        The Company has duly authorized the execution and delivery of this
Indenture to provide for the issuance from time to time of its unsecured,

               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 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.

               (2) 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
with respect to any of the matters referred to in this Section.

               (3) 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.

               (4) 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 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.

               (5) 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


                                      -12-
<PAGE>

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.

               (6) 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. TO THE TRUSTEE AND THE COMPANY.

        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 Chief Financial Officer, Controller or
Secretary, 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,
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 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


                                      -13-
<PAGE>

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

SECTION 1.8.   CONFLICT WITH TRUST INDENTURE ACT.

        If any provision hereof limits, qualifies or conflicts with 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.

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

SECTION 1.10.  SUCCESSORS AND ASSIGNS.

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

SECTION 1.11.  SEPARABILITY CLAUSE.

        In case any provision in this Indenture, 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
Registrar, any Paying Agent, any Authenticating Agent and their successors
hereunder, the holders of Senior Indebtedness 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.

        This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
state.

SECTION 1.14.  LEGAL HOLIDAYS.

        Unless otherwise specified in or pursuant to this Indenture or any
Securities, 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 be a Legal Holiday 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 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.

        This Indenture may be executed in several counterparts, each of which
shall be an original and all of which shall constitute but one and the same
instrument.

SECTION 1.16.  JUDGMENT CURRENCY.

        The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
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
Judgment 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


                                      -15-
<PAGE>

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 foregoing, "New York Banking Day" means any
day except a Saturday, Sunday or a legal holiday in The City of New York or a
day on which banking institutions in The City of New York are authorized or
obligated by law, regulation or executive order to be closed.

SECTION 1.17.  NO SECURITY INTEREST CREATED.

        Subject to the provisions of Section 10.5, nothing in this Indenture or
in any Security, express or implied, shall be construed to constitute a security
interest under the Uniform Commercial Code or similar legislation, as now or
hereafter enacted and in effect in any jurisdiction where property of the
Company or its Subsidiaries is or may be located.

SECTION 1.18.  LIMITATION ON INDIVIDUAL LIABILITY.

        No recourse under or upon any obligation, covenant or agreement
contained in this Indenture or in any Security, or for any claim based thereon
or otherwise in respect thereof, shall be had against any incorporator, officer
or director, as such, past, present or future, of the Company, either directly
or through the Company, whether by virtue of any constitution, statute or rule
of law, or by the enforcement of any assessment or penalty or 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 Indenture
or in any Security or implied therefrom; and that any and all such personal
liability of every name and nature, either at common law or in equity or by
constitution or statute, of, and any and all such rights and claims against,
every such incorporator, shareholder, officer or director, as such, because of
the creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or in any
Security or implied therefrom, are hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issuance of such Security.

SECTION 2.1.   FORMS GENERALLY.

SECTION 2.3.   SECURITIES IN GLOBAL FORM.

        Unless otherwise provided in or pursuant to this Indenture or any
Securities, the Securities 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 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
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 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 but need not be
accompanied by or contained in an Officer's Certificate and need not be
accompanied by an Opinion of Counsel.


                                      -17-

        Notwithstanding the provisions of Section 3.7, unless otherwise
specified in or pursuant to this Indenture or any Security, payment of principal

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

specified pursuant to Section 3.1.

which shall be subject to covenant defeasance, and any deletions from, or
modifications or additions to, the provisions of Article 4 in respect of the
Securities of such series;


                                      -20-
<PAGE>

               (20) whether any of such Securities are to be issuable upon the
exercise of warrants, and the time, manner and place for such Securities to be
authenticated and delivered;

               (21) if any of such Securities are to be issuable in global
form and are to be issuable in definitive form (whether upon original issue or
upon exchange of a temporary Security) only upon receipt of certain certificates
or other documents or satisfaction of other conditions, then the form and terms
of such certificates, documents or conditions;

               (22) if there is more than one Trustee, the identity of the
Trustee and, if not the Trustee, the identity of each Security Registrar, Paying
Agent or Authenticating Agent with respect to such Securities;

               (23) any deletions from or modifications or additions to the
provisions of Article 16 in respect of any of such Securities; and

               (24) any other terms of such Securities and any other deletions
from or modifications or additions to this Indenture in respect of such
Securities.

        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 Officer's 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 Officer's Certificate or
supplemental indenture and that such persons are authorized to determine,
consistent with such Officer's Certificate or any applicable supplemental
indenture, such terms and conditions of the Securities of such series as are
specified in such Officer's 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 Officer's
Certificate setting forth the terms of such series.

        The Securities shall be subordinated in right of payment to Senior
Indebtedness as provided in Article 16.

SECTION 3.2.   CURRENCY; DENOMINATIONS.

        Unless otherwise provided in or pursuant to this Indenture, 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, 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


                                      -21-
<PAGE>

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.

SECTION 3.3.   EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

        Securities shall be executed on behalf of the Company by its Chairman of
the Board, its President, its Chief Financial Officer, its Controller or a Vice
President under its corporate seal reproduced thereon and attested by its
Secretary or one of its Assistant Secretaries. Coupons shall be executed on
behalf of the Company by the President, Chief Financial Officer, Controller or
Treasurer 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 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 Officer's 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 relying upon,

               (1) an Opinion of Counsel to the effect that:

                      (a) the form or forms and terms of such Securities and
Coupons, if any, have been established in conformity with the provisions of this
Indenture;

                      (b) all conditions precedent to the authentication and
delivery of such Securities and Coupons, if any, appertaining thereto, have been
complied with and that such Securities and Coupons, when completed by
appropriate insertions, executed under the Company's corporate seal and attested
by duly authorized officers of the Company, delivered by duly authorized
officers of the Company to the Trustee for authentication pursuant to this
Indenture, and authenticated and delivered by the Trustee and issued by the
Company in the manner and subject to any conditions specified in such Opinion of
Counsel, will constitute legally valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, except as
enforcement thereof may be subject to or limited by bankruptcy, insolvency,
reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent
transfer or other similar laws relating to or affecting creditors' rights
generally, and subject to general principles of equity (regardless of whether
enforcement is sought in a proceeding in equity or at law) and will entitle the
Holders thereof to the benefits of this Indenture; such Opinion of Counsel need
express no opinion as to the availability of equitable remedies;


                                      -22-
<PAGE>

                      (c) all laws and requirements in respect of the execution
and delivery by the Company of such Securities and Coupons, if any, have been
complied with; and

                      (d) this Indenture has been qualified under the Trust
Indenture Act; and

               (2) an Officer's Certificate stating that, to the best knowledge
of the Persons executing such certificate, all conditions precedent to the
execution, authentication and delivery of such Securities and Coupons, if any,
appertaining thereto, have been complied with, and 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 Officer's
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 and that no Event of Default with
respect to any of the Securities has occurred or is continuing.

