SECTION 1.03. Compliance Certificates and Opinions

     Upon any application or request by the Company to the Trustee to take any
action under any provision of this Indenture, the Company shall furnish to the
Trustee an Officers' Certificate stating that all conditions precedent, if any,
provided for in this Indenture relating to the proposed action have been

SECTION 1.04. Form of Documents Delivered to Trustee

     In any case where several matters under the Indenture or the Guarantee
Agreement are required to be certified by, or covered by an opinion of, any
specified Person, it is not necessary that all such matters be certified by, or
covered by the opinion of, only one such Person, or that they be so certified or
covered by only one document, but one such Person may certify or give an opinion
with respect to some matters and one or more other such Persons as to other

in one or several documents.

     Any certificate or opinion of an officer of the Company or the Guarantor in
connection with the Indenture or the Guarantee Agreement may be based, insofar
as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are

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

matters are erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 1.05. Acts of Holders

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture or the Guarantee Agreement to be
given or taken by Holders of the outstanding Securities of all series or one or
more series, as the case may be, 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, and where it is expressly required by the Guarantee Agreement, to the
Guarantor. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holder
or 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 the Guarantee Agreement and (subject to
Section 6.01) conclusive in favor of the Trustee and the Company or the

<PAGE>
                                      -9-


Guarantor, as the case may be, if made in the manner provided in this Section
1.05. The Company may set a record date for purposes of determining the identity
of Holders entitled to vote or consent to any action by vote or consent
authorized or permitted under this Indenture or the Guarantee Agreement, which
record date shall be not earlier than 30 days prior to the first solicitation of
such vote or consent. If a record date is fixed, those persons who were Holders
of Securities at such record date (or their duly designated proxies), and only
those persons, shall be entitled to take such action by vote or consent or to
revoke any vote or consent previously given, whether or not such persons
continue to be Holders after such record date. No such vote or consent shall be
valid or effective for more than 120 days after such record date.

     (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 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 Securities 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, the Company or the
Guarantor in reliance thereon, whether or not notation of such action is made
upon such Security.

SECTION 1.06. 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: Citibank
     Agency and Trust Services 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 the address of its principal office specified in the
     first paragraph of this Indenture or at any other address previously
     furnished in writing to the Trustee by the Company, Attention: Vice
     President and Assistant Treasurer.

SECTION 1.07. Notices 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 Securities 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 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 notice as required by this
Indenture, then such method of notification as shall be made with the approval
of the Trustee shall constitute a sufficient notice.

SECTION 1.08. 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. If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

SECTION 1.09. 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 1.10. 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 1.11. 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 1.12. Benefits of Indenture

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

SECTION 1.13. Governing Law

     This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York.

SECTION 1.14. Legal Holidays

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of interest on
or principal (and premium, if any) of such Security need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date, Redemption Date or at the
Stated Maturity; and if so made, no interest shall accrue for the period from
and after such Interest Payment Date, Redemption Date or Stated Maturity, as the
case may be.

all action, including the execution and filing of any and all such documents and
instruments as may be necessary to continue such designation and appointment of
the Process Agent in full force and effect so long as this Agreement shall be in

address of the person entitled thereto as such address shall appear on the
Securities Register.

SECTION 3.02. Denominations

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

SECTION 3.03. Execution, Authentication, Delivery and Dating

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President, a Vice Chairman or one of its Vice Presidents,
under its corporate seal reproduced thereon attested by its 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 a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise. If not all the Securities of any
series are to be


<PAGE>
                                      -16-


issued at one time and if the Board Resolution or supplemental indenture
establishing such series shall so permit, such Company Order may set forth
procedures acceptable to the Trustee for the issuance of such Securities and the
determination of the terms of particular Securities of such series such as
interest rate, Stated Maturity, date of issuance and date from which interest
shall accrue. In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating:

          (a) that the form or forms and terms of such Securities have been
     established in conformity with the provisions of this Indenture and

          (b) that such Securities, when completed by appropriate insertions and
     executed by the Company and delivered to the Trustee for authentication in
     accordance with this Indenture, authenticated and delivered by the Trustee
     in accordance with this Indenture and issued by the Company in the manner
     and subject to any conditions specified in such Opinion of Counsel, will
     constitute the legal, valid and binding obligations of the Company.

