receive and disburse all Subscription Proceeds and earnings, if any, thereon in
accordance with the terms of this Agreement. The Escrow Agent hereby represents
to the Company and to each Selected Placement Agent that it is a "bank" as such
term is defined by Section 3(a)(6) of the Securities Exchange Act of 1934, as
amended ("Exchange Act").

     2.   Deposit Procedure.

     (a) The Escrow Agent shall establish an appropriate segregated account
("Escrow Account") designated as the " International Monetary Systems, Ltd.
Escrow Account," or with such other appropriate designation as shall be assigned
by the Escrow Agent and communicated to the Company and the Managing Placement
Agent. The Escrow Agent shall cause all Subscription Proceeds transmitted to it
by the Selected Placement Agents to be held in the Escrow Account. All checks
received by the Escrow Agent are to be held uncashed until required to be
submitted for collection pursuant to paragraph 2(b) of this Agreement.

     (b) All Subscription Proceeds received by the Selected Placement Agents
shall be delivered to the Escrow Agent, at 101 Falls Road, Grafton, Wisconsin
53024, by 12:00, noon, on the business day following receipt thereof by a
Selected Placement Agent, together with a schedule of such payments and the
subscriptions represented thereby. Provided that the Escrow Agent shall have
received with respect to each subscription for Common Stock (i) Facsimile Notice
(as defined herein) from the Company that a subscription has been received by
the Company and (ii) Subscription Proceeds in the amount required to pay in full
for such subscription, delivered by a Selected Placement Agent as aforesaid, the
Escrow Agent shall immediately commence the collection process (as applicable)
with respect to such Subscription Proceeds. Any payment item which is returned
to the Escrow Agent on its initial presentation for payment need not again be
presented for collection. The Facsimile Notice provided for in this paragraph
shall be given by the Company not more than five (5) days following receipt by
the Escrow Agent of such Subscription Proceeds and not less than two (2)
business days prior to any disbursement of Subscription Proceeds by the Escrow
Agent pursuant to this Agreement.

     (c) If a subscription is not accepted by the Company, the Company shall,
within five (5) days following its receipt from a Selected Placement Agent of
such subscription, provide the Escrow Agent with Facsimile Notice (as defined
herein) of the name of the rejected subscriber, the address of the rejected
subscriber, and the amount of Subscription Proceeds received from such rejected
subscriber and delivered to the Escrow Agent by a Selected Placement Agent, as
reported to the Company pursuant to the Managing Placement Agent Agreement.

     (d) If the Escrow Agent is holding collected funds with respect to a
rejected subscription, the Escrow Agent shall promptly remit the full amount of
Subscription Proceeds received by a Selected Placement Agent and delivered to
the Escrow Agent, with interest thereon at its passbook rate for the period held
in escrow, to the rejected subscriber at the address provided by the Company. If
the Escrow Agent has presented the Subscription Proceeds of a rejected
subscriber for collection but has not yet collected funds, the Escrow Agent
shall, promptly upon collection of such funds, remit the full amount of
Subscription Proceeds received by a Selected Placement Agent and delivered to
the Escrow Agent, with interest thereon at its passbook rate for the period held
in escrow, to the rejected subscriber at the address provided by the Company. If
the Escrow Agent has not yet presented the Subscription Proceeds of a rejected
subscriber for collection, the Escrow Agent shall promptly return in full the
Subscription Proceeds received by a Selected Placement Agent and delivered to
the Escrow Agent in the form so received and delivered, with interest thereon at
its passbook rate for the period held in escrow, to the rejected subscriber at
the address provided by the Company.

     3. Investment of Escrow Funds. The Escrow Agent shall invest all funds held
in the Escrow Account (including earnings, if any, thereon) in United States
government securities or securities guaranteed by the United States,
certificates of deposit of banks located in the United States or any other
investment, provided, in each case, that such investment is permitted by Rule
15c2-4, promulgated by the Securities and Exchange Commission under the Exchange
Act ("Rule 15c2-4"), and NASD Notice to Members 84-7. Such investments shall be
made in a manner consistent with the requirement that the Subscription Proceeds
be available for delivery by the Escrow Agent at the times described herein. The
parties hereto recognize that there may be a forfeiture of interest in the event
of early withdrawal from an interest-bearing account of investment.

