                            -----------------------

                                                                    May 20, 1998

MERRILL LYNCH & CO.

        Incorporated

Ladies and Gentlemen:

     CB Richard Ellis Services, Inc., a Delaware corporation (the "Company"),
proposes to issue and sell up to $175,000,000 aggregate principal amount of
senior subordinated debt securities (the "Debt Securities") as described in more
detail in the attached Terms Agreement (as defined below).

     The Debt Securities will be issued under an indenture as supplemented by
the First Supplemental Indenture (the "Indenture") between the Company and a
trustee to be named therein (the "Trustee").

     Whenever the Company determines to make an offering of Debt Securities
pursuant to the attached Terms Agreement through Merrill Lynch & Co., Merrill
Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), or through an
underwriting syndicate managed by Merrill Lynch, the Company will enter into the
attached Terms Agreement (the "Terms Agreement") providing for the sale of such
Debt Securities to, and the purchase and offering thereof by, Merrill Lynch and
such other underwriters, set forth in such Terms Agreement (the "Underwriters,"
which 
<PAGE>
 
term shall include any Underwriter substituted pursuant to Section 10 hereof).
The Terms Agreement shall specify the aggregate principal amount of Debt
Securities to be issued, the name of each Underwriter participating in such
offering (subject to substitution as provided in Section 10 hereof) and the name
of any Underwriter other than Merrill Lynch acting as co-manager in connection
with such offering, the aggregate principal amount, of Debt Securities which
each such Underwriter severally agrees to purchase, whether such offering is on
a fixed or variable price basis and, if on a fixed price basis, the initial
offering price, the price at which the Debt Securities are to be purchased by
the Underwriters, the form, time, date and place of delivery and payment of the
Debt Securities and any other material variable terms of the Debt Securities.
The Terms Agreement, which shall be substantially in the form of Exhibit A
hereto, may take the form of an exchange of any standard form of written
telecommunication between the Company and Merrill Lynch acting as representative
of any other Underwriters.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-48875) for the
registration of among other securities the Debt Securities under the Securities
Act of 1933, as amended (the "1933 Act"), and the offering thereof from time to
time in accordance with Rule 415 of the rules and regulations of the Commission
under the 1933 Act (the "1933 Act Regulations"), and the Company has filed such
post-effective amendments thereto as may be required prior to the execution of
the Terms Agreement.  Such registration statement (as so amended, if applicable)
has been declared effective by the Commission and the Indenture has been duly
qualified under the Trust Indenture Act of 1939, as amended (the "1939 Act").
Such registration statement (as so amended, if applicable), including the
information, if any, deemed to be a part thereof pursuant to Rule 430A(b) of the
1933 Act Regulations (the "Rule 430A Information") or Rule 434(d) of the 1933
Act Regulations (the "Rule 434 Information"), is referred to herein as the
"Registration Statement"; and the final prospectus and the final prospectus
supplement relating to the offering of the Debt Securities, in the form first
furnished to the Underwriters by the Company for use in connection with the
offering of the Debt Securities, are collectively referred to herein as the
"Prospectus"; provided, however, that all references to the "Registration
theStatement" and the "Prospectus" shall also be deemed to include all documents
incorporated therein by reference pursuant to the Securities Exchange Act of
1934, as amended (the "1934 Act"), prior to the execution of the Terms
Agreement; provided, further, that if the Company files a registration statement
with the Commission pursuant to Rule 462(b) of the 1933 Act Regulations (the
"Rule 462 Registration Statement"), then, after such filing, all references to
"Registration Statement" shall also be deemed to include the Rule 462
Registration Statement; and 

                                      -2-
<PAGE>
 
provided, further, that if the Company elects to rely upon Rule 434 of the 1933
Act Regulations, then all references to "Prospectus" shall also be deemed to
include the final or preliminary prospectus and the applicable term sheet or
abbreviated term sheet (the "Term Sheet"), as the case may be, in the form first
furnished to the Underwriters by the Company in reliance upon Rule 434 of the
1933 Act Regulations, and all references in this Underwriting Agreement to the
date of the Prospectus shall mean the date of the Term Sheet. A "preliminary
prospectus" shall be deemed to refer to any prospectus used before the
registration statement became effective and any prospectus that omitted, as
applicable, the Rule 430A Information, the Rule 434 Information or other
information to be included upon pricing in a form of prospectus filed with the
Commission pursuant to Rule 424(b) of the 1933 Act Regulations, that was used
after such effectiveness and prior to the execution and delivery of the Terms
Agreement. For purposes of this Underwriting Agreement, all references to the
Registration Statement, Prospectus, Term Sheet or preliminary prospectus or to
any amendment or supplement to any of the foregoing shall be deemed to include

to make the statements therein, in the light of the circumstances under which

Underwriter as to the matters covered thereby on the date of such certificate.

 2.  Sale and Delivery to Underwriters; Closing.
     ------------------------------------------ 

     a.   Debt Securities.  The several commitments of the Underwriters to
purchase the Debt Securities pursuant to the Terms Agreement shall be deemed to
have been made on the basis of the representations and warranties herein
contained and shall be subject to the terms and conditions herein set forth.

     b.   Payment.  Payment of the purchase price for, and delivery of, the Debt
Securities shall be made at the offices of Pillsbury Madison & Sutro LLP, New
York, New York, or at such other place as shall be agreed upon by Merrill Lynch
and the Company, at  7:00 A.M. (California time) on the third (fourth, if the
pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day
after the date of the Terms Agreement (unless postponed in accordance with the
provisions of Section 10 hereof), or such other time not later than ten business
days after such date as shall be agreed upon by Merrill Lynch and the Company
(such time and date of payment and delivery being herein called "Closing Time").

     Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery to
Merrill Lynch for the respective accounts of the Underwriters of the Debt
Securities to be purchased by them.  It is understood that each Underwriter has
authorized Merrill Lynch, for its account, to accept delivery of, receipt for,
and make payment of the purchase price for, the Debt Securities which it has
severally agreed to purchase.  Merrill Lynch, individually and not as
representative of the Underwriters, may (but shall not be obligated to) make
payment of the purchase price for the Debt Securities to be purchased by any
Underwriter whose funds have not been received by the Closing Time, but such
payment shall not relieve such Underwriter from its obligations hereunder.

     c.   Denominations; Registration.  The Debt Securities or certificates for
the Debt Securities shall be in such denominations and registered in such names
as 

                                     -13-
<PAGE>
 
Merrill Lynch may request in writing at least one full business day prior to
the Closing Time.  The Debt Securities or certificates for the Debt Securities
will be made available for examination and packaging by Merrill Lynch in The
City of New York not later than 10:00 A.M. (Eastern time) on the business day
prior to the Closing Time.

  3.   Covenants of the Company.  The Company covenants with Merrill Lynch and
       ------------------------                                               
with each Underwriter participating in the offering of the Debt Securities, as
follows:

     a.   Compliance with Securities Regulations and Commission Requests. The
Company, subject to Section 3(b), will comply with the requirements of Rule 430A
of the 1933 Act Regulations and/or Rule 434 of the 1933 Act Regulations, if and
as applicable, and will notify Merrill Lynch immediately, and confirm the notice
in writing, of (i) the effectiveness of any post effective amendment to the
Registration Statement or the filing of any supplement or amendment to the
Prospectus, (ii) the receipt of any comments from the Commission, (iii) any
request by the Commission for any amendment to the Registration Statement or any
amendment or supplement to the Prospectus or for additional information, and
(iv) the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus, or of the suspension of the
qualification of the Debt Securities for offering or sale in any jurisdiction,
or of the initiation or threatening of any proceedings for any of such purposes.
The Company will promptly effect the filings necessary pursuant to Rule 424 and
will take such steps as it deems necessary to ascertain promptly whether the
Prospectus transmitted for filing under Rule 424 was received for filing by the
Commission and, in the event that it was not, it will promptly file the
Prospectus.  The Company will make every reasonable effort to prevent the
issuance of any stop order and, if any stop order is issued, to obtain the
lifting thereof at the earliest possible moment.

     b.   Filing of Amendments.  The Company will give Merrill Lynch notice of
its intention to file or prepare any amendment to the Registration Statement
(including any filing under Rule 462(b) of the 1933 Act Regulations), any Term
Sheet or any amendment, supplement or revision to either the prospectus included
in the Registration Statement at the time it became effective or to the
Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will
furnish Merrill Lynch with copies of any such documents a reasonable amount of
time prior to such proposed filing or use, as the case may be, and, in
connection with the issuance of 

                                     -14-
<PAGE>
 
the Debt Securities, will not file or use any such document to which Merrill
Lynch or counsel for the Underwriters shall object.

     c.   Delivery of Registration Statements.  The Company has furnished or
will deliver to Merrill Lynch and counsel for the Underwriters, without charge,
signed copies of the Registration Statement as originally filed and of each
amendment thereto (including exhibits filed therewith or incorporated by
reference therein and documents incorporated or deemed to be incorporated by
reference therein) and conformed copies of all consents and certificates of
experts, and will also deliver to Merrill Lynch, without charge, a conformed
copy of the Registration Statement as originally filed and of each amendment
thereto (without exhibits) for each of the Underwriters.  Copies of the
Registration Statement and each amendment thereto furnished to the Underwriters
will be identical to any electronically transmitted copies thereof filed with
the Commission pursuant to EDGAR, except to the extent permitted by Regulation
S-T.

     d.   Delivery of Prospectuses.  The Company will deliver to each
Underwriter, without charge, as many copies of each preliminary prospectus as
such Underwriter may reasonably request, and the Company hereby consents to the
use of such copies for purposes permitted by the 1933 Act.  The Company will
furnish to each Underwriter, without charge, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such
number of copies of the Prospectus as such Underwriter may reasonably request.
The Prospectus and any amendments or supplements thereto furnished to the
Underwriters will be identical to any electronically transmitted copies thereof
filed with the Commission pursuant to EDGAR, except to the extent permitted by
Regulation S-T.

     e.   Continued Compliance with Securities Laws.  The Company will comply
with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act
Regulations so as to permit the completion of the distribution of the Debt
Securities as contemplated in this Underwriting Agreement and the Terms
Agreement and in the Registration Statement and the Prospectus.  If at any time
when the Prospectus is required by the 1933 Act or the 1934 Act to be delivered
in connection with sales of the Debt Securities, any event shall occur or
condition shall exist as a result of which it is necessary, in the opinion of
counsel for the Underwriters or for the Company, to amend the Registration
Statement in order that the Registration Statement will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading or to
amend or supplement the Prospectus in order that the Prospectus will not include
an untrue statement of a material fact or omit to state a material fact



                                     -15-
<PAGE>
 
necessary in order to make the statements therein not misleading in the light of
the circumstances existing at the time it is delivered to a purchaser, or if it
shall be necessary, in the opinion of such counsel, at any such time to amend
the Registration Statement or amend or supplement the Prospectus in order to
comply with the requirements of the 1933 Act or the 1933 Act Regulations, the
Company will promptly prepare and file with the Commission, subject to Section
3(b), such amendment or supplement as may be necessary to correct such statement
or omission or to make the Registration Statement or the Prospectus comply with
such requirements, and the Company will furnish to the Underwriters, without
charge, such number of copies of such amendment or supplement as the
Underwriters may reasonably request.

     f.   Blue Sky Qualifications.  The Company will use its best efforts, in
cooperation with the Underwriters, to qualify the Debt Securities for offering
and sale under the applicable securities laws of such states and other
jurisdictions (domestic or foreign) as Merrill Lynch may designate and to
maintain such qualifications in effect for a period of not less than one year
from the date of the Terms Agreement; provided, however, that the Company shall
not be obligated to file any general consent to service of process or to qualify
as a foreign corporation or as a dealer in securities in any jurisdiction in
which it is not so qualified or to subject itself to taxation in respect of
doing business in any jurisdiction in which it is not otherwise so subject.  In
each jurisdiction in which the Debt Securities have been so qualified, the
Company will file such statements and reports as may be required by the laws of
such jurisdiction to continue such qualification in effect for a period of not
less than one year from the date of the Terms Agreement.

     g.   Earnings Statement.  The Company will timely file such reports
pursuant to the 1934 Act as are necessary in order to make generally available
to its securityholders as soon as practicable an earnings statement for the
purposes of, and to provide the benefits contemplated by, the last paragraph of
Section 11(a) of the 1933 Act.

     h.   Use of Proceeds.  The Company will use the net proceeds received by it
from the sale of the Debt Securities in the manner specified in the Prospectus
under "Use of Proceeds."

     i.   Restriction on Sale of Securities.  Between the date of the Terms
Agreement and the Closing Time or such other date specified in such Terms
Agreement, the Company will not, without the prior written consent of Merrill
Lynch, 

                                     -16-
<PAGE>
 
directly or indirectly, issue, sell, offer to sell, grant any option for the
sale of, or otherwise dispose of, the securities specified in the Terms
Agreement.

     j.   Reporting Requirements.  The Company, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will
file all documents required to be filed with the Commission pursuant to the 1934
Act within the time periods required by the 1934 Act and the 1934 Act
Regulations.

 4.  Payment of Expenses.

amendment thereto, (vi) the printing and delivery to the Underwriters of copies
of each preliminary prospectus, any Term Sheet, and the Prospectus and any

recognized statistical rating organizations for the rating of the Debt
Securities, (viii) the filing fees incident to, and the reasonable fees and
disbursements of counsel to the Underwriters in connection with, the review, if
any, by the National Association of Securities Dealers, Inc. (the "NASD") of the

Underwriter acting in the capacity of a "qualified independent underwriter" (as

Merrill Lynch in accordance with the provisions of Section 5 (except for Section

Underwriters for all of their out-of-pocket expenses, including the reasonable
fees and disbursements of counsel for the Underwriters.