     If not all the Securities of any series are to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel at the time of issuance
of each Security, but such opinion with appropriate modifications shall be
delivered at or before the time of issuance of the first Security of such
series. The Trustee shall not be required to authenticate Securities if the
issuance of such Securities pursuant to this Indenture will affect the Trustee's
own rights, duties or immunities under the Securities and this Indenture or
otherwise in a manner which is not reasonably acceptable to the Trustee.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

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, 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 each such series to be prepared without unreasonable
delay. After the preparation of definitive Securities of any series, the
temporary Securities of each such series shall be exchangeable for


<PAGE>
                                      -17-


definitive Securities upon surrender of the temporary Securities of such series
at any office or agency of the Company designated pursuant to Section 10.02,
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 authorized denominations of the same series. 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 designated pursuant to Section 10.02 being herein sometimes
collectively referred to as the "Securities Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Securities Registrar" for the purposes of registration and transfer
of Securities as herein provided.

     Upon surrender for registration of transfer of any Securities of a series
at an office or agency of the Company designated pursuant to Section 10.02 for
such purpose, 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, of a like
aggregate principal amount.

     At the option of the Holder, Securities of a series may be exchanged for
other Securities of the same series, of any authorized denominations, of a like
aggregate principal amount, upon surrender of the Securities of such series to
be exchanged at such office or agency, and upon payment, if the Company shall so
require, of the charges hereinafter provided. 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
exchange shall (if so required by the Company or the Securities Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Securities 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 or 9.06 not involving any transfer.


<PAGE>
                                      -18-


     The Company shall not be required to (i) 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 selection for redemption of Securities of
that series under Section 11.03 and ending at the close of business on the day
of the mailing of notice of redemption or (ii) 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.

     Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected only through a book entry system maintained by the Holder of
such Global Security (or its agent), and that ownership of a beneficial interest
in the Security shall be required to be reflected in a book entry.

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 like series, 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 upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of like series, 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 3.06, 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 issued pursuant to this Section 3.06 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 duly issued hereunder.

     The provisions of this Section 3.06 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

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date or within five days thereafter shall
be paid to the Person in whose name such Security (or one or more Predecessor
Securities) is registered at the close of business on the Record Date for such
interest; provided, however, that each installment of interest on any Security
may at the Company's option be paid by mailing a check for such interest,
payable to or upon the written order of the Person entitled thereto pursuant to
Section 3.08, to the address of such Person as it appears on the Securities
Register.

     Any interest on any Security which is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date or within five days
thereafter (herein called "Defaulted Interest") shall forthwith cease to be
payable to the registered Holder on the relevant Record Date; and, except as
hereinafter provided, such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities (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 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 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 at his address as it appears in the Securities Register not
     less than 10 days prior to such Special Record Date. The Trustee may, in
     its discretion, in the name and at the expense of the Company, cause a
     similar notice to be published at least once in an Authorized Newspaper in
     the Borough of Manhattan, The City of New York, but such publication shall
     not be a condition precedent to the establishment of such Special Record
     Date. Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been mailed as aforesaid, such
     Defaulted Interest shall be paid to the Persons in whose names the
     Securities (or their respective Predecessor Securities), are registered on
     such Special Record Date and shall no longer be payable pursuant to the
     following Clause (2).

          (2) The Company may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities


<PAGE>
                                      -20-


     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 payment
     shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section 3.07, each Security
delivered under this Indenture upon 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 shall 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, on)
and (subject to Section 3.07) interest, if any, on such Security and for all
other purposes whatsoever, whether or not such Security be overdue, and neither
the Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 3.09. Cancellation

     All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section 3.09,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of by the Trustee in its customary manner.

SECTION 3.10. Computation of Interest

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

SECTION 3.11. Interest Act (Canada)

     For the purposes only of the disclosure required by the Interest Act
(Canada), and without affecting the amount of interest payable to any Holder or
the calculation of interest on any Securities, if any rate of interest on any
Securities is calculated on the basis of a year (the "deemed year") which
contains fewer days than the actual number of days in the calendar year of
calculation, such rate of interest shall be expressed as a yearly rate for the
purposes of the Interest Act (Canada) by multiplying such rate of interest by
the actual number of days in the calendar year of calculation and dividing it by
the number of days in the deemed year.

SECTION 3.12. CUSIP Numbers

     The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of
redemption as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any
change in the CUSIP numbers.

SECTION 3.13. Book-Entry Provisions for Global Security.

