         Section 1.2. Compliance Certificates and Opinions.
                      ------------------------------------

         Except as otherwise expressly provided in this Indenture, 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 an Opinion of Counsel stating that, in the opinion of such counsel, such
action is authorized or permitted by this Indenture and that all such conditions
precedent, if any, have been complied with, except that in the case of any such
application or request as to which the furnishing of such documents or any of
them is specifically required by any provision of this Indenture relating to
such particular application or request, no additional certificate or opinion
need be furnished.

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

                  (a) a statement that the individual signing such certificate

         Section 1.3.  Form of Documents Delivered to Trustee.
                       --------------------------------------

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

         Any certificate or opinion of an officer of the Company or the
Guarantor may be based, insofar as it relates to legal matters, upon an Opinion
of Counsel, provided that such officer, after reasonable inquiry, has no reason
to believe and does not believe that the Opinion of Counsel with respect to the
matters upon which his certificate or opinion is based is erroneous. Any such
Opinion of Counsel may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
the Company or the Guarantor stating that the information with respect to such
factual matters is in the possession of the Company or the Guarantor, as the
case may be, provided that such counsel, after reasonable inquiry, has no reason
to believe and does not believe 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 or any Security, they may, but need not, be
consolidated and form one instrument.

         Section 1.4.  Acts of Holders.
                       ---------------

         (1) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by or pursuant to 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. If, but only if, Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture or the
related Series Authorization to be given or taken by Holders of Securities of
such series may, alternatively, be embodied in and evidenced by the record of
Holders of Securities of such series voting in favor thereof, either in person
or by proxies duly appointed in writing, at any meeting of Holders of Securities
of such series duly called and held in accordance with the provisions of Article
15, or a combination of such instruments and any such record. Except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments or record or both are received by a Responsible
Officer of the Trustee and, where it is hereby expressly required, to the
Company or the Guarantor. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and

                                      -12-

<PAGE>

(subject to Section 315 of the Trust Indenture Act) conclusive in favor of the
Trustee, the Company, the Guarantor and any agent of the Trustee, the Company or
the Guarantor, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities shall be proved in the manner provided in
Section 15.6.

         (2) Without limiting the generality of this Section 1.4, unless
otherwise provided in or pursuant to this Indenture or the related Series
Authorization, a Holder, including a U.S. Depository that is a Holder of a
global Security, may make, give or take, by a proxy or proxies duly appointed in
writing, any request, demand, authorization, direction, notice, consent, waiver
or other Act provided in or pursuant to this Indenture or the related Series
Authorization to be made, given or taken by Holders, and a U.S. Depository that
is a Holder of a global Security may provide its proxy or proxies to the
beneficial owners of interests in any such global Security through such U.S.
Depository's standing instructions and customary practices.

         (3) The Company shall fix a record date for the purpose of determining
the Persons who are beneficial owners of interest in any permanent global
Security held by a U.S. Depository entitled under the procedures of such U.S.
Depository to make, give or take, by a proxy or proxies duly appointed in
writing, any request, demand, authorization, direction, notice, consent, waiver
or other Act provided in or pursuant to this Indenture or the related Series
Authorization to be made, given or taken by Holders. If such a record date is
fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request,
demand, authorization, direction, notice, consent, waiver or other Act, whether
or not such Holders remain Holders after such record date. No such request,
demand, authorization, direction, notice, consent, waiver or other Act shall be
valid or effective if made, given or taken more than 90 days after such record
date.

         (4) The fact and date of the execution by any Person of any such
instrument or writing referred to in this Section 1.4 may be proved in any
reasonable manner; and the Trustee may in any instance require further proof,
including written proof, with respect to any of the matters referred to in this
Section.

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

         (6) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company,
wherever situated, if such certificate shall be deemed by the Company and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Trustee to be satisfactory. The Trustee and the
Company may assume that such ownership of any Bearer Security continues until
(i) another certificate or affidavit bearing a later date issued in respect of
the same Bearer Security is produced, or (ii) such Bearer Security is produced
to the Trustee by some other Person, or (iii) such Bearer

                                      -13-

<PAGE>

Security is surrendered in exchange for a Registered Security, or (iv) such
Bearer Security is no longer Outstanding. The ownership, principal amount and
serial numbers of Bearer Securities held by the Person so executing such
instrument or writing and the date of the commencement and the date of the
termination of holding the same may also be proved in any other manner which the
Company and the Trustee deem sufficient.

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

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

         Section 1.5.  Notices, etc.
                       ------------

         Any request, demand, authorization, direction, notice, consent, waiver
or other 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 the Company shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing to or with
the Trustee at its Corporate Trust Office, or

         (2) the Company by the Trustee or any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to the
attention of its Treasurer, with a copy to the attention of its General Counsel,
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.

         Section 1.6.  Notice to Holders of Securities; Waiver.
                       ---------------------------------------

         Except as otherwise expressly provided in or pursuant to this Indenture
or the related Series Authorization, where this Indenture provides for notice to
Holders of Securities of any event,

         (1) such notice shall be sufficiently given to Holders of Registered
Securities if in writing and mailed, first-class postage prepaid, to each Holder
of a Registered Security affected by such event, at his address as it appears in
the Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice; and

         (2) such notice shall be sufficiently given to Holders of Bearer
Securities, if any, if published in an Authorized Newspaper in The City of New
York and, if such Securities are then listed on any stock exchange outside the
United States, in an Authorized Newspaper in such city as the Company shall
advise the Trustee in writing that such stock exchange so requires, on a
Business Day at least twice, the first such publication to be not earlier than
the earliest date and the second such publication not later than the latest date
prescribed for the giving of such notice.

         In any case where notice to Holders of Registered Securities is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

         In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders of Securities shall be filed in writing
with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver.

         Section 1.7.  Language of Notices.
                       -------------------

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

                                      -15-

Company so elects, any published notice may be in an official language of the
country of publication.

                       ---------------------------------

         If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

         Section 1.9.  Effect of Headings and Table of Contents.

         Section 1.11. Separability Clause.
                       -------------------

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

         Section 1.12. Benefits of Indenture.
                       ---------------------

         Nothing in this Indenture, any Security or any Coupon, express or
implied, shall give to any Person, other than the parties hereto, any Security

hereunder and the Holders of Securities or Coupons, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

         Section 1.13. Governing Law.

related Series Authorization, in any case where any Interest Payment Date,
Stated Maturity or Maturity of any Security, or the last date on which a Holder
has the right to convert or exchange Securities of a series that are convertible
or exchangeable, shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture, any Security or any
Coupon other than a provision in any Security or Coupon that specifically states
that such provision shall apply in lieu hereof) payment need not be made at such
Place of Payment on such date, and such Securities need not be converted or
exchanged on such date but such payment may be made, and

                                      -16-

<PAGE>

such Securities may be converted or exchanged, on the next succeeding day that
is a Business Day at such Place of Payment with the same force and effect as if
made on the Interest Payment Date or at the Stated Maturity or Maturity or on
such last day for conversion or exchange, and no interest shall accrue on the
amount payable on such date or at such time for the period from and after such
Interest Payment Date, Stated Maturity, Maturity or last day for conversion or
exchange, as the case may be, to such next succeeding Business Day.

         Section 1.15. Counterparts.

             -----------------
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
               -----------------
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the requisite amount of the Required Currency with the
Judgme nt Currency on the New York Banking Day preceding the day on which a
final unappealable judgment is given and (b) its obligations under this
Indenture to make payments in the Required Currency (i) shall not be discharged
or satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with clause (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the

         Section 1.17. No Security Interest Created.
                       ----------------------------

or may be located.

