                  INDENTURE SUPPLEMENT NO. 9 ("Indenture Supplement"), dated as
of January 11, 2002, between CENTEX CORPORATION, a Nevada corporation (together
with its successors and assigns as provided in the Indenture referred to below,
the "Company"), and JPMORGAN CHASE BANK, a New York banking corporation
(formerly, The Chase Manhattan Bank, successor to Chase Bank of Texas, National
Association) (together with its successors in trust thereunder as provided in
the Indenture referred to below, the "Trustee"), as trustee under an Indenture
dated as of October 1, 1998 (the "Indenture").

                              PRELIMINARY STATEMENT

                  Section 2.02 of the Indenture provides, among other things,
that the Company may, when authorized by its Board of Directors, and the Trustee
may at any time and from time to time, enter into a series supplement to the
Indenture for the purpose of authorizing one or more Series of Senior Debt
Securities and to specify certain terms of each such Series of Senior Debt
Securities. The Board of Directors of the Company has duly authorized the
creation of a Series of Senior Debt Securities to be known as the Company's
7 1/2% Notes due 2012 (the "Notes"), and the Company and the Trustee are
executing and delivering this Indenture Supplement in order to provide for the
issuance of the Notes.

                                   ARTICLE ONE

                                   Definitions

                  Except to the extent such terms are otherwise defined in this
Indenture Supplement or the context clearly requires otherwise, all terms used
in this Indenture Supplement which are defined in the Indenture or the form of
Note attached hereto as Exhibit A, either directly or by reference therein,
shall have the meanings assigned to them therein.

                  As used in this Indenture Supplement, the following terms

an installment of interest on the Notes.

MATURITY DATE:

                  The term "Maturity Date," when used with respect to any Note,

call for redemption or otherwise.

<PAGE>

STATED MATURITY:

                  The term "Stated Maturity" means, when used with respect to
any Note or any installment of interest thereon (including defaulted interest),
the date specified in such Note as the fixed date upon which the principal of
such Note or such installment of interest is due and payable.

                                   ARTICLE TWO

                         Terms and Issuance of the Notes

                  Section 2.01. Issuance and Designation. A Series of Senior
Debt Securities which shall be designated as the Company's "7 1/2% Notes due
2012" shall be executed, authenticated and delivered in accordance with the
provisions of, and shall in all respects be subject to, the terms, conditions
and covenants of, the Indenture and this Indenture Supplement (including the
form of Note set forth in Exhibit A). The aggregate principal amount of the
Notes which may be authenticated and delivered under this Indenture Supplement
shall not, except as permitted by the provisions of the Indenture, exceed
$350,000,000, provided that the Company may, without the consent of the Holders
of the Notes, reopen this Series and issue additional Notes under the Indenture
and this Indenture Supplement in addition to the $350,000,000 of Notes
authorized as of the date hereof.

                  Section 2.02. Form and Other Terms of Notes; Incorporation of
Terms. The Notes shall be substantially in the form attached hereto as Exhibit
A. The terms of such Notes are herein incorporated by reference and are part of
this Indenture Supplement.

                  Section 2.03. Place and Method of Payment. The place of
payment in respect of the Notes will be at the principal office or agency of the
Company in Dallas, Texas or at the office or place of business of the Trustee or
its successor in trust under the Indenture, which, at the date hereof, is
located at Chase Global Trust, 450 W. 33rd Street, 15th Floor, New York, New
York 10001. Payments in respect of principal or premium, if any, on Notes will
be made only against surrender of such Notes at such office. Payments of
interest on each Interest Payment Date with respect to each Note will be made to
the Person in whose name such Note is registered at the close of business on the
Regular Record Date immediately preceding such Interest Payment Date by U.S.
dollar check drawn on a bank in the City of New York or, for Holders of at least
$1,000,000 of Notes, by wire transfer to a dollar account maintained by the
payee with a bank in the United States; provided that a written request from
such Holder to such effect



                                       3
<PAGE>

designating such account is received by the Trustee or the Paying Agent no later
than 30 calendar days preceding such Interest Payment Date. Unless such
designation is revoked, any such designation made by such Holder with respect to
such Note payable to such Holder will remain in effect with respect to any
further interest payments with respect to such Note payable to such Holder. The
Company will pay any administrative costs imposed by banks in connection with
making interest payments by wire transfer.

