Security evidencing all or a portion of the same debt as that evidenced by such
particular Security; and, for the purposes of this definition, any Security

any, provided for in this Indenture relating to the proposed action have been

counsel all such conditions precedent, if any, have been complied with, except
that in the case of any such application or request as to which the furnishing
of such documents is specifically required by any provision of this Indenture
relating to such particular application or request, no additional certificate or
opinion need be furnished.

          Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

          (a) a statement that each individual signing such certificate or
opinion has read such condition or covenant and the definitions herein relating

investigation upon which the statements or opinions contained in such
certificate or opinion are based;

          (c) a statement that, in the opinion of each such individual, he has

an informed opinion as to whether or not such condition or covenant has been
complied with; and

          (d) a statement as to whether, in the opinion of each such individual,

          Section 1.3 Form of Documents Delivered to Trustee.

          In any case where several matters 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 matters, and any such Person may certify
or give an opinion as to such matters in one or several documents. Any
certificate or opinion of an officer of the Company 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

                                        7

<PAGE>

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
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company, unless such counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters are erroneous.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

          Any certificate, statement or opinion of an officer of the Company or
of counsel may be based insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by a firm of accountants or an
accountant in the employ of the Company, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

          Any certificate or opinion of any independent firm of public
accountants filed with the Trustee shall contain a statement that such firm is
independent.

          Section 1.4 Acts of Holders.

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing. 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. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 6.1) conclusive in favor of the Trustee and the Company and any agent of
the Trustee or the Company, if made in the manner provided in this Section.

          (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee may
determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.

          (c) The ownership of Securities and the principal amount and serial
numbers of Securities held by any Person, and the date of holding the same,
shall be proved by the Security Register.

          (d) If the Company shall solicit from the Holders of any Securities
any request, demand, authorization, direction, notice, consent, waiver or other
Act, the Company

                                        8

<PAGE>

may, at its option, by Board Resolution, fix in advance a record date for the
determination of Holders of Securities entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of Securities of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months
after the record date.

          (e) Any request, demand, authorization, direction, notice, consent,
waiver or other action by 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 or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent or the Company in reliance thereon, whether or not
notation of such action is made upon such Security.

          Section 1.5 Notices, Etc., to Trustee and Company.

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

          (a) the Trustee by any Holder or by the Company shall be sufficient
for every purpose hereunder if made, given, furnished or filed in writing to or
with the Trustee at its Corporate Trust Office, Attention: Corporate Trust
Administration Division, 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 the
attention of its Treasurer at the address of its principal office specified in
the first paragraph of this instrument or at any other address previously

          Section 1.6 Notice to Holders of Securities; Waiver.

          Except as otherwise expressly provided herein or in the form of
Securities of any particular series pursuant to the provisions of this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event, such notice shall be sufficiently given to Holders of Securities if
in writing and mailed, first-class postage prepaid, to each Holder of a Security
affected by such event, at his address as it appears in the Security Register,
not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice.

          In any case where notice to Holders of Securities is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder of a Security shall affect the sufficiency of such
notice with respect to other Holders of Securities. In

                                        9

the case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

          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 of Securities 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.

          Section 1.7 Language of Notices, Etc.

          Any request, demand, authorization, direction, notice, consent,
election or waiver required or permitted under this Indenture shall be in the

may be in an official language of the country of publication.

          Section 1.8 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 provisions shall
control.

          Section 1.9 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 shall be invalid, illegal or
unenforceable, the validity, legality or 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, any Security Registrar,
any Paying Agent, any Authenticating Agent and their successors hereunder and
the Holders of Securities, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

          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 at any Place of Payment,
then (notwithstanding any other provision of this Indenture or the Securities
other than a provision in the Securities which specifically states that such
provision shall apply in lieu of this Section) payment of interest or any
Additional Amounts or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, and no
interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be.

the delivery of the Company Order contemplated by Section 3.3 for the
authentication and delivery of such Securities.

execution of such Securities.

form, any such Security may provide that it shall represent the aggregate amount
of Outstanding Securities from time to time endorsed thereon and may also
provide that the aggregate amount of Outstanding Securities represented thereby
may from time to time be reduced to reflect exchanges or increased to reflect
the issuance of additional Securities. Any endorsement of a Security in global
form to reflect the amount, or any increase or decrease in the amount, of
Outstanding Securities represented thereby shall be made in such manner and by
such Person or Persons, as shall be specified therein or in the Company Order
delivered to the Trustee pursuant to Section 3.3.

                                    ARTICLE 3

on Registered Securities on any Interest Payment Date, whether and under what
circumstances Additional Amounts on such securities shall be payable in respect
of specified taxes, assessments or other governmental charges withheld or
deducted and, if so, whether the Company has the option to redeem the affected
Securities rather than pay such Additional Amounts, and the basis upon which
interest shall be calculated if other than that of a 360-day year of twelve
30-day months;

          (f) the place or places, if any, in addition to or other than the

          (k) if the amount of payments of principal of (and premium, if any) or

amounts shall be determined;

          (l) if the Securities of such series are to be issuable in definitive
form (whether upon original issue or upon exchange of a temporary Security of
such series) only upon

not be issued at the same time and, unless otherwise provided, a series may be
reopened for issuances of additional Securities of such series.

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

          Unless other denominations and amounts may from time to time be fixed
by or pursuant to a Board Resolution, the Registered Securities of each series,
if any, shall be issuable in registered form without coupons in denominations of
$1,000 and any integral multiple thereof.

          Section 3.3 Execution, Authentication, Delivery and Dating.

          The Securities shall be executed on behalf of the Company by its
Chairman of the Board, President, any Vice President or its Treasurer under its
corporate seal reproduced thereon and 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. The seal of the Company may be in the form of a
facsimile thereof and may be impressed, affixed, imprinted or otherwise
reproduced on the Securities. Typographical and other minor errors or defects in
any such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security that has been duly authenticated and
delivered by the Trustee.

          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.

                                       14

<PAGE>

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, executed by
the Company, to the Trustee for authentication, together with the Board
Resolution and Officers' Certificate or supplemental indenture with respect to
such Securities referred to in Section 3.1 and a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order and subject to the provisions hereof shall authenticate
and deliver such Securities. In authenticating such Securities, and accepting
the additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to Section
6.1) shall be fully protected in relying upon, an Opinion of Counsel stating,

          (a) that the form and terms of such Securities have been established
in conformity with the provision of this Indenture;

          (b) that all conditions precedent set forth in this Indenture to the
authentication and delivery of such Securities have been complied with and that
such Securities, when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute valid and legally binding obligations of the
Company, enforceable against the Company in accordance with their terms, subject
to bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization and
other laws of general applicability relating to or affecting the enforcement of
creditors' rights and to general equity principles; and

          (c) as to such other matters as the Trustee may reasonably request;

provided, however, that if all the Securities of any series are not 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 of Counsel, with appropriate
modifications, may instead be delivered at or prior to the time of the first
issuance of Securities of such series.

          The Trustee shall not be required to authenticate such Securities if
the issue of such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties or immunities under the Securities and this
Indenture or otherwise in a manner which is not reasonably acceptable to the
Trustee or if the Trustee, being advised by counsel, determines that such action
may not lawfully be taken.

