certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument

or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

     The ownership of Securities shall be proved by the Security Register.

authorized or permitted to be given or taken by Holders of Securities. If not
set by the Company prior to the first solicitation of a Holder of Securities
made by any Person in respect of any such action, or, in the case of any such
vote, prior to such vote, the record date for any such action or vote shall be
the 30th day (or, if later, the date of the most recent list of Holders required
to be provided) prior to such first solicitation or vote, as the case may be.
With regard to any record date, only the Holders of Securities on such date (or
their duly designated proxies) shall be entitled to give or take, or vote on,
the relevant action.

          every purpose hereunder if made, given, furnished or filed in writing
          to or with and received by the Trustee at its Corporate Trust Office,

     SECTION 1.06 Notice to Holders; Waiver of Notice.

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at the address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be

                                       10

made with the approval of the Trustee shall constitute a sufficient notification

apply to this Indenture as so modified or to be excluded, as the case may be.

other provision of the Indenture, or to make any other provisions with respect
to matters or questions arising under the Indenture as shall not adversely
affect the interests of the Holders in any material respect.

     The Indenture also permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on

Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of

of the Indenture shall alter or impair the obligation of the Company, which is

herein prescribed.

          other than by a Board Resolution, the manner in which any election by
          the Company to redeem the Securities shall be evidenced;

     (8)  the obligation, if any, of the Company to redeem or purchase any
          Securities of the series pursuant to any sinking fund or analogous
          provisions or at the option of the Holder thereof and the period or

          amounts shall be determined;

     (11) if other than the currency of the United States of America, the
          currency, currencies or currency units in which the principal of or
          any premium or interest on any Securities of the series shall be

                                       20
<PAGE>

          Maturity, the amount which shall be deemed to be the principal amount

          to be the principal amount shall be determined);

     (15) if applicable, that the Securities of the series, in whole or any
          specified part, shall be defeasible pursuant to Section 13.02 or
          Section 13.03 or both such Sections (or, if defeasible by another

          and any circumstances in addition to or in lieu of those set forth in
          clause (2) of the last paragraph of Section 3.05 in which any such
          Global Security may be exchanged in whole or in part for Securities
          registered, and any transfer of such Global Security in whole or in

     (17) any addition to or change in the Events of Default which applies to
          any Securities of the series and any change in the right of the

                                       21
<PAGE>

     The Securities shall be subordinated in right of payment to Senior Debt as
provided in Article XIV and/or as specified as contemplated pursuant to this
Section.

     SECTION 3.02 Denominations.

     The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as
contemplated by Section 3.01. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations of $1,000 and any integral multiple thereof.

     SECTION 3.03 Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, any Vice Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon attested by its
Treasurer or an Assistant Treasurer or its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile. The seal of the Company may be in the form of a facsimile
thereof and may be impressed, affixed, imprinted or otherwise reproduced on the
Security.

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

     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, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by one or
more Establishment Actions as permitted by Sections 2.01 and 3.01, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 6.01) shall be fully protected in
relying upon, an Opinion of Counsel stating:

     (1)  if the form of such Securities has been established by an
          Establishment Action as permitted by Section 2.01, that such form has
          been established in conformity with the provisions of this Indenture;

     (2)  if the terms of such Securities have been established by an
          Establishment Action as permitted by Section 3.01, that such terms
          have been established in conformity with the provisions of this
          Indenture; and

     (3)  that such Securities, when authenticated and delivered by the Trustee
          and issued by the Company in the manner and subject to any conditions
          specified in such Opinion of Counsel, will constitute valid and
          legally binding obligations of the Company enforceable in accordance
          with their terms, subject to bankruptcy, insolvency, fraudulent
          transfer, reorganization, moratorium and similar laws of

                                       22
<PAGE>

          general applicability relating to or affecting creditors' rights and
          to general equity principles.

     If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

     Notwithstanding the provisions of Section 3.01 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Establishment Action otherwise
required pursuant to Section 3.01 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 3.09, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

     SECTION 3.04 Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount. Until so exchanged, the temporary Securities

                                       23
<PAGE>

of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series and tenor.

     SECTION 3.05 Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept in an office or agency of the Company in
a Place of Payment a register (the register maintained in any such office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities. The Trustee, or any other party
serving in such capacity with the Trustee's consent, is hereby appointed
"Security Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided.

     Upon surrender for registration of transfer of any Security of a series at
the office or agency of the Company in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of like tenor and aggregate
principal amount.

     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

     Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.04, 9.06 or 11.07 not involving any transfer.

     If the Securities of any series (or of any series and specified tenor) are
to be redeemed in part, the Company shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption under Section 11.03 and ending at the
close of business on the day of such mailing, or (B) to register the transfer of
or exchange any

                                       24
<PAGE>

Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

     The provisions of the following clauses shall apply only to Global
Securities:

     (1)  Each Global Security authenticated under this Indenture shall be
          registered in the name of the Depositary designated for such Global
          Security or a nominee thereof and delivered to such Depositary or a
          nominee thereof or custodian therefor, and each such Global Security
          shall constitute a single Security for all purposes of this Indenture.

     (2)  Notwithstanding any other provision in this Indenture, no Global
          Security may be exchanged in whole or in part for Securities
          registered, and no transfer of a Global Security in whole or in part
          may be registered, in the name of any Person other than the Depositary
          for such Global Security or a nominee thereof unless:

          (A)  such Depositary

               (i)  has notified the Company that it is unwilling or unable to
                    continue as Depositary for such Global Security or

               (ii) has ceased to be a clearing agency registered under the
                    Exchange Act;

          (B)  there shall have occurred and be continuing an Event of Default
               with respect to such Global Security; or

          (C)  there shall exist such circumstances, if any, in addition to or
               in lieu of the foregoing as have been specified for this purpose
               as contemplated by Section 3.01.

     (3)  Subject to clause (2) above, any exchange of a Global Security for
          other Securities may be made in whole or in part, and all Securities
          issued in exchange for a Global Security or any portion thereof shall
          be registered in such names as the Depositary for such Global Security
          shall direct.

     (4)  Every Security authenticated and delivered upon registration of
          transfer of, or in exchange for or in lieu of, a Global Security or
          any portion thereof, whether pursuant to this Section, Section 3.04,
          3.06, 9.06 or 11.07 or otherwise, shall be authenticated and delivered
          in the form of, and shall be, a Global Security, unless such Security
          is registered in the name of a Person other than the Depositary for
          such Global Security or a nominee thereof.

     SECTION 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series

                                       25
<PAGE>

and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

     In case 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 such Security.

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

     SECTION 3.07 Payment of Interest; Interest Rights Preserved.

     Except as otherwise provided as contemplated by Section 3.01 with respect
to any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

     (1)  The Company may elect to make payment of any Defaulted Interest to the
          Persons in whose names the Securities of such series (or their
          respective Predecessor Securities) are registered at the close of
          business on a Special Record Date for the payment of such Defaulted
          Interest, which shall be fixed in the

                                       26
<PAGE>

          following manner. The Company shall notify the Trustee in writing of
          the amount of Defaulted Interest proposed to be paid on each Security
          of such series and the date of the proposed payment, and at the same
          time the Company shall deposit with the Trustee an amount of money
          equal to the aggregate amount proposed to be paid in respect of such
          Defaulted Interest or shall make arrangements satisfactory to the
          Trustee for such deposit prior to the date of the proposed payment,
          such money when deposited to be held in trust for the benefit of the
          Persons entitled to such Defaulted Interest as in this clause
          provided. Thereupon, the Trustee shall fix a Special Record Date for
          the payment of such Defaulted Interest which shall be not more than 15
          days and not less than 10 days prior to the date of the proposed
          payment and not less than 10 days after the receipt by the Trustee of
          the notice of the proposed payment. The Trustee shall promptly notify
          the Company of such Special Record Date and, in the name and at the
          expense of the Company, shall cause notice of the proposed payment of
          such Defaulted Interest and the Special Record Date therefor to be
          given to each Holder of Securities of such series in the manner set
          forth in Section 1.06, not less than 10 days prior to such Special
          Record Date. Notice of the proposed payment of such Defaulted Interest
          and the Special Record Date therefor having been so mailed, such
          Defaulted Interest shall be paid to the Persons in whose names the
          Securities of such series (or their respective Predecessor Securities)
          are registered at the close of business on such Special Record Date
          and shall no longer be payable pursuant to the following clause (2).