                  So long as the Depositary continues to make its "Same-Day
Funds Settlement System" available to the Company, payments due on Notes
represented by a Global Security registered in the name of the Depositary or its
nominee will be made in immediately available funds to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Security
representing such Notes. The Company expects that the Depositary or its nominee,
upon receipt of any payment, will credit immediately participants' accounts with
payments in same-day funds in amounts proportionate to their respective
beneficial interests in such payments, as shown on the records of the Depositary
or its nominee. The Company also expects that payments by participants and
indirect participants to owners of beneficial interests in such Global Security
held through such Persons will be governed by standing instructions and
customary practices, as is now the case with securities registered in the name
of nominees for such customers, and will be the responsibility of such
participants and indirect participants.

                                  ARTICLE THREE

                              Additional Covenants

                  Section 3.01. Limitation on Liens. The following provisions
shall apply to the Notes:

                  (a) The Company will not itself, and will not permit any of
         its subsidiaries (other than Centex Financial Services, Inc. and its
         subsidiaries) to, issue, assume or guarantee any indebtedness for
         borrowed money ("Indebtedness") if such borrowed money is secured by a
         mortgage, pledge, security interest, lien or other encumbrance (any
         such mortgage, pledge, security interest, lien or other encumbrance
         being hereinafter in this Section 3.01 referred to as a "Lien") on or
         with respect to any of the properties or assets of the Company or any
         such subsidiary or on any shares of capital stock or other equity
         interests of any subsidiary that owns properties or assets (other than
         Centex Financial Services, Inc. and its subsidiaries), whether, in each
         case, owned at the date of this Indenture Supplement or thereafter
         acquired, unless the Company makes effective provision whereby the
         Notes are secured by such Lien equally and ratably with any and all
         other borrowed money thereby secured; provided, however, that the
         foregoing restrictions shall not be applicable to:

                           (i) any Lien existing on any of the Company's
                  properties or assets or shares of capital stock or other
                  equity interests at the date of this Indenture Supplement;



                                       4
<PAGE>

                           (ii) any Lien created by a subsidiary of the Company
                  in favor of the Company or any wholly-owned subsidiary;

                           (iii) any Lien on any property or asset of any
                  corporation or other entity (or on any accession or
                  improvement to such asset or any proceeds thereof) existing at
                  the time such corporation or other entity becomes a subsidiary
                  of the Company or is merged or consolidated with or into the
                  Company or any of its subsidiaries;

                           (iv) any Lien on any property or asset existing at
                  the time of acquisition thereof (or on any accession or
                  improvement to such property or asset or any proceeds thereof)
                  by the Company or any of its subsidiaries;

                           (v) any Lien on any property or asset (or on any
                  accession or improvement to such property or asset or any
                  proceeds thereof) securing Indebtedness incurred or assumed
                  for the purpose of financing all or any part of the cost of
                  acquiring such property or asset or the making of any
                  improvement thereof; provided that such Lien attaches to such
                  property or asset concurrently with or within 180 days after
                  the acquisition thereof or the making of such improvement;

                           (vi) any Lien incurred in connection with pollution
                  control, industrial revenue or any similar financing;

                           (vii) any Lien arising out of the refinancing,
                  extension, renewal or replacement of any of the Liens
                  permitted by any of clauses (i) through (vi) above; provided
                  that the principal amount of the Indebtedness secured by the
                  Lien being refinanced, extended, reviewed or replaced is not
                  increased and is not secured by any additional properties or
                  assets; and

                           (viii) any Lien imposed by law.

