                  INDENTURE SUPPLEMENT NO. 17 ("Indenture Supplement"), dated as
of June 6, 2005, between CENTEX CORPORATION, a Nevada corporation (together with
its successors and assigns as provided in the Indenture referred to below, the
"Company"), and JPMORGAN CHASE BANK, N.A., a national banking association
(formerly, The Chase Manhattan Bank, successor to Chase Bank of Texas, National
Association) (together with its successors in trust thereunder as provided in
the Indenture referred to below, the "Trustee"), as trustee under an Indenture
dated as of October 1, 1998 (the "Indenture").

                              PRELIMINARY STATEMENT

                  Section 2.02 of the Indenture provides, among other things,
that the Company may, when authorized by its Board of Directors, and the Trustee
may at any time and from time to time, enter into a series supplement to the
Indenture for the purpose of authorizing one or more Series of Senior Debt
Securities and to specify certain terms of each such Series of Senior Debt
Securities. The Board of Directors of the Company has duly authorized the
creation of a Series of Senior Debt Securities to be known as the Company's
5.25% Senior Notes due 2015 (the "Notes"), and the Company and the Trustee are
executing and delivering this Indenture Supplement in order to provide for the
issuance of the Notes.

                                   ARTICLE ONE

                                   Definitions

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

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

sheet of the Company and its subsidiaries, less applicable reserves and other
properly deductible items and after deducting therefrom (a) all current
liabilities and (b) all goodwill, trade names, trademarks, patents, unamortized
debt discount and expense, and other like intangibles, all in accordance with

an installment of interest on the Notes.

MATURITY DATE:

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

herein provided, whether at Stated Maturity, upon declaration of acceleration,
call for redemption or otherwise.

NOTEHOLDER; HOLDER:

Security Register kept for that purpose in accordance with the terms hereof.

<PAGE>
SPECIAL RECORD DATE:

                  The term "Special Record Date" for the payment of any

by or on behalf of the Company to the Holder of such Note not less than fifteen
calendar days prior to such Special Record Date.

STATED MATURITY:

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

                                   ARTICLE TWO

                         Terms and Issuance of the Notes

                  Section 2.01. Issuance and Designation. A Series of Senior
Debt Securities which shall be designated as the Company's "5.25% Senior Notes
due 2015" 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
$450,000,000, 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 $450,000,000 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, 2001 Bryan Street, Floor 11, Dallas, Texas 75201.
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

                                       3
<PAGE>
such account is received by the Trustee or the Paying Agent no later than 30
calendar days preceding such Interest Payment Date. Unless such designation is
revoked, any such designation made by such Holder with respect to such Note
payable to such Holder will remain in effect with respect to any further
interest payments with respect to such Note payable to such Holder. The Company
will pay any administrative costs imposed by banks in connection with making
interest payments by wire transfer.

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

                                  ARTICLE THREE

                              Additional Covenants

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

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

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

                                       4
<PAGE>
                           (ii) any Lien created by a subsidiary of the Company
                  in favor of the Company or any wholly-owned subsidiary;

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

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

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

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

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

                           (viii) any Lien imposed by law.

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

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

                                  ARTICLE FOUR

                                   Defeasance

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

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

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

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

                  (1) the Company shall irrevocably have deposited or caused to
         be deposited with the Trustee under the terms of an irrevocable trust
         agreement in form and substance satisfactory to the Trustee, as trust
         funds in trust solely for the benefit of the Holders of such Notes for
         that purpose, money or direct non-callable obligations of, or
         non-callable obligations guaranteed by, the United States of America
         for the payment of which guarantee or obligation the full faith and
         credit of the United States is pledged ("U.S. Government Obligations")
         maturing as to principal and interest in such amounts and at such times
         as are sufficient, as verified in a Certificate of a Firm of
         Independent Public Accountants, without consideration of any
         reinvestment of such interest, to pay principal of and interest on the
         outstanding Notes to maturity or redemption as the case may be,
         provided that the Trustee or any paying agent shall have been
         irrevocably instructed to apply such money or the proceeds of such U.S.
         Government Obligations to the payment of said principal and interest
         with respect to the Notes. The Company may make an irrevocable deposit
         pursuant to this Section 4.04 only if at such time the Company shall

         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

         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

         representing such deposits or by the Trustee for such trust funds 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

         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.

         obligations in Sections 2.06, 2.08, 5.01, 5.02, 5.05, 6.01, 8.06, 8.10,

                            [FORM OF REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Senior Debt
Securities of the Company designated as its ___% Senior Notes due 20__ (herein
called the "Notes"), issued and to be issued in one or more Series under an
Indenture dated as of October 1, 1998 (herein called the "Indenture") between
the Company and JPMorgan Chase Bank, N.A. (f/k/a The Chase Manhattan Bank), as
Trustee (herein called the "Trustee," which term includes any successor Trustee
under the Indenture), to which Indenture and all indentures supplemental thereto
(including the Indenture Supplement dated as of _______ ___, 2005 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
______________, 2005, or from and including the most recent Interest Payment
Date to which interest has been paid or duly provided for, to but excluding the
particular Interest Payment Date or the Maturity Date. Interest on this Note
will be computed and paid on the basis of a 360-day year of twelve 30-day
months.

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

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

                                       4
<PAGE>
registered as such at the close of business on the relevant Regular Record Date
or Special Record Date, as the case may be, according to their terms and the
provisions of the Indenture.

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

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

                  "Independent Investment Banker" means Citigroup Global Markets
Inc. or J.P. Morgan Securities Inc.

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

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

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

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

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

                                       5
<PAGE>
than all the Notes are to be redeemed at the option of the Company, the Trustee
shall select the Notes to be redeemed in whole or in part by random lot.

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

                  In case an Event of Default shall have occurred and be
continuing with respect to the Notes, the principal hereof may be declared, and
upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture. The Indenture
provides that in certain events such declaration and its consequences may be
waived by the Holders of a majority in aggregate principal amount of the Notes
then outstanding. An Event of Default with respect to the Senior Debt Security
of any other Series issued under the Indenture, including the failure to make
any payment of principal or interest with respect thereto when and as due, will
not necessarily be an Event of Default with respect to the Notes.

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

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

                                       6

purposes, and neither the Company nor the Trustee nor any paying agent nor any
such Senior Debt Security Registrar shall be affected by any notice to the
contrary.

                  No recourse shall be had for the payment of the principal of,
or premium, if any, or interest on, this Note, or for any claim based hereon or
otherwise in respect hereof, or based on or in respect of the Indenture or any
indenture supplemental thereto, against any incorporator, stockholder, officer
or director, as such, past, present or future, of the Company or of any
successor corporation, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for

                            The Bank of New York Trust Company, N.A., as Trustee

                            By:__________________________________________
                                        Authorized Officer".

SECTION 2.04. Execution, Authentication, Delivery and Dating.

            Two Officers of the Company shall sign the Securities of each series
on behalf of the Company by manual or facsimile signature. The Company's seal,
if any, shall be impressed, affixed, imprinted or reproduced on the Securities
and may be in facsimile form.

            If an Officer of the Company whose signature is on a Security no
longer holds that office at the time the Security is authenticated, the Security
shall be valid nevertheless.

            A Security shall not be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose until authenticated by the manual
signature of an authorized signatory

                                       10

<PAGE>

of the Trustee, which signature shall be conclusive evidence that the Security
has been authenticated under this Indenture. Notwithstanding the foregoing, if
any Security has been authenticated and delivered hereunder but never issued and
sold by the Company, and the Company delivers that Security to the Trustee for
cancellation as provided in Section 2.13 together with a written statement
(which need not comply with Section 10.05 and need not be accompanied by an
Opinion of Counsel) stating that such Security has never been issued and sold by
the Company, for all purposes of this Indenture that Security shall be deemed
never to have been authenticated and delivered hereunder and shall never be
entitled to the benefits of this Indenture.

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, and the Trustee shall
authenticate and deliver those Securities for original issue on a Company Order
for the authentication and delivery of those Securities or pursuant to such
procedures reasonably acceptable to the Trustee as may be specified from time to
time by Company Order. That order shall specify the amount of the Securities to
be authenticated, the date on which the original issue of Securities is to be
authenticated, the name or names of the initial Holder or Holders and any other
terms of the Securities of that series not otherwise determined. If provided for
in those procedures, that Company Order may authorize (1) authentication and
delivery of Securities of that series for original issue from time to time, with
certain terms (including, without limitation, the Maturity date or dates,
original issue date or dates and interest rate or rates) that differ from
Security to Security and (2) may authorize authentication and delivery pursuant
to oral or electronic instructions from the Company or its duly authorized
agent, which instructions shall be promptly confirmed in writing.

            If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Section 2.01, in authenticating those Securities, and accepting the additional
responsibilities under this Indenture in relation to those Securities, the
Trustee shall be entitled to receive (in addition to the Company Order referred
to above and the other documents required by Section 10.04), and (subject to
Section 7.01) shall be fully protected in relying on,

            (a) an Officers' Certificate setting forth the Board Resolution and,
if applicable, an appropriate record of any action taken pursuant thereto, as
contemplated by the last paragraph of Section 2.01; and

            (b) an Opinion of Counsel to the effect that:

                  (i)   if the form of those Securities has been established by
                        or pursuant to Board Resolution, as is permitted by
                        Section 2.01, that such form has been established in
                        conformity with the provisions of this Indenture;

                  (ii)  if the terms of those Securities have been established
                        by or pursuant to Board Resolution, as is permitted by
                        Section 2.01, that

                                       11

<PAGE>

                        such terms have been established in conformity with the
                        provisions of this Indenture; and

                  (iii) those Securities, when authenticated and delivered by
                        the Trustee and issued by the Company in the manner and
                        subject to any conditions specified in that Opinion of
                        Counsel, will constitute valid and binding obligations
                        of the Company, enforceable against the Company in
                        accordance with their terms, except as the
                        enforceability thereof may be limited by applicable
                        bankruptcy, insolvency, reorganization, moratorium,
                        fraudulent conveyance or other similar laws in effect
                        from time to time affecting the rights of creditors
                        generally, and the application of general principles of
                        equity (regardless of whether that enforceability is
                        considered in a proceeding in equity or at law).

            If all the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver an Officers' Certificate and Opinion
of Counsel at the time of issuance of each such Security, but that Officers'
Certificate and Opinion of Counsel shall be delivered at or before the time of
issuance of the first Security of the series to be issued.

            The Trustee shall not be required to authenticate those Securities
if the issuance of those Securities pursuant to this Indenture would affect the
Trustee's own rights, duties or immunities under the Securities and this
Indenture or otherwise in a manner not reasonably acceptable to the Trustee.