     (2)  The Company may make payment of any Defaulted Interest on the
          Securities of any series in any other lawful manner not inconsistent
          with the requirements of any securities exchange on which such
          Securities may be listed, and upon such notice as may be required by
          such exchange, if, after notice given by the Company to the Trustee of
          the proposed payment pursuant to this clause, such manner of payment
          shall be deemed practicable by the Trustee.

     If the Securities of the series are convertible or exchangeable and unless
otherwise specified as contemplated by Section 3.01, in the case of any Security
of such series which is converted or exchanged after any Regular Record Date and
on or prior to the next succeeding Interest Payment Date (other than any
Security whose Maturity is prior to such Interest Payment Date), interest whose
Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion or exchange, and such
interest (whether or not punctually paid or duly provided for) shall be paid to
the Person in whose name that Security (or one or more Predecessor Securities)
is registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Security which is converted or exchanged, interest whose Stated Maturity
is after the date of conversion or exchange of such Security shall not be
payable.

     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

                                       27

     SECTION 3.08 Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of and any premium and
(subject to Section 3.07) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

     SECTION 3.09 Cancellation.

     All Securities surrendered for payment, redemption, conversion, exchange,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and shall be promptly cancelled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. Until directed otherwise by a Company Order, all cancelled Securities
held by the Trustee shall be conspicuously marked as such and thereafter treated
in accordance with the Trustee's document retention policies; provided, however,
if any cancelled Security is destroyed by the Trustee, the Trustee shall deliver
to the Company a certificate with respect to such destruction.

     SECTION 3.10 Computation of Interest.

     Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

                                   ARTICLE IV
                           SATISFACTION AND DISCHARGE

     SECTION 4.01 Satisfaction and Discharge of Indenture.

     This Indenture shall upon Company Request cease to be of further effect
with respect to any (or all) series of Securities (except as to any surviving
rights of registration of transfer or exchange of Securities herein expressly
provided for), and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture
with respect to such Securities, when:

     (1)  either

                     from such trust, as provided in Section 10.03)

               have been delivered to the Trustee for cancellation; or

          (B)  all such Securities 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

               (iii) are to be called for redemption within one year under
                     arrangements 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,

               and the Company, in the case of (i), (ii) or (iii) above, has
               deposited or caused to be deposited with the Trustee as trust
               funds in trust for the purpose money in an amount sufficient to
               pay and discharge the entire indebtedness on such Securities not
               theretofore delivered to the Trustee for cancellation, for
               principal and any premium and interest to the date of such
               deposit (in the case of Securities which have become due and
               payable) or to the Stated Maturity or Redemption Date, as the
               case may be;

     (2)  the Company has paid or caused to be paid all other sums payable

the Trustee to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of

determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

     SECTION 5.02 Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section
5.01(5) or 5.01(6)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 5.01(5)
or 5.01(6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

     (1)  the Company has paid or deposited with the Trustee a sum sufficient to
          pay

          (A)  all overdue interest on all Securities of that series,

          (B)  the principal of (and premium, if any, on) any Securities of that
               series which have become due otherwise than by such declaration
               of acceleration and any interest thereon at the rate or rates
               prescribed therefor in such Securities,

          (C)  to the extent that payment of such interest is lawful, interest
               upon overdue interest at the rate or rates prescribed therefor in
               such Securities, and

          (D)  all sums paid or advanced by the Trustee hereunder and the
               reasonable compensation, expenses, disbursements and advances of
               the Trustee, its agents and counsel;

          and

     (2)  all Events of Default with respect to Securities of that series, other
          than the non-payment of the principal of Securities of that series
          which have become due solely by such declaration of acceleration, have
          been cured or waived as provided in Section 5.13.

     No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                                       32
<PAGE>

     SECTION 5.03 Collection of Indebtedness and Suits for Enforcement by
Trustee.

     The Company covenants that if

     (1)  default is made in the payment of any interest on any Security when
          such interest becomes due and payable and such default continues for a
          period of 30 days, or

     (2)  default is made in the payment of the principal of (or premium, if
          any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates (or
yield to maturity in the case of Original Issue Discount Securities) prescribed
therefor in such Securities, and, in addition thereto, 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, except as a result of the Trustee's negligence or bad
faith.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.

     SECTION 5.04 Trustee May File Proofs of Claim.

     In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys or
other property payable or deliverable on any such claims and to distribute the
same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due 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 6.07 except as a result of its negligence
or bad faith.

     No provision of this Indenture 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; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a

                                       33
<PAGE>

trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

     SECTION 5.05 Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel (except no such provision shall
be made respecting compensation, expenses, disbursements and advances made as a
result of Trustee's negligence), be for the ratable benefit of the Holders of
the Securities in respect of which such judgment has been recovered.

     SECTION 5.06 Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

          FIRST: To the payment of costs and expenses of collection, reasonable
     compensation to the Trustee, its agents, attorneys and counsel, and all
     other expenses and liabilities incurred, and all advances made, by the
     Trustee except as a result of its negligence or bad faith.

          SECOND: Subject to Article XIV, in case the principal of the
     outstanding Securities of any series in respect of which such moneys have
     been collected shall not have become due, to the payment of interest on the
     Securities of such series, in the order of maturity of the installments of
     such interest, with interest (to the extent that such interest has been
     collected by the Trustee) upon the overdue installments of interest at the
     same rate or the yield to maturity (in the case of Original Issue Discount
     Securities) specified on the Securities of such series, such payments to be
     made ratably to the persons entitled thereto, without discrimination or
     preference.

          THIRD: Subject to Article XIV, in case the principal of the
     outstanding Securities of any series in respect of which such moneys have
     been collected shall have become due, by declaration, or otherwise, to the
     payment of the whole amount then owing and unpaid upon the Securities of
     such series for principal, premium (if any) and interest, with interest
     upon the overdue principal, premium (if any) and (to the extent that such
     interest has been collected by the Trustee) upon overdue installments of
     interest at the same rate or the yield to maturity (in the case of Original
     Issue Discount Securities) specified on the Securities of such series; and
     in case such moneys shall be insufficient to pay in full the whole amount
     so due and unpaid upon the Securities of such series, then to the payment
     of such principal, premium (if any) and interest, without preference or

                                       34
<PAGE>

     priority of principal and premium (if any), or of any installment of
     interest over any other installment of interest, or of any Security of such
     series over any other Security of such series, ratably to the aggregate of
     such principal and accrued and unpaid interest.

     SECTION 5.07 Limitation on Suits.

     No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless:

     (1)  such Holder has previously given written notice to the Trustee of a
          continuing Event of Default with respect to the Securities of that
          series;

     (2)  The Holders of not less than 25% in principal amount of the
          Outstanding Securities of that series shall have made written request
          to the Trustee to institute proceedings in respect of such Event of
          Default in its own name as Trustee hereunder;

     (3)  such Holder or Holders have offered to the Trustee reasonable
          indemnity against the costs, expenses and liabilities to be incurred
          in compliance with such request;

     (4)  the Trustee for 60 days after its receipt of such notice, request and
          offer of indemnity has failed to institute any such proceeding; and

     (5)  no direction inconsistent with such written request has been given to
          the Trustee during such 60-day period by the Holders of a majority in
          principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

     SECTION 5.08 Unconditional Right of Holders to Receive Principal, Premium
                  and Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 3.07)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

     SECTION 5.09 Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or

                                       35
<PAGE>

has been determined adversely to the Trustee or to such Holder, then and in
every such case, subject to any determination in such proceeding, the Company,
the Trustee and the Holders shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

     SECTION 5.10 Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
3.06, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

     SECTION 5.11 Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

     SECTION 5.12 Control by Holders.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that:

     (1)  such direction shall not be in conflict with any rule of law or with
          this Indenture; and

     (2)  the Trustee may take any other action deemed proper by the Trustee
          which is not inconsistent with such direction.

     SECTION 5.13 Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default:

     (1)  in the payment of the principal of or any premium or interest on any
          Security of such series; or

                                       36
<PAGE>

     (2)  in respect of a covenant or provision hereof which under Article IX
          cannot be modified or amended without the consent of the Holder of
          each Outstanding Security of such series affected.

Upon any such waiver, such 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 5.14 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, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.

     SECTION 5.15 Waiver of Usury, Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) 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.

