Ladies and Gentlemen:

         Centex Corporation, a Nevada corporation (the "Company"), confirms its
agreement with each of you (individually, an "Agent" and collectively, the
"Agents") with respect to the issue


<PAGE>   2



and sale from time to time by the Company of its Senior Medium-Term Notes,
Series C (the "Senior Notes") and its Subordinated Medium-Term Notes, Series C
(the "Subordinated Notes"), each due 9 months or more from date of issue (the
Senior Notes and the Subordinated Notes are herein collectively referred to as
the "Notes"). The Senior Notes will be issued under a Senior Indenture (the
"Senior Indenture") dated as of October 1, 1998, as supplemented by a third
Supplemental Indenture thereto dated as of January 27, 2000, and the
Subordinated Notes will be issued under a Subordinated Indenture (the
"Subordinated Indenture") dated as of March 12, 1987, as supplemented by a sixth
Supplemental Indenture thereto dated as of January 27, 2000, as each may be
amended, supplemented or modified from time to time. The Senior Indenture and
the Subordinated Indenture are individually referred to herein as an "Indenture"
and collectively referred to herein as the "Indentures". The Indentures are each
between the Company and Chase Bank of Texas, National Association (formerly
Texas Commerce Bank National Association), as Trustee (the "Trustee").

         As of the date hereof, the Company has authorized the issuance and sale
of up to $400,000,000 aggregate initial offering price of Notes to the Agents as
principal or through the Agents as agent pursuant to the terms of this
Agreement. It is understood, however, that the Company may from time to time
authorize the issuance and sale of additional Notes and that such additional
Notes may be sold to or through the Agents pursuant to the terms of this
Agreement, all as though the issuance and sale of such Notes were authorized as
of the date hereof.

         If Notes are sold by the Company to an Agent as principal, such Agent
may purchase as principal for resale to investors and other purchasers in
accordance with the provisions of Section 2(a) hereof, and, if requested by such
Agent, the Company will enter into a Terms Agreement relating to such sale
(each, a "Terms Agreement"). If Notes are sold by the Company directly to
investors (as may from time to time be agreed to by the Company and an Agent),
such Agent will act as agent of the Company in soliciting purchases of the Notes
in accordance with the provisions of Section 2(b) hereof.

         Subject to the terms and conditions stated herein and subject to the
reservation by the Company of the right to sell Notes directly on its own
behalf, the Company hereby agrees that the Notes will be sold to or through the
Agents. The Company hereby appoints each Agent as its agent for the purpose of
soliciting and receiving offers to purchase Notes from the Company by others
and, on the basis of the representations and warranties herein contained, but
subject to the terms and conditions herein set forth, each Agent severally and
not jointly agrees to use reasonable best efforts to solicit and receive offers
to purchase Notes upon terms acceptable to the Company at such times and in such
amounts as the Company shall from time to time specify.

         For purposes of this Agreement, all references to the Registration
Statement (as hereinafter defined), any preliminary prospectus, the Prospectus
(as hereinafter defined) or any amendment or supplement to any of the foregoing
shall be deemed to include the copy filed with the Securities and Exchange
Commission (the "SEC") pursuant to its Electronic Data Gathering, Analysis and
Retrieval system ("EDGAR").

         1. Representations and Warranties. The Company represents and warrants
to and agrees with each Agent as of the date hereof, as of the date of each
acceptance by the Company of an offer to purchase Notes (whether to an Agent as


                                       2
<PAGE>   3



principal or through an Agent as agent), as of the date of each delivery of
Notes (whether to an Agent as principal or through an Agent as agent) (the date
of each such delivery being hereinafter referred to as a "Settlement Date") and
as of each date the Registration Statement (as hereinafter defined) or the
Prospectus (as hereinafter defined) is amended or supplemented (other than by an
amendment or supplement providing solely for a change in the interest rates,
redemption provisions, amortization schedules, maturities or other similar terms
offered on the Notes (whether pursuant to a term sheet or otherwise), and,
unless an Agent shall otherwise specify, other than by an amendment or
supplement which relates exclusively to an offering of debt securities other
than Notes) or there is filed with the SEC any document that is incorporated by
reference into the Registration Statement or the Prospectus (each of the times
referenced above being referred to as a "Representation Date"), as follows (it
being understood that such representations, warranties and agreements shall be
deemed to relate to the Registration Statement and the Prospectus, each as
amended or supplemented to each such date):

         (a) The Company has filed with the SEC a registration statement (File
No. 333-94221) in respect of the Notes in the form heretofore delivered or to be
delivered to each Agent (the various parts of such registration statement, the
Prospectus, all exhibits thereto (other than the Statements of Eligibility under
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act") of a
corporation designated to act as Trustee, on Form T-1), each as amended, at the
time such registration statement or amendment thereto became effective, being
hereinafter collectively called the "Registration Statement") and the
Registration Statement (and any further registration statements which may be
filed by the Company for the purpose of registering additional Notes, including
any registration statement filed pursuant to Rule 462(b) of the regulations to
the Securities Act) in such form has been declared effective by the SEC and no
stop order suspending the effectiveness of the Registration Statement as amended
has been issued and no proceeding for that purpose has been initiated or
threatened by the SEC, and any requests on the part of the SEC for additional
information have been complied with (any preliminary prospectus included in the
Registration Statement as amended being hereinafter called a "Preliminary
Prospectus;" the prospectus relating to debt securities of the Company
registered pursuant to the Registration Statement (including the Notes) and the
prospectus supplement or term sheet relating to any particular issuance of
Notes, in the form in which it has most recently been filed, or transmitted for
filing, with the SEC on or prior to the date of this Agreement, being
hereinafter collectively called the "Prospectus", except that if any revised
Prospectus shall be provided to each Agent by the Company for use in connection
with the offering of the Notes which is not required to be filed by the Company
pursuant to Rule 424(b) under the Securities Act, the term "Prospectus" shall
refer to such revised prospectus from and after the time it is first provided to
each Agent for such use; any reference herein to any Preliminary Prospectus or
the Prospectus shall be deemed to refer to and include the documents
incorporated by reference therein pursuant to Item 12 of Form S-3 under the
Securities Act of 1933, as amended (the "Securities Act"), as of the date of
such Preliminary Prospectus or Prospectus, as the case may be; any reference to
any amendment or supplement to the Registration Statement or any part thereof
shall be deemed to refer to and include any documents filed after the date of
the Registration Statement or any such part thereof under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and incorporated by
reference in such amendment or supplement; and any reference to the Prospectus,
as amended or supplemented, shall be deemed to refer to the Prospectus as
amended or supplemented in relation to the applicable Notes in the form in which
it is first filed, or transmitted for filing, with the SEC pursuant to Rule 424
under the Securities Act, including any documents incorporated by


                                       3
<PAGE>   4



reference therein as of the date of such filing or transmission; any references
to information "set forth in," "stated in," or "described in" the Registration
Statement or the Prospectus or references of like import shall include any
information contained in documents incorporated by reference therein);

         (b) The documents incorporated by reference in the Registration
Statement, when they were filed or hereafter are filed with the SEC, conformed
or when so filed will conform, in all material respects to the requirements of
the Exchange Act and the rules and regulations of the SEC thereunder; and any
further documents so filed and incorporated by reference in the Prospectus, when
such documents are filed with the SEC, will conform in all material respects to
the requirements of the Exchange Act and the rules and regulations of the SEC
thereunder;

         (c) Each part of the Registration Statement and the Prospectus
conformed, and as of the applicable Representation Date will conform, and any
amendments or supplements to the Registration Statement or the Prospectus will
conform, on the date of filing thereof with the SEC, in all material respects to
the requirements of the Securities Act and the Trust Indenture Act, as
applicable, and the rules and regulations of the SEC thereunder; the
Registration Statement and any amendment thereto, as of the applicable effective
date, did not and at each time thereafter at which any amendment to the
Registration Statement becomes effective and any Annual Report on Form 10-K is
filed by the Company with the SEC as of each Representation Date, will not,
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; the Prospectus and any supplement thereto, as of the applicable
filing date, did not and as of each Representation Date will not, contain an
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading; provided, however, that the
representations and warranties in this section shall not apply to any statements
or omissions made in reliance upon and in conformity with information furnished
in writing to the Company by or on behalf of any Agent expressly for use in the
Registration Statement or Prospectus. Each Preliminary Prospectus and the
Prospectus delivered to the Agents for use in connection with the offering of
the Notes was identical to the electronically transmitted versions thereof filed
with the SEC pursuant to EDGAR, except to the extent permitted by Regulation
S-T;

distributions of any kind declared, paid or made by the Company in respect of

         (e) The Company and its subsidiaries have indefeasible title in fee
simple to all real property and indefeasible title to all personal property
owned by them, in each case free and clear of all liens, encumbrances and
defects except such as are described in the Prospectus or such as are not

in any such jurisdiction;

         (g) The Company has an authorized capitalization as set forth, or as

which the Company or any of its subsidiaries is a party or by which the Company

in any violation of the provisions of the Articles of Incorporation, as amended
or restated, or the Bylaws of the Company or any statute or order, rule or
regulation of any court or governmental agency or body having jurisdiction over
the Company or any of its subsidiaries or any of their properties; and no

are no legal or governmental proceedings pending to which the Company or any of
its subsidiaries is a party or of which any property of the Company or any of

adverse effect on the consolidated financial position, stockholders' equity or

to operate in compliance with which would have a material adverse effect on the
business of the Company and its subsidiaries, taken as a whole, and the Company
has received no notice of proceedings relating to the revocation or modification
of any such certificate, authority or permit that, singly or in the aggregate,

adversely affect the business, assets, financial position or prospects of the

indemnification hereunder may be limited by applicable laws or equity
principles;

subsidiaries owns or possesses all of the patents, trademarks, service marks,
trade names, copyrights and licenses and rights with respect to the foregoing,

with the rights of others, the result of which conflict would materially and
adversely affect the business, assets, financial position or prospects of the
Company and its subsidiaries, taken as a whole;

         (q) There are no contracts, indentures, mortgages, loan agreements,
notes, bonds, debentures, other evidences of indebtedness, leases or other

any existing or imminent labor disturbance by the employees of any of its
principal suppliers, that might reasonably be expected to materially


                                       7

adversely affect the business, assets, financial position or prospects of the

have been satisfied with respect to the Company and the Registration Statement
and Prospectus;

         (t) The Remarketing Agreement, if applicable, has been duly and validly
authorized, executed and delivered by the Company and, assuming the Remarketing
Agreement has been duly authorized, executed and delivered by the Remarketing
Agent (as defined in the Prospectus), will be a valid and legally binding
agreement of the Company; and

         (u) Neither the Company nor any of its subsidiaries is required to be
registered under the Investment Company Act of 1940, as amended.

         Any certificate signed by any director or officer of the Company and
delivered to the Agents or their counsel in connection with an offering of Notes
to an Agent as principal or through an Agent as agent shall be deemed a
representation and warranty by the Company to such Agent as to the matters
covered thereby on the date of such certificate and at each Representation Date
subsequent thereto.

         2. Purchases as Principal; Solicitations as Agent.

         (a) No Agent shall have any obligation to purchase Notes from the
Company as principal, but an Agent may agree from time to time to purchase Notes
as principal. Each sale of Notes to an Agent as principal shall be made in
accordance with the terms of this Agreement, except as otherwise agreed by such
Agent and the Company, and, if requested by such Agent, the Company will enter
into a Terms Agreement that will provide for the sale of such Notes to and the
purchase thereof by such Agent. Each Terms Agreement will be either (i)
substantially in the form of Exhibit A (in the case of Senior Notes) or Exhibit
B (in the case of Subordinated Notes) hereto, (ii) in the form of an exchange of
any form of written telecommunication between an Agent and the Company or (iii)
an oral agreement between an Agent and the Company confirmed in writing by such
Agent to the Company.

         Each agreement by an Agent to purchase Notes as principal (whether or
not set forth in a Terms Agreement) shall specify the principal amount of Notes
to be purchased by such Agent pursuant thereto, the maturity date of such Notes,
the price to be paid to the Company for such Notes, the interest rate and
interest rate formula, if any, applicable to such Notes and any other terms of
such Notes. Each such agreement shall also specify any requirement for officers'
certificates, opinions of counsel and letters from the independent public
accountants to the Company pursuant to Sections 5 and 6 hereto.

         Each Terms Agreement shall specify the time and place of delivery of
and payment for such Notes. With respect to each sale of Notes to an Agent as
principal that is not made pursuant to a Terms Agreement, the procedural details
relating to the issue and delivery of such Notes and the payment therefor shall
be as set forth in the Administrative Procedures (as hereinafter defined).


                                       8
<PAGE>   9



         Each purchase of Notes by an Agent as principal, unless otherwise
agreed, shall be at a discount from the principal amount of each such Note
equivalent to the applicable commission set forth in Subsection (b) hereof. Each
Agent may engage the services of any other broker or dealer in connection with
the resale of any Notes purchased by such Agent as principal and may allow all
or any portion of the discount received in connection with such purchases from
the Company to such brokers and dealers.

         (b) If agreed upon by an Agent and the Company, such Agent, acting
solely as agent for the Company and not as principal, will solicit purchasers of
the Notes. In connection with the Agents' actions as agents hereunder, each
Agent agrees to use reasonable best efforts to solicit offers to purchase Notes
from the Company upon the terms and conditions set forth in the Prospectus (and
any supplement thereto) and in the Administrative Procedures. In soliciting
offers to purchase the Notes as agents, each Agent is acting solely as an agent
for the Company, and not as a principal, and does not assume any obligation
toward or relationship of agency or trust with any purchaser of Notes. Each
Agent shall make reasonable efforts to assist the Company in obtaining
performance by each purchaser whose offer to purchase Notes has been solicited
by such Agent and accepted by the Company, but no Agent shall have any liability
to the Company in the event any such purchase is not consummated for any reason.
If the Company shall default in its obligations to deliver Notes to a purchaser
whose offer it has accepted, the Company shall hold each Agent harmless against
any loss, claim, damage or liability arising from or as a result of such default
and shall, in particular, pay to each Agent the commission each Agent would have
received had such sale been consummated.

         The Company may appoint additional agents in connection with the
offering of the Notes; provided that (i) the Company promptly notifies each
Agent of such appointment and (ii) the commission paid to any such additional
agent with respect to the sale of Notes by the Company as a result of a
solicitation made by such additional agent is the same as that percentage
specified below of the aggregate principal amount of such Notes sold by the
Company; and provided further that, unless the appointment of such additional
agent is expressly limited to the solicitation of offers to purchase a specified
principal amount of Notes on specified terms, such additional agent enters into
an agreement with the Company making such agent an Agent under this Agreement or
enters into an agreement with the Company on terms which are substantially
similar to those contained in this Agreement, which agreement shall include
appropriate changes to reflect the arrangements between the Company and such
additional agent. The Company may from time to time offer Notes for sale
otherwise than through an Agent.

         No Agent is authorized to appoint sub-agents with respect to Notes sold
through an Agent as agent.

         The Company reserves the right, in its sole discretion, to instruct the
Agents to suspend at any time, for any period of time or permanently, the
solicitation of offers to purchase Notes (other than Notes held by the Agents
that were purchased from the Company as principal). As soon as practicable after
receipt of instructions from the Company, each Agent will forthwith suspend
solicitations of offers to purchase Notes from the Company until such time as
the Company has advised the Agents that such solicitation may be resumed. While
such solicitation is suspended, the Company shall not be required to deliver any
certificates, opinion or letter in accordance with Sections 6(a), (b) and (c);
provided, however, that if the Registration Statement or the Prospectus is
amended or supplemented during the period of suspension (other than by an


                                       9
<PAGE>   10



amendment or supplement providing solely for a change in the interest rates of
the Notes or for a change the Agents deem to be immaterial), no Agent shall be
required to resume soliciting offers to purchase Notes until the Company has
delivered such certificates, opinions and letters an Agent may request. The
Company also reserves the right to sell Notes directly to purchasers in those
jurisdictions in which it is authorized to do so.

         Except as otherwise agreed, the Company agrees to pay to each Agent, as
consideration for the sale of each Note resulting from a solicitation made or an
offer to purchase received by such Agent, a commission in the form of a discount
from the purchase price of such Note equal to the following percentage of the
principal amount of such Note:

- ---------------
* Or Initial Rate Period, in the case of Remarketed Notes.

         Each Agent shall communicate to the Company, orally or in writing, each
offer to purchase Notes received by an Agent as agent that in such Agent's
judgment should be considered by the Company. The Company shall have the sole
right to accept offers to purchase Notes and may reject any offer in whole or in
part. Each Agent shall have the right to reject any offer to purchase Notes that
such Agent considers to be unacceptable, and any such rejection shall not be
deemed a breach of such Agent's agreements contained herein.

         Delivery of Notes sold through an Agent as agent shall be made by the
Company to such Agent for the account of any purchaser against payment therefor
in immediately available funds. In the event that a purchaser shall fail either
to accept delivery of or to make payment for a Note on the date fixed for
settlement, an Agent shall promptly notify the Company and deliver such Note to
the Company and if such Agent has theretofore paid the Company for such Note,
the Company will promptly return such funds to such Agent. If such failure
occurred for any reason other than default by an Agent in the performance of its
obligations hereunder, the Company will reimburse such Agent on an equitable
basis for its loss of the use of the funds for the period such funds were
credited to the Company's account.


                                       10
<PAGE>   11



         (c) The Company and each Agent agree that any Notes purchased by an
Agent shall be purchased, and any Notes the placement of which an Agent arranges
as agent shall be placed by such Agent, in reliance on the representations,
warranties, agreements and covenants of the Company contained herein and on the
terms and conditions and in the manner provided herein.

         (d) The purchase price, interest rate or formula, maturity date and
other terms of the Notes (as applicable) shall be agreed upon by the Company and
each Agent and specified in a pricing supplement to the Prospectus (each, a
"Pricing Supplement") to be prepared in connection with each sale of Notes.
Except as otherwise specified in the applicable Pricing Supplement, the Notes
will be issued in denominations of U.S. $1,000, except for Remarketed Notes
which will be issued in minimum denominations of $100,000, or any larger amount
that is an integral multiple thereof. Each Agent and the Company agree to
perform the respective duties and obligations specifically provided to be
performed in the Medium-Term Notes Administrative Procedures (attached hereto as
Exhibit C) (the "Administrative Procedures"), as amended from time to time. The
Administrative Procedures may be amended only by written agreement of the
Company, each Agent and the Trustee. The Company will furnish to the Trustee a
copy of the Administrative Procedures as from time to time in effect. The
Company agrees to cause the Trustee to agree to perform the duties and
obligations specifically provided to be performed by the Trustee in such
Administrative Procedures.

         3. Agreements. The Company agrees with each Agent that:

         (a) The Company will notify each Agent immediately, and confirm such
notice in writing, of (i) the effectiveness of any amendment to the Registration
Statement, (ii) the transmittal to the SEC for filing of any amendment or
supplement to the Prospectus or any document to be filed pursuant to the
Exchange Act which will be incorporated by reference in the Prospectus (other
than any amendment, supplement or document relating solely to securities other
than the Notes), (iii) the receipt of any comments from the SEC with respect to
the Registration Statement or the Prospectus, (iv) any request by the SEC for
any amendment to the Registration Statement or any amendment or supplement to
the Prospectus or for additional information, and (v) the issuance by the SEC of
any stop order suspending the effectiveness of the Registration Statement or the
initiation of any proceedings for that purpose. The Company will make every
reasonable effort to prevent the issuance of any stop order and, if any stop
order is issued, to obtain the lifting thereof at the earliest possible moment.

         (b) The Company will give each Agent notice of its intention to file or
prepare any additional registration statement with respect to the registration
of additional Notes, any amendment to the Registration Statement or any
amendment or supplement to the Prospectus (other than an amendment or supplement
providing solely for a change in the interest rates or formula applicable to the
Notes or relating solely to the issuance and/or offering of securities other
than the Notes), whether by the filing of documents pursuant to the Exchange
Act, the Securities Act or otherwise, and will furnish each Agent with copies of
any such amendment or supplement or other documents proposed to be filed or
prepared a reasonable time in advance of such proposed filing or preparation, as
the case may be, and will not file any such amendment or supplement or other
documents in a form to which an Agent or its counsel shall reasonably object.


                                       11
<PAGE>   12



         (c) The Company will deliver to the Agents as many signed and conformed
copies of the Registration Statement (as originally filed) and of each amendment
thereto (including exhibits filed therewith or incorporated by reference therein
and documents incorporated by reference in the Prospectus) as the Agents may
reasonably request. The Company will furnish to the Agents as many copies of the
Prospectus as the Agents shall reasonably request so long as the Agents are
required to deliver a Prospectus in connection with sales or solicitations of
offers to purchase the Notes.