            The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities. Unless limited by the terms of that
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by that agent. An authenticating agent has the
same rights as an Agent to deal with the Company or an Affiliate of the Company.

            Each Security shall be dated the date of its authentication.

SECTION 2.05 Registrar and Paying Agent.

            The Company shall maintain an office or agency for each series of
Securities where Securities of that series may be presented for registration of
transfer or exchange ("Registrar") and an office or agency where Securities of
that series may be presented for payment ("Paying Agent"). The Registrar shall
keep a register of the Securities of that series and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "Registrar" includes any co-registrar, and
the term "Paying Agent" includes any additional paying agent.

            The Company shall enter into an appropriate agency agreement with
any Registrar or Paying Agent not a party to this Indenture. The agreement shall
implement the provisions of this Indenture that relate to that Agent. The
Company shall notify the Trustee of

                                       12

<PAGE>

the name and address of any Agent not a party to this Indenture. The Company may
change any Paying Agent or Registrar without notice to any Holder. If the
Company fails to appoint or maintain another entity as Registrar or Paying
Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may
act as Paying Agent or Registrar.

            The Company initially appoints the Trustee as Registrar and Paying
Agent.

SECTION 2.06 Paying Agent to Hold Money in Trust.

            With respect to each series of Securities, the Company shall require
each Paying Agent other than the Trustee to agree in writing that the Paying
Agent will hold in trust for the benefit of Holders of Securities of that series
or the Trustee all money held by the Paying Agent for the payment of principal
of, premium, if any, or interest on or any Additional Amounts with respect to
Securities of that series and will notify the Trustee of any default by the
Company in making any such payment. While any such default continues, the
Trustee may require a Paying Agent to pay all money held by it to the Trustee
and to account for any funds disbursed. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and to account for any
funds disbursed. Upon payment over to the Trustee and upon accounting for any
funds disbursed, the Paying Agent (if other than the Company or a Subsidiary of
the Company) shall have no further liability for the money. If the Company or a
Subsidiary of the Company acts as Paying Agent with respect to a series of
Securities, it shall segregate and hold in a separate trust fund for the benefit
of the Holders of Securities of that series all money held by it as Paying
Agent. Each Paying Agent shall otherwise comply with TIA Section 317(b).

SECTION 2.07 Holder Lists.

            The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders of each series of Securities and shall otherwise comply with TIA Section
312(a). If the Trustee is not the Registrar with respect to a series of
Securities, the Company shall furnish to the Trustee at least five Business Days
before each Interest Payment Date with respect to that series of Securities, and
at such other times as the Trustee may request in writing, a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of Holders of the Securities of that series, and the Company shall
otherwise comply with TIA Section 312(a).

SECTION 2.08 Transfer and Exchange.

            Except as set forth in Section 2.17 or as may be provided pursuant
to Section 2.01, when Securities of any series are presented to the Registrar
with the request to register the transfer of those Securities or to exchange
those Securities for an equal principal amount of Securities of the same series
of like tenor and of other authorized denominations, the Registrar shall
register the transfer or make the exchange as requested if its requirements and
the requirements of this Indenture for those transactions are met; provided,
however, that the Securities presented or surrendered for registration of
transfer or exchange shall be duly endorsed or accompanied by a written
instruction of transfer in form reasonably satisfactory to

                                       13

<PAGE>

the Registrar duly executed by the Holder thereof or by his attorney, duly
authorized in writing, on which instruction the Registrar can rely.

            To permit registrations of transfers and exchanges, the Company
shall execute and the Trustee shall authenticate Securities at the Registrar's
written request and submission of the Securities (other than Global Securities).
No service charge shall be made to a Holder for any registration of transfer or
exchange (except as otherwise expressly permitted herein), but the Company may
require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than such transfer
tax or similar governmental charge payable on exchanges pursuant to Section
2.12, 3.07 or 9.05). The Trustee shall authenticate Securities in accordance
with the provisions of Section 2.04. Notwithstanding any other provisions of
this Indenture to the contrary, the Company shall not be required to register
the transfer or exchange of (a) any Security selected for redemption in whole or
in part pursuant to Article III, except the unredeemed portion of any Security
being redeemed in part or (b) any Security during the period beginning 15
Business Days before the mailing of notice of any offer to repurchase Securities
of the series required pursuant to the terms thereof or of redemption of
Securities of a series to be redeemed and ending at the close of business on the
date of mailing.

SECTION 2.09 Replacement Securities.

            If any mutilated Security is surrendered to the Trustee, or if the
Holder of a Security claims that the Security has been destroyed, lost or stolen
and the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of that Security, the Company shall issue and the
Trustee shall authenticate a replacement Security of the same series if the
Trustee's requirements are met. If any such mutilated, destroyed, lost or stolen
Security has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay that Security. If
required by the Trustee or the Company, the Holder must furnish an indemnity
bond that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee, any Agent or any authenticating agent from any
loss that any of them may suffer if a Security is replaced. The Company and the
Trustee may charge the Holder for their expenses in replacing a Security.

            Every replacement Security is an additional obligation of the
Company.

SECTION 2.10 Outstanding Securities.

            The Securities outstanding at any time are all the Securities
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Security
effected by the Trustee hereunder and those described in this Section 2.10 as
not outstanding.

            If a Security is replaced pursuant to Section 2.09, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

                                       14

<PAGE>

            If the principal amount of any Security is considered paid under
Section 4.01, it ceases to be outstanding and interest on it ceases to accrue.

            A Security does not cease to be outstanding because the Company or
an Affiliate of the Company holds the Security.

SECTION 2.11 Original Issue Discount, Foreign-Currency Denominated and Treasury
             Securities.

            In determining whether the Holders of the required principal amount
of Securities have concurred in any direction, amendment, supplement, waiver or
consent, (a) the principal amount of an Original Issue Discount Security shall
be the principal amount thereof that would be due and payable as of the date of
that determination upon acceleration of the Maturity thereof pursuant to Section
6.02, (b) the principal amount of a Security denominated in a foreign currency
shall be the Dollar equivalent, as determined by the Company by reference to the
noon buying rate in The City of New York for cable transfers for that currency,
as that rate is certified for customs purposes by the Federal Reserve Bank of
New York (the "Exchange Rate") on the date of original issuance of that
Security, of the principal amount (or, in the case of an Original Issue Discount
Security, the Dollar equivalent, as determined by the Company by reference to
the Exchange Rate on the date of original issuance of that Security, of the
amount determined as provided in (a) above), of that Security and (c) Securities
owned by the Company or any other obligor on the Securities or any Affiliate of
the Company or of that other obligor shall be disregarded, except that, for the
purpose of determining whether the Trustee shall be protected in relying on any
such direction, amendment, supplement, waiver or consent, only Securities that
the Trustee actually knows are so owned shall be so disregarded.

SECTION 2.12 Temporary Securities.

            Until definitive Securities of any series are ready for delivery,
the Company may prepare and the Trustee shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of definitive
Securities, but may have variations that the Company considers appropriate for
temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Securities in exchange for temporary
Securities. Until so exchanged, the temporary Securities shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities.

SECTION 2.13 Cancellation.

            The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for registration of transfer, exchange,
payment or redemption or for credit against any sinking fund payment. The
Trustee shall cancel all Securities surrendered for registration of transfer,
exchange, payment, redemption, replacement or cancellation or for credit against
any sinking fund. Unless the Company shall direct in writing that canceled
Securities be returned to it, after written notice to the Company all canceled
Securities held by the Trustee shall be disposed of in accordance with the usual
disposal procedures of the Trustee, and the Trustee

                                       15

<PAGE>

shall maintain a record of their disposal. The Company may not issue new
Securities to replace Securities that have been paid or that have been delivered
to the Trustee for cancellation.

SECTION 2.14 Payments; Defaulted Interest.

            Unless otherwise provided as contemplated by Section 2.01 with
respect to the Securities of any series, interest (except defaulted interest) on
any Security that is payable, and is punctually paid or duly provided for, on
any Interest Payment Date shall be paid to the Persons who are registered
Holders of that Security at the close of business on the record date next
preceding that Interest Payment Date, even if those Securities are canceled
after that record date and on or before that Interest Payment Date. Unless
otherwise provided with respect to the Securities of any series, the Company
will pay the principal of, premium (if any) and interest on and any Additional
Amounts with respect to the Securities in Dollars. Those amounts shall be
payable at the offices of the Trustee, provided that at the option of the
Company, the Company may pay those amounts (1) by wire transfer with respect to
Global Securities or (2) by check payable in that money mailed to a Holder's
registered address with respect to any Securities.

            If the Company defaults in a payment of interest on the Securities
of any series, it shall pay the defaulted interest in any lawful manner plus, to
the extent lawful, interest on the defaulted interest, in each case at the rate
provided in the Securities of that series and in Section 4.01. The Company may
pay the defaulted interest to the Persons who are Holders on a subsequent
special record date. At least 15 days before any special record date selected by
the Company, the Company (or the Trustee, in the name of and at the expense of
the Company upon 20 days' prior written notice from the Company setting forth
that record date and the interest amount to be paid) shall mail to Holders of
any such series of Securities a notice that states the special record date, the
related payment date and the amount of that interest to be paid.

SECTION 2.15 Persons Deemed Owners.

            The Company, the Trustee, any Agent and any authenticating agent may
treat the Person in whose name any Security is registered as the owner of that
Security for the purpose of receiving payments of principal of, premium (if any)
or interest on, or any Additional Amounts with respect to that Security and for
all other purposes. None of the Company, the Trustee, any Agent or any
authenticating agent shall be affected by any notice to the contrary.

SECTION 2.16 Computation of Interest.

            Except as otherwise specified as contemplated by Section 2.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a year comprising twelve 30-day months.

SECTION 2.17 Global Securities; Book-Entry Provisions.