  5. Conditions of Underwriters' Obligations.  The obligations of the
     ---------------------------------------                         
Underwriters to purchase and pay for the Debt Securities pursuant to the Terms
Agreement are subject to the accuracy of the representations and warranties of
the Company contained in Section 1 hereof or in certificates of any officer of
the Company or any of its subsidiaries delivered pursuant to the provisions

including any Rule 462(b) Registration Statement, has become effective under the
1933 Act and no stop order suspending the effectiveness of the Registration

purpose shall have been initiated or be pending or threatened by the Commission,
and any request on the part of the Commission for additional information shall
have been complied with to the reasonable satisfaction of counsel to the
Underwriters.  A prospectus containing information relating to the description

Arps, Slate, Meagher & Flom, LLP, counsel for the Underwriters, together with
signed or reproduced copies of such letter for each of the other Underwriters,
with respect to the matters set forth in (i), (ii), (iv), (v), (vi), (vii),
(viii), (ix) and (xiv) (solely as to the information in the Prospectus under

and of the chief financial officer or chief accounting officer of each of the
Company and CB Richard Ellis, dated as of Closing Time, to the effect that (i)
there has been no such material adverse change, (ii) the representations and
warranties in Section 1 are true and correct with the same force and effect as

accorded by any "nationally recognized statistical rating organization," as

Regulations, if and as specified in the Terms Agreement, and the Company shall
have delivered to Merrill Lynch a letter, dated as of such date, from each such
rating organization, or other evidence satisfactory to Merrill Lynch, confirming
that the Debt Securities have such ratings.  Since the time of execution of the
Terms Agreement, there shall not have occurred a downgrading in the rating
assigned to the Debt Securities or any of the Company's other securities by any
such rating organization, and no such rating organization shall have publicly

Company in connection with the issuance and sale of the Debt Securities as

and counsel for the Underwriters.

     l.   Termination of Terms Agreement.  In addition to the termination
provisions provided in Section 9 hereof, if any condition specified in this
Section 5 shall not have been fulfilled when and as required to be fulfilled,
the Terms Agreement may be terminated by Merrill Lynch by notice to the Company
at any time at or prior to the Closing Time, and such termination shall be
without liability of any party to any other party except as provided in Section

 6.  Indemnification.
     --------------- 

     a.   Indemnification of Underwriters.  Subject to Section 6(c) below, the
Company and CB Richard Ellis jointly and severally agree to indemnify and hold
harmless each Underwriter and each person, if any, who controls any Underwriter
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 as
follows:

          i.   against any and all loss, liability, claim, damage and expense
whatsoever, as incurred, arising out of any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement (or any
amendment thereto), including the Rule 430A Information and the Rule 434
Information deemed to be a part thereof, if applicable, or the omission or
alleged omission therefrom of a material fact required to be stated therein or
necessary to make the statements therein not misleading or arising out of any
untrue statement or alleged untrue statement of a material fact included in any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or the omission or alleged omission therefrom of a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading;



                                     -21-
<PAGE>
 
          ii.  against any and all loss, liability, claim, damage and expense
whatsoever, as incurred, to the extent of the aggregate amount paid in
settlement of any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or of any claim whatsoever
based upon any such untrue statement or omission, or any such alleged untrue
statement or omission; provided that (subject to Section 6(d) below) any such
settlement is effected with the written consent of the Company; and

          iii. against any and all expense whatsoever, as incurred (including
the reasonable fees and disbursements of counsel chosen by Merrill Lynch), in
investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue statement or
omission, or any such alleged untrue statement or omission, to the extent that
any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
- --------  -------                                                            
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through Merrill Lynch expressly for use in the Registration
Statement (or any amendment thereto), including the Rule 430A Information and
the Rule 434 Information deemed to be a part thereof, if applicable, or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto). In addition, neither the Company nor CB Richard Ellis will be liable
to any Underwriter with respect to any Preliminary Prospectus to the extent that
any such loss, liability, claim, damage or expense resulted from the fact that
such Underwriter, in contravention of a requirement of this Agreement or
applicable law, sold Debt Securities to a person to whom such Underwriter failed
to send or give, at or prior to the Closing Time, a copy of the Prospectus, as
then amended or supplemented, if the Company has previously furnished copies
thereof (sufficiently in advance of the Closing Time to allow for distribution
by the Closing Time) to the Underwriter and the loss, liability, claim, damage
or expense of such Underwriter resulted from an untrue statement or omission of
a material fact contained in or omitted from the Preliminary Prospectus which
was corrected in the Prospectus as, if applicable, amended or supplemented prior
to the Closing Time and such Prospectus was required by law to be delivered at
or prior to the written confirmation of sale to such person.



                                     -22-
<PAGE>
 
     b.   Indemnification of Company, Directors and Officers.  Each Underwriter
severally agrees to indemnify and hold harmless the Company, its directors, each
of its officers who signed the Registration Statement, and each person, if any,
who controls the Company within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act against any and all loss, liability, claim, damage
and expense described in the indemnity contained in subsection (a) of this
Section, as incurred, but only with respect to untrue statements or omissions,
or alleged untrue statements or omissions, made in the Registration Statement
(or any amendment thereto), including the Rule 430A Information and the Rule 434
Information deemed to be a part thereof, if applicable, or any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Company by such Underwriter through Merrill Lynch expressly for use in the
Registration Statement (or any amendment thereto) or such preliminary prospectus
or the Prospectus (or any amendment or supplement thereto).

     c.   Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  Except as set forth below, in the case of parties indemnified
pursuant to Section 6(a) above, counsel to the indemnified parties shall be
selected by Merrill Lynch, and, in the case of parties indemnified pursuant to
Section 6(b) above, counsel to the indemnified parties shall be selected by the
Company.  An indemnifying party may participate at its own expense in the
defense of any such action.  If any indemnifying party so elects to participate
in the defense of such action within a reasonable time after receipt of notice
of an action commenced against an indemnified party, an indemnifying party,
jointly with any other indemnifying parties receiving such notice, may assume
the defense of such action with counsel chosen by it and approved by the
indemnified 


                                     -23-
<PAGE>
 
parties defendant in such action, unless such indemnified parties reasonably
object to such assumption on the ground that there may be legal defenses
available to them which are different from or in addition to those available to
such indemnifying party. If an indemnifying party assumes the defense of such
action, the indemnifying parties shall not be liable for any fees and expenses
of counsel for the indemnified parties incurred thereafter in connection with
such action. In no event shall the indemnifying parties be liable for fees and
expenses of more than one counsel (in addition to any local counsel) separate
from their own counsel for all indemnified parties in connection with any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances. No indemnifying
party shall, without the prior written consent of the indemnified parties,
settle or compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.

     d.   Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.  Notwithstanding the immediately preceding sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, an indemnifying party shall
not be liable for any settlement of the nature contemplated by Section 6(a)(ii)
effected without its consent if such indemnifying party (i) reimburses such
indemnified party in accordance with such request to the extent it considers
such request to be reasonable and (ii) provides written notice to the
indemnified party substantiating the unpaid balance as unreasonable, in each
case prior to the date of such settlement.

  7. Contribution.  If the indemnification provided for in Section 6 hereof is
     ------------                                                             
for any reason unavailable to or insufficient to hold harmless an indemnified
party in respect of any losses, liabilities, claims, damages or expenses
referred to therein, then each indemnifying party shall contribute to the
aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and CB
Richard Ellis, on the one hand, and the Underwriters, on the other hand, from
the offering of the Debt Securities pursuant to the Terms 

                                     -24-
<PAGE>
 
Agreement or (ii) if the allocation provided by clause (i) is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and CB Richard Ellis, on the one hand, and of the Underwriters, on
the other hand, in connection with the statements or omissions which resulted in
such losses, liabilities, claims, damages or expenses, as well as any other
relevant equitable considerations.

     The relative benefits received by the Company and CB Richard Ellis, on the
one hand, and the Underwriters, on the other hand, in connection with the
offering of the Debt Securities pursuant to the Terms Agreement shall be deemed
to be in the same respective proportions as the total net proceeds from the
offering of such Debt Securities (before deducting expenses) received by the
Company and the total underwriting discount received by the Underwriters, in
each case as set forth on the cover of the Prospectus, or, if Rule 434 is used,
the corresponding location on the Term Sheet bear to the aggregate initial
public offering price of such Debt Securities as set forth on such cover.

     The relative fault of the Company and CB Richard Ellis, on the one hand,
and the Underwriters, on the other hand, shall be determined by reference to,
among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company and CB Richard Ellis or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     The Company and CB Richard Ellis and the Underwriters agree that it would
not be just and equitable if contribution pursuant to this Section 7 were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
7.  The aggregate amount of losses, liabilities, claims, damages and expenses
incurred by an indemnified party and referred to above in this Section 7 shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified parry in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 7, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at 



                                     -25-
<PAGE>
 
which the Debt Securities underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of any such untrue or alleged
untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company who signed the
Registration Statement, and each person, if any, who controls the Company within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have the same rights to contribution as the Company.  The Underwriters'
respective obligations to contribute pursuant to this Section 7 are several in
proportion to the aggregate principal amount, of Debt Securities set forth
opposite their respective names in the Terms Agreement, and not joint.

  8. Representations, Warranties and Agreements to Survive Delivery.   All
     --------------------------------------------------------------       
representations, warranties and agreements contained in this Underwriting
Agreement and the Terms Agreement or in certificates of officers of the Company
submitted pursuant hereto or thereto shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of any
Underwriter or controlling person, or by or on behalf of the Company, and shall
survive delivery of and payment for the Debt Securities.

 9.  Termination
     -----------

     a.   Underwriting Agreement.  This Underwriting Agreement (excluding the
Terms Agreement) may be terminated for any reason at any time by the Company or
by Merrill Lynch upon the giving of 30 days' prior written notice of such
termination to the other party hereto.

     b.   Terms Agreement.  Merrill Lynch may terminate the Terms Agreement, by
notice to the Company, at any time at or prior to the Closing Time, if (i) there
has been, since the time of execution of the Terms Agreement or since the
respective dates as of which information is given in the Prospectus, any
material adverse change in the condition, financial or otherwise, or in the
earnings, business 



                                     -26-
<PAGE>
 
affairs or business prospects of the Company and its subsidiaries considered as
one enterprise, whether or not arising in the ordinary course of business, or
(ii) there has occurred any material adverse change in the financial markets in
the United States, or any outbreak of hostilities or escalation thereof or other
calamity or crisis or any change or development involving a prospective change
in national or international political, financial or economic conditions, in
each case the effect of which is such as to make it, in the judgment of Merrill
Lynch, impracticable to market the Debt Securities or to enforce contracts for
the sale of the Debt Securities, or (iii) trading in any securities of the
Company has been suspended or materially limited by the Commission or the New
York Stock Exchange or if trading generally on the New York Stock Exchange or
the American Stock Exchange or in the Nasdaq National Market has been suspended
or limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices have been required, by either of said exchanges or by such
system or by order of the Commission, the NASD or any other governmental
authority, or (iv) a banking moratorium has been declared by either Federal or
New York authorities.

     c.   Liabilities.  If this Underwriting Agreement or the Terms Agreement is
terminated pursuant to this Section 9, such termination shall be without
liability of any party to any other party except as provided in Section 4
hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such
termination and remain in full force and effect.

  10.  Default by One or More of the Underwriters.  If one or more of the
       ------------------------------------------                        
Underwriters shall fail at the Closing Time, to purchase the Debt Securities
which it or they are obligated to purchase under the Terms Agreement (the
"Defaulted Securities"), then Merrill Lynch shall have the right, within 24
hours thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, Merrill Lynch shall not have completed such
arrangements within such 24-hour period, then:

     a.   if the number or aggregate principal amount, as the case may be, of
Defaulted Securities does not exceed 10% of the aggregate principal amount, of
Debt Securities to be purchased on such date pursuant to the Terms Agreement,
the non-defaulting Underwriters shall be obligated, severally and not jointly,
to purchase the full amount thereof in the proportions that their respective
underwriting obligations under the Terms Agreement bear to the underwriting
obligations of all non-defaulting Underwriters, or



                                     -27-
<PAGE>
 
     b.   if the aggregate principal amount of Defaulted Securities exceeds 10%
of the aggregate principal amount of Debt Securities to be purchased on such
date pursuant to the Terms Agreement, the Terms Agreement shall terminate
without liability on the part of any non-defaulting Underwriter.

     No action taken pursuant to this Section 10 shall relieve any defaulting
Underwriter from liability in respect of its default.

     In the event of any such default which does not result in a termination of
the Terms Agreement, either Merrill Lynch or the Company shall have the right to
postpone the Closing Time, for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or the Prospectus or
in any other documents or arrangements.

  11.  Notices.  All notices and other communications hereunder shall be in

                            Independent Underwriter
                            -----------------------

     The Company hereby confirms its engagement of Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("Merrill Lynch") as, and Merrill Lynch hereby confirms its
agreement with the Company to render services as, a "qualified independent
underwriter" within the meaning of Rule 2720 of the Conduct Rules of the
National Association of Securities Dealers, Inc. (the "NASD Conduct Rules") with
respect to the offering and sale of the Debt Securities.  Merrill Lynch, solely
in its capacity as qualified independent underwriter and not otherwise, is
referred to herein as the "Independent Underwriter."

