conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with and an Opinion of Counsel stating that
in the opinion of such counsel all such conditions precedent, if any, have been
complied with and, unless otherwise provided herein, no additional certificate
or opinion need be furnished.

     Every certificate or opinion, other than the Officers' Certificate called
for by Section 10.07, with respect to compliance with a condition or covenant
provided for in this Indenture shall include

     (a) a statement that each individual signing such certificate or opinion

reasonable care should know, that the certificate or opinion or representations

it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company

     SECTION 1.04. Acts of Holders

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Holders in person or by an agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee and, where it is hereby expressly required, to the Company. If any
Securities are denominated in coin or currency other than that of the United
States, then for the purposes of determining whether the Holders of the
requisite principal amount of Securities have taken any action with respect to
the Securities of more than one series as herein described, the principal
amount of such Securities shall be deemed to be that amount of United States
dollars that could be obtained for such principal amount on the basis of the
spot rate of exchange into United States dollars for the currency in which such
Securities are denominated (as evidenced to the Trustee by an Officers'
Certificate) as of the date the taking of such action by the Holders of such
requisite principal amount is evidenced to the Trustee as provided in the
immediately preceding sentence. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 6.01)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

     (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person

                                       11
<PAGE>

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

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

     (d) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of
the same Security and the Holder of every Security issued upon the registration
of transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

     SECTION 1.05. Notices, Etc., to Trustee and Company

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

     (a) the Trustee by any Holder or by the Company shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing to or
with the Trustee at its Corporate Trust Office, Attention: Corporate Trust
Administration, or at any other address previously furnished in writing to the
Company and the Holders by the Trustee; or

     (b) the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to it
at 21001 Van Born Road, Taylor, Michigan 48180 or at any other address
previously furnished in writing to the Trustee by the Company.

     SECTION 1.06. Notice to Holders; Waiver

     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 his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, 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

                                       12
<PAGE>

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 made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

     SECTION 1.07. Conflict with Trust Indenture Act

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

     SECTION 1.08. Effect of Headings and Table of Contents

     The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

     SECTION 1.09. Successors and Assigns

     All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.

     SECTION 1.10. Separability Clause

     In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

     SECTION 1.11. Benefits of Indenture

     Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the Parties hereto, any Authenticating Agent,
any Paying Agent, any Securities Registrar and their successors hereunder and
the Holders, any benefit or any legal or equitable right, remedy or claim under
this Indenture.

     SECTION 1.12. Governing Law

     This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York without regard to any
conflicts of laws principles therein.

     SECTION 1.13. Legal Holidays

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then, unless otherwise specified in such Security, payment of interest or
principal (and premium, if any) need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date
or Redemption Date, or at the Stated Maturity, provided that no interest shall
accrue for the period from and after such Interest Payment Date, Redemption
Date or Stated Maturity, as the case may be.

     SECTION 1.14. Counterparts

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                                   ARTICLE 2
                                 SECURITY FORMS

     SECTION 2.01. Forms Generally

     The Securities of each series shall be in substantially the form set forth
in Exhibit A, or in such other form as shall be established by or pursuant to a
Board Resolution or in one or more indentures supplemental hereto, in each case
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by this Indenture, and may have such letters,
numbers or other marks of identification and such legends or endorsements
placed thereon as may be required to comply with any law or any rules or
regulations pursuant thereto, or with the rules of any securities exchange or
to conform to general usage, all as may consistently herewith be determined by
the officers executing such Securities, as evidenced by their execution of the
Securities. If the form of Securities of any series is established by action
taken pursuant to a Board Resolution, a copy of an appropriate record of such
action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the Company
Order contemplated by Section 3.03 for the authentication and delivery of such
Securities.

                                       14
<PAGE>

     The definitive Securities shall be printed, lithographed or engraved on
steel engraved borders or may be produced in any other manner, all as
determined by the officers executing such Securities, as evidenced by their
execution of such Securities.

     SECTION 2.02. Securities in Permanent Global Form

     If the Company shall establish pursuant to Section 3.01 that the
Securities of a series are to be issued in whole or in part in permanent global
form, then notwithstanding Section 3.01(g) and the provisions of Section 3.02,
any such Security shall represent such of the Outstanding Securities of such
series as shall be specified therein and may provide that it shall represent
the aggregate amount of Outstanding Securities from time to time endorsed
thereon and that the aggregate amount of Outstanding Securities represented
thereby may from time to time be reduced or increased to reflect exchanges. Any
endorsement of a Security in permanent global form to reflect the amount, or
any increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made by the Trustee or the Security Registrar in such manner
and upon instructions given by such Person or Persons as shall be specified in
such Security in permanent global form or in the Company Order to be delivered
to the Trustee pursuant to Section 3.03 or Section 3.04. Subject to the
provisions of Section 3.03 and, if applicable, Section 3.04, the Trustee or the
Security Registrar shall deliver and redeliver any Security in permanent global
form in the manner and upon instructions given by the Person or Persons
specified in such Security or in the applicable Company Order. If a Company
Order pursuant to Section 3.03 or 3.04 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a global Security shall be in writing but need not
comply with Section 1.02 and need not be accompanied by an Officers'
Certificate or an Opinion of Counsel, provided that the form of permanent
global Security to be endorsed, delivered or redelivered has previously been
covered by an Opinion of Counsel.

     The provisions of the last sentence of Section 3.03 shall only apply to
any Security represented by a Security in permanent global form if such
Security was never issued and sold by the Company and the Company delivers to
the Trustee or the Security Registrar the Security in permanent global form
together with written instructions (which need not comply with Section 1.02 and
need not be accompanied by an Officers' Certificate or an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 3.03.

     Unless otherwise specified as contemplated by Section 3.01 for the
Securities evidenced thereby, every Security in permanent global form
authenticated and delivered hereunder shall bear a legend in substantially the
following form:

                                       15
<PAGE>

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITARY TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER,
EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF
THE DEPOSITARY OR ITS NOMINEE AND ANY PAYMENT IS MADE TO THE DEPOSITARY OR ITS
NOMINEE, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR
TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF HAS AN INTEREST
HEREIN.

series is payable;

specified part, shall be defeasible pursuant to Section 4.02 or Section 10.06
(and in the case of defeasance pursuant to Section 10.06, the negative or
restrictive covenants that shall be subject to such defeasance) or both
Sections and if other than by a Board Resolution, the manner in which any
election by the Company to defease those securities shall be evidenced;

payment of the principal of, and any premium and interest on, the Securities of
the series shall be payable if other than the currency of the United States of
America;

     (m) if the principal of, or any premium or interest on, any Securities of
the series is to be payable, at the election of the Company or the Holder

made and the amount so payable (or the manner in which such amount shall be
determined);

     (n) if the amount of payments of principal of, or any premium or interest
on, the Securities of the series may be determined with reference to an index
or pursuant to a formula, the manner in which such amounts shall be determined;

     (o) if the principal amount payable at the Stated Maturity of any
Securities of the series will not be determinable as of any one or more dates
prior to the Stated Maturity, the amount which shall be deemed to be the
principal amount of such Securities as of any such date for any purpose
thereunder or hereunder, including the principal amount thereof which shall be
due and payable upon any Maturity other than the Stated Maturity or which shall
be deemed to be Outstanding as of any date prior to the Stated Maturity (or, in
any such case, the manner in which such amount deemed to be the principal
amount shall be determined);

     (q) whether and under what circumstances the Company will pay additional
amounts on the Securities of the series held by a person who is not a U.S.