            If Securities of a series are issuable in global form as a Global
Security, as contemplated by Section 2.01, then, notwithstanding clause (10) of
Section 2.01 and the provisions of Section 2.02, any such Global Security shall
represent those of the outstanding

                                       16

<PAGE>

Securities of that series as shall be specified therein and may provide that it
shall represent the aggregate amount of outstanding Securities from time to time
endorsed thereon and that the aggregate amount of outstanding Securities
represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges or redemptions. Any endorsement of a Global
Security to reflect the amount, or any increase or decrease in the amount, of
outstanding Securities represented thereby shall be made by the Trustee (i) in
such manner and upon instructions given by such Person or Persons as shall be
specified in that Security or in a Company Order to be delivered to the Trustee
pursuant to Section 2.04 or (ii) otherwise in accordance with written
instructions or such other written form of instructions as is customary for the
Depositary for that Security, from that Depositary or its nominee on behalf of
any Person having a beneficial interest in that Global Security. Subject to the
provisions of Section 2.04 and, if applicable, Section 2.12, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon instructions given by the Person or Persons specified in that Security or
in the applicable Company Order. With respect to the Securities of any series
that are represented by a Global Security, the Company authorizes the execution
and delivery by the Trustee of a letter of representations or other similar
agreement or instrument in the form customarily provided for by the Depositary
appointed with respect to that Global Security. Any Global Security may be
deposited with the Depositary or its nominee, or may remain in the custody of
the Trustee or the Security Custodian therefor pursuant to a FAST Balance
Certificate Agreement or similar agreement between the Trustee and the
Depositary. If a Company Order has been, or simultaneously is, delivered, any
instructions by the Company with respect to endorsement or delivery or
redelivery of a Security in global form shall be in writing but need not comply
with Section 10.05 and need not be accompanied by an Opinion of Counsel.

            Members of, or participants in, the Depositary ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depositary, or the Trustee or the Security Custodian
as its custodian, or under that Global Security, and the Depositary may be
treated by the Company, the Trustee or the Security Custodian and any agent of
the Company, the Trustee or the Security Custodian as the absolute owner of that
Global Security for all purposes whatsoever. Notwithstanding the foregoing, (i)
the registered holder of a Global Security of any series may grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action that a Holder of
Securities of that series is entitled to take under this Indenture or the
Securities of that series and (ii) nothing herein shall prevent the Company, the
Trustee or the Security Custodian or any agent of the Company, the Trustee, or
the Security Custodian from giving effect to any written certification, proxy or
other authorization furnished by the Depositary or shall impair, as between the
Depositary and its Agent Members, the operation of customary practices governing
the exercise of the rights of a beneficial owner of any Security.

            Notwithstanding Section 2.08, and except as otherwise provided
pursuant to Section 2.01, transfers of a Global Security shall be limited to
transfers of that Global Security in whole, but not in part, to the Depositary,
its successors or their respective nominees. Interests of beneficial owners in a
Global Security may be transferred in accordance with the rules and procedures
of the Depositary. Securities of any series shall be transferred to all
beneficial owners of a Global Security of that series in exchange for their
beneficial interests in that Global

                                       17

<PAGE>

Security if, and only if, either (1) the Depositary notifies the Company that it
is unwilling or unable to continue as Depositary for that Global Security and a
successor Depositary is not appointed by the Company within 90 days of that
notice, (2) an Event of Default has occurred with respect to that series and is
continuing and the Registrar has received a request from the Depositary to issue
Securities of that series in lieu of all or a portion of that Global Security
(in which case the Company shall deliver Securities of that series within 30
days of that request) or (3) the Company determines not to have the Securities
of that series represented by a Global Security.

            In connection with any transfer of a portion of the beneficial
interests in a Global Security to beneficial owners pursuant to this Section
2.17, the Registrar shall reflect on its books and records the date and a
decrease in the principal amount of the Global Security in an amount equal to
the principal amount of the beneficial interest in the Global Security to be
transferred, and the Company shall execute, and the Trustee on receipt of a
Company Order for the authentication and delivery of Securities shall
authenticate and deliver, one or more Securities of the same series of like
tenor and amount.

            In connection with the transfer of all the beneficial interests in a
Global Security of any series to beneficial owners pursuant to this Section
2.17, the Global Security shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, and the Trustee shall authenticate
and deliver, to each beneficial owner identified by the Depositary in exchange
for its beneficial interest in the Global Security, an equal aggregate principal
amount of Securities of that series of authorized denominations.

            Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records relating to, or payments made on account
of, Securities by the Depositary, or for maintaining, supervising or reviewing
any records of the Depositary relating to those Securities. Neither the Company
nor the Trustee shall be liable for any delay by the related Global Security
Holder or the Depositary in identifying the beneficial owners, and each such
Person may conclusively rely on, and shall be protected in relying on,
instructions from that Global Security Holder or the Depositary for all purposes
(including with respect to the registration and delivery, and the respective
principal amounts, of the Securities to be issued).

            The provisions of the last sentence of the third paragraph of
Section 2.04 shall apply to any Global Security if that Global Security was
never issued and sold by the Company and the Company delivers to the Trustee the
Global Security together with written instructions (which need not comply with
Section 10.05 and need not be accompanied by an Opinion of Counsel) with regard
to the cancellation or reduction in the principal amount of Securities
represented thereby, together with the written statement contemplated by the
last sentence of the third paragraph of Section 2.04.

            Notwithstanding the provisions of Sections 2.03 and 2.14, unless
otherwise specified as contemplated by Section 2.01 with respect to Securities
of any series, payment of principal of and premium (if any) and interest on and
any Additional Amounts with respect to any Global Security shall be made to the
Person or Persons specified therein.

                                   ARTICLE III
                                   REDEMPTION

SECTION 3.01 Applicability of Article.

            Securities of any series that are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 2.01 for Securities of any
series) in accordance with this Article III.

SECTION 3.02 Notice to the Trustee.

            If the Company elects to redeem Securities of any series pursuant to
this Indenture, it shall notify the Trustee of the Redemption Date and principal
amount of Securities of that series to be redeemed. The Company shall so notify
the Trustee at least 45 days before the Redemption Date (unless a shorter notice
shall be satisfactory to the Trustee) by delivering to the Trustee an Officers'
Certificate stating that the redemption will comply with the provisions of this
Indenture and of the Securities of that series. Any such notice may be canceled
at any time prior to the mailing of that notice of redemption to any Holder of
the Securities of that series and shall thereupon be void and of no effect.

SECTION 3.03 Selection of Securities To Be Redeemed.

            If less than all the Securities of any series are to be redeemed
(unless all of the Securities of that series of a specified tenor are to be
redeemed), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the outstanding
Securities of that series (and tenor) not previously called for redemption,
either pro rata, by lot or by such other method as the Trustee shall deem fair
and appropriate. That redemption may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of that series of a denomination larger than the minimum authorized denomination
for Securities of that series or of the principal amount of Global Securities of
that series.

            The Trustee shall promptly notify the Company and the Registrar in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

            For purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Securities of any series
shall relate, in the case of any of the Securities redeemed or to be redeemed
only in part, to the portion of the principal amount thereof which has been or
is to be redeemed.

SECTION 3.04 Notice of Redemption.

            Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of

                                       19

<PAGE>

Securities of a series to be redeemed, at the address of that Holder appearing
in the register of Securities for that series maintained by the Registrar.

            All notices of redemption shall identify the Securities to be
redeemed and shall state:

            (1) the Redemption Date;

            (2) the Redemption Price;

            (3) that, unless the Company defaults in making the redemption
      payment, interest on Securities called for redemption ceases to accrue on
      and after the Redemption Date, and the only remaining right of the Holders
      of those Securities is to receive payment of the Redemption Price on
      surrender to the Paying Agent of the Securities redeemed;

            (4) if any Security is to be redeemed in part, the portion of the
      principal amount thereof to be redeemed and that on and after the
      Redemption Date, on surrender for cancellation of that Security to the
      Paying Agent, a new Security or Securities in the aggregate principal
      amount equal to the unredeemed portion thereof will be issued without
      charge to the Holder;

            (5) that Securities called for redemption must be surrendered to the
      Paying Agent to collect the Redemption Price and the name and address of
      the Paying Agent;

            (6) that the redemption is for a sinking or analogous fund, if that
      is the case; and

            (7) the CUSIP number, if any, relating to those Securities.

            Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's written request,
by the Trustee in the name and at the expense of the Company.

SECTION 3.05 Effect of Notice of Redemption.

            Once notice of redemption is mailed, Securities called for
redemption become due and payable on the Redemption Date and at the Redemption
Price. Upon surrender to the Paying Agent, those Securities called for
redemption shall be paid at the Redemption Price, but interest installments
whose maturity is on or prior to that Redemption Date will be payable on the
relevant Interest Payment Dates to the Holders of record at the close of
business on the relevant record dates specified pursuant to Section 2.01.

                                       20

SECTION 3.06 Deposit of Redemption Price.

            On or prior to any Redemption Date, the Company shall deposit with
the Trustee or the Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 2.06) an amount of
money in same day funds sufficient to pay the Redemption Price of, and (except
if the Redemption Date shall be an Interest Payment Date) accrued interest on
and any Additional Amounts with respect to, the Securities or portions thereof
which are to be redeemed on that date, other than Securities or portions thereof
called for redemption on that date which have been delivered by the Company to
the Trustee for cancellation.

            If the Company complies with the preceding paragraph, then, unless
the Company defaults in the payment of that Redemption Price, interest on the
Securities to be redeemed will cease to accrue on and after the applicable
Redemption Date, whether or not those Securities are presented for payment, and
the Holders of those Securities shall have no further rights with respect to
those Securities except for the right to receive the Redemption Price on
surrender of those Securities. If any Security called for redemption shall not
be so paid on surrender thereof for redemption, the principal of and premium, if
any, any Additional Amounts, and, to the extent lawful, accrued interest thereon
shall, until paid, bear interest from the Redemption Date at the rate specified
pursuant to Section 2.01 or provided in the Securities or, in the case of
Original Issue Discount Securities, their initial yield to maturity.

SECTION 3.07 Securities Redeemed or Purchased in Part.

            Upon surrender to the Paying Agent of a Security to be redeemed in
part, the Company shall execute and the Trustee shall authenticate and deliver
to the Holder of that Security without service charge a new Security or
Securities, of the same series and of any authorized denomination as requested
by that Holder in aggregate principal amount equal to, and in exchange for, the
unredeemed portion of the principal of the Security so surrendered that is not
redeemed.

SECTION 3.08 Purchase of Securities.

            Unless otherwise specified as contemplated by Section 2.01, the
Company and any Affiliate of the Company may at any time purchase or otherwise
acquire Securities in the open market or by private agreement. Any such
acquisition shall not operate as or be deemed for any purpose to be a redemption
of the indebtedness represented by those Securities. Any Securities purchased or
acquired by the Company may be delivered to the Trustee for cancellation and, on
that cancellation, the indebtedness represented thereby shall be deemed to be
satisfied. Section 2.13 shall apply to all Securities so delivered.

SECTION 3.09 Mandatory and Optional Sinking Funds.

            The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of the minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment." Unless otherwise provided by the terms of Securities of
any series, the cash amount of any sinking fund payment may be subject to

                                       21

<PAGE>

reduction as provided in Section 3.10. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of that series and by this Article III.

SECTION 3.10 Satisfaction of Sinking Fund Payments with Securities.