     4.   Initial Closing.

     (a) If the Escrow Agent shall (i) be holding in escrow collected funds
representing Subscription Proceeds in an amount equal to the full purchase price
of 50,000 shares of Common Stock and (ii) have received from the Company and the
Managing Placement Agent, on or before the Termination Date and the Initial
Closing Date,

                                        2

respectively, the Facsimile Notice (as defined herein) and related Confirmation
(as defined herein) described in paragraph 4(b) hereof, then the Escrow Agent
shall disburse the collected funds then held in the Escrow Account (less fees of
the Escrow Agent as provided herein) to the Company and to the Managing
Placement Agent, as provided herein and subject to the provisions hereof, at the
Initial Closing. As used in this Agreement, the terms "Initial Closing" and
"Initial Closing Date" shall have the meanings ascribed to such terms in Section
4(g) of the Managing Placement Agent Agreement; the Initial Closing shall be
scheduled as provided therein.

     (b) On or before the Termination Date, the Escrow Agent shall have received
Facsimile Notice (as defined herein) from the Company and the Managing Placement
Agent that all conditions precedent to the disbursement of Subscription Proceeds
on the Initial Closing Date (including without limitation all of the conditions
set forth in Section 9 of the Managing Placement Agent Agreement) have been
fully satisfied as required under the Prospectus, the Managing Placement Agent
Agreement, Rule 15c2-4 and/or NASD Notices to Members 84-64 and 84-7,
specifically certifying that subscriptions for not less than 50,000 shares of
Common Stock have been received and accepted by the Company on or before the
Termination Date; Confirmation (as defined herein) of such Facsimile Notice
shall be delivered to the Escrow Agent on or before the Initial Closing Date,
dated as of the Initial Closing Date.

     (c) Provided that the Escrow Agent shall have (i) received and be holding
in escrow collected Subscription Proceeds as required under paragraph 4(a)
hereof, (ii) received the Facsimile Notice (as defined herein) required under
paragraph 4(b) hereof on or before the Termination Date and (ii) received
Confirmation (as defined herein) of the Facsimile Notice required under
paragraph 4(b) hereof on or before the Initial Closing Date, the Escrow Agent
shall, on the Initial Closing Date, disburse the collected funds then held in
the Escrow Account as follows: First, to the Escrow Agent in the amount of any
fees then due and payable to such Agent (which shall not exceed on the Initial
Closing Date the aggregate earnings, if any, on funds held in the Escrow
Account, determined as of the business day immediately preceding such Closing
Date); Second, to the Managing Placement Agent in an amount equal to the
aggregate selling commissions and expense allowances then due and payable to the
Selected Placement Agents pursuant to the Managing Placement Agent Agreement;
and Third, to the Company in the amount of any balance then remaining in the
Escrow Account.

     (d) If any of the conditions described in paragraphs 4(a) and 4(b) hereof
shall not have been fully satisfied at the close of business on the date
(Termination Date or Initial Closing Date) specified herein for such compliance,
the Escrow Agent shall promptly return all Subscription Proceeds directly to
subscribers, with interest thereon at its passbook rate for the period held in
escrow, and the escrow provided for herein shall thereupon terminate.

     5.   Additional Closings.

     (a) Subsequent to the Initial Closing Date, the collected funds then held
in the Escrow Account shall be disbursed by the Escrow Agent from time to time,
as provided in Section 4(g) of the Managing Placement Agent Agreement, at one or
more Additional Closings. As used herein, the terms "Additional Closing" and "
Additional Closing Date" shall have the meanings ascribed to such terms in
Section 4(g) of the Managing Placement Agent Agreement; Additional Closings
shall be scheduled as provided in such Agreement; provided, however, that no
Additional Closing shall occur less than seven (7) days nor more than thirty
(30) days following the immediately preceding Closing.