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

        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 this Indenture.

        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 6.12 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 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, in bearer form with one or more Coupons or without Coupons and with
such


                                      -23-
<PAGE>

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 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,
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. Unless otherwise provided in or
pursuant to this Indenture 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 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 Securities, 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, of a
like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.


                                      -24-
<PAGE>

        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, 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 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. 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 with respect to Securities
of any series, 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 with respect to such series.

        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.


                                      -25-
<PAGE>

        Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture, 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, 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 Officer's 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 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) 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 any 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) 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.


                                      -26-
<PAGE>

        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, 9.5 or 11.7 not involving any transfer.

        Except as otherwise provided in or pursuant to this Indenture, 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 11.3 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 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
bona fide 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


                                      -27-
<PAGE>

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, 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.

        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) 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, 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, 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, as provided in
clause (1) or (2) below:


                                      -28-
<PAGE>

               (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 for the benefit of the Person
entitled to such Defaulted Interest as provided in this clause (1). 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. The Trustee may, in its discretion, in the name and at the expense
of the Company, cause a similar notice to be published at least once in an
Authorized Newspaper 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 notice given by the Company to the Trustee
of the proposed payment pursuant to this clause (2), such payment shall be
deemed practicable by the Trustee.

        Unless otherwise provided in or pursuant to this Indenture or the
Securities 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
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 other securities of the Company or exchangeable for securities of another
issuer, 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


                                      -29-

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 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. 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.

SECTION 3.10.  COMPUTATION OF INTEREST.

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

                     SATISFACTION AND DISCHARGE OF INDENTURE

SECTION 4.1.   SATISFACTION AND DISCHARGE.

        Upon the direction of the Company by a Company Order, this Indenture
shall cease to be of further effect, and the provisions of Article 16 shall
cease to be effective, 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

               (1) either

                      (a) all Securities of such series theretofore
authenticated and delivered and all Coupons appertaining thereto (other than (i)
Coupons appertaining to Bearer Securities of such series surrendered in exchange
for Registered Securities of such series and maturing after such exchange whose
surrender is not required or has been waived as provided in Section 3.5, (ii)
Securities and Coupons of such series which have been destroyed, lost or stolen
and which have been replaced or paid as provided in Section 3.6, (iii) Coupons
appertaining to Securities of such series called for redemption and maturing
after the relevant Redemption Date whose surrender has been waived as provided
in Section 11.7, and (iv) Securities and Coupons of such series for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter repaid to the Company or discharged from
such trust, as provided in Section 10.3) have been delivered to the Trustee for
cancellation; or

                      (b) all Securities of such series and, in the case of (i)
or (ii) below, any Coupons appertaining thereto not theretofore delivered to the
Trustee for cancellation, (i) have become due and payable, or (ii) will become
due and payable at their Stated Maturity within one year, or (iii) if redeemable
at the option of the Company, are to be called for redemption within one year
under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company, and
the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to
be deposited with the Trustee as trust funds in trust for such purpose, money in
the Currency in which such Securities are payable in an amount sufficient to pay
and discharge the entire indebtedness on such Securities and any Coupons
appertaining thereto not theretofore delivered to the Trustee for cancellation,
including the principal of, any premium and interest on, and any Additional
Amounts with respect to such Securities and any Coupons appertaining thereto, to
the date of such deposit (in the case of Securities which have become due and
payable) or to the Maturity thereof, as the case may be;

               (2) the Company has paid or caused to be paid all other sums
payable hereunder by the Company with respect to the Outstanding Securities of
such series and any Coupons appertaining thereto; and


                                      -31-
<PAGE>

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

        In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

        Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 6.7 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations
of the Company and the Trustee with respect to the Securities of such series
under Sections 3.5, 3.6, 4.3, 10.2 and 10.3, with respect to the payment of
Additional Amounts, if any, with respect to such Securities as contemplated by
Section 10.4 (but only to the extent that the Additional Amounts payable with
respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 4.1(1)(b)), and with respect to any
rights to convert or exchange such Securities into securities of the Company or
another issuer shall survive.

SECTION 4.2.   DEFEASANCE AND COVENANT DEFEASANCE.

               (1) Unless pursuant to Section 3.1, either or both of (i)
defeasance of the Securities of or within a series under clause (2) of this
Section 4.2 shall not be applicable with respect to the Securities of such
series or (ii) covenant defeasance of the Securities of or within a series under
clause (3) of this Section 4.2 shall not be applicable with respect to the
Securities of such series, then such provisions, together with the other
provisions of this Section 4.2 (with such modifications thereto as may be
specified pursuant to Section 3.1 with respect to any Securities), shall be
applicable to such Securities and any Coupons appertaining thereto, and the
Company may at its option by Board Resolution, at any time, with respect to such
Securities and any Coupons appertaining thereto, elect to have Section 4.2(2) or
Section 4.2(3) be applied to such Outstanding Securities and any Coupons
appertaining thereto upon compliance with the conditions set forth below in this
Section 4.2.