          If the Company shall establish pursuant to Section 3.1 that Securities
of a series may be issued in whole or in part in global form, then the Company
shall execute and the Trustee shall, in accordance with this Section and the
Company Order with respect to such series, authenticate and deliver one or more
Securities in global from that (i) shall represent and shall be denominated in
an authorized aggregate amount equal to the aggregate principal amount of the
Outstanding Securities of such series and tenor to be represented by one or more
Securities in global form, (ii) shall be registered, in the name of the
Depositary for such Security or Securities in global form or the nominee of such
Depositary, (iii) shall be delivered to such Depositary or pursuant to such
Depositary's instruction and (iv) shall bear a legend substantially to the
following effect: "Unless and until it is exchanged in whole or in part for
Notes in certificated form, this Note may not be transferred except as a whole
by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the

                                       15

<PAGE>

Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary. Unless this certificate is presented by
an authorized representative of the Depository Trust Company (55 Water Street,
New York, New York) to the issuer or its agent for registration of transfer,
exchange or payment, and any certificate issued is registered in the name of
CEDE & CO. or such other name as requested by an authorized representative of
the Depository Trust Company and any payment is made to CEDE & CO., any
transfer, pledge or other use hereof for value or otherwise by or to any person
is wrongful since the registered owner hereof, CEDE & CO., has an interest
herein." Each Depositary designated pursuant to Section 3.1 for a Security in
global form must, at the time of its designation and at all times while it
serves as Depositary, be a clearing agency registered under the Securities
Exchange Act of 1934 and any other applicable statute or regulation.

          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 in Section
2.2 or 6.14 executed by or on behalf of the Trustee by the manual signature of
one of its authorized signatories, 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 3.4 Temporary Securities.

          Pending the preparation of definitive Securities of any series, the
Company may execute and deliver to the Trustee, and upon Company Order the
Trustee shall authenticate and deliver, in the manner provided in Section 3.3,
temporary Securities of such series 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, in registered form without coupons and with such appropriate
insertions, omissions, substitutions and other variations as the officers of the
Company executing such Securities may determine, as evidenced by their execution
of such Securities. In the case of Securities of any series, such temporary
Securities may be in global form, representing all of the Outstanding Securities
of such series and tenor.

          Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
of any series are issued, the Company will cause definitive Securities of that
series to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities of such series shall be
exchangeable upon request for definitive Securities of such series containing
identical terms and provisions upon surrender of the temporary Securities of
such series at an office or agency of the Company maintained for such purpose
pursuant to Section 10.2, 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 containing identical terms and provisions.
Unless otherwise specified as contemplated by Section 3.1 with respect to a
temporary Security in global form, until so

                                       16

<PAGE>

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 3.5 Registration, Transfer and Exchange.

          With respect to the Securities of each series, if any, the Company
shall cause to be kept, at an office or agency of the Company maintained
pursuant to Section 10.2, a register (herein sometimes referred to as the
"Security Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Securities of
each series and of transfers of the Securities of each series. The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers and exchanges of Securities as herein provided; provided that the
Company may, from time to time, designate (or change any designation of) any
other Person or Persons to act as Security Registrar or co-Security Registrars
with respect to the Securities of one or more series, with notice to the Trustee
and as provided in Section 1.6 to the Holders. At all reasonable times the
Security Register shall be open for inspection by the Company. In the event that
the Trustee shall not be the Security Registrar, it shall have the right to
examine the Security Register at all reasonable times.

          Upon surrender for registration of transfer of any Security of any
series at any office or agency of the Company maintained for that series
pursuant to Section 10.2, the Company shall execute, and the Trustee, at the
direction of the Company, shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series of an authorized denomination, of a like aggregate principal amount
bearing a number not contemporaneously outstanding and containing identical
terms and provisions.

          Notwithstanding any other provision of this Section, unless and until
it is exchanged in whole or in part for the individual Securities represented
thereby, in definitive form, a Security in global form representing all or a
portion of the Securities of a series may not be transferred except as a whole
by the Depositary for such series to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor Depositary
for such series or a nominee of such successor Depositary.

          At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series containing identical terms and
provisions, in any authorized denominations, and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at any such office or
agency of the Company maintained for that series pursuant to Section 10.2.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee, at the direction of the Company, shall authenticate
and deliver, the Securities which the Holder making the exchange is entitled to
receive.

          If at any time the Depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be eligible under Section 3.3, the Company, by
Company Order, shall appoint a successor Depositary with respect to the
Securities of such series. If a successor Depositary for the Securities of such
series is not appointed by the Company within 90 days after the Company receives
such notice or becomes

                                       17

<PAGE>

aware of such ineligibility, the Company's election pursuant to Section 3.1(c)
shall no longer be effective with respect to the Securities of such series and
the Company will execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of definitive Securities of such series, will
authenticate and deliver, Securities of such series in definitive form in an
aggregate principal amount and of like terms and tenor equal to the principal
amount of the Security or Securities in global form representing such series in
exchange for such Security or Securities in global form.

          The Company may at any time and in its sole discretion determine that
individual Securities of any series issued in global form shall no longer be
represented by such Security or Securities in global form. In such event the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of individual definitive Securities of such series
and of the same terms and tenor, will authenticate and deliver individual
Securities of such series in definitive form in authorized denominations and in
an aggregate principal amount equal to the principal amount of the Security or
Securities in global form representing such series in exchange for such Security
or Securities in global form.

          If specified by the Company pursuant to Section 3.1 with respect to a
series of Securities, the Depositary for such series of Securities may surrender
a Security in global form for such series of Securities in exchange in whole or
in part for individual Securities of such series in definitive form and of like
terms and tenor on such terms as are acceptable to the Company, the Trustee and
such Depositary. Thereupon, the Company shall execute, and the Trustee upon
receipt of a Company Order for the authentication and delivery of individual
definitive Securities of such series, shall authenticate and deliver, without
service charge:

          (a) to the Depositary or to each Person specified by such Depositary a
new individual Security or Securities of the same series and of the same tenor,
of authorized denominations, in aggregate principal amount equal to and in
exchange for such Person's beneficial interest in the Security in global form;
and

          (b) to such Depositary a new Security in global form in a denomination
equal to the difference, if any, between the principal amount of the surrendered
Security in global form and the aggregate principal amount of the individual
Securities delivered to Holders thereof.

          In any exchange provided for in any of the preceding three paragraphs,
the Company will execute and the Trustee pursuant to a Company Order will
authenticate and deliver individual Securities in definitive registered form in
authorized denominations.

          Upon the exchange of a Security in global form for Securities in
definitive form, at the direction of the Company, such Security in global form
shall be cancelled by the Trustee. Securities issued in exchange for a Security
in global form pursuant to this Section shall be registered in such names and in
such authorized denominations as the Depositary for such Security in global
form, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such
Securities to the persons in whose names such Securities are so registered or to
the Depositary.

                                       18

<PAGE>

          Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee, at the direction of the Company, shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

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

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

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.4, 9.6 or 11.7 not involving any transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange any 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 11.3 and ending at the close of business
on the day of such selection, or (ii) to register the transfer of or exchange
any Security so selected for redemption in whole or in part, except in the case
of any Security to be redeemed in part, the portion thereof not to be redeemed.

          Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee, at the direction of the Company, shall
authenticate and deliver in exchange therefor a new Security of the same series
containing identical terms and of like principal amount and bearing a number not
contemporaneously outstanding.

          If there be delivered to the Company and to 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 exchange for or in lieu of any such destroyed, lost
or stolen Security, a new Security of the same series containing identical terms
and of like 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.