     In addition to and without limitation of the obligations of the Company and
CB Richard Ellis, Inc., a Delaware corporation and a wholly owned subsidiary of
the Company ("CB Richard Ellis"), to indemnify Merrill Lynch as an Underwriter,
the Company and CB Richard Ellis also agree to indemnify and hold harmless the
Independent Underwriter and each person, if any, who controls the Independent
Underwriter within the meaning of Section 15 of the Securities Act of 1933 (the
"1933 Act"), as amended or Section 20 of the Exchange Act of 1934 (the "1934
Act"), as amended, from and against any and all loss, liability, claim, damage
and expense whatsoever, as incurred, incurred as a result of the Independent
Underwriter's participation as a "qualified independent underwriter" within the
meaning of Rule 2720 of the NASD Conduct Rules in connection with the offering
of the Underwritten Securities.  If indemnity is sought pursuant to this
paragraph, the Company and CB Richard Ellis shall be liable for the reasonable
fees and expenses of not more than one counsel (in addition to any local
counsel) separate from their own counsel and that of other parties entitled to
indemnification under the Underwriting Agreement, dated the date hereof, among
the Company, CB Richard Ellis and Merrill Lynch, for the Independent Underwriter
in its capacity as a "qualified independent underwriter" and all persons, if
any, who control the Independent Underwriter within the meaning of Section 15 of
the 1933 Act or Section 20 of 1934 Act in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances if, in the reasonable judgment of
the Independent Underwriter, there may exist a conflict of interest between the
Independent Underwriter and the other indemnified parties.  Any such separate
counsel for the Independent Underwriter and such control persons of the
Independent Underwriter shall be designated in writing by the Independent
Underwriter.

     The Company, CB Richard Ellis and the Underwriters agree that Merrill Lynch
will not receive any additional benefits hereunder for serving as the
Independ-

                      FORM OF OPINION OF COMPANY'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                  SECTION 5(b)


          i.   The Company has been duly incorporated and is validly existing as
a corporation in good standing under the laws of the State of Delaware.

          ii.  The Company has corporate power and authority to own, lease and
operate its properties and to conduct its business as described in the
Prospectus and to enter into and perform its obligations under the Underwriting
Agreement and the Terms Agreement.

          iii. The Company is duly qualified as a foreign corporation to
transact business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure so to qualify or
to be in good standing would not result in a Material Adverse Effect.

          iv.  Each of the Underwriting Agreement and the Terms Agreement has
been duly authorized, executed and delivered by the Company and CB Richard
Ellis, as applicable.

          v.   The Debt Securities have been duly authorized by the Company for
issuance and sale pursuant to the Underwriting Agreement.  The Debt Securities,
when issued and authenticated in the manner provided for in the Indenture and
delivered against payment of the consideration therefor specified in the
Underwriting Agreement and the Terms Agreement, will constitute valid and
legally binding obligations of the Company, enforceable against the Company in
accordance with their terms and the terms of the Indenture, except as the
enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting creditors' rights
generally or by general equitable principles.  The Debt Securities are in the
form contemplated by, and each registered holder thereof is entitled to the
benefits of, the Indenture.

          vi.  The Indenture has been duly authorized, executed and delivered by
the Company.

                                      B-1
<PAGE>
 
          vii.  The Debt Securities being sold pursuant to the Underwriting
Agreement, Terms Agreement and the Indenture conform in all material respects to
the statements relating thereto contained in the Prospectus and are in
substantially the form filed or incorporated by reference, as the case may be,
as an exhibit to the Registration Statement.

          viii. The Registration Statement, including any Rule 462(b)
Registration Statement, has been declared effective under the 1933 Act; any
required filing of the Prospectus pursuant to Rule 424(b) has been made in the
manner and within the time period required by Rule 424(b); and, to the best of
our knowledge, no stop order suspending the effectiveness of the Registration
Statement or any Rule 462(b) Registration Statement has been issued under the
1933 Act and, to the best of our knowledge, no proceedings for that purpose have
been instituted or are pending or threatened by the Commission.

          ix.   The Registration Statement, including any Rule 462(b)
Registration Statement, the Rule 430A Information and the Rule 434 Information,
as applicable, the Prospectus and each amendment or supplement to the
Registration Statement and Prospectus, excluding the documents incorporated by
reference therein, as of their respective effective or issue dates (other than
the financial statements and notes thereto, other financial information and
supporting schedules included therein or omitted therefrom and the Trustee's
Statement of Eligibility on Form T-1 (the "Form T-1"), as to which we need
express no opinion) complied as to form in all material respects with the
requirements of the 1933 Act and the 1933 Act Regulations; provided, however
that in passing upon the compliance as to form of the Registration Statement and
the Prospectus, we have assumed that the statements therein are correct and
complete.

          x.    The documents incorporated by reference in the Prospectus (other
than the financial statements and notes thereto and supporting schedules therein
or omitted therefrom, as to which we express no opinion), when they became
effective or were filed with the Commission, as the case may be, complied as to
form in all material respects with the requirements of the 1933 Act or the 1934
Act, as applicable, and the rules and regulations of the Commission thereunder.

          xi.   The Debt Securities, upon issuance, will be excluded or exempted
under, or beyond the purview of, the Commodity Exchange Act, as amended (the
"Commodity Exchange Act"), and the rules and regulations of the 

                                      B-2
<PAGE>
 
Commodity Futures Trading Commission under the Commodity Exchange Act (the
"Commodity Exchange Act Regulations").

          xii.  If Rule 434 has been relied upon, the Prospectus was not
"materially different," as such term is used in Rule 434, from the prospectus
included in the Registration Statement at the time it became effective.

          xiii. To the best of our knowledge, except as disclosed in the
Prospectus, there is not pending or threatened any action, suit, proceeding,
inquiry or investigation, to which the Company or any subsidiary is a party, or
to which the property of the Company or any subsidiary is subject, before or
brought by any court or governmental agency or body, domestic or foreign, which
might reasonably be expected to result in a Material Adverse Effect, or which
might reasonably be expected to materially and adversely affect the consummation
of the transactions contemplated by the Underwriting Agreement or the
performance by the Company of its obligations under the Underwriting Agreement.

          xiv.  The information in the Prospectus under "Description of the
Notes" and "Description of Certain Other Indebtedness" and in the Registration
Statement under Item 15, to the extent that it constitutes matters of law,
summaries of legal matters, summaries of the Company's charter and by-laws or
legal conclusions, has been reviewed by us and is correct in all material
respects.

          xv.   To the best of our knowledge, there are no California, New York
or federal statutes or regulations that are required to be described in the
Prospectus that are not described or incorporated therein as required.

          xvi.  All descriptions in the Registration Statement of material
contracts and other documents which are described individually to which the
Company or its Subsidiaries are a party are accurate in all material respects;
to the best of our knowledge, there are no franchises, contracts, indentures,
mortgages, loan agreements, notes, leases or other instruments required to be
described in the Registration Statement or to be filed as exhibits thereto other
than those described therein or filed or incorporated by reference as exhibits
thereto, and the descriptions thereof are correct in all material respects.

          xvii. To the best of our knowledge, neither the Company nor any
Subsidiary is in violation of its charter or by-laws and no default by the
Company or any Subsidiary exists in the due performance or observance of any
material obligation, agreement, covenant or condition contained in any contract,
indenture, mort-


                                      B-3
<PAGE>
 
gage, loan agreement, note, lease or other agreement or instrument that is
individually described in the Registration Statement or the Prospectus or filed
or incorporated by reference and currently in effect as an exhibit to the
Registration Statement, except for such violations or defaults that would not
reasonably be expected to have a Material Adverse Effect.

          xvii. To the best of our knowledge, no filing with, or authorization,
approval, consent, license, order, registration, qualification or decree of, any
court or governmental authority or agency, (other than under the 1933 Act and
the 1933 Act Regulations and the 1939 Act, which have been obtained, or as may
be required under the securities or blue sky laws of the various states, as to
which we need express no opinion) is necessary or required in connection with
the due authorization, execution and delivery of the Underwriting Agreement and
the Terms Agreement or for the offering, issuance or sale of the Debt
Securities.

          xix.  The execution, delivery and performance of the Underwriting
Agreement, the Terms Agreement and the Indenture and the consummation of the
transactions contemplated in the Underwriting Agreement, the Terms Agreement,
the Indenture and in the Registration Statement (including the issuance and sale
of the Debt Securities and the use of the proceeds from the sale of the Debt
Securities as described in the Prospectus under the caption "Use Of Proceeds")
and compliance by the Company with its obligations under the Underwriting
Agreement and the Terms Agreement do not and will not, whether with or without
the giving of notice or lapse of time or both, conflict with or constitute a
breach of, or default or Repayment Event under or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Company or any Subsidiary pursuant to any material contract, indenture,
mortgage, deed of trust, loan or credit agreement, note, lease or any other
agreement or instrument, known to us, to which the Company or any Subsidiary is
a party or by which it or any of them may be bound, or to which any of the
property or assets of the Company or any Subsidiary is subject (except for such
conflicts, breaches or defaults, Repayment Events or liens, charges or
encumbrances that would not have a Material Adverse Effect), except that (i)
borrowings under the Company's credit agreements are guaranteed by CB Richard
Ellis, (ii) all the capital stock of CB Richard Ellis is pledged to secure the
guarantee, and (iii) substantially all assets of the Company and its
subsidiaries are pledged to its lenders under the credit agreements as described
in the Prospectus; nor will any such action result in any violation of the
provisions of the charter or by-laws of the Company or any Subsidiary, or any
applicable law, statute, rule, regulation, judgment, order, writ or decree,
known to us, of any state or U.S. federal government, government instrumentality
or court (other than ordinances and regulations of 


                                      B-4
<PAGE>
 
counties and political subdivisions thereof), having jurisdiction over the
Company or any Subsidiary or any of their respective properties, assets or
operations which, in our experience, is normally applicable to transactions of
the type contemplated by the Underwriting Agreement and the Terms Agreement
(except state securities laws as to which we need to express no opinion).

          xx.  To the best of our knowledge, except as described in the
Prospectus, there are no persons with rights to have any securities registered
pursuant to the Registration Statement or otherwise registered by the Company
under the 1933 Act.

          xxi. The Company is not an "investment company" or an entity
"controlled" by an "investment company," as such terms are defined in the 1940
Act.

     Nothing has come to our attention that would lead us to believe that the
Registration Statement or any amendment thereto, including the Rule 430A
Information and Rule 434 Information (if applicable), (except for financial
statements, including the notes thereto, and related schedules and other
financial and accounting data included therein or omitted therefrom, as to which
we need make no statement), at the time such Registration Statement or any such
amendment became effective, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus or any
amendment or supplement thereto (except for financial statements, including the
notes thereto, and related schedules and other financial and accounting data
included therein or omitted therefrom, as to which we need make no statement),
at the time the Prospectus was issued, at the time any such amended or
supplemented prospectus was issued or at the Closing Time, included or includes
an untrue statement of a material fact or omitted or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates of
responsible officers of the Company and public officials.  Such opinion shall
not state that it is to be governed or qualified by, or that it is otherwise
subject to, any treatise, written policy or other document relating to legal
opinions, including, without limitation, the Legal Opinion Accord of the ABA
Section of Business Law (1991).

                  FORM OF OPINION OF COMPANY'S GENERAL COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                  SECTION 5(b)


          i.   Each of CB Richard Ellis, Inc., formerly known as CB Commercial
Real Estate Group, Inc. ("Real Estate Group"), L.J. Melody & Company, and
Westmark Realty Advisors L.L.C. ("Westmark"), and Koll Real Estate Services
(collectively, the "Subsidiaries") has been duly incorporated, or, in the case
of Westmark, duly formed, and is validly existing as a corporation, or, in the
case of Westmark, is validly existing as a limited liability company, in good
standing under the laws of the jurisdiction of its incorporation or, in the case
of Westmark, its jurisdiction of formation, has corporate power and authority to
own, lease and operate its properties and to conduct its business as described
in the Prospectus and is duly qualified as a foreign corporation to transact
business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure so to qualify or
to be in good standing would not result in a Material Adverse Effect; except as
otherwise disclosed in the Registration Statement, all of the issued and
outstanding equity securities of any Subsidiary has been duly authorized and
validly issued, is fully paid and non-assessable and, to the best of my
knowledge, is owned by the Company, directly or through subsidiaries, free and
clear of any security interest, mortgage, pledge, lien, encumbrance, claim or
equity; none of the outstanding equity securities of each Subsidiary was issued
in violation of the preemptive rights of any securityholder of each Subsidiary
arising by operation of law or the subsidiary's charter or bylaws, provided,
however, that all of the outstanding equity securities of the Subsidiaries
(except for Westmark) are pledged to secure outstanding indebtedness of the
Company under the credit agreements as described in the Prospectus.

     Nothing has come to my attention that would lead me to believe that the
Registration Statement or any amendment thereto, including the Rule 430A
Information and Rule 434 Information (if applicable), (except for financial
statements, including the notes thereto, and related schedules and other
financial and accounting data included therein or omitted therefrom, as to which
I need make no statement), at the time such Registration Statement or any such
amendment became effective, contained an untrue statement of a material fact or
omitted to state a material fact 



                                      C-1
<PAGE>
 
required to be stated therein or necessary to make the statements therein not
misleading or that the Prospectus or any amendment or supplement thereto (except
for financial statements, including the notes thereto, and related schedules and
other financial and accounting data included therein or omitted therefrom, as to
which I need make no statement), at the time the Prospectus was issued, at the
time any such amended or supplemented prospectus was issued or at the Closing
Time, included or includes an untrue statement of a material fact or omitted or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

     In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates of
responsible officers of the Company and public officials.  Such opinion shall
not state that it is to be governed or qualified by, or that it is otherwise
subject to, any treatise, written policy or other document relating to legal
opinions, including, without limitation, the Legal Opinion Accord of the ABA
Section of Business Law (1991).