                  (b) Notwithstanding the provisions of subsection (a) of this
         Section 3.01, the Company or any of its subsidiaries may issue, assume
         or guarantee Indebtedness secured by a Lien which would otherwise be
         subject to the foregoing restrictions in an aggregate amount which,
         together with all other such secured borrowings of the Company and its
         subsidiaries and the Attributable Debt (as defined below) in respect of
         Sale and Lease-Back Transactions (as defined in Section 3.02) existing
         at such time (other than Sale and Lease-Back Transactions not subject
         to the limitation contained in Section 3.02), does not at the time
         exceed twenty percent (20%) of the Consolidated Net Tangible Assets of
         the Company and its subsidiaries, as shown on the audited consolidated
         balance sheet contained in the latest annual report to stockholders of
         the Company. The term "Attributable Debt" as used in this paragraph
         shall mean, as of any particular time, the present value of the
         obligation of a lessee for rental payments during the remaining term of
         any lease (including any period for which such lease has been extended
         or may, at the option of the lessor, be extended).

<PAGE>

                  Section 3.02. Limitation on Sale and Lease-Back Transactions.
The Company will not, nor will it permit any of its subsidiaries to, enter into
any arrangement with any Person (other than the Company) providing for the
leasing by the Company or a subsidiary of any of its properties or assets
(except for temporary leases for a term of not more than three (3) years and
except for sales and leases of model homes), which property or asset has been or
is to be sold or transferred by the Company or such subsidiary to such Person
(herein referred to as a "Sale and Lease-Back Transaction"), unless (a) the net
proceeds to the Company or such subsidiary from such sale or transfer equal or
exceed the fair value (as determined by the Board of Directors, the Chairman of
the Board, the Vice Chairman, the President or the principal financial officer
of the Company) of the property or asset so leased, (b) the Company or such
subsidiary would be entitled to incur Indebtedness secured by a Lien on the
property or asset to be leased pursuant to Section 3.01, (c) the Company shall,
and in any such case the Company covenants that it will, apply an amount equal
to the fair value (as determined by the Board of Directors, the Chairman of the
Board, the Vice Chairman, the President or the principal financial officer of
the Company) of the property or asset so leased to the retirement (other than
any mandatory retirement), within 180 days of the effective date of any such
Sale and Lease-Back Transaction, of Funded Indebtedness of the Company, (d) such
Sale and Lease-Back Transaction relates to a sale which occurred within 180 days
from the date of acquisition of such property or asset by the Company or a
subsidiary or the date of the completion of construction or commencement of full
operations on such property, whichever is later, or (e) such transaction was
consummated prior to the date of this Indenture Supplement.

                                  ARTICLE FOUR

                                   Defeasance

                  Section 4.01. Option to Effect Legal Defeasance or Covenant
Defeasance. The Company may, at any time, with respect to the Notes, elect to
have either Section 13.01 of the Indenture or Section 4.03 of this Indenture
Supplement be applied to all outstanding Notes upon compliance with the
conditions set forth in Article Thirteen of the Indenture and below in this
Article Four.

                  Section 4.02. Legal Defeasance. Upon the Company's exercise
under Section 4.01 of the option applicable to Section 13.01 of the Indenture,
the Company may terminate its obligations under the Notes, the Indenture and
this Indenture Supplement by complying with the terms and conditions of Section
13.01 of the Indenture; provided, however, that the Opinion of Counsel delivered
to the Trustee will also state that either (A) the Company has received from, or
there has been published by, the Internal Revenue Service, a ruling or (B) since
the date hereof, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such Opinion of
Counsel shall confirm that, the Holders of the outstanding Notes will not
recognize income, gain or loss for federal income tax purposes as a result of
such defeasance and will be subject to federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

<PAGE>

                  Section 4.03. Covenant Defeasance. Upon the Company's exercise
under Section 4.01 of the option applicable to this Section 4.03, the Company
shall be released from its obligations under the covenants contained in Article
Three of this Indenture Supplement with respect to the outstanding Notes on and
after the date the conditions set forth below are satisfied ("Covenant
Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, such Covenant Defeasance means that, with respect
to the outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default, but, except as
specified above, the remainder of the Indenture and such Notes shall be
unaffected thereby. In addition, the Company's exercise under Section 4.01 of
the option applicable to this Section 4.03 shall not constitute an Event of
Default.