Securities rather than pay such additional amounts;

     (r) any trustees, depositaries, authenticating or paying agents, transfer

series;

                                       18

terms relating to the adjustment thereof and the period during which such
Securities may be so converted or exchanged;

     (t) any addition to or change in the covenants set forth in Article 10
which applies to any Securities of the series; and

     (u) any other terms of the series (which terms shall not be inconsistent
with the provisions of this Indenture, except as permitted by Section 9.01(e)).

     All Securities of any one series shall be substantially identical except
as to denomination and except as may otherwise be provided in or pursuant to
the Board Resolution referred to above and (subject to Section 3.03) set forth
in the Officers' Certificate that established the form of the Securities of
such series or in any such indenture supplemental hereto.

     All Securities of any one series need not be issued at the same time and
may be issued from time to time, consistent with the terms of this Indenture,
if so provided in or pursuant to such Board Resolution, such Officers'
Certificate or in any such indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

     SECTION 3.02. Denominations

     The Securities of each series shall be issuable in registered form without
coupons and, except for any Security issuable in permanent global form, in such
denominations as shall be specified in accordance with Section 3.01. In the
absence of such provisions with respect to the Securities of any series, the
Securities of such series, other than a Security issuable in permanent global
form, shall be issuable in denominations of $1,000 and any 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, its President, one of its Vice Presidents or its Treasurer,
attested by its

                                       19
<PAGE>

Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

     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 the applicable
documents referred to below in this Section, and the Trustee shall thereupon
authenticate and deliver such Securities to or upon the order of the Company
(contained in the Company Order referred to below in this Section) or pursuant
to such procedures acceptable to the Trustee and to such recipients as may be
specified from time to time by a Company Order. The maturity date, original
issue date, interest rate and any other terms of the Securities of such series
shall be determined by or pursuant to such Company Order and procedures. If
provided for in such procedures, such Company Order may authorize
authentication and delivery pursuant to oral instructions from the Company or
its duly authorized agent, which instructions shall be promptly confirmed in
writing. In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive (in the case of subparagraphs 3.03(ii),
3.03(iii) and 3.03(iv) below, only at or before the time of the first request
of the Company to the Trustee to authenticate Securities of such series) and
(subject to Section 6.01) shall be fully protected in relying upon, unless and
until such documents have been superseded or revoked:

          (i) a Company Order requesting such authentication and setting forth
     delivery instructions if the Securities are not to be delivered to the
     Company, provided that, with respect to Securities of a series subject to
     a Periodic Offering, (a) such Company Order may be delivered by the
     Company to the Trustee prior to the delivery to the Trustee of such
     Securities for authentication and delivery, (b) the Trustee shall
     authenticate and deliver Securities of such series for original issue from
     time to time, in an aggregate principal amount not exceeding the aggregate
     principal amount, if any, established for such series, pursuant to a
     Company Order or pursuant to procedures acceptable to the Trustee as may
     be specified from time to time by a Company Order, (c) the maturity date
     or dates, original issue date or dates, interest rate or rates and any
     other terms of Securities of such series shall be determined by a Company
     Order or pursuant to such procedures and (d) if provided for in such
     procedures, such Company Order may authorize

                                       20
<PAGE>

     authentication and delivery pursuant to oral or electronic instructions
     from the Company or its duly authorized agent or agents, which oral
     instructions shall be promptly confirmed in writing;

          (ii) any Board Resolution, Officers' Certificate and/or executed
     supplemental indenture referred to in Sections 2.01 and 3.01 by or
     pursuant to which the forms and terms of the Securities were established;

          (iii) an Officers' Certificate setting forth the form or forms and
     (to the extent established) the terms of the Securities, stating that the
     form or forms and any such terms of the Securities have been established
     pursuant to Sections 2.01 and 3.01 and comply with this Indenture, and
     covering such other matters as the Trustee may reasonably request; and

          (iv) At the option of the Company, either an Opinion of Counsel, or a
     letter addressed to the Trustee permitting to it rely on an Opinion of
     Counsel, substantially to the effect that:

               (A) the forms of the Securities have been duly authorized and
          established in conformity with the provisions of this Indenture;

               (B) if all of the terms of the Securities of such series have
          been established, the terms of the Securities have been duly
          authorized by the Company and established in conformity with the
          provisions of this Indenture, and, in the case of all other
          offerings, certain terms of the Securities have been established
          pursuant to a Board Resolution, an Officers' Certificate or a
          supplemental indenture in accordance with this Indenture, and when
          such other terms as are to be established pursuant to procedures set
          forth in a Company Order shall have been established, all such terms
          will have been duly authorized by the Company and will have been
          established in conformity with the provisions of this Indenture;

               (C) when the Securities have been executed by the Company and
          authenticated by the Trustee in accordance with the provisions of
          this Indenture and delivered to and duly paid for by the purchasers
          thereof, they will have been duly issued under this Indenture and
          will be valid and legally binding obligations of the Company,
          enforceable in accordance with their respective terms, and will be
          entitled to the benefits of this Indenture; and

               (D) the execution and delivery by the Company of, and the
          performance by the Company of its obligations under, the Securities

                                       21
<PAGE>

          will not contravene any provision of applicable law or the
          certificate of incorporation or by-laws of the Company or, to the
          best of such counsel's knowledge, any agreement or other instrument
          binding upon the Company or any of its subsidiaries that is material
          to the Company and its subsidiaries, considered as one enterprise,
          or, to the best of such counsel's knowledge, any judgment, order or
          decree of any governmental body, agency or court having jurisdiction
          over the Company or any subsidiary, and no consent, approval or
          authorization of any governmental body or agency is required for the
          performance by the Company of its obligations under the Securities,
          except such as are specified and have been obtained and such as may
          be required by the securities or blue sky laws of the various states
          in connection with the offer and sale of the Securities.

     In rendering such opinions, such counsel may qualify any opinions as to
enforceability by stating that such enforceability may be limited by
bankruptcy, insolvency, reorganization, liquidation, moratorium and other
similar laws affecting the rights and remedies of creditors and is subject to
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law). Such counsel may rely upon
opinions of other counsel (copies of which shall be delivered to the Trustee),
who shall be counsel reasonably satisfactory to the Trustee, in which case the
opinion shall state that such counsel believes he and the Trustee are entitled
so to rely. Such counsel may also state that, insofar as such opinion involves
factual matters, he has relied, to the extent he deems proper, upon
certificates of officers of the Company and its subsidiaries and certificates
of public officials.

     The Trustee shall have the right to decline to authenticate and deliver
any Securities under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Company or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible
Officers shall determine that such action would expose the Trustee to personal
liability to existing Holders or would affect the Trustee's own rights, duties
or immunities under the Securities, this Indenture or otherwise.

     Each Security shall be dated the date of its authentication. Unless
otherwise specified as contemplated by Section 3.01 for any Security, interest
on the each Security will accrue from 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

                                       22
<PAGE>

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 and is entitled to the benefits of this Indenture.

     Notwithstanding the foregoing and subject, in the case of a Security in
permanent global form, to Section 2.02, 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 together with a written statement (which need not
comply with Section 1.02 and need not be accompanied by an Opinion of Counsel)
directing such cancellation and stating that such Security has never been
issued and sold by the Company, 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 a like principal amount of
definitive Securities of the same series and of like tenor of authorized
denominations. Until so exchanged the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

     SECTION 3.05. Registration, Registration of Transfer and Exchange

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively

                                       23
<PAGE>

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 transfers of Securities. The Trustee 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 any series
at the office or agency 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 a like aggregate principal amount
and of like tenor.

     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 a
like aggregate principal amount and of like tenor, 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.