                          CERTIFICATE OF INCORPORATION

                        CB RICHARD ELLIS SERVICES, INC.



       FIRST:  The name of the corporation is:
       -----                                  

               CB Richard Ellis Services, Inc.

       SECOND:  The registered office of the corporation in the State of
       ------                                                           
Delaware is located at 1013 Centre Road, City of Wilmington, County of New
Castle.  The name of the registered agent of the corporation at such address is

       THIRD:  The purpose of the corporation is to engage in any lawful act or
       -----                                                                   
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware as the same exists or may hereafter be amended.

       FOURTH:
       ------ 

     A.  The total number of shares of all classes of capital stock that the
corporation is authorized to issue is 108,000,000, of which 8,000,000 shall be
Preferred Stock ("Preferred Stock") and 100,000,000 shall be Common Stock
("Common Stock").  Both the Preferred Stock and Common Stock shall have a par
value of $.01 per share.

     B.  The Common Stock shall consist of a single class of 100,000,000 shares,
each of which shall be identical.  There shall be no cumulative voting.

     C.  The Preferred Stock shall consist of a single class of 8,000,000 shares
and may be issued from time to time in one or more series.  The Board of
Directors of the corporation (the "Board of Directors") is expressly authorized
to provide for the issue of all or any of the Preferred Stock in one or more
series, to fix the designation and number of shares thereof and to determine or
alter for each such series, such voting powers, full or limited, or no voting
powers, and such designations, preferences and relative, participating,
optional or other special rights, and the qualifications, limitations or
restrictions thereof, as shall be stated and expressed in the resolution or
resolutions adopted by the Board of Directors providing for the issuance of such
stock and as may be permitted by the General Corporation Law of the State of
Delaware.  The Board of Directors is also expressly authorized to increase or
decrease (but not below the number of shares of such series then outstanding,
plus the number of shares of such series issuable upon exercise of outstanding
rights, options or warrants or upon conversion of outstanding securities issued
by the corporation) the number of shares of any series. If the number of shares
of any such series shall be so decreased, the shares constituting such decrease
shall resume the status that they had prior to the adoption of the resolution
originally fixing the number of shares of such series.

       FIFTH:  A director of the corporation shall not be liable to the
       -----                                                           
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except to the extent such exemption from liability or
limitation thereof is not permitted under the General Corporation Law of the
State of 
<PAGE>
 
Delaware as the same exists or may hereafter be amended.  Any repeal or
modification of the foregoing sentence shall not adversely affect any right or
protection of a director of the corporation existing hereunder with respect to
any act or omission occurring prior to such repeal or modification.

       SIXTH:
       ----- 

     A.  The corporation 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 the corporation or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
of a partnership, joint venture, trust, enterprise or nonprofit entity,
including service with respect to employee benefit plans (an "Indemnitee"),
against all liability and loss suffered and expenses (including attorneys' fees)
reasonably incurred by such person.  The corporation shall not be required to
indemnify and hold harmless a person in connection with a Proceeding (or part
thereof) initiated by such person unless the Proceeding (or the part thereof
initiated by such person) was authorized by the Board of Directors.

     B.  The right to indemnification conferred by this Article SIXTH shall be
presumed to have been relied upon by the Indemnitee and shall be enforceable as
a contract right.  The corporation 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
SIXTH or in any such contract.

     C.  Except for any Proceeding described in the last sentence of Section A
of Article SIXTH, upon making a request for indemnification, the Indemnitee
shall be presumed to be entitled to indemnification under this Article SIXTH and
the corporation 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 A of Article SIXTH) consistent with the
provisions of applicable law.

     D.  Any repeal or modification of the foregoing provisions of this Article
SIXTH shall not adversely affect any right or protection of any Indemnitee
existing at the time of such repeal or modification.

       SEVENTH:  The Board of Directors is authorized to adopt, amend or repeal
       -------                                                                 
the By-laws of the corporation, without any action on the part of the
stockholders, solely by the affirmative vote of at least a majority of the
directors of the corporation then in office.

the extent reducing Consolidated Net Income, Consolidated Interest Expense, and
(d) to the extent reducing Consolidated Net Income, Consolidated Income Tax
Expense less (ii) other non-cash items increasing Consolidated Net Income for
such period.

CONSOLIDATED FIXED CHARGE COVERAGE RATIO

     The term "Consolidated Fixed Charge Coverage Ratio" means the ratio of the
aggregate amount of Consolidated Cash Flow Available for Fixed Charges of the
Corporation for the four full fiscal quarters immediately preceding the date of
the transaction (the "Transaction Date") giving rise to the need to calculate
the Consolidated Fixed Charge Coverage Ratio for which consolidated financial
information of the Corporation is available (such four full fiscal quarter
period being referred to herein as the "Four Quarter Period") to the aggregate
amount of Consolidated Fixed Charges of the Corporation for such Four Quarter
Period.  For purposes of this definition, "Consolidated Cash Flow Available for
Fixed Charges" and "Consolidated Fixed Charges" will be calculated, without
duplication, after giving effect on a pro forma basis for the period of such
calculation to (i) the incurrence of any Indebtedness of the Corporation or any
of the Restricted Subsidiaries during the period commencing on the first day of
the Four Quarter Period to and including the Transaction Date (the "Reference
Period"), including, without limitation, the incurrence of the Indebtedness

on the first day of the Reference Period, except that with respect to the
calculation of Consolidated Interest Expense in the determination of
Consolidated Fixed Charges, the Consolidated Interest Expense of such Person
attributable to interest on any Indebtedness under a revolving credit facility

balance of such Indebtedness based upon the number of days that such Facility
was in existence during the Reference Period, (ii) an adjustment to eliminate or

                                      -4-
<PAGE>
 
Consolidated Cash Flow Available for Fixed Charges and Consolidated Fixed
Charges of the Corporation directly attributable to assets which are the subject
of any Asset Sale or Asset Acquisition (including, without limitation, any Asset
Acquisition giving rise to the need to make such calculation as a result of the
Corporation or one of the Restricted Subsidiaries (including any Person who
becomes a Restricted Subsidiary as a result of the Asset Acquisition) incurring
Acquired Indebtedness) occurring during the Reference Period and (iii) the
retirement of Indebtedness during the Reference Period which cannot thereafter
be reborrowed occurring as if retired on the first day of the Reference Period.
In calculating "Consolidated Fixed Charges" for purposes of determining the
denominator (but not the numerator) of this "Consolidated Fixed Charge Coverage
Ratio," (1) interest on Indebtedness determined on a fluctuating basis as of the
Transaction Date and which will continue to be so determined thereafter will be
deemed to accrue at a fixed rate per annum equal to the rate of interest on such
Indebtedness in effect on the Transaction Date; (2) if interest on any
Indebtedness actually incurred on the Transaction Date may optionally be
determined at an interest rate based upon a factor of a prime or similar rate, a
eurocurrency interbank offered rate, or other rates, then the interest rate in
effect on the Transaction Date shall be deemed to have been in effect during the
Reference Period; and (3) notwithstanding clause (1) above, interest on
Indebtedness determined on a fluctuating basis, to the extent such interest is
covered by Interest Rate Agreements, will be deemed to accrue at the rate per
annum resulting after giving effect to the operation of such agreements. If the
Corporation or any Restricted Subsidiary directly or indirectly guarantees
Indebtedness of a third Person, the above definition will give effect to the
incurrence of such guaranteed Indebtedness as if the Corporation or any
Restricted Subsidiary had directly incurred or otherwise assumed such guaranteed
Indebtedness.

debt discount attributable to such period, (ii) the net cost under or otherwise
associated with Interest Rate Agreements or Currency Agreements including any

obligation, (iv) all commissions, discounts and other fees and charges owed with
respect to letters of credit and bankers' acceptance financing and (v) all
capitalized interest and all accrued interest, and (b) all but the principal

indirectly, by operation of the terms of its charter or any agreement,
instrument, judgment, decree, order, statute, rule or governmental regulation

     Owned Restricted Subsidiary (provided the Corporation or a Wholly-Owned
     Restricted Subsidiary is the survivor), as a result of or in connection
     with such Investment)

(any of the foregoing actions described in clauses (i) through (iv), other than
any such action that is a Permitted Payment (as defined below), collectively,
"Restricted Payments") (the amount of any such Restricted Payment, if other than
cash, shall be the Fair Market Value of the asset(s) proposed to be transferred
by the Corporation or such Restricted Subsidiary, as the case may be, in each
case, as determined in good faith by the Board of Directors, whose determination
shall be conclusive and evidenced by a board resolution), unless (l) immediately
after giving effect to such Restricted Payment on a pro forma basis, no Default
or Event of Default shall have occurred and be continuing; (2) immediately after
giving effect to such Restricted Payment on a pro forma basis, the Corporation
could incur $1.00 of additional Indebtedness (other than Permitted Indebtedness)
under the provisions of Section 2.02 of this First Supplemental Indenture and
(3) after giving effect to the proposed Restricted Payment, the aggregate amount
of all such Restricted Payments declared or made after the Issue Date, does not

                    the Corporation's last fiscal quarter ending prior to the
                    date of the Restricted Payment (or, if such aggregate
                    cumulative Consolidated Net Income shall be a deficit, minus
                    100% of such deficit);

                    Qualified Capital Stock of the Corporation (except, in each
                    case, to the extent such proceeds are used to purchase,

                    Indebtedness as set forth in clause (ii) or (iii) of
                    paragraph (b) below and excluding the net cash proceeds from
                    any issuance and sale of Qualified Capital Stock or from any
                    such exercises, in each case, financed, directly or
                    indirectly, using funds borrowed from the Corporation or any
                    Restricted Subsidiary until and to the extent such borrowing
                    is repaid);

                    thereon;

               (D)  in the case of the disposition or repayment of any
                    Investment constituting a Restricted Payment made after the
                    Issue Date, an amount (to the extent not included in
                    Consolidated Net Income) equal to the lesser of the return
                    of capital with respect to such Investment and the initial
                    amount of such Investment which was treated as a Restricted
                    Payment, in either case, less the cost of disposition of
                    such Investment and net of taxes; and

               (E)  so long as the Designation thereof was treated as a
                    Restricted Payment made after the Issue Date, with respect
                    to any Unrestricted Subsidiary that has been redesignated as

                    Supplemental Indenture, the Fair Market Value of the
                    interest of the Corporation and the Restricted Subsidiaries
                    in such Subsidiary, provided that such amount shall not in
                    any case exceed the Designation Amount with respect to such
                    Restricted Subsidiary upon its Designation.

     b.  Notwithstanding the foregoing, and in the case of clauses (ii) through
(vi) below, so long as no Default or Event of Default shall have occurred and be
continuing or would arise therefrom, the foregoing provisions shall not prohibit
the following actions (each of clauses (i) through (iv) being referred to as a
"Permitted Payment"):

          declaration thereof, if (A) at such date of declaration such payment
          was permitted by the provisions of the Indenture and (B) such payment
          shall have been deemed to have been paid on such date of declaration
          and shall have been deemed a "Restricted Payment" for purposes of the
          calculation required by paragraph (a) of this Section 2.03;

     (ii) the repurchase, redemption, or other acquisition or retirement of any

            Indebtedness (1) shall be in a principal amount that does not exceed
            the principal amount so repurchased, redeemed, defeased, retired,
            acquired or paid (or, if such Subordinated Indebtedness provides for
            an amount less than the principal amount thereof to be due and
            payable upon a declaration of acceleration thereof, then such lesser
            amount as of the date of determination), plus the lesser of (I) the
            stated amount of any premium or other payment required to be paid in
            connection with such repurchase, redemption, defeasance, retirement,

            payment to the Notes at least to the same extent as the Subordinated
            Indebtedness to be repurchased, redeemed, defeased, retired,
            acquired or paid;

     (v)    the purchase of stock or stock options from employees of the

purposes of clause (3) of paragraph (a) of this Section 2.03, Restricted
Payments under clauses (i) (as described in subclause (B) of such clause), (v)
and (vi) of paragraph (b) of this Section 2.03 shall be included.

     SECTION 2.04.  LIMITATION ON TRANSACTIONS WITH AFFILIATES.  The Corporation
will not, and will not cause or permit any Restricted Subsidiary to, directly or
indirectly, conduct any business or enter into or suffer to exist any contract,
agreement, arrangement or transaction with, or for the benefit of, any Affiliate
of the Corporation or of a Restricted Subsidiary (an "Affiliate Transaction") or
any series of related Affiliate Transactions (in either case, other than
Exempted Affiliate Transactions) (i) unless it is determined that the terms of
such Affiliate Transaction are fair and reasonable to the Corporation or such
Restricted Subsidiary, as applicable, and no less favorable to the Corporation
or such Restricted Subsidiary, as applicable, or to the  Corporation and its
Restricted Subsidiaries as a whole, than could have been obtained in an arm's-
length 

                                      -20-
<PAGE>
 
transaction with a non-Affiliate and (ii) if involving consideration to either
party in excess of $5 million, unless such Affiliate Transaction has been
approved by a majority of the members of the Board of Directors that are
disinterested in such transaction and (iii) if involving consideration to either
party in excess of $25 million, unless in addition to the foregoing, the
Corporation, prior to the consummation thereof, obtains a written favorable
opinion as to the fairness of such transaction to the Corporation, or such
Restricted Subsidiary, as applicable, from a financial point of view from an
independent investment banking firm of national reputation (or, if nationally
recognized investment banking firms do not customarily render opinions with
respect to transactions of such type, by a nationally recognized expert with
experience in evaluating the terms and conditions of transactions of such type).

