Dear Sirs:

         BLUM CB Corp., a Delaware corporation (the "Issuer"), proposes to issue
and sell to Credit Suisse First Boston Corporation ("CSFBC"), HSBC Securities
(USA) Inc., Credit Lyonnais Securities (USA) Inc. and Scotia Capital (USA) Inc.
(the "Initial Purchasers"), upon the terms set forth in a purchase agreement of
even date herewith (the "Purchase Agreement"), $229,000,000 aggregate principal
amount of its 11 1/4% Senior Subordinated Notes Due 2011 to be guaranteed by the
CBRE Holding, Inc. (the "Parent Guarantor") on the issue date (the "Notes"). The
Notes will be issued pursuant to an Indenture, dated as of June 7, 2001 (the
"Indenture"), among the Issuer, the Parent Guarantor and State Street Bank and
Trust Company of California, N.A., as trustee (the "Trustee"). As part of the
Transactions (as defined in the Purchase Agreement), the Issuer will merge with
and into CB Richard Ellis Services, Inc., with CB Richard Ellis Services, Inc.
as the surviving corporation in such merger (the "Merger"). If the Merger and
the other Transactions are consummated on or before the 75th day after the
closing of the offering of the Notes, CB Richard Ellis Services, Inc. and its
subsidiaries that are guarantors ("Subsidiary Guarantors") under the Credit
Agreement to be entered into concurrently with the consummation of the Merger
will (1) execute counterparts to this Agreement and the Purchase Agreement,
which will cause the obligations of the Issuer under this Agreement and the
Purchase Agreement which survive past the closing date of the Merger to be
contractually assumed by CB Richard Ellis Services, Inc. and the Subsidiary
Guarantors and (2) enter into a supplemental indenture relating to the
Indenture, which will cause the obligations of the Issuer to be assumed by CB
Richard Ellis Services, Inc. and to be guaranteed on an unconditional senior
subordinated basis by the Subsidiary Guarantors (the "Subsidiary Guaranties").
If the Merger and the other Transactions are not consummated on or before the
75th day after the closing of the offering of the Notes or the Merger Agreement
(as defined in the Purchase Agreement) is terminated at any time prior thereto,
the Issuer will redeem the Notes at a redemption price equal to 100% of the
accreted value of the Notes plus accrued and unpaid interest to the date of
redemption. As used herein, the "Company" refers to the Issuer and the Parent
Guarantor before the Merger and to CB Richard Ellis Services, Inc., the Parent
Guarantor and the Subsidiary Guarantors after the Merger. The "Initial
Securities" refers to the Notes (which term includes the notes and the guaranty
by the Parent Guarantor) before the Merger and the Notes, the Parent Guaranty
and the Subsidiary Guaranties after the Merger.

         As an inducement to the Initial Purchasers to enter into the Purchase
Agreement, the Company agrees with the Initial Purchasers, for the benefit of
the holders of the Initial Securities (including, without limitation, the
Initial Purchasers), the Exchange Securities (as defined below) and the Private
Exchange Securities (as defined below) (collectively, the "Holders"), as
follows:

         1. Registered Exchange Offer. Unless not permitted by applicable law
(after the Company has complied with the ultimate paragraph of this Section 1),
the Company shall prepare and, not later than 90 days (such 90th day being a
"Filing Deadline") after the date on which the Merger is consummated (the
"Merger Date"), file with the Securities and Exchange Commission (the
"Commission") a registration statement (the "Exchange Offer Registration
Statement") on an appropriate form under the Securities Act of 1933, as amended
(the "Securities Act"), with respect to a proposed offer (the "Registered
Exchange Offer") to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the Commission
from participating in the Registered Exchange Offer, to issue and deliver to
such Holders, in exchange for the Initial Securities, a like aggregate principal
amount of debt securities of the Company issued under the Indenture, identical
in all material respects to the Initial Securities and registered under the
Securities Act (the "Exchange Securities"). The Company shall use its reasonable
best efforts to (i) cause such Exchange Offer Registration Statement to become
effective under the Securities Act within 180 days after the Merger Date (such
180th day being an "Effectiveness Deadline") and (ii) keep the Exchange Offer
Registration Statement effective for not less than 20 business days (or longer,
if required by applicable law) after the date notice of the Registered Exchange
Offer is mailed to the Holders (such period being called the "Exchange Offer
Registration Period").

         If the Company commences the Registered Exchange Offer, the Company (i)
will be entitled to consummate the Registered Exchange Offer 20 business days
after such commencement (provided that the Company has accepted all the Initial
Securities theretofore validly tendered in accordance with the terms of the
Registered Exchange Offer) and (ii) will be required to consummate the
Registered Exchange Offer no later than 40 days after the date on which the
Exchange Offer Registration Statement is declared effective (such 40th day being
the "Consummation Deadline").

         Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities electing to exchange the
Initial Securities for Exchange Securities (assuming that such Holder is not an
affiliate of the Company within the meaning of the Securities Act, acquires the
Exchange Securities in the ordinary course of such Holder's business and has no
arrangements with any person to participate in the distribution of the Exchange
Securities and is not prohibited by any law or policy of the Commission from
participating in the Registered Exchange Offer) to trade such Exchange
Securities from and after their receipt without any limitations or restrictions
under the Securities Act and without material restrictions under the securities
laws of the several states of the United States.

         The Company acknowledges that, pursuant to current interpretations by
the Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (i) each Holder which is a broker-dealer
electing to exchange Initial Securities, acquired for its own account as a
result of market making activities or other trading activities, for Exchange
Securities (an "Exchanging Dealer"), is required to deliver a prospectus
containing the information set forth in (a) Annex A hereto on the cover, (b)
Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of
the Exchange Offer" section, and (c) Annex C hereto in the "Plan of
Distribution" section of such prospectus in connection with a sale of any such
Exchange Securities received by such Exchanging Dealer pursuant to the
Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell
Securities (as defined below) acquired in exchange for Initial Securities
constituting any portion of an unsold allotment, is required to deliver a
prospectus containing the information required by Items 507 or 508 of Regulation
S-K under the Securities Act, as applicable, in connection with such sale.

