      in respect of which there shall have been presented to the Trustee proof
      satisfactory to it that such Securities are held by a bona fide purchaser
      in whose hands such Securities are valid obligations of the Company;

PROVIDED, HOWEVER, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, Securities owned
by the Company or any other obligor upon the Securities or any Affiliate of the
Company or of such other obligor shall be disregarded and deemed not to be
Outstanding, except that, in determining whether the Trustee shall be protected
in relying upon any such request, demand, authorization, direction, notice,
consent or waiver, only Securities which a Responsible Officer of the Trustee
actually knows to be so owned shall be so disregarded. Securities so owned which
have been pledged in good faith may be regarded as Outstanding if the pledgee
establishes to the satisfaction of the Trustee the pledgee's right so to act
with respect to such Securities and that the pledgee is not the Company or any
other obligor upon the Securities or any Affiliate of the Company or of such
other obligor. In case of a dispute as to such right, any decision by the
Trustee shall be full protection to the Trustee. Upon request of the Trustee,
the Company shall furnish to the Trustee promptly an Officers' Certificate
listing and identifying all Securities, if any, known by the Company to be owned
or held by or for the account of any of the above-described persons; and,
subject to Section 6.01, the Trustee shall be entitled to accept such Officers'

any such determination.

Section 1.02 COMPLIANCE CERTIFICATES AND OPINIONS.

            Upon any application or request by the Company to the Trustee to
take any action under any provision of this Indenture, the Company shall furnish
to the Trustee an Officers' Certificate stating that all conditions precedent,
if any, provided for in this Indenture relating to the proposed action have been
complied with and, where appropriate as to matters of law, an Opinion of Counsel

condition or covenant provided for in this Indenture shall include:

            (1) a statement that the Person signing such certificate or opinion

Section 1.03 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
reasonable care should know, that the certificate or opinion or representations
with respect to such matters is erroneous. Any certificate of counsel or Opinion
of Counsel may be based, insofar as it relates to fac-

<PAGE>
                                      -7-

tual matters, upon a certificate or opinion of, or representations by, an
officer or officers of the Company stating that the information with respect to
such factual matters is in the possession 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.

Section 1.04 ACTS OF HOLDERS.

            (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section 1.04.

            (b) The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may be proved in
accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in any reasonable manner which the Trustee deems sufficient.

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

            (d) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a Board Resolution, fix in advance
a record date for the determination of Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Notwithstanding Trust Indenture Act
Section 316(c), such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not earlier than the
date 30 days prior to the first solicitation of Holders generally in connection
therewith and not later than the date such solicitation is completed. If such a
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act maybe given before or after such record date, but
only the Holders 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 shall be computed as of such
record date; PROVIDED, HOWEVER, that no such authorization, agreement or consent
by such Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than
eleven months after the record date.

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

Section 1.05 NOTICES, ETC., TO TRUSTEE AND COMPANY.

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

            (1) the Trustee by any Holder or by the Company shall be sufficient
      for every purpose hereunder if made, given, furnished or filed in writing
      (including a facsimile transmission) to or with the Trustee at its
      Corporate Trust Office, Attention: Corporate Trust Administration, or

            (2) the Company by the Trustee or by any Holder shall be sufficient
      for every purpose hereunder (unless otherwise herein expressly provided)
      if in writing (including a facsimile transmission) and mailed, first-class
      postage prepaid, to the Company addressed to it at the address of its
      principal office specified in the first paragraph of this instrument or at
      any other address previously furnished in writing to the Trustee by the
      Company, to the attention of the general counsel of the Company.

Section 1.06 NOTICE TO HOLDERS; WAIVER.

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

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

Section 1.07 CONFLICT WITH TRUST INDENTURE ACT.

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

Section 1.10 SEPARABILITY CLAUSE.

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

Section 1.11 BENEFITS OF INDENTURE.

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

Section 1.12 GOVERNING LAW; WAIVER OF JURY TRIAL.

            This Indenture and the Securities shall be governed by and construed
in accordance with the laws of the State of New York, and for all purposes will
be construed in accordance with the laws of said State without giving effect to
principles of conflicts of laws of such State.

      EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY
IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES
OR THE TRANSACTION CONTEMPLATED HEREBY.

Section 1.13 LEGAL HOLIDAYS.

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

Section 1.14 REFERENCES TO CURRENCY.

            All references in this Indenture to "dollars" or "$" are to the
currency of the United States of America.

Section 1.15 FORCE MAJEURE.

            In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of
or caused by, directly or indirectly, forces beyond its control, including,
without limitation, strikes, work stoppages, accidents, acts of war or
terrorism, civil or military disturbances, nuclear or natural catastrophes or
acts of God, and interruptions, loss or malfunctions of utilities,
communications or computer (software and hardware) services; it being understood
that the Trustee shall use reasonable efforts which are consistent with accepted
practices in the banking industry to resume performance as soon as practicable
under the circumstances.

                                                    Authorized Signatory"

Section 2.03 SECURITIES ISSUABLE IN THE FORM OF A GLOBAL SECURITY.

            (a) If the Issuer shall establish pursuant to Sections 2.01 and 3.01
that the Securities of a particular series are to be issued in whole or in part
in the form of one or more Global Securities, then the Issuer shall execute and
the Trustee shall, in accordance with Section 3.03 and the Company Order
delivered to the Trustee thereunder, authenticate and deliver, such Global
Security or Securities, which (i) shall represent, and shall be denominated in
an amount equal to the aggregate principal amount of, the Outstanding Securities
of such series to be represented by such Global Security or Securities, (ii)
shall be registered in the name of the Depositary for such Global Security or
Securities or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or its custodian or pursuant to the 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 THE INDIVIDUAL SECURITIES REPRESENTED
HEREBY, THIS GLOBAL SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE (I) BY THE
DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR

<PAGE>
                                      -11-

(II) BY A NOMINEE OF THE DEPOSITARY OR THE DEPOSITARY 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."

            (b) Notwithstanding any other provision of this Section 2.03 or of
Section 3.05, unless the terms of a Global Security expressly permit such Global
Security to be exchanged in whole or in part for individual Securities, a Global
Security may be transferred, in whole but not in part and in the manner provided
in Section 3.05, only to another nominee of the Depositary for such Global
Security, or to a successor Depositary for such Global Security selected or
approved by the Issuer or to a nominee of such successor Depositary.

            (c) (i) If at any time the Depositary for a Global Security notifies
the Issuer that it is unwilling or unable to continue as Depositary for such
Global Security or if at any time the Depositary for the Securities for such
series shall no longer be eligible or in good standing under the Securities
Exchange Act of 1934, as amended, or other applicable statute or regulation, the
Issuer shall appoint a successor Depositary with respect to such Global
Security. If a successor Depositary for such Global Security is not appointed by
the Issuer within 90 days after the Issuer receives such notice or becomes aware
of such ineligibility, the Issuer will execute a Company Order for the
authentication and delivery of individual Securities of such series in exchange
for such Global Security, and the Trustee, upon receipt of such Company Order,
will authenticate and deliver individual Securities of such series of like tenor
and terms in definitive form in an aggregate principal amount equal to the
principal amount of the Global Security in exchange for such Global Security.

            (ii) If an Event of Default shall have occurred and be continuing or
an event shall have occurred which with the giving of notice or lapse of time or
both, would constitute an Event of Default with respect to the Securities
represented by such Global Security, the Trustee, upon receipt of a Company
Order for the authentication and delivery of individual Securities of such
series in exchange for such Global Security, will authenticate and deliver
individual Securities of such series of like tenor and terms in definitive form
in an aggregate principal amount equal to the principal amount of the Global
Security in exchange for such Global Security.

            (iii) If specified by the Issuer pursuant to Section 3.01 with
respect to Securities issued or issuable in the form of a Global Security, the
Depositary for such Global Security may surrender such Global Security in
exchange in whole or in part for individual Securities of such series of like
tenor and terms in definitive form on such terms as are acceptable to the Issuer
and such Depositary. Thereupon the Issuer shall execute, and the Trustee shall
authenticate and deliver, without service charge, (1) to each Person specified
by such Depositary a new Security or Securities of the same series of like tenor
and terms and of any authorized denomination of $1,000 and any integral multiple
thereof as requested by such Person in aggregate principal amount equal to and
in exchange for such Person's beneficial interest in the Global Security; and
(2) to such Depositary a new Global Security of like tenor and terms and in a
denomination equal to the difference, if any, between the principal amount of
the surrendered Global Security and the aggregate principal amount of Securities
delivered to Holders thereof.

            (iv) In any exchange provided for in any of the preceding three
paragraphs, the Issuer will execute and the Trustee will authenticate and
deliver individual Securities in definitive registered form in author-

<PAGE>
                                      -12-

ized denominations of $1,000 and any integral multiple thereof. Upon the
exchange of a Global Security for individual Securities, such Global Security
shall be cancelled by the Trustee. Securities issued in exchange for a Global
Security pursuant to this Section 2.03 shall be registered in such names and in
such authorized denominations as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee. The Trustee shall deliver such Securities to the
persons in whose names such Securities are so registered.

to the issuance of Securities of any series,

            (1) any limit upon the aggregate principal amount of the Securities
      of the series which may be authenticated and delivered under this

Section 3.03 EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

            The Securities shall be executed as a deed on behalf of the Company
by any two of the following individuals: its chairman of the Board of Directors,
a vice chairman, its president, Treasurer, Secretary or any of its vice
presidents. The signature of any of these individuals on the Securities may be
manual or facsimile.

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

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 2.01 and 3.01, or by one or more indentures supplemental hereto as
provided by Section 9.01, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be
fully protected in relying upon, an Opinion of Counsel stating,

            (a) that such form has been established in conformity with the
      provisions of this Indenture;

            (b) that such terms have been established in conformity with the
      provisions of this Indenture;

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

<PAGE>
                                      -15-

      other laws of general applicability relating to or affecting the
      enforcement of creditors' rights and to general equity principles;

            (d) that all laws and requirements in respect of the execution and
      delivery by the Company of the Securities have been complied with; and

            (e) such other matters as the Trustee may reasonably request.

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

            Each Security shall be dated the date of its authentication unless
otherwise provided by the terms established and contemplated by Section 3.01.

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

Section 3.04 TEMPORARY SECURITIES.

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

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

Section 3.05 REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

            The Company shall cause to be kept at one of its offices or agencies
maintained pursuant to Section 10.02 or at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "SECURITY REGISTER") in which, subject to
Section 2.03 and to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities.
The Trustee initially is hereby appointed "Security Registrar" for the purpose
of registering Securities and transfers of Securi-

<PAGE>
                                      -16-

ties as herein provided. The Company may act as Security Registrar and may
change or appoint a Security Registrar without prior notice to Holders or to the
Trustee.

            Subject to Section 2.03, upon surrender for registration of transfer
of any Security of any series at the office or agency in a Place of Payment for
that series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.

            Subject to Section 2.03, at the option of the Holder, Securities of
any series may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

            Subject to Section 2.03, all Securities issued upon any registration
or transfer or exchange of Securities shall be valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or
exchange.

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

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 2.03, 3.04, 9.06 or 11.07 not involving any
transfer.

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

            Each Holder of a Security agrees to indemnify the Company and the
Trustee against any liability that may result from the transfer, exchange or
assignment of such Holder's Security in violation of any provision of this
Indenture and/or applicable United States federal or state securities law.

            The Trustee shall have no obligation or duty to monitor, determine
or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security (including any transfers between or among depositary
participants or beneficial owners of interests in any Global Security) other
than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly
required by the terms of, this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

            Neither the Trustee nor any agent shall have any responsibility for
any actions taken or not taken by the Depositary.

Section 3.06 MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

            If there shall be delivered to the Company and the Trustee (i)(A)
any mutilated Security or (B) 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 hold 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 written request the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security or in exchange for such mutilated
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

            In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

            Upon the issuance of any new Security under this Section 3.06, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

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

            The provisions of this Section 3.06 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.07 PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

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

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

            (1) The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of business
      on a Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security of such series and the date of the proposed payment, and
      at the same time the Company shall deposit with the Trustee an amount of
      money equal to the aggregate amount proposed to be paid in respect of such
      Defaulted Interest or shall make arrangements satisfactory to the Trustee
      for such deposit prior to the date of the proposed payment, such money
      when deposited to be held in trust for the benefit of the Persons entitled
      to such Defaulted Interest as in this clause provided. Thereupon the
      Trustee shall fix a Special Record Date for the payment of such Defaulted
      Interest which shall be not more than 15 days and not less than 10 days
      prior to the date of the proposed payment and not less than 10 days after
      the receipt by the Trustee of the notice of the pro-

<PAGE>
                                      -18-

      posed payment. The Trustee shall promptly notify the Company of such
      Special Record Date and, in the name and at the expense of the Company,
      shall cause notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor to be mailed, first-class postage
      prepaid, to each Holder of Securities of such series at his address as it
      appears in the Security Register, not less than 10 days prior to such
      Special Record Date. Notice of the proposed payment of such Defaulted
      Interest and the Special Record Date therefor having been so mailed, such
      Defaulted Interest shall be paid to the Persons in whose names the
      Securities of such series (or their respective Predecessor Securities) are
      registered at the close of business on such Special Record Date and shall
      no longer be payable pursuant to the following clause (2).

