CPR Institute for Dispute Resolution (formerly Center for Public

submitted in connection with such proceedings shall not be admissible in any
other proceeding; provided, however, that this confidentiality provision shall
not prevent a petition to vacate or enforce an arbitral award, and shall not

provision shall have no preclusive effect in any other matter involving third
parties.

                               WARRANT AGREEMENT
 
  THIS WARRANT AGREEMENT (the "Agreement") is made and entered into as of
            , 1997 between CB Commercial Real Estate Services Group, Inc., a
Delaware corporation (the "Company"), FS Equity Partners III, L.P., FS Equity
Partners International L.P., AP KMS Partners, L.P., AP KMS II, LLC, Koll
Holding Company and the individuals listed on the signature pages hereto.
 
  WHEREAS, pursuant to that certain Agreement and Plan of Reorganization (the
"Merger Agreement"), dated as of May 13, 1997 by and between the Company, Koll
Real Estate Services ("KRES") and the other parties listed therein, KRES will
be merged with a subsidiary of the Company and the holders of shares of common
stock of KRES and options exercisable into shares of common stock of KRES
shall receive warrants (the "Warrants") to purchase up to an aggregate of
500,000 shares (the "Warrant Shares") of the Common Stock of the Company (the
"Common Stock").
 
  NOW THEREFORE, in consideration of the premises and the mutual agreements
herein set forth, the parties hereto agree as follows (capitalized terms used
herein and not otherwise defined have the meanings ascribed thereto in the
Merger Agreement):
 
  SECTION 1. Exercise of Warrant. Subject to the terms of this Agreement, each
holder of a Warrant may, at any time on and after              , 2000, but not
later than            , 2004, exercise this Warrant in whole at any time or in
part from time to time for the number of Warrant Shares which such holder is
then entitled to purchase hereunder.
 
  Each holder of a Warrant may exercise such Warrant, in whole or in part by
either of the following methods:
 
  (a) delivering to the Company at its office maintained for such purpose
pursuant to Section 12(d) (i) a written notice of such holder's election to
exercise this Warrant, which notice shall specify the number of Warrant Shares
to be purchased, (ii) this Warrant and (iii) a sum equal to the Exercise Price
(as set forth in the Warrant Certificate attached hereto) therefor payable in
immediately available funds; or
 
  (b) The holder of this Warrant may also exercise this Warrant, in whole or
in part, in a "cashless" or "net-issue" exercise by delivering to the Issuer
at its office maintained for such purpose pursuant to Section 12(d) (i) a
written notice of such holder's election to exercise this Warrant, which
notice shall specify the number of Warrant Shares to be delivered to such
holder and the number of Warrant Shares with respect to which this Warrant is
being surrendered in payment of the aggregate Exercise Price for the Warrant
Shares to be delivered to the holder, and (ii) the Warrant. For purposes of
this provision, all Warrant Shares as to which the Warrant is surrendered will
be attributed a value equal to the product of (x) the current market price per
share of Common Stock (determined in the manner set forth in Section 7(f))
minus the current Exercise Price per share of Common Stock.
 
  Such notice may be in the form of Election to Purchase set out at the end of
this Warrant Agreement. Upon delivery thereof, the Company shall cause to be
executed and delivered to such holder within five business days a certificate
or certificates representing the aggregate number of fully-paid and
nonassessable shares of Common Stock issuable upon such exercise.
 
  The stock certificate or certificates for Warrant Shares so delivered shall
be in such denominations as may be specified in said notice and shall be
registered in the name of such holder or such other name or names as shall be
designated in said notice. Such certificate or certificates shall be deemed to
have been issued and such holder or any other person so designated to be named
therein shall be deemed to have become a holder of record of such shares,
including to the extent permitted by law the right to vote such shares or to
consent or to receive notice as a stockholder, as of the time said notice is
delivered to the Issuer as aforesaid. If a Warrant shall have been exercised
only in part, the Company shall, at the time of delivery of said certificate
or certificates, deliver
 
                                      2-1
<PAGE>
 
to such holder a new Warrant dated the date it is issued, evidencing the
rights of such holder to purchase the remaining Warrant Shares called for by
this Warrant, which new Warrant shall in all other respects be identical with
this Warrant, or, at the request of such holder, appropriate notation may be
made on this Warrant and the Warrant shall be returned to such holder.
 
  All Warrant Shares issuable upon the exercise of a Warrant shall be validly
issued, fully paid and nonassessable and free from all liens and other
encumbrances thereon, other than liens or other encumbrances created by the
holder thereof.
 
  The Company will not close its books against the transfer of a Warrant or of
any Warrant Shares in any manner which interferes with the timely exercise of
a Warrant. The Issuer will from time to time take all such action as may be
necessary to assure that the par value per share of the unissued Common Stock
acquirable upon exercise of a Warrant is at all times equal to or less than
the Exercise Price then in effect.
 
  SECTION 2. Transfer, Division and Combination. The Warrants are, and all
rights thereunder are, transferable, in whole or in part, on the books of the
Company to be maintained for such purpose, upon surrender of a Warrant at the
office of the Company maintained for such purpose pursuant to Section 12(d),
together with a written assignment of such Warrant duly executed by the holder
thereof or its agent or attorney and payment of funds sufficient to pay any
stock transfer taxes payable upon the making of such transfer. Upon such
surrender and, if required, such payment, the Company shall, execute and
deliver a new Warrant or Warrants in the name of the assignee or assignees and
in the denominations specified in such instrument of assignment, and the
surrendered Warrant shall promptly be canceled. If and when a Warrant is
assigned in blank, the Company may (but shall not be obligated to) treat the
bearer thereof as the absolute owner of such Warrant for all purposes and the
Company shall not be affected by any notice to the contrary. A Warrant, if
properly assigned in compliance with this Section 2, may be exercised by an
assignee for the purchase of shares of Common Stock without having a new
Warrant issued.
 
  A Warrant may, be divided or combined with other Warrants upon presentation
at the aforesaid office of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by the holder hereof or its agent or attorney. Subject to compliance
with the preceding paragraph, as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant
or Warrants in exchange for the Warrant or Warrants to be divided or combined
in accordance with such notice.
 
  The Company agrees to maintain at its aforesaid office books for the
registration and transfer of the Warrants.
 
  SECTION 3. Payment of Taxes. The Company will pay all documentary stamp
taxes attributable to the initial issuance of Warrant Shares upon the exercise
of Warrants; provided, however, that the Company shall not be required to pay
any tax or taxes which may be payable in respect of any transfer involved in
the issue of any Warrant Certificates or any certificates for Warrant Shares
in a name other than that of the registered holder of a Warrant Certificate
surrendered upon the exercise of a Warrant, and the Company shall not be
required to issue or deliver such Warrant Certificates unless or until the
person or persons requesting the issuance thereof shall have paid to the
Company the amount of such tax or shall have established to the satisfaction
of the Company that such tax has been paid.
 
  SECTION 4. Mutilated or Missing Warrants Certificates. In case any of the
Warrant Certificates shall be mutilated, lost, stolen or destroyed, the
Company may in its discretion issue, in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor and representing an equivalent number of
Warrants, but only upon receipt of evidence satisfactory to the Company of
such loss, theft or destruction of such Warrant Certificate and indemnity, if
requested, also satisfactory to them. Applicants for such
 
                                      2-2
<PAGE>
 
substitute Warrant Certificates shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may
prescribe.
 
  SECTION 5. Reservation of Warrant Shares. The Company will at all times
reserve and keep available, free from preemptive rights, out of the aggregate
of its authorized but unissued Common Stock or its authorized and issued
Common Stock held in its treasury, for the purpose of enabling it to satisfy
any obligation to issue Warrant Shares upon exercise of Warrants, the maximum
number of shares of Common Stock which may then be deliverable upon the
exercise of all outstanding Warrants.
 
  The Company or, if appointed, the transfer agent for the Common Stock (the
"Transfer Agent") and every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of any of the rights of
purchase aforesaid will be irrevocably authorized and directed at all times to
reserve such number of authorized shares as shall be required for such
purpose. The Company will keep a copy of this Agreement on file with the
Transfer Agent and with every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of the rights of purchase
represented by the Warrants. The Company will furnish such Transfer Agent a
copy of all notices of adjustments and certificates related thereto
transmitted to each holder pursuant to Section 10 hereof.
 
  SECTION 6. Obtaining Stock Exchange Listings. The Company will from time to
time take all action which may be necessary so that the Warrant Shares,
immediately upon their issuance upon the exercise of Warrants, will be listed
on the principal securities exchanges and markets within the United States of
America (including the NASDAQ National Market), if any, on which other shares
of Common Stock are then listed.
 
  SECTION 7. Adjustment of Exercise Price. The Exercise Price and the number
of Warrant Shares issuable upon the exercise of each Warrant are subject to
adjustment from time to time upon the occurrence of the events enumerated in
this Section 7. For purposes of this Section 7, "Common Stock" means shares
now or hereafter authorized of any class of common stock of the Company and
any other stock of the Company, however designated, that has the right
(subject to any prior rights of any class or series of preferred stock) to
participate in any distribution of the assets or earnings of the Company
without limit as to per share amount.
 
  (a) Adjustment for Change in Capital Stock.
 
  If the Company:
 
    (1) pays a dividend or makes a distribution on its Common Stock in shares
  of its Common Stock;
 
    (2) subdivides its outstanding shares of Common Stock into a greater
  number of shares;
 
    (3) combines its outstanding shares of Common Stock into a smaller number
  of shares;
 
 
    (4) makes a distribution on its Common Stock in shares of its capital
  stock other than Common Stock; or
 
    (5) issues by reclassification of its Common Stock any shares of its
  capital stock;
 
then the Exercise Price in effect immediately prior to such action and the
number and kind of shares into which a Warrant is exercisable shall all be
adjusted appropriately so that the holder of any Warrant thereafter exercised
may receive the aggregate number and kind of shares of capital stock of the
Company which he would have owned immediately following such action if such
Warrant had been exercised immediately prior to such action.
 
  The adjustment shall become effective immediately after the record date in
the case of a dividend or distribution and immediately after the effective
date in the case of a subdivision, combination or reclassification.
 
  If after an adjustment a holder of a Warrant upon exercise of it may receive
shares of two or more classes of capital stock of the Company, the Board of
Directors of the Company shall determine the allocation of the
 
                                      2-3
<PAGE>
 
adjusted Exercise Price between the classes of capital stock. After such
allocation, the exercise privilege and the Exercise Price of each class of
capital stock shall thereafter be subject to adjustment on terms comparable to
those applicable to Common Stock in this Section.
 