         (d) The Company will prepare, with respect to any Notes to be sold to
or through an Agent pursuant to this Agreement, a Pricing Supplement with
respect to such Notes in a form previously approved by such Agent and will file
such Pricing Supplement pursuant to Rule 424(b)(3) under the Securities Act not
later than the close of business of the SEC on the second business day after the
date on which such Pricing Supplement is first used.

         (e) Except as otherwise provided in subsection (m) of this Section, if
at any time during the term of this Agreement any event shall occur or condition
exist as a result of which it is necessary, in the reasonable opinion of your
counsel or counsel for the Company, to further amend or supplement the
Prospectus in order that the Prospectus will not include an untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements therein not misleading in the light of the circumstances existing
at the time the Prospectus is delivered to a purchaser, or if it shall be
necessary, in the reasonable opinion of either such counsel, to amend or
supplement the Registration Statement or the Prospectus in order to comply with
the requirements of the Securities Act or the regulations to the Securities Act,
immediate notice shall be given, and confirmed in writing, to each Agent to
cease the solicitation of offers to purchase the Notes in such Agent's capacity
as agent and to cease sales of any Notes an Agent may then own as principal
pursuant to an agreement by such Agent to purchase Notes as principal, and the
Company will promptly prepare and file with the SEC such amendment or
supplement, whether by filing documents pursuant to the Exchange Act, the
Securities Act or otherwise, as may be necessary to correct such untrue
statement or omission or to make the Registration Statement and Prospectus
comply with such requirements.

         (f) Except as otherwise provided in subsection (m) of this Section, if
reasonably requested by an Agent, on or prior to the date on which there shall
be released to the general public interim financial statement information
related to the Company with respect to each of the first three quarters of any
fiscal year or preliminary financial statement information with respect to any
fiscal year, the Company shall, to the extent lawful under the rules and
regulations of the SEC, furnish such information to such Agent, confirmed in
writing. The Company shall cause the Prospectus to be amended or supplemented to
include or incorporate by reference financial information with respect thereto
and corresponding information for the comparable period of the preceding fiscal
year, as well as such other information and explanations as shall be necessary
for an understanding thereof or as shall be required by the Securities Act or
the regulations to the Securities Act.

         (g) Except as otherwise provided in subsection (m) of this Section, if
reasonably requested by an Agent, on or prior to the date on which there shall
be released to the general public financial information included in or derived
from the audited financial statements of the Company for the preceding fiscal
year, the Company shall furnish, to the extent lawful under the rules and
regulations of the SEC, such information to such Agent, confirmed in writing,
and shall


                                       12
<PAGE>   13



cause the Registration Statement and the Prospectus to be amended or
supplemented, whether by the filing of documents pursuant the Exchange Act, the
Securities Act or otherwise, to include or incorporate by reference such audited
financial statements and the report or reports, and consent or consents to such
inclusion or incorporation by reference, of the independent accountants with
respect thereto, as well as such other information and explanations as shall be
necessary for an understanding of such financial statements or as shall be
required by the Securities Act or the Securities Act Regulations.

         (h) The Company will make generally available to its security holders
as soon as practicable, but not later than 90 days after the close of the period
covered thereby, an earnings statement (in form complying with the provisions of
Rule 158 under the Securities Act) covering each twelve-month period beginning,
in each case, not later than the first day of the Company's fiscal quarter next
following the "effective date" (as defined in such Rule 158) of the Registration
Statement with respect to each sale of Notes.

         (i) The Company will endeavor, in cooperation with the Agents, to
qualify the Notes for offering and sale under the applicable securities laws of
such states and other jurisdictions of the United States as the Agents may
designate, and will maintain such qualifications in effect for as long as may be
required for the distribution of the Notes; provided, however, that the Company
shall not be obligated to file any general consent to service of process or to
qualify as a foreign corporation in any jurisdiction in which it is not so
qualified. The Company will file such statements and reports as may be required
by the laws of each jurisdiction in which the Notes have been qualified as above
provided. The Company will promptly advise the Agents of the receipt by the
Company of any notification with respect to the suspension of the qualification
of the Notes for sale in any such state or jurisdiction or the initiating or
threatening of any proceeding for such purpose.

         (j) The Company, during the period when a Prospectus is required to be
delivered under the Securities Act or the Exchange Act, will file promptly all
documents required to be filed with the SEC pursuant to Section 13(a), 13(c), 14
or 15(d) of the Exchange Act within the time periods prescribed by the Exchange
Act and the Exchange Act Regulations.

         (k) During the term of this Agreement, the Company shall furnish to the
Agents such relevant documents and certificates of officers of the Company
relating to the business, operations and affairs of the Company, the
Registration Statement, the Prospectus, any amendments or supplements thereto,
the Indentures, the Notes, this Agreement, any Terms Agreement, the
Administrative Procedures and the performance by the Company of its obligations
hereunder or thereunder as the Agents may from time to time reasonably request
and shall notify the Agents promptly in writing of any change in the rating
accorded any of the Company's debt securities by any "nationally recognized
statistical rating organization", as such term is defined for purposes of Rule
436(g)(2) under the Securities Act or the public announcement by any nationally
recognized statistical rating organization that it has under surveillance or
review, with possible negative implications, its rating of any debt securities
of the Company.

         (l) Between the date of any agreement by an Agent to purchase Notes as
principal and the Settlement Date with respect to such agreement, the Company
will not, without such Agent's prior consent (which consent will not be
unreasonably withheld), offer or sell, or enter


                                       13
<PAGE>   14



into any agreement to sell, any debt securities of the Company (other than the
Notes that are to be sold pursuant to such agreement and bank borrowings and
commercial paper in the ordinary course of business), except as may otherwise be
provided in such agreement.

         (m) The Company shall not be required to comply with the provisions of
subsection (e), (f) or (g) of this Section during any period from the time (i)
an Agent shall have suspended solicitation of purchases of the Notes in its
capacity as agent pursuant to a request from the Company and (ii) an Agent shall
not then hold any Notes as principal purchased pursuant to an agreement by such
Agent to purchase Notes as principal, to the time the Company shall determine
that solicitation of purchases of the Notes should be resumed or shall
subsequently enter into a new agreement with such Agent for such Agent to
purchase Notes as principal.

         4. Payment of Expenses. The Company covenants and agrees with the
Agents that the Company will pay or cause to be paid all expenses incident to
the performance of its obligations under this Agreement including:

                 (i) the preparation and filing of the Registration Statement
         and all amendments thereto and the Prospectus and any amendments or
         supplements thereto;

                 (ii) the preparation, filing and reproduction of this Agreement
         and any Terms Agreements;

                 (iii) the preparation, printing, issuance and delivery of the
         Notes, including any fees and expenses relating to the use of
         book-entry notes;

                 (iv) the fees and disbursements of the Company's accountants
         and counsel, of the Trustee and its counsel, and of any Calculation
         Agent;

                 (v) the reasonable fees and disbursements of your counsel
         incurred in connection with the establishment of the program relating
         to the Notes and incurred from time to time in connection with the
         transactions contemplated hereby;

                 (vi) the qualification of the Notes under state securities laws
         in accordance with the provisions of Section 3(h) hereof, including
         filing fees and the reasonable fees and disbursements of your counsel
         in connection therewith and in connection with the preparation of any
         Blue Sky Survey and any Legal Investment Survey;

                 (vii) the preparation and delivery to each Agent in quantities
         as hereinabove stated of copies of the Registration Statement and any
         amendments thereto, and of the Prospectus and any amendments or
         supplements thereto, and the delivery by each Agent of the Prospectus
         and any amendments or supplements thereto in connection with
         solicitations or confirmations of sales of the Notes;

                 (viii) the preparation, reproducing and delivery to each Agent
         of copies of the Indentures and all supplements and amendments thereto;

                 (ix) any fees charged by rating agencies for the rating of the
         Notes;


                                       14
<PAGE>   15



                 (x) the fees and expenses incurred in connection with the
         listing of the Notes on any securities exchange if the Company agrees
         to list the Notes;

                 (xi) the fees and expenses, if any, incurred with respect to
         any filing with the National Association of Securities Dealers, Inc.;

                 (xii) any advertising and other out-of-pocket expenses an Agent
         incurs with the approval of the Company; and

                 (xiii) the cost of providing any CUSIP or other identification
         numbers for the Notes.

         It is understood, however, that, except as provided in this Section and
Section 7 hereof, each Agent will pay all of its own costs and expenses,
transfer taxes on resale of any of the Notes by an Agent, and any advertising
expenses connected with any offers an Agent may make as principal.

         5. Conditions of Obligations. The obligation of the Agents to purchase
Notes as principal pursuant to any Terms Agreement or otherwise, the Agents'
obligation to solicit offers to purchase Notes as agent of the Company and the
obligation to purchase Notes of any purchaser of Notes sold through an Agent as
agent will be subject to the accuracy of the representations and warranties on
the part of the Company herein, to the accuracy of the statements of the
Company's officers made in each certificate furnished pursuant to the provisions
hereof and to the performance and observance by the Company of all covenants and
agreements herein contained on its part to be performed and observed (in the
case of an Agent's obligation to solicit offers to purchase Notes, at the time
of such solicitation and, in the case of an Agent's or any other purchaser's
obligation to purchase Notes, at the time the Company accepts the offer to
purchase such Notes and at the time of purchase) and (in each case) to the
following additional conditions precedent:

         (a) At the time of such solicitation in the case of (i), (ii) and (v)
below, or the time of such purchase, with respect to (i) to (v), as the case may
be:

                 (i) There shall not have occurred any change, or any
         development involving a prospective change, in the condition, financial
         or otherwise, or in the earnings, business or operations, of the
         Company and its subsidiaries, taken as a whole, from that set forth in
         the Registration Statement (exclusive of any amendment thereto filed
         with the SEC after the date of the Terms Agreement (in the case of a
         purchase of Notes by an Agent as principal) or after the date upon
         which the purchaser became obligated to purchase the Notes (in the case
         of a purchase of Notes through an Agent as agent)) that, in each
         Agent's reasonable judgment, is material and adverse and that makes it,
         in each Agent's reasonable judgment, impracticable to market the Notes
         except, in the case of any purchase of Notes, as disclosed to each
         Agent in writing by the Company before an Agent or such other purchaser
         accepted the offer to purchase such Notes.

                 (ii) No stop order suspending the effectiveness of the
         Registration Statement shall have been issued and no proceeding for
         that purpose shall have been initiated or threatened by the SEC; and
         all requests for additional information on the part of the SEC shall
         have been complied with to each Agent's reasonable satisfaction.


                                       15
<PAGE>   16



                 (iii) There shall not have occurred any (A) suspension or
         material limitation of trading generally on or by, as the case may be,
         the New York Stock Exchange, the American Stock Exchange or the
         National Association of Securities Dealers, Inc., (B) suspension of
         trading of any securities of the Company on any exchange or in the
         over-the-counter market, (C) declaration of a general moratorium on
         commercial banking activities in New York or Texas by either federal,
         New York State or Texas authorities or declaration of a banking
         moratorium by the relevant authorities in the country or countries of
         origin of foreign currency or currencies in which the Notes are
         denominated or payable or (D) outbreak or escalation of hostilities or
         change in financial markets or any calamity or crisis that, in each
         Agent's judgment, is material and adverse and, in the case of any of
         the events described in clauses (iii)(A) through (D), such event,
         singly or together with any other such event, makes it, in each Agent's
         judgment, impracticable to market the Notes or to enforce contracts for
         the sale of the Notes on the terms and in the manner contemplated in
         the Prospectus, as amended or supplemented, except, in the case of any
         purchase of Notes, for any such event occurring before the Company
         accepted the offer to purchase such Notes.

                 (iv) The rating assigned by any "nationally recognized
         statistical rating organization", as that term is defined for purposes
         of Rule 436(g)(2) under the Securities Act, to any debt securities of
         the Company shall not have been lowered nor shall any such rating
         agency have publicly announced that it has under surveillance or
         review, with possible negative implications, its rating of any debt
         securities of the Company.

                 (v) There shall have not come to an Agent's attention any facts
         which would cause such Agent to believe that the Prospectus, at the
         time it was required to be delivered to a purchaser of Notes, included
         an untrue statement of a material fact or omitted to state a material
         fact necessary in order to make the statements therein, in light of the
         circumstances existing at the time of delivery, not misleading. As used
         in this clause, "Prospectus" means the Prospectus in the form first
         provided to each Agent for use in confirming sales of the related
         Notes.

         (b) On the date hereof and, if called for by any agreement by an Agent
to purchase Notes as principal, on the corresponding Settlement Date, each Agent
shall have received:

                  (A) The opinion, dated as of such date, of Raymond G. Smerge,
         Executive Vice President, Chief Legal Officer and Secretary (as to (i)
         through (vi) and (ix), (x) and (xiii) below) and Baker Botts L.L.P,
         special counsel for the Company (as to (vii), (viii), (xi), (xii),
         (xiv) and (xv) below) to the effect that:

                      (i) The Company has been duly incorporated and is validly
                  existing as a corporation in good standing under the laws of
                  the State of Nevada, with full corporate power and authority
                  to own its properties and conduct its business as described in
                  the Prospectus and to perform its obligations under this
                  Agreement;

                      (ii) The Company has an authorized capitalization as set
                  forth in the Prospectus, as amended or supplemented, and all
                  of the outstanding shares of capital stock of the Company have
                  been duly and validly authorized and issued and are fully paid
                  and nonassessable;


                                       16
<PAGE>   17



                      (iii) The Company has been duly qualified as a foreign
                  corporation for the transaction of business and is in good
                  standing under the laws of each jurisdiction in which the
                  failure to so qualify would have a material adverse effect
                  upon the Company and its subsidiaries, taken as a whole (such
                  counsel being entitled to rely in respect of the opinion in
                  this clause upon certificates issued by various state
                  authorities as deemed necessary by such counsel);

                      (iv) Each subsidiary of the Company has been duly
                  incorporated or organized as a limited liability company and
                  is validly existing as a corporation or limited liability
                  company, as the case may be, in good standing under the laws
                  of its jurisdiction of incorporation or organization, as the
                  case may be, except where the failure to be in good standing
                  would not have a material adverse effect on the Company and
                  its subsidiaries, taken as a whole; each subsidiary of the
                  Company has been duly qualified as a foreign corporation or
                  limited liability company, as the case may be, for the
                  transaction of business and is in good standing under the laws
                  of each jurisdiction in which the failure to so qualify would
                  have a material adverse effect upon the Company and its
                  subsidiaries, taken as a whole (such counsel being entitled to
                  rely in respect of the opinion in this clause upon
                  certificates issued by various state authorities as deemed
                  necessary by such counsel); and all of the outstanding shares
                  of capital stock or outstanding interests of each such
                  subsidiary have been duly and validly authorized and issued,
                  are fully paid and nonassessable, and (except (i) for
                  directors' qualifying shares, (ii) as set forth in Schedule I
                  hereto, and (iii) as otherwise set forth in the Prospectus)
                  are owned directly or indirectly by the Company, free and
                  clear of all liens, encumbrances, equities or claims affecting
                  transferability or voting;

                      (v) To the best of such counsel's knowledge and other than
                  as set forth or contemplated, or incorporated by reference, in
                  the Prospectus, there are no legal or governmental proceedings
                  pending to which the Company or any of its subsidiaries is a
                  party or of which any property of the Company or any of its
                  subsidiaries is the subject which, individually or in the
                  aggregate, could reasonably be expected to have a material
                  adverse effect on the business, assets, financial position or
                  prospects of the Company and its subsidiaries, taken as a
                  whole; and, to the best of such counsel's knowledge, no such
                  proceedings are threatened or contemplated by governmental
                  authorities or threatened by others;

                      (vi) This Agreement and any applicable Terms Agreement
                  with respect to the Notes have been duly authorized, executed
                  and delivered by the Company.

                      (vii) The Notes, in the form(s) certified by the Company
                  as of the date hereof, will be duly authorized for issuance,
                  offer and sale pursuant to this Agreement when the Pricing
                  Committee of the Board of Directors of the Company has fixed
                  and determined the terms of the Notes to be issued and sold
                  and the Notes, when authorized as aforesaid and when issued,
                  authenticated and delivered in accordance with this Agreement,
                  any applicable Terms Agreement and the applicable Indenture
                  and duly paid for by the purchasers thereof in accordance with
                  this Agreement, any applicable Terms Agreement and the
                  applicable Indenture, will constitute valid and legally
                  binding obligations of the


                                       17
<PAGE>   18



                  Company entitled to the benefits provided by the applicable
                  Indenture and enforceable against the Company in accordance
                  with their respective terms, subject to the Enforceability
                  Exceptions (as hereinafter defined); and the Notes and the
                  Indentures conform in all material respects to the
                  descriptions thereof under the captions "Description of Notes"
                  and "Description of Debt Securities" in the Prospectus;

                      (viii) Each of the Indentures has been duly authorized,
                  executed and delivered by the Company and (assuming the due
                  authorization, execution and delivery of each such Indenture
                  by the Trustee) constitutes a valid and legally binding
                  instrument enforceable against the Company in accordance with
                  its terms, subject to the Enforceability Exceptions; and each
                  of the Indentures has been qualified under the Trust Indenture
                  Act;

                      (ix) The Remarketing Agreement, if applicable, has been
                  duly and validly authorized, executed and delivered by the
                  Company and, assuming the Remarketing Agreement has been duly
                  authorized, executed and delivered by the Remarketing Agent,
                  will be a valid and legally binding agreement of the Company;

                      (x) The issue and sale of the Notes and the compliance by
                  the Company with all of the provisions of the Notes, any
                  Remarketing Agreement, if applicable, the Indentures, and this
                  Agreement and any applicable Terms Agreement and the
                  consummation of the transactions herein and therein
                  contemplated will not violate or result in a breach of any of
                  the terms or provisions of, or constitute a default under, any
                  indenture, mortgage, deed of trust, loan agreement or other
                  agreement or instrument known to such counsel to which the
                  Company or any of its subsidiaries is a party or by which the
                  Company or any of its subsidiaries is bound or to which any of
                  the property or assets of the Company or any of its
                  subsidiaries is subject, except for any such violation, breach
                  or default that would not have a material adverse effect on
                  the Company and its subsidiaries taken as a whole, nor will
                  such action result in any violation of the provisions of the
                  Articles of Incorporation, as amended or restated, or the
                  Bylaws of the Company or any statute or order, rule or
                  regulation of any court or governmental agency or body having
                  jurisdiction over the Company or any of its subsidiaries or
                  any of their properties;

                      (xi) To such counsel's knowledge, no consent, approval,
                  authorization, order, registration or qualification of or with
                  any court or governmental agency or body of the United States
                  of America or the States of Texas or Nevada is required for
                  the performance by the Company of its obligations under this
                  Agreement, for the issue and sale of the Notes or the
                  consummation of the other transactions contemplated by this
                  Agreement, any Terms Agreement, the Remarketing Agreement or
                  the Indentures, except such as have been obtained under the
                  Securities Act and the Trust Indenture Act and such consents,
                  approvals, authorizations, registrations or qualifications as
                  may be required under state securities or Blue Sky laws in
                  connection with the purchase and distribution of the Notes by
                  or through each Agent;


                                       18
<PAGE>   19



                      (xii) To such counsel's knowledge, no proceedings for a
                  stop order with respect to the Registration Statement are
                  pending or threatened under the Securities Act;

                      (xiii) The documents incorporated by reference in the
                  Prospectus, as amended or supplemented (other than the
                  financial statements and related schedules therein, as to
                  which such counsel need express no opinion), when they became
                  effective or were filed with the SEC, as the case may be, and
                  as of the date this opinion is delivered, complied as to form
                  in all material respects with the requirements of the
                  Securities Act or the Exchange Act, as applicable, and the
                  rules and regulations of the SEC thereunder; nothing has come
                  to the attention of such counsel that would cause such counsel
                  to believe that any of such documents, when they became
                  effective or were so filed, as the case may be (other than the
                  financial statements and related schedules therein, as to
                  which such counsel need express no belief), and as of the date
                  this opinion is delivered contained, in the case of a
                  registration statement that became effective under the
                  Securities Act, an untrue statement of a material fact or
                  omitted to state a material fact necessary in order to make
                  the statements therein not misleading, and, in the case of
                  other documents that were filed under the Securities Act or
                  the Exchange Act with the SEC, an untrue statement of a
                  material fact or omitted to state a material fact necessary in
                  order to make the statements therein, in light of the
                  circumstances under which they were made when such documents
                  were so filed, not misleading; and such counsel does not know
                  of any contracts or other documents of a character required to
                  be filed as an exhibit to the Registration Statement or
                  required to be incorporated by reference into the Prospectus
                  or required to be described in the Registration Statement or
                  the Prospectus that are not filed or incorporated by reference
                  or described as required; and

                      (xiv) The Registration Statement and the Prospectus, as
                  amended or supplemented, if applicable (except for (1) the
                  financial statements (including the notes thereto and the
                  auditors' reports thereon) included or incorporated by
                  reference therein, and (2) the other financial information
                  included or incorporated by reference therein, as to which
                  such counsel need express no opinion) appear on their face to,
                  comply as to form in all material respects with the Securities
                  Act and the rules and regulations of the SEC thereunder; and

                      (xv) Such counsel shall also state, in a separate
                  paragraph, the following: "such counsel has participated in
                  conferences with officers and other representatives of the
                  Company, representatives of the independent public accountants
                  of the Company and your representatives at which the contents
                  of the Registration Statement and the Prospectus and related
                  matters were discussed. Although such counsel did not
                  independently verify, is not passing upon, and does not assume
                  any responsibility for, the accuracy, completeness or fairness
                  of the statements contained in the Registration Statement and
                  the Prospectus or the responsiveness of such statements to
                  legal requirements (except to the extent stated in the last
                  clause of paragraph (vii) and paragraph (xiv) above), such
                  counsel advises you that, on the basis of the foregoing
                  (relying in part as to materiality upon officers and other
                  representatives of the Company), no facts have


                                       19
<PAGE>   20



                  come to such counsel's attention which lead such counsel to
                  believe that the Registration Statement (other than (i) the
                  financial statements (including the notes thereto and the
                  auditors' reports thereon) included therein, and (ii) the
                  other financial information included therein, as to which such
                  counsel has not been asked to comment), as of the time it
                  became effective (or if an amendment to the Registration
                  Statement or an Annual Report on Form 10-K has been filed by
                  the Company with the SEC subsequent to the effectiveness of
                  the Registration Statement, then at the time such amendment
                  became effective or at the time of the most recent such
                  filing, as the case may be), contained any untrue statement of
                  a material fact or omitted to state any material fact required
                  to be stated therein or necessary to make the statements
                  therein not misleading or that the Prospectus (other than (i)
                  the financial statements (including the notes thereto and the
                  auditors' report thereon) included therein and (ii) the other
                  financial information included therein, as to which such
                  counsel has not been asked to comment), as of the issue date
                  thereof and as of the date of such counsel's letter, contained
                  or contains any untrue statement of a material fact or omitted
                  or omits to state any material fact required to be stated
                  therein or necessary to make the statements therein, in light
                  of the circumstances in which they were made, not misleading."