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

            Subject to the foregoing provisions of this Section 3.07, each
Security lawfully delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

Section 3.08 PERSONS DEEMED OWNERS.

            Subject to Section 2.03, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 3.07) interest on
such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and none of the Company, the Trustee or any agent of the
Company or the Trustee shall be affected by notice to the contrary.

Section 3.09 CANCELLATION.

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

Section 3.10 COMPUTATION OF INTEREST.

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

Section 3.11 CUSIP NUMBERS.

            The Company in issuing the Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; PROVIDED that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on

<PAGE>
                                      -19-

the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee in writing of any change in the
"CUSIP" numbers.

(1) of this Section 4.01, the obligations of the Trustee under Section 4.02 and
the next to last paragraph of Section 10.03, shall survive.

Section 4.02 APPLICATION OF TRUST FUNDS; INDEMNIFICATION.

Section 4.03 or 4.04 and all money received by the Trustee in respect of U.S.
Government Obligations deposited with the Trustee pursuant to Section 4.03 or

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

premium, if any) and interest for whose payment such money has been deposited
with or received by the Trustee or to make mandatory sinking fund payments or
analogous payments as contemplated by Section 4.03 or 4.04, but such money need

accountants expressed in a written certification thereof delivered to the
Trustee, are then in excess of the amount thereof which then would have been
required to be deposited for the purpose for which such obligations or money
were deposited or received.

      of the Holders of the Securities, (i) money in dollars in an amount (or if
      the Securities are denominated in any currency other than dollars, an
      amount of the applicable currency), or (ii) U.S. Government Obligations
      which through the payment of interest and principal in respect thereof in
      accordance with their terms will provide not later than one day before the
      due date of any payment referred to in clause (A) or (B) of this
      subparagraph money in an amount, or (iii) a combination thereof,
      sufficient, in the opinion of a nationally recognized investment banking
      firm or firm of independent certified public accountants expressed in a
      written certification thereof delivered to the Trustee, to pay and
      discharge (A) the principal of (and premium, if any) and each installment

      mandatory sinking fund payments applicable to the Securities on the day on
      which such payments are due and payable in accordance with the terms of

            (e) such deposit shall not cause the Trustee with respect to the
      Securities to have a conflicting interest for purposes of the Trust
      Indenture Act with respect to the Securities;

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

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

            (h) the Company has delivered to the Trustee an Officers'
      Certificate as to solvency and the absence of any intent of preferring the
      Holders over any other creditors of the Company; and

      4.03 is to be made on or prior to one year from the Stated Maturity for
      payment of principal of the Outstanding Securities, the Company has
      delivered to the Trustee an Opinion of Counsel with no material
      qualifications or a favorable ruling of the Internal Revenue Service, in
      either case to the effect that Holders of the Securities will not
      recognize income, gain or loss for federal income tax purposes as a result
      of such deposit, defeasance and discharge and will be subject to federal
      income tax on the same amount and in the same manner and at the same
      times, as would have been the case if such deposit, defeasance and
      discharge had not occurred.

Section 4.04 DEFEASANCE OF CERTAIN OBLIGATIONS.

            If this Section 4.04 is specified to be applicable to Securities of
any series, the Company may omit to comply with any term, provision or condition
set forth in the sections of this Indenture or such Security with respect to the
Securities of that series ("COVENANT DEFEASANCE") if:

            (1) with reference to this Section 4.04, the Company has deposited
      or caused to be irrevocably deposited with the Trustee as trust funds in
      trust, specifically pledged as security for, and dedicated solely to, the
      benefit of the Holders of the Securities of that series, (i) money in
      dollars in an amount (or if the Securities are denominated in any currency
      other than dollars, an amount of the applicable currency), or (ii) U.S.
      Government Obligations which through the payment of interest and principal
      in respect thereof in accordance with their terms will provide not later
      than one day before the due date of any payment referred to in clause (A)
      or (B) of this subparagraph money in an amount, or (iii) a combination
      thereof, sufficient, in the opinion of a nationally recognized investment
      banking firm or firm of independent certified public accountants expressed
      in a written certification thereof delivered to the Trustee, to pay and
      discharge (A) the principal of (and premium, if any) and each installment
      of principal (and premium, if any) and interest on the Outstanding
      Securities of that series on the Stated Maturity of such principal or
      installment of principal or interest and (B) any mandatory sinking fund
      payments or analogous payments applicable to Securities of such series on
      the day on which such payments are due and payable in accordance with the
      terms of this Indenture and of such Securities;

            (2) such deposit shall not cause the Trustee with respect to the
      Securities of that series to have a conflicting interest for purposes of
      the Trust Indenture Act with respect to the Securities of any series;

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

            (4) the Company has delivered to the Trustee an Officers'
      Certificate as to solvency and the absence of any intent of preferring the
      Holders over any other creditors of the Company;

            (5) if the deposit referred to in subparagraph (1) of this Section
      4.04 is to be made on or prior to one year from the Stated Maturity for
      payment of principal of the Outstanding Securities, the Company has
      delivered to the Trustee an Opinion of Counsel with no material
      qualifications or a favorable ruling of the Internal Revenue Service, in
      either case to the effect that Holders of the Securities will not
      recognize income, gain or loss for federal income tax purposes as a result
      of such deposit and defeasance of certain obligations and will be subject
      to federal income tax on the same amount and in the same manner and at the
      same times, as would have been the case if such deposit and defeasance had
      not occurred; and

            (6) 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 defeasance contemplated by
      this Section 4.04 have been complied with.

            In the event the Company effects Covenant Defeasance with respect to
any Securities and such Securities are declared due and payable because of the
occurrence of any Event of Default, other than an Event of Default with respect
to any covenant as to which there has been Covenant Defeasance, the U.S.
Government Obligations on deposit with the Trustee will be sufficient to pay
amounts due on such Securities at the time of

<PAGE>
                                      -23-

the Stated Maturity but may not be sufficient to pay amounts due on such
Securities at the time of the acceleration resulting from such Event of Default.

      similar official of the Company or of any substantial part of its
      property, or ordering the winding up or liquidation of its affairs, and

      relief under any applicable bankruptcy, insolvency or other similar law or
      the taking of corporate action by the Company in furtherance of any such
      action; or

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

Section 5.02 ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

            If an Event of Default (other than an Event of Default resulting
from bankruptcy, insolvency or reorganization) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
the Securities of that series are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
of all of the Securities of that series to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified amount) shall
become immediately due and payable.

            In the case of an Event of Default resulting from bankruptcy,
insolvency or reorganization, which occurs and is continuing with respect to
Securities of any series at the time Outstanding, then all unpaid principal of
and accrued interest on all such Outstanding Securities of that series shall
become immediately due and payable without any notice or other action on the
part of the Trustee or the Holders of any Securities of such series.

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

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

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

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

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

                  (D) all sums paid or advanced by the Trustee and any
            predecessor Trustee hereunder and all sums due the Trustee and any
            predecessor Trustee under Section 6.07;

<PAGE>
                                      -25-

      and

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

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

Section 5.03 COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

            The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
or rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including all amounts due the Trustee and any predecessor Trustee
under Section 6.07.

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

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

Section 5.04 TRUSTEE MAY FILE PROOFS OF CLAIM.

            In case of 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:

            (i) to file and prove a claim for the whole amount of principal (and
      premium, if any) and interest owing and unpaid in respect of the
      Securities and to file such other papers or documents as may

<PAGE>
                                      -26-

      be necessary or advisable in order to have the claims of the Trustee
      (including any claim for the reasonable compensation, expenses,
      disbursements and advances of the Trustee, its agents and counsel) and of
      the Holders allowed in such judicial proceeding, and

            (ii) to collect and receive any moneys or other property payable or
      deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07.

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

Section 5.05 TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

            All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

Section 5.06 APPLICATION OF MONEY COLLECTED.

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

            FIRST: To the payment of all amounts due the Trustee and each
      predecessor Trustee under Section 6.07;

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

            THIRD: To the Company.

Section 5.07 LIMITATION ON SUITS.

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

<PAGE>
                                      -27-

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders (it being further understood that the Trustee does not have an
affirmative duty to ascertain whether or not such actions or forbearances are
unduly prejudicial to such Holders), or to obtain or to seek to obtain priority
or preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

Section 5.08 UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
INTEREST.

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

Section 5.09 RESTORATION OF RIGHTS AND REMEDIES.

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

Section 5.10 RIGHTS AND REMEDIES CUMULATIVE.

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

Section 5.11 DELAY OR OMISSION NOT WAIVER.

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

Section 5.12 CONTROL BY HOLDERS.

            The Holders of a majority in principal amount of the Outstanding
Securities of any series (or if more than one series is affected thereby, of all
series so affected, voting as a single class) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, PROVIDED that

            (1) such direction shall not be in conflict with any rule of law or
      with this Indenture, expose the Trustee to personal liability or be unduly
      prejudicial to holders not joining therein, and

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

            Nothing in this Indenture shall impair the right of the Trustee to
take any other action deemed proper by the Trustee which is not inconsistent
with such direction.

Section 5.13 WAIVER OF PAST DEFAULTS.

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

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

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

            Upon any such waiver, such default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

Section 5.14 UNDERTAKING FOR COSTS.

            All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section 5.14 shall not apply to any suit instituted by
the Company, to any suit instituted by the Trustee, to any suit instituted by
any Holder, or group of Holders,

<PAGE>
                                      -29-

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 for the
enforcement of the payment of the principal of (or premium, if any) or interest
on any Securities on or after the Stated Maturity or Maturities expressed in
such Security (or, in the case of redemption, on or after the Redemption Date).
This Section 5.14 shall be in lieu of Section 315(e) of the TIA and such Section
315(e) is hereby expressly excluded from this Indenture, as permitted by the
TIA.

Section 5.15 WAIVER OF STAY OR EXTENSION LAWS.

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

                                   ARTICLE SIX

                                   THE TRUSTEE

Section 6.01 CERTAIN DUTIES AND RESPONSIBILITIES.

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

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

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

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

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

<PAGE>
                                      -30-

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

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

            (4) no provision of this Indenture shall require the Trustee to
      expend or risk its own funds or otherwise incur any 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 6.01.

Section 6.02 NOTICE OF DEFAULTS.

            Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; PROVIDED, HOWEVER, that,
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Holders of Securities of
such series; and PROVIDED, FURTHER, that in the case of any default of the
character specified in Section 5.01(4) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section 6.02, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

Section 6.03 CERTAIN RIGHTS OF TRUSTEE.

            Subject to the provisions of Section 6.01:

      shall deem it desirable that a matter be proved or established prior to

      bad faith on its part, rely upon an Officers' Certificate;

            (d) the Trustee may consult with counsel of its selection and the
      advice of such counsel or any Opinion of Counsel shall be full and
      complete authorization and protection in respect of any action taken,

      satisfactory to it 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

      instrument, opinion, report, notice, request, direction, consent, order,
      bond, debenture, note, other evidence of indebtedness or other paper or
      document, but the Trustee, in its discretion, may make such further
      inquiry or investigation into such facts or matters as it may see fit,
      and, if the Trustee shall determine to make such further inquiry or
      investigation, it shall be entitled to examine the books, records and
      premises of the Company, personally or by agent or attorney and shall
      incur no liability or additional liability of any kind by reason of such
      inquiry or investigation;

            (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) in no event shall the Trustee be responsible or liable for
      special, indirect, or consequential loss or damage of any kind whatsoever
      (including, but not limited to, loss of profit) irrespective of whether
      the Trustee has been advised of the likelihood of such loss or damage and
      regardless of the form of action;

            (i) the Trustee shall not be deemed to have notice of any default or
      Event of Default unless a Responsible Officer of the Trustee has actual
      knowledge thereof or unless written notice of any event which is in fact
      such a default is received by the Trustee at the Corporate Trust Office of
      the Trustee, and such notice references the Securities and this Indenture;

      Person employed to act hereunder; and

            (k) the Trustee may request that the Company deliver an Officers'

            The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of

Indenture or of the Securities. The Trustee shall not be accountable for the use
or application by the Company of Securities or the proceeds thereof.

Section 6.05 MAY HOLD SECURITIES.

            The Trustee, any 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 6.08 and 6.12, may
otherwise deal with, and collect obligations owed to it by, the Company with the
same rights it would have if it were not Trustee, Paying Agent, Security
Registrar or such other agent.

Section 6.06 MONEY HELD IN TRUST.

            Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be

Section 6.07 COMPENSATION AND REIMBURSEMENT.

            The Company agrees

            (1) to pay to the Trustee from time to time such compensation as the
      Company and the Trustee shall from time to time agree in writing 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);

            (2) except as otherwise expressly provided herein, to reimburse each
      of the Trustee and any predecessor Trustee upon its request for all
      reasonable expenses, disbursements and advances incurred or made by it 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 own negligence or bad faith; and

            (3) to indemnify each of the Trustee and any predecessor Trustee
      for, and to hold it harmless against, any loss, liability or expense,
      arising out of or in connection with the acceptance or administration of
      the trust or trusts hereunder and the performance of its duties hereunder,
      including the costs and expenses of defending itself against any claim
      (whether asserted by the Company, a Holder or any other Person) or
      liability in connection with the exercise or performance of any of its
      powers or duties hereunder, except to the extent any such loss, liability
      or expense is due to its own negligence or bad faith.