                                   ARTICLE VI
                                   THE TRUSTEE

     SECTION 6.01 Certain Duties and Responsibilities.

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

     SECTION 6.02 Notice of Defaults.

     If a default occurs hereunder with respect to Securities of any series, the
Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character

                                       37
<PAGE>

specified in Section 5.01(4) with respect to Securities of such series, no such
notice to Holders shall be given until at least 60 days after the occurrence
thereof. For the purpose of this Section, the term "default" means any event or
events, as the case may be, specified in Section 5.01, not including periods of
grace, if any, provided for therein.

     SECTION 6.03 Certain Rights of Trustee.

     Subject to the provisions of Section 6.01:

     (1)  the Trustee may rely and shall be protected in acting or refraining
          from acting upon any resolution, action, certificate, statement,
          instrument, opinion, report, notice, request, direction, consent,
          order, bond, debenture, note, other evidence of indebtedness or other
          paper or document believed by it to be genuine and to have been signed
          or presented by the proper party or parties;

     (2)  any request or direction of the Company mentioned herein shall be
          sufficiently evidenced by a Company Request or Company Order, and any
          resolution of the Board of Directors or Establishment Action may be
          sufficiently evidenced by a Board Resolution or Establishment Action,
          as the case may be;

     (3)  whenever in the administration of this Indenture the Trustee shall
          deem it desirable that a matter be proved or established prior to
          taking, suffering or omitting any action hereunder, the Trustee
          (unless other evidence be herein specifically prescribed) may, in the
          absence of bad faith on its part, rely upon an Officers' Certificate;

     (4)  the Trustee may consult with counsel, and the written advice of such
          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;

     (5)  the Trustee shall be under no obligation to exercise any of the rights
          or powers vested in it by this Indenture at the request or direction
          of any of the Holders pursuant to this Indenture, unless such Holders
          shall have offered to the Trustee reasonable security or indemnity
          against the costs, expenses and liabilities which might be incurred by
          it in compliance with such request or direction;

     (6)  the Trustee shall not be bound to make any investigation into the
          facts or matters stated in any resolution, action, certificate,
          statement, instrument, opinion, report, notice, request, direction,
          consent, order, bond, debenture, note, other evidence of indebtedness
          or other paper or document, but the Trustee, in its discretion, may
          make such further inquiry or investigation into such facts or matters
          as it may see fit, and, if the Trustee shall determine to make such
          further inquiry or investigation, it shall be entitled to examine the
          books, records and premises of the Company, personally or by agent or
          attorney;

     (7)  the Trustee may execute any of the trusts or powers hereunder or
          perform any duties hereunder either directly or by or through agents
          or attorneys, and the

                                       38
<PAGE>

          Trustee shall not be responsible for any misconduct or negligence on
          the part of any agent or attorney appointed with due care by it
          hereunder;

     (8)  the Trustee shall not be liable for any action taken by it in good
          faith and believed by it to be authorized or within the discretion or
          rights or powers conferred upon it by this Indenture; and

     (9)  the Trustee is not required to take notice or deemed to have notice of
          any default or Event of Default hereunder, except any Event of Default
          under Section 5.01(1), (2) or (3), unless a Responsible Officer of the
          Trustee has actual knowledge thereof or has received notice in writing
          of such default or Event of Default from the Company or the Holders of
          at least 25% in aggregate principal amount of the Outstanding
          Securities, and, in the absence of any such notice, the Trustee may
          conclusively assume that no such default or Event of Default exists.

     SECTION 6.04 Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

     SECTION 6.05 May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to 6.08 and
6.13, may otherwise deal with the Company with the same rights it would have if
it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or
such other agent.

     SECTION 6.06 Money Held in Trust.

     Money held by the Trustee, or any Paying Agent, in trust hereunder need not
be segregated from other funds except to the extent required by law. Neither the
Trustee nor any Paying Agent shall be under any liability for interest on any
money received by it hereunder except as otherwise agreed in writing with the
Company.

     SECTION 6.07 Compensation, Reimbursement and Indemnification.

     The Company agrees:

     (1)  to pay to the Trustee from time to time reasonable compensation as
          shall be agreed in writing between the Company and the Trustee for all
          services rendered by it hereunder (which compensation shall not be
          limited by any provision of law in regard to the compensation of a
          trustee of an express trust);

                                       39
<PAGE>

     (2)  except as otherwise expressly provided herein, to reimburse the
          Trustee upon its request for all reasonable expenses, disbursements
          and advances incurred or made by the Trustee in accordance with any
          provision of this Indenture (including the reasonable compensation and
          the expenses and disbursements of its agents and counsel), except any
          such expense, disbursement or advance as may be attributable to its
          negligence or bad faith; and

     (3)  to indemnify the Trustee for, and to hold it harmless against, any
          loss, liability or expense incurred without negligence or bad faith on
          its part, arising out of or in connection with the acceptance or
          administration of the trust or trusts hereunder, including the costs
          and expenses of defending itself against any claim or liability in
          connection with the exercise or performance of any of its powers or
          duties hereunder and the costs and expenses of enforcing this right to
          indemnification.

     In the event any action, suit or proceeding is brought against any Trustee
in connection with any claim for which it is entitled to indemnity hereunder, it
shall promptly (but no later than ten days following service) notify the Company
in writing, enclosing a copy of all papers served. All counsel employed to
defend any such claim shall be retained directly by the Company and may serve as
counsel to the Company and/or one or more Trustees. Absent a conflict of
interest, the Company shall not be required to pay the fees and expenses of more
than one law firm in connection with its obligations hereunder. A Trustee
entitled to indemnification may, in addition to counsel engaged by the Company,
engage counsel to represent such Trustee at its sole expense. Notwithstanding
any other provision of this Indenture, the Company shall not be liable to pay
any settlement agreed to without its written consent.

     In the event the Trustee incurs expenses or renders services in any
proceedings which result from the occurrence or continuance of an Event of
Default under Section 5.01(5) or 5.01(6) hereof, or from the occurrence of any
event which, solely by virtue of the passage of time, would become such an Event
of Default, the expenses so incurred and compensation for services so rendered
are intended to constitute expenses of administration under the United States
Bankruptcy Code or equivalent law.

     SECTION 6.08 Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series or a trustee under the indenture dated
February 26, 2002 between the Company and the Trustee respecting Senior Debt of
the Company.

     SECTION 6.09 Corporate Trustee Required; Eligibility.

     There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as

                                       40
<PAGE>

such and has a combined capital and surplus of at least $50,000,000. If any such
Person publishes reports of condition at least annually, pursuant to law or to
the requirements of its supervising or examining authority, then for the
purposes of this Section and to the extent permitted by the Trust Indenture Act,
the combined capital and surplus of such Person shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee with respect to the Securities of any
series shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

     SECTION 6.10 Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

     (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.11 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of removal, the Trustee being removed may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

     (d) If, at any time,

          (1)  the Trustee shall fail to comply with Section 6.08 after written
               request therefor by the Company or by any Holder who has been a
               bona fide Holder of a Security for at least six months, or

          (2)  the Trustee shall cease to be eligible under Section 6.09 and
               shall fail to resign after written request therefor by the
               Company or by any such Holder, or

          (3)  the Trustee shall become incapable of acting or shall be adjudged
               a bankrupt or insolvent or a receiver of the Trustee or of its
               property shall be appointed or any public officer shall take
               charge or control of the Trustee or of its property or affairs
               for the purpose of rehabilitation, conservation or liquidation,

          then, in any such case,

                                       41
<PAGE>

          (A)  the Company by a Board Resolution may remove the Trustee with
               respect to all Securities, or

          (B)  subject to Section 5.14, any Holder who has been a bona fide
               Holder of a Security for at least six months may, on behalf of
               himself and all others similarly situated, petition any court of
               competent jurisdiction for the removal of the Trustee with
               respect to all Securities and the appointment of a successor
               Trustee or Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
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
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 6.11. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.11, become the
successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.11, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 1.06. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

     SECTION 6.11 Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Trustee with respect to
all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.

                                       42
<PAGE>

     In case of the appointment hereunder 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
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (i) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (ii) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts 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 (iii) 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,
it being understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that 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; and, upon
the execution and delivery of such supplemental indenture, the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

     Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
first or second preceding paragraph, as the case may be.

     No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.

