a meeting of Holders of Securities for quorum purposes, (i) the principal amount
of an Original Issue Discount Security that may be counted in making such

other obligor, shall be disregarded and deemed not to be Outstanding, except

determination or relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Securities which a Responsible
Officer of the Trustee actually knows to be so owned shall be so disregarded.
Securities so owned which shall have been pledged in good faith may be regarded
as Outstanding if the pledgee establishes to the satisfaction of the Trustee (A)
the pledgee's right so to act with respect to such Securities and (B) that the

      to be given or taken by Holders may be embodied in and evidenced by one or
      more instruments of substantially similar tenor signed by such Holders in
      person or by an agent duly appointed in writing. If, but only if,
      Securities of a series are issuable as Bearer Securities, any request,
      demand, authorization, direction, notice, consent, waiver or other action
      provided in or pursuant to this Indenture to be given or taken by Holders
      of Securities of such series may, alternatively, be embodied in and
      evidenced by the record of Holders of Securities of such series voting in
      favor thereof, either in person or by proxies duly appointed in writing,
      at any meeting of Holders of Securities of such series duly called and
      held in accordance with the provisions of Article 15, or a combination of
      such instruments and any such record. Except as herein otherwise expressly
      provided, such action shall become effective when such instrument or
      instruments or record or both are delivered to the Trustee and, where it
      is hereby expressly required, to the Company or the Guarantors or both of
      them. Such instrument or instruments and any such record (and the action
      embodied therein and evidenced thereby) are herein sometimes referred to
      as the "Act" of the Holders signing such instrument or instruments or so
      voting at any such meeting. Proof of execution of any such instrument or
      of a writing appointing any such agent, or of the holding by any Person of
      a Security, shall be sufficient for any purpose of this Indenture and
      (subject to Section 315 of the Trust Indenture Act) conclusive in favor of
      the Trustee, the Company, the Guarantors and any agent of the Trustee, the
      Company or the Guarantors, if made in the manner provided in this Section.

      manner provided in Section 15.6.

            Without limiting the generality of this Section 1.4, unless
      otherwise provided in or pursuant to this Indenture, a Holder, including a

      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, and a U.S. Depository that is a Holder of a global Security may
      provide its proxy or proxies to

                                       14
<PAGE>

      the beneficial owners of interests in any such global Security through
      such U.S. Depository's standing instructions and customary practices.

            The Company shall fix a record date for the purpose of determining
      the Persons who are beneficial owners of interests 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 and the Guarantors, wherever
      situated, if such certificate shall be deemed by the Company, the
      Guarantors 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, the Company and the Guarantors
      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, the Guarantors and the Trustee deem
      sufficient.

            (5)   If the Company or the Guarantors shall solicit from the
      Holders of any Registered Securities any request, demand, authorization,
      direction, notice, consent,

                                       15
<PAGE>

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

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

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

      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, any Guarantor 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 or any Guarantor, as the case may be, 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 or the Guarantors, as the case
      may be, addressed to the attention of its Treasurer, with a copy to the
      attention of its General Counsel, at the address of its principal office
      specified in the first paragraph of this instrument or at any other
      address previously furnished in writing to the Trustee by the Company or
      the Guarantors, as the case may be.

      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,

                                       16
<PAGE>

            (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 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 or the Guarantors, as the case may be, so
elect, any published notice may be in an official language of the country of
publication.

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

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) their
obligations under this Indenture to make payments in the Required Currency (i)
shall not be discharged or satisfied by any tender, or any recovery pursuant to
any judgment (whether or not entered in accordance with clause (a)), in any
currency other than the Required Currency, except to the extent that such tender
or recovery shall result in the actual receipt, by the payee, of the full amount
of the Required Currency expressed to be payable in respect of such payments,
(ii) shall be enforceable as an alternative or additional cause of action for
the purpose of recovering in the Required Currency the amount, if any, by which
such actual receipt shall fall short of the full amount of the Required Currency
so expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the

      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 and the Guarantors, 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 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, including the
            Guarantee; provided, however, that such Opinion of Counsel need
            express no opinion as to the availability of equitable remedies;

                  (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

                                       27
<PAGE>

                  (2)   an Officer's Certificate and a Guarantors' Officer's
            Certificate, in each case 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 and Guarantors' Officer's Certificate at the time of issuance of
each Security, but such opinion and certificates, 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 and the Guarantors 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 6.11 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 3.6 or 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 appropriate insertions, omissions, substitutions and other variations as

                                       28
<PAGE>

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.

                                       29
<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,
the Guarantors 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, the Guarantors 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 shall not be payable on such Interest Payment
Date or proposed date for payment 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

                                       30
<PAGE>

authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

      Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, 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 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

                                       31
<PAGE>

Defaulted Interest, as the case may be, interest shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of such Registered Security, but shall be payable on such Interest
Payment Date or proposed date for payment, as the case may be, only to the
Person to whom interest in respect of such portion of such global Security shall
be payable in accordance with the provisions of this Indenture.