               (2) Upon the Company's exercise of the above option applicable to
this Section 4.2(2) with respect to any Securities of or within a series, the
Company shall be deemed to have been discharged from its obligations, and the
provisions of Article 16 shall cease to be effective, with respect to such
Outstanding Securities and any Coupons appertaining thereto on the date the
conditions set forth in clause (4) of this Section 4.2 are satisfied
(hereinafter, "defeasance"). For this purpose, such defeasance means that the
Company shall be deemed to have paid and discharged the entire Indebtedness
represented by such Outstanding Securities and any Coupons appertaining thereto,
which shall thereafter be deemed to be "Outstanding" only for the purposes of
clause (5) of this Section 4.2 and the other Sections of this Indenture referred
to in clauses (i) and (ii) below, and to have satisfied all of its other
obligations under such Securities and any Coupons appertaining thereto, and this
Indenture insofar as such Securities and any Coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (i) the rights of
Holders of such Outstanding Securities and any Coupons appertaining thereto to
receive, solely from the trust fund described in clause (4) of this Section 4.2
and as more fully set forth in such


                                      -32-
<PAGE>

clause, payments in respect of the principal of (and premium, if any) and
interest, if any, on, and Additional Amounts, if any, with respect to, such
Securities and any Coupons appertaining thereto when such payments are due, and
any rights of such Holder to convert such Securities into other securities of
the Company or exchange such Securities for securities of another issuer, (ii)
the obligations of the Company and the Trustee with respect to such Securities
under Sections 3.5, 3.6, 10.2 and 10.3 and with respect to the payment of
Additional Amounts, if any, on such Securities as contemplated by Section 10.4
(but only to the extent that the Additional Amounts payable with respect to such
Securities exceed the amount deposited in respect of such Additional Amounts
pursuant to Section 4.2(4)(a) below), and with respect to any rights to convert
such Securities into other securities of the Company or exchange such Securities
for securities of another issuer, (iii) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (iv) this Section 4.2. The Company may
exercise its option under this Section 4.2(2) notwithstanding the prior exercise
of its option under clause (3) of this Section 4.2 with respect to such
Securities and any Coupons appertaining thereto.

               (3) Upon the Company's exercise of the option to have this
Section 4.2(3) apply with respect to any Securities of or within a series, the
Company shall be released from its obligations under Sections 10.5 and 10.6,
and, to the extent specified pursuant to Section 3.1(19), any other covenant
applicable to such Securities, and the provisions of Article 16 shall cease to
be effective as it relates to the aforementioned obligations and covenants, with
respect to such Outstanding Securities and any Coupons appertaining thereto, on
and after the date the conditions set forth in clause (4) of this Section 4.2
are satisfied (hereinafter, "covenant defeasance"), and such Securities and any
Coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any direction, waiver, consent or declaration or Act of
Holders (and the consequences of any thereof) in connection with any such
obligation or covenant, but shall continue to be deemed "Outstanding" for all
other purposes hereunder. For this purpose, such covenant defeasance means that,
with respect to such Outstanding Securities and any Coupons appertaining
thereto, the Company may omit to comply with, and shall have no liability in
respect of, any term, condition or limitation set forth in any such Section or
such other covenant, or Article, whether directly or indirectly, by reason of
any reference elsewhere herein to any such Section or such other covenant, or
Article, or by reason of reference in any such Section or such other covenant,
or Article, to any other provision herein or in any other document and such
omission to comply shall not constitute a default or an Event of Default under
Section 5.1(4) or 5.1(8) or otherwise, as the case may be, but, except as
specified above, the remainder of this Indenture and such Securities and Coupons
appertaining thereto shall be unaffected thereby.

               (4) The following shall be the conditions to application of
clause (2) or (3) of this Section 4.2 to any Outstanding Securities of or within
a series and any Coupons appertaining thereto:

                      (a) The Company shall irrevocably have deposited or caused
to be deposited with the Trustee (or another trustee satisfying the requirements
of Section 6.8 who shall agree to comply with the provisions of this Section 4.2
applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any Coupons appertaining
thereto, (1) an amount in Dollars or in such Foreign Currency in which such
Securities and any Coupons appertaining thereto are then specified as payable at
Stated Maturity, or (2) Government Obligations applicable to such Securities and
Coupons appertaining thereto (determined on the basis of the Currency in which
such Securities and Coupons appertaining thereto are then specified as payable
at Stated Maturity) which through the scheduled payment of principal and
interest in respect thereof in accordance with their


                                      -33-
<PAGE>

terms will provide, not later than one day before the due date of any payment of
principal of (and premium, if any) and interest, if any, on 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 expressed in a written
certification thereof delivered to the Trustee, to pay and discharge, and which
shall be applied by the Trustee (or other qualifying trustee) to pay and
discharge, (y) the principal of (and premium, if any) and interest, if any, on
such Outstanding Securities and any Coupons appertaining thereto at the Stated
Maturity of such principal or installment of principal or premium or interest
and (z) any mandatory sinking fund payments or analogous payments applicable to
such Outstanding Securities and any Coupons appertaining thereto on the days on
which such payments are due and payable in accordance with the terms of this
Indenture and of such Securities and any Coupons appertaining thereto.

                      (b) Such defeasance or covenant defeasance shall not
result in a breach or violation of, or constitute a default under, this
Indenture or any other material agreement or instrument to which the Company is
a party or by which it is bound.

                      (c) No Event of Default or event which with notice or
lapse of time or both would become an Event of Default with respect to such
Securities and any Coupons appertaining thereto shall have occurred and be
continuing on the date of such deposit and, with respect to defeasance only, at
any time during the period ending on the 123rd day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied
until the expiration of such period).

                      (d) In the case of an election under clause (2) of this
Section 4.2, the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (i) the Company 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, the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect 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 covenant 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 covenant defeasance had not occurred.

                      (f) The Company shall have delivered to the Trustee an
Opinion of Counsel to the effect that, after the 123rd day after the date of
deposit, all money and Government Obligations (or other property as may be
provided pursuant to Section 3.1) (including the proceeds thereof) deposited or
caused to be deposited with the Trustee (or other qualifying trustee) pursuant
to this clause (4) to be held in trust will not be subject to any case or
proceeding (whether voluntary or involuntary) in respect of the Company under
any Federal or State bankruptcy, insolvency,

                                      -34-
<PAGE>

reorganization or other similar law, or any decree or order for relief in
respect of the Company issued in connection therewith.

                      (g) At the time of the deposit, (i) no default in the
payment of any principal of, premium, if any, or interest on any Senior
Indebtedness shall have occurred and be continuing, (ii) no event of default
with respect to any Senior Indebtedness shall have resulted in such Senior
Indebtedness becoming, and continuing to be, due and payable prior to the date
on which it would otherwise have become due and payable (unless payment of such
Senior Indebtedness has been made or duly provided for), and (iii) no other
event of default with respect to any Senior Indebtedness shall have occurred and
be continuing permitting (after notice or lapse of time or both) the holders of
such Senior Indebtedness (or a trustee on behalf of such holders) to declare
such Senior Indebtedness due and payable prior to the date on which it would
otherwise have become due and payable.

