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 B (the "Senior Notes") and its Subordinated Medium-Term Notes, Series B
(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 second
Supplemental Indenture thereto dated as of August 1, 1999, and the Subordinated
Notes will be issued under a Subordinated Indenture (the "Subordinated
Indenture") dated as of March 12, 1987, as supplemented by a fifth Supplemental
Indenture thereto dated as of August 1, 1999, 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 $250,000,000 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
principal or through an Agent as agent), as


                                       2

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 of Notes or similar changes, 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. 333-72893), as amended by Amendments Nos. 1, 2, 3 and 4, in respect of the
Notes in the form heretofore delivered or to be delivered to each Agent (the
various parts of such registration statement, including Amendments Nos. 1, 2, 3
and 4, 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 part 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 the Notes and the prospectus supplement 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 reference therein as of the date of such filing or
transmission);

         (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;

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;

         (d) Neither the Company nor any of its subsidiaries has sustained since

         (e) The Company and its subsidiaries have indefeasible title in fee
simple to all real property and indefeasible title to all personal property

         (h) The Notes have been duly authorized, and, when executed,

authorized, executed and delivered by the Company and, assuming the Remarketing

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).

         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


                                       8
<PAGE>   9


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
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


                                       9
<PAGE>   10


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.

         (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.


                                       10
<PAGE>   11


         (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.

         (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


                                       11
<PAGE>   12


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 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 such information to such Agent, confirmed in
writing, and shall cause the Registration Statement and the Prospectus to be
amended, 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.


                                       12

         (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, offer or sell, or enter into any
agreement to sell, any debt securities of the Company (other than the Notes that

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 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.

                           (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,
         the National Association of Securities Dealers, Inc., the Chicago Board
         Options Exchange, the Chicago Mercantile Exchange or the Chicago Board
         of Trade, (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


                                       15
<PAGE>   16


         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 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 such 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 Thompson & Knight
         L.L.P, special counsel for the Company (as to (vii), (viii), (xi),
         (xii) and (xiv) 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;

                           (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


                                       16
<PAGE>   17


                  its jurisdiction of incorporation or organization, as the case
                  may be; 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, if
                  determined adversely to the Company or any of its
                  subsidiaries, would individually or in the aggregate 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 and each constitutes a
                  valid and legally binding obligation of the Company,
                  enforceable against the Company in accordance with their
                  respective terms, subject, as to enforcement, to bankruptcy,
                  insolvency, reorganization and other laws of general
                  applicability relating to or affecting creditors' rights and
                  to general equity principles that may limit the availability
                  of certain remedies (including specific performance), and
                  except to the extent that rights of indemnification thereunder
                  may be limited by applicable law or equity principles;

                           (vii) The Notes, in the form(s) certified by the
                  Company as of the date hereof, have been duly authorized for
                  issuance, offer and sale pursuant to this Agreement 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 Company entitled to the
                  benefits provided by the applicable Indenture and enforceable
                  against the Company in accordance with their respective terms,
                  subject, as to enforcement, to bankruptcy, insolvency,
                  reorganization and other laws of general applicability
                  relating to or affecting creditors' rights and to general
                  equity principles that may limit the availability of certain
                  remedies (including specific performance); and the Notes and
                  the


                                       17
<PAGE>   18


                  Indentures conform in all material respects to the
                  descriptions thereof in the Prospectus;

                           (viii) Each of the Indentures has been duly
                  authorized, executed and delivered by the Company and
                  constitutes a valid and legally binding instrument enforceable
                  against the Company in accordance with its terms, subject, as
                  to enforcement, to bankruptcy, insolvency, reorganization and
                  other laws of general applicability relating to or affecting
                  creditors' rights and to general equity principles that may
                  limit the availability of certain remedies (including specific
                  performance); and each of the Indentures has been duly
                  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 conflict with 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, 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 the best of such counsel's knowledge, no
                  consent, approval, authorization, order, registration or
                  qualification of or with any court or governmental agency or
                  body 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 each Agent;