                                       19
<PAGE>

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

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

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

          Section 3.7 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 shall, if so provided in such
Security, be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered as of the close of business on the Regular
Record Date for such interest.

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

          (a) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities affected (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 such 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 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company of such Special Record Date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor to be mailed, first
class postage prepaid, to each Holder of such Securities at his address as it
appears in the Security 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 a
newspaper,

                                       20

<PAGE>

customarily published in the English language on each Business Day and of
general circulation 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 such Securities
(or their respective Predecessor Securities) are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to
the following clause (b).

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

          Interest on Securities of any series that bear interest may be paid by
mailing a check to the address of the person entitled thereto as such address
shall appear in the Security Register.

          Subject to the foregoing provisions of this Section and Section 3.5,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

          Section 3.8 Persons Deemed Owners.

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any), and (subject to Sections 3.5 and 3.7) interest on and Additional Amounts
with respect to, 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.

          None of the Company, the Trustee, any Authenticating Agent, any Paying
Agent, the Security Registrar or any co-Security Registrar will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a Security in
global form or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests and each of them may act or refrain from
acting without liability on any information relating to such records provided by
the Depositary.

          Section 3.9 Cancellation.

          All Securities surrendered for payment, redemption, repayment,
registration of transfer or exchange or for credit against any sinking fund
payment, if surrendered to any Person other than the Trustee, shall be delivered
to the Trustee, and any such Securities and Securities surrendered directly to
the Trustee for any such purpose 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

                                       21

<PAGE>

whatsoever, and all Securities so delivered shall be promptly cancelled by the
Trustee at the direction of the Company. No securities shall be authenticated in
lieu of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be destroyed by it unless by a Company Order the Company
directs their return to it.

          Section 3.10 Computation of Interest.

          Except as otherwise contemplated by Section 3.1 for Securities of any
series, interest on the Securities of each series shall be computed on the basis
of a 360-day year of twelve 30-day months.

                                    ARTICLE 4

                           SATISFACTION AND DISCHARGE

          Section 4.1 Satisfaction and Discharge of Indenture.

          Upon the direction of the Company by a Company Order, this Indenture
shall cease to be of further effect (except as to any surviving rights of
registration of transfer or exchange of Securities herein expressly provided
for, rights, obligations, duties and immunities of the Trustee set forth in the
last paragraph of this Section and any right to receive Additional Amounts, as
provided in Section 10.4), and the Trustee, pursuant to a Company Order and at
the expense of the Company, shall execute proper instructions acknowledging
satisfaction and discharge of this Indenture, when

          (a) either

               (i) all Securities theretofore authenticated and delivered (other
     than (A) Securities which have been destroyed, lost or stolen and which
     have been replaced or paid as provided in Section 3.6, and (B) Securities
     for whose payment money has theretofore been deposited in trust or
     segregated and held in trust by the Company and thereafter repaid to the
     Company or discharged from such trust, as provided in Section 10.3) have
     been delivered to the Trustee for cancellation; or

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

                    (1) have become due and payable, or

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

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

                                       22

<PAGE>

and the Company, in the case of (1), (2) or (3) above, has irrevocably deposited
or caused to be deposited with the Trustee as trust funds in trust for the
purpose an amount sufficient to pay and discharge, or U.S. Government
Obligations, maturing as to principal and paying interest in such amounts and at
such times as will insure the availability of cash sufficient to pay and
discharge, the entire indebtedness on such Securities not theretofore delivered
to the Trustee for cancellation, for principal (and premium, if any) and
interest, and any Additional Amounts with respect thereto, to the date of such
deposit (in the case of Securities which have become due and payable) or to the
Stated Maturity or Redemption Date, as the case may be;

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

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

          In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so by Company Order with
respect to Securities of all series as to which it is Trustee and if the other
conditions thereto are met. In the event there are two or more Trustees
hereunder, then the effectiveness of any such instrument shall be conditioned
upon receipt of such instruments from all Trustees hereunder.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7 and, if money shall
have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

          Section 4.2 Application of Trust Money.

          Subject to the provisions of the last paragraph of Section 10.3, all
money deposited with the Trustee pursuant to Section 4.1 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and any interest and Additional Amounts for whose payment such money has
been deposited with the Trustee; but such money need not be segregated from
other funds except to the extent required by law.

                                    ARTICLE 5

                                    REMEDIES

          Section 5.1 Events of Default.

          "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law pursuant to any

                                       23

<PAGE>

judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

          (a) default in the payment of any interest on or any Additional
Amounts payable in respect of any of the Securities of such series as and when
such interest or Additional Amounts becomes due and payable, and continuance of
such default for a period of 30 days; or

          (b) default in the payment of all or any part of the principal of (and
premium, if any, on) any of the Securities of such series as and when the same
becomes due and payable at Maturity, or default in the deposit of any sinking
fund payment, when and as due by the terms of any of the Securities of such
series; or

          (c) default in the performance, or breach, of any covenant or
agreement of the Company in the Securities of such series or this Indenture
(other than a covenant or agreement a default in whose performance or whose
breach is elsewhere in this Section specifically dealt with), and continuance of
such default or breach for a period of 90 days after there has been given, by
registered or certified mail, return receipt requested, to the Company by the
Trustee or to the Company and the Trustee by the Holders of at least 25% in
principal amount of the Outstanding Securities to which covenant or agreement
relates a written notice specifying such default or breach and requiring it to
be remedied and stating that such notice is a "Notice of Default" hereunder; or

          (d) a court having jurisdiction in the premises shall enter a decree
or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable bankruptcy, insolvency, reorganization or other
similar law now or hereafter in effect, or appointing a receiver, liquidator,
assignee, custodian, trustee, sequestrator (or similar official) of the Company
or for any substantial part of its property, or ordering the winding-up or
liquidation of its affairs, and such decree or order shall remain unstayed and
in effect for a period of 90 consecutive days; or

          (e) the Company shall commence a voluntary case or other proceeding
seeking liquidation, reorganization or other relief with respect to itself or
its debts under any bankruptcy, insolvency, reorganization or other similar law
now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian, sequestrator or other similar official of it or any
substantial part of its property, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case
or other proceeding commenced against it, or shall make a general assignment for
the benefit of creditors, or shall fail generally to pay its debts as they
become due, or shall take any corporate action to authorize any of the
foregoing; or

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

          Section 5.2 Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default described in clause (a), (b) or (c) above (if
the Event of Default under clause (c) above is with respect to less than all
series of Securities then outstanding) occurs and is continuing, then, and in
each and every case, unless the principal of

                                       24

<PAGE>

all of the Securities of such series shall have already become due and payable,
either the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities of such series (each such series voting as
a separate class in the case of an Event of Default under clause (a) or (b) and
all such series voting as one class in the case of an Event of Default under
clause (c)), by notice in writing to the Company (and to the Trustee if given by
such Holders), may declare the entire principal of all Securities of such
series, or such lesser amount as may be provided for in the Securities of that
series, and the interest accrued thereon to be due and payable immediately, and
upon any such declaration the same shall become immediately due and payable.