     The Company shall not be required (i) to issue, register the transfer of
or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.03 and
ending at the close of business on the day of such mailing, or (ii) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

                                       24

     The provisions of Clauses (a) - (g) below shall apply only to permanent
global Securities:

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

     (b) Notwithstanding any other provisions in this Indenture, no permanent
global Security may be exchanged in whole or in part for Securities registered,
and no transfer of a permanent global Security in whole or in part may be
registered, in the name of any Person other than the Depositary for such
permanent global Security or a nominee thereof unless (i) the Depositary
notifies the Company pursuant to Clause 3.05(c) of this Section that it is
unwilling or unable to continue as Depositary for such permanent global
Security or if at any time the Depositary ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, as amended, (ii) if the
Company in its sole discretion determines pursuant to Clause 3.05(d) of this
Section that such permanent global Security shall be so exchangeable or
transferrable and executes and delivers to the Security Registrar a Company
Order providing that such permanent global Security shall be so exchangeable or
transferrable, (iii) any event shall have occurred and be continuing which,
after notice or lapse of time, or both, would become an Event of Default with
respect to the Securities of the series of which such permanent global Security
is a part or (iv) there shall exist such circumstances, if any, in addition or
in lieu of the foregoing as have been specified for this purpose as
contemplated by Section 3.01.

     (c) Subject to Clause 3.05(a) above, any exchange of a permanent global
Security for other Securities may be made in whole or in part, and all
Securities issued in exchange for a permanent global Security or any portion
thereof shall be registered in such names as the Depositary for such permanent
global Security shall direct. The Trustee shall deliver such Securities to or
as directed by the Persons in whose names such Securities are so registered.

     (d) If at any time the Depositary for any Securities of a series
represented by one or more global Securities notifies the Company that it is
unwilling or unable to continue as Depositary for such Securities or if at any
time the Depositary ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, the Company shall appoint a
successor Depositary with respect to such Securities. If a successor Depositary
for such Securities is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such ineligibility (and in any
event before the Depositary surrenders such global Security for exchange), the
Company's election that such Securities be represented

                                       25
<PAGE>

by one or more global Securities shall no longer be effective and the Company
shall execute, and the Trustee, upon receipt of an Officers' Certificate for
the authentication and delivery of definitive Securities of such series, will
authenticate and deliver, Securities of such series in definitive registered
form without coupons, in any authorized denominations, in an aggregate
principal amount equal to the principal amount of the global Security or
Securities representing such Securities in exchange for such global Security or
Securities.

     (e) The Company may at any time and in its sole discretion determine that
the Securities of any series issued in the form of one or more global
Securities shall no longer be represented by a global Security or Securities.
In such event the Company will execute, and the Trustee, upon receipt of an
Officers' Certificate for the authentication and delivery of definitive
Securities of such series, will authenticate and deliver Securities of such
series in definitive registered form, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the global Security
or Securities representing such Securities, in exchange for such global
Security or Securities.

     (f) Subject to Clause 3.05(a) above, with respect to Securities
represented by a global Security, the Depositary for such global Security may
surrender such global Security in exchange in whole or in part for Securities
of the same series in definitive registered form on such terms as are
acceptable to the Company and such Depositary. Thereupon, the Company shall
execute, and the Trustee shall authenticate and deliver, without service
charge,

          (i) to the Person specified by such Depositary a new Security or
     Securities of the same series, of any authorized denomination as requested
     by such Person, in an aggregate principal amount equal to and in exchange
     for such Person's beneficial interest in the global Security; and

          (ii) to such Depositary a new global Security in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     global Security and the aggregate principal amount of Securities
     authenticated and delivered pursuant to clause 3.05(f)(i) above.

     Upon the exchange of a global Security for Securities in definitive
registered form, in authorized denominations, such global Security shall be
canceled by the Trustee.

     (g) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a permanent 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

                                       26
<PAGE>

permanent global Security, unless such Security is registered in the name of a
Person other than the Depositary for such permanent 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 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

     Unless otherwise provided as contemplated by Section 3.01 with respect to
any Security, interest on such Security which is payable, and is punctually
paid or

                                       27
<PAGE>

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; provided
that if that Security or its Predecessor Security was originally issued on a
date after a Regular Record Date and before the following Interest Payment
Date, the first payment of interest on such Security will be made on the
Interest Payment Date following the next succeeding Regular Record Date. Unless
otherwise specified as contemplated by Section 3.01 for any Security, interest
payable at Maturity (other than on a date which is an Interest Payment Date)
will be paid to the same Person to whom the principal amount of this Security
is payable.

     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 (a) or (b) below:

     (a) 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 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 mailed, first-class postage prepaid, to each Holder of
Securities of such series at his address as it appears in the Security
Register, 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
3.07(b).

                                       28
<PAGE>

     (b) 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.

     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.

     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 premium, if any) and
(subject to Section 3.07) interest on such Security and for all other purposes
whatsoever, whether or not such Security is 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, 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 canceled 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 canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of as directed by a Company
Order.

                                       29
<PAGE>

     SECTION 3.10. Computation of Interest

     Except as otherwise specified as contemplated by Section 3.01 for any
Security, interest on the Securities of each series shall be computed on the
basis of a 360-day year consisting of 12 30-day months.

                           SATISFACTION AND DISCHARGE

     SECTION 4.01. Satisfaction and Discharge of Indenture

     This Indenture shall upon Company Request cease to be of further effect
(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, when

     (a) either

          (i) all Securities theretofore authenticated and delivered (other
     than (x) Securities which have been destroyed, lost or stolen and which
     have been replaced or paid as provided in Section 3.06 and (y) Securities
     for whose payment money has theretofore been deposited in trust or
     segregated and held in trust by the Company and thereafter repaid to the
     Company or discharged from such trust, as provided in Section 10.03) have
     been delivered to the Trustee for cancellation; or

          (ii) all such Securities not theretofore delivered to the Trustee for
     cancellation

               (A) have become due and payable, or

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

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

                                       30
<PAGE>

     and the Company, in the case of (A), (B) or (C) above has deposited or
     caused to be deposited with the Trustee as trust funds in trust for the
     purpose 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 or 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;

     (b) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

     (c) the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Sections 4.03(b) and 6.07, the
obligations of the Trustee to any Authenticating Agent under Section 6.14 and,
if money shall have been deposited with the Trustee pursuant to subclause
4.01(a)(ii), the obligations of the Trustee under Section 4.03 and the last
paragraph of Section 10.03 shall survive.