  Such adjustment shall be made successively whenever any event listed above
shall occur.
 
  (b) Adjustment for Rights Issue.
 
  If the Company distributes any rights, options or warrants to all holders of
its Common Stock entitling them for a period expiring within 60 days after the
record date for such distribution to purchase shares of Common Stock at a
price per share less than the current market price per share on that record
date, the Exercise Price shall be adjusted in accordance with the formula:
 

                                        O + N x P
                                           -----
                                 E' = E x    M
                                           -----
                                           O + N
 
where:
 
  E' = the adjusted Exercise Price.
 
  E = the current Exercise Price.
 
  O = the number of shares of Common Stock outstanding on the record date.
 
  N = the number of additional shares of Common Stock offered pursuant to
  such rights issue.
 
  P = the offering price per share of the additional shares.
 
  M = the current market price per share of Common Stock on the record date.
 
  The adjustment shall be made successively whenever any such rights, options
or warrants are issued and shall become effective immediately after the record
date for the determination of stockholders entitled to receive the rights,
options or warrants. If at the end of the period during which such rights,
options or warrants are exercisable, not all rights, options or warrants shall
have been exercised, the Exercise Price shall be immediately readjusted to
what it would have been if "N" in the above formula had been the number of
shares actually issued.
 
  (c) Adjustment for Other Distributions.
 
  If the Company distributes to all holders of its Common Stock any assets
(excluding cash) or debt securities or any rights or warrants to purchase debt
securities, assets or other securities, the Exercise Price shall be adjusted
in accordance with the formula:
 
                                   E' = E x M - F
                                            -----
                                              M
 
where:
 
  E' = the adjusted Exercise Price.
 
  E = the current Exercise Price.
 
  M = the current market price per share of Common Stock on the record date
  mentioned below.
 
  F = the aggregate fair market value on the record date of the assets,
     securities, rights or warrants divided by the number of outstanding
     shares of Common Stock on the record date for such distribution. The
     Board of Directors of the Company shall determine the fair market value.
 
 
                                      2-4
<PAGE>
 
  The adjustment shall be made successively whenever any such distribution is
made and shall become effective immediately after the record date for the
determination of stockholders entitled to receive the distribution.
 
  (d) Adjustment for Common Stock Issue:
 
  If the Company issues shares of Common Stock for a consideration per share
less than the current market price per share on the date the Company fixes the
offering price of such additional shares, the Exercise Price shall be adjusted
in accordance with the formula:
 
                                                P
                                                - 
                                   E' = E x O + M
                                            -----
                                              A
 
where:
 
  E' = the adjusted Exercise Price.
 
  E = the then current Exercise Price.
 
  O = the number of shares outstanding immediately prior to the issuance of
  such additional shares.
 
  P = the aggregate consideration received for the issuance of such
  additional shares.
 
  M = the current market price per share on the date of issuance of such
  additional shares.
 
  A = the number of shares outstanding immediately after the issuance of such
  additional shares.
 
  The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance.
 
  This subsection (d) does not apply to:
 
    (1) any of the transactions described in subsections (b) and (c) of this
  Section 7,
 
    (2) the exercise of Warrants, or the conversion or exchange of other
  securities convertible into, or exchangeable or exercisable for, Common
  Stock,
 
    (3) Common Stock issued to the Company's employees under bona fide
  employee benefit plans adopted by the Board of Directors and approved by
  the holders of Common Stock when required by law, if such Common Stock
  would otherwise be covered by this subsection (d),
 
    (4) Common Stock issued upon the exercise of rights or warrants issued to
  the holders of Common Stock,
 
    (5) Common Stock issued to shareholders of any person which merges into
  the Company in proportion to their stock holdings of such person
  immediately prior to such merger, upon such merger,
 
    (6) Common Stock issued in a bona fide public offering pursuant to a firm
  commitment underwriting,
 
    (7) Common Stock issued in a bona fide private placement to, or through a
  placement agent which is, a member firm of the National Association of
  Securities Dealers, Inc., or
 
    (8) Common Stock issued as a dividend on any preferred stock in
  accordance with the stated terms of such preferred stock and in lieu of
  cash dividends otherwise payable on such preferred stock pursuant to the
  instrument under which the preferred stock was issued.
 
  (e) Adjustment for Convertible Securities Issue.
 
  If the Company issues any securities convertible into or exchangeable or
exercisable for Common Stock (other than securities issued in transactions
described in subsections (b) and (c) of this Section 7) for a
 
                                      2-5
<PAGE>
 
consideration per share of Common Stock initially deliverable upon conversion
or exchange of such securities less than the current market price per share on
the date of issuance of such securities, the Exercise Price shall be adjusted
in accordance with this formula:
 
                                                P
                                                -
                                   E' = E x O + M
                                            -----
                                            O + D
 
where:
 
  E' = the adjusted Exercise Price.
 
  E = the then current Exercise Price.
 
  O = the number of shares outstanding immediately prior to the issuance of
  such securities.
 
  P = the aggregate consideration received for the issuance of such
  securities.
 
  M = the current market price per share of Common Stock on the date of
  issuance of such securities.
 
  D = the maximum number of shares deliverable upon conversion or in exchange
     for such securities at the initial conversion or exchange rate.
 
  The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance.
 
  If all of the Common Stock deliverable upon conversion or exchange of such
securities has not been issued when such securities are no longer outstanding,
then the Exercise Price shall promptly be readjusted to the Exercise Price
which would then be in effect had the adjustment upon the issuance of such
securities been made on the basis of the actual number of shares of Common
Stock issued upon conversion or exchange of such securities.
 
  This subsection (e) does not apply to:
 
    (1) convertible securities issued to shareholders of any person which
  merges into the Company, or with a subsidiary of the Company, in proportion
  to their stock holdings of such person immediately prior to such merger,
  upon such merger,
 
    (2) convertible securities issued in a bona fide public offering pursuant
  to a firm commitment underwriting,
 
    (3) convertible securities issued in a bona fide private placement
  through a placement agent which is a member firm of the National
  Association of Securities Dealers, Inc.,
 
    (4) rights, warrants and convertible and exchangeable securities
  outstanding on or prior to the date of issuance of the Warrant, or
 
    (5) convertible securities or warrants issued in connection with the
  incurrence of debt by the Company, so long as the fair value allocable to
  such convertible securities or warrants (taking into account the terms of
  the debt), together with any consideration payable to the Company upon
  conversion or exercise of such convertible securities or warrants, treating
  such convertible securities or warrants on an as converted basis, is no
  less than the then current market price of Common Stock on the date of
  issuance of such convertible securities or warrants.
 
  (f) Current Market Price.
 
  In subsections (b), (c), (d) and (e) of this Section 7 the current market
price per share of Common Stock on any date is the average of the Quoted
Prices of the Common Stock for 30 consecutive trading days commencing 45
trading days before the date in question. The "Quoted Price" of the Common
Stock is the last reported sales
 
                                      2-6
<PAGE>
 
price of the Common Stock as reported by NASDAQ National Market, or if the
Common Stock is listed on a securities exchange, the last reported sales price
of the Common Stock on such exchange which shall be for consolidated trading
if applicable to such exchange, or if neither so reported or listed, the last
reported bid price of the Common Stock. In the absence of one or more such
quotations, the Board of Directors of the Company shall determine the current
market price on the basis of such quotations or other valuation information as
it in good faith considers appropriate.
 
  (g) Consideration Received.
 
  For purposes of any computation respecting consideration received pursuant
to subsections (d) and (e) of this Section 7, the following shall apply:
 
    (1) in the case of the issuance of shares of Common Stock for cash, the
  consideration shall be the amount of such cash, provided that in no case
  shall any deduction be made for any commissions, discounts or other
  expenses incurred by the Company for any underwriting of the issue or
  otherwise in connection therewith;
 
    (2) in the case of the issuance of shares of Common Stock for a
  consideration in whole or in part other than cash, the consideration other
  than cash shall be deemed to be the fair market value thereof as determined
  in good faith by the Board of Directors (irrespective of the accounting
  treatment thereof), whose determination shall be conclusive; and
 
    (3) in the case of the issuance of securities convertible into or
  exchangeable for shares, the aggregate consideration received therefor
  shall be deemed to be the consideration received by the Company for the
  issuance of such securities plus the additional minimum consideration, if
  any, to be received by the Company upon the conversion or exchange thereof
  (the consideration in each case to be determined in the same manner as
  provided in clauses (1) and (2) of this subsection).
 
  (h) When De Minimis Adjustment May Be Deferred.
 
  No adjustment in the Exercise Price need be made unless the adjustment would
require on increase or decrease of at least 1% in the Exercise Price. Any
adjustments that are not made shall be carried forward and taken into account
in any subsequent adjustment.
 
  All calculations under this Section shall be made to the nearest cent or
nearest 1/100th of a share as the case may be.
 
  (i) When No Adjustment Required.
 
  No adjustment need be made for a transaction referred to in subsection (a),
(b), (c), (d) or (e) of this Section 7 if Warrant holders are permitted to
participate in the transaction (without being required to exercise their
Warrants in order to do so) on a basis and with notice that the Board of
Directors of the Company determines to be fair and appropriate in light of the
basis and notice on which holders of Common Stock participate in the
transaction.
 
  No adjustment need be made for rights to purchase Common Stock pursuant to a
Company plan for reinvestment of dividends or interest.
 
  No adjustment need be made for a change in the par value or no par value of
the Common Stock.
 
  To the extent the Warrants become convertible into cash, no adjustment need
be made thereafter as to the cash. Interest will not accrue on the cash.
 
                                      2-7
<PAGE>
 
  (j) Notice of Adjustment.
 
  Whenever the Exercise Price is adjusted, the Company shall provide the
notices required by Section 10 hereof.
 
  (k) Voluntary Reduction.
 
  The Company from time to time may reduce the Exercise Price by any amount
for any period of time if the period is at least 20 days and if the reduction
is irrevocable during the period; provided, however, that in no event may the
Exercise Price be less than the par value of a share of Common Stock.
 
  Whenever the Exercise Price is reduced, the Company shall mail to Warrant
holders a notice of the reduction. The Company shall mail the notice at least
15 days before the date the reduced Exercise Price takes effect. The notice
shall state the reduced Exercise Price and the period it will be in effect.
 
  A reduction of the Exercise Price pursuant to this clause (k) does not
change or adjust the Exercise Price otherwise in effect for purposes of
subsections (a), (b), (c), (d) and (e) of this Section 7.
 