     (b) Prior to the disbursement of collected funds held in the Escrow Account
at any Additional Closing, the Escrow Agent shall have received Facsimile Notice
(as defined herein) from the Company and the Managing Placement Agent that all
conditions precedent to such disbursement by the Escrow Agent (including without
limitation all of the conditions set forth in Section 9 of the Managing
Placement Agent Agreement) have been fully satisfied as required under the
Prospectus, the Managing Placement Agent Agreement, Rule 15c2-4 and NASD Notices
to Members 84-64 and 84-7. The Facsimile Notice from the Company and the
Managing Placement Agent provided for in this paragraph 5(b) must be received by
the Escrow Agent not less than two (2) business days prior to such Additional
Closing Date; Confirmation (as defined herein) of such Facsimile Notice shall be
delivered to the Escrow Agent by the Company and the Managing Placement Agent on
or before such Additional Closing Date, dated as of such Additional Closing
Date.

all transactions hereunder. Promptly upon the termination of escrow, or as may
reasonably be requested by the Company or the Managing Placement Agent prior
thereto, the Escrow Agent shall provide the Company and the Managing Placement
Agent with a complete copy of such records, certified by the Escrow Agent to be
a complete and accurate account of all such transactions. The authorized
representatives of the Company and the Managing Placement Agent shall also have
access to such books and records at all reasonable times during normal business
hours upon reasonable notice to the Escrow Agent.

willful misconduct and, except with respect to claims based upon such negligence
or willful misconduct that are successfully asserted against the Escrow Agent.

successor Escrow Agent) from and against any and all losses, liabilities,
claims, actions, damages and expenses, including reasonable attorneys' fees and
disbursements, arising out of and in connection with this Agreement.

     (c) The Escrow Agent shall be entitled to rely upon any order, judgment,
certification, demand, notice, instrument or other writing delivered to it

statement or execute any documents in connection with the provisions of this
Agreement has been duly authorized to do so.

     (d) In the event that the Escrow Agent (i) shall be uncertain as to its
duties arising under this Agreement or (ii) shall receive instructions from the
Company or the Managing Placement Agent as to the funds held in the Escrow
Account which, in its opinion, are inconsistent with each other or are in any
conflict with any of the provisions of this Agreement, the Escrow Agent shall be

with any other amounts which shall accrue to or be deposited in the Escrow
Account, pending the settlement of any such controversy by final adjudication of

competent jurisdiction, whereupon the Escrow Agent shall be discharged of and

a successor (including a court of competent jurisdiction) or (ii) thirty (30)

of a written designation by the Company of a successor escrow agent or a final
order of a court of competent jurisdiction.

     (g) This Agreement shall be binding upon and inure solely to the benefit of
the parties hereto and their respective successors and assigns, and shall not be

assign any of its rights or obligations under this Agreement without the prior
written consent of the other parties hereto.

     (h) This Agreement may only be modified by a written instrument signed by
the parties hereto, and no waiver hereunder shall be effective unless in writing
signed by the party to be charged.

                                   Schedule A

                  This Schedule A to the Escrow Agreement, dated as of
         , 2000, by and among Grafton State Bank ("Escrow Agent"),
International Monetary Systems, Ltd. ("Company") and J.E. Liss & Company, Inc.
("Managing Placement Agent"), sets forth the compensation arrangements referred
to in paragraph 7 of such Agreement, as follows:

                  For services performed by it pursuant to the Escrow Agreement,
the Escrow Agent shall be entitled to receive from the Company fees in the
amounts of $2,500, payable upon the execution hereof, plus $250 per Closing and
$10 per subscriber (whether accepted or rejected); provided, however, that the
Escrow Agent shall receive, in the aggregate, not less than $3,000 in
consideration of its services rendered pursuant to the terms of the Escrow
Agreement. Except for the initial payment due upon the execution of this
Agreement, such fees shall be (a) due and payable on the Initial Closing Date
and each Additional Closing Date until paid in full and (b) payable, through the
final Closing, only from and to the extent of available Escrow Income; provided
that, if payments made from available Escrow Income, made at the Initial Closing
and one or more Additional Closings are not, in the aggregate, sufficient to pay
such fees in full, the Company shall pay on demand any such fees which remain
unpaid following the final Closing. "Escrow Income" is the amount of interest
and/or dividends, if any, which shall have been (x) paid on or in respect of the
Escrow Account (representing earnings on funds held therein) and (y) deposited
in such Account as collected funds on or prior to the business day immediately
preceding such Initial Closing Date or Additional Closing Date, as the case may
be. If and to the extent that Escrow Income exceeds the aggregate fees payable
to the Escrow Agent hereunder, such excess shall be paid to the Company at the
Initial Closing or Additional Closing(s), as the case may be. The foregoing
notwithstanding, if the Offering is terminated prior to the Initial Closing,
pursuant to the provisions of Section 12 of the Managing Placement Agent
Agreement or otherwise, the Escrow Agent shall be entitled to receive fees in
the aggregate amount of $3,500, and no more, payable by the Company on demand.
All terms used herein shall have the same meanings ascribed to them in the
Escrow Agreement of which this Schedule is a part.<PAGE>   1