         The Company shall use its reasonable best efforts to keep the Exchange
Offer Registration Statement effective and to amend and supplement the
prospectus contained therein, in order to permit such prospectus to be lawfully
delivered by all persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such persons must comply with such
requirements in order to resell the Exchange Securities; provided, however, that
                                                         --------  ------
(i) in the case where such prospectus and any amendment or supplement thereto
must be delivered by an Exchanging Dealer or an Initial Purchasers, such period
shall be the lesser of 180 days and the date on which all Exchanging Dealers and
the Initial Purchasers have sold all

                                       2
<PAGE>

Exchange Securities held by them (unless such period is extended pursuant to
Section 3(j) below) and (ii) the Company shall make such prospectus and any
amendment or supplement thereto available to any broker-dealer for use in
connection with any resale of any Exchange Securities for a period of not less
than 180 days after the consummation of the Registered Exchange Offer.
Notwithstanding the foregoing, the Company shall not be obligated to keep the
Exchange Offer Registration Statement continuously effective to the extent set
forth above if the Company determines, in its reasonable judgment, upon advice
of counsel, that the continued effectiveness and usability of the Exchange Offer
Registration Statement would (i) require the disclosure of material information,
which the Company or any of its subsidiaries has a bona fide business reason for
preserving as confidential or (ii) interfere with any existing or prospective
financing, acquisition, corporate reorganization or other material business
situation, transaction or negotiation involving the Company or any of its
subsidiaries; provided, however, that the failure to keep the Exchange Offer
              --------  -------
Registration Statement effective and usable for such reason shall last no longer
than 20 days (whereafter Additional Interest (as defined in Section 6(a)) shall
accrue and be payable until the Exchange Offer Registration Statement becomes
effective and usable) and shall in no event occur during the first 30 days after
the Exchange Offer Registration Statement becomes effective. In the event that
the Company does not keep the Exchange Offer Registration Statement continuously
effective as provided in the immediately preceding sentence, the number of days
during which the Exchange Offer Registration Statement is not continuously
effective, which shall include the date the Company gives notice that the
Exchange Offer Registration Statement is no longer effective, shall be added on
to, and therefore extend, the period during which the Company is obligated to
use its reasonable best efforts to keep the Exchange Offer Registration
Statement effective and to amend and supplement the prospectus contained
therein.

         If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and identical in all material respects to the Initial
Securities (the "Private Exchange Securities"). The Initial Securities, the
Exchange Securities and the Private Exchange Securities are herein collectively
called the "Securities".

         In connection with the Registered Exchange Offer, the Company shall:

                  (a) mail to each Holder a copy of the prospectus forming part
         of the Exchange Offer Registration Statement, together with an
         appropriate letter of transmittal and related documents;

                  (b) keep the Registered Exchange Offer open for not less than
         20 business days (or longer, if required by applicable law) after the
         date notice thereof is mailed to the Holders;

                  (c) utilize the services of a depositary for the Registered
         Exchange Offer with an address in the Borough of Manhattan, The City of
         New York, which may be the Trustee or an affiliate of the Trustee;

                  (d) permit Holders to withdraw tendered Securities at any time
         prior to the close of business, New York time, on the last business day
         on which the Registered Exchange Offer shall remain open; and

                  (e) otherwise comply with all applicable laws.

         As soon as practicable after the close of the Registered Exchange Offer
or the Private Exchange, as the case may be, the Company shall:

                  (x) accept for exchange all the Securities validly tendered
         and not withdrawn pursuant to the Registered Exchange Offer and the
         Private Exchange;

                  (y) deliver to the Trustee for cancellation all the Initial
         Securities so accepted for exchange; and

                                       3
<PAGE>

                  (z) cause the Trustee to authenticate and deliver promptly to
         each Holder of the Initial Securities, Exchange Securities or Private
         Exchange Securities, as the case may be, equal in principal amount to
         the Initial Securities of such Holder so accepted for exchange.

         The Indenture will provide that the Exchange Securities will not be
subject to the transfer restrictions set forth in the Indenture and that all the
Securities will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

         Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the date of original issue of the Initial
Securities.

         Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder
will be acquired in the ordinary course of business, (ii) such Holder will have
no arrangements or understanding with any person to participate in the
distribution of the Securities or the Exchange Securities within the meaning of
the Securities Act, (iii) such Holder is not an "affiliate," as defined in Rule
405 of the Securities Act, of the Company or if it is an affiliate, such Holder
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable, (iv) if such Holder is not a
broker-dealer, that it is not engaged in, and does not intend to engage in, the
distribution of the Exchange Securities and (v) if such Holder is a
broker-dealer, that it will receive Exchange Securities for its own account in
exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Securities.