  (l) Reorganization of Company.
 
  If the Company consolidates or merges with or into, or sells, transfers or
leases all or substantially all of its assets to, any person, upon
consummation of such transaction the Warrants shall automatically become
exercisable for the kind and amount of securities, cash or other assets which
the holder of a Warrant would have owned immediately after the consolidation,
merger, sale, transfer or lease if the holder had exercised the Warrant
immediately before the effective date of the transaction. Concurrently with
the consummation of such transaction, the corporation formed by or surviving
any such consolidation or merger, if other than the Company, or the person to
which such transfer, sale or lease shall have been made, shall enter into a
supplemental Warrant Agreement so providing and further providing for
adjustments which shall be as nearly equivalent as may be practical to the
adjustments provided for in this Section. The successor Company shall mail to
warrant holders a notice describing the supplemental Warrant Agreement.
 
  If the issuer of securities deliverable upon exercise of Warrants under the
supplemental Warrant Agreement is an affiliate of the formed, surviving,
transferee or lessee corporation, that issuer shall join in the supplemental
Warrant Agreement.
 
  If this subsection (l) applies, subsections (a), (b), (c), (d) and (e) of
this Section 7 do not apply.
 
  (m) Determinations Conclusive.
 
  Any determination that the Company or the Board of Directors of the Company
must make pursuant to subsection (a), (c), (d), (e), (f), (g) or (i) of this
Section 7 is conclusive, provided the Board of Directors has acted reasonably.
 
  (n) When Issuance or Payment May Be Deferred.
 
  In any case in which this Section 7 shall require that an adjustment in the
Exercise Price be made effective as of a record date for a specified event,
the Company may elect to defer until the occurrence of such event (i) issuing
to the holder of any Warrant exercised after such record date the Warrant
Shares and such securities or assets, if any, issuable upon such exercise over
and above the Warrant Shares and such securities or assets, if any, issuable
upon such exercise on the basis of the Exercise Price and (ii) paying to such
holder any amount in cash in lieu of a fractional share pursuant to Section 9;
provided, however, that the Company shall deliver to such holder a due bill or
other appropriate instrument evidencing such holder's right to receive such
additional warrant Shares, other capital stock and cash upon the occurrence of
the event requiring such adjustment.
 
                                      2-8
<PAGE>
 
  (o) Adjustment in Number of Shares.
 
  Upon each adjustment of the Exercise Price pursuant to this Section 7, each
Warrant outstanding prior to the making of the adjustment in the Exercise
Price shall thereafter evidence the right to receive upon payment of the
adjusted Exercise Price that number of shares of Common Stock (calculated to
the nearest hundredth) obtained from the following formula:
 
                                 N' = N x  E
                                          ---
                                           E'
 
where:
 
  N' = the adjusted number of Warrant Shares issuable upon exercise of a
       Warrant by payment of the adjusted Exercise Price.
 
  N  = the number of Warrant Shares previously issuable upon exercise of a
       Warrant by payment of the Exercise Price prior to adjustment.
 
  E' = the adjusted Exercise Price.
 
  E  = the Exercise Price prior to adjustment.
 
  SECTION 8. Forfeiture of Warrants. The Warrants issued in respect of options
to purchase KRES common stock are subject to forfeiture as set forth in
Section 10.12(c) of the Merger Agreement, if the option(s) to purchase KRES
common stock in respect of which such Warrant is issued expire or terminate
without being exercised. Upon the termination of any such option all such
Warrants issued in respect thereof shall be forfeit and the holder thereof
shall immediately surrender the Warrant Certificate representing such Warrants
to the Company. If the Warrant Certificate so surrendered to the Company
represents other Warrants in addition to those forfeited, the Company shall
promptly issue a new Warrant Certificate to the holder thereof representing
the number of Warrants represented by such Warrant Certificate and not
forfeited.
 
  SECTION 9. Fractional Interests. The Company shall not be required to issue
fractional Warrant Shares on the exercise of Warrants. If more than one
Warrant shall be presented for exercise in full at the same time by the same
holder, the number of full Warrant Shares which shall be issuable upon the
exercise thereof shall be computed on the basis of the aggregate number of
Warrant Shares purchasable on exercise of the Warrants so presented. If any
fraction of a Warrant Share would, except for the provisions of this Section 9
be issuable on the exercise of any Warrants (or specified portion thereof),
the Company shall pay an amount in cash equal to the current Exercise Price,
multiplied by such fraction.
 
  SECTION 10. Notices to Warrant Holders. Upon any adjustment of the Exercise
Price pursuant to Section 7, the Company shall promptly thereafter cause to be
given to each of the registered holders of the Warrant Certificates at its
address appearing on the Warrant register written notice of such adjustment by
first-class mail, postage prepaid. Where appropriate, such notice may be given
in advance and included as a part of the notice required to be mailed under
the other provisions of this Section 7.
 
  In case:
 
  (a) the Company shall authorize the issuance to all holders of shares of
Common Stock of rights, options or warrants to subscribe for or purchase
shares of Common Stock or of any other subscription rights or warrants; or
 
  (b) the Company shall authorize the distribution to all holders of shares of
Common Stock of evidences of indebtedness or assets, including cash dividends
or cash distributions payable out of consolidated current or retained
earnings, but not including dividends payable in shares of Common Stock or
distributions referred to in subsection (a) of Section 7 hereof; or
 
 
                                      2-9
<PAGE>
 
  (c) of any consolidation or merger to which the Company is a party and of
which approval of any shareholders of the Company is required, or of the
conveyance, sale, transfer or lease of the properties and assets of the
Company substantially as an entirety, or of any reclassification or change of
Common Stock issuable upon exercise of the Warrants (other than a change in
par value, or from par value to no par value, or from no par value to par
value, or as a result of a subdivision or combination), or a tender offer or
exchange offer for shares of Common Stock; or
 
  (d) of the voluntary or involuntary dissolution, liquidation or winding up
of the Company; or
 
  (e) the Company proposes to take any action (other than actions of the
character described in Section 7(a)) that would require an adjustment of the
Exercise Price pursuant to Section 7;
 
then the Company shall cause to be given to each of the registered holders of
the Warrant Certificates at his address appearing on the Warrant register, at
least 20 days (or 10 days in any case specified in clause (a) or (b) above)
prior to the applicable record date hereinafter specified, or promptly in the
case of events for which there is no record date, by first-class mail, postage
prepaid, a written notice stating (i) the date as of which the holders of
record of shares of Common Stock to be entitled to receive any such rights,
options, warrants or distribution are to be determined, or (ii) the initial
expiration date set forth in any tender offer or exchange offer for shares of
Common Stock, or (iii) the date on which any such consolidation, merger,

                         [FORM OF WARRANT CERTIFICATE]
 
                                   [REVERSE]
 
  The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants expiring                , 2004 entitling the
holder on exercise to receive shares of Common Stock, of the Company (the
"Common Stock"), $.01 par value, and are issued or to be issued pursuant to a
Warrant Agreement dated as of                (the "Warrant Agreement"), duly
executed and delivered by the Company, which Warrant Agreement is hereby
incorporated by reference in and made a part of this instrument and is hereby
referred to for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Company and the holders
(the words "holders" or "holder" meaning the registered holders or registered
holder) of the Warrants. A copy of the Warrant Agreement may be obtained by
the holder hereof upon written request to the Company.
 
  Warrants may be exercised at any time on or after             , 2000 and on
or before               , 2004. The holder of Warrants evidenced by this
Warrant Certificate may exercise them, subject to the limitations set forth in
the Warrant Agreement, by surrendering this Warrant Certificate, with the form
of election to purchase set forth hereon properly completed and executed,
together with payment of the Exercise Price in cash or immediately available
funds or in Warrant Shares by "cashless exercise," at the principal office of
the Company. In the event that upon any exercise of Warrants evidenced hereby
the number of Warrants exercised shall be less than the total number of
Warrants evidenced hereby, there shall be issued to the holder hereof or his
assignee a new Warrant Certificate evidencing the number of Warrants not
exercised. No adjustment shall be made for any dividends on any Common Stock
issuable upon exercise of this Warrant.
 
  The Warrant Agreement provides that upon the occurrence of certain events
the Exercise Price and the number of Warrant Shares into which this Warrant is
exercisable set forth on the face hereof may, subject to certain conditions,
be adjusted. No fractions of a share of Common stock will be issued upon the
exercise of any Warrant, but the Company will pay the cash value thereof
determined as provided in the Warrant Agreement.
 
  Warrant Certificates, where surrendered at the principal office of the
Company by the registered holder thereof in person or by legal representative
or attorney duly authorized in writing, may be exchanged, in the manner and
subject to the limitations provided in the Warrant Agreement, but without
payment of any service charge, for another Warrant Certificate or Warrant
Certificates of like tenor evidencing in the aggregate a like number of
Warrants.
 
  Upon due presentation for registration of transfer of this Warrant
Certificate at the principal office of the Company a new Warrant Certificate
or Warrant Certificates of like tenor and evidencing in the aggregate a like
number of Warrants shall be issued to the transferee(s) in exchange for this
Warrant Certificate, subject to the limitations provided in the Warrant
Agreement, without charge except for any tax or other governmental charge
imposed in connection therewith.
 
  The Company and the Warrant Agent may deem and treat the registered
holder(s) hereof as the absolute owner(s) of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by
anyone), for the purpose of any exercise hereof, of any distribution to the
holder(s) hereof, and for all other purposes, and the Company shall not be
affected by any notice to the contrary. Neither the Warrants nor this Warrant
Certificate entitle any holder hereof to any rights of a stockholder of the
Company.

Attention: Walter V. Stafford
 
Gentlemen:
 
  CB Commercial Real Estate Services Group, Inc. (the "Company"), CBC
Acquisition Corporation, a wholly owned subsidiary of the Company (the
"Acquisition Sub"), Koll Real Estate Services (the "Subject Company") and
certain related parties propose to enter into an agreement (the "Agreement")
pursuant to which the Acquisition Sub will be merged with and into the Subject
Company in a transaction (the "Merger") in which each outstanding share of the
Subject Company's common stock, par value $.01 per share (the "Shares"), will
be converted into the right to receive (i) 0.79 shares of the common stock of
the Company (the "Company Shares") and (ii) a warrant (the "Warrants")
exercisable into 0.0691 Company Shares at an exercise price of $30.00 per
Company Share during the four-year period commencing three (3) years after the
issue date thereof and ending seven (7) years after such issue date (the
"Transaction Consideration").
 