     (a) Any Global Security of a series initially shall (i) be registered in
the name of the depository who shall be The Depository Trust Company or as
otherwise identified in the Board Resolution authorizing the issuance of such
series of Securities (the "Depository") or the nominee of such Depository, (ii)
be delivered to the Trustee as custodian for such Depository and (iii) bear any
required legends.

     Members of, or participants in, the Depository ("Agent Members") shall have
no rights under this Indenture with respect to any Global Security held on their
behalf by the Depository, or the Trustee as its custodian, or under the Global
Security, and the Depository may be treated by the Company, the Trustee and any
agent of the Company or the Trustee as the absolute owner of the Global Security
for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company, the Trustee or any agent of the Company or the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depository or impair, as between the Depository and its Agent
Members, the operation of customary practices governing the exercise of the
rights of a Holder of any Security.

     (b) Transfers of any Global Security shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Security may be
transferred or exchanged for definitive Securities in accordance with the rules
and procedures of the Depository. In addition, definitive Securities shall be
transferred to all beneficial owners in exchange for their beneficial interests
in a Global Security if (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository for the Global Security and a
successor depository is not appointed by the Company within 90 days of such
notice or (ii) an Event of Default has occurred and is continuing.

     (c) In connection with any transfer or exchange of a portion of the
beneficial interest in any Global Security to beneficial owners pursuant to
paragraph (b), the Securities Registrar shall (if one or more definitive
Securities are to be issued) reflect on the Securities Register the date and a
decrease in the principal amount of the Global Security in an amount equal to
the principal amount of the beneficial interest in the Global Security to be
transferred, and the Company and the Guarantor shall execute, and the Trustee
shall authenticate and deliver, one or more definitive Securities of like tenor
and amount.


<PAGE>
                                      -22-


     (d) In connection with the transfer of an entire Global Security to
beneficial owners pursuant to paragraph (b), the Global Security shall be deemed
to be surrendered to the Trustee for cancellation, and the Company and the
Guarantor shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depository in exchange for its beneficial
interest in the Global Security, an equal aggregate principal amount of
definitive Securities of authorized denominations.

     (e) The Holder of any Global Security may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Securities of such series.


                                  ARTICLE FOUR

                  SATISFACTION AND DISCHARGE: UNCLAIMED MONEYS


SECTION 4.01. Satisfaction and Discharge of Indenture

     (A) If at any time

          (a) the Company shall have paid or caused to be paid the principal of
     and interest on all the Securities of any series outstanding hereunder, as
     and when the same shall have become due and payable, or

          (b) the Company shall have delivered to the Trustee for cancellation
     all Securities of any series theretofore authenticated (other than any
     Securities which shall have been destroyed, lost or stolen and which shall
     have been replaced or paid as provided in Section 3.06), or

          (c) (i) all the Securities of such series not theretofore delivered to
     the Trustee for cancellation shall have become due and payable, are by
     their terms to become due and payable within one year or are to be called
     for redemption within one year under arrangements satisfactory to the
     Trustee for the giving of notice of redemption; and (ii) the Company shall
     have irrevocably deposited or caused to be irrevocably deposited with the
     Trustee (or an escrow agent satisfactory to the Trustee) as trust funds the
     entire amount in cash (other than moneys repaid by the Trustee or any
     paying agent to the Company in accordance with Section 4.04) or direct
     noncallable obligations of, or noncallable obligations guaranteed by, the
     United States of America or an agency thereof for the payment of which
     guarantee or obligation the full faith and credit of the United States is
     pledged ("U.S. Government Obligations"), maturing as to principal and
     interest in such amounts and at such times without consideration of any
     reinvestment of such principal and interest as will ensure the availability
     of cash, or a combination of U.S. Government Obligations and cash,
     sufficient to pay at Stated Maturity all the Securities of such series not
     theretofore delivered to the Trustee for cancellation, in-