      All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company and each Guarantor,
respectively, 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.

                                       32
<PAGE>

      If there is delivered to the Company, any Guarantor 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, any Guarantor 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 destroyed, lost or stolen Security or in
exchange for the Security to which a destroyed, lost or stolen Coupon appertains
with all appurtenant Coupons not destroyed, lost or stolen, a new Security of
the same series containing identical terms and of like principal amount and
bearing a number not contemporaneously outstanding, with Coupons appertaining
thereto corresponding to the Coupons, if any, appertaining to such destroyed,
lost or stolen Security or to the Security to which such destroyed, lost or
stolen Coupon appertains.

      Notwithstanding the foregoing provisions of this Section 3.6, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 10.2, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
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 and the Guarantors,
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 that shall
be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in

                                       33
<PAGE>

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 that 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 or any Guarantor, at its election
in each case, as provided in clause (1) or (2) below:

            (1)   The Company or any Guarantor, as the case may be, 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 or any Guarantor, as the case may be,
      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 or any Guarantor, as the case may be, 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 in this
      clause provided. The Special Record Date for the payment of such Defaulted
      Interest shall be not more than 15 days and not less than 10 days prior to
      the date of the proposed payment and not less than 10 days after
      notification to the Trustee of the proposed payment. The Trustee shall, in
      the name and at the expense of the Company or the Guarantors, 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 or any Guarantor, 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 or any Guarantor, as the case may be, 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

                                       34
<PAGE>

      or any Guarantor, as the case may be, to the Trustee of the proposed
      payment pursuant to this clause, such payment shall be deemed practicable
      by the Trustee.

      Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company or any Guarantor, 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 the
Guarantors or 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 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 Guarantors, the Trustee and any agent of the Company
or the Guarantors or the Trustee may treat the Person in whose name such

another issuer shall survive.

      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

      thereto as may be specified pursuant to Section 3.1 with respect to any
      Securities), shall be applicable to such Securities and any Coupons

      the Company and each Guarantor shall be deemed to have been discharged
      from its obligations with respect to such Outstanding Securities and any
      Coupons appertaining thereto and under the Guarantee in respect thereof,
      respectively, 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 and/or the Guarantors shall be
      deemed to have paid and discharged the entire Indebtedness represented by
      such Outstanding Securities and any Coupons appertaining thereto, and
      under the Guarantee in respect thereof, 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 under the
      Guarantee in respect thereof, and this Indenture insofar as such
      Securities and any Coupons appertaining thereto, and the Guarantee in
      respect thereof, are concerned (and the Trustee, at the expense of the
      Company and the Guarantors, 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 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 a Guarantor or
      another issuer,

                                       38
<PAGE>

      (ii) the obligations of the Company, the Guarantors 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 Sections 10.4 and 16.1 (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 the Guarantors or 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 and the Guarantors shall be released from their 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, with respect to
      such Outstanding Securities and any Coupons appertaining thereto, and the
      Guarantees in respect thereof, 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
      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 and the Guarantors 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, whether directly or
      indirectly, by reason of any reference elsewhere herein to any such
      Section or such other covenant or by reason of reference in any such
      Section or such other covenant 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(9) or otherwise, as the
      case may be, but, except as specified above, the remainder of this
      Indenture and such Securities and Coupons appertaining thereto and the
      Guarantee in respect thereof 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 and the Guarantee in respect
      thereof:

                  (a)   The Company or any Guarantor shall irrevocably have
            deposited or caused to be deposited with the Trustee (or another
            trustee satisfying the requirements of Section 6.7 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 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 or the Guarantors is a party or by which either of them 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

                                       40

            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 or the
            Guarantors under any federal or State bankruptcy, insolvency,
            reorganization or other similar law, or any decree or order for
            relief in respect of the Company or the Guarantors issued in
            connection therewith.

                  (g)   The Company and the Guarantors shall have delivered to
            the Trustee an Officer's Certificate and a Guarantors' Officer's
            Certificate and the Company shall have delivered to the Trustee an
            Opinion of Counsel 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.

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

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

      Section 4.3. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 10.3, all money
and Government Obligations (or other property as may be provided pursuant to
Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or 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 or the Guarantors acting as 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

      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 (7) or (8)
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 (7) or (8) 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 or the Guarantors have paid or deposited with the
      Trustee a sum of money sufficient to pay

                  (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 6.6; 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.

                                       45
<PAGE>

      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 and each Guarantor covenants, in each case, 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 or the Guarantors, as the case may be, 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 6.6.

      If the Company or any Guarantor 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 against the Company or the Guarantor or any other obligor upon
such Securities and any Coupons appertaining thereto and collect the monies
adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or the Guarantor or any other obligor upon such
Securities and any Coupons appertaining thereto, wherever situated.