            To ensure the performance of the obligations of the Company under
this Section 6.07, the Trustee shall have a senior claim to which the Securities
are hereby made subordinate upon all property and funds held or collected by the
Trustee as such, except property and funds held in trust for the payment of
principal of, premium, if any, or interest on particular Securities.

<PAGE>
                                      -33-

            When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.01, the expenses (including the
reasonable charges and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
applicable federal or state bankruptcy, insolvency or other similar law.

            The provisions of this Section 6.07 shall survive the termination of
this Indenture.

Section 6.08 DISQUALIFICATION; CONFLICTING INTERESTS.

            The Trustee shall comply with the terms of Section 3.10(b) of the
Trust Indenture Act.

Section 6.09 CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

            There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers having (or, in the case of the
subsidiary of a bank holding company that guarantees the obligations of the
Trustee under this Indenture, such holding company's parent shall have) a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by federal or state authority. If such corporation or holding
company parent publishes reports of condition at least annually, pursuant to law
or the requirements of said supervising or examining authority, then for the
purposes of this Section 6.09, the combined capital and surplus of such
corporation or holding company parent 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 6.09, it shall resign immediately in the manner and
with the effect hereinafter specified in this article.

Section 6.10 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

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

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

            (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 an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 days after the giving of such
notice of removal, the Trustee being removed may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

<PAGE>
                                      -34-

            (e) If at any time:

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

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

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

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

            (f) The Company also may remove the Trustee with or without cause if
the Company so notifies the Trustee thirty days in advance and if no Default
occurs or is continuing during the thirty-day period.

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

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

Section 6.11 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

            (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section 6.11, as the case may be.

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

Section 6.12 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

            Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee (including the administration of this Indenture), 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

such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

Section 6.13 PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

            If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

Section 7.01 COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

            The Company will furnish or cause to be furnished to the Trustee
with respect to the Securities of each series

            (a) semi-annually, not more than fifteen days after each Regular
      Record Date, or, in the case of any series of Securities on which
      semi-annual interest is not payable, not more than fifteen days after such
      semi-annual dates as may be specified by the Trustee, a list, in such form
      as the Trustee may reasonably require, of the names and addresses of the
      Holders as of such Regular Record Date or such semi-annual date, as the
      case may be, 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 need be furnished.

Section 7.02 PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

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

            (b) If three or more Holders (herein referred to as "APPLICANTS")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Security 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 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 7.02(a), or

<PAGE>
                                      -37-

            (ii) inform such applicants as to the approximate number of Holders
      whose names and addresses appear in the information preserved at the time
      by the Trustee in accordance with Section 7.02(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 the written request of such
applicants, mail to each Holder whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 7.02(a) a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

            (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 7.02(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 7.02(b).

            (d) Subject to Sections 7.02(a), 7.02(b), 7.02(c) and 6.01, if the
Company or any other person (other than the Trustee) shall desire to communicate
with Holders of Securities to solicit or obtain from them any proxy, consent,
authorization, waiver, approval of a plan of reorganization, arrangement or
readjustment or other action ("HOLDER ACTION"), the Trustee shall have no duty
to participate in such communication or solicitation or the processing of
responses in any manner except (i) to furnish the rules and regulations and to
perform the functions referred to in Section 1.04 and (ii) to receive (A) the
instruments evidencing the Holder Action together with (B) the Officers'
Certificate and Opinion of Counsel referred to below. The Company hereby
covenants that any and all communications and solicitations distributed by it in
connection with any Holder Action will comply in all material respects with
applicable law, including, without limitation, applicable law concerning
adequacy of disclosure. The Trustee shall have no responsibility for the
accuracy or completeness of any materials circulated to solicit any Holder
Action or for any related communications or for the compliance thereof with
applicable law. No Holder Action shall become effective until the Trustee shall
have received from the Company or other person who solicited the Holder Action
(1) the instruments evidencing such Holder Action (2) (x) (in the case of Holder
Action solicited by the Company or the representative of the Company's estate if
the Company is the debtor in any bankruptcy or other insolvency proceeding) an
Officers' Certificate and (y) (in all cases) an Opinion of Counsel, each
specifying the Holder Action taken and stating that such Holder Action has been
duly and validly taken in compliance with this Indenture in all material
respects. Such Officers' Certificate, if any, shall also certify that (after
giving effect to such Holder Action) no Event of Default or event or condition
which, with notice or lapse of time or both, would become an Event of Default
has occurred and is continuing or has not been waived.

            (e) The Depositary may grant proxies and otherwise authorize its
participants which own the Global Securities to give or take any Act which a
Holder is entitled to take under this Indenture; PROVIDED, HOWEVER, that the
Depositary has delivered a list of such participants to the Trustee.

Section 7.03 REPORTS BY TRUSTEE.

            (a) Within 60 days after September 30 of each year commencing with
the first September 30 following the date of this Indenture, the Trustee shall
transmit by mail to all Holders, as their names and addresses appear in the
Security Register, a brief report dated as of such September 30, to the extent
required by Section 3.13(a) of the Trust Indenture Act.

            (b) The Trustee shall comply with Sections 3.13(b) and 3.13(c) of
the Trust Indenture Act.

            (c) A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with the Commission and with
the Company. The Company will promptly notify the Trustee in writing when any
Securities are listed on any stock exchange, or of any delisting thereof.

Section 7.04 REPORTS BY COMPANY.

            The Company shall:

            (1) file with the Trustee, within 15 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 Commission pursuant to Section 13 or Section 15(d) of the
      Securities Exchange Act of 1934; or, if the Company is not required to
      file information, documents or reports pursuant to either of said
      sections, then it shall file with the Trustee and the Commission, in
      accordance with rules and regulations prescribed from time to time by the
      Commission, such of the supplementary and periodic information, documents
      and reports which may be required pursuant to Section 13 of the Securities
      Exchange Act of 1934 in respect of a security listed and registered on a
      national securities exchange as may be prescribed from time to time in
      such rules and regulations; and

            (2) file with the Trustee and the Commission, in accordance with the
      rules and regulations prescribed from time to time by the Commission, such
      additional 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.

            Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

Subsidiary), permit any person (other than a Subsidiary) to consolidate with or
merge into the Company, or permit any person (other than a Subsidiary) to

            (1) either (a) the Company shall be the surviving person or (b) the
      person (if other than the Company) formed by such consolidation or into
      which the Company is merged or the person which acquires by conveyance,
      transfer or lease the properties and assets of the Company substantially
      as an entirety is an entity organized and existing under the laws of the

      which is, on the date of this Indenture, a member of the Organisation for
      Economic Co-operation and Development or the European Union and shall
      expressly assume, by an indenture supplemental hereto, executed and
      delivered to the Trustee, in form reasonably satisfactory to the Trustee,
      all of the obligations of the Company under the Securities and this
      Indenture;

            (2) immediately after giving effect to such transaction, no Event of
      Default, and no event that, after notice or lapse of time or both, would
      become an Event of Default, shall have occurred and be continuing; and

            (3) the Company shall have delivered to the Trustee an Officers'
      Certificate stating that such consolidation, merger, conveyance, transfer,
      sale or lease and, if a supplemental indenture is required in connection
      with such transaction, such supplemental indenture, comply with this

and the successor person shall enter into a supplemental indenture to evidence
the succession and substitution of such successor person and such discharge and
release of the Company.

<PAGE>
                                      -40-

long as such changes, other than those in clause (2), do not materially and
adversely affect the interests of the Holder:

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

            (2) to make any modifications or amendments that do not, in the good
      faith opinion of the Company's Board of Directors and the Trustee,
      adversely affect the interests of the Holders in any material respect;

            (3) to provide for the assumption of the Company's obligations under
      this Indenture by a successor upon any merger, consolidation or asset
      transfer as permitted by and in compliance with Article Eight of this

            (7) to make any change necessary for the registration of the
      Securities under the Securities Act or to comply with the TIA, or any
      amendment thereto, or to comply with any requirement of the Commission in

      affect the interests of the Holders of the Securities in any material
      respect; or

            (8) to provide for uncertificated Securities in addition to or in
      place of certificated Securities or to provide for bearer Securities; or

      and with or without interest coupons; or

            (10) to change or eliminate any of the provisions of this Indenture,
      PROVIDED that any such change or elimination shall become effective only
      when there is no Security Outstanding of any series created prior to the
      execution of such supplemental indenture which is entitled to the benefit
      of such provision; or

            (11) to establish the form or terms of Securities of any series as

Section 9.02 AMENDMENTS OR SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

            With the written consent of the Holders of not less than a majority

series affected by such amendment or supplement (taken

<PAGE>
                                      -41-

together as one class), the Company, when authorized by a Board Resolution, and
the Trustee, at any time and from time to time, may amend or supplement this
Indenture or the Securities. However, without the consent of each Holder
affected, an amendment to this Indenture or the Securities may not:

            (1) change the Stated Maturity of the principal of, or premium, if
      any, or any installment of interest with respect to the Securities;

            (2) reduce the principal amount of, or the rate of interest on, or

            (8) modify or change any provision of this Indenture or the related
      definitions affecting the ranking of the Securities in any manner which
      adversely affects the Holders; and

            (9) modify the foregoing requirements or reduce the percentage of
      Outstanding Securities necessary to waive any covenant or past default.

            It shall not be necessary for any Act of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment or
supplemental indenture, but it shall be sufficient if such Act approves the
substance thereof.

            After an amendment or supplemental indenture under this Section 9.02
becomes effective, the Company shall mail to each Holder a notice briefly
describing the amendment or supplemental indenture.

            An amendment or 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.

Section 9.03 EXECUTION OF SUPPLEMENTAL INDENTURES.

            The Trustee shall sign any supplemental indenture authorized
pursuant to this article if the amendment contained therein does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does,
the Trustee may, but need not, sign such supplemental indenture. In executing,
or accepting the additional trusts created by, any supplemental indenture
permitted by this article or the modifications thereby of the trusts created by
this Indenture, the Trustee shall receive, and (subject to Section 6.01) shall
be fully protected in

<PAGE>
                                      -42-

relying upon, an Officers' Certificate and an Opinion of Counsel stating that
the execution of such supplemental indenture is authorized or permitted by this
Indenture.

Section 9.04 EFFECT OF SUPPLEMENTAL INDENTURES.

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

Section 9.05 CONFORMITY WITH TRUST INDENTURE ACT.

            Every supplemental indenture executed pursuant to this article shall

            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.

                                   ARTICLE TEN

                                    COVENANTS

Section 10.01 PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

            The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture. At the option of the Company,
payment of principal (and premium, if any) and interest may be made by wire
transfer or (subject to collection) by check mailed to the address of the Person
entitled thereto at such address as shall appear in the Security Register.

Section 10.02 MAINTENANCE OF OFFICE OR AGENCY.

            The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for 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 hereby initially appoints the Trustee
its office or agency for each of said purposes. 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.

<PAGE>
                                      -43-

            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.

Section 10.03 MONEY FOR SECURITIES; PAYMENTS TO BE HELD IN TRUST.

            If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and 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 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 10.03, that such Paying Agent will:

            (1) hold all sums held by it for the payment on 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;

            (2) 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

            (3) 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 trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of (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

<PAGE>
                                      -44-

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, shall at the expense of the Company cause
to be mailed or published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation
in the City, County and State of New York, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such mailing or publication, any unclaimed balance of
such money then remaining will be repaid to the Company.

                            REDEMPTION OF SECURITIES

Section 11.01 APPLICABILITY OF ARTICLE.

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

Section 11.02 ELECTION TO REDEEM; NOTICE TO TRUSTEE.

            The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company shall, at
least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed, such notice to be accompanied by a written statement signed by an
authorized officer of the Company stating that no defaults in the payment of
interest or Events of Default with respect to the Securities of that series have
occurred (which have not been waived or cured). In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee an Officers' Certificate evidencing compliance
with such restriction.

Section 11.03 SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

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

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

<PAGE>
                                      -46-

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

Section 11.04 NOTICE OF REDEMPTION.

            Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 45 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not such
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to any such Holder in respect of any Security, shall not affect the
validity of the proceedings for the redemption of any other Security.

            All notices of redemption shall state:

            (1) the Redemption Date,

            (2) the Redemption Price and any accrued interest,

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

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

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

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

            (7) the CUSIP number and, if applicable, the ISIN number, of the
      Securities being 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 written request,
by the Trustee in the name and at the expense of the Company.

Section 11.05 DEPOSIT OF REDEMPTION PRICE.

            On or prior to 10:00 a.m., New York City time, on any Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.03) an amount of money, in funds immediately available on
the due date, sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

                                      -47-

Section 11.06 SECURITIES PAYABLE ON REDEMPTION DATE.