         Notwithstanding any other provisions hereof, the Company will ensure
that (i) any Exchange Offer Registration Statement and any amendment thereto and
any prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations
thereunder, (ii) any Exchange Offer Registration Statement and any amendment
thereto does not, when it becomes effective, 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 and (iii) any prospectus
forming part of any Exchange Offer Registration Statement, and any supplement to
such prospectus, does not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

         2. Shelf Registration. If, (i) applicable interpretations of the staff
of the Commission do not permit the Company to effect a Registered Exchange
Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer
is not consummated by the 220th day after the Merger Date, (iii) any Initial
Purchaser so requests with respect to the Initial Securities (or the Private
Exchange Securities) not eligible to be exchanged for Exchange Securities in the
Registered Exchange Offer and held by it following consummation of the
Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer)
is prohibited by law or Commission policy from participating in the Registered
Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer)
that participates in the Registered Exchange Offer, such Holder does not receive
freely tradeable Exchange Securities on the date of the exchange and any such
Holder so requests, the Company shall take the following actions (the date on
which any of the conditions described in the foregoing clauses (i) through (iv)
occur, including in the case of clauses (iii) or (iv) the receipt of the
required notice, being a "Trigger Date"):

                  (a) The Company shall as promptly as practicable (but in no
         event more than 90 days after the Trigger Date (such 90th day being a
         "Filing Deadline")) file with the Commission and thereafter use its
         reasonable best efforts to cause to be declared effective: in the case
         of clause (i), no later than 180 days after the Merger Date and, in the
         case of clauses (ii) through (iv), no later than 90th date after the
         Trigger Date (such 180th day after the Merger Date in the case of
         clause (i), or such 90th day after the Trigger Date in the case of
         clauses (ii) through (iv) being an "Effectiveness Deadline") a
         registration statement (the "Shelf Registration Statement" and,
         together with the Exchange Offer Registration Statement, a
         "Registration Statement") on an appropriate form under the Securities
         Act relating to the offer and sale of the Transfer Restricted

                                       4
<PAGE>

         Securities by the Holders thereof from time to time in accordance with
         the methods of distribution set forth in the Shelf Registration
         Statement and Rule 415 under the Securities Act (hereinafter, the
         "Shelf Registration"); provided, however, that no Holder (other than an
                                --------  -------
         Initial Purchaser) shall be entitled to have the Securities held by it
         covered by such Shelf Registration Statement unless such Holder agrees
         in writing to be bound by all the provisions of this Agreement
         applicable to such Holder.

                  (b) The Company shall use its reasonable best efforts to keep
         the Shelf Registration Statement continuously effective in order to
         permit the prospectus included therein to be lawfully delivered by the
         Holders of the relevant Securities, for a period of two years (or for
         such longer period if extended pursuant to Section 3(j) below) from the
         date of its effectiveness or such shorter period that will terminate
         when all the Securities covered by the Shelf Registration Statement (i)
         have been sold pursuant thereto or (ii) are no longer restricted
         securities (as defined in Rule 144 under the Securities Act, or any
         successor rule thereof) provided, however, the Company shall not be
                                 --------  -------
         obligated to keep the Shelf Registration Statement continuously
         effective to the extent set forth below if (i) the Company determines,
         in its reasonable judgment, upon advice of counsel, that the continued
         effectiveness and usability of the Shelf Registration statement would
         (x) require the disclosure of material information, which the Company
         or any of its subsidiaries has a bona fide business reason for
         preserving as confidential or (y) interfere with any financing,
         acquisition, corporate reorganization or other material transaction
         involving the Company or any of its subsidiaries, provided that the
                                                           --------
         failure to keep the Shelf Registration Statement effective and usable
         for offers and sales of Securities for the reasons set forth in clauses
         (x) and (y) above shall last no longer than 60 days in any 12- month
         period (whereafter Additional Interest (as defined in Section 6(a))
         shall accrue and be payable until the Shelf Registration Statement
         becomes effective and usable) and (ii) the Company promptly thereafter
         complies with the requirements of Section 3(j) hereof, if applicable;
         provided, further, that the number of days of any actual Suspension
         --------  -------
         Period (as hereinafter defined) shall be added on to, and therefore
         extend, the two-year period specified above. Any such period during
         which the Company is excused from keeping the Shelf Registration
         Statement effective and usable for offers and sales of securities is
         referred to herein as a "Suspension Period." A Suspension Period shall
         commence on and include the date that the Company gives notice that the
         Shelf Registration Statement is no longer effective or the prospectus
         included therein is no longer usable for offers and sales of Securities
         and shall end on the earlier to occur of (1) the date on which each
         seller of Securities covered by the Shelf Registration Statement either
         receives the copies of the supplemented or amended prospectus
         contemplated by Section 3(j) hereof or is advised in writing by the
         Company that the use of the prospectus may be resumed and (2) the
         expiration of 60 days in any 12-month period during which one or more
         Suspension Periods has been in effect. The Company shall be deemed not
         to have used its reasonable best efforts to keep the Shelf Registration
         Statement effective during the requisite period if it voluntarily takes
         any action that would result in Holders of Securities covered thereby
         not being able to offer and sell such Securities during that period,
         unless such action is (A) required by applicable law or (B) permitted
         by this paragraph.

                  (c) Notwithstanding any other provisions of this Agreement to
         the contrary, the Company shall cause the Shelf Registration Statement
         and the related prospectus and any amendment or supplement thereto, as
         of the effective date of the Shelf Registration Statement, amendment or
         supplement, (i) to comply in all material respects with the applicable
         requirements of the Securities Act and the rules and regulations of the
         Commission and (ii) not to contain any untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary in order to make the statements therein, in light of the
         circumstances under which they were made, not misleading.

         3.  Registration Procedures. In connection with any Shelf Registration
contemplated by Section 2 hereof and, to the extent applicable, any Registered
Exchange Offer contemplated by Section 1 hereof, the following provisions shall
apply:

                  (a) The Company shall (i) furnish to each Initial Purchaser,
         prior to the filing thereof with the Commission, a copy of the
         Registration Statement and each amendment thereof and each supplement,
         if any, to the prospectus included therein and, in the event that an
         Initial Purchaser (with respect to any portion of an unsold allotment
         from the original offering) is participating in the Registered Exchange
         Offer or the Shelf Registration Statement, the Company shall use its