          If an Event of Default described in clause (c) above with respect to
all series of Outstanding Securities, or any Event of Default described in
clause (d) or (e) above occurs and is continuing, then, and in each and every
such case, unless the principal of all the Securities shall have already become
due and payable, either the Trustee or the Holders of not less than 25% in
aggregate principal amount of all the Outstanding Securities (treated as one
class), by notice in writing to the Company (and to the Trustee if given by such
Holders), may declare the entire principal of all the Outstanding Securities, or
such lesser amount as may be provided for in the Securities, and interest
accrued thereon to be due and payable immediately, and upon any such declaration
the same shall become immediately due and payable.

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

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

               (i) all overdue installments of interest on and any Additional
     Amounts payable in respect of all Securities of that series (or upon all
     the Securities, as the case may be),

               (ii) the principal of (and premium, if any, on) any Securities of
     that series (or upon all the Securities, as the case may be) which have
     become due otherwise than by such declaration of acceleration and interest
     thereon at the rate or rates borne by or provided for in such Securities,

               (iii) to the extent that payment of such interest is lawful,
     interest upon overdue installments of interest and Additional Amounts at
     the rate or rates borne by or provided for in such Securities, and

                                       25

<PAGE>

               (iv) 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

          (b) all Events of Default with respect to Securities, other than the
non-payment of the principal of Securities which has 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 5.3 Collection of Indebtedness and Suits for Enforcement by
Trustee.

          The Company covenants that if

          (a) default is made in the payment of any installment of interest on
or any Additional Amounts payable in respect of any Security when such interest
or Additional Amounts shall have become due and payable and such default
continues for a period of 30 days, or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest and Additional
Amounts, if any, with interest upon the overdue principal (and premium, if any)
and, to the extent that payment of such interest shall be legally enforceable,
upon overdue installments of interest or any Additional Amounts, at the rate or
rates borne by or provided for in such Securities, and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

          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, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

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

          Section 5.4 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 or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

          (a) to file and prove a claim for the whole amount, or such lesser
amount as may be provided for in the Securities of that series, of principal
(and premium, if any) and interest and any Additional Amounts owing and unpaid
in respect of the Securities and to file such other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee (including
any claim for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents or 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 (or other similar
official) in any such judicial proceeding is hereby authorized by each Holder of
Securities 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 of
Securities, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel and any other amounts due the Trustee under Section 6.7.

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

          Section 5.5 Trustee May Enforce Claims Without Possession of
Securities.

          All rights of action and claims under this Indenture or any of the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery or 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 5.6 Application of Money Collected.

          Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (and premium,
if any), interest or any Additional Amounts, 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
6.7; and

          Second: To the payment of the amounts then due and unpaid upon the
Securities for principal (and premium, if any) and interest and any Additional
Amounts payable 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 aggregate amounts due and payable on such Securities for principal (and
premium, if any), interest and Additional Amounts, respectively; and

          Third: The balance, if any, to the Person or Persons entitled thereto.

          Section 5.7 Limitation on Suits.

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

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

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

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

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

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

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

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Sections 3.5 and 3.7) interest on and any Additional Amounts in respect of such
Security on the respective Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder.

          Section 5.9 Restoration of Rights and Remedies.

          If the Trustee or any Holder of a Security has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and the Holders of Securities shall, subject to
any determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

          Section 5.10 Rights and Remedies Cumulative.

          Except as provided in Section 5.7 and except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Securities in the last paragraph of Section 3.6, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders of Securities
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 by this Article or by law
to the Trustee or to the Holders of Securities may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders
of Securities.

          Section 5.12 Control by Holders of Securities.

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

                                       29

<PAGE>

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

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

          (c) such direction is not unduly prejudicial to the rights of other
Holders of Securities of such series.

          Section 5.13 Waiver of Past Defaults.

          Prior to a declaration of acceleration of the Maturity of the
Securities of any series as provided in Section 5.2, the Holders of not less
than a majority in principal amount of Outstanding Securities of any 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 or Event of Default described
in clause (c) of Section 5.1 which relates to less than all of the series of
Outstanding Securities, or the Holders of not less than a majority in principal
amount of all Outstanding Securities (voting as one class) may on behalf of all
Holders waive any past default or Event of Default described in said clause (c)
(which relates to all series of Outstanding Securities) or in clause (d) or (e)
of Section 5.1, except a default

          (a) in the payment of the principal of (and premium, if any) or
interest on or Additional Amounts payable in respect of any Security of such
series, 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,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit, other than the Trustee, of an undertaking to pay the costs of such suit,
and that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, including
the Trustee, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section shall
not apply to any suit instituted by the Company, the Trustee or by any Holder,
or group of Holders, holding in the aggregate more than 10% in principal amount
of the Outstanding Securities of any series, or to any suit instituted by any
Holder of any Security for the enforcement of the payment of the principal of
(and premium, if any) or interest on or any Additional Amounts in respect of any
Security on or after the respective Stated Maturity or

                                       30

<PAGE>

Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date) or interest on any overdue principal of any Security.

                                    ARTICLE 6

                                   THE TRUSTEE

          Section 6.1 Certain Duties and Responsibilities.

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

               (i) 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

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

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

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

               (i) this subsection shall not be construed to limit the effect of
     subsection (a) of this Section;

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

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

                                       31

<PAGE>

               (iv) no provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

          Section 6.2 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 Securities of such series entitled to receive reports pursuant to
Section 7.3(c), notice of such default hereunder known to a Responsible Officer
of 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 on, or any Additional Amounts with respect
to, any Security of such series or in the payment of any sinking fund
installment with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and responsible
officers of the Trustee in good faith determine that the withholding of such
notice is in the interests of the Holders of Securities of such series; and
provided further, that in the case of any default of the character specified in
Section 5.1(c) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default, with
respect to Securities of such series. A default shall not be considered known to
a Responsible Officer of the Trustee unless it is a default in the payment of
principal (and premium, if any) or interest when due under Section 5.1(a) or (b)
or a Responsible Officer of the Trustee shall have received written notice
thereof, in accordance with this Indenture, from the Company or from the holders
of a majority in principal amount of the outstanding Securities of the series to
which the default relates.

          Section 6.3 Certain Rights of Trustee.

          Except as otherwise provided in Section 6.1:

          (a) the Trustee may rely and shall be 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 reasonably believed by it to be genuine and to
have been signed or presented by the proper party or parties;

          (b) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order (other than
delivery of any Security to the Trustee for authentication and delivery pursuant
to Section 3.3, 3.5 or 3.6 which shall be sufficiently evidenced as provided
therein) and any resolution of the Board of Directors may be sufficiently
evidenced by a Board Resolution;

                                       32
<PAGE>

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

          (d) the Trustee may consult with counsel and the written advice of
such counsel or any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon;

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

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

          (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

          (h) the Trustee shall not be liable for interest on or the investment
of any money received by it except as the Trustee may agree with the Company;

          (i) the permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty, and the Trustee shall not be
answerable for other than its negligence or willful misconduct; and

          (j) the rights, privileges, protections, immunities and benefits given
to the Trustee, including, but not limited to, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, whether as agent or otherwise, and to each agent, custodian and other
person employed to act hereunder.

          Section 6.4 Not Responsible for Recitals or Issuance of Securities.

          The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, shall be taken as the statements of the
Company, and the Trustee or any Authenticating Agent assumes no responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities. The Trustee

                                       33

<PAGE>

or any Authenticating Agent shall not be accountable for the use or application
by the Company of Securities or the proceeds thereof.

          Section 6.5 May Hold Securities.

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

          Section 6.6 Money Held in Trust.

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

          Section 6.7 Compensation and Reimbursement.