                      (h) The Company shall have delivered to the Trustee an
Officer's Certificate and the Company shall have delivered to the Trustee an
Opinion of Counsel, each stating that all conditions precedent to the defeasance
or covenant defeasance under clause (2) or (3) of this Section 4.2 (as the case
may be) have been complied with.

                      (i) Notwithstanding any other provisions of this Section
4.2(4), such defeasance or covenant defeasance shall be effected in compliance
with any additional or substitute terms, conditions or limitations which may be
imposed on the Company in connection therewith pursuant to Section 3.1.

               (5) Unless otherwise specified in or pursuant to this Indenture
or any Security, if, after a deposit referred to in Section 4.2(4)(a) has been
made, (a) the Holder of a Security in respect of which such deposit was 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 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.

        The Company 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.


                                      -35-
<PAGE>

        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, 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 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. Money and Government
Obligations so held in trust shall not be subject to the provisions of Article
16 except to the extent set forth in Section 16.1.

SECTION 4.4.   REINSTATEMENT.

        If the Trustee or any Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 4.2(2) or 4.2(3) shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 4.3 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Securities
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

SECTION 5.1.   EVENTS OF DEFAULT.

any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be occasioned by the provisions of Article
16 or be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body), unless such event is specifically
deleted or modified in or

<PAGE>

pursuant to the supplemental indenture, Board Resolution or Officer's
Certificate establishing the terms of such Series pursuant to this Indenture:

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

               (2) default in the payment of the principal of or any premium on
any Security of such series, or any Additional Amounts payable with respect

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

               (4) default in the performance, or breach, of any covenant or
warranty of the Company in this Indenture or the Securities (other than a
covenant or warranty a default in the performance or the breach of which is
elsewhere in this Section specifically dealt with or which has been expressly
included in this Indenture solely for the benefit of a series of Securities
other than such series), and continuance of such default or breach for a period
of 60 days after there has been given, by registered or certified mail, to the
Company by the Trustee or to the Company and the Trustee by the Holders of at
least 25% in principal amount of the Outstanding Securities of such series, a
written notice specifying such default or breach and requiring it to be remedied
and stating that such notice is a "Notice of Default" hereunder; or

               (5) if any event of default as defined in any mortgage, indenture
or instrument under which there may be issued, or by which there may be secured
or evidenced, any Indebtedness of the Company or any Restricted Subsidiary
(including, in each case, an Event of Default under any other series of
Securities), whether such Indebtedness now exists or shall hereafter be created
or incurred, shall happen and shall consist, in the aggregate, of the default in
the payment of $25,000,000 or more in principal amount of such Indebtedness at
the maturity thereof (after giving effect to any applicable grace period) or
shall, in the aggregate, result in such Indebtedness in principal amount of
$25,000,000 or more becoming or being declared due and payable prior to the date
on which it would otherwise become due and payable, and such default shall not
be cured or such acceleration shall not be rescinded, stayed or annulled or, in
the case of Indebtedness contested in good faith by the Company, a bond, letter
of credit, escrow deposit or other cash equivalent in an amount sufficient to
discharge such Indebtedness having been set aside by the Company, in each case
within a period of 10 days after there shall have been given, by registered or
certified mail, to the Company by the Trustee or to the Company and the Trustee
by the Holders of at least 25% in principal amount of the Outstanding Securities
of such series, a written notice specifying such event of default and requiring
the Company to cause such acceleration to be rescinded or annulled or to cause

SECTION 5.2.   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

        If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (6) or (7)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.

        If an Event of Default specified in clause (6) or (7) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

        At any time after a declaration of acceleration with respect to the
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

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


                                      -38-
<PAGE>

                      (a) all overdue installments of any interest on and
Additional Amounts with respect to all Securities of such series and any Coupon
appertaining thereto,

                      (b) the principal of and any premium on any Securities of
such series which have become due otherwise than by such declaration of
acceleration and interest thereon and any Additional Amounts with respect
thereto at the rate or rates borne by or provided for in such Securities,

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

                      (d) all sums paid or advanced by the Trustee hereunder and
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and all other amounts due the Trustee under
Section 6.7; and

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

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

SECTION 5.3.   COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

        The Company covenants that if

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

               (2) default is made in the payment of the principal of or 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 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 any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and all other
amounts due to the Trustee under Section 6.7.

        If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
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


                                      -39-
<PAGE>

against the Company 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 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.

SECTION 5.4.   TRUSTEE MAY FILE PROOFS OF CLAIM.

        In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities of any series or the property of the Company or such other obligor or
their creditors, the Trustee (irrespective of whether the principal of the
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities or any Coupons to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities or any Coupons, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 6.7.

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

SECTION 5.5.   TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES OR
               COUPONS.

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

SECTION 5.6.   APPLICATION OF MONEY COLLECTED.

        Subject to Article 16, any money collected by the Trustee pursuant to
this Article shall be applied in the following order, at the date or dates fixed
by the Trustee and, in case of the distribution of such money on account of
principal, or any premium, interest or Additional Amounts, upon presentation of
the Securities or Coupons, or both, as the case may be, and the notation thereon
of the payment if only partially paid and upon surrender thereof if fully paid:

        FIRST: To the payment of all amounts due the Trustee and any predecessor
Trustee under Section 6.7;

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

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

SECTION 5.7.   LIMITATIONS ON SUITS.

        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



                                      -41-
<PAGE>

               (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.

SECTION 5.8.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND ANY
               PREMIUM, INTEREST AND ADDITIONAL AMOUNTS.

        Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
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 in or pursuant to this Indenture, 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 proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and 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.

SECTION 5.10.  RIGHTS AND REMEDIES CUMULATIVE.

        Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities or Coupons in the last
paragraph of Section 3.6, no right or remedy herein conferred upon or reserved
to the Trustee or to each and every Holder of a Security or a Coupon is intended
to be 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
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

<PAGE>

SECTION 5.11.  DELAY OR OMISSION NOT WAIVER.

        No delay or omission of the Trustee or of any Holder of any 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.

SECTION 5.12.  CONTROL BY HOLDERS OF SECURITIES.