     SECTION 6.12 Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. 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 such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

                                       43
<PAGE>

     SECTION 6.13 Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

     SECTION 6.14 Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue
and upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 3.06, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent must be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

     In case at the time such successor to any Authenticating Agent with respect
to any series shall succeed to such Authenticating Agent, any of the Securities
of such series shall have been authenticated but not delivered, any such
successor to such Authenticating Agent may adopt the certificate of
authentication of any predecessor Authenticating Agent and deliver such
Securities so authenticated; and in case at that time any of the Securities of
such series shall not have been authenticated, any successor to any
Authenticating

                                       44
<PAGE>

Agent may authenticate such Securities either in the name of any predecessor
hereunder or in the name of successor Authenticating Agent; and in all such
cases such certificate shall have the full force which it is anywhere in the
Securities of such series or in this Indenture provided that the certificate of
the predecessor Authenticating Agent shall have; provided, however, that the
right to adopt the certificate of authentication of any predecessor
Authenticating Agent or to authenticate Securities in the name of any
predecessor Authenticating Agent shall apply only to its successor or successors
by merger, conversion or consolidation.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which must be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.06 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

     Any Authenticating Agent by the acceptance of its appointment shall be
deemed to have agreed with the Trustee that: it will perform and carry out the
duties of an Authenticating Agent as herein set forth; it will keep and maintain
and furnish to the Trustee from time to time as requested by the Trustee
appropriate records of all transactions carried out by it as Authenticating
Agent and will furnish the Trustee such other information and reports as the
Trustee may reasonably require; it is eligible for appointment as Authenticating
Agent under this Section 6.14 and will notify the Trustee promptly if it shall
cease to be so qualified; and it will indemnify the Trustee against any loss,
liability or expense incurred by the Trustee and will defend any claim asserted
against the Trustee by reason of acts or failures to act of the Authenticating
Agent but it shall have no liability for any action taken by it at the specific
written direction of the Trustee.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 6.07.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

     SECTION 7.01 Company to Furnish Trustee Names and Addresses of Holders.

     The Company will furnish or cause to be furnished to the Trustee:

     (1)  semi-annually, not later than June 30 and December 31 in each year, a
          list, in such form as the Trustee may reasonably require, of the names
          and addresses of the Holders of Securities of each series as of a date
          no more than 15 days prior to the date such list is furnished; and

     (2)  at such other times as the Trustee may request in writing, within 30
          days after the receipt by the Company of any such request, a list of
          similar form and content as of a date not more than 15 days prior to
          the time such list is furnished;

excluding from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.

     SECTION 7.02 Preservation of Information; Communications to Holders.

     The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.01 and the names and
addresses of Holders received by the Trustee, or its designee, in its capacity
as Security Registrar. The Trustee may destroy any list furnished to it as
provided in Section 7.01 upon receipt of a new list so furnished.

     The rights of Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding
rights and privileges of the Trustee, shall be as provided by the Trust
Indenture Act.

     Every Holder of Securities, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee nor any

              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

     SECTION 8.01 Company May Consolidate, Etc., Only on Certain Terms.

     The Company covenants that it will not merge or consolidate with any other
corporation or sell or convey all or substantially all of its assets to any
person, firm or corporation, except that the Company may merge or consolidate
with, or sell or convey all or substantially all of its assets to, any other
corporation, provided that:

     (1)  (A)  the Company shall be the continuing corporation or:

          (B)  (i)  the successor corporation (if other than the Company) shall
                    be a corporation organized and existing under the laws of
                    the United States of America or a state thereof; and

               (ii) such corporation shall expressly assume the due and punctual
                    payment of the principal of and any premium and interest on
                    all the Securities, according to their tenor, and the due
                    and punctual performance and observance of all of the
                    covenants and conditions of this Indenture to be performed
                    by the Company;

          and

     (2)  the Company or such successor corporation, as the case may be, shall
          not, immediately after such merger or consolidation, or such sale or
          conveyance, be in default in the performance of any such covenant or
          condition and no event which

                                       47
<PAGE>

          with the lapse of time, the giving of notice or both would constitute
          an Event of Default shall have occurred and be continuing.

For purposes of this Section 8.01, "substantially all of its assets" shall mean,
at any date, a portion of the non-current assets reflected in the Company's
consolidated balance sheet as of the end of the most recent quarterly period
that represents at least sixty-six and two-thirds percent (662/3%) of the total
reported value of such assets.

     SECTION 8.02 Successor Substituted.

     In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor corporation of the obligations under this Indenture
and the Securities in accordance with Section 8.01, such successor corporation
shall succeed to and be substituted for the Company, with the same effect as if
it had been named herein as a party hereto, and the Company shall thereupon be
relieved of any further obligations or liabilities hereunder and upon the
Securities and the Company as the predecessor corporation may thereupon or at
any time thereafter be dissolved, wound-up or liquidated. Such successor
corporation thereupon may cause to be signed, and may issue either in its own
name or in the name of the predecessor corporation, any or all of the Securities
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee and, upon the order of such successor corporation,
instead of the Company, and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Securities which previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication and any Securities
which such successor corporation thereafter shall cause to be signed and
delivered to the Trustee for that purpose. All the Securities so issued shall in
all respects have the same legal rank and benefit under this Indenture as the
Securities theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Securities had been issued at the date of the
execution hereof.

     In case of any such consolidation, merger, sale or conveyance, such changes
in phraseology and form (but not in substance) may be made in the Securities
thereafter to be issued as may be appropriate.

     SECTION 8.03 Trustee Entitled to Opinion.

     The Trustee, subject to the provisions of Sections 6.01 and 6.03, may
receive an Opinion of Counsel as conclusive evidence that any such
consolidation, merger, sale or conveyance, and any such assumption, complies
with the provisions of this Article.

                            SUPPLEMENTAL INDENTURES

Board of Directors, and the Trustee, at any time and from time to time, may
enter into one or more indentures supplemental hereto, in form satisfactory to
the Trustee, for one or more of the following purposes:

                                       48

          assumption by any such successor of the covenants of the Company
          herein and in the Securities; or

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

     (3)  to add any additional Events of Default for the benefit of the Holders
          of all or any series of Securities (and if such additional Events of
          Default are to be for the benefit of less than all series of
          Securities, stating that such additional Events of Default are
          expressly being included solely for the benefit of such series); or

     (4)  to add to or change any of the provisions of this Indenture to such
          extent as shall be necessary to permit or facilitate the issuance of
          Securities in bearer form, registrable or not registrable as to
          principal, and with or without interest coupons, or to permit or
          facilitate the issuance of Securities in uncertificated form; or

     (5)  to add to, change or eliminate any of the provisions of this Indenture
          in respect of one or more series of Securities, including, without
          limitation, with respect to any of the provisions set forth in Article
          XIV; provided that any such addition, change or elimination

          (A)  shall neither

               (i)  apply to any Security of any series created prior to the
                    execution of such supplemental indenture and entitled to the
                    benefit of such provision nor

               (ii) modify the rights of the Holder of any such Security with
                    respect to such provision

          or

          (B)  shall become effective only when there is no such Security
               Outstanding; or

     (6)  to secure the Securities of any series; or

     (7)  to establish the form or terms of Securities of any series as
          permitted by Sections 2.01 and 3.01; or

     (8)  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

                                       49
<PAGE>

          provide for or facilitate the administration of the trusts hereunder
          by more than one Trustee, pursuant to the requirements of Section
          6.11; or

     (9)  to make provision with respect to any conversion or exchange rights as
          contemplated by Section 3.01; or

     (10) to cure any ambiguity, to correct or supplement any provision herein
          which may be defective or inconsistent with any other provision
          herein, or to make any other provisions with respect to matters or
          questions arising under this Indenture, provided that such action
          pursuant to this clause (10) shall not adversely affect the interests
          of the Holders of Securities of any series in any material respect.

     SECTION 9.02 Supplemental Indentures With Consent of Holders.