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

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

            The Trustee shall not redeem any Securities of any series pursuant
to this article (unless all Outstanding Securities of such series are to be
redeemed) or mail or give any notice of redemption of Securities during the
continuance of an Event of Default hereunder known to the Trustee with respect
to such series, except that, where the mailing of notice of redemption of any
Securities shall theretofore have been made, the Trustee shall redeem or cause
to be redeemed such Securities, PROVIDED that it shall have received from the
Company a sum sufficient for such redemption. Except as aforesaid, any moneys
theretofore or thereafter received by the Trustee shall, during the continuance
of such Event of Default, be deemed to have been collected under Article Five
and held for the payment of all such Securities of such series. In case such
Event of Default shall have been waived as provided in Section 5.13 or the
default cured on or before the sixtieth day preceding the Redemption Date, such
moneys shall thereafter be applied in accordance with the provisions of this
article.

Section 11.07 SECURITIES REDEEMED IN PART.

            Any Security which is to be redeemed only in part shall be
surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Security or Securities of the same series, 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.

Section 11.08 PURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON A CHANGE IN
CONTROL.

            (a) If a Change in Control occurs, the Securities shall be purchased
by the Company, at the option of the Holder thereof, at the purchase price
specified in the subject Securities on the Change in Control Purchase Date (the
"CHANGE IN CONTROL PURCHASE PRICE"), as of the date that is 45 days after the
date of the Change in Control Purchase Notice (as defined below in Section
11.08(c)) delivered by the Company (the "CHANGE IN CONTROL PURCHASE DATE"),
subject to satisfaction by or on behalf of the Holder of the requirements set
forth in Section 11.08(c).

            Subject to conditions specified in the subject Securities, a "CHANGE
IN CONTROL" shall be deemed to have occurred at such time after the Securities
are originally issued as either of the following events shall occur:

<PAGE>
                                      -48-

            (i) any person, including any syndicate or group deemed to be a
      "person" under Section 13(d)(3) of the Exchange Act, acquires beneficial
      ownership, directly or indirectly, through a purchase, merger or other
      acquisition transaction or series of transactions, of shares of the
      Company's Capital Stock entitling the person to exercise 50% or more of
      the total voting power of all shares of the Company's Capital Stock that
      are entitled to vote generally in elections of directors, other than an
      acquisition by the Company, any of its Subsidiaries or any of its employee
      benefit plans and other than any transaction contemplated by clause
      (a)(ii)(B) of this Section 11.08; or

            (ii) the Company merges or consolidates with or into any other
      person (other than a Subsidiary), any merger of another person (other than
      a Subsidiary) into the Company, or the Company conveys, sells, transfers
      or leases all or substantially all of its assets to another person (other
      than a Subsidiary), other than any transaction: (A) that does not result
      in any reclassification, conversion, exchange or cancellation of the
      Company's outstanding Ordinary Shares (other than the cancellation of any
      of the Company's outstanding Ordinary Shares held by the person with whom
      the Company merges or consolidates), or (B) pursuant to which the holders
      of the Company's Ordinary Shares immediately prior to the transaction have
      the entitlement to exercise, directly or indirectly, 50% or more of the
      total voting power of all shares of Capital Stock entitled to vote
      generally in the election of directors of the continuing or surviving
      corporation immediately after the transaction, or (C) which is effected
      solely to change the Company's jurisdiction of incorporation and results
      in a reclassification, conversion or exchange of outstanding Ordinary
      Shares solely into shares of common stock of the surviving entity.

            However, a Change in Control will not be deemed to have occurred if

Shares of the Company, the closing price for the Company's outstanding Ordinary
Shares for any five trading days within the period of 10 consecutive trading
days ending immediately after the later of the Change in Control or the public
announcement of the Change in Control, in the case of a Change in Control
relating to an acquisition of Capital Stock, or the period of 10 consecutive
trading days ending immediately before the Change in Control, in the case of a
Change in Control relating to a merger, consolidation or asset sale, equals or
exceeds 105% of the average of the closing prices for such convertible debt
securities on each of such trading days or (B) all of the consideration
(excluding cash payments for fractional shares and cash payments made pursuant
to dissenters' appraisal rights) in a merger or consolidation otherwise
constituting a Change in Control under clause (i) and/or clause (ii) above
consists of shares of common stock traded on a national securities exchange or
quoted on the Nasdaq National Market (or will be so traded or quoted immediately
following the merger or consolidation).

            At least three Business Days before the Change in Control Notice
Date (as defined below), the Company shall deliver an Officers' Certificate to
the Trustee specifying:

            (i) the manner of payment selected by the Company;

            (ii) the information required by Section 11.08(b);

            (iii) the form of consideration to be used to pay the Change in
      Control Purchase Price and, if such consideration is not cash, that the
      conditions to such manner of payment set forth in this Indenture and the
      supplemental indenture hereto governing such Securities have been or will
      be complied with; and

            (iv) whether the Company desires the Trustee to give the Change in
      Control Notice required by Section 11.08(b).

<PAGE>
                                      -49-

            (b) No later than 30 days after the occurrence of a Change in
Control, the Company shall mail a written notice of the Change in Control (the
"CHANGE IN CONTROL NOTICE," the date of such mailing, the "CHANGE IN CONTROL
NOTICE DATE") by first-class mail to the Trustee and to each Holder (and to
beneficial owners as required by applicable law). The notice shall include a
form of Change in Control Purchase Notice to be completed by the Holder and
shall state:

            (1) briefly, the nature of the Change in Control and the date of
      such Change in Control;

            (2) the date by which the Change in Control Purchase Notice pursuant

            (6) if applicable, the then existing conversion rate and any
      adjustments thereto;

            (7) that the Securities must be surrendered to the Paying Agent to
      collect payment;

            (8) that the Change in Control Purchase Price for any Security as to
      which a Change in Control Purchase Notice has been duly given and not
      withdrawn will be paid promptly following the later of the Change in
      Control Purchase Date and the time of surrender of such Security as
      described in (7);

            (9) briefly, the procedures the Holder must follow to exercise
      rights under this Section 11.08;

            (11) the procedures for withdrawing a Change in Control Purchase
      Notice;

            (12) that, unless the Company defaults in making payment of such
      Change in Control Purchase Price, interest, if any, on Securities
      surrendered for purchase by the Company will cease to accrue on and after
      the Change in Control Purchase Date; and

            (13) the CUSIP number(s) and, if applicable, the ISIN number(s), of
      the Securities.

            Notice of redemption of Securities to be redeemed shall be given by
the Trustee in the name and at the expense of the Company.

            (c) A Holder may exercise its rights specified in Section 11.08(a)
upon delivery of a written notice of purchase (a "CHANGE IN CONTROL PURCHASE
NOTICE") to the Paying Agent at any time on or prior to the 30th day after the
date the Company delivers its written Change in Control Purchase Notice,
stating:

            (1) the certificate number of the Security which the Holder will
      deliver to be purchased;

            (2) the portion of the principal amount of the Security which the
      Holder will deliver to be purchased, which portion must be $1,000 or an
      integral multiple thereof; and

<PAGE>
                                      -50-

            (3) that such Security shall be purchased pursuant to the terms and
      conditions specified in the Securities.

            The delivery of such Security to the Paying Agent with the Change in
Control Purchase Notice (together with all necessary endorsements) at the
offices of the Paying Agent shall be a condition to the receipt by the Holder of
the Change in Control Purchase Price therefor; PROVIDED, HOWEVER, that such
Change in Control Purchase Price shall be so paid pursuant to this Section 11.08
only if the Security so delivered to the Paying Agent shall conform in all
material respects to the description thereof set forth in the related Change in
Control Purchase Notice.

            The Company shall purchase from the Holder thereof, pursuant to this
Section 11.08, a portion of a Security if the principal amount at maturity of
such portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

            Any purchase by the Company contemplated pursuant to the provisions
of this Section 11.08 shall be consummated by the delivery of the consideration
to be received by the Holder on the Change of Control Purchase Date.

            (d) PROCEDURE UPON PURCHASE. The Company shall deposit the
consideration to be received by the Holder specified in Section 11.08 at the
time and in the manner as provided in Section 11.10, sufficient to pay the
aggregate Change in Control Purchase Price of all Securities to be purchased
pursuant to this Section 11.08.

            (e) TAXES. If a Holder of a purchased Security is paid in Ordinary
Shares pursuant to this Section 11.08, the Company shall pay all, stamp and
other duties, if any, which may be imposed by the United States or any political
subdivision thereof or taxing authority thereof or therein with respect to the
issuance of Ordinary Shares. However, the Holder shall pay any such tax which is
due because the Holder requests the Ordinary Shares to be issued in a name other
than the Holder's name. The Paying Agent may refuse to deliver the certificates
representing the Ordinary Shares being issued in a name other than the Holder's
name until the Paying Agent receives a sum sufficient to pay any tax which will
be due because the Ordinary Shares are to be issued in a name other than the
Holder's name. Nothing herein shall preclude any income tax withholding required
by law or regulations.

Section 11.09 EFFECT OF PURCHASE NOTICE OR CHANGE IN CONTROL PURCHASE NOTICE.

            Upon receipt by the Paying Agent of the Change in Control Purchase
Notice specified in Section 11.08(c) the Holder of the Security in respect of
which such Change in Control Purchase Notice was given shall (unless such Change
in Control Purchase Notice is withdrawn as specified in the following two
paragraphs) thereafter be entitled to receive solely the Change in Control
Purchase Price with respect to such Security. Such Change in Control Purchase
Price shall be paid to such Holder, subject to receipts of funds and/or
securities by the Paying Agent, promptly following the later of (x) the Change
in Control Purchase Date with respect to such Security (provided the conditions
in Section 11.08(c) have been satisfied) and (y) the time of delivery of such
Security to the Paying Agent by the Holder thereof in the manner required by
Section 11.08(c).

            A Change in Control Purchase Notice may be withdrawn by means of a

accordance with the Change in Control Purchase Notice at any time prior to the
close of business on the last day prior to the Change in Control Purchase Date
specifying:

            (1) the certificate number of the Security in respect of which such
      notice of withdrawal is being submitted or the appropriate Depositary
      procedures if Certificated Securities have been issued,

            (2) the principal amount of the Security with respect to which such
      notice of withdrawal is being submitted, and

            (3) the principal amount, if any, of such Security which remains
      subject to the original Change in Control Purchase Notice and which has
      been or will be delivered for purchase by the Company.

Section 11.10 DEPOSIT OF CHANGE IN CONTROL PURCHASE PRICE.

            Prior to 10:00 a.m. New York City time on the Business Day following
the Change in Control Purchase Date, the Company shall deposit with the Trustee

either of them is acting as the Paying Agent, shall segregate and hold in trust
as provided in Section 10.03) an amount of cash (in immediately available funds
if deposited on such Business Day) and/or other consideration, if permitted
hereunder, under a supplemental indenture or the Securities, sufficient to pay
the aggregate Change in Control Purchase Price of all the Securities or portions
thereof which are to be purchased as of the Change in Control Purchase Date.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

Section 12.01 APPLICABILITY OF ARTICLE.

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

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

Section 12.02 SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

            The Company (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; PROVIDED that 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.

                                      -52-

Section 12.03 REDEMPTION OF SECURITIES FOR SINKING FUND.

            Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company (1) will deliver to the Trustee an
Officers' Certificate (A) stating that no defaults in the payment of interest or
Events of Default with respect to Securities of that series have occurred (which
have not been waived or cured), (B) specifying the amount of the next ensuing
sinking fund payment for that series pursuant to the terms of Securities of that
series, (C) stating whether or not the Company intends to exercise its right, if
any, to make an optional sinking fund payment with respect to such series on the
next ensuing sinking fund payment date and, if so, specifying the amount of such
optional sinking fund payment and (D) specifying the portion of such sinking
fund payment, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 12.02 and (2) will also deliver to
the Trustee any Securities to be so delivered. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities of such
series to be redeemed upon such sinking fund payment date in the manner
specified in Section 11.03 and cause notice of the redemption thereof to be
given in the name of and at the expense of the Company in the manner provided in
Section 11.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
11.05, 11.06 and 11.07. Failure of the Company, on or before any such 60th day,
to deliver such Officers' Certificate and Securities specified in this Section
12.03, if any, shall not constitute a default but shall constitute, on and as of
such date, the irrevocable election of the Company (a) that the mandatory
sinking fund payment for such series due on the next succeeding sinking fund
payment date shall be paid entirely in cash without the option to deliver or
credit Securities of such series in respect thereof and (b) that the Company
will make no optional sinking fund payment with respect to Securities of such
series as provided in this article.

            The Trustee shall not redeem or cause to be redeemed any Security of
a series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
with respect to such series except that, where the mailing of notice of
redemption of any Securities shall therefore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, PROVIDED that it shall have
received from the Company a sum sufficient for such redemption. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur, and any moneys thereafter paid
into the sinking fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and held for the
payment of all such Securities of such series. In case such Event of Default
shall have been waived as provided in Section 5.13 or the default cured on or
before the 60th day preceding the sinking fund payment date, such moneys shall
thereafter be applied on the next succeeding sinking fund payment date in
accordance with this Section 12.03 to the redemption of such Securities.

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

            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

SECTION 1.04. ACTS OF HOLDERS.