                                       5
<PAGE>

         reasonable best efforts to reflect in each such document, when so filed
         with the Commission, such comments as such Initial Purchaser reasonably
         may propose; (ii) include the information set forth in Annex A hereto
         on the cover, in Annex B hereto in the "Exchange Offer Procedures"
         section and the "Purpose of the Exchange Offer" section and in Annex C
         hereto in the "Plan of Distribution" section of the prospectus forming
         a part of the Exchange Offer Registration Statement and include the
         information set forth in Annex D hereto in the Letter of Transmittal
         delivered pursuant to the Registered Exchange Offer; (iii) if requested
         by an Initial Purchaser, include the information required by Items 507
         or 508 of Regulation S-K under the Securities Act, as applicable, in
         the prospectus forming a part of the Exchange Offer Registration
         Statement; (iv) include within the prospectus contained in the Exchange
         Offer Registration Statement a section entitled "Plan of Distribution,"
         reasonably acceptable to the Initial Purchasers, which shall contain a
         summary statement of the positions taken or policies made by the staff
         of the Commission with respect to the potential "underwriter" status of
         any broker-dealer that is the beneficial owner (as defined in Rule 13d-
         3 under the Securities Exchange Act of 1934, as amended (the "Exchange
         Act")) of Exchange Securities received by such broker-dealer in the
         Registered Exchange Offer (a "Participating Broker-Dealer"), whether
         such positions or policies have been publicly disseminated by the staff
         of the Commission or such positions or policies, in the reasonable
         judgment of the Initial Purchasers based upon advice of counsel (which
         may be in-house counsel), represent the prevailing views of the staff
         of the Commission; and (v) in the case of a Shelf Registration
         Statement, include the names of the Holders who propose to sell
         Securities pursuant to the Shelf Registration Statement as selling
         securityholders.

                  (b) The Company shall give written notice to the Initial
         Purchasers, the Holders of the Securities and any Participating
         Broker-Dealer from whom the Company has received prior written notice
         that it will be a Participating Broker-Dealer in the Registered
         Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall
         be accompanied by an instruction to suspend the use of the prospectus
         until the requisite changes have been made):

                           (i)   when the Registration Statement or any
                  amendment thereto has been filed with the Commission and when
                  the Registration Statement or any post-effective amendment
                  thereto has become effective;

                           (ii)  of any request by the Commission for amendments
                  or supplements to the Registration Statement or the prospectus
                  included therein or for additional information;

                           (iii) of the issuance by the Commission of any stop
                  order suspending the effectiveness of the Registration
                  Statement or the initiation of any proceedings for that
                  purpose;

                           (iv)  of the receipt by the Company or its legal
                  counsel of any notification with respect to the suspension of
                  the qualification of the Securities for sale in any
                  jurisdiction or the initiation or threatening of any
                  proceeding for such purpose; and

                           (v)   of the happening of any event that requires the
                  Company to make changes in the Registration Statement or the
                  prospectus in order that the Registration Statement or the
                  prospectus do not contain an untrue statement of a material
                  fact nor omit to state a material fact required to be stated
                  therein or necessary to make the statements therein (in the
                  case of the prospectus, in light of the circumstances under
                  which they were made) not misleading.

                  (c) The Company shall make every reasonable effort to obtain
         the withdrawal at the earliest possible time, of any order suspending
         the effectiveness of the Registration Statement.

                  (e) The Company shall deliver to each Exchanging Dealer and
         each Initial Purchaser, and to any other Holder who so requests,
         without charge, at least one copy of the Exchange Offer Registration
         Statement and any post-effective amendment thereto, including financial
         statements and schedules, and, if any Initial Purchaser or any such
         Holder requests, all exhibits thereto (including those incorporated by
         reference).

                  (f) The Company shall, during the Shelf Registration Period,
         deliver to each Holder of Securities included within the coverage of
         the Shelf Registration, without charge, as many copies of the
         prospectus (including each preliminary prospectus) included in the
         Shelf Registration Statement and any amendment or supplement thereto as
         such person may reasonably request. The Company consents, subject to
         the provisions of this Agreement, to the use of the prospectus or any
         amendment or supplement thereto by each of the selling Holders of the
         Securities in connection with the offering and sale of the Securities
         covered by the prospectus, or any amendment or supplement thereto,
         included in the Shelf Registration Statement.

                  (g) The Company shall deliver to each Initial Purchaser, any
         Exchanging Dealer, any Participating Broker-Dealer and such other
         persons required to deliver a prospectus following the Registered
         Exchange Offer, without charge, as many copies of the final prospectus
         included in the Exchange Offer Registration Statement and any amendment
         or supplement thereto as such persons may reasonably request. The
         Company consents, subject to the provisions of this Agreement, to the
         use of the prospectus or any amendment or supplement thereto by any
         Initial Purchaser, if necessary, any Participating Broker-Dealer and
         such other persons required to deliver a prospectus following the
         Registered Exchange Offer in connection with the offering and sale of
         the Exchange Securities covered by the prospectus, or any amendment or
         supplement thereto, included in such Exchange Offer Registration
         Statement.

                  (h) Prior to any public offering of the Securities pursuant to
         any Registration Statement the Company shall use its reasonable best
         efforts to register or qualify or cooperate with the Holders of the
         Securities included therein and their respective counsel in connection
         with the registration or qualification of the Securities for offer and
         sale under the securities or "blue sky" laws of such states of the
         United States as any Holder of the Securities reasonably requests in
         writing and do any and all other acts or things necessary or advisable
         to enable the offer and sale in such jurisdictions of the Securities
         covered by such Registration Statement; provided, however, that the
         Company shall not be required to (i) qualify generally to do business
         in any jurisdiction where it is not then so qualified or (ii) take any
         action which would subject it to general service of process or to
         taxation in any jurisdiction where it is not then so subject.

                  (i) The Company shall cooperate with the Holders of the
         Securities to facilitate the timely preparation and delivery of
         certificates representing the Securities to be sold pursuant to any
         Registration Statement free of any restrictive legends and in such
         denominations and registered in such names as the Holders may request a
         reasonable period of time prior to sales of the Securities pursuant to
         such Registration Statement.