     SECTION 4.02. Defeasance of Securities of Any Series

     Unless otherwise specified pursuant to Section 3.01 with respect to any
Security, then notwithstanding Section 4.01, the Company shall be deemed to
have paid and discharged the entire indebtedness on all the Outstanding
Securities of any series on the 91st day after the date of the deposit referred
to in subparagraph 4.02(d) hereof, and the provisions of this Indenture, as it
relates to such Outstanding Securities, shall no longer be in effect (and the
Trustee, at the expense of the Company, shall at Company Request, execute
proper instruments acknowledging the same) (hereinafter called "Defeasance"),
except as to:

     (a) the rights of Holders of Securities to receive, from the trust funds
described in subparagraph 4.02(d) hereof, (i) payment of the principal of and
any premium or interest on the Outstanding Securities of that series on the
Stated Maturity of such principal or installment of principal or interest and
(ii) the benefit of any mandatory sinking fund payments or analogous payments
applicable to Securities of such series on the day on which such payments are
due and payable in accordance with the terms of the Indenture and such
Securities;

                                       31
<PAGE>

     (b) the Company's obligations with respect to such Securities under
Sections 3.05, 3.06, 4.03, 10.02 and 10.03; and

     (c) the rights, powers, trusts, duties and immunities of the Trustee
hereunder;

     provided that the following conditions have been satisfied:

     (d) with reference to this provision, the Company has irrevocably
deposited or caused to be irrevocably deposited with the Trustee as trust funds
for the purpose of making the following payments, specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of the
Securities of that series, (i) money in an amount, or (ii) U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide not later than one day
before the due date of any payment referred to in clause (A) or (B) of this
subparagraph 4.02(d) money in an amount, or (iii) a combination thereof,
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
for such purposes, (A) the principal of and any premium or interest on the
Outstanding Securities of that series on the Stated Maturity of such principal
or installment of principal or interest on the Redemption Date, as the case may
be, and (B) any mandatory sinking fund payments or analogous payments
applicable to Securities of such series on the day on which such payments are
due and payable, each in accordance with the terms of this Indenture and of
such Securities;

     (e) such Defeasance shall not cause the Trustee with respect to the
Securities of that series to have a conflicting interest as defined in Section
6.08 and for purposes of the Trust Indenture Act with respect to the Securities
of any series;

     (f) such Defeasance will not result in a breach or violation of, or
constitute a default under, this Indenture or any other agreement or instrument
to which the Company is a party or by which it is bound;

     (g) such Defeasance would not cause any Outstanding Security of such
series then listed on any nationally recognized securities exchange to be then
delisted as a result thereof;

     (h) no Event of Default or event which with notice or lapse of time would
become an Event of Default with respect to Securities of the series shall have
occurred and be continuing on the date of such deposit or during the period
ending on the 91st day after such date;

                                       32
<PAGE>

     (i) the Company has delivered to the Trustee an Opinion of Counsel based
on the fact that (x) the Company has received from, or there has been published
by, the Internal Revenue Service a ruling or (y) since the date hereof, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and such opinion shall confirm that, the Holders of the
Securities of such series will not recognize income, gain or loss for Federal
income tax purposes as a result of such deposit, defeasance and discharge and
will be subject to Federal income tax on the same amount and in the same manner
and at the same times, as would have been the case if such deposit, defeasance
and discharge had not occurred;

     (j) the Company has delivered to the Trustee an Opinion of Counsel stating
that (i) such deposit, defeasance and discharge would not cause any outstanding
Security of such series then listed on any nationally recognized securities
exchange to be delisted as a result thereof; and (ii) and that such Defeasance
would not result in the trust arising from such deposit constituting an
investment company within the meaning of the Investment Company Act of 1940, as
amended from time to time;

     (k) the Company has delivered to the Trustee an Opinion of Counsel to the
effect that after the 91st day following the deposit, the trust funds will not
be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally, except
that if a court were to rule under any such law in any case or proceeding that
the trust funds remained property of the Company, no opinion is given as to the
effect of such laws on the trust funds except the following: (A) assuming such
trust funds remained in the Trustee's possession prior to such court ruling to
the extent not paid to Holders of Securities, the Trustee will hold, for the
benefit of such Holders, a valid and perfected security interest in such trust
funds that is not avoidable in bankruptcy or otherwise, and (B) such Holders
will be entitled to receive adequate protection of their interests in such
trust funds if such trust funds are used; and

     (l) the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent provided for
relating to the Defeasance contemplated by this provision have been complied
with.

     SECTION 4.03. Application of Trust Funds; Indemnification

     (a) Subject to the provisions of the last paragraph of Section 10.03, all
money deposited with the Trustee pursuant to Section 4.01, all money and U.S.
Government Obligations deposited with the Trustee pursuant to Section 4.02 or
Section 10.06 and all money received by the Trustee in respect of U.S.
Government Obligations deposited with the Trustee pursuant to Section 4.02 or
Section 10.06 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto of
the principal (and premium, if any) and interest for whose payment such money
has been deposited with or received by the Trustee or to make mandatory sinking
fund payments or analogous payments as contemplated by Section 4.02 or Section
10.06, as the case may be.

     (b) The Company shall pay and shall indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against U.S. Government Obligations
deposited pursuant to Section 4.02 or Section 10.06 or the interest and
principal received in respect of such obligations other than any payable by or
on behalf of Holders.

     (c) The Trustee shall deliver or pay to the Company from time to time upon
Company Request any money or U.S. Government Obligations held by it as provided
in Section 4.02 or 10.06 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are then in excess of the amount which then would
have been required to be deposited for the purpose for which such money or U.S.
Government Obligations were deposited or received.

     SECTION 4.04. Reinstatement

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 4.02 or 10.06 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 or upon the occurrence of
an Event of Default, then the obligations under this Indenture and such
Securities from which the Company has been discharged or released pursuant to
Section 4.02 or 10.06 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 4.03 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

                                       34
<PAGE>

subrogated to the rights (if any) of the Holders of such Securities to receive
such payment from the money so held in trust.

                                    REMEDIES

     SECTION 5.01. Events of Default

     "Event of Default," wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or
governmental body):

     (a) default in the payment of any interest upon any Security of that
series when it becomes due and payable, and continuance of such default for a
period of 30 days; or

     (b) default in the payment of the principal of (or premium, if any, on)
any Security of that series at its Maturity; or

     (c) default in the deposit of any sinking fund payment, when and as due by
the terms of a Security of that series; or

     SECTION 5.02. Acceleration of Maturity; Rescission and Annulment

     If an Event of Default described in clause 5.01(a), 5.01(b), 5.01(c),
5.01(d) or 5.01(g) 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 such series (each such series voting as a separate class in the
case of an Event of Default under clause 5.01(a), 5.01(b), 5.01(c) or 5.01(g),
and all such series voting as one class in the case of such an Event of Default
under clause 5.01(d)) may declare the principal amount (or, if any Securities
are Original Issue Discount Securities, such portion of the principal amount as
may be specified in the terms of such Securities) of all of the Securities of
such series 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 any Event of Default described in clause 5.01(d) with respect to
all series of Securities then Outstanding, or any Event of Default described in
clause 5.01(e) or 5.01(f) occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in aggregate principal amount of
all the Outstanding Securities (voting as one class) may declare the principal
amount (or, if any Securities are

                                       36
<PAGE>

Original Issue Discount Securities, such portion of the principal amount as may
be specified in the terms of such Securities) of all the Securities then
Outstanding 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.

     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

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

          (i) the overdue interest on all Securities of the series,

          (ii) 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 interest thereon at the interest rate or rates prescribed
     in such Securities,

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

          (iv) all sums paid or advanced by the Trustee hereunder and the
     reasonable compensation, expenses, disbursements and advances of the
     Trustees, its agents and counsel and all other amounts due under Section
     6.07;

     and

     (b) 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.

                                       37
<PAGE>

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

     The Company covenants that if

     (a) 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

     (b) 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 premium, if any) and interest and, to the
extent that payment of such interest shall be legally enforceable, interest on
any overdue principal (and premium, if any) and on any overdue interest, at the
rate or rates 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, other than those incurred due
to the Trustee's bad faith or negligence.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

     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 therein, or to enforce any other proper remedy.

     SECTION 5.04. Trustee May File Proofs of Claim

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial

                                       38
<PAGE>

proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Securities shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

     (a) to file and prove a claim for the whole amount of principal (and
premium, if any) and interest owing and unpaid in respect of the Securities and
to file such other papers or documents as may be necessary or advisable in
order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and of the Holders allowed in such judicial proceeding, and

     (b) 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.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holders hereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

     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, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

                                       39
<PAGE>

     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 premium,
if any) 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 all amounts due the Trustee under this
     Indenture; and

          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest on the Securities in
     respect of which or for the benefit of which such money has been collected
     ratably without preference or priority of any kind according to the
     amounts due and payable on such Securities for principal (and premium, if
     any) and interest, respectively.