                  INDENTURE SUPPLEMENT NO. 4 ("Indenture Supplement"), dated as
of June 19, 2000, between CENTEX CORPORATION, a Nevada corporation (together
with its successors and assigns as provided in the Indenture referred to below,
the "Company"), and CHASE BANK OF TEXAS, NATIONAL ASSOCIATION, a national
banking association (together with its successors in trust thereunder as
provided in the Indenture referred to below, the "Trustee"), as trustee under
an Indenture dated as of October 1, 1998 (the "Indenture").

                             PRELIMINARY STATEMENT

                  Section 2.02 of the Indenture provides, among other things,
that the Company may, when authorized by its Board of Directors, and the
Trustee may at any time and from time to time, enter into a series supplement
to the Indenture for the purpose of authorizing one or more Series of Senior
Debt Securities and to specify certain terms of each such Series of Senior Debt
Securities. The Board of Directors of the Company has duly authorized the
creation of a Series of Senior Debt Securities to be known as the Company's
9.750% Notes due 2005 (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

                                  ARTICLE TWO

                        Terms and Issuance of the Notes

                  Section 2.01. Issuance and Designation. A Series of Senior
Debt Securities which shall be designated as the Company's "9.750% Notes due
2005" shall be executed, authenticated and delivered in accordance with the
provisions of, and shall in all respects be subject to, the terms, conditions
and covenants of, the Indenture and this Indenture Supplement (including the
form of Note set forth in Exhibit A). The aggregate principal amount of the
Notes which may be authenticated and delivered under this Indenture Supplement
shall not, except as permitted by the provisions of the Indenture, exceed
$200,000,000, provided that the Company may, without the consent of the Holders
of the Notes, reopen this Series and issue additional Notes under the Indenture
and this Indenture Supplement in addition to the $200,000,000 of Notes
authorized as of the date hereof.

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

                  Section 2.03. Place and Method of Payment. The place of
payment in respect of the Notes will be at the principal office or agency of
the Company in Dallas, Texas or at the office or place of business of the
Trustee or its successor in trust under the Indenture, which, at the date
hereof, is located at Chase Global Trust, 600 Travis Street, Suite 1150,
Houston, Texas 77002. Payments in respect of principal or premium, if any, on
Notes will be made only against surrender of such Notes at such office.
Payments of interest on each Interest Payment Date with respect to each Note
will be made to the Person in whose name such Note is registered at the close
of business on the Regular Record Date immediately preceding such Interest
Payment Date by U.S. dollar check drawn on a bank in the City of New York or,
for Holders of at least $1,000,000 of Notes, by wire transfer to a dollar
account maintained by the payee with a bank in the United States; provided that
a written request from such Holder to such effect designating such account is
received by the Trustee or the Paying Agent no later than 30 calendar days
preceding such Interest Payment Date. Unless such designation is revoked, any
such designation

                                       3
<PAGE>   6

made by such Holder with respect to such Note payable to such Holder will
remain in effect with respect to any further interest payments with respect to
such Note payable to such Holder. The Company will pay any administrative costs
imposed by banks in connection with making interest payments by wire transfer.

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

                                 ARTICLE THREE

                              Additional Covenants

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

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

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

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

                                       4
<PAGE>   7

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

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

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

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

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

                           (viii) any Lien imposed by law.