                  (j) Upon the occurrence of any event contemplated by
         paragraphs (ii) through (v) of Section 3(b) above during the period for
         which the Company is required to maintain an effective Registration
         Statement, the Company shall promptly prepare and file a post-effective
         amendment to the Registration Statement or a supplement to the related
         prospectus and any other required document so that, as thereafter
         delivered to Holders of the Securities or purchasers of Securities, the
         prospectus will not contain an untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading. If the Company notifies the
         Initial Purchasers, the Holders of the Securities and any known
         Participating Broker-Dealer in accordance with paragraphs (ii) through
         (v) of Section 3(b) above to suspend the use of the prospectus until
         the requisite changes to the prospectus have been made, then the
         Initial Purchasers, the Holders of the Securities and any such
         Participating Broker-Dealers shall suspend use of such prospectus, and
         the period of effectiveness of the Shelf Registration Statement
         provided for in Section 2(b) above and the Exchange Offer Registration
         Statement provided for in Section 1 above shall each be extended by the
         number of days from and including the date of the giving of such notice
         to and including the date when the Initial Purchasers, the Holders of
         the Securities and any known Participating

                                       7
<PAGE>

         Broker-Dealer shall have received such amended or supplemented
         prospectus pursuant to this Section 3(j).

                  (k) Not later than the effective date of the applicable
         Registration Statement, the Company will provide a CUSIP number for the
         Initial Securities, the Exchange Securities or the Private Exchange
         Securities, as the case may be, and provide the applicable trustee with
         printed certificates for the Initial Securities, the Exchange
         Securities or the Private Exchange Securities, as the case may be, in a
         form eligible for deposit with The Depository Trust Company.

                  (l) The Company will comply with all rules and regulations of
         the Commission to the extent and so long as they are applicable to the
         Registered Exchange Offer or the Shelf Registration and will make
         generally available to its security holders (or otherwise provide in
         accordance with Section 11(a) of the Securities Act) an earnings
         statement satisfying the provisions of Section 11(a) of the Securities
         Act, no later than 45 days after the end of a 12-month period (or 90
         days, if such period is a fiscal year) beginning with the first month
         of the Company's first fiscal quarter commencing after the effective
         date of the Registration Statement, which statement shall cover such
         12-month period.

                  (m) The Company shall cause the Indenture to be qualified
         under the Trust Indenture Act of 1939, as amended, in a timely manner
         and containing such changes, if any, as shall be necessary for such
         qualification. In the event that such qualification would require the
         appointment of a new trustee under the Indenture, the Company shall
         appoint a new trustee thereunder pursuant to the applicable provisions
         of the Indenture.

                  (n) The Company may require each Holder of Securities to be
         sold pursuant to the Shelf Registration Statement to furnish to the
         Company such information regarding the Holder and the distribution of
         the Securities as the Company may from time to time reasonably require
         for inclusion in the Shelf Registration Statement, and the Company may
         exclude from such registration the Securities of any Holder that
         unreasonably fails to furnish such information within a reasonable time
         after receiving such request.

                  (o) The Company shall enter into such customary agreements
         (including, if requested by the Holders of at least 10% of the
         aggregate principal amount of the outstanding Securities covered
         thereby, an underwriting agreement in customary form) and take all such
         other action, if any, as the Holders of at least 10% of the aggregate
         principal amount of the outstanding Securities shall reasonably request
         in order to facilitate the disposition of the Securities pursuant to
         any Shelf Registration.

                  (p) In the case of any Shelf Registration, the Company shall
         (i) make reasonably available for inspection by the Holders of the
         Securities, any underwriter participating in any disposition pursuant
         to the Shelf Registration Statement and any attorney, accountant or
         other agent retained by the Holders of the Securities or any such
         underwriter all relevant financial and other records, pertinent
         corporate documents and properties of the Company and (ii) cause the
         Company's officers, directors, employees, accountants and auditors to
         supply all relevant information reasonably requested by the Holders of
         the Securities or any such underwriter, attorney, accountant or agent
         in connection with the Shelf Registration Statement (the information
         supplied pursuant to clauses (i) and (ii) being the "Records"), in each
         case, as shall be reasonably necessary to enable such persons, to
         conduct a reasonable investigation within the meaning of Section 11 of
         the Securities Act; provided, however, that any such person shall first
                             --------  -------
         agree in writing with the Company that any information that is
         reasonably and in good faith designated by the Company as confidential
         at the time of delivery of such information shall be kept confidential
         by such person, unless (A) disclosure of such information is required
         by court or administrative order or is necessary to respond to
         inquiries of regulatory authorities, (B) disclosure of such information
         is required by law (including any disclosure requirements pursuant to
         federal securities laws in connection with the filing of the
         Registration Statement or the use of any prospectus) or (C) such
         information becomes generally available to the public other than as a
         result of a disclosure or failure to safeguard such information by such
         person; provided further that the foregoing inspection and information
                 --------  -------
         gathering shall be coordinated on behalf of the Initial Purchasers by
         CSFBC and on behalf of the other parties, by one counsel designated by
         and on behalf of such other parties as described in Section 4 hereof.
         Each Holder of Securities and the Initial Purchasers further agree

                                       8
<PAGE>

         and shall cause any person reviewing documents on their behalf pursuant
         to this paragraph (p) to agree, that it will, upon learning that
         disclosure of such Records is sought pursuant to clause (A) or (B)
         above, give notice to the Company and allow the Company, at its
         expense, to undertake appropriate action to prevent disclosure of the
         Records deemed confidential.