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by its Board of Directors, and the Trustee
may enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby:

     (1)  change the Stated Maturity of the principal of, or any installment of
          principal of or interest on, any Security, or reduce the principal
          amount thereof or the rate of interest thereon or any premium payable
          upon the redemption thereof, or reduce the amount of the principal of
          an Original Issue Discount Security or any other Security which would
          be due and payable upon a declaration of acceleration of the Maturity
          thereof pursuant to Section 5.02, or change the coin or currency in
          which any Security or any premium or interest thereon is payable, or
          impair the right to institute suit for the enforcement of any such
          payment on or after the Stated Maturity thereof (or, in the case of
          redemption, on or after the Redemption Date), or adversely affect any
          right of the Holder of any Security to require the Company to
          repurchase such Security or adversely affect any right to convert or
          exchange any Security as specified as contemplated by Section 3.01, or
          modify the provisions of this Indenture with respect to the
          subordination of the Securities in a manner adverse to the Holders;

     (2)  reduce the percentage in principal amount of the Outstanding
          Securities of any series, the consent of whose Holders is required for
          any such supplemental indenture, or the consent of whose Holders is
          required for any waiver (of compliance with certain provisions of this
          Indenture or certain defaults hereunder and their consequences)
          provided for in this Indenture; or

     (3)  modify any of the provisions of this Section, Section 5.13 or Section
          10.05, except to increase any percentage set forth in such Sections or
          to provide that certain other provisions of this Indenture cannot be
          modified or waived without

                                       50
<PAGE>

          the consent of the Holder of each Outstanding Security affected
          thereby; provided, however, that this clause shall not be deemed to
          require the consent of any Holder with respect to changes in the
          references to "the Trustee" and concomitant changes in this Section
          and Section 10.05, or the deletion of this proviso, in accordance with
          the requirements of Sections 6.11 and 9.01(8).

     A supplemental indenture which 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 such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

     SECTION 9.03 Execution of Supplemental Indentures.

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.01) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

     SECTION 9.04 Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

     SECTION 9.05 Conformity With Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

     SECTION 9.06 Reference in Securities to Supplemental Indentures.

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

                                    COVENANTS

     SECTION 10.01 Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay or cause to be paid the
principal of (including any amount in respect of original issue discount) and
any premium and interest on each of the Securities of such series at the Place
of Payment, at the respective times and in the manner provided in the Securities
and this Indenture. The principal of, premium, and interest on the Securities
shall be payable only in accordance with the terms of the relevant Security.

     SECTION 10.02 Maintenance of Office or Agency.

     The Company will maintain in the Borough of Manhattan, The City of New
York, and in each other Place of Payment for any series of Securities an office
or agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of such 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, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, or an affiliate of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

     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 such purposes and may from time to time rescind such
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 the Borough of Manhattan, The City of New York, and in each other Place of
Payment for Securities of any series for such 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 10.03 Money for Securities Payments to be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of or any premium
or interest on any Securities of that series, deposit with a Paying Agent a sum
sufficient to pay such amount, such

                                       52
<PAGE>

sum to be held as provided by the Trust Indenture Act, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

     The Company will cause each Paying Agent, other than the Trustee or the
Company, for any series of Securities to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (1) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2)
during the continuance of any default by the Company (or any other obligor upon
the Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series. Each of the Company and the Trustee,
having agreed to the foregoing on its behalf as a Paying Agent by its execution
and delivery of this instrument, has hereby satisfied the provisions of this
paragraph with respect to itself as a Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in New York, New York,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the Company
free of the trust formerly impressed upon it.

     SECTION 10.04 Statement by Officers as to Default.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the knowledge of the signers thereof the
Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

<PAGE>

     SECTION 10.05 Waiver of Certain Covenants.

     Except as otherwise specified as contemplated by Section 3.01 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 3.01(18),
9.01(2) or 9.01(7) for the benefit of the Holders of such series if before the
time for such compliance the Holders of at least a majority in principal amount
of the Outstanding Securities of such series shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

     SECTION 11.01 Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 3.01 for such Securities) in accordance
with this Article.

     SECTION 11.02 Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution or in another manner specified as contemplated by Section
3.01 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

     SECTION 11.03 Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), 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 such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination or any integral multiple thereof) for such Security. If less than
all the

                                       54
<PAGE>

Securities of such series and of a specified tenor are to be redeemed (unless
such redemption affects only a single Security), 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 such series and specified tenor
not previously called for redemption in accordance with the preceding sentence.

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

     The provisions of the two preceding paragraphs shall not apply with respect
to any redemption affecting only a single Security, whether such Security is to
be redeemed in whole or in part. In the case of any such redemption in part, the
unredeemed portion of the principal amount of the Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.

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

     SECTION 11.04 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 Securities to be redeemed, at his address appearing in the
Security Register.

     All notices of redemption shall state:

     (1)  the Redemption Date,

     (2)  the Redemption Price,

     (3)  if less than all the Outstanding Securities of any series consisting
          of more than a single Security are to be redeemed, the identification
          (and, in the case of partial redemption of any such Securities, the
          principal amounts) of the particular Securities to be redeemed and, if
          less than all the Outstanding Securities of any series consisting of a
          single Security are to be redeemed, the principal amount of the
          particular Security to be redeemed,

     (4)  that on the Redemption Date the Redemption Price will become due and
          payable upon each such Security to be redeemed and, if applicable,
          that interest thereon will cease to accrue on and after said date,

     (5)  the place or places where each such Security is to be surrendered for
          payment of the Redemption Price,

     (6)  that the redemption is for a sinking fund, if such is the case, and

                                       55
<PAGE>

     (7)  if applicable, the conversion price or exchange rate, the date on
          which the right to convert or exchange the Securities to be redeemed
          shall terminate and the place or places where such Securities may be
          surrendered for conversion or exchange, as the case may be.

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 request, by the Trustee in
the name and at the expense of the Company and shall be irrevocable.

     SECTION 11.05 Deposit of Redemption Price.

     Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 10.03) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date other than any Securities called for redemption
on that date which have been converted or exchanged prior to the date of such
deposit.

     If any Security called for redemption is converted or exchanged, any money
deposited with the Trustee or with any Paying Agent or so segregated and held in
trust for the redemption of such Security shall (subject to any right of the
Holder of such Security or any Predecessor Security to receive interest as
provided in the last paragraph of Section 3.07) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.

     SECTION 11.06 Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.01, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 3.07.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

     SECTION 11.07 Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed

                                       56
<PAGE>

by, the Holder thereof or his attorney duly authorized in writing), and the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and of like tenor, of any authorized denomination as requested
by such Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                  SINKING FUNDS

     SECTION 12.01 Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.01 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment," and
any payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an "optional sinking fund payment." If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 12.02. Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

     SECTION 12.02 Satisfaction of Sinking Fund Payments with Securities.

     The Company

     (1)  may deliver Outstanding Securities of a series (other than any
          Securities previously called for redemption) and

     (2)  may apply as a credit Securities of a series which have been redeemed
          either at the election of the Company pursuant to the terms of such
          Securities or through the application of permitted optional sinking
          fund payments pursuant to the terms of such Securities,

in each case in satisfaction of all or any part of any sinking fund payment with
respect to any Securities of such series required to be made pursuant to the
terms of such Securities as and to the extent provided for by the terms of such
Securities; provided that the Securities to be so credited have not been
previously so credited. The Securities to be so credited shall be received and
credited for such purpose by the Trustee at the Redemption Price, as specified
in the Securities so to be redeemed, for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

     SECTION 12.03 Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the

                                       57
<PAGE>

portion thereof, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities pursuant to Section 12.02 and will also deliver to the Trustee any
Securities to be so delivered. Not less than 15 nor more than 45 days prior to
each such sinking fund payment date, the Trustee shall select the Securities to
be redeemed upon such sinking fund payment date in the manner specified in
Section 11.03 and cause notice of the redemption thereof to be given in the name
of and at the expense of the Company in the manner provided in Section 11.04.
Such notice having been duly given, the redemption of such Securities shall be
made upon the terms and in the manner stated in Sections 11.06 and 11.07.

                                  ARTICLE XIII

     The Company may elect, at its option at any time, to have Section 13.02 or
Section 13.03 applied to any Securities or any series of Securities, as the case
may be, designated pursuant to Section 3.01 as being defeasible pursuant to such
Section 13.02 or 13.03, in accordance with any applicable requirements provided
pursuant to Section 3.01 and upon compliance with the conditions set forth below
in this Article. Any such election shall be evidenced by a Board Resolution or
in another manner specified as contemplated by Section 3.01 for such Securities.
With respect to any series subject to conversion or exchange, the terms of any
defeasance shall be specified pursuant to Section 3.01.

     SECTION 13.02 Defeasance and Discharge.

     Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations, and the
provisions of Article XIV shall cease to be effective, with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 13.04 are satisfied (hereinafter called "Defeasance"). For this
purpose, such Defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Securities and to have
satisfied all its other obligations under such Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging the same), subject to
the following which shall survive until otherwise terminated or discharged
hereunder:

     (1)  the rights of Holders of such Securities to receive, solely from the
          trust fund described in Section 13.04 and as more fully set forth in
          such Section, payments in respect of the principal of and any premium
          and interest on such Securities when payments are due,

     (2)  the Company's obligations with respect to such Securities under
          Sections 3.04, 3.05, 3.06, 10.02 and 10.03,

                                       58
<PAGE>

     (4)  this Article.

     Subject to compliance with this Article, the Company may exercise its
option (if any) to have this Section applied to any Securities notwithstanding
the prior exercise of its option (if any) to have Section 13.03 applied to such
Securities.

     SECTION 13.03 Covenant Defeasance.

     Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be,

     (1)  the Company shall be released from its obligations under Section
          8.01(1)(B)(i) and any covenants provided pursuant to Section 3.01(18),
          9.01(2) or 9.01(7) for the benefit of the Holders of such Securities,

     (2)  the occurrence of any event specified in Sections 5.01(3), 5.01(4)
          (with respect to any of Section 8.01(1)(B)(i) and any such covenants
          provided pursuant to Section 3.01(18), 9.01(2) or 9.01(7)) and 5.01(7)
          shall be deemed not to be or result in an Event of Default, and

     (3)  the provisions of Article XIV shall cease to be effective,

in each case with respect to such Securities as provided in this Section on and
after the date the conditions set forth in Section 13.04 are satisfied
(hereinafter called "Covenant Defeasance"). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, 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 specified Section (to the extent so specified
in the case of Section 5.01(4)) or Article XIV, whether directly or indirectly
by reason of any reference elsewhere herein to any such Section or Article or by
reason of any reference in any such Section or Article to any other provision
herein or in any other document, but the remainder of this Indenture and such
Securities shall be unaffected thereby.

     SECTION 13.04 Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to the application of Section 13.02
or Section 13.03 to any Securities or any series of Securities, as the case may
be:

          with the Trustee (or another trustee which satisfies the requirements
          contemplated by Section 6.09 and agrees to comply with the provisions
          of this Article applicable to it) as trust funds in trust for the
          purpose of making the following payments, specifically pledged as
          security for, and dedicated solely to, the benefits of the Holders of
          such Securities,

          (A)  money in an amount (in such currency, currencies or currency unit
               or units in which the Securities of such series are payable), or

                                       59
<PAGE>

          (B)  in the case of Securities denominated in Dollars, U.S. Government
               Obligations, or, in the case of Securities denominated in a
               Foreign Currency, Foreign Government Obligations, which through
               the scheduled payment of principal and interest in respect
               thereof in accordance with their terms will provide, not later
               than one day before the due date of any payment, money in an
               amount, or

          (C)  a combination thereof,

          in each case sufficient, in the opinion of a nationally recognized
          firm of independent public accountants expressed in a written
          certification thereof delivered to the Trustee, to pay and discharge,
          and which shall be applied by the Trustee (or any such other
          qualifying trustee) to pay and discharge, the principal of and any
          premium and interest on such Securities on the respective Stated
          Maturities, in accordance with the terms of this Indenture and such
          Securities. As used herein, "U.S. Government Obligation" means:

          (x)  any security which is

               (i)  a direct obligation of the United States of America for the
                    payment of which the full faith and credit of the United

               (ii) an obligation of a Person controlled or supervised by and
                    acting as an agency or instrumentality of the United States

                    guaranteed as a full faith and credit obligation by the
                    United States of America,

               which, in either case (i) or (ii), is not callable or redeemable
               at the option of the issuer thereof; and

          (y)  any depositary receipt issued by a bank (as defined in Section
               3(a)(2) of the Securities Act) as custodian with respect to any
               U.S. Government Obligation which is specified in clause (x) above
               and held by such bank for the account of the holder of such
               depositary receipt, or with respect to any specific payment of
               principal of or interest on any U.S. Government Obligation which
               is so specified and held, provided that (except as required by
               law) such custodian is not authorized to make any deduction from
               the amount payable to the holder of such depositary receipt from
               any amount received by the custodian in respect of the U.S.
               Government Obligation or the specific payment of principal or
               interest evidenced by such depositary receipt.

     (2)  In the event of an election to have Section 13.02 apply to any
          Securities or any series of Securities, as the case may be, the
          Company shall have delivered to the Trustee an Opinion of Counsel
          stating that

                                       60
<PAGE>

          (A)  the Company has received from, or there has been published by,
               the Internal Revenue Service a ruling, or

          (B)  since the date of this instrument, there has been a change in the
               applicable Federal income tax law,

          in either case (A) or (B) to the effect that, and based thereon such
          opinion shall confirm that, the Holders of such Securities will not
          recognize gain or loss for Federal income tax purposes as a result of
          the deposit, Defeasance and discharge to be effected with respect to
          such Securities and will be subject to Federal income tax on the same
          amount, in the same manner and at the same times as would be the case
          if such deposit, Defeasance and discharge were not to occur.

     (3)  In the event of an election to have Section 13.03 apply to any
          Securities or any series of Securities, as the case may be, the
          Company shall have delivered to the Trustee an Opinion of Counsel to
          the effect that the Holders of such Securities will not recognize gain
          or loss for Federal income tax purposes as a result of the deposit and
          Covenant Defeasance to be effected with respect to such Securities and
          will be subject to Federal income tax on the same amount, in the same
          manner and at the same times as would be the case if such deposit and
          Covenant Defeasance were not to occur.

     (4)  No event which is, or after notice or lapse of time or both would
          become, an Event of Default with respect to such Securities or any
          other Securities shall have occurred and be continuing at the time of
          such deposit or, with regard to any such event specified in Sections
          5.01(5) and (6), at any time on or prior to the 90th day after the
          date of such deposit (it being understood that this condition shall
          not be deemed satisfied until after such 90th day).

     (5)  Such Defeasance or Covenant Defeasance shall not cause the Trustee to
          have a conflicting interest within the meaning of the Trust Indenture
          Act (assuming all Securities are in default within the meaning of such
          Act).

     (6)  Such Defeasance or Covenant Defeasance shall not result in a breach or
          violation of, or constitute a default under, any other agreement or
          instrument to which the Company is a party or by which it is bound.

     (7)  Such Defeasance or Covenant Defeasance shall not result in the trust
          arising from such deposit constituting an investment company within
          the meaning of the Investment Company Act of 1940 (and any statute
          successor thereto) unless such trust shall be registered under such
          Act or exempt from registration thereunder.

     (8)  The Company shall have delivered to the Trustee an Officer's
          Certificate and an Opinion of Counsel, each stating that all
          conditions precedent with respect to such Defeasance or Covenant
          Defeasance have been complied with.

     SECTION 13.05 Deposited Money and U.S. Government Obligations to Be Held in
Trust; Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 10.03, all
money, U.S. Government Obligations (including the proceeds thereof) and Foreign
Government Obligations (including the proceeds thereof) deposited with the
Trustee or other qualifying trustee (solely for purposes of this Section and
Section 13.06, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 13.04 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium and interest, but money so held in trust need not be segregated
from other funds except to the extent required by law. Money, U.S. Government
Obligations and Foreign Government Obligations so held in trust shall not be
subject to the provisions of Article XIV.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations and
Foreign Government Obligations deposited pursuant to Section 13.04 or the
principal and interest received in respect thereof, other than any such tax, fee
or other charge which by law is for the account of the Holders of Outstanding
Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money,
U.S. Government Obligations or Foreign Government Obligations held by it as
provided in Section 13.04 with respect to any Securities which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect the
Defeasance or Covenant Defeasance, as the case may be, with respect to such
Securities.

     SECTION 13.06 Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 13.02 or 13.03 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 13.05 with respect to such
Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Company shall be
subrogated to the rights (if any) of the Holders of such Securities to receive
such payment from the money so held in trust.

                                  ARTICLE XIV
                           SUBORDINATION OF SECURITIES

     SECTION 14.01 Securities Subordinate to Senior Debt.