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

      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

                                       46
<PAGE>

Company, the Guarantors or any other obligor upon the Securities of any series
or the property of the Company, the Guarantors 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 or the Guarantors 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 6.6.

      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.

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:

      predecessor Trustee under Section 6.6;

            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; and

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

      Section 5.7. Limitations on Suits.

thereto shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, or to
obtain or to seek to obtain priority or preference over any other Holders or to

                                       48
<PAGE>

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 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

      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 Guarantors, 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.

      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

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

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 and
the Guarantors expressly waive (to the extent that they may lawfully do so) all
benefit or advantage of any such law and covenant 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.

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

exchange any Security into other securities in accordance with its terms.

      Section 6.6. Compensation and Reimbursement.

<PAGE>

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

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

            (3)   to indemnify the Trustee and its agents, officers, directors
      and employees for, and to hold them harmless against, any loss, liability
      or expense incurred without negligence or bad faith on their part, arising
      out of or in connection with the acceptance or administration of the trust
      or trusts hereunder, including the costs and expenses of defending
      themselves against any claim or liability in connection with the exercise
      or performance of any of their powers or duties hereunder, except to the
      extent that any such loss, liability or expense was due to the Trustee's
      negligence or bad faith.

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

      To the extent permitted by law, any compensation or expense incurred by
the Trustee after a default specified in or pursuant to Section 5.1 is intended
to constitute an expense of administration under any then applicable bankruptcy
or insolvency law. "Trustee" for purposes of this Section 6.6 shall include any
predecessor Trustee but the negligence or bad faith of any Trustee shall not
affect the rights of any other Trustee under this Section 6.6.

      The provisions of this Section 6.6 shall survive the satisfaction and
discharge of this Indenture or the earlier resignation or removal of the Trustee
and shall apply with equal force and effect to the Trustee in its capacity as
Authenticating Agent, Paying Agent or Security Registrar.

      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,

      shall be only one Trustee with respect to the Securities of any particular
      series) and shall comply with the applicable requirements of Section 6.9.
      If, within one year 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, the Guarantors and the retiring Trustee, the

      6.9, become the successor Trustee with respect to the Securities of such
      series and to that extent supersede the successor Trustee appointed by the
      Company and the Guarantors. If no successor Trustee with respect to the
      Securities of any series shall have been so appointed by the Company and
      the Guarantors or the Holders of Securities and accepted appointment in
      the manner required by Section 6.9, any Holder of a Security who has been

      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

      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, the

      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 6.6.

      respect to the Securities of one or more (but not all) series, the
      Company, the Guarantors, the retiring Trustee and such successor Trustee
      shall execute and deliver an indenture supplemental hereto wherein each
      successor Trustee shall accept such appointment and which (1) shall
      contain such provisions as shall be necessary or desirable to transfer and
      confirm to, and to vest in, such successor Trustee all the rights, powers,
      trusts and duties of the retiring Trustee with respect to the Securities

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

      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, the Guarantors
      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 6.6.

            (3)   Upon request of any Person appointed hereunder as a successor
      Trustee, the Company and the Guarantors 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 6.10. Merger, Conversion, Consolidation or Succession to Business.

      Any Corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party or any
Corporation succeeding to all or substantially all of the corporate agency or
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

      Section 6.11. Appointment of Authenticating Agent.

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

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

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

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

                                       58
<PAGE>

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 and each Guarantor (without duplication) agree 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 6.6.

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

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

convertible or exchangeable may be surrendered for conversion or exchange, and
where notices and demands to or upon the Company or the Guarantors in respect of
the Securities of such series relating thereto and this Indenture may be served.
If Securities of a series are issuable as Bearer Securities, the Company and the
Guarantors 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 and the Guarantors shall
maintain a Paying Agent in London, Luxembourg or any other required city located
outside the United States so long as the Securities of such series are listed on
such exchange. The Company and the Guarantors 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 or the Guarantors 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
and the Guarantors hereby appoint the Trustee as their 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 and the Guarantors
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
and the Guarantors in accordance with this Indenture is illegal or effectively
precluded by exchange controls or other similar restrictions.

      The Company and the Guarantors 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 or the Guarantors of its
obligation to maintain an Office or Agency in each Place of

                                       68
<PAGE>

Payment for Securities of any series for such purposes. The Company and the
Guarantors 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 and the Guarantors hereby designate as the Place of Payment for each
series of Securities the Borough of Manhattan, The City of New York, and
initially appoint 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 and the Guarantors may subsequently appoint a different
Office or Agency in the Borough of Manhattan, The City of New York for the
Securities of any series.

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

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

      If the Company shall at any time act as its own Paying Agent, or if the
Guarantors shall act as 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;

                                       69
<PAGE>

            (2)   give the Trustee notice of any default by the Company or the
      Guarantors (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 or the Guarantors 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 or Guarantor's Order direct any Paying Agent
to pay, to the Trustee all sums held in trust by the Company, the Guarantors 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, the Guarantors or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
sums.