<PAGE>
                                      -23-


     cluding principal (and premium, if any) and interest due or to become due
     to such date of Stated Maturity or Redemption Date, as the case may be, and
     if, in any such case, the Company shall also pay or cause to be paid all
     other sums payable hereunder by the Company with respect to Securities of
     such series, then this Indenture, the Guarantee Agreement and the Guarantee
     shall cease to be of further effect with respect to Securities of such
     series (except as to (i) rights of registration of transfer and exchange,
     (ii) substitution of apparently mutilated, defaced, destroyed, lost or
     stolen Securities, (iii) rights of Holders to receive payments of principal
     thereof and interest thereon, upon the original stated due dates therefor
     or Redemption Date (but not upon acceleration), (iv) the rights,
     obligations and immunities of the Trustee hereunder, and (v) the rights of
     the Holders of Securities of such series as beneficiaries hereof with
     respect to the property so deposited with the Trustee payable to all or any
     of them), and the Trustee, on demand of the Company accompanied by (i) an
     Officers' Certificate and an Opinion of Counsel, each stating that all
     conditions precedent herein provided relating to the satisfaction and
     discharge of this Indenture, the Guarantee Agreement and the Guarantee with
     respect to Securities of such series have been complied with and at the
     cost and expense of the Company, and (ii) an opinion of independent legal
     counsel (a) stating that (1) the Company has received from, or there has
     been published by, the Internal Revenue Service a ruling, or (2) since the
     date of this Indenture there has been a change in the applicable U.S.
     federal income tax law, in either case to the effect that, and based
     thereon such opinion of independent legal counsel shall confirm that, the
     Holders of the Securities will not recognize income, gain or loss for U.S.
     federal income tax purposes as a result of such deposit and discharge and
     will be subject to U.S. 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 defeasance had not occurred and (b) stating that Holders of the
     Securities will not recognize income, gain or loss for Canadian income tax
     purposes as a result of such deposit and discharge and will be subject to
     Canadian 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 defeasance had
     not occurred, shall execute proper instruments acknowledging such
     satisfaction of and discharging of this Indenture, the Guarantee Agreement
     and the Guarantee with respect to Securities of such series.

The Company agrees to reimburse the Trustee for any costs or expenses thereafter
reasonably and properly incurred and to compensate the Trustee for any services
thereafter reasonably and properly rendered by the Trustee in connection with
this Indenture or the Securities of such series.

     Notwithstanding the foregoing provisions of this Section 4.01(A), the
Company's obligations in Section 6.07 shall survive such satisfaction and
discharge.

     (B) In addition to the provisions of the next preceding paragraph, the
Company may terminate its obligations under the Securities of any series and
this Indenture and the Guarantor may terminate its obligations under the
Guarantee and the Guarantee Agreement, except those obligations referred to in
the penultimate paragraph of this Section 4.01, if all Securities of such series
previously authenticated and delivered (other than destroyed, lost or stolen
Securities of such series which have been replaced or paid or Securities of such
series for whose payment money or securities have there-


<PAGE>
                                      -24-


tofore been held in trust and thereafter repaid to the Company, as provided in
Section 4.04) have been delivered to the Trustee for cancellation and the
Company has paid all sums payable by it hereunder, or if the Company has
irrevocably deposited or caused to be deposited with the Trustee (or an escrow
agent satisfactory to the Trustee), under the terms of an irrevocable trust
agreement in form and substance satisfactory to the Trustee, as trust funds in
trust solely for the benefit of the Holders for that purpose, (i) money or (ii)
U.S. Government Obligations, or a combination thereof, maturing as to principal
and interest in such amounts and at such times as are sufficient without
consideration of any reinvestment of such principal or interest, to pay
principal of and interest on the outstanding Securities of such series to
maturity; provided that the Trustee shall have been irrevocably instructed to
apply such money or the proceeds of such U.S. Government Obligations to the
payment of said principal of and interest with respect to the outstanding
Securities of such series.

     Such irrevocable trust agreement shall include, among other things,
provision for (1) payment of the principal of and interest on the Securities of
such series, when due, (2) payment of the fees and expenses of the Trustee, its
agents and counsel incurred or to be incurred in connection with carrying out
such trust provisions, (3) rights of registration, transfer, substitution and
exchange of Securities of such series in accordance with the terms stated in
this Indenture, and (4) continuation of the rights and obligations and
immunities of the Trustee as against the Holders as stated in this Indenture.

     Notwithstanding the first paragraph of this Section 4.01(B), the Company's
obligations in Sections 3.05, 3.06, 4.04, 4.05, 5.02, 6.07, 6.10, 10.01 and
10.02 shall survive until the Securities of such series are no longer
outstanding; provided, however, that the Company's obligations in Section 5.02
shall survive only with respect to an Event of Default defined in Section
5.01(2) or 5.01(3). Thereafter the Company's obligations in Sections 4.04, 4.05
and 6.07 shall survive.