            The Company may deliver outstanding Securities of a series (other
than any previously called for redemption) and may apply as a credit Securities
of a series that have been redeemed either at the election of the Company
pursuant to the terms of those Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of those
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of that series required to be made
pursuant to the terms of that series of Securities; provided that those
Securities have not been previously so credited. Those Securities shall be
received and credited for that purpose by the Trustee at the Redemption Price
specified in those Securities for redemption through operation of the sinking
fund, and the amount of that sinking fund payment shall be reduced accordingly.

SECTION 3.11 Redemption of Securities for Sinking Fund.

            Not less than 45 days prior (unless a shorter period shall be
satisfactory to the Trustee) to each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officers' Certificate of
the Company specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
that is to be satisfied by payment of cash and the portion thereof, if any, that
is to be satisfied by delivery of or by crediting Securities of that series
pursuant to Section 3.10 and will also deliver to the Trustee any Securities to
be so delivered. Failure of the Company to timely deliver that Officers'
Certificate and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute the election of the Company (i) that
the mandatory sinking fund payment for that series due on the next succeeding
sinking fund payment date shall be paid entirely in cash without the option to
deliver or credit Securities of that series in respect thereof and (ii) that the
Company will make no optional sinking fund payment with respect to that series
as provided in this Section.

            If the sinking fund payment or payments (mandatory or optional or
both) to be made in cash on the next succeeding sinking fund payment date plus
any unused balance of any preceding sinking fund payments made in cash shall
exceed $100,000 (or the Dollar equivalent thereof based on the applicable
Exchange Rate on the date of original issue of the applicable Securities) or a
lesser sum if the Company shall so request with respect to the Securities of any
particular series, that cash shall be applied on the next succeeding sinking
fund payment date to the redemption of Securities of that series at the sinking
fund redemption price together with accrued interest to the date fixed for
redemption. If that amount shall be $100,000 (or the Dollar equivalent thereof
as aforesaid) or less and the Company makes no such request, then it shall be
carried over until a sum in excess of $100,000 (or the Dollar equivalent thereof
as aforesaid) is available. Not less than 30 days before each such sinking fund
payment date, the Trustee shall select the Securities to be redeemed on that
sinking fund payment date in the manner specified in Section 3.03 and cause
notice of the redemption thereof to be given in the name of and at the

                                       22

<PAGE>

expense of the Company in the manner provided in Section 3.04. That notice
having been duly given, the redemption of those Securities shall be made on the
terms and in the manner stated in Sections 3.05, 3.06 and 3.07.

                                   ARTICLE IV
                                    COVENANTS

SECTION 4.01 Payment of Securities.

            The Company shall pay the principal of, premium (if any) and
interest on and any Additional Amounts with respect to the Securities of each
series on the dates and in the manner provided in the Securities of that series
and in this Indenture. Principal, premium, interest and any Additional Amounts
shall be considered paid on the date due if the Paying Agent, other than the
Company or a Subsidiary of the Company, holds on that date money deposited by
the Company designated for and sufficient to pay all principal, premium (if
any), interest and any Additional Amounts then due.

            The Company shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal of and premium (if
any) on Securities of any series, at a rate equal to the then applicable
interest rate on the Securities of that series to the extent lawful; and it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest on and any overdue payments
of Additional Amounts with respect to Securities of that series (without regard
to any applicable grace period) at the same rate to the extent lawful.

SECTION 4.02 Maintenance of Office or Agency.

            The Company will maintain in each Place of Payment for any series of
Securities an office or agency (which may be an office of the Trustee, the
Registrar or the Paying Agent) where Securities of that series may be presented
for registration of transfer or exchange, where Securities of that series may be
presented for payment and where notices and demands to or on the Company in
respect of the Securities of that series and this Indenture may be served.
Unless otherwise designated by the Company by written notice to the Trustee,
that office or agency shall be the office of the Trustee in the Borough of
Manhattan, The City of New York, which on the date hereof is located at 101
Barclay Street, New York, New York 10286. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of that
office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, those presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee.

            The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all those purposes and may from time to time rescind
those designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for those

                                       23

<PAGE>

purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

SECTION 4.03 SEC Reports; Financial Statements.

            (a) The Company shall file with the Trustee, within 15 days after it
files the same with the SEC, copies of the annual reports and the information,
documents and other reports (or copies of those portions of any of the foregoing
as the SEC may by rules and regulations prescribe) that the Company is required
to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The
Company shall also comply with the provisions of TIA 314(a).

            (b) If the Company is not subject to the requirements of Section 13
or 15(d) of the Exchange Act, the Company shall furnish to all Holders of Rule
144A Securities and prospective purchasers of Rule 144A Securities designated by
the Holders of Rule 144A Securities, promptly on their request, the information
required to be delivered pursuant to Rule 144A(d)(4) promulgated under the
Securities Act of 1933, as amended.

SECTION 4.04 Compliance Certificate.

            (a) The Company shall deliver to the Trustee, within 120 days after
the end of each fiscal year of the Company, a statement signed by an Officer of
the Company, which need not constitute an Officers' Certificate, complying with
TIA Section 314(a)(4) and stating that, in the course of performance by the
signing Officer of the Company of his or her duties as such Officer of the
Company, he or she would normally obtain knowledge of the keeping, observing,
performing and fulfilling by the Company of its obligations under this
Indenture, and further stating that, to the best of his or her knowledge, the
Company has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and is not in default in the performance or
observance of any of the terms, provisions and conditions hereof (or, if a
Default or Event of Default shall have occurred, describing all such Defaults or
Events of Default of which that Officer may have knowledge and what action the
Company is taking or proposes to take with respect thereto).

            (b) The Company shall, so long as Securities of any series are
outstanding, deliver to the Trustee, promptly on any Officer of the Company
becoming aware of any Default or Event of Default under this Indenture, an
Officers' Certificate specifying that Default or Event of Default and what
action the Company is taking or proposes to take with respect thereto.

SECTION 4.05 Existence.

            Subject to Article V hereof, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect its
existence and the existence of each of its Subsidiaries and all rights (charter
and statutory) of the Company and its Subsidiaries, provided that the Company
shall not be required to preserve the existence of any Subsidiary of the Company
or any such right if the Company shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company and its
Subsidiaries taken as a

                                       24

<PAGE>

whole and that the loss thereof would not have a material adverse effect on the
business, operations, assets or financial condition of the Company and its
Subsidiaries taken as a whole and would not have any material adverse effect on
the payment and performance of the obligations of the Company under the
Securities and this Indenture.

SECTION 4.06 Waiver of Stay, Extension or Usury Laws.

            The Company covenants (to the extent that it may lawfully do so)
that it will not at any time insist on, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any
usury law or other law that would prohibit or forgive the Company from paying
all or any portion of the principal of or interest on the Securities as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture; and (to the
extent that it may lawfully do so) the Company hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.

SECTION 4.07 Additional Amounts.

            If the Securities of a series expressly provide for the payment of
Additional Amounts, the Company will pay to the Holder of any Security of that
series Additional Amounts as expressly provided therein. Whenever in this
Indenture there is mentioned, in any context, the payment of the principal of or
any premium or interest on, or in respect of, any Security of any series or the
net proceeds received from the sale or exchange of any Security of any series,
that mention shall be deemed to include mention of the payment of Additional
Amounts provided for in this Section 4.07 to the extent that, in that context,
Additional Amounts are, were or would be payable in respect thereof pursuant to
the provisions of this Section 4.07, and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in those provisions hereof where that
express mention is not made.

            Unless otherwise provided pursuant to Section 2.01 with respect to
Securities of any series, if the Securities of a series provide for the payment
of Additional Amounts, at least ten days prior to the first Interest Payment
Date with respect to that series of Securities (or if the Securities of that
series will not bear interest prior to Maturity, the first day on which a
payment of principal and any premium is made), and at least ten days prior to
each date of payment of principal and any premium or interest if there has been
any change with respect to the matters set forth in the below-mentioned
Officers' Certificate, the Company shall furnish the Trustee and the Company's
principal Paying Agent or Paying Agents, if other than the Trustee, with an
Officers' Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether that payment of principal of and any premium or interest on the
Securities of that series shall be made to Holders of Securities of that series
who are United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of that
series. If any such withholding shall be required, then that Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on those payments to those Holders of

                                       25

<PAGE>

Securities, and the Company will pay to that Paying Agent the Additional Amounts
required by this Section. The Company covenants to indemnify the Trustee and any
Paying Agent for and to hold them harmless against any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officers' Certificate furnished pursuant to this Section 4.07.

SECTION 5.01 Limitations on Mergers, Consolidations and Other Transactions.

            The Company shall not, in any transaction or series of related
transactions, consolidate with any other Person into, or merge into, any other
Person, or sell, lease, convey, transfer or otherwise dispose of its assets
substantially as an entirety to any Person, unless:

            (1) the Person formed by that consolidation or into which the
      Company is merged, or to which that sale, lease, conveyance, transfer or
      other disposition shall be made (collectively, the "Successor"), expressly
      assumes by supplemental indenture the due and punctual payment of the
      principal of (and premium, if any) and interest on and Additional Amounts
      with respect to all the Securities and the performance of the Company's
      covenants and obligations under this Indenture and the Securities;

            (2) immediately after giving effect to that transaction or series of
      related transactions, no Default or Event of Default shall have occurred
      and be continuing; and

            (3) the Company delivers to the Trustee an Officers' Certificate and
      an Opinion of Counsel, each stating that the transaction and that
      supplemental indenture comply with this Indenture.

SECTION 5.02 Successor Person Substituted.

            Upon any consolidation or merger of the Company or any sale, lease,
conveyance, transfer or other disposition of the assets of the Company
substantially as an entirety in accordance with Section 5.01, any Successor
formed by that consolidation or into or with which the Company is merged or to
which that sale, lease, conveyance, transfer or other disposition is made shall
succeed to, and be substituted for, and may exercise every right and power of
the Company under this Indenture and the Securities with the same effect as if
that Successor had been named as the Company herein and the predecessor Company,
in the case of a sale, conveyance, transfer or other disposition, shall be
released from all obligations under this Indenture and the Securities.

                              DEFAULTS AND REMEDIES

SECTION 6.01 Events of Default.