     SECTION 2.05.  LIMITATION ON LIENS. The Corporation will not, and will not
cause or permit any Restricted Subsidiary to, directly or indirectly, create,
incur, assume, suffer to exist or affirm any Lien of any kind securing any (a)
Pari Passu Indebtedness or Subordinated Indebtedness (including any assumption,
guarantee or other liability with respect thereto by any Restricted Subsidiary)
upon any of its property or assets (including any intercompany notes), whether
owned on the Issue Date or acquired after the Issue Date, or any proceeds,
income or profits therefrom, or assign or convey any right to receive proceeds,
income or profits therefrom, unless the Notes are directly secured equally and
ratably with (or, in the case of Subordinated Indebtedness, prior or senior
thereto, with the same relative priority as the Notes shall have with respect to
such Subordinated Indebtedness) the obligation or liability secured by such
Lien, except for Liens (A) securing any Indebtedness which became Indebtedness
pursuant to a transaction permitted under Section 2.12 of this First
Supplemental Indenture or securing Acquired Indebtedness which, in each case,
were created prior to (and not created in connection with, or in contemplation
of) the incurrence of such Pari Passu Indebtedness or Subordinated Indebtedness
(including any assumption, guarantee or other liability with respect thereto by
any Restricted Subsidiary) and which Indebtedness is permitted under the
provisions of Section 2.02 of this First Supplemental Indenture or (B) securing
any Indebtedness  incurred in connection with any refinancing, renewal,
substitution or replacement of any such Indebtedness incurred in connection with
any Indebtedness described in clause (A) so long as the aggregate principal
amount of Indebtedness represented thereby is not increased by such refinancing
by an amount greater than the lesser of (i) the stated amount of any premium or
other payment required to be paid in connection with such a refinancing pursuant
to the terms of the Indebtedness being refinanced or (ii) the amount of premium
or other payment actually paid at such time to refinance the Indebtedness, plus,
in either case, the amount of expenses of the Corporation incurred in connection
with such refinancing; provided, however, that in the case of clauses (A) and
(B) any such Lien only extends (x) to the assets that were subject to such Lien
securing such Indebtedness prior to the related acquisition by the Corporation
or the Restricted Subsidiary or (y) in the case of assets constituting
receivables, extend to additional receivables of a similar nature and not
materially greater in value that the receivables securing such  Indebtedness
prior to the related acquisition by the  Corporation or the Restricted
Subsidiary, or (b) Senior Indebtedness which is incurred in violation of the
terms of the Indenture.

     SECTION 2.06.  LIMITATION ON INCURRENCE OF SENIOR SUBORDINATED
INDEBTEDNESS.  The Corporation will not, directly or indirectly, create, incur,
issue, assume, guarantee or otherwise in any manner become directly or
indirectly liable for or with respect to or otherwise permit to exist any
Indebtedness that is subordinate or junior in right of payment to any
Indebtedness of  the Corporation unless such Indebtedness is also (i) pari passu
with the Notes or subordinate or junior, in right of payment to the Notes and
(ii) does not have a Stated Maturity shorter than the final Stated Maturity of
the Notes.

     SECTION 2.07.  LIMITATION ON SALE OF ASSETS.  The Corporation will not, and
will not cause or permit any Restricted Subsidiary to, directly or indirectly,
consummate an Asset Sale unless (i) at least 80% of the consideration from such
Asset Sale is received in cash or Cash Equivalents or Eligible Securities and
(ii) the Corporation or such Subsidiary receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value of the shares or assets
subject to such Asset Sale.

                                      -21-
<PAGE>
 
     If all or a portion of the Net Cash Proceeds of any Asset Sale are not
required to be applied to repay permanently any Senior Indebtedness outstanding
as required by the terms thereof, or the Corporation determines not to apply
such Net Cash Proceeds to the permanent repayment of the Senior Indebtedness
which is required to be prepaid, or if no such Senior Indebtedness is then
outstanding, the Corporation or such Restricted Subsidiary may within 365 days
of such Asset Sale, invest the Net Cash Proceeds in capital expenditures,
properties and other assets that (as determined by the board of directors of the
Corporation) replace the properties and assets that were the subject of the
Asset Sale or in properties and assets that will be used in the businesses of
the Corporation or its Subsidiaries existing on the Issue Date or in businesses
reasonably related thereto.

     To the extent (i) the Corporation or a Restricted Subsidiary, as the case
may be, received more than 20% of the consideration from an Asset Sale in the
form of Eligible Securities (the fair market value (on the date of such Asset
Sale) of such amount in excess of 20% of the consideration is referred to herein
as the "Eligible Securities Proceeds") or (ii) all or part of the Net Cash
Proceeds of any Asset Sale are not applied, or the Corporation determines not to
so apply such Net Cash Proceeds, within 365 days of such Asset Sale as described
in the immediately preceding paragraph (such Net Cash Proceeds, the "Unutilized
Net Cash Proceeds" and together with the Eligible Securities Proceeds, the
"Excess Proceeds"), the Corporation shall, within 20 days after such 365th day
or at any earlier time after such Asset Sale, make an offer to purchase (the
"Asset Sale Offer") all outstanding Notes and any Pari Passu Indebtedness the
terms of which require such an offer to be made up to a maximum principal amount
(expressed as a multiple of $1,000) of Notes and such Pari Passu Indebtedness
equal to such Excess Proceeds, at a purchase price in cash equal to 100% of the
principal amount thereof, plus accrued and unpaid interest thereon, if any, to
the Purchase Date; provided, however, that the Asset Sale Offer may be deferred
until there are aggregate Excess Proceeds, equal to or in excess of $20 million,
at which time the entire amount of such Excess Proceeds and not just the amount
in excess of $20 million, shall be applied as required pursuant to this
paragraph.  An Asset Sale Offer will be required to be kept open for a period of
at least 20 business days.

     With respect to any Asset Sale Offer effected pursuant to this Section
2.07, among the Notes and such Pari Passu Indebtedness, to the extent the
aggregate principal amount of Notes and such Pari Passu Indebtedness tendered
pursuant to such Asset Sale Offer exceeds the Excess Proceeds to be applied to
the repurchase thereof, such Notes and such Pari Passu Indebtedness shall be
purchased pro rata based on the aggregate principal amount of such Notes and
such Pari Passu Indebtedness tendered.  To the extent the Excess Proceeds exceed
the aggregate amount of Notes and such Pari Passu Indebtedness tendered pursuant
to such Asset Sale Offer, the Corporation may retain and utilize any portion of
the Excess Proceeds not applied to repurchase the Notes and such Pari Passu
Indebtedness for any purpose consistent with the other terms of the Indenture
and such excess amount of Excess Proceeds shall not be included in any future
determination of Excess Proceeds.

     In the event that the Corporation makes an Asset Sale Offer, the
Corporation shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act, and any other applicable securities laws or
regulations and any applicable requirements of any securities exchange on which
the Notes are listed, and any violation of the provisions of the Indenture
relating to such Asset Sale Offer occurring as a result of such compliance shall
not be deemed a Default.

     SECTION 2.08.  LIMITATION ON PREFERRED STOCK OF RESTRICTED SUBSIDIARIES.
The Corporation will not (a) sell and will not cause or permit any Restricted
Subsidiary of the Corporation to issue, sell or transfer any Preferred Stock of
any Restricted Subsidiary (other than to the Corporation or to a Wholly-Owned
Restricted Subsidiary) or otherwise (b) permit any Person (other than the
Corporation or a Wholly-Owned Restricted Subsidiary) to own any Preferred Stock
of any Restricted Subsidiary, in each case, except for (i) Preferred Stock
issued or sold to, held by or transferred to the Corporation or a Wholly-Owned
Restricted Subsidiary, and (ii) Preferred Stock issued by a Person prior to the
time (A) such Person becomes a Restricted Subsidiary 

                                      -22-
<PAGE>
 
or (B) such Person merges with or into a Restricted Subsidiary, provided that
such Preferred Stock was not issued or incurred by such Person in anticipation
of the type of transaction contemplated by subclause (A) or (B).

     SECTION 2.09.  LIMITATION ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS
AFFECTING RESTRICTED SUBSIDIARIES.  The Corporation will not, and will not cause
or permit any Restricted Subsidiary to, directly or indirectly, create or
otherwise cause or suffer to exist or enter into any agreement with any Person
that would cause to become effective, any consensual encumbrance or restriction
of any kind, on the ability of any Restricted Subsidiary to (i) pay dividends,
in cash or otherwise, or make any other distribution on or in respect of its
Capital Stock or any other interest or participation in, or measured by, its
profits, to the Corporation or any other Restricted Subsidiary, (ii) pay any
Indebtedness owed to the Corporation or any other Restricted Subsidiary, (iii)
make any Investment in the Corporation or any other Restricted Subsidiary or
(iv) transfer any of its properties or assets to the Corporation or any other
Restricted Subsidiary, except for: (a) any encumbrance or restriction existing
under any agreement in effect on the Issue Date; (b) any encumbrance or
restriction, with respect to a Person that is not a Restricted Subsidiary of the
Corporation on the Issue Date, in existence at the time such Person becomes a
Restricted Subsidiary of the Corporation, and not incurred in connection with,
or in contemplation of, such Person becoming a Restricted Subsidiary; provided,
however, that such encumbrances and restrictions are not applicable to the
Corporation or any other Restricted Subsidiary, or the properties or assets of
the Corporation or any other Restricted Subsidiary; (c) customary provisions
restricting the subletting or assignment of any lease or the assignment of any
other contract to which the Corporation or any Restricted Subsidiary is a party,
which lease or contract is entered into in the ordinary course of business
consistent with past practice; (d) any encumbrance or restriction contained in
contracts for (x) sales of assets or stock permitted by Section 2.07 of this
First Supplemental Indenture or (y) the purchase of assets or stock which arises
out of an earn-out or similar arrangement; provided that, in each case, such
encumbrance or restriction relates only to assets being purchased or sold
pursuant to the contract containing such encumbrances or restriction; (e) any
encumbrance or restriction customarily contained in any security agreement or
mortgage which security  agreement or mortgage creates a Lien permitted under
this Indenture; provided that such encumbrance or restriction relates only to
assets subject to such Lien; and (f) any encumbrance or restriction existing
under any agreement that extends, renews, refinances or replaces the agreements
containing the encumbrances or restrictions in the foregoing clauses (a), (b),
(c) and (e), or in this clause (f), provided that the terms and conditions of
any such encumbrances or restrictions are not more restrictive in any material
respect than those under or pursuant to the agreement so extended, renewed,
refinanced or replaced.

     SECTION 2.10.  LIMITATIONS ON UNRESTRICTED SUBSIDIARIES.  The Corporation
may designate after the Issue Date any Subsidiary as an "Unrestricted
Subsidiary" under the Indenture (a "Designation") only if:

     (i)    no Default or Event of Default shall have occurred and be continuing
            at the time of or after giving effect to such Designation;

     (ii)   the Corporation would be permitted to make an Investment (other than
            a Permitted Investment) at the time of Designation (assuming the
            effectiveness of such Designation) pursuant to paragraph (a)(iv) of
            Section 2.03 in an amount (the "Designation Amount") equal to the
            Fair Market Value of the Corporation's interest in such Subsidiary
            on such date; and

     (iii)  the Corporation would be permitted under the Indenture to incur
            $1.00 of additional Indebtedness (other than Permitted Indebtedness)
            pursuant to Section 2.02 of this First Supplemental Indenture at the
            time of such Designation (assuming the effectiveness of such
            Designation).

                                      -23-
<PAGE>
 
     In the event of any such Designation, the Corporation shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to the
provisions set forth in Section 2.03 of this First Supplemental Indenture for
all purposes of the Indenture in the Designation Amount.

     The Corporation shall not, and shall not cause or permit any Restricted
Subsidiary to, at any time (x) provide credit support for or subject any of its
property or assets (other than the Capital Stock of any Unrestricted Subsidiary)
to the satisfaction of, any Indebtedness of any Unrestricted Subsidiary
(including any undertaking, agreement or instrument evidencing such
Indebtedness) or (y) be directly or indirectly liable for any Indebtedness of
any Unrestricted Subsidiary, except any non-recourse guarantee given solely to
support the pledge by the Corporation or any Restricted Subsidiary of the
Capital Stock of an Unrestricted Subsidiary.  All Subsidiaries of Unrestricted
Subsidiaries shall automatically be deemed to be Unrestricted Subsidiaries.

     The Corporation may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

     (A) no Default or Event of Default shall have occurred and be continuing at
         the time of and after giving effect to such Revocation; and

     (B) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding
         immediately following such Revocation would, if incurred at such time,
         have been permitted to be incurred for all purposes of the Indenture;
         and

     (C) any transaction (or series of related transactions) between such
         Subsidiary and any of its Affiliates that occurred while such
         Subsidiary was an Unrestricted Subsidiary would be permitted by Section
         2.04 of this First Supplemental Indenture as if such transaction (or
         series of related transactions) had occurred at the time of such
         Revocation.

     All Designations and Revocations must be evidenced by resolutions of the
Board of Directors delivered to the Trustee certifying compliance with the
foregoing provisions.