     After any such irrevocable deposit, accompanied by an Officers' Certificate
which shall state that the provisions of the first two paragraphs of this
Section 4.01(B) have been complied with, and upon delivery by the Company to the
Trustee of (a) an opinion of independent legal counsel who shall be acceptable
to the Trustee, or, in lieu thereof, a favorable determination by the Internal
Revenue Service to the effect that Holders of the Securities of such series will
not recognize income, gain or loss for U.S. federal income tax purposes as a
result of such deposit and discharge and will be subject to U.S. federal income
tax on the same amount and in the same manner and at the same time as would have
been the case if such deposit and discharge had not occurred and (b) an opinion
of independent legal counsel stating that Holders of the Securities will not
recognize income, gain or loss for Canadian income tax purposes as a result of
such deposit and discharge and will be subject to Canadian 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 defeasance had not occurred, then the Company shall be
discharged of its obligations under the Securities of such series and this
Indenture with respect to such series of Securities except for those surviving
obligations specified above, and the Trustee upon request shall acknowledge in
writing such discharge. Prior to the delivery of such acknowledgment, the
Trustee may require the Company to deliver to it an Officers' Certificate and
Opinion of Counsel, each stating that all conditions precedent provided for

provision have been complied with, and the Opinion of Counsel shall also state
that such deposit does not violate applicable law.

SECTION 4.02. Deposited Moneys To Be Held in Trust by Trustee

     All moneys deposited with the Trustee pursuant to Section 4.01 shall be
held in trust and applied by it to the payment, either directly or through any
paying agent (including the Company if acting as its own paying agent), to the
Holders of the particular Securities of such series for the payment of which
such moneys have been deposited with the Trustee of all sums due and to become
due thereon for principal and interest.

SECTION 4.03. Paying Agent To Repay Moneys Held

     Upon the satisfaction and discharge of this Indenture with respect to
Securities of any series, all moneys then hold by any paying agent of the
Securities of such series (other than the Trustee) shall, upon demand of the
Company, be repaid to it or paid to the Trustee, and thereupon such paying agent
shall be released from all further liability with respect to such moneys.

SECTION 4.04. Return of Unclaimed Moneys

     Any moneys deposited with or paid to the Trustee for payment of the
principal of or interest on Securities and not applied but remaining unclaimed
by the Holders of Securities of any series for two years after the date upon
which the principal of or interest on such Securities, as the case may be, shall
have become due and payable, shall be repaid to the Company by the Trustee on
written demand and all liability of the Trustee shall thereupon cease; and the
Holder of any of the Securities of any series shall thereafter look only to the
Company for any payment which such Holder may be entitled to collect.

SECTION 4.05. Reinstatement

     If the Trustee is unable to apply any money or U.S. Government Obligations
in accordance with Section 4.01 with respect to Securities of any series by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company's obligations under this Indenture with respect to
the Securities of such series shall be revived and reinstated an though no
deposit had occurred pursuant to Section 4.01 until such time as the Trustee is
permitted to apply all such money or U.S. Government Obligations in accordance
with Section 4.01; provided, however, that if the Company has made any payment
of interest on or principal of any Securities of such series because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or U.S.
Government Obligations held by the Trustee.

     it to the filing of such petition or to the appointment of or taking of
     possession by a receiver, liquidator, assignee, trustee, sequestrator,
     custodian or similar official of the Company or the Guarantor or of any

     (other than in accordance with the terms of the Guarantee) or the Guarantor
     denies or disaffirms its obligation under the Guarantee; or

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

SECTION 5.02. Acceleration of Maturity; Rescission and Annulment

     If an Event of Default described in Section 5.01(l), (2), (3) (if the Event
of Default under clause (3) is with respect to less than all series of
Securities then Outstanding) or (7) above occurs and is continuing, then and in
every such case the Trustee or the Holders of not less than 25% in principal
amount of the Securities of such series then Outstanding (each such series
voting as a separate class) may declare the principal of all the Securities of
such series to be due and payable immediately, by a notice in writing to the
Company and the Guarantor (and to the Trustee if given by Holders), and upon any
such declaration such principal shall become and shall be immediately due and
payable, anything in this Indenture or in the Security or in the Guarantee or in
the Guarantee Agreement contained to the contrary notwithstanding. Upon payment
of such amount, all obligations of the Company in respect of the payment of
principal of the Securities of such series, and of the Guarantor under the
Guarantee of such series, shall terminate. If an Event of Default described in
Section 5.01(3) (if the Event of Default under clause (3) is with respect to all
series of Securities then Outstanding), Section 5.01(4) or (5) above occurs and
is continuing, then and in every such case, unless the principal of all the
Securities shall have already become due and payable, the Trustee or the Holders
of not less than 25% in principal amount of all the Securities then Outstanding
(treated as one class) which have not previously become due and payable may
declare the entire principal of all the Securities then Outstanding to be due
and payable immediately, by notice in writing to the Company and the Guarantor
(and to the Trustee if given by Holders) and upon any such declaration such
principal shall become and shall be immediately due and payable, anything in
this Indenture or in the Securities or in the Guarantee or in the Guarantee
Agreement contained to the contrary notwithstanding. Upon payment of such
amount, all obligations of the Company in respect of the payment of principal of
the Securities and of the Guarantor in respect of its Guarantee shall terminate.