         Section 1.18. Limitation on Individual Liability.
                       ----------------------------------

Company, either directly or through the Company, whether by virtue of any
constitution,

                                      -17-

otherwise; it being expressly understood that this Indenture and the obligations
issued hereunder are solely corporate obligations, and that no such personal
liability whatever shall attach to, or is or shall be incurred by, the
incorporators, shareholders, officers or directors, as such, of the Company, or
any of them, because of the creation of the indebtedness hereby authorized, or
under or by reason of the obligations, covenants or agreements contained in this

released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of such Security.

                       --------------------------

         The Company agrees that any judicial proceedings instituted in relation
to any matter arising under this Indenture, the Securities or any Coupons
appertaining thereto may be brought in any United States Federal or New York
State court sitting in the Borough of Manhattan, The City of New York, New York
to the extent that such court has subject matter jurisdiction over the
controversy, and, by execution and delivery of this Indenture, the Company
hereby irrevocably accepts, generally and unconditionally, the jurisdiction of
the aforesaid courts, acknowledges their competence and irrevocably agrees to be
bound by any judgment rendered in such proceeding. The Company also irrevocably
and unconditionally waives for the benefit of the Trustee and the Holders of the

attachment in the aid of execution, execution or otherwise) in respect of this
Indenture. The Company hereby irrevocably designates and appoints for the
benefit of the Trustee and the Holders of the Securities and Coupons for the
term of this Indenture PartnerRe U.S. Corporation, One Greenwich Plaza,

binding service on it in every respect whether or not the Company shall then be
doing or shall have at any time done business in New York. Such appointment
shall be irrevocable so long as any of the Securities or Coupons or the
obligations of the Company hereunder remain outstanding, or until the
appointment of a successor by the Company located in New York or Connecticut and
such successor's acceptance of such appointment. Upon such acceptance, the
Company shall notify the Trustee in writing of the name and address of such

Corporation as its agent in full force and effect so long as any of the
Securities or Coupons or the obligations of the Company hereunder shall be
outstanding. The Trustee shall not be obligated and shall have no responsibility
with respect to any failure by the Company to take any such action. Nothing

         Unless otherwise provided in or pursuant to the related Series
Authorization, the Securities of a series shall not be issuable in temporary or
permanent global form. If Securities of a series shall be issuable in global
form, any such Security may provide that it or any number of such Securities
shall represent the aggregate amount of all Outstanding Securities of such
series (or such lesser amount as is permitted by the terms thereof) from time to
time endorsed thereon and may also provide that the aggregate amount of
Outstanding Securities represented thereby may from time to time be increased or
reduced to reflect exchanges. Any endorsement of any Security in global form to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders, of Outstanding Securities represented thereby shall be made
in such manner and by such Person or Persons as shall be specified therein or in
the Company Order to be delivered pursuant to Section 3.3 or Section 3.4 with
respect thereto. Subject to the provisions of Section 3.3 and, if applicable,
Section 3.4, the Trustee shall deliver and redeliver, in each case at the
Company's expense, any Security in permanent global form in the manner and upon
written instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 3.3 or Section
3.4 has been, or simultaneously is, delivered, any instructions by the Company
with respect to a Security in global form shall be in writing and, with respect
to matters set forth in this Section 2.3, need not be accompanied by or
contained in an Officers' Certificate and need not be accompanied by an Opinion
of Counsel.

         Notwithstanding the provisions of Section 3.7, unless otherwise
specified in or pursuant to the related Series Authorization, payment of
principal of, any premium and interest on, and any Additional Amounts in respect
of, any Security in temporary or permanent global form shall be made to the
Person or Persons specified therein.

         Notwithstanding the provisions of Section 3.8 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
or the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a global Security (i) in the case of a global Security
in registered form, the Holder of such global Security in registered form, or
(ii) in the case of a global Security in bearer form, the Person or Persons
specified pursuant to Section 3.1.

conditions (including any certification requirements) upon which any such
interest payment received by a clearing organization will be credited to the

payable, any of such Securities that are Registered Securities may be

<PAGE>

Indenture (regardless of whether this Indenture otherwise provides that such
other terms or provisions are subject to the provisions of the related Series
Authorization), the terms and provisions of the related Series Authorization
shall control.

         All Securities of any one series and all Coupons, if any, appertaining
to Bearer Securities of such series shall be substantially identical except as
to Currency of payments due thereunder, denomination and the rate of interest
thereon, or method of determining the rate of interest, if any, Maturity, and
the date from which interest, if any, shall accrue and except as may otherwise
be provided by the Company in or pursuant to the Board Resolution and set forth
in the Officers' Certificate or in any indenture or indentures supplemental
hereto pertaining to such series of Securities. The terms of the Securities of
any series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time
upon written order of persons designated in the Officers' Certificate or
supplemental indenture and that such persons are authorized to determine,
consistent with such Officers' Certificate or any applicable supplemental
indenture, such terms and conditions of the Securities of such series as are
specified in such Officers' Certificate or supplemental indenture. All
Securities of any one series need not be issued at the same time and, unless
otherwise so provided, a series may be reopened for issuances of additional
Securities of such series or to establish additional terms of such series of
Securities.

         If any of the terms of the Securities of any series shall be
established by action taken by or pursuant to a Board Resolution, the Board
Resolution shall be delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth the terms of such series.

         Section 3.2. Currency; Denominations.
                      -----------------------

         Unless otherwise provided in or pursuant to this Indenture or the
related Series Authorization, the principal of, any premium and interest on and
any Additional Amounts with respect to the Securities shall be payable in
Dollars. Unless otherwise provided in or pursuant to this Indenture or the
related Series Authorization, Registered Securities denominated in Dollars shall
be issuable in registered form without Coupons in denominations of $1,000 and
any integral multiple thereof, and the Bearer Securities denominated in Dollars
shall be issuable in the denomination of $5,000. Securities not denominated in
Dollars shall be issuable in such denominations as are established with respect
to such Securities in or pursuant to this Indenture or the related Series
Authorization.

         Section 3.3. Execution, Authentication, Delivery and Dating.
                      ----------------------------------------------

         Securities shall be executed on behalf of the Company by an Authorized
Officer and attested by a different Authorized Officer. Coupons shall be
executed on behalf of the Company by the Chief Financial Officer or Chief
Accounting Officer of the Company. The signature of any of these officers on the
Securities or any Coupons appertaining thereto may be manual or facsimile.

         Securities and any Coupons appertaining thereto 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

                                      -24-

<PAGE>

prior to the authentication and delivery of such Securities and Coupons or did
not hold such offices at the date of original issuance of such Securities or
Coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officers' Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 3.1 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in, and may conclusively rely
upon,

         (1) an Opinion or Opinions of Counsel that comply with Section 314 of
the Trust Indenture Act; and

         (2) an Officers' Certificate stating that all conditions precedent to
the execution, authentication and delivery of such Securities and Coupons, if
any, appertaining thereto, have been complied with and that, to the best
knowledge of the Persons executing such certificate, no event which is, or after
notice or lapse of time would become, an Event of Default with respect to any of
the Securities shall have occurred and be continuing.

         If all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Opinion of Counsel and an Officers'
Certificate at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate written request by an Authorized Officer of the Company
or any person designated in writing by an Authorized Officer that the Trustee
authenticate and deliver Securities of such series for original issue will be
deemed to be a certification by the Company that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with.