     SECTION 2.11.  PROVISION OF FINANCIAL STATEMENTS.  So long as the Notes are
outstanding, whether or not the Corporation is subject to Section 13(a) or 15(d)
of the Exchange Act, or any successor provision thereto, the Corporation will,
to the extent permitted by Commission practice and applicable law and
regulations, file with the Commission the annual reports, quarterly reports and
other documents which the Corporation would have been required to file with the
Commission pursuant to such Section 13(a) or 15(d), or any successor provision
thereto, if the Corporation were so subject, such documents to be filed with the
Commission on or prior to the date (the "Required Filing Dates") by which the
Corporation would have been required so to file such documents if the
Corporation were so subject. The Corporation will also in any event (x) within
15 days of each Required Filing Date, whether or not permitted or required to be
filed with the Commission, (i) transmit or cause to be transmitted by mail to
all Holders of the Notes and (ii) file with the Trustee, copies of the annual
reports, quarterly reports and other documents which the Corporation would have
been required to file with the Commission pursuant to Section 13(a) or 15(d) of
the Exchange Act, or any successor provision thereto, if the Corporation were
subject to either of such Sections and (y) if filing such documents by the
Corporation with the Commission is not permitted under the Exchange Act,
promptly upon written request and payment of the reasonable cost of duplication
and delivery, supply copies of such documents to any prospective Holder at the
Corporation's cost. In addition, for so long as any Notes remain outstanding,
the Corporation will furnish to the Holders of Notes and to securities analysts
and prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act, and, to any
beneficial Holder of Notes, if not obtainable from the Commission, information
of the type that would be filed with the Commission pursuant to the foregoing
provisions, upon the request of any such Holder. If any Subsidiaries' financial
statements would be required to be included in the financial

                                      -24-
<PAGE>
 
statements filed or delivered pursuant hereto if the Corporation were subject to
Section 13(a) or 15(d) of the Exchange Act, the Corporation shall include such
Subsidiaries' financial statements in any filing or delivery pursuant hereto.

     SECTION 2.12.  CONSOLIDATION, MERGER, SALE OF ASSETS, ETC. The Corporation
shall not, in any transaction or series of related transactions, merge or
consolidate with or into, or sell, assign, convey, transfer, lease or otherwise
dispose of all or substantially all of its properties and assets as an entirety
to, any Person or Persons, and the Corporation shall not permit any of the
Restricted Subsidiaries to enter into any such transaction or series of related
transactions if such transaction or series of related transactions, in the
aggregate, would result in a sale, assignment, conveyance, transfer, lease or
other disposition of all or substantially all of the properties and assets of
the Corporation and the Restricted Subsidiaries (determined on a consolidated
basis for the Corporation and the Restricted Subsidiaries), to any Person or
Persons, unless at the time and after giving effect thereto (i) either (A) (1)
if the transaction or transactions is a merger or consolidation involving the
Corporation, the Corporation shall be the Surviving Person of such merger or
consolidation or (2) if the transaction or transactions is a merger or
consolidation involving a Restricted Subsidiary, such Restricted Subsidiary
shall be the Surviving Person of such merger or consolidation, or (B) (1) the
Surviving Person shall be a corporation organized and existing under the laws of
the United States of America, any State thereof or the District of Columbia and
(2) in the case of a transaction involving the Corporation, the Surviving
Person, if other than the Corporation, shall expressly assume (unless such
obligations are otherwise assumed by operation of law) by a Supplemental
Indenture executed and delivered to the Trustee, all the obligations of the
Corporation under the Notes and the Indenture, and in each case, the Indenture
and the Notes shall remain in full force and effect; (ii) immediately after
giving effect to such transaction or series of related transactions on a pro
forma basis, no Default or Event of Default shall have occurred and be
continuing; and (iii) the Corporation, or the Surviving Person, as the case may
be, immediately after giving effect to such transaction or series of related
transactions on a pro forma basis (including, without limitation, any
Indebtedness incurred or anticipated to be incurred in connection with or in
respect of such transaction or series of transactions), could incur $1.00 of
additional Indebtedness (other than Permitted Indebtedness) under the provisions
of Section 2.02 of this First Supplemental  Indenture, and at the time of the
transaction if any of the property or assets of the Corporation or any of its
Restricted Subsidiaries would thereupon become subject to any Lien, the
provisions of Section 2.05 of this First Supplemental Indenture are complied
with.

     Upon any consolidation or merger of the Corporation or any transfer of all
or substantially all of the assets of the Corporation in accordance with the
foregoing, in which the Corporation is not the Surviving Person, the Surviving
Person shall succeed to, and be substituted for, and may exercise every right
and power of, the Corporation under the Indenture and the Notes with the same
effect as if such successor corporation had been named as the Corporation
therein; and thereafter, except in the case of (a) a lease or (b) any sale,
assignment, conveyance, transfer, lease or other disposition to a Restricted
Subsidiary of the Corporation, the Corporation shall be discharged from all
obligations and covenants under the Indenture.

     For all purposes of the Indenture and the Notes (including the provision of
this Section 2.12 and Sections 2.02, 2.03 and 2.05 of this First Supplemental
Indenture), Subsidiaries of any Surviving Person shall, upon such transaction or
series of related transactions, become Restricted Subsidiaries unless and until
designated as Unrestricted Subsidiaries pursuant to and in accordance with the
provisions of Section 2.10 of this First Supplemental Indenture and all
Indebtedness, and all Liens on property or assets, of the Corporation and the
Restricted Subsidiaries in existence immediately prior to such transactions or
series of related transactions will be deemed to have been incurred upon such
transaction or series of related transactions.

     Notwithstanding anything to the contrary in this Section 2.12, a Restricted
Subsidiary may merge with or into another Restricted Subsidiary.

                                      -25-

     SECTION 2.13.  PAYMENT OF TAXES AND OTHER CLAIMS.  Except with respect to
immaterial items, the Corporation shall, and shall cause each of its
Subsidiaries to, pay or discharge or cause to be paid or discharged, before the
same shall become delinquent, (i) all taxes, assessments and governmental
charges (including withholding taxes and any penalties, interest and additions
to taxes) levied or imposed upon the Corporation or any of its Subsidiaries or
any of their respective properties and assets and (ii) all lawful claims,
whether for labor, materials, supplies, services or anything else, which have
become due and payable and which by law have or may become a lien upon the
property and assets of the Corporation or any of its Subsidiaries; provided,
however, that neither the Corporation nor any Subsidiary shall be required to
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings and for which such disputed amounts the
need for adequate reserves has been reviewed in accordance with GAAP.

     SECTION 2.14.  MAINTENANCE OF PROPERTIES AND INSURANCE.  The Corporation
shall cause all material properties used or useful to the conduct of its
business and the business of each of its Subsidiaries to be maintained and kept
in good condition, repair and working order (reasonable wear and tear excepted)
and supplied with all necessary equipment and shall cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in their reasonable judgment may be necessary, so that the business
carried on in connection therewith may be properly conducted at all times;
provided,  however, that nothing in this Section 2.14 shall prevent the
Corporation or any Subsidiary from discontinuing any operation or maintenance of
any of such properties, or disposing of any of them, if such discontinuance or
disposal is in the judgment of the Corporation, desirable in the conduct of the
business of such entity.

     The Corporation shall provide, or cause to be provided, for itself and each
of its Subsidiaries, insurance (including appropriate self-insurance) against
loss or damage of the kinds that, in the reasonable, good faith opinion of the
Corporation is adequate and appropriate for the conduct of the business of the
Corporation and such Subsidiaries in a prudent manner, with (except for self-
insurance) reputable insurers or with the government of the United States of
America or an agency or instrumentality thereof, in such amounts, with such
deductibles, and by such methods as shall be customary, in the reasonable, good
faith opinion of the Corporation and adequate and appropriate for the conduct of
the business of the Corporation and such Subsidiaries in a prudent manner for
entities similarly situated in the industry, unless failure to provide such
insurance (together with all other such failures) would not have a material
adverse effect on the financial condition or results of operations of the
Corporation and such Subsidiaries considered as a whole.

     SECTION 2.15.  STAY, EXTENSION AND USURY LAWS.  The Corporation covenants
(to the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law or other law which would prohibit or
forgive the Corporation from paying all or any portion of the principal of
(premium, if any) or interest on the Notes as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture and the Corporation (to the
extent it may lawfully do so) hereby expressly waives all benefit or advantage
of any such law, and covenants that it will not, by resort to any such law,
hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law has been enacted.

     SECTION 2.16.  LIMITATION ON STATUS AS INVESTMENT COMPANY.  Neither the
Corporation nor any of its Restricted Subsidiaries shall become an "investment
company," as that term is defined in the Investment Company Act of 1940, as
amended, or otherwise become subject to regulation thereunder.

                               TERMS OF THE NOTES

     SECTION 3.01.  TERMS OF THE NOTES.  A Series of Securities in the aggregate
principal amount of One Hundred Seventy-Five Million Dollars ($175,000,000) to
be issued under the Original Indenture, as supplemented by this First
Supplemental Indenture, is hereby created, and such Series of Securities is
hereby designated the "8-7/8% Senior Subordinated Notes Due 2006".  The Notes
shall mature on June 1, 2006 and shall bear interest at the rate of 8-7/8% per
annum from  the most recent date to which interest has been paid or, if no
interest has been paid, from the Issue Date.  Interest on the Notes shall be
payable semiannually on each June 1 and December 1, commencing December 1, 1998,
to the Holders of record on the Record Date.

     The Notes shall be issued initially as a single Global Note, in registered
form, registered in the name of The Depositary Trust Corporation, as Depository,
or its nominee,, and otherwise substantially as in the form set forth in Exhibit
A to this First Supplemental Indenture with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by
the Indenture.  The Global Note shall be exchangeable for definitive Notes in
registered form substantially the same as the Global Note in denominations of
$1,000 or any integral multiple thereof upon the terms of and in accordance with
the provisions of the  Indenture.

     The Notes shall be payable (as to both principal and interest) when and as
the same become due at the office of the  Trustee located in New York City, New
York, provided that,  so long as the Notes are in the form of one or more Global
Notes, payments of interest may be made by wire transfer in accordance with the
Letter of Representations and provided further, that upon any exchange of the
Global Notes for Notes in definitive form, the Corporation elects to exercise
its option to have interest payable by check mailed to the registered owners at
such owners' addresses as they appear on the Register, as kept by the Trustee on
each relevant Record Date.

     The Record Dates for the Notes shall be May 15 and November 15 of each
year.

     SECTION 3.02.  REDEMPTION OF THE NOTES.  (a)  Optional Redemption.  The
Notes will be redeemable at the option of the Corporation, in whole or in part,
at any time on or after June 1,  2002, at the redemption prices (expressed as
percentages of principal amount) set forth below, plus accrued and unpaid
interest thereon, if any, to the date of redemption, if redeemed during the 12-
month period beginning on June 1 of the years indicated below:

<TABLE> 
<CAPTION> 
     YEAR                                REDEMPTION PRICE
     ----                                ----------------
     <S>                                 <C> 
     2002..............................       104.438%
     2003..............................       102.958%
     2004..............................       101.479%
     2005 and thereafter...............       100.000%
</TABLE> 

     (b)  Optional Redemption upon Public Equity Offering.  On or prior to June
1, 2001, the Corporation may, at its option, use the net proceeds of a Public
Equity Offering to redeem up to 35% of the originally issued aggregate principal
amount of the Notes, at a redemption price in cash equal to 108-7/8% of the
principal amount thereof, plus accrued and unpaid interest thereon, if any, to
the date of redemption; provided, however, that at least $113,750,000 in
aggregate principal amount of Notes is outstanding following such redemption.
Notice of any such redemption must be given not later than 30 days after the
consummation of the Public Equity Offering.

                                      -27-
<PAGE>
 
     As used in the preceding paragraph, a "Public Equity Offering" means any
underwritten public offering of Capital Stock (other than Redeemable Capital
Stock) of the Corporation made on a primary basis by the Corporation pursuant to
a registration statement filed with and declared effective by the Commission in
accordance with the Securities Act.

     (c)  Selection and Notice.  In the event that less than all of the Notes
are to be redeemed at any time, selection of Notes for redemption shall be made
by the Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes are
not listed on a national securities exchange, on a pro rata basis, by lot or by
such method as the Trustee will deem fair and appropriate; provided, however,
that no Notes of a principal amount of $1,000 or less shall be redeemed in part.
Notice of redemption will be mailed by first class mail at least 30 but no more
than 60 days before the redemption date to each Holder of Notes to be redeemed
at its registered address.  If any Note is to be redeemed in part only, the
notice of redemption that relates to such Note will state the portion of the
principal amount thereof to be redeemed.  A new Note in a principal amount equal
to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Note.  On and after the  Redemption
Date, interest will cease to accrue on Notes or portions thereof called for
redemption so long as the  Corporation has deposited with the  Paying Agent for
the Notes funds in satisfaction of the applicable  Redemption Price.

     SECTION 3.03  CHANGE OF CONTROL.  Following the occurrence of a Change of
Control (the date of such occurrence being the "Change of Control Date"), the
Corporation, within 20 Business Days following the Change of Control Date, shall
make an irrevocable and unconditional offer to purchase (a "Change of Control
Offer") all of the then outstanding Notes on a date (the "Change of Control
Purchase Date") that is no later than 50 Business Days after the occurrence of
such Change of Control at a purchase price (the "Change of Control Purchase
Price") in cash equal to 101% of the principal amount thereof, plus accrued and
unpaid interest thereon, if any, to the Change of  Control Purchase Date.  The
Corporation shall purchase all Notes properly tendered into the Change of
Control Offer and not withdrawn.

     In order to effect such Change of Control Offer, the Corporation, not later
than the 20/th/ business day after the Change of Control Date, shall mail to
each Holder of Notes notice of the Change of Control Offer, which notice will
govern the terms of the Change of Control Offer and will state, among other
things, the procedures that Holders must follow to accept the Change of Control
Offer.  The Change of Control Offer will be kept open for a period of at least
20 business days.