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

SECTION 5.13.  WAIVER OF PAST DEFAULTS.

        The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series 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, on or after the date
for repayment) or for the enforcement of the right, if any, to convert or
exchange any Security into other securities in accordance with its terms.

conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but in the case of
any such certificates or opinions that by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Indenture but not to verify or confirm the contents thereof.

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

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

of paragraph (a) of this Section 6.1;

satisfactory to it against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction;

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

debenture, coupon or other paper or document, but the Trustee, in its
discretion, may, but shall not be obligated to make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee

respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series entitled to receive reports pursuant to
Section 7.3(3), notice of such default hereunder actually known to a Responsible
Officer of the Trustee, unless such default shall have been cured or waived;
provided, however, that, except in the case of a default in the payment of the
principal of (or premium, if any), or interest, if any, on, or Additional
Amounts or any sinking fund or purchase fund installment with respect to, any
Security of such series, the Trustee shall be protected in withholding such

faith determine that the withholding of such notice is in the best interest of
the Holders of Securities and Coupons of such series; and provided, further,
that in the case of any default of the character specified in Section 5.1(5)
with respect to Securities of such series, no such notice to Holders shall be

SECTION 6.7.   COMPENSATION AND REIMBURSEMENT.

        The Company agrees:

               (1) to pay to the Trustee from time to time reasonable

compensation of a trustee of an express trust);

               (2) except as otherwise expressly provided herein, to reimburse

claim or liability in connection with the exercise or performance of any of
their powers or duties hereunder, except to the extent that any such loss,

this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of, and premium or
interest on or any Additional Amounts with respect to Securities or any Coupons
appertaining thereto.

predecessor Trustee but the negligence or bad faith of any Trustee shall not
affect the rights of any other Trustee under this Section 6.7.

discharge of this Indenture or the earlier resignation or removal of the Trustee

               (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 6.10 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 of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and the
Company.

               (4) If at any time:

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

himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities of
such series and the appointment of a successor Trustee or Trustees.

               (5) If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of Trustee for any cause,
with respect to the Securities of one or more series, the Company, by or
pursuant to a Board Resolution, shall promptly appoint a successor Trustee or

any such successor Trustee may be appointed with respect to the Securities of
one or more or all of such series and that at any time there shall be only one

after such resignation, removal or incapacity, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance


                                      -49-
<PAGE>

with the applicable requirements of Section 6.10, become the successor Trustee

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

removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by mailing written notice of such event by first-class mail, postage prepaid, to
the Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are
issued as Bearer Securities, by publishing notice of such event once in an
Authorized Newspaper in each Place of Payment located outside the United States.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

               (7) In no event shall any retiring Trustee be liable for the acts
or omissions of any successor Trustee hereunder.

SECTION 6.10.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

               (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 duties hereunder of the retiring Trustee; but, on the request
of the 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
successor Trustee all property and money held by such retiring Trustee
hereunder, subject nevertheless to its claim, if any, provided for in Section
6.7.

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 retiring Trustee with respect to the Securities of that or those series
as to which the retiring Trustee is not retiring shall continue to be vested in
the retiring Trustee, and (3) shall add to or change any of the provisions of
this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-



                                      -50-
<PAGE>

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
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates; but, on
request of the Company or such successor Trustee, such retiring Trustee, upon
payment of its charges with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates and subject to Section
10.3 shall duly assign, transfer and deliver to such successor Trustee, to the
extent contemplated by such supplemental indenture, the property and money held
by such retiring Trustee hereunder with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates, subject
to its claim, if any, provided for in Section 6.7.

               (3) Upon request of any Person appointed hereunder as a successor
Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts referred to in paragraph (1) or (2) of this Section, as the
case may be.

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

SECTION 6.11.  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 by sale or otherwise to all or substantially all of the
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 6.12.  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


                                      -51-
<PAGE>

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, 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 by sale or otherwise 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 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. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 6.7.

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


                                      -52-
<PAGE>

        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.

                                              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 Officer's 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.

successor Person had been named as the Company herein; and thereafter, except in
the case of a lease, the predecessor Person shall be released from all
obligations and covenants under this Indenture, the Securities and the Coupons.

SECTION 9.2.   SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

        With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company (when authorized by or pursuant to a Company's Board
Resolution) and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of
modifying in any manner the rights of the Holders of Securities of such series

otherwise, or change the obligation of the Company to pay Additional Amounts
pursuant to the terms hereof (except as contemplated by Section 8.1(1) and
permitted by Section 9.1(1)), or reduce the amount of the principal of an
Original Issue Discount Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 5.2 or
the amount thereof provable in


                                      -57-

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

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

SECTION 9.3.   EXECUTION OF SUPPLEMENTAL INDENTURES.

protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture and an
Officer's Certificate stating that all conditions precedent to the execution of
such supplemental indenture have been fulfilled. The Trustee may, but shall not
be obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

<PAGE>

SECTION 9.4.   EFFECT OF SUPPLEMENTAL INDENTURES.

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

SECTION 9.5.   REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

SECTION 9.6.   CONFORMITY WITH TRUST INDENTURE ACT.

        Every supplemental indenture executed pursuant to this Article shall

        Promptly after the execution by the Company and the Trustee of any

setting forth the substance of such supplemental indenture.

                                   ARTICLE 10.
                                    COVENANTS

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


                                      -59-
<PAGE>

such series relating thereto and this Indenture may be served. If Securities of
a series are issuable as Bearer Securities, the Company 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 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, 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, 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 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, 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.


                                      -60-
<PAGE>

        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 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 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 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 or 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 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;

               (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, 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


                                      -61-
<PAGE>

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 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, may at the expense of the Company 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 and 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.

        If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest 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 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
Securities of the applicable series, if the Securities of a series provide for
the payment of Additional Amounts, at least 10 days prior to the first Interest
Payment Date with respect to 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 Officer's Certificate, the Company
shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if
other than the Trustee, an Officer's Certificate instructing the Trustee and
such Paying Agent or Paying Agents whether such payment of principal of and
premium, if any, or interest on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series. If any such withholding shall be required, then such Officer's


                                      -62-
<PAGE>

Certificate shall specify by country 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 the terms of such Securities. 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 Officer's Certificate furnished pursuant to this
Section 10.4.