         The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities, nor will it be liable for
its refusal to authenticate or cause an Authenticating Agent to authenticate any
Securities, if the issue of such Securities will affect the Trustee's own
rights, duties or immunities under the Securities and this Indenture or
otherwise in a manner which is not reasonably acceptable to the Trustee or if
the Trustee, being advised by counsel, determines that such action may not
lawfully be taken or may expose the Trustee to personal liability to existing
Holders or others.

         Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to the related Series Authorization.

                                      -25-

<PAGE>

         No Security or Coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose, unless
there appears on such Security a certificate of authentication substantially in
the form provided for in Section 2.2 or Section 6.11 executed by or on behalf of
the Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 3.6 or Section 3.7, the
Trustee shall not authenticate and deliver any Bearer Security unless all
Coupons appertaining thereto then matured have been detached and cancelled.

         Section 3.4. Temporary Securities.
                      --------------------

         Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture or the related Series Authorization, in bearer form with one or more
Coupons or without Coupons and with such appropriate insertions, omissions,
substitutions and other variations as the officers of the Company executing such
Securities may determine, as conclusively evidenced by their execution of such
Securities. Such temporary Securities may be in global form.

         Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee upon Company Order shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of authorized
denominations of the same series and containing identical terms and provisions;
provided, however, that no definitive Bearer Security, except as provided in or
pursuant to this Indenture or the related Series Authorization, shall be
delivered in exchange for a temporary Registered Security; and provided,
further, that a definitive Bearer Security shall be delivered in exchange for a
temporary Bearer Security only in compliance with the conditions set forth in or
pursuant to this Indenture or the related Series Authorization. Unless otherwise
provided in or pursuant to this Indenture or the related Series Authorization
with respect to a temporary global Security, 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 3.5. Registration, Transfer and Exchange.
                      -----------------------------------

         With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security
                              --------

                                      -26-

<PAGE>

Register") at an Office or Agency for such series in which, subject to such
--------
reasonable regulations as it may prescribe, the Company shall provide for the
registration of the Registered Securities of such series and of transfers of the
Registered Securities of such series. Such Office or Agency shall be the
"Security Registrar" for that series of Securities. Unless otherwise specified
 ------------------
in or pursuant to this Indenture or the related Series Authorization, the
Trustee shall be the initial Security Registrar for each series of Securities.
The Company shall have the right to remove and replace from time to time the
Security Registrar for any series of Securities; provided that no such removal
or replacement shall be effective until a successor Security Registrar with
respect to such series of Securities shall have been appointed by the Company
and shall have accepted such appointment by the Company. In the event that the
Trustee shall not be or shall cease to be Security Registrar with respect to a
series of Securities, it shall have the right to examine the Security Register
for such series at all reasonable times. There shall be only one Security
Register for each series of Securities.

         Upon surrender for registration of transfer of any Registered Security
of any series at any Office or Agency for such 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 Registered Securities of
the same series denominated as authorized in or pursuant to this Indenture or
the related Series Authorization, of a like aggregate principal amount bearing a
number not contemporaneously outstanding and containing identical terms and
provisions.

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

         If provided in or pursuant to this Indenture or the related Series
Authorization, with respect to Securities of any series, at the option of the
Holder, Bearer Securities of such series may be exchanged for Registered
Securities of such series containing identical terms, denominated as authorized
in or pursuant to this Indenture or the related Series Authorization and in the
same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining. If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 10.2, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States.

                                      -27-

Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the next succeeding Interest Payment Date,
or (ii) any Special Record Date and before the opening of business at such
Office or Agency on the related date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the Coupon relating to such
Interest Payment Date or proposed date of payment, as the case may be (or, if
such Coupon is so surrendered with such Bearer Security, such Coupon shall be
returned to the Person so surrendering the Bearer Security), and interest or
Defaulted Interest, as the case may be, shall not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

         If provided in or pursuant to this Indenture or the related Series
Authorization, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture or the related Series Authorization.

         Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture or the related Series Authorization, any global
Security shall be exchangeable for definitive Securities only if (i) the
Depository is at any time unwilling, unable or ineligible to continue as
depository and a successor depository is not appointed by the Company within 90
days of the date the Company is so informed in writing, (ii) the Company
executes and delivers to the Trustee a Company Order to the effect that such
global Security shall be so exchangeable, or (iii) an Event of Default has
occurred and is continuing with respect to the Securities. If the beneficial
owners of interests in a global Security are entitled to exchange such interests
for definitive Securities as the result of an event described in clause (i),
(ii) or (iii) of the preceding sentence, then without unnecessary delay but in
any event not later than the earliest date on which such interests may be so
exchanged, the Company shall deliver to the Trustee definitive Securities in
such form and denominations as are required by or pursuant to this Indenture or
the related Series Authorization, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such global Security shall be surrendered
from time to time by the U.S. Depository or such other Depository as shall be
specified in the Company Order with respect thereto, and in accordance with
instructions given to the Trustee and the U.S. Depository or such other
Depository, as the case may be (which instructions shall be in writing but need
not be contained in or accompanied by an Officers' Certificate or be accompanied
by an Opinion of Counsel), as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above
without charge. The Trustee shall authenticate and make available for delivery,
in exchange for

                                      -28-

<PAGE>

each portion of such surrendered global Security, a like aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such global Security to be exchanged, which
(unless such Securities are not issuable both as Bearer Securities and as
Registered Securities, in which case the definitive Securities exchanged for the
global Security shall be issuable only in the form in which the Securities are
issuable, as provided in or pursuant to this Indenture or the related Series
Authorization) shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified by the beneficial
owner thereof, but subject to the satisfaction of any certification or other
requirements to the issuance of Bearer Securities; provided, however, that no
such exchanges may occur during a period beginning at the opening of business 15
days before selection of Securities of the same series to be redeemed and ending
on the relevant Redemption Date; and provided, further, that (unless otherwise
provided in or pursuant to this Indenture or the related Series Authorization)
no Bearer Security delivered in exchange for a portion of a global Security
shall be mailed or otherwise delivered to any location in the United States.
Promptly following any such exchange in part, such global Security shall be
returned by the Trustee to such Depository or the U.S. Depository, as the case
may be, or such other Depository or U.S. Depository referred to above in
accordance with the instructions of the Company referred to above. If a
Registered Security is issued in exchange for any portion of a global Security
after the close of business at the Office or Agency for such Security where such
exchange occurs on or after (i) any Regular Record Date for such Security and
before the opening of business at such Office or Agency on the next succeeding
Interest Payment Date, or (ii) any Special Record Date for such Security and
before the opening of business at such Office or Agency on the related proposed
date for payment of interest or Defaulted Interest, as the case may be, interest
shall not be payable on such Interest Payment Date or proposed date for payment,
as the case may be, in respect of such Registered Security, but shall be payable
on such Interest Payment Date or proposed date for payment, as the case may be,
only to the Person to whom interest in respect of such portion of such global
Security shall be payable in accordance with the provisions of this Indenture.

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

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, Section 9.5 or Section 11.7 not
involving any transfer.