      Except as otherwise provided herein or pursuant hereto, any money
deposited with the Trustee or any Paying Agent, or then held by the Company or
the Guarantors, 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 deposited by the Guarantors, paid to the Guarantors on
Guarantor's Request), or (if then held by the Company or the Guarantors) 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 and the Guarantors 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 and the Guarantors 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 or the Guarantors, as the case may be.

      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

                                       70
<PAGE>

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
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 Liens.

      The Company covenants and agrees for the benefit of each series of
Securities, other than any series established in or pursuant to a Board
Resolution or in one or more indentures supplemental hereto which specifically
provides otherwise, that the Company will not, nor will it permit any Restricted
Subsidiary to, at any time create, incur, assume or guarantee any Debt secured
by any mortgage, pledge, lien, security interest or other encumbrance ("Lien")
on any property (including shares of Capital Stock or Debt) of the Company or of
any Restricted Subsidiary, whether now owned or hereafter acquired, without in
any such case effectively providing, concurrently with the creation, incurrence,
assumption or guarantee of such Debt, that the Securities of the applicable
series then Outstanding shall, so long as any such other Debt shall be so
secured (and, if the Company shall so determine, any other existing Debt (or
Debt thereafter in existence) created, incurred, assumed or guaranteed by the
Company or any Restricted Subsidiary), be secured by any such Lien equally and
ratably with or prior to any and all other Debt thereby secured, provided,
however, that the foregoing covenant shall not be applicable to the following:

            (a)   All Liens on property of the Company or any Restricted
      Subsidiary existing on the date of original issuance by the Company of the
      applicable series of Securities issued pursuant to this Indenture or such
      other date as may be specified in or

                                       71
<PAGE>

      pursuant to a Board Resolution and set forth in an Officer's Certificate,
      or in one or more indentures supplemental hereto pursuant to which such
      series is established; or

            (b)   Liens on property acquired by the Company or any Restricted
      Subsidiary (including acquisition through merger or consolidation);
      provided that such Liens were in existence prior to and were not created
      in contemplation of such acquisition and shall not extend to any other
      property of the Company or any Restricted Subsidiary; or

            (c)   Liens on any property (including, in the case of a plant or
      facility, the land on which it is erected and fixtures comprising a part
      thereof) of the Company or any Restricted Subsidiary securing the payment
      of all or any part of the purchase price or construction cost thereof or
      securing any Debt created, incurred, assumed or guaranteed prior to, at
      the time of or within 120 days after the latest of the acquisition of such
      property or the completion of such construction, for the purpose of
      financing all or any part of the purchase price or construction cost
      thereof (provided, in the case of Liens securing the payment of all or any
      part of the purchase price of any property of the Company or any
      Restricted Subsidiary, as the case may be, or securing any Debt created,
      incurred, assumed or guaranteed for the purposes of financing all or any
      part of such purchase price, such Liens are limited to the property then
      being acquired and fixed improvements thereon and the Capital Stock of any
      Person formed to acquire such property and provided further in the case of
      Liens securing the payment of all or any part of the construction cost of
      any property of the Company or any Restricted Subsidiary, as the case may
      be, or securing any Debt created, incurred, assumed or guaranteed for the
      purpose of financing all or any part of such construction cost, such Liens
      are limited to the assets or property then being constructed and the land
      on which such property is erected and fixtures comprising a part thereof);
      or

            (d)   Liens on any property to secure all or any part of the cost of
      development, construction, alteration, repair or improvement of all or any
      part of such property, or to secure Debt created, incurred, assumed or
      guaranteed prior to, at the time of or within 120 days after the latest of
      the completion of such development, construction, alteration, repair or
      improvement, for the purpose of financing all or any part of such cost
      (provided such Liens do not extend to or cover any property of the Company
      or any Restricted Subsidiary other than the property then being developed,
      constructed, altered, repaired or improved and the land on which such
      property is erected and fixtures comprising a part thereof); or

            (e)   Liens in favor of the Company or a Restricted Subsidiary
      securing Debt of the Company or a Restricted Subsidiary; or

            (f)   Liens created in connection with tax assessments or legal
      proceedings and mechanics' liens and materialmen's liens and other similar
      liens created in the ordinary course of business; or

            (g)   Liens on property of the Company or any Restricted Subsidiary
      (except property consisting of the Capital Stock or Debt of the Company or
      any Restricted Subsidiary) in favor of the United States of America or any
      State thereof, or any

                                       72
<PAGE>

      department, agency or instrumentality or political subdivision of the
      United States of America or any State thereof, or in favor of any other
      country, or any department, agency or instrumentality or political
      subdivision thereof, to secure partial, progress, advance or other
      payments pursuant to any contract or statute or to secure any Debt
      created, incurred, assumed or guaranteed for the purpose of financing all
      or any part of the purchase price or the cost of construction or
      improvement of the property subject to such Liens (including, but not
      limited to, Liens created in connection with pollution control, industrial
      revenue bond or similar financings); or

            (h)   Any extension, renewal or replacement (or successive
      extensions, renewals or replacements), in whole or in part, of any Lien
      referred to in the foregoing subparagraphs (a) through (g); provided that
      any of the foregoing are limited to the same property subject to, and
      securing no more Debt than the Lien so extended, renewed or replaced.