     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

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

     (b) 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;

     (c) 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;

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

     (e) 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 all Outstanding Securities of that series;

                                       40
<PAGE>

     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 premium, if any) and (subject to Section 3.07)
interest on such Security on the Stated Maturity or 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 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.

<PAGE>

     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 which shall
have occurred and shall be continuing 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

     (a) such direction shall not be in conflict with any rule of law or with
this Indenture,

     (b) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

     (c) the Trustee shall have the right to decline any direction with respect
to which a Responsible Officer reasonably determines such direction will cause
the Trustee to incur any liability for which it shall not have been adequately
indemnified pursuant to Section 5.07.

     SECTION 5.13. Waiver of Past Defaults

     The Holders of (i) not less than a majority in principal amount of the
Outstanding Securities of any series (each such series voting as a separate
class) may on behalf of the Holders of all Securities of such series waive any
past default or Event of Default described in clause 5.01(d) which relates to
less than all series of Outstanding Securities or described in clause 5.01(g)
with respect to such series and its consequences, or (ii) not less than a
majority in principal amount of the Outstanding Securities affected thereby
(voting as one class) may on behalf of the Holders of all the Outstanding
Securities affected thereby waive any past default or Event of Default
described in said clause 5.01(d) which relates to all such Outstanding
Securities and its consequences, except in any such case a default

                                       42
<PAGE>

     (a) in the payment of the principal of, or any premium or interest on, any
Security of such series, or

     (b) in respect of a covenant or provision hereof which under Article 9
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

     All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, 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, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 25% in
principal amount of the Outstanding Securities of any series or to any suit
instituted by any Holder for the enforcement of the payment of the principal of
(or premium, if any) or interest on any Security on or after the Stated
Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

     SECTION 5.15. Waiver of Usury, Stay or Extension Law

     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 stay or extension of 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.

     SECTION 6.01. Certain Duties and Responsibilities

     (a) Except during the continuance of an Event of Default,

          (i) the Trustee undertakes to perform such duties and only such
     duties as specifically set forth in this Indenture, and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

          (ii) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness
     of the opinions expressed therein, upon certificates or opinions furnished
     to the Trustee and conforming to the requirements of this Indenture; but
     in the case of any such certificates or opinions which by any provision
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall be under a duty to examine the same to determine whether or
     not they conform to the requirements of this Indenture.

     (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

     (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that

          (i) this Subsection shall not be construed to limit the effect of
     Subsection 6.01(a);

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

          (iii) the Trustee shall not be liable with respect to any action
     taken or omitted to be taken by it in good faith in accordance with the
     direction of the Holders of a majority in principal amount of the
     Outstanding Securities of any series, determined as provided in Section
     5.12, relating to the time, method and place of conducting any proceeding
     for any remedy available to the Trustee, or exercising any trust or power
     conferred upon the Trustee, under this Indenture with respect to the
     Securities of such series; and

                                       44
<PAGE>

          (iv) 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.

     (d) 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

     Within 90 days after receipt by the Trustee of written notice of the
occurrence of any default hereunder with respect to the Securities of any
series the Trustee shall transmit in the manner and to the extent provided in
Section 7.03(d), notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, except
in the case of a default in the payment of the principal of (or premium, if
any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interest of the Holders of Securities of
such series; and provided, further, that in the case of any default of the
character specified in Section 5.01(d) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term "default,"
means any event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to Securities of such series.

     SECTION 6.03. Certain Rights of Trustee

     Subject to the provisions of Section 6.01:

liabilities which might be incurred by it in compliance with such request or
direction;

facts or matters stated in any resolution, certificate, statement, instrument,

indemnification, together

                                       46
<PAGE>

with the Trustee's right to compensation, shall survive the Trustee's
resignation or removal and final payment of the Securities.

certificates of authentication, shall be taken as the statements of the
Company, and the Trustee or any Authenticating Agent assumes no responsibility

or sufficiency of this Indenture or of the Securities. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

by any provision of law in regard to the compensation of a trustee of an
express trust);

     (b) 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
expenses, disbursements or advances as may be attributable to its negligence or
bad faith;

                                       47
<PAGE>

     (c) 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

     (d) The Trustee shall have, and is hereby granted, a first priority lien
on all monies, securities and collateral (other than monies held in trust by
the Trustee for the purpose of paying the principal, premium, if any, and
interest on any specific Securities) held by or on behalf of the Trustee
pursuant to this Indenture for payment or reimbursement to the Trustee of its
fees, expenses and any other monies payable to it hereunder.

     SECTION 6.08. Disqualification; Conflicting Interest

     (a) If the Trustee has or shall acquire any conflicting interest within
the meaning of the Trust Indenture Act with respect to the Securities of any
series, it shall, within 90 days after ascertaining that it has such
conflicting interest, either eliminate such conflicting interest or resign with
respect to the Securities of that series in the manner and with the effect
hereinafter specified in this Article.

     (b) In the event that the Trustee shall fail to comply with the provisions
of Subsection 6.08(a) with respect to the Securities of any series, the Trustee
shall, within 10 days after the expiration of such 90-day period, transmit by
mail to all Holders of Securities of that series, as their names and addresses
appear in the Security Register, notice of such failure.

     SECTION 6.09. Corporate Trustee Required; Eligibility

     There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000 subject to supervision or examination by Federal or
State authority and having its Corporate Trust Office in any State in the
United States of America or in the District of Columbia. If such corporation
publishes or files 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 corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published or filed. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section,
it

                                       48
<PAGE>

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.

     (d) If at any time:

          (i) the Trustee shall fail to comply with Section 6.08(a) 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

          (ii) 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

          (iii) 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, (A) the Company, by a Board Resolution, may remove the
Trustee with respect to the applicable series of Securities, or (B) subject to
Section 5.14, any Holder who has been a bona fide Holder of a Security of any
series 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 such series of Securities and the
appointment of a successor Trustee or Trustees.

                                       49
<PAGE>

     (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 by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. 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

     (a) 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

                                       50
<PAGE>

the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder.

     (b) 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 (1)
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, (2) 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 (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, 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.

     (c) 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
paragraph 6.11(a) or 6.11(b), as the case may be.

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

                                       51
<PAGE>

     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.

     SECTION 6.13. Preferential Collection of Claims

     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 other obligor).

     SECTION 6.14. Appointment of Authenticating Agent

     At any time 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, 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 shall 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

                                       52
<PAGE>

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 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 such Authenticating Agent.

     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 shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. 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.

     The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

     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 alternate
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' LIST 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

     (a) semi-annually a list, in such form as the Trustee may reasonably
require, of the names and addresses of the Holders as of the date of such list,
and

     (b) 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

     (a) 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 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.