     At any time after such a declaration of acceleration 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 each series so affected, by
written notice to the Company, the Guarantor and the Trustee, may rescind and
annul such declaration and its consequences if


<PAGE>
                                      -28-


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

               (A) all overdue installments of interest on the Securities of
          such series, and

               (B) the principal of (and premium, if any, on) with respect to
          any Securities of such series which have become due otherwise than by
          such declaration of acceleration, with interest thereon from the date
          such principal became due at the rate borne by the Securities of such
          series, and

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue installments of interest at the rate borne by
          the Securities of such series, and

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

          (2) all Events of Default, other than the nonpayment of the principal
     of Securities of such 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.

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

     The Company covenants that if default is made in the payment of (1) any
installment of interest on any Security of any series when such interest becomes
due and payable and such default continues for a period of 30 days or (2) the
principal of (and premium, if any, on) any Security of any series at the
Maturity thereof or otherwise, the Company will, upon demand of the Trustee, pay
to the Trustee, for the benefit of the Holders of such Securities of each series
so affected, the whole amount then due and payable on such Securities of such
series for principal (and premium, if any) or interest, if any, or both, as the
case may be, with interest upon the overdue principal and, to the extent that
payment of such interest shall be legally enforceable, upon overdue installments
of interest, at the rate per annum borne by the Securities during the period of
such default; 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.

     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, the Guarantor or any other obligor upon the Securities of
each series so affected and collect the moneys adjudged or decreed to be payable
in the manner provided by law out of the property of the Company, the Guarantor
or any other obligor upon the Securities of each series so affected, wherever
situated.


<PAGE>
                                      -29-


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

SECTION 5.04. Trustee May File Proofs of Claim

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company, the Guarantor or any other obligor
upon the Securities or the property of the Company, the Guarantor or of such
other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities of each series so affected 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 or the Guarantor
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 amount of principal (and
     premium, if any) and interest, if any, owing and unpaid in respect of the
     Securities of each series so affected 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 receiver, assignee, trustee, liquidator, sequestrator, custodian 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,
the Guarantee or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 5.05. Trustee May Enforce Claims Without Possession of Securities

     All rights of action and claims under this Indenture, the Securities, the
Guarantee Agreement or the Guarantee 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


<PAGE>
                                      -30-


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.

SECTION 5.06. Application of Money Collected

     Any money collected by the Trustee pursuant to this Article Five 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 an account of principal (and premium,
if any) or interest, if any, 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 Section
     6.07;

          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any, on) and interest, if any, on the
     Securities of the series 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, if any, respectively; and

          THIRD: The balance, if any, to the Company.

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 the
Guarantee Agreement, 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 each series affected (with each series voting as
     a separate class) 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 indemnity
     reasonably satisfactory to it 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


<PAGE>
                                      -31-


          (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 the Outstanding Securities of each series affected
     (with each series voting as a separate class);

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

SECTION 5.08. Unconditional Right of Holders To Receive Principal and Interest

     Notwithstanding any other provision in this Indenture or the Guarantee
Agreement, 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,
on) and (subject to Section 3.07) interest, if any, on such Security on or after
the Stated Maturity expressed in such Security (or, in the case of redemption,
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 or the Guarantee Agreement 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
Guarantor, 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

     No right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 5.11. Delay or Omission Not Waiver

     No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given


<PAGE>
                                      -32-


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 each series affected (each series voting as a separate class) 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 or Guarantee of such series;
provided that

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

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

SECTION 5.13. Waiver of Past Defaults

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

          (a) in the payment of the principal of (and premium, if any, on) or
     interest, if any, on any Security or

          (b) in respect of a covenant or provision hereof which under Article
     Nine 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 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 and
expenses, 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 5.14 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any


<PAGE>
                                      -33-


Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of each series affected, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of
(or premium, if any, on) or interest, if any, on any Security of such series on
or after the Stated Maturity expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).