                  (q) In the case of any Shelf Registration, the Company, if
         requested by any Holder of at least 10% of the aggregate principal
         amount of the outstanding Securities covered thereby, shall cause (i)
         its counsel to deliver an opinion and updates thereof relating to the
         Securities in customary form addressed to such Holders and the managing
         underwriters, if any, thereof and dated, in the case of the initial
         opinion, the effective date of such Shelf Registration Statement (it
         being agreed that the matters to be covered by such opinion shall
         include, without limitation, the due incorporation and good standing of
         the Company and the Subsidiary Guarantors); the qualification of the
         Company and the Subsidiary Guarantors to transact business as foreign
         corporations; the due authorization, execution and delivery of the
         relevant agreement of the type referred to in Section 3(o) hereof; the
         due authorization, execution, authentication and issuance, and the
         validity and enforceability, of the applicable Securities; the absence
         of material legal or governmental proceedings involving the Company and
         the Subsidiary Guarantors; the absence of governmental approvals
         required to be obtained in connection with the Shelf Registration
         Statement, the offering and sale of the applicable Securities, or any
         agreement of the type referred to in Section 3(o) hereof; the
         compliance as to form of such Shelf Registration Statement and any
         documents incorporated by reference therein and of the Indenture with
         the requirements of the Securities Act and the Trust Indenture Act,
         respectively; and, as of the date of the opinion and as of the
         effective date of the Shelf Registration Statement or most recent
         post-effective amendment thereto (or in the case of a Shelf
         Registration Statement where a new Annual Report on Form 10-K has been
         filed by the Company subsequent to the effective date of the Shelf
         Registration Statement or latest post-effective amendment thereto, as
         of the date of such Annual Report), as the case may be, the absence
         from such Shelf Registration Statement and the prospectus included
         therein, as then amended or supplemented, and from any documents
         incorporated by reference therein of an untrue statement of a material
         fact or the omission to state therein a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading (in the case of any such documents, in the light of the
         circumstances existing at the time that such documents were filed with
         the Commission under the Exchange Act); (ii) its officers to execute
         and deliver all customary documents and certificates and updates
         thereof requested by any underwriters of the applicable Securities and
         (iii) its independent public accountants to provide to the selling
         Holders of the applicable Securities and any underwriter therefor a
         comfort letter in customary form and covering matters of the type
         customarily covered in comfort letters in connection with primary
         underwritten offerings, subject to receipt of appropriate documentation
         as contemplated, and only if permitted, by Statement of Auditing
         Standards No. 72.

                  (r) In the case of the Registered Exchange Offer, if requested
         by any Initial Purchaser or any known Participating Broker-Dealer, the
         Company shall cause (i) its counsel to deliver to such Initial
         Purchaser or such Participating Broker-Dealer a signed opinion
         substantially in the form set forth in Exhibits A and C to the Purchase
         Agreement, modified as is customary in connection with the preparation
         of a Registration Statement and (ii) its independent public accountants
         to deliver to such Initial Purchaser or such Participating
         Broker-Dealer a comfort letter, in customary form, meeting the
         requirements as to the substance thereof as set forth in Section 6(a)
         of the Purchase Agreement, with appropriate date changes.

                  (s) If a Registered Exchange Offer or a Private Exchange is to
         be consummated, upon delivery of the Initial Securities by Holders to
         the Company (or to such other Person as directed by the Company) in
         exchange for the Exchange Securities or the Private Exchange
         Securities, as the case may be, the Company shall mark, or caused to be
         marked, on the Initial Securities so exchanged that such Initial
         Securities are being canceled in exchange for the Exchange Securities
         or the Private Exchange Securities, as the case may be; in no event
         shall the Initial Securities be marked as paid or otherwise satisfied.

                  (t) If the Initial Securities have been rated prior to the
         initial sale of such Initial Securities, the Company will use its
         reasonable best efforts to confirm such ratings will apply to the
         Securities covered by a Registration Statement.

         of an underwriting syndicate or selling group or "assist in the
         distribution" (within the meaning of the Conduct Rules (the "Rules") of
         the National Association of Securities Dealers, Inc. ("NASD")) thereof,
         whether as a Holder of such Securities or as an underwriter, a
         placement or sales agent or a broker or dealer in respect thereof, or
         otherwise, the Company will assist such broker-dealer in complying with
         the requirements of such Rules, including, without limitation, by (i)
         if such Rules, including Rule 2720, shall so require, engaging a
         "qualified independent underwriter" (as defined in Rule 2720) to
         participate in the preparation of the Registration Statement relating
         to such Securities, to exercise usual standards of due diligence in
         respect thereto and, if any portion of the offering contemplated by
         such Registration Statement is an underwritten offering or is made
         through a placement or sales agent, to recommend the yield of such
         Securities, (ii) indemnifying any such qualified independent
         underwriter to the extent of the indemnification of underwriters
         provided in Section 5 hereof and (iii) providing such information to
         such broker-dealer as may be required in order for such broker-dealer
         to comply with the requirements of the Rules.

                  (v) The Company shall use its reasonable best efforts to take

harmless each Holder of the Securities, any Participating Broker-Dealer and each
person, if any, who controls such Holder or such Participating Broker-Dealer