      Notwithstanding the foregoing provisions of this Section 10.5, the Company
and any Restricted Subsidiary may create, incur, assume or guarantee Debt of the
Company or any Restricted Subsidiary which would otherwise be subject to the
foregoing restrictions, without equally and ratably securing the applicable
series of Securities, if the aggregate principal amount of all Debt secured by
Liens on property (including shares of Capital Stock or Debt) of the Company and
of any Subsidiary then outstanding (not including Debt permitted to be secured
under subparagraphs (a) through (h) above), plus Attributable Debt of the
Company and its Subsidiaries in respect of Sale/Leaseback Transactions that
would otherwise be subject to the restrictions set forth in Section 10.6, does
not at the time such Debt is created, incurred, assumed or guaranteed exceed 10%
of Consolidated Net Tangible Assets.

      If a secured revolving credit facility is established or increased without
equally and ratably securing outstanding Securities in compliance with the
immediately preceding paragraph, then all subsequent borrowings under such
revolving credit facility shall be deemed to be permissible under this Section
10.5.

      For the purposes of this Section 10.5, the creation of a Lien on property
(including shares of Capital Stock or Debt) of the Company or of any Restricted
Subsidiary to secure Debt which existed prior to the creation of such Lien shall
be deemed to involve the creation of Debt secured by a Lien in an amount equal
to the principal amount secured by such Lien.

      Section 10.6. Limitation on Sale/Leaseback Transactions.

      The Company covenants and agrees for the benefit of each series of
Securities, other than any series established in or pursuant to a Board
Resolution or in one or more indentures supplemental hereto which specifically
provides otherwise, that neither the Company nor any Restricted Subsidiary will
enter into any Sale/Leaseback Transaction after the date of the original
issuance by the Company of the applicable series of Securities issued pursuant
to this Indenture, or such other date as may be specified in or pursuant to a
Board Resolution and set forth in an Officer's Certificate, or in one or more
indentures supplemental hereto pursuant to which such series is established,
with any Person (other than the Company or a Restricted Subsidiary) providing
for a term of more than three years unless:

                                       73
<PAGE>

            (a)   the Company or such Restricted Subsidiary would be permitted,
      pursuant to the terms of Section 10.5, to incur Debt in a principal amount
      equal to or exceeding the Attributable Debt in respect of such
      Sale/Leaseback Transaction secured by a Lien on the property subject to
      such Sale/Leaseback Transaction without equally and ratably securing the
      applicable series of Securities; or

            (b)   since the date of this Indenture and within a period
      commencing six months prior to the consummation of the Sale/Leaseback
      Transaction and ending six months after the consummation thereof, the
      Company or such Restricted Subsidiary has expended or will expend for any
      property (including amounts expended for the acquisition thereof, or for
      additions, alterations, improvements or repairs thereto) an amount up to
      the net proceeds of such Sale/Leaseback Transaction, and the Company
      elects to designate such amount as a credit against such Sale/Leaseback
      Transaction (with any amount of such net proceeds not being so designated
      to be applied as set forth in paragraph (c) below); or

            (c)   the Company, during or immediately after the expiration of the
      12-month period following the consummation of the Sale/Leaseback
      Transaction, applies or causes such Restricted Subsidiary to apply to the
      voluntary retirement, redemption or defeasance of Securities of any series
      or other Funded Debt of the Company (other than Funded Debt subordinated
      to the Securities) or Funded Debt of such Restricted Subsidiary an amount
      equal to the greater of (i) the net proceeds of the Sale/Leaseback
      Transaction and (ii) the fair value, in the opinion of the Board of
      Directors of the Company, of the subject property of the Sale/Leaseback
      Transaction at the time of such transaction (adjusted, in either case, to
      reflect the remaining term of the lease and any amount applied pursuant to
      paragraph (b) above), less an amount equal to the principal amount of any
      such Funded Debt of the Company or such Restricted Subsidiary, other than
      Securities, voluntarily retired by the Company or such Restricted
      Subsidiary during such 12-month period.

      "Sale/Leaseback Transaction" means any arrangement providing for the
leasing to the Company or any Restricted Subsidiary by any Person (other than
the Company or a Restricted Subsidiary) of any property which has been, or is to
be, sold or transferred by the Company or such Restricted Subsidiary to such
Person or to any Person (other than the Company or a Restricted Subsidiary) to
which funds have been or are to be advanced by such Person on the security of
the leased property.

      Section 10.7. Issuance of Subsidiary Guarantees.