                                   ARTICLE SIX

                                   THE TRUSTEE


SECTION 6.01. Certain Duties and Responsibilities

     (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to Securities of such series,

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

          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture or the
     Guarantee Agreement; 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
     or the Guarantee Agreement, as the case may be (but need not confirm or
     investigate the accuracy of any mathematical calculations or other facts
     stated therein).

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

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

          (1) this paragraph (c) shall not be construed to limit the effect of
     paragraph (a) of this Section 6.01;


<PAGE>
                                      -34-


          (2) 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; and

          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it with respect to the Securities of any series
     in good faith in accordance with the direction of the Holders of a majority
     in principal amount of the Outstanding Securities of such series 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 or the Guarantee Agreement.

     No provision of this Indenture or the Guarantee Agreement 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.

SECTION 6.02. Notice of Defaults

     Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit by mail to all
Holders of such series entitled to receive reports pursuant to Section 7.04,
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 (and premium, if any) or interest, if
any, on any Security 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; and provided, further, that in the case of any default
of the character specified in Section 5.01(3) 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 6.02, 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

     Except as otherwise provided in Section 6.01:

          (a) the Trustee may conclusively rely and shall be fully protected in
     acting or refraining from acting upon any resolution, certificate,
     statement, instrument, opinion, report, notice, request, direction,
     consent, order, bond, debenture, note or other paper or document (whether
     in its original or facsimile form) believed by it to be genuine and to have
     been signed or presented by the proper party or parties;

SECTION 6.08. Disqualification; Conflicting Interests

     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 either eliminate such conflicting interest or resign with respect to
the Securities of such series, to the extent and in the manner provided by, and
subject to the provisions of, the Trust Indenture Act and this Indenture.

     The following Indentures between the Guarantor and the Trustee shall be

SECTION 6.09. Corporate Trustee Required; Eligibility

     There shall at all times be a Trustee hereunder with respect to each series
of Securities which shall be a Person eligible under the Trust Indenture Act,
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by U.S. Federal or State authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of said supervising or examining authority, then for the
purposes of this Section 6.09, 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. No obligor of the
Securities or Person directly or indirectly controlling, controlled by or under
common control with such obligor or the Guarantor shall serve as Trustee upon
such Securities. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.09, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article Six.

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 Six shall become effective until the
acceptance of appointment by the successor Trustee under 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 an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition at the expense of the Company any court of
competent jurisdiction for the appointment of a successor Trustee.

     (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company. If an instrument of acceptance by a successor


<PAGE>
                                      -38-


Trustee shall not have been delivered to the Trustee within 30 days after the
receipt of such notice of removal, the removed Trustee may petition at the
expense of the Company any court of competent jurisdiction for the appointment
of a successor Trustee.

     (d) If at any time with respect to any series of Securities:

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

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

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation, then, in any such case, (i)
     the Company by a Board Resolution may remove the Trustee with respect to
     such series of Securities or (ii) subject to Section 5.14, any Holder who
     has been a bona fide Holder of a Security for at least six months may, on
     behalf of himself and all others similarly situated, petition any court of
     competent jurisdiction for the removal of the Trustee and the appointment
     of a successor Trustee.

     (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). 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 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 shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee by mailing written
notice of such event by first-class mail, postage prepaid, to the Holders of the
Securities of one or more or all series, as the case may be, to which the
resignation, removal or appointment relates, as their names and addresses ap-


<PAGE>
                                      -39-


pear in the Securities Register. Each notice shall include the name of the
successor Trustee 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 request of
the Company or the successor Trustee, such retiring Trustee shall, upon payment
of its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder, subject, nevertheless to its lien, if
any, provided for in Section 6.07.

     (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 (i) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (ii)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(iii) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and, upon the execution and delivery of such
supplemental indenture, the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

     (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


<PAGE>
                                      -40-


such rights, powers and trusts referred to in paragraph (a) or (b) of this
Section 6.11, as the case may be.