                  "Enforceability Exceptions" shall mean (i) applicable
bankruptcy, receivership, insolvency, reorganization, moratorium, fraudulent
conveyance, fraudulent transfer and other similar laws relating to or affecting
the enforcement of the rights and remedies of creditors or parties to executory
contracts generally; (ii) general principles of equity (regardless of whether
such enforceability is considered in a proceeding at law or in equity) and the
exercise of equitable powers by a court of competent jurisdiction (and no
opinion need be given as to the availability of any specific equitable relief or
equitable remedies); and (iii) applicable law or public policy limiting the
enforcement of provisions providing for the indemnification of a party.

                  (B) The opinion, dated as of such date, of Milbank, Tweed,
         Hadley & McCloy LLP, your special counsel, covering the incorporation
         of the Company, the validity of the Remarketing Agreement, if
         applicable, the Indentures, the Notes, the Registration Statement, the
         Prospectus, as amended or supplemented, and other related matters as
         the Agents may reasonably request.

         (c) On the date hereof and, if called for by any Terms Agreement, on
the corresponding Settlement Date, each Agent shall have received a certificate,
dated as of the date hereof or the Settlement Date, as the case may be, signed
by (i) the Chairman, Vice Chairman, President or any Vice President and (ii) the
Chief Financial Officer or Treasurer of the Company to the effect that (x) the
representations and warranties of the Company contained herein are true and
correct as of such date and the Company has complied with all of the agreements
and satisfied all of the conditions on its part to be performed or satisfied on
or before such date and (y) none of the conditions referred to in Section 5(a)
exist.

         The officer signing and delivering such certificate may rely upon the
best of his knowledge as to proceedings threatened.

         (d) On the date hereof and, if required by any Terms Agreement, on the
corresponding Settlement Date, the Company's independent public accountants
shall have

                                       20
<PAGE>   21



furnished to the Agents a letter or letters, dated as of the date hereof or such
Settlement Date, as the case may be, in form and substance satisfactory to the
Agents containing statements and information of the type ordinarily included in
accountant's "comfort letters" to underwriters with respect to the financial
statements and certain financial information contained in or incorporated by
reference into the Registration Statement and the Prospectus.

         (e) On the date hereof and on each Settlement Date, the Company shall
have furnished to the Agents such appropriate further information, certificates,
documents and opinions as the Agents may reasonably request or as the Agents'
counsel may reasonably require for purposes of rendering the opinion referred to
in Section 5(b)(B) and in order to evidence the accuracy and completeness of any
of the representations and warranties, or the fulfillment of any of the
conditions, herein contained; and all proceedings taken by the Company in
connection with the issuance and sale of Notes as herein contemplated shall be
reasonably satisfactory in form and substance to each Agent and its counsel.

         (f) (i) Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus, as amended or supplemented, any
loss or interference with its business from fire, explosion, flood or other
calamity, whether or not covered by insurance, or from any labor dispute or
court or governmental action, order or decree, otherwise than as set forth or
contemplated in the Prospectus, as amended or supplemented, and (ii) since the
respective dates as of which information is given in the Prospectus, as amended
or supplemented, there shall not have been any material change in the capital
stock, outstanding interests (other than through exercise of employee stock
options) or long-term debt of the Company and any of its subsidiaries, taken as
a whole (other than borrowings and repayments made in the ordinary course of
business), or any change, or any development involving a prospective change, in
or affecting the general affairs, management, financial position, stockholders
equity or results of operations of the Company and its subsidiaries, otherwise
than as set forth or contemplated in the Prospectus, the effect of which, in any
such case described in clause (i) or (ii), is in your reasonable judgment so
material and adverse as to make it impracticable or inadvisable to proceed with
the public offering or delivery of the Notes on the terms and in the manner
contemplated in the Prospectus, as amended or supplemented;

         (g) Subsequent to the date of any Terms Agreement relating to the
Notes, the rating assigned by any "nationally recognized statistical rating
organization," as that term is defined for purposes of Rule 436(g)(2) under the
Securities Act, to any debt securities of the Company shall not have been
lowered nor shall any such rating agency have publicly announced that it has
under surveillance or review, with possible negative implications, its rating of
any debt securities of the Company;

         (h) Subsequent to the date of any Terms Agreement relating to the
Notes, there shall not have occurred any of the following: (i) a suspension or
material limitation in trading generally on or by, as the case may be, the New
York Stock Exchange, the American Stock Exchange, or the National Association of
Securities Dealers, Inc.; (ii) a suspension of trading of any securities of the
Company on any exchange or in the over-the-counter market; (iii) a declaration
of a general moratorium on commercial banking activities in New York or Texas by
either federal, New York State or Texas authorities or declaration of a banking
moratorium by the relevant authorities in the country or countries of origin of
foreign currency or currencies in


                                       21
<PAGE>   22



which the Notes are denominated or payable or (iv) outbreak or escalation of
hostilities or change in financial markets or any calamity or crisis that, in
the judgment of any Agent or Agents that is or are a party or parties to such
Term Agreement, is material and adverse and, in the case of any of the events
described in these clauses (h)(i) through (iv), such event, singly or together
with any other such event, makes it in the judgment of any such Agent or Agents,
impracticable or inadvisable to proceed with the public offering or the delivery
of the Notes on the terms and in the manner contemplated in the Prospectus, as
amended or supplemented.

         If any condition specified in this Section 5 shall not have been
fulfilled when and as required to be fulfilled, the Agents may terminate this
Agreement by notice to the Company at any time and any such termination shall be
without liability to the Company, except that the provisions of Sections 3(i),
4, 7, 8, 11, 12, and 15 shall remain in effect.

         6. Additional Agreements of the Company. (a) Each time that (i) the
Registration Statement or the Prospectus shall be amended or supplemented (other
than by an amendment or supplement providing solely for a change in the interest
rates, redemption provisions, amortization schedules, maturities or other
similar terms offered on the Notes (whether pursuant to a term sheet or
otherwise), or for a change the Agents deem to be immaterial, and, unless the
Agents shall otherwise specify, other than by an amendment or supplement which
relates exclusively to an offering of debt securities other than the Notes) or
(ii) there is filed with the SEC any document incorporated by reference into the
Prospectus (other than any Current Report on Form 8-K relating exclusively to
the issuance of debt securities under the Registration Statement, unless the
Agents shall otherwise specify) or (iii) (if required pursuant to the terms of
an agreement by an Agent to purchase Notes as principal) the Company sells Notes
to an Agent pursuant to an agreement by such Agent to purchase Notes as
principal or (iv) the Company sells Notes in a form not previously certified to
the Agents by the Company, the Company shall furnish or cause to be furnished to
each Agent forthwith a certificate dated the date of filing with the SEC of such
supplement or document, the date of effectiveness of such amendment, or the date
of such sale, as the case may be, in form satisfactory to each Agent to the
effect that the statements contained in the certificate referred to in Section
5(c) hereof which were last furnished to such Agent are true and correct at the
time of such amendment, supplement, filing or sale, as the case may be, as
though made at and as of such time (except that such statements shall be deemed
to relate to the Registration Statement and the Prospectus as amended and
supplemented to such time) or, in lieu of such certificate, a certificate of the
same tenor as the certificate referred to in said Section 5(c), modified as
necessary to relate to the Registration Statement and the Prospectus as amended
and supplemented to the time of delivery of such certificate.

         (b) Each time that (i) the Registration Statement or the Prospectus
shall be amended or supplemented (other than by an amendment or supplement
providing solely for a change in the interest rates, redemption provisions,
amortization schedules, maturities or other similar terms offered on the Notes
(whether pursuant to a term sheet or otherwise) or for a change the Agents deem
to be immaterial, and, unless the Agents shall otherwise specify, other than by
an amendment or supplement which relates exclusively to an offering of debt
securities other than the Notes) or (ii) there is filed with the SEC any
document incorporated by reference into the Prospectus (other than any Current
Report on Form 8-K or Quarterly Report on Form 10-Q, unless the Agents shall
reasonably request, as a result of any material development described in such
reports), or (iii) (if required pursuant to the terms of an agreement by an
Agent to purchase


                                       22
<PAGE>   23



Notes as principal) the Company sells Notes to an Agent pursuant to an agreement
by such Agent to purchase Notes as principal or (iv) the Company sells Notes in
a form not previously certified to the Agents by the Company, the Company shall
furnish or cause to be furnished forthwith to each Agent and to its counsel a
written opinion of Baker Botts L.L.P., special counsel for the Company or other
counsel satisfactory to the Agents, and an opinion of Raymond G. Smerge,
Executive Vice President, Chief Legal Officer and Secretary of the Company,
dated the date of filing with the SEC of such supplement or document, the date
of effectiveness of such amendment, or the date of such sale, as the case may
be, in form and substance satisfactory to the Agents, of the same tenor as their
respective opinions referred to in Section 5(b)(A) hereof, but modified, as
necessary, to relate to the Registration Statement and the Prospectus as amended
and supplemented to the time of delivery of such opinion; or, in lieu of such
opinion, counsel last furnishing such opinion to the Agents shall furnish the
Agents with a letter to the effect that the Agents may rely on such last opinion
to the same extent as though it was dated the date of such letter authorizing
reliance (except that statements in such last opinion shall be deemed to relate
to the Registration Statement and the Prospectus as amended and supplemented to
the time of delivery of such letter authorizing reliance).

         (c) Each time that (i) the Registration Statement or the Prospectus
shall be amended or supplemented to include additional financial information
unless the Agents shall otherwise specify, other than an amendment or supplement
which relates exclusively to an offering of debt securities other than the Notes
or there is filed with the SEC any document incorporated by reference into the
Prospectus which contains additional financial information or (ii) (if required
pursuant to the terms of any agreement by an Agent to purchase Notes as
principal) the Company sells Notes to an Agent pursuant to any agreement by such
Agent to purchase Notes as principal, the Company shall cause its independent
public accountants forthwith to furnish each Agent a letter, dated the date of
effectiveness of such amendment, supplement or document with the SEC, or the
date of such sale, as the case may be, in form satisfactory to each Agent, of
the same tenor as the letter referred to in Section 5(d) hereof but modified to
relate to the Registration Statement and the Prospectus, as amended and
supplemented to the date of such letter.

         7. Indemnification.

         (a) Indemnification of the Agent. The Company agrees to indemnify and
hold each Agent and each person, if any, who controls each Agent within the
meaning of Section 15 of the Securities Act harmless as follows:

                           (i) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Registration Statement (or any amendment thereto), or the omission
         or alleged omission therefrom of a material fact necessary to make the
         statements therein not misleading or arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Prospectus (or any amendment or supplement thereto) or the omission
         or alleged omission therefrom of a material fact necessary to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading, unless such untrue statement or omission or such
         alleged untrue statement or omission was made in reliance upon and in
         conformity with information furnished to the Company in writing by each
         Agent expressly for use in the Registration Statement (or any amendment
         thereto) or the Prospectus (or any amendment


                                       23
<PAGE>   24



         or supplement thereto) or in reliance upon the Trustee's Statement of
         Eligibility and Qualification under the Trust Indenture Act of 1939
         filed as an exhibit to the Registration Statement;

                           (ii) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, if such settlement is effected with the written consent of
         the Company; and

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

         (b) Indemnification of Company. Each Agent agrees, severally and not
jointly, to indemnify and hold harmless the Company, its directors, each of its
officers who signed the Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section, as incurred, but only
with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement (or any amendment thereto) or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with information furnished to the Company in writing by such Agent
expressly for use in the Registration Statement (or any amendment thereto) or
the Prospectus (or any amendment or supplement thereto).

         (c) General. Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve such indemnifying party from any liability which it may
have otherwise than on account of this indemnity agreement. Upon such notice, an
indemnifying party may participate at its own expense and, to the extent that it
wishes, jointly with any other indemnifying party, similarly notified, and may
assume the defense thereof with counsel reasonably satisfactory to the
indemnified party. In any proceeding where the indemnifying party has assumed
the defense thereof, the indemnifying party shall be liable to the indemnified
party for any legal or other expenses previously incurred by such indemnified
party in connection with the defense thereof and for reasonable costs of
investigation subsequently incurred. In any such proceeding, any indemnified
party shall have the right to retain its own counsel, but the fees and expenses
of such counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual differing interests between them. In no event
shall the indemnifying parties be liable for the fees and expenses of more than
one counsel (in addition to any local counsel) for all indemnified parties in
connection with any one action or separate but similar or related actions in


                                       24
<PAGE>   25



the same jurisdiction arising out of the same general allegations or
circumstances. No indemnifying party shall, without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 7 or Section 8 hereof (whether or not the indemnified parties
are actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

         8. Contribution.

         (a) If the indemnification provided for in Section 7 is unavailable to
an indemnified party or insufficient in respect of any losses, claims, damages
or liabilities referred to therein in connection with any offering of Notes,
then each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Agents on the other
from the offering of such Notes or (ii) if the allocation provided by clause (i)
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Company on the one hand and the Agents on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Agents on the other in connection with the offering of such Notes shall
be deemed to be in the same respective proportions as the total net proceeds
from the offering of such Notes (before deducting expenses) received by the
Company bear to the total discounts and commissions received by the Agents in
respect thereof. The relative fault of the Company and of each Agent shall be
determined by reference to, among other things, whether the untrue or allegedly
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 by the Agents on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

         (b) The Company and each Agent agree that it would not be just or
equitable if contribution pursuant to this Section 8 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph (a) above. The amount paid
or payable by an indemnified party as a result of the losses, claims, damages
and liabilities referred to in paragraph (a) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 8, no Agent shall be required to contribute any amount in excess of the
amount by which the total price at which the Notes referred to in paragraph (a)
above that were offered and sold to the public through such Agent exceeds the
amount of any damages that such Agent would have otherwise been required to pay
by reason of such untrue or allegedly untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the


                                       25
<PAGE>   26



Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. Each Agent's obligation to
contribute pursuant to this Section 8 is several, in proportion to the
respective principal amounts of Notes referred to in paragraph (a) above
purchased or sold by each Agent, and not joint. The remedies provided for in
this Section 8 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to any indemnified party at law or in equity.

         9. Termination.

         (a) This Agreement may be terminated at any time either by the Company
or by an Agent with respect to such Agent upon the giving of 30 days' written
notice of such termination to the other party hereto. The termination of this
Agreement shall not require termination of any agreement by an Agent to purchase
Notes as principal, and the termination of any such agreement shall not require
termination of this Agreement.

         (b) An Agent may terminate any agreement to purchase Notes from the
Company as principal, immediately upon notice to the Company, at any time prior
to the Settlement Date relating thereto, if (i) there has been, since the date
of such agreement or since the respective dates as of which information is given
in the Prospectus, any material adverse change, or any development involving a
prospective material adverse change, in the condition, financial or otherwise,
or in the earnings, business or operations of the Company and its subsidiaries,
taken as a whole, whether or not arising in the ordinary course of business, or
(ii) a stop order suspending the effectiveness of the Registration Statement
shall have been issued or a proceeding for that purpose shall have been
initiated or threatened by the SEC, or (iii) there shall have occurred any (A)
suspension or material limitation of trading generally on or by, as the case may
be, the New York Stock Exchange, the American Stock Exchange or the National
Association of Securities Dealers, Inc., (B) suspension of trading of any
securities of the Company on any exchange or in the over-the-counter market, (C)
declaration of a general moratorium on commercial banking activities in New York
or Texas by either federal, New York State or Texas authorities or declaration
of a banking moratorium by the relevant authorities in the country or countries
of origin of foreign currency or currencies in which the Notes are denominated
or payable or (D) any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in an Agent's reasonable
judgment, is material and adverse and, in the case of any of the events
described in clauses (iii)(A) through (D), such event, singly or together with
any other such event, makes it, in an Agent's judgment, impracticable or
inadvisable to proceed with the public offering or the delivery of the Notes on
the terms and in the manner contemplated by the Prospectus, as amended or
supplemented, or (iv) the rating assigned by any "nationally recognized
statistical rating organization", as such term is defined for purposes of Rule
436(g)(2) under the Securities Act, to any debt securities of the Company as of
the date of such agreement shall have been lowered since that date or if any
such rating organization shall have publicly announced that it has under
surveillance or review, with possible negative implications, its rating of any
debt securities of the Company, or (v) there shall have come to an Agent's
attention any facts that would cause such Agent to believe that the Prospectus,
at the time it was required to be delivered to a purchaser of Notes, included an
untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in light of the circumstances
existing at the time of such delivery, not misleading. As used in this Section,
the term "Prospectus" means the Prospectus in the form first provided to each
Agent for use in confirming sales of the related Notes.

         (c) In the event of any such termination, neither the Company nor an
Agent as to which this Agreement has been terminated will have any liability to
each other, except that (i) an Agent terminating this Agreement shall be
entitled to any commission earned in accordance with the fifth paragraph of
Section 2(b) hereof, (ii) if at the time of termination (a) an Agent shall own
any Notes purchased pursuant to any agreement by such Agent to purchase Notes as
principal with the intention of reselling them or (b) an offer to purchase any
of the Notes has been accepted by the Company but the time of delivery to the
purchaser or his agent of the Note or Notes relating thereto has not occurred,
the covenants set forth in Sections 2(d), 3 and 6 hereof shall remain in effect
until such Notes are so resold or delivered, as the case may be, and (iii) the
provisions of Sections 3(h) and 4 hereof, the indemnity and contribution
agreements set forth in Sections 7 and 8 hereof, and the provisions of Sections
11, 13 and 15 hereof shall remain in effect.

         10. Failure to Purchase. If the Company and two or more Agents enter
into an agreement pursuant to which such Agents agree to purchase Notes from the
Company as principal and one or more Agents shall fail at the relevant
Settlement Date to purchase the Notes which an Agent is obligated to purchase
(the "Defaulted Notes"), then the nondefaulting Agents shall have the right,
within 24 hours thereafter, to make arrangements for one Agent or one or more
other Agents to purchase all, but not less than all, of the Defaulted Notes in
such amounts as may be agreed upon and upon the terms herein set forth;
provided, however, that if such arrangements shall not have been completed
within such 24-hour period, then:

                           (A) if the aggregate principal amount of Defaulted
                  Notes does not exceed 10% of the aggregate principal amount of
                  Notes to be so purchased by all of such Agents on such
                  Settlement Date, the nondefaulting Agents shall be obligated,
                  severally and not jointly, to purchase the full amount thereof
                  in the proportions that their respective initial purchase
                  obligations bear to the purchase obligations of all
                  nondefaulting Agents; or

                           (B) if the aggregate principal amount of Defaulted
                  Notes exceeds 10% of the aggregate principal amount of Notes
                  to be so purchased by all of such Agents on such Settlement
                  Date, such agreement shall terminate without liability on the
                  part of any nondefaulting Agent.