          The Company agrees

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

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

          (c) to indemnify the Trustee and its directors, officers, employees
and agents for, and to hold them harmless against, any loss, liability or
expense incurred without negligence or willful misconduct on their part, arising
out of or in connection with the acceptance or administration of the trust or
trusts hereunder, including the costs and expenses of defending themselves
against any claim or liability in connection with the exercise or performance of
any of their powers or duties hereunder.

          As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of (or premium, if any)
or interests on or any Additional Amounts with respect to the Securities.

          Section 6.8 Disqualifications; Conflicting Interests. If the Trustee
has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall

                                       34

<PAGE>

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

          Section 6.9 Corporate Trustee Required; Eligibility.

          There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State or the District of Columbia, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000 and subject to supervision or examination by 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, 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. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

          Section 6.10 Resignation and Removal; Appointment of Successor.

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee 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 the
instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to such
series.

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

          (d) If at any time:

               (i) the Trustee shall fail to comply with Section 6.8 after
     written request therefor by the Company or by any Holder of a Security who
     has been a bona fide Holder of a Security for at least six months, or

               (ii) the Trustee shall cease to be eligible under Section 6.9 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder of a Security, or

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

                                       35

<PAGE>

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 5.14, any
Holder of a Security who has been a bona fide Holder of a Security of any series
for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the
Trustee with respect to all Securities of such series and the appointment of a
successor Trustee or Trustees. Such courts may thereupon, after such notice, if
any, as it may deem proper, remove the Trustee and appoint a successor Trustee
with respect to such Securities.

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

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first class mail, postage prepaid, to the
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

          Section 6.11 Acceptance of Appointment by Successor.

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

                                       36

<PAGE>

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

          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, 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 that no Trustee shall be responsible for any notice
given to, or received by, or any act or failure to act on the part of any other
Trustee hereunder, 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, such retiring Trustee shall with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates have no further responsibility for the exercise
of rights and powers or for the performance of the duties and obligations vested
in the Trustee under this Indenture other than as hereinafter expressly set
forth, 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, to the extent contemplated by
such supplemental indenture, the property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

          (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, 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.

          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

                                       37

<PAGE>

consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee, by sale or otherwise, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

          Section 6.13 Preferential Collection of Claims Against Company.

          (a) Subject to Subsection (b) of this Section, if the Trustee shall be
or shall become a creditor, directly or indirectly, secured or unsecured, of the
Company within four months prior to a default, as defined in Subsection (c) of
this Section, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the
Securities and the holders of other indenture securities (as defined in
Subsection (c) of this Section):

               (i) an amount equal to any and all reductions in the amount due
     and owing upon any claim as such creditor in respect of principal or
     interest, effected after the beginning of such four month period and valid
     as against the Company and its other creditors, except any such reduction
     resulting from the receipt or disposition of any property described in
     paragraph (ii) of this Subsection, or from the exercise of any right of
     set-off which the Trustee could have exercised if a petition in bankruptcy
     had been filed by or against the Company upon the date of such default; and

               (ii) all property received by the Trustee in respect of any claim
     as such creditor, either as security therefor, or in satisfaction or
     composition thereof, or otherwise, after the beginning of such four-month
     period, or an amount equal to the proceeds of any such property, if
     disposed of, subject, however, to the rights, if any, of the Company and
     its other creditors in such property or such proceeds.

          Nothing herein contained, however, shall affect the right of the
Trustee:

               (iii) to retain for its own account (i) payments made on account
     of any such claim by any Person (other than the Company) who is liable
     thereon, and (ii) the proceeds of the bona fide sale of any such claim by
     the Trustee to a third person, and (iii) distributions made in cash,
     securities or other property in respect of claims filed against the Company
     in bankruptcy or receivership or in proceedings for reorganization pursuant
     to the Federal Bankruptcy Code or applicable State law;

               (iv) to realize, for its own account, upon any property held by
     it as security for any such claim, if such property was so held prior to
     the beginning of such four-month period;

               (v) to realize, for its own account, but only to the extent of
     the claim hereinafter mentioned, upon any property held by it as security
     for any such claim, if

                                       38

<PAGE>

     such claim was created after the beginning of such four month period and
     such property was received as security therefor simultaneously with the
     creation thereof, and if the Trustee shall sustain the burden of proving
     that at the time such property was so received the Trustee had no
     reasonable cause to believe that a default, as defined in Subsection (c) of
     this Section, would occur within four months; or

               (vi) to receive payment on any claim referred to in paragraph
     (ii) or (iii), against the release of any property held as security for
     such claim as provided in paragraph (ii) or (iii), as the case may be, to
     the extent of the fair value of such property.

          For the purposes of paragraphs (ii), (iii) and (iv) immediately above,
property substituted after the beginning of such four-month period for property
held as security at the time of such substitution shall, to the extent of the
fair value of the property released, have the same status as the property
released, and, to the extent that any claim referred to in any of such
paragraphs is created in renewal of or in substitution for or for the purpose of
repaying or refunding any pre-existing claim of the Trustee as such creditor,
such claim shall have the same status as such pre-existing claim.

          If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned
between the Trustee, the Holders of Securities and the holders of other
indenture securities in such manner that the Trustee, the Holders of Securities
and the holders of other indenture securities realize, as a result of payments
from such special account and payments of dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Code or applicable State law, the same
percentage of their respective claims, figured before crediting to the claim of
the Trustee anything on account of the receipt by it from the Company of the
funds and property in such special account and before crediting to the
respective claims of the Trustee and the Holders of Securities and the holders
of other indenture securities dividends on claims filed against the Company in
bankruptcy or receivership or in proceedings for reorganization pursuant to the
Federal Bankruptcy Code or applicable State law, but after crediting thereon
receipts on account of the indebtedness represented by their respective claims
from all sources other than from such dividends and from funds and property so
held in such special account. As used in this paragraph, with respect to any
claim, the term "dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or proceedings for reorganization pursuant
to the Federal Bankruptcy Code or applicable State law, whether such
distribution is made in cash, securities or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim. The court in which such bankruptcy, receivership or proceedings for
reorganization is pending shall have jurisdiction (i) to apportion between the
Trustee and the Holders of Securities and the holders of other indenture
securities, in accordance with the provisions of this paragraph, the funds and
property held in such special account and proceeds thereof, or (ii) in lieu of
such apportionment, in whole or in part, to give to the provisions of this
paragraph due consideration in determining the fairness of the distributions to
be made to the Trustee and the Holders of Securities and the holders of other
indenture securities with respect to their respective claims, in which event it
shall not be necessary to liquidate or to appraise the value of any securities
or other property held in such special account or as security for any such
claim, or to make a specific account or as security for any such claim, or to
make a specific allocation of such distributions as between the secured and

                                       39

<PAGE>

unsecured portions of such claims, or otherwise to apply the provisions of this
paragraph as a mathematical formula.

          Any Trustee which has resigned or been removed after the beginning of
such four-month period shall be subject to the provisions of this Subsection as
though such resignation or removal had not occurred. If any Trustee has resigned
or been removed prior to the beginning of such four-month period, it shall be
subject to the provisions of this Subsection if and only if the following
conditions exist:

                    (1) the receipt of property or reduction of claim, which
          would have given rise to the obligation to account, if such Trustee
          had continued as Trustee, occurred after the beginning of such four
          month period; and

                    (2) such receipt of property or reduction of claim occurred
          within four months after such resignation or removal.