  You have asked us whether, in our opinion, the Transaction Consideration is
fair from a financial point of view to the Company.
 
  In arriving at the opinion set forth below, we have, among other things:
 
   (1) Reviewed the Subject Company's Audited Consolidated Financial
       Statements and related financial information for the fiscal year ended
       March 31, 1996, periods from December 1, 1994 through March 31, 1995
       and April 1, 1994 through November 30, 1994, and the year ended March
       31, 1994; the Subject Company's related unaudited financial
       information for the three years ended December 31, 1996; and the
       Subject Company's Registration Statement on Form S-1 filed with the
       Securities and Exchange Commission;
 
   (2) Reviewed the Company's Annual Reports on Form 10-K and related
       financial information for the three fiscal years ended December 31,
       1996; the Company's quarterly reports on Form 10-Q and the related
       unaudited financial information for the quarterly periods ending March
       31, 1996, June 30, 1996 and September 30 , 1996; and certain other of
       the Company's filings with the Securities and Exchange Commission
       during the last three years, including certain reports on Form 8-K and
       its Registration Statement on Form S-1;
 
   (3) Reviewed certain information, including financial forecasts, relating
       to the business, earnings, cash flow, assets, liabilities and
       prospects of the Subject Company and the Company, as well as the
       synergies and the amount and timing of the related cost savings and
       expenses expected to result from the Merger (the "Expected Synergies")
       furnished to us by the Subject Company and the Company, respectively;
 
   (4) Conducted discussions with members of senior management and
       representatives of the Subject Company and the Company concerning
       their respective businesses and prospects, before and after giving
       effect to the Merger, and the Expected Synergies;
 
                                      3-1
<PAGE>
 
   (5) Reviewed the market prices and valuation multiples for the Company
       Shares and compared them with those of certain publicly traded
       companies that we deemed relevant;
 
   (6) Reviewed the results of operations of the Subject Company and the
       Company and compared them with those of certain companies that we
       deemed relevant;
 
   (7) Reviewed, under applicable valuation methodologies, the theoretical
       valuation of the Warrants to be issued under the terms of the
       Agreement;
 
   (8) Compared the proposed financial terms of the Merger with the financial
       terms of certain other transactions that we deemed relevant;
 
   (9) Reviewed the potential pro forma impact of the Merger on the Company's
       earnings, cash flow and capitalization ratios;
 
  (10) Reviewed a draft of the Agreement dated April 18, 1997; and
 
  (11) Reviewed such other financial studies and analyses and took into
       account such other matters as we deemed necessary, including our
       assessment of general economic, market and monetary conditions.
 
  In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all financial and other information supplied or otherwise made
available to us, discussed with or reviewed by or for us or publicly
available, and we have not assumed any responsibility for making any
independent verification of such information or making any independent
evaluation or appraisal of any of the assets or liabilities of the Subject
Company or the Company or been furnished with any such evaluation or
appraisal. In particular, we have relied upon the estimates of the managements
of the Company and the Subject Company of the Expected Synergies and have
assumed that the Expected Synergies will be achieved. With respect to the
financial forecast information and the Expected Synergies furnished to or
discussed with us by the Subject Company and the Company, we have assumed that
they have been reasonably prepared and reflect the best currently available
estimates and judgment of the Subject Company's or the Company's management,
as the case may be, as to the expected future financial performance of the
Subject Company or the Company, as the case may be. In addition, we have not
assumed any obligation to conduct nor have we conducted any physical
inspection of the properties or facilities of the Subject Company or the
Company. We have assumed that the Merger will be consummated on terms
substantially similar to those set forth in the draft of the Agreement dated
April 18, 1997. We have further assumed that the Warrants to be issued as part
of the Transaction Consideration will contain terms not materially different
from, and otherwise in conformance with, those customary in similar
transactions.
 
  Our opinion is necessarily based upon market, economic and other conditions
as they exist and can be evaluated on, and on the information made available
to us as of, the date hereof.
 
  We are acting as financial advisor to the Company in connection with the
Merger and will receive a fee from the Company for our services. The Company
has agreed to indemnify us for certain liabilities arising out of our
engagement. Previously, we have performed investment banking and other
services for the Company and the Subject Company and have received customary
compensation for the rendering of such services. During 1996, we served as
lead manager to the Company in connection with the initial public offering of
Company Shares, and we worked actively with the Subject Company in connection
with a proposed initial public offering of the Shares. In addition, in the
ordinary course of our business, we may actively trade the Company Shares and
other securities of the Company, for our own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
  This opinion is for the use and benefit of the Board of Directors of the
Company. Our opinion does not address the merits of the underlying decision by
the Company to engage in the Merger, and does not constitute a recommendation
to any shareholder as to how such shareholder should vote on the proposed
Merger.
 
                                      3-2
<PAGE>
 
  We are not expressing any opinion herein as to the prices at which the
Company Shares will trade following the announcement or consummation of the
Merger.
 
  On the basis of, and subject to the foregoing, we are of the opinion that,
as of the date hereof, the Transaction Consideration is fair from a financial
point of view to the Company.
 
                                          Very truly yours,

Attn: Walter V. Stafford
 
Dear Mr. Stafford:
 
  CB Commercial Real Estate Services Group, Inc. ( the "Company"), CBC
Acquisition Corporation, a wholly owned subsidiary of the Company (the
"Acquisition Sub"), Koll Real Estate Services (the "Subject Company") and
certain related parties have entered into an agreement dated May 14, 1997 (the
"Merger Agreement") pursuant to which the Acquisition Sub will be merged with
and into the Subject Company (the "Merger"). In connection with the proposed
Merger, on April 22, 1997, we delivered an opinion to the Board of Directors
of the Company that, based on the terms set forth in the April 18, 1997 draft
of the Merger Agreement, the aggregate consideration to be paid by the Company
in the Merger was fair from a financial point of view to the Company.
 
  We hereby inform the Company that, based upon the final terms of the Merger
Agreement dated May 14, 1997, we would not have modified our opinion that the
aggregate consideration to be paid by the Company in the Merger is fair from a
financial point of view to the Company. In reaching such determination, we did
not undertake to review any documentation in addition to that set forth in our
opinion delivered to the Board of Directors of the Company on April 22, 1997,
nor did we provide the Board of Directors of the Company with a formal opinion
regarding the fairness of the aggregate consideration as set forth in the
final Merger Agreement. This letter does not constitute an opinion with
respect to the fairness of the aggregate consideration set forth in the final
Merger Agreement.
 
                                          Very truly yours,
 
                                          MERRILL LYNCH, PIERCE, FENNER & SMITH

                       DELAWARE GENERAL CORPORATION LAW
                                  SECTION 262
 
  APPRAISAL RIGHTS. (a) Any stockholder of a corporation of this State who
holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation,
who has otherwise complied with subsection (d) of this section and who has
neither voted in favor of the merger or consolidation nor consented thereto in
writing pursuant to (S) 228 of this title shall be entitled to an appraisal by
the Court of Chancery of the fair value of his shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a non-stock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a non-stock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
  (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to
be effected pursuant to (S)(S) 251 (other than a merger effected pursuant to
(S)251(g) of this title), 252, 254, 257, 258, 263 or 264 of this title:
 
    (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or (ii) held
  of record by more than 2,000 holders; and further provided that no
  appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the holders of the surviving corporation as
  provided in subsection (f) of (S) 251 of this title.
 
    (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series
  of stock of a constituent corporation if the holders thereof are required
  by the terms of an agreement of merger or consolidation pursuant to (S)(S)
  251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock
  anything except:
 
      a. Shares of stock of the corporation surviving or resulting from
    such merger or consolidation, or depository receipts in respect
    thereof;
 
      b. Shares of stock of any other corporation, or depository receipts
    in respect thereof, which shares of stock or depository receipts at the
    effective date of the merger or consolidation will be either listed on
    a national securities exchange or designated as a national market
    system security on an interdealer quotation system by the National
    Association of Securities Dealers, Inc. or held of record by more than
    2,000 holders;
 
      c. Cash in lieu of fractional shares or fractional depository
    receipts described in the foregoing subparagraphs a. and b. of this
    paragraph; or
 
      d. Any combination of the shares of stock, depository receipts and
    cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a., b. and c. of this
    paragraph.
 
    (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under (S) 253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall
  be available for the shares of the subsidiary Delaware corporation.
 
                                      4-1

  (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.
 
  (d) Appraisal rights shall be perfected as follows:
 
    (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsections (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of his shares shall deliver to the
  corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of his shares. A proxy or vote against the merger or
  consolidation shall not constitute such a demand. A stockholder electing to
  take such action must do so by a separate written demand as herein
  provided. Within 10 days after the effective date of such merger or
  consolidation, the surviving or resulting corporation shall notify each
  stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or
 
    (2) If the merger or consolidation was approved pursuant to (S) 228 or
  (S) 253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholders
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within twenty days after the date of
  mailing of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that if such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given; provided that,
  if the notice is given on or after the effective date of the merger or
  consolidation, the record date shall be such effective date. If no record
  date is fixed and the notice is given prior to the effective date, the
  record date shall be the close of business on the next day preceding the
  day on which the notice is given.
 
                                      4-2
<PAGE>
 
  (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied
with subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger
or consolidation, any stockholder shall have the right to withdraw his demand
for appraisal and to accept the terms offered upon the merger or
consolidation. Within 120 days after the effective date of the merger or
consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which
demands for appraisal have been received and the aggregate number of holders
of such shares. Such written statement shall be mailed to the stockholder
within 10 days after his written request for such a statement is received by
the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
  (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
  (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates
to submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
  (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court
may, in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on
the list filed by the surviving or resulting corporation pursuant to
subsection (f) of this section and who has submitted his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to
appraisal rights under this section.
 
  (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Court's decree may be enforced
as other decrees in the Court of
 
                                      4-3
<PAGE>
 
Chancery may be enforced, whether such surviving or resulting corporation be a
corporation of this State or of any state.
 
  (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
  (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal
of his demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.
 
  (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

Exchange Act of 1934.
 
4. STOCK
 
  The stock that may be issued pursuant to Options granted under the Plan
shall be shares of Common Stock, par value $0.01 per share, of CBC (the
"Stock"), which shares may be treasury shares or authorized but unissued
shares. The number of shares of Stock that may be issued pursuant to the
exercise of Options granted under the Plan shall not exceed in the aggregate
700,000 shares, which number of shares is subject to adjustment as hereinafter
provided in Section 18. If any Option expires or terminates for any reason
prior to exercise in full, the shares of Stock that were subject to the
unexercised portion of such Option shall be available for the grant of future
Options under the Plan.
 