                  Section 4.04. Conditions to Covenant Defeasance. The following
shall be the conditions to the application of Section 4.03 to the outstanding
Notes:

                  (1) the Company shall irrevocably have deposited or caused to
         be deposited with the Trustee under the terms of an irrevocable trust
         agreement in form and substance satisfactory to the Trustee, as trust
         funds in trust solely for the benefit of the Holders of such Notes for
         that purpose, money or direct non-callable obligations of, or
         non-callable obligations guaranteed by, the United States of America
         for the payment of which guarantee or obligation the full faith and
         credit of the United States is pledged ("U.S. Government Obligations")
         maturing as to principal and interest in such amounts and at such times
         as are sufficient, as verified in a Certificate of a Firm of
         Independent Public Accountants, without consideration of any
         reinvestment of such interest, to pay principal of and interest on the
         outstanding Notes to maturity or redemption as the case may be,
         provided that the Trustee or any paying agent shall have been
         irrevocably instructed to apply such money or the proceeds of such U.S.
         Government Obligations to the payment of said principal and interest
         with respect to the Notes. The Company may make an irrevocable deposit
         pursuant to this Section 4.04 only if at such time the Company shall
         have delivered to the Trustee and any such paying agent an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         herein precedent to the satisfaction and discharge of this Indenture
         have been complied with and the Opinion of Counsel further states that
         the making of such deposit (i) does not contravene or violate any
         provision of any indenture, mortgage, loan agreement or other similar
         agreement known to such counsel to which the Company is a party or by
         which it or any of its property is bound, (ii) does not require
         registration by the deposit referred to above under the Investment
         Company Act of 1940, as amended, and (iii) to the effect that the
         Holders of the outstanding Notes will not recognize income, gain or
         loss for federal income tax purposes as a result of such defeasance and
         will be subject to federal income tax in the

         same amount, in the same manner and at the same times as would have
         been the case if such defeasance had not occurred.

                  (2) Notwithstanding the foregoing paragraph, the Company's
         obligations in Sections 2.06, 2.08, 5.01, 5.02, 5.05, 6.01, 8.06, 8.10,
         13.04 and 13.05 of the Indenture shall survive until the Notes are no
         longer outstanding. Thereafter, the Company's obligations in Sections
         8.06, 13.04 and 13.05 of the Indenture shall survive.

                  Centex Corporation, a corporation duly organized and existing

                            [FORM OF REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Senior Debt
Securities of the Company designated as its ___% Notes due 20__ (herein called
the "Notes"), issued and to be issued in one or more Series under an Indenture
dated as of October 1, 1998 (herein called the "Indenture") between the Company
and JPMorgan Chase Bank (f/k/a The Chase Manhattan Bank), as Trustee (herein
called the "Trustee," which term includes any successor Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto
(including the Indenture Supplement dated as of _______ ___, 2002 which
authorizes the Notes) reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Notes, and of the terms upon which the Notes
are, and are to be, authenticated and delivered.

                  All terms used in this Note which are defined in the Indenture
or in any indenture supplemental thereto but are not defined in this Note shall
have the meanings assigned to them in the Indenture or in any indenture
supplemental thereto.

                  The indebtedness evidenced by the Notes is, to the extent and
in the manner provided in the Indenture and the Indenture Supplement, senior in
right of payment to certain indebtedness of the Company.