         No action taken pursuant to this paragraph shall relieve any defaulting
Agent from liability in respect of its default. In the event of any such default
which does not result in a termination of such agreement, either the
nondefaulting Agents or the Company shall have the right to postpone the
relevant Settlement Date for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or the Prospectus or
in any other documents or arrangements.

         11. Representations and Indemnities to Survive. The respective
indemnity and contribution agreements, representations, warranties and other
statements of the Company, its officers and each Agent set forth in or made
pursuant to this Agreement or any agreement by an Agent to purchase Notes as
principal will remain in full force and effect, regardless of any termination of
this Agreement or any such agreement, any investigation made by or on behalf of
an Agent or the Company or any of the officers, directors or controlling persons
referred to in Sections 7 and 8 and delivery of and payment for the Notes.

Agents will act as agents of the Company in soliciting Note purchases. Each sale
of Notes will be made in accordance with terms agreed upon by the related Agent
or Agents and the Company in a Terms Agreement in the form included in Exhibit A

shall apply to the offer and sale of the relevant Notes.

will be either Senior Debt Securities ("Senior Notes") or Subordinated Debt
Securities ("Subordinated Notes"). The Senior Notes will be issued under an
Indenture, dated as of October 1, 1998, as supplemented by an Indenture
Supplement No. 3 thereto dated as of January 27, 2000 (the "Senior Indenture"),
and the Subordinated Notes will be issued under an Indenture dated as of March
12, 1987, as supplemented by an Indenture Supplement No. 6 thereto dated as of
January 27, 2000 (the "Subordinated Indenture" and, together with the Senior
Indenture, the "Indentures"), as each may be amended, supplemented or modified
from time to time, between the Company and Chase Bank of Texas, National
Association, as trustee with respect to the Notes (formerly, Texas Commerce Bank
National Association) (together with any successor in such capacity, the
"Trustee"). In accordance with the provisions of the Indentures, the Trustee
will act as Authenticating Agent, Transfer Agent and Paying Agent with respect
to the Notes. Unless the context otherwise requires, references herein to the
Indentures include the form of Note adopted in accordance with the terms of the
Indentures.

         A Registration Statement on Form S-3 (No. 333-94221) (the "Registration
Statement"), with respect to debt securities, including the Notes, has been
filed under the Securities Act of 1933, as amended (the "1933 Act"), with the
Securities and Exchange Commission (the "Commission") and

Company ("DTC"), and recorded in the book-entry system maintained by DTC, or (b)

purchaser. Owners of beneficial interests in Notes issued in book-entry form
will be entitled to physical delivery of Notes in certificated form equal in
principal amount to their respective beneficial interests only upon certain
limited circumstances described in the Prospectus.

         As set forth in the Prospectus, the Company shall appoint one or more
remarketing agents (each, a "Remarketing Agent" and, collectively, the
"Remarketing Agents") with respect to the Remarketed Notes pursuant to a
remarketing agreement (the "Remarketing Agreement").

         General procedures relating to the initial issuance of Notes are set
forth in Part I hereof. Certain procedures relating to the initial issuance of
Notes issued in book-entry form and for remarketing of Remarketed Notes are set

and the Distribution Agreement, the Remarketing Agreement, the Letters of
Representations or the Indentures, the latter documents shall govern.

                                 purchase Notes solicited by the Offering Agent

                                 any such rejection shall not be a breach of the

                                 purchase of Notes, in whole or in part, and any
                                 such rejection shall not be a breach of the
                                 Company's agreement contained in the
                                 Distribution Agreement. The Offering Agent has
                                 agreed to make reasonable efforts to assist the
                                 Company in obtaining performance by each

                                 with respect to an original Note (or any

                                 such payment or provision has been made, the
                                 Original Issue Date of the predecessor Note or
                                 Notes), regardless of the date of
                                 authentication of such subsequently issued
                                 Note. No Global Note shall represent any Note
                                 issued in certificated form.

Identification:                  The Company has arranged with the CUSIP Service
                                 Bureau of Standard & Poor's Ratings Services
                                 (the "CUSIP Service Bureau") for the
                                 reservation of two series of CUSIP numbers,
                                 each series consisting of approximately 900
                                 CUSIP numbers which have been reserved for and
                                 relate to the Senior Fixed Rate and Senior
                                 Floating Rate Global Notes in the first
                                 instance, to the Remarketed Global Notes in the
                                 second instance, and to the Subordinated Fixed
                                 Rate and Subordinated Floating Rate Global
                                 Notes in the third instance. The Company has
                                 delivered to each of the Trustee and DTC such
                                 list of such CUSIP numbers.

                                 The Trustee will assign CUSIP numbers to the
                                 Global Notes upon initial issuance and upon
                                 remarketing in the case of Remarketed Notes as
                                 described above and then advise the Company by
                                 telephone and facsimile transmission or other
                                 electronic transmission of such CUSIP number,
                                 after receiving from the Company the
                                 information specified in Part I above or, as
                                 the case may be, Part IV below.

                                 DTC will notify the CUSIP Service Bureau
                                 periodically of the CUSIP numbers that the
                                 Trustee has assigned to the Global Notes. The
                                 Trustee will notify the Company at any time
                                 when

                                 fewer than 100 of the reserved CUSIP numbers
                                 remain unassigned to the Global Notes, and, if
                                 it deems necessary, the Company will reserve
                                 and obtain additional CUSIP numbers for
                                 assignment to the Global Notes. Upon obtaining
                                 such additional CUSIP numbers, the Company will
                                 deliver a list of such additional numbers to
                                 the Trustee and DTC.

                                 maintained by the Trustee under the Indentures.
                                 The beneficial owner of a Global Note (or one
                                 or more indirect participants in DTC designated
                                 by such owner) will designate one or more
                                 participants in DTC (with respect to such Note,
                                 the "DTC participants") to act as agent for
                                 such beneficial owner in connection with the

                                 participants. The ownership interest of such
                                 beneficial owner in such Global Note will be
                                 recorded through the records of such DTC
                                 participants or through the separate records of
                                 such DTC participants and one or more indirect

                                 a Global Note will be accomplished by book
                                 entries made by DTC and, in turn, by DTC
                                 participants (and in certain cases, one or more
                                 indirect participants in DTC) acting on behalf
                                 of beneficial transferors and transferees of
                                 such Global Note.

Exchanges:                       The Trustee may deliver to DTC and the CUSIP
                                 Service Bureau at any time a written notice
                                 specifying (a) the CUSIP numbers of two or more

                                 Terms, as the case may be (other than Original
                                 Issue Dates), and for which interest has been
                                 paid to the same date; (b) a date, occurring at
                                 least 30 days after such written notice is
                                 delivered and at least 30 days before the next
                                 Interest Payment Date for the related Notes
                                 issued in book-entry form, on which such Global
                                 Notes shall be exchanged for a single
                                 replacement Global Note; and (c) a new CUSIP
                                 number, obtained from the Company, to be
                                 assigned to such replacement Global Note. Upon
                                 receipt of such a notice, DTC will send to its
                                 Participants (including the Trustee) a written

Failure to Settle:               If the Trustee fails to enter an SDFS deliver
                                 order with respect to a Note pursuant to
                                 Settlement Procedure F, the Trustee may deliver
                                 to DTC, through DTC's Participant Terminal
                                 System, as soon as practicable a withdrawal
                                 message instructing DTC to debit such Note to
                                 the participant account of the Trustee
                                 maintained at DTC. DTC will process the
                                 withdrawal message, provided that such
                                 participant account contains a principal amount
                                 of the Notes that is at least equal to the
                                 principal amount to be debited. If withdrawal
                                 messages are processed with respect to all the
                                 Notes evidenced by a Global Note, the Trustee
                                 will mark such Global Note "canceled", make
                                 appropriate entries in its records and send
                                 certificate of destruction of such canceled
                                 Global Note to the Company. The CUSIP number
                                 assigned to such Global Note shall, in
                                 accordance with CUSIP Service Bureau
                                 procedures, be canceled and not immediately
                                 reassigned. If withdrawal messages are
                                 processed with respect to a portion of the
                                 Notes represented by a single Global Note, the
                                 Trustee will exchange such Global Note for two
                                 Notes, one of which shall represent the Notes
                                 for which withdrawal messages are processed and

                                 shall be canceled immediately after issuance,
                                 and the other of which shall represent the
                                 other Notes previously represented by the
                                 surrendered Global Note and shall bear the
                                 CUSIP number of the surrendered Global Note.

                                 In the case of any Note sold through the
                                 Offering Agent, as agent, if the purchase price
                                 for any Note is not timely paid to the DTC
                                 participants with respect to such Note by the
                                 beneficial investor or other purchaser thereof
                                 (or a person, including an indirect participant
                                 in DTC, acting on behalf of such investor or
                                 other purchaser), such DTC participants and, in
                                 turn, the related Offering Agent may enter SDFS
                                 deliver orders through DTC's Participant
                                 Terminal System reversing the orders entered
                                 pursuant to Settlement Procedures F and G,
                                 respectively. Thereafter, the Trustee will
                                 deliver the withdrawal message and take the
                                 related actions described in the preceding
                                 paragraph. If such failure shall have occurred
                                 for any reason other than default by the
                                 applicable Offering Agent to perform its
                                 obligations hereunder or under the Distribution

                                 Original Issue Date of such Note for the first
                                 interest period or from the most recent
                                 Interest Payment Date (as defined below) to
                                 which interest has been paid or duly provided
                                 for all subsequent interest periods to, but
                                 excluding, the applicable Interest Payment
                                 Date, the Stated Maturity Date or, in the case
                                 of Remarketed Notes, the Interest Rate
                                 Adjustment Date, or the date of earlier
                                 redemption or repayment, as the case may be
                                 (the Stated Maturity Date or date of earlier
                                 redemption or repayment is referred to herein

                                 Each Remarketed Note initially will earn
                                 interest at the Initial Interest Rate for the
                                 Initial Interest Rate Period specified in the
                                 applicable Pricing Supplement. Thereafter,
                                 while a Remarketed Note is in the Short Term
                                 Rate Mode, it will earn interest during each
                                 Short Term Rate Period at fixed rates
                                 established by the applicable Remarketing Agent

                                 Term Rate Mode, it will earn interest during
                                 each Long Term Rate Period at fixed rates
                                 established prior to the commencement of such

                                 to any Note falls on a day that is not a
                                 Business Day, the required payment to be made
                                 on such day need not be made on such day, but
                                 may be made on the next succeeding Business Day
                                 with the same force and effect as if made on
                                 such day, and no interest shall accrue on such
                                 payment for the period from and after such day
                                 to the next succeeding Business Day. In the
                                 case of a Note bearing interest at a floating
                                 rate for which LIBOR is an applicable Interest
                                 Rate Basis, if such Business Day falls in the
                                 next succeeding calendar month, such Interest
                                 Payment Date will be the immediately preceding
                                 Business Day. If the Maturity Date with respect
                                 to any Note bearing interest at a floating rate
                                 falls on a day that is not a Business Day, the
                                 required payment to be made on such day need
                                 not be made on such day, but may be made on the
                                 next succeeding Business Day with the same
                                 force and effect as if made on such day, and no
                                 interest shall accrue on such payment for the
                                 period from and after the Maturity Date to the
                                 next succeeding Business Day. In case of
                                 Remarketed Notes, each Interest Rate Adjustment
                                 Date shall be a Business Day. "Business Day"
                                 means any day, other than a Saturday or Sunday,
                                 that is neither a legal holiday nor a day on

                                 required by law, regulation or executive order

                                 Dallas, Texas; provided, however, that, with
                                 respect to Notes as to which LIBOR is an
                                 applicable Interest Rate Basis, such day is
                                 also a London Business Day. "London Business
                                 Day" means a day on which dealings in the
                                 Designated LIBOR Currency are transacted in the

                                 periods) on Fixed Rate Notes, and Remarketed
                                 Notes bearing interest at a fixed rate during a
                                 Long Term Rate Period will be calculated and
                                 paid on the basis of a 360-day year of twelve
                                 30-day months. Interest (including payments for
                                 partial periods) on Remarketed Notes bearing
                                 interest at a fixed rate during a Short Term
                                 Rate Period will be calculated and paid on the
                                 basis of actual days elapsed over 360 (or over

                                 Rate Note will be calculated by multiplying its
                                 principal amount by an accrued interest factor.
                                 Such accrued interest factor is computed by
                                 adding the interest factor calculated for each
                                 day in the period for which accrued interest is
                                 being calculated. Unless otherwise provided in

                                 factor for each such day is computed by
                                 dividing the interest rate applicable to such

                                 Notes for which the interest rate is calculated
                                 with reference to two or more Interest Rate

         INDENTURE SUPPLEMENT NO. 3 ("Indenture Supplement"), dated as of
January 27, 2000, between CENTEX CORPORATION, a Nevada corporation (together
with its successors and assigns as provided in the Indenture referred to below,
the "Company"), and CHASE BANK OF TEXAS, NATIONAL ASSOCIATION, a national
banking 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 Senior Medium-Term Notes,
Series C (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 Fixed
Rate Note or Floating Rate Note attached hereto as Exhibits A and B,
respectively, either directly or by reference therein, shall have the meanings
assigned to them therein.

         As used in this Indenture Supplement, the following terms shall have
the following meanings:

AMORTIZED FACE AMOUNT:

         The term "Amortized Face Amount" of an Original Issue Discount Note, as
of the date that (i) the principal amount of such Note is to be repaid prior to
its Stated Maturity, whether upon declaration of acceleration, call for
redemption, repayment at the option of the Holder or otherwise, or (ii) any
consent, notice, request, direction, waiver or suit by the Noteholders shall be
deemed to be given, made or commenced under this Indenture, shall mean the
principal amount of such Note multiplied by its Issue Price plus the portion of
the difference between the dollar amount thus obtained and the principal amount
of such Note that has accreted at the Yield to maturity of such Note (computed
in accordance with generally accepted United States bond yield computation
principles) to such date, but in no event shall the Amortized Face Amount of an
Original Issue Discount Note exceed its principal amount stated in the
applicable Company Order.

AMORTIZING NOTE:

         The term "Amortizing Note" shall mean a Note for which payments of
principal of and interest on such Note are made in installments over the life of
such Note, and unless otherwise specified in the applicable Company Order,
payments with respect to an Amortizing Note shall be applied first to interest
due and payable thereon and then to the reduction of the unpaid principal amount
thereof.

AUTHORIZED AGENT:

         The term "Authorized Agent" shall mean an agent of the Company
designated by an Officers' Certificate to give to the Trustee the information
specified in clause (a) of "Company Order" for the issuance of a Note.

BASIS POINT:

         The term "Basis Point" shall mean one-one hundredth of a percentage
point.

CD RATE:

         The term "CD Rate" shall mean, with respect to any CD Rate Interest
Determination Date, the rate on such date for negotiable United States dollar
certificates of deposit having the Index Maturity specified in the applicable
Pricing Supplement as published in H.15(519) (as hereinafter defined) under the
heading "CDs (secondary market)" or, if not so published by 3:00 P.M., New York
City time, on the related Calculation Date, the rate on such CD Rate Interest
Determination Date for negotiable United States dollar certificates of deposit
of the Index Maturity specified in the applicable Pricing Supplement as
published in H.15 Daily Update (as hereinafter defined), or such other
recognized electronic source used for the purpose of displaying such rate, under
the caption "CDs (secondary market)." If such rate is not yet published in
H.15(519), H.15 Daily Update or another recognized electronic source by 3:00
P.M., New York City time, on the related Calculation Date, then the CD Rate on
such CD Rate Interest Determination Date will be calculated by the Calculation
Agent and will be the arithmetic mean of the secondary market offered rates as
of 10:00 A.M., New York City time, on such CD Rate Interest Determination Date,
of three leading nonbank dealers in negotiable United States dollar certificates
of deposit in The City of New York (which may include the Agents or their
affiliates) selected by the Calculation Agent for negotiable United States
dollar certificates of deposit of major United States money center banks for
negotiable certificates of deposit with a remaining maturity closest to the
Index Maturity specified in the applicable Pricing Supplement in an amount that
is representative for a single transaction in that market at that time;
provided, however, that if the dealers so selected by the Calculation Agent are
not quoting as mentioned in this sentence, the CD Rate determined as of such CD
Rate Interest Determination Date will be the CD Rate in effect on such CD Rate
Interest Determination Date.

CD RATE INTEREST DETERMINATION DATE:

         The term "CD Rate Interest Determination Date" shall mean the Interest
Determination Date relating to a Floating Rate Note for which the interest rate
is determined with reference to the CD Rate.

CMT RATE:

         The term "CMT Rate" shall mean, with respect to any CMT Rate Interest
Determination Date, the rate displayed on the Designated CMT Telerate Page under
the caption "...Treasury Constant Maturities...Federal Reserve Board Release
H.15...Mondays Approximately 3:45 P.M.," under the column for the Designated CMT
Maturity Index for (i) if the Designated CMT Telerate Page is 7051, the rate on
such CMT Rate Interest Determination Date and (ii) if the Designated CMT
Telerate Page is 7052, the weekly or monthly average, as specified in the
Company Order, for the week or the month, as applicable, ended immediately
preceding the week or the month, as applicable, in which the related CMT Rate
Interest Determination Date falls. If such rate is no longer displayed on the
relevant page or is not so displayed by 3:00 P.M., New York City time, on the
related Calculation Date, then the CMT Rate for such CMT Rate



                                      -3-
<PAGE>   4



Interest Determination Date will be such treasury constant maturity rate for the
Designated CMT Maturity Index as published in H.15(519). If such rate is no
longer published or is not so published by 3:00 P.M., New York City time, on the
related Calculation Date, then the CMT Rate on such CMT Rate Interest
Determination Date will be such treasury constant maturity rate for the
Designated CMT Maturity Index (or other United States Treasury rate for the
Designated CMT Maturity Index) for the CMT Rate Interest Determination Date with
respect to such Interest Reset Date as may then be published by either the Board
of Governors of the Federal Reserve System or the United States Department of
the Treasury that the Calculation Agent determines to be comparable to the rate
formerly displayed on the Designated CMT Telerate Page and published in
H.15(519). If such information is not so provided by 3:00 P.M., New York City
time, on the related Calculation Date, then the CMT Rate on the CMT Rate
Interest Determination Date will be calculated by the Calculation Agent and will
be a yield to maturity, based on the arithmetic mean of the secondary market
offered rates as of approximately 3:30 P.M., New York City time, on such CMT
Rate Interest Determination Date reported, according to their written records,
by three leading primary United States government securities dealers in The City
of New York (which may include the Agents or their affiliates) (each, a
"Reference Dealer") selected by the Calculation Agent (from five such Reference
Dealers selected by the Calculation Agent and eliminating the highest quotation
(or, in the event of equality, one of the highest) and the lowest quotation (or,
in the event of equality, one of the lowest)), for the most recently issued
direct noncallable fixed rate obligations of the United States ("Treasury
Notes") with an original maturity of approximately the Designated CMT Maturity
Index and a remaining term to maturity of not less than such Designated CMT
Maturity Index minus one year. If the Calculation Agent is unable to obtain
three such Treasury Note quotations, the CMT Rate on such CMT Rate Interest
Determination Date will be calculated by the Calculation Agent and will be a
yield to maturity based on the arithmetic mean of the secondary market offered
rates as of approximately 3:30 P.M., New York City time, on such CMT Rate
Interest Determination Date of three Reference Dealers in The City of New York
(from five such Reference Dealers selected by the Calculation Agent and
eliminating the highest quotation (or, in the event of equality, one of the
highest) and the lowest quotation (or, in the event of equality, one of the
lowest)), for Treasury Notes with an original maturity of the number of years
that is the next highest to the Designated CMT Maturity Index and a remaining
term to maturity closest to the Designated CMT Maturity Index and in an amount
of at least $100 million. If three or four (and not five) of such Reference
Dealers are quoting as described above, then the CMT Rate will be based on the
arithmetic mean of the offered rates obtained and neither the highest nor the
lowest of such quotes will be eliminated; provided, however, that if fewer than
three Reference Dealers so selected by the Calculation Agent are quoting as
mentioned herein, the CMT Rate determined as of such CMT Rate Interest
Determination Date will be the CMT Rate in effect on such CMT Rate Interest
Determination Date. If two Treasury Notes with an original maturity as described
in the second preceding sentence have remaining terms to maturity equally close
to the Designated CMT Maturity Index, the Calculation Agent will obtain
quotations for the Treasury Note with the shorter remaining term to maturity.

Rate Interest Determination Date for commercial paper having the Index Maturity

published in H.15(519), H.15 Daily Update or another recognized electronic
source by 3:00 P.M., New York City time, on the related Calculation Date, then
the Commercial Paper Rate on such Commercial Paper Rate Interest Determination
Date will be calculated by the Calculation Agent and will be the Money Market
Yield of the arithmetic mean of the offered rates at approximately 11:00 A.M.,
New York City time, on such Commercial Paper Rate Interest Determination Date of

         that such Lien attaches to such asset concurrently with or within 180
         days after the acquisition thereof or the making of such improvement;

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

             (viii) Any Lien arising out of the refinancing, extension, renewal
         or replacement of any of the Liens permitted by any of clauses (i)
         through (vii) above; provided that such Indebtedness is not increased
         and is not secured by any additional assets; and

             (ix) any Lien imposed by law.