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

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 Six,
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 Against Company

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

SECTION 6.14. Trustee's Application for Instructions from the Company

     Any application by the Trustee for written instructions from the Company
may, at the option of the Trustee, set forth in writing any action proposed to
be taken or omitted by the Trustee under this Indenture and the date on and/or
after which such action shall be taken or such omission shall be effective. The
Trustee shall not be liable for any action taken by, or omission of, the Trustee
in accordance with a proposal included in such application on or after the date
specified in such application (which date shall not be less than three Business
Days after the date any officer of the Company actually receives such
application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

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 Securities at the time Outstanding of all series affected by such
supplemental indenture (each such series voting as a separate 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 this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each outstanding Security
affected thereby,

          (1) change the Stated Maturity of the principal of (or premium, if
     any, on), or any installment of principal of or interest, if any, on, any
     Security, or reduce the principal amount thereof or the interest thereon,
     or change the place of payment where, or the coin or currency in which, any
     Security 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

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

          (3) modify any of the provisions of this Section 9.02 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.

     A supplemental indenture that changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or that 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 9.02 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 Nine or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled

stating that the execution of such supplemental indenture is authorized or
permitted by this

                                      -46-


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 Nine,

shall be bound thereby.

     Every supplemental indenture executed pursuant to this Article Nine shall
conform to the requirements of the Trust Indenture Act as then in effect.

SECTION 9.06. Reference in Securities to Supplemental Indentures

     Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article Nine 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 so modified as to conform, in the opinion of the Trustee and the
Board of Directors, 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.


                                   ARTICLE TEN

SECTION 10.01. Payment of Principal and Interest

     For the benefit of each series of Securities, the Company will duly and
punctually pay the principal of (and premium, if any) and interest, if any, on
the Securities of that series in accordance with the terms of such Securities
and this Indenture.

SECTION 10.02. Maintenance of Office or Agency

     The Company will maintain in the Borough of Manhattan, The City of New
York, an office or agency where Securities may be presented or surrendered for
payment, where Securities may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and de-


<PAGE>
                                      -47-


mands 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 (in or outside The City of New York) where the Securities may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in the Borough of Manhattan, The City of New York, for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

SECTION 10.03. Money for Security Payments To Be Held in Trust

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

     Whenever the Company shall have one or more Paying Agents, it will, on each
due date of the principal of (or premium, if any) or interest, if any, on any
Securities, deposit with a Paying Agent a sum sufficient to pay the principal or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal or interest, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

     The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section 10.3, that such
Paying Agent will:

          (a) hold all sums held by it for the payment of the principal of (or
     premium, if any) or interest, if any, on Securities in trust for the
     benefit of the Persons entitled thereto until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided;

          (b) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal of (or premium, if any, on) or interest, if any, on
     the Securities of that series when the same shall be due and payable; and

          (c) 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.

waive such compliance in such instance or generally waive compliance with such

<PAGE>
                                      -51-


covenant or condition, but no such waiver shall extend to or affect such

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES


SECTION 11.01. Applicability of Article

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified, as contemplated by Section 3.01 for Securities of any series) in
accordance with this Article Eleven; provided, however, that if any provision of
any such Security shall conflict with any provision of this Article Eleven, the
provision of such Security shall govern. Except as otherwise set forth in any
Security, each Security shall be subject to partial redemption only in the
amount of $1,000 or integral multiples thereof.

SECTION 11.02. Election to Redeem; Notice To Trustee

     The right of the Company to elect to redeem any Securities of any series
shall be set forth in the terms of such Securities of such series established in
accordance with Section 3.01. In case of any redemption at the election of the
Company, 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 and of the principal amount of
Securities of such series to be redeemed and shall deliver to the Trustee such
documentation and records as shall enable the Trustee to select the Securities
to be redeemed pursuant to Section 11.03. 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, 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 may be
specified by the terms of such Securities or, if no such method is so specified,
by


<PAGE>
                                      -52-


such method as the Trustee shall deem appropriate and which may provide for the
selection for redemption of portions of the principal amount of Securities of
such series.

     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.

     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 the Company or, at the Company's
request, by the Trustee to the Holders of the Securities to be redeemed, 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
such Holder's address appearing in the Securities Register.

     All notices of redemption shall state:

          (1) the Redemption Date;

          (2) the Redemption Price;

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

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

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

          (6) the applicable CUSIP Numbers.

SECTION 11.05. Deposit of Redemption Price

     On or before any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 10.03) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.


<PAGE>
                                      -53-


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 and at the place or places therein specified, and from and
after such date (unless the Company shall default in the payment of the
Redemption Price and accrued interest, if any) 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
therefor, the Redemption Price 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 that is to be redeemed only in part shall be surrendered at
the 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, 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.