     The Company covenants and agrees, and each Holder of Securities of any
series by the Holder's acceptance thereof, likewise covenants and agrees, that,
to the extent and in the manner hereinafter set forth in this Article, subject
to the provisions of Article IV and Article XIII and except as may otherwise be
specified as contemplated by Section 3.01 and set forth in the Securities of a
series, the indebtedness represented by the Securities of such series and the
payment of the principal of and any premium and interest on each and all of the
Securities of such series are hereby expressly made subordinate and junior in
right of payment to the prior payment in full of all amounts then due and
payable in respect of all Senior Debt of the Company, to the extent and in the
manner herein set forth (unless a different manner is set forth in the
Securities of such series). No provision of this Article shall prevent the
occurrence of any default or Event of Default hereunder.

     Senior Debt shall not be deemed to have been paid in full unless the
holders thereof shall have received cash, securities or other property equal to
the amount of such Senior Debt then outstanding.

     SECTION 14.02 Payment over of Proceeds Upon Dissolution, Etc.

     In the event of

     (1)  any insolvency, bankruptcy, receivership, liquidation, reorganization,
          readjustment, composition or other similar proceeding in respect of
          the Company or its property,

     (2)  any proceeding for the liquidation, dissolution or other winding up of
          the Company, whether voluntary or involuntary, or bankruptcy
          proceedings,

     (3)  any assignment by the Company for the benefit of its creditors,

     (4)  any other marshalling of the assets of the Company,

all Senior Debt shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made by the Company on
account of the Securities of any series. Any payment or distribution, whether in
cash, securities or other property (other than securities of the Company or any
other corporation provided for by a plan or reorganization or a readjustment,
the payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the
Securities of any series, to the payment of all Senior Debt at the time
outstanding and to any securities issued in respect thereof under any such plan
of reorganization or readjustment), which would otherwise (but for these
subordination provisions) be payable or deliverable in respect of the Securities
of any series shall be paid or delivered directly to the holders of Senior Debt
in accordance with the priorities then existing among such holders until all
Senior Debt shall have been paid in full. No present or future holder of any
Senior Debt shall be prejudiced in the right to enforce

                                       63
<PAGE>

subordination of the indebtedness constituting the Securities of any series by
any act of failure to act on the part of the Company.

     SECTION 14.03 No Payment When Senior Debt in Default.

     In the event that

     (1)  the Company shall default in the payment of any principal of or
          premium, if any, or interest on any Senior Debt when the same becomes
          due and payable, whether at maturity or at a date fixed for prepayment
          or declaration or otherwise, or

     (2)  an event of default occurs with respect to any Senior Debt permitting
          the holders thereof to accelerate the maturity thereof and written
          notice describing such event of default and requesting commencement of
          payment blockage on transactions as thereinafter described is given to
          the Company by the holders of Senior Debt,

then, unless and until such default in payment and event of default shall have
been cured or waived or shall have ceased to exist, no direct or indirect
payment (in cash, property, securities, by set-off or otherwise) shall be made
or agreed to be made on account of the Securities of any series or any interest
thereon in respect of any repayment, redemption, retirement, purchase or other
acquisition of the Securities of any series.

     SECTION 14.04 Payment Permitted in Certain Situations.

     Nothing contained in this Article or elsewhere in this Indenture or in any
of the Securities of any series shall prevent

     (1)  the Company, at any time except during the pendency of any
          dissolution, winding-up, liquidation or reorganization of the Company,
          whether voluntary or involuntary or any bankruptcy, insolvency,
          receivership or other proceedings of the Company referred to in
          Section 14.02 or under the conditions described in Section 14.03, from
          making payments at any time of principal of or premium, if any, or
          interest on the Securities of such series, or

     (2)  the application by the Trustee of any money deposited with it
          hereunder to the payment of or on account of the principal of or
          premium, if any, or interest on the Securities of such series or the
          retention of such payment by the Holders, if, at the time of such
          application by the Trustee, it did not have knowledge that such
          payment would have been prohibited by the provisions of this Article.

     SECTION 14.05 Subrogation to Rights of Holders of Senior Debt.

     Upon the payment in full of all Senior Debt, the rights of the holders of
Securities of any series shall be subrogated to all the rights of any holders of
Senior Debt to receive any further payments or distributions applicable to the
Senior Debt until the Securities of any series shall have been paid in full, and
such payments or distributions received by the Holders of Securities of any
series by reason of such subrogation, of cash, securities or other property
which otherwise would be paid or distributed to the holders of Senior Debt,
shall, as between the Company and its

                                       64
<PAGE>

creditors other than the holders of Senior Debt, on the one hand, and the
Holders of Securities of any series, on the other, be deemed to be a payment by
the Company on account of Senior Debt, and not on account of the Securities of
any series.

     SECTION 14.06 Provisions Solely to Define Relative Rights.

     The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of Securities of any series on
the one hand and the holders of Senior Debt on the other hand. Nothing contained
in this Article or elsewhere in the Indenture or in the Securities of such
series is intended to or shall

     (1)  impair, as among the Company, its creditors other than holders of
          Senior Debt and the Holders of Securities of such series, the
          obligation of the Company, which is absolute and unconditional (and
          which, subject to the rights under this Article of the holders of
          Senior Debt, is intended to rank equally with all other general
          obligations of the Company), to pay to the Holders of Securities of
          such series the principal of (and premium, if any) and interest on the
          Securities of such series as and when the same shall become due and
          payable in accordance with their terms; or

     (2)  affect the relative rights against the Company of the Holders of
          Securities of such series and creditors of the Company, as the case
          may be, other than the holders of Senior Debt; or

     (3)  prevent the Trustee or the Holder of any Securities of such series
          from exercising all remedies otherwise permitted by applicable law
          upon default under this Indenture, subject to the rights, if any,
          under this Article of the holders of Senior Debt to receive cash,
          property and securities otherwise payable or deliverable to the
          Trustee or such Holder.

     SECTION 14.07 Trustee to Effectuate Subordination.

     Each Holder of Securities of any series by such Holder's acceptance thereof
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this Article and appoints the Trustee his attorney-in-fact for any and all such
purposes.

     SECTION 14.08 No Waiver of Subordination Provisions.

     No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof any such holder may have or be otherwise
charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the

                                       65
<PAGE>

Trustee or the Holders of the Securities of any series, without incurring
responsibility to the Holders of the Securities of such series and without
impairing or releasing the subordination provided in this Article or the
obligations hereunder of the Holders of Securities of such series to the holders
of Senior Debt, do any one or more of the following:

     (1)  change the manner, place or terms of payment or extend the time of
          payment of, or renew or alter, Senior Debt, or otherwise amend or
          supplement in any manner Senior Debt or any instrument evidencing the
          same or any agreement under which Senior Debt is outstanding;

     (2)  sell, exchange, release or otherwise deal with any property pledged,
          mortgaged or otherwise securing Senior Debt;

     (3)  release any Person liable in any manner for the collection of Senior
          Debt; and

     (4)  exercise or refrain from exercising any rights against the Company and
          any other Person.

     SECTION 14.09 Notice to Trustee.

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities of any series pursuant to the provisions of
this Article. Notwithstanding the provisions of this Article or any other
provision of the Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or
by the Trustee in respect of any Securities of any series pursuant to the
provisions of this Article, unless and until the Trustee shall have received
written notice thereof from the Company or a holder or holders of Senior Debt or
from any trustee therefor; and, prior to the receipt of any such written notice,
the Trustee, subject to the provisions of Section 6.03, shall be entitled in all
respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the notice provided for in this Section at least
two Business Days prior to the date upon which by the terms hereof any money may
become payable for any purpose (including, without limitation, the payment of
the principal of (or premium, if any) or interest on any Securities of any
series), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such moneys and to apply
the same to the purpose for which they were received and shall not be affected
by any notice to the contrary that may be received by it within two Business
Days prior to such date.

     Subject to the provisions of Section 6.03, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
to be a holder of Senior Debt (or a trustee therefor) to establish that such
notice has been given by a holder of Senior Debt (or a trustee therefor). In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of Senior Debt held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article, and
if

                                       66
<PAGE>

such evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

     SECTION 14.10 Reliance on Judicial Order or Certificate of Liquidating
Agent.

     Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 6.03, and the
Holders of Securities of any series shall be entitled to conclusively rely upon
any order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of Securities of such
series, for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the holders of the Senior Debt and other
indebtedness of the Company, as the case may be, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article.