         (b) Notwithstanding the provisions of subsection (a) of this Section
3.01, the Company or any subsidiary may issue, assume or guarantee indebtedness
for borrowed money 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).

         Section 3.02. Limitation on Sale and Lease-Back Transactions. The
Company will not, nor will it permit any subsidiary 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 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 so leased, (b) the Company or such subsidiary would be entitled
to incur Indebtedness secured by a Lien on the property to be leased pursuant to
Section 3.01, (c) the Company shall, and in any such case



                                      -22-
<PAGE>   23



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 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 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.

         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:



                                      -23-
<PAGE>   24



         (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 or sinking funds 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 and said sinking fund 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.

         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 Section 8.06, 13.04 and 13.05 of the Indenture
shall survive.

                                  ARTICLE FIVE

                                  Miscellaneous

         Section 5.01. Ratification of Indenture. As supplemented by this
Indenture Supplement, the Indenture is in all respects ratified and confirmed
and the Indenture as so supplemented by this Indenture Supplement shall be read,
taken and construed as one and the same instrument.

         Section 5.02. Conflict with Trust Indenture Act. If any provision
hereof limits, qualifies or conflicts with another provision hereof which is
required to be included in this Indenture Supplement by any of the provisions of
the Trust Indenture Act, such required provisions shall control.

         Section 5.03. Effect of Headings. The article and section headings
herein are included for convenience only and shall not affect the construction
hereof.

         Section 5.04. Counterparts. This Indenture Supplement may be executed
in any number of counterparts, each of which shall be an original; but such
counterparts shall together constitute but one and the same instrument.



                                      -24-
<PAGE>   25



         Section 5.05. Severability. In case any provision of this Indenture
Supplement or in the Senior Notes shall be found invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         Section 5.06. Benefits of Indenture Supplement. Nothing in this
Indenture Supplement or in the Notes, express or implied, shall give to any
Person, other than the parties hereto and their successors hereunder and the
Holders, any benefit or any legal or equitable right, remedy or claim under this
Indenture Supplement.

         Section 5.07. Acceptance of Trusts. Chase Bank of Texas, National
Association hereby accepts the trusts in this Indenture Supplement declared and
provided, upon the terms and conditions herein and in the Indenture set forth.

         Section 5.08. Governing Law. This Indenture Supplement and each Note
issued hereunder shall be deemed to be a contract made under the laws of the
State of Texas, and for all purposes shall be construed in accordance with the
laws of said State.

         Section 5.09. Compliance with Law. It is the intent of the Company and
the Holders of the Notes to conform to and contract in strict compliance with
applicable usury law from time to time in effect. All agreements between the
Holders of the Notes and the Company are hereby limited by the provisions of
this Section 5.09 which shall override and control all such agreements, whether
now existing or hereafter arising and whether written or oral. In no way, nor in
any event or contingency (including but not limited to prepayment, default,
demand for payment, or acceleration of the maturity of any obligation), shall
the interest taken, reserved, contracted for, charged or received under this
Indenture Supplement or the Notes or otherwise, exceed the Highest Lawful Rate.
If, from any possible construction of any document, interest would otherwise be
payable in excess of the Highest Lawful Rate, any such construction shall be
subject to the provisions of this Section 5.09 and such document shall be
automatically reformed and the interest payable shall be automatically reduced
to the Highest Lawful Rate, without the necessity of execution of any amendment
or new document. If the Holders shall ever receive anything of value which is
characterized as interest under applicable law and which would apart from this
provision be in excess of the Highest Lawful Rate, an amount equal to the amount
which would have been excessive interest shall, without penalty, be applied to
the reduction of the principal amount owing on the Notes in the inverse order of
its maturity and not to the payment of interest, or refunded to the Company if
and to the extent such amount which would have been excessive exceeds such
unpaid principal. The right to accelerate the maturity of the Notes does not
include the right to accelerate any interest which has not otherwise accrued on
the date of such acceleration, and the Holders do not intend to charge or
receive any unearned interest in the event of acceleration. All interest paid or
agreed to be paid to the Holders shall, to the extent permitted by applicable
law, be amortized, prorated, allocated and spread throughout the full stated
term (including any renewal or extension) of the Notes so that the amount of
interest on account of the Notes does not exceed the Highest Lawful Rate.

         The Company, for value received, hereby promises to pay to Cede & Co.,

<PAGE>   29


Date, begin to accrue for that part of the principal amount to which such
Original Issue Date is applicable) specified above, or from and including the
most recent Interest Payment Date specified above to which interest has been
paid or duly provided for, as the case may be. Interest shall be paid in arrears
semiannually on each Interest Payment Date in each year commencing on (a) the
first such Interest Payment Date next succeeding the earliest Original Issue
Date or Dates, or (b) if such Original Issue Date is after a Record Date and
prior to the first Interest Payment Date, on the second Interest Payment Date,
at a rate per annum from time to time equal to the lesser of (i) the Highest
Lawful Rate (as defined in the Indenture) or (ii) the per annum Interest Rate
set forth above until Maturity and the principal hereof is paid or made
available for payment. The interest so payable and punctually paid or duly
provided for on any Interest Payment Date will, as provided in the Indenture, be
paid to the Person in whose name this Senior Note is registered at the close of
business on the Record Date specified above next preceding such Interest Payment
Date; PROVIDED, HOWEVER, that if an Original Issue Date falls between a Record
Date and the next Interest Payment Date, the first payment of interest with
respect to such Original Issue Date will be made on the second Interest Payment
Date subsequent to such Original Issue Date to the Person in whose name this
Senior Note is registered at the close of business on the Record Date for such
second Interest Payment Date; and PROVIDED, FURTHER, that interest payable on
the Maturity Date or, if applicable, upon redemption, shall be payable to the
Person to whom principal shall be payable. Except as otherwise provided in the
Indenture, any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Record Date and shall be
paid to the Person in whose name this Senior Note is registered at the close of
business on a Record Date for the payment of such defaulted interest to be fixed
by the Company, notice whereof shall be given to Senior Noteholders not less
than fifteen calendar days prior to such Record Date. Payment of the principal

10:30 A.M., New York City time or such other time as shall be agreed upon
between the Trustee and the Depositary, on the day on which such payment is due,
by wire transfer into the account specified by the Depositary; PROVIDED,
HOWEVER, that as a condition to the payment at the Maturity Date of any part of
the principal and any applicable premium of this Global Senior Note, the
Depositary shall surrender, or cause to be surrendered, this Global Senior Note
to the Trustee. The Company will pay any administrative costs imposed by banks
in connection with making payments by wire transfer, but not any tax, assessment
or governmental charge imposed on the Holder of this Senior Note.

in whole or from time to time in part for a definitive individual Senior Note
or Senior Notes, with the same Original Issue Date or Dates, Maturity Date,
Interest Rate and redemption and other provisions as provided herein or in the
Indenture.

         The Indenture and the Senior Notes shall be governed by, and construed
in accordance with, the laws of the State of Texas.

                   [REVERSE OF GLOBAL SENIOR FIXED RATE NOTE]

                               CENTEX CORPORATION
                  SENIOR FIXED RATE MEDIUM-TERM NOTE, SERIES C

         This Global Senior Note is one of, and a global security which
represents Senior Notes which are part of, a duly authorized issue of Senior
Debt Securities of the Company (herein called the "Senior Notes"), issued and
to be issued in one or more Series under an Indenture dated as of October 1,
1998 (herein called the "Senior Indenture") between the Company and Chase Bank
of Texas, National Association, as Trustee (herein called the "Trustee," which
term includes any successor Trustee under the Senior Indenture), to which
Senior Indenture and all indentures supplemental thereto (including the
Indenture Supplement dated as of January ___, 2000 which authorizes the Senior
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 Senior Noteholders, and of the terms upon which the Senior
Notes are, and are to be, authenticated and delivered. All terms used in this
Senior Note which are defined in the Senior Indenture or in any indenture
supplemental thereto but are not defined in this Senior Note shall have the
meanings assigned to them in the Senior Indenture or in any indenture
supplemental thereto.

         Each Senior Note shall be dated the date of its authentication by the
Trustee. Each Senior Note shall also bear an Original Issue Date or Dates which
with respect to this Global Senior Note (or any portion thereof) shall mean the
date or dates of the original issue of the Senior Notes represented hereby as
specified on the face hereof, and such Original Issue Date or Dates shall
remain the same for all Senior Notes subsequently issued upon transfer,
exchange or substitution of such original Senior Note (or such subsequently
issued Senior Notes) regardless of their dates of authentication. The Senior
Notes may bear different dates, mature at different times, bear interest at
different rates, be subject to different redemption provisions, if any, and may
otherwise vary, all as provided in the Senior Indenture.

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

         Interest on this Senior Note will be payable on the Interest Payment
Date or Interest Payment Dates as specified on the face hereof and, in either
case, at Maturity. Unless otherwise specified on the face hereof, payments on
this Senior Note with respect to any particular Interest Payment Date or the
Maturity Date will include interest accrued from and including the applicable
Original Issue Date, 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 Senior
Note will be computed and paid on the basis of a 360-day year of twelve 30-day
months.

         Unless otherwise specified on the face hereof or the Company Order, if
this Senior Note is an Amortizing Note, payments with respect to this Senior
Note will be applied first to interest due and payable hereon and then to the
reduction of the unpaid principal amount hereof. If this Senior Note is an
Amortizing Note, a table setting forth the schedule of dates and amounts of
payments of principal of and interest on this Senior Note or the formula for
the amortization of principal and/or interest is set forth in an annex attached
to this Senior Note.

         All percentages resulting from any calculation with respect to this
Senior Note will be rounded, if necessary, to the nearest one
hundred-thousandth of a percentage point (with five one-millionths of a
percentage point rounded upward) and all dollar or foreign or composite
currency amounts used in or resulting from any such calculation with respect to
this Senior Note will be rounded, in the case of United States dollars, to the
nearest cent or, in the case of a foreign or composite currency, to the nearest
unit (with one-half cent or unit being rounded upward).

         If an Interest Payment Date or the Maturity Date for this Senior 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 Senior 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.

         This Senior Note will be redeemable at the option of the Company prior
to its Stated Maturity Date only if an Initial Redemption Date is specified on
the face hereof. If so specified, this Senior Note will be subject to redemption
at the option of the Company on any date on and after such Initial Redemption
Date in whole or from time to time in part in increments of $1,000 or any other
integral multiple thereof, at the redemption prices specified in an annex
attached to this Senior Note, plus accrued and unpaid interest to but excluding
the date of redemption, but payments due with respect to this Senior Note prior
to the date of redemption will be payable to the Holder of this Senior Note of
record at the close of business on the relevant Record Date specified on the
face hereof, all as provided in the Senior Indenture. Notice of such redemption
shall be given by mailing by first-class mail a notice of such redemption not
less than 20 nor more than 60 calendar days prior to the date fixed for
redemption to the Holder of this Senior Note, in accordance with the provisions
of the Senior Indenture. In the event of redemption of this Senior Note in part
only, this Senior Note will be canceled and a new Senior Note or Senior Notes
representing the unredeemed portion hereof will be issued in the name of the
Holder hereof. This Senior Note is not subject to a sinking fund unless
otherwise specified in an annex attached hereto.

         If so specified on the face of this Senior Note, (i) this Senior Note
shall be subject to repayment, in whole or in part, prior to the Stated
Maturity Date at the option of the Holder on a certain date or dates and at a
certain price or prices, plus accrued and unpaid interest to but excluding the
date of payment; and/or (ii) the Interest Rate specified on the face hereof may
be reset by the Company in accordance with a formula or otherwise on the
Optional Interest Reset Date or Dates specified on the face hereof.

         Notwithstanding anything herein to the contrary, if this Senior Note
is an Original Issue Discount Note as specified on the face hereof, the amount
payable in the event the principal amount hereof is declared to be due and
payable immediately by reason of an Event of Default or in the event of
redemption or repayment hereof prior to the Stated Maturity hereof, in lieu of
the principal amount due at the Stated Maturity hereof, shall be the Amortized
Face Amount of this Senior Note as of the date of declaration, redemption or
repayment, as the case may be. The "Amortized Face Amount" of this Senior Note
shall be the amount equal to the principal amount of this Senior Note
multiplied by the Issue Price specified on the face hereof plus (b) the portion
of the difference between the dollar amount thus obtained and the principal
amount hereof that has accreted at the Yield to Maturity specified on the face
hereof (computed in accordance with generally accepted United States bond yield
computation principles) to such date of declaration, redemption or repayment
but in no event shall the Amortized Face Amount of this Senior Note exceed the
principal amount stated on the face hereof.

         In case an Event of Default shall have occurred and be continuing with
respect to the Senior 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 Senior Indenture. The Senior
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
Senior Notes then outstanding. An Event of Default with respect to the Senior
Debt Security of any other Series issued under the Senior Indenture, including
the failure to make any payment of principal or interest with respect thereto
when and as due, will not be an Event of Default with respect to the Senior
Notes.

         The Senior Indenture 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 Senior Notes at the time outstanding,
evidenced as in the Senior Indenture provided, to execute supplemental
indentures adding any provisions to or changing in any manner or eliminating
any of the provisions of the Senior Indenture or of any supplemental indenture
or modifying in any manner the rights of the Holders of the Senior Notes;
PROVIDED, HOWEVER, that no such supplemental indenture shall (i) extend the
fixed maturity of any Senior 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 Senior Note so affected, or (ii) reduce the aforesaid percentage
of Senior Notes, the consent of the Holders of which is required for any such
supplemental indenture, without the consent of the Holders of all Senior Notes
then outstanding. It is also provided in the Senior Indenture that the Holders
of a majority in aggregate principal amount of the Senior Notes at the time
outstanding may on behalf of the Holders of all the Senior Notes waive any past
default under the Senior Indenture and its consequences, except a default in
the payment of the principal of or premium, if any, or interest on any of the
Senior Notes. Any such consent or waiver by the Holder of this Global Senior
Note (unless revoked as provided in the Senior Indenture) shall be conclusive
and



                                       5
<PAGE>   33


binding upon such Holder and upon all future Holders and owners of this Global
Senior Note and of any Senior Note issued in exchange or substitution herefor,
whether or not any notation of such consent or waiver is made upon this Global
Senior Note.

         As set forth in, and subject to, the provisions of the Senior
Indenture, no Holder of any Senior Notes will have any right to institute any
proceeding with respect to the Senior Indenture or for any remedy thereunder,
unless such Holder shall have previously given to the Trustee written notice of
default in respect of the Senior Notes and the continuance thereof, and unless
the Holders of not less than 25 percent in aggregate principal amount of the
Senior 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 the enforcement of payment of the
principal of and any premium or interest on this Global Senior Note on or after
the respective due dates expressed herein.

         THIS SENIOR NOTE IS A GLOBAL SENIOR NOTE REGISTERED IN THE NAME OF THE
DEPOSITARY OR A NOMINEE THEREOF AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE
OR IN PART FOR THE INDIVIDUAL NOTES REPRESENTED HEREBY, THIS GLOBAL SENIOR NOTE
MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE
DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER
NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A
SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.

         If at any time the Depositary for this Global Senior Note notifies the
Company that it is unwilling or unable to continue as Depositary for this
Global Senior Note or if at any time the Depositary for this Global Senior Note
shall no longer be registered as a clearing agency under the Securities
Exchange Act of 1934, as amended, or any successor statute or regulation, the
Company may appoint a successor Depositary with respect to this Global Senior
Note. If (A) a successor Depositary for this Global Senior Note is not
appointed by the Company within 60 calendar days after the Company receives
such notice or becomes aware of such ineligibility, or (B) any Senior Notes are
represented by this Global Senior Note at a time when an Event of Default with
respect to the Senior Notes shall have occurred and be continuing, then in each
case the Company's election to issue this Senior Note in global form shall no
longer be effective with respect to this Global Senior Note and the Company
will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of individual Senior Notes in exchange for this
Global Senior Note, shall authenticate and make available for delivery,
individual Senior Notes of like tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of this Global Senior
Note in exchange for this Global Senior Note.

         If agreed by the Company and the Depositary with respect to Senior
Notes issued in the form of this Global Senior Note, the Depositary for such
Global Senior Note shall surrender this Global Senior Note in exchange in whole
or in part for individual Senior Notes of like tenor and terms in definitive
form on such terms as are acceptable to the Company and such Depositary.
Thereupon the Company shall execute, and the Trustee shall authenticate and
make available for delivery, without a service charge, (1) to each Person
specified by such Depositary, a new Senior Note or Senior Notes of like tenor
and terms, and of any authorized denominations as requested by such Person in
aggregate principal amount equal to and in exchange for the beneficial interest
of such Person in this Global Senior Note, and (2) to such Depositary a new
Global Senior Note of like tenor and terms and in a denomination equal to the
difference, if any, between the principal amount of this Global Senior Note and
the aggregate principal amount of Senior Notes delivered to Holders thereof.

         Under certain circumstances specified in the Senior Indenture, the
Depositary may be required to surrender any two or more Global Senior Notes
which have identical terms (but which may have differing Original Issue Dates)
to the Trustee, and the Company shall execute and the Trustee shall
authenticate and deliver to, or at the direction of, the Depositary a Global
Senior Note in principal amount equal to the aggregate principal amount of, and
with all terms identical to, the Global Senior Notes surrendered to the
Trustee, and such new Global Senior Note shall indicate each applicable
Original Issue Date and the principal amount applicable to each such Original
Issue Date.

         No reference herein to the Senior Indenture and no provision of this
Global Senior Note or of the Senior 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 Global Senior Note at the
times, places and rates, and in the coin or currency, herein prescribed.

         The Senior Indenture contains provisions for the satisfaction and
discharge of the Senior Indenture upon compliance by the Company with certain
conditions specified therein, which provisions apply to this Senior Note.

         The Company, the Trustee, any paying agent and any Senior Debt
Security Registrar (as defined in the Senior Indenture) for the Senior Notes
may deem and treat the Holder hereof as the absolute owner of this Global
Senior Note (whether or not this Global Senior 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 Global Senior Note, or for any claim
based hereon or otherwise in respect hereof, or based on or in respect of the
Senior 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.

         It is the intent of the Company and the Holders of this Senior Note to
conform to and contract in strict compliance with applicable usury law from
time to time in effect. All agreements between the Holders of this Senior Note
and the Company are hereby limited by the provisions of this paragraph which
shall override and control all such agreements, whether now existing or
hereafter arising and whether written or oral. In no way, nor in any event or
contingency (including but not limited to prepayment, default, demand for
payment, or acceleration of the maturity of any obligation), shall the interest
taken, reserved, contracted for, charged or received under this Senior Note or
otherwise exceed the Highest Lawful Rate. If, from any possible construction of
any document, interest would otherwise be payable in excess of the Highest
Lawful Rate, any such construction shall be subject to the provisions of this
paragraph and such document shall be automatically reformed and the interest
payable shall be automatically reduced to the Highest Lawful Rate, without the
necessity of execution of any amendment or new document. If the Holders of this
Senior Note shall ever receive anything of value which is characterized as
interest under applicable law and which would apart from this provision be in
excess of the Highest Lawful Rate, an amount equal to the amount which would
have been excessive interest shall, without penalty, be applied to the
reduction of the principal amount owing on this Senior Note in the inverse
order of its maturity and not to the payment of interest, or refunded to the
Company if and to the extent such amount which would have been excessive
exceeds such unpaid principal. The right to accelerate the maturity of this
Senior Note does not include the right to accelerate any interest which has not
otherwise accrued on the date of such acceleration, and the Holders of this
Senior Note do not intend to charge or receive any unearned interest in the
event of acceleration. All interest paid or agreed to be paid to the Holders of
this Senior Note shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full stated term
(including any renewal or extension) of this Senior Note so that the amount of
interest on account of this Senior Note does not exceed the Highest Lawful
Rate.

for payment of public and private debts, on the Stated Maturity Date specified
above and to pay interest thereon, in such coin or currency, from and including
the Original Issue Date (or if this Global Senior Note has two or more Original
Issue Dates, interest shall, beginning on each such Original Issue Date, begin

Date is applicable) specified above, or from and including the most recent
Interest Payment Date specified above to which interest has been paid or duly
provided for, as the case may be. Interest shall be paid in arrears monthly,
quarterly, semiannually or annually as specified above under Interest Payment
Dates, on each Interest Payment Date in each year and at Maturity, commencing on
(a) the first such Interest Payment Date next succeeding the earliest Original

Date, at a rate per annum from time to time equal to the lesser of (i) the
Highest Lawful Rate (as defined in the Indenture) or (ii) the Initial Interest
Rate specified above until the initial Interest Reset Date specified above, and
thereafter at a rate per annum determined in accordance with the provisions in
the Indenture for calculating the Interest Rate for Senior Notes having the
Interest Rate Basis specified above, until Maturity and the principal hereof is
paid or made available for payment. The interest so payable and punctually paid
or duly provided for on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Senior Note is registered at
the close of business on the Record Date specified above next preceding such
Interest Payment Date; PROVIDED, HOWEVER, that if an Original Issue Date falls
between a Record Date and the next Interest Payment Date, the first payment of
interest with respect to such Original Issue Date will be made on the second
Interest Payment Date subsequent to such Original Issue Date to the Person in
whose name this Senior Note is registered at the close of business on the Record
Date for such second Interest Payment Date; and PROVIDED, FURTHER, that interest
payable on the Maturity Date or, if applicable, upon redemption, shall be
payable to the Person to whom principal shall be payable. Except as otherwise
provided in the Indenture, any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Record
Date and shall be paid to the Person in whose name this Senior Note is
registered at the close of business on a Record Date for the payment of such
defaulted interest to be fixed by the Company, notice whereof shall be given to
Senior Noteholders not less than fifteen calendar days prior to such Record
Date. Payment of the principal of and any premium and interest on this Senior
Note shall be made on or before 10:30 A.M., New York City time or such other
time as shall be agreed upon between the Trustee and the Depositary, on the day
on which such payment is due, by wire transfer into the account specified by the
Depositary; PROVIDED, HOWEVER, that as a condition to the payment at the
Maturity Date of any part of the principal and any applicable premium of this
Global Senior Note, the Depositary shall surrender, or cause to be surrendered,
this Global Senior Note to the Trustee. The Company will pay any administrative
costs imposed by banks in connection with making payments by wire transfer, but
not any tax, assessment or governmental charge imposed on the Holder of this
Senior Note.