                  Interest on this Note will be payable on the Interest Payment
Date or Interest Payment Dates as specified on the face hereof and, in either
case, on the Maturity Date. Unless otherwise specified on the face hereof,
payments on this Note with respect to any particular Interest Payment Date or
the Maturity Date will include interest accrued from and including
______________, 2002, or from and including the most recent Interest Payment
Date to which interest has been paid or duly provided for, to but excluding the
particular Interest Payment Date or the Maturity Date. Interest on this Note
will be computed and paid on the basis of a 360-day year of twelve 30-day
months.

                  If an Interest Payment Date or the Maturity Date for this Note
falls on a day that is not a business day, payment of principal, premium, if
any, and interest to be made on such day with respect to this Note will be made
on the next succeeding day that is a business day with the same force and effect
as if made on the due date, and no additional interest will be payable on the
date of payment for the period from and after the due date as a result of such
delayed payment.

                  The Notes will be redeemable, in whole or in part, from time
to time at the option of the Company, on any date (a "Redemption Date") at a
redemption price equal to the greater of (a) 100% of the principal amount of the
Notes to be redeemed and (b) the sum of the present values of the Remaining
Scheduled Payments (as hereinafter defined) of principal and interest thereon
(exclusive of interest accrued to such Redemption Date) discounted to such
Redemption Date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as hereinafter defined) plus ___
basis points, plus accrued and unpaid interest on the principal amount being
redeemed to such Redemption Date; provided, however, that installments of
interest on the Notes that are due and payable on an Interest Payment Date
falling on or prior to the relevant Redemption Date shall be payable to the
Holders of such Notes,



                                       4
<PAGE>

registered as such at the close of business on the relevant Regular Record Date
or Special Record Date, as the case may be, according to their terms and the
provisions of the Indenture.

                  "Comparable Treasury Issue" means the United States Treasury
security selected by the Independent Investment Banker (as hereinafter defined)
as having a maturity comparable to the remaining term of the Notes to be
redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the Notes.

                  "Comparable Treasury Price" means, with respect to any
Redemption Date, (1) the average of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
on the third business day preceding such Redemption Date, as set forth in the
daily statistical release (or any successor release) published by the Federal
Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (2) if such release (or any successor release) is not
published or does not contain such prices on such business day, (A) the average
of the Reference Treasury Dealer Quotations (as hereinafter defined) for such
Redemption Date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (B) if the Trustee obtains fewer than four such Reference
Treasury Dealer Quotations, the average of all such Quotations.

                  "Independent Investment Banker" means J.P. Morgan Securities
Inc. or Salomon Smith Barney Inc.

                  "Reference Treasury Dealer" means J.P. Morgan Securities Inc.
or Salomon Smith Barney Inc. and their respective successors and, at the option
of the Company, other primary U.S. government securities dealers in New York
City selected by the Company.

                  "Reference Treasury Dealer Quotations" means, with respect to
the Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third business day preceding such Redemption Date.

                  "Remaining Scheduled Payments" means, with respect to any
Note, the remaining scheduled payments of the principal thereof to be redeemed
and interest thereon that would be due after the related Redemption Date but for
such redemption; provided, however, that, if such Redemption Date is not an
Interest Payment Date with respect to such Note, the amount of the next
succeeding scheduled interest payment thereon will be reduced by the amount of
interest accrued thereon to such Redemption Date.

                  "Treasury Rate" means, with respect to any Redemption Date for
the Notes, the rate per annum equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such Redemption Date.

                  Notice of any redemption by the Company will be mailed at
least 30 days but not more than 60 days before any Redemption Date to each
Holder of Notes to be redeemed. If less



                                       5
<PAGE>

than all the Notes are to be redeemed at the option of the Company, the Trustee
shall select the Notes to be redeemed in whole or in part by random lot.