         Except as otherwise provided in or pursuant to this Indenture or the
related Series Authorization, the Company shall not be required (i) to issue,
register the transfer of or exchange any Securities during a period beginning at
the opening of business 15 days before the day of mailing of a notice of
redemption of Securities of like tenor and the same series under Section 11.4
and ending at the close of business on the day of such mailing, or (ii) to
register the transfer of or exchange any Registered Security selected for
redemption in whole or in part, except in the case of any Security to be
redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange
any Bearer Security selected for redemption except, to the extent provided with
respect to such Bearer Security, that such Bearer Security may be exchanged for
a Registered Security of like tenor and the same series, provided that such
Registered Security shall be immediately surrendered for redemption with written
instruction for payment consistent with the provisions of this Indenture or (iv)
to issue, register the transfer of or exchange any Security which, in accordance
with its terms, has been surrendered for repayment at the option of the Holder,
except the portion, if any, of such Security not to be so repaid.

         Section 3.6. Mutilated, Destroyed, Lost and Stolen Securities.
                      ------------------------------------------------

         If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

         If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or Coupon has been acquired by a
protected purchaser, the Company shall execute and, upon the Company's request
the Trustee shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons appertaining thereto
corresponding to the Coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.

         Notwithstanding the foregoing provisions of this Section 3.6, in case
any mutilated, destroyed, lost or stolen Security or Coupon 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 or Coupon; provided, however, that
payment of principal of, any premium or interest on or any Additional Amounts
with respect to any Bearer Securities shall, except as otherwise provided in
Section 10.2, be payable only at an Office or Agency for such Securities located
outside the United States and, unless otherwise provided in or pursuant to this
Indenture or the related Series Authorization, any interest on Bearer Securities
and any Additional Amounts with respect to such interest shall be payable only
upon presentation and surrender of the Coupons appertaining thereto.

                                      -30-

<PAGE>

     Upon the issuance of any new Security under this Section 3.6, 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 and the fees and
expenses of the Trustee's counsel) connected therewith.

     Every new Security, with any Coupons appertaining thereto issued pursuant
to this Section 3.6 in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company, whether or not the
destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon 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 such series and any
Coupons, if any, duly issued hereunder.

     The provisions of this Section 3.6, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
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 or Coupons.

     Section 3.7.   Payment of Interest and Certain Additional Amounts; Rights
                    ----------------------------------------------------------
to Interest and Certain Additional Amounts Preserved.
----------------------------------------------------

     Unless otherwise provided in or pursuant to this Indenture or the related
Series Authorization, any interest on and any Additional Amounts with respect to
any Registered Security which shall be payable, and are punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name such Security (or one or more Predecessor Securities) is registered as of
the close of business on the Regular Record Date for such interest.

     Unless otherwise provided in or pursuant to this Indenture or the related
Series Authorization, any interest on and any Additional Amounts with respect to
any Registered Security which shall be payable, but shall not be punctually paid
or duly provided for, on any Interest Payment Date for such Registered Security
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
                ------------------
Holder thereof 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
Person in whose name such Registered Security (or a Predecessor Security
thereof) shall be registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest, which shall be fixed by the Company
in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on such Registered Security,
the Special Record Date therefor 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
on or prior to the date of the proposed payment, such money when so deposited to
be held in trust in a segregated trust account pursuant to express written
instructions of the Company for the benefit of the Person entitled to such
Defaulted Interest as in

                                      -31-

<PAGE>

this Clause provided. The Special Record Date for the payment of such Defaulted
Interest 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 notification to the
Trustee of the proposed payment. The Trustee shall, in the name and at the
expense of the Company, cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be mailed, first-class postage
prepaid, to the Holder of such Registered Security (or a Predecessor Security
thereof) at his address as it appears in the Security Register not less than 10
days prior to such Special Record Date. If such Defaulted Interest relates to
Securities of a series that are issued as Bearer Securities, the Trustee shall,
in the name and at the expense of the Company cause a similar notice to be
published at least once in an Authorized Newspaper of general circulation in the
Borough of Manhattan, The City of New York, but such publication shall not be a
condition precedent to the establishment of such Special Record Date. Notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been mailed as aforesaid, such Defaulted Interest shall be paid
to the Person in whose name such Registered Security (or a Predecessor Security
thereof) shall be 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 in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which such Security may be listed, and upon such notice as may be required by
such exchange, if, after written notice given by the Company to the Trustee of
the proposed payment pursuant to this Clause, such payment shall be deemed
practicable by the Trustee.

     Unless otherwise provided in or pursuant to this Indenture or the related
Series Authorization of any particular series pursuant to the provisions of this
Indenture, at the option of the Company, interest on Registered Securities that
bear interest may be paid by mailing a check to the address of the Person
entitled thereto as such address shall appear in the Security Register or by
wire transfer to an account maintained by the payee with a bank located in the
United States.

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

     In the case of any Registered Security of any series that is convertible
into shares of Common Stock of the Company or exchangeable for other securities,
which Registered Security is converted or exchanged after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Registered Security with respect to which the Stated Maturity is prior to
such Interest Payment Date), interest with respect to which the Stated Maturity
is on such Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion or exchange, and such interest (whether or not
punctually paid or duly provided for) shall be paid to the Person in whose name
that Registered Security (or one or more predecessor Registered Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Registered Security which is converted or exchanged, interest with
respect to

                                      -32-

<PAGE>

which the Stated Maturity is after the date of conversion or exchange of such
Registered Security shall not be payable.

     Section 3.8.   Persons Deemed Owners.
                    ---------------------

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 3.5 and
3.7) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall 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.

     The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall 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.

     No Holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

     Section 3.9.   Cancellation.
                    ------------

     All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. 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 cancelled promptly by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted
by or pursuant to this Indenture or the related Series Authorization. All
cancelled Securities and Coupons held by the Trustee shall be destroyed by the
Trustee, unless by a Company Order the Company directs their return to it.

                    -----------------------

     Except as otherwise provided in or pursuant to this Indenture or the
related Series Authorization, interest on the Securities shall be computed on
the basis of a 360-day year of twelve 30-day months.

     Section 3.11.  CUSIP Numbers.
                    -------------

     The Company in issuing the Securities may use "CUSIP," "CINS" and "ISIN"
numbers (if then generally in use), and the Trustee shall use CUSIP, CINS or
ISIN numbers, as the case may be, in notices of redemption or exchange as a
convenience to Holders and no representation shall be made as to the correctness
of such numbers either as printed on the Securities or as contained in any
notice of redemption or exchange. The Company shall promptly notify the Trustee
of any change in CUSIP, CINS or ISIN numbers.

cease to be of further effect with respect to any series of Securities specified
in such Company Order and any Coupons appertaining thereto, and the Trustee, on
receipt of a Company Order, at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series, when

     for Registered Securities of such series and maturing after such exchange
     whose surrender is not required or has been waived as provided in Section

          within one year under arrangements satisfactory to the Trustee for the
          giving of notice of redemption by the Trustee in the name, and at the
          expense, of the Company,

Securities of such series as to which it is Trustee and if the other conditions

     one day before the due date of any payment with respect to such Securities
     and any Coupons appertaining thereto, money in an amount, or (3) a
     combination thereof, in any case, in an amount, sufficient, without
     consideration of any reinvestment of such principal and interest, in the
     opinion of a nationally recognized firm of independent public accountants

     that (i) the Company or the Guarantor has received from the Internal
     Revenue Service a letter ruling, or there has been published by the
     Internal Revenue Service a Revenue Ruling, or (ii) since the date of
     execution of this Indenture, there has been a change in the applicable
     Federal income tax law, in either case to the effect that, and based
     thereon such opinion shall confirm that, the Holders of such Outstanding
     Securities and any Coupons appertaining thereto will not recognize income,
     gain or loss for Federal income tax purposes as a result of such defeasance
     and will be subject to Federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such defeasance
     had not occurred.