SECTION 10.5.  LIMITATION ON MORTGAGES AND LIENS.

        The Company will not at any time directly or indirectly issue, assume,
guarantee or permit to exist any indebtedness secured by a mortgage, pledge,
lien or other encumbrance (any mortgage, pledge, lien or other encumbrance being
hereinafter in this Section referred to as a "lien") on any of its property or
assets or any property or assets of a Restricted Subsidiary, whether now owned
or hereafter acquired, without making effective provisions whereby the
Securities then outstanding (and, if the Company so elects, any other
indebtedness ranking on a parity with the Securities) shall be equally and
ratably secured with any such secured indebtedness, so long as any such other
indebtedness shall be secured; provided, however, that the foregoing covenant
shall not be applicable to the following:

               (1) liens in existence on the date of this Indenture; or

               (2) liens on real estate (including liens existing in respect of
such real estate at the time of acquisition thereof) securing indebtedness in an
amount not in excess of 100% of the fair value of the real estate at the time of
creation of such indebtedness (as determined by the Board of Directors); or

               (3) liens arising from the acquisition of a business as a going
concern (whether by merger, acquisition of a controlling stock interest,
acquisition of assets or otherwise) or to which assets acquired by the Company
or a Restricted Subsidiary in partial or complete satisfaction of secured
indebtedness are subject; or

               (4) liens to secure the extension, renewal or replacement of any
indebtedness secured by any of the liens referred to in (1), (2) or (3) above,
provided that there shall not be an increase in the amount of indebtedness
secured by such extension, renewal or replacement; or

               (5) liens of taxes or assessments or governmental charges or
levies not then due and delinquent or the validity of which is being contested
in good faith or which are less than $10,000,000 in amount; pledges or deposits
to secure public or statutory obligations including liens and deposits required
or provided for under state insurance laws and similar regulatory statutes;
materialmen's, mechanics', carrier's, workmen's, repairmen's or other like
liens, and pledges or deposits made in the ordinary course of business to obtain
the release of such liens; liens created by or resulting from any litigation or
legal proceeding which is being contested in good faith by appropriate
proceedings or which involve claims of less than $10,000,000; deposits to secure
(or in lieu of) surety, stay, appeal or customs bonds; deposits to secure the
payment of taxes, assessments, customs duties or other similar charges;
landlords liens on property held under lease; and any other liens similar to
those described in this clause (5), the existence of which does not, in the
opinion of the Company, materially impair the use by the Company or the
Restricted Subsidiary of the affected property in the operation of its business,
or the value of such property for the purpose of such business.



                                      -63-

SECTION 10.6.  LIMITATION UPON SALES OF CAPITAL STOCK OF RESTRICTED
               SUBSIDIARIES.

        The Company will not sell, transfer or otherwise dispose of (except to a
Restricted Subsidiary), and it will not permit any Restricted Subsidiary to
sell, transfer or otherwise dispose of (except to the Company or to a Restricted
Subsidiary), all or any portion of the shares of Capital Stock of a Restricted
Subsidiary, unless such Capital Stock shall be disposed of for a consideration
consisting of cash or other property, which, in the opinion of the Board of
Directors, is at least equal to the fair value thereof.

        For the purposes of this Indenture, "Restricted Subsidiary" shall mean a
Subsidiary including Subsidiaries of any Subsidiary, which meets any of the
following conditions:

               (1) the Company's and its other Subsidiaries' investments in and
advances to the Subsidiary exceed 10% of the total assets of the Company and its
Subsidiaries consolidated as of the end of the most recently completed fiscal
year; or

               (2) the Company's and its other Subsidiaries' proportionate share
of the total assets (after inter-company eliminations) of the Subsidiary exceeds
10% of the total assets of the Company and its Subsidiaries consolidated as of
the end of the most recently completed fiscal year; or

               (3) the Company's and its other Subsidiaries' equity in the
income from continuing operations before income taxes, extraordinary items and
cumulative effect of a change in accounting principle of the Subsidiary exceeds
10% of such income of the Company and its Subsidiaries consolidated for the most
recently completed fiscal year.

        For purposes of making the prescribed income test in clause (3) of the
preceding sentence, when a loss has been incurred by either the Company and its
Subsidiaries consolidated or the tested Subsidiary, but not both, the equity in
the income or loss of the tested subsidiary shall be excluded from the income of
the Company and its Subsidiaries consolidated for purposes of the computation
and if income of the Company and its Subsidiaries consolidated for the most
recent fiscal year is at least 10% lower than the average of the income for the
last five years, such average income shall be substituted for purposes of the
computation and any loss years shall be omitted for purposes of computing
average income.

SECTION 10.7.  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 that of each of its Restricted Subsidiaries and their respective
rights (charter and statutory) and franchises; provided, however, that the
foregoing shall not obligate the Company or any of its Restricted Subsidiaries
to preserve any such right or franchise if the Company or any such Restricted
Subsidiary shall determine that the preservation thereof is no longer desirable
in the conduct of its business or the business of such Restricted Subsidiary and
that the loss thereof is not disadvantageous in any material respect to any
Holder.

SECTION 10.8.  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, 10.6 or 10.7 with respect to
the Securities of any series if before the


                                      -64-
<PAGE>

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.

officer of the Company, stating that

                      (a) a review of the activities of the Company 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 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 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

               (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 10.9.

                                   ARTICLE 11.
                            REDEMPTION OF SECURITIES

SECTION 11.1.  APPLICABILITY OF ARTICLE.

        Redemption of Securities of any series at the option of the Company 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),


                                      -65-
<PAGE>

notify the Trustee 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.

        Unless otherwise specified as contemplated by Section 3.1, 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;
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
Securities of any series, if any Security selected for partial redemption is
converted into other securities of the Company or exchanged for securities of
another issuer 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,


                                      -66-
<PAGE>

               (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 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, and, if applicable, that interest thereon 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 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 to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 11.5.  DEPOSIT OF REDEMPTION PRICE.

        On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 11.4, 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 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, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest 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 this Indenture or the Bearer Securities
of such series, 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
this Indenture or the Registered Securities of such series, 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.

        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 any Security of such series issued
pursuant to this Indenture.

        The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such 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. 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 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 Officer's
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 Officer's 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 Sections 11.6 and 11.7.

                       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 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
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.