                  [REVERSE OF GLOBAL SENIOR FLOATING RATE NOTE]

                               CENTEX CORPORATION
                 SENIOR FLOATING RATE MEDIUM-TERM NOTE, SERIES C

         This Global Senior Note is one of, and a global security which
represents Senior Notes which are part of, a duly authorized issue of Senior
Debt Securities of the Company (herein called the "Senior Notes"), issued and to
be issued in one or more Series under an Indenture dated as of October 1, 1998
(herein called the "Senior Indenture") between the Company and Chase Bank of
Texas, National Association, as Trustee (herein called the "Trustee," which term
includes any successor Trustee under the Senior Indenture), to which Senior
Indenture and all indentures supplemental thereto (including the Indenture
Supplement dated as of January ___, 2000 which authorizes the Senior 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
Senior Noteholders, and of the terms upon which the Senior Notes are, and are to
be, authenticated and delivered. All terms used in this Senior Note which are
defined in the Senior Indenture or in any indenture supplemental thereto but are
not defined in this Senior Note shall have the meanings assigned to them in the
Senior Indenture or in any indenture supplemental thereto.

         Each Senior Note shall be dated the date of its authentication by the
Trustee. Each Senior Note shall also bear an Original Issue Date or Dates which
with respect to this Global Senior Note (or any portion thereof) shall mean the
date or dates of the original issue of the Senior Notes represented hereby as
specified on the face hereof, and such Original Issue Date or Dates shall remain
the same for all Senior Notes subsequently issued upon transfer, exchange or
substitution of such original Senior Note (or such subsequently issued Senior
Notes) regardless of their dates of authentication. The Senior Notes may bear
different dates, mature at different times, bear interest at different rates, be
subject to different redemption provisions, if any, and may otherwise vary, all
as provided in the Senior Indenture.

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

         Interest on this Senior Note will be payable on the Interest Payment
Date or Interest Payment Dates as specified on the face hereof and, in either
case, at Maturity. Unless otherwise specified on the face hereof, payments on
this Senior Note with respect to any particular Interest Payment Date or the
Maturity Date will include interest accrued from and including the applicable
Original Issue Date, 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 Senior
Note shall be calculated for each day during such period by dividing the
interest rate applicable to such day by 360, if the Interest Rate Basis
specified on the face hereof is the CD Rate, the Commercial Paper Rate, the
Eleventh District Cost of Funds Rate, the Federal Funds Rate, LIBOR or the Prime
Rate, or by the actual number of days in the year, if the Interest Rate Basis
specified on the face hereof is the CMT Rate or the Treasury Rate. Unless
otherwise provided in an annex attached hereto, the Trustee, acting in the
capacity of Calculation Agent, will calculate the Interest Rate on this Senior
Note. Upon the request of any Holder of this Senior Note, the Trustee shall
provide to such Holder the Interest Rate then in effect and, if then determined,
the interest rate that will become effective on the next Interest Reset Date
with respect to this Senior Note. Each such determination of an Interest Rate
will be final and binding in the absence of manifest error.

         Unless otherwise specified in an annex attached hereto, if this Senior
Note is an Amortizing Note, payments with respect to this Senior Note will be
applied first to interest due and payable hereon and then to the reduction of
the unpaid principal amount hereof. If this Senior Note is an Amortizing Note, a
table setting forth the schedule of dates and amounts of payments of principal
of and interest on this Senior Note or the formula for the amortization of
principal and/or interest is set forth in an annex attached to this Senior Note.

         All percentages resulting from any calculation with respect to this
Senior Note will be rounded, if necessary, to the nearest one hundred-thousandth
of a percentage point (with five one-millionths of a percentage point rounded
upward) and all dollar or foreign or composite currency amounts used in or
resulting from any such calculation with respect to this Senior Note will be
rounded, in the case of United States dollars, to the nearest cent or, in the
case of a foreign or composite currency, to the nearest unit (with one-half cent
or unit being rounded upwards).



                                       5
<PAGE>   42


         If an Interest Payment Date or Maturity for this Senior 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 Senior 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. Notwithstanding the foregoing, in the case LIBOR is the
applicable Interest Rate Basis with respect to this Senior Note and the next
succeeding Business Day falls in the next succeeding calendar month, payment of
interest to be made on such day with respect to this Senior Note will be made on
the immediately preceding Business Day.

         This Senior Note will be redeemable at the option of the Company prior
to its Stated Maturity Date only if an Initial Redemption Date is specified on
the face hereof. If so specified, this Senior Note will be subject to redemption
at the option of the Company on any date on and after such Initial Redemption
Date in whole or from time to time in part in increments of $1,000 or any other
integral multiple thereof, at the redemption prices specified in an annex
attached to this Senior Note, plus accrued and unpaid interest to but excluding
the date of redemption, but payments due with respect to this Senior Note prior
to the date of redemption will be payable to the Holder of this Senior Note of
record at the close of business on the relevant Record Date specified on the
face hereof, all as provided in the Senior Indenture. Notice of such redemption
shall be given by mailing by first-class mail a notice of such redemption not
less than 20 nor more than 60 calendar days prior to the date fixed for
redemption to the Holder of this Senior Note, in accordance with the provisions
of the Senior Indenture. In the event of redemption of this Senior Note in part
only, this Senior Note will be canceled and a new Senior Note or Senior Notes
representing the unredeemed portion hereof will be issued in the name of the
Holder hereof. This Senior Note is not subject to a sinking fund unless
otherwise specified in an annex attached hereto.

         If so specified on the face of this Senior Note, (i) this Senior Note
shall be subject to repayment, in whole or in part, prior to Stated Maturity
Date at the option of the Holder on a certain date or dates and at a certain
price or prices, plus accrued and unpaid interest to but excluding the date of
payment; and/or (ii) the interest rate specified on the face hereof may be reset
by the Company in accordance with a formula or otherwise on the Optional
Interest Reset Date or Dates specified on the face hereof.

         In case an Event of Default shall have occurred and be continuing with
respect to the Senior 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 Senior Indenture. The Senior 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 Senior
Notes then outstanding. An Event of Default with respect to the Senior Debt
Security of any other Series issued under the Senior Indenture, including the
failure to make any payment of principal or interest with respect thereto when
and as due, will not be an Event of Default with respect to the Senior Notes.

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

         As set forth in, and subject to, the provisions of the Senior
Indenture, no Holder of any Senior Notes will have any right to institute any
proceeding with respect to the Senior Indenture or for any remedy thereunder,
unless such Holder shall have previously given to the Trustee written notice of
default in respect of the Senior Notes and of the continuance thereof, and
unless the Holders of not less than 25 percent in aggregate principal amount of
the Senior 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 the enforcement of payment of the
principal of and any premium or interest on this Global Senior Note on or after
the respective due dates expressed herein.

         THIS SENIOR NOTE IS A GLOBAL SENIOR NOTE REGISTERED IN THE NAME OF THE
DEPOSITARY OR A NOMINEE THEREOF AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE
OR IN PART FOR THE INDIVIDUAL SENIOR NOTES REPRESENTED HEREBY, THIS GLOBAL
SENIOR NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A
NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR
ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A
SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.

         If at any time the Depositary for this Global Senior Note notifies the
Company that it is unwilling or unable to continue as Depositary for this Global
Senior Note or if at any time the Depositary for this Global Senior Note shall
no longer be registered as a clearing agency under the Securities Exchange Act
of 1934, as amended, or any successor statute or regulation, the Company may
appoint a successor Depositary with respect to this Global Senior Note. If (A) a
successor Depositary for this Global Senior Note is not appointed by the Company
within 60 calendar days after the Company receives such notice or becomes aware
of such ineligibility, or (B) any Senior Notes are represented by this Global
Senior Note at a time when an Event of Default with respect to the Senior Notes
shall have occurred and be continuing, then in each case the Company's election
to issue this Senior Note in global form shall no longer be effective with
respect to this Global Senior Note and the Company will execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
individual Senior Notes in exchange for this Global Senior Note, shall
authenticate and make available for delivery, individual Senior Notes of like
tenor and terms in definitive form in an aggregate principal amount equal to the
principal amount of this Global Senior Note in exchange for this Global Senior
Note.

         If agreed by the Company and the Depositary with respect to Senior
Notes issued in the form of this Global Senior Note, the Depositary for such
Global Senior Note shall surrender this Global Senior Note in exchange in whole
or in part for individual Senior Notes of like tenor and terms in definitive
form on such terms as are acceptable to the Company and such Depositary.
Thereupon the Company shall execute, and the Trustee shall authenticate and make
available for delivery, without a service charge, (1) to each Person specified
by such Depositary, a new Senior Note or Senior Notes of like tenor and terms,
and of any authorized denominations as requested by such Person in aggregate
principal amount equal to and in exchange for the beneficial interest of such
Person in this Global Senior Note, and (2) to such Depositary a new Global
Senior Note of like tenor and terms and in a denomination equal to the
difference, if any, between the principal amount of this Global Senior Note and
the aggregate principal amount of Senior Notes delivered to Holders thereof.

         Under certain circumstances specified in the Senior Indenture, the
Depositary may be required to surrender any two or more Global Senior Notes
which have identical terms (but which may have differing Original Issue Dates)
to the Trustee, and the Company shall execute and the Trustee shall authenticate
and deliver to, or at the direction of, the Depositary a Global Senior Note in
principal amount equal to the aggregate principal amount of, and with all terms
identical to, the Global Senior Notes surrendered to the Trustee, and such new
Global Senior Note shall indicate each applicable Original Issue Date and the
principal amount applicable to each such Original Issue Date.

         No reference herein to the Senior Indenture and no provision of this
Global Senior Note or of the Senior 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 Global Senior Note at the
times, places and rates, and in the coin or currency, herein prescribed.

         The Senior Indenture contains provisions for the satisfaction and
discharge of the Senior Indenture upon compliance by the Company with certain
conditions specified therein, which provisions apply to this Senior Note.

         The Company, the Trustee, any paying agent and any Senior Debt Security
Registrar (as defined in the Senior Indenture) for the Senior Notes may deem and
treat the Holder hereof as the absolute owner of this Global Senior Note
(whether or not this Global Senior 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 Global Senior Note, or for any claim based
hereon or otherwise in respect hereof, or based on or in respect of the Senior
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.

         It is the intent of the Company and the Holders of this Senior Note to
conform to and contract in strict compliance with applicable usury law from time
to time in effect. All agreements between the Holders of this Senior Note and
the Company are hereby limited by the provisions of this paragraph which shall
override and control all such agreements, whether now existing or hereafter
arising and whether written or oral. In no way, nor in any event or contingency
(including but not limited to prepayment, default, demand for payment, or
acceleration of the maturity of any obligation), shall the interest taken,
reserved, contracted for, charged or received under this Senior Note or
otherwise exceed the Highest Lawful Rate. If, from any possible construction of
any document, interest would otherwise be payable in excess of the Highest
Lawful Rate, any such construction shall be subject to the provisions of this
paragraph and such document shall be automatically reformed and the interest
payable shall be automatically reduced to the Highest Lawful Rate, without the
necessity of execution of any amendment or new document. If the Holders of this
Senior Note shall ever receive anything of value which is characterized as
interest under applicable law and which would apart from this provision be in
excess of the Highest Lawful Rate, an amount equal to the amount which would
have been excessive interest shall, without penalty, be applied to the reduction
of the principal amount owing on this Senior Note in the inverse order of its
maturity and not to the payment of interest, or refunded to the Company if and
to the extent such amount which would have been excessive exceeds such unpaid
principal. The right to accelerate the maturity of this Senior Note does not
include the right to accelerate any interest which has not otherwise accrued on
the date of such acceleration, and the Holders of this Senior Note do not intend
to charge or receive any unearned interest in the event of acceleration. All
interest paid or agreed to be paid to the Holders of this Senior Note shall, to
the extent permitted by applicable law, be amortized, prorated, allocated and
spread throughout the full stated term (including any renewal or extension) of
this Senior Note so that the amount of interest on account of this Senior Note
does not exceed the Highest Lawful Rate.

         INDENTURE SUPPLEMENT NO. 6 ("Indenture Supplement"), dated as of
January 27, 2000, between CENTEX CORPORATION, a Nevada corporation (together
with its successors and assigns as provided in the Indenture referred to below,
the "Company"), and CHASE BANK OF TEXAS, NATIONAL ASSOCIATION, a national
banking association (formerly, Texas Commerce Bank 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
March 12, 1987 (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 Subordinated Debt
Securities and to specify certain terms of each such Series of Subordinated Debt
Securities. The Board of Directors of the Company has duly authorized the
creation of a Series of Subordinated Debt Securities to be known as the
Company's Subordinated Medium-Term Notes, Series C (the "Subordinated Notes"),
and the Company and the Trustee are executing and delivering this Indenture
Supplement in order to provide for the issuance of the Subordinated 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 Fixed
Rate Note or Floating Rate Note attached hereto as Exhibits A and B,
respectively, either directly or by reference therein, shall have the meanings
assigned to them therein.

         As used in this Indenture Supplement, the following terms shall have
the following meanings:

AMORTIZED FACE AMOUNT:

         The term "Amortized Face Amount" of an Original Issue Discount Note, as
of the date that (i) the principal amount of such Subordinated Note is to be
repaid prior to its Stated Maturity, whether upon declaration of acceleration,
call for redemption, repayment at the option of the Holder or otherwise, or (ii)
any consent, notice, request, direction, waiver or suit by the Noteholders shall
be deemed to be given, made or commenced under this Indenture, shall mean the
principal amount of such Subordinated Note multiplied by its Issue Price plus
the portion of the difference between the dollar amount thus obtained and the
principal amount of such Subordinated Note that has accreted at the Yield to
maturity of such Subordinated Note (computed in accordance with generally
accepted United States bond yield computation principles) to such date, but in
no event shall the Amortized Face Amount of an Original Issue Discount Note
exceed its principal amount stated in the applicable Company Order.

AMORTIZING NOTE:

         The term "Amortizing Note" shall mean a Subordinated Note for which
payments of principal of and interest on such Subordinated Note are made in
installments over the life of such Subordinated Note, and unless otherwise
specified in the applicable Company Order, payments with respect to an
Amortizing Note shall be applied first to interest due and payable thereon and
then to the reduction of the unpaid principal amount thereof.



                                       2
<PAGE>   3



AUTHORIZED AGENT:

         The term "Authorized Agent" shall mean an agent of the Company
designated by an Officers' Certificate to give to the Trustee the information
specified in clause (a) of "Company Order" for the issuance of a Subordinated
Note.

BASIS POINT:

         The term "Basis Point" shall mean one-one hundredth of a percentage
point.

CD RATE:

         The term "CD Rate" shall mean, with respect to any CD Rate Interest
Determination Date, the rate on such date for negotiable United States dollar
certificates of deposit having the Index Maturity specified in the applicable
Pricing Supplement as published in H.15(519) (as hereinafter defined) under the
heading "CDs (secondary market)" or, if not so published by 3:00 P.M., New York
City time, on the related Calculation Date, the rate on such CD Rate Interest
Determination Date for negotiable United States dollar certificates of deposit
of the Index Maturity specified in the applicable Pricing Supplement as
published in H.15 Daily Update (as hereinafter defined), or such other
recognized electronic source used for the purpose of displaying such rate, under
the caption "CDs (secondary market)." If such rate is not yet published in
H.15(519), H.15 Daily Update or another recognized electronic source by 3:00
P.M., New York City time, on the related Calculation Date, then the CD Rate on
such CD Rate Interest Determination Date will be calculated by the Calculation
Agent and will be the arithmetic mean of the secondary market offered rates as
of 10:00 A.M., New York City time, on such CD Rate Interest Determination Date,
of three leading nonbank dealers in negotiable United States dollar certificates
of deposit in The City of New York (which may include the Agents or their
affiliates) selected by the Calculation Agent for negotiable United States
dollar certificates of deposit of major United States money center banks for
negotiable certificates of deposit with a remaining maturity closest to the
Index Maturity specified in the applicable Pricing Supplement in an amount that
is representative for a single transaction in that market at that time;
provided, however, that if the dealers so selected by the Calculation Agent are
not quoting as mentioned in this sentence, the CD Rate determined as of such CD
Rate Interest Determination Date will be the CD Rate in effect on such CD Rate
Interest Determination Date.

CD RATE INTEREST DETERMINATION DATE:

         The term "CD Rate Interest Determination Date" shall mean the Interest
Determination Date relating to a Floating Rate Note for which the interest rate
is determined with reference to the CD Rate.

CMT RATE:

         The term "CMT Rate" shall mean, with respect to any CMT Rate Interest
Determination Date, the rate displayed on the Designated CMT Telerate Page under
the caption "...Treasury Constant Maturities...Federal Reserve Board Release
H.15...Mondays Approximately 3:45 P.M.," under the column for the Designated CMT
Maturity Index for (i) if the Designated CMT Telerate Page is 7051, the rate on
such CMT Rate Interest Determination Date and (ii) if the Designated CMT
Telerate Page is 7052, the weekly or monthly average, as specified in the
Company Order, for the week or the month, as applicable, ended immediately
preceding the week or the month, as applicable, in which the related CMT Rate
Interest Determination Date falls. If such rate is no longer displayed on the
relevant page or is not so displayed by 3:00 P.M., New York City time, on the
related Calculation Date, then the CMT Rate for such CMT Rate Interest
Determination Date will be such treasury constant maturity rate for the



                                       3
<PAGE>   4



Designated CMT Maturity Index as published in H.15(519). If such rate is no
longer published or is not so published by 3:00 P.M., New York City time, on the
related Calculation Date, then the CMT Rate on such CMT Rate Interest
Determination Date will be such treasury constant maturity rate for the
Designated CMT Maturity Index (or other United States Treasury rate for the
Designated CMT Maturity Index) for the CMT Rate Interest Determination Date with
respect to such Interest Reset Date as may then be published by either the Board
of Governors of the Federal Reserve System or the United States Department of
the Treasury that the Calculation Agent determines to be comparable to the rate
formerly displayed on the Designated CMT Telerate Page and published in
H.15(519). If such information is not so provided by 3:00 P.M., New York City
time, on the related Calculation Date, then the CMT Rate on the CMT Rate
Interest Determination Date will be calculated by the Calculation Agent and will
be a yield to maturity, based on the arithmetic mean of the secondary market
offered rates as of approximately 3:30 P.M., New York City time, on such CMT
Rate Interest Determination Date reported, according to their written records,
by three leading primary United States government securities dealers in The City
of New York (which may include the Agents or their affiliates) (each, a
"Reference Dealer") selected by the Calculation Agent (from five such Reference
Dealers selected by the Calculation Agent and eliminating the highest quotation
(or, in the event of equality, one of the highest) and the lowest quotation (or,
in the event of equality, one of the lowest)), for the most recently issued
direct noncallable fixed rate obligations of the United States ("Treasury
Notes") with an original maturity of approximately the Designated CMT Maturity
Index and a remaining term to maturity of not less than such Designated CMT
Maturity Index minus one year. If the Calculation Agent is unable to obtain
three such Treasury Note quotations, the CMT Rate on such CMT Rate Interest
Determination Date will be calculated by the Calculation Agent and will be a
yield to maturity based on the arithmetic mean of the secondary market offered
rates as of approximately 3:30 P.M., New York City time, on such CMT Rate
Interest Determination Date of three Reference Dealers in The City of New York
(from five such Reference Dealers selected by the Calculation Agent and
eliminating the highest quotation (or, in the event of equality, one of the
highest) and the lowest quotation (or, in the event of equality, one of the
lowest)), for Treasury Notes with an original maturity of the number of years
that is the next highest to the Designated CMT Maturity Index and a remaining
term to maturity closest to the Designated CMT Maturity Index and in an amount
of at least $100 million. If three or four (and not five) of such Reference
Dealers are quoting as described above, then the CMT Rate will be based on the
arithmetic mean of the offered rates obtained and neither the highest nor the
lowest of such quotes will be eliminated; provided, however, that if fewer than
three Reference Dealers so selected by the Calculation Agent are quoting as
mentioned herein, the CMT Rate determined as of such CMT Rate Interest
Determination Date will be the CMT Rate in effect on such CMT Rate Interest
Determination Date. If two Treasury Notes with an original maturity as described
in the second preceding sentence have remaining terms to maturity equally close
to the Designated CMT Maturity Index, the Calculation Agent will obtain
quotations for the Treasury Note with the shorter remaining term to maturity.