          (b) There shall be excluded from the operation of Subsection (a) of
this Section a creditor relationship arising from:

               (i) the ownership or acquisition of securities issued under any
     indenture, or any security or securities having a maturity of one year or
     more at the time of acquisition by the Trustee;

               (ii) advances authorized by a receivership or bankruptcy court of
     competent jurisdiction, or by this Indenture, for the purpose of preserving
     any property which shall at any time be subject to the lien of this
     Indenture or of discharging tax liens or other prior liens or encumbrances
     thereon, if notice of such advances and of the circumstances surrounding
     the making thereof is given to the Holders of Securities at the time and in
     the manner provided in this Indenture;

               (iii) disbursements made in the ordinary course of business in
     the capacity of trustee under an indenture, transfer agent, registrar,
     custodian, paying agent, fiscal agent or depositary, or other similar
     capacity;

               (iv) an indebtedness created as a result of services rendered or
     premises rented; or an indebtedness created as a result of goods or
     securities sold in a cash transaction, as defined in Subsection (c) of this
     Section;

               (v) the ownership of stock or of other securities of a
     corporation organized under the provisions of Section 25(a) of the Federal
     Reserve Act, as amended, which is directly or indirectly a creditor of the
     Company; or

               (vi) the acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within the
     classification of self-liquidating paper as defined in Subsection (c) of
     this Section.

          (c) For the purpose of this Section only:

               (i) the term "default" means any failure to make payment in full
     of the principal of or interest on any of the Securities or upon the other
     indenture securities when and as such principal or interest becomes due and
     payable;

               (ii) the term "other indenture securities" means securities upon
     which the Company is an obligor outstanding under any other indenture (i)
     under which indenture and as to which securities the Trustee is also
     trustee, (ii) which contains provisions substantially similar to the
     provisions of this Section, and (iii) under which a default exists at the
     time of the apportionment of the funds and property held in such special
     account;

               (iii) the term "cash transaction" means any transaction in which
     full payment for goods or securities sold is made within seven days after
     delivery of the goods or securities in currency or in checks or other
     orders drawn upon banks or bankers and payable upon demand;

               (iv) the term "self-liquidating paper" means any draft, bill of
     exchange, acceptance or obligation which is made, drawn, negotiated or

     merchandise and which is secured by documents evidencing title to,
     possession of, or lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation;

               (v) the term "Company" means any obligor upon the Securities; and

          Section 6.14 Appointment of Authenticating Agent

          The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue or exchange, registration of transfer or partial redemption thereof or
pursuant to Section 3.6, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such

                                       41

<PAGE>

Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

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

          The Trustee agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 6.7.

          The provisions of Sections 3.8, 6.4 and 6.5 shall be applicable to
each Authenticating Agent.

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

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

          If all of the Securities of any series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not comply
with Section 1.2) by the Company, shall appoint in accordance with this Section
6.14 an Authenticating Agent having an office in a Place of Payment designated
by the Company with respect to such series of Securities.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

          Section 7.1 Company To Furnish Trustee Names and Addresses of Holders.

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

          (a) semi-annually, not later than __________ and __________ each year,
a list, in such form as the Trustee may reasonably require, of the names and
addresses of the Holders of Securities of such series as of the __________ and
__________ preceding such __________ or __________, and

          (b) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished, provided, however, that, so long as the Trustee is the Security
Registrar, no such list shall be required to be furnished.

          Section 7.2 Preservation of Information; Communications to Holders.

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders of Securities (i) contained in
the most recent list furnished to the Trustee for each series as provided in
Section 7.1, and (ii) received by the Trustee for each series in the capacity of
Security Registrar if the Trustee is then acting in such capacity. The Trustee
may destroy any list furnished to it as provided in Section 7.1 upon receipt of
a new list so furnished.

          (b) If three or more Holders of Securities of any series (hereinafter
referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that

                                       43

<PAGE>

each such applicant has owned a Security of such series for a period of at least
six months preceding the date of such application, and such application states
that the applicants desire to communicate with other Holders of Securities of
such series or with the Holders of all Securities with respect to their rights
under this Indenture or under the Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit,
then the Trustee shall, within five business days after the receipt of such
application, at its election, either

               (i) afford such applicants access to the information preserved at
     the time by the Trustee in accordance with Section 7.2(a), or

               (ii) inform such applicants as to the approximate number of
     Holders of Securities whose names and addresses appear in the information
     preserved at the time by the Trustee in accordance with Section 7.2(a), and
     as to the approximate cost of mailing to such Holders the form of proxy or
     other communication, if any, specified in such application.

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

          (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any Paying Agent nor any Security Registrar shall be held accountable by
reason of the disclosure of any such information as to the names and addresses
of the Holders of Securities in accordance with Section 7.2(b), regardless of
the source from which such information was derived, and that the Trustee shall
not be held accountable by reason of mailing any material pursuant to a request
made under Section 7.2(b).

          Section 7.3 Reports by Trustee.

          (a) Within 60 days after __________ of each year commencing with the
year 20__, the Trustee shall transmit by mail to all Holders of Securities, if
required by Section 313(a) of the Trust Indenture Act and as provided in
Subsection (c) of this Section, a brief report dated as of such May 15 with
respect to:

               (i) its eligibility under Section 6.9 and its qualifications
     under Section 6.8, or in lieu thereof, if to the best of its knowledge it
     has continued to be eligible and qualified under said Sections, a written
     statement to such effect;

               (ii) the character and amount of any advances (and if the Trustee
     elects so to state, the circumstances surrounding the making thereof) made
     by the Trustee (as such) which remain unpaid on the date of such report,
     and for the reimbursement of which it claims or may claim a lien or charge,
     prior to that of the Securities, on any property or funds held or collected
     by it as Trustee, except that the Trustee shall not be required (but may
     elect) to report such advances if such advances so remaining unpaid
     aggregate not more than 1/2 of 1% of the principal amount of the Securities
     Outstanding on the date of such report;

               (iii) the amount, interest rate and maturity date of all other
     indebtedness owing by the Company (or by any other obligor on the
     Securities) to the Trustee in its individual capacity, on the date of such
     report, with a brief description of any property held as collateral
     security therefor, except an indebtedness based upon a creditor
     relationship arising in any manner described in Section 6.13(b)(ii), (iii),
     (iv) or (vi);

               (iv) the property and funds, if any, physically in the possession
     of the Trustee as such on the date of such report;

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

               (vi) any action taken by the Trustee in the performance of its
     duties hereunder which it has not previously reported and which in its
     opinion materially affects the Securities, except action in respect of a
     default, notice of which has been or is to be withheld by the Trustee in
     accordance with Section 6.2, provided however, that if the Trust Indenture
     Act is amended subsequent to the date hereof to eliminate the requirement
     of the Trustee's brief report, the report required by this Section need not
     be transmitted to any Holders.

          (b) The Trustee shall transmit by mail to all Holders of Securities,
as provided in subsection (c) to this Section, a brief report with respect to
the character and amount of any advances (and if the Trustee elects so to state,
the circumstances surrounding the making thereof) made by the Trustee (as such)
since the date of the last report transmitted pursuant to subsection (a) of this
Section (or if no such report has yet been so transmitted, since the date of
execution of this instrument) for the reimbursement of which it claims or may
claim a lien or charge, prior to that of the Securities, on property or funds
collected by it as Trustee, and which it has not previously reported pursuant to
this subsection, except that the Trustee shall not be required (but

                                       45

<PAGE>

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

          (c) Reports pursuant to this Section and Section 6.2 shall be

     such Holders appear in the Security Register; and

               (ii) except in the case of reports pursuant to subsection (b) of
     this Section, to each Holder of a Security whose name and address is
     preserved at the time by the Trustee, as provided in Section 7.2(a).