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 Securities, 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.

SECTION 15.1.  PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

        A meeting of Holders of Securities of any series may be called at any
time and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities

Securities of any series for any purpose specified in Section 15.1, to be held
at such time and at such place in the Borough of Manhattan, The City of New
York, or, if Securities of such series have been issued in whole or in part as
Bearer Securities, in London or in such place outside the United States as the
Trustee shall determine. Notice of every meeting of Holders of Securities of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided in Section 1.6, not less than 21 nor more than 180 days prior to
the date fixed for the meeting.

               (2) In case at any time the Company (by or pursuant to a Board
Resolution) or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 15.1, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed
notice of or made the first publication of the notice of such meeting within 21
days after receipt of such request (whichever shall be required pursuant to
Section 1.6) or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount above specified, as the case may be, may determine the time and the
place in the Borough of Manhattan, The City of New York, or, if Securities of
such series are to be issued as Bearer Securities, in London for such meeting
and may call such meeting for such purposes by giving notice thereof as provided
in clause (1) of this Section.

convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any reconvened meeting, such

<PAGE>

expressly the percentage, as provided above, of the principal amount of the
Outstanding Securities of such series which shall constitute a quorum.

        Except as limited by the proviso to Section 9.2, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any

series.

        Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

SECTION 15.5.  DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
               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 of Securities shall be proved in the manner specified in Section 1.4
and the appointment of any proxy shall be proved in the manner specified in
Section 1.4 or by having the signature of the person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 1.4 to certify to the holding of Bearer Securities. Such regulations may
provide that 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(2), 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.


                                      -73-
<PAGE>

               (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 held as so adjourned without further notice.

SECTION 15.6.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of 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 in triplicate of all votes cast at the meeting. A record, at least in
triplicate, 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

of the matters therein stated.

                           SUBORDINATION OF SECURITIES

SECTION 16.1.  SECURITIES SUBORDINATE TO SENIOR INDEBTEDNESS.

        The Company covenants and agrees, and each Holder of a Security, by his
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the Indebtedness represented
by the Securities and the payment of the principal of (and premium, if any) and
interest on each and all of the Securities are hereby expressly made subordinate
and subject in right of payment to the prior payment in full of all Senior
Indebtedness.

        Notwithstanding the foregoing, if a deposit referred to in Section
4.2(4)(a) is made pursuant to Section 4.2(2) or Section 4.2(3) with respect to
any Securities (and provided all other conditions set out in Section 4.2(4)
shall have been satisfied with respect to such Securities), then, following such
deposit or following the 123rd day after such deposit with respect to defeasance
only, no money or Government Obligations so deposited, and no proceeds thereon,
will be subject to any rights of holders of Senior Indebtedness, including any
such rights arising under this Article 16.

SECTION 16.2.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

        In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its creditors,
as such, or to its assets, or (b) any liquidation, dissolution or other winding
up of the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshalling of assets and liabilities of the Company, then and in any
such event the holders of Senior Indebtedness shall be entitled to receive
payment in full of all amounts due or to become due on or in respect of all
Senior Indebtedness, or provision shall be made for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, before the Holders of the Securities are entitled to receive any
payment or distribution of any kind or character, whether in cash, property or
securities (including any payment or distribution which may be payable or
deliverable by reason of the payment of any other Indebtedness of the Company
subordinated to the payment of the Securities), on account of principal of (or
premium, if any) or interest on the Securities or on account of any purchase or
other acquisition of Securities by the Company or any Subsidiary of the Company
(all such payments, distributions, purchases and acquisitions herein referred
to, individually and collectively, as a "Securities Payment"), and to that end
the holders of Senior Indebtedness shall be entitled to receive, for application
to the payment thereof, any Securities Payment.

        In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
Securities Payment, before all Senior Indebtedness is paid in full or payment
thereof provided for in cash or cash equivalents or otherwise in a manner
satisfactory to holders of Senior Indebtedness, and if such fact shall, at or
prior to the time of such Securities Payment, have been made known to the
Trustee or, as the case may be, such Holder, then and in such event such
Securities Payment shall be paid over or delivered forthwith to the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other
Person making payment or distribution of assets of the Company for application
to the payment of all Senior Indebtedness remaining unpaid, to the extent
necessary to pay all Senior Indebtedness in full, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.
Any taxes that have been withheld or deducted from any Securities Payment, or
any taxes that ought to have been withheld or deducted from any such Securities
Payment that have been remitted to the relevant taxing authority, shall not be
considered to be an amount that the Trustee or the Holder of any Security
receives for purposes of this Section.

        For purposes of this Article only, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment which are subordinated
in right of payment to all Senior Indebtedness which may at the time be
outstanding to substantially the same extent as, or to a greater extent than,
the Securities are so subordinated as provided in this Article. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the conveyance
or transfer of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article 8 shall not be deemed
a dissolution, winding up, liquidation, reorganization, assignment for the
benefit of creditors or marshalling of assets and liabilities of the Company for
the purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or which acquires by conveyance or transfer such
properties and assets substantially as an entirety, as the case


                                      -75-
<PAGE>

may be, shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions set forth in Article 8.

SECTION 16.3.  NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.