CMT RATE INTEREST DETERMINATION DATE:

         The term "CMT Rate Interest Determination Date" shall mean any Interest
Determination Date relating to a Floating Rate Note for which the interest rate
is determined with reference to the CMT Rate.

CALCULATION AGENT:

         The term "Calculation Agent" for a particular Floating Rate Note shall
mean the Trustee, unless otherwise specified in the applicable Company Order.



                                       4
<PAGE>   5



CALCULATION DATE:

         The term "Calculation Date" shall, unless otherwise specified in the
applicable Company Order, mean with regard to any particular Interest
Determination Date, the earlier of (i) the tenth calendar day after such
Interest Determination Date, or, if any such day is not a Business Day, the next
day that is a Business Day, or (ii) the Business Day immediately preceding the
applicable Interest Payment Date or Maturity Date, as the case may be.

COMMERCIAL PAPER RATE:

         The term "Commercial Paper Rate" for a particular Floating Rate Note,
unless otherwise indicated in the applicable Company Order, shall mean, with
respect to any Interest Determination Date, the Money Market Yield on such date
of the rate for commercial paper having the Index Maturity specified in such
Company Order, as such rate shall be published in H.15(519) under the caption
"Commercial Paper- Nonfinancial" or, if not so published by 3:00 P.M., New York
City time, on the related Calculation Date, the rate on such Commercial Paper
Rate Interest Determination Date for commercial paper having the Index Maturity
specified in the applicable Company Order as published in H.15 Daily Update, or
such other recognized electronic source used for the purpose of displaying such
rate, under the caption "Commercial Paper-Nonfinancial." If such rate is not yet
published in H.15(519), H.15 Daily Update or another recognized electronic
source by 3:00 P.M., New York City time, on the related Calculation Date, then
the Commercial Paper Rate on such Commercial Paper Rate Interest Determination
Date will be calculated by the Calculation Agent and will be the Money Market
Yield of the arithmetic mean of the offered rates at approximately 11:00 A.M.,
New York City time, on such Commercial Paper Rate Interest Determination Date of
three leading dealers of commercial paper in The City of New York (which may
include the Agents or their affiliates) selected by the Calculation Agent for
commercial paper having the Index Maturity specified in the applicable Pricing
Supplement placed for industrial issuers whose bond rating is "Aa," or the
equivalent, from a nationally recognized statistical rating organization;
provided, however, that if the dealers so selected by the Calculation Agent are
not quoting as mentioned in this sentence, the Commercial Paper Rate determined
as of such Commercial Paper Rate Interest Determination Date will be the
Commercial Paper Rate in effect on such Commercial Paper Rate Interest
Determination Date.

COMMERCIAL PAPER RATE INTEREST DETERMINATION DATE:

         The term "Commercial Paper Rate Interest Determination Date" shall mean
any Interest Determination Date relating to a Floating Rate Note for which the
interest rate is determined with reference to the Commercial Paper Rate.

COMMERCIAL PAPER RATE NOTES:

         The term "Commercial Paper Rate Notes" shall mean Floating Rate Notes
which are specified in the applicable Company Order as bearing interest at an
interest rate calculated with reference to the Commercial Paper Rate.

COMPANY ORDER:

         The term "Company Order" shall mean:

         (a) a written order signed in the name of the Company by the Chairman
of the Board, the President or any Vice President and by the Secretary or an
Assistant Secretary of the Company, and delivered



                                       5
<PAGE>   6



to the Trustee, to authenticate a Subordinated Note and to make it available for
delivery, and specifying for such Subordinated Note the following information:

                  (1) the name of the Person in which a Subordinated Note to be
         issued and authenticated shall be registered;

                  (2) the address of such Person;

                  (3) the taxpayer identification number of such Person;

         Section 4.08. Governing Law. This Indenture Supplement and each
Subordinated Note issued hereunder shall be deemed to be a contract made under
the laws of the State of Texas, and for all purposes shall be construed in
accordance with the laws of said State.

         Section 4.09. Compliance with Law. It is the intent of the Company and
the Holders of the Subordinated Notes to conform to and contract in strict
compliance with applicable usury law from time to time in effect. All agreements
between the Holders of the Subordinated Notes and the Company are hereby limited
by the provisions of this Section 4.09 which shall override and control all such
agreements, whether now existing or hereafter arising and whether written or
oral. In no way, nor in any event or contingency (including but not limited to
prepayment, default, demand for payment, or acceleration of the maturity of any
obligation), shall the interest taken, reserved, contracted for, charged or
received under this Indenture Supplement or the Subordinated Notes or otherwise,
exceed the Highest Lawful Rate. If, from any possible construction of any
document, interest would otherwise be payable in excess of the Highest Lawful
Rate, any such construction shall be subject to the provisions of this Section
4.09 and such document shall be automatically reformed and the interest payable
shall be automatically reduced to the Highest Lawful Rate, without the necessity
of execution of any amendment or new document. If the Holders shall ever receive
anything of value which is characterized as interest under applicable law and
which would apart from this provision be in excess of the Highest Lawful Rate,
an amount equal to the amount which would have been excessive interest shall,
without penalty, be applied to the reduction of the principal amount owing on
the Subordinated Notes in the inverse order of its maturity and not to the
payment of interest, or refunded to the Company if and to the extent such amount
which would have been excessive exceeds such unpaid principal. The right to
accelerate the maturity of the Subordinated Notes does not include the right to
accelerate any interest which has not otherwise accrued on the date of such
acceleration, and the Holders do not intend to charge or receive any unearned
interest in the event of acceleration. All interest paid or agreed to be paid to
the Holders shall, to the extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full stated term (including any
renewal or extension) of the Subordinated Notes so that the amount of interest
on account of the Subordinated Notes does not exceed the Highest Lawful Rate.

principal amount to which such Original Issue Date is applicable) specified
above, or from and including the most recent Interest Payment Date specified
above to which interest has been paid or duly provided for, as the case may be.
Interest shall be paid in arrears semiannually on each Interest Payment Date in
each year commencing on (a) the first such Interest Payment Date next succeeding
the earliest Original Issue Date or Dates, or (b) if such Original Issue Date is
after a Record Date and prior to the first Interest Payment Date, on the second

first payment of interest with respect to such Original Issue Date will be made

the Person in whose name this Subordinated Note is registered at the close of
business on the Record Date for such second Interest Payment Date; and PROVIDED,
FURTHER, that interest payable on the Maturity Date or, if applicable, upon
redemption, shall be payable to the Person to whom principal shall be payable.
Except as otherwise provided in the Indenture, any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Record Date and shall be paid to the Person in whose name this
Subordinated Note is registered at the close of business on a Record Date for
the payment of such defaulted interest to be fixed by the Company, notice
whereof shall be given to Subordinated Noteholders not less than fifteen
calendar days prior to such Record Date. Payment of the principal of and any
premium and interest on this Subordinated Note shall be made on or before 10:30
A.M., New York City time or such other time as shall be agreed upon between the
Trustee and the Depositary, on the day on which such payment is due, by wire
transfer into the account specified by the Depositary; PROVIDED, HOWEVER, that
as a condition to the payment at the Maturity Date of any part of the principal
and any applicable premium of this Global Subordinated Note, the Depositary
shall surrender, or cause to be surrendered, this Global Subordinated Note to
the Trustee. The Company will pay any administrative costs imposed by banks in
connection with making payments by wire transfer, but not any tax, assessment or
governmental charge imposed on the Holder of this Subordinated Note.

         Under certain circumstances, this Global Subordinated Note is
exchangeable in whole or from time to time in part for a definitive individual
Subordinated Note or Subordinated Notes, with the same Original Issue Date or

the Trustee referred to on the reverse hereof, directly or through a duly
appointed and authorized authenticating agent, by manual signature of an
authorized signatory, this Subordinated Note shall not be entitled to any

                [REVERSE OF GLOBAL SUBORDINATED FIXED RATE NOTE]

                               CENTEX CORPORATION
               SUBORDINATED FIXED RATE MEDIUM-TERM NOTE, SERIES C

         This Global Subordinated Note is one of, and a global security which
represents Subordinated Notes which are part of, a duly authorized issue of
Subordinated Debt Securities of the Company (herein called the "Subordinated
Notes"), issued and to be issued in one or more Series under an Indenture dated
as of March 12, 1987 (herein, together with all indentures supplemental thereto,
called the "Subordinated Indenture") between the Company and Chase Bank of
Texas, National Association, as Trustee (formerly, Texas Commerce Bank National
Association) (herein called the "Trustee," which term includes any successor
Trustee under the Subordinated Indenture), to which Subordinated Indenture and
all indentures supplemental thereto (including the Indenture Supplement dated as
of January __, 2000 which authorizes the Subordinated 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 Subordinated
Noteholders, and of the terms upon which the Subordinated Notes are, and are to
be, authenticated and delivered. All terms used in this Subordinated Note which
are defined in the Subordinated Indenture or in any indenture supplemental
thereto but are not defined in this Subordinated Note shall have the meanings
assigned to them in the Subordinated Indenture or in any indenture supplemental
thereto.

         Each Subordinated Note shall be dated the date of its authentication by
the Trustee. Each Subordinated Note shall also bear an Original Issue Date or
Dates which with respect to this Global Subordinated Note (or any portion
thereof) shall mean the date or dates of the original issue of the Subordinated
Notes represented hereby as specified on the face hereof, and such Original
Issue Date or Dates shall remain the same for all Subordinated Notes
subsequently issued upon transfer, exchange or substitution of such original
Subordinated Note (or such subsequently issued Subordinated Notes) regardless of
their dates of authentication. The Subordinated Notes may bear different dates,
mature at different times, bear interest at different rates, be subject to
different redemption provisions, if any, and may otherwise vary, all as provided
in the Subordinated Indenture.

         The indebtedness evidenced by the Subordinated Notes is, to the extent
and in the manner provided in the Subordinated Indenture and Indenture
Supplement, subordinated and subject in right of payment to the prior payment in
full of all Senior Indebtedness of the Company. As provided in the Subordinated
Indenture, each holder of this Subordinated Note, by his acceptance hereof,
agrees to and shall be bound by all the provisions of the Subordinated Indenture
relating to such subordination and authorizes the Trustee to take such action in
his behalf as may be necessary or appropriate to effectuate the subordination as
provided in the Subordinated Indenture and appoints the Trustee his
attorney-in-fact for any and all such purposes.

         Interest on this Subordinated Note will be payable on the Interest
Payment Date or Interest Payment Dates as specified on the face hereof and, in
either case, at Maturity. Unless otherwise specified on the face hereof,
payments on this Subordinated Note with respect to any particular Interest
Payment Date or the Maturity Date will include interest accrued from and
including the applicable Original Issue Date, 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 Subordinated Note will be computed and paid on the basis of a
360-day year of twelve 30-day months.

         Unless otherwise specified on the face hereof or the Company Order, if
this Subordinated Note is an Amortizing Note, payments with respect to this
Subordinated Note will be applied first to interest due and payable hereon and
then to the reduction of the unpaid principal amount hereof. If this
Subordinated Note is an Amortizing Note, a table setting forth the schedule of
dates and amounts of payments of principal of and interest on this Subordinated
Note or the formula for the amortization of principal and/or interest is set
forth in an annex attached to this Subordinated Note.

         All percentages resulting from any calculation with respect to this
Subordinated Note will be rounded, if necessary, to the nearest one
hundred-thousandth of a percentage point (with five one-millionths of a
percentage point rounded upward) and all dollar or foreign or composite currency
amounts used in or resulting from any such


                                        4

<PAGE>   29

calculation with respect to this Subordinated Note will be rounded, in the case
of United States dollars, to the nearest cent or, in the case of a foreign or
composite currency, to the nearest unit (with one-half cent or unit being
rounded upward).

         If an Interest Payment Date or the Maturity Date for this Subordinated
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 Subordinated
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.

         This Subordinated Note will be redeemable at the option of the Company
prior to its Stated Maturity Date only if an Initial Redemption Date is
specified on the face hereof. If so specified, this Subordinated Note will be
subject to redemption at the option of the Company on any date on and after such
Initial Redemption Date in whole or from time to time in part in increments of
$1,000 or any other integral multiple thereof, at the redemption prices
specified in an annex attached to this Subordinated Note, plus accrued and
unpaid interest to but excluding the date of redemption, but payments due with
respect to this Subordinated Note prior to the date of redemption will be
payable to the Holder of this Subordinated Note of record at the close of
business on the relevant Record Date specified on the face hereof, all as
provided in the Subordinated Indenture. Notice of such redemption shall be given
by mailing by first-class mail a notice of such redemption not less than 20 nor
more than 60 calendar days prior to the date fixed for redemption to the Holder
of this Subordinated Note, in accordance with the provisions of the Subordinated
Indenture. In the event of redemption of this Subordinated Note in part only,
this Subordinated Note will be canceled and a new Subordinated Note or
Subordinated Notes representing the unredeemed portion hereof will be issued in
the name of the Holder hereof. This Subordinated Note is not subject to a
sinking fund unless otherwise specified in an annex attached hereto.

         If so specified on the face of this Subordinated Note, (i) this
Subordinated Note shall be subject to repayment, in whole or in part, prior to
the Stated Maturity Date at the option of the Holder on a certain date or dates
and at a certain price or prices, plus accrued and unpaid interest to but
excluding the date of payment; and/or (ii) the Interest Rate specified on the
face hereof may be reset by the Company in accordance with a formula or
otherwise on the Optional Interest Reset Date or Dates specified on the face
hereof.

         Notwithstanding anything herein to the contrary, if this Subordinated
Note is an Original Issue Discount Note as specified on the face hereof, the
amount payable in the event the principal amount hereof is declared to be due
and payable immediately by reason of an Event of Default or in the event of
redemption or repayment hereof prior to the Stated Maturity hereof, in lieu of
the principal amount due at the Stated Maturity hereof, shall be the Amortized
Face Amount of this Subordinated Note as of the date of declaration, redemption
or repayment, as the case may be. The "Amortized Face Amount" of this
Subordinated Note shall be the amount equal to the principal amount of this
Subordinated Note multiplied by the Issue Price specified on the face hereof
plus (b) the portion of the difference between the dollar amount thus obtained
and the principal amount hereof that has accreted at the Yield to Maturity
specified on the face hereof (computed in accordance with generally accepted
United States bond yield computation principles) to such date of declaration,
redemption or repayment but in no event shall the Amortized Face Amount of this
Subordinated Note exceed the principal amount stated on the face hereof.

         In case an Event of Default shall have occurred and be continuing with
respect to the Subordinated 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 Subordinated Indenture. The
Subordinated 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 Subordinated Notes then outstanding. An Event of Default with
respect to the Subordinated Debt Security of any other Series issued under the
Subordinated Indenture, including the failure to make any payment of principal
or interest with respect thereto when and as due, will not be an Event of
Default with respect to the Subordinated Notes.

         The Subordinated Indenture 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 Subordinated Notes at the time outstanding,
evidenced as in the Subordinated Indenture provided, to execute supplemental
indentures adding any


                                       5
<PAGE>   30

provisions to or changing in any manner or eliminating any of the provisions of
the Subordinated Indenture or of any supplemental indenture or modifying in any
manner the rights of the Holders of the Subordinated Notes; PROVIDED, HOWEVER,
that no such supplemental indenture shall (i) extend the fixed maturity of any
Subordinated 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
Subordinated Note so affected, or (ii) reduce the aforesaid percentage of
Subordinated Notes, the consent of the Holders of which is required for any such
supplemental indenture, without the consent of the Holders of all Subordinated
Notes then outstanding. It is also provided in the Subordinated Indenture that
the Holders of a majority in aggregate principal amount of the Subordinated
Notes at the time outstanding may on behalf of the Holders of all the
Subordinated Notes waive any past default under the Subordinated Indenture and
its consequences, except a default in the payment of the principal of or
premium, if any, or interest on any of the Subordinated Notes. Any such consent
or waiver by the Holder of this Global Subordinated Note (unless revoked as
provided in the Subordinated Indenture) shall be conclusive and binding upon
such Holder and upon all future Holders and owners of this Global Subordinated
Note and of any Subordinated Note issued in exchange or substitution herefor,
whether or not any notation of such consent or waiver is made upon this Global
Subordinated Note.

         As set forth in, and subject to, the provisions of the Subordinated
Indenture, no Holder of any Subordinated Notes will have any right to institute
any proceeding with respect to the Subordinated Indenture or for any remedy
thereunder, unless such Holder shall have previously given to the Trustee
written notice of default in respect of the Subordinated Notes and the
continuance thereof, and unless the Holders of not less than 25 percent in
aggregate principal amount of the Subordinated 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 the
enforcement of payment of the principal of and any premium or interest on this
Global Subordinated Note on or after the respective due dates expressed herein.

         THIS SUBORDINATED NOTE IS A GLOBAL SUBORDINATED NOTE REGISTERED IN THE
NAME OF THE DEPOSITARY OR A NOMINEE THEREOF AND, UNLESS AND UNTIL IT IS
EXCHANGED IN WHOLE OR IN PART FOR THE INDIVIDUAL NOTES REPRESENTED HEREBY, THIS
GLOBAL SUBORDINATED NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE
DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO
THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY
SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR
DEPOSITARY.

         If at any time the Depositary for this Global Note notifies the Company
that it is unwilling or unable to continue as Depositary for this Global Note or
if at any time the Depositary for this Global Note shall no longer be registered
as a clearing agency under the Securities Exchange Act of 1934, as amended, or
any successor statute or regulation, the Company may appoint a successor
Depositary with respect to this Global Note. If (A) a successor Depositary for
this Global Note is not appointed by the Company within 60 calendar days after
the Company receives such notice or becomes aware of such ineligibility, or (B)
any Notes are represented by this Global Note at a time when an Event of Default
with respect to the Notes shall have occurred and be continuing, then in each
case the Company's election to issue this Note in global form shall no longer be
effective with respect to this Global Subordinated Note and the Company will
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of individual Subordinated Notes in exchange for this Global
Subordinated Note, shall authenticate and make available for delivery,
individual Subordinated Notes of like tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of this Global
Subordinated Note in exchange for this Global Subordinated Note.

         If agreed by the Company and the Depositary with respect to
Subordinated Notes issued in the form of this Global Subordinated Note, the
Depositary for such Global Subordinated Note shall surrender this Global
Subordinated Note in exchange in whole or in part for individual Subordinated
Notes of like tenor and terms in definitive form on such terms as are acceptable
to the Company and such Depositary. Thereupon the Company shall execute, and the
Trustee shall authenticate and make available for delivery, without a service
charge, (1) to each Person specified by such Depositary, a new Subordinated Note
or Subordinated Notes of like tenor and terms, and of any authorized


                                       6
<PAGE>   31

denominations as requested by such Person in aggregate principal amount equal to
and in exchange for the beneficial interest of such Person in this Global
Subordinated Note, and (2) to such Depositary a new Global Subordinated Note of
like tenor and terms and in a denomination equal to the difference, if any,
between the principal amount of this Global Subordinated Note and the aggregate
principal amount of Subordinated Notes delivered to Holders thereof.

         Under certain circumstances specified in the Subordinated Indenture,
the Depositary may be required to surrender any two or more Global Subordinated
Notes which have identical terms (but which may have differing Original Issue
Dates) to the Trustee, and the Company shall execute and the Trustee shall
authenticate and deliver to, or at the direction of, the Depositary a Global
Subordinated Note in principal amount equal to the aggregate principal amount
of, and with all terms identical to, the Global Subordinated Notes surrendered
to the Trustee, and such new Global Subordinated Note shall indicate each
applicable Original Issue Date and the principal amount applicable to each such
Original Issue Date.