      The Company shall not cause or permit any of its Restricted Subsidiaries,
directly or indirectly, to guarantee any Debt of the Company unless such
Restricted Subsidiary:

            (1)   executes and delivers to the Trustee a supplemental indenture
      in form reasonably satisfactory to the Trustee pursuant to which such
      Restricted Subsidiary shall unconditionally Guarantee all of the Company's
      obligations under the Securities and this Indenture on the terms set forth
      in this Indenture; and

                                       74
<PAGE>

            (2)   delivers to the Trustee an Opinion of Counsel (which may
      contain customary exceptions) that such supplemental indenture has been
      duly authorized, executed and delivered by such Restricted Subsidiary and
      constitutes a legal, valid, binding and enforceable obligation of such
      Restricted Subsidiary.

      Thereafter, such Restricted Subsidiary shall be a Guarantor for all
purposes of this Indenture until such Guarantee is released in accordance with
the provisions of Article 16. The Company may cause any other Restricted
Subsidiary to issue a Guarantee and become a Guarantor.

      Section 10.8. Corporate Existence.

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

      Section 10.9. Waiver of Certain Covenants.

      The Company or the Guarantors, as the case may be, 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 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 Guarantors and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

      Section 10.10. Company Statement as to Compliance; Notice of Certain
Defaults.

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

                  (a)   a review of the activities of the Company and its
            Subsidiaries 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, (i) the Company and each Guarantor have 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

                                       75
<PAGE>

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

            (2)   The Company and each Guarantor 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 10.10.

                                   ARTICLE 11

                            REDEMPTION OF SECURITIES

      Section 11.1. Applicability of Article.

      Redemption of Securities of any series at the option of the Company as

accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

      Section 11.2. Election to Redeem; Notice to Trustee.

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

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

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

                                       76
<PAGE>

      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 before termination of the
conversion right with respect to the portion of the Security so selected, the
converted portion of such Security shall be deemed (so far as may be) to be the
portion selected for redemption. Securities which have been converted or
exchanged during a selection of Securities to be redeemed shall be treated by
the Trustee as Outstanding for the purpose of such selection.

      Section 11.4. Notice of Redemption.

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

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

      All notices of redemption shall state:

            (1)   the Redemption Date,

            (2)   the Redemption Price,

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

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

                                       77
<PAGE>

            (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 Guarantors, 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 or the Guarantors 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 or the Guarantors are acting as 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

                                       78
<PAGE>

(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 and the Guarantors 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.

                                   ARTICLE 12

                                  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 or the Guarantors 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

                                       80
<PAGE>

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 or Guarantors' 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 or the Guarantors from time to time pay over
and deliver to the Company or the Guarantors, as the case may be, any cash
payment so being held by the Trustee or such Paying Agent upon delivery by the
Company or the Guarantors to the Trustee of Securities of that series purchased
by the Company or the Guarantors 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.

                                   ARTICLE 13

                       REPAYMENT AT THE OPTION OF HOLDERS

      Section 13.1. Applicability of Article.

      Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a 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

                                       81
<PAGE>

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.

                                   ARTICLE 14

                        SECURITIES IN FOREIGN CURRENCIES

      Section 14.1. Applicability of Article.

      Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the 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 or the Guarantors 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
of such series.

      Section 15.2. Call, Notice and Place of Meetings.

            (1)   The Trustee may at any time call a meeting of Holders of
      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), the Guarantors (by or pursuant to a Guarantors' 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, the Guarantors or the Holders of Securities of such
      series in the amount above specified 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.

      Section 15.3. Persons Entitled to Vote at Meetings.

      To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such

Trustee and its counsel, any representatives of the Guarantors and their counsel
and any representatives of the Company and its counsel.

      Section 15.4. Quorum; Action.

      The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of
Holders of Securities of such series. In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a

                                       83
<PAGE>

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 reconvened meeting may be further adjourned for a
period of not less than 10 days as determined by the chairman of the meeting
prior to the adjournment of such reconvened meeting. Notice of the reconvening
of any adjourned meeting shall be given as provided in Section 15.2(1), except
that such notice need be given only once not less than five days prior to the
date on which the meeting is scheduled to be reconvened. Notice of the
reconvening of an adjourned meeting shall state 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
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage, which is less
than a majority, in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of such
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, the Guarantors or the Holders of
      Securities of the series calling the meeting shall in like manner appoint
      a temporary chairman. A permanent chairman and a permanent secretary

                                       84
<PAGE>

      of the meeting shall be elected by vote of the Persons entitled to vote a
      majority in principal amount of the Outstanding Securities of such series
      represented at the meeting.

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

            (4)   Any meeting of Holders of Securities of any series duly called
      pursuant to Section 15.2 at which a quorum is present may be adjourned
      from time to time by Persons entitled to vote a majority in principal
      amount of the Outstanding Securities of such series represented at the
      meeting; and the meeting may be held as so adjourned without further
      notice.

      Section 15.6. Counting Votes and Recording Action of Meetings.