5. ELIGIBILITY
 
  Options may be granted under the Plan to any employee or independent
contractor of CBC or a Subsidiary (including any contractor operating in the
form of a corporation, partnership, limited liability company or otherwise and
any employee or independent contractor such person who is an officer of CBC or

termination, grant Options in its sole and absolute discretion to any Eligible
Employee selected in writing by the Committee, on such terms and conditions as
the Committee may determine, including any terms or conditions which may be
necessary and appropriate to qualify such Options as "incentive stock options"
under Section 422 of the Code provided that no Eligible Employee may be
selected as an Optionee who is not identified as a key employee by CBC's Chief
Executive Officer. No grant or series of grants hereunder to an Optionee may
exceed 75,000 shares in any calendar year. The date on which the Committee
approves the grant of an Option shall be considered the date on which such
Option is granted unless the Committee determines otherwise. Options may be
granted but not exercised prior to stockholder approval and in the event
stockholder approval is not obtained on or before September 30, 1997 all such
options shall be null and void.
 
8. LIMITATIONS ON INCENTIVE STOCK OPTIONS
 
  An Option may, if so determined by the Committee, constitute an incentive
stock option to the extent that the aggregate fair market value (determined at
the time the option is granted) of the stock with respect to which incentive
stock options are exercisable for the first time by any Optionee during any
calendar year (under the Plan and all other stock option plans of CBC or any
Subsidiary) does not exceed $100,000.
 
                                      5-2
<PAGE>
 
9. OPTION AGREEMENTS
 
  All Options granted pursuant to the Plan shall be evidenced by written
agreements ("Option Agreements"), to be executed by CBC and by the Optionee,
in such form or forms and with such terms as the Committee shall from time to
time determine. Option Agreements covering Options granted from time to time
or at the same time need not contain similar provisions; provided however,
that no Option Agreements shall be inconsistent with any term of this Plan.
 
10. OPTION PRICE
 
  The purchase price of each share of Stock subject to an Option (the "Option
Price") shall be its fair market value on the date the Option is granted. In
the event that the Stock is listed on an established national or regional
stock exchange, is admitted to quotation on The Nasdaq Stock Market, or is
publicly traded in an established securities market, in determining the fair
market value of the Stock, the Committee shall use: the closing price of the
Stock on such exchange or System or in such market (the highest such closing
price if there is more than one such exchange or market) on the trading date
when the Option is granted; or, if there is no such closing price, then the
Committee shall use the mean between the highest bid and lowest asked prices
or between the high and low prices on such date; or, if no sale of the Stock
has been made on such day, on the next preceding day on which any such sale
shall have been made; or such other method as the Committee may determine.
 
11. TERM AND EXERCISE OF OPTIONS
 
  (a) Term. Each Option granted under the Plan shall terminate and all rights
to purchase shares thereunder shall cease upon a date fixed by the Committee
and stated in the Option Agreement. All options granted under the Plan shall
terminate no later than ten (10) years from the date of grant.
 
  (b) Option Period and Limitations on Exercise. Each Option shall be
exercisable, in whole or in part, at any time and from time to time during the
term of the Option, at such times, and with such conditions, as the Committee
shall determine and set forth in the related Option Agreement. Without
limiting the foregoing, the Committee, subject to the terms and conditions of
the Plan, may in its sole discretion provide that an Option may not be
exercised in whole or in part for any period or periods of time during which
such Option is outstanding; provided, however, that any such time limitation
on the exercise of an Option contained in any Option Agreement may be
rescinded, modified or waived by the Committee, in its sole discretion, at any
time and from time to time after the date of grant of such Option.
 
  (c) Method of Exercise and Payment. An Option may be exercised under such
rules as the Committee may establish from time-to-time by delivery to CBC of a
written notice of exercise on any business day, at the location specified from
time-to-time by CBC, which notice shall specify the number of shares with
respect to which the Option is being exercised, and shall be accompanied by
payment in full of the Option Price of the shares for which the Option is
being exercised. The minimum number of shares of Stock with respect to which
an Option may be exercised at any time shall be the lesser of 100 shares or
the maximum number of shares available for purchase under the Option at the
time of exercise. Payment of the Option Price for the shares of Stock
purchased pursuant to the exercise of an Option shall be made (i) by cashier's
check drawn on a major national bank or a wire transfer; (ii) with the consent
of the Committee, through the tender to CBC of shares of Stock, which shares
shall be valued, for purposes of determining the extent to which the Option
Price has been paid thereby, at their fair market value (determined by the
Committee in the manner described in Section 10 above) on the date of
exercise; or (iii) by a combination of the methods described in (i) and (ii).
If shares of Stock are surrendered by an officer of CBC who is subject to
Section 16(b) of the Securities Exchange Act of 1934 as payment of the Option
Price and the Stock surrendered was acquired pursuant to an option to acquire
CBC common stock and such acquisition was not an exempt transaction under
Section 16 of the Securities Exchange Act of 1934, then six (6) months must
have elapsed since the date of grant of such option. The payment in full of
the Option Price shall be deemed to have been made with the written notice of
exercise provided the notice of exercise directs that the stock certificate or
certificates for the shares of Stock for which
 
                                      5-3
<PAGE>
 
the Option is exercised be delivered to a licensed broker acceptable to CBC as
the agent for the individual exercising the Option and, at the time such stock
certificate or certificates are delivered, the broker tenders to CBC cash (or
cash equivalents acceptable to CBC) equal to the Option Price for the shares
of Stock purchased plus the amount (if any) of federal and/or other taxes
which CBC, in its discretion, requires to be withheld with respect to the
exercise of the Option. An attempt to exercise any Option granted hereunder
other than as set forth above shall be invalid and of no force and effect.
Promptly after the exercise of an Option and the payment or deemed payment in
full of the Option Price therefor and any applicable withholding taxes, the
individual exercising the Option shall be entitled to the issuance of a Stock
certificate or certificates evidencing his or her ownership of such shares. A
separate Stock certificate or certificates shall be issued for any shares
purchased pursuant to the exercise of an Option which is an incentive stock
option, which certificate or certificates shall not include any shares which
were purchased pursuant to the exercise of an Option which is not an incentive
stock option. An individual holding or exercising an Option shall have none of
the rights of a stockholder until the shares of Stock covered thereby are
fully paid and issued, and except as provided in Section 18 below, no
adjustment shall be made for dividends or other rights for which the record
date is prior to the date of such issuance.
 
  (d) Withholding Taxes. CBC shall have the right, as a condition to the
exercise of any Option, to withhold from any amount payable to the Optionee,
or require the Optionee to remit to CBC, an amount (in the form of a cashier's
check or wire transfer) sufficient to satisfy any federal, state, local or
foreign withholding tax requirements imposed with respect to the exercise of
the Option or the issuance of shares of Stock pursuant to the option as
determined by the Committee in its discretion.
 
12. TRANSFERABILITY OF OPTIONS
 
  During the lifetime of an Optionee, only such Optionee (or, in the event of
legal incapacity or incompetency, the Optionee's guardian or legal
representative) may exercise the Option. No Option shall be assignable or
transferable by the Optionee to whom it is granted, other than by will, the
laws of descent and distribution, or pursuant to a qualified domestic
relations order as defined in Section 414 of the Code, and no Option shall be
pledged or hypothecated (by operation of law or otherwise), or subject to
execution, attachment or similar process.
 
13. TERMINATION OF SERVICE OR EMPLOYMENT
 
  If an Optionee ceases to be an employee or independent contractor of CBC or
its Subsidiaries for any reason other than death or "permanent and total
disability" (within the meaning of Section 22(e)(3) of the Code), any Option
granted to such Optionee pursuant to the Plan shall terminate 30 days after
the date of such cessation unless earlier terminated pursuant to Section
11.(a) above, and such Optionee shall have no further right to purchase shares
of Stock pursuant to such Option; provided, however, that the Committee may
provide, by inclusion of appropriate language in any Option Agreement, that an
Optionee may (subject to the general limitations on exercise set forth in
Section 11.(b)), in the event he or she ceases to be an employee or
independent contractor, exercise an Option, in whole or in part, at a time
subsequent to such cessation and prior to termination of the Option as
provided in Section 11.(a) above, either subject to or without regard to any
installment limitation on exercise imposed pursuant to Section 11.(b) above.
Whether a leave of absence or leave on military or government service shall
cause an Optionee to cease to be an employee or independent contractor shall
be determined by the Committee, which determination shall be final and
conclusive. For purposes of the Plan, an Optionee shall not cease to be an
employee or independent contractor if his or her employment or service
terminates, but the Optionee is immediately thereafter employed with CBC or
any Subsidiary as an employee or independent contractor.
 
14. RIGHTS IN THE EVENT OF DEATH OR DISABILITY
 
  (a) Death. If the Optionee dies while employed by or in the service of CBC
or a Subsidiary, except as is otherwise provided in the Option Agreement
relating to such Option, the executors, administrators, heirs, legatees
 
                                      5-4
<PAGE>
 
or distributees (as applicable) of such Optionee's estate shall have the right
(subject to the general limitations on exercise set forth in Section 11.(b)
above), prior to termination of the Option as provided in Section 11.(a)
above, to exercise any Option held by such Optionee at the date of such
Optionee's death to the extent the Option was exercisable on such date, on
such terms as the Committee may provide in the Option Agreement.
 
  (b) Disability. If the Optionee ceases to be an employee or independent
contractor of CBC or its Subsidiaries by reason of "permanent and total
disability" (within the meaning of Section 22(e)(3) of the Code), then such
Optionee shall have the right (subject to the general limitations on exercise
set forth in Section 11.(b) above), within the earlier of (i) one year after
such cessation, or (ii) the termination of the Option as provided in Section
11.(a) above, to exercise, in whole or in part, any Option held by such
Optionee at the date of such cessation on such terms as the Committee may
provide in the Option Agreement, provided, however, that the Committee may
provide, by inclusion of appropriate language in the Option Agreement, that
the Optionee may (subject to the general limitations on exercise set forth in
Section 11.(b) above), in the event he or she ceases to be an employee or
independent contractor by reason of "permanent and total disability" (within
the meaning of Section 22(e)(3) of the Code), exercise an Option, in whole or
in part, at any time subsequent to such termination and prior to termination
of the Option as provided in Section 11.(a) above, either subject to or
without regard to any installment limitation on exercise imposed pursuant to
Section 11.(b) above. Whether an Optionee has suffered "permanent and total
disability" for purposes of this Plan shall be determined by the Committee,
which determination shall be final and conclusive.
 