            Unless either inapplicable to a particular series or specifically
deleted or modified in or pursuant to the supplemental indenture or Board
Resolution establishing that series of Securities or in the form of Security for
that series, an "Event of Default," wherever used herein with respect to
Securities of any series, occurs if:

            (1) the Company defaults in the payment of interest on or any
      Additional Amounts with respect to any Security of that series when the
      same becomes due and payable and that default continues for a period of 30
      days;

            (2) the Company defaults in the payment of (A) the principal of any
      Security of that series at its Maturity or (B) premium (if any) on any
      Security of that series when the same becomes due and payable, regardless
      of whether such payment became due because of maturity, redemption,
      acceleration or otherwise, or is required by any sinking fund established
      with respect to such series;

            (3) the Company fails to comply with any of its other covenants or
      agreements in, or provisions of, the Securities of that series or this
      Indenture (other than an agreement, covenant or provision that has
      expressly been included in this Indenture solely for the benefit of one or
      more series of Securities other than that series) which shall not have
      been remedied within the specified period after written notice, as
      specified in the last paragraph of this Section 6.01;

            (4) the Company pursuant to or within the meaning of any Bankruptcy
      Law:

                  (A) commences a voluntary case,

                  (B) consents to the entry of an order for relief against it in
            an involuntary case,

                  (C) consents to the appointment of a Bankruptcy Custodian of
            it or for all or substantially all of its property, or

                  (D) makes a general assignment for the benefit of its
            creditors;

            (5) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that remains unstayed and in effect for 90 days
      and that:

                  (A) is for relief against the Company as debtor in an
            involuntary case,

                  (B) appoints a Bankruptcy Custodian of the Company or a
            Bankruptcy Custodian for all or substantially all of the property of
            the Company, or

                  (C) orders the liquidation of the Company;

                                       27

<PAGE>

            (6) the Company defaults with respect to its Debt (other than the
      Securities for that series) in an aggregate principal amount in excess of
      that dollar amount specified in the supplemental indenture for the
      Securities, which

                  (A) consists of the failure to make any payment at maturity,
            or

                  (B) results in acceleration of the maturity of such Debt; or

            (7) any other Event of Default provided with respect to Securities
      of that series occurs.

            The term "Bankruptcy Custodian" means any receiver, trustee,
assignee, liquidator or similar official under any Bankruptcy Law.

            The Trustee shall not be deemed to know or have notice of a Default
unless a Trust Officer at the Corporate Trust Office of the Trustee receives
written notice at the Corporate Trust Office of the Trustee of that Default with
specific reference to that Default.

            When a Default is cured, it ceases.

            Notwithstanding the foregoing provisions of this Section 6.01, if
the principal of, premium (if any) or interest on or Additional Amounts with
respect to any Security is payable in a currency or currencies (including a
composite currency) other than Dollars and such currency or currencies are not
available to the Company for making payment thereof due to the imposition of
exchange controls or other circumstances beyond the control of the Company (a
"Conversion Event"), the Company will be entitled to satisfy its obligations to
Holders of the Securities by making that payment in Dollars in an amount equal
to the Dollar equivalent of the amount payable in such other currency, as
determined by the Company by reference to the Exchange Rate on the date of that
payment, or, if that rate is not then available, on the basis of the most
recently available Exchange Rate. Notwithstanding the foregoing provisions of
this Section 6.01, any payment made under such circumstances in Dollars where
the required payment is in a currency other than Dollars will not constitute an
Event of Default under this Indenture.

            Promptly after the occurrence of a Conversion Event, the Company
shall give written notice thereof to the Trustee; and the Trustee, promptly
after receipt of that notice, shall give notice thereof in the manner provided
in Section 10.02 to the Holders. Promptly after the making of any payment in
Dollars as a result of a Conversion Event, the Company shall give notice in the
manner provided in Section 10.02 to the Holders, setting forth the applicable
Exchange Rate and describing the calculation of those payments.

            A Default under clause (3) of this Section 6.01 is not an Event of
Default until the Trustee notifies the Company, or the Holders of at least 25%
in principal amount of the then outstanding Securities of the series affected by
that Default, or, if outstanding Securities of other series are affected by that
Default, then at least 25% in principal amount of the then outstanding
Securities so affected, notify the Company and the Trustee, of the Default, and
the Company fails to cure the Default within the period of days specified in the
applicable indenture

                                       28

<PAGE>

supplement after receipt of the notice. The notice must specify the Default,
demand that it be remedied and state that the notice is a "Notice of Default."

SECTION 6.02 Acceleration.

            If an Event of Default with respect to any Securities of any series
at the time outstanding (other than an Event of Default specified in clause (4)
or (5) of Section 6.01 hereof) occurs and is continuing, the Trustee by notice
to the Company, or the Holders of at least 25% in principal amount of the then
outstanding Securities of the series affected by that default (or, in the case
of an Event of Default described in clause (3) of Section 6.01, if outstanding
Securities of other series are affected by that Default, then at least 25% in
principal amount of the then outstanding Securities so affected) by notice to
the Company and the Trustee, may declare the principal of (or, if any of those
Securities are Original Issue Discount Securities, that portion of the principal
amount as may be specified in the terms of that series) and all accrued and
unpaid interest on all then outstanding Securities of that series or of all
series, as the case may be, to be due and payable. Upon any such declaration,
the amounts due and payable on those Securities shall be due and payable
immediately. If an Event of Default specified in clause (4) or (5) of Section
6.01 hereof occurs, those amounts shall ipso facto become and be immediately due
and payable without any declaration, notice or other act on the part of the
Trustee or any Holder. The Holders of a majority in principal amount of the then
outstanding Securities of the series affected by that default or all series, as
the case may be, by written notice to the Trustee may rescind an acceleration
and its consequences (other than nonpayment of principal of or premium or
interest on or any Additional Amounts with respect to the Securities) if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default with respect to Securities of that series (or of all series,
as the case may be) have been cured or waived, except nonpayment of principal,
premium, interest or any Additional Amounts that has become due solely because
of the acceleration.

SECTION 6.03 Other Remedies.

            If an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may pursue any available remedy to collect
the payment of principal of, or premium, if any, or interest on the Securities
of that series or to enforce the performance of any provision of the Securities
of that series or this Indenture.

            The Trustee may maintain a proceeding with respect to Securities of
any series even if it does not possess any of the Securities of that series or
does not produce any of them in the proceeding. A delay or omission by the
Trustee or any Holder in exercising any right or remedy accruing on an Event of
Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. All remedies are cumulative to the extent
permitted by law.

SECTION 6.04 Waiver of Defaults.

            Subject to Sections 6.07 and 9.02, the Holders of a majority in
principal amount of the then outstanding Securities of any series or of all
series (acting as one class) by notice to

                                       29

<PAGE>

the Trustee may waive an existing or past Default or Event of Default with
respect to that series or all series, as the case may be, and its consequences
(including waivers obtained in connection with a tender offer or exchange offer
for Securities of that series or all series or a solicitation of consents in
respect of Securities of that series or all series, provided that in each case
that offer or solicitation is made to all Holders of then outstanding Securities
of that series or all series (but the terms of that offer or solicitation may
vary from series to series)), except (1) a continuing Default or Event of
Default in the payment of the principal of, or premium, if any, or interest on
or any Additional Amounts with respect to any Security or (2) a continued
Default in respect of a provision that under Section 9.02 cannot be amended or
supplemented without the consent of each Holder affected. Upon any such waiver,
that Default shall cease to exist, and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose of this Indenture; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

SECTION 6.05 Control by Majority.

            With respect to Securities of any series, the Holders of a majority
in principal amount of the then outstanding Securities of that series may direct
in writing the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on it
relating to or arising under an Event of Default described in clause (1), (2) or
(7) of Section 6.01, and with respect to all Securities, the Holders of a
majority in principal amount of all the then outstanding Securities affected may
direct in writing the time, method and place of conducting any proceeding for
any remedy available to the Trustee or exercising any trust or power conferred
on it not relating to or arising under such an Event of Default. However, the
Trustee may refuse to follow any direction that conflicts with applicable law or
this Indenture, that the Trustee determines may be unduly prejudicial to the
rights of other Holders, or that may involve the Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with that direction. Prior to taking any
action hereunder, the Trustee shall be entitled to indemnification satisfactory
to it in its sole discretion from Holders directing the Trustee against all
losses and expenses caused by taking or not taking that action.

SECTION 6.06 Limitations on Suits.

            Subject to Section 6.07 hereof, a Holder of a Security of any series
may pursue a remedy with respect to this Indenture or the Securities of that
series only if:

            (1) the Holder gives to the Trustee written notice of a continuing
      Event of Default with respect to that series;

            (2) the Holders of at least 25% in principal amount of the then
      outstanding Securities of that series make a written request to the
      Trustee to pursue the remedy;

            (3) such Holder or Holders offer to the Trustee indemnity reasonably
      satisfactory to the Trustee against any loss, liability or expense;

                                       30

<PAGE>

            (4) the Trustee does not comply with the request within 60 days
      after receipt of the request and the offer of indemnity; and

            (5) during that 60-day period, the Holders of a majority in
      principal amount of the Securities of that series do not give the Trustee
      a direction inconsistent with the request.

            A Holder may not use this Indenture to prejudice the rights of
another Holder or to obtain a preference or priority over another Holder.

SECTION 6.07 Rights of Holders to Receive Payment.

            Notwithstanding any other provision of this Indenture, the right of
any Holder of a Security to receive payment of principal of and premium, if any,
and interest on and any Additional Amounts with respect to that Security, on or
after the respective due dates expressed in that Security, or to bring suit for
the enforcement of any such payment on or after those respective dates, is
absolute and unconditional and shall not be impaired or affected without the
consent of the Holder.

SECTION 6.08 Collection Suit by Trustee.

            If an Event of Default specified in clause (1) or (2) of Section
6.01 hereof occurs and is continuing with respect to Securities of any series,
the Trustee is authorized to recover judgment in its own name and as trustee of
an express trust against the Company for the amount of principal, premium (if
any), interest and any Additional Amounts remaining unpaid on the Securities of
that series, and interest on overdue principal and premium, if any, and, to the
extent lawful, interest on overdue interest, and such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

SECTION 6.09 Trustee May File Proofs of Claim.

            The Trustee is authorized to file such proofs of claim and other
papers or documents and to take such actions, including participating as a
member, voting or otherwise, of any committee of creditors, as may be necessary
or advisable to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel) and the Holders allowed in any judicial proceeding
relative to the Company or its creditors or properties and shall be entitled and
empowered to collect, receive and distribute any money or other property payable
or deliverable on any such claims and any Bankruptcy Custodian in any such
judicial proceeding is hereby authorized by each Holder to make those payments
to the Trustee, and in the event that the Trustee shall consent to the making of
those payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 out of the estate in

                                       31
<PAGE>

any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties which the Holders of the
Securities may be entitled to receive in that proceeding whether in liquidation
or under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

SECTION 6.10 Priorities.