      The vote upon any resolution submitted to any meeting of Holders of
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 the Guarantors, and another to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

      Section 16.1. The Unconditional Guarantee.

      Each Guarantor hereby unconditionally, jointly and severally, guarantees
to each Holder of a Security authenticated by the Trustee and to the Trustee and
its successors and assigns that the principal of, premium thereon (if any) and
interest on the Securities will be promptly paid in full when due, subject to
any applicable grace period, whether at maturity, by acceleration or otherwise,

Securities and all other obligations of the Company to the Holders or the
Trustee hereunder or under the Securities will be promptly paid in full or
performed, all in accordance with the terms hereof and thereof; subject,
however, to the limitations set forth in Section 16.3 hereof. Each Guarantor
hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Securities or
this Indenture, the absence of any action to enforce the same, any waiver or
consent by any Holder with respect to any provisions hereof or thereof, the
recovery of any judgment against the Company, any action to enforce the same or
any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a Guarantor. Each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest, notice and all demands whatsoever and covenants
that the Guarantee will not be discharged except by complete performance of the
obligations contained in the Securities and this Indenture. If any Holder or the
Trustee is required by any court or otherwise to return to the Company, any
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or any Guarantor, any amount paid by the
Company or any Guarantor to the Trustee or such Holder, each Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect.
Each Guarantor further agrees that, as between a Guarantor, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the
obligations Guaranteed hereby may be accelerated as provided in Article 5 hereof
for the purpose of each Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations
as provided in Article 5 hereof, such obligations (whether or not due and
payable) shall become due and payable by each Guarantor for the purpose of each
Guarantee.

      Each Guarantor also agrees to pay any and all costs and expenses
(including reasonable attorneys' fees) incurred by the Trustee or any Holder in
enforcing any rights under this Article 16.

      Section 16.2. Severability.

      In case any provision of this Article 16 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 16.3. Limitation of Guarantors' Liability.

            (a)   To the extent applicable, a Guarantor's liability in F respect
      of its Guarantee shall be limited to the extent set forth below:

                  (1)   Limitations Applicable to U.S. Guarantors. Each
            Guarantor that is incorporated, organized or formed, as the case may
            be, under the laws of the United States, any State thereof or the
            District of Columbia (a "U.S. Guarantor"), and by its acceptance
            hereof, each Holder and the Trustee, hereby confirm that it is the
            intention of all such parties that the Guarantee of a U.S. Guarantor
            does not constitute a fraudulent transfer or conveyance for purposes
            of Title 11 of the United States Code, as amended, the Uniform
            Fraudulent Conveyance Act, the

                                       86
<PAGE>

            Uniform Fraudulent Transfer Act or any similar U.S. Federal or state
            or other applicable law. To effectuate the foregoing intention, each
            Holder and each U.S. Guarantor hereby irrevocably agree that the
            obligations of a U.S. Guarantor under its Guarantee shall be limited
            to the maximum amount as will, after giving effect to all other
            contingent and fixed liabilities of such U.S. Guarantor, result in
            the obligations of such U.S. Guarantor not constituting such a
            fraudulent transfer or conveyance.

                  (2)   Limitations Applicable to Other Guarantors. Each
            Guarantor that is incorporated, organized or formed, as the case may
            be, under the laws of any jurisdiction other than one set forth in
            clause (1) above (an "Other Guarantor"), and by its acceptance
            hereof, each Holder and the Trustee, hereby confirm that it is the
            intention of all such parties that the Guarantee of an Other
            Guarantor does not constitute a fraudulent transfer or conveyance
            for purposes of applicable law. To effectuate the foregoing
            intention, each Holder and each Other Guarantor hereby irrevocably
            agree that the obligations of an Other Guarantor under its Guarantee
            shall be limited to the maximum amount as will, after giving effect
            to all other contingent and fixed liabilities of such Other
            Guarantor, result in the obligations of such Other Guarantor not
            constituting such a fraudulent transfer or conveyance.

            (b)   If, following the date of this Indenture and notwithstanding
      anything in Section 9.2 to the contrary:

                  (1)   (i) there shall be any change in the laws of the
            jurisdiction set forth in clause (1) of subsection (a) of this
            Section 16.3 or (ii) any Restricted Subsidiary incorporated,
            organized or formed, as the case may be, under the laws of any
            jurisdiction other than one set forth in clause (1) of subsection
            (a) of this Section 16.3 (a "Future Guarantor") shall be required to
            execute a Guarantee and the Company shall reasonably determine that
            clause (2) with respect to Other Guarantors shall not adequately
            address the limitations on such Guarantee imposed by applicable law
            of the jurisdiction of incorporation, organization or formation, as
            the case may be, of any such Future Guarantor; or

                  (2)   the Company shall reasonably determine that it shall be
            necessary or advisable to amend the terms of clause (1) of
            subsection (a) of this Section 16.3 or to add additional provisions
            related to the limitations imposed on the Guarantee of a Future
            Guarantor,

      then upon the delivery of an Officers' Certificate and Opinion of Counsel
      reasonably satisfactory to the Trustee, the Company shall be entitled to
      amend such clauses or add such additional provisions (including any
      related modifications to the form of Guarantee attached hereto in Exhibit
      A ), as the case may be, in order for the Guarantee of a Guarantor not to
      so violate applicable law.