15. USE OF PROCEEDS
 
  The proceeds received by CBC from the sale of Stock pursuant to Options
granted under the Plan shall constitute general funds of CBC.
 
16. REQUIREMENTS OF LAW
 
  (a) Violations of Law. CBC shall not be required to sell or issue any shares
of Stock under any Option if the sale or issuance of such shares would
constitute a violation by the individual exercising the Option or CBC of any
provisions of any law or regulation of any governmental authority, including
without limitation any federal or state securities laws or regulations.
Specifically in connection with the Securities Act of 1933 (as now in effect
or as hereafter amended), upon exercise of any Option, unless a registration
statement under such Act is in effect with respect to the shares of Stock
covered by such Option, CBC shall not be required to sell or issue such Shares
unless the Committee has received evidence satisfactory to it that the holder
of such Option may acquire such shares pursuant to an exemption from
registration under such Act. Any determination in this connection by the
Committee shall be final, binding, and conclusive. CBC may, but shall in no
event be obligated to, register any securities covered hereby pursuant to the
Securities Act of 1933 (as now in effect or as hereafter amended). CBC shall
not be obligated to take any affirmative action in order to cause the exercise
of an Option or the issuance of shares pursuant thereto to comply with any law
or regulation of any governmental authority. As to any jurisdiction that
expressly imposes the requirement that an Option shall not be exercisable
unless and until the shares of stock covered by such Option are registered or
are subject to an available exemption from registration, the exercise of such
Option (under circumstances in which the laws of such jurisdiction apply)
shall be deemed conditioned upon the effectiveness of such registration or the
availability of such an exemption.
 
  (b) Compliance with Rule 16b-3. The Plan is intended to comply with Rule
16b-3 or its successor rule, promulgated under the Securities Exchange Act of
1934. With respect to persons subject to Section 16 of the Securities Exchange
Act of 1934, any provision of the Plan or action of the Plan administrators
that is inconsistent with such Rule shall be deemed null and void to the
extent permitted by law and deemed advisable by the Committee.
 
17. AMENDMENT AND TERMINATION OF THE PLAN
 
  The Board or the Committee may, at any time and from time to time, amend,
suspend or terminate the Plan as to any shares of Stock as to which Options
have not been granted. The foregoing notwithstanding no
 
                                      5-5
<PAGE>
 
amendment shall, without the approval of the stockholders of CBC, (a)
materially change the requirements as to the eligibility to receive options,
(b) increase the maximum number of shares subject to the Plan (except as
provided in Section 18), (c) change the minimum Option Price (except as
provided in Section 18), (d) increase the maximum period during which options
may be exercised, (e) extend the term of the Plan, or (f) materially increase
the benefits accruing to any Optionee under the Plan. Except as permitted
under Section 18 hereof, no amendment, suspension or termination of the Plan
shall, without the consent of the holder of the Option, materially alter or
materially impair rights or obligations under any Option theretofore granted
under the Plan.
 
18. EFFECT OF CHANGES IN CAPITALIZATION
 
  (a) Changes in Stock. If the outstanding shares of Stock are increased or
decreased or changed into or exchanged for a different number or kind of
shares or other securities of CBC by reason of any recapitalization,
reclassification, stock split-up, combination of shares, exchange of shares,
stock dividend or other distribution payable in capital stock, or other
increase or decrease affecting such outstanding shares generally that is
effected without receipt of consideration by CBC, occurring after the
effective date of the Plan, the number and kinds of shares for the purchase of
which Options may be granted under the Plan shall be adjusted proportionately
and accordingly by the Committee. In addition, the number and kind of shares
for which Options are outstanding shall be adjusted proportionately and
accordingly so that the proportionate ownership interest of the holder of the
Option immediately following such event shall, to the extent practicable, be
the same as immediately prior to such event. Any such adjustment in
outstanding Options shall not change the aggregate Option Price payable with
respect to shares subject to the unexercised portion of the Option outstanding
but shall include a corresponding proportionate adjustment in the Option Price
per share. If there is a distribution payable in the capital stock of a
Subsidiary ("Spin-off Shares"), to the extent consistent with Treasury
Regulation Section 1.425-1(a)(6) or the corresponding provision of any
subsequent regulation, each outstanding Option shall thereafter additionally
pertain to the number of Spin-off Shares which would have been received if the
Optionee had been the holder on the distribution date of the number of shares
that are subject to the Option at the time of such distribution, and the
aggregate Option Price of the Option shall be allocated between the Spin-off
Shares and the Stock in proportion to the relative fair market values of a
Spin-off Share and a share of Stock immediately after the distribution of
Spin-off Shares.
 
  (b) Reorganization in Which CBC Is the Surviving Company. If CBC shall be
the surviving company in any reorganization, merger, or consolidation of CBC
with one or more other companies, any Option theretofore granted pursuant to
the Plan shall pertain to and apply to the securities to which a holder of the
number of shares of Stock subject to such Option would have been entitled
immediately following such reorganization, merger, or consolidation, with a
corresponding proportionate adjustment of the Option Price per share so that
the aggregate Option Price thereafter shall be the same as the aggregate
Option Price of the shares subject to the Option immediately prior to such
reorganization, merger, or consolidation.
 
  (c) Reorganization in Which CBC Is Not the Surviving Company; Sale of Assets
or Stock. Upon the dissolution or liquidation of CBC, or upon a merger,
consolidation or reorganization of CBC with one or more other companies in
which CBC is not the surviving company, or upon a sale of substantially all of
the assets of CBC to another company, or upon any transaction (including,
without limitation, a merger or reorganization in which CBC is the surviving
company) approved by the Board of Directors after February 4, 1997 which
results in any person or entity owning twenty-five percent (25%) or more of
the combined voting power of all classes of stock of CBC, the Plan and all
Options outstanding hereunder shall terminate, except to the extent provision
is made in writing in connection with such transaction for the continuation of
the Plan and/or the assumption of the Options theretofore granted, or for the
substitution for such Options of new options covering the stock of a successor
company, or a parent or subsidiary thereof, with appropriate adjustments as to
the number and kinds of shares and exercise prices, in which event the Plan
and Options theretofore granted shall continue in the manner and under the
terms so provided. In the event of any such termination of the Plan, each
individual holding an Option shall have the right immediately prior to the
occurrence of such termination and during such period occurring prior to such
termination as the Committee in its sole discretion shall determine and
designate, to
 
                                      5-6
<PAGE>
 
exercise such Option in whole or in part, whether or not such Option was
otherwise exercisable at the time such termination occurs and without regard
to any installment limitation on exercise imposed pursuant to Section 11.(b)
above. The Committee shall send written notice of an event that will result in
such a termination to all individuals who hold Options not later than the time
at which CBC gives notice thereof to its stockholders.
 
  (d) Adjustments. Adjustments under this Section 18 related to stock or
securities of CBC shall be made by the Committee, whose determination in that
respect shall be final, binding, and conclusive. No fractional shares of Stock
or units of other securities shall be issued pursuant to any such adjustment,
and any fractions resulting from any such adjustment shall be eliminated in
each case by rounding downward to the nearest whole share or unit.
 
  (e) No Limitations on CBC. The grant of an Option pursuant to the Plan shall
not affect or limit in any way the right or power of CBC to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structure or to merge, consolidate, dissolve or liquidate, or to sell or
transfer all or any part of its business or assets.
 
19. DISCLAIMER OF RIGHTS
 
  No provision in the Plan or in any Option granted or Option Agreement
entered into pursuant to the Plan shall be construed to confer upon any
individual the right to remain in the employ or service of CBC or any
Subsidiary, or to interfere in any way with the right and authority of CBC or
any Subsidiary either to increase or decrease the compensation of any
individual at any time, or to terminate any employment or other relationship
between any individual and CBC or any Subsidiary with or without cause.
 
20. NON-EXCLUSIVITY OF THE PLAN
 
  The adoption of the Plan shall not be construed as creating any limitations
upon the right and authority of the Committee to adopt such other incentive
compensation arrangements (which arrangements may be applicable either
generally to a class or classes of individuals or specifically to a particular
individual or individuals) as the Committee in its discretion determines
desirable, including, without limitation, the granting of stock options
otherwise than under the Plan.

to purchase the maximum number of whole shares of Stock which can be purchased
with the amount of the Participant's Compensation which is withheld during
each Purchase Period.
 
  (c) Once enrolled, a Participant will continue to participate in the Plan
for each succeeding Purchase Period until he or she terminates participation
or ceases to qualify as an Eligible Employee. A Participant who withdraws from
the Plan in accordance with Section 9 may again become a Participant, if he or
she then is an Eligible Employee, by following the procedure described in
Section 5(a).

hundred percent (100%) of the Fair Market Value of such share on the last

percent (100%) of the Fair Market Value of such share on the last trading day
before the last day of the Purchase Period.
 
  SECTION 7. EMPLOYEE CONTRIBUTIONS.
 
  A Participant may purchase shares of Stock solely by means of payroll
deductions. Payroll deductions, as designated by the Participant pursuant to
Section 5(a), shall commence with the first paycheck issued during the
Purchase Period and shall be deducted from each subsequent paycheck throughout
the Purchase Period. A Participant may not increase or decrease the rate of
payroll withholding during the Purchase Period, but a Participant may elect to
terminate future payroll withholding at any time during a Purchase Period by
filing a new participation agreement with the Plan Administrator. Such
termination will be effective no later than the first day of the second
payroll period which begins following the receipt of the new participation
agreement.
 
  SECTION 8. PLAN ACCOUNTS; PURCHASE OF SHARES.
 
  (a) The Company will maintain a Plan Account on its books in the name of
each Participant. At the close of each pay period, the amount deducted from
the Participant's Compensation will be credited to the Participant's Plan
Account.
 
  (b) As of the last day of each Purchase Period, the amount then in the
Participant's Plan Account will be divided by the Purchase Price, and the
number of whole shares which results (subject to the limitations described in
Sections 8(c) and 14) shall be purchased from the Company with the funds in
the Participant's Plan Account. Foreign currencies will be converted to U.S.
dollars based on the foreign currency exchange rate as quoted in The Wall
Street Journal on the last day of the Purchase Period. Share certificates
representing the number of shares of Stock so purchased shall be delivered to
the Participant.
 