          (e) In the case of an election under clause (3) of this Section 4.2

     had not occurred.

          (f) With respect to defeasance only, the Company or the Guarantor
     shall have delivered to the Trustee an Opinion of Counsel to the effect

     shall have delivered to the Trustee an Officers' Certificate and a
     Guarantor's Officer's Certificate as to solvency and the absence of any
     intent of preferring the Holders over any other creditors of the Company.

          (h) The Company and the Guarantor shall have delivered to the Trustee
     an Officers' Certificate and a Guarantor's Officer's Certificate and an
     Opinion of Counsel, each stating that all conditions precedent to the

     4.2 (as the case may be) have been complied with.

made is entitled to, and does, elect pursuant to Section 3.1 or the terms of
such Security to receive payment in a Currency other than that in which the
deposit pursuant to Section 4.2(4)(a) has been made in respect of such Security,
or (b) a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 4.2(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other property deposited
in respect of such Security into the Currency in which such Security becomes
payable as a result of such election or Conversion Event based on (x) in the
case of payments made pursuant to clause (a) above, the applicable market
exchange rate for such Currency in effect on the second Local Business Day prior
to each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event. "Local Business Day" means a day on which
                                      ------------------
commercial banks are open for business (including dealings in foreign exchange)
in the principal financial center of the Currency of such payment.

     The Company and the Guarantor (without duplication) shall pay and indemnify
the Trustee (or other qualifying trustee, collectively for purposes of this
Section 4.2(5) and Section 4.3, the "Trustee") against any tax, fee or other
                                     -------
charge, imposed on or assessed against the Government Obligations deposited
pursuant to this Section 4.2 or the principal or interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

     Anything in this Section 4.2 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request, or
the Guarantor upon Guarantor

Request, as the case may be, any money or Government Obligations (or other
property and any proceeds therefrom) held by it as provided in clause (4) of
this Section 4.2 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect a defeasance or covenant defeasance, as
applicable, in accordance with this Section 4.2.

     Section 4.3. Application of Trust Money.
                  --------------------------

     Subject to the provisions of the last paragraph of Section 10.3, all money
and Government Obligations (or other property as may be provided pursuant to
Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or Section 4.2 in respect of any Outstanding Securities
of any series and any Coupons appertaining thereto shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Securities and
any Coupons appertaining thereto and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities
and any Coupons appertaining thereto of all sums due and to become due thereon
in respect of principal (and premium, if any) and interest and Additional
Amounts, if any; but such money and Government Obligations need not be
segregated from other funds except to the extent required by law.

     Section 4.4. Reinstatement.
                  -------------

     If the Trustee or Paying Agent is unable to apply any money or Government
Obligations in accordance with Sections 4.3 by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture and the Securities of the applicable series
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 4.1 or 4.2, as the case may be, until such time as the Trustee or Paying
Agent is permitted to apply all such money or Government Obligations in
accordance with Section 4.3; provided, that, if the Company has made any payment
of principal of or interest on the Securities of any series because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or
Government Obligations held by the Trustee or Paying Agent.

Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series, by written notice to the Company or

payable and such default continues for a period of 30 days, or

     (2) default is made in the payment of the principal of or any premium on
any Security or any Additional Amounts with respect thereto at their Maturity,
the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money

                                      -43-

then due and payable with respect to such Securities and any Coupons
appertaining thereto, with interest upon the overdue principal, any premium and,
to the extent that payment of such interest shall be legally enforceable, upon

further amount of money as shall be sufficient to cover the costs and expenses
of collection, including the reasonable compensation, expenses, disbursements

the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company and/or the Guarantor or any other obligor upon such
Securities and any Coupons appertaining thereto and collect the monies adjudged
or decreed to be payable in the manner provided by law out of the property of
the Company and/or the Guarantor or any other obligor upon such Securities and
any Coupons appertaining thereto, wherever situated.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

affecting the Securities or Coupons or the rights of any Holder thereof, or to

     No Holder of any Security of any series or any Coupons appertaining thereto
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 such series;

     (2) the Holders of not less than 25% in principal amount of the Outstanding
Securities of such 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 such indemnity as is
reasonably 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 such 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 or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, or to
obtain or to seek to obtain priority or preference over any other Holders or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

receive payment of the principal of, any premium and (subject to Sections 3.5
and 3.7) interest on, and any Additional Amounts with respect to such Security
or payment of such Coupon, as the case may be, on the respective Stated Maturity
or Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder if provided with respect to such Security, on the date such
repayment is due) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

     Section 5.9. Restoration of Rights and Remedies.
                  ----------------------------------

     If the Trustee or any Holder of a Security or a Coupon has instituted any

                                      -46-

<PAGE>

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

exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in

hereunder, or otherwise, shall not, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

     Section 5.11. Delay or Omission Not Waiver.
                   ----------------------------

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

of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee with respect to the Securities of
such series and any Coupons appertaining thereto, provided that

     (1) such direction shall not be in conflict with any rule of law or with
this Indenture or with the Securities of such series,

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

     (3) such direction is not unduly prejudicial to the rights of the other
Holders of Securities of such series not joining in such action.

                   -----------------------

     Subject to Section 5.2, the Holders of not less than a majority in

Holders of all the Securities of such series

                                      -47-

<PAGE>

and any Coupons appertaining thereto may waive any past default hereunder with
respect to such series and its consequences, except a default

     (1) in the payment of the principal of, any premium or interest on, or any
Additional Amounts with respect to, any Security of such series or any Coupons
appertaining thereto, or

     (2) in respect of a covenant or provision hereof which under Article 9
cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected.

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

     Section 5.14. Waiver of Usury, Stay or Extension Laws.
                   ---------------------------------------

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

     Section 5.15. Undertaking for Costs.
                   ---------------------

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 5.15 shall not apply 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 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, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment or repurchase, on or
after the date for repayment or repurchase) or for the enforcement of the right,
if any, to convert or exchange any Security into Common Stock or other
securities in accordance with its terms.

acceptance of appointment by the successor Trustee pursuant to Section 6.9.

     (2) 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 6.9 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to such
series.

     (3) The Trustee may be removed at any time with respect to the Securities

     it under Section 310(b) of the Trust Indenture Act with respect to

     and all others similarly situated, petition any court of competent
     jurisdiction

to the Securities of one or more series, the Company, by or pursuant to a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect

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

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 6.9, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders of Securities and accepted appointment in the manner required by
Section 6.9, any Holder of a Security who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for

     (1) Upon the appointment hereunder of any successor Trustee with respect to
all Securities, such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company and 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

Company or such successor Trustee, such retiring Trustee, upon payment of its
charges, shall execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and, subject
to Section 10.3, shall duly assign, transfer and deliver to such

                                      -54-

hereunder, subject nevertheless to its claim, if any, provided for in Section
6.6.

Trustee and such successor Trustee 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, such 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

Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust, that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee and that no Trustee shall be responsible
for any notice given to, or received by, or any act or failure to act on the
part of any other Trustee hereunder, and, upon the execution and delivery of
such supplemental indenture, the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein, such retiring Trustee
shall have no further responsibility for the exercise of rights and powers or
for the performance of the duties and obligations vested in the Trustee under
this Indenture with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates other than as hereinafter
expressly set forth, and such successor Trustee, without any further act, deed

     Section 6.10.  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 of the corporate agency or
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, 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 6.11.  Appointment of Authenticating Agent.
                    -----------------------------------

     The Trustee may appoint one or more Authenticating Agents acceptable to the
Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment or pursuant to Section 3.6, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

     Each Authenticating Agent must be acceptable to the Company and, except as
provided in or pursuant to this Indenture or the related Series Authorization,
shall at all times be a Corporation that would be permitted by the Trust
Indenture Act to act as trustee under an indenture qualified under the Trust
Indenture Act, is authorized under applicable law and by its charter to act as
an Authenticating Agent and has a combined capital and surplus (computed in
accordance with Section 310(a)(2) of the Trust Indenture Act) of at least
$50,000,000. If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect specified in this Section.