            If the Trustee collects any money pursuant to this Article VI, it
shall pay out the money in the following order:

            First: to the Trustee for amounts due under Section 7.07;

            Second: to Holders for amounts due and unpaid on the Securities in
respect of which or for the benefit of which that money has been collected, for
principal, premium (if any), interest and any Additional Amounts ratably,
without preference or priority of any kind, according to the amounts due and
payable on those Securities for principal, premium (if any), interest and any
Additional Amounts, respectively; and

            Third: to the Company.

            The Trustee, on prior written notice to the Company, may fix record
dates and payment dates for any payment to Holders pursuant to this Article VI.

            To the fullest extent allowed under applicable law, if for the
purpose of obtaining a judgment against the Company in any court it is necessary
to convert the sum due in respect of the principal of, premium (if any) or
interest on or Additional Amounts with respect to the Securities of any series
(the "Required Currency") into a currency in which a judgment will be rendered
(the "Judgment Currency"), the rate of exchange used shall be the rate at which
in accordance with normal banking procedures the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the New
York Business Day next preceding that on which final judgment is given. Neither
the Company nor the Trustee shall be liable for any shortfall nor shall it
benefit from any windfall in payments to Holders of Securities under this
Section 6.10 caused by a change in exchange rates between the time the amount of
a judgment against it is calculated as above and the time the Trustee converts
the Judgment Currency into the Required Currency to make payments under this
Section to Holders of Securities, but payment of that judgment shall discharge
all amounts owed by the Company on the claim or claims underlying that judgment.

SECTION 6.11 Undertaking for Costs.

            In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a trustee, a court in its

                                       32
<PAGE>

discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit
by a Holder or Holders of more than 10% in principal amount of the then
outstanding Securities of any series.

                                   ARTICLE VII
                                     TRUSTEE

SECTION 7.01 Duties of Trustee.

            (a) If an Event of Default with respect to the Securities of any
series has occurred and is continuing, the Trustee shall exercise such of the
rights and powers vested in it by this Indenture with respect to the Securities
of that series, and use the same degree of care and skill in that exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his own affairs.

            (b) Except during the continuance of an Event of Default with
respect to the Securities of any series:

            (1) the Trustee need perform only those duties that are specifically
      set forth in this Indenture and no others, and no implied covenants or
      obligations shall be read into this Indenture against the Trustee; and

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, on certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee shall examine those certificates and opinions to
      determine whether, on their face, they appear to conform to the
      requirements of this Indenture.

            (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

            (1) this paragraph does not limit the effect of Section 7.01(b);

            (2) the Trustee shall not be liable for any error of judgment made
      in good faith by a Trust Officer, unless it is proved that the Trustee was
      negligent in ascertaining the pertinent facts; and

            (3) the Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.05 hereof.

                                       33
<PAGE>

            (d) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to the
provisions of this Section 7.01.

            (e) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee may refuse to
perform any duty or exercise any right or power unless it receives indemnity
reasonably satisfactory to it against any loss, liability or expense.

            (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law. All money received by the Trustee with
respect to Securities of any series shall, until applied as herein provided, be
held in trust for the payment of the principal of, premium (if any) and interest
on and Additional Amounts with respect to the Securities of that series.

SECTION 7.02 Rights of Trustee.

            (a) The Trustee may rely on any document believed by it to be
genuine and to have been signed or presented by the proper Person. The Trustee
need not investigate any fact or matter stated in the document.

            (b) Before the Trustee acts or refrains from acting, it may require
instruction, an Officers' Certificate or an Opinion of Counsel or both to be
provided. The Trustee shall not be liable for any action it takes or omits to
take in good faith in reliance on that instruction, Officers' Certificate or
Opinion of Counsel. The Trustee may consult with counsel, and the written advice
of that counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon.

            (c) The Trustee may act through agents and shall not be responsible
for the misconduct or negligence of any agent appointed with due care.

            (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers conferred on it by this Indenture.

            (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

SECTION 7.03 May Hold Securities.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or any of
its Affiliates with the same rights it would have if it were not Trustee. Any
Agent may do the same with like rights and duties. However, the Trustee is
subject to Sections 7.10 and 7.11.

                                       34
<PAGE>

SECTION 7.04 Trustee's Disclaimer.

            The Trustee makes no representation as to the validity or adequacy
of this Indenture or the Securities; it shall not be accountable for the
Company's use of the proceeds from the Securities or any money paid to the
Company or upon the Company's direction under any provision hereof; it shall not
be responsible for the use or application of any money received by any Paying
Agent other than the Trustee; and it shall not be responsible for any statement
or recital herein or any statement in the Securities other than its certificate
of authentication.

SECTION 7.05 Notice of Defaults.

            If a Default or Event of Default with respect to the Securities of
any series occurs and is continuing and it is known to the Trustee, the Trustee
shall mail to Holders of Securities of that series a notice of the Default or
Event of Default within 90 days after it occurs. Except in the case of a Default
or Event of Default in payment of principal of, premium (if any) and interest on
and Additional Amounts or any sinking fund installment with respect to the
Securities of that series, the Trustee may withhold the notice if and so long as
a committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Holders of Securities of that series.

SECTION 7.06 Reports by Trustee to Holders.

            Within 60 days after each May 15 of each year after the execution of
this Indenture, the Trustee shall mail to Holders of a series and the Company a
brief report dated as of that reporting date that complies with TIA Section
313(a); provided, however, that if no event described in TIA Section 313(a) has
occurred within the twelve months preceding the reporting date with respect to a
series, no report need be transmitted to Holders of that series. The Trustee
also shall comply with TIA Section 313(b). The Trustee shall also transmit by
mail all reports if and as required by TIA Sections 313(c) and 313(d).

            A copy of each report at the time of its mailing to Holders of a
series of Securities shall be filed by the Company with the SEC and each
securities exchange, if any, on which the Securities of that series are listed.
The Company shall notify the Trustee if and when any series of Securities is
listed on any stock exchange.

SECTION 7.07 Compensation and Indemnity.

            The Company agrees to pay to the Trustee from time to time
compensation as agreed to by the Company and the Trustee for its acceptance of
this Indenture and services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
agrees to reimburse the Trustee on request for all reasonable disbursements,
advances and expenses incurred by it. Those expenses shall include the
reasonable compensation, disbursements and expenses of the Trustee's agents,
counsel, accountants and experts.

                                       35
<PAGE>

            The Company hereby indemnifies the Trustee against any loss,
liability or expense (including fees and expenses of counsel) incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, except as set forth in the next paragraph. The
Trustee shall notify the Company promptly of any claim for which it may seek
indemnity; provided, however, that any failure by the Trustee to so notify the
Company shall not relieve the Company of its obligations hereunder. The Company
shall defend the claim and the Trustee shall cooperate in the defense. The
Trustee may have separate counsel, and the Company shall pay the reasonable fees
and expenses of that counsel. The Company need not pay for any settlement made
without its consent.

            The Company shall not be obligated to reimburse any expense or
indemnify against any loss or liability incurred by the Trustee through
negligence or bad faith.

            To secure the payment obligations of the Company in this Section
7.07, the Trustee shall have a lien prior to the Securities on all money or
property held or collected by the Trustee, except that held in trust to pay
principal of, premium (if any) and interest on and any Additional Amounts with
respect to the Securities of any series. That lien shall survive the
satisfaction and discharge of this Indenture.

            The Company's payment obligations pursuant to this Section 7.07
shall survive the resignation and removal of the Trustee and the discharge of
this Indenture. When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(4) or (5) occurs, the expenses and
the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

SECTION 7.08 Replacement of Trustee.

            A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only on the successor Trustee's
acceptance of appointment as provided in this Section 7.08.

            The Trustee may resign and be discharged at any time with respect to
the Securities of one or more series by so notifying the Company. The Holders of
a majority in principal amount of the then outstanding Securities of any series
may remove the Trustee with respect to the Securities of that series by so
notifying the Trustee and the Company. The Company may remove the Trustee if:

            (1) the Trustee fails to comply with Section 7.10;

            (2) the Trustee is adjudged a bankrupt or an insolvent or an order
for relief is entered with respect to the Trustee under any Bankruptcy Law;

            (3) a Bankruptcy Custodian or public officer takes charge of the
Trustee or its property; or

                                       36
<PAGE>

            (4) the Trustee otherwise becomes incapable of acting.

            If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, with respect to the Securities of one or more
series, the Company shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of those series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series). Within one year after
the successor Trustee with respect to the Securities of any series takes office,
the Holders of a majority in principal amount of the Securities of that series
may appoint a successor Trustee to replace the successor Trustee appointed by
the Company.

            If a successor Trustee with respect to the Securities of any series
does not take office within 60 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company or the Holders of at least 10% in
principal amount of the then outstanding Securities of that series may petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of that series.

            If the Trustee with respect to the Securities of a series fails to
comply with Section 7.10, any Holder of Securities of that series may petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee with respect to the Securities of that
series.

            In case of the appointment of a successor Trustee with respect to
all Securities, each such successor Trustee shall deliver a written acceptance
of its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the retiring
Trustee under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, subject to the lien provided for
in Section 7.07.

            In case of the appointment of a successor Trustee with respect to
the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
(but not all) series shall execute and deliver an indenture supplemental hereto
in which each successor Trustee shall accept that appointment and that (1) shall
confer to each successor Trustee all the rights, powers and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of that successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall confirm that all the
rights, powers and duties of the retiring Trustee with respect to the Securities
of that or those series as to which the retiring Trustee is not retiring shall
continue to be vested in the retiring Trustee and (3) shall add to or change any
of the provisions of this Indenture as shall be necessary to provide for or
facilitate the administration of the trusts hereunder by more than one Trustee.
Nothing herein or in that supplemental indenture shall constitute those Trustees
co-trustees of the same trust, and each such Trustee shall be trustee of a trust
or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee. Upon the execution and delivery of that
supplemental indenture, the

                                       37
<PAGE>

resignation or removal of the retiring Trustee shall become effective to the
extent provided therein, and each such successor Trustee shall have all the
rights, powers and duties of the retiring Trustee with respect to the Securities
of that or those series to which the appointment of that successor Trustee
relates. On the request of the Company or any successor Trustee, that retiring
Trustee shall transfer to that successor Trustee all property held by that
retiring Trustee as Trustee with respect to the Securities of that or those
series to which the appointment of that successor Trustee relates.

            Notwithstanding replacement of the Trustee or Trustees pursuant to
this Section 7.08, the obligations of the Company under Section 7.07 shall
continue for the benefit of the retiring Trustee or Trustees.

SECTION 7.09 Successor Trustee by Merger, etc.

            Subject to Section 7.10, if the Trustee consolidates, merges or
converts into, or transfers all or substantially all of its corporate trust
business to, another corporation, the successor corporation without any further
act shall be the successor Trustee; provided, however, that in the case of a
transfer of all or substantially all of its corporate trust business to another
corporation, the transferee corporation expressly assumes all of the Trustee's
liabilities hereunder.