                  This Note is not subject to a sinking fund. Holders of Notes
will not be permitted to require the Company to redeem or repurchase the Notes
at their option.

                  In case an Event of Default shall have occurred and be
continuing with respect to the Notes, the principal hereof may be declared, and
upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions 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. An Event of Default with respect to the Senior Debt Security
of any other Series issued under the Indenture, including the failure to make
any payment of principal or interest with respect thereto when and as due, will
not necessarily be an Event of Default with respect to the Notes.

                  The Indenture, as supplemented by the Indenture Supplement
relating to the Notes, contains provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, evidenced as in
the Indenture provided, to execute supplemental indentures adding any provisions
to or changing in any manner or eliminating any of the provisions of the
Indenture or of any supplemental indenture or modifying in any manner the rights
of the Holders of the Notes; provided, however, that no such supplemental
indenture shall (i) extend the fixed maturity of any Notes, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any premium payable on the redemption thereof,
without the consent of the Holder of each Note so affected, or (ii) reduce the
aforesaid percentage of Notes, the consent of the Holders of which is required
for any such supplemental indenture, without the consent of the Holders of all
Notes then outstanding. The Indenture also provides that the Holders of a
majority in aggregate principal amount of the Notes at the time outstanding may
on behalf of the Holders of all the Notes waive any past default under the
Indenture and its consequences, except a default in the payment of the principal
of or premium, if any, or interest on any of the Notes. Any such consent or
waiver by the Holder of this Note (unless revoked as provided in the Indenture)
shall be conclusive and binding upon such Holder and upon all future Holders and
owners of this Note and of any Note issued in exchange or substitution herefor,
whether or not any notation of such consent or waiver is made upon this Note.

                  As set forth in, and subject to, the provisions of the
Indenture, no Holder of any Note will have any right to institute any proceeding
with respect to the Indenture or for any remedy thereunder, unless such Holder
shall have previously given to the Trustee written notice of default in respect
of the Notes and of the continuance thereof, and unless the Holders of not less
than 25 percent in aggregate principal amount of the Notes then outstanding
shall have made written request upon the Trustee to institute such action or
proceedings in its own name as Trustee hereunder and shall have furnished to the
Trustee such reasonable indemnity as it may require, and the Trustee shall have
failed to institute such proceeding within 60 calendar days; provided, however,
that such limitations do not apply to a suit instituted by the Holder hereof for



                                       6

the enforcement of payment of the principal of and any premium or interest on
this Note on or after the respective due dates expressed herein.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Note is registrable in the
Senior Debt Security Register upon surrender of this Note for registration of
transfer at the office or agency maintained by the Company for such purpose,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Senior Debt Security Registrar duly executed
by the Holder hereof or his attorney duly authorized in writing, and thereupon
one or more new Notes, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

                  The Notes are issued only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof. A Holder may
transfer or exchange Notes in accordance with the Indenture.

                  No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of, premium, if any,
and interest on this Note at the times, places and rates, and in the coin or
currency, herein prescribed.

                  The Indenture, as supplemented by the Indenture Supplement
relating to the Notes, contains provisions for legal defeasance at any time of
the entire indebtedness of this Note or defeasance of certain restrictive
covenants with respect to this Note, in each case upon compliance by the Company
with certain conditions set forth therein.

                  The Company, the Trustee, any paying agent and any Senior Debt
Security Registrar for the Notes may deem and treat the Holder hereof as the
absolute owner of this Note (whether or not this Note shall be overdue and
notwithstanding any notation of ownership or other writing hereon made by anyone
other than the Company or any such Senior Debt Security Registrar), for the
purpose of receiving payment hereof or on account hereof and for all other
purposes, and neither the Company nor the Trustee nor any paying agent nor any
such Senior Debt Security Registrar shall be affected by any notice to the
contrary.

                  No recourse shall be had for the payment of the principal of,
or premium, if any, or 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 the Company or of any
successor corporation, 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.