         No reference herein to the Subordinated Indenture and no provision of
this Global Subordinated Note or of the Subordinated 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 Global Subordinated
Note at the times, places and rates, and in the coin or currency, herein
prescribed.

         The Subordinated Indenture contains provisions for the satisfaction and
discharge of the Subordinated Indenture upon compliance by the Company with
certain conditions specified therein, which provisions apply to this
Subordinated Note.

         The Company, the Trustee, any paying agent and any Subordinated Debt
Security Registrar (as defined in the Subordinated Indenture) for the
Subordinated Notes may deem and treat the Holder hereof as the absolute owner of
this Global Subordinated Note (whether or not this Global Subordinated Note
shall be overdue and notwithstanding any notation of ownership or other writing
hereon made by anyone other than the Company or any such Subordinated 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 Subordinated 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 Global Subordinated Note, or for any claim
based hereon or otherwise in respect hereof, or based on or in respect of the
Subordinated Indenture, 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.

         It is the intent of the Company and the Holders of this Subordinated
Note to conform to and contract in strict compliance with applicable usury law
from time to time in effect. All agreements between the Holders of this
Subordinated Note and the Company are hereby limited by the provisions of this
paragraph which shall override and control all such agreements, whether now
existing or hereafter arising and whether written or oral. In no way, nor in any
event or contingency (including but not limited to prepayment, default, demand
for payment, or acceleration of the maturity of any obligation), shall the
interest taken, reserved, contracted for, charged or received under this
Subordinated Note or otherwise exceed the Highest Lawful Rate. If, from any
possible construction of any document, interest would otherwise be payable in
excess of the Highest Lawful Rate, any such construction shall be subject to the
provisions of this paragraph and such document shall be automatically reformed
and the interest payable shall be automatically reduced to the Highest Lawful
Rate, without the necessity of execution of any amendment or new document. If
the Holders of this Subordinated Note shall ever receive anything of value which
is characterized as interest under applicable law and which would apart from
this provision be in excess of the Highest Lawful Rate, an amount equal to the
amount which would have been excessive interest shall, without penalty, be
applied to the reduction of the principal amount owing on this Subordinated Note
in the inverse order of its maturity and not to the payment of interest, or
refunded to the Company if and to the extent such amount which would have been
excessive exceeds such unpaid principal. The right to accelerate the maturity of
this Subordinated Note does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and the
Holders of this


                                       7
<PAGE>   32

Subordinated Note do not intend to charge or receive any unearned interest in
the event of acceleration. All interest paid or agreed to be paid to the Holders
of this Subordinated Note shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full stated term
(including any renewal or extension) of this Subordinated Note so that the
amount of interest on account of this Subordinated Note does not exceed the
Highest Lawful Rate.

the Original Issue Date (or if this Global Subordinated Note has two or more
Original Issue Dates, interest shall, beginning on each such Original Issue
Date, begin to accrue for that part of the principal amount to which such
Original Issue Date is applicable) specified above, or from and including the
most recent Interest Payment Date specified above to which interest has been
paid or duly provided for, as the case may be. Interest shall be paid in arrears
monthly, quarterly, semiannually or annually as specified above under Interest
Payment Dates, on each Interest Payment Date in each year and at Maturity,
commencing on (a) the first such Interest Payment Date next succeeding the
earliest Original Issue Date or Dates, or (b) if such Original Issue Date is

Interest Payment Date, at a rate per annum from time to time equal to the lesser
of (i) the Highest Lawful Rate (as defined in the Indenture) or (ii) the Initial

above, and thereafter at a rate per annum determined in accordance with the
provisions in the Indenture for calculating the Interest Rate for Subordinated
Notes having the Interest Rate Basis specified above, until Maturity and the
principal hereof is paid or made available for payment. The interest so payable
and punctually paid or duly provided for on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Subordinated
Note is registered at the close of business on the Record Date specified above
next preceding such Interest Payment Date; PROVIDED, HOWEVER, that if an
Original Issue Date falls between a Record Date and the next Interest Payment
Date, the first payment of interest with respect to such Original Issue Date
will be made on the second Interest Payment Date subsequent to such Original
Issue Date to the Person in whose name this Subordinated Note is registered at
the close of business on the Record Date for such second Interest Payment Date;
and PROVIDED, FURTHER, that interest payable on the Maturity Date or, if
applicable, upon redemption, shall be payable to the Person to whom principal
shall be payable. Except as otherwise provided in the Indenture, any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Record Date and shall be paid to the Person in
whose name this Subordinated Note is registered at the close of business on a
Record Date for the payment of such defaulted interest to be fixed by the
Company, notice whereof shall be given to Subordinated Noteholders not less than
fifteen calendar days prior to such Record Date. Payment of the principal of and
any premium and interest on this Subordinated Note shall be made on or before
10:30 A.M., New York City time or such other time as shall be agreed upon
between the Trustee and the Depositary, on the day on which such payment is due,
by wire transfer into the account specified by the Depositary; PROVIDED,
HOWEVER, that as a condition to the payment at the Maturity Date of any part of
the principal and any applicable premium of this Global Subordinated Note, the
Depositary shall surrender, or cause to be surrendered, this Global Subordinated
Note to the

Trustee. The Company will pay any administrative costs imposed by banks in
connection with making payments by wire transfer, but not any tax, assessment or
governmental charge imposed on the Holder of this Subordinated Note.

         Under certain circumstances, this Global Subordinated Note is
exchangeable in whole or from time to time in part for a definitive individual
Subordinated Note or Subordinated Notes, with the same Original Issue Date or
Dates, Maturity Date, Interest Rate Basis or Bases and redemption and other
provisions as provided herein or in the Indenture.

         The Indenture and the Subordinated Notes shall be governed by, and
construed in accordance with, the laws of the State of Texas.

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS GLOBAL
SUBORDINATED NOTE SET FORTH IN FULL ON THE REVERSE HEREOF, WHICH FURTHER
PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH IN FULL
AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof, directly or through a duly
appointed and authorized authenticating agent, by manual signature of an
authorized signatory, this Subordinated Note shall not be entitled to any
benefit under the Indenture or be valid or obligatory for any purpose.

               [REVERSE OF GLOBAL SUBORDINATED FLOATING RATE NOTE]

                               CENTEX CORPORATION
              SUBORDINATED FLOATING RATE MEDIUM-TERM NOTE, SERIES C

         This Global Subordinated Note is one of, and a global security which
represents Subordinated Notes which are part of, a duly authorized issue of
Subordinated Debt Securities of the Company (herein called the "Subordinated
Notes"), issued and to be issued in one or more Series under an Indenture dated
as of March 12, 1987 (herein, together with all indentures supplemental thereto,
called the "Subordinated Indenture") between the Company and Chase Bank of
Texas, National Association, as Trustee (formerly, Texas Commerce Bank National
Association) (herein called the "Trustee," which term includes any successor
Trustee under the Subordinated Indenture), to which Subordinated Indenture and
all indentures supplemental thereto (including the Indenture Supplement dated as
of January __, 2000 which authorizes the Subordinated 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 Subordinated
Noteholders, and of the terms upon which the Subordinated Notes are, and are to
be, authenticated and delivered. All terms used in this Subordinated Note which
are defined in the Subordinated Indenture or in any indenture supplemental
thereto but are not defined in this Subordinated Note shall have the meanings
assigned to them in the Subordinated Indenture or in any indenture supplemental
thereto.

         Each Subordinated Note shall be dated the date of its authentication by
the Trustee. Each Subordinated Note shall also bear an Original Issue Date or
Dates which with respect to this Global Subordinated Note (or any portion
thereof) shall mean the date or dates of the original issue of the Subordinated
Notes represented hereby as specified on the face hereof, and such Original
Issue Date or Dates shall remain the same for all Subordinated Notes
subsequently issued upon transfer, exchange or substitution of such original
Subordinated Note (or such subsequently issued Subordinated Notes) regardless of
their dates of authentication. The Subordinated Notes may bear different dates,
mature at different times, bear interest at different rates, be subject to
different redemption provisions, if any, and may otherwise vary, all as provided
in the Subordinated Indenture.

         The indebtedness evidenced by the Subordinated Notes is, to the extent
and in the manner provided in the Subordinated Indenture, subordinated and
subject in right of payment to the prior payment in full of all Senior
Indebtedness of the Company. As provided in the Subordinated Indenture, each
holder of this Subordinated Note, by his acceptance hereof, agrees to and shall
be bound by all the provisions of the Subordinated Indenture relating to such
subordination and authorizes the Trustee to take such action in his behalf as
may be necessary or appropriate to effectuate the subordination as provided in
the Subordinated Indenture and appoints the Trustee his attorney-in-fact for any
and all such purposes.

         Interest on this Subordinated Note will be payable on the Interest
Payment Date or Interest Payment Dates as specified on the face hereof and, in
either case, at Maturity. Unless otherwise specified on the face hereof,
payments on this Subordinated Note with respect to any particular Interest
Payment Date or the Maturity Date will include interest accrued from and
including the applicable Original Issue Date, 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 Subordinated Note shall be calculated for each day during such
period by dividing the interest rate applicable to such day by 360, if the
Interest Rate Basis specified on the face hereof is the CD Rate, the Commercial
Paper Rate, the Eleventh District Cost of Funds Rate, the Federal Funds Rate,
LIBOR or the Prime Rate, or by the actual number of days in the year, if the
Interest Rate Basis specified on the face hereof is the CMT Rate or the Treasury
Rate. Unless otherwise provided in an annex attached hereto, the Trustee, acting
in the capacity of Calculation Agent, will calculate the Interest Rate on this
Subordinated Note. Upon the request of any Holder of this Subordinated Note, the
Trustee shall provide to such Holder the Interest Rate then in effect and, if
then determined, the interest rate that will become effective on the next
Interest Reset Date with respect to this Subordinated Note. Each such
determination of an Interest Rate will be final and binding in the absence of
manifest error.

         Unless otherwise specified in an annex attached hereto, if this
Subordinated Note is an Amortizing Note, payments with respect to this
Subordinated Note will be applied first to interest due and payable hereon and
then to the reduction of the unpaid principal amount hereof. If this
Subordinated Note is an Amortizing Note, a table setting


                                        5

<PAGE>   40

forth the schedule of dates and amounts of payments of principal of and interest
on this Subordinated Note or the formula for the amortization of principal
and/or interest is set forth in an annex attached to this Subordinated Note.

         All percentages resulting from any calculation with respect to this
Subordinated Note will be rounded, if necessary, to the nearest one
hundred-thousandth of a percentage point (with five one-millionths of a
percentage point rounded upward) and all dollar or foreign or composite currency
amounts used in or resulting from any such calculation with respect to this
Subordinated Note will be rounded, in the case of United States dollars, to the
nearest cent or, in the case of a foreign or composite currency, to the nearest
unit (with one-half cent or unit being rounded upward).

         If an Interest Payment Date or Maturity for this Subordinated 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 Subordinated 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. Notwithstanding the foregoing, in the case LIBOR
is the applicable Interest Rate Basis with respect to this Subordinated Note and
the next succeeding Business Day falls in the next succeeding calendar month,
payment of interest to be made on such day with respect to this Subordinated
Note will be made on the immediately preceding Business Day.

         This Subordinated Note will be redeemable at the option of the Company
prior to its Stated Maturity Date only if an Initial Redemption Date is
specified on the face hereof. If so specified, this Subordinated Note will be
subject to redemption at the option of the Company on any date on and after such
Initial Redemption Date in whole or from time to time in part in increments of
$1,000 or any other integral multiple thereof, at the redemption prices
specified in an annex attached to this Subordinated Note, plus accrued and
unpaid interest to but excluding the date of redemption, but payments due with
respect to this Subordinated Note prior to the date of redemption will be
payable to the Holder of this Subordinated Note of record at the close of
business on the relevant Record Date specified on the face hereof, all as
provided in the Subordinated Indenture. Notice of such redemption shall be given
by mailing by first-class mail a notice of such redemption not less than 20 nor
more than 60 calendar days prior to the date fixed for redemption to the Holder
of this Subordinated Note, in accordance with the provisions of the Subordinated
Indenture. In the event of redemption of this Subordinated Note in part only,
this Subordinated Note will be canceled and a new Subordinated Note or
Subordinated Notes representing the unredeemed portion hereof will be issued in
the name of the Holder hereof. This Subordinated Note is not subject to a
sinking fund unless otherwise specified in an annex attached hereto.

         If so specified on the face of this Subordinated Note, (i) this
Subordinated Note shall be subject to repayment, in whole or in part, prior to
Stated Maturity Date at the option of the Holder on a certain date or dates and
at a certain price or prices, plus accrued and unpaid interest to but excluding
the date of payment; and/or (ii) the interest rate specified on the face hereof
may be reset by the Company in accordance with a formula or otherwise on the
Optional Interest Reset Date or Dates specified on the face hereof.

         In case an Event of Default shall have occurred and be continuing with
respect to the Subordinated 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 Subordinated Indenture. The
Subordinated 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 Subordinated Notes then outstanding. An Event of Default with
respect to the Subordinated Debt Security of any other Series issued under the
Subordinated Indenture, including the failure to make any payment of principal
or interest with respect thereto when and as due, will not be an Event of
Default with respect to the Subordinated Notes.

         The Subordinated Indenture 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 Subordinated Notes at the time outstanding,
evidenced as in the Subordinated Indenture provided, to execute supplemental
indentures adding any provisions to or changing in any manner or eliminating any
of the provisions of the Subordinated Indenture or of any supplemental indenture
or modifying in any manner the rights of the Holders of the Subordinated Notes;
PROVIDED, HOWEVER, that no such supplemental indenture shall (i) extend the
fixed maturity of any Subordinated Notes, or


                                       6
<PAGE>   41

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 Subordinated Note so
affected, or (ii) reduce the aforesaid percentage of Subordinated Notes, the
consent of the Holders of which is required for any such supplemental indenture,
without the consent of the Holders of all Subordinated Notes then outstanding.
It is also provided in the Subordinated Indenture that the Holders of a majority
in aggregate principal amount of the Subordinated Notes at the time outstanding
may on behalf of the Holders of all the Subordinated Notes waive any past
default under the Subordinated Indenture and its consequences, except a default
in the payment of the principal of or premium, if any, or interest on any of the
Subordinated Notes. Any such consent or waiver by the Holder of this Global
Subordinated Note (unless revoked as provided in the Subordinated Indenture)
shall be conclusive and binding upon such Holder and upon all future Holders and
owners of this Global Subordinated Note and of any Subordinated Note issued in
exchange or substitution herefor, whether or not any notation of such consent or
waiver is made upon this Global Subordinated Note.

         As set forth in, and subject to, the provisions of the Subordinated
Indenture, no Holder of any Subordinated Notes will have any right to institute
any proceeding with respect to the Subordinated Indenture or for any remedy
thereunder, unless such Holder shall have previously given to the Trustee
written notice of default in respect of the Subordinated Notes and of the
continuance thereof, and unless the Holders of not less than 25 percent in
aggregate principal amount of the Subordinated 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 the
enforcement of payment of the principal of and any premium or interest on this
Global Subordinated Note on or after the respective due dates expressed herein.

         THIS SUBORDINATED NOTE IS A GLOBAL SUBORDINATED NOTE REGISTERED IN THE
NAME OF THE DEPOSITARY OR A NOMINEE THEREOF AND, UNLESS AND UNTIL IT IS
EXCHANGED IN WHOLE OR IN PART FOR THE INDIVIDUAL NOTES REPRESENTED HEREBY, THIS
GLOBAL SUBORDINATED NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE
DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO
THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY
SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR
DEPOSITARY.

         If at any time the Depositary for this Global Subordinated Note
notifies the Company that it is unwilling or unable to continue as Depositary
for this Global Subordinated Note or if at any time the Depositary for this
Global Subordinated Note shall no longer be registered as a clearing agency
under the Securities Exchange Act of 1934, as amended, or any successor statute
or regulation, the Company may appoint a successor Depositary with respect to
this Global Subordinated Note. If (A) a successor Depositary for this Global
Subordinated Note is not appointed by the Company within 60 calendar days after
the Company receives such notice or becomes aware of such ineligibility, or (B)
any Subordinated Notes are represented by this Global Subordinated Note at a
time when an Event of Default with respect to the Subordinated Notes shall have
occurred and be continuing, then in each case the Company's election to issue
this Subordinated Note in global form shall no longer be effective with respect
to this Global Subordinated Note and the Company will execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
individual Subordinated Notes in exchange for this Global Subordinated Note,
shall authenticate and make available for delivery, individual Subordinated
Notes of like tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of this Global Subordinated Note in
exchange for this Global Subordinated Note.

         If agreed by the Company and the Depositary with respect to
Subordinated Notes issued in the form of this Global Subordinated Note, the
Depositary for such Global Subordinated Note shall surrender this Global
Subordinated Note in exchange in whole or in part for individual Subordinated
Notes of like tenor and terms in definitive form on such terms as are acceptable
to the Company and such Depositary. Thereupon the Company shall execute, and the
Trustee shall authenticate and make available for delivery, without a service
charge, (1) to each Person specified by such Depositary, a new Subordinated Note
or Subordinated Notes of like tenor and terms, and of any authorized
denominations as requested by such Person in aggregate principal amount equal to
and in exchange for the beneficial interest of such Person in this Global
Subordinated Note, and (2) to such Depositary a new Global Subordinated Note


                                       7
<PAGE>   42

of like tenor and terms and in a denomination equal to the difference, if any,
between the principal amount of this Global Subordinated Note and the aggregate
principal amount of Subordinated Notes delivered to Holders thereof.

         Under certain circumstances specified in the Subordinated Indenture,
the Depositary may be required to surrender any two or more Global Subordinated
Notes which have identical terms (but which may have differing Original Issue
Dates) to the Trustee, and the Company shall execute and the Trustee shall
authenticate and deliver to, or at the direction of, the Depositary a Global
Subordinated Note in principal amount equal to the aggregate principal amount
of, and with all terms identical to, the Global Subordinated Notes surrendered
to the Trustee, and such new Global Subordinated Note shall indicate each
applicable Original Issue Date and the principal amount applicable to each such
Original Issue Date.

         No reference herein to the Subordinated Indenture and no provision of
this Global Subordinated Note or of the Subordinated 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 Global Subordinated
Note at the times, places and rates, and in the coin or currency, herein
prescribed.

         The Subordinated Indenture contains provisions for the satisfaction and
discharge of the Subordinated Indenture upon compliance by the Company with
certain conditions specified therein, which provisions apply to this
Subordinated Note.

         The Company, the Trustee, any paying agent and any Subordinated Debt
Security Registrar (as defined in the Subordinated Indenture) for the
Subordinated Notes may deem and treat the Holder hereof as the absolute owner of
this Global Subordinated Note (whether or not this Global Subordinated Note
shall be overdue and notwithstanding any notation of ownership or other writing
hereon made by anyone other than the Company or any such Subordinated 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 Subordinated 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 Global Subordinated Note, or for any claim
based hereon or otherwise in respect hereof, or based on or in respect of the
Subordinated Indenture, 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.

         It is the intent of the Company and the Holders of this Subordinated
Note to conform to and contract in strict compliance with applicable usury law
from time to time in effect. All agreements between the Holders of this
Subordinated Note and the Company are hereby limited by the provisions of this
paragraph which shall override and control all such agreements, whether now
existing or hereafter arising and whether written or oral. In no way, nor in any
event or contingency (including but not limited to prepayment, default, demand
for payment, or acceleration of the maturity of any obligation), shall the
interest taken, reserved, contracted for, charged or received under this
Subordinated Note or otherwise exceed the Highest Lawful Rate. If, from any
possible construction of any document, interest would otherwise be payable in
excess of the Highest Lawful Rate, any such construction shall be subject to the
provisions of this paragraph and such document shall be automatically reformed
and the interest payable shall be automatically reduced to the Highest Lawful
Rate, without the necessity of execution of any amendment or new document. If
the Holders of this Subordinated Note shall ever receive anything of value which
is characterized as interest under applicable law and which would apart from
this provision be in excess of the Highest Lawful Rate, an amount equal to the
amount which would have been excessive interest shall, without penalty, be
applied to the reduction of the principal amount owing on this Subordinated Note
in the inverse order of its maturity and not to the payment of interest, or
refunded to the Company if and to the extent such amount which would have been
excessive exceeds such unpaid principal. The right to accelerate the maturity of
this Subordinated Note does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and the
Holders of this Subordinated Note do not intend to charge or receive any
unearned interest in the event of acceleration. All interest paid or agreed to
be paid to the Holders of this Subordinated Note shall, to the extent permitted
by applicable law, be


                                        8

<PAGE>   43

amortized, prorated, allocated and spread throughout the full stated term
(including any renewal or extension) of this Subordinated Note so that the
amount of interest on account of this Subordinated Note does not exceed the
Highest Lawful Rate.