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

                  Section 3.02. Limitation on Sale and Lease-Back Transactions.
The Company will not, nor will it permit any of its subsidiaries to, enter into
any arrangement with any Person (other than the Company) providing for the
leasing by the Company or a subsidiary of any of its

                                       5
<PAGE>   8

properties or assets (except for temporary leases for a term of not more than
three (3) years and except for sales and leases of model homes), which property
or asset has been or is to be sold or transferred by the Company or such
subsidiary to such Person (herein referred to as a "Sale and Lease-Back
Transaction"), unless (a) the net proceeds to the Company or such subsidiary
from such sale or transfer equal or exceed the fair value (as determined by the
Board of Directors, the Chairman of the Board, the Vice Chairman, the President
or the principal financial officer of the Company) of the property or asset so
leased, (b) the Company or such subsidiary would be entitled to incur
Indebtedness secured by a Lien on the property or asset to be leased pursuant
to Section 3.01, (c) the Company shall, and in any such case the Company
covenants that it will, apply an amount equal to the fair value (as determined
by the Board of Directors, the Chairman of the Board, the Vice Chairman, the
President or the principal financial officer of the Company) of the property or
asset so leased to the retirement (other than any mandatory retirement), within
180 days of the effective date of any such Sale and Lease-Back Transaction, of
Funded Indebtedness of the Company, (d) such Sale and Lease-Back Transaction
relates to a sale which occurred within 180 days from the date of acquisition
of such property or asset by the Company or a subsidiary or the date of the
completion of construction or commencement of full operations on such property,
whichever is later, or (e) such transaction was consummated prior to the date
of this Indenture Supplement.

                                  ARTICLE FOUR

                                   Defeasance

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

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

                  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

                                       6
<PAGE>   9

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

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

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

                  (2) Notwithstanding the foregoing paragraph, the Company's
         obligations in Sections 2.06, 2.08, 5.01, 5.02, 5.05, 6.01, 8.06,
         8.10, 13.04 and 13.05 of the Indenture

                           [FORM OF REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Senior Debt
Securities of the Company designated as its ___% Notes due 20__ (herein called
the "Notes"), issued and to be issued in one or more Series under an Indenture
dated as of October 1, 1998 (herein called the "Indenture") between the Company
and Chase Bank of Texas, National Association, as Trustee (herein called the
"Trustee," which term includes any successor Trustee under the Indenture), to
which Indenture and all indentures supplemental thereto (including the
Indenture Supplement dated as of _______ ___, 2000 which authorizes the Notes)
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Notes, and of the terms upon which the Notes are, and are to be,
authenticated and delivered.

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

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

                  Interest on this Note will be payable on the Interest Payment
Date or Interest Payment Dates as specified on the face hereof and, in either
case, on the Maturity Date. Unless otherwise specified on the face hereof,
payments on this Note with respect to any particular Interest Payment Date or
the Maturity Date will include interest accrued from and including
______________, 2000, or from and including the most recent Interest Payment
Date to which interest has been paid or duly provided for, to but excluding the
particular Interest Payment Date or the Maturity Date. Interest on this Note
will be computed and paid on the basis of a 360-day year of twelve 30-day
months.

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

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

                  "Comparable Treasury Issue" means the United States Treasury
security selected by the Independent Investment Banker (as hereinafter defined)
as having a maturity comparable to the remaining term of the Notes to be
redeemed that would be utilized, at the time of selection

                                       4
<PAGE>   17

and in accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining term of the
Notes.

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

                  "Independent Investment Banker" means Chase Securities Inc.

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

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

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

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

                  Notice of any redemption by the Company will be mailed at
least 30 days but not more than 60 days before any Redemption Date to each
Holder of Notes to be redeemed. If less than all the Notes are to be redeemed
at the option of the Company, the Trustee shall select the Notes to be redeemed
in whole or in part by random lot.

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

                  In case an Event of Default shall have occurred and be
continuing with respect to the Notes, the principal hereof may be declared, and
upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture. The Indenture
provides that in certain events such declaration and its consequences may be
waived by the Holders of a majority in aggregate principal amount of the Notes
then

                                       5
<PAGE>   18

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

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

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

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

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

                                       6
<PAGE>   19

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

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

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

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