            (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this

            (d) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a Board Resolution, fix in advance
a record date for the determination of Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Notwithstanding Trust Indenture Act
Section 3.16(c), such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not earlier than the
date 30 days prior to the first solicitation of Holders generally in connection
therewith and not later than the date such solicitation is completed. If such a
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act maybe given before or after such record date, but
only the Holders 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 shall be computed as of such
record date; PROVIDED, HOWEVER, that no such authorization, agreement or consent
by such Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than
eleven months after the record date.

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

SECTION 1.05. NOTICES, ETC., TO TRUSTEE AND COMPANY.

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

            (1) the Trustee by any Holder or by the Company shall be sufficient
      for every purpose hereunder if made, given, furnished or filed in writing
      (including a facsimile transmission) to or with the Trustee at its
      Corporate Trust Office, Attention: Corporate Trust Administration, or

            (2) the Company by the Trustee or by any Holder shall be sufficient
      for every purpose hereunder (unless otherwise herein expressly provided)
      if in writing (including a facsimile transmission) and mailed, first-class
      postage prepaid, to the Company addressed to it at the address of its
      principal office

                                      -7-

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

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

SECTION 1.07. CONFLICT WITH TRUST INDENTURE ACT.

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

are for convenience only and shall not affect the construction hereof.

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

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

SECTION 1.11. BENEFITS OF INDENTURE.

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

SECTION 1.12. GOVERNING LAW; WAIVER OF JURY TRIAL.

            This Indenture and the Securities shall be governed by and construed
in accordance with the laws of the State of New York, and for all purposes will
be construed in accordance with the laws of said State without giving effect to
principles of conflicts of laws of such State.

                                      -8-

            EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE
NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

SECTION 1.13. LEGAL HOLIDAYS.

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

SECTION 1.14. REFERENCES TO CURRENCY.

            All references in this Indenture to "dollars" or "$" are to the
currency of the United States of America.

SECTION 1.15. FORCE MAJEURE.

            In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of
or caused by, directly or indirectly, forces beyond its control, including,
without limitation, strikes, work stoppages, accidents, acts of war or
terrorism, civil or military disturbances, nuclear or natural catastrophes or
acts of God, and interruptions, loss or malfunctions of utilities,
communications or computer (software and hardware) services; it being understood
that the Trustee shall use reasonable efforts which are consistent with accepted
practices in the banking industry to resume performance as soon as practicable
under the circumstances.

the Trustee shall, in accordance with Section 3.03 and the Company Order
delivered to the Trustee thereunder, authenticate and deliver, such Global
Security or Securities, which (i) shall represent, and shall be denominated in
an amount equal to the aggregate principal amount of, the Outstanding Securities
of such series to be represented by such Global Security or Securities, (ii)
shall be registered in the name of the Depositary for such Global Security or
Securities or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or its custodian or pursuant to the 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 THE INDIVIDUAL SECURITIES REPRESENTED
HEREBY, THIS GLOBAL SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE (I) BY THE
DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR (II) BY A NOMINEE OF THE DEPOSITARY
OR THE DEPOSITARY 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."

            (b) Notwithstanding any other provision of this Section 2.03 or of
Section 3.05, unless the terms of a Global Security expressly permit such Global
Security to be exchanged in whole or in part for individual Securities, a Global
Security may be transferred, in whole but not in part and in the manner provided
in Section 3.05, only to another nominee of the Depositary for such Global
Security, or to a successor Depositary for such Global Security selected or
approved by the Issuer or to a nominee of such successor Depositary.

            (c) (i) If at any time the Depositary for a Global Security notifies
the Issuer that it is unwilling or unable to continue as Depositary for such
Global Security or if at any time the Depositary for the Securities for such
series shall no longer be eligible or in good standing under the Securities
Exchange Act of 1934, as amended, or other applicable statute or regulation, the
Issuer shall appoint a successor Depositary with respect to such Global
Security. If a successor Depositary for such Global Security is not appointed by
the Issuer within 90 days after the Issuer receives such notice or becomes aware
of such ineligibility, the Issuer will execute a Company Order for the
authentication and delivery of individual Securities of such series in exchange
for such Global Security, and the Trustee, upon receipt of such Company Order,
will authenticate and deliver individual Securities of

                                      -10-
<PAGE>

such series of like tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of the Global Security in exchange for such
Global Security.

            (ii) If an Event of Default shall have occurred and be continuing or
an event shall have occurred which with the giving of notice or lapse of time or
both, would constitute an Event of Default with respect to the Securities
represented by such Global Security, the Trustee, upon receipt of a Company
Order for the authentication and delivery of individual Securities of such
series in exchange for such Global Security, will authenticate and deliver
individual Securities of such series of like tenor and terms in definitive form
in an aggregate principal amount equal to the principal amount of the Global
Security in exchange for such Global Security.

            (iii) If specified by the Issuer pursuant to Section 3.01 with
respect to Securities issued or issuable in the form of a Global Security, the
Depositary for such Global Security may surrender such Global Security in
exchange in whole or in part for individual Securities of such series of like
tenor and terms in definitive form on such terms as are acceptable to the Issuer
and such Depositary. Thereupon the Issuer shall execute, and the Trustee shall
authenticate and deliver, without service charge, (1) to each Person specified
by such Depositary a new Security or Securities of the same series of like tenor
and terms and of any authorized denomination of $1,000 and any integral multiple
thereof as requested by such Person in aggregate principal amount equal to and
in exchange for such Person's beneficial interest in the Global Security; and
(2) to such Depositary a new Global Security of like tenor and terms and in a
denomination equal to the difference, if any, between the principal amount of
the surrendered Global Security and the aggregate principal amount of Securities
delivered to Holders thereof.

            (iv) In any exchange provided for in any of the preceding three
paragraphs, the Issuer will execute and the Trustee will authenticate and
deliver individual Securities in definitive registered form in authorized
denominations of $1,000 and any integral multiple thereof. Upon the exchange of
a Global Security for individual Securities, such Global Security shall be
cancelled by the Trustee. Securities issued in exchange for a Global Security
pursuant to this Section 2.03 shall be registered in such names and in such
authorized denominations as the Depositary for such Global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the persons
in whose names such Securities are so registered.

                                  ARTICLE III.

to such Board Resolution and set forth in such Officers' Certificate or in any
such indenture supplemental hereto.

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

SECTION 3.02. DENOMINATIONS.

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

SECTION 3.03. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

            The Securities shall be executed as a deed on behalf of the Company
by any two of the following individuals: its chairman of the Board of Directors,
a vice chairman, its president, Treasurer, Secretary or any of its vice
presidents. The signature of any of these officers on the Securities may be
manual or facsimile.

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

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 2.01 and 3.01, or by one or more indentures supplemental hereto as
provided by Section 9.01, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be
fully protected in relying upon, an Opinion of Counsel stating,

                                      -13-
<PAGE>

            (a) that such form has been established in conformity with the
      provisions of this Indenture;

            (b) that such terms have been established in conformity with the
      provisions of this Indenture;

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

            (d) that all laws and requirements in respect of the execution and
      delivery by the Company of the Securities have been complied with; and

            (e) such other matters as the Trustee may reasonably request.

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

            Each Security shall be dated the date of its authentication unless
otherwise provided by the terms established and contemplated by Section 3.01.

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

SECTION 3.04. TEMPORARY SECURITIES.

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

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

SECTION 3.05. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

            The Company shall cause to be kept at one of its offices or agencies
maintained pursuant to Section 10.02 or at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "SECURITY REGISTER") in which, subject to
Section 2.03 and to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities.
The Trustee initially is

                                      -14-
<PAGE>

hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided. The Company may act as Security
Registrar and may change or appoint a Security Registrar without prior notice to
Holders or to the Trustee.

            Subject to Section 2.03, upon surrender for registration of transfer
of any Security of any series at the office or agency in a Place of Payment for
that series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.

            Subject to Section 2.03, at the option of the Holder, Securities of
any series may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

            Subject to Section 2.03, all Securities issued upon any registration
or transfer or exchange of Securities shall be valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or
exchange.

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

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 2.03, 3.04, 9.06 or 11.07 not involving any
transfer.

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

            Each Holder of a Security agrees to indemnify the Company and the
Trustee against any liability that may result from the transfer, exchange or
assignment of such Holder's Security in violation of any provision of this
Indenture and/or applicable United States federal or state securities law.

            The Trustee shall have no obligation or duty to monitor, determine
or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security (including any transfers between or among depositary
participants or beneficial owners of interests in any Global Security) other
than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly
required by the terms of, this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

            Neither the Trustee nor any Agent shall have any responsibility for
any actions taken or not taken by the Depositary.

SECTION 3.06. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

            If there shall be delivered to the Company and the Trustee (i)(A)
any mutilated Security or (B) 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 hold 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

                                      -15-
<PAGE>

execute and upon its written request the Trustee shall authenticate and deliver,
in lieu of any such destroyed, lost or stolen Security or in exchange for such
mutilated Security, a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

            In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

            Upon the issuance of any new Security under this Section 3.06, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

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

            The provisions of this Section 3.06 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.07. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

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

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

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

            (2) The Company may make payment of any Defaulted Interest on the
      Securities of any series in any other lawful manner not inconsistent with
      the requirements of any securities exchange on which such Securities may
      be listed, and upon such notice as may be required by such exchange, if,
      after notice

                                      -16-
<PAGE>

      given by the Company to the Trustee of the proposed payment pursuant to
      this clause, such manner of payment shall be deemed practicable by the
      Trustee.

            Subject to the foregoing provisions of this Section 3.07, each
Security lawfully delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

SECTION 3.08. PERSONS DEEMED OWNERS.

            Subject to Section 2.03, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 3.07) interest on
such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and none of the Company, the Trustee or any agent of the
Company or the Trustee shall be affected by notice to the contrary.

SECTION 3.09. CANCELLATION.

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

SECTION 3.10. COMPUTATION OF INTEREST.

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

SECTION 3.11. CUSIP NUMBERS.

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

                  (ii) U.S. Government Obligations which through the payment of
                  interest and principal in respect thereof in accordance with
                  their terms will provide not later than one day before the due

                  thereof delivered to the Trustee, (A) 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 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;

            Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 6.07, and, if money
shall have been deposited with the Trustee pursuant to Subclause (B) of clause
(1) of this Section 4.01, the obligations of the Trustee under Section 4.02 and
the next to last paragraph of Section 10.03, shall survive.

SECTION 4.02. APPLICATION OF TRUST FUNDS; INDEMNIFICATION.

            (a) Subject to the provisions of the last paragraph of Section

principal (and premium, if any) and interest for whose payment such money has
been deposited with or received by the Trustee or to make mandatory sinking fund

accountants expressed in a written certification thereof delivered to the
Trustee, are then in excess of the amount thereof which then would have been
required to be deposited for the purpose for which such obligations or money
were deposited or received.

the deposit referred to in subparagraph (d) of this Section 4.03, and the
provisions of this Indenture, as it relates to such Outstanding Securities,

      6.07,

PROVIDED that, the following conditions shall have been satisfied:

            (d) the Company has or caused to be irrevocably deposited (except as
      provided in Section 4.02) with the Trustee as trust funds in trust,
      specifically pledged as security for, and dedicated solely to, the benefit
      of the Holders of the Securities, (i) money in dollars in an amount (or if
      the Securities are denominated in any currency other than dollars, an
      amount of the applicable currency), or (ii) U.S. Government Obligations
      which through the payment of interest and principal in respect thereof in
      accordance with their terms will provide not later than one day before the

      subparagraph money in an amount, or (iii) a combination thereof,
      sufficient, in the opinion of a nationally recognized investment banking

      Securities to have a conflicting interest for purposes of the Trust
      Indenture Act with respect to the Securities;

                                      -19-
<PAGE>

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

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

            (h) the Company has delivered to the Trustee an Officers'
      Certificate as to solvency and the absence of any intent of preferring the
      Holders over any other creditors of the Company; and

            (i) if the deposit referred to in subparagraph (d) of this Section
      4.03 is to be made on or prior to one year from the Stated Maturity for
      payment of principal of the Outstanding Securities, the Company has
      delivered to the Trustee an Opinion of Counsel with no material
      qualifications or a favorable ruling of the Internal Revenue Service, in
      either case to the effect that Holders of the Securities will not
      recognize income, gain or loss for federal income tax purposes as a result
      of such deposit, defeasance and discharge and will be subject to federal
      income tax on the same amount and in the same manner and at the same
      times, as would have been the case if such deposit, defeasance and
      discharge had not occurred.

SECTION 4.04. DEFEASANCE OF CERTAIN OBLIGATIONS.