     On or before the Change of Control Purchase Date, the Corporation will
deposit with the Trustee cash sufficient to pay the Change of Control Purchase
Price (together with any  accrued and unpaid  interest) for all Notes to be
tendered pursuant to the Change of Control Offer.  On the Change of Control
Purchase Date, the Trustee shall pay the Change of Control Purchase Price to all
Holders tendering their Notes for purchase.

                     SUBORDINATION PROVISIONS APPLICABLE TO
                                   THE NOTES

     SECTION 4.01.  NOTES SUBORDINATE TO SENIOR INDEBTEDNESS.  The Corporation
covenants and agrees, and each  Holder of  the Notes, by such  Holder's
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article Four (subject to the provisions
of Article Six of this First Supplemental Indenture), the  Indebtedness
represented by the Notes and the payment of the principal of (and premium, if
any) and interest on each and all of the Notes  is hereby expressly made

                                      -28-
<PAGE>
 
subordinate and subject in right of payment to the prior payment in full in cash
or Cash Equivalents of all Senior Indebtedness whether outstanding on the Issue
Date or incurred thereafter.

     SECTION 4.02.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.  In the
event of (1) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relating to the Corporation or to its creditors, as such,
or to a substantial part of its assets, or (2) any liquidation, dissolution or
other winding up of the Corporation, whether voluntary or involuntary and
whether or not involving insolvency or bankruptcy, or (3) any assignment for the
benefit of creditors or any other marshalling of assets  or liabilities of the
Corporation, then and in any such event specified in (1), (2) or (3) above (each
such event, if any, herein sometimes referred to as a "Proceeding") the holders
of Senior Indebtedness shall be entitled to receive payment in full of all
amounts due or to become due on or in respect of all Senior Indebtedness, or
provision shall be made for such payment in cash or  Cash Equivalents or
otherwise in a manner satisfactory to the holders of Senior Indebtedness, before
the  Holders of the Notes are entitled to receive any payment or distribution of
any kind or character, whether in cash, property or securities, on account of
principal of (or premium, if any) or interest on the Notes or on account of any
purchase or other acquisition of Notes by the Corporation or any Subsidiary of
the Corporation (all such payments, distributions, purchases and acquisitions
herein referred to, individually and collectively, as a "Notes Payment"), and to
that end, the holders of all Senior Indebtedness shall be entitled to receive,
for application to the payment thereof, any Notes Payment which may be otherwise
payable or deliverable in respect of the Notes in any such Proceeding.

     In the event that, notwithstanding the foregoing provisions of this Section
4.02, the Trustee or the  Holder of any Note shall have received any Notes
Payment before all Senior Indebtedness is paid in full or payment thereof
provided for in cash or Cash Equivalents or otherwise in a manner satisfactory
to the holders of Senior Indebtedness, and if such fact shall, at or prior to
the time of such Notes Payment, have been made known to the Trustee or, as the
case may be, such  Holder, then and in such event, such Notes Payment shall be
paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Corporation for application to the payment of
all Senior Indebtedness remaining unpaid, to the extent necessary to pay all
Senior Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

     For purposes of this Article Four only, the words "any payment or
distribution of any kind or character, whether in cash, property or securities"
shall not be deemed to include a payment or distribution of stock or securities
of the Corporation provided for by a plan of reorganization or readjustment
authorized by an order or decree of a court of competent jurisdiction in a
reorganization proceeding under any applicable bankruptcy law or of any other
corporation provided for by such plan of reorganization or readjustment, which
stock or securities are subordinated in right of payment to all then outstanding
Senior Indebtedness to substantially the same extent as, or to a greater extent
than, the Notes are so subordinated as provided in this Article  Four.  The
consolidation of the Corporation with, or the merger of the Corporation into,
another Person or the liquidation or dissolution of the Corporation following
the conveyance or transfer of all or substantially all of its properties and
assets as an entirety to another Person upon the terms and conditions set forth
in Section 2.12 of this First Supplemental Indenture shall not be deemed a
Proceeding for the purposes of this Section 4.02 if the Person formed by such
consolidation or into which the Corporation is merged or the Person which
acquires by conveyance or transfer such properties and assets substantially as
an entirety, as the case may be, shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions set forth in such Section
2.12 of this First Supplemental Indenture.

     SECTION 4.03.  PRIOR PAYMENT TO SENIOR INDEBTEDNESS UPON ACCELERATION OF
NOTES.  In the event that any Notes are declared due and payable before their
Stated Maturity, then and in such event, the holders of the Senior Indebtedness
outstanding at the time such Notes so become due and payable shall be entitled

                                      -29-
<PAGE>
 
to receive payment in full of all amounts due or to become due on or in respect
of all Senior Indebtedness, or provision shall be made for such payment in cash
or Cash Equivalents or otherwise in a manner satisfactory to the holders of such
Senior Indebtedness, before the  Holders of the Notes are entitled to receive
any Notes Payment (including any payment which may be payable by reason of the
payment of any other indebtedness of the Corporation being subordinated to the
payment of the Notes).

     In the event that, notwithstanding the foregoing, the Corporation shall
make any Notes Payment to the Trustee or any Holder of Notes prohibited by the
foregoing provisions of this Article Four, and if such fact shall, at or prior
to the time of such Notes Payment, have been made known to the Trustee pursuant
to Section 4.10 or, as the case may be, such  Holder, then and in such event,
such Notes Payment shall be paid over and delivered forthwith to the
Corporation.

     The provisions of this Section 4.03 shall not apply to any Notes Payment
with respect to which  Section 4.02 would be applicable.

     SECTION 4.04.  NO PAYMENT IN CERTAIN CIRCUMSTANCES.  (a) During the
continuance of any default in the payment of any Senior Indebtedness beyond any
applicable grace period pursuant to which the maturity thereof may immediately
be accelerated, no payment or distribution of any assets of the  Corporation of
any kind or character (other than capital stock of the Corporation or other
securities of the Corporation that are subordinated to Senior Indebtedness to at
least the same extent as the Notes) shall be made on account of the Subordinated
Obligations, or the purchase, redemption or other acquisition of, the Notes
unless and until such default has been cured or waived or has ceased to exist or
such Senior Indebtedness shall have been discharged or paid in full.

     (b)   During the continuance of any non-payment default with respect to any
Designated Senior Indebtedness pursuant to which the maturity thereof may
immediately be accelerated (a "Non-payment Default") and (x) after the receipt
by the Trustee from the representatives of such Designated Senior Indebtedness
of a written notice of such Non-payment Default or (y) if the Non-payment
Default results from the acceleration of the Notes, from the date of such
acceleration, no payment or distribution of any assets of the  Corporation of
any kind or character (other than capital stock of the Corporation or other
securities of the Corporation that are subordinated to Senior Indebtedness to at
least the same extent as the Notes) shall be made by the  Corporation on account
of the Subordinated Obligations, or the purchase, redemption or other
acquisition of, the Notes for the period specified below (the "Payment Blockage
Period").

     The Payment Blockage Period will commence upon (x) the receipt of notice of
a Non-payment Default by the Trustee from the representatives of holders of
Designated Senior Indebtedness or (y) if the Non-payment Default results from
the acceleration of the Notes, upon such acceleration, and will end on the
earliest to occur of the following events:  (i) 179 days shall have elapsed (A)
since the receipt of such notice of Non-payment Default or (B) if the Non-
payment Default results from the acceleration of the Notes, since such
acceleration (in each case, provided that such Designated Senior Indebtedness
shall not theretofore have been accelerated and the Corporation has not
defaulted with respect to the payment of such Designated Senior Indebtedness),
(ii) such default is cured or waived or ceases to exist or such Designated
Senior Indebtedness is discharged or (iii) such Payment Blockage Period shall
have been terminated by written notice to the  Corporation or the Trustee from
the representatives of Designated Senior Indebtedness initiating such Payment
Blockage Period.  After the end of any Payment Blockage Period, the  Corporation
shall promptly resume making any and all required payments in respect of the
Notes, including any missed payments.  Notwithstanding anything in the
subordination provisions of the Indenture or the Notes to the contrary, (x) in
no event shall a Payment Blockage Period extend beyond 179 days from the date
such Payment Blockage Period was commenced and (y) there shall be a period of at
least 186 consecutive days in each 365-day period when no Payment Blockage
Period is in effect.  A Non-payment Default with respect to Designated Senior
Indebtedness that existed or was continuing on the date of the commencement of
any 

                                      -30-
<PAGE>
 
Payment Blockage Period with respect to the Designated Senior Indebtedness
initiating such Payment Blockage Period cannot be made the basis for the
commencement of a second Payment Blockage Period, whether or not within a period
of 365 consecutive days, unless such default has been cured or waived for a
period of not less than 90 consecutive days and subsequently recurs.

     In the event that, notwithstanding the foregoing, the Corporation shall
make any Notes Payment to the Trustee or any  Holder of Notes prohibited by the
foregoing provisions of this Section 4.04, and if such fact shall, at or prior
to the time of such Notes Payment, have been made known to the Trustee or, as
the case may be, such Holder, then and in such event, such Notes Payment shall
be paid over and delivered forthwith to the Corporation.

     The Trustee shall give prompt written notice to the Corporation of any
notice from a holder of Senior Indebtedness received by the Trustee pursuant to
Section 4.10 which would prohibit the making of any payment to or by the Trustee
with respect to any Notes.

     The provisions of this Section 4.04 shall not apply to any Notes Payment
with respect to which Section 4.02 would be applicable.

     SECTION 4.05.  PAYMENT PERMITTED IF NO DEFAULT.  Nothing contained in this
Article  Four or elsewhere in the Indenture or in any of the Notes shall prevent
(1) the Corporation, at any time except during the pendency of any Proceeding
referred to in Section  4.02 or under the conditions described in Sections 4.03
or 4.04, from making Notes Payments, or (2) the application by the Trustee of
any money deposited with it hereunder to Notes Payments or the retention of such
Notes Payment by   Holders of Notes, if, at the time of such application by the
Trustee, it did not have knowledge that such Notes Payment would have been
prohibited by the provisions of this Article  Four.

     SECTION 4.06.  SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.
Subject to the payment in full of all amounts due or to become due on or in
respect of Senior Indebtedness, or the provision for such payment in cash or
Cash Equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, the  Holders of Notes shall be subrogated to the extent of the
payments or distributions made to the holders of such Senior Indebtedness
pursuant to the provisions of this Article Four (equally and ratably with the
holders of all  Indebtedness of the Corporation which by its express terms is
subordinated to  Indebtedness of the Corporation to substantially the same
extent as the Notes are subordinated and is entitled to like rights of
subrogation) to the rights of the holders of such Senior Indebtedness to receive
payments and distributions of cash, property and securities applicable to the
Senior Indebtedness until the principal of (and premium, if any) and interest on
the Notes shall be paid in full.  For purposes of such subrogation, no payments
or distributions to the holders of the Senior Indebtedness of any cash, property
or securities to which the  Holders of Notes or the Trustee would be entitled
except for the provisions of this Article  Four, and no payments over pursuant
to the provisions of this Article  Four to the holders of Senior Indebtedness by
Holders of Notes or the Trustee, shall, as among the Corporation, its creditors
other than holders of Senior Indebtedness and the  Holders of the Notes, be
deemed to be a payment or distribution by the Corporation to or on account of
the Senior Indebtedness.

     SECTION  4.07.  PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.  The
provisions of this Article  Four are and are intended solely for the purpose of
defining the relative rights of the   Holders of the Notes on the one hand and
the holders of Senior Indebtedness on the other hand.  Nothing contained in this
Article  Four or elsewhere in this First Supplemental Indenture or in the Notes
is intended to or shall (1) impair, as among the Corporation, its creditors
other than holders of Senior Indebtedness and the Holders of Notes, the
obligation of the Corporation, which is absolute and unconditional, to pay to
the Holders of Notes the principal of (and premium, if any) and interest on the
Notes as and when the same shall become due and payable in accordance with the
terms hereof; or (2) affect the relative rights against the Corporation of the
Holders of 

                                      -31-
<PAGE>
 
Notes and creditors of the Corporation other than the holders of Senior
Indebtedness; or (3) prevent the Trustee or the Holder of any Note from
exercising all remedies otherwise permitted by applicable law upon default under
the Indenture, subject to the rights, if any, under this Article Four of the
holders of Senior Indebtedness to receive cash, property and securities
otherwise payable or deliverable to the Trustee or such Holder.

     SECTION 4.08.  TRUSTEE TO EFFECTUATE SUBORDINATION AND PAYMENT PROVISIONS.
Each  Holder of a Note by acceptance thereof authorizes and directs the Trustee
to take such action as may be necessary or appropriate to effectuate the
subordination and payment provisions provided in this Article  Four and appoints
the Trustee such  Holder's attorney-in-fact for any and all such purposes.

     SECTION 4.09.  NO WAIVER OF SUBORDINATION PROVISIONS.  No right of any
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Corporation or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the
Corporation with the terms, provisions and covenants of the Indenture,
regardless of any knowledge thereof any such holder may have or be otherwise
charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Trustee or the  Holders of the Notes, without
incurring responsibility to the  Holders of the Notes and without impairing or
releasing the subordination provided in this Article  Four or the obligations
hereunder of the  Holders of Notes to the holders of Senior Indebtedness, do any
one or more of the following:  (i) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, Senior Indebtedness, or
otherwise amend or supplement in any manner Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any
Person liable in any manner for the collection of Senior Indebtedness; and (iv)
exercise or refrain from exercising any rights against the Corporation and any
other Person.