collectively as the "Indemnified Parties") from and against any losses, claims,

                                       10
<PAGE>

respect thereof (including, but not limited to, any losses, claims, damages,
liabilities or actions relating to purchases and sales of the Securities) to
which each Indemnified Party may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities
or actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in a Registration Statement or prospectus
or in any amendment or supplement thereto or in any preliminary prospectus
relating to a Shelf Registration, or arise out of, or are based upon, the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
shall reimburse, as incurred, the Indemnified Parties for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action in respect thereof;
provided, however, that (i) the Company shall not be liable in any such case to
--------  -------
the extent that such loss, claim, damage or liability arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission (A) made in a Registration Statement or prospectus or in any amendment
or supplement thereto or in any preliminary prospectus relating to a Shelf
Registration in reliance upon and in conformity with written information
pertaining to such Holder and furnished to the Company by or on behalf of such
Holder specifically for inclusion therein or (B) resulting from the use of the
prospectus during the period when the use of the prospectus was suspended or
otherwise unavailable for sales thereunder in accordance with the terms of this
Agreement; provided, however, that Holders received at least 10 days prior
           --------  -------
written notice of such suspension or other unavailability; and (ii) with respect
to any untrue statement or omission or alleged untrue statement or omission made
in any preliminary prospectus relating to a Shelf Registration Statement, the
indemnity agreement contained in this subsection (a) shall not inure to the
benefit of any Holder or Participating Broker-Dealer from whom the person
asserting any such losses, claims, damages or liabilities purchased the
Securities concerned, to the extent that a prospectus relating to such
Securities was required to be delivered by such Holder or Participating Broker-
Dealer under the Securities Act in connection with such purchase and any such
loss, claim, damage or liability of such Holder or Participating Broker-Dealer
results from the fact that there was not sent or given to such person, at or
prior to the written confirmation of the sale of such Securities to such person,
a copy of the final prospectus if the Company had previously furnished copies
thereof to such Holder or Participating Broker-Dealer; provided further,
                                                       -------- --------
however, that this indemnity agreement will be in addition to any liability
-------
which the Company may otherwise have to such Indemnified Party. The Company
shall also indemnify underwriters, their officers and directors and each person
who controls such underwriters within the meaning of the Securities Act or the
Exchange Act to the same extent as provided above with respect to the
indemnification of the Holders of the Securities if requested by such Holders.

         (b) Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless the Company and each person, if any, who controls
the Company within the meaning of the Securities Act or the Exchange Act from
and against any losses, claims, damages or liabilities or any actions in respect
thereof, to which the Company or any such controlling person may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the statements therein not misleading, but in
each case only to the extent that the untrue statement or omission or alleged
untrue statement or omission was made in reliance upon and in conformity with
written information pertaining to such Holder and furnished to the Company by or
on behalf of such Holder specifically for inclusion therein; and, subject to the
limitation set forth immediately preceding this clause, shall reimburse, as
incurred, the Company for any legal or other expenses reasonably incurred by the
Company or any such controlling person in connection with investigating or
defending any loss, claim, damage, liability or action in respect thereof. This
indemnity agreement will be in addition to any liability which such Holder may
otherwise have to the Company or any of its controlling persons.

         (c) Promptly after receipt by an indemnified party under this Section 5
of notice of the commencement of any action or proceeding (including a
governmental investigation), such indemnified party will, if a claim in respect
thereof is to be made against the indemnifying party under this Section 5,
notify the indemnifying party of the commencement thereof; but the omission so
to notify the indemnifying party will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b) above. In case any
such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to

                                       11
<PAGE>

such indemnified party (who shall not, except with the consent of the
indemnified party, be counsel to the indemnifying party), and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof the indemnifying party will not be liable to such
indemnified party under this Section 5 for any legal or other expenses, other
than reasonable costs of investigation, subsequently incurred by such
indemnified party in connection with the defense thereof. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened action in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party unless such settlement includes an
unconditional release of such indemnified party from all liability on any claims
that are the subject matter of such action, and does not include a statement as
to or an admission of fault, culpability or a failure to act by or on behalf of
any indemnified party.

         (d) If the indemnification provided for in this Section 5 is
unavailable or insufficient to hold harmless an indemnified party under
subsections (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to in
subsection (a) or (b) above (i) in such proportion as is appropriate to reflect
the relative benefits received by the indemnifying party or parties on the one
hand and the indemnified party on the other from the exchange of the Securities,
pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by
the foregoing 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 indemnifying party or
parties on the one hand and the indemnified party on the other in connection
with the statements or omissions that resulted in such losses, claims, damages
or liabilities (or actions in respect thereof) as well as any other relevant
equitable considerations. The relative fault of the parties shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company on the one hand or
such Holder or such other indemnified party, as the case may be, on the other,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The amount paid by
an indemnified party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this subsection (d) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any action or claim which is
the subject of this subsection (d). Notwithstanding any other provision of this
Section 5(d), the Holders of the Securities shall not be required to contribute
any amount in excess of the amount by which the net proceeds received by such
Holders from the sale of the Securities pursuant to a Registration Statement
exceeds the amount of damages which such Holders have otherwise been required to
pay by reason of 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 Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. For purposes
of this paragraph (d), each person, if any, who controls such indemnified party
within the meaning of the Securities Act or the Exchange Act shall have the same
rights to contribution as such indemnified party and each person, if any, who
controls the Company within the meaning of the Securities Act or the Exchange
Act shall have the same rights to contribution as the Company.

         (e) The agreements contained in this Section 5 shall survive the sale
of the Securities pursuant to a Registration Statement and shall remain in full
force and effect, regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of any indemnified party.

         6.  Additional Interest Under Certain Circumstances. (a) Additional
interest (the "Additional Interest") with respect to the Securities shall be
assessed as follows if any of the following events occur (each such event in
clauses (i) through (iv) below being herein called a "Registration Default"):

         (i)   any Registration Statement required by this Agreement is not
               filed with the Commission on or prior to the applicable Filing
               Deadline;

         (ii)  any Registration Statement required by this Agreement is not
               declared effective by the Commission on or prior to the
               applicable Effectiveness Deadline;

         (iii) the Registered Exchange Offer has not been consummated on or
               prior to the Consummation Deadline; or

                                       12
<PAGE>

         (iv)  any Registration Statement required by this Agreement has been
               declared effective by the Commission but (A) such Registration
               Statement thereafter ceases to be effective or (B) such
               Registration Statement or the related prospectus ceases to be
               usable in connection with resales of Transfer Restricted
               Securities during the periods specified herein because either (1)
               any event occurs as a result of which the related prospectus
               forming part of such Registration Statement would include any
               untrue statement of a material fact or omit to state any material
               fact necessary to make the statements therein in the light of the
               circumstances under which they were made not misleading, or (2)
               it shall be necessary to amend such Registration Statement or
               supplement the related prospectus, to comply with the Securities
               Act or the Exchange Act or the respective rules thereunder.