            If this Section 4.04 is specified to be applicable to Securities of
any series, the Company may omit to comply with any term, provision or condition
set forth in the sections of this Indenture or such Security with respect to the
Securities of that series ("COVENANT DEFEASANCE") if:

            (1) with reference to this Section 4.04, the Company has deposited
      or caused to be irrevocably deposited with the Trustee as trust funds in
      trust, specifically pledged as security for, and dedicated solely to, the
      benefit of the Holders of the Securities of that series, (i) money in
      dollars in an amount (or if the Securities are denominated in any currency
      other than dollars, an amount of the applicable currency), or (ii) U.S.
      Government Obligations which through the payment of interest and principal
      in respect thereof in accordance with their terms will provide not later
      than one day before the due date of any payment referred to in clause (A)
      or (B) of this subparagraph money in an amount, or (iii) a combination
      thereof, sufficient, in the opinion of a nationally recognized investment
      banking firm or firm of independent certified public accountants expressed
      in a written certification thereof delivered to the Trustee, to pay and
      discharge (A) the principal of (and premium, if any) and each installment
      of principal (and premium, if any) and interest on the Outstanding
      Securities of that series on the Stated Maturity of such principal or
      installment of principal or interest and (B) any mandatory sinking fund
      payments or analogous payments applicable to Securities of such series on
      the day on which such payments are due and payable in accordance with the
      terms of this Indenture and of such Securities;

            (2) such deposit shall not cause the Trustee with respect to the
      Securities of that series to have a conflicting interest for purposes of
      the Trust Indenture Act with respect to the Securities of any series;

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

            (4) if the deposit referred to in subparagraph (1) of this Section
      4.04 is to be made on or prior to one year from the Stated Maturity for
      payment of principal of the Outstanding Securities, the Company has
      delivered to the Trustee an Opinion of Counsel with no material
      qualifications or a favorable ruling of the Internal Revenue Service, in
      either case to the effect that Holders of the Securities will not
      recognize income, gain or loss for federal income tax purposes as a result
      of such deposit and defeasance of certain obligations and will be subject
      to federal income tax on the same amount and in the same manner and at the
      same times, as would have been the case if such deposit and defeasance had
      not occurred;

      Certificate as to solvency and the absence of any intent of preferring the
      Holders over any other creditors of the Company; and

      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent herein provided for relating to the defeasance contemplated by
      this Section 4.04 have been complied with.

            In the event the Company effects Covenant Defeasance with respect to
any Securities and such Securities are declared due and payable because of the
occurrence of any Event of Default, other than an Event of Default with respect
to any covenant as to which there has been Covenant Defeasance, the U.S.
Government Obligations on deposit with the Trustee will be sufficient to pay
amounts due on such Securities at the time of the Stated Maturity but may not be
sufficient to pay amounts due on such Securities at the time of the acceleration
resulting from such Event of Default.

                                   ARTICLE V.

                                    REMEDIES

      custodian, receiver, liquidator, assignee, trustee, sequestrator or other
      similar official of the Company or of any substantial part of its
      property, or ordering the winding up or liquidation of its affairs, and

      by it of an assignment for the benefit of creditors, or the admission by
      it in writing of its inability to pay its debts generally as they become
      due and its willingness to have a case commenced against it or to seek an
      order for relief under any applicable bankruptcy, insolvency or other
      similar law or the taking of corporate action by the Company in
      furtherance of any such action; or

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

SECTION 5.02. ACCELERATION OF MATURITY: RESCISSION AND ANNULMENT.

            If an Event of Default (other than an Event of Default resulting
from bankruptcy, insolvency or reorganization) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
the Securities of that series are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
of all of the Securities of that series to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified amount) shall
become immediately due and payable.

            In the case of an Event of Default resulting from bankruptcy,
insolvency or reorganization, which occurs and is continuing with respect to
Securities of any series at the time Outstanding, then all unpaid principal of
and accrued interest on all such Outstanding Securities of that series shall
become immediately due and payable without any notice or other action on the
part of the Trustee or the Holders of any Securities of such series.

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

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

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

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

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

                  (D) all sums paid or advanced by the Trustee and any
            predecessor Trustee hereunder and all sums due the Trustee and any
            predecessor Trustee under Section 6.07;

      and

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

                                      -22-
<PAGE>

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

SECTION 5.03. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

            The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
or rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including all amounts due the Trustee and any predecessor Trustee
under Section 6.07.

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

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

SECTION 5.04. TRUSTEE MAY FILE PROOFS OF CLAIM.

            In case of 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,

            (i) to file and prove a claim for the whole amount of principal (and
      premium, if any) and interest owing and unpaid in respect of the

Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07.

respect of the claim of any Holder in any such proceeding.

SECTION 5.05. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

            All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 5.06. APPLICATION OF MONEY COLLECTED.

            Any money collected by the Trustee pursuant to this article shall be
applied in the following order, at the date or dates fixed by the Trustee and,

      any) and interest, respectively; and

            THIRD: To the Company.

SECTION 5.07. LIMITATION ON SUITS.

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

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

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

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

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

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

                                      -24-
<PAGE>

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders (it being further understood that the Trustee does not have an
affirmative duty to ascertain whether or not such actions or forbearances are
unduly prejudicial to such Holders), or to obtain or to seek to obtain priority
or preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

SECTION 5.08. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
INTEREST.

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

SECTION 5.09. RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 5.10. RIGHTS AND REMEDIES CUMULATIVE.

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

SECTION 5.11. DELAY OR OMISSION NOT WAIVER.

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

SECTION 5.12. CONTROL BY HOLDERS.

            The Holders of a majority in principal amount of the Outstanding
Securities of any series (or if more than one series is affected thereby, of all
series so affected, voting as a single class) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, PROVIDED that

            (1) such direction shall not be in conflict with any rule of law or
      with this Indenture, expose the Trustee to personal liability or be unduly
      prejudicial to holders not joining therein, and

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

                                      -25-
<PAGE>

            Nothing in this Indenture shall impair the right of the Trustee to
take any other action deemed proper by the Trustee which is not inconsistent
with such direction.

SECTION 5.13. WAIVER OF PAST DEFAULTS.

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

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

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

            Upon any such waiver, such default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 5.14. UNDERTAKING FOR COSTS.

            All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section 5.14 shall not apply to any suit instituted by
the Company, to any suit instituted by the Trustee, to any suit instituted by
any Holder, or group of Holders, holding in the aggregate more than 10% in
principal amount of the Outstanding Securities of any series, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of
(or premium, if any) or interest on any Securities on or after the Stated
Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date). This Section 5.14 shall be in lieu
of Section 3.15(e) of the TIA and such Section 3.15(e) is hereby expressly
excluded from this Indenture, as permitted by the TIA.

SECTION 5.15. WAIVER OF STAY OR EXTENSION LAWS.

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

                                   ARTICLE VI.

                                   THE TRUSTEE

SECTION 6.01. CERTAIN DUTIES AND RESPONSIBILITIES.

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

                                      -26-
<PAGE>

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

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

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

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

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

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

            (4) no provision of this Indenture shall require the Trustee to
      expend or risk its own funds or otherwise incur any 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 6.01.

SECTION 6.02. NOTICE OF DEFAULTS.

            Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; PROVIDED, HOWEVER, that,
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Holders of Securities of
such series; and PROVIDED, FURTHER, that in the case of any default of the
character specified in Section 5.01(4) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section 6.02, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

      other evidence be herein specifically prescribed) may, in the absence of
      bad faith on its part, rely upon an Officers' Certificate;

            (d) the Trustee may consult with counsel of its selection and the

      investigation, it shall be entitled to examine the books, records and
      premises of the Company, personally or by agent or attorney and shall
      incur no liability or additional liability of any kind by reason of such
      inquiry or investigation;

      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

            (h) in no event shall the Trustee be responsible or liable for
      special, indirect, or consequential loss or damage of any kind whatsoever
      (including, but not limited to, loss of profit) irrespective of whether
      the Trustee has been advised of the likelihood of such loss or damage and
      regardless of the form of action;

            (i) the Trustee shall not be deemed to have notice of any Default or
      Event of Default unless a Responsible Officer of the Trustee has actual
      knowledge thereof or unless written notice of any event which is in fact
      such a default is received by the Trustee at the Corporate Trust Office of
      the Trustee, and such notice references the Securities and this Indenture;

      specified as so authorized in any such certificate previously delivered
      and not superseded.

SECTION 6.04. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

            The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee 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 shall not be accountable for the use
or application by the Company of Securities or the proceeds thereof.

SECTION 6.05. MAY HOLD SECURITIES.

            The Trustee, any 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 6.08 and 6.12, may

Registrar or such other agent.

SECTION 6.06. MONEY HELD IN TRUST.

SECTION 6.07. COMPENSATION AND REIMBURSEMENT.

            The Company agrees:

            (1) to pay to the Trustee from time to time such compensation as the
      Company and the Trustee shall from time to time agree in writing 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);

            (2) except as otherwise expressly provided herein, to reimburse each
      of the Trustee and any predecessor Trustee upon its request for all
      reasonable expenses, disbursements and advances incurred or made by it 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 own negligence or bad faith; and

            (3) to indemnify each of the Trustee and any predecessor Trustee
      for, and to hold it harmless against, any loss, liability or expense,
      arising out of or in connection with the acceptance or administration of
      the trust or trusts hereunder and the performance of its duties hereunder,
      including the costs and expenses of defending itself against any claim
      (whether asserted by the Company, a Holder or any other person) or
      liability in connection with the exercise or performance of any of its
      powers or duties hereunder, except to the extent any such loss, liability
      or expense is due to its own negligence or bad faith.

            To ensure the performance of the obligations of the Company under
this Section 6.07, the Trustee shall have a senior claim to which the Securities
are hereby made subordinate upon all property and funds held or collected by the
Trustee as such, except property and funds held in trust for the payment of
principal of, premium, if any, or interest on particular Securities.

            When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.01, the expenses (including the
reasonable charges and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
applicable federal or state bankruptcy, insolvency or other similar law.

                                      -29-
<PAGE>

            The provisions of this Section 6.07 shall survive the termination of
this Indenture.

SECTION 6.08. DISQUALIFICATION; CONFLICTING INTERESTS.

            The Trustee shall comply with the terms of Section 3.10(b) of the
Trust Indenture Act.

SECTION 6.09. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

            There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers having (or, in the case of the
subsidiary of a bank holding company that guarantees the obligations of the
Trustee under this Indenture, such holding company's parent shall have) a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by federal or state authority. If such corporation or holding
company parent publishes reports of condition at least annually, pursuant to law
or the requirements of said supervising or examining authority, then for the
purposes of this Section 6.09, the combined capital and surplus of such
corporation or holding company parent 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 6.09, it shall resign immediately in the manner and
with the effect hereinafter specified in this article.

SECTION 6.10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

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

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

            (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 an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 days after the giving of such
notice of removal, the Trustee being removed may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

            (e) If at any time:

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

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

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

                                      -30-
<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 who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

            (f) The Company also may remove the Trustee with or without cause if
the Company so notifies the Trustee thirty days in advance and if no Default
occurs or is continuing during the thirty-day period.

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

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

SECTION 6.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

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

                                      -31-
<PAGE>

trusts hereunder administered by any other such Trustee; and upon the execution
and delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein and each
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates; but, on request of the Company or
any successor Trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section 6.11, as the case may be.

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

SECTION 6.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

            Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee (including the administration of this Indenture), 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.

            If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor). A trustee who has resigned or been
removed shall be subject to the Trust Indenture Act Section 3.11(a) to the
extent provided therein.

                                  ARTICLE VII.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 7.01. COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

            The Company will furnish or cause to be furnished to the Trustee
with respect to the Securities of each series

            (a) semi-annually, not more than fifteen days after each Regular
      Record Date, or, in the case of any series of Securities on which
      semi-annual interest is not payable, not more than fifteen days after such
      semi-annual dates as may be specified by the Trustee, a list, in such form
      as the Trustee may reasonably require, of the names and addresses of the
      Holders as of such Regular Record Date or such semi-annual date, as the
      case may be, 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;

                                      -32-
<PAGE>

PROVIDED, HOWEVER, that so long as the Trustee is the Security Registrar, no
such list need be furnished.

SECTION 7.02. PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

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

            (b) If three or more Holders (herein referred to as "APPLICANTS")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Security 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 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 7.02(a), or

            (ii) inform such applicants as to the approximate number of Holders
      whose names and addresses appear in the information preserved at the time
      by the Trustee in accordance with Section 7.02(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 the written request of such
applicants, mail to each Holder whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 7.02(a) a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

            (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 7.02(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 7.02(b).

            (d) Subject to Sections 7.02(a), 7.02(b), 7.02(c) and 6.01, if the
Company or any other person (other than the Trustee) shall desire to communicate
with Holders of Securities to solicit or obtain from them any proxy, consent,
authorization, waiver, approval of a plan of reorganization, arrangement or
readjustment or other action ("HOLDER ACTION"), the Trustee shall have no duty
to participate in such communication or solicitation or the processing of
responses in any manner except (i) to furnish the rules and regulations and to
perform the functions referred to in Section 1.04 and (ii) to receive (A) the
instruments evidencing the Holder Action together with (B) the Officers'
Certificate and Opinion of Counsel referred to below. The Company hereby
covenants that any and all communications and solicitations distributed by it in
connection with any Holder Action will comply in all material respects with
applicable law, including, without limitation, applicable law concerning
adequacy of disclosure. The

                                      -33-
<PAGE>

Trustee shall have no responsibility for the accuracy or completeness of any
materials circulated to solicit any Holder Action or for any related
communications or for the compliance thereof with applicable law. No Holder
Action shall become effective until the Trustee shall have received from the
Company or other person who solicited the Holder Action (1) the instruments
evidencing such Holder Action (2) (x) (in the case of Holder Action solicited by
the Company or the representative of the Company's estate if the Company is the
debtor in any bankruptcy or other insolvency proceeding) an Officers'
Certificate and (y) (in all cases) an Opinion of Counsel, each specifying the
Holder Action taken and stating that such Holder Action has been duly and
validly taken in compliance with this Indenture in all material respects. Such
Officers' Certificate, if any, shall also certify that (after giving effect to
such Holder Action) no Event of Default or event or condition which, with notice
or lapse of time or both, would become an Event of Default has occurred and is
continuing or has not been waived.