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

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions

                                      -56-

of this Section, the Trustee may appoint a successor Authenticating Agent which
shall be acceptable to the Company and shall (i) mail written notice of such
appointment by first-class mail, postage prepaid, to all Holders of Registered
Securities, if any, of the series with respect to which such Authenticating
Agent shall serve, as their names and addresses appear in the Security Register,
and (ii) if Securities of the series are issued as Bearer Securities, publish
notice of such appointment at least once in an Authorized Newspaper in the place
where such successor Authenticating Agent has its principal office if such
office is located outside the United States. Any successor Authenticating Agent,
upon acceptance of its appointment hereunder, shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

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

     The provisions of Section 3.8, Section 6.3 and Section 6.4 shall be
applicable to each Authenticating Agent.

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

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

                              By:__________________________________
                                 as Authenticating Agent


                              By:__________________________________
                                 as Authorized Officer

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

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

                                      -64-

may be prepared and executed by the Company and authenticated and delivered by
the Trustee in exchange for Outstanding Securities of such series.

     Section 9.7.  Notice of Supplemental Indenture.
                   --------------------------------

     Promptly after the execution by the Company and the Guarantor, if
applicable, and the Trustee of any supplemental indenture pursuant to Section
9.2, the Company shall transmit to the Holders of Outstanding Securities of any
series affected thereby a notice setting forth the substance of such
supplemental indenture.

     Section 10.1. Payment of Principal, any Premium, Interest and Additional
                   ----------------------------------------------------------
Amounts.
-------

     The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

     Section 10.2. Maintenance of Office or Agency.
                   -------------------------------

     The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company, except as otherwise permitted or
required in or pursuant to this Indenture or the related Series Authorization
shall maintain, subject to any laws or regulations applicable thereto, an Office
or Agency in a Place of Payment for such series which is located outside the
United States where Securities of such series and any Coupons appertaining
thereto may be presented and surrendered for payment; provided, however, that if
the Securities of such series are listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any
other stock exchange located outside the United States and such stock exchange
shall so require, the Company shall maintain a Paying Agent in London,
Luxembourg or any other required city located outside the United States, as the
case may be, so long as the

                                      -65-

<PAGE>

Securities of such series are listed on such exchange. 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, except that
Bearer Securities of such series and any Coupons appertaining thereto may be
presented and surrendered for payment at the place specified for the purpose
with respect to such Securities as provided in or pursuant to this Indenture or
the related Series Authorization, and the Company hereby appoints the Trustee as
its agent to receive all such presentations, surrenders, notices and demands.

         Except as otherwise provided in or pursuant to this Indenture or the
related Series Authorization, no payment of principal, premium, interest or
Additional Amounts with respect to Bearer Securities shall be made at any Office
or Agency in the United States or by check mailed to any address in the United
States or by wire transfer to an account maintained with a bank located in the
United States; provided, however, if amounts owing with respect to any Bearer
Securities shall be payable in Dollars, payment of principal of, any premium or
interest on and any Additional Amounts with respect to any such Security may be
made at the Corporate Trust Office of the Trustee or any Office or Agency
designated by the Company in the Borough of Manhattan, The City of New York, if
(but only if) payment of the full amount of such principal, premium, interest or
Additional Amounts at all offices outside the United States maintained for such
purpose by the Company in accordance with this Indenture is illegal or
effectively precluded by exchange controls or other similar restrictions.

         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 shall give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other Office or Agency. Unless otherwise provided in or pursuant to this
Indenture or the related Series Authorization, the Company hereby designates as
the Place of Payment for each series of Securities the Borough of Manhattan, The
City of New York, and initially appoints the Corporate Trust Office of the
Trustee as the Office or Agency of the Company in the Borough of Manhattan, The
City of New York for such purpose. The Company may subsequently appoint a
different Office or Agency in the Borough of Manhattan, The City of New York for
the Securities of any series.

         Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

         Section 10.3. Money for Securities Payments to Be Held in Trust.
                       -------------------------------------------------

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or

                                      -66-

<PAGE>

Additional Amounts with respect to any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum in the currency or currencies, currency unit or units or composite currency
or currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 3.1 for the Securities of such series)
sufficient to pay the principal or any premium, interest or Additional Amounts
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and shall promptly notify the Trustee in writing
of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it shall, on or prior to 10:00 a.m., New York City time,
on each due date of the principal of, any premium or interest on or any
Additional Amounts with respect to any Securities of such series, deposit with
any Paying Agent a sum (in the currency or currencies, currency unit or units or
composite currency or currencies described in the preceding paragraph)
sufficient to pay the principal and any premium, interest or Additional Amounts
so becoming due, such sum to be held in trust for the benefit of the Persons
entitled thereto, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee in writing of its action or failure so to act.

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

         (1) hold all sums held by it for the payment of the principal of, any
premium or interest on or any Additional Amounts with respect to Securities of
such 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 provided in or
pursuant to this Indenture or the related Series Authorization;

         (2) give the Trustee notice of any default by the Company (or any other
obligor upon the Securities of such series) in the making of any payment of
principal of, any premium or interest on or any Additional Amounts with respect
to the Securities of such 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 terms as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

         Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have become
due and payable shall be paid to the Company on Company Request, or (if then
held by

                                      -67-

<PAGE>

the Company) shall be discharged from such trust; and the Holder of such
Security or any Coupon appertaining thereto 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, at the expense of the Company may cause to be
published once, in an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing nor shall it be later than two years after such principal or any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

         Section 10.4. Additional Amounts.
                       ------------------

         Except as otherwise provided in or pursuant to the related Series
Authorization of the applicable series, all payments of principal of and
premium, if any, interest and any other amounts on, or in respect of, the
Securities of any series or any Coupon appertaining thereto shall be made
without withholding or deduction at source for, or on account of, any present or
future taxes, fees, duties, assessments or governmental charges of whatever
nature imposed or levied by or on behalf of any jurisdiction in which the
Company is organized (each, a "taxing jurisdiction") or any political
                               -------------------
subdivision or taxing authority thereof or therein, unless such taxes, fees,
duties, assessments or governmental charges are required to be withheld or
deducted by (i) the laws (or any regulations or ruling promulgated thereunder)
of a taxing jurisdiction or any political subdivision or taxing authority
thereof or therein or (ii) an official position regarding the application,
administration, interpretation or enforcement of any such laws, regulations or
rulings (including, without limitation, a holding by a court of competent
jurisdiction or by a taxing authority in a taxing jurisdiction or any political
subdivision thereof). If a withholding or deduction at source is required, the
Company shall, subject to certain limitations and exceptions set forth below,
pay to the Holder of any such Security or any Coupon appertaining thereto such
Additional Amounts as may be necessary so that every net payment of principal,
premium, if any, interest or any other amount made to such Holder, after such
withholding or deduction, shall not be less than the amount provided for in such
Security, any Coupons appertaining thereto and this Indenture to be then due and
payable; provided, however, that the Company shall not be required to make
payment of such Additional Amounts for or on account of:

         (1) any tax, fee, duty, assessment or governmental charge of whatever
nature which would not have been imposed but for the fact that such Holder: (A)
was a resident, domiciliary or national of, or engaged in business or maintained
a permanent establishment or was physically present in, the relevant taxing
jurisdiction or any political subdivision thereof or otherwise had some
connection with the relevant taxing jurisdiction other than by reason of the
mere ownership of, or receipt of payment under, such Security; (B) presented
such Security for payment in the relevant taxing jurisdiction or any political
subdivision thereof, unless such Security could not have been presented for
payment elsewhere; or (C) presented such Security more than thirty (30) days
after the date on which the payment in respect of such Security first became due
and payable or provided for, whichever is later, except to the extent that the
Holder would have been

                                      -68-

<PAGE>

entitled to such Additional Amounts if it had presented such Security for
payment on any day within such period of thirty (30) days;

         (2) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

         (3) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of such
Security to comply with any reasonable request by the Company addressed to the
Holder within 90 days of such request (A) to provide information concerning the
nationality, residence or identity of the Holder or such beneficial owner or (B)
to make any declaration or other similar claim or satisfy any information or
reporting requirement, which, in the case of (A) or (B), is required or imposed
by statute, treaty, regulation or administrative practice of the relevant taxing
jurisdiction or any political subdivision thereof as a precondition to exemption
from all or part of such tax, assessment or other governmental charge; or

         (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required
by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of the
Security.

         Whenever in this Indenture there is mentioned, in any context, the
payment of the principal of or any premium, interest or any other amounts on, or
in respect of, any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
by the terms of such series established hereby or pursuant hereto to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to such terms, and express mention of the payment of
Additional Amounts (if applicable) in any provision hereof shall not be
construed as excluding the payment of Additional Amounts in those provisions
hereof where such express mention is not made.

         Except as otherwise provided in or pursuant to this Indenture or the
related Series Authorization of the applicable series, at least 10 days prior to
the first Interest Payment Date with respect to such series of Securities (or if
the Securities of such series shall not bear interest prior to Maturity, the
first day on which a payment of principal is made), and at least 10 days prior
to each date of payment of principal or interest if there has been any change
with respect to the matters set forth in the below-mentioned Officers'
Certificate, the Company shall furnish to the Trustee and the principal Paying
Agent or Paying Agents, if other than the Trustee, an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and premium, if any, interest or any other amounts on
the Securities of such series shall be made to Holders of Securities of such
series or the Coupons appertaining

                                      -69-

<PAGE>

thereto without withholding for or on account of any tax, fee, duty, assessment
or other governmental charge described in this Section 10.4. If any such
withholding shall be required, then such Officers' Certificate shall specify by
taxing jurisdiction the amount, if any, required to be withheld on such payments
to such Holders of Securities or Coupons, and the Company agrees to pay to the
Trustee or such Paying Agent the Additional Amounts required by this Section
10.4. The Company covenants to indemnify the Trustee and any Paying Agent for,
and to hold them harmless against, any loss, liability or expense reasonably
incurred without negligence or bad faith on their part arising out of or in
connection with actions taken or omitted by any of them in reliance on any
Officers' Certificate furnished pursuant to this Section 10.4.

         Section 10.5. Corporate Existence.
                       -------------------

         Subject to Article 8, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and rights (charter and statutory) and franchises; provided, however,
that the foregoing shall not obligate the Company to preserve any such right or
franchise if the Company shall determine that the preservation thereof is no
longer desirable in the conduct of its business and that the loss thereof is not
disadvantageous in any material respect to any Holder.

         Section 10.6. Waiver of Certain Covenants.
                       ---------------------------

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 10.5 with respect to the
Securities of any series if before the time for such compliance the Holders of
at least a majority in principal amount of the Outstanding Securities of such
series, by Act of such Holders, either shall waive such compliance in such
instance or generally shall have waived compliance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

         Section 10.7. Company and Guarantor's Statement as to Compliance;
                       ---------------------------------------------------
Notice of Certain Defaults.
--------------------------

         (1) The Company and the Guarantor shall deliver to the Trustee, within
120 days after the end of each fiscal year, a written statement (which need not
be contained in or accompanied by an Officers' Certificate) signed by the
principal executive officer, the principal financial officer or the principal
accounting officer of the Company or the Guarantor, as the case may be, stating
that

                  (a) a review of the activities of the Company or the
         Guarantor, as the case may be, during such year and of its performance
         under this Indenture has been made under his or her supervision, and

                  (b) to the best of his or her knowledge, based on such review,
         (a) the Company or the Guarantor, as the case may be, has complied with
         all the conditions and covenants imposed on it under this Indenture
         throughout such year, or, if there has been a default in the
         fulfillment of any such condition or covenant, specifying each such
         default known to

                                      -70-

<PAGE>

         him or her and the nature and status thereof, and (b) no event has
         occurred and is continuing which is, or after notice or lapse of time
         or both would become, an Event of Default, or, if such an event has
         occurred and is continuing, specifying each such event known to him
         and the nature and status thereof.

         (2) The Company shall deliver to the Trustee, within five days after
the occurrence thereof, written notice of any Event of Default or any event
which after notice or lapse of time or both would become an Event of Default
pursuant to clause (4) of Section 5.1.

         (3) The Trustee shall have no duty to monitor the Company's compliance
with the covenants contained in this Article 10 other than as specifically set
forth in this Section 10.7.

         Section 10.8. 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 any Outstanding
Original Issue Discount 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 Code, as amended from time to time.

                                   Article 11

                            REDEMPTION OF SECURITIES

         Section 11.1. Applicability of Article.
                       ------------------------

         Redemption of Securities of any series as permitted or required by the
terms of such Securities shall be made in accordance with the terms of such
Securities and (except as otherwise provided herein or pursuant hereto) this
Article.

         Section 11.2. Election to Redeem; Notice to Trustee.
                       -------------------------------------

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company of (a) less than all of the Securities of any series or (b) all
of the Securities of any series, with the same issue date, interest rate or
formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee in writing of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed.

         Section 11.3. Selection by Trustee of Securities to be Redeemed.
                       -------------------------------------------------

         If less than all of the Securities of any series with the same issue
date, interest rate or formula, Stated Maturity and other terms are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions of the principal amount of Registered
Securities of such series;

                                      -71-

<PAGE>

provided, however, that no such partial redemption shall reduce the portion of
the principal amount of a Registered Security of such series not redeemed to
less than the minimum denomination for a Security of such series established
herein or pursuant hereto.

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

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

         Unless otherwise specified in or pursuant to this Indenture or the
related Series Authorization of any series, if any Security selected for partial
redemption is converted into Common Stock of the Company or exchanged for other
securities in part before termination of the conversion or exchange right with
respect to the portion of the Security so selected, the converted portion of
such Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted or exchanged during a selection
of Securities to be redeemed shall be treated by the Trustee as Outstanding for
the purpose of such selection.