            In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to that authenticating Trustee may adopt that authentication and
deliver the Securities so authenticated; and in case at that time any of the
Securities shall not have been authenticated, any successor to the Trustee may
authenticate those Securities either in the name of any predecessor hereunder or
in the name of the successor to the Trustee; and in all those cases those
certificates shall have the full force which it is anywhere in the Securities or
in this Indenture provided that the certificate of the Trustee shall have.

SECTION 7.10 Eligibility; Disqualification.

            There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States,
any State thereof or the District of Columbia and authorized under those laws to
exercise corporate trust power, shall be subject to supervision or examination
by Federal or State (or the District of Columbia) authority and shall have, or
be a Subsidiary of a bank or bank holding company having, a combined capital and
surplus of at least $50 million as set forth in its most recent published annual
report of condition.

            The Indenture shall always have a Trustee who satisfies the
requirements of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is
subject to and shall comply with the provisions of TIA Section 310(b) during the
period of time required by this Indenture. Nothing in this Indenture shall
prevent the Trustee from filing with the SEC the application referred to in the
penultimate paragraph of TIA Section 310(b).

                                       38
<PAGE>

SECTION 7.11 Preferential Collection of Claims Against Company.

            The Trustee is subject to and shall comply with the provisions of
TIA Section 311(a), excluding any creditor relationship listed in TIA Section
311(b). A Trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated therein.

                                  ARTICLE VIII
                             DISCHARGE OF INDENTURE

SECTION 8.01 Termination of Company's Obligations.

            (a) This Indenture shall cease to be of further effect with respect
to the Securities of a series (except as to any surviving rights of conversion
or of registration of transfer or exchange of Securities expressly provided for
herein and except that the Company's obligations under Section 7.07, the
Trustee's and Paying Agent's obligations under Section 8.03 and the rights,
powers, protections and privileges accorded the Trustee under Article VII shall
survive), and the Trustee, on demand of the Company, shall execute proper
instruments acknowledging the satisfaction and discharge of this Indenture with
respect to the Securities of that series, when:

            (1)   either

                  (A) all outstanding Securities of that series theretofore
            authenticated and issued (other than destroyed, lost or stolen
            Securities that have been replaced or paid) have been delivered to
            the Trustee for cancellation; or

                  (B) all outstanding Securities of that series not theretofore
            delivered to the Trustee for cancellation:

                        (i) have become due and payable, or

                        (ii) will become due and payable at their Stated
                  Maturity within one year, or

                        (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company,

            and, in the case of clause (i), (ii) or (iii) above, the Company has
irrevocably deposited or caused to be deposited with the Trustee as funds
(immediately available to the Holders in the case of clause (i)) in trust for
that purpose (x) cash in an amount, or (y) Government Obligations, maturing as
to principal and interest at such times and in such amounts as will ensure the
availability of cash in an amount or (z) a combination thereof, which will be
sufficient, in the opinion (in the case of clauses (y) and (z)) of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the

                                       39
<PAGE>

Trustee, to pay and discharge the entire indebtedness on the Securities of that
series for principal and any interest and any Additional Amounts to the date of
that deposit (in the case of Securities which have become due and payable) or
for principal, premium, if any, interest and any Additional Amounts to the
Stated Maturity or Redemption Date, as the case may be; or

                  (C) the Company has properly fulfilled such other means of
            satisfaction and discharge as is specified, as contemplated by
            Section 2.01, to be applicable to the Securities of that series;

            (2) the Company has paid or caused to be paid all other sums payable
      by it hereunder with respect to the Securities of that series; and

            (3) the Company has delivered to the Trustee an Officers'
      Certificate stating that all conditions precedent to satisfaction and
      discharge of this Indenture with respect to the Securities of that series
      have been complied with, together with an Opinion of Counsel to the same
      effect.

            (b) Unless this Section 8.01(b) is specified as not being applicable
to Securities of a series as contemplated by Section 2.01, the Company may
terminate certain of its obligations under this Indenture ("covenant
defeasance") with respect to the Securities of a series if:

            (1) the Company has irrevocably deposited or caused to be
      irrevocably deposited with the Trustee as trust funds in trust for the
      purpose of making the following payments, specifically pledged as security
      for and dedicated solely to the benefit of the Holders of Securities of
      that series, (i) money in the currency in which payment of the Securities
      of that series is to be made in an amount, or (ii) Government Obligations
      with respect to that series, maturing as to principal and interest at such
      times and in such amounts as will ensure the availability of money in the
      currency in which payment of the Securities of that series is to be made
      in an amount or (iii) a combination thereof, that is sufficient, in the
      opinion (in the case of clauses (ii) and (iii)) of a nationally recognized
      firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay, without
      consideration of the reinvestment of any such amounts and after payment of
      all taxes or other charges or assessments in respect thereof payable by
      the Trustee, the principal of and premium (if any) and interest on and any
      Additional Amounts with respect to all Securities of that series on each
      date that such principal, premium (if any), interest or Additional Amounts
      are due and payable and (at the Stated Maturity thereof or on redemption
      as provided in Section 8.01(e)) to pay all other sums payable by it
      hereunder; provided that the Trustee shall have been irrevocably
      instructed to apply that money and/or the proceeds of those Government
      Obligations to the payment of said principal, premium (if any), interest
      and Additional Amounts with respect to the Securities of that series as
      the same shall become due;

            (2) the Company has delivered to the Trustee an Officers'
      Certificate stating that all conditions precedent to satisfaction and
      discharge of this Indenture with respect to

                                       40
<PAGE>

      the Securities of that series have been complied with, and an Opinion of
      Counsel to the same effect;

            (3) no Default or Event of Default with respect to the Securities of
      that series shall have occurred and be continuing on the date of that
      deposit;

            (4) the Company shall have delivered to the Trustee an Opinion of
      Counsel from counsel reasonably acceptable to the Trustee or a tax ruling
      to the effect that the Holders of Securities of that series will not
      recognize income, gain or loss for Federal income tax purposes as a result
      of the Company's exercise of its option under this Section 8.01(b) and
      will be subject to Federal income tax on the same amount and in the same
      manner and at the same times as would have been the case if that option
      had not been exercised;

            (5) the Company has complied with any additional conditions
      specified pursuant to Section 2.01 to be applicable to the discharge of
      Securities of that series pursuant to this Section 8.01; and

            (6) that deposit and discharge shall not cause the Trustee to have a
      conflicting interest as defined in TIA Section 310(b).

            In that event, this Indenture shall cease to be of further effect
(except as set forth in this paragraph), and the Trustee, on demand of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge under this Indenture. However, the Company's obligations in Sections
2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.02, 5.01, 7.07, 7.08 and 8.04, the
Trustee's and Paying Agent's obligations in Section 8.03 and the rights, powers,
protections and privileges accorded the Trustee under Article VII shall survive
until all Securities of that series are no longer outstanding. Thereafter, only
the Company's obligations in Section 7.07 and the Trustee's and Paying Agent's
obligations in Section 8.03 shall survive with respect to Securities of that
series.

            After making the irrevocable deposit pursuant to this Section
8.01(b) and following satisfaction of the other conditions set forth herein, the
Trustee on request shall acknowledge in writing the discharge of the Company's
obligations under this Indenture with respect to the Securities of that series,
except for those surviving obligations specified above.

            In order to have money available on a payment date to pay principal
of or premium (if any) or interest on or any Additional Amounts with respect to
the Securities, the Government Obligations shall be payable as to principal or
interest on or before that payment date in such amounts as will provide the
necessary money. Any such Government Obligations shall not be callable at the
issuer's option.

            (c) If the Company has previously complied or is concurrently
complying with Section 8.01(b) (other than any additional conditions specified
pursuant to Section 2.01 that are expressly applicable only to covenant
defeasance) with respect to Securities of a series, then, unless this Section
8.01(c) is specified as not being applicable to Securities of that series as

                                       41
<PAGE>

contemplated by Section 2.01, the Company may elect to be discharged ("legal
defeasance") from its obligations to make payments with respect to Securities of
that series, if:

            (1) no Default or Event of Default under clauses (4) and (5) of
      Section 6.01 hereof shall have occurred at any time during the period
      ending on the 91st day after the date of deposit contemplated by Section
      8.01(b) (it being understood that this condition shall not be deemed
      satisfied until the expiration of that period);

            (2) unless otherwise specified with respect to Securities of that
      series as contemplated by Section 2.01, the Company has delivered to the
      Trustee an Opinion of Counsel from counsel reasonably acceptable to the
      Trustee to the effect referred to in Section 8.01(b)(4) with respect to
      that legal defeasance, which opinion is based on (i) a private ruling of
      the Internal Revenue Service addressed to the Company, (ii) a published
      ruling of the Internal Revenue Service or (iii) a change in the applicable
      federal income tax law (including regulations) after the date of this
      Indenture;

            (3) the Company has complied with any other conditions specified
      pursuant to Section 2.01 to be applicable to the legal defeasance of
      Securities of that series pursuant to this Section 8.01(c); and

            (4) the Company has delivered to the Trustee a Company Request
      requesting legal defeasance of the Securities of that series and an
      Officers' Certificate stating that all conditions precedent with respect
      to legal defeasance of the Securities of that series have been complied
      with, together with an Opinion of Counsel to the same effect.

            In that event, the Company will be discharged from its obligations
under this Indenture and the Securities of that series to pay principal of,
premium (if any) and interest on, and any Additional Amounts with respect to,
Securities of that series, the Company's obligations under Sections 4.01, 4.02
and 5.01 shall terminate with respect to those Securities, and the entire
indebtedness of the Company evidenced by those Securities shall be deemed paid
and discharged.

            (d) If and to the extent additional or alternative means of
satisfaction, discharge or defeasance of Securities of a series are specified to
be applicable to that series as contemplated by Section 2.01, the Company may
terminate any or all of its obligations under this Indenture with respect to
Securities of a series and any or all of its obligations under the Securities of
that series if it fulfills such other means of satisfaction and discharge as may
be so specified, as contemplated by Section 2.01, to be applicable to the
Securities of that series.

            (e) If Securities of any series subject to subsections (a), (b), (c)
or (d) of this Section 8.01 are to be redeemed prior to their Stated Maturity,
whether pursuant to any optional redemption provisions or in accordance with any
mandatory or optional sinking fund provisions, the terms of the applicable trust
arrangement shall provide for that redemption, and the Company shall make such
arrangements as are reasonably satisfactory to the Trustee for the giving of
notice of redemption by the Trustee in the name, and at the expense, of the
Company.