            (e) The Depositary may grant proxies and otherwise authorize its
participants which own the Global Securities to give or take any Act which a
Holder is entitled to take under this Indenture; PROVIDED, however, that the
Depositary has delivered a list of such participants to the Trustee.

SECTION 7.03. REPORTS BY TRUSTEE.

            (a) Within 60 days after September 30 of each year commencing with
the first September 30 following the date of this Indenture, the Trustee shall
transmit by mail to all Holders, as their names and addresses appear in the
Security Register, a brief report dated as of such September 30, to the extent
required by Section 3.13(a) of the Trust Indenture Act.

            (b) The Trustee shall comply with Sections 3.13(b) and 3.13(c) of
the Trust Indenture Act.

            (c) A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with the Commission and with
the Company. The Company will promptly notify the Trustee in writing when any
Securities are listed on any stock exchange or of any delisting thereof.

SECTION 7.04. REPORTS BY COMPANY.

            The Company shall:

            (1) file with the Trustee, within 15 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 Commission pursuant to Section 13 or Section 15(d) of the
      Securities Exchange Act of 1934; or, if the Company is not required to
      file information, documents or reports pursuant to either of said
      sections, then it shall file with the Trustee and the Commission, in
      accordance with rules and regulations prescribed from time to time by the
      Commission, such of the supplementary and periodic information, documents
      and reports which may be required pursuant to Section 13 of the Securities
      Exchange Act of 1934 in respect of a security listed and registered on a
      national securities exchange as may be prescribed from time to time in
      such rules and regulations; and

            (2) file with the Trustee and the Commission, in accordance with the
      rules and regulations prescribed from time to time by the Commission, such
      additional 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.

            Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

Subsidiary), permit any person (other than a Subsidiary) to consolidate with or
merge into the Company, or permit any person (other than a Subsidiary) to
convey, transfer, sell or lease that person's properties and assets

            (1) either (a) the Company shall be the surviving person or (b) the
      person (if other than the Company) formed by such consolidation or into
      which the Company is merged or the person which acquires by conveyance,
      transfer or lease the properties and assets of the Company substantially
      as an entirety is an entity organized and existing under the laws of the
      United States of America (including any State thereof or the District of

      which is, on the date of this Indenture, a member of the Organisation for
      Economic Co-operation and Development or the European Union and shall
      expressly assume, by an indenture supplemental hereto, executed and
      delivered to the Trustee, in form reasonably satisfactory to the Trustee,
      all of the obligations of the Company under the Securities and this
      Indenture;

            (2) immediately after giving effect to such transaction, no Event of
      Default, and no event that, after notice or lapse of time or both, would

Indenture and the Securities. Subject to Section 9.03, the Company, the Trustee
and the successor person shall enter into a supplemental indenture to evidence

than those in clause (2), do not materially and adversely affect the interests
of the Holder:

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

                                      -35-
<PAGE>

            (2) to make any modifications or amendments that do not, in the good

            (7) to make any change necessary for the registration of the
      Securities under the Securities Act or to comply with the TIA, or any
      amendment thereto, or to comply with any requirement of the Commission in

      affect the interests of the Holders of the Securities in any material
      respect; or

            (8) to provide for uncertificated Securities in addition to or in

      and with or without interest coupons; or

            (10) to change or eliminate any of the provisions of this Indenture,
      PROVIDED that any such change or elimination shall become effective only
      when there is no Security Outstanding of any series created prior to the
      execution of such supplemental indenture which is entitled to the benefit
      of such provision; or

            (11) to establish the form or terms of Securities of any series as

SECTION 9.02. AMENDMENTS OR SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

            With the written consent of the Holders of not less than a majority
in aggregate principal amount of the Securities at the time Outstanding of all
series affected by such amendment or supplement (taken together as one class),
the Company, when authorized by a Board Resolution, and the Trustee, at any time

      on, or any installment of interest with respect to the Securities;

            (2) reduce the principal amount of, or the rate of interest on, or
      any premium payable upon the redemption of, the Securities;

      convert the Securities into Ordinary Shares in accordance with the
      provisions of this Indenture.

            It shall not be necessary for any Act of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment or
supplemental indenture, but it shall be sufficient if such Act approves the
substance thereof.

            After an amendment or supplemental indenture under this Section 9.02
becomes effective, the Company shall mail to each Holder a notice briefly
describing the amendment or supplemental indenture.

            An amendment or 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.

SECTION 9.03. EXECUTION OF SUPPLEMENTAL INDENTURES.

            The Trustee shall sign any supplemental indenture authorized
pursuant to this article if the amendment contained therein does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does,
the Trustee may, but need not, sign such supplemental indenture. In executing,
or accepting the additional trusts created by, any supplemental indenture
permitted by this article or the modifications thereby of the trusts created by
this Indenture, the Trustee shall receive, and (subject to Section 6.01) shall
be fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel stating that the execution of such supplemental indenture is authorized
or permitted by this Indenture.

SECTION 9.04. EFFECT OF SUPPLEMENTAL INDENTURES.

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

SECTION 9.06. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

                                   ARTICLE X.

                                    COVENANTS

SECTION 10.01. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

            The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture. At the option of the Company,
payment of principal (and premium, if any) and interest may be made by wire
transfer or (subject to collection) by check mailed to the address of the Person
entitled thereto at such address as shall appear in the Security Register.

SECTION 10.02. MAINTENANCE OF OFFICE OR AGENCY.

            The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for 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 hereby initially appoints the Trustee
its office or agency for each of said purposes. 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.

SECTION 10.03. MONEY FOR SECURITIES; PAYMENTS TO BE HELD IN TRUST.

            If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and 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 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.

                                      -38-
<PAGE>

            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 10.03, that such Paying Agent will:

            (1) hold all sums held by it for the payment on 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;

            (2) 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

            (3) 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 trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of (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, shall at
the expense of the Company cause to be mailed or published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in the City, County and State of New York, 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 mailing or
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

            The Company shall have no obligation to make payment of principal of
(or premium, if any) or interest on any Security in immediately available funds,
except that if the Company shall have received original payment for Securities
in immediately available funds it shall make available immediately available
funds for payment of the principal of such Securities.

SECTION 10.04. CORPORATE EXISTENCE.

            Subject to Article Eight, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; PROVIDED, HOWEVER,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

SECTION 10.05. MAINTENANCE OF PROPERTIES.

            The Company will use its reasonable efforts to cause all material
properties used or useful in the conduct of its business to be maintained and
kept in good condition, repair and working order (subject to wear and tear) and
supplied with all necessary material equipment and will use its reasonable
efforts to cause to be made all necessary material repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advan-

                                      -39-
<PAGE>

tageously conducted at all times; PROVIDED, HOWEVER, that nothing in this
Section 10.05 shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business and not disadvantageous
in any material respect to the Holders.

SECTION 10.06. STATEMENT BY OFFICERS AS TO DEFAULT.

            The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof, a
certificate of the principal executive officer, principal financial officer or
principal accounting officer of the Company stating whether or not to the best
knowledge of the signers thereof the Company is in default in the performance
and observance of any of the terms, provisions and conditions of this Indenture,
and if the Company shall be in default, specifying all such defaults and the
nature and status thereof of which they may have knowledge.

SECTION 10.07. WAIVER OF CERTAIN COVENANTS.

            The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 10.06 if before or after the
time for such compliance the Holders of at least a majority in principal amount
of the Outstanding Securities (taken together as one class) shall, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with 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.

SECTION 10.08. CALCULATION OF ORIGINAL ISSUE DISCOUNT.

            The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

                                   ARTICLE XI.

                            REDEMPTION OF SECURITIES

SECTION 11.01. APPLICABILITY OF ARTICLE.

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

SECTION 11.02. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

            The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company shall, at
least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed, such notice to be accompanied by a written statement signed by an
authorized officer of the Company stating that no defaults in the payment of
interest or Events of Default with respect to the Securities of that series have
occurred (which have not been waived or cured). In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee an Officers' Certificate evidencing compliance
with such restriction.

                                      -40-
<PAGE>

SECTION 11.03. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

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

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

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

SECTION 11.04. NOTICE OF REDEMPTION.

            Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 45 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not such
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to any such Holder in respect of any Security, shall not affect the
validity of the proceedings for the redemption of any other Security.

            All notices of redemption shall state:

            (1) the Redemption Date,

            (2) the Redemption Price and any accrued interest,

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

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

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

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

            (7) the CUSIP number and, if applicable, the ISIN number, of the
      Securities being 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 written request,
by the Trustee in the name and at the expense of the Company.

SECTION 11.05. DEPOSIT OF REDEMPTION PRICE.

            On or prior to 10:00 a.m., New York City time, on any Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and

                                      -41-
<PAGE>

hold in trust as provided in Section 10.03) an amount of money, in funds
immediately available on the due date, sufficient to pay the Redemption Price
of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date.

SECTION 11.06. SECURITIES PAYABLE ON REDEMPTION DATE.

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

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

            The Trustee shall not redeem any Securities of any series pursuant
to this article (unless all Outstanding Securities of such series are to be
redeemed) or mail or give any notice of redemption of Securities during the
continuance of an Event of Default hereunder known to the Trustee with respect
to such series, except that, where the mailing of notice of redemption of any
Securities shall theretofore have been made, the Trustee shall redeem or cause
to be redeemed such Securities, PROVIDED that it shall have received from the
Company a sum sufficient for such redemption. Except as aforesaid, any moneys
theretofore or thereafter received by the Trustee shall, during the continuance
of such Event of Default, be deemed to have been collected under Article Five
and held for the payment of all such Securities of such series. In case such
Event of Default shall have been waived as provided in Section 5.13 or the
default cured on or before the sixtieth day preceding the Redemption Date, such
moneys shall thereafter be applied in accordance with the provisions of this
article.

SECTION 11.07. SECURITIES REDEEMED IN PART.

            Any Security which is to be redeemed only in part shall be
surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Security or Securities of the same series, 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.

                                  ARTICLE XII.

                                  SINKING FUNDS

SECTION 12.01. APPLICABILITY OF ARTICLE.

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

            The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "MANDATORY SINKING
FUND PAYMENT," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "OPTIONAL
SINKING FUND PAY-

                                      -42-
<PAGE>

MENT." If provided for by the terms of Securities of any series, the cash amount
of any sinking fund payment may be subject to reduction as provided in Section
12.02. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

SECTION 12.02. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

            The Company (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; PROVIDED that 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.

SECTION 12.03. REDEMPTION OF SECURITIES FOR SINKING FUND.

            Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company (1) will deliver to the Trustee an
Officers' Certificate (A) stating that no defaults in the payment of interest or
Events of Default with respect to Securities of that series have occurred (which
have not been waived or cured), (B) specifying the amount of the next ensuing
sinking fund payment for that series pursuant to the terms of Securities of that
series, (C) stating whether or not the Company intends to exercise its right, if
any, to make an optional sinking fund payment with respect to such series on the
next ensuing sinking fund payment date and, if so, specifying the amount of such
optional sinking fund payment and (D) specifying the portion of such sinking
fund payment, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 12.02 and (2) will also deliver to
the Trustee any Securities to be so delivered. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities of such
series to be redeemed upon such sinking fund payment date in the manner
specified in Section 11.03 and cause notice of the redemption thereof to be
given in the name of and at the expense of the Company in the manner provided in
Section 11.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
11.05, 11.06 and 11.07. Failure of the Company, on or before any such 60th day,
to deliver such Officers' Certificate and Securities specified in this Section
12.03, if any, shall not constitute a default but shall constitute, on and as of
such date, the irrevocable election of the Company (a) that the mandatory
sinking fund payment for such series due on the next succeeding sinking fund
payment date shall be paid entirely in cash without the option to deliver or
credit Securities of such series in respect thereof and (b) that the Company
will make no optional sinking fund payment with respect to Securities of such
series as provided in this Article XII.

            The Trustee shall not redeem or cause to be redeemed any Security of
a series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
with respect to such series except that, where the mailing of notice of
redemption of any Securities shall therefore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, PROVIDED that it shall have
received from the Company a sum sufficient for such redemption. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur, and any moneys thereafter paid
into the sinking fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and held for the
payment of all such Securities of such series. In case such Event of Default
shall have been waived as provided in Section 5.13 or the default cured on or
before the 60th day preceding the sinking fund payment date, such moneys shall
thereafter be applied on the next succeeding sinking fund payment date in
accordance with this Section 12.03 to the redemption of such Securities.

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

                                      -43-

                                  SUBORDINATION

SECTION 13.01. AGREEMENT TO SUBORDINATE.