     (b) If three or more Holders of Securities of any series (herein referred
to as "applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Security of such series
for a period of at least six months preceding the date of such application, and
such application states that the applicants desire to communicate with other
Holders of such series or with Holders of all other series of Securities with
respect to their rights under this Indenture or under such Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within five business
days after the receipt of such application, at its election, either

          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), or

          (ii) inform such applicants as to the approximate number of Holders
     of such series of Securities or Holders of all other series of Securities
     whose names and addresses appear in the information preserved

                                       55
<PAGE>

     at the time by the Trustee in accordance with Section 7.02(a), and as to
     the approximate cost of mailing to the Holders of such series of
     Securities or the Holders of all series of Securities the form of proxy or
     other communication, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder of such series of Securities or of all series of Securities
or of all series of Securities whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 7.02(a) a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion
of the Trustee, such mailing would be contrary to the best interest of the
relevant Holders or would be in violation of applicable law. Such written
statement shall specify the basis of such opinion. If the Commission, after
opportunity for a hearing upon the objections specified in the written
statement so filed, shall enter an order refusing to sustain any of such
objections or if, after the entry of an order sustaining one or more of such
objections, the Commission shall find, after notice and opportunity for
hearing, that all the objections so sustained have been met and shall enter an
order so declaring, the Trustee shall mail copies of such material to all such
Holders with reasonable promptness after the entry of such order and the
renewal of such tender; otherwise the Trustee shall be relieved of any
obligation or duty to such applicants respecting their application.

     (c) 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 agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 7.02(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section
7.02(b).

     SECTION 7.03. Reports by Trustee

     (a) If required under Section 313(a) of the Trust Indenture Act, within 60
days after May 15 of each year commencing with the year 2001, so long as any of
the Securities are outstanding, the Trustee shall transmit by mail to all
Holders, as provided in subsection 7.03(c), a brief report dated as of such May
15 with respect to any of the following events which may have occurred within
the

                                       56

     of or any material change to its qualifications under Section 6.08;

          (ii) the character and amount of any advances (and if the Trustee
     elects so to state, the circumstances surrounding the making thereof) made

     and for the reimbursement of which it claims or may claim a lien or
     charge, prior to that of the Securities, on any property or funds held or
     collected by it as Trustee, except that the Trustee shall not be required
     (but may elect) to report such advances if such advances so remaining
     unpaid aggregate not more than one-half of one percent of the principal
     amount of the Securities Outstanding of such series on the date of such
     report;

          (iii) any change to the amount, interest rate and maturity date of
     all other indebtedness owing by the Company (or by any other obligor on

     security therefor, except an indebtedness based upon a creditor
     relationship arising in any manner described in Section 6.13;

     possession of the Trustee as such on the date of such report;

          (v) any additional issue of Securities which the Trustee has not
     previously reported; and

          (vi) any action taken by the Trustee in the performance of its duties
     hereunder which it has not previously reported and which in its opinion
     materially affects the Securities, except action in respect of a default,
     notice of which has been or is to be withheld by the Trustee in accordance
     with Section 6.02.

     (b) The Trustee shall transmit by mail to all Holders, as provided in

the last report transmitted pursuant to Subsection 7.03(a) (or if no such
report has yet been so transmitted, since the date of execution of this
instrument) for the reimbursement of which it claims or may claim a lien or
charge, prior to that of the Securities, on property or funds held or collected
by it as Trustee and which it has not previously

                                       57
<PAGE>

required (but may elect) to report such advances if such advances remaining
unpaid at any time aggregate 10% or less of the principal amount of the
Securities Outstanding of such series at such time, such report to be
transmitted within 90 days after such time.

     (c) Reports pursuant to this Section shall be transmitted by mail:

          (i) to all Holders of Securities, as the names and addresses of such
     Holders appear in the Security Register as of a date not more than fifteen
     days prior to the mailing thereof;

     (d) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Company. The Company
will notify the Trustee when any Securities are listed on any stock exchange.

the foregoing as the Commission may from time to time by rules and regulations
prescribe) which the Company may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934;

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

     Subject to the provisions of Section 8.03, nothing contained in this

successive consolidations or mergers in which the Company or its successor or
successors shall be a party or parties or shall prevent any sale or conveyance
of all or substantially all of the property of the Company to any other

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 such corporation shall expressly assume the due and punctual
payment of the principal of, and premium, if any, 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 by supplemental indenture satisfactory to the Trustee,
executed and delivered to the Trustee by such corporation, and (ii) 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 shall not immediately
thereafter have outstanding any secured Debt

                                       59
<PAGE>

(as defined in Section 10.04) not expressly permitted by the provisions of
Section 10.04 unless the provisions of Section 8.03 shall previously have been
complied with.

     SECTION 8.02. Successor Corporation to be Substituted for Company

     In case of any such consolidation, merger, sale or conveyance (other than
a conveyance by way of lease) and upon any such assumption by the successor
corporation, such successor corporation shall succeed to and be substituted for
the Company, with the same effect as if it had been named herein as the party
of the first part, and the Company thereupon shall be relieved of any further
liability or obligation hereunder or upon the Securities and 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 Masco Corporation, any or all of the Securities issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee or the Authenticating Agent; 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 or
the Authenticating Agent shall authenticate and deliver any Securities which
previously shall have been signed and delivered by the officers of the Company
to the Trustee or the Authenticating Agent for authentication, and any
Securities which such successor corporation thereafter shall cause to be signed
and delivered to the Trustee or the Authenticating Agent 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 the case of any such consolidation, merger, sale or conveyance, such
change 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. Securities to be Secured in Certain Events

     If, upon any such consolidation or merger of the Company with or into any
other corporation, or upon any sale or conveyance of the property of the
Company as an entirety or substantially as an entirety to any other
corporation, any Principal Property or any shares of stock or indebtedness of
any Consolidated Subsidiary owning any Principal Property owned immediately
prior thereto would thereupon become subject to any mortgage (as defined in
Section 10.04), unless the Company could create such mortgage pursuant to
Section 10.04 without equally and ratably securing the Securities, the Company,
prior to or simultaneously with

                                       60
<PAGE>

such consolidation, merger, sale or conveyance, will secure the Securities
outstanding hereunder, equally and ratably with any other obligation of the
Company or any such Subsidiary then entitled thereto, prior to the Debt (as
defined in Section 10.04) secured by such mortgage.

     SECTION 8.04. Evidence to be Furnished to the Trustee

     The Trustee, subject to the provisions of Sections 6.01 and 6.03, may
receive and rely upon an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any consolidation, merger, sale or conveyance, and any
such assumption complies with the provisions of this Article 8.

                            SUPPLEMENTAL INDENTURES

     SECTION 9.01. Supplemental Indentures without Consent of Holders

     Without the consent of any Holders, the Company, when authorized by a
Board Resolution, 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 any of the following purposes:

     (a) to evidence the succession of another corporation to the Company and
the assumption by any such successor of the covenants of the Company herein and
in the Securities; or

     (b) 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

     (c) 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 the relevant series) or to surrender any right or power herein
conferred upon the Company; or

     (d) 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

                                       61
<PAGE>

bearer form, registrable or not registrable as to principal, and with or
without interest coupons, or permit or facilitate the issuance of Securities in
uncertificated form; or

     (e) to add to, change or eliminate any of the provisions of this Indenture
in respect of one or more series of Securities, provided that any such
addition, change or elimination (A) shall neither (i) apply to Securities 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 such Securities with respect to such provision or (B) shall become
effective only when there is no such Security Outstanding; or

     (f) to secure the Securities pursuant to the requirements of Sections 8.03
or otherwise; or

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

     (h) to evidence and provide for the acceptance of appointment hereunder by
a successor Trustee with respect to the Securities of one or more series and to
add to or change any of the provisions of this Indenture as shall be necessary
to provide for and facilitate the administration of the trusts hereunder by
more than one Trustee, pursuant to the requirements of Section 6.11(b); or

     (i) to cure any ambiguity, to correct or supplement any provision herein
which may be inconsistent with any other provision herein, or to make any other
provisions with respect to matters or questions arising under this Indenture;
provided such action 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 voting as one class, by Act of said Holders delivered to
the Company and the Trustee, the Company, when authorized by a Board
Resolution, 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 of
modifying in any manner the rights of the Holders of Securities of such series
under the Indenture; provided, however, that no such supplemental indenture
shall, without the consent of the Holder of each Outstanding Security affected
thereby,

                                       62
<PAGE>

     (a) 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 that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 5.02, or change any
Place of Payment where, or the coin or currency in which, any Security or any
premium or the 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

     (b) 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

     (c) modify any of the provisions of this Section or Section 5.13, except
to increase any such percentage or to provide that certain other provisions of
this Indenture cannot be modified or waived without 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, or the deletion of this proviso, in accordance with the requirements
of Sections 6.11(b) and 9.01(h).