      Notwithstanding any other provision of this Indenture, stock of any
foreign entity directly held by a Guarantor shall not serve as security for any
of the Securities issued under this

                                       87
<PAGE>

Indenture, other than stock of any such foreign entity representing no more than
65% of the total combined voting power of all classes of stock of such entity
entitled to vote.

      Section 16.4. Successors and Assigns.

      This Article 16 shall be binding upon each Guarantor and its successors
and assigns and shall ensure to the benefit of the successors and assigns of the
Trustee and the Holders and, in the event of any transfer or assignment of
rights by any Holder or the Trustee, the rights and privileges conferred upon
that party in this Indenture and in the Securities shall automatically extend to
and be vested in such transferee or assignee, all subject to the terms and
conditions of this Indenture.

      Section 16.5. No Waiver.

      Neither a failure nor a delay on the part of either the Trustee or the
Holders in exercising any right, power or privilege under this Article 16 shall
operate as a waiver thereof, nor shall a single or partial exercise thereof
preclude any other or further exercise of any right, power or privilege. The
rights, remedies and benefits of the Trustee and the Holders herein expressly
specified are cumulative and not exclusive of any other rights, remedies or
benefits which either may have under this Article 16 at law, in equity, by
statute or otherwise.

      Section 16.6. Release of Guarantor.

      A Guarantor shall be released from all of its obligations under its
Guarantee:

            (a)   in connection with any sale or other disposition of all of the
      Capital Stock of such Guarantor to a Person other than the Company or any
      Subsidiary of the Company;

            (b)   in connection with the sale or other disposition of all or
      substantially all of the assets of such Guarantor, including by way of
      merger, consolidation or otherwise, to a Person other than the Company or
      any Subsidiary of the Company;

            (c)   in the case of any Restricted Subsidiary which after the Issue
      Date is required to Guarantee the Securities pursuant to Section 10.7,
      upon the release or discharge of the guarantee of such Restricted
      Subsidiary of Debt of the Company which resulted in the obligation to so
      Guarantee the Securities; or

            (d)   upon the release of such Guarantor from all of its obligations
      under its guarantee granted in favor of the lenders under the Credit
      Agreement.

      Section 16.7. Execution of Supplemental Indenture for Future Guarantors.

      Each Subsidiary which is required to become a Guarantor shall, and the
Company shall cause each such Subsidiary to, promptly execute and deliver to the
Trustee a supplemental indenture substantially in the form of Exhibit B hereto
pursuant to which such Subsidiary shall become a Guarantor under this Article 16
and shall guarantee the obligations of the Company under the Securities and this
Indenture. Concurrently with the execution and delivery of such

                                       88
<PAGE>

supplemental indenture, the Company shall deliver to the Trustee an Opinion of
Counsel to the effect that such supplemental indenture has been duly authorized,
executed and delivered by such Subsidiary and that, subject to the application
of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and
other similar laws relating to creditors' rights generally and to the principles
of equity, whether considered in a proceeding at law or in equity, the Guarantee
of such Guarantor is a legal, valid and binding obligation of such Guarantor,
enforceable against such Guarantor in accordance with its terms.

      Section 16.8. Execution and Delivery of Guarantee.

      To evidence the Guarantee set forth in this Article 16, each Guarantor
hereby agrees that a notation of such Guarantee shall be placed on each Security
authenticated and made available for delivery by the Trustee and that this
Guarantee shall be executed on behalf of each Guarantor by the manual or
facsimile signature of an Officer of each Guarantor. Each Guarantor hereby
agrees that the Guarantee set forth in Section 16.1 hereof shall remain in full
force and effect notwithstanding any failure to endorse on each Security a
notation of such Guarantee. If an Officer of a Guarantor whose signature is on
the Guarantee no longer holds that office at the time the Trustee authenticates
the Security on which the Guarantee is endorsed, the Guarantee shall be valid
nevertheless. The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the Guarantee
set forth in this Indenture on behalf of each Guarantor.

      Section 16.9. Subordination of Subrogation and Other Rights.

      Each Guarantor hereby agrees that any claim against the Company that
arises from the payment, performance or enforcement of such Guarantor's
obligations under the Guarantee or this Indenture, including, without
limitation, any right of subrogation, shall be subject and subordinate to, and
no payment with respect to any such claim of such Guarantor shall be made
before, the payment in full in cash of all outstanding Securities in accordance
with the provisions provided therefor in this Indenture.

                                       89
<PAGE>

               IN WITNESS WHEREOF, the parties hereto have caused this Indenture
to be duly executed, all as of the day and year first above written.