     SECTION 4.10.  NOTICE TO TRUSTEE.  The Corporation shall give prompt
written notice to the Trustee of any fact known to the Corporation which would
prohibit the making of any payment to or by the Trustee in respect of the Notes.
Notwithstanding the provisions of this Article  Four or any other provision of
the Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts which would prohibit the making of any payment to or by the Trustee
in respect of the Notes, unless and until the Trustee shall have received
written notice thereof from the Corporation or a holder of Senior Indebtedness
or from any trustee therefor; and, prior to the receipt of any such written
notice, the Trustee, subject to the provisions of Section 7.01 of the Original
Indenture, shall be entitled in all respects to assume that no such facts exist;
provided, however, that if the Trustee shall not have received the notice
provided for in this Section 4.10 at least three Business Days prior to the date
upon which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of (and premium, if
any) or interest on, or amounts payable upon redemption or repurchase of, any
Note), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary which may be received by it within three
Business Days prior to such date.

     Subject to the provisions of Section 7.01 of the Original Indenture, the
Trustee shall be entitled to rely on the delivery to it of a written notice by a
Person representing himself to be a holder of Senior Indebtedness (or a trustee
therefor) to establish that such notice has been given by a holder of Senior
Indebtedness (or a trustee therefor).  In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Indebtedness to participate in any payment or

                                      -32-
<PAGE>
 
distribution pursuant to this Article Four, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of Senior Indebtedness held by such Person, the extent to which such
person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such Person under this Article Four, and if
such evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

     SECTION 4.11. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT.  Upon any payment or distribution of assets of the Corporation referred
to in this Article  Four, the Trustee, subject to the provisions of Section 7.01
of the Original Indenture, and the  Holders of Notes shall be entitled to rely
upon any order or decree entered by any court of competent jurisdiction in which
such Proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of Notes, for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of the
Senior Indebtedness and other indebtedness of the Corporation, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Four.

     SECTION 4.12.  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness and shall not be liable to any such holders if it shall in
good faith mistakenly pay over or distribute to  Holders of Notes or to the
Corporation or to any other Person cash, property or securities to which any
holders of Senior Indebtedness shall be entitled by virtue of this Article  Four
or otherwise.

     SECTION 4.13.  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS;
PRESERVATION OF TRUSTEE'S RIGHTS.  The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article  Four with respect to
any Senior Indebtedness which may at any time be held by it, to the same extent
as any other holder of Senior Indebtedness, and nothing in the Indenture shall
deprive the Trustee of any of its rights as such holder.

     SECTION 4.14.  ARTICLE APPLICABLE TO PAYING AGENTS.  In case at any time
any Paying Agent other than the Trustee shall have been appointed by the
Corporation and be then acting hereunder, the term "Trustee" as used in this
Article  Four shall in such case (unless the context otherwise requires) be
construed as extending to and including such Paying Agent within its meaning as
fully for all intents and purposes as if such Paying Agent were named in this
Article Four in addition to or in place of the Trustee.

<PAGE>
 
          Trustee and the Corporation (an "Acceleration Notice"), may declare

         subject thereto);

     (d) waive a default in the payment of principal of, premium, if any, or
         interest on, or redemption payment with respect to, the Notes (except a

         provided in the Indenture and a waiver of the payment default that
         resulted from such acceleration);

     (e) modify the ranking or priority of any Note; or

     (f) following the occurrence of a Change of Control or Asset Sale, modify
         the provisions of any covenant (or the related definitions) in the
         Indenture requiring the Corporation to make and consummate a Change of
         Control Offer in respect of such Change of Control or Asset Sale Offer
         in respect of an Asset Sale or modify any of the provisions or

                            MISCELLANEOUS PROVISIONS

     SECTION 8.01. PROVISIONS OF THE ORIGINAL INDENTURE. Except insofar as
herein otherwise expressly provided, all the definitions, provisions, terms and
conditions of the  Original Indenture shall be deemed to be incorporated in and
made a part of this First Supplemental Indenture; and the Original Indenture, as
amended and supplemented by this First Supplemental Indenture, is in all
respects ratified and confirmed, and the Original Indenture and this First
Supplemental Indenture shall be read, taken and considered as one and the same
instrument for all purposes and every  Holder of the Notes authenticated and
delivered under the Indenture shall be bound hereby; provided, however, that to
the extent terms or provisions of this First Supplemental Indenture conflict
with or are inconsistent with terms or provisions in the Original Indenture, the
terms and provisions of this First Supplemental Indenture shall govern.

     SECTION 8.02.  LIMITATION OF SUITS BY HOLDERS OF NOTES.  No Holder of any
Notes shall have any right by virtue of any provision of the Indenture to

or for any other remedy hereunder, unless such Holder previously shall have
given to the Trustee written notice of a 

                                      -38-
<PAGE>
 
continuing Event of Default as provided in the Indenture, and unless also the
Holders of not less that 25% in principal amount of the Notes then outstanding
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as Trustee and shall have offered to the Trustee
such reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby (including the reasonable fees of
counsel for the Trustee), and the Trustee, for 15 days after its receipt of such
notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding and no direction inconsistent with
such written request shall have been given to the Trustee pursuant to this
Section 8.02; it being understood and intended, and being expressly covenanted
by the taker and Holder of every Security with every other taker and Holder and
the Trustee, that no one or more Holders of Securities shall have any right in
any manner whatever by virtue or by availing of any provision of this Indenture
to affect, disturb or prejudice the rights of the Holders of any other of such
Securities, or to obtain or seek to obtain priority over or preference to any
other such Holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
Holders of Securities. For the protection and enforcement of the provisions of
this Section 8.02, each and every Holder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

     SECTION 8.03.  SEPARABILITY OF INVALID PROVISIONS.  In case any one or more
of the provisions contained in this First Supplemental Indenture should be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions contained in this First
Supplemental Indenture, and to the extent and only to the extent that any such
provision is invalid, illegal or unenforceable, this First Supplemental
Indenture shall be construed as if such provision had never been contained
herein.

                                      -39-

     SECTION 8.04.  EXECUTION IN COUNTERPARTS.  This First Supplemental

                        CB RICHARD ELLIS SERVICES, INC.
                     8 7/8% SENIOR SUBORDINATED NOTE DUE 2006


This Note is one of a duly authorized issue of securities of CB Richard Ellis,
not limited in aggregate principal amount, all issued or to be issued in one or
more series of varying dates, numbers, interest rates and other provisions,
under an Indenture dated as of May 26, 1998, as amended by the First
Supplemental Indenture dated as of May 26, 1998, (such Indenture as so amended
being herein referred to as the "Indenture"), each being between CB Richard
Ellis and the Trustee.  Capitalized terms used and not otherwise defined herein
have the meaning set forth in the Indenture.  This Note is one of a series of
Notes designated as its "8 7/8% Senior Subordinated Notes Due 2006" aggregating
$175,000,000 in principal amount (herein called the "Notes").

Reference is hereby made to the Indenture and all indentures supplemental
thereto for a description of the rights, obligations, duties and immunities
thereunder of CB Richard Ellis, the Trustee and the Holders of the Notes, to all
of the provisions of which Indenture the registered owner of this Note, by
acceptance hereof, assents and agrees.  The Indenture contains provisions
permitting CB Richard Ellis and the Trustee, with the consent of the Holders of
not less than a majority in aggregate principal amount of the Securities (which
term is defined in the Indenture as any security or securities of CB Richard
Ellis, authenticated and delivered under the Indenture) at the time Outstanding
and affected by such supplemental indenture (voting as one class), to execute
one or more supplemental indentures for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Indenture
or of any supplemental indenture or of modifying in any manner the rights of the
Holders of such Securities; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
(including the Notes) affected thereby: (1) change the fixed maturity or
redemption date of any Note, or reduce the rate of interest on any Note or the
method of determining such rate of interest or extend the time of payment of
interest, or reduce the principal amount thereof, or reduce any premium payable
on the redemption thereof, or change the coin or currency in which the Notes or
the interest thereon is payable or impair the right to institute suit for the
enforcement of any such payment on or after the maturity thereof (or, in the
case of redemption, on or after the redemption date), (2) reduce the aforesaid
percentage of Holders of the Outstanding Securities whose consent is required
for the execution of such supplemental indenture, or the consent of the Holders
of which is required for any waiver provided for in the Indenture, (3) change
the time of payment or reduce the amount of any minimum sinking account or fund
payment or (4) modify any provisions of the Indenture relating to the amendment
thereof or the creation of a supplemental indenture (except to increase the
rights of the Holders).  It is also provided in the Indenture that the Holders
of a majority in principal amount of the Notes may waive any past Event of
Default with respect to the Notes and its consequences, except a continuing
default in the payment of the principal of or interest on the Notes or in
respect of a covenant or provision of the Indenture which cannot be modified or
amended without the consent of the registered owner of each Note so affected.
In addition, the First Supplemental Indenture provides that no  modification or
amendment of the Indenture or the Notes may be made without the consent of the
Holder of each Outstanding Note affected thereby to (a) alter the optional
redemption or repurchase provisions of any such Note or the Indenture in a
manner adverse to the Holders of the Notes, (b) change the place of payment of
principal of (or premium on) or interest on any such Note;, (c) modify any
provision of the Indenture relating to the waiver of past defaults (other than
to add sections of the Indenture or the Notes subject thereto), (d) waive a
default in the payment of the principal of, premium, if any, or interest on, or
redemption payment with respect to, the Notes (except a rescission or
acceleration of the Notes by the Holders thereof as provided in the Indenture
and a waiver of a payment default that resulted from such acceleration), (e)
modify the ranking or priority of any Note or (f) following the occurrence of a
Change of Control or Asset Sale, modify the provisions of any covenant (or the
related definitions) in the Indenture requiring the Corporation to make and
consummate a Change of Control Offer in respect of such Change of 

                                      -43-
<PAGE>
 
Control or Asset Sale Offer in respect of an Asset Sale or modify any of the
provisions or definitions with respect thereto in a manner materially adverse to
the Holders of each outstanding Note affected thereby.

The Notes will be redeemable, at the option of CB Richard Ellis, in whole or in
part, at any time on or after June 1, 2002, at the redemption prices (expressed
as a percentage of principal amount) set forth herein, together with accrued and
unpaid interest thereon, if any, to the date of redemption, if redeemed during
the 12-month period beginning on June 1 of the years below:

                2002..................            104.438%         
                2003..................            102.958%         
                2004..................            101.479%         
                2005 and thereafter...            100.000%         
                </TABLE>                                           


On or prior to June 1, 2001, CB Richard Ellis may redeem, at any time or from
time to time, up to 35% of the aggregate principal amount of the Notes
originally issued at a redemption price equal to 108 7/8% of the principal
amount thereof, plus accrued and unpaid interest thereon, if any, to the date of
redemption, with the net cash proceeds of one or more Public Equity Offerings,
provided, however, that at least $113,750,000 in aggregate principal amount of
Notes remains outstanding immediately after giving effect to each such
redemption.

Notice of redemption will be mailed at least 30 days but not more than 60 days
prior to the redemption date to each registered owner of Notes to be redeemed at
its registered address.  Notes which are called for redemption (unless CB
Richard Ellis shall default in the payment thereof) shall cease to be entitled
to the benefits of the Indenture and shall cease to bear interest from and after
the date fixed for redemption.

The indebtedness evidenced by the Notes is, to the extent and in the manner
provided in the Indenture, expressly subordinate in right of payment to the
prior payment in full of the Senior Indebtedness, whether outstanding on the
date of the Indenture or thereafter incurred, and this Note is issued subject to
the provisions of the Indenture with respect to such subordination. The
Corporation agrees, and each Holder of a Note by accepting a Note agrees, to the
subordination and authorizes the Trustee to give it effect.

If an Event of Default (as that term is defined in the Indenture) shall occur,
the principal of all Notes and the interest accrued thereon may be declared due
and payable upon the conditions, in the manner and with the effect provided in
the Indenture. The Indenture provides that in certain events such declaration
and its consequences may be waived by the Holders of a majority in aggregate
principal amount of the Notes then Outstanding.

The Notes are issuable in registered form in denominations of $1,000 and any
integral multiple thereof.  Notes may be exchanged for a like aggregate amount
of Notes of other authorized denominations as provided in the Indenture.  This
Note is transferable at the office of the Trustee in New York, New York by the
registered owner hereof in person, or by such registered owner's attorney duly
authorized in writing, on the books of the Trustee, but only in the manner,
subject to the limitations and upon payment of the charges provided in the
Indenture, and upon surrender and cancellation of this Note.  Upon such transfer
a new fully registered Note or Notes of authorized denomination or
denominations, for the same aggregate principal amount will be issued to the
transferee in exchange herefor.

                                      -44-
<PAGE>
 
CB Richard Ellis, the Trustee and any agent of CB Richard Ellis or the Trustee
may treat the registered owner hereof as the absolute owner of this Note for the
purpose of receiving payment as herein provided and for all other purposes, and
none of CB Richard Ellis, the Trustee or any such agent shall be affected by
notice to the contrary.

THIS NOTE, THE INDENTURE AND THE OBLIGATIONS OF CB RICHARD ELLIS IN RESPECT
HEREOF AND THEREOF ARE GOVERNED BY AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK (INCLUDING WITHOUT LIMITATION, SECTION 5-1401 OF
THE NEW YORK GENERAL OBLIGATIONS LAW).

No recourse shall be had for the payment of the principal of or the interest on
this Note or for any claim based hereon, or otherwise in respect hereof, or
based on or in respect of the Indenture or any indenture supplemental thereto,
against any incorporator, stockholder, officer or director, as such, past,
present or future of CB Richard Ellis or of any successor thereof, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.