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

          Section 7.4 Reports by the Company.

          The Company shall:

          (a) file with the Trustee, within 30 days after the Company is
required to file the same with the Commission, copies of the annual reports and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) which the Company may be required to file with the

time in such rules and regulations;

          (b) file with the Trustee and Commission, in accordance with rules and

information, documents and reports with respect to compliance by the Company
with the conditions and covenants of this Indenture as may be required from time
to time by such rules and regulations; and

          (c) transmit within 30 days after the filing thereof with the Trustee,
in the manner and to the extent provided in Section 7.3(c) with respect to

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

          Section 8.1 Consolidations and Mergers of Company and Sales, Leases
and Conveyances Permitted Subject to Certain Conditions.

          Notwithstanding anything contained herein or in any of the Securities,
the Company may consolidate with, or sell, lease or convey all or substantially
all of its assets to, or merge with or into any other corporation, provided that
in any such case, either the Company shall be the continuing corporation, or the
successor corporation shall be a corporation organized and existing under the
laws of the United States of America or a State thereof and such successor
corporation shall expressly assume the due and punctual payment of the principal
of (and premium, if any), any interest on, and any Additional Amounts payable
pursuant to Section 10.4 with respect to, all the Securities, according to their
tenor, and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by the Company by
supplemental Indenture satisfactory to the Trustee, executed and delivered to
the Trustee by such successor corporation.

          Section 8.2 Rights and Duties of Successor Corporation.

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

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

          Section 8.3 Officers' Certificate and Opinion of Counsel.

          The Trustee, subject to the provisions of Sections 6.1 and 6.3, may
receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale, lease or conveyance, and any
such assumption and any such

                                       47

supplemental indenture, if any, complies with the provisions of this Article and
that all conditions precedent herein provided relating to such transactions have
been complied with.

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

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

          (c) to change or eliminate any restrictions on the payment of
principal (or premium, if any) on Securities or to permit or facilitate the
issuance of Securities in uncertificated form, provided any such action shall
not adversely affect the interests of the Holders of Securities of any series in
any material respect; or

          (d) to change or eliminate any provision of this Indenture, provided
that any such change or elimination (i) shall become effective only when there
is no Security Outstanding of any series created prior to the execution of such
supplemental indenture which is entitled to the benefit of such provision or
(ii) shall not apply to any Security Outstanding; or

          (e) to establish the form or terms of Securities of any series as
permitted by Sections 2.1 and 3.1; or

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

          (g) to cure any ambiguity, to correct or supplement any provision
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Indenture which shall not adversely affect the interest of the
Holders of Securities of any series in any material respect; or

                                       48
<PAGE>

          (h) to add to, delete from or revise the conditions, limitations and
restrictions on the authorized amount, terms or purposes of issue,
authentication and delivery of Securities, as herein set forth; or

          (i) to add any additional Events of Default (and if such Events of
Default are to be applicable to less than all series of Securities stating that
such Events of Default are expressly being included solely to be applicable to
such series); or

          (j) to add to or change or eliminate any provision of this Indenture
as shall be necessary or desirable in accordance with any amendments to the
Trust Indenture Act, provided such action shall not adversely affect the
interest of the Holders of the Securities of any series in any material respect.

          Section 9.2 Supplemental Indentures with Consent of Holders.

          With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by 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,

          (a) change the Stated Maturity of the principal of, or any installment
of interest on, any Security, or reduce the principal amount thereof or the rate
of interest thereon or any Additional Amounts payable in respect thereof, or any
premium payable upon the redemption thereof, or change the obligation of the
Company to pay Additional Amounts pursuant to Section 10.4 (except as
contemplated by Section 8.1 and permitted by Section 9.1(a)), or reduce the
amount of the principal of an Original Issue Discount Security that would be due
and payable upon a declaration of acceleration of the maturity thereof pursuant
to Section 5.2, or change any Place of Payment where, or the coin or currency in
which, any Security or any premium or the interest thereon is payable, or impair
the right to institute suit for the enforcement of any such payment on or after
the Stated Maturity thereof (or, in the case of redemption, on or after the
Redemption Date), or

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

          (c) modify any of the provisions of this Section, or Section 5.13, or
Section 10._, 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, or

                                       49

<PAGE>

          (d) adversely affect the right to repayment, if any, of Securities of
any series at the option of the Holders thereof.

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

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

          Section 9.3 Execution of Supplemental Indentures.

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trust created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

          Section 9.4 Effect of Supplemental Indentures.

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

          Section 9.5 Conformity with Trust Indenture Act.

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

          Section 9.6 Reference in Securities to Supplemental Indentures.

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

          Section 10.1 Payment of Principal, Premium, if any, and Interest.

          The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of
(and premium, if any), interest on and any Additional Amounts payable in respect
of the Securities of that series in accordance with the terms of such series of
Securities and this Indenture.

          Section 10.2 Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency. Unless otherwise set forth in a Board Resolution or indenture
supplemental hereto with respect to a series of Securities, the Company hereby
designates as the Place of Payment for each series of Securities the Borough of
Manhattan, The City of New York, and initially appoints the Trustee at its
Corporate Trust Offices as the Company's office or agency for each of such
purposes in such city.

          Section 10.3 Money for Securities Payments To Be Held in Trust.

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

          Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
(and premium, if any), or

                                       51

<PAGE>

interest on, any Securities of that series, deposit with a Paying Agent a sum
sufficient to pay the principal (and premium, if any) or interest so becoming
due, such sum to be held in trust for the benefit of the Persons entitled to
such principal, premium 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 for any series of Securities
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, that such Paying Agent will

          (a) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Securities of that series 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 (and premium, if any) or interest on the Securities of that series;
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.

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

          Except as otherwise provided in the form of Securities of any
particular series pursuant to the provisions of this Indenture, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium, if any) or interest on
any Security of any series and remaining unclaimed for two years after such
principal (and premium, if any) or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in an Authorized Newspaper in each Place of Payment or to be
mailed to Holders of Securities, or both, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication or mailing, any unclaimed balance of
such money then remaining will be repaid to the Company. In the absence of a
written request from the Company to return unclaimed funds to the Company, the
Trustee shall from time to time deliver all unclaimed funds to or as directed by
applicable escheat authorities,

                                       52

<PAGE>

as determined by the Trustee in its sole discretion, in accordance with the
customary practices and procedures of the Trustee. Any unclaimed funds held by
the Trustee pursuant to this section shall be held uninvested and without any
liability for interest.

          Section 10.4 Additional Amounts.

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

          If the Securities of a series provide for the payment of Additional
Amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal (and
premium, if any) is made, and at least 10 days prior to each date of payment of
principal (and premium, if any) or interest, if there has been any change with
respect to the matters set forth in the below-mentioned Officers' Certificate),
the Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal (and premium, if any) or interest on the Securities of that
series shall be made to Holders of Securities of that series who are United
States Aliens without withholding for or on account of any tax, assessment or
other governmental charge described in the Securities of that series. If any
such withholding shall be required, then such Officers' Certificate shall
specify by country the amount, if any, required to be withheld on such payments
to such Holders of Securities and the Company will pay to the Trustee or such
Paying Agent the Additional Amounts required by the terms of such Security and
the first paragraph of this Section. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without negligence or bad faith on
their part arising out of or in connection with actions taken or omitted by any
of them in reliance on any Officers' Certificate furnished pursuant to this
Section.