         Section 11.4. Notice of Redemption.
                       --------------------

         Notice of redemption shall be given in the manner provided in Section
1.6, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the Securities to be redeemed, to the Holders
of Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

         Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

         All notices of redemption shall state:

         (1) the Redemption Date,

         (2) the Redemption Price,

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

         (4) in case any Security is to be redeemed in part only, the notice
which relates to such Security shall state that on and after the Redemption
Date, upon surrender of such Security, the

                                      -72-

<PAGE>

Holder of such Security will receive, without charge, a new Security or
Securities of authorized denominations for the principal amount thereof
remaining unredeemed,

         (5) that, on the Redemption Date, the Redemption Price shall become due
and payable upon each such Security or portion thereof to be redeemed, in the
case of a Registered Security, together with any accrued interest and Additional
Amounts pertaining thereto, and that unless the Company shall default in the
payment of the Redemption Price and other amounts then due, interest thereon, if
applicable, shall cease to accrue on and after said date,

         (6) the place or places where such Securities, together (in the case of
Bearer Securities) with all Coupons appertaining thereto, if any, maturing on or
after the Redemption Date, are to be surrendered for payment of the Redemption
Price and any accrued interest and Additional Amounts pertaining thereto,

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

         (8) that, unless otherwise specified in such notice, Bearer Securities
of any series, if any, surrendered for redemption must be accompanied by all
Coupons maturing subsequent to the date fixed for redemption or the amount of
any such missing Coupon or Coupons will be deducted from the Redemption Price,
unless security or indemnity satisfactory to the Company, the Trustee and any
Paying Agent is furnished,

         (9) if Bearer Securities of any series are to be redeemed and no
Registered Securities of such series are to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption
on the Redemption Date pursuant to Section 3.5 or otherwise, the last date, as
determined by the Company, on which such exchanges may be made,

         (10) in the case of Securities of any series that are convertible into
Common Stock of the Company or exchangeable for other securities, the conversion
or exchange price or rate, the date or dates on which the right to convert or
exchange the principal of the Securities of such series to be redeemed will
commence or terminate and the place or places where such Securities may be
surrendered for conversion or exchange, and

         (11) the CUSIP number or the Euroclear or the Cedel reference numbers
of such Securities, if any (or any other numbers used by a Depository to
identify such Securities).

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

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

         Section 11.5. Deposit of Redemption Price.
                       ---------------------------

         On or prior to 10:00 a.m., New York City time, on any Redemption Date,
the Company shall deposit, with respect to the Securities of any series called
for redemption, with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 10.3) an amount of money in the applicable Currency sufficient to

                                      -73-

pay the Redemption Price of, and (except if the Redemption Date shall be an
Interest Payment Date, unless otherwise specified pursuant to Section 3.1 or in
the Securities of such series) any accrued interest on and Additional Amounts
with respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.

         Section 11.6. Securities Payable on Redemption Date.
                       -------------------------------------

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, become due and payable on the Redemption Date, at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and any accrued
interest or Additional Amounts) such Securities shall cease to bear interest and
the Coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void. Upon surrender of
any such Security for redemption in accordance with said notice, together with
all Coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with any accrued interest and Additional Amounts to the Redemption Date;
provided, however, that, except as otherwise provided in or pursuant to the
related Series Authorization and the Coupons, installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of Coupons for such interest (at an
Office or Agency located outside the United States except as otherwise provided
in Section 10.2), and provided, further, that, except as otherwise specified in
or pursuant to the related Series Authorization, installments of interest on
Registered Securities whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
Regular Record Dates therefor according to their terms and the provisions of
Section 3.7 and installments of interest on Registered Securities for which the
Redemption Date is after a Regular Record Date and on or before the following
Interest Payment 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 Regular Record Dates therefor according to their terms and the provisions of
Section 3.7.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing Coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an Office or
Agency for such Security located outside of the United States except as
otherwise provided in Section 10.2.

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

         Section 11.7. Securities Redeemed in Part.
                       ---------------------------

         Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (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 Registered Security or Securities of the
same series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

                                  SINKING FUNDS

         Section 12.1. Applicability of Article.
                       ------------------------

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or the related Series Authorization.

         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 such series is herein referred to as an "optional
                                                                    --------
sinking fund payment". If provided for by the terms of Securities of any series,
--------------------
the cash amount of any sinking fund payment

         may be subject to reduction as provided in Section 12.2. Each sinking
fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series and this Indenture.

         Section 12.2. Satisfaction of Sinking Fund Payments with Securities.
                       -----------------------------------------------------

         The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so
credited.

                                      -75-

<PAGE>

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

     Section 12.3. Redemption of Securities for Sinking Fund.
                   -----------------------------------------

     Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such

     Officers' Certificate shall specify an optional amount to be added in cash
to the next ensuing mandatory sinking fund payment, the Company shall thereupon
be obligated to pay the amount therein specified. Not less than 60 days before
each such sinking fund payment date the Trustee shall select the Securities to
be redeemed upon such sinking fund payment date in the manner specified in
Section 11.3 and cause notice of the redemption thereof to be given in the name
of and at the expense of the Company in the manner provided in Section 11.4.
Such notice having been duly given, the redemption of such Securities shall be
made upon the terms and in the manner stated in Section 11.6 and Section 11.7.

                                   Article 13

                       REPAYMENT AT THE OPTION OF HOLDERS

     Section 13.1. Applicability of Article.
                   ------------------------


     Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a written directive that such Securities
be cancelled. Notwithstanding anything to the contrary contained in this Section
13.1, in connection with any repayment of Securities, the Company may arrange
for the purchase of any Securities by an agreement with one or more

                                      -76-

<PAGE>

investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                                   Article 14

                        SECURITIES IN FOREIGN CURRENCIES

     Section 14.1. Applicability of Article.
                   ------------------------

     Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in

     the absence of any provision to the contrary in the form of Security of any
particular series or pursuant to this Indenture or the related Series
Authorization, any amount in respect of any Security denominated in a Currency
other than Dollars shall be treated for any such action or distribution as that
amount of Dollars that could be obtained for such amount on such reasonable
basis of exchange and as of the record date with respect to Registered
Securities of such series (if any) for such action, determination of rights or
distribution (or, if there shall be no applicable record date, such other date
reasonably proximate to the date of such action, determination of rights or
distribution) as the Company may specify in a written notice to the Trustee.

notice of such meeting within 21 days after receipt of such request (whichever

New York, or, if Securities of such series are to be issued as Bearer

In any other case the meeting may be adjourned for a period of not less than 10

notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage, which is less
than a majority, in principal amount of the Outstanding Securities of a series

                   ----------------------------------------------------------
Meetings.
--------

     (1) Notwithstanding any other provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of such series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding

written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 1.4 or other proof.

     (2) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 15.2(1), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

     (3) At any meeting, each Holder of a Security of such series or proxy shall
be entitled to one vote for each $1,000 principal amount of Securities of such
series held or represented by him; provided, however, that no vote shall be cast
or counted at any meeting in respect of any Security challenged as not
Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

     (4) Any meeting of Holders of Securities of any series duly called pursuant
to Section 15.2 at which a quorum is present may be adjourned from time to time
by Persons entitled to vote a majority in principal amount of the Outstanding
Securities of such series represented at the meeting; and the meeting may be

<PAGE>

Securities of such series or of their representatives by proxy and the principal
amounts and serial numbers of the Outstanding Securities of such series held or
represented by them. The permanent chairman of the meeting shall appoint two
inspectors of votes who shall count all votes cast at the meeting for or against
any resolution and who shall make and file with the secretary of the meeting
their verified written reports of all votes cast at the meeting. A record of the
proceedings of each meeting of Holders of Securities of any series shall be
prepared by the secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was given as provided in Section 15.2 and, if applicable, Section 15.4.
Each copy shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one such copy shall be delivered to
the Company, and another to the Trustee to be preserved by the Trustee, the
latter to have attached thereto the ballots voted at the meeting. Any record so
signed and verified shall be conclusive evidence of the matters therein stated.