     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

                                       63
<PAGE>

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 as then in effect.

     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 (and premium, if any) and any interest on each of the Securities
of that series in accordance with the terms of the Securities and this
Indenture.

                                       64
<PAGE>

     SECTION 10.02. Maintenance of Office or Agency

     The Company will maintain in each 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 and
the Holders 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 and surrenders of Securities of that series and notices and
demands may be made or served at the Corporate Trust Office 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
designation; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or
agency in each Place of Payment for Securities of any series for such purposes.
The Company will give prompt written notice to the Trustee and the Holders 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

     (a) If the Company shall appoint a paying agent other than the Trustee
with respect to the Securities of any series, it will cause such paying agent
to execute and deliver to the Trustee an instrument in which such agent shall
agree with the Trustee, subject to the provisions of this Section 10.03:

          (i) that it will hold all sums held by it as such agent for the
     payment of the principal of and premium, if any, or interest, if any, on
     the Securities of such series (whether such sums have been paid to it by
     the Company or by any other obligor on the Securities of such series) in
     trust for the benefit of the holders of the Securities of such series;

          (ii) that it will give the Trustee notice of any failure by the
     Company (or by any other obligor on the Securities of such series) to make
     any payment of the principal of and premium, if any, or interest, if any,
     on the Securities of such series when the same shall be due and payable;
     and

                                       65
<PAGE>

          (iii) at any time during the continuance of any such default, upon
     the written request of the Trustee, forthwith pay to the Trustee all sums
     so held in trust by such Paying Agent.

     (b) If the Company shall at any time act as its own Paying Agent it will,
on or before each due date of the principal of (and premium, if any) or
interest, if any, on the Securities of any series, set aside, segregate and
hold in trust for the benefit of the Persons entitled thereto a sum sufficient
to pay such principal (and premium, if any) or interest so becoming due and
will notify the Trustee of any failure to take such action and of any failure
by the Company (or by any other obligor under the Securities of such series) to
make any payment of the principal of and premium, if any, or interest, if any,
on the Securities of such series when the same shall become due and payable.

     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 (except pursuant to Section 4.02 or
10.06) or any Paying Agent, or then held by the Company, in trust for the
payment of the principal of (and premium, if any) or interest on any Security
of any series and remaining unclaimed for two years after such principal (and
premium, if any) 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 the Borough of Manhattan, The City of 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.

     SECTION 10.04. Limitations on Liens

     (a) The Company will not, nor will it permit any Consolidated Subsidiary
to, issue, assume or guarantee any debt for money borrowed or any Funded Debt
(hereinafter in this Article 10 referred to as "Debt"), secured by a mortgage,
security interest, pledge, lien or other encumbrance (mortgages, security
interests, pledges, liens and other encumbrances being hereinafter called a
"mortgage" or "mortgages") upon any Principal Property or upon any shares of
stock or indebtedness of any Consolidated Subsidiary which owns or leases a
Principal Property (whether such Principal Property, shares of stock or
indebtedness are now owned or hereafter acquired) without in any such case
effectively providing concurrently with the issuance, assumption or guaranty of
any such Debt that the Securities (together with, if the Company shall so
determine, any other indebtedness of or guaranteed by the Company or such
Consolidated Subsidiary ranking equally with the Securities and then existing
or thereafter created) shall be secured equally and ratably with such Debt;
provided, however, that the foregoing restrictions shall not apply to Debt
secured by

          (i) mortgages on property, shares of stock or indebtedness of any
     corporation existing at the time such corporation becomes a Consolidated
     Subsidiary;

          (ii) mortgages on property existing at the time of acquisition of
     such property by the Company or a Consolidated Subsidiary, or mortgages to
     secure the payment of all or any part of the purchase price of such
     property upon the acquisition of such property by the Company or a
     Consolidated Subsidiary or to secure any Debt incurred by the Company or
     Consolidated Subsidiary prior to, at the time of, or within 120 days after
     the later of the acquisition, the completion of construction (including
     any improvements on an existing property) or the commencement of
     commercial operation of such property, which Debt is incurred for the
     purpose of financing all or any part of the purchase price thereof or
     construction or improvements thereon; provided, however, that in the case
     of any such acquisition, construction or improvement, the mortgage shall
     not apply to any property theretofore owned by the Company or a
     Consolidated Subsidiary, other than any property on which the property so
     constructed or the improvement is located or to which the property so
     constructed or the improvement is appurtenant;

          (iii) mortgages securing Debt of a Consolidated Subsidiary owing to
     the Company or to another Consolidated Subsidiary;

                                       67
<PAGE>

          (iv) mortgages on property of a corporation existing at the time such
     corporation is merged or consolidated with the Company or a Consolidated
     Subsidiary or at the time of a sale, lease or other disposition of the
     properties of a corporation or firm as an entirety or substantially as an
     entirety to the Company or a Consolidated Subsidiary; provided, however,
     that no such mortgage shall extend to any other Principal Property of the
     Company or any Consolidated Subsidiary or to any shares of capital stock
     or any indebtedness of any Consolidated Subsidiary which owns or leases a
     Principal Property;

          (v) mortgages on property of the Company or a Consolidated Subsidiary
     in favor of the United States of America or any State thereof, or any
     department, agency or instrumentality or political subdivision of the
     United States of America or any State thereof, or in favor of any other
     country, or any political subdivision thereof, to secure partial,
     progress, advance or other payments pursuant to any contract or statute
     (including Debt of the pollution control or industrial revenue bond type)
     or to secure any indebtedness incurred for the purpose of financing all or
     any part of the purchase price or the cost of construction of the property
     subject to such mortgages; or

          (vi) any extension, renewal or replacement (or successive extensions,
     renewals or replacements) in whole or in part of mortgages existing at the
     date of this Indenture, or any mortgage referred to in the foregoing
     clauses (i) through (v), inclusive, provided, however, that the principal
     amount of Debt secured thereby shall not exceed the principal amount of
     Debt so secured at the time of such extension, renewal or replacement, and
     that such extension, renewal or replacement shall be limited to all or a
     part of the property which secured the mortgage so extended, renewed or
     replaced (plus improvements on such property).

     (b) Notwithstanding the foregoing provisions of this Section 10.04, the
Company may, and may permit any Consolidated Subsidiary to, issue, assume or
guarantee Debt secured by a mortgage not excepted by clauses (i) through (vi)
of paragraph (a) above without equally and ratably securing the Securities,
provided, however, that the aggregate principal amount of all such Debt then
outstanding, plus the aggregate principal amount of the Debt then being issued,
assumed, or guaranteed, and the aggregate amount of the Attributable Debt in
respect of sale and lease-back arrangements, shall not exceed 5% of
Consolidated Net Tangible Assets, determined as of a date not more than 90 days
prior thereto.