     SECTION 14.11 Trustee Not Fiduciary for Holders of Senior Debt.

     With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article, and no implied covenants or obligations
with respect to the holders of such Senior Debt shall be read into this
Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt with respect to its obligations and
duties created hereunder and shall not be liable to any such holders or
creditors if it shall in good faith pay over or distribute to Holders of
Securities of any series or to the Company or to any other Person cash, property
or securities to which any holders of Senior Debt shall be entitled by virtue of
this Article or otherwise.

     SECTION 14.12 Rights of Trustee as Holder of Senior Debt; Preservation of
Trustee's Rights.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Debt which may at any time
be held by it, to the same extent as any other holder of Senior Debt, and
nothing in the Indenture shall deprive the Trustee of any of its rights as such
holder.

     Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.07.

     SECTION 14.13 Article Applicable to Paying Agents.

     In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; provided, however, that this

                                       67
<PAGE>

Section shall not apply to the Company or any Affiliate of the Company if it or
such Affiliate acts as Paying Agent.

     SECTION 14.14 Certain Conversions or Exchanges Deemed Payment.

     For the purposes of this Article only, (i) the issuance and delivery of
securities which are subordinate in right of payment to all then outstanding
Senior Debt to substantially the same extent as the Securities are so
subordinate ("Junior Securities") (or cash paid in lieu of fractional shares)
upon conversion or exchange of Securities of any series as contemplated by
Section 3.01, shall not be deemed to constitute a payment or distribution on
account of the principal of or premium, if any, or interest on Securities of
such series or on account of the purchase or other acquisition of Securities of
such series and (ii) the payment, issuance or delivery of cash, property or
securities (other than Junior Securities and cash paid in lieu of fractional
shares) upon conversion or exchange of Securities of any series shall be deemed
to constitute payment on account of the principal of such Securities of such
series. Nothing contained in this Article or elsewhere in the Indenture or in
the Securities of any series is intended to or shall impair, as among the
Company, its creditors other than holders of Senior Debt and the Holders of
Securities of such series the right, which is absolute and unconditional, of the
Holder of any Securities of such series to convert or exchange such Securities
of such series in accordance with the terms specified as contemplated by Section
3.01.

     SECTION 14.15 Defeasance of This Article XIV.

     The subordination of the Securities provided by this Article XIV is
expressly made subject to the provisions for defeasance or covenant defeasance
in Article XIII hereof and, anything herein to the contrary notwithstanding,
upon the effectiveness of any such defeasance or covenant defeasance, the
Securities then outstanding shall thereupon cease to be subordinated pursuant to
this Article XIV.

release (or any successor release) is not published during the week preceding
the calculation date or does not contain such yields, the rate per annum equal
to the semiannual equivalent yield to maturity of the Comparable Treasury Issue,

such redemption date. The Treasury Rate shall be calculated on the third
Business Day preceding the redemption date.

redemption from the outstanding Notes not previously called by such method as
the Trustee deems fair and appropriate.

                  9. The Notes are not subject to any sinking fund or analogous
provisions. The Notes will not be redeemable at the option of the Holder thereof
prior to Maturity.

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of February 26, 2002, (herein called the
"Indenture," which term shall have the meaning assigned to it in such
instrument), between the Company and JPMorgan Chase Bank, as Trustee (herein
called the "Trustee," which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series designated on the face hereof, limited in
aggregate principal amount to $[ ].

                  The Securities of this series are subject to redemption prior
to the Stated Maturity upon not less than 30 days' notice by mail, at any time,
in whole or in part, at the election of the Company, at a redemption price equal
to the greater of (1) 100% of the principal amount of such Securities to be
redeemed or (2) the sum of the present values of the remaining scheduled
payments of principal and interest on the Securities to be redeemed (exclusive
of interest accrued to the date of redemption) discounted to the date of
redemption on a semiannual basis (assuming a 360-day year consisting of twelve
30-day months) at the then current Treasury Rate plus [ ] basis points, plus, in
either case, accrued and unpaid interest on the principal amount being redeemed
to the date of redemption.

                  "Business Day" means any calendar day that is not a Saturday,
Sunday or legal holiday in New York, New York or Houston, Texas and on which
commercial banks are open for business in New York, New York and Houston, Texas.

                  "Comparable Treasury Issue" means the United States Treasury
security selected by an Independent Investment Banker as having a maturity
comparable to the remaining term ("Remaining Life") of the Securities 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 such Securities.

                  "Comparable Treasury Price" means, with respect to any
redemption date, (1) the average of the Reference Treasury Dealer Quotations for
such redemption date, after excluding the highest and lowest Reference Treasury
Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference
Treasury Dealer Quotations, the average of all such quotations.

<PAGE>

                  "Independent Investment Banker" means one of the Reference
Treasury Dealers that the Company appoints to act as the Independent Investment
Banker from time to time.

                  "Reference Treasury Dealer" means (1) each of Salomon Smith
Barney Inc., Banc of America Securities LLC and J.P. Morgan Securities Inc., and
their respective successors, and one other firm that is a primary U.S.
Government securities dealer (a "Primary Treasury Dealer") which we specify from
time to time; provided, however, that if any of them ceases to be a Primary
Treasury Dealer, the Company shall substitute therefor another Primary Treasury
Dealer.

                  "Reference Treasury Dealer Quotations" means, with respect to
each 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.

                  "Treasury Rate" means, with respect to any redemption date,
the rate per annum equal to: (1) the yield, under the heading which represents
the average for the immediately preceding week, appearing in the most recently
published statistical release designated "H.15(519)" or any successor
publication which is published weekly by the Board of Governors of the Federal
Reserve System and which establishes yields on actively traded United States
Treasury securities adjusted to constant maturity under the caption "Treasury
Constant Maturities," for the maturity corresponding to the Comparable Treasury
Issue; provided that, if no maturity is within three months before or after the
Remaining Life of the Securities to be redeemed, yields for the two published
maturities most closely corresponding to the Comparable Treasury Issue shall be
determined and the Treasury Rate shall be interpolated or extrapolated from such
yields on a straight line basis, rounding to the nearest month; or (2) if such
release (or any successor release) is not published during the week preceding
the calculation date or does not contain such yields, the rate per annum equal
to the semiannual 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. The Treasury Rate shall be calculated on the third
Business Day preceding the redemption date.

                  Notice of the redemption will be mailed to holders of
Securities by first-class mail at least 30 and not more than 60 days prior to
the date fixed for redemption. If fewer than all of the Securities are to be
redeemed, the Trustee will select, not more than 60 days prior to the redemption
date, the particular Securities or portions thereof for redemption from the
outstanding Securities not previously called by such method as the Trustee deems
fair and appropriate.

                                       2
<PAGE>

         Unless the Company defaults in payment of the redemption price, on or
after the redemption date, interest will cease to accrue on the Securities or
portions thereof called for redemption.

         In the event of redemption of this Security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security or of certain restrictive covenants and
Events of Default with respect to this Security, in each case upon compliance
with certain conditions set forth in the Indenture.

         If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided for in the
Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee to modify the Indenture or any supplemental indenture without the
consent of the Holders for one or more of the following purposes: (1) to
evidence the succession of another corporation to the Company; (2) to add to the
covenants of the Company; (3) to add additional events of default for the
benefit of Holders of all or any series of Securities; (4) to add to or change
provisions of the Indenture to allow the issuance of Securities in other forms;
(5) to add to, change or eliminate any of the provisions of the Indenture in
respect of one or more series of Securities thereunder, under certain conditions
specified therein; (6) to secure the Securities pursuant to the requirements of
Section 10.05 of the Indenture or otherwise; (7) to establish the form or terms
of Securities of any series as permitted by Sections 2.01 and 3.01 of the
Indenture; (8) to evidence the appointment of a successor Trustee; and (9) to
cure any ambiguity, to correct or supplement any provision of the Indenture
which may be defective or inconsistent with any other provision of the
Indenture, or to make any other provisions with respect to matters or questions
arising under the Indenture as shall not adversely affect the interests of the
Holders in any material respect.

         The Indenture also permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of not less than a majority in
principal amount of the Securities at the time Outstanding of each series to be
affected. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such series,
to waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer

<PAGE>
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

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

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

         The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

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

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this

Security be overdue, and neither the Company, the Trustee nor any such agent
shall be affected by notice to the contrary.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.