  (c) In the event that the aggregate number of shares which all Participants
elect to purchase during a Purchase Period shall exceed the number of shares
remaining available for issuance under the Plan, then the number of shares to
which each Participant shall become entitled shall be determined by
multiplying the number of shares available for issuance by a fraction the
numerator of which is the sum of the number of shares the Participant has
elected to purchase pursuant to Section 5, and the denominator of which is the
sum of the number of shares which all employees have elected to purchase
pursuant to Section 5. Any cash amount remaining in the Participant's Plan
Account under these circumstances shall be refunded to the Participant, with
such payment to include simple interest at the rate of 5% per annum on the
amount of the refund.
 
  (d) Any amount remaining in the Participant's Plan Account caused by a
surplus due to fractional shares after deducting the amount of the Purchase
Price for the number of whole shares issued to the Participant shall be
carried over in the Participant's Plan Account for the succeeding Purchase
Period, without interest. Except as provided in Section 8(c), any amount
remaining in the Participant's Plan Account caused by anything other than a
surplus due to fractional shares shall be refunded to the Participant in cash,
without interest.
 
                                      6-3
<PAGE>
 
  (e) As soon as practicable following the end of each Purchase Period, the
Company shall deliver to each Participant a Plan Account statement setting
forth the amount of payroll deductions, the purchase price, the number of
shares purchased and the remaining cash balance, if any.
 
  SECTION 9. WITHDRAWAL FROM THE PLAN.
 
  A Participant may elect to withdraw (or not withdraw) from participation in
a Purchase Period at any time up to the last day of the Purchase Period by
filing the prescribed form with the Plan Administrator. As soon as practicable
after a withdrawal, payroll deductions shall cease and all amounts credited to
the Participant's Plan Account will be refunded in cash, without interest. A
Participant who has withdrawn from a Purchase Period shall not be a
Participant in future Purchase Periods, unless he or she again enrolls in
accordance with the provisions of Section 5.
 
  SECTION 10. TAXES.
 
  The Participant shall make such arrangements as the Company may require for
the satisfaction of any federal, state, local or foreign tax obligations that
may arise in connection with the disposition of the Stock acquired under the
Plan. These arrangements may include, in the Company's sole discretion,
withholding (or tendering back) of shares of Stock, or withholding amounts
from the Participant's compensation.
 
  SECTION 11. EFFECT OF TERMINATION OF EMPLOYMENT OR DEATH.
 
  (a) Termination of employment as an Eligible Employee for any reason,
including death, shall be treated as an automatic withdrawal from the Plan
under Section 9. A transfer from one Participating Company to another shall
not be treated as a termination of employment.
 
  (b) A Participant may file a written designation of a beneficiary who is to
receive any shares and cash, if any, from the Participant's Account under the
Plan in the event of such Participant's death subsequent to the purchase of
shares but prior to delivery to him or her of such shares and cash. In
addition, a Participant may file a written designation of a beneficiary who is
to receive any cash from the Participant's Account under the Plan in the event
of such Participant's death prior to the last day of a Purchase Period.
 
  (c) Such designation of beneficiary may be changed by the Participant at any
time by written notice. In the event of the death of a Participant in the
absence of a valid designation of a beneficiary who is living at the time of
such Participant's death, the Company shall deliver such shares and/or cash in
accordance with the Participant's designation of beneficiaries under the
Company's Capital Appreciation Plan; or, in the absence of such designation,
to the executor or administrator of the estate of the Participant; or if no
such executor or administrator has been appointed (to the knowledge of the
Company), the Company, in its discretion, may deliver such shares and/or cash
to the spouse or to any one or more dependents or relatives of the
Participant; or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.
 
  SECTION 12. RIGHTS NOT TRANSFERABLE.
 
  The rights or interests of any Participant in the Plan, or in any Stock or
moneys to which he or she may be entitled under the Plan, shall not be
transferable by voluntary or involuntary assignment or by operation of law, or
by any other manner other than as permitted by the Code or by will or the laws
of descent and distribution. If a Participant in any manner attempts to
transfer, assign or otherwise encumber his or her rights or interest under the
Plan, other than as permitted by the Code or by will or the laws of descent
and distribution, such act shall be treated as an automatic withdrawal under
Section 9.
 
  SECTION 13. RECAPITALIZATION, ETC.
 
  (a) The aggregate number of shares of Stock offered under the Plan, the
number and price of shares which any Participant has elected to purchase
pursuant to Section 5 shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Stock resulting from a subdivision
or consolidation of shares or any other capital adjustment, the payment of a
stock dividend, or other increase or decrease in such shares effected without
receipt of consideration by the Company.
 
                                      6-4
<PAGE>
 
  (b) In the event of a dissolution or liquidation of the Company, or a merger
or consolidation to which the Company is a constituent but not the surviving
corporation, this Plan shall terminate, unless the plan of merger,
consolidation or reorganization provides otherwise, and all amounts which each
Participant has paid towards the Purchase Price of Stock hereunder shall be
refunded, without interest.
 
  (c) The Plan shall in no event be construed to restrict in any way the
Company's right to undertake a dissolution, liquidation, merger, consolidation
or other reorganization.
 
  SECTION 14. LIMITATION ON STOCK OWNERSHIP.
 
  Notwithstanding any provision herein to the contrary, no Participant shall
be permitted to elect to participate in the Plan (i) if such Participant,
immediately after his or her election to participate, would own stock
possessing five percent (5%) or more of the total combined voting power or
value of all classes of stock of the Company or any parent or Subsidiary of
the Company, or (ii) if under the terms of the Plan the rights of the Employee
to purchase Stock under this Plan and all other qualified employee stock
purchase plans of the Company or its Subsidiaries would accrue at a rate which
exceeds twenty-five thousand dollars ($25,000) of the Fair Market Value of
such Stock (determined at the time such right is granted) for each calendar
year for which such right is outstanding at any time. For purposes of this
Section 14, ownership of stock shall be determined by the attribution rules of
Section 424(d) of the Code, and Participants shall be considered to own any
stock which they have a right to purchase under this or any other stock plan.
 
  SECTION 15. NO RIGHTS AS AN EMPLOYEE.
 
  Nothing in the Plan shall be construed to give any person the right to
remain in the employ of a Participating Company. Each Participating Company
reserves the right to terminate the employment of any person at any time and
for any reason or for no reason.
 
  SECTION 16. RIGHTS AS A STOCKHOLDER.
 
  A Participant shall have no rights as a stockholder with respect to any
shares he or she may have a right to purchase under the Plan until the date of
issuance of a stock certificate to the Participant for shares of Stock issued
pursuant to the Plan.
 
  SECTION 17. USE OF FUNDS.
 
  All payroll deductions received or held by the Company under the Plan may be
used by the Company for any corporate purpose, and the Company shall not be
obligated to segregate such payroll deductions in separate accounts.
 
  SECTION 18. AMENDMENT, EXTENSION OR TERMINATION OF THE PLAN.
 
  The Board of Directors shall have the right to amend, modify or terminate
the Plan at any time without notice. The Board of Directors may extend the
Plan for up to an additional eight Purchase Periods and may allocate an
additional 150,000 shares of Stock for offering pursuant to the Plan with
respect to each such Purchase Period. This 150,000 limit shall be subject to
adjustment as provided in Section 13. An amendment of the Plan shall be
subject to stockholder approval only to the extent required by applicable
laws, regulations or rules. Amendments to the Plan to comply with the
requirements of a foreign country may be adopted by the Plan Administrator to
the extent those amendments do not prevent the Plan from satisfying the
requirements of Section 423 of the Code.
 
  SECTION 19. GOVERNING LAW.
 
  The Plan shall be governed by, and construed and interpreted in accordance

issued Shares or treasury Shares. The Company, during the term of the Plan,
shall at all times reserve and keep available sufficient Shares to satisfy the

SECTION 6. TERMS AND CONDITIONS OF PURCHASES
 
  (a) Stock Purchase Agreement. Each purchase of Shares under the Plan shall
be evidenced by a Stock Purchase Agreement between the Offeree and the
Company. Such purchase shall be subject to all applicable terms and conditions
of the Plan and may be subject to any other terms and conditions which are not

Purchase Agreements entered into under the Plan need not be identical.
 
  (b) Duration of Offers and Nontransferability of Rights. Any right to
purchase Shares under the Plan shall automatically expire if not exercised by
the Offeree within 180 days after the grant of such right was communicated to
the Offeree by the Committee. Such right shall not be transferable and shall
be exercisable
 
                                      8-2
<PAGE>
 
only by the Offeree to whom such right was granted. An Offeree may elect to
purchase less than all of the Shares offered to him or her under the Plan.
 
  (c) Purchase Price. The Purchase Price of Shares to be offered under the
Plan shall be equal to the greater of:
 
    (i) $10 per Share; or
 
    (ii) 100% of the Fair Market Value of such Shares at the time of the
  offer.
 
  The Purchase Price shall be payable in a form described in Section 7.
 
  (d) Withholding Taxes. As a condition to the purchase of Shares, the Offeree
shall make such arrangements as the Committee may require for the satisfaction
of any federal, state, local or foreign withholding tax obligations that may
arise in connection with such purchase.
 
  (e) Restrictions on Transfer of Shares. The Shares purchased under the Plan
shall be subject to such forfeiture conditions, rights of repurchase and other
transfer restrictions as the Committee may determine. Such restrictions shall
be set forth in the applicable Stock Purchase Agreement and shall apply in
addition to any restrictions that may apply to holders of Shares generally.
Shares purchased under the Plan that remain subject to forfeiture shall be
held in escrow by an escrow agent appointed by the Company.
 
  (f) Documentation. Any other provision of the Plan notwithstanding, any
purchase of Shares under the Plan shall be subject to the following
requirements unless the Committee otherwise determines:
 
    (i) The form of Stock Purchase Agreement attached to this Plan as Exhibit
  A shall be used for such purchase; and
 
    (ii) The form of Joint Escrow Instructions attached to this Plan as
  Exhibit B shall be applicable to such Shares (to the extent they remain
  subject to forfeiture).
 
SECTION 7. PAYMENT FOR SHARES
 
  (a) General Rule. The entire Purchase Price of Shares issued under the Plan
shall be paid in lawful money of the United States of America at the time when
such Shares are purchased, except as provided in Subsection (b) below.
 
  (b) Promissory Note. All or a portion of the Purchase Price of Shares issued
under the Plan may be paid with a full-recourse promissory note, except that
the par value of such Shares shall be paid in lawful money of the United
States of America. The Committee shall specify the term, interest rate,
amortization requirements (if any) and other provisions of such note, provided
that:
 
    (i) The Shares being purchased are pledged as security for payment of the
  principal amount of the promissory note and interest thereon;
 
    (ii) The interest rate payable under the terms of the promissory note
  shall not be less than the minimum rate (if any) required to avoid the
  imputation of additional interest under the Internal Revenue Code of 1986,
  as amended; and
 
    (iii) In the case of a purchase of Shares under the Plan during 1996, the
  form of promissory note attached to this Plan as Exhibit C and the form of
  Security Agreement attached to this Plan as Exhibit D shall be used.
 