        Anything in this Indenture to the contrary notwithstanding, no
Securities Payment shall be made by or on behalf of the Company (i) unless full
payment of amounts then due for principal and interest and of all other
obligations then due on all Senior Indebtedness has been made or duly provided
for pursuant to the terms of the instrument governing such Senior Indebtedness,
(ii) if, at the time of such payment, redemption, purchase or other acquisition,
or immediately after giving effect thereto, there shall exist under any Senior
Indebtedness, or any agreement pursuant to which any Senior Indebtedness is
issued, any default, which default shall not have been cured or waived and which
default shall have resulted in the full amount of such Senior Indebtedness being
declared due and payable or (iii) if, at the time of such payment, redemption,
purchase or other acquisition, the Trustee shall have received written notice
from the holder or holders of any Senior Indebtedness or their representative or
representatives (a "Payment Blockage Notice") that there exists under such
Senior Indebtedness, or any agreement pursuant to which such Senior Indebtedness
is issued, any default, which default shall not have been cured or waived,
permitting the holders thereof to declare the full amount of such Senior
Indebtedness due and payable, but only for the period (the "Payment Blockage
Period") commencing on the date of receipt of the Payment Blockage Notice and
ending (unless earlier terminated by notice given to the Trustee by the Holders
of such Senior Indebtedness) on the earlier of (A) the date on which such event
of default shall have been cured or waived or shall have ceased to exist or the
Senior Indebtedness to which such default relates shall have been discharged or
(B) 180 days from the receipt of the Payment Blockage Notice; provided, however,
that nothing in this Section shall prevent the satisfaction of any sinking fund
payment in accordance with Article 12 hereof by delivery and crediting pursuant
to Section 12.2 Securities which have been acquired (upon redemption or
otherwise) prior to the acceleration of any such default listed in (i) or (ii)
directly above or prior to receipt of any Payment Blockage Notice. Upon
termination of a Payment Blockage Period, payments on account of principal of,
premium, if any, or interest on the Securities, and redemptions, purchases or
other acquisitions may be made by or on behalf of the Company. Notwithstanding
anything herein to the contrary, (A) only one Payment Blockage Notice may be
given during any period of 360 consecutive days with respect to the same event
of default and any other events of default on the same issue of Senior
Indebtedness existing and known to the person giving such notice at the time of
such notice and (B) no new Payment Blockage Period may be commenced by the
holder or holders of the same issue of Senior Indebtedness or their
representative or representatives during any period of 360 consecutive days
unless all events of default which were the object of the immediately preceding
Payment Blockage Notice, and any other event of default on the same issue of
Senior Indebtedness existing and known to the person giving such notice at the
time of such notice, have been cured or waived for a period of at least 90
consecutive days.

        In the event that, notwithstanding the provisions of this Section 16.3,
payments are made by or on behalf of the Company in contravention of the
provisions of this Section 16.3, such payments shall be held by the Trustee, any
Paying Agent or the Holders, as applicable, in trust for the benefit of, and
shall be paid over to and delivered to, the holders of Senior Indebtedness or
their representative or the trustee under the indenture or other agreement (if
any), pursuant to which any instruments evidencing any Senior Indebtedness may
have been issued, as their respective interests may appear, for application to
the payment of all Senior Indebtedness remaining unpaid to the extent necessary
to pay all Senior Indebtedness in full in accordance with the terms of such
Senior Indebtedness, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.


                                      -76-
<PAGE>

        The provisions of this Section shall not apply to any payment with
respect to which Section 16.2 would be applicable.

SECTION 16.4   RELIANCE BY SENIOR INDEBTEDNESS ON SUBORDINATION PROVISIONS.

        Each Holder of any Security by his acceptance thereof acknowledges and
agrees that the foregoing subordination provisions are, and are intended to be,
an inducement and a consideration for each holder of any Senior Indebtedness,
whether such Senior Indebtedness was created or acquired before or after the
issuance of the Securities, to acquire and continue to hold, or to continue to
hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in acquiring
and continuing to hold or in continuing to hold such Senior Indebtedness.

SECTION 16.5.  PAYMENT PERMITTED IF NO DEFAULT.

        Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 16.2 or under the conditions
described in Section 16.3, from making Securities Payments, or (b) the
application by the Trustee of any money deposited with it hereunder to
Securities Payments or the retention of such Securities Payments by the Holders,
if, at the time of such application by the Trustee, it did not have knowledge
that such Securities Payments would have been prohibited by the provisions of
this Article.

SECTION 16.6.  SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

        Subject to the payment in full of all Senior Indebtedness or the
provision for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Indebtedness, the Holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Indebtedness pursuant to the provisions of
this Article (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to indebtedness of the
Company to substantially the same extent as the Securities are subordinated and
is entitled to like rights of subrogation) to the rights of the holders of such
Senior Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of (and
premium, if any) and interest on the Securities shall be paid in full. For
purposes of such subrogation, no payments or distributions to the holders of the
Senior Indebtedness of any cash, property or securities to which the Holders of
the Securities or the Trustee would be entitled except for the provisions of
this Article, and no payments over pursuant to the provisions of this Article to
the holders of Senior Indebtedness by Holders of the Securities or the Trustee,
shall, as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.


                                      -77-
<PAGE>

SECTION 16.7.  PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

        The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the obligation
of the Company, which is absolute and unconditional (and which, subject to the
rights under this Article of the holders of Senior Indebtedness, is intended to
rank equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of (and premium, if any) and interest on
the Securities as and when the same shall become due and payable in accordance
with their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article of the
holders of Senior Indebtedness to receive cash, property and securities
otherwise payable or deliverable to the Trustee or such Holder.

SECTION 16.8.  TRUSTEE TO EFFECTUATE SUBORDINATION.

        Each holder of a Security by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.

SECTION 16.9.  NO WAIVER OF SUBORDINATION PROVISIONS.

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

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


                                      -78-

SECTION 16.10. NOTICE TO TRUSTEE.

        The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee therefor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 6.1, shall be entitled in all respects to assume that no
such facts exist.

        Subject to the provisions of Section 6.1, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee therefor) to
establish that such notice has been given by a holder of Senior Indebtedness (or
a trustee therefor). In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness to participate in any payment or distribution pursuant to
this Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

SECTION 16.11. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

        Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 6.1, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article.

SECTION 16.12. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS.

        The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Indebtedness and shall not be liable to any such holders if it shall
in good faith mistakenly pay over or distribute to Holders of Securities or to
the Company or to any other Person cash, property or securities to which any
holders of Senior Indebtedness shall be entitled by virtue of this Article or
otherwise.


                                      -79-
<PAGE>

SECTION 16.13. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS; PRESERVATION
               OF TRUSTEE'S RIGHTS.

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

        Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.7.

SECTION 16.14. ARTICLE APPLICABLE TO PAYING AGENTS.

        In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided,
however, that Section 16.13 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

SECTION 16.15. DEFEASANCE OF THIS ARTICLE 16.

        The subordination of the Securities provided by this Article 16 is
expressly made subject to the provisions for defeasance in Section 4.2(2) hereof
or covenant defeasance in Section 4.2(3) hereof and, anything herein to the
contrary notwithstanding, upon the effectiveness of any such defeasance or
covenant defeasance, the Securities then outstanding shall thereupon cease to be
subordinated pursuant to this Article 16.

                           [Intentionally left blank]