SECTION 8.02 Application of Trust Money.

            The Trustee or a trustee reasonably satisfactory to the Trustee and
the Company shall hold in trust money or Government Obligations deposited with
it pursuant to Section 8.01 hereof. It shall apply the deposited money and the
money from Government Obligations through the Paying Agent and in accordance
with this Indenture to the payment of principal of, premium (if any) and
interest on and any Additional Amounts with respect to the Securities of the
series with respect to which the deposit was made.

SECTION 8.03 Repayment to Company.

            The Trustee and the Paying Agent shall promptly pay to the Company
at any time on the written request of the Company any excess money or Government
Obligations (or proceeds therefrom) held by them.

            Subject to the requirements of any applicable abandoned property
laws, the Trustee and the Paying Agent shall pay to the Company on written
request any money held by them for the payment of principal, premium (if any),
interest or any Additional Amounts that remain unclaimed for two years after the
date on which that payment shall have become due. After payment to the Company,
Holders entitled to the money must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another Person,
and all liability of the Trustee and the Paying Agent with respect to that money
shall cease.

SECTION 8.04 Reinstatement.

            If the Trustee or the Paying Agent is unable to apply any money or
Government Obligations deposited with respect to Securities of any series in
accordance with Section 8.01 by reason of any legal proceeding or by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting that application, the obligations of the
Company under this Indenture with respect to the Securities of that series and
under the Securities of that series shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.01 until such time as the Trustee or
the Paying Agent is permitted to apply all such money or Government Obligations
in accordance with Section 8.01; provided, however, that if the Company has made
any payment of principal of, premium (if any) or interest on or any Additional
Amounts with respect to any Securities because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
those Securities to receive such payment from the money or Government
Obligations held by the Trustee or the Paying Agent.

                     SUPPLEMENTAL INDENTURES AND AMENDMENTS

SECTION 9.01 Without Consent of Holders.

            The Company and the Trustee may amend or supplement this Indenture
or the Securities or waive any provision hereof or thereof without the consent
of any Holder:

            (1) to cure any ambiguity, omission, defect or inconsistency;

            (2) to comply with Section 5.01;

            (3) to provide for uncertificated Securities in addition to or in
      place of certificated Securities, or to provide for the issuance of bearer
      Securities (with or without coupons);

            (4) to provide any security for any series of Securities or to add
      guarantees of any series of Securities;

            (5) to comply with any requirement in order to effect or maintain
      the qualification of this Indenture under the TIA;

            (6) to add to the covenants of the Company for the benefit of the
      Holders of all or any series of Securities (and if those covenants are to
      be for the benefit of less than all series of Securities, stating that
      those covenants are expressly being included solely for the benefit of
      that series), or to surrender any right or power herein conferred on the
      Company;

            (7) to add any additional Events of Default with respect to all or
      any series of the Securities (and, if any such Event of Default is
      applicable to less than all series of Securities, specifying the series to
      which that Event of Default is applicable);

            (8) to change or eliminate any of the provisions of this Indenture;
      provided that any such change or elimination shall become effective only
      when there is no outstanding Security of any series created prior to the
      execution of that amendment or supplemental indenture that is adversely
      affected in any material respect by that change in or elimination of that
      provision;

            (9) to establish the form or terms of Securities of any series as
      permitted by Section 2.01;

            (10) to supplement any of the provisions of this Indenture to such
      extent as shall be necessary to permit or facilitate the defeasance and
      discharge of any series of Securities pursuant to Section 8.01; provided,
      however, that any such action shall not adversely affect the interest of
      the Holders of Securities of that series or any other series of Securities
      in any material respect; or

            (11) to evidence and provide for the acceptance of appointment
      hereunder by a successor Trustee with respect to the Securities of one or
      more series and to add to or change any of the provisions of this
      Indenture as shall be necessary to provide for or

                                       44
<PAGE>

      facilitate the administration of the trusts hereunder by more than one
      Trustee, pursuant to the requirements of Section 7.08.

            Upon the request of the Company, accompanied by a Board Resolution,
and upon receipt by the Trustee of the documents described in Section 9.06, the
Trustee shall, subject to Section 9.06, join with the Company in the execution
of any supplemental indenture authorized or permitted by the terms of this
Indenture and make any further appropriate agreements and stipulations that may
be therein contained.

SECTION 9.02 With Consent of Holders.

            Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture with the written consent
(including consents obtained in connection with a tender offer or exchange offer
for Securities of any one or more series or all series or a solicitation of
consents in respect of Securities of any one or more series or all series,
provided that in each case that offer or solicitation is made to all Holders of
then outstanding Securities of each such series (but the terms of that offer or
solicitation may vary from series to series)) of the Holders of at least a
majority in principal amount of the then outstanding Securities of all series
affected by that amendment or supplement (acting as one class).

            Upon the request of the Company, accompanied by a Board Resolution,
and upon the filing with the Trustee of evidence of the consent of the Holders
as aforesaid, and upon receipt by the Trustee of the documents described in
Section 9.06, the Trustee shall, subject to Section 9.06, join with the Company
in the execution of that amendment or supplemental indenture.

            It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if that consent approves the
substance thereof.

            The Holders of a majority in principal amount of the then
outstanding Securities of one or more series or of all series may waive
compliance in a particular instance by the Company with any provision of this
Indenture with respect to Securities of that series (including waivers obtained
in connection with a tender offer or exchange offer for Securities of that
series or a solicitation of consents in respect of Securities of that series,
provided that in each case that offer or solicitation is made to all Holders of
then outstanding Securities of that series (but the terms of that offer or
solicitation may vary from series to series)).

            However, without the consent of each Holder affected, an amendment,
supplement or waiver under this Section 9.02 may not:

            (1) reduce the amount of Securities whose Holders must consent to an
      amendment, supplement or waiver;

            (2) reduce the rate of or change the time for payment of interest,
      including default interest, on any Security;

                                       45
<PAGE>

            (3) reduce the principal of, premium on or any mandatory sinking
      fund payment with respect to, or change the Stated Maturity of, any
      Security or reduce the amount of the principal of an Original Issue
      Discount Security that would be due and payable on a declaration of
      acceleration of the Maturity thereof pursuant to Section 6.02;

            (4) reduce the premium, if any, payable on the redemption of any
      Security or change the time at which any Security may or shall be
      redeemed;

            (5) change any obligation of the Company to pay Additional Amounts
      with respect to any Security;

            (6) change the coin or currency or currencies (including composite
      currencies) in which any Security or any premium, interest or Additional
      Amounts with respect thereto are payable;

            (7) impair the right to institute suit for the enforcement of any
      payment of principal of, premium (if any) or interest on or any Additional
      Amounts with respect to any Security pursuant to Sections 6.07 and 6.08,
      except as limited by Section 6.06;

            (8) make any change in the percentage of principal amount of
      Securities necessary to waive compliance with certain provisions of this
      Indenture pursuant to Section 6.04 or 6.07 or make any change in this
      sentence of Section 9.02; or

            (9) waive a continuing Default or Event of Default in the payment of
      principal of, premium (if any) or interest on or Additional Amounts with
      respect to the Securities.

            A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of that series with respect to that
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

            The right of any Holder to participate in any consent required or
sought pursuant to any provision of this Indenture (and the obligation of the
Company to obtain any such consent otherwise required from that Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Securities with respect to which that consent is required or sought as of
a date identified by the Company in a notice furnished to Holders in accordance
with the terms of this Indenture.

            After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of each Security
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail that notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
amendment, supplement or waiver.

                                       46
<PAGE>

SECTION 9.03 Compliance with Trust Indenture Act.

            Every amendment or supplement to this Indenture or the Securities
shall comply in form and substance with the TIA as then in effect.

SECTION 9.04 Revocation and Effect of Consents.

            Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security, even if notation of the consent is not
made on any Security. However, any such Holder or subsequent Holder may revoke
the consent as to his or her Security or portion of a Security if the Trustee
receives written notice of revocation before the date the amendment, supplement
or waiver becomes effective. An amendment, supplement or waiver becomes
effective in accordance with its terms and thereafter binds every Holder.

            The Company may, but shall not be obligated to, fix a record date
(which need not comply with Section 316(c) of the TIA) for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver or to take any other action under this Indenture. If a record date is
fixed, then notwithstanding the provisions of the immediately preceding
paragraph, those Persons who were Holders at that record date (or their duly
designated proxies), and only those Persons, shall be entitled to consent to
that amendment, supplement or waiver or to revoke any consent previously given,
whether or not those Persons continue to be Holders after that record date. No
consent shall be valid or effective for more than 90 days after that record date
unless consents from Holders of the principal amount of Securities required
hereunder for that amendment or waiver to be effective shall have also been
given and not revoked within that 90-day period.

            After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it is of the type described in any of clauses (1)
through (9) of Section 9.02 hereof. In that case, the amendment, supplement or
waiver shall bind each Holder who has consented to it and every subsequent
Holder that evidences the same debt as the consenting Holder's Security.

SECTION 9.05 Notation on or Exchange of Securities.

            If an amendment or supplement changes the terms of an outstanding
Security, the Company may require the Holder of the Security to deliver it to
the Trustee. The Trustee may place an appropriate notation on the Security at
the request of the Company regarding the changed terms and return it to the
Holder. Alternatively, if the Company so determines, the Company in exchange for
the Security shall issue and the Trustee shall authenticate a new Security that
reflects the changed terms. Failure to make the appropriate notation or to issue
a new Security shall not affect the validity of that amendment or supplement.

            Securities of any series authenticated and delivered after the
execution of any amendment or supplement may, and shall if required by the
Company, bear a notation in form approved by the Company as to any matter
provided for in that amendment or supplement.

                                       47

SECTION 9.06 Trustee to Sign Amendments, etc.

            The Trustee shall sign any amendment or supplement authorized
pursuant to this Article if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does,
the Trustee may, but need not, sign it. In signing or refusing to sign that
amendment or supplement, the Trustee shall be entitled to receive, and, subject
to Section 7.01 hereof, shall be fully protected in relying on, an Opinion of
Counsel provided at the expense of the Company as conclusive evidence that such
amendment or supplement is authorized or permitted by this Indenture, that it is
not inconsistent herewith, and that it will be valid and binding on the Company
in accordance with its terms.

SECTION 10.01 Trust Indenture Act Controls.

            If any provision of this Indenture limits, qualifies or conflicts
with the duties imposed by operation of TIA Section 318(c), the imposed duties
shall control.

SECTION 10.02  Notices.

            Any notice or communication by the Company or the Trustee to the
other is duly given if in writing and delivered in person or mailed by
first-class mail (registered or certified, return receipt requested), telex,