                           (xii) The Registration Statement is effective under
                  the Securities Act, and, to the best of such counsel's
                  knowledge, no proceedings for a stop order 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) such counsel (1) believes that (other than the
                  financial statements and related schedules therein as to which
                  such counsel need express no belief and except for that part
                  of the Registration Statement that constitutes the Form T-l
                  heretofore referred to) each part of the Registration
                  Statement, as amended, if applicable, when 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) did
                  not and, as of the date such opinion is delivered, does not
                  contain any untrue statement of a material fact or did not and
                  does not omit to state a material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading, (2) is of the opinion that the Registration
                  Statement and the Prospectus, as amended or supplemented, if
                  applicable (other than the financial statements and related
                  schedules therein, as to which such counsel need express no
                  opinion), comply as to form in all material respects with the
                  Securities Act and the rules and regulations of the SEC
                  thereunder and (3) believes that (other than the financial
                  statements and related schedules therein as to which such
                  counsel need express no belief) the Prospectus, as of the date
                  such letter is delivered (or, if such letter is being
                  delivered in connection with the purchase of Notes from the
                  Company by an Agent as principal pursuant to Section 2(a)
                  hereof, at the date of any agreement by an Agent to purchase
                  such Notes as principal and at the Settlement Date with
                  respect thereto, as the case may be) (did not and) does not
                  include any untrue statement of a material fact or (did not
                  and) does not omit to state a material fact necessary in


                                       19
<PAGE>   20


                  order to make the statements therein, in the light of the
                  circumstances under which they were made, not misleading.

                  (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, 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 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 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 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


                                       20
<PAGE>   21


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 accorded by any "nationally recognized statistical rating
organization," as that term is defined by the SEC for purposes of Rule 436(g)(2)
under the Securities Act to any of the Company's debt securities 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 in securities generally on or by, as the case may
be, the New York Stock Exchange; (ii) a general moratorium on commercial banking
activities in New York or Texas declared by either federal or New York State or
Texas authorities; or (iii) the engagement by the United States in hostilities
that have resulted in the declaration, on or after the date of such Terms
Agreement, of a national emergency or war if the effect of any such event
specified in this clause (iii), in your reasonable judgment, makes it
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 of Notes 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


                                       21
<PAGE>   22


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 of the Notes 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 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
forthwith to each Agent and to its counsel a written opinion of Thompson &
Knight, independent 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 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


                                       23
<PAGE>   24


party from any liability which it may have otherwise than on account of this
indemnity agreement. An indemnifying party may participate at its own expense
and, to the extent that it wishes, jointly with any other indemnifying party,
similarly notified, in the defense of such action with counsel chosen by it (who
shall not, except with the consent of the indemnified party, be counsel to such
indemnified party). 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 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


                                       24
<PAGE>   25


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 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, the National
Association of Securities Dealers, Inc., the Chicago Board Options Exchange, the
Chicago Mercantile Exchange or the Chicago Board of Trade, (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 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 reasonable
judgment, impracticable to market the Notes or to enforce contracts for the sale
of the Notes, 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


                                       25
<PAGE>   26


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

                  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

         INDENTURE SUPPLEMENT NO. 2 ("Indenture Supplement"), dated as of August
1, 1999, 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 B (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 "CD (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 "CD (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 Interest
Determination Date relating to a Floating Rate Note for which the interest rate
is determined with reference to the CMT Rate, 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


                                       -3-

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.

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.


                                       -3-


<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


                                       -4-

                                   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:

                  (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


                                      -21-

<PAGE>   23


         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

         INDENTURE SUPPLEMENT NO. 5 ("Indenture Supplement"), dated as of August
1, 1999, 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 B (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.


                                      -1-

<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 "CD (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 "CD (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 Interest
Determination Date relating to a Floating Rate Note for which the interest rate
is determined with reference to the CMT Rate, 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


                                      -2-

<PAGE>   4

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.

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.


                                      -3-

<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


                                      -4-