Each of the foregoing will constitute a Registration Default whatever the reason
for any such event and whether it is voluntary or involuntary or is beyond the
control of the Company or pursuant to operation of law or as a result of any
action or inaction by the Commission.

         Additional Interest shall accrue on the Securities over and above the
interest set forth in the title of the Securities from and including the date on
which any such Registration Default shall occur to but excluding the date on
which all such Registration Defaults have been cured, at a rate of 0.50% per
annum (the "Additional Interest Rate") for the first 90-day period immediately
following the occurrence of such Registration Default. The Additional Interest
Rate shall increase by an additional 0.50% per annum with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum Additional Interest Rate of 2.0% per annum.

         (b) A Registration Default referred to in Section 6(a)(iv) hereof shall
be deemed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Holders to use the related prospectus or (y) other material events, with respect
to the Company that would need to be described in such Shelf Registration
Statement or the related prospectus and (ii) in the case of clause (y), the
Company is proceeding promptly and in good faith to amend or supplement such
Shelf Registration Statement and related prospectus to describe such events;
provided, however, that in any case if such Registration Default occurs for a
--------  -------
continuous period in excess of 30 days, Additional Interest shall be payable in
accordance with the above paragraph from the day such Registration Default
occurs until such Registration Default is cured.

         (c) Any amounts of Additional Interest due pursuant to Section 6(a)
will be payable in cash on the regular interest payment dates with respect to
the Securities. The amount of Additional Interest will be determined by
multiplying the applicable Additional Interest Rate by the principal amount of
the Securities and further multiplied by a fraction, the numerator of which is
the number of days such Additional Interest Rate was applicable during such
period (determined on the basis of a 360-day year comprised of twelve 30-day
months), and the denominator of which is 360.

         (d) "Transfer Restricted Securities" means each Security until (i) the
date on which such Security has been exchanged by a person other than a
broker-dealer for a freely transferable Exchange Security in the Registered
Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered
Exchange Offer of an Initial Security for an Exchange Note, the date on which
such Exchange Note is sold to a purchaser who receives from such broker-dealer
on or prior to the date of such sale a copy of the prospectus contained in the
Exchange Offer Registration Statement, (iii) the date on which such Security has
been effectively registered under the Securities Act and disposed of in
accordance with the Shelf Registration Statement or (iv) the date on which such
Security is distributed to the public pursuant to Rule 144 under the Securities
Act or is saleable pursuant to Rule 144(k) under the Securities Act.

         7. Rules 144 and 144A. The Company shall use its best efforts to file
the reports required to be filed by it under the Securities Act and the Exchange
Act in a timely manner and, if at any time the Company is not required to file
such reports, it will, upon the request of any Holder of Securities, make
publicly available other information so long as necessary to permit sales of
their Securities pursuant to Rules 144 and 144A. The Company covenants that it
will take such further action as any Holder of Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Securities without registration under the Securities Act within the
limitation of the exemptions provided by Rules 144

                                       13
<PAGE>

and 144A (including the requirements of Rule 144A(d)(4)). The Company will
provide a copy of this Agreement to prospective purchasers of Initial Securities
identified to the Company by the Initial Purchasers upon request. Upon the
request of any Holder of Initial Securities, the Company shall deliver to such
Holder a written statement as to whether it has complied with such requirements.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company to register any of its Securities pursuant to the Exchange
Act.

         8. Underwritten Registrations. If any of the Transfer Restricted
Securities covered by any Shelf Registration are to be sold in an underwritten
offering, the investment banker or investment bankers and manager or managers
that will administer the offering ("Managing Underwriters") will be selected by
the Holders of a majority in aggregate principal amount of such Transfer
Restricted Securities to be included in such offering and shall be reasonably
acceptable to the Company.

         No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

         9.  Miscellaneous.

         (a) Remedies. The Company acknowledges and agrees that any failure by
the Company to comply with its obligations under Section 1 and 2 hereof may
result in material irreparable injury to the Initial Purchasers or the Holders
for which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Sections 1 and
2 hereof. The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

         (b) No Inconsistent Agreements. The Company will not on or after the
date of this Agreement enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company's securities under any
agreement in effect on the date hereof.

         (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, except by the Company and the written
consent of the Holders of a majority in principal amount of the Securities
affected by such amendment, modification, supplement, waiver or consents.

         (d) Notices. All notices and other communications provided for or

         (k) Securities Held by the Company. Whenever the consent or approval of
Holders of a specified percentage of principal amount of Securities is required
hereunder, Securities held by the Company or its affiliates (other than
subsequent Holders of Securities if such subsequent Holders are deemed to be
affiliates solely by reason of their holdings of such Securities) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

         Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. The Letter
of Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of Exchange Securities received in exchange for Initial Securities
where such Initial Securities were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Company has agreed
that, for a period of 180 days after the Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See "Plan of Distribution."

         Each broker-dealer that receives Exchange Securities for its own
account in exchange for Initial Securities, where such Initial Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Securities. See "Plan of
Distribution."

                             PLAN OF DISTRIBUTION


         Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Initial Securities where such Initial Securities were acquired as a
result of market-making activities or other trading activities. The Company has
agreed that, for a period of 180 days after the Expiration Date, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for
use in connection with any such resale. In addition, until             , [   ],
all dealers effecting transactions in the Exchange Securities may be required to
deliver a prospectus./(1)/

         The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers. Exchange Securities received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities. Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that, by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

         For a period of 180 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