                                       68
<PAGE>

     SECTION 10.05. Limitation on Sale and Leaseback

     The Company will not, nor will it permit any Consolidated Subsidiary to,
enter into any arrangement with any person providing for the leasing by the
Company or any Consolidated Subsidiary of any Principal Property (whether such
Principal Property is now owned or hereafter acquired) (except for leases for a
term of not more than three years and except for leases between the Company and
a Consolidated Subsidiary or between Consolidated Subsidiaries), which property
has been or is to be sold or transferred by the Company or such Consolidated
Subsidiary to such person, unless (a) the Company or such Subsidiary would be
entitled, pursuant to the provisions of Section 10.04, to issue, assume or
guarantee Debt secured by a mortgage upon such property at least equal in
amount to the Attributable Debt in respect of such arrangement without equally
and ratably securing the Securities or (b) the Company or a Consolidated
Subsidiary, within 120 days of the effective date of any such arrangement,
applies an amount equal to the greater of the net proceeds of the sale of the
Principal Property leased pursuant to such arrangement or the fair market value
of the Principal Property so leased at the time of entering into such
arrangement (as determined by the Board of Directors of the Company) to the
retirement (other than any mandatory retirement or by way of payment at
maturity) of Funded Debt of the Company or any Consolidated Subsidiary (other
than Funded Debt owned by the Company or any Consolidated Subsidiary and other
than Funded Debt subordinated in the payment of principal or interest to the
Securities and except that no Security shall be retired if such retirement of
Securities pursuant to this provision would be prohibited by the resolutions or
supplemental indentures referred to in Section 3.01), provided, however, that
in lieu of applying all or any part of such net proceeds or fair market value
to such retirement, the Company may at its option (i) deliver to the Trustee
Securities theretofore purchased or otherwise acquired by the Company, or (ii)
receive credit for Securities theretofore redeemed pursuant to the resolutions
or supplemental indentures referred to in Section 3.01 hereof, which Securities
have not theretofore been made the basis for the reduction of a sinking fund
payment pursuant to Article 12 or applied in lieu of retiring Funded Debt
pursuant hereto. If the Company shall so deliver Securities to the Trustee (or
receive credit for Securities so delivered), the amount of cash which the
Company shall be required to apply to the retirement of Funded Debt pursuant to
this Section 10.05 shall be reduced by an amount equal to the aggregate
principal amount of such Securities.

     SECTION 10.06. Defeasance of Certain Obligations

     The Company may omit to comply, on or after the date the conditions set
forth in subsections (a) to (f) of this Section 10.06 are satisfied, with any
term, provision or condition set forth in any negative or restrictive covenant
of the

                                       69
<PAGE>

Company applicable to the Securities of such series (hereafter called "Covenant
Defeasance") that is specified pursuant to Section 3.01(j), if

     (a) With reference to this Section 10.06, the Company has irrevocably
deposited or caused to be irrevocably deposited with the Trustee as trust funds
for the purpose of making the following payments, specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of the
Securities of that series, (i) money in an amount, or (ii) U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide not later than one day
before the due date of any payment referred to in clause (A) or (B) of this
subparagraph 10.06(a) money in an amount, or (iii) a combination thereof,
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
for such purposes, (A) the principal of and any premium or interest on the
Outstanding Securities of that series on the Stated Maturity of such principal
or installment of principal or interest or the Redemption Date, as the case may
be, and (B) any mandatory sinking fund payments or analogous payments
applicable to Securities of such series on the day on which such payments are
due and payable, each in accordance with the terms of this Indenture and of
such Securities;

     (b) Such Covenant Defeasance shall not cause the Trustee with respect to
the Securities of that series to have a conflicting interest as defined in
Section 6.08 and for purposes of the Trust Indenture Act with respect to the
Securities of any series;

     (c) Such Covenant Defeasance will not result in a breach or violation of,
or constitute a default under, this Indenture or any other agreement or
instrument to which the Company is a party or by which it is bound;

     (d) Such Defeasance would not cause any Outstanding Security of such
series then listed on any nationally recognized securities exchange to be then
delisted as a result thereof;

     (e) No Event of Default or event which with notice or lapse of time would
become an Event of Default with respect to Securities of that series shall have
occurred and be continuing on the date of such deposit or during the period
ending on the 91st day after such date;

     (f) The Company has delivered to the Trustee an Opinion of Counsel stating
that (i) Holders of the Securities of such series will not recognize income,
gain or loss for Federal income tax purposes as a result of such deposit and

                                       70
<PAGE>

Covenant Defeasance and will be subject to Federal income tax on the same
amount and in the same manner and at the same times, as would have been the
case if such deposit and Covenant Defeasance had not occurred; (ii) such
Covenant Defeasance would not cause any outstanding Security of such series
then listed on any nationally recognized securities exchange to be delisted as
a result thereof; and (iii) such deposit would not result in the trust arising
from such deposit constituting an investment company within the meaning of the
Investment Company Act of 1940, as amended from time to time;

     (g) The Company has delivered to the Trustee an Opinion of Counsel to the
effect that after the 91st day following the deposit, the trust funds will not
be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally, except
that if a court were to rule under any such law in any case or proceeding that
the trust funds remained property of the Company, no opinion is given as to the
effect of such laws on the trust funds except the following: (A) assuming such

     SECTION 11.01. Applicability of Article

     Any Securities that are redeemable before their Stated Maturity shall be

contemplated by Section 3.01 for any 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. In case of any redemption at the election of the Company of
less than all the Securities of any series, 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 tenor, if applicable, of the Securities to be redeemed, and of the
principal amount of 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 of the Securities of a specified tenor are to be redeemed), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of 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
portions (equal to the minimum authorized denomination for Securities of that
series or any multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of that series. If less than all of the Securities of such series
and of a specified tenor are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 45 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 and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.

                                       72
<PAGE>

     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 this address appearing in the
Security Register.

     All notices of redemption shall state:

     (a) the Redemption Date,

     (b) the Redemption Price,

     (c) if less than all the Outstanding Securities of any series are to be
redeemed, the identification (and, in the case of partial redemption, the
principal amounts) of the particular Securities to be redeemed,

     (d) 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,

     (e) the place or places where such Securities are to be surrendered for
payment of the Redemption Price, and

     (f) that the redemption is for a sinking fund, if such is the case.

     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.
The notice of redemption mailed in the manner herein provided shall be
conclusively presumed to have been duly given whether or not the Holder
receives such notice. In any case, failure to give such notice by mail or any
defect in the notice to the Holder of any Security shall not affect the
validity of the proceeding for the redemption of any other Security.

<PAGE>

     SECTION 11.05. Deposit of Redemption Price

     Prior to 10:00 a.m., New York City time, on 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 accrued interest on, all the Securities which are to be redeemed
on that date.

     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 installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall 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 premium, if any) 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 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. If a Security in permanent global
form is so surrendered, the Company shall execute, and the Trustee shall
authenticate and deliver to the Depositary for such Security in permanent
global form, without service charge to the Holder, a new Security in permanent
global form in a denomination equal to

                                       74

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

     The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." If provided for by the terms of Securities of any series, 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 of any series as provided for by the terms of Securities of such
series.

     SECTION 12.02. Satisfaction of Sinking Fund Payments with Securities

     The Company (a) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (b) 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 the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
Series; 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 to be so 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 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of such Securities, the 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 of that
series pursuant to Section 12.02 stating that such Securities have not been
previously used as a credit against any sinking fund payment and will also
deliver to the Trustee any Securities to be so delivered. Not less than 30 days
before 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
11.05, 11.06 and 11.07.