            (a) The Company covenants and agrees, and each Holder of Securities
issued hereunder by such Holder's acceptance thereof likewise covenants and
agrees, that (except as otherwise specified as contemplated by Section 3.01 for
Securities of any series) all Securities shall be issued subject to the
provisions of this article; and each Holder of a Security, whether upon original
issue or upon transfer or assignment thereof, accepts and agrees to be bound by
such provisions.

            (b) The payment by the Company of the principal of, and interest on,
the Securities issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to the
prior payment in full of all Senior Indebtedness of the Company, whether
outstanding at the date of this Indenture or thereafter incurred.

            (c) No provision of this article shall prevent the occurrence of any
default or Event of Default hereunder.

SECTION 13.02. DEFAULT ON SENIOR INDEBTEDNESS.

            (a) No direct or indirect payment by or on behalf of the Company of
principal of, premium, if any, or interest on the Securities, whether pursuant
to the terms of the Securities or upon acceleration, by way of repurchase,
redemption, defeasance or otherwise, will be made if, at the time of such
payment, there exists a default in the payment when due of all or any portion of
the obligations under or in respect of any Senior Indebtedness, whether at
maturity, on account of mandatory redemption or prepayment, acceleration or
otherwise, and such default shall not have been cured or waived or the benefits
of this sentence waived by or on of the holders of Senior Indebtedness.

            (b) In addition, during the continuance of any non-payment default
or non-payment event of default with respect to any Senior Indebtedness pursuant
to which the maturity thereof may be accelerated, and upon receipt by the
Trustee of written notice (a "PAYMENT BLOCKAGE NOTICE") from a holder or holders
of such Senior Indebtedness or the trustee or agent acting on behalf of such
Senior Indebtedness, then, unless and until such default or event of default has
been cured or waived or has ceased to exist or such Senior Indebtedness has been
discharged or repaid in full in cash, or the requisite holders of such Senior
Indebtedness have otherwise agreed in writing, no payment of any kind or
character with respect to any principal of or interest on or distribution will
be made by or on behalf of the Company on account of or with respect to the
Securities, during a period (a "PAYMENT BLOCKAGE PERIOD") commencing on the date
of receipt of such Payment Blockage Notice by the Trustee and ending 179 days
thereafter.

            (c) Notwithstanding anything herein to the contrary, (x) in no event
will a Payment Blockage Period extend beyond 179 days from the date the Payment
Blockage Notice in respect thereof was given and (y) there must be 180 days in
any 360-day period during which no Payment Blockage Period is in effect. Not
more than one Payment Blockage Period may be commenced with respect to the
Securities during any period of 360 consecutive days. No default or event of
default that existed or was continuing on the date of commencement of any
Payment Blockage Period with respect to the Senior Indebtedness initiating such
Payment Blockage Period may be, or be made, the basis for the commencement of
any other Payment Blockage Period by the holder or holders of such Senior
Indebtedness or the trustee or agent acting on behalf of such Senior
Indebtedness, whether or not within a period of 360 consecutive days, unless
such default or event of default has been cured or waived for a period of not
less than 90 consecutive days.

            (d) In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee when such payment is prohibited by the
preceding paragraph of this Section 13.02, such payment shall be

                                      -44-
<PAGE>

held in trust for the benefit of, and shall be paid over or delivered to, the
holders of Senior Indebtedness or their respective representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, as calculated by the Company, to the extent necessary to
pay such Senior Indebtedness in full, in cash, after giving effect to any
concurrent payment or distribution to or for the benefit of the holders of such
Senior Indebtedness, before any payment or distribution is made to the Holders
or to the Trustee.

SECTION 13.03. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

            (a) Upon any distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any total
or partial dissolution, winding-up, liquidation or reorganization of the
Company, whether voluntary or involuntary, assignment for the benefit of
creditors or marshalling of the Company's assets, or in bankruptcy, insolvency,
receivership or other similar proceedings, whether voluntary or involuntary, all
principal, premium, if any, and interest due or to become due to all Senior
Indebtedness of the Company shall first be paid in full in cash, or such payment
duly provided for to the satisfaction of the holders of the Senior Indebtedness,
before the Holders are entitled to receive or retain any payment; and upon any
such dissolution or winding-up or liquidation or reorganization, any payment by
the Company, or distribution of assets of the Company of any kind or character
whether in cash, property or securities, which the Holders or the Trustee would
be entitled to receive from the Company, except for the provisions of this
article, shall be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the Holders or by the Trustee under this Indenture if received by them or
it, directly to the holders of Senior Indebtedness of the Company or their
respective representatives, or to the trustee or trustees under any indenture
pursuant to which any instruments evidencing such Senior Indebtedness may have
been issued, as their respective interests may appear, as calculated by the
Company, to the extent necessary to pay such Senior Indebtedness in full in
cash, or such payment duly provided for to the satisfaction of the holders of
the Senior Indebtedness, after giving effect to any concurrent payment or
distribution to or for the benefit of the holders of such Senior Indebtedness,
before any payment or distribution is made to the Holders or to the Trustee.

            (b) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee before all Senior Indebtedness of the Company is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for the benefit of, and shall be
paid over or delivered to, the holders of such Senior Indebtedness or their
respective representatives, or to the trustee or trustees under any indenture
pursuant to which any instruments evidencing such Senior Indebtedness may have
been issued, as their respective interests may appear, as calculated by the
Company, to the extent necessary to pay such Senior Indebtedness in full, in
cash, after giving effect to any concurrent payment or distribution to or for
the benefit of the holders of such Senior Indebtedness, before any payment or
distribution is made to the Holders or to the Trustee.

            (c) For purposes of this article, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this article with respect to
the Securities to the payment of all Senior Indebtedness of the Company that may
at the time be outstanding; PROVIDED, HOWEVER, that (i) such Senior Indebtedness
is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (ii) the rights of the holders of such
Senior Indebtedness are not, without the consent of such holders, altered by
such reorganization or readjustment. The amalgamation or consolidation of the
Company with, or the merger of the Company into, another corporation or the
liquidation or dissolution of the Company following the conveyance or transfer
of its properties or assets substantially as an entirety, to another corporation
upon the terms and conditions provided for in Article Eight of this Indenture
shall not be deemed a dissolution, winding-up, liquidation or reorganization for
the purposes of this Section 13.03 if such other corporation shall, as part of
such amalgamation, consolidation, merger, conveyance or transfer, comply with
the conditions stated in Article Eight of this Indenture. Nothing in Section
13.02 or in this Section 13.03 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.07 of this Indenture.

                                      -45-

            (d) If the Trustee or any Holder of Securities does not file a
proper claim or proof of debt in the form required in any proceeding referred to
above prior to 30 days before the expiration of the time to file such claim in
such proceeding, then the holder of any Senior Indebtedness is hereby
authorized, and has the right, to file an appropriate claim or claims for or on
behalf of such Holder of Securities.

SECTION 13.04. SUBROGATION.

            (a) Subject to the payment in full of all Senior Indebtedness of the
Company then outstanding, the rights of the Holders shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company applicable to such
Senior Indebtedness until the principal of and interest on the Securities shall
be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of such Senior Indebtedness of any cash, property
or securities to which the Holders or the Trustee would be entitled except for
the provisions of this article, and no payment over pursuant to the provisions
of this article to or for the benefit of the holders of such Senior Indebtedness
by Holders or the Trustee, shall, as between the Company, its creditors other
than holders of Senior Indebtedness of the Company, and the Holders, be deemed
to be a payment by the Company to or on account of such Senior Indebtedness. It
is understood that the provisions of this article are and are intended solely
for the purposes of defining the relative rights of the Holders, on the one
hand, and the holders of such Senior Indebtedness, on the other hand.

            (b) Nothing contained in this Article XIII or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as between the
Company, its creditors other than the holders of Senior Indebtedness of the
Company, and the Holders, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders the principal of and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders and creditors of the Company other than the holders of Senior
Indebtedness of the Company nor shall anything herein or therein prevent the
Trustee or any Holder of Securities from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this article of the holders of such Senior Indebtedness in
respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

            (c) Upon any payment or distribution of assets of the Company
referred to in this article, the Trustee, subject to the provisions of Section
6.01 of this Indenture, and the Holders shall be entitled to rely conclusively
upon any order or decree made by any court of competent jurisdiction in which
such dissolution, winding-up, liquidation or reorganization proceedings are
pending, or a certificate of the receiver, trustee in bankruptcy, liquidation
trustee, agent or other Person making such payment or distribution, delivered to
the Trustee or the Holders, for the purposes of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior Indebtedness
and other indebtedness of the Company the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this article.

SECTION 13.05. TRUSTEE TO EFFECTUATE SUBORDINATION

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

SECTION 13.06. NOTICE BY THE COMPANY.

            (a) The Company shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Company that would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this article. Notwithstanding the
provisions of this article or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts that would
prohibit the making of any payment of monies to or by the Trustee in respect of
the Securities pursuant to the provisions of this article, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a Holder or holders of Senior Indebtedness or from any
representative or trustee therefor; and before the receipt of any such written
notice, the Trustee, subject to the provisions of Section 6.01 of this
Indenture, shall be entitled in all respects to assume that no such facts exist;
PROVIDED, HOWEVER, that if the Trustee

                                      -46-
<PAGE>

shall not have received the notice provided for in this Section 13.06 at least
two Business Days prior to the date upon which by the terms hereof any money may
become payable for any purpose (including, without limitation, the payment of
the principal of or interest on any Security), then, anything herein contained
to the contrary notwithstanding, the Trustee shall have full power and authority
to receive such money and to apply the same to the purposes for which such money
was received, and shall not be affected by any notice to the contrary that may
be received by it within two Business Days prior to such date.

            (b) The Trustee, subject to the provisions of Section 6.01 of this
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company (or a trustee or representative on behalf of such
holder), to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee or representative on behalf of any such holder or
holders. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of such
Senior Indebtedness to participate in any payment or distribution pursuant to
this article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of such Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this article and, if such evidence is not furnished,
the Trustee may defer any payment to such Person pending judicial determination
as to the right of such Person to receive such payment.

SECTION 13.07. RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

            (a) The Trustee in its individual capacity shall be entitled to all
the rights set forth in this article in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

            (b) With respect to the holders of Senior Indebtedness of the
Company, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this article and no
implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of such Senior
Indebtedness and, subject to the provisions of Section 6.01 of this Indenture,
the Trustee shall not be liable to any holder of such Senior Indebtedness if it
shall pay over or deliver to Holders, the Company or any other Person money or
assets to which any holder of such Senior Indebtedness shall be entitled by
virtue of this article or otherwise.

SECTION 13.08. SUBORDINATION MAY NOT BE IMPAIRED.

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

            (b) Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness of the Company may, at any time
and from time to time, without the consent of or notice to the Trustee or the
Holders, without incurring responsibility to the Holders and without impairing
or releasing the subordination provided in this article or the obligations
hereunder of the Holders to the holders of such Senior Indebtedness, do any one
or more of the following: (i) change the manner, place or terms of payment or
extend the time of payment of, or renew or alter, such Senior Indebtedness, or
otherwise amend or supplement in any manner such Senior Indebtedness or any
instrument evidencing the same or any agreement under which such Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing such Senior Indebtedness;
(iii) release any Person liable in any manner for the collection of such Senior
Indebtedness; and (iv) exercise or refrain from exercising or waive any rights
against the Company and any other Person.

            (c) Each present and future holder of Senior Indebtedness shall be
entitled to the benefit of the provisions of this article notwithstanding that
such holder is not a party to this Indenture.

SECTION 13.09. ARTICLE APPLICABLE TO PAYING AGENTS.

            In case at any time any Paying Agent other than the Trustee shall
have been appointed by the Company and be then acting hereunder, the term
"TRUSTEE" as used in this article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this article in addition to or in place of the Trustee; PROVIDED,
HOWEVER, that this Section 13.09 shall not apply to the Company or any Affiliate
of the Company if it or such Affiliate acts as Paying Agent.

SECTION 13.10. DEFEASANCE OF THIS ARTICLE.

            Notwithstanding anything contained herein to the contrary, payments
from cash or the proceeds of United States Government Obligations held in trust
under Article Four hereof by the Trustee (or other qualifying trustee) and which
were deposited in accordance with the terms of Article Four hereof and not in
violation of Section 13.02 hereof for the payment of principal of and interest
on the Securities shall not be subordinated to the prior payment of any Senior
Indebtedness or subject to the restrictions set forth in this article, and none
of the Holders shall be obligated to pay over any such amount to the Company or
any holder of Senior Indebtedness or any other creditor of the Company.

SECTION 13.11. SUBORDINATION LANGUAGE TO BE INCLUDED IN SECURITIES.

            Each Security shall contain a subordination provision which will be
substantially in the following form:

            "The Securities are subordinated in right of payment, in the manner
and to the extent set forth in the Indenture, to the prior payment in full of
all Senior Indebtedness (as defined in the Indenture, or as set forth in one or
more indentures supplemental hereto, a Board Resolution in accordance with
Section 3.01 of the Indenture or in this Security). Each Holder by accepting a
Security agrees to such subordination and authorizes the Trustee to give it
affect."

SECTION 13.12. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS.

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