SECTION 8. ADJUSTMENT OF SHARES
 
  In the event of a subdivision of the outstanding Stock, a declaration of a
dividend payable in Shares, a combination or consolidation of the outstanding
Stock into a lesser number of Shares, a recapitalization, a
 
                                      8-3
<PAGE>
 
reclassification or a similar occurrence, the Committee shall make appropriate
adjustments in the number of Shares available for future grants under Section
5.
 
SECTION 9. SECURITIES LAWS
 
  Shares shall not be issued under the Plan unless the issuance and delivery
of such Shares comply with (or are exempt from) all applicable requirements of
law, including (without limitation) the Securities Act of 1933, as amended,
the rules and regulations promulgated thereunder, state securities laws and
regulations, and the regulations of any stock exchange or other securities
market on which the Company's securities may then be traded.
 
SECTION 10. NO EMPLOYMENT RIGHTS
 
  No provision of the Plan, nor any right granted under the Plan, shall be
construed to give any person any right to become, to be treated as, or to
remain an Executive. The Company and its Subsidiaries reserve the right to
terminate any person's service at any time and for any reason.
 
SECTION 11. DURATION AND AMENDMENTS
 
  (a) Term of the Plan. The Plan, as set forth herein, shall become effective
upon its adoption by the Committee. The Committee may amend, suspend or
terminate the Plan at any time and for any reason.
 
  (b) Effect of Amendment or Termination. No Shares shall be issued under the
Plan after the termination thereof. The termination of the Plan, or any
amendment thereof, shall not affect any Share previously issued under the
Plan.
 
SECTION 12. EXECUTION
 
  To record the adoption of the Amended and Restated Plan by the Committee,
the Company has caused its authorized officer to execute the same.

                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law provides for the
indemnification of officers, directors and other corporate agents in terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act of 1933, as amended (the "Act"). The statute provides that
indemnification pursuant to its provisions is not exclusive of other rights of
indemnification to which a person may be entitled under any bylaw, agreement,
vote of stockholders or disinterested directors, or otherwise. The Registrant
Fourth Amended and Restated Certificate of Incorporation (Exhibit 3(i) hereto)
provides for the indemnification of the Registrant's directors and officers to
the extent and under the circumstances permitted by the Delaware General
Corporation Law.
 
  The Registrant has entered into separate indemnification agreements with its
directors that could require the Registrant, among other things, to indemnify
the directors against liabilities that may arise by reason of their status or
service as directors and to advance their expenses incurred as a result of any
proceeding against them. The Registrant has obtained directors' and officers'
liability insurance that may cover, among other things, liabilities under the
federal securities laws.

ITEM 22. UNDERTAKINGS
 
  (1) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
                                     II-4
<PAGE>
 
  (2) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),
the Registrant undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other Items of the applicable form.
 
  (3) The Registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (2) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415 under the Securities Act of
1933, will be filed as a part of an amendment to the registration statement
and will not be used until such amendment is effective, and that, for purposes
of determining any liability under the Securities Act of 1933, each such post-
effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
  (4) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
 
  (5) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  (6) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

           Re:  Agreement and Plan of Reorganization
                dated as of May 14, 1997, by and among
                CB Commercial Real Estate Services Group, Inc.,
                CBC Acquisition Corporation, Koll Real Estate Services,
                and certain Shareholders of Koll Real Estate Services
                ---------------------------------------------------------

Ladies and Gentlemen:

          We have acted as counsel to Koll Real Estate Services, a Delaware
corporation ("KRES"), and certain holders of the KRES Common in connection with
the above-referenced agreement (the "Merger Agreement") and the transactions
contemplated thereby. Pursuant to the Merger Agreement, KRES will be merged with
CBC Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary
of CB Commercial Real Estate Services Group, Inc., a Delaware corporation
("CBC"), as a result of which KRES will become a wholly-owned subsidiary of CBC.
This opinion is delivered to you pursuant to Section 11.3(g) of the Merger
Agreement. Terms defined in the Merger Agreement and not otherwise defined
herein are used herein with the meanings set forth in the Merger Agreement.

          Documents Reviewed and Factual Matters.  In order to formulate and
          --------------------------------------                            
render our opinion as set forth herein, we have examined the originals or
copies, certified or otherwise identified, to our satisfaction, of the
following:

               1.   The Merger Agreement, including all Exhibits attached
          thereto;

               2.   The Certificate of Incorporation and Bylaws, together with
          any amendments thereto, of KRES;

Page 2


               3.   The minutes of meetings of the Board of Directors and the
          Stockholders of KRES and the stock record book of KRES; and

               4.   The representation letter of KRES in favor of Riordan &
          McKinzie dated July 24, 1997 (the "KRES Letter"), and the exhibits
          thereto which include representation letters of the stockholders of
          KRES (the "KRES Stockholder Letters"), and the representation letter
          of CBC.

          We also have conferred with such officers and directors of KRES and
have reviewed such corporate and other records, documents, certificates and
other papers as we deemed necessary to render this opinion.

          As to certain questions of fact material to our opinion, we have
relied upon the representations by KRES contained in the KRES Letter and by the
stockholders of KRES in the KRES Stockholder Letters.  Among the representations
made by the stockholders of KRES is a representation that they have no present
plan or intention to sell or otherwise dispose of the CBC Common they will
receive in the Merger.  There can be no assurance that the stockholders of KRES
will not, pursuant to a present plan or intention, sell or otherwise dispose of
the CBC Common they receive in the Merger.  If a sufficient amount of CBC
Common, in the aggregate, is sold or otherwise disposed of by the stockholders
of KRES pursuant to a present plan or intention, then the Merger will be a
taxable transaction to all of the stockholders of KRES, whether or not they sold
CBC Common received in the Merger.

          Additionally, among the representations made by KRES is a
representation that the fair market value of the Warrants and any other property
received by the holders of KRES Common in connection with the Merger does not
constitute more than twenty percent (20%) of the total fair market value of all
consideration given by CBC in exchange for all outstanding KRES Common on the
Effective Time.  If the fair market value of the Warrants and other
consideration exceeds twenty percent (20%) of the total fair market value of the
outstanding KRES Common, then the Merger would be a taxable transaction to all
of the stockholders of KRES, whether or not they received Warrants in the
Merger.


          Assumptions.  For purposes of rendering the opinions set forth herein,
          -----------                                                           
we have made and relied, without independent inquiry, upon the following
assumptions:
<PAGE>
 
Koll Real Estate Services and

Page 3

               1.   The due authorization, execution and delivery of any
          documents referred to herein by any party other than KRES; the
          genuineness of all signatures on original and certified copies; and
          the conformity to original or certified copies of all copies submitted
          to us as conformed or reproduction copies thereof.

               2.   The Merger, as contemplated in the Merger Agreement, will
          constitute a valid statutory merger in accordance with applicable
          state law .

          Opinions of Counsel.  The existing Treasury Regulations promulgated
          -------------------                                                
under sections 354 and 355 of the Code treat the Warrants as neither stock nor
securities for reorganization purposes.  However, under applicable case law
preceding such regulations, the Warrants could be treated as securities for
reorganization purposes.  In December 1996, the Department of the Treasury
proposed Treasury Regulations which would treat the Warrants as securities
without a principal amount.  As presently drafted, such regulations would apply
to exchanges occurring on or after sixty (60) days following its adoption.  Such
Treasury Regulations, however, have not yet been adopted.  Thus, at the present
time, it is not clear whether the Warrants received by the KRES stockholders
will be treated for purposes of this Merger as "stock or securities" or as
property other than "stock or securities."

          Based upon the foregoing and subject to the qualifications and
conditions expressed herein, we are of the opinion that, for federal income tax
purposes:

               1.   The Merger will qualify as a "reorganization" as defined in
          Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code.

               2.   No gain or loss will be recognized by KRES, Acquisition
          Corporation or CBC as a result of the Merger.

               3.   A KRES stockholder who receives a cash payment in lieu of a
          fractional share of CBC Common will be treated as if such fractional
          share were distributed in the Merger and then redeemed by CBC, and
          should recognize capital gain or loss measured by the difference
          between the amount of cash received and the stockholder's basis in the
          fractional share (which will be a pro rata portion of the
          stockholder's basis in the CBC Common received in the Merger),
          provided that such stockholder's KRES Common is held as a capital
          asset on the Effective Date.

          Based upon the foregoing and subject to the qualifications and
conditions expressed herein, and PROVIDED THAT THE WARRANTS ARE TREATED FOR
PURPOSES OF THIS MERGER AS "STOCK OR SECURITIES" (AS MORE PARTICULARLY DESCRIBED
ABOVE), we are of the further opinion that, for federal income tax purposes:

               1.   No gain or loss will be recognized by the holders of KRES
          Common who exchange all of their KRES Common for CBC Common and/or
          Warrants in the Merger.
    
               2.   The aggregate basis of the CBC Common received by each
          holder of KRES Common will be the same as the aggregate basis of such
          holder in KRES Common exchanged therefor in the Merger.
    
               3.   The aggregate basis of the Warrants received by each holder
          of KRES Common will equal zero.
    
               4.   The holding period of the CBC Common and Warrants received
          by a holder of KRES Common will include the period during which such
          holder held KRES Common exchanged therefor in the Merger, provided
          that such stock was held as a capital asset on the Effective Date.

          If, however, the Warrants are treated for purposes of the Merger as
property other than "stock or securities" as set forth in the existing Treasury
Regulations, then:  (a) holders of KRES Common will recognize gain upon receipt
of Warrants in the Merger exchange in an amount equal to the lesser of (i) the
excess of the fair market value of the CBC Common and Warrants received over the
basis of such stockholder in the KRES Common exchanged in the Merger, or (ii)
the fair market value of such Warrants received in the Merger; (b) the aggregate
basis of the Warrants will equal the fair market value of such Warrants; (c) the
aggregate basis of the CBC Common received by each holder of KRES Common will be
the same as the aggregate basis of the KRES Common surrendered in exchange
therefor decreased by the fair market value of any Warrants received and
increased by the amount of gain such holder recognizes upon receipt of the
Warrants; and (d) the holding period for the Warrants received in exchange for
KRES Common will commence on the day following receipt of such Warrants.