          Section 10.5 Statement as to Compliance; Notice of Certain Defaults.

          (a) The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year, a written statement, which need not comply with Section
1.2, signed by the principal executive officer, the principal financial officer
or the principal accounting officer of the Company, stating that

                                       53

<PAGE>

               (i) a review of the activities of the Company and its
     subsidiaries during such year and of performance under this Indenture has
     been made under his supervision, and

               (ii) to the best of his knowledge, based on such review, (a) the
     Company has fulfilled all of its obligations under this Indenture
     throughout such year, or, if there has been a default in the fulfillment of
     any such obligation, specifying each such default known to him and the
     nature and status thereof, and (b) no event has occurred and is continuing
     which is, or after notice or lapse of time or both would become, an Event
     of Default, or, if such event has occurred and is continuing, specifying
     each such event known to him and the nature and status thereof.

          (b) The Company will deliver to the Trustee within five days after the
occurrence thereof, written notice of any event which after notice or lapse of
time or both would become an Event of Default pursuant to clause (d) of Section
5.1.

          Section 10.6 [ADDITIONAL COVENANTS, IF ANY]

          Section 10._ Waiver of Certain Covenants.

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section [10.__] with respect to the
Securities of any series if before the time for such compliance the Holders of
at least a majority in principal amount of the Outstanding Securities of such
series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                            REDEMPTION OF SECURITIES

          Section 11.1 Applicability of Article.

          Securities of any series which are redeemable at the option of the
Company before their Stated Maturity shall be redeemable in accordance with the
terms of such Securities and (except as otherwise specified as contemplated by
Section 3.1 for Securities of any series) this Article. Securities of any series
which are redeemable at the option of the Holder before their Stated Maturity
shall be redeemable in accordance with the terms of such Securities and (except
as otherwise specified as contemplated by Section 3.1 for Securities of any
series) Sections 11.5 and 11.6 of this Article.

          Section 11.2 Election to Redeem; Notice to Trustee

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company of the Securities of

                                       54

<PAGE>

any series, the Company shall, at least 60 days prior to the Redemption Date
fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date, the principal amount of
Securities of such series to be redeemed and the relevant terms of the
Securities to be redeemed. The election of a Holder to redeem any Securities
shall be evidenced by a writing by a Holder sent to the Trustee and the Company
at least 60 days prior to the Redemption Date fixed by the Holder in such notice
(unless a shorter notice period shall be satisfactory to the Trustee). Such
notice shall notify the Trustee and the Company of such Redemption Date, the
principal amount of Securities of such series to be redeemed and any relevant
terms of the Securities of such series to be redeemed.

          Section 11.3 Selection by Trustee of Securities To Be Redeemed.

          If less than all the Securities of any series having the same terms
are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee from the
Outstanding Securities of such series not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and which may provide
for the selection for redemption of portions (equal to the minimum authorized
denomination for Securities of such series or any integral multiple thereof
which is also an authorized denomination) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of such series.

          The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) 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 of such Securities which has been or is to be redeemed.

          Section 11.4 Notice of Redemption.

          Notice of redemption shall be given in the manner provided in Section
1.6, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the Securities to be redeemed (which shorter
period shall be acceptable to the Trustee), to the Holders of Securities to be
redeemed. Failure to give notice by mailing in the manner herein provided to the
Holder of any Securities designated for redemption as a whole or in part, or any
defect in the notice to any such Holder, shall not affect the validity of the
proceedings for the redemption of any other Securities or portion thereof. Any
notice that is mailed to the Holder of any Securities in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
such Holder receives the notice.

          All notices of redemption shall state:

          (a) the Redemption Date,

          (b) the Redemption Price (or the method of calculating the Redemption
Price) and accrued interest, if any,

                                       55

<PAGE>

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

          (d) in case any Security is to be redeemed in part only, the notice
which relates to such Security shall state that on and after the Redemption
Date, upon surrender of such Security, the Holder of such Security will receive,
without charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed,

          (e) 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 shall cease to accrue on and after said date,

          (f) the Place or Places of Payment where such Securities are to be
surrendered for payment of the Redemption Price, and

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

          A notice of redemption published as contemplated by Section 1.6 need
not identify particular Securities to be redeemed.

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

          Section 11.5 Deposit of Redemption Price.

          On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 10.3) 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 and any Additional
Amounts with respect thereto, all the Securities or portions thereof which are
to be redeemed on that date.

          Section 11.6 Securities Payable on Redemption Date.

          Notice of redemption having been given by the Holder to the Company
and Trustee pursuant to Section 11.2 or to the Holder by the Company or the
Trustee pursuant to Section 11.4, the Securities so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein
specified, and from and after such date (unless the Company shall default in the
payment of the Redemption Price and accrued interest) such Securities shall
cease to bear interest. Upon surrender of any such Security for redemption in
accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued interest (and any Additional Amounts) to
the Redemption Date; provided, however, that installments of interest on

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

          Section 11.7 Securities Redeemed in Part.

          Any Security which is to be redeemed only in part shall be surrendered
at any office or agency of the Company maintained for that purpose pursuant to
Section 10.2 (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, containing identical terms and provisions, of
any authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                 SINKING FUNDS

          Section 12.1 Applicability of Article.

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series, except as otherwise specified as
contemplated by Section 3.1 for Securities of such series or as otherwise
permitted or required by any form of Security of such series issued pursuant to
this Indenture.

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such series is herein referred to as
an "optional sinking fund payment." If provided for by the terms of Securities
of any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 12.2. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

          Section 12.2 Satisfaction of Sinking Fund Payments with Securities.

          The Company may, in satisfaction of all or any part of any sinking
fund payment with respect to the Securities of a series to be made pursuant to
the terms of such Securities as provided for by the terms of such series, (1)
deliver Outstanding Securities of such series (other than any of such Securities
previously called for redemption) theretofore purchased or receive credit for
Securities (not previously so credited) theretofore purchased by the Company and
delivered to the Trustee for cancellation pursuant to Section 3.9, and (2) apply
as a credit Securities of such series which have been redeemed either at the
election of the Company pursuant to the terms of such series of Securities or
through the application of permitted optional sinking fund payments pursuant to
the terms of such Securities, provided that such Securities have not been
previously so credited. Such Securities shall be received and credited for such
purpose by the Trustee at the Redemption Price specified in such Securities for
redemption

through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the principal amount of Securities of such series to be redeemed in order
to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee
need not call Securities of such series for redemption, except upon Company
Request, and such cash payment shall be held by the Trustee or a Paying Agent
and applied to the next succeeding sinking fund payment, provided, however, that
the Trustee or such Paying Agent shall at the request of the Company from time
to time pay over and deliver to the Company any cash payment so being held by
the Trustee or such Paying Agent upon delivery by the Company to the Trustee of
Securities of that series purchased by the Company having an unpaid principal
amount equal to the cash payment requested to be released to the Company.

          Section 12.3 Redemption of Securities for Sinking Fund.

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officers' Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 30 days before each such sinking fund payment date the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 11.3 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 11.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.6 and 11.7.
